Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a reinforcing structure for front and rear side plates of a handling chamber in a threshing machine for threshing stems and culms.

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

Generally, in the handling room of this type of threshing machine, the handling barrel is mounted on a shaft between the front and rear side plates of the handling room, but the front and rear side plates of the handling room are used for threshing because the stem culm entrance to the handling room must be opened. The feed chain side will be formed in a so-called cantilevered shape. However, the front and rear side plates of the handling chamber must support the handling cylinder that rotates at high speed, and the material to be handled that accumulates in the handling chamber will cause the front and rear side plates to move forward and backward. It is necessary to have excellent strength as it may be subject to large amounts of force.

Therefore, conventionally, as shown in Japanese Utility Model Application Publication No. 62-77534, a connecting rod was supported between the cantilevered front and rear side plates of the threshing feed chain to provide reinforcement. However, since this connecting rod remains as it is even when the handling cylinder cover is opened upward, it becomes a nuisance when carrying out inspection and maintenance in the handling room, and is one of the factors that causes a decrease in work efficiency.

[Means to solve the problem]

In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a reinforcing structure for the front and rear side plates of the handling chamber in a thresher that can eliminate these drawbacks. The base on the opposite side of the threshing feed chain 13 is rotatably supported at the front and rear edges of the handling barrel cover 4, which opposes the front and rear side plates 2 of the handling chamber in the closed position. Front and rear cover side plates 4d are provided integrally, and a support shaft 6 is rotatably supported between the sides of the threshing feed chain 13 of both cover side plates 4d, and front and rear hooks 7 are provided at both front and rear ends of the support shaft 6. While each is firmly fixed, the tip portion on the side of the threshing feed chain 13, which is cantilevered on the front and rear side plates 2 of the handling room, is
Each bracket 9a from which a pin 9 for engaging and disengaging each hook 7 is protruded is fixed, and the outer surface 9b of the bracket 9a and the opposing side surface 7a of the handling chamber of the hook 7 are connected to the support shaft 6. The bracket 9 is placed in a position in substantially the same orthogonal plane or in a lap position where the side surface 7a of the handling chamber of the hook 7 is slightly closer to the handling chamber 1 than the outer surface 9b of the bracket 9a.
a and the hook 7, and each of the hooks 7
The outer surface 9a of the bracket 9a is in contact with the side surface 7a of the handling chamber of the hook 7 when the handling barrel cover 4 is locked to the pin 9 in the closed position. The cantilevered threshing feed chain 13 side of the front and rear side plates 2 is supported in a pinched manner from the front and rear outside of the handling chamber 1 by a support shaft 6 and a hook 7 passing through between both cover side plates 4d when the handling trunk cover 4 is in the closed position. It is characterized by the fact that

With this configuration, the present invention utilizes a locking device that locks and fixes the handling barrel cover in the closed position, and interposes a connecting rod between the threshing feed chain side, which is cantilevered on the front and rear side plates of the handling room. It was designed so that it could be strongly reinforced.

〔Example〕

Next, one embodiment of the present invention will be described based on the drawings. In the drawing, reference numeral 1 denotes a handling chamber of the threshing machine, and a handling barrel 3 is rotatably mounted on a shaft between the front and rear side plates 2 of the handling chamber 1. A threshing feed chain 13 is also provided. On the other hand, reference numeral 4 denotes a handling barrel cover whose base opposite to the threshing feed chain 13 is pivotally supported by a pivot 4a in the upper part of the handling chamber 1 so as to be freely openable and closable. By inserting the stay 4b with a stopper pin attached to the bracket into the elongated locking hole 2a formed on the upper surface of the front and rear side plates 2 of the handling chamber, and locking the stopper pin on the upper surface of the front and rear side plates 2 of the handling chamber. It opens in a half-open shape, and then it can be opened in a fully open shape by going beyond the vertical line and leaning against the hopper 5. Incidentally, 2c is a stem culm entrance/exit opened in the front and rear side plates 2 of the handling room so that the side of the threshing feed chain 13 is cantilevered.

The handling trunk cover 4 includes front and rear first cover side plates 4d hanging down from both front and rear edges of the top plate 4c.
Furthermore, the front and rear second cover side plates 4e are arranged so as to be located on the inside of the handling chamber by a thickness l of the side plates 4d.
A support shaft 6 is rotatably supported through the threshing feed chain 13 side plate of the first cover side plate (corresponding to the cover side plate of the present invention) 4d, and the first cover side plate Engagement hooks 7 are integrally provided at both ends protruding outward from the first cover side plate 4d with a gap from the first cover side plate 4d, and an operating lever is protruded from the hook 7. There is.

On the other hand, the threshing feed chain 1 on the front and rear side panels 2 of the handling room
A bracket 9a having a hat-shaped cross section is fixed to the outer surface of the handling chamber at the tip of the third side, and a pin 9 is integrally protruded from this bracket 9a. When the handling barrel cover 4 is closed, the operating lever 8
By locking the hook 7 to the pin 9, the handling barrel cover 4 is locked in the closed position. The bracket 9a slides into the handling chamber so as to be opposed to the side surface, and the outer chamber surface 9b of the bracket 9a and the handling chamber side surface 7a of the hook 7 opposing this are located in substantially the same plane orthogonal to the support 6. By arranging the bracket 9a and the hook 7 in this manner, the side surface 7a of the handling chamber of the hook 7 comes into sliding contact with the outer surface 9b of the bracket 9a, thereby allowing the front and rear side plates 2 of the handling chamber to When the handling trunk cover 4 is in the closed position, a hook 7 is attached to the support shaft 6 which is supported through the two first cover side plates 4d that are in contact with each other.
The structure is such that it is supported in a pinched manner from both sides via the . On the other hand, the second cover side plate 4e is arranged inward by the plate thickness 1 as described above in order to reduce the sliding resistance when the handling barrel cover 4 is opened and closed. The front and rear edges of the outer surface plate 4f fixedly stretched between the outer edges of the cover side plate 4e project forward and backward from the second cover side plate 4e, and the projecting ends are bent inward to form a bent portion 4g. There is. When the handling barrel cover 4 is closed, the rib portions 2b formed at the tips of the front and rear side plates 2 of the handling chamber fit into the bent portions 4f, and here too, the front and rear side plates 2 of the handling chamber Support is now available.

Further, the handling cylinder cover 4 is provided with an inner wall 4h so as to substantially follow the rotation locus of the handling cylinder 3, and a brush 10 is provided at the tip of this inner wall 4h.
When the handling cylinder cover 4 is closed, this brush 1
0 comes into contact with the base end frame 11a of the receiving net 11 from the inside to prevent grains from scattering. However, when the handling barrel cover 4 is in the half-open state as described above, the receiving net 11 The net 11 is located at the removal locus position so that the receiving net 11 can be cleaned. In addition, 12
is a connecting member supported between the bases of the left and right handling chamber front and rear side plates 2 to support and fix the base end frame 11a of the receiving net 11.

In the embodiment of the present invention configured as described above, when closing the handling barrel cover 4, the operating lever 8
As a result, the hook 7 engaged with the pin 9 is locked in the closed position, but at this time, the front and rear first cover side plates 4d are recessed into the handling chamber, and the front and rear side plates 2 of the handling chamber are pushed against the side surfaces of the handling chamber. The front and rear hooks 7 are provided on the front and rear side plates 2 of the handling chamber, respectively, and are fixed to a support shaft 6 which is supported between the front and rear first cover side plates 4d. It will come into contact with each outer surface 9b of the bracket 9a.
As a result, the cantilevered threshing feed chain 13 side of the front and rear side plates 2 of the handling chamber is supported by a penetrating support between both first cover side plates 4d via the front and rear hooks 7 that are in contact with each other when the handling trunk cover 4 is in the closed position. It has a reinforcing structure that is supported in a pinched manner from the front and rear sides of the handling chamber by the attached support shaft 6, and it is firmly supported on the handling trunk cover 4 side without wobbling, and the threshing of the front and rear side plates 2 of the handling chamber is possible as usual. There is no need to connect and reinforce the ends of the feed chain 13 by connecting each other with a connecting rod. Therefore, when the handling barrel cover 4 is opened, the threshing feed chain 13 side of the handling room 1 has a wide opening without any interfering connecting rods, which facilitates inspection and maintenance of the handling room 1. This will improve work efficiency.

Moreover, in the example, the front and rear side plates 2 of the handling chamber are
Since the tip rib 2b is further supported by the bent part 4g on the side of the handling cylinder cover 4, reinforcement of this part, which is particularly unstable due to the cantilevered shape, is performed at two places including the support mentioned above. This means that the strength of the front and rear side plates 2 of the handling chamber can be significantly increased. Moreover, in this case, although the tip rib portion 2b is supported, the second cover side plate 4e does not come into sliding contact with the front and rear side plates 2 of the handling chamber, so opening and closing the handling barrel cover 4 becomes difficult. can also be avoided. Incidentally, there is a gap l between the second cover side plate 4e and the front and rear side plates 2 of the handling chamber, and this gap l is created because the rib portion 2b is supported in contact with the outer surface plate 4f and the bent portion 4g. , and your belongings will not leak out.

In addition, a brush 10 is provided on the inner wall 4h of the handling cylinder cover 4 to prevent the material being handled from scattering, but this brush 10 is also used as a cleaning tool when attaching and detaching the receiving net 11. It is also convenient. Of course, in this case, in order to obtain the cleaning action of the brush 11,
It is necessary to fully open the handling cylinder cover 4 to release the catch net 11, and then to partially open the rear handling cylinder cover 4 before pulling out the catch net.

It should be noted that the present invention is not limited to the above-mentioned embodiment in its implementation, but can also be implemented as shown in FIG. 8. In other words, in this case, the tip side of the hook 7 is bent outward to serve as a guide, and the side surface 7a of the handling chamber of the hook 7 is used as a guide.
enters the handling chamber 1 side slightly from the outer surface 9b of the bracket 9a and connects the bracket 9a and the hook 7 to a width K.
When the handling barrel cover 4 is in the closed position, the front and rear side plates 2 of the handling chamber fit elastically between the cover side plate 4c and the hook. As a result, the handling barrel cover 4 can be opened and closed reliably by the guide action, and the elastic support further improves vibration isolation.

[Effect]

In summary, since the present invention is constructed as described above, the handling trunk cover 4 is in the closed position, and the front and rear hooks 7 are fixed to both the front and rear ends of the support shaft 6 which is supported through the front and rear cover side plates 4d. are provided on the front and rear side panels 2 of the handling chamber at the respective ends of the brackets 9.
When the hooks 7 are locked to the pins 9 protruding from the handle a, the handling chamber side surfaces 7a of both hooks 7 come into contact with the outer surfaces 9b of the bracket 9a, and the threshing feed chain 13 side becomes cantilevered on the front and rear side plates 2 of the handling chamber. is the support shaft 6 and the support shaft 6
The front and rear hooks 7 fixed to the front and rear hooks provide a structure in which the handling chamber 1 is supported in a pinched manner from the front and back outside. As a result, the support shaft 6 and the hook 7 have the function of reinforcing the front and rear side plates 2 of the handling chamber in addition to their original locking effect on the handling barrel cover 4, making the front and rear side plates 2 of the handling chamber superior in strength and durability. Even if the handling cylinder rotates at high pressure and is supported, or even if a large force is applied to the front and rear sides of the handling chamber 1 due to the objects to be handled accumulated in the handling chamber 1, the front and rear side plates 2 of the handling chamber
will not be deformed or damaged.

In addition, the cantilevered front and rear side plates 2 of the handling chamber are reinforced by the support shaft 6 that extends between the front and rear cover side plates 4d. When you open the
As a result, the connecting rod does not remain as it is, unlike in the conventional case where the front and rear side plate tips are reinforced with a connecting rod.
Inspection and maintenance of the rope handling room 1 can be easily carried out, and work efficiency can be improved.
