Technical Field

[0001] This invention relates to the field of tomato cultivation technology, and in particular to a tomato seedling cultivation device and cultivation method. Background Technology

[0002] In order to increase production and income and improve tomato yield, seedling cultivation is often used to cultivate tomatoes, which can not only make the seeds germinate earlier, but also ensure the germination rate.

[0003] Existing tomato seedling cultivation devices require manual addition of potting soil, and during subsequent cultivation, they cannot automatically and precisely add water and nutrient solution according to the location and growth status of each seedling; at the same time, when tomato seedlings are cultivated to the transplanting stage, manual pulling of seedlings can easily damage them. Summary of the Invention

[0004] The present invention addresses the problem of providing a tomato seedling cultivation device and its cultivation method, which solves the technical problems of existing tomato seedling cultivation devices requiring manual addition of cultivation soil, and the inability to automatically and accurately add water and nutrient solution according to the position and growth status of each seedling during subsequent cultivation; and the risk of damage to tomato seedlings when manually pulling them up during the transplanting stage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tomato seedling cultivation device includes side seats, a cultivation tray, and seedling holes. A cultivation tray is installed between two side seats, and several seedling holes are formed on the cultivation tray. An electric slide rail is installed on one of the side seats, and an electric sliding arm is slidably mounted on the electric slide rail. The electric sliding arm is connected to a hopper, and a discharge box is installed at the bottom of the hopper. A rotating roller is rotatably installed inside the discharge box, and several distributing plates are installed at equal angles on the rotating roller. A fixing plate is installed on the side wall of the discharge box, and a first pneumatic cylinder is installed on the fixing plate. A lifting baffle is installed at the telescopic end of the first pneumatic cylinder. Several installation pipes are installed on the fixing plate, and drip irrigation heads are installed at the bottom of the installation pipes, with the drip irrigation heads corresponding to the seedling holes.

[0007] Preferably, a rack and several isosceles trapezoidal seats are installed at equal intervals on another side seat, and a rotating tooth is installed at the end of the roller via a rotating shaft, the rotating tooth meshing with the rack.

[0008] Preferably, a limiting groove is provided on the top side of another side seat, and an installation groove is provided on the side wall of another side seat, and a bolt passes through the installation groove and is located in the limiting groove to be threadedly connected to the isosceles trapezoidal seat.

[0009] Preferably, a support plate is installed between the two side seats, a second pneumatic cylinder is installed on the bottom side of the support plate, and the telescopic end of the second pneumatic cylinder is connected to the lifting plate. The lifting plate is provided with a plurality of holes corresponding to the seedling holes.

[0010] Preferably, the fixing plate has an adjustment groove, and the mounting tube is limited in the adjustment groove by a nut.

[0011] Preferably, a water filling cylinder is installed on the fixing plate, and one-way valves are symmetrically installed on the top side of the water filling cylinder. One of the one-way valves is connected to the installation pipe through the water outlet pipe, and the other one-way valve is connected to the water inlet pipe.

[0012] Preferably, a polygonal rod is installed through the inside of the water filling cylinder, a piston is installed on the outside of the polygonal rod and inside the water filling cylinder, a wheel seat is installed at the bottom end of the polygonal rod, a roller is installed in the wheel seat, and a spring is fitted on the outside of the polygonal rod and between the wheel seat and the water filling cylinder.

[0013] A method for cultivating tomato seedlings, the specific steps of which are as follows:

[0014] Step 1: The electric sliding arm moves along the electric sliding rail, and the hopper is filled with potting soil or fertilizer. When the hopper moves, the rotating teeth rotate along the rack, which drives the rotating roller and the distribution plate to rotate through the rotating shaft, so that the potting soil or fertilizer in the hopper is evenly spread in the cultivation tray. At this time, the potting soil or fertilizer scattered on the cultivation tray is pushed into the seedling hole by moving the lifting baffle.

[0015] Step 2: Simultaneously, the roller moves along the top side of the side seat and the top side of the isosceles trapezoidal seat. When the roller passes through an isosceles trapezoidal seat, with the help of the spring, the roller drives the polygonal rod to move back and forth, thereby driving the piston to move back and forth in the water filling cylinder. When the piston moves up, the water or nutrient solution in the water filling cylinder enters the installation pipe through the one-way valve and the outlet pipe, and the drip irrigation is completed through the drip head. When the piston moves down, the water or nutrient solution enters the water filling cylinder through the inlet pipe and the one-way valve.

[0016] Step 3: At this point, the device moves to fill the seedling hole with potting soil, and then tomato seeds are placed in the potting soil in the seedling hole one by one. The device then moves to add fertilizer to the seedling hole, and drip irrigation of water or nutrient solution is carried out on the tomato seeds and subsequent tomato seedlings through the device.

[0017] The beneficial effects of the present invention are: when the hopper moves, the rotating teeth rotate along the rack, and the rotating shaft drives the rotating roller and the distribution plate to rotate, so that the culture soil or fertilizer in the hopper is evenly spread in the culture tray. At this time, the moving lifting baffle pushes the culture soil or fertilizer scattered on the culture tray into the seedling hole, thus completing the automatic addition of culture soil or fertilizer.

[0018] Simultaneously, the spacing and number of isosceles trapezoidal seats and installation pipes are adjusted according to the location of the seedling hole. When the isosceles trapezoidal seat is in the roller, the roller drives the polygonal rod to move back and forth under the cooperation of the spring, which in turn drives the piston to move back and forth in the water filling cylinder. When the piston moves up, the water or nutrient solution in the water filling cylinder enters the installation pipe through the one-way valve and the outlet pipe, and the drip irrigation head completes the drip irrigation of water or nutrient solution. When the piston moves down, the water or nutrient solution enters the water filling cylinder through the inlet pipe and the one-way valve, completing the automatic positioning and addition of water or nutrient solution.

[0019] After the seedlings have been cultivated, the second pneumatic cylinder drives the lifting plate and the seedling block to push the potting soil and tomato seedlings out of the seedling hole, making it easier to transplant the tomato seedlings later. Attached Figure Description

The cultivation tray 2 is installed between two side seats 1, and several seedling holes 3 are formed on the cultivation tray 2. An electric slide rail 4 is installed on one side seat 1, and an electric sliding arm 5 is slidably mounted on the electric slide rail 4. The electric sliding arm 5 is connected to a hopper 6. A discharge box 7 is connected to the bottom of the hopper 6. A rotating roller 8 is rotatably mounted inside the discharge box 7, and several distributing plates 9 are installed at equal angles on the rotating roller 8. A rack 19 and several isosceles trapezoidal seats 18 are installed at equal intervals on the other side seat 1. A rotating tooth 21 is installed at the end of the rotating roller 8 via a rotating shaft 20. The rotating tooth 21 meshes with the rack 19. 21 rotates along the rack 19, and drives the rotating roller 8 and the distribution plate 9 to rotate through the rotating shaft 20, so that the cultivation soil or fertilizer located in the hopper 6 is evenly spread into the cultivation tray 2. A fixing plate is installed on the side wall of the discharge box 7. A first air cylinder 10 is installed on the fixing plate. A lifting baffle 11 is installed on the telescopic end of the first air cylinder 10. Several installation pipes 12 are installed on the fixing plate. Drip irrigation heads 13 are installed at the bottom of the installation pipes 12 and correspond to the seedling holes 3. An adjustment groove is opened on the fixing plate. The installation pipes 12 are limited in the adjustment groove by nuts, which makes it easy to install different numbers of installation pipes 12 in the adjustment groove and to adjust the spacing of the installation pipes 12.

[0030] Another side seat 1 has a limiting groove on its top side and an installation groove on its side wall. The bolt passes through the installation groove and is threaded into the limiting groove to connect with the isosceles trapezoidal seat 18. This makes it easy to adjust the spacing of the isosceles trapezoidal seats 18 according to the spacing of the seedling holes 3, and also makes it easy to replace the isosceles trapezoidal seats 18. At different stages of seedling growth, the isosceles trapezoidal seats 18 of different heights can be replaced to adjust the amount of water and nutrient solution added.

[0031] A support plate 14 is installed between the two side seats 1. A second pneumatic cylinder 15 is installed on the bottom side of the support plate 14. The telescopic end of the second pneumatic cylinder 15 is connected to the lifting plate 16. Several holes 17 corresponding to the seedling holes 3 are provided on the lifting plate 16. The second pneumatic cylinder 15 drives the lifting plate 16 and the holes 17 to push the potting soil and tomato seedlings in the seedling holes 3 out of the seedling holes 3, which is convenient for the subsequent transplanting of tomato seedlings.

[0032] A water filling cylinder 22 is mounted on the fixed plate. One-way valves 23 are symmetrically mounted on the top side of the water filling cylinder 22. One one-way valve 23 is connected to the installation pipe 12 via the outlet pipe 29, and the other one-way valve 23 is connected to the inlet pipe 30. A polygonal rod 24 is installed through the inside of the water filling cylinder 22. A piston 25 is installed on the outside of the polygonal rod 24 and inside the water filling cylinder 22. A wheel seat 26 is mounted at the bottom end of the polygonal rod 24, and a roller 27 is installed inside the wheel seat 26. A spring 28 is fitted on the outside of the polygonal rod 24 and between the wheel seat 26 and the water filling cylinder 22. When… When roller 27 moves upward along isosceles trapezoidal seat 18, polygonal rod 24 moves upward, compressing spring 28. Piston 25 begins to move upward, and water or nutrient solution in water filling cylinder 22 enters installation pipe 12 through one-way valve 23 and outlet pipe 29. Water or nutrient solution is dripped through drip head 13. Roller 27 moves downward along isosceles trapezoidal seat 18 under the action of spring 28, and piston 25 moves downward. At this time, water or nutrient solution enters water filling cylinder 22 through inlet pipe 30 and one-way valve 23, completing the automatic positioning and addition of water or nutrient solution.

[0033] A method for cultivating tomato seedlings, the specific steps of which are as follows:

[0034] Step 1: The electric sliding arm 5 moves along the electric sliding rail 4, and the hopper 6 is filled with potting soil or fertilizer. When the hopper 6 moves, the rotating tooth 21 rotates along the rack 19, and drives the rotating roller 8 and the distribution plate 9 to rotate through the rotating shaft 20, so that the potting soil or fertilizer in the hopper 6 is evenly spread in the cultivation tray 2. At this time, the potting soil or fertilizer scattered on the cultivation tray 2 is pushed into the seedling hole 3 by moving the lifting baffle 11.

[0035] Step 2: Simultaneously, roller 27 moves along the top side of side seat 1 and the top side of isosceles trapezoidal seat 18. When roller 27 passes through an isosceles trapezoidal seat 18, with the cooperation of spring 28, roller 27 drives polygonal rod 24 to move back and forth, thereby driving piston 25 to move back and forth in water filling cylinder 22. When piston 25 moves up, water or nutrient solution in water filling cylinder 22 enters installation pipe 12 through one-way valve 23 and water outlet pipe 29, and completes drip irrigation of water or nutrient solution through drip irrigation head 13. When piston 25 moves down, water or nutrient solution enters water filling cylinder 22 through water inlet pipe 30 and one-way valve 23.

[0036] Step 3: At this point, the device moves to fill the seedling hole 3 with potting soil, and then the tomato seeds are placed in the potting soil in the seedling hole 3 in turn. The device then moves to add fertilizer to the seedling hole 3, and drip irrigation of water or nutrient solution is carried out on the tomato seeds and subsequent tomato seedlings through the device.

[0037] When the hopper 6 moves, the rotating teeth 21 rotate along the rack 19, and the rotating shaft 20 drives the rotating roller 8 and the distribution plate 9 to rotate, so that the potting soil or fertilizer in the hopper 6 is evenly spread into the cultivation tray 2. At this time, the moving lifting baffle 11 pushes the potting soil or fertilizer scattered on the cultivation tray 2 into the seedling hole 3, thus completing the automatic addition of potting soil or fertilizer.

[0038] Simultaneously, the spacing and number of isosceles trapezoidal seats 18 and installation pipes 12 are adjusted according to the position of the seedling hole 3. When the isosceles trapezoidal seat 18 is inside the roller 27, the roller 27 drives the polygonal rod 24 to move back and forth under the cooperation of the spring 28, which in turn drives the piston 25 to move back and forth in the water filling cylinder 22. When the piston 25 moves up, the water or nutrient solution in the water filling cylinder 22 enters the installation pipe 12 through the one-way valve 23 and the water outlet pipe 29, and the drip irrigation of water or nutrient solution is completed through the drip irrigation head 13. When the piston 25 moves down, the water or nutrient solution enters the water filling cylinder 22 through the water inlet pipe 30 and the one-way valve 23, and the automatic addition of water or nutrient solution is completed.

[0039] After the seedlings are cultivated, the second air cylinder 15 drives the lifting plate 16 and the hole block 17 to push the potting soil and tomato seedlings in the seedling hole 3 out of the seedling hole 3, which is convenient for the subsequent transplanting of tomato seedlings.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
