Description

Technical Field

[0001] The present invention relates to the technical field of protective net covering, in particular to a protective net covering device for green ecological slope construction. Background Art

[0002] The protective net covering device for slope construction is designed to improve slope stability and promote vegetation recovery. The device is usually composed of a protective net made of metal or synthetic fiber materials. The mesh structure has good tensile strength and can effectively resist the impact of natural disasters such as slope landslides and soil erosion. After the protective net is laid, it is reasonably tensioned and fixed to form close contact with the ground, ensuring that the mesh can firmly cover the slope surface, prevent soil erosion, and provide a suitable habitat for plant growth on its surface.

[0003] In the existing technology, the laying of protective nets mainly focuses on slope stability and soil protection, but the combination of sowing and protective nets is rarely optimized. Traditional technology often involves laying protective nets separately and then sowing separately. It is difficult to achieve an effective combination of sowing and protective nets, resulting in the growth of seeds being restricted by the coverage of the protective nets, resulting in poor growth effects.

[0004] Chinese Patent Publication No. CN217651819U discloses a slope protection net laying device, comprising a support base, a support plate, a first bracket, and a pull rod. The device comprises two support bases, each of which has a support plate clamped to its upper portion. The first bracket and pull rod are mounted on the front support plate. The patent document discloses the following beneficial effects: upon starting the motor, the protection net unwinds from the first connecting rod and is laid flat on the slope from left to right, achieving an automatic laying effect for the slope protection net. The operation is simple and convenient, and the net is laid neatly, saving manpower to a certain extent and providing convenience for people.

[0005] Although the above patent document can play a role in laying protective nets during use, it cannot lay nets on slopes during the actual laying process. In addition, when the slope laying work is completed, other external devices are required to sow seeds on the slope, which wastes a lot of laying time. Summary of the Invention

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] Example 1, as Figure 1 and Figure 2As shown, a green ecological slope construction protection net laying device comprises two symmetrically distributed L-shaped outer frames 1, wherein the lower middle part of the rear end of the two L-shaped outer frames 1 is provided with a track 2 extending to the front end thereof, and the upper ends of the two L-shaped outer frames 1 are fixedly mounted with a switching assembly 3. By means of the provided switching assembly 3, when laying the protection net on the slope surface, the raised soil blocks on the slope surface can be crushed during the process of laying the net, so as to avoid the situation in which the raised soil blocks pull the protection net out of shape or break during the subsequent laying of the net, and the provided net laying assembly 4 cooperates with the switching assembly 3 during use to switch between the two modes of laying the net and sowing seeds, thereby improving the versatility of the device.

[0034] The outer surfaces of the two switching components 3 are jointly fixedly mounted with a net-releasing component 4. Through the setting of the net-releasing component 4, during use, after the protective net is laid, the switching component 3 can be driven to switch to the sowing structure, and then return to the initial net-laying position to sow seeds on the slope surface. No subsequent manual or other mechanical devices are required for sowing operations, thereby improving the overall efficiency of slope construction.

[0035] During the use of this solution, the entire device needs to be used in conjunction with the lining machine in the existing technology. At the same time, the tracks 2 opened in the middle of the rear end of the two L-shaped outer frames 1 need to be installed and engaged with the slide rail surface respectively. Before the slope is constructed, the slide rail has been pre-laid on the upper and lower sides of the slope, and the slide rail elevations on the upper and lower platforms on the slope must meet the drawing requirements of the slope lining machine to ensure that the vertical distance between the lining surface of the lining machine and the slope is consistent, thereby ensuring that the later slope finishing and lining quality are guaranteed during the process of laying the protective net using this device.

[0036] Therefore, the slide rails and lining machines mentioned above are conventional settings in the prior art, and their specific installation methods and control methods are conventional designs, so this solution will not elaborate on them in detail.

[0037] Example 2: Based on Example 1, this example aims to crush the raised soil blocks on the slope surface during the laying of the protective net, and at the same time switch the device after the protective net is laid to achieve the purpose of sowing.

[0038] For details, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10The switching components 3 include two fixed columns 31 fixedly connected at the rear ends of the upper ends of the horizontal directions of the two L-shaped outer frames 1, and the outer surfaces of the two fixed columns 31 are fixedly connected to hydraulic cylinders 32. The ends of the vertical parts of the two L-shaped outer frames 1 that are away from each other are movably connected to drive plates 33. The lower parts of the ends of the two drive plates 33 that are away from each other are provided with two symmetrically distributed arc grooves 34. The ends of the vertical parts of the two L-shaped outer frames 1 that are away from each other are rotatably connected to two limit columns 35.

[0040] Furthermore, an extension rod 370 is rotatably connected to the right side wall of the inner surface of the left opening plate 376, and a motor 3701 is fixedly connected to the left side wall of the inner surface of the right opening plate 376. The right end of the extension rod 370 is fixedly connected to the main roller 3702, and the right end of the main roller 3702 is fixedly connected to the output end of the motor 3701 through a coupling. The left and right sides of the outer surface of the main roller 3702 are rotatably connected to the limiting hollow blocks 3703, and the upper and lower ends of the two limiting hollow blocks 3703 are respectively fixedly connected to the bottom wall and bottom wall of the inner surface of the opening plate 376 on the same side, and a number of crushing plates 3704 are fixedly connected to the annular array in the middle of the outer surface of the main roller 3702.

[0041] Furthermore, the net-releasing assembly 4 includes a fixing plate 41 fixedly connected to the upper ends of the two driving plates 33, and the upper ends of the two fixing plates 41 are commonly fixedly connected to a bottom arc box 42. The upper end of the bottom arc box 42 is provided with two mounting grooves 43, and a blanking port 44 is provided on the side where the inner arc surfaces of the two mounting grooves 43 are close to each other. A placing roller assembly 46 is commonly fixedly installed in the middle of the left side wall and the middle of the right side wall of the inner surface of the rear side mounting groove 43.

[0042] Furthermore, the roller assembly 46 includes two receiving arc plates 461, and the ends of the two receiving arc plates 461 that are away from each other are respectively fixedly connected to the middle of the left wall and the middle of the right wall of the inner surface of the rear side mounting groove 43. The inner arc surfaces of the two receiving arc plates 461 are each provided with a driving rod 462, and the ends of the two driving rods 462 that are away from each other are each provided with a pentagonal groove 1 463. The ends of the two driving rods 462 that are close to each other are jointly fixedly connected with a mounting roller 464. Pentagonal rods 465 are inserted into the inner surfaces of the two pentagonal grooves 1 463. The ends of the two pentagonal rods 465 that are away from each other are each fixedly connected with a round block 466. The ends of the two round blocks 466 that are away from each other are each provided with a pentagonal groove 2 467. A sliding assembly 468 is slidably installed on the outer arc surface of the lower side of the bottom arc box 42.

[0043] Furthermore, the sliding assembly 468 includes an arc-shaped outer plate 4681 that is slidably connected to the outer arc surface of the lower side of the bottom arc box 42. A blanking opening 4682 is provided on the front side and the rear side of the outer surface of the arc-shaped outer plate 4681. An arc-shaped tooth plate 4683 is fixedly connected to the middle of the left side and the middle of the right side of the outer surface of the arc-shaped outer plate 4681.

[0044] Furthermore, a driving mechanism is fixedly installed at the left end of the left gear 371, the two gears 371 are respectively engaged with the arc-shaped toothed plate 4683 on the same side, and the upper ends of the two connecting blocks 36 are respectively fixedly connected to the lower ends of the fixed plate 41 on the same side.

[0045] First, you need to pull out the two pentagonal rods 465 from the pentagonal slots 463 on both sides to remove the limit on the driving rod 462. Then, lift the installation roller 464, put the protective net roller to be laid on the outer surface of the installation roller 464, and then place the driving rods 462 at both ends of the installation roller 464 in the corresponding receiving arc plates 461.

[0046] At this time, the two pentagonal rods 465 can be inserted into the corresponding pentagonal grooves 463 again. In this solution, the two pentagonal rods 465 can be smoothly inserted into the two pentagonal grooves 463 by respectively opening holes at the left and right ends of the bottom arc box 42 corresponding to the positions of the pentagonal grooves 463 on the same side.

[0047] When the protective net needs to be laid, a wrench that matches the shape of the pentagonal slots 467 on both sides can be inserted into it, and then rotated to cause the pentagonal rod 465 to drive the driving rod 462 to rotate, and then the two driving rods 462 drive the installation roller 464 to rotate, thereby releasing the protective net roller installed on the surface of the installation roller 464;

[0048] Then, by activating the hydraulic cylinders 32 on both sides, the output ends of the hydraulic cylinders 32 on both sides drive the connecting blocks 36 fixed thereto to retract inwards at the same time. During the retraction process, since the connecting block 36 on the same side is fixedly connected to the lower front end of the fixing plate 41 on the same side, and the two arc grooves 34 on the surface of the driving plate 33 on the same side are limited by the limiting columns 35 fixedly connected to the surface of the L-shaped outer frame 1 on the same side, when the connecting block 36 retracts inwards with the hydraulic cylinder 32, it can simultaneously drive the driving plate 33 to move inwards in an arc shape. When the fixing plate 41 moves in the moving direction of the connecting block 36, the two fixing plates 41 can simultaneously drive the bottom arc box 42 fixed thereto to deflect in the same direction.

[0049] At the same time, the driving mechanism fixedly installed at the left end of the left gear 371 is started, so that the driving mechanism drives the gear 371 to rotate, and the driving mechanism drives the gear 371 to rotate in the opposite direction of the movement direction of the connecting block 36, and the rotation frequency of the gear 371 is equal to the expansion and contraction frequency of the hydraulic cylinder 32. Therefore, when the gear 371 rotates, it can simultaneously drive the arc-shaped toothed plate 4683 meshing therewith to move, and the arc-shaped toothed plate 4683 is fixedly connected to the outer arc surface of the arc outer plate 4681, and the inner arc surface of the arc outer plate 4681 is slidably connected to the outer arc surface of the lower side of the bottom arc box 42. Therefore, when the arc outer plate 4681 moves, the blanking port 2 4682 on the rear side of its outer surface and the blanking port 1 44 on the rear side of the inner arc surface of the bottom arc box 42 can be aligned with each other;

[0050] At this time, the released protective net can be pulled out from the blanking port 1 44 and the blanking port 2 4682, and the pulled-out section of the protective net can be fixed on one side of the slope. Then, when it is necessary to lay the protective net, it is only necessary to move the bottom arc box 42 along with the lining machine to the position where the protective net is not laid. During the movement, the protective net roller installed on the outer surface of the installation roller 464 will continuously release the protective net on its surface.

[0051] During the process of laying the protective net, the motor 3701 can be started at the same time. Before that, since the winding roller 372 rotates along with the gear 371, the winding roller 372 can release the connecting rope 379 wrapped around its surface, so that the connecting rope 379 no longer pulls the hanging ring 378, and then the opening plates 376 on both sides slide downward in the guide groove 375 on the same side.

[0052] After the motor 3701 is started, its output end drives the main roller 3702 to rotate through the coupling. When the main roller 3702 rotates, it can simultaneously drive a number of crushing plates 3704 fixedly connected to its outer surface to rotate. When the crushing plates 3704 rotate, they can crush the raised soil blocks, thereby preventing the protective net from being broken due to the raised soil blocks when laying the protective net.

[0053] When the protective net is laid, the end of the net can be cut and then nailed to the edge of the slope. At this time, seeds need to be sown on the slope surface.

[0054] The driving mechanism that drives the gear 371 to rotate can be reversed, and the hydraulic cylinder 32 can be activated to expand outward at the same time, so that the bottom arc box 42 and the arc outer plate 4681 can move in opposite directions at the same time. The specific movement steps are opposite to the steps described above and will not be described in detail in this solution.

[0055] When the device is driven in reverse, the second drop-out port 4682 on the front side can be fitted with the first drop-out port 44 on the front side, and then the lining machine can be moved back to the initial position. During this process, the seeds placed in the front mounting groove 43 can fall to the slope surface, eliminating the need for manual sowing. The device can be switched between laying the protective net and sowing seeds, thereby improving the versatility of the device.

[0056] The driving mechanism mentioned above is composed of a servo motor in the prior art, and its specific operating principle is as follows:

[0057] Control signal input: The servo motor's control system receives an input signal from the controller, which is usually a set target value for position, speed or torque.

[0058] Sensor feedback: Servo motors are typically equipped with internal sensors, such as encoders or resolvers, to monitor the motor's output status in real time, including parameters such as speed and position. These sensors provide feedback to the control system regarding the motor's current operating status.

[0059] Error detection and adjustment: The control system compares the input target value with the feedback signal and calculates the system error. If there is a deviation, such as the motor position deviating from the target position, the control system automatically adjusts the motor's operating state based on the error, reducing the error by changing control parameters such as current and speed.

[0060] Motor Drive: The drive unit of a servo motor drives the motor according to control signals. Two common types of servo motors are DC servo motors and AC servo motors. The drive unit primarily regulates the motor's torque and speed by controlling the current and voltage supplied to the motor.

[0061] Closed-loop control: Servo motors use a closed-loop control system that ensures the motor output is always close to the set target through continuous adjustment and feedback to achieve control.

[0062] Therefore, the driving mechanism described above is a conventional design in the prior art, and its specific installation method, circuit connection method, and control method are all conventional designs. This solution will not be elaborated in detail.

[0063] It should be noted that the specific installation method, circuit connection method and control method of the hydraulic cylinder 32 and the motor 3701 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0064] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
