Description

Technical Field

[0001] This invention belongs to the field of loosening soil in green belts, and specifically relates to a soil loosening device for road green belts. Background Technology

[0002] Currently, greenbelt loosening equipment is typically mounted on engineering vehicles. These vehicles move the equipment along the greenbelt, and when avoiding streetlights within the greenbelt, the vehicles must slow down or stop to ensure the equipment is removed first. This obstructs traffic flow, preventing vehicles from passing normally and causing congestion. Furthermore, it prevents proper loosening of the soil near streetlights, creating dead zones. Existing loosening equipment usually requires cleaning the blades after work, but during operation, soil adheres tightly to the blades, reducing their loosening effectiveness. In some cases, the blades and soil can even combine to form a roller-like shape, completely eliminating their loosening effect. To mitigate this problem, existing blades often have large gaps between the blades, resulting in loosening dead zones and requiring multiple passes, wasting considerable time. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following advantages: When in use, the present invention enables the power system, fixed cylinder, fixed ring and loosening blade to rotate by starting the drive motor, thereby adapting to the curved part of the green belt; by controlling the extension and retraction of the second electric push rod, the depth of the loosening blade inserted into the soil can be adjusted to meet different loosening depth requirements; and by controlling the activation of the warning light, the road vehicles are alerted.

[0015] When the obstacle detector detects a streetlight in the green belt, the mechanical clamp clamps the streetlight pole, the second electric push rod retracts, and then the electric shaft on the first fixed plate rotates the second fixed plate, causing the second electric push rod to rotate the connecting plate away from the curb, so that the electric wheel and the caster are both above the curb. Then the electric roller in the mechanical clamp starts, causing the entire device to rotate 360 ​​degrees and then 180 degrees around the streetlight pole as the axis. This allows the loosening blade to pass around the streetlight pole, loosening the soil around the pole and avoiding any dead spots. At the same time, without leaving the green belt, the device bypasses the streetlight pole to avoid blocking the lane and affecting traffic. This cycle repeats, achieving automatic obstacle avoidance and unmanned soil loosening.

[0016] The soil-breaking blade is offset away from the loosening blade, thereby increasing the loosening range of the soil and avoiding dead spots in the loosening process. At the same time, the double-blade design of the soil-breaking blade makes the soil break up more finely, enhancing the loosening effect. The blade further divides the soil at the location where the loosening blade breaks it up, while the second fixing rod drives the blade to rotate, thereby further enhancing the loosening effect of the blade.

[0017] After the soil-breaking blade detaches from the soil, the torsion spring shaft releases its elastic force to reset the soil-breaking blade. The instantaneous reset of the soil-breaking blade impacts the reset spring, which in turn causes the soil-breaking blade to vibrate, shaking off the soil adhering to the soil-breaking blade and preventing the soil from sticking to the soil-breaking blade and affecting the soil-loosening effect.

[0018] The cleaning plate is inserted into the gap between the two blades of the soil-breaking blade, which opens the two blades to allow the soil stuck between them to fall off. At the same time, the cleaning plate scrapes off the soil adhering to the two blades. Then, the loosening blade rotates between two third fixed plates, and the lever pushes off the soil adhering to the loosening blade. Multiple scrapers scrape off the soil adhering to the loosening blade. Then, the blade passes through the gap between two corresponding scrapers, and the soil adhering to the blade is scraped off, thus ensuring the loosening effect of the loosening blade and the blade.

[0019] Control the electric slider to slide towards the center of the electric slide rail, which in turn causes the mounting sleeve to slide towards the center of the fixed cylinder. This prevents the loosening and breaking systems on the outermost mounting sleeve from colliding with the curb when the device rotates around the street light pole. At the same time, the above operation can be used to fine-tune the loosening range to adapt to the width of the green belt. Attached Figure Description

Detailed Implementation

[0033] 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.

[0034] Example 1

[0035] A soil loosening device for roadside green belts, such as Figure 1-6 As shown, it includes a mounting plate 1, a drive motor 2, a first fixing rod 3, an obstacle detector 4, and a protective plate 5; the drive motor 2 is bolted to the upper side of the mounting plate 1; the output shaft of the drive motor 2 is fixed to the first fixing rod 3; the protective plate 5 is bolted to the middle of the first fixing rod 3; an obstacle detector 4 is installed on the upper front and upper rear of the mounting plate 1, and the drive motor 2 is located between the two obstacle detectors 4, which detect the streetlights in the green belt through the obstacle detectors 4;

[0036] It also includes a fixed cylinder 103, a soil loosening system and a power system; the power system is connected to the lower side of the first fixed rod 3; a fixed cylinder 103 is connected to the left and right sides of the power system; three equidistant soil loosening systems are fixed to each of the two fixed cylinders 103.

[0037] The soil loosening system includes a fixing ring 108 and soil loosening blades 109; the fixing ring 108 is fixedly connected to the fixing cylinder 103; fourteen soil loosening blades 109 are circumferentially fixed to the fixing ring 108. The soil loosening blades 109 are made of alloy steel and the blades of the soil loosening blades 109 are plow-shaped. The power system drives the fixing cylinder 103, the fixing ring 108 and the soil loosening blades 109 to rotate, and the soil loosening blades 109 loosen the soil 003 in the green belt.

[0038] The power system includes a mounting cylinder 101 and a dual-axis motor 102; the mounting cylinder 101 is welded to the lower side of the first fixing rod 3; the dual-axis motor 102 is bolted inside the mounting cylinder 101; the mounting cylinder 101 is rotatably connected to two fixing cylinders 103; the two output shafts of the dual-axis motor 102 are each fixedly connected to one fixing cylinder 103.

[0039] In use, the mounting plate 1 is installed on the external moving device, allowing the loosening blade 109 to insert into the soil 003 of the green belt. Then, the dual-axis motor 102 is started, and its output shaft drives the fixed cylinder 103, fixed ring 108, and loosening blade 109 to rotate. Simultaneously, the external moving device moves the mounting plate 1 along the direction of the green belt. As the loosening blade 109 rotates, its plow-shaped head inserts into the soil 003 of the green belt, breaking and dispersing the soil 003 at the plow-shaped head. Thus, the rotation of the loosening blade 109 continuously loosens the soil in the green belt. The soil 003 in the green belt is loosened by controlling the start of the drive motor 2. The output shaft of the drive motor 2 drives the power system, the fixed cylinder 103, the fixed ring 108 and the loosening blade 109 to rotate. The external moving device coordinates with the steering to adapt to the curved part of the green belt. At the same time, the obstacle detector 4 detects the street lights in the green belt. When the street lights in the green belt are detected, the external moving device drives the mounting plate 1, the fixed cylinder 103, the fixed ring 108 and the loosening blade 109 to withdraw from the green belt in advance to avoid the loosening blade 109 from colliding with the street lights.

[0040] Example 2

[0041] Based on Example 1, such as Figure 1-2 As shown,

[0042] It also includes a walking system; the walking system includes a first electric push rod 201, a first fixed plate 202, a second fixed plate 203, a second electric push rod 204, a connecting plate 205, a first elastic element 206, a first mounting bracket 207, an electric wheel 208, and a caster wheel 209; a first electric push rod 201 is bolted to the middle of the left side and the middle of the right side of the mounting plate 1; a first fixed plate 202 is fixed to the telescopic end of each of the two first electric push rods 201; a second fixed plate 203 is connected to the opposite sides of the two first fixed plates 202 through an electric rotating shaft, and the second fixed plate 203 is rotated by the electric rotating shaft. The device is movable; each of the two second fixed plates 203 is bolted to a second electric push rod 204; each of the two second electric push rods 204 is fixed to a connecting plate 205 at its telescopic end; each of the two connecting plates 205 is fixed to two first elastic elements 206 on their opposing sides; each of the telescopic ends of the first elastic elements 206 is fixed to a first mounting bracket 207; each of the first mounting brackets 207 is equipped with an electric wheel 208, and a pressure sensor is installed inside the electric wheel 208; each of the first mounting brackets 207 is bolted to a universal wheel 209, which provides support to the device by contacting the road surface 001.

[0043] It also includes mechanical clamps 401; one mechanical clamp 401 is fixed to the front and one to the rear of the mounting plate 1; and several electric rollers 006 are provided inside each of the two mechanical clamps 401.

[0044] Existing greenbelt loosening equipment is typically mounted on engineering vehicles. The vehicle moves the equipment along the greenbelt, and when avoiding streetlights within the greenbelt, the vehicle must slow down or stop to ensure the equipment is removed first. This obstructs traffic flow, preventing vehicles from passing normally and potentially causing congestion. The device is supported by the universal wheels 209 contacting the road surface 001. Then, the first electric push rod 201 retracts, causing the first fixing plate 202 to drive the second fixing plate 203, the second electric push rod 204, and the connecting plate 2... 05. The first elastic element 206, the first mounting bracket 207, the electric wheel 208, and the swivel wheel 209 move towards the curb 002, causing the electric wheel 208 to contact and be compressed against the curb 002. This compresses the first elastic element 206, and then controls the electric wheel 208 to start, providing the power for the device to move and guide it. When passing through the curved section of the green belt, the pressure sensor value inside the electric wheel 208 changes, which in turn starts the drive motor 2, causing the power system, the fixed cylinder 103, the fixed ring 108, and the loosening blade 109 to rotate, thereby adapting to... For the curved sections of the green belt, the extension and retraction of the second electric push rod 204 is controlled to adjust the depth of the loosening blade 109 inserted into the soil 003, meeting different loosening depth requirements. The warning light 005 is activated to alert road vehicles. When the obstacle detector 4 detects a streetlight within the green belt, the mechanical clamp 401 clamps the streetlight pole 004, the second electric push rod 204 retracts, and then the electric shaft on the first fixing plate 202 drives the second fixing plate 203 to rotate, causing the second electric push rod 204 to move the connecting plate 205 away from the curb 002. The device rotates so that both the electric wheel 208 and the omnidirectional wheel 209 are above the curb 002. Then, the electric roller 006 inside the mechanical clamp 401 is activated, causing the entire device to rotate 360 ​​degrees and then 180 degrees around the lamp post 004 as an axis. This allows the loosening blade 109 to pass around the lamp post 004, loosening the soil 003 around the lamp post 004 and avoiding any dead spots in the loosening process. At the same time, without leaving the green belt, the device bypasses the lamp post 004 to avoid occupying the lane and affecting traffic. This cycle repeats continuously, achieving automatic obstacle avoidance and unmanned loosening of soil.

[0045] Example 3

[0046] Based on Example 2, such as Figure 4-8 As shown,

[0047] It also includes a soil-breaking system; including soil-breaking blades 110, return springs 111, and soil-breaking units; each fixed ring 108 has fourteen soil-breaking blades 110 connected to its left and right sides via torsion spring shafts. The soil-breaking blades 110 are made of alloy steel, with curved blade heads. Each soil-breaking blade 110 is a double-blade design with a certain degree of elasticity between the two blades. The soil-breaking blades 110 on the left and right sides of each fixed ring 108 are staggered, through... The soil-breaking blade 110 is inserted into the soil 003 on both sides of the loosening blade 109, thereby loosening the soil 003 on both sides of the loosening blade 109; a return spring 111 is fixedly connected to the side of each soil-breaking blade 110 facing the loosening blade 109; all return springs 111 are fixedly connected to the fixing ring 108; a soil-breaking unit is connected to each soil-breaking blade 110 on the left side; each soil-breaking unit is connected to a loosening blade 109; each soil-breaking unit is connected to the fixing ring 108.

[0048] The soil-breaking unit includes a guide wheel 112, a pull rope 113, a second fixing rod 115, a first torsion spring 116, a blade 117, a bending frame 210, and an arc-shaped block 211. A pull rope 113 is fixedly connected to the side of the soil-breaking blade 110 facing the loosening blade 109. The guide wheel 112 is rotatably connected inside the fixing ring 108. The second fixing rod 115 is rotatably connected to the loosening blade 109. The pull rope 113 passes through a return spring 111 and then wraps around the guide wheel 112, with the end of the pull rope 113 wound around the second fixing rod 211. On rod 115; a first torsion spring 116 is fixedly connected to the second fixed rod 115; the first torsion spring 116 is fixedly connected to the loosening blade 109; three blades 117 are fixedly connected to the second fixed rod 115; a number of bending frames 210 corresponding to the number of fixing rings 108 are detachably connected to the lower front part of the protective plate 5; two left-right symmetrical arc blocks 211 are fixedly connected to the lower part of each bending frame 210, and the soil breaking blade 110 is squeezed by the arc blocks 211, causing the soil breaking blade 110 to shift away from the loosening blade 109.

[0049] It also includes a protective cloth 114, which is an elastic cloth; each soil-breaking blade 110 is fixedly connected to a protective cloth 114 on the side facing the loosening blade 109, and all protective cloths 114 are fixedly connected to the fixing ring 108. The protective cloth 114 protects the connection position between the soil-breaking blade 110 and the fixing ring 108, preventing soil from falling in and affecting the normal operation of the soil-breaking blade 110.

[0050] The fixed ring 108 drives the loosening blade 109 to rotate, simultaneously driving the breaking blade 110 to rotate. The loosening blade 109, upon inserting into the soil 003, contacts and is compressed by the arc-shaped block 211, causing it to rotate about the torsion spring shaft at its connection with the fixed ring 108. This torsion spring shaft twists, causing the breaking blade 110 to shift away from the loosening blade 109, thus increasing the loosening range of the soil 003. Simultaneously, the double-blade design of the breaking blade 110 allows it to break the soil 003 into finer pieces, enhancing the loosening effect. As the breaking blade 110 shifts away from the loosening blade 109, it pulls the rope 113, causing... The pull rope 113 drives the second fixed rod 115 to rotate inside the loosening blade 109, causing the first torsion spring 116 to twist. At the same time, the blade 117 further divides the soil 003 by breaking through the soil 003 position. Simultaneously, the second fixed rod 115 drives the blade 117 to rotate, thereby further enhancing the soil loosening effect of the blade 117. When the breaking blade 110 is separated from the soil 003, the torsion spring shaft releases its elastic force to reset the breaking blade 110. The breaking blade 110 resets instantly and hits the reset spring 111, thereby causing the breaking blade 110 to vibrate and shake off the soil adhering to the breaking blade 110, preventing the soil from sticking to the breaking blade 110 and affecting the soil loosening effect.

[0051] Example 4

[0052] Based on Example 3, such as Figure 9-12 As shown,

[0053] It also includes a cleaning system; the cleaning system includes a third fixed rod 301, a sliding rod 302, a second fixed frame 303, a cleaning plate 304, a second mounting frame 305, a third fixed plate 308, a scraping unit, and a mud-removing unit; the third fixed rod 301 is welded to the lower front part of the protective plate 5 via a connecting block; two mutually symmetrical sliding rods 302 are slidably connected inside the third fixed rod 301; several second fixed frames 303 are bolted to the third fixed rod 301 and the sliding rods 302, each second fixed frame 303 corresponding to a fixed ring 108; two mutually symmetrical cleaning plates 304 are bolted to the lower part of each second fixed frame 303; a second mounting frame 305 is bolted to the middle of each second fixed frame 303; two mutually symmetrical third fixed plates 308 are welded to each second mounting frame 305; three scraping units are circumferentially connected inside each second mounting frame 305; and two mud-removing units are connected to each third fixed plate 308.

[0054] The scraping unit includes a second elastic element 306 and a scraper 307; two second elastic elements 306 are welded inside the second mounting bracket 305 through a connecting block; each of the two second elastic elements 306 has a scraper 307 fixedly connected to its telescopic end, and the scraper 307 is configured as an L-shape.

[0055] The mud-removing unit includes a fourth fixed rod 309, a second torsion spring 310, and a lever 311; the fourth fixed rod 309 is rotatably connected inside the third fixed plate 308; five equally spaced levers 311 are fixedly connected to the fourth fixed rod 309; all levers 311 are rotatably connected to the third fixed plate 308; the second torsion spring 310 is sleeved on the lever 311, and the second torsion spring 310 is fixedly connected to the third fixed plate 308.

[0056] After the soil-breaking blade 110 detaches from the soil 003, it rotates and passes through the cleaning plate 304. The cleaning plate 304 engages with the gap between the two blades of the soil-breaking blade 110, spreading the two blades apart to allow the soil stuck between them to fall off. Simultaneously, the cleaning plate 304 scrapes away the soil adhering to the two blades. Next, the loosening blade 109 rotates between the two third fixing plates 308. The lever 311 removes the soil adhering to the loosening blade 109, causing the lever 311 to rotate the fourth fixing rod 309, thus twisting the second torsion spring 310. As the loosening blade 109 passes between the two... After the third fixing plate 308 is installed, the second torsion spring 310 releases its elastic force, causing the fourth fixing rod 309 to drive the lever 311 to reset instantly, thereby knocking off the soil adhering to the lever 311, ensuring the cleaning effect of the lever 311 on the loosening knife 109. At the same time, the blade of the loosening knife 109 passes through the gap between multiple scrapers 307, and the soil adhering to the loosening knife 109 is scraped off by the multiple scrapers 307. Then, the blade 117 passes through the gap between two corresponding scrapers 307, and the soil adhering to the blade 117 is scraped off, thereby ensuring the loosening effect of the loosening knife 109 and the blade 117.

[0059] It also includes mounting sleeves 104, electric slide rails 105, electric sliders 106, and first fixing frames 107; an electric slide rail 105 is fixedly connected to the lower rear part of the protective plate 5; two electric sliders 106 are slidably connected to the electric slide rails 105; a first fixing frame 107 is bolted to the upper and lower sides of each of the two electric sliders 106; each of the two first fixing frames 107 is bolted to a slide rod 302; a mounting sleeve 104 is fixedly connected inside each of the two first fixing frames 107; each of the two mounting sleeves 104 is inserted into a fixing cylinder 103; another mounting sleeve 104 is bolted to the opposite sides of each of the two mounting sleeves 104, and bolt holes for fixing the additional mounting sleeve 104 are provided on the mounting sleeves 104; the four mounting sleeves 104 are also provided with a soil loosening system and a soil breaking system.

[0060] By inserting an installation sleeve 104 into the fixed cylinder 103 and by bolting an additional installation sleeve 104 onto the installation sleeve 104, the device can adapt to green belts of different widths. At the same time, the sliding rod 302 is pulled out of the third fixed rod 301 by a predetermined length, and a number of cleaning systems corresponding to the installation sleeve 104 are installed on the sliding rod 302. Then, the sliding rod 302 is fixed in the first fixed frame 107 with bolts. When the device rotates around the street light pole 004, the electric slider 106 is controlled to slide towards the middle of the electric slide rail 105, thereby causing the installation sleeve 104 to slide towards the middle of the fixed cylinder 103. This prevents the soil loosening system and soil breaking system on the outermost installation sleeve 104 from colliding with the curb 002 when the device rotates around the street light pole 004. At the same time, the above operations can achieve the effect of fine-tuning the soil loosening range to adapt to the width of the green belt.

[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
