Description

Rotary tillage, fertilization, ridging, film covering and hill-drop planter

Technical Field

The invention relates to the technical field of agricultural mechanical equipment, and particularly discloses a rotary tillage, fertilization, ridging, film covering and hill-drop planter.

Background

In the dry-land rice planting process, in order to realize water saving, yield increasing, grass covering, weight losing and medicine reducing, ridging and film covering are needed, and the black full-biodegradable mulching film covered on the ridge surface is used for reducing water evaporation, inhibiting weed growth, blocking fertilizer loss and killing overwintering old larvae. At present, agricultural machinery equipment for dry-land rice film-covered planting has a plurality of functions in rotary tillage, fertilization, ridging, film covering and hill seeding, but the actual use effect is not ideal, and especially a film-covered mechanism only has a film-covered function simply, but the edge sealing in the film-covered process, film breaking and sealing head actions in the turning process of a machine tool need manual auxiliary operation.

For example, the application patent with the application number of CN201710045231.8 discloses a rice dry-planting seeder, which can finish the operations of leveling the land, paving drip irrigation pipes, paving films, pressing soil, shaping, furrow planting and seeding at one time. The machine consists of a traction part, a soil preparation part, a pipe laying part, a transmission part, a furrow film-laying soil-pressing part, a shaping part, a film edge soil-pressing part and a seeding part. The soil preparation part consists of a flat soil spade, a soil pressing roller and a ditching plow, the transmission part consists of a universal transmission shaft, a gearbox, a chain wheel and a main shaft which is driven to rotate, the furrow film-spreading soil-pressing part is characterized in that four groups of soil throwing discs are arranged on the main shaft, a plurality of blades are arranged on the soil throwing discs, soil is thrown and pressed on a film to finish soil pressing operation when the main shaft rotates, and the soil is smeared and pressed into ridges by the shaping part. The rice dry seed planter disclosed by the application has the functions of soil preparation, film laying, soil pressing, sowing and the like, but many functions are not ideal in practical effect. Taking the film laying action as an example, when the machine turns around, not only the film needs to be manually broken, but also the soil needs to be manually covered after the film breaking to prevent the mulching film from being scraped by strong wind, and then when the film is laid again after the machine turns around, the film needs to be manually torn off and the soil needs to be covered again, so that the whole rice dry land planting cannot be automatically completed. In addition, the fertilization of traditional machines is mainly by motor drive fertilizer discharging axle rotation, then drives the rotation of the inside fertilization wheel of fertilizer apparatus through the fertilizer discharging axle, and this leads to under the change condition of machine travel speed, its fertilization volume keeps unchanged, therefore the fertilization volume of unit area soil can't keep unanimous, has the problem of fertilization too much or too little, is unfavorable for follow-up even growth of rice. Therefore, the application provides a rotary tillage, fertilization, ridging and film covering hill-drop planter which can effectively solve the problems.
