Description

Technical Field

[0001] The utility model belongs to the field of concrete processing, in particular to a visualized water reducing agent filling device for a concrete tank truck. Background Art

[0002] Adding water reducer to concrete tank truck is the process of adding water reducer during concrete mixing to improve the fluidity and working performance of concrete. Generally, water reducer can make concrete easier to pump, pour and vibrate, while also reducing the water-cement ratio of concrete and improving the strength and durability of concrete.

[0003] In the prior art, when adding water reducer to a concrete tank truck, workers usually climb to the filling port and then manually fill the tank with water reducer. However, when manually adding water reducer, workers' hands cannot support their bodies, which may cause certain dangers. In addition, workers only fill the tank truck based on experience and cannot accurately control the amount of water reducer. If the amount of water reducer added is too much or too little, it will affect the fluidity and working performance of the concrete, and even affect the strength and durability of the concrete, thereby reducing the service life of the concrete.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figure 1-5 A visual filling device for a water reducing agent for a concrete tank truck comprises a storage box 3, a connecting pipe 5 is fixedly connected to the top of the storage box 3, a fixing plate 6 is fixedly connected to the side of the connecting pipe 5 away from the storage box 3, a camera 7 is installed on one side of the bottom of the fixing plate 6, a filling gun 8 is fixedly connected to the side of the bottom of the fixing plate 6 close to the camera 7, a filling pipe 11 is slidably connected to the top of the filling gun 8, filling holes 12 are provided on both sides of the inner wall of the filling pipe 11, inner holes 13 matching with the filling holes 12 are provided on both sides of the bottom of the filling gun 8 close to the filling hole 12, a turntable 9 is rotatably connected to the bottom of the filling gun 8, a nozzle 10 is fixedly connected to the bottom of the turntable 9 at equal intervals, an adjustment component is provided on the top of the filling gun 8, and a transmission component is provided on the outside of the filling gun 8.

[0023] Specifically, the adjustment component includes a servo motor 14, which is fixedly connected to an external side of the filling gun 8. The output end of the servo motor 14 extends to the inside of the filling gun 8 and is fixedly connected to a cam 15. Springs 16 are provided between the top sides of the filling pipe 11 and the inner wall of the filling gun 8. The outside of the output end of the servo motor 14 is fixedly connected to a first pulley 17. A rotating rod 18 is rotatably connected to the lower outside of the filling gun 8. A second pulley 19 is fixedly connected to an external side of the rotating rod 18. The first pulley 17 and the second pulley 19 are connected for transmission via a transmission belt 20. A first bevel gear 21 is fixedly connected to the top of the turntable 9. A second bevel gear 22 is fixedly connected to the external side of the rotating rod 18 close to the first bevel gear 21. The first bevel gear 21 is meshingly connected to the second bevel gear 22.

[0024] Through the above technical solution, when it is necessary to add water reducing agent to the interior of the concrete tank truck, the water pump 4 is started through the external controller, and the water pump 4 draws the water reducing agent in the storage box 3 into the interior of the filling gun 8, and at the same time the servo motor 14 is started, and the output end of the servo motor 14 drives the cam 15 to rotate, and the cam 15 can repeatedly push the filling pipe 11 downward during the rotation process, and the rebound force of the spring 16 can make the filling pipe 11 reciprocate and rise and fall, thereby driving the filling holes 12 on both sides to reciprocate and rise and fall, and after the filling hole 12 is lowered, it is aligned with the inner hole 1 3 overlaps, so that the water reducing agent inside the filling pipe 11 can be circulated, and then sprayed into the interior of the concrete tanker through the nozzle 10 at the bottom of the turntable 9. When the amount of water reducing agent to be added needs to be adjusted, the speed and stop time of the servo motor 14 are adjusted to slow down the speed of the servo motor 14, and when the cam 15 pushes the filling pipe 11 to move to the bottom, it stops appropriately, so as to increase the filling amount of the water reducing agent. When the filling amount needs to be reduced, it is the opposite, so as to accurately control the filling amount of the water reducing agent. At the same time, the servo motor 14 is running. When the concrete tank is in operation, the first pulley 17 can be driven to rotate through the output end, so that the first pulley 17 drives the second pulley 19 and the rotating rod 18 to rotate through the transmission belt 20, and the rotating rod 18 drives the second bevel gear 22 to rotate, so that the second bevel gear 22 drives the first bevel gear 21 to rotate through the meshing relationship, that is, the turntable 9 at the bottom is driven to rotate through the first bevel gear 21, so that the turntable 9 drives the nozzle 10 to rotate when the water reducer is added, so that the water reducer is evenly sprayed into the interior of the concrete tank truck, thereby improving the uniformity of the filling of the water reducer, making the mixing of the water reducer and the concrete more sufficient, thereby improving the filling efficiency. The device can adjust and control the filling amount of the water reducer through the cooperation between the provided filling hole 12 and the inner hole 13, and the filling amount can be more accurately controlled than the manual filling of the water reducer, thereby ensuring that the fluidity and working performance of the concrete are in the best state. At the same time, the provided camera 7 can facilitate the staff to remotely observe the interior of the concrete tank truck, replacing manual climbing and naked eye observation, thereby improving safety.

[0025] Specifically, the nozzle 10 is connected to the inner hole 13 through an internal channel, the nozzle of the nozzle 10 is set to be inclined outward, a bellows 23 is arranged between the top of the filling pipe 11 and the bottom of the fixed plate 6, the connecting pipe 5 and the bellows 23 are connected through an internal channel, a water inlet is arranged on the external side of the storage box 3, a water pump 4 is installed outside the connecting pipe 5 and at the top of the storage box 3, a placement seat 2 is fixedly connected to the bottom of the storage box 3, a base 1 is arranged at the bottom of the placement seat 2, a cylinder is installed inside the base 1, and the placement seat 2 is fixedly connected to the output end of the cylinder.

[0026] Through the above technical solution, the bellows 23 can better cooperate with the filling pipe 11 to perform frequent up and down movements, and the storage box 3 can be raised and lowered arbitrarily by controlling the extension and retraction of the output end of the cylinder, so as to facilitate adaptation to concrete tank trucks of different heights, further improving the practicality of the device.

[0027] Specifically, the camera 7 is electrically connected to the external display screen through an external controller, and the servo motor 14 and the water pump 4 are both electrically connected to the external controller.

[0028] Through the above technical solution, the staff can quickly control the servo motor 14 and the water pump 4 through the external controller.

[0029] When it is needed to add water reducing agent to the interior of the concrete tank truck, the water pump 4 is started through the external controller, and the water pump 4 draws the water reducing agent in the storage box 3 into the interior of the filling gun 8, and the servo motor 14 is started at the same time. The output end of the servo motor 14 drives the cam 15 to rotate. The cam 15 can repeatedly push the filling pipe 11 downward during the rotation process, and the rebound force of the spring 16 can make the filling pipe 11 reciprocate and rise and fall, thereby driving the filling holes 12 on both sides to reciprocate and rise and fall. After the filling holes 12 are lowered, they are in contact with the filling holes 12. The inner holes 13 overlap, so that the water reducing agent inside the filling pipe 11 can be circulated, and then sprayed into the interior of the concrete tanker through the nozzle 10 at the bottom of the turntable 9. When the amount of water reducing agent to be filled needs to be adjusted, the speed and stop time of the servo motor 14 are adjusted to slow down the speed of the servo motor 14, and when the cam 15 pushes the filling pipe 11 to move to the bottom, it stops appropriately, so as to increase the filling amount of the water reducing agent, and vice versa when the filling amount needs to be reduced, so as to accurately control the filling amount of the water reducing agent, and at the same time When the servo motor 14 is running, it can drive the first pulley 17 to rotate through the output end, so that the first pulley 17 drives the rotating rod 18 to rotate through the second pulley 19 and the transmission belt 20, and the rotating rod 18 drives the second bevel gear 22 to rotate, so that the second bevel gear 22 drives the first bevel gear 21 to rotate through the meshing relationship, that is, the turntable 9 at the bottom is driven to rotate through the first bevel gear 21, so that the turntable 9 drives the nozzle 10 to rotate when the water reducer is added, so that the water reducer is evenly sprayed into the interior of the concrete tank truck, the filling uniformity of the water reducer is improved, and the mixing of the water reducer and the concrete is more sufficient, thereby improving the filling efficiency. The bellows 23 provided can better cooperate with the filling pipe 11 to perform frequent up and down movements. The storage box 3 can be arbitrarily lifted and lowered by controlling the extension and retraction of the output end of the cylinder, so as to facilitate the adaptation of concrete tank trucks of different heights, further improving the practicality of the device, and the staff can quickly control the servo motor 14 and the water pump 4 through the external controller.
