Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a constituent member of a swing sorting body that is mounted below a handling room to sort threshing products from the handling room. .

(B) Conventional technology Conventionally, in a swing selection body mounted below a handling room, as a technical configuration for changing and adjusting the inclination of fins which are its constituent members, for example, Japanese Utility Model Publication No. 56-93150 It is disclosed in Japanese Laid-Open Patent Publication No. 60-174537.

However, of these publications, the former (Actual exploitation 56-93150
In the Japanese patent publication), the sensor for detecting the presence or absence of grain culm supplied to the threshing unit is used to change the inclination of the fin, which is a constituent member of the rocking sorting body. Is detected and the time when the grain culms are threshed and fall on the rocking sorter, and the rocking sorter cannot perform its sorting effect as desired. .

The latter (Japanese Utility Model Laid-Open No. 60-174537) detects the amount of the first grain below the oscillating sorter and detects and adjusts the inclination of the fins, so that the above-mentioned deviation occurs. Although it can be solved, the sensor that detects it is installed on the first-grade grain plate, so there is variation in the grains that fall on this first-grade grain plate, and the first-grain amount cannot be accurately grasped. Of.

(C) Problem to be Solved by the Invention As described above, although there is a conventional one that changes and adjusts the inclination of the fins of the rocking sorting body, in the former one, the presence or absence of grain culms to be supplied to the threshing section. Since it is changed by the sensor that senses, there is a large difference between the time when the sensor senses and the time when the threshing processed material falls on the rocking sorting body, and the rocking sorting body desires its function. However, according to the latter, the deviation in the former can be eliminated, but it is the first because it detects the uneven grain falling on the first-grade grain plate. There is a drawback that the grain amount cannot be accurately grasped.

Therefore, the present invention eliminates the problem of the former one, and changes the inclination of the fins of the rocking sorting body in accordance with an increase / decrease in the amount of threshing material from the handling chamber, as much as possible. , The latter one has the drawback that it is difficult to detect the increase and decrease fluctuations of the No. 1 grain quantity immediately after selection, and it is possible to sort the No. 1 kernel quantity by accurately grasping the No. 1 grain quantity. It was created for the purpose of effectively treating the processing action.

(D) Means for Solving the Problems The present invention, as a means for accomplishing the above object, changes and adjusts the inclination of the fins of the chaff sheave that constitutes the swing sorting body mounted below the handling chamber. In the end of the No. 1 grain trough that collects and sends out the No. 1 grain in a horizontal direction below the rocking sorter, a sensor for detecting an increase / decrease in the No. 1 grain quantity is provided. The inclination of the fin can be changed and adjusted by the detection of the sensor.

(E) Action According to this configuration, the threshed material from the handling room falls on the rocking sorting body and is received by the chaff sieve while being sifted by the fins of the chaff sieve, while the threshing material does not show cuttings such as spikes or grains with branch stems. The processed product is sent along with the straw waste toward the end, and the first grain, which has leaked from between the fins and is wind-selected, is taken out of the machine.

At this time, the 1st grain immediately after selection is collected and sent to the 1st grain gutter, but the sensor provided at the end of the 1st grain gutter is the 1st grain collected and sent in the gutter. Detecting the increase / decrease change of the whole grain, when the amount is increased, the inclination of the fins is made steep to facilitate leakage from between the fins, and when the amount is reduced, the inclination of the fins is made gentle to prevent leakage from between the fins. Thus, it is possible to prevent the leakage of unprocessed materials such as cuttings and grains with branch shoots, and to improve the selection, corresponding to the amount of the threshed material that falls on the rocking sorting body.

(F) Examples Hereinafter, the present invention will be specifically described with reference to the examples.
The threshing sorter shown in this example is for use with a combine, and the left side in FIG. 1 and FIG. 3 is the forward side with respect to the traveling direction, and the harvested grain culms are inherited for threshing and sorting. It is a thing.

Next, the chaff sheave (5) is replaced by a large number of fins (5
The a) is constructed by arranging the fins (5a) side by side in a slanting manner with a space in front and back, and the inclination of the fins (5a) can be changed.

That is, the left and right side walls (30) of the swing selecting body (a)
On each outside of (30), a pair of left and right links (33) (33) and (3) which rotate about axes (31) (31) and (32) (32) as fulcrums.
4) (34) are installed respectively, and each link (33) (3
3) and (34) (34) are attached to the lower ends of the adjusting rods (35) (35) fitted to the side walls (30) (30), respectively. ) (35) is provided with inclined holes (36) corresponding to the fins (5a) at equal intervals to the fins (5a), and the upper ends of the fins (5a) are inclined holes (36).
And slide it backwards to allow it to support the side walls (30) (30).
The lower end is inserted into this inclined hole (36) and arranged in an inclined manner, and the pair of links (33) (33) and (34) (34) are oscillated through the adjusting rods (35) (35). Each fin (5a) has its inclination changed.

Further, (37) is a sensor in which the end of the 1st grain gutter (24) hangs integrally with the crocodile horizontal axis (38), and the lower end thereof is a screw installed in the 1st grain gutter (24). Conveyor (3
Formed in an arc along the outer periphery of 9), and the 1st grain gutter (24)
The inner end is configured to change its posture with the horizontal axis (38) as a fulcrum by the No. 1 grain pressure delivered from the end.

Further, (40) is an arm projecting from one end of the horizontal axis (38), and the upper end of this arm (40) has the pair of links (3
3) The lower end of one of the links (33) (33) is connected to the wire (41). Reference numeral (42) is a return spring that connects the upper end of the link (33) and an appropriate position of the side wall (30).

Therefore, the threshed material from the handling chamber (1) is sorted by the swinging of the swinging sorting body (a) in the front-rear direction and the sorting wind of the compressed air fan (9), and the spacing between the fins (5a) and the Glen sieve (7). No. 1 grain that has leaked from) fell into the No. 1 grain trough (24), and fine dust blown up by the sorting wind was sucked and discharged by the suction dust removal fans (16) (17) on both sides, resulting in a large straw. Waste and unprocessed material such as cuttings and grains with branching stems are received from the end of the Strawac (6) into the processing cylinder chamber (3) from their entire width and rotate in the direction of (b) (10). It is processed by migrating from bottom to top.

The dust generated by this processing action and trying to move around in the processing chamber (3) is sucked and discharged by the fan (16) (17).
The leaked substance from the concave (11) is received by the sorting rack (8), and the swinging of the leaked substance separates the straw and branch shoots and discharges it from the rear end.

In addition, the 1st grain dropped into the 1st grain gutter (24) is sent to the end of the grain and taken out from the 1st grain grain lower (29), and the 2nd grain gutter (25 Items in () are lifted to the reprocessing chamber (27) by the No. 2 thrower (26) and processed, and those which are not processed yet are returned to the handling chamber (1) from the reduction port (28).

At this time, when the amount of the No. 1 grain sent by the screw conveyor (39) toward the end of the No. 1 grain gutter (24) is increased, the sensor (37) causes the horizontal axis ( The posture can be changed as shown by the arrow (C) with 38) as the fulcrum. Then, the arm (40) exerts a pulling action on the wire (41), which causes the pair of links (33, 33) to swing about the shafts (31, 31) against the return spring (42). Each of the adjusting rods (35) (35) is moved so that the fins (5a) are steeply inclined so that the fins (5a) are easily leaked from each other, and the amount sent out in the first grain trough (24) is reduced. When it decreases, the delivery pressure to the sensor (37) is weakened, and the spring force of the return spring (42) makes the inclination of the fin (5a) gentle, so that the fin (5a) hardly leaks from between the fins (5a).

(G) Effect of the Invention As described above, the present invention changes and adjusts the inclination of the fins of the chaff sheave that constitutes the swing selecting body mounted below the handling chamber. The end of No. 1 grain gutter which is installed horizontally and collects and sends out No. 1 grain 1
Since a sensor for detecting an increase / decrease in the number of grain is provided, and the inclination of the fin can be changed and adjusted by the detection of the sensor, the sensor immediately after passing through the swing sorting body can be used.
Since the fin inclination is changed and adjusted according to the increase and decrease in the number of grain, the large deviation between the time when the threshing material from the handling room falls on the rocking sorting body and the time when the sensor detects it is eliminated and the fin inclination is reduced. While the sensor that can detect the amount of the first grain immediately after threshing can be made to correspond to the amount of the threshing material that falls on the rocking sorting body, the end of the first grain gutter is provided in the crocodile. Since the entire No. 1 grain that is collectively sent out in the gutter is sensed, the increase / decrease fluctuation of the No. 1 grain amount can be grasped accurately, and the sorting process can be effectively performed and the sorting can be made good. .
