Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, and in particular to a conveying device for low-carbon concrete raw materials. Background Technology

[0002] Low-carbon concrete technology no longer uses a single material, but rather combines multiple auxiliary cementitious materials (SCMs) (such as fly ash, slag powder, limestone powder, etc.) according to performance requirements to form a "composite cementitious material system". Through synergistic effects, it achieves a 1+1>2 effect, while ensuring or even improving performance, and minimizing cement usage and carbon emissions. In the concrete processing process, various raw materials need to be poured onto a conveying device by a conveyor truck, and then transported to the equipment required for the next step of the work.

[0003] According to the description of the existing Chinese patent publication number CN216470307U, a raw material conveying device for concrete is used. The device mainly adds raw materials to the hopper through a feed pipe and a feed hopper. Since the feed pipe or feed hopper does not have a partition structure, the raw materials added to the feed hopper will directly connect to the conveyor belt through the feed pipe during feeding. The weight of the accumulated materials can easily cause the conveyor belt to jam, thereby affecting the conveyor belt's ability to transport raw materials.

[0004] Therefore, it is necessary to provide a new conveying device for low-carbon concrete raw materials to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a conveying device for low-carbon concrete raw materials.

[0006] The conveying device for low-carbon concrete raw materials provided by this utility model includes: a base plate and a belt conveyor. The base plate is equipped with a protective shell that supports the belt conveyor, and a feeding component is provided on one side of the top of the protective shell.

[0007] The feeding assembly includes a feeding hopper, which is fixedly installed on the top of the base plate. A connecting hose is installed between the bottom of the feeding hopper and the inside of the protective shell. The two sides inside the feeding hopper are provided with mounting grooves and sliding grooves.

[0008] An inclined plate for sealing the inside of the loading hopper is slidably installed inside the mounting groove, and a cylinder is fixedly connected between the inclined plates on both sides and the outer wall of the unloading hopper. The inclined plates on both sides abut against the side walls inside the loading hopper.

[0009] Preferably, a feeding assembly is provided on the side of the bottom of the protective shell away from the feeding hopper. The feeding assembly includes a feeding hopper and a mounting plate. The mounting plate is fixedly connected to the protective shell. An annular groove is provided at the bottom of the mounting plate, and a rotating motor is fixedly installed at the center of the bottom of the mounting plate.

[0010] Preferably, the output end of the rotary motor is provided with a fixedly connected mounting bracket, and a fixedly connected linkage bracket is installed on the mounting bracket. The top end of the support rod in the linkage bracket abuts against and is slidably connected to the inner wall of the annular groove. The mounting bracket and the hopper are rotatably connected through a shaft, and a motor that drives the hopper to rotate is fixedly installed on the outer wall of the mounting bracket.

[0011] Preferably, the conveyor belt of the belt conveyor is fixedly installed with multiple evenly distributed baffles, and the sidewalls of the baffles abut against and slide against the inner wall of the protective shell.

[0012] Preferably, the top of the protective shell has a feeding trough on the side near the feeding hopper, and the feeding trough is connected to the connecting hose.

[0013] Preferably, a fixedly connected support column is installed on the top side of the base plate near the feeding hopper, and a movably connected hydraulic rod is provided between the top side of the base plate away from the support column and the protective shell. Both ends of the hydraulic rod are provided with fixedly connected adapter sleeves to the top of the support column. A rotatably connected support frame is inserted inside the adapter sleeve, and the support frame is fixedly connected to the corresponding base plate and protective shell.

[0014] Preferably, a clearing component is inserted between the two sides of the slide groove. The clearing component includes a deflector frame, which is slidably inserted between the two sides of the slide groove. The outer wall of the deflector frame is provided with a hook rod fixedly connected in the area inside the feeding hopper. Both sides of the outer wall of the deflector frame are fixedly connected with sealing plates, and the outer wall of the sealing plate abuts against and is slidably connected to the outer wall of the feeding hopper.

[0015] Compared with related technologies, the conveying device for low-carbon concrete raw materials provided by this utility model has the following beneficial effects:

[0016] 1. This utility model, through the setting of the inclined plate in the feeding assembly, can initially block the discharge port of the feeding hopper during feeding, thereby allowing the raw material to accumulate in the feeding hopper and not come into contact with the belt conveyor. Then, as needed, the cylinder can be controlled to drive the inclined plate to unfold outward, releasing the blockage. At this time, the raw material can fall continuously and slowly onto the belt conveyor under the action of gravity, thereby reducing the probability of the belt conveyor being jammed and damaged due to the weight of the accumulated raw material when all the raw material falls onto the belt conveyor at once during feeding.

[0017] 2. By setting up the feeding component, this utility model allows for the adjustment of the angle of the feeding hopper in the feeding component during the installation and use process when an angle deviation occurs during the docking and installation of the device with subsequent components. This ensures that the feeding end of the feeding hopper can smoothly correspond to the required position of the external docking component without adjusting the position of the entire device. Therefore, it can improve the flexibility of docking this device with external equipment during installation.

[0018] 3. In the feeding process of this utility model, when the raw material in the feeding hopper becomes clogged, the operator can use the lever to push the hook rod upward so that the hook rod is inserted into the raw material from below, and then push the hook rod downward to bring the raw material at the bottom down, causing the raw material to loosen. At this time, the loosened raw material can fall down smoothly, thus allowing the clogged raw material to be fed smoothly.

[0019] 4. By setting up a baffle on the belt conveyor, this utility model can block the raw materials on the belt conveyor when the belt conveyor is conveying in an inclined direction during use, thereby reducing the phenomenon of raw materials falling back due to gravity during conveying, and thus improving the stability of the belt conveyor for conveying raw materials.

[0020] 5. By covering the belt conveyor with a protective shell, this utility model can reduce the occurrence of raw materials falling off the belt conveyor during the conveying process, thereby reducing the safety hazards caused by falling raw materials during the use of this device.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 7 The present invention provides a conveying device for low-carbon concrete raw materials. The conveying device for low-carbon concrete raw materials includes: a base plate 1 and a belt conveyor 3. The base plate 1 is equipped with a protective shell 2 to support the belt conveyor 3, and a feeding component 4 is provided on one side of the top of the protective shell 2.

[0032] In the embodiments of this utility model, please refer to Figures 1 to 7 The feeding assembly 4 includes a feeding hopper 41, which is fixedly installed on the top of the base plate 1. A connecting hose 42 is provided between the bottom of the feeding hopper 41 and the inside of the protective shell 2. The feeding hopper 41 has a mounting groove 411 and a sliding groove 412 on both sides inside. An inclined plate 413 for sealing the inside of the feeding hopper 41 is slidably installed inside the mounting groove 411. A cylinder 414 is fixedly connected between the inclined plates 413 on both sides and the outer wall of the feeding hopper 51. The inclined plates 413 on both sides abut against the side walls inside the feeding hopper 41. A clearing assembly 6 is inserted between the sliding grooves 412 on both sides. The clearing assembly 6 includes a toggle frame 61, which is slidably inserted between the sliding grooves 412 on both sides. A hook rod 63 is fixedly connected to the area inside the feeding hopper 41 on the outer wall of the toggle frame 61. A sealing plate 62 is fixedly connected to both sides of the outer wall of the toggle frame 61, and the outer wall of the sealing plate 62 abuts against and is slidably connected to the outer wall of the feeding hopper 41.

[0033] It should be noted that during feeding, the inclined plate 413 located inside the feeding hopper 41 can block the discharge port of the feeding hopper 41, so that the raw material can accumulate inside the feeding hopper 41 and not come into contact with the belt conveyor 3. Then, the operator can control the cylinder 414 to drive the inclined plate 413 to unfold outward and release the blockage. At this time, the raw material can fall continuously and slowly onto the belt conveyor 3 under the action of gravity, thereby reducing the probability of the raw material accumulating on the belt conveyor 3 due to the weight of the accumulated raw material during feeding.

[0034] Furthermore, during the feeding process, when the raw material in the feeding hopper 41 becomes clogged, the operator can use the lever 61 to push the hook rod 63 upward, so that the hook rod 63 is inserted into the raw material from below, and then push the hook rod 63 downward to bring the raw material at the bottom down, causing the raw material to loosen. At this time, the loosened raw material can fall down smoothly, thus allowing the clogged raw material to be fed smoothly.

[0035] In the embodiments of this utility model, please refer to Figures 1 to 7 The bottom of the protective shell 2 is provided with a feeding assembly 5 on the side away from the feeding hopper 41. The feeding assembly 5 includes a feeding hopper 51 and a mounting plate 52. The mounting plate 52 is fixedly connected to the protective shell 2. The bottom of the mounting plate 52 is provided with an annular groove 521. A rotating motor 522 is fixedly installed at the center of the bottom of the mounting plate 52. The output end of the rotating motor 522 is provided with a fixedly connected mounting bracket 54. A fixedly connected linkage bracket 53 is installed on the mounting bracket 54. The top of the support rod in the linkage bracket 53 abuts against and slides against the inner wall of the annular groove 521. The mounting bracket 54 and the feeding hopper 51 are rotatably connected by a shaft. A motor that drives the feeding hopper 51 to rotate is fixedly installed on the outer wall of the mounting bracket 54.

[0036] It should be noted that during installation and use, if an angle deviation occurs during the docking installation between the device and subsequent components, the angle of the feeding hopper 51 in the feeding assembly 5 can be adjusted so that the feeding end of the feeding hopper 51 can smoothly correspond to the required position of the external docking component. There is no need to adjust the position of the entire device, thus improving the flexibility of docking this device with external equipment during installation.

[0037] In this embodiment, both the rotating motor 522 and the motor driving the hopper 51 are self-locking motors. Therefore, after adjusting the position of the hopper 51 during later use, the hopper 51 can stably guide the falling raw materials.

[0038] In the embodiments of this utility model, please refer to Figures 1 to 7Multiple evenly distributed baffles 31 are fixedly installed on the conveyor belt of the belt conveyor 3, and the side wall of the baffle 31 abuts against and slides against the inner wall of the protective shell 2.

[0039] It should be noted that during the conveying process, when the inclination angle of the belt conveyor 3 is relatively large, the baffle 31 can block the raw material located on the belt conveyor 3, thereby reducing the phenomenon of the raw material falling back due to gravity during conveying, and thus improving the stability of the belt conveyor 3 in conveying the raw material.

[0040] In the embodiments of this utility model, please refer to Figures 1 to 7 The protective shell 2 has a feeding trough 21 on the side of the top of the protective shell 2 near the feeding hopper 41, and the feeding trough 21 is connected to the connecting hose 42. The bottom plate 1 has a fixedly connected support column 11 installed on the side of the top of the bottom plate 1 near the feeding hopper 41. The bottom plate 1 has a movably connected hydraulic rod 12 between the side of the top of the bottom plate 1 away from the support column 11 and the protective shell 2. Both ends of the hydraulic rod 12 and the top of the support column 11 are fixedly connected to the adapter sleeve 13. The adapter sleeve 13 has a rotatably connected support frame 14 inserted inside, and the support frame 14 is fixedly connected to the corresponding bottom plate 1 and protective shell 2.

[0041] It should be noted that: by using the movable erection of the hydraulic rod 12, during installation, the lifting of the protective shell 2 by the hydraulic rod 12 can drive the protective shell 2 and the belt conveyor 3 inside to tilt, thereby enabling this device to be used with parts of various heights.

[0042] It should also be noted that: by setting up the connecting hose 42, when the protective shell 2 rotates with the lifting of the hydraulic rod 12 during use, the connecting hose 42 will rotate synchronously with the protective shell 2, and the protective shell 2 and the hopper 51 will always be in a state of communication.

[0043] By connecting the hopper 51 to the base plate 1, when the raw material hopper is added to the hopper 51 during use, its entire weight can be directly applied to the base plate 1, and will not be applied to the hydraulic rod 12 through the protective shell 2, thereby reducing the lateral pressure on the hydraulic rod 12.

[0044] The working principle of the conveying device for low-carbon concrete raw materials provided by this utility model is as follows:

[0045] When using this device, it can be moved to the desired position by means of the rollers (not shown in the figure). Then, the hydraulic rod 12 can be extended as needed. The extended hydraulic rod 12 will lift the end of the protective shell 2 away from the support column 11, so that the protective shell 2 can rotate with the connection part with the support column 11 as the node, thereby adjusting the tilt angle of the belt conveyor 3 inside the protective shell 2.

[0046] After the feeding end of the belt conveyor 3 moves above the corresponding external component, the rotating motor 522 can be controlled to drive the mounting frame 54 and the external feeding hopper 51 to rotate horizontally as needed. Then, the motor can be controlled to drive the feeding hopper 51 to rotate vertically, thereby adjusting the horizontal and vertical angles of the feeding hopper 51 so that the end of the feeding hopper 51 can smoothly correspond to the feeding end of the corresponding external component. This allows the raw material conveyed by the belt conveyor 3 to be smoothly guided to the corresponding external component, thus completing the installation and adjustment of the device.

[0047] Then, the required concrete raw materials can be added to the inside of the hopper 41 as needed. During this process, the inclined plate 413 in the initial state inside the hopper 41 can block the discharge port of the hopper 41, so that the raw materials can accumulate in the hopper 41 and not contact the belt conveyor 3. Then, the cylinder 414 can be controlled to drive the inclined plate 413 to unfold outward and release the blockage. At this time, the raw materials can fall continuously and slowly onto the belt conveyor 3 under the action of gravity, thereby reducing the probability of the raw materials accumulating on the belt conveyor 3 due to the weight of the accumulated raw materials.

[0048] At this time, the working belt conveyor 3 can drive the baffle 31 to rotate. The rotating baffle 31 can transport the falling material, so that the material can be smoothly transported outward through the feeding component 5. During the conveying process, the baffle 31 can block the material on the belt conveyor 3, thereby reducing the phenomenon of the material falling back due to gravity during the conveying process. This can improve the stability of the belt conveyor 3 in conveying the material. The protective shell 2 located outside the belt conveyor 3 can also reduce the phenomenon of the material falling off the belt conveyor 3 during the conveying process, thereby reducing the safety hazards caused by the falling material during the use of this device.

[0049] Meanwhile, during the feeding process, when the raw material in the feeding hopper 41 becomes clogged, the operator can use the lever 61 to push the hook rod 63 upward, so that the hook rod 63 is inserted into the raw material from below, and then push the hook rod 63 downward to bring the raw material at the bottom down, so that the raw material will loosen. At this time, the loosened raw material can fall down smoothly, and the clogged raw material can be fed smoothly.

[0050] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0051] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
