Abstract

The present invention relates to a plow which is connected to a tractor to plow farmland. More specifically, the present invention relates to a 12-bottom plow which is advantageous for forming furrows and a manufacturing method thereof. The plow comprises: a base frame having pipes connected in a grid pattern; a rotor forming a rotation axis when the base frame is rotated using hydraulic pressure; a rotating hydraulic cylinder rotating the rotor using the hydraulic pressure; a bracket installed on the base frame; and plow bottom portions each installed above and below the bracket. In addition, a 6-plow bottom portion is installed at an upper part and a 6-plow bottom portion is installed at a lower part, wherein the plow bottom portion installed at the upper part and the plow bottom portion installed at the lower part based on the base frame are installed in a mirror-reversed manner. When a tractor turns, the base frame rotates to bring down the plow bottom portion at the upper part installed in an opposite direction of the plow bottom portion at the lower part used when moving forward. Accordingly, soil is turned in the same direction as a soil turning direction when moving forward. Therefore, furrows can be formed smoothly by adjusting an entry angle of the plow bottom portion depending on the soil condition.

Description

12 plows favorable for forming ridges and furrows}

The present invention relates to a plow that plows cultivated land by connecting it to a tractor, and more particularly, unlike conventional plows in which back soil has to be reversed only to one side when plowing a field, the tractor is installed symmetrically so that the reverse direction of the back soil is opposite to each other. 12-row plow and its manufacture, in which ridges are formed with 3 pairs of plows, and when the tractor turns, the plows are rotated to reverse the soil in one direction with the plows installed in one direction downward, forming the ridges. It's about how.

In general, in Korea, a method of cultivating a field by towing a multi-plow with a tractor has been mainly used.

As these tractor plows move forward while being towed by the tractor, cultivated fields such as paddy fields, fields, or greenhouses are plowed by the plowshares and crests, and the soil guided by the crests is reversed to one side according to the twist direction of the crests and loaded so that the ridges will be achieved

However, this type of plow had to be operated several times because it was difficult to evenly crush the already hardened soil, the fertilizer was not properly mixed, and it did not accurately form furrows.

In order to solve the above problems, Korean Registered Utility Publication No. 20-0414989 has been proposed as a prior art.

Unlike conventional multiple plows, the prior art presented the effect of continuously forming accurate furrows and increasing work efficiency according to one operation.

However, the prior art did not solve the problem of not crushing the soil evenly, and in order to solve this problem, the domestic market began to introduce plows having developed characteristics for tillage. Unlike conventional plows, it has high traction resistance, but it has excellent deep hardness, reversibility, and safety.

However, since the general plow reverses the backsoil only to one side, if the backsoil is reversed to the right when moving forward, when the tractor turns, it is reversed to the left based on the forward direction, forming an unbalanced and inaccurate ridge, which is disadvantageous for plant growth and drainage.

Therefore, a method of lifting the plow, moving the tractor backward, and then lowering the plow and repeating the operation was used, and this method of ridge formation work was performed only when the tractor was traveling in either direction before or after the farmland. Plowing the arable land takes a lot of overall work time, and when the plow simply drives without plowing the arable land, it is difficult to move the tractor after lifting the plow.

Therefore, in order to form the ridges in a balanced way, the plow is rotated when the tractor turns, and the plow installed in the opposite direction of the plow used when moving forward is turned down to reverse the plow in the same direction as the reversing direction when moving forward. necessity emerged.
