[0002] In the tobacco planting industry, field management during the growth process of tobacco plants is a key factor that determines the yield and quality of tobacco leaves. Among them, mulching and hilling are two core agronomic operations that have a direct impact on the root development, stress resistance, and ultimate economic benefits of tobacco plants.

[0003] Traditional mulching and soil covering operations rely heavily on manual labor, requiring the use of tools such as hoes and shovels. This not only involves extremely high labor intensity and costs, but also the possibility of damaging the mulch film due to improper force control during manual operation. This can affect the film's heat preservation and moisture retention effects, thereby reducing the stability of the tobacco plant's growing environment. Utility Model Content

[0004] The purpose of this utility model is to provide a tobacco film expansion and soil cultivation device, which solves the problem mentioned in the background art that traditional film expansion and soil cultivation operations are highly dependent on manual labor, requiring the use of tools such as hoes and shovels. This not only results in extremely high labor intensity and labor costs, but also the possibility of damaging the film due to improper force control during manual operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tobacco film expansion and soil cultivation device, comprising a box body, an electric push rod fixedly connected to the bottom of the protruding part at the top of the box body, the telescopic end of the electric push rod facing downward and fixedly connected to a lifting pipe, an adsorption block fixedly connected to the bottom end of the lifting pipe, a negative pressure groove opened on the inner side of the box body, the negative pressure groove and the lifting pipe being connected by a flexible hose, and a fan installed at the opening of the negative pressure groove.

[0006] In this technical solution, driven by the electric actuator, the lifting pipe and the adsorption block come into contact with the mulch film, thereby adsorbing the mulch film and raising it under the drive of the electric actuator, so that the mulch film is away from the tobacco plant stems, forming a ventilated space. At the same time, compared with manual operation, it not only effectively avoids the risk of mulch film damage, but also significantly improves the work efficiency of mulch film expansion operation, saving tobacco growers a lot of time and labor costs.

[0007] Preferably, the top of the box is provided with a soil-holding trough, and the side wall of the box below the soil-holding trough is provided with a side groove, and two No. 1 motors are fixedly connected to the inner side wall of the side groove.

[0008] Preferably, the side wall of the housing is provided with an adjustment groove, the opening of the adjustment groove faces the lifting tube, and a two-way lead screw is rotatably connected between the inner side walls of the adjustment groove. Two adjustment blocks are threaded through and connected to the surface of the two-way lead screw. A support frame is fixedly connected to the outer end of the adjustment block, and a push plate is fixedly connected to the side wall of the support frame.

[0009] Preferably, a discharge pipe is fixedly connected between the support frame and the soil-holding trough, the upper end of the discharge pipe is connected to the soil-holding trough, and the lower end of the discharge pipe is connected to the groove at the bottom of the support frame.

[0010] Preferably, the tail end of the drive shaft of the No. 1 motor is connected to the spiral guide rod located at the bottom of the soil trough, and one end of the spiral guide rod is located at the connection between the discharge pipe and the soil trough.

[0011] Preferably, a second motor is fixedly connected to the outer wall of the housing corresponding to the horizontal height of the bidirectional lead screw, and the tail end of the drive shaft of the second motor is connected to one end of the bidirectional lead screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a negative pressure groove and performing ventilation, allows the lifting pipe and adsorption block to contact the mulch film under the drive of the electric actuator, thereby adsorbing the mulch film and raising it under the drive of the electric actuator, keeping the mulch film away from the tobacco plant stems and forming a ventilated space. At the same time, compared with manual operation, it not only effectively avoids the risk of mulch film damage, but also significantly improves the work efficiency of mulch film expansion, saving tobacco growers a lot of time and labor costs.

[0014] 2. In use, the two support frames with push plates are inserted under the mulch film. While the lifting pipe and adsorption block adsorb the mulch film and pull it up, the spiral guide rod rotates under the drive of motor No. 1, guiding the soil prepared in advance in the soil-holding trough downwards until it falls out from the bottom of the support frame. Then the support frame moves laterally along the bidirectional screw, pushing the soil towards the center and piling it up to cover the perimeter of the tobacco crop, realizing the soil-building operation and optimizing the growth environment of the tobacco crop.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0021] A tobacco film spreading and soil cultivation device, see [link to documentation]. Figures 1 to 3 The system includes a housing 1, with a soil-holding trough 5 at its top. Fine soil for backfilling is prepared in the trough 5 and reduces the risk of clogging. A side groove 6 is located on the side wall of the housing 1 below the soil-holding trough 5. This side groove 6 facilitates the disassembly and maintenance of motor 701 and can also hold miscellaneous items. A negative pressure groove 303 is located inside the housing 1, connected to the lifting pipe 3 via a flexible hose 302. A fan 4 is installed at the opening of the negative pressure groove 303. An electric actuator 2 is fixedly connected to the bottom of the protruding part at the top of the housing 1, with the telescopic end of the electric actuator 2 pointing downwards and connected to the lifting pipe. 3. Fixed connection: The bottom end of the lifting pipe 3 is fixedly connected to an adsorption block 301. The edge of the adsorption block 301 is provided with a rubber ring to increase the sealing effect. When expanding the film, the box 1 is pushed to a suitable position, and then the electric push rod 2 is started, moving the adsorption block 301 downward and contacting the film. At this time, the fan 4 is started to draw air outward, thereby driving the airflow in the lifting pipe 3, the hose 302 and the negative pressure groove 303 to move, thereby sucking up the film. Then the electric push rod 2 is shortened, which can drive the film to rise, keeping the film away from the tobacco plant stems and forming a ventilated space. At the same time, compared with manual operation, it effectively avoids damage to the film and improves work efficiency.

[0022] Specifically, such as Figure 3 As shown, two No. 1 motors 701 are fixedly connected to the inner wall of the side trough 6. The tail end of the drive shaft of the No. 1 motor 701 is connected to the spiral guide rod 7 located at the bottom of the soil holding trough 5. One end of the spiral guide rod 7 is located at the connection between the discharge pipe 8 and the soil holding trough 5. When the No. 1 motor 701 is started, it drives the spiral guide rod 7 to rotate. During the rotation, the soil in the soil holding trough 5 can be guided into the discharge pipe 8, so that the soil falls down along the discharge pipe 8. The inner wall of the discharge pipe 8 is very smooth. If the soil is difficult to discharge, the discharge pipe 8 can be manually shaken to speed up the discharge operation. The discharged soil is piled up on both sides of the tobacco crop for easy use in subsequent soil covering.

[0023] Furthermore, such as Figure 1 and Figure 3 As shown, the side wall of the box 1 is provided with an adjustment groove 9. The opening of the adjustment groove 9 faces the lifting pipe 3. A double-acting screw 10 is rotatably connected between the inner side walls of the adjustment groove 9. A second motor 11 is fixedly connected to the outer side wall of the box 1 corresponding to the horizontal height of the double-acting screw 10. The tail end of the drive shaft of the second motor 11 is connected to one end of the double-acting screw 10. Two adjustment blocks 12 are threaded through and connected to the surface of the double-acting screw 10. A support frame 13 is fixedly connected to the outer end of the adjustment block 12. A push plate 14 is fixedly connected to the side wall of the support frame 13. Before adsorbing and lifting the mulch film, the two support frames 13 and the push plate 14 can be inserted under the mulch film. After the soil is added, the second motor 11 starts and drives the double-acting screw 10 to rotate. The two adjustment blocks 12 move relative to each other with their respective support frames 13. During the movement, the push plate 14 pushes the soil towards the center, thereby accumulating and covering the perimeter of the tobacco crop to realize the soil covering operation and optimize the growth environment of the tobacco crop.

[0024] It is worth noting that, such as Figure 1 and Figure 3 As shown, a discharge pipe 8 is fixedly connected between the support frame 13 and the soil trough 5. The upper end of the discharge pipe 8 is connected to the soil trough 5, and the lower end of the discharge pipe 8 is connected to the groove at the bottom of the support frame 13. The soil trough 5 is prepared with soil in advance for discharge, and the discharge pipe 8 is reserved with sufficient length to facilitate its bottom end to move laterally with the support frame 13.

[0025] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
