Abstract
The utility model discloses a kind of ground film crops drag links earthing knife, including cutterhead, the middle part of the cutterhead, which is run through, is equipped with drive shaft；Circumferential direction along the cutterhead is equipped with several groups blade；The part that blade described in every group is connect with cutterhead is root, and the part opposite with root is top on blade；The top is crimped towards root, and is gradually increased by the rear end part radius of curvature of the front end portion of the root to root.Laminating machine earthing knife in the utility model uses the blade for the arc-shaped shape that curves inwardly, and the rear end part radius of curvature of the front end portion of blade root to blade root is gradually increased.Using the design of above-mentioned special shape, on the one hand soil is effectively dug；On the other hand allow so that the soil dug swings to same one side along the direction of blade tip, greatly improve earthing effect.
Description
Technical field
The utility model relates to a kind of agricultural machinery, in particular to a kind of ground film crops drag links earthing knife.
Background technique
Plastic-film-covered cultivation technology, i.e., after the ridging of farmland, the mechanically or manually laying plastic on ridge, then at mulch both ends
It is compact with soil to carry out burying side.When burying side to mulch both ends progress earthing using laminating machine, the quality of earthing directly affects agriculture
The growth of crop, and the quality of earthing is then directly determined that therefore, the shape and performance of earthing knife are with regard to extremely important by earthing knife.
Although earthing knife in the prior art can also effectively dig soil, the soil dug can be to earthing knife
Soil is thrown in the left and right sides, can not effectively cover on mulch, earthing effect is poor.To guarantee to generally require the abundant earthing of mulch
Extend and carry out earthing, while increasing excessive power drain, also adds the labor intensity of operating personnel.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of ground film crops drag links earthing knives, so that dig
Soil can throw to side completely, improve earthing effect.
In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows:
A kind of ground film crops drag links earthing knife, including cutterhead, the middle part of the cutterhead, which is run through, is equipped with drive shaft；Along institute
The circumferential direction for stating cutterhead is equipped with several groups blade；The part that blade described in every group is connect with cutterhead is root, on blade with root
Opposite part is top；The top is crimped towards root, and by the rear end part of the front end portion of the root to root
Radius of curvature is gradually increased.
Further, the blade and cutterhead are integrally formed.
Further, the blade and cutterhead are split-type design, and the blade is bolted to connection with cutterhead.
Further, the blade is provided with 3-6 group.
Further, the drive shaft is equipped with dowel hole.
The beneficial effects of the utility model are:
Compared with prior art, the laminating machine earthing knife in the utility model uses the knife for the arc-shaped shape that curves inwardly
Piece, and the rear end part radius of curvature of the front end portion of blade root to blade root is gradually increased.Using above-mentioned special shape
Design, on the one hand soil is effectively dug；On the other hand allow so that the soil dug is along blade tip
Direction swing to same one side, greatly improve earthing effect.
Detailed description of the invention
Fig. 1 is the utility model blade and cutterhead unitary design structural schematic diagram；
Fig. 2 is the utility model blade and cutterhead split-type design structural schematic diagram.
In figure, 1- cutterhead, 2- drive shaft, 3- blade, the root 3a-, the top 3b-, 4- dowel hole.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Figs. 1-2, a kind of ground film crops drag links earthing knife, including cutterhead 1, the middle part of the cutterhead 1 are run through
Equipped with drive shaft 2, drive shaft 2 with ground film crops drag links power transmission shaft portion for being attached；Along the week of the cutterhead 1
It is equipped with several groups blade 3 upwards, effect one of blade 3 is to dig soil, the other is falling the soil dug
Earthing is carried out to the end of mulch；The part that blade 3 is connect with cutterhead 1 described in every group is root 3a, on blade 3 with root 3a phase
Pair part be top 3b；The top 3b is crimped towards root 3a, and by the front end portion of the root 3a to root 3a's
Rear end part radius of curvature is gradually increased.Wherein, blade 3 uses the design of the above-mentioned arc-shaped shape that curves inwardly, and blade root
The rear end part radius of curvature of front end portion to blade root be gradually increased.Using the design of this kind of special shape, on the one hand
Soil is effectively dug；On the other hand allow so that the soil dug swung to along the direction of blade tip it is same
Side greatly improves the earthing effect to mulch end.
Specifically, the blade 3 is integrally formed with cutterhead 1.It can be by being cut to cutterhead, then to the part of cutting
Bending is carried out, the blade and cutterhead of unitary design shown in the utility model Fig. 1 can be obtained.
Specifically, as shown in Fig. 2, the blade 3 and cutterhead 1 are split-type design, and the blade 3 passes through with cutterhead 1
Bolt is fixedly connected.Using this kind of split type design, convenient for the installation and replacement of blade 3, and when certain a piece of breaks down, no
It is replaced with whole.
Specifically, the blade 3 is provided with 3-6 group.
Specifically, the drive shaft 2 is equipped with dowel hole 4.Using the design method of dowel hole 4, it is convenient for drive shaft 2
With the installation and replacement of the power transmission shaft of ground film crops drag links.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
