[0031] The flow dividing device includes a dividing cylinder 12, which is fixedly mounted on the top wall of the vibrating screen 10. A second screen 19 for separating large and small stones is arranged in the cavity of the dividing cylinder 12, and two partitions 24 are arranged in the cavity of the vibrating screen 10.
[0032] In actual use, when the staff pours the drilling fluid into the cavity of the separation cylinder 12, the second screen 19 can screen the stones of different sizes, and then pour the drilling fluid into the cavity of the vibrating screen 10, so that the partition 24 cooperates with the first screen 11 to screen the drilling fluid and stones in sections.
[0033] In summary, by setting up the diversion device, the first screen 11, the dividing cylinder 12, the second screen 19, the partition 24 and the vibrating screen 10, the stones of different sizes in the drilling fluid can be separated first, and then the drilling fluid is vibrated and screened through the first screen 11 to separate the drilling fluid from the stones. Compared with the existing technology, it is easy to use and has a simple structure.
[0034] like Figure 2 and Figure 5 As shown, three first connecting holes 13 are opened at equal intervals on the bottom wall of the separating cylinder 12, and three second connecting holes 25 are opened at equal intervals on the top wall of the vibrating screen 10. The first connecting holes 13 and the first guide plate 15 connect the separating cylinder 12 with the cavity of the vibrating screen 10.
[0035] The two partitions 24 are fixedly mounted on the top wall of the cavity of the vibrating screen 10 , the bottom walls of the two partitions 24 are in contact with the top wall of the first screen 11 , and the positions of the two partitions 24 correspond to the positions between two adjacent first connecting holes 13 .
[0036] During specific use, when the staff pours the drilling fluid into the cavity of the separating cylinder 12, the second screen 19 will first separate the stones in the drilling fluid, and then inject it into the cavity of the vibrating screen 10 through the first connecting hole 13 and the second connecting hole 25 at different positions. Then the partition 24 can separate the different drilling fluids, so that the first screen 11 can perform screening operations, so that larger stones will not affect the screening of smaller stones, and smaller stones will not affect the movement of larger stones.
[0037] In summary, by setting the distinguishing cylinder 12, the first connecting hole 13, the second connecting hole 25, the partition 24, the vibrating screen 10 and the first screen 11, stones of different sizes can be distinguished so that larger stones will not affect the movement of smaller stones, and smaller stones will not affect the screening of larger stones, thereby improving the screening efficiency of drilling fluid and stones. It is easy to use and has a simple structure.

The drive motor 21 is connected to the power supply and the switch by electrical signals.
[0041] During specific use, the staff can pour the drilling fluid into the cavity of the dividing cylinder 12 through the driving motor 21 and the first guide plate 15, and then rotate the driving motor 21 to rotate the connecting plate 16. The rotation of the connecting plate 16 can drive the connecting block 18 to rotate, and the rotation of the connecting block 18 can drive the diverter cylinder 20 to rotate. The rotation of the diverter cylinder 20 can drive the second screen 19 to rotate. The rotation of the second screen 19 can improve the efficiency of differentiation. The drilling fluid with smaller stones can be directly screened by the vibrating screen 10 and flow downward, and flow into the cavity of the vibrating screen 10 from the first connecting hole 13 away from the middle side. The left and right sides of the cavity of the second screen 19, the drilling fluid with larger stones will be added to the cavity of the middle first connecting hole 13 through the cavity of the diverter cylinder 20 and flow into the position between the vibrating screen 10, so that the drilling fluid with different stone sizes can be segmented and screened, so as to improve the screening efficiency.
