Plant Protection Fertilizer Sprayer

Abstract

The invention discloses a plant-protection fertilizer spray machine's fertilizer spray pipe, which comprises a fertilizer spray pipe and fertilizer spray nozzles. The lower pipe wall of the fertilizer spray pipe is provided with several fertilizer spray nozzles. The fertilizer spray nozzle is an integrated sleeve-shaped member with a turn-ups flange, and comprises a flange and a tubular nozzle below the flange. Part of pipe wall at two sides of the central axis of the tubular nozzle extends upwards to be higher than the upper end face of the flange so as to form two vertically-arranged strip-shaped members which are parallel to each other. The periphery of the strip-shaped member is cut downward to the lower part of the flange so as to form an elastic claw connected onto the lower pipe wall of the tubular nozzle. The upper outer-wall of the elastic claw extends outwardly in the radial direction so as to form a cone-shaped bulge. The improvement is as follows: part of pipe wall of the tubular nozzle among elastic claw extends upwards to be higher than the upper end face of the flange so as to form a baffle plate; and the pipe end of the fertilizer spray pipe is hinged to the annular baffle plate. According to the invention, fertilizer spray is uniform, replacement of the fertilizer spray nozzles is fast and convenient, and the fertilizer spray work efficiency of the plant-protection fertilizer spray machine is remarkably enhanced.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a fertilizer spraying pipe for a plant protection fertilizer spraying machine. Background technique [0002] During the growth period of crops, it is necessary to continuously replenish water and spread fertilizers in time to ensure crop yields. Now there are mechanical fertilizer spreaders instead of manual fertilizer spraying operations, which are highly efficient and labor-saving. The existing mechanical fertilizer spreader is arranged on a walking power machine and is provided with a centrifugal throwing structure. The power of the walking power machinery is transmitted to the centrifugal throwing structure through the transmission system, and the centrifugal throwing structure is driven to rotate, and the fertilizer is thrown into the farmland in a centrifugal manner. This method can realize mechanical spreading, but the defect is that : The range of centrifugal ferti...

AI Technical Summary

Problems solved by technology

The power of the walking power machinery is transmitted to the centrifugal throwing structure through the transmission system, and the centrifugal throwing structure is driven to rotate, and the fertilizer is thrown into the farmland in a centrifugal manner. This method can realize mechanical spreading, but the defect is that : The range of centrifugal fertilizer spreading depends on the speed of the walking power machinery. If the speed is fast, the fertilizer spreading range will be large; Spreading range, there is no guarantee of uniform spreading
