High-speed cutting, fetching and planting device for blanket rape seedlings

Abstract

The invention relates to a high-speed cutting, fetching and planting device for blanket rape seedlings. The high-speed cutting, fetching and planting device comprises a seedling box mover and a cutting and fetching mechanism, wherein the seedling box mover is provided with a seedling box, a seedling door is arranged at the lower part of the seedling box, the cutting and fetching mechanism comprises a box body, a seedling claw and a seedling pushing rod capable of moving along the seedling claw in a reciprocating manner, and the seedling claw comprises a pair of clamping sheets and a pair of elastic sheets; the seedling claw does cyclic motions at the variable speed along a seedling fetching and planting track of the corresponding seedling door, the seedling fetching and planting track comprises a seedling fetching section, a seedling pushing section and a return section; the elastic sheets protruding oppositely are respectively arranged on the opposite two sides of the two clamping sheets; the seedling box mover and the cutting and fetching mechanism are synchronously driven by a special shape gear set at the variable speed, so that the revolving speed of the box body of the cutting and fetching mechanism is relatively low when the seedling claw is on the seedling fetching section and the seedling pushing section, and the revolving speed of the box body of the cutting and fetching mechanism is relatively high when the seedling claw is on the return section. By using the device, a blanket rape seedling block is not easy to fall off, the seedling is less damaged when being cut and fetched, the planting quality is high, and the device is adaptive to a larger range of row spacing.

Description

technical field [0001] The invention relates to a high-speed cutting and planting device suitable for blanket seedlings of rapeseed, which belongs to the technical field of agricultural machinery. Background technique [0002] The perennial planting area of ​​rapeseed in my country is about 100 million mu, ranking first in the world in terms of area and total output. Rapeseed oil accounts for 57% of domestic edible vegetable oil, ranking first in domestic edible vegetable oil. The planting area of ​​rapeseed in the Yangtze River Basin accounts for 90% of the country's planting area, and is distributed in the upper, middle and lower reaches of the Yangtze River. 30-40% of them are restricted by crop rotation or climatic conditions. They do not have the conditions for direct sowing and must be transplanted by seedling cultivation. way of planting. In recent years, in some areas in the middle and lower reaches of the Yangtze River, rapeseed production has dropped by more than...

AI Technical Summary

Problems solved by technology

[0003] The existing chain clip or seedling tube transplanting machines at home and abroad, as well as the imported automatic dryland transplanting machines, cannot meet the high-efficiency transplanting of rapeseed, especially the high-efficiency mechanical transplanting of rapeseed under the condition of sticky and heavy soil in the paddy field. Needs, main problems: first, low operating efficiency and many auxiliary labors; second, poor adaptability to soil

[0005] The above two patents adopted the principle of transplanting blanket-shaped seedlings separately, which basically solved the technical problems of low transplanting efficiency of rapeseed and impossibility of transplanting in sticky soil. Developed, the existing rapeseed blanket seedlings have the characteristics of low moisture content and weak plate relay, so the planting mechanism of the rapeseed blanket seedling high-speed automatic transplanting machine is easy to scatter seedlings during high-speed cutting and picking. In addition, the canopy of rapeseed plants is relatively large, and the seedling claws are easy to knock down the transplanted seedlings when the planting distance is large, resulting in an increase in the number of fallen seedlings. smaller
