Description

Mowing implements that can prevent entanglement and jam

The present invention relates to the improvement of the structure of the accessories of the mowing device. Specifically, when the mowing operation is performed, foreign objects can be prevented from being entangled in the gap between the mowing device and the transmission member, so as to avoid causing the mowing device due to its Mowing implements that are stuck in the winding and stop functioning.

Generally, in the structural design of a lawn mower with a lawn mower, a disk body is generally used to assemble a lawn mower for the periphery of the disk body to extend outward. The lawn mower is connected to the transmission part of a lawn mower, and after the motor or the engine rotates, it rotates horizontally according to its power source to perform the purpose of mowing operations. Generally, the most common mowing tools are made of plastic nylon as the main accessories for mowing. Generally, the most common lawn mowers are designed mainly for safe operation and labor-saving.

However, when the user actually operates the mowing device, the mowing cutter cuts the grass to a fixed height along with the horizontal rotation of the disc body. After the mowed grass loses its grip, it will fly in the air following the direction of the force line of the mowing cutter. During the fluttering period, the grass may be entangled in the gap between the lawn mower and the transmission member. When the gap accumulates too many foreign objects, the mowing device will be jammed and unable to effectively transmit the motor or The power source of the engine causes the mowing implement to stop rotating. At this time, the mowing device must be stopped first, and the entanglement of foreign objects in the gap must be removed before the mowing device can be restarted to perform the mowing operation. With the increase of the mowing area and/or the mowing frequency, its relative increase The entanglement jam occurs.

Therefore, in view of this, the inventor has studied and improved the existing shortcomings, and provided a lawn mower that can prevent entanglement and jamming.
