[0036] Figure 1 is a schematic structural view of a concrete weighing and mixing device, as shown in Figure 1 and with reference to Figures 2 to 5 The concrete weighing and mixing device provided by the embodiments of the present application comprises a mixing barrel 100, a stirring mechanism 200, a transmission mechanism, and a driving mechanism. The lower end of the mixing barrel 100 is provided with a discharge port 110. The stirring mechanism 200 comprises a rotating column 210 and a plurality of stirring blades 220. The rotating column 210 is rotatably arranged in the mixing barrel 100 and coaxially arranged in the mixing barrel 100. The plurality of stirring blades 220 are uniformly distributed along the axial direction of the rotating column 210 and circumferentially distributed along the axial direction of the rotating column 210, and the stirring blades 220 are fixedly connected to the rotating column 210.
[0037] The transmission mechanism comprises a reciprocating turntable 310, a first connecting rod 320, a second connecting rod 330, a piston cylinder 340, and a piston column 350. The reciprocating turntable 310 is coaxially and fixedly connected to the upper end of the rotating column 210. One end of the first connecting rod 320 is rotatably connected to the eccentric position of the reciprocating turntable 310. The piston cylinder 340 is in a cylindrical shape and fixedly arranged at a predetermined position. The piston column 350 is slidably arranged in the piston cylinder 340. The other end of the first connecting rod 320 is hingedly connected to the piston column 350. One end of the second connecting rod 330 is connected to the piston column 350.
[0038] The driving mechanism comprises a driving disc 410 arranged at a preset position, and a driving groove 420 is arranged on the driving disc 410. The other end of the second connecting rod 330 is slidingly inserted into the driving groove 420, so that the driving groove 420 drives the second connecting rod 330 to reciprocate along the axis direction of the piston cylinder 340 when the driving disc 410 rotates.
[0039] Specifically, the mixing barrel 100 is vertically arranged, and an opening for introducing materials into the mixing barrel 100 is arranged at the upper end. Further, the rotating column 210 drives the stirring blade 220 to rotate, so that the materials in the mixing barrel 100 can be stirred. Further, the preset position of the piston cylinder 340 is at the same horizontal position as the reciprocating turntable 310, and one end of the first connecting rod 320 is hingedly arranged at the eccentric position of the reciprocating turntable 310 to form a crank connecting rod structure, which is used to drive the rotating column 210 to rotate when the piston column 350 slides in the piston cylinder 340. Further, the piston column 350 reciprocates in the piston cylinder 340, and since the piston cylinder 340 has a short distance, the piston column 350 drives the reciprocating turntable 310 to alternately rotate forward and reverse through the first connecting rod 320.
[0040] Specifically, the driving groove 420 on the driving disc 410 can drive the piston column 350 to reciprocate in the piston cylinder 340 through the second connecting rod 330, so as to drive the stirring blade 220 to alternately rotate forward and reverse, thereby improving the stirring efficiency of the materials and fully mixing the materials to improve the material stirring quality.
[0041] In work, the required materials of concrete are introduced into the mixing barrel 100, and the driving disc 410 is rotated. The driving disc 410 drives the piston column 350 to reciprocate in the piston cylinder 340 through the second connecting rod 330, and the piston column 350 drives the rotating column 210 to alternately rotate forward and reverse through the first connecting rod 320, so that the stirring blade 220 fully stirs the materials.
[0042] In some embodiments of the present application, as shown in Figure 2 and Figure 4 The driving groove 420 comprises a plurality of first grooves 421 and a plurality of second grooves 422. The plurality of first grooves 421 and the plurality of second grooves 422 are circumferentially and uniformly arranged along the axis of the driving disc 410. The first grooves 421 and the second grooves 422 are sequentially arranged and communicated. The first grooves 421 and the second grooves 422 are arc-shaped grooves, the axis of the first grooves 421 is located on the inner side of the driving disc 410, and the axis of the second grooves 422 is located on the outer side of the driving disc 410.
[0043] Specifically, the axis of the first slot 421 and the axis of the second slot 422 are arranged on the inner and outer sides of the driving disc 410 respectively, so that the bending directions of the first slot 421 and the second slot 422 are different. The first slot 421 bends towards the axis direction of the driving disc 410, and the second slot 422 bends towards the outer side direction of the driving disc 410. Further, the driving slot 420 is provided with a sliding block connected with the other end of the second connecting rod 330, and when the sliding block slides around the axis of the driving disc 410 in the first slot 421 and the second slot 422, the sliding distance of the sliding block from the axis of the driving disc 410 alternately changes between increasing and decreasing, thereby driving the second connecting rod 330 to slide. That is, the sliding block is in a static state relative to the driving disc 410, and when the driving disc 410 rotates, the driving disc 410 drives the piston column 350 to move in the piston cylinder 340 through the driving slot 420, the sliding block and the second connecting rod 330.
[0044] In some embodiments of the present application, as shown in Figure 1 and Figure 2 The concrete weighing and mixing device further comprises a gate mechanism 500 and a weighing mechanism 600. The gate mechanism 500 is installed at the discharge port 110 and is used to control the opening and closing of the discharge port 110. The weighing mechanism 600 is arranged below the mixing barrel 100 and is electrically connected with the gate mechanism 500, and is used to open the discharge port 110 by the gate mechanism 500 when the mass of the mixing barrel 100 reaches a preset value.
[0045] Specifically, the weighing mechanism 600 is used to weigh the mixing barrel 100 as a whole, so as to obtain the weight of the material in the mixing barrel 100, and also to obtain the amount of the material introduced into the mixing barrel 100 by displaying the change value of the weight, so as to control the weight of the material introduced into the mixing barrel 100. Further, the preset value of the mass of the mixing barrel 100 is the mass of the mixing barrel 100 after discharging the concrete, and when a certain amount of concrete is needed, the gate mechanism 500 opens the discharge port 110, and after a certain amount of concrete is discharged from the discharge port 110, the weighing mechanism 600 feeds back the mass of the mixing barrel 100 to the gate mechanism 500, so that the gate mechanism 500 closes the discharge port 110. Therefore, the arrangement of the gate mechanism 500 and the weighing mechanism 600 can quantitatively discharge the concrete, so as to prevent waste caused by discharging too much concrete at a time.
[0046] In some embodiments of the present application, as shown in Figure 1 and Figure 2As shown, the concrete weighing and mixing device further comprises a control console 700, and the control console 700 is provided with a display module 720 and an operation module 710, which are used for setting the preset value of the weighing mechanism 600. Specifically, the display module 720 is used for displaying the real-time change value of the weight obtained by the weighing mechanism 600, so that the change of the amount of the material in the mixing barrel 100 can be grasped in real time, and the amount of the new material added and the concrete discharged can be obtained. Further, the operation module 710 is used for presetting the quality of the discharged concrete, and when the quality of the discharged concrete reaches the preset value, the gate mechanism 500 is closed to close the discharge port 110.
[0047] In some embodiments of the present application, as shown in Figure 3 and Figure 5 As shown, the gate mechanism 500 comprises a first opening and closing plate 510 and an opening and closing cylinder 530. The first opening and closing plate 510 is slidably inserted on the discharge port 110 to control the opening and closing of the discharge port 110. The opening and closing cylinder 530 is fixedly arranged on the discharge port 110, and the opening and closing cylinder 530 is connected with the first opening and closing plate 510. Specifically, the first opening and closing plate 510 is slidably inserted on the discharge port 110 to control the opening and closing of the discharge port 110 and the size of the opening. The opening and closing cylinder 530 is used to drive the first opening and closing plate 510 to move up and down, thereby controlling the opening and closing of the discharge port 110. Further, the opening and closing cylinder 530 and the operation module 710 are electrically connected with the weighing mechanism 600.
[0048] In some embodiments of the present application, as shown in Figure 3 and Figure 5 As shown, the gate mechanism 500 further comprises a second opening and closing plate 520 and a buffer spring 540. The discharge port 110 has a discharge bottom plate 111, and one end of the second opening and closing plate 520 is hingedly connected with the discharge bottom plate 111. The buffer spring 540 is arranged between the discharge bottom plate 111 and the second opening and closing plate 520.
[0049] Specifically, the discharge port 110 is a square tubular shape, and the discharge bottom plate 111 is the bottom of the discharge port 110. Further, since the buffer spring 540 is arranged between the discharge bottom plate 111 and the second opening and closing plate 520, in the initial state, the buffer spring 540 makes the second opening and closing plate 520 and the discharge bottom plate 111 have a preset angle, and when the second opening and closing plate 520 is subjected to pressure, the preset angle is reduced, and the buffer spring 540 is compressed. Therefore, when the concrete is discharged from the discharge port 110, the concrete passes through the second opening and closing plate 520, and since the second opening and closing plate 520 and the discharge bottom plate 111 have a preset angle, the discharge speed of the concrete passing through the second opening and closing plate 520 is slowed down, thereby preventing the kinetic energy of the concrete from being too large to cause damage to the discharge port 110 or the receiving carrier.
[0050] In some embodiments of the present application, as shown inFigure 3 As shown, the plurality of stirring blades 220 are respectively a plurality of first blades and a plurality of second blades. The spiral directions of the first blades and the second blades are opposite. Specifically, the first blades and the second blades are oppositely arranged in the spiral directions, so that the directions of the first blades and the second blades for stirring the materials are different during the rotation of the rotating column 210, thereby further improving the stirring efficiency of the materials.
[0051] In some embodiments of the present application, as shown in Figure 1 As shown, the concrete weighing and stirring device further comprises a support frame 800, and the mixing barrel 100, the transmission mechanism and the driving mechanism are all arranged on the support frame 800. The driving mechanism further comprises a driving motor 430, and the driving motor 430 is connected with the driving disc 410. Specifically, the piston cylinder 340 and the driving disc 410 are arranged at the preset positions through the support frame 800.
