Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an opening/closing portion of the handling chamber forming wall that corresponds to the upper part of the alligator and the suction port, and is located on the opposite side of the alligator from the handling port. The present invention relates to a threshing device which is attached to a vertically swinging machine with a shaft circumferentially extending in the longitudinal direction, and a handling barrel is attached to an opening/closing part indicated by a TIFL, so that cleaning and inspection of the inside of the handling chamber can be easily carried out.

Conventionally, in the above-mentioned threshing device Hiiragi, as shown in FIG.
The boundary line (1) between the opening/closing part (3a) and the other part (3b) of the handling chamber (3) forming wall is the opposite handling opening 0 of the waniro (19).
■The opening/closing part (3a) was formed in sections so as to intersect with the side edges, but the opening/closing part (3a) had a large contact during the closing operation at the intersection where strength was a problem because it was originally a corner corner of two plates. Because the force acts, separate reinforcing members must be provided at the intersections, or the wall members must be made stronger, resulting in disadvantages in terms of manufacturing and manufacturing costs.<+', a!
There was 1 B.

In view of the above-mentioned circumstances, an object of the present invention is to provide a rational and partial improvement to the divided shape of the handling chamber forming wall, and to reduce the required strength at the intersection of the dividing boundary line and the wall.

A characteristic configuration of the present invention is that, in the above-mentioned threshing device, the handling chamber forming wall is divided into sections such that a boundary line between the opening/closing portion and other portions thereof intersects with the middle portion of the upper edge of the alligator. Its functions and effects are as follows.

In other words, this is an extremely simple improvement in which the division boundary line is simply rearranged so that it intersects with the middle gate part of the upper edge of the wanilo, compared to the conventional configuration in which it intersects with the edge of the ash outlet side of the waniiro. As a result, it is possible to provide a sufficiently large distance between the swing axis of the opening/closing part located on the opposite side of the handling opening and the crossing part, so that the opening/closing part does not act on the crossing part when closing the opening/closing part. It is possible to significantly reduce the contact force due to the moment around the swing axis, and as a result, the required strength at intersections, where strength is originally an issue, can be greatly reduced, making it possible to significantly reduce the strength required for wall members and The reinforcing member can be made lighter and smaller, which makes it extremely advantageous in terms of manufacturing and manufacturing costs.

Next, embodiments of the present invention will be described in detail based on illustrative drawings.

The processing cylinder drive pulley is linked via the processing cylinder drive pulley, and the processing cylinder drive pulley is directly connected to the processing cylinder rotation shaft (2a). The winding path of the power transmission belt i wound around the three pulleys of J-1241 is arranged concentrically with the opening/closing swing axis (■), and the relay pulley (26a) and the relay pulley (26a) placed close to it are connected. !J-
(26b), the handling cylinder driving pulley (2) is arranged so that the path length of the winding portion for the second rotation is maintained at a substantially constant length regardless of the vertical swinging of the opening/closing portion (3a). Inspection and cleaning inside the chamber (3) can be easily carried out with the opening/closing part (3a) open and held in a large space, and the opening operation can be easily performed without removing the transmission belt. It is configured as follows.

In addition, the recess in the figure is the opening/closing handle attached to the opening/closing part (3a), and the (support) is for resisting the heavy sea of the opening/closing part (3a) when the opening/closing part (3a) is open. The front wall has an opening/closing part (3a) and other fixed parts (
3b) is a pneumatic cylinder type buffer holder installed over the 3b). Furthermore, (29) is a fixture for fixing the opening/closing part (3a) to the closed part against the expansion biasing force of the buffer holder (28).

To configure the split structure of the front wall, the lower half of the boundary line (1) between the opening/closing part (3a) and the other fixed side part (3b) is located near the pivot support of the handling barrel rotation shaft (2a). The upper half of the boundary line to be read quickly is placed in the vertical direction so as to intersect with the middle part of the upper edge of Wanilo Uω, and the upper half of the boundary line to be read quickly is moved upward as it approaches the opening/closing swing axis (Q). The opening/closing part (3a) is arranged in an inclined manner so that the overall boundary line (1) is formed in a bent shape, and the opening/closing part (3a) is arranged in a state where the boundary line (1) as a whole extends almost the entire length of the boundary line (1). Flange-shaped receiving member sides are attached to the boundary line edge and the boundary line edge of the fixed side part (3b), respectively, so that the opening/closing part (3a) abuts against each other in the closed state.

By providing the slanted portion on the tab and the dividing boundary line (1), the opening/closing portion (3a
) has been improved in the vertical direction, and the intersection of the division boundary line (I) and the upper edge of the alligator (I9) has been placed as far as possible toward the axis of the handling barrel rotation axis (2a). 1. The distance between the closing swing axis (Q) and the intersection is sufficiently large, so that the contact force that acts on the intersection when the opening/closing part (3a) is closed is The aim is to reduce the moment of contact between the two parts as much as possible, and to reduce the required strength of the intersection part, where strength is a particular problem since it is originally a corner corner of the plate, thereby making the intersection part lighter and smaller.

Note that the division boundary line <1> that intersects the middle part of the upper edge can be modified in various ways, such as forming it in a straight line or a bent shape, instead of forming it in a bent shape. The specific bias ratio of the intersection part to the handling opening t20) side with respect to the entire center of Waniro 09) can also be changed as appropriate.

In addition, the specific swinging opening/closing form of the opening/closing portion (3a) is based on the axis (
Instead of the rotation around 01, it may be constructed in a swinging opening/closing mode that includes a parallel movement component with substantially the axis (Ql as the swinging fulcrum).
