Abstract
Description
Technical Field
[0001] The utility model relates to the field of excavators, in particular to an excavator frame. Background Art
[0002] The lower frame of the excavator is an important load-bearing component of the excavator, which directly affects the overall performance and working stability of the excavator. Figure 1 As shown, it is composed of a frame body and a connecting seat. The problem with this technical solution is that the existing excavator frame lacks an impurity cleaning mechanism, which easily leads to the accumulation of sand, gravel, soil or other impurities on the frame during the excavation process of the excavator. As the use time increases, the impurities continue to accumulate and pile up, and constantly contact and rub against the rotating upper frame, which generates noise and easily causes the upper frame to rotate unsmoothly, affecting work efficiency. Utility Model Content
[0003] The purpose of the utility model is to solve the following problems existing in the prior art: the existing excavator frame lacks an impurity cleaning mechanism, which easily causes sand, gravel, soil or other impurities to accumulate on the frame during the excavation process of the excavator. As the use time increases, the impurities continue to accumulate and pile up, and constantly contact and rub against the rotating upper frame, which generates noise and easily causes the upper frame to rotate unsmoothly, affecting work efficiency.
[0004] In order to solve the problems existing in the prior art, the utility model provides an excavator frame, including a frame body and a connecting seat, a connecting seat is provided on the top of the frame body, a mounting seat is provided on the periphery of the connecting seat, a bearing seat is provided on the inner side of the mounting seat, and a scraper is provided on the bottom of the bearing seat.
[0005] Furthermore, a fixing rod is provided on the top of the bearing seat, and a fixing seat is provided on the top of the fixing rod. The fixing rod is connected to the upper frame through the fixing seat and the fixing bolt, and when the upper frame rotates, the movable bearing in the bearing seat is driven to rotate with it through the fixing rod.
[0006] Furthermore, a fixing bolt is provided inside the fixing seat, and the fixing rod is connected to the bottom of the roof frame through the fixing seat and the fixing bolt. After the fixing rod is connected to the upper frame through the fixing seat and the fixing bolt, when the upper frame rotates, the movable bearing in the bearing seat is driven to rotate along with it through the fixing rod.
[0007] Furthermore, a movable bearing is provided inside the bearing seat, and the top of the scraper is connected to the movable bearing through a connecting rod. When the upper frame of the excavator rotates, the movable bearing in the bearing seat is driven to rotate by the fixed rod fixedly connected to the upper frame, and the rotation of the movable bearing drives the scraper connected to the bottom through the connecting rod to rotate.
[0008] Furthermore, there are three groups of scrapers, one of which is a hard-bristle scraper. The rotating scraper can scrape away impurities such as sand, gravel and soil accumulated on the frame body, and one group of hard-bristle scrapers can be used to brush away stubborn impurities, thereby completing the impurity cleaning work.
[0009] Furthermore, the inner side of the mounting seat is connected to the periphery of the connecting seat through a sleeve snap ring. The mounting seat and the periphery of the connecting seat can be connected through the sleeve snap ring.
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] When the upper frame of the excavator of the utility model rotates and runs, the movable bearing in the bearing seat is driven to rotate by the fixed rod fixedly connected to the upper frame. The rotation of the movable bearing drives the scraper connected to the bottom through the connecting rod to rotate. The rotating scraper can scrape away impurities of sand, gravel and soil accumulated on the frame body. In conjunction with one set of hard-bristle scrapers, more stubborn impurities can be brushed, thereby completing the impurity cleaning work, solving the problem of existing impurities such as sand, gravel and soil accumulating on the frame body, causing equipment to generate noise and run unsmoothly, thereby increasing the practicality of the device.
