Abstract

The utility model discloses a seed discharging tongue which is used on a seed discharging box of a seeder. The side end of the ligule of the seed discharging tongue is provided with a small gap, which solves the problems of big crushing rate, non uniform seeding, difficult control of the quantity of the seed, seed waste, etc., of the seeder when seeding the corn. The utility model can be used to match seed discharging box of the existing seeder, when seeding, the seed tongue only needs to replace, but other structures of the seeder have need not change.

Description

Seed-discharging tongue

The utility model is a kind of seed cup gate, and it belongs to employed kind of tongue of seeds discharging box on a kind of agricultural seeding machine.

The seed cup gate structure of existing sower seeds discharging box is seen accompanying drawing 1, it has tongue screw shaft tube, location cotter way, cotter way plate and ligule, its user mode is seen accompanying drawing 2, under the state of sower operate as normal, plant seed in the box because the weight of self and moving to the bottom, be distributed in seed wheel 1 around, along with advancing of sower, drive seed wheel 1 and rotate, the seed distributing groove 2 on the seed wheel 1 is transferred to seed cup gate 4 with seed 3, broadcasts uniformly by the kind pipe of kind of box bottom.But, if particle diameters such as sowing corn are greater than the kind period of the day from 11 p.m. to 1 a.m of the seed distributing groove degree of depth, be easy to seed is stuck in kind of wheel and plant to form between the tongue and stop up, make under the seed and broadcast minimizing, in case because when planting the pressure that wheel and the pressure of planting between the tongue can bear greater than seed, seed will be crushed and discharge by force, stops up the moment of eliminating, because the discharge that seed is squeezed and can super quantity, it is excessive to form partial seeding density.In the moment that many seeds are discharged suddenly, and the seed on top can not add to suddenly around the seed wheel, seed wheel idle running phenomenon occurs, and it is less to form partial seeding so again.If adjust distance between seed cup gates and the seed wheel by alignment pin 5, when making it above-mentioned phenomenon can not occur, the seed discharge rate again can be excessive, makes seed wheel out of hand.Therefore, use the bulky grain kind period of the day from 11 p.m. to 1 a.m such as existing planting with sowing machine corn, tend to occur uneven sowing and the bigger phenomenon of percentage of damage.

The purpose of this utility model is to provide a kind of seed cup gate, this seed cup gate can with the supporting use of the seeds discharging box of existing sower, above-mentioned existing in prior technology weak point can not appear at the bulky grain kind period of the day from 11 p.m. to 1 a.m such as sowing corn etc.

Technical solution of the present utility model is, the employed seed cup gate of a kind of sower seeds discharging box has tongue screw shaft tube, location cotter way, cotter way plate and ligule, and its special character is that the side of described ligule has a breach.

The size of breach is relevant with particle diameter and the thickness of sowing of using seed on the ligule, and particle diameter, density are big more, and then notch depth, width are big more.Generally can determine the breach size at last according to the actual production test, for the sowing corn, be 10mm to adopt the degree of depth, and width is that the breach of 13mm is better.

Accompanying drawing drawing of the present utility model is described as follows:

Fig. 1 is the structure chart of existing seed cup gate;

Fig. 2 is the existing user mode figure of seed cup gate on the sower seeds discharging box;

Fig. 3 is the structure chart of an embodiment of the utility model.

In conjunction with Fig. 3 being described as follows to present embodiment:

This embodiment is a sowing employed seed cup gate during corn, and it has tongue screw shaft tube 6, location cotter way 7, and cotter way plate 8 and ligule 9 have a dark 10mm, the small gap 10 of wide 13mm at the side of ligule 9.

From above narration as can be seen, because the utility model has a small gap on side, thereby at bulky grain kind period of the day from 11 p.m. to 1 a.m such as sowing corns, seed will slowly be discharged from breach, make sower remain on normal operating conditions always, can not occur that percentage of damage is excessive, uneven sowing or the excessive and out of contior phenomenon of kind amount, can save corn seed about about 25%; Because the utility model has just increased a small gap on the basis of existing seed cup gate, do not change any structure of sead feeder, only need change seed cup gate during sowing and get final product, thereby cost of manufacture seldom, and is simple and easy to do.

Claims

1, employed seed cup gate on a kind of sower seeds discharging box has the tongue screw shaft tube, and location cotter way, cotter way plate and ligule is characterized in that: have a breach on the side of described ligule.

2, employed seed cup gate on the sower seeds discharging box according to claim 1 is characterized in that: described breach is the breach of a degree of depth 10mm, width 13mm.
