DETAILED DESCRIPTION

In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

As shown in Fig. 1-6, a construction sand and gravel mixing device includes a mixing box 2, a driving component is arranged inside the mixing box 2, a moving component is arranged on the driving component, and a feeding pipe 1 is arranged on the top of the mixing box.

Furthermore, the mixing box 2 is composed of a cylindrical shell and a conical shell. The cylindrical shell can stir the material, and the conical shell can discharge the stirred material without clogging. A discharge port is provided at the bottom of the cylindrical shell, and a control valve in the prior art can be provided on the discharge port to control the discharge of the material.

Furthermore, the mixing box 2 can be mounted on an external support frame for fixation, and a water inlet (marked in the figure) can be opened on the mixing box 2.

A slide groove 3 is provided on the inner wall of the mixing box 2, a slider 4 is slidably arranged in the slide groove 3, the slide groove 3 matches the slider 4, a carrier plate 5 with a conical surface is fixedly arranged on the slider 4, and a first through hole 6 is provided at the center of the carrier plate 5.

Furthermore, the top surface of the carrier plate 5 is conical and the bottom surface is circular. The top surface can ensure smooth discharge of the material after stirring is completed, and the diameter of the carrier plate 5 matches the diameter of the mixing box 2, thereby preventing leakage of the material during stirring.

Furthermore, a plurality of slide grooves 3 and corresponding sliders 4 can be provided, and it is only necessary to ensure that the lifting plate 8 can drive the carrying plate 5 to move up and down smoothly.

The moving component includes a connecting rod 7 arranged at the bottom of the driving component, the connecting rod 7 is located inside the first through hole 6, and a thread is provided on the connecting rod 7, a lifting plate 8 is sleeved on the thread, a limiting rod 9 is movably provided on the lifting plate 8, the top of the limiting rod 9 is connected to the supporting plate 5, and a conical sealing block 10 matching the first through hole 6 is provided on the top of the lifting plate 8, and the cross-sectional area of the lifting plate 8 is larger than the cross-sectional area of the first through hole 6.

First, the material is allowed to enter the inner space of the mixing box 2 through the feed pipe 1. At this time, the internal structure design is shown in Figure 5. The conical sealing block 10 is located in the first through hole 6 for sealing, and the lifting plate 8 is in contact with the supporting plate 5, so that the conical sealing block 10 and the supporting plate 5 form a plate that can carry the material. Then the material is stirred by the driving component. During stirring, the driving component drives the connecting rod 7 to rotate. Because the lifting plate 8 is limited by the limiting rod 9, the lifting plate 8 will not rotate, and the lifting plate 8 will only move upward through the thread on the connecting rod 7. Because the lifting plate 8 is in contact with the supporting plate 5, when the lifting plate 8 moves upward, it will drive the supporting plate 5 to move the slider 4 in the slide groove 3, thereby driving the material on the supporting plate 5 to move upward. At this time, the driving component does not move. When the material moves upward, the material at the bottom that has not been stirred can also be stirred by the driving component, so that the material can be stirred at various positions, thereby improving the stirring effect.

As shown in Figure 6, after the mixing is completed, the driving assembly drives the connecting rod 7 to reverse, because the lifting plate 8 is limited by the limiting rod 9, so that the lifting plate 8 will not rotate and can move downward on the connecting rod 7, and the supporting plate 5 will also move downward in the slide groove 3 through the slider 4, but the slide groove 3 will limit the slider 4. When it reaches this position, the supporting plate 5 will not move, and then the lifting plate 8 drives the conical sealing block 10 to be pulled out from the first through hole 6. At this time, the material will flow out of the first through hole 6 through the conical surface of the supporting plate 5, and then the inclined surface of the conical sealing block 10 will make the material flow smoothly without blockage. Then the mixed material flows out of the mixing box 2, thereby ensuring the normal mixing and processing of the material and improving the processing effect.

It should be noted that a second limiting plate can be provided on the connecting rod 7 to limit the upward and downward movement space of the lifting plate 8, thereby ensuring that the lifting plate 8 does not exceed the formation and cause damage to the entire device.

Furthermore, when the lifting plate 8 drives the carrying plate 5 to move, the stirring space inside it will also be reduced, which can ensure stirring at each position and improve the stirring effect.

Furthermore, the conical surface of the carrier plate 5 allows the stirring rod 13 to enter and contact without causing interference, thereby stirring the material at the bottom.

A first limiting plate is provided at the bottom of the limiting rod 9, and the first limiting plate is provided to ensure that the lifting plate 8 will not exceed the formation and cause damage to the entire device.

As shown in Figure 2, the driving assembly includes a motor 11 arranged on the top of the mixing box 2, the output end of the motor 11 is connected to the rotating shaft 12, the end of the rotating shaft 12 away from the motor 11 passes through the mixing box 2 and is connected to the connecting rod 7, and a plurality of stirring rods 13 are staggered on the outside of the rotating shaft 12, and a cleaning brush is provided on the side of the stirring rod 13 close to the mixing box 2.

The motor 11 drives the rotating shaft 12 to make the stirring rod 13 stir the material inside the stirring box 2, and at the same time can drive the connecting rod 7 to rotate. After the material is stirred, the cleaning water is heated to drive the cleaning brush to clean the inner wall of the stirring box 2.

Furthermore, the motor 11 of the utility model is a reciprocating stepping motor, and the rotating shaft 12 and the connecting rod 7 can be fixedly connected, such as welding, and the fixed connection can make the device more stable, or can be a movable connection, such as a bolt connection, and the movable connection can make the entire device disassembled and replaced.

The working principle of the utility model is as follows: firstly, the material is allowed to enter the inner space of the mixing box 2 through the feed pipe 1. At this time, the internal structure design is shown in Figure 5. The conical sealing block 10 is located in the first through hole 6 for sealing. The lifting plate 8 contacts the supporting plate 5, so that the conical sealing block 10 and the supporting plate 5 form a plate that can carry the material. The motor 11 drives the rotating shaft 12 to make the stirring rod 13 stir the material inside the mixing box 2, and at the same time, it can drive the connecting rod 7 to rotate. Because the lifting plate 8 is limited by the limiting rod 9, the lifting plate 8 will not rotate, and the lifting plate 8 will only be moved upward by the thread on the connecting rod 7. Because the lifting plate 8 is in contact with the supporting plate 5, when the lifting plate 8 moves upward, it will drive the supporting plate 5 to move the slider 4 in the slide groove 3, thereby driving the material on the supporting plate 5 to move upward. At this time, the driving component does not move. When the material moves upward, the material that has not been stirred at the bottom can also be stirred by the driving component, so that the material can be stirred at various positions, thereby improving the stirring effect.

As shown in Figure 6, after the stirring is completed, the motor 11 drives the rotating shaft 12 to make the stirring rod 13 stir the material inside the mixing box 2, and at the same time drive the connecting rod 7 to reverse, because the lifting plate 8 is limited by the limiting rod 9, so that the lifting plate 8 will not rotate and can move downward on the connecting rod 7, and then the lifting plate 8 drives the conical sealing block 10 to be drawn out from the first through hole 6. At this time, the material will flow out of the first through hole 6 through the conical surface of the supporting plate 5, and then the inclined surface of the conical sealing block 10 will make the material flow smoothly without blockage. Subsequently, the stirred material flows out of the mixing box 2, thereby ensuring the normal stirring and processing of the material and improving the processing effect.

The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
