Description

Technical Field

[0001] This utility model belongs to the field of bucket wheel machine technology, and in particular relates to a wear-resistant bucket for a bucket wheel machine. Background Technology

[0002] A bucket wheel excavator is a heavy-duty excavating device widely used in open-pit mines and large-scale earthmoving projects. It mainly consists of a traveling mechanism, frame, boom, and bucket wheel. The bucket wheel is the core component of the bucket wheel excavator, equipped with multiple excavating buckets for digging soil or ore from the ground.

[0003] For example, Chinese invention CN116654641B discloses an anti-sticking mechanism for a bucket wheel excavator bucket. By setting up cleaning components and transmission components, it can automatically push the first arc plate to move and clean the bucket body during the process of the turntable rotating and driving the bucket to feed. At the same time, by setting up a striking component, it can use the power of the turntable rotation to drive the first impact block to collide with the second impact block, causing the bucket body to vibrate and shake off the sticky coal, further increasing its cleaning effect.

[0004] However, after prolonged use, the buckets of existing bucket wheel excavators inevitably experience wear and tear. The bucket opening, which is directly involved in digging materials, suffers the most severe wear. Due to the large size of the buckets, disassembling and replacing them when they are worn out is very inconvenient, time-consuming, and labor-intensive, which also greatly affects the efficiency of the equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a wear-resistant bucket for a bucket wheel excavator. By detachably connecting wear-resistant kit A and wear-resistant kit B to the bottom wall and side wall of the bucket opening, the bucket opening can be protected by wear-resistant kit A and wear-resistant kit B, and can be easily replaced. This solves the problems of easy wear and inconvenience of overall disassembly and replacement of existing buckets.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a wear-resistant bucket for a bucket wheel excavator, comprising a bucket, wherein a wear-resistant component A is detachably connected to the bottom wall of the bucket opening, and wear-resistant components B are detachably connected to both side walls of the bucket opening; the wear-resistant component A has an installation groove A that matches the bottom wall of the bucket, and the wear-resistant component B has an installation groove B that matches the side walls of the bucket, and the lower surface of the wear-resistant component B is in contact with the upper surface of the wear-resistant component A.

[0008] As a preferred technical solution of this utility model, the lower surface of the wear-resistant kit A is fixedly connected with a plurality of connecting protrusions, and a groove is opened on the side of the connecting protrusions away from the hopper opening, and a threaded hole is opened on the inner wall of the groove; the outer wall of the hopper is fixedly connected with a fixing block that is adapted to the groove opening one by one, and the fixing block is opened with a stepped hole corresponding to the threaded hole, so as to install and fix the wear-resistant kit A by inserting a screw through the stepped hole and cooperating with the threaded hole.

[0009] As a preferred embodiment of this utility model, the connecting protrusion is wedge-shaped.

[0010] As a preferred technical solution of this utility model, a plurality of the connecting protrusions are evenly distributed along the length direction of the wear-resistant kit A.

[0011] As a preferred embodiment of this invention, the wear-resistant kit A has a digging blade A.

[0012] As a preferred embodiment of this utility model, the connection structure between the wear-resistant kit B and the hopper is the same as the connection structure between the wear-resistant kit A and the hopper.

[0013] As a preferred embodiment of this invention, the wear-resistant kit B has a digging blade B.

[0014] As a preferred technical solution of this utility model, the digging blades B of the two wear-resistant kits B are distributed in a figure-eight shape.

[0015] This utility model has the following beneficial effects:

[0016] This invention features a wear-resistant kit A detachably connected to the bottom wall of the hopper opening, and wear-resistant kits B detachably connected to both side walls of the hopper opening. The wear-resistant kits A and B protect the hopper opening, preventing wear. Compared to disassembling and replacing the entire hopper, disassembling and replacing the wear-resistant kits A and B is more convenient and faster, thus greatly improving the efficiency of the equipment.

[0030] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Please see Figure 1 and 3 As shown, this utility model is a wear-resistant bucket for a bucket wheel excavator, including a bucket 1. The bottom wall of the bucket opening of the bucket 1 is detachably connected to a wear-resistant kit A2, and both side walls of the bucket opening of the bucket 1 are detachably connected to wear-resistant kits B3. The wear-resistant kits A2 and B3 are used to protect the bucket opening of the bucket 1 and prevent wear from occurring.

[0033] Specifically, such as Figure 4 , 6 As shown in Figure 8, the wear-resistant kit A2 has a mounting groove A201 that fits the bottom wall of the hopper 1. Three connecting protrusions 202 are fixedly connected to the lower surface of the wear-resistant kit A2, and a countersink 203 is provided on the side of the connecting protrusions 202 away from the opening of the hopper 1. A threaded hole 204 is provided on the inner wall of the countersink 203. The connecting protrusions 202 and the wear-resistant kit A2 are an integral structure, and the three connecting protrusions 202 are evenly distributed along the length of the wear-resistant kit A2.

[0034] The outer wall of the hopper 1 is welded with a fixing block 101 that matches the settling trough opening 203, or the hopper 1 and the fixing block 101 are also an integral structure. The fixing block 101 has a stepped hole 102 corresponding to the threaded hole 204.

[0035] During installation, such as Figure 2 and 6 As shown, the bottom wall of hopper 1 is inserted into the mounting groove A201 of wear-resistant kit A2, and at this time, the fixing block 101 on the bottom wall of hopper 1 is inserted into the recess 203. Then, the screw passes through the stepped hole 102 and cooperates with the threaded hole 204. By tightening the screw, the wear-resistant kit A2 is installed and fixed.

[0036] During disassembly, only the screw structure needs to be removed, making overall disassembly and replacement more convenient. Meanwhile, the connecting protrusion 202 has a wedge-shaped structure, which causes the height of the connecting protrusion 202 to gradually increase in the direction away from the bucket opening, thereby helping to reduce the resistance encountered during excavation.

[0037] Furthermore, the fixing block 101 is connected to the side of the connecting protrusion 202 facing away from the opening of the hopper 1, which can effectively prevent the fixing block 101 and the screw from wearing out during the excavation process, thereby improving the overall reliability and service life.

[0038] In a preferred embodiment, the wear-resistant kit A2 has a digging blade A205, which can reduce the resistance encountered by the hopper 1 during digging and improve the ease of digging.

[0039] like Figure 5 , 7 As shown in Figure 9, the wear-resistant kit B3 has a mounting groove B301 that fits the side wall of the hopper 1, and the lower surface of the wear-resistant kit B3 is in contact with the upper surface of the wear-resistant kit A2. Similarly, the connection structure between the wear-resistant kit B3 and the hopper 1 is the same as the connection structure between the wear-resistant kit A2 and the hopper 1. That is, the wear-resistant kit B3 is also provided with a connecting protrusion 202, and the outer side wall of the hopper 1 is also provided with a fixing block 101 that cooperates with it.

[0040] In another preferred embodiment, the wear-resistant kit B3 has a digging blade B302, which serves the same function as the digging blade A205. Furthermore, the digging blades B302 of the two wear-resistant kits B3 are arranged in a V-shape, thereby effectively guiding the excavated material towards the interior of the hopper 1, which helps improve the overall digging efficiency.
