Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of forest tree planting, and in particular to a rapid mulching device for forest seedlings. Background Technology
[0002] In forestry seedling cultivation and afforestation projects, mulch film technology is widely used for moisture retention, temperature increase, weed suppression, and seedling growth promotion. To improve operational efficiency, various seedling mulching devices have been developed, typically including a frame, a film-laying roller machine, and a soil-covering mechanism, enabling automatic mulch film laying.
[0003] However, existing mulching devices for forest seedlings generally suffer from a significant technical deficiency: their film-laying mechanism is typically only compatible with a single fixed width of mulch film. Specifically, they only have one film-laying roller, which can only carry one specific width of mulch film. In actual forestry production, forest seedlings are planted in various ways, and the width of the furrows varies depending on the tree species or cultivation techniques. Therefore, during the mulching process, sometimes a wider mulch film is used, and sometimes a narrower one. The existing mulching devices cannot readily switch between wide and narrow mulch films as needed, resulting in significant limitations in their application, inconvenience, and poor practicality. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a rapid mulching device for forest seedlings that allows for the selection of wide or narrow mulch film as needed, is convenient to use, has few limitations, and is highly practical.
[0005] This utility model discloses a rapid mulching device for forest seedlings, including a mounting frame; it also includes a wide film fixing mechanism, a narrow film fixing mechanism, a rotating mechanism, and a soil covering mechanism. The rotating mechanism is mounted on the mounting frame, and both the wide film fixing mechanism and the narrow film fixing mechanism are mounted on the rotating mechanism. The rotating mechanism has a rotating function, the wide film fixing mechanism has the function of fixing wide mulch film, and the narrow film fixing mechanism has the function of fixing narrow mulch film. The soil covering mechanism is mounted on the right side of the mounting frame and has the function of covering soil. When mulching on rotary-tilled land, a roll with wide mulch film is fixed on the wide film fixing mechanism, and a roll with narrow mulch film is fixed on the narrow film fixing mechanism. The mounting frame is fixedly mounted on the left side of the tractor. When needed... When using wide plastic film for mulching, open the rotating mechanism to move the wide film fixing mechanism to the left side of the rotating mechanism, allowing the wide film to fall onto the ground. Simultaneously, the soil covering mechanism covers both sides of the wide film. At the same time, the tractor moves the mounting frame to the right, which in turn moves the rotating mechanism and the wide film fixing mechanism to the right, causing the wide film on the roll to continuously unroll and fall onto the ground to complete the mulching. When using narrow plastic film for mulching, open the rotating mechanism to rotate the narrow film fixing mechanism to the left side of the rotating mechanism, and then use the narrow plastic film for mulching in the same way. It can be used with either wide or narrow plastic film as needed, making it convenient, with few limitations, and highly practical.
[0006] Preferably, the wide film fixing mechanism includes an unwinding roller A, a screw A, a fixing plate A, and a clamping plate A. The screw A is fixedly installed at the front end of the unwinding roller A, the fixing plate A is fixedly installed at the rear end of the unwinding roller A, and the clamping plate A is screwed onto the screw A. When fixing the roll with the wide film wound on it, the roll has a cavity that communicates with the front end. The roll is placed on the unwinding roller A so that the unwinding roller A passes through the cavity on the roll. Then, the clamping plate A is installed on the screw A, and the clamping plate A is rotated so that the clamping plate A contacts the front end of the roll. The roll with the wide film wound on it is clamped and fixed by the fixing plate A and the clamping plate A.
[0007] Preferably, the narrow film fixing mechanism includes an unwinding roller B, a screw B, a fixing plate B, and a clamping plate B. The fixing plate B is fixedly installed at the rear of the unwinding roller B, the screw B is fixedly installed at the front end of the unwinding roller B, and the clamping plate B is screwed to the screw B. When fixing the roll with the narrow film wound on it, the roll has a cavity that communicates with the front and rear. The roll is placed on the unwinding roller B so that the unwinding roller B passes through the cavity on the roll. Then, the clamping plate B is installed on the screw B, and the clamping plate B is rotated so that the clamping plate B contacts the front end of the roll. The roll with the narrow film wound on it is clamped and fixed by the clamping plate B and the fixing plate B.
[0008] Preferably, the rotating mechanism includes a servo indexing turntable, a rotating shaft, and a connecting frame. The servo indexing turntable is fixedly mounted on the mounting frame, the rotating shaft is mounted on the rotating end at the front of the servo indexing turntable, and the connecting frame is fixedly mounted on the front end of the rotating shaft. Unwinding roller A and unwinding roller B are respectively rotatably mounted on the left and right sides of the connecting frame. When unwinding and covering the film through the narrow film roll, the narrow film wound on the roll falls to the ground. Then, the tractor moves to the right, causing the mounting frame to drive the servo indexing turntable and the rotating shaft. Move to the right, the rotating shaft drives the connecting frame and unwinding roller B to move to the right, and at the same time, cover the narrow mulch film on the ground with soil, so that the narrow mulch film on the ground pulls the narrow mulch film roll, and then unwinds the narrow mulch film on the narrow mulch film roll, so that the narrow mulch film falls on the ground to cover the film; similarly, when using wide mulch film for covering, turn on the servo indexing turntable, so that the rotating shaft drives the connecting frame to rotate, so that the unwinding roller A rotates around the axis of the rotating shaft to the left side of the connecting frame, and unwinds the wide mulch film roll on the unwinding roller A as described above.
[0009] Preferably, the soil covering mechanism includes two scrapers, a distance adjustment mechanism, and a lifting mechanism. The distance adjustment mechanism is mounted on the lifting mechanism and is used to raise and lower the distance adjustment mechanism. Both scrapers are mounted on the distance adjustment mechanism and are used to adjust the distance between the two scrapers. Both scrapers are installed at an angle, are symmetrical front to back, and are installed in a V-shape, with the right side of the V-shape being the opening side. When the mulch film is placed on the ground, the lifting mechanism is opened, causing the distance adjustment mechanism to lower the two scrapers until they contact the soil. As the tractor moves to the right, the tractor drives the mounting frame, lifting mechanism, distance adjustment mechanism, and two scrapers to move to the right. During the rightward movement, the two scrapers push the soil on both sides of the mulch film inward, thereby covering the front and back of the ground with soil, completing the soil covering of the mulch film and improving convenience.
[0010] Preferably, the distance adjustment mechanism includes a lifting plate, a fixed plate, a servo motor, a lead screw, two sliding blocks, and a track. The fixed plate is fixedly installed at the lower end of the lifting plate, the servo motor is fixedly installed on the fixed plate, and the lead screw is rotatably installed on the fixed plate. The front and rear parts of the lead screw are respectively provided with external threads in opposite directions. The power output end of the servo motor is connected to the lead screw. The two sliding blocks are respectively screwed to the front and rear parts of the lead screw. Both sliding blocks are slidably installed on the track, which is fixedly installed at the lower end of the lifting plate. When covering the ground with mulch film, the servo motor is turned on, and the servo motor drives the lead screw to rotate. The rotating lead screw causes the two sliding blocks to drive the two scrapers to adjust the distance so that the distance between the two scrapers is adapted to the width of the mulch film. The distance between the two scrapers can be adjusted according to the width of the mulch film, which can be applied to mulch films of different widths. It is convenient to use, has low limitations, and is highly practical.
[0011] Preferably, the lifting mechanism includes a mounting plate, a hydraulic cylinder, a lifting rod, and a sliding rod. The mounting plate is fixedly installed on the left side of the mounting frame, the hydraulic cylinder is fixedly installed on the upper part of the mounting plate, and the lifting rod and sliding rod are both slidably installed on the mounting plate. The lifting plate is fixedly installed on the lower end of the lifting rod and sliding rod. When adjusting the height of the two scrapers, the hydraulic cylinder is opened, causing the lifting rod to drive the lifting plate down, which in turn causes the track and the two sliding blocks to descend, thereby causing the two scrapers to descend to contact the soil on the ground. This allows the scrapers to scrape the soil onto the mulch film for covering when they move to the right, facilitating the raising and lowering of the scrapers.
[0012] Preferably, it also includes a vertical plate and a guide roller. The guide roller is rotatably mounted on the vertical plate, and the vertical plate is fixedly mounted on the lower end of the mounting frame. The vertical plate is located on the left side of the rotating mechanism. When the mulch film is unwound on the unwinding roller A or the unwinding roller B, the mulch film falls onto the soil after passing through the guide roller, which facilitates the guidance of the mulch film during mulching and facilitates the control of the mulch film unwinding trajectory.
[0013] Compared with the prior art, the advantages of this utility model are: it can choose to use wide or narrow mulch film as needed, which is convenient to use, has low limitations, and is highly practical. Attached Figure Description

[0016] To facilitate understanding of this invention, a more complete description will be provided below with reference to the accompanying drawings. This invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this invention more thorough and complete. Example 1
[0017] like Figures 1 to 6 This utility model's rapid mulching device for forest seedlings includes a mounting frame 1, a wide film fixing mechanism, a narrow film fixing mechanism, a rotating mechanism, and a soil covering mechanism. The rotating mechanism is mounted on the mounting frame 1, and both the wide film fixing mechanism and the narrow film fixing mechanism are mounted on the rotating mechanism. The rotating mechanism has a rotating function, the wide film fixing mechanism has the function of fixing wide mulch film, and the narrow film fixing mechanism has the function of fixing narrow mulch film. The soil covering mechanism is mounted on the right side of the mounting frame 1 and has the function of covering soil. When mulching on rotary-tilled land, the roll with wide mulch film is fixed on the wide film fixing mechanism, and the roll with narrow mulch film is fixed on the narrow film fixing mechanism. The mounting frame 1 is fixedly mounted on the left side of the tractor. When needed... When using wide plastic film for mulching, the rotating mechanism is activated, causing the wide film fixing mechanism to move the roll containing the wide plastic film to the left side of the rotating mechanism. As the wide plastic film falls onto the ground, soil is simultaneously covered on both sides of the film by the soil covering mechanism. At the same time, the tractor moves the mounting frame 1 to the right, which in turn moves the rotating mechanism and the wide film fixing mechanism to the right, causing the wide plastic film on the roll to continuously unroll and fall to the ground, completing the mulching process. When using narrow plastic film for mulching, the rotating mechanism is activated, causing the narrow film fixing mechanism to rotate the roll containing the narrow plastic film to the left side of the rotating mechanism. The narrow plastic film can then be used in the same manner. It allows for the selection of either wide or narrow plastic film for mulching as needed, offering convenience, low limitation, and high practicality.
[0018] like Figure 3 The wide film fixing mechanism includes an unwinding roller A2, a screw A3, a fixing plate A4, and a clamping plate A5. The screw A3 is fixedly installed at the front end of the unwinding roller A2, the fixing plate A4 is fixedly installed at the rear end of the unwinding roller A2, and the clamping plate A5 is screwed to the screw A3. When fixing the roll with wide film, the roll has a cavity that communicates with the front and rear. The roll is placed on the unwinding roller A2 so that the unwinding roller A2 passes through the cavity on the roll. Then, the clamping plate A5 is installed on the screw A3. The clamping plate A5 is rotated so that it contacts the front end of the roll. The roll with wide film is clamped and fixed by the fixing plate A4 and the clamping plate A5.
[0019] like Figure 1 and Figure 3The narrow film fixing mechanism includes an unwinding roller B6, a screw B7, a fixing plate B8, and a clamping plate B9. The fixing plate B8 is fixedly installed at the rear of the unwinding roller B6, the screw B7 is fixedly installed at the front of the unwinding roller B6, and the clamping plate B9 is screwed onto the screw B7. When fixing the roll with the narrow mulch film, the roll has a cavity that communicates with the front end. The roll is placed on the unwinding roller B6, allowing the unwinding roller B6 to pass through the cavity on the roll. Then, the clamping plate B9 is installed on the screw B7. The clamping plate B9 is rotated until it contacts the front end of the roll, thus clamping and fixing the roll with the narrow mulch film through the clamping plate B9 and the fixing plate B8. Both the clamping plate A5 and the clamping plate B9 have threaded holes in their middle portions.
[0020] like Figure 1 and Figure 3 The rotating mechanism includes a servo indexing turntable 10, a rotating shaft 11, and a connecting frame 12. The servo indexing turntable 10 is fixedly mounted on the mounting frame 1. The rotating shaft 11 is mounted on the rotating end at the front of the servo indexing turntable 10. The connecting frame 12 is fixedly mounted on the front end of the rotating shaft 11. Unwinding rollers A2 and B6 are rotatably mounted on the left and right sides of the connecting frame 12, respectively. When unwinding and covering the film through the narrow film roll, the narrow film wound on the roll falls to the ground. Then, the tractor moves to the right, causing the mounting frame 1 to drive the servo indexing turntable 10 and the rotating shaft. 11 moves to the right, and the rotating shaft 11 drives the connecting frame 12 and the unwinding roller B6 to move to the right. At the same time, soil is applied to the narrow mulch film on the ground, so that the narrow mulch film on the ground pulls the narrow mulch film roll, and then the narrow mulch film is unwound on the narrow mulch film roll, so that the narrow mulch film falls on the ground for mulching. Similarly, when using wide mulch film for mulching, the servo indexing turntable 10 is turned on, so that the rotating shaft 11 drives the connecting frame 12 to rotate, so that the unwinding roller A2 rotates around the axis of the rotating shaft 11 to the left side of the connecting frame 12, and the wide mulch film roll is unwound on the unwinding roller A2 for mulching as described above.
[0021] like Figure 1 and Figure 4 The soil covering mechanism includes two scrapers 13, a distance adjustment mechanism, and a lifting mechanism. The distance adjustment mechanism is mounted on the lifting mechanism and is used to raise and lower the distance adjustment mechanism. Both scrapers 13 are mounted on the distance adjustment mechanism and are used to adjust the distance between the two scrapers 13. Both scrapers 13 are installed at an angle, are symmetrical front and back, and are installed in a V-shape, with the right side of the V-shape being the opening side. When the mulch film is placed on the ground, the lifting mechanism is opened, causing the distance adjustment mechanism to lower the two scrapers 13 until they contact the soil. As the tractor moves to the right, the tractor drives the mounting frame 1, the lifting mechanism, the distance adjustment mechanism, and the two scrapers 13 to move to the right. During the rightward movement, the two scrapers 13 push the soil on both sides of the mulch film inward, thereby covering the front and back parts of the ground with soil, completing the soil covering of the mulch film and improving convenience.
[0022] like Figure 1 , Figure 4 and Figure 5 The distance adjustment mechanism includes a lifting plate 14, a fixed plate 15, a servo motor 16, a lead screw 17, two sliding blocks 18, and a track 19. The fixed plate 15 is fixedly installed at the lower end of the lifting plate 14, the servo motor 16 is fixedly installed on the fixed plate 15, and the lead screw 17 is rotatably installed on the fixed plate 15. The front and rear parts of the lead screw 17 are respectively provided with external threads with opposite directions of rotation. The power output end of the servo motor 16 is connected to the lead screw 17. The two sliding blocks 18 are respectively screwed to the front and rear parts of the lead screw 17. Both sliding blocks 18 are slidably installed on the track 19, which is fixedly installed at the lower end of the lifting plate 14. When covering the ground with mulch film, the servo motor 16 is turned on, and the servo motor 16 drives the lead screw 17 to rotate. The rotating lead screw 17 causes the two sliding blocks 18 to drive the two scrapers 13 to adjust the distance so that the distance between the two scrapers 13 is adapted to the width of the mulch film. The distance between the two scrapers 13 can be adjusted according to the width of the mulch film, which can be used for mulch film of different widths. It is convenient to use, has low limitations, and is highly practical.
[0023] like Figure 1 and Figure 4 The lifting mechanism includes a mounting plate 20, a hydraulic cylinder 21, a lifting rod 22, and a sliding rod 23.

The lifting plate 14 is fixedly installed on the lower end of the lifting rod 22 and the sliding rod 23. When adjusting the height of the two scrapers 13, the hydraulic cylinder 21 is opened, causing the lifting rod 22 to drive the lifting plate 14 to descend, which in turn causes the track 19 and the two sliding blocks 18 to descend, thereby causing the two scrapers 13 to descend to contact the soil on the ground. When the scrapers 13 move to the right, they can scrape the soil onto the mulch film for covering, which facilitates the lifting and lowering of the scrapers 13. Example 2
[0024] Based on Example 1, such as Figure 1 and Figure 6 It also includes a vertical plate 24 and a guide roller 25. The guide roller 25 is rotatably mounted on the vertical plate 24, and the vertical plate 24 is fixedly mounted on the lower end of the mounting frame 1. The vertical plate 24 is located on the left side of the rotating mechanism. When the mulch film is unwound on the unwinding roller A2 or the unwinding roller B6, the mulch film falls onto the soil after passing through the guide roller 25, which facilitates the guidance of the mulch film during mulching and facilitates the control of the mulch film unwinding trajectory.
[0025] It should be noted that the electrical equipment in this case, such as the servo indexing turntable 10, servo motor 16, and hydraulic cylinder 21, are all connected to an external controller, which coordinates and controls the operation of each electrical device.
