Description

Technical Field

[0001] The utility model relates to the technical field of strip tillage machines, in particular to a hydraulically driven and suppressed strip rotary tillage machine. Background Art

[0002] With the development of conservation tillage technology and large ridge double-row planting mode, a technical mode of corn straw full-row coverage with wide and narrow rows has emerged. This mode refers to a technical mode in which the straw covers the surface completely after harvesting, and the rows are collected by a row collector, and wide and narrow rows are sown without tillage, and the straw is alternately covered between the rows and returned to the field. After the corn straw was returned to the field last year, under the original uniform row spacing conditions, the row collector was used to collect the row straw, and two adjacent rows or three rows were combined to plant two rows, forming a planting mode in which narrow rows are used as seedling strips and wide rows are used to place straw. Wide and narrow rows are planted alternately every other year. On this basis, strip rotary tillage machinery has emerged.

[0202] Embodiment 1:

[0203] A hydraulically driven and suppressed strip rotary tillage machine is suitable for windy and sandy arid areas. After strip tillage is implemented in spring, no-till sowing and suppression are carried out in time to prevent excessive loss of moisture in farmland soil. This technology is not suitable for plots with particularly sticky and wet soil in autumn or sowing season.

[0204] 1. Strip tillage time: Autumn strip tillage is suitable for areas with relatively humid spring climate or cool low-lying plots, and the operation should be carried out when the soil moisture is about 25% before freezing; spring strip tillage is suitable for areas or hills with relatively severe spring drought, and the operation should be carried out 0-3 days before sowing; when the soil moisture is suitable, the tillage can be carried out simultaneously, and when the soil is relatively wet and sticky, the operation needs to be carried out 2-3 days before sowing.

[0205] 2. Strip width standard: The operation of the strip tiller will form a sowing belt without straw coverage and a straw belt; the strip width is set according to the mechanical parameters of the strip tiller and the local commonly used row spacing. The sowing belt width of a field with a ridge spacing of 65 cm is 40-50 cm, and the straw belt width is 80-90 cm.

[0206] 3. Operation standard: The strip tiller can complete the operations of straw cleaning, deep tillage, shallow tillage and compaction at one time. The straw residue in the sowing belt should be less than 10%, the deep tillage depth should be 20-25cm, and the shallow tillage depth and compaction intensity should be determined according to the soil moisture, soil texture and operation time. The low-lying plots in autumn operation should be tilled 15cm and the compaction intensity should be about 3N / cm 2 ; The rotary tillage for spring operations requires less than 10cm, and the compression strength is about 4-5N / cm 2 .
