[0017] like Figure 1 As shown, a log edge sawing machine includes a feed rack 1 and a chain transmission mechanism 3 for conveying logs. Side limit plates 4 are provided on both sides of the placement plane of the feed rack 1. A rear limit stopper 5 is provided at the rear end of the placement plane of the feed rack 1. A conveying rack 2 is provided at the front end of the feed rack 1. Two chain transmission mechanisms 3 are installed in parallel on the two inner sides of the conveying rack 2. The chain transmission mechanism 3 is arranged to be tilted upward, and the lower end of the chain transmission mechanism is arranged below the placement plane of the feed rack 1. Preferably, the angle between the chain transmission mechanism 3 and the ground is 30-40°. The chain transmission mechanism includes an L-shaped push plate 31 fixed on the transmission chain 31 and a driving mechanism 32 for driving the transmission chain 31 to rotate. A cutting mechanism 7 is provided on the outer side of the middle part of the conveying rack 2. The driving mechanism 32 is composed of a driving sprocket, a driven sprocket, a driving motor, etc., which belongs to an existing mechanism and will not be described in detail here.

[0018] The upper end of the limit contact surface of the rear limit stopper 5 is a downwardly inclined surface. This structure is conducive to the logs falling into the limit area of ​​the placement rack.

[0019] The side limit plates 4 are in a U-shaped structure, and strip-shaped mounting holes 41 are provided on both sides of the top surface of the unloading rack 1. The bottom plate of the side limit plates 4 is provided with corresponding fixing holes, and the side limit plates 4 are fixed by bolts 42 that penetrate the fixing holes and the strip-shaped mounting holes 41. The strip-shaped mounting holes 41 are conducive to adjusting the installation width of the two side limit plates 4. The two side limit plates 4 are larger than the length of the logs by 3-6 cm, which is convenient for the logs to be placed.

[0020] The top surface of the unloading rack 1 is provided with two groups of rollers 6 arranged horizontally in the conveying direction, and the rollers 6 are rotatably mounted on the unloading rack 1 through bearings. By rolling the rollers 6, it is convenient to move the fine-tuning log left and right to reduce the friction of movement.

[0021] A reinforcing diagonal rod 33 is connected between the crossbar and the vertical rod of the L-shaped pushing plate 31. The reinforcing diagonal rod 33 is connected with the crossbar and the vertical rod by welding to play a role of reinforcing support.

[0022] When in use, the logs are hung on the unloading rack 1, and the side limit plates 4 are used to limit the left and right positions to avoid excessive left and right deviations. The rear limit block 5 is used to limit the rear side to prevent rolling during layout. Then, as the transmission chain 31 of the chain transmission mechanism 3 rolls, the L-shaped pushing plate 31 pushes the logs upward from the bottom of the unloading rack 1. After the two ends of the logs are trimmed by the cutting mechanism 7, the logs are unloaded from the upper end of the chain transmission mechanism 3. The sawing machine conveys the logs through the unloading rack and the inclined chain transmission mechanism. It is not limited by the diameter of the logs and can adapt to the conveying and cutting of logs of different diameters. It realizes automatic feeding and discharging, does not require pressing and conveying, has a simple structure, and is easy to use.

[0023] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
