Rotary tilling, stubble breaking, fertilizing, sowing and ditching combined operation machine for wheat after rice in wet and rotten field

Abstract

The invention relates to the field of agricultural machines, and discloses a rotary tilling, stubble breaking, fertilizing, sowing and ditching combined operation machine, capable of adapting to fieldoperations in a high-humidity zone, for wheat after rice in a wet and rotten field. The combined operation machine comprises a frame, a hitching device, a sowing and fertilizing device, a rotary tilling device and a selective ditching device; the frame is a load-bearing component of the combined operation machine; the hitching device is mounted on the frame, and is connected with a power mechanical suspension device; the sowing and fertilizing device can be driven by a motor independently to perform sowing and fertilizing operations of a precise and small quantity; the rotary tilling device includes a reverse-rotating cutter shaft group and a forward-rotating small cutter shaft group, wherein the reverse-rotating cutter shaft group is installed on brackets at two sides below the frame, and an adjustable baffle is arranged behind the reverse-rotating cutter shaft group to relieve the condition that wet soil drops backwards to block seed dropping tubes, while the forward-rotating smallcutter shaft group is arranged on connecting plates at two sides behind the seed dropping tubes, and is used for covering seeds with soil; and the selective ditching device includes a cutterhead, a scattered soil guide plate, a ditch shape finishing device and the like. The invention has the advantages that the rotary tilling, stubble breaking, fertilizing, sowing and ditching combined operation machine for the wheat after rice in the wet and rotten field is designed, adapts to operation conditions of the high-humidity zone, avoids the problems that the seed dropping tubes are blocked, clay adheres to conventional press wheels and even seeds are carried, formed ditch shapes are irregular, and the like, improves weather adaptability and regional adaptability of the combined operations, andcan realize operations of rotary tilling, fertilizing, sowing, covering with soil, ditching and the like of the wheat after rice once, so that the efficiency of the field operations is increased, andlabor intensity is relieved.

Description

technical field [0001] The invention relates to a compound machine for sowing rice stubble and wheat, in particular to a compound machine for rice stubble, stubble removal, fertilization, sowing, ditching and ditching, which is suitable for field operations in high-humidity areas, and belongs to the technical field of agricultural machinery. Background technique [0002] In recent years, my country's joint operation tools have developed rapidly. It mainly includes sowing-fertilization combined operation machine, tillage-sowing combined operation machine, soil loosening-fertilization-film-mulching-hole planting combined operation machine, water application-sowing combined operation machine, film-laying and sowing combined operation machine, etc. Some units have started research on straw crushing and rotary tillage and sowing compound machines, and developed products with fewer models. However, most models are mainly aimed at conservation tillage in the north, and are not sui...

AI Technical Summary

Problems solved by technology

However, most models are mainly aimed at conservation tillage in the north and are not suitable for the characteristics of rice-wheat rotation in the south

A small number of models can complete crop straw crushing, root stubble removal, loose soil, sowing, fertilization, mulching, suppression and other operations at one time. homework defect

[0003] For areas where rice and wheat are double-cropped, there is a lot of rain in the rice stubble cultivation season or there is excess water in the field, and the fields are wet and rotten. When rice stubble and wheat production operations are carried out in such high-humidity fields, wheeled tractors will sink, and it will be difficult to walk and cannot work. ;The wet
