Description

Rice field fertilizer spreading prevention device {INTERCEPTION DEVICE OF FERTILIZER SPREADING}

The present invention is applied to the fertilizer spreader for spraying fertilizer by the power of agricultural work machines such as tractors or cultivators. In detail, one side or both sides of the fertilizer blocking plate is blocked as necessary to prevent the fertilizer from being sprayed into the rice paddy. It relates to a rice field fertilizer spray prevention device that can be.

The fertilizer spreader spreads the fertilizer flowing out of the fertilizer tank by spreading the fertilizer into the fertilizer spreading pan by power. The basic composition of the fertilizer spreader has been described by Korea Utility Publication No. 98-209812.

The fertilizer spraying direction is correlated with the rotational speed of the spreading pan and the outlet position of the fertilizer. By controlling the outlet position, the fertilizer spraying direction can be limited and the angle of inclination of the side plate constituting the fertilizer barrier plate can be limited. .

In the former case, as shown by Korean Utility Model Publication No. 98-59501, it is configured to adjust the spraying direction by rotating the cylindrical fixture at an angle, so that it is sprayed in a parabolic form at the position where the fertilizer is spilled. When the fertilizer spraying pan rotates clockwise, the spraying direction can be controlled by the principle of spraying to one side depending on the position hit with the spreading pan, but a separate cylindrical fixture and a second stirring screw are required inside the spraying pan. As a result, the configuration is complicated, and in particular, in the case of the hydraulic drive method, there is a problem such as high load and splitting of fertilizer in the cylindrical fixture, and the position of the fertilizer tank (hopper) is increased by the height of the cylindrical fixture. There was a problem of increasing driving instability due to the rise. As a result, it is difficult to limit the spreading direction at the land boundary, so some fertilizers still fly over the boundary. Since one or the side blocking plate is fixed, there is a problem of limiting the spraying efficiency in the open area or the center of the land by limiting the spreading range by the fixed side blocking plate, i.e., the side plate constituting the conventional fertilizer blocking plate. In the normal fertilizer spraying operation, the fertilizer is sprayed excessively to the side in consideration of the fertilizer spreader running interval, and the function to prevent the double spreading of the fertilizer can be applied to the normal fertilizer spraying work as it is. Side fertilizer spraying If you want to be if there was a problem that can not achieve the desired results.

In particular, when fertilizers are sprayed on the rice fields, weeds grow because of excessive nutrients supplied to the weeds growing on the rice fields. Therefore, farmers have a lot of difficulties in removing them. It is pointed out as a problem to be solved urgently because it causes waste of waste and damage of adjacent crops.

The present invention improves the composition of the side plate constituting the conventional fertilizer blocking plate to allow extreme restriction on the fertilizer spraying from the rice paddies or the land boundary to the side as needed, and excessive nutrition is supplied to the weeds growing on the rice paddies. In order to prevent the problem of promoting the growth of fertilizers and fertilizer spraying work in the land borders to prevent adjacent crops.

In addition, by presenting a fertilizer spray prevention device configured to control the fertilizer spraying to the side by a simple operation in the tractor's driver's seat, it was devised for the purpose of convenient for the farmers.
