DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides an infusion device for preventing and controlling tree diseases and insect pests, comprising a hanging bag 1, which is connected to trees through a first binding strap 3, and a hanging ring 2 is provided on the top of the hanging bag 1 and on both sides of the top of the hanging bag 1, to which the first binding strap 3 is adapted. Through the setting of the hanging ring 2, the hanging bag 1 can be connected to the trees by hanging or binding, and the hanging bag 1 has a variety of fixing methods, thereby improving the adaptability of the infusion device.

[0022] An infusion catheter 4 is fixed to the bottom of the hanging bag 1, the other end of the infusion catheter 4 is connected to an infusion needle, and a flow rate regulator 5 is provided on the infusion catheter 4. Through the setting of the infusion catheter 4, the forest pest control liquid placed in the hanging bag 1 can be transported into the tree body along the infusion catheter 4 and the infusion needle.

[0023] The infusion needle includes a rotating cap 10, a connecting cap 6 and a needle tube 8. The end of the infusion catheter 4 away from the hanging bag 1 is movably connected to the middle of the rotating cap 10. The inner cavity of the other end of the rotating cap 10 is provided with a groove. The connecting cap 6 is movably connected to the inner cavity of the groove, and a sealing sheet is fixed to the inner wall of the groove. The sealing sheet can be made of rubber. By setting the sealing sheet, the sealing between the rotating cap 10 and the connecting cap 6 can be improved to avoid leakage. The other end of the connecting cap 6 is fixedly connected to the needle tube 8.

[0024] A support rod 11 is fixedly connected to the inner cavity of the rotating cap 10, and a ball screw 9 is fixedly connected to the other end of the support rod 11. The outer ring of the ball screw 9 is movably sleeved with a support rod 12. The support rod 12 is fixedly connected to the connecting cap 6, and the outer ring of the ball screw 9 is threadedly connected to a ball nut. A sealing plug 13 is fixed to the outer ring of the ball nut. The sealing plug 13 is movably connected to the inner cavity of the needle tube 8, and the inner diameter of the connecting cap 6 is larger than the inner diameter of the needle tube 8. The inner diameter of the needle tube 8 is matched with the outer diameter of the sealing plug 13. The distance between the support rod 12 and the needle tube 8 is larger than the width of the sealing plug 13. The size of the infusion needle is not limited here and is set according to demand.

[0025] From the above description of the infusion needle, it can be known that the user can drive the ball screw 9 to rotate by rotating the rotating cap 10. When the ball screw 9 rotates, the ball nut threadedly connected thereto can move in the direction of the ball screw 9. When the ball nut moves, it can drive the sealing plug 13 to move, and the support rod 12 can limit the sealing plug 13. When the sealing plug 13 contacts the support rod 12, the sealing plug 13 is separated from the needle tube 8, and the prevention liquid can be infused into the wood through the infusion needle. When the sealing plug 13 moves to the outside of the needle tube 8, the needle of the needle tube 8 can be blocked to prevent the infusion needle from being blocked by debris generated during the punching process when the infusion needle is inserted into the punched hole.

[0026] A sealing ring 7 is provided on the outer ring of one end of the needle tube 8 close to the connecting cap 6. The sealing ring 7 includes a cylindrical portion and a conical portion. The cylindrical portion is located on the side of the conical portion close to the connecting cap 6. By setting the sealing ring 7, the sealing between the needle tube 8 and the hole punched in the wood can be improved, leakage can be avoided and the reliability of fixing the infusion needle can be improved.

[0027] During use of the infusion device, one end of the infusion catheter 4 connected to the infusion needle is fixed to the tree through the second strap 14 to prevent the infusion catheter 4 from affecting the reliability of fixing the infusion needle. The second strap 14 is fixedly connected to the infusion catheter 4.

[0028] The first strap 3 and the second strap 14 both include a base strap 15, an airbag strap 16 is fixed to the inner side of the base strap 15, a deflation valve 17 is fixed to the side of the airbag strap 16 close to the base strap 15, and the other end of the deflation valve 17 is located outside the base strap 15. The length of the base strap 15 is fixed, and the base strap 15 is mesh-shaped. Through the setting of the base strap 15, the base strap 15 limits the length of the first strap 3 and the second strap 14, which is convenient for users to use the strap 1 3 and the strap 2 14 to tie the tree. The setting of the mesh base strap 15 increases the air permeability of the first strap 3 and the second strap 14. The side of the airbag strap 16 away from the base strap 15 is evenly provided with protrusions. Through the setting of the protrusions, the contact area between the airbag strap 16 and the tree can be reduced, which is convenient for the ventilation of the forest.

[0029] The deflation valve 17 includes a shaped shell 20, the inner cavity of which is connected to a movable mesh plate 18 via a spring 19, a sealing block 21 is fixed to the middle of the inner side of the movable mesh plate 18, a through hole 22 is provided on the side of the shaped shell 20 close to the sealing block 21, the sealing block 21 is in contact with the through hole 22, the shaped shell 20 is fixed to the airbag belt 16, and the inner cavity of the airbag belt 16 is connected to the inner cavity of the through hole 22, through the setting of the deflation valve 17, when the airbag belt 16 is squeezed, the gas in the airbag belt 16 will squeeze the sealing block 21, when the pressure on the sealing block 21 is greater than the pulling force of the spring 19, the sealing block 21 will separate from the through hole 22, and the excess gas in the airbag belt 16 will be discharged from the through hole 22, and the volume of the airbag belt 16 will be reduced.

[0030] From the above description of the first strap 3 and the second strap 14, it can be seen that during the binding process, the inner diameter of the ring structure formed by the first strap 3 and the second strap 14 can become smaller as the trees grow, thereby preventing the first strap 3 or the second strap 14 from affecting the growth of the trees.

[0031] In summary: when the infusion device for preventing and controlling tree diseases and insect pests is used, the hanging bag 1 is filled with liquid medicine for preventing and controlling tree diseases and insect pests. The user uses the first strap 3 to hang the hanging bag 1 at a suitable position of the tree, and punches a hole at the part of the tree to be injected. The punching position is located below the hanging bag 1, and the hole size is adapted to the needle tube 8. After the punching is completed, the user inserts the needle tube 8 into the hole. During the insertion of the needle tube 8, a part of the sealing plug 13 is located outside the needle tube 8. The sealing plug 13 blocks the needle tip of the needle tube 8 to prevent the needle tube 8 from being blocked. The sealing ring 7 increases the sealing between the needle tube 8 and the hole to prevent leakage and improve the reliability of the fixation of the infusion needle. After the needle tube 8 is fixed, the user rotates the rotating cap 10, and the rotating cap 10 drives the fixed cap 10 to rotate. The ball screw 9 connected to the tree rotates, and the rotation of the ball screw 9 causes the sealing plug 13 to move in the direction of the ball screw 9 until the sealing plug 13 can no longer move. At this time, the sealing plug 13 is separated from the needle tube 8, and the inner cavity of the infusion needle is in a smooth state. The liquid medicine in the hanging bag 1 can be injected into the tree along the infusion catheter 4 and the infusion needle. After the infusion needle is fixed to the tree, the position of the infusion catheter 4 is fixed by the second strap 14 to prevent the shaking of the infusion catheter 4 from affecting the infusion needle. During the growth of the tree, the tree will squeeze the airbag belt 16, so that the excess air in the airbag belt 16 is discharged through the deflation valve 17, resulting in a reduction in the volume of the airbag belt 16. The first strap 3 and the second strap 14 will not affect the growth of the tree.
