The magnet 42 at the bottom of the connecting block has the same outer diameter as the top of the accelerator pedal 31 in the cab of the loader 3, and the magnet 42 and the top of the steel accelerator pedal 31 are attracted together. The two poles of the battery AG1 and the two ends of the charging socket CZ1 (when the battery AG1 is dead, plug the external 24V power charger into the jack of the charging socket CZ1 to charge the battery AG1) are connected via wires. These are then connected in series via the power switch S2 and the power input terminals of the wireless receiving display XS and the wireless remote control mechanism T1. The wireless receiving mechanism includes relays J1, J2, and J3 connected via circuit board wiring, and a wireless receiving circuit module T. The positive power input terminal 1 of the wireless receiving circuit module T is connected to the positive control power input terminals of two relays J2 and J3. The three power output terminals 13, 14, and 11 of the wireless receiving circuit module T are respectively connected to the positive power input terminals of two relays J2 and J3 and another relay J1. The negative power input terminal of another relay J1 and the negative power input terminals of two relays J2 and J3 are connected to the negative control power input terminal and the negative power input terminal 2 of the wireless receiving circuit module T.

[0018] Figure 1 、 2In , 3, and 4, the power output terminals 3, 4, 5, 6, 7, 8, 9, and 10 of the wireless receiving circuit module T are connected to the 2nd terminal and the power input terminals of the eight solenoid valves DC1, DC2, DC3, DC4, DC5, DC6, DC7, and DC8 via wires respectively; the control power input terminal and the normally open contact terminal of the relay J1 are connected to the two terminals of the loader's starting key power switch M via wires respectively; the power output terminal 12 and the 2nd terminal of the wireless receiving circuit module T are connected to the two terminals of the power switch of the loader's ignition solenoid valve DC via wires respectively; the two normally open contact terminals of the relays J2 and J3 are connected to the positive and negative and negative and positive and negative power input terminals of the electric push rod M1 via wires respectively. Power switches S1 and S2 are toggle-type power switches; relays J1, J2, and J3 are DC24V; battery AG1 is a 24V / 10Ah lithium battery; wireless transmitting circuit module T1 (wireless remote control mechanism T1) and wireless receiving circuit module T are finished 16-channel wireless transmitting and receiving module components, model APDC-16K.

Figure 3 、 4 In the present invention, all electronic components are existing mature products, and this application does not elaborate on their working principles.

[0019] Figure 1 、 2As shown in Figures 3 and 4, when the present invention is operated manually, the nut is removed, and then the connecting seat 45 at the upper end of the cylinder of the electric push rod M1 and the shaft 44 are separated. After separating the magnet 42 and the pedal 31, the throttle control mechanism can be removed. Subsequent operators can conveniently operate the loader normally without a clutch or gear by stepping on the accelerator pedal to load and unload cargo (the loader is an existing mature equipment, and its working principle is not described in detail in this application). When the present invention requires wireless control of the loader, the throttle control mechanism is installed, and after turning on the power switches S1 and S2, the relevant mechanisms are powered and operated. The camera SX will transmit the images of the loader's on-site operation to the wireless receiving display screen XS for display (two sets of cameras can be installed, with the rear camera's camera facing the rear end of the vehicle body. The wireless receiving display screen XS will display the images transmitted by the two sets of cameras on a split screen, allowing workers to wirelessly control the loader's working mode more safely and conveniently). In this way, workers at a certain distance (generally within 100 meters) can issue different control instructions through the handheld wireless remote control mechanism T1, thereby controlling the loader's different working modes. When the staff member presses the 9th button of the wireless remote control mechanism T1 for the first time with his finger, the wireless remote control mechanism T1 transmits the 9th wireless closing signal. After the wireless receiving circuit module T receives it, its 11th pin outputs a high level. In this way, the relay J1 is energized and its control power input terminal and normally open contact terminal are closed. The two terminals of the key power switch M on the loader will be connected, and the starting motor on the loader will start the loader engine; after the engine is started, when the staff member presses the 9th button of the wireless remote control mechanism T1 again with his finger, the wireless remote control mechanism T1 transmits the 9th wireless opening signal. After the wireless receiving circuit module T receives it, its 11th pin stops being high. In this way, the relay J1 loses power and no longer attracts its control power input terminal and normally open contact terminal, and then the two terminals of the key power switch M on the loader will be open, and the starting motor on the loader will also stop working. When the work is completed, when the staff presses the 10th button of the wireless remote control mechanism T1 for the first time with their finger, the wireless remote control mechanism T1 transmits the 10th wireless closing signal. After the wireless receiving circuit module T receives it, its 12th pin outputs a high level. In this way, the flameout solenoid valve DC on the loader will be energized to close the oil circuit of the engine, and then the engine will stop working; when the staff presses the 10th button of the wireless remote control mechanism T1 for the second time with their finger, the wireless remote control mechanism T1 transmits the 10th wireless opening signal. After the wireless receiving circuit module T receives it, its 12th pin stops outputting a high level. In this way, the flameout solenoid valve DC on the loader will lose power and no longer close the oil circuit of the engine, and the engine can start normally afterwards.

[0020] Figure 1 、 2As shown in Figures 3 and 4, when the staff member presses the first or second button of the wireless remote control mechanism T1 for the first time with his finger, the wireless remote control mechanism T1 transmits the first or second wireless closing signal. After receiving the signal, the 3rd or 4th pin of the wireless receiving circuit module T outputs a high level. In this way, the solenoid valve DC1 or the solenoid valve DC2 is energized to open the working valve core. The high-pressure hydraulic oil output from the oil outlet pipe of the loader's hydraulic oil pump 3 flows through the oil outlet pipe and the first oil inlet and return port of the solenoid valve DC1 or the solenoid valve DC2, the inlet of the solenoid valve DC1 or the solenoid valve DC2, and the oil inlet and outlet of the left or right end of the loader's steering hydraulic motor respectively into the steering hydraulic motor (the hydraulic oil returning from the inlet and outlet of the right or left end of the steering hydraulic motor flows through the second oil inlet and return port of the solenoid valve DC2 or the solenoid valve DC1 and the hydraulic oil pump return pipe and flows back into the hydraulic oil pump for recycling). Then, the hydraulic motor drives the steering wheel of the loader to turn right or left through relevant mechanisms, and the loader turns right or left to move forward or backward. When the staff presses the first or second button of the wireless remote control mechanism T1 again with their fingers, the wireless remote control mechanism T1 transmits the first or second wireless open-circuit signal. After the wireless receiving circuit module T receives it, its 3rd or 4th pin stops outputting a high level. In this way, the solenoid valve DC1 or the solenoid valve DC2 will lose power and the valve core will be closed, and the loader 3 will no longer make a turning action. When the staff presses the 3rd or 4th button of the wireless remote control mechanism T1 for the first time with their finger, the wireless remote control mechanism T1 transmits the 3rd or 4th wireless closed signal. After the wireless receiving circuit module T receives it, its 5th or 6th pin outputs a high level. In this way, the solenoid valve DC3 or the solenoid valve DC4 will be energized to open the working valve core, and the high-pressure hydraulic oil output from the oil outlet pipe of the hydraulic oil pump of the loader 3 passes through the oil outlet pipe and the first oil inlet and return port of the solenoid valve DC3 or the solenoid valve DC4, the inlet of the solenoid valve DC3 or the solenoid valve DC4, and the oil inlet and outlet of the front or rear side of the loader's driving hydraulic motor respectively into the steering drive hydraulic motor (the hydraulic oil returning from the inlet and outlet of the rear or front side of the driving hydraulic motor passes through the second oil inlet and return port of the solenoid valve DC4 or the solenoid valve DC3 and the hydraulic oil pump return pipe and returns to the hydraulic oil pump for recycling). Then, the driving hydraulic motor drives the loader 3 forward or backward through the relevant mechanisms. When the staff presses the 3rd or 4th button of the wireless remote control mechanism T1 again with their fingers, the wireless remote control mechanism T1 transmits the 3rd or 4th wireless open-circuit signal. After the wireless receiving circuit module T receives it, its 5th or 6th pin stops outputting a high level. In this way, the solenoid valve DC3 or the solenoid valve DC4 will lose power and the valve core will be closed, and the loader 3 will no longer move forward or backward.When the staff presses the 5th or 6th button of the wireless remote control mechanism T1 for the first time with their finger, the wireless remote control mechanism T1 transmits the 5th or 6th wireless closed signal. After the wireless receiving circuit module T receives it, its 7th or 8th pin outputs a high level. In this way, the solenoid valve DC5 or the solenoid valve DC6 will be energized to open the working valve core, and the high-pressure hydraulic oil output from the oil outlet pipe of the loader's hydraulic oil pump passes through the oil outlet pipe and the first oil inlet and return port of the solenoid valve DC5 or the solenoid valve DC6, and the inlet of the solenoid valve DC5 or the solenoid valve DC6, and the upper or lower end oil inlet and outlet of the cylinder barrel of the loader's lifting cylinder respectively enters the upper end or lower end of the cylinder barrel of the lifting cylinder (the hydraulic oil returning from the oil inlet and outlet at the lower or upper side end of the cylinder barrel of the lifting cylinder passes through the second oil inlet and return port of the solenoid valve DC6 or the solenoid valve DC5 and the hydraulic oil pump return pipe and returns to the hydraulic oil pump for recycling). Then, the lifting cylinder controls the bucket to descend or ascend through the relevant mechanism. When the staff presses the 5th or 6th button of the wireless remote control mechanism T1 again with their fingers, the wireless remote control mechanism T1 transmits the 5th or 6th wireless open-circuit signal. After the wireless receiving circuit module T receives it, its 7th or 8th pin stops outputting a high level. In this way, the solenoid valve DC5 or the solenoid valve DC6 will lose power and the valve core will be closed, and the bucket of the loader 3 will no longer descend or ascend. When the staff presses the 7th or 8th button of the wireless remote control mechanism T1 for the first time with their fingers, the wireless remote control mechanism T1 transmits the 7th or 8th wireless closed signal. After the wireless receiving circuit module T receives the signal, its 9th or 10th pin outputs a high level. In this way, the solenoid valve DC7 or the solenoid valve DC8 will be energized to open the working valve core, and the high-pressure hydraulic oil output from the oil outlet pipe of the loader 3 hydraulic oil pump passes through the oil outlet pipe and the first oil inlet and return port of the solenoid valve DC7 or the solenoid valve DC8, the inlet of the solenoid valve DC7 or the solenoid valve DC8, and the front or rear end oil inlet and outlet of the cylinder barrel of the loader bucket cylinder respectively enters the front or rear end of the cylinder barrel of the bucket cylinder (the hydraulic oil returning from the inlet and outlet at the rear or front side end of the cylinder barrel of the bucket cylinder passes through the second oil inlet and return port of the solenoid valve DC8 or the solenoid valve DC7 and the hydraulic oil pump return pipe and returns to the hydraulic oil pump for recycling). Then, the bucket cylinder controls the axial, backward or forward rotation angle of the bucket (loading or unloading) through the relevant mechanism. When the staff member presses the 7th or 8th button of the wireless remote control mechanism T1 again with his finger, the wireless remote control mechanism T1 transmits the 7th or 8th wireless open-circuit signal. After the wireless receiving circuit module T receives it, its 9th or 10th pin stops outputting a high level. In this way, the solenoid valve DC7 or the solenoid valve DC8 loses power and the valve core is closed, and the bucket of the loader 3 no longer generates forward and backward (i.e., clockwise or counterclockwise) rotation angle action.

[0021] Figure 1 、 2As shown in Figures 3 and 4, when the staff needs to control the loader 3 to travel faster or slower, they press the 11th or 12th button of the wireless remote control mechanism T1 for the first time with their finger. The wireless remote control mechanism T1 transmits the 11th or 12th wireless closing signal. After the wireless receiving circuit module T receives the signal, its 13th or 14th pin outputs a high level. In this way, the relay J2 or J3 is energized to attract its control power input terminal and the normally open contact terminal to close. Then, the positive and negative or negative and positive power input terminals of the electric push rod M1 are energized (after the positive and negative power input terminals of the electric push rod M1 are energized, its push column descends, and after the negative and positive power input terminals of the electric push rod M1 are energized, its push column ascends. The magnet has a strong suction force, and the two will not separate when the accelerator pedal is driven upward). The push column of the electric push rod M1 pushes the accelerator pedal 31 downward or upward through the magnet and the connecting block 41. In this way, the throttle of the loader will be relatively larger or smaller, and the loader will perform loading operations at a faster or slower speed. When the staff member presses the 11th or 12th button of the wireless remote control mechanism T1 again with his finger, the wireless remote control mechanism T1 transmits the 11th or 12th wireless open-circuit signal. After the wireless receiving circuit module T receives it, its 13th or 14th pin stops outputting a high level. In this way, the relay J2 or J3 loses power and no longer attracts the control power input terminal and the normally open contact terminal to open the circuit. The accelerator pedal 31 no longer drops or rises in height, and the loader maintains the current speed to perform loading operations. Through the above, the new model makes it convenient to remove the throttle control mechanism, so that the staff member can manually control the working mode of the loader. After the throttle control mechanism is installed, the working mode of the loader can be wirelessly controlled by the wireless remote control mechanism and the wireless receiving mechanism. The new model brings convenience to the staff member, reduces the workload, and is relatively more flexible in application.
