Agricultural straw treatment pneumatic conveying return-to-field device

Abstract

The invention discloses an agricultural straw treatment pneumatic conveying return-to-field device. The device comprises a casing, a feeding hopper, a first crushing chamber, a second crushing chamber, a fan, a blowing duct and a water tank, the casing is provided with the first crushing chamber and the second crushing chamber which are communicated with each other, the top of the casing is provided with the feeding hopper for feeding, the feeding hopper is communicated with the first crushing chamber for inputting straw into the first crushing chamber, a first rotating shaft is arranged in the first crushing chamber, the first rotating shaft is driven by the first motor mounted on one side of the casing, a plurality of pulverizing blades are fixed to the outside of the first rotating shaft, and a second rotating shaft is installed in the second crushing chamber. The device has the advantages that double smashing is conducted on the straw to ensure the pulverizing effect, the smashed straw can be returned to a field under the action of wind, an atomization spray head arranged can be used for spraying water on the straw, the quality of the straw is increased, so that the straw fallsquickly, and the device also contributes to the sedimentation of dust.

Description

Technical field [0001] The invention relates to the technical field of agriculture, in particular to a device for processing straws used in agriculture by air conveying and returning to the field. Background technique [0002] Straw is the general term for the stems and leaves of mature crops. Usually refers to the remaining part of wheat, rice, corn, potato, rape, cotton, sugar cane and other crops after harvesting their seeds. More than half of the products of crop photosynthesis exist in straws, which are rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc., which is a multi-purpose renewable biological resource. [0003] The treatment of straw has always been very difficult. The traditional method of incineration will pollute the environment. The crushing of straw is very complicated, which is not conducive to the operation. If the straw is not completely crushed, the effect of later utilization will be very poor. At the same time, when the stra...

Problems solved by technology

[0003] The treatment of straw has always been very difficult. The traditional treatment method of incineration will pollute the environment. Crushing straw is very complicated, which is not conducive to operation. If the crushing of straw is not thorough, the effect of later utilization is very poor. If it is caught next to it, a large amount of powder will be produced, which will have adverse effects on the body if people inhale it. At the same time, it is very time-consuming and laborious, reducing work efficiency.
