TECHNICAL FIELD
[0001] The utility model relates to fertilizer production equipment technical field especially is involved in a humic acid fertilizer production is with vibrating screen device. BACKGROUND
[0002] As an organic fertilizer rich in various organic substances and nutrient elements required for plant growth, humic acid fertilizer plays a crucial role in agricultural planting. It can significantly improve the physical, chemical and biological properties of soil, enhance the water and fertilizer retention capacity of soil, and promote the activity of soil microorganisms, creating a good soil environment for crop growth. At the same time, humic acid fertilizer can also directly provide nutrients for crops, improve the stress resistance of crops, promote the growth and development of crops, increase the yield and quality of crops, and has important significance for ensuring the sustainable development of agriculture and food security.
[0003] In the production process of humic acid fertilizer, the screening link is one of the key steps to ensure product quality. The traditional humic acid fertilizer screening device usually adopts a simple vibrating screening method, but in actual production, this screening method seriously affects the production efficiency and product quality.
[0004] Humic acid fertilizer itself has certain viscosity. In the production process, due to the influence of factors such as humidity and temperature, the particles of humic acid fertilizer are prone to adhesion, forming blocky structures of different sizes. When these blocky humic acid fertilizers enter the traditional vibrating screening device, due to the large volume of the blocky materials, they are difficult to effectively disperse and move on the screen surface, resulting in a large number of particles meeting the particle size requirements being trapped in the screen oversize and unable to smoothly pass through the screen into the next production link. This makes the screening process take longer to complete, greatly reducing the screening efficiency and affecting the overall production capacity of the production line. Since the blocky humic acid fertilizer cannot be effectively dispersed and screened, these blocky materials are often directly discharged as waste in the traditional screening device. This not only causes a large amount of raw material waste, increasing production costs, but also brings additional burden to subsequent waste treatment due to the generation of a large amount of waste.

[0024] The bottom of the support frame 1 is provided with a castor wheel, which can facilitate the movement of the device. The screening box 2 and the storage box 11 are fixedly installed on the support frame 1. The screening box 2 is provided with two layers of screening assemblies. The screen hole of the upper layer of screening assemblies is larger than that of the lower layer of screening assemblies. The upper layer of screening assemblies is composed of a distribution plate 4, an adjusting baffle 6 and an agitator 5. The agitator 5 can scatter the humic acid fertilizer in blocks during rotation, so as to avoid waste of raw materials meeting the specifications and improve the discharge rate of raw materials. The lower layer of screening assemblies is composed of a vibrating screen 9. The vibrating screen 9 is slidably installed in the screening cylinder. The vibrating screen 9 is widely used in the screening device and belongs to the prior art. Therefore, the structure of the vibrating screen 9 will not be described in detail. In the present application, the vibrating screen 9 is used for secondary screening. Through the shaking characteristics of the vibrating screen 9, the screening efficiency is improved, and the screen hole is prevented from being blocked. The discharge end of the distribution plate 4 is a first discharge port 7. The discharge end of the vibrating screen 9 is a second discharge port 8. The first discharge port 7 and the second discharge port 8 are located on the front side of the screening cylinder. The materials discharged from the first discharge port 7 and the second discharge port 8 are waste materials screened out. The first discharge port 7 and the second discharge port 8 are in communication with the inner cavity of the waste box 10. The waste materials from the first discharge port 7 and the second discharge port 8 finally gather in the waste box 10. The humic acid fertilizer meeting the specifications is screened out and enters the storage box 11 from the inner cavity of the screening box 2.
[0025] As shown in Figure 2 and Figure 3 , the distribution plate 4 is obliquely installed in the interior of the storage box 11.

The adjusting baffle 6 and the larger opening on the upper end of the distribution box can hold more screening materials. The agitator 5 rotates counterclockwise on the distribution plate 4. The adjusting baffle 6 can move horizontally on the support rod 12. When the adjusting baffle 6 moves to the left, the distance between the adjusting baffle 6 and the distribution plate 4 becomes smaller. When the volume of the screening material is small, the screening material is prevented from sliding from the gap. When the volume of the screening material is large, the adjusting baffle 6 is moved to the right. In this way, the large-volume impurities can be prevented from accumulating above the distribution plate 4, which is helpful for the smoothness of the distribution plate 4. The adjusting baffle 6 is fixed on the support rod 12 through a fixing bolt 13. The support rod 12 has two support rods 12, which can stably support and guide the movement of the adjusting baffle 6.

[0027] The stirring shaft 501 is connected to the driving motor through a chain assembly, the driving motor is installed above the support frame 1, the first gear 504 is further installed on the stirring shaft 501, the first gear 504 meshes with the second gear 505, the second gear 505 is fixedly connected with the cleaning roller, the cleaning roller is located in the sieve box 2, and the cleaning roller is located above the vibrating screen 9. The bristles on the vibrating screen 9 clean the vibrating screen 9, ensure the smoothness of the screen holes on the vibrating screen 9, and improve the screening efficiency of the vibrating screen 9.
[0028] The lower bottom surface of the waste box 10 is provided with a sieve plate 14, the sieve plate 14 performs re-screening on the waste in the waste box 10, so that the waste of raw materials can be avoided, and the yield of qualified sieve material can be improved.
[0029] The storage box 11 is fixedly connected to the lower ends of the waste box 10 and the sieve box 2, and is used for collecting humic acid fertilizer particles meeting the specifications after screening. The bottom of the storage box 11 is provided with an inclined bottom plate, and the angle of the inclined bottom plate is generally 5°-15°, so that the materials can be easily gathered to the front side of the storage box 11.
