[0023] Because the existing mixer is often back manual feeding mixing processing, or less front manual feeding operation, but the front manual feeding operation is easy to cause the rack to overturn, the plastic rice raw material is wasted and spilled out, the tightness of the cover fixed cooperation of the inlet structure is insufficient, and the design architecture of the equipment inlet is laborious for manual operation, so that the finished product of the mixer is contaminated with dust, the quality is not good, and the material is wasted.

[0024] The front side of the bottom of the stand 3 is provided with a mixing tank 1 which can be turned over through a rotating shaft, the dust cover 2 is directly below the inlet door 6, the mixing tank 1 drives the dust cover 2 to turn over upward through the rotating shaft, the vertical surface of the dust cover 2 is turned over to realize the action process of front feeding by fitting the front end frame of the stand 3 close to the rear side of the inlet door 6, the slot at the front end of the mixing tank 1 is fixed together with the frame opening of the dust cover 2 base through bolts, and the front end of the stand 3 is gap fitted with the rear of the inlet door 6.

[0025] It should be noted that the front feeding action process of the mixer makes the mixer stable against spilling raw materials, and the tightness of the wrapped material after discharging is strong, the assembly tightness of the mixing tank 1 and the dust cover 2 cooperates with the linkage of the stand 3 cylinder lifting the inlet door 6, which ensures the smoothness and convenience of the front feeding action of the mixer.

[0026] The left and right sides of the front end frame of the stand 3 are tightly attached with outer dust strips 4, the left and right sides of the front end inner frame of the stand 3 are tightly attached with inner dust strips 13, the bottom of the inlet door 6 is transversely attached with an inlet door sealing strip 11, the left and right sides of the inlet door sealing strip 11 are fixedly provided with sealing strips 12, and the outer dust strips 4 and the inner dust strips 13 are tightly attached together.

[0027] It should be noted that the front feeding action process of the mixer makes the outer dust strips 4 and the inner dust strips 13 drive the stand 3 to fit the mixing tank 1, and the top opening of the mixing tank 1 is fitted with the inlet door through the cooperation of the inlet door sealing strip 11 and the sealing strip 12, which improves the tightness and dust prevention of the inlet of the whole mixer.

[0028] The horizontal pole 9 is arranged above the inlet door 6, the left and right lower corners of the horizontal pole 9 are respectively inserted with connecting rods 10, the inlet door cylinder 7 is vertically inserted and embedded on the top of the middle section of the horizontal pole 9, the inlet door cylinder support 8 is fixedly arranged on the top of the inlet door cylinder 7, the inlet door cylinder support 8 is inserted into the top of the stand 3, and the connecting rods 10 are locked together with the front end face of the inlet door 6 through lock ear plates.

[0029] It should be noted that the inlet door cylinder 7 pushes the horizontal pole 9 and the connecting rods 10 to move downward to the inlet door 6, so as to achieve the operation effect that the cylinder lifts the inlet door 6 and the front dust cover is strictly matched with the front feeding.

[0030] The left and right sides of the front end of the stand 3 are respectively provided with an inlet door guide strip 5, and the inlet door 6 is matched with the inlet door guide strip 5.

[0031] It should be noted that, through the process of pushing the cross arm 9 and the connecting rod 10 to move the inlet door 6 downward by the inlet door cylinder 7, the stable effect of the cylinder lifting the inlet door 6 through the inlet door guide strip 5 to adapt to the up-down displacement clamping track is achieved.
