[0010] Preferably, four groups of the honeycomb mesh panels are provided, and the four groups of honeycomb mesh panels are stacked together, and the holes between the four groups of honeycomb mesh panels are staggered with each other.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] (1) The height of the push rod can be adjusted by providing a first push rod, a second push rod, a threaded rod, a sleeve and a threaded collar. The threaded rod and the sleeve can support the first push rod. The rotation of the threaded collar can control the threaded rod to extend outward or retract into the sleeve. The first push rod and the second push rod form a movable hinge connection. The first push rod can be flipped on one side of the second push rod to adjust the angle of the first push rod to change the height of the first push rod to adapt to people of different heights, thereby improving the flexibility of use.
[0013] (2) By providing a mounting frame, a counterweight box, a threaded column and a counterweight block, the balance of the rice harvester can be adjusted. The counterweight box can store multiple counterweight blocks, and the rotation of the threaded column can control the bottom end of the threaded column to press down the counterweight block to prevent the counterweight block from jumping due to bumps. By adjusting the number of counterweight blocks, the front and rear balance of the rice harvester can be controlled, so that the front part can be tilted with less force, and the control process is more labor-saving;
[0014] (3) The effect of sound insulation and noise reduction is achieved by providing a cover body, a ventilation window, a honeycomb mesh panel, sound-absorbing cotton and a docking pin. The distribution of the docking pins and the docking with the groove at the bottom end of the harvester frame make it easy to fix the cover body on the outside of the engine, and the sound-absorbing cotton covers the inside of the cover body, which can absorb sound waves and reduce noise. At the same time, four groups of honeycomb mesh panels are stacked together, and the holes between the four groups of honeycomb mesh panels are staggered. The violent vibration of the honeycomb mesh panels is used to absorb a large amount of sound energy, reducing the transmission of noise to the outside, thereby achieving the effect of sound insulation and noise reduction.
