Specific embodiments

[0026] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Referring to Figures 1-6 , a rice mill with a hammer-type cyclone blower includes: a hammer-type cyclone mill 1. It should be noted here that the hammer-type cyclone mill 1 is a high-efficiency, high-speed and widely applicable crushing device, commonly used for crushing grains and miscellaneous grains, which is a common existing crushing device and will not be elaborated here. A fine grinding cylinder 6 is arranged on the side of the hammer-type cyclone mill 1; the fine grinding cylinder 6 includes an upper cylinder 61 and a lower cylinder 62. A hydraulic lifting rod 11 is fixedly installed on the upper side of the upper cylinder 61. The output end of the hydraulic lifting rod 11 passes through to the inside of the upper cylinder 61, and a built-in motor 12 is fixedly installed on the output end of the hydraulic lifting rod 11. A rotating shaft 13 is fixedly installed on the output end of the built-in motor 12. A grinding disc 14 is fixedly installed at the lower end of the rotating shaft 13. The bottom of the upper cylinder 61 is fixedly connected to an upper receiving ring 7. The upper end of the lower cylinder 62 is fixedly connected to a lower receiving ring 8. The upper receiving ring 7 is screwed and installed on the upper side of the lower receiving ring 8. A second ring groove 18 is formed inside the lower receiving ring 8. A grinding groove 19 is arranged inside the second ring groove 18. Leakage holes are evenly arranged on the grinding groove 19. A metal ring frame 20 is fixedly installed outside the grinding groove 19. The metal ring frame 20 is slidably installed inside the second ring groove 18.

[0028] In this method, a reinforcing block 15 is installed outside the joint between the upper side of the grinding disc 14 and the rotating shaft 13.

[0029] Through the above setting, the setting of the reinforcing block 15 improves the structural strength of the fixed connection between the grinding disc 14 and the rotating shaft 13.

[0030] In this method, the lower side surface of the grinding disc 14 is a convex arc surface, the upper side surface of the grinding groove 19 is a concave arc surface matching the lower side surface of the grinding disc 14, and both the grinding disc 14 and the grinding groove 19 are made of white stone.

[0031] Through the above setting, the white stone material has high hardness and wear resistance, which enables it to maintain good cutting performance during grinding, ensuring the grinding fineness of the rice flour, and is not easily worn during use, thus extending the service life and reducing the replacement frequency.

[0032] In this method, a first ring groove 16 is formed on the lower receiving ring 8, and a sealing ring 17 is installed inside the first ring groove 16.

[0033] Through the above setting, when the upper receiving ring 7 and the lower receiving ring 8 are screwed together, the sealing ring 17 can keep the screwed joint in good sealing performance.

[0034] In this method, a feed pipe 2 is connected and installed on the upper side of the hammer type cyclone mill 1, a feeding hopper 3 is fixedly installed on the feed pipe 2, a lateral through pipe 4 is connected and installed on the side of the hammer type cyclone mill 1, a connecting flange 5 is fixedly connected to the end of the lateral through pipe 4, the connecting flange 5 is screwed to the side wall of the upper cylinder 61, and the end of the lateral through pipe 4 is connected and communicated with the inside of the upper cylinder 61.

[0035] Through the above setting, the feeding hopper 3 is used to add rice, and the rice enters the inside of the hammer type cyclone mill 1 through the feed pipe 2 for crushing.

[0036] In this method, a discharge chute 9 is connected and installed on the bottom side of the lower cylinder 62, and a suction pump 21 is installed at the outer port of the discharge chute 9.

[0037] Through the above setting, when the suction pump 21 is started, suction can be generated inside the discharge chute 9, and further suction can be generated at the bottom inside the lower cylinder 62 connected to the discharge chute 9, and further suction can be generated at the bottom of the grinding groove 19, so as to convey the rice flour with qualified grinding fineness downward from the leakage holes on the grinding groove 19.

[0038] In this method, a shock-absorbing base 10 is arranged at the bottom of the lower cylinder 62, and the shock-absorbing base 10 is a rubber cushion plate.

[0039] Through the above setting, the setting of the shock-absorbing base 10 as a rubber cushion plate provides a shock-absorbing effect for the fine grinding cylinder 6.

[0040] The working principle of a rice mill with a hammer-type cyclone fan provided by the present utility model is as follows:

[0041] During use, first start the hydraulic lifting rod 11 to contract, driving the grinding disc 14 to move upward and reset to the inner upper end of the fine grinding cylinder 6. Subsequently, add an appropriate amount of rice into the feeding hopper 3, and start the hammer-type cyclone mill 1. Then the rice enters the hammer-type cyclone mill 1 through the feeding pipe 2 for pulverization. The pulverized primary rice flour is conveyed into the lateral through pipe 4 by the internal fan of the hammer-type cyclone mill 1, and enters the fine grinding cylinder 6 from the lateral through pipe 4. When the hammer-type cyclone mill 1 finishes pulverizing the added rice, the hammer-type cyclone mill 1 stops operating. At this time, the processed rice flour has all been input into the fine grinding cylinder 6 and falls onto the upper side of the grinding groove 19. Subsequently, start the hydraulic lifting rod 11 to drive the grinding disc 14 to the upper side of the grinding groove 19, and simultaneously start the built-in motor 12 and the suction pump 21. The built-in motor 12 drives the grinding disc 14 to rotate and grind on the grinding groove 19 to further finely grind the rice flour and improve the grinding fineness of the rice flour. When the suction pump 21 is started, a suction force can be generated inside the discharge chute 9, and further a suction force is generated at the bottom inside the lower cylinder 62 connected to the discharge chute 9, further generating a suction force at the bottom of the grinding groove 19, thereby conveying the rice flour with qualified grinding fineness downward from the leakage holes on the grinding groove 19 and falling to the bottom of the lower cylinder 62, and finally discharging through the discharge chute 9.

[0042] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present utility model.
