Description

Technical Field

[0001] The invention relates to the technical field of seed seedling production, in particular to a solanaceous vegetable seed seedling raising device and a seedling raising method thereof. Background Art

[0002] The Solanaceae vegetable seed seedling raising device is an agricultural equipment specially used for Solanaceae vegetable seed seedling raising. Seed germination requires a certain humidity environment. After Solanaceae vegetable seeds absorb water, the seed coat expands and softens, and oxygen can enter more easily, thereby activating the enzymes inside the seeds and promoting the growth and development of the embryo. Without enough water, the seeds cannot germinate normally. Therefore, watering can keep the seedling substrate (such as seedling soil or nutrient soil) moist and provide suitable germination conditions for the seeds.

[0003] Chinese invention patent publication number CN115299272B discloses a rice seedling raising device and method, comprising a base, the inner wall of which is connected to a vertical pipe via a bracket, a water pump installed inside the base, the water outlet of the water pump being connected to the bottom of the vertical pipe via an injection pipe, a plurality of rotating sleeves rotatably connected to the side walls of the vertical pipe, and a symmetrically arranged planting platform fixed to the bottom of the rotating sleeve. The above invention, by providing a series of structures, enables the device to water the rice during use.

[0004] However, the existing devices still have some problems during use;

[0005] 1. In the reference patent, the planting platforms are fixed in position, and watering must be achieved through multiple pipes or specific structures. This may result in uneven watering of rice on different planting platforms. Planting platforms close to the water source or water pump outlet may be overwatered, while those farther away may not be watered enough, affecting the consistency of rice growth. The provision of multiple pipes increases the complexity and manufacturing cost of the device, making the pipes prone to clogging or damage.

[0006] 2. During the rice seedling cultivation process, a dedicated person is required to manually start the water pump at regular intervals for watering operations, which undoubtedly increases manpower input and labor costs. Manual operation is subjective, and the operating habits and time arrangements of different operators may vary. It is difficult to ensure the accuracy and consistency of watering time, which in turn affects the growth quality of rice. Summary of the Invention

[0016] Furthermore, a method for raising seedlings of nightshade vegetable seeds, using the above-mentioned nightshade vegetable seed seedling raising device, comprises the following steps:

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0023] Secondly, the present invention cooperates with the magnet and the Hall sensor in the trigger mechanism. When the seedling tray rotates to a specific top position, it can accurately trigger the water pump to start, so that the atomizing nozzle can evenly spray the current seedling tray with a mist, ensuring that each seedling tray can obtain the appropriate amount of water and nutrient solution.

At the same time, the hinge points of connecting rod one and connecting rod two move synchronously and coordinatedly, so that the material receiving tray is smoothly converted from a parallel state to an inclined state, and the water or nutrient solution dripping from the seedling tray is automatically and thoroughly dumped out. This automated material receiving and dumping design does not require manual operation, which not only significantly improves work efficiency and reduces labor costs and labor intensity, but also effectively prevents the irrigated water or nutrient solution from dripping to other parts of the seedling rack, keeping the seedling environment clean and tidy.

[0043] The following combination Figures 1 to 10 As shown, an embodiment of the present invention provides a seedling raising device for Solanaceae vegetable seeds and a seedling raising method thereof. The seedling raising device for Solanaceae vegetable seeds includes a seedling raising frame 1, six seedling raising trays 2 are provided on the seedling raising frame 1, and a plurality of leakage holes 201 are opened at the bottom of the six seedling raising trays 2. The seedling raising frame 1 is connected to the seedling raising trays 2 by a transmission mechanism 3 and a vertical rotation mechanism 31. A top frame 5 is provided on the top of the seedling raising frame 1, and a watering mechanism 6 is provided on the top frame 5. The watering mechanism 6 includes a water tank 601, which is located on the top surface of the top frame 5. A water pump 602 is provided above the water tank 601, and the water inlet end of the water pump 602 is connected to the water outlet end of the water tank 601. A trigger mechanism 7 is provided on one side of the water pump 602, and the trigger mechanism 7 includes a magnet 701. The magnet 701 is located on the top surface of one side of the connecting frame 4, and a Hall sensor 702 is provided at the position corresponding to the magnet 701 on the bottom surface of the top frame 5. A material receiving mechanism 8 is provided at the bottom of the seedling raising tray 2.

[0044] Specifically, by the synergistic effect of transmission mechanism 3 and vertical rotation mechanism 31, the vertical rotation of six seedling trays 2 is realized, the vertical space of seedling rack 1 is fully utilized, the number of seedlings is increased in a limited space, and the cooperation of magnet 701 and Hall sensor 702 in trigger mechanism 7 realizes the intelligent control of irrigation, when seedling tray 2 rotates to the top specific position, it can accurately trigger water pump 602 to start, so that atomizing nozzle 604 sprays uniform mist to current seedling tray 2 and irrigates, and the cooperation of receiving mechanism 8 and linkage mechanism 9 realizes the automation of receiving and dumping. When seedling tray 2 rotates to the bottom, linkage mechanism 9 automatically unfolds receiving tray 801, so that it is converted from parallel state to inclined state, and the water or nutrient solution dripping from the seedling tray 2 that is undertaken is automatically dumped out. This automated design does not require manual operation, improves work efficiency, and reduces labor cost and labor intensity. At the same time, it is avoided that the water or nutrient solution of irrigation drips to other parts of seedling rack 1, keeping the clean and tidy and hygienic environment of seedling cultivation.

[0045] The transmission mechanism 3 includes a driving motor 301, which is arranged on the side wall of the seedling rack 1. The output end of the driving motor 301 is connected to a small gear 302. The transmission mechanism 3 also includes an auxiliary gear 303 and a large gear 304. The auxiliary gear 303 and the large gear 304 are both rotatably mounted on the side wall of the seedling rack 1. A toothed belt 305 is tensioned on the small gear 302, the auxiliary gear 303 and the large gear 304. The vertical rotation mechanism 31 is located between the seedling tray 2 and the transmission mechanism 3. The vertical rotation mechanism 31 includes four sprockets 3101 And two transmission chains 3103, a transmission chain 3103 is tensioned on every two sprocket wheels 3101, wherein a rotating shaft 3102 is connected between the two sprocket wheels 3101, and a sprocket wheel 3101 fixedly connected to the rotating shaft 3102 is connected to the large gear 304, and the tooth blocks at both ends of the rotating shaft 3102 are engaged with the tooth grooves inside the sprocket wheel 3101, and six mounting frames 3104 are provided on the two transmission chains 3103, and a connecting frame 4 is provided on each of the six connecting frames 4, and the connecting frame 4 is connected to the seedling tray 2.

[0046] Specifically, the driving motor 301 serves as the power source, and the small gear 302 drives the auxiliary gear 303 and the large gear 304 to rotate synchronously through the toothed belt 305. The large gear 304 transmits the power to the sprocket 3101 of the vertical rotation mechanism 31, and drives the mounting frame 3104 and the seedling tray 2 to rotate vertically through the transmission chain 3103. This power transmission and distribution method can ensure that the rotation movement of the seedling tray 2 is smooth and reliable, and provide stable mechanical support for the seedling cultivation of Solanaceae and eggplant vegetable seeds. Through the design of the vertical rotation mechanism 31, the six seedling trays 2 can be arranged in layers in the vertical space of the seedling rack 1. Compared with the traditional horizontal placement method, the space utilization rate is greatly improved, and the number of seedlings is increased in a limited space. It is suitable for large-scale seedling production of Solanaceae and eggplant vegetable seeds. The vertical rotation of the seedling tray 2 enables each seedling tray 2 to be evenly watered.

[0047] The watering mechanism 6 also includes a mounting plate 603, which is located on the bottom surface of the top frame 5. A plurality of atomizing nozzles 604 are evenly distributed in an array on the bottom surface of the mounting plate 603. The water inlet ends of the plurality of atomizing nozzles 604 are connected to the water outlet end of the water pump 602 through water pipes. The trigger mechanism 7 also includes a relay 703 and a switching power supply 704. The relay 703 and the switching power supply 704 are arranged outside the water tank 601, and the switching power supply 704 is deployed in parallel with the relay 703.

[0048] Specifically, when the seedling tray 2 starts to rotate vertically, when the seedling tray 2 rotates to a specific position at the top, the trigger mechanism 7 detects a signal and controls the water pump 602 to start. The water in the water tank 601 is pressurized by the water pump 602 and then transported to the atomizing nozzle 604 through the water pipe. The atomizing nozzle 604 atomizes the water and sprays it evenly on the nightshade vegetable seeds in the seedling tray 2. When the seedling tray 2 leaves this position, the trigger mechanism 7 controls the water pump 602 to stop working, completing the watering process and realizing the precise control of "watering as soon as it arrives and stopping as soon as it leaves", completely eliminating the need to manually switch the water pump 602, reducing labor costs and reducing human operation errors.

[0049] The material receiving mechanism 8 includes a material receiving tray 801, wherein the edge of the material receiving tray 801 for dumping the internal accumulated water adopts an arc chamfer design, and the material receiving tray 801 is located at the bottom end of the seedling tray 2, and connecting plates 802 are provided on both sides of one end of the seedling tray 2, and a rotating rod 803 is connected to the connecting plate 802. The rotating rod 803 is sleeved on one end of the material receiving tray 801, and the connecting plate 802 is hinged to one end of the material receiving tray 801, and a connecting rod 1 804 is rotatably installed on both sides of the other end of the seedling tray 2, and a connecting rod 2 805 is rotatably installed on the side wall of the other end of the material receiving tray 801, and the connecting end of the connecting rod 1 804 and the connecting rod 2 805 is hinged, and a support 806 is provided on the bottom surface of the material receiving tray 801, and a slide groove 807 is provided on the bottom surface of the support 806, and a linkage mechanism 9 is provided below the slide groove 807.

[0050] Specifically, the receiving tray 801 is located at the bottom end of the seedling tray 2. The accumulated water inside the seedling tray 2 can fall into the receiving tray 801 through the leakage hole 201 and be collected. The accumulated water in the seedling tray 2 due to watering or other reasons can be collected in time. The automatic collection can prevent the accumulated water from dripping everywhere, prevent the seedling environment from being polluted, and keep the seedling environment clean and hygienic.

[0051] The linkage mechanism 9 includes a stand 901, which is fixedly installed at the bottom of the seedling rack 1. A slide rod 902 is provided inside the stand 901 for sliding. A roller 903 is provided at the top of the slide rod 902. The roller 903 cooperates with the slide groove 807. A spring 904 is provided on the slide rod 902. The top of the spring 904 is connected to the roller 903. The bottom end of the spring 904 is connected to the stand 901. A connecting rod 905 is provided at the bottom end of the slide rod 902. The two ends of the connecting rod 905 are hinged to the slide rod 902.

[0052] Specifically, when one end of the bottom of the receiving tray 801 contacts the roller 903, the roller 903 rotates with the receiving tray 801 in the slide groove 807 and drives one of the slide bars 902 to slide downward inside the stand 901. The descending slide bar 902 drives the other slide bar 902 to slide upward inside the stand 901 under the action of the connecting rod 905, thereby lifting one side of the receiving tray 801, so that the receiving tray 801 is changed from a horizontal state to an inclined state, and the accumulated water inside the receiving tray 801 is poured out. By automatically pouring out the accumulated water, the accumulated water in the receiving tray 801 can be removed in time, realizing the automatic dumping function of the receiving tray 801, without the need for manual intervention, and improving the degree of automation of seedling production.

[0053] A method for raising seedlings of nightshade vegetables, using the above-mentioned nightshade vegetable seed seedling raising device, comprises the following steps:

[0054] Step 1: Lay a seedling substrate such as a mixture of peat, vermiculite, and perlite in six seedling trays 2 with a thickness of 5-8 cm, scrape the surface flat, and evenly sow Solanaceae vegetable seeds such as tomatoes and peppers on the surface of the substrate, cover with a thin layer of vermiculite or fine soil, and spray water to moisten it;

[0055] Step 2: Start the drive motor 301, and drive the vertical rotation mechanism 31 through the transmission of the small gear 302, the toothed belt 305 and the large gear 304. The vertical rotation mechanism 31 drives the six mounting frames 3104 and the seedling tray 2 to rotate vertically through the sprocket 3101 and the transmission chain 3103 to achieve layered seedling cultivation;

[0056] Step 3: When each seedling tray 2 rotates to the top, the magnet 701 on its connecting frame 4 enters the detection range of the Hall sensor 702 on the bottom surface of the top frame 5. When the magnet 701 approaches the Hall sensor 702, the Hall sensor 702 detects the change of the magnetic field and outputs an electrical signal to the relay 703. The relay 703 closes the contact, connecting the circuit of the switching power supply 704 and the water pump 602. The water pump 602 pumps water from the water tank 601, and the water flow is transported to the atomizing nozzle 604 on the bottom surface of the mounting plate 603 through the water pipe, and is evenly sprayed onto the substrate surface of the current seedling tray 2 in the form of mist;

[0057] Step 4: When the seedling tray 2 rotates to the bottom, the receiving tray 801 is automatically unfolded through the linkage mechanism 9, the slide rod 902 slides upward under the action of the spring 904, and the roller 903 moves along the slide groove 807, pushing the receiving tray 801 to rotate around the rotating rod 803, and the hinge points of the connecting rod 1 804 and the connecting rod 2 805 move synchronously, so that the receiving tray 801 is in a tilted state, and the water or nutrient solution dripping from the seedling tray 2 is poured out.

[0058] Working principle: First, press the start button of the drive motor 301, the drive motor 301 starts to run, and its output end drives the small gear 302 to rotate. The small gear 302 transmits power to the auxiliary gear 303 and the large gear 304 through the toothed belt 305, so that the auxiliary gear 303 and the large gear 304 rotate synchronously. The rotation of the large gear 304 provides power for the vertical rotation mechanism 31, and the sprocket 3101 connected to the large gear 304 starts to rotate, and drives the sprocket 3101 at the other end to rotate synchronously through the rotating shaft 3102. The two transmission chains 3103 start to move driven by the sprocket 3101, thereby driving the six mounting frames 3104 installed on the transmission chain 3103 to rotate vertically, and the connecting frame 4 is connected to the seedling tray 2. As the mounting frame 3104 rotates vertically, the six seedling trays 2 perform a layered rotation movement in the vertical space of the seedling rack 1. This rotational motion enables each seedling tray 2 to pass through different positions in turn, preparing for subsequent automatic watering and automatic pouring operations;

[0059] When the seedling tray 2 gradually rotates to a specific top position with the operation of the vertical rotating mechanism 31, the magnet 701 on the connecting frame 4 enters the detection range of the Hall sensor 702 on the bottom surface of the top frame 5. When the Hall sensor 702 detects that the magnet 701 is approaching, the magnetic field inside it changes. The Hall sensor 702 converts the magnetic field change into an electrical signal output, and the output electrical signal is transmitted to the relay 703. After receiving the signal, the relay 703 closes its contacts to connect the switching power supply 704 with the circuit of the water pump 602. After the circuit is connected, the water pump 602 starts to work and pumps water from the water tank 601. The water in the water tank 601 is transported to the multiple mist filters on the bottom surface of the mounting plate 603 through the water pipe under the pressurized action of the water pump 602. The atomizing nozzle 604, after the multiple atomizing nozzles 604 atomize the water, spray it in a uniform mist form on the substrate surface of the Solanaceae vegetable seeds in the seedling tray 2 located at the top specific position, to achieve the watering operation of the current seedling tray 2. As the vertical rotation mechanism 31 continues to operate, the seedling tray 2 gradually leaves the top specific position, and the magnet 701 also leaves the detection range of the Hall sensor 702. After the Hall sensor 702 detects no change in the magnetic field, the output signal disappears, the relay 703 disconnects the contact, and the water pump 602 stops working, completing the watering process of the current seedling tray 2. When the next seedling tray 2 rotates to the top specific position, the above-mentioned automatic watering operation is repeated, realizing the precise control of "watering as soon as it arrives and stopping as soon as it leaves";

[0060] When the seedling tray 2 gradually rotates to the bottom position with the operation of the vertical rotating mechanism 31, the material receiving tray 801 begins to enter the range of action of the linkage mechanism 9. When the material receiving tray 801 rotates to the bottom of the cultivation frame, the slide groove 807 on the bottom support 806 gradually contacts the roller 903 at the top of the slide rod 902 inside the stand 901. As the material receiving tray 801 continues to rotate, the roller 903 rolls in the slide groove 807 and drives one of the slide rods 902 to slide downward inside the stand 901. In the process of the slide rod 902 sliding downward, the spring 904 is compressed to store elastic potential energy. The descending slide rod 902 drives the other slide rod 902 to the stand 9 through the action of the connecting rod 905. 01 slides upward, and the upward sliding slide bar 902 pushes the receiving tray 801 to rotate around the rotating rod 803 through the cooperation of the roller 903 and the slide groove 807. At the same time, the hinge point of the connecting rod 1 804 and the connecting rod 2 805 moves synchronously, so that the receiving tray 801 is tilted. Under the action of gravity, the accumulated water inside the receiving tray 801 flows out along the inclined surface of the receiving tray 801, completing the automatic pouring operation. When the seedling tray 2 continues to rotate and the receiving tray 801 leaves the range of action of the linkage mechanism 9, the compressed spring 904 releases its elastic potential energy, pushing the slide bar 902 to slide upward and reset, and the roller 903 returns to its initial position, ready for collecting the dripping water in the seedling tray 2 next time.
