Problems solved by technology
Due to the influence and constraints of collection costs, planting scale, and operating machinery, farmers are not very motivated to collect straw. Therefore, many farmers directly burn straw in the field, causing environmental pollution and destroying the ecological environment; the current existing Most of the straw collection equipment is to chop and bundle the straw and collect it. The collected straw needs to be processed by the processing equipment again before it can be recycled. Recycling creates difficulties

The invention discloses a straw field returning device which is arranged at a straw outlet of a combine harvester. The straw field returning device comprises a straw smashing bin, a straw forming bin and a discharging bin which are sequentially communicated and vertically arranged. A straw smashing device is arranged in the straw smashing bin, the straw smashing device comprises a vertical rotating shaft, and a movable and fixed knife set and a set of hammer slices are arranged in the axial direction of the rotating shaft from top to bottom. A straw flat-die grinding and forming device is arranged in the straw forming bin. A discharging impeller is arranged in the discharging bin, and a discharging opening is formed in the position, corresponding to the discharging impeller, of the side wall of the discharging bin. Straw separated from the combine harvester is smashed through the straw smashing bin, the smashed straw is ground by the straw flat-die grinding and forming device in the straw forming bin, the straw can form straw particles of the unified specification and dimension through flat-die holes, the straw particles are finally discharged into farmland through the discharging impeller in the discharging bin so that straw recycling can be achieved, the structure is simple, and using is convenient.
Description
technical field [0001] The invention relates to the field of agricultural equipment, in particular to a straw returning device. Background technique [0002] Crop straw is a by-product of agricultural production and an important biological resource. Due to the influence and constraints of collection costs, planting scale, and operating machinery, farmers are not very motivated to collect straw. Therefore, many farmers directly burn straw in the field, causing environmental pollution and destroying the ecological environment; the current existing Most of the straw collection equipment is to chop and bundle the straw and collect it. The collected straw needs to be processed by the processing equipment again before it can be recycled. Recycling creates difficulties. Contents of the invention [0003] The purpose of the present invention is to provide a straw returning device, which can directly crush, process and shape the straw separated from agricultural crops, and return...
