Problems solved by technology

However, the disadvantage of this method of measurement is that the measurement accuracy and sensitivity depend entirely on the sensor, so the static performance of the sensor must be calibrated; in addition, when the multi-component force sensor is measured, mutual interference is inevitable, if the measurement If the value is not corrected, there will be a huge measurement error in a certain direction; after obtaining the component forces in six directions, it is necessary to simplify the forces in each direction; therefore, this method has a large workload and is easy to produce error

Embodiment Construction

[0015] When installing the isolation box, weld the shell sleeve 2 to the plow surface of the plow, open a hole at the welding place of the plow surface that is as large as the diameter of the support bottom cover 1, and put the support bottom cover 1 into the shell sleeve 2 Inside, the left part of the shell sleeve 2 is designed with a groove, which can make the supporting bottom cover stuck in the welding place between the plow surface and the sleeve 2, and play the role of supporting and protecting the sensor.

[0016] Put the pressure sensing surface of the pressure sensor into the isolation box towards the force-bearing direction of the plowshare surface.

[0017] Tighten the gland 4 to play the role of supporting and protecting the sensor.

[0018] The gland 4 and the sleeve shell 2 are threaded. In order to make the measurement of the plow surface pressure more accurate by the sensor, the gland can be screwed to control the position of the sensor in the space inside the ...

Abstract

The invention relates to a turnplow surface pressure sensor isolation box device. The device comprises a supporting bottom cover, a shell sleeve, a sensor position space and a gland; the left side part of the shell sleeve is matched and connected with the supporting bottom cover; the right side part of the shell sleeve is matched and connected with the gland; the supporting bottom cover and the shell sleeve are matched and connected with each other through a flange and a groove; the gland is connected with the shell sleeve in a screw-thread fit manner; a small hole is formed in the center of the gland and is used for leading out the lead of a pressure sensor, so that the lead of the pressure sensor can be connected with a data acquisition system; and the four parts are matched with one another so as to protect and support the pressure sensor, so that the distribution and magnitude of a load borne by a plow body in a working process are measured, and the stress characteristic rule of the plow body in the working process can be found out.

Description

technical field [0001] The invention relates to a plowshare surface pressure sensor isolation box device of a plowshare, which belongs to the field of farming machinery pressure measurement. Background technique [0002] The conventional plow is a common tillage tool widely used in agricultural operations and production. The plow body is an important working part of the conventional plow. Grass; the working surface of the plow body is a complex curved surface. Since the plowshare works in the soil, the surface of the plowshare is extremely easy to be damaged. Therefore, measure the load distribution and magnitude of the plow body during the working process to find out the force characteristics of the plow body during the working process It is an important method to study the dynamic performance of the conventional plow; it is of great significance for optimizing the performance of the conventional plow, rationally configuring the unit, and reducing energy consumption. [00...
