Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction equipment technology, specifically a cement feeding hopper. Background Technology
[0002] Cement refers to a powdered hydraulic inorganic binder that, when mixed with water to form a paste, hardens in air or water. It is used to bind loose materials such as sand and stone into mortar or concrete. Any hydraulic binder that is finely ground into powder, and when mixed with an appropriate amount of water, becomes a plastic paste that hardens both in air and water, and can firmly bind materials such as sand and stone together, is generally called cement.
[0003] Cement hoppers are common containers for conveying cement in construction. They facilitate the convenient transport of cement through hoisting and conveying. However, in actual use, they have the following shortcomings: First, cement slurry may remain and solidify inside the hopper during the cement transport process, increasing the hopper's weight and gradually reducing its capacity, thus affecting the cement transport efficiency and increasing the hoisting pressure. Second, existing hoppers do not allow for convenient control of the cement flow rate, leading to difficulties in discharging cement during the process. Therefore, a new cement hopper needs to be designed to address these issues. Utility Model Content

In addition, existing hoppers do not allow for convenient control of cement flow rate during use, leading to inconvenience in cement discharge during the process.

[0023] This utility model provides a technical solution for a cement feeding hopper:
[0024] Please see Figures 1-5 A cement hopper includes an end plate 1, a hopper 2 fixedly connected to one side of the end plate 1, a plurality of circumferentially arranged support rods 3 fixedly connected to one side of the end plate 1, a contact frame 4 fixedly connected to the end of the plurality of support rods 3 away from the end plate 1, a discharge pipe 10 fixedly connected to one side of the hopper 2, an inner pipe 6 provided inside the hopper 2, a lifting mechanism for lifting the inner pipe 6 provided inside the inner pipe 6, a rotating shaft 9 rotatably connected inside the discharge pipe 10, a rotating frame 14 fixedly connected to the side wall of the rotating shaft 9, a control mechanism for controlling the cement flow rate provided on the side wall of the rotating shaft 9, and a drive mechanism for driving the cement flow rate control on the side wall of the discharge pipe 10.
[0025] Furthermore, the lifting mechanism includes multiple circumferentially arranged connecting ears 7 fixedly connected to the inner wall of the inner tube 6, and multiple circumferentially arranged lifting ears 5 fixedly connected to the side of the end plate 1 away from the hopper 2. Lifting holes are opened on one side of both the connecting ears 7 and the lifting ears 5.
[0026] Furthermore, the control mechanism includes a movable frame 13 sleeved on the side wall of the rotating shaft 9, and multiple circumferentially arranged discharge troughs 18 are provided on one side of both the movable frame 13 and the rotating frame 14.
[0027] Furthermore, the side wall of the movable frame 13 is fixedly connected with a plurality of circumferentially arranged limiting blocks 16, the inner wall of the discharge pipe 10 is provided with a plurality of circumferentially arranged limiting grooves 15, the limiting blocks 16 are slidably connected in the limiting grooves 15, the side wall of the rotating shaft 9 is provided with external threads 17, and the movable frame 13 is threadedly connected to the external threads 17.
[0028] Furthermore, the drive mechanism includes a drive box 11 fixedly connected to one side of the discharge pipe 10, a drive shaft 19 rotatably connected inside the drive box 11, a drive gear 20 fixedly connected to the side wall of the drive shaft 19, a drive tooth fixedly connected to the side wall of the rotating frame 14, the drive gear 20 meshing with the drive tooth, a motor 12 fixedly connected inside the drive box 11, and the output shaft of the motor 12 fixedly connected to the drive shaft 19.
[0029] Furthermore, a screw conveyor blade 21 is fixedly connected to the side wall of the rotating shaft 9, and a support frame 8 is fixedly connected to the side wall of the inner tube 6. The support frame 8 is sleeved on the side wall of the rotating shaft 9.
[0030] In practical use, the working principle of this utility model is as follows:
[0031] In use, the inner tube 6 is first placed inside the hopper 2 and kept in a fitted state. At this time, the support frame 8 is sleeved on the side wall of the rotating shaft 9, providing rotational support for the upper end of the rotating shaft 9. During transportation, the hopper 2 is hoisted and transported as a whole by the lifting lug 5. After the cement is discharged, the inner tube 6 is separated from the hopper 2 by pulling multiple connecting lugs 7. The hopper 2 is cleaned by cleaning the residual cement in the inner tube 6. After cleaning, the inner tube 6 is put back into the hopper 2, so that the hopper 2 can be reused. During the discharge process, the motor 12 drives the rotation of the transmission shaft 19, which can drive the relative rotation of the moving frame 13 and the rotating frame 14. At this time, the discharge chute 18 on the rotating frame 14 and the moving frame 13 moves relative to each other. The discharge amount and discharge speed of cement in the hopper 2 can be controlled by the size of the connection state.
[0032] During this process, the external thread 17 on the rotating shaft 9 is threadedly connected to the rotating frame 14 through the sliding limit of the limiting block 16 and the limiting groove 15, which can drive the rotating frame 14 to move downward. When the rotating frame 14 is disengaged from the discharge pipe 10, the hopper 2 is at its maximum discharge capacity and speed. During this process, the motor 12 drives the rotation of the transmission shaft 19 and drives the rotation of the drive gear 20 to mesh with the drive teeth on the side wall of the moving frame 13. While driving the moving frame 13 to rotate, it can drive the rotation of the rotating shaft 9. At this time, the auger blades 21 on the side wall of the rotating shaft 9 rotate and contact the cement in the inner tube 6, and convey it by the spiral feeding method to avoid the problem of raw material blockage.
[0033] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
