Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer production technology, specifically a mixing device for compound fertilizer preparation. Background Technology

[0002] The compound fertilizer rate is considered one of the important indicators for assessing the development level of a country's fertilizer industry and the degree of agricultural modernization. Compared with traditional single fertilizers, compound fertilizers not only have a higher content of nutrients, but also have a scientific and reasonable formula that can better meet the nutrient needs of plants at different growth stages, thereby promoting the healthy growth of crops. In addition, the use of compound fertilizers can significantly reduce farmers' manual input in the fertilization process, simplify the operation process, and thus effectively improve agricultural production efficiency.

[0003] In the process of using existing compound fertilizer preparation mixing devices, compound fertilizer raw materials are added to the mixing device, and then repeatedly stirred using several mixing shafts. Finally, the mixed compound fertilizer is discharged. However, when adding compound fertilizer raw materials, the raw materials may clump together due to factors such as air humidity during storage. Clumped raw materials are difficult to fully contact and mix with other components, resulting in uneven nutrient distribution and affecting the uniformity of the product and the fertilization effect.

[0004] Therefore, this utility model provides a mixing device for preparing compound fertilizer to solve the above problems. Utility Model Content

[0005] This invention provides a mixing device for preparing compound fertilizer, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mixing device for preparing compound fertilizer, comprising a base plate, and further comprising: a working frame fixedly installed on the top of the base plate, a mixing tank fixedly installed on the working frame, a feed pipe fixedly installed on the top of the mixing tank, and a crushing mechanism disposed inside the mixing tank for crushing agglomerated compound fertilizer raw materials.

[0007] The crushing mechanism includes a motor fixedly installed on the top of the mixing tank, a rotating shaft rotatably installed inside the mixing tank, a fixed filter ring fixedly installed on the inner wall of the mixing tank, a filter hopper fixedly installed on the fixed filter ring, a rotating disk fixedly installed on the side surface of the rotating shaft, a cleaning rod fixedly installed on the side surface of the rotating disk, a fixed frame fixedly installed on the end of the cleaning rod away from the rotating disk, and a crushing roller rotatably installed inside the fixed frame.

[0008] Preferably, the output end of the motor passes through the top of the mixing tank and is fixedly connected to the top end of the rotating shaft, and the rotating shaft passes through the filter hopper and is movably connected to the filter hopper.

[0009] Preferably, multiple cleaning rods are provided, and the multiple cleaning rods are arranged in a ring array on the side surface of the rotating disk. The multiple cleaning rods are in contact with the filter hopper, and the side surface of the crushing roller is in contact with the top of the fixed filter ring.

[0010] Preferably, a three-headed plate is fixedly connected to the side surface of the rotating shaft, and the three-headed plate is located directly below the filter hopper.

[0011] Preferably, a connecting rod is fixedly connected to the bottom of the three-head plate, and multiple connecting rods are provided. The connecting rods are arranged in a circular array on the three-head plate, and a V-shaped push plate is fixedly connected to the end of the connecting rod away from the three-head plate.

[0012] Preferably, a plurality of stirring blades are fixedly connected to the side surface of the rotating shaft, and the stirring blades are distributed in a linear array on the rotating shaft.

[0013] Preferably, a material draining plate is fixedly connected to the bottom of the rotating shaft, and a material discharge pipe is fixedly connected to the bottom of the mixing tank, with the material draining plate positioned directly above the material discharge pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model features a simple structure and convenient operation. Through the crushing mechanism, compound fertilizer raw materials enter the mixing tank via the feed pipe and fall onto the inclined surface of the filter hopper. Starting the motor causes the output end to drive the rotating shaft, which in turn drives the rotating disc. As the disc rotates, the cleaning rod scrapes along the inclined surface of the filter hopper to prevent raw material accumulation and blockage. Small particles fall directly into the mixing tank through the filter hopper, while clumps are intercepted and fall onto the top of the fixed filter ring. At this time, the fixed frame rotates with the cleaning rod, causing the crushing roller to roll on top of the fixed filter ring. The clumps are squeezed and ground into fine particles that meet the particle size requirements, which then fall through the filter holes to the bottom of the mixing tank, reducing uneven nutrient distribution and improving product uniformity and fertilization efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 5 As shown, this utility model provides a mixing device for preparing compound fertilizer. The mixing device for preparing compound fertilizer includes a base plate 1, and further includes: a working frame 2 fixedly installed on the top of the base plate 1, a mixing tank 3 fixedly installed on the working frame 2, a feed pipe 4 fixedly installed on the top of the mixing tank 3, and a crushing mechanism 5 disposed inside the mixing tank 3 for crushing the agglomerated compound fertilizer raw materials.

[0025] The crushing mechanism 5 includes a motor 501 fixedly installed on the top of the mixing tank 3, a rotating shaft 502 rotatably installed inside the mixing tank 3, a fixed filter ring 504 fixedly installed on the inner wall of the mixing tank 3, a filter hopper 503 fixedly installed on the fixed filter ring 504, a rotating disk 505 fixedly installed on the side surface of the rotating shaft 502, a cleaning rod 506 fixedly installed on the side surface of the rotating disk 505, a fixed frame 507 fixedly installed on the end of the cleaning rod 506 away from the rotating disk 505, and a crushing roller 508 rotatably installed inside the fixed frame 507.

[0026] The output end of the motor 501 passes through the top of the mixing tank 3 and is fixedly connected to the top of the rotating shaft 502. The rotating shaft 502 passes through the filter hopper 503 and is movably connected to the filter hopper 503.

[0027] Multiple cleaning rods 506 are provided, and the multiple cleaning rods 506 are arranged in a ring array on the side surface of the rotating disk 505. The multiple cleaning rods 506 are in contact with the filter hopper 503, and the side surface of the crushing roller 508 is in contact with the top of the fixed filter ring 504.

[0028] Using the above scheme: Compound fertilizer raw materials enter the mixing tank 3 through the feed pipe 4, first falling onto the inclined surface of the filter hopper 503. The motor 501 is started, and its output drives the rotating shaft 502 to rotate inside the mixing tank 3. The rotating shaft 502 simultaneously drives the rotating disk 505 to rotate. Because multiple cleaning rods 506 are arranged in a ring array on the side surface of the rotating disk 505 and are in close contact with the filter hopper 503, the cleaning rods 506 scrape along the inclined surface of the filter hopper 503 as the rotating disk 505 rotates, preventing the raw materials from accumulating and clogging on the inclined surface. Raw materials with smaller particles that can directly pass through the filter hopper 503 will fall directly to the bottom of the mixing tank 3 for subsequent mixing processes, while lumpy or larger particles will be filtered. The material is intercepted by the inclined bucket 503 and eventually falls onto the top of the fixed filter ring 504. At this time, the fixed frame 507 rotates synchronously with the cleaning rod 506, causing the crushing roller 508, which is rotatably installed inside the fixed frame 507, to roll on the top of the fixed filter ring 504. Since the side surface of the crushing roller 508 is in close contact with the top of the fixed filter ring 504, when the agglomerated material moves to the contact area between the two, the crushing roller 508 will apply a squeezing and grinding action to it, crushing the agglomerated material into fine particles that meet the particle size requirements. The crushed particles fall into the bottom of the mixing tank 3 through the filter holes on the fixed filter ring 504 and collect with other materials that have passed through the inclined bucket 503, thereby achieving preliminary screening and pretreatment of the raw materials and laying the foundation for subsequent efficient mixing.

[0029] like Figure 1 , Figure 2 and Figure 5 As shown, in order to facilitate the mixing of raw materials, a three-head plate 6 is fixedly connected to the side surface of the rotating shaft 502, and the three-head plate 6 is located directly below the filter hopper 503.

[0030] A connecting rod 7 is fixedly connected to the bottom of the three-head plate 6. Multiple connecting rods 7 are provided and are arranged in a circular array on the three-head plate 6. A V-shaped push plate 8 is fixedly connected to the end of the connecting rod 7 away from the three-head plate 6.

[0031] Multiple stirring blades 9 are fixedly connected to the side surface of the rotating shaft 502, and the stirring blades 9 are distributed in a linear array on the rotating shaft 502.

[0032] The above scheme is adopted as follows: the pre-treated raw materials are put into the mixing tank 3 according to the ratio, the rotating shaft 502 starts to rotate, and the rotating shaft 502 synchronously drives the three-head plate 6 and the stirring blade 9 to rotate. When the three-head plate 6 rotates with the rotating shaft 502, it drives the V-shaped push plate 8 to move in a circular motion along the inner wall of the mixing tank 3 through the connecting rod 7. The tip of the V-shaped push plate 8 faces the direction of rotation. The two side plates of the V-shaped structure can form a lateral thrust on the raw materials, so that the raw materials generate lateral flow during the pushing process, promoting the initial mixing of raw materials in different areas. The stirring blade 9 rotates under the drive of the rotating shaft 502. Its linear array distribution can fully stir the raw materials at different heights in the mixing tank 3, improve the mixing uniformity of compound fertilizer raw materials, and effectively avoid the problem of fertilizer nutrient imbalance caused by uneven mixing.

[0033] like Figure 1 , Figure 2 and Figure 5 As shown, in order to prevent material discharge blockage, a material discharge plate 10 is fixedly connected to the bottom of the rotating shaft 502, and a material discharge pipe 11 is fixedly connected to the bottom of the mixing tank 3. The material discharge plate 10 is located directly above the material discharge pipe 11.

[0034] The above scheme is adopted: the rotating shaft 502 drives the discharge plate 10 to rotate synchronously. When the discharge pipe 11 is discharging material, the rotating discharge plate 10 can continuously agitate and push the raw material directly above the discharge pipe 11. The rotation of the discharge plate 10 can effectively break the arch structure that the raw material may form under the action of gravity, and prevent the raw material from being blocked near the inlet of the discharge pipe 11 due to mutual compression or humidity. At the same time, the rotation of the discharge plate 10 can also accelerate the flow of the raw material to the bottom center area of ​​the mixing tank 3, ensuring that the raw material can be smoothly discharged through the discharge pipe 11, ensuring the continuous and stable operation of the entire mixing device, and reducing production interruptions and equipment maintenance needs caused by poor material discharge.

[0035] Working principle and usage process of this utility model:

[0036] When using the compound fertilizer preparation mixing device, the compound fertilizer raw materials are first fed into the mixing tank 3 through the feed pipe 4 according to the preset ratio. After the raw materials enter, they first contact the inclined surface of the filter hopper 503. The motor 501 is started, and its output end drives the rotating shaft 502 to rotate inside the mixing tank 3. The rotating shaft 502 drives the rotating disk 505 to rotate synchronously. At this time, the cleaning rods 506 distributed in a ring array make a scraping motion along the inclined surface of the filter hopper 503. Normal raw material particles are screened through the filter hopper 503 to the area where the three-head plate 6 is located, while the lumpy raw materials slide down the inclined surface to the top of the fixed filter ring 504. As the cleaning rods 506 continue to rotate, the fixed frame 507 drives the crushing roller 508 to roll on the surface of the fixed filter ring 504, crushing the lumpy raw materials, which fall into the bottom of the mixing tank 3 through the filter holes of the fixed filter ring 504.

[0037] While the raw materials are being pre-treated, the three-head plate 6 rotates with the rotating shaft 502, and drives the V-shaped push plate 8 to make a circular motion along the inner wall of the mixing tank 3 through the connecting rod 7. At the same time, the linearly arrayed stirring blades 9 are driven by the rotating shaft 502 to shear and stir the raw materials at different heights. During the mixing process, the discharge plate 10 continuously stirs the raw materials above the discharge pipe 11 at the same speed to destroy any possible accumulation arch bridge structure. When the raw materials have been mixed for a preset time, the electric valve of the discharge pipe 11 is opened to discharge the well-mixed compound fertilizer from inside the mixing tank 3.
