Description

Technical Field

[0001] This utility model relates to the technical field of bucket devices, specifically to a bucket device for a wheel loader with adaptive angle adjustment for mining conditions. Background Technology

[0002] The adaptive angle adjustment bucket device for mining working conditions is a key component of loaders used in complex working conditions such as mines. It can automatically or semi-automatically adjust the bucket angle according to different working environments and material characteristics to improve work efficiency and quality. When the ore is scooped up, it comes into close contact with the inner wall of the bucket. Due to the irregular shape and rough surface of the ore, as well as its own weight and friction, a considerable portion of the ore adheres tightly to the inner wall of the bucket during the unloading process. Even if the operator tilts the bucket to its maximum angle, the stubborn ore remains unmoved and firmly attached to the inside of the bucket. Similarly, when handling materials such as slag and soil, the stickiness of the slag and soil makes it very easy for them to form a thick layer on the inner wall of the bucket. After unloading, a large amount of slag and soil remains inside, which seriously affects the subsequent use of the bucket.

[0003] Therefore, an adaptive angle adjustment wheel loader bucket device for mining conditions is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a bucket device for a wheel loader with adaptive angle adjustment for mining conditions, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A mining working condition adaptive angle adjustable wheel loader bucket device includes a loader body and a bucket body, wherein a vibration mechanism is provided on the outer side of the bucket body; The vibration mechanism includes stabilizing plates, with guide rails fixedly connected between the stabilizing plates. A cam is rotatably connected to the outer side of the guide rails, with a connecting ring on the outer side of the cam. A rotating groove is opened inside the cam. A transmission rod is fixedly connected to the outer side of the guide rails, and a limit plate is fixedly connected to the outer side of the guide rails.

[0006] As a further optimization of this utility model, a buffer mechanism is provided on the outer side of the cam. The buffer mechanism includes a connecting plate, a nylon rod is movably engaged at the bottom of the connecting plate, a rubber plate is fixedly connected to the bottom of the nylon rod, and a shock-absorbing spring is sleeved on the nylon rod.

[0007] As a further optimization of this utility model, the stabilizing plates are fixedly and symmetrically distributed on the top of the bucket body, and the guide rails are fixedly connected to the outside of the bucket body through the stabilizing plates.

[0008] As a further optimization of this utility model, the cams are evenly distributed on the outer side of the guide rail, the connecting rings are symmetrically distributed on the outer side of the cams, and the connecting rings are rotatably connected to the outer side of the guide rail.

[0009] As a further optimization of this utility model, the transmission rods are evenly distributed on the outer side of the guide rail, and the end of the transmission rod away from the guide rail is rotatably connected to the inside of the rotating groove.

[0010] As a further optimization of this utility model, the number of limiting plates is the same as the number of cams, and the limiting plates are located on the outside of the cams.

[0011] As a further optimization of this utility model, the connecting plate is fixed and symmetrically distributed on the outside of the cam, and the nylon rod and the shock-absorbing spring are symmetrically distributed between the connecting plate and the rubber plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the vibration mechanism, through the linkage structure of "guide rail-cam-transmission rod", can generate stable vibration when the bucket is unloading. The transmission rod drives the cam to rotate around the guide rail along the rotating groove inside the cam. During the rotation, the connecting ring on the outer side of the cam further enhances the vibration transmission, which can effectively shake off the ore, slag and other materials adhering to the inner wall of the bucket. Compared with traditional buckets without vibration function, it can significantly reduce the amount of material residue, avoid increasing the load on the bucket due to repeated cleaning or residual material, and improve the efficiency of single operation and the service life of the equipment.

[0015] 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.

[0016] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0017] Please see Figures 1-6 This utility model provides a technical solution: The adaptive angle-adjustable wheel loader bucket device for mining conditions includes a loader body 1 and a bucket body 2, with a vibration mechanism 3 installed on the outer side of the bucket body 2. The vibration mechanism 3 includes a stabilizing plate 31, a guide rail 32 fixedly connected between the stabilizing plates 31, a cam 33 rotatably connected to the outer side of the guide rail 32, a connecting ring 34 provided on the outer side of the cam 33, a rotating groove 35 opened inside the cam 33, a transmission rod 36 fixedly connected to the outer side of the guide rail 32, and a limit plate 37 fixedly connected to the outer side of the guide rail 32.

[0018] It should be noted that: the stabilizing plate 31 is fixed and symmetrically distributed on the top of the bucket body 2; the guide rail 32 is fixedly connected to the outside of the bucket body 2 through the stabilizing plate 31; the cams 33 are evenly distributed on the outside of the guide rail 32; the connecting rings 34 are symmetrically distributed on the outside of the cams 33, and the connecting rings 34 are rotatably connected to the outside of the guide rail 32; the transmission rods 36 are evenly distributed on the outside of the guide rail 32, and the end of the transmission rod 36 away from the guide rail 32 is rotatably connected to the inside of the rotating groove 35; the number of limiting plates 37 is the same as the number of cams 33, and the limiting plates 37 are located on the outside of the cams 33.

[0019] Furthermore, in addition to its basic positioning function of being symmetrically fixed to the top of the bucket body 2, the stabilizing plate 31 is connected to the bucket body 2 using a dual fixing method of welding and bolt reinforcement. Initial fixing is achieved through submerged arc welding, and then holes are drilled at the four corners of the stabilizing plate 31, with high-strength bolts penetrating the reinforcing ribs of the bucket body 2. This prevents the stabilizing plate 31 from falling off due to high-frequency vibrations in the mine, ensuring the installation stability of the guide rail 32. Specifically: Cam 33 adopts an "eccentric" structure design with an eccentricity controlled at 5-8mm. When the transmission rod 36 drives it to rotate, it can generate a moderate vibration, which can shake off the sticky material and avoid deformation of the bucket body 2 due to excessive vibration. The connecting ring 34 is made of polytetrafluoroethylene and has a built-in ball bearing. It is sleeved on the outside of the guide rail 32. On the one hand, it rotates with cam 33 to enhance the vibration effect, and on the other hand, it reduces the direct friction between cam 33 and guide rail 32, reducing the wear rate of components.

[0020] As a further implementation of this solution, a buffer mechanism 4 is provided on the outer side of the cam 33. The buffer mechanism 4 includes a connecting plate 41, a nylon rod 42 is movably engaged at the bottom of the connecting plate 41, a rubber plate 43 is fixedly connected to the bottom of the nylon rod 42, and a shock-absorbing spring 44 is sleeved on the nylon rod 42.

[0021] It should be noted that the connecting plate 41 is fixed and symmetrically distributed on the outside of the cam 33, and the nylon rod 42 and the shock-absorbing spring 44 are symmetrically distributed between the connecting plate 41 and the rubber plate 43.

[0022] Furthermore, the rubber plate 43 is made of nitrile rubber with a thickness of 15-20mm and has a diamond-shaped anti-slip texture on the surface. On the one hand, when the bucket collides with the ore, the elastic deformation of the rubber initially absorbs the impact energy. On the other hand, the anti-slip texture can increase the friction with the ore, assist in loading materials, and reduce the slippage of materials in the bucket.

[0023] Specifically: Nylon rod 42 is made of MC nylon material, which has high strength and high toughness, with a compressive strength of over 80MPa, and can withstand the longitudinal pressure during bucket collision. Shock-absorbing spring 44 is made of 60Si2Mn spring steel, with a spring wire diameter of 8-12mm and an effective number of 5-8 coils. The stiffness coefficient has been precisely calculated. When subjected to an impact load of 500-1000N, the compression is controlled at 10-15mm, which can both buffer and quickly recover. The "symmetrical distribution" design of nylon rod 42 and shock-absorbing spring 44 makes the buffering force evenly distributed to cam 33 and bucket body 2, avoiding excessive local stress that could cause deformation of connecting plate 41 or cam 33.

[0024] Work process: First, the vibration mechanism 3 is based on the stabilizing plate 31. Since the stabilizing plate 31 is symmetrically fixed on the top of the bucket body 2, the guide rail 32 connected by the stabilizing plate 31 is stably installed on the outside of the bucket body 2. When the device is started, the transmission rods 36 evenly distributed on the outside of the guide rail 32 will drive the cam 33 to operate. The end of the transmission rod 36 away from the guide rail 32 rotates in the rotating groove 35 inside the cam 33, causing the cam 33 to rotate around the guide rail 32. The connecting rings 34 symmetrically arranged on the outside of the cam 33 and also rotatably connected to the guide rail 32 will further enhance the vibration effect as the cam 33 rotates. At the same time, the limiting plates 37 on the outside of the guide rail 32, which are the same number as the cam 33, will restrict the position of the cam 33 to prevent it from detaching from the guide rail 32 when rotating. Finally, the stable vibration is transmitted to the bucket body 2, which helps to shake off the material adhering to the inner wall when unloading. Meanwhile, the connecting plate 41 symmetrically fixed on the outer side of the cam 33 provides support for the buffer mechanism 4. When the bucket collides with hard ore or loads large pieces of material during mining operations, the rubber plate 43 in the buffer mechanism 4 first directly contacts the force, and then pushes the top-fixed nylon rod 42 to retract along the movable slot at the bottom of the connecting plate 41. At this time, the shock-absorbing spring 44 sleeved on the nylon rod 42 is compressed synchronously. Through the initial energy absorption of the rubber plate 43 and the elastic buffering of the shock-absorbing spring 44, the impact load is weakened together. Moreover, the symmetrical distribution of the nylon rod 42 and the shock-absorbing spring 44 can ensure that the buffer force is evenly transmitted and avoid local deformation. Thus, while ensuring the unloading efficiency, it can protect the bucket body 2 and the loader body 1, adapting to the complex working conditions of the mine.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
