Description

Technical Field

[0001] The present invention relates to the technical field of coal transportation, and in particular to a transportation device for coal production and processing. Background Art

[0002] In the transportation link of coal production and processing, the uniform distribution of coal on the conveyor belt is the key to ensuring the efficient operation of subsequent processes. However, due to factors such as the coal's own particle characteristics, the conveyor belt's running speed and uneven load, coal is very likely to accumulate during transportation. This accumulation will not only cause the coal to spill during transportation, resulting in material waste, but also make the coal too thick or too thin in some areas on the conveyor belt, directly affecting the stability of subsequent screening, washing, combustion and other processes. For example, accumulated coal will make it difficult for screening equipment to accurately separate impurities, reducing screening efficiency; in combustion scenarios, unevenly distributed coal will lead to unstable calorific value release, affecting combustion efficiency and energy utilization.

[0003] At present, although most coal transportation equipment is equipped with vibration devices to improve the coal distribution problem, a fixed vibration mode is generally used. This mode has significant defects: when the amount of coal piled is large, the fixed amplitude vibration intensity is insufficient, and the accumulated coal cannot be quickly dispersed, making it difficult to meet the needs of efficient operation; and when the amount of coal transported is small, the equipment still vibrates at a fixed intensity, which will cause energy waste. In addition, the existing equipment lacks the ability to adaptively adjust the change in coal quantity, and cannot dynamically adjust the vibration amplitude according to the real-time coal quantity. If it relies on manual monitoring and adjustment, it will increase labor costs, which is contrary to the trend of industrial automation production. Summary of the invention

[0004] In view of the problem of the prior art that the existing equipment lacks the ability to adaptively adjust the change of coal quantity and cannot dynamically adjust the vibration amplitude according to the real-time coal quantity, a conveying equipment for coal production and processing is proposed.

[0005] Its purpose is: when the amount of coal increases, the device automatically increases the vibration amplitude to quickly and evenly spread the accumulated coal; when the amount of coal is small, maintain a reasonable vibration intensity to avoid energy waste.

[0006] The technical solution of the present invention is a conveying device for coal production and processing, comprising a conveyor belt, a driving roller arranged on one side of the conveyor belt, a plurality of support frames arranged in the middle of the conveyor belt, a mounting plate arranged in the middle of the support frame, and a plurality of transmission rollers arranged on the top of the support frame and distributed in a V shape. The conveyor belt drives the transmission rollers to rotate through friction, and also comprises driving components arranged on both sides of the middle transmission roller, and two vibrating components arranged in the middle of the two driving components. The driving component is used to drive the vibrating component to vibrate the conveyor belt; The vibration component includes a vibration assembly arranged on the top of the mounting plate, and an amplitude switching assembly arranged on the vibration assembly; The vibration assembly includes a side plate arranged on the top of the mounting plate, a rotating rod arranged on the side plate, a protrusion 1 arranged on the rotating rod, an arched plate arranged on the top of the mounting plate, a vibration rod arranged on the arched plate, a fixed rod arranged on one side of the vibration rod, a lifting wheel arranged on one side of the fixed rod, a protrusion 1 abutting against the lifting wheel, a vibration plate arranged on the top of the two vibration rods, and a reset assembly arranged between the vibration rod and the arched plate.

[0007] Furthermore, the reset assembly includes a reset spring arranged inside the arch plate, a circular rod arranged on the top of the reset spring, and the top of the circular rod is fixedly connected to the vibration rod, and the vibration rod slides in the arch plate through limit blocks on both sides.

[0008] Furthermore, the driving component includes a connecting rod arranged in the middle transmission roller, a driving wheel arranged on one side of the connecting rod, a belt arranged on the driving wheel, and a driven wheel arranged on one side of the belt, and the driven wheel is fixedly connected to the rotating rod.

[0009] Furthermore, the amplitude switching component includes a protrusion 2 arranged on one side of the protrusion 1, switching inclined surfaces opened on both sides of the protrusion 1, baffles symmetrically arranged on the sides of the two protrusions, a limit bar arranged in the middle of the protrusion 1 and the protrusion 2, and the limit bar is limited and slid on the rotating rod, a switching spring arranged on the other side of the protrusion 1, and a circular plate arranged on one side of the switching spring, the circular plate is fixedly connected to the rotating rod, and the protrusion 1 and the protrusion 2 are elliptical.

[0010] Furthermore, the first and second protrusions are arranged in a "cross" shape, and the switching slopes are arranged on the two sides of the largest diameter of the first protrusion.

[0011] Furthermore, the connecting distance between two points at the maximum diameter of the first bump is greater than the connecting distance between two points at the minimum diameter of the second bump, and the connecting distance between two points at the maximum diameter of the first bump is less than the connecting distance between two points at the maximum diameter of the second bump.

[0012] Furthermore, both sides of the second protrusion with a wider diameter are provided with strip-shaped protrusions.

[0013] Furthermore, the vibration plate is in a U-shape matching the conveyor belt, and vibration bars are evenly arranged on the vibration plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The vibration components can optimize the uniformity of coal. Continuous vibration can break the coal accumulation state and make the coal spread evenly on the conveyor belt. Especially when the amount of coal is large, the enhanced vibration can quickly disperse the accumulated coal to avoid local excessive thickness or thinness, ensure the stability of subsequent screening, washing, combustion and other processes, and improve the overall processing efficiency.

[0015] 2. The second convex block has a larger rotation range, which makes the vibration rod lifted to a greater extent, and the vibration amplitude of the conveyor belt is larger, so as to achieve rapid vibration and even spreading of coal in places where there are more coal piles. The device automatically adjusts the vibration amplitude according to the amount of coal. The greater the amount of coal, the stronger the vibration, forming a "dynamic response" mechanism. This targeted operation can not only efficiently handle the accumulated coal, but also avoid energy waste in the fixed vibration mode, maximizing the dispersion effect while saving energy.

[0016] 3. The vibration strips on the vibration plate are used to squeeze and vibrate the bottom and side walls of the conveyor belt, so that all parts of the conveyor belt can be vibrated, speeding up the uniform distribution of the accumulated coal. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0020] Example 1, reference Figure 1-Figure 11 , which is the first embodiment of the present invention, provides a conveying equipment for coal production and processing, including a conveyor belt 1, a driving roller 11 installed on one side of the conveyor belt 1, a plurality of support frames 12 installed in the middle of the conveyor belt 1, a mounting plate 13 installed in the middle of the support frame 12, and a plurality of V-shaped transmission rollers 14 installed on the top of the support frame 12. The conveyor belt 1 drives the transmission rollers 14 to rotate through friction under the gravity of the coal, and also includes a driving component 4 installed on both sides of the middle transmission roller 14, and two vibrating components installed in the middle of the two driving components 4; the driving component 4 is used to drive the vibrating component to vibrate the conveyor belt 1; the vibrating component includes a vibrating component installed on the top of the mounting plate 13 The vibration component 2 includes a side plate 21 fixedly connected to the top of the mounting plate 13, a rotating rod 22 rotatably connected to the side plate 21, a protrusion 23 limitedly slidably connected to the rotating rod 22, an arched plate 24 fixedly connected to the top of the mounting plate 13, a vibration rod 25 limitedly slidably connected in the arched plate 24, a fixed rod 26 fixedly connected to one side of the vibration rod 25, a lifting wheel 27 rotatably connected to one side of the fixed rod 26, a protrusion 23 abutting against the lifting wheel 27, a vibration plate 28 fixedly connected to the top of the two vibration rods 25, and a reset component 3 installed between the vibration rod 25 and the arched plate 24.

[0021] Specifically, when conveying coal, the driving roller 11 is driven by the motor to rotate, thereby driving the conveyor belt 1 to rotate, and the coal on the conveyor belt 1 squeezes the conveyor belt 1, so that the conveyor belt 1 drives the transmission roller 14 to rotate, and the transmission roller 14 drives the driving component 4 to rotate after the rotation, and the driving component 4 drives the vibration component to vibrate, so that the coal on the conveyor belt 1 is vibrated evenly to avoid coal accumulation. After the rotating rod 22 is driven to rotate by the driving component 4, the rotating rod 22 drives the protrusion 23 to rotate, and when the protrusion 23 rotates, it pushes the top lifting wheel 27 to move up and down, and the lifting wheel 27 moves up and down, so that the vibration plate 28 continuously hits the conveyor belt 1, realizes the vibration of the coal on the conveyor belt 1, and makes it evenly distributed on the conveyor belt 1, so as to avoid the coal from accumulating somewhere on the conveyor belt 1, causing the coal to fall during the transportation process. The uniformity of the coal can be optimized, and the coal accumulation state can be broken by continuous vibration, so that the coal can be evenly spread on the conveyor belt 1. Especially when the amount of coal is large, enhanced vibration can quickly disperse the accumulated coal and avoid local excessive thickness or thinness, ensuring the stability of subsequent screening, washing, combustion and other processes and improving overall processing efficiency.

[0022] Reference Figure 1-Figure 6 The reset assembly 3 includes a reset spring 31 fixedly connected to the inside of the arch plate 24, a circular rod 32 fixedly connected to the top of the reset spring 31, and the top of the circular rod 32 is fixedly connected to the vibration rod 25, and the vibration rod 25 is limited and slidable in the arch plate 24 by the limit blocks on both sides.

[0023] Specifically, when the protrusion 23 pushes the lifting wheel 27 and the vibration rod 25 to move upward, the reset spring 31 is stretched. The reset spring 31 is used to enable the vibration rod 25 to reset and move downward after being pushed upward, thereby achieving a continuous striking vibration effect. The vibration rod 25 is limitedly slid in the arch plate 24, which can improve its stability during vibration.

[0024] Reference Figure 1-Figure 4 and Fig.11 The driving component 4 includes a connecting rod 41 fixedly connected to the middle transmission roller 14, a driving wheel 42 fixedly connected to one side of the connecting rod 41, a belt 43 transmission-connected to the driving wheel 42, and a driven wheel 44 transmission-connected to one side of the belt 43, and the driven wheel 44 is fixedly connected to the rotating rod 22.

[0025] Specifically, when the transmission roller 14 rotates, the connecting rod 41 and the driving wheel 42 are driven to rotate, and the driven wheel 44 is driven to rotate by the belt 43. The coal on the belt 43 squeezes the belt 43, so that the belt 43 drives the transmission roller 14 to rotate, thereby realizing power transmission. No additional power is required, the structure is simple, and the cost is low. Moreover, when there is more coal, its gravity is greater, so that the power transmission effect of the transmission roller 14 to the driving wheel 42 is better, thereby making the vibration effect better. It has a positive feedback adjustment function, so that the coal is distributed more evenly, avoiding the accumulation of coal in a certain place, resulting in greater squeezing force and greater wear between the conveyor belt 1 and the transmission roller 14, and effectively improving the service life of the conveyor belt 1.

[0026] Example 2, reference Figure 1-Figure 7 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the amplitude switching component 5 includes a second protrusion 51 fixedly connected to one side of the protrusion 23, switching inclined surfaces 52 provided on both sides of the protrusion 23, baffles 53 symmetrically fixedly connected to the sides of the second protrusion 51, a limiting strip 54 fixedly connected to the protrusion 23 and the middle of the second protrusion 51, and the limiting strip 54 is limited to slide on the rotating rod 22, a switching spring 55 abutting on the other side of the protrusion 23, a circular plate 56 fixedly connected to one side of the switching spring 55, and the circular plate 56 is fixedly connected to the rotating rod 22. The protrusion 23 and the second protrusion 51 are elliptical.

[0027] Specifically, when there is more coal at a certain place on the conveyor belt 1, since there is a certain distance between two adjacent driving rollers 14, the conveyor belt 1 located between the adjacent driving rollers 14 will be squeezed by the coal and will become concave. The more coal there is, the larger the depression will be, and the squeezing and moving distance of the vibration plate 28 will be greater, so that when the lifting wheel 27 rotates on the protrusion 23 to the switching slope 52, it will slide along the switching slope 52 to the protrusion 2 51. At this time, the protrusion 1 23 is squeezed and moved, and the protrusion 1 23 compresses the switching spring 55. The rotation of the protrusion 2 51 continues to drive the lifting wheel 27 to rotate. At this time, the rotation range of the protrusion 2 51 is larger, so that the vibration rod 25 is lifted to a greater extent, and the vibration amplitude of the conveyor belt 1 is larger, thereby realizing rapid vibration and even spreading of the coal at the places where it is accumulated more. The device automatically adjusts the vibration amplitude according to the amount of coal. The larger the amount of coal, the stronger the vibration, forming a "dynamic response" mechanism. This targeted operation can not only efficiently process the accumulated coal, but also avoid energy waste in the fixed vibration mode, maximizing the dispersion effect while saving energy, without the need for manual real-time monitoring of the coal volume and adjustment of the equipment, reducing manpower input, meeting the needs of industrial automation production, and improving the overall intelligent level of the operation. The setting of the baffle 53 ensures that the lifting wheel 27 will not easily break away from the protrusion 1 23 when entering the protrusion 2 51. When the coal accumulation is evenly distributed by vibration, the protrusion 1 23 and the protrusion 2 51 are reset, so that the lifting wheel 27 can only be moved out from the switching slope 52, avoiding the lifting wheel 27 from directly moving out from the protrusion 2 51 with a larger diameter, causing the vibration rod 25 to move down suddenly, so that the conveyor belt 1 drives the coal to fall directly for a distance, avoiding unstable vibration of the conveyor belt 1.

[0028] Reference Figure 8-Figure 10 The first protrusion 23 and the second protrusion 51 are arranged in a "cross" shape, and the switching slope 52 is arranged on both sides of the largest diameter of the first protrusion 23.

[0029] Specifically, the "cross" cross design allows the vibration amplitude to be greatly improved, and the switching slope 52 is designed to achieve the switching of the amplitude.

[0030] Reference Figure 9-10 , the connecting distance between the two points at the maximum diameter of the bump 1 23 is greater than the connecting distance between the two points at the minimum diameter of the bump 2 51, and the connecting distance between the two points at the maximum diameter of the bump 1 23 is less than the connecting distance between the two points at the maximum diameter of the bump 2 51.

[0031] Specifically, the connecting distance between the two points where the diameter of the bump 1 23 is the largest is greater than the connecting distance between the two points where the diameter of the bump 2 51 is the smallest, so that the lifting wheel 27 can move along the switching slope 52 to the bump 2 51, and the connecting distance between the two points where the diameter of the bump 1 23 is the largest is less than the connecting distance between the two points where the diameter of the bump 2 51 is the largest, so that the vibration amplitude of the bump 2 51 when it is lifted is larger.

[0032] Reference Fig. 9 , strip-shaped protrusions 6 are evenly distributed on both sides of the wider diameter of the second protrusion 51.

[0033] Specifically, the arrangement of the strip-shaped protrusions 6 increases the amplitude of vibration when the protrusion 2 51 is driving the vibration, thereby improving the vibration effect and further accelerating the uniform distribution of the deposited coal.

[0034] Reference Figure 4 The vibration plate 28 is in a U-shape matching the conveyor belt 1 , and the vibration bars 7 are evenly and fixedly connected to the vibration plate 28 .

[0035] Specifically, the vibration strips 7 on the vibration plate 28 are used to perform extrusion vibration on the bottom and side walls of the conveyor belt 1, so that all parts of the conveyor belt 1 can be vibrated, thereby accelerating the speed of uniform distribution of the accumulated coal. The remaining structure is the same as that of the first embodiment.

[0036] Based on the embodiments 1-2, the working principle of the present invention is as follows: when transporting coal, the driving roller 11 is driven to rotate by the motor, thereby driving the conveyor belt 1 to rotate, and the coal on the conveyor belt 1 squeezes the conveyor belt 1, so that the conveyor belt 1 drives the transmission roller 14 to rotate, and the transmission roller 14 drives the driving component 4 to rotate after the rotation, and the driving component 4 drives the vibration component to vibrate, so that the coal on the conveyor belt 1 is vibrated evenly to avoid coal accumulation. After the rotating rod 22 is driven to rotate by the driving component 4, the rotating rod 22 drives the protrusion 1 23 to rotate, and when the protrusion 1 23 rotates, it pushes the top lifting wheel 27 to move up and down, and the lifting wheel 27 moves up and down, so that the vibration plate 28 continuously hits the conveyor belt 1, realizes the vibration of the coal on the conveyor belt 1, and evenly distributes it on the conveyor belt 1, and avoids the coal from accumulating somewhere on the conveyor belt 1, causing the coal to spill during the transportation process. The uniformity of the coal can be optimized, and the coal accumulation state can be broken by continuous vibration, so that the coal can be evenly spread on the conveyor belt 1. Especially when the amount of coal is large, enhanced vibration can quickly disperse the accumulated coal and avoid local excessive thickness or thinness, ensuring the stability of subsequent screening, washing, combustion and other processes and improving overall processing efficiency.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
