A device for seed and fertilizer shared strip hole sowing with adjustable sowing rate

Abstract

The invention relates to a seed and manure shared adjustable seeding and manure spreading apparatus for both hole sowing and strip sowing. The device comprises a seeding and manure spreading device, a seed and manure case, a displacement regulator, and a loosening and uniform distribution auxiliary device. The device is characterized in that the seeding and manure spreading device is of an external spiral scored pulley type; the displacement regulator is of an arc grid type; the loosening and uniform distribution auxiliary device is of a screw auger type. The seeding and manure spreading device is installed at the bottom of the seed and manure case, and is sequentially provided with the displacement regulator and the loosening and uniform distribution auxiliary device; the displacement regulator and the seeding and manure spreading device form concentric circles; the seeding and manure spreading device, the displacement regulator and the loosening and uniform distribution auxiliary device can be made into a whole or respectively into a single one. The displacement regulator moves axially along the seeding and manure spreading device to change an effective length of the spiral groove thereon and a phase difference on the circle of the seed and manure filled in the spiral groove, and change the discharge time and discharge amount, so as to realize switching between hole sowing and strip sowing. The seeding and manure spreading apparatus can be used for seeding and manure spreading; and spiral pushing of the loosening and uniform distribution auxiliary device is beneficial for uniform distribution of the seed and manure in the case and filling of the seed and manure into the spiral groove of the seeding and manure spreading device, thereby preventing elevating or line missing.

Description

technical field [0001] The invention relates to a device for rowing and applying seed fertilizer with adjustable seeding rate for hole planting in shared strips of seed fertilizer, which belongs to the field of agricultural technology. Background technique [0002] Seeding and fertilization are an important link in the agricultural production process. Seeding and fertilizing machines are important equipment to achieve high-quality and efficient agricultural production and ensure stable and high-yield grain production; as the core components of seeding and fertilizing machines, their structure The performance and performance not only affect the quality of sowing and fertilization, but also affect the efficiency of sowing and fertilization, as well as the convenience of adjustment and maintenance; in view of the different sowing and fertilization requirements of different materials in agricultural production, different types of seed meters and fertilizers have been developed at...

[0002] Seeding and fertilization are an important link in the agricultural production process. Seeding and fertilizing machines are important equipment to achieve high-quality and efficient agricultural production and ensure stable and high-yield grain production; as the core components of seeding and fertilizing machines, their structure The performance and performance not only affect the quality of sowing and fertilization, but also affect the efficiency of sowing and fertilization, as well as the convenience of adjustment and maintenance; in view of the different sowing and fertilization requirements of different materials in agricultural production, different types of seed meters and fertilizers have been developed at home and abroad; Such as outer grooved wheel type, inner grooved wheel type, dial wheel type, spoon type, grinding disc type, disk type, centrifugal type and pneumatic type, etc. special seed metering devices for drill; different types of hole disc type, hole wheel type, hole belt type, finger-clip type and various pneumatic hole-seeding special seed metering devices; correspondingly, a wide variety of other fertilizer applicators (rows) have been developed; although these seed metering and fertilizer applicators have their own characteristics, they also have single functions, Either the structure is complicated, or the cost is too high, especially it can only be drilled or drilled, and fertilizers cannot be used universally; in modern agricultural production, not only different crops have different requirements for sowing and fertilization (some crops require seeding and fertilizer drills, there are For the same crop, hole sowing is required), even if the same crop is planted at different sowing periods, in order to ensure that it has a suitable growth density and high yield, the sowing rate should be adjusted appropriately
