Specific implementation mode

[0022] The technical solutions in the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0024] In an exemplary embodiment, as Figures 1-3 shown, this embodiment provides a lifting mechanism for a blanking chute, which includes a feeding hopper 1. The opposite sides of the feeding hopper 1 are respectively fixedly connected with a first mounting plate 2 and a second mounting plate 3. The two first mounting plates 2 are located between the two second mounting plates 3. Reduction gears 4 are respectively detachably mounted on the opposite sides of the two second mounting plates 3, and the reduction gear 4 is also connected with a driving motor 5. The reduction gear 4 is provided with an output shaft 6. The output shaft 6 rotates through the second mounting plate 3 and the first mounting plate 2 adjacent to the reduction gear 4, and a mounting sleeve 7 is relatively fixedly sleeved outside the output shaft 6. Limiting rings 8 are respectively fixedly connected to both ends of the mounting sleeve 7.

[0025] In the above embodiments, a chute structure can be provided below the feed hopper 1. A steel cable 9 is wound around the mounting sleeve 7, and the steel cable 9 is connected to the lower end of the chute. Then, the mounting sleeve 7 can be rotated by driving the speed reducer 4 with a motor, so as to realize the lifting of the chute. Among them, the speed reducer 4 and the mounting sleeve 7 can be disassembled and assembled together with the feed hopper 1, and can also be conveniently detached from the feed hopper 1 for maintenance on the ground, reducing the maintenance difficulty and solving the problem that the lifting mechanism in the prior art is fixedly installed on the suspension bracket, which brings inconvenience to maintenance. Specifically, a reinforcing frame 10 is also fixedly connected to the outer upper end of the feed hopper 1. A pair of third mounting plates 11 are also fixedly connected between the reinforcing frame 10 and the feed hopper 1. And the second mounting plate 3 is connected to one of the third mounting plates 11 through a plurality of first bolts 12. The reinforcing frame 10 provides structural reinforcement for other components and also directly connects to the third mounting plate 11. The two can be integrally formed by welding, and the structure is more stable. While the second mounting plate 3 can be disconnected from the third mounting plate 11 by removing the first bolts 12, that is, it can be loosened from the main structure of the feed hopper 1. Further, the speed reducer 4 and the second mounting plate 3 are connected through a plurality of second bolts 13. In this way, the speed reducer 4 can be removed by removing the second bolts 13, and the driving motor 5 can also be disassembled together. More specifically, both ends of the mounting sleeve 7 extend beyond the two limit rings 8 and are respectively fixed to the output shaft 6 through pins 14. After removing the pins 14, the output shaft 6 can be released, and then the speed reducer 4 is pulled outwards, and the output shaft 6 can be pulled out between the first mounting plate 2 and the second mounting plate 3 to realize disassembly, which is convenient for subsequent specialized maintenance and is also relatively convenient for installation.

[0026] As Figures 1-3 shown, a reinforcing plate 15 (realized by welding) is also fixedly connected between the feed hopper 1 and the third mounting plate 11, and the reinforcing plate 15 is also fixedly connected to the reinforcing frame 10. The reinforcing plate 15 can play a role in strengthening the overall structure. At the same time, the first mounting plate 2 is fixedly connected to one of the reinforcing plates 15, and the reinforcing plate 15 provides a direct mounting foundation for the first mounting plate 2.

[0027] As Figures 1-3 shown, a first top ring 16 is also fixedly connected to the side of the first mounting plate 2 facing the adjacent second mounting plate 3. The first top ring 16 is separated from the end face of the adjacent mounting sleeve 7. Similarly, a second top ring 17 is also fixedly connected to the side of the second mounting plate 3 facing the adjacent first mounting plate 2. The second top ring 17 is separated from the end face of the adjacent mounting sleeve 7. In this way, the limit ring 8 on the mounting sleeve 7 can be relatively separated from the first mounting plate 2 or the second mounting plate 3, leaving a large disassembly and assembly space, and at the same time avoiding accidental sundries getting stuck in the gap.

[0028] As Figure 1 、 4As shown, similar to the prior art, in this solution, the steel cable 9 is also used to lift the chute below the feed hopper 1. The difference is that the steel cable 9 in this solution is wound around the mounting sleeve 7 and located between the two limit rings 8. The provided perforation 18 can allow one end of the steel cable 9 to pass through, and then by tying a knot or setting a limit block, etc., the steel cable 9 is prevented from disengaging from the limit ring 8.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
