Abstract
The utility model relates to a semi-precision wheat seeder, which is composed of a seed discharging box, a blocking sleeve, a seed discharging wheel, a wheel rim, a grooved wheel, a washing brush, a seed stopping board, and a seed discharging wheel sleeve. The seed discharging wheel is formed into a helical shape, and the end part of the seed discharging wheel is provided with the wheel rim. The grooved wheel is arranged on the wheel rim, and the groove of the grooved wheel and the groove of the seed discharging wheel are arranged alternatively. The utility model has the advantages of good seeding uniformity, and low crashing ratio. The utility model is an ideal substitute for the existing seeder.
Description
The utility model belongs to agricultural mechanical field, is specially adapted to a kind of new construction of seeding unit on the wheat half-precision seeding machine.
The domestic seeding unit that is used for the wheat semi-accuracy seeding has various ways at present, the 16 groove skewed slot bottom delivery feeds that the cone disk type seeding unit that row's formula seeding unit on the 16 groove straight troughs of being developed as Zhucheng, Shandong agricultural machinery, 16 groove straight trough bottom delivery feeds that Shandong Province's agricultural machinery is developed, the BJM-6-II type precision grain drill of wheat that Beijing's agricultural machanization is developed use and Shandong Province's agricultural machinery are developed, the seeding preferably of these seeding units, the uniformity is bad in the ground but also there is seed, the breakable defective of seed.
The purpose of this utility model is: design a kind of novel seeding unit, it not only can reach the semi-accuracy seeding of wheat, and can improve the uniformity minimizing percentage of damage of sowing.
The purpose of this utility model is achieved in that seed wheel is designed to the helical groove shape, the end of seed wheel is a garden shape wheel rim, the drop center wheel that connects a gear-like on the wheel rim, the recess of drop center wheel is corresponding with the spiral salient of helical form seed wheel and number equal, forms the staggered groove of garden shape wheel rim of being separated by.
Fig. 1 is the seeding unit structural representation
Fig. 2 is a seeding unit seed wheel structural representation
Following structure accompanying drawing is further introduced the utility model embodiment:
Seeding unit is made up of seeds discharging box 1, feed cutoff 2, seed wheel 3, wheel rim 4, groove 5, clear brush 6, seed retaining plate 7 and the seed wheel cover 8 of planting, seed wheel 3 is inserted on 8, can adjust the length of seed wheel 3 in seeds discharging box by regulating feed cutoff 2, the control seeding quantity, seeding brush 6 is with under the unnecessary seed brush that enters in the seeds discharging box on the seed wheel 3, guarantee the precision of sowing, seed is filled in the type hole slot of seed wheel 3 after entering in the seeds discharging box 1, after clear kind brush 6 clear kinds, rotation with seed wheel evenly falls into, and discharging tube falls in the seed furrow in field with plough.
The utility model seeding uniformity is good, when amount of seed metering hour, can be used as Precision Seeding, the amount of broadcasting is smart drilling state when increasing, the seed percentage of damage is nearly zero, and when the 450-150Kg/ hectare was broadcast weight range, each row discharge capacity uniformity coefficient of variation of average index was 1.45%, it is 0.51% that total displacement is stablized the coefficient of variation, and percentage of damage is zero.
Claims (2)
1, a grow wheat semi-accuracy seeding device, overlap 8 and form by seeds discharging box 1, feed cutoff 2, seed wheel 3, wheel rim 4, drop center wheel 5, clear kind brush 6, shelves kind plate 7, wheel, it is characterized in that: seed wheel 3 is the Cylinder of band helical groove 9, and its end has wheel rim 4 to connect a gear-like drop center wheel 5 at the wheel rim opposite side.
2, according to a grow wheat semi-accuracy seeding device of claim 1, the lug boss of the helical groove 9 on the recess 10 that it is characterized in that described drop center wheel 5 and the seed wheel 3 is corresponding, interlaced arrangement, and both sides groove number equates.
