Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
This patent adopts board-like separating mechanism as shown in Figure 1 to replace traditional drum type brake or crawler type separating mechanism, can significantly reduce the bulk of grain separating mechanism.Separating mechanism as shown in Figure 1, the main frame structure that upper frame 1 is separating mechanism, the horizontal installation roller bearing 2 of upper frame 1, is welding the shelling of S type and is following closely shown in 3(Fig. 2 on roller bearing 2).It is interleaved that the shelling that adjacent roller bearing is 2 is followed closely 3 lateral attitudes, makes roller bearing 2 spacing compacter, and the layout of shelling nail 3 is more even, thereby better guarantee 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 to be rigidly connected by flat key (not shown) with roller bearing 2, when minor sprocket 6 rotatablely moves, together driving coaxial roller bearing 2 and Timing Belt 5 to take turns rotates, synchronous pulley 4 is driving again the motion of other synchronous pulley 4 by Timing Belt 5, between synchronous pulley 4 and roller bearing 2, be all also to be realized and being rigidly connected by flat key, other roller bearing 2 therefore driving again and the nail of the shelling on roller bearing 23 rotate together.In the time of above paddy rice is placed on, shelling nail 3 just curries paddy rice, thereby realize grain, from stem stalk, separates.
Fig. 3 is the foot-operated driving mechanism structure schematic diagram of the adjustable energy storage of the utility model intermediate cam, go out as shown in Figure 3, because this threshing machine is collapsible, and employing is chain wheel drive, chain will be installed and unload frequently, therefore requires sprocket wheel installation and removal efficient and convenient.What simultaneously grain separating mechanism adopted is roller bearing, and the inertia force that rotary operation process provides is limited, therefore need to guarantee by other means that roller bearing can realize continuous rotation.Based on requiring above this patent to design the adjustable energy storage pedal drive mechanism of triangle as shown in Figure 3.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, thereby drives hinge wheel 10 to rotate.Hinge wheel 10 is rigidly fixed and is connected with rotating shaft 11 by flat key, and is placed on installing plate 13 by bearing and bearing block 12.The stability triangle support structure that installing plate 13 consists of support bar 14 and support bar 15.Support bar 14 and support bar 15 are arranged on respectively on support 16 and support 9 by the mode being movably hinged, and remain with respectively one degree of freedom, support bar 14 and support bar 15 and the coaxial gusseted that can provide stable that links of rotating shaft 11.
Support bar 14 and support bar 15 are comprised of two sections of support bars with self-locking thread and intermediate thread cover respectively again, during turn intermediate thread cover, just can drive easily two sections of threaded support bars inwardly or outwards to move simultaneously, thereby adjust the length of support bar, and then realize the adjustment of the installation site of hinge wheel 10.
Energy-stored spring 17 is arranged on the fulcrum 19 on hinge wheel 10 jointly with connecting rod 18, and hinge wheel 10 is made 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 motions and energy-stored spring 17 downwards; When fulcrum 19 arrives the left side of installing plate 13, people's pin does not apply power, by the restoring force of inertia force and energy-stored spring 17, makes hinge wheel 10 continue to do continuous rotatablely moving; When fulcrum 19 arrives the right side of installing plate 13, people's pin is trampled downwards again, and iterative cycles guarantees working continuously of threshing machine.
Fig. 4, Fig. 5 be the utility model threshing machine from folding into the procedure chart of expansion, wherein Fig. 4 is the threshing machine of folding carrying and storage configuration, by folding, makes layout very compact, takes up room and significantly reduces.Fig. 5 is the threshing machine of deployed condition, and upper and lower expansion is to turn over turnback and realize by being arranged on hinge 21 on upper frame 1 and underframe 20 crossbeams, after upset puts in place, by latch 22, locks.Fig. 6 is for launching driving mechanism and laying the threshing machine after pin supports.The left and right upset of driving mechanism is turned over and is turn 90 degrees realization by being arranged on hinge 23 on underframe 20 and driving mechanism, after upset puts in place, locks equally by latch 24.Upper support bar 25 is directly connected through the hinge with feet 28 with upper frame 1, lower support bar 26, and each has retained a rotary freedom, to adapt to the support of different angles.There is screw thread the upper end of the lower end of upper support bar 25 and lower support bar 26, and middle adapter sleeve 27 is also helicitic texture, by the helicitic texture with self-locking, connects upper and lower support bar 25,26, can adjust very easily the length of support bar.Fig. 7 is for launching in running order threshing machine completely.The integral body 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 with tensioning of chain realizes by adjusting driving mechanism support bar length.Launch and the shelling function of adjusting be installed well to complete efficient threshing operations.
The utility model threshing machine, when actual job, can be installed enclosing on upper frame 1, underframe 20, upper support bar 25, lower support bar 26, to prevent splashing of grain and stem stalk fragment; Can protective cover be installed in motive position, to protect motive position simultaneously.
The explanation of above example is just for helping to understand core concept of the present utility model; , for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model meanwhile.
