Description

[Detailed Description of the Invention] [Industrial field of application] The present invention forms a transport passage for grain stems that are conveyed in a horizontal posture by a feed chain in a handling chamber, and a handling barrel is mounted in the handling chamber. However, the present invention relates to a threshing device which is provided with a receiving net under the threshing device.

[Prior Art] This type of threshing device threshes the grain culms that have been held and conveyed in the handling chamber by the feed chain by the handling cylinder, and allows the single grained rice to leak downward through the receiving net, Only the remaining waste straws are carried out of the handling chamber by the feed chain and conveyed to the waste straw processing section.

[Problems to be solved by the invention]

However, in the threshing device described above, since the transportation path of the grain culm formed in the handling room is narrow, the grain culm is conveyed in a state of being laid sideways, so that the grain can be crushed even though it is singularized. It often happens that the shavings are stabbed by the discharged straw and are carried out of the handling room together with the grain culms, and are conveyed to the discharged straw processing section. This is the so-called sticking loss.

Therefore, in order to suppress the occurrence of stab loss, conventionally, for example, as disclosed in Japanese Patent Laid-Open No. 61-173716, the resistance is reduced by suppressing the grain culms conveyed in a sideways posture from the lower side. It is known that the rice seeds are removed and the paddy rice is removed from the grain culms by feeding the grain culms to separate them.

However, in the case of this structure, since the grain is merely restrained from the lower side to the upper side, the posture of the grain culm does not change so much, and the grain culm that is stuck between the grain culms is the grain culm. Could not be removed sufficiently.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a threshing device capable of reducing the occurrence of such piercing loss and recovering the single-grained rice more efficiently. .

[Means for solving problems]

In order to achieve the above-mentioned object, the characteristic configuration of the present invention is to form a conveying passage for a grain stalk that is conveyed in a laid-down posture by a feed chain in the handling chamber, and axially mount the handling barrel in the handling chamber. It is a threshing device that is stretched over the lower part, and a pressing member that presses downward from above the discharging straw that is being carried and carried out from the handling chamber is provided at the rear of the handling chamber in a cantilever shape facing rearward. In point.

The operation and effect of this characteristic configuration are as follows.

[Action]

That is, at the same time as the discharge straw being held and conveyed by the feed chain is carried out of the handling chamber, it is pressed downward from above by the pressing member provided at the rear portion of the handling chamber. Then, the sheet is conveyed backward while being bent downward. When the discharge straw reaches the rear end of the cantilevered pressing member and is released from the pressing,
The elastic restoring force of the culm of the discharged straw jumps up at once, and the discharged straw is dislodged by the vibration at that time, or the stabbed paddy is shaken off from the discharged straw due to the inertia of the paddy.

[Effect of device]

As a result, the pressing member at the rear part of the handling chamber presses the discharged straw being held and conveyed downward from above, and the discharged straw is pushed open from its rear end and vibrates when it jumps up, and the paddy pad is shaken off sufficiently. By the removing action, it becomes possible to efficiently collect the paddy by reducing the sticking loss, as compared with the case where the sticking paddy is removed by simply giving the transfer resistance to the discharged straw during the carrying and holding.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

As shown in Fig. 1, the threshing part (A) for threshing the grain culms that has been conveyed while being held in a horizontal position by the feed chain (1) and the sandwiching rail (7) and the threshing part (A) leaks. An oscillating sorting part (B) for sorting the processed products into the first product, the second product and straw waste, and a recovery part (C) for recovering the sorted first product and the second product. At the same time, a Karako (2) is provided in front of the collecting section (C) and a dust-exhausting fan (3) is provided behind the threshing section (A) to form a combine-mounted thresher.

The threshing unit (A) includes a belt type handling drum (5) in the handling chamber (4), and a receiving unit for leaking the processed material along the lower path portion of the belt type handling barrel (5). It is constructed by stretching a net (6).

As shown in FIGS. 2 and 3, the belt type handling cylinder (5) has a driving pulley (8) and a driven pulley (9) mounted on the handling chamber (4), and both pulleys (8) ), (9) is a belt-shaped endless belt (10) is wound, the grain culm being held and conveyed inserted from the handle (4a), the direction away from the feed chain (1) It is designed to handle the lower path portion that turns to. Notches (10a) are formed on the outer peripheral surface of the punching belt (10) at regular intervals in the circumferential direction to facilitate deformation.

The swing selection section (B) has a Glen pan inside the swing case (11).
(12), Glen Sieve (13), Upper and lower two-stage Straw rack (1
4), (15), etc. are incorporated, and the rocking case (11) is connected to the eccentric cam mechanism (16) on the machine side, and the whole rocks together with the rocking case (11). I am trying to move. Supplementally, the leaked substances leaked from the receiving net (6) and the non-leaked substances discharged from the dust inlet at the rear of the handling room (4) are collected into the Glen pan (12), the Glen sieve (13), and the top and bottom. The two-stage straw racks (14) and (15) are oscillated and transferred rearward while selecting leakage. Then, the leaked substance that leaked through the Glen Sieve (13) was the first one, and the non-leaked substance that was released from the rear end without leaking was the second one and dropped into the recovery part (C), respectively. Then, the non-leakage material discharged from the rear end of the lower straw rack (15) is discharged outside the machine as straw dust.

The recovery unit (C) is a first product recovery unit (17) for recovering the first product dropped and supplied from the swing selection unit (B) and a second product recovery unit (18) for recovering the second product. Consists of. The secondary product recovered by the secondary product recovery unit (18) is sent upward by the thrower (19), and is swinging and sorted from the secondary return port (20) opening on the right side plate.
(B) Reduced to above. Incidentally, (21) is a guide plate for guiding down the second article dropped from the second article return port (20) onto the swing selection section (B), and swings the swing case (11). With it, it is made to freely vibrate up and down.

In the thresher, in the rear part of the handling room (4), the handling room (4)
A pressing member (22) that presses the discharged straws that are being carried out from and being held and conveyed downward from above is provided in a cantilever shape facing rearward. Next, the function of the pressing member (22) will be described.

The grain culm that has been conveyed while being laid sideways by the feed chain (1) and the holding rail (7) is threshed by the handling action of the belt type handling cylinder (15) in the handling room (4), and the waste straw is discharged. Becomes At this point, the discharged straw is stuck with some husks that have become single grains. Next, the discharged straw is carried out from the handling chamber (4), and at the same time, the stocker side thereof is pressed from above by the pressing member (22) and bent downward. The deflection of this straw is
Since the pressing member (22) is lower toward the rear end, the pressing member (22) becomes larger toward the rear end. When the discharge straw reaches the rear end of the pressing member (22) and is released from the pressing, the elastic restoring force of the culm jumps up at once, and the vibration at that time shakes off the stabbed paddy.
