Description

A no-till seeder

technical field

The invention relates to a seeder, in particular to a no-tillage seeder, and belongs to the field of agricultural technology.

Background technique

The no-tillage seeder is an agricultural machine that crushes the previous crops and returns them to the field and sows at the same time. As far as the applicant knows, when the previous no-tillage planter has different straw crops in the field (such as cotton straw, corn straw, wheat straw, etc.), the operation process of crushing the previous straw and returning it to the field and sowing the next crop The following problems are encountered: 1) Due to the different heights of stubble residues and ridge heights of the straw itself in the field, and the unevenness of the field ground, it is necessary to constantly adjust the height of the machine so that the crushing device and the field ground can maintain a suitable distance before the residue 2) Because the root stubble (root system) of different crops grows at different depths in the ground and has different resistance to crushing, it is difficult to have wide adaptability. For example, crops with hard root stubble and good flexibility are often difficult 3) Since the height adjustment of the crushing tool is realized by adjusting the height of the depth-limiting device (see item 1 in Figure 1), this adjustment is cumbersome and time-consuming, which seriously affects productivity.

The Chinese patent with the application number 201410113918.7 discloses a no-tillage wheat planter with full straw coverage. Although the ratio of the amount of straw returned to the field and the amount of coverage can be changed, it fails to solve the above problems.

Contents of the invention

The purpose of the present invention is to provide a no-tillage planter that can save time and conveniently adjust the height from the ground according to the condition of the previous crops through structural improvement.

In order to achieve the above object, the basic technical solution of the no-tillage planter of the present invention is: comprising a walking frame equipped with a seeding device, the walking frame is equipped with a horizontal axis rotating crushing device, and the roller shaft of the crushing device contains at least one set of The outer ends arranged at intervals in the axial direction protrude radially from the pulverizer, and the pulverizer and the roller shaft form a radial movement pair. The roller shaft is equipped with a control shaft connected to the inner end of the pulverizer. The output shaft drive connection of the motor.

When working, the no-tillage seeder of the present invention can change the radial extension length of the pulverizer at any time by remote control according to the residual height of the stubble, the height of the ridge, the ground undulation, or the depth of the stubble, and the ability to resist crushing, so as to adjust Compared with adjusting the height of the crushing knife by adjusting the depth-limiting device, the distance from the ground or the depth of entry into the soil is quicker and more convenient, significantly improves productivity, and is more conducive to ensuring the crushing effect and seeding quality, creating good conditions for the later growth of crops.

Further, the front and rear ends of the traveling frame are respectively supported on the depth-gauge wheel and the earth-covering suppression wheel.

Furthermore, the walking frame is equipped with a rotating crushing device, a rear throwing device, a fertilizing device and a seeding device from front to back.

Still further, the hollow roller shaft of the crushing device contains two sets of crushing knives that are radially opposite and axially displaced.

Still further, the crushing knife forms a radial movement pair through its mounting bracket and the roller shaft, and the outer end is Y-shaped.

Still further, the control shaft is equipped with pinion gears that are respectively connected to the racks at the inner ends of the mounting frames of the pulverizing knives.

Detailed ways

Embodiment one

The no-tillage planter of the present embodiment is shown in Figures 1 and 2, the front and rear ends of the traveling frame 8 are respectively supported on the depth-limiting wheels 1 and a group of soil-covering and pressing wheels 7 on both sides. The walking frame 8 is equipped with a horizontal axis rotating crushing device 5, a rear throwing device 2, a fertilizing device 4 and a seeding device 3 from front to back.

The concrete structure of crushing device 5 is as shown in Figure 3, 4, and its horizontal hollow roller shaft 5-11 contains two groups of axially spaced outer ends radially protruding out crushing knives 5-2, two groups of crushing knives 5-2 Radially opposite and axially misaligned. Each crushing knife 5-2 constitutes a radial movement pair by its mounting frame 5-3 and the roller shaft, and the outer end is Y-shaped. One end of the hollow roller shaft 5-11 is fixedly connected with the belt pulley 5-1 driven by the power source, and the other end is fixedly connected with the sealing plate 5-5. The inside of the roller shaft 5-11 is equipped with two pulleys respectively driven by the remote control motor 5-8. Regulating shaft 5-4, the controlled terminal of remote control motor 5-8 is connected to the control output terminal of wireless remote control circuit 5-9, and is powered by built-in battery 5-10. The pinion 5-7 that is respectively connected with each pulverizing knife mounting frame 5-3 inner end tooth rack drive is housed on the control shaft 5-4. The wireless remote control circuit 5-9 is located in the middle of the remote control motor 5-8 and the battery power supply.

The rear throwing device 2 is made up of a blower fan positioned at one side of the transverse conveying device 6 and a rear throwing air duct. The lower ends of the fertilizing device 3 and the seeding device 4 respectively lead out a fertilizer discharge pipe and a seed discharge pipe. These devices are similar to the prior art, so they will not be described in detail.

During operation, the no-till seeder of the present embodiment is towed and advanced. Its wireless remote control circuit can accept the remote control signal from the operator's hand-held remote control, so as to control the forward or reverse rotation of the remote control motor, drive the rack of the mounting frame through the pinion, and drive the crushing knife to radially expand and contract as needed, thereby adjusting the operation process. The diameter of the hitting circle can be adjusted at any time according to the residual height of crop stubble, ridge height, ground undulation, or root stubble depth and anti-crushing ability, and the distance from the ground or the depth of the crushing knife can be quickly adjusted at any time, which greatly improves the quality of straw and its root stubble. The crushing effect makes the crushing more uniform and thorough, and then it is transported by the horizontal conveying device to the rear throwing device on one side and thrown by the wind, followed by fertilization, sowing, and soil covering, which provides a guarantee for the good growth of crops in the later stage.
