Abstract
The utility model provides a reverse speed change gear box connected between a hand tractor and a rotavator, comprising a reverse speed change gear box 5, a transmission shaft 6 of the reverse speed change gear box, a power input normally engaged gear 7, and an output normally engaged gear pinion (11). The device is used together with the hand rotavator so that the prior rotavator realizes reversion and has the high and low variable rotating speed output to realize field operations such as reversing stubble ploughing and reversing straw breaking land return. The device has a compact structure and reliable transmission and is an ideal assorted machine for strictly prohibiting the straw burning and promoting the straw breaking land return.
Description
Affiliated technical field
The utility model relates to a kind of farm machinery, especially a kind of coupling arrangement that is used for connecting between hand tractor and the rotary cultivator farm works such as can realizing the sowing of derotation stubble-cleaning, derotation straw chopping and returning.
Background technique
Along with wideling popularize, country forbid crop straw burning, the cultivation practice of promotion straw chopping and returning, the rotary cultivator of the various lots of walking tractor matching in rural area to press for solution counter-rotating stubble-cleaning and the operation of counter-rotating straw chopping and returning.The type of at present domestic some newly-designed special-purpose counter-rotating rotary tillage stubble-cleaning and derotation crushed stalk, not general because the uni-drive gear box of rotary cultivator is a special designs, the cost height, the popularization amount is few.Design a kind of connection gear box that can connect the speed change that to realize reversing, great popularization market will be arranged with the huge hand steered supporting rotary cultivator of owning amount.
Summary of the invention
The purpose of this utility model is to provide a kind of can the connection with the rotary cultivator of walking tractor matching can realize derotation, and two kinds of operation rotating speeds can be provided, and realizes that the novel trans of sowing of low speed derotation stubble-cleaning and the operation of high speed derotation straw chopping and returning changes fast gear-box.
Technical solution of the present utility model is: increase a connection gear box between former hand tractor and rotary cultivator, a transmission shaft is only arranged in this gear-box, so make the former rotary cultivator that just changeing realize the counter-rotating operation.Having the gear that varies in size on transmission shaft can select engagement to realize different counter-rotating operation rotating speeds for rotary cultivator.A gear (25-28 tooth) is meshed with 24 gears on the hand tractor output shaft on the transmission shaft, power is reached transmission shaft again by different gears on the transmission shaft and rotary cultivator input gear engagement, thereby obtain different counter-rotating rotary tillage rotating speeds, adapt to the requirement of different derotation agronomy operation.
Description of drawings
The schematic representation that Fig. 1 connects with hand tractor and supporting rotary cultivator (two chain line part) for the utility model counter-rotating speed-change gear box (heavy line part).
In the drawings, 1, hand tractor output shaft 2,17 gears 3,24 gears 4,30 gears 5, counter-rotating speed change gear casing 6, counter-rotating speed-change gear box transmission shaft 7, with input power constant mesh gear 8, rotary cultivator power input shaft 9, slip clutch gear 10, often mesh clutch gear 11, export normal pinion mate.
Embodiment
In Fig. 1, in the counter-rotating speed-change gear box 5 transmission shaft 6 is only arranged in the utility model counter-rotating speed-change gear box, on the axle two speed change gears are housed, wherein import power constant mesh gear (7) and the normal engagement of hand tractor power output gear (3), by counter-rotating speed-change gear box transmission shaft (6) power is reached normal pinion mate (11), rotary cultivator often meshes clutch gear (10) and the normal engagement of the normal pinion mate of output (11), because unpowered drive splines in the normal engagement clutch gear (10), so only go up idle running at rotary cultivator power input shaft (8), transfer motion power not, when slip clutch gear (9) is meshing with each other with the tooth embedding of normal engagement clutch gear (10), power reaches gear (9) by the tooth embedding and by slip clutch gear (9) internal spline power is reached rotary cultivator power input shaft (8) again, is the counter-rotating slow-speed of revolution this moment.When slip clutch gear (9) slides on the spline of rotary cultivator power input shaft (8) and constant mesh gear (7) when engagement, rotary cultivator power input shaft (8) the high rotating speed that must reverse.Slip clutch gear (9) is counter-rotating speed-change gear box auxiliary equipment.
Claims (3)
1, a kind of counter-rotating speed-change gear box of and walking tractor matching, by counter-rotating speed change gear casing (5), counter-rotating speed-change gear box transmission shaft (6), input power constant mesh gear (7), export normal pinion mate (11) and form, it is characterized in that: only have in the counter-rotating speed-change gear box (5) on a transmission shaft (6), the axle two speed change gears are housed, wherein import power constant mesh gear (7) and the normal engagement of the power output gear (3) of 24 teeth of hand tractor, export normal pinion mate (11) and often mesh the normal engagement of clutch gear (10) with rotary cultivator.
2, the counter-rotating speed-change gear box of described a kind of and walking tractor matching of claim 1 is characterized in that importing power constant mesh gear (7), and the number of teeth is the 25-28 tooth.
3, the counter-rotating speed-change gear box of described a kind of and walking tractor matching of claim 1, it is characterized in that rotary cultivator slip clutch gear (9) can with the structure of input power constant mesh gear (7) engagement.
