[0023] A large auger shaft 3 and a small auger shaft 4 are rotatably arranged in the body of the feed box 15, wherein one end of the large auger shaft 3 extends from the feed box 15 and extends to the first feed cylinder 1 to push the material in the feed box 15 into the discharge cylinder 14, and one end of the small auger shaft 4 extends from the feed box 15 and extends to the first feed cylinder 1 to push the material in the feed box 15 into the discharge cylinder 14, and the large auger shaft 3 is located above the small auger shaft 4 in the vertical direction.

[0024] The tail end of the large auger shaft 3 is rotatably supported on the feed box 15 through a first double-row bearing 19 , and the front end of the large auger shaft 3 is rotatably supported on the discharge barrel 14 through a set of second bearings 20 .

[0025] The tail end of the small auger shaft 4 is rotatably supported on the feed box 15 through a third double-row bearing 21, and the front end of the small auger shaft 4 is rotatably supported on the discharge barrel 15 through a set of fourth bearings 22. This support method of the large auger shaft 3 and the small auger shaft 4 can avoid jumping during operation and ensure stable and reliable operation.

[0026] A valve flap 10 is rotatably provided at the discharge port 2 of the discharge barrel 14 , and the valve flap 10 can realize opening and closing control of the discharge port 2 of the discharge barrel 14 , so as to realize reliable and smooth discharge operation.

[0027] Furthermore, in order to realize reliable opening and closing control of the discharge port 2 of the discharge barrel 14 , the outer surface of the discharge barrel 14 is hinged with a cylinder 18 , and the cylinder 18 can drive the valve flap 10 to rotate to control the opening and closing of the discharge barrel 14 .

[0028] The shaft of the valve flap 10 is rotatably supported on a bearing seat on the discharge barrel 14 , and a connecting plate is fixed to one shaft end of the valve flap 10 , and the connecting plate is hingedly connected to the piston rod end of the cylinder 18 .

[0029] A bagging dust removal port 13 and an air return port 17 are provided at the top of the discharge barrel 14 . The bagging dust removal port 13 is used for dust removal during material unloading, and the air return port 17 is used for air return to the discharge barrel 14 .

[0030] The first motor base 5 and the second motor base 6 are installed on the side of the feed box 15, and a group of reducers 12 are respectively installed on the first motor base 5 and the second motor base 6. The two groups of reducers 12 drive the large auger shaft 3 and the small auger shaft 4 to rotate through a group of couplings.

[0031] like Figure 5 As shown, a partition plate is provided in the inner cavity of the feed box 15 to separate the large auger shaft 3 and the small auger shaft 4 into two cavities, and a stirring shaft 7 is rotatably provided above the small auger shaft 4 in the cavity of the feed box 15, and a driven sprocket 9 is installed on the shaft diameter of the stirring shaft 7 extending out of the feed box 15.

[0032] The stirring shaft 7 is rotatably supported on the feed box 15 through the bearing seat 8. It can be understood that a plurality of stirring teeth are arranged on the shaft diameter of the stirring shaft 7, and each stirring tooth includes a stirring tooth shaft arranged to penetrate the shaft diameter of the stirring shaft 7, and a V-shaped stirring portion is fixedly connected to the axial ends of the stirring tooth shaft. When working, the stirring shaft 7 can realize reliable stirring operation for the material in the feed box 15 to achieve the purpose of uniform material.

[0033] like Figure 2 As shown, it can be understood that the bottoms of the first feeding cylinder 1 and the second feeding cylinder 16 are supported by a support seat. Figure 5 As shown, an oil seal 11 is provided at the connection between the stirring shaft 7 and the feed box 15 to achieve a reliable sealing effect.

[0034] Furthermore, a ring sleeve 25 is respectively arranged between the two first oil seals 23 and between the two second oil seals 24, and the ring sleeve 25 is evenly provided with a plurality of radial through holes along the circumferential direction, and the annular groove on the outer surface of the ring sleeve 25 is connected with the air hole provided on the corresponding bearing seat on the feed box 25. It can be understood that the radial through hole is arranged at the center of the bottom surface of the annular groove and is arranged in a circumferential shape; when working, the air hole is connected to the air pipe, and air is added therein, so that dust will not escape from here, thereby realizing a reliable airtight seal.

[0035] The present invention adopts two spirals for parallel output and a side-by-side design, which can increase the size of the material inlet and facilitate spiral pushing. The spiral outlet adopts a circular design, which is convenient for connecting with the on-site pipeline (the traditional outlet is a square outlet). It is also equipped with a feeding door, that is, a valve flap 10; it ensures that the material can be discharged evenly and stopped instantly, thereby ensuring the metering accuracy.

[0036] The spiral control can be operated simultaneously or separately. Sealing advantages: The traditional spiral adopts the front and rear bearing design. The disadvantage of this design is that the auger is prone to jumping when rotating. Many manufacturers use the larger spiral diameter to offset the jumping. The solution we adopt: the tail end adopts a double bearing design, and adopts a double oil seal and gas seal combination to achieve the auger is not easy to jump, while ensuring that dust is not easy to leak, causing bearing damage, and solving the problem of difficult on-site maintenance. The front end of the auger is also equipped with a sealing ring and a bearing as a positioning point to completely solve the jumping of the auger, making the operation more stable, improving the uniformity of conveying materials, balanced discharge, and solving the problem of inaccurate measurement. This auger design improves the measurement accuracy by 50% compared with the traditional spiral design.

[0037] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
