Description

Technical Field

[0001] This utility model relates to the field of excavator technology, and specifically to an excavator bucket structure. Background Technology

[0002] Excavating machinery is one of the main types of engineering and construction machinery. As an important component of the excavator's working device, the quality of the bucket's structure directly affects the overall quality and efficiency of the excavator's work. However, the bucket structure in the existing technology generally has certain limitations.

[0003] A search revealed, for example, Chinese patent application CN222975970U, which discloses an excavator bucket structure including a bucket bottom plate and side plates disposed on both sides of the bottom plate. Several bucket bottom reinforcing plates are arranged side-by-side on the inner surface of the bottom plate, and a lower reinforcing plate is disposed on the lower part of the outer surface of the side plates. Several upper reinforcing plates are disposed on the upper part of the outer surface of the side plates, with the upper reinforcing plates arranged sequentially at intervals on the outer surface of the side plates. This invention can protect the surfaces of the bottom plate and side plates, reduce wear, and improve the structural strength of the bucket, thereby increasing the service life of the bucket.

[0004] During earthmoving operations, the inside of the bucket will absorb sticky soil. This sticky soil will occupy the effective volume of the bucket cavity, resulting in a decrease in the actual loading capacity. This requires multiple empty bucket cleanings, which prolongs the operation cycle. Utility Model Content

[0005] The purpose of this invention is to provide an excavator bucket structure that, through a cleaning component, can not only push away the soil inside the bucket body, but also scrape off the sticky soil adhering to the inner wall of the bucket body. This solves the problem of reduced effective volume of the bucket cavity due to sticky soil adhering to the surface of the bucket body, thereby reducing work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an excavator bucket structure, including a bucket mechanism, wherein the bucket mechanism includes a bucket body, and the outer wall of the bucket body is symmetrically provided with through slots; The outer wall of the bucket body is provided with a cleaning mechanism located on the surface of the through groove; The cleaning mechanism includes a slide rail, and a cleaning component is installed inside the slide rail for cleaning the inside of the bucket body.

[0007] Preferably, the outer wall of the bucket body is fixedly connected with multiple bucket teeth, which are in contact with the soil and used for digging the soil.

[0008] Preferably, the cleaning assembly includes a connecting plate, which is slidably fitted into the sliding cavity of the slide rail. A baffle is fixedly connected to one bottom side of the connecting plate, and a scraper is fixedly connected to the other bottom side of the connecting plate. A blocking assembly located on the side of the connecting plate is provided inside the slide rail to prevent stones in the soil from entering the bucket body during operation.

[0009] Preferably, the blocking assembly includes a sliding plate, which is slidably fitted into the sliding cavity of the slide rail, and a grid frame is fixedly connected to the outer wall of the sliding plate.

[0010] Preferably, a lead screw is rotatably connected to the sliding cavity of the slide rail via a bearing, and the surface of the lead screw is threadedly connected to the connecting plate and the sliding plate respectively.

[0011] Preferably, a servo motor is fixedly connected inside the slide rail, and the output end of the servo motor is fixedly connected to one end of the lead screw.

[0012] Preferably, the outer wall of the slide rail is fixedly connected with a side shovel for digging soil on the side of the bucket body and blocking soil pushed out by the cleaning component.

[0013] Preferably, the inner wall of the bucket body is symmetrically and fixedly connected with discharge troughs for discharging the soil cleaned up by the cleaning components from the discharge troughs.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. The present invention relates to an excavator bucket structure, wherein a servo motor drives a cleaning component to move outward from the bucket body. During this process, the scraper and a baffle with a mud-blocking function are simultaneously moved outward. On the one hand, the movement of the scraper can push the soil inside the bucket body to the side, helping the soil to be discharged quickly. On the other hand, the scraper can simultaneously scrape off the sticky soil adhering to the inner wall of the bucket body during the movement, effectively preventing the sticky soil from continuously adhering and causing the effective volume of the bucket cavity to shrink, thereby ensuring the working efficiency of the bucket. 2. The excavator bucket structure of this utility model, through servo motor linkage control, can drive the cleaning component to move outward synchronously while driving the cleaning component, achieving the synergistic effect of "interception and protection during excavation and smooth mud discharge during unloading": During the excavation operation, the blocking component covers the end face of the bucket body, which can effectively intercept stones in the soil from entering the bucket cavity and prevent the scraper from being damaged by collision with stones during the movement; when the scraper pushes the soil in the bucket to unload, the blocking component moves outward, providing an unobstructed channel for soil discharge, helping the bucket to quickly complete unloading and significantly improving the ease of operation.

Detailed Implementation

[0018] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that the description of this disclosure will be more complete and fully convey the concept of the exemplary embodiments to those skilled in the art. The drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0019] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more exemplary embodiments. Numerous specific details are provided in the following description to give a full understanding of exemplary embodiments of this disclosure. However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced with one or more of the specific details omitted, or other methods, components, steps, etc., can be employed. In other instances, well-known structures, methods, implementations, or operations are not shown or described in detail to avoid obscuring aspects of this disclosure. Example 1:

[0020] This utility model provides, for example Figure 1-6 The excavator bucket structure shown includes a bucket mechanism 1, which includes a bucket body 11. The inner wall of the bucket body 11 is coated with a wear-resistant and non-stick coating, preferably polyurea. A plurality of bucket teeth 12 are fixedly connected to the outer wall of the bucket body 11. The bucket teeth 12 are in contact with the soil and are used to dig the soil.

[0021] The outer wall of the bucket body 11 is symmetrically provided with through slots 14, and the outer wall of the bucket body 11 is provided with a cleaning mechanism 2 located at the corresponding position of the through slots 14; The cleaning mechanism 2 includes a slide rail 21. The bottom of the slide rail 21 is fixedly connected to the top of the outer wall of the bucket body 11. The sliding inner cavity at the bottom of the slide rail 21 coincides with the position of the through groove 14. A cleaning component 23 is provided inside the slide rail 21 for cleaning the inside of the bucket body 11.

[0022] The cleaning component 23 includes a connecting plate 231, which is slidably fitted into the sliding cavity of the slide rail 21. A baffle 232 is fixedly connected to one side of the bottom of the connecting plate 231. The shape of the baffle 232 is the same as the side opening shape of the bucket body 11. A scraper 233 is fixedly connected to the other side of the bottom of the connecting plate 231. The blade of the scraper 233 conforms to the arc contour of the bucket wall and the bottom of the bucket, and can scrape off the soil adsorbed on the bucket wall and the bottom of the bucket.

[0023] Additionally, discharge troughs 13 are symmetrically fixedly connected to the inner wall of the bucket body 11, for discharging the soil cleaned by the cleaning component 23 from the discharge troughs 13. When the connecting plate 231 is located on the side of the sliding inner cavity of the slide rail 21 close to the inner wall of the bucket body 11, the baffle 232 is located on the side of the discharge chute 13 away from the inner wall. At this time, when the excavator is working, the excavated soil will be located between the baffle 232 and the scraper 233.

[0024] Furthermore, because the sliding inner cavity of the slide rail 21 is rotatably connected to the lead screw 26 via bearings, and the surface of the lead screw 26 is threadedly connected to the connecting plate 231, and the interior of the slide rail 21 is fixedly connected to the servo motor 25, the output end of the servo motor 25 is fixedly connected to one end of the lead screw 26, when it is necessary to empty the soil inside the bucket body 11, the servo motor 25 can drive the lead screw 26 to rotate. The rotation of the lead screw 26 can push the connecting plate 231 to move outward. At the same time as the connecting plate 231 moves outward, it will drive the baffle 232 and the scraper 233 to move outward. The baffle 232 will leave the surface of the bucket body 11, while the scraper 233 will move inside the bucket body 11. The scraper 233 can push the soil inside the bucket body 11 to move outward and scrape off the soil adsorbed on the inner wall of the bucket body 11.

[0025] Before use, the staff can start the servo motor 25, which drives the cleaning component 23 to move and clean the bucket body 11 before operation, so as to prevent the effective volume of the bucket body 11 from being reduced due to the stubborn mud adhering to the surface of the bucket body 11 during the whole process.

[0026] For a small amount of stubborn soil adhering to the surface, the scraper 233 removes the stubborn soil and then pours the soil into the discharge trough 13, from which the soil is discharged. Example 2:

[0027] To prevent stones in the soil from entering the bucket body 11 during excavation and causing damage to the scraper 233, this utility model provides a blocking component 24 located on the side of the connecting plate 231 inside the slide rail 21 to prevent stones in the soil from entering the bucket body 11 during operation.

[0028] The blocking component 24 includes a sliding plate 241, which is slidably connected to the sliding cavity of the slide rail 21. A grid frame 242 is fixedly connected to the outer wall of the sliding plate 241. The grid frame 242 is formed by welding wear-resistant steel strips. The surface of the grid frame 242 has multiple mesh holes with a diameter of 80mm, which can block most stones.

[0029] It should be noted that in the initial state, the surface of the sliding plate 241 of the bucket body 11 will be in contact with the side of the bucket body 11. At this time, the grid frame 242 will cover the port on the surface of the bucket body 11 without obstructing the bucket teeth 12 and without affecting the normal digging operation of the bucket. During the digging process, the soil will pass through the mesh on the surface of the grid frame 242 and enter the interior of the bucket body 11, while the stones inside the soil will be blocked by the grid frame 242.

[0030] The sliding plate 241 of the blocking component 24 is threadedly connected to the lead screw 26 and moves synchronously with the lead screw 26. Therefore, when it is necessary to push out the soil inside the bucket body 11, the sliding plate 241 can be moved outward while the servo motor 25 is started. When the sliding plate 241 moves to the end of the sliding cavity of the slide rail 21 away from the inner wall of the bucket body 11, the grid frame 242 will be fully unfolded to facilitate the discharge of the soil inside the bucket body 11.

[0031] It is worth noting that when the sliding plate 241 moves to the end of the sliding cavity of the slide rail 21 away from the inner wall of the bucket body 11, the scraper 233 will move to the side of the discharge trough 13 away from the inner wall of the bucket body 11.

[0032] The outer wall of the slide rail 21 is fixedly connected to a side shovel 22, which is used to dig the soil on the side of the bucket body 11 and block the soil pushed out by the cleaning component 23.

[0033] It is worth noting that the bottom of the side shovel 22 is also equipped with bucket teeth 12. Therefore, when digging, the side shovel 22 can penetrate deep into the soil to shovel soil from both sides, which plays an auxiliary role in digging. At the same time, it also has a limiting function on both sides of the soil to prevent the soil from falling off as the bucket body 11 moves and rises.

[0034] Meanwhile, when the cleaning component 23 pushes out the soil, the side shovel 22 can shield the soil to prevent it from flying too far and affecting the collection of the soil.

[0035] It should be noted that the cleaning mechanism 2 is set on both sides of the bucket body 11 and is controlled by two different servo motors 25. Therefore, when it is necessary to discharge the soil inside the bucket body 11, the two different servo motors 25 need to be turned on in sequence.

[0036] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
