Branch crusher crushing chamber leading-in structure

Abstract

The invention discloses a branch crusher crushing chamber leading-in structure. The branch crusher crushing chamber leading-in structure comprises a crushing chamber, a fixed cutter, an access door, a crushing chamber frame, a discharge pipe and a grid type discharge guide plate, wherein the fixed cutter is mounted in the crushing chamber through a fixed cutter fastening bolt; the access door is arranged on the crushing chamber; one end of the crushing chamber is a branch rod inlet; the discharge pipe communicates with the crushing chamber frame of the crushing chamber at the other end of the crushing chamber; the grid type discharge guide plate is arranged in the crushing chamber, is positioned between the other end of the crushing chamber and the access door, and is arched; and the extension direction of the grid type discharge guide plate is partially overlapped with a cutting roller movable cutter revolving trajectory circle formed by a movable cutter mounted on a high-speed rotating cutting roller. The grid plate flaring type airflow leading-in structure enables the pressure difference to be smaller when free air outside the crushing chamber is led in, is safe and reliable in machine tool operation, is not absorbed and blocked by foreign matters (light leaves, paper pieces and the like), improves the material crushing particle size, and increases the storage, transportation and loading density.

Description

technical field [0001] The invention relates to the field of agricultural production equipment, in particular to an introduction structure for a crushing chamber of a tree branch grinder. Background technique [0002] my country is not only a big country of timber production, but also a big country of timber consumption. Improve the utilization rate of main timber production, develop timber finishing industry, collect forest logging residues, wood product factory processing residues and waste wood for papermaking and medium and high density fiberboard , Particleboard production, improving the comprehensive utilization of wood resources, reducing the waste of wood resources, has an important role and far-reaching significance in alleviating the contradiction between the supply and demand of wood in my country and meeting the demand for wood in the rapid growth of the national economy. [0003] At present, under the condition that there are many branches and tree crowns fed int...

Problems solved by technology

[0003] At present, under the condition that there are many branches and tree crowns fed into the branch shredders on the market and the load of the cutting roller is excessively increased and the speed is reduced, it is very easy to cause the risk of blockage and the phenomenon that the material discharge does not reach the predetermined area. There is a lot of room for improvement and head, and it increases the transportation cost
