The transverse grooves 14 are interconnected, and the outer surface of the nut seat 8 is fixedly connected with a moving column 5, and the moving column 5 extends out of the lower transverse groove 14, and the moving column 5 is slidably connected to the lower transverse groove 14. The outer surface of the fixed ascending cylinder 2 is slidingly sleeved with a slide cylinder 3, and the moving column 5 is fixedly connected to the slide cylinder 3. The outer surface of the slide cylinder 3 is fixedly connected with a hopper 4, and the lower end of the screw 7 rotates and passes through the outer surface of the base frame 1. The lower end of the screw 7 is fixedly sleeved with a worm gear 12, and the outer surface of the base frame 1 is fixedly connected with a motor fixing plate 9, and a motor 10 is fixedly connected to the motor fixing plate 9. The outer surface of the output shaft of the motor 10 is fixedly sleeved with a worm 11, and the worm 11 is meshingly connected with the worm gear 12.

[0024] Furthermore, when in use, the material to be lifted is placed in the hopper 4, and then the motor 10 is started. The output shaft of the motor 10 will drive the worm 11 thereon to rotate. When the worm 11 rotates, it will drive the worm wheel 12 to rotate through the spiral groove thereon. When the worm wheel 12 rotates, it will drive the screw 7 to rotate at the same time. The rotating screw 7 will first drive the moving column 5 to rotate with the axis of the screw 7 as the center through the nut seat 8. The rotating moving column 5 will drive the hopper 4 thereon to rotate together through the slide cylinder 3 until the moving column 5 rotates into the vertical slot 6, the moving column 5 contacts the right wall of the vertical slot 6, and then the screw 7 that continues to rotate The screw thread thereon will drive the screw rod 7 and the moving column 5 to move upward in the opposite direction along the axis of the vertical slot 6 until the moving column 5 moves to the upper end of the vertical slot 6. At this time, the moving column 5 is out of the restriction of the vertical slot 6. Under the action of the continuous rotation of the screw rod 7, the moving column 5 returns to the upper horizontal slot 13. At this time, the hopper 4 has rotated 180° and lifted upward to a specified height. Through the operation of the above structure, the material in the hopper 4 can be rotated a certain angle before being lifted upward, avoiding the problem that most of the traditional elevators rise in a straight trajectory and it is difficult to effectively lift the material when the space is limited.

[0025] Furthermore, the self-locking property of the worm 11 and the worm wheel 12 can ensure that when the hopper 4 rises to any height and the power is suddenly cut off, the hopper 4 will be fixed at the current position and will not fall suddenly, which improves the operating stability of the elevator to a certain extent and avoids the occurrence of dangerous situations.

[0026] Working principle: When in use, the material to be lifted is placed in the hopper 4, and then the motor 10 is started. The output shaft of the motor 10 will drive the worm 11 thereon to rotate. When the worm 11 rotates, it will drive the worm wheel 12 to rotate through the spiral groove thereon. When the worm wheel 12 rotates, it will drive the screw 7 to rotate at the same time. The rotating screw 7 will first drive the moving column 5 to rotate with the axis of the screw 7 as the center through the nut seat 8. The rotating moving column 5 will drive the hopper 4 thereon to rotate together through the slide cylinder 3 until the moving column 5 rotates into the vertical slot 6, and the moving column 5 contacts the right wall of the vertical slot 6, and then the screw 7 that continues to rotate The screw thread thereon will drive the screw rod 7 and the moving column 5 to move upward in the opposite direction along the axis of the vertical slot 6 until the moving column 5 moves to the upper end of the vertical slot 6. At this time, the moving column 5 is out of the restriction of the vertical slot 6. Under the action of the continuous rotation of the screw rod 7, the moving column 5 returns to the upper horizontal slot 13. At this time, the hopper 4 has rotated 180° and lifted upward to a specified height. Through the operation of the above structure, the material in the hopper 4 can be rotated a certain angle before being lifted upward, avoiding the problem that most of the traditional elevators rise in a straight trajectory and it is difficult to effectively lift the material when the space is limited.

[0027] Furthermore, the self-locking property of the worm 11 and the worm wheel 12 can ensure that when the hopper 4 rises to any height and the power is suddenly cut off, the hopper 4 will be fixed at the current position and will not fall suddenly, which improves the operating stability of the elevator to a certain extent and avoids the occurrence of dangerous situations.
