Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, the invention provides an irrigation and fertilization device for planting kiwi fruits, which comprises a feeding assembly 10, a feeding box 20 and a spray head 30, wherein the feeding assembly 10, the feeding box 20 and the spray head 30 are arranged on a travelling trolley.
Specifically, as shown in fig. 14, two non-interfering positive pressure feed chambers are formed in the feed tank 20, and the two positive pressure feed chambers are used for storing water and fertilizer, respectively. Based on the structure shown in the figure, the two positive pressure feeding cavities are matched with the pushing plate through the extrusion springs to form positive pressure feeding, so that the feeding box 20 is ensured to have positive pressure power for continuously feeding outwards.
Further, a feeding pipeline is connected between the feeding box 20 and the spray head 30, and the feeding assembly 10 is arranged on the feeding pipeline; the feeding assembly 10 comprises two feeding parts, and the two feeding parts are linked to realize continuous feeding of water and intermittent feeding of fertilizer.
From the above, the device in the invention realizes mobile fertigation by using the walking trolley, and performs continuous feeding of water and intermittent feeding of fertilizer by using two feeding parts of the feeding assembly in the moving process, wherein:
the continuous feeding of water effectively realizes continuous irrigation of the kiwi fruits in the walking process of the integral device, and particularly, the continuous irrigation mode is selected, so that the water quantity required in the growth process of the kiwi fruits is ensured, and meanwhile, the problem that a large amount of water is irrigated around the root of the kiwi fruits in a concentrated manner to cause root rot is avoided;

In addition, water and fertilizer are led out by adopting the same spray head 30, so that the fertilizer can be smoothly discharged under the impact of water flow, and the problem of blockage of the spray head 30 is effectively avoided.
As shown in connection with fig. 2-13, the above is described:
one feeding section of the feeding assembly 10 that achieves continuous feeding of water comprises a peristaltic pump 1. Referring specifically to fig. 11 and 12, peristaltic pump 1 includes 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 two ends of the inner hose 12 are respectively connected with a feed pipe communicated with a corresponding positive pressure feed cavity and a discharge pipe communicated with the spray head 30; the rotor 13 is coaxially assembled with the housing 11, and at least three male protrusions capable of pressing the inner hose 12 are provided equidistant along the circumferential direction of the rotor 13. As can be seen from the figure, the outer protruding member is preferably a pressing roller rotatably mounted on the rotor 13, so that the outer protruding member can smoothly revolve to press the inner hose 12 when the rotor 13 rotates, and friction when the outer protruding member presses the inner hose 12 can be reduced based on rotation of the outer protruding member, thereby reducing abrasion of the inner hose 12.
One feeding part of the feeding assembly 10 for realizing intermittent feeding of fertilizer comprises a driving ring 2, a discharging sleeve 4 and a feeding sleeve 6 which are coaxially sleeved on a material guiding column 3. Wherein the driving ring 2 synchronously rotates along with the driving of the peristaltic pump 1, and a feeding station and a discharging station are arranged along the rotating path of the driving ring 2.
Specific:
a limiting push rod 21 is rotatably arranged at one end of the driving ring 2, a reset spring is connected between the rotating shaft of the limiting push rod 21 and the driving ring 2, one end of the limiting push rod 21 is limited by the reset spring to be capable of abutting against the outer surface wall of the material guiding column 3, and the other end of the limiting push rod can extend to the outside of the material discharging sleeve 4;
the diameter of the material guiding 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 material guiding column 3; in addition, a guide transition cavity 32 communicated with the corresponding positive pressure feed cavity is formed inside the guide column 3, a first discharge port 33 is formed at one side of the guide transition cavity 32, and a first feed port 34 is formed at one end of the guide transition cavity 32;
the outer diameter of the discharging sleeve 4 is larger than that of the driving ring 2, a stop lever 41 is axially fixed at one end of the discharging sleeve 4, and the stop lever 41 is positioned at the outer side of the driving ring 2; the inner diameter of the discharging sleeve 4 is equal to the diameter of the material guiding 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 column 3, and a spiral spring is connected between the feeding sleeve 6 and the guide column 3.
In summary, and in combination with the principles shown in fig. 4 to fig. 7, it can be known that, by matching the spiral spring, the unidirectional ratchet 31, the limiting push rod 21 and the stop lever 41, the guide post 3 can swing reciprocally between the feeding station and the discharging station in the continuous rotation process of the driving ring 2, specifically: the first discharge port 33 is communicated with the second discharge port 42 when the guide column 3 swings to the discharge station, and the first feed port 34 is communicated with the second feed port 61 when the guide column 3 swings back to the feed station.
In the schematic diagrams shown in fig. 4 to 7, a is a state diagram of the unidirectional ratchet 31 and the limit push rod 21 matched with the stop lever 41, b is a state diagram of the guide column 3 matched with the feeding sleeve 6, c is a schematic diagram of the guide column 3 matched with the discharging sleeve 4, and the states shown in the three diagrams a-b-c correspond to each other. Specific:
in fig. 4, the limit push rod 21 rotates clockwise with the driving ring 2 to a state of meshing with the unidirectional ratchet 31, in which the driving ring 2 is not pushed, and the corresponding guide column 3 is defined by the spiral spring to be in a discharge station, i.e., a state in which the first feed port 34 and the second feed port 61 shown in fig. 4b are communicated;
in fig. 5, the limiting push rod 21 continues to rotate clockwise along with the driving ring 2, at this time, the limiting push rod 21 pushes the unidirectional ratchet 31, so that the guide post 3 rotates clockwise along with the driving ring 2 synchronously until rotating to the discharging position shown in fig. 5, and correspondingly, in fig. 5c, the first discharging port 33 is communicated with the second discharging port 42. In the position shown in fig. 5, the driving ring 2 continues to rotate clockwise, at this time, the stop rod 21 is blocked by the stop rod 41, so that the stop rod 41 rotates counterclockwise, under the action of the rotation, one end of the stop rod 41 contacting the unidirectional ratchet 31 gradually and outwards, that is, the stop rod 41 and the unidirectional ratchet 31 are gradually separated, and in the process of the change, the first discharge port 33 is still communicated with the second discharge port 42, so that the size of the second discharge port 42 is set to be larger than that of the first discharge port 33. In addition, the wrap spring deforms during the overall process to store force.
In fig. 6, a critical state is shown in which the stopper push rod 21 is engaged with the one-way ratchet 31, and in this state, if the drive ring 2 continues to rotate clockwise, the stopper push rod 21 is completely disengaged from the one-way ratchet 31. Once the limit push rod 21 is separated from the unidirectional ratchet 31, the limit between the material guiding column 3 and the driving ring 2 is lost, and the material guiding column 3 is driven to swing back to the discharging station shown in fig. 4 under the rebound of the spiral spring. After the limit push rod 21 is completely separated from the unidirectional ratchet 31, the driving 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 in which the bar 41 is rotated and reset and then is engaged with the unidirectional ratchet 31 again, in which the driving ring 2 continues to rotate clockwise along the position shown in fig. 7, and the swing of the guide post 3 is again performed according to the same variation principle as shown in fig. 4, 5 and 6, and the guide post 3 performs the guiding and feeding of the fertilizer only when it is located at the discharging station shown in fig. 5 and 6, whereby intermittent fertilization can be effectively realized based on the above principle.
Preferably, in order to achieve the linkage between the two feeding portions, as shown in fig. 11 and 13 (only one unidirectional ratchet 31 is shown in fig. 13 for convenience of illustration), a specific embodiment is provided in the present invention:
a telescopic rod 16 coaxially assembled with the rotor 13 is arranged at one end of the rotor 13, and the telescopic rod 16 can synchronously rotate along with the rotor 13;
a driving wheel 17 is sleeved on the telescopic rod 16, and the driving wheel 17 is in driving fit with the driving ring 2 so as to enable the driving ring 2 to synchronously rotate along with the driving wheel 17.
Specifically, regarding the transmission cooperation between the transmission wheel 17 and the driving ring 2, transmission can be performed by adopting a belt, a chain or a gear, etc., and only the transmission mode of the belt is shown in fig. 13, so that linkage between two feeding parts of the feeding assembly 10 is effectively realized. In addition, regarding the driving rotation of the rotor 13 itself, one may perform driving by using a motor, and the other may also perform driving by connecting a transmission belt between the wheels of the traveling carriage and the rotation shaft of the rotor 13.
Specifically, as for the driving mode of the second embodiment, as can be seen by correspondingly combining the principle of fig. 8, only one-way driving is formed by utilizing the cooperation of the one-way ratchet 31 and the limiting push rod 21 between the material guiding column 3 and the driving ring 2, so that the whole device is ensured to execute fertilization and irrigation operations only when the travelling trolley moves forward, and the whole peristaltic pump 1 and the driving ring 2 are reversely driven when the travelling trolley moves backward, no water and/or fertilizer is led out from the spray head 30 at this time, and the problem of repeated irrigation and fertilization when the whole device moves backward is effectively avoided.

From the above, the specific adjustment operation for the rotation of the discharge sleeve 4 is as follows: the limiting sleeve 43 is pulled to be far away from the material guiding sleeve 5, the positioning spring is stretched at the moment, the limiting sleeve 43 and the material discharging sleeve 4 are in a rotatable state, and the limiting sleeve 43 is rotated to drive the material discharging sleeve 4 to rotate and adjust.

the threaded rod is rotated, and the length of the threaded rod extending into the guide transition cavity 32 is adjusted by utilizing the spiral transmission between the threaded rod and the guide column 3, so that the positioning position of the limiting piston 36 is changed. When the limiting piston 36 moves in the direction of the material guiding cavity, the axial length of the material guiding cavity is reduced, and the corresponding fertilizer amount temporarily stored in the material guiding cavity is reduced; when the limit piston 36 moves towards the direction of the driving cavity, the axial length of the material guiding cavity is increased, and the corresponding amount of fertilizer temporarily stored in the material guiding cavity is increased.
When the guide column 3 is positioned at the feeding station, the fertilizer can smoothly enter the guide cavity of the guide transition cavity 32 by utilizing the communication between the second feed port 61 and the first feed port 34, and the discharge piston 35 is pushed to extrude the elastic piece.
When the material guiding column 3 swings from the feeding station to the discharging station, the first feeding hole 34 and the first discharging hole 33 are only kept sealed due to the limitation of the feeding sleeve 6 and the discharging sleeve 4, so that the fertilizer can be temporarily stored in the material guiding cavity of the material guiding transition cavity 32.
When the material guiding column 3 is positioned at the material discharging station, the material guiding cavity of the material guiding transition cavity 32 is in an open state by utilizing the communication between the first material discharging hole 33 and the second material discharging hole 42, and the material discharging piston 35 is driven to approach the first material discharging hole 33 based on the rebound of the elastic piece in the state, so that the fertilizer temporarily stored in the material guiding cavity is guided out to the spray head 30 through the first material discharging hole 33 and the second material discharging hole 42.
In addition, in the present invention, regarding the arrangement of the stopper and the elastic member, the stopper may be further arranged between the discharging piston 35 and the stopper piston 36, and in this case, the stopper may be preferably an electric telescopic rod, and the elastic member is preferably a compression spring.
Third preferred embodiment
With respect to the peristaltic pump 1 described above, in the present invention there is provided a preferred embodiment as follows:
the two ends of the rotor 13 are respectively connected with a limiting column 14 and a limiting frame 15 in a rotating way, and the limiting column 14 and the limiting frame 15 are respectively matched with the inside and the outside of the shell 11 in a sliding way along the axial direction, wherein 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 by 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 12 does not exceed the axial length of the housing 11, when one end of the limiting post 14 slides towards the inside of the housing 11, the outer wall of the limiting post 14 presses the inner hose 12, so that a part of the inner hose 12 is limited between the outer wall of the limiting post 14 and the inner wall of the housing 11, and correspondingly, the diameter of the limiting post 14 is not smaller than the outer diameter of the rotor 13, so that the part of the inner hose 12 pressed by the limiting post 14 cannot conduct water, thereby effectively changing the conducting cross-sectional area of the inner hose 12.
Specifically, when the conduction cross-sectional area of the inner tube 12 is reduced, the amount of water to be introduced per unit time is reduced, whereas when the conduction cross-sectional area of the inner tube 12 is increased, the amount of water to be introduced per unit time is increased, and the amount of irrigation water of the entire device is flexibly adjusted based on this.
In addition, based on the cooperation of the spacing post 14 and the spacing 15, the rotor 13 can be ensured to be positioned at one side of the spacing post 14 all the time, and then the rotor 13 can be always corresponding to the part of the inner hose 12 which is kept on, and continuous discharging irrigation of water can be effectively executed along with continuous rotation of the rotor 13 of the rotor.
As can be seen from the above, in the present embodiment, when the conductive cross-sectional area of the inner hose 12 is adjusted, the integral rotor 13 needs to move along the axial direction, and the corresponding telescopic rod 16 is set to include an inner rod and an outer rod capable of sliding relatively along 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 no interference between the movement of the rotor 13 and the driving of the driving wheel 17 can be effectively ensured.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
