Mowing system
The power system transmits power to this rotating wheel through belt drive. The rotating wheel is connected to the cutting table part. The gear transmission box is installed in the cutting table. The circular cutting disc is connected to the cutting disc. Three cutting knives are evenly installed on the cutting table belt disc. The cutting table drives the circular cutting disc to rotate and cut at high speed. The cutting table is connected to the machine frame through these two connection points. The position of the upper connection can be changed. By changing the position of these two screws, the ground clearance of the cutting table can be adjusted appropriately to achieve the purpose of adjusting the height of the cutting stubble. This is the cutting table protective cover, which is connected to the frame. Its main function is to block the debris rolled up by the cutting knife during operation to avoid hurting the operator behind.
Operating system
Operating system, the above systems must be under the unified control of the operating system to complete various operations. The operating system is at the rear of the whole machine. All operations are completed on the transmission operating lever and the operating handle. The operating handle is not only the operator's armrest, but also has various operating handles installed on it. Here is the connection hole between the handle and the machine, which is divided into three connection holes: high, medium and low. The operating handle can be adjusted appropriately according to the height of the operator. On this side of the operating handle, a gearbox clutch handle is installed. The bottom of the handle is connected to a metal pull wire, and the other end of this pull wire is connected to the gearbox belt pulley introduced earlier. Therefore, the gearbox clutch handle can control the power transmission to the gearbox.
On the other side of the operating handle, a clutch handle of the cutting system is installed. Similarly, a metal pull wire is also connected to the bottom of this clutch handle, and its other end is connected to the belt pulley introduced earlier. Similarly: when the clutch handle is in the front position, the pull wire is tightened, the belt pulley is close to the belt, the power is connected, and the power is transmitted to the cutting table part through the belt; when the clutch handle is in the back position, the pull wire is loose, the belt pulley releases the power belt, and the power is disconnected, so this clutch handle can directly control the operation and stop of the cutting table.
This is the throttle control handle, which is also connected to the engine throttle through a metal cable. The throttle control handle has three position areas, namely the front, middle and back, corresponding to the three areas on the throttle. When the handle is in the last position, the throttle is closed. When the control handle is in the middle position, the throttle is moderate. Generally, when the engine is started, the handle is in the middle position. When the handle is pushed forward, the throttle gradually increases. The larger the throttle, the stronger the power output of the engine. The throttle handle position can be adjusted at any time when walking and harvesting to obtain the required power.
Let's take a look at the gearbox operating lever. It is connected to the gearbox and is actually the gear handle. The power from the engine must be converted through the gearbox before it can be output to the travel wheel. This lawn mower is designed with six forward gears and two reverse gears, which can be divided into high-speed gears and low-speed gears. Its position distribution is: when the handle is in the middle position at the bottom, it is in the neutral position and the gearbox has no power output; when the handle is moved to the left, the low-speed gear is selected, and when the handle is moved to the right, the high-speed gear is selected. The specific operation is as follows: first move the handle to the left once, and then move the handle to this position, then the low-speed first gear is selected. If the handle is moved to this position, the low-speed second gear is selected, which is the low-speed third gear here; if the handle is moved to the right once, and then the handle is moved to this position, the high-speed fourth gear is selected, and so on, this is the high-speed fifth gear, and this is the high-speed sixth gear. It can be seen that the following two positions are the switching positions of high-speed gear and low-speed gear. The position above is the reverse gear, which also has high speed and low speed. The selection method is the same as the forward gear. In normal operation, select the forward second gear. When the grass density is high, the harvesting resistance increases, so the forward low gear should be selected. In the transport state, the travel gear can be selected at any time as needed.
