Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a straw discharging device for a self-propelled threshing machine, in which the threshing machine is equipped with a grain-and-gripping transverse feeding device of the threshing machine orthogonal to the traveling direction of the machine. , A conveyor belt and a supporting rod are vertically arranged on the straw side of the machine, and the straw is inherited in the conveying direction of the grain-clamping lateral feeder, and the stocker side is clamped and discharged to the outside of the machine. It has a structure provided with a straw discharging device.

[0002]

[Prior Art]

 As mentioned above, self-propelled thresher that discharges straw to the outside of the machine by the straw discharge device that has the threshing machine mounted on the traveling chassis and inherits the straw from the grain stalk sandwiching and lateral feeding device is well known in the art. However, for example, when threshing rice that has been hung on rice trees while moving forward or backward at low speed with this conventional self-propelled threshing machine, it falls in the posture orthogonal to the discharge direction of straw, that is, the posture in the forward direction. The straws that fall down one after another in this way are misaligned, and it takes a lot of time and effort to collect and stack them. In addition, they overlap and cannot be dried in the sun.

[0003]

[Problems to be solved by the device]

 As described above, according to the conventional straw discharging device for the self-propelled threshing machine, the straw is dropped in such a posture in the traveling direction of the aircraft, and the ones falling one after another are displaced. Since overlapping collection work is very time-consuming and inefficient, and it is not good even in the case of sun-drying, it is possible to eliminate the above-mentioned conventional drawbacks. I devised a prototype of the discharge device and filed an application for Japanese Patent Application No. 2-109153. However, in the subsequent test, the straw discharge device of this application did not properly perform the turning action of straw. Moreover, the culm length was uneven with long and short lengths, and the discharged straw was further disturbed and the intended purpose could not be achieved. Therefore, the applicant has made further intensive studies and, after a trial test, has come up with a device for exhausting straw that meets the purpose, and therefore, an improved version thereof is provided here.

[0004]

[Means for Solving the Problems]

 Therefore, in order to provide an improved version of the straw discharging device which meets the above-mentioned purpose, in the self-propelled threshing machine described at the beginning, in the outside of the No. 4 gutter on the straw side of the machine, A resistor is installed to prevent the tip side from discharging, so that the stocker side precedes, and the support rod is bent and extended obliquely downward on the upper side of the conveying action side end portion of the conveyor belt. The length from the bent portion to the end of the conveyor belt on the conveying side and the length from this end to the extended end of the support rod are the same or the length from this end to the extended end of the support rod. The length is set to be longer than the length from the bent portion of the support rod to the end of the conveyor belt on the conveyor side.

[0005]

[Action]

 With this configuration, when the grain culm is fed to the grain culm sandwiching and traversing device while the machine is moving forward or backward and is fed laterally in the handling chamber, the grain culm is threshed by the handling barrel built into the handling chamber. The grain removal is subjected to a wind-selecting action and sorted into 1st, 2nd and 3rd ones, the 1st one is taken out of the machine, the 2nd one is reprocessed and the 3rd one is exhausted. At the same time, the threshed straw that is discharged outside the machine is inherited from the straw side to the straw discharge device, discharged to the outside of the aircraft, and the sludge that is about to be discharged together with the straw is 4 After being dropped into the guard trough and collected, the stocker side is pinched by the straw discharge device and discharged, but the tip side is discharged by a resistor that is orthogonal to the discharge direction. The discharged straw is discharged so that the direction of its stems is gradually changed, and the stockholder side supports it. When it reaches the bent part of the rod, it is released from the transporting action of the transport belt and is rapidly slid on it while being received by the support rod that moves diagonally downward, the stock base descends to the outer side position of the aircraft and It will be forced to turn to such a posture in a direction that is almost orthogonal to the direction of discharge, that is, it will be arranged in order on the ground.

【Example】

 The present invention will be described below with reference to the accompanying drawings. (1) is a traveling chassis provided with a crawler (6), and a thresher (A) is provided on the front side of the traveling chassis (1). The grain culm sandwiching and lateral feeding device (2) is mounted so as to be orthogonal to the traveling direction of the machine body, the engine (E) is placed on the rear side, and the control unit (7) and the paddy storage unit (8) are installed. A grain culm mounting table (9) is continuously provided on the grain culm supply side of the thresher (A).

[0007] Then, the grain culm is placed on the grain culm mounting table (9) and fed to a grain culm sandwiching and lateral feeding device (2) in which a feed chain (10) and a sandwiching rod (11) are vertically opposed to each other. While holding the root side and pressing it with the guide rail (12) from the upper side, the tip end side was laterally fed to the straw side through the handling chamber (13), during which the grain culm was rotated by the handling barrel (14). The threshing that has been threshed and leaked from the net (15) falls on the rocking sorter (16), and the sorting wind and the rocking sorter (16) blown up by the Karako (17). Sorted by the swinging action, the No. 1 grain is lifted from the No. 1 grain trough (18) in the fried cylinder (19) and dropped from the main outlet (20) and the auxiliary outlet (21) to store paddy. Part (8) is packed in a paddy bag supported by a paddle stand (22) and a bag-hanging rod (23), and the second one is the second one (24) to the thrower ( 25) is returned to the rocking sorting board (16) and re-sorted, and the third object such as dust is sucked by the suction dust collector (26) and discharged to the outside.

Further, the dust-delivered matter from the dust-delivery port (27) opening on the straw side of the handling room (13) is selected by the sorting wind, and the second one swings from the second-men's trough (24). The dust returned to the sorting board (16) is discharged to the outside by the suction dust extractor (26), and the threshed straw is projected (28a) from the end of the grain stalk sandwiching and lateral feeding device (2). The conveyor belt (28) and the support rod (29) are vertically arranged to be taken over by the straw discharge device (3) and discharged to the outside of the machine. The stab particles stuck in the straw (a) are dropped and collected in the No. 4 gutter (4) and the bag (30) provided outside it.

Next, referring to FIG. 1, “FIG. 2” and “FIG. 4” regarding the straw discharging device (3) and the resistor (5), the conveyor belt (28) is located at the outer end side. It is hung around the driven pulley (31) and cooperates with the support rod (29) as described above to convey the straw (a) to the outside of the machine body, but under the conveyor belt (28). The side support rod (29) has two rods arranged side by side so that the rear side (a) is higher than the front side (b) so as to sandwich the conveyor belt (28), and the front ends thereof are connected. As shown in FIG. 1, in particular, as shown in FIG. 1, the driven pulley (31) is greatly folded downward from the upper side of the conveying action side end portion (0) immediately below the rotation axis center of the driven pulley (31). A steep slope (29a) is formed by extending a curve, and the steep slope (29a) has a gentle slope from the extending end (Q). (29b) is extended so as to form a length (M) from the bent portion (P) of the support rod (29) to the conveying action side end portion (0) and this end portion (0). To the extension end (Q) of the support rod (29) to the support rod (29) are the same or the length (L) is set to be larger than the length (M). ing. Reference numeral (32) denotes a wrapping prevention plate for the straw (a) which is welded to the support rod (33) which supports the driven pulley (31).

The resistor (5) is a rod-shaped member that extends in the same direction as the conveyor belt (28) and is then bent downward so that the base is located on the body part on the straw side. It is detachably attached to the attached mounting metal (34), and the hanging portion is used as a blocking portion (5a) for blocking the tip side of the straw (a), and is attached to the outside of the No. 4 gutter (4). It is located outside the receiving bag (30) provided in a side-by-side removable manner, and the front-rear and left-right relational positions of the resistor (5) and the straw discharge device (3) are respectively shown in the "FIG. 1". It is done as shown in "Fig. 2" and "Fig. 4".

Accordingly, the conveyor belt (28) and the supporting rod (29) of the straw discharging device (3) pinch the root side of the straw (a), so that the discharge direction ( It is discharged in a state that it directly intersects with (b), but when threshing while advancing in the direction of arrow (c), for example, as shown in FIG. Although the discharge is blocked by 5a), the stocker side is still pinched and discharged, and the straw (a) is discharged so that the direction of the stems of the straw is gradually changed, and the stocker side of the straw (a) is discharged. When it reaches the bent portion (P) of the supporting rod (29), it is released from the conveying action of the conveyor belt (28) and is rapidly received by the steeply inclined portion (29a) which is slanted downward, and quickly slides on it. Will be lowered to the outer side position of the aircraft, and the straw (a) will ), It is forcibly changed to such a posture, and it falls to the ground one after another and becomes a juxtaposed state. Then, at the time of this fall to the ground, the root side of the straw (a), which is heavier than the tip side, is in a state of being received by the gentle slope (29b) so that it does not fall to the ground earlier than the tip side. At the same time, the whole culm becomes grounded.

As in the embodiment of the present invention, the support rods (29) that oppose the lower side of the conveyor belt (28) are provided at the rear side (a) and the front side (b). If the stems are deflected while being placed side by side to widely support the root side, which is heavier than the tip side, the straw (b) may be disturbed due to a stable posture change. Absent.

In addition, the conveyor belt (28) and the support rod (29) are hung downward with the base side thereof as a fulcrum in order to improve the handleability when traveling on the road or stored. Although it is configured to switch to the state, since the means is a conventionally known means, the description thereof will be omitted here.

[0014]

[Effect of the device]

 As is apparent from the above description, the present invention mounts the grain culm pinching and lateral feeding device (2) of the threshing machine (A) on the traveling chassis (1) so as to be orthogonal to the traveling direction of the machine body, and removes the machine body. A conveyor belt (28) and a support rod (29) are vertically arranged on the straw side to take the straw (a) toward the conveying direction of the grain-clamping lateral transfer device (2), and the stocker side is clamped. In a self-propelled threshing machine equipped with a straw discharging device (3) for slowing and discharging to the outside of the machine, discharge of straw (a) to the tip side outside the No. 4 gutter (4) on the straw side A resistance element (5) for preventing the above is provided to advance the stocker side, and the supporting rod (29) is bent diagonally downward on the upper side of the conveying action side end portion (0) of the conveying belt (28). The length (M) from the bent portion (P) of the supporting rod (29) to the terminal end (0) of the conveyor belt (28) on the conveyor side and the end thereof. The length (L) from the part (0) to the extended end (Q) of the support rod (29) is set to be the same or the length (L) is set to be larger than the length (M) and the discharge is performed. Since the straw (a) was dropped onto the ground in such a posture in the discharge direction (b), the threshed straw (a) was passed from the straw side to the straw discharge device (3). When it is discharged to the outside of the airframe by the resistor, the tip end side is blocked by the resistor (5) and the straw (a) was discharged in a state orthogonal to the discharge direction (b). When it is discharged so that the direction is gradually changed, and the stocker side reaches the bent portion (P) of the supporting rod (29), it is released from the conveying action of the conveying belt (28) and the supporting rod is directed obliquely downward ( 29) While being received by 29), it quickly slides on it and the stock descends to the outer side position of the fuselage, and is almost in the direction of movement of the fuselage. It is forcibly turned to such a posture in the intersecting direction, that is, the discharging direction (b), and it is arranged in order on the ground in order, and like the conventional one, the falling straws overlap with each other in a displaced state. Since it does not happen, recovery work after that will not be troublesome and it will be possible to sufficiently perform sun drying.
