Description
Technical Field
[0001] The invention relates to agricultural machinery, in particular to a rotary tillage, sowing and furrowing integrated machine. Background Art
[0002] At present, the cultivation of dryland straw returning to the field mostly involves deep rotary tillage to bury the stubble in the first step, shallow rotary tillage to sow and fertilize in the second step, and digging field drainage ditches in the third step. The tractor goes into the field three times to roll and compact the soil, which will cause a certain degree of damage to the soil structure, increasing the cost and affecting the sowing progress. When the moisture in the field is high in rainy weather, the indentation depth of the two driving wheels of the tractor is deeper than the trench dug by the trencher, forming a phenomenon of three trenches in one wheel. The seeds deeply buried by the wheel pressure will rot. At present, the trenching depth of the inclined double-disc trencher on the market is 250mm, and the trench width is mostly around 320mm. The trenching area is too large, affecting the yield. The disadvantage of the rotary tiller with a trenching disc in the middle of the blade roller is that the trenching disc cannot be controlled. As long as there is operation, there will be trenches. The shapes of many farmlands are irregular, and the drainage ditches in the fields are messy after operation, which is defective. Summary of the invention

[0004] Furthermore, the cutter disc drive shaft can rotate in the opposite direction, and the shaft end of the reverse-rotating cutter roller can be extended out of the side plate. The shaft end of the cutter roller extending out of the side plate is the cutter disc drive shaft. The shaft end of the forward-rotating cutter roller can also be extended out of the side plate, and a gear can be installed on the shaft end extending out of the side plate to drive the cutter disc drive gear in the cutter disc drive box to make the cutter disc drive shaft rotate in the opposite direction. The cutter disc drive gear can also be set in a side transmission box for the forward-rotating cutter roller and the reverse-rotating cutter roller, and the cutter disc drive gear is driven by the gear in the side transmission box to make the cutter disc drive shaft rotate in the opposite direction.
[0005] Furthermore, a protrusion is arranged on the driving arm and is tangent to the longitudinal arm fixed on the inner cutter disc, so as to drive the inner cutter disc and the outer cutter disc to rotate.
[0006] Furthermore, the inner cutter disc can be vertically arranged and the outer cutter disc can be obliquely arranged. Its structure is that a pair of bevel gears are arranged in the shell, the inner cutter disc is vertically arranged on the shaft end of the active bevel gear located on the inner side of the hanging arm, and the outer cutter disc is obliquely arranged on the shaft end of the longitudinal bevel gear located on the outer side of the hanging arm, and the longitudinal bevel gear is smaller than the active bevel gear.
[0007] Furthermore, the inner cutter disc may be vertically arranged on the inner side of the hanging arm, and the outer cutter disc may be vertically arranged on the outer side of the hanging arm. The structure is that a cutter disc shaft is arranged in the shell, and the inner cutter disc is vertically installed on the end of the cutter disc shaft located on the inner side of the hanging arm, and the outer cutter disc is vertically installed on the end of the cutter disc shaft located on the outer side of the hanging arm.
[0008] Furthermore, trenching knives may be arranged on both sides of the inner knife disc, and the position where the trenching knives are installed may be widened to a width of 100-200 mm.
[0009] The advantages of the present invention are: 1. The driving arm is used to drive the furrowing cutter disc mounted on the outside of the side plate to rotate and perform furrowing, so that rotary tillage, sowing and furrowing can be carried out synchronously. The furrowing structure can be raised and lowered and clutched by controlling the extension and contraction of the oil cylinder to meet the needs of furrowing on demand, and the structure is simple. 2. It solves the problem that the furrowing structure arranged in the middle of the rotary tiller and the ordinary furrowing machine equipped with the tractor cannot furrow along the edge of the field. 3. It reduces the number of times the tractor rolls on the ground and the embarrassing phenomenon of three furrows in one round of land, and also solves the problem that the seeds between the furrows pressed into furrows in rotten fields will rot and not germinate. 4. Side furrowing is conducive to spreading soil, which can reduce the width of the furrowing structure and reduce the area occupied by the furrow by more than 20 square meters per mu. Calculated by area, the wheat yield per mu can be increased by more than 15 kilograms, and the operation time and cost are greatly saved. BRIEF DESCRIPTION OF THE DRAWINGS
