Abstract
The utility model relates to a rotary cultivator for matching with a walking tractor. A coulter speed-changing box is connected with a coulter driving box through a drive shaft of the coulter speed-changing box, the coulter driving box is connected with a coulter shaft in a driving mode and a bent coulter is arranged on the coulter shaft. The utility model is characterized in that an inner-engaging type speed-changing gear is arranged in the coulter driving box to realize two types of speed change; the coulter adopts a double-hole and double-bolt structure to be fixed on a clamp seat for the coulter shaft. The utility model has the advantages of simple structure, favorable performance and high productive efficiency and is especially suitable for cultivating irrigated land or dry land and leveling soil.
Description
The utility model relates to a kind of rotovator that hand tractor uses that is matched in.
Existing rotovator does not have shifting apparatus, and function singleness can not be carried out variable speed operation according to job requirement during operation.The colter fixed form is unreasonable on the rotovator simultaneously, and is often loosening in the use, causes distortion, and rotary tillage efficient is low; Colter is arranged also unreasonable, and colter quantity is on the low side, and the colter relative spacing is bigger, the rotary tillage weak effect.
The purpose of this utility model is to overcome the defective that prior art exists, but a kind of shift is provided, simultaneously the rational rotovator of colter fixed form.
The scheme that the utility model purpose realizes is that the rotovator that is provided is to be connected with the colter transmission case by its power transmission shaft by the colter gearbox, is connected transmission by the colter transmission case with coulter shaft again, and curved colter is housed on the coulter shaft, wherein:
The colter gearbox is made up of declutch shift shaft, the quick gear of colter, shift fork, driving lever, colter low-gear, bearing and power transmission shaft, driving lever is contained in the circular hole on the gearbox, the driving lever lower end is injected in the driving lever groove of shift fork, shift fork is contained on the declutch shift shaft, the declutch shift shaft two ends are supported by gearbox, power transmission shaft is equipped with quick gear and low-gear, and the axle of gear both sides has bearing to support, and the prong of shift fork injects in the fork slot of low-gear; Or/and curved colter is with two being bolted on the colter holder on the coulter shaft side by side.
The utility model rotovator is exported in the colter gearbox by hand tractor gearbox power, through the broken clod of the curved colter speed change rotatory force of transmission utilization, realizes the rotary tillage and the high-efficiency homework of leveling land.Because quick gear and low-gear are housed, make that this rotovator can be realized soon, shift rotary tillage operation slowly in the colter gearbox; Simultaneously, adopt the change-speed gearing of inner gearing type to realize speed changing function, do not increase the volume of gearbox; Colter adopts the two bolt arrangements of diplopore to be connected and fixed, and it is often loosening to solve colter effectively, causes the colter distortion and the shortcoming of rotary tillage weak effect.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the utility model rotovator cross-sectional view.
Fig. 2 is Figure 1A-A cut-away view.
As shown in the figure: left support arm 1 is connected and fixed with four bolts 2 of left arm housing 3 usefulness, and the left side of left arm housing 3 the right and colter gearbox 5 is fixing with four bolts 4; Colter gearbox 5 the right and four bolts of right arm housing 14 usefulness 12 are fixing, and right arm housing 14 the right and four bolts of colter transmission case 16 usefulness 18 are fixing.The inside of colter gearbox 5 is made up of declutch shift shaft 6, the quick gear 7 of colter, shift fork 9, driving lever 8, colter low-gear 10, two bearings 11, power transmission shaft 13 etc., driving lever 8 is contained in the circular hole on the gearbox 5, inject in the driving lever groove of shift fork 9 below the driving lever 8, shift fork 9 is contained on the declutch shift shaft 6, and declutch shift shaft 6 two ends are supported by gearbox 5; Quick gear 7 and low-gear 10 are equipped with in power transmission shaft 13 left sides, the gear both sides have bearing 11 to support, the prong of shift fork 9 injects in the fork slot of low-gear 10, power transmission shaft 13 right-hand members put in the colter transmission case 16 by right arm housing 14 and bearing 15 from the right of colter gearbox 5, power transmission shaft 13 right-hand members are rectangular splines and are connected with minor sprocket 17, through duplex chain 19, be connected to hinge wheel 20 and be connected with large size coulter shaft 21 right-hand member rectangular splines.Large size coulter shaft 21 is weldingly fixed on the colter central siphon 25, and colter holder 26 is weldingly fixed on the colter central siphon 25.Curved colter 27 adopts the two bolt arrangements of diplopores to be connected and fixed, and 24 respectively are fixed on curved colter on the colter holder 26 of cross arrangement with two bolts 28 respectively.Large size coulter shaft right-hand member supports with bearing 22, and seal receptacle 24 sealing and dustproof waterproof are arranged, and four bolts 23 of seal receptacle 24 usefulness are connected colter transmission case 16 lower ends; Large size coulter shaft 21 left ends have left bearing 29 and left shaft holder 30 to support, and fix with two bolts 31 and left support arm 1, constitute the rotovator framework.
The transmission order is as follows:
One grade: the hand drawing force → gear 7 → low-gear 10 → power transmission shaft 13 → minor sprocket 17 → roller chain 19 → hinge wheel 20 → large size coulter shaft 21 realizes quick rotary tillage operation fast.
Second gear: hand drawing force → low-gear 10 → power transmission shaft 13 → minor sprocket 17 → roller chain 19 → hinge wheel 20 → large size coulter shaft 21 realizes rotary tillage operation at a slow speed.
