Description

Technical Field

[0002] The continuous multi-stage drying line for seedling substrate preparation is an industrial equipment specially used for fast and uniform drying of seedling substrate. This drying line usually consists of multiple drying levels, which can realize the continuous drying process of the substrate, ensuring that the substrate reaches the ideal state required for seed germination and growth while maintaining appropriate humidity; Seedling medium is a medium specially used for plant seedlings. It provides necessary physical and chemical support for plant seeds to promote healthy growth. The preparation method of seedling medium usually includes mixing multiple ingredients, such as peat, coconut bran, vermiculite, perlite, fertilizer, seedling medium, biological agent and sterile water. When the seedling matrix is ​​dried, water vapor will float on the upper part of the seedling matrix. In order to avoid the water vapor from contacting the seedling matrix again, the water vapor needs to be removed in time. If the water vapor is extracted by a fan, the wind formed by the fan will blow on the seedling matrix. Since the seedling matrix is ​​light in weight and small in particles, it is easy to float in the air and cause air pollution. Therefore, in view of the above problems, a continuous multi-stage drying line based on the preparation of seedling matrix and a method of using the same are proposed. Summary of the invention

[0013] Method for using a continuous multi-stage drying line based on seedling substrate preparation, S1: When cleaning the water vapor generated during the drying of the seedling matrix, the seedling matrix is ​​transported to the upper part of the conveyor belt through the crushing assembly, and the first motor drives the first pulley to rotate slowly, and the first pulley drives the fixedly connected roller column to rotate, and the roller column drives the conveyor belt set on the outside to rotate. At this time, the two roller columns are rotatably connected to the inner side of the bracket frame to ensure the stability of the conveyor belt during rotation. The heating wire dries the seedling matrix on the conveyor belt. At this time, the water vapor generated enters between the conveyor belt and the rubber belt. At the same time, the water vapor moves upward. The water vapor is between the metal plates. According to the same principle, when the first pulley rotates, the second pulley is driven to rotate by the belt, and the belt drives the second pulley to rotate. The second pulley drives the connecting convex rod to rotate and the built-in roller column to rotate. The built-in roller column drives the rubber belt set on the outside to rotate, and drives the limiting inner groove when the built-in roller column rotates. The seat moves, and the limited inner groove seat drives the rotating bar, the metal plate and the water-absorbing sheet to rotate. When the metal plate and the water-absorbing sheet rotate, the water vapor between the metal plates or between the water-absorbing sheets can be slowly transported, so that the water vapor is transported to the outside of the bracket frame. When the water-absorbing sheet contacts the water-squeezing cylinder, the water-absorbing sheet and the metal plate rotate under the extrusion of the water-squeezing cylinder. At the same time, the water-squeezing cylinder is rotated and connected to the outside of the fixed roller. Under the extrusion of the water-squeezing cylinder, the water inside the water-absorbing sheet can be quickly squeezed out. The squeezed water falls to the upper part of the water guide plate and flows from the water guide plate to the outside of the bracket frame. When the water-absorbing sheet and the metal plate are separated from the water-squeezing cylinder, the rotating bar is driven to rotate under the elastic torsion of the clockwork spring. The rotating bar is rotatably connected to the inner side of the double-column slot hole opened in the limited inner groove seat. Under the limitation of the limited inner groove seat, the metal plate and the water-absorbing sheet remain vertical to the bracket frame. S2: When the seedling substrate is evenly dried, the second motor is started, and the second motor drives the fixed rod column to rotate. The fixed rod column is rotatably connected to the inner side of the support frame, which plays a role in limiting the rotation of the fixed rod column. The fixed rod column drives the toggle rod to rotate. When the toggle rod rotates, the seedling substrate on the upper part of the conveyor belt is turned over, so that the seedling substrate close to the conveyor belt can be turned out; S3: The seedling matrix is ​​crushed when being unloaded to prevent the seedling matrix from agglomerating. The seedling matrix is ​​prevented from falling from between the inclined plates to between the blades on the inner side of the upper part of the unloading frame and the upper part of the inclined plate. The second motor drives the shaft stick to rotate, and the shaft stick drives the fixed guide wheel to rotate. The fixed guide wheel drives the first gear to rotate. The fixed guide wheel is connected to the inner side of the unloading frame. The rotation of the first gear drives the second gear meshing on the outer side to rotate. The rotation direction of the second gear is opposite to that of the first gear, so that the seedling matrix can pass through between the two blades.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, by means of the conveyor belt, heating wire, support frame, metal plate and water-absorbing sheet, the device can slowly remove water vapor, and at the same time, the water vapor is quickly adsorbed to prevent it from contacting with the dried seedling medium, thereby ensuring the drying quality of the medium and the cleanliness of the environment, preventing the seedling medium from floating into the air due to the removal of water vapor, and ensuring that the air is not polluted; 2. In the present invention, the device realizes the overturning and drying of the seedling culture medium on the upper part of the conveyor belt by means of the fixed rod column and the toggle rod. This overturning action enables the medium originally close to the heat source to be turned out, so that the other side of the medium is also dried, thereby ensuring the uniformity of the drying of the entire medium, improving the drying efficiency and the quality of the final product; 3. In the present invention, the substrate is crushed by the provided feeding frame, inclined plate, shaft and blade. The reverse rotation of the second gear and the first gear allows the substrate to pass through and be cut between the two blades, effectively preventing the substrate from agglomerating, ensuring the uniformity of the substrate particles, providing convenience for the subsequent drying process, accelerating the drying speed and improving the drying effect.

[0021] Working process: when cleaning the water vapor generated during the drying of the seedling culture medium, the seedling culture medium is transported to the upper part of the conveyor belt 28 through the crushing component 3, the first motor 23 is started, the first motor 23 drives the first pulley 24 to rotate slowly, the first pulley 24 drives the fixedly connected rotating roller column 27 to rotate, the rotating roller column 27 drives the outer sleeve conveyor belt 28 to rotate, at this time, the two rotating roller columns 27 are rotatably connected to the inner side of the bracket frame 21 to ensure the stability of the conveyor belt 28 during rotation, and the heating wire 22 is started, the heating wire 22 dries the seedling culture medium on the conveyor belt 28, and the conveyor belt 28 is dried.
