Description

Technical Field

[0001] This utility model relates to the field of belt scale technology, and in particular to a quantitative loading and metering belt scale. Background Technology

[0002] A belt scale is a dynamic weighing device installed on a belt conveyor. It can continuously weigh bulk materials on the belt without interrupting the material conveying process. Quantitative loading and metering belt scales are used to achieve accurate metering and automated control during the loading of bulk materials. Its core function is to combine high-precision sensors with an intelligent control system to measure the weight of materials in real time and dynamically adjust loading parameters to ensure that the weight of each truckload of materials meets the preset standard.

[0003] Chinese patent document CN213902583U discloses a quantitative loading and metering belt scale, including a belt scale, a support frame fixedly mounted on the belt scale, a feeding mechanism fixedly mounted on the support frame, and a lifting mechanism fixedly mounted below the belt scale. The feeding mechanism includes a material bucket, a discharge pipe fixedly inserted inside the material bucket, and a through hole in the discharge pipe. A first motor is fixedly mounted on the support frame, and a connecting rod is provided at the output end of the first motor. A threaded block is fixedly mounted on the connecting rod, and the threaded block is tangent to the inner side of the discharge pipe. The lifting mechanism includes a second fixing block and a second motor. This invention features a feeding mechanism, and the timing of the first motor's rotation can be controlled by a relay to achieve quantitative feeding and loading. The lifting mechanism allows adjustment of the belt scale's height, accommodating vehicles of different heights and facilitating loading.

[0004] The existing technology has the following problems:

[0005] Although the above-mentioned utility model can adjust the height of the belt scale through the lifting mechanism, the motor drives the rotating shaft and gears to rotate so that the belt scale can be raised or lowered. The lack of self-locking between the gears causes the belt scale to sink when it is too heavy. In addition, the continuous output of materials during the conveying process cannot divide the materials evenly for loading, resulting in different loading qualities in different vehicles.

A support plate is fixedly connected to the left side of the middle of opposite sides of the two support plates. A motor is fixedly connected to the upper surface of the support plate. A turntable is fixedly connected to the output end of the motor. A connecting rod is rotatably connected to the lower right side of the turntable.

[0011] Preferably, the upper surface of the support plate two is fixedly connected to two limiting plates one distributed front and back, and the middle part of the outer periphery of the turntable is rotatably connected to the opposite side of the two limiting plates one.

Connecting plates are rotatably connected to the front and rear sides of the two vertically distributed connecting blocks.

[0014] Preferably, limit blocks 1 are fixedly connected to both the front and rear sides of the slider, and two sets of limit blocks 1 distributed in the front and rear are slidably connected to the middle of the front and rear sides of the slide rail 2, and limit blocks 2 are fixedly connected to the middle of the slide rail 2.

Through the cooperation of a feeding box, a discharge pipe, a first motor, a spiral fan blade, a second support plate, a second motor, a turntable, a connecting rod, a first slide rail, an opening and closing plate, and a first limit plate, the first motor drives the spiral fan blade to uniformly transport materials to the top of the conveyor belt. The second motor drives the turntable, causing the connecting rod to drive the opening and closing plate to perform reciprocating linear motion. The reciprocating interval of the opening and closing plate is adjusted according to the flow rate output by the spiral fan blade, so that the material divided by the opening and closing plate each time reaches the required value for loading. This achieves uniform transportation and division of materials, ensures that the quality of the loaded materials is the same, improves the accuracy and stability of quantitative loading, and meets the strict requirements for material metering in industrial production.

Through the cooperation of a support pipe, support column, limit plate two, support seat, motor three, slide rail two, threaded rod, slider, limit block one, connecting block, connecting plate and limit block two, the motor three drives the threaded rod to rotate, causing the slider to move linearly along the axis. The connecting plate converts the linear motion of the slider into the vertical lifting motion of the base plate. At the same time, the support column and support pipe limit the lifting trajectory, realizing the lifting of the weighing scale to meet the loading height of different vehicles. Meanwhile, the self-locking property of the threaded rod can prevent the equipment from sliding down due to gravity when it stops. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figures 1-7 As shown, a quantitative loading and metering belt scale includes a base plate 1, two baffles 2 distributed front and rear are fixedly connected to the upper surface of the base plate 1, a conveyor belt 3 is movably connected to the opposite side of the two baffles 2, a support plate 4 is fixedly connected to the upper surface of the baffles 2, and a conveying mechanism 5 is fixedly connected to the left side of the opposite side of the two support plates 4.

[0029] The conveying mechanism 5 includes a feeding box 51, which is fixedly connected to the left side of the two support plates 4 on opposite sides. A discharge pipe 52 is fixedly connected to the lower right side of the feeding box 51. A spiral fan blade 54 is rotatably connected to the middle of the inner cavity of the feeding box 51. A motor 53 is fixedly connected to the left side of the feeding box 51. The left end of the spiral fan blade 54 is fixedly connected to the output end of the motor 53. The right side of the outer periphery of the spiral fan blade 54 is rotatably connected to the inside of the discharge pipe 52. The front and rear sides of the bottom of the inner cavity of the feeding box 51 are inclined towards the spiral fan blade 54.

[0030] It should be noted that the base plate 1 provides a stable installation platform for all other components, ensuring that each component can be accurately installed and operated according to design requirements. The baffle 2 primarily functions to limit and protect the conveyor belt 3, preventing it from shifting during operation and blocking material from spilling from both sides of the conveyor belt 3 during transport, thus reducing material waste. The conveyor belt 3, through its own cyclical motion, receives material from the conveying mechanism 5 and transports it to the opening and closing mechanism 6 at a set speed and direction, achieving continuous and stable material transport within the equipment. This is a crucial link in enabling the quantitative loading and metering belt scale to perform its quantitative loading function.

[0031] The feeding bin 51 is the main container of the conveying mechanism 5, used to hold the materials to be conveyed. The feeding bin 51 provides a temporary storage space for the materials, ensuring they can enter the subsequent conveying stages in an orderly manner. The discharge pipe 52 is the channel through which materials are conveyed from the feeding bin 51 to the conveyor belt 3. The design of the discharge pipe 52 controls the outflow direction and flow rate of the materials, ensuring they fall accurately onto the conveyor belt 3, preparing for subsequent quantitative conveying. The motor 53 outputs power to drive the spiral fan blade 54 to rotate, thereby realizing the conveying of materials. The speed and operating status of the motor 53 can be adjusted according to actual needs to control the conveying speed and flow rate of the materials. The structure of the spiral fan blade 54 effectively achieves uniform material conveying, preventing blockages or accumulation of materials within the feeding bin 51. The front and rear sides of the bottom of the inner cavity of the feeding bin 51 are inclined towards the spiral fan blade 54, which facilitates the automatic concentration of materials towards the spiral fan blade 54, improving material conveying efficiency.

[0032] like Figure 6 As shown, an opening and closing mechanism 6 is fixedly connected to the middle of the upper surface of the two support plates 4. The opening and closing mechanism 6 includes two slide rails 65. The opposite sides of the two slide rails 65 are fixedly connected to the middle of the opposite side of the two support plates 4. An opening and closing plate 66 is slidably connected to the opposite side of the two slide rails 65. A support plate 61 is fixedly connected to the left side of the middle of the opposite side of the two support plates 4. A motor 62 is fixedly connected to the upper surface of the support plate 61. A turntable 63 is fixedly connected to the output end of the motor 62. A connecting rod 64 is rotatably connected to the lower right side of the turntable 63. The upper part of the connecting rod 64 is rotatably connected to the upper surface of the opening and closing plate 66.

[0033] It should be noted that support plate 2 61 provides a mounting platform for motor 2 62, ensuring that motor 2 62 can be stably fixed on the equipment and providing support for the normal operation of opening and closing mechanism 6. Motor 2 62 drives turntable 63 to rotate by outputting power, which in turn drives opening and closing plate 66 to move through connecting rod 64, realizing the opening and closing control of the material conveying channel. Turntable 63, as a transmission component, converts the rotational motion of motor 2 62 into the reciprocating motion of connecting rod 64. Connecting rod 64 plays the role of transmitting power, converting the rotational motion of turntable 63 into the linear motion of opening and closing plate 66, enabling opening and closing plate 66 to open and close in a set manner, controlling the material conveying volume and timing. Slide rail 1 65 provides guidance for the movement of opening and closing plate 66, ensuring that opening and closing plate 66 can move smoothly and accurately along the predetermined direction, realizing the opening and closing function of the material conveying channel.

[0034] like Figure 6 As shown, two limiting plates 67 are fixedly connected to the upper surface of the support plate 61, and the middle of the outer periphery of the turntable 63 is rotatably connected to the opposite side of the two limiting plates 67.

[0035] It should be noted that the function of the limiting plate 67 is to limit and support the turntable 63, ensuring that the turntable 63 remains stable during rotation, preventing the turntable 63 from shifting or shaking, and ensuring the normal operation of the opening and closing mechanism 6.

[0036] like Figure 2 and Figure 3 As shown, four support mechanisms 7 arranged in a rectangular pattern are fixedly connected to the lower surface of the base plate 1. Each support mechanism 7 includes a support column 72, a support tube 71 is slidably connected to the outer periphery of the support column 72, a limit plate 73 is fixedly connected to the lower surface of the support column 72, and the outer periphery of the limit plate 73 is slidably connected to the inner cavity of the support tube 71. A lifting mechanism 8 is fixedly connected to the lower surface of the base plate 1.

[0037] It should be noted that the support tube 71 provides sliding space for the support column 72, allowing the support column 72 to slide up and down within the support tube 71, thereby adjusting the equipment height. The support column 72 is the main supporting component of the support mechanism 7; it adjusts the equipment height through sliding cooperation with the support tube 71. The limiting plate 73 restricts the sliding range of the support column 72, preventing it from sliding out of the support tube 71.

[0038] like Figure 4 and Figure 5 As shown, the lifting mechanism 8 includes a support base 81, which is fixedly connected to the opposite side of four support tubes 71. A slide rail 83 is fixedly connected to the middle of the upper surface of the support base 81. A motor 82 is fixedly connected to the right side of the slide rail 83. A threaded rod 84 is rotatably connected to the middle of the slide rail 83. A slider 85 is threadedly connected to the outer circumference of the threaded rod 84. Connecting blocks 87 are fixedly connected to the upper surface of the slider 85 and the left and right sides of the lower surface of the base plate 1. Connecting plates 88 are rotatably connected to the front and rear sides of the two vertically distributed connecting blocks 87.

[0039] It should be noted that the support base 81 provides the mounting foundation for other components of the lifting mechanism 8, connecting the four support tubes 71 into a whole, thus enhancing the overall stability of the equipment. Motor 3 82 drives the threaded rod 84 to rotate by outputting power, thereby moving the slider 85. Slide rail 2 83 provides a track for the slider 85, ensuring that it can slide smoothly along a straight line. When motor 3 82 drives the threaded rod 84 to rotate, the threaded rod 84, through its threaded engagement with the slider 85, converts the rotational motion into the linear motion of the slider 85. Driven by the threaded rod 84, the slider 85 slides along slide rail 2 83, driving the connecting plate 88 to move via the connecting block 87, thereby achieving height adjustment of the base plate 1 and other components on the equipment. The connecting block 87 connects the slider 85 and the connecting plate 88, converting the linear motion of the slider 85 into angular changes in the connecting plate 88, thus achieving height adjustment of the equipment. The movement of the connecting plate 88 can convert the linear motion of the slider 85 into vertical lifting motion of the base plate 1, meeting the needs of different loading heights.

[0040] like Figure 5 As shown, limit blocks 86 are fixedly connected to both the front and rear sides of slider 85. Two sets of limit blocks 86 are slidably connected to the middle of the front and rear sides of slide rail 83. Limit block 89 is fixedly connected to the middle of slide rail 83.

[0041] It should be noted that the function of limit block 86 is to limit and guide the sliding of slider 85, ensuring that slider 85 remains stable during sliding and preventing slider 85 from deviating or shaking, thus ensuring the normal operation of lifting mechanism 8. Limit block 89 limits the sliding range of slider 85, preventing slider 85 from exceeding the effective sliding area of ​​slide rail 83, thus ensuring the safety and reliability of lifting mechanism 8.

[0042] like Figure 1 As shown, a ramp 9 is fixedly connected to the upper surface of the right side of the base plate 1.

[0043] It should be noted that ramp 9 guides the materials transported by conveyor belt 3 into the interior of the carriage.

[0044] The working principle of this utility model is as follows: The operator pours the material to be conveyed into the feeding box 51. Under its own gravity, the material will automatically concentrate towards the spiral fan blade 54. The motor 53 is started, and the motor 53 outputs power to drive the spiral fan blade 54 to rotate in the feeding box 51. The material is conveyed along the spiral trajectory of the spiral fan blade 54 to the discharge pipe 52, and then accurately falls onto the conveyor belt 3 through the discharge pipe 52. When it is necessary to control the quantity of material, the motor 62 is started to drive the turntable 63 to rotate. As the turntable 63 rotates, the connecting rod 64 will pull or push the opening and closing plate 66 to slide along the slide rail 65. When the opening and closing plate 66 slides to the closed position, the material conveying channel is blocked. At this time, the amount of material on the right side of the opening and closing mechanism 6 on the conveyor belt 3 is the set quantity.

[0045] When the height of the equipment needs to be adjusted, the starting motor 82 drives the threaded rod 84 to rotate in the middle of the slide rail 83. The slider 85 slides along the slide rail 83 under the drive of the threaded rod 84, and through the connecting block 87, it drives the connecting plate 88 to move. The connecting plate 88 converts the linear motion of the slider 85 into the vertical lifting motion of the base plate 1. The lifting of the base plate 1 causes the height of the entire equipment to change, thus meeting the needs of different loading heights. After quantitative control and height adjustment, the material continues to be conveyed forward by the conveyor belt 3, eventually reaching the ramp 9. The ramp 9 guides the material transported by the conveyor belt 3 into the carriage, realizing the loading of the material.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
