DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0023] like Figure 1 to Figure 5 As shown, a quartz sand filling device comprises a filling hopper 1, which is connected to a feeding pipe 2; and also comprises a bag-supporting member arranged on the feeding pipe 2, the bag-supporting member comprises a bearing plate 3, a driving ring 4 and a bag-supporting assembly; the bearing plate 3 is a circular plate body, the bearing plate 3 is sleeved and fixed on the outside of the feeding pipe 2 through a circular hole 11 opened in the middle, the feeding pipe 2 on the upper side of the bearing plate 3 is slidably sleeved with a driving ring 4 up and down, the driving ring 4 is a circular ring plate, the bearing plate 3 is provided with a bag-supporting assembly in an annular array, the bag-supporting assembly comprises a blind hole 5, a slider 6 and a vertical rod 7, the blind hole 5 is recessed from the circumference of the bearing plate 3 to the center of the bearing plate 3, The blind hole 5 is a rectangular hole, the opening of the blind hole 5 is blocked by a sealing plate 8, a slider 6 is slidably provided in the blind hole 5, the slider 6 is a rectangular block that slides in contact with the blind hole 5, one end of the slider 6 and the side of the blind hole 5 facing the center of the bearing plate 3 are connected with an elastic belt 9, the other end of the slider 6 is connected with a steel strand 10, the free end of the steel strand 10 movably passes through the sealing plate 8 at the opening of the blind hole 5 and is connected to the outer ring surface of the driving ring 4, the bottom surface of the bearing plate 3 is provided with a sliding hole 12 connected to the blind hole 5, the sliding hole 12 is a long strip hole opened along the length direction of the blind hole 5, and the vertical rod 7 passes through the sliding hole 12 to connect to the bottom surface of the slider 6.

[0024] The driving ring 4 is driven by the hydraulic cylinder 13 to move upward or downward; the hydraulic cylinder 13 is fixed to the top surface of the bearing plate 3, and the piston end is connected to the bottom surface of the driving ring 4 facing upward.

[0025] The bottom surface of the bearing plate 3 is flush with the lower end of the feeding pipe 2, and the sealing plate 8 is provided with a through hole 14 for the steel strand 10 to pass through.

[0026] The vertical rod 7 is a round rod, and an anti-slip pattern 15 is arranged on the peripheral wall of the vertical rod 7 .

[0027] The width of the sliding hole 12 is smaller than the width of the blind hole 5 , and the width of the sliding hole 12 is larger than the diameter of the vertical rod 7 .

[0028] The elastic belt 9 is a long strip made of elastic rubber; when the driving ring 4 drops to the limit state, the elastic belt 9 on each bag support assembly is in a natural state, and the slider 6 connected to the elastic belt 9 is close to the side of the blind hole 5 facing the center of the supporting plate 3.

[0029] In the initial state, the driving ring 4 is lowered to the limit state, at which time the elastic band 9 on each bag support assembly is in a natural state, and the slider 6 connected to the elastic band 9 is close to the side of the blind hole 5 facing the center of the carrier plate 3;

[0030] When in use, the bag body carrying quartz sand is opened and put outside the multiple vertical rods 7, and the piston end of the hydraulic cylinder 13 drives the driving ring 4 to move upward. When the driving ring 4 moves upward, the multiple steel strands 10 connected to one end of the driving ring 4 move upward with the driving ring 4. The steel strands 10 are connected to one end of the slider 6, which pulls the slider 6 toward the open end of the blind hole 5. The elastic band 9 connected to the slider 6 is stretched, and the vertical rods 7 connected to the slider 6 move with the slider 6. Therefore, in the process of the driving ring 4 moving upward, the diameter of the ring where the multiple vertical rods 7 are located gradually increases as the driving ring 4 moves upward, until the multiple vertical rods 7 hold the bag body tightly. At this time , the bag body is limited and fixed, and the anti-slip patterns 15 on the vertical pole 7 can strengthen the connection between the bag body and the vertical pole 7. After the bag body is limited and fixed, the hydraulic cylinder 13 stops working, and the filling bucket 1 can fill the quartz sand into the bag body through the discharge pipe 2; after the quartz sand in the bag body is filled, the discharge pipe 2 stops discharging, and the piston end of the hydraulic cylinder 13 drives the driving ring 4 to move downward, and under the restoring force of the elastic band 9 of each bag support component, the connected slider 6 is driven back to the initial position, each steel strand 10 returns to the initial position, and multiple vertical poles 7 return to the initial position, and the bag body is no longer limited, so the bag body and the bag support component can be conveniently separated.

[0031] The preferred implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings; however, the present invention is not limited to the above-mentioned embodiments. Without violating the spirit of the present invention, i.e., the disclosure scope, any equivalent or equivalent deformation or replacement of the technical solution of the present invention shall fall within the protection scope of the present invention.
