The stiff end of hydraulic cylinder is fixedly connected on the hand tractor body, other has oil pump to be fixedly mounted on the hand tractor body, be connected with oil pipe between oil pump and the hydraulic cylinder, the power intake of oil pump is in transmission connection by the output of belt pulley and hand tractor gearbox; Described cradling piece is fixedly connected on the handgrip of hand tractor by binding device.
After adopting technique scheme, this rotovator can be pulled on hand tractor easily and be used, and has satisfied that green house of vegetables etc. is short, the use of narrow occasion.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 2, the rotary cultivator attachment that is used for hand tractor described in the utility model comprises middle-mounted gear case 1, be fixedly connected on the left central siphon 2 and the right central siphon 3 of gear-box 1 left and right sides, the outside of left side central siphon 2 and right central siphon 3 is equipped with Left Drive case 4 and right transmission case 5 by bearing respectively, be provided with driving gear 11 in the gear-box 1, be separately installed with left driving shaft 21 and right driving axle 31 in left side central siphon 2 and the right central siphon 3, the inner of left driving shaft 21 and right driving axle 31 is connected with driving gear 11 respectively, the outer end of left driving shaft 21 and right driving axle 31 is fixedly connected with travelling gear 14 respectively, 15, this travelling gear lays respectively in Left Drive case 4 and the right transmission case 5, and respectively by idler gear and the terminal gear 12 that is arranged in Left Drive case 4 or right transmission case 5 equally, 13 are in transmission connection, terminal gear 12, connect rotary ploughing cutter shaft 18 on 13, on the rotary ploughing cutter shaft 18 rotary blade is installed.Said structure is the known technology in rotovator field, no longer is described in detail at this.
On left central siphon 2 or right central siphon 3, be set with slip ring 6, be installed with fork 61 and pressure pin 62 on the slip ring 6, fork 61 is hinged on the flexible end of hydraulic cylinder 7, and pressure pin 62 is fixedlyed connected with cross bar 8, fixedlys connected with right transmission case 5 with Left Drive case 4 respectively in the two ends of described cross bar 8; On left central siphon 2 and right central siphon 3, be fixedly connected with cradling piece 10 by fastener.
As shown in Figure 1, the stiff end of hydraulic cylinder 7 is fixedly connected on the hand tractor body, and other has oil pump 9 to be fixedly mounted on the hand tractor body.This hand tractor adopts horizontal hand tractor gearbox, has the engine installing rack at the front end of hand tractor gearbox, and mounting diesel engine 20 on the engine installing rack, the fixedly connected handgrip 11 in the upper end of hand tractor gearbox.Oil pump 9 can have multiple with the concrete installation site of hydraulic cylinder 7, for example can as shown in Figure 2 oil pump 9 be fixedly mounted on the upper end of hand tractor gearbox 19 by support, the stiff end of hydraulic cylinder 7 is connected to the side of hand tractor gearbox 19, certainly, also can be installed in other relatively-stationary positions of hand tractor body as required.Be connected with oil pipe between oil pump 9 and the hydraulic cylinder 7, thereby the hydraulic oil of oil pump 9 outputs be transported to the flexible end generation expanding-contracting action of hydraulic cylinder 7 promotion hydraulic cylinders 7 by oil pipe.The power intake of oil pump 9 is in transmission connection by the power take-off 92 of belt pulley 91 with the hand tractor gearbox, provides power by the hand tractor gearbox for oil pump 9.Certainly, have the control lever of controlling its duty on the oil pump 9, for the ease of operation, can be by on the handgrip that is operationally connected to hand tractor of pull bar with control lever, the structure of hydraulic cylinder 7 and oil pump 9 is a known technology, also no longer is described in detail at this; Described cradling piece 10 is fixedly connected on the handgrip 11 of hand tractor by binding device, plays the effect that connects support.
