Description

Combined type nest eye is adjustable, and corn seeding is taken turns

Technical field

The utility model belongs to agricultural machinery, relates generally to the indent type seeding wheel that a kind of corn seeding operation uses.

Background technology

The wheeled corn seeder of nest eye is one of current the most widely used mechanical seeder in northern China corn planting area, and this device not only achieves corn simple grain precise sowing, but also adapts to and meet quick seeding operation needs.But, because the nest eye seeding wheel adopted in the wheeled corn seeder of existing nest eye is monolithic construction design, namely kind of a nest eye size of filling on nest eye seeding wheel immobilizes, unadjustable change, significantly declines to the adaptive capacity of different cultivars corn seed, need select different nest eye wheels when peasant purchases machine for corn variety, or during product export, be equipped with the nest eye seeding wheel of multiple not brood eye size, namely inconvenient peasant uses, and in turn increase and purchase machine cost, adaptive capacity is poor.

Summary of the invention

The purpose of this utility model is exactly for above-mentioned prior art Problems existing, and research and design provides a kind of combined type nest eye adjustable corn seeding wheel, reaches easy to use, expands adaptive capacity, reduces the object purchased machine cost, improve service efficiency.

Basic Design of the present utility model is: the suit follower of along the circumferential direction rotatable adjustment on the sidepiece of driving wheel, along the circumferential direction uniform separately on the relative inner end face of described driving wheel and follower rectangular boss is set, inserting overlaps coordinates in misplacing for rectangular boss on described driving wheel and the rectangular boss on described follower, the rectangular boss of described driving wheel is offered driving wheel half arc nest eye, in the rectangular boss of described follower, follower half arc nest eye is offered at the position of matching with driving wheel half arc nest eye, the degree of depth of described follower half arc nest eye and width dimensions are all less than the degree of depth and the width dimensions of driving wheel half arc nest eye, and described follower half arc nest eye along the circumferential direction can be inserted in driving wheel half arc nest intraocular part cooperatively interacts, form overall adjustable nest ocular structure, driving wheel along the circumferential direction arranges several semicircular arc endoporus, from described several semicircular arc endoporus one end, between adjacent semicircular arc endoporus, spacing reduces successively gradually, on follower along the circumferential direction and arrange several semicircular arc exit orifice with semicircular arc endoporus mated position place, between described several semicircular arc exit orifice is adjacent, spacing is equal, described driving wheel outer face is installed the spring bearer plate with regulating alignment pin, described adjustment alignment pin can be inserted in the circular hole of the semicircular arc inner/outer hole formation cooperatively interacted successively, complete lock in place along the circumferential direction between driving wheel and follower, so far form the adjustable corn seeding wheel of combined type nest eye.

Traditional monoblock type nest eye seeding wheel is changed over the adjustable seeding wheel of combined type nest eye by the utility model, namely one device meets and has adapted to the seeding operation needs of different corn seed, has the feature that Precision Seeding seeding operation uses, adaptable, service efficiency is high that novel in structural design is reasonable, sowing nest eye adjustment simple and convenient, degree of regulation are high, can adapt to various corn variety seeds.

Accompanying drawing explanation

Fig. 1 is combined type nest eye adjustable corn seeding wheel general structure schematic diagram;

Fig. 2 is the left-hand view of Fig. 1.

In figure, piece number illustrates:

1, driving wheel, 2, follower, 3, spring bearer plate, 4, regulate alignment pin, 5, follower half arc nest eye, 6, driving wheel half arc nest eye, 7, semicircular arc endoporus, 8, semicircular arc exit orifice.

Embodiment

Below in conjunction with accompanying drawing, the utility model optimum implementation is described in detail.The adjustable corn seeding of a kind of combined type nest eye is taken turns, the suit follower 2 of along the circumferential direction rotatable adjustment on the sidepiece of driving wheel 1, along the circumferential direction uniform separately on the relative inner end face of described driving wheel 1 and follower 2 rectangular boss is set, inserting overlaps coordinates in misplacing for rectangular boss on described driving wheel 1 and the rectangular boss on described follower 2, the rectangular boss of described driving wheel 1 is offered driving wheel half arc nest eye 6, in the rectangular boss of described follower 2, follower half arc nest eye 5 is offered at the position of matching with driving wheel half arc nest eye 6, the degree of depth of described follower half arc nest eye 5 and width dimensions are all less than the degree of depth and the width dimensions of driving wheel half arc nest eye 6, and described follower half arc nest eye 5 along the circumferential direction can be inserted in driving wheel half arc nest eye 6 inside cooperatively interacts, form overall adjustable nest ocular structure, driving wheel 1 along the circumferential direction arranges several semicircular arc endoporus 7, from described several semicircular arc endoporus 7 one end, between adjacent semicircular arc endoporus 7, spacing reduces successively gradually, on follower 2 along the circumferential direction and arrange several semicircular arc exit orifice 8 with semicircular arc endoporus 7 mated position place, between described several semicircular arc exit orifice 8 is adjacent, spacing is equal, described driving wheel 1 outer face is installed the spring bearer plate 3 with regulating alignment pin 4, described adjustment alignment pin 4 can be inserted in the circular hole of semicircular arc inner/outer hole 7,8 formation cooperatively interacted successively, completes lock in place along the circumferential direction between driving wheel 1 and follower 2.

When operation uses, epicycle entirety be fitted in seeder housing, feed shaft is inserted in epicycle centre bore, and feed shaft and driving wheel 1 are fixedly mounted with.The feed shaft rotated drives epicycle entirety to rotate in seeder housing through driving wheel 1, complete seed to by active and passive take turns the adjustable nest intraocular of entirety that half arc nest eye 6,5 forms fill kind of an operation.For adapt to different size maize seed grain need carry out overall adjustable nest eye size adjustment time, to alignment pin 4 be regulated from the semicircular arc of the original position cooperatively interacted by spring bearer plate 3, exit orifice 7, extract in 8, on driving wheel 1, circumference rotates follower 2, regulate and change the circumferential degree of depth of follower half arc nest eye 5 insertion overlapping in driving wheel half arc nest eye 6, realize the change of overall adjustable nest eye size dimension, then adjustment alignment pin 4 is inserted into by the semicircular arc of mutual correspondence position, exit orifice 7, in 8, to lead, follower 1, 2 circumferential lock in place, complete adjustment.
