An intelligent profiling ditch clearing device for a furrow machine and its control method

Abstract

The invention provides an intelligent profiling ditch cleaning device matched with a bed shaper. The ditch cleaning device comprises a soil breaking mechanism arranged below a back cross beam of the bed shaper as well as a collecting and transporting mechanism supported at the front end of a frame and arranged on the right side of the soil breaking mechanism; the ditch cleaning device further comprises a profiling sensing control mechanism and a soil crushing mechanism which are in circuit connection with a PLC. The ditch cleaning device can cooperate with the bed shaper to operate to clean uneven roads and large soil blocks in bed ditches and realize consistence of height difference between bed surfaces and bed ditch bottom surfaces on any cross section of the beds according to a profiling control circuit and device, so that the better bed ditch quality is practically provided for traveling of transplantation and harvesting machinery, and the survival rate and the yield of seedlings are increased.

Description

technical field [0001] The invention relates to a soil preparation machine, in particular to an intelligent profiling furrow cleaning device, which belongs to the technical field of agricultural machinery. Background technique [0002] Compared with food crops, economic crops have higher requirements for land consolidation. Generally, border farming (or ridge farming) is used to meet the requirements of finely crushed topsoil, flat furrow surface, and straight furrows. Traditional micro-tillage ridge machines and rotary Tilling and ridge compound operation machines cannot meet the above-mentioned operation requirements. [0003] At present, only the furrowing machine disclosed in the patent document with the application number ZL201420813108.8 can realize furrows of different widths, and at the same time ensure that the furrows are uniform and have a good furrowing effect. However, in the course of the test, it was found that after the operation of the machine tool, there w...

Problems solved by technology

However, in the course of the test, it was found that after the operation of the machine tool, there was still a large amount of crushed soil accumulated in the furrows between two adjacent furrows, and uneven and uneven particle sizes were formed in the furrows. Under clay conditions, the soil clods will become extremely dry and hard in the later stage, which will have a great impact on the later transplanting and harvesting of crops. On the one hand, it cannot guarantee that the planting depths of all crop seedlings are inconsistent, resulting in different heights of cut stems during later harvesting; on the other hand On the one hand, it cannot guarantee the consistent operation depth of harvesting machines, which poses a great challenge to the control of headers, reduces operating efficiency, and increases manufacturing costs.

[0004] According to the applicant's understanding, in terms of ditch cleaning, the patent document with the application number ZL201320793287.9 ​​proposes a ditch cleaning machine with adjustable ditch width. The block falls into the ditch, although the structure is simple, there is still a lot of broken soil in the ditch after the operation, and the bottom of the ditch cannot be guaranteed; in the patent document ZL201310386050.3, a trapezoidal beam is added on the basis of the original ditch cleaning machine to realize ditch cleaning at the same time Buried in soil, used for elevated grape planting on flat land, neither of the above two kinds is suitable for border cultivation

Therefore, the cleaning device specially used in furrows (or furrows) is still blank
