Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a horizontal screw conveyor that conveys No. 2 processed material from a sorting unit to the side of the machine body, and the processed product from this horizontal screw conveyor to the sorting unit or A vertical screw conveyor for hoisting and feeding to the reprocessing unit, and an intermediate transfer for feeding the processed product from the horizontal screw conveyor to the vertical screw conveyor by means of a rotary blade integrally rotatably attached to the screw shaft of the horizontal screw conveyor. The present invention relates to a processed product conveying member structure for a threshing device, which is provided with a device, the drive shaft of the vertical screw conveyor and the screw shaft are arranged in parallel, and a transmission mechanism for transmitting power from the screw shaft to the drive shaft is provided.

[Conventional technology]

In the above threshing device, conventionally, for example, JP-A 64-43135
As disclosed in Japanese Patent Laid-Open Publication No. 2003-242242, an opening that allows internal cleaning of the blade case in the intermediate transfer device is formed in the peripheral wall portion of the blade case.

[Problems to be solved by the device]

Conventionally, in order to enlarge the case opening, it is necessary to increase the length of the blade case in the blade rotation axis direction, and if this length is expanded, the length of the rotation blade in the rotation axis direction becomes meaningless. Since the length of the intermediate transfer device protruding from the side wall of the threshing device becomes large as the size increases, the case opening cannot be formed so large. Further, since the case opening is oriented in the radial direction of the rotary blade, cleaning and inspection of the rotary blade requires rotating operation of the rotary blade. Therefore, cleaning and inspection of the inside are relatively difficult.

An object of the present invention is to modify the case so that the inside of the case can be easily cleaned from the size of the opening of the blade case and the opening / closing operation surface.

[Means for solving the problem]

In order to achieve the object, the structure of the processed product transport section of the threshing device according to the present invention is the same as that described at the beginning, and the side wall of the blade case of the intermediate transport device is detachably attached in the axial direction of the screw shaft. The input member and the output member of the mechanism are supported by the transmission case of the transmission mechanism, and the input case is moved by operating the transmission case in the axial direction with respect to the screw shaft and the drive shaft. On the other hand, the input member and the output member are formed such that the output member is engaged with and disengaged from the drive shaft, respectively, and the side wall is provided with a connecting portion with the transmission case.
The action and effect are as follows.

[Action]

Even if the side wall of the blade case is configured to be connected to another case portion, the side wall and the transmission mechanism can be operated by moving the transmission case with respect to the screw shaft and the drive shaft in a state where the connection is released. The input member and the output member of are moved along with the transmission case, and these are disengaged from the blade case body or the screw shaft or the drive shaft to open the blade case, or the blade case body or the screw shaft or the drive shaft is attached to the blade case. When is closed, the transmission mechanism is put in the mounted state.

When the side wall of the blade case is removed, the blade case opens in the direction of the axis of rotation of the rotary blade, and the blade case has a large opening for the protrusion length from the wall of the threshing device. Faces the opening, so that a hand or a cleaning tool can easily reach the inside of the blade case and the entire rotary blade.

[Effect of device]

Large opening of the blade case of the intermediate transfer device, and
With the opening facing the axial center of the rotary blade, it can be opened for easier and more efficient cleaning and inspection.

In addition, by assembling and dismounting the transmission mechanism, the side walls can be assembled and disassembled all at once, and the efficiency of cleaning and inspection can be improved even from the opening / closing surface of the intermediate transfer device.
