Description

Anti-blocking device for seed and fertilizer discharge pipe and sliding opener using the device

technical field

The invention belongs to the technical field of agricultural machinery, and in particular relates to an anti-blocking device for seed and fertilizer discharge pipes and a sliding opener using the device.

Background technique

Sowing and fertilizing is an indispensable link in agricultural activities, and mechanized operations have significant advantages such as high efficiency and good quality, and mechanized sowing and fertilizing is becoming more and more common. But the sowing and fertilizing of crops such as existing wheat, corn, adopt the sliding type ditch opener device more, this class device mainly contains several forms such as hoe shovel formula, boot formula, sliding knife formula. Sliding openers often have the phenomenon that the soil blocks the seed or fertilizer outlet when the operating machinery falls to the ground, especially when the soil moisture content is high and the hydraulic system of the tractor is not good. Such problems. When the seed discharge port or the fertilizer discharge port is blocked, it cannot be found in time, resulting in missed sowing, affecting normal agricultural production, and conventional seeding or fertilizing machines increase the size of the field due to the inconvenience of operation. The invention designs an anti-blocking device based on a sliding opener for seed and fertilizer discharge pipes, which can not only avoid blockage, but also have a movable tongue with a torsion spring that can improve soil covering performance, improve operating performance, and increase operating efficiency .

Contents of the invention

In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide an anti-blocking device for seed and fertilizer pipes and a sliding opener using the device, which can not only avoid blockage, but also has a torsion spring device The active tongue can also improve soil covering performance, improve operation efficiency, facilitate operation and ensure operation quality.

In order to achieve the above object, the technical scheme adopted in the present invention is:

An anti-blocking device for seed and fertilizer discharge pipes, comprising a movable tongue 5 for blocking the mouth of the seed and fertilizer discharge pipe 7, a fixed frame 1 is arranged outside the seed and fertilizer discharge pipe 7, and the bottom of the fixed frame 1 has a The fixed frame lug 8, the movable tongue 5 is provided with a movable tongue lug 9, the fixed frame lug 8 and the movable tongue lug 9 are connected by a fixed pin 3, and the fixed pin 3 is covered with a torsion spring 4, the torsion spring One end of 4 acts on fixed frame 1, and the other end acts on movable tongue 5.

The mouth of the pipe 7 for seed and fertilizer discharge is an inclined pipe mouth whose inclined plane is opposite to the advancing direction of the seed discharge and fertilizer discharge. The arc is towards the advancing direction of seeding and fertilization.

The fixed frame 1 is fixed on the ditch opener, and the seed and fertilizer discharge pipe 7 accepts seeds or fertilizers.

Compared with the prior art, the present invention can significantly improve the working efficiency of the existing drill based on the sliding opener, and the active tongue in the non-working state closes the seed or fertilizer outlet to ensure that the seed or fertilizer applicator is working The soil will not block the seed discharge port or fertilizer discharge port during the process of falling into the ground; during normal operation, the movable tongue is opened under the action of the soil force; and the mechanical work does not need to be put down during the slow walking process, which reduces the machine tools. The length of travel in the non-working state in the land improves the efficiency of mechanical operation and the convenience of operation; due to the elastic force of the torsion spring on the active tongue, the active tongue has an elastic compaction effect on the covering soil, thereby improving the compactness of seeds and soil, which is beneficial Seed germination and emergence.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 1, the anti-blocking device of the seed and fertilizer discharge pipe of the present invention includes a movable tongue 5 for blocking the 7 nozzles of the seed and fertilizer discharge pipe, and a fixed frame 1 is arranged outside the 7 pipes of the seed and fertilizer discharge pipe , the bottom end of the fixed frame 1 has a fixed frame lug 8, and the movable tongue 5 is provided with a movable tongue lug 9, and the fixed frame lug 8 and the movable tongue lug 9 are connected by a fixed pin shaft 3, and the fixed pin shaft 3 is covered There is a torsion spring 4, one end of the torsion spring 4 acts on the fixed mount 1, and the other end acts on the movable tongue 5. When the device is installed on a sliding opener, the seed and fertilizer discharge pipe 7 is used to receive seeds or fertilizer, and the fixing frame 1 is fixed on the main body of the opener.

As shown in Figure 2, it is a schematic view of the non-working state of the anti-blocking device of the present invention, the fixed pin shaft 3 passes through the movable tongue lug 9 and the fixed frame lug 8, and a cotter pin 2 is installed at one end of the pin shaft 3 for locking the pin Axis 3. In the non-working state, under the elastic force of the torsion spring 4, the movable tongue 5 seals the mouth of the seed and fertilizer pipe 7 to prevent the soil from blocking the seed and fertilizer pipe 7 during the falling process of the operating machine, avoiding the operation machine. The process of slowly putting it down during walking improves the operation convenience and work efficiency.

As shown in Figure 3, in the working state, the ditch opener 6 completes the ditching work, because the mouth of the pipe for seeding and fertilizer discharge 7 is an inclined pipe mouth with an inclined plane opposite to the forward direction of the discharge of seeds and fertilizers, and the movable tongue 5 is opposite. One end where the movable tongue lug 9 is located is an arc surface, and the convex arc of the arc surface faces the advancing direction of seed and fertilizer discharge. Therefore, when the unit was advancing, the front end of the movable tongue 5 rotated backward under the action of the soil, and the mouth of the seed and fertilizer pipe 7 was opened to work normally. Due to the existence of the torsion spring 4, the movable tongue 5 makes a slight reciprocating jump and slide during work, which has the effect of elastically suppressing the covering soil of the seeds, improving its covering performance, and is conducive to the seeds absorbing water and nutrients in the soil, and sprouting seedlings .
