Detailed Description

The following detailed description of the inventive embodiments is provided in connection with the accompanying drawings. A self-excited vibration subsoiler with controllable amplitude and vibration frequency comprises a frame type frame assembly 1, a support 7 is fixedly arranged on a front cross beam 18 of the frame type frame assembly 1, a loading adjusting bolt 6 is rotatably inserted on the upper side part of the support 7, a support sleeve 5 is sleeved on the outer part of the loading adjusting bolt 6, the support sleeve 5 is fixedly connected with the support 7, a front shaft 9 is fixedly matched on the lower side part of the support 7, a subsoiler seat 2 is rotatably and hingedly arranged on the rear side part of the support 7, an internal thread sleeve 4 is fixedly arranged on the front end part of the upper side of the subsoiler seat 2, the internal thread sleeve 4 is in threaded connection with the loading adjusting bolt 6, a loading pressure spring 3 is sleeved on the outer parts of the support sleeve 5 and the internal thread sleeve 4, the front end and the rear end of the loading pressure spring 3 are respectively in contact fit with the upper side parts of the support 7 and the subsoiler seat 2, a rear shaft 10 is fixedly arranged on the front end part, an auxiliary pressure spring 8 is sleeved on the outer portions of a front shaft 9 and a rear shaft 10, the front end and the rear end of the auxiliary pressure spring 8 are respectively in contact fit with the lower side portions of a support 7 and a subsoiler seat 2, a subsoiler assembly 11 is fixedly installed on the lower portion of the rear side of the subsoiler seat 2, an air spring 12 is hinged to a rear cross beam 17 of the frame type frame assembly 1, the front end of the air spring 12 is hinged to the subsoiler seat 2 located in the front of the air spring, and the air spring 12 is communicated with an air compressor 16 through an electric proportional valve 13, an air filter 14 and an air storage tank 15.

During operation, the subsoiler moves forward, and under the action of resistance changed by subsoiling soil, the subsoiler assembly 11 realizes reciprocating swing motion around a hinged point with the support 7 through the subsoiler seat 2, so that vibrating type subsoiling and soil crushing operation of the subsoiler assembly 11 on the subsoiled soil is completed. When the resistance of the subsoiling soil is large, the loading adjusting bolt 6 is rotated to enable the subsoiler seat 2 to pressurize the loading pressure spring 3 through the internal thread sleeve 4, and the amplitude and the vibration frequency of the subsoiler assembly 11 are effectively controlled within an effective and reasonable range. When the extrusion force of the loading pressure spring 3 reaches a reasonable limit position and cannot adapt to the resistance of deep scarification soil, the air compressor 16, the air storage tank 15, the air filter 14 and the electric proportional valve 13 are utilized to boost the air spring 12, meanwhile, the pressurizing adjusting bolt 6 is rotated reversely to increase the distance between the upper ends of the deep scarification shovel 2 and the support 7, the deep scarification shovel assembly 11 is pushed to rotate, the deep scarification shovel seat 2 is driven to relax the extrusion force of the loading pressure spring 3, at the moment, the loading pressure spring 3 has a telescopic space, the extrusion force of the loading pressure spring 3 and the thrust of the air spring 12 act on the deep scarification shovel assembly 11 together, the operation requirement of large soil resistance is met, and the reasonable regulation and control of the amplitude and the vibration frequency of the deep scarification shovel assembly 11 are completed.
