Embodiment Construction
[0019] The present invention will be further described below in conjunction with drawings and embodiments.
[0020] Such as Figure 1 ~ Figure 4 Shown, the present invention comprises flat belt 1, engine pulley 2, two cutter pulleys and tensioner mechanism 4, prevents that flat belt slip-off mechanism 5 is arranged on the flat belt between engine pulley 2 and the first cutter pulley 31 1 outside, the outside of two cutter belt pulleys is respectively provided with retaining belt cover 6. The flat belt 1 walks around the engine pulley 2 and the two cutter pulleys in turn, and the tensioner mechanism 4 is positioned outside the engine pulley 2 and the second cutter pulley 32 and leans against the flat belt 1 .
[0021] The mechanism 5 for preventing the flat belt from falling out of groove comprises two belt brackets 51 and an L-shaped base 52. The belt bracket 51 is in a U-shape toppled over. The vertical fixed welding is connected, and the L-shaped base 52 is made of angle s...

The invention discloses a mowing table transmission device of a pedestrian-controlled lawn mower. The mowing table transmission device comprises a flat belt, an engine belt pulley, two cutter belt pulleys and a tensioning wheel mechanism, wherein a mechanism for preventing the flat belt from falling out of grooves is arranged on the outer side of the flat belt between the engine belt pulley and the other cutter belt pulley, and belt blocking hoods are respectively arranged on the outer sides of the two cutter belt pulleys; the upper and lower sides of the flat belt are located between the upper and lower horizontal rods of a belt support rack; the groove width of the engine belt pulley is larger than the width of the flat belt. The mowing table transmission device has the advantages that the device is simple in structure, low in cost and high in use efficiency; when the terrain clearance of a mowing table is adjusted, the flat belt can move vertically to adapt to the height change of the mowing table, and the service life of the flat belt is prolonged; the mechanism for preventing the flat belt from falling out of the grooves uses the belt support rack to prevent the flat belt from falling out of the grooves and can drive the flat belt to move up and down so as to adjust the terrain clearance of the mowing table.
Description
technical field [0001] The invention relates to a double-knife transmission device of a lawn mower, in particular to a double-cutter transmission device of a lawn mower capable of moving a flat belt up and down in a wheel groove of an engine pulley, and belongs to the technical field of garden machinery. Background technique [0002] When the lawn mower is working, the operator needs to adjust the ground height of the lawn mower mower according to the lawn conditions. Since the engine of the lawn mower is fixed on the frame, the height of the engine pulley cannot be adjusted with the height of the mower. The power transmission from the engine to the cutter of the existing commercial follow-up lawn mower is realized through the V-shaped transmission belt. After adjusting the height of the header from the ground, due to the height difference between the engine pulley and the two cutter pulleys, The V-shaped transmission belt cannot be driven in the same horizontal plane, and c...
