Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of valves, and in particular relates to a discharge valve for a transfer hopper. Background Art
[0002] Material conveying equipment involves the transfer of granular materials, powdered materials, and liquid materials. The materials enter the transfer hopper after being weighed and are transported to the material bin by the transfer hopper. The commonly used transfer hopper has an upper inlet and lower outlet method. During the material transfer process, the lower outlet valve of the transfer hopper is in the closed position. Since the transfer hopper is a moving part, it is not convenient to install pneumatic valves or electric valves on the lower outlet valve of the transfer hopper. The use of manual valves results in high labor intensity and low efficiency for operators. Therefore, how to reduce the labor intensity of operators and improve the degree of automation of equipment has become a technical problem that needs to be solved urgently. Summary of the invention
[0003] The technical problem to be solved by the utility model is to provide a discharge valve for a transfer hopper. By improving the valve control structure, there is no need to add pneumatic, electric or other power devices to the transfer hopper, which can make the design of the transfer hopper moving device simpler and improve the degree of automation of the discharge valve.
[0004] The technical solution adopted by the utility model is: a discharge valve for a transfer hopper, including a valve plate arranged at the outlet of the transfer hopper by means of a rotating shaft, a valve plate control box is arranged on the outer wall of the outlet of the transfer hopper, a gear connected to the rotating shaft, and a rack matched with the gear by means of a guide rail are arranged in the valve plate control box, one end of the rack is connected to a brake cylinder connector arranged on the outside of the valve plate control box, and the other end is connected to a reset mechanism arranged in the valve plate control box; the connecting end of the brake cylinder connector is connected to the brake cylinder at the discharge station.
[0005] Furthermore, the reset mechanism includes a reset plate connected to the rack, a reset guide tube group arranged on the inner wall of the valve plate control box, a mounting column group arranged on the reset plate, and a reset spring sleeved on the mounting column, and the other end of the reset spring is arranged in the reset guide tube.
[0006] The beneficial effects produced by adopting the utility model are as follows: by improving the valve control structure, there is no need to add pneumatic, electric or other power devices to the transfer hopper, the design of the transfer hopper moving device can be made simpler, and the automation degree of the unloading valve is improved.

DETAILED DESCRIPTION
[0010] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.
[0011] See attached Figure 1 , a discharge valve for a transfer hopper, comprising a valve plate provided at the outlet of the transfer hopper 7 by means of a rotating shaft 7-1, a valve plate control box 7-2 provided on the outer wall of the outlet of the transfer hopper 7, a gear 7-3 connected to the rotating shaft 7-1, and a rack 7-4 matched with the gear 7-3 by means of a guide rail 7-5 provided in the valve plate control box 7-2, one end of the rack 7-4 is connected to a brake cylinder connector 7-6 provided on the outside of the valve plate control box 7-2, and the other end is connected to a reset mechanism provided in the valve plate control box 7-2; the connection end of the brake cylinder connector 7-6 is connected to the brake cylinder 10 at the discharge station. The reset mechanism comprises a reset plate 7-7 connected to the rack 7-4, a reset guide tube 7-8 set on the inner wall of the valve plate control box 7-2, a mounting column 7-9 set on the reset plate 7-7, and a reset spring 7-10 sleeved on the mounting column 7-9, and the other end of the reset spring 7-10 is provided in the reset guide tube 7-8. See the attached Figure 2 In this embodiment, four mounting posts 7-9, four return springs 7-10, and four return guide tubes 7-8 are provided. The gear is assembled on the shaft of the discharge valve; the gear and the rack are meshed with each other; the rack and the return spring are installed in the fixed box.
[0012] During the specific implementation, the transfer hopper 7 is moved into place and comes to rest, and the telescopic rod of the brake cylinder 10 is connected to the brake cylinder connector 7-6, which in turn pushes the rack 7-4 to rotate the gear 7-3. The rotation of the gear 7-3 drives the valve plate to open. After the brake cylinder 10 reaches the maximum stroke, the valve plate is fully opened, and the material in the transfer hopper 7 flows out.
[0013] After the material in the transfer hopper 7 has flowed out, the telescopic rod of the brake cylinder 10 contracts, and then under the restoring force of the reset spring 7-10, the reset plate 7-7 pushes the rack 7-4, and the gear 7-3 rotates to drive the valve plate to close; the transfer hopper 7 moves out of the unloading position.
[0014] The utility model does not need to add pneumatic, electric or other power devices to the transfer hopper 7, so the design of the moving device of the transfer hopper 7 can be more concise.
[0015] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or partially or completely modify them.
[0016] The technical features are replaced by equivalents; however, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the various embodiments of the utility model.
