Description

Technical Field

[0001] The utility model relates to the technical field of ore transportation, in particular to a high-strength mining bucket. Background Art

[0002] A mining truck is a heavy-duty dump truck used in open-pit mines to complete rock and earth stripping and ore transportation tasks. Mining trucks are mainly used for short-distance, heavy-load transportation tasks. They are often used in conjunction with large electric shovels or hydraulic shovels for loading, and travel back and forth between mining sites and unloading sites.

[0003] Currently, when ore is poured into the bucket, since there is no buffer layer or buffer mechanism inside the bucket, the ore directly collides with the metal surface of the bucket. This direct impact will cause wear and damage to the surface of the bucket, which will have an adverse effect on the overall structure and life of the bucket. Due to the lack of buffering and protection measures, the strength and durability of the bucket will be severely tested under the long-term impact and friction of the ore, which may cause deformation, cracking or damage to the bucket, thereby affecting its normal function and safety. Moreover, during the process of tilting the bucket to unload, due to the friction between the ore and the limitations of the internal structure of the bucket, some small pieces of ore are likely to remain inside the bucket, which will not only lead to waste of ore, but may also affect the reloading and transportation efficiency of the bucket. Utility Model Content

[0004] The purpose of the present utility model is to provide a high-strength mining truck bucket to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a high-strength mining bucket, comprising a bucket body mounted on a mining truck and a buffer plate disposed inside the bucket body, and further comprising:

[0022] The top of the first spring 3 is fixedly connected to the bottom of the buffer plate 2, and the buffer strip 4 is located between the first springs 3. The material of the buffer strip 4 is wear-resistant rubber. When the staff pours the ore into the truck body 1, the buffer plate 2 will squeeze the first spring 3 below, and the buffer plate 2 will be buffered by the first spring 3. As the buffer plate 2 continues to fall, the buffer plate 2 will also contact the surface of the buffer strip 4, and the buffer strip 4 will further buffer the buffer plate 2, thereby protecting the entire truck body 1 below.

[0023] The buffer plate 2 is arranged in a folded shape as a whole, and the buffer plate 2 is slidably connected to the inner wall of the truck bed body 1. When the staff pours the ore into the truck bed body 1, the buffer plate 2 is arranged to block the gap between the truck bed body 1 and the buffer plate 2, thereby preventing the ore from entering between the buffer plate 2 and the truck bed body 1 and causing damage to the surface of the truck bed body 1 and the buffer plate 2.

[0024] Guide blocks 13 are fixed on the front and rear sides of the bottom of the movable frame 7, and guide rails 14 are fixed on the front and rear sides above the truck body 1, and the guide blocks 13 are sleeved on the surface of the guide rails 14 and slidably connected with the guide rails 14. When the hydraulic rod 6 pushes the movable frame 7 to move left and right, the guide blocks 13 will also slide on the surface of the guide rails 14, and the movable frame 7 is guided by the guide blocks 13 to improve the stability of the movable frame 7 when it moves left and right, so that the pusher plate 9 can push out the remaining ore inside the truck body 1.

[0025] The pusher plate 9 is slidably connected to the surface of the fixed plate 8, and the bottom of the pusher plate 9 is inclined, and the surface of the bottom of the pusher plate 9 is in contact with the surface above the buffer plate 2 and is slidably connected to the buffer plate 2. As the movable frame 7 continues to move to the right, the pusher plate 9 can push out the remaining ore on the surface of the buffer plate 2. As the pusher plate 9 moves to the right, the pusher plate 9 will slide upward, and the telescopic rod 11 and the second spring 12 will shrink, so that the bottom of the pusher plate 9 is always in contact with the surface of the buffer plate 2, so as to push out all the remaining ore inside the bucket body 1.

[0026] Slide grooves 15 are provided on the front and rear sides of the right side surface of the fixed plate 8, and rollers 16 are embedded on the front and rear sides of the top of the push plate 9, and the rollers 16 are rotatably connected to the push plate 9. One side of the roller 16 is located inside the slide groove 15 and is rollingly connected to the inside of the slide groove 15. When the push plate 9 moves up and down, the roller 16 will roll inside the slide groove 15, and the push plate 9 is guided by the roller 16 to improve the stability of the push plate 9 when sliding up and down.

[0027] Working principle: When the bucket is transporting ore, the staff first pours the ore to be transported into the inside of the bucket body 1. At this time, the buffer plate 2 will come into contact with the ore, and the buffer plate 2 will cushion the fallen ore, thereby protecting the entire bucket body 1. After all the ore is poured into the inside of the bucket body 1, the staff can drive the mining truck to transport the ore. After transporting the ore to the unloading position, the staff controls the mining truck to move the bucket body 1, causing the bucket body 1 to tilt as a whole, and then pour out the ore inside the bucket body 1. At this time, the staff opens the hydraulic rods 6 on both sides, and then the hydraulic rods 6 push the movable frame 7 to move, and the push plate 9 will push out the small pieces of ore remaining inside the bucket body 1, thereby completing the unloading operation of the ore.

[0028] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
