Description

Technical Field

[0001] The utility model relates to the technical field of straw, in particular to a straw bundling and untying device for straw crushing. Background Technique

[0002] At present, in straw processing, raw materials are directly fed into straw processing equipment by means of belt conveying or chain conveying. Since the directly fed raw materials are straws that are bale-packed for easy transportation, when the straw raw materials enter the straw processing equipment, due to their high density and large weight, the impact force on the above-mentioned equipment is large. Therefore, this feeding method not only affects the production efficiency of straw processing, but also reduces the service life of the main shaft components of straw processing equipment. It is necessary to untie the straw bales before feeding.

[0003] According to a new type of straw untying device disclosed in a Chinese patent with the publication number "CN208790099U", which includes a base. One side of the top of the base is provided with a bracket, and evenly distributed rollers are provided at the tops on both sides of the bracket. The circumferential outer wall of the roller is sleeved with a conveyor belt, and evenly distributed baffles are provided on the side of the conveyor belt away from the roller. Fixed teeth are evenly distributed on one side of the baffle, and a box body is provided on the other side of the top of the base. One side of the top of the box body is provided with an extension plate, and evenly distributed air outlet pipes are provided at the bottoms of the inner walls on both sides of the box body. The top outer wall of the air outlet pipe is provided with evenly distributed air outlet holes, and an air pump is provided at the middle position of the outer wall on one side of the box body. A driving motor is provided at the bottom of the outer wall on one side of the box body. The utility model realizes the untying of straw, which is convenient and fast. The straw bale is fully contacted and stressed with the untying blade, improving the untying effect, making the straw fully dispersed after untying, and the unbundled and dispersed straw can be fed. However, when the above device cuts and unties the straw by the straw falling and hitting the untying blade, the untying efficiency is low, and it is easy to occur that the impact force generated during the fall is insufficient and the straw cannot be untied, affecting the subsequent processing efficiency. Therefore, a straw bundling and untying device for straw crushing is proposed to solve the above-mentioned problems. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a straw bundling and untying device for straw crushing in view of the deficiencies in the above-mentioned prior art.

[0012] 1. For the straw crushing and unbaling device, the bundled straw is conveyed into the crushing frame by using the conveying mechanism. The motor is started to drive the coupling rod to rotate. The coupling rod drives the rotating rod to rotate through the first bevel gear and the second bevel gear. The rotating rod drives the cutter head to rotate, and the cutter head cuts the rope on the bundled straw to achieve the purpose of unbaling. The unbaling efficiency by cutting with the cutter head is high, and the situation of unsuccessful unbaling will not occur.
