Description

Technical Field

[0001] This utility model belongs to agricultural machinery, and mainly relates to a combined paddy field leveling machine consisting of a dual-axis corrugated harrow tillage machine and a scraper leveler that are automatically controlled by intelligent satellites. Background Technology

[0002] Currently, leveling operations in paddy fields are completed sequentially by single-function harrow-type tillage machines and single-function scraper-type leveling machines. This method suffers from technical problems such as long operation cycles, high operating costs, low efficiency, and high labor intensity. Furthermore, the existing scraper-type leveling machines often employ an arc-shaped blade structure similar to that used on bulldozers. When leveling paddy fields, this easily leads to soil accumulation, high operating resistance, and poor leveling quality, making them particularly unsuitable for leveling paddy field soil. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the prior art and, in light of the actual needs of current paddy field preparation operations, to develop an intelligent satellite paddy field leveling machine. Through a reasonable structural design, the machine integrates a harrowing machine and a scraper-type leveling machine into a single structure with front and rear hinges, and is equipped with a triangular prism-shaped box-type leveling scraper. This achieves the combined operation of paddy field preparation and leveling, shortens the operation cycle, improves operation efficiency, ensures operation quality, reduces operation resistance and costs, and reduces the occurrence of operation failures.

[0004] The basic design of this utility model is as follows: a longitudinal beam frame is hinged to the upper side of the rectangular frame of the dual-axis corrugated harrow tillage machine, which can swing up and down longitudinally. The rear end of the longitudinal beam frame is fixed to the frame of the scraper grader. The scraper grader is hinged to the dual-axis corrugated harrow tillage machine in a way that allows it to swing up and down, thus forming an intelligent satellite paddy field leveling machine.

[0005] This utility model uses a longitudinal beam frame to connect a scraper grader that can swing up and down to the rear part of a dual-shaft corrugated rake grader. A grader scraper with an overall triangular prism-shaped box structure is installed on the scraper grader, realizing a combined operation of paddy field leveling. It has the characteristics of novel, unique, simple and reasonable structure, short leveling operation cycle, high operation efficiency, good operation quality, low power consumption and low failure rate. It is especially suitable for and meets the requirements of paddy field leveling operation. Attached Figure Description

[0011] The following is a detailed description of the embodiments of this utility model with reference to the accompanying drawings. An intelligent satellite paddy field leveling machine includes a dual-axis corrugated harrow tiller 1 and a scraper-type leveler 2. A three-point suspension assembly 1-2 is installed on the front end of the rectangular frame 1-1 of the dual-axis corrugated harrow tiller 1. A leveling scraper 2-3 is vertically and reciprocatingly hinged to the lower part of the leveler frame 2-1 of the scraper-type leveler 2. A bidirectional hydraulic cylinder assembly 2-2 is rotatably hinged to the upper side of the leveler frame 2-1. The cylinder rod end of cylinder assembly 2-2 is hinged to the leveling scraper 2-3, and the automatic controller 4 is wirelessly connected to the bidirectional hydraulic cylinder assembly 2-2. A longitudinal beam 3 is hinged along the upper side of the rectangular frame 1-1 of the dual-axis corrugated rake grader 1, allowing it to swing up and down longitudinally. The rear end of the longitudinal beam 3 is fixed to the leveling frame 2-1 of the scraper grader 2, thus hinged the entire scraper grader 2 to the dual-axis corrugated rake grader 1, allowing it to swing up and down. The leveling scraper 2-3 of the scraper grader 2 has a triangular prism-shaped box structure.

[0012] When in use, the machine is connected to the rear of the tractor by the three-point suspension assembly 1-2. It moves forward under the traction of the tractor. Under the action of the resistance of the paddy field soil, the corrugated rake blades on the dual-shaft corrugated rake tillage machine 1 rotate passively. After completing the rake, cut, crush and turn over the paddy field soil and weeds, stubble and stems, the leveling scraper blades 2-3 of the scraper grader 2, which are triangular prism-shaped box structure, immediately carry out the leveling operation. The paddy field leveling operation is completed in one continuous operation. By utilizing the hinged connection between the longitudinal beam frame 3 and the rectangular frame 1-1 of the dual-axis corrugated rake tillage machine 1, the leveling scraper 2-3 on the scraper-type grader 2 can move up and down following the contours of the paddy field soil surface. Combined with the buoyancy of the triangular prism-shaped box-type leveling scraper 2-3, this ensures that the scraper 2-3 remains positioned both on the paddy field soil surface and within the water layer, guaranteeing operational effectiveness while preventing soil clogging. During operation, the automatic controller 4 receives GBS electrical signals and, based on the changes in the paddy field surface elevation, controls the extension and retraction of the bidirectional hydraulic cylinder assembly 2-2 to rotate the triangular prism-shaped box-type leveling scraper 2-3 on the grader frame 2-1, adapting to changes in the paddy field surface elevation and achieving intelligent operation.
