small precision seeder

Abstract

The invention relates to a small-sized accurate planter. The accurate planter comprises a machine body big frame, travelling wheel wheel frames, ditching fertilizer sowing devices and seed sowing devices, wherein a main driving rod is arranged in the inner chamber of the machine body big frame in a penetrating manner; primary conical gear reversing transmission pieces which are matched with the main driving rod are arranged in positions near the middle part of the main driving rod and the two ends of the main driving rod respectively; the two primary conical gear reversing transmission pieces near the two ends of the main driving rods are in transmission connection with two secondary conical gear reversing transmission pieces inside the inner chambers of the two travelling wheel frames; the secondary conical gear reversing transmission pieces output wheel shafts of the travelling wheels; the primary conical gear reversing transmission piece at the middle part of the main driving rod is in transmission connection with a main shaft of the seed sowing device through the secondary conical gear reversing transmission piece inside a gear transmission box, a transition gear set and a seed sowing device transmission shaft; a chain wheel driven by an engine is arranged at one end of the main driving rod. Compared with conventional like products, the operation of the travelling wheels and the transmission mechanism of the seed sowing device are more stable and reliable and has the function that the planter can adapt to sowing work of various crops.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a small precision sowing machine. Background technique [0002] Most of the existing small-scale precision seeders are driven by the sprocket chain belt for the transmission of the walking wheel and the seed meter. Because the sprocket chain belt transmission mechanism occupies a large space, the sprocket chain belt transmission mechanism generally does not install a shield and It is directly exposed, so for the precision seeder that works in the mud for a long time, the sprocket chain belt transmission mechanism without the cover is easily blocked and corroded by the mud, resulting in poor transmission, wear and tear of parts, and shortened life. ; and, the exposed sprocket chain belt affects the operational safety of the machine. In addition, the seeding distance of the seed metering device assembled on the existing precision seeder is determined by the speed of the main shaft of the...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: the driving wheel of the existing small precision seeder and the sprocket chain belt transmission mechanism of the seed meter are easily blocked by mud and corroded, resulting in poor transmission, wear and tear of parts, and shortened life. The transmission mechanism causes a precision seeder to be fixed only for the seeding operation of one crop, resulting in an increase in the cost of sowing operations and a waste of idle resources. In order to solve the above problems, a transmission mechanism is provided that is more stable and reliable in operation and has a The machine is a small precision seeder suitable for the seeding operation function of various crops
