[0002] At present, mortar is used in many aspects such as construction and bridges. A mortar consistency meter is an instrument for measuring the fluidity of mortar and is widely used in the engineering industry.

[0003] The utility model patent with the publication number of CN211402040U discloses a mortar consistency meter, which includes a base. A test cylinder is arranged on the base. The base is provided with a sliding rod. One end of the sliding rod is fixedly connected to the base, and the sliding rod is perpendicular to the base. A placing rod is slidably connected to the circumferential side wall of the sliding rod. One end of the placing rod is sleeved on the sliding rod, and the other end of the placing rod is detachably and fixedly connected with a conical test body. The placing rod is perpendicular to the sliding rod. The test body is located above the test cylinder and the tip of the test body faces the top end of the test cylinder. A knocking component is connected to the base. The knocking component includes a knocking seat. The knocking seat is fixedly connected with a knocking driving part with a telescopic rod. The end of the telescopic rod facing the test cylinder is fixedly connected with a knocking plate. The knocking driving part drives the knocking plate to continuously knock against the outer wall of the test cylinder through the telescopic rod.

[0004] When the mortar consistency meter knocks the outer wall of the test cylinder through the knocking plate, multiple knocking plates need equal driving cylinders to drive, so that the equipment quantity of the consistency meter is large and it is inconvenient to use. Summary of the Utility Model

[0005] In order to reduce the equipment quantity of the mortar consistency meter, this application provides a mortar consistency meter.

[0006] The mortar consistency meter provided by this application adopts the following technical scheme:

[0007] A mortar consistency meter includes a base. A vertically upward test cylinder and a sliding rod are arranged on the base. A horizontal placing rod is slidably connected to the sliding rod in the vertical direction. The end of the placing rod far away from the sliding rod is detachably connected with a test cone. A plurality of knocking plates are slidably connected to the base. The plurality of knocking plates are arranged along the circumference of the test cylinder and are all slidably connected to the base in the radial direction of the test cylinder. A driving part for driving the plurality of knocking plates to move and knock the outer wall of the test cylinder is arranged on the base.

[0008] By adopting the above technical solution, the operator first places the mortar to be measured into the test cylinder, and the driving member drives the knocking plate to continuously knock on the outer wall of the test cylinder, causing the test cylinder to vibrate; under the vibration effect of the knocking cylinder inside the test cylinder, the top surface of the mortar gradually becomes flat, and then the test cone falls into the mortar through free-fall motion. After the test body sinks into the mortar, the viscosity of the mortar is obtained. Driving a plurality of knocking plates to knock on the test cylinder by one driving member plays a role in reducing the equipment.

[0009] Optionally, the driving member includes a driving cylinder, a plurality of sliding blocks and a plurality of connecting rods. The driving cylinder is arranged directly below the test cylinder and is vertically upward. A plurality of the sliding blocks are all slidably connected to the base along the radial direction of the test cylinder. A plurality of the knocking plates are respectively connected to the plurality of sliding blocks. One ends of the plurality of connecting rods are rotatably connected to the upper end of the piston rod of the driving cylinder, and the other ends of the plurality of connecting rods are respectively rotatably connected to the plurality of sliding blocks.

[0010] By adopting the above technical solution, the driving cylinder drives the plurality of connecting rods to move up and down. When the plurality of connecting rods move up and down, they drive the sliding blocks to move in the horizontal direction. When the sliding blocks move, they drive the knocking plates to move. This structure enables one cylinder to drive a plurality of knocking plates to move, playing a role in reducing the equipment.

[0011] Optionally, a support plate is sleeved outside the test cylinder. A plurality of sliding grooves are arranged on the support plate along the radial direction of the test cylinder. A plurality of the sliding blocks are respectively slidably connected in the plurality of sliding grooves.

[0012] By adopting the above technical solution, the sliding grooves on the support plate play a role in accommodating the sliding blocks, reducing the deviation of the sliding blocks during movement.

[0013] Optionally, limiting strips are arranged on the inner side walls of the sliding grooves, and limiting grooves for engaging with the limiting strips are formed on the side walls of the sliding blocks.

[0014] By adopting the above technical solution, the engagement of the limiting strips and the limiting grooves plays a role in reducing the situation of the sliding blocks sliding out of the sliding grooves.

[0015] Optionally, a plurality of limiting blocks are arranged on the support plate. The plurality of limiting blocks are respectively located at one ends of the plurality of sliding grooves away from the test cylinder. The limiting blocks are connected to the support plate by bolts.

[0016] By adopting the above technical solution, the limiting blocks play a role in closing one end of the sliding grooves, reducing the situation of the sliding blocks sliding out of the sliding grooves.

[0017] Optionally, a plurality of impact blocks made of rubber are fixedly connected to the side surface of the knocking plate facing the test cylinder.

[0018] By adopting the above technical solution, a number of impact blocks are provided, which can converge the force exerted by the knocking plate on the outer wall of the test cylinder, improve the intensity of the knocking force received by the outer wall of the test cylinder, accelerate the speed at which the top surface of the mortar inside the test cylinder resumes flatness, and improve the working efficiency of the knocking plate.

[0019] Optionally, the impact block is arranged in a hemispherical shape.

[0020] By adopting the above technical solution, the hemispherical impact block is in a point-contact form when contacting the outside of the test cylinder, so that the vibration of the knocking plate on the outer wall of the test cylinder can be further converged, further improving the intensity of the knocking force received by the test cylinder and the use effect of the knocking plate.

[0021] Optionally, four knocking plates are provided, and the four knocking plates are arranged in a square matrix with the test cylinder as the center.

[0022] By adopting the above technical solution, during the testing process, the four knocking plates are all in contact with the outside of the test cylinder, so that the outer wall of the knocking cylinder can be restricted by the knocking plates during use, preventing the test cylinder from tipping over during use and improving the use stability of the test cylinder.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The driving cylinder drives the plurality of connecting rods to move up and down. When the plurality of connecting rods move up and down, they drive the sliding block to move horizontally. When the sliding block moves, it drives the knocking plate to move. This structure enables one cylinder to drive multiple knocking plates to move, playing a role in reducing equipment.

[0025] 2. The limiting strip and the limiting groove are engaged to prevent the sliding block from sliding out of the sliding groove.

[0026] 3. The four knocking plates are all in contact with the outside of the test cylinder, so that the outer wall of the knocking cylinder can be restricted by the knocking plates during use, preventing the test cylinder from tipping over during use and improving the use stability of the test cylinder.

Detailed implementation manners

[0034] The following further elaborates on the present application in conjunction with the attached Figure 1-6 drawings.

[0035] An embodiment of the present application discloses a mortar consistency meter. Referring to Figure 1 , a mortar consistency meter includes a horizontal base 1, on which a vertically upward sliding rod 12 and a test cylinder 11 are fixed. A horizontal placing rod 13 is slidably connected to the sliding rod 12 in the vertical direction. One end of the placing rod 13 away from the sliding rod 12 is detachably connected with a test cone 14. The test cone 14 is located directly above the test cylinder 11. When the test cylinder 11 is filled with mortar, the test cone 14 falls into the test cylinder 11 to test the viscosity of the mortar.

[0036] Referring to Figure 1 , Figure 2 and Figure 3 , a horizontal support plate 3 is sleeved outside the test cylinder 11. Four horizontal sliding grooves 31 are formed on the support plate 3. The four sliding grooves 31 are distributed along the circumferential direction of the test cylinder 11 and are all arranged along the radial direction of the test cylinder 11. A knocking plate 4 is slidably connected in each of the four sliding grooves 31 in a direction close to or away from the test cylinder 11. The surface of the knocking plate 4 facing the test cylinder 11 is an arc-shaped surface that fits the outer ring surface of the test cylinder 11. A plurality of impact blocks 41 are fixedly connected to the surface of the knocking plate 4 facing the test cylinder 11. The impact blocks 41 are hemispherical. When the hemispherical impact blocks 41 contact the outside of the test cylinder 11, it is a point contact form, so that the vibration of the knocking plate 4 on the outer wall of the test cylinder 11 can be further concentrated, further improving the intensity of the knocking force received by the test cylinder 11 and enhancing the use effect of the knocking plate 4.

[0037] Referring to Figure 1 , Figure 4 andFigure 5 On the base 1, a driving member 2 for driving the moving of the knocking plate 4 is installed. The driving member 2 includes a driving cylinder 21, four sliding blocks 22 and four connecting rods 23. The four sliding blocks 22 are respectively fixedly connected to the four knocking plates 4. The four sliding blocks 22 are respectively slidably connected in four sliding grooves 31. On the inner side wall of the sliding groove 31, a limiting strip 311 is fixed. On the side wall of the sliding block 22, a limiting groove 221 for engaging with the limiting strip 311 is formed. The engagement between the limiting strip 311 and the limiting groove 221 serves to prevent the sliding block 22 from slipping out. The driving cylinder 21 is arranged directly below the test cylinder 11. The four connecting rods 23 are all rotatably connected to the piston rod of the driving cylinder 21. The ends of the four connecting rods 23 far from the driving cylinder 21 are respectively rotatably connected to the four sliding blocks 22. When the piston rod of the driving cylinder 21 moves up and down, the sliding block 22 is driven to move horizontally through the transmission of the connecting rod 23, thereby driving the knocking plate 4 to strike the test cylinder 11.

[0038] Refer to Figure 5 and Figure 6 On the support plate 3, four limiting blocks 33 are installed. The four limiting blocks 33 are respectively located at one ends of the four sliding grooves 31 far from the test cylinder 11. The limiting blocks 33 are connected to the support plate 3 by bolts 331.

[0039] The implementation principle of a mortar consistency meter in an embodiment of the present application is as follows: After an operator injects mortar into the test cylinder 11, the driving cylinder 21 is started. When the piston rod of the driving cylinder 21 moves up and down, it drives the connecting rod 23 to move up and down. When the connecting rod 23 moves up and down, it drives the corresponding sliding block 22 to approach or move away from the test cylinder 11 along the direction of the sliding groove 31. When the sliding block 22 moves, it drives the knocking plate 4 to strike the outer wall of the test cylinder 11, so that the mortar in the test cylinder 11 is more uniform. This structure drives the movement of multiple knocking plates 4 by one driving cylinder 21, reducing the number of devices.

[0040] The above are all the preferred embodiments of the present application. It does not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
