[0032] like Figure 1-4 As shown, the present invention proposes a fertilizer processing pretreatment mechanism, comprising a processing chamber 1 and a feeding port 3 located on the processing chamber 1.

[0033] The processing chamber 1 is provided with a crushing element 6 for crushing the material;

[0034] The crushing part 6 includes two drive motors 61 fixedly installed on one side of the processing chamber 1. The output shaft of the drive motor 61 is fixedly connected to a connecting shaft 63 with one end passing through and extending to the inside of the processing chamber 1.

The inner wall of the processing chamber 1 is slidably connected with a support frame 48, and the inner side of the support frame 48 is fixedly connected with a screen 415. The inner side of the support frame 48 is fixedly connected with a discharge plate 414 located below the screen 415, and the lower end of the discharge plate 414 is fixedly connected with a conical frame 411. The inner side of the conical frame 411 is provided with a material guide cylinder 43 with one end passing through the discharge plate 414 and the screen 415 in sequence. A conveying paddle 413 located on the inner side of the material guide cylinder 43 is fixedly installed on the outer side of the rotating shaft 42, and a material guide hole 412 is provided on the material guide cylinder 43.

[0038] It should be noted that the screen 415 is concave in shape, so that after the screen 415 screens the material, unqualified material can slide towards the concave part of the screen 415. There are a plurality of guide holes 412, which are distributed in an annular shape on the guide barrel 43 and are located above the screen 415. Unqualified material is guided into the guide barrel 43 through the guide holes 412.

A through hole connected to the discharge hole 47 is opened on the side of the support frame 48 close to the discharge hole 47. After the qualified material falls onto the discharge plate 414, it is discharged from the processing bin 1 through the inclined discharge plate 414, the discharge hole 47 and the through hole.

[0041] In an optional embodiment, the material guide cylinder 43 is provided with a material guide member for guiding the material;

[0042] The material guide member includes a material guide plate 44 having one end fixedly connected to the upper end of the material guide cylinder 43.

The material guide plate 44 is trapezoidal.

[0043] It should be noted that the guide troughs 46 on one side and the other side of the guide plate 44 are located between the two crushing rollers 62 .

[0044] In this embodiment, the guide grooves 46 on one side and the other side of the guide plate 44 can guide the material conveyed upward by the conveying paddle 413 to be crushed again between the two crushing rollers 62 after being blocked by the baffle 45.

[0045] In an optional embodiment, a support member for supporting the support frame 48 is provided between the support frame 48 and the processing chamber 1;

[0046] The support member includes a limit block 410 fixedly connected to the outside of the support frame 48. A rectangular groove located outside the limit block 410 is opened on the side of the processing chamber 1 close to the support frame 48. A telescopic rod 49 is fixedly connected between the limit block 410 and the rectangular groove;

[0047] The telescopic rod 49 consists of a sleeve and a slide rod that slides within the sleeve. The slide rod has a T-shaped end located inside the sleeve, and its other end extends through and to the outside of the sleeve, where it is fixedly connected to a stop block 410. A spring is fixedly connected between the end of the slide rod located inside the sleeve and the inside of the sleeve.

[0048] In this embodiment, during the process of supporting the support frame 48 through the limit block 410 and the telescopic rod 49 located in the rectangular groove, the vibrating support frame 48 can stably telescope and vibrate through the limit block 410 and the telescopic rod 49.

[0049] In an optional embodiment, a driving member for driving the support frame 48 is provided on the conical frame 411 and the rotating shaft 42;

[0050] The driving member includes a protrusion 418 fixedly connected to the outer side of the conical frame 411 , a connecting rod 416 fixedly connected to the lower end of the rotating shaft 42 , and a pulley 417 rotatably connected to the end of the connecting rod 416 .

[0051] It should be noted that there are several protrusions 418, which are distributed in a circular shape and equidistantly on the outside of the conical frame 411. The connecting rod 416 is L-shaped, and there are three connecting rods 416. The three connecting rods 416 are distributed in a circular shape and equidistantly on the rotating shaft 42. The pulley 417 is located between the two protrusions 418.

[0052] In this embodiment, the rotating shaft 42 driven by the servo motor 41 can follow the rotation through the pulley 417 on the connecting rod 416 during the rotation process, and the rotating pulley 417 can drive the conical frame 411, the support frame 48, the screen 415 and the discharge plate 414 to follow the vibration by repeatedly squeezing the protrusion 418 during the process of contact with the protrusion 418.

[0053] The working principle in the above embodiment is:

[0054] When the driving motor 61 is started and drives the two sets of crushing rollers 62 to rotate toward the opposite side through the connecting shaft 63, the servo motor 41 can be started to drive the rotating shaft 42 and the conveying paddle 413 to rotate in the positive direction, and then the fertilizer material to be pretreated is fed through the feeding port 3, crushed by the rotating crushing roller 62, and then falls onto the screen 415. When the rotating rotating shaft 42 repeatedly squeezes the protrusion 418 through the pulley 417 on the connecting rod 416, it can drive the support frame 48, the screen 415 and the discharge plate 414 to vibrate, thereby vibrating and screening the material. Finally, qualified materials will fall onto the discharge plate 414, and then be discharged through the through hole on the support frame 48 and the discharge hole 47 on the processing bin 1, while unqualified materials will slide through the guide hole 412 to the material in the guide barrel 43, and be re-conveyed to the guide plate 44 by the rotating conveying paddle 413, and guided to the left and right sides of the crushing rollers 62 for further crushing. When no qualified materials are discharged, the servo motor 41 can be started in reverse to drive the rotating shaft 42 and the conveying paddle 413 to rotate in the opposite direction, so that the materials that cannot be completely crushed and screened can be guided through the guide barrel 43.

[0055] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
