Problems solved by technology
The feeding method of mainstream tree branch crushers in the current market mostly uses the component force generated by the cutting of the branches by the crushing knife roller, and the force of the cutting of the branches by the crushing knife roller is affected by the change of the shape and diameter of the branches, which is extremely unstable. Therefore, it will inevitably affect the stability of feeding and cutting, which will lead to defects such as poor crushing effect, low efficiency and low life of the crushing knife

Embodiment Construction
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0022] Such as figure 1 As shown, the branch breaker of the embodiment of the present invention comprises a feed roller 1, a cutting roller 2, a moving knife 3 and a fixed knife 4, and the feed roller 1 is arranged on one side of the feed path of branches to be crushed, and the feed roller 1 The feeding is realized by rotation. The cutting roller 2 is set at the end of the feed path of the branches to be crushed. The moving knife 3 is installed on the side wal...

The invention provides a branch crusher and a control method and device for a feeding roller thereof. The control method comprises the steps that a controller is designed with the fact that the component force of force borne by a movable cutter in the feeding direction of branches to be crushed is equal to the component force of force borne by the feeding roller in the feeding direction of the branches to be crushed as a control rule; the diameter of the branches to be crushed is obtained; and the controller controls the rotating speed of the feeding roller according to the diameter of the branches to be crushed. According to the branch crusher and the control method and device for the feeding roller of the branch crusher, the feeding and cutting stability of the branch crusher can be improved, and therefore the crushing effect and the crushing efficiency of the branch crusher are improved, the vibration noise of the branch crusher is reduced, the energy consumption of the branch crusher is reduced, and the service life of the branch crusher is prolonged.
Description
technical field [0001] The invention relates to the technical field of wood processing equipment, in particular to a method for controlling a feed roller of a chipper, a control device for a feed roller of a chipper, and a chipper. 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] With the country's emphasis on environme...
