Detailed Description

As shown in fig. 1, the utility model provides a cement mortar stirring test equipment of using, which comprises a base 1, rack 2, actuating mechanism 3, stirring leaf 4, agitator kettle 5 and second actuating mechanism 6, base 1 is placed in the workstation top, rack 2 is connected with base 1, agitator kettle 5 places in the top of rack 2, actuating mechanism 3 fixes in the top of base 1, actuating mechanism 3 drive stirring leaf 4 is around vertical axle rotation, second actuating mechanism 6 sets up on rack 2, second actuating mechanism 6 can drive agitator kettle 5 and rotate along vertical center pin, stirring

leaf

4 and 5 disalignment of agitator kettle, eccentric setting promptly, and stirring leaf 4 global and agitator kettle 5's inside wall contact when rotating 4. Starting drive mechanism 3, drive mechanism 3 can drive 4 rotations of stirring leaf, start second actuating mechanism 6, second actuating mechanism 6 can drive 5 rotations of stirred tank, because stirring

leaf

4 and 5 eccentric settings of stirred tank, and stirring leaf 4 when rotating global and stirred tank 5's inside wall contact, consequently stirring leaf 4 can scrape the material of 5 lateral walls departments of stirred tank and mix through the stirring of stirring leaf 4, can form good stirring effect. And actuating mechanism 3 and second actuating mechanism 6 can drive stirring leaf 4 alone and rotate and stirred tank 5 rotates, consequently can adjust stirred tank 5 and the slew velocity of stirring leaf 4 at any time according to the condition of difference, can compromise stirring efficiency and stirring quality simultaneously.

Because the stirring pot 5 needs to add and take and put the material frequently, especially need to pour the material after the stirring pot 5 takes out in order to shape the test piece after the stirring, therefore stirring pot 5 must be detachable, just so use conveniently, and in case stirring pot 5 sets up to be detachable, has had the requirement to the connected mode of second actuating mechanism 6 and stirring pot 5 so. In this embodiment, as shown in fig. 2, a rotating disc 21 is arranged on the placing rack 2, the rotating disc 21 is rotatably connected with the placing rack 2 through a vertical shaft, a vertical insertion hole 211 is formed in the rotating disc 21, an insertion rod 51 in insertion fit with the insertion hole 211 is fixedly arranged below the stirring pot 5, and the second driving mechanism 6 can drive the rotating disc 21 to rotate. The second driving mechanism 6 drives the stirring pot 5 to rotate by driving the rotating disc 21 to rotate, and the stirring pot 5 and the rotating disc 21 are in insertion fit, so that the stirring pot 5 is convenient to take and place, and the stirring pot 5 is driven to rotate more stably.

In order to further improve the convenience of installing and disassembling the stirring pot 5, as shown in fig. 1, the placing frame 2 can be set to be a lifting structure, namely, a part of the placing frame 2 is inserted into the base 1, a sliding groove 11 for the placing frame 2 to vertically slide is formed in the base 1, a lifting driving structure capable of driving the placing frame 2 to vertically lift is arranged in the base 1, and the lifting driving structure is generally a screw slider mechanism.

The driving mechanism 3 and the second driving mechanism 6 are generally in a gear transmission structure, because the gear transmission structure has a compact structure and stable transmission, of course, a belt transmission structure or a chain transmission structure can also be adopted.

In the process of stirring materials, the materials still need to be added into the stirring pot 5 under certain conditions to form cement mortar with certain special requirements, and the direct addition of the materials into the stirring pot 5 is difficult and the materials are easy to scatter. In order to solve the above problem, as shown in fig. 1, a charging barrel 7 may be fixedly connected to the base 1, a charging opening 71 is formed at an upper end of the charging barrel 7, a discharging pipe 72 is communicated with a lower end of the charging barrel 7, and a discharging opening of the discharging pipe 72 is located above the stirring pot 5. The discharging pipe 72 is preferably located on one side of the stirring pot 5 with the center deviating from the stirring blade 4, so that the material added into the discharging pipe 72 is more stable, the added material can be kept away from the stirring blade 4, and the situation that the added material directly collides with the stirring blade 4 in a contact manner to generate splashing is avoided. In the stirring process, the materials can be fed into the feeding barrel 7 through the feeding port 71, and the added materials can enter the stirring pot 5 from the discharging pipe 72 and are stirred and mixed with the materials, so that the materials can be added in the stirring process conveniently.

As shown in fig. 1, the form of the stirring vane 4 is also various, in this embodiment, the stirring vane 4 includes a stirring shaft 41, a main vane 42 and a scraping vane 43, the stirring shaft 41 is vertical, the main vane 42 is fixedly connected to the stirring shaft 41, and the scraping vane 43 is fixedly connected to the main vane 42. The main blade 42 mainly plays a role in supporting the scraping blade 43 and stirring materials, and the scraping blade 43 mainly plays a role in scraping off materials on the edge of the side wall of the stirring pot 5, so that the materials on the edge of the stirring pot 5 can be fully stirred.

In order to ensure the dynamic balance of the stirring blade 4 during the rotation process, the main blade 42 and the scraping blade 43 need to be arranged relatively uniformly relative to the stirring shaft 41, that is, the center of gravity of the stirring blade 4 is located on the stirring shaft 41. As shown in fig. 1, in order to optimize the structure of the stirring vanes 4 and facilitate the processing of the stirring vanes 4, the main vanes 42 are divided into two or more groups, each group of main vanes 42 is located in the same vertical plane, each group of main vanes 42 is uniformly arranged along the stirring shaft 41 at intervals, the scraping vanes 43 also include a plurality of main vanes, and the scraping vanes 43 may be spirally arranged or may be individually fixed on each group of main vanes 42. No matter how the scraping blade 43 is arranged, the outer contour of the scraping blade 43 is ensured to be matched with the contour shape of the inner side wall of the stirring pot 5, so that the attaching degree of the scraping blade 43 and the stirring pot 5 is higher, and the scraping effect of the inner side wall of the stirring pot 5 can be improved.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
