Description

Technical Field

[0001] This application relates to the field of mortar production equipment technology, and more specifically, to a feeding device for mortar production. Background Technology

[0002] During mortar production, a transport vehicle or conveyor belt feeds sand into a hopper, which is then lifted by a screw conveyor into a mixing hopper for mixing to form mortar. However, the hopper is not easy to clean.

[0003] In response, Chinese patent application number CN202420760350.7 discloses a feeding device for mortar production. This solution mainly involves setting a pipe groove and a limiting opening inside the feeding hopper. The feeding pipe is inserted into the pipe groove. Since the diameter of the limiting opening is smaller than that of the pipe groove, it has a limiting effect on one end of the feeding pipe. The threaded connection of the threaded connecting post and the threaded connection hole further enhances the stability of the connection between the feeding hopper and the feeding pipe, making it less likely to fall off. When cleaning or replacing the feeding hopper, it is only necessary to remove the threaded connecting post and lift the feeding hopper.

[0004] However, in the process of implementing the technical solutions in the embodiments of this application, the inventors of this utility model discovered that the above-mentioned technology has at least the following technical problems:

[0005] 1. The hopper needs to be lifted manually or by equipment and inserted into the feed pipe, which is inconvenient to operate;

[0006] 2. The feed pipe is fixed to the outer shell of the screw conveyor, which increases the dead corners for cleaning and makes it inconvenient to clean the conveyor. Summary of the Invention

[0022] The technical solution in this application embodiment is to solve the problems mentioned in the background art above, and the general idea is as follows:

[0023] Please see Figures 1-4This application provides a mortar production feeding device, including a hoist 10 and a hopper 20. The hoist 10 includes a pipe body 11 and a screw rod 12. The screw rod 12 rotates inside the pipe body 11, with its lower end exposed. The lower end of the hopper 20 is provided with a feeding port, and a material gate 30 is hinged to the feeding port. The material gate 30 encloses the exposed lower end of the screw rod 12 into the hopper 20. A support mechanism 80 is provided on the hopper 20 to support the lower end of the screw rod 12. The material gate 30 can be part of the pipe body 11. Opening the material gate 30 allows the hopper 20 to be separated horizontally. After separation, the hopper 20 can be cleaned, and the lower end of the screw rod 12 will also be exposed for easy cleaning of the hoist 10.

[0024] Please see Figures 1-4 It also includes a fixed frame 40 and a movable frame 50. The elevator 10 is mounted on the fixed frame 40, and the hopper 20 is mounted on the movable frame 50. The fixed frame 40 is used to support the elevator 10 and is usually fixed next to the mixing hopper. The hopper 20 is fixed on the movable frame 50 and can be pulled apart to allow for separate cleaning of the hopper 20 and the elevator 10. The lower end of the movable frame 50 is equipped with rollers for easy pushing.

[0025] Please see Figures 1-4 A positioning pin 60 is fixedly connected to the movable frame 50, and a positioning hole is provided on the fixed frame 40 to match the positioning pin 60. When the hopper 20 is installed on the elevator 10, the movable frame 50 approaches the fixed frame 40, and the positioning pin 60 is inserted into the positioning hole to achieve positioning of the movable frame 50 and the fixed frame 40, so that the hopper 20 and the elevator 10 can be accurately connected.

[0026] Please see Figures 1-4 A connecting plate 70 is detachably connected between the movable frame 50 and the fixed frame 40. After the fixed frame 40 and the movable frame 50 are connected, they are fixed together by the connecting plate 70 and screws.

[0027] Please see Figures 1-4 The support mechanism 80 includes a tray 81, which is fixedly connected to the hopper 20. The tray 81 has a rotating groove that matches the lower end of the screw rod 12. The inner wall of the rotating groove on the tray is fitted with a wear-resistant pad to provide durable support when the screw rod 12 rotates.

[0028] Please see Figures 1-4 The material gate 30 abuts against the outer circle of the tray 81. When the material gate 30 is closed, it is locked onto the hopper 20 by bolts, and is tightly fitted to the outer circle of the tray 81. A rubber gasket is placed at the fitting point to achieve a seal.

[0029] Please see Figures 1-4The support mechanism 80 also includes a stop block 82, which is slidably connected to the tray 81. The front end of the stop block 82 holds the screw rod 12 in the rotating groove. Since the hopper 20 and the screw rod 12 are horizontally close and connected, the stop block 82 is first pulled out to open the rotating groove. After the screw rod 12 enters the rotating groove, the stop block 82 is pushed in to hold the screw rod 12 in the rotating groove, thus achieving stable support.

[0030] Please see Figures 1-4 The rear end of the stop block 82 abuts against the material gate 30. After the stop block 82 is pushed in, the material gate 30 is closed, thereby locking the stop block 82 onto the tray 81. This eliminates the need for a special locking operation on the stop block 82, simplifying the operation.

[0031] The working principle of the mortar production feeding device is as follows: When the hopper 20 and the elevator 10 are separated, it is convenient to clean the hopper 20. Since the lower end of the screw rod 12 of the elevator 10 is exposed, the residue can be directly discharged from the lower end when cleaning the elevator 10, which is convenient for cleaning the inside of the elevator 10. When docking, the material gate 30 is opened and the hopper 20 is pushed towards the elevator 10. The positioning pin 60 is inserted into the positioning hole to realize the positioning of the movable frame 50 and the fixed frame 40 so that the hopper 20 and the elevator 10 can be accurately docked. Then, the connecting plate 70 and screws are used to fix the two together. At this time, the lower end of the screw rod 12 has entered the rotating groove. The abutment block 82 is pushed in to lock the screw rod 12 in the rotating groove to achieve stable support. Finally, the material gate 30 is closed and the material gate 30 is fixed with bolts to realize docking.

[0032] In summary, the material gate 30 can be used as part of the pipe body 11. Opening the material gate 30 allows the hopper 20 to be separated horizontally. After separation, the hopper 20 can be cleaned, and the lower end of the screw rod 12 will also be exposed to facilitate cleaning of the elevator 10.

[0033] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
