Description

Technical Field

[0001] The present invention relates to the field of agricultural irrigation, and specifically to an irrigation and fertilization device for agriculture and a usage method thereof. Background Art

[0002] Agricultural production refers to the process in which humans utilize the growth and reproduction functions of organisms and adopt artificial cultivation and management methods to obtain agricultural products. During the process of agricultural planting production, it is necessary to irrigate and spray plants. With the continuous development of agricultural modernization, frame-covered vegetable greenhouses with excellent heat preservation performance have gradually emerged, alleviating the situation of less vegetables in winter. During the process of growing vegetables in agricultural greenhouses, irrigation and spraying operations are essential.

[0003] The existing patent (publication number: CN119032836A) discloses an agricultural irrigation and spraying device for agricultural production, including a storage component. A hanging walking component is installed on the top of the storage component, and a driving component is arranged between the inside of the hanging walking component and the outside of the storage component. In this invention, when performing suspension movement spraying irrigation, only a tightened rope needs to be erected to achieve it. And during the spraying process, the servo motor for driving the device to move forward can simultaneously drive the water spraying pipe to swing and spray, further expanding the spraying irrigation range. The overall construction difficulty and cost are relatively low. At the same time, even if the storage tank is used without connecting to an external water pipe, the water inside can be pumped out without an additional power source and supplied to the water spraying pipe for agricultural irrigation and spraying. It has strong functionality and can avoid the drug precipitation in the irrigation water containing pesticides from clogging the water spraying pipe. The overall structure is simple and the function is practical. In the process of implementing this invention, the inventor found that at least the following problems in the prior art have not been solved: The existing agricultural irrigation can only achieve fixed-point irrigation spraying or swing-type irrigation spraying during the fertilization process. When using the swing type for agricultural spraying, if the planted crops are spaced relatively far apart from each other, the pesticides will be sprayed onto the areas between the crops, resulting in waste of pesticides.

Fixing rods are fixedly arranged at equal intervals on the limit card frame. An adjusting tooth plate is also arranged in the clamping cavity. Connecting rods are fixedly arranged at equal intervals on the adjusting tooth plate. An articulated frame is hinged between the fixing rod and the connecting rod. A spring piece is also sleeved on the fixing rod. Two ends of the spring piece are respectively connected with the clamping cavity of the limit card frame and the adjusting tooth plate. A resisting frame is fixedly arranged on the outer wall of the adjusting tooth plate. The resisting frame contacts the pressing end of the pressing valve. A resisting baffle extends towards the limit card frame from the first limit block. The resisting baffle abuts against the limit card frame.

[0010] Preferably, a transmission gear is also fixedly connected to the rotating rod. A rotating gear meshing with the transmission gear is rotatably arranged on the bearing housing. A rotating shaft in a compressed state is also rotatably arranged on the bearing housing. The rotating shaft is connected to the rotating gear in an axial manner. An internal ratchet pawl is fixedly arranged on the rotating shaft. An external ratchet disc is rotatably arranged on the bearing housing. The internal ratchet pawl abuts against the external ratchet disc. The external ratchet disc meshes with the adjusting tooth plate.

[0011] Preferably, a moving groove is also arranged on the bearing housing. A resisting rod slidably matched with the moving groove is fixedly connected to the limit card frame. A pressing frame is rotatably arranged on the bearing housing. A resisting spring is arranged between the pressing frame and the bearing housing. One side of the pressing frame is inclined, and the inclined end of the pressing frame contacts the top surface of the rotating shaft. A retaining pin is also rotatably arranged on the bearing housing. An elastic spring is arranged between the retaining pin and the bearing housing. One end of the retaining pin abuts against the outer wall of the rotating shaft. The end of the retaining pin away from the rotating shaft contacts the resisting rod.

[0012] Preferably, a method for using the agricultural irrigation and fertilization device includes the following steps: S1: When the driving rod rotates driven by the driving motor, the rotation of the driving rod will drive the clutch sleeve clamped on the driving rod to rotate. When the end face of the clutch sleeve with a concave setting contacts the conical surface on the first helical gear, the clutch sleeve will drive the first helical gear to rotate. When the first helical gear rotates, the first helical gear will drive the rotating helical gear to rotate. The rotating helical gear drives the rotating rod to continuously rotate, and the rotating rod will drive the swing fertilizing device to continuously swing reciprocally. Through the continuous reciprocal swing of the swing fertilizing device, the crops are sprayed reciprocally. When the end face of the clutch sleeve with a concave setting contacts the conical surface of the second helical gear, the second helical gear will drive the semi-helical gear to rotate. When the semi-helical gear rotates, it will drive the rotating helical gear to rotate intermittently. The intermittent rotation of the rotating helical gear causes the rotating rod to rotate intermittently. Thus, when the swing fertilizing device sprays the crops with a swing, it performs an intermittent swing; S2: The operator deflects the adjusting frame through the swing adjusting frame. When the adjusting frame deflects, the deflecting frame will be synchronously deflected driven by the tension spring between the adjusting frame and the deflecting frame. The deflection of the deflecting frame will drive the two clamping frames arranged in an articulated manner to shift towards one side. The two clamping frames will drive the clutch sleeve to contact the first helical gear or the second helical gear, so that the clutch sleeve can be closely attached to the first helical gear or the second helical gear, thereby realizing the switching of the friction transmission of the clutch sleeve to the first helical gear and the second helical gear; S3: When the rotating rod rotates, the rotating rod will drive the rotating frame to rotate. During the rotation of the positioning rod at the other end of the rotating frame, it will contact the chute on the swing frame, so that the swing frame can reciprocally swing on the top of the bearing housing driven by the positioning rod. The reciprocating swing of the swing frame drives several spray heads to be able to spray the crops reciprocally, improving the efficiency of crop irrigation and fertilization; S4: When the operator controls the adjusting device to make the clutch sleeve contact the first helical gear, the first limiting rod on the adjusting frame will drive the first limiting block to move upward. At this time, the contact baffle on the first limiting block will contact the outer wall of the limiting card frame, thereby limiting the limiting card frame. At this time, when the driving and rotating device drives the swing fertilizing device to swing reciprocally, the rotating rod on the swing fertilizing device will drive the transmission gear to rotate. The rotation of the transmission gear drives the rotating gear to rotate. The rotating gear drives the rotating shaft connected by the shaft to rotate. The inner ratchet claw on the rotating shaft contacts the outer ratchet disc, so that the outer ratchet disc rotates. After the outer ratchet disc contacts the adjusting tooth plate, since there is an articulated frame hinged between the adjusting tooth plate and the limiting card frame and they are connected by a spring piece, when the outer ratchet disc rotates and drives the adjusting tooth plate to move, the adjusting tooth plate will contract and move in the card cavity of the limiting card frame, and the limiting card frame will not slide on the bearing housing. At this time, the contact frame on the adjusting tooth plate will not contact the pressing end of the pressing valve, and the pressing valve will not be closed; S5: When the operator controls the adjustment device to make the clutch sleeve contact with the second bevel gear, the transmission gear rotates to drive the rotating gear to rotate, and the rotating gear drives the rotating shaft to make the inner ratchet pawl drive the outer ratchet disc to rotate, and the outer ratchet disc rotates to drive the adjustment tooth plate to move toward the pressing valve, and the movement of the adjustment tooth plate drives the limit bracket to move toward the pressing valve on the bearing shell, and when it moves to the side of the pressing valve, the abutment bracket at the end of the adjustment tooth plate contacts the pressing end of the pressing valve, thereby squeezing the pressing valve, so that the pressing valve is closed to prevent the water pipe from continuing to inject water into the sprinkler head; S6: When the limit bracket is moving, the resistance rod will contact one side of the pressing bracket. After the pressing bracket is deflected, the inclined end will contact the top of the compression type rotating shaft, thereby driving the rotating shaft to move downward. When the rotating shaft moves downward, it will drive the inner ratchet pawl to move downward. At this time, the inner ratchet pawl and the outer ratchet disc are no longer in contact, and the provided pin will limit the rotating shaft after moving downward to prevent the rotating shaft from moving upward and resetting. At this time, when the reset spring on the limit bracket drives the limit bracket to reset, the limit bracket will drive the adjusting tooth plate to move and reset, and the resistance bracket at the end of the adjusting tooth plate will be separated from the pressing end of the pressing valve. The pressing valve will discharge water outward at this time, and when the limit bracket is reset, the resistance rod on the limit bracket The inner and outer ratchet pawls are re-engaged with each other when the rotation of the transmission gear is in progress, so that the inner and outer ratchet pawls are re-engaged with each other, thereby making the transmission gear rotate in a controlled manner and causing the transmission gear to rotate. When the teeth on the semi-bevel gear do not contact the rotating bevel gear and the semi-bevel gear is idling, the rotating shaft is driven by the pressing frame to move downward, and the adjusting tooth plate is moved and reset, so that the pressing valve is in a water-discharging state.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the crops are sprayed in a reciprocating swinging manner by the continuous reciprocating swing of the swinging fertilizing device. This state is suitable for crops with high planting density and close to each other. When the concave end face of the clutch sleeve contacts the conical surface of the second bevel gear, the second bevel gear drives the semi-bevel gear to rotate. When the semi-bevel gear rotates, it drives the rotating bevel gear gap to rotate. The rotating bevel gear gap rotates to rotate the rotating rod gap, thereby causing the swinging fertilizing device to swing intermittently when spraying the crops. This state is suitable for gaps between the planted crops.

[0014] In the present invention, the rotating rod on the swing fertilizing device drives the transmission gear to rotate, and the rotation of the transmission gear drives the rotating gear to rotate, and the rotating gear drives the rotating shaft connected to the shaft to rotate, and the inner ratchet pawl on the rotating shaft contacts the outer ratchet disk, thereby causing the outer ratchet disk to rotate. After the outer ratchet disk contacts the adjusting tooth plate, an articulated frame is hingedly provided between the adjusting tooth plate and the limit bracket, and the two are connected by a spring sheet, so that when the outer ratchet disc rotates and drives the adjusting tooth plate to move, it will cause the adjusting tooth plate to shrink and move in the card cavity on the limit bracket, and the limit bracket will not slide on the bearing shell. At this time, the interference frame on the adjusting tooth plate will not contact the pressing end of the pressing valve, and the pressing valve will not be closed, so that the pressing valve can discharge water normally, so that the spray head can effectively spray medicine.

[0015] In the present invention, the rotation of the transmission gear will drive the rotation of the rotating gear, and the rotating gear will drive the rotating shaft to make the inner ratchet pawl drive the outer ratchet disk to rotate, and the rotation of the outer ratchet disk drives the adjusting tooth plate to move toward the direction of the pressing valve, and the movement of the adjusting tooth plate will drive the limit bracket to move on the supporting shell toward the direction of the pressing valve. When it moves to the side of the pressing valve, the interference bracket at the end of the adjusting tooth plate will contact the pressing end of the pressing valve, thereby squeezing the pressing valve, so that the pressing valve is closed to prevent the water pipe from continuing to inject water into the sprinkler head.

[0016] In the present invention, the pressing end of the pressing valve can be pressed by adjusting the tooth plate to avoid water discharge from the pressing valve, and when the teeth on the semi-bevel gear do not contact the rotating bevel gear and the semi-bevel gear is idling, the rotating shaft is moved downward under the drive of the pressing frame, and the tooth plate is adjusted to move and reset, and the pressing valve is in a state of discharging water. Through this arrangement, when the gap between the crops is large during the swing fertilization of the crops, the water outlet end of the pressing valve is in a closed state and no water discharges when the swing fertilization device swings, and when the swing fertilization device stops swinging, that is, it reaches the crops, the pressing valve is opened at this time to release water. Through this arrangement, the problem of avoiding waste of fertilizers during irrigation and fertilization of crops is effectively solved, and fertilization is carried out after reaching the position of the crops, thereby improving the efficiency of fertilization.

[0024] In this embodiment, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 and Figure 13As shown, the control device 5 includes a limit card holder 51 slidably arranged on the outer wall of the bearing housing 11. A return spring 52 is arranged between the outer wall of the limit card holder 51 and the bearing housing 11. A card cavity 53 is formed inside the limit card holder 51. Fixed rods 54 are fixedly arranged on the limit card holder 51 at equal intervals. An adjusting toothed plate 55 is also arranged in the card cavity 53. Connecting rods 56 are fixedly arranged on the adjusting toothed plate 55 at equal intervals. A hinge frame 57 is hinged between the fixed rod 54 and the connecting rod 56. A spring piece 58 is also sleeved on the fixed rod 54. Two ends of the spring piece 58 are respectively connected to the card cavity 53 of the limit card holder 51 and the adjusting toothed plate 55. A resisting frame 59 is fixedly arranged on the outer wall of the adjusting toothed plate 55. The resisting frame 59 contacts the pressing end of the pressing valve 15. A resisting baffle 510 extends towards the limit card holder 51 from the first limit block 39. The resisting baffle 510 abuts against the limit card holder 51; A transmission gear 6 is also fixedly connected to the rotating rod 27. A rotating gear 61 meshing with the transmission gear 6 is rotatably arranged on the bearing housing 11. A rotating shaft 62 in a compressed state is also rotatably arranged on the bearing housing 11. The rotating shaft 62 is axially connected to the rotating gear 61. An inner ratchet pawl 63 is fixedly arranged on the rotating shaft 62. An outer ratchet disc 64 is rotatably arranged on the bearing housing 11. The inner ratchet pawl 63 abuts against the outer ratchet disc 64. The outer ratchet disc 64 meshes with the adjusting toothed plate 55; A moving groove 65 is also formed on the bearing housing 11. A resisting rod 66 slidably matched with the moving groove 65 is fixedly connected to the limit card holder 51. A pressing frame 67 is rotatably arranged on the bearing housing 11. A resisting spring 68 is arranged between the pressing frame 67 and the bearing housing 11. One side of the pressing frame 67 is inclined. And the inclined end of the pressing frame 67 contacts the top surface of the rotating shaft 62. A retaining pin 69 is also rotatably arranged on the bearing housing 11. An elastic spring 610 is arranged between the retaining pin 69 and the bearing housing 11. One end of the retaining pin 69 abuts against the outer wall of the rotating shaft 62. The end of the retaining pin 69 away from the rotating shaft 62 contacts the resisting rod 66; When the operator controls the adjusting device 3 to make the clutch sleeve 25 contact the first helical gear 23, the first limiting rod 37 on the adjusting frame 31 will drive the first limiting block 39 to move upward. At this time, the contact baffle 510 on the first limiting block 39 will contact the outer wall of the limiting card frame 51, thereby limiting the limiting card frame 51. When the driving and rotating device 2 drives the swinging fertilizing device 4 to swing reciprocally at this time, the rotating rod 27 on the swinging fertilizing device 4 will drive the transmission gear 6 to rotate. The rotation of the transmission gear 6 drives the rotation of the rotating gear 61. The rotating gear 61 drives the rotating shaft 62 connected by the shaft to rotate. The inner ratchet pawl 63 on the rotating shaft 62 contacts the outer ratchet disc 64, thereby causing the outer ratchet disc 64 to rotate. After the outer ratchet disc 64 contacts the adjusting tooth plate 55, since the adjusting tooth plate 55 and the limiting card frame 51 are hinged with a hinge frame 57, and the two are connected by a spring piece 58, when the outer ratchet disc 64 rotates and drives the adjusting tooth plate 55 to move, it will cause the adjusting tooth plate 55 to contract and move in the clamping cavity 53 of the limiting card frame 51, and will not cause the limiting card frame 51 to slide on the bearing housing 11. At this time, the contact frame 59 on the adjusting tooth plate 55 will not contact the pressing end of the pressing valve 15, and will not cause the pressing valve 15 to close. Therefore, the pressing valve 15 can discharge water normally, and the spray head 12 can effectively perform spraying treatment; When the operator controls the adjusting device 3 to make the clutch sleeve 25 contact the second helical gear 24, the first limiting rod 37 on the adjusting frame 31 will drive the first limiting block 39 to move downward. At this time, the contact baffle 510 on the first limiting block 39 no longer contacts the limiting card frame 51. When the driving rod 22 drives the clutch sleeve 25 to rotate, the rotation of the clutch sleeve 25 drives the second helical gear 24 to rotate. When the second helical gear 24 rotates and drives the semi-helical gear 26 to rotate, the rotation of the semi-helical gear 26 will drive the rotating helical gear 28 to rotate. At this time, the rotation of the rotating helical gear 28 will drive the rotating rod 27 to rotate. When the rotating rod 27 rotates and drives the transmission gear 6 to rotate, the rotation of the transmission gear 6 will drive the rotating gear 61 to rotate. The rotating gear 61 will drive the rotating shaft 62 so that the inner ratchet pawl 63 drives the outer ratchet disc 64 to rotate. The rotation of the outer ratchet disc 64 drives the adjusting tooth plate 55 to move in the direction of the pressing valve 15. The movement of the adjusting tooth plate 55 will drive the limiting card frame 51 to move in the direction of the pressing valve 15 on the bearing housing 11. When moving to the side of the pressing valve 15, the contact frame 59 at the end of the adjusting tooth plate 55 will contact the pressing end of the pressing valve 15, thereby squeezing the pressing valve 15 to close and prevent the water pipe 13 from continuing to inject water into the spray head 12; During the movement of the limit card holder 51, the contact rod 66 on the limit card holder 51 will contact one side of the pressing frame 67. After the pressing frame 67 deflects, the inclined end will contact the top of the compression type rotating shaft 62, thereby driving the rotating shaft 62 to move downward. When the rotating shaft 62 moves downward, it will drive the inner ratchet pawl 63 to move downward. At this time, the inner ratchet pawl 63 no longer contacts the outer ratchet disc 64, and the set pin 69 will limit the downward moving rotating shaft 62 to prevent the rotating shaft 62 from moving upward and resetting. When the reset spring 52 on the limit card holder 51 drives the limit card holder 51 to reset, the limit card holder 51 will drive the adjusting tooth plate 55 to move and reset. The contact frame 59 at the end of the adjusting tooth plate 55 will separate from the pressing end of the pressing valve 15, and the pressing valve 15 will discharge water outward at this time. When the limit card holder 51 resets, the contact rod 66 on the limit card holder 51 will contact one end of the pin 69, thereby causing the pin 69 to deflect. After the pin 69 deflects, it no longer contacts the compression end of the rotating shaft 62, and the rotating shaft 62 will move upward and reset at this time. The upward movement and reset of the rotating shaft 62 enables the inner ratchet pawl 63 and the outer ratchet disc 64 to mesh again. Thus, when the transmission gear 6 rotates, it can control the adjusting tooth plate 55 to continue pressing the pressing valve 15. When the teeth on the semi bevel gear 26 contact the rotating bevel gear 28 and drive the transmission gear 6 to rotate, the pressing end of the pressing valve 15 can be pressed through the adjusting tooth plate 55 to prevent the pressing valve 15 from discharging water. When the teeth on the semi bevel gear 26 do not contact the rotating bevel gear 28 and the semi bevel gear 26 idles, the rotating shaft 62 is driven to move downward under the drive of the pressing frame 67. At this time, the adjusting tooth plate 55 moves and resets, and the pressing valve 15 is in the state of discharging water. Through this setting, during the process of swing fertilization of crops, when the gap between crops is relatively large, the water outlet end of the pressing valve 15 is in the closed state and does not discharge water when the swing fertilization device 4 swings. When the swing fertilization device 4 stops swinging, that is, when it reaches the crops, the pressing valve 15 opens at this time and can release water. Through this setting, it effectively solves the problem of fertilizer waste during the irrigation and fertilization of crops, and fertilizes after reaching the position of the crops, improving the fertilization efficiency.

[0025] The usage method and advantages of the present invention: The usage method of the agricultural irrigation and fertilization device is as follows, and the working process is as follows: As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 shown: S1: When the driving rod 22 rotates driven by the driving motor 21, the rotation of the driving rod 22 will drive the clutch sleeve 25 clamped on the driving rod 22 to rotate. When the concave end face of the clutch sleeve 25 contacts the conical surface on the first helical gear 23, the clutch sleeve 25 will drive the first helical gear 23 to rotate. When the first helical gear 23 rotates, the first helical gear 23 will drive the rotating helical gear 28 to rotate. The rotating helical gear 28 drives the rotating rod 27 to continuously rotate, and the rotating rod 27 will drive the swing fertilizing device 4 to continuously swing reciprocally. Through the continuous reciprocal swing of the swing fertilizing device 4, the crops are sprayed reciprocally. When the concave end face of the clutch sleeve 25 contacts the conical surface of the second helical gear 24, the second helical gear 24 will drive the semi-helical gear 26 to rotate. When the semi-helical gear 26 rotates, it will drive the rotating helical gear 28 to rotate intermittently. The intermittent rotation of the rotating helical gear 28 causes the rotating rod 27 to rotate intermittently. Thus, when the swing fertilizing device 4 sprays the crops by swinging, it performs intermittent swinging; S2: The operator makes the adjusting frame 31 deflect towards one side through the swing adjusting frame 31. When the adjusting frame 31 deflects, the deflecting frame 32 will be driven to deflect synchronously under the drive of the tension spring 33 between the adjusting frame 31 and the deflecting frame 32. The deflection of the deflecting frame 32 will drive the two clamping frames 35 arranged by hinge to offset towards one side. The two clamping frames 35 will drive the clutch sleeve 25 to contact the first helical gear 23 or the second helical gear 24, so that the clutch sleeve 25 can be closely attached to the first helical gear 23 or the second helical gear 24, thereby realizing the switching of the friction transmission of the clutch sleeve 25 to the first helical gear 23 and the second helical gear 24; S3: When the rotating rod 27 rotates, the rotating rod 27 will drive the rotating frame 41 to rotate. The positioning rod 42 at the other end of the rotating frame 41 will contact the sliding groove 44 on the swing frame 43 during the rotation process. Thus, the swing frame 43 can be driven by the positioning rod 42 to swing reciprocally on the top of the bearing housing 11. The reciprocating swing of the swing frame 43 drives a plurality of spray heads 12 to be able to spray the crops reciprocally, improving the efficiency of crop irrigation and fertilization; S4: When the operator controls the adjusting device 3 to make the clutch sleeve 25 contact with the first helical gear 23, the first limiting rod 37 on the adjusting frame 31 will drive the first limiting block 39 to move upward. At this time, the contact baffle 510 on the first limiting block 39 will contact the outer wall of the limiting card frame 51, thereby limiting the limiting card frame 51. At this time, when the driving rotation device 2 drives the swing fertilizing device 4 to swing reciprocally, the rotating rod 27 on the swing fertilizing device 4 will drive the transmission gear 6 to rotate. The rotation of the transmission gear 6 drives the rotation gear 61 to rotate. The rotation gear 61 drives the rotating shaft 62 connected by the shaft to rotate. The inner ratchet pawl 63 on the rotating shaft 62 contacts the outer ratchet disc 64, thereby causing the outer ratchet disc 64 to rotate. After the outer ratchet disc 64 contacts the adjusting tooth plate 55, since the adjusting tooth plate 55 and the limiting card frame 51 are hinged with a hinge frame 57 and are connected by a spring piece 58, when the outer ratchet disc 64 rotates to drive the adjusting tooth plate 55 to move, the adjusting tooth plate 55 will contract and move in the clamping cavity 53 of the limiting card frame 51, and the limiting card frame 51 will not slide on the bearing housing 11. At this time, the contact frame 59 on the adjusting tooth plate 55 will not contact the pressing end of the pressing valve 15, and the pressing valve 15 will not be closed; S5: When the operator controls the adjusting device 3 to make the clutch sleeve 25 contact with the second helical gear 24, the rotation of the transmission gear 6 will drive the rotation gear 61 to rotate. The rotation gear 61 will drive the rotating shaft 62 to make the inner ratchet pawl 63 drive the outer ratchet disc 64 to rotate. The rotation of the outer ratchet disc 64 drives the adjusting tooth plate 55 to move towards the pressing valve 15. The movement of the adjusting tooth plate 55 will drive the limiting card frame 51 to move towards the pressing valve 15 on the bearing housing 11. When it moves to the side of the pressing valve 15, the contact frame 59 at the end of the adjusting tooth plate 55 will contact the pressing end of the pressing valve 15, thereby squeezing the pressing valve 15 to close the pressing valve 15 and prevent the water pipe 13 from continuing to inject water into the sprinkler head 12; S6: During the movement of the limit clamping frame 51, the contact rod 66 will contact one side of the pressing frame 67. After the pressing frame 67 deflects, the inclined end will contact the top of the compression type rotating shaft 62, thereby driving the rotating shaft 62 to move downward. When the rotating shaft 62 moves downward, it will drive the inner ratchet pawl 63 to move downward. At this time, the inner ratchet pawl 63 no longer contacts the outer ratchet disc 64, and the provided pin 69 will limit the downward-moved rotating shaft 62 to prevent the rotating shaft 62 from moving upward and resetting. When the reset spring 52 on the limit clamping frame 51 drives the limit clamping frame 51 to reset, the limit clamping frame 51 will drive the adjusting tooth plate 55 to move and reset. The contact frame 59 at the end of the adjusting tooth plate 55 will separate from the pressing end of the pressing valve 15, and the pressing valve 15 will discharge water outward at this time. When the limit clamping frame 51 resets, the contact rod 66 on the limit clamping frame 51 will contact one end of the pin 69, thereby causing the pin 69 to deflect. After the pin 69 deflects, it no longer contacts the compression end of the rotating shaft 62, and the rotating shaft 62 will move upward and reset at this time. The upward reset of the rotating shaft 62 causes the inner ratchet pawl 63 and the outer ratchet disc 64 to mesh again, so that when the transmission gear 6 rotates, it can control the adjusting tooth plate 55 to continue pressing the pressing valve 15. When the teeth on the semi-helical gear 26 contact the rotating helical gear 28 and drive the transmission gear 6 to rotate, the pressing end of the pressing valve 15 can be pressed by the adjusting tooth plate 55 to prevent the pressing valve 15 from discharging water. When the teeth on the semi-helical gear 26 do not contact the rotating helical gear 28 and the semi-helical gear 26 idles, the rotating shaft 62 is driven to move downward under the drive of the pressing frame 67. At this time, the adjusting tooth plate 55 moves and resets, and the pressing valve 15 is in the state of discharging water.
