[0009] Preferably, the diamond-shaped sheet consists of four rods, which are hinged together by torsion spring rods.

[0010] A method for using an adjustable cement mortar vibrating table comprises the following steps: S1. First, place the mortar specimen on the surface of the bottom plate, and then manually rotate the cover plate, insert the cylinders on both sides of the two cover plates into the inside of the arc-shaped slide groove, and then manually squeeze the two cover plates relative to each other, slide the sliding plate inside the slide groove, and pull the spring to make the cover plates fit together, and then manually push the grip to the right, and when the grip moves, it drives the slider to slide in the slide groove, and when the slider slides, it drives the L-shaped rod and the baffle to slide inward, and at the same time, the two power connectors fit together, and the drive motor is powered on through the wire, and then the two cover plates are pressed, and the cover plates rotate in the arc-shaped slide groove with the lower end of the cover plates as the center of the circle, and cover the mortar specimen; S2. After covering the mortar specimen, manually press the U-shaped frame. The U-shaped frame is on the side of the U-shaped base. The connecting rod is used as a fulcrum to lift the other side of the U-shaped frame upward, and then drive one end of the connecting rod 1 upward. The connecting rod 1 uses the other end of the U-shaped base as a fulcrum, and the other end of the connecting rod 1 rotates downward. The pressing plate on the side of the connecting rod 1 moves downward at the same time and presses the pressing plates on the top of the two cover plates, thereby fixing the two cover plates, and then closing the protective cover; S3, at this time, the driving motor in the power-on state is started, and the driving motor drives the eccentric wheel to rotate. When the eccentric wheel rotates, it drives the rectangular block fixed on the surface to slide on the rectangular slider, and when the eccentric wheel rotates upward or downward, it drives the rectangular slider to reciprocate up and down inside the vertical slide slot. At the same time, when the rectangular slider reciprocates, it drives the horizontal plate fixed on the side and the support rod fixed on the surface of the horizontal plate to move up and down at the same time, and the support rod drives the bottom plate fixed on the top to achieve vibration; S4. When an unqualified mortar specimen is encountered during normal testing, the mortar specimen will be shattered, and then the friction between the mortar specimen and the baffle will be lost. After the baffle loses resistance, the slider will be ejected by the spring and slide to the left. The slider will also drive the L-shaped rod to move. During the sliding process of the L-shaped rod, it will squeeze the push rod. After being squeezed, the push rod will rotate inside the telescopic groove. The push rod will rotate with the telescopic groove as the fulcrum, and the other end will rotate upward, and will lift the telescopic groove upward to half the height of the push rod. At the same time, the other end of the push rod will press the U-shaped The frame is lifted up, and the U-shaped frame is pressed on the side of the U-shaped base. The connecting rod is used as a fulcrum to lift the other side of the pressing U-shaped frame upward, and then drive one end of the connecting rod one downward, and the connecting rod one uses the other end of the U-shaped base as a fulcrum, and the other end of the connecting rod one rotates upward, and the pressing plate on the side of the connecting rod one moves upward at the same time, loosening the pressing plate, and at the same time the two cover plates lose their fixed points, and then slide outwards through the sliding block through the tension of the spring. After the two cover plates are separated, the power connector will also be separated at the same time, so that the drive motor will be in a power-off state and stop working; S5. When it is necessary to test the mortar specimen for a higher strength, the handle is pulled manually, and the handle pulls the telescopic rod to extend outward, and at the same time, the telescopic rod drives the block on the surface to extend outward. At this time, the block is separated from the slot, and then the handle is slid downward. The handle drives the sliding rod to slide downward inside the body through the telescopic rod, and the other end of the sliding rod will pull the L-shaped rod top rod to move downward, and the L-shaped rod top rod rotates on the surface of the fixed rod, so that the other end of the L-shaped rod is in a vertical state. At this time, the diamond piece will be vertical at the bottom of the bottom plate, and when the rectangular slider slides upward inside the vertical slot, the rectangular slider drives the upper connecting rod 1 upward, and when the connecting rod 1 moves upward, it will drive the connecting rod 2 upward, and the connecting rod 2 will use one side of the vertical slot as a fulcrum, and the other end of the connecting rod 2 will rotate downward, and the other end of the connecting rod 2 will rotate downward. When one end slides downward, it drives connecting rod three downward, and pushes sliding block one connected to the rotation of the lower end of connecting rod three to slide downward, and when the rectangular sliding block slides downward inside the vertical sliding groove, the rectangular sliding block drives connecting rod one at the upper end downward, and when connecting rod one moves upward, it drives connecting rod two downward, and connecting rod two uses one side of the vertical sliding groove as a fulcrum, and the other end of connecting rod two rotates upward, and when the other end of connecting rod two slides upward, it drives connecting rod three upward, and pulls sliding block one connected to the rotation of the lower end of connecting rod three to slide upward, forming relative sliding, and when sliding arc one slides, it drives the L-shaped top rod to slide at the same time through the fixed rod, so that when the bottom plate slides downward, it will hit the rhombus piece, and the rhombus piece itself is higher than the bottom plate, and at the same time it will be squeezed and deformed into a straight line, and then it will return to its original state through its own torsion spring rod; S6. When only ordinary testing is required, manually pull the handle, and the handle pulls the telescopic rod to extend outward. At the same time, the telescopic rod drives the card block on the surface to extend outward. At this time, the card block is separated from the card slot, and then slide the handle upward. The handle drives the sliding rod to slide downward inside the body through the telescopic rod. The other end of the sliding rod will pull the L-shaped rod top rod to move upward. The L-shaped rod rotates on the surface of the fixed rod, so that the other end of the L-shaped rod is tilted, so that the diamond piece will not contact the bottom plate.

[0011] In the present invention, after the mortar specimen is damaged, the pressure plate will be loosened, and the two cover plates will lose their fixing points. Then, through the pulling force of the spring, the sliding block will slide outward. After the two cover plates are separated, the power connector will also be separated at the same time, so that the drive motor will be in a power-off state and stop working. In this way, it will automatically disconnect after detecting inferior products, so that the staff can find unqualified products, and it will also ensure that a large amount of residue will not appear inside the machine body.

[0012] In the present invention, when the bottom plate slides downward, it will hit the diamond-shaped piece, which is higher than the bottom plate and will be squeezed and deformed into a straight line. Then, it will return to its original shape through its own torsion spring rod, so as to test the higher strength of the mortar specimen.

[0013] In the present invention, the L-shaped rod top rod is pulled upward by the other end of the sliding rod, and the L-shaped rod top rod rotates on the surface of the fixed rod, so that the other end of the L-shaped rod top rod is in an inclined state, so that the diamond-shaped piece will not contact the bottom plate, and ordinary detection can be performed, which is simple to operate and convenient to use.

[0022] The use method and advantages of the present invention: The adjustable cement mortar vibrating table and the use method thereof, when in use, the working process is as follows: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 As shown; A method for using an adjustable cement mortar vibrating table comprises the following steps: S1. First, place the mortar specimen on the surface of the bottom plate 31, and then manually rotate the cover plate 35. After the cylinders 36 on both sides of the two cover plates 35 are inserted into the arc-shaped slide groove 37, the two cover plates 35 are manually squeezed relative to each other, and the sliding plate 33 slides inside the slide groove 32, and the spring 34 is pulled to make the cover plates 35 fit together, and then the grip 46 is manually pushed to the right. When the grip 46 moves, it drives the slider 44 to slide in the slide groove 42. When the slider 44 slides, it drives the L-shaped rod 45 and the baffle 47 to slide inward. At the same time, the two power connectors 38 fit together, and the drive motor 61 is powered on through the wire 612. Then, the two cover plates 35 are pressed, and the cover plates 35 rotate in the arc-shaped slide groove 37 with the lower end of the cover plates 35 as the center of the circle, and cover the mortar specimen; S2. After covering the mortar specimen, the U-shaped frame 53 is manually pressed down. The U-shaped frame 53 is on the side of the U-shaped base 51. The connecting rod 52 is used as a fulcrum to lift the other side of the U-shaped frame 53 upward, and then one end of the connecting rod 1 54 is driven upward. The connecting rod 1 54 uses the other end of the U-shaped base 51 as a fulcrum, and the other end of the connecting rod 1 54 rotates downward. The pressing plate 55 on the side of the connecting rod 1 54 is simultaneously downward, and presses the pressing plates 41 at the top of the two cover plates 35, thereby fixing the two cover plates 35, and then the protective cover 2 is closed; S3, at this time, the driving motor 61 in the power-on state is started, and the driving motor 61 drives the eccentric wheel 62 to rotate. When the eccentric wheel 62 rotates, it drives the rectangular block 63 fixed on the surface to slide on the rectangular slider 65, and when the eccentric wheel 62 rotates upward or downward, it drives the rectangular slider 65 to reciprocate up and down inside the vertical slide 64. At the same time, when the rectangular slider 65 reciprocates, it drives the horizontal plate 610 fixed on the side and the support rod 611 fixed on the surface of the horizontal plate 610 to move up and down at the same time, and the support rod 611 drives the bottom plate 31 fixed on the top to realize vibration detection; S4. When an unqualified mortar specimen is encountered during normal testing, the mortar specimen will be shattered, and then the friction between the mortar specimen and the baffle 47 will be lost. After the baffle 47 loses resistance, the slider 44 will be ejected by the spring 43 and slide to the left. The slider 44 also drives the L-shaped rod 45 to move. During the sliding process, the L-shaped rod 45 will squeeze the push rod 57. After being squeezed, the push rod 57 will rotate inside the telescopic groove 56. The push rod 57 will rotate with the telescopic groove 56 as a fulcrum, and the other end will rotate upward, and the telescopic groove 56 will be pushed up to half the height of the push rod 57. At the same time, the other end of the push rod 57 will push the U-shaped frame 53 upward, and the U-shaped frame 53 will be pressed on the side of the U-shaped base 51 through the connecting rod 5 2 is a fulcrum, so that the other side of the U-shaped frame 53 is lifted up and then one end of the connecting rod 1 54 is driven downward, and the connecting rod 1 54 uses the other end of the U-shaped base 51 as a fulcrum, and the other end of the connecting rod 1 54 rotates upward, and the pressing plate 55 on the side of the connecting rod 1 54 is simultaneously upward, and the pressing plate 41 is loosened, and at the same time, the two cover plates 35 lose their fixed points, and then slide outward through the sliding block 33 by the pulling force of the spring 34. After the two cover plates 35 are separated, the power connector 38 will also be separated at the same time, so that the driving motor 61 will be in a power-off state and stop working. In this way, it will automatically disconnect after detecting inferior products, so that the staff can find unqualified products, and at the same time, it will ensure that there will be no large amount of residue inside the body 1; When the handle 78 is manually pulled, the handle 78 pulls the telescopic rod 76 to extend outward, and the telescopic rod 76 drives the block 77 on the surface to extend outward. At this time, the block 77 is separated from the slot 75, and then the handle 78 is slid downward. The handle 78 drives the sliding rod 74 to slide downward inside the body 1 through the telescopic rod 76. The other end of the sliding rod 74 pulls the L-shaped rod top rod 72 to move downward. The L-shaped top rod 72 rotates on the surface of the fixed rod 71, so that the other end of the L-shaped top rod 72 is in a vertical state. At this time, the diamond piece 73 will be vertical at the bottom of the bottom plate 31, and when the rectangular slide block 65 slides upward inside the vertical slide groove 64, the rectangular slide block 65 drives the upper end of the connecting rod 1 66 upward. At the same time, when the connecting rod 1 66 moves upward, it will drive the connecting rod 2 67 upward, and the connecting rod 2 67 will use one side of the vertical slide groove 64 as a fulcrum, and the other end of the connecting rod 2 67 will rotate downward. The other end of the connecting rod 2 67 When sliding downward, it drives the connecting rod 3 68 downward, and pushes the sliding block 1 69 connected to the lower end of the connecting rod 3 68 to slide downward, and when the rectangular sliding block 65 slides downward inside the vertical sliding groove 64, the rectangular sliding block 65 drives the connecting rod 1 66 at the upper end downward, and at the same time, when the connecting rod 1 66 moves upward, it drives the connecting rod 2 67 downward, and the connecting rod 2 67 uses one side of the vertical sliding groove 64 as a fulcrum, and the other end of the connecting rod 2 67 rotates upward. When the other end of the connecting rod 2 67 slides upward, it drives the connecting rod 3 68 upward, and pulls the sliding block 1 69 connected to the lower end of the connecting rod 3 68 to slide upward, forming relative sliding. When the sliding arc 1 69 slides, it drives the L-shaped top rod 72 to slide at the same time through the fixed rod 71. In this way, when the bottom plate 31 slides downward, it will hit the diamond piece 73. The diamond piece 73 itself is higher than the bottom plate 31, and at the same time it will be squeezed and deformed into a straight line, and then restored to its original state through its own torsion spring rod, so as to test the higher strength of the mortar specimen; S6. When only ordinary inspection is needed, the handle 78 is manually pulled, and the handle 78 pulls the telescopic rod 76 to extend outward. At the same time, the telescopic rod 76 drives the block 77 on the surface to extend outward. At this time, the block 77 is separated from the slot 75, and then the handle 78 is slid upward. The handle 78 drives the sliding rod 74 to slide downward inside the body 1 through the telescopic rod 76. The other end of the sliding rod 74 will pull the L-shaped rod top rod 72 to move upward. The L-shaped top rod 72 rotates on the surface of the fixed rod 71, so that the other end of the L-shaped top rod 72 is in an inclined state. In this way, the diamond-shaped piece 73 will not contact the bottom plate 31, and ordinary inspection can be performed. The operation is simple and convenient to use.

8. A method for using an adjustable cement mortar vibrating table, characterized in that: The following steps are involved: S1. First, place the mortar specimen on the surface of the bottom plate (31), and then manually rotate the cover plate (35) to insert the cylinders (36) on both sides of the two cover plates (35) into the interior of the arc-shaped slide groove (37). Then, manually squeeze the two cover plates (35) relative to each other, slide the sliding plate (33) inside the sliding groove (32), and pull the spring (34) to make the cover plates (35) fit together. Then, manually push the handle (46) to the right, and the handle (46) is pushed to the right. 6) When moving, the slider (44) is driven to slide in the slide groove (42), and when the slider (44) slides, the L-shaped rod (45) and the baffle (47) are driven to slide inward, and at the same time, the two power connectors (38) are fitted together, and the drive motor (61) is powered through the wire (612), and then the two cover plates (35) are pressed, and the cover plates (35) rotate in the arc-shaped slide groove (37) with the lower end of the cover plates (35) as the center of the circle, and cover the mortar specimen; S2. After covering the mortar specimen, the pressing U-shaped frame (53) is manually pressed down. The pressing U-shaped frame (53) is on the side of the U-shaped base (51). The connecting rod (52) is used as a fulcrum to lift the other side of the pressing U-shaped frame (53) upward, and then drive one end of the connecting rod 1 (54) upward. The connecting rod 1 (54) uses the other end of the U-shaped base (51) as a fulcrum, and the other end of the connecting rod 1 (54) rotates downward. The pressing plate (55) on the side of the connecting rod 1 (54) is simultaneously moved downward and presses the pressing plates (41) at the top ends of the two cover plates (35), thereby fixing the two cover plates (35), and then closing the protective cover (2); S3, at this time, the driving motor (61) in the power-on state is started, and the driving motor (61) drives the eccentric wheel (62) to rotate. When the eccentric wheel (62) rotates, it drives the rectangular block (63) fixedly connected to the surface to slide on the rectangular slider (65), and when the eccentric wheel (62) rotates upward or downward, it drives the rectangular slider (65) to reciprocate up and down inside the vertical slide groove (64). At the same time, when the rectangular slider (65) reciprocates, it drives the horizontal plate (610) fixedly connected to the side and the support rod (611) fixed on the surface of the horizontal plate (610) to move up and down at the same time, and the support rod (611) drives the bottom plate (31) fixed at the top to vibrate; S4. When an unqualified mortar specimen is encountered during normal testing, the mortar specimen will be shattered, and then the friction between the mortar specimen and the baffle (47) will be lost. After the baffle (47) loses resistance, the slider (44) will be ejected by the spring (43) and slide to the left. The slider (44) will also drive the L-shaped rod (45) to move. During the sliding process, the L-shaped rod (45) will squeeze the push rod (57). After being squeezed, the push rod (57) will rotate inside the telescopic groove (56). The push rod (57) will rotate with the telescopic groove (56) as a fulcrum, and the other end will rotate upward, and will push the telescopic groove (56) upward to half the height of the push rod (57). At the same time, the other end of the push rod (57) will press the U-shaped frame (53) to The U-shaped frame (53) is lifted up, and the U-shaped frame (53) is pressed on the side of the U-shaped base (51). The connecting rod (52) is used as a fulcrum to lift the other side of the U-shaped frame (53) upward, and then drive one end of the connecting rod (54) downward. The connecting rod (54) uses the other end of the U-shaped base (51) as a fulcrum, and the other end of the connecting rod (54) rotates upward. The pressing plate (55) on the side of the connecting rod (54) is simultaneously moved upward to release the pressing plate (41). At the same time, the two cover plates (35) lose their fixed points, and then slide outward through the pulling force of the spring (34) and the sliding block (33). After the two cover plates (35) are separated, the power connector (38) is also separated at the same time, so that the drive motor (61) is in a power-off state and stops working; S5. When it is necessary to test the mortar specimen for a higher strength, the handle (78) is manually pulled, and the handle (78) pulls the telescopic rod (76) to extend outward, and at the same time, the telescopic rod (76) drives the block (77) on the surface to extend outward. At this time, the block (77) is separated from the slot (75), and then the handle (78) is slid downward. The handle (78) drives the sliding rod (74) to slide downward inside the body (1) through the telescopic rod (76). The other end of the sliding rod (74) pulls the L-shaped rod top rod (72) to move downward, and the L-shaped top rod (72) is moved downward. The rod (72) rotates on the surface of the fixed rod (71) so that the other end of the L-shaped top rod (72) is in a vertical state. At this time, the diamond-shaped piece (73) will be vertically at the bottom of the bottom plate (31). When the rectangular slider (65) slides upward inside the vertical slide groove (64), the rectangular slider (65) drives the upper end of the connecting rod (66) upward. At the same time, when the connecting rod (66) moves upward, it will drive the connecting rod (67) upward. The connecting rod (67) will use one side of the vertical slide groove (64) as a fulcrum, and the other end of the connecting rod (67) will move downward. When the other end of the second connecting rod (67) slides downward, it drives the third connecting rod (68) downward, and pushes the slider (69) connected to the lower end of the third connecting rod (68) to slide downward. When the rectangular slider (65) slides downward inside the vertical slide groove (64), the rectangular slider (65) drives the first connecting rod (66) at the upper end downward. At the same time, when the first connecting rod (66) moves upward, it drives the second connecting rod (67) downward. The second connecting rod (67) uses one side of the vertical slide groove (64) as a fulcrum, and the other end of the second connecting rod (67) moves upward. When the other end of the second connecting rod (67) slides upward, it drives the third connecting rod (68) upward, and pulls the sliding block (69) connected to the lower end of the third connecting rod (68) to slide upward, thereby forming a relative sliding movement. When the sliding block (69) slides, it drives the L-shaped top rod (72) to slide at the same time through the fixed rod (71). In this way, when the bottom plate (31) slides downward, it will hit the diamond-shaped piece (73). The diamond-shaped piece (73) itself is higher than the bottom plate (31) and is squeezed and deformed into a straight line shape, and then restored to its original shape through its own torsion spring rod; S6. When only ordinary testing is required, the handle (78) is manually pulled, and the handle (78) pulls the telescopic rod (76) to extend outward. At the same time, the telescopic rod (76) drives the block (77) on the surface to extend outward. At this time, the block (77) is separated from the slot (75), and then the handle (78) is slid upward. The handle (78) drives the sliding rod (74) to slide downward inside the body (1) through the telescopic rod (76). The other end of the sliding rod (74) pulls the L-shaped rod top rod (72) to move upward. The L-shaped rod top rod (72) rotates on the surface of the fixed rod (71), so that the other end of the L-shaped rod top rod (72) is tilted, so that the diamond-shaped piece (73) will not contact the bottom plate (31).
