Description

Technical Field

[0001] This utility model relates to the field of screw conveyor technology, specifically a screw conveyor that facilitates the replacement of the auger shaft. Background Technology

[0002] A screw conveyor is a machine that uses a motor to drive a screw to rotate and push materials to achieve the purpose of conveying. It can convey horizontally, inclined or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance and convenient closed transportation. Screw conveyors are divided into two types in terms of conveying form: shafted screw conveyor and shaftless screw conveyor. In terms of appearance, they are divided into U-shaped screw conveyor and tubular screw conveyor.

[0003] When replacing the auger shaft of a U-shaped screw conveyor, it is necessary to remove the fastening screws connecting the front and rear bearings of the U-shaped screw conveyor housing to the auger shaft. During disassembly, the limited internal space obstructs the fastening screws, making disassembly difficult. Based on the above description of the defects in the prior art, this utility model designs a screw conveyor that facilitates the replacement of the auger shaft to solve this defect in the prior art. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a screw conveyor that facilitates the replacement of the auger shaft.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a screw conveyor that facilitates replacement of the auger shaft, comprising a conveyor base, a drive motor, an auger shaft, and a discharge pipe. The output end of the drive motor is provided with a rectangular extension shaft opposite to the inner wall of the conveyor base. A sliding sleeve is slidably fitted on the opposite end of the rectangular extension shaft. A rectangular mating shaft connected to the axis of the auger shaft is inserted into the opposite end of the sliding sleeve.

[0006] The surface of the conveyor base is provided with a mounting base, and a servo motor is provided on the outside of the mounting base. The output end of the servo motor is provided with a bidirectional threaded rod, and a pair of threaded moving seats are threadedly connected to the outside of the bidirectional threaded rod. The threaded moving seats are respectively connected to the two sliding sleeves.

[0007] In a preferred embodiment of this utility model, the drive motor is located outside the conveyor base, and the unloading pipe is connected to the lower surface of the conveyor base.

[0008] The above technical solution facilitates the discharge of conveyed materials through the unloading pipeline.

[0009] As a preferred embodiment of this utility model, a shaft seat that is connected to and rotates with the rectangular extension shaft on the right side is installed and fixed on the right side wall of the inner cavity of the conveyor base.

[0010] The above technical solution facilitates the connection and rotation of the rectangular extension shaft on the bearing seat.

[0011] As a preferred technical solution of this utility model, the opposite side of the sliding sleeve is provided with a rectangular slot with the same length and width as the cross section of the rectangular docking shaft.

[0012] The above technical solution facilitates the movement of the rectangular docking shaft and the insertion and docking of the sliding sleeve.

[0013] As a preferred technical solution of this utility model, the mounting base is provided with a limiting groove located outside the bidirectional threaded rod, and the width of the limiting groove is equal to the width of the threaded moving base.

[0014] By adopting the above technical solution, the threaded moving seat can be moved at the upper limit of the mounting seat through the limiting groove.

[0015] As a preferred embodiment of this utility model, the inner wall of the mounting base is provided with a movable seat that is rotatably connected to the bidirectional threaded rod.

[0016] The above technical solution facilitates the stable rotation of the bidirectional threaded rod on the mounting base via the movable seat.

[0017] As a preferred technical solution of this utility model, the bidirectional threaded rod is provided with a forward thread groove and a reverse thread groove on the outer sides of the middle, and the forward thread groove and the reverse thread groove are respectively threaded to the two threaded moving seats.

[0018] By adopting the above technical solution, it is ensured that when the bidirectional threaded rod rotates, it drives the threaded moving seat to move in opposite directions or in opposite directions.

[0019] As a preferred embodiment of this utility model, the vertical gap length between the conveyor base and the mounting base is greater than the diameter of the auger shaft.

[0020] The above technical solution facilitates the removal of the auger shaft from the conveyor base after disassembly.

[0021] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0022] This convenient screw conveyor for replacing the auger shaft uses a servo motor to drive a bidirectional threaded rod to rotate. The threaded moving seat is connected to the bidirectional threaded rod, causing the threaded moving seat to move in the opposite direction. This simultaneously drives the sliding sleeve to move outside the rectangular extension shaft, separating the sliding sleeve from the rectangular connecting shaft on the auger shaft. This allows the auger shaft to be separated from the overall screw conveyor, facilitating quick disassembly and replacement of the auger shaft. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-4 This embodiment of a screw conveyor for easy replacement of the auger shaft includes a conveyor base 1, a drive motor 2, an auger shaft 3, and a discharge pipe 4. The drive motor 2 is fixed to the left side of the conveyor base 1 by fastening screws. The discharge pipe 4 is connected to the lower surface of the conveyor base 1, facilitating the discharge of material through the discharge pipe 4 when the material is conveyed by the screw conveyor 1. A rectangular extension shaft 8 is provided at the output end of the drive motor 2 opposite to the inner wall of the conveyor base 1. The extension shaft 8 is connected and fixed to drive the rectangular extension shaft 8 to rotate. The right side wall of the inner cavity of the conveyor base 1 is equipped with a shaft seat 7 that rotates circumferentially with the rectangular extension shaft 8 on the right side. The opposite end of the rectangular extension shaft 8 is slidably fitted with a sliding sleeve 6. The inside of the sliding sleeve 6 is provided with a rectangular groove for the rectangular extension shaft 8 to slide in a direction. The opposite end of the sliding sleeve 6 is inserted with a rectangular docking shaft 5 that is connected and fixed to the axis of the auger shaft 3. The opposite surface of the sliding sleeve 6 is provided with a rectangular slot with the same length and width as the rectangular docking shaft 5.

[0030] It should be added that the drive motor 2 drives the sliding sleeve 6 on the rectangular extension shaft 8 to rotate, which in turn drives the auger shaft 3 on the rectangular docking shaft 5 to rotate. In conjunction with the rectangular extension shaft 8 at the other end, the auger shaft 8 rotates on the conveyor base 1 through the shaft seat 7, ensuring that when the auger shaft 3 rotates, the material put into the conveyor base 1 is spirally conveyed to the discharge pipe 4 at the other end for discharge.

[0031] A mounting base 9 is fixedly installed on the upper surface of the conveyor base 1. A servo motor 10 is fixedly installed on the right side of the mounting base 9 by fastening screws. A bidirectional threaded rod 11 is fixedly installed on the output end of the servo motor 10 by fastening screws. A pair of threaded moving seats 13 are connected to the external threads of the bidirectional threaded rod 11. The threaded moving seats 13 are respectively connected and fixed to the two sliding sleeves 6. A limiting groove located outside the bidirectional threaded rod 11 is opened on the lower surface of the mounting base 9. The width of the limiting groove is equal to the width of the threaded moving seat 13.

[0032] It should be added that the servo motor 10 is an existing technology device with the function of locking after rotation. The servo motor 10 drives the bidirectional threaded rod 11 to rotate in both directions, so that the two threaded moving seats 13 can move towards each other or in opposite directions under the action of linear limit. The setting of the limit groove prevents the bidirectional threaded rod 11 from driving the threaded moving seats 13 to rotate synchronously and deviate in the opposite direction when it rotates.

[0033] It should be noted that the bidirectional threaded rod 11 has a forward thread groove and a reverse thread groove respectively opened on the outer sides of the middle. The forward thread groove and the reverse thread groove are respectively threaded to the two threaded moving seats 13, which are symmetrically distributed on the left and right sides of the middle of the bidirectional threaded rod 11.

[0034] The vertical gap between the conveyor base 1 and the mounting base 9 is longer than the diameter of the auger shaft 3, which makes it easier to remove the auger shaft 3 through the gap after it is detached from the overall screw conveyor.

[0035] The working principle of the above embodiments is as follows:

[0036] When the auger shaft needs to be disassembled and replaced, the servo motor 10 is started to drive the bidirectional threaded rod 11 to rotate in the opposite direction on the movable seat 12. The threaded connection between the threaded movable seat 13 and the bidirectional threaded rod 11, as well as the limiting sliding of the conveyor seat 1 on the threaded movable seat 13, ensure that when the bidirectional threaded rod 11 rotates, it drives the two threaded movable seats 13 to move in opposite directions. When the threaded movable seats 13 move, they simultaneously drive the sliding sleeve 6 to slide in a direction on the rectangular extension shaft 8, so that the sliding sleeve 6 separates from the rectangular docking shaft 5 on the auger shaft 3, thereby detaching the auger shaft 3 from the overall screw conveyor, and thus realizing the quick disassembly and replacement of the auger shaft 3.

[0037] When installing the auger shaft 3, place the auger shaft 3 inside the conveyor base 1 between the two sliding sleeves 6, then start the servo motor 10 to drive the bidirectional threaded rod 11 to rotate in the forward direction. Based on the above principle, the sliding sleeves 6 move towards each other and are inserted into the rectangular docking shaft 5 on the auger shaft 3.

[0038] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
