Abstract

The invention belongs to the field of agricultural machines, and relates to an earthing-type straw smashing and field-returning machine. The front end of a rack is provided with a straw collecting shovel and a traction frame, the middle of a rack is provided with a straw dewatering and smashing device, the rear end of the rack is provided with an earthing device, and the two side faces of the rackare symmetrically provided with straw smashing device transmission systems, depth limiting devices and earthing device transmission systems respectively. According to the earthing-type straw smashingand field-returning machine, a novel smashing cutter set is utilized for completing straw dewatering work and smashing work simultaneously to solve the problems that an existing machine has a heavy and complicated dewatering structure and does not have a high straw smashing rate; meanwhile, a redesigned anti-blockage screen is utilized to solve the problem that after the existing machine smashesthe straw, the screen is easily blocked. Meanwhile, after the straw is smashed, earthing work is conducted twice through the earthing device so that the smashed straw can be sufficiently mixed with soil, and then the requirement for field returning is met. The earthing-type straw smashing and field-returning machine is suitable for smashing and field returning work on straw of most tropical cropslike bananas and cassava.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and relates to a straw crushing and returning machine, in particular to a soil-covering straw crushing and returning machine used in conjunction with a tractor. Background technique [0002] In the current banana planting area, a large amount of stalks need to be cleaned up every year after the harvest season, and the conventional method is to burn them on the spot, which has caused serious environmental pollution. Because straw is a very good fertile soil biomass, many straw crushing and returning machines have been developed to realize the effective return of straw, but there are still some problems that need to be solved. [0003] Among them, a rolling and chopping combined straw crushing and returning machine can perform the dehydration pretreatment and crushing of the finished straw, but the dehydration pretreatment effect is not good, resulting in the moisture content of the straw rema...
