Double-row holing device for tobacco field

Abstract

The invention discloses a double-row holing device for a tobacco field, and relates to the technical field of agricultural mechanical equipment. The double-row holing device comprises a traction rack,a double-row holing rack, a driving device and holing devices, wherein the traction rack is connected with a traction device; the front end of the double-row holing rack is fixedly connected with thetraction rack, and the driving device is mounted on the double-row holing rack and used for driving the holing devices to perform holing; the driving device comprises a land wheel and a driving shaft; the land wheel is rotationally mounted on the double-row holing rack through a land wheel shaft; a driving chain wheel is mounted on the land wheel shaft, a driven chain wheel is arranged on the driving shaft, and the driving chain wheel is connected with the driven chain wheel through a driving chain; and two ends of the driving shaft are rotationally mounted on the double-row holing rack, andeach of two ends of the driving shaft is connected with a holing device. Two rows of pond holes can be formed at the same time in one stroke, so that the operation efficiency is improved, the field entry frequency of agricultural implements is reduced, and ridges are better protected.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a double-row opening device for tobacco fields. Background technique [0002] The scale of my country's tobacco industry is very large, and tobacco has been planted and promoted on a large scale in my country. At present, tobacco planting, especially Yunnan Province, the largest tobacco planting province, promotes the transplanting of small seedlings under plastic film in the process of transplanting tobacco seedlings. In the pre-drilled pond on Longshang. Requirements for opening ponds: the diameter of ponds is about 30cm, the depth is about 20cm, the distance between holes is about 60cm, and the row spacing is 120cm. After planting, the seedlings are about 15mm above the ground, and then water, fertilize and cover with film after planting. [0003] At present, most of the hole-opening machines used by tobacco farmers are portable and backpack-typ...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the hole-opening machines used by tobacco farmers are portable and backpack-type, which is labor-intensive and low-efficiency. Manual positioning and hole opening, the hole spacing is not accurate; the structure size of the auger is unreasonable, and the hole size is small. It cannot meet the production demand and the use effect is poor

There is also a single-row mechanical hole opening device, which can only open a single row of ponds in each stroke. The work efficiency is low, and it only works in a single link. Compound operations are required to further improve work efficiency and work quality.
