Problems solved by technology

However, the existing road grader has the following disadvantages: 1, the existing road grader uses the scraper assembly to scrape the farmland, and the scraping effect is not good, especially the soil mounds are easy to form on both sides of the scraper; 2, the existing The frame of the road grader is fixed and cannot be adjusted; therefore, when it is hung on the rear side of the road grader for transportation, the scraper on the road grader is very easy to touch the ground, so this type of road grader is not easy to be moved, and urgently needs improvement

Embodiment Construction

[0017] The preferred embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] Such as Figure 1~Figure 2 A lengthened road grader shown includes a drag frame assembly 1 , a main frame assembly 2 and a trailer assembly 3 connected in sequence. The frame assembly 1 includes a frame frame 11 and a plurality of frame reinforcing rods 12 arranged in the frame frame 11 . The frame 11 of the frame is triangular, and the front end of the frame 11 is hinged with a suspension pipe 13, which is used to connect and fix on the tractor.

[0019] The main frame assembly 2 includes a first main frame 21 and a second main frame 22, the first main frame 21 and the second main frame 22 are rectangular frames, and the front end of the first main frame 21 is connected to the frame frame 11. The rear end is connected and fixed, and the rear end of the first main frame 21 and the front end of the second main frame 22 are...

Abstract

The invention relates to the field of agricultural machinery, and in particular relates to a road leveling machine. The road leveling machine comprises a pulling bracket assembly, a main frame assembly and a towing bracket assembly which are sequentially connected. The road leveling machine carries out inclined scraping and leveling on the ground for multiple times, the scraping and leveling effect is good, mounds formed by the two ends of a scraping knife at the front side can be leveled by a scraping knife at the rear side, a fifth scraping knife is a notched scraping knife, and sandy soil can penetrate through a notched opening of the fifth scraping knife, so that the moulds can not be formed at the two sides of the fifth scraping knife at the most downstream, and the scraping and leveling effect is better; besides, when the road leveling machine is suspended at the rear side of another road leveling machine to be carried, the height of a frame of the road leveling machine can be lifted by virtue of oil cylinder output, and an oil cylinder component pulls a cord pulling component at the same time, so that a towing bracket main body rotates and turns up relative to a second main frame and even can be folded to be above the second main frame, and a scrapping plate is avoided from being in contact with the ground when the road leveling machine moves.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a road grader. Background technique [0002] The road grader is a kind of agricultural machinery used to level the surface of the cultivated field. This type of agricultural grader is different from the grader in civil engineering. This type of agricultural grader is connected to the rear side of the tractor, and the front is provided by the tractor. In the process of moving forward, the scraper is used to scrape the surface of the farmland. However, the existing road grader has the following disadvantages: 1, the existing road grader uses the scraper assembly to scrape the farmland, and the scraping effect is not good, especially the soil mounds are easy to form on both sides of the scraper; 2, the existing The frame of the road grader is fixed and cannot be adjusted; therefore, when it is hung on the rear side of the road grader for transportation, the scraper on the road...
