General agricultural machinery performance detecting device

Abstract

The invention discloses a general agricultural machinery performance detecting device, and belongs to the field of agricultural machinery detecting equipment. The general agricultural machinery performance detecting device comprises a data acquiring instrument (1), and is characterized in that the data acquiring instrument (1) is mounted on a semitrailer, and can travel with the semitrailer; the semitrailer comprises wheels (2); the two wheels (2) are connected together through an axle (3); a box body for holding the data acquiring instrument (1) is supported and mounted on the axle (3); the front end of the box body is connected with a V-shaped connection frame (4); the V-shaped connection frame (4) is connected with the end head of a connection rod (5); a hanger connection piece (6) capable of being hung on agricultural machinery is arranged at the other end head of the connection rod (5). The agricultural machinery braking performance detecting instrument is simple and convenient to mount, and accurate in detection, and can be suitable for detecting various types of agricultural machinery.

Description

technical field [0001] The utility model relates to a general-purpose agricultural machinery performance detection device, which belongs to the field of agricultural machinery detection equipment, and specifically relates to an agricultural machinery braking performance detection equipment. Background technique [0002] There are many types of agricultural transport machinery, with large differences in shape and running speed. It has always been a difficult problem to detect the braking performance of these vehicles. [0003] At present, the method of detecting the braking distance of agricultural machinery is mainly to carry out the detection test during the running of the vehicle. There are two main detection instruments: one is a non-contact speed meter using a non-contact photoelectric sensor, and the other is a fifth-wheel meter. . Due to the large vibration of the agricultural machinery when it is running and idling, the non-contact photoelectric sensor still vibrates...

AI Technical Summary

Problems solved by technology

Due to the large vibration of the agricultural machinery when it is running and idling, the non-contact photoelectric sensor still vibrates with the vibration of the vehicle when the brake detection is completed, and it cannot judge the stopped state of the vehicle in time, which brings great errors to the measurement results.

The five-wheel instrument uses a contact fifth wheel sensor to connect with the vehicle, which is suitable for low-speed vehicle detection. However, because the fifth wheel sensor uses a special connection device, the connection with the vehicle under test is very complicated, and even the vehicle under test needs to be tested. Appropriate modification can ensure the connection between the fifth wheel sensor and the vehicle under test, which makes it very inconvenient when testing large quantities of agricultural machinery
