Together with the motoblock in the store, they sell several attachments for the main types of work on the site. This is not enough for the full mechanization of manual labor on the field. Part of the tools have to be bought or done by yourself. Special rake rake for a motoblock. A few simple designs can be made by craftsmen.
Rake assignment and types
Align a dug garden and a plowed field, collect chopped grass, hay, clean the site of the roots and debris will help rake. They are manual and adaptable to tractors, horse transport. Suspended equipment for mini-tractors is designed for heavy loads, has different designs depending on the work being done. By designate:
- disks - break up clods and soften the soil;
- harrows align the surface of the field after planting;
- the rake is used to collect and tinker the mown grass.
The disk drive is usually included in the delivery kit of the motor block. Harrows have a simple design that does not change from the time of processing the land with the help of horses and oxen. This is a lattice with sharp teeth at the intersection of strips. Simply animals can pull one harrow, and a tractor - a few.
Tedding and collecting devices have different constructions. Rakes for motoblock craftsmen often do themselves. They adapt them to the specific conditions of the field and technology. The material is used available at hand. Drawing rake for motoblock will help in this matter.
Principle of operation
Various kinds of adaptations slide teeth over the ground, collecting hay in small haystacks. Homemade rakes are distinguished by their simple design and the absence of complex knots and bearings. They are raised by means of a lever and belt transmission, without hydraulics.
For tedding use the wheel rake, less often spout, turned at an angle to the direction of movement. They simply turn the grass over, moving it to another place.
Homemade devices are most often made of wire, arched and welded to a piece of water pipe. On the other hand, fasteners and stops are used to adjust the lift height. Each craftsman selects a practical design for his unit.
For teeth, you must choose a strong alloy steel. Ideally, it is springy 60S2A, spring 65G. Such material will not bend and break, jumping on a bump, it is strong enough to withstand the load. The ability to spring will allow a long arc to restore its original shape immediately after removing the load.
The disadvantage of this metal is in specific processing. Bend and weld the rod should be heated. To do this, you must have a gas burner in your home workshop. The template for deformation should be fire resistant. You can use the rim of old wheels.
The rake for the motoblock has to be constantly raised to leave the harvested hay. Doing this will be more convenient if you attach a bar with several straight rods between the arcs. They will rise together with the collected grass. Then, when the space is full, the arm turns with the lever relative to the axis, and the bars help to free themselves of the collected mass.
Frame for such a stripper is attached parallel to the base of the rake. It is made easy, has up to 4 rods. It is enough just to hold the tangled mass of plants so that it slides off the arcs.
By the principle of pick-up, you can make the device yourself. Its drawing is simple. Two rectangular frames with welded wire are perpendicular. One gathers grass from sliding parallel to the ground long teeth. The second, vertical, serves as an emphasis, not allowing the grass to wake up.
The advantages of this design are in the simplicity of manufacture. The pipes are easy to bend cold. The bars are all flat, from simple steels, they are well welded and do not require bending. The drawback is in low productivity. Collect only narrow strips, Work on a flat field, otherwise hummocks will become a serious obstacle.
Farmers who process whole fields are wondering how to make a rake for a motoblock with a wide grip. A simple solution is to increase the length of the frame and the number of arcs. Then, along the field with grass, scattered mower with a solid carpet, the hay is raked at once with a wide strip up to 4 meters.
To reduce the load on the frame, it is divided into 3 parts. The middle console is placed slightly behind the side. Drawing such a wide-grab rake will also be a motoblock. It is good to use a ½-inch water pipe, a profile of 20 or a corner of 24. They will not bend when the fixture is filled with hay. For a solid foundation, a larger frame is required, and the rake will be heavy for the motoblock.
Homemade rake for motoblocks
A hinged mechanism for collecting grass can be made with simple equipment in the form of a welding machine, a grinder with a cutting circle and a standard tool of the home workshop. The materials will need:
- rod for traction and lifting lever;
- corner or pipe;
- rim for bending;
Wire will need 500-600 mm for each tooth, it depends on its design. You can calculate the amount by the length of the console, dividing it by 100 mm - step, and adding one. The working end of the tooth is sharpened and fixed. With the help of the burner, the wire heats up and fits tightly onto the template. Holds until completely cooled.
Similarly, a loop is made at the top. A thick-walled pipe with an external diameter of 50-60 mm can be used. Thanks to the swivel compensator, the arc will spring and last longer. On steels type 60C and 65G this can not be done. Welded to the console rods are more reliable than the various bolted connections.
Wheels fit any, the same and can withstand the weight of the whole structure. If they still have working bearings, do not knock them out. Protect the axles by a tight fit and use. The second side of the short rollers is fixed rigidly in the profile. Console with teeth, weld with short cuttings. Raise the rake lever on the frame with a fixation on the rod.
In the wheel, you must put bearings or a cast-iron bush with plantings (tight on the outside and sliding on the inside diameter). The opening of the lifting lever should be well cleaned, so that the irregularities do not seize the axle and do not destroy it.
It is more convenient to start the assembly from the shaft of the wheels. It is welded to the design of traction, lift and rod for rigidity. Then the size of the profile of fastening the console can be determined in a practical way, so that the ends of the teeth hang over the soil for 10-15 mm.
The grass will dry faster and retain its useful properties if it is tied or rolls roll over. The most simple rakes have straight teeth, and the console is at an angle to the rolls. Hay rises from one side and turns over to the other.
Practical and convenient rake "sun" for motoblock make it more difficult. Their design provides for the rotation of each rake wheel from the drive. This can be done through chain or belt drives. Rotating, the discs attached to them by bent wires toss the grass. They not only turn it over, but also whip it, increasing the ventilation in the roll itself.
Wheeled rake for motoblock
The masters nicknamed them the sun and make a rake for the motoblock with their own hands. The drawings of the basic form resemble a disk with rays, jokingly bent, as children sometimes paint. Transmission of rotation from the motor to the wheels of the rake is carried out with the help of a cardan and a chain. The rake "sun" for the motoblock has three discs as standard. There is no sense in putting more quantity, because the engine power is not enough to ensure normal operation.
The console is at an angle to the direction of travel. Dry grass is selected and folded into more compact rolls. After this, it is possible to assemble with a narrow-grab lift and use hanging devices for baling and baling hay.
For the selection of hay for the purpose of subsequent compaction rotor-band mechanisms with presses and rollers are used. It's hard to make such rakes for a motoblock with your own hands. The drawings on them are complex, with a large number of bearings and interconnected nodes.
To create dense bales or winding dry, compacted grass, tapes require a lot of effort. This is mainly done in large farms with the help of a tractor. Attached equipment in the form of belt rake and sealant for the motor block is available. The teeth are fixed in rows across the ribbon, which rotates on the rotors. Movement during capture is from the bottom up. Then the hay moves along the belt to the hopper. 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 and width of the tape. Without a drive can be used for tedding. The disadvantage is the low productivity and complexity of the design.
