Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention is intended to prevent spillage of rice in the shutter of the auxiliary discharge port of the grain tank mounted on the combine.

(B) Conventional technology Conventionally, in a combine grain tank, an auxiliary discharge port is provided in addition to a discharge device by a lower auger, a vertical auger, and a discharge auger.
Techniques such as Japanese Patent No. 43745, Japanese Utility Model Laid-Open No. 60-147240, and Japanese Utility Model Laid-Open No. 61-64247 are known.

Further, the conventional discharge port is constructed as shown in the drawing of FIG.

That is, the guide rail 22 'of the shutter 21' of the auxiliary discharge port is conventionally constituted by the set grain gutter 20 'on the guide rail 22' itself.
Since the lower part of 2'is not opened to the grain trough 20 ', the paddy was spilled downward when the shutter 21' was pushed.

(C) Problems to be solved by the invention The purpose of the present invention is to remove the paddy from the auxiliary discharge port between the shutter for closing the auxiliary discharge port and the guide groove formed by the guide rail. When the shutter is closed for the last time, the paddy in the guide groove is pushed downward to generate paddy spills, or the lower end of the guide rail is closed, so There was a problem that the paddy was bitten and crushed, and the shutter could not be shielded.

The present invention solves the problem.

(D) Means for Solving the Problems The object of the present invention is as described above, and the configuration for achieving the object will be described below.

At the shutter 21 portion of the discharge port 1b provided on the slanted grain surface 1a of the Glen tank 1, a guide rail 22 of the shutter 21 is attached to the outer surface of the slanted grain surface 1a in the vertical direction, and the lower end of the guide rail 22 is attached. The bottom of the grain trough 20 is arranged in an open state, and below the guide rail 22, a gap through which paddy can pass is formed.

(E) Embodiment The purpose and construction of the present invention are as described above, and the construction and operation of the embodiment shown in the accompanying drawings will be described below.

Figure 1 is a side view of a combine tank equipped with a Glen tank,
FIG. 2 is a front view of the threshing device D and the grain tank 1, FIG. 3 is a front perspective view of the auxiliary discharge port portion, FIG. 4 is a front sectional view of the auxiliary discharge portion, and FIG. is there.

In FIG. 1, the overall structure will be described. A V belt is wound around an auger drive pulley 9 from an engine output pulley 10 in an engine room equipped with a combine to transmit power to the lower auger 4 of the Glen tank 1.

The paddy collected by the lower auger 4 is fried by the vertical auger 3, inherited by the discharge auger 5, and discharged by the discharge auger 5 to a carrier such as a carrier or a truck.

The Glen tank 1 has a front end that can be pivoted largely to the side in order to facilitate the inspection of the drive device of each part arranged between the Glen tank 1 and the threshing device D, and the center of the pivot is vertical. Auger 3 is also used. The pivot tube 8 constitutes a support portion for supporting the rotation of the Glen tank 1. The lower part is supported by the pivots of the lower auger 4 and the vertical auger 3.

Further, the discharge auger 5 can be rotated right and left, and the left and right rotating device of the discharge auger 5 is constituted by a right and left rotating bevel gear 7 fixedly mounted on the vertical auger 3. Further, the discharge auger 5 can also be rotated up and down, and as a device that rotates up and down, a vertical rotation cylinder 6 is arranged in the vicinity of the joint between the vertical auger 3 and the discharge auger 5.

Further, rollers 14 and 14 which rotate on the machine body frame 15 are arranged as a support device when the front end of the Glen tank 1 rotates about the vertical auger 3.

In addition, the outer side of the Glen tank 1 is vertically rotated and projected,
An increasing tank 2 for increasing the capacity of the Glen tank 1 is arranged so as to be housed in a protruding manner.

In the overall configuration as described above, the present invention provides an auxiliary discharge port on the inclined grain surface 1a below the Glen tank 1.

The auxiliary discharge port is composed of a guide rail 22, a shutter 21, a grain trough 20, and bag receiving rods 23 and 23.

In FIG. 2, from the first conveyor 13 of the threshing device D,
The paddy after threshing selection is inherited by the fried grain cylinder 11, and the fried grain cylinder 1
It is fried by No. 1 and put from the upper part of the Glen tank 1.

The auxiliary discharge port of the present invention is disposed on the outer inclined grain surface 1a of the inclined grain surface that collects paddy on the lower auger 4 below the Glen tank 1.

Even though there are the lower auger 4, the vertical auger 3, and the discharge auger 5, the reason why the auxiliary discharge port is provided is
There is a high possibility that the paddy will be damaged while it is being carried out by the book auger, and the damaged paddy has a poor germination rate, so it cannot be used as seed paddy. Take out.

Also, lower auger 4, vertical auger 3 and discharge auger 5
Even when a failure occurs in the pad, it is also used when the paddy inside the grain tank 1 is temporarily discharged by using the auxiliary discharge port.

The structure of the essential part of the present invention will be described based on the structures of FIGS. 3, 4, and 5.

The outlet 1b is opened in the slanted grain surface 1a. An insertion plate type shutter 21 is arranged so that it can be inserted from above in order to switch the discharge port 1b between opening and blocking.

The guide rails 22 are arranged at the front and rear positions in order to form a guide groove for guiding the vertical movement of the shutter 21.

Conventionally, the lower end of the guide rail 22 is closed,
It was open to the outside of the grain shed 20. Therefore, when the shutter 21 in the opened state is closed, the paddy sandwiched in the guide groove is pushed downward to be spilled or crushed in the closed guide rail 22.

In order to eliminate such inconvenience, the present invention has a guide groove in which the lower end of the guide rail 22 is opened so that the paddy can fall, as shown in the embodiment of FIG. Further, since it is possible that the paddy in the guide groove overflows, the grain trough 20 is arranged below the open portion of the guide groove so that the paddy may overflow.

The original purpose of the flow grain trough 20 is to guide the paddy carried out from the discharge port 1b, and to introduce the paddy into the paddy bags arranged by being hooked by the front and rear bag receiving rods 23, 23. However, in addition to the original role, in the present invention, it also has a role of receiving the paddy pushed out from the opening at the lower end of the guide rail 22 forming the guide groove of the shutter 21 and guiding it to the paddy bag. .

(F) Effect of the Invention Since the present invention is configured as described above, it has the following effects.

Firstly, it is possible to smoothly open and close the shutter 21 without the paddy being caught in the guide groove formed by the guide rail 22 and the shutter 21 not being closed.

Secondly, the paddy does not spill downward from between the slanted grain surface 1a of the Glen tank 1 and the guide rail 22, and the paddy bag can receive all the paddy.
