Adjustable straw processor

Abstract

The invention discloses an adjustable straw processor. The processor comprises a mounting frame, a decelerator is arranged on one side of the upper surface of the mounting frame, the decelerator is connected with an external transmission device, surfaces of both sides of the decelerator are respectively connected with transmission shafts, first belt pulleys are arranged on one ends of the transmission shafts, grooves are respectively formed in the middle of the two ends of the mounting frame, bearings are clamped in the grooves, first rotating shafts are sleeved with the two bearings, and crushing mechanisms are evenly distributed on the outer surfaces of the first rotating shafts, two ends of the first rotating shafts are provided with second belt pulleys, the second belt pulleys are connected with the first belt pulleys through belts, the upper surface of the mounting frame is provided with a connecting frame, a traction mechanism is arranged on the side surface of the connecting frame, both sides of the left end of the mounting frame are respectively provided with fixing frames, and connecting blocks are arranged on the side surfaces of the fixing frames. The adjustable straw processor is convenient to use, and capable of quickly cutting and crushing straw and burying straw fragments in soil layers, straw turnover effects are good, and the depths of the soil layers where thestraw fragments are buried can be adjusted.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an adjustable straw processing machine. Background technique [0002] Straw returning to the field can increase soil organic matter, improve soil structure, loosen the soil, increase porosity, reduce capacity, and promote microbial activity and the growth of crop roots. However, if the method is improper, it will also lead to the increase of soil pathogens, the aggravation of crop diseases and the lack of seedlings (stiff seedlings) and other undesirable phenomena. Therefore, only by taking reasonable measures to return straw to the field can a good effect be achieved. For many years, the remaining straw after harvesting corn and other crops has been burned in large quantities, which has caused great pollution to the natural environment. On the other hand, due to the perennial pursuit of food High-yielding, continuously increasing crop density, thereby plundering ...

[0002] Straw returning to the field can increase soil organic matter, improve soil structure, loosen the soil, increase porosity, reduce capacity, and promote microbial activity and the growth of crop roots. However, if the method is improper, it will also lead to the increase of soil pathogens, the aggravation of crop diseases and the lack of seedlings (stiff seedlings) and other undesirable phenomena

Therefore, only by taking reasonable measures to return straw to the field can a good effect be achieved. For many years, the remaining straw after harvesting corn and other crops has been burned in large quantities, which has caused great pollution to the natural environment. On the other hand, due to the perennial pursuit of food High-yielding, continuously increasing crop density, thereby plundering the nutrients in the soil, making the soil extremely deficient in nutrients, compacted and airtight, and the bottom of the plow layer thickening year by year, causing crops to fall easily, and the situation of yield reduction is becoming increasingly severe. The straw processing machine is inconvenient to use, the straw is not completely crushed, and the straw is covered on the soil surface after crushing, and the effect of returning to the field is not ideal
