Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a grain bag packing / collecting device installed in, for example, a harvester, and more specifically, from the end of a grain conveying device extending from the lower part of the threshing device. A pair of discharge cylinders that guide the grains downward toward a pair of collection bags are branched and connected, and a switching plate for selectively switching and guiding the grains to either one of the discharge cylinders is provided at the left and right branch portions. The present invention relates to a grain bag stuffing and collecting device which is swingably provided around a fulcrum at its lower end.

[Conventional technology]

In the conventional recovery device, as shown in FIG.
Between the end surface of the switching plate (9) and the inner side surfaces of the left and right branch portions (8), the passage of grain is restricted to obtain a smooth swinging motion of the switching plate (9). A gap (S ₁ ) was formed.

[Problems to be solved by the invention]

However, in the above-mentioned conventional structure, there may be a case where a fine branch of a paddy with a branch is caught in the gap, and if the switching swing of the switching plate is performed in a state where such a paddy is caught, the caught paddy is branched to the left and right. Due to the sliding contact resistance with the inner wall of the section, a force that makes it difficult for the gap to act acts, and as the switching plate swings, the bite amount increases and eventually the operation of the switching plate may be stopped.

As a method for solving the above-mentioned problem, for example, as shown in FIG. 6, when the switching plate (9) is in the left / right switching guiding action posture, the inner surface of the branch portion (8) is contacted with the switching plate (9) in a state of being wrapped. Plates (22) and (22) are provided to control the leakage of grain, and while the switching plate (9) is swinging, a paddy with a branch or the like is formed between the end face and the inner surface of the branch portion (8). A structure with a large gap (S ₂ ) passing freely was considered. However, in the above-mentioned improved structure, there is no harmful effect that the grain is clogged between the switching plate (9) and the inner surface of the branch portion (8), but especially between the switching plate (9) and the contact plate (22) When grains or the like are sandwiched near the fulcrum (X), a large gap is opened between them on the free end side, which causes a new adverse effect that the grains leak.

The present invention provides a grain bag stuffing and collecting device capable of smoothly performing switching swing of a switching plate, eliminating clogging of grains, and performing a reliable grain branch guide action. It is an object.

[Means for solving problems]

A characteristic configuration of the present invention is that in the grain bag packing recovery device having the above-described configuration, the switching plate has a side edge portion and an inner side wall of the left and right branch portions within a switching swing range of the switching plate. At the point where the grains are arranged so as to have an interval through which the grains can easily pass, and at the grain guide positions set at the left and right ends of the switching swing range of the switching plate, the switching plate The position of the regulating member with respect to the switching plate is determined so that a space that regulates the passage of the grain is formed between the portion of the side edge that extends over substantially the entire length and the regulating member that extends from the inner side wall. The following are the functions and effects.

[Action]

(A) With the above characteristic configuration, during the switching swing of the switching plate, the grains are not caught between the switching plate and the inner side wall, and the switching plate can swing smoothly. B) According to the above characteristic structure, when the switching plate is in the switching guide working position, the switching plate and the regulating member are located on the same plane facing each other, and the distance between them regulates passage of the grain. Since the grain is not caught, even if the paddy with a branch is caught in the gap between the edges, if the switching plate starts to swing, the above action ( As described in (a), since there is a sufficiently wide gap between the side edge portion and the inner side wall of the switching plate within the switching swing range of the switching plate, the trapped paddy drops downward.

[Effect of device]

As described above, according to the present invention, even if a paddy-shaped paddy or the like is caught in the gap on both sides of the switching plate, smooth switching operation can be performed without hindering the switching swing motion of the switching plate.
Moreover, it does not leak into the collecting bag on the opposite side while the grain is being guided down.

〔Example〕

As shown in FIG. 8, the thresher (3) is mounted on the carrier (2) of the traveling vehicle (1), and the grain bag packing recovery device (A) according to the present invention is provided to form a harvester. There is.

As shown in FIG. 1, the bag claw collecting device (A) is provided from the end of a screw conveyor type grain conveying device (4) extending from the lower part of the threshing device (3) toward the upper rear side of the machine body. , A pair of discharge cylinders (7a), (7b) for guiding the grain downward toward a pair of collection bags (6), (6) supported in an upright position on the deck (5) at the rear of the fuselage. Set up and configured,

It is swingable around.

As shown in FIGS. 1 and 2, both ends of the swing support shaft (10) of the switching plate (9) extend to the outside of both sides of the branching portion (8), and the outside of the machine is manually operated. The lever (11) is fixed, and the automatic switching mechanism (12) is connected to the inner side. As shown in FIG. 3, the automatic switching mechanism (12) detects the grain of the grain full sensors (13a), (13b) provided on the inner surfaces of the middle portions of the left and right discharge cylinders (7a), (7b). The operation piece (15) of the solenoid (14) driven in response to the solenoid (14) is linked to the arm (16) extending from the support shaft (10), and the support portion (17) of the solenoid (14) and the arm (16) are connected. (2) is provided with a toggle spring (18) stretched between the support shaft (10) and the opposite end.
