Description

Technical Field

[0001] This invention belongs to the field of water conservancy engineering machinery technology, specifically relating to a water bank and ditch trimming machine. Background Technology

[0002] The maintenance of the riverbank and ditch edges is inseparable from excavation. The common construction method is to use existing heavy construction machinery for excavation, and then use manual labor to carry out fine maintenance on the riverbank and ditch edges.

[0003] Firstly, while existing combined heavy machinery construction methods offer advantages such as high efficiency and significant manpower savings, they still suffer from inherent drawbacks in practice, including high skill requirements, difficulties in coordinating different machines, and cumbersome operation. In riverbank and ditch edge repair work, the most commonly used heavy machinery is the excavator. This machine has a wide range of applications and high ditch-digging efficiency; during construction, the main unit only needs to be located on the bank, using a ditch scraper to repair the riverbank and ditch edge.

[0004] However, excavator operation has a high skill ceiling, requiring specialized excavator operators. Operators need extensive training to perform maintenance work, thus significantly increasing labor costs. Furthermore, excavator operators require a high degree of concentration during operation, which is detrimental to their health over extended periods. Additionally, heavy-duty excavators consume a lot of fuel and have low energy efficiency, making them less than ideal machines for riverbank and ditch maintenance.

[0005] Moreover, due to the bulkiness and low precision of heavy machinery, the excavated banks are uneven, requiring manual trimming and correction of the riverbank. Clearly, this method does not meet the requirements of modern development, has low work efficiency, high safety risks, and high labor costs. Summary of the Invention

Detailed Implementation

[0035] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0036] Please refer to the following: Figures 1 to 12 The present invention will now describe the ditch edge trimming machine. The ditch edge trimming machine includes a vehicle body 1, a first output shaft 7 and a second output shaft 8, and further includes a cutting mechanism 2 and a soil compaction mechanism 3.

[0037] like Figures 4 to 7 As shown, the cutting mechanism 2 includes a cutting transmission assembly, a cutting execution assembly that is driven and connected to the cutting transmission assembly, and a cutting angle adjustment assembly 6 for adjusting the cutting angle; the cutting transmission assembly is driven and connected to the first output shaft 7, and the cutting angle adjustment assembly 6 is connected between the cutting transmission assembly and the cutting execution assembly;

[0038] like Figures 8 to 11 As shown, the soil compaction mechanism 3 includes a soil compaction transmission assembly, a soil compaction execution assembly that is driven and connected to the soil compaction transmission assembly, and a soil compaction angle adjustment assembly for adjusting the soil compaction angle; the soil compaction transmission assembly is driven and connected to the second output shaft 8, and the soil compaction angle adjustment assembly 5 is connected between the soil compaction transmission assembly and the soil compaction execution assembly; the soil compaction transmission assembly drives the soil compaction execution assembly to reciprocate and oscillate to compact the soil.

[0039] Compared with the prior art, the waterfront trimming machine provided by this invention has the following advantages: the operator drives the trimming machine to a designated position on the bank, activates the cutting angle adjustment component 6, adjusts the cutting execution component to a suitable angle for cutting the bank, and then drives the cutting execution component to cut and trim the soil on the bank through the cutting transmission component; at the same time as the angle of the cutting execution component is adjusted, the soil compaction angle adjustment component 5 drives the soil compaction execution component to adjust the angle to match the cutting angle; as the soil on the bank is trimmed, the trimming machine moves forward, and the soil compaction transmission component drives the soil compaction execution component to compact the trimmed soil on the bank.

[0040] The waterfront trimming machine provided by this invention can be used to trim and compact the soil on the bank, eliminating or reducing the need for manual trimming and improving work efficiency. At the same time, the cutting angle can be customized to cut the bank shape according to design requirements, which can also improve the effect of the trimmed bank.

[0041] The waterfront trimming machine used in this invention features high efficiency, adjustable trimming depth and angle, wide applicability, and flexible and simple operation. Its process steps are as follows:

[0042] Step 1: Drive the trimming machine to the designated position at the edge of the ditch, according to the required trimming depth and angle;

[0043] Step 2: Shift the forward gear of the trimmer to a low speed.

[0044] Step 3: Lower the cutting execution component to the appropriate angle according to the trimming depth and angle;

[0045] Step 4: Adjust the angle of the compaction actuator to the soil surface;

[0046] Step 5: Activate cutting mechanism 2 and compaction mechanism;

[0047] Step 6: The cutting mechanism 2 cuts the soil surface while the compaction mechanism compacts the soil surface, and the edge of the trench is trimmed.

[0048] Step 7: Retract the cutting mechanism 2 and the compaction mechanism. The trench edge trimming work is now complete.

[0049] This invention relates to a type of engineering machinery. The vehicle body 1 is equipped with a cab, four wheels, an engine, and other drive mechanisms, performing common functions of vehicle-type engineering machinery such as walking, steering, and high / low gear shifting. The vehicle body 1 is the supporting structure of the entire waterfront ditch trimming machine. It needs to support all the components of the whole system, including the engine, clutch, transmission, steering mechanism, drive mechanism, braking mechanism, differential, and other mechanisms. The forces and torques of all mechanisms are ultimately transmitted to the vehicle body 1.

[0050] In some embodiments, such as Figures 4 to 7As shown, the cutting execution assembly includes a cutting drive shaft 216, a cutting main gear 215, a cutting driven gear 214, a cutting main shaft 213, a cutting driven shaft 212, a main sprocket 202, a driven sprocket 205, a chain 203, a cutting housing 201, and a cutting blade 204. The cutting drive shaft 216 is connected to the cutting transmission assembly via a double universal joint 210. The cutting main gear 215 is connected to the cutting drive shaft 216, and the cutting driven gear 214 is connected to the cutting main shaft 213 and meshes with the cutting main gear 215 for cutting. The drive shaft 216, the main cutting gear 215, and the driven cutting gear 214 are all located inside the cutting housing 201; the main cutting shaft 213 and the driven cutting shaft 212 are rotatably connected to the cutting housing 201; the main sprocket 202 is connected to the main cutting shaft 213; the driven sprocket 205 is connected to the driven cutting shaft 212; and the chain 203 meshes with the main sprocket 202 and the driven sprocket 205; several cutting blades 204 are evenly connected to the chain 203; and the cutting angle adjustment assembly 6 is connected between the cutting housing 201 and the cutting transmission assembly.

[0051] This invention employs a chain-type cutting mechanism 2 (203) that operates stably and has a high safety factor, effectively completing the cutting work. It features a main sprocket 202 and a driven sprocket of the same size. When the main sprocket 202 rotates, it drives the chain 203 and the driven sprocket 205 to rotate, thereby rotating the cutting blade 204 to cut the soil and achieve the purpose of shaping the waterfront.

[0052] The cutting process of this invention is as follows: The driver activates the control button, which rotates the first output shaft 7, causing the first transmission shaft 207 and the second transmission shaft 208 of the cutting transmission assembly to rotate, which in turn causes the cutting transmission shaft 216 to rotate. The cutting main gear 215 connected to the cutting transmission shaft 216 rotates, causing the meshing cutting driven gear 214 to rotate. The rotation of the cutting main gear 215 and the cutting driven gear 214 causes the cutting main shaft 213 and the main sprocket 202 to rotate, and then the chain 203 drives the driven sprocket 205 to rotate, thereby realizing the rotational cutting of the cutting blade 204.

[0053] Both the main cutting gear 215 and the driven cutting gear 214 are bevel gears.

[0054] In some embodiments, such as Figures 4 to 7 As shown, both the main sprocket 202 and the driven sprocket 205 are double-row sprockets, and there are two chains 203; each cutting blade 204 is connected to both chains 203 simultaneously. Using double-row sprockets in conjunction with two chains 203, and with the cutting blade 204 connected to both chains 203, can increase the supporting reaction force of the cutting blade 204 during circumferential rotational cutting, thereby increasing the cutting force of the cutting blade 204 and ultimately improving the cutting efficiency and effect.

[0055] In some embodiments, such as Figures 4 to 7As shown, the side of the cutting blade 204 is the cutting edge, and the cutting edge has an angle. For example, the cutting blade 204 is designed with a 15° angle, so that it cuts on one side and the other part does not come into contact with the soil surface, thus reducing the resistance of the cutting equipment from the soil during the cutting process.

[0056] Optionally, the cutting blade 204 has a right-angled trapezoidal structure, with the cutting edge located on the sloping side of the right-angled trapezoid. When cutting into the soil, it gradually cuts into the soil, reducing the soil resistance encountered during cutting.

[0057] In some embodiments, such as Figure 6 As shown, a first bearing 211 is provided on the cutting drive shaft 216. The cutting drive shaft 216 is rotatably connected to the cutting housing 201 through the first bearing 211, which improves the flexibility of the cutting drive shaft 216 rotation. The cutting housing 201 also provides support for the cutting drive shaft 216.

[0058] The cutting drive shaft 216 is connected to the cutting drive assembly via a double universal joint 210. The cutting housing 201 and the cutting drive housing 206 are hinged at the position of the double universal joint 210. The cutting angle adjustment assembly 6 is rotatably connected or hinged to the cutting housing 201. The cutting angle adjustment assembly 6 can drive the cutting mechanism 2 to tilt upward or downward around the double universal joint 210 and the hinge point between the cutting housing 201 and the cutting drive housing 206, cutting and trimming the bank shape with different tilt angles or different slopes.

[0059] Optionally, such as Figures 4 to 7 As shown, the cutting angle adjustment assembly 6 includes a cutting adjustment screw 601, a cutting hinge rod hinged to the cutting adjustment screw 601, and an adjusting nut 603 screwed to the cutting adjustment screw 601. The cutting hinge rod is rotatably connected to the cutting housing 201. A support block 602 is provided on the cutting transmission housing 206. The cutting adjustment screw 601 is threadedly connected to the support block 602. By turning the adjusting nut 603, the cutting adjustment screw 601 can be moved. When the cutting adjustment screw 601 moves in the opposite direction to the cutting blade 204, the entire cutting execution assembly can be lifted upward, thereby increasing the cutting angle. When the cutting adjustment screw 601 extends towards the cutting blade 204, it pushes the cutting execution assembly downward, reducing the cutting angle.

[0060] By connecting the cutting actuator and the cutting transmission assembly via a double universal joint 210, the tilt angle of the cutting actuator can be adjusted from 0 to 90 degrees, enabling 0-90° cutting of the riverbank. After cutting the soil surface, the loose soil is compacted by the soil compaction mechanism 3, making the trimmed riverbank and ditch edge more stable and smooth.

[0061] The soil compaction angle adjustment component 5 in the soil compaction mechanism 3 has the same structure and the same angle adjustment method as the cutting angle adjustment component 6, and can also achieve compaction of soil surface from 0-90°.

[0062] Adding a compaction mechanism not only ensures that the trimmed ditch edge has a high trimming accuracy, but also reduces the impact of the soil cut off by the cutting mechanism 2 on the smoothness of the trimmed ditch edge. Therefore, a compaction mechanism can be set behind the cutting mechanism 2.

[0063] Optionally, the cutting angle adjustment assembly 6 includes linear actuators such as cylinders, hydraulic cylinders, or electric push rods rotatably connected to the cutting transmission housing 206. The actuator rods of each linear actuator are hinged to the cutting housing 201. By extending or retracting the actuator rods, the tilt angle of the cutting mechanism 2 is adjusted, thereby achieving the angle adjustment of the cutting surface. The soil compaction angle adjustment assembly 5 has the same structure as the cutting angle adjustment assembly 6.

[0064] In some embodiments, such as Figures 4 to 7 As shown, the cutting transmission assembly includes a first transmission shaft 207 and a second transmission shaft 208 connected by a universal joint. The first transmission shaft 207 is connected to the first output shaft 7 via a coupling or spline sleeve. A cutting transmission housing 206 is provided on the outside of the second transmission shaft 208. A second bearing 209 is provided on the second transmission shaft 208 and rotatably connected to the cutting transmission housing 206 to enable the second transmission shaft 208 to rotate flexibly and to provide support for the second transmission shaft 208. A cutting transmission shaft 216 is connected to the second transmission shaft 208 via a double universal joint 210. A cutting angle adjustment assembly is connected to the cutting housing 201 and the cutting transmission housing 206. The cutting housing 201 and the cutting transmission housing 206 are connected (rotatably connected via a rotating shaft).

[0065] The first drive shaft 207 and the second drive shaft 208 are connected by a universal joint. The cutting transmission housing 206 is rotatably connected to the vehicle body 1, and the connection point is at the same position as the universal joint, so that the support assembly 4 below can lift the entire cutting mechanism 2 and adjust the angle between the entire cutting mechanism 2 and the inclined surface of the bank. The cutting housing 201 is rotatably connected to the cutting transmission housing 206, so that the cutting angle adjustment assembly 6 can adjust the overall tilt angle of the cutting execution assembly.

[0066] It should be noted that the plane formed by the cutting blades 204 has the same tilt angle as the pre-set shoreline, that is, the same slope that the shoreline needs to be trimmed; the soil pressing plate 301 also has the same tilt angle as the shoreline slope.

[0067] In some embodiments, such as Figures 8 to 11As shown, the soil compaction actuator includes a soil compaction drive shaft 311, a soil compaction main gear 312, a soil compaction driven gear 313, a soil compaction main eccentric shaft 302, a soil compaction driven eccentric shaft 303, a connecting rod 304, a soil compaction housing 305, and a soil compaction plate 301. The soil compaction drive shaft 311 is connected to the soil compaction drive assembly via a double universal joint 210. The soil compaction main gear 312 is connected to the soil compaction drive shaft 311, and the soil compaction driven gear 313 is connected to the soil compaction main eccentric shaft 302 and... The soil main gear 312 is engaged, and the soil compaction drive shaft 311, the soil compaction main gear 312, and the soil compaction driven gear 313 are all located inside the soil compaction housing 305; the soil compaction main eccentric shaft 302 and the soil compaction driven eccentric shaft 303 are rotatably connected to the soil compaction housing 305; the connecting rod 304 is connected to the soil compaction main eccentric shaft 302 and the soil compaction driven eccentric shaft 303, and the soil compaction plate 301 is connected to the connecting rod 304; the soil compaction angle adjustment assembly is connected between the soil compaction housing 305 and the soil compaction drive assembly.

[0068] The soil compaction process of this invention is as follows: The driver activates the control button, which rotates the second output shaft 8, driving the third transmission shaft 307 and the fourth transmission shaft 309 of the soil compaction transmission assembly to rotate, which in turn drives the soil compaction transmission shaft 311 to rotate. The soil compaction main gear 312 connected to the soil compaction transmission shaft 311 rotates, driving the meshing soil compaction driven gear 313 to rotate. The rotation of the soil compaction main gear 312 and the soil compaction driven gear 313 drives the soil compaction main eccentric shaft 302 to rotate. The second output shaft 8 rotates in both directions, causing the connecting rod 304 to swing, which in turn drives the compaction plate to swing back and forth, compacting the soil. The connecting rod 304 is connected to the middle position of the soil compaction plate 301. When one end of the soil compaction plate 301 is raised, the other end is pressed down, compacting the soil.

[0069] By using the eccentric shaft, the eccentric angle of the connecting rod 304 can be increased, thereby increasing the swing amplitude of the soil compaction plate 301, increasing the compaction force, and thus improving the soil compaction effect.

[0070] Among them, the soil pressing main gear 312 and the soil pressing driven gear 313 are both bevel gears.

[0071] In some embodiments, such as Figures 8 to 11 As shown, the earth compaction transmission assembly includes a third transmission shaft 307 and a fourth transmission shaft 309 connected by a universal joint. The third transmission shaft 307 is connected to the second output shaft 8 via a coupling or spline sleeve. An earth compaction transmission housing 306 is provided on the outside of the fourth transmission shaft 309. A fourth bearing 310 is provided on the fourth transmission shaft 309 and is rotatably connected to the earth compaction transmission housing 306 to enable the fourth transmission shaft 309 to rotate flexibly and to provide support for the fourth transmission shaft 309. The earth compaction transmission shaft 311 is connected to the fourth transmission shaft via a double universal joint 210. The earth compaction angle adjustment assembly is connected to the earth compaction housing 305 and the earth compaction transmission housing 306.

[0072] In some embodiments, such as Figure 11 As shown, a third bearing 308 is provided on the soil compaction drive shaft 311. The soil compaction drive shaft 311 is rotatably connected to the soil compaction housing 305 through the third bearing 308, which improves the flexibility of the rotation of the soil compaction drive shaft 311. The soil compaction housing 305 also provides support for the soil compaction drive shaft 311.

[0073] In some embodiments, such as Figures 1 to 6 , Figures 8 to 10 As shown, a support assembly 4 is provided below both the cutting transmission assembly and the soil compaction transmission assembly, and the lower end of the support assembly 4 is connected to the vehicle body 1. The support assembly 4 provides support for both the cutting mechanism 2 and the soil compaction mechanism 3.

[0074] Optionally, such as Figures 1 to 6 , Figures 8 to 10 As shown, the support assembly 4 includes a support screw 401 and a support nut 402. The support screw 401 is threadedly connected to the support plate on the vehicle body 1, and the support nut 402 is screwed onto the support screw 401. The support screw 401 is hinged to the cutting transmission housing 206. Rotating the support nut 402 can drive the support screw 401 to rise or fall, thereby adjusting the overall tilt angle of the cutting mechanism 2; the support assembly 4 below the compaction mechanism works on the same principle.

[0075] Optionally, the support assembly 4 includes linear actuators such as cylinders, hydraulic cylinders or electric push rods that are hinged to the support plate on the vehicle body 1. The actuator rods of each linear actuator are hinged to the cutting transmission housing 206 and the soil compaction transmission housing 306, respectively. By extending or retracting the actuator rods, the tilt angles of the cutting mechanism 2 and the soil compaction mechanism 3 are adjusted, thereby realizing the angle adjustment of the cutting surface and the soil compaction surface.
