Abstract

The invention discloses a boat-type pneumatic rice paddy planter capable of carrying out front position deep fertilizing. The boat-type pneumatic rice paddy planter mainly comprises a boat body, a power nose, a fertilizer discharging device, a seed discharging system, a double-cavity type pneumatic seed discharging device and the like. When the planter is in a working state, the positive pressure and negative pressure of two cavities of the seed discharging device are changed through an air pressure valve, the rotating speed of a seed discharging shaft is changed through a gearbox, the vertical position of a seed discharging device assembly is changed through a lifting handle, and the fertilizer discharging amount and the position of a seed and fertilizer furrow opener are changed through a speed regulating valve and a four-position three-way hand-operated directional valve. The boat-type pneumatic rice paddy planter is novel in structure; a boat tractor serves as a power chassis, the fertilizer discharging device is arranged in the front part, and thus the gravity center of the boat body is balanced; front position deep fertilizing is adopted, and growth of the main root systems of seeds is promoted; the double-cavity type pneumatic seed discharging device is adopted, and the boat-type pneumatic rice paddy planter capable of carrying out front position deep fertilizing with the boat tractor as the power chassis is simple in overall structure and capable of completing a series of procedures such as seed and fertilizer furrow opening, fertilizing, seed furrow opening, seeding and impounding ditch opening at a time, and has good application prospects.

Description

technical field [0001] The invention relates to the technical field of sowing machinery in agricultural machinery, and in particular to a boat-type air force positive position deep fertilization rice direct seeding machine, which is suitable for direct rice direct seeding. Background technique [0002] The direct seeding technology of rice is a cultivation method that directly sows soaked and accelerated germination seeds in fields without raising seedlings or transplanting. At present, the common rice mechanical planting methods in my country are mainly organic transplanting, sowing, and machine direct seeding. The transplanter technology is relatively mature, but most of the transplanters are suitable for large fields after rectification, and need to raise seedlings and transplant seedlings in advance. The process is complicated. The cost is high; machine sowing is to scatter rice seeds into the field disorderly, and the seed distribution in the field is disorderly, which a...
