Description

Technical Field

[0001] This utility model relates to the technical field of spiral suction ash trucks, specifically to a spiral suction ash truck unloading device. Background Technology

[0002] The spiral suction truck is a mechanical device used for conveying powdery materials such as fly ash and cement powder. It is mainly used in industrial settings such as power plants and cement plants. The spiral suction truck uses the spiral conveying principle to achieve short-distance, mobile material conveying. It is suitable for scenarios such as loading and unloading from warehouses, transferring materials between warehouses, and loading and unloading ships. It mainly handles powdery materials such as fly ash and cement powder, and can also convey harder granular materials such as corn and wheat. When using the spiral suction truck, an ash unloading device is required.

[0003] Although existing ash unloading devices meet users' needs to a certain extent, they still have certain shortcomings during use. Specific problems are as follows: there is often a large gap between the ash outlet of the ash unloading device and the collection vehicle. During the unloading process, the ash material is easily scattered and splashed under the action of gravity, which not only wastes the ash material but also pollutes the surrounding air and ground. Installation and positioning are cumbersome, and the unloading efficiency is low. Traditional ash unloading devices are mostly fixed or semi-fixed structures. The docking with the ash discharge cylinder of the screw conveyor requires repeated manual adjustment of the position, and there is a lack of precise positioning mechanism. The docking process is time-consuming and laborious, prolonging the ash unloading preparation time, reducing the overall operation efficiency, and making it difficult to meet the needs of continuous ash unloading. Based on this, this utility model designs a screw-type ash suction vehicle unloading device to solve the above problems. Utility Model Content

Detailed Implementation

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Example: Figure 1-4 As shown, this utility model provides a technical solution: a spiral suction ash unloading device, including a spiral conveyor 1, a drive motor 2 fixedly connected to one end of the spiral conveyor 1, a drive gear 3 fixedly connected to the output shaft of the drive motor 2, a drive rack 4 meshing with one end of the drive gear 3, a connecting cylinder 5 fixedly installed at one bottom end of the drive rack 4, a connecting rod 6 fixedly connected to one end of the connecting cylinder 5, the connecting rod 6 being connected to the top of the drive rack 4 via a positioning plate 7, and a fixing cylinder 8 installed inside the connecting cylinder 5 via screws;

[0023] The top two ends of the fixed cylinder 8 are each equipped with a first electric telescopic column 9 by screws. The tops of the two first electric telescopic columns 9 are connected by an insertion cylinder 10. The bottom two ends of the fixed cylinder 8 are each equipped with a second electric telescopic column 11 by screws. The bottoms of the second electric telescopic columns 11 are connected by an extension cylinder 12.

[0024] A rectangular rod 13 is installed at one end of the extension tube 12 by screws. A drive rack 14 is installed at the top of the rectangular rod 13 by screws. A drive gear 15 is meshed at one end of the drive rack 14. A closing plate 16 is fixedly installed at one end of the drive gear 15.

[0025] Both the insertion cylinder 10 and the extension cylinder 12 are slidably connected inside the fixed cylinder 8. The top of the extension cylinder 12 is provided with an arc corner. The top of the insertion cylinder 10 is inside the screw conveyor 1, which facilitates the installation of the ash unloading device and the guidance of ash, thus avoiding the problem of ash accumulating on the top of the extension cylinder 12.

[0026] The sealing plate 16 is rotatably connected to the inside of the fixed cylinder 8 via a rotating shaft. The drive gear 15 is fixedly connected to one end of the rotating shaft. The outer side of the sealing plate 16 is in contact with the inner wall of the fixed cylinder 8, which facilitates sealing the inside of the fixed cylinder 8 and facilitates driving the sealing plate 16 to rotate.

[0027] The positioning plate 7 is arc-shaped and fits into the outer side of the screw conveyor 1, which facilitates the positioning of the fixed cylinder 8 and makes it easier to rotate it to the appropriate position.

[0028] After the personnel move the spiral suction trolley to a suitable position, they turn on the drive motor 2, which drives the gear 3 to rotate. The rotation of the gear 3 drives the rack 4 to rotate, rotating the fixed cylinder 8 to the bottom of the ash discharge cylinder of the spiral conveyor 1. Then, the first electric telescopic column 9 is activated, pushing the insertion cylinder 10 to move inside the ash discharge cylinder of the spiral conveyor 1. Then, the second electric telescopic column 11 is activated, driving the extension cylinder 12 to move. The movement of the extension cylinder 12 drives the rectangular rod 13 and the drive rack 14 to move. The movement of the drive rack 14 drives the drive... The gear 15 rotates, which in turn drives the closing plate 16 to rotate, opening the fixed cylinder 8 so that the ash can fall from inside the ash discharge device. By adjusting the extension cylinder 12, the distance between the ash discharge cylinder and the collection vehicle can be reduced, reducing the problem of ash splashing and affecting the surrounding air. It also facilitates the installation and positioning of the ash discharge device, making it easier to discharge ash from the spiral ash suction vehicle. At the same time, it is easy to close the fixed cylinder 8 to stop ash discharge. After ash discharge is completed, the operation can be reversed to rotate the ash discharge device to the bottom of the spiral conveyor 1 for storage, reducing the space occupied by the ash discharge device.
