Description

Technical Field

[0001] This utility model relates to the field of loader accessories technology, and in particular to a loader bucket dust cover that is linked to the boom. Background Technology

[0002] Loaders, as an important type of earthmoving machinery, are widely used in mines, ports, construction sites and other places for loading and transporting bulk materials such as coal, sand, gravel and soil.

[0003] In actual operation, after the traditional loader bucket has finished loading the material, the bucket opening remains open throughout the entire transportation and lifting process. When the loader is moving or the boom is operating, the airflow disturbance and vehicle bumps can easily stir up the fine particles in the bucket, especially the surface layer, forming dust. This phenomenon is particularly serious when loading and unloading dry, powdery materials. The resulting dust not only directly causes material loss, but more importantly, it spreads into the surrounding environment, causing a sharp decline in the air quality of the work area, posing a threat to the health of on-site workers, and also polluting the surrounding environment, which does not meet increasingly stringent environmental protection requirements.

[0004] Therefore, this utility model proposes a loader bucket dust cover that is linked to the boom to solve the shortcomings of the prior art. Utility Model Content

[0005] In view of the serious dust problem caused by the open bucket opening of loader buckets when loading and transporting bulk materials in the existing technology, this utility model aims to provide a loader bucket dust cover with improved structure that can effectively solve the above-mentioned problem and is linked to the boom.

[0006] This utility model provides a loader bucket dust cover that is linked to the boom, which includes a bucket body and a dust prevention mechanism.

[0007] The dustproof mechanism includes a hinged bracket, a first dust cover, a second dust cover, a first electric telescopic rod, and a second electric telescopic rod. The hinged bracket is fixed to the upper opening edge of the bucket body, providing a foundation for the installation of the dust cover. The first dust cover is hinged to the hinged bracket, forming the main body of the cover structure. The second dust cover is hinged to the first dust cover, together forming a foldable complete cover. The two ends of the first electric telescopic rod are respectively hinged between the bucket body and the first dust cover, used to drive the first dust cover to open and close. The two ends of the second electric telescopic rod are respectively hinged between the first dust cover and the second dust cover, used to control the unfolding and folding of the second dust cover relative to the first dust cover. Through the coordinated control of these two electric telescopic rods, the opening and closing of the entire dustproof mechanism can be accurately realized, thereby effectively covering the opening of the bucket body.

[0008] Preferably, the loader bucket dust cover also includes a connecting lug, which is fixedly connected to the outer wall of the bucket body. This structure provides a standardized interface for the entire bucket device, enabling reliable connection and fixation between the entire device and the loader boom.

[0009] Preferably, the loader bucket dust cover also includes a telescopic mechanism, which is installed at the bottom of the bucket body. This mechanism is designed to give the bucket the ability to adjust its digging depth to adapt to different working conditions and material characteristics.

[0010] Preferably, the telescopic mechanism includes a tooth base plate, a connecting block, and a hydraulic telescopic rod. The tooth base plate is slidably connected to the bucket body through the connecting block, and the hydraulic telescopic rod is installed in the bucket body. The telescopic rod of the hydraulic telescopic rod is fixedly connected to the connecting block, thereby enabling precise and stable control of the reciprocating sliding of the tooth base plate through hydraulic power. More preferably, bucket teeth are fixedly installed at the front end of the tooth base plate, forming a complete digging component. The extension or retraction of the bucket teeth can be achieved by adjusting the telescopic mechanism.

[0011] Preferably, the loader bucket dust cover also includes a scraping mechanism, which is installed inside the bucket body and is used to automatically clean the sticky or wet materials adhering to the inner wall of the bucket after unloading, thereby improving the thoroughness of unloading.

[0012] Preferably, the scraping mechanism includes a DC motor, a scraper, and a connecting rod. The DC motor is fixed to the inner wall of the bucket body as a power source, providing rotational power for the scraping action. The connecting rod serves as a transmission component, with one end connected to the output shaft of the DC motor and the other end fixedly connected to the scraper, forming a complete rotating scraping system. More preferably, the edge shape of the scraper conforms to the inner wall of the bucket body. This design ensures that the scraper can contact and clean the inner wall to the maximum extent during rotation, thereby improving cleaning efficiency.

[0013] This utility model has the following beneficial effects: 1. This utility model solves the problem of dust generation and environmental pollution caused by the open opening of the loader bucket during operation by setting a folding cover plate composed of a first dust cover and a second dust cover, and by using the first electric telescopic rod and the second electric telescopic rod to drive its opening and closing. It achieves the technical effect of effectively covering the bucket opening during loading and transportation, reducing dust and protecting the environment.

[0014] 2. This utility model, by setting up a telescopic mechanism driven by a hydraulic telescopic rod, realizes the telescopic adjustment of the bucket teeth relative to the bucket body, which solves the problem in the prior art that the length of the loader bucket teeth is fixed, resulting in poor adaptability to materials with different physical properties and affecting loading efficiency. It achieves the technical effect of flexibly adjusting the loading state according to the material characteristics, improving operational adaptability and efficiency.

[0015] 3. This utility model solves the problem in the prior art that materials easily remain on the inner wall of the bucket, requiring manual cleaning, which is labor-intensive and affects the continuity of operation. It achieves the technical effect of automatically cleaning residual materials on the inner wall of the bucket, reducing manual intervention, and improving the continuity of operation and the thoroughness of unloading.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please refer to Figures 1 to 4 This utility model provides a loader bucket dust cover that is linked to the boom, which aims to solve the problem in the prior art where the loader bucket is open during operation, which easily causes material dust to be stirred up and pollute the environment.

[0020] like Figure 1 As shown, the loader bucket dust cover includes a bucket body 5, which serves as the core load-bearing component, and also includes a connecting lug 4, which is fixedly connected to the outer wall of the bucket body 5 to fix the entire device to the boom of the loader.

[0021] like Figure 1 and Figure 2 As shown, the dustproof mechanism 1 is installed on the upper part of the bucket body 5. The dustproof mechanism 1 includes a hinge bracket 104, which is fixed to the upper opening edge of the bucket body 5. The first dust cover 101 is hinged to the hinge bracket 104, and the second dust cover 102 is hinged to the first dust cover 101. The first dust cover 101 and the second dust cover 102 form a two-section foldable cover structure. The two ends of the first electric telescopic rod 103 are respectively hinged to the bucket body 5 and the first dust cover 101. The two ends of the second electric telescopic rod 105 are respectively hinged to the first dust cover 101 and the second dust cover 102. The first electric telescopic rod 103 and the second electric telescopic rod 105 work together to control the unfolding and folding of the first dust cover 101 and the second dust cover 102, thereby covering the opening of the bucket body 5.

[0022] Further, please refer to Figure 3The loader bucket dust cover also includes a telescopic mechanism 2, which is installed at the bottom of the bucket body 5. The telescopic mechanism 2 includes a toothed plate 201, a connecting block 203, and a hydraulic telescopic rod 204. The toothed plate 201 is slidably connected to the bucket body 5 through the connecting block 203. The hydraulic telescopic rod 204 is installed inside the bucket body 5, and the telescopic rod of the hydraulic telescopic rod 204 is fixedly connected to the connecting block 203.

[0023] Specifically, multiple bucket teeth 202 are fixedly installed at the front end of the tooth base plate 201. The hydraulic telescopic rod 204 serves as a power source. When the telescopic rod extends or retracts, it can push the connecting block 203 to move. Since the connecting block 203 is fixed to the tooth base plate 201, the movement of the connecting block 203 drives the tooth base plate 201 and the bucket teeth 202 to extend or retract relative to the bucket body 5. This telescopic structure enables the bucket to adapt to the loading requirements of different materials.

[0024] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, in order to achieve material cleaning inside the bucket and prevent material residue, please refer to the following: Figure 1 and Figure 4 The loader bucket dust cover also includes a scraping mechanism 3, which is installed inside the bucket body 5. Specifically, the scraping mechanism 3 includes a DC motor 303, which is fixed to the inner wall of the bucket body 5, a scraper 301, and a connecting rod 302. One end of the connecting rod 302 is connected to the output shaft of the DC motor 303, and the other end is fixedly connected to the scraper 301. As a further preferred embodiment, the edge shape of the scraper 301 fits against the inner wall of the bucket body 5. This fitting arrangement allows the scraper 301 to more effectively scrape off the material adhering to the inner wall of the bucket body 5 when it rotates.

[0025] The working principle of this utility model of a loader bucket dust cover that is linked to the boom is as follows: When operation is required, the entire device is first fixedly connected to the boom of the loader via the connecting lug 4. When the boom of the loader moves, the dustproof mechanism 1 starts to work, activating the first electric telescopic rod 103. The telescopic movement of the first electric telescopic rod 103 drives the first dust cover 101 to rotate around the hinge bracket 104. At the same time, the second electric telescopic rod 105 is activated. The movement of the second electric telescopic rod 105 causes the second dust cover 102 to unfold or fold relative to the first dust cover 101, ultimately achieving dust protection coverage above the bucket body 5 and preventing dust from spreading during operation.

[0026] During loading operations, the telescopic mechanism 2 is operated, and the telescopic rod of the hydraulic telescopic rod 204 extends and retracts, pushing the connecting block 203 to move. The movement of the connecting block 203 causes the tooth seat plate 201 and the bucket teeth 202 to extend and retract to adapt to the loading requirements of different materials. During operation, the scraping mechanism 3 can be activated, and the output shaft of the DC motor 303 rotates and drives the connecting rod 302 to rotate. The connecting rod 302 then drives the scraper 301 to slide against the inner wall of the bucket body 5 to remove residual materials.

[0027] After the operation is completed, the hydraulic telescopic rod 204 retracts, driving the bucket teeth 202 to reset. At the same time, the first electric telescopic rod 103 and the second electric telescopic rod 105 work together to fold and retract the first dust cover 101 and the second dust cover 102. At this time, the DC motor 303 can drive the scraper 301 again to complete the final cleaning work. Throughout the process, the various mechanisms cooperate to ensure the dust prevention effect and improve the loading and cleaning efficiency.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
