Multifunctional no-tillage planter

Abstract

The invention provides a multifunctional no-tillage planter which comprises a control system and at least one operation unit, the operation unit comprises a returning machine, the returning machine is fixed at the front end of a tractor, a controller is installed in a cab of the tractor, a suspension mechanism of the tractor is connected with a suspension frame, a rack is arranged at the bottom of the suspension frame, and the rack is connected with the tractor. A subsoiler, a transmission case and a fertilizing structure are sequentially arranged on the rack, the lower part of the transmission case is connected with a soil crushing structure, the fertilizing structure is connected with a fertilizer discharging motor, land wheels are arranged on two sides of the rear end of the rack, the land wheels are connected with speed sensors, the rear end of the rack is connected with a compacting structure and a seeding structure, and the seeding structure is connected with the compacting structure. And the seeding structure is connected with a seeding motor. During operation, the machine can complete the processes of straw treatment and row returning, soil loosening, soil crushing, chemical fertilizer deep application, pressing, sowing and ditching, single-seed sowing, extrusion and soil covering and the like at a time, and meets the requirements of fertilization and sowing quality under the condition that the ground surface is covered with straw.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a multifunctional no-tillage seeder. Background technique [0002] At present, my country has identified black soil conservation tillage technology as a major strategic measure for future agricultural development. The most basic requirement of conservation tillage is to cover the surface with crop stalks, which is completely opposite to cleaning or burning the surface stalks in traditional tillage. According to the requirements of conservation tillage, the current method is that before sowing, it is necessary to use the straw return machine alone to return the straw on the surface, and then use the subsoiler to loosen the soil, and then use the rotary tiller to plow the subsoiler. Crush and suppress the raised soil clods, and finally use the no-tillage seeder to fertilize and sow; at the same time, the adjustment of the fertilization amount and seeding amount of...

Problems solved by technology

According to the requirements of conservation tillage, the current method is that before sowing, it is necessary to use the straw return machine alone to return the straw on the surface, and then use the subsoiler to loosen the soil, and then use the rotary tiller to plow the subsoiler. Crush and suppress the raised soil clods, and finally use the no-tillage seeder to fertilize and sow; at the same time, the adjustment of the fertilization amount and seeding amount of the currently used no-tillage seeder is realized by changing the transmission ratio of the gear chain. In this way, In the process of adjustment, the method is complicated, time-consuming and labor-intensive, and there are disadvantages of excessive errors in fertilization and seeding amount, which cannot guarantee the accuracy of seeding and fertilization amount; and before sowing, various machines need to enter the field for many times, resulting in waste. The working hours increase the operation cost, and at the same time, the operation effect is not up to standard, the efficiency and benefit are very low, and the best operation opportunity may be missed, resulting in soil moisture loss, lack of seedlings and broken strips; at the same time, the cost of purchasing the machine is also greatly increased; therefore, Research and develop a new type of agricultural machinery that can complete the processes of straw return, soil loosening, crushing, compaction, deep application of chemical fertilizers, sowing and ditching, single-grain planting, squeezing and covering soil and then compaction at one time during operation, and can realize fertilization The precise control of seeding rate and seeding rate is a technical problem that those skilled in the art need to solve urgently.
