Description

Technical Field

[0001] The present invention relates to the technical field of soilless cultivation, and particularly relates to an automatic sowing device for soilless cultivation. Background Art

[0002] Soilless cultivation (also known as hydroponics or nutrient solution cultivation) is a cultivation technique that does not use natural soil but provides necessary nutrients for plants by supplying nutrient solutions. This technique has extensive applications and important significance in agricultural production. The core principle of soilless cultivation is to provide water and nutrients required for plant growth through artificially prepared nutrient solutions. The nutrient solutions contain various mineral elements required for plant growth, such as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, etc. These elements are dissolved in water in ionic form and are directly absorbed by the root system to meet the growth needs of plants. Among them, the hydroponic method directly immerses the root system of plants in the nutrient solution without using any solid substrate, and this method is commonly used in the cultivation of some small plants and leafy vegetables.

[0003] Patent No. CN202311725626.4 discloses an automatic sowing device for soilless cultivation, including: a conveying device for conveying a seedling tray; an automatic sowing mechanism arranged outside the conveying device, and the automatic sowing mechanism is used for mechanized sowing of the seedling tray on the conveying device; and a cultivation box arranged at the end of the conveying device, and the cultivation box is used for irrigation and cultivation treatment of the sown seedling tray. Further, as a preference, the automatic sowing mechanism includes: a base frame symmetrically arranged on both sides of the conveying direction of the conveying device; a sliding frame vertically slidably arranged on the side of the base frame close to each other; a driving cylinder fixed on the base frame, and the output end of the driving cylinder is connected to the sliding frame; and a plurality of sowing components linearly arranged and all arranged between the two sliding frames, and the plurality of sowing components are fixed into a whole with the two sliding frames on both sides through connecting columns.

[0004] The above patent solves the problem that in the existing soilless cultivation technology during the sowing process, the number of seeds planted in each substrate and the planting depth of the seeds will affect the germination rate of the seeds, resulting in low planting efficiency; however, it cannot sow multiple plants simultaneously in a single sowing tube and can meet the nutrient supplementation of each plant. Summary of the Invention

[0005] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose an automatic sowing device for soilless cultivation.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions: An automatic seeding device for soilless cultivation, comprising a seeding unit and a feeding unit. The feeding unit is installed on one side and the bottom of the seeding unit. The feeding unit includes a cultivation mechanism and an auxiliary mechanism installed on one side of the upper end face edge of the cultivation mechanism. Feeding mechanisms are arranged on both sides of the bottom of the cultivation mechanism, and stabilizing mechanisms are arranged on both sides of the lower end face edge of the cultivation mechanism.

[0007] Preferably, the cultivation mechanism includes a cultivation tray and a cultivation ring groove arranged in the inner cavity of the cultivation tray. An insertion groove is formed on one side of the inner end face of the cultivation ring groove. A ring filter screen is arranged at the bottom of the cultivation ring groove. Feeding holes are arranged at the bottom of the cultivation tray and around the periphery of its bottom. Since the bottom of the inner cavity wall of the cultivation tray is a concave structure, workers can pour water from top to bottom into the inner cavity of the auxiliary vertical cylinder. After the water bears in the insertion groove, it penetrates downward through the bottom of the ring filter screen. The water continuously accumulates in the inner cavity of the cultivation tray. When the liquid level height of the liquid exceeds the opened feeding holes, the liquid will pass through the inner cavity of the feeding holes and pour downward from the middle position along the bottom of the outer end face of the cultivation tray into a single seeding tube. The seeds will simultaneously penetrate through the inner cavity of the opened feeding holes and vertically drop into the single seeding tube. At this time, the seeds are arranged in four groups in the single seeding tube, and the liquid spreads from the middle to the periphery, so that the liquid can better supplement nutrients to the plants in the single seeding tube from the middle to the periphery.

[0008] Preferably, the auxiliary mechanism includes an auxiliary vertical cylinder and a stabilizing clamp arranged at the top position of the outer end face of the auxiliary vertical cylinder. The other side of the stabilizing clamp is connected with a nutrient solution cylinder. Both sides of the nutrient solution cylinder are attached to the outer end face of the auxiliary vertical cylinder through support frames. A feeding pipe is installed at the bottom of the nutrient solution cylinder. The other end of the feeding pipe penetrates through the outer end face of the cultivation tray. Pour the auxiliary nutrient solution from top to bottom into the inner cavity of the nutrient solution cylinder. When sliding downward along the inner cavity of the cultivation tray, a very small amount of nutrient solution will directly drop into the single seeding tube, and the rest of the most auxiliary nutrient solution can be mixed with the water in the inner cavity of the cultivation tray. After the liquid level of the mixed liquid is higher than the feeding holes, it will pour downward into the single seeding tube, so that the plants can be moistened by the nutrient solution while being soaked in the nutrient mixture, strengthening the absorption effect, improving the planting success rate, ensuring that the seeds and seedlings can obtain sufficient and uniform nutrient solution supply in the initial stage, contributing to the rapid germination of the seeds and the healthy growth of the seedlings. The plants can obtain more comprehensive nutrient support in the initial growth stage, improving the planting success rate. When the mixed nutrient solution is poured into the seeding tube, it can evenly soak the seeds and seedlings. This uniform soaking method helps the root development and overall growth of the plants, improving the growth speed and quality of the plants.

[0009] Preferably, the bottom of the auxiliary vertical cylinder is inserted and fitted into the inner cavity of the insertion groove, so that the outer end wall of the auxiliary vertical cylinder is attached to the inner cavity wall of the insertion groove. The other end of the feeding pipe penetrates into the outer end face of the cultivation tray.

[0010] Preferably, the material feeding mechanism includes a first material feeding pipe and an assembly disk arranged on the inner end surface of a plurality of groups of first material feeding pipes. A second material feeding pipe is vertically arranged at the middle position of the assembly disk. Seeds falling downward due to gravity can be temporarily stored in the inner cavity of the culture disk. When the staff needs to plant multiple plants in a single sowing pipe, the second material feeding pipe is blocked, so that the seeds can enter the inner cavity of the single sowing pipe downward through the four groups of first material feeding pipes opened, thus achieving the effect of sowing multiple plants. When only single-plant planting is required in a single sowing pipe, the blocked second material feeding pipe is released, so that water flow, nutrient solution and seeds directly fall downward through the second material feeding pipe into the single sowing pipe. By releasing the blocked second material feeding pipe, the water flow, nutrient solution and seeds directly fall into the sowing pipe, ensuring the accurate placement of the seeds. This precise sowing method avoids waste of seeds, improves the success rate of sowing, ensures that each seed can obtain sufficient water and nutrients, and is beneficial to the germination of seeds and the healthy growth of seedlings.

[0011] Preferably, the upper end surfaces of the first material feeding pipe and the second material feeding pipe vertically penetrate into the inner cavity of the material feeding hole, making the material feeding mechanism and the culture mechanism an integral whole.

[0012] Preferably, a stabilizing mechanism is clamped between two groups of the first material feeding pipes. The stabilizing mechanism includes a stabilizing outer ring and a base arranged at the bottom position of the inner cavity wall of the stabilizing outer ring. Inner clamping pieces are vertically arranged on both sides of the upper end surface of the base.

[0013] Preferably, the sowing unit includes a mounting rack and an insertion cross-rack horizontally mounted in the inner cavity of the mounting rack. A material placing pipe is vertically mounted in the inner cavity of the mounting rack. A track is horizontally inserted through the middle position of the insertion cross-rack. The device to be sown is adapted to the soilless cultivation pipe as a whole. Both ends of the track are fixedly connected to the fixed support points, so that the insertion cross-rack can slide parallel on the upper end surface of the track with the opened lower cavity as a fulcrum, enabling the whole device to move to the required accurate position.

[0014] By fitting the outer end surface of the soilless cultivation pipe at the intermediate interval between the arranged material feeding mechanism and the stabilizing mechanism, when the whole device moves, the outer end surface of the soilless cultivation pipe can be clamped by the inner end surfaces of the two inner clamping pieces, maintaining the stability of the device during the moving state.

[0015] The staff puts the seeds to be sown into the inner cavity of the device from the top of the material placing pipe. And because the material placing pipe vertically penetrates through the inner cavity of the series connection ring, the series connection ring is stably clamped by the arranged positioning frame and the horizontal insertion rod, maintaining its stability during sowing.

[0016] Preferably, the mounting bracket includes an assembly bracket and positioning brackets arranged on both sides of the outer end face of the assembly bracket. The relatively arranged positioning brackets are connected by a horizontally inserted rod. A series connection ring is arranged between the two groups of horizontally inserted rods. A positioning cross block is horizontally arranged between the assembly bracket and the positioning bracket.

[0017] Preferably, the inserted cross frame includes a frame body and a lower cavity opened at the middle position of the bottom of the frame body. Insertion holes are vertically opened on both sides of the bottom of the frame body. The frame body is horizontally inserted into the inner cavity of the assembly bracket.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The whole device to be sown is adapted to the soilless cultivation pipe. The two ends of the track are fixedly connected to the fixed support points, so that the inserted cross frame can slide parallel to the upper end face of the track with the opened lower cavity as the fulcrum, enabling the whole device to move to the required accurate position. The staff puts the seeds to be sown into the inner cavity of the device from the top of the feeding pipe. Since the feeding pipe vertically penetrates through the inner cavity of the series connection ring, the series connection ring is stably clamped by the arranged positioning brackets and the horizontally inserted rod to maintain its stability during sowing.

[0019] The staff can pour water from top to bottom into the inner cavity of the auxiliary vertical cylinder. After the water bears in the insertion groove, it penetrates downward through the bottom of the ring filter screen. The water continuously accumulates in the inner cavity of the culture dish. When the liquid level height of the liquid exceeds the opened material passing hole, the liquid will pass through the inner cavity of the material passing hole and pour downward along the bottom position of the outer end face of the culture dish from the middle position into the single sowing pipe. The seeds will simultaneously penetrate through the inner cavity of the opened material passing hole and vertically fall into the single sowing pipe. At this time, the seeds are arranged in four groups in the single sowing pipe, and the liquid spreads from the middle to the surrounding, so that the liquid can better supplement nutrients to the plants in the single sowing pipe from the middle to the surrounding.

[0020] Pour the auxiliary nutrient solution from top to bottom into the inner cavity of the nutrient solution cylinder. When sliding downward along the inner cavity of the culture dish, very few nutrient solutions will directly fall into the single sowing pipe. Most of the remaining auxiliary nutrient solutions can be mixed with the water in the inner cavity of the culture dish. After the liquid level of the mixed liquid is higher than the material passing hole, it will pour downward into the single sowing pipe, enabling the plants to be moistened by the nutrient solution first while being soaked by the nutrient mixed liquid, strengthening the absorption effect and improving the planting success rate.

[0021] When only single-plant planting is required in the single sowing pipe, release the blocked second material passing pipe, so that the water, nutrient solution and seeds directly fall downward into the single sowing pipe from the second material passing pipe, ensuring that each seed can obtain sufficient water and nutrients, which is beneficial to the germination of the seeds and the healthy growth of the seedlings.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Refer to Figures 1-8, Example 1, an automatic sowing device for soilless cultivation, comprising a sowing unit 1 and a feeding unit 2. The feeding unit 2 is installed on one side and the bottom of the sowing unit 1. The feeding unit 2 includes a cultivation mechanism 21 and an auxiliary mechanism 22 installed on one side of the upper end face edge of the cultivation mechanism 21. Feeding mechanisms 23 are arranged on both sides of the bottom of the cultivation mechanism 21, and stabilizing mechanisms 24 are arranged at both sides of the lower end face edge of the cultivation mechanism 21.

[0026] The cultivation mechanism 21 includes a cultivation tray 211 and a cultivation ring groove 212 arranged in the inner cavity of the cultivation tray 211. An insertion groove 213 is opened on one side of the inner end face of the cultivation ring groove 212. A ring filter screen 214 is arranged at the bottom of the cultivation ring groove 212. Feeding holes 215 are arranged at the bottom of the cultivation tray 211 and surround the periphery of its bottom. Since the bottom of the inner cavity wall of the cultivation tray 211 is a concave structure, the staff can pour water from top to bottom into the inner cavity of the auxiliary vertical cylinder 221. After the water bears in the insertion groove 213, it penetrates downward through the bottom of the ring filter screen 214. The water continuously accumulates in the inner cavity of the cultivation tray 211. When the liquid level height of the liquid exceeds the opened feeding holes 215, the liquid will pass through the inner cavity of the feeding holes 215 and pour downward from the middle position along the bottom of the outer end face of the cultivation tray 211 into a single sowing pipe. The seeds will simultaneously penetrate through the inner cavity of the opened feeding holes 215 and vertically fall into the single sowing pipe. At this time, the seeds are arranged in four groups in the single sowing pipe, and the liquid spreads from the middle to the periphery, so that the liquid can better supplement the nutrition of the plants in the single sowing pipe from the middle to the periphery.

[0027] Embodiment 2. The auxiliary mechanism 22 includes an auxiliary vertical cylinder 221 and a stable clamp 222 arranged at the top position of the outer end face of the auxiliary vertical cylinder 221. The other side of the stable clamp 222 is connected to a nutrient solution cylinder 224. Both sides of the nutrient solution cylinder 224 are attached to the outer end face of the auxiliary vertical cylinder 221 through a support frame 223. A feeding pipe 225 is installed at the bottom position of the nutrient solution cylinder 224. The other end of the feeding pipe 225 penetrates through the outer end face of the culture dish 211. Pour the auxiliary nutrient solution into the inner cavity of the nutrient solution cylinder 224 from top to bottom. When sliding down along the inner cavity of the culture dish 211, a very small amount of the nutrient solution will directly fall into a single seeding pipe, and most of the remaining auxiliary nutrient solution can be mixed with the water flow in the inner cavity of the culture dish 211. After the liquid level of the mixed liquid is higher than the material passing hole 215, it will pour down into the single seeding pipe, so that the plants can be moistened by the nutrient solution while being soaked in the nutrient mixed liquid, enhancing the absorption effect, improving the planting success rate, ensuring that the seeds and seedlings can obtain sufficient and uniform nutrient solution supply in the initial stage, contributing to the rapid germination of the seeds and the healthy growth of the seedlings, enabling the plants to obtain more comprehensive nutritional support in the initial growth stage, improving the planting success rate. When the mixed nutrient solution is poured into the seeding pipe, it can evenly soak the seeds and seedlings. This uniform soaking method helps the root development and overall growth of the plants, improving the growth speed and quality of the plants.

[0028] Embodiment 3. The bottom of the auxiliary vertical cylinder 221 is inserted and fitted into the inner cavity of the insertion groove 213, so that the outer end wall of the auxiliary vertical cylinder 221 is attached to the inner cavity wall of the insertion groove 213. The other end of the feeding pipe 225 penetrates into the outer end face of the culture dish 211. The material passing mechanism 23 includes a first material passing pipe 231 and an assembly disk 232 arranged on the inner end face of a plurality of first material passing pipes 231. A second material passing pipe 233 is vertically arranged at the middle position of the assembly disk 232. The upper end faces of the first material passing pipe 231 and the second material passing pipe 233 both vertically penetrate into the inner cavity of the material passing hole 215, making the material passing mechanism 23 and the culture mechanism 21 an integral whole. The seeds that fall downward due to gravity can be temporarily stored in the inner cavity of the culture dish 211. When the staff needs to plant multiple plants in a single seeding pipe, block the second material passing pipe 233, so that the seeds can enter the inner cavity of the single seeding pipe downward through the four opened first material passing pipes 231, thus achieving the effect of multi-plant seeding. When only single-plant planting is required in a single seeding pipe, release the blocked second material passing pipe 233, so that the water flow, nutrient solution and seeds directly fall downward into the single seeding pipe through the second material passing pipe 233. By releasing the blocked second material passing pipe 233, the water flow, nutrient solution and seeds directly fall into the seeding pipe, ensuring the accurate placement of the seeds. This precise seeding method avoids the waste of seeds, improves the seeding success rate, ensures that each seed can obtain sufficient water and nutrients, and is beneficial to the germination of the seeds and the healthy growth of the seedlings.

[0029] Embodiment 4. A stabilizing mechanism 24 is clamped between two groups of first material feeding pipes 231. The stabilizing mechanism 24 includes a stabilizing outer ring 241 and a base 242 disposed at the bottom of the inner cavity wall of the stabilizing outer ring 241. Inner clamping pieces 243 are vertically disposed on both sides of the upper end surface of the base 242.

[0030] The seeding unit 1 includes a mounting frame 11 and an intersecting transverse frame 12 horizontally mounted in the inner cavity of the mounting frame 11. A material placing pipe 13 is vertically mounted in the inner cavity of the mounting frame 11. A track 14 is horizontally inserted through the middle position of the intersecting transverse frame 12. The whole device to be seeded is adapted to the soilless cultivation pipe, and both ends of the track 14 are fixedly connected to fixed support points, so that the intersecting transverse frame 12 can slide parallel to the upper end surface of the track 14 with the opened lower cavity 122 as a fulcrum, enabling the whole device to move to the required accurate position.

[0031] By fitting the outer end surface of the soilless cultivation pipe at the middle interval between the provided material feeding mechanism 23 and the stabilizing mechanism 24, when the whole device moves, the outer end surface of the soilless cultivation pipe can be clamped by the inner end surfaces of the two groups of inner clamping pieces 243, maintaining the stability of the device in the moving state.

[0032] Embodiment 5. The staff puts the seeds to be seeded into the inner cavity of the device from the top of the material placing pipe 13. Since the material placing pipe 13 vertically penetrates through the inner cavity of the series connection ring 114, the series connection ring 114 is stably clamped by the provided positioning frame 112 and the horizontally inserted rod 113 to maintain its stability during seeding.

[0033] The mounting frame 11 includes an assembly frame 111 and positioning frames 112 disposed on both sides of the outer end surface of the assembly frame 111. The relatively arranged positioning frames 112 are connected by horizontally inserted rods 113. A series connection ring 114 is disposed between the two groups of horizontally inserted rods 113. A positioning cross block 115 is horizontally disposed between the assembly frame 111 and the positioning frame 112.

[0034] The intersecting transverse frame 12 includes a frame body 121 and a lower cavity 122 opened at the middle position of the bottom of the frame body 121. Intersecting holes 123 are vertically opened on both sides of the bottom of the frame body 121. The frame body 121 is horizontally inserted through the inner cavity of the assembly frame 111.

[0035] In summary: An automated sowing device for soilless cultivation includes a sowing unit 1 and a feeding unit 2. The feeding unit 2 is installed on one side and the bottom of the sowing unit 1. The feeding unit 2 includes a cultivation mechanism 21 and an auxiliary mechanism 22 installed on one side of the upper end face edge of the cultivation mechanism 21. Feeding mechanisms 23 are provided on both sides of the bottom of the cultivation mechanism 21, and stabilizing mechanisms 24 are provided at both sides of the lower end face edge of the cultivation mechanism 21. The whole device for sowing is adapted to the soilless cultivation pipe. The two ends of the track 14 are fixedly connected to the fixed support points, so that the inserted cross-frame 12 can slide parallel on the upper end face of the track 14 with the opened lower cavity 122 as the fulcrum, enabling the whole device to move to the required accurate position; By fitting the outer end face of the soilless cultivation pipe at the intermediate interval between the provided feeding mechanism 23 and the stabilizing mechanism 24, when the whole device moves, it can clamp the outer end face of the soilless cultivation pipe through the inner end faces of the two inner clamping pieces 243, maintaining the stability of the device during the movement state; The staff puts the seeds to be sown into the inner cavity of the device from the top of the material placement pipe 13. Since the material placement pipe 13 vertically penetrates through the inner cavity of the series connection ring 114, the series connection ring 114 is stably clamped by the provided positioning frame 112 and the horizontal insertion rod 113, maintaining its stability during sowing; The seeds falling downward due to gravity can be temporarily stored in the inner cavity of the cultivation tray 211. When the staff needs to plant multiple plants in a single sowing pipe, the second feeding pipe 233 is blocked, so that the seeds can enter the inner cavity of the single sowing pipe downward through the four first feeding pipes 231 provided, thus achieving the effect of sowing multiple plants; Since the bottom of the inner cavity wall of the cultivation tray 211 is an inward concave structure, the staff can pour water into the inner cavity of the auxiliary vertical cylinder 221 from top to bottom. After the water is received in the insertion groove 213, it penetrates downward through the bottom of the ring filter 214. The water continuously accumulates in the inner cavity of the cultivation tray 211. When the liquid level height exceeds the provided feeding holes 215, the liquid will pass through the inner cavity of the feeding holes 215 and pour downward from the middle position along the bottom of the outer end face of the cultivation tray 211 into the single sowing pipe. The seeds will simultaneously penetrate through the inner cavity of the provided feeding holes 215 and fall vertically downward into the single sowing pipe. At this time, the seeds are arranged in four rows in the single sowing pipe, and the liquid spreads from the middle to the surrounding, so that the liquid can better supplement the nutrition of the plants in the single sowing pipe from the middle to the surrounding; Pour the auxiliary nutrient solution into the inner cavity of the nutrient solution cylinder 224 from top to bottom. When sliding down along the inner cavity of the cultivation tray 211, a very small amount of the nutrient solution will directly fall into the single seeding tube, and most of the remaining auxiliary nutrient solution can be mixed with the water flow in the inner cavity of the cultivation tray 211. After the liquid level of the mixed liquid is higher than the material passing hole 215, it will pour down into the single seeding tube, so that while the plants are soaked in the nutrient mixed liquid, they can be first moistened by the nutrient solution, strengthening the absorption effect, improving the planting success rate, ensuring that the seeds and seedlings can obtain sufficient and uniform nutrient solution supply in the initial stage, contributing to the rapid germination of the seeds and the healthy growth of the seedlings, enabling the plants to obtain more comprehensive nutrient support in the initial growth stage, improving the planting success rate. When the mixed nutrient solution is poured into the seeding tube, it can evenly soak the seeds and seedlings, and this uniform soaking method helps the root development and overall growth of the plants, improving the growth speed and quality of the plants; When only single-plant planting is required in the single seeding tube, release the blocked second material passing tube 233, so that the water flow, nutrient solution and seeds directly fall downward from the second material passing tube 233 into the single seeding tube. By releasing the blocked second material passing tube 233, the water flow, nutrient solution and seeds directly fall into the seeding tube, ensuring the accurate placement of the seeds. This precise seeding method avoids the waste of seeds, improves the seeding success rate, ensures that each seed can obtain sufficient water and nutrients, and is beneficial to the germination of the seeds and the healthy growth of the seedlings.
