Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a receiving net fixing device in a threshing machine for fixing a receiving net for receiving and sorting material unloaded from a handling drum.

[Problems to be solved by the prior art and the invention]

Traditionally, this type of seed net was placed inside the threshing machine.
It is a fixed type that is fixed directly to the machine frame of the threshing machine using fixing members such as bolts, and the receiving net is used to handle unloaded material containing a large amount of foreign matter. As the wet material clumps bounce around inside the handling chamber with great force as the handling barrel rotates, it receives a large load in the direction of rotation, and as a result, the receiving net can easily come off or shift its position. It must be firmly fixed to prevent it from falling. As a result, when attempting to remove the receiving net for inspection, maintenance, etc.,
It is necessary to tighten and loosen the fixing members each time using regular tools, and this work must be done in a narrow space, which makes the work extremely troublesome and complicated, so it is necessary to thoroughly clean every corner. In fact, it is difficult to inspect and maintain, and in addition, it is difficult to easily replace the receiving net in order to quickly handle a variety of grains.

[Means to solve the problem]

In view of the above-mentioned circumstances, the present invention was devised to provide a receiving net fixing device for a threshing machine that can eliminate these drawbacks. In a threshing machine equipped with a handling chamber cover formed with an arc-shaped cover surface that covers the upper surface of the handling chamber, the handling chamber cover includes:
A tightening tool for tightening and fixing the handling chamber cover in the handling chamber closed position on the side where the stock end of the grain stems to be supplied to the handling room is held and conveyed, and a handling chamber cover on the opposite side. In addition, the handling chamber cover is installed on the grain culm entrance and exit sides of the handling chamber so as to follow the rotation locus of the handling teeth installed in the handling barrel. A guide body is provided to slidably guide both front and rear edges of the receiving net toward a mounting frame fixed at the lower part of the handling room from the hinge support side of the receiving net, and the front and rear both edges of the receiving net are supported by the guide body. , the mounting frame is formed with a locking portion that receives and locks the lower edge of the handling chamber of the receiving net that is slidably guided, and furthermore, the handling chamber cover is formed on the hinge support portion side of the handling chamber cover. When the receiving net is blocked, a supporting member is provided which presses against the upper edge of the handling chamber of the receiving net from above in a press-contact manner to push the receiving net toward the lower side of the handling chamber and supports and fixes the receiving net at the mounting position. In order to cover the part where the support member presses against the upper edge of the handling chamber of the receiving net, the edge on the side of the hinge support part of the surface extends beyond the contact area to the upper end of the receiving net below. It is characterized by being elongated.

With this configuration, the present invention allows the receiving net to be firmly fixed and supported using the handling chamber cover, and also allows it to be attached and detached extremely easily without the need for tightening or loosening the fixing members. It is something.

The edge portion on the side of the hinge support portion 2d is set to cover the portion where the flat plate 12c presses against the frame body 15d, and extends beyond the contact portion to the upper end of the receiving net below.

In the embodiment of the present invention constructed as described above, when cleaning the receiving nets 14, 15, the receiving nets 14, 15 can be taken out from the handling room 4. That is, the receiving nets 14 and 15 have frame bodies 14 on both the front and rear sides thereof.
a, 15a are guide bodies 16, 16a and 17, 17
a, and is fixedly supported by being held by the mounting frame 13a and the handling barrel cover 12 on both left and right sides. To remove the receiving nets 14 and 15 in this state, the clamping tool 12b provided on the side that clamps and conveys the grain culm stock base is released, and the handling barrel cover 12 is installed on the opposite side of the clamping tool 12b. The handling chamber 4 is opened upward using the hinge 12a as a fulcrum.
All you have to do is open the plate 1.
The frame 15d of the receiving net 15 that was pressed by the receiving net 2c is exposed. Therefore, if the frame body 15d is grasped and pulled out, the receiving nets 14 and 15 can be moved to the guide bodies 16, 16a,
It is taken out from the handling room 4 while being guided by 17, 17a.

After cleaning the receiving nets 14, 15 taken out in this way, in order to reinstall the receiving nets 14, 15 in the handling chamber 4, first place the receiving nets 14 between the guide bodies 16, 16a and 17, 17a. Fit it and insert it into the handling chamber 4,
Next, the receiving net 15 is passed through the guide bodies 16, 16a and 17,
17a. At this time, the locking pin 15c on the side of the receiving net 15 is fitted and locked into the locking hole 14e on the side of the receiving net 14, so that both receiving nets 14 and 15 are connected in series. Then, the receiving nets 14 and 15 are pushed into the handling chamber 4 one after another. After the receiving nets 14 and 15 have been substantially inserted, the handling chamber 4 is closed with the handling chamber cover 12, and the handling chamber cover 12 is fixed with the fastener 12b. As a result, the receiving net 15
In this case, the frame 15d is pressed into contact with the flat plate 12c of the handling chamber cover 12, and the locking pin 14c on the receiving screen 14 side is inserted into the engagement hole 13b of the mounting frame 13a.
The other end of the receiving net 15 is supported by the handling chamber cover 12 so that the receiving nets 14 and 15 are fitted into and supported by the handling chamber 4.
It will be installed on.

In this way, in the present invention, receiving nets 14, 15
The receiving nets 14 and 15 can be inspected very easily by just one-touch operation to open and close the handling chamber cover 12, which is absolutely necessary to inspect the receiving nets 14 and 15.
It is possible to fix and hold the receiving nets 14, 15 in the installation position and release them, and therefore there is no need for tightening and loosening work using a dedicated fixing member tool that is troublesome as in the past. This not only greatly improves the ease of inspection and maintenance of the receiving nets, but also makes it easy to replace the receiving nets 14 and 15. It is also easy to make changes to correspond to the types of grains such as barley and soybeans.

Moreover, the receiving nets 14 and 15 are fixed by pressure contact with the handling chamber cover 12, not on the side where the fastener 12b is provided which is far from the hinge 12a, but close to the hinge 12a that swings and supports the handling chamber cover 12 so as to be able to swing open and close. Since it is carried out on the side, the weight of the handling chamber cover 12 itself and the tightening force of the fastener 12b act strongly based on the principle of leverage, providing strong fixed support. Receiving net 1 in a condition that can sufficiently withstand the load caused by the vigorous rotation of unloaded material containing a large amount of material or material with wet material in the form of clumps.
4 and 15 can be fixedly supported without making the handling chamber cover 12 particularly heavy or using fasteners with a particularly large tightening force.

Moreover, in this case, the handling chamber cover side flat plate 12
Since the part that comes into pressure contact with the frame 15d by c is covered by the edge on the hinge side of the cover surface 12d of the handling chamber cover 12, the contact part is directly exposed to the handling chamber 4. There is nothing to do, so the handling room 4
It is advantageous that the rotational resistance can be reduced and problems such as damage to the grains can be effectively prevented by making them arcuate as closely as possible to the rotation locus of the handling teeth 11.

Furthermore, in this case, since the receiving nets 14 and 15 are supported by the guide bodies 16, 16a and 17, 17a on both front and rear sides, the distance between the receiving nets 14 and 15 and the handling teeth 11 can be maintained accurately, resulting in good threshing work. can be done. Moreover, the receiving nets 14 and 15 are connected to the handling room cover 1.
2 and the mounting frame 13a, both sides of which are held in a pressed manner, can be firmly supported without any wobbling.

Incidentally, the present invention has a reception net 14, 1 as shown in FIG.
A rotating body 19 is provided on both the front and rear frames 14a, 15a of the receiving nets 14, 15, and guide bodies 16, 16a, 1
7, 17a may be made so as to allow smoother sliding on the receiving net.Furthermore, the receiving net does not necessarily have to be double-stranded and can be increased or decreased as appropriate, and the guide body can move the receiving net in a predetermined position. The mounting position is free as long as it is slidably guided to the desired position.

[Function and effect]

In summary, since the present invention is constructed as described above, by placing the handling chamber cover in the closed position, the receiving net is pressed into contact with the supporting member provided on the handling chamber cover, Both upper and lower ends are supported and fixed by the support member and the mounting frame. Therefore, it is not necessary to perform the troublesome and complicated tightening work using a special fixing member tool with the handling room cover open as in the past, and it is possible to attach and remove the catch net. By opening and closing the handling room cover, which is absolutely necessary, it is possible to fix the support in the mounting position and release it.As a result, the inspection and maintainability of the receiving net is significantly improved, and cleaning etc. can be performed easily. In addition, the receiving net installed in the handling chamber is supported by guide bodies on the front and back, making it easy to manage the spacing between the handling teeth. Since it is held in a pinched manner, it can be firmly supported without any wobbling.

In addition, the pressure welding and fixing of the receiving net using the handling chamber cover,
Not on the side where the fastener is located farthest from the hinge support,
Because this is done on the side close to the hinge that swings and supports the handling chamber cover so that it can swing open and close, the weight of the handling chamber cover itself and the tightening force of the fasteners act strongly based on the principle of leverage. As a result, it is possible to provide strong fixed support, and as a result, it is possible to avoid the load caused by unloaded material containing a large amount of foreign matter or material made of wet material that rotates vigorously following the rotation of the handling cylinder. It is now possible to securely support the receiving net in a state where it can withstand even heavy loads without making the handling room cover particularly heavy or using fasteners with a large tightening force, which also contributes to making the net lighter and more compact. .

Furthermore, the edge of the arcuate cover surface on the side of the hinge support portion is extended downward to cover the portion that presses against the edge of the upper side of the handling chamber of the receiving net, and as a result, as described above, Even if the support member presses and supports the receiving net from above, the contact support part is not directly exposed to the handling room and is covered by the cover surface. This has the advantage that it can be made into an arc shape that follows the rotation locus of the handling teeth as much as possible, reducing the rotational resistance of the handling barrel and effectively preventing problems such as damaging the grains. be.
