Abstract

The utility model relates to a sowing mechanism of a seed dibbling machine, which comprises a seed box, a sowing plate, a sowing arm, a sowing spoon and a sowing pipe, and the innovation points are as follows: the sowing mechanism elastically stores energy through the cooperation of a torsion spring on the tail end of the sowing arm and a collision wheel right above the sowing plate and throws seeds in the sowing spoon by releasing the elastic potential energy; the seed throwing force is directly related to the elasticity of the torsion spring and is unrelated to the speed of a tractor; and the sowing precision is more uniform and more reliable. In addition, an arc-shaped seed guiding cover is arranged, so that the seeds enter the sowing pipe along an arc-shaped track, so as to prevent the seeds from being rebounded into the seed box; and therefore, the sowing mechanism of the seed dibbling machine is particularly applicable to dibbling machines for sowing soybean, rape and other crop seeds.

Description

A kind of sowing mechanism of seed dibbler

Technical field

The utility model relates to a kind of sowing mechanism of agricultural seeder machinery, particularly seed dibbler.

Background technology

Seed dibbler is to be the planting machinery of sowing object with the crop seed, and most popular a kind of seed sowing machine is and the south of the River 2BG-6A type rice wheat drilling machine of walking tractor matching that the market recoverable amount has reached the hundreds of thousands platform at present.Its shortcoming is: the control of seeding quantity cannot say for sure to demonstrate,prove accurate unanimity, and under the vibration of whole machinery, is prone to broadcast leakage and multicast phenomenon, and sowing quantity is big, can't adapt to the sowing of crops such as rape, soybean, peanut.

The inventor of the application the utility model patent also number of applying for a patent once is the utility model patent of ZL200820113920.4, it discloses a kind of seed dibbler, its sowing mechanism is a rotary throwing kind mechanism, this mechanism comprises seed-box, the seed tray of rotation, be installed in the lever on the seed tray, the throwing kind spoon on lever top, and the sowing pipe of seed tray one side.Throw kind of spoon under the seed tray effect of rotation, take out the seed in the seed-box uniformly, utilize the throwing kind spoon of rotation to retreat suddenly, make the seed of throwing in kind of the spoon be thrown into the sowing pipe with inertia.It is accurate that this device has seeding quantity, though solved broadcast leakage and multicast phenomenon, filled up the domestic blank of still not having desirable seed precise sower, but equally also have some shortcomings: the seed in its throwing kind of spoon utilizes effect of inertia to throw and send, and seed inertia size is relevant with the speed of service of tractor, seeding accuracy is still not ideal, still has some defectives.Very fast when tractor speed, when the inertia of seed was big, seed was easily got on the sowing pipe and is rebounded, and causes a spot of broadcast leakage.

The utility model content

The technical problems to be solved in the utility model provides a kind of sowing mechanism of seed dibbler, can accurately and reliably seed be thrown into and realize precisely sowing in the soil.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of seed dibbler sowing mechanism, comprise seed-box, the sowing axle, seed tray, the sowing arm, sowing spoon and sowing pipe, be provided with the sowing axle that links to each other with power section in the described seed-box, on the sowing axle several seed trays are housed, several sowing arms are housed on the seed tray, dismountable sowing spoon is equipped with on the top of sowing arm, end is connected with seed tray by axle sleeve, it is characterized in that: be with torsion spring on the described axle sleeve, be provided with directly over the seed tray one can be when it rotates moment block the wheel that bumps that the sowing spoon makes the accumulation of energy of torsion spring elasticity, an arc seed guide housing is set with sowing between the pipe bumping wheel.

The structure of described arcuate guide cover is: the top is an arc, closes up to oral area gradually from the top in both sides, the arcuate guide cover that the import large outlet is little.

Characteristics of the present utility model are: block the sowing spoon short time by bumping wheel, make that the torsion spring that is connected with the sowing arm can compress energy storage, when torsion spring discharged elastic potential energy, the sowing spoon of sowing arm end was gone into to sow as the impelling of shooting ball with seed and is managed.The impelling dynamics of seed is only relevant with the return elastic force of torsion spring, and irrelevant with the speed of a motor vehicle of tractor, seeding accuracy is more evenly reliable.Simultaneously, arc seed guide housing can make seed enter in the sowing pipe along arc track, prevents its seed-box that rebounded.Thereby the utility model is particularly suitable for using on the high planter of claimed accuracy.

Specifically buy the mode of executing

As shown in Figure 1, a kind of seed dibbler sowing mechanism comprises seed-box (4), sowing rotating shaft (1), seed tray (7), sowing arm (3), sowing spoon (5), torsion spring (2), bumps wheel (6), sowing pipe (9), arc seed guide housing (8).

Be provided with in the described seed-box (4) and can drive the seed tray (7) that rotates by sowing axle (1), be evenly distributed with four sowing arms (3) on the seed tray (7), the top of this sowing arm (3) is provided with dismountable bowl-shape sowing spoon (5), end is connected with seed tray (7) by axle sleeve, torsion spring (2) is enclosed within on the axle sleeve, and its two ends are connected with sowing arm (3) with seed tray (7) respectively.

When seed tray (7) rotated, the sowing spoon (5) of sowing arm (3) and end thereof rotated with seed tray (7), took a certain amount of seed during sowing spoon (5) process seed-box (4) below.Bump wheel (6) be located at seed tray (7) directly over, be used for the torsion spring (2) that is contained in sowing arm (3) is carried out accumulation of energy; Shown in Fig. 2,3,4, sowing spoon (5) and sowing arm (3) that seed is housed are moving in the rotation under the drive of seed tray (7), after being bumped wheel (6) and blocking, at the seed tray that is rotated further (7) and bump under the effect of wheel (6), sowing arm (3) and sowing spoon (5) sink gradually and rotate around axle sleeve, feasible torsion spring (2) the elastic deformation accumulation of energy that is enclosed within on the axle sleeve.When sowing spoon (5) sinks down into when bumping wheel (6) and can't block it, torsion spring (2) discharges elastic potential energy, promotes sowing spoonful (5) and launches out seed.After seed is gone out by impelling, enter in the sowing pipe (9) that is located at seed tray (7) one sides, realize sowing.

For the part seed direct collision that the prevents impelling seed-box that rebounds behind the sowing pipe (9), be connected with an arc seed guide housing (8) bumping between wheel (6) and the sowing pipe (9), shown in Fig. 5,6,7, this arc seed guide housing (8) center has arc guide groove one, after seed is sowed spoon (5) is dished out, enter in the arc guide groove, enter sowing pipe (9) along arc guide groove, and the cross-sectional width of this arc guide groove reduces gradually, helps the concentrated sowing pipe (9) that enters of sowing spoon (5) seed.
