Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to reduce energy costs for lifting and collecting cargo. The device is made of a primary boom (OS) 2 and an additional boom (DS) 4 and hydraulic cylinders of drive 3 and 8. OS 2 is mounted on the frame 1 pivotally, its free end is pivotally connected to DS 4 with working members. The frame 1 is attached to the front of the tractor. In the initial position, the OS is installed in the extreme forward position, the DC 4 is lowered and rests on the stop 7 fixed on the tractor, and on the stop 6 fixed on the OS 2. The hydraulic cylinder for lifting the DS 4 is mounted on the vehicle frame parallel to OS 2. During operation, the load is taken by moving the rake grate by the tractor, after which the OS 2 turns around the hinge and rises with a decreasing shoulder of the weight force. At the same time, the valve of the hydraulic control valve for controlling the hydraulic cylinder of the lift DS 4 is installed in the floating position. With a full turn of the OS 2 back hydraulic cylinder rod. the lift of the additional beam is extended so much that its length becomes equal to the length of OS 2. In this position, the length of the lift of the DS 4 is fixed by setting the valve of the hydraulic distributor in the neutral position. In this case, a parallelogram is formed, the windings, when OS 2 is rotated, move DS 4 in a plane-parallel motion, which ensures the forward load at one most characteristic height for loading most cargoes. The presence of stops on the tractor and. OS 2 allows one to perceive dynamic loads not on the hydraulic cylinder, but on the tractor frame. 2 Il. -eight . CL / (L 00 4 SB

Description

FIG.

The invention relates to agricultural machinery and can be used in loading and unloading machines.

 The purpose of the invention is to reduce energy costs for lifting and collecting cargo. Fig. 1 shows a diagram of a load handler with a lowered rake grille, side view; Fig. 2 shows the technological process of lifting and delivering the cargo during loading (II, III - IV, V - the position of the cargo in the loading and ricketing processes).

Loading: the infrared stacker consists of frame 1, main boom 2, hydraulic cylinder 3 of the main boom drive, additional boom 4, working body - rake lattice 5, stops 6 and 7, hydraulic cylinder 8 of the additional boom drive.

The frame on: a small stacker 1 is fastened to the frame of the tractor and is the carrier part of all components and parts of the stack-loader with the main boom 2 attached to the frame 1 pivotally at the point O (). Pivotally with the main boom (Fig. 1) on one of its ends: the cylinder of hydraulic cylinder 3 is connected, on the other, an additional boom 4. The axes of these hinges are located in the horizontal plane and provide I with the main and additional arrows along the tractor, to the free I end additional boom pivotally; fastened rake grille 5.; The loader works as follows.

In the initial position I (Fig. 1), the main boom 1 is in the extreme forward position, the hydraulic cylinder rod 8 is fully retracted into the cylinder, the additional boom 4 is supported on the stops 6 and 7. The rake with 5 teeth rests on the soil surface. By moving the tractor forward, the load is picked up on the rake grille and fixed on it with a special device (not shown). The valve of the hydraulic distributor, acting on the hydraulic cylinder 3, rotates the base-: Ngayu boom relative to the hinge O (figure 2) to the right. In this case, the control valve of the hydraulic cylinder-8 (Fig. 1) is set to the floating position. As the secondary boom hits the support 6, the angle between it and the main Arrow remains in the process of turning the main

the boom, the rod of the hydraulic cylinder 8 is pulled out of the cylinder. In the extreme right position

the boom (fig. 2), the additional boom occupies the position ACj and the load is raised to position II. The control cylinder of the hydraulic cylinder 8 is set to the neutral position, thereby fixing its length. When the load is in position II, the length of the hydraulic cylinder with the stem depressed is equal to the length of the main boom, i.e. OA is equal and parallel to CT, and so

as OK, then obtained by the parallelogram OctA. The OA and ct levers are made of such length, and the boom of the AU is located so that in position C the load is at a height that is optimal for loading most cargoes (for example, 4–4.5 m). It is located in close proximity to the tractor, which can be moved with it to the place of loading.

At the place of loading, the tractor is stopped by a hydraulic cylinder 3 (figure 1), turning the main boom around the hinge O (figure 2), the load is fed from position II to position III to the left. Lower the load by turning the additional boom around point B by the hydraulic cylinder 8 (FIG. I).

The rake grating is returned to the initial position by turning the main boom to the extreme left position and lowering the additional boom all the way down.

At the completion of the mow in position II, the cargo is delivered to the ricks, the tractor is stopped. By the hydraulic cylinder 8 (FIG. 1), the cargo is lifted to the required position. my height to position IV (figure 2), then by turning the main boom to the left, the load is fed to the rick, the position

V. After the tractor leaves the ricks, the rake lattice is lowered to the initial position by turning the main and additional boom to position I. Since the load is fed while the tractor is stationary, the dynamic loads on the system as a whole are reduced, this allows you to increase the amount of load forward without increase the danger of the loader. In the transport position rake rake up to level. The eye of the tractor driver by turning the main boom. With that extra stre314

The truck is on a stop, which provides a more stable movement of the tractor with a loader.
