Description

Technical Field

[0001] The utility model relates to the technical field of seedling lifting machines, in particular to a seedling lifting machine for garden transplanting. Background Art

[0002] The seedling lifter is a machine used to lift the seedlings from the soil in the nursery. The commonly used seedling lifters use a U-shaped hook knife to cut the soil layer and the roots in the soil layer. However, after lifting the seedlings, the seedlings need to be manually removed before they can be used next time. Each time the seedlings are lifted, the seedlings need to be manually removed and the machine needs to be manually moved. If one person operates the seedling lifter, the efficiency will be seriously affected. The degree of mechanization is low, and due to the presence of the hook knife and other mechanical structures, it is very easy to cause mechanical damage to personnel. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a garden transplanting seedling lifting machine that can place seedlings and improve the operational process and safety.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A seedling lifting machine for garden transplanting, comprising a hook knife and a mounting frame fixedly connected to a motor vehicle body, wherein a blade is arranged on one side of the hook knife; and a landing gear, wherein the landing gear is U-shaped and has an opening facing one side, and a hook knife rotating structure for driving the hook knife to rotate and a seedling clamping structure for clamping the seedling are installed on the landing gear;

[0006] The mounting frame is connected to the moving frame via a horizontal moving structure, the moving frame is connected to the rotating frame via a rotating structure, lifting cylinders are installed on both sides of the rotating frame, and the cylinder rods of the lifting cylinders are fixedly connected to the landing gear via a connecting block.

[0007] In this way, the motor vehicle body is connected to the seedling lifter through the mounting frame, which makes it convenient to drive the seedling lifter to move through the motor vehicle body. Through the cooperation of the hook knife rotating structure, the seedling clamping structure, the horizontal moving structure and the rotating structure, the process of driving the hook knife to cut the soil layer and roots, lift and place the seedlings is realized.

[0008] Specific process:

[0009] 1. The motor vehicle body drives the seedling lifting machine to move to the side of the seedlings that need to be lifted, and the seedlings reach the U-shaped opening of the landing gear, and the seedling clamping structure clamps the seedlings;

[0010] 2. The hook knife rotating structure drives the hook knife to rotate and cut the soil layer and roots;

[0011] 3. The lifting cylinder drives the landing gear to rise, and then drives the sapling to rise through the sapling clamping structure;

[0012] 4. The rotating structure drives the landing gear to rotate 90 degrees, the moving structure drives the moving frame to move to one side and into position, and the hook knife rotating structure drives the hook knife to reset to the side close to the rotating frame. The distance between the hook knife and its rotation center is smaller than the radius of the root system of the sapling. The hook knife is tilted at this moment, and the sapling clamping structure is loosened. When the sapling falls, the root system touches the inclined surface of the hook knife, and the hook knife provides an outward force to the sapling, causing the sapling to tilt and fall away from the landing gear, thereby causing the sapling to move to one side after lifting.

[0013] 5. All structures of the seedling lifting machine are reset to the initial state, and the motor vehicle drives the seedling lifting machine to move to the side of the next seedling that needs to be lifted;

[0014] 6. Repeat the above process 1-5 until all the seedlings are removed. Finally, the operator loads the removed seedlings onto the mobile rack and transfers them to the packaging position. After the root system is packaged, the packaging operation can be carried out.

[0015] Among them, the hook knife rotating structure includes a gear shaft rotatably installed on both sides of the landing gear, the inner end of the gear shaft is fixedly connected with a knife seat, the knife seat is fixedly connected to the hook knife, the outer end of the gear shaft is fixedly installed with a gear, the gear is meshed with a rack, the landing gear is fixedly installed with a moving cylinder opposite to the gear, the cylinder rod of the moving cylinder is fixedly connected to the rack, the rack is fixed with a slider, the landing gear is fixed with a slide rail, and the slider slides with the slide rail.

[0016] The sapling clamping structure includes two clamping plates, the upper and lower ends of the outer sides of the clamping plates are rotatably connected to the cylinder rod of the clamping cylinder, and the cylinder body of the clamping cylinder is rotatably connected to the landing gear;

[0017] The landing gear is fixed with two reinforcement frames, and the inner end of the clamping plate is rotatably connected to the reinforcement frame.

Through the cooperation of the hook knife rotating structure, the seedling clamping structure, the horizontal moving structure and the rotating structure, the process of driving the hook knife to cut the soil layer and roots, lift and place the seedlings is realized.

[0033] Specific process:

[0034] 1. The motor vehicle body drives the seedling lifting machine to move to the side of the seedlings that need to be lifted, and the seedlings reach the U-shaped opening of the landing gear, and the seedling clamping structure clamps the seedlings;

[0035] 2. The hook knife rotating structure drives the hook knife to rotate and cut the soil layer and roots;

[0037] 4. The rotating structure drives the landing gear to rotate 90 degrees, the moving structure drives the moving frame to move to one side and into position, and the hook knife rotating structure drives the hook knife to reset to the side close to the rotating frame. The distance between the hook knife and its rotation center is smaller than the radius of the root system of the sapling. The hook knife is tilted at this moment, and the sapling clamping structure is loosened. When the sapling falls, the root system touches the inclined surface of the hook knife, and the hook knife provides an outward force to the sapling, causing the sapling to tilt and fall away from the landing gear, thereby causing the sapling to move to one side after lifting.

[0038] 5. All structures of the seedling lifting machine are reset to the initial state, and the motor vehicle drives the seedling lifting machine to move to the side of the next seedling that needs to be lifted;

[0039] 6. Repeat the above process 1-5 until all the seedlings are removed. Finally, the operator loads the removed seedlings onto the mobile rack and transfers them to the packaging position. After the root system is packaged, the packaging operation can be carried out.

[0041] In this way, the cylinder drives the rack to move, the rack meshes with the gear, and then drives the gear and the gear shaft to rotate, thereby driving the hook knife to rotate. Compared with the motor driving the hook knife to rotate, the stability can be improved.
