[0029] In addition, numerous specific details are provided in the following specific examples to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0030] See also Figure 1-Figure 5 In an embodiment of the utility model, a multifunctional pneumatic rice husker includes a frame 1 and a rice husking mechanism installed on the frame 1, and the feeding end of the rice husking mechanism is connected to the hopper 9 through a discharge pipe 13; the discharge pipe 13 is provided with opening and closing sealing parts and a pneumatic pull plate 12 for controlling the discharge amount of the discharge pipe 13 in sequence along the material discharge direction. Specifically, the pneumatic pull plate 12 passes through the strip-shaped through groove formed on the discharge pipe 13 and can slide relative to the discharge pipe 13.

[0031] Specifically, the above-mentioned discharge pipe 13 is a connecting structure between the discharge port of the hopper 9 and the feed port of the rice hulling mechanism. The opening and closing sealing part is arranged at the discharge port of the hopper 9, and the pneumatic pull plate 12 is arranged at the feed port of the rice hulling mechanism. The opening and closing sealing part is used to realize the opening and closing control of the discharge port of the hopper 9, and the pneumatic pull plate 12 is used to realize the area control of the feed port of the rice hulling mechanism, thereby realizing effective control of the discharge amount per unit time, and adjusting the flow rate according to the size and variety of rice, and adjusting different linear speed ratios and air pressures for different lengths and sizes of grains, thereby achieving efficient threshing rate and complete separation effect, meeting high-quality processing requirements.

[0032] Furthermore, the rice hulling mechanism includes a rice hulling box 2 arranged on the frame 1, and the feed port formed on the rice hulling box 2 is connected to the discharge pipe 13; it also includes a fixed rice hulling roller and a movable rice hulling roller, and the fixed rice hulling roller and the movable rice hulling roller are driven to rotate by a driving member installed on the frame 1. Exemplarily, in one embodiment, the driving member includes a transmission wheel 3 and a rotating wheel 4, the transmission wheel 3 is coaxially fixed with the rotating shaft of the fixed rice hulling roller, the rotating wheel 4 is rotatably connected to the movable roller 6, and the transmission wheel 3 and the rotating wheel 4 are connected by a belt.

[0033] In this embodiment, it should be noted that the transmission wheel 3 is driven to rotate by a motor installed on the frame 1. When the motor is working, it drives the transmission wheel 3 to rotate, and the transmission wheel 3 drives the fixed hulling roller to rotate. At the same time, the belt drives the rotating wheel 4 to rotate synchronously and in the same direction. The rotating wheel 4 drives the movable hulling roller to rotate through the movable roller 6, and the rotation direction is opposite to the rotation direction of the fixed hulling roller. The rice passing through the fixed hulling roller and the movable hulling roller is husked, thereby meeting the processing requirements.

[0034] Among them, the movable roller component 6 includes a driven gear fixed coaxially with the movable hulling roller and a driving gear fixed coaxially with the rotating wheel 4. The driving gear is engaged with the driven gear and also includes a shell mounted on the outside of the driven gear and the driving gear. The shell can rotate relative to the rotating shaft of the rotating wheel 4, so that when the movable roller component 6 rotates as a whole, it can drive the movable hulling roller to move relative to the rice hulling box 2, thereby changing the distance between the fixed hulling roller and the movable hulling roller, so as to realize the hulling processing of rice of different specifications and varieties.

[0035] Furthermore, a shaft sleeve 5 coaxially arranged with the transmission wheel 3 is sleeved on the rotating shaft of the fixed hulling roller and fixedly connected to the frame 1. An adjusting cylinder 7 is hinged on the shaft sleeve 5. The movable end of the adjusting cylinder 7 is hinged to the movable roller member 6. Combined with the specific structure of the above-mentioned movable roller member 6, the movable end of the adjusting cylinder 7 is hinged to the shell. When the adjusting cylinder 7 moves in an extension and contraction manner, it can drive the shell to rotate along the rotating shaft of the rotating wheel 4, thereby adjusting the position of the movable hulling roller in the hulling box 2, realizing the distance adjustment between the fixed hulling roller and the movable hulling roller, and convenient control.

When the control cylinder 8 is extended and retracted, the sealing plate 14 is driven to move relative to the discharge pipe 13, thereby realizing the blocking or conduction of the discharge pipe 13.

[0037] Preferably, an observation window 10 is provided on one side wall of the hopper 9, through which the remaining rice in the hopper 9 can be conveniently observed, which can effectively prevent overflow caused by excessive rice in the hopper 9, or can turn off the rice huller immediately after the rice in the hopper 9 is discharged.

[0038] In one embodiment of the present invention, the multifunctional pneumatic rice huller also includes a controller 11 installed on the side end of the frame 1, and the controller 11 is used to control the movement of the motor, control the cylinder 8 and adjust the cylinder 7. Specifically, the controller 11 includes a power start button, a power off button, an air pressure button, an air pressure gauge and an adjustment button.

[0039] The air pressure buttons are used to control the air cylinder 8, and there are three of them. The three air pressure buttons represent the air pressure values ​​of 1 pound, 1.2 pounds and 1.5 pounds respectively.

[0040] The adjusting buttons are used to adjust the cylinder 7, and three adjusting buttons are provided. The three adjusting buttons are used to control the movable roller 6 to rotate to different placement angles.

[0041] Of course, the specific number of air pressure buttons and adjustment buttons can be selected according to actual needs, and this embodiment does not make any specific restrictions on this. The above-mentioned number of air pressure buttons and adjustment buttons is a preferred embodiment.
