Straw treatment system and treatment method

Abstract

The invention provides a straw treatment system and a treatment method, and belongs to the field of agricultural machinery. The straw treatment system comprises traction equipment, a pick-up trailer,conveying equipment and carbonizing equipment; the traction equipment is used for driving the pick-up trailer and the carbonizing equipment to move to a working site; the pick-up trailer is used for loading or unloading the conveying equipment, and pulled by the traction equipment to pick up straw after the conveying equipment is unloaded; the conveying equipment is used for receiving the straw unloaded by the pick-up trailer and conveying the straw into the carbonizing equipment; the carbonizing equipment is used for carbonizing the straw. According to the straw treatment system and the treatment method, through the reasonable arrangement of the traction equipment, the pick-up trailer, the conveying equipment and the carbonizing equipment, the semi-fixed treatment mode for straw carbonizing treatment is achieved, the overall size and weight are reduced, the turning radius during walking is reduced, the conveying flexibility and the walking speed are improved, and the efficiency of treating the straw is significantly improved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a straw processing system and processing method. Background technique [0002] The resource utilization of straw is a very good way to deal with straw, but subject to various conditions, the proportion of straw resource utilization is very small. Straw returning to the field is the current mainstream straw treatment method, but after many years of straw returning to the field, it will damage the nutrients in the soil, affect the growth of crops, and lead to the decline of crop resistance to insects and disasters; straw burning is a very simple treatment way, but straw burning will cause a lot of pollution, so the state prohibits straw burning. [0003] For this reason, a model of direct carbonization in the field is proposed. The carbonized biochar can be easily transported and post-processed, which reduces the workload in the process of straw resource utilization. The curr...

[0002] The resource utilization of straw is a very good way to deal with straw, but subject to various conditions, the proportion of straw resource utilization is very small

Straw returning to the field is the current mainstream straw treatment method, but after many years of straw returning to the field, it will damage the nutrients in the soil, affect the growth of crops, and lead to the decline of crop resistance to insects and disasters; straw burning is a very simple treatment way, but straw burning will cause a lot of pollution, so the country prohibits straw burning

[0003] For this reason, a model of direct carbonization in the field is proposed. The carbonized biochar can be easily transported and post-processed, which reduces the workload in the process of straw resource utilization. The current model of direct carbonization in the field uses straw The carbonization system is used for processing. The straw carbonization system generally includes processing equipment such as picking up, conveying, and high-temperature carbonization that are connected together. Taking corn straw as an example, the common four-row harvesting equipment harvests 5-7 mu of land per hour, and the straw processed per hour The capacity is more than 2 tons. The carbonization system that matches this capacity occupies a large area, is bulky and heavy. When walking in the field, it faces problems such as large turning radius and slow walking speed, resulting in low efficiency of straw treatment.
