Description

The invention relates to agricultural machinery and can be used in the construction of self-propelled tracked combine harvesters.

Known self-propelled rice and grain harvester "Yenisei-1200P" containing a header with an inclined chamber, a double-drum threshing device with an intermediate beater, a separating grate and a jack beater, cleaning the thresher with straw walker keys, a fan, a shaking board, a sieve mill, a grain and spike elevator with , a hopper for collecting grain with an unloading device located on the roof of the thresher, a control panel with a cabin and a motor unit located at the top on the roof of the thresher.

The disadvantage of this combine is:

1. Lack of a device for determining the amount of grain threshed and unloaded from the hopper of the combine.

2. An increased percentage of grain damage during unloading due to the presence of leveling and horizontal augers in the hopper design.

Also known is the “Vector” combine harvester manufactured by “Rostselmash”, which contains a reaper with an inclined chamber, a single-drum threshing device, a chipper, a threshing machine with straw walker keys, a fan, a shaking board, a sieve mill, a grain and spike elevator, a grain collection hopper with an unloading a device located on the roof of the thresher, a control panel with a cabin and a motor unit located at the top on the roof of the thresher.

The disadvantage of this combine is also:

1. Lack of a device for determining the amount of grain threshed and unloaded from the hopper of the combine.

2. An increased percentage of grain damage during unloading due to the presence of a horizontal screw in the hopper.

The purpose of the invention:

1. Determine the mass of threshed and unloaded grain from the hopper of the combine.

2. Reduce the percentage of grain damage during unloading.

This goal is achieved by the fact that the grain collection hopper is mounted on the caterpillar truck frame separately from the unloading device and mounted on strain gauges, the strain gauge of which with the exponential device is displayed on the control panel, while the grain collector in the lower part has a hatch with a device for opening it and closing, for example, in the form of a damper controlled by a hydraulic cylinder, and the unloading device has a loading tank, which is located under the grain collection hopper opposite the hatch and does not come into contact with him.

The section of the hatch in the horizontal plane and the outer contour of the inlet of the loading container are predominantly rectangular and similar to each other, while the projection of the section of the hatch onto the horizontal plane is smaller than the outer contour of the loading container.

Thus, the inventive self-propelled tracked combine harvester meets the criterion of "Novelty."

Signs that distinguish the claimed technical solution from the prototype, in other technical solutions of this technical field are not identified, which allows us to conclude that the inventive self-propelled tracked combine harvester meets the criterion of "significant differences".

Figure 1 shows the proposed combine self-propelled tracked grain harvester, General view (diagram), left view; figure 2 is a view a of figure 1.

The self-propelled caterpillar combine harvester contains a header 1 with an inclined chamber 2, a double-drum threshing device 3 with concave 4, two intermediate beaters 5, a separating grate 6 and a chipping beater 7, cleaning the thresher with the keys of a straw walker 8, fan 9, shaking board 10, sieve mill 11 with a sloping board 12, an elevator 13 for transporting under-thinned spikelets, a hopper 14 for collecting grain mounted on the frame 15 of the caterpillar 16 separately from the unloading device 17. The hopper 14 for collecting grain is installed on and strain gauges 18, the strain gauge 19 of which with the indicating device 20 is displayed on the control panel 21, while the hopper 14 for collecting grain in the lower part has a hatch 22 with a device for opening and closing it, for example, in the form of a shutter 23 controlled by a hydraulic cylinder ( not shown), and the unloading device 17 has a loading tank 24, which is located under the hopper 14 for collecting grain opposite the hatch 22 and is not in contact with it, while the cross section of the hatch 22 in the horizontal plane and the outer contour of the inlet of the boot th container 24 are preferably rectangular and similar to each other, the projection of the hatch section 22 in the horizontal plane less than the outer contour of the storage container 24; a harvester 25, a straw chopper-spreader 26, a control panel 21 is located in the cab 27, and all the working bodies of the combine are driven by a motor unit 28 mounted on the frame 15 of the tracked trolley 16.

When the combine is moving, the header 1 cuts off the stalks of the grain crop and feeds it into an inclined chamber 2, which transports the grain mass to a double-drum threshing device 3 with concave 4, two intermediate beaters 5 and a separating grate 6. Here the grain mass is threshed.

The straw mass arrives at the pickup bit 7 and is sent to the keys of the straw walker 8, where it is freed from free grain, light impurities and fed to the straw chopper-spreader 26, which chopping the straw and spreading it evenly across the field.

Separated by threshing grain and fine impurities through concave 4 and the separating lattice 6 fall on the shaking board 10.

Due to the complex reciprocating movement of the shaking board 10, the heap moves in the direction of the sieves of the shaking board 10 and the sieve mill 11. With a fan 9, light impurities are blown out and sent to the scoop 25. which rakes them outside the thresher.

The grain separated from the heap falls through the sieve of the sieve mill 11 and through the pitched board 12 enters the hopper 14 for collecting grain, which is mounted on the frame 15 of the caterpillar 16 under the sieve mill 11 at the center of gravity of the combine.

Under-thinned spikelets that failed through the sieve of the shaking board 10 go to the elevator 13 for transporting them to the moulder (not shown in FIG.) Or to the double-drum threshing device 3 for re-threshing. The drive of the working bodies of the harvester is carried out using a motor unit 28 mounted on the frame 15 of the tracked trolley 16.

The combine is controlled from the cab 27 using the control panel 21, which displays the strain gauge 19 with a display device 20.

When filling the hopper 14 for collecting grain, the shutter 23 of the hatch 22 is closed. To unload grain, it is necessary to turn on the unloading device 17 and open the shutter 23 of the hatch 22. Grain under its own weight falls into the loading tank 24, then the unloading device 17 is sent to the vehicle body (not shown in Fig.). Since the cross section of the hatch 22 in the horizontal plane and the outer contour of the inlet of the loading tank 24 are predominantly rectangular in shape and similar to each other, while the projection of the cross section of the hatch 22 onto the horizontal plane is smaller than the outer contour of the loading tank 24, the possibility of spilling grain from the loading tank 24 is excluded.

Due to the fact that the grain collection hopper 14 is mounted on the frame 15 of the tracked trolley 16 separately from the unloading device 17 and mounted on the load cells 18, the strain gauge 19 of which with the display device 20 is displayed on the control panel 21, the display device 20 will record all changes, associated with filling the hopper 14 with grain and unloading it, that is, determine the mass of grain located in the hopper 14 for collecting grain.

Using the proposed self-propelled tracked combine harvester will:

1. Determine the mass of threshed and unloaded grain from the hopper of the combine.

2. To reduce the percentage of grain damage during unloading due to the exclusion from the design of the hopper for collecting grain horizontal screw.
