Description

Technical Field

[0001] The utility model relates to the technical field of agricultural soil scarifying equipment, in particular to an agricultural soil scarifier capable of adjusting the soil scarifying depth. Background Art

[0002] At present, there are many types of scarifiers on the market, which are mainly used for tilling, land preparation, hoeing and cultivation. They can reduce labor intensity and are deeply loved by people, especially in developed countries. Scarifiers have become one of the necessary agricultural machinery for families. In order to improve the quality of soil cultivation and increase crop yields, it is necessary to scarify the fields regularly or before sowing crops every season. In order to improve the efficiency of scarification, agricultural scarifiers are generally used to scarify the fields.

[0003] After searching, the patent announcement number CN208836472U discloses a garden tiller with adjustable tillage depth, which relates to the technical field of garden construction. The garden tiller with adjustable tillage depth includes a tiller body, a tillage roller is sleeved inside the tiller body, a telescopic rod is sleeved inside the tillage roller, a bearing is sleeved outside the telescopic rod, a first connecting bolt is welded on the bearing, the first connecting bolt is hinged with a connecting rod through a bolt, and the end of the connecting rod away from the bearing is hinged with a second connecting bolt through a bolt. The garden tiller with adjustable tillage depth controls the telescopic rod to extend and retract through a thread, so that the connecting rod hinged on the first connecting bolt moves, so that the other end of the connecting rod stretches the tiller claw, so that the tiller claw retracts and retracts, thereby achieving the purpose of controlling the tillage depth. Compared with the existing garden tiller, the tiller depth becomes easier to control, avoiding the situation where the staff repeats the work due to insufficient tillage depth, saving labor costs and improving work efficiency.

[0004] The existing agricultural tiller can adjust the tiller depth during actual use, but the adjustment operation is cumbersome, which affects the efficiency of tillering, is inconvenient for the staff to use, and is also inconvenient for the maintenance personnel to disassemble, repair or replace the tiller claws. Therefore, we propose an agricultural tiller with adjustable tiller depth to solve the existing problems. Utility Model Content
