Description

Technical Field

[0001] This application relates to the field of mechanical design and manufacturing technology, and in particular to a belt conveyor trough device. Background Technology

[0002] A trestle bridge is usually installed between the air-supported coal shed and the transfer building. The trestle bridge contains a conveyor belt and a material guide chute. One end of the material guide chute is inside the coal shed, and the other end is outside. Because the pressure difference between the air-supported coal shed and the outside is 450Pa, there is serious air leakage from inside the coal shed. This increases the difficulty of winter anti-freezing and anti-condensation work and daily dust control. In particular, the cold wind blows out in the severe winter, causing the temperature inside the transfer building to drop, and the heating system to freeze and crack frequently. During production, air leakage causes dust to drift, and the dust concentration on site exceeds the standard. At present, cotton quilts are used to seal the air outlet of the material guide chute to alleviate the problem. However, the cotton quilts need to be retracted when the conveyor belt is running, and then resealed when the belt stops, which increases the workload of the operators. Moreover, if the sealing is not tight or is forgotten, the temperature inside the transfer building will drop, causing the heating pipes and fire pipes inside the transfer building to freeze and crack. Utility Model Content

[0003] The purpose of this application is to overcome the above-mentioned problems and provide a belt conveyor chute device.

[0004] The technical solution of this application provides a belt conveyor trough device, including a trough with a discharge port, a conveyor belt mounted below the trough for transporting materials away, a flip-over baffle for covering the discharge port, a flipping mechanism for controlling the opening and closing of the flip-over baffle, and a control unit for controlling the operation of electrical components.

[0005] The flipping mechanism is located above the discharge port and is electrically connected to the control unit;

[0006] The flip-over wind deflector includes a wind deflector body connected to the flipping mechanism and a flexible baffle connected to the lower end of the wind deflector body and adapted to the contour of the conveyor belt.

[0007] When the flip-up baffle is in the closed state, the main body of the baffle covers the discharge port, the flexible baffle extends downward, and the lower end of the flexible baffle rests on the conveyor belt.

[0008] Furthermore, the wind deflector body includes an upper wind deflector, a pivot connector, and a lower wind deflector connected in sequence;

[0009] The flexible baffle is connected to the lower wind deflector.

[0010] Furthermore, the pivoting connector is a one-way flip hinge;

[0011] The lower baffle is connected to the one-way flip hinge and can flip forward relative to the discharge port.

[0012] Furthermore, the flexible baffle is connected to the lower end of the lower wind deflector by a pressure strip.

[0013] Furthermore, the flipping mechanism includes a rotating shaft pivotally mounted above the discharge port and a drive module for driving the rotating shaft to rotate, the drive module being electrically connected to the control unit;

[0014] The upper end of the wind deflector body is fixedly connected to the rotating shaft.

[0015] Furthermore, two mounting brackets are provided on the side wall of the guide trough facing the discharge port;

[0016] One end of the rotating shaft is rotatably mounted in one of the mounting brackets, and the other end of the rotating shaft rotatably passes through the other mounting bracket and is connected to the output of the drive module.

[0017] Furthermore, the bearing surface of the conveyor belt forms a groove, which extends along the conveying direction of the conveyor belt;

[0018] When the flip-up wind deflector is in the closed state, the flexible baffle extends into the groove formed by the conveyor belt.

[0019] Furthermore, the conveyor belt of the transport belt is signal-connected to the control unit.

[0020] Furthermore, a sealing strip is provided at the discharge port;

[0021] When the flip-up wind deflector is in the closed state, the sealing strip is in contact with the edge of the wind deflector body.

[0022] Furthermore, a wear-resistant layer is provided on the side of the flip-up baffle facing the discharge port.

[0023] The above technical solution has the following beneficial effects:

[0024] The conveyor belt trolley material guide device of this application includes a material guide trough with a discharge port, a conveyor belt mounted below the material guide trough, a tilting baffle for covering the discharge port, a tilting mechanism for controlling the opening and closing of the tilting baffle, and a control unit for controlling electrical components. The tilting mechanism is located above the discharge port and is electrically connected to the control unit. By setting a baffle body connected to the tilting mechanism at the discharge port and a flexible baffle connected to the lower end of the baffle and resting on the conveyor belt, the discharge port of the material guide trough is blocked, effectively isolating the exchange of internal and external airflow. This ensures that the indoor temperature is effectively protected in winter and also helps to advance dust control work. Furthermore, it can automatically block the material guide trough when there is no material transport, reducing the workload of operators and achieving a dual improvement in production safety and environmental management.

[0038] The specific embodiments of this application will be further described below with reference to the accompanying drawings.

[0039] It is readily understood that, based on the technical solution of this application, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of this application. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this application and should not be considered as the entirety of this application or as limitations or restrictions on the technical solution of the application.

[0040] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meanings of the above in this application according to the specific circumstances.

[0042] like Figures 1-6 As shown, a conveyor belt trolley guide trough 1 device in one embodiment of this application includes a guide trough 1 with a discharge port 11, a conveyor belt 2 assembled below the guide trough 1 for transporting materials, a flipping baffle 3 for covering the discharge port 11, a flipping mechanism 4 for controlling the opening and closing of the flipping baffle 3, and a control unit 5 for controlling the operation of electrical components.

[0043] The flipping mechanism 4 is located above the discharge port 11 and is electrically connected to the control unit 5.

[0044] The flip-over wind deflector 3 includes a wind deflector body 31 connected to the flip-over mechanism 4 and a flexible baffle 32 connected to the lower end of the wind deflector body 31 and adapted to the contour of the conveyor belt 2.

[0045] When the flip-up baffle 3 is in the closed state, the baffle body 31 covers the discharge port 11, the flexible baffle 32 extends downward, and the lower end of the flexible baffle 32 falls on the conveyor belt 2.

[0046] In this embodiment, the device includes a material guide trough 1, a conveyor belt 2, a tilting baffle 3, a tilting mechanism 4, and a control unit 5. The material guide trough 1 has a discharge port 11. The conveyor belt 2 is mounted below the material guide trough 1 and is used to transport materials away. The tilting baffle 3 is set above the discharge port 11 to cover the discharge port 11. The tilting mechanism 4 is used to control the opening and closing of the tilting baffle 3. The control unit 5 is electrically connected to the tilting baffle 3 and is used to control the operation of electrical components.

[0047] The flip-over wind deflector 3 includes a wind deflector body 31 and a flexible baffle 32. The wind deflector body 31 is connected to the flipping mechanism 4, and the flexible baffle 32 is connected to the lower end of the wind deflector body 31 and is adapted to the contour of the conveyor belt 2. When the flip-over wind deflector 3 is in the closed state, the wind deflector body 31 covers the discharge port 11, and the flexible baffle 32 extends downward. The lower end of the flexible baffle 32 rests on the conveyor belt 2, which can close the discharge port 11 and effectively isolate the exchange of internal and external airflow. The flip-over wind deflector 3 can be adjusted by the control unit 5, which eliminates the need for technicians to manually adjust the flip-over wind deflector 3 and reduces the workload of technicians.

[0048] The lower end of the flexible baffle 32 is adapted to the contour of the conveyor belt 2, and when the flip baffle 3 is in the closed state, it falls on the conveyor belt 2 to seal the discharge port 11. It maintains continuous elastic contact with the surface of the conveyor belt 2. Under complex working conditions such as belt vibration, offset or wavy undulation, it autonomously compensates for the small gaps caused by mechanical deformation, effectively overcoming the problem of sealing failure caused by the dynamic displacement of the conveyor belt 2.

[0049] like Figure 1 , Figures 3-5 As shown, in another embodiment, the wind deflector body 31 includes an upper wind deflector 311, a pivot connector 312, and a lower wind deflector 313 connected in sequence.

[0050] The flexible baffle 32 is connected to the lower wind deflector 313.

[0051] In this embodiment, the main body 31 of the wind deflector includes an upper wind deflector 311, a pivot connector 312, and a lower wind deflector 313 connected in sequence. The upper end of the upper wind deflector 311 is connected to the flipping mechanism 4, and the lower end of the upper wind deflector 311 is connected to the upper end of the lower wind deflector 313. A pivot connector 312 is provided between the upper wind deflector 311 and the lower wind deflector 313, so that the lower wind deflector 313 can be flipped relative to the upper wind deflector 311 to a certain extent. When the flipping wind deflector 3 is turned from open to closed, if the conveyor belt 2 is still transporting coal, the flexible baffle 32 will first contact the coal and deform to a certain extent. If it continues to be closed, the lower wind deflector 313 will contact the coal. At this time, since the lower wind deflector 313 can be flipped relative to the upper wind deflector 311 to a certain extent, the situation of the coal getting stuck on the flipping wind deflector 3 is effectively avoided, preventing the device from deforming and causing damage, and enhancing the life and working safety of the device.

[0052] like Figure 1 , Figures 3-5 As shown, in one preferred embodiment, the pivoting connector 312 is a one-way flip hinge.

[0053] The lower baffle plate 313 is connected to a one-way flip hinge and can flip forward relative to the discharge port 11.

[0054] In this preferred embodiment, the pivot connector 312 is a one-way flip hinge, or a one-way flip hinge. The upper end of the lower baffle plate 313 is connected to the one-way flip hinge, and the lower end of the upper baffle plate 311 is connected to the one-way flip hinge. Therefore, the lower baffle plate 313 can flip forward relative to the upper baffle plate 311, that is, flip forward relative to the discharge port 11. This is because the direction of coal transportation is that the discharge port 11 is transported towards the conveyor belt 2. When the flip baffle plate 3 changes from open to closed, if the conveyor belt 2 is still transporting coal, the lower baffle plate 313 will come into contact with the coal. At this time, the lower baffle plate 313 can flip relative to the discharge port 11, and the direction of flipping is the same as the direction of coal transportation. Therefore, when the flip baffle plate 3 is closed, the lower baffle plate 313 will not be damaged due to contact with the coal, thus extending the service life of the device and significantly reducing the maintenance cost and downtime cost for technicians.

[0055] like Figure 1 , Figures 3-5 As shown, in another embodiment, the flexible baffle 32 is connected to the lower end of the lower wind deflector 313 by a pressure strip 33.

[0056] In this embodiment, the flexible baffle 32 is connected to the lower end of the lower wind deflector 313 by a pressure strip 33. The pressure strip 33 can be a detachable bolt or a snap-fit ​​connection interface to achieve quick decoupling between the flexible baffle 32 and the lower wind deflector 313. When the flexible baffle 32 needs to be repaired or replaced due to long-term wear, it is not necessary to completely remove and flip the wind deflector 313. Only the pressure strip 33 needs to be removed to independently remove the flexible baffle 32. Compared with the traditional welding fixing method, the downtime for maintenance is significantly shortened, and the risk of deformation of the connection hole caused by repeated disassembly and assembly of rigid components is also avoided.

[0057] like Figure 1 , Figures 3-6 As shown, in one embodiment, the flipping mechanism 4 includes a rotating shaft 41 pivotally mounted above the discharge port 11 and a drive module 42 for driving the rotating shaft 41 to rotate, the drive module 42 being electrically connected to the control unit 5.

[0058] The upper end of the wind deflector 3 body is fixedly connected to the rotating shaft 41.

[0059] In this embodiment, the flipping mechanism 4 includes a rotating shaft 41 pivotally mounted above the discharge port 11 and a drive module 42 for driving the rotating shaft 41 to rotate. The drive module 42 is electrically connected to the control unit 5, and the upper end of the baffle plate 3 body is fixedly connected to the rotating shaft 41. That is, the upper end of the upper baffle plate 311 is fixedly connected to the rotating shaft 41. The drive module 42 only needs to apply a small torque to realize the rapid flipping of the flipping baffle plate 3. At the same time, the rotating shaft 41 is located above the discharge port 11 and basically does not contact the coal at the discharge port 11, which avoids dust from entering the bearing and causing jamming, and extends the service life of the flipping mechanism 4.

[0060] like Figure 1 , Figure 3 As shown, in one embodiment, two mounting brackets 43 are provided on the side wall of the guide trough 1 facing the discharge port 11.

[0061] One end of the rotating shaft 41 is rotatably mounted in one of the mounting brackets 43, and the other end of the rotating shaft 41 is rotatably passed through another mounting bracket 43 and connected to the output end of the drive module 42.

[0062] In this embodiment, two mounting brackets 43 are also provided on the side wall of the guide trough 1 facing the discharge port 11. One end of the rotating shaft 41 is rotatably installed in one of the mounting brackets 43, and the other end is rotatably passed through the other mounting bracket 43 and connected to the output end of the drive module 42. Compared with the single-sided cantilever shaft structure, it effectively suppresses the vibration generated by high-frequency opening and closing and increases the service life of the flipping mechanism 4.

[0063] The mounting bracket 43 on the side with the drive module 42 can adopt a split flange design. After removing the cover plate, the drive module 42 can be taken out as a whole without damaging the main structure of the guide chute 1. This can reduce the maintenance time of the drive module 42 and avoid disassembling and assembling the entire flipping mechanism 4 during maintenance.

[0064] like Figures 1-3 As shown, in another embodiment, the bearing surface of the conveyor belt 2 forms a groove 21, which extends along the conveying direction of the conveyor belt 2.

[0065] When the flip-up wind deflector 3 is in the closed state, the flexible baffle 32 extends into the groove 21 formed by the conveyor belt 2.

[0066] In this embodiment, the bearing surface of the conveyor belt 2 forms a groove 21, which extends along the conveying direction of the conveyor belt 2. The flexible baffle 32 extends into the groove 21 formed by the conveyor belt 2. The curved surface of the groove 21 makes the conveyor belt 2 form a semi-closed loop channel. The flexible baffle 32 extends into the groove 21 and fills the gap of the groove 21, thereby improving the blocking rate of powder and airflow. Furthermore, the contour fit between the flexible baffle 32 and the groove 21 reduces the wear problem of traditional planar seals. Even if the vibration of the conveyor belt 2 causes the groove 21 to deform, the extensibility of the flexible baffle 32 can continue to fill and compensate the gap, increasing the service life of the conveyor belt 2 and the windproof performance when the flip-up wind deflector 3 is closed.

[0067] like Figure 6 As shown, in another embodiment, the conveyor belt 22 of the transport belt 2 is signal-connected to the control unit 5.

[0068] In this embodiment, the conveyor belt 22 of the conveyor belt 2 is connected to the control unit 5 by signal. That is, the opening signal and closing signal of the conveyor belt 2 will be transmitted to the control unit 5. After receiving the signal, the control unit 5 controls the opening / closing of the flip-up wind deflector 3 according to the opening signal / closing signal.

[0069] Specifically, when the conveyor belt 22 of the conveyor belt 2 is turned on, the control unit 5 receives the signal that the conveyor belt 22 is turned on and controls the tilting baffle 3 to open, so that the coal can enter the conveyor belt 2 from the discharge port 11 and be transported away. When the conveyor belt 22 of the conveyor belt 2 is turned off, the control unit 5 receives the signal that the conveyor belt 22 is turned off and controls the tilting baffle 3 to close. The automated control between the conveyor belt 22, the tilting baffle 3 and the control unit 5 reduces the workload of the operators and avoids various losses caused by forgetting to seal.

[0070] In another embodiment, a sealing strip is provided at the discharge port 11.

[0071] When the flip-up wind deflector 3 is in the closed state, the sealing strip is in contact with the edge of the wind deflector 3 body.

[0072] In this embodiment, a sealing strip is provided at the discharge port 11. When the flip-up baffle 3 is in the closed state, the sealing strip fits against the edge of the baffle 3 body to seal the gap between the baffle 3 body and the discharge port 11, effectively preventing coal from escaping from the edge, preventing the dust concentration on site from exceeding the standard, and enhancing the sealing performance to prevent air leakage from the coal shed.

[0073] In one embodiment, the side of the flip-up baffle 3 facing the discharge port 11 is provided with a wear-resistant layer.

[0074] In this embodiment, a wear-resistant layer is provided on the side of the flip-over baffle 3 facing the discharge port 11. Specifically, wear-resistant layers are provided on the side of the upper baffle 311 facing the discharge port 11, the side of the lower baffle 313 facing the discharge port 11, and the side of the flexible baffle 32 facing the discharge port 11. This enhances the wear resistance of the flip-over baffle 3, extends its service life, avoids surface damage and performance degradation caused by long-term use, ensures the stable operation of the device, and reduces maintenance costs.

[0075] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0076] The above description is merely the principle and preferred embodiment of this application. It should be noted that for those skilled in the art, implementation methods obtained by appropriately combining the technical solutions disclosed in different embodiments are also included within the technical scope of this invention. Based on the principle of this application, several other modifications can also be made, which should also be considered within the protection scope of this application.
