Description

Technical Field

[0001] This disclosure belongs to the field of road construction conveying technology, specifically relating to a municipal road construction material conveying equipment. Background Technology

[0002] On road construction sites, segmented construction is often used because the transportation environment is limited and transport vehicles cannot reach the designated location. When transporting heavy materials, such as bagged cement, the materials need to be stacked together. Then, the construction workers throw the stacked bagged cement onto the conveyor belt of the conveyor device, which then transports the materials to the designated location.

[0003] Generally, belt conveyors are used to transport bagged cement. However, some raw material storage points are far from the usage points, so another transport mechanism is needed to operate simultaneously. This increases the transportation cost of cement bags, and it is difficult for the two belt conveyors to quickly connect during the handling process, which affects work efficiency. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to provide a municipal road construction material conveying equipment that can solve the problems of increased transportation costs for cement bags and difficulty in quickly connecting two belt conveyors during the handling process, which affects work efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0039] See also Figures 1-8 As shown, according to Embodiment 1 of the present invention, a municipal road construction material conveying device is provided, including: a conveying support 1, two rotating shafts 2 are rotatably connected to the inner side of the conveying support 1, a number of fixed conveyor belts 3 are wound on the two rotating shafts 2, and a gap is left between two adjacent fixed conveyor belts 3.

[0040] The conveyor support 1 has grooves 4 on both opposite sides, and a movable conveying mechanism 5 is installed in the grooves 4 for extending the fixed conveyor belt 3.

[0041] An extension mechanism 6 is provided inside the conveying bracket 1 and above the chute 4 for driving the moving conveying mechanism 5.

[0042] A control mechanism 7 is also provided on the side of the chute 4 to control the lifting and lowering of the moving conveyor 5;

[0043] The side wall of the conveyor support 1 is equipped with a linkage mechanism 8, which is used to drive the conveyor belt to rotate.

[0044] In this embodiment, reference Figure 1 A corresponding support leg can be fixedly installed at the bottom of the conveyor support 1 to support the entire conveyor support 1 and make it conform to the initial transport height. A stepper motor is fixedly installed on the side of the conveyor support 1 and its output end is connected to the corresponding rotating shaft 2. When the stepper motor is driven, it will drive the rotating shaft 2 to rotate, which in turn drives the fixed conveyor belt 3 to rotate, so as to transport the bagged cement.

[0045] When it is necessary to unfold the mobile conveyor 5, the extension mechanism 6 is used to unfold the mobile conveyor 5 and move it to a suitable position. Then, the bagged cement transported by the fixed conveyor belt 3 is transported to the mobile conveyor 5. With the help of the linkage mechanism 8, the mobile conveyor 5 is driven to further transport the bagged cement, thereby reducing the number of belt conveyors used and reducing the cost of use.

[0046] When there is a height difference between the initial position and the conveying position, the control mechanism 7 is used to drive the end of the mobile conveying mechanism 5 to be raised, so that it can adapt to the transportation work in various terrains.

[0047] In a further preferred embodiment of the invention, such as Figure 2 and Figure 8 As shown, the mobile conveying mechanism 5 includes two sliders 9, which are slidably connected in two grooves 4. A moving shaft 10 is rotatably connected between the sliders 9. Two outer plates 11 are provided on the side of the conveying bracket 1 away from the moving shaft 10. A moving shaft 2 12 is rotatably connected between the two outer plates 11. A number of mobile conveyor belts 13 are wound between the moving shaft 10 and the moving shaft 2 12. Each mobile conveyor belt 13 is located between two corresponding fixed conveyor belts 3. A support plate 14 is fixedly connected between the bottoms of the two outer plates 11.

[0048] In this embodiment, combined with Figure 1 ,refer to Figure 2 and Figure 8 The stepper motor drives the rotation of one of the rotating shafts, which in turn drives the rotation of the moving shaft 10 through the linkage. This allows the moving shaft 10 to drive the rotation of all the moving conveyor belts 13. After the bagged cement is placed on the fixed conveyor belt 3, it is transported to the initial conveying end of the moving conveyor belt 13. When the moving conveyor belt 13 rotates, it can take over the conveying of the bagged cement from the fixed conveyor belt 3, allowing the bagged cement to be transported to a farther location and increasing the conveying distance of the material conveying equipment.

[0049] In a further preferred embodiment of the invention, such as Figure 2 As shown, the extension mechanism 6 includes a control motor 15, which is fixedly connected to the side of the conveying bracket 1 away from the outer plate 11. The output end of the control motor 15 is fixedly connected to a control screw 16 and extends into the corresponding slide groove 4. The control screw 16 passes through the corresponding slider 9 and is threadedly connected to the slider 9.

[0050] In this embodiment, combined with Figure 1 ,refer to Figure 2 The control motor 15 drives the control screw 16 to rotate, which in turn drives the slider 9 to move, so that the slider 9 can drive the moving shaft 10 to move. In conjunction with the control mechanism 7, the entire moving conveyor mechanism 5 is moved to facilitate the transportation of bagged cement.

[0051] In a further preferred embodiment of the invention, such as Figures 3-7 As shown, the control mechanism 7 includes a rotating rod 17, which is rotatably connected to the side of the corresponding slider 9. A positioning rod 18 is fixedly connected to the outer periphery of the rotating rod 17. The end of the positioning rod 18 extends to the outer plate 11 and is fixedly connected to a positioning block 19. The positioning block 19 is fixedly connected to the corresponding outer plate 11. A support rod 20 is connected to the side of the conveying bracket 1 and located at the outer plate 11. The top side of the support rod 20 is in contact with the corresponding positioning rod 18.

[0052] The control mechanism 7 also includes a bottom groove 21, which is opened at the bottom of the side wall of the conveying support 1. A number of top grooves 22 are opened on the top side wall of the bottom groove 21. A connecting pipe 23 is slidably connected in the top groove 22. A connecting hole 24 is opened at the bottom of the outer periphery of the connecting pipe 23. The bottom of the connecting pipe 23 is closed and the top of the connecting pipe 23 is arc-shaped.

[0053] The rotating rod 17 has a drive groove 25 inside, and a spiral groove 26 is formed on the inner side wall of the drive groove 25. A sliding push block 27 is slidably connected in the spiral groove 26. A cross rod 28 is slidably connected to the side of the rotating rod 17 near the slider 9. The bottom of the cross rod 28 is fixedly connected to the sliding push block 27. A cross groove 29 is formed on the side of the slider 9. The end of the cross rod 28 extends into the cross groove 29. A lower through groove 30 is formed at the bottom of the slider 9. A through pipe 31 is connected between the top of the lower through groove 30 and the cross groove 29.

[0054] A hydraulic push rod 32 is fixedly installed on the bottom side of the conveying bracket 1 near the control motor. A push groove 33 communicating with the bottom groove 21 is opened on the inner bottom side wall of the conveying bracket 1. The telescopic end of the hydraulic push rod 32 extends into the push groove 33 and is slidably connected with the push groove 33.

[0055] In this embodiment, combined with Figure 2 ,refer to Figures 3-7A spring is fixedly connected between the bottom of each connecting tube 23 and the inner bottom side wall of the bottom groove 21, so that the bottom edge of the connecting tube 23 abuts against the inner top side wall of the bottom groove 21. The control motor 15 drives the control screw 16 to rotate, so that the slider 9 slides in the slide groove 4. The two opposite sides of the bottom of the slider 9 are arc-shaped. When the slider 9 moves to the connecting tube 23 located on the bottom top groove 22 of the slide groove 4, the connecting tube 23 will be squeezed downward, so that the top of the corresponding connecting tube 23 passes through the lower through groove 30 at the bottom of the slider 9. The edge of the lower through groove 30 will also squeeze the top side of the connecting tube 23, so that it will be squeezed down again, so that the slider 9 can pass by.

[0056] After the moving conveyor 5 moves to the designated position, the top arc of the corresponding connecting pipe 23 is embedded into the lower through groove 30 at the bottom of the slider 9. Then, the telescopic end of the hydraulic push rod 32 slides in the push groove 33. The telescopic end of the hydraulic push rod 32 is sealed in the push groove 33, and the connecting hole 24 on the side wall of the pressed connecting pipe 23 will connect with the bottom groove 21. At this time, the telescopic end of the hydraulic push rod 32 extends, and the air in the push groove 33 is squeezed into the bottom groove 21, which in turn compresses the air in the bottom groove 21 into the corresponding connecting pipe 23, and then from the connecting... The top of the through pipe 23 enters the lower through groove 30, then enters the through pipe 31 from the lower through groove 30, and is conveyed from the position of the through pipe 31 to the cross groove 29, which increases the air pressure in the cross groove 29, thereby pushing the cross rod 28 to move into the drive slide groove 25, so that the cross rod 28 drives the sliding push block 27 to move, so that the sliding push block 27 can push the inner side wall of the spiral groove 26, so that the rotating rod 17 can rotate, thereby driving the positioning rod 18 to rotate, so that the positioning rod 18 drives the positioning block 19 and the outer plate 11 to rotate upward, thereby raising the position of the end of the moving conveyor;

[0057] At this point, the conveying height of the conveying equipment can be adjusted. When the position of the conveying end is low, the support rod 20 can be removed, the positioning rod 18 can be unrestricted, and the conveying end of the moving conveying mechanism 5 can be rotated downward, which makes it easier to convey materials to positions with different terrain.

[0058] The support rod 20 can be inserted into the side wall of the conveying bracket 1 and fixed by magnetic attraction to facilitate subsequent adjustment.

[0059] In a further preferred embodiment of the invention, such as Figure 4 As shown, the linkage mechanism 8 includes a drive bevel gear 34, which is fixedly connected to the end of the corresponding rotating shaft 2. The drive bevel gear 34 is located inside the side wall of the conveying bracket 1. The end of the slide groove 4 away from the slider 9 is rotatably connected to a transmission shaft 35. The end of the transmission shaft 35 extends through the slider 9 to the inside of the side wall of the conveying bracket 1 and is fixedly connected to a transmission bevel gear 36 that meshes with the drive bevel gear 34.

[0060] The linkage mechanism 8 also includes a bevel gear ring 37, which is rotatably connected inside the slider 9 and sleeved on the transmission shaft 35 and slidably connected to the transmission shaft 35. A linkage bevel gear 38 is fixedly connected to the end of the moving shaft 1. The linkage bevel gear 38 is inserted into the corresponding slider 9 and meshes with the bevel gear ring 37.

[0061] In this embodiment, reference Figure 4 When the stepper motor drives the corresponding rotating shaft 2 to rotate, the rotating shaft 2 drives the drive bevel gear 34 to rotate, which in turn drives the transmission bevel gear 36 to rotate, and then drives the transmission shaft 35 to rotate. The transmission shaft 35 and the bevel gear ring 37 are slidably connected. At this time, the bevel gear ring 37 can rotate with the transmission shaft 35. The bevel gear ring 37 can slide on the transmission shaft 35 according to the movement of the slider 9. The rotation of the bevel gear ring 37 can drive the linkage bevel gear 38 to rotate, so that the moving shaft 10 can rotate accordingly, so as to drive the rotation of the moving conveyor belt 13, and thus transport the bagged cement.

[0062] In a further preferred embodiment of the invention, such as Figure 9 and Figure 10 As shown, a corrugated telescopic tube 39 is fixedly connected to the side of the support rod 20, and a linkage block 40 is fixedly connected to the bottom side of the slider 9. The side of the linkage block 40 near the corrugated telescopic tube 39 is fixedly connected to the corrugated telescopic tube 39. A number of limiting rods 41 are provided between the slider 9 and the linkage block 40. The number of limiting rods 41 are arranged in a ring array around the outer periphery of the corrugated telescopic tube 39. The slider 9 is sleeved on the number of limiting rods 41 and is slidably connected to the limiting rods 41. The support rod 20 is fixedly connected to the limiting rods 41.

[0063] The top of the support rod 20 is provided with a push groove 42, which is L-shaped and connected to the bottom of the corrugated telescopic tube 39. A push rod 43 is slidably connected to the top of the push groove 42. The top of the push rod 43 is in contact with the bottom of the drive shaft 35 and the top of the push rod 43 is arc-shaped. An electric control valve 44 connected to the push groove 42 is fixedly connected to the side of the support rod 20.

[0064] In this embodiment, combined with Figure 1 ,refer to Figure 9 and Figure 10When the mobile conveying mechanism 5 extends outward, the slider 9 slides on the limiting rod 41, thereby squeezing the corrugated telescopic tube 39 fixedly connected to the support rod 20. When the corrugated telescopic tube 39 is squeezed, the air inside will be squeezed into the pushing groove 42, which increases the air pressure in the pushing groove 42. This causes the air pressure in the pushing groove 42 to push the positioning rod 18, which lifts the positioning rod 18 and prevents the cement on the mobile conveyor belt 13 from being damaged due to friction.

[0065] As the positioning rod 18 moves along with the slider 9, the support rod 20 gets closer and closer to the rotating rod 17, which increases the force required to push the positioning rod 18. The air inside the corrugated telescopic tube 39 is also compressed as the slider 9 moves, thus ensuring that the positioning rod 18 is pushed up a certain distance, so that the moving conveyor belt 13 is tilted. When adjusting the moving conveyor belt 13, the bagged cement on the moving conveyor belt 13 can be lifted to avoid contact with the fixed conveyor belt 3 and friction, which would cause the outer bag of the cement to leak due to wear. After the conveying equipment is extended, the electric control valve 44 can be opened and closed by the external controller to depressurize the push trough 42 and make the moving conveying mechanism 5 horizontal to facilitate the conveying of cement bags.

[0066] When the pressure is released, the electric control valve 44 closes when the top plane of the moving conveyor belt 13 is conveyed to the top plane of the fixed conveyor belt 3. When it is extended again in the future, the air pressure can be directly allowed to reach the specified threshold and push the positioning rod 18 upward.

[0067] When the device needs to be shortened, the electric control valve 44 is opened to release the high pressure, and the corrugated telescopic tube 39 will attract the push rod through the push groove 42, thereby causing the positioning rod 18 to move downward, so that the moving conveyor belt 13 rotates downward, avoiding the phenomenon of cement bags being damaged due to friction on the moving conveyor belt 13.

[0068] Working principle: The stepper motor drives the rotation of one of the rotating shafts, which in turn drives the rotation of the moving shaft 10 through the linkage, so that the moving shaft 10 can drive the rotation of all the moving conveyor belts 13. After the bagged cement is placed on the fixed conveyor belt 3, it is transported to the initial conveying end of the moving conveyor belt 13. When the moving conveyor belt 13 rotates, it can take over the conveying of the bagged cement from the fixed conveyor belt 3, so that the bagged cement can be transported to a more distant location.

[0069] The control motor 15 drives the control screw 16 to rotate, which in turn moves the slider 9, allowing the slider 9 to move the moving shaft 10. After the moving conveyor mechanism 5 moves to the designated position, the arc-shaped top of the corresponding connecting pipe 23 is embedded in the lower through groove 30 at the bottom of the slider 9. Then, the telescopic end of the hydraulic push rod 32 slides in the push groove 33. The telescopic end of the hydraulic push rod 32 is sealed in the push groove 33, and the connecting hole 24 on the side wall of the pressed connecting pipe 23 will connect with the bottom groove 21. At this time, the telescopic end of the hydraulic push rod 32 extends, and the air in the push groove 33 is squeezed into the bottom groove, thus allowing... The air in the bottom groove is compressed into the corresponding connecting pipe 23, then enters the lower through groove 30 from the top of the connecting pipe 23, then enters the through pipe 31 from the lower through groove 30, and is transported to the cross groove 29 from the position of the through pipe 31, which increases the air pressure in the cross groove 29, thereby pushing the cross rod 28 to move into the drive slide groove 25, so that the cross rod 28 drives the sliding push block 27 to move, so that the sliding push block 27 can push the inner wall of the spiral groove 26, so that the rotating rod 17 can rotate, thereby driving the positioning rod 18 to rotate, so that the positioning rod 18 drives the positioning block 19 and the outer plate 11 to rotate upward, thereby raising the position of the end of the moving conveyor;

[0070] At this point, the conveying height of the conveying equipment can be adjusted. When the position of the conveying end is low, the support rod 20 can be removed, the positioning rod 18 can be unrestricted, and the conveying end of the moving conveying mechanism 5 can be rotated downward, which makes it easier to convey materials to positions with different terrain.

[0071] The support rod 20 can be inserted into the side wall of the conveying bracket 1 and fixed by magnetic attraction to facilitate subsequent adjustment.

[0072] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

The above are merely preferred embodiments of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
