Description

Technical Field

[0001] This invention relates to the field of mine restoration technology, and in particular to a mountain reinforcement device for mine restoration. Background Technology

[0002] After mining is completed, it causes serious damage to the ecological environment of the mountain. In order to achieve sustainable development of the environment, it is necessary to restore the mine ecology.

[0003] However, after mining, the soil's compaction capacity decreases, and conventional planting methods are no longer sufficient for plant growth. Therefore, it is necessary to lay additional covering nets to fix the soil, provide the necessary conditions for plant growth, prevent the seeds from being blown away by the wind, and ensure the germination rate of the seeds.

[0004] Chinese invention patent CN115804280A discloses an integrated intelligent mine restoration and greening machine. The technical solution of this patent involves using tracks as a moving mechanism and employing an automatic spraying mechanism, an anchor bolt changing mechanism, and an automatic anchor bolt installation mechanism to complete the fixing and greening work. However, this patent has a complex structure and low linkage, and its mesh laying technology differs from the mesh laying technology of this application, resulting in different technical effects. Therefore, to address these shortcomings, a mountain reinforcement device for mine restoration has been invented. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by providing a mountain reinforcement device for mine restoration, thus overcoming the problems in the prior art.

[0006] To address the aforementioned technical problems, this invention provides a hillside reinforcement device for mine restoration, comprising a spreading mechanism and a nailing mechanism mounted on the spreading mechanism. The spreading mechanism includes a vehicle body and a track for movement. A covering net laying mechanism and a seed-spreading mechanism are provided on the vehicle body. The covering net laying mechanism includes a drive motor, a conveyor belt, a drive shaft, and a trapezoidal guide frame. The trapezoidal guide frame is positioned in the vehicle body's travel direction, and the conveyor belt is laid on the trapezoidal guide frame, with its transmission direction consistent with the vehicle body's travel direction. The drive motor is mounted on the vehicle body, and its output shaft is connected to the drive shaft. The drive shaft is rotatably mounted on the vehicle body, and a rotating wheel is located in the middle of the drive shaft, with the rotating wheel being connected to the conveyor belt. A limiting frame is provided above the conveyor belt, fixedly connected to the vehicle body, and a covering net is placed within the limiting frame, with the bottom layer of the covering net in contact with the conveyor belt.

[0007] The seed-spreading mechanism includes a seed box and a feeding channel. The seed box is mounted on the vehicle body. The upper inlet of the feeding channel is connected to the seed box, and the lower end extends to the bottom of the vehicle body. A baffle is provided at the lower outlet of the feeding channel. The baffle is slidably connected to the feeding channel. The baffle is connected to the transmission shaft through a transmission mechanism, and the rotation of the transmission shaft drives the baffle to open or close the outlet of the feeding channel.

[0008] The nailing mechanism consists of two sets, symmetrically installed at the rear of the vehicle body. Each nailing mechanism includes an anchor nail conveying mechanism and a nailing frame. The anchor nail conveying mechanism includes a material chute, an anchor nail, a blocking slider, and a nailing spring. The blocking slider is slidably installed on the vehicle body and connected to the vehicle body via the nailing spring. The blocking slider corresponds to the position of the material chute, which is installed on the vehicle body. The nailing frame is rotatably installed on the vehicle body, with a magnet at its free end. The nailing frame cooperates with the blocking slider. Both ends of the drive shaft are connected to the nailing frames of the two sets of nailing mechanisms via transmission components. The drive shaft controls the two sets of nailing frames to rotate forward to attract the anchor nails conveyed by the anchor nail conveying mechanism via magnets, and to rotate in the reverse direction to drive the anchor nails into the laid cover netting, thus fixing the cover netting.

[0009] A further technical solution of the present invention: a water tank is also installed on the vehicle body, and a valve that can be repeatedly opened and closed is installed on the water tank.

[0010] A further technical solution of the present invention: The transmission assembly includes a first nailing gear, a first incomplete gear, a second nailing gear, a third nailing gear, a fourth nailing gear, a second incomplete gear, a long belt, and a short belt. The transmission shaft has symmetrically arranged transmission pulleys matched with the long belts at both ends. The transmission shaft is connected to the gear shaft of the second nailing gear via the long belt, driving the second nailing gear to rotate. The second nailing gear is connected to the first incomplete gear via the short belt, driving the first incomplete gear to rotate. The first incomplete gear cooperates with the first nailing gear, and the first nailing gear cooperates with the second incomplete gear... The gears are fully engaged. The second incomplete gear is coaxially and fixedly connected to the fourth nailing gear. The fourth nailing gear meshes with the third nailing gear, and the third nailing gear meshes with the second nailing gear. Simultaneously, the second nailing gear drives the third nailing gear to rotate, the third nailing gear drives the fourth nailing gear to rotate, and the fourth nailing gear drives the second incomplete gear to rotate. When the first incomplete gear meshes with the first nailing gear, the second incomplete gear disengages from the first nailing gear. When the second incomplete gear meshes with the first nailing gear, the first incomplete gear disengages from the first nailing gear.

[0011] The preferred technical solution of the present invention is as follows: the trapezoidal guide frame is arranged on the central axis of the vehicle body in the direction of travel, the drive shaft is arranged below the conveyor belt and laid perpendicular to the conveying direction of the conveyor belt, the conveyor belt is a drive rack, and the rotating wheel is a drive gear that meshes with the conveyor belt.

[0012] The preferred technical solution of the present invention is as follows: the limiting frame and the top surface of the vehicle body are provided with a spacing that matches the thickness of the covering net, and during the conveyor belt transmission process, the bottom layer of the covering net in the limiting frame moves to the rear of the vehicle along with the conveyor belt.

[0013] The preferred technical solution of the present invention is as follows: the transmission mechanism includes a first spreading gear rotatably mounted on the vehicle body support and a second spreading gear coaxially fixed on the transmission shaft. The second spreading gear meshes with the first spreading gear. The baffle is connected to the first spreading gear through a connecting rod. One end of the connecting rod is rotatably connected to the eccentric position of the first spreading gear, and the other end of the connecting rod is rotatably mounted on the baffle. Under normal conditions, the baffle blocks the outlet of the material discharge channel.

[0014] The preferred technical solution of the present invention is as follows: the material chute is installed on the vehicle body at an incline, and an anchor is placed inside the material chute, with an iron sheet attached to the anchor; the material chute has an anchor discharge bin at its inlet or is connected to an external anchor conveying mechanism.

[0015] The preferred technical solution of the present invention is that the first incomplete gear (208) and the second incomplete gear are half gear structures with the same structure, and the gear is arranged only on half of the outer edge of each gear.

[0016] The preferred technical solution of the present invention is as follows: the first nailing gear is fixedly connected to the nailing frame, a limiting groove is installed on the vehicle body, and the second end of the nailing frame is slidably installed in the limiting groove of the vehicle body.

[0017] The advantages of this invention compared to the prior art are:

[0018] (1) The present invention first places the covering net into the limiting frame of the vehicle body, starts the motor to drive the transmission shaft to rotate, the transmission shaft drives the rotating wheel to rotate, the rotating wheel drives the conveyor belt to move on the trapezoidal guide frame, and the conveyor belt transports the covering net to the rear of the vehicle to realize continuous net laying operation.

[0019] (2) When the transmission shaft rotates in this invention, it drives the rotating wheel to rotate, drives the first spreading gear to rotate, the first spreading gear drives the connecting rod to swing, drives the baffle to move back and forth, opens and closes the outlet of the feeding channel, so that the seeds inside the seed box are intermittently and regularly sprinkled, while the valve of the water tank is repeatedly opened and closed to sprinkle water evenly.

[0020] (3) In this invention, the first nailing gear rotates forward and backward to drive the nailing frame to rotate forward and backward. When the nailing frame rotates forward to the direction of the sliding groove, it presses down the blocking slider, compresses the nailing spring, and releases the restriction on the anchor nail. Then the anchor nail slides into the groove of the nailing frame. The iron plate on the anchor nail is attracted by the magnet to prevent the anchor nail from falling off when the nailing frame rotates. Then the reversed nailing frame drives the anchor nail to rotate and nails the anchor nail into the ground. Attached Figure Description

[0031] The embodiment provides a mountain reinforcement device for mine restoration, such as Figures 1-7 The diagram shows a spreading mechanism 1 and a nailing mechanism 2 mounted on the spreading mechanism 1. The spreading mechanism 1 includes a vehicle body 101 and a track 103 mounted on the vehicle body 101 for movement. A covering net laying mechanism and a seed spreading mechanism are provided on the vehicle body 101. The covering net laying mechanism includes a drive motor, a conveyor belt 102, a drive shaft 104, and a trapezoidal guide frame 113. The trapezoidal guide frame 113 is located on the central axis of the vehicle body 101 in the direction of travel. The conveyor belt 102 is laid on the trapezoidal guide frame 113, and its transmission direction is consistent with the direction of travel of the vehicle body 101. The drive shaft 104 is located below the conveyor belt 102 and is laid perpendicular to the transmission direction of the conveyor belt 102. The drive motor is mounted on the vehicle body 101, and its output shaft is connected to the drive shaft 104. A rotating wheel 105 is provided, and the rotating wheel 105 is connected to the conveyor belt 102 for transmission. The conveyor belt 102 is a transmission rack, and the rotating wheel 105 is a transmission gear that meshes with the conveyor belt 102. A limiting frame is provided on the top of the vehicle body 101, and the limiting frame is located above the conveyor belt 102. There is a gap between the limiting frame and the top surface of the vehicle body 101 that matches the thickness of the covering net 3. The covering net 3 is placed inside the limiting frame. The bottom layer of the covering net 3 inside the limiting frame is in contact with the conveyor belt 102. When the drive motor drives the transmission shaft 104 to rotate, it drives the conveyor belt 102 to perform transmission. During the transmission of the conveyor belt 102, the bottom layer of the covering net 3 inside the limiting frame moves away from the limiting frame through the gap between the limiting frame and the vehicle body 101, moves to the rear of the vehicle, and is laid on the ground after sowing.

[0032] The seed-spreading mechanism includes a seed box 106 and a feeding channel 107. The seed box 106 is mounted on the vehicle body 101. The upper inlet of the feeding channel 107 is connected to the seed box 106, and the lower end extends to the bottom of the vehicle body 101. A baffle 108 is provided at the lower outlet of the feeding channel 107. The baffle 108 is slidably connected to the feeding channel 107. The baffle 108 is connected to the drive shaft 104 through a transmission mechanism. The transmission mechanism includes a first spreading gear 110 rotatably mounted on the vehicle body bracket and a second spreading gear 111 coaxially fixed on the drive shaft 104. The second spreading gear 111 meshes with the first spreading gear 110. The baffle 108 is connected to the first spreading gear 110 through a connecting rod 109. One end of the connecting rod 109 is rotatably connected to the eccentric position of the first spreading gear 110, and the other end of the connecting rod 109 is rotatably mounted on the baffle 108. Under normal conditions, the baffle 108 blocks the outlet of the feeding channel 107.

[0033] When the drive shaft 104 rotates, it drives the second spreading gear 111 to rotate. The second spreading gear 111 drives the first spreading gear 110 to rotate. The first spreading gear 110 drives the connecting rod 109 to swing, thereby causing the baffle 108 to move back and forth, opening and closing the outlet of the feeding channel 107, so that the seeds inside the seed box 106 are intermittently and regularly scattered. At the same time, the valve of the water tank 112 repeatedly opens and closes, evenly sprinkling water. After the seeds are scattered on the soil, as the vehicle body 101 moves, the subsequent covering net 3 will cover the area where the seeds were scattered and be fixed to the ground by the anchor nails 202, so that the seeds can better adhere to the soil, thereby preventing the seeds from being blown away by strong winds and increasing the survival rate of the seeds.

[0034] The vehicle body 101 is also equipped with a water tank 112, which has a valve that can be opened and closed repeatedly.

[0035] The embodiment provides a mountain reinforcement device for mine restoration, such as Figures 1-7As shown, the nailing mechanism 2 has two sets, symmetrically installed at the rear of the vehicle body 101. Each nailing mechanism 2 includes an anchor nail conveying mechanism and an anchor nail fixing mechanism. The anchor nail conveying mechanism includes a sliding chute 201, anchor nails 202, a blocking slider 203, and a nailing spring 204. The blocking slider 203 is slidably installed on the vehicle body 101 and connected to the vehicle body 101 via the nailing spring 204. The blocking slider 203 corresponds to the position of the sliding chute 201, which is installed on the vehicle body 101 and can hold multiple anchor nails 202. The sliding chute 201 is inclined. Under normal conditions, the blocking slider 203 blocks the outlet of the sliding chute 201. A nail storage box can also be installed at the upper feed end of the sliding chute 201, or it can be connected to other external anchor nail conveying mechanisms to facilitate uninterrupted anchor nail delivery. The anchor fixing mechanism includes a nail-driving frame 205 and a magnet 206. One end of the nail-driving frame 205 is rotatably mounted on the vehicle body 101, and the free end is provided with a magnet 206. Both ends of the drive shaft 104 are connected to the nail-driving frames 205 of the two sets of nail-driving mechanisms 2 through a transmission assembly, and the drive shaft controls the rotation of the two sets of nail-driving frames 205 to pick up the anchor nails 202 conveyed by the anchor nail conveying mechanism through the magnet 206, and drive the anchor nails 202 into the newly laid cover net 3 to fix the cover net 3. The nail-driving frame 205 cooperates with the blocking slider 203. An iron plate is provided on the anchor nail 202.

[0036] The transmission assembly includes a first nailing gear 207, a first incomplete gear 208, a second nailing gear 209, a third nailing gear 210, a fourth nailing gear 211, a second incomplete gear 212, a long belt 213, and a short belt 214. The transmission shaft 104 has symmetrically arranged transmission pulleys at both ends matched with the long belt 213, and the long belt 213 drives the transmission shaft 104 to the gear shaft of the second nailing gear 209. The gear shaft of the second nailing gear 209 is connected to the gear shaft of the first incomplete gear 208 via the short belt 214. The first incomplete gear 208 engages with the first nailing gear 207, which in turn engages with the second incomplete gear 212. The second incomplete gear 212 is coaxially and fixedly connected to the fourth nailing gear 211. The fourth nailing gear 211 meshes with the third nailing gear 210, which in turn meshes with the second nailing gear 209. All four gears—the first nailing gear 207, the first incomplete gear 208, the second nailing gear 209, the third nailing gear 210, and the fourth nailing gear 211—are rotatably mounted on the vehicle body 101. The first incomplete gear 208 and the second incomplete gear 212 are identical half-gear structures, with only half of the outer edge of each gear having a gear. The first nailing gear 207 is fixedly connected to the nailing bracket 205, and a limiting groove is installed on the vehicle body 101. The second end of the nailing bracket 205 is slidably mounted in the limiting groove of the vehicle body 101.

[0037] The working process of this invention is as follows: First, multiple covering nets 3 are placed within the limiting frame of the vehicle body 101, and one of the covering nets 3 is placed at the rear of the vehicle. The motor is started to drive the transmission shaft 104 to rotate, and the transmission shaft 104 drives the rotating wheel 105 to rotate. When the transmission shaft 104 rotates, it drives the first spreading gear 110 to rotate. The first spreading gear 110 drives the connecting rod 109 to swing, thereby driving the baffle 108 to move back and forth, opening and closing the outlet of the feeding channel 107, so that the seeds inside the seed box 106 are intermittently and regularly scattered into the soil. At the same time, the valve of the water tank 112 is repeatedly opened and closed to evenly sprinkle water. After the seeds are sown on the soil, as the vehicle body 101 moves, the drive shaft 104 rotates the wheel 105, which drives the conveyor belt 102 to move on the trapezoidal guide frame 113. The conveyor belt 102 transports the covering net 3 towards the rear of the vehicle. During the transport process, the next covering net can push the previous covering net 3 that is at the rear of the vehicle further back, causing it to fall to the ground, thus realizing continuous net laying operation. The laid covering net 3 will then cover the position where the seeds were sown.

[0038] During the netting process, the drive shaft 104 drives the second nailing gear 209 to rotate via the long belt 213. The second nailing gear 209 drives the first incomplete gear 208 to rotate via the short belt 214. Simultaneously, the second nailing gear 209 drives the third nailing gear 210 to rotate, the third nailing gear 210 drives the fourth nailing gear 211 to rotate, and the fourth nailing gear 211 drives the second incomplete gear 212 to rotate. When the first incomplete gear 208 meshes with the first nailing gear 207, the second incomplete gear 212 disengages from the first nailing gear 207. When the second incomplete gear 212 meshes with the first nailing gear 207, the first incomplete gear 208 disengages from the first nailing gear 207, thus realizing the reciprocating forward and reverse rotation of the first nailing gear 207. After the netting work is completed, the nailing mechanism can be used to nail and fix the laid covering net 3, allowing the seeds to better adhere to the soil, thereby preventing the seeds from being blown away by strong winds and increasing the seed survival rate.

[0039] In the nailing decoration of this invention, under normal conditions, the blocking slider 203 blocks the outlet of the material channel 201; the first nailing gear 207 rotates forward and backward, driving the nailing frame 205 to rotate forward and backward. When the nailing frame 205 rotates forward towards the material channel 201, it presses down the blocking slider 203, compresses the nailing spring 204, and releases the restriction on the anchor nail 202. Then the anchor nail 202 slides into the groove of the nailing frame 205; the iron piece on the anchor nail 202 is attracted by the magnet 206 to prevent the anchor nail 202 from falling off when the nailing frame 205 rotates; then the reverse-rotating nailing frame 205 drives the anchor nail 202 to rotate, nailing the anchor nail 202 into the ground, and fixing the covering net 3 to the ground through the anchor nail 202.

[0040] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of the present invention.
