[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] Reference Figure 1-3 The present embodiment proposes a cable trench digging device, including a frame 3, the frame 3 is fixedly connected to a plurality of support rods 2 arranged in a vertical direction, the bottom ends of the support rods 2 are rotatably connected to walking wheels 1, and the frame 3 is also connected to handrails 8. Through the handrails 8, the frame 3 can be pushed to move under the action of the walking wheels 1.

[0033] In addition, the frame 3 can also be directly connected to a tractor, and the tractor can be used to pull the frame 3 to move. In actual use, the corresponding driving mode can be selected according to different scenarios to drive the frame 3 to move and realize the trenching of the cable trench.

[0034] Fixed rods 25 are connected to both ends of the frame 3, a rotating shaft 23 is fixedly connected between the two fixed rods 25, the rotating shaft 23 is arranged in the horizontal direction, a fixed ring 24 is fixedly connected to the rotating shaft 23, the fixed ring 24 is rotatably connected to a bucket wheel 6, the bucket wheel 6 is fixedly connected to a plurality of buckets 5, a plurality of buckets 5 are arranged in a ring shape, and the bucket 5 is specifically opened at both ends, and the bucket 5 includes an upper opening and a left opening.

[0035] The frame body 3 is also threadedly connected with a lifting rod 4, the fixing rod 25 is slidably connected to the frame body 3, the fixing rod 25 is rotatably connected to the lifting rod 4, and the lifting rod 4 is also threadedly connected with a large nut.

[0036] The fixing rod 25 is always in a sliding connection with the frame body 3. When the lifting rod 4 rotates, it can drive the fixing rod 25 to move in the vertical direction. At the same time, the large nut is set above the frame body 3. When the height of the fixing rod 25 is adjusted, the lifting rod 4 can be auxiliary fixed by tightening the large nut.

[0037] The fixed ring 24 is provided with a discharge space 29, and the discharge space 29 is provided with a feed port 27 and a discharge port 28. The feed port 27 and the discharge port 28 are both arranged above the fixed ring 24, and the bottom surface of the discharge space 29 is an inclined surface, the feed port 27 is higher than the discharge port 28, and the width of the feed port 27 is large enough, so that the soil in the bucket 5 has enough time to be poured into the discharge space 29.

[0038] When the bucket wheel 6 drives the bucket 5 to make a circular motion, the soil can be excavated under the action of the left opening of the bucket 5. At this time, the upper opening and the fixed ring 24 are in contact. When the bucket 5 rotates upward, the upper opening is above the feed port 27. The soil in the bucket 5 can enter the discharge space 29 through the upper opening and the feed port 27.

[0039] The frame 3 is connected to a rotatable conveyor belt 18, and is also connected to a horizontally sliding soil receiving plate 16, which is arranged in an inclined direction, with one end of the soil receiving plate 16 arranged on one side of the discharge port 28, and the other end of the soil receiving plate 16 arranged on one side of the conveyor belt 18.

[0040] The frame 3 is also rotatably connected to a plurality of support rollers, on which the conveyor belt 18 is sleeved, one of which is connected to a second motor 19, which is fixedly connected to the frame 3. The conveyor belt 18 is also fixedly connected to a plurality of receiving plates, with a suitable distance between adjacent receiving plates.

[0041] The receiving plate is arranged on one side of the soil receiving plate 16, and is used to receive the soil on the soil receiving plate 16. When receiving the soil, the receiving plate and the soil receiving plate 16 are parallel to each other. When the conveyor belt 18 rotates, several receiving plates can be driven to rotate at the same time, so that the soil on the receiving plate can be dumped on one side of the groove.

[0042] The middle part of the fixed ring 24 is rotatably connected with the central shaft 21, the central shaft 21 is rotatably connected with the rotating shaft 23, the rotating shaft 23 supports the central shaft 21, the central shaft 21 is fixedly connected with the bucket wheel 6, and pulleys 20 are fixedly provided at both ends of the central shaft 21.

[0043] The frame 3 is fixedly connected with a first motor 7, which is connected with a driving wheel, and a second belt 26 is hung on the driving wheel and the pulley 20. The first motor 7 can drive the driving wheel to rotate, and then drive the pulley 20 to rotate through the second belt 26, thereby driving the bucket wheel 6 to rotate.

[0044] A cleaning roller 17 is rotatably disposed in the discharge space 29 . The cleaning roller 17 is rotatably connected to the fixing rod 25 . A first belt 22 is sleeved on the cleaning roller 17 and the pulley 20 .

[0045] The cleaning roller 17 is disposed at a suitable position of the discharge space 29 , and is used to break up the soil in the discharge space 29 to facilitate the soil to fall from the discharge port 28 .

[0046] The frame 3 is fixedly connected with a sliding plate 9 arranged in a horizontal direction, and the sliding plate 9 is arranged on one side of the conveyor belt 18. The bottom end of the sliding plate 9 is fixedly connected with a slide rail 10, and the slide rail 10 is slidably connected with a slider 11, and the slider 11 is fixedly connected with a vertical rod 15 arranged in a vertical direction, and the vertical rod 15 is fixedly connected with the earth-connecting plate 16. The slide rail 10 is connected with the movement of the earth-connecting plate 16, and plays a role of limiting and guiding, so that the earth-connecting plate 16 can only move in the horizontal direction.

[0047] The frame 3 is rotatably connected to a rotating wheel 12 , and a third belt is sleeved on the rotating wheel 12 and the driving wheel. The rotating wheel 12 is eccentrically rotatably connected to a first connecting rod 13 , and the other end of the first connecting rod 13 is hinged to a second connecting rod 14 , and the other end of the second connecting rod 14 is hinged to a vertical rod 15 .

[0048] The first motor 7 can drive the rotating wheel 12 to rotate through the third belt, and then drive the soil contacting plate 16 to reciprocate in the horizontal direction through the first connecting rod 13 and the second connecting rod 14.

[0049] When the soil receiving plate 16 moves to above or below the receiving plate, the soil receiving plate 16 is located on one side of the bucket 5, and the soil receiving plate 16 will not affect the normal movement of the bucket 5. At the same time, since a part of the soil receiving plate 16 moves above the receiving plate, the soil on the soil receiving plate 16 can fall onto the receiving plate.

[0050] When the soil receiving plate 16 moves to the top or bottom of the bucket 5, the soil receiving plate 16 is located on one side of the receiving plate, and the soil receiving plate 16 will not affect the normal movement of the receiving plate. At the same time, because the soil receiving plate 16 is relatively close to the bucket wheel 6, the soil in the discharge port 28 can fall on the soil receiving plate, which can facilitate the receiving of the soil in the discharge space 29.

[0051] The above work is achieved by reasonably adjusting the distance between adjacent buckets 5 and adjacent receiving plates so that the moving speed of the receiving plate 16 is just matched with the movement of the bucket 5 and the conveyor belt 18.

[0052] The side of the receiving plate can also be connected to a retaining plate, and the retaining plate and the receiving plate cooperate with each other to form a box-like structure. A through hole can be opened at the right end of the receiving plate 16. When the receiving plate 16 moves above the receiving plate, it can fall onto the receiving plate under the action of the through hole.

[0053] Since the through hole is arranged on the right side of the soil receiving plate 16, the soil in the discharge space 29 falls into the left side of the soil receiving plate 16. Therefore, when the soil slides to the right side of the soil receiving plate 16, the soil receiving plate 16 just moves to above the receiving plate. The through hole can facilitate the falling of the soil. As the soil receiving plate 16 moves to the right, the soil can be evenly laid on the receiving plate to prevent the receiving plate from being subjected to force on only one side, which affects its service life.

[0054] The present invention also provides a method for using a cable trench digging device, which uses the cable trench digging device described in this embodiment, including the following steps:

[0055] S1: Push the frame 3 to move, and start the first motor 7 and the second motor 19 at the same time. The first motor 7 drives the middle shaft 21 to rotate through the second belt 26, and then drives the bucket wheel 6 to rotate. At the same time, the second motor 19 drives the conveyor belt 18 to rotate through the support roller;

[0056] S2: The bucket wheel 6 drives the bucket 5 to make a circular motion. Under the action of the bucket 5, the cable trench is excavated. As the bucket 5 moves, when the bucket 5 rotates to one side of the feed port 27, the soil in the bucket 5 enters the discharge space 29;

[0057] S3: Soil falls onto the soil receiving plate 16 through the discharge port 28, and at the same time, the first motor 7 drives the rotating wheel 12 to rotate through the third belt, and the rotating wheel 12 drives the vertical rod 15 to move rightward through the first connecting rod 13 and the second connecting rod 14, and the vertical rod 15 drives the soil receiving plate 16 to move rightward, so that the soil receiving plate 16 moves to one side of the bucket 5, and the soil receiving plate 16 continues to rotate after the bucket 5 jumps over;

[0058] S4: As the rotating wheel 12 continues to rotate, the soil receiving plate 16 moves to above the receiving plate, so that the soil on the soil receiving plate 16 falls onto the receiving plate;

[0059] S5: As the rotating wheel 12 continues to rotate, the soil receiving plate 16 moves to the left, and the soil receiving plate 16 moves to one side of the receiving plate. After the receiving plate jumps over, the soil receiving plate 16 continues to rotate, so that the soil on the receiving plate is dumped to one side of the cable trench;

[0060] S6: As the wheel 12 and the bucket wheel 6 continue to rotate, the bucket wheel 6 drives the bucket 5 to make a circular motion, so that the soil on the bucket 5 falls into the discharge space 29 through the feed port 27, and the soil receiving plate 16 moves to the side of the discharge port 28, so that the soil in the discharge space 29 falls onto the soil receiving plate 16;

[0061] S7: Repeat S2-S6 until the excavation of the cable trench is completed.

[0062] It should be noted that the bucket wheel 6 can drive the bucket 5 to make a circular motion. Under the action of the bucket 5, the trench can be excavated. At the same time, the height of the bucket wheel 6 can be adjusted by rotating the lifting rod 4, so as to realize the excavation of trenches of different depths. A fixing ring 24 is also provided in the bucket wheel 6. The fixing ring 24 has a discharge space 29. With the movement of the bucket 5, the soil in the bucket 5 can enter the discharge space 29 through the feed port 27, and then fall onto the receiving plate 16 through the discharge port 28. The soil on the receiving plate 16 can fall onto the receiving plate of the conveyor belt 18. The conveyor belt 18 can drive the receiving plate to rotate so that the soil on it falls into one side of the trench. In the process of excavating the trench, the soil can be dumped at the same time to prevent the soil from falling into the opened trench, thereby effectively improving the construction efficiency and the quality of trenching.

[0063] In addition, when the wheel 12 rotates, the first connecting rod 13 and the second connecting rod 14 can drive the soil receiving plate 16 to move back and forth in the horizontal direction. When the soil receiving plate 16 moves to the right to the side of the bucket 5, the bucket 5 can jump over the soil receiving plate 16. At this time, the soil receiving plate 16 will not affect the normal movement of the bucket 5. At the same time, the soil receiving plate 16 moves to the side of the receiving plate, so that the soil on the soil receiving plate 16 can fall onto the receiving plate.

[0064] When the soil receiving plate 16 moves to the left to the side of the receiving plate, the conveyor belt 18 can drive the receiving plate to rotate, and the soil receiving plate 16 will not affect the normal rotation of the receiving plate. At the same time, the soil receiving plate 16 moves to the side of the discharge port 28, which is convenient for the soil in the discharge space 29 to fall onto the soil receiving plate 16, which can have a better receiving effect and prevent the soil from falling into the groove, thereby effectively improving the soil receiving efficiency without affecting the normal movement of the bucket wheel 6 and the receiving plate.

[0065] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
