[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] Reference Figure 1 - Figure 3 The utility model provides an embodiment of a wear-resistant saw chain guide with self-lubricating function, comprising a saw body 1, which can provide power for the saw chain 3. This technology is existing technology, so it will not be described in detail. A guide plate 2 is provided on the front side of the saw body 1 for guiding the movement direction of the saw chain 3, ensuring that the saw chain 3 runs along a predetermined trajectory during the cutting process, thereby improving the accuracy and efficiency of sawing. At the same time, it is made of wear-resistant material, which can increase the service life of the guide plate 2. A saw chain 3 is provided on the outside of the guide plate 2, which is the direct execution component of sawing. It contacts the cut object through high-speed rotation and uses the cutting action of the saw teeth to saw the object. A fixed shell 4 is provided on the left side of the guide plate 2. An oil storage tank is opened on the left inner wall of the fixed shell 4 for storing lubricating oil, providing an oil source for the lubricating mechanism, so as to ensure that the saw chain 3 and the guide plate 2 can be fully lubricated during operation, reduce wear and extend the service life. A refueling pipe 8 is provided on the front side of the fixed shell 4, which is convenient for users to add lubricating oil to the oil storage tank in the fixed shell 4 to ensure that the oil level in the oil storage tank is sufficient.

[0026] Further, the inner wall of the fixed shell 4 is provided with a lubricating mechanism, which comprises a transmission assembly and a pressurizing assembly. The pressurizing assembly comprises two groups of stabilizing rods 53, which are used for limiting the movement of the sliding blocks 52, so that they can only move vertically upward and downward. The stabilizing rods 53 are vertically and fixedly connected to the inner wall of the fixed shell 4. The outer side of each stabilizing rod 53 is slidably connected with a sliding block 52, which is used for connecting a piston rod 54 and a rotating disc 51. The rotating disc 51 is slidably arranged on the right inner wall of the sliding block 52 through a protruding column arranged on the left side of the rotating disc 51, so as to drive the sliding block 52 to move up and down reciprocatingly. The piston rod 54 is fixedly connected to the left upper side of the sliding block 52, and is driven by the sliding block 52 to move up and down reciprocatingly, so that the piston rod 54 moves in the piston mode in the inner side of a sliding cylinder 55. The upper inner wall of the fixed shell 4 is fixedly connected with the sliding cylinder 55, which cooperates with an air inlet valve 56 and an air outlet valve 57 to realize the air suction and the lubricating oil discharge, so as to realize the self-lubrication of the saw chain 3 and the guide plate 2, thereby reducing the equipment wear and tear, increasing the service life of the equipment, and improving the sawing efficiency.

[0027] With reference to Figure 2 Figure 4 The upper side of the sliding cylinder 55 is provided with the air inlet valve 56, the air inlet of which is arranged on the outer side of the fixed shell 4, and the air outlet of which is arranged on the inner side of the sliding cylinder 55. When the piston rod 54 moves downward, the pressure in the sliding cylinder 55 decreases, the air inlet valve 56 opens, and the external air enters the sliding cylinder 55. When the piston rod 54 moves upward, the air inlet valve 56 closes, and the air in the sliding cylinder 55 is compressed. The air outlet valve 57 is fixedly connected to the front upper side of the sliding cylinder 55 in a penetrating manner. The air inlet of the air outlet valve 57 is arranged on the inner side of the sliding cylinder 55, and the air outlet thereof is arranged in an oil storage bin on the left side of the fixed shell 4. When the air in the sliding cylinder 55 is compressed to a certain degree, the air outlet valve 57 opens, and the compressed air extrudes the lubricating oil from the oil storage bin through an oil outlet pipe, so as to lubricate the guide plate 2 and the saw chain 3, thereby reducing the equipment wear and tear, increasing the service life of the equipment, and improving the sawing efficiency. The upper piston of the piston rod 54 is connected to the inner wall of the sliding cylinder 55. The rotating disc 51 is arranged on the right inner wall of the sliding block 52, and can synchronously rotate with the gear two 45, so as to realize power transmission.

[0028] With reference to Figure 3 and Figure 4 ​The transmission assembly comprises gear two 45, which rotates under the driving of gear one 44 to drive the rotating disc 51 to make a circular motion and provide power for the pressing assembly. The gear two 45 is rotationally connected to the inner wall of the fixed shell 4, and the rotating disc 51 is fixedly connected to the left side of the gear two 45. The upper side of the gear two 45 is engaged with the gear one 44. The power is transmitted to the gear two 45 through the engagement transmission with the gear two 45, and then the rotating disc 51 is driven to rotate, realizing the conversion of the rotating power of the saw chain 3 into the driving power of the lubricating mechanism. Meanwhile, the gear two 45 and the gear one 44 have different gear numbers, forming a speed reduction effect, so that the rotation of the gear two 45 is slow. The right side of the gear one 44 is fixedly connected with the connecting rod 43, which is used to connect the gear one 44 and the transmission wheel 41, so that the gear one 44 and the transmission wheel 41 rotate synchronously. The connecting rod 43 is rotationally connected to the inner wall of the fixed shell 4, and the transmission wheel 41 is inserted into the right side of the connecting rod 43. The transmission wheel 41 is in contact with the saw chain 3 and rotates under the driving of the saw chain 3, so as to transmit the rotating power of the saw chain 3 to the connecting rod 43 and drive the lubricating mechanism to work.

[0029] With reference to Figure 5 and Figure 6 The transmission wheel 41 is arranged below the saw chain 3. The inner wall of the transmission wheel 41 is slidably connected with the slide rod 42, which is arranged in multiple groups. The slide rod 42 directly contacts with the saw chain 3 and is arranged at the outer periphery of the transmission wheel 41 deviating from the center. Through the sliding function, the impact force can be effectively buffered and dispersed, the influence of the impact force on the transmission wheel 41 is reduced, the stability and reliability of the transmission wheel 41 are improved, and the service life is prolonged. The connecting part of the rotating disc 51 and the slide block 52 is arranged at a position deviating from the center of the rotating disc 51. The rear right side of the fixed shell 4 is provided with an oil outlet pipe. The rear lower part of the guide plate 2 is provided with a through groove 6. The oil outlet pipe is in communication with the inner side of the through groove 6. The extruded lubricating oil can flow through the through groove 6 to the saw chain 3, so as to lubricate the saw chain 3 and the guide plate 2, and reduce the friction.

[0030] With reference to Figure 5 The right side of the guide plate 2 is provided with a disassembly assembly. The disassembly assembly comprises a fastening bolt 71, which is arranged in the inner wall of the transmission wheel 41 and is in threaded connection with the connecting rod 43. The fastening bolt 71 is used to fix the transmission wheel 41 on the connecting rod 43. When the transmission wheel 41 needs to be disassembled, the fastening bolt 71 can be loosened to conveniently remove the transmission wheel 41 from the connecting rod 43, so as to facilitate maintenance, replacement or repair. The right side of the guide plate 2 close to the transmission wheel 41 is provided with a cover plate 72, which protects the transmission wheel 41 and the internal components, prevents dust and sundries from entering, and affects the normal work of the saw chain 3 and the guide plate 2. The cover plate 72 is fixedly installed on the guide plate 2 through the fixing bolt 73. The fixing bolt 73 is arranged in two groups and is used to fixedly fix the cover plate 72 on the guide plate 2, so as to ensure the stability and sealing performance of the cover plate 72.

[0031] Working principle: in use, when the saw chain 3 and the guide plate 2 work, the saw body 1 provides power for the saw chain 3, so that the saw chain 3 rotates at high speed, the saw chain 3 contacts the slide rod 42 on the transmission wheel 41, so that the slide rod 42 slides in the inner wall of the transmission wheel 41, thereby driving the transmission wheel 41 to rotate, the transmission wheel 41 transmits power to the connecting rod 43 through the slide rod 42 in the inner wall, and then the gear one 44 on the right side of the connecting rod 43 rotates.

[0032] The gear one 44 meshes with the gear two 45, and the power is transmitted to the gear two 45. Since the gear two 45 and the gear one 44 have different teeth, a deceleration effect is formed, so that the gear two 45 rotates slowly. The gear two 45 drives the rotating disc 51 to do circular motion, and the rotation of the rotating disc 51 drives the sliding block 52 to reciprocate up and down along the stabilizing rod 53, thereby driving the piston rod 54 to do piston motion in the sliding cylinder 55.

[0033] When the piston rod 54 moves downward, the pressure in the sliding cylinder 55 decreases, the intake valve 56 opens, and the outside air enters the sliding cylinder 55; when the piston rod 54 moves upward, the intake valve 56 closes, and the air in the sliding cylinder 55 is compressed. When the air is compressed to a certain degree, the exhaust valve 57 opens, and the compressed air extrudes the lubricating oil in the oil storage of the fixed shell 4 through the oil outlet pipe. The lubricating oil flows through the through slot 6 at the lower part of the rear side of the guide plate 2 and falls on the saw chain 3 and the guide plate 2, thereby realizing lubrication of them, reducing friction and wear, increasing the service life of the equipment, and improving the sawing efficiency.

[0034] When it is necessary to maintain, replace or repair the saw chain 3 and the guide plate 2, the fixed bolt 73 on the cover plate 72 on the right side of the guide plate 2 can be unscrewed, the cover plate 72 is removed, then the fastening bolt 71 is loosened, and the transmission wheel 41 is removed from the connecting rod 43, so as to maintain or replace.

[0035] The above only describes preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements to some technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
