Problems solved by technology

However, due to the fixed spring stiffness and limited preload adjustment range, the self-excited vibratory subsoiler with the spring as the excitation source has a large difference in soil specific resistance, poor adaptability and intermittent failure when operating in different areas, resulting in plowing Deep stability cannot be guaranteed

Embodiment Construction

[0087] Such as figure 1 As shown, the present invention provides a self-excited vibration subsoiler, which includes a three-point suspension 7, a frame 6, ground wheels 2, a detection device 3, a touch screen 4, a hydraulic device 5, and a self-excited vibration subsoiler unit 1. The ground wheels 2 are installed on both sides of the frame 6, the three-point suspension 7 is installed in the middle of the front of the frame, and is used to connect with the tractor for farming. The detection device 3 is installed on the frame 6, and multiple self-excited vibrations are deep The loosening unit 1 and the hydraulic device 5 are installed on the frame 6. The self-excited vibration subsoiling unit 1 is used for loosening the soil, and the hydraulic unit 5 is used as the excitation source of the self-excited vibration subsoiling unit 1. The effect makes the submersible unit vibrate. The detection device 3 is used to detect the penetration depth of the self-excited vibration subsoilin...

Abstract

The invention discloses a self-induced vibration subsoiler and a deep tillage measuring and control method. The self-induced vibration subsoiler includes a rack, a detection device, a hydraulic device and a plurality of self-induced vibration subsoiler components, wherein the detection device is installed on the rack, and the self-induced vibration subsoiler components and the hydraulic device are arranged on the rack too; the self-induced vibration subsoiler components are used for loosening soil, and the hydraulic device serves as a vibration source and conducts vibration through the combined action with the soil; the detection device is used for detecting the embedded depth of the self-induced vibration subsoiler components, and controlling the hydraulic device according to the embedded depth, and therefore, the variation of deep tillage is controlled within a permissible range.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and relates to a self-excited vibration subsoiler and a tillage depth measurement and control method, which are mainly used in the field of soil subsoiler farming. Background technique [0002] Soil cultivation is an important part of agricultural production. Due to the long-term use of unreasonable farming methods such as shallow rotation and plowing, the quality of cultivated land in my country has been declining year by year, and crop production has been seriously reduced. Subsoiling soil preparation technology is to loosen the soil without turning the soil, which can effectively break the plow bottom layer and improve the soil aggregate structure. It has obvious advantages in soil improvement effect and has been vigorously promoted in recent years. Self-excited vibration subsoiling technology has obvious drag reduction effect. At present, self-excited vibration subsoilers use ...
