Description

Technical Field

[0001] The utility model relates to an agricultural fertilizer crushing device, belonging to the field of agricultural fertilizer production equipment. Background Art

[0002] Fertilizer refers to a type of substance that provides one or more essential nutrients for plants, improves soil properties and increases soil fertility levels. It is one of the material bases of agricultural production and mainly includes ammonium phosphate fertilizers, large-element water-soluble fertilizers, medium-element fertilizers, biological fertilizers, organic fertilizers, multi-dimensional field energy concentrated organic fertilizers, etc. Fertilizer is a fertilizer made by chemical or physical methods that contains one or more nutrients required for the growth of crops. In order to improve the quality of fertilizers, each raw material to be mixed must generally be crushed before preparing the fertilizer to improve the uniformity of the raw material mixing.

[0003] The traditional fertilizer crushing device has the following shortcomings: the existing fertilizer crushing equipment cannot realize both crushing and crushing at the same time, the function is relatively single, and during the crushing work, the crushing wheel and the transmission shaft are mostly fixedly connected. The crushing wheel set in this way cannot adapt to the material layer, because the material poured into the equipment will not be evenly distributed in the equipment, which will cause the material layer to be uneven. In this way, the crushing wheel will only crush the high material layer or the low material layer, and uniform crushing cannot be achieved, resulting in uneven fertilizer particles after crushing and poor crushing effect. Often, after the crushing work is completed, there are a large number of uneven particles in the crushing box, which requires people to rework. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide an agricultural fertilizer crushing device.

[0005] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0006] An agricultural fertilizer crushing device comprises a crushing box, a crushing chamber is provided inside the crushing box, a feed port is provided at the top of the crushing box, a discharge port is provided at the bottom of the side of the crushing box, an annular crushing groove is provided at the bottom of the crushing box, a crushing mechanism matched with the annular crushing groove is provided inside the crushing chamber, the crushing mechanism comprises a driving assembly and a linkage assembly, the driving assembly comprises a motor fixed at the top center of the crushing box, a motor shaft is provided at the bottom output end of the motor, the bottom end of the motor shaft passes through the crushing chamber and is connected and fixed to a rotating shell.

[0007] Furthermore, the linkage assembly includes a fixed conical toothed disc fixed at the bottom center of the crushing chamber and a plurality of rotating columns connected to the bottom of the side of the rotating shell in a uniform rotation. The fixed conical toothed disc is accommodated inside the rotating shell. A conical gear is fixed to one end of the rotating column inside the rotating shell. The conical gear is meshed with the fixed conical toothed disc.

[0009] Furthermore, the end of the rotating column penetrates into the circular hole, the toggle plate and the movable groove correspond to each other one by one, and the end of the toggle plate penetrates into the movable groove.

[0010] Furthermore, both side openings of the circular hole are provided with annular inclined surface grooves, and the crushing teeth are of trapezoidal structure.

[0011] Furthermore, the rotating shell is a bottomless structure, and limiting ring blocks are provided in the top circumferential direction and the bottom circumferential direction of the rotating shell, and limiting ring grooves matching with the limiting ring blocks are opened on the upper and lower inner walls of the crushing chamber.

[0012] Furthermore, both the feed port and the discharge port are provided with sealing plates, and the sides of the sealing plates are provided with sealing gaskets.

[0014] Beneficial effects of the utility model:

[0015] Through the design of the rolling and crushing mechanism, several rolling wheels can be driven to perform lateral and longitudinal rotational movements, so that several rolling wheels can rotate synchronously to achieve the extrusion and crushing work of the annular crushing groove, and the rotation rhythm of several rolling wheels is the same, so that several rolling wheels can evenly roll the material, thereby achieving the rolling and crushing work of the material.

[0016] Through the design of the driving component, the motor drives the rotating shell to rotate horizontally, and the rotation of the rotating shell drives several rotating columns to rotate horizontally. The rotation of the rotating column will drive the bevel gear and the toggle plate to rotate horizontally synchronously. The toggle plate will push the rolling wheel to rotate horizontally while rotating horizontally.

[0017] Through the design of the linkage component, the bevel gear will rotate along the circumferential direction of the fixed bevel toothed disc while rotating horizontally. The bevel gear will move along the fixed bevel toothed disc, thereby driving the rotating column to rotate longitudinally. The longitudinal rotation of the rotating column will drive the toggle plate to rotate. The rotation of the toggle plate will drive the longitudinal rotation of the crushing wheel by squeezing the inner wall of the movable groove, thereby making the longitudinal rotation of the crushing wheel compatible with the walking action of the crushing wheel in the annular crushing groove.

[0018] Through the design of the toggle plate, circular hole and movable groove, the rolling wheel can have a fine-tuning space, which can adapt to material layers of different thicknesses. When the rolling wheel is running, it can crush the material by its own weight, and the crushing teeth on the rolling wheel can crush the material to achieve the crushing and crushing of the material.

[0019] The cooperation between the limiting ring block and the limiting ring groove improves the rotation stability of the rotating shell.

[0020] By designing the sealing gasket, the sealing performance of both the feed port and the discharge port can be improved.

[0021] Through the design of the material guide groove, when the rolling wheel rolls and crushes the material in the annular crushing trough, the extrusion causes the material to rise, and the rising material will overflow to the material guide groove. When the rolling wheel passes, the material will fall along the inclined surface of the material guide groove into the inside of the annular crushing trough. BRIEF DESCRIPTION OF THE DRAWINGS
