[0029] A spiral guide groove 51 is provided on the outer wall of the rotating drum 5, and a connecting piece 81 is provided on the supporting frame 1. The connecting piece 81 is fixedly connected to the limiting ball 8, and the limiting ball 8 is cooperated and arranged in the spiral guide groove 51; a limiting cylinder 7 is provided on the outside of the rotating drum 5, the limiting cylinder 7 is coaxial with the rotating drum 5, and the rotating drum 5 is rotatably arranged on the limiting cylinder 7 through a bearing; at the same time, two sliding sleeves 21 are embedded in the bearing seat 2, and the two sliding sleeves 21 are vertically arranged. Two guide rods 71 ​​are fixedly connected to the top of the limiting ring, and the two guide rods 71 ​​are vertically arranged. The two guide rods 71 ​​pass through the two sliding sleeves 21 respectively, and the guide rods 71 ​​are adapted to the sliding sleeves 21. Through the cooperation of the guide rods 71 ​​and the sliding sleeve 21, after the fixing component 9 loosens the rotating drum 5, the limiting ring can be moved up and down.

[0030] The connecting member 81 includes a connecting seat 811 fixedly provided on the supporting frame 1 , and a connecting column 812 fixedly provided on the connecting frame. The connecting column 812 is horizontally arranged and fixedly connected to the limiting ball 8 .

[0031] The slide rod 4 consists of a cylindrical portion 42 and a rod portion 41, and the rod portion 41 is a square rod structure; the bottom end of the cylindrical portion 42 is fixedly connected to the test cone 6, and the cylindrical portion 42 is coaxial with the test cone 6 and the rotating drum 5. Multiple groups of rolling support assemblies 53 are all arranged on the rod portion 41, and a scale is set on the rod portion 41.

[0032] Two guide rails 12 are fixedly provided on the support frame 1, the guide rails 12 are vertically arranged, and the two guide rails 12 are symmetrically arranged; guide pulleys 10 are provided on the outer walls of the two opposite sides of the rod 41, and the two guide pulleys 10 are symmetrically arranged. The two guide pulleys 10 are respectively matched with the two guide rails 12; the guide pulleys 10 cooperate with the guide rails 12 to ensure that the rod 41 moves vertically and cannot rotate.

[0033] Each group of rolling bearing assemblies 53 includes four universal balls 531, which are evenly distributed on the outer wall of the rod 41. That is, a universal ball 531 is fixedly provided on each outer wall of each rod 41, and the ball of each universal ball 531 is in contact with the inner wall of the drum 5.

[0034] The fixing assembly 9 includes an annular electromagnet 91 fixedly mounted on the supporting seat 2, and the rod portion 41 passes through the annular electromagnet 91; the fixing assembly 9 also includes a first iron ring 92 and a second iron ring 93, the second iron ring 93 is fixedly sleeved on the outside of the rod portion 41, and the first iron ring 92 is fixedly arranged at the top end of the rotating drum 5. The first iron ring 92 and the second iron ring 93 correspond to the adsorption areas of the annular electromagnet 91, that is, by energizing the annular electromagnet 91, the first iron ring 92 and the second iron ring 93 can be adsorbed, thereby further realizing the position fixation of the rotating drum 5, the stirring member 52, the test cone 6, etc.; of course, the annular electromagnet 91 has a strong adsorption ability.

[0035] The stirring member 52 includes an annular weighted block 521 fixedly disposed at the bottom end of the rotating drum 5, and the annular weighted block 521 is coaxial with the rotating drum 5; a spiral stirring blade 522 is fixedly disposed at the bottom end of the annular weighted block 521; Figure 3 As shown, in the initial state, the first iron ring 92 and the second iron ring 93 are adsorbed by the annular electromagnet 91, and the spiral stirring blade 522 is located outside the test cone 6. At this time, the lowest end of the spiral stirring blade 522 is slightly higher than the lowest end of the test cone 6; in addition, at this time, the test cone 6 and the spiral stirring blade 522 correspond to the mortar tube 13, and the test cone 6 and the spiral stirring blade 522 are located above the mortar tube 13.

[0036] In this embodiment, the mortar to be tested (hereinafter referred to as mortar) is first filled into the mortar tube 13. After the upper surface of the mortar is stable and flat, the lifting assembly 3 drives the supporting seat 2 to move downward. During this process, the annular electromagnet 91 adsorbs the first iron ring 92 and the second iron ring 93, thereby driving the rotating drum 5, the slide rod 4, the test cone 6 and the spiral stirring blade 522 to move downward. When the bottom end steel of the test cone 6 contacts the upper surface of the mortar, the driving of the supporting seat 2 to continue moving can be stopped.

[0037] Then, the power is cut off by the annular electromagnet 91. At this time, under the action of gravity, the test cone 6 and the rotating drum 5 both descend, thereby driving the spiral stirring blades 522 to descend; since the rotating drum 5 is in contact with the universal ball 531, the rotating drum 5 is rotatably set on the limit cylinder 7, and the limit ball 8 cooperates with the spiral guide groove 51, so the rotating drum 5 also rotates during the descent process, thereby driving the spiral stirring blades 522 to rotate; therefore, in the process of the test cone 6 settling the mortar, the spiral stirring blades 522 also settle the mortar and stir the mortar, thereby ensuring that the activity of the mortar can be maintained during the test process, which helps to improve the detection accuracy; at the same time, industrial cameras, electronic digital displays and other devices can be installed on the support frame 1 to scan the scale on the detection rod 41, so as to obtain the sedimentation depth in the mortar, so as to judge or calculate the consistency of the mortar.

[0038] After the detection is completed, the supporting seat 2 is driven down by the lifting component 3, and the annular electromagnet 91 is energized again. When the annular electromagnet 91 is close to the first iron ring 92 and the second iron ring 93, the annular electromagnet 91 re-adsorbs the first iron ring 92 and the second iron ring 93. After the annular electromagnet 91 adsorbs the first iron ring 92 and the second iron ring 93, the lifting component 3 drives the supporting seat 2 to reset upward; during the upward resetting process of the supporting seat 2, the rotating drum 5 will rotate at the same time during the upward movement, so as to facilitate the removal of the mortar attached to the spiral stirring blade 522, and thus facilitate the subsequent cleaning of the spiral stirring blade 522; finally, the mortar barrel 13 is taken out, the mortar is poured out and the mortar barrel 13 is cleaned.

[0039] In this embodiment, during the sedimentation of the mortar by the test cone 6, the spiral stirring blades 522 also sediment the mortar and stir the mortar, which helps to maintain the activity of the mortar during the test and helps to improve the detection accuracy; at the same time, the two guide pulleys 10 cooperate with the two guide rails 12 to limit the rotation of the slide bar 4, thereby ensuring that the test cone 6 does not rotate during the sedimentation process, which helps to improve the test accuracy; in addition, by arranging multiple universal balls 531 on the rod portion 41, the contact between the universal balls 531 and the rotating drum 5 has a limiting effect on the slide bar 4 on the one hand, reducing or avoiding the deflection or offset of the slide bar 4, helping to ensure that the test cone 6 will not offset, and further improving the test accuracy; on the other hand, the universal ball 531 contacts the inner wall of the rotating drum 5, which does not affect the rotation of the rotating drum 5; that is, in summary, the test accuracy can be effectively improved.

[0040] Example 2 See again Figure 1 、 Figure 2 as well as Figure 7This embodiment is based on the first embodiment. The lifting assembly 3 includes a nut seat 31 movably set on the support frame 1, and the nut seat 31 is fixedly connected to the bearing seat 2; a screw rod 32 is threadedly engaged on the nut seat 31, and the screw rod 32 is movably set on the support frame 1 through a bearing, and the screw rod 32 is vertically set; the lifting assembly 3 also includes a driving motor 33, and the output end of the driving motor 33 is fixedly connected to the top of the screw rod 32.

[0041] Two linear slide rails 34 are vertically arranged on the support frame 1, and sliders 35 are provided on the two linear slide rails 34. All sliders 35 are fixedly connected to the nut seat 31; the screw rod 32 is driven to rotate by the driving motor 33, thereby driving the nut seat 31 to move up and down, thereby realizing the lifting of the supporting seat 2, and further realizing the lifting of the rotating drum 5, the spiral stirring blade 522, etc.

[0042] Example 3 See again Figure 2 and Figure 7 This embodiment is based on the second embodiment, and a placement groove 11 adapted to the mortar barrel 13 is provided on the support frame 1, and the bottom end of the mortar barrel 13 is used to be placed in the placement groove 11; by cooperating with the mortar barrel 13 through the placement groove 11, the mortar barrel 13 is conveniently and stably placed, and at the same time the mortar barrel 13 can be taken out to fill mortar or clean the mortar barrel 13.
