At least one blade-pressing device is fixed on the upper end of the fixed knife bridge, and presses the movable blades where the blade-pressing device exists onto the corresponding fixed blades, so that the movable knife bridge is limited inside the groove. The lower header assembly of the harvester is safe in use, small in size, capable of protecting a lower cutting knife, simple in structure, good in cutting effect, and easy to operate in repair and replacement. In addition, service life of cutting knives is prolonged, and reliability of products is greatly improved.
Description
Technical field
The utility model relates to the grain header parts, is specially grain header lower cutting table assembly, belongs to mechanical equipment technical field.
Background technology
Grain header is the machinery of a kind of integrated harvesting crops, and it can disposable completion harvesting, threshing, and grain is focused on the repository bag, and then through transmitting manpower grain is turned on the transport vehicle.Existing grain header mainly is made up of engine, transmission system, clutch, manipulation device, belt mechanism and lower cutting table mechanism, and wherein, lower cutting table mechanism is specifically designed to the parts of shearing paddy.But, find that in use the lower cutting table assembly of existing grain header is because structure is comparatively complicated; Cause its volume bigger; Therefore cutter is easy to bump with ground when work under causing, and then causes sharp wear, when particularly in the field hiding stone being arranged; Following cutter is owing to lack effective protection, and it is impaired very risky.In case and cutter is damaged meeting formation breach, this causes upper cutter knife to cut less than grain ear, causes the loss of grain ear.And, because following cutter is damaged formed breach, make lower cutting table collided more easily, this can aggravate the damage of lower cutting table, thereby causes the service life of present lower cutting table assembly generally shorter.And because former following cutter structure limitation, the rice stubble of cutting off is deposited in down and also is unfavorable on the cutter draining.
The utility model content
To above-mentioned deficiency of the prior art; It is higher that the purpose of the utility model is to solve present grain header lower cutting table assembly spoilage; Service life is shorter, and the rice stubble of cutting off is deposited in down and is unfavorable for the problem of draining on the cutter, and provides a kind of safe in utilization; Simple in structure, be beneficial to the grain header lower cutting table assembly of draining rice stubble.
The technical scheme of the utility model is following: grain header lower cutting table assembly, it is characterized in that, and comprise the stationary knife beam that has transverse concave groove, in said groove, be provided with one and can prolong the cutter beams that groove direction is slided; Crosswise fixed has some blocks of ledger-plates on the stationary knife beam, and crosswise fixed has some knife sections on cutter beams; Also be fixed with at least one pressuring blade device in stationary knife beam upper end, said pressuring blade device is limited in cutter beams in the said groove.
Further technical scheme, said pressuring blade device are two and lay respectively at the two ends of stationary knife beam.
Further again, between pressuring blade device and stationary knife beam, also be provided with the adjustment pad.
With respect to prior art, the utlity model has following beneficial effect:
1, use is safer, has reduced spoilage: the lower cutting table assembly of the utility model is owing to the structure that adopts stationary knife beam and cutter beams that blade is installed respectively, and volume is littler, and particularly the convexity of the bottom portion of groove of stationary knife beam formation makes the intensity of stationary knife beam strengthen greatly.The spacing on cutter and ground under can increasing like this can play a protective role to following cutter again, has alleviated the wearing and tearing of cutter to a certain extent.
2, structure is simpler, and shear effect is good, and operation is also easier during maintain and replace.
3, prolonged the service life of cutter, reduced user's maintenance cost, reliability of products has obvious lifting.
4, help the rice stubble that is deposited in down on the cutter is drained, prevent to stop up.Since traditional cutter pattern knife section down, cutter beams is last, can cause harvesting moving ahead, the rice stubble after cutting off like this can stand in the cutter beams place, not shuttle backward; And the utility model adopts cutter beams down, and knife section is in last cutter pattern, and like this because there is not cutter beams to block in the above, the rice stubble after cutting off can stand in the cutter beams place, and shuttle is backward drained the smooth and easy of ten minutes just.

Among the figure, 1-stationary knife beam, 2-cutter beams, 3-groove, 4-ledger-plate, 5-knife section, 6-pressuring blade device, 7-adjustment pad.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As depicted in figs. 1 and 2; The grain header lower cutting table assembly of the utility model comprises the stationary knife beam 1 that has transverse concave groove 3, and stationary knife beam 1 is an elongate in shape; One convexity is formed on the bottom of this groove 3; In said groove 3, be provided with one and can prolong the cutter beams 2 that groove direction is slided, cutter beams 2 laterally arranges with stationary knife beam 1, and cutter beams 2 is connected with drive disk assembly through universal driving shaft.Crosswise fixed has some blocks of ledger-plates 4 on stationary knife beam 1, and crosswise fixed has some knife sections 5 on cutter beams 2, and ledger-plate all is positioned at the below of knife section.Also be fixed with two each and every one pressuring blade devices 6 in stationary knife beam 1 upper end, said pressuring blade device 6 lays respectively at the two ends of stationary knife beam 1.During installation, pressuring blade device 6 is pressed in the knife section of its position on the corresponding ledger-plate, and makes cutter beams 2 be limited in the said groove 3, and cutter beams 2 just can not come off when sliding like this.For reducing wearing and tearing, between pressuring blade device 6 and stationary knife beam 1, also be provided with adjustment pad 7.In the utility model, the effect of pressuring blade device 6 is to limit cutter beams 2 the moving of short transverse, and it can only be moved back and forth transverse concave groove 3 in, and the distance between assurance knife section and the ledger-plate is constant, so that cut.Cutter beams 2 is connected with the power set of grain header, and cutter beams moves back and forth in transverse concave groove under power set drive, and just forms shear action like this between knife section and the ledger-plate, cuts off crops.
In the utility model, for easy for installation, ledger-plate and knife section are all fixed through rivet, certainly, also can adopt other connected modes such as screw, and said pressuring blade device 6 is through being bolted on the stationary knife beam, and fastening with nut.
During work; The power of grain header flows to cutter beams 2 through drive disk assembly; Make cutter beams produce horizontal reciprocating motion, the knife section on the cutter beams also produces traverse motion, because stationary knife beam and ledger-plate all are fixed; Therefore between ledger-plate and knife section, just produce shearing force, formed the action of shearing.In the utility model,, therefore can play a protective role, avoid the touching of ledger-plate and ground, thereby prolong the service life of lower cutting table ledger-plate because convexity has been formed on the bottom of stationary knife beam upper groove.
Need to prove; Above embodiment is only in order to explain the utility model technical scheme but not the restriction technologies scheme; Although the applicant specifies the utility model with reference to preferred embodiment, those of ordinary skill in the art should be appreciated that those technical schemes to the utility model make amendment or be equal to replacement; And do not break away from the aim and the scope of present technique scheme, all should be encompassed in the middle of the claim scope of the utility model.
