Description

Vertical Rotary Ridger

technical field

The invention belongs to agricultural machinery, and mainly relates to land preparation operation implements.

Background technique

The rotary tiller ridging machine is one of the main operating models for dry field preparation in my country, especially in the northern region. Because it is suitable for the climatic conditions and agronomic requirements of the northern region and is conducive to increasing production, it is very popular among agricultural production users. However, all the existing rotary tillers adopt horizontal blade assembly structure. The big resistance of rotary tillage operation, serious wear of rotary tiller blade and short service life of cutter are very prominent problems. Rotary cultivators with this structure can only be used in conjunction with high-power tractors. Farmers in my country have a huge amount of low-power tractors that cannot use rotary tillers with this type of structure at all, resulting in the status quo that small-power tractors have fewer supporting tools and low utilization rates.

Contents of the invention

The object of the present invention is to aim at the problems and defects of the above-mentioned prior art, and to design and provide a vertical rotary tillage ridging machine with a new structure, which can greatly reduce the resistance of rotary tillage operations, reduce the wear of rotary tiller blades, and expand the capacity of rotary tillage. The purpose of improving the power matching range of implements and tractors and improving the utilization rate of low-power tractors.

The purpose of the present invention is achieved in this way: the frame is located on the rear side of the main gearbox and the sub-gearboxes are fixed symmetrically, the driving sprocket is fixedly fitted on the two ends of the power output shaft of the main gearbox, and the driven sprocket is fixedly installed On the shaft ends of the power input shafts of the two sub-gearboxes, the chain is sleeved on the driving sprocket and the driven sprocket; the lower end of the driving shaft of the sub-gearboxes is equipped with a cutter head horizontally, and the stubble removal rotary blade is fixed vertically. It is equipped on the lower end surface of the cutter head, and the cutter head and the stubble removal rotary tiller are located at the front side of the ridge share as a whole. The arrangement of the stubble removal rotary tiller on the lower end face of the cutter head is installed and fixed evenly at intervals at a size position of a radius of gyration , in a single-row knife structure, or installed and fixed at two positions with different gyration radii at intervals, and in a double-row knife structure, thus forming a vertical rotary tiller ridging machine.

The invention adopts the structure of vertically installing the stubble removal rotary tiller on the horizontally arranged cutter head. When the cutter head rotates horizontally, the implement moves forward with the traction power, so that the upright stubble removal rotary tiller moves horizontally on the upper layer of the land. It can be matched with small-power tractors or high-power tractors. It has the advantages of simple structure, small operation resistance, high production efficiency, long service life and low cost. It has the characteristics of low cost, good operation quality and wide supporting power range.

Detailed ways

Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. A vertical rotary tiller ridging machine includes a frame 7 and a ground wheel 1 fitted on the frame 7, a main gear box 5, and a ridge share 3, and the frame 7 is symmetrical on the rear side of the main gear box 5 The sub-gearbox 4 is fixed, the driving sprocket 13 is fixed on the two ends of the power output shaft 10 of the main gearbox 5, and the passive sprocket 6 is fixed on the shaft ends of the power input shaft 12 of the two sub-gearboxes 4. The chain 11 is sleeved on the driving sprocket 13 and the driven sprocket 6; the cutterhead 2 is installed horizontally on the lower end of the drive shaft 9 of the sub-gearbox 4, and the stubble rotary tiller 8 is fixed vertically on the lower end surface of the cutterhead 2 Above, its cutter head 2 and the stubble removal rotary tiller 8 are integrally positioned at the front side of the ridge share 3 . The configuration of the stubble removal rotary tiller 8 on the lower end surface of the cutter head 2 is installed and fixed evenly at intervals at a position with a radius of gyration R ₁ , in a single-row knife structure, or at two positions with different radii of gyration R ₁ and R ₂ It is installed and fixed evenly at intervals, showing a double-row knife structure.

During operation, the machine is integrated with the supporting power machinery. When the power machinery is pulling the machine to move forward, its output power passes through the main gear box 5, the power output shaft 10, the driving sprocket 13, the chain 11, the passive Sprocket 6, power input shaft 12, sub-gearbox 4, drive shaft 9, and cutter head 2 drive the stubble removal rotary tiller 8 to rotate in the horizontal direction, and move forward in a compound motion in a helical direction to remove stubble, The cutting operation of soil, when doing the soil cutting operation of helical line direction, the crushed soil after cutting is thrown on the ridging share 3 sidewalls of its rear side position to form a ridge shape immediately, and completes the ridging operation. The up and down adjustment of the ground wheel 1 on the frame 7 can realize the variation of the rotary tillage depth, and the up and down position adjustment of the ridge share 3 on the frame 7 can complete the adjustment and variation of the height of the ridge.
