Description

A seeder suitable for different sowing depths and spacings of rapeseed and wheat

technical field

The utility model relates to the field of mechanized seeding, in particular to a seeder suitable for different seeding depths and distances of rape and wheat.

Background technique

The seeder is a kind of planting machine that uses crop seeds as the sowing object. The existing rapeseed and wheat seeder is powered by a wheeled tractor and is mounted on a three-point suspension. It can sow 4 or 6 rows at a time, and a row uses a seed meter. , There are 4 rows of holes on the seed metering device, and the seeding rate can be adjusted within a certain range to meet different requirements of the seeding rate.

Wheat and rapeseed are two common crops, and they are also common crops that are sown by seeders, with a high degree of mechanization. Due to the different growth characteristics of rapeseed and wheat, the spacing requirements for the two are also different when sowing. In addition, rape needs to be sown shallowly, and wheat needs to be sown deeply. The depth requirements of the two are also different. At present, the seeding openings of general seeders are fixed, that is, the distance and depth are fixed, so that the same seeder cannot It can not only realize wheat sowing, but also can realize rape sowing, but can only choose different seeders or different specifications of seed discharge ports to realize the sowing of different seeds, so that the seeder has certain limitations and cannot meet the sowing requirements.

Utility model content

The purpose of this utility model is to provide a seeder suitable for different sowing depths and distances of rapeseed and wheat, and solve the problem that the seeding openings of the current seeders are relatively fixed, and the distance and depth of sowing cannot be adjusted, resulting in certain gaps in the seeder. Limitations, unable to adapt to diverse sowing conditions.

In order to achieve the above object, the utility model adopts the following technical solutions to realize:

A planter suitable for different sowing depths and spacings of rape and wheat, comprising a support platform, a seed output bin, rollers and a suspension platform, the rollers are arranged below the support platform, and the suspension platform and the support platform are connected by hinges;

The horizontal plate of the suspended platform is also provided with a strip plate and a seed discharge port, the strip plate is provided with a strip hole, and the seed discharge port is clamped on the strip hole by a bolt and a second nut, and the seed discharge port The mouth is communicated with the output port of the seed output bin through a flexible pipe.

In this solution, since the suspension platform and the support platform are hinged, the distance from the horizontal plate of the suspension platform to the ground can be adjusted through the screw and the first nut, that is, the distance from the seed discharge port to the ground can be adjusted, so that different Deep sowing; on the other hand, since the seeding port is fixed on the strip plate through bolts and second nuts, the spacing of the seeding ports can be adjusted through the adjustment of the bolts and nuts, thereby meeting the needs of different sowing spacings . The seed output bin in this solution is a functional part of the existing planter, and its specific structure will not be introduced too much here. It mainly realizes the time-sharing and orderly output of seeds, and then through the hose, Seed opening, into the ground.

Further, as a preferred solution, at least one bar is provided on the outer wall of the first nut, and the extension line of the bar passes through the center of the first nut. The retaining strip can further block the screw rod on the basis of the first nut.

Further, as a preferred solution, the first nut is provided with two retaining strips, and the extension lines of the two retaining strips coincide. By setting two opposite retaining bars, on the basis of clamping the screw rod, it is also convenient to rotate the first nut, which is convenient to better adjust the distance from the seeding port to the ground, so as to achieve more accurate sowing and meet all requirements. required sowing requirements.

Further, as a preferred solution, the lower part of the seed discharge opening is plow-shaped. The plow shape is an existing structural form. The seed opening in this scheme can be understood as a shape in which the lower part of a cylinder is cut obliquely. This structure is conducive to inserting the lower part of the seed opening into the soil , while not affecting normal sowing, especially suitable for wheat that needs deep sowing.

Further, as a preferred solution, scales are provided on the strip plate. Through the scale, the distance between the seed discharge openings can be adjusted more accurately, so as to obtain better seeding effect.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

(1) The utility model is provided with a suspension platform, and the suspension platform is hinged with the support platform, and the distance between the seed discharge port and the ground is adjusted through the screw rod and the first nut, so that it can meet the requirements of different sowing depths.

(2) In this utility model, the seed discharge port is set on the strip plate, and a strip hole is set on the strip plate, and the seed discharge port is fixed on the strip plate through bolts and second nuts, so that the seed discharge is realized. The arbitrary spacing adjustment of the mouth can meet the sowing spacing requirements of different crops.

(3) The utility model has a reasonable structural design and simple operation, and can realize the adjustment of the spacing and depth of the seed outlets on one seeder, thereby meeting the sowing requirements of different crops and improving the adaptability of the seeder.
