Abstract
The utility model discloses a middle scarifier for a grader. The middle scarifier is a soil scarifying device mounted between a steering front axle and a working scraper knife of the grader and consists of teeth, a base, a connection plate, plugs, a pin shaft and a hydraulic system, wherein the teeth are locked in rectangular through holes of the base by the plugs; the base is connected with a front frame of the grader by the connection plate; and one end of a hydraulic cylinder of the hydraulic system is connected with a front frame spherical hinge of the grader, while the other end of the hydraulic cylinder is connected with a base spherically hinge. The height above the ground and the depth into the soil of the scarifier are changed by controlling the telescoping of the hydraulic cylinder.
Description
Technical field
The utility model relates to a kind of mid-ridge buster that is installed between land leveller propons and the perching knife.
Background technology
At present, land leveller be mainly used in large-area ground smooth, scrape operations such as slope and snow removing, still; To the solid operation place of soil layer; Land leveller carries out operation has great difficulty, and blade abrasion is very fast, and smooth effect is also undesirable; Therefore need the operation of loosening the soil of corresponding scarifier attachment before smooth, operating cost increases greatly like this.
Summary of the invention
Can not abolish the deficiency of firm stratum in order to overcome existing land leveller, the utility model provides a kind of land leveller to use mid-ridge buster, and the mid-ridge buster of this kind breaks, becomes flexible hard soil layer, so that perching knife carries out smooth operation through rake teeth.
The purpose of the utility model is achieved in that the mid-ridge buster of this land leveller is made up of rake teeth, pedestal, junction plate, latch, bearing pin and hydraulic system.Wherein, rake teeth is stuck in latch on the rectangular through-hole of pedestal, and pedestal links to each other with the land leveller forebay through junction plate, and hydraulic jack one end of hydraulic system is connected with the front frame ball pivot of land leveller, and the other end is connected with the pedestal ball pivot.Through terrain clearance and embedded depth that the control hydraulic jack stretches and changes ridge buster, during work, rake teeth is cut soil, and package unit advances under land leveller tractive force promotes, and soil layer simultaneously breaks.
Described pedestal is " V " shape box-structure.
Described rake teeth is provided with two teeth groove, can select one of them as required for use, realizes secondary adjustment embedded depth.
The beneficial effect of the utility model is that by the operation of loosening the soil of middle ridge buster, convenient work perching knife carries out smooth work; Avoid perching knife to receive the wearing and tearing of firm stratum; Save the input extras simultaneously, this ridge buster simple in structure, the driving force of the process of loosening the soil is provided by land leveller itself.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the elevation of present embodiment.
Fig. 2 is the vertical view of pedestal.
Fig. 3 is the assembling drawing of rake teeth.
Among the figure: 1. junction plate 2. hydraulic systems 3. vehicle frame ball pivots 4. bearing pins 5. pedestals
6. rake teeth 7. pedestal ball pivots 8. latches
The specific embodiment
Junction plate (1) upper end connects through bearing pin (4) with the land leveller front frame; The lower end is fixed by bolts on the pedestal (5); The lift cylinder upper end of hydraulic system (2) is hinged with the vehicle frame ball pivot (3) on the land leveller front frame, and the pedestal ball pivot (7) on lower end and the pedestal (5) is hinged, and the teeth groove on the rake teeth (6) is stuck on the rectangular through-hole of pedestal (5); Latch (8) inserts the rectangular through-hole of pedestal (5), compresses rake teeth (6).Through above installation, accomplish present embodiment.
Claims (2)
1. a land leveller is used mid-ridge buster; Mainly form by rake teeth, pedestal, junction plate, latch, bearing pin and hydraulic system; It is characterized in that: rake teeth is stuck on the pedestal through hole with latch; Pedestal links to each other with the land leveller forebay through junction plate, and hydraulic jack one end of hydraulic system is connected with the front frame ball pivot of land leveller, and the other end is connected with the pedestal ball pivot.
