Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of chemical fertilizer production and transportation, especially to a chemical fertilizer production and transportation machine with screening function. BACKGROUND

[0002] With the promotion of industrial revolution, the production scale of chemical fertilizer is gradually expanded, and the requirement for production efficiency is higher and higher, which promotes the emergence of chemical fertilizer production and transportation machine to realize more efficient and stable material transportation and adapt to the industrialization process of chemical fertilizer production. In modern chemical fertilizer production, intelligent technology is gradually integrated, computer technology and communication technology are used to realize centralized management of the transportation machine group, and the work tasks of each transportation machine can be reasonably arranged according to the production plan and material demand.

[0003] In the early development of chemical fertilizer industry, the production scale is small, and the material transportation mainly relies on manual handling. For example, workers use shovels to move raw materials from one place to another, or use hand carts to transport chemical fertilizer semi-finished products. This way is low in efficiency, high in labor intensity, and very limited in transportation capacity, which is difficult to meet the needs of large-scale chemical fertilizer production.

[0004] The existing U-shaped conveying equipment cannot screen the chemical fertilizer raw materials during transportation. If the small particles of raw materials are not screened in the subsequent processing such as mixing and granulation, it may lead to uneven distribution of nutrients. In the production of compound fertilizer, large particle nitrogen fertilizer raw materials and small particle phosphorus fertilizer raw materials may not be fully and uniformly mixed due to their different physical properties during mixing. After screening, the raw materials with similar sizes are mixed, which can make the distribution of nitrogen, phosphorus and potassium nutrients in the fertilizer particles more uniform, ensuring that there will be no local overabundance or shortage of nutrients when crops absorb nutrients. In addition to particles, there are also dust residues in chemical fertilizer raw materials. These dusts will adhere to the surfaces of the spiral conveying piece and the arc-shaped filtering structure after contacting them. SUMMARY

[0005] In view of the above problems that all the chemical fertilizer raw materials cannot be screened during transportation, and different particle sizes of raw materials may lead to uneven distribution of nutrients if not screened in the subsequent processing such as mixing and granulation, the utility model is proposed.

[0027] Before pouring the chemical fertilizer raw material, a pair of vibration devices arranged at the vertical surface of the U-shaped conveying box 1 are started, then the spiral conveying piece connected with the output end of the driving motor 4 is started, and then the chemical fertilizer raw material is poured, with the pouring of the chemical fertilizer raw material, the spiral conveying piece will convey the chemical fertilizer raw material to the discharge port, in the conveying process, because of the vibration generated by the vibration device 24 and the cooperation of the arc-shaped filtering structure, the unqualified particles in the chemical fertilizer particles will fall into the Y-shaped collecting frame 5 through the arc-shaped filtering plate 8, and finally fall into the rectangular storage box, at this time, the dust in the chemical fertilizer raw material will float in the air between the Y-shaped collecting frame 5 and the rectangular storage box due to the vibration force, at this time, the dust particles floating in the air can be sucked into the rectangular box connected with the air suction equipment by starting the air suction equipment arranged at the vertical surface of the rectangular storage box 1.

[0028] Embodiment 2

[0029] With reference to Figures 3-7 For the second embodiment of the utility model, which is different from the first embodiment, a pair of rectangles are arranged in the rectangular groove 10, and a cylindrical guide rod 11 is arranged at the vertical surface of each rectangle, and an arc-shaped extension sleeve 12 is arranged through the rod body of the cylindrical guide rod 11.

[0030] An arc-shaped extension block is further arranged in the arc-shaped extension sleeve 12, a rectangular extension plate 13 is slidably arranged on the upper surface of the arc-shaped extension block, a rectangular baffle 14 is rotatably connected to the vertical surface of the two sides of the rectangular extension plate 13, a circular hole is further arranged at the vertical surface of the rectangular extension plate 13, a tension spring 15 is further arranged in the pair of circular holes, a cylindrical limiting rod 16 is further arranged at the vertical surface of the arc-shaped extension sleeve 12, and a circular rod 17 is further connected between the pair of cylindrical limiting rods 16.

[0031] A T-shaped mounting groove is further arranged at the intersection of the U-shaped conveying box 1 and the arc-shaped filtering structure 6, a pair of auxiliary circular rods 18 are arranged in the T-shaped mounting groove, a pair of rectangular mounting plates 19 that can move relative to each other are further arranged on the rod body of the auxiliary circular rods 18, a mounting strip 20 is arranged at the vertical surface of the opposite sides of the pair of rectangular mounting plates 19, a bidirectional threaded rod 21 is further arranged through the vertical surface of the rectangular mounting plate 19, a torsion rod 22 is further arranged at the circular surface of the bidirectional threaded rod 21, and a pair of vibration devices 23 are further arranged at the vertical surface outside the U-shaped conveying box 1.

[0032] In use, first according to the operation steps in Example 1, after long-term use of the U-shaped conveying box 1, the Y-shaped aggregate frame 5 needs to be disassembled first, and a small number of nuts are used to temporarily fix the Y-shaped aggregate frame 5 and the U-shaped conveying box 1. After disassembly, the lower torsion rod 22 is twisted, because the torsion rod 22 is connected with the bidirectional threaded rod 21, and the bidirectional threaded rod 21 and the rectangular mounting plate 19 are in a rotating relationship. With the continuous rotation of the bidirectional threaded rod 21, a pair of rectangular mounting plates 19 will move, and the distance between the rectangular mounting plates 19 will increase at this time. Because the distance between the pair of mounting strips 20 is less than the distance between the vertical parts of the T-shaped mounting slot before the rectangular mounting plates 19 move, and the length of the rectangular extension plate 13 and the pair of rectangular baffles 14 together is the same as the distance between the vertical parts of the T-shaped mounting slot. When the distance between the pair of rectangular mounting plates 19 continuously increases, the arc-shaped filtering structure will fall off without the restriction of the pair of mounting strips 20, and then a new one can be replaced.

[0033] The remaining structure is the same as that of Example 1.
