Embodiment Construction
[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the drawings and embodiments of the embodiments of the present invention.
[0025] See figure 1 , is a structural schematic diagram of the opening and closing control device for the hopper door provided by the embodiment of the present invention. Such as figure 1 The illustrated opening and closing control device for the hopper door includes: a connection module 11 and a limit guide rail 12; this device can be used to automatically control the opening and closing of the hopper door 13 during the movement of the hopper 10, and the opening and closing performance is safe. reliable. Wherein, the hopper door 13 passes through the pin ( figure 1 Not shown in ) is fixedly connected on the hopper 10.
[0026] The connection module 11 is co...

The invention provides an opening and closing control device of hopper doors. The opening and closing control device of the hopper doors comprises connection modules 11 and limiting guide rails 12, wherein the connection modules 11 are connected with the hopper doors 13 and rolling wheels 14, and the rolling wheels 14 make contact with the corresponding limiting guide rails 12 and move along the corresponding guide rails 12. By means of application of the opening and closing control device of the hopper doors, the purpose that opening and closing of the hopper doors 13 are automatically controlled in the moving process of hoppers 10 can be achieved, and opening and closing performance is safe and reliable.
Description
technical field [0001] The present application relates to the technical field of hopper equipment, in particular to an opening and closing control device for a hopper door. Background technique [0002] At present, in one solution, the opening and closing of the hopper door can be controlled by a device composed of a cylinder (or oil cylinder) and a connecting rod mechanism. Specifically, the opening and closing of the hopper door can be controlled by controlling the expansion and contraction of the cylinder (or oil cylinder); In another solution, the opening and closing of the hopper door can be controlled by a device composed of an electric push rod and a linkage mechanism. Specifically, the opening and closing of the hopper door can be controlled by controlling the expansion and contraction of the electric push rod. [0003] However, on the one hand, for the device composed of the cylinder (or oil cylinder) and the connecting rod mechanism, the power source needs to be co...
