[0048] The specific embodiments of the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the embodiments of the present application, and are not intended to limit the embodiments of the present application.

[0049] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0050] In the embodiments of the present application, the orientation words such as "upper", "lower", "top", "bottom" are generally used for the directions shown in the drawings or the positional relationship between the components in the vertical, perpendicular or gravity direction, unless otherwise stated.

[0051] The present application will be described in detail below with reference to the accompanying drawings and in combination with exemplary embodiments.

[0052] A first aspect of the present application provides an automatic feeding device, which comprises a driving mechanism and a plurality of feeding mechanisms, each feeding mechanism comprising a feeding hopper 11 and a quantitative orifice plate 12, the bottom of the feeding hopper 11 being provided with a hopper outlet, the quantitative orifice plate 12 being provided with a quantitative orifice 121, and the quantitative orifice plate 12 being arranged below the feeding hopper 11. The driving mechanism comprises a driving frame body 22 and a driving member 21, the plurality of quantitative orifice plates 12 being uniformly and spacedly arranged on the driving frame body 22, and the driving member 21 being drivingly connected with the driving frame body 22 and being used to drive the driving frame body 22 to reciprocate, so that the quantitative orifice plate 12 can be switched between an open position and a closed position. In the open position, the quantitative orifice 121 is arranged in alignment with the hopper outlet so that the quantitative orifice plate 12 opens the hopper outlet; in the closed position, the quantitative orifice 121 is arranged out of alignment with the hopper outlet so that the quantitative orifice plate 12 closes the hopper outlet.

[0053] The second aspect of the present application also provides an automatic production line, which comprises a conveyor 3, a feeding rack 4 and the automatic feeding device described above, the conveyor 3 is used to longitudinally convey the holding container 5, the feeding rack 4 is erected above the conveyor 3, and the automatic feeding device is arranged on the feeding rack 4 and can feed towards the holding container 5.

[0054] It can be seen that the automatic feeding device and the automatic production line of the present application are provided with multiple feeding mechanisms, which comprise the fixedly arranged feeding hopper 11 and the movably arranged quantitative orifice plate 12, the automatic feeding device is arranged above the conveyor 3 through the feeding rack 4, and the holding container 5 is placed on the conveyor 3. When the holding container 5 passes below the automatic feeding device, the system detects the holding container 5, the automatic feeding device automatically feeds, and the quantitative orifice plate 12 is driven to open or close the hopper outlet of the feeding hopper 11 through the reciprocating movement of the driving member 21, so that the automatic feeding of a large batch of seeds at a fixed time and a fixed quantity can be realized. After the automatic feeding of the seeds is completed, the holding container 5 flows away, and the automatic feeding device feeds the next basket of seeds. In this way, the production efficiency can be effectively improved. In addition, the multiple quantitative orifice plates 12 are all mounted on the driving frame body 22, the driving member 21 drives the driving frame body 22 to simultaneously drive the multiple quantitative orifice plates 12 to feed, so that the overall structure is reasonable and compact, and the production cost is low.

[0055] Alternatively, the automatic production line of the present application is used for silkworm breeding, the automatic feeding device is used for feeding silkworm eggs, and the holding container 5 is a silkworm frame. Since the feeding silkworm eggs must be quantitative, unbroken, accurately positioned, and as low as possible in height, the damage to the silkworm eggs is reduced. The existing manual feeding of silkworm eggs has low feeding efficiency, high labor cost, and uneven accuracy of feeding quantity and feeding position, and it is difficult to accurately control the feeding height and feeding strength, so the loss of silkworm eggs is large, and the qualified rate needs to be improved. The use of the automatic feeding device of the present application for feeding silkworm eggs can effectively ensure the accuracy of the feeding position of the silkworm eggs, and the feeding height is appropriate, which effectively avoids the damage to the silkworm eggs, reduces the loss rate, and adapts to the rhythm of modern flow production line for silkworm breeding.

[0056] Specifically, as shown in Figure 1 and Figure 2 , the conveyor 3 is a conveyor belt structure, the feeding rack 4 is erected above the conveyor 3, the upper part of the feeding mechanism 4 comprises a rectangular frame body, the automatic feeding device is arranged on the rectangular frame body, the fixed end of the driving member 21 and the feeding hopper 11 are fixedly installed, and the driving frame body 22 is movably arranged on the rectangular frame body. The holding container 5 is a silkworm frame, the silkworm frame carries a silkworm breeding plate, the silkworm breeding plate carries silkworm breeding feed materials and is conveyed to the lower part of the automatic feeding device by the conveyor 3.

[0057] The automatic feeding device can also be equipped with a positioning detection system to detect the arrival of the silkworm frames. After the positioning detection system detects that the silkworm frames are in place, the drive unit 21 drives the drive frame 22 to move, thereby moving the quantitative orifice plate 12 to the closed position. At this time, the quantitative orifice 121 is staggered with the hopper outlet so that the quantitative orifice plate 12 closes the hopper outlet, thus filling the feeding hopper. After the feeding hopper 11 is filled, the drive unit 21 drives the drive frame 22 to move in the opposite direction, thereby moving the quantitative orifice plate 12 to the open position. At this time, the quantitative orifice 121 is aligned with the hopper outlet so that the quantitative orifice plate 12 opens the hopper outlet, and the silkworm eggs fall automatically. After the feeding is completed normally, the conveyor 3 starts and sends away the silkworm frames that have been fed. The automated silkworm rearing production line can repeat the above actions to achieve continuous feeding.

[0058] In addition, such as Figure 1 and Figure 2 As shown, the automatic feeding device is equipped with eight feeding hoppers 11 and eight metering plates 12, arranged in two rows and four columns, corresponding to the layout of the silkworm basket feeding trough. This arrangement adapts to the area of ​​the silkworm basket feeding trough, making the quantity and spacing of silkworm eggs more reasonable. Furthermore, the distance between each metering plate 12 and the silkworm basket feeding trough can be adjusted to a suitable and uniform feeding height, greatly reducing damage to the silkworm eggs.

[0059] It should be noted that the number of feeding hoppers 11 and metering orifice plates 12 can be adjusted according to the area of ​​the silkworm feeding trough plate, and can be 6, 10, 12, 16, etc. The arrangement of multiple feeding hoppers 11 and metering orifice plates 12 can also be 3 rows and 4 columns, 2 rows and 5 columns, etc., and the invention is not limited to these. The number of feeding hoppers 11 and metering orifice plates 12 can be set in a one-to-one correspondence; alternatively, multiple feeding hoppers 11 can correspond to one metering orifice plate 12, with multiple metering orifice plates 12 having multiple metering orifices corresponding one-to-one with the hopper outlets of the feeding hoppers 11, etc., and the invention is not limited to these. The structure of the drive frame 22 can also be varied, and can be provided with multiple horizontal and vertical connecting plates or horizontal and vertical connecting rods, etc. The drive component 21 can be a drive cylinder or a drive motor, etc. The drive component 21 can be directly connected to the drive frame 22, or it can be connected to the drive frame through an intermediate drive structure, and the invention is not limited to these.

[0060] In some embodiments, the feeding mechanism further comprises a detection device 13 arranged above the quantitative orifice plate 12 and capable of being arranged in alignment with the quantitative orifice 121 in the closed position of the quantitative orifice plate 12 to detect the feeding condition. In this way, after the feeding is completed, the driving member 21 drives the driving frame body 22 to move to drive the quantitative orifice plate 12 to move to the closed position, at which time the detection device 13 is arranged in alignment with the quantitative orifice 121 to detect the feeding position. The detection device 13 detects the feeding condition to determine whether the feeding position is short of material, thereby ensuring the accuracy of feeding. In addition, the subsequent process can also determine whether the seeds need to be supplemented or the seasoning needs to be supplemented according to the feeding condition, or whether the automatic feeding device needs to be repaired, etc. As shown in Figure 1 、 Figure 2 、 Figures 4 to 6 each quantitative orifice 121 can be provided with one detection device 13, so that the overall information of this feeding can be determined by automatically counting the detection condition of the system.

[0061] Further, the detection device 13 can comprise a limiting installation block 131 and a detection sensor 132, the limiting installation block 131 is provided with a sensor installation hole, and the detection sensor 132 is inserted into the sensor installation hole through a height-adjusting bolt 133. The detection device 13 can be fixedly installed on the feeding rack 4 through the limiting installation block 131, and the detection sensor 132 is inserted into the sensor installation hole of the limiting installation block 131 through the height-adjusting bolt 133, so that the height of the detection sensor 132 can be adjusted according to the actual use requirement, so that the structure of the detection device 13 is more reasonable and reliable, and the adaptability is good.

[0062] Specifically, as shown in Figure 6 、 Figure 8 and Figure 9 , the sensor installation hole is located in the middle of the limiting installation block 131, and the limiting installation block 131 is further provided with a positioning installation hole located on both sides of the sensor installation hole, and the limiting installation block 131 is fixedly installed on the feeding rack 4 through a fastener.

[0063] In the process of discharging, the material body or more or less will have some falling and adhering to the quantitative hole 121, resulting in the blockage of the quantitative hole 121, affecting the normal operation of the feeding. Therefore, further, the limiting mounting block 131 bottom can be provided with a groove part 134, the groove part 134 is located below the sensor mounting hole and communicates with the sensor mounting hole, and the bottom of the height adjusting bolt 133 is provided with a cleaning brush ring 135 for cleaning the quantitative hole 121. In this way, the cleaning brush ring 135 extends downward from the bottom of the height adjusting bolt 133, the upper part is accommodated in the groove part 134, and the lower part extends out of the groove part 134, so as to clean the quantitative hole 121. And the cleaning brush ring 135 is arranged around the detection sensor 132, which can clean the hole edge part of the quantitative hole 121 in all directions, and can also avoid interfering with the detection sensor 131, and the overall structure is reasonable and reliable, and simple and compact.

The driving frame body 22 is connected by the plurality of transverse connecting plates 221 and longitudinal connecting plates 222, and the structure is reasonable and simple, and the production cost is low. A plurality of quantitative hole plates 12 are arranged at equal intervals along the transverse direction on each transverse connecting plate 221, and the plurality of quantitative hole plates 12 all extend along the longitudinal direction, so that only one driving member 21 can be arranged to drive the driving frame body 22, and then a plurality of quantitative hole plates 12 can be uniformly driven, and the driving structure and driving control are simple, and large quantities of seeds can be simultaneously and uniformly planted.

[0065] Specifically, as shown in Figure 4 and Figure 5 The driving frame body 22 is movably arranged above the conveyor 3 through the feeding frame 4, the plurality of transverse connecting plates 221 of the driving frame body 22 are perpendicular to the conveying direction of the conveyor 3, and the longitudinal connecting plates 222 of the driving frame body 22 are parallel to the conveying direction of the conveyor 3. The transverse connecting plates 221 are arranged at two intervals along the longitudinal direction, and the longitudinal connecting plates 222 are arranged at one along the longitudinal direction and connected at the middle of the two transverse connecting plates 221, and the driving member 21 is drivingly connected with one end of the longitudinal connecting plates 222 to drive the driving frame body 22 to reciprocate along the longitudinal direction. Four quantitative hole plates 12 are arranged at equal intervals along the transverse direction on each transverse connecting plate 221, and each quantitative hole plate 12 extends along the longitudinal direction, so that each quantitative hole plate 12 also reciprocates along the longitudinal direction at the same time when the driving frame body 22 reciprocates along the longitudinal direction.

[0066] In addition, the feeding hopper 11 can be provided with a plurality of hopper 111 in the longitudinal direction, each hopper 111 is provided with a hopper outlet, the quantitative orifice plate 12 is provided with a plurality of quantitative orifice 121 in the longitudinal direction, and the plurality of quantitative orifice 121 can be one-to-one aligned with the plurality of hopper outlets.

[0069] Further, the driving frame body 22 can further include a linear guide pair 223, which extends in the longitudinal direction and is respectively connected with the plurality of transverse connecting plates 221 in sliding connection. In this way, the driving member 21 drives the quantitative orifice plate 12 to move back and forth to realize the cyclic action of quantitative seeding and seeding, and the quantitative orifice plate 12 moves linearly under the constraint of the linear guide pair 223, so that the overall structure is more reasonable and reliable.
