Description

Technical Field

[0001] This utility model relates to the field of film covering device technology, and more specifically, to a film covering device for the seedling stage of Chinese medicinal materials. Background Technology

[0002] Mulching is an important technical measure in modern agriculture. Mulching can effectively increase soil temperature, creating a warm environment suitable for seed germination and seedling growth under the low temperatures of early spring, raising the temperature of the top 5 cm of soil by 3 to 6 degrees Celsius. Mulching has a good moisture retention effect, reducing soil moisture evaporation by more than 60% and maintaining stable soil moisture. Mulching can suppress weed growth and reduce competition for nutrients and water by weeds. In addition, mulching can prevent soil compaction caused by rainwater erosion, improve soil structure, and promote root development. Mulching can reduce the damage to seedlings caused by wind and low temperatures, improve seedling survival rate and seedling quality, shorten the seedling cycle, and lay a good foundation for later crop growth.

[0003] During the cultivation of Chinese medicinal herbs, operators often use corresponding mulching devices to cover the seedlings during the seedling stage. While existing mulching devices have basic mulching functions, they typically only accommodate mulching rollers of the same size. Different types of Chinese medicinal herbs require different types and sizes of mulch. For example, licorice requires large-sized mulch to cover the entire bed to increase soil temperature, while ginseng prefers small to medium-sized mulch to avoid excessive heating. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a film covering device for the seedling stage of Chinese medicinal materials, which has the advantage of wide applicability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a film covering device for seedling cultivation of Chinese medicinal herbs, comprising a fixed frame, an installation frame fixedly connected to the top of the fixed frame, a rectangular plate fixedly connected to the back of the installation frame, a fine-threaded rod movably sleeved on the inner surface of the rectangular plate, the bottom end of the fine-threaded rod penetrating the rectangular plate and extending into the interior of the rectangular plate and threadedly sleeved with a moving block, the back of the moving block being movably connected to the inner surface of the installation frame, inclined rods hinged to both sides of the moving block, a connecting rod hinged to the other end of the inclined rod, fixed sleeves fixedly connected to both sides of the back of the installation frame, the inner surface of the fixed sleeves being movably sleeved with the outer surface of the connecting rod, a telescopic rod fixedly connected to the inner side of the connecting rod, the other end of the telescopic rod penetrating the installation frame and extending into the inner cavity of the installation frame and fixedly connected to an installation seat, and a film covering roller movably sleeved between the installation seats.

[0006] As a preferred embodiment of this utility model, an installation roller is fixedly connected to the right side of the inner cavity of the fixed frame, and a vertical rod is movably sleeved on the left side of the inner cavity of the fixed frame. The bottom end of the vertical rod passes through the fixed frame and extends into the interior of the fixed frame, and a gear is fixedly sleeved thereon. A handle is fixedly sleeved on the top of the vertical rod. Toothed plates are meshed on both the front and rear sides of the outer surface of the gear, and a sliding frame is fixedly connected to the other end of the toothed plate.

[0007] As a preferred embodiment of this utility model, the sliding frame is fixedly connected to both the front and rear sides with limiting blocks, the outer surfaces of the sliding frame and the limiting blocks are movably connected to the inner surface of the fixed frame, and a handle is fixedly connected to the top of the fixed frame.

[0008] As a preferred embodiment of this utility model, four rollers are movably mounted on the outer side of the sliding frame, and all four rollers are of the same size.

[0009] As a preferred embodiment of this utility model, a vertical plate is fixedly connected to the bottom of the inner cavity of the fixing frame, and a movable rod is movably sleeved inside the vertical plate. The right side of the movable rod passes through the vertical plate and extends to the outside of the vertical plate and is fixedly connected to a locking block. The right side of the locking block is meshed with the left side of the gear.

[0010] As a preferred embodiment of this utility model, a toggle block is fixedly connected to the left side of the movable rod, the outer surface of the toggle block is movably connected to the inner surface of the fixed frame, and a baffle is fixedly connected to the left side of the toggle block, the bottom of the baffle is movably connected to the top of the fixed frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a diagonal rod, a connecting rod, a fixed sleeve, a telescopic rod, and a mounting base, allows the moving block to move vertically downward under the limiting action of the mounting frame when the fine-threaded rod is rotated. This causes the two diagonal rods to move, which in turn causes the two connecting rods to drive the two telescopic rods and the two mounting bases to move horizontally in opposite directions under the limiting action of the fixed sleeve. Ultimately, this achieves the function of adjusting the distance between the two mounting bases, making it convenient for operators to install film-covering rollers of different sizes, thereby adapting to complex seedling cultivation modes and improving the flexibility of use.

This utility model, by setting a handle, gear, toothed plate, sliding frame, and limiting block, first pulls the actuating block, causing the actuating block to drive the movable rod and the locking block to move horizontally to the left, and causing the locking block to disengage from the outer surface of the gear, thereby releasing the fixing effect on the gear and the vertical rod. Then, by rotating the handle, the vertical rod and gear rotate together, and the two toothed plates drive the two sliding frames and the limiting block to move horizontally in opposite directions under the limiting action of the fixed frame. This causes the two sliding frames to extend outward along the inner surface of the fixed frame, realizing the function of adjusting the distance between the rollers, thereby adapting to different ridge widths or bed sizes and matching different types of Chinese medicinal materials planting patterns.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5As shown, this utility model provides a film covering device for seedling cultivation of Chinese medicinal materials, including a fixed frame 1, an installation frame 2 fixedly connected to the top of the fixed frame 1, a rectangular plate 3 fixedly connected to the back of the installation frame 2, a fine-threaded rod 4 movably sleeved on the inner surface of the rectangular plate 3, the bottom end of the fine-threaded rod 4 penetrating through the rectangular plate 3 and extending into the interior of the rectangular plate 3 and threadedly sleeved with a moving block 5, the back of the moving block 5 movably connected to the inner surface of the installation frame 2, and inclined rods 6 hinged to both sides of the moving block 5, the other end of the inclined rods 6 hinged to a connecting rod 7, fixed sleeves 8 fixedly connected to both sides of the back of the installation frame 2, the inner surface of the fixed sleeves 8 movably sleeved with the outer surface of the connecting rod 7, a telescopic rod 9 fixedly connected to the inner side of the connecting rod 7, the other end of the telescopic rod 9 penetrating through the installation frame 2 and extending into the inner cavity of the installation frame 2 and fixedly connected to an installation seat 10, and a film covering roller 11 movably sleeved between the installation seats 10.

[0023] When the fine thread rod 4 is rotated, the moving block 5 will move vertically downward under the limiting action of the mounting bracket 2, and the two inclined rods 6 will move, thereby causing the two connecting rods 7 to drive the two telescopic rods 9 and the two mounting seats 10 to move horizontally in opposite directions under the limiting action of the fixed sleeve 8.

[0024] The mounting roller 12 is fixedly connected to the right side of the inner cavity of the fixed frame 1, and the vertical rod 13 is movably sleeved on the left side of the inner cavity of the fixed frame 1. The bottom end of the vertical rod 13 passes through the fixed frame 1 and extends into the interior of the fixed frame 1 and is fixedly sleeved with a gear 15. The top of the vertical rod 13 is fixedly sleeved with a handle 14. The front and rear sides of the outer surface of the gear 15 are meshed with toothed plates 16, and the other end of the toothed plates 16 is fixedly connected with a sliding frame 17.

[0025] When the handle 14 is rotated, the vertical rod 13 and the gear 15 will rotate synchronously, and the two toothed plates 16 will move in opposite directions, thereby driving the two sliding frames 17 to move synchronously.

[0026] The sliding frame 17 has limit blocks 18 fixedly connected to both the front and rear sides. The outer surfaces of the sliding frame 17 and the limit blocks 18 are movably connected to the inner surface of the fixed frame 1. The top of the fixed frame 1 is fixedly connected to a handle 20.

[0027] Due to the travel limiting function of the limiting block 18, the sliding frame 17 is prevented from detaching from the inner surface of the fixed frame 1 during the process of extending outward from inside the fixed frame 1.

[0028] The sliding frame 17 has four rollers 19 movably mounted on its outer side. All four rollers 19 are the same size.

[0029] The operator can move the entire device by pushing the four rollers 19 to roll by holding the lever 20.

[0030] The bottom of the inner cavity of the fixed frame 1 is fixedly connected to a vertical plate 21. A movable rod 22 is movably sleeved inside the vertical plate 21. The right side of the movable rod 22 passes through the vertical plate 21 and extends to the outside of the vertical plate 21 and is fixedly connected to a locking block 26. The right side of the locking block 26 is engaged with the left side of the gear 15.

[0031] When the movable rod 22 drives the locking block 26 to move to the left under the limiting action of the vertical plate 21, and causes the locking block 26 to disengage from the outer surface of the gear 15, the fixing effect on the gear 15 will be released.

[0032] Among them, a toggle block 23 is fixedly connected to the left side of the movable rod 22. The outer surface of the toggle block 23 is movably connected to the inner surface of the fixed frame 1. A baffle 24 is fixedly connected to the left side of the toggle block 23. The bottom of the baffle 24 is movably connected to the top of the fixed frame 1.

[0033] The design of the baffle 24 achieves a sealing effect on the top of the inner cavity of the fixing frame 1, preventing external soil or small insects from entering the interior of the fixing frame 1 and getting stuck on the gear 15 and the toothed plate 16.

[0034] Among them, a spring 25 is movably sleeved on the outer surface of the movable rod 22. The left end of the spring 25 is fixedly connected to the right side of the toggle block 23, and the right end of the spring 25 is fixedly connected to the left side of the vertical plate 21.

[0035] Due to the elastic force of spring 25, the locking block 26 has a good reset effect during subsequent movement.

[0036] Working principle and usage process of this utility model:

[0037] During the mulching process of Chinese medicinal herbs, when a larger mulch is required, rotating the fine-threaded rod 4 causes the moving block 5 to move vertically downward under the limiting action of the mounting frame 2, and causes the two inclined rods 6 to move. This causes the two connecting rods 7 to drive the two telescopic rods 9 and the two mounting seats 10 to move horizontally in opposite directions under the limiting action of the fixed sleeve 8. Ultimately, this achieves the function of adjusting the distance between the two mounting seats 10, making it convenient for operators to install mulch rollers 11 of different sizes, thereby adapting to complex seedling cultivation modes and improving the flexibility of use.

[0038] Different types of Chinese medicinal herbs have different planting patterns, such as common ridge planting, flat beds, and seed trays, each with different ridge widths. To prevent the rollers 19 from pressing on the seedlings during the subsequent mulching process, when adjusting the lateral width of the four rollers 19, it is necessary to first pull the actuating block 23, causing the actuating block 23 to drive the vertical plate 21 and the locking block 26 to move horizontally to the left, and causing the locking block 26 to disengage from the outer surface of the gear 15, thereby releasing the fixing effect on the gear 15 and the vertical rod 13. Then, by turning the handle 14, the vertical rod 13 and the gear 15 are rotated together, and the two toothed plates 16 respectively drive the two sliding frames 17 and the limiting block 18 to move horizontally in opposite directions under the limiting action of the fixed frame 1. This causes the two sliding frames 17 to extend outward along the inner surface of the fixed frame 1, realizing the function of adjusting the spacing of the rollers 19, thereby adapting to different ridge widths or bed sizes and matching different types of Chinese medicinal herbs.
