A covering plate 21 is fixedly connected between the right sides of the front and rear sides of the conductor rack 32. When the covering plate 21 moves to the left, the covering plate 21 can realize burying the soil on the wire pipe. The right side of the upper part of the mounting frame 1 is connected with a spline shaft 31 through a bearing seat. The right side of the upper part of the mounting frame 1 is slidably connected with a sliding shaft 34. There is a damping feeling between the sliding shaft 34 and the mounting frame 1. A mounting roller 3 is placed between the front end of the sliding shaft 34 and the rear end of the spline shaft 31. The operator can put a roll of pipeline on the mounting roller 3. A driving mechanism 4 is arranged between the two wheels 2 on the right side and the mounting frame 1.

[0034] The adjustment mechanism 5 includes a limit frame 51, a screw rod 52 and a guide rod 53, see Figure 1 and Figure 6As shown, a limit frame 51 is installed between the front and rear sides of the upper part of the outer left side surface of the mounting frame 1 by welding, and a screw rod 52 is rotatably connected with the middle of the bottom of the limit frame 51 by a thread, and the bottom end of the screw rod 52 is rotatably connected with the middle of the top left side of the ditching component 33. When the screw rod 52 rotates alternately forward and reverse, the screw rod 52 can drive the ditching component 33 to move up and down, so that the ditching component 33 can be adjusted to a suitable position, and guide rods 53 are slidably connected with the front and rear ends of the lower part of the limit frame 51, and the bottom ends of the guide rods 53 on both sides are fixedly connected to the left side of the top of the ditching component 33. When the ditching component 33 moves, the guide rod 53 can guide the ditching component 33, thereby making the movement of the ditching component 33 more stable.

[0035] Also includes a torsion block 54, see Figure 6 As shown, a torsion block 54 is fixedly connected to the top end of the screw rod 52 .

[0036] First, the operator places the device at the position where trenching is required, pulls the sliding shaft 34 to move backward, and when the sliding shaft 34 moves backward and loses contact with the installation roller 3, the installation roller 3 can be removed from the spline shaft 31, and then a roll of pipeline is put on the installation roller 3. After the installation roller 3 is put on the pipeline, the installation roller 3 is put back on the spline shaft 31, and the sliding shaft 34 is pushed forward to reset. The sliding shaft 34 is reset and inserted into the installation roller 3. The sliding shaft 34 supports the installation roller 3, pulls the head end of the pipeline around the wire frame 32 and fixes it on the ground, and then starts the trenching assembly 3. 3, the twisting adjustment mechanism 5 operates, the adjustment mechanism 5 operates to drive the ditching assembly 33 to move downward, when the ditching assembly 33 moves downward and contacts the ground, the ditching assembly 33 digs a ditch on the ground, the twisting adjustment mechanism 5 is stopped, the driving mechanism 4 is started, the driving mechanism 4 operates to drive the two right wheels 2 to reverse, the two right wheels 2 reverse and drive the mounting frame 1 to move leftward through the left wheel 2, the mounting frame 1 moves leftward and drives the ditching assembly 33 to move leftward through the adjustment mechanism 5, the ditching assembly 33 moves leftward to dig a ditch on the ground, and at the same time, the ditching assembly 33 moves to The left movement drives the conductor frame 32 to move leftward. Since the head end of the pipeline is fixed on the ground, the guide frame 71 moves leftward, which causes the pipeline to be released. The guide frame 71 presses the released pipeline into the trench. The release of the pipeline drives the installation roller 3 to reverse, and the reversal of the installation roller 3 drives the spline shaft 31 to reverse. At the same time, the conductor frame 32 moves leftward and drives the covering plate 21 to move leftward. The covering plate 21 moves leftward to cover the soil on the pipeline. This is repeated to continuously release the pipeline and bury the pipeline in the trench. When the pipeline is released and buried in the trench, the pipeline and the conductor frame 32 are Disengage contact, close the driving mechanism 4, the driving mechanism 4 stops driving the two right wheels 2 to reverse, the two wheels 2 stop driving the mounting frame 1 to move left through the two left wheels 2, the mounting frame 1 stops driving the trenching assembly 33 to move left through the adjusting mechanism 5, the trenching assembly 33 stops driving the guide frame 32 to move left, the guide frame 71 stops driving the covering plate 21 to move left, the trenching assembly 33 is closed, the twisting adjusting mechanism 5 operates to drive the trenching assembly 33 to move upward and reset, the trenching assembly 33 resets and disengages from the ground, and the twisting adjusting mechanism 5 is stopped.

[0037] When the trenching assembly 33 moves downward into the soil, the driving motor 42 is started, and the driving motor 42 drives the right bevel gear 44 to rotate forward, and the right bevel gear 44 rotates forward to drive the left bevel gear 44 to reverse, and the left bevel gear 44 reverses to drive the horizontal shaft 43 to reverse, and the horizontal shaft 43 reverses through the synchronous belt drive to drive the rotating rod 45 to reverse, and the rotating rod 45 reverses to drive the two right wheels 2 to reverse, and the two right wheels 2 reverse to drive the mounting frame 1 to move to the left through the two left wheels 2, so that the trenching assembly 33 moves to the left to trench, and the pipeline is released and buried in the trench. When the pipeline is completely buried in the trench, the driving motor 42 is turned off, and the driving motor 42 stops driving the right bevel gear 44 to rotate forward, and the right bevel gear 44 stops driving the left bevel gear 44 to reverse, and the left bevel gear 44 stops driving the horizontal shaft 43 to reverse, and the horizontal shaft 43 stops driving the rotating rod 45 to reverse through the synchronous belt, and the rotating rod 45 stops driving the two right wheels 2 to reverse, and the two right wheels 2 stop driving the mounting frame 1 to move to the left through the two left wheels 2, and the trenching assembly 33 also stops moving to the left.

[0038] When the device moves to the position where trenching and burying of cables are required, and the trenching assembly 33 is started, the twisting block 54 is twisted to drive the screw rod 52 to rotate forward. Due to the action of the twisting block 54, the operator can more conveniently twist the screw rod 52 to rotate forward. The forward rotation of the screw rod 52 drives the trenching assembly 33 to move downward through the thread. The front and rear guide rods 53 guide the trenching assembly 33. When the trenching assembly 33 moves downward and contacts the ground, the trenching assembly 33 trenches the ground. When the trenching assembly 33 moves downward to a suitable position, the twisting block 54 is stopped to drive the screw rod 52 to rotate forward, the screw rod 52 stops moving downward through the thread, and the screw rod 52 stops driving the trenching assembly 33 to move downward, and trenching of the ground can be started, and the pipeline can be released and buried in the trench. When all the pipelines are buried in the trench and the trenching assembly 33 stops moving to the left, the twisting block 54 is twisted to drive the screw rod 52 to reverse, and the screw rod 52 reverses and moves upward through the thread. The screw rod 52 moves upward to drive the trenching assembly 33 to move upward, and the trenching assembly 33 moves upward to reset and break contact with the ground. The twisting block 54 stops twisting to drive the screw rod 52 to reverse, and the screw rod 52 stops driving the trenching assembly 33 to move upward. Example 2

[0039] On the basis of embodiment 1, a limiting mechanism 6 is further included. The limiting mechanism 6 includes a fixing plate 61, a guide column 62, a limiting wheel 63, a first spring 64, a connecting rod 65 and a vertical rod 66. Figure 1 and Figure 7As shown, a fixing plate 61 is installed in the middle of the front and rear sides of the top of the mounting frame 1 by welding, a guide column 62 is fixedly connected between the left sides of the front and rear fixing plates 61, and a limiting wheel 63 is slidably mounted on the guide column 62. When the pipeline starts to lay out, the limiting wheel 63 can guide the pipeline, and a connecting rod 65 is fixedly connected between the right sides of the front and rear fixing plates 61. The connecting rod 65 passes through the right side of the limiting wheel 63. When the limiting wheel 63 moves, the connecting rod 65 can guide the limiting wheel 63. A first spring 64 is connected between the right side of the outer rear side surface of the limiting wheel 63 and the right side of the front side surface of the rear fixing plate 61. The first spring 64 is sleeved on the connecting rod 65, and vertical rods 66 are fixedly connected to the left sides of the outer front and rear sides of the limiting wheel 63.

[0040] The device further includes a deviation correction mechanism 7, which includes a guide frame 71, a sliding block 72, a second spring 73, a short shaft 74, a rotating rod 75 and a scroll spring 76. Figure 1 , Figure 8 and Fig. 9 When the locking cam 72 is in the unlocked position, the locking cam 73 is in the unlocked position, and the locking cam 73 is in the unlocked position when the locking cam 73 is unlocked.

[0041] When the trenching assembly 33 moves to a suitable position, the pipeline head end is pulled around the limiting wheel 63, and then the pipeline head end is continued to be pulled around the wire rack 32 and fixed on the land. Then, when the pipeline begins to be released and buried in the ditch, since the pipeline is rolled evenly, the pipeline will drive the limiting wheel 63 to move forward and backward during the release of the pipeline. The limiting wheel 63 moves forward and backward so that the first spring 64 is continuously extended and retracted. The limiting wheel 63 moves forward and backward to guide the pipeline, and the limiting wheel 63 moves forward and backward to drive the front and rear side vertical rods 66 to move forward and backward. When the pipeline is fully released and buried in the ditch, the pipeline is disengaged from the limiting wheel 63. Due to the action of the first spring 64, the limiting wheel 63 moves to the original position, and the limiting wheel 63 stops driving the front and rear side vertical rods 66 to move forward and backward. In this way, the pipeline can be better released and pressed into the ditch by the wire rack 32 to complete the buried line.

[0042] When the pipeline is released and buried in the ditch, the limiting wheel 63 drives the front and rear side vertical rods 66 to move forward and backward, and the front side vertical rod 66 moves forward, which means that the pipeline is released from the front side and bypasses the wire rack 32. The pipeline is in an inclined state, and the front side vertical rod 66 moves forward and contacts the front side rotating rod 75. The front side vertical rod 66 drives the front side rotating rod 75 to reverse, and the front side spiral spring 76 is compressed. The front side rotating rod 75 reverses and drives the front side sliding block 72 to move backward. The front side second spring 73 is stretched, and the front side sliding block 72 moves backward and contacts the pipeline. The front side sliding block 72 drives the lower part of the pipeline to move backward. The lower part of the pipeline moves backward and is in a vertical state with the wire rack 32. The wire rack 32 presses the pipeline into the ditch, and when the front side vertical rod 66 moves backward and disengages from the front rotating rod 75, due to the action of the front side spiral spring 76, the front side The forward rotation of the rotating rod 75 does not limit the front sliding block 72. Due to the action of the second front spring 73, the front sliding block 72 moves forward and resets to disengage from the pipeline. Similarly, when the rear vertical rod 66 moves backward and contacts the rear rotating rod 75, it means that the pipeline is released from the rear side to bypass the wire rack 32, and the pipeline is in an inclined state. The rear vertical rod 66 drives the rear rotating rod 75 to rotate forward, the rear spiral spring 76 is compressed, the rear rotating rod 75 rotates forward to drive the rear sliding block 72 to move forward, the rear second spring 73 is compressed, the rear sliding block 72 moves forward and drives the lower part of the pipeline to move forward, which makes the pipeline and the wire rack 32 in a vertical state, and the guide frame 71 presses the pipeline into the groove. Repeat this process, and whenever the pipeline deviates, the pipeline and the wire rack 32 can be pressed into the groove in a vertical state. When the pipeline is fully released and buried in the ditch, the front and rear vertical rods 66 stop moving forward and backward, the front and rear rotating rods 75 stop moving, and the front and rear sliding blocks 72 also stop moving forward and backward. In this way, the pipeline can be prevented from deviating and breaking away from the influence of the conductor frame 32 and being buried in the ditch. Example 3

[0043] On the basis of the embodiment 1 and the embodiment 2, a bulldozer mechanism 8 is also included. The bulldozer mechanism 8 includes a mounting plate 81 and an inclined plate 82. Figure 1 and Fig.10 As shown, a mounting plate 81 is symmetrically fixed to the lower part of the left side of the trenching assembly 33, and an inclined plate 82 is installed on the left side of the front and rear mounting plates 81 by welding. When the inclined plate 82 moves to the left, the inclined plate 82 can push away the excavated soil.

[0044] The self-locking mechanism 9 includes a ratchet 91, a pawl 92 and a torsion spring 93. Figure 1 and Fig.11As shown, a ratchet 91 is fixedly mounted on the front side of the spline shaft 31, and a pawl 92 is rotatably connected to the upper left side of the inner front side surface of the mounting frame 1. The pawl 92 is engaged with the ratchet 91. The pawl 92 can limit the ratchet 91 to prevent the ratchet 91 from rotating forward. A torsion spring 93 is connected between the left side of the front side surface of the pawl 92 and the left side of the upper left side of the inner front side surface of the mounting frame 1.

[0045] When the trenching assembly 33 moves to the left to open trenches, the trenching assembly 33 also drives the front and rear mounting plates 81 to move to the left, and the front and rear mounting plates 81 drive the front and rear inclined plates 82 to move to the left. The front and rear inclined plates 82 move to the left to push the mud generated during the trenching process to both sides. When the trenching assembly 33 stops moving to the left, the trenching assembly 33 stops driving the front and rear inclined plates 82 to move to the left through the front and rear mounting plates 81. In this way, mud can be prevented from affecting the embedding of the pipeline.

[0046] When the pipeline is released, the pipeline drives the installation roller 3 to reverse, the installation roller 3 reverses and drives the spline shaft 31 to reverse, the spline shaft 31 reverses and drives the ratchet 91 to reverse, the ratchet 91 reverses and slides on the pawl 92, when the pipeline is fully released and buried in the trench, the spline shaft 31 stops driving the ratchet 91 to reverse, and the pawl 92 limits the ratchet 91. In this way, the installation roller 3 can be prevented from rotating forward to affect the release.
