[0002] Forest tending refers to the process of appropriately managing and caring for forests to promote their healthy growth and sustainable development. Forest tending includes the following aspects: thinning, branch pruning, regeneration, pest control, etc. Forest tending can not only improve the productivity and economic benefits of forests, but also enhance their ecological functions, such as carbon sequestration, soil and water conservation, and biodiversity protection.

[0003] Existing protection devices for forest tending generally fix the base of trees to prevent the trees from tilting or falling and improve wind resistance, etc. However, this kind of fixation usually uses support rods, binding ropes and other methods, and the operation is relatively cumbersome; and its function is single and does not have other protection functions, making it difficult to meet other needs of forest tending.

Opposite corners at the top of the base are vertically welded with first support columns, and the tops of the two first support columns are horizontally welded with the same cross plate. An opening is provided at the center of the cross plate. On both sides of the top of the cross plate, first support rods are vertically welded, and the same gear ring is horizontally welded to the tops of the two first support rods. At the bottom of the two brush rollers, support shafts are vertically welded, and gears are welded to both support shafts. Both gears are engaged with the inner side of the gear ring. A circular ring is rotatably connected to the top of the cross plate, and the bottom ends of the two support shafts are rotatably connected to the top of the circular ring. A belt is connected between the circular ring and the rotating shaft. Second support rods are vertically welded to the four corners at the bottom of the annular insecticidal box, and the bottom ends of the four second support rods are welded to the top of the cross plate.

[0009] As a further technical solution of the present invention, the water supply mechanism includes a water pump. The water pump is fixedly installed on one side of the inner bottom of the rectangular box. The water inlet of the water pump is located inside the rectangular box. The water outlet of the water pump is vertically communicated with a water supply pipe. The top end of the water supply pipe penetrates through the filter screen and is communicated with the bottom of the annular pipe.

The lead screw is horizontally and rotatably connected to the inside of the C-shaped mounting plate. One end of the lead screw penetrates through the C-shaped mounting plate and is welded with a turntable. C-shaped moving plates are sleeved on both ends of the lead screw, and both C-shaped moving plates are connected to the lead screw by threads. The thread directions at both ends of the lead screw are opposite, and one end of each of the two C-shaped moving plates is slidably connected to the C-shaped mounting plate. The other ends of the two C-shaped moving plates horizontally penetrate through and are slidably connected to guide rods. The other ends of the two guide rods are vertically welded with L-shaped plates. Springs are horizontally welded between the L-shaped plates and the C-shaped moving plates. First fixing plates are respectively welded to the front ends of the two L-shaped plates. Telescopic sleeve rods are vertically welded to the tops of the two L-shaped plates, and connecting plates are welded to the tops of the two telescopic sleeve rods. Second fixing plates are respectively welded to one side of the two connecting plates.

[0011] A protection method for forest tending, comprising the following specific steps: S1: Place the base on the ground so that the circular groove is directly above the planting pit of the planted tree, and insert the four pointed cones into the soil to fix the device; S2: After the tree is planted, use the turntable to drive the screw rod to rotate, drive the two C-shaped moving plates to move towards each other, the two C-shaped moving plates drive the two L-shaped plates to move towards each other through the guide rods, the two L-shaped plates drive the two first fixing plates to move towards each other, and the two L-shaped plates drive the two second fixing plates to move towards each other through the telescopic sleeve rods and connecting plates until the two first fixing plates and the two second fixing plates are both clamped on both sides of the tree base, playing a role in fixing the tree base. The operation of supporting and fixing the tree base is relatively simple, time-saving and labor-saving; S3: When it rains, the rainwater passes through the filter screen to filter out impurities and then enters the rectangular box for storage; S4: At night, turn on the ultraviolet lamp tube to emit ultraviolet light source, which will attract the nearby mosquitoes to gather towards the ultraviolet lamp tube. The mosquito killing power grid on the outer side of the annular insect killing box can electrocute the gathered mosquitoes to death, thereby reducing the nearby mosquitoes. The dead mosquitoes fall down along the annular guide plate from the circular groove onto the soil surface at the root of the tree, and their corpses can play a role in fertilizing the tree after rotting; S5: Some of the corpses of the mosquitoes electrocuted to death will remain on the surface of the mosquito killing power grid. Regularly start the rotating motor to drive the rotating shaft to rotate. The rotating shaft drives the ring to rotate through the belt. The ring drives the two brush rollers to revolve through the two support shafts. The two support shafts also drive the two gears to revolve at the same time. Because the gear meshes with the gear ring, the gear drives the brush roller to rotate selflessly during the revolution process through the support shaft, thereby driving the two brush rollers to revolve and rotate selflessly to brush off the mosquito corpses adhered to the surface of the mosquito killing power grid, preventing it from affecting the subsequent insect killing work; S6: At the same time, start the water pump to pump the rainwater in the rectangular box, and through the water supply pipe, the annular pipe and multiple water outlet branch pipes, it is sprayed obliquely downward by multiple nozzles, not only watering and irrigating the tree, but also spraying it on the surface of the mosquito killing power grid to cooperate with the brush roller to brush off the mosquito corpses; S7: As the tree grows thicker, the tree squeezes the two first fixing plates and the two second fixing plates to both sides. The two first fixing plates and the two second fixing plates drive the two L-shaped plates to move to both sides and squeeze the springs. The springs generate a rebound force so that the two first fixing plates and the two second fixing plates still fix on both sides of the tree, so that it can adapt to any diameter of the tree base as the tree grows and always support and fix the tree base; S8: As the tree grows taller, because the two second fixing plates are always fixed on both sides of the tree, they also move upward and stretch the telescopic sleeve rods as the tree grows taller, so that the trunk of the tree is restricted between the two first fixing plates and the two second fixing plates, thus ensuring that the trunk of the tree always grows vertically and preventing it from tilting.

[0012] The beneficial effects of the present invention are as follows: 1. The operation of supporting and fixing the base of the tree is relatively simple, time-saving and labor-saving, and it can adapt to any diameter of the tree base as the tree grows, always support and fix the tree base, and can also ensure that the trunk of the tree grows vertically and prevent it from tilting.

[0013] 2. It can attract mosquitoes near the tree and electrocute them to reduce the number of mosquitoes nearby, and can brush off the mosquito corpses adhering to the surface of the mosquito-killing power grid to prevent affecting subsequent pest control work. After the mosquito corpses rot, they can also fertilize the tree.

[0014] 3. It can collect rainwater for storage and regularly spray it to irrigate the tree, and can also spray it on the surface of the mosquito-killing power grid to cooperate with the roller brush to brush off the mosquito corpses. Description of the Drawings

[0035] A protection method for forest tending includes the following specific steps: S1: Place the base 10 on the ground so that the circular groove 11 is directly above the planting pit for the tree to be planted, and insert the four tapered cones 9 into the soil to fix the device. S2: After the tree is planted, use the turntable 43 to drive the lead screw 37 to rotate, driving the two C-shaped moving plates 38 to move towards each other. The two C-shaped moving plates 38 drive the two L-shaped plates 39 to move towards each other through the guide rods 42. The two L-shaped plates 39 drive the two first fixing plates 24 to move towards each other. The two L-shaped plates 39 drive the two second fixing plates 22 to move towards each other through the telescopic sleeve rods 23 and the connecting plates 40 until the two first fixing plates 24 and the two second fixing plates 22 are both clamped on both sides of the base of the tree, playing a role in fixing the base of the tree. S3: When it rains, the rainwater passes through the filter screen 6 to filter out impurities and then enters the loop-shaped box 13 for storage. S4: At night, turn on the ultraviolet lamp tube 28 to emit ultraviolet light source, which will attract the nearby mosquitoes to gather towards the ultraviolet lamp tube 28.

S5: Regularly start the rotating motor 18 to drive the rotating shaft 17 to rotate. The rotating shaft 17 drives the ring 32 to rotate through the belt 44. The ring 32 drives the two brush rollers 14 to revolve through the two support shafts 35. The two support shafts 35 simultaneously drive the two gears 30 to revolve. Because the gear 30 meshes with the gear ring 29, the gear 30 drives the brush roller 14 to rotate on its own axis during the revolution process through the support shaft 35, thereby driving the two brush rollers 14 to revolve and rotate on their own axes at the same time to brush off the mosquito corpses adhering to the surface of the mosquito killing power grid. S6: At the same time, start the water pump 20 to pump the rainwater in the loop-shaped box 13. The rainwater passes through the water supply pipe 21, the annular pipe 3 and multiple water outlet branch pipes 2, and is sprayed obliquely downward by multiple nozzles 5, not only watering and irrigating the tree, but also spraying towards the surface of the mosquito killing power grid to cooperate with the brush roller 14 to brush off the mosquito corpses. S7: As the tree grows thicker, the tree squeezes the two first fixing plates 24 and the two second fixing plates 22 towards both sides. The two first fixing plates 24 and the two second fixing plates 22 drive the two L-shaped plates 39 to move towards both sides and squeeze the spring 41. The spring 41 generates a rebounding force so that the two first fixing plates 24 and the two second fixing plates 22 still fix on both sides of the tree, always supporting and fixing the base of the tree. S8: As the tree grows taller, because the two second fixing plates 22 always fix on both sides of the tree, they also move upward and stretch the telescopic sleeve rod 23 as the tree grows taller, restricting the trunk of the tree between the two first fixing plates 24 and the two second fixing plates 22.

[0036] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: the operation of supporting and fixing the base of the tree is relatively simple, time-saving and labor-saving, and it can adapt to any diameter of the base of the tree as the tree grows, and always support and fix the base of the tree. It can also ensure that the trunk of the tree grows vertically and prevent it from tilting; It can attract mosquitoes near the tree and electrocute them to death, reducing the mosquitoes in the vicinity. It can also brush off the mosquito corpses adhering to the surface of the mosquito-killing power grid to prevent affecting subsequent pest control work. After the mosquito corpses rot, they can also fertilize the tree; It can collect rainwater for storage and regularly spray water for watering the tree, and can also spray it on the surface of the mosquito-killing power grid to cooperate with the rolling brush to brush off mosquito corpses; By using the above methods in combination, multiple protections can be provided for the tree, avoiding single functions and meeting various needs of forest tending.

Both ends of the lead screw (37) are sleeved with C-shaped moving plates (38), and the two C-shaped moving plates (38) are both connected to the lead screw (37) by threads. The thread directions at both ends of the lead screw (37) are opposite, and one ends of the two C-shaped moving plates (38) are both slidably connected to the C-shaped mounting plate (36).

9. The protective device for forest tending according to claim 8, characterized in that, The other ends of the two C-shaped moving plates (38) both horizontally penetrate through and are slidably connected to a guide rod (42). The other ends of the two guide rods (42) are vertically welded with L-shaped plates (39). A spring (41) is horizontally welded between the L-shaped plate (39) and the C-shaped moving plate (38). The two first fixing plates (24) are respectively welded to the front ends of the two L-shaped plates (39). The tops of the two L-shaped plates (39) are both vertically welded with telescopic sleeve rods (23), and the tops of the two telescopic sleeve rods (23) are both welded with connecting plates (40). The two second fixing plates (22) are respectively welded to one sides of the two connecting plates (40).

10. The protection method of a protection device for forest tending according to claims 1-9, characterized in that, It includes the following specific steps: S1: Place the base (10) on the ground so that the circular groove (11) is directly above the planting pit of the planted tree, and the four pointed cones (9) are inserted into the soil to fix the device; S2: After the trees are planted, the turntable (43) is used to drive the lead screw (37) to rotate, driving the two C-shaped moving plates (38) to move towards each other. The two C-shaped moving plates (38) drive the two L-shaped plates (39) to move towards each other through the guide rods (42). The two L-shaped plates (39) drive the two first fixing plates (24) to move towards each other. The two L-shaped plates (39) drive the two second fixing plates (22) to move towards each other through the telescopic sleeve rods (23) and the connecting plates (40) until the two first fixing plates (24) and the two second fixing plates (22) are both clamped on both sides of the tree base, playing a role in fixing the tree base; S3: When it rains, the rainwater passes through the filter screen (6) to filter out impurities and then enters the loop-shaped box (13) for storage; S4: At night, when the ultraviolet lamp tube (28) is turned on to emit ultraviolet light source, it will attract the nearby mosquitoes to gather towards the ultraviolet lamp tube (28). The mosquito killing electric grid on the outer side of the annular insect killing box (1) electrocutes the gathered mosquitoes to death. The dead mosquitoes fall down along the annular guide plate (25) and fall from the round groove (11) onto the soil surface at the root of the tree; S5: Regularly start the rotating motor (18) to drive the rotating shaft (17) to rotate. The rotating shaft (17) drives the ring (32) to rotate through the belt (44). The ring (32) drives the two brush rollers (14) to revolve through the two support shafts (35). The two support shafts (35) simultaneously drive the two gears (30) to revolve. Because the gear (30) meshes with the gear ring (29), the gear (30) drives the brush roller (14) to rotate on its own axis during the revolution process through the support shaft (35), thereby driving the two brush rollers (14) to revolve and rotate on their own axes at the same time to brush off the mosquito corpses adhering to the surface of the mosquito killing electric grid; S6: At the same time, start the water pump (20) to pump the rainwater in the loop-shaped box (13). After passing through the water supply pipe (21), the annular pipe (3) and multiple water outlet branch pipes (2), it is sprayed obliquely downward by multiple nozzles (5), not only watering and irrigating the trees, but also spraying towards the surface of the mosquito killing electric grid to cooperate with the brush roller (14) to brush off the mosquito corpses; S7: As the trees grow thicker, the trees squeeze the two first fixing plates (24) and the two second fixing plates (22) towards both sides. The two first fixing plates (24) and the two second fixing plates (22) drive the two L-shaped plates (39) to move towards both sides and squeeze the springs (41). The springs (41) generate a rebound force so that the two first fixing plates (24) and the two second fixing plates (22) still fix on both sides of the trees, always supporting and fixing the tree base; S8: As the trees grow taller, because the two second fixing plates (22) are always fixed on both sides of the trees, they also move upward and stretch the telescopic sleeve rods (23) as the trees grow taller, restricting the tree trunks between the two first fixing plates (24) and the two second fixing plates (22).
