Description

Technical Field

[0001] This invention belongs to the field of facility agriculture engineering technology, and in particular relates to a seedling tray lifting device. Background Technology

[0002] Automated equipment such as tray grabbers and transplanters are increasingly widely used in agricultural planting. When a tray grabber grasps a seedling tray from upstream equipment, the coordination between the grabber's gripper and the tray's basket requires high precision. The upstream basket often has misalignment or installation errors, causing the grabber's gripper to miss the tray's edge, resulting in a failed grabbing. Transplanters also have the same problem with their seedling-grabbing mechanism. To solve these issues, a seedling tray lifting device is needed. This device lifts the seedling tray from the upstream basket, raising it to a certain height to eliminate misalignment and ensure the tray is within the grabber's gripping range, thus guaranteeing a higher success rate. Similarly, a lifting device can also lift the transplanter's seedling tray, ensuring the transplanter's seedling-grabbing mechanism accurately grasps the seedling clump. Therefore, developing a seedling tray lifting device that can be installed on both tray grabbers and transplanters is essential to improve their operational accuracy. Utility Model Content

[0003] The purpose of this utility model is to provide a seedling tray lifting device that lifts the seedling trays on the upstream equipment basket to a certain height, thereby eliminating errors caused by the seedling trays not being positioned correctly in the upstream equipment basket, ensuring that the seedling trays are within the grasping range of the tray grabber, and guaranteeing the success rate of the tray grabber.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A seedling tray lifting device includes a support frame, with side wing plates installed at both ends of the support frame. A slider is installed below the side wing plate and is movably mounted on a slide rail. Slide seats are installed at the front and rear of the slide rail and are connected to a machine base. A horizontal cylinder is installed above the machine base, and the piston rod end of the horizontal cylinder is connected to the side wing plate. Several vertical cylinders are installed at the front of the support frame, and trays are installed at the piston rod ends of the vertical cylinders. Adjustment screws are threaded to the four corners of the trays.

[0006] The support frame includes a rectangular grid frame with five support beams extending parallel to each other at the front of the grid frame. The front end of each support beam is connected to a connecting plate. The connecting plate has vertical elongated holes on both sides and is bolted to a vertical cylinder. The piston rod end of the vertical cylinder is bolted to a tray.

[0007] The tray is made of aluminum and has a folded-down edge on all four sides. The bottom of the tray is bolted to the piston rod end of the vertical cylinder via an L-shaped plate.

[0008] The rear end of the base is connected to a fixed vertical plate. The upper part of the fixed vertical plate is provided with horizontal elongated holes spaced vertically. An adjusting vertical plate is connected through the horizontal elongated holes. The bottom end of the horizontal cylinder is inserted into the two ear plate pins of the adjusting vertical plate. The piston rod end of the horizontal cylinder is connected to the two ear plate pins of the adjusting plate.

[0009] The two machine bases are arranged symmetrically from left to right and can be connected to a tray grabber or a transplanter. The distance between the two machine bases is 3150 mm.

[0010] The vertical cylinder is a twin-shaft cylinder.

[0011] The beneficial effects of this utility model are as follows: The machine base consists of two symmetrical units, one on each side, which can be connected to a tray grabber or transplanter. The distance between the two machine bases is 3150 mm, which meets the standard spacing of the tray grabber gantry frame. The tray is made of aluminum with flanges on all four sides, making it lightweight and resistant to deformation. Four adjusting screws are screwed into the dead corners of the tray; adjusting these screws according to installation errors ensures the seedling trays are level. Five support beams extend from the front of the support frame, each supporting beam mounting a tray. Each operation can lift five seedling trays, ensuring efficient operation of the lifting device. The vertical cylinder uses a dual-axis cylinder, ensuring that the trays do not rotate and that the seedling trays remain stable after being lifted. Attached Figure Description

[0015] Figure 3 yes Figure 1 Schematic diagram of the enlarged part of the middle section Figure 2 . Detailed Implementation

[0016] The following examples illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention.

[0017] like Figures 1 to 3As shown, this utility model discloses a seedling tray lifting device, which includes a support frame 1. Side wing plates 2 are respectively installed at the left and right ends of the support frame 1. A slider 3 is installed below the side wing plate 2. The slider 3 is movably mounted on the slide rail 4. Slide seats 5 are installed at the front and rear parts of the slide rail 4. The slide seats 5 are connected to the machine base 6. A horizontal cylinder 7 is installed above the machine base 6. The piston rod end of the horizontal cylinder 7 is connected to the side wing plate 2. Several vertical cylinders 8 are installed at the front of the support frame 1. A tray 9 is installed at the piston rod end of the vertical cylinder 8. Adjustment screws 10 are threaded to the four corners of the tray. Adjusting the adjustment screws according to the installation error can ensure that the seedling tray is in a horizontal state.

[0018] Specifically, the support frame 1 includes a rectangular grid frame with five parallel support beams 11 extending from the front of the grid frame. A connecting vertical plate 110 is connected to the front end of each support beam 11. The connecting vertical plate 110 has vertical elongated holes on both sides and is bolted to a vertical cylinder. The piston rod end of the vertical cylinder is bolted to a tray. The tray 9 is made of aluminum with down-turned edges, making it lightweight and resistant to deformation. The bottom of the tray 9 is bolted to the piston rod end of the vertical cylinder via an L-shaped plate. A fixed vertical plate 12 is connected to the rear end of the base 6. The upper part of the fixed vertical plate 12 has horizontally spaced elongated holes 121, through which the vertical plate 13 is connected for adjustment. The bottom end of the horizontal cylinder is inserted into the two lug pins 14 of the adjusting vertical plate. The piston rod end of the horizontal cylinder 7 is connected to the two lug pins 16 of the adjusting plate 15. The two machine bases 6 are arranged symmetrically from left to right and can be connected to a tray grabber or transplanter. The distance between the two machine bases is 3150 mm, which meets the standard spacing of the tray grabber gantry frame. The vertical cylinder is a dual-axis cylinder, which ensures that the tray does not rotate and that the seedling tray is stable after being lifted.

[0019] The working process of this utility model is as follows: The seedling tray lifting device is installed on equipment such as a seedling tray grabber or transplanter. After the seedling tray of the upstream equipment is in place, the horizontal cylinder retracts, driving the support frame to move towards the seedling tray of the upstream equipment on the slide rail. When the tray reaches the bottom of the upstream equipment tray, the piston rod of the vertical cylinder extends, driving the tray to move upward and pushing the seedling tray out of the seedling tray basket or seedling tray compartment of the upstream equipment, so as to facilitate the grabber to grab the seedling tray or the forklift action of the transplanter to pick up the seedling clump. After the seedling picking action is completed, the vertical cylinder retracts, the horizontal cylinder extends, and the lifting device returns to its original position. Adjusting the height of the four adjusting screws can further adjust the level of the seedling tray. The seedling tray lifting device lifts the seedling tray on the basket of the upstream equipment, raising the seedling tray to a certain height to eliminate the error of the seedling tray not being in place in the basket of the upstream equipment, ensuring that the seedling tray is within the grabbing range of the grabber of the tray grabber, thus ensuring the success rate of the tray grabber. Similarly, the lifting device can also lift the transplanter's seedling tray, ensuring that the transplanter's seedling-grabbing mechanism can accurately grasp the seedling clump.
