Description

seed drill

technical field

The utility model relates to the technical field of mechanical equipment, in particular to a seed drill.

Background technique

When the seed drill is in operation, the walking wheel drives the seeding wheel to rotate, and the seeds are discharged from the seed cup in the seed box into the seeding pipe according to the required seeding rate, and fall into the opened groove through the opener, and then are covered with soil. The compacting device covers and compacts the seeds. After emergence, the crops form parallel and equidistant rows. The drills used for different crops use different types of seed meters and openers, but their structures are basically the same. Generally, they consist of a frame, traction or suspension devices, seed boxes, It is composed of seed metering device, transmission device, seed delivery pipe, ditch opener, track marker, walking wheel and soil suppression device. Among them, the main factors that affect the quality of sowing are the seed metering device and the ditch opener. The commonly used seed metering devices include grooved wheel type, centrifugal type, and disc type, and the ditch openers include shovel type, shoe type, sliding knife type, and single circle type. Disc type and double disc type and other types.

However, existing seed drills have some disadvantages during use. When the seed drill is transporting grain, it is easy to cause damage to the grain, so that the growth effect of the grain sown into the ground is not good.

Utility model content

The purpose of this utility model is in order to solve the shortcoming that exists in the prior art, and proposes the drill.

In order to achieve the above object, the utility model adopts the following technical scheme: the seed drill includes a conveying bin and a material distribution plate, a rotating shaft is welded at the middle position of the material distribution plate, and multiple A distribution bin, and a filling block is arranged between two distribution bins, a limit ring is arranged on the outside of the distribution tray, and a discharge pipe is opened at the middle of the bottom of the limit ring, and the limit ring is The middle position of the top of the circular ring is connected with the hemispherical storage bin through the feeding pipe, and the top of the hemispherical storage bin is welded with a delivery bin, and the inner middle position of the delivery bin is provided with a fixed shaft, and Helical blades are welded, and the top of the delivery bin is connected with the fixed card through the second telescopic spring.

As a further description of the above technical solution:

The hemispherical storage bin is a soft cloth stretchable structure.

As a further description of the above technical solution:

Symmetrical fixing plates are welded on both sides of the limiting ring, and fixing bolt holes are opened at the ports of the fixing plate.

As a further description of the above technical solution:

Both sides of the bottom of the delivery bin are connected to the limiting ring through the first telescopic spring.

As a further description of the above technical solution:

There are two second telescopic springs in total, and the two second telescopic springs are symmetrical about the vertical centerline of the fixing card.

In the utility model, firstly, the conveying chamber of the drill is provided with spiral blades, so that the grains to be sown can enter the hemispherical storage chamber in an orderly manner, and telescopic springs are arranged on the bottom and the top of the conveying chamber. During the operation of the seeder, there will be a certain amount of shaking, which will drive the conveying bin to vibrate, so that the grain inside the conveying bin will not be blocked. There is also a limit ring on the outside of the material pan, and a discharge pipe is provided at the bottom of the limit ring. For the grains falling from the hemispherical storage bin, the amount can be confirmed in the distribution bin and then transported to the discharge pipe. position, for post-operation, since the grain falls directly into the distribution bin, it can avoid the phenomenon of bumping and damage to the grain, so that the growth effect of the grain sown into the ground will not be affected.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example.

Referring to Fig. 1-3, the seed drill includes a conveying bin 2 and a distribution tray 9, the middle position of the distribution tray 9 is welded with a rotating shaft 91, and a plurality of distribution bins 92 are equidistantly provided on the distribution tray 9, and Filling blocks 93 are arranged between the distribution bins 92, and the limit ring 10 is arranged on the outside of the distribution tray 9, and the bottom middle position of the limit ring 10 is provided with a discharge pipe 11, and the limit ring 10 The middle position of the top of the storage bin 3 is connected with the hemispherical storage bin 3 through the feeding pipe 4, the top of the hemispherical storage bin 3 is welded with the delivery bin 2, the inner middle position of the delivery bin 2 is provided with a fixed shaft 1, and the fixed shaft 1 is The spiral blade 5 is welded, and the top of the delivery bin 2 is connected with the fixed card 13 through the second telescopic spring 12 .

The hemispherical storage bin 3 is a soft cloth retractable structure, and the two sides of the limit ring 10 are welded with symmetrical fixed plates 7, and the ports of the fixed plate 7 are provided with fixing bolt holes 8, and the two sides of the bottom of the delivery bin 2 The first telescopic spring 6 is connected to the limiting ring 10 , and there are two second telescopic springs 12 , and the two second telescopic springs 12 are symmetrical about the vertical centerline of the fixing card 13 .
