Sensor

Abstract

The invention provides a sensor. The sensor comprises a threaded rod, a thin shaft bracket, a main sensor, an anti-collision sensor and a processing unit, wherein the thin shaft bracket is arranged atthe top of the threaded rod, the main sensor comprises a roller, a threaded sleeve and a sleeve shaft, the roller sleeves one end of the sleeve shaft, the threaded sleeve is connected to the bottom of the sleeve shaft and sleeves the threaded rod, and the thin shaft bracket penetrates through the sleeve shaft. The anti-collision sensor comprises an anti-collision installing plate, an anti-collision roller, an anti-collision wheel axle and an anti-collision boom, the anti-collision boom is hinged to the top of the anti-collision installing plate, one end of the anti-collision wheel axle is connected to the anti-collision boom, the other end of the anti-collision wheel axle is connected to the anti-collision roller, the anti-collision installing plate is provided with a first fixing hole and a second fixing hole, the first fixing hole is matched with the threaded rod, and the second fixing hole is matched with the thin shaft bracket. The processing unit is in communicated connection with the main sensor and the anti-collision sensor. The sensor can detect the surface linear speed of a rolling object.

Description

technical field [0001] The invention belongs to the field of measurement and detection, and more specifically relates to a sensor. Background technique [0002] With the current population increase, the demand for food supply is increasing. According to the field investigation and the feedback from the staff of the grain factory, the key components currently used for shelling are two large rubber rollers with the same initial radius, and the rice huller works in three shifts and works 24 hours a day, so the rubber rollers It causes a lot of wear and tear. Generally, the working life of this kind of rubber roller is changed every 3-6 days, and the distance between the shafts of the two rubber rollers needs to be adjusted manually on a regular basis. The distance between the opposing surfaces of the two rubber rollers must be strictly controlled. Because it is related to the hulling rate and yield of rice. Therefore, the traditional rice huller has low production efficiency,...

AI Technical Summary

Problems solved by technology

Therefore, the surface linear velocity of the two rubber rollers should remain unchanged, but how to detect the surface linear velocity of rolling objects is still a difficult problem in the industry
