Description

Technical Field

[0001] The invention relates to the technical field of forest seedling cultivation, and in particular to a forest seedling cultivation device. Background Art

[0002] Seedling cultivation means the cultivation of seedlings. Its original meaning refers to the cultivation of seedlings in a nursery, hotbed or greenhouse in preparation for transplanting into the land for planting. It can also refer to the stage when various organisms are artificially protected when they are small until they can survive independently. Seedling cultivation is a labor-intensive, time-consuming and highly technical job.

[0003] A Chinese patent with application number CN202210895213.X discloses an intelligent seedling raising device for municipal gardens, in which the device body is longitudinally fixedly installed at the top center position of the mounting base, and a seedling raising board is transversely installed at the inner center position of the device body, and hydraulic cylinders are fixedly installed on both sides of the inner center position of the mounting base, and piston rods are added to the telescopic ends of the tops of the hydraulic cylinders, and the tops of the piston rods extend upward through the outer walls of the mounting base and the device body, and the tops of the piston rods are connected to the seedling raising boards through stabilizing devices. The hydraulic cylinder in the above patent drives the connected stabilizing device and seedling raising board to rise and fall through the piston rod, and the sliding rods connected on both sides of the seedling raising board slide up and down in the slide groove. In this way, it is convenient to adjust the space for seedling raising, and avoid the phenomenon of insufficient development of seedlings due to insufficient living space after growth.

[0048] like Figures 1 to 15 As shown, a forest seedling raising device of the present invention comprises: a seedling raising box 1, a seedling raising mechanism 2 for raising forest seedlings, and a spraying mechanism 3 for watering the seedlings;

[0049] The seedling raising mechanism 2 comprises: a seedling raising basin 21 for raising seedlings, the seedling raising basin 21 is composed of a movable basin body 211 and a fixed basin body 212, the movable basin body 211 and the fixed basin body 212 have the same shape, and the bottoms of the movable basin body 211 and the fixed basin body 212 are both provided with a semicircular opening, when in use, the movable basin body 211 and the fixed basin body 212 are docked together to form the seedling raising basin 21, at which time seedling raising work can be carried out, a lifting component 22 for adjusting the height of the seedling raising basin 21 according to the height of the seedlings, a rotating component 23 for rotating the seedlings to the spraying mechanism 3 when spraying the seedlings, and a removal component 24 for removing the seedlings from the seedling raising basin 21 when transplanting the seedlings;

[0050] When raising seedlings, soil is placed in the seedling pot 21, and the seeds of the trees are placed in the soil for seedling raising. There are multiple seedling pots 21, and they are distributed in a circular array in the inner cavity of the seedling box 1, so that multiple seedlings can be cultivated at the same time. The multiple seedling pots 21 can be watered separately through the spraying mechanism 3 to ensure the normal growth of the seedlings.

[0051] The removal assembly 24 includes: a moving unit 241 for driving the movable basin body 211 to move, and an ejection unit 242 for ejecting the seedlings from the seedling basin 21; the moving unit 241 includes: an installation box 2411, the installation box 2411 is located inside the seedling box 1, the seedling basin 21 is arranged on the top of the installation box 2411, and a plurality of seedling basins 21 are arranged in a circular array with the top center of the installation box 2411 as the central axis, the bottom of the movable basin body 211 is attached to the top of the installation box 2411, and the fixed basin body 2 A driving gear 2413 fixedly mounted on the top of the installation box 2411 and rotatably mounted on the bottom of the inner cavity of the installation box 2411, a power source 2412 driving the driving gear 2413 to rotate, an arc groove provided on the side wall of the driving gear 2413, a limiting groove provided on the top of the installation box 2411, a connecting rod 2414 penetrating the inner cavity of the arc groove and the limiting groove and fixedly mounted on the side wall of the movable basin body 211, and a guide member 2415 guiding the connecting rod 2414 when it moves;

[0052] By starting the power source 3 2412, the driving gear 2413 is driven to rotate. Due to the setting of the arc groove, the driving gear 2413 drives the linkage rod 2414 to move. Through the setting of the limiting groove and the guide member 2415, the linkage rod 2414 can be limited and guided, so that the linkage rod 2414 keeps moving in a straight line direction.

[0053] When the seedlings need to be transplanted, the power source 3 2412 is started to drive several connecting rods 2414 to move inward synchronously, thereby driving several movable basin bodies 211 to move inward synchronously, so that the movable basin body 211 is separated from the fixed basin body 212, thereby facilitating the removal of the seedlings and the soil around their roots, thereby improving the transplanting efficiency.

[0054] It is to be added here that the power source three 2412 is preferably: a motor.

[0055] The guide member 2415 includes: a guide groove provided at the bottom of the inner cavity of the installation box 2411, a guide block 24151 fixedly installed at the bottom end of the linkage rod 2414 and sliding in the inner cavity of the guide groove, and a guide rod 24152 penetrating and installed on the side wall of the guide block 24151, and both ends of the guide rod 24152 are fixedly installed on the inner wall of the guide groove;

[0056] When the connecting rod 2414 moves, it can drive the guide block 24151 to slide in the inner cavity of the guide groove. Since the guide groove and the limit groove are both straight grooves, the connecting rod 2414 can maintain movement in a straight line. Through the setting of the guide rod 24152, it can prevent the guide block 24151 from detaching from the inner cavity of the guide groove, thereby ensuring the stability of the connecting rod 2414 during movement.

[0057] The ejection unit 242 includes: a threaded shaft 2422 rotatably installed on the inner wall of the installation box 2411, a linkage gear 2421 fixedly sleeved on the outer edge of the threaded shaft 2422 and meshing with the driving gear 2413, a movable plate 2423 threadedly connected to the threaded shaft 2422, and a movable rod 2424 fixedly installed on the top of the movable plate 2423, the top of the movable rod 2424 passes through the top of the installation box 2411, and passes through the semicircular opening inner cavity at the bottom of the movable basin body 211 and the fixed basin body 212, a movable seat 2425 fixedly installed on the top of the movable rod 2424, and located in the seedling basin 21.

[0058] When the movable basin body 211 is separated from the fixed basin body 212, the driving gear 2413 drives the connecting gear 2421 to rotate, the connecting gear 2421 drives the threaded shaft 2422 to rotate, the threaded shaft 2422 drives the movable plate 2423 to move upward along the axial direction of the threaded shaft 2422, the movable plate 2423 drives the movable rod 2424 to move upward, and the movable rod 2424 drives the movable seat 2425 to move upward, thereby pushing the seedlings and the soil at their roots upward to the outside of the seedling pot 21, thereby facilitating the removal of the seedlings and the soil at their roots, and further improving the transplanting efficiency.

[0059] Since the movable seat 2425 moves upward when the movable basin body 211 is separated from the fixed basin body 212 , it is easier to push the seedlings and the soil around their roots out of the seedling pot 21 .

[0060] In the present application, by setting up the removal component 24, the movable seat 2425 can move upward while the movable basin body 211 is separated from the fixed basin body 212, pushing the seedlings and the soil around their roots out to the outside of the seedling pot 21, thereby separating the seedlings and the soil around their roots from the seedling pot 21, making it convenient for the staff to take out the seedlings and the soil around their roots for transplanting, solving the problem that the existing seedling raising device needs to manually pull the seedlings out of the seedling raising board when transplanting after the seedling raising is completed, which easily causes the seedlings to be injured and reduces the survival rate of the seedlings after transplanting.

[0061] It is added here that a cavity is opened on the movable seat 2425, soil is accumulated on the top of the movable seat 2425, and the outer edge of the movable seat 2425 is in contact with the inner walls of the movable basin body 211 and the fixed basin body 212.

[0062] The lifting assembly 22 includes: a fixing plate fixedly installed on the inner wall of the seedling box 1, a threaded rod 222 rotatably installed on the side wall of the fixing plate, a power source 221 for driving the threaded rod 222 to rotate, a threaded tube 223 threadedly connected to the threaded rod 222 and rotatably installed at the bottom center of the installation box 2411, and a limiting unit 224 for limiting the threaded tube 223 when it moves.

[0063] As the seedlings grow in height during the seedling raising process, the growth space of the seedlings needs to be adjusted. At this time, the power source 221 is started to drive the threaded rod 222 to rotate, and the threaded rod 222 drives the threaded tube 223 to move. Under the limiting action of the limiting unit 224, the threaded tube 223 moves along the axial direction of the threaded rod 222, and the threaded tube 223 drives the installation box 2411 to move, thereby driving the seedling raising basin 21 to move. By adjusting the height of the seedling raising basin 21, the present application facilitates the adjustment of the seedling raising space to avoid the phenomenon of insufficient development of the seedlings due to insufficient living space after they grow up.

[0064] It is to be added here that the power source 221 is preferably: a motor.

[0065] The limiting unit 224 includes: a fixed tube 2241 fixedly installed on the top of the fixed plate and sleeved on the outer edge of the threaded tube 223, a slide groove opened on the inner wall of the fixed tube 2241, and a limiting strip 2242 fixedly installed on the side wall of the threaded tube 223 and sliding in the inner cavity of the slide groove.

[0066] The limiting strip 2242 slides in the inner cavity of the slide groove, so that the threaded tube 223 can be guided and limited to prevent the threaded tube 223 from rotating with the threaded rod 222, thereby allowing the threaded tube 223 to move along the axial direction of the threaded rod 222.

[0067] The rotating assembly 23 includes: a driving gear 232 rotatably mounted on the side wall of the fixed plate, a power source 231 for driving the driving gear 232 to rotate, a driven gear 233 rotatably mounted on the outer edge of the fixed tube 2241 and meshing with the driving gear 232, and a telescopic rod 234 fixedly mounted between the top of the driven gear 233 and the bottom of the installation box 2411.

[0068] When the seedlings need to be watered, the power source 231 is started to drive the driving gear 232 to rotate, the driving gear 232 drives the driven gear 233 to rotate, the driven gear 233 drives the telescopic rod 234 to rotate, and the telescopic rod 234 drives the installation box 2411 to rotate, thereby driving the seedling pot 21 to rotate, so that the seedlings rotate to the spray mechanism 3 in turn. At this time, the spray mechanism 3 can be started to spray the seedlings, and multiple seedling pots 21 can be watered separately through the spray mechanism 3, thereby ensuring the normal growth of the seedlings.

[0069] Since the seedling raising pots 21 are provided separately, the spraying amount for each seedling raising pot 21 is the same, thereby avoiding mutual influence between the seedlings and making the growth conditions of the seedlings consistent.

[0070] In addition, when the seedlings need to be transplanted, each seedling can be rotated to the door 4 of the nursery box 1 by the rotating assembly 23, so that the staff can take out the seedlings easily, thereby improving the transplanting efficiency.

[0071] It is to be added here that the second power source 231 is preferably: a motor.

[0072] The spray mechanism 3 includes: a nozzle 31 for spraying the seedlings, a delivery component 32 for delivering water to the nozzle 31, an adsorption and shielding component 33 for absorbing the water seeping out of the seedling soil and shielding the nozzle 31, and a recovery component 34 for collecting and recovering the excess water sprayed by the nozzle 31 after the nozzle 31 is shielded;

[0073] The conveying assembly 32 includes: a horizontal plate fixedly installed on the inner wall of the seedling box 1, a water tank 321 fixedly installed on the top of the horizontal plate, and a water pump 322 that transports water in the water tank 321 to the nozzle 31. An inlet pipe is fixedly installed between the nozzle 31 and the water pump 322. The water pump 322 is fixedly installed on the top of the horizontal plate, and a water outlet pipe is plugged and installed between the water pump 322 and the water tank 321.

[0074] When spraying the seedlings, by starting the water pump 322, the water in the water tank 321 can enter the water pump 322 through the outlet pipe, and then enter the nozzle 31, and be sprayed in the seedling pot 21 through the nozzle 31, so that the water enters the soil. Since the roots of the seedlings are located at the bottom of the soil, the soil needs to be soaked, and in order to maintain the moisture content in the soil, the soil needs to be sprayed with a certain amount of water regularly to meet the production needs of the seedlings.

[0075] Since the seedling raising pots 21 are provided separately, the spraying amount for each seedling raising pot 21 is the same, thereby avoiding mutual influence between the seedlings and making the growth conditions of the seedlings consistent.

[0076] As a further extension of the present application, since the soil needs to be soaked, it is easy to have a large amount of watering. When the amount of watering is large, it is easy to cause water accumulation in the seedling pot 21, resulting in a decrease in seedling vitality and affecting growth. If the roots are immersed in water for a long time, it will cause root lack of oxygen and root rot, and severe cases will cause death. Therefore, an adsorption shielding component 33 is provided in the present application.

[0077] The adsorption shielding component 33 includes: an adsorption unit 331 for absorbing moisture seeping from the soil of seedlings, and a shielding unit 332 for shielding the nozzle 31; the adsorption unit 331 includes: a mounting shell 3311 fixedly mounted on the bottom of the inner cavity of the mounting box 2411, an adsorption expansion body 3312 fixedly mounted on the top of the inner cavity of the mounting shell 3311, a filter plate 3313 fixedly mounted on the top of the movable seat 2425, and a retractable tube 3314 plugged and installed on the bottom of the movable seat 2425 and the top of the mounting shell 3311.

[0078] By setting the filter plate 3313 on the top of the movable seat 2425, the water seeping from the bottom of the soil can flow into the cavity of the movable seat 2425, and enter the installation shell 3311 through the telescopic tube 3314, and then be absorbed by the adsorption expansion body 3312, so that the water seeping from the soil can be discharged and absorbed in time, preventing water from accumulating in the seedling basin 21 for a long time, causing water to accumulate in the seedling basin 21, reducing the vitality of the seedlings and affecting their growth.

[0079] It should be added here that the adsorption expansion body 3312 is made of porous water-absorbing expansion material. The pores of the adsorption expansion body 3312 form numerous tiny capillary channels. According to the principle of capillary phenomenon, the water flowing into the mounting shell 3311 is absorbed by the adsorption expansion body 3312, and the water seeping out of the soil can be discharged and absorbed in time to prevent water from accumulating in the seedling pot 21 for a long time, resulting in water accumulation in the seedling pot 21, which reduces the vitality of the seedlings and affects their growth.

[0080] In addition, when the moisture content in the soil decreases, the water in the adsorption expansion body 3312 will evaporate and enter the cavity of the movable seat 2425 through the telescopic tube 3314, and then enter the soil, thereby providing moisture from the bottom of the soil, making it easier for the roots of the seedlings to absorb moisture, further ensuring the normal growth of the seedlings.

[0081] The shielding unit 332 includes: a cylinder 3321 rotatably installed at the bottom center of the horizontal plate, a disk 3322 fixedly installed at the bottom end of the cylinder 3321, a spray opening 3323 opened on the side wall of the disk 3322, there are several spray openings 3323, and they correspond to the positions of the seedling pots 21 one by one, a mounting groove 3324 opened on the side wall of the disk 3322 and interconnected with the spray opening 3323, a baffle 3325 movably installed in the inner cavity of the mounting groove 3324 and capable of sealing the spray opening 3323, a moving part 3326 for driving the baffle 3325 to move, and a linkage part 3327 for the disk 3322 to rotate synchronously with the mounting box 2411.

[0082] When the adsorption expansion body 3312 absorbs water and expands, it can drive the moving part 3326 to operate. The moving part 3326 includes: an air bag 33261 fixedly installed between the bottom of the inner cavity of the mounting shell 3311 and the bottom of the adsorption expansion body 3312, a piston 33263 fixedly installed on one side of the baffle 3325, a reset spring 33264 that drives the baffle 3325 to reset, and an air guide tube 33262 that connects the air bag 33261 with the inner cavity of the mounting groove 3324; so that when the adsorption expansion body 3312 absorbs water and expands, the air bag 33261 can be squeezed to compress the air bag 33261. When the air bag 33261 is compressed, the air inside it is squeezed out and enters the mounting groove 3324 through the air guide tube 33262. Cavity, due to the increase of air pressure in the inner cavity of the mounting groove 3324, the piston 33263 is pushed to move under the action of air pressure, and the piston 33263 drives the baffle 3325 to move, and drives the reset spring 33264 to stretch. The baffle 3325 moves, and the spray opening 3323 can be blocked and closed. At this time, the water sprayed by the sprinkler head 31 is blocked by the baffle 3325 and can no longer flow into the seedling pot 21. On the one hand, the seedlings can be protected to prevent the soil at the top of the seedling pot 21 from being washed to the outside of the seedling pot 21 when the amount of watering is large, causing the seedlings to fall over and break. On the other hand, it can prevent the problem that when the amount of watering is large, the seedling pot 21 is easily watered, resulting in a decrease in seedling vitality and affecting growth.

[0083] When the spraying is stopped, the water in the adsorption expansion body 3312 will evaporate, so that the adsorption expansion body 3312 is dehydrated and restored, so that the adsorption expansion body 3312 gradually reduces the squeezing of the airbag 33261. Since the airbag 33261 itself has a certain elasticity, it can exert a certain squeezing force on the adsorption expansion body 3312, thereby further driving the adsorption expansion body 3312 to dehydrate and restore;

[0084] When the airbag 33261 gradually recovers, the gas in the inner cavity of the installation groove 3324 can be sucked into the airbag 33261. When the air pressure in the inner cavity of the installation groove 3324 gradually decreases, the piston 33263 can be driven to reset through the elastic force of the reset spring 33264. The piston 33263 squeezes the air in the inner cavity of the installation groove 3324, so that the air enters the airbag 33261 through the air guide tube 33262, and then the baffle 3325 can be driven to reset, so that the baffle 3325 no longer blocks the spray opening 3323, and the next spraying can be prepared.

[0085] Furthermore, the squeezing effect of the piston 33263 on the air can accelerate the entry of air into the inner cavity of the airbag 33261, thereby assisting the recovery of the airbag 33261. Due to the auxiliary effect on the recovery of the airbag 33261, the squeezing force of the airbag 33261 on the adsorption expansion body 3312 becomes larger, thereby improving the efficiency of the dehydration recovery of the adsorption expansion body 3312.

[0086] In the present application, the water absorption and expansion of the adsorption expansion body 3312 can, on the one hand, timely discharge and absorb the water seeping from the soil to prevent the water from accumulating in the seedling pot 21 for a long time, resulting in water accumulation in the seedling pot 21, which reduces the vitality of the seedlings and affects their growth. On the other hand, it can drive the baffle 3325 to move and block and close the spray opening 3323. At this time, the water sprayed by the nozzle 31 is blocked by the baffle 3325 and cannot flow into the seedling pot 21, thereby preventing the seedlings from being easily accumulated in the seedling pot 21 when the amount of watering is large, resulting in a decrease in the vitality of the seedlings and affecting their growth. The problem of affecting growth; through the dehydration recovery of the adsorption expansion body 3312, on the one hand, when the moisture content in the soil decreases, the water in the adsorption expansion body 3312 will evaporate and enter the cavity of the movable seat 2425 through the telescopic tube 3314, and then enter the soil, thereby providing moisture from the bottom of the soil, making it easier for the roots of the seedlings to absorb moisture, further ensuring the normal growth of the seedlings, and on the other hand, it can drive the baffle 3325 to reset, so that the baffle 3325 no longer has a blocking effect on the spray opening 3323, and can be prepared for the next spraying.

[0087] In the present application, the compression of the airbag 33261 drives the baffle 3325 to move, and the spray opening 3323 can be blocked and closed. At this time, the water sprayed by the nozzle 31 is blocked by the baffle 3325 and can no longer flow into the nursery pot 21. On the one hand, the seedlings can be protected to prevent the soil at the top of the nursery pot 21 from being washed to the outside of the nursery pot 21 when the amount of watering is large, causing the seedlings to fall and break. On the other hand, it can prevent the problem that water accumulates in the nursery pot 21 when the amount of watering is large, causing the seedling vitality to decrease and affecting the growth. Through the recovery of the airbag 33261, on the one hand, the gas in the inner cavity of the installation groove 3324 can be sucked into the airbag 33 261, when the air pressure in the inner cavity of the installation groove 3324 gradually decreases, the piston 33263 can be reset through the elastic force of the reset spring 33264, and the air in the inner cavity of the installation groove 3324 is squeezed by the piston 33263, so that the air enters the airbag 33261 through the air guide tube 33262, and then the baffle 3325 can be reset, so that the baffle 3325 no longer has a blocking effect on the spray opening 3323, and can prepare for the next spraying. On the other hand, since the airbag 33261 itself has a certain elasticity, it can exert a certain squeezing force on the adsorption expansion body 3312, thereby further driving the adsorption expansion body 3312 to dehydrate and recover.

[0088] It is to be added that, by designing the spray openings 3323 on the disc 3322 to correspond one to one with the nursery pots 21, other seedlings will not be affected during spraying.

[0089] The linkage 3327 includes: a connecting tube 33271 fixedly installed at the bottom center of the disc 3322 , and a connecting rod 33272 movably installed in the inner cavity of the connecting tube 33271 and fixedly installed at the top center of the installation box 2411 .

[0090] Since the spray openings 3323 provided on the disc 3322 correspond one-to-one with the seedling basin 21, the disc 3322 and the seedling basin 21 need to rotate synchronously. Since the rotation of the mounting box 2411 can drive the seedling basin 21 to rotate, the connecting rod 33272 can be driven to rotate, and the connecting rod 33272 drives the connecting tube 33271 to rotate, thereby driving the disc 3322 to rotate, thereby achieving synchronous rotation of the disc 3322 and the seedling basin 21.

[0091] Therefore, when the nursery pot 21 rotates to be directly below the spray head 31 , the spray opening 3323 moves to be aligned with the spray head 31 , so that the seedlings in the nursery pot 21 can be sprayed conveniently.

[0092] The recovery component 34 includes: a collecting groove 343 opened at the center of the top of the disc 3322, a guide groove 344 opened at the top of the disc 3322, the guide groove 344 is respectively interconnected with the inner cavity of the collecting groove 343 and the spray opening 3323. When the spray opening 3323 is blocked by the baffle 3325, excess water can flow into the inner cavity of the guide groove 344 along the surface of the baffle 3325, and flow into the inner cavity of the collecting groove 343 through the guide groove 344 for collection, a water pump 342 fixedly installed on the top of the horizontal plate, a return pipe 341 plugged installed at the bottom of the water pump 342, and a guide pipe 345 plugged installed between the water pump 342 and the water tank 321.

[0093] By starting the second water pump 342, the water in the inner cavity of the collecting tank 343 can be sucked through the return pipe 341 and enter the water tank 321 through the guide pipe 345, so as to facilitate the recycling of water and save water resources.

[0094] It should be added here that the bottom of the inner cavity of the guide groove 344 is inclined, and the bottom of the inner cavity of the guide groove 344 is from high to low along the direction from the spray opening 3323 to the collection groove 343, so as to facilitate the water flow blocked by the baffle 3325 to be introduced into the inner cavity of the collection groove 343 for collection.

[0095] The side wall of the nursery box 1 is hingedly provided with a box door 4, and the side wall of the box door 4 is fixedly provided with a visual window 5. When the seedlings need to be taken out of the nursery box 1, the box door 4 can be opened, and the visual window 5 can be provided to facilitate the staff to observe the growth status of the seedlings in the nursery box 1.
