Description

Technical Field

[0001] This utility model relates to the field of seedling substrate technology, specifically to a distiller's grains substrate mixing device. Background Technology

[0002] Most existing seedling substrates use traditional soil or peat mixtures. These traditional substrates have low nutrient content and poor aeration, which can easily lead to root hypoxia in seedlings, thus failing to meet the needs of rapid seedling growth. At the same time, raw materials such as peat moss are expensive and non-renewable, which is not conducive to large-scale promotion.

[0003] Distillery lees are a material rich in organic matter. After fermentation, alcohol and harmful substances are removed, while organic nutrients are retained. This treated lees, combined with coconut coir, perlite, humic acid, and other materials in a specific ratio, forms a substrate. This seedling substrate based on distillery lees combines high nutrient content with excellent aeration, significantly improving seedling growth rate and survival rate.

[0004] However, there is currently no specially designed mixing device for this distiller's grains seedling substrate. If the traditional mixing method is used, all materials are poured in and mixed at once, and then discharged all at once. This not only results in poor mixing efficiency and an inability to evenly mix the various ingredients to meet the substrate requirements, but also in very low efficiency.

[0005] Therefore, a mixing device for distiller's grains matrix is ​​designed, which can not only improve the mixing uniformity, but also continuously mix and discharge, while ensuring the mixing uniformity and mixing efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a mixing device for distiller's grains substrate to solve the problems described in the background art.

[0007] The technical solution of this utility model is implemented as follows:

[0008] A mixing device for distiller's grains includes a horizontally rotating drum. Spiral blades for propelling materials forward and lifting plates for tumbling the materials are fixed to the inner wall of the drum. A drive mechanism for rotating the drum is also provided outside the drum. A cylindrical collecting cylinder is located above the front end of the drum. A cylindrical cylinder is rotatably mounted inside the collecting cylinder, and a stirring shaft is also provided inside the cylindrical cylinder. The central axes of the collecting cylinder, the cylindrical cylinder, and the stirring shaft coincide. At least three layers of connecting frames are arranged vertically and horizontally at intervals inside the cylindrical cylinder. The stirring shaft is fixedly connected to the center of the connecting frames. The outer edge of the connecting frames is fixedly connected to the inner wall of the cylindrical cylinder. A cutting mesh covering the entire cross-section of the inner surface of the cylindrical cylinder is also provided on the connecting frames. The top is open and a mounting frame is fixedly installed. Above the mounting frame are a stirring motor and at least two first quantitative feeding mechanisms. The top of the stirring shaft is driven by the stirring motor. The output end of the first quantitative feeding mechanism is located inside the cylinder. A conical hopper is connected to the bottom of the collecting cylinder. An inclined feed pipe is connected to the bottom of the conical hopper. The bottom of the feed pipe extends into the rotating cylinder. A second quantitative feeding mechanism is also provided outside the collecting cylinder. The output end of the second quantitative feeding mechanism is located inside the conical hopper. A water supply pipe extending along the central axis of the rotating cylinder is also provided inside the rotating cylinder. Support frames are connected to both ends of the water supply pipe. The support frames are located outside the rotating cylinder. Multiple annular sprayers are also provided on the water supply pipe. A flow pump that supplies water to the water supply pipe is also provided outside the rotating cylinder.

[0009] When using the above method, the distiller's grains and coconut coir are continuously fed into the cylinder through the first quantitative feeding mechanism. The distiller's grains and coconut coir fall into the cylinder from above. Then, the stirring motor drives the stirring shaft to rotate, which in turn drives the connecting frame and the cylinder to rotate. The connecting frame drives the cutting mesh to rotate, and the distiller's grains and coconut coir are continuously broken up by the rotating cutting mesh before falling. After being broken up by at least three layers of cutting mesh, the distiller's grains and coconut coir are prevented from clumping together, allowing them to be mixed evenly. Perlite is continuously fed into the cone hopper through the second quantitative feeding mechanism. This allows for the continuous addition of perlite and prevents it from being broken up and pulverized by the cutting mesh. The mixed distiller's grains, coconut coir, and perlite fall together from the feed pipe into the rotating drum. The drive mechanism drives the rotating drum to rotate, and under the action of the spiral blades, the three materials move together to the outlet of the rotating drum. Under the action of the lifting plate, the three materials are mixed again. The stirring of the lifting plate not only ensures that the three materials are mixed evenly but also avoids violent stirring. At the same time, the water supply pipe provides humic acid solution to the annular sprayer. The humic acid solution is sprayed in a ring around the inner wall of the rotating drum, which can spray the humic acid solution on the surface of the material and on the inner wall of the rotating drum. This ensures that the upper surface of the material in the rotating drum and the lower surface of the material in contact with the inner wall of the rotating drum can be evenly contacted with the humic acid solution, thereby improving the mixing uniformity.

[0010] A further technical solution is that the first quantitative feeding mechanism includes a first storage tank mounted on the top of the collecting cylinder, and a first auger feeder connected to the bottom of the first storage tank, with the outlet of the first auger feeder located inside the cylinder above.

[0011] When using the above scheme, the lees or coconut coir are continuously transported to the first storage tank via a conveyor belt. By driving the first auger feeder, the lees or coconut coir can be continuously and quantitatively output.

[0012] A further technical solution is that the second quantitative feeding mechanism includes a second storage tank mounted next to the collecting cylinder, and a second auger feeder connected to the bottom of the second storage tank. The outlet of the second auger feeder passes through the bucket wall of the cone bucket and enters the cone bucket.

[0013] When using the above scheme, perlite is continuously transported to the second storage bin via a conveyor belt, and the perlite is continuously and quantitatively output into the cone hopper by driving the second auger feeder.

[0014] A further technical solution is that an inverted cone cover is placed on top of the cylinder, and a first feed inlet is opened in the middle of the inverted cone cover. The outlet of the first auger feeder is located inside the first feed inlet and directly above it.

[0015] When using the above solution, the inverted cone cap can effectively prevent distiller's grains and coconut coir from splashing when cut by the cutting mesh.

[0016] A further technical solution is that the annular sprayer includes an annular tube and a duckbill nozzle. A water outlet tube is connected to the water supply tube, and the end of the water outlet tube is connected to the annular tube. The duckbill nozzle is located on the annular tube, and the number of duckbill nozzles is at least four. The duckbill nozzles are distributed at equal angles around the water supply tube, and the spray direction of the duckbill nozzles is vertical and away from the direction of the water supply tube.

[0017] When using the above scheme, the water from the water supply pipe enters the ring pipe through the outlet pipe, and then enters the duckbill nozzle for spraying through the ring pipe.

[0018] A further technical solution is that the connecting frame includes at least two connecting rods, which are distributed at equal angular intervals around the stirring shaft as the central axis. One end of the connecting rod is fixedly connected to the stirring shaft, and the other end of the connecting rod is fixedly connected to the inner wall of the cylinder.

[0019] A further technical solution is that a circular support platform is also provided around the inner wall of the collecting cylinder. Multiple hemispherical grooves arranged in the same circle are opened on the upper end face of the circular support platform. Balls are rotatably placed in the hemispherical grooves. An annular groove is opened at the bottom of the cylinder, and the annular groove is fitted on the ball. The cylinder is rotatably placed on the circular support platform through the annular groove.

[0020] A further technical solution is to connect an extension pipe to the outlet of the water supply pipe, with the end of the extension pipe extending beyond the range of the rotating drum, and the flow pump is connected to the extension pipe.

[0021] A further technical solution is that a circular wheel is fixedly sleeved on the outside of the rotating drum, and a roller support component is provided at the bottom of the rotating drum. The circular wheel and the roller support component are tactilely connected. The driving mechanism includes a driven wheel fixedly sleeved on the outside of the rotating drum, and also includes a drive motor and a gearbox fixed on the outside of the rotating drum. The output shaft of the drive motor is driven by the input end of the gearbox, and the output end of the gearbox is also provided with a driving wheel, which is driven by the driven wheel.

[0022] The beneficial effects of this utility model are as follows:

[0023] 1. Fine raw material processing: The lees and coconut coir are broken up by at least three layers of cutting mesh to prevent clumping and achieve uniform mixing. An inverted conical cover is set on the top of the cylinder to effectively prevent the lees and coconut coir from splashing when the cutting mesh is cutting.

[0024] 2. Reasonable addition of perlite: The second quantitative feeding mechanism continuously feeds the cone hopper, which can continuously add perlite and avoid it being broken up and pulverized by the cutting mesh.

[0025] 3. Excellent mixing effect: In the rotating drum, the lees, coconut coir and perlite are mixed again through the combined action of the spiral blades and the lifting plates. The stirring method of the lifting plates is gentle and can ensure uniform mixing.

[0026] 4. Uniform spraying of humic acid solution: The humic acid solution is sprayed in a ring around the inner wall of the rotating drum using a ring sprayer, so that the upper surface of the material and the lower surface of the material in contact with the inner wall of the rotating drum can be evenly contacted, thereby improving the mixing uniformity.

[0027] 5. Continuous feeding and discharging: Through the cooperation of multiple quantitative feeding mechanisms and the rotary drum, continuous feeding and discharging is achieved, which improves mixing efficiency. Attached Figure Description
