Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of organic fertilizer processing, in particular to a mixing device for granulating powdered commercial organic fertilizer. Background Art
[0002] Commercial organic fertilizer refers to a type of fertilizer that is made from various animal wastes (including animal manure, animal processing waste) and plant residues (cake fertilizer, crop straw, fallen leaves, dead branches, peat, etc.) using physical, chemical, biological or a combination of the three treatment technologies, and undergoes certain processing techniques (including but not limited to composting, high temperature, anaerobic, etc.) to eliminate harmful substances (pathogens, pest eggs, weed seeds, etc.) to achieve harmlessness standards, and complies with relevant national standards (NY 525-2012) and regulations. Compared with traditional organic fertilizers (commonly known as farmyard manure), commercial organic fertilizers are produced by standardized production enterprises, have good production processes and quality control, meet national organic certification standards, have better product maturity, are more thoroughly harmlessly treated, have more stable and reliable product quality, and can better provide a stable supply of nutrients. This type of product is becoming more and more popular among the public.
[0003] Most of the daily commercial organic fertilizer products are in powder form. During the fertilization process of farmers, when organic fertilizer is used as seed fertilizer, it is impossible to achieve "seed fertilizer and seed fertilizer co-sowing"; when organic fertilizer is used as base fertilizer or topdressing, a lot of manpower is required (or special equipment is required for spreading fertilizer, and powdered organic fertilizer is very easy to block the fertilizer outlet). At the same time, commercial organic fertilizers fermented only with organic materials have low nutrient content such as nitrogen, phosphorus and potassium. In order to solve these practical problems, it is necessary to add a certain amount of chemical fertilizers, biological agents, additives and other materials to the powdered organic fertilizer, fully mix them, and then granulate them, which can not only increase the nutrient content of organic fertilizers, but also facilitate farmers to apply commercial organic fertilizers at different times. In the common mixing device, various materials cannot be stirred evenly in the mixing device during the preparation process. After the mixing is completed, a large amount of residues are usually adhered to the inner wall of the device. Some of these residues are still highly adhesive. After a long time, they are adhered to the inner wall of the device, which will affect the next mixing work and the sanitary condition of the device. Utility Model Content
[0004] The utility model aims to provide a mixing device for granulating powdered commercial organic fertilizer, which can solve the above technical problems.
[0005] The utility model provides a mixing device for granulating and processing powdery commercial organic fertilizers, including a box body. An inlet is arranged at the top of the box body, and an outlet is arranged at the bottom. A cavity for mixing materials such as organic fertilizers, chemical fertilizers, biological bacterial agents and additives is arranged inside the box body. A motor is arranged outside the box body, and an output shaft of the motor is fixedly connected with a stirring rod. The stirring rod passes through the outer wall of the box body and is located inside the cavity. A plurality of stirring blades are evenly distributed on the outer surface of the stirring rod. A cleaning mechanism is further arranged inside the box body. The cleaning mechanism includes a scraping plate which is arranged in a fitting and sliding connection with the inner wall of the box body and a cylinder arranged outside the box body. The end of a piston rod of the cylinder is fixedly connected with the scraping plate. Specifically, the scraping plate is of an arc-shaped structure, and a plurality of cylinders are provided. The piston rods are symmetrically distributed on both sides of the scraping plate.
[0006] Further, a cleaning cotton layer is arranged on one side of the scraping plate close to the inner wall of the box body.
[0007] Further, a liquid inlet pipe inserted into the cavity is arranged on the box body. The end of the liquid inlet pipe located inside the cavity is sealed, and the other end is connected with a water supply mechanism. A plurality of atomizing water spray nozzles are arranged on the side wall of the liquid inlet pipe. The orientation of the atomizing water spray nozzles is horizontal. The position of the liquid inlet pipe is determined by not interfering with the rotation of the stirring blades.
[0008] The water supply mechanism includes a water pump and a water tank. The liquid in the water tank is conveyed into the liquid inlet pipe through the water pump and then sprayed into the box body through the atomizing water spray nozzles on the liquid inlet pipe. By arranging the atomizing water spray nozzles, water can be injected into the raw materials during the stirring and mixing process. Adding water can make the mixing process faster and also lay a foundation for later granulating the fertilizer, so that it is not necessary to inject water into the box body manually during the mixing process, realizing one-step water injection and mixing, improving the work efficiency and saving the working time of employees, and reducing the workload and working intensity of employees to a certain extent.
[0009] Further, the atomizing water spray nozzles are arranged at equal intervals along the extension direction of the liquid inlet pipe, making the spraying of water more uniform.
[0010] Further, a filter screen is arranged at the inlet, which can filter out some larger granular impurities in the fertilizer.
[0011] Further, support legs are arranged below the box body.
[0012] Further, a discharge pipe is connected to the outlet. The discharge pipe is of a bent structure, and an electromagnetic valve is arranged on the discharge pipe. The opening and closing of the discharge pipe are controlled by the electromagnetic valve. After the materials in the box body are mixed evenly, the electromagnetic valve is opened, and the materials are discharged along the discharge pipe.
[0013] Further, the discharge pipe is rotatably connected with the outlet.
[0014] Furthermore, an active circular groove is provided on the inner wall of the discharge port. One end of the discharge pipe close to the discharge port is fixedly connected with an annular plate, and the annular plate is located in the active circular groove and is rotatably connected thereto.
[0015] Furthermore, a handle is fixedly installed on the outer wall of the discharge pipe. By holding the handle, it is convenient to rotate the discharge pipe and adjust the orientation of the end of the discharge pipe.
[0016] Beneficial effects:
[0017] The material enters the interior of the box through the feed inlet and is evenly mixed with the participation of the stirring blades. After being discharged from the discharge port, the present utility model is provided with a cleaning structure. The scraping plate is driven by the piston rod to move along the interior of the box. The scraping plate is in contact with the inner wall of the box, and the outer side of the scraping plate wipes the inner wall of the box. As the scraping plate moves, the residues on the inner wall of the box are scraped off, causing the residues adhering to the inner wall of the box to fall off. The present utility model not only realizes the mixing of ordinary powdered commercial organic fertilizers with materials such as chemical fertilizers, biological bacterial agents, and additives, but also can conveniently and timely handle the residues on the inner wall of the box, avoiding affecting the next mixing operation and ensuring the hygiene condition of the entire device.

[0026] Embodiment 1
[0027] A mixing device for granulation processing of powdery commercial organic fertilizer, as Figure 1-2As shown in the figure, it includes a box body 1. Support legs 12 are provided below the box body 1. A feed inlet 2 is provided at the top of the box body 1. The feed inlet 2 is an open structure and is provided with a filter screen, which can filter out some larger particulate impurities in the material. A discharge outlet 3 is provided at the bottom of the box body 1. A cavity 4 for organic fertilizer mixing is provided inside the box body 1. A motor 5 is provided outside the box body 1. The output shaft of the motor 5 is fixedly connected with a stirring rod 6 through a coupling. The stirring rod 6 passes through the outer wall of the box body 1 and is located inside the cavity 4. The end of the stirring rod 6 is located on a bearing seat 14 provided on the side wall of the box body 1. A plurality of stirring blades 7 are evenly distributed on the outer surface of the stirring rod 6. In this embodiment, spiral stirring blades are adopted. A cleaning mechanism is also provided inside the box body 1. The cleaning mechanism includes a scraper 8 that is arranged in contact with and slidably connected to the inner wall of the box body 1 and a cylinder (not shown in the figure) provided outside the box body 1. The end of the piston rod 9 of the cylinder is fixedly connected to the scraper 8. Specifically, the scraper 8 is of an arc structure and is in contact with the inner wall of the box body. A cleaning cotton layer is provided on the side of the scraper 8 close to the inner wall of the box body, so as to facilitate wiping the inner wall of the box body 1. There are two cylinders, and the two piston rods 9 are symmetrically distributed on both sides of the scraper 8 respectively, so as to ensure that the scraper 8 will not shift during the movement process.
[0028] A liquid inlet pipe 10 inserted into the cavity 4 is provided on the box body 1. The end of the liquid inlet pipe 10 located inside the cavity 4 is sealed, and the other end is connected to a water supply mechanism. A plurality of atomizing water spray nozzles 11 are provided on the side wall of the liquid inlet pipe 10, which are arranged at equal intervals along the extension direction of the liquid inlet pipe 10, so that the spraying of water is more uniform. The orientation of the atomizing water spray nozzles 11 is the horizontal direction, and they spray water symmetrically towards both sides. The position of the liquid inlet pipe 10 is such that it does not interfere with the rotation of the stirring blades 7. The distance at which the atomizing water spray nozzles 11 spray water is such that the water can fall onto the surface of the material inside the box body 1. The above-mentioned water supply mechanism includes a water pump and a water tank. The liquid in the water tank is transported into the liquid inlet pipe 10 through the water pump, and then is sprayed into the box body through the atomizing water spray nozzles 11 on the liquid inlet pipe 10. By setting the atomizing water spray nozzles 11, water can be injected into the raw materials during the stirring and mixing process. Adding water can make the mixing process faster and also lay a foundation for later granulation of the fertilizer. It enables the mixing process to be completed without manually injecting water into the box body, achieving one-step water injection and mixing, improving work efficiency and saving the working time of employees, and reducing the workload and working intensity of employees to a certain extent. In addition, the liquid inlet pipe 10 has another function. When doing cleaning work, by changing the rotation speed of the water pump or using a booster pump, the water outlet speed of the atomizing water spray nozzles 11 is increased, so that the water can directly be sprayed onto the inner wall of the box body 1. In this way, the water slides down along the inner wall and can cover the entire inner wall. This can make the cleaning effect more thorough when the scraper 8 cleans the inner wall of the box body, and cleaning liquid can also be added to the water tank according to actual situations.
[0029] A discharge pipe 13 is connected to the discharge port 3. The discharge pipe 13 is of a bent structure. An electromagnetic valve is provided on the discharge pipe 13. The opening and closing of the discharge pipe 13 are controlled by the electromagnetic valve. After the materials in the box are evenly mixed, the electromagnetic valve is opened, and the materials are discharged along the discharge pipe 13.
[0030] Electrical components such as the above-mentioned motor and water pump can be purchased on the market. The electrical components such as the motor and water pump are equipped with power supplies, which are mature technologies in this field and have been fully disclosed. Therefore, they are not repeated in the specification.
[0031] Embodiment 2
[0032] The basic structure is the same as that of Embodiment 1, as Figure 1-3 shown. The difference is that the discharge pipe 13 is rotatably connected to the discharge port 3. Specifically, an active circular groove 15 is provided on the inner wall of the discharge port 3. One end of the discharge pipe 13 close to the discharge port 3 is fixedly connected with an annular plate 16. The annular plate 16 is located in the active circular groove 15 and is rotatably connected thereto. A handle 17 is fixedly installed on the outer wall of the discharge pipe 13. By holding the handle 17 by hand, it is convenient to rotate the discharge pipe 13, facilitating the adjustment of the orientation of the end of the discharge pipe.
[0033] Working and using process:
[0034] Mixing stage: The materials enter the cavity 4 in the box body 1 through the feed port 2. The motor 5 is started, and the stirring rod 6 drives the spiral stirring blades to rotate together. The spiral stirring blades start to rotate, pushing the materials from the feed port 2 towards the discharge port 3. During this process, the materials will continuously move and spread, enabling different particles to come into contact and disperse with each other. The rotation of the spiral stirring blades generates shear force, causing relative movement and mutual friction between the materials, thereby accelerating the mixing process. By adjusting parameters such as the rotation speed, rotation direction, and blade shape, the mixing uniformity and mixing time can be controlled.
[0035] Discharge stage: When discharging, place the aggregate bucket below the discharge pipe 13, open the electromagnetic valve on the discharge pipe 13, and the materials flow out along the discharge pipe 13 and fall into the aggregate bucket. Additionally, the discharge pipe 13 can be rotated by holding the handle 17, thereby changing the discharge direction of the discharge pipe 13, and the mixed organic fertilizer can be discharged into aggregate buckets in different directions and positions, improving the loading efficiency of the aggregate bucket.
[0036] Cleaning stage: After the materials in the cavity 4 are completely discharged, keep the scraper 8 at the position close to the feeding port 2. Start the water pump to drain the water in the water tank into the liquid inlet pipe 10 and spray it out from the atomizing water spray nozzles 11 to both sides, spraying onto the inner wall of the box body 1, which plays a role in wetting the residues on the inner wall. Then, turn off the water pump and start the cylinder. The piston rod 9 drives the scraper 8 to move towards the discharging port 3. The scraper 8 comes into contact with the inner wall of the box body 1, and the cleaning cotton layer outside the scraper 8 wipes the inner wall of the box body 1. As the scraper 8 moves, the residues on the inner wall of the box body 1 are scraped off, causing the residues adhering to the inner wall of the box body 1 to fall off. With the push of the scraper 8, they are discharged at the discharging port 3. The above cleaning operation can be repeated several times.
[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
