Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
This patent adopts board-like separating mechanism as shown in Figure 1 to replace traditional drum type brake or crawler type separating mechanism, significantly can reduce the bulk of grain separating mechanism.Separating mechanism as shown in Figure 1, upper frame 1 is the main frame structure of separating mechanism, and the transverse direction of upper frame 1 installs roller bearing 2, and shelling roller bearing 2 being welded S type is followed closely shown in 3(Fig. 2).It is interleaved that shelling between adjacent roller bearing 2 follows closely 3 lateral attitudes, makes roller bearing 2 spacing compacter, the layout of shelling nail 3 evenly, thus better ensure the separative efficiency of grain.Synchronous pulley 4 is installed in one end of roller bearing 2, and synchronous pulley 4 drives by Timing Belt 5 is unified, and is together driven by minor sprocket 6.Synchronous pulley 4, minor sprocket 6 are be rigidly connected by flat key (not shown) with roller bearing 2, when minor sprocket 6 rotary motion, together drive coaxial roller bearing 2 and Timing Belt 5 to take turns to rotate, synchronous pulley 4 drives again the motion of other synchronous pulley 4 by Timing Belt 5, also be all realize being rigidly connected by flat key between synchronous pulley 4 and roller bearing 2, the shelling nail 3 on other roller bearing 2 therefore driven again and roller bearing 2 rotates together.When above paddy rice is placed on, shelling nail 3 just curries paddy rice, thus realizes grain and separate from stem stalk.
Fig. 3 is that driving mechanism structure schematic diagram is ridden in the adjustable energy storage of intermediate cam of the present invention, goes out as shown in Figure 3, and because this threshing machine is collapsible, and employing is chain wheel drive, and chain will be installed and unload frequently, therefore requires that sprocket wheel installation and removal are efficient and convenient.What grain separating mechanism adopted simultaneously is roller bearing, and the inertia force that rotary operation process provides is limited, therefore needs to ensure that roller bearing can realize rotating continuously by other means.Based on requiring that this patent devises the adjustable energy storage pedal drive mechanism of triangle as shown in Figure 3 above.This mechanism adopts foot-operated drive scheme, and people drives the fulcrum of foot-driven lever 8 on support 9 to move up and down by trampling pedal 7, thus drives hinge wheel 10 to rotate.Hinge wheel 10 to be rigidly fixed with rotating shaft 11 by flat key and is connected, and is placed on installing plate 13 by bearing and bearing block 12.The stability triangle support structure that installing plate 13 is consisted of support bar 14 and support bar 15.Support bar 14 and support bar 15 are arranged on support 16 and support 9 respectively by the mode be movably hinged, and remain with one degree of freedom respectively, and support bar 14 and support bar 15 can provide stable gusseted with coaxial link of rotating shaft 11.
Support bar 14 and support bar 15 are made up of the two sections of support bars and intermediate thread cover of being with self-locking thread again respectively, during turn intermediate thread cover, two sections of threaded support bars just can be driven easily inwardly or outwards to move simultaneously, thus the length of adjustment support bar, and then realize the adjustment of installation site of hinge wheel 10.
Energy-stored spring 17 and connecting rod 18 are arranged on the fulcrum 19 on hinge wheel 10 jointly, and hinge wheel 10 makes clockwise rotation, and when fulcrum 19 arrives the right side of installing plate 13, people tramples the elongation that pedal 7 drives hinge wheel 10 motion and energy-stored spring 17 downwards; When fulcrum 19 is to the left side of installing plate 13, the pin of people does not apply power, by the restoring force of inertia force and energy-stored spring 17, makes hinge wheel 10 continue to do continuous print rotary motion; When fulcrum 19 arrives the right side of installing plate 13, the pin of people is trampled downwards again, iterative cycles, ensures working continuously of threshing machine.
Fig. 4, Fig. 5 be threshing machine of the present invention from the procedure chart folding into expansion, wherein Fig. 4 is the threshing machine of folding carrying and storage configuration, making layout very compact, taking up room and significantly reducing by folding.Fig. 5 is the threshing machine of deployed condition, and upper and lower expansion turns over turnback by the hinge 21 be arranged on upper frame 1 and underframe 20 crossbeam to realize, and locked after upset puts in place by latch 22.Fig. 6 is the threshing machine after launching driving mechanism and laying pin support.The left and right upset of driving mechanism is turned over by the hinge 23 be arranged on underframe 20 and driving mechanism and is turn 90 degrees realization, is locked equally after upset puts in place by latch 24.Upper support bar 25 is directly connected through the hinge with feet 28 with upper frame 1, lower support bar 26, respectively remains a rotary freedom, to adapt to the support of different angles.There is screw thread the lower end of upper support bar 25 and the upper end of lower support bar 26, and the adapter sleeve 27 of centre is also helicitic texture, by being with the helicitic texture of self-locking to connect upper and lower support bar 25,26, can adjust the length of support bar very easily.Fig. 7 launches in running order threshing machine completely.The entirety of threshing machine is laid gradient and is determined by the length of supporting traverse 29, adjusts as required.The hinge wheel 10 of driving mechanism is connected by chain with the minor sprocket 6 on upper frame 1, and the other end of the energy-stored spring 17 of hinge wheel 10 is arranged on supporting traverse 29, and unclamping of chain is realized by adjustment driving mechanism support bar length with tensioning.Launch the shelling function that also mounting and adjusting is good and well complete efficient threshing operations.
The explanation of above example just understands core concept of the present invention for helping; Meanwhile, for one of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
