Description

Technical Field

[0001] This invention relates to the field of camellia oleifera planting technology, specifically a ditching machine for camellia oleifera planting gardens. Background Technology

[0002] Camellia oleifera is a common economic forest species, widely distributed in southern and central my country. As a popular landscaping tree, it boasts a beautiful form and delicate foliage, with dark green leaves that give it high ornamental value. Furthermore, the camellia oleifera tree is one of the main raw materials for extracting camellia oil. Camellia oil is rich in monounsaturated fatty acids and is commonly used in cooking oils and pharmaceuticals. The leaves contain nutrients such as tea polyphenols and can be made into nutritious tea for daily consumption. The seeds are rich in protein, fat, and sugar, and can be used to make various pastries such as camellia oleifera biscuits and cakes. Therefore, the camellia oleifera tree not only has ornamental value but also extremely rich economic value and uses. Promoting the development of the camellia oleifera industry is of great significance for both economic development and ecological protection.

[0003] Because camellia oleifera trees are well adapted to tropical, subtropical, and warm, humid climates, and require suitable soil moisture for growth, they are widely distributed in southern and central my country. However, the south experiences excessive rainfall; too much waterlogging can lead to root hypoxia and rot in camellia oleifera trees. Therefore, when planting camellia oleifera trees, it is necessary to dig trenches between rows of trees. This creates parallel trenches that drain water from the soil, reducing the risk of root dampness, maintaining soil aeration and a good rhizosphere environment. This facilitates the absorption of nutrients and water by the roots, promoting the healthy growth of the camellia oleifera trees.

[0004] In tea gardens planted with camellia oleifera trees, trenching machines are commonly used for trenching. However, when trenching between two rows of tea trees, the cutting soil is turned over to both sides of the trench and piled up. Furthermore, the trenching process itself loosens the soil structure, making the soil piled on the inner walls and sides of the trench more prone to shifting and sliding. This allows rainwater to easily wash the soil from the inner walls and sides of the trench into the trench during the rainy season, reducing its effective capacity and drainage, and increasing the risk of waterlogging to the roots of the camellia oleifera trees. Moreover, the loose soil is more easily washed away by rainwater. On the one hand, the soil on the sides of the trench is washed away, leading to soil depletion; on the other hand, the soil on the inner walls of the trench is washed away, exposing the roots of the camellia oleifera trees to the air, which negatively impacts root growth.

[0005] Furthermore, the soil turning over on both sides of the trench exposes the previously moist soil at the bottom to the top, making it more susceptible to sunlight and wind. This increases the rate of soil moisture evaporation, reducing the soil's water content and thus affecting the growth and development of the camellia oleifera trees. On the other hand, the soil layer rich in organic matter and nutrients at the bottom is exposed to the top, making it more susceptible to sunlight and oxidation, leading to the loss of organic matter and nutrients and affecting the nutrient supply and healthy growth of the camellia oleifera trees.

[0006] In view of this, in order to overcome the above-mentioned technical problems, the present invention proposes a ditching machine for tea gardens planted with camellia trees, which solves the above-mentioned technical problems. Summary of the Invention

This invention utilizes the cooperation between a sliding plate and an extrusion plate, allowing the extrusion plate and rotating rollers to roll and compact the soil on both sides of the trench, while the sliding plate further compacts the soil on both sides of the trench. This improves soil density and stability, reducing loose voids. It not only increases the structural strength of the soil on the inner wall of the trench, preventing the soil on the inner wall and sides from loosening and sliding, but also improves the smoothness of the inner wall of the trench, reducing the erosion and washout of the soil by rainwater.

[0025] The beneficial effects of this invention are as follows:

[0026] 1. This invention utilizes the cooperation between a sliding plate and an extrusion plate to roll and compact the soil on both sides of the trench with the extrusion plate and rotating rollers, while the sliding plate compacts the soil on both sides of the trench. This improves the density and stability of the soil, reduces loose voids, increases the structural strength of the soil on the inner wall of the trench, prevents the soil on the inner wall and sides of the trench from loosening and sliding, improves the flatness of the inner wall of the trench, reduces the scouring and erosion of the soil on both sides by rainwater in the trench, increases the effective capacity and drainage capacity of the trench, reduces the risk of the roots of the camellia oleifera tree being soaked, improves soil fertility, prevents the root system of the camellia oleifera tree from being exposed, and ensures the healthy growth of the camellia oleifera tree.

[0027] 2. This invention uses a tilted sliding plate, creating an angle between the tilted plate and the ground.

This facilitates the sliding plate's movement along the accumulated soil, preventing loose soil from being squeezed through the plate and allowing the soil to pass over the upper surface of the plate. This ensures effective compaction of the accumulated soil on both sides of the trench, enhancing contact and compression between the plate and the soil, and improving the plate's soil-carrying capacity. It also avoids the problem of stones colliding between the plate and the soil. Attached Figure Description

Detailed Implementation

[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0038] like Figures 1 to 7 As shown, the ditching machine for tea gardens planted with camellia trees according to the present invention includes:

[0039] The main body 1, and the cutter head 11 and the wheel 12 below the main body 1;

[0040] A drive motor 13 is installed on one side of the machine body 1; the drive motor 13 is used to drive the cutter head 11 to rotate.

[0041] The machine body 1 has a tray that is rotatably mounted on the lower end of the machine body 1; the drive motor 13 is fixedly mounted on one side of the machine body 1; the drive motor 13 is connected to the cutter head 11 via a helical gear set; a handrail is mounted on the side of the machine body 1 near the drive motor 13; and the machine wheel 12 is mounted on the side of the machine body 1 near the drive motor 13.

[0042] The trenching machine also includes:

[0043] Mounting frame 2; the mounting frame 2 is installed at the lower end of the machine body 1 via a lifting module; the lifting module is used to drive the mounting frame 2 to rise and fall; the mounting frame 2 is located at the end of the machine body 1 away from the drive motor 13; the mounting frame 2 is provided with extrusion plates 21 on both sides; the extrusion plates 21 are installed on the mounting frame 2 via a pressure boosting module; the pressure boosting module is used to push the extrusion plates 21 away from the mounting frame 2; there are two extrusion plates 21; a rotating roller 211 is rotatably connected to the side of the two extrusion plates 21 that are away from each other.

[0044] In one embodiment of the present invention, a rectangular groove 212 is provided on the side of the extrusion plate 21 away from the mounting bracket 2; a sliding plate 22 is slidably connected in the rectangular groove 212; the sliding plate 22 is fixedly connected to the bottom of the rectangular groove 212 by a tension spring 213; the sliding plate 22 is inclined.

[0045] When existing trenching machines dig trenches between two rows of tea trees, the cut soil is turned over to both sides of the trench and piled up. Furthermore, the trenching process itself causes the soil to become loose and fragmented, making the soil piled on the inner walls and sides of the trench more prone to shifting and sliding. This allows rainwater to easily wash the soil from the inner walls and sides of the trench into the trench during the rainy season, reducing its effective capacity and drainage, and increasing the risk of waterlogging to the roots of the tea trees. Moreover, the loose soil is more easily washed away by rainwater. On the one hand, the soil on the sides of the trench is washed away, leading to soil depletion; on the other hand, the soil on the inner walls of the trench is washed away, exposing the roots of the tea trees to the air, which negatively impacts root growth.

[0046] During operation, the user places the machine on the ground, allowing the machine body 1 to be supported on the ground by the wheel jaw cutter head 11. First, the lifting module is controlled to raise the mounting frame 2, and then the drive motor 13 is controlled to run. Initially, the cutter head 11 is mounted on the lower end of the machine body 1 via a mounting shaft. The mounting shaft and drive motor 13 are driven by a helical gear set, allowing the drive motor 13 to drive the mounting shaft to rotate, which in turn drives the cutter head 11 to rotate. Since the cutter head 11 is in contact with the ground, it cuts the soil. Furthermore, the blades on the cutter head 11 are curved, allowing the curved blades to flip the cut soil towards both sides of the cut trench. The user moves the machine body 1 backward by holding the handle, causing the machine body 1 to move on the ground via the wheels, while the cutter head 11 cuts along the path of the wheels. When the machine body 1 moves the mounting frame 2 to the groove opened by the cutter head 11, the control lifting module moves the mounting frame 2 downward, allowing the mounting frame 2 to move the extrusion plate 21 into the groove. As the two extrusion plates 21 are squeezed into the groove, the extrusion plates 21 drive the rotating rollers 211 on both sides into the groove and contact the inner wall of the groove. At this time, the sliding plate 22 contacts the soil that has been turned over at the top of the groove. As the extrusion plates 21 continue to enter the groove, the extrusion plates 21 drive the rotating rollers 211 to squeeze the loose soil on both sides of the groove. Supported by the overturned soil, the plate 22 slides upward relative to the extrusion plate 21, causing the slide plate 22 to pull the tension spring 213 upward. At this time, the slide plate 22 is pulled by the restoring force of the tension spring 213, compacting the soil below it until the lower end of the extrusion plate 21 contacts the lower end face of the trench. At this time, the user continues to pull the motor 1 to move the cutter head 11, causing the cutter head 11 to cut the trench. The extrusion plate 21, located behind the cutter head 11, moves synchronously with the cutter head 11, allowing the extrusion plate 21 to drive the rotating roller 211 to rotate along the trench wall. The rotating roller 211 rolls against the trench wall, increasing the compaction effect of the extrusion plate 21 on the soil on the side wall of the trench. At this time, the slide plate 22 is above the trench. The soil above the trench is compacted. Due to the inclined setting of the slide plate 22, an angle is formed between the inclined slide plate 22 and the ground. At this time, the soil on both sides of the trench will enter from the end of the slide plate 22 away from the ground and be continuously compacted by the pressure of the inclined lower end of the slide plate 22. This makes it easier for the slide plate 22 to slide along the overturned and accumulated soil, preventing the excessively loose soil pile from being squeezed by the slide plate 22 and passing through it. The soil passes over the upper end of the slide plate 22, ensuring that the slide plate 22 effectively compacts the overturned and accumulated soil on both sides of the trench, enhances the contact between the slide plate 22 and the soil and generates a squeezing effect, improves the soil-carrying capacity of the slide plate 22, and also avoids the problem of stones colliding between the slide plate 22 and the soil.Moreover, compacted soil not only resists rainwater erosion and washes away, but also increases soil density. On the one hand, this slows down the evaporation of soil moisture when exposed to sunlight and wind, increasing soil moisture content and benefiting the growth and development of camellia trees. On the other hand, compacted soil reduces the gaps between soil particles, thereby reducing air entry and oxidation of organic matter and nutrients, thus increasing soil organic matter and nutrient content, improving nutrient supply and healthy growth of camellia trees.

[0047] This invention utilizes the cooperation between the sliding plate 22 and the extrusion plate 21 to roll and compact the soil on both sides of the trench with the extrusion plate 21 and the rotating roller 211, while the sliding plate 22 compacts the soil on both sides of the trench. This improves the density and stability of the soil, reduces loose voids, increases the structural strength of the soil on the inner wall of the trench, prevents the soil on the inner wall and sides of the trench from loosening and sliding, improves the flatness of the inner wall of the trench, reduces the scouring and erosion of the soil on both sides by rainwater in the trench, increases the effective capacity and drainage capacity of the trench, reduces the risk of the roots of the camellia oleifera tree being soaked, improves soil fertility, prevents the roots of the camellia oleifera tree from being exposed, and ensures the healthy growth of the camellia oleifera tree.

[0048] In one embodiment of the present invention, an annular groove 214 is provided in the extrusion plate 21; the annular groove 214 is connected to the rectangular groove 212; a baffle 215 made of PTFE material is slidably connected in the annular groove 214; the baffle 215 is fixedly connected to the slide plate 22.

[0049] In one embodiment of the present invention, a bulldozer roller 221 is rotatably connected to the lower end of the slide plate 22; a threaded plate 222 is fixedly connected to the surface of the bulldozer roller 221.

[0050] During operation, by setting baffles 215, when the slide plate 22 is blocked by the soil on both sides of the trench and rises relative to the compression plate 21, the baffles 215 can rise synchronously with the slide plate 22. This causes the baffle above the slide plate 22 to be pushed into the annular groove 214 by the slide plate 22, while the baffle below the slide plate 22 extends out of the annular groove 214 under the pull of the slide plate 22. This ensures that the baffles continuously block the rectangular groove 212, preventing soil from entering and clogging the rectangular groove 212, and ensuring that the slide plate 22 can move freely within the rectangular groove. Effective sliding occurs within 212. By making the baffle 215 of PTFE material, it becomes smooth, corrosion-resistant, and wear-resistant, preventing soil from adhering to its surface and thus reducing soil corrosion and wear, thereby extending its service life. The bulldozer roller 221 moves synchronously under the drive of the slide plate 22, allowing it to move across the soil. The loose soil on both sides of the trench increases the contact area between the rotating roller 211 and the soil. Furthermore, the soil, containing moisture after being turned out of the trench, adheres to the surface of the rotating roller 211, increasing its micro-roughness and friction. The moisture also alters the structure and arrangement of soil particles, making them more easily locked together to form a strong structure, further enhancing the friction between the rotating roller 211 and the soil. This friction causes the bulldozer roller 221 to roll, driving the threaded disc 222 to rotate. The rotating disc 222 then pushes the soil away from the trench, preventing the compressed soil from falling back into the trench and increasing the contact area between the sliding plate 22 and the soil. This prevents the soil around the mound from being uncompacted due to soil buildup, thus improving the compaction effect of the sliding plate 22 and effectively enhancing the practical application of the invention.

[0051] In one embodiment of the present invention, the lifting module includes:

[0052] The rack 23 has a groove 14 at its lower end; the mounting bracket 2 is slidably connected to the groove 14; the inner wall of the mounting bracket 2 has a sliding groove 231; the rack 23 is slidably connected to the sliding groove 231; the rack 23 and the bottom of the sliding groove 231 are fixedly connected by a connecting spring 232; an electromagnetic strip 233 is fixedly connected to the bottom of the sliding groove 231; a spur gear 15 is fixedly connected to the surface of the output shaft of the drive motor 13; the spur gear 15 meshes with the rack 23.

[0053] A fixing unit is installed in the groove 14; the fixing unit is used to fix the mounting bracket 2 in the groove 14.

[0054] In one embodiment of the present invention, the fixing unit includes a slot 24; a rod 241 is slidably connected in the slot 24; a groove 242 that mates with the rod 241 is provided on the inner wall of the groove 14; the rod 241 is fixedly connected to the bottom of the groove of the slot 24 by a fixing spring 243; and the rod 241 is fixedly connected to the rack 23 by a steel wire rope 25.

[0055] During operation, initially, the electromagnetic strip 233 is energized. At this time, the electromagnetic strip 233 generates a magnetic force on the rack 23, attracting it and pressing the connecting spring 232 into the slide groove 231. The rack 23 is currently separated from the spur gear 15. When the lifting module needs to drive the mounting frame 2 to lift, the electromagnetic strip 233 is de-energized, freeing the rack 23 from the attraction force. Under the restoring force of the connecting spring 232, the rack 23 extends out of the slide groove 231 and moves closer to the spur gear 15. This causes the rack 23 to pull the insertion rod 241 via the wire rope 25, pressing the fixing spring 243 and extending it out of the slot 24. 2. The rod 241 is inserted into the slot 24 until the rack 23 meshes with the spur gear 15. At this point, the mounting bracket 2 is fully inserted into the slot 24, and the mounting bracket 2 separates from the body 1. Since the drive motor 13 is not running, its output shaft is locked. At this time, the spur gear 15, through its meshing with the rack 23, supports the mounting bracket 2 and prevents it from falling out of the groove 14. If the mounting bracket 2 needs to rise, the drive motor 13 is controlled to rotate, allowing it to drive the spur gear 15 to rotate and mesh with the rack 23. Because the drive motor 13 is fixed to the body 1, its position remains unchanged, allowing it to connect to the rack 23. Since the position of the spur gear 15 remains unchanged, the spur gear 15 pushes the tooth groove of the rack 23 through the teeth 263, thereby driving the rack 23 to rise. This causes the rack 23, which is slidably connected in the slide groove 231, to push the mounting bracket 2 to rise by pushing the upper wall of the slide groove 231. This allows the mounting bracket 2 to move into the groove 14, causing the mounting bracket 2 to move synchronously with the insertion rod 241. Since the groove 14 has multiple slots 242, the insertion rod 241 can pass over the lower slot 242 to the upper slot 242 when it rises. When the insertion rod 241 is aligned with the slot 242, the electromagnet 265 is energized, causing the rack 23 to continuously move away from the spur gear. 15. This loosens the wire rope 25 between the rack 23 and the insert rod 241. At this time, the insert rod 241 enters the slot 242 under the restoring force of the fixed spring 243. At this time, the rack 23 has not yet separated from the spur gear 15. As the insert rod 241 continues to enter the slot 242, the rack 23 begins to separate from the spur gear 15 and moves away from the spur gear 15 into the slide groove 231 until the insert rod 241 is fully in the slot 242. At this time, the rack 23 is fully inside the slide groove 231. Similarly, when it is necessary to adjust the descent of the mounting frame 2, the spur gear 15 and the rack 23 are engaged, and the drive motor 13 is controlled to rotate in the opposite direction, so that the mounting frame 2 can be lowered.

[0056] In one embodiment of the present invention, the booster module includes:

[0057] Screw 26; the screw 26 is rotatably connected to the mounting bracket 2; the threads at both ends of the screw 26 are arranged in opposite directions, and the two ends of the screw 26 are helically connected to sleeve columns 261; the end of the sleeve column 261 away from the screw 26 is fixedly connected to the extrusion plate 21; the sleeve column 261 is slidably connected to the mounting bracket 2;

[0058] A connecting unit is mounted on the mounting bracket 2; the connecting unit is used to connect the drive motor 13 and the screw 26.

[0059] In one embodiment of the present invention, the connecting unit includes a worm gear 16; the worm gear 16 is fixedly connected to the output shaft of the drive motor 13; a strip groove 262 is formed on the outer wall of the screw 26; teeth 263 are slidably connected in the strip groove 262; a magnetic sheet 264 is fixedly connected to one end of the teeth 263 near the bottom of the strip groove 262; an electromagnet 265 is fixedly connected to the bottom of the strip groove 262.

[0060] During operation, due to the different ages of camellia trees, the width and depth of their root systems vary. Therefore, when trenching camellia trees of different ages, the trenching machine often changes the blades to alter the width and depth of the trench. Initially, the teeth 263 are attracted to the bottom of the groove 262 by the magnetic plate 264, ensuring that the teeth 263 are completely within the groove 262. When a larger blade is used, the width and depth of the trench will increase. At this point, the mounting frame 2 is raised by engaging the spur gear 15 and the rack 23, causing the mounting frame 2 to drive the screw 26 and the sleeve to rise until the mounting frame 2 is fully inserted into the groove 14. At this point, the mounting frame 2 drives the screw 26 below the worm gear 16, and the spur gear 15 and the rack 23... Separation occurs when electromagnet 265 is energized, aligning its magnetic poles with those of magnetic plate 264. Based on the principle of like poles repelling, the magnetic plate 264 is pushed by the repulsive force of electromagnet 265, causing tooth 263 to extend out of slot 262. At this point, the tooth 263 closest to worm 16 is blocked by worm 16 and cannot extend. When adjusting the distance between the two pressing plates 21, drive motor 13 rotates, causing worm 16 to rotate. This allows the blades of worm 16 to slide along the upper surface of tooth 263. When the blades of worm 16 blocking tooth 263's extension pass over tooth 263, tooth 263 extends out of slot 262 under the push of magnetic plate 264. The tooth 263 enters between the two blades, causing the worm 16 to mesh with the screw 26 through the tooth 263. The rotating worm 16 then drives the screw 26 to rotate via the tooth 263, causing the screw 26 to rotate relative to the sleeve column 261. Since the sleeve column 261 is helically connected to the screw 26 and slidably connected to the mounting bracket 2, the screw 26 rotates relative to the sleeve column 261 and continuously extends out of the sleeve column 261. This causes the sleeve column 261 to continuously move away from the screw 26, allowing the sleeve columns 261 at both ends of the screw 26 to push the extrusion plates 21 away from each other until the extrusion plates 21 reach the desired position, at which point the electromagnet 26 is controlled. 5. Power is cut off, causing the tooth 263 to enter the strip groove 262 under the drive of the magnetic plate 264. At this time, the user first pulls the motor body 1 to drive the cutter head 11 to open a trench on the ground. When the extrusion plate 21 is above the trench, the spur gear 15 and the rack 23 are controlled to mesh, so that the user drives the mounting frame 2 to descend by driving the spur gear 15, so that the extrusion plate 21 descends to the bottom of the trench. At this time, the user continues to open the trench, so that the extrusion plate 21 can compact the soil on the inner wall of the trench with different widths and depths. The extrusion plate 21 can also be adjusted to increase the extrusion force on the inner wall of the trench, thereby improving the compaction effect of the extrusion plate 21 on the soil on the inner wall of the trench, and further improving the practicality of the invention.

[0061] The specific workflow is as follows:

[0062] During operation, the user places the machine on the ground, allowing the machine body 1 to be supported on the ground by the wheel jaw cutter head 11. First, the lifting module is controlled to raise the mounting frame 2, and then the drive motor 13 is controlled to run. Initially, the cutter head 11 is mounted on the lower end of the machine body 1 via a mounting shaft. The mounting shaft and drive motor 13 are driven by a helical gear set, allowing the drive motor 13 to drive the mounting shaft to rotate, which in turn drives the cutter head 11 to rotate. Since the cutter head 11 is in contact with the ground, it cuts the soil. Furthermore, the blades on the cutter head 11 are curved, allowing them to push the cut soil towards both sides of the created trench. The machine body 1 is flipped; at this time, the user pulls the machine body 1 backward by holding the handle, so that the machine body 1 moves on the ground by the wheels, and the cutter head 11 cuts along the path of the wheels; when the machine body 1 moves the mounting frame 2 to the groove opened by the cutter head 11, the control lifting module moves the mounting frame 2 down, so that the mounting frame 2 can move the extrusion plate 21 into the groove. As the two extrusion plates 21 are squeezed into the groove, the extrusion plates 21 drive the rotating rollers 211 on both sides into the groove and contact the inner wall of the groove. At this time, the slide plate 22 contacts the soil that is flipped at the top of the groove. As the extrusion plates 21 continue to enter the groove, the extrusion plates 21 drive the rotating rollers 211 to squeeze the loose soil on both sides of the groove. Supported by the overturned soil, the slide plate 22 slides upward relative to the extrusion plate 21, causing the slide plate 22 to pull the tension spring 213 upward. At this time, the slide plate 22 is pulled by the restoring force of the tension spring 213, and the soil below it is compacted until the lower end of the extrusion plate 21 contacts the lower end face of the trench. At this time, the user continues to pull the motor 1 to move the cutter head 11, so that the cutter head 11 cuts the trench. The extrusion plate 21, located behind the cutter head 11, moves synchronously with the cutter head 11, so that the extrusion plate 21 can drive the rotating roller 211 to rotate along the trench wall, so that the rotating roller 211 rolls the trench wall, increasing the compaction effect of the extrusion plate 21 on the soil on the side wall of the trench. At this time, the slide plate 22 is above the trench. The soil above the trench is compacted. Due to the inclined setting of the slide plate 22, an angle is formed between the inclined slide plate 22 and the ground. At this time, the soil on both sides of the trench will enter from the end of the slide plate 22 away from the ground and be continuously compacted by the pressure of the inclined lower end of the slide plate 22. This makes it easier for the slide plate 22 to slide along the overturned and accumulated soil, preventing the overly loose soil pile from being squeezed by the slide plate 22 and passing through it. The soil passes over the upper end of the slide plate 22, ensuring that the slide plate 22 effectively compacts the overturned and accumulated soil on both sides of the trench, enhances the contact between the slide plate 22 and the soil and generates a squeezing effect, improves the soil-carrying capacity of the slide plate 22, and also avoids the problem of stones colliding between the slide plate 22 and the soil.Moreover, compacted soil not only resists rainwater erosion and washes away, but also increases soil density. On the one hand, this slows down the evaporation of soil moisture when exposed to sunlight and wind, increasing soil moisture content and benefiting the growth and development of camellia trees. On the other hand, compacted soil reduces the gaps between soil particles, thereby reducing air entry and oxidation of organic matter and nutrients, thus increasing soil organic matter and nutrient content, improving nutrient supply and healthy growth of camellia trees.

[0063] Specifically, by setting baffles 215, when the sliding plate 22 rises relative to the compression plate 21 due to the obstruction of the soil on both sides of the trench, the baffles 215 can rise synchronously under the action of the sliding plate 22. This causes the baffle above the sliding plate 22 to be pushed into the annular groove 214 by the sliding plate 22, while the baffle below the sliding plate 22 extends out of the annular groove 214 under the pull of the sliding plate 22. This ensures that the baffles continuously block the rectangular groove 212, preventing soil from entering and clogging the rectangular groove 212, and ensuring that the sliding plate 22 can move freely within the rectangular groove. Effective sliding occurs within 212. By making the baffle 215 of PTFE material, it becomes smooth, corrosion-resistant, and wear-resistant, preventing soil from adhering to its surface and thus reducing soil corrosion and wear, thereby extending its service life. The bulldozer roller 221 moves synchronously under the drive of the slide plate 22, allowing it to move across the soil. The loose soil on both sides of the trench increases the contact area between the rotating roller 211 and the soil. Furthermore, the soil, containing moisture after being turned out of the trench, adheres to the surface of the rotating roller 211, increasing its micro-roughness and friction. The moisture also alters the structure and arrangement of soil particles, making them more easily locked together to form a strong structure, further enhancing the friction between the rotating roller 211 and the soil. This friction causes the bulldozer roller 221 to roll, driving the threaded disc 222 to rotate. The rotating disc 222 then pushes the soil away from the trench, preventing the compressed soil from falling back into the trench and increasing the contact area between the sliding plate 22 and the soil. This prevents the soil around the mound from being uncompacted due to the presence of soil piles, thus improving the compaction effect of the sliding plate 22 and effectively enhancing the practical application of the invention.Initially, the electromagnetic strip 233 is energized, generating a magnetic force on the rack 23 and attracting it, which in turn presses against the connecting spring 232, causing the rack 23 to enter the slide groove 231. At this point, the rack 23 is separated from the spur gear 15. When the lifting module needs to drive the mounting frame 2 to lift, the electromagnetic strip 233 is de-energized, freeing the rack 23 from the attraction force of the electromagnetic strip 233. Driven by the restoring force of the connecting spring 232, the rack 23 extends out of the slide groove 231 and moves closer to the spur gear 15. This causes the rack 23 to pull the insertion rod 241 via the wire rope 25, pressing the fixing spring 243 out of the slot 242 and into the slot 24, until the rack 23 engages with the spur gear 15, at which point the insertion rod 241 is fully engaged. When the mounting bracket 2 is inserted into slot 24, it separates from the body 1. Since the drive motor 13 is not running, its output shaft is locked. At this time, the spur gear 15 supports the mounting bracket 2 through the rack 23 it meshes with, preventing it from falling out of the groove 14. If the mounting bracket 2 needs to rise, the drive motor 13 is controlled to rotate, so that the drive motor 13 can drive the spur gear 15 to rotate, allowing the spur gear 15 to mesh with the rack 23 for transmission. Since the drive motor 13 is fixed to the body 1, its position remains unchanged, so the position of the spur gear 15 connected to it remains unchanged. Therefore, the spur gear 15 pushes the tooth groove of the rack 23 through the teeth 263 to drive the rack 23 to rise, so that the rack 23, which is slidably connected in the slide groove 231, can rise. The mounting bracket 2 is pushed upward by pushing the upper wall of the slide 231, allowing it to move into the groove 14. This causes the mounting bracket 2 to move the insertion rod 241 synchronously. Since the groove 14 has multiple slots 242, the insertion rod 241 can pass over the lower slot 242 to the upper slot 242 as it rises, until the insertion rod 241 is aligned with the slot 242. At this point, the electromagnet 265 is energized, causing the rack 23 to move away from the spur gear 15. This loosens the wire rope 25 between the rack 23 and the insertion rod 241. The insertion rod 241 then enters the slot 242 under the restoring force of the fixing spring 243. At this point, the rack 23 has not yet separated from the spur gear 15. As the insertion rod 241 continues to enter the slot 242... The rack 23 separates from the spur gear 15 and moves away from the spur gear 15 into the slide groove 231 until the insert rod 241 is fully inserted into the slot 242. At this time, the rack 23 is fully inserted into the slide groove 231. Similarly, when it is necessary to adjust the descent of the mounting frame 2, the spur gear 15 and the rack 23 are meshed, and the drive motor 13 is controlled to rotate in the opposite direction, so that the mounting frame 2 can be lowered. Since the age of the camellia trees is different, the width of their root system and the depth of their root penetration are also different. Therefore, when the trenching machine is trenching camellia trees of different ages, the blades are often changed to change the width and depth of the trench. In the initial state, the teeth 263 are attracted to the bottom of the strip groove 262 by the magnetic sheet 264, so that the teeth 263 are completely located in the strip groove 262.When replacing with a larger blade model, the width and depth of the groove will increase. In this case, the mounting bracket 2 is first raised by engaging the spur gear 15 and rack 23, causing the mounting bracket 2 to drive the screw 26 and sleeve upwards until the mounting bracket 2 is fully inserted into the groove 14. At this point, the mounting bracket 2 drives the screw 26 to below the worm gear 16, and the spur gear 15 and rack 23 separate. Then, the electromagnet 265 is energized, making its magnetic poles the same as the magnetic plate 264. Based on the principle of like poles repelling, the magnetic plate 264 is pushed by the repulsive force of the electromagnet 265, causing the teeth 263 to extend out of the slot 262, thus approaching the worm gear 16. The tooth 263 of screw 16 is blocked by the worm 16 and cannot extend. When it is necessary to adjust the distance between the two extrusion plates 21, the drive motor 13 is controlled to rotate, so that the drive motor 13 can drive the worm 16 to rotate, so that the blades of the worm 16 slide along the upper end face of the tooth 263. When the blades of the worm 16 that are blocking the extension of the tooth 263 pass the tooth 263, the tooth 263 will extend out of the slot 262 under the push of the magnetic plate 264, so that the tooth 263 enters between the two blades, so that the worm 16 engages with the screw 26 through the tooth 263. At this time, the rotating worm 16 can drive the screw 26 to rotate through the tooth 263. The movement causes the screw 26 to rotate relative to the sleeve column 261. Since the sleeve column 261 is helically connected to the screw 26 and slidably connected to the mounting bracket 2, the screw 26 rotates relative to the sleeve column 261 and continuously extends out of the sleeve column 261. This causes the sleeve column 261 to continuously move away from the screw 26, allowing the sleeve columns 261 at both ends of the screw 26 to push the extrusion plates 21 away from each other until the extrusion plates 21 reach the desired position. At this point, the electromagnet 265 is de-energized, causing the teeth 263 to enter the strip groove 262 under the drive of the magnetic plate 264. The user first pulls the motor 1 to drive the cutter head 11 to dig a trench in the ground. When the extrusion plate 21 is above the trench, the user controls the spur gear 15 and rack 23 to mesh, allowing the user to drive the mounting frame 2 to descend by driving the spur gear 15. This causes the extrusion plate 21 to descend to the bottom of the trench. At this point, the user continues to dig the trench, enabling the extrusion plate 21 to compact the soil on the inner walls of trenches of different widths and depths. Furthermore, by adjusting the position of the extrusion plate 21, the extrusion force on the inner walls of the trench can be increased, thereby improving the compaction effect on the soil and further enhancing the practicality of the invention.
