Description

MULTI FURROW WEEDER

The present invention relates to a multi-type mower.

Weeds grow naturally in the rice fields and field groves that have been planted or transplanted. Because weed absorbs the nutrients around it with its vigorous growth power, it prevents the growth of the crops, so weeding for the farmers considering the yield has become important agriculture in the year.

It is not easy for a person to remove the weeds of the rice field and the furrow in the agricultural railroad which lacks one hand. The herbicide, which has been used for a long time as a quick and easy herbicide, contributed to the increase of human food. On the other hand, extensive use of herbicides can lead to serious side effects such as soil contamination, destruction of surrounding ecosystems, and heavy metal poisoning due to residual pesticides. Moreover, resistant weeds are promoting the overuse of herbicides, and super weeds, which do not die by several times the amount they have used in the past, have also created a threat to the ecosystem.

Chungyeong mower is an agricultural machine that directly removes or cuts off weeds between rice paddies and furrows during the growth of crops. It is designed to replace people 's direct use of basketball. Chungyeong mackerel has been attracting attention as a herbicide method to overcome the dysfunctions and limitations of herbicides because it feeds air to the soil while cutting and transferring the soil with the cutting of weeds.

A working machine for chiken weeding is a cultivator that is driven by power by a sweeper or a rotary hoe attached to a tractor that can be used for passenger cars, (Walking mode) in which a user carries a walking cart with a power device for driving a mowing blade by operating a user while the user is walking while mounting a mowing blade on a walking platform. Chungyeong mowers that have a sowing date have the function of cutting, so they can also function as a crop harvesting machine.

Chongqing mowers are operated in various work environments such as sloped fields and narrow troughs, so the convenience of operation is the key. In particular, the chikyong mowers, which are used in rice fields with water, also have a high resistance to water and can easily fall off. By rotating the mowing day, water or cut weeds are scattered around the crops or inconvenience to the workers. Therefore, there is a need for an apparatus that can easily operate and operate the elderly person or the worker such as a woman even in a poor working condition. Nevertheless, rice fields and fields often contain many furrows, so weeding in a single foliage will inevitably reduce the efficiency of the herbaceous herb.

Rotary type chongqing mowers are constructed to be able to carry out various weeds at the same time, which is widely used in agriculture. However, it has a disadvantage that the power required is excessive and the abrasion rate of the blade is high. In addition, the rotary type is difficult to use for other purposes than rice paddy, and after the middle period of growth after the transplanting, the grass is liable to be wrapped around the axis of the rotary blade during the herbicidal operation, thereby lowering the herbicidal efficiency.
