Description

Technical Field

[0001] This utility model belongs to agricultural machinery, and mainly relates to a combined tillage machine that performs rotary tillage and ridging operations. Background Technology

[0002] Ridge planting is a dryland farming technique adapted to cold regions. Due to its advantages such as wind protection, increased soil temperature, moisture retention, and reduced soil erosion, it has long been a widely used planting method in Heilongjiang and Jilin provinces of Northeast my country. To ensure and improve the yield and quality of crops planted the following year, and to provide a good seedbed environment and conditions, agronomical techniques require that autumn tillage, namely rotary tillage and ridging, be carried out immediately after the autumn harvest and before the ground freezes. However, existing autumn tillage equipment consists of separate rotary tillers and ridging machines. The process involves first using the rotary tiller to till the land, followed by ridging with the ridging machine. This long cycle makes it impossible to complete large-scale rotary tillage and ridging within the short time before the soil freezes after the autumn harvest. Therefore, shortening the autumn tillage time and increasing the area tilled is a crucial technical problem that must be solved. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the prior art and, in combination with the actual needs of current ridge-cultivation agronomic methods for mechanized land preparation, to develop and design a combined rotary tillage and ridging machine to improve the efficiency of ridge-cultivation operations, shorten land preparation time, and ensure the quality of operations.

[0004] The basic design of this utility model is as follows: furrow retaining moldboards are fixedly installed on the lower side of the rear crossbeam of the frame assembly from left to right at intervals. An arc-shaped high-strength moldboard tip is fixedly installed on the lower end of the furrow retaining moldboard. Ridging and retaining side plates are fixedly installed on the outer parts of the furrow retaining moldboards at the left and right ends of the rear crossbeam of the frame assembly. A ridge forming pressure plate is hinged and can swing up and down on the lower side of the rear crossbeam of the frame assembly between adjacent furrow retaining moldboards. The lower end of the contour control rod is hinged to the ridge forming pressure plate. The upper part of the contour control rod is telescopically inserted into the rear crossbeam of the frame assembly. A pressure spring is fitted on the contour control rod. The upper and lower ends of the pressure spring are respectively in compression contact with the rear crossbeam of the frame assembly and the ridge forming pressure plate for positioning. This constitutes a rotary tillage and ridge forming combined land preparation machine.

[0005] This utility model combines a rotary tiller with a ridging component that has excellent deep loosening and ridging functions, realizing a combined operation of rotary tillage and ridging. It features high operating efficiency, good operating quality, short operating cycle, and reduced operating costs, providing technical support for autumn land preparation in the ridge-growing areas of Northeast China, and providing high-quality seedbed conditions for spring sowing in the following year.

[0013] The following is a detailed description of the embodiments of this utility model with reference to the accompanying drawings. A combined rotary tillage and ridging tillage machine includes a frame assembly 1. A three-point suspension mechanism 3 is fixedly mounted on the front end of the frame assembly 1. A rotary tillage roller 2 is rotatably supported and mounted on the lower middle part of the frame assembly 1. Furrow retaining moldboards 5 are fixedly mounted from left to right at intervals on the lower side of the rear crossbeam of the frame assembly 1. An arc-shaped high-strength moldboard tip 4 is fixedly mounted on the lower end of the furrow retaining moldboard 5. At the two ends of the rear crossbeam of the frame assembly 1, on the outer parts of the furrow retaining moldboards 5 at the left and right ends, respectively, are fixedly mounted... The ridge-forming plate 6 is hinged to the lower side of the rear crossbeam of the frame assembly 1, located between the adjacent ridge-forming moldboards 5, and can swing up and down. The lower end of the contour control rod 8 is hinged to the ridge-forming plate 9, and the upper side of the contour control rod 8 is telescopically inserted into the rear crossbeam of the frame assembly 1. The pressure spring 7 is fitted onto the contour control rod 8, and the upper and lower ends of the pressure spring 7 are respectively in compression contact with the rear crossbeam of the frame assembly 1 and the ridge-forming plate 9 for positioning.

[0014] During operation, the machine is suspended and connected to the rear of the traction power machinery using the three-point suspension mechanism 3. It moves forward randomly, and the external power drives the rotary tiller roller 3 to rotate actively to first complete the rotary tillage and crushing of the soil. The crushed soil is then thrown to the area between the two ridge-building retaining side plates 6 on the rear side, located in front of the furrow retaining moldboard 5 and the ridge-forming pressure plate 9. At the same time, the arc-shaped high-strength moldboard tip 4 loosens and lifts the soil in the furrow area to supplement the amount of soil for ridge formation on both sides to meet the ridge formation requirements. Then, under the action of the contour control rod 8 and the pressure spring 7, the ridge-forming pressure plate 9 compresses and shapes the soil located between the adjacent furrow retaining moldboard 5 in a floating contour movement, completing the ridge-forming process.
