Description

Technical Field

[0001] The invention relates to the technical field of agricultural fertilization, and in particular to a precise application device for liquid fertilizer specially used for hanging melons. Background Art

[0002] The melon has a strong adaptability to the growth environment. It likes warmth and is cold-resistant, but not drought-resistant or waterlogged. Therefore, it can be planted in flat terrain, good drainage and irrigation conditions, deep soil, and relatively fertile soil. As a specialty crop, the melon has certain special requirements for fertilizers during its growth. The root distribution, nutrient absorption capacity, and response to different fertilizers of the melon all determine the choice of fertilization method and the determination of fertilizer amount.

[0003] The fertilization equipment in the prior art usually adopts fixed application nozzles. Although such equipment can regulate soil fertility to a certain extent, it also has some defects. Fixed nozzles can usually only apply fertilizer at preset positions, which may lead to uneven spatial distribution of fertilizer in the soil; some areas may get too much fertilizer, while other areas may not get enough.

[0004] In summary, how to solve the problem of uneven fertilizer distribution caused by the fertilization equipment using fixed nozzles in the prior art has become a difficult problem that needs to be solved urgently in this field. Therefore, it is necessary to propose a precise application equipment for liquid fertilizer specially used for hanging melons. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a precise application device for liquid fertilizer specially used for hanging melons. By adjusting the position of the delivery pipe, the device can not only apply fertilizer to different soil layer depths where the roots are located to meet the fertilizer needs of crops at different growth stages; it can also spray fertilizer on the stems and leaves and the surface of the hanging melons, thereby increasing the uniformity of fertilization of the equipment.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a kind of precise application equipment of liquid fertilizer specially used for hanging melons, comprising a main frame, a connecting rod and a storage barrel, the storage barrel is fixedly connected to the top of the main frame, a top cover is detachably connected to the top of the storage barrel, a conveying port is opened at the bottom of the storage barrel, and a plurality of conveying pipes are connected to the bottom of the conveying port.

[0007] The main frame is respectively provided with a lateral adjustment component for adjusting the horizontal direction of the conveying pipe, a vertical adjustment component for adjusting the height of the conveying pipe, a spraying component for spraying fertilizers and a driving component for driving the equipment to move.

[0008] The vertical adjustment component includes a control system, several transmission wheels, a transmission belt and a fixed plate. The fixed plates are symmetrically installed on both sides of the main frame along the length direction; the transmission wheels are rotatably matched with the fixed plates, and the transmission belts are rotatably matched with the outside of the transmission wheels and are installed vertically.

[0009] The conveying pipes can be detachably connected to the connecting rods, both ends of the connecting rods are fixedly connected with square plates, and the square plates are fixedly connected to the outer wall of one side of the conveyor belt.

[0010] A first driving member for driving the transmission wheel to rotate is provided on one of the transmission wheels, and the control system is used to control the operation of the first driving member; the output shaft of the first driving member passes through the adjacent fixed plate and is coaxially fixedly connected to the transmission wheel; a vertical limit assembly for limiting the vertical movement of the connecting rod is provided on the fixed plate.

[0011] The technical principles of the above scheme are as follows:

[0012] The transmission wheel coaxially connected to it is driven to rotate by the first driving member provided. Since the outer side of the transmission wheel is rotated with a transmission belt, the outer wall of one side of the transmission belt is fixedly connected with a square plate, and the square plate is fixedly connected to the connecting rod; so when the transmission wheel drives the transmission belt to rotate, the square plate fixedly connected to the transmission belt can slide vertically, and the connecting rod can be driven to slide vertically synchronously when the square plate moves. Since the storage barrels are connected to the conveying pipe, the conveying pipe can be detachably connected to the connecting rod; so the conveying pipe can be driven to move in the vertical direction by the vertical movement of the connecting rod, so that the fertilizer inside the storage barrel can flow into the conveying pipe for vertical height adjustment. At the same time, the horizontal position of the conveying pipe can be adjusted by the lateral adjustment component provided; the spraying of fertilizer is realized by the spraying component. In this way, not only the fertilizer can penetrate into the soil layer, but also its depth can be adjusted, and the fertilizer spraying on the stems and leaves of the melon and the surface of the melon can be realized, thereby increasing the uniformity of equipment fertilization.

[0013] The above scheme has the following beneficial effects:

[0014] 1. The present invention can realize vertical movement of the conveyor belt and the conveying pipe through precise control of the first driving member, thereby accurately adjusting the height of the conveying pipe. This enables the fertilizer to be accurately delivered to different soil depths where the roots of the melon plants are located, meeting the fertilizer needs of crops at different growth stages.

[0015] 2. The present invention can determine the number and location of the delivery pipes to be installed according to actual needs by detachably connecting the delivery pipes to the connecting rods, thereby ensuring that the fertilizer can be accurately sprayed at the target location; it can be adjusted according to different growth stages of crops and specific fertilization needs, making fertilization more personalized and refined.

[0016] 3. The present invention enables the delivery pipe to move freely in the horizontal direction by adding a lateral adjustment component. Combined with the use of the spraying component, it can achieve uniform spraying of fertilizer inside the soil, on the soil surface, on the roots, stems, leaves and the surface of the melon; ensuring that the fertilizer can evenly cover the entire farmland area and provide balanced nutritional support for the melon plants.

[0017] Furthermore, the vertical limit assembly includes a plurality of first slide rails and first sliders; the first slide rails are fixedly connected to the side of the fixed plate close to the conveyor belt, and the first sliders are vertically slidably matched with the outer side wall of the first slide rails; the side of the first slider away from the first slide rails is fixedly connected to the square plate.

[0018] Beneficial effects: Since the fixed plate is installed symmetrically, the first slide rails are fixedly connected to the fixed plate, and the first sliders are vertically slidably matched with the first slide rails; the first sliders are fixedly connected to the square plate; so when the conveyor belt drives the connecting rod to rise and fall in the vertical direction, the first slider slides along the first slide rail to ensure that the lifting and lowering action of the conveying pipe is smooth and without shaking. Through the cooperation of the first slide rail and the first slider, a stable vertical motion track is provided for the square plate and the connecting rod; ensuring that the equipment can accurately adjust the height of the conveying pipe during the fertilization process, thereby achieving precise fertilization.

[0019] Furthermore, the lateral adjustment component includes a driving gear, a rack and a second driving member for rotating the driving gear, and the control system is used to control the operation of the second driving member; a vertical plate is fixedly connected to the bottom of the first driving member, and the second driving member is fixedly connected to the first driving member through the vertical plate; the vertical plate is fixedly connected to the bottom of the fixed plate, the output shaft of the second driving member is coaxially fixedly connected to the driving gear, the driving gear and the rack are meshed with each other, and the rack is fixedly connected to the inner side wall of the main frame close to the second driving member; a horizontal limit assembly is provided on the main frame for limiting the horizontal movement of the connecting rod.

[0020] Beneficial effects: Since the second driving member is fixedly connected to the bottom of the first driving member through the vertical plate, the output shaft of the second driving member is coaxially fixedly connected to the driving gear, and the driving gear is meshed with the rack fixedly connected to the main frame; therefore, the rotational movement of the driving gear will be converted into lateral movement in the horizontal direction; the lateral movement of the driving gear drives the lateral movement of the second driving member and the first driving member in the horizontal direction. Since the vertical plate is fixedly connected to the fixed plate, when the first driving member and the second driving member move horizontally in the horizontal direction, they can drive the vertical plate and the fixed plate to move horizontally together, and the fixed plate drives the connecting rod to move horizontally. In this way, the connecting rod can be accurately adjusted in the horizontal direction; it helps the equipment to adjust the position of the conveying pipe according to actual needs during the fertilization process, so as to achieve more accurate fertilization.

[0021] Furthermore, the transverse limit assembly includes a plurality of limit plates and a second slider, the limit plates are all located below the fixed plate, and the limit plates are symmetrically fixedly connected to both sides of the main frame; the outer walls of the limit plates are fixedly connected with the second slide rails, and the second sliders are horizontally slidably matched with the outer walls of the second slide rails; the second sliders are fixedly connected to the inner walls of the vertical plates and fixed plates adjacent to them; the outer wall of the main frame close to the rack side is fixedly connected with a support plate, and an opening is opened on the support plate for the movement of the first driving member and the second driving member.

[0022] Beneficial effects: Because the limit plates are symmetrically fixedly connected to both sides of the main frame, the outer side walls of the limit plates are fixedly connected to the second slide rails, and the second sliders are horizontally slidably matched with the outer side walls of the second slide rails; therefore, the movement trajectory of the second slider can be limited to horizontal lateral movement through the second slide rails. Since the first driving member and the second driving member are fixedly connected through the vertical plate, the second sliders are fixedly connected to the vertical plate and the inner side wall of the fixed plate adjacent thereto; therefore, when the first driving member and the second driving member move horizontally in the horizontal direction, the position of the connecting rod can be prevented from shifting by the symmetrical design of the second slider. And since the main frame is fixedly connected to a support plate, and the support plate has an opening for the movement of the first driving member and the second driving member, the support plate can support the first driving member and the second driving member, so that their movement directions remain consistent, further increasing the stability of the equipment.

[0023] Furthermore, the spray assembly includes a long rod and a plurality of spray heads, and the spray heads are all connected to the bottom of the delivery port; an electromagnetic valve is fixedly connected inside the spray head, and the control system is used to control the operation of the electromagnetic valve; a connecting rod is fixedly connected to a plurality of cross bars, and one end of the cross bar away from the connecting rod is fixedly connected to the long rod; the spray heads can be detachably connected to the long rod.

[0024] Beneficial effects: Since the connecting rod is fixedly connected to a plurality of cross rods, and the cross rod is fixedly connected to the long rod; therefore, when the connecting rod moves in the vertical and horizontal directions, the long rod can be driven to move synchronously. Since the spray heads can be detachably connected to the long rod, the movement position of the spray heads can be adjusted by moving the long rod, so that the spray heads can spray on the stems and leaves or the surface of the fruit of the melon; and since the spray heads are detachably connected to the long rod, the number and position of the spray heads can be selected according to actual needs, so that the spray heads can ensure accurate delivery of fertilizers.

[0025] Furthermore, the driving assembly includes a plurality of rotating wheels, and the rotating wheels are all rotatably matched with the bottom of the main frame; a third driving member for rotating the rotating wheel is provided above one of the rotating wheels, and the third driving member is fixedly connected to the outer wall of the main frame, and the control system is used to control the operation of the third driving member; the output shaft of the third driving member is coaxially fixedly connected to the main bevel gear, and the main bevel gear is meshed with the secondary bevel gear; the secondary bevel gear is coaxially fixedly connected to the rotating shaft, and the rotating shafts pass through two adjacent rotating wheels and are coaxially fixedly connected to the rotating wheels.

[0026] Beneficial effects: The third driving member drives the main bevel gear to rotate, and the main bevel gear drives the driven bevel gear meshing with it to rotate; since the driven bevel gear is coaxially fixed with a rotating shaft, the rotating shaft penetrates the rotating wheel and is coaxially fixedly connected to the rotating wheel; therefore, when the driven bevel gear drives the rotating shaft to rotate, the rotating wheel coaxially fixedly connected to it can be driven to rotate. When the rotating wheel rotates, it can drive the device to move, and through such a transmission method, the efficient transmission of power is achieved, further increasing the convenience of the device.

[0027] Furthermore, the conveying pipe and the pipe connecting the spraying head to the conveying port are both flexible hoses, the conveying pipe is a rigid pipe, the conveying pipe is in an "ㄣ" shape, and the lower length of the conveying pipe is greater than the upper length.

[0028] Beneficial effects: The design of the flexible hose enables the positions of the conveying pipe and the spraying head to be adjusted arbitrarily, and the design of the rigid conveying pipe enables it to be stably inserted into the soil layer to directly convey the liquid fertilizer to the roots of the hanging melon plants; thereby improving the utilization rate of fertilizers and the yield of crops.

[0029] Furthermore, the bottom of the storage bucket is in an inverted "冖" shape, a pump assembly is fixedly connected at the conveying port, and the control system is used to control the operation of the pump assembly.

[0030] Beneficial effects: The inverted "冖" shape design of the storage bucket enables the liquid fertilizer to flow out quickly from the inside of the storage bucket, and the design of the pump assembly can further increase the conveying force of the fertilizer, so that the liquid fertilizer is quickly transported and the conveying efficiency of the fertilizer is improved.

[0031] Furthermore, flow regulating valves are fixedly connected to the bottom of the conveying pipes, and the control system is used to control the operation of the flow regulating valves.

[0032] Beneficial effects: By adjusting the opening degree of the flow regulating valve, the precise control of the fertilization amount can be realized, meeting the fertilization requirements of hanging melons at different growth stages. Precise fertilization helps to reduce the waste of fertilizers and improve the utilization rate of fertilizers.

[0033] Furthermore, the control system includes the following modules:

[0034] An information acquisition module for monitoring the soil nutrient status and the growth of hanging melons.

[0035] An analysis and processing module for analyzing and judging the type of fertilizer, fertilization time, fertilization height and fertilization amount applied according to the soil nutrient status and the growth of hanging melons.

[0036] An intelligent control module for performing intelligent control according to a preset fertilization plan; fertilizing the hanging melons regularly, quantitatively and at fixed points.

[0037] The monitoring and feedback module is used to monitor the effects of fertilization, soil nutrients and changes in plant growth status in real time; if insufficient nutrients are found, timely fertilization will be carried out.

[0038] Beneficial effects: By real-time monitoring of soil nutrient status and melon growth, the accuracy and timeliness of fertilization decisions can be further improved; effectively reducing problems such as crop growth stagnation or yield reduction caused by improper fertilization; thereby improving the accuracy and efficiency of fertilization, reducing fertilizer waste and environmental pollution; if nutrients are found to be insufficient, fertilizer can be supplemented in time to ensure healthy growth of crops.

DETAILED DESCRIPTION

[0045] The following is further described in detail through specific implementation methods:

[0046] Embodiment 1:

[0047] As attached Figure 1-Figure 3As shown: a liquid fertilizer precision application equipment specially used for hanging melons, comprising a main frame 1, a connecting rod 3 and a storage barrel 2, the storage barrel 2 is bolted and fixedly connected to the top of the main frame 1, the top of the storage barrel 2 is detachably threadedly connected with a top cover 4, the bottom of the storage barrel 2 is provided with a delivery port, and the bottom of the delivery port is connected to a plurality of delivery pipes 5.

[0048] The main frame 1 is provided with a lateral adjustment component for adjusting the horizontal direction of the conveying pipe 5, a vertical adjustment component for adjusting the height of the conveying pipe 5, a spraying component for spraying fertilizers, and a driving component for driving the equipment to move.

[0049] The vertical adjustment assembly includes a control system, a plurality of transmission wheels 6, a transmission belt 7 and a fixed plate 8, wherein the fixed plate 8 is symmetrically installed on both sides of the main frame 1 along the length direction; the transmission wheels 6 are rotatably matched with the fixed plate 8, and the transmission belts 7 are rotatably matched with the outer side of the transmission wheel 6 and are installed vertically.

[0050] The conveying pipe 5 can be detachably connected to the connecting rod 3 , and both ends of the connecting rod 3 are fixedly connected with square plates 9 by bolts, and the square plates 9 are fixedly connected with the outer wall of one side of the conveying belt 7 by bolts.

[0051] A first driving member for driving the transmission wheel 6 to rotate is provided on one of the transmission wheels 6. In this embodiment, the first driving member is a first motor 10, and the control system is used to control the operation of the first motor 10; the output shaft of the first motor 10 passes through the adjacent fixed plate 8 and is fixedly connected to the transmission wheel 6 by coaxial bolts; the fixed plate 8 is provided with a vertical limit assembly for limiting the vertical movement of the connecting rod 3.

[0052] like Figure 3 As shown, the vertical limit assembly includes a plurality of first slide rails 11 and first sliders 12; the first slide rails 11 are all bolted and fixedly connected to the inner side of the fixed plate 8, and the first sliders 12 are all vertically slidably matched with the outer side wall of the first slide rails 11; the side of the first slider 12 away from the first slide rail 11 is bolted and fixedly connected to the square plate 9.

[0053] Since the fixed plate 8 is installed symmetrically, the first slide rails 11 are all bolted and fixedly connected to the fixed plate 8, and the first sliders 12 are all vertically slidably matched with the first slide rails 11; the first sliders 12 are all bolted and fixedly connected with the square plate 9; so when the conveyor belt 7 drives the connecting rod 3 to rise and fall in the vertical direction, the first slider 12 slides along the first slide rail 11 to ensure that the lifting and lowering action of the conveying pipe 5 is smooth and without shaking. Through the cooperation of the first slide rail 11 and the first slider 12, a stable vertical motion track is provided for the square plate 9 and the connecting rod 3; ensuring that the equipment can accurately adjust the height of the conveying pipe 5 during the fertilization process, thereby achieving precise fertilization.

[0054] The lateral adjustment component includes a driving gear 13, a rack 14 and a second driving member for rotating the driving gear 13. In this embodiment, the second driving member is a second motor 15, and the control system is used to control the operation of the second motor 15; a vertical plate 16 is bolted fixedly connected to the bottom of the first motor 10, and the second motor 15 is bolted fixedly connected to the first motor 10 through the vertical plate 16; the vertical plate 16 is bolted fixedly connected to the bottom of the fixed plate 8, and the output shaft of the second motor 15 is coaxially bolted and fixedly connected with the driving gear 13, the driving gear 13 and the rack 14 are meshed with each other, and the rack 14 is bolted fixedly connected to the inner wall on the left side of the main frame 1; a transverse limit assembly for limiting the horizontal movement of the connecting rod 3 is provided on the main frame 1.

[0055] like Figure 1 and Figure 3 As shown, the transverse limit assembly includes a plurality of limit plates 17 and a second slider, the limit plates 17 are all located below the fixed plate 8, and the limit plates 17 are symmetrically bolted and fixedly connected to both sides of the main frame 1; the outer walls of the limit plates 17 are bolted and fixedly connected to the second slide rails, and the second sliders are horizontally slidably matched with the outer walls of the second slide rails; the second sliders are bolted and fixedly connected to the inner walls of the adjacent vertical plates 16 and the fixed plate 8; the outer wall of the main frame 1 close to the rack 14 is bolted and fixedly connected to the support plate 18, and the support plate 18 is provided with an opening for the movement of the first motor 10 and the second motor 15.

[0056] Because the limit plate 17 is symmetrically bolted and fixedly connected to both sides of the main frame 1, the outer wall of the limit plate 17 is bolted and fixedly connected with the second slide rail, and the second slider is horizontally slidably matched with the outer wall of the second slide rail; therefore, the movement trajectory of the second slider can be limited to horizontal lateral movement in the horizontal direction through the second slide rail. Since the first motor 10 and the second motor 15 are bolted and fixedly connected through the vertical plate 16, the second slider is bolted and fixedly connected with the vertical plate 16 and the inner wall of the fixed plate 8 adjacent thereto; therefore, when the first motor 10 and the second motor 15 move horizontally in the horizontal direction, the position of the connecting rod 3 can be prevented from shifting by the symmetrical second slider design. And since the support plate 18 is bolted and fixedly connected to the main frame 1, and the support plate 18 has an opening for the movement of the first motor 10 and the second motor 15, the support plate 18 can support the first motor 10 and the second motor 15, so that their movement directions remain consistent, further increasing the stability of the equipment.

[0057] like Figure 1 and Figure 3As shown, since the output shaft of the second motor 15 is coaxially bolted to the driving gear 13, the driving gear 13 is meshed with the rack 14 bolted to the main frame 1; therefore, the rotational movement of the driving gear 13 is converted into lateral movement in the horizontal direction; the lateral movement of the driving gear 13 drives the lateral movement of the second motor 15 and the first motor 10 in the horizontal direction. Since the vertical plate 16 is bolted to the fixed plate 8, when the first motor 10 and the second motor 15 move horizontally in the horizontal direction, they can drive the vertical plate 16 and the fixed plate 8 to move horizontally together, and the fixed plate 8 drives the connecting rod 3 to move horizontally. Figure 3 For example, when the driving gear 13 rotates clockwise, it can drive the connecting rod 3 to move to the right; conversely, when the driving gear 13 rotates counterclockwise, it can drive the connecting rod 3 to move to the left, thereby realizing the reciprocating motion of the connecting rod 3 in the horizontal direction. In this way, the connecting rod 3 can be precisely adjusted in the horizontal direction; it is helpful for the equipment to adjust the position of the conveying pipe 5 according to actual needs during the fertilization process, thereby realizing more accurate fertilization.

[0058] like Figure 1 As shown, the spray assembly includes a long rod and a plurality of spray heads 19, and the spray heads 19 are all connected to the bottom of the delivery port; the spray head 19 is internally bolted and connected to a solenoid valve, and the control system is used to control the operation of the solenoid valve; the connecting rod 3 is bolted and connected to a plurality of cross bars 20, and the ends of the cross bars 20 away from the connecting rod 3 are bolted and connected to the long rod; the spray heads 19 can be detachably engaged and connected to the long rod.

[0059] The pipes connected to the delivery port of the delivery pipe 5 and the spray head 19 are both hoses, and the delivery pipe 5 is a hard pipe, and the delivery pipe 5 is in the shape of a "ㄣ", and the length of the lower part of the delivery pipe 5 is greater than the length of the upper part. The design of the hose allows the positions of the delivery pipe 5 and the spray head 19 to be adjusted at will, and the design of the hard pipe of the delivery pipe 5 allows it to be stably inserted into the soil layer, and the liquid fertilizer is directly delivered to the root of the melon plant, thereby improving the utilization rate of the fertilizer and the yield of the crop.

[0060] Since the connecting rod 3 is bolted and fixedly connected with a plurality of cross bars 20, and the cross bars 20 are bolted and fixedly connected with the long rod, when the connecting rod 3 moves in the vertical and horizontal directions, the long rod can be driven to move synchronously. Since the spraying head 19 can be detachably engaged and connected to the long rod, the moving position of the spraying head 19 can be adjusted by the movement of the long rod, so that the spraying head 19 can spray on the stems and leaves or the surface of the fruit of the melon; and since it is detachably engaged and connected with the long rod, the installation quantity and installation position of the spraying head 19 can be selected according to actual needs, so that the spraying head 19 can ensure accurate delivery of fertilizer.

[0061] like Figure 1 and Figure 2As shown, the driving assembly includes a plurality of rotating wheels 21, and the rotating wheels 21 are all rotatably matched with the bottom of the main frame body 1; a third driving member for rotating the rotating wheel 21 is provided above one of the rotating wheels 21, and the third driving member in this embodiment is a third motor 22, and the third motor 22 is bolted and fixedly connected to the outer wall of the main frame body 1, and the control system is used to control the operation of the third motor 22; the output shaft of the third motor 22 is coaxially bolted and fixedly connected to the main bevel gear 23, and the main bevel gear 23 is meshed with a secondary bevel gear 24; the secondary bevel gear 24 is coaxially bolted and fixedly connected to the rotating shaft 25, and the rotating shaft 25 passes through two adjacent rotating wheels 21 and is coaxially bolted and fixedly connected to the rotating wheel 21.

[0062] The main bevel gear 23 is driven to rotate by the third motor 22, and the main bevel gear 23 drives the meshing auxiliary bevel gear 24 to rotate; since the auxiliary bevel gear 24 is coaxially bolted with a rotating shaft 25, the rotating shaft 25 penetrates the rotating wheel 21 and is coaxially bolted and fixedly connected with the rotating wheel 21; therefore, when the auxiliary bevel gear 24 drives the rotating shaft 25 to rotate, the rotating wheel 21 coaxially bolted and fixedly connected with the rotating wheel 21 can rotate. When the rotating wheel 21 rotates, it can drive the device to move. Through such a transmission method, the power is efficiently transmitted, further increasing the convenience of the device.

[0063] The specific implementation process is as follows: Figure 1 and Figure 3 As shown, the transmission wheel 6 coaxially bolted and connected thereto is driven to rotate by the first motor 10. Since the outer side of the transmission wheel 6 is rotated and matched with the transmission belt 7, the outer wall of one side of the transmission belt 7 is bolted and connected to the square plate 9, and the square plate 9 is bolted and connected to the connecting rod 3; therefore, when the transmission wheel 6 drives the transmission belt 7 to rotate, the square plate 9 bolted and connected to the transmission belt 7 can slide vertically, and the square plate 9 can drive the connecting rod 3 to slide vertically synchronously. Since the storage barrels 2 are connected to the conveying pipe 5, the conveying pipe 5 can be detachably connected to the connecting rod 3; therefore, the vertical movement of the connecting rod 3 can drive the conveying pipe 5 to move in the vertical direction, so that the fertilizer inside the storage barrel 2 flows into the conveying pipe 5 for vertical height adjustment.

[0064] by Figure 3For example, when the first motor 10 drives the transmission wheel 6 to rotate clockwise, the right side of the conveyor belt 7 moves downward, and when moving, it drives the delivery pipe 5 on the connecting rod 3 to move downward synchronously; conversely, when the first motor 10 drives the transmission wheel 6 to rotate counterclockwise, it can drive the delivery pipe 5 to move upward through the connecting rod 3, and the height position of the delivery pipe 5 is adjusted in this way. This enables the fertilizer to be accurately delivered to different soil depths where the roots of the hanging melon plants are located, meeting the fertilizer requirements of the hanging melons at different growth stages. Moreover, by detachably snap-connecting the delivery pipe 5 to the connecting rod 3, the installation quantity and installation position of the delivery pipe 5 can be determined according to actual needs, ensuring that the fertilizer can be precisely sprayed at the target position; it can be adjusted according to different growth stages of the crop and specific fertilization requirements, making fertilization more personalized and refined.

[0065] Meanwhile, the horizontal position of the delivery pipe 5 can be adjusted by the provided second motor 15; the fertilizer is sprayed by the spray head 19. In this way, not only can the fertilizer penetrate deep into the soil layer, but also the spraying position can be adjusted, and uniform spraying of the fertilizer on the inner part of the soil, the soil surface, the roots, leaves and the surface of the hanging melons can be achieved; ensuring that the fertilizer can evenly cover the entire farmland area, providing balanced nutritional support for the hanging melon plants.

[0066] Embodiment 2:

[0067] As shown in the attached Figure 1 and Figure 2 figure, the difference from the above embodiment is that the bottom of the storage barrel 2 is in an inverted "冖" shape, and a pump assembly is fixedly connected by bolts at the delivery port. In this embodiment, the pump assembly is a water pump 26, and the control system is used to control the operation of the water pump 26.

[0068] The specific implementation process is as follows: The inverted "冖" shape design of the storage barrel 2 enables the liquid fertilizer to flow out quickly from the inside of the storage barrel 2. The design of the water pump 26 can further increase the conveying force of the fertilizer, so that the liquid fertilizer is quickly transported, improving the fertilizer conveying efficiency.

[0069] Embodiment 3:

[0070] As shown in the attached Figure 1 and Figure 2 figure, the difference from the above embodiment is that flow regulating valves 27 are fixedly connected by bolts at the bottoms of the delivery pipes 5, and the control system is used to control the operation of the flow regulating valves 27.

[0071] The specific implementation process is as follows: By adjusting the opening degree of the flow regulating valve 27, precise control of the fertilization amount can be achieved, meeting the fertilization requirements of the hanging melons at different growth stages. Precise fertilization helps to reduce fertilizer waste and improve fertilizer utilization efficiency.

[0072] Embodiment 4:

[0073] As attached Figure 4 As shown, the difference from the above embodiment is that the control system includes an information acquisition module, an analysis and processing module, an intelligent control module and a monitoring feedback module.

[0074] The information collection module is used to monitor soil nutrient status and melon growth.

[0075] The analysis and processing module is used to analyze and determine the type, time, height and amount of fertilizer to be applied based on the soil nutrient status and the growth of the melon.

[0076] The intelligent control module is used to perform intelligent control according to a preset fertilization plan; and to fertilize the hanging melon at a fixed time, quantity and location.

[0077] The monitoring and feedback module is used to monitor the effects of fertilization, soil nutrients and changes in plant growth status in real time; if nutrients are found to be insufficient, timely fertilization will be carried out.

[0078] The specific implementation process is as follows: through real-time monitoring of soil nutrient status and melon growth, the accuracy and timeliness of fertilization decisions can be further improved; effectively reduce problems such as crop growth stagnation or yield reduction caused by improper fertilization; thereby improving the accuracy and efficiency of fertilization, reducing fertilizer waste and environmental pollution; if nutrients are found to be insufficient, fertilizer can be supplemented in time to ensure healthy growth of crops.

[0079] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
