One end of the adjusting seat 32 far away from the guide rod 31 is connected with a positioning bolt 35 through a thread, and the positioning bolt 35 penetrates through the adjusting seat 32 to be abutted against the side wall of the connecting rod 121. When the mortar is measured, the mortar is placed in the mortar containing barrel 11, the distance between the mortar and the upper end face of the mortar containing barrel 11 is determined by the scale 111, the lower end of the test cone 12 is moved to be flush with the upper end of the mortar containing barrel 11, the distance obtained by the scale 111 is continuously moved downwards, the distance of the test cone 12 extending into the mortar containing barrel 11 is determined by the measuring scale 34, the lower end of the test cone 12 is in contact with the mortar but does not extend into the mortar, the position of the test cone 12 is determined by the scale 111 and the measuring scale 34 at the moment, the stop position of the test cone 12 is more accurate, and the detection result of the mortar consistency is not easily influenced.

As shown in figure 1, errors are still easy to generate at the moment because the positions of the lower end of the test cone 12 and the upper end surface of the pulp containing barrel 11 are still observed by naked eyes. Therefore, the upper end of the bracket is connected with a limiting block 13 for limiting the position of the test cone 12, and the upper end of the limiting block 13 is penetrated with a guide groove 131. An installation block 14 is integrally formed at the upper end of the support 1, the upper end face of the installation block 14 and the upper end face of the pulp containing barrel 11 are in the same plane, the limiting block 13 is arranged at the upper end of the installation block 14 to slide, and the lower end of the limiting block 13 and the upper end of the pulp containing barrel 11 are in the same plane.

The position of the test cone 12 is limited by the limiting block 13, and the position of the test cone 12 is more accurate when the test cone moves downwards to be in contact with the upper end of the mortar, so that the measurement result of the mortar consistency is more accurate.

As shown in fig. 2, because the lower end of the test cone 12 is sharp, the lower end of the test cone 12 has lower strength, and the lower end of the test cone is easy to deform when contacting the upper end of the limit block 13, so as to affect the subsequent measurement result, the limit groove 132 penetrates through the upper end surface of the limit block 13, the limit groove 132 penetrates through the end surface of the limit block far away from the guide rod 31, the lower end of the test cone 12 is inserted into the limit groove 132, and the depth of the test cone 12 inserted into the limit groove 132 is equal to the thickness of the limit block. The lower end of the test cone 12 is not directly contacted with the upper end of the limiting block by utilizing the limiting groove 132, so that the lower end surface of the test cone 12 is not easy to deform, and the measurement result of the mortar consistency is not easy to be influenced.

As shown in fig. 2, in order to further prevent the test cone 12 from being deformed, the inner wall of the limiting groove 132 is provided with a positioning wedge surface 133, the upper ends of the positioning wedge surfaces 133 are far away from each other, and the positioning wedge surfaces 133 abut against the side wall of the test cone 12.

As shown in fig. 1 and 3, the measuring mechanism 2 includes a measuring disc 21 connected to the support 1, a reading disc 22 coaxially connected to the measuring disc 21, a pointer 23 rotatably connected to the measuring disc 21, a first gear 24 rotatably connected to the measuring disc 21, and a rack 25 slidably connected to the measuring disc 21. The welding of guide bar 31 upper end has an installation pole 36, measuring disc 21 uses the bolt fastening to install the pole and keep away from the one end of guide bar 31, reading disc 22 sets up in the one side that the installation pole was kept away from to measuring disc 21, pointer 23 sets up in the one end that measuring disc 21 was kept away from to reading disc 22, and pointer 23 uses bolted connection to have pivot 26, pivot 26 is coaxial to be passed reading disc 22 and measuring disc 21 and uses parallel key coaxial coupling with first gear 24, measuring disc 21 is connected with the terminal surface rotation of first gear 24 and is connected with second gear 27, the number of teeth of second gear 27 is less than the number of teeth of second gear 27. The rack 25 slides vertically along the measuring disc 21, which is attached to the second gear 27, and the lower end of the rack 25 abuts against the upper end of the connecting rod 121. When the lower end of the test cone 12 is in contact with the upper end of the mortar, the lower end of the rack 25 is in contact with the upper end of the connecting rod 121, the reading of the reading disc 22 pointed by the pointer 23 is read, then the test cone 12 moves downwards for ten seconds, the rack 25 is in contact with the upper end of the connecting rod 121 again, the reading of the reading disc 22 pointed by the pointer 23 is read, and the two readings are subtracted to obtain a required numerical value.

As shown in fig. 1, since the amount of mortar placed in the mortar containing barrel 11 at each time cannot be controlled, when the rack 25 is first contacted with the connecting rod 121 to read the reading pointed by the pointer 23, the pointer 23 cannot point at the zero scale 111 of the reading disc 22, which causes the subsequent calculation process to be troublesome. The reading disk 22 is thus rotatably connected to the measuring disk 21, the axis of rotation of the reading disk 22 coincides with the axis of rotation of the pointer 23, and the end face of the reading disk 22 remote from the measuring disk 21 is threadedly connected to the fastening bolt 28, and the fastening bolt 28 passes through the reading disk 22 and abuts against the end face of the measuring disk 21. At this time, when the scale 111 is in contact with the connecting rod 121 for the first time, the reading disc 22 is rotated to enable the pointer 23 to point at the zero scale 111 line of the reading disc 22, and at this time, subtraction is no longer needed when reading the second reading, so that the process of data is more convenient.
