Description

Technical Field

[0001] The invention relates to the technical field of flour conveying, in particular to a conveying device for high-fiber flour. Background Art

[0002] There are many kinds of food made from flour. High-fiber flour is made from high-quality wheat. Special technology is used to retain the original nutrients of wheat while adding dietary fiber to make the nutrition balanced. After high-quality wheat is processed into high-fiber flour, a conveying device is needed to transport the high-fiber flour from one location to another.

[0003] When conveying high-fiber flour, a special screw conveyor is often used to convey the high-fiber flour. When the screw conveyor conveys the high-fiber flour, the flour needs to be first fed into the feed hopper at the front end of the screw conveyor, and the flour is discharged through the feed hopper to complete the conveying of the high-fiber flour. During the conveying process, when the high-fiber flour inside the feed hopper is discharged, the flour in the middle position is generally discharged first, and the high-fiber flour at the edge is adsorbed on the edge of the feed hopper due to the intermolecular force, resulting in slow discharge of the high-fiber flour at the edge. When the flour in the middle of the feed hopper is about to be discharged, the high-fiber flour at the edge will slowly slide to the middle, resulting in a smaller amount of high-fiber flour falling into the screw conveyor, thereby reducing the conveying efficiency. In order to facilitate the high-fiber flour at the edge to enter the center position, manual intervention is generally used to move the high-fiber flour at the edge to the center position. However, the above method is time-consuming and labor-intensive, and the flour conveying effect is poor. Summary of the invention

[0016] The present invention has the following beneficial effects:

[0017] 1. In the conveying device for high-fiber flour, a flour stirring mechanism is provided, and a driving motor drives a transmission gear to rotate, and the transmission gear drives a rack to rotate, and the rack drives a convex ring to rotate in a rotating groove, and the convex ring drives a first ring to rotate in a conveying pipe, and the conveying pipe drives a stirring rod to rotate along the inner wall direction of a hopper, so that the stirring rod can rotate and stir the flour inside the hopper. When the stirring rod rotates, the speed at which the flour falls to the middle of the hopper can be accelerated, and the amount of flour falling into the conveying pipe can be increased, so as to increase the amount of flour conveyed by the screw conveyor and improve the conveying efficiency;

[0018] In order to reduce the accumulation of flour on the first ring, the upper surface of the first ring is set to a downwardly inclined conical section. The design of the conical section facilitates the discharge of flour through the first ring, which can reduce the excessive accumulation of flour on the upper surface of the first ring, thereby facilitating the sufficient discharge of flour and reducing waste.

[0019] 2. In the conveying device for high-fiber flour, the transmission assembly and the knocking assembly are arranged. When the first ring rotates to drive the stirring rod to stir the flour, the slider can be driven to slide in the special-shaped ring groove, so that the slider can drive the transmission assembly to reciprocate. The reciprocating motion of the transmission assembly drives the knocking assembly to reciprocate, so that the knocking assembly knocks the inner wall of the hopper back and forth. When knocking the inner wall of the hopper, the inside of the hopper will vibrate. The vibration is used to accelerate the collapse speed of the flour on the top of the hopper, so that more flour on the top of the hopper falls to the bottom of the hopper, which is beneficial to improve the conveying efficiency of the flour.

[0020] 3. In the conveying device for high-fiber flour, when the knocking component knocks the inside of the hopper, the slider can drive the air outlet pipe to move up and down, so that the air outlet pipe can drive the annular air bag to exhaust and inflate. When the knocking component is knocking with accumulated force, the annular air bag can be squeezed to discharge the gas inside the annular air bag through the air outlet pipe. The gas enters the through groove through the movable groove and the straight groove, and is blown out from the port of the through groove. The wind force is used to effectively prevent flour from entering the through groove, thereby reducing the situation of flour entering the through groove, which is beneficial to increase the knocking effect of the knocking component, making the vibration generated by the knocking component when knocking more obvious, and further improving the flour feeding efficiency.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0039] The hopper 3 and the feed pipe 4 are provided with a flour stirring mechanism 7 for stirring the flour, the flour stirring mechanism 7 comprises a stirring rod 71 rotatably arranged in the hopper 3, a first circular ring 72 is rotatably arranged inside the feed pipe 4, the stirring rod 71 is fixed on the surface of the first circular ring 72, a rotating groove 73 is provided inside the feed pipe 4, a convex ring 74 is fixed on the surface of the first circular ring 72, a rack 75 is fixed on the convex ring 74, a driving motor 76 is installed outside the feed pipe 4, a transmission gear 77 is connected to the output end of the driving motor 76, the transmission gear 77 is rotatably arranged in the rotating groove 73, and the transmission gear 77 is meshed with the rack 75;

[0040] In the technical solution, when conveying flour, firstly, the fixed frame 1 is driven to move by the universal wheel 2, the device is moved to the required position and fixed, and then the flour is fed into the hopper 3, and enters the screw feeder 5 through the feed pipe 4, and the flour is conveyed by the screw feeder 5, and the conveyed flour is discharged through the discharge port 6;

[0041] When the flour is fed into the hopper 3, the flour is stirred by the flour stirring mechanism 7, so that the flour inside the hopper 3 can be transported faster through the feeding pipe 4 into the screw feeder 5. Specifically, the driving motor 76 drives the transmission gear 77 to rotate, the transmission gear 77 drives the rack 75 to rotate, the rack 75 drives the convex ring 74 to rotate in the rotating groove 73, the convex ring 74 drives the first ring 72 to rotate in the feeding pipe 4, and the feeding pipe 4 drives the stirring rod 71 to rotate along the inner wall direction of the hopper 3, so that the stirring rod 71 rotates and stirs the flour inside the hopper 3. When the stirring rod 71 rotates, the speed at which the flour falls to the middle of the hopper 3 can be accelerated, and the amount of flour falling into the feeding pipe 4 can be increased, which is conducive to increasing the amount of flour transported by the screw feeder 5 and improving the transportation efficiency.

[0042] The upper surface of the first circular ring 72 is provided with a downwardly inclined conical section 721, a stabilizing frame 8 is welded on the fixing frame 1, a pulley 9 is installed at the bottom of the stabilizing frame 8, a supporting frame 10 is welded on the top of the stabilizing frame 8, a positioning ring 11 is fixed on the supporting frame 10, and the positioning ring 11 is sleeved on the screw conveyor 5;

[0043] In the present technical solution, by setting the upper surface of the first circular ring 72 as a downwardly inclined conical section 721, the design of the conical section 721 can facilitate the discharge of flour through the first circular ring 72, which can reduce the excessive accumulation of flour on the upper surface of the first circular ring 72, thereby facilitating the sufficient discharge of flour and reducing waste; by setting the stabilizing frame 8, the supporting frame 10 and the positioning ring 11, the screw conveyor 5 can be supported, the stability of the screw conveyor 5 is increased, and the safety of the structure is improved.

[0044] In the second embodiment, since the stirring rod 71 only stirs the bottom of the hopper 3, and the top of the hopper 3 is not stirred, when the flour at the bottom of the hopper 3 is discharged, the flour at the top will fall downward in a collapsed manner. However, due to the intermolecular force between the flours, the flour is not easy to collapse, or cannot collapse quickly, so that the flour at the top of the hopper 3 cannot fall to the bottom of the hopper 3 in time, thereby affecting the feeding rate of the flour. To solve this problem, this embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figure 1-Figure 15, the stirring rod 71 is elastically connected with a plurality of knocking components 12, and the knocking components 12 cause the hopper 3 to vibrate by knocking the inner wall of the hopper 3, and a second ring 13 is fixed inside the feeding pipe 4, and the second ring 13 is arranged below the first ring 72, and a special-shaped ring groove 14 is provided on the second ring 13, and a slider 15 for sliding in the special-shaped ring groove 14 is provided in the first ring 72, and a transmission component 16 is provided between the slider 15 and the stirring rod 71, and the transmission component 16 is connected to the knocking component 12;

[0045] The transmission assembly 16 includes a straight groove 161 provided inside the stirring rod 71, a straight rod 162 is elastically connected inside the straight groove 161, a movable rod 163 is rotatably connected between the end of the straight rod 162 and the end of the slider 15, a movable groove 164 for the movable rod 163 and the slider 15 to move is provided inside the first ring 72, and a resisting rod 165 connected to the knocking assembly 12 is fixed on the straight rod 162;

[0046] The knocking assembly 12 includes a through slot 121 provided on the stirring rod 71, a knocking column 122 is elastically connected in the through slot 121, a limit frame 123 is fixed to the outer surface of the knocking column 122, a triangular abutment platform 124 is arranged in the limit frame 123, the abutment rod 165 is inserted into the limit frame 123, and a rotating plate 125 is elastically arranged on the triangular abutment platform 124;

[0047] A spring slot 166 is provided inside the stirring rod 71, and a first spring 167 is provided in the spring slot 166. A pressing plate 168 is fixed to the end of the straight rod 162, and the pressing plate 168 is provided in the spring slot 166. A second spring 126 is provided in the through slot 121, and both ends of the second spring 126 are fixed to the knocking column 122 and the bottom wall of the through slot 121.

[0048] The special-shaped annular groove 14 comprises a horizontal bottom portion 141, an inclined rising portion 142, a horizontal top portion 143 and a vertical descending portion 144 which are connected in sequence;

[0049] In the technical solution, when the first ring 72 rotates to drive the stirring rod 71 to stir the flour, the slider 15 first slides along the horizontal bottom 141 of the special-shaped annular groove 14 toward the horizontal top 143, and the slider 15 moves upward along the movable groove 164 through the inclined rising portion 142. The upward movement of the slider 15 drives the movable rod 163 to move in the movable groove 164, so that the movable rod 163 pushes the straight rod 162 to move upward along the straight groove 161. When the straight rod 162 moves upward, the first spring 167 is squeezed by the pressure plate 168, so that the first spring 167 accumulates force, and at the same time drives the resistance rod 165 to move upward (such as Fig.15As shown), when the resisting rod 165 moves upward, the rotating plate 125 is configured to be able to Fig.10 The state shown) is turned downward, and cannot be turned (as shown) Fig.10 As shown in the state), the abutment rod 165 rotates upward, so that the abutment rod 165 abuts the rotating plate 125 and slides along the rotating plate 125 and the lower surface of the triangular abutment platform 124, causing the triangular abutment platform 124 to move rightward (as shown in the state). Fig.10 As shown in the figure, the triangular abutment platform 124 moves to the right, driving the knocking column 122 to move to the right, and causing the second spring 126 to store force. When the abutment rod 165 moves to the top along the triangular abutment platform 124, the second spring 126 releases force instantly, causing the abutment rod 165 to slide along the upper surface of the triangular abutment platform 124. The second spring 126 pushes the knocking column 122 to move to the left, causing the knocking column 122 to knock on the inside of the hopper 3.

[0050] Then the slider 15 continues to slide in the special-shaped annular groove 14. When the slider 15 slides from the horizontal top 143 to the horizontal bottom 141, the vertical descending portion 144 is provided to release the force through the first spring 167, so that the pressure plate 168 is reset, and the reset of the pressure plate 168 drives the straight rod 162 to reset, and the reset of the straight rod 162 drives the abutment rod 165 to move downward (such as Fig.10 As shown in the figure, when the abutment rod 165 moves downward, it drives the rotating plate 125 to rotate downward until the abutment rod 165 is reset. At this time, since the rotating plate 125 is elastically connected to the triangular abutment platform 124 by a torsion spring, the torsion spring is arranged at the connection between the rotating plate 125 and the triangular abutment platform 124, so that the rotating plate 125 can rotate upward and reset after rotating downward and losing the abutment rod 165, and reset to the position shown in the figure. Fig.10 When the straight rod 162 is in the middle state, the movable rod 163 drives the slider 15 to move downward in the movable groove 164 when the straight rod 162 is reset, so that the slider 15 vertically drops along the vertical descending portion 144 to the horizontal bottom 141. At this time, the slider 15 also impacts the horizontal bottom 141 of the special-shaped annular groove 14. The impact force generated when the slider 15 vertically drops along the vertical descending portion 144 to the horizontal bottom 141 further generates vibration, which is conducive to improving the feeding speed of flour;

[0051] To sum up, in the present technical solution, while the first circular ring 72 drives the stirring rod 71 to stir the flour, the first circular ring 72 drives the slider 15 to slide along the special-shaped ring groove 14, so that the knocking column 122 can reciprocate to knock on the inside of the hopper 3, and generate vibration at the same time. The vibration is used to accelerate the collapse speed of the flour on the top of the hopper 3, so that more flour on the top of the hopper 3 falls to the bottom of the hopper 3, which is beneficial to improve the flour conveying efficiency.

[0052] In the third embodiment, during the reciprocating motion of the knocking column 122 to knock the inner wall of the hopper 3, when the knocking column 122 moves into the through groove 121, the flour will enter the through groove 121, and then when the knocking column 122 knocks the inner wall of the hopper 3, due to the presence of flour in the through groove 121, the flour will hinder the knocking column 122 from knocking the hopper 3, affecting the knocking efficiency, thereby reducing the vibration effect. In view of this problem, this embodiment is an improvement made on the basis of the second embodiment. For details, please refer to Figure 1-Figure 15 , an annular receiving groove 17 is provided in the second circular ring 13, an annular airbag 18 is provided inside the annular receiving groove 17, an air inlet 19 is provided on the annular airbag 18, a first one-way valve 20 is installed on the air inlet 19, an air outlet pipe 21 is connected to the annular airbag 18, an end of the air outlet pipe 21 is inserted in the slider 15, a second one-way valve 22 is installed on the air outlet pipe 21, an annular groove 23 for sliding the air outlet pipe 21 is provided between the special-shaped annular groove 14 and the annular receiving groove 17, the air outlet pipe 21 is connected to the movable groove 164, the straight groove 161 and the through groove 121, and a vent 24 connected to the annular receiving groove 17 is provided on the feed pipe 4;

[0053] In the technical solution, the annular airbag 18 is configured as a corrugated airbag, which is elastic and can be exhausted when squeezed. After the pressure disappears, it returns to its original state. Through the first one-way valve 20, the gas can only enter the annular airbag 18 from the air inlet 19 to inflate the annular airbag 18. Through the second one-way valve 22, the gas can only enter the air outlet pipe 21 from the annular airbag 18 to deflate the annular airbag 18.

[0054] When the slider 15 slides in the special-shaped annular groove 14, since the air outlet pipe 21 is inserted into the slider 15 and fixedly connected to the slider 15, the slider 15 can drive the air outlet pipe 21 to move together, and the air outlet pipe 21 slides along the annular groove 23. When the slider 15 moves upward (such as Fig.14As shown in the figure, the slider 15 will drive the air outlet pipe 21 to move upward, prompting the bottom end of the air outlet pipe 21 to pull the annular airbag 18 to move upward. Since the top of the annular airbag 18 conflicts with the second ring 13, the bottom of the air outlet pipe 21 will pull the bottom of the annular airbag 18 to move upward, thereby squeezing the annular airbag 18. At this time, the gas inside the annular airbag 18 enters the air outlet pipe 21 and is discharged from the air outlet pipe 21. The gas enters the through groove 121 through the movable groove 164 and the straight groove 161 and is blown out from the port of the through groove 121. Therefore, when the knocking column 122 moves into the through groove 121, the through groove 121 is blown outward, and the wind force is used to effectively prevent flour from entering the through groove 121, thereby reducing the situation of flour entering the through groove 121, which is conducive to increasing the knocking effect of the knocking column 122, making the vibration generated by the knocking column 122 when knocking more obvious, and further improving the flour feeding efficiency;

[0055] When the slider 15 is reset, the slider 15 moves downward, and the slider 15 drives the air outlet pipe 21 to move downward, so that the air outlet pipe 21 is reset. The air outlet pipe 21 moves downward, and the annular airbag 18 loses contact with the top of the annular receiving groove 17. At this time, the gas enters the annular airbag 18 through the air inlet pipe, and the annular airbag 18 is inflated and reset.

[0056] A spiral air guide sheet 25 is provided on the inner wall of the through groove 121, and a ball 26 for sliding on the top of the annular receiving groove 17 is rotatably provided on the top of the annular air bag 18, and the end of the air outlet pipe 21 is provided with a mesh structure; by the provision of the spiral air guide sheet 25, when the gas enters the through groove 121 through the straight groove 161, the gas will blow toward the spiral air guide sheet 25, and at this time, the gas will blow along the direction of the spiral air guide sheet 25, so as to facilitate the gas to be blown out to the outside of the through groove 121, thereby improving the blowing effect; by the provision of the ball 26, it is convenient for the annular air bag 18 to rotate conveniently when it conflicts with the top wall of the annular receiving groove 17, thereby avoiding friction; by providing a mesh structure at the end of the air outlet pipe 21, it is convenient for the gas inside the annular air bag 18 to enter the air outlet pipe 21, thereby facilitating exhaust;

[0057] A first rubber sealing ring 27 is arranged in the annular groove 23, and a second rubber sealing ring 28 is arranged between the end of the straight rod 162 and the spring groove 166; by arranging the first rubber sealing ring 27, it is possible to prevent the gas from being discharged from the annular accommodating groove 17 through the movable groove 164, the special-shaped annular groove 14 and the annular groove 23, thereby preventing air leakage, and a through hole is arranged on the first rubber sealing ring 27 for the air outlet pipe 21 to pass through, and the through hole is sealed with the air outlet pipe 21, and the air outlet pipe 21 drives the first rubber sealing ring 27 to rotate along the annular groove 23, and by arranging the second rubber sealing ring 28, it is possible to prevent the gas from entering the spring groove 166 from the top of the straight groove 161, thereby affecting the blowing effect of the top through groove 121.
