Description

Technical Field

[0001] This utility model relates to the field of coal production technology, and in particular to a weighing and measuring device for coal production. Background Technology

[0002] During coal transportation, coal is placed on a conveyor belt, which moves along with it as the belt operates. A weighing mechanism located below the conveyor belt measures the weight of the coal, thus enabling real-time weighing during transportation and ensuring timely control of coal weight throughout the process.

[0003] In coal weight detection, when using a load cell, it needs to be installed below the conveyor belt so that the load cell can sense the pressure generated by the conveyor belt and the coal placed on the conveyor belt. The pressure acts on the piezoelectric sensor, causing it to generate an electric charge signal. Then, the electric charge signal is processed by relevant components to obtain the weight data of the coal.

[0004] During installation, poor contact between the sensor and the conveyor belt can lead to unstable pressure transmission, directly affecting the accuracy of the detection signal. Fixing the sensor is a very complicated process, requiring reinforcement with multiple components. The operation steps are complex, and incorrect installation can cause uneven stress on the sensor, reducing the accuracy of weight detection. Furthermore, the position needs to be readjusted, which consumes additional time and manpower, affecting detection efficiency and overall work progress. Utility Model Content

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 4 An embodiment of this utility model provides a weighing device for coal production, comprising a housing 1, with connecting shells 2 fixedly connected to both the left and right sides of the housing 1, a weighing mechanism 3 provided on the bottom inside the housing 1 for recording weight, a fixing mechanism 4 provided inside each of the two connecting shells 2 for convenient fixing, a sealing mechanism 5 provided on the rear side of the housing 1, a support mechanism 6 provided on the bottom inside the housing 1, a vibration mechanism 7 provided on the top of the support mechanism 6, and a rotation mechanism 8 provided on the top of the vibration mechanism 7.

[0035] The weighing mechanism 3 includes a base plate 31, the bottom of which is fixedly connected to the bottom of the box 1. Springs 32 are fixedly connected to the four corners of the top of the base plate 31. A weighing sensor 33 is fixedly connected to the center of the top of the base plate 31. The tops of multiple springs 32 are fixedly connected to the same top plate 34. A data processing component 35 is provided on the front left side of the box 1.

[0036] Specifically, when coal is conveyed to the rotating mechanism 8, the rotating mechanism 8 can transfer the coal so that it can be evenly distributed. Through the operation of the rotating mechanism 8, the position of the coal on the top of the vibrating mechanism 7 can be adjusted, which facilitates the subsequent weighing operation. The vibrating mechanism 7 is started under the support of the support mechanism 6. The vibration of the vibrating mechanism 7 is transmitted to the rotating mechanism 8 through its connection with the rotating mechanism 8, so that the coal on the rotating mechanism 8 is further spread out under the vibration, avoiding coal accumulation and affecting the weighing accuracy. The bottom of the support mechanism 6 is connected to the bottom of the box 1, and the top of the support mechanism 6 is connected to the vibrating mechanism 7. Through the stable support of the support mechanism 6, the vibrating mechanism 7 is ensured to maintain a stable posture during operation, ensuring the effective transmission of the vibration effect.

[0037] After the coal is placed on the rotating mechanism 8 and vibrated by the vibration mechanism 7, the weight of the coal is transmitted sequentially through the rotating mechanism 8 and the vibration mechanism 7 to the support mechanism 6, and then from the support mechanism 6 to the top plate 34. Upon receiving the weight, the top plate 34 will shift downwards, compressing the spring 32 connected to the bottom of the top plate 34. The spring 32, through its elastic deformation, acts as a buffer for the top plate 34. The bottom of the top plate 34 contacts the weighing sensor 33. When the weighing sensor 33 is subjected to pressure, it converts the weight signal into an electrical signal, which is then transmitted to the data processing component. 35. The data processing component 35 processes the electrical signal to obtain the weight data of the coal, thereby realizing the measurement of the coal. The fixing mechanism 4 is set inside the connecting shell 2, which is fixedly connected to the left and right sides of the box 1. Through the action of the fixing mechanism 4, the entire device can be conveniently fixed in the required position to ensure that the device will not be displaced during operation and to ensure the stability of the weighing operation. The sealing mechanism 5 is set on the rear side of the box 1. The sealing mechanism 5 can seal the rear side of the box 1 to prevent external debris from entering the interior of the box 1 and affecting the normal operation of each mechanism.

[0038] Reference Figure 4 , Figure 5 and Figure 6 The fixing mechanism 4 includes multiple clamping pieces 41. The outer walls of the multiple clamping pieces 41 are slidably connected to the front ends of the left and right sides inside the two connecting shells 2. The rear sides of the multiple clamping pieces 41 are fixedly connected to trapezoidal push blocks 42. The interior of the multiple trapezoidal push blocks 42 is provided with sliding grooves 43. The interior of the multiple sliding grooves 43 is slidably connected to pulleys 44. The outer walls of the multiple pulleys 44 are slidably connected to sliders 45. The rear sides of the two sliders 45 are provided with pushing components 46.

[0039] Specifically, when it is necessary to fix the equipment, the push component 46 is activated, which drives the slider 45 to move forward. The movement of the slider 45 causes the pulley 44 to slide on the outer wall of the slider 45. At the same time, the pulley 44 slides inside the slide groove 43. Through the sliding of the pulley 44 on the slide groove 43 and the slider 45, the trapezoidal push block 42 is subjected to a horizontal pushing force. After the trapezoidal push block 42 is subjected to the force, it drives the clamping piece 41 to slide on the left and right front ends inside the connecting shell 2.

[0040] As the pushing component 46 continuously pushes the slider 45, the slider 45 further applies force to the trapezoidal push block 42 via the pulley 44. The trapezoidal push block 42 drives the clamping plate 41 to move closer to the fixed position of the equipment. Through the movement of the clamping plate 41, the clamping plate 41 contacts the fixed position and generates a clamping force. After the clamping plate 41 is in close contact with the fixed position, the pushing component 46 stops working, the slider 45 maintains its current position, the pulley 44 is fixed in position on the slide groove 43 and the slider 45, the trapezoidal push block 42 no longer moves, and the clamping plate 41 maintains the clamping state. By clamping the fixed position with the clamping plate 41, the equipment is fixed. When it is necessary to release the fixation, the pushing component 46 operates in the reverse direction, bringing... The movable slider 45 moves backward, causing the pulley 44 to slide in the opposite direction on the slide groove 43 and the slider 45. The trapezoidal push block 42 is subjected to a reverse force, which drives the clamping piece 41 to slide away from the fixed position. Through the reverse movement of the clamping piece 41, the clamping piece 41 separates from the fixed position, releasing the fixation of the equipment. By driving the push component 46 and moving the slider 45, the pulley 44 is driven to slide on the slide groove 43 and the slider 45, causing the trapezoidal push block 42 to drive the clamping piece 41 to slide within the connecting shell 2, thereby achieving the fixation and release of the equipment. Through the clamping and releasing of the clamping piece 41, the equipment is ensured to remain stable during operation and can be easily released when it needs to be moved.

[0041] Reference Figure 2 , Figure 3 and Figure 4 The data processing component 35 includes an inclined connecting rod 351, the rear side of which is fixedly connected to the front left end of the housing 1. The top of the inclined connecting rod 351 is fixedly connected to a housing 352. The front side of the inner interior of the housing 352 is fixedly connected to a display screen 353. The pushing component 46 includes a nut 461, the outer wall of which is fixedly connected to the middle of the rear side of the connecting shell 2. The nut 461 is threadedly connected to a threaded rod 462. The front side of the threaded rod 462 is threadedly connected to a bearing 463. The outer wall of the bearing 463 is rotatably connected to an annular shell 464. The upper and lower rear ends of the annular shell 464 are both fixedly connected to telescopic rods 465.

[0042] Specifically, in the data processing component 35, the rear side of the inclined connecting rod 351 is fixedly connected to the front left end of the housing 1, the outer shell 352 is fixedly connected to the top of the inclined connecting rod 351, and the display screen 353 is fixedly connected to the front inside of the outer shell 352. The weighing sensor 33 transmits the weight signal to the data processing component 35. After the data processing component 35 processes the signal, the processing result is displayed on the display screen 353. Through the signal processing of the data processing component 35 and the information display of the display screen 353, the visual presentation of the weighing data is realized.

[0043] When the push assembly 46 is running, the outer wall of the nut 461 is fixedly connected to the middle of the rear side of the connecting shell 2. The threaded rod 462 is threadedly connected to the inside of the nut 461. When the threaded rod 462 is rotated, the threaded rod 462 undergoes threaded transmission within the nut 461. The front side of the threaded rod 462 is threadedly connected to the bearing 463. The outer wall of the bearing 463 is rotatably connected to the annular shell 464. The rotation of the threaded rod 462 drives the bearing 463 to rotate within the annular shell 464. At the same time, the threaded rod 462 pushes the bearing 463 to move forward. The bearing 463 drives the annular shell 464 to move forward. The upper and lower ends of the rear side of the annular shell 464 are fixedly connected to telescopic rods 465. When the annular shell 464 moves, the telescopic rods 465 extend and retract accordingly. Through the threaded engagement between the threaded rod 462 and the nut 461, and the rotatable connection between the bearing 463 and the annular shell 464, the smooth movement of the annular shell 464 is achieved.

[0044] When the annular shell 464 needs to be moved in the reverse direction, the threaded rod 462 is rotated in the reverse direction. The threaded rod 462 is driven by the reverse thread within the nut 461, which drives the bearing 463 to move backward. The bearing 463 drives the annular shell 464 to move backward. The telescopic rod 465 extends and retracts in the reverse direction as the annular shell 464 moves. The movement of the annular shell 464 drives the slider 45 to move, thereby achieving the clamping and releasing of the clamping plate 41. Through the reverse rotation of the threaded rod 462 and the reverse extension and retraction of the telescopic rod 465, the reverse movement of the annular shell 464 is achieved, thus completing the release of the equipment from its fixed state.

[0045] Reference Figure 1 , Figure 3 and Figure 4The sealing mechanism 5 includes a sealing shell 51, the front side of which is fixedly connected to the rear side of the housing 1. A push plate 52 is slidably connected to the left side of the sealing shell 51. The support mechanism 6 includes a vertical rod 61, the bottom of which is fixedly connected to the bottom inner side of the housing 1. A recessed platform 62 is fixedly connected to the top of the vertical rod 61. The vibration mechanism 7 includes a balance block 71, the bottom side of which has a recessed platform 62. The left side of the balance block 71 is fixedly connected to... The device includes a plumb bob 72, a conical pressure block 73 at the top center of the balance block 71, a plate 74 fixedly connected to the top of the conical pressure block 73, and a rotating mechanism 8 including multiple support rods 81. The multiple support rods 81 are respectively arranged on the front and rear sides of the box body 1. The top of each of the multiple support rods 81 is fixedly connected to a concave rod 82. The outer walls of the multiple concave rods 82 are rotatably connected to multiple rotating wheels 83. The outer walls of the multiple rotating wheels 83 are slidably connected to the same conveyor belt 84.

[0046] Specifically, in the sealing mechanism 5, the front side of the sealing shell 51 is fixedly connected to the rear side of the box 1, and the push plate 52 is slidably connected to the left side of the sealing shell 51. The sliding push plate 52 can change the closed state of the internal space of the sealing shell 51. By sliding the push plate 52 on the sealing shell 51 and the fixed connection of the sealing shell 51 to the rear side of the box 1, the sealing control of the rear side of the box 1 can be achieved.

[0047] When the support mechanism 6 is running, the bottom of the upright 61 is fixedly connected to the bottom of the inner side of the box 1, and the recessed platform 62 is fixedly connected to the top of the upright 61. Through the support of the upright 61 to the recessed platform 62 and the fixation of the upright 61 to the bottom of the inner side of the box 1, the vibration mechanism 7 is stably supported.

[0048] In the vibration mechanism 7, the bottom center of the balance block 71 contacts the recessed platform 62, the plumb bob 72 is fixedly connected to the left side of the balance block 71, the conical pressure block 73 is set at the top center of the balance block 71, and the plate 74 is fixedly connected to the top of the conical pressure block 73. When the balance block 71 vibrates on the recessed platform 62, the plumb bob 72 moves synchronously with the balance block 71 to maintain the stability of the balance block 71. The conical pressure block 73 transmits the vibration of the balance block 71 to the plate 74. Through the contact and cooperation between the balance block 71 and the recessed platform 62 and the balancing effect of the plumb bob 72 on the balance block 71, the stable transmission of vibration is achieved.

[0049] When the rotating mechanism 8 is running, multiple support rods 81 are respectively arranged on the front and rear sides of the housing 1. The concave rod 82 is fixedly connected to the top of the support rod 81. The rotating wheel 83 is rotatably connected to the outer wall of the concave rod 82. The conveyor belt 84 is slidably connected to the outer wall of the multiple rotating wheels 83. The rotating wheel 83 rotates on the concave rod 82, driving the conveyor belt 84 to slide on the outer wall of the multiple rotating wheels 83. Through the rotation of the rotating wheel 83 on the concave rod 82 and the sliding connection between the conveyor belt 84 and the rotating wheel 83, the coal is transported.

[0050] Working principle: When coal is conveyed to the rotating mechanism 8, the rotating mechanism 8 operates. Multiple support rods 81 are respectively set on the front and rear sides of the box 1. The concave rod 82 is fixedly connected to the top of the support rod 81. The rotating wheel 83 is rotatably connected to the outer wall of the concave rod 82. The conveyor belt 84 is slidably connected to the outer wall of the multiple rotating wheels 83. The rotating wheel 83 rotates on the concave rod 82, driving the conveyor belt 84 to slide on the outer wall of the multiple rotating wheels 83. Through the rotation of the rotating wheel 83 on the concave rod 82 and the sliding connection between the conveyor belt 84 and the rotating wheel 83, the coal is conveyed and the coal can be evenly distributed. Through the operation of the rotating mechanism 8, the position of the coal can be adjusted on the top of the vibrating mechanism 7, which provides convenience for subsequent weighing operations.

[0051] The vibration mechanism 7 is activated under the support of the support mechanism 6. When the support mechanism 6 is running, the bottom of the upright 61 is fixedly connected to the bottom of the inner side of the housing 1, and the recessed platform 62 is fixedly connected to the top of the upright 61. Through the support of the upright 61 on the recessed platform 62 and the fixation of the upright 61 on the bottom of the inner side of the housing 1, the vibration mechanism 7 is stably supported. In the vibration mechanism 7, the bottom center of the balance block 71 is in contact with the recessed platform 62, the plumb bob 72 is fixedly connected to the left side of the balance block 71, the conical pressure block 73 is set at the top center of the balance block 71, and the plate 74 is fixedly connected to the top of the conical pressure block 73. When the balance block 71 vibrates on the recessed platform 62, the plumb bob 72 moves synchronously with the balance block 71 to maintain balance. The stability of block 71 is achieved by the conical pressure block 73 transmitting the vibration of the balance block 71 to the plate 74. Through the contact and cooperation between the balance block 71 and the concave platform 62 and the balancing effect of the plumb bob 72 on the balance block 71, the vibration is stably transmitted. The vibration of the vibration mechanism 7 is transmitted to the rotating mechanism 8 through the connection between the vibration mechanism 7 and the rotating mechanism 8. The coal on the rotating mechanism 8 is further spread out under the action of vibration, avoiding coal accumulation that affects the weighing accuracy. The bottom of the support mechanism 6 is connected to the bottom side of the inside of the box 1, and the top of the support mechanism 6 is connected to the vibration mechanism 7. Through the stable support of the support mechanism 6 for the vibration mechanism 7, the vibration mechanism 7 is ensured to maintain a stable posture during operation, ensuring the effective transmission of the vibration effect.

[0052] After the coal is placed on the rotating mechanism 8 and vibrated by the vibration mechanism 7, its weight is transmitted sequentially through the rotating mechanism 8 and the vibration mechanism 7 to the support mechanism 6, and then from the support mechanism 6 to the top plate 34. Upon receiving the weight, the top plate 34 will shift downwards, compressing the spring 32 connected to the bottom of the top plate 34. The spring 32, through its elastic deformation, acts as a buffer for the top plate 34. The bottom of the top plate 34 contacts the weighing sensor 33. When the weighing sensor 33 is subjected to pressure, it converts the weight signal into an electrical signal, which is then transmitted to the data processing component 35. In the weighing component 35, the rear side of the inclined connecting rod 351 is fixedly connected to the front left end of the housing 1, and the outer shell 352 is fixedly connected to the top of the inclined connecting rod 351. The display screen 353 is fixedly connected to the front side of the inner side of the outer shell 352. The weighing sensor 33 transmits the weight signal to the data processing component 35. After the data processing component 35 processes the signal, the processing result is displayed on the display screen 353. Through the signal processing of the data processing component 35 and the information display of the display screen 353, the visual presentation of the weighing data is realized, thereby obtaining the weight data of the coal and realizing the measurement of the coal.

[0053] The fixing mechanism 4 is located inside the connecting shell 2, which is fixedly connected to the left and right sides of the housing 1. Through the action of the fixing mechanism 4, the entire device can be easily fixed in the required position, ensuring that the device will not shift during operation and guaranteeing the stability of the weighing work. When the device needs to be fixed, the push assembly 46 is activated. The outer wall of the nut 461 is fixedly connected to the middle of the rear side of the connecting shell 2. The threaded rod 462 is threadedly connected to the inside of the nut 461. Rotating the threaded rod 462 causes threaded transmission within the nut 461. The front side of the threaded rod 462 is threadedly connected to the bearing 463. The outer wall of the bearing 463 is rotatably connected to the annular shell 464. The rotation of the threaded rod 462 drives the bearing 463 to rotate within the annular shell 464, while simultaneously pushing the threaded rod 462... The bearing 463 moves forward, which drives the annular shell 464 to move forward. The upper and lower ends of the rear side of the annular shell 464 are fixedly connected to the telescopic rod 465. When the annular shell 464 moves, the telescopic rod 465 extends and retracts accordingly. Through the threaded engagement of the threaded rod 462 and the nut 461, and the rotational connection between the bearing 463 and the annular shell 464, the smooth movement of the annular shell 464 is achieved. The push assembly 46 drives the slider 45 to move forward. The movement of the slider 45 drives the pulley 44 to slide on the outer wall of the slider 45. At the same time, the pulley 44 slides inside the groove 43. Through the sliding of the pulley 44 on the groove 43 and the slider 45, the trapezoidal push block 42 is subjected to a horizontal thrust. After the trapezoidal push block 42 is subjected to the force, it drives the clamping piece 41 to slide on the left and right front ends inside the connecting shell 2.

[0054] The pushing component 46 continuously pushes the slider 45. The slider 45 further applies force to the trapezoidal push block 42 through the pulley 44. The trapezoidal push block 42 drives the clamping plate 41 to move closer to the fixed position of the equipment. Through the movement of the clamping plate 41, the clamping plate 41 contacts the fixed position and generates a clamping force. After the clamping plate 41 is in close contact with the fixed position, the pushing component 46 stops working, the slider 45 remains in its current position, the pulley 44 is fixed in its position on the slide groove 43 and the slider 45, the trapezoidal push block 42 no longer moves, and the clamping plate 41 maintains the clamping state. The equipment is fixed by clamping the fixed position with the clamping plate 41. When it is necessary to release the fixation, the pushing component 46 operates in reverse, rotating the threaded rod 462 in the reverse direction. The threaded rod 462 drives the bearing 463 to move backward in the reverse thread transmission within the nut 461. The bearing 463 drives the annular shell 464 to move backward, and the telescopic rod 465 extends and retracts in the opposite direction with the movement of the annular shell 464. The slider 45 is moved to clamp and release the clamping plate 41. The reverse rotation of the threaded rod 462 and the reverse extension of the telescopic rod 465 enable the reverse movement of the annular shell 464, thereby releasing the equipment from its fixed state. The slider 45 is moved backward, causing the pulley 44 to slide in the opposite direction on the slide groove 43 and the slider 45. The trapezoidal push block 42 is subjected to a reverse force, causing the clamping plate 41 to slide away from the fixed position. Through the reverse movement of the clamping plate 41, the clamping plate 41 is separated from the fixed position, releasing the equipment from its fixed position. The drive of the push component 46 and the movement of the slider 45 cause the pulley 44 to slide on the slide groove 43 and the slider 45, causing the trapezoidal push block 42 to drive the clamping plate 41 to slide within the connecting shell 2, thereby achieving the fixing and releasing of the equipment. Through the clamping and releasing of the clamping plate 41, and in conjunction with the coordinated movement of each part, the equipment is ensured to remain stable during operation and can be easily released from its fixed position when it needs to be moved.

[0055] The sealing mechanism 5 is located on the rear side of the housing 1. In the sealing mechanism 5, the front side of the sealing shell 51 is fixedly connected to the rear side of the housing 1, and the push plate 52 is slidably connected to the left side of the sealing shell 51. The sliding push plate 52 can change the closed state of the internal space of the sealing shell 51. By sliding the push plate 52 on the sealing shell 51 and fixing the sealing shell 51 to the rear side of the housing 1, the sealing control of the rear side of the housing 1 can be realized. The sealing mechanism 5 can seal the rear side of the housing 1 to prevent external debris from entering the interior of the housing 1 and affecting the normal operation of each mechanism.
