[0072] Referring to the accompanying Figure 1 — Figure 7 As shown in the drawings, in the utility model, the guide plate body 1 is provided with a first sealing groove 12, the first sealing groove 12 is provided with a first sealing ring 13, and the first sealing groove 12 is located at the channel opening of the oil guide main channel 51 close to the oil guide communication channel 54.

[0073] The utility model can effectively prevent the lubricating oil from flowing out of the connection between the oil guide main channel 51 and the oil guide communication channel 54 through the setting of the first sealing groove 12 and the first sealing ring 13.

[0074] Referring to the accompanying Figure 1 — Figure 12 As shown in the drawings, the working process of the lubricating system of the utility model is as follows:

[0075] Firstly, the oil supply unit on the felling equipment provides pressure oil into the oil inlet 53 in the oil supply channel 5 into the oil inlet channel 52, flows along the oil inlet channel 52 to the oil guide main channel 51, along the oil guide main channel 51 into the oil guide communication channel 54, and finally flows out from the oil outlet 55 in the oil supply channel 5 into the space between the inner support body 31 and the outer ring body 33, i.e. the space where the rolling member 32 is located. As the lubricating oil is a high-temperature lithium-based grease and other solid lubricating oils, the lubricating oil does not flow out immediately but gradually increases. When the lubricating oil fills the space where the rolling member 32 is located, the lubricating oil in the control will flow out through the first through hole 312 into the space between the outer ring body 33 and the inner support body 31, i.e. to lubricate the rolling member 32, so that the rolling member 32 is in the lubricating oil during rotation. With the filling of the lubricating oil between the outer ring body 33 and the inner support body 31, the lubricating oil will finally be sprayed from the oil injection hole 332 and contact the transmission wheel 4. The centrifugal force generated by the rotation of the transmission wheel 4 will cause the lubricating oil to fly off, and the flying lubricating oil will contact the saw chain to lubricate and cool the saw chain.

[0076] It should be particularly noted that when the saw chain guide plate is in use, the clamping plate on the oil supply unit will clamp the saw chain guide plate. Therefore, it is necessary to ensure that the oil supply port on the oil supply unit is in communication with one of the oil inlets 53, and the remaining oil inlets 53 will be blocked by the clamping of the clamping plate. The transmission wheel 4 in the present application can be a grooved chain wheel or a toothed chain wheel.

[0077] Embodiment 2

[0078] Referring to the drawings Figure 13 — Figure 16 The difference between the present embodiment and the above-mentioned embodiments is that, in the present embodiment, the driven support structure 2 includes a connecting plate 201 arranged on one end of the guide plate body 1, a mounting plate 202 integrally formed with the connecting plate 201, a second through hole 203 arranged on the mounting plate 202, and a rotating structure 3 fixedly installed in the second through hole 203. The connecting plate 201 is integrally formed with the guide plate body 1 or is fixedly connected by riveting. The thickness of the connecting plate 201 is equal to or greater than the thickness of the guide plate body 1, and the thickness of the connecting plate 201 is less than the width of the sawing path of the saw chain movement. The thickness of the mounting plate 202 is less than the thickness of the guide plate body 1, and the guide plate body 1 is symmetrically arranged about the mounting plate 202.

[0079] The mounting plate 202 is connected with the guide plate body 1 through the connection of the connection plate 201, and the guide plate body 1 is symmetrically arranged about the connection plate 201, so that the distance from the connection plate 201 and the mounting plate 202 to the top surface and the bottom surface of the guide plate body 1 is equal, and the connection plate 201 is limited in thickness to be less than the sawing path width generated by the movement of the saw chain, so that the jamming in the wood cutting operation can be effectively prevented; the second through hole 203 is arranged to provide a mounting position for the rotating structure 3, and when the rotating structure 3 is mounted, the outer ring body 33 in the rotating structure 3 is fixedly mounted on the hole wall of the second through hole 203, and the outer ring body 33 is limited by the cover 34, and since the cover 34 and the inner support body 31 are in interference fit, even one of the covers 34 can be integrally formed with the inner support body 31, so that the inner support body 31 can be fixed.

[0080] Referring to the drawings Figure 13 Figure 16 In the embodiment, the outer ring body 33 is provided with a first lubricating hole 331; the transmission wheel 4 is composed of two rotating plates 41 which are the same in structure and are respectively mounted on the two ends of the rotating structure 3; the rotating plate 41 is a circular plate, the minimum distance between the two rotating plates 41 is equal to the groove width of the saw chain guide groove 11, the maximum distance between the two rotating plates 41 is not greater than the thickness of the mounting plate 202, and the center position of the rotating plate 41 is provided with a second recess 42 corresponding to the rotating structure 3.

[0081] ​The first lubricating hole 331 is arranged in communication with the oil conveying channel 5, so that the lubricating oil can enter the space between the outer ring body 33 and the inner support body 31 to lubricate the rolling member 32. The rotating plates 41 are arranged at both ends of the rotating structure 3, that is, the rotating plates 41 are respectively arranged at both ends of the inner support body 31, so that the saw chain can be positioned and guided by the two rotating plates 41. The rotating plates 41 are circular plates, so that the distance between the central position and the saw chain does not change when the saw chain is guided, and the tension of the saw chain does not change, which can effectively prevent the saw chain from breaking. The circular arrangement makes the distance moved by the lubricating oil due to centrifugal force as equal as possible, so that the uniformity of the lubricating oil thrown onto the saw chain due to centrifugal force can be effectively ensured, and the saw chain can be uniformly lubricated. The maximum distance and the minimum distance between the two rotating plates 41 are limited, so that the distance between the rotating plates 41 is not too large and affects the positioning and limiting of the saw chain, and the saw chain is not stuck during the logging process. It should be particularly noted that the maximum distance between the two rotating plates 41 is determined by the top surface of one rotating plate 41 and the bottom surface of the other rotating plate 41, and the two distances obtained are the maximum distance and the minimum distance. The second groove 42 is arranged to provide a mounting position for the rotating structure 3 and to avoid the rotating structure 3, so as to prevent the height of the rotating structure 3 from affecting the overall thickness.
