A detachable pressing support 17 is installed on the side of the hydraulic push rod 16 in contact with the ton bag.

[0030] See Figure 6 , the pressing bracket 17 includes a pressing fixed seat 172, and a trapezoidal pressing frame 171 is arranged on the pressing fixed seat 172. The trapezoidal pressing frame 171 is in surface contact with the ton bag, which not only does not easily cut the ton bag, but also realizes the extrusion of the ton bag, making the materials in the ton bag loose. The pressing bracket 17 can be detachably installed at the top of the hydraulic push rod 16 by means of threaded connection, or other detachable connection methods can also be used.

[0031] See Figure 3 and Figure 4 , the expanding mechanism includes a support ring seat 24, and the support ring seat 24 is located at the top of the feeding port 22.

[0032] A plurality of arc-shaped grooves 23 are arranged on the inner side wall of the support ring seat 24. Preferably, the arc-shaped grooves 23 are equally angularly distributed on the inner side wall of the support ring seat 24.

[0033] A rotatable support arm 10 is arranged in each arc-shaped groove 23. One end of the support arm 10 is rotatably connected in the arc-shaped groove 23 and a strut 11 is arranged at the other end. Under the rotation of the support arm 10, the strut 11 opens the bag mouth of the ton bag placed between multiple outer protection plates 15, accelerating the feeding.

[0034] In order to adapt to the arc-shaped groove 23, the support arm 10 is also of an arc-shaped structure. At the same time, in order to prevent materials from falling on the support arm 10, a plurality of through holes 25 are arranged on the support arm 10.

[0035] A transmission shaft 8 is arranged in each arc-shaped groove 23. A limiting block 9 is connected to one end of the support arm 10 located in the arc-shaped groove 23, and the limiting block 9 is fixedly connected to the bottom of the transmission shaft 8. A driven gear 7 is installed on the transmission shaft 8, and the driven gear 7 is meshed with a transmission ring 4.

[0036] In order to make the meshing connection between the multiple driven gears 7 and the transmission ring 4 more stable, the transmission ring 4 is arranged flush with the tabletop of the support seat 1. A plurality of clamping blocks 12 are arranged between the transmission ring 4 and the tabletop of the support seat 1. An auxiliary wheel 13 is arranged inside each clamping block 12 for assisting and pressing the transmission ring 4, which can not only ensure the stable rotation of the transmission ring 4, but also limit the up and down position of the transmission ring 4 to avoid up and down movement and affect the stability of the transmission.

[0037] See Figure 2 , a conical material blocking plate 14 is arranged above the expanding mechanism to prevent material leakage. Specifically, the material blocking plate 14 is arranged along the inner side wall of the support ring seat 24.

[0038] See Figure 3 andFigure 5 The drive ring 4 is arranged outside the support ring seat 24. A plurality of second tooth grooves 6 are arranged on the inner side wall of the drive ring 4, and a plurality of first tooth grooves 5 are arranged on the outer side wall of the drive ring 4. The second tooth grooves 6 are meshed and connected with the driven gear 7, the first tooth grooves 5 are meshed and connected with a driving gear 3, the driving gear 3 is connected to the output end of the first motor 2, and the first motor 2 is fixedly installed inside the support seat 1.

[0039] The opening size of the big bag mouth is controlled by the rotation angle of the support rod 11 on the support arm 10. The first motor 2 can be controlled through a control program of the prior art, so as to realize the control of the rotation angle of the support arm 10. Therefore, the opening size of the big bag mouth can be controlled according to actual requirements.

[0040] After the big bag is fed, in order to further disperse the materials, a dispersing mechanism is arranged below the expanding mechanism. See Figure 1 and Figure 7 The dispersing mechanism includes a second motor 18, and the second motor 18 is arranged on the front side of the support seat 1. The output end of the second motor 18 is fixedly connected with a rotating shaft 19, the rotating shaft 19 passes through the feeding port 22, and the other end of the rotating shaft 19 is fixedly connected to the inner wall of the feeding port 22 through a positioning block 21. A dispersing rod 20 is arranged on the rotating shaft 19. The second motor 18 drives the rotating shaft 19 and the two dispersing rods 20 to disperse the materials inside the support seat 1, so that the materials can quickly fall from the inside of the support seat 1.

[0041] When feeding the big bag, first, the crane hoists the big bag above the support seat 1 and puts the bag mouth of the big bag into the inside of the plurality of outer guard plates 15. When the bag mouth of the big bag contacts the plurality of support rods 11, the support rods 11 are inserted into the bag mouth of the big bag under the action of the gravity of the big bag. Then, the first motor 2 is started to drive the driving gear 3 to rotate. The driving gear 3 meshes with the first tooth grooves 5 on the outside of the drive ring 4, so as to drive the drive ring 4 to rotate smoothly with the assistance of the clamping blocks 12 and the auxiliary wheels 13. The drive ring 4 is in meshing transmission with the plurality of driven gears 7 through the second tooth grooves 6 on the inner side wall. Each driven gear 7 drives the corresponding transmission shaft 8 and the limit block 9 to rotate. The limit block 9 drives the corresponding support arm 10 and the support rod 11 to open inside the support seat 1 to expand the bag mouth of the big bag, so that the materials in the big bag can be discharged through the support seat 1. At the same time, the second motor 18 drives the rotating shaft 19 and the dispersing rod 20 to disperse the falling materials, so that the materials can quickly fall. Finally, the hydraulic push rods 16 on the four outer guard plates 15 drive the pressing bracket 17 to push, and extrude the outside of the big bag, so that the materials inside the big bag can be kept in a loose state for easy feeding, and the materials inside the big bag are fed through the support seat 1.

[0042] The utility model provides an auxiliary device for ton bag feeding. Through an expansion mechanism, it assists in opening the bag mouth of the ton bag, and the opening size of the bag mouth can be controlled according to actual needs to ensure the smoothness of feeding. Through an auxiliary feeding mechanism, it not only fixes the ton bag, but also can squeeze the ton bag to make the materials in the ton bag loose, avoid blockage of the materials at the discharge port, and improve the feeding efficiency of the ton bag.

[0043] Certainly, the utility model can also have many other embodiments. Without departing from the spirit and essence of the utility model, those skilled in the art can make various corresponding changes and deformations according to the utility model. However, these corresponding changes and deformations should all fall within the protection scope of the appended claims of the utility model.
