Backpack type field spray sowing machine for raising seedlings with plates

Abstract

The invention relates to a backpack type field spray sowing machine for raising seedlings with plates. The machine comprises a backpack type support, wherein a seed box is arranged at the upper part of the backpack type support, the lower part of the seed box is connected with a seed metering mechanism, and the seed metering mechanism is driven by a variable frequency direct-current motor; the lower part of the seed metering mechanism is communicated with a seed falling pipe, the lower part of the seed falling pipe is communicated with the middle part of a spraying barrel, a direct current speed-regulating fan is arranged at the beginning end of the spraying barrel, and a middle connecting section of the spraying barrel is in a hose structure to be convenient to change a spray sowing direction by hands; the variable frequency direct-current motor and the direct current speed-regulating fan are supplied with electricity by an accumulator; and the rotational speed of the variable frequency direct-current motor is regulated so as to regulate the seed metering amount and the seed metering speed, and the rotational speed of the direct current speed-regulating fan is regulated so as to regulate the spray sowing distance and the spray sowing speed. The machine disclosed by the invention solves the problems that the carrying is difficult and the uniformity of seeds is easy to destroy after planting by a factory-like raising seedlings and planting production line and the like; and at the same time, the machine also solves the problems that as the existing spray sowing machine is driven by a diesel, the wind power is larger, the planting amount cannot be regulated and the uniformity of planting is poor.

Description

technical field [0001] The invention relates to a backpack-type field disc seedling-raising spray-seeding machine, which belongs to the technical field of backpack-type sowing machinery. Background technique [0002] Sowing is an extremely important part of agricultural production. "Half of the good harvest" is a summary of the importance of sowing that people have drawn from production practice for a long time. In modern precision agriculture, the requirements for the performance and quality of the seeder are getting higher and higher, and the sowing uniformity is an important indicator for evaluating the performance and quality of the seeder. In the process of seedling seedling spraying in the field, the uniformity of spraying is also an extremely important indicator. Good uniformity of spraying can fully improve the reasonable allocation of seed light, water, fertilizer, and air, so that seedlings in a single tray can emerge uniformly. The plants are thick and strong, en...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved in the present invention is: for field seedling seedling sowing, the existing industrial sowing line sowing method is cumbersome, and a slight vibration of the seedling tray may affect the sowing uniformity of the seeds or directly place the seedlings in the seedling tray. Seeds are wasted due to tipping; however, the existing spraying machines will splash the sprayed seeds everywhere, and the rice seeds cannot effectively fall into the seedling tray, resulting in a lot of waste of seeds, poor sowing uniformity, and unsatisfactory seedling raising effect
