Technical Field
[0001] This utility model belongs to the field of hydraulic guide bar unloading gates, specifically relating to a hydraulic guide bar unloading gate. Background Technology
[0002] A hydraulic guide bar type unloading gate is a device that uses the pressure of hydraulic oil to provide power to drive the gate to open and close. The guide bar mechanism plays a guiding and supporting role, ensuring that the gate moves smoothly along a predetermined trajectory during movement and guaranteeing the accurate opening and closing position of the unloading gate.
[0003] However, there are two main types of unloading gates for existing double-disc mixing coolers: counterweight type and electric push rod type. As the name suggests, the opening and closing of the unloading gate is entirely controlled by the counterweight. That is, when the pressure of the sand is greater than the weight of the counterweight, the unloading gate opens; when the pressure of the sand is less than the weight of the counterweight, the unloading gate closes. The disadvantage of the counterweight type is that it cannot control the opening and closing of the unloading gate of the double-disc mixing cooler. Compared with the counterweight type, the electric push rod type achieves precise control of the opening and closing of the unloading gate, but the biggest problem it brings is that the unloading gate is very easy to jam when the electric push rod is working in a dirty working environment. Once the unloading gate jams, the electric push rod will burn out due to excessive current, causing great trouble for users. In order to solve the problems of the existing devices, there is an urgent need for a convenient and efficient hydraulic guide rod type unloading gate. Utility Model Content
