DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, a mud material homogenizing device provided by an embodiment of the present invention comprises two frames 1 arranged at intervals, the two frames 1 are fixedly connected by a crossbeam 2, and further comprises: The sliding assembly includes slide rails 3 respectively fixedly connected to the tops of the two frames 1, and the two slide rails 3 are matched with electric slide seats 4 in a spanning state, and a telescopic mixing box 5 is fixedly connected to the electric slide seat 4. The telescopic mixing box 5 can adjust its height in the vertical direction, and a discharge assembly 6 is provided at the bottom of the telescopic mixing box 5; A stirring assembly is arranged on two frames 1. The stirring assembly includes a frame 7 fixedly connected to the frames 1 on both sides. A stirrer 8 in a vertical state is rotatably connected to the top of the frame 7. A driving member 9 for driving the stirrer 8 to rotate is fixedly arranged on the frame 7. The driving member 9 can be in the form of an electric motor, or of course, in the form of a hydraulic motor, in order to drive the stirrer 8 to rotate; The two ends of the frame 1 along its own length direction are respectively a working end and a cleaning end, and the stirrer 8 is arranged close to the working end.

[0019] In one embodiment of the present invention, the device utilizes a telescopic mixing box 5 to mix mud. The telescopic mixing box 5 can be controlled to move horizontally by an electric slide 4. When the telescopic mixing box 5 is unfolded, the agitator 8 is located in the telescopic mixing box 5. After the mud is added, mixing and stirring can be carried out. When the mixing is completed, the mud can be discharged through the discharge component 6. During the discharge process, the telescopic mixing box 5 is in a retracted state. By reducing the inner wall area of ​​the telescopic mixing box 5, the amount of mud adhesion can be reduced. When the telescopic mixing box 5 moves to the cleaning end, the telescopic mixing box 5 can be cleaned more conveniently. In summary, the device utilizes a telescopic structure to mix mud, which can be more efficient in mud discharge and device cleaning.

[0020] In one embodiment of the present invention, Figure 4 As shown, the electric slide 4 includes a driving slider 401 and a horizontally arranged cross frame 402 respectively located on the slide rails 3 of the two frames 1, and the telescopic mixing box 5 is installed on the cross frame 402. The driving slider 401 is used to drive the cross frame 402 to move between the working end and the cleaning end of the frame 1. The driving slider 401 adopts conventional means in the prior art, and its main purpose is to drive the cross frame 402 to move back and forth laterally, so it is not described in detail. A support column 15 located in the middle of the slide rail 3 is fixedly connected to the frame 1, and the top of the support column 15 is fixedly connected to the slide rail 3. Because the slide rail 3 itself is relatively long, the support column 15 can increase the supporting effect of the frame 1 on the slide rail 3, and can avoid deformation of the slide rail 3 itself, thereby making the telescopic mixing box 5 more stable during movement.

[0021] like Figure 4 , Figure 5 and Figure 6 As shown, as a preferred embodiment of the present invention, the telescopic stirring box 5 includes a first annular box body 501 fixedly connected to the horizontal frame 402, the diameter of the first annular box body 501 is larger than the rotation profile diameter of the stirrer 8, the discharge assembly 6 is installed on the horizontal frame 402 and is located at the bottom of the first annular box body 501, and the second annular box body 502 and the third annular box body 503 are sequentially arranged on the outside of the first annular box body 501, and the top edge of the first annular box body 501 is fixedly connected to the second annular box body. A first sealing ring 504 is fitted with the inner wall of 502, and a second sealing ring 505 is fixedly connected to the bottom edge of the second annular box body 502 and fits with the outer wall of the first annular box body 501, and a structure identical to the first sealing ring 504 and the second sealing ring 505 is arranged between the second annular box body 502 and the third annular box body 503, and both ends of the cross frame 402 are fixedly connected with a vertically arranged first telescopic member 10, and a side plate 11 connected to the third annular box body 503 is fixed to the top of the first telescopic member 10.

[0022] In one case of the present embodiment, the length of the cross frame 402 is greater than the distance between the two slide rails 3, and the distance between the two first telescopic members 10 is also greater than the distance between the two slide rails 3. The working end of the frame 1 is fixedly connected to a support frame 12 which is in a vertical state and is arranged toward the cleaning end. The support frame 12 and the frame 1 are in the same plane. The bottom of the side plate 11 is fixedly connected to a cushion block 13 corresponding to the position of the support frame 12. When the cross frame 402 moves toward the agitator 8 at the working end, the first telescopic member 10 is used to drive the third annular box 503 to move in the vertical direction. When the cushion block 13 moves onto the support frame 12, the cross frame 402 is located at the working end of the frame 1. The stirrer 8 is located in the first annular box body 501. When the cushion block 13 is located on the support frame 12, the first annular box body 501 and the stirrer 8 are in a coaxial state. The function of the support frame 12 is to provide support for the telescopic stirring box 5. When stirring and mixing, the first telescopic member 10 does not need to keep working continuously. First, the telescopic stirring box 5 will move to a state corresponding to the stirrer 8, but the stirrer 8 is not located at the center of the telescopic stirring box 5 at this time. When the telescopic stirring box 5 needs to be opened, the third annular box body 503 is driven upward by the first telescopic member 10. When all the first sealing rings 504 and the second sealing rings 505 are in contact, it will appear as follows Figure 7 In the state shown, the telescopic mixing box 5 presents a shape suitable for mud mixing, and the electric slide seat 4 will control the telescopic mixing box 5 to move horizontally a certain distance, so that the pad 13 is located on the support frame 12 for mud mixing. When the mud is discharged, the mud in the telescopic mixing box 5 will continue to decrease, but a large amount of mud will be attached to the inner wall. At this time, if the third annular box body 503 is controlled to move downward by the first telescopic member 10, the mud on the inner walls of the first annular box body 501 and the second annular box body 502 will be scraped off, which is beneficial to the discharge of the mud. When the telescopic mixing box 5 is fully retracted, its own height is greatly reduced, and when it is located at the cleaning end of the frame 1, the agitator 8 and the telescopic mixing box 5 are in a separated state, which is undoubtedly more convenient for cleaning the agitator 8 or the telescopic mixing box 5.

[0023] like Figure 5 As shown, as a preferred embodiment of the present invention, the bottom of the first annular box body 501 is a conical structure, and a discharge port 14 is provided at the bottom of the first annular box body 501, and the discharge assembly 6 includes a mounting plate 601 fixedly connected to both sides of the bottom of the cross frame 402, and the mounting plate 601 is fixedly connected to a second telescopic member 602, and a cross plate 603 that fits the discharge port 14 is fixedly connected between the two second telescopic members 602, and a circular hole is provided on the cross plate 603, and a discharge pipe 604 corresponding to the position of the circular hole is fixedly connected to the bottom of the cross plate 603, and the second telescopic member 602 is used to drive the cross plate 603 to move in a horizontal direction.

[0024] In one case of the present embodiment, the second telescopic member 602 and the first telescopic member 10 can be in the same form, such as a hydraulic telescopic rod, an electric telescopic rod, as long as they can drive the corresponding structure to perform linear motion. The second telescopic member 602 can control the cross plate 603 to move laterally. When the circular hole is aligned with the discharge port 14, the mud will enter the discharge pipe 604 from the third annular box 503. When the circular hole and the discharge port 14 are in an offset state, the cross plate 603 will close the discharge port 14, so that the mud in the third annular box 503 cannot be discharged.

[0025] The embodiment of the present invention further provides a method for uniformly mixing clay materials, the method comprising the following steps: Step 1: The telescopic mixing box 5 is driven to move toward the working end by the electric slide 4, so that the agitator 8 corresponds to the position of the first annular box 501, and the first telescopic member 10 is controlled to drive the third annular box 503 to move upward, so that the telescopic mixing box 5 is unfolded, and the electric slide 4 and the first telescopic member 10 are adjusted so that the cushion block 13 is located on the support frame 12, and the agitator 8 is located at the center of the telescopic mixing box 5; Step 2: Add the raw materials of the mud material into the telescopic mixing box 5, and mix the mud material using the stirrer 8; Step 3: After the mud material is mixed, the second telescopic member 602 controls the horizontal plate 603 to move so that the discharge pipe 604 is aligned with the discharge port 14, and then the mud material in the telescopic mixing box 5 is discharged; Step 4: When a large amount of mud remains on the inner wall of the telescopic mixing box 5 and cannot be discharged, the telescopic mixing box 5 is restored to the state at the cleaning end through the electric slide 4 and the first telescopic member 10.

[0026] In one case of the present embodiment, the present method utilizes a telescopic mixing box 5 to mix mud. The electric slide 4 can control the lateral movement of the telescopic mixing box 5. When the telescopic mixing box 5 is unfolded, the agitator 8 is located in the telescopic mixing box 5. After mud is added, mixing and stirring can be carried out. When the mixing is completed, the mud can be discharged through the discharge assembly 6. During the discharge process, the telescopic mixing box 5 is in a retracted state. By reducing the inner wall area of ​​the telescopic mixing box 5, the amount of mud adhesion can be reduced. When the telescopic mixing box 5 moves to the cleaning end, the telescopic mixing box 5 can be cleaned more conveniently. In summary, the use of a telescopic structure to mix mud can achieve more efficient mud discharge and device cleaning.
