[0020] A plurality of fixed pieces 782 are uniformly fixed at the middle portion of the I-shaped roller 78, through the arrangement of the above structure, the I-shaped roller 78 drives the fixed pieces 782 to actively move the fertilizer bag hooked by the inclined prongs 76 to the inclined prongs 76 during the rotation process, thereby helping to enhance the contact force between the fertilizer bag and the inclined prongs 76, ensuring that the fertilizer bag can be firmly hooked, and avoiding the phenomenon of fertilizer bag slipping or falling off during the movement.

[0021] The bag removing device 7 further comprises an elliptical slot plate 710, two elastic telescopic rods 711, and two trapezoidal plates 714. The elliptical slot plate 710 is fixed at the outer wall of the rotating shaft of the driving roller 72, and an elliptical slot is formed in the outer wall of the elliptical slot plate 710. The two elastic telescopic rods 711 are respectively slidably installed on the two sides of the through slot plate 79. The elastic telescopic rods 711 are fixed with a connecting plate 712 between the extension ends away from one side of the fertilizer tank 2. A sliding column 715 is fixed on the outer wall of one side of the elastic telescopic rod 711 and slidably installed in the elliptical slot of the elliptical slot plate 710. A plurality of sharp spikes 713 are evenly and equidistantly fixed on the side of the connecting plate 712 close to the through slot plate 79, and the plurality of sharp spikes 713 respectively pass through the plurality of through slots of the through slot plate 79. The two trapezoidal plates 714 are respectively fixed on the two sides of the side of the through slot plate 79 away from the fertilizer tank 2. The top of the trapezoidal plate 714 is provided as an inclined surface. The inclined surface of the trapezoidal plate 714 is located on the movement track of the connecting plate 712. There is a five-centimeter gap between the trapezoidal plate 714 and the connecting plate 712. When the fertilizer bag is moved to the position of the through slot plate 79 by the oblique spike plate 76 each time, the above structure is arranged so that the sharp spikes 713 pull the fertilizer bag to move downward, thereby facilitating the separation of the fertilizer bag from the oblique spike plate 76. At the same time, the above structure is arranged so that the connecting plate 712 moves downward with the sharp spikes 713 for a distance and is separated from the fertilizer bag, thereby ensuring that the fertilizer bag can effectively fall at the discharge port of the circular shell 71.

[0022] In use, the cover plate 54 is opened, and the bagged fertilizer is thrown onto the conveying belt group 53. The conveying belt group 53 is started, and the conveying belt group 53 first transports the bagged fertilizer to the cutting knife group 52. The cutting knife group 52 cuts the fertilizer bag. Then, the conveying belt group 53 transports the fertilizer to the inside of the filter screen cylinder 61. The driving motor 64 drives the belt pulley 63 to rotate. The belt pulley 63 drives the belt ring 62 to rotate through the belt. The belt ring 62 drives the filter screen cylinder 61 to rotate, so that the filter screen cylinder 61 rotates to pour the fertilizer into the fertilizer tank 2. Then, the screw feeding assembly 3 is started. The screw feeding assembly 3 pours the fertilizer into the production equipment, thereby realizing the feeding operation of the fertilizer. The rotating design of the filter screen cylinder 61 can buffer the speed in the process of pouring the fertilizer, which can effectively avoid the blockage of the fertilizer in the pouring process, ensure that the fertilizer can smoothly enter the screw feeding assembly 3, and improve the continuity and reliability of the feeding. At the same time, the rotation of the filter screen cylinder 61 can prevent the fertilizer from caking due to static in the fertilizer tank 2, maintain the fluidity of the fertilizer, and the inclined surface of the driving plate 65 is arranged, so that the driving plate 65 can continuously drive the fertilizer bag during the rotation process, so that the fertilizer in the fertilizer bag can be completely poured out of the fertilizer bag. The inclined surface of the driving plate 65 is arranged, so that the driving plate 65 can continuously drive the fertilizer bag to the direction away from the feeding port of the fertilizer tank 2 during the rotation process, thereby avoiding the influence of the fertilizer bag in the filter screen cylinder 61 on the pouring of the next bagged fertilizer.

[0023] The staff drives the driving roller 72 to rotate through the motor, and the driving roller 72, the driven roller one 73 and the driven roller two 74 are driven to rotate under the cooperation of the driving roller 72, the driven roller one 73 and the driven roller two 74. The driving roller 72, the driven roller one 73 and the driven roller two 74 drive the transmission belt 75 to rotate, and the transmission belt 75 drives the oblique stab plate 76 to rotate. When the oblique stab plate 76 touches the fertilizer bag during rotation, the oblique stab plate 76 hooks the fertilizer bag, and the fertilizer bag moves with the oblique stab plate 76 until the oblique stab plate 76 pulls the fertilizer bag to the through slot plate 79. The through slot plate 79 intercepts the fertilizer bag hooked by the oblique stab plate 76 at the through slot plate 79, thereby avoiding that the oblique stab plate 76 brings the fertilizer bag into the filter screen cylinder 61 again. At this time, the fertilizer bag can be discharged from the discharge port of the round shell 71, thereby achieving the purpose of discharging the fertilizer bag in the filter screen cylinder 61, and reducing the influence of the fertilizer bag on the discharge of the filter screen cylinder 61. The oblique stab plate 76 penetrates through the through slot plate 79.

[0024] It should be noted that the hollow setting of the I-shaped roller 78 avoids the interference of the I-shaped roller 78 on the operation of the oblique stab plate 76. During the rotation of the transmission belt 75, the transmission belt 75 also drives the I-shaped roller 78 to rotate. The I-shaped roller 78 drives the fixed sheet 782 to rotate. The fixed sheet 782 actively moves the fertilizer bag hooked by the oblique stab plate 76 to the oblique stab plate 76 during rotation, thereby helping to enhance the contact force between the fertilizer bag and the oblique stab plate 76, ensuring that the fertilizer bag can be firmly hooked, and avoiding the phenomenon of fertilizer bag slipping or falling off during movement. The two sliding blocks 781 are mainly used to support the I-shaped roller 78.

[0025] During the rotation of the driving roller 72, the driving roller 72 drives the oblong slot plate 710 to rotate. During the rotation of the oblong slot plate 710, the oblong slot of the oblong slot plate 710 pushes the slide column 715 to drive the elastic expansion rod 711 on one side to move up and down along the outer wall of the through slot plate 79. Under the cooperation of the elastic expansion rods 711 on both sides, the elastic expansion rods 711 on both sides drive the connecting plate 712 and the sharp spike 713 to move up and down. When the oblique stab plate 76 moves the fertilizer bag to the position of the through slot plate 79 each time, the sharp spike 713 inserts into the fertilizer bag, and the sharp spike 713 pulls the fertilizer bag to move downward each time the sharp spike 713 moves downward, thereby facilitating the separation of the fertilizer bag and the oblique stab plate 76. At the same time, when the connecting plate 712 moves downward and reaches the trapezoidal plate 714 position, the trapezoidal plate 714 pushes the connecting plate 712 to move away from the through slot plate 79. The connecting plate 712 drives the extension end of the elastic expansion rod 711 to stretch, and the connecting plate 712 moves with the sharp spike 713, thereby separating the sharp spike 713 and the fertilizer bag, thereby ensuring that the fertilizer bag can effectively fall at the discharge port of the round shell 71.
