Description

Technical Field

[0001] The utility model relates to the technical field of cone feeding, in particular to a pneumatic mechanism and a cone feeding device thereof. Background Art

[0002] In industrial production, conical silos are generally used as buffer silos and feeding devices to ensure the continuity of industrial production. In actual applications, traditional conical silo feeding devices have the following defects: high-density, large-particle materials can slide out of the feed port under their own gravity, but powders with lower density and specific gravity tend to harden and adhere to the silo wall, making it difficult to slide down. In particular, powders with high water content tend to harden and clog the feed port during feeding, seriously hindering the continuity of feeding and requiring operators to perform long-term unblocking operations, reducing work efficiency. At the same time, the existing barrel installed in the conical feeding device cannot accurately control its feeding level. Utility Model Content

[0003] In order to solve the above technical problems, one of the technical solutions adopted by the present invention is: a pneumatic mechanism, which is used to push open the barrel installed on the conical feeding device, allowing the material to enter the discharge port of the conical feeding device to complete quantitative discharge; the mechanism includes:

[0004] Support wire tube 1, which is installed in the feeding port;

[0005] The cylinder mounting housing 2 is located in the feed opening; the mounting housing is supported and mounted in the feed opening by the support wire tube 1;

[0006] A stroke cylinder 3, which is mounted in the cylinder mounting housing 2;

[0007] The top seat 4 is installed on the telescopic end of the stroke cylinder 3; it is used to open the conical bottom valve of the barrel so that the material in the barrel can enter the discharge port.

[0008] Furthermore, the supporting wire tube 1 is a hollow square wire tube that is set at an angle, so that the materials dropped on the supporting wire tube 1 can fall down easily.

[0009] Furthermore, the mechanism also includes: a stroke measuring unit 5, which is used to measure the telescopic length of the stroke cylinder 3 and control the opening and closing degree of the conical bottom valve.

[0011] A movable cover 501, the upper end of which is mounted on the lower end of the top seat 4;

[0012] A hook member 502, one end of which is fixedly mounted on the lower end of the movable cover 501;

[0013] The other end of the hook 502 is mounted on one end of the measuring plate 503;

[0014] Height signal feedback device 504;

[0015] Among them, the stroke cylinder 3 drives the movable cover 501 to move up and down, hooks the measuring plate 503 to move up and down, and the height signal feedback device 504 senses the measuring point on the measuring plate 503, feeds back the extension and contraction length of the stroke cylinder 3, and controls the opening and closing degree of the conical bottom valve.

[0016] Furthermore, the mechanism also includes: at least one vibrator 6, which is installed on the support wire tube 1 and is used to vibrate the material dropped on the support wire tube 1 into the discharge port.

[0017] Another technical solution adopted by the present invention is: a conical feeding device, which includes the above-mentioned pneumatic mechanism.

[0018] The advantages and positive effects of this utility model are as follows: the stroke cylinder 3 drives the top seat 4 to open the conical bottom valve of the barrel, allowing the material in the barrel to enter the discharge port. At the same time, the stroke cylinder 3 drives the movable cover 501 to move up and down, hooking the measuring plate 503 to move up and down. The height signal feedback device 504 senses the measuring point on the measuring plate 503, and feedback is provided on the extension and contraction length of the stroke cylinder 3 to control the opening and closing degree of the conical bottom valve.
