Description

Disk shaft dislocation type fertilizer application furrow opener

Technical Field

The utility model belongs to the technical field of agricultural machinery, in particular to a disk shaft dislocation type fertilizing furrower applied to a grain seeder.

Background

The double-disc type fertilizing and ditching device is generally arranged on a grain drill and a intertillage crop seeder and is mainly used for digging fertilizing ditches meeting the agricultural requirements on the field surface. The commonly used double-disc type fertilizer application furrow opener is characterized in that a pair of discs are symmetrically arranged left and right according to a certain wedge angle, the edge of each disc is a smooth and complete circular cutting edge, and the discs are arranged on a main beam of a seeder through a support arm. The support arm of the double-disc type fertilization furrow opener is divided into a rigid support arm, an elastic support arm and a rigid and elastic combined support arm, and the installation height of the support arm can be adjusted to meet the requirements of different fertilization depths. Compared with a scraper type and boot shoe type fertilizing furrow opener, the technical scheme improves the obstacle crossing capability and partially solves the problem of dragging and piling of straws and stubble. But still has the shortcoming that smooth edge's two disc type fertilization furrow openers skid rate is high, and when the straw stubble is more or the soil block is stopped up between two discs in the field piece, the disc can lose to rotate, skid, and then causes to drag the heap and block up.

Disclosure of Invention

The utility model aims at providing a disk shaft dislocation formula fertilization furrow opener that does not lose the commentaries on classics, do not press from both sides soil, hinder the ability reinforce more, the ditching resistance is little to the above-mentioned problem that exists.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model discloses a dish axle dislocation formula fertilization furrow opener, including the inner support, adorn the back at this inner support and lead fertile pipe admittedly, and the mud scraper, the disc, the breach dish, the mount pad, still including setting up the elasticity handle between this inner support and this mount pad, the vice handle of elasticity, stagger around the asymmetric goat's horn shape of both sides one-tenth on this inner support and set up two dish axles that have positive and negative thread, this disc, the breach dish sets up on the dish of this inner support both sides is epaxial respectively with rolling, and fasten through positive and negative nut, make this breach dish and this disc form the front and back configuration, and toe becomes the wedge angle in the front.

As the preferred design scheme of the utility model, the elastic handle is designed into the shape of a plate-type hoe bow, the short end of the lower part of the elastic handle is fixedly arranged at the top end of the inner support through the short end fastening bolt of the elastic handle, and the long end backing of the upper part of the elastic handle is fixedly arranged in the handle trousers of the mounting seat through the long end fastening bolt of the elastic handle behind the auxiliary handle.

After the technical scheme is adopted, the utility model provides a dish axle dislocation formula fertilization ditching utensil has beneficial effect is:

1. no loss and rotation and no soil clamping. The edge of the notch disc is uniformly provided with cutter teeth formed by notches, and when the notch disc is contacted with soil, the cutter teeth roll and cut into the soil, so that the notch disc does not lose rotation; and because the mounting shaft of the notch disc and the mounting shaft of the circular disc are staggered front and back, the two discs move relatively when in rolling cutting ditching, so that soil blocks cannot be clamped between the two discs.

2. The obstacle crossing capability is strong. When the front notch disc and the rear disc are in shaft dislocation type fertilization ditcher for operation, the elastic handle can generate elastic deformation when encountering obstacles such as stones, and the like, thereby avoiding rigid scraping with the obstacles and improving the obstacle crossing capability.

3. The ditching resistance is small. The long end of the arc-shaped elastic handle of the hoe is backed with the elastic auxiliary handle and then is fixedly arranged in the handle trousers of the mounting seat and is clamped on the main beam of the seeder through the mounting seat; the short end of the lower part of the bow-shaped elastic handle of the hoe is fixedly arranged on the inner support, and the notch disc and the disc are arranged on the disc shafts on the two sides of the inner support in a rolling manner, so that during operation, under the pushing of a main beam of the seeder, the notch disc and the disc successively cut into soil and perform rolling cutting ditching in the soil, and along with the continuous change of soil resistance, the notch disc and the disc at the short end of the lower part of the elastic handle vibrate at high frequency, so that the soil entering capacity of the notch disc and the disc is improved, and the ditching resistance is reduced.

Drawings

FIG. 1 is a front view of the structure of the disk shaft dislocation type fertilizer boot of the present invention;

FIG. 2 is a top view of FIG. 1;

fig. 3 is a sectional view taken along line a-a of fig. 1.

In the figure: an inner support 1; a fertilizer guide pipe 2; a mud scraper 3; a disc 4; a notch disc 5; the short end of the elastic handle tightly fixes the bolt 6; an elastic handle 7; an elastic auxiliary handle 8; the long end of the elastic handle is tightly provided with a bolt 9; a mounting seat 10.

Detailed Description

The invention will be described in further detail with reference to the following drawings and detailed description:

as shown in fig. 1, fig. 2 and fig. 3, the structure schematic diagram of the disk shaft dislocation type fertilizing furrower of the present invention is provided, which comprises an inner support 1, a fertilizer guiding pipe 2 fixedly installed at the back of the inner support 1, a mud scraper 3, a disk 4, a gap disk 5, a mounting seat 10, an elastic handle 7 and an elastic auxiliary handle 8 arranged between the inner support 1 and the mounting seat 10, two disk shafts with positive and negative threads are staggered from front to back on the inner support 1 in an asymmetric claw shape, the disk 4 and the gap disk 5 are respectively arranged on the disk shafts at two sides of the inner support 1 in a rolling manner, and are fastened by positive and negative fastening nuts, so that the gap disk 5 and the disk 4 are configured from front to back, and the front beam forms a claw angle.

As the preferred design scheme of the utility model, the elastic handle 7 is designed into the shape of a plate-type hoe bow, the short end of the lower part is fixedly arranged at the top end of the inner support 1 through the short end fastening bolt 6 of the elastic handle, the long end backing of the upper part is fixedly arranged in the handle trousers of the mounting seat 10 through the long end fastening bolt 9 of the elastic handle after the auxiliary handle 8.

The utility model discloses a theory of operation is: when the fertilizer drill is used, the disc shaft dislocation type fertilizer furrow opener is clamped on a main beam of a seeder through the mounting seat 10 and is arranged in front of a seeding unit, and the notch disc 5 and the disc 4 are firstly and secondly cut into soil and perform hobbing and furrowing in the soil under the pushing of the main beam of the seeder along with the advancing of a seeding unit. Because the edge of the notch disc 5 is evenly provided with the cutter teeth formed by the notches, and the notch disc 5 and the circular disc 4 respectively roll forwards around two disc shafts which are staggered forwards and backwards. Therefore, the straw and the stubbles remained on the ground surface can be easily ground without losing and rotating or clamping soil. And because the notch disc and the disc at the short end of the lower part of the elastic handle generate high-frequency vibration along with the continuous change of the soil resistance, the soil-entering capacity of the notch disc and the disc is improved, and the ditching resistance is reduced. The depth of the fertilizing ditch can be adjusted by changing the installation height of the inclined installation section of the elastic handle 7 in the trousers of the handle of the installation base 10 according to the operation requirement.

The utility model is suitable for an install and use on grain seeder.
