[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a fry conveyor for transferring paddy to a Glen tank.

[0002]

2. Description of the Related Art Conventionally, a first conveyor and a second conveyor are arranged before and after a swing main body of a swing sorting apparatus, and a reduction conveyor is arranged at the other end of the second conveyor. The discharge port at the other end of the conveyor is arranged so as to face the front of the crimping net of the oscillating sorting device so that the second product is reduced and sorting is performed again. The first conveyor extends to the side of the Glen tank, is located rearward in the front-rear direction when viewed from the side, projects the fried conveyor forward and upward, and inputs paddy from the front side of the Glen tank. Had become. In addition, a vertical conveyor rotatably supporting the discharge auger is provided at the rear of the fuselage, and the paddy stored in the Glen tank is discharged using the discharge auger.

However, the conventional fry conveyor, which is arranged to be inclined forward and is charged from the front of the Glen tank, has a configuration extending from the bottom rear to the upper front of the Glen tank. The length of the conveyor was increased, and the side shape of the Glen tank was limited. Further, a vertical conveyor arranged at the rear of the machine body is stably supported by a supporting column standing upright from the main body. For this reason, there has been a demand for a configuration of a fried conveyor capable of stably supporting the left-hand side shape of the tank as little as possible. .

[0004]

SUMMARY OF THE INVENTION In order to solve such a problem, the present invention is directed to a configuration in which the first conveyor from the first conveyor of a swing sorting apparatus is transported to a Glen tank using a frying conveyor. The above-mentioned conveyer was inclined backward and protruded upward, so that paddy was charged forward from the upper rear part of the Glen tank.

07, the fixing bolt 111 is inserted into the fixing bolt 1
The fixed ring 102 is screwed at the lower part of the reference numeral 11. The fixed ring 102 has a rib 10 on its upper surface as shown in FIG.
Holes 102a, 102a having the same axis as 7 and 107 are opened, and a semicircular portion 102b having a semicircular shape in side view is formed on the lower surface of the fixed ring 102. The driven ring 103 has a semicircular portion 103a having a substantially semicircular shape in a side view, and a fitting portion 103b protrudes forward and downward at one end of the semicircular portion 103a, and a shaft hole is formed in the fitting portion 103b. 103c is open. As shown in FIGS. 10 and 11, a swing ring 104 is provided inside the driven ring 103. The swing ring 104 has a front ring 104a and a rear ring 104b opened in front and back, and is formed vertically into two parts. Further, a reinforcing plate is disposed on the side of the inclined portion 106 of the swing main body 51, and the fixed plate 101 and the side of the fixed ring 102 are screwed together to receive vibration caused by the swing. The rear part of the swinging main body 51 is reinforced.

With this configuration, the driven ring 103
Semi-circular portion 103a and semi-circular portion 102b of driven ring 103
The crankshaft 53 is inserted by this circle, and the swing shaft 108 is fitted to the fitting portion 103 of the driven ring 103. And the rear ring 10 of the swing link.
4b, the crank portion 53a of the crank shaft 53 is pivotally supported, the front ring 104a is pivotally supported by the swing shaft 108, and the swing shaft 108
The roller 109 is fitted to the end of the body, and is fitted to a guide body 110 fixed to the main body (machine body) shown in FIG.
When the crankshaft 53 swings, the swinging shaft 108 swings through the swinging ring 104, and the roller 10 of the swinging shaft 108
9 reciprocates along the guide body 110, thereby reciprocating the driven ring 103 fitted with the swing shaft 108, thereby reciprocating the front part of the swing main body 51 in the direction along the guide body 110. Thus, the swinging body 51 swings.

The sieving line 70 for guiding paddy and the like, which is disposed in the vicinity of the back of the grain pan 58 of the swing body 51, will be described. As shown in FIGS. 2, 7, and 8, the screen guide portion 71 pivotally supports the pivot shaft 72 on the side plate at a position behind the Glen pan 58 of the swinging body 51, and the pivot shaft 72 between the side plates. Are fixed on the upper surface. Are formed in a rod shape extending in the front-rear direction, fixed on the outer peripheral surface of the pivot shaft 72 at regular intervals in the left-right direction, and the rear ends of the respective wire lines 70, 70,. The portion extends to a position near the front of the chaff portion 55.

Further, the screen guide 71 is configured to swing. That is, as shown in FIGS. 7 and 8, an arm 74 is fixed to one end of the pivot shaft 72 pivotally supported at a position behind the Glen pan 58 of the swing body 51, and the front end of the arm 74 is The arm 74 extends to a position near the separation wind introduction port 60, and the swinging shaft 7 extends laterally from the front side surface of the arm 74.
5 are projected. On the other hand, an arc-shaped long hole 79 is formed on the side surface of the swing main body 51 at a position near the sorting wind introduction port 60.
The swing shaft 75 penetrates through the elongated hole 79, and a guide roller 76 is fitted to the end of the swing shaft 75. The guide roller 76 is fitted between two parallel plate bodies 77 'and 77' fixed to a side plate of the main body (body) that covers the side of the swing main body 51. doing. The left and right ends of a pivot shaft 72 for pivotally supporting the front part of the swing main body 51 are fitted to a guide body 77 'fixed to a side plate on the main body side. Then, the guide roller 76 is guided by the guide members 77 ′ and 77 ′ to move back and forth, and the position of the pivot shaft 72 and the guide roller 76 is changed, so that the arm 74 is rotated.
The screen guide 71 is also rotated at the same time, and the screen guide 71 is oscillated by the swing of the swing body 51, and swings and conveys the rice straw and the like dropped on the chaff 55 while sifting. However, it is also possible to eliminate the arm 74 and fix the pivot shaft 72. In this case, the swing of the swing body 51 causes the sift wires 70 to swing simultaneously.

Also, a straw rack 78 is provided in parallel with the plurality of wire lines 70, 70,.
Can also be arranged. As shown in FIG. 8, the straw rack 78 is formed as a long plate in the front-rear direction.
2 and the upper surface of the plate-like body is formed in a sawtooth shape to form a straw rack 78, and the rice straw to be fed onto the chaff 55 is guided backward by the sawtooth-shaped straw rack 78. Also, the straw racks 78, 78...
Are alternately arranged between the sieving lines 70, 70 ...
The straw racks 78, 78,... Can be arranged every several of the plurality of screened wires 70, 70,. Therefore, the fine rice straw is dropped from the screen guide portion 71 and is transported rearward on the wind introduced from the introduction port 60. By transporting the fine rice straw to the rear, the rice straw is not mixed in the first thing, and the efficiency of the specific gravity sorting is enhanced by the chaff portion 55.

The karano 35, which performs the wind sorting of the swing sorting apparatus C, is disposed below the front part of the swing body 51 (below the position between the sorting wind inlet 60 and the start end of the grain sieve 57). A first conveyor 22 for transporting fine granules and a second conveyor 23 for transporting a second product are arranged in the rear of the Karino 35 in order. In addition, a pre-fan 41 that blows air to the sorting wind inlet 60 of the swinging body 51 is provided in front of the Karino 35.
