In addition, traditional equipment often requires a large space, complicated operation process and frequent maintenance.

[0004] At present, some advanced agricultural equipment has begun to try to integrate multiple functions such as spraying, insect control, irrigation, and fertilization in one, with the aim of improving work efficiency, reducing resource waste, and reducing negative impacts on the environment. Although there are some technical solutions that can achieve automated spraying and irrigation, it is still technically difficult to achieve precise insect control, fertilization, and irrigation in the same system at the same time, and to ensure that each functional module can work in coordination during different operations.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0041] See also Figure 1 , Fig.13 An integrated insect prevention, irrigation and fertilization equipment based on vegetable greenhouse cultivation includes a traveling frame 1, a lifting mechanism 2, a tilt adjustment mechanism 3, and an operating mechanism 4. The lifting mechanism 2 is assembled on the traveling frame 1, and the tilt adjustment mechanism 3 is assembled to the movable part of the lifting mechanism 2 and realizes lifting and lowering movement with the lifting mechanism 2.

[0042] The operating mechanism 4 includes an assembly bracket 41, a main retractable bracket 42, an auxiliary retractable bracket 43, an alignment adjustment component 44, a retractable adjustment component 45, a spraying component 46 and a driving component 47. The assembly bracket 41 is matched with the inclination adjustment mechanism 3 and realizes flipping movement with the inclination adjustment mechanism 3. The main retractable bracket 42 is slidably installed on the assembly bracket 41. The alignment adjustment component 44 is installed on the assembly bracket 41 and maintains power connection with the main retractable bracket 42. The auxiliary retractable bracket 43 includes two groups that are slidably installed on the main retractable bracket 42 and are symmetrically arranged. The retractable adjustment component 45 maintains power connection with the two groups of auxiliary retractable brackets 43. The driving component 47 is installed on the assembly bracket 41 and maintains power connection with the alignment adjustment component 44 and the retractable adjustment component 45.

[0043] The spray assembly 46 includes a nozzle 461, a liquid supply pipe 462 and a scissor-type mechanism 463. The scissor-type mechanism 463 is assembled to the main retractable bracket 42 and the auxiliary retractable bracket 43. The liquid supply pipe 462 is evenly assembled on the scissor-type mechanism 463. The nozzle 461 is connected to the bottom of the liquid supply pipe 462 and extends to the bottom of the main retractable bracket 42.

[0044] The traveling frame 1 runs along the length direction of the vegetable greenhouse, and drives the lifting mechanism 2, the tilt adjustment mechanism 3, and the operating mechanism 4 directly or indirectly installed thereon to move stably along the length direction of the vegetable greenhouse, and then uses the operating mechanism 4 to realize the planting operations of insect prevention, irrigation, and fertilization of the planted vegetables.

[0045] When operating, the driving component 47 is controlled to operate to drive the retractable and extendable component 45 to operate, so as to drive the two sets of auxiliary retractable and extendable brackets 43 to operate in opposite directions and extend from the end along the length direction of the main retractable and extendable bracket 42, so that the operating mechanism 4 is in an open posture, and then with the help of the cooperation between the main retractable and extendable bracket 42 and the auxiliary retractable and extendable bracket 43, the overall length of the scissor-type mechanism 463 is synchronously extended, so that the liquid supply pipe 462 and the connected nozzle 461 are always evenly distributed on the scissor-type mechanism 463.

[0046] When the auxiliary retractable bracket 43 is in a fully open position on the main retractable bracket 42, the overall length of the operating mechanism 4 is slightly smaller than the width of the vegetable planting greenhouse, thereby ensuring that the operating mechanism 4 can move stably therein and avoid spatial movement interference with the vegetable greenhouse. At this time, the spacing of the nozzles 461 remains comparable to the vegetable planting spacing.

[0047] The driving component 47 drives the alignment adjustment component 44 to drive the column retractable bracket and the components assembled thereon to slide along the width direction of the vegetable greenhouse (the length direction of the main retractable bracket 42) so that each nozzle 461 remains relative to the vegetables planted below or the soil between the vegetables.

[0048] When the planted vegetables are subjected to insect control, the nozzle 461 can be positioned opposite to the vegetables through the alignment adjustment component 44, and the liquid containing insecticide sprayed by the nozzle 461 can evenly cover the vegetables, thereby achieving the purpose of killing insects. When the planted vegetables are irrigated or fertilized, the nozzle 461 can be positioned opposite to the soil between the vegetables through the alignment adjustment component 44, and the clean water or liquid containing liquid fertilizer sprayed by the nozzle 461 can fall into the soil and quickly penetrate into the soil, so as to supply water and fertilizer to the root system of the planted vegetables.

[0049] Nozzle 461 adopts a common electrically controlled product on the market, which can adjust the switch and water spraying state of nozzle 461. When the integrated equipment is assembled, each liquid supply pipe 462 is connected to the liquid supply main pipe to supply corresponding liquid to each nozzle 461. When spraying the insecticide liquid, the water spraying state of nozzle 461 is adjusted to mist, so that the sprayed insecticide is atomized and can be evenly attached to the vegetables. When spraying water or liquid fertilizer, the water spraying state of nozzle 461 is adjusted to water column, so that the water or liquid fertilizer can fall accurately into the soil.

[0050] The inclination adjustment mechanism 3 can drive the operating mechanism 4 to flip its angle as a whole. The rotation axis of the operating mechanism 4 is parallel to the width direction of the vegetable greenhouse, so as to realize synchronous adjustment of the inclination angle of each nozzle 461, so that the angle of spraying liquid is at a specific angle with the horizontal ground, thereby increasing the spraying area and range of the liquid.

[0051] The lifting mechanism 2 can drive the overall lifting movement of the operating mechanism 4 to adjust the distance between the nozzle 461 and the vegetables or the ground, thereby achieving a coordinated adjustment of the spraying range and accuracy of the liquid. Example

[0052] See See Figure 1-Figure 2 In order to ensure that the traveling frame 1 can be stably assembled on the top of the vegetable greenhouse and achieve stable movement along the length direction of the vegetable greenhouse, the following technical solution is provided.

[0053] Two sets of parallel travel rails 11 are set up on the top of the vegetable greenhouse. Travel wheels 12 mounted on the travel rails 11 are rotatably installed on both sides of the travel frame 1. Capstans 13 are installed at both ends of the travel rails 11. Steel wire ropes 14 are wound around the capstans 13. Both ends of the steel wire ropes 14 are fixedly connected to the two ends of the travel frame 1.

[0054] The setting of the travel guide rail 11 can ensure that the traveling frame 1 is stably assembled thereon, and cooperate with the travel wheel 12 to enable the traveling frame 1 to stably move along the length direction on the top of the vegetable greenhouse, thereby driving the operating mechanism 4 to move synchronously.

[0055] Both ends of the wire rope 14 are respectively passed around the winch 13 on the corresponding side and fixedly connected to the connecting piece 15 provided on the traveling frame 1. When driving one group of winches 13 to operate, the traveling frame 1 can be pulled by the wire rope 14 to stably move along the traveling guide rail 11. Example

[0056] See See Figure 3-Figure 5 In order to ensure that the lifting mechanism 2 can be stably assembled on the traveling frame 1 and realize stable lifting in the vertical direction, the following technical solution is provided.

[0057] The lifting mechanism 2 includes a fixed bracket 21, a lifting bracket 22, an adjusting screw 23, a reduction motor 24, and a driving shaft 25. The fixed bracket 21 includes two groups fixedly installed on the traveling frame 1 and symmetrically arranged. The lifting bracket 22 is slidably installed in each group of fixed brackets 21. The lifting bracket 22 passes through the lower surface of the traveling frame 1 and moves up and down in the vertical direction. The adjusting screw 23 that is rotated to maintain a rotation connection with the lifting bracket 22 is rotatably installed in each group of fixed brackets 21. The reduction motor 24 is fixedly installed on the traveling frame 1, and the driving shaft 25 is rotatably installed on the traveling frame 1 and is connected to the reduction motor 24 in power.

[0058] Both ends of the driving shaft 25 are fixedly connected with driving bevel gears A251, and both sets of adjusting screws 23 are fixedly connected with transmission bevel gears A231 respectively meshing with the two sets of driving bevel gears A251.

[0059] The setting of the fixed bracket 21 can ensure that the adjusting screw 23 is stably installed thereon in a relatively rotating manner, and ensure that the lifting bracket 22 is slidably installed thereon. When the reduction motor 24 is working, it can drive the two sets of driving bevel gears A251 to operate synchronously through the driving shaft 25, and then drive the transmission bevel gear A231 and the adjusting screw 23 to operate stably, so as to drive the two sets of lifting brackets 22 to ensure synchronous lifting movement, so that the inclination adjustment mechanism 3 and the operating mechanism 4 can stably lift and lower in the vertical direction.

[0060] In order to ensure that the inclination angle adjustment mechanism 3 can be stably assembled on the lifting mechanism 2 and realize effective adjustment of the inclination angle of the working mechanism 4, the following technical solution is provided.

[0061] The inclination adjustment mechanism 3 includes a connecting bracket 31, an adjusting motor 32, and a worm wheel A33 and a worm A34 that maintain a matching combination. The connecting bracket 31 is fixedly connected to the bottom ends of the two groups of lifting brackets 22. Both ends of the assembly bracket 41 are fixedly connected with assembly shafts 411 that maintain a coaxial arrangement. The assembly shaft 411 is rotatably installed in the connecting bracket 31. The worm wheel A33 is fixed to the axis center of one group of assembly shafts 411. The adjusting motor 32 is fixedly installed on the connecting bracket 31. The worm A34 is rotatably installed on the connecting bracket 31 and is fixedly connected to the output shaft of the adjusting motor 32.

[0062] The connecting bracket 31 is fixedly connected to the lifting bracket 22 in the lifting assembly, and can drive the inclination adjustment mechanism 3 to rise and fall synchronously when the lifting assembly is lifted and lowered. The assembly axis 411 provided on the assembly bracket 41 is rotated in combination with the connecting bracket 31, so that the assembly bracket 41 can rotate around the assembly axis 411 on the connecting bracket 31.

[0063] When the adjusting motor 32 drives the worm A34 to operate, it can drive the worm wheel A33 and the assembly shaft 411 to operate stably, and then drive the assembly bracket 41 to operate stably, so as to adjust the overall inclination angle of the operating mechanism 4.

[0064] The combination of the worm wheel A33 and the worm A34 has the characteristics of speed reduction and torque increase and one-way self-locking, that is, when the power of the worm A34 is transmitted to the worm wheel A33, the rotation speed can be reduced and the torque can be increased to drive the assembly bracket 41 and the components installed on the assembly bracket 41 to operate stably. When the inclination adjustment is completed and the adjustment motor 32 stops, the worm wheel A33 is locked by the worm A34, so that the operating mechanism 4 can stabilize the position of a specific inclination posture. Example

[0065] See See Figure 6-Figure 7 , Figure 9-10 In order to ensure that the main retractable bracket 42 can be stably installed on the assembly bracket 41 in a relatively sliding manner, and to ensure that the alignment adjustment component 44 is stably assembled on the assembly bracket 41 and realizes power connection with the main retractable bracket 42, the following technical solution is provided.

[0066] Two sets of parallel guide rails 412 are fixedly connected to the assembly bracket 41 , a sliding bracket 421 is fixedly connected to the middle section of the main retractable bracket 42 , and a guide slot 422 that is slidably combined with the guide rails 412 is fixedly connected to the sliding bracket 421 .

[0067] The alignment adjustment assembly 44 includes a reciprocating screw A441 and a rotational seat A442. The reciprocating screw A441 is rotatably installed in the assembly bracket 41, and the rotational seat A442 is fixed to the sliding bracket 421 and maintains rotational connection with the reciprocating screw A441.

[0068] The matching combination of the guide rail 412 and the guide slot 422 on the sliding bracket 421 can ensure that the sliding bracket 421 and the auxiliary storage bracket slide stably in the assembly bracket 41, thereby realizing the alignment adjustment of the spraying assembly 46. When the reciprocating screw A441 is running, it can drive the rotating seat A442, the sliding bracket 421, and the main retractable bracket 42 to slide stably back and forth.

[0069] In order to ensure that the two sets of auxiliary retractable brackets 43 are stably installed on the main retractable bracket 42 in a relatively sliding manner, and to ensure that the retractable adjustment component 45 can drive the two sets of auxiliary retractable brackets to slide stably, the following technical solution is provided.

[0070] A guide shaft 423 arranged along the length direction of the main retractable bracket 42 is fixedly connected to the main retractable bracket 42 , and a guide seat 431 which maintains a sliding combination with the guide shaft 423 is fixedly connected to the auxiliary retractable bracket 43 .

[0071] Two sets of parallel guide shafts 423 are provided on both sides of the sliding bracket 421. Two sets of guide seats 431 are fixedly connected to the inner ends of the two sets of auxiliary retractable brackets 43, and are respectively slidably connected with the two sets of guide shafts 423 to achieve stable sliding of the auxiliary retractable bracket 43 on the main retractable bracket 42.

[0072] The retractable and retractable adjustment component 45 includes a spline shaft 451, a transmission shaft 452, a reciprocating screw B453, and a rotating seat B454. The spline shaft 451 is rotatably installed on the assembly bracket 41 and remains parallel to the reciprocating screw A441. A driving bevel gear B4511 is slidably inserted on the spline shaft 451. The transmission shaft 452 and the driving bevel gear B4511 are both rotatably installed in the sliding bracket 421. A transmission bevel gear B4521 is fixedly connected to the transmission shaft 452 and remains in mesh with the driving bevel gear B4511.

[0073] The driving bevel gear B4511 can slide synchronously with the sliding bracket 421 and always maintain power connection with the spline shaft 451, so as to ensure that the power of the retracting and extending adjustment component 45 is always stably transmitted during the position adjustment process of the main retracting and extending bracket 42 by the alignment adjustment component 44. When the spline shaft 451 is running, the driving bevel gear B4511 and the transmission bevel gear B4521 can drive the transmission shaft 452 to run stably.

[0074] The reciprocating screw B453 includes two groups which are rotatably mounted on the main retracting and releasing bracket 42 and maintained in a coaxial arrangement. The two retracting and releasing brackets 43 are both fixedly connected with a rotating seat B454. The two groups of rotating seats B454 are respectively rotationally connected to the two groups of reciprocating screws B453. A driving bevel gear C4522 is fixedly connected to the transmission shaft 452. The two groups of reciprocating screws B453 are both fixedly connected with a driving bevel gear C4531 which is meshed with the driving bevel gear C4522.

[0075] The rotating seat B454 is also fixed to the inner end of the auxiliary retractable bracket 43. When the transmission shaft 452 is in operation, it can drive the two sets of reciprocating screws B453 to operate stably through the combination of the driving bevel gear C4522 and the transmission bevel gear C4531. Since the two sets of transmission bevel gears C4531 are arranged symmetrically, the two sets of auxiliary retractable brackets 43 can be driven to slide back and forth stably on the main retractable bracket 42. Example

[0076] See See Figure 6-Figure 8 In order to ensure that the driving assembly 47 can be stably assembled on the assembly bracket 41 and can independently drive the alignment adjustment assembly 44 and the retractable adjustment assembly 45 to operate stably, the following technical solution is provided.

[0077] The driving assembly 47 includes a driving motor 471 and two sets of ratchet mechanisms 472 arranged in opposite directions. The ratchet mechanisms 472 include a mounting shaft 4721, an inner ratchet 4722, and a pawl 4723. The pawls 4723 in the two sets of ratchet mechanisms 472 are rotatably mounted on the periphery of the reciprocating screw A441 and the spline shaft 451, respectively. The pawls 4723 are equipped with a spring leaf 4724 that maintains abutment with the reciprocating screw A441 or the spline shaft 451. The mounting shaft 4721 is rotatably mounted on the assembly bracket 41. The inner ratchet 4722 is coaxially fixed to the mounting shaft 4721 and maintains meshing with the pawl 4723. The mounting shafts 4721 in the two sets of ratchet mechanisms 472 are both fixed with transmission sprockets 4725. The two sets of transmission sprockets 4725 are power-connected through chains. The driving motor 471 is fixedly mounted on the assembly bracket 41 and maintains power connection with one of the sets of mounting shafts 4721.

[0078] When the driving motor 471 is running, the combination of the transmission sprocket 4725 and the chain can drive the two groups of mounting shafts 4721 and the inner ratchet 4722 to maintain synchronous operation. Since the two groups of inner ratchet wheels 4722 are arranged in reverse, when the driving motor 471 is running in the forward direction, one group of ratchet pawls 4723 can be driven to operate stably through the corresponding inner ratchet wheel 4722, thereby stably transmitting power to one group of the reciprocating screw A441 and the spline shaft 451, while the other group of ratchet pawls 4723 is in a sliding state with the inner ratchet wheel 4722 and cannot transmit power. When the driving motor 471 is running in the reverse direction, the other group of ratchet pawls 4723 can be driven to operate through the corresponding inner ratchet wheel 4722, thereby driving the other group of the reciprocating screw A441 and the spline shaft 451 to operate stably.

[0079] The power of the driving motor 471 is diverted and transmitted, thereby driving the independent operation of the alignment adjustment component 44 and the retractable adjustment component 45 .

[0080] In order to ensure that the driving motor 471 can stably transmit power to the mounting shafts 4721 in the two sets of ratchet mechanisms 472, the following technical solution is provided.

[0081] The driving assembly 47 also includes a worm wheel B473 and a worm B474 that maintain a matching combination, wherein a worm wheel B473 is fixedly connected to a set of mounting shafts 4721, and the worm B474 is rotatably mounted on the assembly bracket 41. A reduction bevel gear A4711 is fixedly connected to the output shaft of the driving motor 471, and a reduction bevel gear B4741 that is meshed with the reduction bevel gear A4711 is fixedly connected to the output shaft of the worm B474.

[0082] The number of teeth of the reduction bevel gear A4711 is less than that of the reduction bevel gear B4741. The power of the driving motor 471 can achieve the effect of reducing speed and increasing torque through the combination of the reduction bevel gear A4711, the reduction bevel gear B4741, the worm B474 and the worm wheel B473, so as to drive the reciprocating screw A441 and the spline shaft 451 to operate stably. Example

[0083] See See Figure 11-13 For the spray assembly 46, in order to ensure that the scissor-type mechanism 463 can be stably assembled on the main retractable bracket 42 and the auxiliary retractable bracket 43, and to ensure that the liquid supply pipe 462 can be evenly assembled on the scissor-type mechanism 463 and realize synchronous adjustment of adjacent spacings, the following technical solution is provided.

[0084] The scissor-type mechanism 463 includes multiple groups of parallel arranged connecting rods A4631 and multiple groups of parallel arranged connecting rods B4632. The middle sections of the connecting rods A4631 and B4632 are fixedly connected with sleeves A4633 and B4634 respectively. The liquid supply pipe 462 is rotatably installed in the coaxially arranged sleeves A4633 and B4634. The end of the connecting rod A4631 is hinged with the end of the connecting rod B4632. Pins 4635 are rotatably installed on the connecting rods A and B4632 at both ends of the scissor-type mechanism 463.

[0085] The combination of connecting rod A4631 and connecting rod B4632 can form a scissor-type mechanism 463, which can be adjusted to be telescopic and foldable, and ensure that the liquid supply pipe 462 in the sleeve A4633 and sleeve B4634 can be adjusted to equal spacing when the scissor-type mechanism 463 is telescopically adjusted.

[0086] A guiding groove A424 is provided at the bottom of the main retractable bracket 42, and the outer end of the guiding groove A424 extends to the outer end of the main retractable bracket 42. Guide grooves B432 are provided on both sets of auxiliary retractable brackets 43, and the inner ends of the guiding grooves B432 extend to the inner ends of the auxiliary retractable brackets 43. Two sets of limiting sliding grooves 433 are provided at the outer ends of the auxiliary retractable brackets 43.

[0087] Each group of sleeves A4633 is arranged in the guide groove A424, each group of sleeves B4634 is arranged in the guide groove B432, and each group of pins 4635 is respectively assembled in the corresponding limiting sliding groove 433.

[0088] The guide groove A424 is combined with the sleeve A4633, and the guide groove B432 is stably combined with the sleeve B4634. During the telescopic adjustment of the scissor-type mechanism 463, it can be ensured that the guide sleeve A4633, the guide sleeve B4634, the liquid supply pipe 462, and the nozzle 461 are all stably adjusted along the same straight line.

[0089] The combination of the limiting slide groove 433 and the pin shaft 4635 can ensure that the scissor-type mechanism 463 can be telescopically adjusted, and ensure that the scissor-type mechanism 463 is stably assembled on the main retractable bracket 42 and the auxiliary retractable bracket 43.
