Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a traverse screw conveyor for traversing a processed product after threshing and sorting to the outside of a sorting chamber at the bottom of the sorting chamber. The present invention relates to a threshing device provided with a lid that can swing and open and close with respect to a cleaning port formed in a gutter of a conveyor.

[0002]

2. Description of the Related Art Conventionally, in this type of threshing apparatus, an operation lever for opening and closing a cleaning port formed in a gutter of a screw conveyor is provided at a laterally outer portion of the machine body, and a lid linked to the operation lever is provided. To open and close the body,
When the lid is closed, the operation lever can be fixed and held in the closed state. When the lid is opened, the fixed state of the operating lever when the operating lever is closed is released, and the operating lever is swung along a plane along the longitudinal direction of the machine.

[0003]

However, in the above-described conventional threshing apparatus, when the cover is opened, the operating lever is moved from the fixed position in the closed state to a position where the swinging motion is made along the front-rear direction. Just because there was no clear indication to the operator whether the lid is closed or open, there is a risk that the operation of closing the lid may be forgotten and reaping work may be performed, so the sorting process was performed. There is a possibility that the processed material may leak below the cleaning port.

[0004] The present invention has been made in view of the above-mentioned circumstances, and even if the operator forgets to close the lid for performing cleaning or the like on the transverse screw conveyor, the operator is notified of this. To provide a threshing device that can be recognized with high certainty.

[0005]

(Structure) A threshing apparatus according to claim 1 of the present invention comprises a horizontal feed screw conveyor for horizontally feeding a threshed and sorted processed product to a lateral outside of a sorting chamber. A threshing device arranged at the bottom of the sorting chamber and provided with a lid that can swing and open and close with respect to a cleaning port formed in a gutter of the lateral feed screw conveyor, for opening and closing operation linked to the lid. The operation lever is arranged on the lateral outside of the sorting chamber, and a locking tool for locking and holding the operation lever in the closed position is provided, and the operation lever is released by releasing the locked state with the locking tool. When the swinging operation is performed to the side where the lid is opened, a regulating means for regulating the operation lever so as to protrude laterally outward from the locked state is provided.

(Operation) According to the configuration of the first aspect of the present invention, the operation lever for closing the cleaning opening lid is regulated so as to project laterally outward beyond the locked state at the time of closing. Even if you forget to close the cleaning port after cleaning the horizontal feed screw conveyor through the cleaning port of the gutter, if you attach a cover that covers the operation lever so that it will not be exposed to the outside of the fuselage. When the operation lever hits the cover, the cover cannot be mounted. Therefore, the operator notices that the cleaning port is not closed because the cover cannot be attached, and operates the operation lever to close the cleaning port with the lid. Further, when the lid is closed, the operation lever does not protrude laterally outward of the body, so that the cover can be attached to the body.

(Effect) Therefore, according to the configuration of the first aspect of the present invention, the fact that the operation lever is not in the closing operation state is simply determined by the posture in which the operation lever projects laterally outward of the body by the restricting member. By simply remodeling it, it is possible to eliminate forgetting to close the operation with the operation lever, so that it is possible to simplify the structure and to avoid forgetting to close the cleaning port with high certainty. Was.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an example of a combine. In this combine, a cutting pretreatment device 3 is attached to a front end portion of a body frame 2 supported by a pair of right and left crawler traveling devices 1 and 1 so as to swing up and down around a horizontal axis and a threshing device 4 and a boarding device. An operation unit 5, a Glen tank 6, and the like are mounted and mounted on the body frame 2.

As shown in FIG. 1 and FIG. 2, the culm which has been cut by the pre-cutting device 3 is supplied with a tip portion into a handling room 8 of the threshing device 4 while the stock is held and transported by a feed chain 7. It is threshed. That is, the threshing device 4
A processing cylinder 9 that is rotatably driven around a front-rear axis in a handling chamber 8, and a treated product that leaks a receiving net 10 disposed along a lower peripheral surface of the handling cylinder 9, An oscillating sorting device 11 for sorting and processing the processed material discharged from the rear end of the receiving net 10 is provided, and a Karamin 12 for supplying a sifting wind toward the oscillating sorting device 11 is provided at a lower front side. A horizontal feed screw conveyor 13 for collecting the most selected grains from the sorting apparatus 11 and transferring the grains to the right and outside from the sorting chamber S, and a second article from the swinging sorting apparatus 11. A horizontal feed screw conveyor 14 for collecting the second product, which is transported to the right and outside of the sorting chamber S, is disposed at the bottom of the sorting chamber S. A lifting screw conveyor 15 for lifting grains into the Glen tank 6 is interlocked to a transport end of the horizontal screw conveyor 13. On the other hand, a reduction device 16 for returning the second product to the front side of the swinging sorting device 11 and reducing the second product is linked to the transport end portion of the horizontal screw conveyor 14.

As shown in FIG. 1, FIG. 3 and FIG. 5, below the feed chain 7 and on the left lateral side of the sorting chamber S, a belt-type belt disposed on the lateral outer side of the left vertical wall of the sorting chamber S. Side covers 18 and 19 are detachably attached to close the transmission mechanism 17.

As shown in FIGS. 2 to 5, each of the horizontal feed screw conveyors 13 and 14 is provided with conveying screws 13 and 22 on troughs 21 and 22 formed on the bottom plate 20 of the sorting chamber S, respectively.
a, 14a, and each gutter 21,
22 has cleaning ports 23 and 24 formed therein. The cleaning ports 23 and 24 are arranged side by side along the width direction of the sorting chamber S. Then, for each of the gutters 21 and 22, the cleaning port 2 is provided.
Long sheet metal lids 25, 26 that can open and close 3, 24
Each is provided so as to be swingable around the horizontal axis cores P1 and P2. Each of the lids 25 and 26 is interlocked with a horizontal shaft 29 which is rotatably supported by a sorting chamber S between the two lids 25 and 26 via a link mechanism 27 and 28 around a horizontal axis P3. An operation lever 30 is attached to the left end of the horizontal shaft 29 so as to be swingable around the front and rear axis X.
The operation lever 30 is elastically biased toward the inside of the machine by a spring 34. As shown in FIGS. 3, 4 (a) and 5 (a), the position of the operation lever 30 is restricted by swinging in the left-right direction while the operation lever 30 is in the posture along the vertical direction in side and front views.
