Abstract
A double cutter blade device of a combine harvester relates to a combine harvester. A main cutter blade is arranged at the front part of a cutting table and an auxiliary cutter blade is arranged at the rear part of the cutting table; the auxiliary cutter blade is movably fixed at the rear part of the cutting table by a cutter blade rack. Besides, the auxiliary cutter blade is arranged at the lower part of a conveying drum and is fixed on the cutter blade rack; a lift frame is arranged on the cutter blade rack and is provided with fixing holes. The utility model has the advantages that firstly, the main cutter blade is separated from the auxiliary cutter blade and the auxiliary cutter blade can be lifted, thus the straw stubble height can be manually controlled; the load of the combine harvester is effectively reduced; the oil consumption is reduced and the harvest efficiency is increased; secondly, the auxiliary cutter blade can be lifted or dismounted, thereby the use of a single cutter blade or double cutter blades is convenient; thirdly, the service life of the grain threshing machine of the harvester is prolonged; fourthly, the intertwinement and the blockage of a cutting table spiral conveyer, a conveying drum and a grain threshing roller are avoided; and fifthly, the device is easy to manufacture, low in cost and easy to promote.
Description
Technical field:
The utility model relates to agricultural machinery, further is combine, especially for two cutter devices of the combine of grain harvest.
Background technology:
Grain combines such as wheat in the market, paddy are single cutter structure mostly, when work the bar cauline leaf of the wheat rice of cutting off are all fed thresher, have increased the weight of its load; For alleviating the load of thresher, improve harvesting efficiency, often cutter to be raised, gather in stalk as few as possible.If but cutter is lifted higherly, institute's stalk stubble that stays is longer, can influence later farming and field management.
In some documents, also relevant for the data of two cutter combines, but two cutteves of its proposition are operators with secondary cutter one, and two cutteves place the front portion.Like this when grain header gathers in, can do the effect that pushes away before the deposits yields to harvesting, thus the influence harvesting.When not using, be not easy to removal.
Summary of the invention:
The purpose of this utility model just provides a kind of two cutter devices of combine, and its main cutter separates with secondary cutter, and secondary cutter liftable, thereby can gather in easily, alleviates the grain header load, improves harvesting efficiency.
The purpose of this utility model realizes by following scheme: two cutter devices of combine, the front portion of the ceding of Taiwan is equipped with main cutter, it is characterized in that: at ceding of Taiwan rear portion secondary cutter is installed also.
The purpose of this utility model also can further realize by following scheme:
Secondary cutter is installed on the transport tube bottom.
Secondary cutter is fixed on the cutting tool, is fixed with on the cutting tool on the crane, and crane is provided with fixing hole.
Side at cutting tool is provided with drive D, and drive D is connected with drive B outboard wheel by belt, and drive B is coaxial with screw feeder, and drive D drives around the pendulum case, drives the operation of secondary cutter around the pendulum case.
Also be provided with reinforced pole between crane and the cutting tool.
The utlity model has significant effect: 1, take major-minor cutter separate type, secondary cutter liftable both can artificially have been controlled the height of stalk stubble, can also alleviate the grain header load effectively, reduced oil consumption, improved harvesting efficiency; 2, secondary cutter can rise or removal, thereby conveniently is used for the various situations of single cutter and two cutteves; 3, can prolong the service life of thresher machine in the grain header; 4, avoid the winding and the obstruction of ceding of Taiwan screw feeder, transport tube and thresher drum; 5, make simply, cost is low, easily promotes.
Description of drawings:
Fig. 1 faces structural representation for the utility model; Fig. 2 is the right TV structure schematic diagram of the utility model ceding of Taiwan and cutter.
Embodiment:
Below in conjunction with embodiment the present invention is done further narration:
Embodiment 1: as Fig. 1, shown in Figure 2, combine harvester cutting table 1, be prior art, by dialling straw, screw feeder, cutteves etc. are formed, the front portion of the ceding of Taiwan is equipped with main cutter 2, cutter can be selected prior art such as reciprocating cutterbar for use, drive mechanism can adopt following design: a side of the ceding of Taiwan is provided with drive A3, drive A is coaxial with screw feeder, places an end of screw conveyor shaft, and drive A outside is provided with coaxial drive B4, drive B is divided into nearside wheel and outboard wheel, drive B nearside wheel drives drive C5 by belt (or chain), and drive C drives around pendulum case (guide rod), drives the operation of main cutter around the pendulum case.Ceding of Taiwan rear portion connects transport tube 6 (be used for carry to thresher the wheat head etc.); at ceding of Taiwan rear portion, the transport tube bottom also is equipped with secondary cutter 7; secondary cutter is fixed on the cutting tool 8; side at cutting tool is provided with drive D9; drive D is connected with drive B outboard wheel by belt; drive D drives around pendulum case 10, drives the operation of secondary cutter around the pendulum case.Be fixed with on the cutting tool on the crane 11, crane is provided with fixing hole 12, also is provided with reinforced pole 13 between crane and the cutting tool; Be provided with support pull bar 14 between ceding of Taiwan rear portion and crane, support pull bar two ends are fixing by the axle activity, and the middle part is a screw mandrel, by adjusting screw mandrel, can regulate the tightness of support pull bar, thereby can keep the elasticity of belt, can guarantee the steady of secondary cutter simultaneously.
Fixing hole is fixed in the transport tube side by screw, fixing hole for longitudinally several, the hole that the fixed position is different has determined the height of secondary cutter position, thus the length of decision harvesting crops straw.
When need not be with secondary cutter, secondary cutter can be unloaded or rise to the extreme higher position, it does not influence the normal operation of main cutter.
The utility model can adopt manual mode to promote secondary cutter; For ease of the lifting of secondary cutter, forms such as screw mandrel, strand roller, hydraulic pressure also can be set, promote secondary cutter.
All the other each parts of combine such as engine, delivery chute, thresher etc. are not repeated all by prior art.
During work, main cutter is sent into the thresher threshing after wheat, spike of rice are cut off, and secondary cutter cuts off the back to remaining bar cauline leaf and throws go back to the field.Adjust the height of secondary cutter, with regard to the height of controlled straw (rice straw) stubble.
Owing to the existence of two cutteves, can select to promote the height of main cutter, be used to cut the shorter stalk of wheat head portion, thereby reduce the feed quantity of thresher; And secondary cutter cuts remaining stalk, thus controlled wheat stubble height.Because the stalk that enters thresher is less, so just alleviated the load of combine thresher, can avoid the winding and the obstruction of ceding of Taiwan screw feeder, transport tube and thresher drum, can also cut out and meet the field that the peasant wants and cut stubble.In general, the operating efficiency of grain header can improve more than 1/3 at least, even can improve 1 times.
The major-minor cutter of embodiment can be selected light-duty reciprocating cutterbar for use, also can adopt disc cutter or other cutters.
The utility model can be used for the harvesting of crops such as wheat, paddy.
