[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0021] Figure 1-4 The components include: bag support mounting base 1, material feeding and bag clamping valve 2, synchronizing rod 3, bag support rod 4, first connecting rib plate 5, second connecting rib plate 6, lower bucket body 7, upper bucket body 8, bearing 9, bag clamping bucket fixing plate 10, bag clamping bucket shell assembly 11, bag clamping bucket flange plate 11-1, hopper plate 11-2, bag clamping bucket outer shell plate 11-3, guide plate 11-4, mounting plate 11-5, bag support cylinder 12, first support shaft 13, bag clamping cylinder 14, bag clamping connecting rod 15, bag clamping pressure plate 16, etc.

[0022] like Figure 1-4 As shown, this utility model is a bag clamping bucket structure, including an upper bucket body 8. The upper end of the upper bucket body 8 is constructed as a connecting flange surface. The lower part of the upper bucket body 8 is rotatably connected to a lower bucket body 7. The lower end of the lower bucket body 7 is fixedly connected to a bag clamping bucket shell assembly 11. A feeding bag clamping valve 2 is rotatably connected to each side of the bag clamping bucket shell assembly 11. The upper end of the feeding bag clamping valve 2 cooperates with the feeding end of the bag clamping bucket shell assembly 11 to receive feeding. The two feeding bag clamping valves 2 are synchronously opened and closed during operation through a synchronization component.

[0023] The upper part of the bag clamping valve 2 is hinged to a bag clamping cylinder 14, and the lower part is hinged to a bag clamping connecting rod 15. The piston rod of the bag clamping cylinder 14 is hinged to the bag clamping connecting rod 15. A bag clamping pressure plate 16 is installed on the bag clamping connecting rod 15. The bag clamping pressure plate 16 can press the bag tightly against the side plate of the bag clamping valve 2. A triangular plate is vertically installed on each side of the side plate of the bag clamping valve 2 in the width direction.

[0024] A bag-supporting assembly is installed on the bag-holding housing assembly 11 to open the bag.

[0025] The upper bucket 8 has an arc-shaped guide section, and the upper end of the lower bucket 7 covers the surface of the upper bucket 8. The lower bucket 7 can rotate and adjust along the arc-shaped guide section of the upper bucket 8.

[0026] The upper bucket body 8 is provided with a first support shaft 13, and the two ends of the first support shaft 13 are rotatably supported on the bearings 9 on the lower bucket body 7.

[0027] The bag clamping hopper shell assembly 11 includes a bag clamping hopper flange plate 11-1. A hopper plate 11-2 is fixed to each side of the bottom surface of the flange plate 11-1. A bag clamping hopper outer shell plate 11-3 is fixed to the outer side of each hopper plate 11-2. A guide plate 11-4 is provided on the bottom surface of the flange plate 11-1 between the two hopper plates 11-2. A mounting plate 11-5 is provided on the outer side of each hopper plate 11-2 for rotatably connecting the discharge bag clamping valve 2. When both discharge bag clamping valves 2 are closed, the triangular plate of the discharge bag clamping valve 2 extends between the hopper plate 11-2 and the bag clamping hopper outer shell plate 11-3. The hopper plate 11-2 is constructed in the shape of an isosceles triangle. The triangular plates on both sides of the discharge bag clamp valve 2 cover the outer side of the hopper plate 11-2, forming a discharge space. When the discharge bag clamp valve 2 is closed, the side plates of the discharge bag clamp valve 2 are attached to the side of the hopper plate 11-2. The outer shell plate 11-3 of the bag clamp hopper extends vertically to the lower end of the hopper plate 11-2 to cooperate with the discharge bag clamp valve 2 and the hopper plate 11-2 to form a closed discharge valve frame.

[0028] The synchronization component includes a synchronization rod 3, one end of which is connected to a first connecting rib 5, and the other end to a second connecting rib 6. The first connecting rib 5 is fixedly connected to the rotating shaft of one of the discharge bag clamping valves 2, and the second connecting rib 6 is fixedly connected to the rotating shaft of the other discharge bag clamping valve. A bearing is installed at each end of the rotating shaft of each of the two discharge bag clamping valves 2, and the corresponding bearings are respectively limited to the mounting plate 11-5 of the bag clamping hopper housing assembly 11 by a bag clamping hopper fixing plate 10. It can be understood that, in order to achieve synchronous operation of the two discharge bag clamping valves 2, the two ends of the synchronization rod 3 are respectively constructed with a cross-section that combines an arc and a straight line. Simultaneously, the inner holes of both the first connecting rib 5 and the second connecting rib 6 are also constructed with a structure that combines an arc and a plane. Thus, when the first connecting rib 5 and the second connecting rib 6 are connected to the rotating shaft of the discharge bag clamping valve 2, synchronous operation of the two discharge bag clamping valves 2 can be achieved. The rotating shaft of the bag-feeding clamping valve 2 is welded to the surface of the outer shell plate 11-3 of the bag-feeding hopper, so that the rotating shaft drives the rotation of the bag-feeding clamping valve 2.

[0029] The bag support assembly includes a bag support mounting base 1, on which a bag support cylinder 12 is mounted. The piston rod of the bag support cylinder 12 is hinged to a bag support rod 4. The bag support rod 4 is sleeved on a second support shaft, which is fixed to the side of the bag clamping hopper housing assembly 11.

[0030] The lower end of the bag support rod 4 is bent inward.

[0031] like Figure 1-4As shown, during operation, the discharge bag clamping valve 2 rotates outward, causing it to flare outward. At this time, a bag is fitted onto the discharge bag clamping valve 2, and the bag clamping cylinder 14, via the bag clamping connecting rod 15, drives the bag clamping pressure plate 16 to clamp the bag onto the outer surface of the discharge bag clamping valve 2. It can be understood that at this time, the bag supporting cylinder 12 drives the bag supporting rod 4 to retract inward, fitting against the outer surface of the bag clamping hopper outer shell plate 11-3. After the bag is fitted, the discharge bag clamping valve 2 rotates to a vertical position to facilitate receiving the material from the upper hopper 8. At this time, the discharge bag clamping valve 2 opens, and the material in the upper hopper 8 falls through the lower hopper 7, falling from the outlet of the discharge bag clamping valve 2 into the bag. It can be understood that, to facilitate receiving the material, the bag supporting cylinder 12 drives the bag supporting rod 4 to open outward, thereby opening the bag outward to ensure that the material accurately falls into the bag and does not leak out.

[0032] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
