Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, the cement mortar fluidity detector disclosed by the utility model comprises a base and a frame 1 fixed on the base, wherein a circular sand table 2 is connected on the frame 1 in a vertical sliding manner, a truncated cone round mold 3 is transversely arranged at the center of one side of the sand table 2 departing from the frame 1, and an adaptive sleeve mold 4 is arranged at one end of the truncated cone round mold 3 departing from the sand table 2; a reciprocating driving mechanism for driving the sand disc 2 to vertically move is also connected to the frame 1.

During the use, stack in the central point that has been cleaned sand table 2 from the top down in proper order earlier cover die 4 and truncated cone circle mould 3 and put, again with the mortar two-layer packing in the mould, utilize the tamper evenly to insert and smash after that, then take off cover die 4, scrape the unnecessary mortar of unnecessary mortar, later upwards lift truncated cone circle mould 3 perpendicularly gently, open reciprocating drive mechanism at last and order about the vertical reciprocating motion (vibrations) of sand table 2 and can do the mortar mobility and detect.

Referring to fig. 2, the base is plate-shaped, and the frame 1 is trapezoidal in front view. The driving mechanism comprises a motor 9 arranged on the base, an output shaft of the motor 9 transversely (based on a working state) penetrates into the rack 1, and a cam 91 is fixed at the end head; the upper portion of the frame 1 is vertically slidably connected to a link 92, the lower end of the link 92 is formed into an elliptical shape and abuts against the tread of the cam 91, and the upper end is fixed to the center point of the sand table 2.

The motor 9 is started to drive the cam 91, the cam 91 rotates to drive the connecting rod 92 which is abutted to the wheel surface of the cam to reciprocate and vertically slide, and the connecting rod 92 drives the sand disc 2 to reciprocate, lift (vibrate) so as to detect the fluidity of the mortar.

Referring to fig. 3 and 4, the palette 2 is divided into a first tray 21 and a second tray 22 which are stacked one on another, wherein the first tray 21 is positioned at an upper level and the first tray 21 has a larger diameter than the second tray 22; a hinge groove 24 is formed at the central position of one side of the second tray 22 close to the first tray 21, a hinge 25 slides in the hinge groove 24, the hinge 25 is fixed on a hinge rod 26, and the other end of the hinge rod 26 is fixed at the central position of one side of the first tray 21 close to the second tray 22, at this time, the axes of the two trays are connected in a ball hinge manner, so that the two trays can rotate relatively.

Referring to fig. 3, since the first tray 21 cannot rotate relative to the second tray 22 during the inspection, a plurality of intermediate blocks are inserted between the two trays; in order to prevent the middle block from being separated during the vibration of the sand table 2 and affecting the use effect, the middle block is an electromagnet 7, and the first tray 21 and the second tray 22 are magnetizable (e.g. iron) tray bodies.

The electromagnet 7 is switched on in the detection process so as to be fixed between the first tray 21 and the second tray 22; when it needs to be taken out, it is powered off.

A cushion block 8 made of rubber is glued and fixed on the end face of the electromagnet 7 facing the first tray 21 or the second tray 22; when the electromagnet 7 is clamped between the first tray 21 and the second tray 22, the cushion block 8 is compressed, and the supporting effect of the electromagnet 7 on the first tray 21 and the second tray 22 is better.

Referring to fig. 3 and 4, a water tank 5 having a U-shaped cross section as viewed from the end is disposed around the outer edge of the first tray 21, and the bottom of the water tank 5 is lower than the first tray 21 in the vertical direction; in order to fix the water tank 5 on the first tray 21, a snap ring 211 having a U-shaped cross-section and an opening facing the first tray 21 is welded and fixed to one side of the water tank 5 close to the first tray 21, and the snap ring 211 is snapped to an outer edge of the first tray 21, thereby fixing the water tank 5 and the first tray 21.

Referring to fig. 3 and 4, in order to make the water tank 5 attachable and detachable with respect to the first tray 21, the water tank 5 is divided into two along a certain diameter direction thereof and includes a first tank 51 and a second tank 52, respectively.

The use process comprises the following steps: when the sand tray 2 (the first tray 21) needs to be cleaned after the mortar detection is finished, a worker firstly closes the electromagnet 7 and takes out part of the electromagnet 7 from the first tray 21 and the second tray 22; then, the water tank 5 is arranged on the first tray 21, and then part of clear water is taken to clean the upper surface of the first tray 21; the sewage after the washing strikes off and makes it flow to basin 5, this moment the utility model discloses a first tray 21 obtains more abundant clearance, and the clearance effect is better and recoverable partial gluey sand relatively to the result of use is better.

In order to facilitate the sewage to flow into the water tank 5, a plurality of flow grooves 212 are formed in the upper surface of the first tray 21 of the snap ring 211 along the radial direction of the first tray 21, and the flow grooves 212 are uniformly distributed around the snap ring 211 and communicated with the water tank 5.

In order to conveniently take out the electromagnet 7, a pull rope 71 is fixed on the side wall of the electromagnet, and a pull ring 72 is fixed at one end of the pull rope 71, which is far away from the electromagnet 7. So that the worker can take the pull ring 72 to pull the electromagnet 7.

Referring to fig. 4, in order to enhance the sealing performance after the snap ring 211 and the first tray 21 are clamped, a sealing sheet 6 is fixed by gluing on one side of the snap ring 211 facing the upper surface of the second tray 22; furthermore, the surface of the sealing sheet 6 contacting with the first tray 21 is serrated, so that the friction and the sealing degree are enhanced, and the using effect is better.

Referring to fig. 1, the outer sides of one ends of the first and

second slots

51 and 52 are hinged by a hinge; a lock catch 511 is hinged and installed on the outer side of the other end of the first groove 51, a lock bait 512 with a through hole and matched with the lock catch 511 is fixed on the outer side of the other end of the second groove 52, and a pin 513 is matched in the hole of the lock bait 512.

When the lock catch 511 is installed, the lock catch 511 is buckled on the lock bait 512, and then the lock catch and the pin 513 are inserted into the hole of the lock bait 512. The first slot 51 and the second slot 52 are connected together, so that the taking and using effects are convenient.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
