Trenching device of ploughing and sowing combined machine

Abstract

The invention discloses a trenching device of a ploughing and sowing combined machine. The trenching device comprises a casing, a stirring barrel and a sowing barrel, rollers are arranged in the lowerends of the two sides of the casing respectively, the stirring barrel is arranged in the casing, the sowing barrel is arranged on right of the stirring barrel, a water tank is arranged on right of the sowing barrel, a feed port is arranged in the upper end of the stirring barrel, and a first motor is arranged on right of the feed port and connected with a stirring paddle. During use of the trenching device of the ploughing and sowing combined machine, a mixture of fertilizer and water is poured into the stirring barrel, when a barrier rod moves rightwardly, a discharging pipe is opened, a seed output pipe is closed, fertilizing is started and sowing is stopped, a rotary blade can implement trenching, the survival rate of sowing can be improved, a connecting rod is fixed, a covering shovelcan combine soil in the two sides of fertilizing and sowing trenches into the trenches, the fertilizer and the seeds are buried, a pressure roller compacts the loosening soil to certain tightness, and thus, trenching, fertilizing and sowing are completed.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a ditching device for an arable land sowing combined machine. Background technique [0002] Crop seeding machine is a planting machine for planting seeds. The seeder used for a certain type or a certain crop is often named by the name of the crop type, such as grain drill, corn hole seeder, cotton seeder, pasture spreader, etc. China introduced grain drills from abroad in the 1950s, Cotton seeder, etc. In the 1960s, various types of suspension grain seeder, centrifugal seeder, universal rack seeder and air suction seeder were successfully developed, and the grinding pattern seed meter was successfully developed. By the 1970s, two series of sowing intertillage general-purpose machines and grain combined seeders had been formed and put into production. Various seed drills and hole seeders for cereals, row crops, grass, and vegetables have been promoted and used. A...

Problems solved by technology

[0003] There are many types of seeders used in rural areas, but their functions are relatively single, and there are many procedures for sowing crops. The cost of using different tools is high, and there is a lack of tools that can weed, ditch, sow and irrigate in one to save costs.
