[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] Embodiment 1

[0030] Please refer to Figure 1 and Figure 2 As shown, this embodiment provides a rice dandruff removal device, including a base 1, a support frame 2, a vibrator 3 and a dandruff removal box 5. The support frame 2 is installed on the top of the base 1, and the vibrator 3 is located at the bottom of the support frame 2. The dandruff removal box 5 is movably arranged on the support frame 2, the dandruff removal box 5 is in contact with the top of the telescopic rod 42, and a sieve mesh 53 is arranged in the dandruff removal box 5.

[0031] Among them, a telescopic hole 41 is opened on the support frame 2, a telescopic rod 42 is movably connected at the telescopic hole 41, the bottom of the telescopic rod 42 is connected with a vibrating plate 4 below the support frame 2, the vibrator 3 is installed below the vibrating plate 4, and the driving end of the vibrator 3 is in contact with the vibrating plate 4.

[0032] In one embodiment, a vertically arranged vertical rod 43 is provided between the telescopic rod 42 and the vibrating plate 4. The two sides of the vibrating plate 4 close to the damper 8 are inclined upward. The lengths of the vertical rods 43 are different, and the tops of the telescopic rods 42 are on the same horizontal plane and protrude from the support roller 23.

[0033] When using this structure, the vibrator 3 drives the sequential transmission of the vibrating plate 4, the vertical rod 43 and the telescopic rod 42, so that the dandruff removal box 5 realizes the effect of vibrating and sieving. Compared with the sieving technology of air separation, the energy consumption of screening rice impurities by gravity and the vibrator 3 is lower, and the dust generated by air separation is less, which is beneficial to improving the working environment and is more economical and environmentally friendly.

[0034] In one of the embodiments, an installation base 7 is provided on the base 1, and a damper 8 is provided between the installation base 7 and the outer bottom of the support frame 2. Preferably, the damper 8 is a rubber damper 8. By providing the damper 8, when the vibrator 3 produces a needle punching effect, the collision on the equipment is reduced, and the wear resistance and service life of the equipment are increased.

[0035] Embodiment 2

[0036] To solve the problems of screening accuracy and screening efficiency, as Figure 1 and Figure 4 shown, this solution further includes a frequency adjustment device 6. The frequency adjustment device 6 is electrically connected to the vibrator 3. The frequency adjustment device 6 adjusts the rotation speed and vibration frequency of the vibrator 3, thereby adjusting the screening accuracy and screening rate.

[0037] Referring to Figure 5 shown, the frequency adjustment device 6 includes a processor 61, an inverter 62, and a control panel 63. The inverter 62 is connected to the vibrator 3. The inverter 62 and the vibrator 3 are both connected to the processor 61. The control panel 63 is provided on one side of the support frame 2. The control panel 63 is connected to the processor 61. By adjusting the output frequency of the inverter 62, the rotation speed of the motor of the vibrator 3 is changed, thereby adjusting the vibration frequency, and the required vibration frequency is controlled through the control panel 63.

[0038] By providing the frequency adjustment device 6, by adjusting the vibration frequency and amplitude, the screening process can be accurately controlled to ensure that impurities of different sizes and densities are effectively screened out, reducing the loss of rice. Under the condition that the size of the sieve mesh 53 remains unchanged, an appropriate vibration frequency can improve the screening efficiency. In addition, different materials (different types of rice) and screening requirements may require different vibration frequencies. For example, for the screening of fine millet grains, a lower vibration frequency is required to avoid the over-screening of fine particles; while for the screening of larger rice grains, a higher vibration frequency is required to improve the screening efficiency.

[0039] When using this structure, initially, the frequency of the vibrator is increased by the inverter 62 to promote the uniform distribution of rice grains on the sieve surface, avoid material accumulation, and improve the screening effect. After a period of time, the frequency of the vibrator is then reduced to avoid the screening of smaller-sized rice grains. The reduction of the vibration frequency can also save energy, achieving multiple benefits at once.

[0040] Embodiment 3

[0041] Referring to Figure 1 shown, on the outer periphery of the dandruff removal box 5, flanges 51 and clamping grooves 52 that are matched with each other are respectively provided in opposite directions. Adjacent dandruff removal boxes 5 are clamped through the flanges 51 and the clamping grooves 52.

[0042] Through the detachable setting of the dandruff removal box 5, multiple dandruff removal boxes 5 can be spliced to meet the screening work simultaneously, which is more efficient for screening. Moreover, different dandruff removal boxes 5 can meet the screening work of different types of rice, with a wider range of use.

[0043] In one embodiment, a detachable stone storage frame 54 is provided at the bottom of one side of the dandruff removal box 5, and the stone storage frame 54 is arranged at the bottom of the screen 53. The stone storage frame 54 and the dandruff removal box 5 are movably and fixedly connected by existing means, such as a lock or other forms of fixing methods, as long as the situation that the stone storage frame 54 falls out during the vibration process is avoided. This solution will not be elaborated too much in this plan.

[0044] In one embodiment, as Figure 1 shown, the base 1 includes a cross rail 11 and a support 12. Two groups of cross rails 11 are provided. Grooves 13 with an I-shaped cross section are provided on both sides of the cross rail 11. The support 12 is fixedly arranged between the oppositely arranged grooves 13 of the cross rail 11, and a support arm 14 is provided outside the cross rail 11.

[0045] As Figure 3 shown, support legs 21 are provided at the bottom of the support frame 2. Fixed plates 22 are provided at the bottoms of the support legs 21. The fixed plates 22 are fixedly connected to the support arms 14. Support rollers 23 are also provided on the support frame 2 in an array distribution. The telescopic holes 41 are arranged on the support frame 2 between adjacent support rollers 23, and the telescopic rods 42 are arranged between adjacent support rollers 23.

[0046] When the vibrator 3 works, the vibrator 3 is fixed between the support frame 2 and the base 1. Taking the electro-mechanical type as an example, as a common driving method, the vibrator 3 is driven by a motor to generate up and down movement. In this solution, the motor is not involved. The vibrator 3 replaces the combined structure of the two as an existing technology. The rotation of the motor is converted into linear motion through a mechanical structure, so as to realize the up and down movement of the vibrator 3. The vibrator 3 drives the telescopic rod 42 to vibrate up and down about the telescopic hole 41. The telescopic rod 42 is arranged between adjacent support rollers 23. When the telescopic rod 42 moves upward, it drives the dandruff removal box 5 to move upward. When moving downward, it is limited by the support rollers 23, and the screening effect is realized during the vibration process.

[0047] It should be noted that although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, without departing from the purpose of the present invention, without creative design, the structural methods and embodiments similar to this technical solution should all belong to the protection scope of the present invention.
