Description

Technical Field

[0001] The utility model relates to the technical field of cabbage harvesting equipment, in particular to a single-row cabbage harvester. Background Art

[0002] Cabbage occupies an extremely critical position in food consumption due to its good economic and nutritional value. At the same time, due to the advantages of cabbage such as high unit yield, storage and transportation resistance, and long supply period, the harvested area and yield have been growing steadily year by year and generally maintained at a high level. Chinese cabbage planting is generally relatively scattered and small-scale, with low overall mechanization and industrialization levels. At present, cabbage harvesting operations still rely mainly on manual labor, which has problems such as low work efficiency, high labor intensity, high operating costs, and difficulty in controlling manual harvesting quality and operating efficiency. The cabbage harvesters and supporting technical devices in the existing technology have low efficiency and high damage rates, which greatly limit the efficiency and benefits of cabbage production. At the same time, the root cutting requirements during cabbage harvesting operations are high. During the operation of existing cabbage harvesters, there are problems such as inaccurate root cutting position, high mechanized operation damage rate, high failure rate and low automation level. Therefore, how to provide a cabbage harvester secondary precision root cutting device that can reduce the damage rate of mechanized harvesting operations and has high harvesting efficiency is a technical problem that needs to be solved urgently in this field.

The two chains engage and move to clamp the roots of the cabbage while achieving the first root cutting of the mud and roots at the roots. When the cabbage moves to the disc cutter with the special-shaped conveyor belt, the disc cutter adopts two upper and lower partially overlapping arrangements to ensure complete cutting of the main root of the root, thereby achieving two root cutting operations, avoiding the problems of poor root cutting effect and high machine failure rate caused by the traditional cabbage harvester due to the large amount of mud and sand at the roots, thereby improving the efficiency of the cabbage harvesting operation and reducing the workload of the operator.

[0031] A set of double-belt clamping conveying devices 7 are provided in parallel on the upper side of the cutting platform 6; the double-belt clamping conveying device 7 consists of two special-shaped conveyor belts 74, pulleys 73, a hydraulic motor 71, and a transmission box 72. The pulleys 73 at both ends of the two special-shaped conveyor belts 74 are arranged symmetrically and parallel to the axis, ensuring that the two special-shaped conveyor belts 74 can clamp the cabbage to keep it upright while transporting it obliquely upward to the primary conveying device 4; the hydraulic motor 71 is fixed on the upper side of the cutting platform 6, and the hydraulic motor 71 is connected to the pulley 73 through the transmission box 72. The special-shaped conveyor belt 74 has U-shaped hollow protrusions evenly spaced on the belt surface, and the hydraulic motor 71 drives the special-shaped conveyor belt 74 to rotate through the transmission box 72 and the pulley 73.

[0032] A set of parallel guide rods 8 are provided at the front end of the cutting platform frame 6. The rear ends of the guide rods 8 are fixedly connected to the bottom side of the cutting platform frame 6. The spacing between the two sets of guide rods 8 is equivalent to the spacing between the two special-shaped conveyor belts 74. The guide rods 8 are arranged parallel to the special-shaped conveyor belts 74. The front ends of the guide rods 8 are designed to be upturned to ensure that the front ends of the guide rods 8 are in a horizontal state during the operation of the cutting platform 1.

[0034] The chain buckle plates of the chain 92 are each provided with a sawtooth, which faces the outer ring of the chain. The meshing movement of the two chains can clamp the roots of the cabbage while achieving the first root cutting of the mud and root fibers at the roots. When the cabbage moves to the disc cutter 91 along the special-shaped conveyor belt 74, the disc cutter 91 adopts two upper and lower partially overlapping arrangements to ensure the complete cutting of the main root, thereby achieving two root cutting operations, avoiding the problems of poor root cutting effect and high machine failure rate caused by the traditional cabbage harvester due to the large amount of mud and sand at the roots, thereby improving the efficiency of the cabbage harvesting operation and reducing the workload of the operator.
