Description

The invention relates to agricultural machinery, in particular to machines for transporting rolls of hay and hay.

A device for loading and transporting rolls, adopted as a prototype [A. with. USSR No. 950236, 1982], comprising a frame, levers with clamping elements, a hydraulic actuator with a hydraulic cylinder for turning the levers in a vertical plane and an emphasis. However, this device cannot load and transport haylage rolls using the "haylage in packaging" technology when the mass of the roll reaches 800 kilograms. When loading such a roll, the device will tip over, and during transportation it will be unstable, since it moves on the side of the tractor. In addition, the haylage roll during loading will be damaged by spikes, which is unacceptable.

A vehicle for loading, transporting and unloading rolls is also known [patent RU 2314672 C2, publication date: 01/20/2008, А01D 90/00], comprising a platform with barriers and a loader, consisting of a hoist and grips controlled by hydraulic cylinders of the tractor’s hydraulic system. The disadvantage of this vehicle is the complication of loading rolls due to the insufficiently good overview of the loading process from the tractor cab.

The objective of the invention is to increase the productivity of harvesting hay and hay in rolls.

The problem is solved in that the proposed vehicle for loading, transporting and unloading bales of hay and hay can be transferred from the transport to the working position by turning the trailer relative to the platform using the hydraulic cylinder of the tractor’s hydraulic system, and to give the vehicle stability when loading to the loader shaft attached stand.

Grips of the roll during loading do not clamp the roll from the sides, but support it from the bottom. The loader and platform in design do not differ from similar devices of patent RU 2314672 C2.

New significant features:

- the chassis consists of four wheels mounted in pairs on balancers connected to the platform in the middle;

- the trailer is pivotally connected to the platform by means of a turntable;

- the platform also rests on the trailer through supporting tracks and rollers;

- a trailer hydraulic cylinder is installed horizontally under the platform, the rod of which is connected to the trailer;

- a trailer lock is also located under the platform, with the upper cheek of the clamp bracket tilting, and a wedge is welded to the trailer from above, at the point of entry into the bracket;

- on the lower cheek of the clamp bracket there is a cut with a beveled edge, and the clamping sector has a cut;

- the clamping sector is connected by a rod with eyes, welded to the loader shaft, on which there are curly slots;

- a support is pivotally attached to the loader shaft, also connected to the loader with support springs;

- the roll captures are made without discs and spikes.

New essential features are sufficient in all cases to which the requested scope of legal protection applies.

The set of known and distinctive features of the claimed vehicle is not known from the prior art and does not follow from it in an obvious way.

The new technical result consists in the fact that two vehicles working together provide self-loading, transportation and self-unloading of haylage rolls in a complex of machines using “haylage in packaging” technology, as well as hay rolls. If necessary, the loader can be easily disconnected, and the vehicle can be used to transport various cargoes.

Figure 1 shows a General side view of a vehicle for loading, transporting and unloading rolls of hay and hay with the loader lowered; on figa, 2b - the same, a top view in the transport position and the position for loading; figure 3 - support, view A; figure 4 is a view of B; figure 5 - trailer lock, section DD; Fig.6 is a section EE; 7 is a view of E; on figa, 8b, 8c, 8g, 8d is a loading diagram of the roll.

The vehicle for loading, transporting and unloading hay and hay rolls (Figs. 1, 2) comprises a platform 3, with barriers 4, mounted on the chassis, which consists of wheels 1 and balancers 2. The rear side 6 is pivotally attached to the platform which is controlled by the hydraulic cylinder of the side 5. In front of the platform, a loader 13, controlled by the hydraulic cylinders of the loader 11, is pivotally attached, with grippers 14 controlled by the hydraulic cylinders of the grippers 12. A trailer 17 is attached to the platform pivotally from the turntable 18, the cat The trailer hydraulic cylinder 9 controls the platform. The platform also rests on the trailer through the support tracks 8 and support rollers 7. To unload them during transportation, the trailer lock 10 is used. To ensure vehicle stability when loading rolls to the loader shaft, the support 15 is pivotally attached (Fig. .1, 2, 3), also connected to the loader with support springs 16.

Two eyes 19 are also welded to the loader shaft (FIGS. 3, 4), into the curly slots of which the rod 20 enters. The other end of the rod (FIGS. 5, 6, 7) through the rod spring 32 and the axle 31 acts on the clamping sector 22. K an arm 29 is welded to the platform, and a clamp bracket 23 and a sleeve 28 are welded to it. Axle 27 passes through the holes in the arm and the sleeve, on which the spring of the axis 25 is attached. A snap ring 26 is mounted on the axis on one side and a clamp sector is welded to the other end. . A wedge 24 is welded to the trailer from above, at the point of entry into the bracket.

To load rolls into the field, the machine operator partially lowers the loader. In this case, the eyes rotate from position II in the direction of position 1 (figure 4). The rod slides along the curved slots of the eyes all the way into the ledge "B". Then the thrust with the help of the axis spring wedges the clamping sector (Figs. 5, 6), which, under the action of the sector spring, rotates from position III to position IV. With a further rotation of the eyes, the draft jumps over the protrusion "B" (figure 4), and, moving along the curly slots, it does not affect the clamping sector during loading of the rolls. Then the machine operator using the trailer hydraulic cylinder transfers the unit from the transport position (figa) to the loading position (fig.2b). He drives up to the roll and lifts the trailer with the tractor's hinged system so that the platform slopes back. When approaching the roll, the machine operator using the hydraulic system releases the loader to the ground and pushes it to the roll (figa). In this case, the support becomes vertical without touching the ground. Then the machine operator reduces the grips and lifts the loader along with the roll above the ground (figb). At the beginning of the lift, under the influence of the weight of the roll, the platform leans forward and the support crashes into the ground. In the process of further lifting, the support springs are stretched (Fig. 8c). The roll rolls down from the loader to the platform and rolls along it all the way into the tailgate. At the same time, the vehicle’s center of gravity shifts backward, its front part rises within the range of the tractor’s hinge earring stroke, the support jumps out of the ground and returns to its original position under the action of the support springs (Fig. 8g). The loading of the following rolls is similar. When loading the last roll, there is no significant displacement of the center of gravity of the vehicle, therefore, to return the support to its original position, the machine operator lifts the hinged system of the tractor.

After loading the last roll, the machine operator puts the trailer in the transport position (figa). The trailer is included in the clamp bracket (Fig.5, 6). The loader is lifted to the end, squeezing this roll all the rolls available on the platform. The support rises to the position shown in fig.8d. At the same time, the eyes turn to position II (figure 4) and move the rod. The rod rotates the clamping sector (Fig.6), from position IV to position III. At the same time, it jams the trailer vertically between the lower and upper cheeks of the retainer bracket by means of a wedge (Figs. 5, 6, 7), and horizontally by the clamping sector by moving the “And” cut of the clamping sector along the “K” bevel of the retainer bracket slot. At the same time, the traction spring is compressed, providing a constant clamping of the clamping sector to the trailer when transporting rolls. The clearances "Zh" and "L" provide compensation for the wear of the trailer and the elements of the trailer lock during its operation.

After approaching the place of unloading, the operator lifts the tractor’s hinged system to the end. Using the side hydraulic cylinder, he lowers the tailgate to the ground. Then he jerked the tractor away. In this case, all rolls roll back from the platform.
