Description

Technical Field

[0001] This utility model relates to the field of vegetable seedling technology, specifically to a vegetable seedling substrate mixing and filling device. Background Technology

[0002] Vegetable seedling substrate is a lightweight, mixed material used to replace soil and provide sufficient nutrients and good growing conditions for vegetable seedlings. It is mainly composed of carbonized rice husks, mushroom residue, sugarcane bagasse, and fine sand, mixed in a specific ratio. Vegetable seedling substrate is an indispensable material in the vegetable seedling process. Currently, after the vegetable seedling substrate is mixed, it is directly filled into containers.

[0003] Utility model patent CN202320815271.7 discloses a substrate filling device suitable for tobacco seedling cultivation. This device includes a conveyor belt, a substrate box bolted to the top of the conveyor belt, a feed hopper connected to the top of the substrate box, a fixed shell bolted to the top of the substrate box, a first motor bolted to the inner wall of the fixed shell, a first gear fixedly sleeved at the output end of the first motor, a second gear and a third gear meshing on the surface of the first gear, a first rotating rod and a second rotating rod fixedly sleeved at the shafts of the second and third gears respectively, and the first and second rotating rods are rotatably sleeved together. The first rotating rod is rotatably sleeved with the inner wall of the substrate box, and the top of the second rotating rod is rotatably connected to the inner wall of the fixed shell. A stirring head is bolted to the surface of both the first and second rotating rods. A second motor is bolted to the surface of the substrate box, the output end of the second motor extending into the interior of the substrate box and bolted with a rotating block, which is rotatably connected to the inner wall of the substrate box. A discharge plate is bolted to the surface of the rotating block. The first motor rotates, driving the first gear to rotate. The first gear then drives the second and third gears to rotate. The rotation of the second and third gears causes the first and second rotating rods to rotate relative to each other. This relative rotation of the first and second rotating rods drives the stirring rod to rotate, thus mixing the substrate. This method achieves high mixing efficiency, saves mixing time, and improves work efficiency.

[0004] Although the substrate filling device for tobacco seedling cultivation facilitates substrate mixing, it suffers from several problems in practical use. The device directly discharges the substrate into containers located on a conveyor belt. However, this design reveals several key issues in real-world application. Firstly, the conveyor belt lacks a clamping structure for the containers. When the substrate pours into the containers, the impact force and the weight of the substrate itself easily cause the containers to tilt or even tip over. This not only affects filling efficiency but may also lead to substrate waste and device contamination. Secondly, after falling into the containers, the substrate often exhibits an uneven distribution with high porosity due to the lack of an effective distribution mechanism. This uneven substrate distribution is detrimental to uniform seed germination and growth. Therefore, we propose a substrate mixing and filling device for vegetable seedling cultivation. Utility Model Content

[0005] To solve the above problems, this utility model provides a vegetable seedling substrate mixing and filling device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] The vegetable seedling substrate mixing and filling device includes two symmetrical support plates. Each support plate has a connecting groove at the bottom of its outer wall. Two guide rods are fixed in the connecting grooves, and two springs are sleeved on the outside of the guide rods.

[0008] Two horizontal plates are fixed between the two support plates, and each horizontal plate has mounting holes.

[0009] A hollow mixing cylinder is fixed at the mounting hole at the top. A stirring shaft is rotatably mounted inside the mixing cylinder. Multiple stirring blades are coaxially connected to the stirring shaft. A first motor for driving the stirring shaft to rotate is installed at the top of the mixing cylinder. A connecting pipe is installed at the bottom of the mixing cylinder.

[0010] A hollow storage cylinder connected to a connecting pipe is fixed at the mounting hole below. A rotating shaft is rotatably mounted inside the storage cylinder. An auger is coaxially keyed to the outer wall of the rotating shaft. A discharge pipe is fixed at the bottom of the storage cylinder, and the auger is located inside the discharge pipe. A second motor for driving the rotating shaft is installed at the top of the storage cylinder.

[0011] A vibrating section is provided below the storage cylinder for fixing and vibrating the container to assist in filling.

[0012] Furthermore, the vibrating part includes a tray for supporting the container, with connecting blocks fixed at both ends of the tray, a guide rod passing through the connecting blocks and slidably connected to the connecting blocks, springs on both the upper and lower sides pressing against the connecting blocks, two vertical plates fixed at the top of the tray, each vertical plate being threadedly connected to a threaded rod, and clamping plates for holding the container being rotatably installed at the two opposite ends of the two threaded rods; a vibration motor is installed at the bottom of the tray.

[0013] Furthermore, each of the two opposite ends of the two threaded rods is coaxially fixed with an adjusting head, the adjusting head having a regular hexagonal cross-sectional shape.

[0014] Furthermore, each of the two opposing end faces of the two clamping plates is fixed with a support rod, which passes through the vertical plate and is slidably connected to the vertical plate.

[0015] Furthermore, the tray and the connecting block are integrally formed, and the size of the connecting block is adapted to the size of the connecting groove.

[0016] Furthermore, the clamp has an arc-shaped cross-section and is made of stainless steel.

[0017] Furthermore, a feeding port is installed at the top of the feeding cylinder, and a sealing cap is threadedly connected to the top of the feeding port.

[0018] Furthermore, a valve is installed at the connecting pipe, and the valve is fixedly connected to the connecting pipe via a flange.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. The mixing and storage system allows for the addition of various substrate production raw materials in a fixed ratio. As the mixing shaft and blades rotate, the raw materials are mixed. The mixed substrate is then directly discharged into the storage tank for storage. This design facilitates the mixing of seedling substrates and offers the advantage of easy operation.

[0021] 2. The vibrating mechanism serves two purposes: First, rotating the threaded rods on both sides clamps the container, ensuring its stability during substrate filling. Second, after filling, a vibrating motor drives the tray and container to vibrate. The high-frequency vibration causes the substrate particles to settle naturally under the combined force of gravity and vibration, filling the bottom and corners of the container and preventing localized gaps or looseness. This uniform compaction ensures consistent seed implantation depth, reduces seedling height differences, and improves the overall uniformity of the vegetables. Attached Figure Description

Each support plate 1 has a connecting groove 10 at its bottom outer wall. Two guide rods 11 are fixed inside the connecting groove 10, and two springs 12 are sleeved on the outside of the guide rods 11. Two horizontal plates 2 are fixed between the two support plates 1, each with a mounting hole 20. A hollow mixing cylinder 3 is fixed at the mounting hole 20 at the top. A stirring shaft 32 is rotatably mounted inside the mixing cylinder 3. Multiple stirring blades 33 are coaxially connected to the stirring shaft 32. A device for... A first motor 31 drives the stirring shaft 32 to rotate; a connecting pipe 34 is installed at the bottom of the mixing cylinder 3; a hollow storage cylinder 4 is fixed at the mounting hole 20 below and is connected to the connecting pipe 34; a rotating shaft 41 is rotatably installed inside the storage cylinder 4; an auger 42 is coaxially keyed to the outer wall of the rotating shaft 41; a discharge pipe 43 is fixed at the bottom of the storage cylinder 4, and the auger 42 is located inside the discharge pipe 43; a second motor 40 for driving the rotating shaft 41 to rotate is installed at the top of the storage cylinder 4; a vibrating part 5 for fixing and vibrating the container to assist filling is provided below the storage cylinder 4. The vibrating unit 5 includes a pallet 50 for supporting the container. Both ends of the pallet 50 are fixed with connecting blocks 51. A guide rod 11 passes through the connecting blocks 51 and is slidably connected to the connecting blocks 51. Springs 12 on both the upper and lower sides are pressed against the connecting blocks 51. Two vertical plates 53 are fixed to the top of the pallet 50. Threaded rods 54 are threadedly connected to the vertical plates 53. Clamping plates 57 for holding the container are rotatably installed at the two opposite ends of the two threaded rods 54. A vibration motor 52 is installed at the bottom of the pallet 50.

[0037] In this embodiment, each of the two opposite ends of the two threaded rods 54 is coaxially fixed with an adjusting head 55, the adjusting head 55 having a regular hexagonal cross-sectional shape. The adjusting head 55 facilitates the rotation of the threaded rods 54, improving the convenience and smoothness of operation.

[0038] In this embodiment, support rods 56 are fixed to the two opposite ends of the two clamping plates 57. The support rods 56 pass through the vertical plate 53 and are slidably connected to it. The support rods 56 guide the horizontal movement of the clamping plates 57, ensuring the stability of the clamping plates 57.

[0039] In this embodiment, the pallet 50 and the connecting block 51 are integrally formed, and the size of the connecting block 51 is adapted to the size of the connecting groove 10. The integrally formed design improves the strength and durability of the pallet 50 and the connecting block 51, while the adapted size facilitates the smooth movement of the connecting block 51 within the connecting groove 10.

[0040] In this embodiment, the clamping plate 57 has an arc-shaped cross-section and is made of stainless steel. The arc-shaped design of the clamping plate 57 better adapts to the container, increasing the stability and flexibility of the clamping. The stainless steel material of the clamping plate 57 provides good corrosion resistance and strength, extending its service life.

[0041] In this embodiment, a feeding port 30 is installed on the top of the feeding cylinder 3, and a sealing cap is threaded onto the top of the feeding port 30. This design has the advantages of easy feeding and good sealing performance.

Then, the user turns on the power to the first motor 31, and the first motor 31 starts to work. The output shaft of the first motor 31 rotates, driving the stirring shaft 32 and the stirring blades 33 to rotate. The rotating stirring blades 33 then stir and mix the various raw materials. Next, the user opens the valve 35, and the proportioned matrix falls into the storage cylinder 4 through the connecting pipe 34.

[0044] During filling, the user first places the container between the two clamping plates 57. Then, the user rotates the adjusting heads 55 on both sides, which drives the threaded rod 54 to rotate. The threaded rod 54 then drives the clamping plates 57 on both sides to move closer to the container. When the clamping plates 57 clamp the container, the container is fixed. Then, the user turns on the power to the second motor 40. The second motor 40 starts to work. The output shaft of the second motor 40 rotates, which drives the rotating shaft 41 and the auger 42 to rotate. As the auger 42 rotates, the substrate falls into the container through the discharge pipe 43. Then, the user turns on the power to the vibrating motor 52. The vibrating motor 52 starts to work and drives the pallet 50 to vibrate. Under the high-frequency vibration of the pallet 50 driven by the vibrating motor 52, the substrate is filled to the bottom and corner areas of the container.
