Description

Technical Field

[0001] The invention relates to the technical field of mortar consistency density measurement, in particular to an electronic digital display type mortar consistency density measuring instrument. Background Art

[0002] Appropriate consistency makes it easier to spread and fill the mortar during the construction process, thereby ensuring the flatness and bonding strength of the wall surface. Therefore, mortar that is too thick or too thin will affect the construction effect and quality. When making mortar, an electronic digital mortar consistency density meter is needed to measure the mortar consistency density.

[0003] The patent name disclosed in the prior art with the announcement number "CN109813632A" is "A Mortar Consistency Density Meter", which discloses that first, the surface of the mortar cup and the cone rod should be wiped clean, the cone rod should be lightly rubbed with a small amount of lubricating oil, and the excess oil should be wiped off so that the cone rod can slide freely in the vertical direction, and then the support frame should be adjusted to a suitable position height and fixed with an adjusting bolt. First, the mass reading of the empty mortar cup on the weight scale should be recorded, and then the mortar should be loaded into the mortar cup at the highest limit line, and the mass reading on the weight scale at this time should be recorded. The standard test cone is driven by the cone rod to descend into the mortar until it stops. When the digital display cannot be used, the descending distance of the standard test cone can be directly read from the scale on the standard test cone, and the consistency of the mortar can be obtained. After the test is completed, the density of the mortar can be obtained by calculating the volume ratio of the mass of the mortar to the fixed value. , and the scale indication on the standard test cone is the consistency of the mortar, and the patent name disclosed in the prior art with the announcement number "CN214749578U" is "A Mortar Consistency Meter", which discloses that the base is first adjusted through the leveling assembly, and the leveling bolt is rotated during adjustment to drive the base to rise and fall, and the scale of the spirit level is observed during the adjustment process. When the spirit level indicates horizontal, the leveling process is completed, and then the mortar sample is placed in the slurry barrel and allowed to stand. At this time, the first driving ring is rotated, and the first driving ring drives the test assembly to rise and fall, so that the tip of the test cone just contacts the mortar surface, and then the first fixing piece is rotated to press the first connecting sleeve and the column tightly, and then the scale is slid to make the display read zero, and then the second driving ring is rotated, and the second driving ring drives the measuring assembly to rise and fall, so that the bottom wall of the scale contacts the top wall of the test rod, and then the second fixing piece is rotated to press the second connecting sleeve and the column tightly to start the test.

[0004] The mortar consistency density meter in the above-mentioned prior art, when in use, directly places the mortar tube containing the mortar sample on the base, and then performs the measurement. If the mortar surface in the mortar tube is not flat, the cone will be subjected to uneven resistance when sinking, which will lead to inaccurate measurement results, making the mortar consistency density meter unable to perform the measurement work well.

The second connecting column 16 is reciprocatingly moved left and right through the movable frame 22. A central auxiliary positioning member 131 is fixed at the bottom of the shaking frame 13. The central auxiliary positioning member 131 is funnel-shaped.

[0045] First, place the empty container 3 on the weighing sensor 2. The mass measured at this time is M1. Then pour a certain amount of mortar into the container 3. The total mass measured at this time is M2. It can be seen that the mass of the mortar is M=M2-M1. Then put the container 3 filled with mortar into water. At this time, the pressure sensor in the container 3 measures the buoyancy F of the container 3 in the water. Later, according to the Archimedes principle, the volume of the mortar can be calculated, and then the density of the mortar can be obtained. The density value is displayed on the display screen of the electronic digital display 8. This part is existing technology and will not be introduced in detail here. Then, the container 3 filled with mortar is placed in the water. After the container 3 is placed on the weighing sensor 2, the automatic reset component 11 of the electric push rod is started, and the output end of the automatic reset component 11 drops to the lowest position. At this time, the output end of the automatic reset component 11 is separated from the extension plate 91, and then the motor in the base body 1 is started. The motor drives the threaded rod 4 to rotate. When the threaded rod 4 rotates, it drives the lifting control block 6 connected to the outer thread to move downward. At this time, the left side of the lifting control block 6 moves downward on the outside of the limit vertical rod 5, thereby ensuring that the lifting control block 6 stably drives the support frame 7 and the electronic digital display 8 to move downward, and the electronic digital display 8 drives the support rod 9 and the cone 10 to move downward.

[0046] At the same time, the support frame 7 drives the shaking frame 13 and the center auxiliary positioning member 131 to move downward together through the second connecting column 16 and the first connecting column 15. At this time, the center auxiliary positioning member 131 with a funnel-shaped structure first contacts the top of the container 3. If the container 3 is not placed in the center of the weighing sensor 2, the center auxiliary positioning member 131 that continues to descend will apply a thrust to the container 3, which is convenient for correcting the position of the container 3. The center of the container 3 is in the same vertical line as the center of the weighing sensor 2 and the center of the cone 10. At the same time, the shaking frame 13 descends to the inner wall and contacts the outer wall above the container 3. At this time, the front side of the support frame 7 The transmission gear 18 in the surface is meshed and connected with the rack assembly 17, so that the transmission gear 18 drives the single-rotation reciprocating screw 19 to rotate. At this time, when the single-rotation reciprocating screw 19 rotates, it drives the movable frame 22 to move back and forth left and right. Then the movable frame 22 drives the upper end of the second connecting column 16 to move back and forth left and right on the outside of the second slide bar 161. The lower end of the second connecting column 16 drives the shaking frame 13 to move back and forth left and right through the first connecting column 15, so that the shaking frame 13 can drive the container 3 to shake back and forth left and right on the weighing sensor 2. The ball installed on the bottom surface of the container 3 can reduce the friction between the upper surface of the weighing sensor 2, which is convenient for driving the container 3 to shake well.

[0047] At the same time, when the rocking frame 13 moves to the right, the fixed limit self-pushing column 14 will apply a resistance to the right side of the center auxiliary positioning member 131 below the rocking frame 13. Since the limit self-pushing column 14 is set on the right side of the center auxiliary positioning member 131 and is located at the rear side of the transverse center line of the center auxiliary positioning member 131, the limit self-pushing column 14 will apply a forward thrust to the center auxiliary positioning member 131 that continues to move to the right, thereby causing the center auxiliary positioning member 131 and the rocking frame 13 to drive the filling container 3 to move back and forth. At this time, the first sliding bar 152 slides back and forth inside the lower end of the second connecting column 16, and cooperates with the storage force of the return spring 153 to ensure that the rocking frame 13 and the center auxiliary positioning member 131 slide stably back and forth. Therefore, by rocking the filling container 3 left and right and back and forth, it is convenient to quickly make the mortar surface in the filling container 3 flat, so that the resistance encountered by the cone 10 when it sinks and inserts into the mortar is uniform, which is convenient to improve the accuracy of the later measurement data.

[0048] When the cone 10 drops to the bottom and just contacts the upper surface of the mortar in the container 3, the motor stops working. At this time, the lifting control block 6 and the support frame 7 are fixed, and the latch rod 81 is manually pulled backward so that the front end of the latch rod 81 is separated from the plug hole 93 on the rear side of the support rod 9. Then, the support rod 9 and the cone 10 fall freely downward, and then the cone 10 sinks and is inserted into the mortar in the container 3. When the cone 10 is stationary in the container 3, the displacement sensor in the electronic digital display 8 detects the sinking depth of the cone 10, converts the displacement into an electrical signal, and transmits it to the electronic control module in the electronic digital display 8. The electronic control module processes and analyzes the electrical signal, converts the displacement into a corresponding sinking value, and displays it on the display screen on the electronic digital display 8, so that the mortar consistency value can be directly read. This part is existing technology and will not be introduced in detail here.

[0049] Example 2: The electronic digital display mortar consistency density tester in this embodiment has a specific structure. Figure 1 、 Figure 8 As shown, on the basis of embodiment 1, a horizontally arranged extension plate 91 is installed on the left side of the upper end of the support rod 9, and an automatic reset component 11 for driving the cone 10 to automatically rise and reset is installed above the support frame 7. A third slide bar 20 is installed in a groove on the upper surface of the support frame 7. The outer side of the third slide bar 20 passes through the bottom end of the automatic reset component 11, and the right end of the third slide bar 20 is nested and connected to the outer side. The output end of the automatic reset component 11 is inserted into the groove opened on the bottom surface of the extension plate 91. The automatic reset component 11 is an electric push rod, and a vertical plate 12 is fixed to the upper surface of the support frame 7. The vertical plate 12 is arranged on the left side of the automatic reset component 11, and a row of self-pushing balls 121 are installed on one side of the vertical plate 12 close to the automatic reset component 11. A control ball 111 is fixed on the left side above the output end of the automatic reset component 11, and a self-pushing ball 121 is arranged above the control ball 111. The control ball 111 push rod and the self-pushing ball 121 drive the automatic reset component 11 to slide back and forth left and right.

[0050] When use is finished and the height position of the cone 10 needs to be reset, the automatic reset component 11 is started. The automatic reset component 11 is an electric push rod. At this time, the output end of the automatic reset component 11 moves upward. When the output end of the automatic reset component 11 moves to contact the extension plate 91 and is inserted into the groove in the bottom surface of the extension plate 91, the output end of the automatic reset component 11 continues to drive the extension plate 91 and the support rod 9 to rise, and the support rod 9 drives the cone 10 to move upward. When the cone 10 moves to a fixed position, the use of the automatic reset component 11 is stopped, and then the pin rod 81 is inserted into the socket hole 93, so as to fix the cone 10 well and reset the cone 10 well.

[0051] When the control ball 111 is separated from the row of self-pushing balls 121, the automatic reset component 11, the support rod 9 and the cone 10 are automatically driven to move to the left and reset by the stored force of the connecting spring 21, and so on, so that the cone 10 can be shaken left and right to a certain extent, so that the mortar adhered to the surface of the cone 10 can be shaken and dropped into the filling container 3 for collection, which is convenient for cleaning the cone 10 later.

[0052] Example 3: The electronic digital display mortar consistency density meter in this embodiment can further shake off the mortar adhered to the surface of the cone 10. For the specific structure, refer to the attached Figure 9 As shown, on the basis of Example 2, a micro-vibration motor 112 is installed on the output end of the automatic reset component 11, and an extension plate 91 is provided above the micro-vibration motor 112. A through hole 92 is opened inside the extension plate 91, and a pushing column 113 is fixed on the output end of the automatic reset component 11. The pushing column 113 is inserted into the through hole 92, and the highest point of the pushing column 113 is higher than the highest point of the micro-vibration motor 112. When the automatic reset component 11 drives the extension plate 91 to move upward, the micro-vibration motor 112 above the output end of the automatic reset component 11 will drive the extension plate 91 to move up and down reciprocatingly, and at the same time, the pushing column 113 is inserted into the through hole 92, so that the automatic reset component 11 drives the extension plate 91 to move back and forth left and right. Therefore, by the same token, the cone 10 can be shaken back and forth left and right while being shaken up and down. Therefore, the mortar adhered to the surface of the cone 10 can be further shaken off, which is convenient for reducing the workload of cleaning the surface of the cone 10 in the later stage.
