Abstract

The invention relates to the equipment of forklift trucks, is intended for loading and unloading operations with bulk cargo and can be used in various sectors of the national economy. The purpose of the invention is to increase productivity. On the L-shaped quick-release frame 3, the bucket 6 is rotatably mounted about the axis 5, and the drums 8 and 9 are mounted on the vertical part of the frame. A cable 22 is wound on the main drum 8, which is fixed at one end to it, and to the other end 23, installed on the mast loader. At the end of the lever 11 is fixed a cable 20, missed under the bucket 6, wound on the drum 9 and fixed on it. On the rear wall of the bucket 6 is mounted on the axis 26 @ -shaped lever 27, on which is fixed a horizontal finger. The lever 27 is spring-loaded spring 32. The lower parts of the levers 27 fix bucket 6 when it is filled and lifted into the transport position by means of the stop 34. At the initial moment of rotation of the bucket, the flexible element (cable) 20 acts on the horizontal finger of the lever 27, releasing it from the stop 34. hp ff, 6 ill.

Description

FIELD OF FORKLIFTS, SERVED FOR jc

loading and unloading and transport operations with bulk cargo and can be used in various industries of the national economy.

The purpose of the invention is to increase productivity.

Figure 1 shows the bucket working body, side view; figure 2 - the same, when unloading the bucket; on fig.Z - section aa in figure 2; in Fig. A, node I in Fig. 1; in fig. 5, view B in FIG. four; figure 6 - section bb In fig.Z.

The bucket tool body contains a L-shaped frame 3 rigidly fixed on the forks 1 of the loader 2. The frame 3 is fixed relative to the forks 1 by clamps A. At the end of the frame 3 the bucket 6 is rotatably mounted about the axis 5, and the main drum is installed at the end of its vertical part 7 8 and an additional drum 9, larger in diameter. On the bucket 6 on axis 10 a lever 11 is mounted, at the end of which rollers 13 are rotatable about axis 12, the lever is equipped with arms 1A mounted on it by means of axes 15. The second ends of stage 1A end axles 16, set with the possibility pozvratno- translational movement in the slots 17 of the guide 18 fixed on the bottom of the ladle 6. The frame 3 is provided with a guide 19 for cooperating with the rollers 13.

At the end of the lever 11, a flexible element (cable) 20 is fixed next to the rollers 13, the latter is passed under the bucket, bends around the guide 21 of the lever 11, is wound on an additional drum 9 and fixed on it. A flexible element (cable) 22 is wound on the main drum 8, fixed with one end to it, and fixed with a second end to the cable

not 23 installed, for example, on the mast 2A loader0

On the cable 22, a spring 25 is fixed on its section from the eyelet 23 to the main drum 8, the cable 22 passes inside the spring 25. The length of the cable 22 inside the spring 25 is longer than the spring in a compressed state.

On the rear wall of the bucket 6 is mounted on the axis 26 of the J-shaped lever 27. There may be two. They can be two shoulders. The lower parts (shoulders) of the 28 arms 27 are j-shaped. A horizontal finger 29 is attached to them, which can connect them together. Roller 30 can be mounted on this finger. The arms or their upper arms 31 are spring-loaded with springs 32 relative to the bucket 6. There are stops 33 fixed to the bucket to limit the angle of rotation of the levers. On the vertical part of the frame 7, there are fasteners FOR for interaction with the horizontal part 28 of the levers 27.

The working body works as follows.

The frame 3 is mounted on the fork 1 of the loader 2 and fixed relative to their clamps A. The cable 22 is fixed on the eye 23 mounted on the mast 2A of the loader. The device is lifted to the transport position and the loader approaches the load being loaded. Here, the forks 1 are lowered to the down position and the bucket 6 is filled with a load. The bucket rises to the transport position. In the process of filling and lifting the bucket, the horizontal parts 28 of the levers 27 are meshed with the backs FOR. This prevents the bucket from unloading at the beginning of its lifting to the transport position,

The loader drives up to the place of unloading of cargo (for example, to the car body) and raises pitchfork 1 to the top5153

her position. In doing so, the cable 22 rotates the main drum 8, which rotates the additional drum 9 rigidly connected with it. The cable 20 is wound on the additional drum 9. and acts on the roller 30, while the levers 27 stretch the springs 32, and their lower parts 28 come out of the engagement with the stops 34. Next, the cable 20 rotates the bucket 6 on the axis 5 forward. Due to the larger diameter of the additional drum 9 as compared to the main drum 8, the loss of lift height of the loader for unloading the bucket 6 is reduced by as many times as the diameter of the additional drum 9 is larger than the diameter of the main drum 8.

At the initial moment of rotation of the mat 6, the cable 20 acts on the guide 21 of the lever 11. Then the cable 20 begins to act on the end of the lever 11 which turns in the direction of the loader. With JTOM, the axles 16 tchg 14 move in the grooves 17 of the guides 18. The gates 14 fix the lever in a position that ensures the maximum angle of rotation of the bucket (the center of gravity of the bucket at its maximum angle of rotation should be offset from the axis 5 to the side of the loader).

The load is poured out of the bucket 6, the forks 1 of the loader are lowered down. When the bucket 6 is lowered, the rollers 13 rolls along the guide 19 and the lever 11 with the rims 14 returns to its original position. In the horizontal position of the bucket, the cable 20 is glorified ,, and the springs 32 insert the horizontal parts 28 of the J-shaped levers 27 into engagement with the stops 34. The stops 33 hold the levers 27 in the process of turning the bucket in one position.
