Abstract
The utility model relates to a novel seed roller, which belongs to agricultural machinery and is a part on a seeder. A seed guide slot is arranged on the front side of a hole of the original hole type seed roller, and the diameter of a seed guide angle on the upper portion of the original hole type seed roller, thereby increasing efficiency of feeding seeds into the hole of the original hole type seed roller when in operation of the seeder, reducing miss seeding and increasing germination rate of the seeder in high-speed operation.
Description
Affiliated technical field
The utility model belongs to agricultural machinery, the part on the sower.
Background technology
The nest eye of the indent type seed wheel of present domestic sower all is to be inverted the truncated cones bodily form, top has one very little to advance kind of a lead angle, seed can only be advanced toward nest in the eyes by vertical direction, when the indent type seed wheel change fast the time, the nest eye seed that has does not come in just to have turned round, and causes broadcast leakage to cause being short of seedling.
Summary of the invention
The purpose of this utility model is the nest eye of a kind of new indent type seed wheel of design, when improving sower work, and the efficient that seed advances in the eyes to indent type seed wheel nest.Reduce the broadcast leakage phenomenon that causes when the indent type seed wheel changes soon, improve emergence rate.
The technical scheme that its technical problem that solves the utility model adopts is: 1, increase a seed guiding groove (4) in nest eye (3) front side of former indent type seed wheel (1).2, the diameter of kind of a lead angle (2) is advanced on nest eye (3) top of having strengthened former indent type seed wheel (1), has also just widened the width of seed guiding groove.
When indent type seed wheel (1) rotated, seed guiding groove (4) pushed away forward as a dustpan, can scoop up a part of seed come in, seed prolong seed guiding groove again slippage to nest eye (3) lining.Seed also can be entered nest eye (3) lining by the vertical direction of nest eye (3).[when the wheeled seed wheel of present domestic nest eye was worked, seed can only enter nest eye (3) lining by vertical direction].
The diameter of kind of a lead angle (2) is advanced on nest eye (3) top of having strengthened former indent type seed wheel (1), [diameter of kind of a lead angle (2) is advanced only greater than nest eye (3) upper diameter 3-4 millimeter in present domestic nest eye (3) top, this patent has expanded the 6-8 millimeter to, and [diameter as having strengthened the funnel upper end also can increase the efficient that seed advances to nest eye (3) lining.
The beneficial effects of the utility model are, after nest eye (3) improves, advance the efficient of seed when having improved sower work to nest eye (3) lining, and when the sower operating speed was high, [it is fast that indent type seed wheel (1) changes] can reduce the broadcast leakage phenomenon, improves emergence rate.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the front view of novel seed wheel
Fig. 2 is the left view of novel seed wheel
Among the figure 1, the indent type seed wheel; 2, advance kind of a lead angle; 3, nest eye; 4, seed guiding groove.
Embodiment
In embodiment illustrated in figures 1 and 2, as seen increased a seed guiding groove 4 in nest eye 3 front sides of former indent type seed wheel 1, what dilated diameter arranged at nest eye 3 tops advances kind of lead angle 2.During the sower operation, the top of indent type seed wheel 1 is full of seed, and when indent type seed wheel 1 prolonged among Fig. 1 the rotation of direction shown in the arrow, seed guiding groove 4 was scooped up forward as a dustpan, can scoop up a part of seed in seed guiding groove 4, and slippage is in nest eye 3 again.Seed also can enter 3 li of nest eyes by vertical direction, seed is advanced for 3 li to the nest eye by both direction simultaneously like this, just improved the efficient that seed enters 3 li of nest eyes, strengthened the diameter that advances kind of lead angle 2 on nest eye 3 tops in addition, also can improve to 3 li efficient of advancing seed of nest eye.
Above technical scheme reduced when changeing because of indent type seed wheel 1 is fast, and the nest eye 3 that the has phenomenon that seed has just turned round of not entering can improve emergence rate.
Claims (1)
1. novel seed wheel is characterized in that having increased a seed guiding groove (4) in nest eye (3) front side of former indent type seed wheel (1), and the diameter of kind of a lead angle (2) is advanced on nest eye (3) top of having strengthened former indent type seed wheel (1).
