Rotary tillage, ditch forming, front-position fertilizer applying, sowing and spraying combined operation machine

Abstract

The invention relates to a rotary tillage, ditch forming, front-position fertilizer applying, sowing and spraying combined operation machine. A rotary tillage machine is arranged on the part tightly close to a ditch forming device, a rotary shaft of the rotary tillage machine is additionally provided with a plurality of side blockage clearing straight cutters, and the side blockage clearing straight cutters abut against the side tightly close to the ditch forming device; spiral delivery devices are installed on two sides of a shaft of a rotary cutting type ditch forming machine; a pedaling platform located on the rear part of a seed box is provided with a rack hinge shaft in the Y direction, a spraying rod supporting rod is hinged to the rack hinge shaft, a supporting rod hinge shaft is arranged on the spraying rod supporting rod in the Y direction, one end of a rear folding arm is hinged to the supporting rod hinge shaft, the other end is hinged to the rear end of a front folding arm,and the front end of the front folding arm is hinged to the rear part of the seed box; a locking mechanism is arranged between the front folding arm and the rear folding arm; a spraying rod is arranged at the rear end of the spraying rod supporting rod in the Y direction, and a plurality of nozzles which can spray medicine are arranged on the spraying rod. The combined operation machine has the advantages that a front-positioning manner in which fertilizers are applied below the seeds is adopted, so that the fertilizer utilization rate is improved, and the adaptability and reliability of thecombination of a synchronous applying device and a sowing machine are improved.

Description

technical field [0001] The invention relates to an agricultural mechanical device, specifically, a combined operation machine for rotary tillage, ditching, fertilization in position, seeding and spraying. Background technique [0002] Most of the existing seeders have single functions, and operations such as rotary tillage, ditching, sowing, fertilization, and herbicide spraying must be completed separately by different operating machines, and the number of times the machines are placed in the field is high, resulting in high production costs. [0003] Most of the existing planters adopt the method of direct spreading or concentrated fertilization at the position below the seed side, the utilization rate of fertilizer is low, and the position of fertilization has obvious influence on the absorption and utilization of fertilizer. [0004] The opener is an important part of the seeder. Fertilization in the right position requires the opener to open a deep ditch to apply the fe...

Problems solved by technology

However, this passive anti-blocking mechanism cannot ensure no clogging when working in sticky and heavy soil, because the clay will stick to the surface of the anti-blocking mechanism, accumulate more and more, and it is not easy to fall off by itself

[0005] In addition, in the prior art, there is also the idea of ​​installing the herbicide spraying device directly at the rear of the seeder, but due to the difficulty of combining the spraying device with the seeder and the reliability problems, it cannot reach a mature and reliable state
