Abstract
A novel seed-metering device of a peanut seeder comprises a seed box (1), a feeding inlet (3), a transmission shaft (4), an outer shell (5), a seed-metering wheel (6), a seed-protecting piece (7) and a protective cover (9), and is characterized in that an elastic piece (2) is fixedly connected with the seed box (1), and the elastic piece (2) extends downward to the outer shell (5) provided with a hole and to an inner disk tank (10) of the seed-metering wheel (6). Therefore, the device is simple in structure and low in cost, can effectively solve multi-seed and no-seed problems, and meets uniformity of seeding quantity of various industries and uniformity of total seeding quantity.
Description
Technical field
The utility model relates to a kind of seeding apparatus of seeder, particularly a kind of peanut planter seeding unit.
Background technology
The peanut planter seeding unit that uses in vast farmland at present mainly is the seeding unit that outer groove-wheel colludes the formula structure, and this seeding unit is comprised of shell and seed wheel, and seed wheel can rotate, and the seed wheel inner disc is established seed distributing groove.The seeding unit of this structure finds that each row uniformity of seeding quantity and total amount of seed metering uniformity are unstable in the use procedure of field, exist uniformity coefficient low, such as many defective.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple and practical, the seeding unit that the amount of broadcasting stability is high.
Peanut planter seeding unit of the present utility model is by kind of case 1, feed opening 3, power transmission shaft 4, shell 5, seed wheel 6, protect kind of sheet 7 and protecting cover 9 forms.Seed wheel 6 is the cylinder type of end sealing, and preferably the 2-3mm gap is arranged with protecting between kind of the sheet 7, and sidewall is provided with at least one row's inner disc groove 10, establishes at least in the inner disc groove that 7-10 is individual to collude groove 11, protects kind of sheet 7 and is fixed on the protecting cover 9.It is characterized in that being fixedly connected with a shell fragment 2 at described kind of case 1 base plate with the mode of pressing plate, in the inner disc groove 10 of shell fragment down into the shell 5 that has the hole and seed wheel 6, described protect to be fixed with on kind of the sheet 7 plant clearly device 8.
A preferred plan of the present utility model is, described seed wheel 6 and protect best clearance 2mm between kind of the sheet 7, and inner disc groove 10 the bests are 2 rows, and 10 of every rows collude groove 11, and described shell fragment 2 is down into being preferably 5mm in the inner disc groove, and shell fragment is S-type.
The beneficial effects of the utility model are: 1, owing to establish and collude groove in the inner disc groove of seed wheel, the peanut kind by the inner disc groove freely enter collude groove can only one, make and only broadcast a peanut kind at every turn, can effectively solve many problem.2, owing to be provided with shell fragment at seed wheel; so both can push and colluded groove not entering the peanut kind of colluding groove; also can fall the unnecessary peanut kind bullet that is subject to the extruding of inner disc groove; effectively solve many or without the problem of grain; can satisfy the uniformity of each row seeding quantity uniformity and total seeding quantity; it is simple in structure, and cost is extremely low.
Description of drawings
Fig. 1 is the utility model structural representation, and Fig. 2 is the utility model Fig. 1 end view, and Fig. 3 is seed wheel inner disc groove structural representation.
Embodiment
This seeder seeding unit; comprise kind of case 1; feed opening 3; power transmission shaft 4; shell 5; seed wheel 6; protect kind of sheet 7 and protecting cover 9; protecting cover adopts toughened plastic to be processed into transparence; protecting kind of sheet 7 is screwed on the protecting cover 9; protect to be fixed with on kind of the sheet 7 and plant clearly device 8; protecting kind of sheet 7 outsides by seed wheel 6 of power transmission shaft 4 flexible connections; the seed wheel inner distance is protected kind of sheet 7 gap 2mm; the seed wheel outside is by shell 5 protections; shell adopts iron plate to be processed into circle; shell is provided with seed dropping hole 12; be fixedly connected with protecting cover 9; be fixedly connected with feed opening 3 in protecting cover 9 outsides, feed opening communicates with planting case 1, and described seed wheel 6 is the cylinder type of end sealing; be provided with two row's inner disc grooves 10 at sidewall; every row's inner disc groove is established 10 and is colluded groove 11, and the mode with pressing plate on kind case 1 base plate is fixedly connected with a shell fragment 2, and shell fragment is down into 5mm in the inner disc groove of the shell that has two holes and seed wheel.
During sowing, the peanut kind is at first planted case 1 enters seed wheel 6 inner discs bottom through feed opening 3 inner disc groove 10, seed wheel along with power transmission shaft 4 owing to the drive of outside sprocket rotation is rotated, the peanut kind is freely entered by inner disc groove 10 and colludes groove 11, each colludes groove and only contains a peanut kind, collude the outer unnecessary peanut kind of groove when going to the top by the bottom freely falling body fall into seed wheel 6 inner discs bottom, being subject to the peanut kind that inner disc groove extruding can not come off during rotation is then fallen unnecessary peanut kind bullet by the shell fragment 2 at seed wheel 6 tops, push and collude groove not entering the peanut kind of colluding groove, rotation along with seed wheel, the peanut kind enters protects kind of sheet 7, go to seed wheel 6 bottoms and enter seed dropping hole 12 by clear kind of device Final 8 system, finish sowing.By above process, so that the uniformity of the uniformity of every cave amount of seed metering and total amount of seed metering improves greatly.
