Problems solved by technology

[0005] 1. The oil cylinder adjustment mechanism of the ripper is located on the top or bottom side of the front frame; if it is located on the top side, it will affect the operator's vision, and if it is located on the bottom side of the front frame, it will limit the movement space of the blade, thus greatly reducing The working range of the shovel working device is defined;
[0006] 2. In order to avoid the limitation of front wheel steering space, the existing center-mounted rippers are mostly designed as a five-bar linkage mechanism, in which the tie rods are of fixed length, which cannot effectively meet people's needs in some working conditions where the depth of ripper needs to be deep; At the same time, due to the characteristics of the five-link structure, when the loosening rake teeth are descending and cutting, the entry angle of the loosening soil is constantly changing. For some land with different working conditions, it is easy to cause the loosening rake teeth to wear faster, and the resistance to loosening is large. Increased overall fuel consumption

Embodiment 1

[0026] Embodiment one: if figure 1 As shown, the scarifier 1 comprises a rocker support 10, the top of the rocker support 10 is hinged with a rocker 9, and the bottom of the rocker support 10 is fixedly connected with the loosening support 12, and the bottom of the loosening support 12 is provided with a loosening arm. Rake teeth 13, support arms 8 are respectively provided on both sides of the soil loosening support 12;

[0027] The two ends of described rocking arm 9 are fixedly connected with oil cylinder 7 and an end of pull rod 11 respectively, and the other end of oil cylinder 7 is fixedly connected with oil cylinder holder 6, and the other end of pull rod 11 is fixedly connected with loose soil support 12, and oil cylinder 7 can pass through The rocker arm 9 drives the pull rod 11 and the soil loosening bracket 12 to move, so as to realize the adjustment of the height of the soil loosening rake teeth 13;

[0028] Described soil loosening support 12 is provided with low...

Embodiment 2

[0030] Embodiment two: if figure 2 As shown, the pull rod 11 includes an upper pull rod 111, the upper pull rod 111 is provided with a lower rod 114, the upper pull rod 111 and the lower rod 114 are provided with more than one positioning hole, and the positioning hole is provided with a positioning bolt; One is the same.

Embodiment 3

[0031] Embodiment three: as image 3 As shown, the pull rod 11 is a whole with a fixed length; the others are the same as the first embodiment.

[0032] Such as figure 1 As shown, the grader includes the aforementioned ripper 1 , and the ripper 1 is arranged between the front axle 4 of the grader and the blade working device 3 .

Abstract

The invention discloses a grader and a scarifier thereof, belonging to the field of construction machinery. The ripper mainly includes a rocker support. A rocker arm is hinged above the rocker support. The bottom of the rocker support is fixedly connected with the loosening support. The bottom of the loosening support is provided with loosening rake teeth. Support arms are respectively provided; the two ends of the rocker arm are respectively fixedly connected with the oil cylinder and one end of the pull rod, the other end of the oil cylinder is fixedly connected with the oil cylinder fixing seat, and the other end of the pull rod is fixedly connected with the loose soil support; the ripper is placed on the flat ground between the front axle of the machine and the blade attachment. The invention has good cutting visibility, does not affect the steering performance of the front wheels, has good soil loosening and leveling effects, and has high working efficiency. The invention is mainly used for leveling roads and farmland.

Description

technical field [0001] The invention belongs to the field of engineering machinery, and in particular relates to a grader and a scarifier thereof. Background technique [0002] The grader realizes various tasks such as leveling roads and farmland, scraping side slopes, and scraping inclined ditches through the blade working device. In the process of road construction, if the soil base cannot meet the construction standard requirements after being compacted by a road roller, the compacted soil base must be destroyed first, then leveled by a grader, and finally compacted by a road roller; In other working conditions, if the farmland soil is hard, the farmland needs to be loosened in advance and then leveled by a grader. [0003] Existing grader blades cannot achieve the function of loosening the soil efficiently, and need to increase the scarifier to realize it. However, the scarifiers of the existing grader are mostly placed behind the grader, and the field of view is not go...
