Shock resistance detection device for Beidou agricultural machinery positioning and monitoring terminal

Abstract

The invention discloses a shock resistance detection device for a Beidou agricultural machinery positioning and monitoring terminal, relates to the technical field of detection devices, and solves theproblems that an existing shock resistance detection device cannot well simulate the shock of a tractor, and the shock resistance detection accuracy of the positioning and monitoring terminal on thetractor is not high. The device comprises a longitudinal test rod, wherein the longitudinal test rod is fixedly connected to the top surface of the transverse test block. According to the device, thetest mounting plate can move transversely or longitudinally under the limiting action of the transverse test block and the longitudinal test rod; the shock of the tractor in use can be simulated underthe reset action of a test spring a and a test spring b, the vibration frequency is low, the vibration amplitude is large, the vibration state of the tractor in use can be truly simulated, the influence of vibration on the detection controller at the top of the test mounting plate is tested, and the accuracy is high.

Description

technical field [0001] The invention belongs to the technical field of detection devices, and more specifically relates to an anti-seismic detection device for a Beidou agricultural machinery positioning monitoring terminal. Background technique [0002] Agricultural machinery refers to all kinds of mechanical equipment used in agricultural production, such as large and small tractors, land leveling machinery and other equipment. With the development of the times, before the agricultural machinery is sold and used, it is necessary to install a positioning monitoring terminal on the agricultural machinery to achieve real-time monitoring of the working status of the agricultural machinery. It will be accompanied by vibration during use, so the positioning monitoring terminal needs to pass the shock resistance test before it can be installed on the agricultural machinery. [0003] At present, the main agricultural machinery and equipment used in rural areas are tractors, espec...

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides a shock resistance detection device for Beidou agricultural machinery positioning monitoring terminal to solve the problem that the existing shock resistance detection devices generally use a motor to directly drive the test board to vibrate, and its vibration frequency is high and the vibration amplitude is high. It is small and cannot be adjusted. When testing the shock resistance of the positioning and monitoring terminal through the existing shock resistance detection device, the engines of agricultural machinery such as tractors use fewer cylinders, and most of them are single-cylinder or double-cylinder designs. The vibration amplitude during use is relatively large, and the vibration frequency is slow, which leads to the fact that the existing anti-seismic detection device cannot simulate the vibration of tractor, an agricultural machinery equipment, so that the positioning monitoring terminal installed on the tractor cannot The accuracy of earthquake resistance detection is not high, and the practicability is poor
