Thus, when the slow synchronization driving assembly 113 moves along the direction 114, the slow moving frame assembly 112 moves along the direction 115, and vice versa. Wherein 114 is the same as the second direction 165, 158 and 115 is the same as the first direction 164, 157.

Referring to fig. 2 and 23-28, a driving mechanism 151 is connected with a fast moving frame assembly 116 and a slow synchronous driving assembly 113 in a synchronous transferring device 152 through a fast driving connecting rod 154 and a slow driving connecting rod 155 respectively. The synchronous sliding block 33 in the egg receiving device 153 is mounted on the sliding round bar 76 in the synchronous transfer device 152, so that the whole egg receiving device 153 can slide along the sliding round bar 76, the sliding direction is controlled by the slow moving frame assembly 112 in the synchronous transfer device 152 through the egg receiving driving connecting bar 156, the other end 156B of the egg receiving driving connecting bar penetrates through the sliding cylindrical sleeve 78 to be sleeved on the connecting bar 32 of the egg receiving device 153, and one end 156A of the egg receiving driving connecting bar is embedded in the slow frame sliding chute 92 in the slow moving frame assembly 112. When the egg receiving device 153 reciprocates left and right along the direction 158, the inclined surface structure on the egg receiving opening and closing rail 98 in the synchronous transfer device 152 controls the movement states of the inner adjusting opening and closing rod 31 and the outer adjusting opening and closing rod 34 of the egg receiving device 153, so that the egg receiving device is opened 153 at a designated position to release eggs from the egg-carrying space.

When the cam shaft 131 rotates, the egg receiving device 153 can reciprocate along the direction 157 and the direction 158 on a plane, and the speed of eggs is synchronous with the speed of a conveying line in the egg receiving and placing process.

In the egg receiving process, referring to fig. 23 and 24, the cam shaft 131 rotates to drive the slow synchronous cams 135 and 133 to rotate, the fast synchronous cam 133 is in a resting state during egg receiving, the slow synchronous cam 135 is in a pushing stroke working state, at this time, the slow synchronous passive swing arm 128 rotates in the direction 171, the slow synchronous driving assembly 113 moves in the direction 172, the chute driving block 101 also moves in the direction 172, the slow moving frame assembly 112 moves in the direction 173 under the driving of the chute plastic block by the driving of the chute driving assembly 101, and the plastic chute 92 in the slow moving frame assembly 112 pulls the egg receiving device 153 to move together in the direction 173. As can be seen from the above figures, the egg receiving opening and closing rail 98 does not apply force to the inner adjusting opening and closing lever 31, and the egg receiving device 153 is in a free closed state.

In the egg laying process, when the mechanism state is shown in fig. 25 after the egg receiving is finished, the slow synchronous cam 135 enters a resting state, the fast synchronous cam 133 enters a pushing working state, the fast passive swing arm 1214 rotates along 183 direction under the drive of the fast synchronous cam 133, and the whole fast moving frame assembly 116 is driven to move along 181 direction, so that the egg receiving device 153 moves along 181 direction together with the fast moving frame assembly 116.

The egg receiving device 153 starts to accelerate from rest, when the speed is consistent with the rapid transport line 163 (as shown in fig. 26 and 27), the egg receiving opening and closing rail 98 pushes the inner adjusting opening and closing rod 31 to the illustrated position along 193 direction by using the inclined surface structure, so that the egg receiving opening and closing rail 98 is in an opened state (as shown in a third state diagram in fig. 9), the egg is released by the egg receiving opening and closing rail 98, and the egg receiving opening and closing rail 98 coincides with the rapid transport line 163 at this time, and the egg can synchronously enter the rapid transport line 163.

The egg receiving device 153 always keeps speed synchronization with the quick conveyor line 163 during the process of feeding eggs into the quick conveyor line 163, and keeps for a period of time, and after eggs completely enter the quick conveyor line 163, the egg receiving device 153 starts to decelerate until being stationary under cam control.

The return process is that when the egg receiving device 153 finishes laying eggs and decelerates to rest, the state is as shown in fig. 28, and then the egg receiving device 153 starts to return. The slow synchronous passive swing arm 128 starts to rotate along the direction 202, the fast passive swing arm 1214 starts to rotate along the direction 201, at this time, the egg receiving device 153 has a minute speed along the direction 205 and a minute speed along the direction 204, and in the return process, the egg receiving device accelerates first, decelerates to be stationary, and returns to the initial state of fig. 23.
