A first leaking portion for allowing the sorting object supplied from the upper side to leak,
A second leak portion that is located below the first leak portion and that allows the sorting object leaked by the first leak portion to leak toward the recovery portion first; Adjusting means for adjusting the leakage capacity of each of the lower part and the second leakage part,
A threshing apparatus configured to adjust the leakage capacity of the first leaking portion and the second leaking portion to be larger as the grain stalk feeding amount is larger based on the information of the grain stalk feeding amount detecting means. The present invention relates to a sorting control device.

[0002]

2. Description of the Related Art In the above-mentioned sorting control device of a threshing device, conventionally, under the same field conditions, the faster the vehicle speed is, the larger the amount of harvested cereal culm is. Therefore, the amount of cereal culm supplied to the handling room is detected by the vehicle speed. Based on the detection results, the larger the cereal stalk supply amount, and the same adjustment amount for the change in the unit amount of the cereal stalk supply amount, each of the chaff sheave as the first leak lower portion and the Glen sheave as the second leak lower portion The opening capacity (or slide sheave amount) was adjusted to adjust the respective leaking abilities.
That is, by adjusting the opening of the chaff sheave to the open side or the closed side in accordance with the increase or decrease of the vehicle speed (grain culm supply amount),
The amount of the sorting object on the chaff sheave is gradually reduced from the front end to the rear end of the chaff sheave so as to exist to the rear end, and a predetermined amount of the sorting object exceeds the rear end of the chaff sheave. Was to be recovered. Thereby, for example, when the sorting target object on the chiff sheave does not exist before reaching the rear end side of the chaff sheave, an increase in the mixing of straw waste and the like into the leakage from the chaff sheave, and conversely, The so-called third loss (grain release outside the machine), which occurs when the amount of the second object is excessively increased due to an excessive amount of the object to be sorted, or a large amount of the second object collected on the chaff sieve. The problems such as damage to the grains caused by the re-sorting and re-sorting are prevented.

[0003] In addition, by adjusting the opening of the grain sieve in accordance with the increase or decrease in the vehicle speed (grain culm supply amount), the leakage from the chaff sheave increases or decreases in accordance with the increase or decrease in the vehicle speed (grain culm supply amount). In addition, an appropriate amount of the object to be sorted is always present on the grain sieve. In this way, it is possible to prevent the waste from the chaff sheave from leaking from the chaff sheave on the Glen Sheave into an undersized (or nonexistent) state from being mixed most into the collected material. Sorting accuracy was ensured.

[0004]

However, in the above-mentioned conventional means, although the adjustment conditions required for the chaff sheave opening and the adjustment conditions required for the Glen sheave opening are different as described above, the double opening is not possible. The control of the degree was not controlled so as to be optimal for each requirement while relating the adjustment of the degree. In other words, in the adjustment of the opening degree of the chaff sheave, it is required that an appropriate amount of the sorting object be present on the chaff sheave and that the second recovery material is increased more than necessary and the third loss is reduced as much as possible. (Thus, the opening of the chaff sheave is not adjusted to the close side more than necessary.) In contrast, in the adjustment of the opening of the Glen sheave, it is required that the mixing of straw waste and the like into the collected material is never generated. (Accordingly, the Glensheave opening is not adjusted to the open side more than necessary). Therefore, for example, when the opening of the chaff sheave and the opening of the Glen sheave are adjusted under the same adjustment condition, when the opening of the chaff sheave is opened in response to an increase in vehicle speed (grain culm supply amount), The opening of the grain sieve becomes too wide, and the straw waste that leaked the chaff sieve also leaks the grain sieve as it is and mixes into the collected material at the same time, while responding to the decrease in vehicle speed (grain culm supply). When the chaff sheave opening is closed, the Glen sheave opening is too closed, and there is a problem that the collection efficiency of the collected material is extremely reduced most.

An object of the present invention has been made in view of the above circumstances, and it is an object of the present invention to adjust the leakage capacity (for example, the opening degree of the chaff sheave) of the first leakage part and the leakage ability of the second leakage part. (For example, adjustment of the Glen sheave opening degree) to maintain a predetermined relationship with the adjustment of the rocking separation plate that matches the leakage ability of both the lower and lower parts in an appropriate state.

[0006]

Characteristic feature of the sorting control device for threshing apparatus according to the present invention, in order to solve the problems], said adjustment means, said first
Leakage capacity adjustment range for changes in the supply of cereal stalks at the bottom
The leakage capacity at the minimum side of the enclosure
Minimum position of leakage capacity adjustment range for changes in culm supply
Large west than Moshita capacity in, and, from the adjustment amount of the culms supply amount of the unit amount of the second leakage under capacity leakage of the lower adjustment amount of the first leakage bottom of leakage under capacity for variation Is also configured to be large.

[0007]

According to the characteristic configuration of the present invention, the change in the supply amount of cereal stalks.
1st lower part at the minimum position of the leakage capacity adjustment range
Ability to control the leakage capacity against changes in cereal stem supply
Larger than the leakage capacity of the second leakage part at the minimum position of the range
In this state, the amount of adjustment of the leakage capacity of the first leaky portion with respect to the change amount of the unit amount of the grain culm supply is made larger than the amount of adjustment of the leaky ability of the second leaky portion with respect to the same change amount. Grain culm supply
The first leak in the entire range of leak capacity adjustment to changes in volume
The leakage capacity of the lower part is larger than that of the second part.
In addition, for example, in the case where the supply amount of cereal stalk is increased, when the leaking capacity of the first leaking part is increased to cope with this increase, the leaking capacity of the second leaking part does not become so large, As a result, it is possible to prevent the incorporation of straw waste and the like into the collected material most, while appropriately performing the leaking treatment for the increased grain culm supply amount. On the other hand, when the supply of cereal stems decreases, the leakage capacity of the first leaking part is reduced to cope with this decrease, but the leaking capacity of the second leaking part does not become so small. While appropriately responding to the decrease in the supply of cereal stalks, the amount of collected material is not extremely reduced.

[0008]

Thus, the sorting ability of the swing sorting plate as a whole is maintained in an appropriate state in accordance with the difference in the adjustment condition of the leaking ability required for each of the first leaking part and the second leaking part. Thus, it is possible to obtain a sorting control device for a threshing device that can achieve both sorting accuracy and ensuring collection efficiency.

Although not described in detail, the second articles collected from the second collection section 23 are returned to the handling room A and are handled again.

[0015] As shown in FIG.
A plurality of strip-shaped members 19a, 20a juxtaposed in the processing object transfer direction (the left-right direction in the drawing) are provided on each of the Glen sheaves 20 with respect to the left and right side plates 21 with the upper side as a fulcrum. Each of the operation rods 24 and 27 pivotally attached to the lower end of each of the band plate-like members 19a and 20a is pushed and pulled in the front-rear direction, so that each of the band plate-like members on the chaff sheave 19 side. The interval t1 of 19a (may be abbreviated as chaff sheave opening in the following description) and the interval t2 of each strip 20a on the Glen sheave 20 side (may also be abbreviated as Glen sheave opening in the following description) are respectively provided. It is configured so that it can be changed and adjusted.

The end of the operating rod 24 on the side of the chaff sheave 19 is locked to one end of a first arm 29 which rotates around a horizontal axis Q provided at a center position, and the other end of the first arm 29. Is locked in a long hole provided on the upper side of a plate-shaped second arm 28 that rotates around a horizontal axis P provided at a substantially central position. On the other hand, the end of the operation rod 27 on the side of the Glen Sheave 20 is locked at a position below the second arm 28. Further, an electric motor M1 for adjusting the chaff sheave opening t1 and the Glen sheave opening t2 is provided, and the linkage mechanism 2 driven by the electric motor M1 is provided.
5 and the lower end of the second arm 28
6 are interlocked. In the figure, reference numeral 30 denotes a spring for urging the chaff sheave opening t1 and the Glen sheave opening t2 to return to the closing side, and S2 denotes an operation amount of the linkage mechanism 25 by the electric motor M1 as information of the chaff sheave opening t1 and the Glen sheave opening t2. This is a potentiometer-type opening degree detection sensor that detects an angle.

With the above arrangement, when the electric motor M1 is rotated in the forward and reverse directions, the second arm 28 is rotated in the forward and reverse directions around the horizontal axis P, so that the operation rods 24 and 27 are simultaneously pushed and pulled. The chaff sheave opening t1 and the Glen sheave opening t2 are changed by the operation. By the way, the more the chaff sheave opening t1 or the Glen sheave opening t2 is operated to the opening side, the larger the amount of the sorting object leaking through the chaff sheave 19 or the Glen sheave 20 per unit time. Therefore, the transmission mechanisms 24 to 29 for transmitting the operation of the electric motor M1 to the operation of changing the chaff sheave opening t1 and the Glen sheave opening t2 are provided by the two operating rods 2.
4, 27, the link mechanism 25, the release wire 2
6, the first arm 29 and the second arm 28.

As shown in FIG. 1, a control device H using a microcomputer is provided. The control device H receives signals from the grain stick detection sensor S0, the vehicle speed sensor S1, and the opening degree detection sensor S2. At the same time, the control device H outputs a drive signal to the electric motor M1 for adjusting the opening.

Using the control device H, the electric motor M1, and the linkage mechanisms 24-29, the higher the vehicle speed (ie, the larger the grain culm supply amount) based on the information from the vehicle speed sensor S1, the more the vehicle speed. The chaff sheave 19 and the Glen sheave 20 are arranged such that the opening degree (that is, the leakage capacity) of the chaff sheave 19 and the Glen sheave 20 increases.
Adjusting means Z configured to adjust the leaking capacity is configured, and the adjusting means Z is provided at a position on the minimum side of the leaking capacity adjusting range with respect to the change in the vehicle speed (that is, the grain culm supply amount) .
The leakage capacity of the chaff sheave 19 is adjusted to the above-mentioned leakage capacity adjustment range.
Greater than the leakage capacity of the Glen Sheave 20 at the minimum position
The amount of adjustment of the chaff sheave opening t1 of the chaff sheave 19 with respect to the variation of the unit amount of the vehicle speed (grain culm supply amount) is determined by the Glen sheave opening t2 of the Glen sheave 20.
Is configured to be larger than the adjustment amount.

That is, as shown in FIG.
The distance b from the position of the horizontal axis P of the second arm to the position where the first arm 29 is locked is the distance between the position of the horizontal axis P of the second arm 28 and the operating rod 2.
7 is set to be larger than the distance a to the locking position, the moving amount of the operating rod 24 on the chaff sheave 19 side is less than that of the Glensheave 2 for the same operating amount of the electric motor M1.
The movement amount of the operation rod 27 on the 0 side is larger than the movement amount of the operation rod 27. Therefore, the chaff sheave opening t1 changes more than the Glen sheave opening t2. Also, the chaff sheave opening t
The opening degree t10 of the fully-closed 1 (closed position on the opening / closing operation movable range) is the same as the Glensheave opening degree t2.
Since it is set to be larger than 20, the chive sheave opening t1 is equal to the Glen sheave opening t over the entire range of the opening / closing operation.
It does not become smaller than 2 (see FIG. 7). The upper limits of the two openings t1 and t2 are also the limit openings t1g and t1, respectively.
2 g is set.

Next, the operation of the control device H will be described with reference to the flowchart shown in FIG. When the control is started, first, the handling room A is controlled based on the information of the grain stick detection sensor S0.
It is detected whether or not there is a grain culm therein. When the grain rod is supplied, the chaff sheave opening t1 corresponding to the detected vehicle speed value is set with the limit opening t1g (or t2g) as an upper limit.
The target value of (or the Glen sheave opening t2) is calculated (see FIG. 7). After the target value of the chaff sheave opening t1 (or the Glen sheave opening t2) is determined, the electric motor M1 is driven so that the opening reaches the target value.

On the other hand, if it is not in the feeding state, it is checked whether or not a set time has elapsed since the turning rod detection sensor S0 changed from ON to OFF. That is, when there is no object to be sorted from the handling room A when the harvesting operation is not basically being performed, the target values of the chaff sheave opening t1 and the Glen sheave opening t2 are the openings t10 and t20 at the time of the full closing. However, immediately after the harvesting operation is completed, the stalk remains in the handling room A for a while, so that the leakage of the sorting object to the sorting device B does not stop immediately, but gradually with time. The state will decrease. Therefore, after the mowing operation is completed, the target values of the chaff sheave opening t1 and the Glen sheave opening t2 are gradually changed until the set time elapses.

[Alternative Embodiment] In the above embodiment, the amount of adjustment of the opening of the chaff sheave 19 with respect to the amount of change of the unit amount of the vehicle speed (that is, the amount of grain culm supplied) is larger than the amount of adjustment of the opening of the Glen sheave 20. Mechanical means for transmitting the same amount of operation by one electric motor M1 so as to provide different amounts of adjustment for the respective opening degrees of the chaff sheave 19 and the Glen sheave 20. Although constituted by the transmission mechanisms 24-29, it is not limited to this means. FIG. 8 shows an example of another adjusting means Z configured so that the adjustment of the opening of the chaff sheave 19 and the adjustment of the opening of the Glen sheave 20 are separately performed by separate electric motors M1a and M1b. That is, chaff sheave 1
In order to adjust the opening of the swing arm 9, the linkage mechanism 25a driven by the electric motor M1a and the free end of the swing arm 28a are interlocked and connected by a release wire 26a. Is locked at the end of the operating rod 24 on the side of the chaff sheave 19. Reference numeral 30a denotes a spring for urging the chief sheave opening t1 to return to the closing side, and S2a denotes a potentiometer type chief sheave opening detection sensor for detecting the operation amount of the link mechanism 25a as information of the chief sheave opening t1. Meanwhile, Glen Sheave 2
For the adjustment of the opening of 0, exactly the same means as the adjustment of the opening of the chaff sheave 19 is provided. That is, the linkage mechanism 25b driven by the electric motor M1b and the free end of the swing arm 28b are interlocked and connected by the release wire 26b, and the other operation of the Glen sheave 20 at the free end of the swing arm 28b is performed. The end of the rod 27 is locked. Reference numeral 30b denotes a spring for urging the Glen sheave opening t2 to return to the closing side, and S2b denotes a potentiometer-type Glen Sheave opening detection sensor for detecting the operation amount of the linkage mechanism 25b as information on the Glen sheave opening t2.
The two electric motors M1a and M1b are individually driven by the control device H.

Further, in the above embodiment, in order to adjust the leaking ability of each of the first leaking portion 19 and the second leaking portion 20, a plurality of strip plates in which the two leaking portions 19, 20 are juxtaposed in parallel are arranged. It is configured by a mechanism composed of the strip-shaped members 19a and 20a, and the interval between them, that is, the opening degree is adjusted.
a, 20a instead of adjusting the opening degree, for example,

May be. Further, as another leaking capacity adjusting means, a mesh-shaped chaff sheave having a constant opening per unit area or a sliding type shielding plate which protrudes and retracts on the upper side of the Glen sheave is provided, so that the vehicle speed is high (that is, grain culm supply). Large amount)
Means may be used in which the shielding plate is extended more so that the entire leakage area is increased to increase the leakage capacity.

In the above embodiment, the vehicle speed sensor S1 is used as the grain culm supply amount detecting means for detecting the grain culm supply amount to the handling room A.
Alternatively, for example, the swing angle of the contact piece 15 of the grain stick detection sensor S0 may be detected, and the grain stem supply amount may be determined from the magnitude of the swing angle.
