Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, in particular to a feeding device for water conservancy construction projects. Background Art

[0002] With the development of modern science and technology, water conservancy projects have gradually shifted from traditional manual construction to mechanized construction. The materials supplied to water conservancy projects usually include cement, steel, wood, sand and gravel, etc., which are used to build buildings and structures of water conservancy projects. These materials usually need to be transported at different heights according to the height differences of geographical locations.

[0004] However, when using a conveyor belt to transport building materials at different heights, with the high-frequency vibration of the entire conveying device, lighter building materials are prone to shaking and rolling off the sides of the conveyor belt, resulting in waste of building materials and reduced transportation volume, which in turn affects the transportation efficiency, while heavier building materials are prone to sliding downward and separating due to gravity, causing wear on the belt surface and the risk of heavy objects rolling and hitting. Therefore, a feeding device for water conservancy construction projects is proposed to solve the above-mentioned problems. Summary of the invention

[0034] 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-9 The present invention provides a technical solution: a feeding device for water conservancy construction engineering, including two bottom beams 1, the bottom beams 1 are used to place the entire device on the ground, and connect the supporting structures in the entire device into a whole to improve stability. The driving support part 2 of this case is installed at the tail end of the bottom beam 1 for high-position installation of the conveyor belt. The material transport support part 3 of this case is installed in the middle of the bottom beam 1 to support the climbing path of the height difference transportation of building materials. The loading support part 4 of this case is installed at the front end of the bottom beam 1 for low-position installation of the conveyor belt. The transportation part 5 of this case is installed between the driving support part 2 and the loading support part 4 to adapt to different building materials for height difference transportation. The protection part 6 of this case is installed on the transportation part 5 to adapt to the current building materials during height difference transportation for pressure compensation and prevent rolling. The recovery part 7 of this case is installed on the material transport support part 3 and the loading support part 4 to collect the building materials shaken off to both sides.

[0036] In the present invention, in order to improve the stability and safety of the height difference transportation of the conveying device and avoid the collapse of the conveyor belt surface, the driving support part 2 of the present case includes a support plate 21, and the number of the support plates 21 is two. The two support plates 21 are respectively fixedly connected to the tail ends of the two bottom beams 1, and a support plate 22 is fixedly connected between the top ends of the two support plates 21. A support plate 23 is also fixedly connected between the two support plates 21. The two support plates 21 are fixedly connected to a mounting platform 24 on one side away from each other, and each mounting platform 24 is fixedly connected to two hinged pieces 25. The two support plates 21 are fixedly connected to a mounting arm 26 on one side away from each other. The material transport support part 3 includes two support legs 31 and two support legs 32. The first leg 31 and the second leg 32 are respectively fixedly connected to the two bottom beams 1, and the top ends of the two legs 1 31 and the two legs 2 are fixedly connected with a rectangular frame 33, and the outer walls of the rectangular frame 33 are fixedly connected with U-shaped arms 34 on both sides. The loading support part 4 includes two support plates 2 41, and the two support plates 2 41 are respectively fixedly connected to the front ends of the two bottom beams 1, and one side of the two support plates 2 41 is fixedly connected with an acute-angle arm 42, and the other sides of the two support plates 2 41 are fixedly connected with a support arm 43 and a convex plate 44, and the tops of the two support plates 2 41 are fixedly connected with a guide plate 45 for guiding the construction materials onto the conveyor belt surface, and a support plate 3 46 and a support plate 47 are fixedly connected between the two support plates 2 41.

[0037] In this embodiment, in order to adapt to different building materials, an integrated connection is adopted between the high position and the low position of the conveying device to perform the transition from loading to discharging. The transportation part 5 of this case includes a transmission roller 1 51 and a transmission roller 2 52. A transmission belt 1 53 is transmission-connected between the transmission roller 1 51 and the transmission roller 2 52. The transmission roller 2 52 is rotationally connected between the two support arms 43. A tension roller 1 54 and a rotating roller 55 are rotationally connected between the two mounting arms 26. A tension roller 2 56 is rotationally connected between the acute angle parts of the two acute angle arms 42. The ends of the two acute angle arms 42 are rotationally connected with a belt pressure wheel 57. The belt pressure wheel 57 is used to press the belt surface of the transmission belt 1 53 and does not hinder the passage of building materials. At the same time, a corresponding groove is provided between the guide plate 45 and the belt pressure wheel 57 to ensure the normal rotation of the belt pressure wheel 57 and prevent the building materials from entering the belt pressure wheel 57 and causing wear. The transmission roller 1 51 and the tension roller 1 54 are horizontally aligned. The transmission roller 2 52 and the tension roller 2 56 are horizontally aligned. The horizontal alignment can make the loading and unloading of building materials have a good transition and improve the safety of transportation. The top of the inner wall of the transmission belt 1 53 is successively fitted with the top of the pallet 1 22, the top of the outer wall of the rectangular frame 33, and the top of the pallet 3 46. The bottom of the outer wall of the transmission belt 1 53 is successively fitted with the top of the pallet 23, the bottom of the inner wall of the rectangular frame 33, and the top of the pallet 47. The top of the inner wall of the transmission belt 1 53 is fitted to bypass the top surface of the tension roller 1 54. The top of the outer wall of the transmission belt 1 53 is fitted to bypass the bottom surfaces of the two pressure rollers 57. The bottom of the outer wall of the transmission belt 1 53 is fitted to bypass the top surface of the rotating roller 55. The bottom of the inner wall of the transmission belt 1 53 is fitted to bypass the bottom surface of the tension roller 2 56. The tension roller 1 54, the tension roller 2 56, the rotating roller 55, and the pressure roller 57 can all increase the belt surface tension of the transmission belt 1 53 and increase the friction, so that the transportation of building materials is more stable.

[0038] It is worth noting that in order to prevent the heavier building materials from sliding down and separating, thereby causing the belt surface to wear and rolling, the protection part 6 of this case includes a transmission roller 3 61 and a transmission roller 4 62. The transmission roller 3 61 and the transmission roller 4 62 are connected to each other with a transmission belt 2 63. The transmission belt 2 63 is fixedly connected with a convex pad 64 along its outer wall and arranged in an array. The inner wall of the transmission belt 2 63 is fitted with a special-shaped frame 65. Both ends of the special-shaped frame 65 are inner arc structures. The special-shaped frame 65 is respectively fitted with the transmission roller 3 61 and the transmission roller 4 62 through the inner arc surfaces on both sides. The special-shaped frame 65 forms a supporting force between the transmission roller 3 61 and the transmission roller 4 62, so that the transmission remains in a stable state, and there is no risk of misalignment and proximity between the transmission roller 3 61 and the transmission roller 4 62. Both sides of the special-shaped frame 65 are fixedly connected with convex blocks 66. The transmission belt 2 63 is fitted between the convex blocks 66. The convex blocks 66 are used to limit the curved motion trajectory of the transmission belt 2 63, and also prevent the special-shaped frame 65 from falling from the side. A support rod 68 is arranged between the shaft ends on both sides of the transmission roller 1 51 and the transmission roller 3 61, and the two ends of each support rod 68 are rotatably sleeved on the shaft ends of the transmission roller 1 51 and the transmission roller 3 61 on the same side. The support rod 68 can ensure that the distance between the transmission roller 1 51 and the transmission roller 3 61 remains unchanged. Two hinge pieces 2 are fixedly connected to each support rod 68, and each support rod 68 is hinged to the inner rod end of the hydraulic rod 1 69 through the hinge piece 2. The two sides of the two support rods 68 close to each other are fixedly connected with a connecting rod, and belt rollers are fixedly sleeved on the shaft ends on both sides of the transmission roller 1 51 and the two connecting rods. A transmission belt 67 is transmission-connected between the transmission roller 1 51 and the belt rollers on the connecting rod on the same side, and gears are fixedly sleeved on the shaft ends on both sides of the two connecting rods and the transmission roller 3 61. The gears on the shaft ends on both sides of the transmission roller 3 61 are respectively meshed with the gears on the connecting rod on the same side. The transmission belt 67 cooperates with the gears to enable the transmission belt 1 53 and the transmission belt 2 63 to work synchronously and perform opposite curved motions.

[0039] It is worth noting that in order to prevent the lighter building materials from falling to the sides due to the vibration of the equipment and causing waste, the recycling part 7 of this case includes two receiving boxes 71, and the two receiving boxes 71 are respectively slidably connected to the inner walls of the two U-shaped arms 34. The box openings of the two receiving boxes 71 are set at the top, and the building materials shaken off from both sides are received through the box openings. The bottoms of the two receiving boxes 71 are connected and provided with discharge nozzles 72, and the received building materials are spit out through the discharge nozzles 72 for recycling. The outer walls of the two discharge nozzles 72 are fixedly connected with hinged plates 73, and the two convex plates 44 The sides away from each other are rotatably connected with a rotating shaft 74, and a ring 75 is fixedly sleeved on the two rotating shafts 74. A torsion spring 76 is elastically connected between each ring 75 and the connected convex plate 44. The outer walls of the two rings 75 are fixedly connected with an adjusting arm 77 and a rocker arm 78. The end of each adjusting arm 77 is respectively hinged on the hinge plate 73 on the same side, and the end of each rocker arm 78 is respectively abutted on the outer rod of the hydraulic rod 2 610 on the same side. The rocker arm 78 swings due to the swing of the hydraulic rod 2 610 and prompts the adjusting arm 77 to drive the material receiving box 71 to rise and fall.

[0040] In order to control the synchronous operation of the transmission belt 1 53 and the transmission belt 2 63 in this case through the main power source, a driving motor 8 is installed on the mounting platform 24 of this case, and its model can refer to the YZRE series motor, which is used to provide the main power source of the conveying device. A counterweight block 9 is installed on the other mounting platform 24. The counterweight block 9 is used to balance the weight of the driving motor 8 on the other side to ensure the installation and use stability of the entire device. One end of the transmission roller 1 51 is fixedly connected to the output shaft of the driving motor 8, and the other end of the transmission roller 1 51 is rotatably connected to the counterweight block 9. The outer rod ends of the two hydraulic rods 69 are respectively hinged on the hinge piece 25 on the same side. The hydraulic rod 1 69 supports the support rod 68 and limits the movement trajectory of the support rod 68, while preventing the support rod 68 from shaking due to force.

[0041] Working principle: building materials are loaded from the low position of transmission belt 53, and the driving motor 8 drives the transmission roller 51 to rotate. The transmission belt 53 drives the transmission roller 2 52 to rotate under the tension of tension roller 54, rotating roller 55, tension roller 2 56 and pressure roller 57, so that the transmission belt 53 moves in a curve and transports the building materials upward. The building materials climb the inclined surface of the transmission belt 53, and the rectangular frame 33 plays a role of supporting the belt surface to prevent the problem of belt surface collapse caused by the building materials. The building materials support the belt surface through the pallet 3 46 when loading and through the pallet 1 22 when unloading, which can also prevent the problem of belt surface collapse.

[0042] When facing heavier construction materials, the inner rod of hydraulic rod 1 69 is controlled to extend and the inner rod of hydraulic rod 2 610 is controlled to contract, thereby pushing transmission roller 3 61 and transmission roller 4 62 to move in a curve and approach the inclined belt surface of transmission belt 1 53. The special-shaped frame 65 plays a limiting role in preventing transmission roller 3 61 and transmission roller 4 62 from being misaligned due to push-pull force, thereby causing the transmission belt 2 63 to lose force and be unable to transmit stably. The connection between transmission belt 2 63 and transmission belt 1 53 through the transmission belt 67 and the gear produces synchronous and opposite curvilinear motion, thereby causing the construction materials that are transported upward in an inclined manner to be intermittently squeezed by the convex pad 64 at the same time, thereby reducing the space above the construction materials, so that the construction materials can be stably transported upward under the anti-slip limit state of the convex pad 64, preventing the risk of heavier construction materials sliding down and rolling during climbing, and improving the safety of height-difference transportation of heavier construction materials.

[0043] On the other hand, according to the different sizes of building materials, the extension and retraction degrees of hydraulic rod 1 69 and hydraulic rod 2 610 can be adjusted in real time, so as to better match the squeezing force of building materials of different sizes when climbing, making it easier and more stable to transport heavy materials with high differences. At the same time, when hydraulic rod 2 610 contracts, the thrust generated by hydraulic rod 1 69 will cause hydraulic rod 2 610 to move from inclined to vertical, and push the rocker arm 78 to drive the rotating shaft 74 to rotate, thereby prompting the adjusting arm 77 to rotate upward synchronously and push the material receiving box 71 to slide upward along the inner wall of the U-shaped arm 34, thereby prompting the material receiving boxes 71 on both sides to extend to the upper sides of the transmission belt 1 53 to form a barrier, preventing heavier building materials from falling from both sides and causing damage to the machine and personnel, thereby further improving the safety of heavy material transportation.

[0044] When transporting lighter construction materials, hydraulic rod 1 69 contracts and hydraulic rod 2 610 extends, causing transmission belt 2 63 to move away from transmission belt 1 53. At the same time, hydraulic rod 2 610 is subjected to the pulling force of the contraction of hydraulic rod 1 69 and rotates from a vertical angle to an inclined angle. At this time, the rotating shaft 74 is subjected to the torsion force of the torsion spring 76 and rotates synchronously with the rotation angle of hydraulic rod 2 610, and causes the end of the rocker arm 78 to continuously abut against hydraulic rod 2 610. At the same time, the material receiving box 71 is pulled down by the adjusting arm 77, causing the box opening of the material receiving box 71 to be lower than the two sides of the inclined surface of transmission belt 1 53. When lighter construction materials fall from both sides, they can be promptly received through the box opening of the material receiving box 71 and caused to be discharged from the discharge nozzle 72. During actual use, the construction materials can be recycled by placing a receiving device such as a material cart or a material box outside the discharge nozzle 72, thereby avoiding the problem of falling and wasting construction materials and difficulty in recycling.
