Wheat seeding machine

Abstract

The invention belongs to the technical field of agricultural machinery, and discloses a wheat seeding machine which comprises a front driving harrow and a seeding machine. The seeding machine is closely fixed onto the front driving harrow through double beams and two side pulling plates, the front driving harrow mainly comprises a main fixing frame, floating traction shafts, a driving harrow and aplurality of front pressure wheels (20). The wheat seeding machine is characterized in that the floating traction shafts connected with a pull tractor are mounted on the fronts of two side pulling plates of the main fixing frame, the floating traction shafts vertically float and are movably connected with the driving harrow, the front pressure wheels and the driving harrow are split and are fixedly connected with the driving harrow through pulling plates, double-copying pressuring wheel shafts (21) are mounted on the rear portions of two sides of the main fixing frame, and the front pressurewheels (20) are mounted on the pressuring wheel shafts. The wheat seeding machine has the advantages that machine and tools are stable, the driving harrow is wide, the number of seedling ridge is morein the same width, and passing ability is good.

Description

Technical field: [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a wheat seeder. Background technique: [0002] At present, there are mainly two types of wheat seeders in China: drill drills and wide-width seeders. The wide-width precision sowing technology is a wheat sowing technology vigorously advocated by the state in recent years. There are only two kinds of wheat wide-width seeders in the market: direct Wide-width seeders with traction disc or columbine leg openers and powered no-tillage seeders (rotary tillage seeders); direct traction disc or columbine leg opener seeders need the help of a tractor The three-point suspension adjusts the balance and sowing depth. Because of its light weight and poor penetration into the soil, it is difficult to grasp the sowing depth, and it is easy to appear the phenomenon of inconsistency between the left and right depths; and it is easily affected by straw, causing straw co...

AI Technical Summary

Problems solved by technology

Due to the structural problems of the disc opener, the distance between the ditching disc and the ditching disc is too small, which can easily lead to straw blockage; in order to ensure the normal operation of the rotary tiller, the operating efficiency is also reduced; the seeder without the opener The same seeding efficiency is low, and the suppression is not real

The disadvantages of the above two planters are that the ratio of the seedling belt is sacrificed to ensure the passability, which does not meet the technical requirements of the wide seeder with a seedling belt ratio of 0.7 or 0.8:1; the seeding depth cannot be consistent and uniform; The suppression is not solid, cold winter and drought years affect the growth of wheat root system in winter; the sowing efficiency is low and the adaptability is poor, so it cannot be directly sown on the plot after deep plowing
