Description

Technical Field

[0001] The invention relates to the technical field of tobacco planting, in particular to a ground film laying device for tobacco planting. Background Art

[0002] Tobacco is an annual herbaceous plant of the genus Nicotiana in the Solanaceae family. It is pungent in taste and warm in nature. It enters the lungs and treats wind-cold-dampness arthralgia, stagnant qi and phlegm, mountain fog and miasma. It is a product for dispersing and dispersing. The water in the tobacco pipe can detoxify. Tobacco has the effects of killing crop pests, stomach poison, contact killing, and fumigation killing.

[0003] When planting tobacco, it is necessary to first make ridges on the land and then lay the ground film. The existing ground film laying device is very inconvenient when replacing the ground film roll, and the bolts on the rotating roller need to be disassembled and assembled, which is very time-consuming and inefficient. At the same time, when covering the edge of the ground film with soil, most of the existing devices insert the inclined wheel into the soil and turn the soil to the upper end of the ground film. This method is prone to leaking the cover and has a large resistance to the movement of the device.

[0038] Working principle of the mulch film laying device for tobacco planting:

[0039] Before covering the film, move the fixing rod 20 so that the end of the fixing rod 20 away from the sixth mounting rod 17 moves out of the inverted L-shaped opening 23, and then put the film roll on the fixing rod 20.

Then move the end of the fixing rod 20 away from the sixth mounting rod 17 into the inverted L-shaped opening 23, and then pull out the film so that the film passes through the lower end of the film pressing roller 9 and the lower end of the film pressing wheel 10 in turn, and then cover the end of the film with soil.

[0040] During film covering, the traction machine pulls the mounting frame 1 to move through the traction head 3 and the traction frame 2, the mounting frame 1 drives the first mounting rod 4 to move, the first mounting rod 4 drives the rotating wheel 6 and the spike row 5 to roll, and during the rolling process, the spike row 5 first inserts into the soil and then digs the soil.

[0041] Then the trenching inclined block 7 digs a groove for the loosened soil, and the excavated soil is transported upward under the action of the inclined surface of the trenching inclined block 7, and then the soil excavated by the trenching inclined block 7 and the surrounding soil are moved to the outside of the field ridge by the first bulldozer plate 8.

[0042] Then the film pressing roller 9 presses the ground film output by the fixing rod 20 onto the field ridge, and then the film pressing wheel 10 presses the edge of the ground film into the groove dug by the trenching bevel block 7, and then the second bulldozer 11 transports the soil moved by the first bulldozer 8 to cover the edge of the ground film, thereby completing the laying of the ground film.

[0043] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
