Description

Technical Field

[0001] This invention relates to the field of tricycle technology, specifically a multi-functional, fully automatic gasoline-powered fertilizer-spreading tricycle suitable for both dry and wet applications. Background Technology

[0002] In greenhouse farming or farms with limited planting areas, it is usually necessary to apply fertilizer to the planting area before planting. Fertilizers include regular compound fertilizers, granular fertilizers (dry), compost, and farmyard manure (wet). Current fertilization methods have the following shortcomings:

[0003] 1. Most fertilizers are spread manually, which results in uneven distribution and easy contamination of the user. In addition, the amount of fertilizer carried at one time is small, leading to low work efficiency.

[0004] 2. Existing medium and large-sized diesel-powered fertilizer spreaders on the market are bulky and lack flexibility and portability for use in sheds and space-constrained environments. Their cumbersome and traditional construction is not innovative enough, resulting in poor economic efficiency. Furthermore, diesel engines produce significant exhaust emissions and noise. In summary, to address these issues, the inventor proposes a dual-purpose, multi-functional, fully automatic gasoline-powered fertilizer spreader tricycle for both wet and dry applications. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. The vehicle travels on a three-wheeled vehicle. The gasoline engine drives the gear pump, which delivers hydraulic oil from the tank to a multi-way valve. The multi-way valve controls the oil flow of the opening and closing mechanism and the fertilizer spreading mechanism, thereby hydraulically driving them. The multi-way valve also controls the oil flow of the opening and closing hydraulic cylinder, causing it to extend and retract, thus opening and closing the gate. When the gate is open, the multi-way valve controls the oil flow of the material-dispensing hydraulic motor. This motor drives the material-dispensing shaft to rotate via a transmission sprocket and chain. The shaft then drives the material-dispensing sprocket, causing the chain to rotate. As the chain rotates, waste material from the storage bin is ejected from the outlet. Simultaneously, the return oil from the material-dispensing hydraulic motor drives the slinger hydraulic motor, which in turn drives the slinger to rotate, breaking up the fallen fertilizer and evenly distributing it to the planting area, achieving uniform fertilizer application.

[0018] 2. The tricycle has a narrow body, making it suitable for fertilizing sheds, farms, and grassland slopes. It can also be used to spread salt and other substances when melting snow on roads. In normal times, the storage box can also be used to transport fruits and vegetables, making it a multi-functional machine.

[0019] 3. By replacing the traditional diesel engine with a gasoline engine, optimizing power transmission, hydraulic system, and structure, the health hazards caused by the large emissions and noise of diesel engines are avoided. This achieves noise reduction and emission reduction, reduces the size of the equipment, and brings greater convenience and improves economic efficiency to greenhouse growers, in addition to meeting the needs of outdoor, hillside, and farmland use.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example: Figure 1-9 As shown, the present invention provides a multi-functional fully automatic gasoline-powered fertilizer spreading tricycle for both dry and wet applications, including a tricycle body 1. Two mounting brackets 2 are fixedly installed on the top of the frame of the tricycle body 1. A storage box 3 is fixedly welded to the top of the mounting bracket 2. A drive assembly 4 is installed at the end of the storage box 3 near the front of the tricycle body 1. A mounting plate 5 is bolted to the end of the mounting bracket 2 away from the drive assembly 4. An opening and closing mechanism 6 is installed between the mounting plate 5 and the storage box 3. A fertilizer spreading mechanism 7 is installed between the mounting plate 5 and the mounting bracket 2.

[0033] Through the above technical solution, the storage box 3 can store dry and wet fertilizers such as chemical fertilizers, granular fertilizers and compost. The tricycle body 1 travels along the shed planting area. When traveling, the drive component 4 drives the opening and closing mechanism 6 to open the rear door of the storage box 3. Then the fertilizer spreading mechanism 7 spreads the waste in the storage box 3 and evenly sprinkles it on the planting area, realizing automated fertilizer spreading and uniform fertilizer spreading.

[0034] Furthermore, the bottom of the tricycle body 1 is equipped with a 150-300cc chassis engine, and the output end of the chassis engine is connected to a high / low gear converter.

[0035] Furthermore, the bottom of the tricycle body 1 is equipped with a chassis engine of 150-300cc, which can be selected according to the usage needs. The output end of the chassis engine is connected to a high-low gear converter. The width of the tricycle body 1 is 0.9-1.1 meters, and a power-assisted reverse gear is installed at the front of the tricycle body 1.

[0036] Through the above technical solution, the speed of the tricycle body 1 is changed by the force-reversing gear, which has low speed 1-5, medium speed 1-5, and high speed 1-5. The tricycle body 1 has a narrow and long structure, which facilitates the flexibility and portability of spreading fertilizer in narrow planting areas. Both the drive component 4 and the bottom of the tricycle body 1 are equipped with engines, and the dual power drives the tricycle to move and spread fertilizer respectively.

[0037] Furthermore, the drive assembly 4 includes a gasoline engine 41 and a gear pump 42. The gasoline engine 41 and gear pump 42 are fixedly mounted on the tricycle body 1. The output shaft of the gasoline engine 41 and the input shaft of the gear pump 42 are connected by a drive belt. An oil tank 43 is fixedly mounted on the side wall of the storage box 3. The bottom of the oil tank 43 is connected to the inlet end of the gear pump 42 via an oil pipe. A multi-way valve 44 is fixedly mounted on the tricycle body 1. The outlet end of the gear pump 42 is connected to the inlet end of the multi-way valve 44 via an oil pipe. Multiple outlets are connected to the oil tank 43, the opening and closing mechanism 6, and the fertilizer spreading mechanism 7 via oil pipes. The top of the oil tank 43 has multiple return oil ports and oil filling ports. A filter 45 is installed inside the oil tank 43. A hydraulic oil level and temperature gauge 47 is fixedly installed on the oil tank 43. A radiator 46 is fixedly installed on the tricycle body 1 at the multi-way valve 44. The inlet end of the radiator 46 is connected to the return oil pipe of the fertilizer spreading mechanism 7, and the outlet end of the radiator 46 is connected to the return oil port via an oil pipe. A 12V cooling fan is provided at the radiator 46.

[0038] Through the above technical solution, the gasoline engine 41 drives the gear pump 42, which delivers the hydraulic oil in the oil tank 43 to the multi-way valve 44. The multi-way valve 44 controls the oil circuit opening and closing mechanism 6 and the fertilizer spreading mechanism 7, thereby driving the opening and closing mechanism 6 and the fertilizer spreading mechanism 7 hydraulically. The hydraulic oil level and temperature gauge 47 observes the oil temperature and level in the oil tank 43. The radiator 46 cools the returned hydraulic oil and then returns it to the oil tank 43.

[0039] Furthermore, a ball valve switch is installed on the oil outlet pipe of the fuel tank 43. A clutch 8 is bolted to the tricycle body 1. The output end of the clutch 8 is connected to the input shaft of the gear pump 42. A transmission wheel 9 is fixedly sleeved on both the input end of the clutch 8 and the output shaft of the gasoline engine 41. Two B-type belts 10 are sleeved between the transmission wheels 9. Two fixing plates 11 are bolted to the tricycle body 1 between the gear pump 42 and the gasoline engine 41. A tensioning wheel 12 is provided between the two fixing plates 11. The tensioning wheel 12 is tightly pressed against the top of the downward belt of the B-type belt 10. An adjusting shaft 13 is provided in the inner cavity of the tensioning wheel 12. A bearing 14 is installed between the outer wall of the adjusting shaft 13 and the inner wall of the tensioning wheel 12. An adjusting groove 16 is opened on the fixing plate 11. Both ends of the adjusting shaft 13 pass through the adjusting groove 16 and are threaded with locking nuts 15. The locking nuts 15 are tightly pressed against the fixing plate 11.

[0040] Through the above technical solution, the gasoline engine 41 drives the input end of the clutch 8 through the transmission wheel 9 and the B-type belt 10, and the output end of the clutch 8 drives the gear pump 42 to operate. Thus, when the gasoline engine 41 is being maintained, the clutch 8 can be disengaged, thereby preventing the gear pump 42 from rotating and facilitating the maintenance of the gasoline engine 41. At the same time, by loosening the locking nut 15, the adjusting shaft 13 can slide along the adjusting groove 16 to adjust the position of the tension wheel 12, which tightens the B-type belt 10. Then, the locking nut 15 is tightened to ensure the tautness of the B-type belt 10 and facilitate transmission.

[0041] Furthermore, the opening and closing mechanism 6 includes a discharge port 61. The bottom of the storage box 3 near the mounting plate 5 has a discharge port 61. The top inner wall of the discharge port 61 is hinged to an opening and closing door 62. The outer wall of the opening and closing door 62 is rotatably connected to the output rod of the opening and closing hydraulic cylinder 64 via a pin. A support rod 63 is fixedly installed on the outer wall of the mounting plate 5. The support rod 63 is hinged to the top of the opening and closing hydraulic cylinder 64. The inlet end of the opening and closing hydraulic cylinder 64 is connected to an outlet end of a multi-way valve 44 via an oil pipe. The outlet end of the opening and closing hydraulic cylinder 64 is connected to a return oil port of the oil tank 43 via an oil pipe. The bottom of the inner cavity of the storage box 3 is a square platform structure that is larger at the top and smaller at the bottom.

[0042] Through the above technical solution, the multi-way valve 44 controls the oil circuit of the opening and closing hydraulic cylinder 64, thereby enabling the opening and closing hydraulic cylinder 64 to extend and retract, thereby driving the opening and closing of the opening and closing door 62.

[0043] Furthermore, the opening and closing door 62 includes a top door 621 and a bottom door 622. The top of the top door 621 is connected to the top of the inner cavity of the discharge port 61 via a hinge, and the bottom of the top door 621 is connected to the bottom door 622 via a hinge. The outer wall of the top door 621 is hinged to the output rod of the opening and closing hydraulic cylinder 64. A second connecting plate 624 is fixedly installed on the side of the top door 621 away from the opening and closing hydraulic cylinder 64, and a first connecting plate 623 is fixedly installed on the side of the bottom door 622 away from the top door. Pin holes are opened on the first connecting plate 623 and the second connecting plate 624.

[0044] With the above technical solution, when applying compound fertilizer and relatively dry or granular fertilizer, the hydraulic cylinder 64 drives the top door 621 to open and close. The bottom door 622 is suspended at the bottom of the top door 621 under gravity. When the fertilizer passes through, it is scraped flat by the bottom door 622 to ensure uniform output. When applying wet fertilizers such as farmyard manure and compost, the top door 621 is rotated to open to a horizontal state, and the bottom door 622 is rotated to fit against the bottom surface of the top door 621. The first connecting plate 623 and the second connecting plate 624 are aligned, and the bottom door 622 is fixed by the pin through the pin hole to prevent the wet fertilizer from sticking to the bottom door 622, making it easier for the fertilizer to be pushed out by the feeding rod 74.

[0045] Furthermore, the fertilizer spreading mechanism 7 includes a feeding shaft 71, with the feeding shaft 71 rotatably sleeved between both ends of the mounting frame 2. Feeding sprockets 72 are fixedly sleeved at both ends of the feeding shaft 71, and a feeding chain 73 is sleeved between the feeding sprockets 72 on the two feeding shafts 71. The upper section of the feeding chain 73 penetrates the bottom plate of the storage box 3. A feeding rod 74 is fixedly installed on the feeding chain 73. A feeding hydraulic motor 75 is fixedly installed on the outer wall of the mounting plate 5. A transmission sprocket is sleeved between the output shaft of the feeding hydraulic motor 75 and one end of the feeding shaft 71, and a transmission chain is sleeved between the transmission sprockets. A feeding hydraulic motor 75 is fixedly installed on the mounting plate 5. Two hydraulic motors 76 for spinning discs are provided. The output shaft of the hydraulic motors 76 is connected to a spinning disc 77. The inlet end of the material feeding hydraulic motor 75 is connected to one outlet end of the multi-way valve 44 through an oil pipe. The outlet end of the material feeding hydraulic motor 75 is connected to the inlet end of the spinning disc hydraulic motor 76 through an oil pipe. The outlet end of the spinning disc hydraulic motor 76 is connected to the inlet end of the radiator 46 through an oil pipe. An adjusting sleeve 78 is fixedly installed on the top of the spinning disc 77. The adjusting sleeve 78 is fitted onto the output shaft of the spinning disc hydraulic motor 76, and a locking bolt is installed on the adjusting sleeve 78. A rubber bridge pad is installed at the output end of the spinning disc hydraulic motor 76.

[0046] Through the above technical solution, the oil circuit of the feeding hydraulic motor 75 is controlled by the multi-way valve 44. The feeding hydraulic motor 75 drives the feeding shaft 71 to rotate through the transmission sprocket and transmission chain. The feeding shaft 71 drives the feeding sprocket 72 to rotate, thereby causing the feeding chain 73 to rotate. When the feeding chain 73 rotates, the waste material in the storage box 3 is pushed out and dropped from the discharge port 61. At the same time, the return oil of the feeding hydraulic motor 75 drives the slinging disc hydraulic motor 76. The slinging disc hydraulic motor 76 drives the slinging disc 77 to rotate, thereby breaking up the dropped waste material and throwing it evenly onto the planting area to achieve uniform fertilizer application. Meanwhile, the height of the slinging disc 77 is adjusted by sliding the adjusting sleeve 78 on the output shaft of the hydraulic motor 76, and then locked by the locking bolt, thereby achieving the adjustment of the height of the slinging disc 77. By changing the throwing height, the higher the height when the fertilizer falls, the wider the final fall width, and vice versa, to meet the needs of different fertilizer application widths.

[0047] Furthermore, multiple lever plates 79 are fixedly welded to the top of the spinning disc 77. The angle between the lever plates 79 and the top of the spinning disc 77 is 30°. A material distribution plate 17 is installed at the bottom of the mounting plate 5 via a connecting rod. The material distribution plate 17 is located directly above the two spinning discs 77. The material distribution plate 17 has an L-shaped structure, and the side of the material distribution plate 17 facing the material distribution rod 74 has a triangular structure. A sliding groove 711 is opened inside the end of the mounting bracket 2 near the mounting plate 5. A slider 712 is slidably engaged in the sliding groove 711. The end face of the material distribution shaft 71 passes through the sliding groove 711 and is rotatably sleeved on the slider 712. An adjusting screw 713 is sleeved on the mounting plate 5 via a threaded structure. The end face of the adjusting screw 713 is rotatably engaged with the slider 712.

[0048] Through the above technical solution, the setting of the material distribution plate 17 facilitates the separation of fertilizer, avoids fertilizer accumulation in the middle, and causes fertilizer to fall to both sides. When the swivel plate 77 rotates, the dispensing plate 79 scatters the fertilizer to all sides. By rotating the adjusting screw 13, the slider 712 is pushed to slide along the slide groove 711, and the position of the dispensing shaft 71 at the mounting plate 5 is adjusted, thereby tightening the dispensing chain 73 and maintaining stable transmission.

[0049] Furthermore, the tricycle body 1 of the present invention has a narrow width, making it suitable for fertilizing sheds, farms, and grassland slopes. It can also spread substances such as salt grains when melting snow on roads. In normal times, the storage box 3 can also transport fruits and vegetables, realizing multiple functions in one machine.

[0050] Working principle: The storage bin 3 can store dry and wet fertilizers such as chemical fertilizers, granular fertilizers, and compost. The tricycle 1 travels along the greenhouse planting area. The gasoline engine 41 drives the gear pump 42, which delivers hydraulic oil from the oil tank 43 to the multi-way valve 44. The multi-way valve 44 controls the oil circuit of the opening / closing mechanism 6 and the fertilizer spreading mechanism 7, thus hydraulically driving the opening / closing mechanism 6 and the fertilizer spreading mechanism 7. The multi-way valve 44 controls the oil circuit connected to the opening / closing hydraulic cylinder 64, causing the opening / closing hydraulic cylinder 64 to extend and retract, driving the opening / closing door 62 to open and close. When the opening / closing door 62 is open, the multi-way valve 44 controls the oil circuit of the material-dispensing hydraulic motor 75. The material-dispensing hydraulic motor 75 drives the material-dispensing shaft 71 to rotate via the transmission sprocket and transmission chain. The material-dispensing shaft 71 drives the material-dispensing sprocket. Rotation of 72 causes the feeding chain 73 to rotate. When the feeding chain 73 rotates, it pushes the waste material in the storage box 3 out of the outlet 61 and drops it. At the same time, the return oil of the feeding hydraulic motor 75 drives the slinging disc hydraulic motor 76, which drives the slinging disc 77 to rotate. The setting of the dividing plate 17 facilitates the separation of fertilizer and avoids fertilizer from accumulating in the middle, so that the fertilizer falls to both sides. When the slinging disc 77 rotates, the feeding plate 79 scatters the fertilizer in all directions, thereby breaking up the fallen waste material and evenly throwing it into the planting area to achieve uniform fertilizer distribution. By rotating the adjusting screw 13, the slider 712 is pushed to slide along the slide groove 711 to adjust the position of the feeding shaft 71 at the mounting plate 5, thereby tightening the feeding chain 73 and maintaining stable transmission.

[0051] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
