Abstract

The invention can be used in the design of combine harvesters, working with the collection of grain mass in the bunker, provides increased reliability of the process of unloading grain and reducing its injury. The bunker includes a housing 1 with inclined lower side and end 14 walls. In the housing 1 there is a loading device 3, a lower discharge screw 4 and housings 6, 7, which are offset in height relative to each other and located above the screw 4. The drive for moving the housings 6, 7 along the axis of the screw 4 has hydraulic cylinders 8, 9, rods 10, 11 which are connected to the covers 6, 7, respectively. For housings 6, 7, guides are provided, made in the form of a rod 5 mounted above the screw 4 under the housings 6, 7 and attached to the end walls 14. The volume of the hopper is divided into two parts 17, 18 by means of a partition 16. Grain is unloaded alternately from parts 17, 18. To do this, when the screw 4 is turned on, the grain is opened to its corresponding sections by alternately moving the housings 6, 7 by means of hydraulic cylinders 8, 9. The rod 5 does not prevent the grain from entering the screw 4. 2 Il.

Description

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 of the process of unloading grain and reduce its injury.

Figure 1 shows the combine harvester bin, the longitudinal section of Figure 2 is a section AA in Figure 1.

 The bunker of a combine harvester is contained in case 1, made with inclined lower side cTeHKaiviH, interconnected at the bottom via a radial trench 2. The bunker contains a loading device 3, the lower unloading screw 4, located in the radial trench 2, rails 5, parallel to the pin of the pin, 5, parallel to the axis of the pin, and 5. spaced apart housing 6, 7 located above unloading 4, and driving movement of cases 6, 7 along the axis of the screw 4, made in the form of hydraulic cylinders 8, 9, the working cavities of which are connected to the hydraulic system of the combine (not shown). The hydraulic cylinders 8.9 are placed in the bunker above the casings 1a 6, 7. The rods 10, 11 of the hydraulic cylinders 8, 9 are respectively connected to the casings 6, 7 through the rods 12, 13, while the rod ends are located outside the housing 1 o

The length of the covers 6, 7 should be such that small covers of the covers (for example, 0, 0.05 m) are obtained when one of them is moved to the right to the end of the bunker, and the second to the left to the end of the bunker. The casings 6, 7 are connected to the guides 5, which are made in the Biode rod, located under the casings 6, 7 above the screw 4 and attached to the end walls 14 of the bunker. The rod is equipped with movable couplings} 15 "which are rigidly connected to the housing 6, 7. The lower housing 6 is connected, for example, to two movable couplings 15 located at the ends of this housing, and the upper housing 1. one located at one end of the casing.

In addition, the combine harvester bin contains a partition 16 located in the middle of the bunker above the shells 6, 7 in a plane transverse to the axis of the unloading screw 4. The partition divides the bunker into two parts 17 and 18. The height of the partition

0

may be equal, for example, 1/2 - 2/3 of the height of the bunker.

The inclined side walls of the hopper are made with depressions parallel to the axis of the unloading screw 4, in which support strips 19 are placed for the edges of the housings 6, 7. The width and depth of the depressions are respectively equal to the width and thickness of the strips 19

The bunker combine harvester works as follows.

During combining, i.e. when filling the bunker, for example, with seed mass, the unloading screw 4 is completely blocked by covers cb 7. At the same time the casing 6 is moved to the right (Fig. 1) until the end of the bunker, and the casing 7 - to the left until the end of the bunker, therefore during the filling of the bunker the screw section 4, placed in the first part 17 of the bunker, is isolated from the incoming seed mass by the casing 6, and in the second part 18 of the bunker - by the casing 7. Petied start the unloading of the seed mass from the bunker include the unloading screw 4, after which the hydraulic cylinder 8 gradually , as the seed mass arrives, open the outgrowth. hydrochloric screw 4 in the first part 17 of the hopper through the lower impinger 6 under the top cover 7. After unloading the first portion

17 hoppers, the lower case 6 is moved back to the end of the bunker and the hydraulic cylinder 9 is filled; 1, the upper case 7 is moved, i.e. gradually, as the seed mass arrives, the unloading screw 4 is opened in the second half of the 18 bunker by pushing the upper case 7 over the lower case 6. After unloading the second part

18 bunker casing 7 is moved back to the end of the bunker and turn off the unloading auger 4.

Claims (1)

This bunker allows to increase the reliability of the grain unloading process, since The described arrangement of the guides made in the form of a rod does not lead to the formation of vaults of the grain (seed; -) mass and does not prevent its entry into the unloading auger. In addition, the reliability of moving the covers along the auger axis is improved, the damage to the seeds is reduced, since eliminated blockage of guides by the seed mass. Invention Formula Combine-combine hopper, comprising a housing with inclined lower side and end walls, as well as a loading device placed in the housing, an unloading auger,. Two located above the screw of the housing, displaced in height relative to each other, drive the movement of the skin along the axis of the sump and guides for casings, characterized in that, in order to increase the reliability of the grain unloading process and reduce its injury, the direction is made in the form of a rod mounted above the screw under the casings and attached to the end walls. nineteen 1B Phage.2
