Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to the structure of the sorting section of a threshing device.

[Conventional technology]

In the threshing device, for example, as shown in FIG. 3, there is an upper stroke rack that receives the material falling from the threshing room 2 and sorts the paddy while swinging it to the upper part of the second material collecting section 8. 11.Catch the material falling from the end of the upper stroke rack 11,
Some are equipped with a lower stroller rack 15 that sorts out the paddy while swinging it to near the discharge port.

The lower stroke rack 15 is installed between the left and right side plates of the swing sorting case, and connects the front ends of a plurality of rack plates 15b each having a serrated upper surface to the stay 15a, so that the rack plates 15b are aligned in the left-right direction. The rack plate 15b extends rearward. The paddy leaking from the upper and lower straw racks 11 and 15 is collected by the second product collection section 8.

In the serrated upper surface of the plurality of rack plates 15b of the lower stroke rack 15 in FIG. ) second
The sawtooth portion is formed into a gently sloped surface. In this case, in the first and second sawtooth sections, the first sawtooth section, which has a steep slope, has a weak backward feeding effect on the processed material;
In the second sawtooth section where the slope is gentle, the action of feeding the processed material backward is stronger.

This is to prevent the paddy contained in the processed material from the upper straw rack from being sent to the discharge port from the latter half of the lower straw rack before it has been sufficiently sorted and leaked in the first half of the lower straw rack. This is to weaken the feeding action of the first serrated portion on the front half of the lower stroke rack so that the paddy can be well sorted and leaked in the front half of the lower stroke rack.

[Problem that the invention attempts to solve]

In the conventional structure described above, for example, as shown in FIG.
In some cases, the vehicle may ride in a bridge-like manner over the distance a.

In such a state, no matter how much the swinging sorting case swings, the long straw A remains stuck between the first serrations in the front half of the lower stroke rack 15 and is not sent rearward. And finally, Nagawara A
However, it falls into the first object collection section 7 from the first distribution lower plate 7a.

The object of the present invention is to provide a structure in which even if the long straw is in the state shown in FIG. 3, it can be sent rearward by the lower stroke rack and discharged.

[Means for solving problems]

The feature of the present invention is that the structure of the sorting section of the threshing device as described above is configured as follows.
That is, on the serrated upper surfaces of the plurality of rack plates arranged in parallel in the lower stroke rack, the first serrations on the side of the first object collecting section are formed into inclined surfaces facing diagonally downward on the side of the first object collecting section, The second sawtooth section on the discharge port side is formed into a slope that is gentler than the first sawtooth section and faces diagonally downward on the first item collection section side, and is connected to the front ends of the plurality of rack plates to form a swing sorting case. Below the rear extension line of the imaginary line connecting the upper end of the stay installed between the left and right side plates and the rear end of the first distribution lower plate,
A first serration of the rack plate is located.

[Effect]

() For example, as shown in FIG. 1, the long straw is formed into a bridge shape between the No. 1 flow down plate 7a on the No. 1 material collection section 7 side and the stay 15a of the lower stroke rack 15 (the position of the imaginary line a). Suppose you ride it. In this case, if the configuration is as described above, the first sawtooth portion 15c of the rack plate 15b will be located below the long straw (see imaginary line a).
The long straw does not enter between the first sawtooth portions 15c, and the long straw can freely move in the left-right direction of the lower straw rack 15.

Therefore, in this state, the swinging sorting case 5
When the straw swings, this vibration causes the long straw to turn sideways, catch the first serrations 15c, and be pulled up onto the lower stroke rack 15. Thereafter, the long straw is fed over the lower stroke rack 15. It is sent to the discharge port 9.

() In the case of this FIG. 1, on the rack plate 15b of the lower stroke rack 15, the first sawtooth part 15c on the side of the first object collecting section 7 is formed into a steep slope, and the second sawtooth part on the side of the discharge port 9 is formed. 15b is formed into a gentle slope.

Therefore, in order to prevent the paddy contained in the processed material from the upper stroke rack from being immediately sent backwards, the feeding action of the first sawtooth section on the front half of the lower stroke rack is weakened, and the lower stroke is It still has the advantage of the conventional structure, which allows the paddy to be well sorted out in the first half of the rack.

[Effect of idea]

As mentioned above, even if long straw is placed on the No. 1 distribution lower plate and the lower stroke rack stay,
It is now possible to discharge long straw and prevent it from falling into the No. 1 material collection section, maintain the quality of paddy collected in the No. 1 material collection section, and improve the sorting performance of the threshing device. was completed.

Furthermore, the purpose can be achieved by a slight modification of lowering the first serrations of the lower stroke rack, which is advantageous in terms of manufacturing costs.

The conventional structure prevents the paddy contained in the processed material from the upper straw rack from being immediately sent to the rear, and allows the paddy to be well sorted and leaked in the first half of the lower straw rack. Since it still has the advantages, the present invention does not have any disadvantages that would detract from the advantages of the conventional structure.

[Example] A threshing device that is an example of the present invention will be described below with reference to the drawings.

As shown in FIG. 2, a clamp net 3 is stretched below a threshing chamber 2 in which a handling cylinder 1 is horizontally suspended in a freely drivable manner, and a discharge port 4 is provided on the lower side of this clamp net 3. The harvested paddy and straw waste are placed in a clamp net 3.
The liquid leaks or is discharged from the discharge port 4 and falls into the swinging sorting case 5 which has various sorting mechanisms located below.

Then, the paddy is sorted by the swinging action of the swinging sorting case 5 and the blowing action from the winnowing machine 6, and is collected in the first pick collection section 7 and the second pick pick up section 8.
The threshing device is configured such that the straw waste is discharged from the threshing device through the discharge port 9 by the swinging action of the swinging sorting case 5 and the absorption action of the dust exhaust fan 14.

Next, we will discuss the oscillating sorting case 5 to which the present invention is applied.
I will explain about it. As shown in FIG. 1, the paddy and relatively small straw waste that have leaked through the clamp net 3 fall onto the chaff sheave 10 located below the clamp net 3, and the paddy and small straw waste leak further downward. down. On the other hand, the paddy with branches is sent from above the chaff sheave 10 to the upper stroke rack 11 on the lower side by its swinging motion.

The paddy and small straw waste that have leaked through the chaff sieve 10 fall onto the grain pan 12 and are sent to the net-like grain sieve 13 while being sorted into layers. Ru. The straw waste is discharged out of the threshing device by the blowing action from the winnowing machine 6 (see FIG. 2) and the absorption action of the dust exhaust fan 14 (see FIG. 2).

The upper stroke rack 11 has a chaf sheave 1.
The paddy with branches that did not leak through the clamp net 3 and the long straw that was discharged from the discharge port 4 without leaking through the clamp net 3 are sent in. This upper stroke rack 1
1 has a structure in which serrated rack boards are arranged parallel to each other at regular intervals, and paddy with branches, which are relatively small compared to long straw, leak between the rack boards and reach the second rack. The long straws are collected by the collecting section 8 and fed onto the lower straw rack 15 located below the upper straw rack 11 on the downstream side.

The lower stroke rack 15, like the upper stroke rack 11, has a plurality of serrated rack plates 15b arranged in parallel at regular intervals on a stay 15a that is suspended horizontally between the left and right side plates of the swing sorting case 5. As shown, the front end of the rack plate 15b is fixed.

As shown in FIG.
On the sawtooth-like upper surface of the plurality of rack plates 15b, a first sawtooth portion 15c on the side of the first object collecting section 7 is formed.
is formed on an inclined surface facing diagonally downward on the side of the first item collection section 7, and the second sawtooth section 15d on the side of the discharge port 9 is formed on the first sawtooth section 15d.
It is formed into an inclined surface that is gentler than the sawtooth portion 15c and faces diagonally downward on the No. 1 item collection section 7 side. and,
Assuming an imaginary line a connecting the upper end of the stay 15a that supports the front end of the rack plate 15b and the rear end of the No. 1 distribution lower plate 7a on the side of the No. 1 object collection section 7, from the rear extension line of this imaginary line a, Also, the first part of the rack plate 15b is placed on the lower side.
