[0038] Referring to Figure 1 , Figure 5 and Figure 6The anti-blocking mechanism comprises a motor 4 and a plurality of support columns 3, both of which are fixedly connected to the top of the base 5. The output end of the motor 4 is fixedly connected with a rotating disc 26, the top of which is provided with an annular groove 28. A plurality of protrusions 27 are fixedly connected inside the annular groove 28. A plurality of connecting columns 25 are slidingly connected inside the annular groove 28.

The plurality of connecting columns 25 penetrate through the limiting plate 24 and are slidingly connected inside it. The bottom of the rotating disc 26 is slidingly connected to the top of the support column 3. The discharge plate 2 is slidingly connected between the plurality of baffles 6. The motor 4 is the driving source of the anti-blocking mechanism. Its rotary motion drives the rotating disc 26 to rotate, thereby triggering the operation of the entire anti-blocking system. The support column 3 is fixed to the top of the base 5, providing stable support for the rotating disc 26 and allowing the rotating disc 26 to slide on its top. The rotating disc 26 is connected to the output end of the motor 4 and is the core component of power transmission.

The annular groove 28 is arranged on the top of the rotating disc 26 and is used to accommodate the connecting column 25. The plurality of protrusions 27 inside it realize the up-and-down sliding of the connecting column 25, thereby generating vibration. The protrusions 27 are fixed inside the annular groove 28. With the rotation of the rotating disc 26, the connecting column 25 slides up and down the protrusions 27, generating periodic up-and-down motion and transmitting vibration force. The connecting column 25 is slidingly connected inside the annular groove 28, with one end fixed to the discharge plate 2 and the other end in contact with the protrusions 27 inside the annular groove 28. Through up-and-down motion, vibration force is transmitted to the discharge plate 2. The discharge plate 2 is used to receive the processed material in the feed tank 1 and prevent the material from accumulating on its surface through the vibration force transmitted by the connecting column 25, ensuring smooth flow of the material. The limiting plate 24 is fixed in the middle of the plurality of baffles 6 and is used to limit the movement range of the connecting column 25, preventing the connecting column 25 from deviating from the designed track due to large amplitude oscillation, and ensuring the safety and stability of the system operation. The baffle 6 is located on the top of the base 5 and is used to surround the discharge plate 2, limiting the overflow and scattering of the material, and ensuring that the material is concentrated above the discharge plate 2. The base 5 is the basic structure of the entire anti-blocking mechanism and provides stable support for all components.

[0039] Working principle: First, put various ingredients into the feed tank 1. Under the drive of the motor 2, the main crushing roller 29 inside the feed tank 1 begins to rotate, and through the linkage of the driving wheel 9 and the driven wheel 12, each auxiliary crushing roller 11 also operates, crushing and shearing the various ingredients in the feed tank 1, and simultaneously achieving uniform mixing. The processed material finally falls on the discharge plate 2. The entire process is efficient and fast, effectively simplifying the complicated steps of mixing and shearing in traditional processes, and greatly improving work efficiency.

[0040] Then, the motor 4 is started to drive the rotating disc 26 to rotate on the supporting column 3. The rotation of the rotating disc 26 drives the connecting column 25 to move up and down on the protrusion 27 in the annular groove 28, thereby realizing the vibration of the discharge plate 2. This design effectively prevents the accumulation of the ingredients on the discharge plate 2, ensures the smooth flow of the materials, and further improves the work efficiency.

[0041] When the equipment is running for a period of time and the driving wheel 9 and the driven wheel 12 need to be lubricated, the electromagnetic one-way valve 20 is opened. When the eccentric wheel 15 on the driven wheel 12 contacts the push rod 16, the push rod 16 pushes the piston 17 to move forward; and when the eccentric wheel 15 leaves, the spring 18 makes the piston 17 reset. Through this reciprocating action, the lubricating oil in the oil tank 13 is sucked into the hollow shell 23 and delivered to the top of the driving wheel 9 through the oil outlet pipe 22, and is uniformly sprayed on the driving wheel 9 and the plurality of driven wheels 12. This automatic lubrication system design eliminates the tedious operation of regular manual lubrication by workers, effectively prevents the gears from rusting due to long-term use, and greatly improves the running efficiency and stability of the equipment.

[0042] Finally, it should be noted that: the above is only the preferred embodiment of the present application, and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
