Description

Technical Field

[0001] The present application relates to fertilizing operation equipment, and specifically to an automated pneumatic spreading device, which is suitable for spreading fertilizers on vegetation in municipal engineering and landscaping. Background Art

[0002] Currently, fertilizer spreading equipment is mainly divided into broadcast fertilizer spreaders, trench fertilizer spreaders, and intelligent variable fertilizer systems. Broadcast fertilizer spreaders (including centrifugal and swing types) generally have high operating efficiency and are suitable for large areas of farmland. Among them, centrifugal spreaders spread fertilizer evenly over a wide area, and swing types have better precision in powdered fertilizers. However, they are sensitive to fertilizer form and often cannot handle clumping organic fertilizers or adapt to mixed fertilizers, and they have high energy consumption. Trench fertilizer spreaders accurately control the depth of fertilization and are suitable for orchards with complex terrain. Layering technology can improve fertilizer efficiency, but there are problems with unstable soil cover and limited adaptability. The intelligent variable fertilizer system uses GPS, sensors, and algorithms to achieve dynamic adjustment to improve accuracy and adaptability. However, it is highly dependent on expensive sensors and maintenance technology, and the application threshold for small and medium-sized farmers is high.

[0003] It can be seen that the common defects of existing equipment are concentrated in the aspects of adaptability, precision, cost and environmental protection. Most equipment is not compatible with multiple fertilizer forms, and the operation is easily affected by wind speed and slope; the lack of real-time feedback in traditional machinery leads to inaccurate fertilizer application, resulting in waste or local over-application, and the intelligent system is also constrained by the stability of the algorithm; in terms of cost, high-end intelligent systems require huge initial investment, while traditional machinery has environmental problems such as high energy consumption and reliance on diesel power, resulting in high carbon emissions. The industry urgently needs to seek breakthroughs in lightweighting and energy reduction, multi-sensor algorithm optimization and new energy power applications (such as electric / hydrogen energy) to improve overall adaptability and resolve the contradiction between cost and environmental protection, so as to achieve accurate and efficient fertilization methods.

DETAILED DESCRIPTION

[0027] The following non-limiting examples illustrate the present application.

[0028] Example

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

[0030] The barrel 1 houses a storage bin 2 for storing fertilizer. A discharge port is located at the bottom of the bin 2, connected to the receiving end of a tee pipe 11. This allows the fertilizer in the bin 2 to fall into the tee pipe 11. A flow control mechanism is located at the receiving end of the tee pipe 11, which regulates the speed of the fertilizer flowing through it to meet different spraying requirements.

[0031] The air inlet of the tee pipe 11 is connected to the fan 12, and the discharge end of the tee pipe 11 is connected to the spraying pipe group. Fertilizer enters the intersection of the tee pipe 11 through the inlet end, and air drawn in from the outside also enters the intersection of the tee pipe 11 through the air inlet end. At the intersection, high-pressure air carries fertilizer particles out of the discharge end and is sprayed onto the fields through the spraying pipe group.

[0032] The barrel 1 is similar in shape and size to conventional liquid-filled barrels used for pesticide spraying. Arranged from top to bottom within the barrel 1 are a storage bin top plate 3, a storage bin bottom plate 5, and a barrel bottom plate 8. The sidewalls of the barrel 1, the storage bin top plate 3, and the storage bin bottom plate 5 together form a storage bin 2. The sidewalls of the barrel 1, the storage bin bottom plate 5, and the barrel bottom plate 8 together form an equipment bin 7, with the storage bin 2 located at the top and the equipment bin 7 at the bottom.

[0033] The top of the storage bin 2, i.e., the top plate 3, is provided with a loading port, which is provided with a detachable bin cover 4, which is specifically detachably connected by threads. The bin cover 4 is opened when loading and closed when 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 installed between the storage bin floor 5 and the barrel floor 8. The flow control mechanism is located within the equipment compartment 7. The connecting plates 9 increase the support strength of the floor and also facilitate the placement of the flow control mechanism. The fan 12 and battery 16 are located on the bottom surface of the barrel floor 8. The fan 12 is externally located for easy air intake, and the battery 16 is externally located for easy replacement and heat dissipation. The battery 16 powers the fan 12 and the flow control mechanism.

[0035] Two shoulder straps 6 are provided on the front of the barrel 1 to facilitate carrying. The bottom of the barrel 1 is provided with multiple legs 10, arranged along the outer edge of the barrel 1. The legs 10 are higher than the fan 12 and battery 16 to prevent external components from touching the ground. The material connection end of the tee pipe 11 is routed through the barrel bottom plate 8.

[0036] The spraying tube assembly includes a flexible hose 13, a long spraying tube 14, and a spraying port 15. The flexible hose 13 is connected to the discharge end of the tee 11, which in turn is connected to the long spraying tube 14, which in turn is connected to the spraying port 15. The flexible hose 13 facilitates the swinging operation of the rear-end spraying tube 14, while the operator holds the long spraying tube 14 to perform the specific spraying operation. The spraying port 15 is trumpet-shaped, which facilitates the uniform dispersion of the fertilizer particles.

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

[0038] The adjusting sleeve 22 and adjusting wheel 23 are both located at the adjusting side opening 17 of the material receiving end of the tee pipe 11, so that the adjusting sleeve 22 and adjusting wheel 23 can partially extend into the material receiving end to adjust the fertilizer in the pipe. The adjusting sleeve 22 and adjusting wheel 23 are both cylindrical structures to ensure that their own rotation will not interfere with other components.

[0039] The outer circumference of the adjustment sleeve 22 is smooth and does not push the fertilizer. The inner circumference of the adjustment sleeve 22 is provided with a tooth groove 24. The outer circumference of the adjustment wheel 23 is provided with a shifting tooth 25 that fits within the tooth groove 24. Specifically, the shifting tooth 25 on the adjustment wheel 23 pushes the fertilizer. One end of the adjustment wheel 23 is the shifting tooth 25, and the other end is smooth and inactive. Due to the nesting relationship between the adjustment sleeve 22 and the adjustment wheel 23, changing the relative nesting position between the two can change the exposed width of the shifting tooth 25, achieving different pushing effects and achieving flow regulation.

[0040] The adjustment sleeve 22 and / or adjustment wheel 23 are sleeved onto the first transmission rod 21 along the rod direction and connected to the push-pull drive assembly. This means that the adjustment sleeve 22 and / or adjustment wheel 23 are movable along the rod direction of the first transmission rod 21, and the push-pull drive assembly is used to drive the relative sleeve position between the sleeve and the adjustment wheel 23 to change. In this embodiment, the adjustment sleeve 22 is preferably fixed relative to the rod direction, while the adjustment wheel 23 is sleeved and movable relative to the rod direction. The push-pull drive assembly only performs push-pull adjustment on the adjustment wheel 23.

[0041] The first transmission rod 21, the adjusting sleeve 22 and the adjusting wheel 23 are all arranged in a direction perpendicular to the pipe direction of the receiving end of the tee pipe 11. The rotation of the shifting teeth 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. The first motor 18 is fixed to the first platform 19 within the equipment compartment 7 and is connected to the first transmission rod 21 via the first gear set 20. By changing the speed of the first motor 18, the pushing rate of the shifting gear 25 can also be changed, 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 wire wheel 30, a slide 31, an adjusting wire groove 32, and a clip 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 in the equipment compartment 7.

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

[0045] The slide 31 is arranged within the equipment compartment 7 to slide along the first transmission rod 21. Specifically, the slide 31 is placed on the top surface of the barrel bottom plate 8 and is inserted through a connecting plate 9 to achieve its own sliding arrangement. The slide 31 is provided with clips 33 on both sides of the rod to retain the adjustment sleeve 22 and / or adjustment wheel 23. When the slide 31 slides along the rod, it also slides the adjustment sleeve 22 and / or adjustment wheel 23 along the rod, thereby changing the exposed width of the shifting teeth 25.

[0046] The outer periphery of the adjusting sleeve 22 and / or the adjusting wheel 23 is provided with a locking flange, and the clip 33 is an arc-shaped structure that matches the outer periphery of the adjusting sleeve 22 and / or the adjusting wheel 23. The clip 33 can both perform a rod-direction locking effect on the locking flange without affecting 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 , but a single push-pull drive assembly may act on the adjusting sleeve 22 , or two push-pull drive assemblies may act on the adjusting sleeve 22 and the adjusting wheel 23 respectively.

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

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