Abstract
Pressure spring and unsteady feeler mechanism of extension spring combination formula weeder assembly belongs to agricultural machine, telescopic screw rod axially movable's cartridge is in the through -hole of frame assembly, and telescopic screw rod connects through hinge round pin axle and weeding roller assembly hinge, and the compression spring suit is on telescopic screw rod, and pressure spring pressure adjusting nut joins in marriage the dress on telescopic screw rod screw thread position the dress is joined in marriage on the extension spring screw rod to axially movable's installation extension spring screw rod on the frame assembly, extension spring tension adjustment nut, and tension springs's both ends are connected respectively on extension spring screw rod and weeding roller assembly, this mechanism adopts compression spring and tension springs cooperation to regulate and control weeding roller assembly profile modeling action jointly, have that novel structure, profile modeling reaction are quick, the action in time quick, the synchronism is good, the profile modeling precision high, work quality is good, the operation trouble is few, extensive applicability's characteristics.
Description
Technical field
The invention belongs to agricultural machinery, relates generally to the weeder assembly floating copying Working mechanism on weed control equipment.
Background technology
Mechanical type extirpator is China's the most universal currently used intertillage operation facility, and the agricultural district that especially many people are few on ground uses the most extensive, serves certain effect for mechanization of agriculture intertillage operation and increasing crop yield.In recent years, needing along with pollution-free food production and reduce chemical fertilizer, proposition that pesticide, " three subtract " of herbicide require, weeding by machine is mentioned in operation schedule again again.At present, although mechanical type extirpator model is more, but its mechanical weeding device assembly installation in its frame all uses rigid structure to fix, during operation, each weeder assembly can not carry out forming movement with landing ground height, reduce quality and the effect of middle weeding operation, intertilling deep mixed, weeding ratio declines, and even causes bigger Seedling of hindering to lose.For solving the problems referred to above, the applicant once have studied the weeder mechanism of a kind of floating copying, owing to being the relocation mechanism using single stage clip to control, there is also operation quality and problem that effect has much room for improvement needs to solve during operation.
Summary of the invention
The purpose of the invention is aiming at problem and the defect that above-mentioned prior art exists, design provides a kind of stage clip and extension spring combination type weeder assembly float profiling mechanism, reaches to increase substantially weeding operation quality and the purpose of efficiency in mechanical weeding device assembly.
nullThe Basic Design of the invention is: stage clip and extension spring combination type weeder assembly float profiling mechanism include support assembly，Equipped land wheel on described support assembly following side，Rotating installation swing span on the land axle of land wheel，Rotating installation weeding roller assembly on described swing span rear portion，Chain is sleeved on land axle and weeding roller assembly and connects，The front side portion of expansion screw is axially reciprocal in the through hole being inserted into support assembly top of movement，Described expansion screw rearward end is hinged with weeding roller assembly top by hinge bearing pin，Compression spring is sleeved on expansion screw，Before described compression spring、Rear end contacts cooperation with the step surface on support assembly and expansion screw respectively，Equipped stage clip pipe regulating screw nut on screw thread position on front side of described expansion screw，Described stage clip pipe regulating screw nut contacts with support assembly；The installation extension spring screw rod being axially movable on described support assembly, tension spring tension adjusting nut is fitted on extension spring screw rod front portion, and contacts cooperation with support assembly, and the two ends of tension spring are connected on extension spring screw rod rear portion and weeding roller assembly top.
The invention uses stage clip to coordinate common regulation and control weeding roller assembly with extension spring, achieve mechanical weeding roller assembly profiling operation function with surface relief when intertillage operation, have that novel structure, profiling be quick, action in time, quickly, synchronicity is good, copying accuracy is high, operation quality is good, operation fault is few, the suitability wide, the feature that can be fitted in easily on each class mechanical type cultivating equipment.

Detailed description of the invention
Below in conjunction with the accompanying drawings the invention embodiment is described in detail.nullA kind of stage clip includes support assembly 1 with extension spring combination type weeder assembly float profiling mechanism，Equipped land wheel 2 on described support assembly 1 following side，Rotating installation swing span 4 on the land axle 3 of land wheel 2，Rotating installation weeding roller assembly 5 on described swing span 4 rear portion，Chain 6 is sleeved on land axle 3 and weeding roller assembly 5 and connects，The front side portion of expansion screw 8 is axially reciprocal in the through hole being inserted into support assembly 1 top of movement，Described expansion screw 8 rearward end is hinged with weeding roller assembly 5 top by hinge bearing pin 7，Compression spring 9 is sleeved on expansion screw 8，Before described compression spring 9、Rear end contacts cooperation with the step surface on support assembly 1 and expansion screw 8 respectively，Equipped stage clip pipe regulating screw nut 13 on screw thread position on front side of described expansion screw 8，Described stage clip pipe regulating screw nut 13 contacts with support assembly 1；The installation extension spring screw rod 10 being axially movable on described support assembly 1, tension spring tension adjusting nut 11 is fitted on extension spring screw rod 10 front portion, and cooperation is contacted with support assembly 1, the two ends of tension spring 12 are connected on extension spring screw rod 10 rear portion and weeding roller assembly 5 top.
During operation, according to the depth requirements of middle weeding operation, tension spring tension adjusting nut 11 and stage clip pipe regulating screw nut 13 is utilized to regulate weeding roller assembly 5 height and position, it is achieved pulling force and the static balance of pressure.When weeding roller assembly 5 fluctuates with ground, tension spring 12 can assist the ground of projection to be pulled up by weeding roller assembly 5 the most in time, it is achieved real-time up profiling；Compression spring 9 can assist recessed ground to be pressed for 5 times by weeding roller assembly the most in time, close proximity to ground, it is achieved descending profiling.In scientific experiment, complete machine profiling action is quick, and copying accuracy is high, and real-time, operation quality is good.
