[0044] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0048] In some embodiments of the present invention, Figure 1-2As shown, the soil backfilling device includes a vehicle body 1 and a storage box 2, a trenching assembly 3 and a conveying assembly 4 installed on the vehicle body 1; the storage box 2 is used to store backfill soil; the trenching assembly 3 includes at least one trenching plow 31, which is used to be inserted into the ground and dig a trench; the conveying assembly 4 includes at least one conveying pipe 41, the feed end of the conveying pipe 41 is connected to the storage box 2, and the discharge end of the conveying pipe 41 is located behind the trenching plow 31, and the conveying pipe 41 is used to convey the backfill soil into the trench.

[0049] Specifically, Figure 1 This is a schematic diagram of a soil backfilling device. The vehicle body 1 is set as the body of a tractor, so that the storage box 2 can carry more backfill soil to complete backfill work in a larger area. In addition, the body of the tractor can adapt to different terrains to complete the work and has a wide range of applications.

[0050] Optionally, the backfill soil can be an amendment or treated in-situ soil.

[0051] Optionally, the storage box 2 is configured as a compartment of the tractor, or may be configured as a storage bucket mounted on the vehicle body 1 .

[0052] A plurality of furrowing plows 31 can be arranged in the width direction of the vehicle body 1, and a plurality of trenches can be opened at the same time, thereby improving work efficiency; a conveying component 4 is provided to convey the backfill soil in the storage box 2, and the discharge end of the conveying pipe 41 is located behind the furrowing plow 31. As the vehicle body 1 moves forward, after the furrowing plow 31 opens the trench, the conveying pipe 41 can convey the backfill soil into the trench. A conveying pipe 41 is correspondingly provided for each furrowing plow 31; a conveying mechanism capable of conveying granular or powdery matter, such as an auger, a belt conveying mechanism, a spiral conveying mechanism, a vibrating conveying mechanism, etc., can be installed in the conveying pipe 41 to realize automated arrangement.

[0053] In the prior art, soil backfilling is completely manual, resulting in heavy workload and long working time. In the present invention, the conveying assembly 4 is located behind the trenching assembly 3. As the vehicle body 1 advances, after the trenching assembly 3 has opened a trench, the conveying assembly 4 transports the backfill soil in the storage box 2 into the trench, thus achieving automated arrangement of soil backfilling and improving work efficiency.

[0054] In some embodiments of the present invention, the trenching assembly 3 also includes a mounting frame 32 and a depth driver (not shown); the mounting frame 32 is movably mounted on the vehicle body 1, and the trenching plow 31 is connected to the lower end of the mounting frame 32; the depth driver drives the mounting frame 32 to drive the trenching plow 31 to move in the vertical direction to adjust the depth of the trench.

[0055] Specifically, when the furrowing plow 31 is working, the depth driver drives the furrowing plow 31 to move downward in the vertical direction, and at this time the bottom of the furrowing plow 31 is lower than the bottom of the wheels of the vehicle body 1, ensuring that the furrowing plow 31 can dig a trench on the ground when the vehicle body 1 is moving forward; and during the working process of the furrowing plow 31, the depth driver can be controlled to drive the furrowing plow 31 to move in the vertical direction to adjust the depth of the trench; when the furrowing plow 31 stops working, the depth driver drives the furrowing plow 31 to move upward in the vertical direction, and at this time the bottom of the furrowing plow 31 is higher than the bottom of the wheels of the vehicle body 1, avoiding damage to the furrowing plow 31.

[0056] Optionally, the depth driver may be configured as a hydraulic telescopic cylinder, and the telescopic direction is a vertical direction, so as to drive the furrowing plow 31 to move in the vertical direction.

[0057] In some embodiments of the present invention, a furrowing plow 31 is provided, which includes two furrowing blades 311. The front ends of the two furrowing blades 311 are connected to form a sharp end, and the rear ends of the two furrowing blades 311 extend toward both sides, so that a accommodating cavity 312 is formed between the two furrowing blades 311. The accommodating cavity 312 is a V-shaped space. When the vehicle body 1 moves forward, the sharp end is inserted into the ground to push the surface soil toward both sides. The pushed surface soil is pushed toward the outside of the furrowing blades under the guidance of the two furrowing blades 311, thereby forming a trench on the surface.

[0058] Optionally, the trenching piece 311 is made of alloy steel, which has elasticity to prevent the trenching piece 311 from being damaged by hard objects when trenching, making trenching easier. The two trenching pieces 311 can be an integrally formed structure to ensure the connection strength between the two trenching pieces 311.

[0059] In some embodiments of the present invention, the discharge end of the conveying pipe 41 is configured to at least partially extend into the accommodating chamber 312, and the backfill soil is conveyed into the accommodating chamber 312 through the conveying component 4 and then directly enters the trench, thereby preventing the soil on both sides of the trench from converging into the trench and causing the trench to become smaller.

[0060] In some embodiments of the present invention, the furrowing plow 31 also includes a closing plate 315 for closing the conveying pipe 41. The closing plate 315 is rotatably installed in the accommodating cavity 312. When the furrowing plow 31 is not working, the closing plate 315 can close the conveying pipe 41 to avoid wasting backfill soil.

[0061] Preferably, if Figure 6As shown, the closing plate 315 is connected to the inclined plate 318, which is arranged inclined relative to the closing plate 315. The width of the inclined plate 318 is greater than the width of the closing plate 315. When the conveying pipe 41 pushes the closing plate 315 to open, the opened closing plate 315 is connected to the inclined plate 318 to form an inclined surface with a gradually increasing width from top to bottom. The backfill soil passing through the inclined surface can cover a larger area of ​​land and the spraying is more uniform.

[0062] Furthermore, the closing plate 315 is installed in the accommodating chamber 312 through the rotating shaft, and a torsion spring is also connected between the closing plate 315 and the accommodating chamber 312; when the lower end of the conveying pipe 41 is located above the rotating shaft, the torsion spring pushes the closing plate 315 to block the bottom of the conveying pipe 41; when the furrowing plow 31 is inserted into the ground, the furrowing plow 31 is pushed upward, so that the lower end of the conveying pipe 41 moves to the bottom of the rotating shaft, and the conveying pipe 41 pushes the closing plate 315 to open, and the opened closing plate 315 forms a downward slope, and the backfill soil enters the trench through the slope, which can be dispersed more evenly.

[0063] In some embodiments of the present invention, the furrowing plow 31 also includes a slide rail 313 and a support slider 314; a slide rail 313 is provided on the inner side of each furrowing piece 311, and the two slide rails 313 are arranged opposite to each other. The horizontal distance between the two slide rails 313 gradually decreases from top to bottom, and the two ends of the support slider 314 are respectively slidably connected to the two slide rails 313; a sliding driver (not shown) is connected to the support slider 314, and the sliding driver drives the support slider 314 to slide along the slide rail 313. The support slider 314 can expand the rear ends of the two furrowing pieces 311, so that the space of the accommodating cavity 312 is larger, which is convenient for transporting more backfill soil.

[0064] Specifically, Figure 2 As shown, the lateral distance between the two sides of the rear end of the accommodating cavity 312 gradually decreases from top to bottom, and the two slide rails 313 are respectively arranged on the inner sides of the two trenching pieces 311 and are parallel to the two sides of the rear end of the trenching pieces 311, that is, the lateral distance between the two slide rails 313 also gradually decreases from top to bottom. The structure of the trenching plow 31 with a larger top and a smaller bottom is easier to insert into the ground and more convenient to dig trenches.

[0065] Optionally, in order to prevent the two grooving pieces 311 from affecting the connection strength of the sharp ends after being stretched open multiple times, the front ends of the two grooving pieces 311 can be configured to be rotatably connected.

[0066] As an implementation method, Figure 4 As shown, both ends of the support slider 314 can be connected to the slide rail 313 through sliding bosses 316 , and the sliding bosses 316 and the support slider 314 are integrally formed to ensure the stability of the structure.

[0067] As another embodiment, Figure 2 As shown, the two ends of the support slider 314 are slidably connected to the slide rail 313 through the connecting column 317, and the width of the slide rail 313 is slightly larger than the diameter of the connecting column 317, that is, the connecting column 317 is snapped into the slide rail 313, and there is a certain amount of movable space in the slide rail 313, and it is ensured that the connecting column 317 does not fall off the slide rail 313; when the furrowing plow 31 is squeezed by the soil and rotates or swings, the connecting column 317 can adaptively offset in the slide rail 313 to prevent the connecting column 317 from deformation.

[0068] Furthermore, if Figure 2 As shown, a limiting protrusion 33 can also be provided on the outer peripheral wall of the conveying pipe 41, and a buffer spring 34 is fixedly connected between the limiting protrusion 33 and the upper end of the furrowing piece 311. When the furrowing plow 31 rotates or swings, causing the deformation amplitude of the buffer spring 34 to be inconsistent, the buffer spring 34 can automatically reset.

[0069] The specific working principle of the furrowing plow 31 is that when the trench dug by the furrowing plow 31 is deeper, the furrowing plow 31 needs more downward pressure. The sliding driver drives the support slider 314 to slide downward along the slide rail 313, which can give the furrowing plow 31 a greater downward pressure to prevent the furrowing plow 31 from deforming. At the same time, the support slider 314 slides downward along the slide rail 313 to stretch the rear ends of the two furrowing plates 311, that is, as the support slider slides downward, the angle of the sharp end of the furrowing plate gradually increases, making the space of the accommodating cavity 312 larger; when the trench dug by the furrowing plow 31 is shallow, the sliding driver drives the support slider 314 to slide upward along the slide rail 313. At this time, the furrowing plow 31 is larger at the top and smaller at the bottom, which makes it easier for the furrowing plow 31 to advance on the surface.

[0070] In some embodiments of the present invention, Figure 3 As shown, the delivery pipe 41 includes a first delivery pipe 411 and a second delivery pipe 412. One end of the first delivery pipe 411 is connected to the storage box 2, and the other end is connected to the second delivery pipe 412 through a hose 413. A delivery driver (not shown) is installed in the first delivery pipe 411, and the delivery driver is used to drive the backfill soil through the first delivery pipe 411, the hose 413 and the second delivery pipe 412 into the trench in sequence.

[0071] Specifically, Figure 1 and Figure 3As shown, in order to make the backfill soil transportation smoother, the delivery pipe 41 is provided with a first delivery pipe 411 and a second delivery pipe 412, and the hose 413 is used to connect them in the middle, so that the position of the delivery pipe 41 can be changed more flexibly, and the layout and installation of other structures are convenient; the delivery drive can be a delivery screw, which is used to forcibly transport the backfill soil in the first delivery pipe 411, and the second delivery pipe 412 is set vertically downward or inclined downward, and the backfill soil in the second delivery pipe 412 can be transported to the trench by gravity.

[0072] Alternatively, the hose 413 may be configured as a bellows.

[0073] In some embodiments of the present invention, Figure 1 As shown, the second delivery pipe 412 is further connected to a vibration assembly 5, which is used to drive the second delivery pipe 412 to vibrate so as to shake off the backfill soil.

[0074] Specifically, the vibration assembly 5 may include a vibration rod 51 (see Figure 3 ) and a vibration driver (not shown), the vibration rod 51 is connected to the second delivery pipe 412, and the vibration driver drives the vibration rod 51 to drive the second delivery pipe 412 to vibrate to prevent the second delivery pipe 412 from being blocked.

[0075] In some embodiments of the present invention, the soil backfilling device further comprises a mixing assembly 6 connected to the vehicle body 1, such as Figure 5 As shown, the mixing assembly 6 includes a swing drive (not shown) and a swing member 61 for inserting into the ground surface. The swing member 61 is swingably connected to the vehicle body 1. The swing member 61 is located behind the conveying pipe 41. The swing drive drives the swing member 61 to swing in the width direction of the vehicle body 1 to mix the backfill soil in the trench.

[0076] Specifically, the mixing assembly 6 also includes a swing arm (not shown) and a mixing head (not shown). The swing arm is swingably connected to the vehicle body 1, and the swing drive drives the swing arm to drive the mixing head to swing. As the vehicle body 1 moves forward, the mixing head is inserted into the ground and swings in the width direction of the vehicle body 1, thereby mixing the backfill soil output by the conveying pipe 41 to the trench, so that the backfill soil is laid more evenly.

[0077] Alternatively, as Figure 5 As shown, a swing cross bar 62 can be provided to be swingably connected to the vehicle body 1, and a plurality of swing members 61 corresponding to the furrowing plow 31 can be provided in the width direction of the vehicle body 1. The plurality of swing members 61 are connected to the swing cross bar 62. The swing driver drives the swing cross bar 62 to swing in the width direction of the vehicle body 1, and the swing cross bar 62 then drives the plurality of swing members to swing in the width direction of the vehicle body, thereby improving work efficiency.

[0078] Optionally, the vibration driver can be eliminated and the swing member 61 and the vibration rod 51 can be driven simultaneously by the swing driver. Since the movement amplitudes of the swing member 61 and the vibration rod 51 are different, a linkage structure can be set between the swing driver and the vibration rod 51 to adjust the movement amplitude of the vibration rod.

[0079] In the present invention, the conveying component 4 is located behind the trenching component 3. As the vehicle body 1 moves forward, after the trenching component 3 digs a trench, the conveying component 4 transports the backfill soil in the storage box 2 into the trench, realizing the automated arrangement of soil backfill, reducing manual operation, simplifying operation, and improving work efficiency.

[0080] The above are only the principles and preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several other variations can be made based on the principles of the present invention, which should also be considered as the scope of protection of the present invention.
