Vibration digging shovel for long-rhizome crops

Abstract

The invention relates to the technical field of agricultural machinery, in particular to a vibration digging shovel which is driven by a cam mechanism and suitable for harvesting long-rhizome crops. The vibration digging shovel comprises a frame and is characterized in that a vibration digging shovel body is hinged to the frame, a gearbox is mounted on the frame, the power of the gearbox is inputthrough a tractor gearbox power output shaft and then output through a power output crank shaft, the power output crank shaft transmits the power to a vibration screen swing rod and a chain transmission mechanism at the same time, the chain transmission mechanism transmits the power to the cam transmission mechanism, and the cam transmission mechanism transmits the power to the vibration digging shovel body to allow the vibration digging shovel body to move in a reciprocating manner. The vibration digging shovel has the advantages that the vibration digging shovel integrates multiple procedures such as vibration resistance reducing, vibration crushing, crop separation, soil loosening, soil screening and plowing; by the two-dimensional vibration with the advancing direction being 45 degreesand the travel being 10mm, the traction resistance of the vibration digging shovel is lowered effectively, and the operation depth and efficiency of the vibration digging shovel are increased.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a vibrating digging shovel driven by a cam mechanism and suitable for harvesting long root crops. Background technique [0002] The harvesting of long rhizome crops has always been a difficult problem in the field of agricultural machinery. The growth depth of the roots of such rhizomes is mostly below 20cm in the soil, and some can even reach about 50cm. This places extremely high demands on the mechanized harvesting of such crops. [0003] Chinese patent CN207443467U discloses a kind of excavator, and this patent is provided with fixed digging shovel at excavator front portion, utilizes this digging shovel to feed crops and soil into the vibrating screen of harvester rear portion during operation. The crops are separated from the soil, weeds, etc. by the shaking of the shaking sieve. Because the excavating shovel of this invention is a fixed structure, when the...

AI Technical Summary

Problems solved by technology

Because the excavating shovel of this invention has a fixed structure, when the operating depth of this harvester is deepened to 30-50 cm, the tractor traction resistance is very large, resulting in a decrease in operating efficiency, and even the expected operating depth cannot be reached.

In another disclosed Chinese patent CN207491531U, the excavating shovel is driven by an exciting oil cylinder. During operation, the excavating shovel generates vibrations in the front and rear directions to reduce the resistance of the soil to the advancement of the machine, but because this mechanism can only generate vibrations in the front and rear directions Reciprocating motion belongs to one-dimensional vibration, so the drag reduction effect is limited
