[0019] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0020] according to Figure 1-Figure 3 As described above, this embodiment proposes an anti-oxidation HDPE wellbore pipe cutting device, including a machine base 1, which is hollow. Figure 2 As shown, the cross section of the base 1 is concave, and the corresponding base 1 is provided with a mounting opening 2, and the mounting opening 2 corresponds to the recessed position of the base 1. An arc-shaped opening 20 is provided on the base 1 below the mounting opening 2. The arc-shaped opening 20 can play a positioning role when the anti-oxidation HDPE wellbore pipe is placed. A cutting knife 3 is provided on the inner side of the mounting opening 2, and the cutting knife 3 is connected to the base 1 through a driving component, as shown in FIG. Figure 1 and Figure 2As shown in the figure, the driving component includes a fixing frame 16. The cross-section of the fixing frame 16 is in a U shape. The fixing frame 16 is connected to the machine base 1, and a second electric push rod 17 is installed on the fixing frame 16. The second electric push rod 17 is vertically arranged. At the same time, a protective shell is installed at the telescopic end of the second electric push rod 17, and a motor 18 is installed inside the protective shell. The output end of the motor 18 is connected to the cutting knife 3. Therefore, when cutting the antioxidant HDPE wellbore pipe, by starting the motor 18, the motor 18 drives the cutting knife 3 to rotate. Further, the second electric push rod 17 is used to push the cutting knife 3 downward, so as to contact the clamped antioxidant HDPE wellbore pipe and cut it.

[0021] A cutting opening 4 is provided on the machine base 1 below the cutting knife 3. The cutting opening 4 is mainly to prevent the cutting knife 3 from contacting the machine base 1. Correspondingly, the cutting opening 4 communicates with the inner cavity of the machine base 1. A collection shell 5 is installed inside the machine base 1 below the cutting opening 4, and several groups of collection shells 5 are provided. The several groups of collection shells 5 are arranged from top to bottom in sequence. In this embodiment, two groups of collection shells 5 are provided from top to bottom in sequence. Using two groups of collection shells 5 mainly serves a rotation effect. When a group of collection shells 5 is full of collected debris, it can be pulled out by the staff. At this time, the other group of collection shells 5 is used for collection. After it is full, an idle collection shell 5 can be inserted. While ensuring the processing efficiency, the collection amount of a single collection shell 5 is reduced, thereby avoiding the problem that the weight is too large and causing inconvenience for the staff to carry, and reducing the labor intensity of the staff. A partition 19 is provided on one side of the collection shell 5. The partition 19 is vertically arranged and is connected to the machine base 1, thus separating a storage cavity 21, enabling the device to have the function of storing tools. The front end of the storage cavity 21 penetrates the machine base 1.

[0022] A placement opening 6 is installed on the machine base 1 on one side of the collection shell 5. As Figure 2 shown, the placement opening 6 can accommodate all the collection shells 5 to enter and exit. Specifically, the lowermost collection shell 5 is directly connected to the machine base 1, and two symmetrically arranged retaining strips 22 are provided below the other collection shells 5, and the retaining strips 22 are respectively connected to the machine base 1 and the partition 19.

[0023] Clamping components are installed in the installation openings 2 on both sides of the cutting knife 3. The clamping components include two symmetrically arranged arc-shaped clamping plates 12. A clamping cylinder 13 is installed inside the machine base 1 on one side of the arc-shaped clamping plate 12. The telescopic end of the clamping cylinder 13 passes through the machine base 1 and is connected to the arc-shaped clamping plate 12. During operation, the staff places the antioxidant HDPE wellbore pipe at a predetermined position, and then starts the clamping cylinder 13. The clamping cylinder 13 pushes the arc-shaped clamping plate 12 to clamp and fix the antioxidant HDPE wellbore pipe, and then starts the cutting work. Correspondingly, arc-shaped clamping plates 12 are provided on both sides of the cutting knife 3. Compared with the single clamping method, the two-side clamping method has higher stability.

[0024] A limit baffle 7 is provided on one side of the installation opening 2 away from the cutting blade 3. The limit baffle 7 is connected to the machine base 1 through an adjustment component. Figure 1 and Figure 3 As shown, the adjustment component includes a first electric push rod 8, which is horizontally arranged, and its telescopic end faces the side away from the fixed frame 16. A connecting plate 9 is installed on the telescopic end of the first electric push rod 8, and the connecting plate 9 is connected to the limit baffle 7. At the same time, a part of the connecting plate 9 is in contact with the machine base 1. At the same time, an opening 10 is provided on the machine base 1 below the connecting plate 9. The end of the opening 10 away from the fixed frame 16 penetrates the machine base 1. A scale slide rod 11 is provided on the inner side of the opening 10, and the scale slide rod 11 extends out of the opening 10. The corresponding scale slide rod 11 penetrates the connecting plate 9, as shown in FIG. Figure 3 As shown, part of the connecting plate 9 passes through the opening 10. When performing continuous cutting, there is a requirement for the length. Therefore, before work, according to the required cutting length, the first electric push rod 8 is used to push the limit baffle 7 to move, and the corresponding connecting plate 9 also moves accordingly. Therefore, the corresponding scale on the scale slide bar 11 also changes, and the cutting length is judged by its change. After adjusting the position of the limit baffle 7, there is no need to reposition it during subsequent continuous cutting, which greatly improves the efficiency of continuous processing.

[0025] On both sides above the corresponding cutting opening 4, a debris inlet 14 is provided on the machine base 1, and the position of the debris inlet 14 corresponds to the cutting knife 3, and on both sides of the cutting opening 4 away from the debris inlet 14, an assembly opening is provided on the machine base 1, and a hollow net 15 is installed on the inner side of the assembly opening, and the positions of the hollow net 15, the debris inlet 14 and the cutting opening 4 all correspond to the collecting shell 5, thereby facilitating the debris generated during the cutting process to enter the machine base 1 through the provided debris inlet 14, and the debris remaining on the machine base 1 can be cleaned so that it passes through the mesh of the hollow net 15 or the debris inlet 14, enters the machine base 1, and then falls into the collecting shell 5, making it more convenient to clean the entire device, thereby preventing the debris from affecting the surrounding processing environment.
