Problems solved by technology

At present, the torque measurement of the cutter shaft of the rotary tiller is generally inferred by measuring the output torque of the power machine to infer the torque of the cutter shaft, or using a collector ring to collect data. The results of these data collection methods have certain errors and cannot be analyzed in real time. The data is transmitted, and the collector ring is expensive, which brings some difficulties to the torque measurement

Abstract

The present invention discloses a rotary cultivator cutter shaft torque measurement apparatus, and belongs to the field of farm equipment. The apparatus comprises a sensor, an amplifier, a controller,a Bluetooth data sending module, a power source, a Bluetooth data receiving module and a computer. The sensor is stuck to a cutter shaft. The controller is fixed on the cutter shaft. A pin OUTPUT ofthe amplifier is connected to a pin AIN0 of the controller. The controller supplies power to the Bluetooth data sending module by using pins 3.3V, GND, RXD and TXD, and controls the Bluetooth data sending module to send data. The Bluetooth data receiving module is connected to the computer by using HC-USB-T, and a torque value is displayed on the computer in real time. The apparatus can conveniently and fast implement torque data transmission, to achieve an objective of wireless collection of a rotary cultivator cutter shaft torque.

Description

Technical field [0001] The invention relates to a rotary cultivator knife shaft torque measuring device, in particular to convert the analog signal measured by a strain gauge into a digital signal through a single chip microcomputer, and then display the rotary cultivator knife shaft torque on a computer through a Bluetooth data receiving module The device belongs to the field of agricultural equipment. Background technique [0002] Rotary tiller is a kind of tillage machine, which is widely used in agriculture, and the development of rotary tiller has been very mature. However, due to the promotion of protective tillage system and the extensive use of pesticides and fertilizers, the surface firmness of the soil has become very firm. Great changes. The breakage of the cutter shaft due to the change of resistance during the use of the rotary tiller still occurs. Therefore, it is necessary to measure the torque of the cutter shaft. The load spectrum of the torque measurement is use...
