Description

Technical Field

[0001] This utility model belongs to the technical field of coal yard loading and unloading equipment, specifically relating to a spiral coal leveling machine. Background Technology

[0002] Train transportation is low-cost and has a large carrying capacity, making it the main mode of freight transportation. Currently, after the coal is loaded by coal loading machines or coal loading stations, the top of the car is uneven, which easily generates dust during transportation, reduces the amount of coal, and causes environmental pollution. Therefore, the upper layer of materials in the car needs to be flat.

[0003] Existing technologies include the use of loader modifications to scraper conveyors for coal leveling. However, for materials with high density or poor flowability, the working resistance of a pure scraper is relatively large, affecting the leveling efficiency. Moreover, the modified scraper conveyor is not highly specialized and cannot be used in conjunction with a coal loading machine or coal loading station.

[0004] Therefore, how to provide a spiral coal leveling machine is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a spiral coal leveler that can effectively level the uneven coal material on the top of the car body, facilitating subsequent transportation.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a spiral coal leveling machine, comprising:

[0007] The mounting frame has two flat material screws coaxially rotatably mounted on it.

[0008] A rotary power source, comprising two sets of rotary power sources respectively fixed to the two ends of the mounting frame, wherein the output shafts of the two sets of rotary power sources are respectively connected to the flat material screw on the side closest to the load.

[0009] The lifting scraper mechanism consists of two sets, which are arranged on both sides of the mounting frame. The two sets of lifting scraper mechanisms alternately scrape materials.

[0010] The beneficial effects of this utility model are: the mounting frame provides the mounting base for two leveling screws, and there are two sets of lifting scraper mechanisms set on both sides of the mounting frame. In this way, the material can be effectively scraped under the working path of the leveling screws during operation. Due to the initial leveling effect of the leveling screws, the scraping resistance of the scraper mechanism can be reduced, which can be used for leveling operations of materials with high density or poor flowability. The two sets of lifting scraper mechanisms can work alternately to adapt to the operation process of different leveling directions.

[0011] Preferably, the spiral blades of the two flat material spirals are installed in the same or opposite directions.

[0012] The resulting technical effect is that the two flat material augers can push the material in the middle to both sides, or change the direction of rotation to bring the material on both sides to the middle, and then work with the subsequent scraper mechanism to level it. They can also rotate in opposite directions to allow the material to be spread from left to right.

[0013] Preferably, two sets of hanging bearings are connected to the middle of the bottom side of the mounting frame, and the two sets of hanging bearings are respectively connected to the shafts of the two flat material screws and support their rotation.

[0014] The resulting technical effect is that the use of hanger bearings to provide end rotation support for the flat material auger avoids its cantilever rotation, while also improving the installation stability and operational reliability of the flat material auger.

[0015] Preferably, the rotary power source is either a hydraulic motor or an electric motor, and the output shaft of the rotary power source is connected to the input shaft of a reducer. The output shaft of the reducer is driven by a chain to the flat material screw on the near side.

[0016] The resulting technical effect is that the rotary power source drives the leveling screw to rotate after the speed reduction and torque increase of the reducer, which can adapt to leveling operations of different densities.

[0017] Preferably, the lifting scraper mechanism includes a hydraulic cylinder, a pull rod, a guide sleeve, and a scraper. The hydraulic cylinders are arranged vertically in pairs at both ends of the side of the mounting frame. The top end of the pull rod is fixedly connected to the telescopic end of the hydraulic cylinder, and the bottom end of the pull rod is fixedly connected to the scraper. The guide sleeve is fixedly connected to the mounting frame and guides the pull rod to move up and down. The hydraulic cylinders in the same group are connected to a hydraulic synchronous motor through pipelines, and the hydraulic synchronous motor is connected to an external hydraulic station through pipelines.

[0018] The resulting technical effects are: the lifting and lowering of the scraper on the same side is controlled by dual cylinders, the hydraulic synchronous motor ensures that the hydraulic cylinders in the same group operate in the same manner, and the guide sleeve and tie rod work together to provide guidance while also improving the scraper's resistance performance.

[0019] Preferably, it also includes a gantry, on which a lifting slide is connected, and the bottom end of the lifting slide is fixedly connected to the mounting frame.

[0020] The resulting technical effect is that the gantry provides space for the carriage operation, the lifting carriage can be raised and lowered by the lifting cylinder, and the raising and lowering of the lifting carriage drives the installation frame to rise and fall, thereby realizing the subsequent material leveling operation process.

[0030] The lifting scraper mechanism 4 has two sets and is set on both sides of the mounting frame 1. The two sets of lifting scraper mechanisms 4 alternately scrape the material.

[0031] During installation, the spiral blades of the two leveling spirals 2 can be installed in the same or opposite directions, using forward and reverse rotation control to level the material at both ends or gather it in the middle. Alternatively, one can rotate forward and the other reverse to allow the material to be exchanged and leveled from left to right.

[0032] In other embodiments, two sets of hanging bearings 5 ​​are connected to the bottom center of the mounting frame 1. The two sets of hanging bearings 5 ​​are respectively connected to the shafts of the two flat material screws 2 and support their rotation, so as to ensure the stability of the operation and the reliability of the operation of the two flat material screws.

[0033] In some other specific embodiments, the rotary power source 3 is either a hydraulic motor or an electric motor. The output shaft of the rotary power source 3 is connected to the input shaft of the reducer 6. The output shaft of the reducer 6 is driven by a chain to the flat material screw 2 on the side. The flat material screw is a combination of a shaft and a screw blade. The shaft is mounted on the mounting frame through a bearing seat. During transmission, a necessary sprocket is used.

[0034] In some other embodiments, the lifting scraper mechanism 4 includes a hydraulic cylinder 41, a pull rod 42, a guide sleeve 43, and a scraper 44. The hydraulic cylinders 41 are arranged vertically in pairs on both sides of the mounting frame 1.
