Description
Technical field
The present invention relates to a kind of fertilizer distributor, belong to agricultural machinery technological field.
Background technology
In order to obtain best economic benefit; and protection of the environment; guarantee agricultural sustainable development; meticulous fertilizer practice can be according to the profit and loss situation of various nutrients in different regions, soil type, soil, crop classification and yield level; by nitrogen, phosphorus, potassium and multiple trace element and the fertilizer scientific formula in addition that promotes plant growth; accomplish on purpose to apply fertilizers scientifically; so both reduce environmental pollution and agricultural product quality decline that excessive fertilization causes, played again the effect of saving synergy.
China's Rural Land Circulation is universal gradually at present, soil planting scale is increasing, the labour that is simultaneously engaged in agricultural production is fewer and feweri, and existing fertilizer distributor exists the problem of function singleness, bad adaptability, can not meet current precision agriculture fertilising demand.
Existing fertilizer applicator mostly is spinning fertilizer, and this is also that European and American countries is used to such an extent that the most general one is spread fertilizer over the fields facility, and it is to utilize centrifugal force that chemical fertilizer is spread out by the broadcast application dish of power output shaft driven rotary. But the chemical fertilizer under spinning fertilizer spreads in an operation is longitudinally very inhomogeneous with horizontal distribution, need to carry out many times operations; Existing spinning fertilizer can not be adjusted dose size in real time in addition. Ye You producer adopts spiral fertilizer distributor, but spiral fertilizer distributor can not be adjusted dose size equally in real time. Therefore, develop a kind of fertilizer applicator that can accurately apply fertilizer simple in structure, lower-cost and become problem demanding prompt solution.
Summary of the invention
The technical problem to be solved in the present invention is: propose a kind of fertilizer applicator that can adjust at any time dose size and reach according to agriculture requirement Tree Precise Fertilization.
The present invention is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of self-propelled multifunctional fertilizer applicator, described fertilizer applicator is located on tractor, comprise the receptacle being arranged on tractor, spiral widespread device and buncher, described spiral widespread device drives by the power takeoff being arranged on tractor gear case, described receptacle bottom is provided with discharging opening, described discharging opening place is provided with the fertilizer sheave being driven by buncher, described buncher starts storage battery by tractor powers, the below that is centered close to fertilizer sheave of described spiral widespread device; Described spiral widespread device comprises rotating shaft and be fixed on two groups of spiral blades on rotating shaft, and described two groups of blades are symmetrical centered by the middle part of rotating shaft, and the external diameter of described blade increases gradually from middle part to the two ends of rotating shaft.
The beneficial effect that the present invention brings is: the present invention adjusts the size of dose by the rotating speed of buncher control fertilizer sheave, can adapt to different fertilisings of planting fertilizer. The invention to start storage battery by tractor be buncher power supply, simplified the structure of this practical fertilizer applicator, reduced production cost. In addition, the present invention arranges fertilizer sheave by the discharging opening place at receptacle, can effectively prevent that fertilizer from stopping up at discharging opening place, and spiral widespread device is set below discharging opening, utilize more even that spiral widespread device can one-stop operation can spread fertilizer.
More even for what fertilizer was spread, realize Tree Precise Fertilization, the present invention can do following improvement:
1) pitch of described blade is divided into two kinds of pitch by size, and these two kinds of pitch distribute along the axially spaced-apart of rotating shaft.
2) pitch of described blade is dwindled gradually from center to the two ends of rotating shaft. In use, fertilizer is carried to rotating shaft terminal from discharging opening, the corresponding minimizing of amount of fertilizer, and it is more even that the pitch that reduces blade also can make that fertilizer spreads.
As preferred version, between the output shaft of described power takeoff and the power shaft of spiral widespread device, be provided with sprocket wheel, described power takeoff is by the spiral widespread device of this chain wheel drive. The power that can make full use of like this tractor, makes more compact structure of the present invention.
In order to prevent that discharging opening from stopping up, described discharging opening place is provided with the anti-blocking hairbrush matching with fertilizer sheave.
Brief description of the drawings
Below in conjunction with accompanying drawing, the invention will be further described.

Detailed description of the invention
Embodiment
As shown in Figure 1, the self-propelled multifunctional fertilizer applicator of the present embodiment, this fertilizer applicator is located on tractor, comprise the receptacle 1 being arranged on tractor, the spiral widespread device 5 and the buncher (not shown) that drive by the power takeoff 6 being arranged on tractor gear case, receptacle 1 bottom is provided with discharging opening, discharging opening place is provided with the fertilizer sheave 2 being driven by buncher, buncher starts storage battery by tractor powers, the below that is centered close to fertilizer sheave 2 of spiral widespread device 5. Fertilizer sheave belongs to prior art, and the fertilizer sheave 2 in the present embodiment adopts fertilizer sheave as shown in Figures 2 and 3.
As shown in Figure 4, spiral widespread device comprises rotating shaft 3-2 and is fixed on the upper also spiral blade 3-1 of rotating shaft 3-2, blade 3-1 is symmetrical distribution centered by the middle part of rotating shaft 3-2, and the external diameter of blade 3-1 increases to two ends gradually from rotating shaft 3-2 center. In use, fertilizer is carried from discharging opening to rotating shaft 3-2 two ends, the corresponding minimizing of amount of fertilizer, and it is more even that the external diameter that therefore increases gradually blade 3-1 can make that fertilizer spreads
In the present embodiment, between the output shaft of power takeoff 6 and the power shaft of spiral widespread device, be provided with sprocket wheel, power takeoff 6 is by the spiral widespread device 5 of this chain wheel drive. The power that can make full use of like this tractor, makes more compact structure of the present invention.
More even for what fertilizer was spread, realize Tree Precise Fertilization, the present embodiment can be done following improvement: 1) pitch of blade 3-1 is dwindled to two ends gradually from rotating shaft 3-2 center. In use, reduce at the amount of fertilizer mind-set two ends from rotating shaft, and therefore the pitch of blade 3-1 is dwindled gradually from rotating shaft 3-2 center is corresponding to two ends, can save the material of blade, improves motive operating efficiency simultaneously.
2) pitch of blade 3-1 is divided into two kinds of pitch by size, and these two kinds of pitch distribute along the axially spaced-apart of rotating shaft 3-2. It is more even that pitch spaced apart like this can make that fertilizer spreads.
In order to prevent that discharging opening from stopping up, the present embodiment can arrange at discharging opening place the anti-blocking hairbrush (not shown) matching with fertilizer sheave 2.
The present invention is not limited to the various embodiments described above, and all employings are equal to replaces the technical scheme forming, and all drops on the protection domain of requirement of the present invention.
