Ditching and soil crushing device of cultivator

Abstract

The invention discloses a ditching and soil crushing device of a cultivator, and relates to the technical field of agricultural machinery. The ditching and soil crushing device comprises a main frame,a side support and a connecting frame, one side face of the main frame is fixedly connected with one surface of the side support, one end face of the connecting frame is fixedly connected with one side face of the main frame, and the lower surface of the connecting frame is fixedly connected with the upper surface of the side support. According to the ditching and soil crushing device, by using aditch opener, a floating soil puller, a small floating soil disc and a large floating soil disc, the ditch opener can deeply loosen and turn soil in the middle of a ridge body, weeds in the middle ofthe ridge body can be pushed to the two sides while the soil is turned, and meanwhile the small floating soil disc can block the soil flying to the two sides from a front fertilization disc, the soildoes not directly press seedlings, and meanwhile, the weeds pushed by the front fertilization disc to the two sides are buried in the middle of a ridge platform again, so that the effects of retaining the soil, protecting the seedlings and burying the weeds back are achieved; in addition, the floating soil puller has the effect of pulling down parts of weeds together with roots, and also has theeffects of sealing soil and leveling soil moisture of the ridge platform; and finally, the large floating soil disc has the effects of cutting off the weeds on the ridge sides and burying the weeds, so that the soil of the ridge platform is buried in ditches.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a ditching and soil breaking device for a field cultivator. Background technique [0002] In agricultural production, intertillage and deep loose weeding is an important cultivation measure in the field management of dry fields. Cultivation is to hoe loosen the surface, turn the soil, eliminate weeds between rows and seedlings, increase the ground temperature, promote the decomposition of organic fertilizers, cut off the capillaries of the soil, reduce water evaporation, and play the role of water storage and moisture conservation. Under normal circumstances, according to different crops and different growth stages, it is necessary to carry out 2-3 intertillage operations. The first intertillage: deep loosening (blind pine) before emergence, the main function is deep loosening to relieve cold, increase ground temperature, and promote seed germination. Generally, ...
