[0044] Combined with Figures 1-5As shown, an automatic mud loading device for a plugging machine comprises a track 10, a moving part 11, a mud cylinder 12, a mud pushing cylinder, a clamping assembly and an automatic alignment mechanism; the track 10 is arranged below the external conveying port; the moving part 11 is slidably arranged on the track 10, and the end of the moving path of the moving part 11 is spaced apart from the input end of the plugging machine body 1; the mud cylinder 12 is fixedly arranged on the moving part 11, and the output port of the mud cylinder 12 is flush with the input port of the plugging machine body 1; the mud pushing cylinder is arranged on the moving part 11, and the output end of the mud pushing cylinder 13 extends into the mud cylinder 12; the clamping assembly is arranged at the periphery of the output end of the mud cylinder 12, and the working end of the clamping assembly is clamped with the periphery of the output port of the plugging machine body 1; the automatic alignment mechanism is arranged on the inner side of the output port of the mud cylinder 12, and the working end face of the automatic alignment mechanism abuts against the periphery of the input port of the plugging machine body 1, and can be automatically aligned with the input end of the plugging machine body 1.

[0045] In the above scheme, the track 10 is arranged below the external conveying port to guide the sliding of the moving part 11. The moving part 11 slides on the track 10 and can move along a preset path to the vicinity of the input end of the plugging machine body 1. The mud cylinder 12 is fixedly arranged on the moving part 11 and is used to store the mud to be filled. The output port of the mud cylinder 12 is flush with the input port of the plugging machine body 1 to ensure that the mud can smoothly enter the plugging machine body 1. The mud pushing cylinder is arranged on the moving part 11, and its output end extends into the mud cylinder 12. When the mud pushing cylinder is working, its piston rod is pushed forward to push the mud in the mud cylinder 12 out to its output port. The clamping assembly is arranged at the periphery of the output end of the mud cylinder 12, and is used to clamp with the periphery of the output port of the plugging machine body 1 to ensure that the mud will not leak from the gap between the mud cylinder 12 and the plugging machine body 1 during the filling process. The automatic alignment mechanism is arranged on the inner side of the output port of the mud cylinder 12, and its working end face abuts against the peripheral surface of the input port of the plugging machine body 1. When the moving part 11 slides to the preset position, the automatic alignment mechanism starts to work, and automatically aligns the output port of the mud cylinder 12 with the input port of the plugging machine body 1 by adjusting the position and angle of the output port of the mud cylinder 12. This automatic alignment function can ensure that the mud material can be accurately and evenly filled into the plugging machine body 1, which not only reduces the time and labor intensity of manual operation, but also ensures the material filling quality of the plugging machine body 1.

[0046] An upper slide 101 and a lower slide 102 with a height difference under the projection of a plumb bob are arranged on both sides of the track 10 along the sliding path of the moving part 11. The upper slide 101 is located on the side of the track 10 close to the input port of the plugging machine body 1, and the lower slide 102 is arranged on the side of the track 10 close to the external conveying port. The upstream end of the upper slide 101 and the downstream end of the lower slide 102 are arranged in succession; a protrusion structure is arranged in the chamber of the lower slide 102 from the bottom along its length direction, and part of the circumference of the protrusion structure is in sliding contact with the working end face of the moving part 11, so as to drive the moving part 11 to float up and down.

[0047] In the above scheme, the upper slide 101 is located on the side close to the input port of the plugging machine body 1, while the lower slide 102 is located on the side close to the external conveying port, so that the path of the mud cylinder 12 moving from the external conveying port to the input port of the plugging machine body 1 changes from a low position to a high position, and the upstream end of the upper slide 101 and the downstream end of the lower slide 102 are arranged in succession, ensuring that the moving part 11 can smoothly transition from the upper slide 101 to the lower slide 102 without interruption. When the moving part 11 slides on the lower slide 102, the setting of the protrusion mechanism enables the moving part 11 to float up and down, and can drive the mud cylinder 12 installed on the moving part 11 to float up and down together, so that the mud cylinder 12 vibrates relative to the material inside it, and then the material inside the mud cylinder 12 is fully contacted, avoiding the situation that the formed material cannot meet the working requirements of the plugging machine body 1 due to the existence of gaps between the materials.

[0048] Another embodiment of the track 10 in the present application includes a step-like structure with a height difference between the contact portion of the track 10 and the moving member 11 in the vertical direction, and the connection of the step-like structure is arranged in a continuous manner. The end face at the top of the track 10 in a low position is provided with a protrusion structure along its length direction, and part of the circumference of the protrusion structure is in sliding contact with the moving portion of the moving member 11. The protrusion structure includes a high protrusion section 1022 and a low protrusion section 1021, both of which are sine and cosine structures, and the apex of the low protrusion section 1021 is lower than the apex of the high protrusion section 1022.

[0049] In the initial state, the moving part 11 is located in the upstream path of the low protrusion section 1021 on the track 10. When the external input port completes feeding the material to the mud cylinder 12, the moving part 11 drives the mud cylinder 12 to first contact and slide with the low protrusion section 1021, so that the material inside the mud cylinder 12 vibrates for the first time and squeezes out the bubbles between the internal materials; then the moving part 11 continues to move along the track 10 to one side of the plugging machine body 1, and successively contacts and slides with the high protrusion section 1022, so that the vibration of the material inside the mud cylinder 12 is intensified, the material inside the mud cylinder 12 is flattened and compacted, the gaps between the materials are reduced, and the molding quality of the materials is guaranteed to meet the working requirements of the plugging machine body 1.

[0050] The protrusion structure includes a low protrusion section 1021 and a high protrusion section 1022; the longitudinal sections of the low protrusion section 1021 and the high protrusion section 1022 are both sine and cosine structures, and the apex of the low protrusion section 1021 is lower than the apex of the high protrusion section 1022; the low protrusion section 1021 is fixedly arranged on the side of the downhill slide 102 close to the external conveying port; the high protrusion section 1022 is fixedly arranged on the side of the downhill slide 102 close to the input port of the plugging machine body 1, and the downstream end of the high protrusion section 1022 is arranged in parallel with the bottom end face of the downhill slide 102.

[0051] In the above solution, the low protrusion section 1021 is located on the side of the lower slideway 102 close to the external conveying port. When the moving part 11 slides to the low protrusion section 1021 located on the side of the lower slideway 102 close to the external conveying port, the low protrusion section 1021 first buffers and transitions the moving part 11 and the components installed on the moving part 11 and causes slight vibration. Then, when the moving part 11 displaces to the high protrusion section 1022, the vibration intensity between the moving part 11 and the mud cylinder 12 is increased, and the materials inside the mud cylinder 12 are leveled again, thereby ensuring that the materials inside the mud cylinder 12 can fully contact the inside of the mud cylinder 12 while reducing the working pressure of the mud pushing cylinder 13 and ensuring the forming quality of the materials.

[0052] The clamping component includes a rotating rod 20, a clamping arm 21, a pull rod 22 and a pushing cylinder 23; the rotating rod 20 is rotatably arranged on the circumference of the output port of the mud cylinder 12, and the axial length direction of the rotating rod 20 is consistent with the radial direction of the mud cylinder 12; one end of the clamping arm 21 is fixedly connected to the circumference of the rotating rod 20, and the other end of the clamping arm 21 is clamped to the circumference of the input port of the plugging machine body 1; one end of the pull rod 22 has an eccentric structure and is fixedly connected to the rotating rod 20, and the other end extends towards the axis direction of the mud cylinder 12; the pushing cylinder 23 is horizontally arranged on the circumference of the mud cylinder 12, the pushing direction of the output end of the pushing cylinder 23 is consistent with the axis direction of the mud cylinder 12, and the output end of the pushing cylinder 23 is fixedly connected to the end of the pull rod 22 far from the rotating rod 20.

[0053] In the above solution, the rotating rod 20 is rotatably arranged on the circumference of the output port of the mud cylinder 12, and its axial length direction is consistent with the radial direction of the mud cylinder 12, so that the rotating rod 20 can rotate around the axis of the mud cylinder 12. When it is necessary to connect the plugging machine body 1, the pushing cylinder 23 is started, and its output end pushes the pull rod 22 to move towards the axis direction of the mud cylinder 12. Since the pull rod 22 and the rotating rod 20 are connected through an eccentric structure, when the pushing cylinder 23 pushes the pull rod 22 to drive the rotating rod 20 to rotate, the clamping arm 21 moves along with the rotation of the rotating rod 20, thereby realizing the connection or disconnection with the plugging machine body 1. When it is necessary to disconnect the connection, the pushing cylinder 23 works in the reverse direction to pull back the pull rod 22, so that the rotating rod 20 rotates in the reverse direction, so that the clamping arm 21 disengages from the input port of the plugging machine body 1, achieving the improvement of the convenience and efficiency of manual operation.

[0054] A notch 221 is provided at the end of the pull rod 22 far from the rotating rod 20, and the output end of the pushing cylinder 23 passes through the notch 221 and is fixedly connected to the pull rod 22. The length direction of the notch 221 is consistent with the axial length direction of the pull rod 22.

[0055] In the above solution, the output end of the pushing cylinder 23 passes through this notch 221 and is fixedly connected to the pull rod 22. The pushing cylinder 23 does not need to be directly aligned with the end of the pull rod 22, but can adjust its position within a certain range to adapt to different installation conditions or space limitations.

[0056] The automatic alignment mechanism includes a spherical plain bearing 30, a baffle 31, a retaining ring 32 and a spherical connecting joint 33; the spherical plain bearing 30 is fixedly arranged at the output port of the mud cylinder 12; the baffle 31 is fixedly arranged on one side of the spherical plain bearing 30 close to the inside of the mud cylinder 12; the retaining ring 32 is fixedly arranged on one side of the spherical plain bearing 30 away from the inside of the mud cylinder 12, and the peripheral surface of the retaining ring 32 is in interference fit with the inner side surface of the output port of the mud cylinder 12; the spherical connecting joint 33 is fixedly arranged in the middle of the spherical plain bearing 30, and a channel 331 communicating with the inside of the mud cylinder 12 is provided in the middle of the spherical connecting joint 33, and the axis of the channel 331 is horizontally arranged or at an angle with the axis of the mud cylinder 12.

[0057] In the above solution, the spherical plain bearing 30 is fixedly arranged at the output port of the mud cylinder 12, which can allow the whole mud cylinder 12 to rotate and tilt to a certain extent through the spherical plain bearing 30. The baffle 31 is fixedly arranged on one side of the spherical plain bearing 30 close to the inside of the mud cylinder 12 to prevent the spherical plain bearing 30 from being directly impacted or blocked by the mud. The retaining ring 32 is fixedly arranged on one side of the spherical plain bearing 30 away from the inside of the mud cylinder 12, and its peripheral surface is in interference fit with the inner side surface of the output port of the mud cylinder 12. It ensures that the retaining ring 32 closely fits on the port of the mud cylinder 12 to prevent mud leakage, and at the same time provides stable support for the spherical plain bearing 30. The spherical connecting joint 33 is fixedly arranged in the middle of the spherical plain bearing 30, and the channel 331 in the middle allows the mud to flow out from the inside of the mud cylinder 12, and may adapt to different outflow directions through the rotation and tilt of the spherical connecting joint 33.

[0058] When the output port of the mud cylinder 12 is subjected to forces or movements in different directions (for example, due to the vibration of the mud cylinder 12, the uneven distribution of the mud or the change of the external load), the spherical plain bearing 30 and the spherical connecting joint 33 can respond to these changes and rotate or tilt. Due to the interference fit between the retaining ring 32 and the output port of the mud cylinder 12, it ensures that the automatic alignment mechanism can not only respond to external changes, but also maintain a certain stability and controllability.

[0059] The output port of the spherical connecting joint 33 extends to the input port of the stopper machine body 1, and the end surface of the output port of the spherical connecting joint 33 is in inclined transition with its peripheral surface, and an arc-shaped convex block 34 is provided on the inclined surface of the output port of the spherical connecting joint 33, and the peripheral surface of the convex block 34 abuts against the inner side surface of the input port of the stopper machine body 1 and forms a sealing fit.

[0060] In the above solution, the output port of the spherical connecting joint 33 extends to the input port of the stopper machine body 1, ensuring that the mud can flow smoothly from the spherical connecting joint 33 into the stopper machine body 1 without additional transfer or transition components, simplifying the docking process with the stopper machine body 1. The end face of the output port of the spherical connecting joint 33 is inclined and transitioned with its circumferential surface, which not only helps the smooth discharge of the mud, but also provides a better docking angle with the input port of the stopper machine body 1, reducing friction and resistance caused by angle mismatch. The convex block 34 is arranged in an arc structure to form a tight contact with the inner side surface of the input port of the stopper machine body 1, ensuring the continuity and stability of the mud during transmission.

[0061] The various embodiments in this specification are described in a progressive manner. For the same or similar parts between the various embodiments, reference can be made to each other. Each embodiment focuses on the differences from other embodiments.

[0062] The above embodiments are only used to illustrate the technical solutions of the present application, rather than limiting the present application; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
