Hopper device with automatic discharge achievable

Abstract

The invention relates to a hopper device with automatic discharge achievable. The hopper device with the automatic discharge achievable comprises a support and a hopper used for containing materials, wherein the hopper is connected and fixed on the support, a left hopper door and a right hopper door are arranged at the lower end of the hopper, the left hopper door and the right hopper door can be opened and closed, a driving device used for driving opening and closing of the left hopper door and the right hopper door is arranged on the support, the left hopper door and the right hopper door are arranged symmetrically, and when the left hopper door and the right hopper door are closed, a rabbet border of the left hopper door is in contact with a rabbet boarder of the right hopper door, and the seam border of the left hopper door and the seam border of the right hopper door are located on the same central surface of the hopper. According to the hopper device with the automatic discharge achievable, the left hopper door and the right hopper door can be installed and maintained conveniently, and matching accuracy of the left hopper door and the right hopper door is improved; integral connection pieces and reinforcing ribs are arranged on the left hopper door and on the right hopper door, and therefore thickness of a stainless steel plate is reduced, cost is reduced, and rigidity of the left hopper door and the right hopper door is not reduced; and a tension spring with a fixing hole is arranged to solve the problem that a hook type tension spring is easy to fall off, and stability of the tension spring when a machine is in operation is ensured.

Description

technical field [0001] The invention relates to a mechanical hopper device, in particular to a hopper device for a combined automatic weighing machine. Background technique [0002] At present, the existing automatic unloading hopper device for combined stalks on the market mainly includes a bracket and a hopper for loading materials. The hopper is fixedly installed on the bracket. There is a driving device, which can drive the front and rear doors to open and close. Connecting pieces are respectively installed on both sides of the left bucket door and the right bucket door. The four connecting pieces are connected with the driving device on the bracket through a hinge mechanism. Usually, when the left bucket door and the right bucket door are closed, the seam edge of the right bucket door is located inside the seam edge of the left bucket door, so that during the manufacturing or installation process, the matching accuracy of the left and right bucket doors is very high, an...

AI Technical Summary

Problems solved by technology

Usually, when the left bucket door and the right bucket door are closed, the seam edge of the right bucket door is located inside the seam edge of the left bucket door, so that during the manufacturing or installation process, the matching accuracy of the left and right bucket doors is very high, and it is also necessary for future maintenance of the left and right bucket doors Inconvenient; In addition, in order to prevent the left and right bucket doors from being deformed during long-term use, the thickness of the stainless steel plate used is relatively large, and the cost is relatively high
