Description

Technical Field

[0001] The invention relates to the technical field of aggregate conveying devices, and in particular to an aggregate conveying device for concrete construction of high bridge piers. Background Art

[0002] Concrete aggregate conveying device is a device used to convey aggregates required for concrete production. Its working principle is to transport aggregates from storage bins or stacking sites to designated locations, such as mixer feed ports, through motor-driven conveyor belts, spiral blades, or by using pneumatic or hydraulic methods. The device can be designed into different forms according to production needs. For example, belt conveyors are suitable for long-distance and large-volume transportation. Aggregates for bridge high pier concrete construction must meet high strength and low porosity requirements, and particle size grading is strictly controlled to adapt to pumping construction. Fine aggregates are mostly made of medium-coarse sand to ensure cohesion, and coarse aggregates have moderate particle size and reduce needle-like particles. At the same time, they need to be clean and continuously graded to ensure the workability and density of concrete, and adapt to the working conditions of vertical transportation and high-altitude pouring in high pier construction. Prior to mixing the concrete of bridge high piers, aggregate conveying devices are usually used to transport aggregates.

[0003] However, the existing technology has the following problems:

[0004] In the aggregate production process of the existing technology, since the aggregate may be mixed with soil, stone powder, debris and dust during mining and transportation, forming fine impurities, the existing aggregate conveying device will convey the impurities mixed in the aggregate to the mixer when conveying the aggregate. The fine impurities in the aggregate may increase the surface area of ​​the aggregate, absorb more water, cause the water-cement ratio of the concrete to be unbalanced, reduce the strength and durability, and may also weaken the adhesion between the aggregate and the cement slurry, aggravating the risk of shrinkage cracking. Especially during vertical transportation in high pier construction, impurities can easily cause pump blockage or aggregate segregation, affecting the pouring density. In addition, the concrete of high piers of bridges has high requirements for the quality of aggregate. The presence of fine impurities in the aggregate will directly affect the quality of the aggregate, and thus affect the quality of the concrete. Summary of the Invention

[0034] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other implementations obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.

[0035] Example 1

[0036] See also Figure 1 - Figure 11 , a bridge high pier concrete construction aggregate conveying device, comprising a first conveyor group 1 and a second conveyor group 2, and also comprising: an impurity removal component 3 for removing fine impurities in the aggregate during the conveying process; the impurity removal component 3 comprises a mounting frame 31, the mounting frame 31 is located between the first conveyor group 1 and the second conveyor group 2, the first conveyor group 1 is higher than the second conveyor group 2, a screen 32 is slidably mounted on the mounting frame 31, side plates 33 are fixedly mounted on the top of both sides of the mounting frame 31, and a first short shaft 34 and a second short shaft 35 are rotatably mounted on the side plates 33; the first conveyor group 1 and the second conveyor group 2 are both existing technologies for conveying aggregate, Figure 1 For directional reference, the first conveyor group 1 is located on the right side of the mounting frame 31, and the second conveyor group 2 is located on the left side of the mounting frame 31. The top surface of the mounting frame 31 and the screen 32 are both inclined to the lower left. Therefore, when the aggregate is conveyed from right to left, after the aggregate leaves the first conveyor group 1, the aggregate slides down to the left along the inclined screen 32 to the second conveyor group 2, and the second conveyor group 2 continues to convey the aggregate to the left. In the process of the aggregate passing through the screen 32, fine impurities mixed in the aggregate will fall into the mounting frame 31 through the screen 32. A collection box is provided in the mounting frame 31 to collect the fine impurities.

[0037] Furthermore, the second conveyor group 2 includes a conveying roller 21, and the two ends of the conveying roller 21 are fixedly connected to the first gear 36, and the outer walls of the two first short shafts 34 are fixedly connected to the second gears 37. The two first gears 36 are respectively engaged with the two second gears 37. A belt 38 is connected between the first short shaft 34 and the second short shaft 35 on the side plate 33. The outer wall of one of the first short shafts 34 is fixedly connected to the inclined wheel 39, and the screen 32 is fixedly connected to the fork 310. When the inclined wheel 39 rotates, it drives the fork 310 to move back and forth. When the fork 310 moves back and forth, it can drive the screen 32 to shake, thereby promoting the sliding of aggregate above the screen 32 and the falling of fine impurities.

[0038] Furthermore, the downward flipping assembly 4 is used to flip the aggregate in the process of removing fine impurities; the downward flipping assembly 4 includes a movable frame 43, two first short shafts 34 and two second short shafts 35 are respectively fixedly connected with cams 41, the cam 41 is connected to a first pin shaft 42, and the four first pin shafts 42 are all rotatably connected to the movable frame 43, and two groups of mounting shafts 44 are rotatably connected through the movable frame 43, and the bottom of the mounting shaft 44 is fixedly connected to a base 45, and a plurality of shifting rods 46 are fixedly connected to the base 45. The four cams 41 drive the movable frame 43 to revolve clockwise in a circular motion trajectory through the four first pin shafts 42, and the two groups of mounting shafts 44 on the movable frame 43 drive the plurality of shifting rods 46 to revolve synchronously with the movable frame 43 through the base 45. During the clockwise revolution, the plurality of shifting rods 46 contact the aggregate on the screen 32 and shift the aggregate downward, so as to avoid some aggregate staying on the screen 32 for a long time and causing blockage.

[0039] In addition, a slide 49 is slidably connected to the movable frame 43, a turntable 47 is fixedly connected to the first pin 42, a second pin 48 is connected to the turntable 47, a group of slot rods 410 are fixedly connected to the slide 49, a protruding rod 411 is fixedly connected to the top of the mounting shaft 44, a third pin 412 is connected to the protruding rod 411, the second pin 48 is eccentrically arranged on the turntable 47, two slide grooves are provided on the slide 49, the two slide grooves on the slide 49 are slidably connected to the two second pins 48 near the slide 49, a slide groove is provided on the slot rod 410, and the slide grooves on the two groups of slot rods 410 are respectively slidably connected to the third pins 412 above the two groups of mounting shafts 44 Then, when the four turntables 47 rotate, they can drive the two slides 49 to slide back and forth on the movable frame 43 through the four second pins 48. When the slide 49 moves, it drives the slot rod 410 above it to move synchronously. When the slot rod 410 moves back and forth, it can use the cooperation between the slide groove above it and the third pin 412 to drive the protruding rod 411 and the mounting shaft 44 to swing back and forth. When the mounting shaft 44 swings back and forth, it drives the multiple shifting rods 46 to swing back and forth through the base 45. Therefore, the multiple shifting rods 46 under the movable frame 43 can swing back and forth while shifting the aggregate, thereby turning the aggregate and further promoting the falling of fine impurities between the aggregates.

[0040] It is worth noting that the side push assembly 5 is used to prevent aggregate from piling up on both sides of the second conveyor group 2; the side push assembly 5 includes two sliding shafts 51, the two sliding shafts 51 are respectively slidably connected to the two side plates 33, the two side plates 33 are respectively fixedly connected with fixed blocks 52, springs are respectively connected between the two fixed blocks 52 and the two sliding shafts 51, two side push plates 54 are rotatably installed on the mounting frame 31, the side push plates 54 are provided with inclined slide grooves, the sliding shaft 51 is fixedly connected with a dial shaft 53, the two dial shafts 53 are respectively slidably connected with the inclined slide grooves on the two side push plates 54, and when the dial shaft 53 moves left and right, it slides in the inclined slide grooves of the side push plates 54 and drives the side push plates 54 to swing back and forth through the inclined slide grooves. The two first short shafts 34 The cam 41 is in sliding contact with the two sliding shafts 51 during movement. When the sliding shaft 51 is in contact with the cam 41, the sliding shaft 51 slides along the surface of the cam 41, causing the sliding shaft 51 to move to the left. When the sliding shaft 51 is not in contact with the cam 41, the sliding shaft 51 is reset to the right by the spring on the fixed block 52. The second conveyor unit 2 includes a conveyor belt, and the two side push plates 54 are mirror-imaged. The two side push plates 54 are respectively located above both sides of the conveyor belt. When the aggregate that slides down the screen 32 and onto the second conveyor unit 2 passes through the two side push plates 54, the two side push plates 54 push the aggregate at the edges of the conveyor belt on both sides to the middle of the conveyor belt to avoid local aggregate being stuck between the edge of the conveyor belt and the baffle 22, causing local blockage.

[0041] It is worth noting that the second conveyor group 2 also includes two baffles 22, which are respectively located on both sides of the conveyor belt. Elastic sheets 57 are respectively fixedly connected to the two baffles 22. The two side push plates 54 are respectively connected to elastic plates 55 on the sides away from each other through springs. The elastic plates 55 are fixedly connected to the sides close to the side push plates 54 with multiple hammers 56. The two elastic plates 55 are respectively in sliding contact with the two elastic sheets 57 during movement. The elastic plates 55 rebound after contacting the elastic sheets 57. The multiple hammers 56 on the elastic plates 55 hit the side push plates 54, causing the side push plates 54 to vibrate. The side push plates 54 vibrate when pushing the aggregate and can transmit the vibration to the contacted aggregate, so that the aggregate can be evenly distributed when pushed, thereby avoiding local accumulation of aggregate.

[0042] With the above structure, the working principle of this case is that the first conveyor group 1 and the second conveyor group 2 are both existing technologies, which are used to convey aggregates. Figure 1 For directional reference, the first conveyor group 1 is located on the right side of the mounting frame 31, and the second conveyor group 2 is located on the left side of the mounting frame 31. The top surface of the mounting frame 31 and the screen 32 are both inclined to the lower left. Therefore, when the aggregate is conveyed from right to left, after the aggregate leaves the first conveyor group 1, the aggregate slides down to the left along the inclined screen 32 to the second conveyor group 2, and the second conveyor group 2 continues to convey the aggregate to the left. In the process of the aggregate passing through the screen 32, fine impurities mixed in the aggregate will fall into the mounting frame 31 through the screen 32. A collection box is provided in the mounting frame 31 to collect the fine impurities.

[0043] When the conveyor belt in the second conveyor unit 2 is running, the conveying roller 21 rotates accordingly. The conveying roller 21 drives the two second gears 37 to rotate through the two first gears 36. The two second gears 37 drive the two first short shafts 34 to rotate. The two first short shafts 34 drive the two second short shafts 35 to rotate through the two belts 38, so that the two first short shafts 34 and the two second short shafts 35 can rotate synchronously. When the two first short shafts 34 and the two second short shafts 35 rotate synchronously, they respectively drive the four cams 41 to rotate synchronously. When the cam 41 connected to the bevel wheel 39 rotates, it drives the bevel wheel 39 to rotate. When the bevel wheel 39 rotates, it drives the shift fork 310 to reciprocate. When the shift fork 310 reciprocates, it can drive the screen 32 to shake, thereby promoting the sliding of aggregate above the screen 32 and the falling of fine impurities.

[0044] The four cams 41 drive the movable frame 43 to revolve clockwise in a circular motion trajectory through the four first pins 42. The two sets of mounting shafts 44 on the movable frame 43 drive multiple shifting rods 46 to revolve synchronously with the movable frame 43 through the base 45. The multiple shifting rods 46 come into contact with the aggregate on the screen 32 during the clockwise revolution and shift the aggregate downward to prevent some aggregate from staying on the screen 32 for a long time and causing blockage. When the first pin 42 rotates, since the movable frame 43 only revolves, the turntable 47 on the first pin 42 and the movable frame 43 rotate relative to each other (when the movable frame 43 is regarded as stationary, the turntable 47 is in a rotating state). When the turntable 47 rotates, the cooperation between the second pin 48 and the slide groove on the slide 49 drives the slide 49 to move in the movable frame. The four turntables 47 can slide back and forth on the movable frame 43. Therefore, when the four turntables 47 rotate, the four second pins 48 can drive the two slides 49 to slide back and forth on the movable frame 43. When the slide 49 moves, it drives the slot rod 410 above it to move synchronously. Taking one of the mounting shafts 44, the protruding rod 411 and the third pin 412 as an example, when the slot rod 410 moves back and forth, it can use the cooperation between the sliding groove above it and the third pin 412 to drive the protruding rod 411 and the mounting shaft 44 to swing back and forth. When the mounting shaft 44 swings back and forth, it drives multiple shifting rods 46 to swing back and forth through the base 45. Therefore, the multiple shifting rods 46 under the movable frame 43 can swing back and forth while shifting the aggregate, thereby turning the aggregate and further promoting the falling of fine impurities between the aggregates.

[0045] When the cams 41 on the two first short shafts 34 rotate one circle, the cams 41 contact the two sliding shafts 51 respectively. When the sliding shaft 51 contacts the cam 41, the sliding shaft 51 slides along the surface of the cam 41, causing the sliding shaft 51 to move left. When the sliding shaft 51 does not contact the cam 41, the sliding shaft 51 is reset to the right by the spring on the fixed block 52. When the sliding shaft 51 moves left and right, it drives the dial shaft 53 to move left and right. When the dial shaft 53 moves left and right, it slides in the inclined slide groove of the side push plate 54 and drives the side push plate 54 to swing back and forth through the inclined slide groove, so that the two dial shafts 53 can drive the two side push plates 54 to swing back and forth during the left and right reciprocating movement. When the aggregate material that slides down the screen 32 onto the second conveyor unit 2 passes through the two side push plates 54, the two side push plates 54 push the aggregate located at the two sides of the conveyor belt to the middle of the conveyor belt to avoid local aggregate being stuck between the edge of the conveyor belt and the baffle 22, causing local material blockage; the side push plates 54 are in front. When the spring 55 is in contact with the spring plate 57, the spring 57 is compressed, and then the spring plate 57 slides into the spring plate 55 by the inclined surface, thereby locking the spring plate 55. When the spring plate 55 is away from the spring plate 57, the spring plate 57 generates a pulling force on the spring plate 55, so that the spring on the spring plate 55 is stretched, and then the spring plate 55 slides along the inclined surface of the elastic plate 57 and then separates from the elastic plate 57. At this time, the spring plate 55 rebounds, and the multiple hammers 56 on the elastic plate 55 hit the side push plate 54, causing the side push plate 54 to vibrate. The side push plate 54 vibrates when pushing the aggregate, which can transmit the vibration to the aggregate it contacts, so that the aggregate can be evenly distributed when pushed, avoiding local accumulation of aggregate.

[0046] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
