Description

Harrow for farming

The present invention relates to an agricultural harrow, and more particularly, to improve the bearing capacity of the two auxiliary blades of the harrow body, as well as to increase the adhesion of the harrow body to the ground, and to mitigate the impact of collision with the surrounding objects. It's about an agricultural harrow.

In general, harrows are farm equipment that evens the land and have been used on cows or horses.

7 and 8 show the 'farm harrow' (hereinafter, referred to as a conventional design) of the patent application No. 99-13175 filed by the present applicant, the configuration thereof is as follows, the present invention is an improved design thereof.

As shown in the related art, the conventional agricultural harrow includes a harrow body 100 mounted to the rear of the tractor; Auxiliary blade (101) which is pulled out or drawn while sliding to both sides of the harrow body (100); A drive motor 102 installed vertically on an upper side of the harrow body 100 and generating a driving force by power supply; The pinion 104 is installed on the rotation shaft 103 of the drive motor 102 so as to slide the auxiliary blade 101 by the driving force of the drive motor 102, and the pinion 104 is disposed on both sides of the pinion 104. A power transmission unit 105 formed by engaging a pair of racks 106 connected to the auxiliary blades 101 to face each other; The pinion 104 of the power transmission part 105 and the housing part 107 which protects the exterior of the rack 106 are comprised.

The agricultural harrow configured as described above is capable of drawing out or drawing out both side auxiliary blades 101 of the harrow body 100 by operating the drive motor 102 formed at the center of the harrow body 100. The driving force of the drive motor 102 is engaged with the pinion 104 and the pinion 104 installed on the rotation shaft of the drive motor 102 and the end side is transmitted through the rack 106 connected to the auxiliary blade 101.

The following describes the use and operation of the subject innovation constructed as above.

First, the auxiliary blade 2 of the present invention receives the driving force by the operation of the drive motor 11 as in the conventional harrow to the rack and pinion to be drawn out or drawn in both sides of the harrow body 1, wherein the auxiliary The blade 2 slides on the outer surface of the harrow body 1, that is, on the front portion of the harrow body 1 with respect to the traveling direction, and thus, on the inner surface of the harrow body 1, i. It is possible to improve the bearing capacity than the slide in the rear part of 1).

In addition, it is possible to adjust the angle of the harrow body (1) by adjusting the chain (6a) (6b) of the angle adjuster 5, in more detail, in the state in which the rear chain (6b) is fixed When the front chain 6a is pulled or released, the front angle of the harrow body 1 is adjusted up and down about the hinge axis h on the shock absorber 43 side.

When the rear chain 6b is pulled or released while the front chain 6b is fixed, the rear angle of the harrow body 1 rotates up and down about the hinge axis h, and the harrow according to the height of the ground. The position of the main body 1 can be adjusted, wherein the harrow body 1 is pressurized from the upper side to the lower side by the spring 433 elastic force of the shock absorber 43 vertically installed at the center of the harrow body 1. Will be able to bring the earth closer to the ground.

On the other hand, when the harrow body 1 is backward and collides with the surrounding object on the rear side, the harrow body 1 is slidably coupled to the support tube 442 of the slide unit 44 with the collision and the harrow body By reversing with the slide bar 441 coupled to (1) it is possible to mitigate the impact due to the collision.

And when harrowing, the water coming from the soil is not only drained through a plurality of drain holes 21 formed in the harrow body (1) is to be able to reduce the resistance of the soil generated during the serenity work by partially discharged together.

As described above, the present invention reinforces the supporting force of the auxiliary blades mounted on both sides of the harrow body, and configures the harrow body to be left, right or reversed when colliding with the surrounding object, thereby easily bending the auxiliary blade. It will have the effect of preventing the loss, damage and breakage in advance.

In addition, by allowing the harrow body to be adjusted up and down with respect to the ground, the harrow body is pressurized from the upper side to the lower side by the elastic force of the spring to improve the adhesion with the ground, thereby making the ground more even. Therefore, no separate work is required, and thus the efficiency and simplicity of the work can be achieved.

And by forming a plurality of drain holes in the harrow body can significantly reduce the resistance to the soil in the progress direction during the work and the water coming from the soil, thereby pulling the harrow body with less force more easily to work It will have an effect.
