The device for unloading containers contains posts 7, on which in the upper part a shaft 6 with pitchforks 1 mounted on it is rotatably mounted, on its vertical parts there are floating pins 2. Container 3 is fixed on pitchforks 1 by floating pins 2 and LJ - shaped handle, fixed ends on the side walls of the container 3 with the ability to rotate under its own weight in the vertical plane and summing up under the fork 1. 1 Cp f-ly, 5 ill.

The invention relates to machine tool unloading devices, in particular, for unloading technological machine containers from perforated material with metal waste, working in a liquid, oil-cooling medium with limited access to the container, and can be used for unloading transport tanks in automatic lines of mechanical engineering, as well as in other fields of industry.

The purpose of the invention is to simplify the design.

Figure 1 shows a device for unloading containers, general; 2 is a kinematic diagram of the device; on fig.Z - floating 1st clamp, section, on figure 4 - the limiter of rotation of the pitchfork with the container; on fig.Z - ratchet mechanism.

The device contains forks 1 fixed with its own vertical parts with a large bearing area, on which the container 3c is fixed with the help of floating pin 2 and fixed on its side walls with its ends with the possibility of turning under its own weight in the vertical plane and leading under the forks of the IU frame. different handle 4.

The container is placed in a trough 3 for draining the liquid.

The forks are fixed on the shaft 6, mounted in the upper part of the uprights 7, with the possibility of turning a drive around its own axis, including a gear wheel 8 with a ratchet box 9, and a doggie 10 with a spring 11 is attached to the rack 7. wheel 8 is stationary gear wheel 12, which are in contact with gears 13, fixedly connected with gears 14. Gears 13 and 14 have the same number of teeth and are located on rollers 15 installed in water

la 16. At the second end of the carrier 16, the steering wheel 17 is fixed.

To avoid container self-tipping at a turning angle of more than 90, a protrusion 18 is rigidly fixed on the shaft 6, and a protrusion 19, which limits the rotation of the shaft 6 with forks, is fixed on the rack 7.

The device works as follows.

The container 3 (included in the process equipment) for unloading is rolled onto the fork 1 and fixed with the help of floating pins 2, having the ability to change its coordinates, and the handle 4, which due to its own weight is lowered under the fork 1.

Turning the handwheel 17 through a planetary gear, including gears 8, 12, 13 and 14, rollers 15 and the carrier 16 will rotate shaft 6. The magnitude of the angle of rotation depends on the number and difference of teeth of gear wheels 8 and 12. Shaft 6 with forks 1 rotates the container 3 around the axis of rotation by the angle required for lifting the load (metal shavings) out of the container {| L 3 into the workshop capacity 20.

A gear is represented by two gears 8 and 12 with a difference of teeth in one or two teeth and located coaxially with each other. Gears are in contact through three wide sheternes, each of which is represented by two rigidly connected gears 13 and 14 with the same number of teeth. One gear 12 fixedly mounted on the rack 7, the other gear 8 mounted on the shaft 6 of the fork 1.

To prevent a backward movement when the container 3 is rotated for unloading, a ratchet wheel 9 is attached to the gear wheel 8, and a dog 10 with a spring 11 is attached to the rack 7, thereby ensuring rotation only

in one direction. When rotated to the angle required for loading cargo from the container, the protrusion 18 will come into contact with the protrusion 19, thus limiting the angle of rotation.

After the container 3 has been unloaded into the mobile workshop tank 20, the dog 10 is disengaged and the container 3 returns to its original position. I

The proposed device is efficient in operation, it can be used for unloading containers with limited access, located in containers with liquid. The device allows the container to be withdrawn from the liquid medium with self-locking at the desired height for draining the liquid.
