Description

Single-wheel semiaxis direct conduction type sower

The utility model belongs to the agricultural machinery technology field, relates to a kind of improvement of sower.

At present, its structure of Jue Dabufen sower consists of the following components: frame, transmission, seeding, fertilizer, trench digging, earthing.More representational have two kinds as Fig. 1, shown in 2, first kind (shown in Figure 1) is two land wheels, a land wheel transmission seeding, a land wheel transmission fertilizer, ordinary circumstance is to drive seeding square shaft sprocket wheel by the sprocket wheel on the land axle, and the square shaft sprocket wheel drives each row seeding unit sprocket wheel, this kind of drive, the double row sowing machine needs nine sprocket wheels, the sprocket wheel machining accuracy is higher relatively, and this mode, then corresponding replacing sprocket wheel when needs change spacing in the rows, change the sprocket wheel of the different numbers of teeth, centre-to-centre spacing then changes, and need adjust regulating wheel again, to guarantee correct chain tension, the peasant in use, and is very inconvenient; Chain tension is improper, crossing pine then stops steathily, the tension feed shaft is yielding, all influence the accuracy of seeding, will guarantee the uniformity of seed level in addition, the different ground profilings that rise and fall of each planter reply, the centre of sprocket distance that drives the sprocket wheel of seeding unit during profiling and be fixed on the seeding square shaft changes, must have with profiling centre-to-centre spacing to change and the constant self-reacting device of chain tension, the unreliable same accuracy that influences seeding of this device work, it is very big usually therefore to sow the spacing in the rows variation.For avoid above problem to have adopting second kind (as shown in Figure 2) is that every capable monomer seeder all has two land wheels, by being fixed on four connecting rod profilings of frame, though this mode has overcome the shortcoming of chain drive, but two land wheels of each monomer, the double row sowing machine is added the support wheel of frames with regard to four land wheels, and full machine has four land wheels, because of the certain width of being separated by between land wheel, when needs are adjusted line-spacing, interfere mutually, can not adapt to the agriculture requirement of transferring row, and the cost height.

The purpose of this utility model provides a kind of single-wheel semiaxis direct conduction type sower.

The technical solution of the utility model is as follows:

Is connected with fertilizer apparatus with the wheel shape seeding unit by two semiaxis in central land wheel both sides, central land wheel and two semiaxis are in transmission connection fixingly by universal, directly drive seeding unit rotation seeding by the both sides semiaxis of central land wheel drive.

Board-like feeler is the board-like shape of sled.

The utility model has the advantages that: avoided chain drive and the transmission of monomer land wheel, simplified general structure, improved each parts service behaviour; The direct transmission of land wheel has increased reliable transmission, has improved the seeding accuracy; When changing spacing in the rows, easy to adjust; The cost cost is low.

Fig. 1 is two places wheel seeding and fertilizer transmission schematic diagram;

Fig. 2 is a monomer land wheel transmission schematic diagram;

Fig. 3 is main TV structure figure of the present utility model;

Fig. 4 is a side-looking structure chart of the present utility model;

Below in conjunction with accompanying drawing the utility model is described further:

Among Fig. 1: the 1st, land wheel, the 2nd, seeding square shaft, the 3rd, fertilizer square shaft, the 4th, fertilizer apparatus, the 5th, seeding unit, the 6th, seeding sprocket wheel, the 7th, row fat sprocket.Among Fig. 2: the 11st, support land wheel, the 12nd, monomer land wheel, the 13rd, planter.Among Fig. 3,4: the 21st, frame, the 22nd, fertile case, the 23rd, fertilizer transmission, the 24th, profiling four bars, the 25th, kind of case, the 26th, core beam, the 27th, packer, the 28th, fertilizer apparatus, the 29th, seeding unit, the 30th, central universal transmission mechanism, the 31st, land wheel, the 32nd, covering device, the 33rd, plough, the 34th, board-like feeler, the 35th, deep-fertilizing furrow opener, the 36th, semiaxis.

Adopt the direct transmission of central land wheel, it be support wheel be again the transmission land wheel, for adapting to two seeding monomers with the ground profiling, semiaxis adopts universal articulated, movable joint length can be adjusted, can adapt to the requirement of 40,60,65,70 centimetres four kinds sowing line-spacings, the elongation of movable joint semiaxis, shortening can be satisfied the different spacings agriculture requirement; Area is bigger contiguously than wheeled feeler for board-like feeler, and therefore the profiling limit is dark better.
