Description

The multifunctional agricultural sower

The utility model relates to a kind of agricultural seeder machinery, especially a kind of direct-connecter planter.

In the prior art, suspension type agricultural seeding machine common and tractor mainly is made up of frame, land wheel, press wheel, defeated kind of a leg, ditching foot, seed containing bucket and seeding unit.But because the seeding unit of existing sower mostly is fixedly recess formula seed wheel, only be suitable for sowing corn, and sow other crop seeding inequality, especially defeated kind of leg of load ditching foot is fixed on the frame, press wheel is connected on the land axle, suitable broadcast scope and be restricted, cause inconvenience to use.

The purpose of the utility model provides a kind of novel structure, suitable to broadcast scope wide, can select seeding method according to broadcasting crop, joins to connect and regulates Multifunction sower easy to use.

For achieving the above object, the technical scheme that the utility model is taked is: periphery wall is made in the seeding unit design of sower be shaped on uniform spiral shell shrinkage pool and join the adjustable seed wheel of even regulating plug screw, the degree of depth of regulating the seeding wheel shrinkage pool by the size and the requirement of broadcasting crop seed kind, seed wheel is joined and is connected in the seed containing bucket bottom and is connected in series with on the power transmission shaft, power transmission shaft is connected land wheel by sprocket wheel with chain, drives seed wheel rotation carrying out seeding operation by land wheel; Defeated kind of a leg is that adjustable defeated kind of leg cooperates load in frame, can be according to the position of defeated kind of the leg of sowing needs adjustment; And the perpendicular pipe of frame load land axle made be telescopic adjustable sleeve pipe, can go into the ground degree of depth by what the height of regulating the perpendicular sleeve pipe of land axle was correspondingly regulated ditching foot on defeated kind of the leg, be suitable for the high-efficient homework of sower.

The utility model can be according to traction power, is made for 2 sowers that walk to 8 row structures, and will be designed to bullet formula wheel with the press wheel of tandem shafts with land wheel and can change with ground concave and convex ground town and press; Also be equipped with wheel shaft and weed ground, the operation of hoe ground in order to the equipped land wheel that weeds at the frame afterbody.

Because seeding unit of the present utility model has adopted the seed wheel of the adjustable shrinkage pool degree of depth, defeated kind of leg has adopted the bindiny mechanism that can adjust the position and has regulated the perpendicular connection pipe of telescopic land axle that plough is gone into the ground degree of depth, can also be equipped with and weed land wheel.The quite existing sower novel structure of the utility model, reasonable in design, can adjust line-spacing, seeding quantity and sowing depth according to requirement of seeding, improve seeding accuracy effectively and broadcast line amplitude, also enlarged the scope of application, be applicable to crop seeding such as corn, soybean, wheat, Chinese sorghum, peanut, cereal, and can directly sow on crop cover ground, also can weed ground, hoe ground, broadcast to fertilize, the energy a tractor serves several purposes, has multiple function, applied widely, equipped easy to use, be a kind of novel agricultural seeder machinery.
