[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0035] The following further describes the present invention with reference to the embodiments.

[0036] Embodiment:

[0037] A feed inspection crusher includes an outer shell 1, a crushing roller 3, a discharge port 4, a filter mechanism 5, and a vibration mechanism 6;

[0038] Inside the outer shell 1, a crushing roller 3 is installed for feed crushing. There are raised strips on the outer side of the crushing roller 3, and the crushing roller 3 is rotationally connected to the inner wall of the outer shell 1 through a shaft; there are 2 groups of crushing rollers 3, and the single crushing rollers 3 are meshed with each other. One of the crushing rollers 3 is connected to the output end of the motor, so that the crushing roller 3 can drive the other group of crushing rollers 3 to rotate, thereby crushing the feed, and using the raised strips to better crush the feed;

[0039] At the lower end of the outer shell 1, there is a discharge port 4 for discharging materials.

[0040] At the upper opening of the outer shell 1, there is also a guiding plate 2. The surface of the guiding plate 2 is inclined. By using the guiding plate 2, the size of the upper opening of the outer shell 1 is reduced, so that the poured feed can be directly guided into the crushing area of the crushing roller 3, avoiding the feed from entering the gap between the crushing roller 3 and the outer shell 1 and causing difficult crushing.

[0041] Below the crushing roller 3, a filtering mechanism 5 installed inside the outer shell 1 is provided for filtering crushed materials. At one diagonal of the outer side of the filtering mechanism 5, a vibration mechanism 6 is respectively installed for vibrating the filtering mechanism 5.

[0042] The filtering mechanism 5 includes a rectangular enclosing plate 501. At one corner of the enclosing plate 501, there is a through slot for passing through the mounting rod 601. A sieve mesh 502 is installed inside the enclosing plate 501. The longitudinal section of the enclosing plate 501 is in an "L" shape, and the height of the top surface of the enclosing plate 501 is higher than the surface of the sieve mesh 502, which can concentrate the crushed feed within the range enclosed by the enclosing plate 501 and prevent it from moving outwards.

[0043] The vibration mechanism 6 includes a mounting rod 601, a contact block 602, a fixed block 603, a supporting block 604 and a positioning block 605;

[0044] The upper end of the mounting rod 601 is connected to a rotating shaft with a torsion spring, and the contact block 602 is connected to the torsion spring, so that the contact block can rotate and reset together with the torsion spring;

[0045] The inner cross-section of the contact block 602 is inclined, and the contact block 602 is arranged in a fitting manner with the raised strips on the outer side of the crushing roller 3;

[0046] The bottom of the mounting rod 601 passes through the enclosing plate 501. The bottom end of the mounting rod 601 is installed with a supporting block 604 and is located below the sieve mesh 502. A positioning block 605 is arranged inside the supporting block 604, and the supporting block 604 and the positioning block 605 are slidably connected. The longitudinal section of the positioning block 605 is in a "T" shape, and the lower end of the positioning block 605 is installed with a fixed block 603 fixed inside the outer shell 1 to limit the moving height of the supporting block 604.

[0047] A buffer spring 606 is also arranged between the surrounding plate 501 and the supporting block 604 and is installed on the supporting block 604. It is used to buffer and release potential energy, can slow down the collision between the surrounding plate 501 and the supporting block 604 when the surrounding plate 501 descends, and when the surrounding plate 501 descends and contacts the buffer spring 606, the buffer spring 606 deforms and then resets, thereby pushing the surrounding plate 501 to continue moving upward until the kinetic energy conversion is completed, so that the screen 502 can generate vibrations at a certain frequency and improve the screening effect of the vibrating screen.

[0048] Specifically, during the rotation of the crushing roller 3, since the contact block 602 fits with the protruding strip on the outer side of the crushing roller 3, the rotation of the crushing roller 3 drives the mounting rod 601 to move upward, so that the supporting block 604 lifts the filtering mechanism 5. Subsequently, after the contact block 602 moves to a certain height, the supporting block 604 is restricted by the positioning block 605 and no longer moves upward. The continuous rotation of the crushing roller 3 can only drive the contact block 602 to rotate with the mounting rod 601, so that the contact block 602 disengages from the fitting with the strip structure on the outer side of the crushing roller 3, and the supporting block 604 moves downward under the influence of its own gravity and collides with the positioning block 605, causing the screen 502 in the filtering mechanism 5 to vibrate, vibrating the feed crushing particles on the upper side of the screen 502, driving the vibrating screen by relying on the rotation of the crushing roller 3, and reducing the number of motors; after the screen 502 falls, the contact block 602 resets under the action of the torsion spring and is driven by the crushing roller 3 again to move the filtering mechanism 5, and so on, realizing the vibrating screening effect on the material.

[0049] In addition, auxiliary buffer devices are respectively arranged at the other two diagonal corners of the surrounding plate 501.

[0050] The auxiliary buffer device includes an L-shaped positioning rod 7 and a support body 8.

[0051] Through grooves are respectively arranged at the other two diagonal corners of the surrounding plate 501.

[0052] The bottom of the vertical rod in the L-shaped positioning rod 7 passes through the through groove, and the bottom of the L-shaped positioning rod 7 is connected to the support body 8, and the support body 8 is connected to the housing 1.

[0053] A buffer spring 606 is also arranged between the surrounding plate 501 and the support body 8 and is installed on the support body 8.

[0054] In this solution, the function of setting the above-mentioned auxiliary buffer device is to guide and buffer the up and down movement of the filtering mechanism 5.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
