Description

Technical Field

[0001] The utility model relates to the technical field of nursery stock cultivation in forestry engineering, and particularly relates to a forestry engineering nursery stock cultivation device with adjustable spacing between nursery shelves. Background Technique

[0002] Nursery stock cultivation is a key link in forestry engineering construction, directly affecting the construction effectiveness of forestry engineering. Through scientific nursery stock cultivation techniques, the survival rate, growth rate and disease resistance of nursery stocks can be improved, thereby enhancing the ecological functions of forests and improving the quality and yield of forest trees. In the process of nursery stock cultivation, seed selection, germination acceleration, selection and preparation of planting sites are all key steps, and these measures help to improve the adaptability and growth potential of nursery stocks.

[0003] The utility model patent with the authorization announcement number of CN220023685U discloses "A Forestry Engineering Nursery Stock Cultivation Device", which includes a bottom plate. Both sides of the upper end of the bottom plate are provided with chutes. A fixed frame is arranged at the upper end of the bottom plate, and a plurality of fixed frames are evenly distributed on the upper end of the bottom plate. The outer surface of the lower end of the fixed frame is movably provided with rollers for moving the fixed frame through a rotating shaft, and the rollers are movably clamped inside the chutes. A plurality of planting grooves are evenly and fixedly arranged inside the fixed frame. A transmission mechanism for driving the fixed frame to move is arranged between the inside of the fixed frame and the rollers. By arranging a plurality of fixed frames and planting grooves, initially, a plurality of fixed frames and planting grooves are stacked together, which can effectively reduce the overall occupied area of the device and maximize the use of space for nursery stock cultivation.

[0004] However, the above-mentioned prior art solutions still have the following deficiencies: Stacking a plurality of fixed frames and planting grooves together will cause the nursery stocks in the stacked part to not receive sufficient sunlight, which is not conducive to the growth of nursery stocks. At the same time, if the staff wants to maintain the nursery stocks in the middle fixed frame, they need to manually move the front fixed frame away. Since the nursery stock box is generally heavy after being filled with nursery stocks, the operation is relatively laborious and not convenient enough. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a forestry engineering nursery stock cultivation device with adjustable spacing between nursery shelves, which can adjust the spacing between nursery shelves, facilitate the movement of the nursery stock box, avoid stacking, and enable the nursery stocks to receive sufficient sunlight.

[0006] To solve the above technical problems, the utility model provides the following technical solutions:

[0007] A forestry engineering nursery stock cultivation device with adjustable spacing between nursery shelves includes an installation frame, and an equidistant telescopic mechanism is arranged on the installation frame;

[0008] The equidistant telescopic mechanism includes a servo motor, which is fixedly installed on the mounting frame. The output end of the servo motor is fixedly connected to a lead screw. The lead screw is rotatably connected through a fixed plate, and the other end of the lead screw is rotatably connected to the mounting frame. Three moving platforms are sleeved on the lead screw. One of the moving platforms is fixedly connected through an inner threaded pipe, and the inner threaded pipe is threadedly connected to the lead screw. The top surfaces of the three moving platforms are all fixedly connected with a first rotating shaft. A first connecting rod is rotatably connected to the first rotating shaft. One end of the first connecting rod is rotatably connected to a second rotating shaft, and a second connecting rod is rotatably connected to the second rotating shaft. The bottom surface of the moving platform is fixedly connected with a seedling raising frame, and three partition plates are fixedly connected inside the seedling raising frame.

[0009] Preferably, a reinforcing plate corresponding to the three partition plates is fixedly connected to the rear surface of the seedling raising frame, and the reinforcing plate is inclined.

[0010] Preferably, plant growth lamps are fixedly installed on the bottom surfaces of the three partition plates and the inner top surface of the seedling raising frame, and the axes of the plant growth lamps coincide with the axis of the seedling raising frame.

[0011] Preferably, four rollers are rotatably installed at the bottom of the seedling raising frame, and the rollers are symmetrically distributed about the axis of the seedling raising frame.

[0012] Preferably, two limiting slide bars are slidably penetrated through the moving platform. One end of the limiting slide bar is fixedly connected to the fixed plate, and the other end of the limiting slide bar is fixedly connected to the inner surface of the mounting frame.

[0013] Preferably, an avoidance round hole is formed in the moving platform, and the diameter of the avoidance round hole is larger than the diameter of the lead screw.

[0014] Preferably, cross plates are fixedly connected to both sides of the mounting frame. Both ends of the fixed plate are fixedly connected to the inner surface of the cross plates, and the height position of the bottom surface of the cross plates is higher than the height position of the top surface of the seedling raising frame.

[0015] Compared with the prior art, the beneficial effects achieved by the present utility model are:

[0016] First, through the setting of the equidistant telescopic mechanism, first fix the mounting frame to the crossbeam in the seedling raising room or install it into the wall of the seedling raising room through expansion bolts, and install one end of the mounting frame with a diagonal bracing plate to fixedly support the mounting frame. Start the servo motor to drive the screw rod to rotate, and then drive the inner corrugated pipe to perform linear reciprocating motion. The inner corrugated pipe drives the moving table fixedly connected to it to move. Since the three moving tables and the fixed plate are connected by three groups of rotating shafts one, connecting rods one, rotating shafts two, and connecting rods two, when the inner corrugated pipe drives the moving table fixedly connected to it to move, the connecting rod one and the connecting rod two expand and contract, causing the remaining moving tables to be driven to move in the same direction. Since the bottom of the moving table is fixedly connected to the seedling raising frame, and the bottom of the seedling raising frame is rotatably installed with rollers, when the moving table moves, it can drive the seedling raising frame to move together, adjust the spacing between the seedling raising frames, facilitate the movement of the seedling raising boxes, avoid stacking, and enable the seedlings to receive sufficient sunlight.

[0017] Second, through the setting of the plant growth lamp, when the weather is bad or the seedlings need light at night, the plant growth lamp can be used to supplement light continuously and stably. Through the setting of the reinforcing plate, the stability of the seedling raising frame can be enhanced. At the same time, the gaps formed between the reinforcing plates can facilitate ventilation inside the seedling raising frame, adjust the temperature and humidity inside it, and provide a more suitable growth environment for the seedlings.

Detailed Description of the Specific Embodiment

[0024] The following will further describe the specific embodiment of the present utility model in detail with reference to the drawings.

[0025] Please refer to Figures 1-5, a forestry engineering seedling cultivation device with adjustable spacing between seedling racks, including a mounting frame 1, on which an equidistant telescopic mechanism is provided;

[0026] The equidistant telescopic mechanism includes a servo motor 2, which is fixedly installed on the mounting frame 1. The output end of the servo motor 2 is fixedly connected to a lead screw 3. A fixing plate 4 is rotatably connected through the lead screw 3. The other end of the lead screw 3 is rotatably connected to the mounting frame 1. Three moving platforms 5 are sleeved on the lead screw 3. One of the moving platforms 5 is fixedly connected through an internal thread tube 6, and the internal thread tube 6 is threadedly connected to the lead screw 3. The top surfaces of the three moving platforms 5 are all fixedly connected with a first rotating shaft 7. A first connecting rod 8 is rotatably connected to the first rotating shaft 7. One end of the first connecting rod 8 is rotatably connected to a second rotating shaft 9. A second connecting rod 10 is rotatably connected to the second rotating shaft 9. A seedling rack 11 is fixedly connected to the bottom surface of the moving platform 5. Three partition plates 12 are fixedly connected inside the seedling rack 11.

[0027] Specifically, a reinforcing plate 13 corresponding to the three partition plates 12 is fixedly connected to the rear surface of the seedling rack 11, and the reinforcing plate 13 is inclined.

[0028] Through the above technical solution, several triangles can be formed by the partition plate 12 and the reinforcing plate 13, enhancing the stability of the seedling rack 11 and the partition plate 12. At the same time, the gap between the partition plate 12 and the reinforcing plate 13 is beneficial to the ventilation inside the seedling rack 11, regulating the temperature and humidity inside the seedling rack 11, and providing a suitable environment for the growth of seedlings.

[0029] Specifically, plant growth lights 14 are fixedly installed on the bottom surfaces of the three partition plates 12 and the inner top surface of the seedling rack 11, and the axes of the plant growth lights 14 coincide with the axis of the seedling rack 11.

[0030] Through the above technical solution, continuous and stable light can be provided for the seedlings in bad weather or at night, promoting the growth of the seedlings.

[0031] Specifically, four rollers 15 are rotatably installed at the bottom of the seedling rack 11, and the rollers 15 are symmetrically distributed about the axis of the seedling rack 11.

[0032] Through the above technical solution, it is convenient for the moving platform 5 to drive the seedling rack 11 to move together when moving.

[0033] Specifically, two limiting slide rods 16 are slidably and penetratingly connected to the moving platform 5. One end of the limiting slide rod 16 is fixedly connected to the fixing plate 4, and the other end of the limiting slide rod 16 is fixedly connected to the inner surface of the mounting frame 1.

[0034] Through the above technical solution, when the mobile station 5 moves on the lead screw 3, it can be limited, so that it will not deflect during operation.

[0035] Specifically, an avoidance round hole is formed on the mobile station 5, and the diameter dimension of the avoidance round hole is larger than the diameter dimension of the lead screw 3.

[0036] Through the above technical solution, the mobile station 5 can move more smoothly during the movement, and at the same time, the wear of the lead screw 3 is reduced, and its service life is extended.

[0037] Specifically, cross plates 17 are fixedly connected to both sides of the mounting frame 1, both ends of the fixing plate 4 are fixedly connected to the inner surface of the cross plates 17, and the bottom height position of the cross plates 17 is higher than the top height position of the seedling raising frame 11.

[0038] Through the above technical solution, the fixing plate 4 fixedly connected to the cross plate 17 can limit the maximum and minimum distances of the telescopic device, and the bottom height position of the cross plate 17 being higher than the top height position of the seedling raising frame 11 enables the equidistant telescopic mechanism not to be blocked by the cross plate 17 during operation.

[0039] During use, the mounting frame 1 is fixedly installed on the cross beam in the seedling raising room or installed in the wall of the seedling raising room through expansion bolts, and one end of the mounting frame 1 is installed with a diagonal bracing plate for fixed support of the mounting frame 1. The servo motor 2 is started to drive the lead screw 3 to rotate, and then the inner corrugated pipe 6 is driven to perform a linear reciprocating motion. The inner corrugated pipe 6 drives the mobile station 5 fixedly connected thereto to move. Since the three mobile stations 5 and the fixing plate 4 are connected by three groups of rotating shafts 7, connecting rods 8, rotating shafts 9 and connecting rods 10, when the inner corrugated pipe 6 drives the mobile station 5 fixedly connected thereto to move, the connecting rods 8 and 10 expand and contract, so that the other mobile stations 5 are driven to move in the same direction. Since the bottom of the mobile station 5 is fixedly connected to the seedling raising frame 11, and the bottom of the seedling raising frame 11 is rotatably installed with rollers 15, when the mobile station 5 moves, the seedling raising frame 11 can be driven to move together, which is convenient for adjusting the distance between the seedling raising frames 11. When the seedling raising frame 11 extends, it is convenient for the staff to maintain the seedlings in each seedling raising frame 11, and it is convenient for the seedlings to receive sufficient sunlight usually. When the seedling raising frames 11 are stacked, space can be saved. When the weather is bad or the seedlings need light at night, the plant growth lamp 14 can be used to supplement the light continuously and stably. Through the arrangement of the reinforcing plates 13, the stability of the seedling raising frame 11 can be enhanced, and at the same time, the gaps formed between the reinforcing plates 13 can be beneficial to ventilation inside the seedling raising frame 11, adjust the temperature and humidity inside it, and provide a more suitable growth environment for the seedlings.
