Abstract
The present invention relates to a kind of Novel disc hay mover cutter device, including cutterhead, mowing blade, bolt and split pin.Along its circumference at interval of 120 ° of connections, one mowing blade on cutterhead, the length that each mowing blade outer rim stretches out cutterhead circumferential surface is 55mm；Mowing blade passes through the movable connection of blade afterbody perforate with cutterhead using bolt；Mowing blade, which runs into barrier, reversely to be flicked, it is to avoid collision fracture；Mowing blade is rectangle, and two flanks of mowing blade are blade, and two flanks are axisymmetricly distributed, stress equalization during cutting；The basil of the blade is 40 °.The flank of mowing blade two is designed as blade in the present invention, without more allowing blade replacement in side edge wear or after scrapping, as long as hay mover, which is reversely rotated, just can continue mowing, can realize both sides mowing；In the hard thing such as the stone in running into thick grass, branch, mowing blade can be made reversely to flick, it is to avoid collision is broken or flown out and hurts sb.'s feelings, improve blade service efficiency.
Description
(1) technical field
The present invention relates to a kind of disk mower cutter device, belong to agriculture and forestry machinery manufacture field.
(2) background technology
Hay mover is that cutter device is one of its important part for cutting herbage or trimming the machinery of ornamental plant.
Rotary mower category is arranged on rotary head, is rotated under the action of the centrifugal force with cutterhead without supporting cutting, blade
Row cutting herbage, pace is high, and productivity ratio is larger, is not likely to produce clogging, and more allowing blade replacement is simple, easy maintenance.It is this
The disk cutter device of hay mover in the market substantially has two kinds：One kind is that blade is affixed with cutterhead, runs into stone, branch etc.
Hard thing is easily bent or broken, and just directly scraps afterwards, adds the cost of user, and the blade broken may bullet
Open, certain injury is caused to human body；Second is flail knife formula cutter device, and blade rotates, run under the influence of centrifugal force
Barrier can be with resilience, but easily loosens under the circumference of the high-speed rotation, also has certain danger.Blade and cutterhead
Connection is general by the way of being hinged, and this mode can make blade not produce violent chatter when rotating, but be due to above and below blade
Two surfaces are contacted with cutterhead surface, just increase frictional force, reduce blade service life.
(3) content of the invention
To overcome the defect of above-mentioned flail knife formula cutter device, filled the invention provides a kind of cutting of Novel disc hay mover
Put, the cutterhead that this hair is invented is connected with the machine shaft of existing hay mover, rotated at a high speed by machine shaft band movable knife disc；Lean on
Mowing blade is thrown away work by centrifugal force.
A kind of Novel disc hay mover cutter device, including cutterhead, mowing blade, bolt and split pin.
The cutterhead is disc；Cutterhead is connected with machine shaft, is driven and rotated by machine shaft；Along it on the cutterhead
Even circumferential is connected with mowing blade, and the length that each mowing blade outer rim stretches out cutterhead circumferential surface is 55mm；It is described to mow
Blade afterbody is provided with blade afterbody perforate；Mowing blade uses bolt by the movable connection of blade afterbody perforate with cutterhead, cuts
2mm gaps are provided between careless blade and cutterhead；And packing ring is provided between mowing blade and cutterhead；Mowing blade can be rotated with cutterhead
And rotate；Blade, which runs into barrier, reversely to be flicked, it is to avoid collision fracture；The bolt top drilling, for insertion opening pin
Fixing nut.The mowing blade is rectangle, and two flanks of the mowing blade are blade, and two flanks are axisymmetricly distributed,
Stress equalization during cutting；The basil of the blade is 40 °.
It is preferred that, along its circumference at interval of 120 ° of connections, one mowing blade on the cutterhead.
In the present invention, the flank of mowing cutter two is axisymmetricly distributed along its axis, stress equalization when can guarantee that cutting；Blade
The basil is 40 °, and larger upward lifting air-flow can be produced in blade rotary movement so that the grass blade bar that cuts off easily from
Open blade face, it is to avoid produce the situation of grass cuttings accumulation；The flank of mowing blade two is designed as blade, edge wear or report in side
It without more allowing blade replacement after useless, can just continue to mow as long as hay mover is reversely rotated, can realize that both sides are mowed；Mowing blade and cutterhead
Between be provided with gap, in the hard thing such as the stone in running into thick grass, branch, mowing blade can be made reversely to flick, it is to avoid collision is disconnected
Split or fly out and hurt sb.'s feelings, improve blade service efficiency.
(4) illustrate
Fig. 1：Disk mower cutter device structure chart of the present invention.
Fig. 2：Cutterhead and mowing blade attachment structure figure of the present invention.
Fig. 3：Mowing blade structure chart of the present invention.
In figure：1 cutter head center opens axis hole, 2 cutterheads, 3 mowing blades, 4 spring washers, 5 cutterhead edge perforates, 6 bolt tops
Portion's perforate, 7 split pins, 8 bolts, 31 tool point angles, 32 blade afterbody perforates, the flank of 33 blade two.
(5) embodiment
In conjunction with accompanying drawing, the invention will be further described, as shown in Fig. 2 opening axis hole 1, cutterhead 2 including cutter head center, cutting
Careless blade 3, spring washer 4, cutterhead edge perforate 5, bolt top drilling 6, split pin 7.Cutterhead 2 is turned by axis hole 1 and motor
Axle is connected, and mowing blade 3 is connected with cutterhead 2, and blade is rotated at a high speed the centrifugal force produced by cutterhead and driven, and is together revolved with cutterhead
Turn, start weeding.
Three mowing blades 3, each 120 ° of mowing blade interval are arranged along its even circumferential on one cutterhead 2, and is mowed
The length that cutterhead edge is stretched out on the head of blade 3 is 55mm, and when cutterhead 2 rotates at a high speed, mowing blade 3 is thrown out of work, hay knife
The area that piece 3 is inswept reaches that mowing is required, and can maximize mowing efficiency, and reduction is cut again cuts with leakage.
A diameter of 16.2mm of cutterhead edge perforate 5, a diameter of 16mm of bolt 8, is provided between mowing blade 3 and cutterhead 2
Spring washer, and 2mm gaps are left between the two；So that mowing blade 3 can be rotated freely after being arranged on cutterhead 2, meeting
During the hard thing such as stone, branch into thick grass, mowing blade 3 can be flicked reversely, it is to avoid collision fracture and fly out and hurt sb.'s feelings.
After mowing blade 3 and cutterhead 2 being connected with bolt 8, spring washer 4, bolt top drilling is inserted into split pin 7
6, prevent operationally, nut departs from bolt after being loosened because of the rotation of the high speed of mower blade and flown out；Blade and cutterhead surface
It is not directly contacted with, both frictional resistance is less than present cutter device, improves the service life of mowing blade.
In Fig. 3, tool point angle 31 is 40 °, the 35 ° of angles generally used more than present cutter, in the rotary motion of mowing blade 3
Cheng Zhonghui produces larger upward lifting air-flow so that the grass blade bar cut off easily leaves the surface of mowing blade 3, it is to avoid produce grass
Consider the situation of accumulation to be worth doing；The a diameter of 16.2mm of blade afterbody perforate 32, inserts bolt 8 by mowing blade 3 in blade afterbody perforate 32
It is connected with cutterhead 2.Whole mowing blade 3 is regular rectangular shape, and the flank 33 of blade two is distributed for axial symmetry, and in cutting, stress is equal
Weighing apparatus, so that held stationary state.
