Flexible bidirectional limiting mechanism for stock bin door

Abstract

The invention discloses a flexible bidirectional limiting mechanism for a stock bin door. The flexible bidirectional limiting mechanism comprises a bottom cover, a threaded connection unit, a guide unit and a buffering unit, wherein a speed reducing motor and a screw rod output shaft which are connected with each other are arranged in the bottom cover, one end of the threaded connection unit extends into the bottom cover and is in threaded connection with the lead screw output shaft, the other end of the threaded connection unit is connected with a bin door baffle, the guide unit is arranged on the threaded connection unit, the guide unit can provide guidance for movement of the threaded connection unit in the bottom cover, and the buffering unit can provide buffering for movement of the threaded connection unit in the bottom cover. The structure is exquisite, parts are simple and are tightly matched, and bidirectional mechanical limiting is achieved through cooperation of elastic potential energy of a spring of the buffer unit and a screw rod thread structure of the threaded connection unit; and the device has the advantages of simple disassembly and manufacture, low cost and the like.

Description

technical field [0001] The invention relates to the technical field of a hopper door of an aquaculture bait feeder, in particular to a flexible bidirectional limiting mechanism for a hopper door. Background technique [0002] With the scientific and modularization of the modern aquaculture industry, the application of automatic bait feeding equipment is becoming more and more common. The bait feeding bin is an important part of the automatic bait feeding equipment. Therefore, the performance of the bin door limit mechanism is particularly important. [0003] The following problems exist in the use of traditional electronic limit switches: (1) The environmental conditions of the breeding pond are relatively harsh, and harsh working environments such as high temperature, extreme cold, heavy rain, lightning strikes, and dust often cause the electronic limit control switch to fail; (2) 1. During the feeding process of the silo, it is often accompanied by equipment vibration, wh...

Problems solved by technology

[0003] The following problems exist in the use of traditional electronic limit switches: (1) The environmental conditions of the breeding pond are relatively harsh, and harsh working environments such as high temperature, extreme cold, heavy rain, lightning strikes, and dust often cause the electronic limit control switch to fail; (2) 1. During the feeding process of the silo, it is often accompanied by equipment vibration, which causes the elastic switch of the limit mechanism, the paddle and other components to shift, deform, etc., and cannot work stably.

The non-electronic limit mechanism often has precise parts, complex structure, large space occupation and high cost, so it cannot be applied to the control of the bait feeding bin door
