Embodiment Construction

[0030] The electronic control device consists of a controller, an electro-hydraulic proportional reversing valve, a display, a control panel, an angle sensor and a pin-type force sensor, and replaces the hydraulic control valve and the mechanical traction resistance signal and implement position in the traditional tractor hydraulic suspension system. Signal detection and transmission mechanism. The structure of the whole device is as figure 1 As shown, an angle sensor 5 is installed at the rotating shaft of the lifting arm 6 of the suspension device to detect the rotation angle of the lifting arm 6; the pin type traction force sensor 10 is installed in the hinged hole of the lower rod 9 and the tractor body to realize the connection between the lower rod and the tractor body. The articulated connection of the tractor body is used to detect the pulling force of the lower rod, that is, the traction force.

Abstract

The invention discloses a tractor operating depth resistance-position adjusting electric control device and method. The device is composed of an electric-hydraulic proportional reversing valve, a controller, a pin shaft type tractive force sensor, an angle sensor, a displayer, a control panel and the like. The displayer, the control panel and the controller are arranged on a cab of a tractor or a wheel fender of a right wheel. The controller is connected with the control panel, the displayer, a lower pulling rod pin shaft force sensor, the angle sensor and the electric-hydraulic proportional reversing valve through a signal cable. The pin shaft type tractive force sensor is arranged in a hinged hole between a lower pulling rod and a tractor body, and is used for detecting a tractive force signal which is exerted by the lower pulling rod on the tractor body. The angle sensor is connected with a tractor riser shell and a lifting arm rotary shaft outside the tractor, and is used for detecting the relative position between an agricultural implement and the tractor. The electric-hydraulic proportional reversing valve is arranged on the rear portion of the tractor, and can control the replacement of a lifting oil cylinder of a hydraulic hanging system according to the signal of the controller, and therefore the ascending and descending position of the agricultural implement is adjusted.

Description

technical field [0001] The invention relates to the field of adjusting and controlling the operating depth of agricultural tractor units, and relates to an electronic control device and method for adjusting the resistance-position of the operating depth of the tractor. Background technique [0002] The tractor-mounted unit is usually connected to agricultural implements through a hydraulic three-point hitch for field operations. The hydraulic suspension device pushes the hydraulic reversing slide valve to move through the mechanical sensing device, controls the hydraulic cylinder to lift or lower the agricultural implement, and adjusts the working depth of the agricultural implement unit. The field operation of tractor units should not only meet the requirements of different agronomy, such as the uniformity of operation depth, soil crushing capacity, soil fineness rate, surface smoothness, etc., but also strive to stabilize the load of tractor units, save fuel, improve produ...
