Description

Technical Field

[0001] This utility model relates to the field of vegetable planting technology, specifically a seedling tray extraction mechanism. Background Technology

[0002] Transplanting seedlings from seed trays is a major planting method in vegetable production. After the seeds are sown in seed trays, the seedlings emerge in the trays and grow into seedlings. Once the seedlings have grown, they need to be transplanted into cultivation trays to continue growing.

[0003] Currently, all existing seedling tray extraction mechanisms are used on transplanting machines. When planting seedlings in small batches from seed trays into planting pots, the seedlings are usually pulled out of the seed trays manually for transplanting. This method reduces the substrate around the seedling roots, resulting in insufficient nutrients and water for the seedlings after transplanting, which hinders growth and reduces the survival rate. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a seedling tray transplanting mechanism that provides sufficient substrate during the transplanting process, thereby improving the survival rate of seedlings.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a seedling tray retrieval mechanism, comprising a base plate, a movable rod movably mounted on the upper end of the base plate through a through hole, four pull rods hinged in a circular array on the lower end of the base plate, the other end of the pull rods being hinged to a clamping rod, a clamping plate being mounted on the lower end of each of the four clamping rods, a pressure plate being movably mounted on the upper part of the base plate, and a linkage component being installed between the lower end of the pressure plate and the upper end of the movable rod.

[0006] Preferably, a retaining ring is installed on the surface of the moving rod between the pulling rod and the base plate, and a spring is installed on the surface of the moving rod between the retaining ring and the base plate.

[0007] Preferably, the linkage assembly includes a linkage plate, a fixed plate, and a pressure rod. The upper end of the moving rod is hinged to the linkage plate, and the upper end of the base plate on one side of the moving rod is mounted with the fixed plate. The upper end of the fixed plate is hinged to the middle of the linkage plate, and the other end of the linkage plate is hinged to the lower end of the pressure rod. The pressure rod is fixed on the pressure plate.

[0008] Preferably, guide rods are installed on both sides of the lower end of the pressure plate, and sleeves are installed on the upper end of the base plate below the guide rods, with the lower end of the guide rods located inside the sleeves.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. When using this application, the four clamping plates can clamp the roots and root substrate of the seedlings in the plug tray, with a large working area, avoiding the impact on the survival rate of transplanted seedlings due to insufficient root substrate.

[0011] 2. This application installs a fixing ring and a spring on the moving rod. When the four clamping plates move closer to each other, the spring is compressed and stores force. After no pressure is applied to the pressure plate, the spring returns to its original state and drives the four clamping plates to move away from each other, so that the seedling roots can be clamped directly in the next use.

[0016] 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.

[0017] like Figures 1 to 3 As shown, a seedling tray transplanting mechanism includes a base plate 1. A movable rod 2 is movably mounted on the upper end of the base plate 1 through a through hole. The movable rod 2 can move up and down on the base plate 1. Four pull rods 5 are hinged in a circular array at the lower end of the base plate 1. The other end of each pull rod 5 is hinged to a clamping rod 3. Each of the four clamping rods 3 has a clamping plate 4 mounted on its lower end. The clamping rods 3 can move the clamping plates 4 closer to the movable rod 2, thus clamping the seedlings and substrate inside the seed tray. When the movable rod 2 moves upward, it pulls the clamping rods 3 through the pull rods 5, causing the four clamping plates 4 to move closer together, thereby clamping the substrate around the roots of the seedlings and preventing the substrate from falling off the seedling roots. A pressure plate 7 is movably mounted above the base plate 1. A linkage component 8 is installed between the lower end of the pressure plate 7 and the upper end of the movable rod 2. The pressure plate 7 moves the movable rod 2 upward through the linkage component 8, facilitating single-handed transplanting of seedlings.

[0018] like Figure 2As shown, specifically, a fixing ring 9 is installed on the surface of the moving rod 2 between the pulling rod 5 and the base plate 1, and a spring spring 10 is installed on the surface of the moving rod 2 between the fixing ring 9 and the base plate 1. The spring spring 10 generates elastic force, which causes the fixing ring 9 to move away from the base plate 1, so that the four clamping plates 4 are in a position away from each other, realizing the reset of the clamping plates 4 after use, and facilitating direct clamping in subsequent use.

[0019] Furthermore, the linkage assembly 8 includes a linkage plate 801, a fixed plate 802, and a pressure rod 803. The upper end of the moving rod 2 is hinged to the linkage plate 801, and the upper end of the base plate 1 on one side of the moving rod 2 is fitted with the fixed plate 802. The upper end of the fixed plate 802 is hinged to the middle of the linkage plate 801, and the other end of the linkage plate 801 is hinged to the lower end of the pressure rod 803. The pressure rod 803 is fixed on the pressure plate 7. By pressing the pressure plate 7, the pressure rod 803 is moved downward. The fixed plate 802 and the linkage plate 801 form a seesaw structure. The downward movement of the pressure rod 803 causes one end of the linkage plate 801 to descend, and the other end of the linkage plate 801 to rise, causing the moving rod 2 to move upward, thereby realizing the mutual approach of the four clamping plates 4.

[0020] Furthermore, the pull rods 5 are distributed in a circular array at equal intervals on the surface of the moving rod 2. When the moving rod 2 moves upward under the action of the pull rods 5, it can drive the four clamping plates 4 to move closer to each other.

[0021] Furthermore, guide rods 11 are installed on both sides of the lower end of the pressure plate 7, and sleeves 6 are installed on the upper end of the base plate 1 below the guide rods 11. The lower end of the guide rods 11 is located inside the sleeves 6. When the pressure plate 7 moves downward, one end of the guide rods 11 moves inside the sleeves 6, which facilitates the vertical movement of the pressure plate 7 and guides the movement of the pressure plate 7.

[0022] The method of use in this embodiment is as follows: During use, the transplanter holds the base plate 1, with the pressure plate 7 in the palm of the transplanter's hand. Then, the four clamping plates 4 are inserted into the seedling tray, so that the seedling is located between the four clamping plates 4. The four clamping plates 4 clamp the roots of the seedling and the substrate outside the roots. Then, pressure is applied by the palm to bring the base plate 1 and the pressure plate 7 closer together. During this process, the pressure plate 7 presses one end of the linkage plate 801 through the pressure rod 803. Under the action of the fixed plate 802, the other end of the linkage plate 801 drives the moving rod 2 to rise. The moving rod 2 pulls... The moving rod 5 drives the four clamping rods 3 to move closer together, and the clamping plates 4 at the lower ends of the four clamping rods 3 move closer together, thus clamping the seedlings and root substrate. At the same time, the moving rod 2 compresses the elastic spring 10 through the fixing ring 9 and then applies upward tension to remove the seedling roots and root substrate from the seedling tray. Then, the four clamping plates 4 are inserted into the cultivation pot, releasing the pressure on the pressure plate 7. Under the action of the elastic spring 10, the four clamping plates 4 move away from each other, allowing the four clamping plates 4 to return to their original positions. When transplanting seedlings again, the above steps can be repeated.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
