Description

Technical Field

[0001] The utility model relates to the technical field related to tobacco planting mulch film punching, and in particular to a punching device for tobacco planting mulch film. Background Art

[0002] Tobacco is a plant of the genus Nicotiana in the Solanaceae family. It is an annual or limited perennial herb, covered with glandular hairs. Its roots are thick and strong, and are used as raw materials for the tobacco industry. The whole plant can also be used as a pesticide and insecticide. It can also be used as an anesthetic, diaphoretic, sedative, and emetic.

[0003] When planting tobacco, tobacco seedlings need to be planted in the fields. Before planting, one side of ground film needs to be laid on the ground. Ground film is a ground covering film, usually a transparent or black PE film, but also a green or silver film. It is used for ground covering to increase soil temperature, retain soil moisture, maintain soil structure, prevent pests from invading crops and diseases caused by certain microorganisms, etc., and promote plant growth. After punching holes on the surface of the ground film, the seedlings are planted in the holes. However, after the ground film is laid, it is necessary to manually punch holes on the surface of the ground film one by one, which is cumbersome. In addition, the distance between adjacent holes in the ground film is difficult to control, resulting in differences in the cultivation distance between the seedlings, which in turn affects the growth of the seedlings. At the same time, after completing the laying of a row of ground film, the staff needs to squat down and manually cut the ground film to lay the next row of tobacco planting land. The operation is inconvenient, time-consuming and labor-intensive. Utility Model Content

[0029] The following is a further explanation of the method and principle of the technical solution in this specific embodiment with reference to the accompanying drawings:

[0030] When laying mulch in a tobacco field, the staff first sends the mulch roll from the mulch entrance 3 into the space between the two first guide grooves 18, and then puts it into the space between the two second placement grooves 181 to complete the placement and limiting of the mulch roll. At the same time, the staff leads the mulch out of the mulch roll so that it passes through the bottom of the two guide rollers 20 and then buries its end in the soil to complete the fixation. Then the staff can place the burning charcoal through the charcoal inlet groove 44 into the charcoal placement tank 42. The high temperature of the charcoal makes the charcoal placement tank 42 in a high temperature state, and then the high temperature piercing of the mulch can be completed through the charcoal placement tank 42.

[0031] Then the staff starts the motor 28. The rotation of the power output shaft of the motor 28 drives the third transmission shaft 26 to rotate. The rotation of the third transmission shaft 26 drives the third bevel gear 27 concentric therewith to rotate. The rotation of the third bevel gear 27 drives the fourth bevel gear 29 meshing therewith to rotate. The rotation of the fourth bevel gear 29 drives the fourth transmission shaft 30 concentric therewith and the second pulley 31 to rotate. The rotation of the second pulley 31 drives the first pulley 10 to rotate through the transmission belt 32. The rotation of the first pulley 10 drives the first transmission shaft 7 and the traveling wheel 8 to rotate, thereby driving the entire device to move.

[0032] The synchronous rotation of the third transmission shaft 26 drives the second bevel gear 25 concentric therewith to rotate, and the rotation of the second bevel gear 25 drives the first bevel gear 24 meshing therewith to rotate, and the rotation of the first bevel gear 24 drives the second transmission shaft 23 concentric therewith to rotate, and the rotation of the second transmission shaft 23 drives the transmission roller 33 to rotate, and the rotation of the transmission roller 33 causes the driving ring 37 to reciprocate up and down under the guidance of the shaft protrusion 38 through the end-to-end spiral groove 36 opened in the internal transmission cavity 35 thereof, and then drives the driving plate 40 to reciprocate up and down through the driving shaft 39, and then the driving plate 40 drives the charcoal fire placement tank 42 to reciprocate up and down through the placement rod 41, so that the high-temperature charcoal fire placement tank 42 can complete the uniform high-temperature hole-breaking treatment of the ground film;

[0033] Synchronously, when a row of ground film is laid, the staff can quickly press the lower pressure plate 14, and then drive the gate knife 16 to cut down quickly through the first driving rod 12 and the knife holder mounting plate 15, thereby completing the shearing of the ground film. The synchronized first spring 13 can assist the gate knife 16 to move up and reset after the ground film shearing is completed.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
