Description

The dual-purpose sower of floods and droughts

The utility model relates to farm machinery, particularly the dual-purpose combined seed and fertilizer drill of floods and droughts.

At present, water, what the drought sower generally used is by hand tractor traction combined seed and fertilizer drill, one people starts hand tractor, the one man operation combined seed and fertilizer drill, adopt this equipment to sow not only complicated operation, the complete machine body is big and heavy, therefore very inapplicable, in order to address this problem, people have done multiple effort, as Chinese patent disclose for No. 90224215.6 a key name be called " corn drill " patent disclosure a kind ofly form by main frame and fertilizing and seeding apparatus mounted thereto, the driving wheel drive transmission device of tractor drives the feed shaft and the fertilizer expelling shaft of combined seed and fertilizer drill, seed wheel is housed on the feed shaft, have feed outlet on it, each feed outlet is equipped with plants plug clearly, three cams are equipped with in the gap on the fertilizer expelling shaft, and interacting to be fixed on cam on the axle has telescopic plunger assembly on the fertilizer casing, and this device can solve existing implanted device can not sow problems such as vernalization seed and efficient are low, the problem that exists is that purposes is single, and manufacturing cost is higher.

Task of the present utility model is: overcome the deficiencies in the prior art, design a kind of can fertilising, the dual-purpose farm machinery of multi-functional floods and droughts such as stubble-cleaning, level land, sowing, intertillage, ridging, suppression, spray medicine.

Task of the present utility model realizes as follows: the dual-purpose sower of floods and droughts has a rectangular shaped as frame frame, unsteady land wheel is equipped with by welding gripper shoe thereon in its rear end, both sides, be positioned on the rear cross beam of frame frame below tie ridger and soil distributing apparatus are installed, by gripper shoe press wheel is housed, seed-box is housed on the frame, the quantity of seed-box is three, rotating stubble-cleaning wheel is equipped with by fixed support plate in the front end left and right sides of frame, on the stubble-cleaning wheel blade is housed, be fixed on gear-box is arranged on the frame, the power shaft of gear-box links to each other with universal joint, universal joint is driven by tractor output shaft, be positioned at frame above the chemical fertilizer case is housed, the fertilising pipe that has at the chemical fertilizer case is broadcast moving axis by chemical fertilizer and is controlled its work, the output of gear-box drives chemical fertilizer by chain and broadcasts moving axis and transmission cutter shaft.

The utility model can be realized multinomial farmland operations such as fertilising, stubble-cleaning, level land, sowing, intertillage, ridging, suppression, spray medicine by one man operation, has improved operating efficiency widely, has reduced the labour, is the effective tool that improves farmland operation efficient; Adopt the comparable existing machine of this machinery operation to improve 3 times of speed, improve 20 times than manual work.

Fig. 1 is the utility model overview;

Fig. 2 is the lateral plan of Fig. 1;

Fig. 3 broadcasts the moving axis view for chemical fertilizer;

Fig. 4 is that the K of Fig. 1 is to view;

Fig. 5 is the cutter shaft view.

Most preferred embodiment of the present utility model, as figure, the universal joint 1 that is driven by tractor output shaft is bearing on the frame 6 by hitch frame, universal joint drives power transmission shaft 3 successively, gearbox 4, the output shaft of gearbox drives cutter shaft by adhesive tape, drive is housed on cutter shaft, this drive drives chemical fertilizer by chain drive and broadcasts moving axis 24 operation of applying fertilizer, the structure of broadcasting moving axis 24 as shown in Figure 2, its installation site is the bottom that is positioned at chemical fertilizer case 5, is fixed with columniform hollow cylinder on the power transmission shaft 24, has strip broadcast application hole at the surface and the axis parallel of hollow cylinder, fertilising pipe 14 is housed below the chemical fertilizer case, and its course of work is; The following bottom door of chemical fertilizer case is opened when drive drives its rotation by chain, along with the rotation fertilising pipe of broadcasting on the moving axis spreads chemical fertilizer to the farmland equably.Be positioned at above the frame rear portion seed-box 25 is housed, quantity is 3.The land wheel 15 of floating rotates along with the walking of tractor, driving sowing axle 23 by the chain gear transmission on it rotates, sowing axle 23 is positioned at going to the bottom of seed-box 25, on the sowing axle movable pulley 16, fixture sliding beam 18 are housed, its structure as shown in Figure 4, it is adjustable to have the horizontal planting hole spacing that makes of different rectangular ditches above the beam 18, overcoat 17 is housed outside seed-box, as shown in Figure 4, different feed outlets cooperated with movable pulley 16, sliding beam 18 about it had two respectively, then can adjust 6 kinds of different feed outlet spacings.

Be installed in the below that is positioned at frame on the rear cross beam of frame tie ridger 7 and soil distributing apparatus 19 are installed, on rear cross beam, press wheel 10 is installed by support 20.The device 22 of spraying pesticide can be housed on the rear cross beam of frame.Rotating stubble-cleaning wheel is equipped with by fixed support plate in the front end left and right sides in frame, and the stubble-cleaning wheel is gone up and by cutter shaft blade is housed.In the front lower place of frame the level land plate is housed, tie ridger is equipped with in the back lower place.The whole system operation process is: the power take-off of tractor is by universal joint uni-drive gear box 4, and the output shaft of gear-box is finished by sprocket wheel and chain belt movable arbor and chemical fertilizer sowing axle and broadcast chemical fertilizer and stubble-cleaning.

The walking of tractor drives land wheel rotation the carrying out level land work of floating, the land wheel that meanwhile floats drives the seeding wheel rotation by chain gear transmission and sows, when walking, finishes the tie ridger random device of the frame back lower place work of ridging, Seeding box, fertilizing box are opened and closed, and the level land plate that is positioned at the frame front lower place can be intertilled.
