Embodiment Construction
[0020] Such as Figure 1 to Figure 4 As shown, the automatic unloading hopper device includes a bracket 2 and a hopper 1 for loading materials. There is a drive device that can drive the opening and closing of the left bucket door 5 and the right bucket door 4. The left bucket door 5 and the right bucket door 4 are arranged symmetrically. The lip frames 42 are in contact with each other and are located on the same central plane of the hopper 1 .
[0021] In the embodiment of the present invention, the left bucket door 5 and the right bucket door 4 are respectively provided with connecting pieces and reinforcing ribs, and the connecting pieces and the reinforcing ribs are integrated, which are respectively reinforcing rib connecting pieces 51 and 41, and reinforcing ribs The plate connector 51 is connected and fixed on the left bucket door 5 , and the reinforcing rib plate connector 41 is connected and fixed on the right bucket door 4 . The driving device includes a hinge con...

The invention relates to an automatic unloading hopper device which comprises a support and a hopper for holding materials. The hopper is fixedly connected to the support; a left hopper door and a right hopper door which can be opened and closed are arranged at the lower end of the hopper; a drive device capable of driving the left hopper door and the right hopper door to be opened and closed is arranged on the support; the left hopper door and the right hopper door are mutually symmetric, and when the left hopper door and the right hopper door are closed, a spigot frame of the left hopper door and a spigot frame of the right hopper door are contacted and located in the same central plane of the hopper. According to the automatic unloading hopper device, the left hopper door and the right hopper door are convenient to install and maintain, and the matching precision of the left hopper door and the right hopper door can be improved; each of the left hopper door and the right hopper door is provided with a connector and a reinforcing rib plate which are integrated, so that the thickness of a stainless steel plate can be reduced, the cost is reduced, and the rigidity of the left hopper door and the right hopper door cannot be reduced; a tension spring provided with a fixing hole can avoid the defect that a hook-type tension spring is prone to falling and can stably operate in a machine.
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...
