Referring to figs. 1 and 2, the utility model embodiment provides a kind of compound seeder, including rack 10, bracket 20, press wheel 30 and plough 40, bracket 20 are pivotally mounted to the rear of rack 10, and press wheel 30 and plough 40 are installed on The lower section of bracket 20 is provided with lifting assembly 50 between rack 10 and bracket 20.

Lifting assembly 50 includes linking arm 501, mounting base 502, sliding block 503 and screw rod 504.

501 bottom end of linking arm is installed on bracket 20；Mounting base 502 is set in rack 10, is offered in mounting base 502 The cushion hole 5021 of long waist shaped；Sliding block 503 is set in mounting base 502, and slidably along cushion hole 5021；504 one of screw rod End is connected to linking arm 501, and the other end is connected to sliding block 503.

It is at an angle between linking arm 501 and bracket 20 in the technical solution, in 504 rotation process of screw rod, make It for the top of linking arm 501, is driven by leverage and is lifted on bracket 20, so that press wheel 30, plough 40 etc. are detached from ground Face.

In seeder traveling process, since ground is inevitably uneven, it can generate and jolt, bracket 20 is caused to swing up and down, hold Easily rack 10 is driven to shake.This case provides certain buffer distance by the cushion hole 5021 of long waist shaped, swings in bracket 20 Cheng Zhong will not impact rack 10, guarantee the stability of seeder entirety, while improve the service life of bracket 20.

Further, press wheel 30 is set to the rear of plough 40, and in seeder traveling process, plough 40 is to ground Cutting forms groove, and to seeding or fertilizer, press wheel 30 is to carry out suppression landfill to the groove after sowing or fertilising.This case In front and back direction for advancing when referring to seeder work.

In one embodiment, it is threadedly engaged between screw rod 504 and sliding block 503, is rotated between screw rod 504 and linking arm 501 Connection.

In the technical solution, idle running between screw rod and linking arm 501, relative displacement is constant, between screw rod and sliding block 503 It is threadedly engaged, in screw rod rotation process, the distance between mounting base 502 and linking arm 501 can be changed, to realize bracket 20 The adjusting of angle.In an inactive state, bracket 20 can be lifted by adjusting screw rod, is readily transported movement.

Further, screw rod 504 has the section of rectangle close to one end of linking arm 501.

In the technical solution, by the section of rectangle (containing rectangular), it can turn in order to pass through the tool drives screw rods such as spanner It is dynamic.

In one embodiment, elastomer 60 is additionally provided between rack 10 and the upper surface of bracket 20.

During bracket 20 is swung up and down, although long lumbar hole can provide certain swing space, sliding block 503 with Long lumbar hole hits also the service life that certainly will will affect mounting base 502 back and forth for a long time.

This case acts on 20 upper surface of bracket by an elastomer, and when bracket 20 is swung up and down, elastomer is played centainly Buffer function reduces collision of the sliding block 503 to long lumbar hole.

In one embodiment, elastomer can be spring.

Further, bracket 20 includes that a crossbeam 201 and multiple multiple stringers 202 being set side by side, crossbeam 201 rotate in In rack 10, stringer 202 is installed on crossbeam 201, and the lower section of each stringer 202 is separately installed with press wheel 30 and plough 40。

In the technical solution, each stringer 202 respectively corresponds a seeding groove, in seeder traveling process, Ke Yitong Shi Shixian multiple row trench digging, sowing and fertilising.

Further, elastomer 60 is an elastic plate being laterally extended, which acts on all stringers 202 simultaneously Upper surface.

In the technical solution, all stringers 202 are acted on simultaneously by an elastic plate, it is at low cost.

In one embodiment, elastic plate is rubber slab.

In one embodiment, the distance between elastomer 60 and stringer 202 are adjustable.

Further, screw rod 61 is provided between elastomer 60 and rack 10.

In the technical solution, by rotation the adjustable elastomer bottom end of screw rod 61 and 202 upper surface of stringer between away from From to adapt to different surface states.

In one embodiment, crossbeam 201 is square steel.

In the technical solution, crossbeam 201 is square steel structure, and one side intensity is high, on the other hand may be implemented stringer 202 with Firm installation between crossbeam 201.

In one embodiment, stringer 202 is square steel.

In the technical solution, stringer 202 is square steel, and one side intensity is high, on the other hand can be convenient press wheel 30 and opens The installation of ditch device 40.

In one embodiment, the lower section of rack 10 is additionally provided with walking ground wheel 71, site preparation roller 72, preceding plough 73, bottom Fertile fertilizer apparatus 74, the lower section of each stringer 202 are also equipped with feed mechanism for seed and mouth fertilizer fertilizer apparatus.

Further, site preparation roller 72, preceding plough 73 (being provided with base fertilizer fertilizer apparatus), walking ground wheel are (as preceding trench digging The press wheel of device) 71, set gradually before and after plough 40 and press wheel 30.

The complete course of work of the seeder of this case includes: that tractor is connected to the rack of seeder and drives seeder row Into in traveling process, site preparation roller carries out pears to ground first and ploughs, and realizes the smooth of ground, then over the ground by preceding plough Face fluting, while fertilizer being applied in slot by base fertilizer fertilizer applicator, and fertilizer is filled to Land leveling by walking ground wheel； It is further slotted again by plough 40 to ground, sowing and applying mouth fertilizer is realized by feed mechanism for seed and mouth fertilizer fertilizer applicator respectively, It is finally filled again by press wheel 30 smooth.

Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new The range of each embodiment technical solution of type.
