Description

Technical Field

[0001] The present invention relates to the technical field of agricultural product transportation equipment, and particularly relates to a conveying device suitable for rice processing. Background Art

[0002] Rice processing includes stages such as hulling, milling, polishing, color sorting, and packaging. During the processing of rice at different stages, a conveying device is required to convey the rice into the corresponding device. Generally, a conveyor belt or a screw conveyor is used to convey the rice. During the process of using a screw conveyor to convey rice, when the rice gets damp, due to the increase in moisture on the surface of the rice, the adhesion between the rice and the screw conveyor increases, and the resistance for the screw conveyor to convey the rice to move increases. At the same time, the increase in moisture on the surface of the rice makes the fluidity of the rice worse, and the rice is more likely to accumulate in the screw conveyor, resulting in the screw conveyor being blocked and jammed. When the existing screw conveyor is jammed, it needs to be shut down and the feeding pipe of the conveyor is knocked to disperse the agglomerated rice in the blocked area to eliminate the blockage. However, when using this method to loosen the rice, since the rice is already jammed in the screw conveyor, the vibration effect generated by knocking is limited, and it is not easy to directly act on the blocked area of the rice, resulting in a poor effect of loosening the rice and affecting the subsequent rice conveying efficiency. Summary of the Invention

[0003] The present invention provides a conveying device suitable for rice processing to solve the drawback that the existing conveyor cannot directly drive the rice in the blocked area to move after being blocked.

[0006] Further explanation: A second extrusion rod is fixedly connected to the sliding frame. The elliptical disc is located between the second extrusion rod and the first extrusion rod.

The transmission rods are used to squeeze the adjacent arc-shaped blocks. A second spring is fixedly connected between the transmission ring and the rotating shell.

[0009] Further explanation: The thickness of the arc-shaped block gradually changes along its rotation direction, and the side with a larger thickness of the arc-shaped block contacts the side with a smaller thickness of the adjacent arc-shaped block.

[0010] Further explanation: The limiting assembly further includes: a positioning ring, fixedly connected to the first auger, and the positioning ring is slidably connected to the adjusting frame; a plurality of limiting frames distributed circumferentially, all slidably connected to the adjusting frame.

[0015] 2. When driving the first auger and the second auger to vibrate in the present invention, the position of the positioning ring is restricted by the limit frame, so that the first auger and the second auger vibrate in sequence, reducing the total amount of rice vibrated by the first auger and the second auger each time, and further reducing the resistance when driving the rice to vibrate, which is convenient for the first auger and the second auger to drive the rice to vibrate.

[0016] 3. A telescopic sleeve is arranged between the first auger and the second auger in the present invention, so that rice cannot enter the gap between the first auger and the second auger during the relative movement of the first auger and the second auger, reserving the relative movement space of the first auger and the second auger, and ensuring the normal operation of the device.

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] The invention provides a conveying device suitable for rice processing, which is used to solve the problem that when an existing spiral conveying device is blocked during the process of conveying damp rice, it needs to be stopped for cleaning, resulting in low rice conveying efficiency.

[0030] Embodiment 1: A conveying device suitable for rice processing, such as Figures 1-8 As shown, it includes: a frame 1, a feed pipe 2 is fixedly connected to the frame 1, a motor 3 is fixedly connected to the feed pipe 2, the feed pipe 2 is rotatably connected to a rotating shell 4, and the rotating shell 4 and the output shaft of the motor 3 are driven by a pulley and a belt; a first auger 5 is rotatably and slidably connected to the feed pipe 2, and a first spring 6 is fixedly connected between the feed pipe 2 and the first auger 5; a second auger 7 is slidably and rotatably connected to the feed pipe 2, the first auger 5 and the second auger 7 are splined, the second auger 7 is fixedly connected to an adjusting frame 8, and the adjusting frame 8 is slidably connected to the first auger 5; a sliding frame 9 is slidably connected to the rotating shell 4, and the sliding frame 9 is fixedly connected to a first extrusion rod 10; an elliptical disk 11 is fixedly connected to the first auger 5, and the first extrusion rod 10 is used to push the elliptical disk 11 to move; a power component is arranged on the rotating shell 4, and is used to drive the adjusting frame 8 to rotate; a limit component is arranged on the adjusting frame 8, and is used to limit the relative position of the first auger 5 and the second auger 7.

[0031] Further, such as Figures 2-7 and Figure 10 As shown, the first auger 5 is composed of a spiral blade and a round rod, and the second auger 7 is composed of a spiral blade and a round tube. The length ratio of the spiral blade on the first auger 5 to the spiral blade on the second auger 7 is 2:5.

[0032] Further, such as Figure 6 and Figure 7As shown, a second extrusion rod 12 is fixedly connected to the sliding frame 9 , and the elliptical disk 11 is located between the second extrusion rod 12 and the first extrusion rod 10 . The second extrusion rod 12 is used to push the elliptical disk 11 to move toward the first extrusion rod 10 .

[0033] Further, such as Figure 5 and Figure 6 As shown, an elastic member 13 is fixedly connected between the sliding frame 9 and the rotating shell 4 .

[0034] The above scheme provides a way to drive the auger to move back and forth to adjust the position of the blocked rice after the auger is stuck, so that the auger can rotate normally again; a conical shell that is wide at the top and narrow at the bottom is provided on the frame 1, which is convenient for the staff to feed rice, and a feed port is provided on the upper side of the right part of the feeding pipe 2, the conical shell of the frame 1 is connected with the feed port of the feeding pipe 2, and a discharge port is provided on the lower side of the left part of the feeding pipe 2, and the right part inside the feeding pipe 2 is rotatably connected with a rotating shell 4, and the motor 3 is an existing bidirectional motor, and its specific structure is no longer repeated, and the diameter of the pulley on the rotating shell 4 is larger than the diameter of the pulley on the output shaft of the motor 3, so as to reduce the rotation speed of the rotating shell 4.

[0035] The spiral blade of the first auger 5 is located on the left side of the second auger 7, the spiral direction of the spiral blade on the first auger 5 is the same as the spiral direction of the spiral blade on the second auger 7, the first spring 6 is always in a stored force state, the first spring 6 is used to push the first auger 5 to move to the right, and a baffle is provided on the right part of the second auger 7 to prevent the rice from moving to the gap between the right part of the spiral blade on the second auger 7 and the feeding pipe 2; the sliding frame 9 is composed of a piston rod and a fan-shaped plate, and the first extrusion rod 10 is located on the fan-shaped plate of the sliding frame 9. The first extrusion rod 10 contacts the right side of the elliptical disk 11, and the first extrusion rod 10 is used to push the elliptical disk 11 to move to the left. The end of the first extrusion rod 10 close to the elliptical disk 11 is a hemispherical head, which is used to reduce the contact area between the elliptical disk 11 and the first extrusion rod 10, thereby reducing the wear during the relative movement of the two. When not working, the first extrusion rod 10 contacts the lower part of the elliptical disk 11.

[0036] There is an angle between the axis of the elliptical disk 11 and the axis of the first extrusion rod 10; the ratio of the length of the first auger 5 to the second auger 7 is used to reduce the total amount of contact between the first auger 5 and the rice, thereby reducing the resistance of the first auger 5 when it moves; the second extrusion rod 12 is in contact with the right side of the elliptical disk 11, and the second extrusion rod 12 is used to push the elliptical disk 11 to move to the right; the elastic member 13 is a stretchable and compressible spring, which is used to make the first extrusion rod 10 or the second extrusion rod 12 unable to push the elliptical disk 11 to move, so that the first extrusion rod 10 or the second extrusion rod 12 drives the sliding frame 9 to move along the elliptical disk 11, so as to avoid the device from being directly stuck and causing the device to be unusable.

[0037] Further, such as Figures 4-6 andFigure 8 As shown in the figure, the power assembly includes: arc-shaped blocks 14 symmetrically distributed around the center, which are fixedly connected to one side of the adjusting frame 8 close to the rotating shell 4; a transmission ring 15, which is slidably connected inside the rotating shell 4. The transmission ring 15 is fixedly connected with symmetrically distributed transmission rods 16. The transmission rods 16 are slidably connected to the rotating shell 4 and are used to squeeze the adjacent arc-shaped blocks 14. A second spring 17 is fixedly connected between the transmission ring 15 and the rotating shell 4.

[0038] Furthermore, as shown in Figure 5 、 Figure 6 and Figure 8 the figure, the thickness of the arc-shaped block 14 gradually changes along its rotation direction, and the side with a larger thickness of the arc-shaped block 14 contacts the side with a smaller thickness of the adjacent arc-shaped block 14.

[0039] In the above solution, the number of the arc-shaped blocks 14 and the transmission rods 16 in this embodiment is two. When the transmission ring 15 rotates counterclockwise ( Figure 6 , viewed from right to left, hereinafter referred to as forward rotation), the side with a larger thickness of the arc-shaped block 14 will catch the adjacent transmission rod 16, so that the transmission rod 16 drives the arc-shaped block 14 to rotate circumferentially by extrusion. When the transmission ring 15 rotates clockwise ( Figure 6 , viewed from right to left, hereinafter referred to as reverse rotation), the transmission rod 16 rotates along the gradient surface of the arc-shaped block 14 and moves to the right under the action of the gradient surface of the arc-shaped block 14; initially, the left side surface of the transmission ring 15 contacts the rotating shell 4, and the second spring 17 is used to push the transmission ring 15 to move leftward to reset.

[0040] Working process: When using this device to transport rice, the staff moves this device to the rice storage place, and then the staff starts the motor 3. The output shaft of the motor 3 drives the rotating shell 4 to rotate counterclockwise through the belt pulley and the belt ( Figure 2 , viewed from right to left). The rotating shell 4 drives the sliding frame 9 and the transmission ring 15 to rotate synchronously. The sliding frame 9 drives the first extrusion rod 10 and the second extrusion rod 12 to rotate counterclockwise. The transmission ring 15 drives the transmission rod 16 to rotate, so that the transmission rod 16 drives the adjusting frame 8 to rotate by squeezing the adjacent arc-shaped block 14. The adjusting frame 8 drives the second auger 7 to rotate counterclockwise. The second auger 7 drives the first auger 5 to rotate counterclockwise through the spline. The first auger 5 drives the elliptical disk 11 to rotate. At this time, the rotation speed of the elliptical disk 11 is the same as that of the sliding frame 9, that is, there is no relative movement between the first extrusion rod 10 and the second extrusion rod 12 and the elliptical disk 11, and the first auger 5 will not move left and right along its axis. The positions of the first auger 5 and the second auger 7 remain relatively stable.

[0041] After the above-mentioned first auger 5 and second auger 7 start to rotate, the staff feeds rice into the conical shell of the frame body 1. The rice enters the feed pipe 2 through the conical shell. Subsequently, under the action of the second auger 7 and the first auger 5, the rice gradually moves left along the axis direction of the feed pipe 2 and finally discharges from the discharge port of the feed pipe 2.

[0042] As the rice is continuously conveyed, when encountering the part where the rice is damp, as the rice is continuously conveyed, when the first auger 5 and the second auger 7 are stuck due to the increase in conveying resistance. Taking the blockage in the area where the first auger 5 is located as an example, the staff adjusts the rotation direction of the output shaft of the motor 3 to make the output shaft of the motor 3 rotate clockwise ( Figure 2 , as viewed from right to left), the output shaft of the motor 3 drives the rotating shell 4 and the parts thereon to rotate clockwise. The transmission ring 15 drives the transmission rod 16 to rotate clockwise along the gradually changing surface of the arc-shaped block 14. At this time, the transmission rod 16 cannot be stuck by the arc-shaped block 14, and the transmission rod 16 cannot drive the arc-shaped block 14 to rotate, that is, both the first auger 5 and the second auger 7 stop rotating. Under the action of the gradually changing surface on the arc-shaped block 14, the transmission rod 16 drives the transmission ring 15 to move left and right continuously and compress the second spring 17.

[0043] During the process of the above-mentioned rotating shell 4 rotating clockwise, the sliding frame 9 drives the first extrusion rod 10 and the second extrusion rod 12 to rotate synchronously. The first extrusion rod 10 squeezes the elliptical disk 11 to the left, so that the elliptical disk 11 drives the first auger 5 to move to the left and compress the first spring 6. Until the sliding frame 9 rotates 180°, the first extrusion rod 10 no longer pushes the elliptical disk 11 to move to the left, and the first auger 5 no longer continues to move to the left and compress the first spring 6. As the sliding frame 9 continues to rotate, at this time, the second extrusion rod 12 squeezes the elliptical disk 11 to the right, so that the first auger 5 moves to the right and resets under the combined action of the elliptical disk 11 and the first spring 6. Until the sliding frame 9 rotates 180° again, the sliding frame 9 resets, and the first auger 5 stops moving to the right and completes the reset. Subsequently, the sliding frame 9 continues to rotate, so that the first extrusion rod 10 and the second extrusion rod 12 drive the first auger 5 to move left and right continuously, thereby causing the first auger 5 to vibrate and driving the blocked area of the rice to vibrate together, making the blocked rice gradually loose, so as to relieve the blocked situation. During this process, due to the obstruction of the rice, the first auger 5 cannot move left and right normally, and can only vibrate slightly to loosen the surrounding rice. As the first auger 5 drives the rice to vibrate, the blocked rice gradually loosens, the resistance of the rice to the movement of the first auger 5 gradually decreases, and the moving distance of the first auger 5 gradually increases. When the first auger 5 cannot be normally pushed by the first extrusion rod 10 and the second extrusion rod 12 under the obstruction of the rice, at this time, the sliding frame 9 moves left and right and compresses or stretches the elastic member 13 for buffering, so that the sliding frame 9 rotates normally.

[0044] Until the rice blocked in the corresponding area of the first auger 5 is loosened, the staff activates the limit component to lock the first auger 5 and the second auger 7, so that when the first auger 5 moves left and right, it drives the second auger 7 to move synchronously, thereby realizing the segmented loosening of the blocked rice and reducing the resistance encountered when loosening the rice. Until the rice blocked in the corresponding area of the second auger 7 is completely loosened, the staff turns off the limit component to release the limit on the first auger 5 and the second auger 7. Then, the steering of the output shaft of the motor 3 is adjusted again to make the rotating shell 4 and its parts rotate counterclockwise again. After the transmission rod 16 contacts the thicker side of the arc-shaped block 14, the first auger 5 and the second auger 7 rotate again to convey the rice.

[0045] Embodiment 2: On the basis of Embodiment 1, as Figures 6-9 shown, the limit component further includes: a positioning ring 18, fixedly connected to the first auger 5, and the positioning ring 18 is slidably connected to the adjusting frame 8; a plurality of limit frames 19, which are circumferentially distributed and are all slidably connected to the adjusting frame 8. The limit frames 19 are used to fix the positioning ring 18, and an elastic plate 20 is fixedly connected between adjacent two limit frames 19; a tightening component, arranged on the feed pipe 2, and is used to drive the circumferentially distributed limit frames 19 to move.

[0046] The above solution provides a method for fixing the position of the first auger 5 after it moves left to the maximum movable distance, so that the first auger 5 drives the second auger 7 to reciprocate together; the positioning ring 18 is located at the right part of the round rod of the first auger 5; the cross section of the limit frame 19 is T-shaped, and the cross section of the elastic plate 20 is arc-shaped, and the center of the circle where the arc is located is close to the center of the positioning ring 18. The positioning ring 18 is used to drive the limit frame 19 to move outward and reset. When the limit frame 19 moves towards the axis direction of the positioning ring 18, the elastic plate 20 stores energy and its radian increases, and the innermost side of the limit frame 19 is flush with the inner wall of the adjusting frame 8.

[0047] Furthermore, as Figures 3-5 and Figure 9 shown, the tightening component includes: an electric push rod 23, fixedly connected to the feed pipe 2, the telescopic end of the electric push rod 23 is fixedly connected with a soft rope 24, the soft rope 24 passes through the feed pipe 2, and the soft rope 24 surrounds the circumferentially distributed limit frames 19 and the circumferentially distributed elastic plates 20; a limit ring 25, rotatably connected to the adjusting frame 8, the limit ring 25 is slidably connected to the feed pipe 2, the soft rope 24 is slidably connected to the limit ring 25, and the limit ring 25 is used to control the moving path of the soft rope 24.

[0048] The above solution provides a way to drive the limit frame 19 to move closer to the positioning ring 18; the electric push rod 23 is located at the right part of the feeding pipe 2, and both ends of the soft rope 24 are fixedly connected to the telescopic end of the electric push rod 23. Initially, the telescopic end of the electric push rod 23 is in the extended state, and the soft rope 24 is in a loose state; the limit ring 25 is located at the left part of the adjusting frame 8, and the limit ring 25 is used to gather the soft rope 24, so that the soft rope 24 forms a ring outside the limit frame 19 and the elastic plate 20, and the soft rope 24 can be wound around two to four circles outside the limit frame 19 and the elastic plate 20.

[0049] This working process is carried out on the basis of the working process in Embodiment 1: During the process of the first auger 5 moving left and right alone as described above, the first auger 5 drives the positioning ring 18 to move synchronously. When the positioning ring 18 moves to the left side of the limit frame 19, the first auger 5 completes the loosening of the blocked rice in the corresponding area. The staff starts the electric push rod 23, and the telescopic end of the electric push rod 23 moves to the right and retracts. The telescopic end of the electric push rod 23 pulls the soft rope 24, so that the soft rope 24 located outside the limit frame 19 and the elastic plate 20 gradually tightens. When the lower part of the soft rope 24 contacts the adjacent limit frame 19, the soft rope 24 is completely taut. As the telescopic end of the electric push rod 23 continues to pull the soft rope 24, the soft rope 24 squeezes the limit frame 19 and the elastic plate 20, and the elastic plate 20 deforms and stores energy. The limit frame 19 moves towards the axis direction of the adjusting frame 8, and the limit frame 19 contacts the right side surface of the positioning ring 18. Until the telescopic end of the electric push rod 23 is completely retracted and then it automatically closes. At this time, the soft rope 24 no longer tightens, and the limit frame 19 stops moving and completes the limiting of the adjusting frame 8, so that when the first auger 5 moves, it drives the adjusting frame 8 to move synchronously through the positioning ring 18 and the limit frame 19, and further enables the second auger 7 to move synchronously with the first auger 5, and loosens the blocked rice in the adjacent area. Until the rice in the corresponding area of the second auger 7 is completely loosened, the staff starts the electric push rod 23, and the telescopic end of the electric push rod 23 extends and resets, so that the extrusion force of the soft rope 24 on the elastic plate 20 and the limit frame 19 is reduced, and the elastic plate 20 drives the limit frame 19 to move in the reverse direction and reset, thereby releasing the limit on the positioning ring 18. After that, the output shaft of the motor 3 rotates forward to make the first auger 5 and the second auger 7 convey materials again.

[0050] Embodiment 3: On the basis of Embodiment 2, as Figures 6-8 shown, a support frame 21 is fixedly connected to the rotating shell 4, and a rubber ring 22 is fixedly connected to the side of the support frame 21 close to the adjusting frame 8. The rubber ring 22 is used to squeeze the adjusting frame 8.

[0051] In the above solution, the support frame 21 is located on the left side of the rotating shell 4, and the rubber ring 22 is located on the left side of the support frame 21. During the left and right movement of the second auger 7 and the first auger 5, as the adjusting frame 8 moves to the right, when the adjusting frame 8 contacts the rubber ring 22, the rubber ring 22 and the adjusting frame 8 are mutually extruded. At this time, since the second auger 7 and the first auger 5 do not rotate, the rotating shell 4 drives the rubber ring 22 to rotate clockwise through the support frame 21 ( Figure 6 , as viewed from right to left), so that the rubber ring 22 exerts a frictional force on the adjusting frame 8 in the direction of rotation around its axis, thereby causing the adjusting frame 8 to have a tendency to rotate clockwise. After the force exerted by the rubber ring 22 on the adjusting frame 8 is greater than the resistance when the rice rotates the second auger 7 and the first auger 5, the rubber ring 22 drives the second auger 7 and the first auger 5 to rotate through the adjusting frame 8, thereby adjusting the relative positions between the second auger 7 and the first auger 5 and the rice, and accelerating the loosening of the rice blockage area.

[0052] Example 4: On the basis of Example 3, as Figure 3 , Figure 4 and Figure 10 shown, a telescopic sleeve 26 is fixedly connected between the side of the second auger 7 away from the adjusting frame 8 and the first auger 5.

[0053] In the above solution, the telescopic sleeve 26 is located between the left part of the second auger 7 and the right part of the spiral blade on the first auger 5. The telescopic sleeve 26 is used to protect the left part of the second auger 7 to prevent rice from entering between the right part of the spiral blade on the first auger 5 and the left part of the second auger 7 during the relative movement between the first auger 5 and the second auger 7, resulting in the spiral blade of the first auger 5 being unable to move to the right and reset relative to the second auger 7, affecting the normal use of the device. The telescopic sleeve 26 is in a contracted state initially.

[0054] Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the disclosed exemplary embodiments.
