Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of tobacco planting, especially to a mulching film laying device for tobacco planting. BACKGROUND

[0002] In the process of tobacco planting, mulching film covering technology is widely used to improve soil temperature, maintain soil humidity and inhibit weed growth. In order to achieve efficient and accurate mulching film laying, a mulching film laying machine emerges as the times require. This device can automatically lay mulching film on each ridge of soil in the tobacco field and cover the soil on both sides of each ridge to the two sides of the mulching film through a mechanical device, thereby fixing the position of the mulching film and avoiding displacement or damage of the mulching film due to wind or other external factors.

[0003] However, although the existing mulching film laying machine has made significant progress in automation and efficiency, there are still some problems to be solved in practical application, the most prominent of which is the difficulty in accurately controlling the height and thickness of the covering soil. In the process of tobacco planting, the height and thickness of the covering soil on both sides of the mulching film have an important influence on the growth and development of tobacco. If the covering soil is too high or too thick, it will block sunlight from shining on the surface of the mulching film, thereby affecting the soil warming effect under the mulching film, which is not conducive to the normal growth of tobacco seedlings. In addition, too thick covering soil may also lead to a decrease in soil permeability, affecting root development and even causing disease problems. On the contrary, if the covering soil is insufficient, the mulching film may not be fixed firmly and may be easily loosened or damaged under the action of wind, thereby reducing the effect of mulching film covering. The soil covering mechanism of the existing mulching film laying machine usually adopts a fixed structure design and cannot be flexibly adjusted according to different terrain characteristics or planting requirements. This limitation makes the soil covering process lack precision and difficult to meet the strict requirements of tobacco planting on the quality of mulching film laying. SUMMARY

[0004] Therefore, the utility model provides a mulching film laying device for tobacco planting, which can overcome the shortcomings of the existing mulching film laying machine that cannot adjust the height and thickness of the covering soil according to different terrain characteristics or planting requirements.

[0005] The technical implementation scheme of the utility model is as follows: a mulching film laying device for tobacco planting, comprising: a mulching film laying machine body; two mounting racks, which are symmetrically connected to the mulching film laying machine body; a sliding rack, which is slidingly connected to the mounting rack; a drive motor, which is installed at the top of the sliding rack; a soft brush, which is connected to the output shaft of the drive motor; a sliding plate, which is slidingly connected to the sliding rack and has a side surface in contact with the side surface of the mounting rack; a connecting spring, which has two ends respectively connected to the sliding rack and the sliding plate; a lifting assembly, which is provided on the mounting rack and used to drive the sliding rack to lift; and a scraping mechanism, which is provided on the mounting rack and used to scrape the covering soil on both sides of the mulching film.

[0006] Optionally, the lifting assembly includes: a servo motor mounted on the top of the mounting frame; a lead screw rotatably connected inside the mounting frame, with the upper end of the lead screw connected to the output shaft of the servo motor; and a lifting block slidably connected to the mounting frame, the sliding direction of the lifting block being perpendicular to the sliding direction of the sliding frame, and the lifting block being threadedly connected to the lead screw and slidably connected to the sliding frame.

[0007] Optionally, the leveling mechanism includes: a movable plate slidably connected to the top of the mounting frame, the sliding direction of the movable plate being parallel to the sliding direction of the sliding frame, and a strip groove being formed on the movable plate; a scraper connected to the side of the movable plate; and a fixing component disposed on the mounting frame for fixing the movable plate.

[0008] Optionally, the fixing components include: a fastening bolt threaded to the top of the mounting bracket; a pressure plate rotatably connected to the fastening bolt, with the bottom of the pressure plate contacting the top of the movable plate; and a block symmetrically connected to the bottom of the pressure plate, with the block located within the strip groove.

[0009] Optionally, the side of the two mounting brackets that are close to each other is an inclined surface, and the sliding bracket is in close contact with the inclined surface on the mounting bracket.

[0010] Optionally, it also includes a baffle connected to the sliding frame, and the baffle blocks the side of the two mounting frames that are close to each other.

[0011] The present invention has the following advantages: 1. The present invention can precisely process the soil covering on both sides of the mulch film by the coordinated use of a scraper and a soft brush. The scraper scrapes the excess soil backward to adjust the soil covering thickness, while the soft brush rotates to evenly distribute the soil to both sides of the mulch film, further optimizing the height and flatness of the soil covering. This design can ensure that the soil covering is neither too high to affect sunlight exposure, nor too low to cause the mulch film to be not firmly fixed, thus providing ideal mulch film laying conditions for tobacco planting.

[0012] 2. The inclined design of the mounting frame of this utility model, together with the sliding frame and connecting spring, enables the soft brush to automatically adjust its horizontal position and vertical distance according to the inclination of the soil surface. During the lifting and lowering of the sliding frame, the connecting spring provides elastic support, making the sliding frame move closely against the inclined surface of the mounting frame, thereby preventing the soft brush from being too close or too far from the soil surface. This mechanism can effectively avoid damage to the mulch film caused by improper distance of the soft brush, while ensuring the equipment's ability to adapt to different terrains.

[0013] 3. This utility model, through the cooperation of the baffle, screw, and lifting block, can ensure the stability of the mulch film laying process. The design of the baffle effectively prevents soil from splashing onto the threads of the screw, avoiding the problem of the lifting block getting stuck due to soil accumulation, thereby ensuring the normal lifting and lowering function of the screw driving the lifting block.

Detailed Implementation

[0021] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] Example: A mulch film laying device for tobacco planting, such as Figures 1-5As shown, the machine includes a film-laying machine body 1, mounting frames 2, sliding frames 3, drive motors 4, soft brushes 5, sliding plates 6, connecting springs 7, lifting components, and a leveling mechanism. Mounting frames 2 are symmetrically connected to the front left and right sides of the film-laying machine body 1. Sliding frames 3 are slidably connected to each of the two mounting frames 2 and can slide up and down. Drive motors 4 are mounted on the top sides of the two sliding frames 3 that are close to each other. Soft brushes 5 are connected to the output shafts of the two drive motors 4. Sliding plates 6 are slidably connected to the sides of the two sliding frames 3 that are far apart from each other. The sides of the sliding plates 6 contact the sides of their corresponding mounting frames 2. Two soft brushes 5 are wrapped around the sides of the two sliding frames 3 that are far apart from each other. A connecting spring 7 is connected to a sliding frame 3 and a sliding plate 6 at its two ends respectively. The sides of the two mounting frames 2 that are close to each other are inclined. During the lifting and lowering process, the sliding frame 3 can move left and right with the inclined surface of the mounting frame 2 by the elastic force of the connecting spring 7, so as to ensure that the sliding frame 3 is in close contact with the inclined surface of the mounting frame 2. This can adjust the horizontal position of the soft brush 5 and ensure that its distance from the soil surface is always within a reasonable range, preventing the soft brush 5 from being too close to the soil surface and causing damage to the mulch film. The lifting component is used to drive the sliding frame 3 to lift and lower, and the leveling mechanism is used to level the soil covering on both sides of the mulch film.

[0023] like Figure 2 and Figure 3 As shown, the lifting assembly includes a servo motor 8, a lead screw 9, and a lifting block 10. A servo motor 8 is mounted on the top of each of the two mounting brackets 2, and a lead screw 9 is rotatably connected to the lower part of each of the two mounting brackets 2. Each lead screw 9 corresponds to one of the servo motors 8, and the upper end of each lead screw 9 is connected to the output shaft of its corresponding servo motor 8. Lifting blocks 10 are slidably connected inside each of the two mounting brackets 2 and can slide left and right. Each lifting block 10 corresponds to one of the lead screws 9, and the lifting block 10 is threadedly connected to its corresponding lead screw 9. The lifting block 10 is T-shaped, and it corresponds to one of the sliding frames 3, with the lifting block 10 slidably connected to its corresponding sliding frame 3.

[0024] like Figure 4 and Figure 5 As shown, the leveling mechanism includes a movable plate 11, a scraper 12, and a fixing assembly. The top of each of the two mounting brackets 2 is slidably connected to the movable plate 11. Each of the two movable plates 11 has a strip groove 1101. Each of the two movable plates 11 is connected to the front side of the two movable plates 11. The upper half of each of the two scrapers 12 is vertical, and the lower half of each of the two scrapers 12 is inclined to the opposite side. The fixing assembly is used to fix the movable plate 11. The fixing assembly includes fastening bolts 13, pressure plates 14, and blocks 15. The top of each of the two mounting brackets 2 is threadedly connected to the fastening bolts 13. Each of the two fastening bolts 13 is rotatably connected to the middle of the pressure plates 14, and the bottom of the pressure plates 14 contacts the top of the movable plate 11. Each of the bottoms of the two pressure plates 14 is symmetrically connected to blocks 15, and the blocks 15 are located in the strip groove 1101.

[0025] like Figure 6 As shown, it also includes a baffle 16. The baffle 16 is connected to the middle of both sliding brackets 3. The baffle 16 is U-shaped and blocks the side of the two mounting brackets 2 that are close to each other.

[0026] Initially, the connecting spring 7 is compressed. When the mulch film needs to be laid in the tobacco field, first, the mulch film laying machine body 1 is moved to the designated position, then the roll of mulch film is installed on the mulch film laying machine body 1, and then one end of the mulch film is pulled out and fixed to the ground. Then, according to the terrain features or planting needs, the servo motor 8 can be controlled to drive the lead screw 9 to rotate forward and backward. The lead screw 9 can drive the lifting block 10 to rise and fall. The lifting block 10 can drive the sliding frame 3, the drive motor 4, the soft brush 5, and the sliding plate 6 to rise and fall, thereby adjusting the height of the soft brush 5. Since the side of the two mounting frames 2 that are close to each other is inclined, the sliding frame 3 can be driven by the elastic force of the connecting spring 7 during the lifting and falling process. The sliding frame 3 moves left and right along the inclined surface of the mounting frame 2, thereby driving the drive motor 4, the soft brush 5, and the sliding plate 6 to move left and right, adjusting the horizontal position of the soft brush 5. Since the surface of the ridge soil in the tobacco field is inclined, the distance between the soft brush 5 and the ridge soil surface can be controlled within a suitable range. Then, the fastening bolt 13 can be rotated. Since the block 15 is located in the strip groove 1101, it can limit the pressure plate 14 and the block 15, preventing the pressure plate 14 from rotating with the fastening bolt 13. At this time, the fastening bolt 13 will move upward, driving the pressure plate 14 to move upward and disengage from the moving plate 11, thereby releasing the fixation of the moving plate 11. Then, the moving plate 11 can be controlled to move left and right. The machine moves, causing the scraper 12 to move left and right to adjust the distance between the scraper 12 and the surface of the soil ridge. After adjustment, the fastening bolt 13 is reversed and reset, causing the pressure plate 14 to move downward and press down on the moving plate 11, thus fixing the position of the moving plate 11 and the scraper 12. Then, the machine body 1 moves backward, automatically laying the mulch film on each ridge and covering the left and right sides of the mulch film with the soil on both sides of each ridge, thus fixing the position of the mulch film. The machine body 1 can drive the soft brush 5 and the scraper 12 to move backward. When the scraper 12 contacts the soil on the left and right sides of the mulch film, it can scrape away the excess soil backward, thus accurately laying the mulch film. The thickness of the soil covering on the left and right sides of the mulch film can be controlled. At the same time, the soft brush 5 can be driven to rotate by the drive motor 4. When the soft brush 5 comes into contact with the soil on the left and right sides of the mulch film, it can brush away the soil that is higher than the bottom of the soft brush 5 to the left and right sides, thereby accurately controlling the soil covering height on the left and right sides of the mulch film. Through the coordinated work of the scraper 12 and the soft brush 5, the uniformity of the soil covering can be ensured, and the quality of the mulch film laying can meet the needs of tobacco planting. The baffle 16 can prevent the soil brushed away by the soft brush 5 from splashing onto the thread of the screw 9, ensuring that the lifting block 10 can move up and down normally along the screw 9. The bristles of the soft brush 5 are relatively soft, so even if they come into contact with the mulch film laid on the ridge soil, they will not damage the mulch film.
