Abstract
A kind of grid type paddy field in the ranks weeder, including axle sleeve and central shaft, the axle sleeve is fixed on weeding disk, grizzly bar uniform welding is between both sides day weeding disk, weeding disk is linked together with support by central shaft, support is fixed together by bearing pin and frame, by installing preloading spring between support and frame, forms profiling flexible connection；It is an advantage of the invention that：Simple in construction, reliability is high, easy to operation, places damage of the field thing really up to the mark to grizzly bar, can reach good herbicidal effect.
Description
Technical field
The present invention relates to agricultural equipment technical field, more particularly, to a kind of grid type paddy field in the ranks weeder.
Background technology
Staple food crop of the rice as China, occupies very important status in national grain-production.Weeds are
The important component of Agro-ecological System, directly with crops contention nutrient, moisture, illumination and space, in turn result in crop
Yield declines, quality reduces.Therefore, the control of weeds is to ensureing that the yield and quality of rice has great meaning.
At present, domestic paddy field weeding mode is mainly chemical weed control.Chemical weed control has efficient, time saving, laborsaving, economical
Feature, its development for widely using to modern agriculture serve facilitation;But problem of environmental pollution is got over caused by residue
Come more serious, disagreed with agricultural sustainable development objective.Weeding by machine is because it has the characteristics that efficiency high, pollution are small, in recent years
Progressively to turn into the Main Trends of The Development of weeding operation.At present, it is domestic still without the paddy cultivator tool of maturation, it is traditional
For drive-type paddy field inter-row weeder because breadth is larger, cornering difficulties, pressure seedling phenomenon is serious.
The content of the invention
To overcome above mentioned problem, the present invention adopts the following technical scheme that：
A kind of grid type paddy field weeder, including axle sleeve and central shaft in the ranks, the axle sleeve are fixed on weeding disk, grizzly bar
Uniform welding is between both sides day weeding disk, and weeding disk is linked together with support by central shaft, and support passes through bearing pin
It is fixed together with frame, by installing preloading spring between support and frame, forms profiling flexible connection.
The grizzly bar uses cold-rolled steel sheet of the thickness for 2mm.
It is an advantage of the invention that：Simple in construction, reliability is high, easy to operation, places damage of the field thing really up to the mark to grizzly bar,
Good herbicidal effect can be reached.
Brief description of the drawings
Fig. 1 is internal structure schematic diagram of the present invention.
Fig. 2 is side view of the present invention.
Embodiment
As shown in Figure 1, 2, a kind of grid type paddy field weeder, including axle sleeve 1 and central shaft 2 in the ranks, the axle sleeve 1 are solid
It is scheduled on weeding disk 8, for the uniform welding of grizzly bar 3 between both sides day weeding disk 8, weeding disk 8 passes through central shaft with support 6
2 are linked together, and support 6 is fixed together by bearing pin 4 and frame 5, by installing preloading spring between support 6 and frame 5
7, form profiling flexible connection.
The grizzly bar 3 uses cold-rolled steel sheet of the thickness for 2mm.
Operation principle is as follows：
During equipment operation, weeding cage advances with frame central shaft uniform roll.Grizzly bar 3 is burying to during being unearthed, 3 kinds of sides
Formula can reach weeding purpose：First, grizzly bar 3 is rotated during burying, weeds are pressed into soil;Second, grizzly bar 3 leaves soil
When, because grizzly bar 3 has one fixed width, the soil of some growth weeds is turned over from the ground;Third, with the rotation of grizzly bar 3, quilt
Turn over soil from the ground and depart from grizzly bar 3 in the presence of gravity and centrifugal force, weeds are buried and covered, prevent it from carrying out photosynthetic work
With withered and dead.
