[0002] In the tensile bond strength test of plastering mortar, the forming process plays a crucial role in the accuracy of the test results. The forming process usually requires the use of various tools such as trowels and spatulas, and necessitates the frequent replacement of these tools.

[0003] The existing molding process relies on manual vibration and compaction, which is cumbersome and prone to causing the molding frame to shift, resulting in slurry overflow. At the same time, the existing technology lacks efficient smoothing tools after slurry filling, requiring multiple back-and-forth scraping, which can easily lead to inconsistent surface flatness. This is not only inefficient, but also prone to uneven slurry distribution and inconsistent density within the molding frame, thus affecting the reliability of the test results. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a material shovel structure for tensile bond strength testing of plastering mortar. The structure is compact, simple to operate, and easy to use and maintain. It can integrate the three functions of material picking, vibration feeding and vibration smoothing into one, solving the problems of cumbersome operation, frequent tool replacement, uneven mortar distribution and inconsistent surface flatness in the prior art, thereby improving the test efficiency and the reliability of the test results.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A material shovel structure for a tensile bond strength test of plastering mortar mainly includes: a shovel body 1 and a shovel handle 2. The shovel handle 2 is fixedly sleeved at the rear end of the shovel body 1. A feeding plate 6 is fixedly connected to the front end of the shovel body 1.

The rear end of the shovel handle 2 is hollow and is equipped with a battery compartment 10. The micro vibrator 8 and the micro vibrator 9 are electrically connected to the battery pack in the battery compartment 10 through power supply wires.

[0025] Furthermore, an adjusting bolt 13 is provided at the hinge of the smearing plate 7 and the slider 3 to adjust the rotation angle of the smearing plate 7 relative to the shovel body 1.

[0026] Furthermore, the outer surface of the shovel handle 2 is provided with anti-slip texture.

[0027] Furthermore, a switch 11 and a power indicator light 12 are connected in series on the power supply wire, and both the switch 11 and the power indicator light 12 are fixedly installed on the side of the shovel body 1.

[0028] Furthermore, the shovel body 1, the feeding plate 6, and the smearing plate 7 are all provided with wire grooves inside.

[0029] Example 2: This example provides a material shovel structure for a tensile bond strength test of plastering mortar. The material shovel is made of stainless steel or aluminum alloy to ensure its strength and corrosion resistance.

[0030] Furthermore, the surfaces of both the feeding plate and the slurry plate are polished to reduce friction with the slurry.

[0031] Furthermore, the width of the feeding plate is 35-38mm to ensure smooth feeding.

[0032] Furthermore, the width of the smearing plate is 45-70mm to ensure that the smearing can cover the entire forming area.

[0039] In practical use: 1) Grind a 70×70×20mm (length×width×thickness) cement mortar base test block or a 70×70×40mm (length×width×thickness) concrete base test block. Then, evenly apply a release agent to the inside of a molding frame with an outer frame size of 70×70mm (length×width) and an inner frame size of 40×40mm (length×width). Place the molding frame on the ground base test block for later use. 2) Before conducting the tensile bond strength molding test of plaster mortar, first check whether the battery in the shovel battery compartment has sufficient power and whether the switch and power indicator light are working properly; adjust the position of the limit hole where the slider is located and rotate the trowel plate so that the angle between the trowel plate and the molding frame is about 45° when adding material. 3) Mix the slurry according to the specified mixing ratio and mixing system, then immerse the feeding plate of the shovel into the slurry to perform the material collection operation; 4) Hold the molding frame and place the shovel after taking the material into the 40×40mm molding frame, so that the bottom of the feeding plate contacts the surface of the base test block in the molding frame. Fine-tune the angle between the slurry plate and the molding frame by using the slider and adjusting bolts to ensure that the angle is about 45°. Then press the switch to start the micro vibrator at the end of the feeding plate and the slurry plate, so that the slurry is evenly filled into the molding frame under the combined action of gravity and vibration. When the bottom of the slurry plate contacts the surface of the slurry, slowly move the shovel to ensure that the slurry is filled into all corners of the molding frame, and at the same time, make the slurry plate cover the entire molding area at one time to ensure the flatness and density of the slurry surface. 5) After the slurry plate has smoothed the 40×40mm inner frame at an angle of about 45°, press the switch again to stop the micro vibrator at the end of the feeding plate and the slurry plate; after smoothing to the 70×70mm outer frame, collect the excess slurry to complete the molding operation of one tensile bond strength specimen.
