DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4The utility model provides a technical solution: a vehicle-mounted sand screening device, comprising a first screen 1 and a second screen 2, the first screen 1 and the second screen 2 are symmetrically arranged in an inverted V shape, and the first screen 1 and the second screen 2 are rotatably connected at the top, the first screen 1 and the second screen 2 are fixedly connected with a fixing rope 3, a vibrator 4 is fixedly installed on the inner side of the upper part of the first screen 1, and the bottoms of the first screen 1 and the second screen 2 are respectively rotatably connected with a fixing seat 5, and a buckle 52 is fixedly arranged below the fixing seat 5.

[0022] A first sleeve 11 is provided on the top of the first screen 1, and a second sleeve 21 is provided on the top of the second screen 2. A sleeve rod 12 is sleeved in the first sleeve 11, and one end of the sleeve rod 12 is sleeved in the second sleeve 21. Through holes are provided on the first sleeve 11 and the second sleeve 21, and threaded holes corresponding to the through holes are provided on the sleeve rod 12. The first sleeve 11, the second sleeve 21 and the sleeve rod 12 are fixedly connected by bolts inserted in the through holes and the threaded holes. In this connection mode, the first screen 1 and the second screen 2 are connected. When assembling the second screen 2, it is only necessary to remove the bolts on the sleeve rod 12, retract the sleeve rod 12 into the first sleeve tube 11 for a section and then dock it with the top of the second screen 2, then move the retracted part of the sleeve rod 12 out and insert it into the second sleeve tube 21, and re-tighten the bolts on the sleeve rod 12 to complete the connection between the first screen 1 and the second screen 2, which is convenient for assembly; a rotating shaft 51 is fixedly provided on the top of the fixing seat 5, and a hollow tube 13 is provided at the bottom of the first screen 1 and the second screen 2, and the hollow tube 13 is sleeved on the rotating shaft 51.

[0023] A transverse adjustment mechanism 6 is provided on the fixed seat 5, and the adjustment mechanism 6 includes an adjusting screw 61 and a threaded sleeve 62.
