In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] like Figure 1-5 As shown, an embodiment of the utility model provides a cement slurry mixer that is easy to clean, comprising a base 1, a column 11 fixedly connected to the base 1, a support seat 12 that can move along the height direction of the column 11, a stirring pot 3, a driving unit, and a stirring blade 23 installed at the output end of the driving unit, a limiting column 32 is installed at the lower part of the stirring pot 3, a plug-in block 321 is arranged at the middle part of the limiting column 32 along its own radial direction, a plug-in hole for the limiting column 32 to be plugged in is provided on the support seat 12, and a plug-in groove 122 that matches the plug-in block 321 is provided on the inner wall of the plug-in hole; an adjusting member is also included, and the adjusting member drives the plug-in block 321 to form a match with the plug-in groove 122; when the support seat 12 drives the stirring pot 3 to move vertically to the highest point, the stirring pot 3 reaches the stirring height.

[0029] Specifically, the base 1 is a flat plate, which is used to increase the contact area between the column 11 and the placement table so that the device can be placed stably. The column 11 is the main structure of the device, which is used to support the support seat 12 and the driving part. The stirring height refers to the height of the stirring pot 3 when the stirring blade 23 rotates to stir the cement and water in the stirring pot 3. Optionally, the driving part is a motor 2, and the stirring blade 23 is installed at the output end of the motor 2. When preparing for mixing, first add the weighed water and cement to the stirring pot 3 in turn, and then plug the limit column 32 at the bottom of the stirring pot 3 into the plug hole to make the stirring pot 3 in a horizontal state, and then adjust the part The drive plug-in block 321 moves radially along the limit column 32 and is plugged into the plug-in groove 122 on the inner wall of the plug-in hole. The plug-in block 321 cooperates with the plug-in groove 122 to limit the axial movement of the limit column 32 itself. The plug-in hole cooperates with the restriction of the radial movement of the limit column 32, so that the stirring pot 3 can be fully fixed. Optionally, the adjusting member is a miniature electric push rod, and the plug-in block 321 is installed on the miniature electric push rod, and the miniature electric push rod is installed in the limit column 32, and is extended and retracted along the radial direction of the limit column 32, so as to push the plug-in block 321 toward the plug-in groove 122 opened on the plug-in hole, so that the plug-in block 321 cooperates with the plug-in groove 122.

[0030] In this embodiment, the position of the limit column 32 is limited by the cooperation between the plug-in block 321 and the plug-in groove 122, so as to fix the stirring pot 3. The operation is simple, and the force exerted by the stirring blade 23 on the stirring pot 3 during the stirring process has little effect on the cooperation between the plug-in block 321 and the plug-in groove 122, and the plug-in block 321 will not be damaged and the fixing of the stirring pot 3 cannot be cancelled.

[0031] Furthermore, a vertically arranged guide rail 111 is fixedly connected to the column 11, and the support seat 12 is slidably connected to the guide rail 111 through a slide seat 121. A locking assembly 13 is also provided on the column 11. When the slide seat 121 slides to the highest point along the guide rail 111, the locking assembly 13 locks the slide seat 121 on the guide rail 111.

[0032] Specifically, the support seat 12 is provided with a slot that matches the guide rail 111, and the slot limits the slide seat 121 from sliding along the length direction of the guide rail 111. Figure 1 In the vertical direction, optionally, the locking assembly 13 adopts the cooperation of a rocker and a protrusion, and the protrusion is installed on the rotating shaft of the rocker. When the rocker rotates, it can drive the protrusion to rotate synchronously, which is not shown in the figure. When the support seat 12 slides along the length direction of the guide rail 111 to the stirring height, the rocker is pulled to use the rocker to drive the protrusion to rotate, and the protruding position of the protrusion presses the part of the slide 121 on the inner side of the column 11 tightly, and other existing locking structures can also be used.

[0033] Furthermore, the driving part includes a motor 2, a reduction box 21 fixed to the housing of the motor 2, and a planetary mechanism 22 fixed to the housing of the reduction box 21. The motor 2, the reduction box 21 and the planetary mechanism 22 are transmission connected, and the stirring blade 23 is installed on the planetary wheel of the planetary mechanism 22.

[0034] Specifically, the motor 2, the reduction box 21 and the planetary mechanism 22 all adopt the existing technology. In the existing technology, the motor 2 is a dual-speed motor 2, that is, the motor 2 has two operating speeds, which can realize the adjustment of two different rotational speeds of the stirring blade 23, so as to improve the stirring effect of cement and water. The planetary mechanism 22 is composed of a sun gear, a planetary gear and an inner ring gear. This is the existing technology and is not repeated here. The output shaft of the motor 2 is connected to the input shaft of the reduction box 21 by driving, and the output shaft of the reduction box 21 is coaxially connected to the sun gear in the planetary mechanism 22. The stirring blade 23 is installed on the planetary gear. In this way, when the motor 2 drives the stirring blade 23 to rotate, the stirring blade 23 can revolve while rotating, and has a higher stirring efficiency.

[0035] Furthermore, a cover plate 24 is fixedly connected to the shell of the planetary mechanism 22 , and when the stirring pot 3 is at the stirring height, the cover plate 24 seals the opening of the stirring pot 3 .

[0036] Specifically, the cover plate 24 is directly mounted on the shell of the planetary mechanism 22, that is, when the planetary mechanism 22 drives the stirring blades 23 to rotate, the cover plate 24 always remains stationary. When preparing for stirring, the stirring pot 3 is moved to the stirring height, and the stirring pot 3 approaches the cover plate 24. When the stirring pot 3 reaches the stirring height, the cover plate 24 seals the opening of the stirring pot 3. With this arrangement, the cover plate 24 can prevent the slurry in the stirring pot 3 from splashing out during stirring, thereby ensuring the accuracy of the experimental results. In addition, during the stirring process, the cover plate 24 and the support seat 12 can respectively limit the position of the stirring pot 3 from the upper and lower positions of the stirring pot 3, further enhancing the fixing effect of the stirring pot 3 and making the stirring pot 3 more stable. At the same time, the arrangement of the cover plate 24 can make the stress of the stirring blades 23 on the stirring pot 3 be evenly transmitted to the limiting column 32, which also has a certain protective effect on the limiting column 32.

[0037] Furthermore, the adjusting member includes a protruding plate 31 fixed along the outer wall of the stirring pot 3, the lower end of the protruding plate 31 is connected to the limiting column 32, a guide groove is vertically opened at the upper end of the protruding plate 31, an adjusting pin 311 is dynamically sealed in the guide groove, and a first spring 312 is arranged in the guide groove to maintain the relative position of the adjusting pin 311 and the protruding plate 31, the first spring 312 limits the upper end of the adjusting pin 311 from extending out of the upper end of the protruding plate 31, the plug-in block 321 is dynamically sealedly connected to the cavity at the corresponding position on the limiting column 32, an airway 313 with one end connected to the guide groove is opened in the protruding plate 31, and the other end of the airway 313 is connected to the cavity where the plug-in block 321 is located, which is located on one side of the middle part of the limiting column 32.

[0038] When the stirring pot 3 is moved to the stirring height, the cover plate 24 can press the adjusting pin 311 down to the inside of the protruding plate 31, so as to adjust the position of the adjusting pin 311 by utilizing the distance change between the stirring pot 3 and the cover plate 24, thereby realizing the position adjustment of the plug-in block 321. Optionally, the adjusting pin 311 is fixedly connected to the first spring 312, and the adjusting pin 311 is restricted by the first spring 312 and cannot be completely moved out of the guide groove. When the stirring pot 3 is moved to the stirring height, the stirring pot 3 drives the adjusting pin 311 to move upward synchronously. During this process, the adjusting pin 311 is restricted by the first spring 312 and extends outward from the protruding plate 31. When the stirring pot 3 is moved upward to the stirring height, the adjusting pin 311 is restricted by the first spring 312 and extends outward from the protruding plate 31. When the stirring pot 3 is moved upward to the stirring height, the adjusting pin 311 is When the cam 312 is in the closed position, the first spring 312 is in the closed position, and the air in the cam 312 is pushed into the air passage 313 ...

[0039] Furthermore, a second spring 322 is disposed in the limiting column 32 to maintain the relative position of the plug-in block 321 and the limiting column 32 , and the second spring 322 limits the plug-in block 321 to be in the limiting column 32 .

[0040] Specifically, the difference between the air pressure in the guide groove and the airway 313 and the external air pressure is utilized to achieve the poor stability of the cancellation of the cooperation between the plug-in block 321 and the plug-in slot 122. By arranging the second spring 322 in the limiting column 32, when the distance between the stirring pot 3 and the cover plate 24 increases, the first spring 312 pushes the adjusting pin 311 to reset, and the second spring 322 can pull the plug-in block 321 into the cavity on the limiting column 32, thereby canceling the cooperation between the plug-in block 321 and the plug-in slot 122.

[0041] In another embodiment of the utility model, at least three groups of plug-in blocks 321 are provided, and the limit blocks are distributed along the circumference of the limit column 32, the plug-in grooves 122 are provided corresponding to each plug-in block 321, an annular cavity 324 is opened in the limit column 32, the other end of the airway 313 is connected to the annular cavity 324, and the annular cavity 324 is connected to the cavity where each plug-in block 321 is located on the limit column 32 through the connecting hole 323.

[0042] Specifically, this embodiment limits the limit column 32 from multiple angles by setting the number of plug-in blocks 321 to be greater than or equal to three groups, and distributes the three groups of plug-in blocks 321 along the axial direction of the limit column 32, thereby further improving the fixing effect of the limit column 32 on the support seat 12.

[0043] Furthermore, the diameter of the communication hole 323 is smaller than the diameter of the air passage 313 .

[0044] Specifically, by setting the diameter of the connecting hole 323 to be smaller than the diameter of the airway 313, less gas is needed to push the plug-in block 321 while satisfying the position adjustment of the plug-in block 321. When the number of the plug-in blocks 321 increases, there is no need to change the stroke of the adjustment pin 311 in the guide groove, and the adjustment requirements of the plug-in block 321 can also be met.

[0045] Furthermore, the insertion groove 122 is an annular groove.

[0046] Specifically, when the plug-in groove 122 is set to be ring-shaped, when the stirring pot 3 is placed on the support base 12 at any angle, the plug-in block 321 can cooperate with the plug-in groove 122, and there is no need to ensure that the stirring pot 3 is at a specific angle, so that the stirring pot 3 can be fixed through the cooperation of the plug-in block 321 and the plug-in groove 122.

[0047] Furthermore, the lower part of the stirring pot 3 is hemispherical.

[0048] Specifically, the bottom of the existing mixing pot 3 protrudes upward, so it is not convenient to completely scrape out the mixed slurry, and it is not convenient to clean the mixing pot 3. Now the lower part of the mixing pot 3 is set to be hemispherical. After the cement and water are mixed, the slurry in the mixing pot 3 can be completely scraped out by a semicircular scraper, and the mixing pot 3 is easy to clean.

[0049] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
