Description

A disc type stubble removal rotary tillage fertilization seeder

technical field

The utility model relates to an agricultural machine, in particular to a disc type stubble removal rotary tillage fertilization seeder.

Background technique

At present, there are many machines for fertilizing and sowing in the rice-wheat rotation area at home and abroad, but the price is expensive abroad, and although the domestic price is cheap, the operation effect is relatively poor. Especially in the field with high stubble and large amount of straw, the performance of stubble removal and crushing is poor. When the straw is too long, it will not be buried deeply, and the effect of straw returning to the field will be poor.

And, when the fertilizing planter sold on the market fertilizes, especially when applying surface fertilizer, the circular fertilizing hose that adopts is easy to block, causes fertilizer to leak, reduces soil fertility. In addition, the power input of the drive shaft for sowing and fertilization is transmitted through the traditional old-fashioned chain, which is easy to cause broken or dropped chains, resulting in missed sowing and withdrawal. At the same time, this method makes the mechanism too large, resulting in energy waste. Especially in the corners of the fields, the spreading amount is uneven, which affects the spreading quality and grain output.

The fertilizer guide groove is set in front of the rotary tiller, below the fertilizer outlet of the seed fertilizer box, and the main transmission device is located between the seed fertilizer box and the three-point suspension. Between the rotary tiller and the main transmission device are connected by a rotary tiller; a soil covering device is provided at the rear end of the beam of the frame assembly, a three-point suspension is provided at the front end, and a disc type is provided under the beam of the frame assembly. The stubble removal assembly, the disc type stubble removal assembly is fixed on the bearing seat of the frame assembly; the disc type stubble removal assembly is provided with an input shaft, the lower end of the input shaft is connected by a key to install a disc type mowing blade, and the upper end is connected by a key A single V-belt pulley is installed; two V-belt pulleys are installed at the lower end of the output shaft of the main transmission gearbox, and the double V-belt pulleys are connected with the single V-belt pulley to realize power connection.

Further, the disc-type mowing blade installed at the lower end of the input shaft through a key connection is fastened through a fastening nut assembly.

Further, the single V-belt pulley mounted on the upper end of the input shaft through a key connection is fastened with a fastening nut assembly.

Further, there are two groups of disc mowing blades.

Further, the mowing blades on the disc mowing blades are serrated blades.

Further, the fertilizer guiding groove is narrow at the top and wide at the bottom.

Further, seed and fertilizer discharge are driven by stepper motors.

The beneficial effects of the utility model are: using the disc type stubble removal rotary tillage and fertilization seeder of the utility model can crush the straw with high stubble left in the front and a large amount of straw, and has good anti-winding and blocking performance and good field return effect ;The stepper motor is used to drive the seed fertilizer box for clock fertilization, the controllability is reliable and flexible, the transmission chain is reduced, the overall structure of the whole machine is compact, and the weight is light; clogged.
