Together with the tiller in the store sell a few attachments for the main types of work on the site. This is not enough for the complete mechanization of manual labor on the field. Part of the tools have to buy or do it yourself. Special demand rakes for motoblock. A few simple designs craftsmen can do it yourself.
Purpose of rake and types
To flatten a dug-out vegetable garden and a plowed field, to collect mowed grass, hay, to clean the area from roots and debris will help rakes. They are manual and adaptable to tractors, horse-drawn transport. Suspended equipment for mini-tractors designed for heavy loads, has different designs depending on the work performed. To destination allocate:
- discs - break up clods and soften the soil;
- harrows level the field surface after planting;
- rakes are used for collecting and agitating mowed grass.
The device for disking is usually included in the scope of delivery of the motor-block. Harrows have a simple design, not changing from the time of cultivation with the help of horses and oxen. This is a lattice with sharp teeth at the intersection of lanes. Just animals can pull one harrow, and the tractor - a few.
Tedding equipment and hay collection have various designs. Riders for motoblock craftsmen often do themselves. They adapt them to the specific conditions of the field and technology. The material used is available at hand. Drawing a rake for the motoblock will help in this matter.
Principle of operation
Various types of tools glide over the ground, collecting hay into small stacks. Home-made rakes are characterized by simplicity of design and the absence of complex assemblies and bearings. They rise with the help of a lever and a belt drive, without hydraulics.
For turning, use the wheel rake, rarely spur, angled to the direction of movement. They simply turn the grass, moving it to another place.
Self-made devices are most often made of wire, curved by an arc and welded by welding to a piece of water pipe. On the other hand, fasteners and stops are made to adjust the lift height. Every craftsman selects a practical design for their unit.
Durable alloy steel should be selected for the teeth. Ideally, this springy 60S2A, spring 65G. Such material will not bend or break, hitting a bump, it is strong enough to withstand the load. The ability to spring will allow the long arc to restore its original shape immediately after removal of the load.
The disadvantage of this metal is in specific processing. Bending and welding bars should be heated. To do this, you must have a gas burner in your home workshop. The template for the deformation must be fire resistant. You can use the rim of old wheels.
The rake for the motoblock has to be constantly lifted to leave collected hay. It will be more convenient to do this if you attach a bar with several straight rods between the arcs. They will rise with the collected grass. Then, when the space is filled, the console rotates about the axis with the lever, and the rods help to get rid of the collected mass.
The frame for such a stripper is fixed parallel to the base of the rake. It is made easy, has up to 4 rods. It is enough just to hold the matted mass of plants so that it slips off the arcs.
Hay harvesting device
According to the pick-up principle, you can make a device with your own hands. The drawing is simple. Two rectangular welded wire frames are perpendicular. On one, the grass is collected from long teeth sliding parallel to the ground. The second, vertical, serves as an emphasis, not allowing the grass to wake up.
The advantages of this design - in the ease of manufacture. Pipes easily bend cold. The rods are all smooth, from simple steel, well welded and do not require bending. The disadvantage is low productivity. You can only collect narrow lanes, Work on a flat field, otherwise the bumps will become a serious obstacle.
Farmers who process whole fields are wondering how to make a rake for a walk-behind tractor with a wide swath. A simple solution is to increase the length of the frame and the number of arcs. Then across the field with grass, scattered mower solid carpet, raking hay immediately wide stripe up to 4 meters.
To reduce the load on the frame is divided into 3 parts. The middle console is placed slightly behind the side. To pull such a wide rake can and walker. It is good to use a ½ inch water pipe, a profile for 20 or a corner for 24. They will not sag when the device is filled with hay. For a solid base, a larger cross-section frame is required, and the rakes will be heavy for the motoblock.
Homemade rake for motoblocks
It is possible to make a hinged mechanism for picking grass in the presence of simple equipment in the form of a welding machine, a grinder with a cutting wheel, and a standard home workshop tool. From the materials you will need:
- rod for traction and lift lever;
- corner or pipe;
- bezel for bending;
The wire will need 500-600 mm for each tooth, it depends on its design. You can calculate the number of the length of the console, dividing it by 100 mm - step, and adding one. The working end of the tooth is sharpened and fixed. Using a torch, the wire heats up and fits tightly onto the template. Holds to cool.
Similarly, a loop is made at the top. You can use a thick-walled pipe with an outer diameter of 50-60 mm. Due to the twisted compensator, the arc will spring and last longer. On steels of type 60C and 65G, this can not be done. The rods welded to the console are held together more reliably than various bolted connections.
Wheels fit any, the same and able to withstand the weight of the whole structure. If they have working bearings, do not knock out. Thread the axles in a tight fit and use. Fix the other side of the short rollers firmly in the profile. Weld the console with the teeth with short scraps. The rakes are raised with a lever on the frame with fixation on the rod.
Bearings or cast-iron bushings with fits (tight on the outer diameter and sliding on the inner diameter) should be placed in the wheels. The hole of the lifting lever should be well cleaned so that the irregularities did not make the tease on the axle and did not destroy it.
It is more convenient to begin assembly from a shaft of wheels. To it is welded the design of the thrust, lift and rod for rigidity. Then the size of the mounting profile of the console can be determined in a practical way, so that the ends of the teeth hang 10-15 mm above the ground.
The grass dries faster and will retain its beneficial properties if it is agitated or turned over. The simplest rakes have straight teeth, and the console is at an angle to the rolls. Hay rises from one side and turns to the other.
Practical and convenient rake "sun" for the motoblock make it harder. Their design provides for the rotation of each rake wheel from the drive. This can be done through chain or belt drives. Rotating discs attached to them with bent wires throw grass. They not only turn it over, but also whisk it, increasing ventilation in the roll itself.
Wheel rake for motoblock
Masters called them the sun and make a rake for the motoblock with their own hands. The drawings of the main view resembles a disk with rays that are jokingly bent, as children sometimes draw. The transfer of rotation from the motor to the rake wheels is carried out with the help of a universal joint and a chain. The rake “sun” for the tiller have three disks as standard. It makes no sense to put more quantity, as the engine power is not enough to ensure normal operation.
The console is at an angle to the direction of movement. Dry grass is picked up and folded into more compact swaths. After that, you can collect a narrow grip lift and use hanging devices for baling and pressing hay.
For the selection of hay for the purpose of subsequent compaction used rotary-belt mechanisms with presses and rollers. It is difficult to independently make such a rake for a motorblock with your own hands. The drawings on them are complex, with a large number of bearings and interconnected nodes.
To create a dense bale or winding dry tamped grass with tapes requires a lot of effort. This is mainly done in large farms using a tractor. Attachments in the form of a belt rake and a compactor for the motoblock are commercially available. The teeth are fixed in rows across the belt, which rotates on the rotors. Movement in the capture occurs from the bottom up. Then on the tape hay moves to the bunker. The degree of pressing is small, but loading and storage are simplified.
Conveyor rakes pick up a narrow strip of grass, within a meter. This is limited by the design capability and the tape width. Without a drive can be used for agitating. The disadvantage is the low productivity and complexity of the design.
