Description

The invention relates to material handling equipment. primarily for attachments to mobile loading devices, and is intended to empty containers filled with bulk or lumpy cargo, e.g. vegetables.

It is an object of the further invention to increase efficiency by allowing containers to be picked up from the stack.

Figure 1 shows a tipper container, General view; figure 2 - node I in figure 1 with an unsecured container; on figs - node I in fig. 1 with the container locked; figure 4 is a section aa in figure 2; figure 5 is a section bB in figure 1.

The container tipper includes L-shaped forks 1 mounted on the cantilever ends of the brackets 2 mounted on the load carriage 3 of the lifting device by means of horizontal axles 4 with the possibility of rotation in the vertical plane of the drive 5. Axes 4 are located perpendicular to the longitudinal axis of the forks 1 in the plane of the latter - shields with respect to the transverse axis of the latter towards the load carriage 3. The drive 5 includes a power cylinder 6, the casing of which is fixed to the load carriage 3, and a cable block system, block 7 which is fixed on the rod 8 of the cylinder 6, and the cable 9, the envelope of the block 7, is fixed one | the end on the load carriage 3, and the other through the block 10, mounted on the carriage 3, brought to the eye 11, which is mounted on the forks 1, and attached to it. On the vertical part of each pitchfork 1, a set of 12 clips 13 is fixed. Each of the clips 13 is spring-loaded 14. At the end of each pitchfork 1, a lever 15 is located inside it, on which

with the help of the axes 16, a set 17 of the latches 18 is fixed. Each of the latches 18 is spring-loaded with a spring 20. The lever 15 has a stop 21, is connected via the axis 22 to the rod of the power cylinder 23, the axles 24 are fixed on it. They can interact with the grooves 25, made in the form of 1. A section 26 of the bottom of each fork 1 in the area of the lever 15 is pivotally mounted on the fork on axes 27 and spring-loaded relative to the fork by spring 28. One of the shoulders 19 of the set 17 of latches 18 is equipped with a spring 29 that squeezes it from the stop 21 of the lever 15 . On the second shoulder 30 sets of 17 retainer in 18, a flexible element (cable) 31 is fixed at one end, the second end of which is passed along the lever 15 and is connected through an spring 32 to an additional stop and spring-loaded spring 33 relative to the forks of the stop 34. To support the cable 31, rollers 35 are mounted on the lever 15. In front of the movable stop 34, an additional fixed stop 36 is installed in the fork. The spring stiffness 29 of the set 17 of latches 18 is greater than the stiffness of the spring 33 connecting the flexible member 31 with the movable stop 34.

The shoulder 30 of the set 17 of latches 18 is provided with a hook 37 for engaging with the pitchfork bottom portion 26. In the pitchfork bottom portion 26, grooves 38 are made for the stops 21 of the levers 15.

Tipper works as follows.

The loader, on which the tipper is mounted, drives up to the stack and enters the forks 1 under the container 41. The sets 17 of the latches 1.8 together with the levers 15 are recessed in the forks 1. When the forks 1 are inserted under the container 41, part of the latches 13 rests against the boards 39, which the container is sheathed and, overcoming the force of the springs 14, is recessed in the housing of the set 12. Those of the latches 13 that fall between the boards 39, resting against the frame 40 of the container 41, fix it from vertical movement. After the forks 1 are inserted under the container 41, the container is lifted and transported from the stack. The actuators 23 are turned off to expel the rods. The levers 15 are moved forward, and then, due to the fact that the axis 22 in the vertical plane is located below the axes 24, they rotate all the way into the frame 40 of the container 41, while the axles 24 are moved relative to the grooves 25. When the levers 15 are moved forward, together with them the ends of the cables 31 are also fixed, fixed on the shoulders 30 of the sets of 17 clips 18.

Moving, the cables 31 first stretch the springs 33. During the rotation of the levers 15, the movable stops 34 move and abut against the fixed stops 36,

The stiffer springs 39 begin to stretch. When the springs 29 are stretched, the sets of latches 18 rotate until they contact the stops 21. At the final stage of rotation, the springs 32 are stretched. In the rotated position of the set of latches 18, the part of the latches that abuts the boards 39, overcoming the force of the springs 20, are recessed in the housing of the kit 17, and those of the latches 18 which are placed between the boards 39, resting against the frame 40 of the container 41, fix it from vertical movement. During the movement and rotation of the levers 15, the sections 26 of the forks are rotated relative to

0 axles 27, skip levers 15.

The container 41 is transported to the place of unloading (e.g., to a car body). Here it is raised to the required height and placed above the body. Thereafter

5 turn on cylinder 6 to retract the rod 8, the cable 9 is released, and the fixed container together with the forks 1 is tipped by turning around the axles 4. As a result of the tipping, the container os0 is freed from the load, and by turning the cylinder on to push the rod, the forks 1 are returned to the starting position. The empty container is delivered to its place of storage or filling and freed from

5 retainers 18 by engaging the cylinders 23 to retract the rods. After the rods are retracted, the levers 15 with a set of 17 latches 18 return to their original position (they are recessed in the forks). In this kit

0 17 of the latches 18 is deployed by the spring 29. The cable 31 is returned to its initial position by the spring 33. The hooks 37, which are provided with the sets of 17 latches 18 in the initial position, lock the lower ones

5 sections 26 of the bottom of the pitchfork, Pitchfork 1 is pulled out from under the container, and the loader leaves for the next container.
