Description

Technical Field

[0001] This utility model relates to the field of seedling raising device technology, specifically a forestry planting seedling raising device. Background Technology

[0002] In order to improve the survival rate, control the quality and quantity of seedlings, and accelerate seedling growth during forestry planting, it is necessary to carry out seedling cultivation treatment. After the seeds and seedlings are cultivated in seedling cultivation devices, they have already germinated and grown to a certain extent. Therefore, they have a stronger ability to adapt to the environment than wild seeds or seedlings that are directly sown.

[0003] In the prior art, patent publication number CN114467553B discloses a forestry planting and seedling raising device, including a mounting base structure. Two support devices are symmetrically mounted on the mounting base structure. Each support device includes a first mounting base plate, a connecting horizontal plate, an anti-detachment horizontal plate, and support corner blocks. The connecting horizontal plate is installed at the inner end of the first mounting base plate, and the anti-detachment horizontal plate is installed at the inner end of the connecting horizontal plate. There are two support corner blocks symmetrically mounted at the lower end of the first mounting base plate. A mounting frame structure is mounted on the upper end of the mounting base structure. Several folding placement frame structures are symmetrically mounted in pairs on the mounting frame structure. Several mounting corner blocks are symmetrically mounted at the front and rear ends of the mounting frame structure. Two fixing devices are symmetrically mounted on each mounting corner block. Each fixing device includes a second mounting base plate, a connecting rotating arm, and a fixing pin. The connecting rotating arm and the fixing pin are respectively mounted on two end faces inside the second mounting base plate.

[0004] This type of forestry planting and seedling raising device has the following disadvantages: it uses a rotatable folding placement frame structure to achieve folding when the forestry planting and seedling raising device is not in use, but the fixing device of this forestry planting and seedling raising device lacks rigid limiting components to fix and limit the folding placement frame. In actual folding and unfolding, the folding placement frame of this forestry planting and seedling raising device is prone to instability and shaking, and even unfolds automatically in the folded state due to the lack of fixed limiting components. Therefore, we propose a forestry planting and seedling raising device. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a forestry planting and seedling raising device. Through a fixing mechanism, a worm gear drives the L-shaped connecting column to rotate, thereby fixing and limiting the movable mounting frame. This ensures that the movable mounting frame can be effectively locked when folded and unfolded, making it less prone to shaking and improving the overall stability of the forestry planting and seedling raising device. This can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a forestry planting and seedling raising device, including a base, a support frame fixedly connected to the upper surface of the base, a uniformly distributed movable placement frame rotatably connected inside the support frame, a seedling tray placed inside each movable placement frame, a limit groove provided on the front and rear surfaces of the movable placement frame, and a fixing mechanism.

[0007] The fixing mechanism includes mounting blocks, L-shaped connecting columns, rotating columns, bevel gear one, bevel gear two, and a rotating shaft. The mounting blocks are fixedly connected to the front and rear surfaces of the support frame. Symmetrically distributed rotating columns are rotatably connected inside each mounting block. L-shaped connecting columns are fixedly connected to the lower outer surface of each rotating column, and each L-shaped connecting column is fitted with an adjacent limiting groove on the same side. Bevel gear one is fixedly connected to the upper outer surface of each rotating column. A rotating shaft is rotatably connected inside each mounting block. Symmetrically distributed bevel gear two are fixedly connected to the left and right sides of the outer surface of the rotating shaft, and each bevel gear two meshes with an adjacent bevel gear one on the same side. Through the fixing mechanism, the L-shaped connecting columns are rotated using a worm gear, thereby fixing and limiting the movable mounting frame. This ensures that the movable mounting frame is effectively locked when folded and unfolded, preventing it from shaking and improving the overall stability of the forestry planting and seedling raising device.

[0008] Furthermore, the fixing mechanism also includes worm gears and worms. The worm gears are all fixedly connected to the middle of the outer surface of the rotating shaft. The worms are rotatably connected inside the mounting blocks. The worms are all meshed with the worm gears located inside the same mounting block to provide locking.

[0009] Furthermore, a knob is fixedly connected to the upper end of the worm gear to facilitate rotation of the worm gear.

[0010] Furthermore, the fixing mechanism also includes fixing rods, which are all fixedly connected to the front and rear sides of the lower surface of the movable mounting frame. Each fixing rod has a limiting groove 2 on the side away from the middle of the support frame. The L-shaped connecting column is installed in conjunction with the adjacent limiting groove 2 on the same side, which facilitates fixing the movable mounting frame when it is folded.

[0011] Furthermore, the base has sliding grooves on both the left and right sides inside, and connecting blocks are slidably connected in the sliding grooves. A fixing block is fixedly connected to the side of the connecting block away from the base. A support foot pad is fixedly connected to the lower surface of the fixing block to support the support frame and at the same time allow the connecting block to retract into the base.

[0012] Furthermore, bolts are threaded onto both the left and right sides of the upper surface of the base to fix the connecting block.

[0013] Furthermore, buffer blocks are fixedly connected to the lower surface of the movable mounting frame on the side near the support frame, and rubber pads are fixedly connected to the end of the buffer blocks near the support frame to provide support force and buffer impact when unfolded.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This forestry planting and seedling raising device has the following advantages:

[0015] The fixed mechanism uses a worm gear to drive the L-shaped connecting column to rotate, thereby fixing and limiting the movable mounting frame. This ensures that the movable mounting frame can be effectively locked when folded and unfolded, making it less prone to shaking and improving the overall stability of the forestry planting and seedling raising device.

[0022] 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.

[0023] Please see Figure 1-5This embodiment provides a technical solution: a forestry planting and seedling raising device, including a base 1, a support frame 8 fixedly connected to the upper surface of the base 1, a uniformly distributed movable mounting frame 7 rotatably connected inside the support frame 8, a seedling tray 6 placed inside each movable mounting frame 7, a limit groove opened on the front and rear surfaces of each movable mounting frame 7, a buffer block 9 fixedly connected to the lower surface of each movable mounting frame 7 near the support frame 8, a rubber pad fixedly connected to the end of each buffer block 9 near the support frame 8, sliding grooves opened on the left and right sides inside the base 1, a connecting block 2 slidably connected in each sliding groove, a fixing block 3 fixedly connected to the side of each connecting block 2 away from the base 1, a support foot pad fixedly connected to the lower surface of each fixing block 3, and the upper surface of the base 1... Both sides are threaded with bolts. Rotating the bolts causes them to move upwards, and the lower end of the bolts disengages from the upper surface of the connecting block 2. At this time, the fixing block 3 is pushed towards the base 1, causing the connecting block 2 to move into the groove and press the fixing block 3 against the base 1. Then, the bolts are reversed so that the lower end of the bolts presses against the upper surface of the connecting block 2, thus fixing the connecting block 2 and completing the folding of the forestry planting and seedling raising device. When the forestry planting and seedling raising device needs to be used, the bolts are rotated so that the lower end of the bolts disengages from the upper surface of the connecting block 2. The fixing block 3 is pulled away from the base 1 to pull the connecting block 2 out of the groove. The bolts are reversed so that the lower end of the bolts presses against the upper surface of the connecting block 2, thus fixing the connecting block 2. The device also includes a fixing mechanism 4.

[0024] Fixed mechanism 4 includes mounting blocks 41, L-shaped connecting columns 42, rotating columns 43, bevel gear 44, bevel gear 45, and rotating shaft 46. Mounting blocks 41 are fixedly connected to the front and rear surfaces of the support frame 8. Symmetrically distributed rotating columns 43 are rotatably connected inside each mounting block 41. L-shaped connecting columns 42 are fixedly connected to the lower outer surface of each rotating column 43. Each L-shaped connecting column 42 mates with an adjacent limiting groove on the same side. Bevel gear 44 is fixedly connected to the upper outer surface of each rotating column 43. Rotating shaft 46 is rotatably connected inside each mounting block 41. Bevel gear 45 is fixedly connected to the left and right sides of the outer surface of the rotating shaft 46. Symmetrically distributed bevel gears 45, each meshing with an adjacent bevel gear 44 on the same side. The fixing mechanism 4 also includes worm gears 47 and worms 48. Worm gears 47 are fixedly connected to the middle of the outer surface of the rotating shaft 46. Worms 48 are rotatably connected inside each mounting block 41, and each worm 48 meshes with a worm gear 47 located inside the same mounting block 41. A knob 5 is fixedly connected to the upper end of the worm 48. The fixing mechanism 4 also includes fixing rods 49, which are fixedly connected to the front and rear sides of the lower surface of the movable mounting frame 7. Limiting grooves are provided on the side of the fixing rods 49 away from the middle of the support frame 8. All L-shaped connecting columns 42 are installed in conjunction with the adjacent limiting grooves on the same side. When the forestry planting and seedling raising device is idle, remove the seedling tray 6, rotate the knob 5 to rotate the worm gear 78, drive the worm wheel 47 to rotate, drive the rotating shaft 46 to rotate, drive the bevel gear 45 to rotate, drive the bevel gear 44 to rotate, drive the L-shaped connecting column 43 to rotate, so that the end of the L-shaped connecting column 42 away from the mounting block 41 is disengaged from the limiting groove 1. At this time, rotate the movable mounting frame 7 90° so that the movable mounting frame 7 is in a vertical state and located inside the support frame 8, driving the fixed rod 49 to move, so that the fixed rod 49 rotates 90°. At this time, reverse the knob 5 to make the L-shaped connecting column 42 rotate. Rotate the L-shaped connecting column 42 so that the end of the L-shaped connecting column 42 away from the mounting block 41 is inserted into the limiting groove 2. Rotate the knob 5 so that the end of the L-shaped connecting column 42 away from the mounting block 41 is disengaged from the limiting groove 2. Then rotate the movable mounting frame 7 so that the movable mounting frame 7 is in a horizontal state. At this time, the buffer blocks 9 on the lower surface of the movable mounting frame 7 on both sides make contact first, and the rubber pads absorb the impact force generated when they make contact. Then reverse the knob 5 so that the end of the L-shaped connecting column 42 away from the mounting block 41 is inserted into the limiting groove 1, thus completing the unfolding and fixing of the movable mounting frame 7. Then place the seedling tray 6 in the movable mounting frame 7 for seedling cultivation.

[0025] The working principle of the forestry planting and seedling raising device provided by this utility model is as follows: When the forestry planting and seedling raising device is idle, the seedling tray 6 is removed, the knob 5 is rotated to make the worm 78 rotate, which drives the worm wheel 47 to rotate, which drives the rotating shaft 46 to rotate, which drives the bevel gear 45 to rotate, which drives the bevel gear 44 to rotate, which drives the L-shaped connecting column 43 to rotate, so that the end of the L-shaped connecting column 42 away from the mounting block 41 is disengaged from the limiting groove 1. At this time, the movable mounting frame 7 is rotated 90°, so that the movable mounting frame 7 is in a vertical state and located inside the support frame 8, which drives the fixed rod 49 to move, so that the fixed rod 49 rotates 90°. At this time, the knob 5 is reversed to make the L-shaped connecting column 42 rotate, so that the end of the L-shaped connecting column 42 away from the mounting block 41 is inserted into the limiting groove 2. The bolt is rotated to make the bolt move upward, and the lower end of the bolt is disengaged from the upper surface of the connecting block 2. At this time, the fixed block 3 is pushed towards the base 1, so that the connecting block 2 moves into the sliding groove, so that the fixed block 3 is tightly attached to the base 1. Turn the bolt so that the lower end of the bolt is close to the upper surface of the connecting block 2 to fix the connecting block 2, thus completing the folding of the forestry planting and seedling raising device. When the forestry planting and seedling raising device is needed, turn the bolt so that the lower end of the bolt is disengaged from the upper surface of the connecting block 2. Pull the fixing block 3 away from the base 1 to pull the connecting block 2 out of the slide groove. Turn the bolt back so that the lower end of the bolt is close to the upper surface of the connecting block 2 to fix the connecting block 2. Turn the knob 5 so that the end of the L-shaped connecting column 42 away from the mounting block 41 is disengaged from the limiting groove 2. Then rotate the movable mounting frame 7 so that the movable mounting frame 7 is in a horizontal state. At this time, the buffer blocks 9 on the lower surface of the movable mounting frame 7 on both sides make contact first. The rubber pad absorbs the impact force generated when contacting. Then turn the knob 5 back so that the end of the L-shaped connecting column 42 away from the mounting block 41 is inserted into the limiting groove 1 to complete the unfolding and fixing of the movable mounting frame 7. Then place the seedling tray 6 in the movable mounting frame 7 for seedling raising.
