Hereinafter, a mower will be described with reference to the accompanying drawings.

1 and 2, the mower of the present invention is largely composed of a main body 100, an upright guide portion 200, a cut portion 300, and a height adjusting portion 400.

<Body>

1 and 2, the main body 100 according to the present invention has a power transmission shaft 110. The power transmission shaft 110 is a member that receives power from a traveling device (not shown) such as a tractor.

The gear box 120 is installed on the power transmission shaft 110. The gear box 120 is connected to the traveling device and serves to change the transmission direction of power in a direction perpendicular to the received power or rotational force. Therefore, power from the traveling device may be transmitted to the side of the main body 110 through the power transmission shaft 110.

Therefore, the upright guide portion 200, the cut portion 300, and the height adjusting portion 400 described below are connected to the power transmission shaft 110 through a power transmission member (not shown) such as a chain to transmit power. Power may be transmitted from the shaft 110.

<Upright guidance department>

1 and 2, the upright guide portion 200 according to the present invention has a rotation shaft 210 whose both ends are rotatably supported by the main body 100, and a predetermined length extends radially from the outer circumference of the rotation shaft 210. And upright members 220 and 230 having a plurality of ribs 222 and 232 along the extending direction.

2 and 4, the upright members 220 and 230 are made of an elastic member such as rubber having a predetermined elasticity.

The upright members 220 and 230 are symmetrical to each other from the ends of the first and second fixing plates 221 and 231 which are installed along the rotation shaft 210 along the opposite directions, and the ends of each of the first and second fixing plates 221 and 231. The first and second ribs 222 and 232 extend to be inclined at an angle to form the same. Here, the first and second ribs 222 and 232 are interlocked at the time of rotation of the rotating shaft, and when the ground crops exposed to the ground are collapsed, the first and second ribs 222 and 232 are scraped up along the rotating direction.

Here, the first and second fixing plates 221 and 231 of the elastic material may be bolted to the outer circumference of the rotating shaft 210, or may be coupled in a rail coupling manner.

In addition, the upright members 220 and 230 according to the present invention may be composed of the first and second upright members 220 and 230. The ground 1 of the ground 1 and the ground 3 of the underground crop 2 described below will be referred to FIGS. 8A to 8C.

That is, the first upright member 220 is installed at one end and the second upright member 230 is installed at the other end with the center of the rotation shaft 210 as a boundary. Here, the first and second upright members 220 and 230 may have the same configuration.

Here, as shown in FIG. 4, the first ribs 222 and the second ribs 232 are arranged side by side along the longitudinal direction of the rotation shaft 210. The first ribs 222 are formed to be inclined outward at a predetermined inclination with respect to a central portion along the longitudinal direction of the rotation shaft 210. In addition, the second ribs 232 are also formed so as to spread outward from the center portion along the longitudinal direction of the rotation shaft 210.

Here, the first ribs 222 and the second ribs 232 are formed in a shape that is spaced apart from each other at the center of the rotation axis 210 boundary.

Therefore, the net 3 exposed to the ground 1 corresponding to the first area is established through the first ribs 222 of the first upstanding member 220, and immediately the second of the second upright member 230 is formed. The nets 3 exposed to the ground 1 of the second area located on the side of the first area are formed through the ribs 232, and the nets 3 formed in the first and second areas are entangled with each other. It can also be prevented.

Here, since the first and second ribs 222 and 232 are formed to be symmetrical with each other, when the upright is guided between the first and second ribs 222 and 232, the rotations are guided, the time when the upright is guided is It can be increased for a certain time, so that the order of the underground crops can be guided stably upright.

In addition, the first and second ribs 222 and 232 extending from the first and second fixing plates 221 and 231 of the upright members 220 and 230 are symmetrical with respect to the axis of rotation 210, which is an upright member ( When the 220 and 230 are rotated, the ribs 222 and 232 of one side inclined downward are first scraped up against the nets 3 of the ground 1, and then the slopes of the other inclined ribs 222 'and 232' are erected ( 3) It serves to guide you to keep upright. That is, the upright members 220 and 230 according to the present invention may guide to maintain the upright state after cutting up the net 3 and standing up until it is cut.

Meanwhile, the first and second ribs 222 and 232 may be integrally formed at the ends of the fixing plates 221 and 231 to protrude, or may be detachably installed.
