Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tobacco planting equipment, specifically to a tobacco soil loosening and film breaking device. Background Technology
[0002] Tobacco seedling transplanting is generally carried out using the "well-cellar" method, which involves making holes in the raised, mulched ridges according to the spacing between transplanting plants. 15-20 days after transplanting, when the seedlings' growing points are 4-5 cm above the well-cellar, it is usually necessary to loosen the soil and expand the mulch.
[0003] Publication number CN210746380U discloses a large seedling film-breaking device. By fixing the film-breaking cylinder and the film-breaking cylinder at three points with a fixing ring, a non-concentric structure of the fixing ring and the film-breaking cylinder is achieved. By fixing the soil-loosening rod on the fixing ring, the soil of the plant is loosened at the same time as the film is broken, and the soil-loosening area is smaller than the film-breaking area. In this way, both soil loosening and film breaking are achieved.
[0004] However, when loosening the soil and breaking the film in tobacco seedling fields of different batches or environments, the required soil loosening depth is often different. If the required soil loosening depth in subsequent tobacco fields increases, since the height difference between the soil loosening rod and the film breaking blade in the above-mentioned patent is fixed, when the soil loosening rod is inserted into the ground, the depth of the film breaking blade into the soil also increases, which increases the resistance to loosening the soil and breaking the film. Utility Model Content
[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a tobacco soil loosening and film breaking device to solve the technical problem that the required soil loosening depth often varies when loosening and film breaking is carried out on tobacco seedling fields of different batches or environments. If the required soil loosening depth for subsequent tobacco fields increases, since the height difference between the soil loosening rod and the film breaking blade in the above-mentioned patent is fixed, when the soil loosening rod is inserted into the ground, the depth of the film breaking blade into the soil also increases, which increases the resistance to soil loosening and film breaking.

It has a film-breaking end, which is located on the side of the loosening end close to the rotating part. It can move relative to the loosening end along the rotation axis and can maintain the position after the movement relative to the loosening end.
[0011] In some embodiments, the loosening portion includes a loosening arm, a loosening component, and a locking component. The loosening arm is connected to the rotating portion and extends along the rotation axis. The loosening component is disposed at the end of the loosening arm away from the rotating portion and can move relative to the loosening arm along the rotation axis. The locking component connects the loosening component to the loosening portion and can lock the loosening component to the loosening arm and can unlock the loosening component.

[0015] In some embodiments, the loosening component is provided with a limiting groove along the rotation axis, and the inner wall of the adjustment channel is provided with a limiting block corresponding to the limiting groove, the limiting block being slidably disposed within the limiting groove.
[0016] In some embodiments, the soil loosening component includes an adjusting arm and a soil loosening knife. The adjusting arm is movably inserted into the adjusting channel, and the soil loosening knife is connected to the end of the adjusting arm away from the rotating part, thus forming the soil loosening end.

[0019] The loosening part and the membrane breaking part are installed on the movable seat.
[0020] In some embodiments, the fixed frame is provided with a movable channel in a direction away from the rotation axis, the sidewall of the movable channel is provided with a connecting hole, and the movable seat is provided with a plurality of adjusting screw holes at intervals in a direction away from the rotation axis, the plurality of adjusting screw holes selectively communicating with the connecting hole;
[0021] The rotating part also includes an adjusting bolt, which passes through the connecting hole and is screwed into the connected adjusting screw hole.
[0022] In some embodiments, the loosening portion can move relative to the membrane breaking portion in directions close to and away from the axis of rotation, and can maintain the position after the movement.
[0023] In some embodiments, the rotating part is provided with at least three mounting holes spaced apart along the arrangement direction of the loosening part and the membrane breaking part;

[0028] Compared with existing technologies, the tobacco soil loosening and film breaking device provided by this utility model allows for flexible adjustment of the height difference between the film breaking end and the film breaking end because the film breaking end can move relative to the soil loosening end along the rotation axis and maintain its position after movement. Thus, when loosening and breaking film in tobacco fields of different batches or environments, the height difference between the film breaking end and the soil loosening end can be adjusted according to the required loosening depth. This ensures that when the film breaking end just penetrates the film, the insertion depth of the soil loosening end is the required loosening depth, effectively preventing the film breaking end from inserting into the ground and increasing the rotational resistance of the rotating part, saving manpower, and improving the efficiency of the device in loosening and breaking film.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0037] To address the technical problem that the required soil loosening depth often varies when loosening soil and breaking film in tobacco seedling fields of different batches or environments, and that if the required soil loosening depth in subsequent tobacco fields increases, the fixed height difference between the loosening rod and the film-breaking blade in the aforementioned patent leads to an increased resistance as the loosening rod penetrates deeper into the ground. This invention provides a tobacco soil loosening and film-breaking device. When loosening soil and breaking film in tobacco fields of different batches or environments, the device can adjust the height difference between the film-breaking end and the loosening end according to the required soil loosening depth. This ensures that when the film-breaking end just penetrates the film, the insertion depth of the loosening end is the required soil loosening depth. This effectively avoids the film-breaking end inserting into the ground, which would increase the rotational resistance of the rotating part, save manpower, and improve the efficiency of the device in loosening soil and breaking film.
[0038] Please see Figures 1 to 3 , Figures 1 to 3 This is a schematic diagram of the structure of a tobacco loosening and film breaking device according to an embodiment of the present invention. The tobacco loosening and film breaking device includes a rotating part 1, a loosening part 2, and a film breaking part 3. The rotating part 1 has a rotation axis 11 and can rotate around the rotation axis 11. The loosening part 2 is connected to the rotating part 1 and has a loosening end 21. The loosening end 21 and the rotating part 1 are spaced apart along the rotation axis 11. The film breaking part 3 is connected to the rotating part 1 and is located on the side of the loosening part 2 away from the rotation axis 11. It has a film breaking end 31. The film breaking end 31 is located on the side of the loosening end 21 close to the rotating part 1 and can move relative to the loosening end 21 along the rotation axis 11. It can also maintain the position after the movement relative to the loosening end 21.
[0039] In the tobacco soil loosening and film breaking device provided by this utility model, since the film breaking end 31 can move relative to the soil loosening end 21 along the rotation axis 11 and can maintain the position after the movement relative to the soil loosening end 21, the height difference between the soil loosening end 21 and the film breaking end 31 can be flexibly adjusted. In this way, when loosening and breaking the film in tobacco fields of different batches or environments, the height difference between the film breaking end 31 and the soil loosening end 21 can be adjusted according to the required soil loosening depth, so that when the film breaking end 31 just penetrates the film, the insertion depth of the soil loosening end 21 is the required soil loosening depth. This effectively avoids the film breaking end 31 inserting into the ground and increasing the rotational resistance of the rotating part 1, saving manpower and improving the efficiency of the device in loosening and breaking the film.
[0040] It should be noted that, in one embodiment, the loosening part 2 can be configured as a hydraulic cylinder or a pneumatic cylinder in conjunction with the loosening blade 232, or other forms.

[0043] In one embodiment, the loosening arm 22 is provided with an adjustment channel 22a along the rotation axis 11, and the side wall of the adjustment channel 22a is provided with a plurality of locking screw holes 22b, which are spaced apart along the rotation axis 11; the loosening component 23 is provided with a limiting hole 23a corresponding to the locking screw hole 22b and is movably inserted into the adjustment channel 22a; the locking component 24 includes a locking bolt 241, which can be selectively screwed into the locking screw hole 22b and passes through the limiting hole 23a.
[0044] In this embodiment, by adjusting the position of the locking screw hole 22b that communicates with the limiting hole 23a, the depth of the loosening component 23 extending into the adjustment channel 22a is adjusted, thereby adjusting the height difference between the loosening component 23 and the membrane breaking end 31, and locking it by the locking bolt 241. The structure is simple and reliable, and the operation is convenient.

[0046] In this embodiment, the cooperation between the limiting block 221 and the limiting groove 23b prevents the loosening component 23 from rotating circumferentially relative to the loosening arm 22. It should be noted that the loosening component 23 can be configured as a loosening rod, a loosening blade 232, or a loosening drill bit. Specifically, in this solution, the loosening component 23 is configured as a loosening blade 232.
[0047] In one embodiment, the loosening component 23 includes an adjusting arm 231 and a loosening knife 232. The adjusting arm 231 is movably inserted into the adjusting channel 22a, and the loosening knife 232 is connected to the end of the adjusting arm 231 away from the rotating part 1 and forms the loosening end 21. A limiting hole 23a is formed in the adjusting arm 231.
[0048] In this embodiment, the adjusting arm 231 of the loosening component 23 is inserted into the adjusting channel 22a, and the limiting hole 23a is aligned with the required locking screw hole 22b as needed, and then locked by the locking bolt 241.

The loosening part 2 and the film breaking part 3 are mounted on the movable seat 13.
[0051] In this embodiment, the distance between the movable seat 13 and the rotation axis 11 can be adjusted as needed, thereby adjusting the rotation area of the loosening end 21 and the film breaking end 31. In other words, the size of the loosening area and the film breaking area can be adjusted to further improve flexibility.
[0052] In one embodiment, the fixed frame 12 is provided with a movable channel 12a in a direction away from the rotation axis 11, and the side wall of the movable channel 12a is provided with a connecting hole 12b. The movable seat 13 is provided with a plurality of adjusting screw holes 13a at intervals in a direction away from the rotation axis 11, and the plurality of adjusting screw holes 13a can selectively connect to the connecting hole 12b. The rotating part 1 also includes an adjusting bolt 15, which passes through the connecting hole 12b and is screwed into the connected adjusting screw holes 13a.
[0053] In this embodiment, the distance between the movable seat 13 and the rotation axis 11 is adjusted by adjusting the position of the adjusting screw hole 13a communicating with the connecting hole 12b, and then fixed by adjusting bolts 15, resulting in a stable and reliable structure. It should be noted that multiple loosening parts 2, membrane-breaking parts 3, and movable seats 13 are provided, with each set corresponding to a specific unit. Specifically, in this design, three loosening parts 2, membrane-breaking parts 3, and movable seats 13 are provided.
[0054] In one embodiment, the loosening part 2 can move relative to the film breaking part 3 in directions close to and away from the rotation axis 11, and can maintain the position after the movement.
[0055] In this embodiment, the distance between the loosening part 2 and the film breaking part 3 can also be flexibly adjusted, making the size adjustment of the loosening area and the film breaking area more flexible.
[0056] In one embodiment, the rotating part 1 is provided with at least three mounting holes 1a at intervals along the arrangement direction of the loosening part 2 and the film breaking part 3; both the loosening part 2 and the film breaking part 3 have screw sections, which can be selectively inserted into the mounting holes 1a, and a stopper 41 is provided on the screw section to stop on one side of the mounting hole 1a; the tobacco loosening and film breaking device also includes two mounting nuts 5, which are respectively screwed into the screw sections of the loosening part 2 and the film breaking part 3, and located on the side of the mounting hole 1a away from the stopper 41.
[0057] In this embodiment, the positions of the screw sections of the loosening part 2 and the film breaking part 3 can be adjusted, thereby allowing the distance between the loosening end 21 and the film breaking end 31 in the direction away from the rotation axis 11 to be flexibly adjusted, and fixed by assembling the nut 5 and the stop 41.
[0058] It should be understood that the screw section of the loosening part 2 is fixedly connected to the loosening arm 22. Furthermore, the membrane breaking part 3 can be configured as a membrane breaking heating rod, a membrane breaking knife, or a membrane breaking drill. Specifically, in this design, the membrane breaking knife includes a screw section, a membrane breaking arm, and a membrane breaking knife connected in sequence.

[0060] In this embodiment, the stop block 411 is inserted into the stop groove 1b. On the one hand, the axial movement of the screw section can be restricted by the stop block 411 and the mounting nut 5. On the other hand, the circumferential rotation of the screw section can be restricted by the stop block 411, so as to ensure the cutting ability of the film breaking knife and the loosening knife 232.
[0061] It should be noted that in this solution, the rotating part 1 also includes a drive arm 14, which is connected to the fixed frame 12.
[0062] To better understand this utility model, the following is combined with... Figures 1 to 5 The technical solution of this utility model is described in detail below:
[0063] In this design, the distance between the loosening section 2 and the film-breaking section 3 on the movable seat 13 can be adjusted as needed and fixed by the mounting nut 5 to adjust the size of the loosening and film-breaking areas. Simultaneously, the adjusting arm 231 can be moved so that the limiting hole 23a on the adjusting arm 231 connects to the corresponding locking screw hole 22b. The adjusting arm 231 is then locked to the loosening arm 22 by the locking bolt 241, achieving adjustment of the height difference between the loosening blade 232 and the film-breaking blade. This ensures that when the loosening blade 232 reaches the insertion depth, the film-breaking blade breaks the film precisely, preventing the film-breaking blade from being inserted too deeply and increasing the force required to rotate the drive arm 14, thus saving manpower.
