Abstract

This invention discloses a rigid, follow-up, openable dustproof device. Through the coordinated operation of the follow-up drive mechanism and the rigid dustproof mechanism, the sealing unit corresponding to the current position can be opened continuously and in real time as the moving device moves, forming a dynamic receiving port and maintaining it in an open state. This meets the needs of the belt conveyor for dynamic material receiving or unloading throughout the entire conveying stroke. At the same time, the follow-up drive mechanism can also keep the other sealing units except the receiving port closed, thus ensuring the flexibility and effectiveness of material receiving and unloading operations. When the moving device moves away, the reset mechanism can drive the opened sealing units to flip and reset, restoring the sealing of the belt conveyor and improving the overall dynamic dustproof effect and operational reliability of the device.

Description

Technical Field

[0001] This invention relates to the field of belt conveyor technology, and more specifically to a rigid, follow-up, open-type dustproof device. Background Technology

[0002] Belt conveyors generate dust during the transport of bulk materials such as coal and sand aggregates. To avoid environmental pollution and material loss, enclosed dust covers are usually installed along the conveyor's corridor. For example, Chinese Patent No. CN 220392720U discloses a dust control device for belt conveyors, including a dust cover. The dust cover is composed of multiple dust-proof plates spliced ​​together. Each dust-proof plate has an arc-shaped structure, with ear plates at both ends that connect to the conveyor frame. The two ends of the dust-proof plates that meet are respectively provided with a connecting groove and a limiting plate. The limiting plate is lower than the dust-proof plate, and a stud is provided at the upper end of the limiting plate. When adjacent dust-proof plates meet, the limiting plate is located below the dust-proof plate, and the stud cooperates with the connecting groove. A clamping element and a nut are fitted on the stud. The dust cover is composed of multiple dust-proof plates that meet together. Each dust-proof plate is relatively independent but interconnected, allowing for individual disassembly and replacement of one dust-proof plate.

[0003] However, existing dust control devices typically only provide open spaces at the receiving and unloading ports of the belt conveyor throughout its entire conveying stroke, while the remaining areas are rigidly closed to prevent dust from being generated during material transport. But for mobile receiving conveyors, especially those that dynamically move to receive or unload materials throughout their entire conveying stroke, the open areas of existing dust control devices are fixed and cannot open and close with the moving receiving or unloading devices. This means that the dust cover must remain open during the movement of the receiving or unloading devices, and the dust cover cannot be restored to a seal immediately after the receiving or unloading devices are moved, causing dust to overflow severely from the open areas, making it difficult to meet the dynamic sealing and dust control requirements of mobile receiving conveyors.

[0004] Therefore, providing a dustproof device that can open along with a moving receiving or unloading device and can be reset and sealed to achieve effective dust prevention and moving receiving and unloading has become an urgent problem to be solved in this field. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this invention is to provide a rigid, follow-up opening dustproof device that can open along the way and then reset and seal, ensuring effective dust prevention and moving material receiving and unloading.

[0006] To achieve the above objectives, the present invention provides a rigid following open dustproof device that works in conjunction with a belt conveyor and a moving device. The moving device is used to receive or unload materials and can move on the belt conveyor. It includes a following drive mechanism and a rigid dustproof mechanism. The rigid dustproof mechanism is set on both sides of the belt conveyor through a reset mechanism, which can close the belt conveyor. The rigid dustproof mechanism has a number of continuously distributed and independently movable sealing units. The accompanying drive mechanism is mounted on the mobile device and can move synchronously with the mobile device. During the movement, it cooperates with the rigid dustproof mechanism to continuously drive the sealing unit corresponding to the current position of the mobile device to switch from the closed state to the open state, so as to form a receiving port corresponding to the current position of the mobile device and maintain the open state of the receiving port. It can also keep other sealing units except the area corresponding to the receiving port closed. The reset mechanism can drive the sealing unit to flip and reset.

[0007] Furthermore, the rigid dustproof mechanism includes fixed supports respectively disposed on both sides of the belt conveyor, and two sets of sealing units are symmetrically hinged to the fixed supports on the corresponding sides.

[0008] Furthermore, the sealing unit includes a rigid sealing sheet and a flexible folded fabric, wherein the flexible folded fabric connects two adjacent rigid sealing sheets.

[0009] Furthermore, the ends of the two symmetrically distributed sealing units are respectively provided with sealing overlap members.

[0010] Furthermore, the rigid dustproof mechanism also includes a dustproof curtain disposed at the bottom of the fixed bracket.

[0011] Furthermore, the reset mechanism includes a torsion spring disposed at the hinge point between the sealing unit and the fixed bracket.

[0012] Furthermore, the accompanying drive mechanism includes an open plowshare and a retaining plowshare, wherein the open plowshare is disposed at both ends of the moving device, and the retaining plowshare is disposed between the two sets of open plowshares.

[0013] Furthermore, two sets of open plowshares are symmetrically arranged at both ends of the mobile device, with the mobile device as the center.

[0014] Furthermore, the end of the open plowshare away from the plow body forms an inlet end, and the end that cooperates with the plow body forms a lifting end. Along the extension direction of the open plowshare, the height from the lifting end to the inlet end gradually decreases, and a smooth transition is achieved through a rounded transition surface.

[0015] Furthermore, the two sides of the open plowshare gradually become rounded and concave from the lifting end to the guiding end along the extension direction of the open plowshare, so that the two sides of the open plowshare form arc-shaped sides.

[0016] The rigid, follow-up, openable dustproof device provided by this invention, through the coordinated operation of the follow-up drive mechanism and the rigid dustproof mechanism, can continuously and in real time open the sealing unit corresponding to the current position as the moving device moves, forming a dynamic receiving port and maintaining it in an open state. This meets the needs of the belt conveyor for dynamic material receiving or unloading throughout the entire conveying stroke. At the same time, the follow-up drive mechanism can also keep the other sealing units except the receiving port closed, to meet the flexibility of material receiving and unloading operations and the effectiveness of dust prevention. When the moving device moves away, the reset mechanism can drive the opened sealing unit to flip and reset, restoring the covering seal to the belt conveyor, thereby improving the overall dynamic dustproof effect and operational reliability of the device.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0021] See Figures 1 to 3 The image shows an example of a rigid, flexible, openable dustproof device provided by the present invention.

[0022] As shown in the figure, the rigid, flexible, openable dustproof device in this example works in conjunction with the belt conveyor 1 and the moving device 2. The moving device 2 is used to receive or unload materials and can move on the belt conveyor 1. It mainly includes a following drive mechanism 3 and a rigid dustproof mechanism 4.

[0023] The rigid dustproof mechanism 4 is set on both sides of the belt conveyor 1 through the reset mechanism 5, which can close the belt conveyor 1. The rigid dustproof mechanism 4 has a number of continuously distributed and independently movable sealing units 41. The following drive mechanism 3 is set on the moving device 2 and can move synchronously with the moving device 2. During the movement, it cooperates with the rigid dustproof mechanism 4 to continuously drive the sealing unit 41 corresponding to the current position of the moving device 2 to switch from the closed state to the open state, so as to form the receiving port corresponding to the current position of the moving device 2 and maintain the open state of the receiving port. It can also keep other sealing units 41 except the area corresponding to the receiving port closed. The reset mechanism 5 can drive the sealing unit 41 to flip and reset, so as to realize the following opening and reset sealing of this device, ensuring effective dust prevention and moving receiving and unloading.

[0024] Combination Figure 2 and Figure 3 The rigid dustproof mechanism 4 includes a fixed bracket 42, which is respectively set on both sides of the belt conveyor 1 and extends to the inside of the belt conveyor 1 to support the sealing unit 41. The two sets of sealing units 41 are symmetrically distributed and hinged to the fixed bracket 42 on the corresponding side through the reset mechanism 5, so that the two sets of sealing units 41 can be connected and cooperate with each other to cover and enclose the belt conveyor 1.

[0025] Combination Figure 4 Furthermore, the ends of the two symmetrically distributed sealing units 41 are respectively provided with sealing overlap members 43, so that when the two sets of sealing units 41 are connected to each other, the sealing overlap members 43 can overlap each other, sealing the gap at the connection of the two sets of sealing units 41 and improving the dustproof effect.

[0026] The rigid dustproof mechanism 4 also includes a dustproof curtain 44, which is respectively installed at the bottom of the fixed brackets 42 on both sides to close the side ends of the belt conveyor 1, thereby cooperating with the sealing unit 41 to achieve full enclosure of the belt conveyor 1 and improve the dustproof effect.

[0027] Furthermore, several sealing units 41 in each group of sealing units 41 on one side are continuously distributed and can move independently to realize the step-by-step opening and closing of the rigid dustproof mechanism 4.

[0028] Combination Figure 5 Specifically, each sealing unit 41 includes a rigid sealing plate 411 and a flexible folded cloth 412. The rigid sealing plate 411 is hinged to the fixed bracket 42 through the reset mechanism 5. The flexible folded cloth 412 is disposed on the side end of the rigid sealing plate 411 and connects the rigid sealing plates 411 in two adjacent sealing units 41.

[0029] Preferably, the reset mechanism 5 is composed of a torsion spring.

[0030] Combination Figure 3 and Figure 5 Based on the above structure, the rigid sealing plate 411 can rotate away from the fixed bracket 42 through the reset mechanism 5 under the action of external force, so as to open the corresponding sealing unit 41 and form a receiving port in the area corresponding to the sealing unit 41. At the same time, the rigid sealing plate 411 will drive the flexible folding cloth 412 to unfold synchronously, and drive the rigid sealing plate 411 of the adjacent sealing unit 41 to rotate synchronously through the flexible folding cloth 412, so as to realize the step-by-step opening of the rigid dustproof mechanism 4.

[0031] Meanwhile, when the external force disappears, the reset mechanism 5 can drive the rigid sealing plate 411 to rotate towards the fixed bracket 42 based on its own elastic force, until it is mounted on the fixed bracket 42, so that the corresponding sealing unit 41 is reset and closed, and the receiving port corresponding to the area of ​​the sealing unit 41 is closed. At the same time, the rigid sealing plate 411 will drive the flexible folding cloth 412 to fold synchronously, and through the flexible folding cloth 412, drive the rigid sealing plate 411 of the adjacent sealing unit 41 to rotate synchronously, so that the flexible folding cloth 412 is folded between the two adjacent rigid sealing plates 411, so as to realize the step-by-step closure of the rigid dustproof mechanism 4.

[0032] like Figure 2 Furthermore, when the sealing unit 41 is closed, the rigid sealing plate 411 is mounted on the fixed bracket 42, and the fixed bracket 42 limits the rotation of the rigid sealing plate 411 to ensure that the rigid sealing plate 411 will not fall into the belt conveyor 1 and affect the normal conveying of materials.

[0033] The rigid dustproof mechanism 4 thus formed, through the coordinated cooperation of several sealing units 41, enables several discontinuously distributed rigid sealing thin plates 411 to be connected by flexible folded cloth 412 to achieve continuous distribution and independent movement, so as to realize the step-by-step opening and closing of the rigid dustproof mechanism 4.

[0034] Combination Figure 1In conjunction with this, the accompanying drive mechanism 3 is mounted on the mobile device 2 and can move synchronously with the mobile device 2. During the movement, it cooperates with the rigid dustproof mechanism 4 to continuously drive the sealing unit 41 corresponding to the current position of the mobile device 2 to switch from the closed state to the open state, so as to form the receiving port corresponding to the current position of the mobile device 2 and maintain the open state of the receiving port. This satisfies the need for the belt conveyor 1 to dynamically move to receive or unload materials within the entire conveying stroke range. In addition, the accompanying drive mechanism 3 can also maintain the closed state of other sealing units 41 except for the area corresponding to the receiving port, so as to meet the flexibility of receiving and unloading operations and the effectiveness of dust prevention.

[0035] Specifically, the following drive mechanism 3 includes an opening plowshare 31 and a holding plowshare 32. The opening plowshare 31 is located at both ends of the moving device 2, and the holding plowshare 32 is located between the two sets of opening plowshares 31. As a preferred arrangement, the two sets of opening plowshares 31 are symmetrically arranged at both ends of the moving device 2 with the moving device 2 as the center, so that no matter which direction the moving device 2 moves, the opening plowshare 31 at the front end along the moving direction of the moving device 2 can continuously push and open the sealing unit 41 corresponding to the current position step by step, and the holding plowshare 32 maintains the open state of the opened sealing unit 41. At the same time, the opening plowshare 31 at the rear end along the moving direction of the moving device 2 can close the sealing unit 41 behind the receiving port step by step, thereby forming a following dynamic receiving port and keeping the receiving port of the moving device 2 at the current position in an open state.

[0036] Furthermore, the sealing units 41 other than the area corresponding to the receiving port are not pushed by the opening plow 31 of the accompanying drive mechanism 3, and always maintain the initial closed state.

[0037] Combining 6 and Figure 7 Furthermore, the plowshare 31 and the plow body 32 are preferably configured as an integrated structure to ensure the structural stability of the follow-up drive mechanism 3, as well as the smooth opening and stable maintenance of the dynamic feed inlet.

[0038] The end of the open plowshare 31 away from the plow body 32 forms an inlet end 311, and the end that cooperates with the plow body 32 forms a lifting end 312. Along the extension direction of the open plowshare 31, the height from the lifting end 312 to the inlet end 311 gradually decreases and is smoothly transitioned through a smooth transition surface 313, so that the inlet end 311 can always be distributed below the sealing unit 41, and the inlet end 311 gradually and smoothly transitions to the lifting end 313 through the transition surface 313, and then transitions from the lifting end 313 to the plow body 32.

[0039] At the same time, the two sides of the plow head 31 are opened, and the plow head 31 is gradually rounded and concave from the lifting end 312 to the inlet end 311 along the extension direction of the plow head 31, so that the two sides of the plow head 31 form arc-shaped sides 314, and the plow head 31 is configured into a smooth triangular plow shape.

[0040] Furthermore, the plow body 32 is formed by the lifting end 312 extending horizontally along the moving direction of the moving device 2, so that the overall width and height of the plow body 32 are consistent with the lifting end 313, and the middle area of ​​the plow body 32 is a through hollow cavity 321 to cooperate with the moving device 2 to form a receiving port, so as to facilitate the conveyor belt to receive materials.

[0041] Based on the above structure, as the moving device 2 moves, the opening plowshare 31 at the front end along the moving direction can open the sealing unit 41 step by step. The inlet end 31 of the opening plowshare 31 is placed below the sealing unit 41. As the moving device 2 continues to move, the sealing unit 41 above the inlet end 31 gradually transitions to the transition surface 313 and is pushed up step by step by the transition surface 313. At the same time, the arc-shaped side 314 symmetrically lifts the sealing unit 41 to both sides of the opening plowshare 31, so that the sealing unit 41 in the corresponding area of ​​the moving device 2 is pushed up step by step and smoothly transitions to the lifting end 312, thereby completing the opening of all sealing units 41 at the current position.

[0042] When the sealing unit 41 reaches the lifting end 312, it smoothly transitions to the holding plow body 32. The holding plow body 32 can symmetrically support and limit the sealing units 41 on both sides of the holding plow body 32, keeping the sealing unit 41 in a stable open state. At this time, the hollow cavity 321 area in the middle of the holding plow body 32 is the continuous receiving port, which meets the needs of moving to receive or unload materials.

[0043] As the moving device 2 continues to move forward, the opening plow 31 at the rear end along the moving direction can gradually close the sealing unit 41 behind the receiving port. Specifically, the sealing unit 41 at the rear end of the receiving port begins to fall downward under the action of gravity and the reset device 5, and smoothly slides from the lifting end 312 to the inlet end 311 along the transition surface 313 of the rear opening plow 31. Under the guidance of the smooth transition surface 313 and the arc-shaped side 314, it finally detaches from the inlet end 311 and returns to the initial closed state, thereby realizing the gradual and smooth closing of the sealing unit 41.

[0044] The accompanying drive mechanism 3, in coordination with the rigid dustproof mechanism 4, can open the sealing unit 41 corresponding to the current position in real time and continuously as the moving device 2 moves, forming a dynamic receiving port and maintaining it in an open state, thereby meeting the needs of the belt conveyor 1 to dynamically move and receive or unload materials within the entire conveying stroke range; at the same time, the accompanying drive mechanism 3 can also keep the other sealing units 41 except for the receiving port closed, so as to meet the flexibility of receiving and unloading operations and the effectiveness of dust prevention.

[0045] When the moving device 2 moves away from its current position, the reset mechanism 5 can use its own elastic force to drive the opened sealing unit 41 to flip and reset, restoring the covering seal on the belt conveyor 1, thereby improving the overall dynamic dustproof effect and operational reliability of the device.
