[0019] After adopting the above technical scheme, the effect of the present invention is as follows: the automatic drilling device first receives the short material rods after being sawed by the sawing head through the sawing discharge conveying device, and then turns the short material rods horizontally into the cache frame for caching through the horizontal turning mechanism of the horizontal turning cache device; then the horizontal stepping feeding mechanism takes a rod from the material taking station of the cache frame and sends the rod on the cache support station to the drilling support station of the drilling device, and the sliding drill bit assembly of the drilling machine seat moves longitudinally to the rod close to the drilling support station, so that the rod does not move longitudinally but the drill bit assembly moves longitudinally, and after moving into position, the drilling clamping device clamps the rod for convenience of drilling, and after the entire drilling process is completed, the drill bit assembly is reset, and the rod is still in the original position, which is convenient for the drilling discharge device to send out the drilled rod, so that the entire automatic drilling device can realize the lateral transfer of the rod and the automatic drilling of the rod, and the degree of automation is higher. At the same time, since the rod is fed horizontally, space is further saved.

[0020] Since the drilling support seat is vertically lifted and installed on the drilling machine base, and the drilling support seat is driven by the drilling lifting adjustment device, the height of the drilling support roller on the drilling support seat can be adjusted, so that the center of the rod can be adjusted, and finally meet the drilling requirements of rods with different diameters.

The discharge turning shaft on the discharge frame is driven to deflect, so that the bars on the drilling support device are turned onto the discharge buffer platform, which is convenient for caching, thereby ensuring the drilling rhythm. Then the pushing mechanism lifts the bars to the discharge guide slope, and the bars then roll down from the discharge guide slope to be discharged. The drilling discharge device can facilitate the caching of the bars and ensure a sufficient drilling rhythm. At the same time, the bars are discharged after being lifted, which is convenient for connection with other relatively high conveying devices.

[0023] Since an inclined cache step is provided in the middle part of the material blocking baffle, the lifting block includes a lower lifting part and an upper lifting part, and a step is formed between the lower lifting part and the upper lifting part.

At the same time, the leading sizing block can facilitate the front end sizing of the bar during the transportation process before sawing, so as to ensure fixed-length cutting. At the same time, the sliding direction of the sizing slider forms an angle with the transportation direction of the bar. The impact force of the bar hitting the sizing block during the transportation process will generate component forces in two directions, thereby avoiding the sliding cooperation between the sizing slider and the sizing base more reliably. At the same time, the reset elastic member can play a buffering role, further reduce the impact force, and extend the service life. BRIEF DESCRIPTION OF THE DRAWINGS
