Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the present embodiment comprises dress seed case 10, seed-guiding pipe 2, guide pipe 11, gradation pipe 7, gradation pipe-in-pipe 6, connecting rod 15, bent axle 16, roller 17, plough 19, spring 13, handrail 1 and support bar 3; Be inclined-plane bottom dress seed case 10, inclined-plane lowest part is provided with circular open 8, and open lower end is located at by guide pipe 11; Gradation pipe-in-pipe 6 is sheathed on outside gradation pipe 7, and upper end is placed in guide pipe 11; Gradation pipe 7 upper end is inclined-plane, lower end and connecting rod 15 hinged, connecting rod 15 lower end and bent axle 16 hinged, bent axle 16 two ends are provided with roller 17; Handrail 1 is two, is symmetrically set on bent axle 16, hinged with bent axle 16; Sidewall dress seed case 10 being positioned at bottom opening homonymy is provided with leads seed hole 9, seed-guiding pipe 2 upper end with lead seed hole 9 and be communicated with, lower end connection plough 19, is equipped with support bar 3 between plough 19 and handrail 1 and between handrail 1 and guide pipe 11; Gradation pipe 7 lower end is also provided with annular boss 14, and spring 13 is located between gradation pipe-in-pipe 6 bottom and annular boss 14, and gradation pipe-in-pipe 6 outer wall is provided with spacing chuck 5.
In the present embodiment, when the section that bent axle 16 is connected with connecting rod 15 is positioned at minimum point, the peak on gradation pipe 7 sleeve upper end and gradation pipe 7 inclined-plane overlaps with guide pipe 11 upper end.Spacing chuck 5 upper surface equals the length of guide pipe 11 to the distance of gradation pipe-in-pipe 6 upper end and gradation pipe-in-pipe 6 upper end to the difference leading seed hole 9 distance.
In the present embodiment, gradation pipe-in-pipe 6 outer wall is provided with longitudinal spacing elongated hole 4, the length of spacing elongated hole 4 equals the vertical height on inclined-plane, gradation pipe 7 upper end, position corresponding with spacing elongated hole 4 on gradation pipe 7 is provided with stop screw 12, stop screw 12 is through spacing elongated hole 4, can vertically move in spacing elongated hole 4, and when the section that bent axle 16 is connected with connecting rod 15 is positioned at minimum point, stop screw 12 is positioned at spacing elongated hole 4 bottom.
In the present embodiment, the wall of leading place, seed hole 9 is vertical plane, and the inclined-plane of gradation pipe 7 upper end is towards leading side, seed hole 9.
In the present embodiment, guide pipe 11 internal diameter is equal with the internal diameter of dress seed case 10 bottom opening.
In the present embodiment, the support bar 3 between plough 19 and handrail 1 is L shape bar, and the vertical section 18 that L shape bar is connected with handrail 1 is telescopic rod.
Below describe the gradation sowing operation principle of this device in detail:
As shown in Figure 1, in use, seed is loaded in dress seed case, ensure that one deck seed is being led below seed hole topmost.Promoting handrail makes whole device move forward, and the scrolling bands dynamic crankshaft of roller rotates, and crank rotation namely promotes gradation pipe by connecting rod and gradation pipe-in-pipe moves up and down.
Because gradation pipe upper surface is inclined-plane, therefore can form a wedge shape space between inclined-plane and gradation pipe-in-pipe sidewall, according to the size of different types of seed, one or many seeds in this wedge shape space, can be held.
Under original state, the position that bent axle is connected with connecting rod is positioned at minimum point, the top of gradation pipe and gradation pipe-in-pipe is positioned at dress seed case bottom opening place, simultaneously owing to being also provided with spring between gradation pipe-in-pipe lower end and annular boss, therefore when bent axle promotion connecting rod moves upward time, gradation pipe moves upward, and promotes gradation pipe-in-pipe be simultaneously upwards synchronized with the movement by spring.In an initial condition, because the peak on gradation pipe-in-pipe upper end and gradation pipe inclined-plane overlaps with guide pipe upper end.Spacing chuck upper surface to the distance of gradation pipe-in-pipe upper end and gradation pipe-in-pipe upper end to lead seed pitch-row from difference equal the length of guide pipe, therefore after when gradation pipe-in-pipe, topmost seed hole is led in arrival, spacing chuck contacts with bottom guide pipe, gradation pipe-in-pipe is stoped to continue to move upward, now gradation pipe can continue to move upward, because the length of spacing elongated hole is equal with the vertical height on gradation pipe inclined-plane, therefore, when inclined-plane minimum point exceedes gradation pipe-in-pipe upper surface, stop screw arrives the top of spacing elongated hole.Gradation pipe stops moving upward, and now gradation pipe inclined-plane is with to lead seed hole just relative, and the seed in the wedge shape space between inclined-plane and gradation pipe-in-pipe sidewall slips into leads seed hole, and slides along seed-guiding pipe, enters in the soil opened by plough.
Complete a gradation after planting, bent axle is rotated further, and drives gradation pipe to move downward, when the stop screw on gradation pipe arrive spacing elongated hole bottom after, stop screw drives gradation pipe-in-pipe to move downward, until crank rotation is to minimum point.
In above process, because the part that L shape connecting rod is connected with handrail is telescopic rod, so no matter how handrail moves at vertical direction, can both ensure that plough does not depart from soil.Ensure the degree of depth that plough is digged.
In the above-described embodiments, spring upper end can also be made to be fixedly connected with gradation pipe-in-pipe bottom, and lower spring end is fixedly connected with annular boss, can arrange spacing elongated hole and stop screw thus, also can ensure that gradation pipe-in-pipe can normally reset downwards.
