A hammer wheel mechanism capable of adjusting the grinding force of an annular type upright mill is provided, wherein a swinging arm is provided on a stelliform support via a swinging arm shaft, a hammer wheel is provided on a first end of the swing arm via a hammer wheel shaft, and a counterweight is provided on the swinging arm via an adjuster bolt. The present invention has beneficial effects as follows. The counterweight capable of moving transversely along the swinging arm is provided on a second end of the swinging arm of the hammer wheel. When the machinery is operating, the counterweight generates an inert centrifugal force simultaneously. According to the principle of the plane force system, a balancing torque is generated on a fulcrum. Adjusting corresponding position of the counterweight or changing the weight of the counterweight itself is capable of setting or adjusting the grinding force of the hammer wheel, so as to achieve an optimal effect, in such a manner that the machinery is capable of effectively grinding materials, the quality of the product is improves and production efficiency of the machinery is improved.
