Description

The invention relates to agriculture and can be used at fruit and vegetable enterprises, at the potato and forestry centers of collective and state farms.

A device for loading bulk materials is known, which comprises a hopper with a valve and an elastic chute with a lifting drive.

The disadvantage of this device is the damageability of the material due to its fall along the elastic flow.

The closest in technical terms to the claimed is a device comprising a hopper, a receiving hinge, an elastic chute with a lifting drive, a bolt and a two-jaw slide with a drive system.

A disadvantage of the known device is the damageability of the material (for example, potato tubers) due to a fall from the valve to the bottom of the double jaw seal, as well as during the advance along the walls of the elastic chute, folded in accordion.

The purpose of the invention is to reduce the damage of items when loading

The goal is achieved by the fact that in the device for loading easily damaged objects into a container containing a receiving neck, an elastic chute extended downwards with a two-maxillary shutter at the bottom and a drive, the chute is bandaged outside by stiffeners with radially arranged curved brackets. drive gears, the ends of which are attached to the stops mounted on the jaw of the bolt. The jaws of the shutter are made in the shape of a quarter sphere each. The shutter is provided with a latch and each jaw of the shutter has a lever, one of which is spring-loaded. There are stops for &

jaw openings, and load level sensors electrically connected to the drive are installed inside it.

FIG. 1 shows a device for loading easily damaged objects into a container; figure 2 - termination; FIG. 3 shows load level sensors; figure 4 - the retaining ring with eyelets; Figures 5-7 show fragments of the device explaining its operation.

The device for loading containers 1 consists of an elastic chute 2 fixed on the receiving neck 3 and stiffened by rings 4 which are sequentially fixed on the outside. The heat pipe is made expanding downwards, the bottom of the chute 2 is made in the form of a shutter consisting of the jaws 5 and 6 with the opening and closing mechanism. The jaws are made in the form of a quarter sphere each and are fixed in the closed position by a spring-loaded latch 7, on levers 8 and 9 by means of a spring 10 and in the closed position by springs 11 and 12. The opening and closing mechanism of the shutter also includes adjustable stops 13-15. On the intermediate links in heat 2, the retaining rings 4 are equipped with radially positioned brackets 16c with eyelets on the ends 17. On the jaw x 5 and 6, stops 18 and 19 are installed with flexible pipes 20 and 21 embedded in them that pass through the eyelets 17. With the lifting upstream (assembled position), the brackets 16 are located tightly to each other, the lugs are placed one above the other along common verticals represented by flexible rods 20 and 21 of the mechanism of raising and lowering the estrus. Flexible rods 20 and 21 through tensioning devices 22 and 23, equipped with switches 24 and 25, are wound on electric-driven drums 26 and 27. Objects 28 are fed to a belt conveyor 29 located above the receiving port 3. At the receiving port 3, the upper and lower sensors 30 and 31 of the loading level are located using the bracket 32 and the reflector 33.

The load level sensors 30 and 31 are equipped with switches 34 and 35 and are electrically connected to the drive through switches 24 and 25.

The device works as follows.

In the absence of easily damaged objects 28, elastic estrus 2 is in the upper position in the state assembled in the corrugations (Fig. 4). In this case, the levers 8 and 9 abut against the stops 14 and 15, and the jaws of the bottom 5 and 6 are closed and held in the closed state by the latch 7 (Fig. 2). By entering through the belt conveyor 29, easily damaged objects 28 roll down from the elastic reflector 33 and fill the chute 2 prior to contact with the load level sensor 30. Switch 34 commands

Down on the drive of the drums 26 and 27, which coil the flexible rods 20 and 21 through the tensioning devices 22 and 23, lowering the chute 2 down until the contact of easily damaged objects with the sensor 30 stops. After the chute stops, the level of the chute loading will rise again until it reaches sensor 30. 8 moment of contact, sensor 30 sends a Down command to the drive. Cycle

5 is repeated until the chute 2 is filled with easily repositioned objects.

After fully filling the chute 2, the lever 8 of the jaw 5 is pressed: the stop 13, the latch 7, the jaw open, and 5 and b are opened by the action of the springs 11 and .12, and the easily damaged objects 28 are moved into the container 1. The tension of the flexible t g 20 and 21 weakens, tension levers

5 devices 22 and 23, under the action of springs, rotate and close the contacts of switches 24 and 25. In the filling mode, 2 contacts of switches 24 and 25 are open and the sensor 30 when in contact with

0 easily damaged items gives the drive a Down command, in the absence of a contact-command Stop. In tare 1 mode, the switch contacts are closed, and the sensor 30 is in contact with

5 easily damaged objects sends the command Up to the drive, if there is no contact, the command Stop.

After the bottom of the chute is opened, the objects are moved to the container, and their level in the chute is lowered. As the gap between the chute hole and the bulk of the damaged objects in the container shrinks, the objects move from the chute

5 into the gar slows down and then stops. As a consequence, the level of loading of objects in estrus will increase until then. until it reaches sensor 30. At the moment of material with sensor 30, switch 34 of sensor 30 will issue an Up command to the drive. In this case, the flexible rods 20 and 21 will be wound on the drums 26 and 27. lift the lower ring of stiffness upwards through the stops 13 and 19, between the hole

5 heat and bulk material in the container, a gap is formed through which easily damaged objects will move from the heat to the container. The cycle repeats until the levers 8 and 9 reach the stops 14 and 15. The limit switch turns off the drive.

The bottom load level sensor 31 operates as follows. In the heat 2 mode, when the contacts of the switches 24 and 25 are open, the sensor 31 is switched off. In tare filling mode 1, in the state of contact with easily-damaged objects, the sensor 31 does not send signals to the actuator. When there is no contact, i.e. The level of estrus filling is below the location of the sensor 31, and the sensor 31 sends the Down command to the drive. In the process, this happens as follows. When, at any level of filling of the container 1, the process of unloading begins, the removal of items from the container may be faster than their arrival. At the same time, the level of loading of estrus with easily damaged items will decrease. Sensor 31 will come out of contact with easily damaged objects and will issue a Down command to the drive. By lowering the chute, the gap between the chute hole and the bulk of objects in the container decreases, moving from the chute to the container slows down, and then stops, as a result of which the loading level of the chute will be at the height of sensor 31 After the unloading of objects from the container stops will go down at the height of sensor 30.

The technical and economic advantages of the invention are that the damageability of the material in the proposed technical solution is reduced by reducing the height of the objects falling from the conveyor to the bottom of the estrus and, moreover, due to

along the smooth walls of the chute, the material does not suffer any damage that occurs when moving along the walls of the chute, in the shape of an accordion.
