On the other hand, the water tank sealing can reduce water evaporation in the water tank, which is especially suitable for high-temperature and dry environments, prolongs the water tank water replenishment period, and reduces the water replenishment frequency of the operator.

[0023] The swing moving assembly 3 comprises a driving motor 31, a connecting seat 32, a gear transmission pair 33, a vertical transmission shaft 34, a connecting rod 35, a support frame 36, a top nozzle 37, a connecting flange 38 and side plates 39. The driving motor 31 is fixed on one side of the support frame 36 through the connecting seat 32, the output shaft of the driving motor 31 is rigidly connected with a first gear 331 in the gear transmission pair 33, a second gear 332 in the gear transmission pair 33 is rigidly connected with the lower end of the vertical transmission shaft 34, and the side plates 39 are symmetrically fixed on the two sides of the support frame 36 to form a stable frame support structure for bearing the driving motor 31 and the gear transmission pair 33.

The engagement transmission between the first gear 331 and the second gear 332 has the advantages of high power transmission efficiency, stable operation and no slip phenomenon compared with a belt transmission mode, reduces motor power loss and reduces power consumption. The rotation speed of the vertical transmission shaft 34 can be flexibly adjusted by adjusting the tooth number ratio of the two gears, and the swing frequency of the top nozzle 37 is controlled, the irrigation density requirement of different crops is adapted, and the universality of the equipment is improved.

[0025] The solar energy assembly 4 comprises a solar panel 41, a connecting plate 42 and a battery plate 43, and the solar panel 41 is fixed through the connecting plate 42. The connecting plate 42 plays a role in fixing the solar panel 41, which can ensure that the solar panel 41 is not loose in the outdoor environment such as wind and rain, and ensures long-term stable light collection. The solar panel 41 converts light energy into electrical energy, and the battery plate 43 stores electrical energy, which realizes self-sufficient power supply of the equipment without external power supply or diesel generator. On the one hand, it reduces the energy cost of agricultural irrigation, and on the other hand, it reduces carbon emissions caused by the use of traditional energy, which meets the green agricultural development demand, and is especially suitable for remote farmland without power grid coverage.

[0026] The hinged plate 14 comprises a first hinged plate 40 and a second hinged plate 401; the first hinged plate 40 is hinged to the bottom of the support frame 36, and the second hinged plate 401 is hinged to the top of the support frame 36. The first hinged plate 40 (hinged to the bottom of the support frame 36) and the second hinged plate 401 (hinged to the top of the support frame 36) form a two-point hinged structure, which can more stably adjust the inclination angle of the solar energy assembly 4, and ensure that the solar panel 41 can be perpendicular to the sunlight at different time periods (such as morning, noon and evening), maximize the reception of light, and improve the power generation efficiency. The hinged structure has no rigid friction, the adjustment process is smooth and the component loss is small, which prolongs the service life of the solar energy assembly 4 and reduces the equipment maintenance cost.

[0027] Device positioning and energy and water source reserve: device movement and fixation, the operator pushes the device through the handle 12 in the driving assembly 1, the roller 13 at the bottom of the bottom plate 11 reduces the moving resistance, and the device can be flexibly transported to the target irrigation area. After reaching the position, the device is fixed by using the brake function of the hinged plate 14 and the roller 13, so as to avoid displacement during irrigation.

[0028] The solar panels 41 in the solar assembly 4 are fixed by the connecting plates 42, and the fixed plate 14 of the solar assembly 4 is hinged with the support frame 36 of the swing moving assembly 3 through the hinge plates 14 (including the first hinge plate 40 and the second hinge plate 401), the angles of the first hinge plate 40 (hinged with the bottom of the support frame 36) and the second hinge plate 401 (hinged with the top of the support frame 36) are adjusted, so that the solar panels 41 can maximize the reception of light energy, convert the light energy into electrical energy and store the electrical energy in the solar panels 43 for powering the subsequent electrical components.

[0029] The water tank cover 291 of the water tank 29 in the water supply assembly 2 is opened, and irrigation water is injected into the water tank body 292 through the water inlet 24 located at the center of the water tank 29; after adding water, the water tank cover 291 is closed to prevent impurities from entering. If the water in the water tank body 292 is insufficient during irrigation, the first water pump 21 is started, an external water source is connected through the first water inlet pipe 22, the external water enters the first water pump 21 through the first water inlet pipe 22, and then enters the water tank body 292 through the first water outlet pipe 23, thereby realizing automatic water replenishment.

[0030] The water supply treatment and swing irrigation: the solar panels 43 supply power to the second water pump 25 of the water supply assembly 2, and after the second water pump 25 is started, irrigation water is extracted from the water tank body 292 through the second water inlet pipe 26; after the water flow is pressurized by the second water pump 25, it is delivered to the filter part 28 through the second water outlet pipe 27, the second water outlet pipe 27 is connected with the outer threaded pipe 281 of the filter part 28, the water flow enters the inner threaded filter screen shell 282 on the other side of the outer threaded pipe 281, and the fine filter screen inside the inner threaded filter screen shell 282 filters the sand and impurities in the water to avoid blocking the subsequent components, and the clean water flow continues to be delivered.

[0031] The solar panels 43 simultaneously supply power to the drive motor 31 of the swing moving assembly 3, the drive motor 31 is fixed on one side of the support frame 36 through the connecting seat 32, the output shaft is rigidly connected with the first gear 331 of the gear transmission pair 33, and the first gear 331 is driven to rotate; since the first gear 331 is engaged with the second gear 332, power is transmitted to the second gear 332, and the second gear 332 is rigidly connected with the lower end of the vertical transmission shaft 34, so that the vertical transmission shaft 34 is finally rotated (the side plates 39 on both sides of the support frame 36 are symmetrically fixed to provide stable support for the transmission structure).

[0032] The rotary motion of the vertical transmission shaft 34 is transmitted to the top spray head 37 through the connecting rod 35, and the top spray head 37 is driven to reciprocating swing; at the same time, the clean water flow filtered by the filter part 28 is delivered to the top spray head 37 through the connecting flange 38, and the high-pressure water flow is sprayed from the top spray head 37, which realizes uniform irrigation in the horizontal range in combination with the swing motion.

[0033] Dynamic replenishment and parameter adjustment: in irrigation, the water level in the water tank body 292 decreases in real time, and when the water level is lower than the threshold (implicit design), the first water pump 21 is automatically started, and the water replenishment process of the external water source, the first water inlet pipe 22, the first water pump 21, the first water outlet pipe 23 and the water tank body 292 is repeated until the water level returns to normal and the first water pump 21 stops, ensuring continuous irrigation.

[0034] Under light conditions, the solar panel 41 continuously generates electricity and stores electricity in the battery panel 43; if it is cloudy and the light is insufficient, the stored electrical energy of the battery panel 43 can maintain the operation of the second water pump 25 and the driving motor 31 for a short time, avoiding interruption of irrigation.

[0035] By adjusting the speed of the driving motor 31, the transmission ratio of the gear transmission pair 33 (the first gear 331 and the second gear 332) is changed, and the rotation speed of the vertical transmission shaft 34 is adjusted, and finally the swing frequency of the top nozzle 37 is changed, which adapts to the irrigation density requirements of different crops.

[0036] Device shutdown and reset: after completing irrigation, turn off the device main switch, stop the driving motor 31, the first water pump 21 and the second water pump 25, and the top nozzle 37 stops spraying and resets to the initial position. The operator pushes the device through the handle 12, and uses the roller 13 to transfer the device to the next area or storage point, and completes the entire operation process.

[0037] Therefore, the small agricultural mechanical irrigation device adopts the above-mentioned swing moving assembly, which is driven by the driving motor to swing the top nozzle, greatly improving the irrigation coverage and uniformity, and the filter part of the water supply assembly can filter impurities in the irrigation water, avoiding clogging of the top nozzle to ensure the stability of irrigation.

[0038] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application and not to limit them, although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that: it can still modify or equivalently replace the technical solutions of the present application, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present application.
