Abstract

The utility model relates to a ridge side weeding cutter, comprising two weeding knives, a left weeding knife and a right weeding knife which are respectively mounted on two sides of a power output device of a micro-cultivator. The two revolving weeding knives can remove weeds on ridge sides when walking along a furrow bottom between two ridges. Both lateral faces of a support rack A and a support rack B are provided with weed cutting edges for cutting off weeds from the ridge sides, thereby preventing the weeding knives from being twisted with weeds. An angle alpha enables cutting blades to copy the shape of the ridge sides, and an angle beta enables the cutting blades to inserting into the earth to remove weeds, thereby increasing weeding efficiency. A knife pivot is connected with a hollow shaft by a pin through different pin holes, thereby adjusting the space between the left and the right weeding knives. The ridge side weeding cutter has the advantages of simple structure, reliable performance and low manufacture cost, and can effectively remove weeds for ridge cultured crops.

Description

Ridge group weeding cutter

Technical field the utility model relates to a kind of farmland operation facility, is specifically related to the matching used ridge of a kind of and miniature cultivator group weeding cutter.

Background technology is along with level of farming mechanization improves constantly, and agricultural machinery is a large amount of heavy manual labors for people have removed, from cargo handling operations such as farming, sowing, intertillage, results.For the crops of some ridge culture, removing ridge group weeds is onerous toils.Though multiple removal ridge group weeds work tool is arranged at present, complex structure, the facility cost is higher.

The summary of the invention the purpose of this utility model is that the weeding cutter is helped on a kind of ridge simple in structure, that can remove ridge group weeds of design.

Two cover weeding cuttves were formed about ridge of the present utility model helped the weeding cutter by mutual symmetry; Every cover weeding cutter is made up of cutter shaft, A support, B support and 2 weeding blades, and described cutter shaft is solid semiaxis; It is characterized in that:

1, A support and B support are fixed on the cutter shaft, and 2 weeding blades are fixed on the end face of A support and B support; Wherein, a slice weeding blade is fixed on an end of A support and B support, and another sheet weeding blade is fixed on the other end of A support and B support;

2, cutter shaft is round steel pipe or square steel tube, is socketed on the hollow shaft, and hollow shaft is connected with the power take-off of miniature cultivator, and hollow shaft has several pin-and-holes, has several corresponding pin-and-holes on the cutter shaft, and cutter shaft is realized being connected by pin with hollow shaft; It is best that described several pin-and-holes are selected 3 pin-and-holes;

3, A support and the equal parallelogram of B support, the folded acute angle in its adjacent both sides is penetrating angle β, β=15 °～23 °; Blade is all worn on the long limit of A support and B support; Described penetrating angle β, selecting β=20 ° be the best;

4, the length of A support is greater than the B support, and the angle that is fixed on two blades on A support and the B support is α, α=30 °～50 °; Selecting α=40 ° be the best;

Two cover weeding cuttves were formed about ridge of the present utility model helped the weeding cutter by mutual symmetry, left side weeding cutter and right weeding cutter are installed in the both sides of miniature cultivator power take-off respectively, when the bottom of trench of walking between Liang Long, the left and right sides weeding cutter of rotation can be removed the weeds that help on the ridge, careless cutting edge is respectively cut in the two sides of A support and B support, can cut off from ridge group and remove the weeds that get off, thereby avoid the weeding cutter to twine grass, the α angle can make the profiling effect of weeding blade ridging group; The β angle can make the weeding blade work the herbicide effect that buries, and has improved weeding ratio.Cutter shaft is connected by different pin-and-holes by pin with hollow shaft, the spacing of two cover weeding cuttves about can regulating.Simple, the dependable performance of ridge group's weeding knife structure of the present utility model, low cost of manufacture can be carried out effective weeding operation to the ridge group of ridge culture crop.

Embodiment is helped the weeding cutter in order fully to disclose ridge of the present utility model, is illustrated below in conjunction with embodiment.

Embodiment: ridge group weeding cutter

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, ridge group weeding cutter is made up of symmetrical left weeding cutter 1 and right weeding cutter 3.Every cover weeding cutter is made up of cutter shaft 11, A support 13, B support 14, weeding blade 12 and weeding blade 16.Weeding blade 12 is identical with the shape of weeding blade 16.A support 13 and B support 14 are fixed on the cutter shaft 11, and weeding blade 12 is fixed on an end of A support 13 and B support 14; Weeding blade 16 is fixed on the other end of A support 13 and B support 14; The length of A support 13 is greater than B support 14, as shown in Figure 5, connect the two ends of A support and B support respectively, the angle α of its line is that the angle of weeding blade 12 and weeding blade 16 is α, design α=40 °, then left weeding cutter 1 and right weeding cutter 3 can carry out shape cutting to the ridge group on ditch both sides; A support 13 and B support 14 equal parallelograms, the folded acute angle in its adjacent both sides is β, β=20 °, described acute angles beta is the penetrating angle of weeding blade 12 and weeding blade 16 cutting soil; A left side weeding cutter 1 and right weeding cutter 3 are by hollow shaft 4 and sell 5 both sides that are installed in miniature cultivator power take-off 2 respectively, when the bottom of trench of walking between Liang Long, the left weeding cutter 1 and the right weeding cutter 3 of rotation can be removed the weeds that help on ridge, ditch both sides, cutting edge 131 is all worn on the long limit of A support 13 and B support 14, remove the weeds that get off to break apart by chopping, thereby avoid the weeding cutter to twine grass from ridge group.3 pin-and-holes 15 are arranged on the cutter shaft 11, and with axis hole cooperations different on the hollow shaft, the spacing that can regulate left weeding cutter and right weeding cutter, thereby weeding is helped on the ridge that adapts to the ridge culture crop of different spacings, reduces the labour intensity of weeding greatly.
