[0002] In the existing agricultural production, seedling cultivation is an important link to improve crop yield and quality. The selection of seedling cultivation substrate plays a vital role in crop growth. Traditional seedling cultivation substrates have problems such as waste, environmental pollution, and unstable substrate quality. At present, rice husks are used to prepare seedling cultivation substrates to reduce dependence on traditional resources, which is in line with the concept of environmental protection and sustainable development. Rice husks and other crop waste resources are used in combination with organic matter and mineral materials to prepare high-quality, environmentally friendly seedling cultivation substrates, providing good conditions for the healthy growth of crops. When using rice husks to prepare seedling cultivation substrates, it is necessary to stir a variety of raw materials such as rice husks, humus (leaf mold, decomposed compost, etc.), clay, sandpaper soil, mineral fertilizers, moisture regulators and water, and then pour them into a mold to make it.

[0003] In the existing rice seedling substrate production process, the materials for making the rice seedling substrate need to be homogenized.

[0037] When in use, the husk raw material enters the preparation tank 1 through the feed hopper 3, and various added raw materials are stored through the storage hopper 71. The feeding cylinder 72 at the bottom of the storage hopper 71 guides the raw material to the discharge pipe 73, and the driving motor 74 is started to drive the rotating shaft 75 and the spiral blade 76 to rotate in the feeding cylinder 72. The rotation of the spiral blade 76 makes the raw material enter the preparation tank 1 through the discharge pipe 73 at a uniform speed and continuously. The dispersion bucket 77 further disperses various raw materials in the preparation tank 1 as the stirring shaft 5 rotates. The servo motor 4 is started to drive the stirring shaft 5 to rotate in the preparation tank 1. The stirring blades 6 on the stirring shaft 5 mix the raw materials in the preparation tank 1 to ensure the uniformity of the raw materials and the stirring.

In this way, the grain raw materials and various additive raw materials can enter the preparation tank 1 at a uniform speed, and the raw materials can be preliminarily stirred and mixed during the uniform speed feeding process, which shortens the subsequent stirring time of the raw materials and improves the stirring effect of the raw materials.

[0038] Specifically, Figure 5 As shown, the uniform speed discharge control mechanism 8 includes a discharge port 81, a top plate 82, an electric cylinder 83, a bottom plate 84, a lifting cylinder 85, a mounting plate 86, a feeding motor 87, a feeding shaft 88, a spiral blade 89 and a discharge chute 810. The discharge port 81 is arranged at the bottom of the preparation tank 1, the top plate 82 is welded to the side wall of the discharge port 81, two electric cylinders 83 are bolted to the side wall of the top plate 82, the bottom plate 84 is fixedly connected to the output end of the electric cylinder 83, the lifting cylinder 85 is fixedly connected to the inner wall of the bottom plate 84, the lifting cylinder 85 is movably connected to the discharge port 81, the mounting plate 86 is bolted to the inner wall of the lifting cylinder 85, the feeding motor 87 is bolted to the side wall of the mounting plate 86, the feeding shaft 88 is fixedly connected to the output end of the feeding motor 87, the spiral blade 89 is fixedly connected to the side wall of the feeding shaft 88, and a plurality of discharge chutes 810 are opened at the top of the lift.

[0039] Specifically, Figure 5 As shown, the top of the lifting cylinder 85 is conical, and the lifting cylinder 85 with a conical top is used to prevent the accumulation of materials.

[0040] Specifically, Figure 5 As shown, a protrusion 11 is provided on the side wall of the discharge port 81 , and two anti-collision springs 12 are fixedly connected to the side wall of the chassis 84 , and the top of the anti-collision spring 12 is movably connected to the protrusion 11 .

[0041] After the stirring is completed, the electric cylinder 83 drives the chassis 84 and the lifting cylinder 85 to move up and down, controls the height of the lifting cylinder 85 at the discharge port 81, and can control the discharge chute 810 to be exposed inside the preparation tank 1. The feeding motor 87 drives the feeding shaft 88 and the spiral blade 89 to rotate, and the prepared seedling substrate is discharged at a uniform speed through the discharge chute 810. A protrusion 11 is provided on the side wall of the discharge port 81, and two anti-collision springs 12 are fixedly connected to the side wall of the chassis 84. When the chassis 84 is lifted to the vicinity of the discharge port 81, the anti-collision spring 12 contacts the protrusion 11 to play a buffering role, preventing the chassis 84 from directly colliding with the discharge port 81, thereby ensuring the stable operation of the equipment. Through the coordinated work of the electric cylinder 83 and the feeding motor 87, the uniform discharge of the seedling substrate is achieved, the blockage and waste in the discharge process are avoided, the production efficiency and the utilization rate of raw materials are improved, the uniform discharge of the raw materials after being stirred into a paddle is achieved, and the automation degree and work efficiency of the equipment are improved.

[0042] By adopting the above technical scheme, the problems of the existing rice seedling substrate mixing and homogenizing machine that cannot uniformly transport the preparation and addition raw materials into the preparation tank 1, the problem of low mixing effect and efficiency of multiple raw materials, and the problem of inconvenience in uniformly discharging the raw materials after being stirred into paddles are solved.

[0043] Working principle: When the present application is in use, first, the husk raw material enters the preparation tank 1 through the feed hopper 3, and various added raw materials are stored through the storage hopper 71. The feed cylinder 72 at the bottom of the storage hopper 71 guides the raw material to the discharge pipe 73, and the drive motor 74 is started to drive the rotating shaft 75 and the spiral blade 76 to rotate in the feed cylinder 72. The rotation of the spiral blade 76 allows the raw material to enter the preparation tank 1 through the discharge pipe 73 at a uniform speed and continuously. The dispersion bucket 77 further disperses the various raw materials in the preparation tank 1 as the stirring shaft 5 rotates. The servo motor 4 is started to drive the stirring shaft 5 rotates in the preparation tank 1, and the stirring blades 6 on the stirring shaft 5 mix the raw materials in the preparation tank 1. While adding materials, the liquid adding port 92 on the side wall of the ring tube 91 adds a proper amount of liquid into the preparation tank 1 through the liquid adding pipe 93. After the stirring is completed, the electric cylinder 83 drives the chassis 84 and the lifting cylinder 85 to move up and down, and controls the height of the lifting cylinder 85 at the discharge port 81, so that the discharge chute 810 can be controlled to be exposed inside the preparation tank 1. The feeding motor 87 drives the feeding shaft 88 and the spiral blade 89 to rotate, and the prepared seedling-raising substrate is discharged at a uniform speed through the discharge chute 810.
