Abstract

The utility model discloses a seed discharge device which is a hole sowing seed discharge device; the structure of the utility model comprises a seed discharge wheel, a sowing quantity adjusting plate, a sowing body, a baffle plate and a tension spring; the right part of the seed discharge wheel is in a seed discharge body, and the left part is extended out of the seed discharge body; the baffle plate forms a circular arc shape, the width of the baffle plate is wider than that of a seed discharge nest on the seed discharge wheel, the upper end of the baffle plate is fixedly connected with the upper end of the seed discharge body, the lower end is connected with the lower part of the seed discharge body through the tension spring, and the arc surface of the baffle plate covers on the left part of the seed discharge wheel; the utility model has the advantages of simple structure, light weight, low cost and convenient operation and can realize the precision sowing of seeds of a plurality of crops.

Description

The bunch planting seeding unit

The utility model relates to a kind of dispenser, definite a kind of bunch planting seeding unit of saying so.

In " rice seedling throwing seedling tray seeder " (patent No. 982096925) of applicant's application in 9 years, described seeds elimination structure mainly comprises arc comb scale plate, cochlear seed wheel and works the baffle plate of the amount of broadcasting corrective action, this structure has solved the regular drill structure and has cracked the seed phenomenon between the teeth, but this mechanism's weight is big, cost is higher, and can't realize bunch planting.

At above-mentioned defective, it is a kind of simple in structure, in light weight, cheap that goal of the invention of the present utility model is to provide, and can realize the bunch planting seeding unit of bunch planting.

The technical scheme of utility model is achieved in that the structure of bunch planting seeding unit comprises seed wheel, and the amount of broadcasting is adjusted plate, seeding body, baffle plate, extension spring; The amount of broadcasting adjust plate in the seeding body, the upper right side of seed wheel; The right-hand part of seed wheel is in the seeding body, and that the left side stretches out in seeding is external; Baffle plate is circular arc, and its width is wider than the width of seeding nest on the seed wheel, fixedlys connected with seeding body top in the baffle plate upper end, and the lower end is connected with seeding body bottom by extension spring, and the cambered surface of baffle plate is covered on the left side of seed wheel.

The utility model is simple in structure, and is in light weight, cheap, easy to use, can realize the precise hole sowing of multiple kinds of crops seed.

Fig. 1 is the structure chart of bunch planting seeding unit;

1 seed wheel, 2 baffle plates, 3 extension springs, 4 amounts of broadcasting are adjusted plate, 5 seeding bodies, 6 seeds, 7 seeding nests;

Fig. 2 is the end view of bunch planting seeding unit.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.

As shown in Figure 1, 2, the structure of bunch planting seeding unit is: the amount of broadcasting adjust plate 4 in seeding body 5, the upper right side of seed wheel 1; The right-hand part of seed wheel 1 is in seeding body 5, and the left side stretches out in outside the seeding body 5; Baffle plate 2 is circular arc, and its width is wider than the width of seeding nest 7 on the seed wheel 1, fixedlys connected with seeding body 5 tops in baffle plate 2 upper ends, and the lower end is connected with seeding body 5 bottoms by extension spring 3, and the cambered surface of baffle plate 2 is covered on the left side of seed wheel 1.

During work, the bunch planting seeding unit is installed under the kind case of sower, seed 6 enters in the seeding body 5, enters in the seeding nest 7 of right-hand part on the seed wheel 1 again, rotation along with seed wheel 1, seeding nest 7 forwards the left part of seed wheel 1 to seed 6, and baffle plate 2 covers on seed wheel 1 being close under the effect of extension spring 3, and seed 6 can not dropped out from seeding nest 7, when going to seed wheel 1 lower left quarter position, do not have baffle plate 2 to cover herein, seed 6 is discharged outside the body, realizes bunch planting.

Claims

1, bunch planting seeding unit, structure comprise seed wheel (1), and the amount of broadcasting is adjusted plate (4), seeding body (5); The amount of broadcasting adjust plate (4) in seeding body (5), the upper right side of seed wheel (1); It is characterized in that: its structure also comprises baffle plate (2), extension spring (3); The right-hand part of seed wheel (1) is in seeding body (5), and the left side stretches out in outside the seeding body (5); Baffle plate (2) is circular arc, its width is wider than the width that seed wheel (1) is gone up seeding nest (7), fixedly connected with seeding body (5) top in baffle plate (2) upper end, the lower end is connected with seeding body (5) bottom by extension spring (3), and the cambered surface of baffle plate (2) is covered on the left side of seed wheel (1).
