Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention connects a mechanism for adjusting the inclination angle of the fins of the swing sorting body for sorting the items to be handled from the handling room with a sensor for detecting the amount of grain, which is linked to the operation of the sensor. The present invention relates to a fin tilt angle control device for a threshing rocking sorting body that controls the tilt angle of fins.

[0002]

[Prior Art]

 Such a fin tilt that controls the tilt angle of the fin by connecting the wire with the fin tilt angle adjusting mechanism of the rocking sorting body and the sensor that detects the amount of grain, and controlling the tilt angle of the fin in conjunction with the operation of the sensor. In the conventional means of the angle control device, since the inclination angle of the wire is changed by pulling the wire, an error occurs in the relation with the amount of grain and culm as the wire is stretched during use, which affects the selection. However, there are some problems such as loss of grain and the like.

[0003]

[Problems to be solved by the device]

 Therefore, the present invention eliminates the change in the relative relationship between the amount of culm and the angle of inclination of the fins, solves the above-mentioned conventional problems, improves the sorting action, and eliminates the loss of grain. The purpose of the present invention is to provide an oscillating sorting body.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention uses a wire to connect a fin tilt angle adjusting mechanism of a rocking sorting body that sorts goods to be handled from a handling room and a sensor that detects a grain amount. However, in the case of controlling the inclination angle of the fin in conjunction with the operation of the sensor, the inclination angle of the fin is changed by the pushing action of the wire by the operation of the detection sensor to automatically adjust the gap between the fins. It was configured to do so.

[0005]

With this configuration, when the amount of grain culm is detected by the sensor, and the tilt angle of the fin is changed and adjusted by the operation of the sensor based on the detection, the wire is adjusted by the pushing action of the wire. The initial selection state is maintained because the relative relationship with the amount of grain and culm does not change because the growth does not occur.

【Example】

 The fin tilt angle control device according to the present invention will be described below with reference to an example diagram. Since this device is a main part of what constitutes a combine, an outline of the entire combine will be described with reference to FIG. And (6) is a running chassis supported by the left and right crawlers (7), and (A) is a handling room (1) having a handling chain (9) with a feed chain (8) stretched on the left side. And a shaking sorting body (2) for sorting threshing from this handling room (1) and a straw conveying device (10) that carries out the threshed waste after feeding from the feed chain (8). A thresher equipped with it, which is mounted on the left side of the traveling chassis (6), (11) is a control unit, (12) is a grain tank for storing grains from the threshing machine (A), and (E) is an engine. There are these controls (11), grain tank (12), engine (E) Are sequentially arranged on the right side of the traveling chassis (6) from the front side.

(B) is provided on the front side of the thresher (A) equipped with a weeding board (13), a raising device (14), a cutting blade (15), a harvested culm transfer mechanism (16), etc. The harvesting section (17) is a discharge auger that lifts up and removes the grains stored in the grain tank (12), and a straw cutter is provided at the end side of the straw transfer device (10). (18) is attached.

As a result, the grain culms mowed by the mowing unit (B) are supplied to the threshing machine (A) and are threshed by the handling drum (9) while being sandwiched and transferred by the feed chain (8), The processed grain is now stored in the grain tank (12), and the straw after threshing is transferred from the feed chain (8) to the straw transport device (10) to the rear. The grains are carried out to the straw cutter (18) and cut into a predetermined length, and the grains stored in the grain tank (12) are properly taken out of the machine from the discharge auger (17). It is like this.

Next, the main part of the present invention will be described. The chaff sheave (19) constituting the rocking sorting body (2) for receiving the grain removed from the handling chamber (1) and sorting is a large number of fins. The fins (3) are tilted with the upper end as a fulcrum so that the tilt angle can be changed and the gap between the fins can be adjusted. It has become.

(4) is an inclination angle adjusting mechanism for changing the inclination angle of each fin (3), which can be swung in the swinging direction of the swing selecting body (2) with the upper and lower intermediate portions as fulcrums (20). Since the lower end of each fin (3) is engaged with the interlocking rod (22) connected to the lower side of the operating rod (21) by a pivot, the tilt angle is simultaneously changed by the swinging of the operating rod (21). is there.

In addition, the straw transfer device (10) that carries the straw after threshing from the terminal end of the feed chain (8) and carries it out to the straw cutter (18) is vertically moved to the chain (23). ) And a sandwiching rail (24) are provided in opposition to each other, and the front side and the rear side of the sandwiching rail (24) are compressed by the compression springs (25) toward the transport chain (23) and are carried out. The pinch rail (24) functions as a sensor (S) that moves up and down due to fluctuations in the amount of grain culm to detect the amount of grain culm.

Then, the lower end of the supporting rod (26) near the rear side of the pinch rail (24) and the upper end of the operating rod (21) are connected by a wire (5) to form an operating rod ( The lower end of 21) is steeply pulled by a return spring (27) having a weaker spring force than the compression spring (25).

Accordingly, the sensor- (S), which is the clamping rail (24), detects the increase / decrease in the amount of grain culms carried by the straw-transporting device (10), and detects the sensor- (S). It is changed and adjusted through the wire (5) and the tilt angle adjusting mechanism (4) by the up and down movement, but for example, it is returned in the non-operating state when it is not carried out by the straw transfer device (10). The spring force of the compression spring (25) overcomes the spring force of the spring (27), and the pinching rail (24) moves upward. That is, when the sensor (S) detects that there is no grain culm, the wire (5) is pulled and the operating rod (21) swings about the fulcrum (20) as an axis to move through the interlocking rod (22) to reach each fin. The inclination angle of (3) becomes gentle and the gap of the fin (3) becomes zero. On the other hand, in the operating state in which the wire is transferred by the straw transfer device (10), the pinch rail (24), that is, the sensor (S) moves downward, which causes the wire (5) to bend. In addition, the return spring (27) acts to swing the actuating rod (21) in the opposite direction to the above to steeply incline the fin (3) and open the gap between the fins (3). The gap is adjusted by the pushing action of).

[Effect of the device]

 INDUSTRIAL APPLICABILITY As described above, the present invention provides a tilt angle adjusting mechanism (4) for the fins (3) of the rocking sorting body (2) for sorting unprocessed goods from the handling room (1) and a sensor for detecting the amount of grain. -(S) is connected by a wire (5) and the inclination angle of the fin (3) is controlled in conjunction with the operation of the sensor (S), which depends on the operation of the detection sensor (S). Since the inclination angle of the fins (3) is changed by the pushing action of the wire (5) to automatically adjust the gap between the fins (3), the amount of grain culm is detected by the sensor ( When the tilt angle of the fin (3) is changed and adjusted by the operation of the sensor (S) detected by S), the wire (5) is adjusted by the pushing action of the wire (5). ) Does not grow and the relative relationship with the amount of culms does not change. Since the initial selection state is maintained, sorting action can be eliminated improved grain loss.
