Homemade spreader for KMZ 012 and analogues

Good day, dear friends!

The idea of ​​creating a spreader has been hatched for several years. The spreader is an all-metal frame structure, aggregated with a KMZ 012 minitractor and analogues

When creating the ROW, units (rear axle) from the SUZUKI CARRY minibus were used

wheel axle from a walk-behind trailer

conveyor from ROU-6
.
The differential of the bridge was blocked, as a result, began to perform the function of an angular gear. A beater drive sprocket is installed on the left axis, on the right - the feed gear drive gear (conveyor drive). The front shaft is attached to the frame through the carriage, which allows you to pull the conveyor and, through the inserted grease fittings, lubricate the bearings.

The feed mechanism is a makeshift sprocket with a beveled tooth in the direction of the spring-loaded striker. An asterisk is made by hand from rolled steel twenty-two millimeters thick. On the rear shaft are mounted, on bearings, two leads of sheet metal eight millimeters thick, between them a gear of the drive and a spring-loaded hammer, which has the ability to move along the lead from (to) the shaft. He engages with the gear, presses against it due to the spring. When the semi-axis rotates, which engages with the pinion gear, it puts a force on it, the pinion on the shaft, the shaft on the conveyor sprockets. The conveyor moves towards the beater, carrying the load along with it. The axis of attachment of the drive rod of the feed mechanism is offset from the axis of the axis by seven centimeters - this allows you to convert the rotation (axis) in the reciprocating movement of the rod. When the thrust moves in the opposite direction of the hammer, along the beveled gear tooth slides to the next and so on.

The drive to the angular gearbox (minivan bridge) is carried out through the universal joint drive from the VAZ.
On the frame, from the profile pipe, the brackets of the axle of the wheels and sides are welded, which are made of a sheet with a thickness of three millimeters.
As follows from the description, the mechanism for changing the fertilizer application rate by the design is not provided.The application rate is changed by the speed of the tractor and the revolutions of the PTO.

The beater is a shaft of rolled steel with a diameter of forty millimeters (matches the diameter of the mounting bore of the conveyor drive sprocket) mounted on bearings. Metal plates are welded onto the shaft.
