Description

Technical Field

[0001] This utility model relates to the field of flue-cured tobacco planting technology, specifically to a handheld film-tearing device for mulch film. Background Technology

[0002] Film removal is an important measure in flue-cured tobacco cultivation. On the one hand, it improves soil structure, facilitates cultivation and hilling, prevents soil compaction, and provides good soil conditions for tobacco plant growth. On the other hand, film removal increases root aeration, which is beneficial for water and nutrient absorption, prevents high-temperature burn and wilting, promotes plant growth and development, extends the growing season, and improves tobacco leaf quality. Currently, there are three commonly used film removal methods: partial removal, full removal, and complete removal. Partial removal refers to tearing a strip about 20 centimeters wide in the middle of the film (mulch film) between adjacent tobacco plants; full removal refers to tearing off all the film covering the top surface of the trapezoidal ridge, leaving only the film on the sides of the ridge; complete removal refers to completely removing the mulch film. Different varieties, when treated with different film removal methods, will improve the yield and quality of flue-cured tobacco to a certain extent, and these methods are widely used in major tobacco-growing areas. However, in current field production, farmers mainly rely on manual semi-tearing of the film, which has disadvantages such as inconsistent tear sizes, easy tearing of the film, and difficulty in recycling. This results in uneven distribution of water and nutrients in tobacco plants, film pollution of the soil, increased labor costs, and reduced production efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a handheld film-tearing device for mulch film. It mainly solves the technical problems that farmers currently rely on manual semi-tears of mulch film during flue-cured tobacco planting, which result in inconsistent tear sizes, easy tearing of the film, and difficulty in recycling.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A handheld film-tearing device for mulch film includes a main body, on which two opposing grippers are provided and a gripper opening and closing control mechanism connected to the two grippers for controlling the two grippers to move closer together to form a clamping state or to move away from each other to form an open state. The two grippers are provided with blades that are oppositely arranged for cutting the mulch film into long strips.

[0006] Furthermore, each of the two grippers has a clamping plate portion, which are arranged opposite to each other. When the gripper opening and closing control mechanism controls the two clamping plates to move closer to each other and close together, the clamping action of the two clamping plates will clamp the mulch film.

[0007] Furthermore, the cutting edge is formed at the bottom of the clamping plate.

[0008] Furthermore, the main body includes a cylinder, inside which a telescopic rod is fitted. A mounting seat is provided at one end of the cylinder, and two grippers slide on the mounting seat from left to right. The two grippers are connected to the telescopic rod through a traction member. The telescopic rod and the traction member work together to form a gripper opening and closing control mechanism that can control the movement of the two grippers by pulling the telescopic rod.

[0009] Furthermore, the mounting base has two gripper mounting parts for mounting the two grippers respectively. The gripper mounting part includes two oppositely arranged side plates and a guide slide rod connected between the two side plates. The grippers slide on the guide slide rod, and an elastic reset member is provided between the grippers and the side plates to automatically move the two grippers away from each other to form an open state.

[0010] Furthermore, the elastic reset component is a compression spring, with one end of the compression spring abutting against the inner side plate of the gripper mounting part, and the other end abutting against the gripper.

[0011] Furthermore, the traction component is a traction rope, which is movably attached to the hanging hole at the bottom of the telescopic rod. Both ends of the traction rope pass through the corresponding side plates and are fixedly connected to the two claws on the mounting base. The top of the telescopic rod extends upward relative to the cylinder, and a handle is provided at the top of the telescopic rod.

[0012] Furthermore, a flange is provided at the top of the telescopic rod, and a movable sleeve is screwed to the top of the cylinder, which is vertically opposite to the flange. By rotating the movable sleeve, the connection height of the movable sleeve relative to the cylinder is changed, so that the maximum opening between the two grippers can be adjusted by the abutting and limiting cooperation between the top of the movable sleeve and the flange.

[0013] Furthermore, the side plate of the gripper mounting part is equipped with a steering wheel to facilitate the pulling of the gripper by the traction rope.

[0014] Furthermore, several piston components adapted to the interior of the cylinder are installed on the telescopic rod.

[0015] The above technical solution has the following advantages or beneficial effects:

[0016] The handheld film-tearing device for mulch film described in this utility model includes a main body with two grippers controlled by a gripper opening and closing mechanism. Each gripper has a cutting edge for cutting the mulch film into long strips. In use, the farmer holds the main body forward and uses the cutting edges on the two opposing grippers to cut long strips of film between adjacent tobacco plants. The two ends of the long strip are then cut off to create a notch. Finally, the gripper opening and closing mechanism controls the two grippers to close together and clamp the cut strips for easy collection. This handheld film-tearing device is convenient, quick, and efficient. It effectively controls the size and specifications of the tear, prevents the film strip from tearing, and the two grippers can easily pick up and collect the cut strips. Attached Figure Description

Figure 1 To be continued Figure 5 An embodiment of this utility model provides a handheld film-tearing device for mulch film, which is particularly suitable for film-tearing operations of mulch film for flue-cured tobacco planting. It includes a main body 1, on which two opposing grippers 2 are provided and a gripper opening and closing control mechanism connected to the two grippers 2 for controlling the two grippers 2 to move closer to each other to form a clamping state or to move away from each other to form an open state. The two grippers 2 are provided with blades 21 that are oppositely arranged for cutting the mulch film into long strips of film. It is understood that in this embodiment, the handheld film-tearing device includes a main body 1, and two grippers 2, controlled by a gripper opening and closing control mechanism, are provided on the main body 1. Both grippers 2 are equipped with blades 21 for cutting the mulch film into long strips. In use, farmers can hold the main body 1 and push it forward, using the blades 21 on the two opposing grippers 2 to cut long strips of mulch film between adjacent tobacco plants. Then, the blades 21 are used to cut off both ends of the long strips to create long notches. Finally, the gripper opening and closing control mechanism controls the two grippers 2 to move closer together to form a clamping state, picking up and transferring the cut strips of mulch film for centralized recycling. This handheld film-tearing device is convenient, fast, and efficient. It can effectively control the size and specifications of the tear, prevents the film strip from tearing, and allows the two grippers 2 to pick up and transfer the cut strips of mulch film for recycling.

[0027] Please refer to the appendix. Figure 1 To be continued Figure 4 In one preferred embodiment, each of the two grippers 2 has a clamping plate portion 22, which are arranged opposite to each other. When the gripper opening and closing control mechanism controls the two clamping plates 22 to move closer together, the clamping action of the two clamping plates 22 clamps the mulch film. In another preferred embodiment, preferably, the blade portion 21 is formed at the bottom end of the clamping plate portion 22. It can be understood that, in this embodiment, since the blade portion 21 is formed at the bottom end of the clamping plate portion 22, the distance between the two blade portions 21 can be adjusted simultaneously by controlling the opening and closing of the two grippers 2 through the gripper opening and closing control mechanism.

[0028] Please refer to the appendix. Figure 3 Appendix Figure 4In one preferred embodiment, the main body 1 includes a cylindrical body 11, inside which a telescopic rod 12 is fitted. A mounting base 13 is provided at one end of the cylindrical body 11. Two grippers 2 are slidably mounted on the mounting base 13, and the two grippers 2 are connected to the telescopic rod 12 via a traction member 14. The telescopic rod 12 and the traction member 14 cooperate to form a gripper opening and closing control mechanism that controls the movement of the two grippers 2 by pulling the telescopic rod 12. In another preferred embodiment, preferably, the mounting base 13 has two gripper mounting portions for mounting the two grippers 2. Each gripper mounting portion includes two opposing side plates 15 and a guide slide rod 16 connecting the two side plates 15. The grippers 2 are slidably mounted on the guide slide rod 16, and an elastic reset member 17 is provided between the grippers 2 and the side plates 15 to automatically open the two grippers 2 away from each other to form an open state. In this embodiment, preferably, four guide slide rods 16 are provided between the two side plates 15 of the gripper mounting part. The upper end of the gripper 2 slides on the guide slide rods 16. The four guide slide rods 16 can effectively improve the smoothness of movement and the gripping stability of the gripper 2. However, those skilled in the art should understand that in other embodiments, other numbers of guide slide rods 16 may be provided between the two side plates 15 of the gripper mounting part. It is not limited to the specific implementation disclosed in this embodiment, as long as it can improve the smoothness of movement of the gripper 2 in the gripper mounting part.

[0029] Please refer to the appendix. Figure 4 In one preferred embodiment, the elastic reset member 17 is preferably a compression spring, with one end of the compression spring abutting against the inner side plate 15 in the gripper mounting part, and the other end abutting against the gripper 2.

[0030] Please refer to the appendix. Figure 4 In one preferred embodiment, the traction member 14 is preferably a traction rope, which is movably attached to the hanging hole 121 on the bottom of the telescopic rod 12, and the two ends of the traction rope pass through the corresponding side plates 15 and are fixedly connected to the two claws 2 on the mounting base 13. The top end of the telescopic rod 12 extends upward relative to the cylinder 11, and the top end of the telescopic rod 12 is provided with a handle 122.

[0031] Please refer to the appendix. Figure 3 Appendix Figure 4 In one preferred embodiment, a flange 123 is provided at the top end of the telescopic rod 12, and a screw-on (attached) part is provided near the top of the cylinder 11. Figure 4(The threaded connection between the movable sleeve 18 and the cylinder 11 is not shown.) A movable sleeve 18 is arranged vertically opposite to the flange 123. By rotating the movable sleeve 18, the connection height of the movable sleeve 18 relative to the cylinder 11 is changed, so that the maximum opening between the two grippers 2 can be adjusted by the abutment and limiting engagement between the top of the movable sleeve 18 and the flange 123. In use, the farmer can hold the cylinder 11 and push the two grippers 2 forward on the mulch film. After pushing it into place, the blade 21 is used to cut off the end of the long strip of film. Then, holding the cylinder 11 with one hand and pulling the handle 122 with the other hand, the telescopic pull rod 12 is used to pull the traction rope to retract, thereby driving the two grippers 2 to move closer together and clamp the long strip of film for transfer and collection. Furthermore, when it is necessary to adjust the distance between the two blades 21 (i.e., adjust the width of the strip of mulch film), the movable sleeve 18 can be rotated to change the connection height of the movable sleeve 18 on the cylinder 11. Since the top of the movable sleeve 18 limits the flange 123 at the top of the telescopic rod 12, the lower limit of the retraction of the telescopic rod 12 can be changed, thereby achieving the purpose of adjusting the maximum opening of the blades 21 at the bottom of the two grippers 2, so as to meet the cutting needs of strips of mulch film of different widths.

[0032] Please refer to the appendix. Figure 3 Appendix Figure 4 In one preferred embodiment, the side plate 15 of the gripper mounting part is provided with a steering wheel to facilitate the traction rope to pull the gripper 2.

[0033] Please refer to the appendix. Figure 4 Appendix Figure 5 In one preferred embodiment, the telescopic rod 12 is provided with a plurality of piston components 19 adapted to the interior of the cylinder 11. It can be understood that the cooperation between the piston components 19 and the cylinder 11 can effectively improve the telescopic stability of the telescopic rod 12 on the cylinder 11.
