Description

Sugarcane ridge breaking stubble cutting machine with stubble cutting cutterhead capable of imitating terrain floating

Technical Field

The utility model relates to an agricultural machine for managing sugarcane perennial roots, in particular to a sugarcane ridge-breaking stubble-leveling machine with stubble-leveling cutterhead capable of floating in a terrain-like manner, and belongs to the technical field of agricultural mechanical equipment.

Background

The sugarcane perennial root refers to a sugarcane stump remained in a sugarcane field after the last year of sugarcane harvest, and can sprout again to soil and grow into sugarcane plants in the next year after proper agricultural management. The perennial root of the sugarcane can be generally used for 2-3 years and can be as long as 4-5 years, so that the sugarcane grown from the perennial root of the sugarcane accounts for more than 2/3 of the planting area of the sugarcane. However, after the sugarcane is harvested, especially manually, the perennial root of the sugarcane remained in the sugarcane field is always higher than the ground, if the stubble cutting, ridge breaking and root loosening, base fertilizer application, soil covering film covering and other treatments are not performed, the sugarcane stubble on the ground can rapidly germinate and grow at a high position, the root is not well covered with soil and nourished with fertilizer, and the sugarcane seedlings can die or can not thrive in the later stage due to insufficient nutrients in the growth process, so that the yield of the sugarcane is seriously affected. Therefore, after sugarcane harvest, agricultural management of sugarcane perennial roots is required in time.

The method is characterized in that the sugarcane is planted in the hilly and hilly fields in the south of China, the sugarcane field is mostly hilly and sloping fields, the existing sugarcane perennial stubble leveling equipment on the market is generally hung and driven by a tractor, the cutting depth of the stubble leveling device is generally controlled by hydraulic lifting adjustment and depth limiting wheels, the depth limiting wheels are firstly lifted to a high enough position, then the stubble leveling cutter disc is adjusted to a preset cutting depth by the hydraulic lifting device of the tractor in an operation state according to the requirement, at the moment, the operation is stopped, the cutting cutter tip is kept at the preset depth position for entering soil, and the depth limiting wheels are fixed after being lowered to be contacted with the ground, so that stubble leveling operation with set depth is realized. The stubble cutting depth control mode cannot be adjusted in a self-adaptive mode according to fluctuation of terrains, only manual adjustment can be adopted, the phenomenon that sugarcane perennial roots are damaged due to too deep penetration of a cutter head into soil can occur when the hillside terrains work, and the phenomenon that the stubble cutting depth is insufficient to cause the sugarcane to remain too long can occur when the hillside terrains work. Once the depth limiting wheel is adjusted and fixed, the cutter disc can be limited at a certain cutting depth, and the depth limiting wheel has a good depth limiting effect on a flat sugarcane field, but does not have a constant soil-entering cutting depth effect on a fluctuation sugarcane field. Therefore, the stubble cutting cutterhead of the existing sugarcane perennial root stubble cutting equipment cannot well adapt to the stubble cutting operation requirements of the sugarcane with fluctuation and change in the cutting depth. In addition, the existing stubble cutting cutterhead is driven to rotate by adopting a hydraulic motor, a corresponding hydraulic control system is needed to be provided for the stubble cutting cutterhead, the structure is complex, and the maintenance is not convenient enough.

Therefore, the stubble cutter head 10 of the sugarcane perennial root stubble cutter head can effectively solve the problem that the stubble cutter head 10 of the existing sugarcane perennial root stubble cutter can not adaptively adjust the cutting depth well when working on uphill and downhill terrains by virtue of the design of the stubble cutter head capable of imitating the terrain float.

The above-described drawings illustrate only typical embodiments of the utility model and are therefore not to be considered limiting of its scope, for the utility model may admit to other equally effective alternatives and modifications, without departing from the spirit and principles of the utility model.
