Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for discharging residual grains from a threshing machine such as a combine harvester, and is capable of completely discharging residual grains with an extremely simple operation.

By the way, in this type of threshing machine that continuously processes grain from the harvested culm, sorting, and storing it, grains tend to remain at the bottom of the grain case and the first and second screw cases in the sorting room. When processing different types of grain with a single threshing machine, the previously processed grain may contaminate the next grain and cause a drop in grade, and when the threshing machine is stored for a long period of time, residual grains may This causes various harmful effects. On the other hand, conventionally, in order to discharge residual grains, an openable part was provided on the side wall of the fuselage on the side of the toumi and -2 second screw, or an openable part was provided on the side of the toumi case and one,
Although the bottom of the No. 2 screw case can be opened and closed, providing an openable part on the side wall of the fuselage reduces the strength of the fuselage. Since these were located at the bottom of the aircraft, it was extremely difficult to open and close them individually.

The present invention has been made in view of these circumstances, and includes mounting covers that can be opened and closed at the bottom of the tomi case and the first and second screw cases in the sorting room, and that each cover can be opened and closed via an interlocking mechanism. Operating members that open and close all at once are arranged at appropriate positions outside the machine body, so that residual grains can be discharged extremely easily simply by operating the members outside the machine body.

This will be explained below using the example shown in the figure. 1 is the body of the threshing machine, 2 is a handling room provided in the upper front part of the machine,
A handling cylinder 3 is housed in the chamber, and a receiving net 4 is stretched along the lower surface of the handling cylinder 3. Reference numeral 5 denotes a rocking plate disposed below the handling chamber 2, and 6 a sorting chamber disposed below it. A dust blower 10 is also installed at the rear of the aircraft.

Here, the bottom of each case 11, 12.13 of the above-mentioned top and first and second screws in the sorting chamber is opened over almost the entire width, and each opening is provided with hinges 14a, 15a, 15a on one side. Covers 14, 15 and 16, which can be opened and closed, are attached respectively.

Reference numeral 17 denotes an operating member that is swingably supported by a bracket 18 on the outside of the fuselage 1, and 19 an interlocking mechanism that interlocks this member with each of the above-mentioned covers.
a rod 21 held so as to be movable back and forth, and links 22, 2 whose ends are pivotally connected to the rod and each cover, respectively.
3.24, and a pin 21a is provided at the front end of the rod 21 and is engaged with a fork 17a at the end of the operating member 17.

According to the above configuration, the husks carried into the handling chamber 2 by a feed chain (not shown) are threshed in the chamber by the rotation of the handling drum 3, and the threshed grains are sent to the receiving net 4 and shaker. They are dropped into a sorting chamber 6 via a moving plate 5, and are sorted in the chamber by the sorting wind of the rice grains 7. - The aromatics are transported outside the machine by the first screw 8 and stored in a paddy bag (not shown). The second material that needs to be reprocessed is returned to the handling chamber 2 by a second screw 9 and a thrower (not shown), and straw waste and the like are discharged from the machine by a blower 10. However, at the end of the work, each case 11.12.1 of the above-mentioned toumi and No. 1 and No. 2 screws
In this case, if the operating member 17 installed outside the machine is swung from the position shown by the solid line to the position shown by the chain line in the figure, the part can be removed. By moving the rod 21 engaged with the case forward, the covers 14, 15, and 16 attached to the bottom of each case are opened all at once as shown by the chain lines through the links 22, 23, and 24. As a result, the grains, straw, etc. remaining at the bottom of each case are discharged downward, and the inside of the case is cleaned. Furthermore, if the operating member 17 is returned from the position shown by the chain line in the figure to the position shown by the solid line after discharging the residue or before starting work, each case 11, 12
．． The bottom of 13 is closed by cover 14, 15, 16 and is ready for operation.

As described above, the residual grain discharge device in the threshing machine of the present invention opens the bottoms of the grain case and -1 No. 2 screw case in the sorting room and attaches covers that can be opened and closed, respectively, and each By arranging the operating members that open and close the covers all at once at appropriate positions outside the machine, all you have to do is operate the above members when the work is finished, and since these members are located outside the machine, it is extremely easy to do so. It is now possible to discharge residual grains from the bottom of each case, which reduces the possibility of degrading the grade due to the contamination of different types of grains, or causing various problems caused by residual grains when the threshing machine is stored for a long period of time. This has the effect of preventing harmful effects, and in particular, according to the present invention, there is no reduction in the strength of the fuselage body when opening the side wall of the fuselage body, and there is an advantage that workability is excellent.

Claims (1)

[Claims] (1) The bottom of the Toumi case and the No. 1 and No. 2 screw cases are opened over almost the entire width, and a cover is attached to each opening so that it can be opened and closed, and an operating member is provided that opens and closes each cover at the same time via an interlocking mechanism. A device for discharging residual grains in a threshing machine, characterized in that it is disposed at an appropriate position outside the machine body.
