[0002] Compound fertilizer has the advantages of high nutrient content, few by-products and good physical properties. There are many methods to produce compound fertilizer. When the raw materials are agglomerated and granulated, they are prone to caking. The agglomerated compound fertilizer will affect the fertilizer effect after fertilization in the farmland when used, causing uneven fertilization.

[0003] In the production process, the existing raw materials are not completely crushed due to the raw materials being too large, resulting in substandard product quality. Most of the raw materials are crushed using a crusher for single and single crushing, which cannot avoid the problem of raw materials not being crushed, thereby reducing the crushing effect of the raw materials.

In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0021] Example: See Figure 1 — Figure 4 The utility model provides a technical solution: a raw material crushing equipment for compound fertilizer production, including an equipment body 1, a feed trough 2 is opened on the top of the equipment body 1, a feed hopper 3 is arranged in the inner cavity of the feed trough 2, an L-shaped connecting plate 4 is arranged on the left side of the equipment body 1, a servo motor 5 is arranged on the left side of the L-shaped connecting plate 4, a support rod 6 is rotatably installed on the top of the right side of the L-shaped connecting plate 4 through a bearing, a first synchronous pulley 11 and a second synchronous pulley 12 are respectively arranged on the output shaft of the servo motor 5 and the middle of the support rod 6, a first connecting rod 13 and a second connecting rod 14 are rotatably installed on both sides of the middle part of the equipment body 1 through bearings, a discharge pipe 25 is arranged in the middle of the bottom of the equipment body 1, and a valve 26 is arranged in the middle of the discharge pipe 25.

[0022] The feed hopper 3 and the two first crushing rollers 9 are arranged on the same horizontal line in a vertical shape.

[0023] The output shaft of the servo motor 5 and the right side of the support rod 6 are respectively provided with a first gear 7 and a second gear 8 which mesh with each other. The output shaft of the servo motor 5 and the right side of the support rod 6 are both provided with a first crushing roller 9 .

[0024] In this embodiment, the output shaft of the servo motor 5 drives the first gear 7 to rotate. Since the first gear 7 and the second gear 8 are meshed with each other, the support rod 6 can be rotated synchronously through the bearing when the second gear 8 is driven to rotate, thereby driving the two first crushing rollers 9 to rotate synchronously in opposite directions to crush the raw materials. When the feed hopper 3 and the two first crushing rollers 9 are on the same vertical horizontal line, it can be ensured that the raw materials can be crushed when they enter.

[0025] Among them, the third synchronous pulley 15 and the fourth synchronous pulley 16 are respectively arranged in the middle of the first connecting rod 13 and the second connecting rod 14, the first synchronous pulley 11, the third synchronous pulley 15, the second synchronous pulley 12 and the fourth synchronous pulley 16 are respectively equipped with the first belt 17 and the second belt 18, and the second crushing roller 19 is arranged on the right side of the first connecting rod 13 and the second connecting rod 14.

[0026] In this embodiment, the output shaft of the servo motor 5 and the support rod 6 rotate to drive the first synchronous pulley 11 and the second synchronous pulley 12 to rotate, and the first connecting rod 13 and the second connecting rod 14 are driven by the first belt 17 and the second belt 18 and the third synchronous pulley 15 and the fourth synchronous pulley 16 to rotate synchronously through the bearings, so that the two second crushing rollers 19 can rotate synchronously in opposite directions to perform double and effective crushing of the compound fertilizer raw materials, thereby improving the effect of raw material crushing.

[0027] Among them, two electric telescopic rods 22 are equidistantly arranged on the right side of the bottom of the L-shaped connecting plate 4, and a U-shaped seat 23 is arranged at the output end of the two electric telescopic rods 22. A grinding roller 24 is rotatably installed in the inner cavity of the U-shaped seat 23 through a rotating rod.

[0028] A square plate 20 is provided at the bottom of the inner cavity of the device body 1 and is arranged at an angle of 45 degrees. A plurality of drain grooves 21 are opened on the right side of the top of the square plate 20 .

[0029] In this embodiment, the U-shaped seat 23 is driven to move by the output ends of the two electric telescopic rods 22, and the grinding roller 24 is driven to contact the square plate 20 during the movement. The rotating rod rotates back and forth in the inner cavity of the U-shaped seat 23, and the compound fertilizer raw materials that fall on the square plate 20 after crushing are reciprocated and rotated during rotation. After grinding, they fall to the bottom of the inner cavity of the equipment body 1 through the leakage groove 21, so that they can be polished again after crushing, ensuring that the raw materials have a uniform effect after being crushed.

[0030] Among them, support legs 27 are arranged around the bottom of the device body 1, and anti-slip seats 28 are arranged at the bottom of the support legs 27, and the bottom is frosted.

[0031] In this embodiment, by setting the bottom of the anti-slip seat 28 to be frosted, the friction resistance between the support leg 27 and the working surface can be increased, preventing the support leg 27 from moving autonomously when the equipment body 1 is working, thereby improving the stability of the device when in use.

[0032] Working principle: First, the output shaft of the servo motor 5 and the support rod 6 rotate to drive the first synchronous belt pulley 11 and the second synchronous belt pulley 12 to rotate, and the first belt 17 and the second belt 18 and the third synchronous belt pulley 15 and the fourth synchronous belt pulley 16 drive the first connecting rod 13 and the second connecting rod 14 to rotate synchronously through the bearing, so that the two second crushing rollers 19 can rotate synchronously in opposite directions, and when the output shaft of the servo motor 5 and the support rod 6 rotate, the first synchronous belt pulley 11 and the second synchronous belt pulley 12 are driven to rotate, and the first belt 17 and the second belt 18 and the third synchronous belt pulley 15 and the fourth synchronous belt pulley 16 drive the first connecting rod 13 and the second connecting rod 14 to rotate synchronously through the bearing, so that the two second crushing rollers 19 can follow the two first crushing rollers 9 synchronously After the raw materials are crushed, they are put into the main body 1 of the equipment through the feed hopper 3 in the feed trough 2. When the raw materials enter the main body 1, they are crushed doubly and effectively by the two first crushing rollers 9 and the two second crushing rollers 19, thereby improving the crushing effect of the raw materials. After the raw materials are crushed, they fall onto the square plate 20. At this time, the output ends of the two electric telescopic rods 22 drive the U-shaped seat 23 to move, and drive the grinding roller 24 to contact the square plate 20 during the movement. The rotating rod rotates back and forth in the inner cavity of the U-shaped seat 23. When rotating, the compound fertilizer raw materials that have been crushed and fallen onto the square plate 20 are reciprocatingly rotated and polished. After grinding, they fall to the bottom of the inner cavity of the main body 1 of the equipment through the leakage groove 21, and finally, the discharge pipe 25 is opened by rotating the valve 26 to discharge them out of the main body 1 of the equipment.

[0033] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
