Linkage type closed door structure and grain moisture detector

Abstract

The invention belongs to the technical field of grain moisture detection, in particular to a linkage type closed door structure and grain moisture detector. The linkage type closed door structure andgrain moisture detector comprises a shell body, a motor No.1 and a controller, wherein the shell body is internally provided with rolling wheels by means of a rotating shaft, a feeding port is arranged above the shell body, a discharging port is arranged below the shell body, and a controller is fixedly mounted on the outer side of the shell body; the controller is used for controlling the automatic operation of the device; two of the rolling wheels are set; and the rotating shaft is driven by means of the motor No.1. The linkage type closed door structure and grain moisture detector further comprises a closed door module and a rolling module, wherein the closed door module is used for closing or opening the feeding port and the discharging port in a linked manner, and comprises a connecting rod, a proximity switch, a motor No.2, a rotating base, an upper sealing plate and a lower sealing plate. The linkage type closed door structure and grain moisture detector improves the precision of grain moisture detection through fully rolling the grain by means of the rolling module and the rolling wheels in cooperation, realizes the linkage between the upper sealing plate and the lower sealing plate by means of the closed door module, and enables the feeding port and the discharging port to be kept in a synchronized open or closed state.

Description

technical field [0001] The invention belongs to the technical field of grain moisture detection, and specifically relates to a linkage type closed door structure and a grain moisture detector. Background technique [0002] Grain moisture detection technology is generally divided into direct method and indirect method. The direct method is to directly remove the moisture in the grain by drying or chemical methods, and detect the absolute moisture content of the sample. The direct method of moisture detection has high detection accuracy and is suitable for laboratory detection. The disadvantage is that the detection time is relatively long, and fast and online monitoring cannot be realized, so it is difficult to meet the speed and continuous requirements of modern production. The indirect method is through the detection of physical quantities related to moisture, mainly including resistance moisture determination, nuclear magnetic resonance method, capacitive moisture determi...

Problems solved by technology

[0003] However, in the detection process, it is not taken into account that insufficient rolling of the grain may cause the moisture in the grain to not be fully squeezed out, resulting in inaccurate moisture detection. Based on this, the present invention proposes a linkage type closed door structure and grain moisture detection. The instrument, which cooperates with the closed door module and the rolling module to fully roll the grain, ensures that the moisture of the grain is fully rolled, and at the same time closes the door module to keep the feeding port and the feeding port in a state of opening or closing synchronously, thereby Improved accuracy of grain moisture detection
