Problems solved by technology

[0007]The more sludge that cannot be scraped off, the less objects the grab can grab in the next grab, reducing the working efficiency of the grab machine
According to incomplete statistics, the mud scraping rate of the grab bucket in the prior art is only 70%. Due to poor mud scraping, the working efficiency of the grab bucket is low, the construction period is increased, and resources are wasted at the same time

Embodiment Construction

[0028] The core of the present invention is to provide a mud scraper for a grab, which has a high mud scraping rate, which is beneficial to improving the working efficiency of the grab and improving the construction progress. Another core of the present invention is to provide a grab bucket comprising the above mud scraper.

[0029] The basic concept of the present invention is: on the basis of the original static mud scraping device, install a dynamic mud scraping device that can slide along the extension direction of the static mud scraping device, so that the overall length of the mud scraper can be adjusted according to the opening degree of the grab body. It grows as it increases, and shortens as the closure of the grab body increases, so as to improve the mud scraping efficiency of the grab bucket and improve the working efficiency of the grab bucket without affecting the normal operation of the grab bucket body.

[0030] In order to enable those skilled in the art to be...

Abstract

The invention discloses a sludge scraper for a grab bucket, and the sludge scraper comprises a fixed mud scraper (2), a movable mud scraper (3) and a rigid connecting rod (5), wherein the fixed mud scraper (2) is fixed with a grab bucket bracket (6); the movable mud scraper (3) is connected with the fixed mud scraper (2) in a sliding mode; and one end of the rigid connecting rod (5) is hinged with a grab bucket body (4) of the grab bucket, and the other end is hinged with the movable mud scraper (2), so that the grab bucket body (4) drives the movable mud scraper (3) to slide relatively to the fixed mud scraper (2). The movable mud scraper (3) of the sludge scraper can slide in the extending direction of the fixed mud scraper (2), so that the overall length of the sludge scraper can increase as the opening degree of the grab bucket body (4) increases, and decrease as the closing degree of the grab bucket body (4) increases, thereby enhancing the mud scraping efficiency and the workingefficiency of the grab bucket without influencing the normal operation of the grab bucket body. The invention also discloses a grab bucket comprising the sludge scraper.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a mud scraper for a grab bucket. In addition, the present invention also relates to a grab bucket comprising the above mud scraper. Background technique [0002] Grabs are widely used in modern industry, especially modern construction industry. Among them, the underground diaphragm wall grab, as a deep foundation construction equipment that can meet high-efficiency and high-quality construction, is widely used in the deep foundation engineering construction of urban high-rise buildings. [0003] Please refer to figure 1 and figure 2 , figure 1 It is a structural schematic diagram of a typical grab bucket and mud scraper in the prior art; figure 2 for figure 1 Schematic diagram of the operation of the grab bucket and mud scraper shown. [0004] figure 1 The shown grab includes a grab support 11 and a grab body 12, wherein a mud scraper 13 is fixedly connect...
