Stereoscopic seedling raising machine for rice

Abstract

The invention relates to a stereoscopic seedling raising machine for rice. A top cross beam, two cross beams and a bottom cross beam of a square frame type stand are respectively provided with a main supporting and reversing sprocket, an upper secondary supporting and reversing sprocket and a lower secondary supporting and reversing sprocket, a transmission chain tension regulation mechanism with a tension reversing sprocket is arranged at the middle part of the bottom cross beam, the right end part of the bottom cross beam is provided with a driving shaft, the driving sprocket and two transmission sprockets are sequentially and fixedly arranged on the driving shaft, a driving chain is sleeved on the driving sprocket and an active sprocket of a motor, two transmission chains are sequentially connected onto the transmission sprockets, the upper secondary supporting and reversing sprocket, the lower secondary supporting and reversing sprocket, the tension reversing sprocket and the main supporting and reversing sprocket, a lifting basket type tray is hinged to and arranged on the transmission chains, and a spraying device which is combined and communicated with a motor water pump is arranged in the square frame type stand. The stereoscopic seedling raising machine disclosed by the invention has the advantages of high ratio of saved seedling raising soil, novel and reasonable structure, high degree of automation, good operation quality and reliability in use.

Description

technical field [0001] The invention belongs to agricultural seedling raising machines, and mainly relates to a vertical rice seedling raising machine. Background technique [0002] In recent years, with the continuous increase of rice planting area in Heilongjiang Province in the northern part of China, the flat seedling raising method in rice greenhouses has affected many reasons due to its large land occupation, low land utilization rate, and the shortage of land resources. And restrict the development of agricultural production. Accordingly, the industrial three-dimensional rice seedling raising method began to be applied in agricultural production. At present, a kind of vertical rotary wheel type rice vertical seedling equipment has been studied, which can reduce the occupied area by 1 / 2 compared with the traditional flat seedling raising method. However, the research and development of continuing to reduce the high-quality land resources occupied by seedling raising ...
