The first sliding joint block is slidingly connected to the guiding rod, and an upwardly extending transfer shaft is provided in the control chamber. The shaft penetrates the top wall of the straight plate and enters the second cavity, and the end of the adapter shaft in the second cavity is fixed with an upwardly extending external spline shaft.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to an agricultural straw crushing device. Background technique [0002] At present, the utilization rate of crop straw is getting higher and higher, and it is mainly processed into straw, nutrients, papermaking raw materials, etc. However, the straw has a certain length and needs to be pulverized to obtain smaller particles for easy processing. In some large processing plants or Intelligent agricultural straw crushing devices with a high degree of automation are generally used in planting bases. However, self-employed farmers also account for a large proportion of agricultural planting in my country. For these individual growers, they cannot install such large-scale intelligent agricultural straw crushing devices. In the existing technology, there are also many methods with relatively low cost of use, but their operations are too cumbersome and inefficient, and there ar...

[0002] At present, the utilization rate of crop straw is getting higher and higher, and it is mainly processed into straw, nutrients, papermaking raw materials, etc. However, the straw has a certain length and needs to be crushed to obtain smaller particles for easy processing. In some large processing plants or Intelligent agricultural straw crushing devices with a high degree of automation are generally used in planting bases. However, self-employed farmers also account for a large proportion of agricultural planting in my country. For these individual growers, they cannot install such large-scale intelligent agricultural straw crushing devices. In the existing ones, there are also many relatively low cost of use, but their operation is too cumbersome and inefficient, and there are major disadvantages, which cannot meet the existing needs
