Dual-row reverse-vibration subsoiler

Abstract

The invention discloses a dual-row reverse-vibration subsoiler, belonging to the field of agricultural machinery. The dual-row reverse-vibration subsoiler comprises a transmission system, a vibration subsoiling device, a supporting and depth-limiting device, a suspension frame and a frame, wherein the transmission system is arranged at the upper front side of the frame and used for transmitting power to the vibration subsoiling device via a power output shaft of a tractor; the vibration subsoiling device is arranged below the frame; the supporting and depth-limiting device is arranged at two sides of the rear part of the frame; and the suspension frame is arranged in the front part of the frame and connected with a suspension device of the tractor. According to the vibration mechanism disclosed by the invention, a structure with eccentric wheels arranged symmetrically and a connecting rod is adopted, and subsoiling shovels in the front row and the rear row are driven by the same transverse shaft to realize reverse vibration; and the two rows of shovels alternatively act forward and backward to loosen soil. Compared with the vibrations of all subsoilers in the same direction, the dual-row reverse-vibration subsoiler can be used for reducing peak traction resistance and oil consumption of the tractor and reducing vibration transferred to the frame and the tractor, and is suitable for subsoiling, land preparation and medium cultivation of soil.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a double-row reverse vibration subsoiler. Background technique [0002] Rotary tillage and common plow tillage are the main farming methods for the main grain crops in my country. Rotary tillage all year round results in a plow layer depth of only 15-20cm, and the bottom layer of the plow becomes hard, which is not suitable for the growth of crop root systems, resulting in crop yield reduction; Although the plowing depth of the conventional plow can reach 25-30cm, large-scale deep plowing operations lead to serious soil moisture loss, increased wind erosion and water erosion, and greatly increase the power requirements of power machinery and operating fuel consumption. [0003] Subsoiling can loosen the lower soil without loosening the surface of the cultivated land in a large area, break the bottom layer of the plow, increase the precipitation infiltration rate, increase the...

Problems solved by technology

[0004] The current large and medium-sized vibratory subsoilers all have multiple subsoilers, and all the subsoilers swing in the same direction and move synchronously during operation; when all the subsoilers swing forward synchronously, the overall soil resistance borne by the subsoiler components is the sum of the respective resistances of all the subsoiling shovels. During this process, the tractor’s instantaneous traction resistance will also reach the maximum value; and when all the subsoiling shovels swing back synchronously, the overall soil resistance borne by the subsoiling components is Minimal (minimum force of shovel tip can even reach 0); this situation will lead to a large peak value of traction resistance and a large fluctuation range of traction resistance, and may cause an increase in operating fuel consumption

[0005] For a vibratory subsoiler with multiple subsoilers, the high-frequency synchronous vibration of all subsoilers in the same direction makes the frame bear a large reciprocating excitation force in the front and rear directions, and this effect is transmitted to the machine through the suspension device. Tractor, causing strong vibration of the tractor, which deteriorates the working environment of the operator
