As shown in fig. 2 to 13, the following steps:

As can be seen with particular reference to fig. 11 and 12, the peristaltic pump 1 comprises a fixedly mounted cylindrical housing 11 and a rotatable rotor 13. An inner hose 12 is arranged on the circumferential inner wall of the shell 11, and both ends of the inner hose 12 are respectively connected with a feeding pipe communicated with the corresponding positive pressure feeding cavity and a discharging pipe communicated with the spray head 30; the rotor 13 is coaxially assembled with the housing 11 and is provided with at least three protrusions capable of squeezing the inner hose 12 at equal intervals in the circumferential direction of the rotor 13. As can be seen, the outer convex part is preferably a pressing roller which is rotatably mounted on the rotor 13, so that the outer convex part can smoothly revolve to press the inner hose 12 when the rotor 13 rotates, and friction generated when the outer convex part presses the inner hose 12 can be reduced based on the rotation of the outer convex part, and the abrasion of the inner hose 12 is further reduced.
One feeding part of the feeding assembly 10 for realizing the intermittent feeding of the fertilizer comprises a driving ring 2, a discharging sleeve 4 and a feeding sleeve 6 which are coaxially sleeved on a guide column 3. Wherein the driving ring 2 rotates synchronously with the peristaltic pump 1, and a feeding station and a discharging station are arranged along the rotating path of the driving ring 2.
Specifically, the method comprises the following steps:
a limit push rod 21 is rotatably arranged at one end of the drive ring 2, a return spring is connected between a rotating shaft of the limit push rod 21 and the drive ring 2, one end of the limit push rod 21 limited by the return spring can be abutted against the outer surface wall of the guide post 3, and the other end can extend to the outside of the discharge sleeve 4;
the diameter of the guide column 3 is smaller than the inner diameter of the driving ring 2, and a plurality of convex one-way ratchets 31 are arranged on the circumferential outer wall of the guide column 3; in addition, a material guiding transition cavity 32 communicated with the corresponding positive pressure feeding cavity is formed inside the material guiding column 3, a first material outlet 33 is formed at one side of the material guiding transition cavity 32, and a first material inlet 34 is formed at one end of the material guiding transition cavity 32;
the outer diameter of the discharge sleeve 4 is larger than that of the drive ring 2, a stop lever 41 is axially fixed at one end of the discharge sleeve 4, and the stop lever 41 is positioned outside the drive ring 2; the inner diameter of the discharging sleeve 4 is equal to the diameter of the guide column 3, and a second discharging hole 42 is formed in the discharging sleeve 4;
the feeding sleeve 6 is fixedly arranged, and a second feeding hole 61 is formed in the feeding sleeve 6; in addition, the inner diameter of the feeding sleeve 6 is equal to the diameter of the guide post 3, and a volute spring is connected between the feeding sleeve 6 and the guide post 3.
In summary, in combination with the principles shown in fig. 4-7, the material guiding column 3 can swing back and forth between the feeding station and the discharging station in the process of the continuous rotation of the driving ring 2 by the cooperation of the spiral spring, the one-way ratchet 31, the limit push rod 21 and the stop rod 41, specifically: when the guide column 3 swings to the discharging station, the first discharging port 33 is communicated with the second discharging port 42, and when the guide column 3 swings back to the feeding station, the first feeding port 34 is communicated with the second feeding port 61.
In the schematic diagrams shown in fig. 4-7, a is a state diagram of the one-way ratchet 31, the limit push rod 21 and the stop lever 41, b is a state diagram of the guide column 3 and the feeding sleeve 6, c is a schematic diagram of the guide column 3 and the discharging sleeve 4, and the states shown in the three diagrams a-b-c correspond to each other. Specifically, the method comprises the following steps:
in fig. 4, the limit push rod 21 rotates clockwise with the driving ring 2 to a state of meshing with the one-way ratchet 31, in which the driving ring 2 is not pushed, and correspondingly the guide pillar 3 is limited by the spiral spring to be in a discharging station, namely, a state that the first feed opening 34 is communicated with the second feed opening 61 as shown in fig. 4 b;
in fig. 5, the limit push rod 21 continues to rotate clockwise along with the driving ring 2, at this time, the limit push rod 21 pushes the one-way ratchet 31, so that the guide pillar 3 rotates clockwise along with the driving ring 2 synchronously until the guide pillar rotates to the discharging position shown in fig. 5, and correspondingly, in fig. 5c, the first discharging hole 33 is communicated with the second discharging hole 42. In the position shown in fig. 5, the driving ring 2 continues to rotate clockwise, and at this time, the limit push rod 21 is blocked by the blocking rod 41, so that the blocking rod 41 generates counterclockwise rotation itself, and under the action of the rotation, one end of the blocking rod 41 contacting the one-way ratchet 31 is gradually raised outwards, i.e. the blocking rod 41 and the one-way ratchet 31 are gradually separated, and the first discharge hole 33 is still communicated with the second discharge hole 42 in the changing process, so that the size of the second discharge hole 42 is set to be larger than that of the first discharge hole 33. In addition, the spiral spring is deformed to accumulate force in the whole process.
In fig. 6, the limit push rod 21 is shown in a critical state of engaging with the one-way ratchet 31, and in this state, if the drive ring 2 continues to rotate clockwise, the limit push rod 21 is completely disengaged from the one-way ratchet 31. Once the limit push rod 21 is separated from the one-way ratchet 31, the space between the guide pillar 3 and the driving ring 2 is not limited, and the guide pillar 3 is driven to swing back to the discharging station shown in fig. 4 under the resilience of the spiral spring. After the limit push rod 21 is completely separated from the one-way ratchet 31, the drive ring 2 continues to rotate clockwise so that the limit push rod 21 can be separated from the stop lever 41, and after the limit push rod 21 can be separated from the stop lever 41, the stop lever 41 can be rotated and reset under the resilience of the reset spring.
In fig. 7, that is, a state is shown in which the stop lever 41 is again engaged with the one-way ratchet 31 after being returned to the original position, in this state, the drive ring 2 continues to rotate clockwise in the position shown in fig. 7, and the swing of the guide pillar 3 is performed again according to the same change principle as shown in fig. 4, 5 and 6, and the guide pillar 3 performs the feeding and discharging of the fertilizer only when it is located at the discharging station shown in fig. 5 and 6, thereby effectively realizing the intermittent fertilization based on the above principle.
Preferably, in order to realize the linkage between the two feeding portions, as shown in fig. 11 and 13 (for convenience of illustration, only one-way ratchet 31 is shown in fig. 13), a specific embodiment is provided in the present invention:
one end of the rotor 13 is provided with a telescopic rod 16 coaxially assembled with the rotor 13, and the telescopic rod 16 can synchronously rotate along with the rotor 13;
the telescopic rod 16 is sleeved with a driving wheel 17, and the driving wheel 17 is in transmission fit with the driving ring 2 so that the driving ring 2 rotates synchronously with the driving wheel 17.
Specifically, as for the transmission fit between the transmission wheel 17 and the driving ring 2, a belt, a chain, a gear or the like can be used for transmission, and fig. 13 only shows the transmission manner of the belt, so as to effectively realize the linkage between the two feeding portions of the feeding assembly 10. In addition, as for the driving rotation of the rotor 13, one of them can be driven by a motor, and the other can be driven by connecting a transmission belt between the wheels of the walking trolley and the rotating shaft of the rotor 13.
Specifically, as for the driving manner of the second driving manner, it can be known from the principle of fig. 8 that only one-way driving is formed between the material guiding column 3 and the driving ring 2 by using the cooperation of the one-way ratchet 31 and the limit push rod 21, so that the whole device is ensured to perform fertilization and irrigation operations only when the walking trolley moves forward, the whole peristaltic pump 1 and the driving ring 2 are driven reversely when the walking trolley moves backward, and at this time, no water and/or fertilizer is led out from the spray head 30, thereby effectively avoiding the problem of repeated fertigation when the whole device moves backward.

With respect to the peristaltic pump 1 described above, a preferred embodiment is provided in the present invention as follows:
the two ends of the rotor 13 are respectively rotatably connected with a limiting column 14 and a limiting frame 15, the limiting column 14 and the limiting frame 15 are respectively in sliding fit with the inside and the outside of the shell 11 along the axial direction, the diameter of the limiting column 14 is not smaller than the outer diameter of the rotor 13, and the conduction sectional area of the inner hose 12 can be limited through the axial sliding adjustment of the limiting column 14.
In this embodiment, as can be seen from fig. 11, the inner hose 12 is attached to the inner wall of the housing 11 along the axial direction, and the axial width of the inner hose is not greater than the axial length of the housing 11, when one end of the limiting column 14 slides towards the inside of the housing 11, the outer wall of the limiting column 14 presses the inner hose 12, so that part of the inner hose 12 is limited between the outer wall of the limiting column 14 and the inner wall of the housing 11, and correspondingly, because the diameter of the limiting column 14 is not smaller than the outer diameter of the rotor 13, the part of the inner hose 12 pressed by the limiting column 14 cannot perform water guiding, thereby effectively changing the conduction cross-sectional area of the inner hose 12.
Specifically, when the cross-sectional area of the inner tube 12 decreases, the amount of water delivered per unit time decreases, whereas when the cross-sectional area of the inner tube 12 increases, the amount of water delivered per unit time increases, and the irrigation water amount of the entire device is flexibly adjusted based on this.
In addition, based on the cooperation of spacing post 14 and spacing frame 15, can guarantee that rotor 13 is located one side of spacing post 14 all the time, and then make rotor 13 correspond with the partial interior hose 12 that keeps conducting on all the time, then can effectively carry out the continuous ejection of compact irrigation of water along with rotor 13 of rotor continuously rotates.
As can be seen from the above, in the present embodiment, when the conduction cross-sectional area of the inner hose 12 is adjusted, the entire rotor 13 needs to move along the axial direction, and the telescopic rod 16 is correspondingly set to include an inner rod and an outer rod which can slide relatively in the axial direction, wherein the inner rod is connected with the rotor 13, and the outer rod is connected with the driving wheel 17, so that the movement of the rotor 13 and the transmission of the driving wheel 17 can be effectively ensured without interfering with each other.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
