Self-locking medicine weighing hopper

Abstract

The invention relates to a self-locking medicine weighing hopper. A hopper body is mounted on a hopper positioning bracket, one end of a fixed bar is connected to the hopper body, a connecting rod A is hinged to the other end of the fixed bar, one end of the connecting rod A is a free end while the other end of the connecting rod A is hinged to one end of a connecting rod B through a main push shaft, the other end of the connecting rod B is hinged to one end of a connecting rod C hinged to the hopper body, the other end of a connecting rod C is hinged to one end of a connecting rod D, the other end of the connecting rod D is hinged to one end of a connecting rod E, the other end of the connecting rod E is hinged to the hopper body, and hopper turnplates are separately mounted on the connecting rods E and C; a spring guide bar is mounted on the hopper body, a self-locking push plate is slidably connected to the spring guide bar, a reset spring is arranged on the spring guide bar in a sleeving manner, and two ends of the reset spring are in abut joint to the hopper body and the self-locking push plate, separately. The self-locking medicine weighing hopper can open and close the hopper under the action of an external push force mechanism, and the hopper turnplates can be reset automatically to a folded state when the external force is withdrawn. The connecting rods are self-lockedstably, so that weighed medicine particles in the hopper do not leak.

Description

technical field [0001] The invention relates to a weighing hopper system, in particular to a self-locking weighing hopper. Background technique [0002] The weighing hopper is a passive hopper used to complete the weighing and filling of explosives. When the weighing hopper is working, the hopper can be placed on the mass weighing device by an external mechanism, and the inside of the hopper can be injected online. After the weighing and injection is completed, the external mechanism will move it to the drug dropping station, and the external mechanism The lower opening and closing of the weighing hopper completes the work of dropping the medicine. At present, most of the weighing hoppers in China have complex structures, which require an external multi-degree-of-freedom mechanism to realize the opening and closing of the hopper. This kind of weighing hopper has the following disadvantages: first, the external mechanical structure is complex, and the manufacturing cost of ...

AI Technical Summary

Problems solved by technology

At present, most of the domestic weighing hoppers have complex structures and require external multi-degree-of-freedom mechanisms to realize the opening and closing of the hoppers

This kind of weighing hopper has the following disadvantages: first, the external mechanical structure is complicated, and the manufacturing cost of the mechanism is high; second, during the process of opening and closing the external mechanical structure, the positioning accuracy of the hopper is high. Larger, the external mechanism may fail to open and close the hopper; third, the reliability of hopper closing is low, and material leakage is prone to occur

[0003] In the field of automatic filling of explosives and explosives in China, there is no weighing hopper that can be opened and self-locked under the action of an external single-degree-of-freedom mechanism. The opening and closing mechanism of the weighing hopper at this stage is complicated, the mass production cost is high, and the reliability of the opening and closing mechanism is low. , cannot meet the requirements of high reliability and economy in the field of automatic loading of propellants and explosives
