Description
Technical field
The utility model relates to the agricultural equipment field, relates in particular to a kind of scalable central tie rod.
Background technology
Central tie rod is the critical piece of the machineries such as existing weeder, stalk crasher, Stubble cleaner, and farm machinery is hanging method as similar in Fig. 1 mostly: by the tractor rear-mounted, farm machinery is hung up, by the power take-off driving mechanical rotary work of tractor back.Similarly method of work has characteristics: namely equipment and tractor are rigidly connected, equipment working face and tractor two-wheeled ground keeping parallelism.So just a problem occurs: when the tractor descending, the equipment working face that the tractor back hangs will be low, sometimes with regard under deep ground level; When tractor went up a slope, the equipment working face was just high, and sometimes overhead very high, this mode there is no big harm to rotary tillage, plow etc.But if weeding wants namely to remove grass, keep again grass roots (preventing erosion), such working method just dying.The ground rotary tillage, or careless stay very high.Operating mode is very unstable.
The utility model content
The utility model is for the prior art above shortcomings, a kind of scalable central tie rod is provided, the automatically retractable central tie rod is installed on weeder, make the weeder within the specific limits can be with the parallel unsteady operation in ground, the consumption of tractor energy is greatly reduced, and make herbicidal effect can satisfy people's requirement.Good through the evidence result of use.
The purpose of this utility model is to be achieved through the following technical solutions:
a kind of scalable central tie rod, comprise adjusting nut, movable balls oblique crank Z bar, fixing spherical axostylus axostyle, described central tie rod middle part is provided with adjusting nut, one end is provided with movable balls oblique crank Z bar, the other end is provided with fixing spherical axostylus axostyle, described adjusting nut middle part is arranged with central channel along center line, described movable balls oblique crank Z bar is slidably connected in described adjusting nut one end, one end of the adjusting nut that described movable balls oblique crank Z bar is deep is provided with can be at the spring spindle of adjusting nut central channel activity, described adjusting nut outside cover has spring, described spring one end withstands on the termination of adjusting nut, on the spring spindle of other end top, described adjusting nut other end screw is connected and fixed spherical axostylus axostyle.Described adjusting nut is formed from steel.
The utility model beneficial effect: simple in structure, cost is lower, rational in infrastructure, be beneficial to popularization, result of use is good.

Embodiment
The below is described in further detail the utility model according to drawings and embodiments:
as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of scalable central tie rod, comprise adjusting nut 3, movable balls oblique crank Z bar 1, fixing spherical axostylus axostyle 5, described central tie rod middle part is provided with adjusting nut 3, one end is provided with movable balls oblique crank Z bar 1, the other end is provided with fixing spherical axostylus axostyle 5, described adjusting nut 3 middle parts are arranged with central channel 6 along center line, described movable balls oblique crank Z bar 1 is slidably connected in described adjusting nut 3 one ends, one end of the adjusting nut 3 that described movable balls oblique crank Z bar 1 is deep is provided with can be at the spring spindle 4 of adjusting nut central channel 6 activities, described adjusting nut 3 outside covers have spring 2, described spring 2 one ends withstand on the termination of adjusting nut 3, on other end top spring spindle 4, described adjusting nut 3 other end screws are connected and fixed spherical axostylus axostyle 5.
During making, the adjusting nut Central Symmetry in the middle of central tie rod is opened a groove, with an end ball bearing screw thread structure, make slide construction into, one of the spherical axostylus axostyle of an end top installation of slip can be at the spring spindle of adjusting nut central channel activity.And on adjusting nut, a spring is installed, and an end withstands on the termination of nut, and the other end withstands on the spring spindle of lead screw.Realize the automatically retractable central tie rod, when mounted, mounting teeth wheel-speed regulating change box 9, driving pulley, weeding cutter 10, cutter, dancer and install scalable central tie rod 7 on top on frame 8, the weeding cutter 10 of this kind equipment, can be crooked, can be also straight, can be sheet, can be also can according to the plot soil regime, determining as analysis-by-synthesis such as stone content, vegetation structures of rope form.During use, this scalable central tie rod 7 is arranged on weeder, is arranged on side of tractor with fixing spherical axostylus axostyle 5 one ends of screw thread, and movable balls oblique crank Z bar 1 slide bar one side is arranged on weeder one side.The spring spindle 4 of activity is adjusted at the interlude that is positioned at adjusting nut central channel 6.When tractor went up a slope, the weeder dancer headed on scalable central tie rod forward like this; When the tractor descending, weeder hauls scalable central tie rod Compress Spring backward.Push rod is when intermediateness, and the elastic force of spring can also alleviate the pressure of some weeder dancers.The scalable central tie rod equipment of this kind can also be the multiple uses such as stalk crasher, Stubble cleaner, weeder, deicing machine.
