Description

Stubble breaking ditch and ditch edge loosening device for rice stubble no-tillage seeder

technical field

The utility model relates to a seeder auxiliary device, in particular to a device for breaking stubble and ditching and ditch edge loosening for a rice stubble no-tillage seeder, belonging to the technical field of seeder auxiliary devices.

Background technique

Rice stubble no-tillage sowing wheat does not damage the soil structure, is conducive to soil moisture conservation, and can save investment in machine tillage, which is a better planting method.

However, in the prior art, after the rice is harvested, there will be straw on the ground, and the ditch opener of the planter will hang grass and block up during the advancement process; The back cover soil is unreliable (especially the soil fluidity on both sides of the ditch is poor, and the cover soil suppression wheel cannot reliably push the soil on both sides into the ditch), resulting in the inability to close the seed ditch, and the seeds are exposed and cannot be covered by the soil, resulting in a decrease in the emergence rate. affect the quality of sowing.

Contents of the invention

The utility model takes the following technical solutions:

A device for breaking stubble and ditching and ditch edge loosening for a rice stubble no-tillage planter, characterized in that: the device for breaking stubble and ditching and ditch edge loosening is provided with stubble breaking components sequentially on the same line from front to back 3, ditch opener 2, ditch edge loosening part 1; described stubble breaking assembly 3 comprises breaking stubble disc part 301, and described disc part 301 has sharp blade, can cut seam to land when rotating, and will Surface straw and weeds are cut off; the ditch opener 2 is used for ditching along the kerf; the ditch edge loosening part 1 includes a pair of top-to-bottom inwardly inclined, with the stubble-breaking disc part 301 as the The ditch edge loosening disc part 101 which is symmetrical on both sides of the center corresponds to the position of the ditch edge soil and cuts the ditch edge soil when rotating.

Further, the bottom of the ditch loosening disk part 101 is higher than the bottom of the stubble breaking disk part 301 .

Further, the angle between the ditch loosening disc part 101 and the stubble breaking disc part 301 is 30°.

Further, the distance between the bottom of the disk part 101 and the stubble breaking disk part 301 is 10 cm.

Further, the stubble breaking assembly 3, the ditch opener 2, and the ditch edge loosening component 1 are all fixed on the main structure of the rice stubble no-tillage seeder.

The beneficial effects of the utility model are:

1) The stubble breaking component cuts the soil, and at the same time cuts off the hanging grass of the opener of the seeder in the process of advancing, so as to facilitate ditching.

2) The ditch loosening part cleverly cuts the ditch soil after ditching, which separates the ditch soil from the soil next to it, which is convenient for soil covering when covering the soil, is conducive to the closure of the ditch, and prevents the seeds from being exposed , so as to increase the emergence rate and improve the quality of sowing.

3) The lower side of the disc can cut into the sides of the trench opened by the opener, and cut a part of the soil on the side of the ditch, which also plays a role in loosening the soil, so that the subsequent soil covering and suppression parts can push the soil on the side of the ditch into the ditch Inside, thus ensuring the reliability of the covering soil.

4) Due to the high moisture content, heavy soil viscosity and poor fluidity of the rice stubble soil, the utility model is especially suitable for use in the rice stubble soil, which greatly improves the soil fluidity on both sides of the ditch, and facilitates the soil pressing wheel to reliably push the soil on both sides to the In the ditch, for clay-heavy soil, it has unexpected technical effects.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

Referring to Fig. 1-Fig. 6, a device for breaking stubble and ditching and ditch edge loosening for a rice stubble no-tillage planter is characterized in that the device for breaking stubble and ditching and ditch edge loosening is in the same straight line from front to back The stubble breaking assembly 3, the ditch opener 2, and the ditch loosening part 1 are arranged in sequence on the top; the stubble breaking assembly 3 includes a stubble breaking disc part 301, and the disc part 301 has a sharp blade, which can Cut the land, and cut off the straw and weeds on the surface; the ditch opener 2 is used for ditching along the cut; The stubble breaking disc part 301 is a ditch edge loosening disc part 101 symmetrical on both sides of the center, and the ditch edge loosening disc part 101 corresponds to the position of the ditch soil, and cuts the ditch soil when rotating.

Referring to FIG. 2 , the bottom of the ditch loosening disc part 101 is higher than the bottom of the stubble breaking disc part 301 .

Referring to Fig. 2, the included angle between the ditch loosening disc part 101 and the stubble breaking disc part 301 is 30°.

Referring to FIG. 2 , the distance between the bottom of the disc member 101 and the stubble breaking disc member 301 is 10 cm.

The stubble breaking assembly 3, the ditch opener 2 and the ditch edge loosening part 1 are all fixed on the main structure of the rice stubble no-tillage seeder.

The broken stubble disc part 301 is perpendicular to the ground, cuts a slit on the ground, cuts off the surface straw and weeds, and prevents the straw and weeds from hanging on the ditch opener at the rear. Ditch edge loosening disk part 101 is arranged by two sets of disks similar to the stubble-breaking disk part but the size of the stubble-breaking disk part is small. On both sides of the ditch, cutting a part of the ditch soil also plays a role in loosening the soil, which is convenient for the subsequent soil covering and suppression parts to push the ditch soil into the ditch, thereby ensuring the reliability of the covering soil.

The main feature of the utility model is that the cooperation of the front stubble breaking disc and the rear two ditch edge loosening discs arranged obliquely can better ensure the passability of the implement and the quality of the operation.
