Through the above settings, the utility model can complete the function of large-scale feeding through the set feed port 100, batch crush the grains through the crushing component 300, and then the preliminarily crushed grains will be input into the grinding mechanism 500 for fine grinding to complete the assembly line operation, and the processed grains will be temporarily stored in the basic shell 400 and then freely accessed through the discharge structure 600.
[0028] In one embodiment, Figure 3As shown, the crushing component 300 includes a detachable screen 301, a rotating shaft 302, a disc 303 and a crushing hammer 304. The detachable screen 301 is arranged in the protective shell 200 and connected to the lower end of the feed port 100. The rotating shaft 302 is arranged inside the detachable screen 301. Four discs 303 are fixedly arranged in an array on the rotating shaft 302. Six crushing hammers 304 are rotatably arranged in an array between every two discs 303. Through the above arrangement, when the rotating shaft 302 rotates, it drives the fixed discs 303 to rotate together, and at the same time, the crushing hammers 304 arranged on the discs 303 start to swing, thereby crushing the food material entering the crushing component 300.
[0029] In one embodiment, Figure 2 As shown, the grinding mechanism 500 includes an upper grinding disc 501, a lower grinding disc 502, a feed hole 503 and a drive roller 504. The lower grinding disc 502 is fixedly arranged at the bottom of the basic shell 400, the upper grinding disc 501 is rotatably arranged above the lower grinding disc 502, the drive roller 504 is arranged at the center of the upper grinding disc 501 and the lower grinding disc 502, and the feed hole 503 is arranged on the upper grinding disc 501. Through the above arrangement, when the feed hole 503 is rotated to a position opposite to the opening position at the lower end of the protective shell 200, the initially crushed grain will pass through the feed hole 503 and enter between the upper grinding disc 501 and the lower grinding disc 502 for grinding, and the ground grain will leak out from the side seam of the upper grinding disc 501 and the lower grinding disc 502 into the basic shell 400.
[0030] In one embodiment, Figure 4 As shown, the discharge structure 600 includes a discharge port 601, a baffle 602 and a fixed support 603. The discharge port 601 is arranged on the outside of the basic shell 400, and the fixed support 603 is fixed on the discharge port 601. The baffle 602 is rotatably connected to the fixed support 603. Through the above arrangement, the stored processed grain can be leaked out by rotating the baffle 602 when necessary, and the leakage of the grain can be blocked by lowering the baffle 602 when not needed.
[0031] In one embodiment, Figure 1-Figure 2As shown, the driving assembly 700 includes a first motor housing 701, a second motor housing 702, a first motor 703 and a second motor 704. The first motor housing 701 is arranged on the outside of the protective housing 200, the first motor 703 is arranged in the first motor housing 701, the output end of the first motor 703 is connected to the input end of the rotating shaft 302, the second motor housing 702 is arranged at the lower end of the base housing 400, the second motor 704 is arranged in the second motor housing 702, and the output end of the second motor 704 is connected to the input end of the transmission roller 504. Through the above arrangement, the first motor housing 701 and the second motor housing 702 protect the first motor 703 and the second motor 704 from being damaged by external factors. The first motor 703 drives the crushing member 300 to operate by controlling the rotating shaft 302, and the second motor 704 drives the grinding mechanism 500 to operate by controlling the transmission roller 504 to rotate.
[0032] In one embodiment, Figure 1 As shown, a removable baffle 201 is provided on one side of the protective shell 200. Through the above arrangement, it is convenient to clean the residual grain in the protective shell 200 and replace the removable screen 301.
[0033] In one embodiment, Figure 2 As shown, the upper and lower ends of the feed hole 503 are flush with the upper and lower ends of the upper grinding disc 501. Through the above arrangement, the preliminarily crushed grains will leak into the gap between the upper grinding disc 501 and the lower grinding disc 502 for fine grinding.
[0034] Example 2
[0035] In one embodiment, Figure 3 As shown, an observation window 900 is provided at the upper end of the protective shell. Through the above arrangement, the working condition of the crushing component 300 can be observed to facilitate timely handling of blockage problems.
[0036] The above embodiment discloses a grain crushing and grinding device. When the device is working, a large amount of grain can be continuously input into the feed port 100. The input grain will be crushed in batches by the crushing hammer 304 in the crushing component 300 at the lower end of the feed port 100. When the grain particle size reaches less than or equal to one millimeter, it will be input into the grinding mechanism 500 through the detachable screen 301. In the grinding mechanism 500, it will enter the gap between the upper grinding disc 501 and the lower grinding disc 502 through the feed hole 503 for grinding. After the fine grinding, the grain will be sent to the basic shell 400 for temporary storage, and finally the processed grain will be extracted by rotating the baffle 602.
[0037] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
