Description

[Detailed description of the invention] [Industrial field of application] The invention is based on a method in which an arc-shaped catch net placed under the handling barrel is moved along the circumferential direction of the arc through a guide section provided inside the handling chamber. , relates to a receiving net attachment/detachment structure for a thresher that is configured to be inserted and removed from the upper part of a handling chamber.

[Conventional technology]

As for the attachment structure of the receiving net in the threshing equipment,
For example, as disclosed in Japanese Utility Model Application Publication No. 55-170942, a structure is used in which a crimp net is stretched over a semi-cylindrical receiving net support frame, and this receiving net support frame is bolted and fixed to the wall of the handling room. However, in recent years, research has begun on a threshing device in which the receiving net can be inserted and removed in a sliding manner from the upper part of the handling chamber of the threshing device in order to facilitate the attachment and detachment of the receiving net.

[Problem that the invention attempts to solve]

In the above-mentioned threshing device in which the receiving net is inserted and removed in a sliding manner, a structure that allows the entire receiving net to be easily inserted, fixed, and removed has not yet been established.

An object of the present invention is to obtain a structure that makes it possible to easily fix and take out the above-mentioned slide-insertion type receiving net while using an existing structure and reducing costs.

[Means for solving problems]

The feature of the present invention is that the structure for attaching and detaching the receiving net of the threshing device is configured as follows. In other words, an engaging part is provided at the leading end and a rear end of the receiving net in the insertion direction to engage and disengage from the receiving net in the inserting/extracting direction to a locking part fixed in the handling chamber, and a cutter is installed with a cutter for cutting straw. The member is swingable and fixed between a fixed position where the rear end of the receiving net loaded into the handling chamber is pressed and clamped to the frame in the handling chamber, and a fixing release position where the receiving net can be pulled out. The cutter mounting member is configured to fit into the fixed frame of the handling chamber in the released position.

[Effect]

When configured as described above, when inserting the receiving net into the handling chamber, the cutter attachment member is swung to the fixing release position, and the receiving net is inserted along the guide within the handling chamber. Thereby, the engaging portion of the receiving net engages with the locking portion in the handling chamber, and the receiving net is positioned. .

Next, to fix the catch net, as shown in FIGS. 5 and 3, for example, the cutter attachment member 27 is swung to the fixed position and the rear end of the catch net is pressed against the frame 26 in the handling room. By fixing, the entire receiving net is fixed.

For example, as shown in FIG. 5, when the cutter mounting member 27 is swung to the fixed release position when inserting and removing the receiving net, the cutter mounting member 27 is moved to the fixed frame 30.
Since the cutter 27b fits inside the cutter 27b, the operator can safely insert and remove the receiving net without touching the cutter 27b.

[Effect of idea]

As described above, when configuring the receiving net in a sliding type that can be inserted and removed, positioning can be easily performed using the engaging part provided on the receiving net and the fixed part at the rear end, and the existing structure can be easily positioned. It became possible to fix the net with a cutter attachment member, which made it possible to insert and remove the receiving net and fix it while suppressing the complexity of the structure, improving maintainability.

Furthermore, since the operator is prevented from touching the cutter when inserting and removing the receiving net, safety when inserting and removing the receiving net is also improved.

〔Example〕

Hereinafter, a threshing device which is an embodiment of the present invention will be described based on the drawings.

The entire threshing device is constructed as follows.
In other words, as shown in Figure 7, feed chain 1
The harvested grain culm, which has been held and conveyed in a sideways position by the threshing machine, is threshed by a handling cylinder 3 which is drivably suspended horizontally in a handling chamber 15 within the threshing device. Threshed paddy and relatively small straw waste leak through the receiving net 16 placed below the handling barrel 3, fall onto the grain pan 21 installed on the lower swinging sorting frame 17, and are shaken by the grain pan 21. The paddy is sent to the grain sieve 22 on the lower side while being sorted by specific gravity by the operation, and on the grain sieve 22, by the shaking operation and the air blowing action from the winnower 20, the paddy leaks and is collected in the first grain collection section 18. and,
The paddy with branches, etc. collected in the second material collection section 19 is sent to the processing chamber 11 parallel to the handling chamber 15 shown in FIG. It is threshed.

Next, the structure of the receiving net 16 will be described in detail.
As shown in the figure, a pair of arcuate front mesh frames 2a,
The crimp nets 4, 4 are stretched over the rear net frame 2b, and the locking holes 5 provided at the rear end of the front net frame 2a are inserted as shown in the figure.
A locking pin 6 provided at the front end of the rear catch net frame 2b is inserted into the catch net frame 2b, and the net is used as a set of arcuate catch nets 16.

Next, the support structure for the receiving net 16 on the side of the handling chamber 15 will be described in detail. As shown in FIGS. Guide portions 9a and 9b formed by bending wire rods are provided on the inner side surface of the outlet steel plate portion 8. The receiving net 16 is first assembled by attaching the front receiving net frame 2a.
As shown in FIGS. 3 and 4, the guide portions 9a,
9b and insert the guide parts 9a, 9b.
The front pin, which is the locking part 12 provided near the front end,
The front mesh frame 2a is positioned by engaging the engagement hole, which is the engaging portion 13 provided at the front end of the front mesh frame 2a. Then, the above-mentioned post-receiving net frame 2a is moved to the guide portion 9.
a, 9b and insert it, and engage the locking pin 6 provided at the front end of the rear net frame 2b into the locking hole 5 at the rear end of the front net frame 2a that has already been inserted. , an engaging portion 2 provided on the rear end frame of the rear receiving net frame 2b
The rear pin, which is the locking part 25 provided on the frame 26 installed on the back side of the handling chamber 15, is inserted into the engagement hole 4, and the positioning of both the rear receiving screen frame 2b and the front receiving screen frame 2a is performed. Do it.

Next, to explain in detail the fixing structure of the receiving net 16, as shown in _FIG . Rear receiving net frame 2 which is freely pivoted and inserted and loaded as described above.
b The rear end portion is pressed and clamped to the frame 26 by the cutter mounting member 27, and at this time, as shown in FIG. The cutter mounting member 27 is fixed by engaging the lock pin 29 which has been cut into a fixing hole 26a provided on the side surface of the frame 26.

To remove the receiving net 16, the aforementioned lock pin 29 is removed from the fixing hole 26a, and the tool rest 27 is swung around the horizontal axis _p1 as shown in FIG. Once inserted, the operator can safely pull out the rear net frame 2b and the front net frame 2a without touching the cutter 27b.
