How to assemble a wood concrete wood chipper with your own hands according to the drawings

For those who enjoy do-it-yourself projects, building a wood concrete wood chipper can be a fun and fulfilling undertaking. This adaptable instrument is made to break down wood into small chips that can be utilized in concrete mixtures and other applications. Building your own chipper and improving the functionality of your workshop can be accomplished by following a set of comprehensive drawings and instructions.

This project starts with assembling the required supplies and equipment. Along with some basic tools like a drill and saw, you’ll need welding equipment and a combination of metal and wood parts. Your construction process will be guided by the design plans, which will make sure that every component fits together securely and works as intended.

The cutting mechanism is one of the main parts of the wood concrete wood chipper. The larger wood pieces are broken down into smaller, easier-to-manage chips by this portion of the machine. The performance and safety of the chipper depend heavily on the precise assembly and alignment of the blades. Paying close attention to detail at this point will result in a machine that is dependable and efficient.

Your wood chipper can be a useful addition to your concrete projects once it is assembled. You can reduce material costs and tailor the mix to your unique requirements by making your own wood chips. Building this tool offers a hands-on, educational experience in both metalworking and woodworking, regardless of your level of experience.

Wood chipper for making wood concrete: operating principle

Prior to beginning the manual construction of a wood chipper for wood concrete, you should thoroughly examine the drawings, give careful thought to the layout, locate all required parts, and only then put them all together. The machine’s primary parts are a rotor with blades and hammers, and a chopping disk with knives. The working shaft, which is powered by a pulley and belted to the engine, is where the disk is positioned. The motor is fixed on a frame, and the shaft rotates on two roller bearings.

The raw materials are manually fed; waste is pulled under hammers and knives, and the raw materials to be processed are thrown into the receiving hopper. The chips are sent through a sieve equipped with blades during the final processing step, and they emerge from the chip cutter through a dedicated unloading aperture. To facilitate easy and secure feeding of raw materials, the receiving hopper at the entrance is designed in the shape of a funnel.

• Motor power – about 7.5 kW.
• Motor rotation speed on the working shaft – maximum 3000 rpm.
• The optimal rotation speed of the shaft where the disk with knives is mounted is 1500 rpm.

The productivity of the machinery increases even though it’s likely that raw wood materials will start to turn into dust rather than the appropriate-sized chip if the shaft rotates more frequently.

Main units of the wood chipper, drawing

Drawings can be used to construct a DIY rotary hammer crusher. Because the material may vary, the parts’ dimensions do not always match those that are specified. The crusher is composed of multiple main parts and operates on a 220-380 V power supply.

• Metal body with a folding/removable casing.
• Bits with hammers that rotate absolutely freely and are responsible for creating chips. Must be divided into sectors by bumpers.
• Knives fixed on the disk.
• Calibrating sieve with holes of 15-20 millimeters.
• Bunker where wood raw materials are fed.

Numerous working drawings are available online; while some may differ in terms of size or specific units, the device’s basic operation remains the same. The equipment receives 220 V power from the engine, which rotates the drum containing the knives via a pulley and shaft and a V-belt drive. The feed bunker receives raw wood materials and processes them into wood chips that can be up to 25 and up to 5 millimeters wide—the ideal size for arbolite.

Making a wood chipper for arbolite with your own hands

Before you can begin assembling the wood chipper made of arbolite, you must first prepare all the components. While some components can be made on your own, others are worth searching for.

Disk with knives

The disk should have a maximum diameter of 30 to 35 centimeters and a maximum thickness of 2 centimeters. The disk is made heavy because it should operate on the same principles as a flywheel, which eliminates the possibility of hard or large raw material pieces jamming.

You can make it from a piece of sheet steel or a metal blank. Then, you can saw one central hole in the part (to seat the shaft and account for keyway fastening), as well as multiple mounting holes and three grooves through which the wood pieces that have been cut will be sent beneath the revolving hammers.

To make knives, take car springs, drill two holes in each knife, then countersink them (you must recess the screw heads as much as possible). Then, use bolts with a hexagon-specific countersunk head to fasten the knives to the disk, allowing you to create a tight and dependable connection. Furthermore, when the nuts are tightened from the opposite side, the bolts in this instance will be unable to rotate.

Hammers

Within the rotor is a flat plate that can have a thickness of up to 5 millimeters. Since the hammers are in charge of further grinding the raw materials, it is preferable to purchase them already assembled. There should be 24 millimeters between the hammers in the crusher directly next to each other.

A sieve for a brush cutter

A metal cylinder with a diameter of 30-35 centimeters made of 94-length metal sheet is taken and used to create a sieve, inside of which is located a rubber chamber.two to one hundred centimeters.

Cells in the cylinder itself have a cross section of 8–12 millimeters; it is preferable to use a punch or core rather than a drill to cause the cells’ edges to tear or become sharp.

Protective casing, funnel, reception hopper and frame

Sheet iron with a thickness of 8–12 millimeters can be used to make a protective casing for the receiving bin’s hopper. The drawing is followed when cutting and welding sheets to size. Sections are cut in accordance with previously established dimensions and "patterns" (thick cardboard can be used to prepare them ahead of time). Pipes, channels, or angles are used to create stiffeners.

The ideal diameter of the flywheel is reduced by roughly 3-5 centimeters because the cutting unit itself should not even slightly adhere to the housing of the unit; rather, it should be freely positioned inside the housing.

The primary components of the crushing unit are the shaft journals, which house the hammers, cutting disc, and support bearings. It only takes holes to be cut in input/output sockets meant to feed raw materials and chips out to form the working shaft.

The raw material receiving hopper is welded to the housing at an angle. The last step involves mounting mechanical or electric drives. First, an electric motor is fastened to the frame, followed by pulleys of the necessary size, and finally, a belt drive connects each unit. Typically, standard automobile belts with the proper diameter are utilized for this function.

Engine

The type of engine used in the wood chipper will determine its productivity and operating costs. Although it is lighter and produces less noise than an internal combustion engine, an electric motor is thought to be the most environmentally friendly choice. However, its power output is also lower. It is important to keep in mind that network voltage surges can have an impact on an electric wood chipper.

A gadget with a stronger gasoline engine will run more efficiently for longer periods of time and won’t need an outlet or network. However, an internal combustion engine needs to be refueled frequently, requires constant maintenance, and produces a lot of noise pollution.

You can use a coaxial scheme instead of a belt connection, mounting the shaft connection through a coupling, as long as the assembled wood chipper for arbolite is precisely designed and there is no run-up in coaxiality.

Converting wood waste into practical concrete additives can be a satisfying project when you build your own wood concrete wood chipper. With the help of thorough drawings and clear, step-by-step instructions, this guide will walk you through the entire process. You will learn how to assemble the chipper using common tools and materials, making it easier to handle construction projects with sustainable practices, whether you are an experienced do-it-yourself enthusiast or are just getting started.

Assembling the wood chipper units

To guarantee proper equipment operation, a specific order must be followed when assembling a wood concrete wood chipper.

• First, proceed to the chopping block: put the bearings on the shaft, then the disk and knives, hammers.
• Now you need to prepare the housing for installation: make holes for the shaft / bunker for receiving raw materials, unloading chips.
• Next, drill holes for the assembly bolts, weld the funnel of the receiving bunker at an angle to the housing.
• The drive is assembled as follows: attach the engine to the frame, mount the pulleys, put on the belt.
• Now you need to attach the chopping block to the frame, close it with a protective casing to eliminate the risk of accidents.
• You can do an idle test run.

Constructing a wood concrete wood chipper at home can be a fulfilling endeavor that blends imagination and usefulness. You can build a tool that assists in turning wood waste into useable chips, which are useful for gardening, landscaping, or even as a foundation material for concrete mixes, by adhering to thorough drawings and instructions. Key parts of the process, including the discharge system, motor, frame, and blades, must be assembled carefully with attention to detail to guarantee both efficiency and safety.

The building process emphasizes how crucial it is to use the appropriate supplies and equipment. When building and putting together the chipper, it is important to take into account the distinct qualities of both wood and concrete. For example, the combination of wood’s flexibility and concrete’s durability provides a well-balanced solution for building a machine that is both robust and flexible. For the chipper to work well and last a long time, the mechanical parts must be fitted and tightened.

This project cannot place enough emphasis on safety. To prevent possible injuries, appropriate safety equipment, such as gloves and eye protection, should be worn at all times. Accidents during operation can also be avoided by carefully following the assembly instructions and verifying all connections. Regular maintenance checks are also necessary to maintain the chipper’s functionality and increase its lifespan.

Building your own wood concrete wood chipper gives you practical experience in addition to a useful tool. This project offers a hands-on approach to learn about mechanical assembly, woodworking, and material properties. Constructing a DIY chipper or aiming to decrease wood waste in an environmentally friendly manner can both be rewarding and educational.
