The support is in a "door-shaped" structure, and a through hole is formed in one side of the support. The stirring device is fixedly connected to the center position of the bottom of the support beam. The rotating device is movably connected to the through hole formed in the left side of the support, and the rotating device extends to one end of the bottom of the support and is movably connected with the stirring device. The stirring barrel is arranged below the support, and the stirring device is arranged above the stirring barrel. The mixing device for the drilling fluid anti-sloughing agent is improved to have a simple structure, and the support, the rotating device and the stirring device can be separated. If the structure is damaged, the operator can repair the damaged part, thereby effectively improving the work efficiency during maintenance. Moreover, the internal damaged parts can be replaced or repaired in time, and the structure is simple and practical.

[0003] In the above-mentioned technology, the mixing device for the drilling fluid anti-sloughing agent stirs the anti-sloughing agent in the stirring barrel through the stirring device. In actual operation, since the specifications of the containers for storing the anti-sloughing agent are different, it is difficult to ensure that the stirring device can completely adapt to the containers for the anti-sloughing agent, thereby easily limiting the use range and flexibility of the device.

Further, the driving assembly also drives the linkage assembly to rotate the support sleeve, so that the support sleeve rotates and drives the anti-collapse agent container to rotate, so that the stirring rod can reciprocatingly stir the anti-collapse agent in the anti-collapse agent container at different depths, and the rotation of the support sleeve not only improves the stirring efficiency of the anti-collapse agent, but also realizes uniform mixing of the anti-collapse agent.

In this way, through the stable connection of the belt transmission and the gear engagement, not only the accurate transmission of the rotation is realized, but also the low friction and high efficiency in the rotation process are ensured, thereby ensuring the mixing effect of the anti-collapse agent.

[0022] As a preferred scheme, the guiding wheels are uniformly arranged on the lower end surface of the supporting sleeve, and the guiding grooves are arranged on the upper end surface of the fixed base and matched with the guiding wheels. The guiding grooves are arranged circumferentially with the center of the supporting sleeve as the center, and each guiding wheel is fixedly connected with the lower end surface of the supporting sleeve.

[0042] Please refer to Figure 3 and Figure 4To ensure guidance of the support sleeve 2 during rotation, the system also includes guide wheels 8 evenly distributed on the lower end face of the support sleeve 2 and guide grooves 10 adapted to the guide wheels 8 on the upper end face of the fixed base 1. The guide grooves 10 are circumferentially arranged with the center of the support sleeve 2 as the center point. Each guide wheel 8 is fixedly connected to the lower end face of the support sleeve 2. This is achieved by evenly distributing the guide wheels 8 on their lower end face and providing guide grooves 10 adapted to the guide wheels 8 on the upper end face of the fixed base 1. The guide grooves 10 are evenly distributed circumferentially with the center of the support sleeve 2 as the center point. Thus, each guide wheel 8 can both support the anti-collapse agent container through its fixed connection to the lower end face of the support sleeve 2 and reduce friction and lateral movement during rotation by rolling within the guide grooves 10, thereby ensuring the stability and smoothness of the support sleeve 2 during rotation.

[0043] The implementation principle of the mixing equipment for anti-collapse agent for drilling fluid in this application embodiment is as follows: When the anti-collapse agent container is placed inside the limiting plate 3, pressure is applied to its outer periphery, causing the adjusting spring 31 to automatically contract under the pressure of the limiting plate 3. Thus, the limiting plate 3 effectively clamps and fixes anti-collapse agent containers of different sizes. In this process, one end of the adjusting spring 31 is fixedly connected to the outer side of the limiting plate 3, and the other end is fixedly connected to the inner wall of the support sleeve 2, so that it can automatically adjust according to the size change of the container during the placement and movement of the container, ensuring the flexibility and adaptability of the equipment.

The rotating disc 5 is connected with the first rotating shaft 50, and when the driving motor 74 is started, the rotating disc 5 is driven to rotate through the first rotating shaft 50. The end of the stirring rod 4 away from the support sleeve 2 is provided with a sliding seat 51, and when rotating, the sliding seat 51 rotates in the mounting seat 511 arranged on the support frame 100. The centrifugal motion of the stirring rod 4 is guided by the sliding seat 51, and with the continuous rotation of the rotating disc 5, the stirring rod 4 is subjected to centrifugal motion, thereby being capable of stirring the anti-collapse agent to different depths, achieving the effect of uniform distribution, effectively preventing local accumulation or settlement of the anti-collapse agent. The driving assembly drives the first belt pulley 71 to rotate through the first rotating shaft 50, the first belt pulley 71 drives the second belt pulley 72 to rotate through the transmission belt 73, and then the second rotating shaft 6111 is driven to rotate through the second belt pulley 72. The end of the second rotating shaft 6111 is engaged with the bevel gear ring 61, so that the rotation of the second rotating shaft 6111 drives the bevel gear ring 61 to rotate, thereby driving the support sleeve 2 fixed to the middle and lower part of the outer periphery of the support sleeve 2 to rotate, thereby realizing efficient stirring of the anti-collapse agent. In this process, the lower end surface of the support sleeve 2 is supported by the guide wheel 8 fixedly connected thereto, thereby maintaining the stability of the container. Secondly, the guide wheel 8 is rolled in the guide groove 10 to realize accurate guidance of the support sleeve 2, reduce vibration and deviation, and ensure the stability of the rotating support sleeve 2.
