UTILITY MODEL CONTENTS

[0003] In view of the above technical problem, the utility model provides an excavator fixed base material automatic cleaning device to solve the problem of time-consuming and laborious cleaning after the top surface of the walking support of lower car body of excavator is accumulated with material.

[0004] In order to realize the above purpose, the technical scheme of the utility model is as follows:

[0005] An excavator fixed base material automatic cleaning device, comprising a fixed base, the fixed base is installed at the bottom of the rotary base of the excavator, two symmetrical scraper steel frames are installed on the two sides of the fixed base, rubber plates are installed on the outer sides of the scraper steel frames through fasteners, and the bottom of the rubber plate is attached to the top surface of the walking support of the lower car body of the excavator.

[0006] Further, the bottom end of the scraper steel frame is outwardly inclined, and the structure of the rubber plate is adapted to the structure of the outer side of the scraper steel frame.

[0007] Further, the included angle between the bottom ends of the two scraper steel frames is 30°.

[0008] Compared with the prior art, the utility model has the beneficial effects that:

[0009] 1、In the normal operation process of excavator, the rotary base drives the fixed base and the scraper steel frame and rubber plate connected therewith to rotate synchronously, which can automatically and continuously clean the material on the top surface of the walking support of the lower car body, without the need to stop the machine and arrange personnel to clean, greatly improving the cleaning efficiency, saving labor cost and time cost, ensuring that the excavator can operate continuously for a long time, significantly improving the continuity and smoothness of the overall operation, effectively reducing the downtime caused by cleaning material, thereby improving the effective working time and production efficiency of the excavator;

[0010] 2. The unique design of the outwardly inclined bottom end of the scraper steel frame and the 30° angle between the bottom ends of the two scraper steel frames, combined with the rubber plate perfectly matched with the structure on the outer side of the scraper steel frame, effectively expands the cleaning range, can more comprehensively and completely clean the materials in each corner of the top surface of the walking support of the lower vehicle body, avoids damage to the walking support caused by material accumulation, reduces the risk of equipment failure caused by residual materials, ensures the stable operation and good performance of the walking system of the excavator, prolongs the service life of the equipment, and reduces the equipment maintenance cost and downtime loss caused by failure.

[0014] To make the purpose, technical scheme and advantages of the utility model clearer and more intelligible, the utility model will be further described in detail below in combination with specific implementation manners and with reference to the drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0015] A device for automatically cleaning materials of a fixed base of an excavator, comprising a fixed base 5, the fixed base 5 is installed at the bottom of a rotary base 3 of an excavator in cooperation, two symmetrically installed scraper steel frames 2 are arranged on the two sides of the fixed base 5, a rubber plate 1 is installed on the outer side of the scraper steel frame 2 in cooperation through a fastener 4, and the bottom of the rubber plate 1 is attached to the top surface of a walking support of a lower vehicle body of the excavator. When the excavator is working, the rotary base 3 drives the fixed base 5, the scraper steel frame 2 and the rubber plate 1 to rotate, which can automatically clean the materials on the top surface of the walking support of the lower vehicle body synchronously without additional operation, does not affect the normal work of the excavator, and guarantees the continuity of work.

[0016] Further, the bottom end of the scraper steel frame 2 is outwardly inclined, and the structure of the rubber plate 1 is matched with the structure on the outer side of the scraper steel frame 2.

[0017] Further, the angle between the bottom ends of the two scraper steel frames 2 is 30°. The outwardly inclined bottom end of the scraper steel frame 2 and the 30° angle between the bottom ends of the two scraper steel frames 2, combined with the matched rubber plate 1, can expand the cleaning range and enhance the cleaning effect to more comprehensively clean the materials on the top surface of the walking support.

[0018] When working:

[0019] When the excavator starts working, the rotary base 3 at the bottom of the excavator starts rotating. During the working of the excavator, the rotary base 3 drives the fixed base 5 and the scraper steel frame 2 and the rubber plate 1 to rotate. The rubber plate 1 continuously sweeps on the top surface of the walking support under the drive of the rotary base 3, thereby scraping and cleaning the materials that may be accumulated on the top surface of the walking support, preventing the materials from being accumulated too much to affect the normal work of the excavator, ensuring that the excavator can still operate stably and efficiently under complex environment and harsh working conditions, effectively avoiding a series of problems such as corrosion and wear of parts caused by material accumulation, and protecting the work safety and service life of the excavator.

[0020] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
