Description
Technical Field
The invention relates to straw recycling equipment, in particular to a conveying device of a straw braiding machine.
Background
Straw is a general term for the stem and leaf parts of mature crops, and generally refers to the residual parts of wheat, rice, corn and other crops after harvesting seeds. During the growth process, more than half of the products of crop photosynthesis exist in the straws, and the straws are rich in nitrogen, phosphorus, potassium, calcium, magnesium, organic matters and the like, so that the straw is a multipurpose renewable biological resource. Because the straws have no direct and favorable use value, a large amount of straws, wheat straws and other straws are always burnt in the field in summer and autumn and winter every year to generate a large amount of dense smoke, which becomes an urgent problem for environmental protection.
With the technological progress and innovation, the straw recycling method finds multiple purposes for the comprehensive development and utilization of crop straws, and not only can the traditional straw returning field be used as a fertilizer, but also new ways such as straw feed, straw vaporization, straw weaving, straw power generation, straw ethanol, straw building materials and the like are provided, so that the utilization value and the utilization rate of the straws are greatly improved.
The straw mat woven by straw has wide application, can be used for product packaging, serving as an intermediate medium, surface protection and the like, and is a relatively direct recycling treatment mode. In the existing weaving equipment, although straw weaving can be realized, the following defects generally exist:
during the process of conveying the straws to the weaving station, the straws are not quantitatively conveyed, namely continuous and scattered straws are not quantitatively separated before the weaving station, so that the needle and thread paths of the woven straw mat are irregular, and the grain thickness of the straw mat is not uniform; in addition, the straw is easy to interfere with the needle and the thread, and the knitting is hindered.
