Background technology
Sower is a kind of agricultural machinery, sower structure mainly Seeding box connection plough sowing in prior art, earthing wheel earthing, sowing is completed in being buried by seed lid, but, high stub land or soil block excessive time, exist stalk be deposited in earthing wheel side, not only can not earthing, seed topsoil can be turned down and leak kind on the contrary; Meanwhile, when high seeding on unfallowing field, existing sower limits due to structure, the depth of uncontrollable sowing, causes sowing weak effect.
Utility model content
For overcoming the deficiencies in the prior art, the utility model provides one can effectively adjust the sowing depth, collection hack, earthing, suppression effect and multi-functional high stubble sower integrally.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of multi-functional high stubble sower, comprise frame, rack-mounted hanger bracket, Seeding box, be arranged on the plough of frame lower, is arranged on the land wheel of frame both sides by land axle, the soil covering barrel be connected by support bar with frame, between support bar and frame, be also provided with adjustable springs bar, gearbox connects Seeding box regulating shaft and land axle, and Seeding box connects plough by grain tube.
Further, described plough is made up of the trench digging bar be connected by U-shaped screw with frame and the seeding rod that connects bar of ditching, goes out kind of the body of rod at mouth place arranges symmetry to broadcast native cutter for a pair at seeding rod.
Further, described plough arranges multiple, in frame during many row's distributions, distributes in uniform crossover.
Further, rim of wheel outer surface in described ground is arranged some land wheels nail.
Further, described land wheel nail is the center of circle with land axle, is evenly distributed on ground rim of wheel outer surface.
Further, the radius ratio of described land wheel and soil covering barrel is 1:2.5.
Further, described soil covering barrel is arranged on earthing axle on support bar by the bearing block by support bar two ends and cylindrical shell forms, cylindrical shell is by the baffle plate being positioned at two ends and the connecting plate be positioned in the middle of cylindrical shell, and be connected to the hollowed-out cylinder structure of the cylindrical shell bar formation on two baffle plates and connecting plate, cylindrical shell bar is divided into straight-bar and V-arrangement curved bar, the central point of V-arrangement curved bar is positioned on connecting plate, towards body direction of travel.
Further, on the support bar between soil covering barrel and frame, near soil covering barrel position, be provided with grass stick.
Further, described grass stick is in-line towards soil covering barrel position, and support bar arranges some adjustment holes, for the adjustment of grass stick and soil covering barrel position.
Advantageous Effects of the present utility model is: the reasonable disposition of being taken turns by land wheel and earthing, and the design of plough, made it can freely adjust the sowing depth in high stub land, ensure that the quality of sowing; The design of adjustable springs bar, grass stick and soil covering barrel, makes it have hack concurrently, earthing, suppression is multi-functional in one, can not produce stalk jam.

Embodiment
The multi-functional high stubble sower of one as shown in Figure 1, comprise frame 1, rack-mounted hanger bracket 2, Seeding box 3, be arranged on the plough 4 of frame lower, be arranged on the land wheel 5 of frame both sides by land axle, the soil covering barrel 7 be connected by support bar 6 with frame, is also provided with adjustable springs bar 8 between support bar 6 and frame 1, gearbox 9 connects Seeding box 3 regulating shaft and land axle, and Seeding box 3 connects plough 4 by grain tube.
Described plough 4 is made up of the trench digging bar 41 be connected by U-shaped screw with frame and the seeding rod 42 that connects bar of ditching, goes out kind of the body of rod at mouth place arranges symmetry to broadcast native cutter 43 for a pair at seeding rod 42.
Described plough 4 arranges multiple, in frame 1 during many row's distributions, distributes in uniform crossover.Intersection before and after two rows is divided into be uniformly distributed in figure.This set depends on the line space of plantation seed demand.
Described land wheel 5 wheel rim outer surface is arranged some land wheels nail 51.
Described land wheel nail 51 is the center of circle with land axle, is evenly distributed on land wheel 5 wheel rim outer surface.
Described land wheel 5 is 1:2.5 with the radius ratio of soil covering barrel 7.Soil covering barrel under the stage clip pressure of adjustable springs bar, rolls with earth surface, and ground wheel diameter is 2.5 times of soil covering barrel diameter, and the rotating speed of soil covering barrel is more than 2 times of ground wheel speed, thus effectively improves hack, earthing, suppression effect.
Described soil covering barrel 7 is arranged on earthing axle 71 on support bar by the bearing block by support bar two ends and cylindrical shell 72 forms, cylindrical shell 72 is by the baffle plate 73 being positioned at two ends and the connecting plate 74 be positioned in the middle of cylindrical shell, and be connected to the hollowed-out cylinder structure of cylindrical shell bar 75 formation on two baffle plates and connecting plate, cylindrical shell bar 75 is divided into straight-bar and V-arrangement curved bar, the central point of V-arrangement curved bar is positioned on connecting plate, towards body direction of travel.
On support bar 6 between soil covering barrel 7 and frame 1, near soil covering barrel 7 position, be provided with grass stick 10.
Described grass stick 10 is in-line towards soil covering barrel 7 position, and support bar 6 arranges some adjustment holes, for the adjustment of grass stick and soil covering barrel position.
The reasonable disposition that the utility model is taken turns by land wheel and earthing, and the design of plough, make it can freely adjust the sowing depth in high stub land, ensure that the quality of sowing; The design of adjustable springs bar, grass stick and soil covering barrel, makes it have hack concurrently, earthing, suppression is multi-functional in one, can not produce stalk jam.
Above embodiment is the explanation to the utility model content, not as the restriction to the utility model content, every those skilled in the art on basis disclosed in the application without creationary variation, all in the protection domain of the application.
