[0002] Bucket is a structural product, which is composed of tooth seat plate, bottom plate, side plate, wall plate, ear plate, back plate, bucket ear plate, bucket ear sleeve, bucket teeth, tooth seat, guard plate or bucket angle and other parts. Therefore, welding is the most critical manufacturing process of bucket, and the welding quality directly affects the structural strength and service life of the bucket.

[0003] However, as the scope of use increases, the disadvantages of ordinary buckets are also highlighted: they cannot be adapted to all industrial and mining operations. Conventional buckets are well suited for ordinary soil, ditches, yellow sand and other operating objects, and their service life will not be lower than expected. However, for more complex industrial and mining operations, such as various mines, the use of conventional buckets is often lower than the expected lifespan. Because the operating conditions in mines are generally very harsh, and most of the operating objects are ores, the impact resistance and wear resistance of the bucket are a huge test, and the bucket is often overloaded, causing irreparable damage to the bucket.

DETAILED DESCRIPTION

[0022] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0023] The terms “top surface”, “bottom surface” and “underside” are based on the normal use state of the rock bucket and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0024] like Figure 1-3 As shown, a wear-resistant rock bucket comprises a bucket body 1 formed by a bottom plate 101 and two side plates 103, a bucket ear 104 is fixedly connected to the end of the bottom plate 101, a tooth seat plate 105 is fixedly connected to the front end of the bottom plate 101, a plurality of bucket teeth 106 are arranged on the tooth seat plate 105, a wear-resistant strip 201 is arranged on the bottom plate 101, the wear-resistant strip 201 is detachably connected to the bottom plate 101 through a connecting piece, an elastic buffer pad 203 is arranged between the wear-resistant strip 201 and the bottom plate 101, and a reinforcing plate 107 is fixedly connected to the connection between the bottom plate 101, the side plate 103 and the tooth seat plate 105.

[0025] The rock bucket is usually installed on an excavator and is suitable for rock excavation. When in use, the wear-resistant strips 201 arranged on the bottom plate 101 can block the contact between the rock and the bottom plate 101, thereby reducing the wear rate of the bottom plate 101 and extending the service life of the rock bucket; the arrangement of the connecting piece can realize the disassembly and assembly between the wear-resistant strips 201 and the bottom plate 101, so that when the wear-resistant strips 201 are seriously worn, the wear-resistant strips 201 can be removed and replaced separately without replacing the entire rock bucket, which can reduce the use cost of the rock bucket, and the rock bucket after replacing the wear-resistant strips 201 can restore its wear resistance, thereby improving the overall use time of the rock bucket and extending its service life; the buffer pad 203 can be a rubber pad, The setting of the buffer pad 203 can absorb the impact energy generated by the collision between the rock bucket and the rock during the excavation process, thereby reducing the impact force on the rock bucket, and further extending the service life of the rock bucket and reducing the failure rate of the rock bucket; during the use of the rock bucket, the bucket teeth 106 are in contact with the rocks most frequently. In order to improve the stability of the bucket teeth 106, a reinforcement plate 107 is provided. The reinforcement plate 107 is fixed between the tooth seat plate 105, the bottom plate 101 and the side plate 103, and is used to improve the connection strength of the three, and at the same time cover the welds at the connection between the three, thereby reducing the wear at the connection between the three, so as to improve the stability of the tooth seat plate 105, and further improve the stability of the bucket teeth 106, and at the same time extend the service life of the rock bucket.

[0026] A further improvement is, Figure 4-6 As shown, multiple groups of wear-resistant strips 201 are arranged in pairs, and the two wear-resistant strips 201 in the same group are respectively located on both sides of the bottom plate 101, and are detachably connected to the bottom plate 101 through a connecting piece. Since both the outer side and the inner side of the bottom plate 101 frequently contact with rocks, the wear-resistant strips 201 are arranged on both the inner side and the outer side of the bottom plate 101, which can effectively reduce the wear of the bottom plate 101 and extend the service life of the rock bucket.

[0027] A further improvement is, Figure 5 and 6As shown, the connecting piece includes a stud 204 and a threaded sleeve 202 that are threadedly matched with each other, the ends of the stud 204 and the threaded sleeve 202 are fixedly connected to the limit block 206, the base plate 101 is provided with a mounting hole 102, the wear-resistant strip 201 is provided with a connecting hole 2011, and the threaded sleeve 202 is slidably arranged inside the mounting hole 102 and the connecting hole 2011. There are multiple connecting holes 2011 evenly spaced along the length direction on the wear-resistant strip 201, and the number of mounting holes 102 on the base plate 101 is the same as the connecting holes 2011 and corresponds one to one. When installing the wear-resistant strip 201, the two wear-resistant strips 201 are placed on both sides of the base plate 101 respectively, and buffer pads 203 are arranged between the two wear-resistant strips 201 and the base plate 101, and then the threaded sleeve 202 and the stud 204 are respectively inserted into the connecting holes 2011 of the two wear-resistant strips 201 until the threaded sleeve 202 and the stud 204 are butt-jointed, and then the stud 204 is screwed into the threaded sleeve 202 to complete the connection between the two, and under the action of the two limit blocks 206, the wear-resistant strips 201 are respectively pressed against the outside of the two wear-resistant strips 201, thereby completing the fixing and installation of the wear-resistant strip 201 on the base plate 101. When the wear strip 201 needs to be removed, the wear strip 201 can be moved toward the bottom plate 101 by squeezing the wear strip 201, thereby compressing the buffer pad 203 to reduce the mutual squeezing force between the threads of the threaded sleeve 202 and the stud 204, thereby facilitating the loosening of the threaded sleeve 202 and the stud 204 and improving the convenience of disassembling the wear strip 201.

[0028] A further improvement is, Figure 6 As shown, the connection hole 2011 is a countersunk hole, and the limit block 206 is located inside the connection hole 2011. The setting of the countersunk hole can accommodate the limit block 206 inside, thereby reducing the probability of contact between the limit block 206 and the rock, reducing the wear of the limit block 206, and then ensuring the stability of the installation of the wear-resistant strip 201. The setting of the limit block 206 is also conducive to rotating the stud 204 or the threaded sleeve 202, thereby improving the convenience of disassembly and assembly of the wear-resistant strip 201.

[0029] A further improvement is, Figure 4-6 As shown, an elastic member is further provided between the wear-resistant strip 201 and the bottom plate 101; the elastic member is a disc spring 205, and the threaded sleeve 202 is provided through the disc spring 205. The disc spring 205 is combined with the buffer pad 203 to achieve a mutually redundant setting, thereby improving the buffering effect of the wear-resistant strip 201 and improving the stability of the rock bucket.

[0030] A further improvement is, Figure 5 and 6 As shown, the side of the buffer pad 203 adjacent to the wear strip 201 is provided with a notch 2032 matching the wear strip 201, and the buffer pad 203 is also provided with a limiting hole 2031 for the threaded sleeve 202 to pass through, and the elastic member is located inside the limiting hole 2031. The setting of the notch 2032 can realize the mutual limitation between the buffer pad 203 and the wear strip 201, improve the stability of the connection between the two, and the buffer pad 203 can protect the edges around the wear strip 201 to slow down the wear speed of the wear strip 201; and the buffer pad 203 can also completely fill the gap between the wear strip 201 and the bottom plate 101, preventing small stones from entering and causing additional wear to the wear strip 201 and the bottom plate 101, thereby extending the service life of the rock bucket; the setting of the limiting hole 2032 is used to accommodate the disc spring 205, which can protect the disc spring 205, prevent the disc spring 205 from contacting with stones, and improve the reliability of the disc spring 205.

[0031] A further improvement is, Figure 1 , 2 As shown in FIG. 6 , the wear-resistant strips 201 extend along the width direction of the bucket body 1, and the wear-resistant strips 201 are evenly spaced, and the sides of the wear-resistant strips 201 facing away from the bottom plate 101 are chamfered in the circumferential direction. The chamfers can increase the intervals between the wear-resistant strips 201 and reduce the probability of rocks getting stuck between two adjacent wear-resistant strips 201.
