Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a soybean sorting apparatus which has undergone a shattering treatment, and more specifically, a soybean sorting method in which soybeans stored in the mouth are prevented from being mixed with stalks. Regarding the device.

[Prior Art] A soybean combine is constructed as shown in FIGS. 3 and 4. In other words, the soybean combine 1 is a pretreatment unit 2 that conveys soybean stalks to the upper side of cutting, a transfer unit 3 that continuously transfers the stalks of the pretreatment unit 2, and a transfer unit that is arranged behind this transfer unit 3 It comprises a shredding chamber 4 for shredding the soybean culm from the part 3, and a sorting part 5 arranged below the shredding chamber 3 for sorting the shredded products.

The pretreatment unit 2 is provided with a pair of left and right lower conveying devices 9 each including a stock carrier 6 and a carding carrier 7, and a hair clipper that laterally overlaps the front ends of the carriers 6 and 7. A mold cutting blade 11 is provided. Further, there is provided an upper transfer device 14 including a stock-source carrier 12 and a stock-target carrier 13 for transferring and transporting the stem culms carried by the carriers 6, 7.

The relay unit 3 is a lower carrier in which lugs are erected on a belt.
15 and a stock source carrier and a stock destination carrier which are provided facing the lower carrier 15 and have an upper carrier 16 in which a lug is planted on a belt. 15
Has an upper half protruding from a groove opening in the supply table 17.

The shedding chamber 4 is formed in a cross shape in a side view.
A plurality of processing cylinders 19 arranged in parallel across the width direction of the processing cylinder 19 are rotatably provided, and a punched iron plate 20 having a large number of leakage holes is provided below the processing cylinder 19 in a curved shape. The leaked substance that has leaked from the punched iron plate 20 is transferred rearward by a non-hole corrugated oscillating plate 21 that is disposed directly below the punched iron plate 20 in a substantially horizontal direction and agitates.

In the sorting section 5 arranged below the non-perforated corrugated rocking plate 21, there are formed a main sorting wind passage 23 and a sub sorting wind passage 24 through which the sorting wind blown backward from the main Karasu 22 passes. A first conveyor belt 25 inclined obliquely upward is rotatably arranged in the main sorting air duct 23, and a second conveyor belt inclined obliquely upward is provided in the sub sorting air duct 24. 26 are rotatably provided, and the lower portions of the two conveyor belts 25, 26 are connected to the first gutters 27 and 29 having the largest spirals respectively, and the conveyor belts 25 and 26 are driven by It is wound between a roller fixed to the shaft and a roller fixed to the driven shaft.

Therefore, the leaked substance discharged from the end of the non-perforated corrugated rocking plate 21 into the sorting air passage 23 first drops onto the first conveyor belt 25. Since the first conveyor belt 25 moves diagonally from the lower side to the upper side, soybeans having a nearly spherical shape are transferred to the conveyor belt.
25 Rolled upward and stored in the first gutter 27, but one of the stem culms and a small amount of soybeans that had been shredded into a cut state were moved upward as the conveyor belt 25 moved. And is dropped and supplied onto the second conveyor belt 26 from the end thereof.

On the second conveyor belt 26, the soybeans, which are close to the spherical shape like the conveyor belt 25, roll downward on the conveyor belt 26 and are stored in the first trough 29, but one of them is cut. The stem culms and a small amount of soybeans in the state are conveyed upward with the movement of the conveyor belt 26 and discharged to the outside of the machine while sliding on the spokes 31 from the ends thereof, but leaked from between the lines of the spokes 31. The soybeans are stored in the suspended storage bag 32.

Further, the processed material that has not leaked through the punched iron plate 20 of the shredding chamber 4 is supplied above the conveyor belt 25 while sliding through the dust outlet 33 and on the spokes 34, and along with the movement of the conveyor belt 25. The soybeans, which are mainly supplied onto the second conveyor belt 26 but leaked through the spokes 34, are stored in the first trough 27 while rolling downward on the first conveyor belt 25.

[Problems to be solved by the invention]

By the way, in the sorting by the sorting unit 5, the soybean culm that is cut and has a nearly circular cross-section among the processed products that have dropped onto the respective transport belts 25 and 26 when the stalk direction is the lateral direction. Since it rolls downwards on 26 and 26 in the same way as soybeans, there was a problem that it was most likely to mix with each of the gutters 27 and 29.

As a means for preventing the soybean stem culm from mixing into the mouth at the most, comb tooth-shaped sorting bodies (spokes) 35 and 36 inclined forward and downward are respectively provided on the conveyor belts 25 and 26, respectively. It is known that the sorting bodies 35 and 36 prevent the movement of soybean stem culms which try to roll downward.

However, if the comb tooth-shaped sorting bodies 35 and 36 are simply provided on the respective conveyor belts 25 and 26, the soybean culms that are prevented from moving downward are deposited on the comb tooth-shaped sorting bodies 35 and 36. However, since it hinders the soybeans from rolling downwards and the passage of sorting air, there is a problem that sorting cannot be done unless the soybeans are removed.

In view of the above-mentioned conventional circumstances, the present invention was devised to solve the problem, and a conveyor belt that moves diagonally from the lower side to the upper side passes between the spokes of the comb-teeth-shaped sorting body. The present invention is carried out for the purpose of providing a soybean sorting apparatus capable of preventing the accumulation of soybean stalks on the comb tooth-shaped sorting body and preventing the mixing of the soybean stalks at the first mouth by providing the transport protrusions. It is a thing.

[Means for solving problems]

The present invention that achieves the above object is provided with a conveyor belt that obliquely moves upward from the position connected to the most gutter in the sorting air passage leading to the shredding chamber, and the conveyor belt is moved toward the conveyor surface toward the front. A comb tooth-shaped sorting body consisting of a plurality of spokes that are provided side by side with a gap that allows soybeans to incline in a descending manner is provided opposite to the conveyor belt, and a plurality of conveyor protrusions are provided in the width direction of the conveyor belt. The comb-shaped sorting body is made to pass between the spokes.

[Action]

Therefore, in the sorting air passage 23 leading to the shredding chamber 4, the first gutter
A conveyor belt 25 that obliquely moves upward from a position where it is connected to the conveyor belt 27 is provided, and a comb-teeth-shaped sorting body 35 including a plurality of spokes 40 that are inclined downward toward the conveyor surface of the conveyor belt 25 is provided. Also in the case of the above, the conveyor belt 25 is provided with a plurality of conveyor protrusions 37 in the width direction, and the conveyor protrusions 37 are passed between the spokes 40 of the comb-tooth-shaped sorting body 35 to form a comb-tooth shape. The soybean culm, which is prevented from moving downward by the sorting body 35, can be removed by the transport protrusion 37 that moves upward together with the transport belt while passing between the spokes 40.

This prevents the soybean stem culms from accumulating on the comb-toothed sorter 35, and allows the soybeans to roll downward well,
It is possible to reliably prevent soybean stem culms from being mixed in the first gutter 27.

〔Example〕

Hereinafter, the drawings showing the present invention as an embodiment will be described.

In the following, a configuration characterized by the present invention shown in FIGS. 1 and 2 will be described while avoiding the duplication of the conventional technique described above.

That is, in the sorting air passages 23 and 24 leading to the shredding chamber 4, the conveyor belts 25 and 26 that obliquely move from the lower side to the upper side.
Are provided respectively, and the comb tooth-shaped sorting bodies 35 and 36, which are inclined downward in the front direction, are respectively installed at substantially central portions in the length direction of the transport surfaces of the transport belts 25 and 26. Each of the comb tooth-shaped sorting bodies 35 and 36 has a mounting seat 41a fixed to both side walls of the sorting portion 5 and has a mounting bracket 41 extending in the width direction.
And a plurality of spokes 40 fixed to the mounting bracket 41 in the lateral direction so as to have a substantially U-shape in a plan view, and soybeans pass through the lateral distance H of the spokes 40. The conveyor belts 25 and 26 facing each other are provided with a large number of conveyor protrusions 37 and 39 over their lateral widths, and the lateral spacing H of the spokes 40 of the comb-shaped sorting bodies 35 and 36 is H. Are provided at a lateral interval S that passes through substantially the center.

Each of the conveyor belts 25 and 26 is formed of a rubber plate (or may be a synthetic resin such as nylon) and has a conveyor protrusion.
37 and 39 are integrally formed with the conveyor belts 25 and 26, or the respective conveyor protrusions 37 and 39 are fixedly adhered to the conveyor belts 25 and 26, and the spokes 40 are composed of piano wire or the like. If it is made of synthetic resin, its tip can be provided close to or in contact with each of the conveyor belts 25 and 26, and there is an advantage that the contact resistance in the moving direction of each conveyor belt can be reduced and elastically deformed. .

The height T of each of the transport protrusions 37 and 39 is set so that the lap margin R with the tip of the spoke 40 is 10 mm to 25 mm, and pulls the lateral soybean stem culms locked on the spoke 40. The height is such that it hangs and moves upward.

Each of the transport protrusions 37 and 39 shown in the embodiment corresponds to each of the transport belts 25.
Although they are provided in a direction orthogonal to the conveying surfaces of and 26, when they are attached in the vertical direction, the stalks accumulated on the spokes 40 of the comb tooth-shaped sorting bodies 35 and 36 can be removed more effectively. Further, although the respective transport protrusions 37 and 39 shown in the embodiment are provided at one location on each of the transport belts 25 and 26, they may be provided at two locations or at three locations.

Further, in the embodiment, an example in which the first and second conveyor belts are provided in the sorting section 5 is shown, but one conveyor belt is arranged in the main sorting air passage 23 or the sub sorting air passage 24. Also available for construction. Furthermore, an example in which it is mounted on a soybean combine is shown, but it can also be applied to a soybean thresher having a shedding chamber and a sorting section.

[Effect of device]

As described above, according to the present invention, the sorting air passage leading to the shredding chamber is provided with the inclined conveyor belt that moves obliquely upward from the position connected to the most gutter, and the conveyor surface of the conveyor belt. Even if a comb-tooth sorter consisting of a plurality of spokes inclined downward toward the front is provided, a plurality of transport protrusions provided in the width direction of the transport belt pass between the spokes of the comb-tooth sorter. By doing so, the soybean culm, which is prevented from moving downward by the comb-tooth sorter, is removed by the transport protrusions that move diagonally together with the transport belt upward while passing between the spokes. You can

Therefore, the soybean culm can be prevented from accumulating on the spokes of the comb-teeth sorter, and the soybeans can be tumbled well, so that the soybean culm is mixed in the most gutter. It can be surely prevented.
