Abstract
The utility model provides a grid formula paddy field is weeding device in ranks, includes axle sleeve and center pin, the axle sleeve is fixed on the weeding disc, and the grid evenly welds between both sides day weeding disc, and the weeding disc is in the same place through well spindle connection with the support, and the support is fixed together through round pin axle and frame, through installation pretension spring, forms the profile modeling flexonics between support and the frame, the utility model has the advantages that: simple structure, the reliability is high, and the operation of being convenient for is placed field thing really up to the mark and to the damage of grid, can be reached fine weed control efficacy.
Description
Technical field
The utility model relates to agricultural equipment technical field, especially relates to a kind of grid type paddy field weeder in the ranks.
Background technology
Paddy rice, as the staple food crop of China, occupies very important status in national grain-production.Weeds are important component parts of agricultural ecosystem, and direct and crops fight for nutrient, moisture, illumination and space, and then cause crop yield decline, quality reduction.Therefore, the control of weeds is to ensureing that the yield and quality of paddy rice has great meaning.
At present, domestic paddy field weeding mode is mainly chemical weed control.Chemical weed control has efficiently, save time, laborsaving, economic feature, and it widely uses and serves facilitation to the development of modern agriculture; But the problem of environmental pollution that residue causes is more and more serious, disagrees with agricultural sustainable development aim.Weeding by machine because of its have efficiency high, pollute the features such as little, progressively become the Main Trends of The Development of weeding operation in recent years.At present, domestic still do not have ripe paddy cultivator tool, and traditional driving type paddy field inter-row weeder is because fabric width is comparatively large, cornering difficulties, and pressure seedling phenomenon is serious.
Utility model content
For overcoming the problems referred to above, the utility model adopts following technical scheme:
A kind of grid type paddy field weeder in the ranks, comprise axle sleeve and central shaft, described axle sleeve is fixed on weeding disk, grizzly bar uniform welding is between both sides day weeding disk, weeding disk and support are linked together by central shaft, support is fixed together by bearing pin and frame, by installing preloading spring between support and frame, forming profiling and flexibly connecting.
Described grizzly bar adopts thickness to be the cold-rolled steel sheet of 2mm.
The utility model has the advantages that: structure is simple, and reliability is high, convenient operation, place field and cross the damage of hard object to grizzly bar, good herbicidal effect can be reached.
Accompanying drawing explanation
Fig. 1 is the utility model interior schematic diagram.
Fig. 2 is the utility model end view.
Embodiment
As shown in Figure 1, 2, a kind of grid type paddy field weeder in the ranks, comprise axle sleeve 1 and central shaft 2, described axle sleeve 1 is fixed on weeding disk 8, grizzly bar 3 uniform welding is between both sides day weeding disk 8, and weeding disk 8 and support 6 are linked together by central shaft 2, and support 6 is fixed together by bearing pin 4 and frame 5, by installing preloading spring 7 between support 6 and frame 5, forming profiling and flexibly connecting.
Described grizzly bar 3 adopts thickness to be the cold-rolled steel sheet of 2mm.
Operation principle is as follows:
During facility operation, weeding cage advances with frame central shaft uniform roll.Grizzly bar 3 is burying in unearthed process, and 3 kinds of modes can reach weeding object: one is that grizzly bar 3 rotation is buried in process, is pressed into by weeds in earth; Two is grizzly bars 3 when leaving earth, because grizzly bar 3 has one fixed width, turns over overhead by the earth of some growth weeds; Three is the rotations along with grizzly bar 3, is departed from grizzly bar 3, buried by weeds and cover, make it not carry out photosynthesis by the earth that turns over overhead under the effect of gravity and centrifugal force, withered and dead.
