Description

Technical Field

[0001] The invention relates to the field of fruit and vegetable fluid replenishment, in particular to a fruit tree hanging needle type fluid replenishment device based on the Internet of Things. Background Art

[0002] The main purpose of fruit tree hanging bag rehydration is to supplement nutrition, promote growth, and prevent and control diseases and pests; by providing the necessary nutrient solution to fruit trees, this technology has less pollution to the environment, has direct efficacy, and is an effective way to maintain normal metabolism of fruit trees.

[0003] However, the current fruit tree hanging bags cannot be reused, and the cost of refilling the fruit and vegetable hanging bags is high. In addition, the hanging bags are disposable items, which means that when refilling the fruit trees, not only do the hanging bags need to be installed, but the hanging bags also need to be removed after the refilling is completed. Fruits and vegetables need to be refilled about 2-3 times a year, which makes the hanging bags heavy and costly. Moreover, during the hanging process, the hanging bags can only adjust the flow rate by manually adjusting the valve on the hanging needle. When the refilling efficiency of the hanging bags needs to be adjusted more, it is difficult to complete the operation. The adjustment process undoubtedly increases the huge workload. It is also impossible to control and monitor the flow rate in real time.

[0004] During the process of rehydration, the liquid needs to be properly pressured to allow the liquid to enter the inside of the fruit tree. However, excessive pressure inside the hanging bag can easily damage the hanging bag and cause leakage. During the pressurization process, the hanging bag and the end cap may separate. The internal pressurization of the hanging bag increases the pressure on the hanging needle, which may cause the needle of the hanging needle to separate from the fruit tree during the pressurization process. When not in use, the hanging needle can be removed from the fruits and vegetables and placed under the hanging bag to prevent the hanging needle from growing into the inside of the fruit tree after the rehydration is completed.

[0014] Beneficial effects:

[0015] (1) The rehydration system is connected through a liquid medicine pipeline. The rehydration system can transport liquid to the top of each corresponding fruit tree. Then the hanging bag is connected to the rehydration system. The rehydration system is connected with a solenoid valve. The solenoid valve can be connected through a mobile phone APP. The solenoid valve controls the liquid flow rate inside the rehydration system; and the flow rate of the rehydration system can be remotely controlled. The hanging bag can be reused to save costs, and the hanging bag has a certain pressure resistance to prevent the hanging bag from breaking during the rehydration process; the hanging bag and the rehydration system are separated by the cooperation of the connecting mechanism and the locking mechanism; when the connecting mechanism and the locking mechanism need to be separated, the unlocking component is turned, the unlocking component blocks the connecting mechanism, and the unlocking component pushes the connecting mechanism to separate the connecting mechanism from the locking mechanism, so that the rehydration system can be separated under pressure. When separated, the connecting mechanism is closed and the liquid medicine inside the hanging bag is sealed. When pressurized, the limiting mechanism is moved out of the inside of the hanging needle and stuck in the inside of the fruit tree, so that the hanging needle will not be separated from the fruit tree when pressurized.

[0016] (2) The unlocking mechanism is set up so that the outer valve body and the inner valve body can be unlocked when it is necessary to separate them. The push rod is rotated and moved until the push rod is squeezed under the stop rod and slides from under the stop rod to the other side of the stop rod. At this time, the stop rod is limited. When the push rod needs to be reset, the shift block is moved upward, and the shift block drives the stop rod upward, so that the push rod enters the end of the slide groove, so that the through groove and the injection groove are aligned. At this time, the reset connection is completed. The process is simple and easy to operate, and can effectively unlock and lock the connection between the outer valve body and the inner valve body.

[0017] (3) When the injection increases the pressure, the amount of liquid flowing into the guide groove increases, and the liquid pushes the elastic sheet to move. The two ends of the elastic sheet are fixed inside the hanging needle, and the elastic sheet is deformed. The elastic sheet changes from being concave to convex on both sides. The elastic sheet drives the extrusion block to move, and the extrusion block moves and squeezes on the limit rod. The limit rod rotates around the rotating pin. The rotation of the limit rod drives the abutment block to move. The abutment block moves and is stuck inside the fruit tree. At this time, when the limit rod rotates to the maximum angle, the limit block now rotates with the limit rod. When the pressure inside the hanging needle is too high, the hanging needle will have a backward thrust. The limit block prevents the limit rod from rotating too much and deforming; when the hanging needle needs to be removed, the hanging needle is pushed to move inside the fruit tree. At this time, the fruit tree squeezes the limit rod, and the limit rod will be completely retracted under the action of the squeezing force until it is reset. When the limit rod is reset, the limit rod pushes the elastic sheet from convex to concave. At this time, the elastic sheet pulls the sixth elastic part to reset. The sixth elastic part is in a natural state at this time. The sixth elastic part pulls the limit rod to prevent the limit rod from rotating outward from the hanging needle during the process of pulling it out, and being stuck inside the fruit tree, making the disassembly process more convenient.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] In one embodiment, please refer to the attached manual. Figure 1-10As shown, the present invention discloses a fruit tree hanging needle type fluid replenishment device based on the Internet of Things, comprising a hanging bag 1, wherein the hanging bag 1 is provided with a snap-fit ​​mechanism 2 connected to a fluid replenishment system, wherein the snap-fit ​​mechanism 2 is used to connect to the fluid replenishment system to input the medicine into the interior of the hanging bag 1; the hanging bag 1 is provided with a connecting mechanism 5, wherein the connecting mechanism 5 is installed inside the snap-fit ​​mechanism 2, and when the connecting mechanism 5 is disassembled, the hanging bag 1 is separated from the fluid replenishment system; the hanging bag 1 is provided with a fluid replenishment tube 3, wherein a plurality of hanging needles 4 are provided at the end of the fluid replenishment tube 3, wherein the hanging needles 4 are used to be inserted into the interior of a fruit tree for fluid replenishment, and a limiting mechanism 7 is provided on the hanging needles 4, wherein the limiting mechanism 7 prevents the hanging needles 4 from being separated from the fruit tree; the snap-fit ​​mechanism 2 is provided with an unlocking component 6, wherein the unlocking component 6 is used to promote the separation of the snap-fit ​​mechanism 2 and the connecting mechanism 5.

[0032] The rehydration system is connected through a liquid medicine pipeline. The rehydration system can transport the liquid to the top of each corresponding fruit tree, and then the hanging bag 1 is connected to the rehydration system. The rehydration system is connected with a solenoid valve, which can be connected through a mobile phone APP. The solenoid valve controls the liquid flow rate inside the rehydration system; and the flow rate of the rehydration system can be remotely controlled. The hanging bag 1 can be reused to save costs, and the hanging bag 1 has a certain pressure resistance to prevent the hanging bag 1 from breaking during the rehydration process; the hanging bag 1 and the rehydration system are separated by the cooperation of the connecting mechanism 5 and the locking mechanism 2; when the connecting mechanism 5 and the locking mechanism 2 need to be separated, the unlocking component 6 is turned, and the unlocking component 6 blocks the connecting mechanism 5. At the same time, the unlocking component 6 pushes the connecting mechanism 5, so that the connecting mechanism 5 is separated from the locking mechanism 2, so that the rehydration system can be separated under pressure. When separated, the connecting mechanism 5 is closed, and the liquid medicine inside the hanging bag 1 is sealed. When pressure is applied, the limiting mechanism 7 is moved out from the interior of the hanging needle 4 and stuck in the interior of the fruit tree, so that the hanging needle 4 will not be separated from the fruit tree when pressure is applied.

[0033] The connecting mechanism 5 includes an inner valve body 51 arranged on the top of the hanging bag 1, a support plate 52 is arranged inside the inner valve body 51, and a plurality of openings are arranged on the support plate 52; a third elastic member 53 is arranged below the support plate 52, a movable plate 54 is arranged below the third elastic member 53, the third elastic member 53 is used to push the movable plate 54 to reset, an arc groove 55 is arranged on the lower surface of the movable plate 54, a sealing ring 56 is arranged at the bottom of the inner valve body 51, the sealing ring 56 and the arc groove 55 are squeezed and sealed, an outer spiral 58 is arranged on the inner valve body 51, a through groove 511 is arranged at the bottom of the inner valve body 51, an ejection assembly 57 is arranged inside the inner valve body 51, and the ejection assembly 57 is located in the gap of the outer spiral 58, and the ejection assembly 57 is engaged with the engaging mechanism 2. The connecting mechanism 5 also includes an elastic plate 510 arranged on both sides of the through groove 511, and a rubber pad 512 is arranged at the bottom of the elastic plate 510, and the rubber pad 512 has a corrugated structure; a fifth elastic member 513 is arranged inside the elastic plate 510, and the elastic plate 510 and the rubber pad 512 form a closed inner cavity 59; the inner cavity 59 is filled with hydraulic oil, and when the elastic plate 510 moves to squeeze the inner cavity 59, the hydraulic oil in the inner cavity 59 enters the interior of the ejection component 57, and the ejection component 57 moves and enters the interior of the locking mechanism 2. The ejection assembly 57 includes a chamber 573 and an oil groove 571 arranged on the inner valve body 51, one end of the oil groove 571 extends into the inner cavity 59, and the other end is communicated with the chamber 573; a fourth elastic member 572 is arranged inside the chamber 573, a push rod 575 is arranged inside the chamber 573, a reserved groove 574 is arranged above the push rod 575, and the reserved groove 574 is communicated with the chamber 573, the fourth elastic member 572 is sleeved with the push rod 575, and the fourth elastic member 572 is used to push the push rod 575 to reset.

[0034] The connecting mechanism 5 is connected to the engaging mechanism 2 by the arrangement; when the engaging mechanism 2 and the connecting mechanism 5 need to be connected, the engaging mechanism 2 is rotated, and the engaging mechanism 2 and the connecting mechanism 5 are engaged with each other in a spiral manner. When the engaging mechanism 2 and the connecting mechanism 5 are connected in place, the ejection assembly 57 is engaged with the engaging mechanism 2; the movable plate 54 is pushed up by the engaging mechanism 2, and the movable plate 54 moves up and is compressed by the third elastic member 53, so that the through groove 511 is opened. When the through groove 511 is opened, the liquid can flow from the inside of the inner valve body 51; in order to allow the liquid to enter the inside of the fruit tree, it is necessary to increase the flow rate of the solenoid valve, thereby increasing the pressure inside the inner valve body 51. When the pressure of the liquid inside the through groove 511 is increased, the liquid will squeeze the elastic plate 510, and the elastic plate 510 is squeezed and moved by the liquid. When the elastic plate 510 moves, the elastic plate 510 drives the rubber pad 512 to move. The movement of the rubber pad 512 will squeeze the inner cavity 59, and the inner cavity 59 will shrink. The hydraulic oil inside the inner cavity 59 will be squeezed, and the hydraulic oil is compressed and enters the interior of the oil groove 571. The hydraulic oil inside the oil groove 571 enters the interior of the chamber 573, and the hydraulic oil pushes the push rod 575 to move. When the push rod 575 moves, the fourth elastic member 572 is stretched, and the push rod 575 moves outward from the interior of the chamber 573, and the push rod 575 enters the interior of the locking mechanism 2; at this time, the locking mechanism 2 and the inner valve body 51 are fixed; when the liquid pressure continues to increase, the elastic plate 510 continues to move, and the movement of the elastic plate 510 continues to squeeze the hydraulic oil inside the oil groove 571, and the hydraulic oil pushes the push rod 575, and continues to move into the interior of the locking mechanism 2, until the push rod 575 is pushed under the reserved groove 574, the reserved groove 574 and the chamber 573 are connected, and the hydraulic oil enters the reserved groove 574 from the chamber 573.

[0035] When the locking mechanism 2 is removed from the inner valve body 51, the bottom of the movable plate 54 does not contact the locking mechanism 2. Under the push of the third elastic member 53, the movable plate 54 moves downward and makes the arc groove 55 fit on the sealing ring 56. The sealing ring 56 is squeezed so that the arc groove 55 is blocked by the sealing ring 56. At this time, the through groove 511 is blocked, and the elastic plate 510 is not squeezed by the liquid pressure. The elastic plate 510 is reset, and the fifth elastic member 513 is reset. Under the push of the fifth elastic member 513 and the elastic action of the elastic plate 510 itself, the inner cavity 59 is reset, and the hydraulic oil in the inner cavity 59 enters the interior of the inner cavity 59, and the hydraulic oil in the reserved groove 574 flows back.

[0036] The engaging mechanism 2 includes an outer valve body 21 that is screwed with the inner valve body 51, a spiral groove 29 is provided on the inner wall of the outer valve body 21, the spiral groove 29 cooperates with the outer spiral 58, a rod groove 23 is provided inside the outer valve body 21, a clamping rod 22 is provided inside the rod groove 23, a first elastic member 24 is sleeved on the clamping rod 22, and the first elastic member 24 is used to push the clamping rod 22 to reset; the clamping rod 22 moves to the inside of the chamber 573 and is clamped inside the chamber 573, and the outer valve body 21 is An extrusion rod 25 is provided inside, and the extrusion rod 25 abuts against the clamping rod 22. An adjusting component 26 matching with the extrusion rod 25 is provided at the bottom of the extrusion rod 25. The adjusting component 26 is used to adjust the position of the clamping rod 22. A bottom plate 27 is provided at the bottom of the outer valve body 21. An abutting rod 28 is provided on the bottom plate 27. The abutting rod 28 abuts against the movable plate 54. A plurality of injection grooves 210 are provided on the bottom plate 27. The adjusting component 26 synchronously adjusts the flow of the injection groove 210 when adjusting the position of the clamping rod 22. The adjusting assembly 26 includes a sealing plate 261 arranged inside the outer valve body 21, and a plurality of through holes 263 are arranged on the sealing plate 261, and the through holes 263 cooperate with the liquid injection groove 210, and a lifting block 262 is arranged on the sealing plate 261, and the lifting block 262 is an arc-shaped structure, and the surface of the lifting block 262 is an inclined surface, and the top of the lifting block 262 abuts against the extrusion rod 25; a block groove 264 is arranged inside the outer valve body 21, and the lifting block 262 slides inside the block groove 264.

[0037] The inner valve body 51 and the outer valve body 21 can be easily disassembled by cooperating with the spiral groove 29 and the outer spiral 58; when the liquid pressure increases, the hanging bag 1 will be separated from the liquid replenishing system; in order to ensure that the hanging bag 1 can still be suspended on the liquid replenishing system when the liquid is pressurized; during the pressurization process, the inner valve body 51 and the outer valve body 21 are tightened, and the pressure of the pressurization increases, and the connection between the inner valve body 51 and the outer valve body 21 becomes more secure; when the outer valve body 21 and the inner valve body 51 are rotated into place, the top rod 575 is just aligned with the clamping rod 2 2. Initially, the locking rod 22 is located inside the rod groove 23; when the push rod 575 is squeezed into the rod groove 23, the push rod 575 is stuck in the rod groove 23. Since the outer spiral 58 and the thread groove are spirally matched, the push rod 575 is limited at this time, so that the outer valve body 21 and the inner valve body 51 will not separate, and are further limited; when the liquid pressure inside the inner valve body 51 increases, the length of the push rod 575 entering the rod groove 23 becomes larger, making it more difficult to separate the push rod 575 from the rod groove 23, thereby achieving a locking effect.

[0038] When the inner valve body 51 and the outer valve body 21 need to be separated, the top of the hanging bag 1 must be blocked after the separation to prevent the liquid inside the hanging bag 1 from being lost or contaminated; the unlocking component 6 is rotated, and the unlocking component 6 drives the sealing plate 261 to rotate inside the outer valve body 21. During the rotation of the sealing plate 261, the through hole 263 and the injection groove 210 are misaligned, so that the injection groove 210 is completely blocked. At this time, the top of the hanging bag 1 is blocked; when the sealing plate 261 is rotated, the sealing plate 261 drives the lifting block 262 to rotate synchronously, and the lifting block 262 rotates to push the extrusion rod 25 upward. When the extrusion rod 25 is pushed upward, the extrusion rod 25 pushes The movable latch rod 22 moves until the end of the latch rod 22 just moves to the end of the rod groove 23. When the latch rod 22 moves, the latch rod 22 pushes the top rod 575 to reset until the top rod 575 just separates from the rod groove 23. At this time, the outer valve body 21 is rotated to remove the outer valve body 21 from the inner valve body 51. This process is simple to operate and can seal the top port of the hanging bag 1 and release the lock between the outer valve body 21 and the inner valve body 51. Even when the fluid replenishment system is pressurized, the hanging bag 1 can be installed and disassembled, which is convenient for replacing the hanging bag 1. In the process of replacement, the fluid replenishment operation can be carried out quickly, thereby improving the fluid replenishment efficiency.

[0039] The unlocking assembly 6 includes a slide groove 62 opened on the outer valve body 21, a card groove 63 is arranged above the slide groove 62, and a push rod 61 is slidably arranged inside the slide groove 62; a yield groove 67 is arranged above the slide groove 62, and a blocking rod 64 is arranged inside the yield groove 67, and a shift block 65 is arranged on the outer wall of the blocking rod 64, and a sixth elastic member 66 is arranged on the top of the blocking rod 64, and the sixth elastic member 66 is used to push the blocking rod 64 to reset, and the bottom of the blocking rod 64 is an inclined surface, and the push rod 61 moves to squeeze the blocking rod 64.

[0040] The unlocking mechanism provided can unlock the outer valve body 21 and the inner valve body 51 when it is needed to separate them. The push rod 61 is rotated and the push rod 61 moves until the push rod 61 is squeezed under the baffle rod 64 and slides from under the baffle rod 64 to the other side of the baffle rod 64. At this time, the baffle rod 64 is limited. When it is necessary to reset the push rod 61, the shift block 65 is moved upward and the shift block 65 drives the baffle rod 64 upward so that the push rod 61 enters the end of the slide groove 62 so that the through groove 511 and the injection groove 210 are aligned. At this time, the reset connection is completed. The process is simple and easy to operate, and can effectively unlock and lock the connection between the outer valve body 21 and the inner valve body 51.

[0041] The limiting mechanism 7 includes a limiting rod 71 rotatably set on the hanging needle 4, and an abutment block 72 is set at the end of the limiting rod 71. A pin groove 74 is opened on the limiting rod 71, and a rotating pin 73 is rotatably set inside the pin groove 74. The rotating pin 73 is provided with a torsion spring, and the torsion spring is used to push the limiting rod 71 to reset. A seventh elastic member 79 and an elastic sheet 76 are provided inside the hanging needle 4, one end of the seventh elastic member 79 is connected to the limiting rod 71, and the other end of the seventh elastic member 79 abuts on the elastic sheet 76, and an extrusion block 77 is provided on the elastic sheet 76. A guide groove 78 is provided between the two elastic sheets 76, and the guide groove 78 is connected to the infusion tube 3. A limiting block 75 is provided inside the hanging needle 4, and the limiting block 75 is used to limit the rotation angle of the limiting rod 71.

[0042] In order to allow the replenishing liquid to quickly enter the interior of the fruit tree, it is usually possible to apply pressure to the liquid by means of pressurization, so that the liquid can quickly enter the interior of the fruit tree from the hanging needle 4. As the pressure increases, the hanging needle 4 may be detached from the interior during the process. Since there are many trees inside the orchard, when the hanging needle 4 is detached from the interior of the fruit tree, a large amount of manpower is required to install the hanging needle 4; therefore, the hanging needle 4 is directly limited on the fruit tree by the limiting mechanism 7, so that the hanging needle 4 is not separated from the fruit tree during the pressurization process, thereby ensuring the efficiency of the injection. When the injection pressure increases, more liquid flows into the guide groove 78, and the liquid pushes the elastic sheet 76 to move. The two ends of the elastic sheet 76 are fixed inside the hanging needle 4, and the elastic sheet 76 is deformed. The elastic sheet 76 changes from concave to convex on both sides, and the elastic sheet 76 drives the extrusion block 77 to move. The extrusion block 77 moves and squeezes on the limit rod 71. The limit rod 71 rotates around the rotating pin 73. The rotation of the limit rod 71 drives the abutment block 72 to move, and the abutment block 72 moves and is stuck inside the fruit tree. At this time, when the limit rod 71 rotates to the maximum angle, the limit block 75 now rotates with the limit rod 71. When the pressure inside the hanging needle 4 is too high, the hanging needle 4 will have a backward thrust.

[0043] When the present invention is in use, the liquid replenishing system is first installed on the fruit tree, and the liquid replenishing system can be adjusted by a mobile phone to control the flow rate inside the liquid replenishing system and realize real-time monitoring; the hanging bag 1 is installed on the liquid replenishing system, and the outer valve body 212 is rotated so that the spiral groove 29 and the outer spiral 58 provided on the outer valve body 21 cooperate with each other. When the outer valve body 21 and the inner valve body 51 are rotated into place, the push rod 575 is just aligned with the clamping rod 22. Initially, the clamping rod 22 is located inside the rod groove 23; when the push rod 575 is squeezed into the inside of the rod groove 23, the push rod 575 is stuck in the inside of the rod groove 23. Since the outer spiral 58 and the threaded groove are spirally matched, the push rod 575 is limited at this time, so that the outer valve body 21 and the inner valve body 51 will not separate and are thus limited. When the inner valve body 51 and the outer valve body 21 need to be separated, the push rod 61 is rotated, and the push rod 61 moves until the push rod 61 is squeezed under the blocking rod 64 and slides under the blocking rod 64 to enter the other side of the blocking rod 64. The push rod 61 drives the sealing plate 261 to rotate inside the outer valve body 21. During the rotation of the sealing plate 261, the through hole 263 and the injection groove 210 are misaligned, so that the injection groove 210 is completely blocked. At this time, the top of the hanging bag 1 is blocked; when the sealing plate 261 is rotated, 1, the sealing plate 261 drives the lifting block 262 to rotate synchronously, and the lifting block 262 rotates to lift the extrusion rod 25 upward. When the extrusion rod 25 is lifted upward, the extrusion rod 25 pushes the clamping rod 22 to move until the end of the clamping rod 22 just moves to the end of the rod groove 23. When the clamping rod 22 moves, the clamping rod 22 pushes the ejector rod 575 to reset until the ejector rod 575 just separates from the rod groove 23. At this time, the outer valve body 21 is rotated to be removed from the inner valve body 51.When it is necessary to connect the locking mechanism 2 and the connecting mechanism 5 in place, at this time, the push rod 575 is locked with the rod groove 23; the movable plate 54 is pushed upward by the locking mechanism 2, and the movable plate 54 moves up and the third elastic member 53 is compressed, so that the through groove 511 is opened. When the through groove 511 is opened, the liquid can flow from the inside of the inner valve body 51; in order to allow the liquid to enter the interior of the fruit tree, it is necessary to increase the flow rate of the solenoid valve, thereby increasing the pressure inside the inner valve body 51. When the pressure of the liquid inside the through groove 511 is increased, the liquid will squeeze the elastic plate 510, and the elastic plate 510 will be squeezed and moved by the liquid. When the elastic plate 510 moves, the elastic plate 510 drives the rubber pad 512 to move, and the movement of the rubber pad 512 will squeeze the inner cavity 59. The inner cavity 59 shrinks, and the hydraulic oil inside the inner cavity 59 will be squeezed , the hydraulic oil is compressed and enters the interior of the oil groove 571, the hydraulic oil inside the oil groove 571 enters the interior of the chamber 573, and the hydraulic oil pushes the push rod 575 to move. When the push rod 575 moves, the fourth elastic member 572 is stretched, and the push rod 575 moves outward from the interior of the chamber 573, and the push rod 575 enters the interior of the locking mechanism 2; at this time, the locking mechanism 2 and the inner valve body 51 are fixed; when the liquid pressure continues to increase, the elastic plate 510 continues to move, and the elastic plate 510 moves and continues to squeeze the hydraulic oil inside the oil groove 571, and the hydraulic oil pushes the push rod 575, and continues to move into the interior of the locking mechanism 2, until the push rod 575 is pushed under the reserved groove 574, the reserved groove 574 and the chamber 573 are connected, and the hydraulic oil enters the reserved groove 574 from the chamber 573. When the locking mechanism 2 is removed from the inner valve body 51, the bottom of the movable plate 54 does not contact the locking mechanism 2. Under the push of the third elastic member 53, the movable plate 54 moves downward and makes the arc groove 55 fit on the sealing ring 56. The sealing ring 56 is squeezed so that the arc groove 55 is blocked by the sealing ring 56. At this time, the through groove 511 is blocked, and the elastic plate 510 is not squeezed by the liquid pressure. The elastic plate 510 is reset, and the fifth elastic member 513 is reset. Under the push of the fifth elastic member 513 and the elastic action of the elastic plate 510 itself, the inner cavity 59 is reset, and the hydraulic oil in the inner cavity 59 enters the interior of the inner cavity 59, and the hydraulic oil in the reserved groove 574 flows back.When the injection pressure increases, more liquid flows into the guide groove 78, and the liquid pushes the elastic sheet 76 to move. The two ends of the elastic sheet 76 are fixed inside the hanging needle 4, and the elastic sheet 76 is deformed. The elastic sheet 76 changes from being concave to convex on both sides, and the elastic sheet 76 drives the extrusion block 77 to move. The extrusion block 77 moves and is squeezed on the limit rod 71. The limit rod 71 rotates around the rotating pin 73. The rotation of the limit rod 71 drives the abutment block 72 to move. The abutment block 72 moves and is stuck inside the fruit tree. At this time, when the limit After the rod 71 rotates to the maximum angle, the limit block 75 now stops the limit rod 71 from rotating. When the pressure inside the hanging pin 4 is too large, the hanging pin 4 will have a backward thrust. At this time, the limit block 75 prevents the limit rod 71 from rotating too much and deforming. When the hanging pin 4 needs to be removed, the hanging pin 4 is pushed to move inside the fruit tree. At this time, the fruit tree squeezes the limit rod 71, and the limit rod 71 will be completely retracted under the action of the squeezing force until it is reset. When the limit rod 71 is reset, the limit rod 71 pushes the elastic sheet 76 from convex to concave.
