Abstract
The utility model relates to a grain threshing combine harvester belonging to the agricultural machine. The utility model is characterized in that the involute gears which are arranged in pairs and the flexibility threshing belts which are embedded with threshing teeth are formed into the threshing mechanism, the cutting device comprises a flexibility cutting belt which is embedded with cutting knives, and the straw gripper mechanism is saved because the threshing is preferential and the cutting is last. The utility model has the advantages of structure simplifying, good effect, wide cutting length, stable cutting and high efficiency, and is in particular be suitable for the reaping of the paddy rice.
Description
A kind of agricultural machinery, the grain threshing combine.
Existing grain combine all is cutting back threshing earlier, separate and clean etc., its cutter sweep has reciprocating type and garden disc type two classes, reciprocating type is that knife section is made reciprocal cutting movement with respect to the ledger-plate on the guard, place the straw between blade to be broken by blade, because blade moves back and forth inertia and the shock loading that produces, and is influential to the life-span of installing each parts, must carry out inertia balance.The disc type cutter sweep is to do gyration, vibrates for a short time, but swath is limited by disk diameter, seldom adopts at present.
The sheller unit of existing grain combine can be divided into full feeding type and half feeding type by crop feeding mode, its version mainly is drum-type, cereal enters between cylinder and notch board from feeding mouth, and cylinder is done to continue gyration, with notch board cereal is carried out threshing.
The mode of threshing is again cut by existing elder generation, if adopt full feeding, then crop cane and fringe portion together enter thresher, and threshing efficiency is relatively low, and power consumption is big, if adopt half feeding then must adopt special cutting, and complex structure, operating speed is slower.Full feeding or half feeding so long as cutting back threshing earlier all will be provided with special clamping device, make combine structure more complicated.
The purpose of this utility model is to simplify the structure of combine, improves operating efficiency.
The grain threshing combine of the utility model design; separating mechanism and cutter sweep are arranged; it is characterized in that separating mechanism includes mounted in pairs; direction of rotation; size is identical; rotate at grade, and the involute gear that overlaps ［ 3 ］ is with parallel with involute gear (3), thereunder and be embedded with the flexible threshing band (5) of steel wire threshing tooth (6).Cutter sweep comprises that assembly has the flexible cutting belt (28) of cutter (27).
Below in conjunction with description of drawings:
Fig. 1, Fig. 2 are the separating mechanism installation drawing of grain threshing combine, involute gear (3) mounted in pairs, equal and opposite in direction.Switched in opposite, rotate at grade, involute gear (3) top taper, root is thicker, gear teeth root is equipped with the prevent cereal concentric with it and enters the garden ring (13) of root, distance between a pair of involute gear (3) is greater than its external diameter, involute gear (3) is driven by driving shaft (1), driving shaft (1) is a steel ladder garden axle, be contained on supporting (11) and (12) by bearing, driving shaft (1) is tightened together by nut (2) with involute gear (3), and supporting (11) and supporting (12) fuse with the fuselage of threshing combine, and be parallel to each other between the driving shaft (1).
The flexible threshing band (5) parallel with its plane of rotation is housed below the involute gear (3), be embedded with the flexible belt of steel wire threshing tooth (6) above being, flexible threshing band (5) is driven by garden shape driving wheel (7), and be contained on the garden shape driven pulley (4), driving wheel (7) is driven by wheel shaft (14), and the shape size structure of driven pulley (4) and driving wheel (7) are just the same.
Below the flexible threshing band (5) cereal conveyer belt (10) is housed, conveyer belt (10) is driven by driving wheel (9), can be made by high strength canvas or nylon cloth, in order to take away the cereal-granules that falls from flexible threshing band (5).
Fig. 3 is the cutter sweep figure of grain threshing combine, flexible cutting belt (28) upward connects or rivets some by the screw thread connection can be the cutter ［ 27 ］ of steel disc or iron plate, flexible cutting belt ［ 28 ］ is driven by driving wheel ［ 26 ］, driving wheel ［ 26 ］ is fastened on the driving shaft ［ 15 ］, be contained in supporting ［ 17 ］ by bearing, ［ 23 ］ on, driven ［ 30 ］ of locating flexible cutting belt ［ 28 ］ are fastened on the driven shaft ［ 34 ］, be contained on supporting ［ 35 ］ and ［ 36 ］ by bearing, the trapezoidal adhesive tape ［ 18 ］ that dogstail that steel wire makes is removed bar ［ 29 ］ evenly is housed, ［ 21 ］ with ［ 24 ］ and the parallel top that places flexible cutting belt ［ 28 ］ of flexible cutting belt ［ 28 ］, go up the belt drives wheel ［ 19 ］ of band dovetail groove by being fastened on driving shaft ［ 15 ］ respectively, ［ 22 ］ and ［ 25 ］ drive, while trapezoidal adhesive tape ［ 18 ］, ［ 21 ］, ［ 24 ］ the other end is loaded on respectively, be fastened on the driven shaft ［ 34 ］ and the belt driven pulley ［ 31 ］ of the duplicate band dovetail groove of belt drives wheel construction, ［ 32 ］ and on ［ 33 ］.
Fig. 4 is grain threshing combine separating mechanism and cutter sweep location diagram; separating mechanism is before cutter sweep; cereal ［ 8 ］ is earlier through the separating mechanism threshing; dogstail after the threshing ［ 38 ］; rely on cutter sweep with advancing of grain header; after being cut off by cutter near the dogstail ［ 37 ］ of cutter ［ 27 ］, be eliminated bar ［ 29 ］ and take away.
The grain threshing combine of the utility model design, cut behind the early threshing, saved the straw clamping device that general combine all has, made grain header simplify flexible threshing band and flexible cutting belt, threshing, cutting is steady, and swath is wide, and operation is convenient, be applicable to the harvesting of various cereal, especially convenient to paddy rice harvesting.
