Description

[Detailed Description of the Invention] The present invention relates to a threshing machine for a combine harvester, etc., in which the rear side plate forming a handling chamber and its support structure are improved.

By the way, in this type of threshing machine, a handling chamber is provided in the upper part of the front part of the machine body, and the handling barrel is pivoted between the front outer side plate of the machine body that constitutes this chamber and the rear side plate of the machine body, and the By forming a grain culm supply port on the outer side plate and a straw removal port on the rear side plate, the grain culm supplied to the chamber by the feed chain is threshed by the above-mentioned handling cylinder, and the grain culm is threshed by the above-mentioned handling cylinder. The waste straw is carried out to the waste straw processing section at the rear of the machine. However, the straw discharge port in the rear side plate of the handling chamber is usually formed by cutting in a U-shape from the side of the side plate on the feed chain side. If the waste straw is long, the end on the ear side will hit the back of the outlet, preventing the smooth flow of the waste straw and causing a blockage in the back. Since the swing sorting plate provided must be located further below the lower side of the rear side plate, there is a drawback that the overall height of the aircraft body increases. Therefore, as shown in Japanese Utility Model Application Publication No. 55-37326 (Figures 1 and 2), the rear side plate of the handling room was made only in the upper part of the straw removal port, and the straw removal outlet spanned the entire width of the machine. There are some machines that are designed to be opened to prevent clogging at the back of the delivery port and to lower the overall height of the machine by allowing the swinging sorting plate to approach the handling barrel. The end of the rear plate on the feed chain side is separated from the outer plate of the fuselage, resulting in a so-called cantilevered state. Therefore, the upper and lower ends of the handling torso, whose rear end is pivotally supported by the rear plate, The position in the direction becomes unstable, and the clearance between the handling cylinder and the receiving net stretched on the bottom of the handling room is not constant, causing problems such as the handling teeth and the receiving net coming into contact or leaving untreated items. It is.

This invention was developed in view of these circumstances, and by using the rear panel of the handling room only in the upper part of the straw removal port, it is possible to prevent clogging at the straw removal port and reduce the overall height of the machine. At the same time, the middle part of the lower side of the rear side plate is attached at both ends to each of the front and rear horizontal frames installed at the lower position of the receiving net between the outer plates and the rear upper position of the straw removal port. By supporting it on the connected horizontal L-shaped vertical frame, the instability of the position of the end of the feed chain side of the rear side plate is eliminated, and thereby the above-mentioned contact between the handling teeth and receiving net, or unhandled parts, etc. It is designed to prevent the harmful effects of

This will be explained below using an example shown in the figure.
1 is the body of the threshing machine, 2 is a handling room provided above the front of the machine, and the room contains the front outer plate 1a of the machine.
and a handling cylinder 4 whose front and rear ends are pivotally supported by the rear side plate 3 of the handling chamber.
A grain culm supply port 5 is formed in the front lower part of the chamber, and a straw discharge port 6 is formed in the rear lower part. Here, the rear side plate 3 of the handling room is only the upper part of the straw removal port 6, and the straw is removed from the lower side 3 of the plate.
The straw is removed from the straw processing section 8 by the guide plate 7.
It is designed to be transported to Reference numeral 9 denotes a receiving net stretched over the lower surface of the handling chamber, and 10 denotes a sorting room provided below the net, which includes a swinging sorting plate 11 at the top, a winnower 12 at the front, and a first screw 13 at the bottom. , a second screw 14 is provided, and the grains, straw waste, etc. that are dropped from the handling chamber 2 through the receiving net 9 into the sorting chamber are sorted by the action of the rocking plate 11 and the sorting wind by the winnower 12, The first thing is Ichiban Screw 1
3, the second grain is carried out of the machine and stored in a paddy bag, and the second grain is supplied to the processing chamber 15 shown in FIG. 2 by the second screw 14 and a thrower (not shown) to be reprocessed. Suction blower 1 removes debris.
6 to be discharged outside the machine.
Reference numerals 17 indicate the left and right outer plates 1b of the machine body as positions behind the straw removal port 6 where there is no hindrance to the passage of straw;
A rear horizontal frame 18 is installed between the left and right outer plates 1b and 1c, and 18 is a front horizontal frame installed between the left and right outer plates 1b and 1c at a position below the receiving net 9 near the rear of the handling room. They are provided at the front and rear of the rear side plate 3 so as to sandwich the rear side plate 3, and 19
is a vertical frame having a horizontal L-shape and supported at both ends in the middle of the horizontal frames 17 and 18, and is connected to the rear side plate 3 of the handling room.
An intermediate portion of the lower side 3a is supported on the vertical frame.

According to the above configuration, the rear side plate 3 forming the handling chamber 2 is located only in the upper part of the straw removal port 6 provided at the rear of the chamber, and the straw removal port is opened over the entire width of the machine body 1. Therefore, the waste straw does not get clogged at the outlet, and the oscillating sorting plate 11 is not connected to the handling drum 4 or the receiving net 9 than when the outlet is formed by cutting the rear side plate from the side. They are brought close together. However, the rear side plate 3 of the handling room is fixed to the right outer plate 1c of the machine body at the side 3b on the side opposite to the feed chain, and the side 3c on the feed chain side is separated from the left outer plate 1b of the machine body. However, horizontal frames 17 and 18 are constructed between the two outer panels 1b and 1c, and a horizontal L-shaped vertical frame 19 with both ends connected to the two horizontal frames is provided. Since the middle part of the lower side 3a is supported, the position of the feed chain side side 3c of the rear plate becomes unstable in the vertical direction as shown by arrow A-A in FIG. As a result, the clearance between the handling cylinder 4, which is pivotally supported by the rear plate, and the receiving net 9 is maintained constant, and there is no possibility of unhandled items due to contact between the handling teeth 4a and the receiving net, or separation of both. will be prevented.

As described above, the present invention provides only the upper part of the straw removal port provided at the rear lower part of the rear side plate of the handling chamber that pivotally supports the rear end of the handling cylinder, and the lower middle part of the rear side plate. , both ends of which were connected to the front and rear horizontal frames installed between the left and right side plates of the machine, below the receiving net at the front and rear positions of the rear side plate, and at each position above the rear of the straw discharge port. Since it is supported by an L-shaped vertical frame, it is possible to prevent clogging at the straw discharge port and reduce the overall height of the machine. Rather than being done in a cantilevered manner,
By being supported vertically below the rear plate to which force is applied, it becomes extremely strong and eliminates the instability of the vertical position of the handling cylinder whose rear end is pivotally supported by the plate. This maintains a constant clearance between the handling cylinder and the receiving net, and has the effect of preventing problems such as contact between the handling teeth and the receiving net, or unhandled parts.
