Description

Technical Field

[0001] This utility model belongs to the field of sorting equipment technology, and in particular relates to a double-helix material sorting and conveying device. Background Technology

[0002] Currently, in the production of certain granular materials, pulverizing devices are sometimes used to crush lumpy materials into granular materials. However, since the granular materials formed during the crushing process are of different sizes, sorting and conveying devices are needed to transport and screen the granular materials to distinguish granular materials of different sizes.

[0003] Existing sorting and conveying devices are usually vibrating screens. When in use, granular materials are poured into the inclined screen boxes of the vibrating screen. Under the action of the vibrating motor, the granular materials can be screened and conveyed at the same time. However, with the above method, sometimes after the granular materials fall to the lower side of the screen box, they need to be added back into the screen box and screened multiple times to improve the sorting effect. This is quite troublesome to use. Therefore, there are still shortcomings and deficiencies in the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide a double-helix material sorting and conveying device to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows:

[0006] A double-helix material sorting and conveying device includes four vertically opposite support legs, and a horizontally distributed sorting box is installed between the tops of the four support legs. The sorting box is a box structure with a cavity, and one end of the sorting box along its length is fixedly connected to a feed hopper located at the top of the sorting box. The other end of the sorting box along its length is provided with a discharge port located at the bottom of the sorting box, and the discharge port is provided with an openable and closable door.

[0007] The sorting box is also fixedly connected with vertically distributed partitions. The two ends of the partitions are spaced apart from the two ends of the sorting box along its length to form a communication port. The partitions divide the sorting box into two sorting chambers of the same size and connected through the communication port. The vertical cross-section of the sorting chamber is circular. The bottom of each sorting chamber is provided with several sorting through holes. Each sorting chamber is also rotatably connected to a spiral conveyor rod arranged parallel to the length of the sorting box. The two spiral conveyor rods share a set of drive mechanisms and rotate in opposite directions.

[0008] Furthermore, each sorting chamber is fixedly connected to a blower at one end, with two blowers arranged diagonally, and the air outlets of each blower are horizontally distributed and respectively opposite to the position of the connecting port.

[0009] Furthermore, the door is located below the sorting box, and one side of the door is hinged to the sorting box. The other side of the door is provided with an inclined electric telescopic rod. The side of the electric telescopic rod closest to the door is hinged to the door, and the other side of the electric telescopic rod is hinged to a support plate that is vertically installed on the sorting box.

[0010] Furthermore, a spring is installed between the top of each leg and the sorting box, and the spring and the leg are arranged on the same axis. A vibration motor is installed on the sorting box.

[0011] Furthermore, two vertically distributed second electric telescopic rods are installed in the two support legs located away from the material discharge port. The top of the second electric telescopic rod is the telescopic end and is located outside the support leg. The telescopic end of the second electric telescopic rod is hinged to a support for supporting the spring.

[0012] Furthermore, each spiral conveyor rod has a transmission gear mounted on one end after passing through the sorting box. The two transmission gears mesh with each other, and a housing mounted on the sorting box is mounted on both transmission gears. The drive mechanism includes a drive motor mounted on the housing, and the output shaft of the drive motor is connected to one of the spiral conveyor rods.

[0013] The beneficial effects of this utility model by adopting the above technical solution are as follows:

[0014] This invention, by setting up a partition and opening a connecting port, divides the sorting box into two interconnected sorting chambers. Each sorting chamber is equipped with a screw conveyor, and the two screw conveyors rotate in opposite directions. In use, under the action of the screw conveyors, the granular material to be sorted can be circulated and conveyed along the circumference of the sorting box. At the same time, during the conveying of granular material, small granular materials can be screened multiple times through the sorting through holes. Therefore, compared with the prior art, it can improve the sorting effect without the granular material having to go through multiple feeding and unfeeding processes, making it more convenient to use.

[0022] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] like Figures 1 to 6 As shown, this utility model provides a double-helix material sorting and conveying device, including four vertically opposite support legs 8. A horizontally distributed sorting box 5 is installed between the top ends of the four support legs 8. The sorting box 5 is a box structure with a cavity, and one end of the sorting box 5 in the length direction is fixedly connected to a feed hopper 13 located at the top of the sorting box 5. In use, the granular material to be sorted can be added into the sorting box 5 through the feed hopper 13. The other end of the sorting box 5 in the length direction is provided with a discharge port 51 located at the bottom of the sorting box 5. The discharge port 51 is provided with a box door 52 that can be opened and closed. Specifically, in use, when the box door 52 is opened, the large granular material after sorting can be discharged.

[0024] In addition, vertically distributed partitions 2 are fixedly connected inside the sorting box 5. The two ends of the partitions 2 are spaced apart from the two ends of the sorting box 5 along its length to form a communication port 3. The partitions 2 divide the sorting box 5 into two sorting chambers 4 of the same size and connected through the communication port 3. The vertical cross-section of the sorting chambers 4 is circular. Each sorting chamber 4 has several sorting through holes 41 at its bottom. Each sorting chamber 4 is also rotatably connected to a spiral conveying rod 1 that is parallel to the length of the sorting box 5. The two spiral conveying rods 1 share a set of drive mechanisms 10 and rotate in opposite directions. Specifically, in use, under the action of the spiral conveying rods 1, the granular material to be sorted can be circulated and conveyed along the circumference of the sorting box 5. At the same time, during the conveying of granular material, small granular materials can be screened multiple times through the sorting through holes 41. Therefore, compared with the existing technology, the granular material does not need to go through multiple feeding and unfeeding processes, and the sorting effect can be improved, making it easier to use.

[0025] To prevent granular materials from clogging the connection port 3, therefore, as Figure 3 As shown, a blower 6 is fixedly connected to one end of each sorting chamber 4. The two blowers 6 are arranged diagonally, and the air outlets of each blower 6 are horizontally distributed and opposite to the position of the connecting port 3. Specifically, when in use, by starting the blower 6, the granular material located at the connecting port 3 can be blown into the sorting chamber 4, so that the granular material can be circulated and conveyed along the circumference of the sorting box 5. At the same time, it can prevent the granular material from being blocked at the connecting port 3.

[0026] The specific design of the door 52, which can be opened and closed, is as follows: Figure 1 , Figure 2 and Figure 6 As shown, the door 52 is located below the sorting box 5, and one side of the door 52 is hinged to the sorting box 5. The other side of the door 52 is provided with an inclined first electric telescopic rod 14, which can be configured as an electric push rod. The side of the first electric telescopic rod 14 closest to the door 52 is hinged to the door 52, and the other side of the first electric telescopic rod 14 is hinged to a support plate 15 vertically installed on the sorting box 5. Specifically, the support plate 15 is located outside the hinge side of the door 52 and the sorting box 5. In the initial state, the telescopic end of the first electric telescopic rod 14 is in the extended state, at which time the door 52 can seal the discharge port 51. When the telescopic end of the first electric telescopic rod 14 is retracted, the door 52 can open the discharge port 51 and can make the door 52 inclined to facilitate material discharge. At this time, under the action of the screw conveyor 1, large granular materials can be conveyed to the position of the discharge port 51 for discharge.

[0027] To improve the sorting efficiency of granular materials, therefore, such as Figure 1 and Figure 6As shown, a spring 7 is installed between the top of each support leg 8 and the sorting box 5. The spring 7 is the same as the spring in the existing vibrating screen. The spring 7 and the support leg 8 are set on the same axis. A vibrating motor 9 is installed on the sorting box 5. Specifically, when the vibrating motor 9 is started, the sorting efficiency of granular materials can be improved under the action of the vibrating motor 9 and the spring 7.

[0028] Furthermore, such as Figure 1 , Figure 2 and Figure 6 As shown, two vertically distributed second electric telescopic rods 16 are installed in the two support legs 8 located away from the material discharge port 51. The second electric telescopic rods 16 can be configured as electric push rods. The top of the second electric telescopic rod 16 is the telescopic end and is located outside the support leg 8. The telescopic end of the second electric telescopic rod 16 is hinged to a support 17 for supporting the spring 7. Specifically, in the initial state, the telescopic end of the second electric telescopic rod 16 is in the retracted state. At this time, the sorting box 5 is horizontally distributed. In the latter half of the material discharge, the second electric telescopic rod 16 is slowly extended through the telescopic end. The sorting box 5 can be tilted closer to the discharge port 51 to facilitate complete material discharge. At this time, the sorting through-hole 41 can also be purged by an external air gun to prevent blockage. In addition, during the sorting of granular materials, the sorting box 5 can be tilted closer to the discharge port 51 according to the actual use to allow the granular materials at the bottom of the sorting chamber 4 to flow. Furthermore, the vertical cross-section of the discharge port 51 can be set as a conical structure with a wider top and narrower bottom, which makes it easier for large granular materials to fall from the discharge port 51 after sorting.

[0029] The specific arrangement of the two screw conveyor rods 1 rotating in opposite directions is as follows: Figure 1 , Figure 5 and Figure 6 As shown, each spiral conveyor rod 1 has a transmission gear 11 mounted on one end after passing through the sorting box 5. The two transmission gears 11 mesh with each other, and a housing 12 mounted on the sorting box 5 is mounted on both transmission gears 11. The drive mechanism 10 includes a drive motor mounted on the housing 12. The output shaft of the drive motor is connected to one of the spiral conveyor rods 1. Specifically, the output shaft of the drive motor and one of the spiral conveyor rods 1 are coaxially arranged and connected by a coupling. In use, when the drive motor is started, the two spiral conveyor rods 1 can be synchronously driven to rotate in opposite directions under the action of the two transmission gears 11.
