Description
Technical field
The utility model is related to harvester part fields, more specifically to a kind of harvester blade.
Background technology
Application of the combine harvester in modern agriculture is more and more common, especially rice, and the harvesting of rice uses rice
The area of harvester has accounted for 80% of Monitoring of Paddy Rice Plant Area or more.And rice harvester is during the work time, is easiest to
One component of abrasion is exactly blade, and the hard object such as stone, tree root is encountered in cutting process makes guard loosen or deform, stationary knife
Piece height is inconsistent；And blade loosing of rivet, when cutting, which collides etc., may all cause cutting blade to damage.There is a kind of rice harvesting
Machine knife blade, it is steel-casting which, which has trapezoidal cutting edge portion and the mounting portion with the quadrangle of blade connection, the blade, is led to
Often to the processing method of this blade can be used after putting the first edge on a knife or a pair of scissors mouth and sharpening mouth.This blade on rice harvester exists
There are the following problems during use：It is easy to burst apart when blade encounters stone or hard object, breaks down is caused to be scrapped.
The cambered blade of existing harvester is mostly that two or more pieces of blade splicing is welded, since welding technique is asked
Topic, firm welding degree and welding precision are insufficient, be easy to cause blade and fracture when in use, and due to existing arc
Blade is mostly the sharp edge of a knife, easy to wear and wiredrawn edge, and cut substrate is easy to be stuck on blade, needs to be replaced as often as possible, production effect
Rate is low, of high cost.For the situation of existing blade strength deficiency, the prior art is also correspondingly improved.
Chinese patent application, application number 201410304581.8, disclose a kind of rice at publication date on October 15th, 2014
Harvester blade and processing method, are related to technical field of mechanical processing, rice harvesting machine knife blade, have pre-small post-large trapezoidal
The mounting portion in cutting edge portion and the quadrangle linked with the blade, is distributed with jagged on the trapezoidal bevel edge in the both sides in cutting edge portion
Tooth；The processing method of rice harvesting machine knife blade, includes the following steps：By the blank of blade by forging, milling, heat treatment, depth
Rice harvesting machine knife blade is obtained after cold treatment and grinding.Compared with prior art, the invention has higher intensity, plasticity and tough
Property, it not only can be with cutting rice stalk, while small-sized brick and stone can also be shredded, it solves when blade encounters hard object and is easy to make
Lead to scrap problem at bursting apart, prolongs the service life.But this scheme is mainly improved from material, and improving cost is high, knot
Structure is complicated, needs to be replaced as often as possible.
Invention content
1. technical problems to be solved
It for existing in the prior art complicated, quick abrasion, needs to be replaced as often as possible, low production efficiency is of high cost
Problem, the utility model provide a kind of harvester blade.There is intensity height, long lifespan to replace few, the at low cost effect of number for it
Fruit.
2. technical solution
The purpose of this utility model is achieved through the following technical solutions.
A kind of harvester blade, including blade, wherein blade are integrally formed by main body blade and cutter head blade, main body blade
Arc-shaped, cutter head blade is in integral curved, and lower part is plane, and blade is integrally arc-shaped, and cutter head is set to cutter head blade end,
Cutter head blade forms cut end with cutting edge.
Further, cutter head end is arc-shaped.Arc-shaped edge of a knife intensity is more preferable, and the feelings of wiredrawn edge are less likely to occur
Condition.
Further, in up big and down small trapezoidal, trapezoidal both sides inclined-plane is blade inclined-plane on main body blade top.Reserve two
The space on side provides the position of installation, also improves the intensity of overall theme blade.
Further, several mounting holes are provided on main body blade, mounting hole is waist hole.
Further, cutter head upper surface is provided with alloy-layer.Alloy-layer so that the edge of a knife is more wear-resisting, intensity bigger, the longevity
Life greatly enhances.
Further, the alloy layer thickness is 250-300um.
Further, alloy-layer is formed by powder metallurgy powder spray welding.Alloy material is general metal powder alloy
, at low cost, simple for process, spraying is convenient.
Further, blade material is 65# manganese steel, and intensity is high, is easily worked, at low cost.
3. advantageous effect
Compared with the prior art, the utility model has the advantage of：
(1) this programme carries out bending using one block of manganese steel, and one-pass molding vane body avoids the Welder of cambered blade
Skill is also avoided since intensity caused by welding is insufficient, and integral knife blade intensity is high, at low cost, saves material, longer life expectancy；
(2) in up big and down small trapezoidal, trapezoidal both sides inclined-plane is blade inclined-plane on main body blade top.Reserve the space on both sides
The position for providing installation also improves the intensity of overall theme blade；
(3) cutter head upper surface is provided with alloy-layer, and alloy-layer is formed by powder metallurgy powder spray welding.Alloy material is general
Metal powder alloy, at low cost, simple for process, spraying is convenient, and alloy-layer so that the edge of a knife is more wear-resisting, intensity bigger,
Service life greatly enhances.

Specific implementation mode
With reference to the accompanying drawings of the specification and specific embodiment, the utility model is described in detail.
Embodiment 1
As shown in Figs 1-4, a kind of harvester blade, including blade 1, wherein blade 1 is by main body blade 101 and cutter head blade
102 are integrally formed, and main body blade 101 is arc-shaped, and cutter head blade 102 is in integral curved, and lower part is plane, and blade 1 is whole to be in
Arc, cutter head 2 are set to 102 end of cutter head blade, and cutter head blade 102 forms cut end with cutting edge 104.1 material of blade is 65#
Manganese steel.One block of manganese steel carries out bending, and one-pass molding vane body avoids the welding procedure of cambered blade, also avoid due to
Intensity caused by welding is insufficient, and integral knife blade intensity is high, at low cost, saves material, longer life expectancy.Blade can when bending
To there is certain gradient, can integrally making the sundries accumulated when harvesting in arcwall face, there are one slanting power, by oblique
Face exports, will not be stuck.
2 end of cutter head of this programme is arc-shaped, and is not traditional tip cutter head, 101 top of main body blade present it is big under
Small is trapezoidal, and trapezoidal both sides inclined-plane is blade inclined-plane 103.Main body blade top is in up big and down small trapezoidal, trapezoidal both sides inclined-plane
For blade inclined-plane, the setting on inclined-plane can make the space that blade reserves both sides provide the position of installation, also improve whole master
