Description

[Detailed Description of the Invention] (Industrial Application Field) This invention is an egg discharging device for collecting eggs, such as chicken eggs, carried by an egg collection belt from single or multi-stage cages into one place. Regarding.

(Prior Art) When transferring eggs, it is not so difficult to transfer them only in the horizontal direction, but it is difficult to transfer eggs located on a horizontal transfer path to an inclined or vertical transfer path, which is different from the transfer path. When transferring the eggs to egg collecting tables or the like located at different heights, it is difficult to perform each transfer operation smoothly, often resulting in broken eggs. The need for inclined or vertical transfer to different height positions on the transfer path arises when eggs are collected using multi-tiered cages for the purpose of egg collection.

For example, an example of poultry farming using a multi-stage cage type poultry house will be described. Eggs laid by the chickens raised in each cage roll out of each cage and are transferred to one end of the chicken house on an egg collection conveyor that performs horizontal transfer installed along each cage. . Then, at this one end, the eggs are transferred to an egg collection table or the like by a transfer device.

The conventional transfer device described above is shown in FIG.

1 is an egg collecting conveyor provided along the cage. 2 is a transfer device, and 2 is placed above and below.
A belt 4 is stretched around the two pulleys 3a and 3b, and protruding mounting members 4a are protruded from the belt 4 at predetermined intervals. 5 is an egg collecting stand.

Then, the tip of the egg collection conveyor 1 and the egg collection table 5
A comb-shaped mounting rod 6 is provided at the front end.

Therefore, the eggs sent by the egg collecting conveyors 1, 1, .

The sent eggs are then reversed along the belt 4 from the cage side to the egg collecting table 5 side (from upward to downward), received by the mounting rod 6 of the egg collecting table 5, and discharged.

(Problems to be Solved by the Invention) However, when the eggs are discharged by the transfer device 2, foreign matter may be present when the eggs are transferred from the loading member 4a to the loading rod 6 for discharge of the egg collecting table 5. There is a risk that the mounting member 4a and the mounting rod 6 may be deformed or damaged.

Therefore, this idea was made in view of the above circumstances,
An object of the present invention is to provide an egg discharging device having a stopper mechanism to prevent damage to an endless egg collection conveyor.

(Means for Solving the Problems) The egg ejecting device according to this invention has the following configuration.

An egg placed on a comb blade-shaped receiving part is received by a discharging part in which a discharging piece that engages with the receiving part is arranged at an angle in the discharging direction, and the eggs are discharged in the direction of the inclination of the discharging part. In this ejecting device, one end of the ejecting portion is rotatably supported, and the ejecting portion is held in an inclined state by elastic force, so that the ejecting portion becomes resilient due to foreign matter interposed between the receiving portion and the ejecting portion. In order to stop the movement of the receiving part when it rotates against the force,
It is characterized in that the discharge part and a stopper mechanism that senses the rotation of the discharge part are linked.
