Test stand used for detection of special weeding cutter performance in peucedanum praeruptorum medicine filed

Abstract

The invention discloses a test stand used for detection of special weeding cutter performance in a peucedanum praeruptorum medicine filed. The test stand comprises a work platform and a data acquisition, processing and analyzing platform. Four depth wheels, a variable frequency motor, a right shaft coupling, a torque and rotation speed sensor, a left shaft coupling and a cutter are installed on the work platform, wherein the right shaft coupling, the torque and rotation speed sensor, the left shaft coupling and the cutter are successively connected with the variable frequency motor. The variable frequency motor and the torque and rotation speed sensor are fixed on the work platform via bolts separately. The data acquisition, acquiring and processing platform comprises a frequency converter, a relay switch, a data acquisition card, an NI-PXI platform, a laptop and a trolley. According to the invention, via the test stand, field tests can be carried out in the peucedanum praeruptorum medicine filed; torque and rotation speed of different kinds of special weeding cutters in the same working environment can be measured; and a LabView software is used for compiling the corresponding program and the interface so as to process and display the data.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, and more specifically relates to a test bench for performance testing of special weeding knives for pedicure fields. Background technique [0002] Peucedanum is a traditional Chinese medicinal material with high medicinal value, which is used for exogenous wind-heat, lung heat and phlegm stagnation, and asthma with excessive phlegm. Weeding in medicine field is an important link in the production of Peucedanum. At present, there is no special weeding tool for Peucedanum in the market. There are many kinds of common weeding knives with different performances, and their design does not match the agronomy and growth characteristics of Peucedanum planting. As a result, weeding in the Peucedanum medicinal fields still relies on manual weeding. This weeding method has the disadvantages of high labor intensity, high cost, and low efficiency, which seriously restricts the development of th...

Weeding in medicine field is an important link in the production of Peucedanum. At present, there is no special weeding tool for Peucedanum in the market. There are many kinds of common weeding knives with different performances, and their design does not match the agronomy and growth characteristics of Peucedanum planting. As a result, the weeding of the peucedanum medicine field still relies on manual weeding. This weeding method has the disadvantages of high labor intensity, high cost, and low efficiency, which seriously restricts the development of the peucedanum industry in our country.
