Description

The inventive utility model relates to agricultural machinery, in particular, to the unloading devices of the bins of combine harvesters, and more specifically, to mechanisms for adjusting the position of the shutter of the casing of the unloading screws located inside the bunker.

A device is known for manually adjusting the gap between the shutters of the auger casing and the bottom of the hopper of the combine by loosening the nuts on the flaps inside the hopper (Operating Instructions for the TORUM-740 combine - PCM-181 IE, edition of 17.12.2012, paragraph 6.4, figure 6.32). To carry out this operation, the operator needs to go down to the hopper, unscrew two nuts on each of the four shutters of the auger casing, move the shutters to the desired position and tighten the nuts. This adjustment must be performed on the four shutters, and if two screws are installed in the hopper, the time for adjusting the shutters is doubled.

Closest to the claimed utility model is a device for adjusting the position of the shutters using a torsion bar mounted on the casing of the auger screw on its outer side, which is used on the Yenisei KZS-950 combine harvester (Electronic catalog of spare parts for the Yenisei KZZ-950 combine. - Equipment working combine "Yenisei KZS-950. - Hopper. - Screw casing with shutters (website http://www.avtoall.ru). The principle of operation of the prototype device is that when you turn the adjustment lever manually installed on the outside b nkera and connected to the torsion bar, the damper rise upwards, with a clearance between the bottom of the hopper and the flaps increases, and by turning the lever in the opposite direction of the flap down and the gap decreases.

The disadvantages of the described device are the inability to raise the shutters when the hopper is full to increase the feed of grain to the screws; the need to seal the torsion bar at its entrance to the hopper to prevent spillage of the grain mass; possible grain losses due to the ingress of grain mass in the gap between the casing and the shutters; high metal production of torsion bar; an even greater increase in the complexity of the process of adjusting the position of the dampers in the twin-screw hopper by adjusting the dampers on each screw individually.

The objective of the proposed technical solution is to simplify the process of servicing the hopper by reducing its complexity; reduction of grain losses during unloading from the hopper into the unloading auger; reduction of metal consumption for the manufacture of structural elements of the hopper discharge device.

The technical result is achieved due to the fact that into the unloading device of the hopper containing the casing of the auger of the hopper, dampers, the slats that move the dampers, the axis of fastening of the slats connected to the brackets of the dampers, and the lever for manually adjusting the gap between the dampers of the casing of the auger and the bottom of the bunker of the combine are introduced bracket with holes and a latch, inclined slots are made on the flaps, and the lever for manual adjustment of the gap between the flaps of the auger casing and the bottom of the combine hopper is made as a lever for moving traction, while the flaps are sha they are pivotally connected to the thrust, the axes at one end are rigidly connected to the thrust, and the other ends are pivotally connected on one side to the slats, which on the other hand are pivotally connected to the flaps, while the flaps and the thrust are installed inside the casing, and the flaps are moved by strips in the direction of the inclined grooves on the dampers; the clamp fixes the positions of the lever during its discrete movements with a certain step through the holes in the bracket.

The claimed technical solution is illustrated by the drawings:

- FIG. 1 is a General view of the base of the hopper and the location of the shrouds of the screw;

- FIG. 2 is a diagram of a device;

- FIG. 3 is a structural drawing of a General view of the lever mechanism for adjusting the valves and the place of its installation;

- FIG. 4 - FIG. 3, section AA;

- FIG. 5 - FIG. 3, section BB;

- FIG. 6 - FIG. 5, view B;

- FIG. 7 - FIG. 4, section GG.

The inventive utility model consists of the following structural elements (Fig. 1-7): 1 - lever; 2, 3 - shutters; 4 - hinge; 5 - thrust; 6 - support; 7 - thrust; 8 - auger casing; 9 - level; 10 - washer; 11 - axis; 12 - lever support; 13 - an arm; 14 - an arm; 15 - latch; 16 - cotter pin; 17 - finger; 18 - bottom of the hopper.

The flaps 2 and 3 are mounted on the casing of the screw 8 and secured with the help of the axis 11, the washer 10 and the cotter pin 16. The slats 9 are mounted on the flaps 2 and 3 on the one hand and the thrust 7 on the other side and are fixed with the washers 10 and the cotter pin 16, thrust 5 is installed in the rod 7 through a threaded connection, supports 6 in the amount of 4 pcs. mounted on the auger casing and hold the rod 7. The lever 1 is mounted outside the hopper on the brackets 14 and mounted in the sliding bearing 12 with polyamide inserts and connected by a finger 17 to the rod 5 through the hinge 4. The bracket 13 is used to fix the lever 1 in various operating positions with a certain step.

The inventive device operates as follows (Fig. 1-7). When acting on the lever 1 with a hand from itself, the lever 1 rotates in the supports 12, while the movement of the lever 1 is transmitted to the hinge 4, and from it to the rods 5, 7. In turn, the rod 7 moves the strap 9 fixed on it, which moves , pulls the shutters 2, 3 along the inclined guide grooves (not shown in the figures) through which the axis 11 is installed. At the same time, the shutters 2, 3 rise up, and the gap between the shutters 2, 3 and the bottom of the hopper 18 increases. The lever 1 is fixed by the latch 15 through the hole in the lever 1 and the bracket 13 with a given pitch (14-15 mm). When acting on the lever 1 with a hand on itself, the shutters 2, 3 are lowered down, and the gap between the bottom of the hopper 18 and the shutters 2, 3 also decreases with a given step.

The application of the claimed utility model allows to reduce the complexity of the process of adjusting the mechanism of unloading grain from the hopper when transporting it to the unloading screw and grain loss when transporting it from the hopper to the unloading screw, providing the possibility of simultaneous adjustment of the position of the shutters in the twin-screw hopper, eliminating the need to seal the holes in the place of entry of the draft into the hopper, increase the supply of grain mass to the screws when the hopper is full and reduce the metal consumption for the manufacture of structural elements ntov unloading hopper device.
