Description

Technical Field

[0001] The utility model relates to the field of screening and drying equipment, in particular to a screening and drying machine used for fertilizer production. Background Art

[0002] Chemical fertilizers, also known as fertilizers for short, generally refer to fertilizers made by chemical methods or from ore, which are processed and contain one or more nutrients needed for the growth of crops. They are also called inorganic fertilizers. During the production process of chemical fertilizers, they are usually granulated by a granulator and then transported to a screening dryer for drying and screening.

[0003] At present, the Chinese utility model with the announcement number CN219560370U discloses a raw material drying and screening device, which belongs to the technical field of magnesium carbon brick preparation equipment, wherein the device comprises a screening box and a dryer, the screening box and the dryer are connected through a ventilation pipe, the inner wall of the screening box is fixedly connected with a support seat, the support seat is overlapped with an outer screening cylinder, the outer screening cylinder is integrally connected with an inner screening cylinder, one side of the inner screening cylinder is provided with an open groove, one end of the ventilation pipe is connected with the inner screening cylinder through a rotary joint, and the outer surface of the outer screening cylinder is fixedly connected with teeth. Under the joint action of the sealing cover, the inner screening cylinder, the outer screening cylinder, the second motor and the gear, the raw materials put into the inner screening cylinder can be screened, and under the joint action of the dryer and the ventilation pipe, the raw materials can be dried while screening, which saves time and improves work efficiency compared with the two processes of screening and drying.

[0004] To sum up, although the screening and drying device can achieve the purpose of screening and drying, there are still certain problems when using it. For example, the screening mesh of the screening and drying device is fixed, and the screening mesh plate of the screening and drying device is installed inside the equipment. When the screening size needs to be replaced with other sizes, the equipment shell needs to be disassembled as a whole to replace the internal mesh plate, which is more troublesome. At the same time, the screening and drying device lacks an anti-blocking structure when in use. When the fertilizer particles are screened, some fertilizer particles are easily stuck in the mesh holes of the screening mesh plate, causing blockage of the screening mesh holes and affecting the normal screening work. Utility Model Content

[0016] The utility model is further configured as follows: a fixing seat is fixedly sleeved on the surface of the driving motor, and the fixing seat is bolted to the second feeding seat.

[0017] The above technical solution is adopted to limit and fix the driving motor.

[0018] The utility model is further configured as follows: one end of the connecting rod and the surface of the rotating rod are both fixedly sleeved with a transmission wheel, and the two transmission wheels are connected through a belt transmission.

[0019] The above technical solution is adopted to facilitate driving the connecting rod to rotate.

[0020] The utility model is further configured as follows: the bottom of the collecting hopper is connected with a discharge pipe, and a valve is installed on the surface of the discharge pipe.
