Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of land leveller modified rocker, comprise upper rocker 1 and the swing rack 2 of integrally casting, described upper rocker 1 comprises middle part semi-cylindrical canyon I 13, and described semi-cylindrical canyon I 13 left and right sides is connected with a left support arm 11 and a right support arm 12; Described left support arm 11 end has fork hole I 14, and left support arm 11 front end has hydraulic draw pin-and-hole I 15, and left support arm 11 lower end is installed with lug 18; Described right support arm 12 end has fork hole II 17, and right support arm 12 front end has hydraulic draw pin-and-hole II 16, and right support arm 12 lower end is installed with lug 18; Described swing rack 2 comprises middle part semi-cylindrical canyon II 22, described semi-cylindrical canyon II 22 both sides and upper rocker corresponding position are respectively connected with a lug 18, described semi-cylindrical canyon II 22 bottom is also connected with a lower branch arm 21, and described lower branch arm 21 end has hinge post hole 23; Described upper rocker 1 and swing rack 2 are removably connected by lug 18.
Further, as shown in Figure 2, described left support arm 11, right support arm 12 and lower branch arm 21, comprise upper flange 111, and upper flange is fixed with web 112 111 times, is fixed with lower wing plate 113 below web 112, and cross section is I shape.
Further, as shown in Figure 3, described lower branch arm 21 adopts orthodrome structure, can effectively reduce stress and concentrate.
Further, the center of described lower branch arm 21 endosternum 112 has through hole 24 according to orthodrome tendency, reduces deadweight while guaranteed strength.
Preferably, described lug 18 has bolt hole, is bolted to connection rocker and swing rack.
Preferably, described upper flange 111 width is less than lower wing plate 113, facilitates the installation of bolt.
Preferably, be the cascaded surface cooperatively interacted at the connection binding face of upper rocker 1 and swing rack 2, increase and firmness is installed.
In use, upper rocker 1 is installed on the top of land leveller rotary disk, and hydraulic pressure is pulled pin I and hydraulic pressure pull pin and II be each passed through hydraulic draw pin-and-hole I 15 and hydraulic draw pin-and-hole II 16, then through hole corresponding on rotary disk.Swing rack 2 is installed on the below of rotary disk, and its two pairs of lugs 18 are connected by bolt with two pairs of lugs 18 of upper rocker 1.Fork I is installed on fork hole I 14, be installed on fork hole II 17, hinge post is installed on hinge post hole 23, the installation being installed as each action tank of fork I, fork II and hinge post provides mount pad, perching knife lift cylinder I is installed on fork I, perching knife lift cylinder II is installed on fork II, is installed on hinge post by perching knife oscillating oil cylinder, such the utility model just completes the installation of each structure.
The principle of action: fork I, fork II are rotary in fork hole I 14 and fork hole II 17, such perching knife lift cylinder I and perching knife lift cylinder II also can realize rotating around fork hole I 14 and fork hole II 17, and their other end is all articulated with hitch frame, although the hinge post hole 23 of hinge post and swing rack is welded together, but perching knife oscillating oil cylinder and hinge post are linked together by the side of ball pivot, it can realize the rotation of any direction, and the other end of perching knife oscillating oil cylinder is also articulated with hitch frame, i.e. perching knife lift cylinder I, perching knife lift cylinder II, perching knife oscillating oil cylinder three oil cylinders are all in succession rocker in one end, in succession hitch frame in one end, therefore when perching knife oscillating oil cylinder stretches, hitch frame realizes corresponding rotation and rotates accordingly with perching knife lift cylinder I and perching knife lift cylinder II, because hitch frame is connected with perching knife by revolving support, so also just achieve the swing of perching knife.When perching knife lift cylinder I and perching knife lift cylinder II stretch, drive the lifting of hitch frame or press down, because hitch frame is connected with perching knife by revolving support, therefore hitch frame lifting or press down the lifting that also just achieves perching knife or press down.Additionally by adjustment hydraulic pressure pull pin I and hydraulic pressure to pull pin II position different on rotary disk, the rotation of rocker on rotary disk can be realized, thus make perching knife can obtain the job area of greater angle.
In sum, the utility model structure is simple, practical and convenient, by the mounting structure of upper rocker and swing rack, reduces the difficulty of withdrawing pattern; Simultaneously by I-shaped structure support arm, improve the load bearing stength of rocker; The orthodrome structure of lower branch arm, can effectively reduce stress and concentrate, and the perforate of lower branch arm endosternum, alleviate the weight of rocker.
