Abstract
The utility model discloses a double-speed changing box of a rotary cultivator, which comprises a box body, wherein an input shaft, a shaft I, a shaft II, a shaft III, a shaft IV and an output shaft are sequentially connected with the box body in a transmission order; the input shaft is fixedly provided with a main bevel gear; the shaft I is provided with a duplicate slippage gear and fixedly provided with an auxiliary bevel gear engaged with the main bevel gear; the shaft II is fixedly provided with a high speed gear and a low speed gear that are engaged with the duplicate slippage gear; the shaft III is provided with a first free gear engaged with the low speed gear; the shaft IV is provided with a second free gear engaged with the first free gear; the output shaft is fixedly provided with the output gear engaged with the second free gear; and the duplicate slippage gear is driven by a shifting fork mechanism connected with the box body. The speed changing box has a simple and compact structure, can output at both high and low speeds, and can be directly connected with a rear power output shaft of an agricultural machine such as a tractor.
Description
Technical field
The utility model relates to gearbox, is specifically related to a kind of rotovator double-velocity transmission.
Background technology
Existing rotovator generally only is used for the soil rotary tillage, so that soil is become flexible.At present, by existing rotovator is improved, promptly change cutter shaft and blade after, can be used for crop is earthed up.During ridging, need the rotovator high speed rotating to break up the clods, to obtain fine earth; If the rotovator rotating speed is low, then soil block is bigger, injures by a crashing object easily or smashes rice shoot.The gearbox of existing rotovator has two kinds: a kind of single rotating speed and low speed output type, can only satisfy the rotary tillage requirement, and can't satisfy the instructions for use of ridging; Another kind is the double speed output type, though can realize the output of high low speed, the gearbox of this structure, all gear shafts all be arranged in parallel, can only be connected by the side power take-off of agricultural machinery such as driving-chain and tractor, make to connect more complicated.
Summary of the invention
The technical problems to be solved in the utility model is at above-mentioned defective, and a kind of high, low speed output of both having had is provided, the rotovator double-velocity transmission that the rear power output shaft of agricultural machinery such as convenient again and tractor is connected.
For solving the problems of the technologies described above, the utility model provides a kind of rotovator double-velocity transmission of following structure, comprises casing, and its design feature is: be connected with power shaft, I axle, II axle, III axle, IV axle and output shaft in turn by the transmission order on the described casing; Be fixed with master bevel gear on the power shaft, double crosslinking sliding gear is housed on the I axle and is fixed with the secondary bevel gear that meshes with master bevel gear, be fixed with on the II axle can with the high gear and the low-speed gear of double crosslinking sliding gear engagement, the first free gear with the low-speed gear engagement is housed on the III axle, the second free gear with the first free gears engaged is housed on the IV axle, is fixed with output gear on the output shaft with the second free gears engaged; Double crosslinking sliding gear is driven by the shifting fork mechanism that is connected on the casing.
Described shifting fork mechanism comprises the declutch shift shaft that is connected on the casing and is slidingly connected on the declutch shift shaft and fork is contained in shift fork on the double crosslinking sliding gear.
The gearbox of said structure when double crosslinking sliding gear and high gear engagement, can be realized output at a high speed, when double crosslinking sliding gear and low-speed gear engagement, can realize low speed output.Power shaft carries out power transmission with the I axle by the bevel-gear sett that is meshed, that is to say, power shaft and I axle are the arrangement relation of vertical interlaced, and what make power shaft and agricultural machinery such as tractor becomes very easy being connected of rear power output shaft, can carry out direct-connected.
In sum, the utlity model has simple and compact for structurely, the output of high low speed double speed can be carried out direct-connected advantageous effect with the rear power output shaft of agricultural machinery such as tractor.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cutaway view along A-A line among Fig. 1;
Fig. 3 is the cutaway view along B-B line among Fig. 1.
Embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the rotovator double-velocity transmission comprises casing 15, is connected with power shaft 1, I axle 2, II axle 3, III axle 4, IV axle 5 and output shaft 6 in turn by the transmission order on the casing 15; Be fixed with master bevel gear 7 on the power shaft 1, double crosslinking sliding gear 9 is housed on the I axle 2 and is fixed with the secondary bevel gear 8 that meshes with master bevel gear 7, be fixed with on the II axle 3 can with the high gear 10 and the low-speed gear 11 of double crosslinking sliding gear 9 engagement, the first free gear 12 with low-speed gear 11 engagements is housed on the III axle 4, the second free gear 13 that meshes with the first free gear 12 is housed on the IV axle 5, is fixed with output gear 14 on the output shaft 6 with second free gear 13 engagements; Double crosslinking sliding gear 9 is driven by the shifting fork mechanism that is connected on the casing 15.Shifting fork mechanism comprises the declutch shift shaft that is connected on the casing 15 16 and is slidingly connected on the declutch shift shaft 16 and fork is contained in shift fork 17 on the double crosslinking sliding gear 9.
The implication of free gear described in the utility model is freely to rotate around its assembled shaft, the implication of described shifting slide gear be can along its assembled shaft slide and with the dynamic annexation of its assembled shaft.
The utlity model has high low speed two speed outputs, its drive path following (Arabic numerals are the gear numbering in the accompanying drawing):
Low speed: 7 → 8 → 9 → 11 → 12 → 13 → 14;
At a high speed: 7 → 8 → 9 → 10 11 → 12 → 13 → 14.
