Abstract
Description
Technical Field
[0001] The utility model relates to an agricultural cutter, in particular to a dry and wet straw cutter. Background Art
[0002] The most widely used and closest prior art to this invention is the straw grinding method. The straw grinding method has several major defects: 1. The straw grinding method can only process dry straw and the grinding method will cause a considerable part of the straw to become crushed. In the bio-straw power generation, the treated straw cannot generate the maximum heat, resulting in a reduction in power generation. 2. A large number of plastic belts will be wrapped around the branches or vines of many vegetable straws (the role of plastic bags: such as cucumbers, tomatoes, peppers, etc., in order to make the fruits grow more firmly on the branches and vines). The grinding method cannot effectively break the plastic belts, resulting in the plastic belts being wrapped around the feed port of the boiler and causing equipment damage. 3. Because a considerable part of it will be crushed, in a humid environment, it will increase the rot and stink of the straw, resulting in it being unable to be reused. 4. The crushing method cannot process fresh straw, because the fresh straw itself has a high moisture content. After grinding, it will become a porridge-like substance, which will further cause rot and stink, and lose its own economic and environmental benefits. 5. Vegetable or melon farmers often pile fresh straw on both sides of the road to dry naturally. If the local political and legal departments do not get involved in the handling, fires often occur, resulting in unnecessary economic losses.
[0003] For this purpose, the present application document provides a dry and wet straw cutting machine. Utility Model Content

In this way, including the plastic belt in the cutting process, it will become segmented straw. In the bio-power generation industry, it can generate heat to a maximum extent to generate electricity, and the cut plastic belt will not damage the machine. The straw cutting method has greater advantages in cutting fresh straw, because it is cut instead of grinding, and the fresh straw will not become porridge, but will be cut into segmented straw. Because the plastic belt itself is entangled in branches and vines, it will be easier to be cut. As long as there is a way to deal with the fresh straw, they can be recycled. In this way, vegetable farmers or melon farmers will no longer pile the freshly pulled straw on the sides of the road. BRIEF DESCRIPTION OF THE DRAWINGS
