Description

Technical Field

[0001] The present invention belongs to the technical field of material transportation equipment, and particularly relates to a bidirectional conveying pipe belt conveyor. Background Art

[0002] The pipe belt conveyor is an important branch of the traditional belt conveyor. It is mainly to avoid the serious environmental pollution caused by dust and material scattering during the transportation of the traditional open belt conveyor, which prompts the industry to seek a closed solution. The pipe belt conveyor forms an "O"-shaped cylindrical structure by rolling up and closing both sides of the flat conveyor belt, thus can well solve the above problems.

[0003] With the development needs of modern industry, the technology of the pipe belt conveyor has developed rapidly. Because it not only has the initial advantages of being closed, environmentally friendly and non-spilling, but also has the characteristics of long-distance conveying, building on complex terrains, climbing large slopes at large angles, turning horizontally at small angles, and various layout forms combinations; it can also meet the requirements of low investment and short construction period. Therefore, the technical improvement of the pipe belt conveyor is the development direction of continuously conveying bulk materials in the future.

[0004] In the prior art, the pipe belt conveyor generally includes a feeding section, a discharging section and a middle conveying section. The conveyor belts connected end to end reciprocate between these three positions to convey materials from the feeding section to the discharging section. The feeding section includes: a feeding device for loading materials onto the conveyor belt; and a conveyor belt shape conversion device composed of 4-5 sets of conversion mechanisms arranged in sequence in the feeding section, which is used to convert the conveyor belt of the load-carrying section from a flat shape to a round pipe shape, and convert the conveyor belt of the empty-load return section from a round pipe shape to a flat shape; the discharging section includes: a driving device for providing operating power for the whole conveyor; a discharging device for discharging the materials on the conveyor belt to the material site; a tensioning device for adjusting the tension of the whole conveyor belt; and a conveyor belt shape conversion device, the structure of which is similar to that of the conversion structure in the feeding section, which is used to convert the conveyor belt of the load-carrying section from a round pipe shape to a flat shape, and convert the conveyor belt of the empty-load return section from a flat shape to a round pipe shape; the middle conveying section includes several sets of conveyor belt support frames for supporting the conveyor belts of the load-carrying section and the return section, and maintaining the round pipe shape of the conveyor belt to prevent material spillage.

[0005] Existing pipe-belt conveyors are all one-way conveyors, that is, the conveyor belt transports the carried materials from the receiving section to the unloading section (carrying section), and then returns to the receiving section (return section) empty from the unloading section along the carrying section (arranged below the carrying section) after passing through the reversing device, and repeats this cycle. In some cases, it is necessary to carry materials in the return section so that other materials can be transported back to the receiving section or other locations. However, due to the structural limitations of existing pipe-belt conveyors, the conveyor belt interface of the return section faces downward, and when carrying materials, it will be pressed open by the materials, causing material spillage; when there is a need to carry materials in the return section, a new pipe-belt conveyor can only be built, which undoubtedly increases transportation costs.

[0006] In addition, the conveyor belt support frame of the middle conveying section of the existing pipe belt conveyor usually adopts a hexagonal roller structure (such as Figure 1 As shown). It includes two upper and lower hexagonal roller groups (each roller group consists of 6 rollers arranged in a hexagon) and a roller group bracket. The upper hexagonal roller group is used to support the bearing section conveyor belt, and the lower hexagonal roller is used to support the return section conveyor belt. The conveyor belt support frame of this structure, because the rollers in contact with the conveyor belt are hexagonal rather than round tubes that match the conveyor belt, the interface of the conveyor belt cannot be well sealed, so it is easy to spill materials; and when supporting the conveyor belt, multiple rollers will inevitably be unevenly stressed, causing some of the rollers to be severely worn and rotated and stuck, which in turn causes the conveyor belt to be stuck, affecting the operation of the entire conveyor; in addition, the hexagonal roller structure is complex, and the conveyor conveying distance is as short as a few hundred meters and as long as tens of kilometers. It is usually necessary to set up a conveyor belt support frame every 0.5m to 1m, and it is necessary to build a corridor on the periphery to facilitate personnel maintenance and reduce contact with the external environment. Therefore, the cost is very high, and due to the complex structure, it is time-consuming and labor-intensive to repair or replace the rollers, affecting the transportation process of the materials.

[0007] In view of the above situation, a new type of pipe-belt conveyor is urgently needed, which, through structural optimization, can solve the problems that the existing pipe-belt conveyor cannot realize bidirectional material transportation, as well as the problems existing in the conveyor belt support frame in the middle conveying section.

[0008] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0070] There is no specific restriction on the sources of the raw materials and instruments used in the embodiments, and they can be purchased in the market or prepared according to the conventional methods well-known to those skilled in the art.

[0071] Please refer to Figures 1 to 12 the content shown below for a better understanding of the specific structure of the present invention. As Figure 2 shown, a two-way conveying pipe belt conveyor is characterized by comprising:

[0072] A receiving section 1, arranged at both ends of the conveyor, configured to adjust the tension of the conveyor belt 5, load the material 9 onto the conveyor belt 5, convert the conveyor belt 5 from a planar shape to a circular tube shape, and change the running direction of the conveyor belt 5;

[0073] A discharging section 2, arranged at both ends of the conveyor, configured to drive the conveyor belt 5 to run, dump the material 9 on the conveyor belt 5 to the material site, convert the conveyor belt 5 from a circular tube shape to a planar shape, and change the running direction of the conveyor belt 5;

[0076] And a double-sided conveying section 4, arranged in the middle of the conveyor, including 2 conveyor belts 5 running in both directions;

[0077] Both the single-sided conveying section 3 and the double-sided conveying section 4 include a number of sets of conveyor belt support frames 6 arranged in sequence along the conveyor;

[0078] As Figure 4 shown, the conveyor belt support frame 6 is configured to support the conveyor belt 5 and maintain the conveyor belt 5 in a circular tube shape, and includes:

[0079] The pipe belt idler 601 is arranged in the middle of the conveyor belt support frame 6 and is configured to support the conveyor belt 5 in the load-carrying section and maintain the circular pipe shape of the conveyor belt 5.

[0080] The pressure belt idler 602 is arranged above the pipe belt idler 601 and is configured to cooperate with the pipe belt idler 601 to maintain the circular pipe shape of the conveyor belt 5.

[0081] And the structural member 603 is a frame structure formed by connecting a number of rod-shaped components and is configured to support the pipe belt idler 601 and the pressure belt idler 602.

[0082] It should be noted that a number of conveyor belt support frames 6 are arranged along the conveyor belt 5. Due to the weak wrapping property of the conveyor belt support frame 6 in the prior art, it is unable to maintain the circular pipe shape of the conveyor belt 5 well. Therefore, usually a set of conveyor belt support frames 6 needs to be set every 0.5 m to 1 m; the conveyor belt support frame 6 provided by the present invention is provided with a pipe belt idler 601 and a pressure belt idler 602, which can be well matched with the circular pipe shape of the conveyor belt 5, so as to be able to firmly maintain the circular pipe shape of the conveyor belt 5. Therefore, the interval of the conveyor belt support frames 6 can be extended to 2 m to 2.5 m, saving a large amount of construction costs.

[0083] In specific implementation, the technical solution provided by the present invention is provided with a feeding section 1, a discharging section 2 and a single-side conveying section 3 at both ends of the conveyor, which can realize the two-way transportation of the pipe belt conveyor, solve the problem that the pipe belt conveyor in the prior art cannot perform two-way transportation, improve the production efficiency and save the transportation cost; this technical solution abandons the traditional hexagonal idler structure of the conveyor belt support frame 6 and adopts the structure of the cooperation between the pipe belt idler 601 and the pressure belt idler 602 to form a circular channel matching the circular pipe shape of the conveyor belt 5 in the single-side conveying section 3 and the double-side conveying section 4 of the conveyor respectively; effectively reduces the probability of easy material scattering, easy belt jamming and easy damage of the existing pipe belt conveyor, and has a simple structure, can increase the interval between the conveyor belt support frames 6, effectively reduce the construction cost and facilitate subsequent maintenance and replacement of accessories; the pipe belt idler 601 is provided to enable one idler to cooperate with the conveyor belts 5 on both the round-trip sides at the same time, which is convenient for installing an independent driving device 202 for each idler subsequently, and uses photovoltaic power supply to provide operating power for the whole pipe belt conveyor, effectively reducing energy consumption.

[0084] In the embodiment provided by the present invention, as Figure 3 shown, the feeding section 1 includes:

[0085] The tensioning device 101 is configured to adjust the tension of the conveyor belt 5;

[0086] The feeding section reversing device 102 is configured to change the running direction of the conveyor belt 5;

[0087] The feeding device 103 is configured to load the material 9 onto the conveyor belt 5;

[0088] and the shape conversion device of the conveyor belt 5 in the feeding section 1 is configured to convert the conveyor belt 5 from a planar shape to a circular tube shape;

[0089] The tensioning device 101, the feeding section reversing device 102, the feeding device 103, and the shape conversion device of the conveyor belt 5 in the feeding section 1 are arranged in sequence along the running direction of the conveyor belt 5.

[0090] The discharging section 2 includes:

[0091] The shape conversion device of the conveyor belt 5 in the discharging section 2 is configured to convert the conveyor belt 5 from a circular tube shape to a planar shape;

[0092] The discharging device 201 is configured to dump the material 9 on the conveyor belt 5 to the material site;

[0093] The driving device 202 is configured to drive the conveyor belt 5 to run;

[0094] and the discharging section reversing device 203 is configured to change the running direction of the conveyor belt 5;

[0095] The shape conversion device of the conveyor belt 5 in the discharging section 2, the discharging device 201, the driving device 202, and the discharging section reversing device 203 are arranged in sequence along the running direction of the conveyor belt 5.

[0096] It should be noted that the tensioning device 101 (preferably a vehicle type tensioning structure), the feeding device 103, the shape conversion device of the conveyor belt 5 in the feeding section 1, the shape conversion device of the conveyor belt 5 in the discharging section 2, the discharging device 201, and the driving device 202 are all preferably devices in the prior art, as long as they can achieve the corresponding functions, and there is no limitation here.

[0097] It should be noted that the feeding section reversing device 102 and the discharging section reversing device 203 have the same structure, both including a bracket 104 and a roller 105. Multiple sets or one set can be set according to actual needs; the bracket 104 is fixed on the ground or the conveyor support frame, and the roller 105 is supported on the bracket 104 through a bearing 609 and can rotate freely on the bracket 104; when the conveyor belt 5 is in a planar shape, bypassing the roller 105 can change the running direction by a corresponding angle. The specific value can be set according to actual needs, and just by setting another roller 105 and the bracket 104 at different positions, the angle can be changed; in the present invention, as Figure 3 shown in the structure, using 2 sets of feeding section reversing devices 102 can change the running direction of the conveyor belt 5 by 180°.

[0098] In specific implementation, a set of feeding section 1 and a set of discharging section 2 are respectively arranged at both ends of the conveyor, which can realize feeding and discharging of the conveyor belt 5 at both ends of the conveyor, and circularly transport two different materials 9 at both ends of the conveyor, thereby improving production efficiency and reducing transportation costs.

[0099] In one embodiment, as Figures 5 to 7 shown, the pipe belt idler 601 includes:

[0100] A first roller 6011, fixed on the structural member 603 through a support 604, and capable of rotating on the support 604;

[0101] A first arc-shaped shaping belt 6012, in a hub-shaped structure, sleeved on the first roller 6011, and the contact surface with the conveyor belt 5 is arc-shaped;

[0102] And a first support plate 6013, in a plate-shaped structure, arranged on both sides of the first arc-shaped shaping belt 6012, and configured to support the first arc-shaped shaping belt 6012 to maintain the arc shape of the contact surface between the first arc-shaped shaping belt 6012 and the conveyor belt 5;

[0104] The bushing 605 is connected to the first roller 6011 through a transmission key 606.

[0105] It should be noted that the structural member 603 is preferably built by fixedly connecting a plurality of steel pipe profiles to each other.

[0106] It should be noted that the first roller 6011 is made of metal material, preferably series steel material, fixed on the structural member 603 at both ends through the support 604, and supported on the support 604 through bearings 609.

[0107] It should be noted that the first arc-shaped shaping belt 6012 can be made of metal materials such as steel or aluminum alloy, or can also be made of non-metal materials such as PVC or fiberglass. The present invention preferably uses series steel materials, and the surface in contact with the conveyor belt 5 can be subjected to rubber coating or glue injection treatment to form a rubber coating layer 607 to improve wear resistance; the radian size of the first arc-shaped shaping belt 6012 can be customized according to the circular tube shape size of the actually used conveyor belt 5 to provide better wrapping property.

[0108] It should be noted that the first support plate 6013 can be made of the same material as the first arc shaping belt 6012. Since it has no contact with the conveyor belt 5, it does not need to be rubber-coated or injected with glue. The inner surface of the first support plate 6013 is fixedly connected to the outer side of the first arc shaping belt 6012, and is preferably fixed by riveting or welding. It can be made into a circular, square, polygonal or other symmetric plate-like structure. In the present invention, a circular plate-like structure is preferably used. The first support plate 6013 is fixed on both sides of the first arc shaping belt 6012, which can provide sufficient support force for the sides of the first arc shaping belt 6012 to maintain the arc shape of the first arc shaping belt 6012 and prevent deformation under the pressure of the material 9.

[0109] It should be noted that the bushing 605 connects and fixes the middle part of the first support plate 6013 and the first arc shaping belt 6012, and is preferably fixed by welding or riveting. The bushing 605 is sleeved on the first roller 6011, and the rotational torque is transmitted through the transmission key 606, and the axial positioning is performed at both ends of the bushing 605 through the positioning lock ring 608.

[0111] In the embodiment provided by the present invention, as Figure 8 shown, the pressure belt wheel 602 includes:

[0112] A second roller 6021, which is fixed on the structural member 603 through a support 604 and can rotate on the support 604;

[0113] A second arc shaping belt 6022, which is in a hub-shaped structure and is sleeved on the second roller 6021, and the contact surface with the conveyor belt 5 is arc-shaped;

[0115] The central parts of the second arc shaping belt 6022 and the second support plate 6023 are fixedly connected to the second roller 6021 through a bushing 605;

[0116] The bushing 605 is connected to the second roller 6021 through a transmission key 606.

[0117] It should be noted that the pinch roller 602 utilizes the arc grooves of the second arc shaping belt 6022 to cooperate with the arc grooves of the first arc shaping belt 6012 to form a circular channel with the same shape as the circular tube of the conveyor belt 5. Its function is to press the side or upper part of the circular tube-shaped conveyor belt 5 to prevent the joint of the conveyor belt 5 from opening and causing material spillage.

[0118] It should be noted that the second roller 6021 is made of metal material, preferably a series of steel materials. Both ends are fixed on the structural member 603 through the supports 604 and are supported on the supports 604 through the bearings 609.

[0119] It should be noted that the second arc shaping belt 6022 can be made of metal materials such as steel or aluminum alloy, or non-metal materials such as PVC or fiberglass. The present invention preferably uses a series of steel materials. The surface in contact with the conveyor belt 5 can be subjected to rubber coating or glue injection treatment to form a rubber coating layer 607 to improve wear resistance; the radian size of the second arc shaping belt 6022 can be customized according to the circular tube shape size of the actually used conveyor belt 5 to provide better wrapping property.

[0120] It should be noted that the second support plate 6023 can be made of the same material as the second arc shaping belt 6022. Since it has no contact with the conveyor belt 5, it does not need to be rubber-coated or glue-injected.

[0121] The inner surface of the second support plate 6023 is fixedly connected to the outer side of the second arc shaping belt 6022, preferably fixed by riveting or welding, and can be made into a circular, square, polygonal or other symmetric plate-shaped structure. The present invention preferably uses a circular plate-shaped structure.

[0122] The second support plate 6023 is fixed on both sides of the second arc shaping belt 6022, which can provide sufficient supporting force for the sides of the second arc shaping belt 6022 to maintain the arc shape of the second arc shaping belt 6022 and prevent deformation under the action of the material 9 pressure.

[0123] It should be noted that the bushing 605 connects and fixes the middle part of the second support plate 6023 and the second arc shaping belt 6022, preferably fixed by welding or riveting.

[0124] The bushing 605 is sleeved on the second roller 6021, transmits the rotational torque through the transmission key 606, and is axially positioned at both ends of the bushing 605 through the positioning lock ring 608.

[0125] It should be noted that in the prior art, for the idler support 801 with the hexagonal idler group 8 structure, in the part of the conveyor belt 5 that bears the material 9, the idlers 802 are unevenly stressed under the action of the gravity of the material 9. For example, when the conveyor belt 5 runs on a horizontal straight section, the idler 802 at the bottom of the load-bearing section in the hexagonal idler structure is under the greatest pressure and is most likely to be worn. Only by increasing its own structural size can the wear be reduced, but this will cause asymmetry in the overall structure, or increasing the size of all idlers 802 will increase the cost. However, for the conveyor belt support frame 6 provided by the present invention, the pressure of the material 9 is concentrated on the pipe belt idler 601, especially the first roller 6011 is under the greatest stress. Therefore, only by increasing the structural size of the pipe belt idler 601 can the wear of the components be reduced, thereby reducing the production losses caused by tape jams, shutdown for maintenance, component replacement, etc. due to component damage.

[0126] In specific implementation, the pipe belt idler 601 and the pressure belt roller 602 cooperate to form a closed circular channel that matches the circular tube shape of the conveyor belt 5, which can better maintain the circular tube shape of the conveyor belt 5 and effectively prevent the occurrence of material spillage; by utilizing its own unique structural advantages, the risk of tape jams and component damage caused by uneven stress is reduced, which is beneficial to the safe, stable and smooth progress of production.

[0127] In one embodiment, as Figure 9 shown, the conveyor belt support frame 6 arranged in the single-sided conveying section 3 is provided with 1 horizontally arranged pipe belt idler 601, and a pressure belt roller 602 arranged on the side of the pipe belt idler 601 close to the center of the turning arc of the conveyor belt 5; the second arc shaping belt 6022 and the first arc shaping belt 6012 form a circular channel with the same shape as the conveyor belt 5.

[0128] It should be noted that the single-sided conveying section 3 is arranged at both ends of the conveyor, and is a detour section provided for the conveyor belt 5 to achieve two-way transportation, that is, the conveyor belt 5 uses the single-sided conveying section 3 to turn around. Therefore, there is only one conveyor belt 5 in the single-sided conveying section 3, and the entire single-sided conveying section 3 is in an arc shape, and the arc radius cannot be too small, otherwise it will cause the conveyor belt 5 to be damaged due to excessive tension. The turning radius of the single-sided conveying section 3 of the present invention is set to 10-15 times the diameter of the circular tube of the conveyor belt 5; in the prior art, the minimum turning radius when the conveyor belt 5 needs to turn is usually 15-20 times the diameter of the circular tube of the conveyor belt 5, which increases the floor area and construction cost.

[0129] It should be noted that since the single-sided conveying section 3 has a certain curvature, the forces exerted by the tensioning device 101 on the inner and outer sides of the conveyor belt 5 at this position during operation are different. The tension force on the outer side due to the increased length is greater than that on the inner side, and the pressure of the material 9 under the outward centrifugal force will also cause the force on the outer side of the conveyor belt 5 to increase. This situation becomes more obvious as the curvature increases. In the prior art, when the conveyor belt 5 turns with a curvature, the forces on the inner and outer sides are uneven, which will cause the outer idler 802 to be subjected to increased force and is prone to wear. Moreover, the increased force on the outer side of the conveyor belt 5 will pull open the joint and cause material scattering. Therefore, a larger turning radius is required. In the technical solution provided by the present invention, a pipe belt idler 601 arranged horizontally is provided in the single-sided conveying section 3, and the pressure belt wheel 602 is arranged on the inner side of the pipe belt idler 601 close to the center of the curvature. When the force on the outer side of the conveyor belt 5 increases, it is all borne by the first roller 6011. Structurally, it can fully withstand the increased force, and can keep the circular tube shape of the conveyor belt 5 unchanged and the interface will not be pulled open, thereby preventing situations such as material scattering, belt jamming, and wear, and can achieve a smaller turning radius, thus reducing the floor area and construction cost.

[0130] In specific implementation, the single-sided conveying section 3 adopts the above structure, which can reduce the influence of the outward force on the conveyor belt 5 and further ensure the smooth progress of production and transportation.

[0131] In the embodiment provided by the present invention, as Figure 10 shown, the double-sided conveying section 4 includes double-sided arc sections; the conveyor belt support frame 6 arranged on the double-sided arc sections is provided with a pipe belt idler 601 arranged horizontally, and pressure belt wheels 602 symmetrically arranged on the left and right sides of the pipe belt idler 601; two second arc shaping belts 6022 respectively form a circular channel with the same shape as the conveyor belt 5 with the first arc shaping belt 6012.

[0132] It should be noted that the double-sided conveying section 4 is the overlapping part of the reciprocating conveyor belt 5, and there are two reciprocating conveyor belts 5. The more the overlapping part, the lower the construction cost (the reciprocating conveyor belts 5 can share a conveyor belt support frame 6); the double-sided conveying section 4 is usually built according to the terrain. The double-sided conveying section 4 in a flat and unobstructed area is a double-sided straight section; when encountering obstacles such as buildings or trees in a flat or hilly area, the double-sided conveying section 4 is a double-sided arc section (to bypass the obstacles).

[0133] It should be noted that the conveyor belt 5 running to the bilateral arc section is under the same force condition as the unilateral conveying section 3. Therefore, one pipe belt idler 601 arranged horizontally is provided, and two pressure belts 602 are symmetrically arranged on both sides thereof; when the two conveyor belts 5 in both directions are subject to an outward force, the first roller 6011 of the pipe belt idler 601 bears the pressure of the inner conveyor belt 5, and the second roller 6021 of the outer pressure belt 602 bears the pressure of the outer conveyor belt 5; and under the combined action of the two pressure belts 602 and the pipe belt idler 601 on both sides, the circular tube shape of the two conveyor belts 5 can be maintained without deformation or opening, thereby preventing situations such as material scattering, belt jamming, and wear.

[0134] In specific implementation, the above structure is adopted for the bilateral arc section, which can reduce the influence of the outward force on the conveyor belt 5 and further ensure the smooth progress of production and transportation.

[0135] In one embodiment, as Figure 4 shown, the bilateral conveying section 4 further includes a bilateral straight section; the conveyor belt support frame 6 arranged on the bilateral straight section is provided with two vertically arranged pipe belt idlers 601 arranged side by side, and two pressure belts 602 correspondingly arranged above the two pipe belt idlers 601; the two second arc shaping belts 6022 correspondingly form a circular channel with the same shape as the conveyor belt 5 with the two first arc shaping belts 6012.

[0136] It should be noted that the conveyor belt 5 on the bilateral straight section is equally stressed on the left and right. Therefore, two vertically arranged pipe belt idlers 601 can be provided to correspondingly carry the conveyor belt 5 in both directions; the two first rollers 6011 bear the gravity of the conveyor belt 5, and the two pressure belts 602 above correspondingly press the interface part of the conveyor belt 5 in both directions.

[0137] In specific implementation, the above structure is adopted for the bilateral straight section, which can bear the gravity of the conveyor belt 5 and press the interface of the conveyor belt 5, further ensuring the smooth progress of production and transportation.

[0138] In the embodiment provided by the present invention, as Figure 4 、 Figure 9 and Figure 10 shown, a corridor 7 is provided outside the conveyor belt support frame 6; the corridor 7 is provided with a photovoltaic panel 701 at the top and an intelligent charge and discharge control system electrically connected to the photovoltaic panel 701 inside; as Figure 11 shown, the pipe belt idler 601 further includes a drive part 702; the output end of the drive part 702 is connected to the first roller 6011 and is electrically connected to the intelligent charge and discharge control system.

[0139] It should be noted that the corridor 7 is a conveyor corridor built on the unilateral conveying section 3 and the bilateral conveying section 4, providing basic support for a number of conveyor belt support frames 6. The bottom is supported on the ground by brackets 104, and steel structure members 603 are fixed inside. Covering the corridor 7 with a ceiling can protect the conveyor belt 5 from wind, rain and reduce external environmental interference, and is also convenient for maintenance personnel to pass through.

[0140] It should be noted that the driving part 702 is preferably a speed-regulating motor; the output shaft of the motor is the output end of the driving part 702, which can drive the first roller 6011 to rotate, and then drive the loading section and the return section of the conveyor belt 5 to rotate in opposite directions.

[0141] It should be noted that as Figure 12 shown, the intelligent charge and discharge control system is a prior art, including a charge and discharge controller, energy storage batteries, sensors, LED lighting, an external power supply and an inverter, all preferably equipment in the prior art, which can achieve intelligent charge and discharge control; when the weather is clear, the photovoltaic panel 701 supplies power to the driving part 702 and stores the excess electric energy in the energy storage battery; when it is cloudy or at night, the energy storage battery can supply power to the driving part 702 and lighting equipment, or the external power supply can supply power through the inverter.

[0142] It should be noted that the plate material for closing the corridor 7 of the present invention can preferably be replaced by the photovoltaic panel 701, which can not only block wind, rain and snow, but also generate electricity using light energy.

[0143] In specific implementation, since the two-way transportation pipe belt conveyor has a long conveying distance and consists of several transportation lines, the structure of the corridor 7 can be used as the support 104 of the conveyor equipment and is also a good support 104 for the photovoltaic panel 701. At the same time, the photovoltaic panel 701 can also replace the closing material of the corridor 7, saving the land occupied by building a separate photovoltaic power generation facility, and enabling the full comprehensive utilization of material transportation and power generation, achieving inestimable efficiency; driven by an independent first roller 6011, the speed-regulating motor of the first roller 6011 of each conveyor belt support frame 6 can be controlled separately according to the actual situation, which not only increases the overall transmission driving force, but also effectively reduces the energy consumption cost.

These descriptions are not intended to limit the invention to the precise forms disclosed, and it is apparent that many changes and variations are possible in light of the above teaching.
