[0083] See also Figure 1 and Figure 2 The present invention provides a conductive concrete medium conductivity testing device for pile foundations, comprising: a device body 5, a mixing and feeding mechanism 1, a conveying mechanism 2, a pressing mechanism 3, and a detection mechanism 4; the device body 5 is provided with: a filling station, a pressing station, and a detection station;

[0084] See also Figures 3 to 5 The mixing and unloading mechanism 1 includes: a support frame 106, a mixing box 112 and a material trough 105; the support frame 106 is arranged on the filling station, and a unloading assembly is arranged on the support frame 106. The unloading assembly is used to supply the mixing box 112 and tilt the mixing box 112. In this embodiment, the unloading assembly includes a horizontal slide 1061 and a unloading slide 1062; the unloading slide 1062 is arranged below the horizontal slide 1061, and intersects and communicates with the horizontal slide 1061. Among them, the horizontal slide 1061 is arranged horizontally, and the intersection of the unloading slide 1062 and the horizontal slide 1061 means that the unloading slide 1062 is vertically arranged or inclined, that is, the two are not parallel or overlapping. Among them, the support frame 106 can be arranged on the mixing frame 101.

[0085] The mixing box 112 is slidably mounted on the horizontal slide 1061 via a slider 127. The unloading slide 1062 allows the slider 127 to enter, tilting the mixing box 112 forward. Specifically, the horizontal slide 1061 allows the mixing box 112 to slide and adjust its horizontal position; the sliding control of the mixing box 112 can be automated or manual. After the mixing box 112 completes mixing, the slider 127 is pulled to the unloading slide 1062 position, allowing the slider 127 to slide into the unloading slide 1062. It should be noted that the sliding member 127 can be located near the front end of the mixing box 112, so that when the sliding member 127 slides into the mixing box 112, the mixing box 112 tilts toward the front end; and the sliding member 127 can always be located in the discharge chute 1062, and the mixing box 112 can adjust its position along the horizontal slide 1061 relative to the stationary sliding member 127, specifically, the sliding member 127 can slide along the discharge chute 1062 to adjust the horizontal inclination angle of the mixing box 112.

[0086] The front side of the mixing box 112 is equipped with an openable and closable opening. The trough 105 is located below the support frame 106, with an inlet at the top and an openable and closable outlet at the bottom. The inlet is used to receive material transferred out of the opening. When the mixing box 112 tilts forward, the opening remains open, allowing the mixed material inside to flow out of the mixing box and into the trough. The mixing box 112 is then controlled to slide out of the outlet chute 1062, return to a horizontal state, and slide through the horizontal slide 1061 to the position corresponding to the feed pipe 109, allowing the next round of feeding and mixing to begin.

[0087] The conveying mechanism 2 is arranged below the material trough 105, and is used to transfer the material transferred out of the discharge port to the pressing station and the inspection station; the pressing mechanism 3 is arranged on the pressing station, and is used to press the material into shape; the inspection mechanism 4 is arranged on the inspection station, and is used to inspect the material after pressing and forming.

[0088] Specifically, the feed pipe 109 is mounted on the main body of the device, and a corresponding openable and closable feed channel can be provided on the mixing box 112. When the mixing box 112 slides along the horizontal slide 1061 until the feed channel aligns with the feed pipe 109, the control terminal controls the feed pipe 109 to feed the material into the mixing box 112, then controls the mixing box 112 to begin stirring, and cooperates with the unloading assembly to automatically unload the material. The conveying mechanism 2 then transports the stirred material in the trough 105 to the pressing and testing stations for stamping, forming, and testing, achieving continuous automated production and improving production efficiency.

[0089] The above is Example 1 provided in the embodiments of this application, and the following is Example 2 provided in the embodiments of this application.

[0090] See also Figure 3 and Figure 4 Based on the above-mentioned embodiment 1, in this embodiment, the blanking assembly also includes: a blanking rotating member 110, a reset rotating member 132, a blanking elastic member 136, a reset elastic member 133 and a reset slide 1063; the top of the reset slide 1063 is connected to the horizontal slide 1061, and the bottom is connected to the blanking slide 1062; a triangular block 135 surrounded by the horizontal slide 1061, the blanking slide 1062 and the reset slide 1063 is provided on the support frame 106; the triangular block 135 and the support frame 106 are connected by a protruding connecting rod 131. One end of the unloading rotating member 110 can be rotatably connected to the bottom of the triangular block 135, and the other end abuts the lower sliding wall of the unloading slide 1062; the reset rotating member 132 is arranged horizontally, and one end can be rotatably connected to the support frame 106, and the other end abuts the top of the triangular block 135; the two ends of the unloading elastic member 137 are respectively connected to the unloading rotating member 110 and the support frame 106; the two ends of the reset elastic member 133 are respectively connected to the reset rotating member 132 and the support frame 106.

[0091] The return slide 1063 can be located at the front end of the unloading slide 1062, and both the unloading slide 1062 and the return slide 1063 are inclined toward the front end from top to bottom. The unloading rotating member 110 is used to restrict the sliding member 127 from sliding from the return slide 1063 into the unloading slide 1062; the return rotating member 132 is used to restrict the sliding member 127 from sliding from the horizontal slide 1061 into the return slide 1063.

[0092] In this embodiment, the mixing box 112 is fixedly connected to the sliding member 127; when the mixing box 112 is mixing, the sliding member 127 is located at the front end of the horizontal slide 1061, that is, above the reset slide 1063; after the mixing is completed, the mixing box 112 is controlled to slide to the rear end, passing through the reset rotating member 132 and sliding onto the discharge slide 1062. Because the other end of the reset rotating member 132 abuts the top of the triangular block 135, it cannot slide toward the reset slide 1063, so that the sliding member 127 can slide over the reset rotating member 132. Thereafter, the mixing box 112 is controlled to slide toward the front end and enter the discharge slide 1062 for tilting and unloading, and the sliding member 127 gradually slides to rotate the discharge rotating member 110 and enter the reset slide 1063. Among them, when the sliding member 127 abuts the bottom of the reset slide 1063, the material inside the mixing box 112 has just been dumped. The unloading rotating member 110 is then reset under the action of the unloading elastic member 136. The mixing box 112 is then moved rearward, passing the unloading rotating member 110 and sliding along the reset slide 1063 to the toggle reset rotating member 132, entering the horizontal slide 1061. The reset rotating member 132 is then restored to a horizontal position under the action of the reset elastic member 133, allowing the mixing box 112 to slide forward over the reset rotating member 132. Because the other end of the unloading rotating member 110 abuts the lower sliding wall of the unloading slide 1062, it cannot slide toward the unloading slide 1062. This allows the slider 127 to slide past the unloading rotating member 110 while sliding within the reset slide 1063.

[0093] The unloading assembly can provide propulsion force to the front and rear ends of the mixing box 112, causing the mixing box 112 to automatically tilt and unload, then return to a horizontal position to continue mixing, thereby achieving the purpose of automated mixing and unloading. It should be noted that the unloading elastic member 136 can be connected to the unloading telescopic rod 137; the reset elastic member 133 can be connected to the reset telescopic rod 134.

[0094] As a further improvement, in this embodiment, the mixing boxes include two, namely the mixing box 112 and the second mixing box 107; the corresponding blanking components include two; the mixing box 112 and the second mixing box 107 are symmetrically arranged; the two blanking components are symmetrically arranged.

[0095] The front ends of the mixing box 112 and the second mixing box 107 are the ends facing each other. A sealing ring 111 is provided at the front end of the mixing box 112, and a second sealing ring 108 is provided at the front end of the second mixing box 107. When the sealing ring 111 and the second sealing ring 108 are connected, the opening is sealed; when the sealing ring 111 and the second sealing ring 108 are separated, the opening is open.

[0096] Specifically, the mixing box 112 and the second mixing box 107 can slide horizontally in the horizontal slide 1061 in their respective corresponding unloading assemblies. When preparing for mixing, the mixing box 112 and the second mixing box 107 slide toward each other until the sealing ring 111 and the second sealing ring 108 are connected. At this time, the through-ports at the front ends of the mixing box 112 and the second mixing box 107 are sealed and connected to each other to reach a closed state. After the mixing is completed, the mixing box 112 and the second mixing box 107 move away from each other, so that the through-ports are opened, and the materials inside the mixing box 112 and the second mixing box 107 will partially flow out into the material trough 105. After the mixing box 112 and the second mixing box 107 slide into their respective corresponding unloading chutes 1062, after all the internal materials are discharged, they are reset to a horizontal state and re-sealed and connected, and the next feeding and mixing can be carried out.

[0097] Accordingly, the sealing ring 111 may be provided with a plurality of latches, and the second sealing ring 108 may be provided with a plurality of slots adapted to the latches. An inlet channel for feeding may be provided on the second mixing box 107 .

[0098] Furthermore, a stirring shaft 125 is provided inside the stirring box 112 and the second stirring box 107 ; a clamping block for clamping with another stirring shaft 125 is provided at the front end of the stirring shaft 125 .

[0099] Specifically, the front end of the stirring shaft 125 inside the stirring box 112 can be a tapered bump; the front end of the stirring shaft 125 inside the second stirring box 107 can be a tapered groove corresponding to the tapered bump. When the stirring boxes 112 and the second stirring box 107 are brought into contact with each other, the two stirring shafts 125 engage through the tapered bump and the tapered groove, achieving a synchronous transmission connection. This allows the rotation of any stirring shaft 125 to drive the synchronous rotation of the other stirring shaft 125, simplifying the overall transmission structure. The stirring shaft 125 can also be provided with multiple stirring rods 124.

[0100] See also Figure 5 In this embodiment, the sliding member 127 is a roller. Support bases 126 are provided at the front and rear ends of the bottoms of the mixing box 112 and the second mixing box 107. The sliding member 127 is rotatably mounted on the support base 126, thereby allowing it to slide along the horizontal slide 1061. When the mixing box needs to rotate, the sliding member 127 at the rear end serves as the center of rotation.

[0101] See also Figure 5 and Figure 6The outside of the mixing box 112 or the second mixing box 107 can be connected to a mixing transmission assembly. In this embodiment, the mixing transmission assembly includes: a motor bracket 128 and a mixing motor 113. The motor bracket 128 is arranged on the outside of the mixing box 112 for mounting the mixing motor 113. The mixing shaft 125 corresponding to the mixing box 112 is externally synchronously connected to the transmission shaft 121; the transmission shaft 121 is connected to the motor bevel gear 122 through the transmission bevel gear 123; the motor bevel gear 122 is connected to the mixing motor 113 through the transmission.

[0102] Furthermore, the mixing and discharging mechanism 1 also includes: a sliding control component. In this embodiment, the sliding control of the mixing box 112 and the second mixing box 107 is achieved through the sliding control component. The sliding control component includes: a sliding driver 116, a sliding gear 117, a first rack 115 and a second rack 118; the first rack 115 and the second rack 118 are respectively fixedly connected to the second mixing box 107 and the mixing box 112; the sliding gear 117 is simultaneously meshed with the first rack 115 and the second rack 118; the sliding driver 116 is in transmission connection with the sliding gear 117, and is used to drive the second mixing box 107 and the mixing box 112 to move closer to and away from each other.

[0103] Specifically, a first connecting rod 129 is fixedly connected to the rear end of the mixing box 112. A second connecting rod 130 is fixedly connected to the rear end of the second mixing box 107. The first connecting rod 129 is rotatably connected to the second rack 118, while the second connecting rod 130 is rotatably connected to the first rack 115.

[0108] See also Figure 9 and Figure 10 In this embodiment, the pressing mechanism 3 includes: a pressing block 313 and a punching block 306; the pressing block 313 is movably arranged above the pressing station in the vertical direction, and is used to press the material in the hopper 204; the punching block 306 is movably arranged above the punching station in the vertical direction, and is used to punch the material in the hopper 204 out to the detection belt 409.

[0109] See also Figure 11 In this embodiment, the detection mechanism 4 includes: a detection belt 409 and a detector 408; the detection belt 409 is located below the punching station and is used to transfer the material on the punching station to the detection station; the detector 408 is movably arranged on the detection station along the vertical direction.

[0110] Specifically, the detection belt 409 is rotatably mounted on the detection belt frame 407 via the detection belt shaft 405 and is in transmission connection with the detection belt motor 412 via the active rotating shaft 410. The detection belt motor 412 is mounted on the detection belt frame 407 via the detection belt support rod 411. The detection mechanism 4 may further include: a detector frame 401, a detector motor 403, a detection rod 402, a detector support rod 404, and a display rod 406.

The detector 408 is disposed at the bottom of the detection rod 402.

[0111] Multiple signal sensors can be installed on the display rod 406. Multiple silo sensors 413 are spaced apart on the detector rack 401 along the conveying direction of the detection belt 409, and the silo sensors 413 are symmetrically arranged on both sides of the detection belt 409. Accordingly, multiple detectors 408 can be provided, evenly spaced to correspond to the spacing of the silos 204. When the concrete brick is knocked down onto the detection belt 409 by the punch block 306, the output shaft of the detection belt motor 412 drives the active shaft 410 to rotate, and the active shaft 410 drives the detection belt shaft 405 to rotate through the detection belt 409, and the detection belt 409 drives the concrete brick to move. When all the silo sensors 413 on the detector rack 401 sense the concrete brick, the silo sensor 413 sends a signal to stop the detection belt motor 412 and start the detector motor 403 at the same time. The piston rod of the detector motor 403 drives the detection rod 402 to slide on the detector rack 401, and the detection rod 402 drives the detector 408 to move. When the detector 408 contacts the concrete brick, it detects Resistance, the resistance value is fed back to the display rod 406. When the resistance value is displayed on the display rod 406, the signal sensor on the display rod 406 sends a signal to make the piston rod of the detector motor 403 drive the detection rod 402 to slide in the opposite direction on the detector frame 401, and at the same time start the detection belt motor 412, the detection rod 402 drives the detector 408 to move in the opposite direction, and the output shaft of the detection belt motor 412 drives the active rotating shaft 410 to rotate, and the active rotating shaft 410 drives the detection belt shaft 405 to rotate through the detection belt 409. The detection belt 409 transports the concrete brick away and transports the next concrete brick to the bottom of the detector 408 for measurement, thereby completing the measurement of the conductive performance of the concrete.

[0113] Specifically, the stamping motor 303, connecting rod 305, and slide bar 309 form a crank-connecting rod mechanism, whereby the rotation of the stamping motor 303 drives the punch 306 and pressure block 313 to slide vertically. A stamping spring 311 may be provided between the pressure block 313 or the punch 306 and the stamping frame 301. The stamping transmission assembly may further include a crossbar 308. The crossbar 308 is fixedly connected at its ends to the first driven rod 307 and the second driven rod 310, respectively, and at its center to the slide bar 309. The slide bar 309 may be fixedly connected to a slider 314; the slider 314 is slidably mounted on a slide plate 315; the slide plate 315 is fixedly mounted on the stamping frame 301. The stamping motor 303 is mounted on the device body 5 via the stamping support plate 302. An outer rod 312 may be sleeved on the bottom of the second driven rod 310, and the stamping spring 311 is sleeved on the outer rod 312. In addition, both the punch block 306 and the pressure block 313 may be provided with a silo sensor and a pressure sensor.

[0114] When the hopper 204 moves to the bottom of the pressing block 313, the hopper sensor on the pressing block 313 sends a signal to stop the conveyor motor 201 and start the punching motor 303 at the same time. The output shaft of the punching motor 303 drives the eccentric wheel 304 to rotate, and the eccentric wheel 304 drives the connecting rod 305 to move. The connecting rod 305 drives the slider 314 to slide in the slide plate 315 through the sliding rod 309. The sliding rod 309 drives the first driven rod 307 and the second driven rod 310 to slide on the punching frame 301 through the cross rod 308. The second driven rod 310 drives the pressing block 313 to move through the outer rod 312. The pressing block 313 squeezes the concrete in the hopper 204 to form concrete bricks after squeezing.

[0115] The pressure sensor on the outer rod 312 sends a signal to make the output shaft of the stamping motor 303 drive the eccentric wheel 304 to rotate in the opposite direction. The eccentric wheel 304 drives the connecting rod 305 to rotate in the opposite direction. The connecting rod 305 drives the slider 314 to slide in the opposite direction in the slide plate 315 through the sliding rod 309. The sliding rod 309 drives the first driven rod 307 and the second driven rod 310 to slide in the opposite direction on the stamping frame 301 through the cross rod 308. The second driven rod 310 drives the pressure block 313 to move in the opposite direction through the outer rod 312.

[0116] When the hopper 204 drives the concrete bricks to move to the hollow position on the bottom plate 208 corresponding to the punching station, the punching motor 303 is started, and the punching motor 303 drives the punching block 306 to move. The punching block 306 punches the concrete bricks in the hopper 204 out of the hopper 204. The concrete bricks pass through the hollow position on the bottom plate 208 and fall onto the detection belt 409. The signal sensor on the punching block 306 sends a signal to cause the output shaft of the punching motor 303 to drive the eccentric wheel 304 to rotate in the opposite direction until the punching block 306 is reset. The punching block 306 and the pressing block 313 are arranged at intervals, and the interval can be consistent with the interval between adjacent hoppers 204.

[0117] Further, see Figure 3 The discharge port of the trough 105 is controlled by the port opening and closing assembly. The port opening and closing assembly includes: a port motor 102, a port connecting rod 103, and a partition 104. The partition 104 is movably arranged on the discharge port; the port motor 102 is connected to the partition 104 through the port connecting rod 103, and controls the opening and closing of the discharge port by controlling the partition 104 to approach and move away from the discharge port. At the same time, a silo sensor can be set on the trough 105. When the silo 204 is about to pass under the trough 105, the silo sensor sends a signal to make the port motor 102 open the discharge port; when the silo 204 is about to move away, the silo sensor sends a signal to make the port motor 102 close the discharge port, thereby realizing automatic filling.
