Description

The present invention relates to an oscillating sorting stone removing device including an inclination sorting plate that is oscillated and driven by an eccentric support shaft.

As in the example described in Patent Document 1, there is known an oscillating sorting type stone removing device that is provided with a tilt sorting plate that is oscillated and driven by an eccentric support shaft at the front end. This stone removing device is provided with respective support links before and after the inclined sorting plate and is driven by an eccentric support shaft so as to perform a swinging operation with a constant amplitude, and a balance weight is provided on the front support link to provide a swing sorting member. The swinging power can be kept small by balancing with the moment due to the weight.

However, while the above stone removing device can reduce power loss, it may cause vibration and noise of the entire device at the time of swing selection, and in particular, a stone with a small configuration designed to reduce the weight of the support frame. In the punching device, the swing reaction force of relatively large amplitude action is transmitted to the lightweight support frame,
As a result, the vibration of the entire apparatus is unavoidable, and it has a problem in terms of operation noise and durability.

The invention according to claim 2 is characterized in that, in the invention according to claim 1, the both balance weights are arranged in the vicinity of the center of the width of the sorting plate which is the position of the center of gravity in the width direction of the swing sorting member.

The invention according to claim 3 is the invention according to any one of claims 1 to 2 , wherein the drive eccentric support shaft is provided with a balance weight that balances the eccentric moment.

According to the first aspect of the present invention, by individually balancing the swing selection members in the inclined posture with the balance weights of the respective support links, the swing due to the gravity of the swing selection members is minimized. In addition to being able to be driven dynamically, the moment around the center of gravity due to the swinging motion can be kept small. Therefore, even in a small-sized stone removing device that reduces the weight of the support frame, the driving power is reduced and the vibration of the entire device is suppressed to enable stable operation.

In addition, since the balance weight is attached to the extension end position of the extension arm in which the respective support links are extended in the front-rear direction from the support point, the length of the extension arm and the weight mass should be suppressed to be compact. Can do.

According to the invention according to claim 2 , in addition to the effect of the invention according to claim 1, the both balance weights are arranged in the center in the width direction of the sorting plate portion of the swing sorting member. Since a stable posture is ensured by the balance in the width direction, vibration in the width direction of the entire apparatus is suppressed, and a stable operation is possible.

According to the invention according to claim 3 , in addition to the effect of the invention according to any one of claims 1 to 2 , the driving eccentric support shaft is provided with a balance weight that balances the eccentric moment. The balance weight of the eccentric support shaft can reduce the vibration and noise of the entire device generated from the drive unit.

Embodiments specifically configured based on the above technical idea will be described below with reference to the drawings.
FIG. 1 and FIG. 2 are a side view and a rear view in which the internal equipment of the stone removing device 1 is displayed in a transparent manner.
The stone extraction device 1 supports a front and back by tilting a rocking selection member 3 integrally formed with a wind tunnel 3a and a porous selection surface thereof to a selection angle of a lower front, on a support frame 2 made of a box-shaped exterior material. Substantially parallel support links 4a, 4b, an eccentric support shaft 5 that is connected to the swing selection member 3 and swings by an eccentric rotation operation, an electric motor 6 that is powered by belt transmission, and a grain that faces the swing selection member 3 It is comprised by the grain hopper 7 grade | etc.,.

The oscillating sorting member 3 includes a sorting plate 11 having a mesh structure inclined upward, and the lower side thereof has a wind tunnel 3.
A return chute 11a is attached to one side of the sorting plate 11 while being configured as a.
The wind tunnel 3a is internally provided with air blowing blades 12 penetrating the left and right sides and pivotally supported by the support frame 2.
Further, the wind tunnel 3a and the rear eccentric support shaft 5 are connected by a link 5a, and the link 5a
The balance weights 5b, 5b for balancing are attached to the eccentric support shaft 5. In order to drive the eccentric support shaft 5 and the blower blades 12, the motor 6 is connected by a transmission belt 13 having a tensioner 13 a arranged outside the support frame 2.

Further, as shown in the side view of FIG. 3, the support links 4a and 4b on the front and rear of the swing sorting member 3 are provided with support shafts 21a and 21b at the front and rear positions of the wind tunnel 3a so as to support both ends from below. The support frames 2 are pivotally supported at fulcrums 22a and 22b, and the extension arms 23a and 23b are rearwardly extended from the fulcrums 22a and 22b.
