Description

Elastic gap disc fertilizer applicator

Technical Field

The utility model relates to a fertilizer applicator, in particular to an elastic notch disc fertilizer applicator.

Background

The fertilizer applicator is one of the important working components of the seeding machine, and is generally arranged at the front part of a seed metering device of a seeding unit. Mainly comprises a bracket, a ditching disc and a fertilizer pipe. In the fertilizing process, the ditching disc can effectively cut stubbles and ditches, and the fertilizer pipe completes fertilizing. The ditching disc of the existing fertilizer applicator is a circular cutting edge disc, and the ditching disc is arranged on the bracket in a rolling manner and is profiled along with the seeding monomer, so that the ditching disc cannot be profiled independently. Therefore, the prior fertilizer applicator has the following defects: the ditching disc can not be profiled independently, the obstacle crossing function is poor, and the damage rate of the mechanism is increased; the round cutting edge disc has poor stubble cutting and ditching performance and is easy to stick soil, thereby affecting the operation effect.

Disclosure of Invention

The utility model aims at providing an elasticity breach disc fertilizer applicator that operating performance is better, the reliability is higher to the above-mentioned problem that exists.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model discloses an elastic gap disc fertilizer applicator, which comprises a support, a ditching disc and a fertilizer discharging pipe, wherein the ditching disc and the fertilizer discharging pipe are arranged on the support, the fertilizer discharging pipe also comprises a left support arm, a limiting spring, a rotating arm, a right support arm, a hinged bolt, a guide rod and a guide sleeve, the support is provided with the left support arm and the right support arm, the left support arm and the right support arm are parallel to enable the support to form a U-shaped fork shape, the left support arm is hinged with the front lower end of the right support arm to form the rotating arm, the ditching disc is a gap disc and is positioned at the side of the rotating arm, the ditching disc is arranged at the lower rear end of the rotating arm in a rolling manner, the guide sleeve is arranged at the upper part between the left support arm and the right support arm through the hinged bolt, the guide rod is hinged upwards on an ear seat at the lower rear end of the rotating arm, the guide rod passes through the guide sleeve in a sliding manner, the, the guide rod is sleeved with a limiting spring, the lower rear end of the rotating arm is fixedly provided with the fertilizer pipe, and the fertilizer pipe is attached to the inner side surface of the ditching disc along the vertical direction.

As the utility model discloses an optimal scheme, ditching disc medial surface front portion is equipped with the board of clearing earth, and this board of clearing earth is adorned admittedly the rear end under the swivel arm, this board of clearing earth is pressed to the oblique blade that inclines forward on the ditching disc medial surface.

After the technical scheme is adopted, the utility model provides an elasticity breach disc fertilizer distributor has beneficial effect is:

when the elastic notched disc fertilizer applicator works with the advancing of the seeder, the ditching disc is a notched disc and is positioned on the side of the rotating arm, and the ditching disc is arranged at the lower rear end of the rotating arm in a rolling manner, because the front lower ends of the left support arm and the right support arm are hinged with the rotating arm. In the operation process, the notched disc has strong capability of cutting stubbles and strong ditching performance. The guide rod is sleeved with the limiting spring, so that under the premise of ensuring the fertilizing depth, the guide rod has an upward elastic adjusting range of 3cm under the action of the limiting spring, the ditching disc has a certain obstacle crossing function along with the upward swing of the rotating arm, and the damage rate of the mechanism is reduced. Therefore, the effects of better workability and higher reliability are obtained.

FIG. 1 is a front view of the structure of the elastic notched disc fertilizer applicator of the present invention;

FIG. 2 is a side view of FIG. 1;

fig. 3 is a sectional view taken along line a-a of fig. 2.

In the figure: a left support arm 1; a limiting spring 2; a rotating arm 3; a ditching disc 4; a fertilizer discharging pipe 5; a soil cleaning plate 6; a right arm 7; a hinge bolt 8; a guide rod 9; a guide sleeve 10.

Detailed Description

The invention will be described in further detail with reference to the following drawings and detailed description:

as shown in figures 1, 2 and 3, the construction of the elastic notched disc fertilizer applicator of the present invention is schematically shown, comprising a support, a ditching disc 4 and a fertilizer pipe 5 arranged on the support, a left support arm 1, a limiting spring 2, a rotating arm 3, a right support arm 7, a hinge bolt 8, a guide rod 9 and a guide sleeve 10, wherein the support is provided with the left support arm 1 and the right support arm 7, the left support arm 1 and the right support arm 7 are parallel to make the support form a U-shaped fork shape, the left support arm 1 is hinged with the rotating arm 3 at the front lower end of the right support arm 7, the ditching disc 4 is a notched disc and is positioned at the side of the rotating arm 3, the ditching disc 4 is arranged at the lower rear end of the rotating arm 3 in a rolling manner, the guide sleeve 10 is arranged at the upper part between the left support arm 1 and the right support arm 7 through the hinge bolt 8, the guide rod 9 is hinged with the ear seat at the lower rear end of the rotating arm 3 upwards, the guide rod 9 penetrates through the guide sleeve 10 in a sliding mode, a limiting pin shaft is arranged at the top end of the guide rod 9, a check ring is arranged on the lower portion of the guide rod 9 and located between the check ring and the lower end of the guide sleeve 10, a limiting spring 2 is sleeved on the guide rod 9, the lower rear end of the rotating arm 3 is fixedly provided with the fertilizer pipe 5, and the fertilizer pipe 5 is attached to the inner side face of the ditching disc 4 in the vertical direction.
