Description

Technical Field

[0001] The invention relates to the technical field of belt conveyors, in particular to a safe belt conveyor system. Background Art

[0002] At present, the transportation of coal in mines is all done by belt conveyors. The mined coal is transported to storage places by belt conveyors. Sometimes, in order to increase the amount of coal mined, it is necessary to increase the carrying capacity of various equipment, including improving the conveying efficiency of belt conveyors. When the conveyor belt transports a large amount of coal, the coal is very easy to detach from the edge of the conveyor belt during the transportation process, affecting the transportation of the coal and the amount of coal transported.

[0003] In the prior art, inclined rollers are generally used to fold the two side edges of the conveyor belt upward at a certain angle, so as to prevent the coal on the conveyor belt from falling from the side of the conveyor belt. However, when the coal falls onto the conveyor belt, it will cause a certain impact on the conveyor belt and the bracket. After a long time, the conveyor belt will loosen, which may easily cause the conveyor belt to slip. In addition, the existing conveyor belt only has an adjustment function for the folding angle of the side of the conveyor belt. However, the width of the foldable side is fixed, and the effective conveying width of the conveyor belt cannot be adjusted. The adjustment freedom of the conveyor belt is limited. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a safe belt transportation system, which can cushion the impact of coal falling onto the conveyor belt, and keep the conveyor belt in a taut state when it is impacted, so as to avoid the conveyor belt from loosening after a long time of impact and avoid the conveyor belt from slipping. The width of the side of the conveyor belt that can be folded can be adjusted to effectively prevent the coal from detaching from the edge of the conveyor belt, and can also change the effective conveying width of the conveyor belt. The conveying speed of the coal can be changed when the running speed of the conveyor belt is constant. The conveyor belt has a high degree of freedom in adjustment and can adapt to the coal transportation needs in different situations, which can effectively solve the problems in the background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a safe belt conveyor system, comprising a horizontal seat plate, and further comprising:

[0006] The belt transport assembly comprises a conveying end roller and a conveying belt, wherein the left and right ends of the horizontal seat plate are rotatably connected to two longitudinal conveying end rollers, and the two conveying end rollers are connected by the conveying belt;

[0007] The falling material anti-impact mechanism comprises a column, a lower spring, a lower end block, a lower support roller, an upper spring and a longitudinal support plate, a plurality of longitudinal support plates are arranged at equal distances laterally on the upper side of the horizontal seat plate, the front and rear ends of the bottom of each longitudinal support plate are respectively fixedly connected to the bottom ends of the two columns, each column is respectively slidably connected to the corresponding column holes in the horizontal seat plate, and the bottom end of each column is respectively fixedly connected to the lower end block, and a longitudinal lower support roller is rotatably connected between the two corresponding lower end blocks, the bottom of the lower support roller contacts the bottom inner side of the conveyor belt, the column section of each column located on the upper side of the horizontal seat plate is respectively sleeved with an upper spring, the upper and lower ends of the upper spring are respectively connected to the longitudinal support plate and the horizontal seat plate, the column section of each column located on the lower side of the horizontal seat plate is respectively sleeved with a lower spring, and the upper and lower ends of the lower spring are respectively connected to the horizontal seat plate and the lower end block;

[0008] The belt upper supporting mechanism is installed on the longitudinal supporting plate, and the front and rear ends of the belt upper supporting mechanism are respectively installed with coal transport thickness adjusting mechanisms.

[0009] The rear end of the conveying end roller on the left is connected to a power source, which is composed of a motor and a gear box. The power source drives the conveying end roller on the left to rotate counterclockwise, and the conveying end roller on the left drives the conveying end roller on the right to rotate counterclockwise through the transmission of the conveying belt. The conveying belt rotates counterclockwise, and the coal falls to the upper right end of the conveying belt, and then is transported to the upper left end of the conveying belt as the conveying belt rotates, thereby realizing the transportation of the coal. When a large amount of coal falls to the upper right end of the conveying belt, it will have a certain impact force on the conveying belt. At this time, the impact force of the coal has a downward impact force on the upper support mechanism of the belt through the conveying belt. When the longitudinal support plate is subjected to downward pressure, it drives the column to move downward relative to the horizontal seat plate. At this time, as the top of the conveying belt It is concave downward, but the column drives the lower support roller to descend through the lower end block, so that the lower support roller can tighten the bottom of the conveyor belt downward to keep the conveyor belt in a tightened state. At this time, the upper spring is compressed and the lower spring is stretched. The upper and lower springs can buffer the impact force of the coal on the conveyor belt. Then, with the help of the restoring force of the upper and lower springs, the column is moved up again relative to the horizontal seat plate, and the top and bottom of the conveyor belt gradually return to a flat state. During this process, the conveyor belt always remains in a tightened state. The belt upper support mechanism is used to support the top inner side of the conveyor belt. The coal transportation thickness adjustment mechanism can fold the side of the conveyor belt upward. The thickness of the coal transported on the conveyor belt can be changed according to the folding angle.

[0010] Furthermore, the belt upper support mechanism includes a opposing movement control component, a length control vertical rod, a longitudinal support plate, a roller sleeve and an intermediate roller. The longitudinal support plate is connected to two front and rear corresponding length control vertical rods through the opposing movement control component. The two length control vertical rods are fixedly connected to two longitudinal support plates on the sides away from each other. The two longitudinal support plates are longitudinally slidably connected to the top of the longitudinal support plate. The tops of the two length control vertical rods on the sides close to each other are respectively rotationally connected to one end of the two roller sleeves, and the other ends of the two roller sleeves are respectively slidably connected to the front and rear ends of a longitudinal intermediate roller. The opposite movement control assembly is used to drive the two length control vertical rods to approach or move away from each other, and the two length control vertical rods respectively move the two longitudinal support plates. When the two length control vertical rods approach each other, the two roller sleeves gradually move toward the middle of the middle roller. At this time, the length of the roller formed by the two roller sleeves and the middle roller becomes shorter, and the supporting width of the conveyor belt by the roller is reduced, then the effective conveying width of the conveyor belt is reduced, and the conveying speed of the coal is reduced when the running speed of the conveyor belt is constant. When the length control vertical rods move away from each other, the two roller sleeves move away from each other. At this time, the length of the roller formed by the two roller sleeves and the middle roller becomes longer, and the supporting width of the conveyor belt by the roller is increased, then the effective conveying width of the conveyor belt is increased, and the conveying speed of the coal is increased when the running speed of the conveyor belt is constant.

[0011] Furthermore, the coal transportation thickness adjustment mechanism includes a movable seat 1, an adjustment cylinder, a movable seat 2, a movable block 1, an inclined roller and a movable block 2. The top of one end of each longitudinal support plate away from the length control vertical rod is fixedly connected with a movable seat 1. Each movable seat 1 is movably connected to the bottom end of the adjustment cylinder through a movable shaft 1. The top of each adjustment cylinder is fixedly connected with a movable seat 2. Each movable seat 2 is movably connected to a movable block 1 through a movable shaft 2. Each movable block 1 is rotatably connected to one end of the inclined roller. The other end of each inclined roller is rotatably connected to a movable block 2. Each movable block 2 is movably connected to the corresponding top of the length control vertical rod through a movable shaft 3. The inclined roller is rollingly connected to the lower side of the top side of the conveyor belt.

[0012] The coal transportation thickness adjustment mechanism changes the position of the upward folding support of the conveyor belt as the longitudinal support plate moves. When the length of the roller formed by the two roller sleeves and the middle roller increases, the width of the side of the conveyor belt that the coal transportation thickness adjustment mechanism can fold will decrease due to the fixed width of the conveyor belt. On the contrary, when the length of the roller formed by the two roller sleeves and the middle roller decreases, the width of the side of the conveyor belt that the coal transportation thickness adjustment mechanism can fold will increase.

[0013] Control the extension of the adjustment cylinder, and the adjustment cylinder pushes the top of the inclined roller to rise, so that the inclination angle of the inclined roller becomes larger, and the folding angle of the side of the conveyor belt increases. At this time, the thickness of the coal that can be transported on the conveyor belt will become larger, and even if there is thicker coal on the conveyor belt, it is not easy to fall from the side;

[0014] The control adjustment cylinder is shortened, the inclination angle of the inclined roller is reduced, the folding angle of the side of the conveyor belt becomes smaller, and the thickness of the coal that can be transported on the conveyor belt becomes smaller.

[0015] Furthermore, it also includes a dust reduction and dust elimination mechanism, which includes an anti-slip baffle, a guide inclined plate and an atomizing dust reduction component. Two anti-slip baffles are respectively provided on the front and rear sides of the left end of the conveying end roller on the left side, and a guide inclined plate is fixedly connected between the middle parts of the two anti-slip baffles. The guide inclined plate is tilted so that the left side is low and the right side is high, and the right end of the guide inclined plate corresponds to the middle part of the left side of the conveying end roller. An atomizing dust reduction component is installed between the tops of the two anti-slip baffles. Due to the existence of the conveying end roller on the left side, the conveying belt gradually becomes horizontal when approaching the conveying end roller on the left side. When the coal is transported to the left end on the conveying belt, it is easy to fall from the front and rear sides of the conveying end roller. At this time, the anti-slip baffle can block the front and rear sides of the left end of the conveying belt, so that the coal on the conveying belt can smoothly fall onto the guide inclined plate, and then slide to the left along the guide inclined plate. Since the coal is easy to raise dust when sliding, an atomizing dust reduction component is provided. The atomizing dust reduction component is used for spraying water by atomization to avoid raising dust and improve the safety of the transportation site.

[0016] Furthermore, the atomizing dust reduction assembly includes a dust reduction longitudinal pipe, a solenoid valve 1, a water supply pipe 1, a water pump and a dust reduction atomizing nozzle. A dust reduction longitudinal pipe is arranged between the tops of the two anti-slip baffles. A dust reduction atomizing nozzle is arranged at an equal distance on the side of the dust reduction longitudinal pipe close to the conveying end roller. One end of the dust reduction longitudinal pipe is connected to one end of the water supply pipe 1 through a solenoid valve 1, and the other end of the water supply pipe 1 is connected to the water outlet of the water pump. The water pump draws water from an external water source, opens the solenoid valve 1, and the water pump delivers water into the dust reduction longitudinal pipe through the water supply pipe 1. The water in the dust reduction longitudinal pipe is sprayed out through the dust reduction atomizing nozzle, and the dust raised is reduced by water mist, thereby improving the safety of the site.

[0017] Furthermore, it also includes a cooling mechanism, which includes a water supply pipe 2, a solenoid valve 2, a cooling longitudinal pipe and a cooling spray head. A cooling longitudinal pipe is arranged between the bottoms of the two anti-slip baffles, and a cooling spray head is arranged at an equal distance on the side of the cooling longitudinal pipe close to the conveying end roller. One end of the cooling longitudinal pipe is connected to one end of the water supply pipe 2 through the solenoid valve 2, and the other end of the water supply pipe 2 is connected to the water supply pipe 1. Since the conveying belt and the conveying end roller have a large friction force, the conveying belt is prone to high temperature, which has a great safety hazard. If the conveying belt is hot, the solenoid valve 2 is opened, and the water in the water supply pipe 1 enters the cooling longitudinal pipe through the water supply pipe 2 and the solenoid valve 2. The water in the cooling longitudinal pipe is sprayed onto the conveying belt through the cooling spray head, which is conducive to cooling the conveying belt and improving the safety during coal transportation.

[0018] Furthermore, it also includes a belt correcting mechanism, which includes an installation support assembly, a rectangular frame, a rotating shaft, a longitudinal axis, a correcting sleeve and a correcting control assembly. A longitudinal rectangular frame is installed on the upper left end of the horizontal seat plate through the installation support assembly. The middle part of the rectangular frame is movably connected to the middle part of the longitudinal axis through a transverse rotating shaft. The front and rear ends of the longitudinal axis are respectively rotatably connected to two correcting sleeves, and the bottom of the longitudinal axis is connected to a correcting control assembly. The conveyor belt is prone to deviate from the conveyor end roller as it runs, so it is necessary to use a belt correction mechanism to correct the conveyor belt. When the conveyor belt deviates to the front side relative to the conveyor end roller, the correction control component controls the longitudinal axis to move around the rotating shaft, so that the longitudinal axis is tilted high at the front and low at the back. At this time, the correction sleeve at the front end of the longitudinal axis is lifted, and the correction sleeve is in rolling contact with the top inner side of the conveyor belt. Since the correction sleeve is tilted high at the front and low at the back, the conveyor belt can move backward relative to the conveyor end roller on the left. When the conveyor belt deviates to the back side relative to the conveyor end roller, the correction control component tilts the longitudinal axis low at the front and high at the back, and the correction sleeve at the rear end of the longitudinal axis is in rolling contact with the top inner side of the conveyor belt, so that the conveyor belt moves forward relative to the conveyor end roller on the left, thereby gradually correcting the conveyor belt.

[0019] Furthermore, the deflection correction control assembly includes a movable seat 3, a deflection correction cylinder and a movable seat 4. The bottom of the longitudinal axis is fixedly connected to the movable seat 4, and the movable seat 4 is movably connected to the top of the deflection correction cylinder through a movable shaft 4. The bottom of the deflection correction cylinder is movably connected to the movable seat 3 through a movable shaft 5. The movable seat 3 is installed on the mounting support assembly. The movable seat 4 is located on the front side of the rotating shaft. When the deflection correction cylinder is extended, the longitudinal axis will be tilted to a higher front and a lower rear. When the deflection correction cylinder is shortened, the longitudinal axis will be tilted to a lower front and a higher rear.

[0020] Furthermore, it also includes a belt edge limiting mechanism, which includes a counter-synchronous moving component, an edge limiting ring and an anti-wear ring. The two ends of each conveying end roller are respectively connected to two edge limiting rings through the counter-synchronous moving component. The two edge limiting rings are respectively provided with anti-wear rings on the sides close to each other, and the outer edge thickness of the anti-wear ring is less than the inner edge thickness. The counter-synchronous moving component can drive the two edge limiting rings to approach each other or move away from each other synchronously. The two edge limiting rings can allow the two anti-wear rings to approach the front and rear sides of the conveying belt. The front and rear sides of the conveying belt are limited by the two anti-wear rings to avoid the conveying belt from deviating relative to the conveying end roller, which is conducive to the smooth and correct operation of the conveying belt. The anti-wear ring can be made of a suitable material, such as ceramic material, to reduce the wear on the side of the conveying belt.

[0021] Furthermore, it also includes a belt tension adjustment mechanism, which includes a tension roller and a tension adjustment component. A longitudinal tension roller is installed at the bottom center of the horizontal seat plate through the tension adjustment component, and the top of the tension roller contacts the lower side of the conveyor belt. The tension adjustment component can drive the tension roller to move up and down, thereby changing the tension state of the conveyor belt. When the tension adjustment component drives the tension roller to rise, the tension roller tightens the conveyor belt. When the tension adjustment component drives the tension roller to descend, the tension roller reduces the tension force on the conveyor belt.

[0022] Compared with the prior art, the beneficial effects of this safe belt conveyor system are:

[0023] 1. When a large amount of coal falls to the upper right end of the conveyor belt, it will have a certain impact force on the conveyor belt. At this time, the impact force of the coal has a downward impact force on the upper support mechanism of the belt through the conveyor belt. When the longitudinal support plate is subjected to downward pressure, it drives the column to move downward relative to the horizontal seat plate. At this time, as the top of the conveyor belt sinks downward, the column drives the lower support roller to descend through the lower end block, allowing the lower support roller to tighten the bottom of the conveyor belt downward, so that the conveyor belt remains in a tightened state.

[0024] 2. The upper spring and the lower spring can buffer the impact force caused by the coal on the conveyor belt, and can buffer the impact of the coal falling on the conveyor belt, to prevent the conveyor belt from loosening after a long period of impact, and to prevent the conveyor belt from slipping.

[0025] 3. The width of the foldable side of the conveyor belt can be adjusted to effectively prevent the coal from falling off the edge of the conveyor belt. It can also change the effective conveying width of the conveyor belt and change the coal conveying speed when the conveyor belt runs at a constant speed. The conveyor belt has a high degree of freedom in adjustment and can adapt to the coal transportation needs in different situations. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] For example, see Figures 1 to 10 The present embodiment provides a safe belt conveyor system, which includes a horizontal seat plate 1, a belt conveyor assembly 2, a falling material anti-impact mechanism 5 and a belt upper support mechanism 6.

[0039] Specifically, the belt transport assembly 2 includes a conveying end roller 22 and a conveying belt 23 . The left and right ends of the horizontal seat plate 1 are rotatably connected to two longitudinal conveying end rollers 22 , and the two conveying end rollers 22 are connected by the conveying belt 23 .

[0040] The belt transport assembly 2 further includes a support 21. Two supports 21 are respectively arranged at the left and right ends of the horizontal seat plate 1. The front and rear ends of each conveying end roller 22 are rotatably connected to the corresponding support 21 through bearings.

[0041] The falling material anti-impact mechanism 5 includes a column 51, a lower spring 52, a lower end block 53, a lower support roller 54, an upper spring 55 and a longitudinal support plate 56. A plurality of longitudinal support plates 56 are arranged at equal distances on the upper side of the horizontal seat plate 1. The number of longitudinal support plates 56 is selected according to needs. In this embodiment, four longitudinal support plates 56 are used. The front and rear ends of the bottom of each longitudinal support plate 56 are respectively fixedly connected to the bottom ends of the two columns 51. Each column 51 is respectively slidably connected to the corresponding column hole on the horizontal seat plate 1, and the bottom end of each column 51 is respectively fixedly connected to the bottom end of each column 51. There is a lower end block 53, and a longitudinal lower support roller 54 is rotatably connected between the two corresponding lower end blocks 53 at the front and rear ends. The bottom of the lower support roller 54 contacts the bottom inner side of the conveyor belt 23. The column section of each column 51 located on the upper side of the horizontal seat plate 1 is respectively sleeved with an upper spring 55, and the upper and lower ends of the upper spring 55 are respectively connected to the longitudinal support plate 56 and the horizontal seat plate 1, and the column section of each column 51 located on the lower side of the horizontal seat plate 1 is respectively sleeved with a lower spring 52, and the upper and lower ends of the lower spring 52 are respectively connected to the horizontal seat plate 1 and the lower end block 53.

[0042] The belt upper supporting mechanism 6 is installed on the longitudinal supporting plate 56, and the front and rear ends of the belt upper supporting mechanism 6 are respectively installed with coal transport thickness adjustment mechanisms 7.

[0043] The belt upper support mechanism 6 includes a opposing movement control component, a length control vertical rod 63, a longitudinal support plate 66, a roller sleeve 69 and an intermediate roller 610. Two front and rear corresponding length control vertical rods 63 are connected to the longitudinal support plate 56 through the opposing movement control component. The two length control vertical rods 63 are fixedly connected to two longitudinal support plates 66 on the sides away from each other. The two longitudinal support plates 66 are both longitudinally slidably connected to the top of the longitudinal support plate 56. The tops of the sides where the two length control vertical rods 63 are close to each other are respectively rotated to connect one end of the two roller sleeves 69, and the other ends of the two roller sleeves 69 are respectively slidably sleeved with the front and rear ends of a longitudinal intermediate roller 610.

[0044] The belt upper support mechanism 6 also includes a slide 67 and a slide bar 68. The two ends of the top of the longitudinal support plate 56 are respectively fixedly connected to two slides 67, and the bottoms of the two longitudinal support plates 66 are respectively fixedly connected to two slide bars 68. Each slide bar 68 is respectively connected to the corresponding slide 67 for longitudinal sliding. With the help of the cooperation of the slide 67 and the slide bar 68, the longitudinal support plate 66 can only move forward and backward, thereby improving the stability of the length control vertical rod 63 and the longitudinal support plate 66.

[0045] The opposite movement control assembly includes a longitudinal groove 61, a bidirectional control lead screw 62, a control lead screw nut 64, and a control motor 65. The longitudinal support plate 56 is provided with a longitudinal groove 61, and the bidirectional control lead screw 62 is rotatably connected in the longitudinal groove 61. The longitudinal support plate 56 is provided with a motor mounting groove at a position behind and to the side of the longitudinal groove 61. The rear end of the bidirectional control lead screw 62 extends into the motor mounting groove and is fixedly connected to the output shaft of the control motor 65. The control motor 65 is fixed in the motor mounting groove. The threads of the front and rear ends of the bidirectional control lead screw 62 are in opposite directions. Two control screw nuts 64 are respectively embedded and fixedly connected at the bottom of the two length control vertical rods 63. The two control screw nuts 64 are respectively connected to the front and rear ends of the two-way control screw 62. The control motor 65 drives the two-way control screw 62 to rotate clockwise. The two-way control screw 62 cooperates with the two control screw nuts 64, so that the two control screw nuts 64 drive the two length control vertical rods 63 to approach each other. The control motor 65 drives the two-way control screw 62 to rotate counterclockwise, which can drive the two length control vertical rods 63 away from each other.

[0046] The belt support mechanism 6 also includes a protrusion 611 and a limiting longitudinal groove 612. The outer peripheral side of the intermediate roller 610 is provided with a limiting longitudinal groove 612 along the axial direction. The inner peripheral side of the roller sleeve 69 is provided with a protrusion 611 that is slidably connected to the limiting longitudinal groove 612. The protrusion 611 and the limiting longitudinal groove 612 cooperate with each other to allow the roller sleeve 69 and the intermediate roller 610 to be stably slidably connected.

[0047] The opposite movement control assembly is used to drive the two length control vertical rods 63 to approach or move away from each other, and the two length control vertical rods 63 respectively move the two longitudinal support plates 66. When the two length control vertical rods 63 approach each other, the two roller sleeves 69 gradually move toward the middle of the intermediate roller 610. At this time, the length of the roller formed by the two roller sleeves 69 and the intermediate roller 610 becomes shorter, and the support width of the roller for the conveying belt 23 is reduced, then the effective conveying width of the conveying belt 23 is reduced, and the conveying speed of the coal is reduced when the running speed of the conveying belt 23 is constant. When the length control vertical rods 63 move away from each other, the two roller sleeves 69 move away from each other. At this time, the length of the roller formed by the two roller sleeves 69 and the intermediate roller 610 becomes longer, and the support width of the roller for the conveying belt 23 is increased, then the effective conveying width of the conveying belt 23 is increased, and the conveying speed of the coal is increased when the running speed of the conveying belt 23 is constant.

[0048] The coal transportation thickness adjustment mechanism 7 includes a movable seat 1 71, an adjustment cylinder 72, a movable seat 2 73, a movable block 1 74, an inclined roller 75 and a movable block 2 76. The top of each longitudinal support plate 66 away from the length control vertical rod 63 is fixedly connected with a movable seat 1 71, each movable seat 1 71 is movably connected to the bottom end of the adjustment cylinder 72 through a movable shaft 1, and the top of each adjustment cylinder 72 is fixedly connected with a movable seat 2 73. Each movable seat 2 73 is movably connected to a movable block 1 74 through a movable shaft 2. Each movable block 1 74 is rotationally connected to one end of the inclined roller 75, and the other end of each inclined roller 75 is rotationally connected to a movable block 2 76. Each movable block 2 76 is movably connected to the top of the corresponding length control vertical rod 63 through a movable shaft 3, and the inclined roller 75 is rollingly connected to the lower side of the top side of the conveyor belt 23.

[0049] The coal transportation thickness adjustment mechanism 7 moves with the longitudinal support plate 66 to change the position of the upward folding support for the conveyor belt 23. When the length of the rollers formed by the two roller sleeves 69 and the middle roller 610 increases, since the width of the conveyor belt 23 is fixed, the side width of the conveyor belt 23 that can be folded by the coal transportation thickness adjustment mechanism 7 will decrease. On the contrary, when the length of the rollers formed by the two roller sleeves 69 and the middle roller 610 decreases, the side width of the conveyor belt 23 that can be folded by the coal transportation thickness adjustment mechanism 7 will increase.

[0050] The control adjustment cylinder 72 is extended, and the adjustment cylinder 72 pushes the top of the inclined roller 75 to rise, so that the inclination angle of the inclined roller 75 becomes larger, and the folding angle of the side of the conveying belt 23 increases. At this time, the thickness of the coal that can be conveyed on the conveying belt 23 will become larger, and even if there is thicker coal on the conveying belt 23, it is not easy to fall from the side.

[0051] The control adjustment cylinder 72 is shortened, the inclination angle of the inclined roller 75 is reduced, the folding angle of the side of the conveying belt 23 becomes smaller, and the thickness of the coal that can be conveyed on the conveying belt 23 becomes smaller.

[0052] When in use, the rear end of the left conveying end roller 22 is connected to a power source, which is composed of a motor and a gear box. The power source drives the left conveying end roller 22 to rotate counterclockwise, and the left conveying end roller 22 drives the right conveying end roller 22 to rotate counterclockwise through the transmission of the conveying belt 23. The conveying belt 23 rotates counterclockwise, and the coal falls to the upper right end of the conveying belt 23, and then is transported to the upper left end of the conveying belt 23 as the conveying belt 23 rotates, thereby realizing the transportation of the coal. When a large amount of coal falls to the upper right end of the conveyor belt 23, it will have a certain impact force on the conveyor belt 23. At this time, the impact force of the coal has a downward impact force on the upper support mechanism 6 of the belt through the conveyor belt 23. When the longitudinal support plate 56 is subjected to downward pressure, it drives the column 51 to move downward relative to the horizontal seat plate 1. At this time, as the top of the conveyor belt 23 is concave downward, the column 51 drives the lower support roller 54 to descend through the lower end block 53, so that the lower support roller 54 tightens the bottom of the conveyor belt 23 downward, so that the conveyor belt 23 remains tightened. At this time, the upper spring 55 is compressed and the lower spring 52 The upper spring 55 and the lower spring 52 are stretched, and the impact force caused by the coal on the conveyor belt 23 is buffered. Then, the column 51 is moved upward relative to the horizontal seat plate 1 with the help of the restoring force of the upper spring 55 and the lower spring 52, and the top and bottom of the conveyor belt 23 are gradually restored to a flat state. During this process, the conveyor belt 23 is always kept in a taut state. The belt upper support mechanism 6 is used to support the top inner side of the conveyor belt 23. The coal transportation thickness adjustment mechanism 7 can fold the side of the conveyor belt 23 upward, and the thickness of the coal transported on the conveyor belt 23 can be changed according to the different folding angles.

[0053] For example 2, please refer to Figures 1 to 10 This embodiment provides a technical solution: a safe belt conveyor system. The structure of this embodiment is roughly the same as that of the first embodiment, except that:

[0054] It also includes a dust reduction and dust elimination mechanism 3, which includes an anti-slip baffle 33, a guide inclined plate 35 and an atomizing dust reduction component. Two anti-slip baffles 33 are respectively provided on the front and rear sides of the left end of the left conveying end roller 22, and a guide inclined plate 35 is fixedly connected between the middle parts of the two anti-slip baffles 33. The guide inclined plate 35 is inclinedly arranged with the left side lower and the right side higher, and the right end of the guide inclined plate 35 corresponds to the left middle part of the conveying end roller 22, and an atomizing dust reduction component is installed between the tops of the two anti-slip baffles 33.

[0055] The dust reduction and dust elimination mechanism 3 includes a mounting frame 31 and mounting screws 32. Two mounting frames 31 are respectively arranged on the side away from each other of the two anti-detachment baffles 33. Each mounting frame 31 is fixedly connected to the corresponding support 21 by a mounting screw 32. The anti-detachment baffles 33 are fixedly installed with the help of the mounting frame 31 and the mounting screws 32.

[0056] The atomizing dust suppression component includes a dust suppression longitudinal pipe 34, a solenoid valve 36, a water supply pipe 37, a water pump 38 and a dust suppression atomizing nozzle 39. A dust suppression longitudinal pipe 34 is arranged between the tops of the two anti-slip baffles 33. A dust suppression atomizing nozzle 39 is arranged at an equal distance on the side of the dust suppression longitudinal pipe 34 close to the conveying end roller 22. One end of the dust suppression longitudinal pipe 34 is connected to one end of the water supply pipe 37 through a solenoid valve 36, and the other end of the water supply pipe 37 is connected to the water outlet of the water pump 38. The water pump 38 draws water from an external water source, opens the solenoid valve 36, and the water pump 38 sends water into the dust suppression longitudinal pipe 34 through the water supply pipe 37. The water in the dust suppression longitudinal pipe 34 is sprayed out through the dust suppression atomizing nozzle 39, and the dust raised is reduced by water mist, thereby improving the safety of the site.

[0057] Due to the existence of the conveying end roller 22 on the left side, the conveying belt 23 gradually becomes horizontal when approaching the conveying end roller 22 on the left side. When the coal is conveyed to the left end on the conveying belt 23, it is easy to fall from the front and rear sides of the conveying end roller 22. At this time, the anti-fall-off baffle 33 can block the front and rear sides of the left end of the conveying belt 23, so that the coal on the conveying belt 23 can fall smoothly onto the guiding inclined plate 35, and then slide to the left along the guiding inclined plate 35. Since the coal is easy to raise dust when sliding, an atomizing dust reduction component is provided. The atomizing dust reduction component is used for spraying water by atomizing to avoid raising dust and improve the safety of the transportation site.

[0058] It also includes a cooling mechanism 4, which includes a water supply pipe 2 41, a solenoid valve 2 42, a cooling longitudinal pipe 43 and a cooling spray head 44. A cooling longitudinal pipe 43 is arranged between the bottoms of the two anti-slip baffles 33, and a cooling spray head 44 is arranged at an equal distance on the side of the cooling longitudinal pipe 43 close to the conveying end roller 22. One end of the cooling longitudinal pipe 43 is connected to one end of the water supply pipe 2 41 through the solenoid valve 2 42, and the other end of the water supply pipe 2 41 is connected to the water supply pipe 1 37. Since the conveying belt 23 and the conveying end roller 22 have a large friction force, the conveying belt 23 is prone to high temperature, which has a great safety hazard. If the conveying belt 23 is at a high temperature, the solenoid valve 2 42 is opened, and the water in the water supply pipe 1 37 enters the cooling longitudinal pipe 43 through the water supply pipe 2 41 and the solenoid valve 2 42. The water in the cooling longitudinal pipe 43 is sprayed onto the conveying belt 23 through the cooling spray head 44, which is conducive to cooling the conveying belt 23 and improving the safety during coal transportation.

[0059] For example 3, please refer to Figures 1 to 10This embodiment provides a technical solution: a safe belt conveyor system. The structure of this embodiment is roughly the same as that of the second embodiment, except that:

[0060] It also includes a belt correcting mechanism 9, which includes a mounting support assembly, a rectangular frame 94, a rotating shaft 95, a longitudinal axis 96, a correcting sleeve 97 and a correcting control assembly. A longitudinal rectangular frame 94 is installed on the upper left end of the horizontal seat plate 1 through the mounting support assembly. The middle part of the rectangular frame 94 is movably connected to the middle part of the longitudinal axis 96 through a transverse rotating shaft 95. The front and rear ends of the longitudinal axis 96 are respectively rotatably connected to two correcting sleeves 97, and the bottom of the longitudinal axis 96 is connected to a correcting control assembly.

[0061] The mounting support assembly includes a mounting vertical seat 91, fixing screws 92, and a support rod 93. The mounting vertical seat 91 is provided at the upper left end of the horizontal seat plate 1. The two ends of the mounting vertical seat 91 are fixedly connected to the horizontal seat plate 1 by two fixing screws 92 respectively. The tops of the two ends of the mounting vertical seat 91 are fixedly connected to the bottoms of the two ends of the rectangular frame 94 by two support rods 93 respectively.

[0062] The deviation correction control assembly includes a movable seat 3 98, a deviation correction cylinder 99 and a movable seat 4 910. The bottom of the longitudinal axis 96 is fixedly connected with the movable seat 4 910. The movable seat 4 910 is movably connected to the top of the deviation correction cylinder 99 through the movable shaft 4. The bottom of the deviation correction cylinder 99 is movably connected to the movable seat 3 98 through the movable shaft 5. The movable seat 3 98 is installed on the installation longitudinal seat 91 in the installation support assembly. The movable seat 4 910 is located on the front side of the rotating shaft 95. When the deviation correction cylinder 99 is extended, the longitudinal axis 96 is tilted to a higher front and lower rear position. When the deviation correction cylinder 99 is shortened, the longitudinal axis 96 is tilted to a lower front and higher rear position.

[0063] The conveyor belt 23 is prone to deviate from the conveyor end roller 22 as it runs, so it is necessary to use the belt deviation correction mechanism 9 to correct the conveyor belt 23. When the conveyor belt 23 deviates to the front side relative to the conveyor end roller 22, the deviation correction control component controls the longitudinal axis 96 to move around the rotating shaft 95, so that the longitudinal axis 96 is tilted with the front higher and the back lower. At this time, the deviation correction rotating sleeve 97 at the front end of the longitudinal axis 96 is lifted, and the deviation correction rotating sleeve 97 rolls in contact with the top inner side of the conveyor belt 23. Since the deviation correction rotating sleeve 97 is tilted with the front higher and the back lower, the conveyor belt 23 can be moved backward relative to the conveyor end roller 22 on the left side. When the conveyor belt 23 deviates to the rear side relative to the conveyor end roller 22, the deviation correction control component allows the longitudinal axis 96 to be tilted with the front lower and the back higher, and the deviation correction rotating sleeve 97 at the rear end of the longitudinal axis 96 rolls in contact with the top inner side of the conveyor belt 23, so that the conveyor belt 23 moves forward relative to the conveyor end roller 22 on the left side, thereby gradually correcting the deviation of the conveyor belt 23.

[0064] Example 4, please refer to Figures 1 to 10This embodiment provides a technical solution: a safe belt conveyor system. The structure of this embodiment is roughly the same as that of the third embodiment, except that:

[0065] It also includes a belt edge limiting mechanism 8, which includes a counter-synchronous moving component, an edge limiting ring 85 and an anti-wear ring 86. The two ends of each conveying end roller 22 are respectively connected to two edge limiting rings 85 through the counter-synchronous moving component, and the two edge limiting rings 85 are respectively provided with anti-wear rings 86 on the side where the two edge limiting rings 85 are close to each other, and the outer edge thickness of the anti-wear ring 86 is less than the inner edge thickness.

[0066] The opposite synchronous moving assembly includes a longitudinal adjustment slot 81, a bidirectional adjustment screw 82, a sliding screw nut 83, and a knob 84. The outer peripheral side of each conveying end roller 22 is provided with a longitudinal adjustment slot 81 distributed along the axial direction of the conveying end roller 22. A bidirectional adjustment screw 82 is rotatably connected in the longitudinal adjustment slot 81. The front end of the bidirectional adjustment screw 82 extends to the front side of the conveying end roller 22 and is fixedly connected to the knob 84. The thread directions of the two ends of the bidirectional adjustment screw 82 are opposite. The two ends of the bidirectional adjustment screw 82 are respectively threadedly connected to two sliding screw nuts 83. 3. Both the two sliding screw nuts 83 are longitudinally slidably connected with the corresponding longitudinal adjustment grooves 81, and the two sliding screw nuts 83 are respectively fixedly connected to the inner sides of the two edge limit rings 85. The two-way adjustment screw 82 is rotated clockwise by the knob 84, and the two-way adjustment screw 82 cooperates with the two sliding screw nuts 83 to allow the two sliding screw nuts 83 to drive the two edge limit rings 85 to approach each other synchronously. The two-way adjustment screw 82 is rotated counterclockwise by the knob 84, and the two edge limit rings 85 can be driven to move away from each other synchronously.

[0067] The opposite synchronous moving components can drive the two edge limit rings 85 to move synchronously closer to each other or farther away from each other. The two edge limit rings 85 can allow the two anti-wear rings 86 to move close to the front and rear sides of the conveyor belt 23. The front and rear sides of the conveyor belt 23 are limited by the two anti-wear rings 86 to prevent the conveyor belt 23 from shifting relative to the conveying end roller 22, which is beneficial to the smooth and correct operation of the conveyor belt 23. The anti-wear rings 86 can be made of suitable materials, such as ceramic material, to reduce the wear on the side of the conveyor belt 23.

[0068] For example 5, please refer to Figures 1 to 10 This embodiment provides a technical solution: a safe belt conveyor system. The structure of this embodiment is roughly the same as that of the fourth embodiment, except that:

[0069] It also includes a belt tension adjustment mechanism 10, which includes a tension roller 103 and a tension adjustment component. A longitudinal tension roller 103 is installed at the bottom center of the horizontal seat plate 1 through the tension adjustment component, and the top of the tension roller 103 contacts the lower side of the conveyor belt 23.

[0070] The tension adjustment assembly includes a guide rod 101, an adjustment slider 102, a tightening vertical lead screw 104, a tightening lead screw nut 105, and a hand wheel 106. The front and rear ends of the tightening roller 103 are rotatably connected to two adjustment sliders 102, and two guide rods 101 are slidably connected in the vertical sliding holes on the two adjustment sliders 102. The top ends of the two guide rods 101 are fixedly connected to the bottom of the horizontal seat plate 1, and the side of one of the adjustment sliders 102 is fixedly connected to a tightening lead screw nut 105. The tightening lead screw nut 105 is connected to the vertical tightening vertical lead screw 1 04 is connected with each other, the top of the tightening vertical screw 104 is rotatably connected to the bottom of the horizontal seat plate 1 through a tapered roller bearing, and the bottom of the tightening vertical screw 104 is fixedly connected with a handwheel 106. The tightening vertical screw 104 is rotated clockwise by the handwheel 106, and the threaded action of the tightening vertical screw 104 and the tightening screw nut 105 drives the adjustment slider 102 to move upward along the guide rod 101, thereby driving the tightening roller 103 to move upward, and the tightening vertical screw 104 is rotated counterclockwise by the handwheel 106, which can drive the tightening roller 103 to move downward.

[0071] The tension adjustment component can drive the tensioning roller 103 to move up and down, thereby changing the tension of the conveyor belt 23. When the tension adjustment component drives the tensioning roller 103 to rise, the tensioning roller 103 tightens the conveyor belt 23. When the tension adjustment component drives the tensioning roller 103 to descend, the tensioning roller 103 reduces the tensioning force on the conveyor belt 23.

[0072] It is worth noting that the control motor 65, adjustment cylinder 72, solenoid valve 1 36, water pump 38, solenoid valve 2 42, and correction cylinder 99 disclosed in the above embodiments are all controlled by an external PLC controller, and the control method adopts the method commonly used in the prior art, wherein the control motor 65 adopts a servo motor, and the adjustment cylinder 72 and the correction cylinder 99 are connected to an external air pressure source through an air pipe.
