Description
Technical field
The utility model relates to the dispenser that a kind of sower is used, particularly a kind of automatic seeding unit of air-sucking type that is used to sow various crop seeds.During this seeding unit operation, both can carry out single file sowing, also can on big ridge, carry out multi-row seeding, can not only be at a ridge upper seeding wheel, and can be simultaneously at the Duo Tiaolong upper seeding wheel.
Background technology
At present, along with the raising of agriculture cultivation technology and the accurately popularization of seeding technique, people are more and more higher to the requirement of agricultural seeder machinery.Existing sower kind is more, and promising large and middle tractor is supporting, and also promising small tractor is supporting, but used dispenser all forms integral structure with sower.Although the seeding accuracy of every kind of sower is all very high, yet its sowing function is very single, and the sower that promptly carries out the single file sowing can not carry out double row sowing or can not carry out multi-row seeding on big ridge; What have only can be at a ridge upper seeding wheel, and can not be simultaneously at Duo Tiaolong upper seeding wheel or the like, can not be general.In addition, kind of dish damage seed is easily scraped in existing air-sucking type sowing, and feed outlet is in a single day blocked, can influence the precision of sowing, increases the hole rate of seeding operation.The structure of two-layer cylinder air-sucking type seeding apparatus is complicated, has increased device fabrication cost and maintenance amount.Therefore, existing implanted device haves much room for improvement.
The utility model content
The purpose of this utility model provides the automatic seeding unit of a kind of air-sucking type, and its structure distribution is reasonable, and is simple to operate, easy to use, applied widely, seeding quantity is accurate, spacing in the rows, line-spacing unanimity, injuring-free seed during operation, hole not significantly improve seeding operation efficient and seeding quality.
The purpose of this utility model is achieved in that this device comprises and has seed chamber, hollow fixed axis on the housing of guide duct and the assemble case, seed wheel, its technical essential is: the seed wheel end of described circumference radial distribution suction hole is fixed with sprocket wheel, and utilize the bearing group in the wheel hub to be contained on the hollow fixed axis, the rotation of seed wheel by sprocket wheel drives it and rotates on hollow fixed axis, hollow fixed axis one end communicates with the seed wheel inner chamber, the other end utilizes pipe joint to be connected induced-draught fan with guide duct, spring is fixed on choke slider bottom curved surface on the hollow fixed axis and the inner arm curved surface of the seed wheel circumference radial distribution suction hole that contacts with it matches by adjusting, and the shielded area of choke slide block curved surface is greater than the area of the seed wheel suction hole that is blocked.
Because the utility model adopts negative-pressure adsorption principle, utilization is assembled in the absorption of the suction hole realization seed of the seed wheel on the hollow fixed axis and moves, to be placed on the wind regime of the choke slide block partition suction hole in the seed wheel, make seed break away from suction hole by deadweight, fall into predetermined kind cave exactly, so it is accurate to reach seeding quantity, the purpose of spacing in the rows, line-spacing unanimity.This device adopts pneumatic structure, and is simple to operate, easy to use.Because seed adsorbs automatically, cut off the wind regime of suction hole with built-in choke slide block, directly do not contact with seed during operation again, so structure distribution is reasonable, injuring-free seed, hole not significantly improve seeding operation efficient and seeding quality.The suction hole of its seed wheel can be according to actual needs, along single-row suction hole of circumference radial distribution or multiple row suction hole, so that carry out on the ridge single file sowing or carry out big ridge multi-row seeding.Can also be with a plurality of uses arranged side by side of this device so that at the Duo Tiaolong upper seeding wheel, therefore, the scope of application is wider.

Embodiment
Describe concrete structure of the present utility model in detail according to Fig. 1-4.The automatic seeding unit of this air-sucking type can be installed on any one sower that has induced-draught fan.It comprises the part such as housing 7, the hollow fixed axis 16 on the assemble case 7, seed wheel 12 of the guide duct 8 that has seed chamber 17, is connected with induced-draught fan.During installation, need only its housing 7 be connected the seeding of sower along getting final product between beam and the roller sealer support with fastening bolt.Wherein the specification of casing, model should be according to the actual crop that will sow (corn, soybean, Chinese sorghum, peanut etc.) kind, need the form (single file sowing, multi-row seeding, unit sowing or multimachine sowing) of sowing to select.Also can determine thus the specification of seed wheel 12 and suction hole size, quantity what, to adapt to different seeding operation requirements.The radially-arranged suction hole of seed wheel 12 circumference can have only a row feed outlet, also the multiple row feed outlet can be arranged, and when the multiple row feed outlet, each feed outlet that is listed as same row can stagger or row's arrangement together, makes it to adapt to the spacing in the rows of sowing, the needs of line-spacing.The end of seed wheel 12 is fixed with sprocket wheel 2, and this sprocket wheel is connected with the driving wheel 10 that power source drives by driving-chain 1.Seed wheel 12 utilizes the bearing 19 in the wheel hub 20 to be assembled on the hollow fixed axis 16.The rotation of seed wheel 12 by sprocket wheel 2 drives it and rotates on hollow fixed axis 16.Hollow fixed axis 16 1 ends communicate with the inner chamber of seed wheel 12, and the other end utilizes pipe joint 11 to be connected induced-draught fan with guide duct 8.Spring 15 is fixed on choke slide block 14 bottom curved surfaces on the hollow fixed axis 16 and the seed wheel 12 inner arm curved surfaces of the circumference radial distribution suction hole that contacts with it match by adjusting.The shielded area of choke slide block 14 curved surfaces is greater than the area of seed wheel 12 suction holes that blocked.During the sower operation, after induced-draught fan started, the inner chamber of seed wheel 12 promptly produced the negative-pressure adsorption effect, in seed wheel 12 rotation processes, at the radially-arranged suction hole of its circumference seed is adsorbed on periphery eyelet place by grain by pre-provisioning request, and along with the periphery of seed wheel 12 together moves.When the choke slide block 14 in being placed on seed wheel 12 cut off the wind regime of suction hole, the seed that is adsorbed had just lost suction, breaks away from suction hole by deadweight, falls into predetermined kind cave exactly, promptly finished the sowing task through earthing, suppression.
But the utility model unit uses, but also multimachine is also used.During sowing, be fixed in using method and operating procedure on the sower, basically with existing pneumatic seeder.
