Description

Technical Field

[0001] This invention relates to firebreak creation technology, belonging to the field of forest fire prevention technology, specifically to a forest firebreak creation mechanism, creation equipment, and its usage method. Background Technology

[0002] Frequent forest fires pose a huge threat to forest resources, and once they spread out of control, they often cause devastating consequences. In the forest fire prevention system, the construction of firebreaks can effectively curb the spread of fire and is an important means of the forest fire prevention system. Firebreaks are formed by clearing surface combustibles in key areas to create a fire-free barrier, thereby blocking the spread of forest fires. The main methods for creating firebreaks include manual creation, mechanical creation, and planned burning. Manual creation relies on tools such as chainsaws and brush cutters, which suffers from low efficiency, high labor intensity, and inability to meet urgent needs. Planned burning is greatly affected by weather conditions and is prone to fire accidents. In contrast, mechanical creation has significant advantages such as high work efficiency and good safety. Currently, mechanical conveyor belt cutters use excavators as mobile carriers, with the conveyor belt cutting mechanism installed as an attachment via the excavator's robotic arm. However, the following problems still exist: 1. Existing isolation belt opening mechanisms mainly use rotating components to cut and create channels in the ground to form isolation belts. However, forest environments are complex and inevitably contain vegetation of a certain height. Single-rotation cutting cannot directly act on the cutting position under the vegetation, resulting in incomplete isolation belt opening operations. Utility model patent with publication number CN221332533U: Isolation belt opening device, its disclosure content: the rotation of the digging roller opens channels in the ground to form isolation belts, while the crushing blade rod rotates continuously to crush flammable weeds and trees. In this solution, although it can cut vegetation of a certain height, the cut vegetation can easily tilt directly backward and accumulate behind the equipment or touch high-temperature components, posing a risk of reignition or equipment damage. 2. For larger vegetation, the resistance of the cutting mechanism increases significantly, which can easily lead to entanglement and jamming. For example, if large vegetation is directly inserted into the rotating part, it is difficult to break it into debris quickly during the cutting operation. Therefore, additional cleaning tools are required for processing. Multiple tools need to be used in combination, which results in low efficiency, poor mobility, and difficulty in continuous operation. It is not suitable for forest operation environment. 3. The operation mode of the firebreak opener is relatively simple and its applicability in complex forest environments is poor. For example, when it is necessary to quickly open firebreaks, the equipment needs to push down the vegetation in front of it. For example, during deep tillage, the firebreak opener needs to be inserted into the ground and move forward to bury the ground humus and cutting debris to enhance the firebreak effect. However, the current firebreak opener is installed on a mobile carrier by a robotic arm and is mostly simple horizontal propulsion and pitch angle adjustment, which cannot be applied to complex operation scenarios. Summary of the Invention

[0012] The purpose of this invention is to provide a forest fire prevention barrier device. By connecting components, the forest fire prevention barrier mechanism is installed on a mobile carrier, which can adjust the height and angle of the forest fire prevention barrier mechanism, making the operation more flexible.

[0013] A forest firebreak clearing device includes a forest firebreak clearing mechanism, and further includes: Mobile carrier; The connecting component connects the forest fire prevention opening mechanism and the mobile carrier, and has a second, third and fourth driving component for driving extension and retraction.

[0014] The purpose of this invention is to provide a method for using a forest fire prevention clearing device. It is flexible and reliable in operation and can complete multiple tasks such as site clearing, bumping and clearing, normal clearing, and deep tilling. It is more functional and suitable for complex forest fire prevention clearing environments.

[0015] A method for using a forest fire prevention strip opening device includes the following steps: S1, the mobile carrier drives the forest fire prevention opening mechanism to move, and the connecting parts adjust the height and tilt angle of the forest fire prevention opening mechanism; S2, the upward rotation angle of the pusher component 60° 110°, normal cutting operation is carried out; the crossbeam and shovel teeth at the front of the pusher are lower than the height of the tree being worked on. The pusher acts on the upper part of the tree in front, causing the shovel teeth to press the tree forward and tilt it. Then the cutting part acts on the lower part of the tree to carry out the cutting operation. S3, the upward rotation angle of the pusher component 10° <60°, to carry out the impact-clearing operation; the pusher can directly act on the lower part of the trees in front to carry out a pusher operation with greater force and complete the impact-clearing operation quickly. S4, the upward rotation angle of the pusher component 0° At 10°, site cleaning operations are carried out; the shovel teeth of the pusher component can be close to the ground. During the cleaning process, the adjacent grid plates can screen and filter large materials, while small materials pass through the grid plates and enter the cutting component for cutting operations. With the guide plate parallel to the grid plate as the 0° reference, the guide plate can be driven to rotate 0°-90° to both sides respectively, thereby adjusting the effective width or direction of the material passage between adjacent grid plates and regulating the material flow direction and throughput; when the guide plate is driven to rotate to 90°, the guide plate closes the rear side of the adjacent grid plate, so that the rear side of the pusher component is in a closed state, and the pusher component forms a bucket structure that can hold the material, pushes and collects the material, and pushes the material to the side by turning the moving carrier; S5, during deep plowing operations, the connecting component causes the forest fire prevention opening mechanism to tilt, so that the lower end of the pusher component is lower than the lower horizontal section of the cutting cylinder. The front crossbeam and shovel teeth of the pusher component can be inserted below the ground. The moving carrier drives the forest fire prevention opening mechanism to move forward and carry out deep plowing operations on the ground material.

[0016] Compared with existing technologies, a forest firebreak opening mechanism has the following advantages: 1. The pusher and cutting components are integrated and installed on the support frame, enabling continuous pushing and cutting of materials in the forest. It can screen larger materials, is highly mobile, and is suitable for clearing forest fire shovels. During normal clearing operations, the pusher can act on the upper part of the vegetation, solving the problem that the rotary cutting cannot directly act on the lower part of the vegetation, resulting in incomplete clearing operations. It also prevents vegetation from falling backward toward the equipment, reducing safety hazards. 2. The pusher component is driven to rotate upward by the first drive component, so that the tape-opening mechanism can switch between site cleaning operation, push-and-open tape operation, and normal tape-opening operation. It can correspondingly complete the cleaning of materials close to the ground, push down trees quickly, and open tape at the maximum angle to prevent vegetation from tilting backward, realizing the multi-functionality of tape-opening operation, improving tape-opening efficiency, and is suitable for complex forest operation environment. 3. Driven by the guide plate located behind the grating, the effective width or direction of the material passage between adjacent gratings can be adjusted, the material flow direction and throughput can be regulated, and larger materials can be processed in a concentrated manner. When the guide plate rotates to 90°, it can close the rear side of the pusher component, allowing the pusher component to perform independent shoveling operations, thus making it more widely applicable. 4. By equipping the pusher component with a clearing blade and a clearing plate, when the pusher component is at 0°, the clearing blade can cut the entangled vegetation on the rotating shaft near the end of the cutting cylinder, and the clearing plate can clean the adsorbed soil on the surface near the cutting cylinder, thus solving the problem of vegetation entanglement during cutting operations and improving cutting efficiency. 5. When the site is being cleared, the pusher component is obstructed when pushing the material forward and then lifts slightly upward. This action is transmitted to the first adjusting component via the support rod, which causes the first adjusting component and the second adjusting component to work together. This linkage allows the cutting component to adjust its height according to the obstruction of the pusher component, so that the cutting cylinder can follow the terrain slightly and conform to the shape, thus making it suitable for different terrain environments in the forest. Compared with existing technologies, a forest fire prevention strip opening device has the following advantages: By installing the forest firebreak clearing mechanism on a mobile carrier using connecting components, the height and angle of the mechanism can be adjusted, making operation more flexible. This allows the front of the pusher component to penetrate deep into the ground, deeply turning over and burying humus and cutting debris, thus completing the deep turning operation. Furthermore, the cutting component can clear the surface to a certain depth, cutting and clearing accumulated vegetation or tree roots / stumps in the forest, reducing flammable materials on the ground.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the described embodiments of this invention without creative effort are within the scope of protection of this invention.

[0019] like Figure 1 , Figure 2 , Figure 4 As shown, a forest fire prevention barrier mechanism 100 includes: Support frame 10; The pusher component 20 is located on the front side of the support frame 10 and has a pair of side plates 22, a plurality of grid plates 21 arranged side by side and spaced between the pair of side plates 22, a crossbeam 231 fixedly connected to the lower front end of the grid plate 21, and shovel teeth 232 mounted on the crossbeam 231. The front sides of the crossbeam 231 and the shovel teeth 232 are arc-shaped, and a material passage is formed between adjacent grid plates 21; The cutting component 30 is located on the rear side of the support frame 10 and has a cutting cylinder 31 that is driven to rotate. With the lowest edge of the pusher component 20 aligning with the horizontal cross-section of the lower end of the cutting cylinder 31 as a reference, the pusher component 20 is driven to rotate upwards by the first drive member 24, with a rotation angle of... The process is divided into three sections, and the site cleaning, the impact-driven conveyor belt operation, and the normal conveyor belt operation are completed accordingly. Specifically, the support frame 10 is an integral welded structure, consisting of an upper top plate and two side fixing plates; In the pusher assembly 20, the side plate 22, the grating plate 21, and the crossbeam 231 are welded to form a bucket structure with a volume on the front side. The shovel teeth 232 are made of ultra-high strength material and can directly act on hard objects such as vegetation and gravel. The shovel teeth 232 can be installed and removed from the crossbeam 231 by bolts, fixing seats, etc. The first drive component 24 is a hydraulic cylinder, which is rotatably mounted on the support frame 10 through a support seat. The rotation point, the rotation point where the output end of the first drive component 24 is connected to the pusher assembly 20, and the rotation point where the pusher assembly 20 is installed on the support frame 10 form a triangle to ensure that the first drive component 24 can drive the pusher assembly 20 to rotate after it is started. The crossbeam 231 and the shovel teeth 232 are inclined forward in an arc shape. This design allows the material to roll forward along the arc when pushed, making pushing easier and allowing more material to accumulate in front. There is a certain distance between adjacent grid plates 21 and adjacent shovel teeth 232. Some material will enter the rear from the material passage. The grid plates 21 can perform simple sorting of the material, retaining larger pieces that need to be cleaned for centralized processing. In actual use, the following requirements must be met: > > ,in, The spacing between adjacent shovel teeth 232 For the diameter of the trees being worked on, The distance from the tip of the front end of the shovel tooth 232 to the crossbeam 231 is the distance between the front end of the shovel tooth 232 and the crossbeam 231. This arrangement not only prevents the tree from getting stuck between adjacent shovel teeth 232 when the pusher component 20 is applied to the tree, but also makes it easier to push the tree down because the tree is restricted between adjacent shovel teeth 232. Moreover, due to the depth limitation of the shovel teeth 232, it is not easy to get stuck, making it easier for the shovel teeth 232 to detach from the tree. In the cutting component 30, the cutting cylinder 31 is provided with multiple cutting teeth 32, and the end support shaft is connected to the support frame 10. One of the support shafts extends out and is connected to the hydraulic motor to complete the rotation cutting action of the cutting cylinder 31. When the lowest edge of the pusher component 20 coincides with the horizontal tangential plane of the lower end of the cutting cylinder 31, the pusher component 20 is at the 0° position and rotates upward from this position. As an example, the rotation angle is... The range can be 0°-110°, and it is divided into three intervals: 0°-10°, 10°-60°, and 60°-110°. Within these three intervals, the belt opening mechanism 100 performs site cleaning, belt opening with impact, and normal belt opening operations respectively. The belt-opening mechanism 100 can be installed on the mobile carrier 200. During normal belt-opening operation, the pusher component 20 rotates upward by an angle. 60° 110°, ensuring that the crossbeam 231 and shovel teeth 232 at the front of the pusher component 20 are lower than the height of the tree being worked on. The pusher component 20 acts on the upper part of the tree in front, causing the shovel teeth 232 to press the tree forward at a certain angle to prevent the tree from falling backward and damaging the main unit. Then the cutting component 30 acts on the lower part of the tree to perform the cutting operation. When the pusher is engaged in the opening operation, the pusher component 20 rotates upwards by an angle. 10° <60°, the on-site operator can make fine adjustments within the range according to the on-site conditions. The pusher component 20 can directly act on the lower part of the tree in front to carry out a pusher operation with greater force and complete the rapid opening and impact operation. During site clearing operations, the pusher component 20 rotates upwards at an angle. 0° At 10°, the shovel teeth 232 of the pusher component 20 can be close to the ground and move forward to clean up the ground material; during the cleaning process, the adjacent grid plate 21 can screen and filter materials with larger volume or length, that is, larger materials are blocked in front of the grid plate 21, and the materials will continue to accumulate as the crossbeam 231 and shovel teeth 232 roll forward. During the flipping process, smaller materials can pass through the grid plate 21 and enter the cutting component 30 for cutting operations. When the material in front of the pusher component 20 accumulates to a certain extent, the material can be pushed to the side in a unified manner. In this example, the pusher component 20 and the cutting component 30 are integrated and installed on the support frame 10 to realize the corresponding operations of pushing and cutting materials. It has high mobility and can complete continuous operation. The pusher component 20 can be driven to rotate. On the one hand, it can push the material in front to facilitate the cutting operation and prevent the material from tilting backward after cutting, thus completing the clearing operation of vegetation in the forest. On the other hand, it can realize multiple operations such as normal clearing, bumping clearing, and site clearing. It is suitable for complex forest environments and improves clearing efficiency.

[0020] In some examples of the present invention, such as Figures 6 to 8 As shown, the pusher component 20 also has: a plurality of guide plates 26 correspondingly located on the rear side of the grid plate 21; The front end of each guide plate 26 is driven to rotate, causing its rear end to rotate around the vertical axis to both sides. With the guide plate 26 parallel to the grid plate 21 as the 0° reference, the rotation angle of the guide plate 26 is 0°-90° to both sides. When it rotates to 90°, the guide plate 26 closes the adjacent grid plate 21.

[0021] Furthermore, such as Figure 8 As shown, a worm gear 253 is installed on the upper part of the rotating shaft of the guide plate 26; The drive shaft 251, which is driven to rotate, is installed between a pair of side plates 22. The drive shaft 251 is provided with a plurality of helical teeth 252 that mesh with the worm gear 253. Specifically, the guide plate 26 is hinged to the rear side of the grid plate 21. For example, the upper front end of the guide plate 26 is provided with a rotating shaft, and the upper rear end of the grid plate 21 is provided with a seat plate. The rotating shaft is rotatably mounted in the seat plate through a bearing. A worm gear 253 is installed on the upper part of the rotating shaft. The transmission shaft 251 is rotatably mounted on the side plate 22, and one end is connected to the hydraulic motor through a reducer for driving. The helical teeth 252 on the transmission shaft 251 mesh with the worm gear 253 on the guide plate 26. Preferably, a protective cover can be provided on the outside of the transmission shaft 251, the helical teeth 252, and the worm gear 253. When the hydraulic motor is started, the transmission shaft 251 is driven to rotate through the reducer. The helical teeth 252 at different positions mesh with the worm gear 253 to realize the synchronous rotation of multiple guide plates 26. With the parallel position as the 0° reference, the rotation range is -90° to 90°. Initially, the guide plate 26 is parallel to the grid plate 21, i.e., the angle between them is 0°, which can reduce the impact of materials on the guide plate 26 during normal feeding. When the guide plate 26 is driven to rotate a certain angle, such as 30°, the guide plate 26 adjusts the effective width or direction of the material passage between adjacent grid plates 21, and adjusts the material flow direction and throughput. When the site is being cleaned, some smaller materials can be let through, and larger materials can be concentrated for further cutting and crushing, improving work efficiency. In addition, the guide plate 26 can be driven to swing back and forth to change the direction or guide the material, so that the material is cut more evenly and solves the problem of excessive cutting force in a certain place. When the guide plate 26 is driven to rotate to 90°, that is, when the guide plate 26 is perpendicular to the grid plate 21, the guide plate 26 can close the rear side of the adjacent grid plate 21, so that the rear side of the pusher component 20 is in a near-closed state. The pusher component 20 forms a bucket structure that can hold materials, and completes the pusher collection of materials such as branches and decaying leaves on the forest ground. At this time, the cutting component 30 can be controlled to close. In this example, the guide plate 26 located behind the grating plate 21 is driven to rotate, which can not only adjust the effective width or direction of the material passage between adjacent grating plates 21, and adjust the material flow direction and throughput, so that larger materials can be centrally cut, but also achieve a closed state on the rear side of the pusher component 20, so that the pusher component 20 can independently perform material shoveling operations, and has a wider range of applications.

[0022] In some examples of the present invention, such as Figure 5 As shown, the side plate 22 is provided with a cleaning blade 281, and the upper end of the grid plate 21 is provided with a cleaning plate 282 with elastic properties; The cleaning blade 281 is located between the end side of the cutting cylinder 31 and the side plate of the support frame 10; Among them, when the rotation angle of the pusher component 20 When the angle is 0°, the cleaning blade 281 can approach the rotating shaft at the end of the cutting cylinder 31, and the cleaning plate 282 can approach the circumferential surface of the cutting cylinder 31. Specifically, the rotating shaft on the end side of the cutting cylinder 31 is mounted on the side plate 22 and driven to rotate. In actual assembly, there is a certain gap between the end side of the cutting cylinder 31 and the side plate 22. During cutting operations, this gap can cause vines and other vegetation to become entangled or branches to get stuck, thus affecting cutting efficiency. In addition, since the forest environment is relatively humid, the cutting cylinder 31 can easily absorb some soil on its periphery when it is in operation. The cleaning blade 281 is mounted on the side plate 22 and can rotate with the pusher component 20; When it is necessary to quickly clean most of the dirt and other adhering materials on the cutting cylinder 31 during operation, the pusher component 20 rotates upward at a certain angle, the cutting cylinder 31 is lifted away from the ground, and is driven to gradually increase to the limit speed. The short-term limit speed will shake off most of the dirt on the cutting cylinder 31, and it can quickly enter the working state. When the cutting cylinder 31 is in normal operation and the gap between the end of the cutting cylinder 31 and the side plate 22 is covered with vines or other vegetation, the rotation angle of the pusher component 20 will be adjusted accordingly. At 0°, the clearing blade 281 can cut the vegetation near the rotating shaft at the end of the cutting cylinder 31, that is, at the gap. Then, the cutting cylinder 31 is rotated at a low speed, and the vegetation stuck on the support shaft can be untangled by reversing the rotation. The cleaning plate 282 is made of elastic and wear-resistant material, such as polyurethane. When the rotation angle of the pusher component 20 is 0°, the cleaning plate 282 can approach the surface of the cutting cylinder 31 without affecting the rotation and cutting of the cutting cylinder 31, and remove some highly adsorbent dirt. In this example, by providing a clearing blade 281 and a clearing plate 282 on the pusher component 20, when the pusher component 20 is at 0°, the clearing blade 281 can cut the entangled vegetation on the rotating shaft near the end of the cutting cylinder 31, and the clearing plate 282 can clean the adsorbed soil on the surface near the cutting cylinder 31, thus solving the problem of vegetation entanglement in the cutting operation and improving cutting efficiency.

[0023] In some examples of the present invention, such as Figure 2 , Figure 3 As shown, the support frame 10 is provided with an arc-shaped baffle 41; The baffle 41 is equipped with multiple breaking teeth 42 and a protective chain 43; The breaking teeth 42 are installed at the arc-shaped structure of the baffle 41 and close to the circumferential surface of the cutting cylinder 31. The arrangement direction is consistent with the cutting direction of the cutting cylinder 31. The protective chain 43 is located on the rear side of the cutting cylinder 31. Specifically, the arc-shaped structure of the baffle 41 is consistent with the movement trajectory of the cutting cylinder 31, which is intended to make the crushing tooth 42 fit more closely to the circumferential surface of the cutting cylinder 31. When the cutting cylinder 31 performs cutting operations on the material, the crushing teeth 42 can cooperate with the cutting cylinder 31 to assist in crushing the incoming material, thereby improving the cutting and crushing effect. The protective chain 43 is a flexible connection. When the material flies backward during the cutting process, the protective chain 43 will stop the material and prevent it from flying into the cab, effectively reducing the risk of splashing caused by material cutting.

[0024] In some examples of the present invention, the forest fire prevention opener mechanism also includes a sensing component; The first driving component 24 is rotatably mounted on the support frame 10 via a support base; The sensing component includes a load sensor and an angle sensor; the load sensor is mounted on the support base and is used to identify the force of the load on the pusher component 20; the angle sensor is mounted on the rotation shaft at the end of the pusher component 20 and is used to identify the rotation angle of the pusher component 20. The sensing component is connected to the control component, and the control component controls the movement of the pusher component 20 and the cutting component 30. Specifically, when the pusher component 20 is driven to rotate, the angle sensor acquires the rotation angle in real time, so that the operator can quickly obtain the rotation status of the pusher component 20 and determine the working mode. For example, when the belt is being opened normally, the pusher component 20 rotates upward by 60°-110°, and the operator can make further adjustments within this range based on the acquired angle information. The load sensor acquires the load force on the pusher component 20. For example, when performing a push-and-open operation, the pusher component 20 moves forward and pushes down the trees in front. The load sensor monitors the load value in real time. When there are too many trees or trees with too large a diameter in front, causing the load value to exceed the set threshold, the load sensor provides feedback, and the control component controls the pusher component 20 and the cutting component 30 to stop their actions. It can even control the pusher component 20 to stop moving forward, and the operator can switch to the normal opening operation mode. In this example, by setting up a sensing component, the rotation angle and load condition of the pusher component 20 can be fed back in a timely manner. This allows operators to easily switch and adjust the working mode according to the actual working conditions, avoiding damage to the corresponding components caused by inappropriate angles or excessive loads.

[0025] In some examples of the present invention, such as Figure 9 As shown, the bottom end of the pusher component 20 has a forward tilting structure, which allows the pusher component 20 to contact hard objects and passively withstand the upward rotational force during site clearing operations. One end of the first driving member 24 is connected to the first adjusting member 271 for elastic buffering. A support rod 273 is movably installed inside the first adjusting member 271. The support rod 273 is hinged to the pusher component 20. The rotating shaft on the end side of the cutting cylinder 31 is installed on the slide plate 274. The slide plate 274 is connected to the second adjusting member 272 and can be driven to move up and down on the support frame 10. During site cleaning operations, under the action of the first adjusting member 271 and the second adjusting member 272, when the support rod 273 extends and retracts relative to the first adjusting member 271, the sliding plate 274 moves upward and downward accordingly. Specifically, this example applies to the site cleaning operation of the belt opening mechanism 100, that is, the pusher component 20 performs screening and pushing of materials, the cutting component performs cutting operations, and when the pusher component 20 is obstructed in pushing materials, it is linked with the cutting component 30. This working mode can be determined by the overall posture of the belt opening mechanism 100 and the rotation angle of the pusher component 20 identified by the angle sensor. The lower end of the side plate 22 of the pusher component 20 may be provided with a detachably connected sliding shoe 33. The lower end of the sliding shoe 33 or the shovel tooth 232 is a forward tilting structure. This structure can be arc-shaped or wedge-shaped. The angle between the forward tilting angle and the horizontal plane can be 5°-10°. The purpose is that when the pusher component 20 encounters a large obstacle resistance during forward movement, it can withstand the upward rotational force. That is, when the shovel tooth 232 is resisted in its forward movement, an upward torque component is generated due to the forward tilting angle, which causes the pusher component 20 to have a tendency to "lift up" and avoids the shovel tooth 232 from sticking to the ground and being unable to lift up. The slide plate 274 can be connected to the side plate 22 via a linear guide rail, and the hydraulic motor that drives the cutting cylinder 31 to rotate is mounted on the slide plate 274; When the site is being cleared, the pusher component 20 is obstructed when pushing material forward and then slightly lifts upward. This action is transmitted through the support rod 273 to the first adjusting component 271, causing the first adjusting component 271 and the second adjusting component 272 to move in tandem. That is, when the support rod 273 retracts, the second adjusting component 272 drives the sliding plate 274 to move downward, and when the support rod 273 extends, the second adjusting component 272 drives the sliding plate 274 to move upward. This linkage allows the cutting component 30 to adjust its height according to the obstruction of the pusher component 20, and the cutting cylinder 31 to follow the terrain with slight movement, thus making it suitable for different terrain environments in the forest. As a first example of the first adjusting member 271 and the second adjusting member 272, the first adjusting member 271 is a cylinder and a first spring is provided inside the cylinder. One end of the support rod 273 is slidably located inside the cylinder and is subjected to a forward elastic force. A pressure sensor is provided inside the cylinder to identify the force on the support rod 273. The second adjusting member 272 can be a hydraulic cylinder. The pressure sensor is connected to a control component, and the control component controls the extension and retraction of the hydraulic cylinder. During site clearing operations, the pusher component 20 moves forward and encounters a protruding obstacle, causing it to be obstructed and lifted (rotate upwards). The support rod 273 compresses the first spring. When the pressure sensor detects a pressure change exceeding a set threshold, the control unit controls the hydraulic cylinder to extend, causing the slide plate 274 to move downwards by a small amount. This small amount allows the cutting cylinder 31 to act on the protruding obstacle, completing the cutting operation. After avoiding the obstacle and when the pressure is below the set threshold, the support rod 273 returns to its initial position under the action of the first spring and the gravity of the pusher component 20. The control unit then controls the hydraulic cylinder... The retraction causes the slide plate 274 to move upward to its initial position. Therefore, the movement of the support rod 273 and the slide plate enables the linkage between the pusher component 20 and the cutting component 30, allowing the cutting cylinder 31 to follow the terrain with slight contouring. Note that because there is a certain distance between the pusher component 20 and the cutting component 30, when the pusher component 20 is raised, the control component can appropriately delay the movement to allow the cutting component 30 to better act on the obstacle. When the operation is not in a designated area, the control component does not control the movement of the second adjusting component 272. In this case, when the pusher component 20 encounters resistance while pushing material, it cannot link with the cutting component 30. As a second example of the first adjusting member 271 and the second adjusting member 272, such as Figure 9 , Figure 10 As shown, the first adjusting member 271 has a first cylinder and a first spring located in the cavity of the first cylinder; one end of the support rod 273 is a piston structure that divides the first cylinder into a front cavity and a rear cavity, and the support rod 273 bears the forward elastic force of the first spring. The rotating shaft at the end of the cutting cylinder 31 is mounted on the slide plate 274. The slide plate 274 is movably mounted on the support frame 10 and connected to the second adjusting member 272. The second adjusting member 272 has a second cylinder, a piston rod with one end fixed on the slide plate 274, and a second spring located in the lower cavity of the second cylinder. The other end of the piston rod slides in the second cylinder to divide it into an upper cavity and a lower cavity. The piston rod bears the upward elastic force of the second spring. The rear cavity of the first cylinder and the upper cavity of the second cylinder are connected through the first pipe 275 and filled with oil, and the front cavity of the first cylinder and the lower cavity of the second cylinder are connected through the second pipe 276 and filled with oil; an accumulator 277 is provided on the first pipe 275 and the second pipe 276, and the control component controls the operation of the accumulator 277. Specifically, for ease of description, the front and rear chambers of the first cylinder are defined as chamber a and A, respectively, and the first spring is located in chamber A; the upper and lower chambers of the second cylinder are defined as chambers B and b, respectively, and the second spring is located in chamber b. Initially, under the action of the first spring and the second spring, the piston rod drives the slide plate 274 to be in the upper position and the support rod 273 to be in the extended state. At this time, the cavity a and the cavity b are connected and the cavity A and the cavity B are connected and in a balanced state. During site clearing operations, the pusher component 20 moves forward and encounters a protruding obstacle, causing it to be obstructed and lifted (rotating upwards). The support rod 273 squeezes the cavity A and simultaneously compresses the first spring. Oil flows from cavity A and the first pipe 275 into cavity B, increasing the volume inside cavity B and causing the piston rod to move downwards, compressing the second spring. The sliding plate 274 moves downwards, allowing the cutting cylinder 31 to act on the protruding obstacle. At the same time, oil flows from cavity b and the second pipe 276 into cavity a, achieving a state of equilibrium. After avoiding the obstacle, under the action of the first and second springs, the piston rod drives the slide plate 274 to move upward and return to the initial position. The volume of cavity B decreases, and oil enters cavity A from cavity B and the first pipe 275. At the same time, oil enters cavity b from cavity a and the second pipe 276, and the two are in a balanced state. Accumulators 277 are connected to the first pipe 275 and the second pipe 276. Accumulators 277 can compensate for the oil flow and prevent the piston rod from responding too slowly when the support rod 273 moves. When the site is not being cleaned, the control unit controls the accumulator 277 not to perform oil compensation. For example, the accumulator 277 is equipped with a valve group that is controlled to open and close by the control unit. When the site is being cleaned, the valve group is in the open state, and the accumulator 277 can perform normal oil compensation. When the site is not being cleaned, the valve group is in the closed state. At this time, when the pusher component 20 is obstructed, it cannot be linked with the cutting component 30.

[0026] A forest fire prevention strip opening device, such as Figure 11 As shown, the forest fire prevention and control mechanism described above also includes: Mobile carrier 200; The connecting component is connected between the belt opening mechanism 100 and the moving carrier 200, and has a second driving member 210, a third driving member 220 and a fourth driving member 230 arranged sequentially from top to bottom. The second drive unit 210 is hinged at one end to the mobile carrier 200 and at the other end to the upper part of the support frame 10. The fourth drive component 230 is hinged at one end to the mobile carrier 200 and at the other end to the lower part of the support frame 10. The third drive unit 220 is hinged at one end to the moving carrier 200 and at the other end to the ear seat 240 on the fourth drive unit 230; The control unit is connected to the connecting unit and controls the second drive unit 210, the third drive unit 220 and the fourth drive unit 230 to operate sequentially. Specifically, the mobile carrier 200 can be a loader, excavator, or other vehicle suitable for forest clearing operations; The connecting component is configured to adjust the height and tilt direction of the belt opening mechanism 100. The second drive member 210, the third drive member 220, and the fourth drive member 230 can all be hydraulic cylinders connected to the control component. The control component adjusts the actions of the second drive member 210, the third drive member 220, and the fourth drive member 230 according to the working state. This action is the extension and retraction of each cylinder. It should be noted that the control component coordinating with the corresponding drive members is a conventional structure. A fixing plate can be welded to the rear side of the support frame 10, and pins are installed on both the fixing plate and the ear seat 240; one end of the second drive member 210, the third drive member 220 and the fourth drive member 230 can be hinged to the mobile carrier 200 through the fixing seat, and the telescopic end can be connected to the corresponding position through the pin. For example, the telescopic end of the second drive member 210 is hinged to the upper pin 11, the telescopic end of the fourth drive member 230 is hinged to the lower pin 12, and the telescopic end of the third drive member 220 is hinged to the pin of the ear seat 240. The second drive member 210 controls the belt opening mechanism 100 to perform circular motion with the lower pin 12 as the center. The third drive member 220 enables the fourth drive member 230 to perform circular motion, indirectly controlling the lifting and lowering of the belt opening mechanism 100. The fourth drive member 230 directly controls the lifting and lowering of the belt opening mechanism 100. For example, when the third drive member 220 and the fourth drive member 230 remain unchanged, the second drive member 210 extends or retracts, completing the tilt angle adjustment of the belt opening mechanism 100. This adjustment enables the belt opening mechanism 100 to perform deep turning operations, and the rotation angle of the pusher component 20 is adjusted. When the angle is 0°, the second drive member 210 extends, the belt opening mechanism 100 rotates around the lower pin 12, the front crossbeam 231 and the shovel teeth 232 of the pusher component 20 can be inserted below the ground, the moving carrier 200 drives the belt opening mechanism 100 to move forward, deeply burying the ground humus and cutting debris, and enhancing the function of the fireproof isolation belt.

[0027] The specific steps for using this forest fire prevention opener are as follows: S1, the mobile carrier 200 drives the belt opening mechanism 100 to move, and the connecting component adjusts the height and tilt angle of the belt opening mechanism 100; S2, During normal operation, the pusher component 20 rotates upwards at an angle. 60° At 110°, the crossbeam 231 and shovel teeth 232 at the front of the pusher component 20 are lower than the height of the tree being worked on. The pusher component 20 acts on the upper part of the tree in front, causing the shovel teeth 232 to press the tree forward. Then the cutting component 30 acts on the lower part of the tree to perform the cutting operation. S3, when the pusher assembly 20 rotates upward during the push-off operation. 10° <60°, the pusher component 20 can directly act on the lower part of the tree in front to carry out a pusher operation with greater force and complete the rapid opening and impact operation; S4, When the site is being cleared, the pusher component 20 rotates upwards by an angle. 0° At 10°, the shovel teeth 232 of the pusher component 20 can be close to the ground. During the cleaning process, the adjacent grid plate 21 can screen and filter large materials, while small materials pass through the grid plate 21 and enter the cutting component 30 for cutting operations. With the guide plate 26 parallel to the grid plate 21 as the 0° reference, the guide plate 26 can be driven to rotate 0°-90° to both sides respectively, thereby adjusting the effective width or direction of the material passage between adjacent grid plates 21, and adjusting the material flow direction and throughput; when the guide plate 26 is driven to rotate to 90°, the guide plate 26 closes the rear side of the adjacent grid plate 21, so that the rear side of the pusher component 20 is in a closed state, and the pusher component 20 forms a bucket structure that can hold materials, pushes and collects the materials, and pushes the materials to the side by turning the mobile carrier 200; S5, during deep turning operation, the connecting component drives the opening mechanism 100 to tilt, so that the lower end of the pusher component 20 is lower than the lower horizontal section of the cutting cylinder 31, and the front crossbeam 231 and the shovel teeth 232 of the pusher component 20 can be inserted below the ground. The moving carrier 200 drives the opening mechanism 100 to move forward to perform deep turning operation on the ground material.
