Abstract

The utility model relates to a straw cutting device mated with a threshing before cutting harvester, which comprises components such as a cutting apparatus, conveyor chains with a stirring finger, an upper cover plate, a lower seat plate, a bearing seat, a chain box, etc. The conveyor chains are positioned between the upper cover plate and the lower seat plate, the lower seat plate is fixed on the bearing seat behind the lower seat plate, and the bearing seat is installed above the chain box; drive sprockets which are coaxially rotated with the conveying sprockets are arranged in the chain box, the reciprocating cutting apparatus below the lower seat plate is fixed in front of the chain box, and a longitudinal straw conveying passage is formed between the upper cover plate and the lower seat plate between two adjacent groups of conveyor chains. The utility model has the advantages of simple structure and compact structure, and can match with various threshing before cutting harvesters to realize the associated operation of harvesting seeds and harvesting straws.

Description

A kind of straw cutter sweep that matches with the threshing prior to cutting reaping machine
The utility model is a kind of straw cutter sweep that matches with the threshing prior to cutting reaping machine, belongs to the paddy and wheat harvest machinery.
The threshing prior to cutting reaping machine is a kind of comparatively novel harvest machinery, compares with both at home and abroad existing half feeding, all feeding-in combine, have results efficient height, dependability height, simple in structure, cost is low, low power consumption and other advantages.But existing threshing prior to cutting reaping machine nearly all is not equipped with the straw cutter sweep, the machine farm work is the seed of harvesting crops only, the straw that takes root behind the harvest operation in the ground can't in time be handled, this does not meet the especially farming custom in paddy rice producing region of the most areas of China, if adopt cutter to gather in the second road operation of straw, then because of last one operation road wheel (or crawler belt) overwhelms straw, cutter is failed a straw and is all cut down therefore serious its popularization of restriction and use.The agricultural machinery scientific workers have carried out a large amount of research and development to the straw cutter sweep that matches with the threshing prior to cutting reaping machine, a kind ofly do not increase neither that the machine front-extending quantity can be installed again and straw cutter sweep simple in structure, that result of use is comparatively desirable drops into actual the use in the confined space but still have so far.
The purpose of this utility model provides a kind of straw cutter sweep matching used with it on the multiple threshing prior to cutting reaping machine that be installed in.
The utility model structure is as shown in drawings: it comprises a knife section by standard, reciprocating cutterbar and straw pull-over that ledger-plate and guard constitute combine, it is characterized in that described straw pull-over is provided with is no less than the carrier chain (band) that two groups of bands pull out finger, carrier chain (band) is by carrier chain (band) wheel drive, carrier chain (band) and carrier chain (band) wheel are between upper cover plate and following seat board, upper cover plate is fixed on down the seat board top by bearing pin, following seat board is fixed on the bearing block that is positioned at its rear, bearing block is installed in the chain cover top, be provided with the drive sprocket of taking turns coaxial rotation with carrier chain (band) in the chain cover, the reciprocating cutterbar of seat board below is fixed on the place ahead of chain cover under being positioned at.
Above-mentioned carrier chain (band) surface of revolution of the utility model is level, is evenly equipped with on the carrier chain (band) dial to refer to, dials to refer to that working face is semi-cylindrical and is not less than 110 ° with carrier chain (band) direction of motion angle.
Constituted a parallel i.e. straw transfer passage longitudinally between the upper cover plate of the two adjacent groups that the utility model is above-mentioned and the following seat board with the direction of machine travel, the front end of upper cover plate and following seat board plays the effect of branch standing grain, the rear end can prevent that straw from rewinding, after installing, upper cover plate and following seat board promptly stipulated the service area of group finger to straw
The straw cutter sweep that the utility model is above-mentioned also can be fixed on bearing block and chain cover the top of upper cover plate.
The utility model has the advantages that simple and compact for structure, can in the confined space, install, result of use is good, under the situation that does not increase the machine front-extending quantity can with the supporting use of polytype threshing prior to cutting reaping machine, solved the problem that threshing prior to cutting reaping machine farm work can't in time be handled the straw that takes root behind the grain harvest in the ground, realize once finishing the integration of operation of results seed and harvesting straw, improved work efficiency greatly.
Description of drawings the utility model embodiment:
Fig. 1 is a schematic top plan view of the present utility model,
Fig. 2 is the A-A cross-sectional schematic of Fig. 1,
Fig. 3 is that the B-B of Fig. 1 analyses and observe enlarged diagram,
Fig. 4 is the utility model and the supporting schematic side view of threshing prior to cutting reaping machine.
As accompanying drawing 1, shown in 2, carrier chain (band) 4 surfaces of revolution are level, be evenly equipped with on the carrier chain (band) 4 to dial and refer to 5, the angle of dialling the direction of motion that refers to 5 working faces and carrier chain (band) 4 is not less than 110 °, carrier chain (band) 4 driven by transportation sprocket 3, carrier chain (band) 4 and transportation sprocket 3 are between upper cover plate 1 and following seat board 10, upper cover plate 1 is fixed on down seat board 10 tops by bearing pin 2, following seat board 10 is fixed on the bearing block 6 that is positioned at its rear, bearing block 6 is installed in chain cover 7 tops, be provided with the drive sprocket 8 with transportation sprocket 3 coaxial rotation in the chain cover 7, be positioned at the place ahead that the reciprocating cutterbar 9 of seat board 10 belows down is fixed on chain cover 7.After installing, upper cover plate 1 and following seat board 10 promptly stipulated to pull out the service area that refers to 5 pairs of straws, constituted a parallel i.e. straw transfer passage longitudinally between the upper cover plate 1 of two adjacent groups and the following seat board 10 with the direction of machine travel, the front end of upper cover plate 1 and following seat board 10 plays the effect of branch standing grain, and the rear end can prevent that straw from rewinding.
Dial shown in the accompanying drawing 3 and refer to that 5 working face is a semi-cylindrical.
Threshing prior to cutting workpiece 11 is suspended on the place ahead of rear-engined hand tractor 12 shown in the accompanying drawing 4, and the back lower place that straw cutter sweep of the present utility model is installed in threshing prior to cutting workpiece 11 is the front lower place of driving wheel 13.
The utility model is work like this: after threshing prior to cutting reaping machine and straw cutter sweep of the present utility model are supporting, become the threshing prior to cutting combine, as shown in Figure 4.During machine works, the straw that is purified seed by threshing prior to cutting workpiece 11 combs is forward-lean state, as accompanying drawing 1, straw a shown in 2, along with machine advances, the front end of upper cover plate 1 and following seat board 10 is separated these straws, and then the bottom of straw is transferred pulling out on the chain (band) 4 and refers to that 5 pull over by force along the straw transfer passage of formation between the upper cover plate 1 of two adjacent groups and the following seat board 10 backward, when the base portion of straw touches cutter 9, straw is cut device 9 and cuts off under the supporting of dialling finger 5, as accompanying drawing 1, straw b shown in 2, straw refers to that by dialling 5 continue to carry backward afterwards, until breaking away from body, the root of straw lands earlier, straw along the direction of machine travel be root headfirst after the strip lay, as accompanying drawing 1, straw c shown in 2.
