BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pulling-type weeding apparatus and apparatus, and more particularly, to a weeding apparatus which can be attached to a weeding apparatus and effectively remove weeds, and a weeding apparatus including the same.

Generally, the rice weeding system of rice is mostly using the non - powered method of weed control by weed suppression burial and soil disturbance by germination and growth inhibition. Therefore, not only the herbicidal efficiency is low but also many repetitive tasks are required. To reduce this, a power-driven weed method is required.

The conventional power-driven weeding method is a cutting method by high-speed rotation of a weed blade and a power requirement is large, and a power-driven weeding apparatus having a fixed blade (Patent Document 10-1424062) At level 3, the work still requires several hundred watts of power.

Such conventional lawn mowers use a high output power source such as an internal combustion engine and thus are difficult to be lightened.

In addition, in the case of a small robot developed in accordance with the agriculture automation trend of a small-sized farmland, there is a problem that a low-output low-speed mechanism must be implemented as a high-efficiency low-cost power source for effectively using the robot in a place where power limitation is high.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a herbicide apparatus and a herbaceous herbaceous plant which are light in weight and can remove weeds effectively by traction.

A weed cutting mechanism according to one embodiment of the present invention for solving this problem comprises a support base, a weed blade connected to a lower end of the support base and cutting the root of the weed by the pulling force of the pulling apparatus, A rotating roller installed on both sides of the support so as to be disposed on the support so as to transfer and discharge the weed cut by the weeding blade while disturbing the surface of the soil, A power transmitting portion for transmitting the generated power to the rotating roller, and a mounting bracket connected to the upper end of the support for connection with the towing device.

The support may include a joint for protecting the weed mechanism from an excessive traction load.

The support may include a lower support to which the weeding blade and the rotary roller are coupled, an upper support to be coupled with the mounting bracket, and a spring bar to jointly connect the lower support and the upper support.

The power transmission unit may include a speed reducer that reduces the power output from the motor to a constant speed and transmits the reduced power to the rotating roller.

The herbicide device may further comprise a sensor for recognizing the curvature of the soil surface to keep the depth of the herbicide blade constant from the soil surface.

The weed cutting apparatus according to one embodiment of the present invention includes a support base, a weed blade connected to a lower end of the support base and cutting the root of the weed by the pulling force of the drawer, A rotating roller installed on both sides of the support so as to transfer and discharge the weed cut by the weeding blade while disturbing the soil surface while disturbing the surface of the soil, a motor installed inside the support to generate power, And a mounting bracket connected to the upper end of the support for connection with the towing device, a tool bar coupled with the mounting bracket, and a tool bar coupled to the tool bar, And a towing device for towing the herbicide.

The pulling-type herbicidal apparatus and apparatus according to the present invention can minimize the power required for weeding by utilizing the prime pulling power of the towing vehicle for the weeding, thereby simplifying the structure of the weeding apparatus.

In addition, it can be effectively applied to places where there is a lot of power limitation like a mobile robot by realizing the high power and high speed rotation power weeding work effect required for weeding, with low output and low speed.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a perspective view schematically showing a traction sheared weeding apparatus according to an embodiment of the present invention. Fig. 2 is a view showing the principle of the traction sheared weaving apparatus of the present invention.

Referring to Figs. 1 and 2, a tow-cut weeding apparatus according to an exemplary embodiment of the present invention includes a weeding apparatus 100, a tool bar 200, and a towing apparatus (not shown). The weeding operation by the weeding apparatus 100, the tool bar 200 coupled to the weeding apparatus, and the traction apparatus connected to the tool bar 200 and pulling the weeding apparatus 100, The herbicide 100 is pulled in the running direction of the traction sheared weeding apparatus.

Hereinafter, with reference to FIG. 3 and FIG. 4, the structure of the traction herbicidal apparatus and the herbicidal method will be described in detail.

Fig. 3 is a perspective view showing the pull-cut weed apparatus of Fig. 1; Fig. Fig. 4 is a view showing the inside of the traction sheared weed apparatus of Fig. 3; Fig.

3, the weeding apparatus 100 includes a support 110, a herbicide 120 connected to a lower end of the support 110 and cutting the roots of the weed by a traction force of the traction device, A rotary roller 130 provided on both sides of the support 110 to be disposed on the upper part of the blade and for transferring the roots of the cut weed to the rear by crushing and disturbing the surface of the soil, A power transmission unit 142 for transmitting the power to the rotation roller 130 and a mounting bracket 150 for connection with the towing device (not shown).

The herbicide 120 is connected to the ground surface of the support 110 in parallel so that the herbicide 120 is positioned perpendicular to the roots of the weed as the traction sheared herbicide advances forward Lt; / RTI > The herbicide 120 is pulled to a depth of about 2 to 3 cm from the surface of the soil so that the root of the weed that is located in the soil is cut. In addition, as the herbicide 120 is pulled at a depth of about 2 to 3 cm from the surface of the soil, the herbicide 120 separates not only the roots of the weeds but also the soil around the roots, And is raised to the top of the herbicide 120 along with the weeds whose roots have been cut.

The rotary roller 130 is installed on both sides of the support 110 so as to be disposed on the upper side of the weed blade 120. The rotation roller 130 may be supported on the support 110 by a rotation roller fixing bracket 118 extending from the support 110 to fix the rotation roller. Since the rotating roller 130 is disposed on the upper part of the weed cutting blade 120, a portion of the weed that has been roots cut by the weeding blade 120 and a part of the top soil separated from the soil, And is positioned between the rotating rollers 130. At this time, when the power generated by the motor 140 is received and rotated by the rotating roller 130, the weed that is roots between the rotating roller 130 and the support 110, A part thereof is crushed and disturbed by the rotating roller 130, and is transported and discharged rearward.

The motor 140, which generates power transmitted to the rotating roller 130, is installed inside the support 110. The motor 140 is connected to the power transmission unit 142 connected to the lower portion of the motor 140 and connected to the rotation roller 130 in both lateral directions of the power transmission unit 142.

The power transmitting portion 142 includes projections 142a on both sides. The protrusions 142a pass through both sides of the supporter 110 and pass through the surface where the rotation rollers 130 are in contact with the supporter 110. [ The protrusions 142a passing through both sides of the supporter 110 and the surface where the supporter is in contact with the supporter are firmly fixed to the supporter 130 by the supporter bearing 132. Therefore, the rotation of the rotation roller 130 fixed to the protrusion 142a of the power transmission unit 142 is transmitted to the power transmission unit 142 and is received by the motor 140 to rotate. For example, the motor 140 may be a motor driven at a rated power of 12.7 W at 6000 rpm, and the power transmitting portion 142 may be a 100: 1 speed reducer.

Referring to FIGS. 1 and 3, the mounting bracket 150 is formed at the upper end of the support 110 to connect the towing device and the weeding apparatus 100. The mounting bracket 150 couples the weighing apparatus 100 and the tool bar 200 together. Although not shown in FIG. 1, the tool bar 200 connected to the weeding apparatus 100 is connected to the towing apparatus (not shown) so that a surplus pulling force that the tow-cut weeding apparatus travels to the weeding apparatus 100 .

For example, the traction device may include a linear guide (not shown), and the tool bar 200 may be coupled to the traction device in association with the linear guide. The linear guide is a unit for adjusting the height of the weeding apparatus 100 coupled to the tool bar 200. The height of the weighing apparatus 100 can be adjusted by moving the tool bar up and down.

The weeding apparatus 100 may include a sensor (not shown) to recognize the curvature of the soil surface to maintain the depth of the weed blade 120 constant from the soil surface. As the traction sheared weeding apparatus is driven by the traction sheared type weeding apparatus, the weeding apparatus 100 is pulled in the traveling direction of the traction transfer type weeding apparatus to cut roots of the weed, It is necessary to adjust the position of the herbicide 120 of the herbicide 100, since the herbicidal process for transferring and discharging the herbicide is performed. Accordingly, if the sensor recognizes the curvature of the soil surface, the traction device calculates the required height of the herbicide blade 120 of the herbicide device 100 based on the recognized shape of the surface curvature of the soil surface, Can be moved in a vertical direction along the linear guide to automatically control the height of the weeding apparatus 100.

For example, the towing device (not shown) may be a traveling robot equipped with an autonomous traveling system, and the traveling robot autonomously travels to the height of the light weight weed apparatus 100 connected to the tool bar 200 Can be automatically controlled and towed for weeding.

In addition, the support 110 includes a joint to protect the weed 100 from an excessive traction load that the towing device (not shown) can pull by pulling the weeding device 100.

For example, the support 110 includes a lower support 112 coupled to the weed blade 120 and the rotary roller 130, an upper support 114 coupled to the mounting bracket 150, And a spring bar 116 connecting the upper support 114 and the upper support 112 in a joint structure. The configuration of the joint part is such that when the weeding apparatus 100 is advanced by the towing apparatus (not shown) in the running direction of the pull-cutting weeding apparatus, the lower part of the support table 110, that is, Even if the herbicide 120 pulled at a depth of 2 to 3 cm is subjected to a force in the backward direction of the traveling direction, the lower support is flexibly pushed rearward in the advancing direction by the spring bar 116, The support 100 and the support 100 can be prevented from being damaged. In an embodiment of the present invention, the lower support 112, the upper support 114, the lower support 112 and the upper support 114 are connected to the spring bar 116 by the joint part of the support 110, The lower support 112 and the upper support 114 may be connected to each other by a coupling other than the spring bar 116 or another joint may be formed to protect the weeding apparatus 100 .

Such a traction shearing type weeding apparatus reduces the power required for the reciprocating motion and the rotating motion of the cutting edge in the conventional power type weeding apparatus to 1/3 level. The structure of the motor 140 and the power transmitting portion 142 that transmit power to the rotating roller 130 is simplified and lightened. Also, since the weed cut by the weeding blade 120 by the pulling force is crushed and disturbed by the rotating roller 130 together with the soil topsoil, re-emergence of the weed is greatly reduced, and the efficiency of the weeding is increased by 80% or more.

While the present invention has been described in connection with what is presently considered to be practical and exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention. Accordingly, the foregoing description and drawings are to be regarded in an illustrative rather than a restrictive sense of the invention.
