Detailed description of the invention
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the utility model can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.With reference to Fig. 1, " interior " in full text, mentioned refers to paper direction inwards, and " back of the body " and " outward " refers to the direction that paper is outside.
As Figure 1-3, the utility model specific embodiment provides a kind of perching knife equipment, is arranged on land leveller, for formation of land and plastic operation.This perching knife apparatus for work comprises blade 9, installing plate 3, perching knife support 6, the oil cylinder 7 of extending, the first oil cylinder seat 10 and two guide rails 4 that parallel interval arranges, blade 9 is arranged on the lower limb of installing plate 3, guide rail 4 is fixed on the back side of installing plate 3 along the length direction of blade 9, between two guide rails 4, form mounting groove (not shown), the first oil cylinder seat 10 is fixedly installed on perching knife and supports on 6, perching knife supports 6 and comprises left support plate 61, right support plate 62 and connecting cylinder 63, left support plate 61 and right support plate 62 are separately positioned on the two ends of connecting cylinder 63, the upper and lower of the inner surface of left support plate 61 is respectively equipped with shackle member 65, in shackle member 65, have guide groove, the upper and lower of the inner surface of right support plate 62 is also provided with above-mentioned shackle member 65, guide rail 4 is arranged in guide groove movably, and shackle member 65 can be blocked guide rail 4, make guide rail 4 spacing in draw-in groove, thereby after supporting 6 clampings with perching knife, installing plate 3 just can not separate, preferably, the first oil cylinder seat 10 is arranged on perching knife supports the position at 6 two ends, the cylinder body of oil cylinder 7 of extending is fixed on the first oil cylinder seat 10, the piston rod of oil cylinder 7 of extending points to perching knife and supports the end direction relative with the first oil cylinder on 6, the oil cylinder 7 of extending is sandwiched in installing plate 3 and perching knife supports between 6, and in the mounting groove of piston rod between guide rail 4, the free end of piston rod is connected with installing plate 3, for the ease of the free-ended connection of piston rod, can between two guide rails 4, removably be connected with Connection Block 8, the free end of piston rod is connected on Connection Block 8.
Perching knife equipment in such scheme, because perching knife supports 6 installation, and the oil cylinder 7 of extending supports between 6 at installing plate 3 and perching knife, therefore under the protection of perching knife support 6, can not pound the cylinder body that drops on the oil cylinder 7 of extending from the upturned stone in perching knife top, thus the oil cylinder 7 that reduced to extend injured by a crashing object may; In addition, because piston rod is between the mounting groove between two closed slides 4, therefore, piston rod also can play a very good protection, and like this, the whole oil cylinder 7 of extending can, under effectively protecting, therefore extend the application life of the oil cylinder 7 of extending.
It should be noted that, the first oil cylinder seat 10 is preferably arranged on perching knife and supports two ends of 6, also can be arranged on two optional positions between end, as long as can reduce as far as possible the chance that the oil cylinder 7 of extending is pounded; More preferred, the whole cylinder body of the oil cylinder 7 of extending all supports between 6 at installing plate 3 and perching knife, so just can form the most effectively protection.In addition, for the ease of most of operators' custom, be preferably the right-hand member that the first oil cylinder seat 10 is arranged on to perching knife support 6, whole perching knife can be extended left.
The utility model specific embodiment also provides a kind of land leveller, comprise hitch frame 1, turning circle 2, revolution support, shovel angular transformation oil cylinder 5, the second oil cylinder seat 11 and above-mentioned perching knife equipment, turning circle 2 is supported and is arranged on rotationally on hitch frame 1 by revolution, and the bottom of turning circle 2 and perching knife support 6 lower hinge; Particularly, the upper and lower of left support plate 61 and right support plate 62 inner surfaces has connecting hole 66, the bottom of turning circle 2 also has connecting hole 66, left support plate 61 and right support plate 62 pass above-mentioned connecting hole 66 with the bottom of turning circle 2 by bearing pin and carry out hinged, the second oil cylinder seat 11 is located at perching knife and supports 6 top, and shovel angular transformation oil cylinder 5 one end and the second oil cylinder seat 11 are hinged, and the other end is connected with turning circle 2, by stretching of shovel angular transformation oil cylinder 5, just can regulate the shovel angle of perching knife.
Under practical application, land leveller is generally all with tool box, conventional way is that tool box is arranged in hitch frame 1 or frame, this mounting means not only takes up room, and be easy to interfere in rollover process, in order to address this problem, tool box can be located at perching knife and support on 6, as shown in Figure 3, particularly: left support plate 61, the inside configuration that the barrel of right support plate 62 and connecting cylinder 63 surrounds forms a closed cavity, on the lateral surface of connecting cylinder 63, have window, window is provided with baffle plate 64 that can folding, like this, this cavity just can be used for storing tools, as tool box, particularly, the top edge chain connection of baffle plate 64 and window, the below of baffle plate 64 is locked or is opened by the lower limb of lock piece and window.
Because the effect of perching knife support 6 is also support and connection installing plate 3 and blade 9, connecting cylinder 63 insufficient strength of cavity structure, the work that may cause perching knife equipment is unreliable, therefore can dividing plate 67 be set at cavity inside, and closed cavity is separated into upper cavity volume and lower cavity volume, and window is opened on the outer wall of lower cavity volume, and the inwall of upper cavity volume is provided with reinforcing rib, so both ensured that perching knife supported 6 intensity, also retained the space of storing tools.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
