Description

Technical Field

[0001] This invention relates to the field of dust control netting installation technology, specifically to a dust control netting installation device and its usage method for construction site earthwork. Background Technology

[0002] Earthwork at construction sites refers to the total amount of sand, soil, and other materials excavated during the construction of houses, roads, and bridges. To reduce dust pollution, the surface of the earthwork needs to be covered with dust-proof netting. Currently, stones or bricks are usually used to weigh down the dust-proof netting to secure it.

[0003] However, using stones or bricks to fix dust control nets on earthwork slopes is not stable. During use, there is a risk that the stones or bricks will roll down, causing the dust control nets to be lifted or blown away by the wind, reducing the stability of the dust control nets.

[0004] To address this, anchor bolts and similar structures are currently used to fix dust control netting on earthwork slopes. When the anchor bolt is inserted into the earthwork slope, the head of the anchor bolt presses the dust control netting onto the slope, eliminating the risk of the anchor bolt rolling off and reducing the risk of the dust control netting being lifted or blown away by strong winds, thus improving the stability of the dust control netting installation.

[0005] For example, the patent with publication number CN209647180U discloses a "dustproof net fixing device". This device places a pressure strip on the surface of the dustproof net, then uses a rod to penetrate the pressure strip and inserts the rod into the ground. The pressure strip presses the dustproof net onto the slope, which can improve the stability of the dustproof net.

[0006] While the aforementioned method of fixing dust control nets with anchor bolts or chisels can improve the stability of the dust control nets, it requires workers to manually install them, which increases the labor intensity of workers and reduces work efficiency. Summary of the Invention

[0007] This invention addresses the aforementioned shortcomings of existing technologies by providing a construction site dust control netting installation device and method. This invention enables automated anchor bolt installation, which helps reduce the labor intensity of workers and improves work efficiency.

[0008] To achieve the above objectives, the present invention provides the following technical solution: A construction site earthwork dust control netting laying device includes anchor rods for fixing the dust control netting to the slope of the earthwork, and a support frame extending parallel to the slope of the earthwork. The support frame is equipped with a movable cylinder, and several anchor rods are stacked inside the movable cylinder. The movable cylinder moves along the extension direction of the support frame. The movable cylinder is equipped with an anchor plug, which is used to insert the last anchor rod inside the movable cylinder into the slope of the earthwork, so that the dustproof net is fixed to the slope of the earthwork by the anchor rod; The support frame has several positioning detection elements along its extension direction. The positioning detection elements, the moving cylinder, and the installation plug are all electrically connected to the control module. Whenever the moving cylinder moves to the position of the positioning detection component, the control module receives the detection signal from the positioning detection component. The control module controls the moving cylinder to stop and controls the installation plug to insert the last anchor rod inside the moving cylinder into the dust control net and the slope of the earthwork in sequence. The head of the anchor rod presses the dust control net onto the slope of the earthwork.

[0009] Furthermore, the mounting device includes a telescopic rod, which is electrically connected to the control module, and both ends of the telescopic rod are hinged with swing arms. The middle parts of both swing arms are rotatably connected to the moving cylinder; The top of each of the two swing arms is hinged to an upper connecting rod, and the other end of the upper connecting rod is hinged to an upper baffle. The upper baffle is horizontally slidably connected to the upper opening on the moving cylinder. Both swing arms are hinged to a lower connecting rod at the bottom, and the other end of the lower connecting rod is hinged to a lower baffle. The lower baffle is horizontally slidably connected to the lower opening on the moving cylinder, and the upper opening and the lower opening are connected through the middle opening. Below each of the two upper baffles is a slider. The two sliders are connected by a pusher frame. The pusher frame is vertically slidably connected to the moving cylinder by a pusher telescopic rod. The pusher telescopic rod is electrically connected to the control module. A push plate is horizontally slidably connected to the slider. The push plate is located in the middle opening. A vertical rod is provided on the push plate. The vertical rod is vertically slidably connected to the upper baffle. The bottom of the movable cylinder is provided with a clearance opening along the extension direction of the support frame. The clearance opening is used to avoid the head of the anchor rod that has been inserted into the slope of the earthwork.

[0010] Furthermore, the top of the moving cylinder is provided with a feeding component, and the top of the feeding component is provided with a hopper. The hopper is connected to the moving cylinder through a connecting frame. The hopper is used to hold several anchor rods. The feeding component is used to replenish the anchor rods in the hopper into the moving cylinder. An anchor rod detection component is provided in the upper part of the moving cylinder. Both the anchor rod detection component and the feeding component are electrically connected to the control module. When the anchor bolt detection component does not detect an anchor bolt, the control module controls the feeding component to add anchor bolts into the moving cylinder. When the anchor bolt detection component detects an anchor bolt, the control module controls the feeding component to stop feeding anchor bolts into the moving cylinder.

[0011] Furthermore, the feeding component includes a feeding telescopic rod, which is mounted on the hopper and electrically connected to the control module. The output end of the feeding telescopic rod is provided with a first sealing plate, and the first sealing plate has a second sealing plate at the end opposite to the feeding telescopic rod. The second sealing plate has a first through hole, and two opening and closing plates are symmetrically slidably connected to the bottom surface of the second sealing plate. The two opening and closing plates each have a semi-circular hole on the side closest to each other, and the two semi-circular holes are used to combine to form a second through hole, which communicates with the first through hole. The bottom surface of the two opening and closing plates is provided with a guide pin and a guide rail, which are connected to the hopper. The guide pin and the guide rail are slidably engaged, and the two guide rails are symmetrically arranged. The distance between the two guide rails is the smallest at the end closest to the feeding telescopic rod, and the distance between the two guide rails is the largest at the end furthest from the feeding telescopic rod. When the feeding telescopic rod is in the shortened state, the second sealing plate is located at the bottom of the hopper, the two opening and closing plates are in the spliced ​​state, and one of the anchor rods in the hopper is inserted into the first through hole and the second through hole from top to bottom, with the head of the anchor rod resting on the top surface of the opening and closing plate. When the feeding telescopic rod is in the extended state, the first sealing plate is located at the bottom of the hopper, the second sealing plate is located above the moving cylinder, the two opening and closing plates are in the separated state, and the anchor rod falls into the moving cylinder.

[0012] Furthermore, the movable cylinder includes a cylinder body and a power structure disposed on the cylinder body. The cylinder body is slidably connected to the support frame. The power structure is used to drive the cylinder body to move along the extension direction of the support frame. The cylinder body is provided with the installation plug.

[0013] Furthermore, the power structure includes a motor, a gear, and a rack. The motor is mounted on the cylinder, and the output end of the motor is equipped with a gear. The rack is mounted on the support frame, and the gear and rack cooperate with each other.

[0014] Furthermore, the hopper is provided with a mounting base, and a sliding rod is slidably connected inside the mounting base. The upper end of the sliding rod is bent into the inside of the hopper to form a clearing rod, which is used to tap the inner wall of the hopper. The lower end of the sliding rod is provided with a contact rod, which slides in engagement with the teeth of the rack. The teeth of the rack are set downwards. The mounting base is provided with an elastic element, which is used to push the sliding rod upwards so that the contact rod and the teeth of the rack remain in contact.

[0015] Furthermore, a guide frame is provided on one side of the support frame, which is used to guide the dustproof net roll to roll along the slope of the earthwork. The dustproof net roll includes a roller and the dustproof net wound on the roller.

[0016] A method for using a construction site earthwork dust control netting laying device, based on the aforementioned construction site earthwork dust control netting laying device, includes the following steps: S1. Use the guide frame to lay the first dustproof net on the slope of the earthwork; S2. Move the support frame and guide frame; S3. Using a guide frame, lay a dustproof net on the slope of the earthwork, with the sides of two adjacent dustproof nets overlapping. At the same time, the control module controls the moving cylinder to move along the extension direction of the support frame. Whenever the moving cylinder passes the positioning detection piece, the control module controls the moving cylinder to stop and controls the installation plug to insert the last anchor rod in the moving cylinder into the side of the first dustproof net and the slope of the earthwork in sequence. S4. Continue moving the support frame and guide frame; S5. Use the guide frame to lay a dustproof net on the slope of the earthwork, with the sides of two adjacent dustproof nets overlapping; at the same time, the control module controls the moving cylinder to move in the opposite direction along the extension direction of the support frame. Whenever the moving cylinder passes the positioning detection piece, the control module controls the moving cylinder to stop, and controls the installation plug to insert the last anchor rod in the moving cylinder into the overlapping position of the two adjacent dustproof nets and the slope of the earthwork in sequence. S6. Repeat steps S4 and S5 to lay the required number of dustproof nets and fix the overlapping positions on the slope of the earthwork. S7. Continue moving the support frame and guide frame until the support frame is above the side of the last dustproof net. The control module controls the moving cylinder to move along the extension direction of the support frame. Whenever the moving cylinder passes the positioning detection piece, the control module controls the moving cylinder to stop and controls the plug to insert the last anchor rod in the moving cylinder into the side of the last dustproof net and the slope of the earthwork in sequence.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting a movable cylinder and several positioning detection components on the support frame, and setting an installation plug for inserting anchor rods on the movable cylinder, when the movable cylinder moves to the position of the positioning detection components, the installation plug will insert the anchor rods inside the movable cylinder downwards. The anchor rods will fix the dustproof net to the slope of the earthwork. Because the anchor rods are inserted into the slope of the earthwork, the reliability and stability of fixing the dustproof net can be improved.

[0018] 2. By electrically connecting the moving cylinder and the installation plug to the control module, the anchor bolts can be automatically installed without the need for manual installation by workers, which helps to reduce the labor intensity of workers and improve work efficiency.

[0019] 3. In the installation unit, the opening and closing of the two upper baffles, two lower baffles, and two push plates are powered by an installation telescopic rod, and the raising and lowering of the two push plates are powered by a pushing telescopic rod. This enables the installation of the last anchor bolt inside the moving cylinder, the downward progressive replenishment of anchor bolts within the moving cylinder, and the sealing action of the moving cylinder. The structure is compact and reliable. Furthermore, it reduces the number of power sources, thus saving energy and costs.

[0020] 4. By installing a feeding component and a hopper above the moving cylinder, and an anchor bolt detection component at the top of the moving cylinder, and by electrically connecting the anchor bolt detection component and the feeding component to the control module, automatic feeding into the moving cylinder can be achieved without manual feeding, which helps to further reduce the labor intensity of workers; moreover, it is conducive to timely feeding into the moving cylinder, avoiding delays in the fixing of the dustproof net, and improving the efficiency of fixing the dustproof net.

[0021] 5. The material replenishment component only requires one power source, the material replenishment telescopic rod, to realize the translation and release action of the anchor bolt. The structure is compact and reliable, which helps to save energy.

[0022] 6. By setting up a mounting base, sliding rod, unblocking rod, contact rod, and elastic element, the tooth undulation characteristics of the rack and pinion and the elastic force of the elastic element can be used to drive the sliding rod to slide up and down in the mounting base. This allows the sliding rod to drive the unblocking rod to continuously strike the inner wall of the hopper. The vibration of the inner wall of the hopper and the up and down movement of the unblocking rod are used to unblock the anchor rods in the hopper, reducing the chance of the anchor rods in the hopper getting stuck together, so as to ensure the reliability of feeding.

[0023] 7. The unblocking structure formed by the mounting base, slide bar, unblocking rod, contact rod, and elastic element utilizes the tooth undulation characteristics of the rack and pinion and the elastic force of the elastic element, so no additional power source is required, which helps to save energy and reduce costs.

[0024] 8. The guide frame can prevent the dustproof net from tilting when laying it, which helps to improve the neatness of the laying and thus improves the accuracy of the anchor bolts in fixing the dustproof net to the earthwork slope.

[0025] 9. Since the movable cylinder equipped with anchor bolts moves on the support frame and the dustproof net roll moves on the guide frame, the operation of laying the dustproof net and the operation of fixing it with anchor bolts can be carried out simultaneously, which can further improve the efficiency of laying and fixing the dustproof net.

Detailed Implementation

[0028] 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, not all, of the embodiments of the present invention. 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.

[0029] Example 1: A construction site dust control netting installation device, see [link / reference] Figure 1 and Figure 2 It includes a support frame 3, the extension direction of which is parallel to the slope surface 1 of the earthwork.

[0030] See Figure 1 and Figure 2 The support frame 3 is equipped with a movable cylinder 4.

[0031] See Figure 3 The movable cylinder 4 includes a cylinder body 41 and a power structure.

[0032] See Figure 2 and Figure 3 The axis of cylinder 41 is perpendicular to the slope 1 of the earthwork. See also Figure 9 Inside the cylinder 41, several anchor rods 5 are stacked. The anchor rods 5 are used to fix the dustproof net 21 to the slope 1 of the earthwork.

[0033] The power structure is used to drive the cylinder 41 to move along the extension direction of the support frame 3. See also Figure 3 and Figure 7 The power structure includes a motor 421, a gear 422, and a rack 423. See also... Figure 7 The motor 421 is fixedly mounted on the outer wall of the cylinder 41, and a gear 422 is fixedly mounted on the output end of the motor 421. (See also...) Figure 3 The gear 422 meshes with the rack 423 fixedly mounted on the support frame 3. The rack 423 extends parallel to the slope 1 of the earthwork. The cylinder 41 slides along the extension direction of the support frame 3.

[0034] The working principle of the movable tube 4 is as follows: See Figure 3 When the motor 421 drives the gear 422 to rotate forward, the gear 422 drives the cylinder 41 to move from bottom to top along the rack 423; when the motor 421 drives the gear 422 to rotate in reverse, the gear 422 drives the cylinder 41 to move from top to bottom along the rack 423.

[0035] See Figure 7 and Figure 8 An anchor plug 6 is installed on the cylinder 41. The anchor plug 6 is used to insert the last anchor rod 5 inside the cylinder 41 into the slope 1 of the earthwork, so that the dustproof net 21 is fixed to the slope 1 of the earthwork by the anchor rod 5. In this embodiment, counting backwards means counting from bottom to top.

[0036] See Figure 7 The mounting plug 6 includes a telescopic rod 61. The telescopic rod 61 is made of one of three types: hydraulic cylinder, pneumatic cylinder, or electric cylinder. Both ends of the telescopic rod 61 are hinged to the top of the swing arm 62.

[0037] See Figure 8 Each of the two swing arms 62 is also hinged to an upper connecting rod 63 at its top, and the other end of the upper connecting rod 63 is hinged to an upper baffle 64. See also Figure 7 The upper baffle 64 and the upper opening 411 on the cylinder 41 are horizontally slidably fitted.

[0038] See Figure 7 The middle parts of the two swing arms 62 are rotatably connected to the rotating seat 414, which is fixedly installed on the outer wall of the cylinder 41.

[0039] See Figure 8 Both swing arms 62 have a lower connecting rod 69 hinged to their bottoms. The other end of the lower connecting rod 69 is hinged to a lower baffle 610. The lower baffle 610 is horizontally slidingly engaged with the lower opening 413 at the bottom of the cylinder 41. The upper opening 411 and the lower opening 413 are connected through the middle opening 412.

[0040] See Figure 8Below each of the two upper baffles 64, there is a slider 67. The two sliders 67 are fixedly installed on the same pusher frame 65. A pusher telescopic rod 66 is fixedly installed on the outer wall of the cylinder 41. The pusher telescopic rod 66 is one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. The output end of the pusher telescopic rod 66 is fixedly installed together with the pusher frame 65. When the output end of the pusher telescopic rod 66 extends or retracts, it can push the pusher frame 65 to move up and down. The pusher frame 65 drives the two sliders 67 to slide up and down against the outer wall of the cylinder 41.

[0041] See Figure 8 Both sliders 67 have dovetail grooves on their top surfaces. A push plate 68 is horizontally slidably fitted inside the dovetail groove. The push plate is located inside the middle opening 412. A vertical rod 681 is fixedly installed on the push plate 68. The vertical rod 681 is vertically slidably fitted with the vertical hole opened in the upper baffle 64.

[0042] The working principle of AnPlug-in 6 is as follows: See Figure 7 and Figure 8 When the telescopic rod 61 is in its longest position and the push telescopic rod 66 is in its shortest position, the distance between the top ends of the two swing arms 62 is at its maximum, and the distance between the bottom ends of the two swing arms 62 is at its minimum; and, see also Figure 9 The two upper baffles 64 do not cover the inner cavity of the cylinder 41, and the two push plates 68 do not cover the inner cavity of the cylinder 41 either. Both push plates 68 are in contact with the bottom surface of the upper baffles 64, and the two lower baffles 610 are in the state of covering the bottom of the cylinder 41. At this time, the last anchor rod 5 falls on the lower baffle 610, and the second to last anchor rod 5 falls on the top of the last anchor rod 5.

[0043] See Figures 9 to 10 As the state changes, when the inserted telescopic rod 61 gradually shortens and the pushed telescopic rod 66 remains at its shortest state, on the one hand, the distance between the top ends of the two swing arms 62 gradually decreases, causing the two upper baffles 64 to gradually approach each other. Since the upper baffles 64 cooperate with the push plates 68 through the vertical rods 681, the two push plates 68 move horizontally together with the two upper baffles 64, causing the two push plates 68 to gradually approach each other. On the other hand, the distance between the bottom ends of the two swing arms 62 gradually increases, and the two lower baffles 610 gradually separate from the bottom of the open cylinder 41, causing the penultimate anchor rod 5 to fall onto the slope 1 under its own weight. However, the penultimate anchor rod 5 has not yet been inserted into the slope 1 of the earthwork. At the same time, the penultimate anchor rod 5 also moves down under its own weight. The gap between the two upper baffles 64 and the gap between the two push plates 68 allow the rod part of the penultimate anchor rod 5 to pass through, but the two upper baffles 64 block the head of the penultimate anchor rod 5.

[0044] See Figures 10 to 11As the state changes, when the inserted telescopic rod 61 is in its shortest state and the pushing telescopic rod 66 gradually extends, the pushing telescopic rod 66 pushes the pushing frame 65 downward. The pushing frame 65 drives the two sliders 67 to move downward, the two sliders 67 drive the two push plates 68 to move downward, and the push plates 68 drive the vertical rod 681 to move downward. The vertical rod 681 slides downward in the vertical hole of the upper baffle 64. The two push plates 68 push the penultimate anchor rod 5 to be inserted into the mesh of the dustproof net 21 and the slope 1 of the earthwork. At the same time, the head of the penultimate anchor rod 5 falls on the top surface of the upper baffle 64, and the upper baffle 64 prevents the penultimate anchor rod 5 from falling completely.

[0045] See Figures 11 to 12 As the state changes, the pusher telescopic rod 66 gradually shortens and returns to its original position, causing the two push plates 68 to move upward and reset to abut the bottom surface of the upper baffle 64. Furthermore, a clearance opening 415 is provided at the bottom of the cylinder 41 along the extension direction of the support frame 3. When the anchor rod 5 is inserted into the slope surface 1 of the earthen slope, the cylinder 41 needs to move along the extension direction of the support frame 3 so that the head of the anchor rod 5 exits the cylinder 41 through the clearance opening 415. The clearance opening 415 ensures that the cylinder 41 does not obstruct the movement of the support frame 3 along its extension direction.

[0046] See Figures 12 to 13 As the telescopic rod 61 gradually extends and resets, the two lower baffles 610 gradually approach each other, causing the bottom of the cylinder 41 to be blocked by the two lower baffles 610. The two upper baffles 64 gradually separate, causing the inner cavity of the cylinder 41 to reopen, allowing the second-to-last anchor rod 5 to fall completely on the lower baffle 610. The other anchor rods 5 inside the cylinder 41 fall down in sequence, leaving a space for an anchor rod 5 in the upper part of the cylinder 41 to be replenished.

[0047] Based on the working principle of AnPlug-in 6 described above, it can be seen that AnPlug-in 6 has the following advantages: In the insert 6, the opening and closing of the two upper baffles 64, the two lower baffles 610, and the two push plates 68 are powered by an insert telescopic rod 61, and the raising and lowering of the two push plates 68 are powered by a push telescopic rod 66. This enables the insertion of the penultimate anchor rod 5 inside the cylinder 41, the downward replenishment of the anchor rod 5 inside the cylinder 41, and the sealing action of the cylinder 41. The structure is compact and reliable. Furthermore, it reduces the number of power sources, thus saving energy and costs.

[0048] See Figure 5 and Figure 6 Several positioning detection elements 31 are installed along the extension direction of the support frame 3. The positioning detection elements 31 can be one of an infrared sensor, a photoelectric sensor, or a micro switch. (See also...) Figure 4 The positioning detection component 31, motor 421, insertion telescopic rod 61 and pushing telescopic rod 66 are all electrically connected to the control module 7.

[0049] See Figure 1 A guide frame 8 is fixedly installed on one side of the support frame 3. (See also...) Figure 20 and Figure 21 The guide frame 8 has an inlet 81 at its top and an outlet 83 at its bottom. The inlet 81 is connected to the outlet 83 via a guide channel 82. See also Figure 22 The dustproof net roll 2 includes a roller 22 and a dustproof net 21 wound on the roller 22. The distance between the support frame 3 and the guide frame 8 is less than the width of the dustproof net 21 so that adjacent dustproof nets 21 can overlap when laid.

[0050] The working principle of using the guide frame 8 to lay the dustproof net 21 is as follows: First, insert the roller 22 of the dustproof net roll 2 into the inlet 81, and use bricks to press the starting end of the dustproof net 21 onto the top of the slope 1; then push the dustproof net roll 2 down, so that the dustproof net roll 2 rolls down along the guide channel 82. The dustproof net roll 2 rolls and unfolds as it rolls, so that the dustproof net 21 is laid on the slope 1; when the dustproof net roll 2 rolls to the bottom of the guide frame 8, take the roller 22 out from the outlet 83, and use bricks to press the end of the dustproof net 21 onto the bottom of the slope 1.

[0051] The working principle of this embodiment 1 is as follows: Using a guide frame 8, dust control netting 21 is laid on the slope 1 of the earthwork, with the overlap length of two adjacent dust control nets 21 being no less than 50 cm. Anchor bolts 5 are needed to fix the side of the first dust control netting 21, the side of the last dust control netting 21, and the overlap position of two adjacent dust control nets 21.

[0052] When using anchor bolts 5 to fix the side or overlapping position of the dustproof net 21, the moving cylinder 4 moves from the upper end to the lower end of the support frame 3, or from the lower end to the upper end of the support frame 3. Since the support frame 3 has several positioning detection elements 31 in the extension direction, anchor bolts 5 are needed to fix the dustproof net 21 at the position corresponding to the positioning detection elements 31.

[0053] Whenever the moving cylinder 4 moves to the position of the positioning detection element 31, the positioning detection element 31 transmits a detection signal to the control module 7. Upon receiving the detection signal from the positioning detection element 31, the control module 7 first controls the moving cylinder 4 to stop moving; then, the control module 7 controls the insertion telescopic rod 61 in the mounting plug 6 to shorten from its long position, causing the last anchor 5 to fall onto the slope 1 of the earthwork; next, the control module 7 controls the pushing telescopic rod 66 in the mounting plug 6 to extend from its short position, causing the push plate 68 to push the last anchor 5 onto the slope 1 of the earthwork. Anchor rods 5 are inserted sequentially into the mesh of the dustproof net 21 and into the slope 1 of the earthwork. After installation, the control module 7 controls the push telescopic rod 66 to return from its long to short position. Then, the control module 7 controls the moving cylinder 4 to continue moving, so that the head of the anchor rod 5 that has been inserted into the slope 1 exits the moving cylinder 4. The control module 7 then controls the installation telescopic rod 61 to return from its short to long position, so that the second to last anchor rod 5 in the moving cylinder 4 falls on the lower baffle 610, and the other anchor rods 5 move downwards to fill the gap, ready for the next installation of anchor rods 5.

[0054] Based on the working principle described above in Embodiment 1, it can be seen that Embodiment 1 has the following effects: By setting a movable cylinder 4 and several positioning detection elements 31 on the support frame 3, and setting an installation plug 6 for inserting anchor rods 5 on the movable cylinder 4, when the movable cylinder 4 moves to the position of the positioning detection element 31, the installation plug 6 inserts the anchor rods 5 inside the movable cylinder 4 downwards, and the anchor rods 5 fix the dustproof net 21 to the slope 1 of the earthwork. Because the anchor rods 5 are inserted into the slope 1 of the earthwork, the reliability and stability of fixing the dustproof net 21 can be improved.

[0055] Furthermore, by electrically connecting the motor 421 inside the moving cylinder 4, the insertion telescopic rod 61 in the insertion plug 6, and the pushing telescopic rod 66 to the control module 7, the automatic insertion of the anchor bolt 5 can be achieved without manual insertion by workers, which helps to reduce the labor intensity of workers and improve work efficiency.

[0056] In addition, the guide frame 8 can prevent the dustproof net 21 from tilting when laying it, which helps to improve the neatness of the laying and thus improves the accuracy of the anchor rod 5 in fixing the dustproof net 21 to the earthwork slope 1.

[0057] Example 2: A method for using a construction site earthwork dust control netting laying device, based on the construction site earthwork dust control netting laying device of Embodiment 1, includes the following steps: S1. Workers place the support frame 3 and guide frame 8 on the slope 1 of the earthwork, and lay the dustproof net 21 from left to right on the slope 1 of the earthwork.

[0058] S2. The worker first inserts the roller 22 of a dustproof net roll 2 into the inlet 81 of the guide frame 8, and uses bricks or stones to press the starting end of the dustproof net 21 onto the top of the slope 1; then pushes the dustproof net roll 2 down, so that the dustproof net roll 2 rolls down along the guide channel 82. The dustproof net roll 2 rolls and unfolds as it rolls, so that the dustproof net 21 is laid on the slope 1 of the earthwork; when the dustproof net roll 2 rolls to the bottom of the guide frame 8, the roller 22 is taken out from the outlet 83, and bricks are used to press the end of the dustproof net 21 onto the bottom of the slope 1, thus completing the laying of a dustproof net 21.

[0059] S3. Use a tractor to pull the guide frame 8 to the right, so that the assembled support frame 3 and guide frame 8 move to the right together; or, the worker can manually push the support frame 3 to move the assembled support frame 3 and guide frame 8 to the right together. Stop moving when the support frame 3 moves to above the left side of the first dustproof net 21. Since the distance between the support frame 3 and the guide frame 8 is less than the width of the dustproof net 21, adjacent dustproof nets 21 can overlap when laying the next dustproof net 21.

[0060] S4. Repeat step S2 to lay the second dustproof net 21, with the two adjacent dustproof nets 21 overlapping.

[0061] Meanwhile, control module 7 controls the moving cylinder 4 to move along the extension direction of support frame 3. Whenever the moving cylinder 4 passes the positioning detection element 31, control module 7 receives the detection signal from the positioning detection element 31. First, control module 7 controls the moving cylinder 4 to stop moving; then, control module 7 controls the insertion telescopic rod 61 in the installation plug 6 to shorten from its long position, so that the last anchor rod 5 falls onto the slope 1 of the earthwork; next, control module 7 controls the pushing telescopic rod 66 in the installation plug 6 to extend from its short position, so that the push plate 68 inserts the last anchor rod 5 in sequence. The first dustproof net 21 is inserted into the mesh on the left side and into the slope 1 of the earthwork. After insertion, the control module 7 controls the push telescopic rod 66 to return from its long shortening to its original position. Then, the control module 7 controls the moving cylinder 4 to continue moving, causing the head of the anchor rod 5 that has been inserted into the slope 1 to exit the moving cylinder 4. The control module 7 then controls the insertion telescopic rod 61 to return from its short extension to its original position, causing the second-to-last anchor rod 5 in the moving cylinder 4 to fall onto the lower baffle 610 and become the new first-to-last anchor rod 5. The other anchor rods 5 move downwards to fill the gaps, ready for the next insertion operation. This continues until all the corresponding positions of the positioning detection pieces 31 in the extension direction of the support frame 3 have been inserted.

[0062] S5. Continue to move the support frame 3 and guide frame 8 to the right. When the support frame 3 moves above the overlapping position of the two adjacent dustproof nets 21, stop moving.

[0063] S6. Repeat step S2 to lay the next dustproof net 21, with adjacent dustproof nets 21 overlapping.

[0064] Meanwhile, control module 7 controls the moving cylinder 4 to move in the opposite direction along the support frame 3. Whenever the moving cylinder passes the positioning detection element 31, control module 7 receives the detection signal from the positioning detection element 31. First, control module 7 controls the moving cylinder 4 to stop moving; then, control module 7 controls the insertion telescopic rod 61 in the installation plug 6 to shorten from its long position, so that the last anchor rod 5 falls onto the slope 1 of the earthwork; next, control module 7 controls the pushing telescopic rod 66 in the installation plug 6 to extend from its short position, so that the push plate 68 inserts the last anchor rod 5 into the adjacent... The mesh openings at the overlapping positions of the two dust control nets 21 and the interior of the slope 1 of the earthwork; after installation, the control module 7 controls the push telescopic rod 66 to return from its long shortening to its original position; then, the control module 7 controls the moving cylinder 4 to continue moving, causing the head of the anchor rod 5 already inserted into the slope 1 to exit the moving cylinder 4, and the control module 7 then controls the installation telescopic rod 61 to return from its short extension to its original position, so that the second-to-last anchor rod 5 in the moving cylinder 4 falls onto the lower baffle 610 to become the new first-to-last anchor rod 5, and the other anchor rods 5 move downwards to fill the gaps, ready for the next installation operation. This continues until all the corresponding positions of the positioning detection pieces 31 in the extension direction of the support frame 3 have been installed.

[0065] S7. Repeat steps S5 and S6 until the required number of dust nets 21 are laid and fixed on the earthwork slope 1.

[0066] S8. For the right side of the last dustproof net 21, anchor rods 5 are also needed for fixation. Therefore, continue to move the support frame 3 and guide frame 8 to the right until the support frame 3 moves above the right side of the last dustproof net 21. The control module 7 controls the moving cylinder 4 to move along the extension direction of the support frame 3. Whenever the moving cylinder passes the positioning detection element 31, the control module 7 receives the detection signal from the positioning detection element 31. First, the control module 7 controls the moving cylinder 4 to stop moving; then, the control module 7 controls the insertion telescopic rod 61 in the installation plug 6 to shorten from its long position, so that the last anchor rod 5 falls onto the slope 1 of the earthwork; next, the control module 7 controls the pushing telescopic rod 66 in the installation plug 6 to extend from its short position, so that the push plate 68 inserts the last anchor rod 5 into the last one in sequence. The dustproof netting 21 has mesh openings on the right side and is installed inside the slope 1 of the earthwork. After installation, the control module 7 controls the push telescopic rod 66 to return from its long shortening to its original position. Then, the control module 7 controls the moving cylinder 4 to continue moving, causing the head of the anchor rod 5 that has been inserted into the slope 1 to exit the moving cylinder 4. The control module 7 then controls the installation telescopic rod 61 to return from its short extension to its original position, causing the second-to-last anchor rod 5 inside the moving cylinder 4 to fall onto the lower baffle 610 and become the new first-to-last anchor rod 5. The other anchor rods 5 move downwards to fill the gaps, ready for the next installation operation. This continues until all the positioning detection pieces 31 in the extension direction of the support frame 3 have been installed.

[0067] S9. Remove the support frame 3 and guide frame 8 from the slope 1 of the earthwork.

[0068] Based on the above-described method of use in Embodiment 2, it can be seen that the method of use in Embodiment 2 has the following advantages: By setting a movable cylinder 4 and several positioning detection elements 31 on the support frame 3, and setting an installation plug 6 for inserting anchor rods 5 on the movable cylinder 4, when the movable cylinder 4 moves to the position of the positioning detection element 31, the installation plug 6 inserts the anchor rods 5 inside the movable cylinder 4 downwards, and the anchor rods 5 fix the dustproof net 21 to the slope 1 of the earthwork. Because the anchor rods 5 are inserted into the slope 1 of the earthwork, the reliability and stability of fixing the dustproof net 21 can be improved.

[0069] Furthermore, since the movable cylinder 4 equipped with anchor bolts 5 moves on the support frame 3 and the dustproof net roll 2 moves on the guide frame 8, the operation of laying the dustproof net 21 and the operation of fixing it with anchor bolts 5 can be performed simultaneously. For example, in steps S4 and S6, the operation of laying the dustproof net 21 and the operation of fixing it with anchor bolts 5 are performed simultaneously. Therefore, the efficiency of laying and fixing the dustproof net 21 can be further improved.

[0070] Example 3: This embodiment 3 is an improvement upon embodiment 1: See Figure 3 A feeding component 9 is provided above the cylinder 41, and a hopper 10 is provided above the feeding component 9. The hopper 10 is fixedly connected to the cylinder 41 through a connecting frame 101. The hopper 10 is used to hold a number of anchor rods 5, and the feeding component 9 is used to replenish the anchor rods 5 in the hopper 10 into the cylinder 41.

[0071] See Figure 13 An anchor bolt detection component 416 is fixedly installed on the upper part of the cylinder 41. The anchor bolt detection component 416 adopts one of the following: infrared sensor, photoelectric sensor, or micro switch. Both the anchor bolt detection component 416 and the feeding component 9 are electrically connected to the control module 7.

[0072] The working principle of this embodiment 3 is as follows: See Figure 13 When the upper part of the cylinder 41 is empty enough to fill the space of an anchor rod 5, the anchor rod detection component 416 located at the upper part of the cylinder 41 does not detect the anchor rod 5. At this time, the control module 7 controls the feeding component 9 to add anchor rods 5 into the cylinder 41. When the anchor rod detection component 416 detects the anchor rod 5, it means that no feeding is needed inside the cylinder 41, and the control module 7 controls the feeding component 9 to stop adding anchor rods 5 into the cylinder 41.

[0073] Based on the working principle described above in Embodiment 3, it can be seen that Embodiment 3 has the following effects: By setting a feeding component 9 and a hopper 10 above the cylinder 41, setting an anchor bolt detection component 416 on the upper part of the cylinder 41, and electrically connecting the anchor bolt detection component 416 and the feeding component 9 to the control module 7, automatic feeding operation into the moving cylinder 4 can be realized without manual feeding, which is conducive to further reducing the labor intensity of workers; and it is also conducive to timely feeding into the moving cylinder 4, avoiding delays in the fixing operation of the dustproof net 21, and improving the efficiency of fixing the dustproof net 21.

[0074] This embodiment 3 provides a specific structure for the feeding component 9: See Figure 17 The feeding component 9 includes a feeding telescopic rod 91, which is one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. The feeding telescopic rod 91 is fixedly installed on the hopper 10. A first sealing plate 92 is fixedly installed at the output end of the feeding telescopic rod 91, and a second sealing plate 93 is fixedly installed at the end of the first sealing plate 92 opposite to the feeding telescopic rod 91. See also Figure 4 The material replenishment telescopic rod 91 is electrically connected to the control module 7.

[0075] See Figure 16 The second sealing plate 93 is provided with a first through hole 931. The first through hole 931 is large enough so that the anchor rod 5 can fall out of the first through hole 931 intact.

[0076] See Figure 15 and Figure 18 The bottom surface of the second sealing plate 93 is symmetrically slidably connected to two opening and closing plates 94. (See also...) Figure 16 Both hinged plates 94 have semi-circular holes 941 on the side closest to each other. When the two hinged plates 94 are joined together, the two semi-circular holes 941 are combined to form a second through hole. The second through hole is connected to the first through hole 931. The diameter of the second through hole only allows the rod part of the anchor rod 5 to pass through, so that the head of the anchor rod 5 can fall on the top surface of the hinged plate 94.

[0077] See Figure 18 Guide pins 942 are welded and fixed to the bottom surface of both hinged plates 94. (See also...) Figure 15 Two guide rails 95 are fixedly installed at the bottom of the hopper 10. The two guide rails 95 are symmetrically arranged. A guide pin 942 slides with one guide rail 95. The distance between the two guide rails 95 is the smallest at the end closer to the feeding telescopic rod 91, and the distance between the two guide rails 95 is the largest at the end farther away from the feeding telescopic rod 91.

[0078] The working principle of the replenishment component 9 is as follows: See Figure 17 and Figure 18The initial state of the feeding telescopic rod 91 is its shortest state. When the feeding telescopic rod 91 is in its shortest state, the second sealing plate 93 is located at the bottom of the hopper 10, and the two opening and closing plates 94 are in a spliced ​​state. The rod of one of the anchor rods 5 in the hopper 10 is inserted into the first through hole 931 and the second through hole from top to bottom, and the head of this anchor rod 5 rests on the top surface of the opening and closing plate 94.

[0079] When the anchor bolt detection component 416 on the upper part of the cylinder 41 does not detect the anchor bolt 5, the control module 7 controls the feeding telescopic rod 91 to extend from its shortest state to its longest state. During the extension of the feeding telescopic rod 91, the feeding telescopic rod 91 pushes the first sealing plate 92 and the second sealing plate 93 to translate, so that the second sealing plate 93 drives the anchor bolt 5 inserted in the first through hole 931 and the second through hole to gradually translate to the top of the cylinder 41. The two opening and closing plates 94 at the bottom of the second sealing plate 93 gradually separate under the guidance of the guide rail 95, and the first sealing plate 92 gradually translates to the bottom of the hopper 10.

[0080] When the replenishing telescopic rod 91 is in its longest state, the first sealing plate 92 is located at the bottom of the hopper 10, so that the anchor rod 5 inside the hopper 10 will not fall out. Furthermore, the second sealing plate 93 is located directly above the cylinder 41, and the two opening and closing plates 94 are in a separated state. The anchor rod 5, which was originally supported by the two opening and closing plates 94, falls directly into the cylinder 41, realizing the replenishment operation of the anchor rod 5 into the cylinder 41.

[0081] After the anchor bolts 5 are replenished inside the cylinder 41, the anchor bolt detection component 416 on the upper part of the cylinder 41 detects the anchor bolts 5, indicating that the cylinder 41 does not need to continue replenishing the anchor bolts 5. At this time, the control module 7 controls the material replenishment telescopic rod 91 to shorten from its longest state to its shortest state. During the shortening process of the material replenishment telescopic rod 91, the material replenishment telescopic rod 91 pulls the first sealing plate 92 and the second sealing plate 93 to move and reset in opposite directions, so that the second sealing plate 93 gradually resets to the bottom of the hopper 10, and the two opening and closing plates 94 gradually fit together under the guidance of the guide rail 95.

[0082] When the replenishment telescopic rod 91 is in its shortest state, the second sealing plate 93 is located at the bottom of the hopper 10, the two opening and closing plates 94 are in a spliced ​​state, and the rod part of one of the anchor rods 5 in the hopper 10 is inserted into the first through hole 931 and the second through hole from top to bottom. The head of this anchor rod 5 rests on the top surface of the opening and closing plate 94, ready for replenishment operation.

[0083] Based on the working principle of the replenishing component 9 described above, the advantages of the replenishing component 9 are as follows: The feeding component 9 provided in this embodiment 3 only requires one power source, the feeding telescopic rod 91, to realize the translation and release action of the anchor rod 5. It has a compact and reliable structure and is conducive to saving energy.

[0084] Example 4: This embodiment 4 is an improvement upon embodiment 3: See Figure 14 and Figure 19 A mounting base 102 is fixedly installed on the side of the hopper 10. A slide rod 103 is vertically slidably connected inside the mounting base 102. The top of the slide rod 103 is bent inward to form a clearing rod 1031, and the bottom of the slide rod 103 is bent to form a contact rod 1032. The contact rod 1032 slides with the teeth of the rack 423. An elastic element 104 is provided on the mounting base 102. The elastic element 104 is a spring sleeved on the slide rod 103. The bottom of the spring abuts against the top surface of the mounting base 102, and the top of the spring abuts against the transition section between the clearing rod 1031 and the slide rod 103. The elastic element 104 is used to push the slide rod 103 upward so that the contact rod 1032 keeps in contact with the teeth of the rack 423.

[0085] The working principle of Example 4 is as follows: When the moving cylinder 4 moves along the extension direction of the support frame 3, the moving cylinder 4 drives the hopper 10 to move together through the connecting frame 101. The hopper 10 drives the mounting base 102 and the sliding rod 103 to move together. During the movement of the sliding rod 103, the contact rod 1032 at the bottom of the sliding rod 103 slides and engages with the teeth of the rack 423. Since the sliding rod 103 is also pushed upward by the elastic element 104, the contact rod 1032 moves up and down to adapt to the undulation of the teeth of the rack 423. The contact rod 1032 drives the sliding rod 103 and the unblocking rod 1031 to move up and down together. When the unblocking rod 1031 moves up and down, it continuously strikes the inner wall of the hopper 10. By utilizing the vibration of the inner wall of the hopper 10 and the up and down movement of the unblocking rod 1031, the anchor rods 5 inside the hopper 10 can be loosened, reducing the probability of the anchor rods 5 inside the hopper 10 getting stuck together, so as to ensure the reliability of feeding.

[0086] Based on the working principle described above in Embodiment 4, it can be seen that Embodiment 4 has the following effects: By setting up the mounting base 102, slide bar 103, unblocking rod 1031, contact rod 1032, and elastic element 104, the tooth undulation characteristics of the rack 423 and the elastic force of the elastic element 104 can be used to drive the slide bar 103 to slide up and down in the mounting base 102. This allows the slide bar 103 to drive the unblocking rod 1031 to continuously strike the inner wall of the hopper 10. By using the vibration of the inner wall of the hopper 10 and the up and down movement of the unblocking rod 1031, the anchor rods 5 in the hopper 10 can be unblocked, reducing the probability of the anchor rods 5 in the hopper 10 getting stuck together, so as to ensure the reliability of feeding.

[0087] Furthermore, the unblocking structure formed by the mounting base 102, slide bar 103, unblocking rod 1031, contact rod 1032 and elastic element 104 utilizes the tooth undulation characteristics of the rack 423 and the elastic force of the elastic element 104, so no additional power source is required, which is conducive to saving energy and reducing costs.

[0088] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
