The small bevel gear on the worm rotates to drive the large bevel gear to rotate, and the large bevel gear drives the other small bevel gears to rotate, so that the other worms drive the worm gears to rotate, and then the rotating shafts can rotate simultaneously, driving the high-pressure nozzles to rotate simultaneously. When the high-pressure nozzles face the inner wall of the mixing cylinder, the inner side wall of the mixing cylinder can be flushed. When the high-pressure nozzles face the stirring rods, the stirring rods can be flushed. When the high-pressure nozzles face down, the bottom inner wall of the mixing cylinder can be flushed.

[0013] A forming process of a forming device for fireproof and flame-retardant straw floors specifically includes the following steps: Step 1: Pour the straw from which dust, stones, withered leaves and other sundries have been removed into the crushing box. The two crushing rollers rotate to crush the straw. After crushing, it is convenient to mix evenly with the flame retardant liquid. The crushed straw enters the mixing cylinder through the feeding pipe. Step 2: Then, according to the required fire protection level, select inorganic flame retardants such as aluminum hydroxide and magnesium hydroxide, or organic flame retardants such as phosphorus-based and halogen-based ones. Pour the flame retardant and an appropriate amount of water into the liquid preparation tank for mixing to prepare a flame retardant liquid with a concentration of 20% - 30%. Step 3: The stirring shaft drives the stirring rod to rotate to stir the straw. During the stirring process, the flame retardant liquid is slowly added into the mixing cylinder through a water pump, and continuous stirring is carried out for 10 - 30 minutes to enable the straw to evenly adsorb the flame retardant liquid.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the setting of the cleaning mechanism in the present invention, during the stirring process, the protection component can cover the top of the mixing cylinder, reducing the splashing of materials onto the surfaces of parts such as high-pressure nozzles, worm gears, worm wheels, and small bevel gears, avoiding affecting the operation. When the feeding of the stirred and mixed materials is completed, the electric push rod drives the semi-circular plates to move away from each other, and then the electric cylinder drives the annular water tank to descend. The high-pressure nozzle first faces the inner wall of the mixing cylinder, and the high-pressure nozzle can flush the inner wall of the mixing cylinder. When the annular water tank descends, it can drive the scraping ring to descend, and the scraping ring can scrape the materials on the inner wall of the mixing cylinder. Then the driving motor drives one worm gear to rotate, enabling the small bevel gear to drive the large bevel gear to rotate, and the large bevel gear drives the remaining small bevel gears to rotate, so that all worm gears drive the worm wheels to rotate, enabling the rotating shaft to drive the high-pressure nozzle to rotate. When the high-pressure nozzle faces the stirring rod, it can flush the materials adhered to the stirring rod, and through the flushing method, the cleaning effect is better.

The top of the mixing shaft 112 is connected to the output end of the mixing motor.

[0025] Please refer to Figures 1-3 , A forming process for a fireproof and flame-retardant straw floor forming device, the specific steps include: Step 1: Pour the straw from which dust, stones, withered leaves and other sundries have been removed into the crushing box 101. The two crushing rollers 102 rotate to crush the straw. After crushing, it is convenient to mix with the flame retardant liquid. The crushed straw enters the mixing cylinder 2 through the feeding pipe 103; Step 2: Then, according to the required fire resistance level, select inorganic flame retardants such as aluminum hydroxide and magnesium hydroxide, or organic flame retardants such as phosphorus-based and halogen-based ones. Pour the flame retardant and an appropriate amount of water into the liquid preparation tank 111 and mix them to prepare a flame retardant liquid with a concentration of 20% - 30%. Step 3: The stirring shaft 7 drives the stirring rod 8 to rotate and stir the straw. During the stirring process, the flame retardant liquid is slowly added into the mixing cylinder 2 through the water pump 114, and continuous stirring is carried out for 10 - 30 minutes to enable the straw to evenly adsorb the flame retardant liquid. Step 4: Add urea-formaldehyde resin, phenolic resin adhesives, and filler materials such as calcium carbonate and talcum powder into the mixing cylinder 2, and continue stirring for 20 - 60 minutes until all raw materials are fully mixed to form a mixture with a certain viscosity and fluidity. Step 5: Pour the mixed material evenly into the mold, and then form a floor blank through a hot press. After demolding, it enters edge trimming and surface treatment.

[0026] Working principle: During stirring, after the straw is poured into the mixing cylinder 2, the screw rod 502 rotates to lower the Z-shaped plate 503, driving the cylinder cover 6 to descend. Then, the electric push rod 932 drives the connecting plate 933 to contract, causing the two semi-circular plates 934 to combine into one, covering the top of the mixing cylinder 2 to reduce the splashing of materials onto the high-pressure nozzle 914 during stirring, which may cause blockage of the high-pressure nozzle 914. Then, the stirring shaft 7 drives the stirring rod 8 to rotate and stir the straw. The water pump 114 is started, enabling the flame retardant liquid to enter the mixing cylinder 2 through the liquid inlet pipe 115. Finally, the cylinder cover 6 rises, and then adhesives and other filler materials are poured in for re-mixing. After mixing is completed, the material can be discharged through the discharge pipe 4. When it is necessary to clean the inner wall of the mixing cylinder 2, the two semi-circular plates 934 move away from each other. Then, the electric cylinder 911 drives the annular water tank 912 to descend. The connecting pipe 916 is connected to an external water source, and the external water source enters the annular water tank 912 and is sprayed out through the hose 915, water pipe 913, and finally through the high-pressure nozzle 914. The high-pressure nozzle 914 first faces the inner wall of the mixing cylinder 2, and the high-pressure nozzle 914 can wash the inner wall of the mixing cylinder 2. When it is necessary to wash the stirring rod 8, the drive motor 9113 is started, causing the worm 9110 to drive the small bevel gear 9111 to rotate, making the large bevel gear 9112 rotate. The large bevel gear 9112 can drive the other small bevel gears 9111 to rotate, causing the other worms 9110 to rotate, enabling the other worm gears 919 to rotate, and making all the high-pressure nozzles 914 rotate to face the stirring rod 8 (when the rotation directions of the small bevel gears 9111 are different, the threads on the worm 9110 and the worm gear 919 are set in the opposite direction, enabling the high-pressure nozzles 914 to rotate in the same direction) to wash the stirring rod 8. When the annular water tank 912 descends, it drives the scraping ring 922 to descend, and the scraping ring 922 can scrape the inner side wall of the mixing cylinder 2, improving the cleaning effect of the inner side wall of the mixing cylinder 2. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
