Description

Technical Field

[0001] The utility model relates to the field of engineering machinery, and in particular to a novel wear-resistant plate mounting structure. Background Art

[0002] At present, wear-resistant plates are installed on loader buckets with low-density and large bucket capacity to improve the wear resistance of the bucket, extend the service life of the bucket, and improve work efficiency. Several wear-resistant plates are placed close to the bottom of the main blade to protect the main blade from wear when shoveling materials. When the wear-resistant plates are worn to a certain extent, they need to be replaced. In this way, only the wear-resistant plates need to be replaced regularly, thereby protecting the bucket and greatly reducing the cost of using the bucket. There are currently many types of wear-resistant plate structures, including fixed, adjustable, and electromagnetic connection types. For example, the electromagnetic connection bucket wear-resistant plate structure of CN105040772A is parallel to the main blade and attached to the bottom. When shoveling materials, it can only protect the bottom of the main blade from wear. During long-term operation, the front of the main blade will still show a certain degree of wear, thereby reducing work efficiency and shortening the service life of the bucket. When the wear is severe, the bucket needs to be replaced, which increases the cost of using the loader bucket and causes a great waste of the company's operating costs. Summary of the Invention

[0003] The purpose of this utility model is to provide a new wear-resistant plate mounting structure, which adds a cutter head protection groove between the bottom guard plate and the side guard plate to protect the bottom of the main cutter plate while protecting the front end of the main cutter plate from wear, thereby better protecting the main cutter plate, extending the service life of the bucket, and reducing the cost of use.

[0004] The utility model is realized through the following technical solutions:

[0005] A new type of wear-resistant plate mounting structure includes a wear-resistant plate and a main blade plate. The wear-resistant plates each include a bottom guard plate and a side guard plate. A blade protection groove is provided between the bottom guard plate and the side guard plate. The main blade plate is mounted on the corresponding bottom guard plate through a fixing part, and the blade at the end of the main blade plate is located in the blade protection groove.

[0006] Furthermore, the fixing parts include bolts and nuts, countersunk holes are opened on the bottom guard plate, and through holes are opened on the main blade plate. The countersunk holes correspond to the through holes. After the bolts pass through the countersunk holes and the through holes, they are fastened by nuts and washers.

[0007] Furthermore, the side guard plate includes a front end portion, an oblique portion and an upper end portion, the front end portion is located in front of the wear-resistant plate, the oblique portion connects the front end portion and the upper end portion respectively, and a blade protection groove is opened on the inner side of the oblique portion and the upper end portion, and the oblique portion and the upper end portion completely wrap the blade at the end of the main blade plate, thereby playing a good protective role.

[0008] Furthermore, the front end portion is a vertical end face, the inclined portion is an inclined surface, and the top of the upper end portion is a horizontal surface. The structural shapes of the vertical end face, the inclined surface and the horizontal surface are the same as the structural shape of the blade head at the end of the main blade plate, which can provide better protection.

[0009] Furthermore, the number of the wear-resistant plates installed is 3, and the 3 wear-resistant plates are installed on the main blade.

[0010] Furthermore, the number of the wear-resistant plates installed is 7, and the 7 wear-resistant plates are installed on the main blade.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. By adding a cutter head protection groove between the bottom guard plate and the side guard plate, this semi-enclosed structure protects the bottom of the main cutting plate while protecting the front end of the main cutting plate from wear, thereby better protecting the main cutting plate.

[0013] 2. After long-term wear and tear, only the wear-resistant plate needs to be replaced to extend the service life of the bucket, improve work efficiency and reduce the cost of using the bucket. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figure 1 As shown, Example 1, a novel wear-resistant plate mounting structure, includes a wear-resistant plate 1 and a main blade 5. Each wear-resistant plate 1 includes a bottom guard plate 101 and a side guard plate 102. The bottom guard plate 101 and the side guard plate 102 are fixedly connected and preferably cast as a single piece. A cutting head protection groove 6 is provided between the bottom guard plate 101 and the side guard plate 102. The main blade 5 is mounted on the corresponding bottom guard plate 101 via a fixing member, and the cutting head at the end of the main blade 5 is located in the cutting head protection groove 6.

The structural shapes of the vertical end face, the inclined surface and the horizontal surface are the same as the structural shape of the cutting head at the end of the main cutting plate 5, which can play a better protective role; the number of installed wear-resistant plates 1 is 3, and 3 wear-resistant plates 1 are installed on the main cutting plate 5; the number of installed wear-resistant plates 1 is 7, and 7 wear-resistant plates 1 are installed on the main cutting plate 5, and the rest is the same as Example 1.

[0020] like Figure 2 As shown, wear-resistant plates 1 are installed separately on the main blade plate 5. Such wear-resistant plates 1 are easier to process and more durable. Two rows of countersunk holes are provided at the horizontal mounting point on the wear-resistant plate 1, and corresponding through holes are provided on the main blade plate 5. The wear-resistant plate 1 and the main blade plate 5 are connected and fixed by bolts 3, washers 4, and nuts 2. When the bucket is working, the wear-resistant plate 1 forms a semi-enclosed structure around the main blade plate 5, thereby reducing wear on the main blade plate 5. After a long period of operation, when the wear-resistant plate 1 wears to a certain extent, it only needs to be replaced without damaging the main blade plate 5, thereby extending the service life of the bucket and reducing costs.
