Description
Technical field
The present invention relates to united reaper field, the specifically skill of the concave grate of united reaper and notch board screen device
Art.
Background technology
The notch board screen device of united reaper is typically by the fixed plate including frame, little steel column and fixing little steel column
Each concave grate forms, and little steel column is steel bar.The little steel column of existing combine-harvester concave sieve all using round bar, along cylinder
Circumferencial direction bends camber, is through in fixed plate, causes larger along roll circumference direction concave grate gap, long straw easily falls
Enter vibrosieve, in watering and separation procedure, cleannes are not high；Because little steel column is all with round bar, threshing resistance is little, and threshing is not done
Only.
In addition, the notch board screen device of existing united reaper is typically combined using multiple concave grates, but each notch board
There is no between sieve interchangeability, abrasion concave grate faster, need the concave grate more renewing after serious wear, other concave grates may
Scrap to harvester and still will not damage, cause the wasting of resources.
Content of the invention
In order to overcome the deficiencies in the prior art, it is an object of the invention to provide one kind make long straw be difficult to fall into vibrosieve clear
During choosing, strengthen the concave grate of the united reaper of threshing and cleaning ability.
A kind of through threshing is also provided, and there is between each concave grate the concave grate dress of the united reaper of interchangeability
Put.
The present invention is realized by following technical proposals：
A kind of concave grate of united reaper, the frame including both sides it is characterised in that：Solid between the frame of described both sides
Surely it is connected with spaced apart arc fixed plate, each arc fixed plate is matched with the cylinder on harvester, each arc fixed plate
It is parallel to each other between plate face and vertical with the shaft axis of cylinder, each arc fixed plate is equipped with spaced apart square steel bar, phase
It is additionally provided with least one round bar, described square steel bar and round bar are all put down with the shaft axis of cylinder between adjacent described two square steel bars
OK.
Described square steel bar and round bar are detachable installation, and wherein first of the frame near both sides steel bar is circle
Steel bar.
It is welded to connect between the two ends of described each arc fixed plate and corresponding frame, each arc fixed plate directly opens up
There is the jack of each steel bar.
A kind of notch board screen device of united reaper, forms a curved screen by the assembly of aforementioned concave grate.
Described curved screen is semi arch screen cloth, when being four hardened structures, interchangeable between each concave grate, between each concave grate
It is fixedly connected with bolt；Or described curved screen is semi arch screen cloth, when being six hardened structures, can between middle two pieces of concave grates
Exchange, in addition interchangeable between four pieces of concave grates, it is fixedly connected with bolt between each concave grate.
The present invention compared with prior art has advantages below：
1）Steel column in the concave grate of united reaper of the present invention is different from concave grate in prior art all using round steel
Bar, but be round bar, square steel bar by two kinds of steel bars, and the steel bar that is provided with the present invention is all to be through at arc along cylinder direction
In fixed plate, that is, parallel with the shaft axis of cylinder that is, vertical with the circumferencial direction of cylinder, it is linear, therefore all
Steel bar all do not need when making to bend, make very simple, and arc fixed plate can directly be molded into and cylinder in blanking
Shaft axis vertical, that is, consistent with the circumferencial direction of cylinder, erecting and welding is convenient and swift, therefore greatlys save processing cost.
2）Because all steel bars are to be through on arc fixed plate along cylinder direction, so along roll circumference direction, concave grate
Gap little, long straw is difficult to fall into during vibrosieve cleans, and because round bar, square steel bar interaction are staggered, increases
Threshing resistance, particularly square steel bar more enhances threshing resistance, hence in so that threshing and cleaning is better.
3）The notch board screen device of united reaper of the present invention, can between each concave grate due to being formed by the assembly of aforementioned concave grate
Exchange, which decrease frock making cost, decrease harvester use and maintenance cost, improve its value.
Brief description
Fig. 1 is the concave sieve structure schematic diagram of united reaper of the present invention；
Fig. 2 is the structural representation of the concave grate device embodiment 1 of united reaper of the present invention；
Fig. 3 is the structural representation of the concave grate device embodiment 2 of united reaper of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings the concave grate of united reaper of the present invention is further described:
As shown in figure 1, the concave grate of united reaper of the present invention, including the frame 1 of both sides, between the frame of both sides
It is fixedly connected with spaced apart arc fixed plate 2, each arc fixed plate is matched with the cylinder on harvester, each arc fixed plate
Plate face between be parallel to each other and vertical with the shaft axis of cylinder, each arc fixed plate is equipped with spaced apart square steel bar 4,
It is additionally provided with least one round bar 3, square steel bar 4 and the shaft axis all with cylinder for the round bar 3 between adjacent described two square steel bars
Parallel.That is square steel bar 4 and round bar 3 are linear, it is not bending circular arc, is not to bend to along roll circumference direction
