[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The cross-contamination prevention conveying equipment for composite premixes for pigs exemplified in the present invention reduces the impact between different types of premixes by separately sealing and conveying premixes of different types and batches, thereby ensuring the quality of the composite premixes, and controlling the air supply component to convey airflow into the air supply duct. The airflow in the air supply duct enters the conveying duct through the connecting pipe. The airflow assists the premixes to move in the conveying duct, thereby preventing the premixes from accumulating and clogging in the conveying duct.

[0016] 2. The cross-contamination prevention conveying equipment for composite premixes for pigs exemplified in the present invention can control the electric heating plate to work if the internal water content is high and the humidity is high when producing biological fermentation premixes. The temperature control box can heat the connecting pipe under the action of heat conduction of the insulation liquid. The airflow is heated when it enters the conveying pipeline through the connecting pipe. It can be used for drying the premixes, which is convenient for the preparation of composite premixes. When the moisture content of the premixes is low and the dust is too large, the water pump group is controlled to pump water from the outside, and the water flow drawn by the water pump group enters the water spray box through the water inlet pipe and is sprayed out through the atomizing nozzle on the water spray box. After that, the airflow transported by the air supply component drives the water mist into the conveying pipeline to mix with the premixes, which is convenient for the humidification treatment of the premixes.

[0017] 3. The cross-contamination prevention conveying equipment for composite premixes for pigs in the example of the present invention controls the telescopic cylinder to move the arc-shaped constraint plate, so that the arc-shaped constraint plate squeezes the conveying hose and deforms it inward, and then drives the annular movable plate to move through the driving assembly to move the arc-shaped constraint plate to adjust the extrusion position of the conveying hose, so as to facilitate the movement of the premix in the conveying hose and realize the horizontal conveying of the premix. In addition, the diameter of the conveying hose is reduced after being squeezed and shrunk by the arc-shaped constraint plate, and the airflow can be used for condensation of the airflow when passing through this position, thereby increasing the airflow velocity. If the premix accumulates in the conveying hose, it can be cleared in this way.

[0018] 4. The cross-contamination prevention conveying equipment for composite premixes for pigs exemplified by the present invention, when the driving motor drives the driving screw to rotate forward to make the pushing component feed, the driving screw drives the spring in the clockwork box to deform through the one-way transmission mechanism, and applies force to the spring to make it rotate and shrink. When the driving motor drives the driving screw to rotate reversely to reset the pushing component, the one-way transmission mechanism disconnects the driving screw from the clockwork box, which is convenient for the use of the clockwork box. After the spring in the clockwork box is contracted by force, the spring recovers its deformation due to its own elasticity. During this process, the spring in the clockwork box drives the output shaft to rotate, and the output shaft drives the toothed disc to rotate through the gear. When the premix passes through the crushing hole, the rotating toothed disc and the stationary crushing disc apply force to the premix to crush it. The setting of the clockwork box enables the gear to rotate continuously for a long time, ensuring that the toothed disc and the crushing disc continuously crush the premix. Because the pushing component also operates continuously, the driving screw can indirectly apply force to the clockwork box, further extending the rotation time of the clockwork box driving gear, which is convenient for the use of the conveying equipment.

[0019] 5. In the example of the present invention, in the anti-cross-contamination conveying equipment for composite premixes for pigs, after the conveying pipeline completes the conveying of the premixes, the switch valve on the connecting pipe is opened, and the water pump group and the air supply component are controlled to work. The air supply component carries water mist when conveying the airflow to the conveying pipeline, which is convenient for cleaning the inside of the conveying pipeline. During the cleaning process, the sampling box collects clean water. The cleaning quality in the conveying pipeline can be judged according to the cleanliness of the water collected in the sampling box. When the cleaning is completed, the water pump group is turned off and the electric heating plate is controlled to work, so that the air supply component conveys hot air into the conveying pipeline, which is convenient for drying the conveying pipeline and preventing water droplets from adhering to the conveying pipeline for a long time to breed bacteria.
