Multifunctional seeding machine

Abstract

The invention discloses a multifunctional seeding machine. The multifunctional seeding machine comprises a rack, a cross beam, a hoisting rack, a chassis, walking wheels and a transmission mechanism, wherein the chassis is fixedly arranged on the cross beam through the rack; the top end of the chassis is sequentially provided with a seeding box, a chemical fertilizer box and a farming fertilizer box; the walking wheels are arranged at the lower end of the cross beam through supporting posts; a blanking synchronizer is arranged at the lower end in the chassis; threaded adjusting rods in the supporting posts are connected with a synchronizing rod in the blanking synchronizer; a blanking adjustor with a blanking adjusting disc and a blanking device with a blanking control switch are arranged above the blanking synchronizer; three furrow openers are arranged at the lower end of the cross beam; two ends of the cross beam are respectively provided with a primary stubble cutting coulter and a soil coverer; the lower end of the cross beam is also provided with a secondary stubble cutting coulter. The multifunctional seeding machine disclosed by the invention has the advantages that the structure is reasonable, the stubble cutting effect is good, the purpose of proceeding seeding and fertilizing can be achieved at the same time, liquid fertilizer application or water injection can also be carried out on soil, the survival rate of seeds can be increased, the effect is accurate, and the seeding efficiency and the using effect of the multifunctional seeding machine are good.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a multifunctional seeder. Background technique [0002] When the existing common no-tillage seeders perform no-tillage sowing on crops such as wheat, rice, and corn, due to the thick and tough straw, cutting the straw requires a lot of power, and the amount of straw is large, and it is easy to cause stubble when cutting. Binding and jamming of cutting tools. [0003] And the traditional ditch opener, fertilizer and seeder are all set independently, not only complex installation on the sowing and fertilizing machine tool frame, but also cause the longitudinal dimension of the machine tool to be not compact, the weight of the machine tool increases, and the manufacturing cost increases. In addition, the seeding point of some seeders is far from the bottom of the seed ditch, that is, the position of the seeding point is relatively high, and the position of the seed is unstable...

Problems solved by technology

[0002] When the existing common no-tillage seeders perform no-tillage sowing on crops such as wheat, rice, and corn, due to the thick and tough straw, cutting the straw requires a lot of power, and the amount of straw is large, and it is easy to cause stubble when cutting. Winding and jamming of cutting tools

[0003] Moreover, traditional ditch openers, fertilizer applicators and seeders are all set independently, which not only complicates the installation on the sowing and fertilizing machine frame, but also causes the longitudinal dimension of the machine tool to be not compact, the weight of the machine tool increases, and the manufacturing cost increases.

In addition, the seeding point of some seeders is far from the bottom of the seed ditch, that is, the position of the seeding point is relatively high, and the position of the seed is unstable when it falls into the seed ditch, resulting in a change in the sowing distance between the plants and a decrease in the qualified rate of the plant distance, which reduces the The quality of sowing operation affects the growth of crops and the improvement of yield
