Multifunctional rotary tillage ditching combined seed and fertilizer drill

Abstract

The invention discloses a multifunctional rotary tillage ditching combined seed and fertilizer drill which comprises a rack, wherein a fertilizer apparatus, a rotary tillage ditching device and an auxiliary ditching device are arranged at the front part of the rack, and a sewing device, a ditching device and a ditching device height adjustment device are arranged in the middle of the rack; a suppressing earth covering device and a ditch protection device are arranged at the rear part of the rack, and the ditch protection device is connected with a ditching cutter and used for adjusting the drainage ditch dimension according to the actual condition; a speed changer which is connected with an external power output end is arranged on one side of the rack, and a speed measurement wheel which is used collecting the machine tool advancing speed is arranged at the rear part of the same side. The ditch protection device comprises a ditch protection base plate, ditch protection side plates anda first square pipe, the ditch protection side plates are arranged on the two sides of the ditch protection base plate, and the first square pipe is fixed in the middle of the ditch protection base plate; the other end of the first square pipe is connected with the rack, and each ditch protection side plate is connected with the ditch protection base plate by turnbuckles. According to the multifunctional rotary tillage ditching combined seed and fertilizer drill, rotary tillage, ditching, fertilizing, sewing and suppressing operation can be performed simultaneously during one-time operation.

Description

technical field [0001] The invention relates to a multifunctional rotary tillage and fertilization seeder capable of sowing wheat and rice, and belongs to the technical field of seeders in agricultural machinery. Background technique [0002] The deficiencies of most of the planters currently on the market are as follows: 1) At present, only one kind of fertilizer can be applied to domestic machines, but some large farmers will use two kinds of fertilizers, compound fertilizer and urea, to increase soil fertility before planting. This will make the fertilization process repeated, increase the cost, and delay the sowing time; 2) The southern soil needs to open drainage ditches to facilitate the drainage of water in the field, but the drainage ditches opened by existing machines will collapse during actual use. Ditch phenomenon affects the drainage effect, and the size of the drainage ditch cannot be adjusted, which cannot meet the ditching requirements of different regions; 3...

Problems solved by technology

[0002] The deficiencies of most of the planters currently on the market are as follows: 1) At present, only one kind of fertilizer can be applied to domestic machines, but some large farmers will use two kinds of fertilizers, compound fertilizer and urea, to increase soil fertility before planting. This will make the fertilization process repeated, increase the cost, and delay the sowing time; 2) The southern soil needs to open drainage ditches to facilitate the drainage of water in the field, but the drainage ditches opened by existing machines will collapse during actual use. Ditch phenomenon affects the drainage effect, and the size of the drainage ditch cannot be adjusted, which cannot meet the ditching requirements of different regions; 3) The connection method between the opener and the frame is inconvenient to change the height and position of the opener; 4) The suppression device Most of them are suppressed as a whole, and they cannot be suppressed according to different conditions in different locations of the land, which makes the sowing depth inconsistent and affects the quality of sowing and crop yield
