Description

Technical Field

[0001] This utility model relates to the field of pear tree breeding technology, and in particular to a three-dimensional cultivation device for planting pear tree seedlings. Background Technology

[0002] In the cultivation of pear seedlings, traditional flat planting methods occupy a large land area and have low space utilization, resulting in a limited number of seedlings cultivated per unit area, which is not conducive to large-scale, intensive production. Although there are currently vertical cultivation racks for cultivating pear seedlings, which can improve space utilization to some extent, the cultivation layers are usually fixed or secured with bolts. When pear seedlings are at different growth stages, their space requirements vary, and traditional vertical cultivation racks cannot be easily and quickly adjusted. Furthermore, each cultivation layer has a certain weight, which increases the workload of workers when adjusting the position, making it time-consuming and labor-intensive. Therefore, there is an urgent need for a cultivation device to solve the above problems. Utility Model Content

[0003] The present invention aims to provide a three-dimensional cultivation device for planting pear seedlings, so as to solve the problems of the current cultivation racks being unable to be adjusted quickly and conveniently, and being time-consuming and labor-intensive.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] The basic technical solution provided by this utility model is: a three-dimensional cultivation device for planting pear seedlings, including a base, a mounting frame, and a cultivation board. Fixed columns are provided at the four corners of the top surface of the base. Drip irrigation components are installed on the fixed columns. Multiple sets of mounting frames are slidably mounted on the fixed columns. A compression rod, a movable frame, and a rotating plate are respectively installed in the cavities on both sides of the mounting frame. One end of the compression rod is connected to a positioning spring, and the other end of the compression rod contacts one side of the bottom of the rotating plate. The rotating plate is rotatably mounted in the cavity within the mounting frame via a rotating shaft. The bottom end of the rotating plate is engaged with a helical rack, which is mounted on the fixed columns. A limiting rod at the top of the rotating plate passes through a through groove on the movable frame. Two sets of movable frames on both sides of the mounting frame are connected by a crossbar. A compression spring and a positioning frame are respectively fitted onto one end of the movable frame. The compression spring is connected to one end of the positioning frame, and an arc-shaped piece is provided at the other end of the positioning frame, located on one side of the fixed column. A cultivation board is mounted on the mounting frame, and multiple sets of placement holes are provided on the cultivation board.

[0006] Preferably, the drip irrigation assembly includes a water delivery pipe and multiple sets of fixed pipes. The water delivery pipe is equipped with a control valve. The fixed pipes are connected to the water delivery pipes via flexible hoses. The fixed pipes are clamped onto elastic brackets, which are mounted on the cultivation board. The fixed pipes are equipped with multiple sets of shaping tubes, which correspond to the placement holes.

[0007] Preferably, the cultivation board is provided with multiple sets of universal ball seats, and locking bolts are inserted inside the universal ball seats. The universal ball seats are connected to universal ball heads, which are located on the back of the reflector. The reflector is located on one side of the placement hole, and fans are provided on both sides of the mounting frame.

[0008] Preferably, the base is provided with a water collection trough, a drain valve is provided on the side of the base, and casters are provided on the bottom of the base.

[0009] Preferably, a handle is provided on the crossbar, the handle extends out of the mounting frame and is located inside the handle, and the handle is set on the mounting frame.

[0010] Preferably, a friction plate is provided on the arc-shaped plate, and a soft rubber ring is provided at the placement hole.

[0011] The principle and beneficial effects of the basic technical solution are as follows: Containers for cultivating pear seedlings can be placed through the placement holes. The cultivation board is supported by the mounting frame. Under the action of the positioning spring, the squeezing rod presses against the bottom end of the rotating plate, keeping it locked within the oblique teeth of the oblique toothed rack, thus fixing the mounting frame. By pushing the moving frame, the rotating plate is rotated, causing the bottom end of the rotating plate to separate from the oblique toothed rack, thereby releasing the lock on the mounting frame and allowing for position adjustment. This is more convenient than traditional cultivation frame adjustments. At the same time, after pushing the moving frame, the arc-shaped piece on the positioning frame contacts the fixed column, providing a certain friction force to prevent the mounting frame from descending rapidly. The operator only needs to control the force of the arc-shaped piece against the fixed column to control the slow descent of the mounting frame, saving time and effort. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0019] like Figures 1-5 As shown: A three-dimensional cultivation device for planting pear seedlings includes a base 1, a mounting frame 2, and a cultivation plate 4. Fixed columns 9 are provided at the four corners of the top surface of the base 1, and drip irrigation components are mounted on the fixed columns 9. Multiple sets of mounting frames 2 are slidably mounted on the fixed columns 9. A pressing rod 19, a movable frame 21, and a rotating plate 27 are respectively installed in the cavities on both sides of the mounting frame 2. One end of the pressing rod 19 is connected to a positioning spring 20, and the other end of the pressing rod 19 contacts one side of the bottom of the rotating plate 27. The rotating plate 27 is rotatably mounted in the cavity within the mounting frame 2 via a rotating shaft. The bottom end of the rotating plate 27 is engaged with a helical gear rack 26, which is mounted on the fixed columns 9. A limiting rod at the top of the rotating plate 27 passes through the movable frame 21. Within the through groove, the movable frame 21 can move horizontally within the cavity of the mounting frame 2. The two sets of movable frames 21 on both sides of the mounting frame 2 are connected by a crossbar 14. One end of the movable frame 21 is respectively fitted with a compression spring 22 and a positioning frame 23. The compression spring 22 is connected to one end of the positioning frame 23. The other end of the positioning frame 23 is provided with an arc-shaped piece 24. The arc-shaped piece 24 is located on one side of the fixed column 9. The helical toothed rack 26 is located between the two sets of arc-shaped pieces 24. After the arc-shaped piece 24 moves, it contacts the surface of the fixed column 9 on both sides of the helical toothed rack 26, but does not contact the helical toothed rack 26. A cultivation board 4 is provided on the mounting frame 2. The cultivation board 4 has multiple sets of placement holes 18, which are adapted to the containers for cultivating pear seedlings.

[0020] The specific implementation process is as follows:

[0021] In use, containers for cultivating pear seedlings are placed through the placement holes 18 on the cultivation board 4. When it is necessary to raise the cultivation board 4, the operator only needs to push the mounting frame 2 upward along the fixed column 9. Since the rotating plate 27 and the oblique teeth on the oblique rack 26 are locked in one direction, when the mounting frame 2 is lifted upward, the rotating plate 27 automatically separates from the oblique teeth on the oblique rack 26 and moves into the corresponding oblique teeth. After the height adjustment is in place, under the action of the positioning spring 20, the squeezing rod 19 is pushed to press against one side of the bottom end of the rotating plate 27, so that the rotating plate 27 is always engaged in the oblique teeth of the oblique rack 26, automatically locking and fixing the mounting frame 2. When it is necessary to lower the cultivation board 4, the operator only needs to slightly lift the mounting frame 2 and pull the crossbar 14 to move the moving frame 21, causing the rotating plate 27 to rotate and separate from the oblique rack 26, releasing the lock on the mounting frame 2. While pushing the moving frame 21 to move, the rotating plate 27 rotates, separating from the oblique rack 26, releasing the lock on the mounting frame 2. The frame 21 compresses the spring 22 and pushes the positioning frame 23 to move, causing the arc-shaped piece 24 on the positioning frame 23 to extend out of the mounting frame 2 and contact the fixed column 9. Before the rotating plate 27 completely separates from the helical rack 26, the arc-shaped piece 24 contacts the fixed column 9, continuously pushing the moving frame 21 so that the arc-shaped piece 24 presses against the fixed column 9, providing a certain friction for the mounting frame 2 and preventing the mounting frame 2 from falling rapidly after being unlocked. The operator only needs to control the force of pulling the crossbar 14 to control the force of the moving frame 21 compressing the spring 22, thereby controlling the force of the spring 22 feeding back to the positioning frame 23, changing the friction between the arc-shaped piece 24 and the fixed column 9, thus slowly lowering the height of the mounting frame 2. The operator does not need to lift the mounting frame 2 with force throughout the process. After adjustment, the crossbar 14 is released, and the rotating plate 27 automatically locks the mounting frame 2, thus saving time and effort for space adjustment and meeting the growth needs of the pear tree.

[0022] In this embodiment, the drip irrigation assembly includes a water supply pipe 5 and multiple sets of fixed pipes 7. A control valve 6 is installed on the water supply pipe 5. The fixed pipes 7 are connected to the water supply pipe 5 via flexible hoses and are secured to an elastic bracket 16, which is mounted on a cultivation board 4. Multiple sets of shaping tubes 8 are installed on the fixed pipes 7, with each shaping tube corresponding to a placement hole 18. Drip irrigation holes are located at the ends of the shaping tubes 8. Water is supplied to the entire drip irrigation assembly via an external water source connected to the water supply pipe 5. The water flow rate can be controlled by adjusting the control valve 6, thereby controlling the drip irrigation rate. The fixed pipes 7 and the water supply pipe 5 are connected by a flexible hose of a certain length, ensuring normal water supply after adjusting the position of the cultivation board 4. The shaping tubes 8 can be bent freely and automatically retain their shape after bending, allowing workers to adjust the shaping tubes 8 to the roots of the pear seedlings, improving drip irrigation efficiency.

[0023] In this embodiment, the cultivation board 4 is provided with multiple sets of universal ball seats 28, and locking bolts 31 are inserted inside the universal ball seats 28. The universal ball seats 28 are connected to universal ball heads 29, which are located on the back of the reflector 30. The reflector 30 is located on one side of the placement hole 18. Fans 11 are provided on both sides of the mounting frame 2. The fans 11 are controlled by a controller to start and stop at set times, providing a suitable ventilation environment for the pear seedlings. Loosening the locking bolts 31 locks the universal ball heads 29. The position and angle of the reflector 30 can be adjusted according to the actual situation, so that the light is reflected to the middle and lower parts of the pear seedlings through the reflector 30, improving the uniformity of light and providing a suitable growth environment for the pear seedlings.

[0024] In this embodiment, a water collection tank 12 is provided on the base 1, a drain valve 13 is provided on the side of the base 1, and a caster wheel 10 with a self-locking structure is provided on the bottom surface of the base 1. Excess water is collected through the water collection tank 12 and discharged out of the device through the drain valve 13 for subsequent secondary use; the caster wheel 10 allows for easy movement of the device and adjustment of its position.

[0025] In this embodiment, a handle 15 is provided on the crossbar 14. The handle 15 extends out of the mounting bracket 2 and is located inside the handle 3, which is mounted on the mounting bracket 2. When the operator holds the handle 3 and pulls the handle 15 with their fingers, the crossbar 14 can be easily pulled, and the tension can be controlled more conveniently and accurately, thereby controlling the friction between the arc-shaped piece 24 and the fixed post 9 and facilitating adjustment.

[0026] In this embodiment, a friction plate 25 is provided on the arc-shaped plate 24, and a soft rubber ring 17 is provided at the placement hole 18. The friction plate 25 can increase friction and reduce the tension applied by the operator; the soft rubber ring 17 can increase friction, provide cushioning, prevent the container for cultivating pear seedlings from moving, and improve the stability of the device.
