Description

Technical Field

[0001] This application relates to the field of unloading equipment technology, and in particular to a hydraulically driven auger drive mechanism for a large-diameter unloading machine. Background Technology

[0002] The auger drive for the self-rotating hopper is usually driven by a motor reducer or a hydraulic motor. If a motor reducer is used, the drive mechanism is often huge. If the motor is built into the machine compartment, a power slip ring is required, which makes it difficult to meet the safety requirements for dust explosion prevention. If the motor is fixed externally, a complex gear steering structure is required, which is complex, has high installation requirements, high cost, and is difficult to maintain.

[0003] When using a motor reducer to change the auger speed, a frequency converter and a variable frequency motor are required. Additionally, when materials clump together, the auger drive motor may stall, and excessive starting current can easily burn it out. If a direct-drive motor is used, the large-diameter auger requires a high-displacement hydraulic motor due to its low-speed, high-torque requirements, making selection difficult. Furthermore, the hydraulic motor itself requires a large space, resulting in a cramped central machine compartment, making maintenance difficult, and increasing the size of the central machine compartment is detrimental to safety. Utility Model Content

[0004] In order to improve the efficiency of the hydraulically driven auger drive mechanism for large-diameter silo discharge machines during operation, this application provides a hydraulically driven auger drive mechanism for large-diameter silo discharge machines.

[0005] This application provides a hydraulically driven auger drive mechanism for a large-diameter silo discharge machine, employing the following technical solution: A hydraulically driven auger drive mechanism for a large-diameter hopper discharge machine includes a machine housing, a central turntable mounted on the machine housing, a hopper connected to the machine housing, a reducer bracket connected to the central turntable, and a reducer mounted on the reducer bracket. The machine housing has a hole through which the output shaft of the reducer passes and is connected to an auger assembly. The reducer employs a dual-input spatial staggered shaft arrangement, including two input ends connected to a self-rotating hydraulic motor. A hydraulic rotary distributor is mounted on the hopper, and hydraulic oil pipes are connected to the hydraulic rotary distributor. The self-rotating hydraulic motors are connected to the hydraulic rotary distributor via the hydraulic oil pipes, and a hydraulic pump station is connected to the hydraulic rotary distributor.

[0006] By adopting the above technical solution, the hydraulic pump station provides power, which is transmitted to the self-rotating hydraulic motor through a hydraulic rotary distributor and hydraulic oil pipes. The self-rotating hydraulic motor drives the reducer, and the output shaft of the reducer drives the auger assembly to rotate, thereby realizing the material conveying. The reducer adopts a dual-input spatial staggered shaft arrangement, with two self-rotating hydraulic motors providing power, which can better meet the high torque requirements, and the structural layout is reasonable, which is conducive to optimizing the overall space.

[0007] In one specific implementation, the reducer is equipped with a cooling fan and a cooling hydraulic motor, the cooling fan being driven by the cooling hydraulic motor, and the cooling hydraulic motor being connected to the hydraulic oil pipe.

[0008] By adopting the above technical solution, the cooling hydraulic motor obtains power through the hydraulic oil pipe and drives the cooling fan to work. The cooling fan can dissipate heat from the reducer, avoiding the reducer from being affected by excessively high operating temperature over a long period of time, thus reducing its performance and service life.

[0009] In one specific implementation scheme, the input end of the reducer is a splined input, and the side of the reducer is provided with a mounting flange.

[0010] By adopting the above technical solutions, the splined input can make the connection between the input end and the self-rotating hydraulic motor more stable and the torque transmission more reliable; the mounting flange facilitates the installation and fixing of the reducer, improving the convenience and stability of installation.

[0011] In one specific implementation, the reducer bracket is bolted to the central turntable.

[0012] By adopting the above technical solution, the bolt connection method makes the installation and disassembly of the reducer bracket more convenient, and facilitates later maintenance and replacement.

[0013] In one specific implementation, the rotating part of the hydraulic rotary distributor is connected to the hopper, and the fixed part of the hydraulic rotary distributor is connected to the material cylinder.

[0014] By adopting the above technical solution, the rotating part of the hydraulic rotary distributor rotates synchronously with the hopper, and the fixed part is stably connected to the material cylinder. This ensures the stable delivery of hydraulic oil without affecting the rotation function of the hopper. At the same time, the material cylinder can be used to receive materials falling from the hopper, facilitating the centralized transfer of materials.

[0015] In one specific implementation, the top of the cabin is set in a conical shape.

[0016] By adopting the above technical solution, the conical top of the silo is conducive to the material gathering downwards under its own gravity, reducing the material residue at the top of the silo and improving the material discharge efficiency.

[0017] In one specific implementation, the hopper is provided with an installation cavity, and the hydraulic rotary distributor is disposed within the installation cavity.

[0018] By adopting the above technical solution, the mounting cavity provides installation space for the hydraulic rotary distributor, protects the hydraulic rotary distributor, reduces damage caused by external factors, and makes the overall structure more compact.

[0019] In one specific implementation, the inner walls of the machine compartment and the hopper are provided with an anti-stick coating.

[0020] By adopting the above technical solution, an anti-stick coating is set to prevent materials from adhering to the inner wall of the hopper and the inner wall of the machine compartment, which facilitates material discharge.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The use of a dual-input reducer in conjunction with a self-rotating hydraulic motor can better meet the demand for high torque, and is also conducive to optimizing the spatial layout and improving the working performance of the drive mechanism.

[0022] 2. By installing a cooling fan and a cooling hydraulic motor, the reducer can be effectively cooled, extending its service life. Attached Figure Description

Detailed Implementation

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a hydraulically driven auger drive mechanism for a large-diameter warehouse discharge machine, referring to... Figure 1 The machine includes a machine compartment 1, the top of which is conical. A central turntable 11 is fixedly installed on the machine compartment 1. A feed hopper 2 is connected to the machine compartment 1. A reducer bracket 31 is bolted to the feed hopper 2. The reducer bracket 31 is bolted to the central turntable 11. A reducer 3 is bolted to the reducer bracket 31. The output shaft 32 of the reducer 3 extends into the machine compartment 1 and is fitted with a coupling 33. A auger assembly 4 for winding material is fixedly installed on the output shaft 32 of the reducer 3 through the coupling 33. A hole is opened in the machine compartment 1, and the auger assembly 4 extends out of the machine compartment 1 through the hole.

[0030] When using the drive mechanism, the central turntable 11 is fixedly installed on the storage bin, and the machine bin 1 and the auger assembly 4 are installed inside the storage bin. When driving the material feeding, the reducer 3 controls the auger assembly 4 to rotate and roll the material into the feeding hopper 2, and the feeding hopper 2, machine bin 1, reducer 3 and auger assembly 4 rotate on the central turntable 11.

[0031] Reference Figure 1 , Figure 2 and Figure 3 The reducer 3 has mounting holes 34. The reducer 3 is mounted on the reducer bracket 31 with bolts at the mounting holes 34. The reducer 3 adopts a double input space staggered shaft arrangement. The input ends 35 on both sides are splined inputs. The side of the reducer 3 is provided with a mounting flange 36.

[0032] Reference Figure 1 , Figure 3 and Figure 4A self-rotating hydraulic motor 371 is fixedly installed on both sides of the displacement output shaft 32 of the reducer 3. The self-rotating hydraulic motor 371 drives the reducer 3 to control the rotation of the auger assembly 4. A cooling fan 372 is rotatably installed on the reducer 3 below the self-rotating hydraulic motor 371. A cooling hydraulic motor 373 that controls the operation of the cooling fan 372 is fixedly installed on the reducer 3. A hydraulic rotary distributor 374 is installed on the hopper 2. The hopper 2 is provided with an installation cavity 21. The hydraulic rotary distributor 374 is disposed in the installation cavity 21. The hydraulic rotary distributor 374 is prior art. The structure of the hydraulic rotary distributor 374 will not be described in this embodiment. The hydraulic rotary distributor 374 is divided into two parts: an upper rotating part and a lower fixed part. The rotating part of the hydraulic rotary distributor 374 is fixedly connected to the hopper 2, so that the upper rotating part of the hydraulic rotary distributor 374 can rotate with the hopper 2. The lower fixed part of the hydraulic rotary distributor 374 is fixedly connected to a material cylinder 5. In this embodiment, when using the material cylinder 5, other conveying equipment, such as a scraper conveyor or a conveying auger, is fixedly connected to the bottom of the material cylinder 5. The hydraulic rotary distributor 374 is connected to a hydraulic pump station. A hydraulic oil pipe 375 is connected to the hydraulic rotary distributor 374. The self-rotating hydraulic motor 371 and the cooling hydraulic motor 373 are supplied with oil through the hydraulic oil pipe 375 connected to the hydraulic rotary distributor 374.

[0033] During operation, hydraulic oil in the hydraulic pump station flows to the lower part of the hydraulic rotary distributor 374 and then to the upper part of the self-rotating hydraulic motor 371. The self-rotating hydraulic motor 371 drives the output shaft 32 of the reducer 3 to rotate the auger assembly 4, thereby realizing the self-rotation of the auger of the discharge machine. Both the self-rotating hydraulic motor 371 and the reducer 3 are located outside the hopper and discharge hopper 2, facilitating inspection and maintenance. Through the combination of the self-rotating hydraulic motor 371 and the reducer 3, the reducer 3 adopts a dual-input spatial staggered shaft structure, making the selection of the self-rotating hydraulic motor 371 easier. The parallel input of the two motors can achieve greater torque, lower cost, better starting performance, and significantly reduced structural complexity and space requirements of the machine hopper 1. At the same time, the hydraulic drive meets the dust explosion-proof requirements.

[0034] In this embodiment, the inner walls of the machine compartment 1 and the hopper 2 are provided with an anti-stick coating. The anti-stick coating is a polytetrafluoroethylene coating with a thickness of 0.1-0.5 mm to reduce the adhesion of materials to the inner walls of the machine compartment 1 and the hopper 2.

[0035] The implementation principle of this application embodiment is as follows: the hydraulic oil in the hydraulic pump station flows to the lower part of the hydraulic rotary distributor 374 and then flows to the upper part of the self-rotating hydraulic motor 371. The self-rotating hydraulic motor 371 drives the output shaft 32 of the reducer 3 to drive the auger assembly 4 to rotate, thereby realizing the self-rotation of the auger of the warehouse exit machine.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
