DETAILED DESCRIPTION OF THE INVENTION
【Example】
Hereinafter, a diffusion conveyor device for evenly distributing deposits on a rocking sorter according to the present invention will be described with reference to an embodiment diagram mounted on a combine. FIG. 5 is an overall right side view of a threshing machine mounted on a combine. The threshing part B is mounted on a machine base 13 equipped with a pair of crawler traveling devices 12, and the cerealing plate 15 is planted with the weeding board 15 while the cutting height A is adjusted by mounting the cutting part A that can be moved up and down. By a lifting cylinder that floats the ridge, cuts and connects with the cutting blade 16, it is passed to the start end side of the feed chain 17 stretched on the threshing portion B, and is handled by a handling cylinder 20 mounted in the handling chamber 18. A grain removal process is performed, and the handling material falls from the receiving net 21 provided on the outside and is temporarily received on the swing sorting body 1, and is cerealed by the chaff sheave 22 or the grain sieve 32 that swings back and forth. Adjacent to the bottom while screening the grains That induces the sorting unit 5, and AtsumariKoku in 1st conveyor 37 the good grain after removal of the dust in the arrow b direction sorting wind in the form of a combine which is adapted temporarily stored in grain tank 23.
[0008]
The front view of the threshing section in FIG. 2 and the entire route of the combined harvester in FIG. 5 will be described as follows. On the other hand, the untreated material that has been shattered by the handling cylinder 20 and leaked from the receiving net 21 is dropped to the starting end side of the swing sorting device C arranged side by side while the untreated material moved rearward in the handling chamber 18. The processing cylinder 8 mounted in the processing chamber 25 is cerealed and reprocessed, and the end is connected to the suction fan 43 so that dust is discharged from the dust outlet 45 to the outside of the machine. Further, the swing sorter 1 for sorting and sorting the wholesaled goods is supported by the arm 26 from the side plate 6 of the sorting unit 5, and the swing sorter C for screening the grain by applying a swinging motion in the front and rear direction. It is a configuration.
[0009]
A non-porous feed pan 2 is stretched on the start end side of such a swing sorting device C, and the handling material is temporarily moved rearward by the corrugated surface 28 to continuously connect the chaff sheave 22 and the Glen sheave. Screening is performed at 32, guided to the sorting unit 5 arranged in parallel below, and evenly fed to the wind sorting path 42 where the fan 27 wakes up, and dust mixed in by the sorting wind blown in the direction of arrow a is separated. This is a sorting path in which wind sorting is performed and temporary grains are stored in the glen tank 23 by a cerealing machine continuously arranged while collecting good grains on the first conveyor 37. On the other hand, the 2nd thing in which the small amount of grain and unprocessed thing which fell to the 2nd conveyor 40 is mixed is reduced with the whipping cylinder 41 to the upper side of the diffusion conveyor 3 arranged on the feed pan 2, and is discharged from the discharge port 55. This is a reduction path where the discharged second product and the handling material deposited on the processing cylinder 8 side of the rocking sorter 1 join together, and the deposition line X that is offset to the right side grows to a more remarkable mountain height. In order to eliminate this phenomenon, the oscillating sorting apparatus C is equipped with a diffusion conveyor 3 and forcibly diffused.
[0010]
FIG. 1 is a rear view in which a diffusion conveyor is provided on an oscillating sorter, and its operation and structure will be described with reference to a side view in which the main part of FIG. The starting end side of the swing sorter 1 is faced below the receiving net 21, and the handling material on the feed pan 2 and the second thing conveyed by the cereal cylinder 41 are merged as described above, and once received, corrugated The surface 28 is moved back and forth by swinging back and forth, but a large amount of grain leaks to the processing cylinder 8 side in the direction of the arrow B in which the handling cylinder 20 rotates, and a deposition line X is formed in which the right side is a mountain height. In the guide plate of the prior art that disperses such a phenomenon, the moving speed becomes slower than the processing amount at the time of high efficiency, and the diffusion corresponding to the deposition amount cannot be performed, and the deposited layer moves thickly in the continuous chaff sheave 22. However, even if the lower layer drops, the surface layer remains and continues to the rear of the swing sorting device C, and the loss particles increase, so that a functional failure such as a reduction in work speed occurs.
[0011]
The installation of the diffusion conveyor for eliminating the height of the accumulation line X is made close to the corrugated surface 28 of the feed pan 2 to forcibly disperse the height of the accumulation line X from the right side of the swinging sorter 1 in the direction of the arrow D. It is a diffusion conveyor 3 to be controlled, and is a grain guide 11 that is opposed to the discharge side 10 of the conveyance length L, and controls grain suppression and lateral feed amount. The attachment is made by welding the contact plate 31 to the back surface of the feed pan 2 and screwing the “<” shape of the Glen guide 11 so as to be inclined upward, and interlocking with the swinging motion in the arrow direction. Since the grains gather on the discharge side 10 and are released backward while repeating compression and expansion, pulsation occurs in the discharged grains, and the fixed amount overflows from the grain guide 11 in the direction of the arrow H, and the discharge amount and the lateral feed amount. This is a diffusion device that maintains the balance. The end of the conveying length L that causes this lateral feed is kept inside the handling cylinder center 7, and the over-transferred grains are released by providing a non-acting air space on the small amount side of the deposition line X, The swing sorting device C is capable of forcibly diffusing left and right on the swing sorting body 1.
[0012]
The driving structure will be described with a front view of the threshing section in FIG. 2 and a rear view of the diffusion conveyor shown in FIG. 1. The V belt 46 is wound around a pulley that drives each part of the threshing section B, and the winding angle is set. The driving pulley 52 has a small diameter integrated with the rear pulley 47 to be adjusted, and is configured to transmit a proper rotation to the conveyor shaft 51 supported by the bearing 50 with a slidable split pulley structure. The input pulley 48 fixed to the shaft end is input to the rotational speed of the diffusion conveyor 3 to prevent the winding of the coffin mixed with the adjustment of the lateral feed speed in the direction of the arrow D by inputting the decelerated rotation from the drive pulley 52. Is.
[0013]
A structure in which a speed change mechanism is added to such a belt input structure and the structure that changes according to the processing amount is shown in a related diagram for shifting the diffusion conveyor of FIG. A sensor 56 having a potentiometer 62 connected to the shaft end that moves up and down is provided between the conveying rods, and the amount of operation that descends in the direction of the arrow is detected and transmitted to the controller 63 to be specified in the electric motor 65. As the tension pulley 66 is rotated in the direction of the arrow by outputting the rotation and the tension force of the drive belt 67 is changed, the drive pulley 52 in which the split pulley is pressed by the spring 68 is expanded. A belt transmission structure is provided for increasing or decreasing the rotation of the conveyor shaft 51. In addition, the illustrated position shows the low-speed rotation state of the diffusion conveyor 3 that does not sandwich the waste.
[0014]
FIG. 4 is a perspective view of the diffusion conveyor, which is formed by being divided by a partition plate 36 attached to the rear of the mesh 21 and receiving the dust feed port 33 that opens to the terminal side of the handling chamber 18. The unprocessed material and dust that have not leaked from the discharge path are sent in the direction of the arrow, and are transferred to the start end side of the parallel processing cylinder 8. It is horizontally arranged on the feed pan 2 on the upper side, and is arranged so that the discharge side 10 faces the lower side of the delivery plate 35 through the Glen guide 11 opposed to the conveyance length L. The part discharged to the rear is the end side of the feed pan 2 and has a conveyor arrangement in which the fallen matter is few, the deposited layer is thin, and the diffusion of the released grains is further promoted.
[0015]
