Description

Technical Field

[0001] This utility model relates to the field of planting mulching technology, and in particular to a mulching device for improving the germination rate of Angelica sinensis seeds. Background Technology

[0002] Angelica sinensis, a traditional Chinese medicinal herb, is widely used in the field of traditional Chinese medicine for its roots, known for its effects in regulating qi and blood, and promoting blood circulation. In the cultivation of Angelica sinensis, mulching technology has gradually gained widespread application to improve seed germination rates, promote healthy seedling growth, and address the impact of climate change on crop growth cycles. Mulching effectively reduces soil moisture evaporation and maintains soil humidity, which is particularly important in arid or semi-arid regions, significantly improving seed survival rates and germination speed. Currently, mulching is typically done using a mulching machine. A plastic film roller is installed on the machine; as the machine moves forward, it drives the roller to rotate, laying the film on the slope. However, existing mulching machines cannot adjust the height of the plastic film roller according to the slope height, nor can they replace the roller with a suitable width based on the actual coverage width, affecting film laying and thus impacting seed germination rates. Utility Model Content

[0003] The purpose of this invention is to provide a film covering device for improving the germination rate of Angelica sinensis seeds. The device can adjust the height of the plastic film roller as needed and replace it with plastic film rollers of different widths to better complete the film laying and improve the germination rate of seeds.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A film covering device for improving the germination rate of Angelica sinensis seeds includes a support frame. A first limiting slide opening is provided on one side of each of the left and right ends of the support frame. A first threaded rod, horizontally arranged, is rotatably connected to the upper end of the support frame near the corresponding first limiting slide opening. A second threaded rod, with the opposite thread arrangement, is horizontally arranged at the free end of the first threaded rod. A first threaded sleeve is threadedly connected to the outer side of the first threaded rod, and a second threaded sleeve is threadedly connected to the outer side of the second threaded rod. A third threaded rod, horizontally arranged and movably connected to the corresponding first limiting slide opening, is rotatably connected inside the support frame. A fourth threaded rod, with the opposite thread arrangement and movably connected to the corresponding first limiting slide opening, is horizontally arranged at the end of the third threaded rod away from the support frame.

[0006] The outer side of the third threaded rod is threaded with a third threaded sleeve, and the outer side of the fourth threaded rod is threaded with a fourth threaded sleeve. The outer side of the first threaded sleeve is rotatably connected to a first connecting rod rotatably connected to the third threaded sleeve. The outer side of the second threaded sleeve is rotatably connected to a second connecting rod rotatably connected to the fourth threaded sleeve. The lower ends of the third threaded sleeve and the fourth threaded sleeve are each provided with a first support rod. The lower end of each first support rod is rotatably connected to a frustum-shaped clamping block that is horizontally arranged and frustum-shaped. A plastic film roller is detachably arranged between the two frustum-shaped clamping blocks.

[0007] Each first support rod has a second support rod horizontally installed at its lower end, each second support rod has a first limiting sleeve installed at its free end, each first limiting sleeve has a third support rod slidably connected inside, each third support rod has a film covering wheel rotatably connected at its lower end, the support frame has an adjustment device for adjusting the height of the film covering wheel inside, and each third support rod has a soil covering device installed at its lower end.

[0008] By adopting the above technical solution, in use, first determine the required film width, select a plastic film roller of appropriate width, and then install the plastic film roller. By rotating the third threaded rod, due to the limiting effect of the first connecting rod, the third threaded rod will rotate relative to the third threaded sleeve, causing the third threaded sleeve to move relative to the third threaded rod. At the same time, the third threaded rod drives the fourth threaded rod to rotate. Due to the limiting effect of the second connecting rod, the fourth threaded rod drives the fourth threaded sleeve to move relative to it, thereby causing the third threaded sleeve and the fourth threaded sleeve to move towards each other. Through the first support rod, the frustum-shaped clamping blocks move closer together, allowing the frustum-shaped clamping blocks to clamp the plastic film roller. At the same time, the first support rod drives the second support rod to move, and the second support rod moves through the third support rod, thereby adjusting the distance between the film covering rollers to be equal to the distance between the plastic film rollers. The third support rod drives the adjustment of the spacing between the soil covering devices; then by rotating... The first threaded rod drives the first threaded sleeve to move relative to it. The first threaded rod drives the second threaded rod to rotate, and the second threaded rod drives the first threaded sleeve to move relative to it, thereby causing the first threaded sleeve and the second threaded sleeve to move towards or away from each other. The first threaded sleeve drives the first connecting rod to rotate relative to it, and the second threaded sleeve drives the first connecting rod to rotate relative to it. Thus, through the first connecting rod and the second connecting rod, the third threaded sleeve and the fourth threaded sleeve are moved up and down respectively, thereby causing the third threaded rod and the fourth threaded rod to slide in the corresponding first limit sliding mouth to adjust the height of the plastic film roller. When laying the film, the support moves and pulls the plastic film roller. The plastic film roller drives the frustum-shaped clamping block to rotate, and the film is removed from the plastic film roller for laying. The film covering wheel rotates and presses down on both sides of the film. Then, through the soil covering device, the two sides of the film are covered with soil to lay the film flat.

[0009] A further feature of this invention is that a connecting frame is rotatably connected to one end of the bracket near the plastic film roller.

[0010] A further feature of this invention is that a first handle is provided at the end of the first threaded rod away from the second threaded rod and at the end of the third threaded rod away from the fourth threaded rod.

[0011] A further feature of this invention is that the adjusting device includes a second limiting slide opening on both the left and right ends of the bracket away from the first limiting slide opening, a fourth support rod that is horizontally arranged and slidably connected inside the bracket and slidably connected to each of the second limiting slide openings, a second limiting sleeve that is slidably connected to the fourth support rod at the upper end of each third support rod, a fifth threaded rod that is threadedly connected to and rotatably connected to the fourth support rod at the upper end of the bracket, and a second handle that is provided at the upper end of the fifth threaded rod.

[0012] A further feature of this invention is that the soil covering device includes a fifth support rod horizontally arranged at the lower end of the third support rod, a third limiting sleeve arranged at the end of each fifth support rod away from the corresponding fourth support rod, an L-shaped rod arranged vertically slidably connected inside each second sleeve, a soil covering disc arranged at the lower end of each L-shaped rod, and a fixing bolt threadedly connected to the outside of each limiting sleeve.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] Firstly, it allows for convenient adjustment of the height of the plastic film roller. By rotating the first threaded rod, the first threaded rod drives the second threaded rod to rotate. Due to the limiting effect of the first and second connecting rods, the first threaded sleeve moves relative to the first threaded rod, and the second threaded sleeve moves relative to the second threaded rod. This causes the first and second threaded sleeves to move towards each other or away from each other. The first connecting rod rotates relative to the first threaded sleeve, and the second connecting rod rotates relative to the second threaded sleeve. This causes the third and fourth threaded rods to move relative to the corresponding first limiting slides, thereby adjusting the height of the plastic film roller.

[0015] Secondly, it allows for easy replacement of plastic film rollers of different widths. By rotating the third threaded rod, the third threaded rod drives the fourth threaded rod to rotate. Due to the limiting effect of the first and second connecting rods, the third threaded sleeve moves relative to the third threaded rod, and the fourth threaded sleeve moves relative to the fourth threaded rod. This causes the third and fourth threaded sleeves to move towards each other or away from each other, which in turn causes the frustum-shaped clamping block to move towards each other or away from each other, allowing the frustum-shaped clamping block to clamp or release the plastic film roller, thus facilitating the replacement of plastic film rollers of different widths.

[0016] Thirdly, by moving the third and fourth threaded sleeves toward each other or away from each other, the two film-covering wheels and the two soil-covering discs are moved toward each other or away from each other, adjusting the distance between the film-covering wheels and the distance between the soil-covering discs. By rotating the fifth threaded rod, the height of the film-covering wheels can be adjusted. By loosening the fixing bolts, the L-shaped rod can be pulled to slide relative to the third limiting sleeve, thereby adjusting the height of the soil-covering discs. This allows the film-covering wheels to press down on both sides of the film during film covering, and then the soil-covering wheels press the soil onto both sides of the film, laying the film flat and firmly.

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0025] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] Example, refer to Figure 1-4 A film covering device for improving the germination rate of Angelica sinensis seeds includes a support 1. A connecting frame 30 is rotatably connected to the front end of the support 1. A first limiting slide 8 is provided on the front side of both the left and right ends of the support 1. A first threaded rod 2 is rotatably connected to the front side of the upper right side inside the support 1. A second threaded rod 5 with the opposite thread and rotatably connected to the support 1 is horizontally provided on the left end of the first threaded rod 2. A first threaded sleeve 3 is threadedly connected to the outer side of the first threaded rod 2. A second threaded sleeve 6 is threadedly connected to the outer side of the second threaded rod 5, which can easily drive the first threaded sleeve 3 and the second threaded sleeve 6 to move towards each other or away from each other.

[0027] Inside the bracket 1, below the first threaded rod 2, there is a horizontally arranged third threaded rod 9 that is slidably connected to the corresponding first limiting slide 8. At the left end of the third threaded rod 9, there is a horizontally arranged fourth threaded rod 11 that is threaded in the opposite direction and slidably connected to the corresponding first limiting slide 8. A third threaded sleeve 10 is threadedly connected to the outer side of the third threaded rod 9, and a fourth threaded sleeve 12 is threadedly connected to the outer side of the fourth threaded rod 11. This allows the third threaded sleeve 10 and the fourth threaded sleeve 12 to be easily moved toward each other or away from each other. A first handle 15 is provided at the right end of both the first threaded rod 2 and the third threaded rod 9.

[0028] The lower end of the first threaded sleeve 3 is rotatably connected to a first connecting rod 4, which is rotatably connected to the third threaded sleeve 10. The lower end of the second threaded sleeve 6 is rotatably connected to a second connecting rod 7, which is rotatably connected to the fourth threaded sleeve 12. The lower ends of the third threaded sleeve 10 and the fourth threaded sleeve 12 are both vertically provided with a first support rod 13. The lower end of each first support rod 13 is rotatably connected to a frustum-shaped clamping block 14, which is horizontally arranged and frustum-shaped, so as to easily clamp plastic film rollers 31 of different thicknesses. A plastic film roller 31 is detachably provided between the two frustum-shaped clamping blocks 14, so as to easily replace the plastic film roller 31 of different widths as needed, and at the same time, it is easy to adjust the height of the plastic film roller 31.

[0029] Each first support rod 13 has a horizontally arranged second support rod 16 at its rear end. Each second support rod 16 has a first limiting sleeve 17 at its rear end. Each first limiting sleeve 17 has a vertically arranged third support rod 18 slidably connected inside. Each third support rod 18 has a coating wheel 19 rotatably connected to its lower end. The bracket 1 has an adjustment device for adjusting the height of the coating wheel 19, including a second limiting slot opened on the rear side of both the left and right ends of the bracket 1. The bracket 1 has a horizontally arranged second limiting slot slidably connected inside, which is connected to each first support rod 13. The fourth support rod 22 is slidably connected to the second limiting port. The upper end of each third is provided with a second limiting sleeve 20 that is slidably connected to the fourth support rod 22. The rear side of the upper end of the bracket 1 is threaded with a fifth threaded rod 23 that is vertically arranged and rotatably connected to the fourth support rod 22. The upper end of the fifth threaded rod 23 is provided with a second handle 24, which can conveniently adjust the spacing between the film-coating rollers 19 and the height between the film-coating rollers 19, so that the film-coating rollers 19 can press the two sides of the film during the film-coating process and lay the film flat.

[0030] Each third support rod 18 has a soil covering device at its lower end, including a fifth support rod 25 horizontally positioned at the lower end of each support rod. Each fifth support rod 25 has a third limiting sleeve 26 at its rear end. Each third limiting sleeve 26 has a vertically positioned L-shaped rod 27 slidably connected inside. Each L-shaped rod 27 has a soil covering disc 28 at its lower end. Each third limiting sleeve 26 has a fixing bolt 29 threadedly connected to its outer side for fixing the corresponding L-shaped rod 27. This allows for easy adjustment of the spacing between the soil covering discs 28 and the height of the soil covering discs 28, enabling the soil covering discs 28 to carry soil to cover both sides of the film, thereby ensuring the film is laid securely.

[0031] Usage: When using, first determine the width of the film to be laid, select a plastic film roller 31 of appropriate width, and then install the plastic film roller 31. By rotating the corresponding first handle 15, the third threaded rod 9 is driven to rotate relative to the corresponding first limiting slide 8. Due to the limiting effect of the first connecting rod 4, the third threaded rod 9 will rotate relative to the third threaded sleeve 10, driving the third threaded sleeve 10 to move relative to the third threaded rod 9. At the same time, the third threaded rod 9 drives the fourth threaded rod 11 to rotate. Due to the limiting effect of the second connecting rod 7, the fourth threaded rod 11 drives the fourth threaded sleeve 12 to move relative to it, thereby causing the third threaded sleeve 10 and the fourth threaded sleeve 12 to move towards each other. Through the first support rod 13, the frustum-shaped clamping block 14 is driven to move closer to each other, so that the frustum-shaped clamping block 14 clamps the plastic film roller 31.

[0032] The movement of the first support rod 13 will drive the movement of the second support rod 16, which in turn drives the movement of the third support rod 18. The third support rod 18 will drive the second limiting sleeve 20 to move relative to the fourth support rod 22, thereby adjusting the distance between the film-covering wheels 19 to be equal to that between the plastic film rollers 31. By rotating the second handle 24, the fifth threaded rod 23 will rotate, and the fifth threaded rod 23 will move up and down relative to the bracket 1, thereby driving the fourth support rod 22 to move in the second limiting slide 21, which will drive the third support rod 18 to slide relative to the first limiting sleeve 17, adjusting the height of the film-covering wheels 19. The third support rod 18 will drive the movement of the fifth support rod 25, which can adjust the spacing between the soil-covering discs 28. Pulling the L-shaped rod 27 to slide relative to the third limiting sleeve 26 and fixing the L-shaped rod 27 with the fixing bolt 29 can adjust the height of the soil-covering discs 28.

[0033] Rotating the first handle 15 causes the first threaded rod 2 to rotate, which in turn causes the first threaded sleeve 3 to move relative to it. The first threaded rod 2 then causes the second threaded rod 5 to rotate, which in turn causes the first threaded sleeve 3 to move relative to it. This causes the first threaded sleeve 3 and the second threaded sleeve 6 to move towards or away from each other. The first threaded sleeve 3 causes the first connecting rod 4 to rotate relative to it, and the second threaded sleeve 6 causes the first connecting rod 4 to rotate relative to it. Through the first connecting rod 4 and the second connecting rod 7, the third threaded sleeve 10 and... The fourth threaded sleeve 12 moves up and down, thereby driving the third threaded rod 9 and the fourth threaded rod 11 to slide in the corresponding first limit sliding mouth 8, adjusting the height of the plastic film roller 31. When laying the film, the bracket 1 is connected to the tractor through the connecting frame 30, driving the bracket 1 to move. By pulling the plastic film roller 31, the plastic film roller 31 drives the frustum-shaped clamping block 14 to rotate, taking the film off the plastic film roller 31 for laying. The film covering wheel 19 rotates to press down on both sides of the film, and then the soil covering plate 28 covers both sides of the film with soil, laying the film flat.

[0034] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
