[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example 1

[0023] Please see Figures 1 to 2 This utility model provides a technical solution: an earthmoving excavation device for construction engineering, including an excavator body 1, a bucket 4 installed at one end of the excavator body 1, a frame 2 installed at the bottom end of the excavator body 1, tracks 3 rotatably connected to both sides of the frame 2, two fixed frames 5 installed at the bottom end of the excavator body 1, a connecting plate 11 slidably connected to the surface of the fixed frame 5, two sets of limiting blocks 15 slidably connected to both ends of the connecting plate 11, the limiting blocks 15 being embedded in the surface of the fixed frame 5, two center rods 13 inserted into the surface of the connecting plate 11, and a scraper 6 fixedly connected to the bottom end of the two center rods 13, the scraper 6 being attached to the surface of the track 3;

[0024] A scraper 6 is installed on the surface of the track 3, which can scrape off the mud, sand and other debris attached to the surface of the track 3. Through the cooperation of the central rod 13 and the spring 19, the scraper 6 can always be in contact with the surface of the track 3, thereby improving the cleaning efficiency of the track 3.

[0025] By cooperating with the fixed frame 5, the sliding plate 12 and the connecting plate 11, the position of the scraper 6 can be adjusted, and the scraper 6 can be stored when not in use, thus improving the adaptability of the equipment. Example 2

[0026] Please see Figures 1 to 4, on the basis of the first embodiment, in order to install the fixing frame 5, the fixing frame 5 is in the shape of a "U" - shaped plate structure. On both sides of the surface of the fixing frame 5, fixing plates 7 are fixedly connected. On the surface of the fixing plates 7, a plurality of first bolts 8 are screwed. The first bolts 8 penetrate through the bottom end of the excavator body 1. By setting the first bolts 8, the fixing frame 5 is installed at the bottom end of the excavator body 1, which is convenient for disassembling and installing the entire cleaning mechanism and facilitating maintenance;

[0027] On both sides of the surface of the fixing frame 5, sliding grooves 9 are opened. The sliding grooves 9 are square grooves. The sliding plate 12 can only move linearly along the direction defined by the sliding grooves 9. On the surface of the sliding grooves 9, two groups of limiting grooves 10 are opened. By setting two groups of limiting grooves 10, the mud scraping plate 6 has two different heights. When the limiting block 15 is fixed to the upper limiting groove 10, the surface of the mud scraping plate 6 away from the crawler 3 is stored and no longer cleaned. When the limiting block 15 is fixed to the lower limiting groove 10, the mud scraping plate 6 fits on the surface of the crawler 3 for cleaning. The sliding plate 12 is slidably connected to the surface of the sliding groove 9, and the sliding plate 12 is in the shape of a square plate structure;

[0028] On the surface of the sliding plate 12, rubber holes 17 are opened. At the center position of the rubber holes 17, rubber blocks 14 are fixedly connected. Two limiting blocks 15 are fixedly connected to both sides of the rubber block 14. The limiting blocks 15 are in the shape of square blocks. One end of the two limiting blocks 15 away from each other is embedded in the surface of the limiting groove 10. On the surface of the limiting block 15, extension blocks 16 are fixedly connected. When pressing the extension block 16 to make the limiting block 15脱离限位槽10时, the rubber block 14 can undergo elastic deformation during the force application process. When the limiting block 15 is re - embedded in the limiting groove 10, the elasticity of the rubber block 14 can help the limiting block 15 quickly and accurately snap into the limiting groove 10 to achieve position locking. Embodiment Three

[0029] Please refer to Figures 1 to 5 , on the basis of the second embodiment, in order to enable the mud scraping plate 6 to better fit on the surface of the crawler 3, square holes are opened on the surface of the sliding plate 12. The square holes are communicated with the rubber holes 17. The extension block 16 penetrates through the square holes. The length of the extension block 16 is greater than the groove depth of the square holes. The connecting plate 11 is in the shape of a square plate structure. On the surface of the connecting plate 11, two central holes 18 are opened. The central rod 13 penetrates through the surface of the central holes 18. The central holes 18 are in the shape of circular plates with a "T" - shaped cross - section. A spring 19 is sleeved on the surface of the central holes 18. One end of the spring 19 is fixedly connected to the surface of the connecting plate 11. The spring 19 can automatically adjust the pressure between the mud scraping plate 6 and the crawler 3 according to the surface condition of the crawler 3, always keeping the mud scraping plate 6 in good contact with the surface of the crawler 3 and ensuring that the mud scraping effect is not affected by the change of the crawler surface;

[0030] It should be noted that in the original text, there is a part "当按压延伸块16使限位块15脱离限位槽10时" which seems to be incomplete in the English translation part. It should be something like "When pressing the extension block 16 to make the limiting block 15 disengage from the limiting groove 10". Please check and correct it according to the actual situation.The other end of the spring 19 is fixedly connected to the surface of the scraper 6. The scraper 6 has an arc-shaped plate structure, which allows the scraper 6 to better fit the curved surface of the track 3. The scraper 6 has a beveled surface on the end of the scraper 6 that is close to the track 3.

[0031] In actual use, when it is necessary to clean the surface of the track 3, the operator presses the extension blocks 16 on both sides. Pressing the extension blocks 16 will cause the rubber block 14 to deform elastically, which will cause the limit block 15 to disengage from the limit groove 10 on the surface of the fixed frame 5. At this time, the lock between the sliding plate 12 and the fixed frame 5 is released. The sliding plate 12 is slid to the bottom of the sliding groove 9. The extension blocks 16 are released, and the rubber block 14 returns to its original state from the compressed state. The limit blocks 15 on both sides pop out and are embedded in the limit groove 10 of the lower set. At this time, the scraper 6 is in contact with the surface of the track 3. When the excavator body 1 is running, the track 3 rotates, and the scraper 6 in contact with the surface of the track 3 scrapes off the mud, sand and other debris attached to the surface of the track 3. During the scraping process, the spring 19 is constantly fine-tuned according to the actual situation of the surface of the track 3.

[0032] When the scraper 6 is needed, press the extension blocks 16 on both sides again to lock the limiting block 15 with the uppermost limiting groove 10 of the fixing frame 5. The limiting block 15 drives the connecting plate 11 and the scraper 6 away from the surface of the track 3. When the excavator body 1 no longer moves and only performs rotating excavation work in place, or when the excavator is performing excavation work on dry ground, the scraper 3 will not touch the surface of the track 3, and thus will not affect the normal excavation work of the excavator body 1.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
