Detailed Embodiments

[0028] The following will describe in detail the embodiments of the present invention. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0029] First Embodiment:

[0030] Please refer to Figures 1 to 4 , the present invention provides a high-humidity rare earth compound automatic metering and loading system, including a storage bin 101, a canvas 102, a support base 103, an anti-arching mechanism, a flattening mechanism, a support frame 104, a base 105, a conveying roller 106, a conveying wheel 107, a loading box 108, a support plate 109, a baffle 110 and a driving mechanism. The anti-arching mechanism includes a support block 111, a hydraulic telescopic rod 112 and a pushing plate 113. The flattening mechanism includes a fixing plate 114, an electric telescopic rod 115 and a discharging plate 116. The driving mechanism includes a driving motor 117, a first gear 118 and a second gear 119.

[0031] In this embodiment, the conveying roller 106 rotates along its own axis between the two support frames 104, thereby driving the conveying wheel 107 to rotate along its own axis between the two support frames 104, and further driving the loading box 108 to be conveyed from left to right on the conveying wheel 107. When the loading box 108 is conveyed directly below the silo 101, the support plate 109 is lifted to support the loading box 108, and then the material in the silo 101 is discharged and dropped into the loading box 108. At this time, the weight detection sensor 120 below the support plate 109 can detect the material in the loading box 108 in real time, so that when the weight of the material in the loading box 108 reaches the specified weight, the flattening mechanism can be used to flatten the material. After flattening, the loading box 108 is continuously conveyed to facilitate subsequent processing of the material in the loading box 108, thereby achieving precise automatic metering and feeding.

[0032] Among them, part of the canvas 102 is placed on the silo 101 and part extends into the silo 101. The support base 103 has an opening. The silo 101 is arranged in the opening of the support base 103 and extends below the support base 103. The arch breaking mechanism is located on the support base 103, and the flattening mechanism is located below the support base 103. The number of the support frames 104 is two, and they are respectively arranged on the front and rear sides below the support base 103. The base 105 is arranged below the support frames 104. The number of the conveying rollers 106 is several, and they are evenly and rotatably arranged between the two support frames 104. The conveying wheels 107 are arranged on the front and rear sides outside each conveying roller 106. The loading box 108 is arranged on the conveying wheels 107. The support plate 109 is slidably arranged on the base 105 and is located between two adjacent conveying rollers 106. The weight detection sensor 120 is arranged below the support plate 109. The canvas 102 can be shaken in the silo 101, so that the material adhered to the canvas 102 can gradually fall off. The weight detection sensor 120 below the support plate 109 can detect the weight on the support plate 109 in real time, and after detection, transmit the detection result to an external intelligent terminal, so that the external intelligent terminal can judge the detection result, and after judgment, generate a corresponding control instruction, and control the start and stop of each electrical component according to this control instruction.

[0033] Secondly, the baffle 110 is slidably arranged outside the conveying roller 106 and is located between the two conveying wheels 107 outside the conveying roller 106. When the baffle 110 is in contact with the conveying roller 106, the height of the highest point of the baffle 110 is lower than the height of the highest point of the conveying wheel 107. The baffle 110 is U-shaped and can block the conveying position of the loading box 108.

[0034] Thirdly, the up and down movement of the baffle 110 outside the conveying roller 106 and the up and down movement of the support plate 109 on the base 105 are both driven by the pneumatic telescopic rod 121.

[0035] Meanwhile, the support block 111 is arranged on the support seat 103, the hydraulic telescopic rod 112 is arranged on the support block 111, the output end of the hydraulic telescopic rod 112 penetrates through the silo 101 and is connected to the pushing plate 113. The pushing plate 113 is located between the silo 101 and the canvas 102. The output end of the hydraulic telescopic rod 112 is connected to the pushing plate 113 and drives the pushing plate 113 to move between the silo 101 and the canvas 102, so that the pushing plate 113 can shake the canvas 102, thereby enabling the canvas 102 to be shaken in the silo 101, and further enabling the materials adhered to the canvas 102 to gradually fall off, realizing the arch breaking of the materials adhered to the canvas 102.

[0036] In addition, the fixing plate 114 is arranged under the support seat 103, the electric telescopic rod 115 is arranged on the side of the fixing plate 114 close to the loading box 108, the discharging plate 116 is connected to the output end of the electric telescopic rod 115 and is located under the silo 101. The output end of the electric telescopic rod 115 is connected to the discharging plate 116 and drives the discharging plate 116 to move horizontally under the silo 101, so that the discharging plate 116 can open or close the discharging port under the silo 101. A convex plate 122 is arranged under the discharging plate 116, and the convex plate 122 can flatten the materials in the loading box 108.

[0037] Finally, the driving motor 117 is arranged on one side of the support frame 104 away from the conveying wheel 107. The first gears 118 are evenly arranged outside the output shaft of the driving motor 117. Each first gear 118 is meshed with a second gear 119 outside it, and each second gear 119 is arranged at one end of the corresponding conveying roller 106 away from the loading box 108. The first gears 118 and the second gears 119 are both bevel gears, and the first gears 118 and the second gears 119 are vertically arranged. After the driving motor 117 is started, the output shaft of the driving motor 117 will rotate along its own axis, so as to drive the first gear 118 to rotate along the axis of the output shaft of the driving motor 117, and further drive the second gear 119 to rotate along its own axis. Through the rotation of the second gear 119 along its own axis, the conveying roller 106 can be driven to rotate along its own axis between the two support frames 104.

[0038] When using a high-humidity rare earth compound automatic metering and loading system of this embodiment, the pneumatic telescopic rod 121 is used to drive the baffle 110 to move up and down above the base 105, and the baffle 110 is moved upward. When the height of the baffle 110 exceeds the height of the conveying wheel 107, the loading box 108 is placed on the conveying wheel 107, and the driving motor 117 is started, so that the power output by the output shaft of the driving motor 117 drives the first gear 118 to rotate along the axis of the output shaft of the driving motor 117, so as to drive the second gear 119 to rotate along its own axis, and further drive the conveying roller 106 to rotate along its own axis between the two support frames 104. Through the rotation of the conveying roller 106 along its own axis between the two support frames 104, the conveying wheel 107 can be driven to rotate along its own axis between the two support frames 104, and further drive the loading box 108 to be conveyed from left to right on the conveying wheel 107.

[0039] When the loading box 108 contacts the baffle 110 during the process of being conveyed from left to right, the baffle 110 will block the loading box 108. At this time, the loading box 108 will no longer continue to be conveyed from left to right, and the loading box 108 is located directly below the silo 101.

[0040] After the charging bin 108 stops conveying, the pneumatic telescopic rod 121 drives the support plate 109 to move up and down above the base 105. The support plate 109 moves upward until it contacts the charging bin 108. After contact, the support plate 109 continues to move upward so that the support plate 109 can support the charging bin 108. At this time, the weight detection sensor 120 below the support plate 109 can detect the total weight of the support plate 109 and the charging bin 108 in real time.

[0041] Start the electric telescopic rod 115 so that the power output from the output end of the electric telescopic rod 115 drives the discharge plate 116 to move horizontally below the support seat 103. The discharge plate 116 moves towards the fixed plate 114 to open the discharge port of the silo 101, and the materials in the silo 101 fall into the charging bin 108. At this time, the weight detection sensor 120 below the support plate 109 can detect the total weight of the support plate 109 and the charging bin 108 in real time, so that the weight of the fallen materials can be determined according to the weight difference of the charging bin 108. After materials adhere to the canvas 102, start the hydraulic telescopic rod 112 so that the power output from the output end of the hydraulic telescopic rod 112 drives the push plate 113 to move between the silo 101 and the canvas 102, so that the push plate 113 can shake the canvas 102, so that the canvas 102 can be shaken in the silo 101, and then the materials adhering to the canvas 102 can gradually fall off, realizing the arch breaking of the materials adhering to the canvas 102.

[0042] When the weight of the materials in the charging bin 108 reaches the specified weight, the discharge plate 116 moves horizontally in the opposite direction, so that the discharge plate 116 can close the discharge port of the silo 101, and then the automatic metering and loading of the materials in the charging bin 108 can be completed.

[0043] After the loading is completed, the support plate 109 continues to move upward, driving the materials in the charging bin 108 to move upward until the materials in the charging bin 108 contact the convex plate 122 of the support plate 109. Then, the support plate 109 moves up and down repeatedly, so that the convex plate 122 can flatten the materials in the charging bin 108.

[0044] After the material in the charging box 108 is flattened, first lower the support plate 109. When the height of the highest point of the support plate 109 is lower than the height of the highest point of the conveying wheel 107, the charging box 108 is placed on the conveying wheel 107. Then lower the baffle 110. When the baffle 110 moves down and contacts the conveying roller 106, the baffle 110 no longer blocks the charging box 108, so that the charging box 108 can continue to be conveyed from left to right on the conveying wheel 107, facilitating subsequent processing of the material in the charging box 108, and thus completing the entire automatic metering and charging process.

[0045] Second Embodiment:

[0046] Based on the first embodiment, please refer to Figure 5 , the present invention further provides an automatic metering and charging method for high-humidity rare earth compounds, including the following steps:

[0047] S101. First, raise the baffle 110 so that the height of the baffle 110 exceeds the height of the conveying wheel 107. Then place the charging box 108 on the conveying wheel 107 and let the charging box 108 be conveyed from left to right on the conveying wheel 107.

[0048] Specifically, the pneumatic telescopic rod 121 is used to drive the baffle 110 to move up and down above the base 105, causing the baffle 110 to move up. When the height of the baffle 110 exceeds the height of the conveying wheel 107, place the charging box 108 on the conveying wheel 107, and start the driving motor 117, so that the power output by the output shaft of the driving motor 117 drives the first gear 118 to rotate along the axis of the output shaft of the driving motor 117, thereby driving the second gear 119 to rotate along its own axis, and further driving the conveying roller 106 to rotate along its own axis between the two support frames 104. Through the rotation of the conveying roller 106 along its own axis between the two support frames 104, the conveying wheel 107 can be driven to rotate along its own axis between the two support frames 104, and further drive the charging box 108 to be conveyed from left to right on the conveying wheel 107.

[0049] S102. When the charging box 108 contacts the baffle 110, the baffle 110 blocks the charging box 108. At this time, the charging box 108 no longer continues to be conveyed from left to right and is located directly below the silo 101.

[0050] Specifically, when the loading box 108 contacts the baffle 110 during the left-to-right conveying process, the position sensor at the baffle 110 will stop the driving motor 117 when detecting the arrival of the loading box 108 at this position, so that the loading box 108 will no longer continue to be conveyed from left to right. At the same time, the baffle 110 is lifted again until the height of the highest point of the baffle 110 is higher than the height of the highest point of the loading box 108, so that the baffle 110 will block the loading box 108. At this time, under the blocking action of the baffle 110, the loading box 108 will no longer move, and the loading box 108 is located directly below the silo 101.

[0051] S103. First, lift the support plate 109 to gradually bring the support plate 109 into contact with the loading box 108. After contact, continue to lift the support plate 109 so that the weight detection sensor 120 below the support plate 109 can detect the weight of the loading box 108 in real time.

[0052] Specifically, after the loading box 108 no longer continues to be conveyed from left to right, start the pneumatic telescopic rod 121, so that the power output from the output end of the pneumatic telescopic rod 121 drives the support plate 109 to move up and down above the base 105, lift the support plate 109 so that the support plate 109 can contact the loading box 108, and after contact, continue to lift the support plate 109 so that the support plate 109 can support the loading box 108. When the support plate 109 drives the loading box 108 to move to the middle position between the discharge plate 116 and the conveying roller 106, start the weight detection sensor 120, so that the weight detection sensor 120 below the support plate 109 will detect the total weight of the support plate 109 and the loading box 108 in real time.

[0053] S104. Then, horizontally move the discharge plate 116 to open the discharge port of the silo 101, and drop the materials in the silo 101 into the loading box 108. At this time, determine the weight of the materials according to the weight difference of the loading box 108.

[0054] Specifically, start the electric telescopic rod 115, so that the power output from the output end of the electric telescopic rod 115 drives the feeding plate 116 to move horizontally below the support seat 103, and make the feeding plate 116 move towards the fixed plate 114, opening the discharge port of the bin 101, and dropping the materials in the bin 101 into the loading box 108. At this time, the weight detection sensor 120 below the support plate 109 can detect the total weight of the support plate 109 and the loading box 108 in real time, so as to determine the weight of the dropped materials according to the weight difference of the loading box 108. After the canvas 102 adheres to materials, start the hydraulic telescopic rod 112, so that the power output from the output end of the hydraulic telescopic rod 112 drives the pushing plate 113 to move between the bin 101 and the canvas 102, so that the pushing plate 113 can shake the canvas 102, so that the canvas 102 can be shaken in the bin 101, and then the materials adhered to the canvas 102 can gradually fall off, realizing the arch breaking of the materials adhered to the canvas 102.

[0055] S105. When the weight of the materials in the loading box 108 reaches the specified weight, move the feeding plate 116 horizontally in the opposite direction to close the discharge port and complete the automatic weighing of the materials.

[0056] Specifically, when the weight of the materials in the loading box 108 reaches the specified weight, move the feeding plate 116 horizontally in the opposite direction, so that the feeding plate 116 can close the discharge port of the bin 101, and then the automatic weighing and loading of the materials in the loading box 108 can be completed.

[0057] S106. Continue to move the support plate 109 upward to drive the materials in the loading box 108 upward until the materials contact the convex plate 122 of the support plate 109, and then move the support plate 109 up and down repeatedly to flatten the materials.

[0058] Specifically, after the loading is completed, continue to move the support plate 109 upward to drive the materials in the loading box 108 upward. When the materials in the loading box 108 contact the convex plate 122 of the support plate 109 during the upward movement, move the support plate 109 up and down repeatedly and slightly, so that the convex plate 122 can flatten the materials in the loading box 108.

[0059] S107. After flattening the materials, first move the support plate 109 downward, and then move the baffle 110 downward to let the loading box 108 be conveyed from left to right on the conveying wheels 107 to complete the entire automatic weighing and loading process.

[0060] Specifically, after the material in the charging bin 108 is flattened, first lower the support plate 109. When the height of the highest point of the support plate 109 is lower than the height of the highest point of the conveying wheel 107, place the charging bin 108 on the conveying wheel 107, and then lower the baffle 110. When the baffle 110 moves down to contact the conveying roller 106, the baffle 110 no longer blocks the charging bin 108, so that the charging bin 108 can continue to be conveyed from left to right on the conveying wheel 107, facilitating subsequent processing of the material in the charging bin 108, and thus completing the entire automatic metering and charging process.

7. A method for automatically metering and charging high-humidity rare earth compounds, applied to the automatic metering and charging system for high-humidity rare earth compounds according to any one of claims 1 to 6, characterized in that: The following steps are involved: First, move the baffle upwards so that the height of the baffle exceeds the height of the conveying wheel, and then place the loading box on the conveying wheel, so that the loading box is conveyed from left to right on the conveying wheel; When the loading box contacts the baffle, the baffle blocks the loading box. At this time, the loading box no longer continues to be transported from left to right and is located directly below the silo; First, the support plate is moved upward to allow the support plate to gradually contact the charging box, and after contact, the support plate is continued to be moved upward to allow the weight detection sensor under the support plate to detect the weight of the charging box in real time; Then, the discharge plate is moved horizontally to open the discharge port of the silo, and the material in the silo is dropped into the charging box. At this time, the weight of the material is determined according to the weight difference of the charging box; When the weight of the material in the loading box reaches a specified weight, the discharge plate is moved laterally in the opposite direction so that the discharge port is closed, thereby completing the automatic measurement of the material; Continue to move the support plate upward to drive the material in the loading box upward until the material contacts the convex plate of the support plate, and then repeatedly move the support plate up and down to flatten the material; After the material is flattened, the support plate is first moved downward, and then the baffle is moved downward, so that the charging box is conveyed from left to right on the conveying wheel, completing the entire automatic metering and charging process.
