Description

Technical Field

[0001] The invention relates to the technical field of loaders, and in particular to a bucket of an open-pit coal mine wheel loader. Background Art

[0002] Open-pit coal mine wheel loader is a key equipment used in open-pit coal mining. Its bucket plays an important role. The bucket is the loading working device at the front end of the loader. The design background of the bucket is derived from the demand for efficient loading in coal mining. In traditional open-pit coal mining operations, manual loading has many disadvantages, such as high labor intensity, low operating efficiency, and poor working environment. In order to improve the efficiency and safety of mine loading operations, wheel loaders and their buckets have been developed. In order to ensure the working efficiency and safety of the bucket, its important components are usually made of wear-resistant materials and have excellent strength structural design to cope with long-term and high-intensity loading work. The bucket of the open-pit coal mine wheel loader, as an important loading working device, provides strong technical support for coal mining operations through optimized design in terms of improving loading efficiency, improving operating safety, and adapting to the site environment.

[0003] After searching, the Chinese patent number CN214657319U discloses a bucket of an open-pit coal mine wheel loader, including a bucket body, a connecting arm, a first connecting seat, a connecting plate, a first hydraulic rod, a second connecting seat, a third connecting seat, a second hydraulic rod, a rotating arm, a T-shaped rod, a connecting rod, a fourth connecting seat and a protective device. The utility model sets a protective device through the upper end of the bucket body. The protective plate is hit by an external force, and the protective plate rotates with the rotating rod and the fixed plate frame. The support plate plays a supporting role, and then the slide tube slides outside the slide rod seat under the force, and presses the first spring, thereby removing most of the impact force. At the same time, the second spring also plays an auxiliary buffering role between the first connecting plate and the second connecting plate, thereby playing a role in protecting the bucket, protecting the bucket from being easily damaged, ensuring the normal efficiency of the shoveling and digging operation, and reducing the cost of the device. Compared with the prior art, the Chinese patent number CN214657319U solves the problem that the existing bucket may be hit by coal ore during shoveling, which may cause damage to the bucket part, thereby indirectly affecting the efficiency of the shoveling operation and increasing the cost of the device.

[0004] However, in actual use of the above device, the loader unloads coal by relying on a hydraulic rod to drive the bucket to flip and let the coal fall freely, which is time-consuming and has insufficient unloading efficiency. In addition, there is a probability that the coal will get stuck in the bucket during the falling process, resulting in the inability to completely load and unload the coal, affecting the next loading amount. Therefore, a bucket for an open-pit coal mine wheel loader is proposed. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art that the loader unloads coal by relying on a hydraulic rod to drive the bucket to flip and let the coal fall freely, which is time-consuming and has insufficient unloading efficiency. In addition, there is a probability that the coal will get stuck in the bucket during the falling process, resulting in the inability to completely load and unload the coal, affecting the next loading amount. A bucket for an open-pit coal mine wheel loader is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A bucket of an open-pit coal mine wheel loader comprises a bucket, a bucket having shovel teeth arranged outside the bucket, an auxiliary unloading mechanism arranged outside the bucket, the auxiliary unloading mechanism comprising two transmission housings arranged outside a protective housing, a transmission assembly arranged inside the transmission housing, and a push plate arranged inside the bucket can be driven to move by the transmission assembly, so that the goods loaded and unloaded inside the bucket can be pushed out, and during the pushing process, the push plate can also clean the coal remaining on the inner wall of the bucket;

[0008] The outside of the bucket is rotatably connected to a connecting arm, and the outside of the connecting arm is provided with a cleaning mechanism. The cleaning mechanism includes a vibrating shell arranged on the outside of the connecting arm, and a beating assembly is arranged inside the vibrating shell. The beating assembly can drive the beating hammer arranged outside the vibrating shell to reciprocate, thereby quickly beating the bucket, causing the bucket to vibrate and shaking off the coal slag remaining in the bucket.

[0009] The above technical solution further includes:

[0010] The transmission assembly comprises a third motor arranged inside the transmission housing, a worm is arranged at an external output end of the third motor, and the worm is externally rotatably connected to the transmission housing.

[0011] The outside of the worm is meshedly connected with a worm wheel, the outside of the worm wheel is rotatably connected with a transmission housing, the outside of the worm wheel is fixedly connected with a third gear, and the outside of the third gear is meshedly connected with a transmission member.

[0012] A transmission slide groove is arranged inside the transmission housing, the transmission slide groove is slidably connected to the transmission member, and a push plate is fixedly connected to the outside of the transmission member.

[0013] The beating assembly includes a second motor arranged inside the vibration shell, a first transmission wheel is arranged at the external output end of the second motor, the first transmission wheel is externally rotatably connected to the vibration shell, the first transmission wheel is externally transmission-connected to a transmission belt, the transmission belt is externally transmission-connected to a second transmission wheel, and the second transmission wheel is externally rotatably connected to the vibration shell.

[0014] The second transmission wheel is fixedly connected to an eccentric shaft on the outside, the eccentric shaft is rotatably connected to a connecting piece on the outside, and the connecting piece is rotatably connected to a beating hammer on the outside.

[0015] The connecting arm is externally rotatably connected to a hydraulic rod, the hydraulic rod is externally rotatably connected to a connecting rod, the connecting rod is externally rotatably connected to a connecting arm, the connecting rod is externally rotatably connected to another transmission rod, and the transmission rod is externally rotatably connected to a bucket.

[0016] A protective shell is provided outside the bucket, a first motor is provided outside the protective shell, a first gear is provided at the external output end of the first motor, a second gear is meshedly connected to the outside of the first gear, a rotating shaft is fixedly connected to the outside of the second gear, and the protective shell is rotatably connected to the outside of the rotating shaft.

[0017] The outside of the rotating shaft is fixedly connected with a connecting plate, the outside of the connecting plate is fixedly connected with a protective plate, the protective plate is an arc-shaped structure, a telescopic rod is arranged outside the protective plate, a bucket is connected to the side of the telescopic rod away from the protective plate, and a shock-absorbing spring is arranged outside the telescopic rod.

[0018] The present invention has the following beneficial effects:

[0019] 1. In the present invention, the bucket can be driven to flip through the hydraulic rod arranged outside the connecting arm, so that the coal in the bucket can fall freely. During the bucket flipping process, the push plate can be driven to move through the transmission assembly arranged inside the transmission housing. The movement of the push plate can push the coal in the bucket out, thereby improving the loading efficiency of the coal. Moreover, during the movement of the push plate, the coal slag remaining on the side wall of the bucket can be cleaned, which is convenient and effective. During the auxiliary loading process of the push plate, the beating assembly arranged inside the vibration housing can drive the beating hammer arranged outside to perform reciprocating motion, thereby quickly beating the bucket, causing the bucket to vibrate and shaking off the coal slag remaining in the bucket, which can effectively prevent the coal slag from getting stuck in the bucket when falling and affecting the next loading.

[0020] 2. In the present invention, during the operation of the loader, the first motor arranged outside the protective shell can drive the protective plate to rotate, so that the protective plate can extend to shield the tail of the bucket. When the coal falls, the arc-shaped protective plate can effectively disperse the impact, thereby greatly reducing the initial impact. The shock-absorbing spring arranged under the protective plate can convert the impact on the protective plate into elastic potential energy through elastic deformation, thereby cushioning the protective plate, weakening the kinetic energy generated by the coal falling, protecting the bucket from being easily damaged, and increasing the service life of the bucket.
