Description

[0001] The present invention relates to a mowing machine having improved weeding performance,

The present invention relates to a method for controlling weeds by using a plurality of herbicide blades rotated in the horizontal direction, thereby securing a high performance of weaving a wide area at a time, improving the durability of parts by reducing the occurrence of load, To prevent the occurrence of safety accidents caused by the accident.

Generally, a mowing device is a device for cutting crops (such as grains, grasses, grasses, etc.). Various kinds of mowing devices have been proposed and widely used according to the use purpose and the form.

In the past, as a means of cutting grass, we used to work with a sickle, called a sickle, to work, so it took a lot of work, it takes too long to work, the work efficiency is low, , Or frequent human accidents such as fingers being cut off.

Then, as the science developed, the mechanization of the agricultural machinery was realized. Typically, a working machine type lawn mower attached to an agricultural machine called a cultivator or a manager was developed and used.

However, as a result of having a lot of power and complicated structure in adhering lawn mowers to a cultivator or a manager, the utility value is reduced and the use is avoided, so that a weed-type weed system equipped with an engine capable of specializing in weeding work has been developed It is widely used.

Due to aging of the labor force structure that can naturally farm in the rural areas and aging of the rural population as the day progresses, the existence of agriculture is worsening due to the avoidance of agriculture by the aged and elderly people. It is true.

As mentioned above, the mechanization of agriculture is further accelerated in accordance with the aging trend of the rural population, and the farming method is also being developed, and the farming method is being transformed from the past culinary form farming to the large-scale farming. Recently, there has been developed a riding type grass mower that can carry out a weeding operation while a person is riding and driving, and it has a lot of grass in a short time It was possible to cut.

As a prior art related to such a mower, " Patent Registration No. 1066663, name / lawnmower, is proposed.

In the prior art, the cutter is refracted by the multi-step joint so that when the cutter collides with an object such as a rock, it is refracted at a plurality of joints to mitigate the impact, thereby reducing damage to the cutter.

However, in the conventional all other mowers including the above-mentioned prior art, when the grass is collapsed forward by the grass mower housing at the time of traveling and the grass falling in the inside of the grass mower housing comes in, the weed operation is performed by the cutter, A large amount of load is applied to the power generating means such as a motor for driving the motor, resulting in a serious noise generation and a significant reduction in the herbicidal performance.

Moreover, the grass that falls forward may result in the grass falling further ahead before the herbicide is formed, and the herbicidal performance of the herbicidal composition is further reduced.

In addition, since the cutter performs the weeding with a hitting force such as a hammer, when the stake is struck, fragments are splashed to cause safety accidents, as well as cause breakage of the cutter and frequently replace the cutter. Additional cost is required.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to solve the problems inherent in the conventional lawn mowers by using a plurality of herbicidal blades rotated in the horizontal direction before the lawn mowing machine So that the grass in the standing state can be cut off and the weeding performance can be greatly improved.

In addition, the herbicide of the present invention can eliminate the gap between the herbicide blades by eliminating the gap between the herbicidal herbs by overlapping the adjacent herbicidal blades with each other, thereby improving the efficiency of the herbicidal action. We will do it.

According to the present invention, it is possible to greatly improve the herbicidal performance by cutting a grass in a standing state by a plurality of herbicidal blades rotating in the horizontal direction before the grass is pushed down by the grass mower housing, and the plurality of herbicide blades Can be efficiently weeded.

In addition, the present invention improves durability of parts by reducing the burden of the weeding motors and weed blades by weeding the grass in the standing position at the front of the grass mower housing while preventing the grass falling inside the grass mower housing from coming in. It provides a noise-reducing effect.

In addition, since the plurality of herbicide blades are overlapped with the other herbicide blades adjacent to each other, the gaps between the herbicidal blades are eliminated, thereby eliminating blind spots during weeding, thereby improving the quality of the herbaceous plant. Thereby improving the efficiency of the system.
