Description
One, technical field
The utility model relates to a kind of farm implements of sowing usefulness, specifically is the wheat small plot experiment precision sower of wheat scientific research and seminal propagation special use.
Two, background technology
At present, the wheat seeder that is used on the Wheat Production has two types, first kind is the gear sead feeder, modified for traditional sower, it only is the improvement on the manufacture craft, operation principle and flow process there is no improvement, still are compositions such as land wheel, seed-box, feed up, seeding gear, grain tube, plough, covering device.Mainly regulate seeding quantity, make seeding quantity little to 2.5kg/667m by regulating the length of seeding gear in feed up
2, but its shortcoming still exists, and the one, seeding quantity can only be little of 2.5kg, reduces its Seeding Uniformity again and descend; The 2nd, its seeding quantity needs repetition test, can not quick and precisely finish; The 3rd, sowing length can not artificially be controlled, and is continuous sowing type, can not adapt to the sub-district sowing in the scientific research.Second kind is the air-sucking type planter, this machine is made of parts such as blower fan, vacuum tube, sucker, seed-box, discharging tube, ploughs, it is a kind of novel single seed drill, seeder can be regulated by changing sucker, general wheat cultivation amount is 0.5～1kg, be suitable for light seeding breeding usefulness, the shortcoming one of this machine is that the amount of the broadcasting amplitude of accommodation is little, and it is rare numerous only to be fit to program request; The 2nd, it sows length, changes kind inconvenience, is not suitable for the needs of scientific research Precision Seeding.Domestic existing research and production have the 6 row wheat sub-district Precision Seeding machines supporting with tractor with small four wheels, and its volume is big, can only broadcast Da Qu, can not broadcast the sub-district, and inconvenience is operated in the field, is not suitable for the needs of wheat research work.External wheat plant planter also is 6 row special machines, the automaticity height, but cost an arm and a leg the impotentia configuration still of general R﹠D institution.Therefore, vast agri-scientific research unit presses for a kind of wheat small plot experiment precision sower of suitable China's national situation.
Three, utility model content
The purpose of this utility model is exactly to grind a middle seeding technique difficult problem that exists for solving present domestic wheat breeding and cultivated species, and provide a kind of efficient, easy, accurate, convenient, practical wheat small plot experiment precision drilling machinery, it is highly suitable for each agri-scientific research institutes, is particularly suitable for the wheat small plot experiment precision drilling of R﹠D institution of basic unit.
The purpose of this utility model can be finished in the following manner: the utility model is to be made of frame, transmission system, feed system, sub-material system, sowing system five parts, described frame is a rectangle, front and back are two handrail-type, preceding handrail to the frame between the back bar is arranged with ground wheel assembly, speed-changing chain assembly, support roller assembly, constitutes transmission system by above-mentioned three assemblies; Be provided with feed system with the corresponding frame of support roller assembly, described feed system is made up of big cone pulley, terminal pad, distributing device, material distributing cone, lucite tube, feeding hopper; Have under the frame and the corresponding sub-material of feed system system, described sub-material system is made up of direct current generator, tripper, distributing device, positioning disk, receiver; With the sub-material system is corresponding grain tube arranged, plough is formed the sowing system, and described sowing system is made of three grain tubes and three ploughs.
The utility model has following good effect compared with the prior art:
The first, owing to take said method, can satisfy the requirement of following wheat scientific research sowing:
1, the adjusting of the amount of broadcasting: traditional method is with the method adjustment amount of broadcasting of adjusting sowing gear length in feed up, and is difficult for quantitatively.The utility model adopts material separating disc, pours the seed that weighs up into the feeding cup, through twice sub-material, be evenly distributed on the material separating disc, the amount of broadcasting is with to broadcast speed irrelevant, only synchronous with sowing length, and realize the purpose what add, what are broadcast, satisfied requirement changeable in the scientific research to the amount of broadcasting.According to design performance, broadcast weight range at 1～10kg/667m
2Between, can satisfy the needs of wheat research work.
2, the sowing length: the regulation length with sower in seed finish, the utility model makes branch kind dish broadcast long inward turning in regulation by a rotating speed of regulating branch kind of dish and turns around, with seed row down, regulate by main driven gear, realized that 2 * 5=10 is broadcast long the adjusting, broadcast long scope 2～20m, satisfied the requirement of different tests sub-district sowing.
3, seed cleaning: the utility model adopts that material separating disc evenly divides kind, seeding, and without seed cup in the conventional method and seeding gear, and seed is broadcast length in regulation, material separating disc rotates a circle, and seed is all arranged down, and material separating disc is uncovered, do not hide, card type, having realized the anti-assorted pure requirement of protecting.
4, line-spacing adjustment: the utility model is a triplex row Precision Seeding machine, and three ploughs can carry out the line-spacing adjustment, and adjusting range is 10～30cm, can satisfy the different condition needs.
5, machine weight and specification: the utility model complete machine weight 25kg, main frame length * wide * height is 2000 * 800 * 1000mm, be fit to manual operation, 1 people's handle, 2 people pulling, 1 people helps, and 4 people can operate, the field turns to very convenient, is fit to the needs of various wheat cultivations such as wheat breeding field, seminal propagation field, small plot experiment field.Also be applicable to simultaneously requirement of seeding such as corn, soybean,, also can broadcast small-sized seed such as vegetables, millet, sesame etc., have practicality very widely as changing feeding cup and tripper.
6, operating efficiency: wheat scientific research material field sowing 0.2hm
2/ h, sub-district sowing 0.4hm
2/ h, breeding field sowing 0.5hm
2/ h.Operating efficiency is 10 times of conventional method, and seeding quality obviously improves.
The second, the easy manual operation of the utility model, volume is little, in light weight, and price is low, can solve the problem of basic agriculture research unit expenditure allowance anxiety preferably, has application value widely.
