Abstract
The utility model discloses a seeder with an automatic open-closed seed drop tube. The inner sides of the bottoms of two half cups are connected by an elastic piece, and when the seed drop tube is inserted into soil, the bottoms of the two half cups are opened by pressing an operation rod and then driving support rods, so that the seeds slide into the soil, and after the pressing force is released, the two half cups are closed under the action of the elastic piece. Only the pressing and releasing operations of the pressing operation rod are required to perform in each seed planting operation, so that the seeding planting operation is simple and the seed planting efficiency is improved.
Description
Technical field
The utility model relates to farming technical field, relates in particular to a kind of grain tube automatic folding-unfolding sower.
Background technology
Sower is to take crop seed to be the planting machinery of sowing object, for the sower of certain class or certain crop, often titled with crop species title, as grain drill, corn seeding drill, cotton planter, herbage seed broadcaster etc.During sower operation, by road wheel, drive seed wheel to rotate, the seed cup of seed in seed-box seeding quantity on request enters grain tube, and in plough falls into the groove of holding successfully, then by earthing compacting device, will plant subcovering compacting.Although developed a kind of seeding plough in prior art, after the sowing pipe being comprised of two and half cups inserts in soil, by pressing down action bars and driving support bar that two and half cup bottoms are opened, seed is slipped in soil, then by upper pulling process bar, drive support bar that two and half cups are closed.Yet, in once-through operation, need to press down and two actions of upper pulling process bar complicated operation, impact sowing efficiency.
Utility model content
In order to solve the technical problem existing in background technology, the utility model proposes a kind of grain tube automatic folding-unfolding sower, simplified operating procedure, improved sowing efficiency.
A kind of grain tube automatic folding-unfolding sower the utility model proposes, comprising:
Frame;
Seed cup, is arranged in described frame;
Grain tube, by first half cup the second half cup, formed, described grain tube upper end is communicated with described seed cup, the spout part of described grain tube is connected by removable pin, rotate around described removable pin the upper end of described the first half cup and described the second half cup, and the bottom of described the first half cup and described the second half cup is opened or closure;
Elastic component, two ends respectively symmetry are fixed on described two half cup inwalls, for making under described two half cup normalities in closure state;
At least two support arms, symmetry is fixed on two half cup inwalls respectively;
Action bars, is connected with described support arm.
Preferably, described grain tube is cone structure.
Preferably, described grain tube is column structure.
Preferably, described elastic component is spring.
Preferably, comprise two support arms, be respectively the first support arm and the second support arm, described elastic component two ends be separately fixed on described the first support arm, described the second support arm and described the first half cup, described the second half cup fixing point or under.
In the utility model, in two and half inner sides, cup bottom, use elastic component to connect, after sowing pipe inserts in soil, by pressing down action bars and driving support bar that two and half cup bottoms are opened, seed is slipped in soil, and after discharging downforce, two and half cups are closed under elastic component effect; In once-through operation, only need to press down and release presses down two actions of action bars, simple to operate, improved sowing efficiency.

Embodiment
Below in conjunction with accompanying drawing and by embodiment, further illustrate the technical solution of the utility model:
As shown in Figure 1 to Figure 2, Fig. 1 is the structural representation of a kind of grain tube automatic folding-unfolding sower that the utility model proposes; Fig. 2 is the grain tube that the utility model proposes structural representation while closing; Fig. 3 is the grain tube that the utility model proposes structural representation while opening.
Referring to figs. 1 through Fig. 3, the utility model embodiment provides a kind of seeding plough, comprising: frame 1; Seed cup 2, is arranged in described frame 1, for holding seed to be sowed; Grain tube 3, by the first half cup 31 and the second half cup 32, formed, grain tube 3 upper ends are communicated with described seed cup 1, seed to be sowed is used for annotating, the spout part of grain tube 3 is connected by removable pin 5, the spout part of the first half cup 31 and the second half cup 32 can rotate around removable pin 5, and the bottom of the first half cup 31 and the second half cup 32 can be opened or closure.Elastic component 6, spring for example, two ends respectively symmetry are fixed on two half cup inwalls (can on the first support arm 41 and the second support arm 42 and half cup fixing point or under), for making under two half cup normalities in closure state.At least two support arms (for example the first support arm 41 and the second support arm 42), symmetry is fixed on two half cup inwalls respectively; Action bars 4, is connected with the second support arm 42 with described the first support arm 41, for operation, struts or strain support arm, when action bars 4 presses down, makes two support arms strut two half cups, and while discharging downforce, two half cups are closed under the active force of elastic component 6.Wherein, grain tube 3 can be cone structure, can be also column structure.Seed cup is up big and down small trapezium structure.
During operation, seed enters grain tube 3 from seed cup 2, grain tube 3 is inserted in soil, by action bars 4, press down, the first support arm 41 and the second support arm 42 are strutted the first half cup 31 and the second half cup 32 bottoms, seed slips in soil, and grain tube 3 is extracted to soil, and surrounding soil can cover this hole; Then discharge downforce, the first half cup 31 and the second half cup 32 bottoms are closed under elastic component 6 active forces, continue to enter the seed sowing that circulates.
The utility model embodiment provide the above; it is only preferably embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; according to the technical solution of the utility model and utility model design thereof, be equal to replacement or changed, within all should being encompassed in protection domain of the present utility model.
