[0020] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] In the description of this application, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0023] The following is combined with Figures 1 to 4 The embodiments of this utility model are described below.

[0024] This application provides an aggregate metering device, which includes a frame 600;

[0025] Multiple aggregate storage boxes 10 are fixedly mounted on the frame 600, and each aggregate storage box 10 is equipped with a weight sensor 500.

[0026] A calibration component is mounted on the frame 600. The calibration component includes a horizontally movable slider 800, a lifting mechanism connected to the horizontal slider 800, and a counterweight detection weight 120 carried by the lifting mechanism. The horizontal slider 800 can move the counterweight detection weight 120 to the corresponding aggregate storage frame 10, and the lifting mechanism lowers the counterweight detection weight 120 to calibrate the weight sensor 500.

[0027] During calibration, the horizontal sliding slider 800 moves laterally, transporting the counterweight 120 above the target aggregate storage frame 10. The lifting mechanism lowers the weight, causing it to fall into the aggregate storage frame 10. Its weight is detected by the weight sensor 500, and calibration is completed by manual verification of the weight sensor 500. This improves calibration efficiency and reduces operational difficulty. After calibration, the lifting mechanism raises the weight back to its original position. After calibration, the aggregate storage frame 10 can be used to hold aggregates, and the weight of the aggregates can be directly detected by the calibrated weight sensor 500.

[0028] Therefore, the counterweights are moved via the horizontal sliding block 800 to accommodate the calibration needs of multiple storage bins, eliminating the need to externally transport or retrieve the weights. When calibrating the weight sensors 500 in different storage bins, it is also unnecessary to manually move the weights to the corresponding bins one by one, thus improving calibration efficiency and reducing operational complexity. Furthermore, the calibration components are mounted on the frame 600, featuring a compact structure that eliminates the need for disassembly when calibration is not required; they can be moved to a position that does not occupy unloading space via the horizontal sliding block 800.

[0029] In some embodiments, the calibration assembly further includes a transverse slide rail 700, which is fixedly mounted on the frame 600. A transverse slider 800 is mounted on the transverse slide rail 700. The transverse slider 800 and the transverse slide rail 700 cooperate to restrict the slider's movement, ensuring accurate weight movement and preventing deviation. The transverse slider 800 slides along the transverse slide rail 700 fixed on the frame 600, smoothly moving the counterweight detection weight 120 above the corresponding aggregate storage frame 10. This improves the stability of the transverse slider 800's movement, ensuring the weight accurately acts on the calibration position of the storage frame and reducing equipment damage caused by the weight impacting the storage frame.

[0030] In some embodiments, the lifting mechanism includes a bracket 900, a wound outer wheel 100, a rotating shaft 110, and an extension line 170. The bracket 900 is fixed to the transverse slider 800, the rotating shaft 110 is mounted on the bracket 900, the wound outer wheel 100 is sleeved on the rotating shaft 110, one end of the extension line 170 is wound around the rotating shaft 110, and the other end is connected to the counterweight detection weight 120. Rotation of the rotating shaft 110 drives the wound outer wheel 100 to rotate, thus winding and unwinding the extension line 170 wound on the shaft, thereby controlling the lifting and lowering of the counterweight detection weight 120, achieving contact or separation between the counterweight weight and the aggregate storage frame 10. Thus, the lifting and lowering of the weight is driven by the winding and unwinding of the extension line 170, controlling the descent height and contact force of the weight. During actual assembly, the motor is fixed on the transverse slider 800, and the rotating shaft 110 can cooperate with the output shaft of the motor to drive the rotating shaft 110 to rotate so as to realize the lifting and lowering of the configuration detection weight.

[0031] Optionally, multiple rotating shafts 110 can be used, and multiple detection weights can be configured accordingly. The weights of the multiple counterweight detection weights 120 can be different and arranged in ascending order. Alternatively, multiple aggregate storage frames 10 can be arranged equidistantly laterally, and the multiple counterweight detection weights 120 and aggregate storage frames 10 can be quickly moved to each aggregate storage frame 10. This reasonable layout saves space and improves stability and operating efficiency. Alternatively, a control panel 130 can be provided to configure the lifting mechanism and the lateral slider for convenient control of their movement.

[0032] In some embodiments, a stabilizing mechanism is further included, comprising an auxiliary rod 140, a contact plate 150, and a spring 160. The auxiliary rod 140 is fixed to the transverse slider 800. One end of the spring 160 is fixed to the auxiliary rod 140, and the other end is fixed to the contact plate 150. The contact plate 150 contacts the side of the winding outer wheel 100 to provide lateral stabilization when the counterweight detection weight 120 descends. When the counterweight detection weight 120 descends, the winding outer wheel 100 rotates, and the contact plate 150, under the elastic force of the spring 160, abuts against the side of the winding outer wheel 100, reducing large lateral swaying of the outer wheel and stabilizing the lifting trajectory of the weight.

[0033] In some embodiments, the auxiliary rod 140 is an L-shaped rod, which includes a vertical portion and a horizontal portion connected to each other. The vertical portion is fixedly connected to the horizontal sliding block 800, and the spring 160 is disposed on the horizontal portion. The vertical portion of the L-shaped auxiliary rod 140 is fixed to the horizontal sliding block 800, and the horizontal portion provides a mounting carrier for the spring 160. The contact plate 150 is connected to the horizontal portion through the spring 160, maintaining stable contact with the side of the winding outer wheel 100 and improving the installation firmness of the stabilizing mechanism.

[0034] In some embodiments, the aggregate metering device further includes a discharge control mechanism disposed at the lower end of the aggregate storage frame 10, which is used to control the discharge of aggregate. After the aggregate metering is completed, the discharge channel at the lower end of the aggregate storage frame 10 is opened by controlling the opening and closing state of the discharge channel to discharge the metered aggregate as needed; the channel is kept closed during the metering process to avoid aggregate leakage affecting the metering accuracy.

[0035] Optionally, the feeding control mechanism includes a feeding port pipe 200, a driving component 400, and a baffle plate 300. The feeding port pipe 200 is connected to the lower end of the aggregate storage frame 10, and the baffle plate 300 is movably disposed at the lower end of the feeding port pipe 200. The driving component is connected to the baffle plate to drive its opening and closing. The driving component drives the baffle plate to move, opening or closing the outlet of the feeding port pipe: during metering, the baffle plate closes, sealing the feeding channel; during discharge, the baffle plate opens, and the aggregate is discharged along the feeding port pipe. By cooperating with the feeding port pipe, the channel opening and closing is realized, precisely controlling the timing and amount of aggregate discharge.

Since this asphalt mixing plant uses the aggregate metering device disclosed in the embodiments of this application, it also possesses the technical advantages of the aggregate metering device disclosed in the embodiments of this application, which will not be described in detail in the embodiments of this application.
