Description

Technical Field

[0001] The present invention relates to the technical field of leaf blowers, in particular to an operational leaf blower. Background Art

[0002] A leaf blower is a garden or sanitation equipment used to quickly clean up fallen leaves, dust and other debris. It uses high-speed airflow to blow ground debris to a designated area and is widely used in parks, streets, campuses, courtyards and other scenes.

[0003] However, existing leaf blowers have the following shortcomings:

[0004] Leaf blowers in the existing technology generally adopt a directional air outlet design, which has significant limitations. Operators need to frequently adjust their walking path to aim at fallen leaves during operation, resulting in a significant reduction in operating efficiency. In addition, the strong airflow in a single direction can easily stir up ground dust during the blowing process, forming dust pollution with excessive PM2.5 concentration, which not only endangers the respiratory health of operators, but also causes secondary pollution to the surrounding environment. Faced with the humid environment after rain, the cleaning efficiency of traditional leaf blowers is further weakened. The wet fallen leaves form a strong adhesion to the ground due to water infiltration, making it difficult to effectively blow away the fallen leaves. A large amount of leaves remain on the ground, seriously affecting the cleaning effect and operation progress.

[0005] Therefore, we propose a work-type leaf blower to solve the problems raised above. Summary of the Invention

[0022] In the present invention, by integrating the four core mechanisms of power, blowing, steering and heat source recovery, an efficient and coordinated operating system is constructed. The steering mechanism uses the connecting pipe as the pivot, and the gear plate is firmly fixed by the bottom connecting ring and the clamping ring. The motor drives the gear and the gear plate to precisely engage, so that the air outlet pipe can rotate freely in the horizontal direction of 180 degrees in the whole range, flexibly adapting to complex and changeable working environments, and significantly improving work efficiency. At the same time, the electric push rod connects the metal plate and the U-shaped frame, and accurately controls the vertical rotation of the air outlet pipe by 17 degrees up and down to meet the directional air supply needs in different scenarios. The heat source recovery mechanism plays an energy-saving role. It has dual purification effects. It efficiently collects the waste heat generated by the operation of the equipment through the air inlet hood, transports it to the air outlet hood through the air inlet pipe, and then is sucked in by the blower mechanism. The hot air is then discharged from the air outlet duct in a directed manner. The hot air acts on the ground, which can not only quickly dry the humid area, but also effectively blow away the wet fallen leaves stuck to the ground. In this process, the negative charges released by the positive and negative ion generators attract the positive charges on the surface of the dust, causing the dust to gain weight and settle, which not only avoids dust harming the respiratory health of the operators, but also eliminates the problem of secondary pollution. The two major mechanisms of steering and heat source recovery work together to achieve precise wind control and efficient energy saving. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] Example 1, as Figure 1 and Figure 2 As shown: A work-type leaf blower includes a power mechanism 100, a blower mechanism 200, a steering mechanism 300 and a heat source recovery mechanism 400. The power mechanism 100 provides a power source for the entire device, and the power mechanism 100 drives the blower mechanism 200 to operate, thereby generating wind force. The steering mechanism 300 is connected to the blower mechanism 200 and can change the direction of the wind force generated by the blower mechanism 200. The heat source recovery mechanism 400 recovers the heat source generated by the power mechanism 100 and transmits it to the blower mechanism 200.

[0039] like Figures 9-11 As shown, the steering mechanism 300 includes a connecting pipe 301, a connecting ring 302 is sleeved on the bottom of the connecting pipe 301, a snap ring 303 is installed on the bottom of the connecting ring 302, a gear plate 304 is movably embedded in the inner surface wall of the snap ring 303, two connecting plates 305 are welded to the bottom of the gear plate 304, an air outlet pipe 306 is installed at the bottom of the two connecting plates 305, a U-shaped frame 307 is welded to the top of the air outlet pipe 306, a metal plate 308 is welded to the top of the gear plate 304, and the outer wall of the metal plate 308 An electric push rod 309 is installed on one side, and the output end of the electric push rod 309 is connected to the inner wall of the U-shaped frame 307. A lining plate 310 is welded to the top of the connecting ring 302, and a motor 311 is installed at the bottom of the lining plate 310. The output end of the motor 311 passes through the bottom of the connecting ring 302 and is fixedly sleeved with a gear 312. The gear 312 is engaged with the gear plate 304. Two limit switches 313 are installed on the top of the connecting ring 302, and a limit plate 314 is welded to the top of the gear plate 304.

[0040] like Figure 12 and Figure 13 As shown, the heat source recovery mechanism 400 includes an air inlet hood 401, the output end of the air inlet hood 401 is connected to the air inlet pipe 402, the output end of the air inlet pipe 402 is connected to the air outlet hood 403, and a positive and negative ion generator 404 is installed on one side of the outer wall of the air outlet hood 403, and the output end of the positive and negative ion generator 404 passes through one side of the outer wall of the air outlet hood 403.

[0041] In this embodiment, during the operation of the equipment, the steering mechanism 300 and the heat source recovery mechanism 400 work closely together to achieve the purpose of precise wind control and dehumidification and dust removal. In the steering mechanism 300, the motor 311 serves as the power source, driving the gear 312 to rotate continuously. Through precise engagement with the gear plate 304, the connecting plate 305 and the air outlet pipe 306 are driven to rotate 180 degrees in the horizontal direction. Whether it is an open area or a narrow space, the blowing direction can be adjusted as needed. At the same time, the electric push rod 309 pushes and pulls the U-shaped frame 307 through a telescopic action, which can accurately control the vertical pitch angle of the air outlet pipe 306 within the range of ±17 degrees, ensuring that the wind force can be directed to target areas at different heights and positions according to actual needs. To ensure safe operation, the limit switch 313 and the limit plate 314 cooperate with each other. When the gear plate 304 rotates to the preset angle, the limit plate 314 promptly triggers the limit switch 313, and the motor 311 is automatically powered off, effectively avoiding damage to the mechanism caused by over-travel rotation.

[0042] The heat source recovery mechanism 400 collects the high-temperature gas generated by the operation of the power mechanism 100 through the air inlet hood 401. These gases containing waste heat are transported to the air outlet hood 403 through the air inlet pipe 402. During this process, the positive and negative ion generator 404 continuously releases negative ions, giving the high-temperature gas a negative charge. At this time, in conjunction with the negative pressure generated by the rotation of the impeller 203 in the hair dryer mechanism 200, the negatively charged high-temperature gas is quickly sucked into the volute 201, and then flows along the connecting pipe 301 to the air outlet duct 306, and is finally discharged from the equipment. The discharged hot air can not only quickly dry the ground, effectively prevent wet fallen leaves from sticking, and improve cleaning efficiency, but also the negatively charged gas and the positively charged dust in the air attract each other, causing the dust to gain weight and settle, thereby avoiding dust from causing harm to the respiratory health of workers and eliminating the problem of secondary pollution.

A reversing valve 110 is provided on one side of the outer wall of each of the two reversing valves 110, and a control push rod 111 is provided on one side of the outer wall of each of the two reversing valves 110. A battery assembly 112 is installed on the top of the frame 101, and mudguards 113 are provided on both sides of the outer wall of the frame 101. A pedal 114 is provided between the opposite sides of the two mudguards 113. A protective pad 115 is provided on one side of the outer wall of the bracket 104, and two grips 116 are installed on the top of the bracket 104. A starting switch 117, an electric push rod control rocker 118, a motor control rocker 119 and a clutch switch 120 are respectively provided on the top of the bracket 104. A tool box 121 is installed on one side of the outer wall of the frame 101, and a muffler 122 is provided at the exhaust end of the engine 107.

[0044] like Figure 7 and Figure 8As shown, the hair dryer mechanism 200 includes a vortex casing 201, a guard plate 202 is provided at the rear end of the vortex casing 201, an impeller 203 is movably inserted inside the vortex casing 201, an impeller pulley 204 is sleeved on the input end of the impeller 203, an impeller adapter wheel 205 and a first tension wheel 206 are movably inserted at the rear end of the vortex casing 201, an impeller belt 207 is transmission-connected between the impeller pulley 204 and the outer wall of the impeller adapter wheel 205, an adapter shaft 208 is fixedly inserted on the inner wall of the impeller adapter wheel 205, a clutch adapter wheel 210 is fixedly sleeved on the input end of the adapter shaft 208, an electromagnetic clutch 213 is provided at the output end of the engine 107, a clutch pulley 209 is provided at the output end of the electromagnetic clutch 213, and the clutch pulley 209 and the outer surface of the clutch adapter wheel 210 are connected. A clutch belt 212 is connected for transmission between the walls, a second tensioning wheel 211 is movably inserted on one side of the inner wall of the guard plate 202, an impeller fixing plate 214 is provided on one side of the outer wall of the volute 201, and a guard 215 is provided on the outer side of the impeller fixing plate 214. The bottom of the guard plate 202 is connected to the top of the frame 101 by bolts, and the input end of the connecting pipe 301 is connected to the output end of the volute 201 by bolts. The air inlet cover 401 is installed at the bottom of the frame 101, and the air outlet cover 403 is located at the air inlet of the hair dryer mechanism 200. The start switch 117 is electrically connected to the engine 107, the electric push rod control rocker 118 is electrically connected to the electric push rod 309, the motor control rocker 119 is electrically connected to the motor 311, and the clutch switch 120 is electrically connected to the electromagnetic clutch 213.

[0045] In this embodiment, the device is centered around a power mechanism 100, achieving complex functions through the coordinated operation of multiple mechanisms. Within the power mechanism 100, an engine 107 serves as the power source, transmitting power to two hydraulic pumps 108 via a transmission belt 109. The hydraulic pumps 108 draw hydraulic oil from a fuel tank 106, and through a reversing valve 110, cooperate with a control push rod 111 to precisely control the flow direction and pressure of the hydraulic oil, driving the rear wheels 102 to achieve forward, reverse, and steering movements. A battery assembly 112 supplies power to the electrical system, while fenders 113 and pedals 114 ensure operational safety. A handle 116 and various control switches are located on top of the bracket 104, making them convenient for operators to operate.

[0046] The blower mechanism 200 is driven by the power mechanism 100. The electromagnetic clutch 213 at the output end of the engine 107 is connected to the clutch pulley 209. The clutch switch 120 is activated, and the electromagnetic clutch 213 is engaged. When the engine 107 rotates, it drives the clutch pulley 209 to rotate. Under the transmission action of the clutch belt 212, the clutch adapter wheel 210 is driven to rotate. The power is transmitted to the impeller adapter wheel 205 through the adapter shaft 208, and then drives the impeller pulley 204 and the impeller 203 to rotate at high speed through the impeller belt 207. When the impeller 203 rotates, a negative pressure is formed in the volute 201, and the high-temperature gas purified by the heat source recovery mechanism 400 at the air outlet cover 403 is sucked in. The mixed air flow is discharged from the air outlet pipe 306 through the connecting pipe 301.

[0047] The steering mechanism 300 and the heat source recovery mechanism 400 work in sync, and the operator controls the motor 311 and the electric push rod 309 respectively through the motor control rocker 119 and the electric push rod control rocker 118.

[0048] The method of use and working principle of this device are as follows: First, the staff stands on the pedal 114 and can lean on the pad 115, then inserts the key into the start switch 117 to start the engine 107. When the engine 107 starts, the power is transmitted to the two hydraulic pumps 108 through the transmission belt 109. The hydraulic pumps 108 obtain hydraulic oil from the oil tank 106 and cooperate with the control push rod 111 through the reversing valve 110 to accurately control the flow direction and pressure of the hydraulic oil. When the control push rod 111 is pushed forward at the same time, the two pumps output oil flow in the same direction, and the flow rate increases with the angle. The two rear wheels 10 2 forward in the same direction, the speed increases with the flow rate, thereby driving the device forward. When the control push rods 111 are pulled backward at the same time, the two pumps output opposite oil flows, the flow rate increases with the angle, the two rear wheels 102 move backward in the same direction, the speed increases with the flow rate, and the device moves backward. When only one of the control push rods 111 is pushed, only one rear wheel 102 can be driven to rotate. With the cooperation of the front wheel 103, the device can be turned in place. The battery assembly 112 provides power for the electrical system. The mudguard 113 and the pedal 114 ensure operational safety. The handle 116 facilitates operator control.

[0049] When the leaf blowing operation is required, the clutch switch 120 is started, and the electromagnetic clutch 213 is attracted to the clutch pulley 209, which can drive the clutch pulley 209 to rotate. Under the transmission action of the clutch belt 212, the clutch adapter wheel 210 is driven to rotate, and the power is transmitted to the impeller adapter wheel 205 through the adapter shaft 208, and then the impeller pulley 204 and the impeller 203 are driven to rotate at high speed through the impeller belt 207. When the impeller 203 rotates, negative pressure is formed in the volute 201. At this time, the air inlet cover 401 collects the heat generated by the operation of the engine 107 and the hydraulic pump 108. The gas containing the residual heat is output through the air inlet pipe 402. The air is then sent to the air outlet hood 403. During this process, the positive and negative ion generator 404 continuously releases negative ions, giving the high-temperature gas a negative charge. At this time, in conjunction with the negative pressure generated by the rotation of the impeller 203 in the blower mechanism 200, the negatively charged high-temperature gas is quickly sucked into the volute 201, then flows along the connecting pipe 301 to the air outlet pipe 306, and is finally discharged from the equipment. The discharged hot air can not only quickly dry the ground, effectively prevent wet fallen leaves from sticking, and improve cleaning efficiency, but also the negatively charged gas and the positively charged dust in the air attract each other, causing the dust to increase in weight and settle, thereby avoiding the harm of dust to the respiratory health of workers and eliminating the problem of secondary pollution.

[0050] During the leaf blowing process, pushing the motor control rocker 119 to the left will start the motor 311 for forward output, and pushing the motor control rocker 119 to the right will start the motor 311 for reverse output. The motor 311 drives the gear 312 to rotate continuously, and through the precise engagement with the gear plate 304, the connecting plate 305 and the air outlet pipe 306 are driven to rotate 180 degrees in the horizontal direction. Whether it is an open area or a narrow space, the blowing direction can be adjusted as needed. At the same time, pushing the electric push rod control rocker 118 forward will press the electric push rod 309 downward, and pulling the electric push rod control rocker 118 backward will cause the electric push rod 309 to rotate horizontally. The rocker 118 and the electric push rod 309 will be lifted upward. The electric push rod 309 pushes and pulls the U-shaped frame 307 through the telescopic action, which can accurately control the vertical pitch angle of the air outlet 306 within the range of ±17°, ensuring that the wind force can be directed to target areas at different heights and positions according to actual needs. To ensure safe operation, the limit switch 313 and the limit plate 314 cooperate with each other. When the gear plate 304 rotates to the preset angle, the limit plate 314 triggers the limit switch 313 in time, and the motor 311 is automatically powered off, effectively avoiding damage to the mechanism caused by over-travel rotation.

[0051] In summary, the problems raised in the above background are solved.
