Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figure 1 As shown, a lubricating grease collection and cleaning device for a rotary mechanism includes an annular baffle, a guide component, and a collection component 5. The annular baffle has at least one notch and is coaxially arranged on an annular support plate inside the rotary support ring. A grease collection channel 100 is formed between the annular baffle and the rotary support ring to collect lubricating grease leaking from the meshing point between the rotary reducer and the rotary support ring. The guide component is installed on the annular support plate inside the annular baffle. The inlet end of the guide component is connected to the notch of the annular baffle, and the outlet end of the guide component extends to the center hole of the annular support plate. The collection component 5 is installed on the frame located directly below the outlet end of the guide component. The guide component guides the lubricating grease in the grease collection channel into the collection component 5, and the collection component discharges the lubricating grease to an external oil receiving device.

[0025] As can be seen from the above, this utility model aims to solve the problem of lubricating grease leakage in the slewing mechanism of existing excavators, which leads to dirty equipment and inconvenient cleaning. This utility model, through the cooperation of annular baffles, guide components, and collection components, constructs a complete path for grease collection, guidance, and discharge, achieving effective collection and cleaning of leaked grease, keeping the equipment clean, and reducing maintenance workload.

[0026] Preferred solutions, such as Figure 1 , Figure 2As shown, the annular baffle is composed of two oppositely arranged arc-shaped plates 1 and 2. The arc-shaped plates 1 and 2 are provided with two oppositely arranged notches, and each notch is provided with a guide component and a collecting component 5.

[0027] It should be noted that the above is only a preferred embodiment. Of course, in actual design, three or four notches can be designed according to actual needs.

[0028] The specific structure of the aforementioned guide component will be further explained below.

[0029] like Figure 3 , Figure 4 As shown, the guide component consists of two guide plates 3 and 4 arranged opposite to each other. One end face of the two guide plates 3 and 4 is fixed to the two end faces of the corresponding annular baffle notch, and the bottom surface of the guide plates 3 and 4 is attached to the annular support plate. The gap between the two guide plates 3 and 4 forms a grease guide channel.

[0030] Further options, such as Figure 3 , Figure 4 As shown, guide plates 3 and 4 are L-shaped plates. The end face of the short side of the L-shaped plate is welded to the end face of the notch, and the bottom face of the long side of the L-shaped plate is welded to the annular support plate.

[0031] As shown above, the arc-shaped plates 1 and 2 are made of steel plates, and their dimensions match the circumference of the excavator's slewing bearing ring. They are fixed by welding, and their main function is to form a grease collection channel defense line, preventing grease squeezed out from the meshing point from spreading and splashing radially. The guide plates 3 and 4 are also made of steel plates, usually formed into the required shape through a bending process. The guide plates 3 and 4 have symmetrical slits on their short sides and are welded together with the arc-shaped plates 1 and 2. The gap between the two guide plates 3 and 4 forms a grease guiding channel. The grease guiding channel can directly introduce the grease accumulated in the grease collection channel into the middle part of the vehicle body, and use the grease's own fluidity and auxiliary scraping force to guide it to flow along the channel towards the middle of the frame.

[0032] The following provides a further explanation of the specific structure of the aforementioned collection components.

[0033] like Figure 5 , Figure 6 , Figure 7 As shown, the collecting component 5 includes mounting seats 6 and 7, connecting seat 5-2, and collecting plate 5-1; mounting seats 6 and 7 are fixed on the frame located below the annular support plate; connecting seat 5-2 is assembled on mounting seats 6 and 7; collecting plate 5-1 is fixed obliquely on connecting seat 5-2, and the inlet end of collecting plate 5-1 is higher than the outlet end of collecting plate 5-1, and the inlet end of collecting plate 5-1 is connected to the outlet end of the guide component.

[0034] Further options, such as Figure 5 , Figure 6 , Figure 7 As shown, mounting bases 6 and 7 are provided with multiple threaded holes, and connecting base 5-2 is provided with multiple through holes that correspond one-to-one with the threaded holes. By using bolts to engage with the coaxially arranged threaded holes and through holes, connecting base 5-2 and mounting bases 6 and 7 are fixed together.

[0035] Further options, such as Figure 5 , Figure 6 , Figure 7 As shown, mounting bases 6 and 7 are U-shaped plates. The end faces of the two vertical parts of the U-shaped plate are welded to the frame. The horizontal part of the U-shaped plate has multiple light holes. The inner side of the horizontal part of the U-shaped plate is fixed with a threaded post coaxial with the light holes, and the threaded post has a threaded hole.

[0036] Further options, such as Figure 5 , Figure 6 , Figure 7 As shown, the connecting seat 5-2 consists of two L-shaped plates arranged opposite each other. The short side of the L-shaped plate is assembled on the mounting seats 6 and 7, and the end face of the long side of the L-shaped plate is set as an inclined surface. The collecting plate 5-1 is fixed on the inclined surface of the two L-shaped plates.

[0037] Further options, such as Figure 7 As shown, the collecting plate 5-1 is a U-shaped plate, and the tilt angle of the collecting plate 5-1 is 30° to 45°.

[0038] As shown above, the collecting plate 5-1 is the final collection and discharge component for grease. It is made of welded steel plates and is bolted to the mounting seats 6 and 7, which are welded and fixed to the vehicle frame. To ensure smooth grease flow, the collecting plate 5-1 is inclined. The inlet end of the collecting plate 5-1 smoothly connects to the outlet of the guide collection channel, while the other end serves as an oil drain. Containers such as oil collection drums can be placed below it.

[0039] The following describes the working process of the above-mentioned rotary mechanism lubricating grease collection and cleaning device.

[0040] When lubricating grease leaks from the meshing point between the slewing reducer and the slewing support ring, it is first blocked by the retaining rings on both sides, preventing it from splashing outwards. Subsequently, the grease accumulates in the guide collection channel formed by the arc-shaped plate and guide plate, flowing downwards along the channel. Finally, the grease converges on the inclined collection plate located at the bottom of the channel, and is discharged along its inclined surface to the external oil receiving device, thus completing the entire process of collection, guidance, and discharge.

[0041] In summary, this utility model provides a lubricating grease collection and cleaning device for rotary mechanisms, achieving the following functions and effects: 1. Excellent collection effect: Through the coordinated operation of the annular baffle, guide plate and inclined collection plate, a semi-enclosed collection system is formed around the meshing point, which can collect the lubricating grease leaking from the meshing point of the rotary reducer and the rotary support ring in a comprehensive and efficient manner, fundamentally avoiding the problem of grease splashing everywhere and contaminating the equipment.

[0042] 2. High ease of cleaning: This device collects scattered leaked grease and guides it to a fixed outlet, directly discharging it to an external oil receiving device; maintenance personnel only need to clean or replace the external oil receiving device periodically, eliminating the need to spend time and effort cleaning a large area of ​​the vehicle frame roof, greatly reducing the workload of maintenance.

[0043] 3. Keep equipment clean: Effectively prevents grease from contaminating the top plate of the chassis and surrounding parts, keeping the excavator's slewing mechanism area clean at all times, improving the overall appearance of the equipment, and also improving the maintenance working environment.
