Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer production, and more specifically to a fertilizer granulating mechanism. Background Art

[0002] Organic fertilizers generally go through the granulation stage. The main methods of fertilizer granulation are: extrusion method (i.e. extrusion or roller granulation), agglomeration method (i.e. disc or cylinder granulation), slurry method (i.e. granulation after high-temperature melting). Compared with chemical fertilizers of the same composition, the extrusion method is the simplest, with lower cost and price.

[0003] The extrusion method is often carried out by extruding a pair of rollers. The extrusion method is generally used to extrude powdered fertilizer containing a certain amount of water into granular fertilizer. However, the roller extrusion produces a cake formed by the bonding of multiple granular fertilizers, and it is necessary to manually break up the cake into granular fertilizers, which is time-consuming and labor-intensive. Utility Model Content

[0004] The utility model aims to provide a fertilizer granulating mechanism, which is convenient for breaking up material cakes into granular fertilizers, saving time and labor.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A fertilizer granulation mechanism comprises a box body, a feeding hopper is arranged at the top of the box body, two squeezing rollers are arranged inside the box body, a first driving motor for driving the squeezing rollers to rotate is installed outside the box body, a filter screen is arranged below the squeezing rollers, two crushing rollers are arranged between the filter screen and the squeezing rollers, a plurality of crushing rods are arranged on the crushing rollers, and a second driving motor for driving the crushing rollers to rotate is installed outside the box body.

[0007] Furthermore, the cylindrical surface of the extrusion roller is provided with a plurality of granulation cavities of the same size, the granulation cavities are densely spread on the outer cylindrical surface of the roller sleeve, and intervals are left between adjacent cavity holes.

[0008] Furthermore, the crushing rods on the two crushing rollers are arranged alternately and do not interfere with each other.

[0009] Furthermore, multiple groups of mounting components are arranged on the inner wall of the box body, and the mounting components include two mounting plates symmetrically arranged up and down, a sliding rod is fixedly connected between the two mounting plates, a frame is commonly sleeved on the sliding rods, a spring is connected between the frame and the mounting plate, the filter is arranged in the frame, and a vibration motor is installed at the bottom of the frame.

[0010] Furthermore, a rounded tray is provided below the filter screen, and a rotating motor for driving the rounded tray to rotate is installed at the bottom inner side of the box body.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] After the powdered fertilizer enters the box through the feed hopper, it is squeezed into a cake by the squeezing roller, and then the cake is broken into granular fertilizer by the breaking rod. The granular fertilizer is filtered out by the filter screen, and the fertilizer that is not broken up and still sticky is filtered on the filter screen and is further broken up by the breaking rod. The utility model is convenient for breaking the cake into granular fertilizer, saving time and labor. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] like Figure 1 and Figure 2 As shown, a fertilizer granulation mechanism comprises a box body 1, a feeding hopper 2 is arranged at the top of the box body 1, two squeezing rollers 3 are arranged on the inner side of the box body 1, a first driving motor for driving the squeezing rollers 3 to rotate is installed on the outer side of the box body 1, a filter screen 4 is arranged below the squeezing rollers 3, two crushing rollers 5 are arranged between the filter screen 4 and the squeezing rollers 3, a plurality of crushing rods 6 are arranged on the crushing rollers 5, and a second driving motor for driving the crushing rollers 5 to rotate is installed on the outer side of the box body 1.

[0017] The cylindrical surface of the extrusion roller 3 is provided with a plurality of granulation cavities of the same size. The granulation cavities are densely spread on the outer cylindrical surface of the roller sleeve, and intervals are left between adjacent cavity holes.

[0018] The crushing rods 6 on the two crushing rollers 5 are arranged alternately and do not interfere with each other.

[0019] A plurality of mounting components are arranged on the inner wall of the box body 1, and the mounting components include two mounting plates 7 symmetrically arranged up and down, a slide rod 8 is fixedly connected between the two mounting plates 7, a frame 9 is commonly sleeved on the slide rod 8, a spring 10 is connected between the frame 9 and the mounting plate 7, the filter screen 4 is arranged in the frame 9, and a vibration motor 11 is installed at the bottom of the frame 9.

[0020] A rounded tray 12 is provided below the filter screen 4 , and a rotating motor 13 for driving the rounded tray 12 to rotate is installed at the inner bottom of the box body 1 .

[0021] Working principle:

[0022] After the powdered fertilizer enters the box body 1 through the feed hopper 2, it is squeezed into a cake by the squeezing roller 3, and then the crushing roller 5 drives the crushing rod 6 to break the cake into granular fertilizer. The granular fertilizer is filtered out through the filter 4, and the fertilizer that is not broken up and still sticky is filtered on the filter 4 and is further broken up by the crushing rod 6. The vibration motor 11 drives the frame 9 and the filter 4 to vibrate to avoid clogging of the filter. The filtered granular fertilizer falls into the rounding tray 12, and the rotating motor 13 drives the rounding tray 12 to rotate. The granular fertilizer performs centrifugal rotation in the rounding tray 12 to achieve rounding and shaping of the granular fertilizer.
