Description

Technical Field

[0001] The invention relates to the technical field of belt conveyors and their matching material drop adjustment equipment, in particular to a drop adjustment device. The invention also relates to a belt conveyor using the drop adjustment device. Background Art

[0002] Belt conveyor, also known as rubber belt conveyor, is a kind of material conveying equipment with strong versatility. It is widely used in power plants, mines, docks and other industries as supporting equipment for bulk material conveying.

[0003] Conventional belt conveyors are mainly composed of rollers at two ends and a closed conveyor belt tightly sleeved on the rollers. The roller that drives the conveyor belt to rotate is called a drive roller or a transmission roller; and the other roller that is only used to change the direction of the conveyor belt is called a redirecting roller. When the equipment is running, the friction between the drive roller and the conveyor belt drags the conveyor belt to complete a directional circulation action.

[0004] In the specific material conveying process, the material is fed in from the receiving end of the belt conveyor and falls on the rotating conveyor belt. The friction between the conveyor belt surface and the material drives the material to move synchronously with the conveyor belt to transport the material to the discharge end of the belt conveyor for discharge. Generally, a baffle plate is usually arranged at the corresponding position of the discharge end of the belt conveyor to adjust the material drop position from the discharge end to the next station or downstream equipment. The choice of the drop position has an important impact on the dust prevention treatment of the work site, the tracking performance of the belt operation, and the anti-dislocation treatment. Therefore, in actual applications, a corresponding adjustment mechanism is usually provided to appropriately adjust the position of the baffle plate when necessary.

[0005] At present, the industry usually adopts a plug-in mechanism or a handwheel mechanism to realize the linkage adjustment of the working position or working angle of the baffle plate. However, although this existing adjustment method can meet the basic adjustment needs of the baffle plate, its actual adjustment process is completed by manual operation of the staff, which requires the staff to overcome the deadweight of the baffle plate and the structural friction of the hinge mechanism of the baffle plate to complete the corresponding baffle plate adjustment operation. This leads to a high labor intensity for the staff in actual applications, and usually requires the cooperation of more than two staff members to complete it, consuming a lot of manpower and material resources, and in actual operation, it completely relies on manual processing, which is difficult to operate and has low operating efficiency, causing many inconveniences to the operation and maintenance of related belt conveyors.

[0006] In view of this, how to optimize the adjustment method of the baffle plate of the belt conveyor to reduce the labor intensity of related staff and effectively improve the adjustment efficiency of the baffle plate is an important technical problem that technical personnel in this field currently need to solve. Summary of the invention

[0007] The object of the present invention is to provide a material drop adjustment device, the baffle plate of which is convenient and flexible to adjust, has high adjustment efficiency, and can effectively reduce the labor intensity of relevant staff. Another object of the present invention is to provide a belt conveyor using the material drop adjustment device.

[0008] In order to solve the above technical problems, the present invention provides a material drop adjustment device, comprising a material baffle plate with a material guide groove recessed on its front end, the material guide groove is arranged in alignment with the discharge end of the conveyor belt upstream thereof, and the material guide groove extends from the top end of the material baffle plate to the bottom end thereof;

[0009] The top of the baffle plate is hinged to the frame of the belt conveyor through a reference hinge mechanism, and the rotation axis of the reference hinge mechanism extends in the horizontal direction and is perpendicular to the material conveying direction of the upstream conveyor belt;

[0010] The cam is connected to the frame of the belt conveyor through a positioning hinge mechanism, and the front end of the adjusting push rod is hinged to the lower part of the material baffle plate through a linkage hinge mechanism, and the rear end of the adjusting push rod is linkage-connected to the action end of the adjusting drive mechanism, and the rotation axes of the positioning hinge mechanism and the linkage hinge mechanism both extend in the horizontal direction and are perpendicular to the material conveying direction of the upstream conveyor belt.

[0011] Preferably, the blanking adjustment device further comprises a control system which is communicatively connected with the adjustment drive mechanism, and the control system comprises a plurality of cameras which are aligned with each station around the baffle plate.

[0012] Preferably, the control system further comprises an electric control box and a display, and the adjustment drive mechanism, the display and the camera are respectively communicatively connected to the electric control box.

[0013] Preferably, the adjustment drive mechanism is an electric cylinder electrically connected to the electric control box.

[0014] Preferably, the material baffle plate comprises a bottom shell and a plurality of wear-resistant lining plates detachably arranged on the front wall of the base, and the outer walls of the wear-resistant lining plates are tightly spliced ​​and adapted to form the material guide trough.

[0015] Preferably, extended guard plates are symmetrically arranged on both sides of the bottom shell, and the front wall of the extended guard plate is bent and matched with the front wall of the bottom shell.

[0016] Preferably, a plurality of the wear-resistant lining plates are also detachably provided on the front wall of the extended guard plate, and the outer walls of the wear-resistant lining plates on the extended guard plate are tightly spliced.

[0017] Preferably, the blanking adjustment device further comprises a front limit mechanism and a rear limit mechanism axially adapted to the adjusting push rod.

[0018] Preferably, there are two reference hinge mechanisms, and the two reference hinge mechanisms are symmetrically arranged on both sides of the baffle plate.

[0019] The present invention also provides a belt conveyor, comprising a frame and a conveyor belt arranged on the frame, and also comprising a material drop adjustment device cooperating with the conveyor belt, wherein the material drop adjustment device is a material drop adjustment device as described in any one of the above items.

[0020] Compared with the above background technology, the material drop adjustment device provided by the present invention, during its operation, the material sent from the discharge end of the upstream conveyor belt falls onto the guide trough, so that the inclined arrangement structure of the guide trough itself is used to smoothly guide the material to the downstream workstation or conveyor belt to ensure the material transfer efficiency of the belt conveyor. When the drop position downstream of the guide trough needs to be adjusted due to the adjustment of operation requirements or the change of working conditions, the action end of the adjustment drive mechanism can be used to drive the adjustment push rod to move appropriately along its axial direction to drive the lower part of the baffle plate to be adjusted synchronously. Since the upper part of the baffle plate is hinged to the frame of the belt conveyor or the main support structure of the equipment such as the upstream head hopper through the reference hinge mechanism, the axial movement of the adjustment push rod will drive the baffle plate to form a circumferential rotation around the hinge shaft of the reference hinge mechanism. Therefore, the adjustment drive mechanism can be used to drive the adjustment push rod to move axially back and forth to drive the baffle plate to rotate appropriately, so as to appropriately adjust the pitch angle of the front end surface of the baffle plate, and thereby achieve the corresponding adjustment of the pitch angle and position of the guide trough. When the pitch angle of the guide trough is adjusted to a suitable state, the adjustment drive mechanism stops moving, so that the adjustment push rod maintains the current axial position to meet the subsequent material transfer and material guiding operation requirements. If the pitch angle and matching position of the baffle plate and the guide trough still need to be adjusted later, it is only necessary to repeat the above-mentioned operation process of adjusting the drive mechanism and adjusting the push rod. The blanking adjustment device uses the adjustment drive mechanism to drive the axial reciprocating movement of the adjustment push rod to achieve the linkage adjustment of the pitch angle of the baffle plate, so as to achieve the corresponding adjustment of the pitch angle and matching position of the guide trough, so that the staff does not need to manually overcome the deadweight of the baffle plate and the hinge resistance to implement the adjustment of the baffle plate, which greatly reduces the labor intensity of the staff. In addition, the blanking adjustment device in this scheme can adjust the entire pitch angle and position of the baffle plate smoothly and conveniently, which can improve the adjustment efficiency of the baffle plate accordingly.

[0021] In another preferred embodiment of the present invention, the material drop adjustment device further includes a control system that is communicatively connected to the adjustment drive mechanism, and the control system includes a plurality of cameras that are aligned with each station around the baffle plate. Each camera can be used to monitor the equipment operation status and material conveying status above, below, and even in front and behind the baffle plate, so that the monitoring and operating personnel can adjust the pitch angle of the baffle plate in time according to the changes in the actual working conditions, so as to achieve adaptive adjustment of the pitch angle and matching position of the guide trough, so as to adjust the drop position of the material after the material guide processing by the baffle plate to a state that can meet the current working condition requirements, ensure the overall operation efficiency of the belt conveyor, and improve the working condition adaptability of the belt conveyor accordingly.

[0029] The core of the present invention is to provide a material drop adjustment device, the baffle plate of which is convenient and flexible to adjust, has high adjustment efficiency, and can effectively reduce the labor intensity of relevant staff; the present invention also provides a belt conveyor using the above-mentioned material drop adjustment device.

[0030] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Please refer to Figure 1 .

[0032] In a specific embodiment, the material drop adjustment device provided by the present invention includes a material baffle plate 11 with a material guide groove 111 recessed on the front end surface. The material guide groove 111 is arranged in alignment with the discharge end of the upstream conveyor belt, and the material guide groove 111 extends from the top end of the material baffle plate 11 to the bottom end thereof.

[0033] Correspondingly, the top of the material blocking plate 11 is hinged to the frame of the belt conveyor through a reference hinge mechanism 112, and the rotation axis of the reference hinge mechanism 112 extends in the horizontal direction and is perpendicular to the material conveying direction of the upstream conveyor belt.

[0034] The material dropping adjustment device also includes an adjusting push rod 12 and an adjusting drive mechanism capable of driving the adjusting push rod 12 to move axially back and forth. The adjusting drive mechanism is hinged to the frame of the belt conveyor through a positioning hinge mechanism 122. The front end of the adjusting push rod 12 is hinged to the lower part of the material baffle plate 11 through a linkage hinge mechanism 123, and the rear end of the adjusting push rod 12 is linkage-connected to the action end of the adjusting drive mechanism. The rotation axes of the positioning hinge mechanism 122 and the linkage hinge mechanism 123 both extend in the horizontal direction and are perpendicular to the material conveying direction of the upstream conveyor belt.

[0035] During the operation of the equipment, the material delivered from the discharge end of the upstream conveyor belt falls onto the guide trough 111, and the inclined arrangement structure of the guide trough 111 is used to smoothly guide the material to the downstream workstation or conveyor belt to ensure the material transfer efficiency of the belt conveyor.

[0036] When the material drop position downstream of the guide chute 111 needs to be adjusted due to adjustment of work requirements or changes in working conditions, the action end of the adjustment drive mechanism can be used to drive the adjustment push rod 12 to move appropriately along its axial direction, so as to drive the lower part of the material baffle plate 11 to be adjusted synchronously. Since the upper part of the material baffle plate 11 is hinged to the frame of the belt conveyor or the main supporting structure of the equipment such as the upstream head hopper through the reference hinge mechanism 112, the axial movement of the adjustment push rod 12 will drive the material baffle plate 11 to form a circumferential rotation around the hinge axis of the reference hinge mechanism 112. Therefore, the adjustment drive mechanism can be used to drive the adjustment push rod 12 to make axial reciprocating movement to drive the material baffle plate 11 to rotate appropriately, thereby appropriately adjusting the pitch angle of the front end surface of the material baffle plate 11, and thereby achieving corresponding adjustment of the pitch angle and position of the material guide chute 111.

[0037] When the pitch angle of the material guide trough 111 is adjusted to an appropriate state, the adjustment drive mechanism stops moving so that the adjustment push rod 12 maintains the current axial position to meet the subsequent material transfer and material guiding operation requirements. If the pitch angle and matching position of the baffle plate 11 and the material guide trough 111 still need to be adjusted later, it is only necessary to repeat the above-mentioned operation process of adjusting the drive mechanism and adjusting the push rod 12.

[0038] The material dropping adjustment device utilizes the adjustment driving mechanism to drive the axial reciprocating movement of the adjustment push rod 12 to realize the linkage adjustment of the pitch angle of the material baffle plate 11, so as to achieve the corresponding adjustment of the pitch angle and the matching position of the material guide trough 111, thereby eliminating the need for staff to manually overcome the deadweight of the material baffle plate 11 and the hinge resistance to implement the adjustment of the material baffle plate 11, which greatly reduces the labor intensity of the staff, and the material dropping adjustment device in the present scheme can smoothly and conveniently adjust the entire pitch angle and position of the material baffle plate 11, which can improve the adjustment efficiency of the material baffle plate 11 accordingly.

[0039] Generally, the reference hinge mechanism 112, the positioning hinge mechanism 122 and the linkage hinge mechanism 123 can all be realized by using hinge mechanisms that match the hinge seat and the hinge shaft, and other types of hinge mechanisms can also be selected according to actual working conditions and assembly space layout. In actual applications, the staff can flexibly select and adjust. In principle, any hinge mechanism that can meet the actual application needs of the blanking adjustment device can be used.

[0040] Accordingly, during the axial reciprocating motion of the adjusting push rod 12, due to the action of the linkage hinge mechanism 123 between the adjusting push rod 12 and the material blocking plate 11, the adjusting drive mechanism will be subjected to the swing stress along the rotation direction of the hinge axis of the positioning hinge mechanism 122. In view of this, the positioning hinge mechanism 122 is used as the installation basis between the adjusting drive mechanism and the belt conveyor frame, so that when the adjusting push rod 12 is subjected to the above-mentioned swing stress, it can moderately reciprocate and swing slightly along the action trend of the stress, so as to avoid local stress concentration or structural interference leading to damage or jamming of the adjusting drive mechanism and the adjusting push rod 12 and other supporting action parts, thereby further ensuring the adjustment efficiency of the material blocking plate 11, making the operation of the blanking adjustment device smoother, and the component adaptation structure safer and more reliable.

[0041] Specifically, the material drop adjustment device also includes a control system that is communicatively connected to the adjustment drive mechanism, and the control system includes a plurality of cameras 131 that are aligned with each station around the baffle plate 11. Each camera 131 can be used to monitor the equipment operation status and material conveying status above, below, and even at various positions in front and behind the baffle plate 11, so that the monitoring and operating personnel can adjust the pitch angle of the baffle plate 11 in time according to the changes in the actual working conditions, so as to achieve adaptive adjustment of the pitch angle and the matching position of the guide trough 111, so as to adjust the drop position of the material after the material guide processing by the baffle plate 11 to a state that can meet the current working condition requirements, ensure the overall operation efficiency of the belt conveyor, and improve the working condition adaptability of the belt conveyor accordingly.

[0042] Furthermore, the control system further includes an electric control box 13 and a display 132, and the adjustment drive mechanism, the display 132 and the camera 131 are respectively connected to the electric control box 13. Specifically, the adjustment drive mechanism is preferably an electric cylinder 121 that can be electrically connected and matched with the electric control box 13, so that the staff can flexibly adjust the telescopic range and working state of the action end of the electric cylinder 121 by using the electric control box 13 according to the actual working conditions, so as to control and adjust the axial movement position of the push rod 12, thereby realizing the linkage adjustment of the pitch angle of the baffle plate 11 and the corresponding blanking position.

[0043] Furthermore, there are two displays 132, one of which can be arranged at the work site and can be directly installed near the electric control box 13, so that through the communication connection between the display 132 and each camera 131, the on-site staff can observe the material conveying status near the baffle plate 11 and the operating status of moving parts such as the conveyor belt in real time through the display 132, so as to timely use the electric control box 13 to adjust the operating status of the corresponding parts or devices; the other display 132 can be arranged in the central control room of the coal transportation system or other material transportation systems that are used in conjunction with the currently operating belt conveyor, so that the factory supervisory personnel can timely understand the equipment operating conditions at the positions photographed by each camera 131, so that when the on-site staff fails to discover the changes in the operating conditions in time, the supervisory personnel in the central control room can promptly notify the on-site staff, thereby ensuring that the on-site staff can quickly and accurately implement the corresponding equipment control and operating condition adjustment, thereby further improving the operating safety and work efficiency of related large systems such as the coal transportation system.

[0044] On the other hand, the material blocking plate 11 includes a bottom shell 113 and a plurality of wear-resistant lining plates 114 detachably arranged on the front wall of the base, and the outer walls of the wear-resistant lining plates 114 on the bottom shell 113 are closely spliced ​​and adapted to form the material guide trough 111. The wear-resistant lining plates 114 are generally mounted on the bottom shell 113 by connecting parts such as countersunk bolts that are easy to disassemble, and the connecting structure thereof is preferably a threaded connecting part such as bolts and screws to ensure the structural strength and reliability after assembly.

[0045] Since the above-mentioned multiple wear-resistant lining plates 114 are assembled and spliced ​​to form a covering protection for the front wall of the baffle plate 11, the wear and structural damage to the main basic structural parts of the baffle plate 11 such as the bottom shell 113 caused by frequent contact and friction of materials during the operation of the equipment are effectively avoided. After the equipment has been running for a period of time, if individual wear-resistant lining plates 114 are excessively worn or damaged, the corresponding damaged or excessively worn wear-resistant lining plates 114 can be removed, and then new wear-resistant lining plates 114 can be replaced in the corresponding positions to ensure the structural integrity of the baffle plate 11 and the guide trough 111. In this way, the individual replacement of local components can be achieved without the need to disassemble and replace the baffle plate 11 as a whole, thereby effectively reducing the use and maintenance costs of the blanking adjustment device.

[0046] Specifically, the two sides of the bottom shell 113 are symmetrically arranged with extended guard plates 115, and the front wall of the extended guard plate 115 is bent and matched with the front wall of the bottom shell 113. The extended guard plate 115 can significantly increase the structural extension of the side of the baffle plate 11, so as to prevent the material sent from the discharge end of the upstream conveyor belt from escaping through the two sides of the guide trough 111, thereby ensuring that the material can accurately and efficiently fall into the effective range of the guide trough 111 and be guided to the corresponding drop position by the guide trough 111. As a result, the material conveying operation of the belt conveyor is smoother and more efficient.

[0047] Bending fit means that an angle is formed between the main extension surface of the front wall of the extension guard plate 115 and the main extension surface of the front wall of the bottom shell 113, and the angle is greater than 0° and less than 180°. The angle is generally an obtuse angle, and can also be an acute angle for some special working conditions.

[0048] More specifically, a plurality of wear-resistant lining plates 114 are also detachably mounted on the front wall of the extended guard plate 115, and the outer walls of the wear-resistant lining plates 114 on the extended guard plate 115 are closely spliced. In this way, the main basic structure of the extended guard plate 115 is also effectively protected by the wear-resistant lining plates 114, and in actual applications, if the wear-resistant lining plates 114 on the extended guard plate 115 are damaged, the corresponding damaged wear-resistant lining plates 114 can be removed separately and replaced with new wear-resistant lining plates 114 at the corresponding positions, so as to ensure the material guiding effect and structural reliability of the extended guard plate 115.

[0049] Correspondingly, each wear-resistant liner 114 on the extended guard plate 115 is preferably installed using countersunk bolts or other threaded connectors, and ensures that the corresponding wear-resistant liner 114 can be flexibly disassembled to facilitate individual replacement and maintenance needs.

[0050] In addition, the blanking adjustment device also includes a front limit mechanism and a rear limit mechanism that are axially adapted to the adjusting push rod 12. When the equipment is actually running, the front limit mechanism can effectively limit the limit position of the adjusting push rod 12 moving forward in the axial direction, thereby avoiding structural damage or component structural failure caused by excessive forward movement of the adjusting push rod 12; correspondingly, the rear limit mechanism can effectively limit the limit position of the adjusting push rod 12 moving backward in the axial direction, thereby avoiding structural damage or component structural failure caused by excessive backward movement of the adjusting push rod 12.

[0051] Generally, the front limit mechanism and the rear limit mechanism can be a block or a locking sleeve that can be adapted to the adjusting push rod 12, or a mechanical switch or an electric control switch that can be adapted to the adjusting drive mechanism. In particular, if the electric cylinder 121 is used as the specific application type of the adjusting drive mechanism and the electric control box 13 is arranged in conjunction with it, a mechanical switch or an electric control switch that can cooperate with the electric cylinder 121 can be used to realize the control of the bidirectional action stroke of the actuating end of the electric cylinder 121, so as to achieve the limitation of the axial movement limit position of the adjusting push rod 12, and correspondingly achieve the limitation of the reciprocating pitch adjustment limit position of the material baffle plate 11, so as to avoid the loosening, dislocation or damage of the material baffle plate 11 due to excessive movement.

[0052] In addition, there are two reference hinge mechanisms 112, and the two reference hinge mechanisms 112 are symmetrically arranged on both sides of the baffle plate 11. The hinge mechanisms symmetrically arranged on both sides can effectively improve the top structural support strength of the baffle plate 11 and make the pitch rotation adjustment of the baffle plate 11 smoother and more stable.

[0053] Accordingly, three or more anchor points for installation can be arranged on the structural components such as the frame or hopper of the belt conveyor that can serve as the installation base of the baffle plate 11, and used as optional installation positions of the reference hinge mechanism 112. This can further optimize the adaptation position adjustment range of the baffle plate 11 and the material, thereby correspondingly improving the overall working condition adaptability of the baffle plate 11 and even the blanking adjustment device, so as to meet the blanking position adjustment and material conveying operation requirements under different working conditions.

[0054] In a specific embodiment, the belt conveyor provided by the present invention includes a frame and a conveyor belt arranged on the frame, and also includes a material drop adjustment device matched with the conveyor belt, and the material drop adjustment device is the material drop adjustment device as described above. The baffle plate 11 of the material drop adjustment device of the belt conveyor is relatively convenient and flexible to adjust, and its adjustment efficiency is high, and it can effectively reduce the labor intensity of relevant staff.

[0055] In summary, it can be seen that during the operation of the material drop adjustment device provided in the present invention, the material delivered from the discharge end of the upstream conveyor belt falls onto the material guide trough, thereby utilizing the inclined arrangement structure of the material guide trough itself to smoothly guide the material to the downstream workstation or conveyor belt, thereby ensuring the material transfer efficiency of the belt conveyor. When the material drop position downstream of the material guide chute needs to be adjusted due to adjustment of work requirements or changes in working conditions, the action end of the adjustment drive mechanism can be used to drive the adjustment push rod to move appropriately along its axial direction, so as to drive the lower part of the material baffle plate to be adjusted synchronously. Since the upper part of the material baffle plate is hinged to the frame of the belt conveyor or the main supporting structure of the equipment such as the upstream head hopper through a reference hinge mechanism, the axial movement of the adjustment push rod will drive the material baffle plate to form a circumferential rotation around the hinge axis of the reference hinge mechanism. Therefore, the adjustment drive mechanism can be used to drive the adjustment push rod to make axial reciprocating movement to drive the material baffle plate to rotate appropriately, thereby appropriately adjusting the pitch angle of the front end face of the material baffle plate, and thereby achieving corresponding adjustment of the pitch angle and position of the material guide chute. When the pitch angle of the guide trough is adjusted to a suitable state, the adjustment drive mechanism stops moving, so that the adjustment push rod maintains the current axial position to meet the subsequent material transfer and material guiding operation requirements. If the pitch angle and matching position of the baffle plate and the guide trough still need to be adjusted later, it is only necessary to repeat the above-mentioned operation process of adjusting the drive mechanism and adjusting the push rod. The blanking adjustment device uses the adjustment drive mechanism to drive the axial reciprocating movement of the adjustment push rod to achieve the linkage adjustment of the pitch angle of the baffle plate, so as to achieve the corresponding adjustment of the pitch angle and matching position of the guide trough, so that the staff does not need to manually overcome the deadweight of the baffle plate and the hinge resistance to implement the adjustment of the baffle plate, which greatly reduces the labor intensity of the staff. In addition, the blanking adjustment device in this scheme can adjust the entire pitch angle and position of the baffle plate smoothly and conveniently, which can improve the adjustment efficiency of the baffle plate accordingly.

[0056] The present invention also provides a belt conveyor, wherein the material baffle plate of the material drop adjustment device is convenient and flexible to adjust, has high adjustment efficiency, and can effectively reduce the labor intensity of relevant staff.

[0057] The above is a detailed introduction to the blanking adjustment device provided by the present invention and the belt conveyor using the blanking adjustment device. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
