Description

Technical Field

[0001] This invention relates to the field of conveying device technology, and in particular to a receiving device, a conveying system and a mixing plant. Background Technology

[0002] An inclined belt conveyor is a type of conveying equipment with a loading end at the bottom and a discharge end at the top, used to transport materials from a lower position to a higher position. In some automated production systems, taking a mixing plant as an example, a horizontal belt conveyor is typically installed at the loading end of the inclined belt conveyor. The discharge end of the horizontal belt conveyor is located above the loading end of the inclined belt conveyor. The operation of the horizontal belt conveyor allows it to discharge materials to the loading end of the inclined belt conveyor, thus enabling the inclined belt conveyor to transport materials to a higher position.

[0003] When material is discharged from a horizontal belt conveyor to an inclined belt conveyor, a receiving hopper is typically installed above the loading end of the inclined belt conveyor to minimize material spillage. To prevent leakage from the loading end of the inclined conveyor, the side wall of the receiving hopper away from the unloading end of the inclined belt conveyor needs to be flush with the conveyor to achieve a seal. However, in concrete mixing plants, water inevitably accumulates on horizontal belt conveyors. This water is difficult to clean, and if it participates in the conveying process, it will not only affect the quality of the concrete but also the delivery of the concrete.

[0004] Therefore, how to solve the problem of water accumulation on horizontal belt conveyors in related technologies is not easy to clean, which has become an important technical problem for those skilled in the art to solve. Summary of the Invention

[0008] A sealing mechanism is provided in the receiving hopper. The sealing mechanism can switch between a first state and a second state. In the first state, the sealing mechanism closes the first opening. In the second state, the sealing mechanism opens the first opening.

[0009] According to a material receiving device provided by the present invention, the material receiving hopper includes:

[0010] The receiving hopper body has a second sidewall on the sidewall away from the unloading end of the inclined belt conveyor, and a second opening is formed between the lower edge of the second sidewall and the upper conveying surface.

[0011] A connecting box is disposed outside the receiving hopper body, and the first end of the connecting box is connected to the second side wall. The connecting box is connected to the second opening, the first opening is formed at the second end of the connecting box, and the sealing mechanism is disposed at the second end of the connecting box.

[0012] According to a material receiving device provided by the present invention, the size of the first opening in the direction perpendicular to the upper conveying surface is the first opening size, the size of the second opening in the direction perpendicular to the upper conveying surface is the second opening size, and the second opening size is smaller than the first opening size;

[0015] A first sealing plate is disposed at the first opening, the upper edge of the first sealing plate is rotatably connected to the side wall of the first opening, and in the first state, the lower edge of the first sealing plate is adapted to fit against the upper conveying surface.

[0016] According to a material receiving device provided by the present invention, the sealing mechanism further includes:

[0017] A driving component is disposed between the receiving hopper and the first sealing plate, and the driving component is adapted to drive the first sealing plate to rotate relative to the receiving hopper.

[0018] According to a material receiving device provided by the present invention, the first sealing plate includes:

[0019] A baffle, the upper edge of which is rotatably connected to the sidewall of the first opening;

[0020] A sealing strip is connected to the lower edge of the baffle in a sealing manner, and the sealing strip is in contact with the upper conveying surface.

[0021] The receiving device provided by the present invention further includes:

[0022] The detection module is used to detect the amount of water accumulated on the horizontal belt conveyor and / or the amount of water accumulated in the receiving hopper;

[0023] The control module is electrically connected to both the detection module and the drive component. The control module is adapted to control the operation of the drive component based on the amount of water accumulated on the horizontal belt conveyor and / or the amount of water accumulated in the receiving hopper.

[0024] According to a material receiving device provided by the present invention, the detection module includes a vision camera.

[0026] The present invention also provides a mixing plant, including the above-described receiving device, or including the above-described conveying system.

[0027] The material receiving device provided by this invention includes a receiving hopper and a sealing mechanism.

When the sealing mechanism is switched to the second state, it opens the first opening, allowing material or water from the receiving hopper to discharge downwards along the upper conveying surface of the inclined belt conveyor. With this configuration, when materials need to be conveyed, switching the sealing mechanism to the first state can effectively prevent materials from leaking from the feeding end of the inclined belt conveyor. When water needs to be drained, switching the sealing mechanism to the second state allows the horizontal belt conveyor to operate, and the water can be discharged through the receiving hopper and the first opening.

In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0041] The following is combined with Figures 1 to 3 The receiving device of the present invention is described.

[0042] like Figures 1 to 3 As shown, the receiving device provided in this embodiment of the invention includes a receiving hopper and a sealing mechanism.

[0043] Specifically, the receiving hopper is used to be installed below the discharge end of the horizontal belt conveyor 9, with an open upper end to collect the material from the discharge end of the horizontal belt conveyor 9. The receiving hopper is also used to be installed above the loading end of the inclined belt conveyor 1, with the material in the receiving hopper falling onto the loading end of the inclined belt conveyor 1, thereby allowing the inclined belt conveyor 1 to transport the material to a higher position.

[0044] The side wall of the receiving hopper away from the unloading end of the inclined belt conveyor 1 is the first side wall 10. A first opening 11 is provided on the first side wall 10. The first opening 11 allows the accumulated water in the receiving hopper to flow downward along the upper conveying surface of the inclined belt conveyor 1.

[0045] The sealing mechanism is located at the first opening 11 of the receiving hopper, and the sealing mechanism can switch between the first state and the second state.

[0046] When the sealing mechanism switches to the first state, refer to Figure 1 The sealing mechanism closes the first opening 11, which can limit the leakage of material or water in the receiving hopper at the feeding end of the inclined belt conveyor 1.

[0047] When the sealing mechanism switches to the second state, refer to Figure 2 The sealing mechanism opens the first opening 11, allowing the material or water in the receiving hopper to be discharged downwards along the upper conveying surface of the inclined belt conveyor 1.

[0048] With this configuration, when materials need to be conveyed, switching the sealing mechanism to the first state can effectively prevent materials from leaking from the feeding end of the inclined belt conveyor 1. When water needs to be drained, switching the sealing mechanism to the second state allows the horizontal belt conveyor 9 to run, and the water can be discharged through the receiving hopper and the first opening 11. This facilitates operation and solves the problem of water accumulation on horizontal belt conveyors that is difficult to clean in related technologies.

[0049] In this embodiment of the invention, the receiving hopper includes a receiving hopper body 2 and a connecting box 3.

[0050] The side wall of the receiving hopper body 2 away from the discharge end of the inclined belt conveyor 1 is a second side wall 12. A second opening 13 is formed between the lower edge of the second side wall 12 and the upper conveying surface of the inclined belt conveyor 1. A connecting box 3 is disposed outside the receiving hopper body 2, and the first end of the connecting box 3 is connected to the second side wall 12. The connecting box 3 is connected to the second opening 13. The wall surface of the second end of the connecting box 3 serves as the first side wall 10. The first opening 11 is formed at the second end of the connecting box 3, and a sealing mechanism is disposed at the second end of the connecting box 3.

[0051] Water accumulated in the receiving hopper body 2 enters the connecting box 3 through the second opening 13 and flows out through the first opening 11. The first opening 11 is located on the outside relative to the second opening 13, and its opening and closing can be controlled solely by a sealing mechanism.

[0052] The dimension of the first opening 11 along the direction perpendicular to the upper conveying surface of the inclined belt conveyor 1 is the first opening dimension. Figure 3The dimension of the second opening 13 at the position indicated by b, along the direction perpendicular to the upper conveying surface of the inclined belt conveyor 1, is the dimension of the second opening. (Refer to...) Figure 3 At the location indicated by a, the second opening is smaller than the first opening. This design allows for the smooth drainage of accumulated water while blocking larger particles from flowing into the hopper and preventing them from reaching the connecting housing 3 and the first opening 11, thus reducing the impact on the sealing mechanism.

[0053] Specifically, the connecting box 3 includes a pair of side panels and a top plate. The pair of side panels are arranged facing each other, each side panel is parallel to the conveying direction of the inclined belt conveyor 1, and the distribution direction of the pair of side panels is perpendicular to the conveying direction of the inclined belt conveyor 1. The top plate is fixedly arranged above the pair of side panels, and the upper end of the first sealing plate 4 is rotatably connected to the side of the top plate away from the receiving hopper body.

[0054] In this embodiment, the size of the second opening is set to 20-30 mm, that is, the size of the second opening 13 in the direction perpendicular to the upper conveying surface of the inclined belt conveyor 1 is set to 20-30 mm. Specifically, it can be determined according to the particle size of the material to be conveyed by the inclined belt conveyor 1.

[0055] In a specific embodiment, the dimension of the second opening 13 in the direction perpendicular to the upper conveying surface of the inclined belt conveyor 1 is set to 25 mm.

[0056] The receiving hopper body 2 includes four side plates, which are arranged in a circle and connected sequentially. The side plate corresponding to the second side wall 12 includes a rigid baffle 6 and a rubber plate, with the upper edge of the rubber plate sealingly connected to the lower edge of the rigid baffle 6. The rubber plate reduces the impact of materials on the receiving hopper body 2. Furthermore, the rubber plate effectively reduces the hardness of the lower edge of the second side wall 12. During operation of the inclined belt conveyor 1, the rubber plate prevents wear on the belt caused by belt undulations, thus extending the service life of the inclined belt conveyor 1.

[0057] When connecting the rubber sheet to the rigid baffle 6, the upper edge of the rubber sheet can overlap with the lower edge of the rigid baffle 6, and the rubber sheet and the rigid baffle 6 can be pressed together using bolts and nuts.

[0058] The distance between the lower edge of the rubber plate and the upper conveying surface of the inclined belt conveyor 1 along the direction perpendicular to the upper conveying surface of the inclined belt conveyor 1 can be regarded as the dimension of the second opening 13 along the direction perpendicular to the upper conveying surface of the inclined belt conveyor 1.

[0059] In some embodiments, the rigid baffle 6 is fixedly connected to the other side plates, while the rubber plate is slidably connected to the rigid baffle 6. This allows the rubber plate to move closer to or further away from the upper conveying surface of the inclined belt conveyor 1 relative to the rigid baffle 6, thereby adjusting the distance between the lower edge of the rubber plate and the upper conveying surface of the inclined belt conveyor 1. Before use, after adjusting the distance between the lower edge of the rubber plate and the upper conveying surface of the inclined belt conveyor 1, the connection is tightened using bolts and nuts to fix the rubber plate relative to the rigid baffle 6.

[0060] Specifically, a strip-shaped hole can be provided on the rubber plate, with the length direction of the hole parallel to the distribution direction of the rigid baffle 6 and the rubber plate. The bolt passes through the strip-shaped hole on the rubber plate and is then connected to the rigid baffle 6.

[0061] Multiple strip-shaped holes are provided, spaced apart, with their distribution direction parallel to the upper conveying surface of the inclined belt conveyor 1 and perpendicular to the conveying direction of the inclined belt conveyor 1. Each strip-shaped hole is equipped with a pair of bolts and nuts, and multiple pairs of bolts and nuts are used to connect the rubber plate to the rigid baffle 6.

[0062] In this embodiment, the sealing mechanism includes a first sealing plate 4, which is disposed in the first opening 11. The upper edge of the first sealing plate 4 is rotatably connected to the side wall of the first opening 11. The rotation axis of the first sealing plate 4 relative to the side wall of the first opening 11 is parallel to the upper conveying surface of the inclined belt conveyor 1 and perpendicular to the conveying direction of the inclined belt conveyor 1.

[0063] In the first state, the lower edge of the first sealing plate 4 can fit against the upper conveying surface of the inclined belt conveyor 1.

[0064] With this configuration, the sealing mechanism can be switched between the first state and the second state by rotating the first sealing plate 4 relative to the receiving hopper.

[0065] In this embodiment, the first sealing plate 4 includes a baffle 6 and a sealing strip 7. The upper edge of the baffle 6 is rotatably connected to the side wall of the first opening 11, and the sealing strip 7 is disposed on the lower edge of the baffle 6, and the sealing strip 7 is sealed to the lower edge of the baffle 6. In the first state, the sealing mechanism has the sealing strip 7 in contact with the upper conveying surface of the inclined belt conveyor 1.

[0066] The sealing strip 7 can increase the sealing performance of the sealing mechanism for the first opening 11.

[0067] Moreover, the sealing strip 7 is made of rubber, which is flexible. It comes into contact with the upper conveying surface of the inclined belt conveyor 1, which can reduce the wear on the upper conveying surface of the inclined belt conveyor 1 and help extend the service life of the inclined belt conveyor 1.

[0068] In this embodiment of the invention, the sealing mechanism further includes a driving component 5, which is disposed between the receiving hopper and the first sealing plate 4, and is used to drive the first sealing plate 4 to rotate relative to the receiving hopper. By controlling the action of the driving component 5, the state switching of the sealing mechanism can be realized, which can reduce manual operation and reduce labor intensity.

[0069] The aforementioned driving component 5 may be, but is not limited to, a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, a gear and rack transmission assembly, a lead screw and nut transmission assembly, a belt transmission assembly, etc.

[0070] like Figure 3 As mentioned above, a cylinder is selected as the driving component 5, the cylinder body is hinged to the connecting housing 3, and the piston rod of the cylinder is hinged to the first sealing plate 4. By controlling the extension and retraction of the cylinder, the first sealing plate 4 can be driven to rotate.

[0071] In this embodiment of the invention, the receiving device further includes a detection module and a control module. The detection module is used to detect the amount of water accumulated on the horizontal belt conveyor 9 and / or the amount of water accumulated in the receiving hopper. Before using the inclined belt conveyor 1 to transport materials, it is necessary to detect the amount of water accumulated on the horizontal belt conveyor 9 and in the receiving hopper. When the amount of water accumulated on the horizontal belt conveyor 9 and in the receiving hopper reaches a certain level, the water needs to be cleaned up before the inclined belt conveyor 1 can be run.

[0072] Both the detection module and the drive component 5 are electrically connected to the control module. The control module can control the action of the drive component 5 based on the amount of water accumulated on the horizontal belt conveyor 9 and / or in the receiving hopper. When the amount of water accumulated in the horizontal belt conveyor 9 and the receiving hopper reaches a certain level, the control module controls the drive component 5 to rotate, thereby switching the sealing mechanism to the second state and draining the water from the horizontal belt conveyor 9 and the receiving hopper.

[0073] During the drainage process, the detection module continues to monitor the amount of water on the horizontal belt conveyor 9 and in the receiving hopper in real time. Once the water on the horizontal belt conveyor 9 and in the receiving hopper are cleared, the control module controls the drive component 5 to rotate in the opposite direction, causing the sealing mechanism to switch to the first state and seal the first opening 11. After this, the inclined belt conveyor 1 can be operated to transport materials.

[0074] With this setup, the drainage process can be automated through the control and detection modules.

[0075] In this embodiment, the detection module includes a vision camera 8, which can capture and analyze images and videos. The vision camera 8 is used to obtain image information on the horizontal belt conveyor 9 and image information inside the receiving hopper. By analyzing the image information, the amount of water accumulated on the horizontal belt conveyor 9 and inside the receiving hopper can be determined.

[0076] In some embodiments, the control module also controls the actuation of the drive component 5 based on the amount of water accumulated on the horizontal belt conveyor 9 and the amount of water accumulated in the receiving hopper, thereby controlling the opening angle of the first sealing plate 4. When the amount of water accumulated on the horizontal belt conveyor 9 and the amount of water accumulated in the receiving hopper are large, the first sealing plate 4 is controlled to open at a larger angle; when the amount of water accumulated on the horizontal belt conveyor 9 and the amount of water accumulated in the receiving hopper are small, the first sealing plate 4 is controlled to open at a smaller angle.

[0077] On the other hand, embodiments of the present invention also provide a conveying system, including a horizontal belt conveyor 9, an inclined belt conveyor 1, and a receiving device provided in any of the above embodiments. The receiving device is disposed below the discharge end of the horizontal belt conveyor 9 and above the loading end of the inclined belt conveyor 1. The receiving device in the above embodiments can easily clean up water accumulated on the horizontal belt conveyor 9; therefore, the conveying system in this embodiment has the advantage of easy maintenance. The derivation process of the beneficial effects of the conveying system in the embodiments of the present invention is largely similar to the derivation process of the beneficial effects of the receiving device described above, and therefore will not be repeated here.

[0078] In another aspect, embodiments of the present invention also provide a mixing plant, including the receiving device or conveying system provided in any of the above embodiments. It possesses all the advantages of the aforementioned receiving device or conveying system, which will not be repeated here. The derivation process of the beneficial effects of the mixing plant in the embodiments of the present invention is largely similar to the derivation process of the beneficial effects of the aforementioned receiving device or conveying system, and therefore will not be repeated here.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
