Description

Technical Field

[0001] This application pertains to fertilizer application equipment, specifically an automated pneumatic spreading device suitable for spreading fertilizer onto vegetation in municipal engineering and landscaping projects. Background Technology

[0002] Currently, fertilizer application equipment is mainly divided into spreader fertilizer applicators, trenching fertilizer applicators, and intelligent variable-rate fertilizer application systems. Spreader fertilizer applicators (including centrifugal and oscillating types) generally have high operating efficiency and are suitable for large-area farmland. Centrifugal spreaders offer wide-width and even application, while oscillating spreaders provide better precision for powdered fertilizers. However, they are sensitive to fertilizer form and often cannot handle clumped organic fertilizers or mixed fertilizers, and they consume a lot of energy. Trenching fertilizer applicators precisely control the fertilization depth, making them suitable for orchards with complex terrain. Layering technology can improve fertilizer efficiency, but they suffer from unstable soil covering and limited adaptability. Intelligent variable-rate fertilizer application systems achieve dynamic adjustment through GPS, sensors, and algorithms, improving accuracy and adaptability. However, they are highly dependent on expensive sensors and maintenance technology, making them difficult for small and medium-sized farmers to use.

[0003] It can be seen that the common shortcomings of existing equipment are concentrated in adaptability, accuracy, and cost-effectiveness. Most equipment is incompatible with diverse fertilizer forms, and its operation is easily affected by wind speed and slope. Traditional machinery lacks real-time feedback, leading to inaccurate fertilization, waste, or localized over-fertilization. Intelligent systems are also constrained by algorithm stability. In terms of cost, high-end intelligent systems require huge initial investments, while traditional machinery suffers from high energy consumption and reliance on diesel power, resulting in high carbon emissions. The industry urgently needs breakthroughs in lightweight design and energy saving, multi-sensor algorithm optimization, and the application of new energy power sources (such as electric / hydrogen energy) to improve overall adaptability and resolve the cost-environment conflict, achieving precise and efficient fertilization methods.

Detailed Implementation

[0027] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0028] Example

[0029] refer to Figures 1-6As shown, an automated pneumatic spreading device includes a barrel 1, a storage bin 2, a three-way pipe 11, a blower 12, a flow regulating mechanism, and a spray pipe assembly, which can realize fertilizer spreading in municipal engineering and landscaping.

[0030] The barrel 1 contains a storage compartment 2 for storing fertilizer. The bottom of the storage compartment 2 has a discharge port, which connects to the receiving end of the three-way pipe 11, allowing the fertilizer in the storage compartment 2 to fall into the three-way pipe 11. The receiving end of the three-way pipe 11 is equipped with a flow regulating mechanism to control the flow rate of the fertilizer passing through the receiving end, thus meeting different spraying requirements.

[0031] The air inlet of the three-way pipe 11 is connected to the blower 12, and the discharge end of the three-way pipe 11 is connected to the spray pipe assembly. Fertilizer enters the intersection of the three-way pipe 11 through the air inlet, and externally drawn air also enters the intersection of the three-way pipe 11 through the air inlet. At the intersection, high-pressure air carries fertilizer granules and sends them out from the discharge end, which are then sprayed onto the field through the spray pipe assembly.

[0032] The shape and size of the tank 1 are similar to those of a traditional pesticide spraying tank. Inside the tank 1, from top to bottom, there are a storage top plate 3, a storage bottom plate 5, and a tank bottom plate 8. The side walls of the tank 1, the storage top plate 3, and the storage bottom plate 5 together form a storage chamber 2. The side walls of the tank 1, the storage bottom plate 5, and the tank bottom plate 8 together form an equipment chamber 7. The storage chamber 2 is located at the top, and the equipment chamber 7 is located at the bottom.

[0033] The storage bin 2 has a loading port on its top plate 3, which is equipped with a removable cover 4. The cover 4 is detachable via threads. It is opened during loading and closed after loading is complete. The discharge port at the bottom of the storage bin 2 is located on the bottom plate 5.

[0034] Several connecting plates 9 are provided between the storage tank bottom plate 5 and the barrel bottom plate 8. The flow regulation mechanism is located inside the equipment compartment 7. The connecting plates 9 improve the support strength of the bottom plate and also allow the flow regulation mechanism to be installed. The fan 12 and battery 16 are located on the bottom surface of the barrel bottom plate 8. The fan 12 is externally mounted for easy air intake, and the battery 16 is externally mounted for easy replacement and heat dissipation. The battery 16 supplies power to the fan 12 and the flow regulation mechanism.

[0035] Two shoulder straps 6 are provided on the front of the barrel 1 for easy carrying by operators. Support legs 10 are provided at the bottom of the barrel 1. Several support legs 10 are arranged along the outer edge of the barrel 1. The height of the support legs 10 is higher than the height of the fan 12 and battery 16 to prevent external components from touching the ground. The receiving end of the three-way pipe 11 passes through the bottom plate 8 of the barrel.

[0036] The spraying assembly includes a flexible hose 13, a long spraying pipe 14, and a spray nozzle 15. The flexible hose 13 is connected to the discharge end of the three-way pipe 11, the flexible hose 13 is connected to the long spraying pipe 14, and the long spraying pipe 14 is connected to the spray nozzle 15. The flexible hose 13 facilitates the swinging operation of the long spraying pipe 14, while the operator holds the long spraying pipe 14 to perform the actual spraying operation. The spray nozzle 15 is funnel-shaped to facilitate the uniform dispersion of fertilizer granules.

[0037] The flow regulation mechanism includes a rotary drive assembly, a push-pull drive assembly, an adjusting sleeve 22, and an adjusting wheel 23. The rotary drive assembly is connected to the first transmission rod 21, which is rotatably mounted between two connecting plates 9. The rotary drive assembly drives the first transmission rod 21 to rotate. The adjusting sleeve 22 and the adjusting wheel 23 are both synchronously mounted on the first transmission rod 21, meaning the first transmission rod 21 can drive the adjusting sleeve 22 and the adjusting wheel 23 to rotate synchronously.

[0038] Both the adjusting sleeve 22 and the adjusting wheel 23 are located at the adjusting side opening 17 of the receiving end of the tee pipe 11, so that the partial structure of the adjusting sleeve 22 and the adjusting wheel 23 extends into the receiving end to adjust the fertilizer in the pipe. Both the adjusting sleeve 22 and the adjusting wheel 23 are cylindrical structures to ensure that their rotation will not interfere with other components.

[0039] The outer circumference of the adjusting sleeve 22 is smooth and does not push fertilizer. The inner circumference of the adjusting sleeve 22 has a toothed groove 24, and the outer circumference of the adjusting wheel 23 has teeth 25 fitted into the toothed groove 24. Specifically, the fertilizer is pushed by the teeth 25 on the adjusting wheel 23. One end of the adjusting wheel 23 has the teeth 25, and the other end is a smooth surface that does not function. Due to the fitted relationship between the adjusting sleeve 22 and the adjusting wheel 23, changing the relative fitted position between the two can change the exposed width of the teeth 25, resulting in different pushing effects and achieving flow regulation.

[0040] The adjusting sleeve 22 and / or adjusting wheel 23 are sleeved on the first transmission rod 21 along the rod direction and connected to the push-pull drive assembly. That is, the adjusting sleeve 22 and / or adjusting wheel 23 can move along the rod direction of the first transmission rod 21. The push-pull drive assembly drives the two to change their relative sleeved position relationship. In this embodiment, the adjusting sleeve 22 is fixed relative to the rod direction, while the adjusting wheel 23 is sleeved and movable relative to the rod direction. The push-pull drive assembly only adjusts the adjusting wheel 23 by pushing and pulling.

[0041] The first transmission rod 21, the adjusting sleeve 22, and the adjusting wheel 23 are all arranged in a direction perpendicular to the material receiving end of the tee pipe 11. The rotation of the tooth 25 on the adjusting wheel 23 will generate a force along the pipe direction, which will push the fertilizer along the pipe direction, ensuring efficient and direct pushing.

[0042] The rotary drive assembly includes a first motor 18, a first gear set 20, and a first platform 19. The first platform 19 is fixed to the top surface of the barrel bottom plate 8, and the first motor 18 is fixed to the first platform 19 inside the equipment compartment 7. The first motor 18 is connected to the first transmission rod 21 through the first gear set 20. By changing the rotational speed of the first motor 18, the pushing speed of the prying teeth 25 can also be changed, thereby achieving flow regulation.

[0043] The push-pull drive assembly includes a second motor 26, a second platform 27, a second gear set 28, a second transmission rod 29, an adjusting screw wheel 30, a sliding plate 31, an adjusting screw groove 32, and a clamping plate 33. The second platform 27 is also fixed to the top surface of the barrel bottom plate 8, and the second motor 26 is fixed to the second platform 27 inside the equipment compartment 7.

[0044] The second motor 26 is connected to the second transmission rod 29 via the second gear set 28. The second transmission rod 29 is rotatably mounted between the two connecting plates 9. The second transmission rod 29 is connected to the adjusting screw wheel 30. The adjusting screw wheel 30 cooperates with the adjusting screw groove 32 on the slide plate 31. The second motor 26 drives the adjusting screw wheel 30 to rotate, and the sliding movement of the slide plate 31 is realized through the action of the screw wheel and the adjusting screw groove 32.

[0045] The slide plate 31 is slidably arranged in the equipment compartment 7 along the first transmission rod 21. Specifically, the slide plate 31 is placed on the top surface of the barrel bottom plate 8 and passes through a connecting plate 9 to achieve its sliding arrangement. The slide plate 31 is provided with clamping pieces 33 that engage adjusting sleeves 22 and / or adjusting wheels 23 from both sides of the rod. When the slide plate 31 slides along the rod, it also moves the adjusting sleeves 22 and / or adjusting wheels 23 along the rod, thereby changing the exposed width of the gear teeth 25.

[0046] The outer periphery of the adjusting sleeve 22 and / or the adjusting wheel 23 is provided with a locking flange. The clamping piece 33 is an arc-shaped structure that matches the outer periphery of the adjusting sleeve 22 and / or the adjusting wheel 23. Thus, the clamping piece 33 can not only lock the locking flange in the rod direction, but also not affect the normal rotation of the adjusting sleeve 22 and / or the adjusting wheel 23.

[0047] In this embodiment, only a single push-pull drive assembly acts on the adjusting wheel 23. Alternatively, a single push-pull drive assembly can act on the adjusting sleeve 22, or two push-pull drive assemblies can act on the adjusting sleeve 22 and the adjusting wheel 23 respectively.

[0048] The foregoing basic examples and their further alternative examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed in this application. In the scheme of this application, each alternative example can be arbitrarily combined with any other basic example and alternative example.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
