[0029] In this embodiment, the shape of the auger seat 1 is "V"-shaped, and mounting holes are symmetrically opened inside the bottom end of the auger seat 1, so that the auger seat 1 can be conveniently fixed on the position of the fracturing sand mixing vehicle through the mounting holes.

[0030] In this embodiment, the driving mechanism includes a servo motor 11, and the servo motor 11 is fixedly mounted on the side wall of the auger seat 1. A screw 12 is fixedly arranged on the output shaft of the servo motor 11. The screw 12 is limitedly rotated and mounted inside the adjustment slot 10. The adjustment plate 13 is screwed on the screw 12 through a screw hole. The servo motor 11 drives the screw 12 to rotate, and the screw 12 screws and drives the adjustment plate 13 to rise and fall and slide inside the adjustment slot 10, so that the movable plate 9 can be driven to rise and fall and slide through the adjustment plate 13, thereby facilitating the subsequent lifting and lowering adjustment of the auger body 3.

[0031] In this embodiment, first balls 8 are symmetrically arranged on both sides of the surface of the bottom end of the movable plate 9, and the first balls 8 are arranged in an arc shape. Fixed blocks 7 are fixedly arranged at the bottoms of the two auger bodies 3 corresponding to the positions of the first balls 8. An arc groove is provided at the bottom of the fixed block 7, and the first balls 8 are arranged inside the arc groove.

[0034] When the sand conveying auger guide device of the fracturing sand mixing vehicle is used, the device is installed at the rear position of the fracturing sand mixing vehicle through the auger seat 1 and the fixing hole. The auger body 3 is movably installed on the top of the movable plate 9 through the fixing seat 14 and the shaft rod 16. Under the action of the fixing plate 19, the slide groove 20, the slider 18 and the wedge block 17, the auger body 3 can be limited so that the auger body 3 cannot rotate automatically. When sand needs to be conveyed, the servo motor 11 is started, and the servo motor 11 drives the screw rod 12 to rotate inside the adjusting groove 10. The screw 12 is screwed to drive the adjusting plate 13 to slide downward inside the adjusting groove 10. The adjusting plate 13 drives the movable plate 9 to slide on the top of the adjusting groove 10. At the same time, the movable plate 9 drives the auger body 3 to move downward through the shaft rod 16 and the fixing seat 14, and the auger body 3 drives the fixed plate 19 to move downward at the same time. A slope is provided on one side of the fixed plate 19. The fixed plate 19 is squeezed mutually between the slope and the wedge block 17, so that the fixed plate 19 drives the auger body 3 rotates to both sides with the shaft 16 as the axis, so that the bottom ends of the two auger bodies 3 are separated from each other, and the second ball 15 rolls between the movable plate 9 and the fixed seat 14, reducing the friction between the movable plate 9 and the fixed seat 14, making the auger body 3 rotate more smoothly; at the same time, the auger body 3 drives the fixed block 7 to rotate, and the first ball 8 rolls in the arc groove. Through the first ball 8, the arc groove and the fixed block 7, the auger body 3 can be supported and the friction between it and the movable plate 9 is reduced, avoiding the situation that the auger body 3 is difficult to rotate, and it is convenient to use; when folding, the servo motor 11 and the screw 12 are controlled to rotate in the opposite direction, and the servo motor 11 and the screw 12 drive the adjusting plate 13 to move upward, and the adjusting plate 13 drives the auger body 3 to move upward through the movable plate 9, the shaft 16 and the second ball 15. At the same time, under the limiting action of the slider 18 and the slide groove 20, the auger body 3 rotates in the opposite direction through the shaft 16, and the two auger bodies 3 are close to each other and merged.
