Double-row peanut seeder on rotary tillage stubble ploughing separated layer fertilization ridge

Abstract

The invention belongs to the agricultural production machines, and particularly relates to a double-row peanut seeder on a rotary tillage stubble ploughing separated layer fertilization ridge. A rotary cultivator gearbox (20) is fixedly arranged on a front cross beam of a main machine frame (1), and a front fertilizer conveying guide tube (33) below a front fertilizer box (2) is inserted in a rotary cultivator protective cover (12). A bearing seat frame (42) is fixed above an auxiliary machine frame (1-3), and a bearing seat (24) is fixed on the bearing seat frame (42). A seed discharging chain wheel (18) is arranged at the right end of a seed discharging device shaft (44), and land axles (43) are arranged at the positions below the two sides, corresponding to the seed discharging device shaft (44), of the main machine frame (1) by land wheel bearing frames (23). Land wheels (5) are arranged at the two ends of the land axles (43), and a front fertilizer discharging chain wheel (17), a rear fertilizer discharging chain wheel (19), the seed discharging chain wheel (18) and a land wheel chain wheel (16) are in transmission connection by a same chain (15). The double-row peanut seeder on the rotary tillage stubble ploughing separated layer fertilization ridge solves the difficult problem that ridge sealing can not be achieved due to large ridges, and the effect of reducing wind erosion and soil water loss is achieved.

Description

technical field [0001] The invention belongs to machinery for agricultural production, in particular to a double-row peanut planter on a ridge for layered fertilization with rotary tillage and stubble removal. Background technique [0002] At present, the general row spacing for corn planting in northern my country is 300 mm. When planting peanuts in the original ridge, the ridge cannot be closed due to the large ridge, resulting in waste of land resources. In the windy and sandy land in northern my country, corn stubble can help prevent wind erosion. However, it affects the cultivation of the next stubble, because the sandy soil is barren, and improper fertilization will easily cause the loss of fertilizer and waste the fertilizer. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned technical deficiencies, and provide a double-row peanut planter on a ridge that can reduce wind erosion and water loss, reduce fertilizer w...
