Description

Automatic saw bamboo discernment conveying equipment

Technical Field

Background

The application of the moso bamboo is very wide, and the length of the mature moso bamboo is larger, usually more than 10 meters. In actual production, the raw bamboo needs to be sawed into bamboo sections with required lengths. Because the mao bamboo has more bamboo joint, the interval between two adjacent bamboo joints is mostly 10 ~ 30cm, and the bamboo joint width is mostly 0.5 ~ 1.3cm, and the bamboo joint interval at root end (head end) is littleer. In actual production, the raw moso bamboo is often sawed into moso bamboo segments (including coarse moso bamboo segments and fine moso bamboo segments) with required lengths, and the moso bamboo is often sorted, and the moso bamboo segments with required specifications are selected from the moso bamboo segments to be further produced and processed (for example, the moso bamboo segments are cut into a plurality of bamboo strips with basically consistent widths from one end in a large crusher).

A plurality of cutters of the large crusher are arranged in a conical shape to form a crushing head, a pushing block is arranged on the opposite surface of the crushing head, one end of the moso bamboo segment is aligned with the crushing head, the pushing block pushes against the other end of the moso bamboo segment and drives the moso bamboo segment to move towards the crushing head, and then the crushing head is driven to crush and cut the moso bamboo segment into bamboo chips. In the breaking and cutting process, if bamboo joints exist on one end face close to the moso bamboo section, when the pushing block pushes against the other end face of the moso bamboo section to push, the broken ends are easy to collide with the blocking face of the bamboo joints because the bamboo joints exist on one end face of the moso bamboo section, so that the moso bamboo section is easy to be stressed unstably and easily slide and shift, the bamboo pieces are not divided into different parts, and even the moso bamboo section is cracked (such as cracked) irregularly, and the defective rate is high. Therefore, it is necessary to determine whether the cut end has a bamboo joint or not and to perform a bamboo joint sawing process.

The existing moso bamboo is generally preprocessed by manual work, firstly, a worker needs to cut off the bamboo head and the bamboo tail of the moso bamboo (namely, the parts which can not be utilized) by a cutting saw, then, the rest moso bamboo is processed by fixed-length saw cutting to obtain a plurality of moso bamboo sections, then, the moso bamboo sections with the thickness capable of meeting the processing requirements are obtained by visual screening of the worker, then, the moso bamboo sections meeting the processing requirements are manually broken and cut into a plurality of bamboo strips one by one through the large-breaking machine, and then, the moso bamboo splitting operation is completed. The pretreatment work efficiency of the existing moso bamboo is low, the labor intensity of workers is high, the pretreatment effect of the moso bamboo is poor, the defective rate is high, and moreover, each process adopts relatively independent equipment for operation, and the continuous operation capability is insufficient, so that the pretreatment efficiency is very low.
