Multifunctional sowing machine

Abstract

The invention belongs to the field of agricultural machines, and particularly relates to a multifunctional sowing machine. The multifunctional sowing machine comprises a machine frame 1 and a suspension device 2. The multifunctional sowing machine is characterized in that the suspension device 2 is arranged at the front end of the machine frame 1; the suspension device 2 comprises a gearbox 21, a first transmission gear 211 and a second transmission gear 212, and the second transmission gear 212 is connected with a soil feeding device 4 and a fertilization device 5; a film hanging rack 7 and a hole puncher 8 are arranged on the back of a shaping device 6; a hole sowing device 9 is arranged on the back of the machine frame 1 and comprises a hole sowing machine 91 and a hole sowing machine frame 92; a limiting wheel 10 is further arranged on the back of the machine frame 1. According to the multifunctional sowing machine, a soil shovel capable of adjusting the opening and closing angle is arranged on the lower portion of the soil feeding device to balance soil pressure on the front portion and the back portion of the soil feeding device; by the adoption of the mode that a soil scraping plate is additionally arranged on the shaping device, neatness of the sowing faces is guaranteed; the hole puncher is arranged behind the film hanging rack, so that follow-up workloads are reduced; various crops can be sown through the precision hole sowing machine with seeds of various specifications being compatible, and the multifunctional sowing machine is of great significance to improving the crop planting efficiency.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a multifunctional seeder. Background technique [0002] The full-film double-furrow sowing technology integrates mulch suppression, rain collection in furrows, and furrow planting technologies, achieving the effects of moisture conservation and moisture storage, in-situ infiltration and rainwater enrichment. Its characteristics: First, it significantly reduces the evaporation of soil moisture. In particular, autumn mulching and topling mulching avoid the ineffective evaporation of soil moisture during the autumn, winter and early spring fallow periods, and reduce wind and water erosion. The large and small ridges in the field are good water-collecting surfaces, which can collect and infiltrate the tiny rainfall into the roots of corn, greatly improving the utilization rate of natural precipitation; third, increasing the accumulated temperature and expanding the ...

AI Technical Summary

Problems solved by technology

[0004] In summary, there are mainly the following defects in the prior art: 1. The existing soil loading device can easily cause a large amount of soil accumulation due to the unreasonable fixed angle or depth of the soil shovel below, thereby affecting the smooth operation of the entire device; Two, the existing shaping device is not equipped with a special scraper, it is difficult to ensure that the sowing surface of the crops is even after ridging, and whether the sowing surface of the crops is even directly affects whether the follow-up mechanized harvesting operation can be carried out smoothly; three, the existing The soil loading device is not equipped with a special clutch. If there is no need for film covering operations, it can be used to achieve more purposes; 4. There is no special punching device in the existing seeding device, which causes a lot of work for manual release of seedlings after emergence in the later stage. Huge; 5. In the prior art, the angle of the duckbill entering the soil on the hole planter cannot be adjusted, and the suitable angle of the duckbill into the soil will directly affect the sowing effect of the planter; 6. The existing planter can sow a single type of crop
