Description

Technical Field

[0001] This utility model belongs to the field of excavator technology, specifically relating to an excavator bucket that can screen the size of stones. Background Technology

[0002] In road construction, in order to quickly separate large stones mixed in with sand and soil, a bucket with a screen is usually used for digging.

[0003] In the prior art, such as the Chinese utility model patent document with authorization announcement number CN215166037U, an excavator bucket that can screen the particle size of stones is disclosed. During the digging process, smaller sand particles are leaked out from the screen, while larger stone particles are intercepted by the screen, thus achieving the purpose of screening while digging. However, when it is necessary to dig fine particles, the entire bucket needs to be replaced, which is a relatively complicated process and takes a lot of time.

[0004] Therefore, it is necessary to design an excavator bucket that can screen stone particle size and is easy to adjust for fine particulate materials to solve the current technical problems. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the present invention provides an excavator bucket that can screen stone particle size and is easy to adjust for digging shovels used for fine particulate materials.

[0006] The technical solution of this utility model is as follows: an excavator bucket capable of screening stone particle size, comprising a bucket body, an ear plate provided on the outer side of one end of the bucket body, and bucket teeth evenly provided on the other end of the bucket body, an inner mesh plate and an outer mesh plate arranged parallel to each other inside the bucket body, a cavity provided between the inner mesh plate and the outer mesh plate, the two ends of the cavity being connected to the two sides of the bucket body respectively, a baffle slidably provided inside the cavity, and a locking mechanism provided on the bucket body for locking or releasing it between the baffle and the baffle.

[0007] The baffle is provided with a locking hole, and the locking mechanism has a locking bolt that is vertically slidably disposed on the outside of the bucket body corresponding to the locking hole.

[0008] A limiting ring is fixedly provided at one end of the locking bolt away from the baffle. A support cylinder is slidably fitted on the outer side of the limiting ring. One end of the support cylinder is fixedly provided on the outer side of the bucket body. A retaining ring is fixedly provided at one end of the support cylinder away from the bucket body. A spring is provided between the retaining ring and the limiting ring.

[0009] A pull rod is fixedly installed in the center on the side of the limiting ring opposite to the locking bolt, and a pull hole is opened on one side of the end of the pull rod along its radial direction.

[0010] The bucket teeth are detachably fixed to one end of the bucket body by bolts.

[0011] The bucket body has an inclined surface at one end where the bucket teeth are provided. The bucket teeth have a main body and a groove that matches the inclined surface. An upper fixing plate is provided on one side of the main body of the bucket teeth, and a lower fixing plate is provided on the other side of the main body of the bucket teeth. At least two bolts are provided on the upper fixing plate that penetrate the bucket body and are threadedly connected to the lower fixing plate.

[0012] A spring washer is fitted onto the bolt.

[0013] The beneficial effects of this utility model are:

[0014] (1) This utility model can screen the size of stones and is easy to adjust the shovel for fine particles. It does not require a complete replacement of the bucket and is easy to adjust to cope with different usage scenarios.

[0015] (2) The baffle can be removed from or reinstalled in the cavity. When it is necessary to screen the stones, the baffle is released by the locking mechanism and removed from the cavity. At this time, during the digging process, the smaller sand particles leak out from the inner and outer mesh plates, while the larger stones are intercepted in the digging process to achieve the purpose of screening.

[0016] (3) When it is necessary to dig out small particles of material, it is not necessary to replace the entire bucket. Just put the baffle back into the cavity and lock the baffle through the locking mechanism. At this time, the baffle blocks the inner and outer mesh plates and can dig out small particles of material. Attached Figure Description

[0025] like Figures 1 to 6 As shown, an excavator bucket capable of screening stone particle size includes a bucket body 1. An ear plate 6 is provided on the outer side of one end of the bucket body 1, and bucket teeth 5 are evenly distributed on the other end. An inner mesh plate 2 and an outer mesh plate 3 are arranged parallel to each other inside the bucket body 1. A cavity 7 is provided between the inner mesh plate 2 and the outer mesh plate 3. Both ends of the cavity 7 are connected to the two sides of the bucket body 1. A baffle 4 is slidably disposed inside the cavity 7. A locking mechanism 6 is provided on the bucket body 1 for locking or releasing the baffle 4. In this embodiment, the baffle 4 can be removed from or reinstalled in the cavity 7. When stone screening is required, the baffle 4 is released by the locking mechanism 6. When the baffle 4 is removed from the cavity 7, during the digging process, smaller sand particles leak out from the inner mesh plate 2 and the outer mesh plate 3, while larger stones are intercepted during digging, achieving the purpose of screening. When it is necessary to dig fine particles, it is not necessary to replace the entire bucket. Simply put the baffle 4 back into the cavity 7 and lock it through the locking mechanism 6. At this time, the baffle 4 blocks the inner mesh plate 2 and the outer mesh plate 3, enabling the digging of fine particles. It can screen the particle size of stones and is easy to adjust the digging tool for fine particles without replacing the entire bucket, making it easy to adjust to cope with different usage scenarios.

[0026] In some embodiments, the baffle 4 is provided with a locking hole 41, and the locking mechanism 6 has a locking bolt 61 that is vertically slidably disposed on the outside of the bucket body 1 corresponding to the locking hole 41. By controlling the movement of the locking bolt 61, its end can be inserted into the locking hole 41 or pulled out from the locking hole 41, thereby realizing the locking or releasing between the bucket body 1 and the baffle 4.

[0027] In some embodiments, a limiting ring 63 is fixedly provided on one end of the locking bolt 61 away from the baffle 4. A support cylinder 65 is slidably fitted on the outer side of the limiting ring 63. One end of the support cylinder 65 is fixedly provided on the outer side of the bucket body 1. A retaining ring 66 is fixedly provided on the other end of the support cylinder 65 away from the bucket body 1. A spring 64 is provided between the retaining ring 66 and the limiting ring 63. The spring 64 applies elastic force to the limiting ring 63. When the locking mechanism 6 locks the baffle 4, the elastic force of the spring 64 on the limiting ring 63 can keep the locking bolt 61 inserted into the locking hole 41 in a locked state.

[0028] In some embodiments, a pull rod 62 is fixedly provided on the side of the limiting ring 63 opposite to the locking bolt 61. A pull hole 67 is provided on one end of the pull rod 62 along its radial direction. The pull rod 62 can be easily pulled through the pull hole 67. The pull rod 62 can drive the locking bolt 61 to move, so that the locking bolt 61 can be pulled out from the locking hole 41, releasing the locking state of the baffle 4, so that the baffle 4 can be pulled out from the cavity 7.

[0029] In some embodiments, the bucket teeth 5 are detachably fixed to one end of the bucket body 1 by bolts 54, and the bucket teeth 5 can be replaced by removing the bolts 54, making it convenient to replace the bucket teeth 5 when they are worn.

[0030] In some embodiments, the bucket body 1 has a slope 11 at one end where the bucket teeth 5 are provided. The bucket teeth 5 have a bucket tooth body 51. The bucket tooth body 51 has a slot 52 that matches the slope 11. An upper fixing plate 53 is provided on one side of the bucket tooth body 51, and a lower fixing plate 55 is provided on the other side of the bucket tooth body 51. At least two bolts 54 are provided on the upper fixing plate 53 that penetrate the bucket body 1 and are threadedly connected to the lower fixing plate 55.

[0031] In some embodiments, a spring washer is fitted on the bolt 54. The elastic force of the spring washer provides a continuous force to the bolt 54, thereby increasing the friction between the bolt 54 and the internal threaded hole of the lower fixing plate 55, achieving a fastening effect.

[0032] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0033] The embodiments described above only illustrate some implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent.
