[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 to Figure 3In an embodiment of the utility model, a feed processing and crushing device includes a shell 1, an inner cavity of the shell 1 is fixedly connected with a feed port 3 penetrating to the top of the shell 1, both ends of the bottom of the feed port 3 are fixedly connected with bellows 4, the bottom ends of the two bellows 4 are fixedly connected to the two ends of the outer periphery of a screen cylinder 5, both ends of the screen cylinder 5 are fixedly connected with fixed disks 6, and a driving mechanism is installed at one end of the fixed disk 6; the outside of the shell 1 is provided with a main shaft 2 penetrating through the shell 1, the fixed disk 6, the screen cylinder 5 and extending to the outside of the other end of the shell 1, the main shaft 2 is rotatably connected to the shell 1 and the fixed disk 6, and the outer wall of the main shaft 2 is located between the inner wall of the shell 1 and the outside of a fixed disk 6 and is interference-fitted with a half gear 8.

[0021] In this embodiment: first, the feed to be crushed is added into the screen drum 5 through the feed inlet 3, and then the driving connection connected to the main shaft 2 is started, and the main shaft 2 drives the crushing hammer fixed on its periphery to rotate at high speed, and the high-speed rotating crushing hammer hammers the feed to form a crushing effect;

[0022] When the main shaft 2 rotates, the main shaft 2 synchronously drives the half gear 8 to rotate, and the rotating half gear 8 drives the driving mechanism to operate, and the driving mechanism can drive the fixed plate 6 connected thereto to rotate and swing back and forth. The reciprocating rotating and swinging fixed plate 6 drives the screen drum 5 to move synchronously, and the reciprocating rotating and swinging screen drum 5 can form a vibration effect on the material accumulated in its inner cavity, so as to enable the material to fully contact with the high-speed rotating breaker, thereby improving the crushing efficiency of the material, reducing the residual material, and the qualified crushed material is moved out through the screen drum 5.

[0023] Please refer to Figure 2 and Figure 3 The driving mechanism includes a fixed rod 10 fixedly connected to the two side plates of the outer shell 1, and the outer wall of the fixed rod 10 is slidably connected with a double-sided rack 9. Springs 11 are fixedly connected between the two ends of the double-sided rack 9 and the inner wall of the side plate of the outer shell 1. The driving mechanism also includes a full gear 12 meshed with the double-sided rack 9 below, and the full gear 12 is rotatably connected to an end plate of the outer shell 1. A hollow ring 7 protruding outward is integrally formed at one end of the outer side of a fixed disk 6, and an inner tooth 13 meshing with the full gear 12 is integrally formed below the inner circumference of the hollow ring 7.

[0024] In this embodiment: when the half gear 8 rotating with the main shaft 2 meshes with the tooth block above the double-sided rack 9 during the rotation process, the double-sided rack 9 slides axially along the outer wall of the fixed rod 10 under the push, at this time, one spring 11 is stretched and the other spring 11 is compressed. When the half gear 8 and the double-sided rack 9 are misaligned, the two springs 11 are reset;

[0025] When the double-sided rack 9 performs the above-mentioned action, the gear block at the bottom thereof drives the full gear 12 to reciprocate and rotate, and the reciprocating full gear 12 drives the hollow ring 7 to reciprocate and rotate through the inner teeth 13, thereby realizing the reciprocating and rotating action of the screen drum 5;

[0026] Since there is a certain gap between the breaker hammer and the inner wall of the screen drum 5, the breaker hammer is prevented from contacting the inside of the screen drum 5 during high-speed rotation and causing damage to the screen drum 5. Therefore, some incompletely crushed materials will be located there, resulting in insufficient material crushing efficiency and material residue. The reciprocating rotation and swing of the screen drum 5 can cause the incompletely crushed materials in this part to move and achieve sufficient crushing. At the same time, the screen drum 5 in this action has the effect of shaking and screening, and can quickly export the qualified crushed materials.

[0027] Please refer to Figure 2 The thickness of the full gear 12 is equal to the sum of the thicknesses of the double-sided rack 9 and the inner teeth 13, and the double-sided rack 9 and the inner teeth 13 are offset in the upper and lower positions.

[0028] In this embodiment, the double-sided rack 9 and the inner teeth 13 are staggered up and down to avoid the double-sided rack 9 from moving in an interfering manner during the reciprocating movement.

[0029] Please refer to Figure 3 The outer periphery of the main shaft 2 is located in the inner cavity of the screen drum 5 and multiple groups of breaking hammers are installed, and one end of the main shaft 2 is connected to the driving motor.

[0030] In this embodiment, by starting the driving motor, the driving motor drives the breaker hammer to rotate at high speed through the main shaft 2, thereby effectively crushing the material.

[0031] Please refer to Figure 2 and Figure 3 , the screen drum 5 has a multi-mesh structure.

[0032] In this embodiment: it is convenient to export the crushed qualified materials.

[0033] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
