Description

Technical Field

[0001] This invention relates to the field of agricultural seedling technology, specifically to a smart agricultural seedling device. Background Technology

[0002] Seedling cultivation refers to the process of nurturing seedlings until they can grow independently. It can also refer to the stage in which various microorganisms are artificially protected until they can survive independently. Traditional seedling cultivation is a labor-intensive, time-consuming, and technically demanding task. However, with the development of science and technology, smart agriculture has gradually entered the public eye. Compared with traditional agriculture, smart agriculture is more scientific and efficient.

[0003] Different seedling species have corresponding seedling cultivation methods, the most important of which are soilless seedling cultivation and soil seedling cultivation. Soilless seedling cultivation uses culture solution for seedling cultivation. Existing smart agricultural seedling cultivation devices often can only realize one seedling cultivation method. When changing the seedling species, it is often necessary to manually change the corresponding seedling rack or seedling pot, which involves a high degree of manual intervention and cannot further save human resources. Summary of the Invention

[0004] The purpose of this invention is to provide a smart agricultural seedling raising device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a smart agricultural seedling raising device, comprising a three-dimensional frame, a placement frame fixedly installed on the top of the three-dimensional frame, a placement seat placed on the inner side of the placement frame, a through hole opened in the center of the placement seat, and a cultivation mechanism fixedly installed on the three-dimensional frame.

[0006] The cultivation mechanism includes a mounting plate, which is fixedly mounted on a three-dimensional frame. A motor is fixedly mounted on the bottom of the mounting plate, and a lead screw is fixedly mounted on the output end of the motor. A lifting seat is threaded onto the outer wall of the lead screw. A sliding rod is fixedly mounted on the top of the mounting plate, and the top end of the sliding rod movably passes through the bottom of the lifting seat. A connecting shaft is rotatably connected to the inner wall of the lifting seat via a bearing. A cultivation cylinder is fixedly mounted on the outer wall of the connecting shaft. The cultivation cylinder is inverted, and a soil-holding groove is opened on the top of the cultivation cylinder. The cultivation cylinder is inserted into a through hole in the center of the placement seat. A worm gear is fixedly mounted on the outer wall of the connecting shaft. A support plate is fixedly mounted on the top of the mounting plate. A second motor is fixedly mounted on the top of the mounting plate, and a worm is fixedly mounted on the output end of the second motor. The outer wall of the worm is rotatably connected to the inner wall of the support plate via a bearing.

[0007] Furthermore, each of the placement base and the cultivation cylinder is provided in a number and is distributed at equal intervals on the placement frame. Each cultivation cylinder is a group, and the same group of cultivation cylinders is fixedly connected to the same connecting shaft. The left and right ends of the connecting shaft are rotatably connected to lifting seats through bearings.

[0008] Furthermore, a position sensor is fixedly mounted on the top of the mounting plate, and the position sensor is offset from the worm gear.

[0009] Furthermore, the placement base includes a water-permeable base and a water-permeable top cover. The water-permeable top cover is fixedly installed on the top of the water-permeable base. A water-guiding groove is provided on the top of the water-permeable base. The water-guiding groove is connected to the central through hole of the placement base. The water-permeable hole on the water-permeable base is smaller than the water-permeable hole on the water-permeable top cover.

[0010] Furthermore, a friction ring is fixedly sleeved on the outer wall of the connecting shaft, a guide rod is fixedly installed on the outer wall of the lifting seat, a friction ring is slidably sleeved on the outer wall of the guide rod, the friction ring is elastically connected to the lifting seat by a spring, an extension plate is fixedly installed at the bottom of the friction ring, and an inclined push plate is fixedly installed at the top of the mounting plate, the inclined push plate being located below the extension plate.

[0011] Furthermore, electric slide rails are fixedly installed on both the front and back of the three-dimensional frame, and a movable frame is fixedly installed on the movable end of the electric slide rail. A water pipe is fixedly installed on the top inner side of the movable frame, and a spray head is connected to the bottom of the water pipe.

[0012] Furthermore, dripping pipes are fixedly installed on the left and right outer walls of the mobile frame by pipe clamps. The bottom of the dripping pipe is connected to a dripper, and the top of both the water pipe and the dripping pipe is connected to a flexible hose, which is connected to the pipeline network inside the seedling greenhouse.

[0013] Furthermore, a soil recycling bin is placed inside the three-dimensional frame, and the soil recycling bin is located directly below the placement base. The bottom inner wall of the soil recycling bin is an inclined surface, and a filter screen is provided at the bottom of the soil recycling bin.

[0014] Furthermore, a sewage recovery chamber is provided below the soil recovery chamber. The sewage recovery chamber is placed on the ground, and the bottom inner wall of the sewage recovery chamber is shaped as high in the middle and low on both sides.

[0015] Furthermore, a partition plate is provided between the sewage recovery chamber and the soil recovery chamber. The partition plate is fixedly installed on the three-dimensional frame, and a limit baffle is fixedly installed on the back of the partition plate located at the rear. The limit baffle blocks the rear of the soil recovery chamber.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. After a group of seedlings is completed, simply turn on motor one to drive the lead screw to rotate, causing the lifting seat to move down, which in turn drives the connecting shaft to move down. After the worm gear and worm mesh, motor two drives the worm to rotate, causing the worm gear to rotate, which in turn drives the connecting shaft to rotate, turning the cultivation cylinder over. This is used to pour out the culture solution in the cultivation cylinder or the soil in the soil container, and then carry out the next round of seedling cultivation. There is no need to manually replace the cultivation cylinder.

[0018] 2. By setting up permeable bases and permeable top covers with different permeability rates, the sprayed water droplets can gradually seep into the placement base after falling onto it, and then flow from the water guide channel into the central through hole of the placement base, and then flow back to the seedlings, improving the water utilization rate. In addition, because the permeable base can also seep water, it can prevent a large amount of water from continuously submerging the roots of the seedlings, thereby preventing damage to the seedlings.

[0019] 3. Set up a soil recovery bin to catch the dumped soil. Utilize the inclination of the bottom of the soil recovery bin to allow the soil to slide along the inner wall of the bottom of the soil recovery bin. Then, it is washed into one side of the soil recovery bin by the dripping water, which makes it easier to collect the soil. Set up a filter screen to filter the water to prevent the soil recovery bin from overflowing and causing the soil to fall and splash everywhere. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Example 1

[0033] Please see Figures 1-7 The present invention provides a technical solution: a smart agricultural seedling raising device, including a three-dimensional frame 1, a placement frame 2 fixedly installed on the top of the three-dimensional frame 1, a placement seat 3 placed on the inner side of the placement frame 2, a through hole opened in the center of the placement seat 3, and a cultivation mechanism 4 fixedly installed on the three-dimensional frame 1.

[0034] The cultivation mechanism 4 includes a mounting plate 401, which is fixedly mounted on the three-dimensional frame 1. A motor 402 is fixedly mounted on the bottom of the mounting plate 401. A lead screw 403 is fixedly mounted on the output end of the motor 402. A lifting seat 405 is threaded onto the outer wall of the lead screw 403. A sliding rod 404 is fixedly mounted on the top of the mounting plate 401. The top end of the sliding rod 404 movably passes through the bottom of the lifting seat 405. A connecting shaft 406 is rotatably connected to the inner wall of the lifting seat 405 via bearings. A cultivation cylinder 4011 is fixedly mounted on the outer wall of the connecting shaft 406. The cultivation cylinder 4011 is inverted, and a soil-holding trough 5 is opened on its top. The cultivation cylinder 4011 is inserted into the through hole in the center of the placement seat 3. A worm gear 407 is fixedly mounted on the outer wall of the connecting shaft 406. A support plate 409 is fixedly mounted on the top of the mounting plate 401. A second motor 401 is fixedly mounted on the top of the mounting plate 401. 10. A worm gear 408 is fixedly installed at the output end of motor 2 4010. The outer wall of the worm gear 408 is rotatably connected to the inner wall of the support plate 409 through a bearing. By inserting the cultivation cylinder 4011 into the central through hole of the placement seat 3, a seedling box is formed. The cultivation cylinder 4011 is used to hold the culture solution, i.e., for soilless seedling cultivation. The soil holding trough 5 on the cultivation cylinder 4011 is used to hold the soil for normal cultivation. After a set of seedlings is completed, simply turn on motor 1 402 to drive the lead screw 403 to rotate, causing the lifting seat 405 to move down, which in turn drives the connecting shaft 406 to move down. After the worm wheel 407 meshes with the worm gear 408, motor 2 4010 drives the worm gear 408 to rotate, causing the worm wheel 407 to rotate, which in turn drives the connecting shaft 406 to rotate, turning the cultivation cylinder 4011 over to pour out the culture solution in the cultivation cylinder 4011 or the soil in the soil holding trough 5, and then carry out the next round of seedling cultivation.

[0035] There are 33 placement seats 3 and 33 cultivation cylinders 4011, which are evenly distributed on the placement frame 2. Every 9 cultivation cylinders 4011 form a group. The same group of cultivation cylinders 4011 is fixedly connected to the same connecting shaft 406. Multiple placement seats 3 and cultivation cylinders 4011 are set up to cultivate multiple seedlings at the same time. The left and right ends of the connecting shaft 406 are rotatably connected to lifting seats 405 through bearings, which support the connecting shaft 406 from the left and right ends to prevent the connecting shaft 406 from bending excessively.

[0036] A position sensor 24 is fixedly installed on the top of the mounting plate 401. The position sensor 24 is offset from the worm gear 407 and is used to detect the position of the worm gear 407, thereby determining that the worm gear 407 is engaged with the worm 408.

[0037] The placement base 3 includes a water-permeable base 301 and a water-permeable top cover 302. The water-permeable top cover 302 is fixedly installed on the top of the water-permeable base 301. A water-guiding groove 303 is provided on the top of the water-permeable base 301. The water-guiding groove 303 is connected to the central through hole of the placement base 3. The water-permeable holes on the water-permeable base 301 are smaller than the water-permeable holes on the water-permeable top cover 302. By setting water-permeable bases 301 and water-permeable top covers 302 with different water-permeability rates, the water droplets sprayed onto the placement base 3 can gradually seep into the placement base 3, and then flow from the water-guiding groove 303 into the central through hole of the placement base 3, and then flow back to the seedlings. This improves the water utilization rate. Also, because the water-permeable base 301 can also seep water, it can prevent a large amount of water from continuously submerging the roots of the seedlings, thereby preventing damage to the seedlings.

[0038] A friction ring 8 is fixedly sleeved on the outer wall of the connecting shaft 406. A guide rod 11 is fixedly installed on the outer wall of the lifting seat 405. A friction ring 9 is slidably sleeved on the outer wall of the guide rod 11. The friction ring 9 and the lifting seat 405 are elastically connected by a spring 12. An extension plate 10 is fixedly installed at the bottom of the friction ring 9. An inclined push plate 13 is fixedly installed at the top of the mounting plate 401. The inclined push plate 13 is located below the extension plate 10. When the inclined push plate 13 is in contact with the extension plate 10, the spring 12 pushes the friction ring 9 to press against the friction ring 8. The friction between the friction ring 8 and the friction ring 9 prevents the connecting shaft 406 from rotating easily. When the connecting shaft 406 can rotate, the inclined push plate 13 contacts the extension plate 10. At the same time, the inclined push plate 13 can also push the extension plate 10 to move, thereby causing the friction ring 9 to separate from the friction ring 8, so that the connecting shaft 406 can rotate normally.

[0039] Working principle: During soilless seedling cultivation, the cultivation cylinder 4011 is inserted upright into the central through hole of the placement seat 3. Culture medium is added to the cultivation cylinder 4011, and seedling cultivation begins. After seedling cultivation, the seedlings are removed. Then, motor 402 is turned on to rotate the lead screw 403, causing the lifting seat 405 to move downwards. After one set of seedlings is cultivated, motor 402 is turned on again to rotate the lead screw 403, causing the lifting seat 405 to move downwards, which in turn moves the connecting shaft 406 downwards. The worm gear 407 and worm 408... After engagement, the second motor 4010 drives the worm 408 to rotate, causing the worm wheel 407 to rotate, which in turn drives the connecting shaft 406 to rotate, turning the cultivation cylinder 4011 over to pour out the culture solution inside. After pouring, depending on the requirements of the next round of seedling cultivation, the cultivation cylinder 4011 can be turned over again or not. Then, the first motor 402 is turned on to drive the lead screw 403 to reverse, causing the lifting seat 405 to move upward, so that the cultivation cylinder 4011 can be reinserted into the through hole in the center of the placement seat 3.

A sliding rod 404 is fixedly mounted on the top of the mounting plate 401. The top end of the sliding rod 404 movably passes through the bottom of the lifting seat 405. A connecting shaft 406 is rotatably connected to the inner wall of the lifting seat 405 via a bearing. The outer wall of the connecting shaft 406 is fixed. A cultivation cylinder 4011 is installed, which is inverted and has a soil-holding trough 5 on its top.

A worm 408 is fixedly installed on the output end of the second motor 4010. The outer wall of the worm 408 is rotatably connected to the inner wall of the support plate 409 through a bearing.

[0043] There are 33 placement seats 3 and 33 culture cylinders 4011, which are evenly distributed on the placement frame 2. Every 9 culture cylinders 4011 form a group. The same group of culture cylinders 4011 is fixedly connected to the same connecting shaft 406. The left and right ends of the connecting shaft 406 are rotatably connected to the lifting seat 405 through bearings.

[0044] The placement base 3 includes a water-permeable base 301 and a water-permeable top cover 302. The water-permeable top cover 302 is fixedly installed on the top of the water-permeable base 301. A water-guiding groove 303 is provided on the top of the water-permeable base 301. The water-guiding groove 303 is connected to the central through hole of the placement base 3. The water-permeable hole on the water-permeable base 301 is smaller than the water-permeable hole on the water-permeable top cover 302.

[0045] Electric slide rails 14 are fixedly installed on both the front and back of the three-dimensional frame 1. A movable frame 15 is fixedly installed on the movable end of the electric slide rail 14. A water pipe 16 is fixedly installed on the inner top of the movable frame 15. A spray head 17 is connected to the bottom of the water pipe 16. The movable frame 15 is moved by the electric slide rail 14, which in turn moves the water pipe 16, so that the spray head 17 at the bottom of the water pipe 16 sprays water on the seedlings.

[0046] The left and right outer walls of the mobile frame 15 are fixedly installed with dripping pipes 18 by pipe clamps 19. The bottom of the dripping pipe 18 is connected to a dripper 20. The top of the water pipe 16 and the dripping pipe 18 are both connected to a flexible hose 21. The flexible hose 21 is connected to the pipe network inside the seedling greenhouse. The dripping pipe 18 is used to guide the culture solution or insecticide, etc., and then drips onto the seedlings through the dripper 20.

[0047] Working principle: During soilless seedling cultivation, the cultivation cylinder 4011 is inserted upright into the central through hole of the placement seat 3. Culture medium is added to the cultivation cylinder 4011, and seedlings are then cultivated. After cultivation, the seedlings are removed. Then, motor 402 is turned on, driving the lead screw 403 to rotate, causing the lifting seat 405 to move downwards. After one set of seedlings is cultivated, motor 402 is turned on again, driving the lead screw 403 to rotate, causing the lifting seat 405 to move downwards, which in turn drives the connecting shaft 406 to move downwards. After the worm gear 407 meshes with the worm 408, motor 4010 drives the worm 408 to rotate, causing the worm gear 407 to rotate, which in turn drives the connecting shaft 406 to rotate. The cultivation cylinder 4011 is flipped over to pour out the culture solution inside. After pouring, depending on the requirements of the next round of seedling cultivation, the cultivation cylinder 4011 is flipped again or not. Then, the motor 402 is turned on to drive the lead screw 403 to reverse, causing the lifting seat 405 to move upward, so that the cultivation cylinder 4011 is reinserted into the through hole in the center of the placement seat 3. During the seedling cultivation process, the moving frame 15 is moved by the electric slide rail 14, which in turn moves the water pipe 16 and the dripping pipe 18. The water in the water pipe 16 is sprayed onto the seedlings from the spray head 17, and the culture solution or insecticide in the dripping pipe 18 drips onto the seedlings from the dripper head 20.

[0050] The cultivation mechanism 4 includes a mounting plate 401, which is fixedly mounted on the three-dimensional frame 1. A motor 402 is fixedly mounted on the bottom of the mounting plate 401. A lead screw 403 is fixedly mounted on the output end of the motor 402. A lifting seat 405 is threaded onto the outer wall of the lead screw 403. A sliding rod 404 is fixedly mounted on the top of the mounting plate 401. The top end of the sliding rod 404 movably passes through the bottom of the lifting seat 405. A connecting shaft 406 is rotatably connected to the inner wall of the lifting seat 405 via a bearing. The outer wall of the connecting shaft 406 is fixed. A cultivation cylinder 4011 is installed, which is inverted and has a soil-holding trough 5 on its top. The cultivation cylinder 4011 is inserted into the through hole in the center of the placement seat 3. A worm gear 407 is fixedly installed on the outer wall of the connecting shaft 406. A support plate 409 is fixedly installed on the top of the mounting plate 401. A second motor 4010 is fixedly installed on the top of the mounting plate 401.

[0051] There are 33 placement seats 3 and 33 culture cylinders 4011, which are evenly distributed on the placement frame 2. Every 9 culture cylinders 4011 form a group. The same group of culture cylinders 4011 is fixedly connected to the same connecting shaft 406. The left and right ends of the connecting shaft 406 are rotatably connected to the lifting seat 405 through bearings.

The soil recycling bin 6 is designed to catch the poured soil. The inclination of the bottom of the soil recycling bin 6 allows the soil to slide along the bottom inner wall of the soil recycling bin 6 and then be washed into one side of the soil recycling bin 6 by dripping water, which facilitates the collection of soil. The filter screen 601 filters the water to prevent the soil from falling over due to excessive water in the soil recycling bin 6, which would cause sewage to splash everywhere.

[0054] Below the soil recycling bin 6 is a sewage recycling bin 7, which is placed on the ground. The bottom inner wall of the sewage recycling bin 7 is high in the middle and low on both sides. The sewage recycling bin 7 is set up to recycle sewage and prevent sewage from flowing around.

The partition plate 22 is set to support the soil recovery chamber 6 and prevent the soil recovery chamber 6 from pressing on the sewage recovery chamber 7, which would make it impossible to pull the sewage recovery chamber 7. The limit baffle 23 is set to remind the workers to place the sewage recovery chamber 7 in place.

[0056] Working principle: During soilless seedling cultivation, the cultivation cylinder 4011 is inserted upright into the central through hole of the placement seat 3. Culture medium is added to the cultivation cylinder 4011, and seedlings are then cultivated. After seedling cultivation, the seedlings are removed. Then, motor 402 is turned on to rotate the lead screw 403, causing the lifting seat 405 to move downwards. After one set of seedlings is cultivated, motor 402 is turned on again to rotate the lead screw 403, causing the lifting seat 405 to move downwards, which in turn moves the connecting shaft 406 downwards. After the worm gear 407 meshes with the worm 408, motor 4010 drives the worm 408 to rotate, causing the worm gear 407 to rotate, which in turn moves the connecting shaft 406. Rotate to flip the cultivation cylinder 4011 to pour out the culture solution inside. After pouring, depending on the requirements of the next round of seedling cultivation, choose to flip the cultivation cylinder 4011 again or not. Then, turn on the motor 402 to drive the lead screw 403 to reverse, so that the lifting seat 405 moves up, and the cultivation cylinder 4011 is reinserted into the through hole in the center of the placement seat 3. During the seedling cultivation process, the poured soil and dripping sewage fall into the soil recovery chamber 6.
