Therefore, after the material enters the device body 1, the driving mechanism 3 drives the screw conveying mechanism 2 to convey the material to the next device.

At present, a common auger feeding device pushes materials through a group of screw conveying mechanisms 2, so that the efficiency is low, the materials are easy to remain in the auger feeding device, manual treatment is needed subsequently, and the operation is complex. To solve this problem, the screw conveying mechanism 2 of this embodiment is provided with two sets of screw conveying mechanisms side by side, and the two sets of screw conveying mechanisms 2 are all arranged along the material pushing direction and push materials in the same direction. According to the double-auger feeding device, on one hand, two groups of spiral conveying mechanisms 2 are arranged in the device body 1 side by side, and on the other hand, the two groups of spiral conveying mechanisms 2 push materials simultaneously, so that the material pushing speed can be increased, and the material pushing efficiency is improved; on the other hand, the materials in the pushing device body 1 of the two groups of screw conveying mechanisms 2 can be more omnibearing, so that the material residues are not easy to occur, and manual cleaning is not needed subsequently.

The structure of the twin screw feeder of this embodiment will be described in detail.

The device body 1 comprises a shell 11 and a cover plate 12, wherein the cover plate 12 is arranged on the shell 11 in a covering manner to form a containing cavity between the cover plate 12 and the shell 11, and two groups of screw conveying mechanisms 2 are arranged in the containing cavity side by side so as to convey materials in the same direction through the two groups of screw conveying mechanisms 2.

Specifically, the housing 11 of the present embodiment has a rectangular structure, and the top surface thereof has a rectangular structure, so that the cover plate 12 is designed as a rectangular structure for better covering the housing 11. The cover plate 12 and the shell 11 can be designed into a buckle connection, a bolt connection and the like so as to prevent the cover plate 12 from loosening and falling in the material conveying process.

The device body 1 is provided with a feed inlet 13 and a discharge outlet 14, and the feed inlet 13 and the discharge outlet 14 are respectively arranged at two opposite ends of the material conveying direction. The material enters the device body 1 at the feed inlet 13, is conveyed by the two groups of screw conveying mechanisms 2, and enters the next device from the discharge outlet 14 at the other end.

The feed inlet 13 of this embodiment is disposed at the top end of the device body 1, and the discharge outlet 14 is disposed at the bottom end of the device body 1. Specifically, at one end of the material conveying direction, an opening is formed in the cover plate 12, and a feeding portion is disposed at the opening, and opposite ends of the feeding portion corresponding to the opening are of an open structure, so that a feeding port 13 is formed. At the other end in the material conveying direction, the bottom end of the housing 11 is provided with an opening penetrating the bottom of the housing 11 to form a discharge port 14.

The screw conveying mechanism 2 comprises a first screw conveying mechanism and a second screw conveying mechanism which are arranged side by side and push materials in the same direction, the first screw conveying mechanism comprises a first rotating shaft 21 and a first screw blade 22, the first screw blade 22 is fixedly sleeved on the first rotating shaft 21, the second screw conveying mechanism comprises a second rotating shaft 23 and a second screw blade 24, and the second screw blade 24 is fixedly sleeved on the second rotating shaft 23. Therefore, the first rotating shaft 21 can rotate to drive the first helical blade 22 to rotate helically, and the second rotating shaft 23 can rotate to drive the second helical blade 24 to rotate helically, so that the conveying of materials in the device body 1 is promoted.

Specifically, the two sets of screw feeding mechanisms 2 of the present embodiment are provided in the housing 11 of the apparatus body 1. Due to the structural characteristics of the first helical blade 22 and the second helical blade 24, the bottom of the housing 11 of the present embodiment is an arc-shaped structure adapted to the first helical blade 22 and the second helical blade 24, so as to avoid the first helical blade 22 and the second helical blade 24 from loosening due to large shake generated by the first helical blade 22 and the second helical blade 24 in the process of conveying materials. At the same time, the direction of transport of the material can be defined to a certain extent so that the material can be transported from the discharge opening 14 to the next device quickly.

It should be noted that the rotation direction of the first rotation shaft 21 and the first screw blade 22, and the rotation direction of the second rotation shaft 23 and the second screw blade 24 need to ensure that the material can be pushed from the feed port 13 to the discharge port 14.

Further, one end of the first helical blade 22 is sleeved on the first rotating shaft 21, and the first helical blade and the second helical blade synchronously rotate, and one end of the second helical blade 24 is sleeved on the second rotating shaft 23, and the first helical blade and the second helical blade synchronously rotate. Since the first rotating shaft 21 and the second rotating shaft 23 are only arranged at the end parts, when the screw conveying mechanism 2 conveys materials, the materials are pushed through the screw rotation of the first screw blade 22 and the second screw blade 24, the first rotating shaft 21 and the second rotating shaft 23 are basically not contacted with the materials, the material pushing speed is increased, and the materials are not attached to the first rotating shaft 21 and the second rotating shaft 23, so that the material residues are avoided.

On the basis, the first rotating shaft 21 and the second rotating shaft 23 are provided with one end of the feeding hole 13, so that the contact between the first rotating shaft 21 and the second rotating shaft 23 and materials is further reduced.

The driving mechanism 3 comprises a driving motor 31 and an output shaft 32, one end of the output shaft 32 is connected with the output end of the driving motor 31, the other end of the output shaft 32 is connected with the screw conveying mechanism 2, and the output end of the driving motor 31, the output shaft 32 and the screw conveying mechanism 2 synchronously rotate. Therefore, the driving motor 31 drives the output shaft 32 and the screw conveying mechanism 2 to synchronously rotate, so that the screw conveying mechanism 2 conveys materials. In practical applications, care should be taken to control the rotation direction of the output shaft 32 by the driving motor 31 to ensure that the screw conveyor 2 can push the material from the inlet 13 to the outlet 14.

In the first embodiment, the driving motor 31 includes a first driving motor and a second driving motor, the output shaft 32 includes a first output shaft and a second output shaft, one end of the first output shaft is fixedly connected with the output end of the first driving motor, the other end of the first output shaft is fixedly connected with the first rotating shaft 21, one end of the second output shaft is fixedly connected with the output end of the second driving motor, and the other end of the second output shaft is fixedly connected with the second rotating shaft 23. Thus, the first driving motor drives the first output shaft and the first rotating shaft 21 to synchronously rotate, so that the first helical blade 22 is driven to rotate to push materials, and the second driving motor drives the second output shaft and the second rotating shaft 23 to synchronously rotate, so that the second helical blade 24 is driven to rotate to push materials.

It should be noted that in this embodiment, the two sets of screw conveying mechanisms 2 need to ensure that the directions of conveying materials are the same, but there is no requirement for the conveying speed, and the conveying speeds can be the same or different, and are determined according to practical situations.

In this embodiment, when the first and second drive motors rotate in the same direction, the helical directions of the first and second helical blades 22, 24 are the same, so that the first and second helical blades 22, 24 push material in the same direction.

When the first and second drive motors are rotated in opposite directions, the first and second helical blades 22, 24 are rotated in opposite directions so that the first and second helical blades 22, 24 push material in the same direction.

In the second embodiment, two output shafts 32 are arranged side by side and fixedly connected with the first rotating shaft 21 and the second rotating shaft 23 respectively, gears 33 are sleeved on the two output shafts 32, the two gears 33 are meshed with each other, and the spiral directions of the first spiral blade 22 and the second spiral blade 24 are opposite.

In this embodiment, since the gears 33 on the two output shafts 32 are meshed, the rotation directions of the two gears 33 are opposite, so that the rotation directions of the conveying shaft 32, the first rotating shaft 21 and the first helical blade 22 of the first helical conveying mechanism are opposite to the rotation directions of the conveying shaft 32, the second rotating shaft 23 and the second helical blade 24 of the second helical conveying mechanism, the helical directions of the first helical blade 22 and the second helical blade 24 are opposite, so that the first helical blade 22 and the second helical blade 24 can push the materials in the same direction, and at least two groups of helical conveying mechanisms 2 can convey the materials in the same direction.

In this embodiment, since the two sets of screw conveyors 2 are driven by one driving motor 31, when the number of teeth of the two gears 33 is the same, the two sets of screw conveyors 2 are required to convey the material in the same direction and simultaneously convey the material at the same speed. When the number of teeth of the two gears 33 is different, the two sets of screw conveying mechanisms 2 convey materials in the same direction and simultaneously convey materials, but the conveying speeds are different.

The technical means disclosed by the scheme of the utility model is not limited to the technical means disclosed by the embodiment, and also comprises the technical scheme formed by any combination of the technical features. It should be noted that modifications and adaptations to the utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
