Embodiment Construction
[0084] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0085] Such as Figure 1a to Figure 1d As shown, the present invention provides a kind of sowing / supplementing improvement equipment for high firmness degraded grassland composite soil layer, comprising: frame 1, profiling ditching device 2, sowing device 3, suppressing device 4, reduction box 5 and transmission device6.
[0086] The frame 1 comprises a frame left side plate 101 and a frame right side plate 102, and a front crossbeam 103, a middle frame fixed between the frame left side plate 101 and the frame right side plate 102 sequentially from front to back. Cross beam 104 , rear cross beam 105 and fixed beam 106 . The three-point suspension device 107 is fixedly connected to the front beam 103 and the rear beam 105 of the frame 1 .
[0087] The profiling ditching device 2 includes a left profiling ditching unit and a right profiling ditching un...

The invention relates to a seeding / supplementing improving machine tool and improving method for compound soil layer of degraded grassland with high firmness. The implement includes a frame, a profiling ditching device, a seeding device, a suppression device, a deceleration and a transmission device; the profiling ditching device includes a left profiling ditching unit and a right profiling ditching unit; a profiling ground wheel and The soil-breaking mechanism with adjustable breaking depth is coaxially arranged between the left side plate of the profiling ditch and the right plate of the profiling ditch; Differential speed rotation; the seeding device includes a seed box, an outer groove wheel seed metering device, a seed metering shaft, a seed guide tube and a seed drop tube; a plurality of suppression devices corresponding to the seed drop tubes are fixed on the rear end surface of the fixed beam . The present invention performs degraded grassland sowing / reseeding improvement operations in a low-disturbance manner, and realizes uniform ditching depth during operation, with small surface damage and small surface disturbance, and the problem of missed seeding caused by ground wheel slippage does not occur.
Description
technical field [0001] The invention belongs to the field of grassland ecological improvement, and in particular relates to a seeding / supplementing improvement machine tool and method for a compound soil layer of degraded grassland with high firmness. Background technique [0002] The natural degraded grassland is mainly manifested in the retrograde succession of grassland vegetation, the invasion of dominant weeds, and the formation of a compact soil-root composite soil layer structure in the subsurface layer of the grassland, resulting in a large-area compaction degradation trend of the grassland. The decline hinders the effective performance of its ecological service function. Sowing (re-seeding) is one of the effective ways to improve degraded grassland, but most of the existing sowing (re-seeding) equipment and key tillage components are used on farmland, and when applied to grassland, it is easy to cause large surface disturbance of grassland. , The degree of vegetati...
