Description

Technical Field

[0001] This utility model relates to the field of fertilizer applicator technology, and in particular to an easy-to-use electrically started fertilizer applicator. Background Technology

[0002] Backpack sprayers are lightweight plant protection machines that are carried directly on the operator's back and use a small gasoline engine to drive a liquid pump or fan to evenly spray liquid fertilizer, pesticides or granules from the fertilizer storage tank onto the crop surface. They are characterized by their small size, light weight and flexible transfer, and are widely applicable to fertilization, disease prevention and weeding operations in various scenarios such as fields, orchards and greenhouses.

[0003] For example, the Chinese utility model patent CN203424200U, entitled "A Backpack-Type Sprayer / Powderer," uses a traditional gasoline engine for its power unit. To start the machine, the user must first lower the entire unit and repeatedly pull the starting rope to ignite the gasoline engine.

[0004] However, the aforementioned existing technologies have revealed obvious defects in actual field operations: when users need to temporarily stop the machine and then restart it, the entire machine must be unloaded, stabilized on the ground, and then the starting rope pulled to start the engine, and the entire machine must be carried again. If the field is muddy or the row spacing is narrow, it is often necessary to carry the weight to the outside of the field to put it down. The whole process is time-consuming and laborious, especially inconvenient for older farmers. In addition, frequent starting and stopping can easily cause the starting rope to break and the oil bubbles to age, reducing the reliability of the entire machine. Utility Model Content

[0005] This invention addresses the problem that existing fertilizer applicators require the entire machine to be disassembled, stabilized, and the rope pulled for ignition before restarting, a process that is time-consuming and labor-intensive, and frequent starts and stops can easily cause the starting rope to break. The technical problem this invention aims to solve is to provide an electric start fertilizer applicator that is easy to use and can be started and stopped instantly.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: it includes a back seat, a fertilizer storage box, and a fertilizer applicator connected to the fertilizer storage box. The back seat is provided with a support base, and the fertilizer storage box is fixed on the support base. The fertilizer applicator is used to spray fertilizer from the fertilizer storage box. The fertilizer applicator includes an engine, which is located on the back seat and behind the support base. A control area is provided on the left side of the back seat. The control area is provided with a handle assembly for controlling the throttle and fertilizer applicator discharge. The control area is also provided with a shutdown switch for controlling the engine to stop. It also includes a starter motor, an electric start switch, a battery holder, and a battery pack. The starter motor is connected to the crankshaft of the engine. The electric start switch is fixed in the control area and is used to control the starter motor to start. The battery pack is pluggably fixed on the battery holder to provide power for starting the starter motor. The starter motor drives the crankshaft to rotate to start the engine.

[0007] A further preferred embodiment of this utility model is as follows: the support base is higher than the engine, the upper side of the support base is provided with a hanging port and threaded holes on both sides below the hanging port, the upper end of the battery holder is provided with a hook that hooks onto the hanging port, and the two sides of the battery holder extend connecting parts with through holes. The battery holder can be fixed to the support base by screws passing through the through holes and engaging with the threaded holes.

[0008] A further preferred embodiment of this utility model is as follows: the battery pack is connected to the starter motor via line one and to the electric start switch via line two, both of which are located on the left side of the engine.

[0009] A further preferred embodiment of this utility model is: the line consists of two sections, one section having a first plug-in socket and the other section having a second plug-in socket, the first plug-in socket and the second plug-in socket being electrically connected by plugging in each other.

[0010] A further preferred embodiment of this utility model is: the battery holder has a horizontal insertion port with an opening facing left, and the battery pack slides horizontally into the horizontal insertion port from the left side to be inserted and locked with the battery holder.

[0011] A further preferred embodiment of this utility model is as follows: a fixed seat extending towards the front of the back seat is provided on the left side of the support base, the first handle and the second handle are provided on the fixed seat, the fixed seat is provided with a mounting seat, the top of the mounting seat extends upward and tilts backward to form an extension, and the electric start switch is provided on the extension.

[0012] A further preferred embodiment of this utility model is as follows: the mounting base has a rear side wall, the ignition switch is located on the rear side wall, and the ignition switch is electrically connected to the igniter in the engine through a third line. The third line consists of two segments connected in series in a plug-in manner.

[0013] A further preferred embodiment of this utility model is that the plug point of the third line is located on the left side of the engine.

[0014] A further preferred embodiment of this utility model is that the insertion and removal operations of the battery pack, as well as the connection points of all electrical connection lines between the electric start switch, the engine, and the battery pack, are located on the left side of the entire machine.

[0015] Compared with existing technologies, this invention has the following advantages: By incorporating an electric start switch, battery holder, and removable battery pack, users no longer need to disassemble the entire machine or pull the starter rope during frequent starts and stops. They can simply press the electric start switch while carrying the machine to start the engine with a single button press, eliminating the cumbersome steps of disassembling, bottoming out, and pulling the rope. This significantly reduces labor intensity and time consumption, making it particularly suitable for quick restarts after short stops in the field, improving operational continuity and efficiency. Furthermore, this invention fixes the electric start switch in the control area, a design that aligns with users' existing operating habits, making operation more convenient and faster.

[0019] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0020] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0021] This embodiment mainly describes a user-friendly electrically started fertilizer applicator, as detailed below: like Figures 1 to 7 As shown, a convenient electrically started fertilizer applicator includes a back seat 4, a fertilizer storage tank 2, and a fertilizer applicator connected to the fertilizer storage tank. A support base 1 is provided on the back seat 4, and the fertilizer storage tank 2 is fixed on the support base 1. The fertilizer applicator is used to spray fertilizer from the fertilizer storage tank. The specific structure and working principle of the fertilizer applicator can be found in Chinese Utility Model Patent No. CN203424200U. The power unit, nozzle, and blower casing in that patent form the fertilizer applicator corresponding to this utility model. The power unit corresponds to the engine 3 of this utility model. The fertilizer applicator includes the engine 3, which is located on the back seat 4 and behind the support base 1. The support base 1 is higher than the engine 3. This structure makes the center of gravity of the whole machine stable, which makes it easy for the operator to maintain balance when carrying it. At the same time, the high position design of the support base 1 makes the engine 3 protrude from the support base and form a natural installation space with the upper side of the support base 1. The left side of the backrest 4 is equipped with a control area, which includes a handle assembly 5 for controlling the throttle and the amount of fertilizer discharged from the fertilizer applicator. The control area also includes an engine shutdown switch 13. The operator can flexibly adjust the engine fuel intake via the handle assembly 5 to control the fertilizer applicator's output, achieving precise fertilization and improving operational efficiency.

[0022] The improvement of this utility model lies in the addition of an electric starting device, which includes a starter motor, an electric start switch 6, a battery holder 7, and a battery pack 8. The starter motor is connected to the crankshaft of the engine 3, specifically through: a direct connection between the motor output shaft and the engine crankshaft; a gear transmission connection between the motor output shaft and the engine crankshaft; or a synchronous belt transmission connection between the motor output shaft and the engine crankshaft. The electric start switch 6 is fixed in the control area and is used to control the operation of the starter motor, eliminating the need for the operator to pull a rope to start the engine, greatly simplifying the starting process. The battery holder 7 is fixed to the support base 1, and the battery pack 8 is detachably fixed to the battery holder 7, providing the power required for starting the starter motor. When the start switch is pressed, the starter motor operates under the power of the battery pack 8, directly driving the crankshaft of the engine 3 to rotate. The flywheel fixed to the crankshaft rotates synchronously, and the magnet on the flywheel, during rotation, interacts with the ignition magneto fixed to the engine 3, cutting magnetic lines of force. This magnetic change induces a current in the coil inside the ignition. This current is delivered to the spark plug of the engine 3, ultimately generating an electric spark to ignite the air-fuel mixture, thus reliably starting the engine 3. This electric start system achieves "instant start," completely eliminating the tedious steps of unloading, bottoming out, and pulling the rope, significantly reducing labor intensity and improving work efficiency. It completely solves the inconvenience and component damage problems of traditional manual starters in frequent start-stop scenarios, and is particularly suitable for quick restarts in muddy fields or narrow rows, significantly reducing the operator's labor intensity.

[0023] Specifically, the existing support base 1 has a pre-drilled hanging opening 101 and threaded holes on both sides below the hanging opening 101. This invention uses the existing hanging opening 101 and threaded holes to install the battery holder 7. The upper end of the battery holder 7 has hooks 701 that can be hooked onto the hanging opening 101. Connecting portions 702 with through holes 704 extend from both sides of the battery holder 7, allowing the battery holder 7 to be initially positioned using the hooks 701, and then screws are used to pass through the through holes 704 and engage with the threaded holes on the support base 1 for final tightening. This installation method is not only robust and reliable, effectively resisting vibration, but also achieves the installation and fixation of the battery holder 7 through the original threaded holes and hanging opening 101, eliminating the need to drill additional holes in the support base 1. This ingenious design also improves the convenience of the fertilizer applicator.

[0024] like Figure 2 , Figure 3 and Figure 4 As shown, battery pack 8 is connected to the starter motor via line 9, and battery pack 8 is electrically connected to the electric start switch 6 via line 10. Both line 9 and line 10 are located on the left side of engine 3. This method of concentrating the main power lines on one side makes the wiring clear and neat, avoiding the entanglement problems caused by wiring on both sides.

[0025] Specifically, line 9 consists of two sections, one with connector 901 and the other with connector 902. Connectors 901 and 902 are plugged into each other to transmit current. When the engine 3 needs maintenance or replacement, simply disconnect connectors 901 and 902 to quickly separate the battery pack 8 from the engine 3, avoiding wire tangling and pulling. This protects the connectors and facilitates disassembly and maintenance of the entire machine. It also simplifies on-site wiring and maintenance, allowing one person to complete the task by hand without tools, thus improving field maintainability.

[0026] like Figure 6 As shown, the battery holder 7 has a horizontal insertion port 703 with the opening facing left. The battery pack 8 slides horizontally into the horizontal insertion port 703 from the left side and is inserted and locked with the battery holder 7. This design allows the user to "blindly insert" the battery while carrying it on their back, without having to remove the device for visual inspection. The installation and removal can be completed in one step. The sliding rail insertion makes the battery pack 8 and the holder body form a three-sided limit. The greater the vibration in the field, the tighter the connection becomes, preventing instantaneous power failure caused by jumping and shaking, and ensuring that the electric start is always online.

[0027] like Figure 3As shown, the support base 1 has a fixed base 501 extending towards the front of the back seat 4 on its left side. The handle assembly 5 includes a first handle for controlling the throttle and a second handle for controlling the fertilizer applicator's discharge. The first handle 502 and the second handle 503 are mounted on the fixed base 501. The fixed base 501 also has a mounting base 11, the top of which extends upward and tilts backward to form an extension 12. The electric start switch 6 is mounted on this extension 12. This layout ensures that all control elements, including the electric start switch 6, are concentrated within the operator's reach. The backward-tilting extension 12 makes the switch position conspicuous and easy to press, while effectively preventing accidental activation, thus improving the safety and convenience of operation.

[0028] like Figure 2 As shown, in the prior art, the mounting base 501 has a rear side wall, on which an ignition switch 13 is installed. Since the ignition switch 13 is electrically connected to the igniter inside the engine 3, and users are accustomed to the location of the ignition switch 13 after long-term use of the fertilizer applicator, this utility model patent retains the user-familiar original location of the ignition switch 13 to avoid the user being unable to find it in case of sudden abnormalities or when an emergency shutdown is needed after work. The ignition switch 13 is electrically connected to the engine 3 via a third line 14, which consists of two sections connected in series in a plug-and-play manner. When the engine 3 needs to be removed for maintenance due to an abnormality, simply unplugging the connector instantly separates the ignition switch 13 from the engine 3, preventing the entire wiring harness from being pulled apart while moving with the engine 3, thus protecting the wiring and shortening disassembly time.

[0029] Specifically, the connector of line 3 14 is also located on the left side of engine 3. This brings all the main electrical connectors, including line 1 9, line 2 10, and line 3 14, to the same side of the machine, forming a clear maintenance area. This greatly facilitates the operator in quickly checking, maintaining, and installing the electrical connections of the entire machine, avoiding the difficulties in maintenance and installation that may result from scattered and messy wiring.

[0030] In this design, the insertion and removal of the battery pack 8, as well as the connection points of all electrical connection lines between the electric start switch 6, the engine 3, and the battery pack 8, are all located on the left side of the machine. All lines, including line 1 9, line 2 10, and line 3 14, are located on the left side of the machine. This arrangement is both ergonomic and convenient for installation. When disassembling or assembling the fertilizer applicator, the user can connect all the lines and install the battery pack 8 on the left side without having to move the machine back and forth, which greatly improves the efficiency of disassembling or installing the fertilizer applicator.

[0031] This utility model of fertilizer applicator can be used not only for fertilization, but also for spraying pesticides in the field to achieve the purpose of pest and weed control.
