Description

[Detailed Description of the Invention] <Industrial field of application> The present invention is a discharging device for beans that discharges and loads harvested and threshed beans into a vehicle with a high vehicle height (eg, dump truck, wagon, etc.). Regarding

<Problems to be solved with the prior art> Grains such as rice and wheat can be transferred from the threshing machine to a high-position carrier using a screw conveyor. Is widely used.

However, when beans are conveyed by a screw conveyor, the beans are cracked, and the number of defective beans increases.

On the other hand, Japanese Utility Model Publication No. 61-37239 proposes a moving thresher having a system for discharging grains without using a screw conveyor.

This thresher is a system that sets the discharge angle while moving up the grain tank, so when the tank is located at the bottom and the swing link angle is close to vertical (that is, if it is a small angle of about 10 degrees). ), The length of the link exerts the effect of a refilling rod, making it difficult to open the angle of the grain tank, and it becomes necessary for the worker to open the angle of the tank to a certain degree (for example, it is necessary to open it to about 45 degrees). It is inconvenient to work, and each time the worker opened the grain tank angle,
There is a problem that the work time becomes unnecessarily long.

The present invention has been made in view of these circumstances, and an object thereof is to provide a useful discharging device that is less likely to damage beans and that can efficiently perform discharging and loading work.

<Means for Solving Problems> Means to be taken by the present invention for solving the above problems is to provide a hopper vertically movable along a pair of left and right column frames in a machine frame, and lower a front side of the hopper. One end of the discharge member is rotatably pivotally attached to the discharge port opened to the upper side of the hopper at the lower end position of the hopper at the lower side of the hopper at the front side between the pair of left and right column frames. It is characterized in that a supporting rod is laterally installed at a position below the pivot portion of the discharging member at the upper limit position, and an outer surface of the bottom portion of the discharging member is always in contact with the supporting rod.

<Operation> When the hopper is at the lower limit position, the support rod abuts on the outer surface of the bottom of the discharge member above the pivotal portion of the discharge member,
Therefore, the discharge member is stored vertically and covers the discharge port of the hopper. Then, as the hopper moves upward, the height of the pivoting portion of the discharge member approaches the height of the support rod and eventually reverses.
Therefore, while the outer surface of the bottom of the discharging member is supported by the supporting rod, the discharging member is gradually tilted forward by its own weight about the pivotal portion, and when the hopper reaches the upper limit position, the pivotal portion is positioned above the supporting rod, An outer surface of the bottom of the discharge member is supported by the support rod to form a discharge passage that extends downward from the pivot portion toward the front side of the support rod.

An engaging shaft (5) projectingly provided on the inner end of the elongated engaging hole (10a) and the upper left and right ends of the shutter member (5).
b) and loosely engaged with each other, and each operating rod (1
The outer end of (0) is slightly extended from both the left and right sides of the hopper (2) so that when the discharge port (3) is closed, both operating rods (10) (1
(0) is provided in the shape of an inverted C. Then, in the process of upward movement of the hopper (2) from the lower limit position shown in the second illustration to the upper limit position shown in the third illustration, the above-mentioned respective operations are performed on the locking projections (11) provided on the upper parts of the left and right column frames (1a) respectively. The outer ends of the rods (10) are brought into contact with each other, and in conjunction with the movement of the hopper (2) raised to the upper limit position, as shown in FIG. 5, the operating rods () connected to the shutter member (5). The inner end portion of 10) pivots upward about each shaft attachment portion (10b), pushes up the shutter member (5) against the biasing force of the spring member (9), and the discharge port ( 3) is configured to be opened.

The discharge member (4) is formed in a gutter shape, a tubular body, etc., and both upper end portions of one end thereof are pivotally attached to the left and right side edge portions of the discharge port (3) on the front side of the hopper (2), and the pivotal attachment is performed. Department (4a)
It is provided so as to be rotatable forward around the center.

Further, on the front side between the pair of left and right column frames (1a) of the machine frame (1), above the pivotal portion (4a) of the discharge member (4) at the lower limit position of the hopper (2) and at the hopper ( At the upper limit position of 2), the supporting rod (8) is laid horizontally at a position below the pivotal portion (4a) of the discharge member (4),
