Problems solved by technology

[0006] The purpose of the present invention is to overcome the technical problems of the existing huskers that the driving source of the rubber rollers passes through the reduction box, there is a level difference, the linear speed of the rubber rollers cannot be accurately controlled, the quality of husking is difficult to control, and the rubber rollers wear quickly, and it provides a A rice husker and its use method. The rice husker is driven by a direct drive motor, which solves the problem of transmission and positioning, reduces the transmission chain, simplifies the transmission structure, facilitates precise control of the linear speed of the roller, ensures the quality of husking, and reduces the Slow rubber roller wear speed

Embodiment 1

[0045] Such as Figure 1 to Figure 5 As shown, the huller of this embodiment includes a direct-drive motor 8 connected to the rubber roller, and the direct-drive motor 8 has a servo control system. The connecting part is used to connect the rotor of the direct-drive motor 8 and the rubber roller, so that the roller of the rubber roller is concentric with the axis of the drive shaft of the direct-drive motor 8 .

[0046] In this embodiment, the rice huller uses a direct-drive motor to improve the synchronous efficiency of the motor and the rubber roller, ensure the transmission effect, and avoid the transmission and positioning problems caused by the conversion of the drive source by the gearbox. The axis line of the drive shaft of the drive motor is set in parallel, reducing the transmission chain and simplifying the transmission structure, which is convenient for precise control of the linear speed of the roller, ensures the quality of shelling, and slows down the wear speed ...

Embodiment 2

[0048] Such as Figure 1 to Figure 5 As shown, according to the huller described in Embodiment 1, the huller of this embodiment includes two rubber rollers, the two rubber rollers are respectively the first rubber roller 3 and the second rubber roller 4, and the first rubber roller The roller 3 and the second rubber roller 4 are provided with corresponding direct-drive motors 8 respectively, and roller diameter sensors are provided on both rubber roller sides. The change of the diameter of the rubber roller is measured by the roller diameter sensor and transmitted to the controller. The controller then accurately controls the speed of the direct drive motor, and precisely adjusts the linear speed of the two rubber rollers to ensure a constant linear speed difference between the two rollers. Then the shelling quality is guaranteed, and the problem of shelling quality decline caused by drum wear is solved. According to relevant principles, the line speed is directly proportiona...

Embodiment 3

[0050] Such as Figure 1 to Figure 5 As shown, according to the rice huller described in Embodiment 1, the two rubber rollers in this embodiment are respectively the first rubber roller 3 and the second rubber roller 4, and the first rubber roller 3 is connected to the direct drive motor 8 , between the direct-drive motor 8 and the first rubber roller 3, there is a driving connecting sleeve 9, a pulley 13 is provided on the driving connecting sleeve 9, a driven pulley sleeve 16 is arranged on the second rubber roller 4, and A transmission belt 14 is provided, and a roller diameter sensor is arranged on the first rubber roller 3 . In this scheme, the two rubber rollers are respectively driven by the driving source to rotate, and one of the rubber rollers is driven to rotate by the driving source, and the other rubber roller is passively rotated through the belt drive, which reduces the power source and solves the problem that the two rubber rollers are respectively equipped wit...

Abstract

The invention discloses an industrial processing technology. The rice huller comprises a direct-drive motor connected with a rubber roller, the direct-drive motor is provided with a servo control system, a connecting part is arranged between the direct-drive motor and the rubber roller and used for connecting a rotor of the direct-drive motor and the rubber roller, and a roller cylinder of the rubber roller and the axis of a driving shaft of the direct-drive motor are concentric. The rice huller is driven by the direct-drive motor, the problems of transmission and positioning are solved, transmission chains are reduced, the transmission structure is simplified, the linear speed of the roller is conveniently and accurately controlled, the hulling quality is guaranteed, and the abrasion speed of the rubber roller is slowed down.

Description

technical field [0001] The invention relates to an industrial processing technology, in particular to a rice huller and its usage method. Background technique [0002] Husker is a grain processing machine that removes chaff from rice and makes brown rice. It can remove the rice husk, reduce rice grain bursting and skin damage, and keep brown rice intact as much as possible. Its structure is mainly composed of hopper feeding device, machine head device, chaff separation chamber, gear box and frame. [0003] Rubber roller huskers are widely used in huskers. The main working parts are a pair of horizontal rubber rollers bonded or covered with rubber layers on cast iron cylinders. The axes of the two rollers are located in the same horizontal plane or have a slight height difference. Rotate in opposite directions at different speeds, one of the rollers is fixed in position, and the other roller can be moved, so that the rolling distance between the two rollers can be adjusted. ...
