Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a grain recovery device which is used by being mounted on a combine or the like in which a horizontal feed screw for discharging a stored material is provided at the bottom of a Glen tank.

[Conventional technology]

In this type of grain collecting apparatus, conventionally, the lower portion of the side wall of the Glen tank is inclined downward (for example, FIG. 1 of Japanese Utility Model Laid-Open No. 61-118221).

[Problems to be solved by the invention]

In this case, the storage amount of the tank was reduced by the amount of the lower part of the lower part of the side wall, and the part became a dead space. Therefore, it is conceivable to extend the side wall vertically and extend the narrowed part of the side wall by making the side wall and the bottom wall orthogonal to each other, but in this case, a bridging phenomenon of the grain or the like is likely to occur,
There is a drawback that causes discharge trouble.

Therefore, as a configuration that can expand the capacity according to the storage amount of the tank and reduce the storage amount to reduce the storage amount while suppressing the cross-linking phenomenon, there are the following proposals. It was As one of those things,
There is a device disclosed in Japanese Utility Model Laid-Open No. 61-69946, and the gist of the invention is that the left and right bottom wall parts are pivotally supported up and down with respect to the central bottom part of the lower part of the transverse feed screw, and the left and right bottom parts are pivotally supported. It is configured to be switchable between a contracted state in which the wall portion is inclined and an expanded state in which the left and right bottom wall portions are aligned with the central portion of the bottom surface.

With the above configuration, the bridging phenomenon is unlikely to occur, and the tank capacity can be changed, but since the tension spring as the urging means is inside the tank, each time the tension spring repeatedly expands and contracts. , There was a risk of biting the grain, and there was a structural problem.

The purpose of the present invention is to make a simple modification to the corner of the tank and to rationalize the installation location of the cover to increase the storage amount without causing discharge trouble, and
The point is to provide the thing which can avoid the trouble by the biting of a grain, etc.

[Means for Solving the Problems]

The featured feature of the present invention is that it has a horizontal feed screw (2) at the bottom.
The bottom corner of the Glen tank (1) provided with a lower side wall (11) pivotally supported with respect to the tank bottom wall (14),
Upper side wall pivotally supported on the side wall (9) of the tank
(10), the upper side wall part (10) and the lower side wall part (11) are connected to each other so that the tip parts thereof can be bent and swung freely, and the upper side wall part (10) and the lower side wall part are formed. (11) and the inclined contraction state which is set in a straight line, the upper side wall portion (10) and the lower side wall portion
(11) is configured to be switchable to an expanded state in which it is at a right angle, and is provided with a biasing means (15) for biasing the contracted state, the tank bottom wall (14) and the lower side wall portion (11) Connection point (Y), a connection point (X) between the tank side wall (9) and the upper side wall portion (10), a connection point between the lower side wall portion (11) and the upper side wall portion (10), In each case, an elastic cover (16,
17,18) is provided, and the biasing means (15) is located outside the elastic cover (16,17,18).
The effect is as follows.

[Action]

In other words, when the grain storage amount increases, the upper wall portion and the lower wall portion, which are in a straight line, in a tilted and reduced posture, are oscillated and widened against the biasing force by the own weight of the grain, and are substantially right angled. It is bent and deformed into an expanded state. (The state shown by the phantom line in FIG. 1). Then, when the discharge progresses from this state and the remaining amount becomes small and the output of the grains becomes poor, the upper side wall portion and the lower side wall portion are returned to the inclination reducing posture by the urging force of the urging means. The grain of can also be discharged.

Then, as described above, even if the upper side wall portion and the lower side wall portion swing due to the residual amount of the grain, the connecting point is covered by the cover, and the biasing means located outside the cover is provided. Since the arrival of the grain is blocked, the biting of the grain as in the conventional case is small.

[Effect of device]

Therefore, it is possible to effectively prevent the biting of the grain,
It has become possible to more effectively utilize the structure for expanding and contracting the tank capacity by swinging the upper side wall and the lower side wall.

〔Example〕

As shown in FIG. 4, while the traveling machine body (6) having the pre-mowing treatment device (5) attached to the front is supported by the crawler type traveling device (7), the grain transferred from the pre-mowing treatment device (5) is conveyed. A threshing device (not shown) that applies a handling action to the culm and a Glen tank (1) that stores the first product from this threshing device
(6) installed in parallel, with respect to this Glen tank (1), a horizontal feed screw (2) at the bottom, and a vertical screw that discharges the most grain from this horizontal feed screw (2) out of the machine Transport tube
(3) and the horizontal screw transport cylinder (4) are provided to configure the grain collection device (A) to configure a combine.

The shape of the crawler belt (8) of the crawler traveling device (7) will be described. As shown in FIGS. 2 and 3, two ribs (8A), (8B) of short length are equally spaced in the longitudinal direction of the crawler belt (8).
The crawler belt surrounded by the longitudinal ends (8C) of the short ribs (8A) protruding outward and the front and rear long ribs (8B) and (8B) sandwiching the short ribs (8A). 8) The bottom surface portion (8a) is formed so as to hold the mud on the farm surface. Therefore, it is possible to suppress the slip of the traveling device (7) at the time of turning due to the hugging force of the mud, and to prevent the soil from being pushed out to push down the planted seedlings by hugging the mud. Also, since the inner surfaces (8b) at both widthwise ends of the crawler belt (8) corresponding to the bottom surface portion (8a) are formed in a plane parallel to the ground contact bottom surface, even if a clod is laid on this inner surface. The crawler traveling device
