Description

The centrifugal disc weeder

Technical field

The utility model belongs to agricultural machinery, relates generally to cultivating implement.

Background technology

In plant growing process, be very important cargo handling operation to the intertill and clean tillage of intertillage crop soybean, at present, a large amount of chemical agent weedings of using have alleviated the labour intensity of artificial and weeding by machine, have but increased the influence to crops quality.Along with the enhancing of people's environmental consciousness with to the demand of pollution-free food, mechanical system is removed between seedling, weeds in field is subjected to the peasant day by day and welcomes, especially the northern area of China machinery cultivating implement that many people are few on ground obtains than extensive use, but, the prior mechanical cultivating implement is because its fault of construction, the ubiquity weeding rate is lower, the seedling-damaging ratio problem of higher, has reduced the strain number of keeping a full stand of seedings, and has reduced crop yield.

Summary of the invention

The purpose of this utility model is exactly problem and the defective that exists at above-mentioned prior art, design provides a kind of centrifugal disc weeder of new structure, reaches the purpose that increases substantially weeding rate, reduction seedling-damaging ratio, the strain number of keeping a full stand of seedings, helps the yield per unit area raising.

Basic design of the present utility model is that mounting teeth roller box, suspension arm and breast wheel on mainframe, driving wheel fit on the power take-off lower end of gear-box admittedly; Hinge frame front end hinge is contained on the mainframe, the installation subframe is connected on the hinge frame rearward end, equipped expansion link, vertical shaft and Shun Liang on subframe, expansion link top is inserted in the suspension arm, the compression spring housing is contained on the expansion link, and its two ends contact cooperation with suspension arm respectively with subframe, equipped respectively driving wheel and horizontal weeding disc assembly on the upper and lower end of vertical shaft, the grave mound disk is configured in along on the beam rearward end, is positioned at position, both sides, horizontal weeding disc assembly rear relatively; Driving-belt overlaps respectively and fits on driving wheel and breast wheel and breast wheel and the driving wheel; Limit dark supporting plate to be installed on the subframe bottom, and be configured in horizontal weeding disc assembly both sides respectively, so far constitute the centrifugal disc weeder.

The utility model structural design is new reasonable, and operation quality is good, the efficient height, and fault is few, and is easy to use, and has the soil moisture conservation effect of loosening the soil well, helps the raising of crop yield and quality.

Embodiment

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.The centrifugal disc weeder comprises mainframe 16, hanger bracket 1 and land wheel 18, and mounting teeth roller box 2, suspension arm 4 and breast wheel 5 on mainframe 16, driving wheel 17 fit on power take-off 1 lower end of gear-box 2 admittedly; Hinge frame 14 front ends hinge is contained on the mainframe 16, be connected on hinge frame 14 rearward end subframe 11 is installed, equipped expansion link 3, vertical shaft 7 and suitable beam 9 on subframe 11, expansion link 3 tops are inserted in the suspension arm 4, compression spring 6 is sleeved on the expansion link 3, its two ends contact cooperation with suspension arm 4 with subframe 11 respectively, equipped respectively driving wheel 8 and horizontal weeding disc assembly 13 on vertical shaft 7 upper and lower ends, grave mound disk 10 is configured in along on beam 9 rearward end, is positioned at position, both sides, horizontal weeding disc assembly 13 rear relatively; Driving-belt 15 overlaps respectively and fits on driving wheel 17 and breast wheel 5 and breast wheel 5 and the driving wheel 8; Limit dark supporting plate 12 to be installed on subframe 11 bottoms, and be configured in horizontal weeding disc assembly 13 both sides respectively.Land wheel 18 is fitted in outside, mainframe 16 two ends, and every side adopts two land wheel 18 front and back position settings.

During operation, when dynamic power machine draws this machine and forwards moves, the rotary power of its power take-off drives 13 rotations of centrifugal disc weeding assembly through gear-box 2, driving wheel 17, driving-belt 15, breast wheel 5, driving wheel 8, vertical shaft 7, land wheel 18 contacts with furrow ground, the weeding tooth of horizontal weeding disc assembly 13 suitably inserts in the soil, be flat spin line formula combined running, finish the weeding operation, it is killed subsequently ground surface soil being covered on the residual weeds along grave mound disk 10 that can upper and lower adjusting on the beam 9; Limit dark supporting plate 12 to contact embedded depth and the operation quality that has guaranteed the weeding tooth with ground; When the dark supporting plate 12 of limit runs into the ground out-of-flatness, make subframe 11 and hinge frame 14 in the lump around mainframe 16 upper and lower swings, realize the individual profiling of horizontal weeding disc assembly 13, its vertical shaft 7 is upper and lower moving in suspension arm 4 holes, the pressure of compression spring 6 remains the downforce to subframe 11, makes it be in job position all the time.
