Description

Technical Field

[0001] The utility model relates to the technical field of water-soluble fertilizer production, in particular to a water-soluble fertilizer solid grinder. Background Art

[0002] Water-soluble fertilizer is a multi-component compound fertilizer that can be completely soluble in water. It can dissolve quickly in water, is more easily absorbed by crops, and has a relatively high absorption and utilization rate. More importantly, it can be used in facility agriculture such as sprinkler and drip irrigation to achieve water-fertilizer integration and achieve the effect of saving water, fertilizer and labor.

[0003] After searching, it was found that the publication number is CN220126488U, and the name is a water-soluble fertilizer solid raw material grinder. The application proposes that in the relevant technology, water-soluble fertilizers need to be ground multiple times during the production process to grind the solid particles finely for later mixing and dissolution with water. The application number is 201920413847.0, which discloses a multi-stage crusher for granular fertilizer raw materials. By sequentially arranging a first grinding body, a grinding disc, and a second grinding body, the secondary crushing of the fertilizer raw materials is achieved, thereby improving the crushing effect of the raw materials to ensure the quality of fertilizer mixing.

[0004] The existing technology has the following problems:

[0005] 1. The aggregate frame needs to be moved after it is full. During the movement, grinding and discharging cannot be carried out synchronously. It is necessary to wait for the aggregate frame to move and reset before grinding and discharging can be carried out. The waiting time is long, which affects the continuous production efficiency, and it is difficult for the aggregate frame to stabilize the amount of each packaging. Manual weighing and packaging are required in the later stage, which is very troublesome and affects the work efficiency. Further improvements can be made. At the same time, the application adopts a multi-stage crushing and screening structure, which is too complicated, and the filter screen is blocked and inconvenient to clean, which affects the work efficiency and convenience of use. Further improvements can be made.

[0006] To this end, we proposed a water-soluble fertilizer solid grinder to solve the above disadvantages. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] (1) The utility model adopts a grinding head and a grinding column. When grinding water-soluble fertilizer solids, the water-soluble fertilizer solids can be put into the grinding tank, and the driving motor drives the main shaft to rotate, thereby driving the grinding head and the grinding column to rotate, grinding the water-soluble fertilizer solids that enter the grinding liner and between the grinding head and the grinding column to form powder. During the process of the grinding head rotating and grinding, the cylinder continuously performs a lifting operation to push the lifting platform and the grinding head and the grinding column to move up and down. The grinding head moves up and down to hammer the water-soluble fertilizer solids between the grinding head and the grinding liner, thereby grinding and crushing, thereby improving the grinding and crushing efficiency.

[0018] (2) The utility model adopts a belt scale and a packaging frame. The ground water-soluble fertilizer solids fall out of the bottom barrel and enter the belt scale for weighing. When the packaging weight is reached, the belt scale stops running, and the stepping conveyor belt rotates, driving the empty packaging frame to move to the bottom of the belt scale discharge end, thereby completing continuous weighing and packaging, which significantly improves work efficiency. At the same time, the stepping conveyor belt drives the packaging frame to move, which is convenient for transporting the water-soluble fertilizer solids and saves the trouble of manual handling. When the packaging frame runs to one end of the stepping conveyor belt, the packaging frame naturally flips over through the rotating shaft to pour out the water-soluble fertilizer solids to be packaged, which greatly facilitates the staff to carry out quantitative packaging and significantly improves production efficiency and convenience of use.

During the rotation and grinding of the grinding head 2, the cylinder 16 continuously performs a lifting operation to push the lifting platform 13 and the grinding head 2 and the grinding column 4 to move up and down. The grinding head 2 moves up and down to hammer the water-soluble fertilizer solids between the grinding head 2 and the grinding liner 3, thereby grinding and crushing the water-soluble fertilizer solids, thereby improving the grinding and crushing efficiency. During the up and down movement of the grinding column 4, the distance between the grinding column 4 and the bottom cylinder 5 does not change, and the water-soluble fertilizer solid powder that does not meet the particle size requirements cannot fall out of the bottom cylinder 5, thereby eliminating the trouble of screening and significantly simplifying.

At the same time, the stepping conveyor belt 9 drives the packaging frame 10 to move, which is convenient for transporting water-soluble fertilizer solids and eliminates the trouble of manual handling. When the packaging frame 10 runs to one end of the stepping conveyor belt 9, the packaging frame 10 is naturally flipped through the rotating shaft 12 to pour out the water-soluble fertilizer solids to be packaged, which greatly facilitates the staff to carry out quantitative packaging and significantly improves the production efficiency and convenience of use.
