Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, specifically to a conveying device for stone mill flour. Background Technology

[0002] After being ground in a stone mill, the flour needs to be collected from the stone mill and transferred to a storage silo or packaging process via a conveying device. Some conveying devices will assist in separating bran, impurities and flour during the conveying process to improve the purity of the flour. The conveying device can realize the automated process, reduce manual handling and improve production efficiency.

[0003] The existing technology has the following problems:

[0004] Existing equipment cannot perform vibratory screening during the sieving process. Without vibratory screening, flour relies solely on gravity or simple conveying motion to pass through the screen. Fine particles easily accumulate on the screen surface and cannot pass through the screen holes in time, leading to screen blockage. The core function of vibratory screening is to keep flour particles in a loose state on the screen surface through vibration and continuously collide with the screen, thereby accelerating the passage of fine powder through the screen holes. In addition, existing equipment cannot adjust the rotation angle of the guide plate. If the angle of the guide plate is fixed and too large, the material falls too fast from a height and collides violently with the conveying equipment, generating a large amount of dust and scattering. It is impossible to optimize the material flow trajectory by adjusting the angle, and the material may scatter in an irregular manner, increasing the risk of scattering. Utility Model Content

[0005] This invention provides a conveying device for stone-milled flour to solve the problems existing in the background art.

[0022] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0023] like Figure 1 As shown, this utility model provides a conveying device for stone-milled flour, including a base 1, a conveying mechanism 2 fixedly connected to the upper side of the base 1, a sieving box 3 fixedly connected to the upper side of the base 1, a storage box 5 slidably connected through the left side of the sieving box 3, a support plate 4 fixedly connected to the upper side of the base 1, and fixed plates 14 fixedly connected to both the left and right sides of the conveying mechanism 2. A rotating shaft 15 is rotatably connected to the opposite surfaces of the two fixed plates 14. A guide plate 16 is fixedly connected to the outer wall of the rotating shaft 15, and a rotating block 17 is fixedly connected to the left end of the rotating shaft 15. Multiple slots 18 are provided on the outer wall of the rotating block 17, and a fixed block 1 is fixedly connected to the left side of the left fixed plate 14. 9. The base 1 serves as the basic support component, on which the conveying mechanism 2 is fixedly connected for the transmission of flour. The sieving box 3 undertakes the task of sieving flour. The storage box 5 can be inserted or removed from the left side of the sieving box 3 to collect the sieved flour. The support plate 4 serves to support the motor 7. The fixing plates 14 on both sides of the conveying mechanism 2 are used to install the rotating shaft 15. The guide plate 16 is fixed on the rotating shaft 15 and can rotate with the rotating shaft 15. The rotating block 17 is fixedly connected to the left end of the rotating shaft 15. Multiple slots 18 on its outer wall are used to cooperate with the insert 25 to fix the angle of the guide plate 16. The fixing block 19 is fixed on the left side of the left fixing plate 14 to provide an installation base for the angle adjustment mechanism.

[0024] like Figure 2-3As shown, this utility model provides a technical solution: Preferably, a motor 7 is fixedly connected to the front side of the support plate 4, a turntable 8 is fixedly connected to the output shaft of the motor 7, a U-shaped plate 9 is rotatably connected to the eccentric part of the turntable 8, a screening plate 6 is fixedly connected to the other end of the U-shaped plate 9, the outer wall of the screening plate 6 is slidably connected to the screening box 3, connecting blocks 10 are fixedly connected to both the left and right sides of the screening plate 6, and sliding grooves 11 are provided on both the left and right sides of the inner surface of the screening box 3. The outer wall of the connecting block 10 is slidably connected to the sliding groove 11, a guide post 12 is fixedly connected to the upper side of the inner surface of the sliding groove 11, the outer wall of the guide post 12 is slidably connected to the connecting block 10, and a spring 13 is sleeved on the outer wall of the guide post 12. After the motor 7 is started, its output shaft drives the turntable 8 to rotate. As the turntable 8 rotates, the U-shaped plate 9 at the eccentric position of the turntable 8 reciprocates, thereby driving the sieving plate 6 to slide back and forth within the sieving box 3. The connecting blocks 10 on both sides of the sieving plate 6 slide within the sliding groove 11, serving as a guide. The guide post 12 passes through the connecting block 10, and the spring 13 is sleeved on the guide post 12. When the sieving plate 6 moves downward, the spring 13 is compressed. When the sieving plate 6 moves upward, the spring 13 releases its elasticity, assisting the sieving plate 6 in resetting and simultaneously causing the sieving plate 6 to vibrate. This vibration keeps the flour particles on the sieve surface loose, constantly colliding with the sieve mesh, accelerating the passage of fine powder through the sieve holes, preventing sieve clogging, and improving sieving efficiency. It is especially suitable for breaking up flour particles that have clumped due to static electricity or humidity.

[0025] like Figure 4-5As shown, this utility model provides a technical solution: Preferably, a knob 20 is rotatably connected to the lower side of the fixing block 19, a worm 21 is fixedly connected to the upper side of the knob 20, a worm wheel 26 is meshed with the outer wall of the worm 21, a rotating rod 27 is fixedly connected through the left side of the worm wheel 26, both ends of the rotating rod 27 are rotatably connected to the fixing block 19, a gear 28 is fixedly connected to the outer wall of the rotating rod 27, a limit plate 22 is fixedly connected to the lower side of the inner surface of the fixing block 19, a lifting block 23 is slidably connected to the outer wall of the limit plate 22, a rack 24 is fixedly connected to the rear side of the lifting block 23, the outer wall of the gear 28 meshes with the rack 24, a pin 25 is fixedly connected to the upper side of the lifting block 23, the outer wall of the pin 25 is slidably connected to the fixing block 19, and the upper end of the pin 25 is movably connected to the slot 18. Rotating the knob 20 causes the worm 21 to rotate, and the worm 21 meshes with the worm wheel 26. The worm gear 26 rotates, and the worm gear 26 drives the gear 28 to rotate through the rotating rod 27. The gear 28 meshes with the rack 24, which is fixed to the rear side of the lifting block 23. The lifting block 23 slides on the limiting plate 22. Therefore, the rotation of the gear 28 will drive the lifting block 23 to move up and down. The insert 25 on the upper side of the lifting block 23 moves with the lifting block 23. When the insert 25 is pulled out from the slot 18 of the rotating block 17, the rotating block 17 can be rotated, thereby driving the rotating shaft 15 and the guide plate 16 to rotate. After adjusting to a suitable angle, the knob 20 is rotated in the opposite direction to insert the insert 25 into another slot 18 of the rotating block 17, fixing the angle of the guide plate 16. By adjusting the angle of the guide plate 16, the falling speed and trajectory of the material can be controlled. Appropriately reducing the angle can reduce the free fall speed of the material, reduce dust generated by high-speed impact, optimize the material flow trajectory, and reduce the risk of scattering.

[0026] The working principle of this conveying device used for stone mill flour will be explained in detail below.

[0027] like Figure 1-5As shown, after the motor 7 starts, its output shaft drives the turntable 8 to rotate. The U-shaped plate 9 at the eccentric part of the turntable 8 will reciprocate with the rotation of the turntable 8, thereby driving the sieve plate 6 to reciprocate within the sieve box 3. The connecting blocks 10 on both sides of the sieve plate 6 slide within the slide groove 11, serving as a guide. The guide post 12 passes through the connecting block 10, and the spring 13 is sleeved on the guide post 12. When the sieve plate 6 moves downward, the spring 13 is compressed. When the sieve plate 6 moves upward, the spring 13 releases its elastic force, assisting the sieve plate 6 to reset and simultaneously causing the sieve plate 6 to vibrate. This vibration keeps the flour particles on the sieve surface loose, constantly colliding with the sieve mesh, accelerating the passage of fine powder through the sieve holes, preventing sieve clogging, and improving sieve efficiency. It is especially suitable for breaking up flour particles that have clumped due to static electricity or humidity. Turning the knob 20 drives the worm gear 21 to rotate, and the worm gear 21 meshes with the worm wheel 26. This causes the worm gear 26 to rotate, which in turn drives the gear 28 to rotate via the rotating rod 27. The gear 28 meshes with the rack 24, which is fixed to the rear side of the lifting block 23. The lifting block 23 slides on the limiting plate 22. Therefore, the rotation of the gear 28 will cause the lifting block 23 to move up and down. The insert 25 on the upper side of the lifting block 23 moves with the lifting block 23. When the insert 25 is pulled out from the slot 18 of the rotating block 17, the rotating block 17 can be rotated, thereby driving the rotating shaft 15 and the guide plate 16 to rotate. After adjusting to a suitable angle, the knob 20 is rotated in the opposite direction to insert the insert 25 into another slot 18 of the rotating block 17, fixing the angle of the guide plate 16. By adjusting the angle of the guide plate 16, the falling speed and trajectory of the material can be controlled. Appropriately reducing the angle can reduce the free fall speed of the material, reduce dust generated by high-speed impact, optimize the material flow trajectory, and reduce the risk of scattering.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
