Farmland ditcher and controlling method thereof

Abstract

The invention relates to the field of agricultural machines, in particular to a farmland ditcher. The farmland ditcher comprises a rack, a ditching cutter head, a supporting device, a driving device and a controller. The ditching cutter head and the supporting device are respectively arranged on the rack, and the driving device is connected with a revolving shaft of the ditching cutter head. The controller controls the driving device to respectively drive the ditching cutter head to perform ditching work and drive the supporting device to perform lifting movement, and the driving device is an independent hydraulic system. According to the farmland ditcher, the driving device is utilized to drive the ditching cutter head to rotate and drive the supporting device to perform lifting movement so as to adjust the height of the rack, and therefore the depth adjustment of the ditching work is performed. The hydraulic driving type working principle is utilized, power of the ditching work is provided through the independent hydraulic system, automatic control of the rotating speed of the ditching cutter head and lifting of the supporting device of the farmland ditcher is performed with a controlling method of the farmland ditcher, real-time adjustment of the rotating speed of the ditcher cutter head and the depth of the ditching work is achieved, and work adaptability of the farmland ditcher to different soil conditions is improved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a farmland ditching machine and a control method thereof. Background technique [0002] Farmland irrigation canals and drainage ditches are important infrastructures of farmland in our country. At present, most of the farmland irrigation canals in our country are earth canals dug by hand or ordinary engineering excavation machinery. The ditches dug out are very irregular in shape and need to be trimmed manually, which affects the quality of irrigation canals and construction efficiency. There are few special ditching equipment for farmland canal construction in my country. Basically, plows are used for ditching or engineering excavation machinery. Utilize the working principle of rotary milling to carry out ditching operations. The rear power output shaft of the tractor outputs power to the gearbox through the universal joint drive shaft. and throwing soil to dig ditches. Th...

Problems solved by technology

[0003] The existing ditching equipment mainly has the following defects: the power consumption of the ditching equipment itself is relatively large during the ditching operation, the power consumption of the tractor is increased during the operation, the requirements for the matching tractor are very high, and the versatility is poor; mechanical transmission is used to provide The power and transmission ratio are single, and the rotation speed of the ditching cutter head cannot be adjusted, which reduces the adaptability of the existing ditching equipment to different soil and soil conditions during the operation process, and the application range of the ditching machine is limited; the ditching equipment adopts three-point suspension It is mounted on the three-point suspension frame at the back of the tractor, and the operating depth of the ditching equipment is manually adjusted by using the hydraulic lifting system of the tractor itself. As a result, the operating depth of the ditching equipment cannot be adjusted automatically in real time, and the ditching equipment needs to be repeated many times. The excavation of the trapezoidal cross-section canal was successfully completed
