AI Technical Summary
When the excavator works in an environment with lots of soil, the soil accumulated on the track beam will dry and cause difficulty or failure to rotate, resulting in abnormal wear and damage. The existing technology requires manual cleaning of soil regularly, which is time-consuming and labor-intensive, and lacks an automatic mud scraping mechanism.
An oscillation mud scraping mechanism is designed to use the inertial force generated by swinging up and down during the operation of the track to impact the power arm and drive the swing bracket to swing around the axis, so as to realize the oscillation and agitation of the soil on the track beam, so that the soil can slide down easily.
No additional power is required, and the inertial force of the track's own weight is used to achieve oscillation and clear mud, avoiding the problem of cleaning difficulties after the soil is dried into pieces, and it is more stable in use and reducing the impact on the guide wheel and support sprocket during the track operation.

[0025] like Figure 1 , Figure 3 , Figure 4 As shown, an oscillating mud scraping mechanism is mainly used in crawlers, including a support 4 and a swing bracket 2; the support 4 is fixed on the top surface of the crawler beam 5; the swing bracket 2 has a swing arm extending along the length direction of the crawler beam 5 and a power arm fixed in the middle area of the swing arm; the connection between the swing arm and the power arm is hinged with the support 4, and the top of the power arm extends to the crawler, and the inertial force generated when the crawler swings up and down during operation is used to provide power to hit the power arm, thereby driving the swing bracket 2 to swing around the hinge point, thereby oscillating and stirring the mud accumulated on the crawler beam 5.
[0026] The specific structure of the above-mentioned power arm is further described below.
[0027] like Figure 1 As shown, the power arm includes a rigid component and a rotating component inclined upward; the bottom of the rigid component is connected to the swing arm; the rotating component is installed on the top of the rigid component to contact with the crawler track and convert the sliding friction between the two into rolling friction.
[0028] Further solutions, such as Figure 1 As shown, the upwardly inclined rigid component consists of an oblique link 2-1 and a mounting shaft fixed at the top end of the oblique link 2-1 and with its axis perpendicular to the running direction of the track; the rotating component is at least one roller 1, which is coaxially mounted on the mounting shaft to form a coaxial rotating fit.
[0029] The specific structure of the above-mentioned swing arm is further described below.
[0030] like Figure 1As shown, the swing arm includes a horizontal rod, a rotating drum 2-3 and a plurality of scraper strips 2-5 arranged in parallel at predetermined intervals in the same plane; the horizontal rod is arranged above the track beam 5, and the horizontal rod extends along the length direction of the track beam 5; the rotating drum 2-3 is fixed in the middle area of the horizontal rod, and the axis of the rotating drum 2-3 is perpendicular to the running direction of the crawler track; the two axial end faces of the rotating drum 2-3 are each hinged to the support 4 through a pin shaft 3; a plurality of scraper strips 2-5 are fixed on the horizontal rod and swing with the horizontal rod.
[0031] It should be noted that the horizontal rod is a two-section structure, namely, it is composed of a left horizontal rod 2-2 and a right horizontal rod 2-4 in the accompanying drawings.
[0032] Further solutions, such as Figure 1 As shown, the scraper strip 2-5 is fixed on the left horizontal rod 2-2 and the right horizontal rod 2-4 in an inclined manner with its inner end higher than the outer end. The inclined scraper strip 2-5 is used to adapt to the inclined top surface of the track beam 5, and is used to slide the mud accumulated on the track beam 5 to the outside of the track beam 5.

[0034] like Figure 3 , Figure 4 As shown, after the crawler hits the power arm, the power arm drives the swing arm to swing around the hinge, so that one end of the swing arm falls and the other end rises; a reset component is installed between the rising end of the swing arm and the top surface of the crawler beam, which is used to quickly pull back the rising swing arm, thereby accelerating the swing frequency of the swing bracket.
[0035] Further solutions, such as Figure 3 , Figure 4 As shown, the reset component is composed of a tension spring 6 and a tension spring seat 7. The tension spring seat 7 is fixed on the track beam 5, and the tension spring 6 is connected between the tension spring seat 7 and the swing arm.
