Description

Technical Field

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

[0002] When planting crops, mulch film is needed to cover them. After mulch film covering cultivation, the temperature and moisture conditions of the soil and near the ground can be improved, which can increase soil temperature, maintain soil moisture, improve soil properties, improve soil nutrient supply and fertilizer utilization, improve lighting conditions, reduce weeds and pests and diseases, etc. It can also keep warm and increase temperature, promote the decomposition and release of soil nutrients, and keep moisture, improve survival rate. After the mulch film is laid, it is necessary to punch planting holes through a mulch film puncher to facilitate plant planting. The existing publication number is CN 218302152 U. A mulch film puncher can adjust the distance between the adjustment rod and the punching teeth through a hole spacing adjustment mechanism, so that holes can be punched at a fixed distance according to different crops. There is no need to manually measure the distance between the planting holes and then punch the holes. Punching is convenient and fast, with higher efficiency, and the spacing between the planting holes is the same; however, the above-mentioned puncher needs to manually place and compare the punching positions during operation, which increases the operation steps and affects the efficiency and labor of punching.

The sliding rod 24 is slidably connected to the guide sleeve 26, so that during the rotation of the crankshaft 21, the sliding rod 24 connected to the connecting sleeve 22 is driven to move up and down under the limit of the guide sleeve 26, so that the cone head 25 punches holes in the ground film on the lower side.

[0026] In this embodiment: the moving mechanism 3 includes a rotating shaft 31 rotatably connected to the frame 11, and the two ends of the rotating shaft 31 pass through the frame 11 and are respectively fixed with adjustment components 35. A transmission component is arranged between the rotating shaft 31 and the crankshaft 21, and the transmission component includes an auxiliary sprocket 33 arranged on the crankshaft 21, and a driving sprocket 32 ​​is installed on the rotating shaft 31. The driving sprocket 32 ​​and the auxiliary sprocket 33 are sleeved with a transmission chain 34; the adjustment component 35 includes a hub 351 fixed to the rotating shaft 31, and the hub 351 is in an inner and outer double ring type.
