[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. When the present invention is used for the conveying operation of flour raw materials, it can simultaneously realize synchronous vibration dust shaking and negative pressure dust suction in the axial direction and the longitudinal direction of the conveying shaft during the conveying process of the flour raw materials. Through the realization of the above technical effects, the dust removal efficiency and dust removal cleanliness of the equipment are effectively improved.

[0016] 2. In the present invention, during the flour raw material conveying operation, the conveying motor outputs a rotational speed at a set power. When the conveying motor is operating, the spiral conveying blade rotates at a set speed, causing the flour raw materials entering the inner side of the dust-permeable cylinder to be conveyed upward at a set speed. During the flour raw material conveying operation, the conveying motor outputs a rotational speed at a set power. After the conveying motor outputs the rotational speed, the reciprocating shaft is driven. After the reciprocating shaft is driven, the dust-shaking tooth plate is then driven through the semi-circular gear. When the dust-shaking tooth plate is driven, due to the T-shaped guide rod, the return spring, and the semi-circular tooth structure of the semi-circular gear, the dust-shaking seat can reciprocate within a set stroke. After the dust-shaking seat reciprocates within the set stroke, the dust-shaking operation of the flour raw materials can then be carried out. During the conveying operation, while the spiral conveying blade is rotating, due to the setting of the dust-shaking seat, the spiral conveying blade can also perform vertical reciprocating vibrations with a set frequency and a set stroke. After the spiral conveying blade vibrates, the dust in the flour raw materials leaks through the dust leakage holes into the dust accumulation cylinder. And when the flour raw materials are being conveyed, the negative pressure vacuum cleaner continuously operates, then carrying out the negative pressure dust suction operation during the flour raw material conveying process. When the dust-shaking seat reciprocates within the set stroke, the distance between the eccentric seat and the driven rotating ring changes reciprocally. After the distance between the eccentric seat and the driven rotating ring changes reciprocally, through the connection setting of the connecting rod, the position of the eccentric seat on the rotating frame is then reciprocally changed. Through the reciprocal change of the position of the eccentric seat on the rotating frame, the swinging amplitude of the conveying shaft and the dust-permeable cylinder is then reciprocally changed. Through the longitudinal swinging of the conveying shaft and the dust-permeable cylinder, the longitudinal dust-shaking of the flour raw materials conveyed on the spiral conveying blade is thus achieved.

[0042] The reciprocating transmission module includes a driven rotating ring 19 rotatably connected to the dust removing frame 1, and a connecting rod 20 is hinged between the driven rotating ring 19 and the eccentric seat 5;

[0043] When the dust shaking seat 2 reciprocates within the set stroke, the distance between the eccentric seat 5 and the driven rotating ring 19 changes reciprocally. After the distance between the eccentric seat 5 and the driven rotating ring 19 changes reciprocally, through the connection setting of the connecting rod 20, the position of the eccentric seat 5 on the rotating frame 3 is then changed reciprocally. Through the reciprocal change of the position of the eccentric seat 5 on the rotating frame 3, the swinging amplitude of the conveying shaft 6 and the dust permeating rotating cylinder 7 is thus changed reciprocally;

[0044] Through the swinging of the conveying shaft 6 and the dust permeating rotating cylinder 7 in the longitudinal direction, the longitudinal dust shaking of the flour raw materials conveyed on the spiral conveying blade 8 is thus realized;

[0050] A spiral conveying blade 8 is fixedly installed on the conveying shaft 6 at a position corresponding to the inner side of the dust permeating rotating cylinder 7. Vertical dust leakage holes 9 are evenly distributed on the spiral conveying blade 8, and the axis of the dust leakage hole 9 is perpendicular to the horizontal plane;

[0051] The aperture of the dust leakage hole 9 can be customized according to the actual filtration requirements of the flour raw materials;

[0052] An outer cylinder 10 is installed on the dust permeating rotating cylinder 7, and a feeding / discharging component and a dust suction component that cooperate with the dust permeating rotating cylinder 7 are respectively installed on the outer cylinder 10.

[0053] The feeding / discharging component includes a feeding box 26 installed on the upper part of the outer cylinder 10 and a feeding pipe 27 fixed to the dust removal frame 1. A first corrugated connecting pipe is communicated between the feeding pipe 27 and the feeding box 26;

[0054] A feed box 28 is installed at the lower part of the outer cylinder 10. A feed pipe 29 is installed on the dust removal frame 1. A second corrugated connecting pipe is connected between the feed pipe 29 and the feed box 28.

[0055] A set of material-passing openings 30 are provided on the dust-passing rotary cylinder 7 corresponding to the inner side positions of the blanking box 26 and the inner side position of the feed box 28.

[0056] During the conveying operation, the flour raw material to be conveyed enters the inner side of the dust-passing rotary cylinder 7 through the feed pipe 29, the feed box 28 and the material-passing openings 30.

[0057] The flour raw material entering the inner side of the dust-passing rotary cylinder 7 is finally discharged through the blanking box 26 and the blanking pipe 27 under the lifting action of the spiral conveying blade 8.

[0058] When the conveying motor 11 works, the spiral conveying blade 8 rotates at a set speed and makes the flour raw material entering the inner side of the dust-passing rotary cylinder 7 be conveyed upward at a set speed.

[0059] The dust suction component includes a negative pressure dust collector 31 fixed on the dust removal frame 1 and a dust accumulation cylinder 32 fixed at the bottom end of the outer cylinder 10. A dust discharge valve is provided at the bottom end of the dust accumulation cylinder 32. A plurality of groups of dust-passing holes 33 distributed in a circumferential array are provided on the dust-passing rotary cylinder 7. The axis of the dust-passing holes 33 is perpendicular to the axis of the dust leakage holes 9. The aperture of the dust-passing holes 33 is the same as the aperture of the dust leakage holes 9. A negative pressure suction hood 34 is connected to the outer cylinder 10. A third corrugated connecting pipe is connected between the negative pressure dust collector 31 and the negative pressure suction hood 34.

[0060] During the conveying operation, when the spiral conveying blade 8 rotates, it can also perform up-and-down reciprocating jitter with a set frequency and a set stroke. After the spiral conveying blade 8 jitters, the dust in the flour raw material leaks into the dust accumulation cylinder 32 through the dust leakage holes 9.

[0061] And when the flour raw material is conveyed, the negative pressure dust collector 31 continuously works, and then the negative pressure dust suction operation is carried out during the conveying process of the flour raw material.

[0062] Working principle and usage process of the present invention: During the conveying operation, the flour raw material to be conveyed enters the inner side of the dust-permeating rotary cylinder 7 through the feeding pipe 29, the feeding box 28, and the material-penetrating port 30. The flour raw material entering the inner side of the dust-permeating rotary cylinder 7 is finally discharged through the blanking box 26 and the blanking pipe 27 under the lifting action of the spiral conveying blade 8. When the conveying motor 11 works, the spiral conveying blade 8 rotates at a set speed, and makes the flour raw material entering the inner side of the dust-permeating rotary cylinder 7 be conveyed upward at a set speed. During the flour raw material conveying operation, the conveying motor 11 outputs a rotational speed at a set power. After the conveying motor 11 outputs the rotational speed, the reciprocating shaft 13 is driven. After the reciprocating shaft 13 is driven, it then drives the dust-shaking tooth plate 15 to move through the half-face gear 14. When the dust-shaking tooth plate 15 is driven, through the T-shaped guide rod 16, the return spring 17, and the half-face tooth structure of the half-face gear 14, the dust-shaking seat 2 can reciprocate within a set stroke. After the dust-shaking seat 2 reciprocates within the set stroke, the dust-shaking operation of the flour raw material can be carried out. During the conveying operation, when the spiral conveying blade 8 rotates, due to the setting of the dust-shaking seat 2, the spiral conveying blade 8 can also reciprocate up and down with a set frequency and a set stroke. After the spiral conveying blade 8 shakes, the dust in the flour raw material leaks into the dust accumulation cylinder 32 through the dust leakage holes 9. And when the flour raw material is conveyed, the negative pressure vacuum cleaner 31 continuously works, and then the negative pressure dust suction operation during the flour raw material conveying process is carried out. When the dust-shaking seat 2 reciprocates within the set stroke, the distance between the eccentric seat 5 and the driven rotating ring 19 changes reciprocally. After the distance between the eccentric seat 5 and the driven rotating ring 19 changes reciprocally, through the connection setting of the connecting rod 20, the position of the eccentric seat 5 on the rotating frame 3 is then changed reciprocally. By reciprocally changing the position of the eccentric seat 5 on the rotating frame 3, the swinging amplitude of the conveying shaft 6 and the dust-permeating rotary cylinder 7 is reciprocally changed. Through the longitudinal swinging of the conveying shaft 6 and the dust-permeating rotary cylinder 7, the longitudinal dust-shaking of the flour raw material conveyed on the spiral conveying blade 8 is realized.
