The setting of the flow guide device 3 can avoid the falling of the shaving material on the chain 21 when being added, effectively solve the problem that the scraper cannot normally operate due to the material sticking to the chain 21 and the chain wheel 23, and the same structure design as the existing scraper is used in the above embodiment.

[0029] Importantly, the flow guide device 3 of the embodiment comprises a support 31 and two flow guide pieces 32; the support 31 is fixedly connected in the machine box 1; the two flow guide pieces 32 are rotationally connected in the middle of the support 31 with one side close to each other, the two rotationally connected positions are located directly above the chain 21, and the other side of each of the two flow guide pieces 32 is provided with a strip-shaped opening 321 extending along the width direction of the flow guide piece 32, a limiting piece 33 is arranged in the strip-shaped opening 321 in a penetrating manner from top to bottom, the upper end of the limiting piece 33 is threadedly connected with the support 31, and the lower end of the limiting piece 33 abuts against the lower surface of the flow guide piece 32; the limiting piece 33 is relatively movable along the strip-shaped opening 321, so that the rotation of the flow guide piece 32 can be driven by screwing the limiting piece 33, so as to adjust the inclination angle of the flow guide piece 32, to adapt to the flow and characteristics of different shaving materials, reduce the risk of material sticking, and ensure the uniform distribution of the shaving material along both sides of the chain 21, avoid unilateral accumulation, and improve the load balance of the material plate 22; in addition, the angle adjustment of the flow guide piece 32 can be completed by simply screwing the limiting piece 33, without disassembling the overall structure, so that the equipment maintenance cost is reduced.

[0030] As a preferred embodiment, the support 31 is provided with two supports to improve the stability of the flow guide piece 32, the two supports 31 are located at both ends in the machine box 1, and the two supports 31 are hidden on both sides of the hopper 11, to prevent affecting the falling of the shaving material from the hopper 11 and improve the production efficiency.

[0031] As the preferred embodiment, the support 31 comprises a support strip 311 and two L-shaped strips 312; the support strip 311 is spaced apart from the inner top wall of the cabinet 1 and is provided with a circular through hole for the limiting member 33 to pass through, so as to prevent the limiting member 33 from being affected by the upward movement when being screwed; the two ends of the support strip 311 are fixedly connected to the two inner side walls of the cabinet 1 by screws; the vertical edges of the two L-shaped strips 312 are welded to the middle part of the support strip 311 and correspond to the two flow guides 32 respectively, and the two L-shaped strips 312 are opposite to each other to prevent the horizontal edges from affecting the rotation of the flow guides 32.

[0032] As the preferred embodiment, the limiting member 33 is a bolt, the head of the bolt abuts against the lower surface of the flow guide 32, the rod of the bolt passes through the strip-shaped opening 321 and penetrates and is threadedly connected to the horizontal edge of the L-shaped strip 312, and the rod of the bolt is threadedly connected to the nut located on the upper surface of the horizontal edge of the L-shaped strip 312, so as to improve the stability of the bolt.
