Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a threshing device in which an upper handling case having a handling barrel mounted thereon is supported so as to be openable and closable with respect to a lower handling case.

[Conventional technology]

As the above-mentioned threshing device in the past, for example, the actual Kaisho 63-1
As disclosed in Japanese Patent No. 51720, there has been a structure in which a receiving net is divided into two and each divided receiving net is detachably attached and fixed to the center side of the handling room.

[Problems to be solved by the device]

The above-mentioned conventional structure is configured so that the net can also be easily removed when the handling cylinder is rocked and opened upward, but as described above, the net is fixed in position during threshing work. Since the threshed products start to get entangled in the mesh, the processed products are deposited one after another and adhere to each other. Therefore, there is a drawback that maintenance work such as cleaning due to clogging in the handling room must be frequently performed.

And as a method of solving the above problems, it is possible to vibrate the receiving net during threshing work to reduce the adherence of the processed material, but to vibrate the receiving net, the arc-shaped both end portions of the receiving net, It is necessary to provide a U-shaped rail that is sandwiched in the thickness direction, but with this configuration, when removing the receiving net for cleaning etc., the upper parts of the rails at both ends must be removed, respectively. However, even when re-installing, it is difficult to perform the mounting position alignment work on the upper part of the rail, which causes new problems such as being troublesome.

The purpose of the present invention is to pay attention to this point, and to reduce the clogging of the processed material to the net as much as possible and to easily attach and detach the net. It is in.

[Means for Solving the Problems]

A feature of the present invention is that, in the threshing device, an upper guide member and a lower guide member that sandwich the front and rear edges of the net from the thickness direction are provided in the lower shell case, and the net is arranged in the circumferential direction of the shell. The upper guide member is supported so as to be reciprocally movable along the lower handle body side so as to be swingable around an axis of one end between an operating position for supporting the receiving net and a non-operating position for opening the upper guide member upward. And its action
The effects are as follows.

[Action]

That is, even if the threshing-treated product starts to get entangled in the mesh by vibrating by supporting the receiving net movably in the circumferential direction by the both guide members, shaking off the treated product by vibration. It is possible to prevent clogging in a short period of time. In addition, when the receiving net is removed, the upper guide member can be pivotally opened upward about the axial center so that the receiving net can be easily removed upward, and the upper guide member can be reattached. Need only be rocked downward and no complicated alignment is required.

[Effect of device]

Therefore, according to the present invention, it is possible to prevent clogging in the receiving net in a short period of time and reduce the frequency of maintenance work. Moreover, in the maintenance work, the receiving net is only moved by swinging the upper guide member. As I can put it on and take off,
Compared to the case where the guide members on both sides are attached and detached, it can be performed easily and without trouble.

(15), (15) and lower guide members (16), (16) are provided, and the receiving net (4) is supported between them so as to be reciprocally movable. Further, the receiving net (4) is configured to be forcedly vibrated by the forced vibrating mechanism (17) provided on the upper part on the inner back side.

The forced vibration mechanism (17) is configured as follows. Second
As shown in Fig. 5 and Fig. 5, a pair of eccentric shafts (21) are rotatably driven through the output pulley (18) attached to the handle shaft, the transmission belt (19) and the input pulley (20). Core member (22), (22)
Each eccentric member (22) is connected to the middle part of the swing arm (23) whose one end is pivotally supported by the side wall via the plate (24). At the swing end of the swing arm (23), the net
The roller (25) supported on the outer surface of the end of (4) is provided with an engaging portion (26) which is slidably engaged from both sides.

Next, the support structure of the receiving net (4) will be described. As shown in FIG. 1, a semi-circular receiving net support frame (27) is attached and fixed to the lower handling case (14), and the guide members (15) are attached to both ends of the receiving net support frame (27). ) And the lower guide member (1
