Description

Small-size multifunction agricultural apparatus

The utility model belongs to the agricultural machinery field, is suitable for wheat, soybean, peanut, corn seeding, harvesting, intertillage, deep placement chemical fertilizer.

At present, agricultural machinery is of a great variety, has large-scalely, also has small-sized; The drive of relying on oneself is arranged, also favourable usefulness manpower, animal power; Combine is arranged, the utensil of special purpose is also arranged.Though of a great variety, the combine class can be sowed exactly, the farm machinery that can gather in and intertill again lacks small-sized, and when sowing different cereal, changes the seeder trouble, needs to shut down and changes seeder, and this just brings inconvenience to use.In addition, this large-scale combine, incompatible rural area single household at present buys, and purchasing power does not reach.Single household buys single small-sized farm implements besides, and the kind that needs is many, preserves also to have certain problem.According to above situation, will design a kind of multiduty small-sized machine, satisfy present country practical situation needs.

The purpose of this utility model will design exactly and a kind ofly can sow wheat, soybean, and bunch planting peanut, corn can multi-row seedings during sowing, but also single file sowing, and that also can apply fertilizer and intertill be applicable to the small-scale agricultural machinery that present rural area needs.

The new major technique of this practicality adopts fabricated connection.The concrete seeder that two kinds of dissimilar tooth forms are housed at splined shaft, the two ends of seeder are by the pivot pin axial restraint, the engagement of sliding of the internal tooth piece at the two ends of seeder external tooth and seeder housing, the splined shaft of seeder is stirred by the fork that is contained on the support, is connected by pivot pin between splined shaft and the splined shaft; Be welded with two protruding geosynclinal blocks on the sowing pipeline, be bolted on the geosynclinal block on the frame square tube, carry out suit between square tube and the square tube by bolt; The housing of seeder is screwed on seed bucket, and seed bucket has upper bracket and lower carriage and square tube frame Bolt Connection, Bolt Connection is also arranged between upper bracket and support and the lower carriage, and the position of bolt hole is identical; The travelling wheel axle head is equipped with on the centre position of fanning strip has bolt and frame to be fixedly connected, and fan groove is arranged on the fanning strip, and adjustment screw is arranged in the groove; Be welded with two protruding blocks on the frame, porose on the piece, draw bar go here and there versatilely with the hole in; Connect with the polylith plate between the hand steered handle.

Advantage of the present utility model, owing to adopted the connection of assembling, splined shaft can be one, also can two, three, and the position of bracket holes and the hole of seeder housing, the hole on the seed bucket are the same with the hole site on the frame, with adjustable plate is arranged on the travelling wheel, therefore be applicable to the sowing of various types of grain, simultaneously can single file or multirow, can also apply fertilizer, purposes such as intertillage have reached the purpose that designs.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the A-A cutaway view of Fig. 2.

Fig. 2 is the B-B cross-section side view.

Fig. 3 is a frame plan.

Describe details of the present utility model and working condition in detail below in conjunction with Fig. 1, Fig. 2, Fig. 3.

Frame square tube (10) is that hollow square tube is made, and the two ends square tube is little, and it is big that middle square tube is wanted, and insert in the middle square tube at two ends, and fixing with screw (30).On frame square tube (10), (11), be fixed with seed tube (7), be stuck on square tube (10), (11) because be welded with fixture block (9) in seed tube, fixing with bolt (8).The lower end of seed tube (7) is connected to plough, top is connected to seed hopper (6), seed hopper top is connected to seeder housing (2), have recess on the housing, internal tooth piece (3) is housed in the recess, (4), internal tooth piece outside has gland (31) to use screw in compression, internal tooth piece (3), (4) with splined shaft (5) on seeder (32), (33) be meshed, and can endwisely slip, also can rotate with the engagement of seeder external tooth, seeder (32), (33) endoporus matches with splined shaft (5), seeder (32), (33) axially there is pin to be fixed on the splined shaft, splined shaft (5) has the fork frame (14) and the fork (15) that are fixed on the upper bracket (12) to stir, seeder (32), (33) the outer teeth groove on is to open according to a grain size of seed, resemble sowing wheat and use stria, it is serration, what a sowing grain was big uses thick groove, it is bastard, seed is just between cog, so seeder (32), (33) there is one to be serration in, there is one to be bastard, need not changes seeder, as long as stir the seed that fork just can be sowed two kinds of difference grains.Splined shaft (5) is used for radially fixedly seeder (32), (33), and the slip of seeder is to slide between internal tooth piece (3) and (4).There is pin (28) to connect between splined shaft (5) and the splined shaft.Seeder housing (2) and seed bucket (1) are by Bolt Connection.There is bolt (29) to be coupled to each other between seed bucket (1), upper bracket (12), lower carriage (13) and the frame, the position of bolt screw is identical, therefore, the need certain altitude that has upper bracket just arranged, the support of can dismantling that needs the low level sowing, do not need can all taking down support of support, change a pipeline (7) and just can use.The rotation of seeder (32), (33) is a key wheel (16) that splined shaft (5) arranged with the axle (19) of travelling wheel (27) on key wheel (34), link up by chain (17), as long as travelling wheel rotates, seeder also just rotates, and just can sow.Speed ratio between sprocket wheel (16) and the sprocket wheel (18) can be changed the sprocket wheel speed ratio according to the spacing requirement of tree seedling.Axle (19) end of travelling wheel (27) is equipped with fanning strip (20), axle (19) can rotate in fanning strip, fanning strip is fixed on the frame with bolt (21), deep-slotted chip breaker is arranged on the fanning strip, the height that bolt (21) adjusting travelling wheel (27) on the frame of being fixed on is arranged in the deep-slotted chip breaker, the trench digging depth of just regulating plough (35).This also is the requirement according to seed, still fertilising, and still intertillage is determined.Be welded with two protruding blocks (24) on the frame, have the hole on the piece, draw bar (25) go here and there versatilely with the hole in, this just can regulate the direction of tractive force.Connect only conveniently what single file sowing, or multi-row seeding, the adjusting that broadens of being convenient to narrow down of hand steered handle between the hand steered handle (26) with polylith plate (28).Simultaneously, during as intertillage, just can intertill as long as change ploughshare, when gathering in what, just can be as long as change bevel gear, chain, chain-wheel mechanism as harvesting.Said this apparatus is a multi-functional apparatus, and the generation of these functions all is the caused function of assembly structure feature.
