Technical field the utility model relates to the conservation tillage mechanical field of agricultural machinery medium drought resistant water saving.
Background technology is in the vast northern dry farming district lack of water short of rain of China, and spring is arid especially.Too poor because of soil moisture content during the spring sowing operation, moisture content is extremely low, and seed is difficult to germination and emergence.For ensureing emergence rate, the agronomy that local peasant always has the pouring of carrying water to sow, common name bed-irrigating sowing.But manual type not only uses the labour many, and labour intensity is big, and operating efficiency is low, and can not give full play to the water effect, wastes water source in short supply.Since nineteen nineties, China various places have been developed the Watering sower of supporting middle-size and small-size tractor successively, progressively promote the mechanization bed-irrigating sowing.But the basic structure of existing Watering sower all is that storage tank is erected on the tractor, and sower then hangs or be pulled in rear tractor, and storage tank is communicated with structural separation with executing between the hydrophone of sower with delivery hose.Its shortcoming is: 1, the user is not easy to reequip tractor and sets up storage tank and restore with the dismounting after finishing; 2, storage tank blocks tractor driver's sight line, it is had tunnel vision and influences job safety; 3, be subjected to the restriction of tractor vertical, horizontal stability and rear wheel bearing power, the storage tank volume is less, and the moisturizing number of times is more in the operation, has reduced operating efficiency; 4, the gravity that can't utilize storage tank and carry water applies the plough of sower and is beneficial to the pressure of cutting stalk, breaking and burying, thereby is difficult to the tillage free or reducing bed-irrigating sowing that competent stalk covers stubble-field.
The summary of the invention the purpose of this utility model is to overcome the deficiencies in the prior art, designs a kind of fertilising that storage tank and combined seed and fertilizer drill are combined closely into configuration and sits the water drilling machine, articulates with tractor one of in a usual manner.
The purpose of this utility model reaches by following design: the water drilling machine is sat in a kind of semimounted tillage free or reducing fertilising, it is characterized in that shaped as frame frame front top installation fertilizer seed storage arranging device, and storage tank is installed in the postmedian top; The hinged side by side a plurality of stalk breaking ploughs of cutting of lower front, each compartment upper limb of cutting stalk breaking plough is communicated with the water conduction hose of leading fertile flexible pipe, leading kind of flexible pipe and storage tank of fertilizer seed storage arranging device respectively, and its lower edge is respectively the outlet of fertilizer, water and seed; A land wheel is respectively installed in shaped as frame central rack both sides, the sprocket wheel coaxial with it respectively with the fertilizer expelling shaft sprocket wheel of fertilizer seed storage arranging device both sides and feed shaft sprocket wheel with chain drive; Suppressing wheel device is installed in shaped as frame central rack below, and lower rear is installed thrust wheel device; The hinged frame that pulls round of shaped as frame frame front end; The plough lifting device with pull round frame, shaped as frame frame and cut stalk breaking plough rear portion respectively hinged; Described each main parts size is formed the machinery of compact conformation, tool configuration and multinomial function.Front end pulls round frame and 3 of wheel tractor rear portion hydraulic lift hitch articulate, and the rear portion supporting wheel lands all the time, the part weight of supporting machinery.The routine that this half hang is tractor and outfitting tool articulates one of mode, and the user hangs and unloads conveniently.On tractor, do not set up storage tank and need not reequip tractor; the tractor driver is not limited in the visual field; it is more and can improve operating efficiency that the storage tank volume carries water more greatly; and the part gravity that can utilize storage tank and year water thereof applies plough and is beneficial to the pressure of cutting stalk, breaking and burying; thereby competent stalk covers the no-tillage ground of toothing or minimal tills the fertilising bed-irrigating sowing on ground, adapts to the demand of the conservation tillage mechanization of resisting drought saving water.
Below in conjunction with accompanying drawing the utility model is further described.
Appended drawings has been expressed one of embodiment of the present utility model---the structure that the water drilling machine is sat in the seven row fertilisings of semimounted tillage free or reducing.Fig. 1 is the schematic diagram of its farm work state, and Fig. 2 is the vertical view corresponding to Fig. 1, and Fig. 3 is its headland turn or the schematic diagram that shifts transport condition.
Embodiment semimounted tillage free or reducing seven row fertilisings is as depicted in figs. 1 and 2 sat the water drilling machine, and its fertilizer seed storage arranging device 3 is installed on the front upper of shaped as frame frame 1, and storage tank 9 is installed on the postmedian top of shaped as frame frame; Cutting stalk breaking plough 2 front ends for seven is articulated on the anterior crossbeam of shaped as frame frame, its spacing can be adjusted as required, each upper limb of cutting the compartment of stalk breaking plough is communicated with the water conduction hose 5 of leading fertile flexible pipe 4, leading kind of flexible pipe 8 and storage tank of fertilizer seed storage arranging device respectively, and its lower edge is respectively the outlet of fertilizer, water and seed; Two land wheels 12 are installed on the shaped as frame frame left-right longeron outside respectively, with the coaxial sprocket wheel 15 of land wheel respectively with the fertilizer expelling shaft sprocket wheel 16 of fertilizer seed storage arranging device both sides and feed shaft sprocket wheel 6 with chain 7 transmissions; Suppressing wheel device 11 is installed on the postmedian below of shaped as frame frame; The wheel shaft of thrust wheel device 10 is fixed tightly in shaped as frame frame lower rear, and a pair of wheel of axle head is positioned at the outside about frame; Pull round frame 13 and be articulated in the front end of shaped as frame frame; To cut stalk breaking plough rear portion hinged with pulling round frame, shaped as frame frame and seven respectively for 14 of plough lifting devices.Above-mentioned main parts size is formed the machinery of compact conformation, tool configuration and multinomial function.Front end pulls round frame and 3 of wheel tractor rear portion hydraulic lift hitch articulate, and the rear portion supporting wheel lands all the time, the part weight of supporting machinery.This half hang articulates one of mode as the routine of tractor and outfitting tool and the user is hung unload conveniently.During the unit farm work, for drilling crops such as wheat class, millet no-tillage ground minimal till ground or ploughed on once stroke can finish cut stalk, breaking, trench digging, apply fertilizer, pour water, multiple working procedures such as sowing, earthing, suppression.As shown in Figure 1, the machinery front end descends, floats and be pulled and advance with the tractor hydraulic suspension arrangement, because reasonably center of gravity configuration, storage tank and the gravity that carries water thereof have considerable part to put on to cut on stalk breaking plough and the land wheel, make the plough enough pressure of acquisition and cut off stalk smoothly, abolish the root stubble and limit deep ditching to loosen the soil according to land wheel; Land wheel rotate to drive fertilizer seed storage arranging device running and down fertilizer sow, the storage tank draining, fertilizer, water, kind import the compartment of plough respectively through flexible pipe, through the lower edge outlet in lines layering apply in the ditch; Through the spreading of the earthing and the suppressing wheel device of plough trailing edge, finishing the multiple operation that water drilling multiple working procedure is sat in fertilising again.Because storage tank size, weight are restricted few, its volume is bigger, and it is more to carry water, thereby can reduce the edge of a field moisturizing frequency, improves operating efficiency; Its weight also helps machinery and covers the no-tillage ground of toothing or minimal till operation smoothly on the ground at stalk.At headland turn with shift transport condition as shown in Figure 3; the machinery front end is stowed the machine hydraulic lift hitch and promotes and draw; cut stalk breaking plough is unearthed thereupon; land wheel is liftoff; the fertilising seeding operation of pouring water stops automatically; thrust wheel device lands and bears most of weight of machinery; also because the interlock that the plough lifting device promotes with the tractor hydraulic suspension arrangement; to cut stalk breaking plough rear portion further promotes; make and cut stalk breaking plough lower edge enough terrain clearances are arranged, ensure safety and turn and travel.
