[0033] In order to facilitate the understanding of those skilled in the art, the structure of the present application will be further described in detail in combination with the drawings:

[0034] Referring to Figures 1-5 , a flat ground tool, comprising:

[0035] The mounting frame 1 is used to connect the corresponding vehicle; specifically, the vehicle is a sliding vehicle;

[0036] The scraper 2 is connected to the mounting frame 1 and the front side is recessed to form a scraping part 21, and the height of the lower end of the scraper 2 is driven to rise and fall by the adjusting driving device 6;

[0037] The connecting frame 3 is connected to the scraper 2 and is provided to extend forward;

[0038] The walking wheel 4 is rotatably connected to the front end of the connecting frame 3 by the swing seat 41 and is used to rotate and walk.

[0039] The guiding mechanism 5 comprises a guiding piece 51 connected to the swing seat 41 and arranged between the scraper 2 and the walking wheel 4, the left and right ends of the guiding piece 51 are arranged forward and towards each other, the front wall of the guiding piece 51 forms a displacement slot 511 corresponding to the cover arranged at the rear side of the walking wheel 4, and the rear wall forms a guiding part 512 with a width gradually decreasing from front to back.

[0040] The above structure is provided by adding the guiding mechanism 5, which realizes that when the scraper 2 scrapes the ground forward, the material scraped by the scraper 2 is blocked by the guiding part 512 and guided to the left and right sides of the walking wheel 4, so that the material scraped by the scraper 2 is mainly accumulated on the left and right sides of the walking wheel 4, avoiding excessive accumulation of the material on the rear side of the walking wheel 4, and preparing for the retreat of the walking wheel 4 in advance. On this basis, when the scraper 2 is returned backward, the material on the rear side of the walking wheel 4 is pushed by the guiding part 512 to the left and right sides of the walking wheel 4, so that the guiding part 512 opens the way in advance on the rear side of the walking wheel 4, and the walking wheel 4 can smoothly pass through the material accumulated on its rear side, so as to ensure that the flat ground efficiency is not affected by the accumulated material, and at the same time, it can be ensured that when the scraper 2 scrapes the ground forward again, the walking wheel 4 passing through the accumulated material will not be excessively lifted to cause the change of the height of the scraper 2, and the flat ground effect is ensured.

[0041] Specifically, the number of the walking wheel 4 is two and is distributed on the left and right sides, and the number of the guiding mechanism 5 is two and corresponds to the walking wheel 4 one by one. In order to avoid that the material scraped by the scraper 2 excessively expands to the left and right sides of the scraped ground, the left and right sides of the scraper 2 are respectively provided with front and rear extending baffles 22, the distance between the guiding pieces 51 of the two guiding mechanisms 5 is arranged, the two guiding pieces 51 are arranged on the front side between the two baffles 22 and are respectively arranged at a distance from the corresponding side of the baffle 22, and the distance between the two baffles 22 and the two guiding parts 512 forms a guiding area towards the left and right sides of the two walking wheels 4. Therefore, through the blocking effect of the two baffles 22, the material scraped by the scraper 2 can be prevented from excessively expanding to the left and right sides of the scraped ground, and on this basis, through the arrangement of the two guiding pieces 51 on the front side between the two baffles 22 and at a distance from the corresponding side of the baffle 22, the blocking effect of the two baffles 22 and the guiding effect of the two guiding parts 512 can exist at the same time and do not interfere with each other, and together form a guiding area towards the left and right sides of the two walking wheels 4. While avoiding excessive left and right expansion of the material, the material is not excessively accumulated on the rear side of the walking wheel 4, and the controllability of the material accumulation is improved.

[0042] In order to avoid the damage of the guide 51 to the scraped ground, the lower end of the guide 51 is located between the lower end of the walking wheel 4 and one-third of the height. Therefore, by setting the height of the lower end of the guide 51 from the ground, on the basis of avoiding damaging the scraped ground, the guide part 512 blocks the guiding material, so that the material accumulated behind the walking wheel 4 is not higher than one-third of the height of the walking wheel 4, so as to ensure that the walking wheel 4 can pass through the accumulated material stably when it retreats.

Therefore, by adding the reinforcing members 52 and the first support wheels 53, the support strength of the lower part of the guide 51 can be improved, so as to strengthen the pressure resistance of the guide 51 erected on the rear side of the walking wheel 4, so that when the guide part 512 plays a role of blocking the guiding or pushing the material, the stress can be conducted to the reinforcing members 52 through the first support wheels 53, and then conducted to the swing seats 41, the swing rods 31 and the connecting frame 3 for dispersion, thereby improving the stability of the guide 51 as a whole to reduce the probability of breaking and prolong the service life.

[0044] In order to further improve the pressure resistance of the guide 51, the folding part between the offset part 521 and the rear end of the reinforcing member 52 is rounded to form a folding part 523 corresponding to the left and right inner walls of the accommodation groove 511, and a plurality of second support wheels 54 are rotatably arranged in the folding part 523 from top to bottom. Therefore, by providing the folding part 523 and the plurality of second support wheels 54, the support strength of the left and right sides of the guide 51 can be improved, and the pressure resistance of the guide 51 erected on the rear side of the walking wheel 4 can be further improved, so that when the guide part 512 plays a role of blocking the guiding or pushing the material, the stress can also be conducted to the reinforcing members 52 through the second support wheels 54, and then conducted to the swing seats 41, the swing rods 31 and the connecting frame 3 for dispersion, thereby further improving the stability of the guide 51 as a whole to reduce the probability of breaking and prolong the service life.

[0045] In order to improve the structural strength of the reinforcing member 52, a plurality of reinforcing rods 55 are arranged in up-down intervals between the rear end of the reinforcing member 52 and the offset portion 521, and between the offset portion 521 and the support portion 522. Thus, the structural strength of the reinforcing member 52 is improved by the reinforcing rods 55, and the support strength and stability of the guide member 51 by the first support wheel 53 and the plurality of second support wheels 54 are improved.

[0046] In order to improve the connection strength of the guide member 51 and the swing seat 41, a connecting plate 56 is arranged on the top of the guide member 51, a fixed frame 57 is arranged on the top of the connecting plate 56 and connected to the swing seat 41, and a plurality of reinforcing ribs 58 are arranged between the fixed frame 57, the connecting plate 56 and the swing seat 41. Thus, the connection strength of the fixed frame 57, the connecting plate 56 and the swing seat 41 is improved by the reinforcing ribs 58.

[0047] In order to improve the adaptability of the two walking wheels 4, the middle portion of the swing rod 31 is hingedly connected to the connecting frame 3, and the swing rod 31 is used to swing when the walking wheels 4 are forced to float up and down. Thus, the left and right walking wheels 4 can respectively float up and down with the ground when walking on uneven road surfaces, and the walking adaptability is improved.

[0048] Specifically, the connecting frame 3 is arranged in a U-shaped structure with an opening facing backward, and the rear end of the connecting frame 3 is hingedly connected to the top of the left and right sides of the scraper 2. A horizontal rod 32 extending left and right is arranged on the inner side of the connecting frame 3. One end of the adjusting driving device 6 is hingedly connected to the middle top of the scraper 2, and the other end is hingedly connected to the middle portion of the horizontal rod 32 to form a fulcrum 33. The upper end of the mounting frame 1 is hingedly connected to the vehicle to form a swing point 11. When the adjusting driving device 6 is lifted with the fulcrum 33 as the support, the scraper 2 and the mounting frame 1 swing upward and forward around the swing point 11.

[0049] The above only describes the preferred embodiments of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
