Abstract

The invention relates to agricultural machinery, can be used in the construction of the bins of combine harvesters and provides increased reliability and accelerated the process of unloading grain from the bunker. The bunker is made with inclined side walls 3, contains a loading device, the lower unloading screw 6 and a visor located above it, made of sections 7, 8 spaced apart by height. The length of each section is half the size of the bunker along the axis of the screw 6. On the walls 3 there are intermittent directions 9, parallel to the axis of the screw 6. The edges of the sections 7, 8 are placed in the guides 9. To move the sections 7, 8 along the axis of the screw 6, actuators are provided in the form of hydraulic cylinders 10, 11, respectively. To unload the grain from the bunker, first, section 7 is pushed under hydraulic section 10 under section 8. After unloading one half of the bunker, the other is unloaded, for which section 7 is returned to its original position, and then section 8 is pulled by hydraulic cylinder 11 onto section 7. 4 sludge.

the sections 7, 8 carried along the height. The length of each section is half the size of the hopper along the axis of the screw 6. On the walls 3 there are intermittent guides 9 parallel to the axis of the screw 6. The edges of sections 7, 8 are placed in guides 9. For moving sections 7, 8 along the axis of the screw 6, there are actuators in the form of hydraulic cylinders 10,

11 respectively. To unload the grain from the bunker, section 7 is first pushed by hydraulic cylinder 10 under section 8. After unloading one half of the bunker, the other is unloaded, for which section 7 is returned to its initial position, and then section 8 is pulled by section 11 by hydraulic cylinder 11 onto section 7. 4 sludge.

The invention relates to agricultural machinery and can be used in the design of combine harvesters.

The purpose of the invention is to increase the reliability and accelerate the process of unloading grain from the bunker.

FIG. 1 schematically shows the proposed bunker, side view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 — node I in FIG. 3

The combine harvester includes a housing 1 having a bottom 2 with inclined side walls 3 interconnected at the bottom through a radial trench 4, a loading device 5, a lower unloading screw 6 located in the radial trench 4, and also a visor located above the unloading schneck b and made of two separated by height sections 7 and 8, the edges of which are placed in guides 9 mounted on side walls 3. The guides 9 are parallel to the axis of the screw 6. The length of each section 7 and 8 is half the size of the hopper along the axis of the screw 6. For remescheni sections 7 and 8 are provided along this axis drives made in the form of hydraulic cylinders 10 and 11, respectively, which are connected to hydraulic harvester (not shown). In order that the guides 9 do not interfere with the flow of grain to the unloading auger 6, the inclined walls 3 are made with steps 12, and the guides 9 are mounted on the soles of the steps 12. In addition, the guides 9 can be made intermittent in the direction of the axis of the screw 6 .

The bunker combine harvester works as follows.

During the operation of the combine, i.e. when filling the hopper, the unloading auger 6 is completely blocked by sections 7 and 8 of the visor. At that, section 7 is moved to the right up to the end of the bunker (Fig. 1), and section 8 is moved to the left until the end of the bunker, therefore the unloading screw 6 is isolated from the incoming grain mass. In this case, the pressure of the grain is perceived by a visor. Before starting the unloading of grain from the bunker, f unloading screw 6 is turned on, after which, using the hydraulic cylinder 10, the unloading jaw b is opened gradually as the grain arrives by pushing the lower section 7 of the visor under the upper section 8. Unloading one (first) half of the bunker The 0 7 is moved back to the end of the bunker and the hydraulic cylinder 11 begins to move the upper section 8 to the other side of the bunker, i.e., gradually, as the grain arrives, the unloading auger b is opened from the second end by pushing the upper section 8 over the bottom It section 7.

In the proposed bunker, gradually (as the grain arrives at the discharge auger), the last Q opens it from one end and from the other end. Such dosing of grain to the unloading auger during the unloading of the bunker eliminates the formation of grain arches above the aisle to the auger and clogging of the aisle with grain.

 Due to the implementation, the guides of the lower 9 intermittent sections 7 and 8 in the process of their movement push the grain out of the grooves of the guides 9 into the groove 4, which is nominal. Offered hopper design

0 from the grooves of the guides 9 into the chute 4, which prevents the guiding of the guides 9 with grain. The proposed hopper design allows for cleaning of the wad at full loading of the hopper, as well as in areas of high humidity.
