Description

Technical Field

[0001] The utility model belongs to the technical field of teaching aids for moral and social courses, and specifically relates to a controlled-release fertilizer granulating device. Background Art

[0002] A granulator is a device that granulates some powders. It is an important equipment for fertilizer production. By granulating fertilizers, it is convenient for farmers to use fertilizers, thereby increasing the output of agricultural products. With the development of science and technology, granulator equipment is also constantly improving. Granulators are needed in the production of inorganic composite membrane controlled-release fertilizers. Existing granulators often use extrusion devices to extrude controlled-release fertilizers from a perforated plate for granulation. Although this device can granulate quickly, one end of the perforated plate is unobstructed, resulting in the extruded controlled-release fertilizer particles to be loose and easy to loosen and fall off.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a controlled-release fertilizer granulating device, comprising a table body, a shell is arranged on the upper end surface of the table body, a perforated plate and a pressing roller are arranged inside the shell, the pressing roller is connected to a rotating shaft, the rotating shaft is driven to rotate by a motor, a movable scraper is arranged on the lower side of the perforated plate, a liftable bottom baffle is arranged on the lower side of the scraper, a groove is arranged on the bottom baffle, and the groove matches the scraper;

[0005] A shaft sleeve is sleeved on the rotating shaft, a notch is set on the shaft sleeve on one side of the scraper, one end of the scraper is placed in the notch, a column is also set in the notch, the column passes through the scraper, and a spring is sleeved on the column, a thin section is set on the rotating shaft, a bayonet is set on the lower side of the thin section, and the inner end of the scraper is clamped in the bayonet.

[0006] Preferably, a discharge nozzle is provided on one side of the shell.

[0007] Preferably, a lifting plate is provided at the lower side of the shell, the lifting plate is connected to one end of a cylinder, the cylinder is provided at one side of the shell, and the lifting plate is connected to a bottom baffle through a connecting rod.

[0008] Preferably, the edge of the lifting plate slides through a guide rod, and the guide rod is fixed to the housing.

[0009] Preferably, pulleys are provided at one end of the rotating shaft and the motor, and the pulleys are connected by a transmission belt.

[0010] Preferably, a sealing plate is arranged in the groove, and a spring is arranged at the lower side of the sealing plate.

[0011] The technical effects and advantages of the utility model are as follows: the controlled-release fertilizer granulating device can block the lower end of the perforated plate during the granulation process by arranging a bottom baffle. During granulation, the lower end is blocked, which can make the lower end more solid and tight, reduce the looseness and shedding of fertilizer, and improve the integrity of fertilizer. In addition, the linkage between the scraper and the bottom baffle is cleverly designed to ensure the scraper's function of normally scraping off the fertilizer. BRIEF DESCRIPTION OF THE DRAWINGS
