Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1-4As shown, the bar lifting mechanism includes a base plate 1, a loading plate 101 is provided on the top surface of the base plate 1, and a lifting assembly is provided on one side of the loading plate 101, and the lifting assembly includes two fixing bars 2 respectively fixed on the front side of the loading plate 101 near the left and right sides, a fixing plate 201 is fixed on the front side of the loading plate 101 near the top surface, and the outer wall of the fixing bar 2 is slidingly provided with a first sliding frame 202 and a second sliding frame 203 from top to bottom, and a first lifting plate 204 and a second lifting plate 205 are respectively provided between the two first sliding frames 202 and between the two second sliding frames 203, the second lifting plate 205 is slidingly arranged with the front side of the first lifting plate 204, the first lifting plate 204 is slidingly arranged with the front side of the fixed plate 201, and a material discharge box 213 is fixed on the front side of the loading plate 101.

[0023] like Figure 2-Figure 4 As shown, in this embodiment, the left and right ends of the first lifting plate 204 and the second lifting plate 205 extend to the interior of the first sliding frame 202 and the second sliding frame 203 respectively, and the interior of the first sliding frame 202 and the second sliding frame 203 are rotatably connected with adjusting screws 206, and the two ends of the first lifting plate 204 and the second lifting plate 205 are respectively threadedly connected with four adjusting screws 206. By rotating the adjusting screws 206, the two ends of the first lifting plate 204 and the second lifting plate 205 are respectively threadedly connected with the four adjusting screws 206, thereby adjusting the distance between the fixed plate 201, the first lifting plate 204 and the second lifting plate 205, so that the area that can be accommodated at the top of the first lifting plate 204 and the second lifting plate 205 increases or decreases, so that the diameter of the rod required for lifting and loading can be dynamically adjusted.

[0024] like Figure 2-Figure 4As shown, in this embodiment, a sliding opening 207 is provided on the rear side of the discharge box 213, and an abutment plate 208 is slidably inserted inside the sliding opening 207. A spring 209 is fixed between the front side of the abutment plate 208 and the inner rear side of the sliding opening 207. A plug-in rod 210 is fixed on the front side of the abutment plate 208. The plug-in rod 210 is slidably inserted with the inner rear side of the sliding opening 207, and the spring 209 is movably sleeved with the outer wall of the plug-in rod 210. A first hydraulic rod 211 is fixed on the front side of the loading plate 101, and a push plate 212 is fixed on the top of the telescopic rod of the first hydraulic rod 211. The push plate 212 is fixed to the bottom surface of the second lifting plate 205. During the process of adjusting the distance between the first lifting plate 204 and the second lifting plate 205, due to the front side of the abutment plate 208 and the inner rear side of the sliding opening 207, the A spring 209 is fixed between the two sides, so under the elastic force of the spring 209, the abutment plate 208 is close to the front side of the second lifting plate 205, preventing a large gap from being generated between the discharge box 213 and the front side of the second lifting plate 205, which causes the bar to fall. By starting the first hydraulic rod 211 to drive the push plate 212 to push the second lifting plate 205, the top of the second lifting plate 205 picks up a bar until the top of the second lifting plate 205 is flush with the first lifting plate 204, the bar slides into the top of the first lifting plate 204 under the action of gravity, and then continues to start the first hydraulic rod 211 to drive the first lifting plate 204 and the second lifting plate 205 to be parallel to the top of the fixed plate 201. At this time, the bar slides into the top of the fixed plate 201 under the action of gravity to complete the lifting and loading of the bar.

[0025] like Figure 2-Figure 4 As shown, in this embodiment, the top surface of the base plate 1 is rotatably connected to a second hydraulic rod 3 near the rear side, one end of the telescopic rod of the second hydraulic rod 3 is rotatably connected to the rear side of the loading plate 101, and the bottom end of the loading plate 101 is rotatably connected to the top surface of the base plate 1. The loading plate 101 is rotated by the telescopic movement of the second hydraulic rod 3, so that the loading plate 101 and the discharge box 213 are tilted, ensuring that the rods fall better onto the top surface of the second lifting plate 205 under the action of gravity, so as to lift and load the rods.

[0026] like Figure 2-Figure 4 As shown, in this embodiment, the top surface of the base plate 1 is rotatably connected to two support tubes 4 near the rear side, and a support rod 401 is slidably inserted inside the support tube 4. One end of the telescopic rod of the support rod 401 is rotatably connected to the rear side of the loading plate 101. By arranging the support tube 4 and the support rod 401, the loading plate 101 can be provided with auxiliary support and limiting effects.

[0027] like Figure 2-Figure 4As shown, in this embodiment, a mounting opening 5 is opened on the rear side of the abutment plate 208, and a directional wheel 501 is fixed inside the mounting opening 5. The roller of the directional wheel 501 abuts against the front side of the second lifting plate 205. By providing the directional wheel 501 to replace the abutment plate 208 and abut against the front side of the second lifting plate 205, the friction encountered by the second lifting plate 205 during movement can be reduced, thereby increasing the service life of the device.

[0028] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: in use, by rotating the adjusting screw 206, the two ends of the first lifting plate 204 and the second lifting plate 205 are respectively threadedly connected with the four adjusting screws 206, thereby adjusting the distance between the fixed plate 201, the first lifting plate 204 and the second lifting plate 205, so that the area that can be accommodated at the top of the first lifting plate 204 and the second lifting plate 205 is increased or decreased, thereby dynamically adjusting the diameter of the bar to be lifted and loaded. In the process of adjusting the distance between the first lifting plate 204 and the second lifting plate 205, since the spring 209 is fixed between the front side of the abutment plate 208 and the inner rear side of the sliding port 207, under the elastic force of the spring 209, the abutment plate 208 drives the directional wheel 501 to always abut against the second lifting plate 2 Then, the first hydraulic rod 211 is started again to drive the first lifting plate 204 and the second lifting plate 205 to be parallel with the top of the fixed plate 201. At this time, the bar slides into the top of the fixed plate 201 under the action of gravity to complete the lifting and loading of the bar.

[0029] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
