A bionic screw robot for information detection in a granary

Abstract

The invention discloses a bionic screw robot for information detection in a granary, which comprises: a shell; at least three sets of screw propellers, which include a grain inlet and a grain outlet, and the screw propellers can suck the grain at the grain inlet after rotating. And it is discharged from the grain outlet to realize the advancement of the screw propeller in the granary; the sensor group is arranged on the outside of the shell to detect the ecological information of the grain in the granary. Wherein the screw propeller includes: a transmission shaft, which is set in a hollow shape with openings at both ends, and the transmission shaft can rotate relative to the housing; a spiral body, which is set in the hollow part of the transmission shaft; a driving motor, which passes The pair of meshing gears drives the transmission shaft to rotate. Real-time information on grain conditions can be obtained through remote control, which saves the work of arranging temperature measuring cables in the granary. It reduces the manpower and material operating costs of the granary. And it fundamentally solves the problem of difficult wiring in the granary and the interference of the temperature measuring cable on the operation of entering and exiting the grain.

Description

technical field [0001] The invention relates to the technical field of granary grain situation detection, in particular to a bionic screw robot for information detection of the granary. Background technique [0002] In the field of grain storage, the current technical means of obtaining grain data is relatively backward, and the development is slow, mainly relying on the pre-buried temperature measuring cables and temperature and humidity sensors in the granary. However, the installation of grain monitoring sensors is relatively difficult, no matter whether it is mounted before loading or buried with special tools after loading. And the volume of the sensor is not easy to be too large, and now generally only the temperature measuring cable is buried, and the installation of the humidity and gas sensors is extremely inconvenient. At the same time, the measurement cable needs to meet the requirements of corrosion resistance and tensile resistance. In practical applications, ...

AI Technical Summary

Problems solved by technology

In the process of loading and unloading grain, due to the complex wiring in the granary, failures are prone to occur, resulting in the failure of the grain monitoring system. The layout and maintenance costs of the grain monitoring system are high, and the overly complicated wiring will affect the ventilation operation. And because the cable covers a large area, it is easily damaged by lightning strikes

"Wireless" communication also has its own disadvantages, not only the network bandwidth problem, but also the energy consumption demand of each node in the granary. Long-term contact with food will inevitably lead to sensor failure and other phenomena

Therefore, there are defects in information transmission that information transmission is unreliable and interference is not easy to eliminate

Regardless of the wired signal transmission and wireless signal transmission methods, the wiring distance is too long, resulting in unstable voltage and signal of the power supply

The number of measuring points in the granary depends on the number of sensors deployed. Considering cost, space and other reasons, the number of measuring points is limited, and it is impossible to fully detect the situation inside the granary, especially the detection of dangerous points in the grain situation, resulting in misunderstanding of the grain situation. judgment and misregulation, resulting in serious losses

Second, burying grain sensors, power supply and signal lines in the granary will affect the mechanized grain entry and exit operations, increase labor input, and reduce operational efficiency

[0003] These defects are also the most troublesome problems for granary managers in grain monitoring
