Design and experiment of an integrated machine for embedded matrix furrowing and film covering
In order to solve the problem of narrow working space in the greenhouse of facility agriculture in Southern Xinjiang and lack of efficient operation,an integrated machine for embedded substrate cultivation trenching and film mulching is designed.The machine is composed of a frame,a furrow mulching mechanism,a power mechanism,a trapezoidal suppressing mechanism and a substrate covering mechanism,etc.The embedded substrate cultivation furrowing and mulching machine can complete a number of operations at the same time,such as ditching,mulching,shaping,soil covering and matrix discharging.By using EDEM simulation software,the ditching simulation of single soil ditching cutter and combined cutting and throwing ditching cutter was carried out.Finally,the field experiment was verified,and the results showed that the average resistance of single soil ditching cutter in the process of ditching was 329 N,and the average resistance of slicing-throwing combined ditching cutter in the process of ditching was about 338 N.The working quality of slicing-throwing combined ditching cutter is improved but the ditching resistance does not increase significantly.The ditching depth of the machine is 30 cm,the ditching depth stability is 87.1%,and the soil breaking rate after ditching is 92.4% .It provides technical reference for the mechanical operation in the greenhouse of facility agriculture in arid and remote areas.
