Description

Technical Field

[0001] This invention relates to the field of trenching and laying equipment, and in particular to an integrated machine for trenching open and closed trenches and laying biomass filler pipes. Background Technology

[0002] In traditional agricultural production, large amounts of straw are often discarded or burned after crop harvesting. However, with increased awareness of soil and environmental protection in my country in recent years, people have clearly recognized the beneficial effects and sustainable green development advantages of returning straw to the field. This method not only improves resource utilization efficiency and avoids waste, but also significantly enhances farmland fertility, improves soil temperature and humidity conditions, increases organic matter and nutrients in the soil, and improves soil structure and properties. This helps prevent soil drought and infertility caused by high temperatures, which negatively impact crop growth. However, current straw-returning methods involve spreading shredded straw on the farmland surface and then burying it in the soil using a rotary tiller. Because the shredded straw is in a relatively shallow layer of soil, it can affect the stability of crop roots during subsequent growth. Furthermore, since straw inevitably contains insect eggs and pests, returning shredded straw to the shallow soil layer cannot completely kill these eggs, thus creating a potential source of pests for the following year.

[0003] On the other hand, in the low-lying southern regions where farmland drainage is a major concern, it is usually necessary to lay underground pipes 1.0 to 1.5 meters below the ground to drain rainwater and lower the water table, thus preventing crops from being waterlogged. The process of laying underground pipes requires digging trenches 1.0 to 1.5 meters deep in the farmland soil. Currently, trench digging is done manually, which is not only inefficient but also labor-intensive.

[0004] To address the above problems, a solution is proposed: an integrated machine for trenching (both open and closed), and for laying biomass-filled underground pipes. Summary of the Invention

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Reference Figure 1-13 This invention provides an integrated machine for trenching (both open and closed) and laying biomass-filled underground pipes, comprising: The power assembly includes a power chassis 4, on which an internal combustion engine 6, a gearbox 7, a winch 1 2, and a winch 2 201 are mounted. The internal combustion engine 6 is connected to the gearbox 7 via transmission. Tracks 5 are provided on the power chassis 4. The gearbox 7 is connected to the tracks 5 via transmission. A hydraulic station is connected to the gearbox 7 via transmission. The adjustment assembly includes two main supports 9, which are rotatably connected to the power chassis 4. A tilting cylinder 1 is rotatably connected between the main supports 9 and the power chassis 4. The tilting cylinder 1 is connected to the hydraulic station through a pipeline. A crossbeam 15 is fixedly connected to the two main supports 9. A trenching lifting slide 10 and a feeding lifting slide 11 are slidably connected to the main supports 9. A winch 2 is driven to the trenching lifting slide 10, and a winch 201 is driven to the feeding lifting slide 11. A trenching mechanism is provided on the trenching lifting slide 10, and a feeding mechanism is provided on the feeding lifting slide 11.

[0022] When this device is in use, the internal combustion engine 6 drives the input shaft of the gearbox 7 to rotate via a belt, and then transmits the power to the power chassis 4 after the gearbox 7 changes speed. The power chassis 4 drives the track 5 to rotate, thereby enabling the device to move. The output shaft of the gearbox 7 is connected to the hydraulic station to drive the hydraulic station to work and provide hydraulic power for the device. The winches 1 and 201 rely on the hydraulic station for power. The two main supports 9 are connected together by the cross frame 15. The cross frame 15 is fixed to the main supports 9 with bolts for easy maintenance. The tilting cylinder 1 is used to adjust the angle of the main supports 9 to facilitate trenching and laying of biomass filler pipes. The winch 1 is used to adjust the height of the trenching lifting slide 10 on the main supports 9. The trenching mechanism is used for trenching and can replace manual operation. The winch 201 is used to adjust the position of the feeding lifting slide 11 on the main supports 9 to facilitate laying of biomass filler pipes.

[0023] The scheme is further optimized. The trenching mechanism includes a trenching hydraulic motor 19 and a trenching main shaft 16. The trenching main shaft 16 is rotatably connected to the trenching lifting slide 10. The trenching hydraulic motor 19 is fixedly connected to the trenching lifting slide 10. The output end of the trenching hydraulic motor 19 is fixedly connected to the trenching main shaft 16. A spiral trenching blade 20 is fixedly connected to the outer edge of the trenching main shaft 16. A mudguard 21 is fixedly connected to the trenching lifting slide 10. A conical drill 17 and a spherical trencher 18 are fixedly connected to the trenching main shaft 16. The conical drill 17 and the spherical trencher 18 are fixedly connected. The trenching hydraulic motor 19 is connected to the hydraulic station through a pipeline.

[0024] The trenching hydraulic motor 19 drives the trenching main shaft 16 to rotate. The trenching main shaft 16 drives the spiral trenching blades 20, the conical drill 17, and the spherical trencher 18 to rotate. The conical drill 17 rotates and drills into the soil, thereby driving the spherical trencher 18 and the spiral trenching blades 20 into the soil. The function of the spiral trenching blades 20 is to push the excavated soil upwards through the rotating spiral trenching blades 20, and then discharge the excavated soil to the surface. At the same time, because the soil is discharged by rotation, the soil is thrown outwards under the action of centrifugal force when it is discharged from the surface. The soil will fall back into the excavated open and closed trenches; the function of the mudguard 21 is to prevent the soil from moving backward. In turn, the mudguard 21, together with the front of the spiral trenching blade 20, forms a closed space in the spiral trenching blade 20, so that the spiral trenching blade 20 can push the excavated soil upward; at the same time, the mudguard 21 can seal the rear end of the spiral trenching blade 20 to prevent the excavated soil from being thrown out in all directions after being discharged from the ground. The mudguard 21 prevents the soil from being thrown into the open and closed trenches that have been excavated at the rear end, thus ensuring the trenching depth.

[0025] The feeding mechanism is further optimized by including a feeding hydraulic motor 24, a feeding bin 23, and a biomass discharge pipe 22. The feeding bin 23 and the biomass discharge pipe 22 are fixedly connected to the feeding lifting slide 11. The biomass discharge pipe 22 is connected to the feeding bin 23. The feeding hydraulic motor 24 is fixedly connected to the feeding bin 23. An extruder is fixedly connected to the output end of the feeding hydraulic motor 24. The extruder is located inside the feeding bin 23. The feeding bin 23 has an inlet 29. The feeding hydraulic motor 24 is connected to the hydraulic station through a pipeline.

[0026] The feed inlet 29 is connected to a powder pump (not shown in the figure) to convey biomass powder into the feed inlet 29. The biomass powder enters the feeding hopper 23 through the feed inlet 29. The feeding hydraulic motor 24 drives the extruder to rotate. The biomass powder is formed into a biomass filler tube under the extrusion of the extruder. The biomass filler tube enters the biomass discharge pipe 22 and is laid in the trench through the biomass discharge pipe 22. The bottom end of the biomass discharge pipe 22 is bent backward so that the extruded biomass filler tube is squeezed backward, thereby laying the biomass filler tube in the trench.

[0027] The scheme is further optimized. The conical drill 17 is provided with several soil discharge trenches 26. The spherical trencher 18 includes a lower support plate, several scraper teeth and an upper limit ring. Several scraper teeth are fixedly connected between the lower support plate and the upper limit ring. The lower support plate is fixedly connected to the trenching spindle 16. The conical drill 17 is fixedly connected to the lower support plate.

[0028] The conical drill 17 is conical in shape, and multiple soil discharge grooves 26 are provided on the conical surface of the drill 17. The soil squeezed outward during the rotation of the drill 17 is discharged upward through the soil discharge grooves 26, and then discharged into the spiral ditching blades 20 inside the spherical ditch opener 18 through the soil discharge grooves 26. The soil is then discharged to the ground through the spiral ditching blades 20. The spherical ditch opener 18 consists of a lower support plate, scraper teeth, and upper limit rings. The lower support plate is disc-shaped, and scraper teeth are evenly distributed on the edge of the lower support plate to scrape the soil and thus open the ditch. The top end of the scraper teeth is provided with an upper limit ring to support the top of the scraper teeth and ensure that the scraper teeth are not easily deformed during the ditching process. The middle part of the scraper teeth is bent backward, and a cutting edge is provided on one side of the scraper teeth in the direction of rotation to reduce the resistance of the scraper teeth in scraping the soil.

[0029] The design is further optimized by fixing several scrapers 27 to the edge of the spiral grooving blade 20. The scrapers 27 are bent upwards, and the mudguard 21 is fixedly connected to the two sides with stiffening plates 28.

[0030] The outer edge of the spiral grooving blade 20 is evenly distributed with upward-bent scrapers 27. During the rotation of the spiral grooving blade 20, the scrapers 27 scrape the soil around the spiral grooving blade 20. Thus, the scraping teeth of the spherical grooving device 18 work in conjunction with the scrapers 27 to open the grooves. The ribs 28 compress the soil on both sides of the grooves to prevent the soil on both sides of the grooves from collapsing inward after the grooves are opened. At the same time, the ribs 28 block the soil thrown outwards, preventing the soil thrown out by the spiral grooving blade 20 from entering the grooves. In addition, the ribs 28 can also act as reinforcing ribs to strengthen the structural strength of the mudguard 21 and prevent the mudguard 21 from deforming.

[0031] The further optimized design includes an extruder comprising a spiral extrusion forming shaft 25, with extrusion blades 30 fixedly connected to the outer edge of the spiral extrusion forming shaft 25, and the spiral extrusion forming shaft 25 and extrusion blades 30 located within the feeding hopper 23.

[0032] The feeding hydraulic motor 24 drives the spiral extrusion molding shaft 25 to rotate, which in turn drives the extrusion blades 30 to rotate. The spiral extrusion molding shaft 25 extends into the biomass discharge pipe 22. The spiral extrusion molding shaft 25 is a tapered body, thicker at the top and thinner at the bottom. Spiral extrusion blades 30 are mounted on the spiral extrusion molding shaft 25. The function of the feeding hydraulic motor 24 is to drive the spiral extrusion molding shaft 25 to rotate, which in turn drives the extrusion blades 30 to rotate. Thus, the rotating extrusion blades 30 work in conjunction with the spiral extrusion molding shaft 25, the feeding hopper 23, and the biomass discharge pipe 22. 2. Biomass powder is extruded to the bottom of the biomass feeding pipe and shaped into a biomass filler pipe. Since the spiral extrusion forming shaft 25 is a cone-shaped body with a thicker upper end and a thinner lower end, the upper end of the spiral extrusion forming shaft 25 is located in the feeding hopper 23. The spiral extrusion forming shaft 25 can drive the biomass powder conveyed to the feeding hopper 23 to move downward. The biomass powder conveyed downward enters the narrowed space between the spiral extrusion forming shaft 25 and the biomass feeding pipe 22, thereby compacting the biomass powder and making the formed biomass filler pipe less prone to breakage during the laying process.

[0033] To further optimize the scheme, both winches 1-2 and 201-201 are equipped with steel cables 3. Winch 1-2 is connected to the trenching lifting slide 10 via one of the steel cables 3, and winch 2-201 is connected to the feeding lifting slide 11 via the other steel cable 3.

[0034] Winch 12 pulls the trenching lifting slide 10 up or down via steel cable 3, and winch 201 pulls the feeding lifting slide 11 up or down via steel cable 3.

[0035] The scheme is further optimized by providing several positioning pin holes 12 on the main support 9, and mounting holes on both the trenching lifting slide 10 and the feeding lifting slide 11. Positioning pins 14 are placed in the mounting holes. Electromagnets 13 are fixedly connected to both the trenching lifting slide 10 and the feeding lifting slide 11. The electromagnets 13 are set in accordance with the mounting holes. A spring is set in the mounting hole. One end of the spring is fixedly connected to the electromagnet 13, and the other end of the spring is fixedly connected to the positioning pin 14.

[0036] The main support 9 has an "I" shaped cross-section. Several positioning pin holes 12 are evenly distributed on the main support 9. Electromagnets 13 are installed on the feeding lifting slide 11 and the trenching lifting slide 10 respectively. A return spring is also fitted on the positioning pin 14 to push the positioning pin 14 back to its original position. The function of the electromagnet 13 is to control the insertion and removal of the positioning pin 14 by cooperating with the return spring, so that the positioning pin 14 can be inserted into the positioning pin hole 12 through the return spring. Thus, the feeding lifting slide 11 and the trenching lifting slide 10 are fixed on the main support 9 by the positioning pin 14 cooperating with the positioning pin hole 12, thereby fixing the trenching depth of the trenching mechanism and the feeding depth of the feeding mechanism; or the positioning pin 14 can be pulled out of the positioning pin hole 12 by the electromagnet 13, so that the feeding lifting slide 11 and the trenching lifting slide 10 can slide freely on the main support 9 respectively.

[0037] The scheme is further optimized so that the fixed end of the tilting cylinder 1 is rotatably connected to the power chassis 4, the output end of the tilting cylinder 1 is rotatably connected to the main support 9, and the seat 8 is fixedly connected to the power chassis 4.

[0038] In this embodiment, a pin is rotatably connected between the two main supports 9, the output end of the tilting cylinder 1 is rotatably connected to the pin, and the seat 8 is provided for the operator to sit on.

[0039] The method of using this device is as follows: Start the internal combustion engine 6, which drives the track 5 to rotate through the gearbox 7, and transfer the device to the trenching starting point. After it is moved into place, start the tilting cylinder 1. The tilting cylinder 1 pushes the main support 9 to rotate around the pin shaft and move towards the rear end of the power unit, causing the trenching device and the feeding component to tilt backward. After the main support 9 moves into place, start the trenching hydraulic motor 19 of the trenching device and the feeding hydraulic motor 24 of the feeding component. After the trenching hydraulic motor 19 starts, it drives the conical drill 17, spherical trencher 18, and spiral trenching blades 20 to rotate via the trenching main shaft 16. After the feeding hydraulic motor 24 starts, it drives the extrusion blades 30 to rotate via the spiral extrusion forming shaft 25. The rotating extrusion blades 30, in conjunction with the spiral extrusion forming shaft 25, compress the biomass powder pumped to the feeding hopper 23, forming a biomass packing tube. After the trenching hydraulic motor 19 and the feeding hydraulic motor 24 start respectively, the positioning pin 14 on the trenching lifting slide 10 is pulled out, and the winch 2 corresponding to the trenching device is started to gradually lower the trenching mechanism, causing the rotation... The conical drill 17, in conjunction with the spherical trencher 18, drills into the soil under its own weight. After the conical drill 17 has reached the set depth, the positioning pin 14 is released. Under the action of the return spring, the positioning pin 14 is inserted into the positioning pin hole 12 of the main support 9, fixing the height of the trenching mechanism. After the positioning pin 14 is inserted, the track 5 is started. The track 5 pulls the trenching mechanism forward through the power chassis 4, the main support 9, and the trenching lifting slide 10. During the forward movement of the trenching mechanism, the rotating conical drill 17, the scraping teeth of the spherical trencher 18, and the scraper 27 on the spiral trenching blade 20 scrape the soil in the direction of movement. During the drilling to the set depth and the scraping process, the rotating spiral trenching blade 20, in conjunction with the mudguard 21, pushes the excavated soil to the ground. The soil pushed to the ground is thrown out in all directions (except for the rear end of the mudguard 21) under the action of centrifugal force, thus completing the trenching. During the trenching process, as the trenching device moves forward, the positioning pin 14 on the feeding lifting slide 11 is pulled out, and the winch 201 corresponding to the feeding component is started to lower the feeding component, so that the bottom end of the biomass feeding pipe 22 of the feeding component is inserted into the trench. After insertion, the positioning pin 14 is released to fix the height of the feeding mechanism. After the feeding mechanism is fixed, the biomass filler pipe continuously extruded by the biomass feeding pipe 22 is laid in the excavated trench during the forward movement of the feeding component.

[0040] This invention enables the excavation of open and closed trenches via a trenching mechanism, and the extrusion of biomass filler into underground pipes via a feeding mechanism. The extruded biomass filler pipes can then be laid in the excavated trenches using the trenching device and feeding component. This significantly reduces the labor intensity of manual excavation and installation, effectively improving work efficiency. Furthermore, it effectively increases the organic matter in farmland soil, enhances nutrients, and improves soil structure and properties through landfilling. An adjusting mechanism allows for adjustment of the downward spacing between the trenching device and the feeding component, effectively controlling the trenching and laying depth to ensure it aligns with soil moisture and rainfall. This invention solves the problems of high labor intensity and low efficiency associated with existing trenching and landfilling methods.
