A combined pressing roller of a ring mode straw briquetting machine

Abstract

The invention relates to an accessory of a straw briquetting machine, in particular to a combined pressure roller of a ring-mode straw briquetting machine, which is composed of a pressure roller body, a plurality of pressure roller sides and a plurality of keys; the pressure roller body is circular in shape, There is a round hole in the middle for connecting with the shaft. The side of the pressure roller is divided into equal blocks, which are divided into a boss part and a circumferential part; the edge of the pressure roller body is evenly provided with keyway holes along the circumferential direction. The number is equal to the number of the pressure roller side and the key; the periphery of the pressure roller body is provided with a hollow structure, and the key matching the shape and depth of the keyway hole of the pressure roller body is inserted into the keyway hole of the pressure roller body and passes through the boss part of the pressure roller side The keyway hole reaches the lower end surface of the pressure roller body, and the edge of the pressure roller is fixedly connected with the pressure roller body around the circumference of the pressure roller body. The peripheral parts of the pressure roller edge are combined to form a complete pressure roller around the pressure roller body. The platform part and the hollow structure form a complementary tenon fit structure. The invention realizes equipment maintenance and updating at a relatively small economic cost, and is easy and quick to operate.

[0002] Crop straw is a valuable resource. China is a large agricultural country with abundant straw resources. China's annual output of crop straw is about 700 million tons, ranking first in the world, equivalent to 353 million tons of standard coal, accounting for about 30% of the world's total straw; Because these crop straws have not been fully utilized, a large amount of incineration has become a major social problem, which not only wastes resources, but also seriously pollutes the environment. Solidification and molding of straws is a good way to solve this problem; The hole has the advantages of high productivity and low energy consumption, and has gradually become the mainstream equipment for straw solidification and molding; the ring module and pressure roller are the core components that affect the efficiency and service life of the ring mode straw briquetting machine. There are many studies on the wear of the module, such as adding bushings, replacing the die head, etc., but there are not many ways to wear the forming pressure roller; the pressure roller is a circular wheel with different tooth shapes according to different straw types. The state-of-the-art press roller has an integral structure; during the production process, due to the extrusion friction between the press roller and the straw and the ring die, the friction between the press roller edge and the flowing straw is severe, and long-term use will inevitably cause wear on the upper and lower periphery of the press roller , although it is partial wear, the transitional wear on the upper and lower sides of the pressure roller will inevitably affect the work efficiency, so the pressure roller must be replaced as a whole, otherwise it will not be able to produce normally or the production efficiency will drop sharply; generally speaking, the pressure roller with the overall structure can be used In actual production, but the structure is unreasonable. In addition to the large amount of replacement operations, its economic efficiency is not good. The waste caused by the overall replacement of the pressure roller directly reduces the benefits of resource utilization of crop straw
