Abstract

The utility model discloses a precision seeder, belonging to the technical field of the agricultural machine. The utility model is composed of an opening share, a depth wheel, a driving wheel, a seed box, a seeder, a ridged sweep, and a pressing wheel. The seeder is coaxial with the driving wheel, and a machine frame is provided with a bearing which can delay the open of the switch of the seeding opening. When the protrusion of the connecting rod of the seed box is contacted with the pivot of the seeder in a frictional way, the switch is opened gradually, and the seeder can be supplied with the seed. In the utility model, the bearing is utilized to regulate the opening position of the switch of the seeder, and therefore, the accuracy of the seeding spacing is improved, the precision of the seeding is ensured, the fine seed is not broken, and the quality of the fine seeding is enhanced. The utility model is also suitable for seeding the seeds of various crops.

Description

Seeder for depositing quantities of seed

The utility model relates to a kind of precision sower, belongs to agricultural mechanical field.

Existing sower kind is more, and seeding method can broadcast sowing, drilling or bunch planting, and roller seeding formula is arranged, and can only broadcast the solids seed; Turnover plate type is arranged, but can not be quantitative; Grooved pulley type is arranged, do not have accuracy; Also have the spring on-demand, accuracy is not high, and easy damaged seed.

The purpose of this utility model is to make the sowing position consistent relatively, reduces the breakage of seed, improves seeding quality.

The technical solution of the utility model is: wheeled seeder is coaxial with driving wheel, a uniform 4--8 sowing opening on the seeder, the switch of mouth is equipped with a bearing by coupled protector control on frame, can postpone opening the time of sowing opening switch when bearing and protector CONTACT WITH FRICTION.

Advantage of the present utility model and good effect are:

1. utilize bearing can regulate the open position of seeder switch, thereby guaranteed spacing in the rows, improved the accuracy of seed spacing;

2. this machine can guarantee to sow smart amount, and don't damaged breeding, has improved the Precision Seeding quality.

3. dependable performance is ditched, sows, earths up, is suppressed and once finish, and operating efficiency improves greatly, and everyone per hour can broadcast 0.7 mu of peanut, 0.9 mu of corn, 0.9 mu of soya bean, 1 mu in black soya bean, 1.5 mu of Chinese sorghums, 1.5 mu in millet, 1.5 mu of sesames, 1.5 mu of Chinese cabbages.

Describe structure of the present utility model in detail below in conjunction with drawings and Examples.

Fig. 1 is a structural representation of the present utility model.Among the figure, the 1st, plough, the 2nd, bail, the 3rd, gauge wheel, the 4th, seed-box, the 5th, frame, the 6th, seed guiding groove, the 7th, driving wheel, the 8th, bearing, the 9th, seeder, the 10th, standby ring, the 11st, earthing blade, the 12nd, press wheel.

Fig. 2 is a schematic top plan view of the present utility model.Among the figure, the 1st, plough, the 2nd, bail, the 3rd, gauge wheel, the 4th, seed-box, the 5th, frame, the 6th, seed guiding groove, the 7th, driving wheel, the 8th, bearing, the 9th, seeder, the 10th, standby ring, the 11st, earthing blade, the 12nd, press wheel, the 15th, seed-box switch protector, the 16th, the fulcrum on the seeder, the 19th, seed-box switch connecting rod.

Fig. 3 is a seeder operation principle schematic diagram.Among the figure, the 8th, bearing, the 9th, seeder, the 13rd, seeder switch protector, the 14th, seeder switch.

Fig. 4 is a seed-box operation principle schematic diagram.Among the figure, the 4th, seed-box, the 15th, seed-box switch protector, the 16th, the fulcrum on the seeder, the 17th, projection, the 18th, seed-box switch, the 19th, seed-box switch connecting rod.

This precision sower comprises plough (1), gauge wheel (2), driving wheel (7), seed-box (4), seeder (9), earthing blade (11), press wheel (12).In Fig. 3, wheeled seeder (9) is coaxial with driving wheel (7), and seeder (9) is gone up a uniform 4--8 sowing opening, and the switch (14) of mouth is controlled by coupled protector (13), during no bearing, in semicircle ADC zone, seeder switch (14) is closed condition substantially, is the critical localisation of opening of seeder switch (14) when being located at the A point, rolling with seeder (9), protector (13) opens switch (14) because of action of gravity moves downward, and seed falls; In semicircle ABC zone, seeder switch (14) is substantially opens shape, is the critical localisation of closing of seeder switch (14) when being located at the C point, and with the rolling of seeder (9), protector (13) closes switch (14) because of action of gravity moves downward.This seeding method can not guarantee the spacing of seed owing to the unstable variation that produces critical localisation of machine center.Frame (5) goes up a bearing (8) is installed now, when making seeder switch (14) arrive the A point, bearing (8) and protector (13) CONTACT WITH FRICTION can postpone opening the time of sowing opening switch (14) like this, open when making the fixing point A ' of switch (14) more than critical localisation.Along with the rotation of driving wheel, seeder is always opened switch when A ' point, sow, and not damaged seed.Can guarantee that like this seed spacing equates, thereby improve the accuracy and the seeding quality of sowing.

In Fig. 4, the switch (18) of seed-box (4) is controlled by coupled protector (15), on the connecting rod (19) of switch (18) and protector (15), a projection (17) is arranged, when a fulcrum (16) CONTACT WITH FRICTION on projection (17) and the seeder (9), switch (18) is opened gradually, when it broke away from this fulcrum (16), by protector (15) action of gravity, switch (18) cut out automatically.So just guaranteed that seeder (9) rotates a week, seed-box (4) is just in time for planting once.
