When the weighing frame 3 moves in the vertical direction, the conical sleeve 5 and the fixed tube 21 can maintain a sealed connection, thereby preventing material overflow from affecting the working environment. At the same time, the setting of the fixed tube 21 and the conical sleeve 5 can facilitate the installation of the telescopic sleeve 6.

[0035] In some embodiments, the exhaust pipe 4 may be Figure 2 See the structure shown. Figure 2 The exhaust pipe 4 is fixedly mounted on the side wall of the fixed pipe 21 and is tilted upward away from the fixed pipe 21. One end of the exhaust pipe 4 is fixedly mounted on the side wall of the fixed pipe 21, and the other end extends upward and protrudes from the top of the weighing frame 3.

The flanges 311 are arranged on the upper and lower sides of the conical sleeve 5 and the feeding pipe 8 for being fixed to the reinforcing rib 31. A plurality of reinforcing ribs 31 are fixedly installed on the weighing frame 3, and the reinforcing ribs 31 are arranged in a square frame for installing the flanges 311 of the conical sleeve 5 and the feeding pipe 8. Preferably, the reinforcing rib 31 in the embodiment is processed from a U-shaped steel, and the two side plates of the U-shaped steel are arranged on the upper and lower sides of the reinforcing rib 31. The flange 311 is fixedly installed on the outer side of the conical sleeve 5 and is fixedly installed on the side plate on the upper side of the reinforcing rib 31 by bolts. The flange 311 is also fixedly installed on the outer side of the feeding pipe 8 and is fixedly installed on the side plate on the lower side of the reinforcing rib 31 by bolts. The reinforcing rib 31 can realize the fixation of the conical sleeve 5 and the feeding pipe 8 at the same time.

The fixed end of the driving member is hingedly provided on the mounting plate, and the driving end of the driving member is hingedly provided on the top of the hook, so that the hook can be driven to rotate and the hanging bag on the ton bag can be hung on the hook.

[0042] Specifically, in this embodiment, the structure of the hook adopts the existing technology, which will not be elaborated here. By providing a hanging component 71 that can adjust the position, it is suitable for ton bags with hanging bags of different lengths.

[0043] Specifically, in this embodiment, the clamping assembly 72 is used to clamp the feed port of the ton bag to the outer side wall of the feeding pipe 8, thereby achieving the connection between the ton bag and the feeding pipe 8.

[0044] In some embodiments, the clamping assembly 72 may be configured as follows: Figure 3 The structure shown. Figure 3 The clamping assembly 72 includes a clamping frame 721 and a pusher 722. There are two clamping frames 721, each hingedly mounted on the feeding tube 8 at its top end. The bottom ends of the two clamping frames 721 are used to clamp and secure the ton bag. The pusher 722 is installed between the two clamping frames 721. The fixed end of the pusher 722 is hingedly mounted in the middle of one of the clamping frames 721, and the driving end of the pusher 722 is hingedly mounted in the middle of the other clamping frame 721. The two clamping frames 721 are arranged parallel to each other at intervals on the feeding tube 8. The pusher 722 is a pneumatic cylinder, with its driving end and fixed end hingedly mounted on the two clamping frames 721. The pusher 722 can drive the two clamping frames 721 to rotate toward each other, clamping the ton bag's feed port between the two clamping frames 721.

[0045] In some embodiments, the clamping frame 721 may be configured as follows: Figure 3 The structure shown. Figure 3The two clamping frames 721 are each fixedly mounted with a first clamping block 723 and a second clamping block 724. The first clamping block 723 has a curved protrusion protruding from its support block, while the second clamping block 724 has a curved groove recessed into its side that corresponds to the curved protrusion. The clamping area for the ton bag is located between the curved protrusion and the groove. There are two first clamping blocks 723 and two second clamping blocks 724, each located on the same clamping frame 721. A clearance is provided between the two first clamping blocks 723 and the two second clamping blocks 724 to allow for the feeding pipe 8 to pass through. When the feed opening of the ton bag is inserted into the outside of the feeding tube 8 and its edge is clamped between the first clamping block 723 and the second clamping block 724, the feed opening of the ton bag is clamped between the arc-shaped protrusion and the arc-shaped groove, thereby further improving the stability of the ton bag clamping and ensuring the stability of the ton bag fixed between the two clamping frames 721.
