Description

Technical Field

[0001] This utility model belongs to the field of cement mixing testing, and relates to a cement mixer blade and pot wall gap testing mechanism and testing equipment. Background Technology

[0002] For example, Chinese patent literature discloses a cylindrical feeler gauge for calibrating the gap between the impeller blades of a cement mixer [202320503437.1], which includes a handheld part and a first detection part and a second detection part fixed at both ends of the handheld part. The first detection part includes a first connecting rod and a first hook-shaped ruler fixed at the end of the first connecting rod. The second detection part includes a second connecting rod and a second hook-shaped ruler fixed at the end of the second connecting rod. Both the first hook-shaped ruler and the second hook-shaped ruler define a groove for accommodating the outer edge of the mixing blade. The opening of the groove is inclined relative to the handheld part. The first hook-shaped ruler has a first measuring gap section opposite to its opening, and the second hook-shaped ruler has a second measuring gap section opposite to its opening. The minimum value of the impeller gap range is d, the maximum value is D, the outer diameter of the first measuring gap section is d, and the outer diameter of the second measuring gap section is D.

[0003] The drawback of the above technical solution is that the method of using a handheld feeler gauge for calibration and testing is prone to errors, which reduces the accuracy of the test. Moreover, the feeler gauge cannot simultaneously calibrate and test the gap between the pot wall and the bottom of the pot. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a cement mixer blade and pot wall gap detection mechanism and equipment.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] The cement mixer blade-pot wall gap detection mechanism includes:

[0007] A mixer includes a mixing pot, mixing blades with one end extending into the mixing pot, and positioning protrusions spaced apart on the upper edge of the mixing pot;

[0008] A positioning ring is provided at the upper end of the mixing pot. The positioning ring includes a positioning groove that fits onto the positioning protrusion, and an arc-shaped channel located inside the mixing pot is provided on the positioning ring.

[0009] The gap detection rod includes a handle disposed in the arc-shaped channel, a vertical detection section passing through the inner wall of the mixing pot and the stirring blade, and a transverse detection section disposed at the end of the vertical detection section away from the handle and passing through the bottom wall of the mixing pot and the stirring blade.

[0010] Furthermore, the positioning ring has a C-shaped structure and is provided with a clearance notch for the stirring blades to pass laterally.

[0011] Furthermore, the positioning ring has a ring structure.

[0012] Furthermore, the positioning ring is provided with radially arranged reinforcing ribs.

[0013] Furthermore, the outer edge of the positioning ring is arranged circumferentially along the inner wall edge of the mixing pot.

[0014] Furthermore, the handle is provided with a step that overlaps the arc-shaped channel.

[0015] Furthermore, the horizontal cross-section of the transverse detection section has a U-shaped structure.

[0016] Furthermore, the handle is provided with a radial indicator that extends radially on the same side as the lateral detection section.

[0017] This utility model also provides a testing device having a cement mixer blade and pot wall gap testing mechanism as described above.

[0018] Compared with existing technologies, this cement mixer blade-pot wall gap detection mechanism uses a positioning ring fitted onto the upper end of the mixing pot as the reference for the standard detection path of the gap detection rod. This makes the handheld gap detection rod operation more standardized and accurate, improving detection precision. Moreover, the gap detection rod can simultaneously detect the gap between the pot wall, the bottom of the pot, and the mixing blades, improving detection efficiency. Attached Figure Description

Detailed Implementation

[0024] Example 1, please refer to Figures 1 to 4 This is a schematic diagram of a cement mixer blade-pot wall gap detection mechanism and detection equipment provided by this utility model. The cement mixer blade-pot wall gap detection mechanism includes: a mixer 10, a positioning ring 20 disposed on the mixer 10, and a gap detection rod 30 disposed on the positioning ring 20. It can be imagined that this cement mixer blade-pot wall gap detection mechanism also includes other functional components and specific structures, such as electrical connection components, installation structures, etc., which are all technologies known to those skilled in the art, and therefore will not be described in detail here.

[0025] In this embodiment, the mixer 10 is used for mixing cement mortar or cement paste. It includes a mixing pot 11. The bottom of the mixing pot 11 is detachably connected to the working platform of the mixer 10, which facilitates loading and unloading before and after mixing. The inner cavity of the mixing pot 11 is usually a cylindrical structure that is wider at the top and narrower at the bottom, which is conducive to mixing.

[0026] The mixer 10 is equipped with a drive motor, and at the output end of the drive motor is a stirring blade 12 that can extend into the mixing pot 11. The stirring blade 12 is generally eccentrically arranged, that is, there is a minimum gap between the stirring blade 12 and the mixing pot 11. The upper end of the mixing pot 11 has a thickness, and positioning protrusions 13 are provided at intervals on the upper edge of the mixing pot 11. The positioning protrusions 13 are used for positioning the positioning ring 20.

[0027] In this embodiment, the positioning ring 20 is disposed at the upper end of the mixing pot 11. The positioning ring 20 includes a positioning groove 21 sleeved on the positioning protrusion 13, which cooperates with the positioning protrusion 13 to form the positioning of the positioning ring 20 at the upper end of the mixing pot 11, preventing lateral displacement or circumferential rotation. The positioning ring 20 is provided with an arc-shaped channel 22 located inside the mixing pot 11. The arc-shaped channel 22 is an arc-shaped strip hole structure, which is used for positioning insertion for gap detection function.

[0028] In this embodiment, the positioning ring 20 has a C-shaped structure and a clearance notch 23 for the stirring blade 12 to pass laterally. The structure of the clearance notch 23 allows the positioning ring 20 to be removed and placed without raising or lowering the stirring blade 12, making the installation and removal of the positioning ring 20 more convenient and quick. The positioning ring 20 overlaps the stirring pot 11, with its outer edge circumferentially arranged along the inner wall edge of the stirring pot 11. Combined with the positioning groove 21 extending circumferentially outward from the positioning ring 20, the positioning ring 20 is installed stably and reliably, facilitating the insertion and engagement of the gap detection rod 30. Optimally, the positioning ring 20 is provided with radially arranged reinforcing ribs 24, which enhance the structural strength of the positioning ring 20 and prevent deformation after collision.

[0029] In other embodiments, the positioning ring 20 has a ring structure, which is highly versatile and reduces the need for circumferential adjustment of the positioning ring 20.

[0030] In this embodiment, the gap detection rod 30 includes a handle 31 disposed in the arc-shaped channel 22. The handle 31 is the larger diameter end, and a step 34 is provided on the handle 31 to overlap the arc-shaped channel 22, which limits the extension length of the gap detection rod 30 and prevents the gap detection rod 30 from falling into the mixing pot 11.

[0031] A vertical detection section 32 is provided between the inner wall of the mixing pot 11 and the stirring blade 12. The shape of the vertical detection section 32 is set along the inner wall of the mixing pot 11. Initially, the vertical detection section is inserted in an empty position, and then inserted at the narrowest position in the horizontal direction close to the inner wall of the mixing pot 11 and the stirring blade 12 to avoid the problem of initial insertion interference.

[0032] A transverse detection section 33 is provided at the end of the vertical detection section 32 away from the handle 31, passing between the bottom wall of the mixing pot 11 and the stirring blade 12. The transverse detection section 33 is used to simultaneously detect the gap between the bottom wall of the mixing pot 11 and the stirring blade 12. Optimally, the horizontal cross section of the transverse detection section 33 has a U-shaped structure to enhance the structural strength of the transverse detection section 33 and prevent deformation during rotation.

[0033] The handle 31 is provided with a radial indicator 35 extending radially on the same side as the transverse detection section 33. The radial indicator 35 is used to display the direction of the transverse detection section 33 that is immersed in cement mortar, so as to avoid the problem of collision caused by the automatic rotation of the gap detection rod 30.

[0034] It should be noted that the actual gap between the pot walls and the outer diameter of the gap detection rod 30 are relatively small. In the attached diagram, to better illustrate the structure, the dimensions of the pot wall gap and the gap detection rod 30 have been enlarged. Specifically, when the standard gap between the pot wall of the mixing pot 11 and the mixing blade 12 is 3mm ± 1mm, it can be calibrated and tested using vertical detection sections with outer diameters of 2mm and 4mm respectively. The gap at the bottom of the pot and the transverse detection section 33 are set in the same way.

[0035] The positioning ring 20 is sleeved on the upper end of the mixing pot 11 as the reference for the standard detection path of the gap detection rod 30, which makes the handheld detection operation of the gap detection rod 30 more standardized and accurate, and improves the detection accuracy. Moreover, the gap detection rod 30 can simultaneously detect the gap between the pot wall, the pot bottom and the stirring blade 12, thus improving the detection efficiency.

[0036] Example 2: This utility model also provides a detection device, which has a cement mixer blade and pot wall gap detection mechanism as described above. Except for the cement mixer blade and pot wall gap detection mechanism, the other components are all existing technology or commercially available parts.

[0037] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
