The lower ends of the second springs 29 are respectively fixed to the U-shaped seat 14, and the upper ends of the second springs 29 are respectively fixed to the lock rack 28, so that the lock rack 28 has an upward driving force under normal conditions; the support cylinder 25 is used to support the limited winding shaft 23 and other parts, and the left and right ends of the outer surface of the winding shaft 23 are respectively fixed with crank handles 24, and the function of the crank handle 24 is to facilitate driving the winding shaft 23 to rotate; the left and right ends of the U-shaped seat 14 are respectively provided with long key holes, and the winding shaft 23, the crank handle 24, and the winding shaft 23 can be driven to rotate by the long key holes. The extension pin 40 and the like move up and down on the U-shaped seat 14 following the U-shaped frame 17; after the protective net 3 is unfolded, through the cooperation of the provided lock gear 27 and the lock rack 28, when the lock gear 27 and the lock rack 28 meet and mesh, the rotation of the lock gear 27 and the winding shaft 23 can be restricted, that is, the protective net 3 can be locked, and through the cooperation of the provided second spring 29 and the lock rack 28, the lock rack 28 can have a space range for moving up and down, that is, after the protective net 3 is unfolded, by rotating the first handle 15, the U-shaped frame 17, the winding shaft 23, the protective net 3, etc. can continue to move downward, and the protective net 3 is adjusted to fit on the slope surface, and the winding shaft 2 When the lock gear 27 moves downward, it can also drive the lock gear 27 to move downward. When the lock gear 27 moves downward, it can also drive the lock rack 28 to move downward and compress the second spring 29. When the lock rack 28 moves downward, it can always keep in meshing with the lock gear 27 and will not disengage, thereby limiting the rotation of the lock gear 27 and the winding shaft 23. When in use, the first handle 15 is driven to move the U-shaped frame 17, the winding shaft 23, the protective net 3, etc. downward to a specified position, that is, the corresponding scraper 33 moves backward to the top position and disengages from the protective net 3, and the pressure wheel 19 moves upward to the top position and disengages from the protective net 3. At this time, the lock gear 27 and the lock rack 28 have not yet met and meshed, driving the crank handle 24 or pulling it to one side can unfold the protective net 3. After the protective net 3 is fully unfolded, the first handle 15 is driven again to make the protective net 3 move downward to contact the slope surface, and the lock gear 27 will meet and mesh with the lock rack 28, which will limit the rotation of the lock gear 27 and the winding shaft 23 and the movement of the protective net 3, that is, the protective net 3 is fixed. When the first handle 15 is driven to rotate in the opposite direction, the protective net 3, the lock gear 27, etc. can be driven to move upward. When the lock gear 27 moves upward, it can be disengaged from the lock rack 28. After moving upward to the top, the winding shaft 23 can rotate and the protective net 3 can be folded;The inner wall of the support cylinder 25 is fixedly connected with a coil spring 26, and the other end of the coil spring 26 is fixedly connected to the reel shaft 23. When the protective net 3 is unfolded, the reel shaft 23 is driven to rotate forwardly. When the reel shaft 23 rotates forwardly, the coil spring 26 can be compressed. After being compressed, the coil spring 26 has a reverse rotation force on the reel shaft 23, that is, when the protective net 3 is reeled, it is convenient for the protective net 3 to be retracted onto the outer surface of the reel shaft 23. The coil spring 26 can be set according to the size of the protective net 3. When the protective net 3 is short and narrow, the unfolded protective net 3 is no longer required to be manually operated by the set coil spring 26 when it is reeled. When the protective net 3 is long and wide, the reeling protective net 3 is driven by the crank 24. ;

[0050] The inner end surfaces of the two support cylinders 25 are respectively rotatably connected with inner ratchet wheels 45, and the left and right ends of the outer surface of the winding shaft 23 are respectively fixed with discs 42. The inner end surfaces of the two discs 42 are respectively hinged with ratchet teeth 44 that cooperate with the inner ratchet wheels 45 at non-center positions, and the inner end surfaces of the two discs 42 are also respectively fixed with elastic sheets 43 that cooperate with the ratchet teeth 44.

[0051] like Fig.16 As shown, the elastic sheet 43 always has an outward elastic force on the ratchet 44, so that the ratchet 44 and the inner ratchet 45 can be stably meshed under normal conditions. Through the mutual cooperation of the inner ratchet 45, the disc 42, the ratchet 44 and the elastic sheet 43, the unidirectional transmission rotational force of the winding shaft 23 can reach the inner ratchet 45, that is, when the winding shaft 23 rotates forward and the protective net 3 is opened, the ratchet 44 can follow the winding shaft 23 and the disc 42 to rotate in a circle, and will produce relative sliding with the inner ratchet 45, that is, it will not drive the inner ratchet 45 to rotate. When the winding shaft 23 rotates reversely and the protective net 3 is folded, the ratchet 44 will move in the reverse circle, and in engagement with the inner ratchet 45, the inner ratchet 45 can follow the winding shaft 23 to rotate in the reverse direction synchronously, and when the inner ratchet 45 rotates, it can drive the knocking ball 56 to work normally.

[0052] The inner walls at the left and right ends of the U-shaped frame 17 are respectively slidably connected with the second spur rack 47, and the inner walls at the left and right ends of the U-shaped frame 17 are also respectively fixed with support pads 50, and the front end surfaces of the support pads 50 are respectively fixed with tension springs 49, and the front ends of the tension springs 49 are respectively fixed to the corresponding second spur racks 47, and the outer surfaces of the inner ratchet 45 are respectively fixed with incomplete spur gears 46 that match the second spur rack 47; the upper side of the front end surface of the U-shaped frame 17 is fixed with a limiting shaft 58, and the outer surface of the limiting shaft 58 is respectively rotatably connected with multiple swing rods 55, and the inner walls of the multiple swing rods 55 are fixed with a connecting shaft 57, and the knocking balls 56 are respectively fixed to the lower ends of the corresponding swing rods 55, and the left and right ends of the outer surface of the connecting shaft 57 are respectively rotatably connected with the first connecting rod 48, and the lower ends of the first connecting rod 48 are respectively hinged to the corresponding second spur rack 47.

[0053] like Figure 15-16As shown, the second spur rack 47 can be slidably connected to the inner wall of the U-shaped frame 17 forward and backward, and the support pad 50 supports and fixes the tension spring 49. The tension spring 49 always has a backward pulling force on the second spur rack 47, even if the second spur rack 47 always has a backward driving force; when the winding shaft 23 rotates in the opposite direction to drive the inner ratchet 45 to rotate in the opposite direction, it can drive the incomplete spur gear 46 to rotate. When the toothed part of the incomplete spur gear 46 meets the second spur rack 47, it can drive the second spur rack 47 to move forward. When the second spur rack 47 moves forward, the tension spring 49 can be stretched. When the incomplete spur gear 46 rotates to the toothed part, the second spur rack 47 can be driven to move forward. When the toothed portion meets the second spur rack 47, the second spur rack 47 will be disengaged from the incomplete spur gear 46, and the second spur rack 47 will move backward and reset under the tension of the tension spring 49. Therefore, through the cooperation of the inner ratchet 45, the incomplete spur gear 46 and the second spur rack 47, the second spur rack 47 can move forward and then quickly move backward and reset, and can move back and forth reciprocatingly; the left and right sides of the front end surface of the U-shaped frame 17 are respectively fixed with arch seats, and the limit shaft 58 is fixed to the inner walls of the two arch seats, which is equivalent to the limit shaft 58 being fixed to the front end of the U-shaped frame 17, and the swing rod 55 is rotatably connected to the limit shaft 58. , so that the swing rod 55 and the knocking ball 56 can swing back and forth. Through the connection rod, multiple swing rods 55 and the knocking ball 56 can swing synchronously. Through the connection of the first connecting rod 48, the second spur rack 47 and the connecting rod, when the second spur rack 47 moves forward, it can drive the lower end of the first connecting rod 48 to move forward, and the upper end of the first connecting rod 48 will drive the connecting shaft 57, the swing rod 55 and the knocking ball 56 to swing upward. When the second spur rack 47 moves backward quickly, it will drive the lower end of the first connecting rod 48 to move backward quickly, and the upper end of the first connecting rod 48 will pull the swing rod 55 and the knocking ball 56 to move backward quickly. The knocking ball 56 can swing and hit the protective net 3 when it swings backward rapidly, thereby knocking the protective net 3 to clean off the dust adhering to the protective net 3; and under the mutual cooperation of the inner ratchet 45 and the ratchet 44, when the winding shaft 23 rotates forward and the protective net 3 is unfolded, the corresponding incomplete spur gear 46 and the inner ratchet 45 will not rotate, that is, the knocking ball 56 will not work; when the winding shaft 23 rotates reversely and the protective net 3 is folded, the corresponding incomplete spur gear 46 and the inner ratchet 45 rotate reversely with the winding shaft 23, and the corresponding knocking ball 56 can work normally, that is, the knocking ball 56 will work only when the protective net 3 is folded.

[0054] The front ends of the second spur racks 47 are fixedly connected with third sliding pins 51 , and the front and rear sides of the front end surface of the U-shaped seat 14 are fixedly connected with guide plates 52 , which are respectively provided with first vertical surfaces 54 and first inclined surfaces 53 that match the third sliding pins 51 .

[0055] like Fig.17As shown, by cooperating with the third sliding pin 51 and the guide plate 52, when the U-shaped frame 17 is at the lower end position, the second spur rack 47 is at the front end position, that is, the knocking ball 56 is at the upper end position. At this time, the knocking ball 56 can be away from the protective net 3 and no longer contact it, that is, it does not affect the deployment of the protective net 3; the third sliding pin 51 and the second spur rack 47 can always have a backward driving force under the tension of the tension spring 49, that is, the third sliding pin 51 can always contact and mesh with the first inclined surface 53 or the first vertical surface 54; when the U-shaped frame 17, the second spur rack 47, the third sliding pin 51, etc. move downward from the upper end position, the third sliding pin 51 can meet and mesh with the first inclined surface 53, and the third sliding pin 51 will be on the first inclined surface 5 3, the third sliding pin 51 and the second spur rack 47 can be driven to move downward and forward at the same time. When the U-shaped frame 17, the third sliding pin 51, etc. continue to move downward, the third sliding pin 51 can be moved downward to meet and mesh with the first vertical surface 54. At this time, the third sliding pin 51 and the second spur rack 47 are at the front end position and no longer move forward, that is, the corresponding knocking ball 56 moves upward to the top position, and the protective net 3 can be unfolded at this time. When the protective net 3 needs to be folded, by driving the U-shaped frame 17 to move upward to the top position, that is, when the third sliding pin 51 moves upward to the top position, the corresponding third sliding pin 51 and the second spur rack 47 move backward to the top position, and the knocking ball 56 can work normally at this time.

[0056] When the present invention is in use, the protective net 3 can be rolled up or unfolded when the reel-up shaft 23 rotates, and the other end of the protective net 3 can be fixed by the end fixing plate 2 and the fixing pile 4, so that the protective net 3 is fixed on the slope for protection; after the protective net 3 is unfolded, the height position of the protective net 3 can be adjusted by the U-shaped frame 17 that can move up and down, so that the protective net 3 is close to the slope surface, and the protection effect is further improved; when the protective net 3 is stored, the U-shaped frame 17 is moved upward by the scraper bar 33, so that the protective net 3 at the lower end of the U-shaped frame 17 is separated from the contact with the ground, which is convenient for storing the protective net 3, and when the U-shaped frame 17 moves to the top end, the scraper bar 33 can contact the protective net 3, and when the reel-up shaft 23 rotates, the scraper bar 33 can contact the protective net 3. When the protective net 3 is rolled up and moved, the scraper bar 33 can scrape the protective net 3, thereby removing the soil adhered to the protective net 3. When the protective net 3 continues to be unfolded and used, the U-shaped frame 17 is driven to move downward to the specified position. At this time, the scraper bar 33 will be out of contact with the protective net 3, that is, the corresponding protective net 3 will no longer be contacted and scraped when it is unfolded and moved; through the provision of multiple knocking balls 56, when the U-shaped frame 17 is at the top position and the winding shaft 23 rotates to make the protective net 3 roll up and move, the knocking balls 56 can reciprocately knock on the protective net 3, and the protective net 3 will continue to oscillate under the knocking, which can further remove the soil adhered to the protective net 3. Through the cooperation of the scraper bar 33 and the knocking balls 56, the protective net 3 can be comprehensively cleaned.
