Vegetable planting machine box

Abstract

A vegetable planting machine box comprises a heat preserving box body, wherein a plurality of trays for planting are vertically mounted in the heat preserving box body through a tray support. The vegetable planting machine box is characterized by further comprising a temperature control system and a nutrient solution circulating system, wherein the temperature control system comprises a compressor, a condenser, a temperature sensor and a condensing coiled pipe, the condensing coiled pipe is mounted at the bottom of the heat preserving box body, the nutrient solution circulating system comprises a nutrient solution box, a water supply pump, a water supply pipe and a fixed-position draining system mounted on each tray, a nutrient solution in the nutrient solution box is filled into the topmost tray by the water supply pump through the water supply pipe, the nutrient solution in the tray is discharged to a preset height by the fixed-position draining system, and the nutrient solution box is placed above the condensing coiled pipe. The vegetable planting machine box saves energy and is low in noise, simple in structure and low in production cost, and temperature in the machine box is easy to control.

Description

technical field [0001] The invention relates to vegetable planting equipment, in particular to an indoor vegetable planting machine box. Background technique [0002] Water and soil pollution, high levels of pesticide residues, and excessive heavy metals seriously affect the quality of vegetables and fruits, and even affect people's food safety. For this reason people begin to carry out the planting of vegetable and fruit on balcony and indoor. However, due to the particularity of the environment required by vegetables and fruits, it is difficult for most people to grow vegetables and fruits with good quality and high yield. For this reason, some people have invented professional vegetable growing equipment. [0003] The air-cooled fresh-keeping cabinet uses cold air or hot air to blow from top to bottom through the fan to achieve temperature uniformity and regulation. This structure can achieve uniform temperature in the fresh-keeping cabinet with smooth ventilation and n...

AI Technical Summary

Problems solved by technology

However, when planting vegetables, planting trays are placed on each floor. There is no ventilation in the middle of the planting trays, and there are only air ducts less than one centimeter around. Medium, hot in the middle, cold all around, uneven temperature

This fresh-keeping cabinet has the advantages of simple structure, low power consumption, low noise, and large effective volume, but its disadvantages are slow radiation cooling speed, easy frosting, and poor temperature uniformity.

When it is used to grow vegetables, a large amount of condensation and hanging water often appear on the four walls of the cabinet. In the same layer, the middle is hot, the surrounding is cold, the temperature is uneven, the heat capacity of the air is small, and the cooling radiation efficiency is low, making the compressor basic Start once an hour, which increases the power consumption of the compressor, and frequent starts seriously affect the life of the compressor
