Abstract

The invention provides a spiral propeller of a grain heap.The spiral propeller comprises a drive mechanism, a guide mechanism and a drilling mechanism; the power output end of the drive mechanism is in transmission connection with power input end of the drilling mechanism, the drive mechanism comprises a positive and negative rotating motor, a speed reducer and a steel wire soft shaft, the power output end of the positive and negative rotating motor is in transmission connection with the power input end of the speed reducer, and the power output end of the speed reducer is in transmission connection with the power input end of the steel wire soft shaft.The guide mechanism comprises a supporting frame and a pulley rotatably arranged on the supporting frame, and the steel wire soft shaft winds around a pulley groove of the pulley; the drilling mechanism comprises a conical spiral auger, a conical tip, a rolling bearing, a casing pipe and a connection shaft arranged in the casing pipe, the casing pipe and the connection shaft are arranged in the vertical direction, and the casing pipe is internally provided with a connection cavity, a bearing seat and a through hole in sequence from top to bottom.The spiral propeller is reasonable in design and simple in structure, the drive mechanism is provided, and the steel wire soft shaft drives the drilling mechanism so that the drilling mechanism can advance deeply in the grain heap.

Description

technical field [0001] The invention belongs to the technical field of grain reserve detection equipment, in particular to a grain pile screw propeller. Background technique [0002] Grain resources are an important foundation for rejuvenating the country. With the increase in my country's grain production and the improvement of people's living standards, high standards have been set for the scale and quality of grain storage. Therefore, the grain storage capacity of large and medium-sized grain reserve warehouses and free grain depots of grain processing enterprises in various parts of my country has been greatly increased, which puts forward higher requirements for grain condition detection and grain storage safety in the process of grain storage. [0003] During the storage process, the grain must always be kept in a safe storage state, and the environmental parameters such as temperature and humidity inside the grain pile should be detected in real time, so that measures...
