Interrow and interplant weeding device for paddy field seedling

Abstract

The invention discloses an interrow and interplant weeding device for paddy field seedlings, which comprises: a box body connecting plate arranged on a rack; a main transmission box and a suspension rack arranged on the box body connecting plate; a power transmission shaft is connected with the main transmission box; the rack at one side of the box body connecting plate is sequentially provided with a weeding depth adjusting rod, a spring wire transmission rod a and an eccentric wheel transmission box; a spring wire transmission rod b, a clutch and a transmission swing rod are sequentially connected with the rack on the other side of the box body connecting plate through bearings; a cover plate is fixed on the other side of the rack; a seedling separator and a weeding cage transmission shaft are arranged on the lower side of the cover plate, and a weeding cage and a single-tooth weeding cage are distributed on the weeding cage transmission shaft. According to the interrow and interplant weeding device for the paddy field seedlings, the interrow and interplant weeding can be carried out simultaneously, thereby improving the efficiency of mechanical weeding, loosening the root systemsoil of the seedlings, improving the production and the quality of the seedlings, and being environment-friendly and pollution-free.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to an inter-row weeding device for rice seedlings in a paddy field. Background technique [0002] my country is a large agricultural country with a large population and a large food consumption country. Rice production plays an important role in my country's food production. More than 60% of the country's population takes rice as a staple food. The rice planting area in my country is about 30 million hectares. It accounts for 40% of the country's grain planting area and 28.2% of the world's rice planting area. However, weeds in paddy fields compete with rice for growth space, fertilizer nutrients, light, water, heat and other resources, affecting the growth and development of rice, resulting in rice output and The quality is reduced, and the loss rate of rice yield caused by weed damage is more than 15% every year. Therefore, in the production process of rice, scientifi...

Problems solved by technology

[0004] In the process of rice growth, the excessive use of herbicides not only reduces the quality of rice, but also pollutes the soil and water sources and damages the ecological environment. Due to the high labor intensity and low weeding efficiency of manual weeding, mechanical weeding is regarded as "green rice" in the planting process The best weeding method, using mechanical weeding instead of chemical weeding, the work efficiency is 5 times higher than that of manual operation, mechanical intertillage weeding loosens the soil for the growth and development of seedling roots, avoiding the use of chemical herbicides to cause the soil to be ineffective Looseness, the disadvantage of curbing the extension of the root system, and promoting the growth of seedlings. However, the development of weeding machinery in rice tillage is still blank in our country. , South Korea and most areas of our country adopt wide row cultivation. The research on weeding technology between rows is still in its infancy in China. Most existing weeders in the market can only remove weeds between rows, but cannot achieve the ideal effect on weeds between rows. Weeding effect, therefore, the weeding machine of present stage production can only carry out single weeding operation generally, and paddy field weeding machine of the present invention can carry out weeding between row, also can carry out weeding between row simultaneously, can satisfy agronomic requirement, is of great importance to China's green agriculture development is of great significance
