Crop fertilizer applying device

Abstract

The invention discloses a crop fertilizer applying device, and belongs to the field of agricultural machinery. The crop fertilizer applying device comprises a main box body. The bottom of the main boxbody is connected with walking wheels. A feed port is formed in the top of the main box body. A discharge pipe is connected with the bottom of the main box body. A switch valve is arranged on the discharge pipe. A quantity control box located below the switch valve is connected with the discharge pipe. An inner cavity of a cylindrical structure is arranged in the quantity control box. A rotatingshaft coaxial with the inner cavity is arranged in the inner cavity. At least four clamping grooves which are indented inwards are formed in the circumference of the surface of the rotating shaft at equal intervals. Sector-shaped plates are inserted in the clamping grooves. Small-arc ends of the sector-shaped plates are attached to the surface of the rotating shaft. Large-arc ends of the sector-shaped plates are attached to the side wall of the inner cavity. All the sector-shaped plates just fulfill the space between the rotating shaft and the side wall of the inner cavity. Intermittent discharging can be realized, and fertilizers can be easily saved; the amount of fertilizers discharged at a time and the time interval of two adjacent times of discharging can be regulated and controlled, and the crop fertilizer applying device can be suitable for moderately applying fertilizers to different crops and is high in application value.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a crop fertilizing device. Background technique [0002] When the soil cannot provide the nutrients needed for the growth and development of crops, it is necessary to fertilize the crops to supplement their nutrients. However, rational fertilization can give full play to the effect of fertilizer on increasing production, which is an important measure to achieve high yield, stable yield and low cost, while unreasonable fertilization will lead to reduced yield, and even result in burnt seedlings and plant wilting. [0003] At present, the existing technology has realized the mechanized operation of fertilization operations. The device generally includes a box for containing fertilizers. Fertilization, but the feeding process of the fertilizer is continuous, and there is a gap between every two adjacent crops, which increases the amount of fertilizer, which is not conducive to...

However, rational fertilization can give full play to the effect of fertilizer on increasing production, and is an important measure to achieve high yield, stable yield and low cost, while unreasonable fertilization will lead to reduced yield, and even result in burnt seedlings, plant wilting and other consequences

[0003] At present, the existing technology has realized the mechanized operation of fertilization operations. The device generally includes a box for containing fertilizers. Fertilization, but the feeding process of the fertilizer is continuous, and there is a gap between every two adjacent crops, which increases the amount of fertilizer, which is not conducive to saving costs

Relevant technical personnel can easily think that intermittent feeding can be realized by frequently opening and closing the switching valve on the feeding pipe. The switching valve is easily damaged, and the amount of feeding and the intermittent time between two adjacent feedings cannot be adjusted
