DETAILED DESCRIPTION

[0035] The present invention will be described in detail below with reference to the accompanying drawings.

[0036] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] Example 1

[0038] like Figure 1-2 As shown, a mechanical device for automatic seedling removal includes a support transmission system and a seedling removal system. The support transmission system includes four supporting legs arranged in a rectangular shape, each supporting leg includes a fixing part 1, a sliding part 2 and a prime mover 3, wherein the fixing part 1 is fixedly connected to the ground or other equipment, the sliding part 2 is embedded in the groove of the fixing part 1, and can slide up and down along the fixing part 1; the sliding part 2 is also provided with a groove, and the prime mover 3 is slidably connected in the groove of the sliding part 2, and the prime mover 3 can be powered by an external power to perform up and down reciprocating motion.

[0039] A rubber member 6 is provided between the prime mover 3 and the sliding member 2. When the prime mover 3 contacts the rubber member 6, the friction between them is large enough to enable the prime mover 3 to drive the sliding member 2 to slide upward or downward. At the same time, stop blocks are provided at the upper and lower ends of the fixed member 1 for blocking the sliding member 2. When the sliding member 2 contacts the stop blocks, the stop blocks can prevent the sliding member 2 from sliding further. At this time, the prime mover 3 can overcome the friction between it and the rubber member 6 and continue to move upward or downward relative to the sliding member 2. Furthermore, baffles can be provided at the upper and lower ends of the sliding member 2 to prevent the prime mover 3 from sliding out of the groove of the sliding member 2.

[0040] like Figure 3-6 As shown, the seedling taking system includes several seedling taking grooves 7, each of which is surrounded by two horizontal inclined plates 8 and two vertical inclined plates 9. The horizontal inclined plates 8 and the vertical inclined plates 9 are inclined inwardly, so that the upper end opening of the seedling taking groove 7 is large and the lower end opening is small; the two horizontal inclined plates 8 are respectively fixedly connected to different first horizontal rods 10, and the two vertical inclined plates 9 are respectively fixedly connected to different second horizontal rods 11. In this embodiment, Figure 4 The first horizontal rod 10 and the second horizontal rod 11 are parallel to each other, and the horizontal inclined plate 8 on the left side is fixedly connected to the first horizontal rod 10 extending to the right, and the horizontal inclined plate 8 on the right side is fixedly connected to the first horizontal rod 10 extending to the left, so that when the two first horizontal rods 10 move in opposite directions in the longitudinal direction, the two horizontal inclined plates 8 on the same seedling trough 7 can be driven to move closer or farther away; similarly, when the two second horizontal rods 11 move toward or in opposite directions in the transverse direction, the two longitudinal inclined plates 9 on the same seedling trough 7 can be driven to move closer or farther away to realize the opening and closing of the seedling trough 7.

[0041] Furthermore, the seedling troughs 7 can be arranged in multiple columns and rows by connecting multiple horizontal inclined plates 8 or vertical inclined plates 9 to the first horizontal rod 10 and the second horizontal rod 11, and matching the horizontal inclined plates 8 and the vertical inclined plates 9 to form multiple seedling troughs 7, thereby realizing a multi-row arrangement of the seedling troughs 7; and multiple first horizontal rods 10 and second horizontal rods 11 can also be provided to realize a multi-column arrangement of the seedling troughs 7. In this embodiment, the number of columns of the seedling troughs 7 is 3. The multi-column arrangement can increase the number of the seedling troughs 7 and shorten the longitudinal length of the device.

[0042] The driving member 3 is connected to the first horizontal rod 10 or the second horizontal rod 11 through a steering device. In a preferred embodiment, the upper end of the support foot is fixedly connected to a horizontal support plate 14, which is fixedly connected to the sliding member 2 and can move upward or downward with the sliding member 2. At the same time, the horizontal support plate 14 can be set as a two-layer structure, on which the first horizontal rod 10 and the second horizontal rod 11 are placed respectively to avoid mutual obstruction between the first horizontal rod 10 and the second horizontal rod 11; the steering device includes a connecting rod 12 and a vertical limiter 13, wherein the connecting rod 12 can be a straight rod, one end of which is hinged to the driving member 3, and the other end is hinged to the first horizontal rod 10 or the second horizontal rod 11, and the vertical limiter 13 It can be a block with a through groove at the lower end. The vertical limit member 13 is fixed on the horizontal support plate 14 near the support foot. The first horizontal rod 10 and the second horizontal rod 11 are hinged to the connecting rod 12 after passing through the through groove. The height of the through groove is equal to or slightly greater than the height of the first horizontal rod 10 and the second horizontal rod 11, so that the vertical limit member 13 can limit the vertical displacement of the first horizontal rod 10 and the second horizontal rod 11; when the prime mover 3 moves upward relative to the sliding member 2, the steering device can push the first horizontal rod 10 or the second horizontal rod 11 outward, and when the prime mover 3 moves downward relative to the sliding member 2, the steering device can pull the first horizontal rod 10 or the second horizontal rod 11 back inward.

[0043] The movement direction of the first horizontal rod 10 and the second horizontal rod 11 can be controlled by changing the position and direction of the supporting feet. In this embodiment, the two supporting feet located on the diagonal line form a group, and the two supporting feet in each group jointly control the first horizontal rod 10, or the second horizontal rod 11. When the prime mover 3 moves upward relative to the sliding member 2, the first horizontal rod 10 drives the horizontal inclined plate 8 to move closer, and the second horizontal rod 11 drives the vertical inclined plate 9 to move closer, and the seedling trough 7 is closed, so that the seedlings can be clamped; when the prime mover 3 moves downward relative to the sliding member 2, the first horizontal rod 10 drives the horizontal inclined plate 8 away, and the second horizontal rod 11 drives the vertical inclined plate 9 away, and the seedling trough 7 is opened, so that the seedlings can be put down.

[0044] Working principle of this device:

[0045] When the prime mover 3 is at the lowest point, driven by the external equipment, the prime mover 3 moves upward, and drives the sliding member 2 to move upward through the rubber member 6, and the horizontal support plate 14 moves upward synchronously with the seedling taking system. When the sliding member 2 abuts the stop block at the upper end, the sliding member 2, the horizontal support plate 14, and the seedling taking system stop moving upward, and the prime mover 3 continues to move upward relative to the sliding member 2, and pushes the first horizontal rod 10 and the second horizontal rod 11 outward through the steering device, thereby driving the horizontal inclined plates 8 and the vertical inclined plates 9 to move closer to each other, closing the seedling taking groove 7, and realizing seedling taking.

[0046] When the prime mover 3 is at the highest point, driven by the external equipment, the prime mover 3 moves downward, and the sliding member 2 also moves downward under the drive of its own weight and the rubber member 6. The horizontal support plate 14 moves downward synchronously with the seedling taking system. When the sliding member 2 abuts the stop block at the lower end, the sliding member 2, the horizontal support plate 14, and the seedling taking system stop moving downward, and the prime mover 3 continues to move downward relative to the sliding member 2, and pulls the first horizontal rod 10 and the second horizontal rod 11 inward through the steering device, thereby driving the horizontal inclined plates 8 and the vertical inclined plates 9 to separate from each other, and the seedling taking groove 7 opens to realize seedling release.

[0047] Therefore, the utility model forms a seedling trough 7 by using two horizontal inclined plates 8 and two vertical inclined plates 9 to enclose, and controls the movement of the horizontal inclined plates 8 or the vertical inclined plates 9 by the first horizontal rod 10 and the second horizontal rod 11, so as to realize the closing of the seedling trough 7 to clamp the seedlings, and the opening of the seedling trough 7 to put down the seedlings.

[0048] In addition, by providing a sliding member 2, the seedling removal system can move upward or downward as a whole. By providing a steering device, the prime mover 3 can push the first horizontal rod 10 and the second horizontal rod 11, thereby realizing the opening and closing of the seedling removal groove 7. Therefore, the entire device only needs to provide a single power for the sliding of the prime mover 3, which can effectively simplify the structure and facilitate use with other equipment.

[0049] In addition, by setting the rubber part 6 and the stop block, the device can first move upward or downward as a whole, and then open and close the seedling trough 7, which is convenient for clamping or placing seedlings at the specified position, improving the accuracy of seedling retrieval and placement, and realizing automatic seedling retrieval and placement.

[0050] The automatic seedling-taking mechanical device of the utility model has a simple overall structure, is easy to replace parts, has a low cost, can allow multiple seedling-taking slots 7 to work simultaneously, and has a high seedling-taking efficiency.

[0051] In the preferred solution, the horizontal support plate 14 is made of lightweight materials, such as plastic board, fiberboard, etc. The horizontal support plate 14 can also be hollowed out to further reduce its own weight and prevent the horizontal support plate 14 from breaking and collapsing due to being too heavy.

[0052] In the preferred solution, the driving member 3 includes an active block 4 and a passive block 5, wherein the active block 4 actively reciprocates up and down under the action of external power, and the passive block 5 is connected to the first horizontal rod 10 or the second horizontal rod 11 through a steering device, and the passive block 5 is located above the active block 4 and the rubber member 6. When the active block 4 overcomes the friction force of the rubber member 6 and moves upward, the active block 4 contacts the passive block 5 and thus pushes the passive block 5 to move upward. When the active block 4 moves downward relative to the sliding member 2, the passive block 5 can move downward under the action of gravity, but when it contacts the rubber member 6, the passive block 5 stops moving downward; the driving member 3 is divided into the active block 4 and the passive block 5, and the sliding range of the passive block 5 can be controlled by the rubber member 6, thereby controlling the movement distance of the horizontal inclined plate 8 and the vertical inclined plate 9 of the seedling trough 7, thereby avoiding damage to the seedling trough 7 during opening and closing.

[0053] Furthermore, the rubber members 6 are arranged continuously or at intervals along the vertical direction on the sliding member 2, and the spacing between two adjacent rubber members 6 is less than or equal to the vertical length of the active block 4, so that when the active block 4 slides relative to the sliding member 2, it contacts at least one rubber member 6 at every moment, thereby preventing the active block 4 from impacting the sliding member 2 after losing its constraint and causing damage to the sliding member 2.

[0054] In the preferred solution, a slide rail is provided between the prime mover 3 and the sliding member 2. The slide rail can be provided on both sides of the groove of the sliding member 2, which can reduce the resistance of the prime mover 3 when sliding and prevent the prime mover 3 from falling out of the groove of the sliding member 2.

[0055] Furthermore, anti-collision buffer layers can be set at the upper and lower ends of the fixing part 1 to reduce the impact force of the sliding part 2 on the fixing part 1. The anti-collision buffer layers can be made of foam or rubber material and pasted on the upper and lower ends of the fixing part 1.

[0056] In the preferred embodiment, the shapes of the horizontal inclined plates 8 and the vertical inclined plates 9 are both inverted trapezoids. The inverted trapezoids can reduce the side gap when the seedling trough 7 is closed, and improve the sealing effect of the seedling trough 7. At the same time, the inverted trapezoidal horizontal inclined plates 8 and the vertical inclined plates 9 also leave an opening at the bottom end of the seedling trough 7 to avoid cutting off the seedlings when the seedling trough 7 is closed.

[0057] Furthermore, the upper ends of the transverse inclined plate 8 and the longitudinal inclined plate 9 are connected to the first horizontal rod 10 or the second horizontal rod 11 to reduce the impact of the first horizontal rod 10 and the second horizontal rod 11 on the seedlings.

[0058] Example 2

[0059] Different from Example 1, this embodiment changes the relative positions of the first horizontal rod 10 and the second horizontal rod 11 so that when the prime mover 3 slides upward relative to the sliding member 2, the two horizontal inclined plates 8 and the two vertical inclined plates 9 of the same seedling trough 7 move away from each other, and the seedling trough 7 opens; when the prime mover 3 slides downward relative to the sliding member 2, the two horizontal inclined plates 8 and the two vertical inclined plates 9 of the same seedling trough 7 move closer to each other, and the seedling trough 7 closes, so that the device can clamp the seedlings downward and put the seedlings upward.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
