Description

Technical Field

[0001] This utility model belongs to the field of loader technology, and more specifically, it relates to a material shaking device for loaders. Background Technology

[0002] Loaders are multi-functional engineering machines widely used in fields such as engineering construction, mining, agricultural production, and logistics warehousing. They mainly use a front-end bucket that can be raised, lowered, and tilted to complete tasks such as loading, transporting, unloading, and leveling sites.

[0003] In actual operation, materials (such as soil, sand, coal, etc.) often adhere to the inner wall or edge of the bucket due to stickiness, humidity or interparticle friction, resulting in incomplete unloading. This requires manual secondary cleaning or repeated bucket turning, which seriously reduces operating efficiency and increases energy consumption. Utility Model Content

[0004] To address the problem that materials with high moisture content tend to adhere to the inner wall of the bucket, this invention proposes a material shaking device for loaders to overcome the aforementioned technical problems existing in related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a material shaking device for a loader, including a base, a tilting component is provided on one side of the base, a bucket is provided at the tilting end of the tilting component, a plurality of scraping components are provided inside the bucket, a driving component is provided at the top of the bucket, the driving component is poweredly connected to the plurality of scraping components, and an intermittent shaking component is provided between the scraping components and the bucket.

[0007] The drive assembly is used to drive several scraping components to reciprocate inside the bucket, so that the scraping components reciprocate on the inner wall of the bucket, and the intermittent shaking assembly is used to drive the continuously moving scraping components to shake.

[0008] Furthermore, the tilting assembly includes a lifting frame, with its two ends rotatably connected to a base and a bucket, respectively. A lifting hydraulic cylinder is rotatably connected inside the base, with the lifting end of the lifting hydraulic cylinder rotatably connected to the lifting frame. A rotating frame is rotatably connected to the outside of the lifting frame, and a rotating rod is rotatably connected inside the rotating frame. One end of the rotating rod is rotatably connected to the bucket. A tilting hydraulic cylinder is rotatably connected inside the base, with the lifting end of the tilting hydraulic cylinder rotatably connected to the rotating frame.

[0009] Furthermore, the scraping assembly includes a movable base, which is movably connected to the top of the bucket. A connecting rod is provided at the bottom of the movable base, and a mounting frame is fixedly connected to the bottom end of the connecting rod. A scraper is fixedly installed inside the mounting frame, and the scraper is in contact with the inner wall of the bucket.

[0010] Furthermore, the drive assembly includes mounting plates, which are provided on both sides of the bucket. A drive screw is rotatably connected between the mounting plates. The movable seat is threadedly connected to the drive screw. A drive motor is provided on the top of the bucket corresponding to the drive screw.

[0011] Furthermore, a sprocket is fixedly connected to both the output end of the drive motor and the outer surface of the drive screw. A chain is engaged with the outer surface of the sprocket. A storage box is fixedly installed on one side of the bucket. The sprocket and the chain are both located inside the storage box.

[0012] Furthermore, the intermittent vibration component includes a gear, which is fixedly connected to the outer surface of the connecting rod. Several toothed plates are fixedly connected to the front of the bucket corresponding to the gear. A storage cylinder is fixedly connected to the top of the movable seat. A rotating shaft is rotatably connected inside the storage cylinder. The rotating shaft passes through the movable seat and is fixedly connected to the connecting rod. A return torsion spring is fixedly connected between the rotating shaft and the inner wall of the storage cylinder.

[0013] Furthermore, a shielding frame is fixedly installed on the front of the bucket, and a through groove is provided at the top of the shielding frame. The through groove passes through the shielding frame, and the connecting rod is movably connected to the through groove. A shielding plate is provided at the top and bottom of the shielding frame, and the connecting rod is rotatably connected to the shielding plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model uses a drive assembly to drive several scraping components to move on the inner wall of the bucket. The moving scraping end can scrape off the material adhering to the inner wall of the bucket. The above setting effectively avoids the situation where materials with excessive moisture adhere to the inner wall of the bucket. At the same time, it eliminates the need for frequent bucket flipping and manual secondary cleaning during unloading, thereby improving the efficiency of material transfer.

[0016] 2. When the movable seat is moved by the drive screw, the movable seat can drive the scraper to move through the rotating shaft, connecting rod and mounting frame. When the gear and toothed plate mesh with each other, as the movable seat moves continuously, the gear can drive the scraper to rotate through the connecting rod. When the gear and toothed plate separate, the return torsion spring drives the rotating shaft and scraper to return to their original positions through its own elasticity. At the same time, since there are multiple toothed plate arrays, the connecting rod can continuously rotate and return to its original position during the movement. The above-mentioned compound motion causes the scraper to generate high-frequency micro-amplitude vibration when it moves along the inner wall of the bucket. This not only effectively peels off the material adhering to the inner wall of the bucket, but also breaks the adhesion between the material and the working surface of the scraper through vibration, ensuring that the scraped material falls off naturally with the vibration and avoiding secondary adhesion on the scraper surface.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figures 1-8 As shown, this utility model is a material shaking device for a loader, including a base 1, a tilting component 2 is provided on one side of the base 1, a bucket 3 is provided at the tilting end of the tilting component 2, a plurality of scraping components 4 are provided inside the bucket 3, a driving component 5 is provided at the top of the bucket 3, the driving component 5 is poweredly connected to the plurality of scraping components 4, and an intermittent shaking component 6 is provided between the scraping components 4 and the bucket 3.

[0032] The drive assembly 5 is used to drive a plurality of scraping assemblies 4 to reciprocate inside the bucket 3, so that the scraping assemblies 4 reciprocate on the inner wall of the bucket 3, and the intermittent shaking assembly 6 is used to drive the continuously moving scraping assemblies 4 to shake.

[0033] The opening of the bucket 3 is controlled to face downward by the flipping component 2, so that the material inside the bucket 3 can fall down. Then, the scraping end of several scraping components 4 is driven by the drive component 5 to move back and forth on the inner wall of the bucket 3. At the same time, with the assistance of the intermittent shaking component 6, the scraping end can intermittently shake while moving back and forth.

[0034] The drive assembly 5 drives several scraping assemblies 4 to move on the inner wall of the bucket. The moving scraping end can scrape off the material adhering to the inner wall of the bucket. The above configuration effectively avoids the situation where materials with excessive moisture adhere to the inner wall of the bucket 3. At the same time, it is not necessary to frequently flip the bucket 3 and manually clean it again when unloading, thereby improving the efficiency of material transfer.

[0035] In one embodiment, the tilting assembly 2 includes a lifting frame 201, with its two ends rotatably connected to a base 1 and a bucket 3, respectively. A lifting hydraulic cylinder 202 is rotatably connected inside the base 1, with its lifting end rotatably connected to the lifting frame 201. A rotating frame 203 is rotatably connected to the outside of the lifting frame 201, with a rotating rod 204 rotatably connected inside the rotating frame 203. One end of the rotating rod 204 is rotatably connected to the bucket 3. A tilting hydraulic cylinder 205 is rotatably connected inside the base 1, with its lifting end rotatably connected to the rotating frame 203.

[0036] The lifting frame 201 is lifted by the lifting hydraulic cylinder 202. At this time, the lifting frame 201 can rotate on one side of the base 1. At the same time, the tilting hydraulic cylinder 205, the rotating frame 203 and the rotating rod 204 rotate synchronously, so that the bucket 3 can be lifted and lowered. When the height of the bucket 3 is raised to a suitable height, the tilting hydraulic cylinder 205 lifts the rotating frame 203. At this time, the rotating frame 203 can rotate on the lifting frame 201. The rotating lifting frame 201 can lift the bucket 3 through the rotating rod 204, so that the bucket 3 can rotate around the lifting frame 201. When the opening of the bucket 3 is facing downward, the material inside the bucket 3 can fall directly down.

[0037] In one embodiment, the scraping assembly 4 includes a movable base 401, which is movably connected to the top of the bucket 3. A connecting rod 402 is provided at the bottom of the movable base 401. A mounting frame 403 is fixedly connected to the bottom end of the connecting rod 402. A scraper 404 is fixedly installed inside the mounting frame 403 and contacts the inner wall of the bucket 3.

[0038] When most of the material falls from the inside of the bucket 3, several movable seats 401 are pushed. The movable seats 401 can drive the scraper 404 to move on the inner wall of the bucket 3 through the connecting rod 402 and the mounting frame 403. At this time, the material adhering to the inner wall of the bucket 3 can fall directly from the inside of the bucket 3 under the scraping of the scraper 404, thereby avoiding the phenomenon of material adhering to the inner wall of the bucket 3.

[0039] In one embodiment, the drive assembly 5 includes a mounting plate 501, which is provided on both sides of the bucket 3. A drive screw 502 is rotatably connected between the mounting plates 501. The movable seat 401 is threadedly connected to the drive screw 502. A drive motor 503 is provided on the top of the bucket 3 corresponding to the drive screw 502.

[0040] By rotating the drive screw 502 via the drive motor 503, the rotating drive screw 502 can simultaneously drive several movable seats 401 to move on the top of the bucket 3. At the same time, several scrapers 404, driven by the corresponding movable seats 401, can automatically scrape off the material adhering to the inner wall of the bucket 3. Simultaneously, the drive motor 503 can drive the drive screw 502 to rotate in both directions, so that the movable seats 401 can drive the corresponding scrapers 404 to move back and forth on the inner wall of the bucket 3. This arrangement ensures the effectiveness of scraping off the material adhering to the inner wall of the bucket 3.

[0041] The drive motor 503 starts and begins to rotate forward. Simultaneously, its built-in or external rotation count detection device (such as an encoder or Hall sensor) monitors and accumulates the rotation count in real time. When the accumulated rotation count precisely reaches the preset target value, the control system (such as a PLC, microcontroller, or dedicated driver) immediately issues a command: first, it cuts off the current forward drive signal of the drive motor 503, and then quickly generates and outputs a reverse drive signal. Under the action of the drive circuit, the direction of the current or the sequence of the magnetic field inside the drive motor 503 changes, thereby changing the torque direction. Simultaneously, the drive shaft of the drive motor 503 begins to rotate in the reverse direction. Afterward, the rotation count detection device is reset to zero or restarts accumulating the number of reverse rotations, preparing for the next possible action (such as stopping or rotating forward after reaching the set number of rotations again).

[0042] In one embodiment, for the drive motor 503, the output end of the drive motor 503 and the outer surface of the drive screw 502 are both fixedly connected to a sprocket 504, the outer surface of the sprocket 504 is engaged with a chain 505, and a storage box 506 is fixedly installed on one side of the bucket 3, with the sprocket 504 and the chain 505 both located inside the storage box 506.

[0043] By driving the drive motor 503, the drive motor 503 can drive the sprocket 504 on the drive screw 502 to rotate via the corresponding sprocket 504 and chain 505, thereby causing the drive screw 502 to rotate and drive several moving seats 401. The arrangement of the sprocket 504 and chain 505 allows the drive motor 503 to be positioned on top of the bucket 3, thus providing maximum protection for the drive motor 503 and effectively preventing damage to the drive motor 503 due to external impacts when shoveling materials. The storage box 506 can protect the sprocket 504 and chain 505, making them less susceptible to external influences during operation.

[0044] In one embodiment, the intermittent vibration component 6 includes a gear 601, which is fixedly connected to the outer surface of the connecting rod 402. A plurality of toothed plates 602 are fixedly connected to the front of the bucket 3 corresponding to the gear 601. A storage cylinder 603 is fixedly connected to the top of the moving seat 401. A rotating shaft 604 is rotatably connected inside the storage cylinder 603. The rotating shaft 604 passes through the moving seat 401 and is fixedly connected to the connecting rod 402. A return torsion spring 605 is fixedly connected between the rotating shaft 604 and the inner wall of the storage cylinder 603.

[0045] When the movable seat 401 drives the scraper 404 to move via the rotating shaft 604, connecting rod 402, and mounting frame 403, after the gear 601 meshes with the toothed plate 602, as the movable seat 401 moves continuously, the gear 601 can drive the connecting rod 402 and the rotating shaft 604 to rotate. The rotating connecting rod 402 then drives the scraper 404 to rotate. When the gear 601 separates from the toothed plate 602, the reset torsion spring 605 drives the rotating shaft 604 to reset through its own elasticity. At the same time, the scraper 404 resets. Since there are multiple toothed plates 602 in the array, the connecting rod 402 can continuously rotate and reset during the movement. This arrangement allows the scraper 404 to vibrate continuously during the movement, so that after the scraper 404 scrapes the material off the inner wall of the bucket 3, the material will not stick to the scraper 404.

[0046] In one embodiment, for the bucket 3 described above, a shielding frame 606 is fixedly installed on the front of the bucket 3, a through groove 607 is provided on the top of the shielding frame 606, the through groove 607 passes through the shielding frame 606, the connecting rod 402 is movably connected to the through groove 607, and shielding plates 608 are provided on the top and bottom of the shielding frame 606, and the connecting rod 402 is rotatably connected to the shielding plates 608.

[0047] The shielding frame 606 can shield the gear 601 and the toothed plate 602, preventing material from adhering between them and allowing them to mesh normally. Several connecting rods 402 can move normally through the through groove 607, and the shielding plate 608 can move synchronously under the drive of the connecting rods 402. This arrangement ensures that no matter how the connecting rods 402 move, the shielding plate 608 can always shield the through groove 607, thus ensuring the shielding effect of the shielding frame 606, while the gear 601 and the toothed plate 602 can mesh normally.

[0048] Through the above technical solution, 1. By driving the drive assembly 5 to drive several scraping assemblies 4 to move on the inner wall of the bucket, the moving scraping end can scrape off the material adhering to the inner wall of the bucket. The above setting effectively avoids the situation where materials with excessive moisture adhere to the inner wall of the bucket 3. At the same time, during unloading, it is not necessary to frequently flip the bucket 3 and manually clean it again, thereby improving the efficiency of material transfer; 2. When the drive screw 502 drives the moving seat 401 to move, the moving seat 401 can drive the scraper 404 to move through the rotating shaft 604, connecting rod 402 and mounting frame 403. When the gear 601 and the toothed plate 602 mesh with each other, as the moving seat 404 moves, the scraper 404 moves. As the 01 continuously moves, the gear 601 drives the scraper 404 to rotate via the connecting rod 402. When the gear 601 separates from the toothed plate 602, the reset torsion spring 605 uses its own elasticity to drive the rotating shaft 604 and the scraper 404 to reset. At the same time, since there are multiple toothed plates 602 in the array, the connecting rod 402 can continuously rotate and reset during the movement. The above-mentioned compound motion causes the scraper 404 to generate high-frequency micro-vibration when moving along the inner wall of the bucket. This not only effectively peels off the material adhering to the inner wall of the bucket 3, but also breaks the adhesion between the material and the working surface of the scraper through vibration, ensuring that the scraped material falls off naturally with the vibration and avoiding secondary adhesion on the surface of the scraper 404.
