Description
Technical field
The utility model relates to a kind of farm machinery that removes shell, relates in particular to the transmission device of hand gear electric windmill.
Background technique
Windmill is traditional agricultural working machine, when being mainly used in the cereal crop results, seed is carried out removal of impurities, selected.Use to such an extent that be manpower electric dual-purpose formula windmill the most widely at present in vast rural area, it can adopt motor on the one hand is that power drives the blade rotation, also can adopt the hand drive blade rotation of manpower on the other hand as required.Though this farm implements are simple in structure, cheap, durable in use, rotating disk drove rotatingshaft by belt and belt pulley when but manpower was hand, and belt is positioned at the outside of windmill housing, does not meet the requirement of safety operation, tong causes user's hand injured easily; Simultaneously, belt transmission easily causes kinetic equation loss, and hand like this operation is required great effort very much, and labor intensity was bigger when the user adopted manual operation, and work efficiency is lower.
The model utility content
Technical problem to be solved in the utility model is to provide that a kind of manual operation is light, labour-saving hand gear electric windmill transmission device.
The technical solution of the utility model is as follows: a kind of hand gear electric windmill transmission device, blade is installed by support in middle part at transmission shaft, the two ends of transmission shaft are installed on the left and right frame by bearing and bearing box, fixed motor on left frame, be set with first gear on the output shaft of this motor, first gear is meshed with second gear on the transmission shaft, its key is: the right side in described right frame is provided with rotating disk, this rotating disk is the disk-like structure that has internal tooth, and the 3rd gear engagement on the internal tooth of rotating disk and the transmission shaft; The middle part of described rotating disk is bearing on the little axle by bearing, and little axle passes the bar hole on the cantilever, and by nut check, and cantilever is fixed on the right frame.
The utility model can be by manpower hand or motoring drive the blade rotation.When adopting manpower hand, the user manually controls rotating disk around little axle rotation, in the time of dial rotation, drive the rotation of the 3rd gear by its internal tooth, transmission shaft rotates with the 3rd gear, and drives the blade rotation, this moment, second gear driven, first gear made the output shaft idle running of motor.When needs adopt motoring, at first unclamp the locking nut of little axle, adjust locking again behind the position of little axle in the cantilever bar hole, rotating disk moves with little axle, the internal tooth of rotating disk separates with the 3rd gear, connect the power supply of motor this moment, makes motor operation, and the output shaft of motor drives the rotation of first gear, first gear rotates by the second gear driven transmission shaft, blade is rotated with transmission shaft, and the idle running of the 3rd gear, it is static that rotating disk keeps.
The utility model is owing to adopt gear transmission, and the loss of power is little, and hand like this operation is light, laborsaving, can effectively reduce user's labor intensity, has improved work efficiency greatly; When adopting motoring, the gear of all rotations all is hidden in the windmill housing, and Security is good, can effectively prevent injury to personnel.
For the ease of operation, more laborsaving, be provided with journal stirrup at the edge of above-mentioned rotating disk, on this journal stirrup handle is installed, handle and rotating disk are perpendicular.
Beneficial effect: the utility model is as the improvement of manpower electric dual-purpose formula windmill, have design ingenious, implement easily, light laborsaving, the characteristics such as Security is good of operation, be suitable for the large-scale promotion use.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model is made of parts such as transmission shaft 1, support 2, blade 3, left frame 4, right frame 5, motor 6, first gear 7, second gear 8, the 3rd gear 9, rotating disk 10, little axle 11, cantilever 12, nut 14, journal stirrup 15 and handles 16, wherein blade 3 is arranged in windmill housing (figure does not draw), and is fixed on the middle part of transmission shaft 1 by support 2.The left end of transmission shaft 1 stretches out the left side of windmill housing, and is bearing on the bearing box 17 by bearing, and this bearing box 17 fixes with substrate 18, and substrate 18 is fixed on the left frame 4.Described motor 6 is fixedly mounted on the substrate 18, and the output shaft of motor 6 passes substrate 18 to the right, passes to be set with first gear, 7, the first gears 7 on the part and to be meshed with second gear 8 on the transmission shaft 1.
As can be known from Fig. 1, the right-hand member of transmission shaft 1 stretches out the right side of windmill housing, and transmission shaft 1 is bearing on the bearing box 19 by bearing near the position of right part, and this bearing box 19 is fixedlyed connected with the bottom of cantilever 12, and the top of cantilever 12 is welded on the right frame 5.Described rotating disk 10 is positioned at the right side of right frame 5, and this rotating disk 10 is the disk-like structure that has internal tooth, and the 3rd gear 9 engagements of the internal tooth of rotating disk 10 and transmission shaft 1 right-hand member suit.The middle part of rotating disk 10 is bearing in the right-hand member of little axle 11 by bearing, and little axle 11 is positioned at the top of transmission shaft 1, and left end of this little axle 11 passes the bar hole 13 on the cantilever 12, by nut 14 lockings.Be provided with journal stirrup 15 at the edge of described rotating disk 10, handle 16 is installed on this journal stirrup 15, handle 16 is perpendicular with rotating disk 10.
