Abstract
The utility model provides a can improve seeding homogeneity seed evener that falls, mainly comprises housing and four buffer blades, installs according to the motion bounce-back characteristic of seed on the inboard curb plate of seed evener that falls, and the seed whereabouts in-process can alleviate the seed metering pulsation phenomenon that outer sheave seed metering ware caused after the buffering of different numbers of times, makes the seed successively even fall in kind of ditch, can effectively improve the seeding homogeneity of outer sheave seed metering ware.
Description
Affiliated technical field
The utility model relates to a kind of kind of the uniform device that falls that improves drilling grain seeder seeding uniformity.
Background technology
Seeding unit is the core component of grain seeder.The cereal seeder depositing seed of China adopts the outer groove wheel seeding unit more at present, this seeding unit has simple in structure, use easy to adjust, the characteristics that versatility is good. but external feed is the pushing effect seeding by groove, the groove structure of sheave has caused pulsation phenomenon in the seeding process, this is a big defective of external feed.The method that someone proposes to overcome pulsating nature can change straight trough into skewed slot or helicla flute, since in the actual seeding operation active length of outer groove-wheel often account for total length half or 1/3rd, therefore the effect that reduces pulsation is not clearly, is still to occur again and again being short of seedling or non-uniform phenomenon that seedling is too dense after seed falls into kind of ditch.Along with the development of agricultural cience and farming techniques and improving constantly of crop yield, more and more high to the seeding quality requirement of sower, for the drilling crop, require seed in the kind ditch of field, evenly to distribute, can effectively reduce seedling contention nutrient, can improve grain yield.Though the development of precision sower is also arranged now, does not still reach extensive popularization for various reasons.The utility model is mounted on the existing outer groove wheel seeding unit and is connected with seeds discharging box, and seed improves seeding uniformity through the buffering of different number of times.
Summary of the invention
In order to overcome existing external feed because the defective that the uneven sowing that pulsation phenomenon causes is spared, the utility model has designed a kind of Seeding Equalizer that improves seeding uniformity according to the kinetic characteristic of seed, through after the difference buffering number of times, seed evenly drops in kind of the ditch with different time order and functions seed after seeding unit is discharged.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model and seeds discharging box link, and mainly are installed in the assigned position of Seeding Equalizer by differing tilt angles by case and four buffer substrate tablets.Prove with correlation computations according to test of many times: first and third grade of buffer substrate tablet is installed in a side in the case by the angle that becomes 30 ° ~ 45 ° with level, second, the level Four buffer substrate tablet by with level at 45 ~ 60 ° angle is installed in opposite side in the case.Seed is after discharging from seeding unit, most of seed collision first-level buffer sheet, the speed of seed slows down after the collision first-level buffer sheet, through the later seed of first-level buffer sheet bounce-back, part collision level 2 buffering sheet, a part falls from the space of level 2 buffering sheet side bumps on three grades of buffer substrate tablets or does not bump three grades of buffer substrate tablets, directly falls or bumps on the level Four buffer substrate tablet.After the buffering by above different number of times, the order that seed just can be different successively evenly drops in kind of the ditch.
The beneficial effects of the utility model are: can effectively improve the seeding uniformity of outer groove wheel seeding unit, and simple in structure, easy to install.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a front view of the present utility model.
Fig. 2 is the end view of Fig. 1.
1. level Four buffer substrate tablets among the figure, 2. level 2 buffering sheet, 3. first-level buffer sheet, 4. three grades of buffer substrate tablets, 5. cases
The utility model directly is connected with seeds discharging box, motion rebounding characteristic according to seed, first-level buffer sheet (3), three grades of buffer substrate tablets (4) are installed in a side in the case (5) by the angle that becomes 30 ° ~ 45 ° with level, level 2 buffering sheet (2), level Four buffer substrate tablet (1) by with level at 45 ~ 60 ° angle is installed in the interior opposite side of case (5).The seed of being discharged by external feed directly falls into Seeding Equalizer, most of seed collision first-level buffer sheet (3), fraction does not collide first-level buffer sheet (3), direct collision level 2 buffering sheet (2) or three grades of buffer substrate tablets (4) or level Four buffer substrate tablet (1) or directly fall into inoculated tube, collide the later seed of first-level buffer sheet (3) through bounce-back, part collision level 2 buffering sheet (2), a part three grades of buffer substrate tablets of direct collision (4) or level Four buffer substrate tablet (1) or directly fall, part collision three grades of buffer substrate tablets (4) through level 2 buffering sheet (2) bounce-back, part direct collision level Four buffer substrate tablet (1) or directly fall, seed part collision level Four buffer substrate tablet (1) after three grades of buffer substrate tablets (4) bounce-back, a part directly falls, through after a series of bufferings, the suffered buffering number of times of seed is respectively 0 time, 1 time, 2 times, 3 times, 4 times unequal, seed is every, and speed all can have minimizing to a certain degree through once cushioning, so seed just can successively drop in kind of the ditch uniformly.
Claims (2)
1. Seeding Equalizer, it is characterized in that: the narrower both sides of case are acuter angles, and the both sides of broad are parallel construction, and several buffer substrate tablets are different angles and are installed on both sides narrower in the case.
2. Seeding Equalizer according to claim 1, it is characterized in that: the first-level buffer sheet, three grades of buffer substrate tablets become 30 ° ~ 45 ° angle to be installed in a side in the case with level, and level 2 buffering sheet, level Four buffer substrate tablet and level be at 45 ~ and 60 ° angle is installed in the interior opposite side of case.
