I

FIELD OF THE INVENTION The invention relates to agricultural machinery engineering.

Known fertilizer spreader, comprising a frame on which the body is installed with a feed conveyor, having a Krivoschipno-ratchet drive mechanism and scattering working bodies 1.

The spreader works as follows.

A mass of fertilizers found in the body is fed to a spreading tool, which grinds and spreads the fertilizer over the floor surface.

However, with an increase in the carrying capacity of such a spreader, energy consumption increases, i.e., the torque of the conveyor drive and the spreading working body increases by increasing the body area and the height of the fertilizer layer.

A fertilizer spreader is also known, which includes a frame with support wheels, on which a body is installed with a feed conveyor made of two parts arranged in series and at different levels with alternate drive

FROM KR11VO1nip1 {o- |; gyunn {) from the mechanism, and razopticbiiiaKiLHne workers 2.

This spreader has a torque of 1.) yes TpaiicnopTepOB C11 is twofold due to the fact that iipi is turning the crank; og O to 180 to the spreading tool, the weight of fertilizer that is on one part of the conveyor. First, the rotation of the curve from 180 .10 360 makes a working move for the second part of the trance; 10rter and the mass of fertilizers goes from the first to the second part of the conveyor.

The disadvantage of such a spreader is considerable effort on the spreading workers of the organon, since the mass of fertilizers by one part of the conveyor is fed at the same time but all along the width of the body.

The aim of the invention is to reduce the effort to drive the spreading working bodies.

This is achieved by spreader, equipped with additional, transportable opraHON, while the main and additional transgors are fixed in parallel.

friend with the possibility of alternating. their drive. In addition, the drive transporting working bodies carried out by means of two crank-ratchet mechanisms, the cranks of which are offset from each other by 90 °.

FIG. i shows the fertilizer spreader, side view; in fig. 2 - the same, top view.

The fertilizer spreader includes a frame 1 with support wheels 2, on which the mounted body 3 with a feeding conveyor. The latter is made of two parts 4 and 5 arranged in series and at different levels, each part being made in the form of two parallel branches, respectively, b, 7 and 8, 9. The conveyor is driven from the tractor's power take-off shaft through the propeller shaft 0 and gearbox: 1. From gear

11 torque is transmitted through the shaft

12 and crankshaft 13, connected respectively by means of rods 14 and 5 with ratchet wheels 16 and 17. Mechanisms of drive zeta 6 and 7. The branches 8 and 9 are also driven from the gearbox 11 through the shaft 18 and the crank 19, connected respectively to ha .mi 20

and 21 with ratchet wheels 22 and 23.

For successive switching on of the kg: cd of the transporter branch, the ratchet wheels 6 n 22 have the lower location of dogs 24 and 25, and the ratchet wheels i7 and .3 - the upper position of the dogs 26 and 27 and are mounted on drive shafts 28. 29, 30 l 3; each branch of the conveyor, the tail -; chrivop) types 13 and 19, which are installed; -;; on shafts 12 and 8, the relative speed is shifted (angle of the other in phase by 90. Drive of the spreading / - .- guiding working bodies 32 wasps, most important; -: from the gearbox I through the shaft 33 and the kopta.

In the process of work spreader; - when turning cranks 13 and 19 from O to 90, the pawl 24, turning, enters the drill with the ratchet wheel 6 and pos1), and along with it the shaft 28 of the conveyor branch 6, which feeds the fertilizer spread on it, to the spreading working bodies 32. The latter, rotating, spread the fertilizer layer with a width of half the width of the body. At the same time, the linear speed of movement of the fertilizer mass increases from zero to the maximum value, therefore, the torque of both the drive of the conveyor branch 6 and the drive of the spreading working members 32 increases from zero to the maximum value. The pawl 25 is idle.

With a further turn Krivoshchipov

13 and 19 from 90 to 180 ° the linear speed of the conveyor branch 6 decreases and, consequently, its torque decreases.

drive and drive spreading workers from the maximum value to zero. However, during this period, i.e. when turning the crankshaft 19 from 90 to 180 °, the dog 25 also engages with the ratchet wheel 22 and turns it. and with it the shaft 29 of the conveyor branch 7, which feeds the fertilizers on it, to the scattering workers of the organ m. The latter, without completing the spreading of the fertilizers supplied by the branch 6. spread the fertilizers, but they are fed by the branch 7. If the process of feeding and spreading the fertilizers, being fed by the branch 6, is accompanied by a decrease in torque on their drive from the maximum value to zero, the process of feeding and scattering fertilizers supplied by branch 7 is accompanied by an increase in torque, consumed by their r: drive, from. to the maximum value.

When turning the crank 3 and 19 from 80 to 270 °, the pawl 24, moving in the opposite direction, idle and the mass of fertilizers. The branch C5- on branch 6 remains stationary, and branch 7 continues to reduce the speed of jubilee at a speed of 7 sec., - and the passage on it, to the scattering organs. The torque of the drive of the pa36pacbiBa oi; i, MA organs to the zetwi 7 is reduced by about 14axi ;; the first value to the pool. However, in: this period of rotation of the crank 3, the pawl 26 enters the hook; - ie, with the ratchet wheel 7 and turns it, and with it the shaft 30 of the conveyor branch 8, KCiOjiaH mass of fertilizers, found by her, from the top | 1 I am on a stationary branch of level 6 during this period.

I have a turn (; cranes 13 and 9 from 270 to 360, the pawl 24 continues to idle with c () BepiJ RTb, and the pawl 25 only begins to iBoerpB.pujaTb. At that axis of the branch of the lower part of the conveyor 4 with 1TSYA;: KSJj; BH KHbiMH, followed by cool. l (iy :: omep kx drive and spreading p;; barrel; x X minimum bodies. 3 this time the crankshaft rotation phase continues ;; kindly branch 8 with a decrease in torque moment on its drive, but ipH this dog 27, turning, engages with the ratchet wheel.m 23 and turns it, and with it the shaft 31 trans orterp.oy zetvi 9 which is {1 achinaet apply fertilizers, finding schies thereon from the upper layer to the lower, that is, e. on the stationary phase in the period of rotation 19 krivoschipa branch 7. Then the process is repeated.

With this alternate movement of the branches of each part of the feed conveyor, the force on its drive and drive of the spreading working bodies is reduced, which allows the same power transmission to be used on three types of spreaders, whose carrying capacity is 1: 2: 4.
