The transfer plate 31 is of a rectangular frame structure, a pair of rotating plates 32 are hinged to two opposite side edges of the transfer plate 31, and hinge shafts of the rotating plates 32 are perpendicular to the sliding direction of the transfer plate 31. By rotating the pivotal plates 32 about the hinge shafts, opening and closing between the pair of pivotal plates 32 can be achieved. When the rotating plates 32 are opened downward as shown in fig. 11 and 13, the bagged bio-fertilizer 2 falls on the tray 1 through the blanking hole 201 from between the pair of rotating plates 32 downward. When the rotating plates 32 are folded as shown in fig. 1 and 2, the rotating plates 32 are both parallel to the platform 20, and the bagged biological fertilizer 2 can slide on the rotating plates 32 to realize loading of the bagged biological fertilizer 2.

When the connection plate 231 drives the push plate 24 to move from the output part 30 to the conveyor belt 21, if the bagged biological fertilizer 2 is temporarily stored on the transfer track 22, the push plate 24 will rotate around the hinge axis between the connection plate 231 under the blocking effect of the bagged biological fertilizer 2 to avoid the bagged biological fertilizer 2. To prevent the bagged bio-fertilizer 2 from being continuously pushed toward the output part 30 when the output part 30 is misaligned with the transfer rail 22, an automatic stopper may be provided at an exit position of the transfer rail 22 to prevent the bagged bio-fertilizer 2 from being pushed by the conveyor belt 21.

As shown in fig. 6 and 8, the rotating plates 32 are provided with side plates 321, when the rotating plates 32 are folded, the side plates 321 are perpendicular to the transferring plate 31, and the bagged biological fertilizer 2 slides on the rotating plates 32 and is located between the side plates 321 of the two rotating plates 32.

Preferably, as shown in fig. 4, 6 and 8, the rotating plate 32 is provided with a plurality of pulleys 322 in an array, and an included angle between the axis of the pulley 322 and the sliding direction of the bagged biological fertilizer 2 on the rotating plate 32 is 45 °; the pulley is arranged to enable the bagged biological fertilizer 2 to slide into the output part 30 more smoothly; the central axis of the pulley 322 is designed to form an angle of 45 degrees with the conveying direction of the bagged biological fertilizer 2, so that the effect that the bagged biological fertilizer 2 smoothly enters the output part 30 is considered, and the bagged biological fertilizer 2 can smoothly and downwards fall into the tray 1.

Preferably, as shown in fig. 1 and 2, the top surface of the platform 20 is provided with a pair of parallel sliding grooves 202, the sliding grooves 202 are perpendicular to the conveying direction of the conveying belt 21, the bottom of the transfer plate 31 is provided with rollers 33, and the rollers 33 are rolled in the sliding grooves 202, so that the output member 30 can be prevented from moving along the conveying belt 21, and the position stability of the output member 30 can be ensured when the output member 30 is loaded with the bagged biological fertilizer 2.

More specifically, a rack 25 is provided on the top surface of the platform 20, the rack 25 is parallel to the sliding direction of the transfer plate 31, the output members 30 are each provided with a driving motor 34, a main shaft of the driving motor 34 is provided with a gear 341, and the gear 341 is engaged with the rack 25.

Preferably, as shown in fig. 4, 6 and 8, the transfer plates 31 are provided with an adjusting mechanism 40 for controlling the opening and closing of the rotating plates 32. The adjusting mechanism 40 includes a connecting rod 41, which is erected above the transfer plate 31, and the length of the connecting rod 41 is smaller than or equal to the width of the transfer plate 31 to control the overall width of the output components 30, and when two sets of output components 30 are simultaneously arranged on the platform 20, the width of the output components 30 will affect the position layout of the two sets of output components 30 when working simultaneously; the connecting rod 41 is perpendicular to the axis of rotation of the transfer plate 31; the connecting rod 41 is provided with a pair of sliding blocks 42 in a sliding manner, and the sliding direction of the sliding blocks 42 is perpendicular to the rotating axis of the transfer plate 31; the sliding blocks 42 are all provided with sliding rods 43 in a sliding and penetrating mode, and the sliding rods 43 are perpendicular to the transfer plate 31; the bottom of the sliding rod 43 is hinged to one of the rotating plates 32, and the sliding rod 43 is hinged to a side plate 321 of the rotating plate 32.

When the rotating plate 32 is opened as shown in fig. 11 and 12, the slider 42 simultaneously moves toward the middle of the connecting rod 41, and the sliding rod 43 shifts the rotating plate 32, so that the rotating plate 32 rotates around the hinge shaft with the transfer plate 31; the sliding rod 43 moves the rotating plate 32 and simultaneously the sliding rod 43 and the rotating plate 32 rotate relatively, and since the position of the hinge joint of the sliding rod 43 and the rotating plate 32 changes along with the rotation of the rotating plate 32, the sliding rod 43 slides in the sliding block 42 in the process, and the position of the hinge joint of the sliding rod 43 and the rotating plate 32 changes, so that the position is not coaxial with the position of the hinge joint between the rotating plate 32 and the transferring plate 31. The principle of closing the rotating plate 32 is the same as that of opening the rotating plate 32, and the sliding rod 43 is moved by the sliding block 42 to rotate the rotating plate 32, and the sliding rod 43 is driven to slide in the sliding block 42 due to the rotation of the rotating plate 32. Compared with the traditional mode of driving the rotating plate 32 to rotate by using a cylinder type telescopic device or a motor type rotating device, the adjusting mechanism 40 of the application can ensure that the output part 30 has smaller width dimension.

Further preferably, the adjusting mechanism 40 is provided with a bidirectional screw 44, the bidirectional screw 44 is parallel to the sliding direction of the sliding blocks 42, two opposite threads are arranged at two ends of the bidirectional screw 44, the two threads are respectively in threaded connection with one of the sliding blocks 42, and the two sliding blocks 42 can simultaneously move in opposite or opposite directions by rotating the bidirectional screw 44, so that the rotating plates 32 can be opened or closed simultaneously.

Further preferably, as shown in fig. 4, 5, 7 and 9, the connecting rod 41 is connected with a sliding block 42 through a T-shaped groove structure, one end of the sliding block 42 is used for sliding through a sliding rod 43, and the other end of the sliding block is used for connecting with a bidirectional screw 44. The sliding rod 43 and the bidirectional screw 44 are respectively positioned at two sides of the connecting rod 41, so that the structural distribution is more balanced, the arrangement is more reasonable, and the unilateral structure is convenient to simplify.

Further preferably, as shown in fig. 10, a worm wheel 45 is coaxially arranged at the middle position of the bidirectional screw 44, the worm wheel 45 is meshed with a worm 46, the worm 46 is driven by a motor, the motor is arranged on the connecting rod 41, the worm wheel 45 and the worm 46 are matched for transmission, and the worm wheel 45 is arranged at the middle position of the bidirectional screw 44, so that the structural size of the output component 30 in the width direction is reduced, and the motor is prevented from being arranged at positions beyond two ends of the connecting rod 41; meanwhile, the two ends of the bidirectional screw 44 are stressed more uniformly; moreover, because the output part 30 is fully stressed by the rotating plate 32 when bearing the bagged biological fertilizer 2, in order to prevent the rotating plate 32 from rotating under the action of the gravity of the bagged biological fertilizer 2, the sliding block 42 can never slide by itself, but to prevent the sliding block 42 from sliding by itself, the bidirectional screw 44 needs to be ensured not to rotate, and the bidirectional screw 44 can be effectively prevented from rotating by utilizing the transmission structure of the worm wheel 45 and the worm 46, so that the purpose of fixing the rotating plate 32 is achieved.

Further preferably, the hinge joint of the sliding rod 43 and the rotating plate 32 is located at the middle position of the rotating plate 32, so that the stress at the two ends of the rotating plate 32 is more uniform, the rotating plate 32 is prevented from deforming, and the structural size of the output component 30 in the length direction can be reduced; as for the control manner of rotating the rotating plate 32, some rotating motors are directly and indirectly connected to one end of the rotating shaft of the rotating plate 32, and the rotating plate 32 is driven to rotate by the rotating motors, but this structure increases the length of the structure, and only one end of the rotating plate 32 provides a rotating moment, which causes the other end of the rotating plate 32 to bear a large weight, thereby causing the rotating plate 32 to deform.

The specific implementation mode is as follows: the bagged biological fertilizer 2 is input into the transfer track 22 through the conveyor belt 21, when one group of the output parts 30 is aligned with the transfer track 22, the linear moving mechanism 23 drives the push plate 24 to push the bagged biological fertilizer 2 into a predetermined position on the rotating plate 32 of the output part 30, and the bagged biological fertilizer 2 in the front position of the output part 30 is pushed by the bagged biological fertilizer 2 in the rear part and continues to move towards the front end of the output part 30 because the push plate 24 cannot pass through the adjusting mechanism 40. In this embodiment, each set of output members 30 can simultaneously hold 3 bags of bagged bio-fertilizer 2. After the output part 30 is filled with 3 bags of the bio-fertilizer 2, the gear 341 is moved to a predetermined position along the rack 25 by the driving motor 34. At this time, the lifting table 10 has lifted the tray 1 to a predetermined height position by the lifting device 12. Then the rotating plates 32 are opened through the adjusting mechanism 40, so that the distance between the rotating plates 32 is increased, the bagged biological fertilizer 2 can fall down from the rotating plates 32 and then smoothly fall on the tray 1 upwards. After the tray 1 is stacked with a layer of bagged biological fertilizer 2, the rotating mechanism 13 drives the lifting platform 10 and the tray 1 to rotate together for 90 degrees, and the stacking of the upper layer is carried out. After the predetermined number of stacking layers is completed, as shown in fig. 14, the lifting platform 10 is lowered into the foundation pit 11, and the tray 1 is supported in the limit pit 14.

The foregoing is only a preferred embodiment of the present invention and is not intended to be exhaustive or to limit the invention. It will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the scope of the invention.
