The present invention relates to a thresher adapted to perform a leak screening with a provided grain sieve.

[Conventional technology]

In this type of thresher, as shown in Japanese Patent Application No. 1-5688 filed by the applicant of the present invention, the grain pan can be slidably moved in a predetermined range in the front-rear direction with the front grain pan fixed in position. A technique has been proposed in which a rear Glen Pan is connected to the front and the rear, and the rear Glen Pan is slid to open and close according to the amount of threshed material.

[Problems to be Solved by the Invention]

However, the above-mentioned conventional technology only mentions the function of opening and closing the rear Glen pan, and it has not been clarified how to open and close the rear Glen pan according to the amount of the processed material.

An object of the present invention is to provide a thresher capable of effectively utilizing a slide opening / closing type Glen pan.

[Means for solving the problem]

In order to achieve the above object, the present invention, in the threshing machine described at the beginning, the Glen pan, the front Glen Pan fixed position, in the state of overlapping the front end side to this front Glen Pan, the overlapping length It is configured by a rear Glen pan that can be slid back and forth within a predetermined range while being changed, and the front and rear length of the specific gravity difference sorting operation unit of the Glen pan is changeably adjustable, and the front end side of the Glen sieve is the rear Glen pan. In a predetermined range to overlap relative to the front and rear from the lower side, as the front-rear length of the specific gravity difference sorting action portion is extended, the front-back length of the leakage leakage action portion of the Glen sieve is shortened, As the front-rear length of the specific gravity difference selecting portion is shortened, the front-rear length of the leakage selecting portion is extended, and a single grain culm is sent to the handling chamber including the handling barrel. A means for detecting the amount of fluctuation per unit time was provided, and this detection means automatically moved the rear grain pan forward in response to the detection of an increase in the amount of grain culm, and detected a decrease in the amount of grain culm. Due to this, the automatic control mode in which the detecting means and the rear Glen pan are automatically linked to the state in which the rear Glen pan is automatically moved rearward, and regardless of the variation detection information of the grain culm amount by the detecting means. It is characterized in that it is configured to be able to appear by selectively selecting a fully open mode in which the fully opened state in which the rear part of the pan is moved to the frontmost position is selected.

Further, it is convenient if the thresher is provided with means for changing and setting the amount of forward movement of the rear Glen pan in the fully open state in the automatic control mode.

[Work]

(A) When the amount of processed material sent to the Glen pan consisting of the front and rear Glen pans is large, the rear Glen pan is slid forward to shorten the front-rear length of the specific gravity difference selecting portion of the Glen pan. Increase the front and back length of the leakage screening section of the Glen Sieve following the Glen Pan to increase the leakage area.

As a result, the processed product can reach the gren sieve side from the gren pan side quickly, and the grains leaking from the gren sieve can be increased, so that the sorting ability can be improved.

[B] When the amount of the processed material is small, the rear Glen pan is slid rearward to extend the front-rear length of the specific gravity difference sorting operation unit of the Glen pan, and the front-rear length of the leakage sieve operation unit of the Glen sieve is shortened. To reduce the leakage area.

As a result, it is possible to sufficiently sort the processed products by the specific gravity difference with the Glen pan, and it is possible to prevent the dust such as cut straw existing in the upper layer of the processed product layer from leaking due to the specific gravity difference selection with the Glen pan, and the selection ability is improved. Can be improved.

[C] Since the detection means can detect a change in the amount of grain culm sent to the handling room, that is, a change in the amount of processed material per unit time, the Glen pan is opened / closed according to the detection result of the detection means. Then, by setting the automatic control mode for automatically adjusting the leakage area of the Glensieve, it becomes possible to automatically perform the above-mentioned good selection.

Further, [d] In addition to the automatic control mode, the full-open mode in which the rear Glen pan is fully opened can be selected independently of the detection means, so that it is difficult to be selected, for example, during wet threshing. It will be in a suitable state when sorting the processed products.

Further, according to the configuration of claim 2, the movement amount at the time of full opening in the case of wheat containing a large amount of cut straw is 2 / when the movement amount at the time of full opening of the rear grain pan in the case of [e] rice is 2 /.
It becomes possible to select the leaking area of the greasive which has the best sorting performance according to the type of the threshing target, such as setting to 3.

〔The invention's effect〕

Therefore, in the thresher according to claim 1, the sorting performance is further improved by the above-mentioned actions [a] and [b], and the control is automatically performed by [c] and [d]. Compared with the case of opening and closing the Glen pan artificially, the labor and time to constantly watch the increase and decrease of grain culm can be saved, and wet threshing etc. can be handled, so workability and operability can be improved and rational. It was possible to improve the sorting performance.

And in the thresher of Claim 2, said action [e]
As a result, the above-described effect according to the configuration of claim 1 can be achieved regardless of the type of threshing target grain culm.
