Multi-point layered grain detection rod

Abstract

The invention discloses a detecting rod for multi-point layered grain conditions. The detecting rod for the multi-point layered grain conditions includes a hollow insert attracting pipe and an insertdrawing pipe, wherein insert attracting holes are formed in the pipe wall of the insert attracting pipe. The detecting rod for the multi-point layered grain conditions further includes an upper folding pipe, a traction block, an insert collecting machine and a lower folding pipe, wherein the upper folding pipe, the traction block, the insert collecting machine and the lower folding pipe are located in the insert attracting pipe and arranged from top to bottom in sequence. The outer walls of the upper folding pipe and the lower folding pipe are attached to the inner wall of the insert attracting pipe. Gaps are reserved between the lower end surface of the traction block and the upper end surface of the insert collecting machine. The traction block and the insert collecting machine are correspondingly connected with the upper folding pipe and the lower folding pipe. A drive device is further arranged on the insert attracting pipe, and the drive device is used for driving the traction block and the insert collecting machine and slides in the axial direction of the insert attracting pipe in a single degree of freedom mode. The detecting rod for the multi-point layered grain conditionscan not only detect a fixed point of a space region in a granary, but also can detect the grain conditions at different depths of a grain bulk at the fixed point.

Description

technical field [0001] The invention relates to a detection device for detecting grain conditions, in particular to a multi-point layered grain condition detection device. Background technique [0002] At present, in the process of grain storage, due to the biological activity of grain, once there is a difference in storage conditions and grain quality, it will often cause heat generation, mildew, and pest breeding in the grain, which will lead to a serious decline in the quality of the stored grain. and many other issues. In order to maintain the stability of grain quality during the storage process, reduce the loss of stored grain, and ensure the long-term safe storage of grain, a special grain detection device is required to detect various parameters such as temperature, humidity, insect damage, and gas type and content of the grain depot. . [0003] Due to the huge warehouse capacity and numerous warehouses, in order to ensure grain quality and avoid local mold and ins...

Problems solved by technology

[0003] Due to the huge warehouse capacity and numerous warehouses, in order to ensure the quality of grain and avoid local mold and insect damage, it is necessary to detect at fixed points in the grain warehouse. Although the existing grain detection rod can detect the number of pests in the local area and the temperature in the grain pile, etc. , but it cannot detect abnormal grain conditions such as the number of pests at different depths of the grain pile at the same position, the temperature in the grain pile, etc., nor can it accurately locate the specific position of the abnormal grain situation in the vertical direction, and cannot meet the emergency treatment of abnormal grain conditions actual needs of the job

[0004] Secondly, the fixed-point detection in the grain depot has dozens or even hundreds of detection points, requiring the use of a large number of detection sensors of the same type. The detection system is expensive and the signal lines are complicated, making maintenance difficult.

If additional detection sensors are installed at different depths at the same point, it will exacerbate the high cost of the detection system, complicated signal lines and difficult maintenance
