Description

Detailed explanation of the device

The present invention relates to an excavation blade replacement structure of a bucket for slope preparation work, which is attached to the tip of a boom of a hydraulic excavator and is used in the excavation process of slope preparation work.

Conventionally, the bucket for slope creation is equipped with excavation blades in the front and rear for the purpose of excavating earth and sand, and the slope on which the slope is formed is scraped up from below, and conversely, the slope is scraped down from above. In addition, there is work such as compacting the slope as a related work process.

In addition, based on information technology and location information by using GPS, excavation of slopes such as roads is input in advance, and slopes are created according to the program instructions.

However, the excavation blades provided before and after the slope preparation bucket are used under harsh conditions due to the various conditions of earth and sand on the slope, so the excavation blade wears out quickly, and when using information technology and GPS, front excavation The wear of the blade and the rear excavation blade part causes an error in the position information, and the front side excavation blade and the rear side excavation blade part are frequently updated due to the wear of the excavation blade, which affects the slope preparation work efficiency. Is coming out.

Various proposals have been made to solve the above-mentioned problems in the slope preparation work. For example, the replacement blade structure of the front excavation blade of the slope preparation work bucket of Practical New Design Registration No. 3106276 is a versatile method. Although it is widely used for the purpose of surface preparation work, the excavation blade provided on the front side of the bucket has been changed to a structure that facilitates attachment and detachment with bolts, but like the front excavation blade, the rear excavation blade is significantly worn out. When the rear excavation blade is replaced, a new welding operation for mounting the excavation blade has become a drawback such as a great hindrance to the slope preparation work process.

In order to solve the above-mentioned problems, as a technical means according to the present invention, in the front side excavation blade and the rear side excavation blade on the bottom surface of the bucket body, a method that enables the excavation blades that are frequently used and significantly worn out to be attached and detached by tightening bolts. It is characterized by.

In addition, the front side excavation blade and the rear side excavation blade adopt a fixing method with a plurality of bolts, and are characterized in that the excavation blade can be replaced in a short time.

According to the present invention, the front excavation blade of the slope work bucket is markedly worn by the work of scraping the slope from above and collecting the scraped earth and sand on the slope. While monitoring this front excavation blade, the excavation blade replacement work can be completed in a short time at any time. The rear excavation blade is relatively less worn, and although the frequency of replacement is low, the excavation blade can be replaced in a short time due to the simple fixing method using multiple bolts.

In addition, the excavation blade replacement work can be completed in a short time at will while monitoring the excavation blades on both sides, which are likely to occur on the front and rear excavation blades due to the scattered uneven wear condition by the workers. Can be done.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In Fig. 1, the entire side surface of the bucket X for slope preparation work according to the present invention is shown on the hydraulic excavator Y according to the present invention.

In addition, Fig. 2 is a side view of the hydraulic excavator Y, which is devised and excavates earth and sand with the slope preparation work bucket by the rear excavation blade and the front excavation blade.

Further, the embodiment of the bucket X for slope preparation work according to the present invention will be described with reference to the drawings. FIG. 3 is a perspective view of the slope-building work bucket X according to the present invention, showing a perspective view from the front pocket portion 1, and is a front side of the slope-building work bucket X of the present invention. It is a perspective view and a skeleton bird's-eye view which show the mounting position of the excavation blade 11.

Further, FIG. 4 shows a perspective view and a skeleton bird's-eye view as seen from the rear pocket portion 2 of the slope-building work bucket X of the present invention, and after the slope-building work bucket X of the present invention. The mounting position of the side excavation blade 12 is shown.

The front excavation blade mounting structure according to the present invention will be described with reference to FIG. 5, as can be seen in the side view of the bucket for slope creation work, excavation of the excavation blade on the bottom surface of the front pocket portion 1 and the bottom surface of the rear pocket portion 2. As for the blade, the bucket body spare blade support portion 10 is welded and fixed to the bucket body X, and the spare blade type excavation blades 11 and 12 are attached to the bucket body spare blade support portion 10 with bolts to indicate a fixed state, and are detached. It has a structure that makes it easy.

As shown in FIG. 6, the front excavation blade 11 has a bucket body replacement blade support portion 10 mounted on the bottom surface and a front excavation blade located on the bottom surface when the front side pocket portion 1 is viewed from the front in the bucket body X. 11 is provided, and as shown in the lower part of FIG. 6, the rear side excavation blade 12 is shown, and the shape and support of the flat blade-shaped replacement blade type excavation blades 11 and 12 and the bucket body replacement blade support portion 10 for supporting and fixing them. The portion 10, the front and rear excavation blades 11 and 12, and the bolt tightening hole 21 are viewed from above.

While facilitating the replacement of the excavation blade, the flatness of the bottom surface of the bucket, which is a feature of the bucket for slope preparation work, is maintained, and the bottom surface of the bucket is secured to flatten the unevenness of the slope.

Since the replacement blade structure of the front side excavation blade and the rear side excavation blade of the bucket for slope preparation work in the present invention has a simple structure, even an inexperienced field worker can easily replace the excavation blade and is inexpensive. It is possible to surely acquire and maintain the quality of the slope at the slope construction site due to the high cost.
