Description

[Detailed Description of the Invention] (a) Industrial field of application The present invention is to mount a grain-clamping and lateral feeding device of a threshing machine on a traveling chassis so as to be orthogonal to the traveling direction of the machine, and to remove the threshing machine's straw. Straw discharging device in a self-propelled threshing machine provided with a straw discharging device for receiving the straw in the conveying direction of the grain culm sandwiching and lateral feeding device and clamping the stocker side and discharging it to the outside of the machine The present invention relates to a device for dropping and discharging straw.

(B) Conventional technology As described above, the threshing machine is mounted on the traveling chassis and the straw discharging device that inherits the straw from the grain-clamping lateral feeding device discharges the straw to the outside of the machine. Threshing machines are well known in the art.

However, when threshing while, for example, advancing or reversing the rice hung on rice trees at a low speed with this conventional self-propelled threshing machine, the posture orthogonal to the discharge direction of straw, that is, the falling posture in that direction, Straws that fall one after another overlap with each other in a misaligned state, and it takes a lot of time to collect and collect them. In addition, since they overlap with each other, sun drying cannot be performed sufficiently.

In addition, there is a drawback that the stab particles that are discharged even if the No. 4 gutter is stabbed by straw are insufficiently collected, resulting in loss.

(C) Problems to be solved by the invention As described above, according to the drop of straw in the conventional self-propelled threshing machine, the recovery work is time-consuming and inefficient, and the sun drying is sufficient. This is not possible, and because the slag particles that are thrown out even when the straw is stabbed are not sufficiently collected by the No. 4 gutter, the present invention eliminates the disadvantages of the conventional method. It is intended to provide the device with a simple structure.

(D) Means for Solving the Problems Therefore, in order to provide the straw dropping device described in the preceding paragraph, the present invention provides a self-propelled threshing machine described in the beginning with a fourth gutter on the straw side. A bag is placed side by side on the outside, and a resistor is placed on the outside of the bag discharge side of the bag to prevent the head side of the straw from hitting and prevent the head side from discharging. It was configured to drop the above in the discharging direction to the ground in such a posture.

(E) Operation With this configuration, when the grain culm is fed to the grain culm pinching and lateral feeding device while the machine is moving forward or backward and is fed horizontally in the handling chamber, the grain culm is handled by the handling barrel built in the handling chamber. Threshing is performed, and the threshing is subjected to a wind separation action to be sorted into 1st, 2nd and 3rd ones, and the 1st one is taken out of the machine and the 2nd one is reprocessed and the 3rd one is removed. The object is discharged to the outside of the machine along with the exhaust air, and the threshed straw is passed from the straw side to the straw discharge device and discharged to the outside of the machine.

At that time, the stab particles that tend to be thrown out even when stabbed into the straw are dropped into the No. 4 gutter and the bag and collected, while the stocker side is pinched and discharged by the straw discharging device. , The tip side of the straw discharged from the straw side hits the resistor and the discharge is blocked, and the straw was discharged in a state orthogonal to the discharge direction When it is turned on, it takes such a posture in a direction substantially orthogonal to the traveling direction of the machine body, that is, a discharging direction, and sequentially falls on the ground.

Further, the impact on the tip side resistor, and by rubbing against the tip side resistor at the time of turning of the stem due to this discharge prevention, the stab particles are forcibly released from the straw and are mainly removed. It falls into the bag and is collected.

(F) Embodiment Hereinafter, the present invention will be described with reference to the accompanying drawings.

(1) is a traveling chassis equipped with a crawler (6), and the thresher (A) is provided on the front side of the traveling chassis (1) so that the grain-and-culp pinching transverse feeding device (2) is orthogonal to the traveling direction of the machine body. The engine (E) is mounted on the rear side, the control section (7) and the paddy storage section (8) are provided, and the grain culm is mounted on the grain culm supply side of the thresher (A). Stands (9) are arranged in series.

Then, the grain culm is clamped from the top of the grain culm mounting table (9) by a grain culm pinching and lateral feeding device (2), which is formed by vertically placing a feed chain (10) and a sandwiching rod (11) vertically. Then, while pushing the guide rail (12) from the upper side, the tip end side is laterally fed to the straw side in the handling chamber (13), during which the grain culm is threshed by the rotation of the handling barrel (14) and the net ( Grains that leak from 15) fall on the rocking sorter disc (16), and are sorted by the sort wind generated by the Karako (17) and the swinging action of the swing sorter disc (16). The number one is from the number one gutter (18) to the frying cylinder (19)
It is lifted up inside and dropped from the main outlet (20) and the sub outlet (21) to the paddy bag supported by the paddy tray (22) and bag hook rod (23) in the paddy storage part (8). It is packed in bags, the second one is returned from the second one trough (24) by the thrower (25) onto the swinging sorting board (16) and is re-sorted, and the third one such as dust is sucked and discharged ( 26) and is discharged to the outside of the machine. Further, the dust-delivered matter from the dust-delivery port (27) opening on the straw side of the handling room (13) is wind-sorted by the sorting wind, and the second one is swing-sorted from the second one (24). 16) The dust is returned to the top by a suction dust collector (26). The threshing-completed straw is passed from the end of the grain-and-sand trapping and lateral feeding device (2) to the straw discharge device (3) consisting of a conveyor belt (28) with a protrusion (28a) and a supporting rod (29), and then the machine body. Being discharged to the outside, the stab particles stuck in the straw (a) at the beginning of the discharge fall into the No. 4 gutter (4) and the bag (33) provided on the outside of the gutter and are collected. It is.

Next, referring to FIGS. 1, 2, and 4, the straw discharge device (3) and the resistor (5) will be described. The driven pulley on the outer end side around which the conveyor belt (28) is wound. A plurality of scraping bars (31) are equally projected on the periphery of (30), and the support rod (29) below the conveyor belt (28) sandwiches the operating side of the conveyor belt (28). Two rods are arranged side by side and the tips are connected to form one, and the tip side has a steeply inclined portion (29a) and a gently inclined portion (29a) that descend obliquely as well understood from FIG. ) Has been formed.

Further, the resistor (5) is formed by bending a rod-shaped one in a rear view, and the base is detachably attached to the attachment metal (32) attached to the body part on the straw side, The hanging part is used as a blocking part (5a) that gives a blocking effect to the tip side of straw (b). 4
The catch bag (33), which is provided on the outside of the number trough (4) and is detachable in parallel, is positioned on the outside of the straw discharge side of the bag (33). The front and rear and left and right relational positions of the straw discharging device (3) are shown in the respective figures (FIG. 1, FIG. 2, FIG. 4).
(Fig.).

Therefore, the conveyor belt (28) of the straw discharging device (3)
With the support rod (29), the root side of the straw (a) is pinched and discharged at the beginning of discharge in a state orthogonal to the discharge direction (b), as shown in Fig. 4. When threshing while advancing in the direction of arrow (c), the tip side hits the blocking part (5a) of the resistor (5) and the discharge is blocked, but the stocker side is still pinched and discharged. The straw (a) is forced to change its stem orientation and the discharge direction (b)
Then, it takes such a posture and falls on the ground one after another, and becomes a juxtaposed state.

Then, at the time of this fall to the ground, the stock root side of the straw (a) is scraped off by the scraping rod (31) provided on the driven pulley (30), and suddenly along the steep slope (29a). At the same time, it falls to promote the above-mentioned posture change, and then to make the root side, which is heavier than the tip side, be received by the gently sloping part (29b) so that it does not drop to the ground earlier than the tip side. The whole culm will be grounded.

Further, the stab particles that have not fallen from the straw (a) due to the abutment of the blocking portion (5a) of the resistor (5) on the tip side are released from the straw (a), and at the same time Then, when the straw (a) is diverted to the culm, the tip side is blocked (5
By rubbing with a), the stuck particles are forcibly detached from the straw (a) and mainly fall into the bag (33) to be collected.

In the embodiment, the scraping bar (31) is provided so as to project from the peripheral edge of the driven pulley (30), but a star wheel or the like may be additionally provided instead.

Further, if the amount of protrusion of the conveyor belt (28), the support rod (29) and the resistor (5) constituting the straw discharging device (3) to the outside of the machine can be adjusted respectively, the straw ( It is possible to quickly respond to conditions such as the long and short rods of b), and to adjust the posture change of the straw (b) to an appropriate one.

(G) Effect of the Invention As is clear from the above description, the present invention is the self-propelled threshing machine described at the beginning, in which a bag is provided outside the No. 4 gutter on the straw side. On the outside of the straw discharge side of the bag, a resistor is installed on the outer side of the straw discharge side to block the discharge of the tip side, and the stocker side precedes, and the straw is discharged to the ground in that posture. Since it is characterized by dropping it, when threshing while advancing or reversing the aircraft, the root side is pinched by the straw discharging device and discharged, but the tip side is a resistor. The straw that had been discharged in a state orthogonal to the discharge direction by hitting against the direction is forced to change the direction of the stem and the direction substantially perpendicular to the traveling direction of the aircraft, that is, the discharge direction. The posture is so low that it falls on the ground one after another and is in a juxtaposed state, so that the straw recovery work is efficient. And will but also solar drying performed sufficiently.

Further, the impact on the tip side resistor, and by rubbing against the tip side resistor at the time of turning of the stem due to this discharge prevention, the stab particles are forcibly released from the straw and are mainly removed. As it falls into the bag, it can be collected sufficiently and loss can be eliminated.

As a result, it was possible to provide a straw dropping device with a simple structure that can eliminate the drawbacks of the prior art.
