[0004] However, during the cultivation process, the seedlings on the tray racks often need to be watered or sprayed with nutrient solution regularly, but the above-mentioned device is not conducive to collecting excess water on the tray racks, which easily leads to waste. Summary of the Invention

[0005] In response to the problems existing in the prior art, the present invention provides a cultivation device for forest seedling cultivation, which has the advantage of diverting and transporting excess spray water or nutrient solution on each layer of tray through a water collecting tray to avoid waste. The tray is not only convenient for height adjustment, but also can drive the ring cutting piece to intermittently cut off the roots of seedlings that are excessively adhered to the inner wall of the cultivation tube. It can also drive the water collecting tray to lift the soil layer and seedlings upward, so as to facilitate the rapid and safe removal of the seedlings after cultivation, avoid damage to the seedlings during removal, effectively improve the cultivation efficiency and work efficiency, and solve the problem in the prior art that it is not conducive to collecting excess water or nutrient solution sprayed on the tray rack, which easily causes waste.

[0006] The present invention is achieved as follows: a cultivation device for forest seedling cultivation includes a base, wherein the four corners of the base are fixedly connected to support rods, the tops of the support rods are fixedly connected to support plates, two screw rods are connected between the base and the support plates through bearings, a tray is installed between the screw rods through telescopic parts, a rotating rod passes through the trays, the two ends of the rotating rod are respectively connected to the base and the support plates through bearings, the interior of the tray is fixedly connected to a cultivation tube by bolts, a ring cutting piece is slidably connected to the inner wall of the cultivation tube, the ring cutting piece includes an arc-shaped slice, the screw rod can drive the arc-shaped slice to rotate along the inner wall of the cultivation tube through the rotating rod, and a water collecting tray is slidably inserted into the bottom of the tray.

[0007] Through this setting, the cooperation of the screw rod and the telescopic part can drive multiple trays to adjust the height of the whole. The water collecting tray is used to guide and transport the excess water sprayed during the cultivation process to avoid waste. The cooperation between the screw rod, the rotating rod, the telescopic part and the ring cutting part facilitates the intermittent rotation of the arc slice along the inner wall of the cultivation tube, and then facilitates the intermittent cutting of the roots of the seedlings that are excessively adhered to the inner wall of the cultivation tube, avoiding root damage when the seedlings are removed. When the seedlings are removed, the water collecting tray can also lift the soil layer and the seedlings upward, thereby facilitating the rapid and safe removal of the seedlings after cultivation, avoiding damage to the seedlings during removal, and helping to improve the survival rate of seedling transplantation and planting, thereby effectively improving the cultivation efficiency and work efficiency.

[0008] As a preferred embodiment of the present invention, the four corners of the tray are slidably mounted on the support rod, and both ends of the tray are mounted on the screw rod.

A motor is fixedly installed on the top of the support plate, and the output end of the motor is fixedly connected to the central axis of the main gear.

[0009] With this arrangement, the toothed belt can easily drive the main gear and the slave gear to rotate synchronously in the same direction, thereby driving the two screw rods to rotate synchronously, thereby facilitating the tray on the telescopic part to perform overall height adjustment movement, making the cultivation rack easy to use.

The inner middle part of the telescopic long rod is hingedly connected to the side wall of the tray through a pin.

[0011] Through this setting, the stability of the connection structure between the telescopic part and the screw rod is effectively improved. When the motor drives the screw rod to rotate, it drives the telescopic block to move in a straight line along the screw rod, and then drives the telescopic long rod, telescopic short rod and tray to extend upward and retract downward, thereby realizing the height adjustment between the trays.

A limiting block is fixedly connected to the inner wall of the rotating drum, and the limiting block is inserted into the limiting groove.

[0013] With this arrangement, through the meshing transmission principle of the main gear and the gear ring, when the lead screw drives the main gear to rotate, the gear ring and the rotating rod can be driven to rotate synchronously. The stability of the rotating drum during operation is ensured by the limit block and the limit groove, so that the tray will not rotate with the rotating drum, and the rotating drum will move up and down with the tray while rotating.

[0014] As a preferred embodiment of the present invention, a second toothed disc is fixedly connected to the bottom side wall of the rotating cylinder, the bottom of the tray corresponding to the cultivation cylinder is connected to the first toothed disc through a bearing, the second toothed disc and the adjacent first toothed disc are meshed and connected, the first toothed discs are meshed and connected with each other, the bottom of the arc-shaped slice is fixedly connected to a connecting rod, the bottom of the connecting rod is fixedly connected to the bottom of the first toothed disc, and the outer side of the arc-shaped slice slides along the inner wall of the cultivation cylinder.

[0015] With this arrangement, the rotation of the rotating drum drives the second toothed disc to rotate, and the rotation of the second toothed disc drives the first toothed disc to rotate. Since the arc-shaped slice is fixed to the first toothed disc, the first toothed disc will drive the arc-shaped slice to rotate along the inner wall of the cultivation drum, thereby cutting off the roots of the seedlings adhered to the inner wall of the cultivation drum by the soil, thereby making it safer and faster to remove the cultivated seedlings, avoiding damage to the seedlings, and helping to improve the survival rate of seedling transplantation and planting.

[0016] As a preferred embodiment of the present invention, evenly distributed rake teeth are fixedly connected to the inner middle portion of the arc-shaped slice.

[0017] Through this setting, the arc-shaped slices drive the rake teeth to rotate synchronously along the inner wall of the cultivation tube, which is conducive to scraping and loosening the edges of the soil layer, thereby allowing water or nutrient solution to quickly penetrate into the soil and root system, which is beneficial to improving cultivation efficiency.

[0019] Through this setting, the push plate and the mesh plate are used to stably support the bottom of the soil layer, and the mesh plate is helpful to reduce the contact area between the soil layer and the push plate, so that when the water collection tray drives the push plate to lift the seedlings in the soil layer upward for removal, it is faster and more convenient, making it easy to remove the seedlings.

[0020] As a preferred embodiment of the present invention, a water collecting trough is embedded in the interior of the water collecting tray, a guide groove is embedded on the top of the tray, a guide hole is opened on the guide groove, the guide hole is connected to the water collecting trough, and a guide pipe is fixedly connected to the side wall of the water collecting tray.

[0021] Through this setting, after spraying and watering the seedlings, excess water or nutrient solution will fall into the diversion trough and enter the water collection trough through the diversion hole, and then be discharged and collected through the diversion pipe, where the diversion pipe is connected to the external elastic hose, and the elastic hose is connected to the external water tank, which facilitates the diversion and collection of water resources and can be used again for the next irrigation to avoid waste.

[0022] As a preferred embodiment of the present invention, the four corners of the top of the water collecting tray are fixedly connected with sliding rods, the tray is provided with sliding holes, the sliding rods are slidably connected to the sliding holes, and the top of the sliding rods is fixedly connected with positioning blocks, which are placed on the tray.

[0023] Through this arrangement, the stability of the connection structure between the water collecting tray and the tray is effectively improved. The water collecting tray is used to collect and divert excess water or nutrient solution when watering on each layer of trays, avoiding waste. Moreover, when the cultivated seedlings need to be taken out from the culture tube, the tray of the lowest layer is moved onto the base. At this time, the water collecting tray contacts the base. The tray that continues to move downward will drive the sliding rod and the push rod to slide upward, and then push the push plate upward, so that the push plate lifts the soil layer and seedlings, facilitating faster removal of the seedlings. Then, the tray of the upper layer moves downward to drive the water collecting tray to contact the tray of the next layer. The tray that continues to move drives the push plate to lift the soil layer upward, and so on, thereby facilitating the rapid removal of the seedlings on each layer of trays. It is convenient and flexible to use.

DETAILED DESCRIPTION

[0027] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0028] The structure of the present invention is described in detail below with reference to the accompanying drawings.

[0029] refer to Figures 1 to 8 As shown, an embodiment of the present invention provides a cultivation device for forest seedling cultivation, including a base 1, wherein the four corners of the base 1 are fixedly connected with support rods 101, and the tops of the support rods 101 are fixedly connected with support plates 102, and two screw rods 2 are connected between the base 1 and the support plate 102 through bearings, and a tray 5 is installed between the screw rods 2 through a telescopic member, and a rotating rod 4 passes through the trays 5, and the two ends of the rotating rod 4 are respectively connected to the base 1 and the support plate 102 through bearings, and the interior of the tray 5 is fixedly connected with a cultivation tube 6 by bolts, and a ring cutting piece is slidably connected to the inner wall of the cultivation tube 6, and the ring cutting piece includes an arc slice 8, and the screw rod 2 can drive the arc slice 8 to rotate along the inner wall of the cultivation tube 6 through the rotating rod 4, and a water collecting tray 7 is slidably inserted into the bottom of the tray 5.

[0030] The above scheme is adopted: the cooperation between the screw rod 2 and the telescopic part can drive multiple trays 5 to adjust the height of the whole, and the water collecting tray 7 is used to guide and transport the excess water sprayed during the cultivation process to avoid waste. The cooperation between the screw rod 2, the rotating rod 4, the telescopic part and the ring cutting part facilitates the intermittent rotation of the arc slice 8 along the inner wall of the cultivation tube 6, and then facilitates the intermittent cutting of the roots of the seedlings that are excessively adhered to the inner wall of the cultivation tube 6, avoiding root damage when the seedlings are removed, and the water collecting tray 7 can also lift the soil layer and the seedlings upward when the seedlings are removed, thereby facilitating the rapid and safe removal of the seedlings after cultivation, avoiding damage to the seedlings during removal, and helping to improve the survival rate of seedling transplantation and planting, thereby effectively improving the cultivation efficiency and work efficiency.

[0031] Specifically, the four corners of the tray 5 are slidably mounted on the support rod 101, and both ends of the tray 5 are mounted on the screw rod 2. The tops of the two screw rods 2 are respectively fixed with a main gear 201 and a slave gear 204. A toothed belt 203 is connected between the main gear 201 and the slave gear 204. A motor 202 is fixedly installed on the top of the support plate 102, and the output end of the motor 202 is fixedly connected to the central axis of the main gear 201.

[0032] The above solution is adopted: the toothed belt 203 is used to drive the main gear 201 and the slave gear 204 to rotate synchronously in the same direction, and then drive the two screw rods 2 to rotate synchronously, and then drive the tray 5 on the telescopic part to perform overall height adjustment movement, making the cultivation rack easy to use.

[0033] Specifically, the telescopic part includes a telescopic long rod 302, a telescopic block 3 is threadedly sleeved on the screw rod 2, a support block 103 is fixedly connected to the top of the base 1, and a telescopic short rod 301 is hinged on the support block 103 and the telescopic block 3. The telescopic long rod 302 is hinged between the telescopic short rods 301. Several telescopic long rods 302 are provided and are hingedly connected to each other. The inner middle part of the telescopic long rod 302 is hingedly connected to the side wall of the tray 5 through a pin.

[0034] The above solution effectively improves the stability of the connection structure between the telescopic part and the screw rod 2. When the motor 202 drives the screw rod 2 to rotate, it drives the telescopic block 3 to move linearly along the screw rod 2, and then drives the telescopic long rod 302, the telescopic short rod 301 and the tray 5 to extend upward and retract downward, thereby realizing the height adjustment between the trays 5. The operation is flexible and convenient, and easy to use.

[0035] Specifically, a gear ring 401 is fixedly sleeved on the upper end of the rotating rod 4, the main gear 201 is meshed with the gear ring 401, the tray 5 is connected to a rotating drum 9 through a bearing, the rotating rod 4 is inserted into the rotating drum 9, and limiting grooves 402 are provided on both sides of the rotating rod 4. A limiting block 901 is fixedly connected to the inner wall of the rotating drum 9, and the limiting block 901 is inserted into the limiting groove 402.

[0036] The above scheme is adopted: through the meshing transmission principle of the main gear 201 and the gear ring 401, when the screw rod 2 drives the main gear 201 to rotate, the gear ring 401 and the rotating rod 4 can be driven to rotate synchronously. The stability of the rotating drum 9 during operation is guaranteed by the limit block 901 and the limit groove 402, so that the tray 5 will not rotate with the rotating drum 9, and the rotating drum 9 will move up and down with the tray 5 while rotating.

[0037] Specifically, a second toothed disc 902 is fixedly connected to the bottom side wall of the rotating cylinder 9, and the bottom of the tray 5 corresponding to the cultivation cylinder 6 is connected to the first toothed disc 803 through a bearing. The second toothed disc 902 and the adjacent first toothed disc 803 are meshed and connected, and the first toothed discs 803 are meshed and connected with each other. The bottom of the arc-shaped slice 8 is fixedly connected to a connecting rod 801, and the bottom of the connecting rod 801 is fixedly connected to the bottom of the first toothed disc 803. The outer side of the arc-shaped slice 8 slides along the inner wall of the cultivation cylinder 6.

[0038] The above-mentioned solution is adopted: the rotation of the rotating drum 9 drives the second toothed disc 902 to rotate, and the rotation of the second toothed disc 902 drives the first toothed disc 803 to rotate. Since the arc-shaped slice 8 is fixed to the first toothed disc 803, the first toothed disc 803 will drive the arc-shaped slice 8 to rotate along the inner wall of the cultivation cylinder 6, so that the roots of the seedlings adhered to the inner wall of the cultivation cylinder 6 by the soil are cut off, and then the cultivated seedlings are taken out more safely and quickly, avoiding damage to the seedlings and helping to improve the survival rate of seedling transplantation and planting.

[0039] Specifically, evenly distributed rake teeth 802 are fixedly connected to the inner middle portion of the arc-shaped slice 8 .

[0040] Adopting the above scheme: when the arc-shaped slice 8 drives the rake teeth 802 to rotate synchronously along the inner wall of the cultivation tube 6, it is beneficial to scrape and loosen the edge of the soil layer, so that water or nutrient solution can quickly penetrate into the soil and root system, which is beneficial to improve the cultivation efficiency.

[0041] Specifically, the bottom of the cultivation tube 6 is slidably connected to a push plate 703, the top of the push plate 703 is fixedly connected to a grid plate 704, the bottom of the push plate 703 is fixedly connected to a push rod 702, the push rod 702 is fixedly connected to the water collecting tray 7, and the arc-shaped slices 8 and the rake teeth 802 both slide along the side wall of the push plate 703.

[0042] The above-mentioned solution is adopted: the push plate 703 and the mesh plate 704 are used to stably support the bottom of the soil layer, and the mesh plate 704 is conducive to reducing the contact area between the soil layer and the push plate 703, so that when the water collection tray 7 drives the push plate 703 to lift the seedlings in the soil layer upward for removal, it is faster and more convenient, making it easy to remove the seedlings.

[0043] Specifically, a water collecting trough 701 is embedded in the interior of the water collecting tray 7, a guide groove 501 is embedded on the top of the tray 5, a guide hole 502 is opened on the guide groove 501, and the guide hole 502 is connected to the water collecting trough 701, and a guide pipe 707 is fixedly connected to the side wall of the water collecting tray 7.

[0044] Adopting the above scheme: after spraying and watering the seedlings, the excess water or nutrient solution will fall into the diversion groove 501 and enter the water collection tank 701 through the diversion hole 502, and then be discharged and collected through the diversion pipe 707, wherein the diversion pipe 707 is connected to the external elastic hose, and the elastic hose is connected to the external water tank, which facilitates the diversion and collection of water resources and can be reused for the next irrigation to avoid waste.

[0045] Specifically, the four corners of the top of the water collecting tray 7 are fixedly connected with sliding rods 705, and a sliding hole 503 is opened on the tray 5. The sliding rod 705 is matched with the sliding hole 503 and is slidably connected. The top of the sliding rod 705 is fixedly connected with a positioning block 706, and the positioning block 706 is placed on the tray 5.

[0046] The above scheme is adopted: the stability of the connection structure between the water collecting tray 7 and the tray 5 is effectively improved. The water collecting tray 7 is used to collect and divert excess water or nutrient solution when watering on each layer of tray 5, avoiding waste. Moreover, when it is necessary to take out the cultivated seedlings from the culture tube, the tray 5 of the bottom layer is moved onto the base 1. At this time, the water collecting tray 7 contacts the base 1. The tray 5 that continues to move downward will drive the sliding rod 705 and the push rod 702 to slide upward, and then push the push plate 703 upward, so that the push plate 703 lifts the soil layer and the seedlings, facilitating faster removal of the seedlings. Immediately afterwards, the tray 5 of the upper layer moves downward to drive the water collecting tray 7 to contact the tray 5 of the next layer. The tray 5 that continues to move drives the push plate 703 to lift the soil layer upward, and so on, thereby facilitating the rapid removal of the seedlings on each layer of tray 5, which is convenient and flexible to use.

[0047] Working principle of the present invention: During use, after the motor 202 is started, it drives the two screw rods 2 to rotate synchronously. The telescopic block 3 will move in a straight line along the screw rod 2 due to the action of the thread, and then drive the telescopic long rod 302 and the telescopic short rod 301 to extend or contract, so as to adjust the height of the tray 5. The guide groove 501 on the top of the tray 5 collects excess water or nutrient solution during watering, and enters the water collection tank 701 through the guide hole 502. The liquid in the water collection tank 701 is discharged and collected through the guide pipe 707, and can be connected to an external water tank for reuse to avoid waste.

[0048] At the same time, the rotating rod 4 drives the rotating drum 9 to rotate synchronously through the limiting groove 402 and the limiting block 901, so that the second toothed disc 902 drives the first toothed disc 803 to rotate, and the first toothed disc 803 drives the arc-shaped slice 8 and the rake teeth 802 to rotate along the inner wall of the cultivation cylinder 6, cutting off the roots adhered to the inner wall of the cultivation cylinder 6 and loosening the soil, thereby achieving intermittent cutting of the roots and the cultivation cylinder 6, facilitating the safe removal of the seedlings in the later stage, and also facilitating the rapid penetration of water or nutrient solution into the soil and root system, which is beneficial to improving the cultivation efficiency.

[0049] When the seedlings need to be taken out from the cultivation tube 6, the tray 5 on the bottom layer moves to the base 1. At this time, the water collecting tray 7 contacts the base 1. The tray 5 that continues to move downward will drive the slide bar 705 and the push rod 702 to slide upward, and then push the push plate 703 and the grid plate 704 to move upward, lifting the soil layer and the seedlings so that they can be taken out quickly. Subsequently, the tray 5 on the upper layer moves downward to drive the water collecting tray 7 to contact the tray 5 on the next layer, and the above process is repeated until all the seedlings are taken out.
