Description

Technical Field

[0001] This utility model relates to the field of greenhouse seedling transplanting technology, and in particular to an auxiliary tool for greenhouse seedling transplanting. Background Technology

[0002] Transplanting seedlings is a common agricultural operation in greenhouse cultivation, which is directly related to the growth and development of crops and their final yield. In order to improve the efficiency and quality of transplanting, transplanting auxiliary tools have emerged.

[0003] Currently used transplanting aids include ring-shaped opening transplanters and duckbill transplanters. However, each has its own advantages and disadvantages. For example, with ring-shaped opening transplanters, the seedling is wrapped into the ring structure from the side of the opening before transplanting. This process does not damage the seedling's leaves and can improve the seedling's survival rate. However, when the seedling is removed along with the soil, the soil is prone to spilling out from the opening, which can damage the soil around the roots. Duckbill transplanters, on the other hand, can completely remove the roots and the surrounding soil, solving the problem of soil spillage with ring-shaped opening transplanters. However, before transplanting the seedling, the seedling is transplanted by dropping it from above around the seedling. This process can easily damage the seedling's leaves and reduce the seedling's survival rate.

[0004] Therefore, in response to the above problems, we propose a greenhouse seedling transplanting auxiliary tool to solve these problems. Utility Model Content

[0005] This invention provides a greenhouse seedling transplanting auxiliary tool to solve the problems in the prior art.

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] A greenhouse seedling transplanting aid includes a transplanting ring with an opening on its side. A connecting rod is mounted on the transplanting ring, and an operating rod is mounted on the connecting rod. A first movable rod is slidably connected to the operating rod. A soil-pushing ring, which can slide axially along the inner wall of the transplanting ring, is located at the bottom of the first movable rod. A second movable rod, parallel to the connecting rod, is slidably connected to the operating rod. An arc-shaped plate, with its convex surface facing inwards, is located at the bottom of the second movable rod to seal the opening of the transplanting ring. When the second movable rod moves the arc-shaped plate downwards, it compresses the soil within the transplanting ring, achieving a tight bond between the soil particles.

[0008] Preferably, the operating lever is provided with a locking assembly for fixing the second movable lever. The locking assembly includes a toothed rack slidably connected inside the operating lever and a plurality of slots equidistantly opened on the second movable lever. A spring is connected between the toothed rack and the operating lever.

[0009] Preferably, a second spring connects the operating lever and the second movable lever.

[0010] Preferably, the operating lever is connected via a fixing rod to a scraping component for scraping soil off the surface of the arc-shaped plate.

[0011] Preferably, both the transplanting ring and the bottom of the arc-shaped plate are provided with an insertion part.

[0012] Preferably, both the arc-shaped plate and the transplanting ring are equipped with stepping plates.

[0013] The beneficial effects of this utility model are as follows: before the seedling is removed from the soil by inserting the transplanting ring into the soil, the second movable rod drives the arc plate to descend and seal the opening on the transplanting ring. At the same time, the arc plate applies a squeezing force to the soil inside the transplanting ring, so as to achieve a tight bond between the soil inside the transplanting ring, which can prevent the soil from falling out from the opening on the transplanting ring and improve the stability between the soils.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0022] Reference Figure 1 The provided schematic diagram of the prior art structure shows a greenhouse seedling transplanting auxiliary tool, including a transplanting ring 1 with a side opening, a connecting rod 2 on the transplanting ring 1, and an operating rod 3 on the connecting rod 2. In use, the seedling is approached from the side opening of the transplanting ring 1, and the seedling is wrapped in it to position it, which can prevent damage to the seedling's leaves. Then, the operating rod 3 is pressed to apply force to the connecting rod 2 and the transplanting ring 1, inserting the transplanting ring 1 into the soil. The operating rod 3 is rotated to loosen the soil inside the transplanting ring 1. Then, the transplanting ring 1 is pulled out. At this time, the transplanting ring 1 moves the seedling and the soil around the roots out. In order to facilitate the replanting of the transplanted seedling in a suitable position, a soil-pushing ring 5 is provided at the bottom of the first movable rod 4, which can slide axially along the inner wall of the transplanting ring 1. Pushing the first movable rod 4 moves the soil-pushing ring 5 to push the soil, thereby moving the seedling and the surrounding root soil out of the transplanting ring 1.

[0023] However, after the seedlings and their root soil are removed, the soil easily spills out from the opening on the side of the transplanting ring 1, and the falling root soil may affect the survival of the seedlings. To solve this problem, such as Figures 2-4 A second movable rod 6, parallel to the connecting rod 2, is slidably connected to the operating rod 3. The bottom of the second movable rod 6 is provided with an arc-shaped plate 7. After the transplanting ring 1 is inserted into the soil, the second movable rod 6 is pushed to make the arc-shaped plate 7 descend. The descending arc-shaped plate 7 enters the opening on the transplanting ring 1 and seals it. At the same time, since the curved surface of the arc-shaped plate 7 faces the inside of the transplanting ring 1, when the arc-shaped plate 7 seals the opening on the transplanting ring 1, the arc-shaped plate 7 generates an inward squeezing force on the soil inside the transplanting ring 1, making the soil particles more tightly bound, increasing the stability of the soil inside the transplanting ring 1, and reducing the problem of seedling survival affected by the loss of soil around the seedling roots.

[0024] Reference Figure 4 , Figure 5As shown, furthermore, to prevent the arc-shaped plate 7 from affecting the seedlings' movement from the side of the transplanting ring 1 into the inside of the transplanting ring 1 during transplanting, a locking assembly for fixing the second movable rod 6 is provided on the operating rod 3. The locking assembly includes a toothed rack 81 slidably connected inside the operating rod 3 and multiple slots 82 equidistantly opened on the second movable rod 6. A spring 9 connects the toothed rack 81 and the operating rod 3. The toothed rack 81 is provided with multiple teeth with triangular cross-sections, and the inclined surface of the slots 82 is also triangular. Therefore, the toothed rack 81 can be locked in the slots 82. When the toothed rack 81 is locked in the slots 82, the inclined surface of the slots 82 is opposite to the inclined surface of the toothed rack 81, and under the elastic action of the spring 9, it abuts against the toothed rack 81, thus fixing it in place. The arc plate 7 is fixed in the slot 82. When the arc plate 7 needs to be lowered to seal the opening on the seedling ring 1, the second movable rod 6 is pressed. At this time, the inclined surface in the slot 82 abuts against the inclined surface on the toothed rack 81, and the toothed rack 81 is continuously squeezed, causing the spring 9 to deform. When the force on the second movable rod 6 is stopped, the toothed rack 81 automatically engages in the slot 82 to fix the position of the arc plate 7. When the arc plate 7 is moved up, the toothed rack 81 is pulled out of the slot 82, releasing the limit on the second movable rod 6. The second movable rod 6 is pulled up to the appropriate position. After the toothed rack 81 is released, under the elastic action of the spring 9, the toothed rack 81 is then engaged in the slot 82 to fix the second movable rod 6.

[0025] Reference Figures 2-4 As shown, further, in order to release the limit of the second movable rod 6 and drive the arc plate 7 to move upward, a second spring 10 is connected between the operating rod 3 and the second movable rod 6. In the initial state, the second spring 10, under its elastic action, makes the arc plate 7 close to the position of the operating rod 3. At this time, it is far from the opening of the seedling transplanting ring 1, so as to prevent the arc plate 7 from falling and affecting the positioning of the seedling. When it is necessary to seal the opening of the seedling transplanting ring 1, the second movable rod 6 falls and the second spring 10 is squeezed and deformed. When it is necessary to move the arc plate 7 upward, the second spring 10 returns to its deformation, and the arc plate 7 can move upward automatically.

[0026] Reference Figures 2-4 As shown, furthermore, in order to scrape the soil off the surface of the curved plate 7, the operating rod 3 is connected to a scraper 11 for scraping the soil off the surface of the curved plate 7 via a fixing rod 14. The inside of the scraper 11 can be adapted to the surface of the curved plate 7. When the curved plate 7 moves upward, it will pass through the inside of the scraper 11, and the inner wall of the scraper 11 will contact the surface of the curved plate 7 and scrape off the soil on the surface of the curved plate 7, preventing the surface of the curved plate 7 from sticking with soil during continuous use and affecting its use.

[0027] Reference Figures 1-4As shown, furthermore, in order to facilitate insertion into the soil, both the transplanting ring 1 and the arc-shaped plate 7 are provided with an insertion part 12 at their bottom. The insertion part 12 can be serrated, blade-shaped, etc. The soil in the greenhouse may contain some soil clods of different sizes, which will increase the difficulty of inserting the transplanting ring 1 and the arc-shaped plate 7. The special shape of the insertion part 12 can effectively break these soil clods, making it easier for the transplanting ring 1 and the arc-shaped plate 7 to cut into the soil, reducing the external force required for insertion, making it easier for operators to use, and reducing labor intensity.

[0028] Reference Figures 1-4 As shown, furthermore, to facilitate the application of force, both the curved plate 7 and the transplanting ring 1 are equipped with foot plates 13. By placing the foot on the foot plate 13 to apply force, the force applied by the foot can be transmitted more directly and effectively to the transplanting ring 1 and the curved plate 7, making them easier to insert into deeper soil. In some greenhouse environments with high soil compaction, sufficient insertion depth is crucial for completely wrapping the seedling roots. The additional force provided by the foot plate 13 can ensure that the transplanting ring 1 and the curved plate 7 can smoothly penetrate the harder soil layer and reach the appropriate depth, thus better realizing the transplanting function. At the same time, the support and force applied by the foot can also increase the stability of the tool during the insertion process, reduce shaking and deviation, and ensure the accuracy of the operation. In addition, an opening is provided on the scraper 11 for the foot plate 13 on the curved plate 7 to pass through, preventing interference with the normal scraping process of the scraper 11 on the surface of the curved plate 7.
