Abstract

The invention relates to agricultural machinery and allows to increase productivity in the transport of coils formed from hay materials, due to their rational placement in the form of diamond-shaped blocks of four coils in a trough-shaped body. The device for placing the rolls contains a forked grip, the lever of which is mounted in front of the platform and interacts in the initial position with the stop located in the front part of the transporter frame. The sidewalls of the frame have grooves in which the flaps with the possibility of translational movement in these grooves are formed, forming a longitudinal channel in the middle part of the body. Moving the blocks of rolls along the platform provides a sealing wall that, when using the levers and the hydraulic cylinder, can perform reciprocating movements. 2 sec. and 2 3. p. f-ly, 3 ill. about

Description

one

The invention relates to agricultural machinery, in particular to methods for placing rolls on the platform of the transporter and devices for their implementation.

The aim of the invention is to increase productivity.

FIG. 1 shows a device for carrying out a method for placing rolls on a carrier platform, front view; in fig. 2 - transporter, side view; in fig. 3 - the same, top view.

The method includes the selection, lifting and laying of rolls on the platform and each other. In this case, the rolls are placed on the platform in the form of diamond blocks consisting of four rolls.

The device for placing the rolls on the platform of the transporter consists of a chute mounted on the wheel forks of the forks and a mechanism for moving the rolls along the platform.

The conveyor chute consists of two parallel sidewalls 1, connected in front of the crossbeam 2, which are used to accommodate the bottom row of rolls. The upper parts of the sidewalls 1 are completed with supports 3, which are made in such a way that they form cells together with the lower row of rolls (Fig. 1) for laying the upper rows. In the grooves of the sidewalls 1 are installed with the possibility of translational movement of the shutter 4, which are held by the latches 5.

The rear ends of the sidewalls 1 are closed by a strap 6 (FIGS. 2, 3) with the help of clips 7. On the outer sides of the sidewalls 1 are the axles 8, on which the forks 9 are mounted, resting on the axles of the wheels 10. The forks 9 are articulated with the sidewalls 1 and With the help of hydraulic cylinders 11, it is possible to perform mating movements together with the wheels 10 around the axis 8.

Fork gripper consists of a lever 12, moving in the transverse plane

through the hydraulic cylinder 13, at the end of which are located the fingers 14 and 15. In the original

the position of the lever 12 can interact with the stop 16.

The mechanism for moving the rolls along the platform consists of a sealing wall 17 mounted on the rod 18, which is held in the guide 19 and pivotally connected to one of the ends of the single-arm lever 20 connected to the hydraulic cylinder 21. The sealing wall 17 can reciprocate movement using these elements of the lever system, driven by a hydraulic cylinder 21.

The device operates in an aggregate with a tractor 22 and is pivotally connected to the rear axle 23 of tractor 22 by a latch 24. T he ha 23 can move vertically using a hydraulic actuator mounted on tractor 22 (not shown).

The device for placing the rolls on the carrier platform by the proposed method works as follows.

The operator lowers the lever 12 by means of the hydraulic cylinder 13 until the finger 14 contacts the soil and rolls over the roll. FIG. 1, the initial position of the aforementioned elements is indicated by a dotted line. In this case, the roll hits the lever 12, which is prevented from being deformed by the stop 16. The captured roll is raised to a position above the transport body 1. in which it rolls under its own weight from the finger 15 and falls into the groove formed by the sidewalls 1 and the flaps 4. The process is repeated. The second roll, the pad on the first, due to the instability of the position rolls down from it and occupies one of the cells longitudinally formed between the previously laid roll and the supports 3 of the sidewalls 1. The third roll will likewise be placed in the opposite cell. The second and third rolls form a depression between them, where the fourth roll is placed. The formed block of four rolls is moved to the rear of the body by means of a sealing wall 17, which is driven by a hydraulic cylinder 21 and a lever system (Fig. 2).

Moving the block along the platform is carried out on a chuck equal to the length of the roll. The sealing wall 17 is returned to its original position, and the formation of the next block of four rolls is carried out in the previously described sequence. The process is repeated until the transporter body, limited by the bar 6, is completely filled with blocks of four rolls.

Then the transporter filled with rolls is transported to the place where the rolls are prepared.

and unload. For this, the transporter body is lowered onto the ground, pushed into the wheels 10 by means of hydraulic cylinders 11, acting on the forks 9, and lowering the tractor 23 of the tractor 22. In this case, the lower row of rolls located in the longitudinal channel formed between the flaps 4 to the ground. The flaps 4, having the possibility of translational movement in the grooves of the sidewalls 1, are displaced, improving the contact of the lower row rolls with the soil when lowering

5 body to the ground. At the same time, the lower row rolls begin to lift the upper row rolls, as a result of the cohesive force of the lower row rolls with the soil will exceed the adhesion force of the leach rolls to the platform, which allows

0 unload the transporter by pulling it out of the rolls with the help of the tractor 22, having previously uncoupled the bar 6.

The unloaded transporter is reversed into transport

5 position, set the bar 6 and the device is again ready to work.
