DETAILED DESCRIPTION

[0018] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is merely meant to provide a better understanding of the subject matter described herein and can be changed in the function and arrangement of the elements discussed without departing from the scope of the content of this specification. Various processes or components can be omitted, substituted, or added according to various examples. In addition, features described with respect to some examples can be combined in other examples.

[0019] Please refer to Figure 1 andFigure 2 The application discloses a conveying device for loading and unloading grain, which comprises a receiving part 100, a feeding part 200, a conveying part 300, a guiding part 400, a triggering part 500 and a bag breaking and shaking part 600. The receiving part 100 comprises a support frame 110 and a hopper 120 fixed on the support frame 110. The feeding part 200 is arranged above the hopper 120 and is used for horizontally conveying a grain bag 700. The conveying part 300 is arranged below the hopper 120 and is used for conveying the grain in the hopper 120 to a discharging point. The guiding part 400 is symmetrically arranged on both sides of the hopper 120 and comprises a side plate 410 fixed on the side of the hopper 120. An annular slide is formed in the side plate 410. The triggering part 500 is movably arranged in the annular slide and is matched with the grain bag 700. The bag breaking and shaking part 600 is movably arranged in the hopper 120 and is used for puncturing and shaking the bottom of the grain bag 700. When the feeding part 200 drives the grain bag 700 to enter the loading end of the hopper 120, the triggering part 500 moves synchronously with the grain bag 700 under the action of the guiding part 400, so that the bag breaking and shaking part 600 is triggered to puncture the grain bag 700 from the bottom of the grain bag 700 and to open the punctured part to shake the grain in the grain bag 700 into the hopper 120. Specifically, the grain bag 700 filled with grain is placed on the feeding part 200 in sequence, and the feeding part 200 is used for conveying the grain bag 700 to the side of the hopper 120. During the horizontal conveying of the grain bag 700, the grain bag 700 synchronously drives the triggering part 500 to move forward along the annular slide of the guiding part 400, so that the bag breaking and shaking part 600 in the hopper 120 is triggered to protrude to the opening of the upper end of the hopper 120 by the triggering part 500, so as to puncture the grain bag 700 and puncture into the grain bag 700. With the conveying of the grain bag 700, the bag breaking and shaking part 600 gradually cuts the bottom of the grain bag 700, so that the grain in the grain bag 700 can automatically fall into the hopper 120. Then, the bag breaking and shaking part 600 opens the punctured part to the two sides, so as to shake the grain bag 700, so as to shake the residual grain in the grain bag 700 and promote the grain to be completely discharged into the hopper 120. When the grain in the grain bag 700 is discharged, the triggering part 500 is automatically separated from the grain bag 700, the feeding part 200 continues to convey the empty grain bag 700, the empty grain bag 700 is discharged from the outlet of the hopper 120, and the conveying part 300 conveys the grain in the hopper 120 to the discharging point, so as to complete the discharging.

[0020] It should be noted that, through the cooperation of the trigger 500 and the guide 400, the bag 700 pushes the trigger 500 to move along the annular slide of the guide 400 during the horizontal conveying of the feeding member 200, and the bag breaking and material shaking member 600 is automatically triggered and driven to perform the bag breaking and material shaking actions, so that the feeding of the bag 700 and the bag breaking and material shaking process are synchronized, and the bag breaking and material shaking member 600 can automatically puncture and cut the bag 700 from the bottom when the bag 700 enters the hopper 120, complete the bag breaking action, and release the grain into the hopper 120; then the bag breaking and material shaking member 600 spreads the broken part to both sides and shakes the bag 700, effectively shakes off the residual grain in the bag, and promotes the complete emptying of the grain in the bag 700.

[0021] In an embodiment, referring to Figure 3 and Figure 4 , the support frame 110 is horizontally provided with a platform 130 connected with the upper feeding end of the hopper 120 on one side, and a plurality of supporting rods 140 are rotationally arranged above the hopper 120 at equal intervals; Specifically, the bag 700 loaded with grain is placed on the platform 130, and the front end of the bag 700 can be horizontally fed to the upper part of the hopper 120 under the friction driving of the feeding member 200, and the middle part of the bag 700 is supported by the supporting rods 140, so as to avoid the middle part of the bag 700 from sagging and being separated from the feeding member 200 on both sides; during the feeding of the bag 700, the supporting rods 140 in contact with the bag 700 can also rotate synchronously with the bag 700, and in the vertical direction, each supporting rod 140 does not interfere with the movement path of the bag breaking and material shaking member 600.

[0022] Further, referring to Figure 3 , the feeding member 200 comprises driving rollers 210 rotationally installed at both ends of the hopper 120, and a conveying belt 220 is transmissionally connected between the two groups of driving rollers 210, and a driving motor (not shown in the figure) is installed on one side of the hopper 120 and connected with the driving rollers 210; Specifically, the driving rollers 210 are driven to rotate by the driving motor, so as to drive the conveying belt 220 to move synchronously, thereby realizing the horizontal pushing of the bag 700; in order to ensure the stability of the horizontal feeding of the bag 700, the conveying belt 220 can be made of rubber, so as to increase the friction between the conveying belt 220 and the bag 700, improve the horizontal dragging stability, and avoid the slipping of the bag 700.

[0023] Further, referring to Figure 3The conveying member 300 comprises a feeding pipe 310 arranged at the bottom of the hopper 120, one end of the feeding pipe 310 is communicated with the bottom of the hopper 120, and the other end of the feeding pipe 310 is provided with a discharging port 340; the feeding pipe 310 is provided with a conveying motor 320, the output end of the conveying motor 320 is connected with a spiral blade 330, and the spiral blade 330 is rotationally arranged in the feeding pipe 310; Specifically, when the grain falls into the hopper 120, the spiral blade 330 is driven to rotate by the conveying motor 320, so as to drive the grain at the bottom of the hopper 120 to enter the feeding pipe 310 and be conveyed along the spiral blade 330 to the side of the discharging port 340, until the grain is conveyed to the discharging point.

[0024] In another embodiment, please refer to Figure 4 The annular slide comprises a pushing slide 420, an ascending slide 430, a resetting slide 440 and a merging slide 450 connected in sequence; Please refer to Figure 4 and Figure 5 The triggering member 500 comprises a lower plate body 510 and an upper plate body 520 connected movably, the lower plate body 510 is provided with a pull rope 570 connected with the bag breaking and shaking member 600, and the upper plate body 520 is movably provided with a baffle 590 matched with the material bag 700; Specifically, in the initial state, the lower plate body 510 and the upper plate body 520 are attached to each other and located at the connection position of the pushing slide 420 and the merging slide 450; when the material bag 700 enters the hopper 120, the material bag 700 pushes the baffle 590, so as to drive the lower plate body 510 and the upper plate body 520 to move forward along the pushing slide 420, and then drive the bag breaking and shaking member 600 to break and shake the material bag 700 through the pull rope 570; When the grain in the material bag 700 is completely emptied into the hopper 120, the lower plate body 510 and the upper plate body 520 just reach the connection position of the pushing slide 420 and the ascending slide 430, then the upper plate body 520 moves upward along the ascending slide 430 and separates from the lower plate body 510, so that the baffle 590 is separated from the material bag 700; When the upper plate body 520 slides to the connection position of the ascending slide 430 and the resetting slide 440, the upper plate body 520 starts to slide along the resetting slide 440 arranged obliquely and resets to the connection position of the resetting slide 440 and the merging slide 450, and at the same time, the lower plate body 510 also synchronously retreats to the connection position of the pushing slide 420 and the merging slide 450 along the pushing slide 420; Finally, the upper plate body 520 slides downward along the merging slide 450 and is attached to the lower plate body 510, so as to realize the resetting of the whole triggering member 500 and drive the bag breaking and shaking member 600 to retract into the hopper 120.

[0025] It should be noted that through the segmented design of the push slide 420, the ascending slide 430, the reset slide 440 and the merging slide 450, the orderly movement of the trigger 500 is realized, so that the trigger 500 can complete the bag breaking, material shaking and resetting actions according to the preset trajectory, ensuring the automation and continuity of the whole process; the split design of the lower plate body 510 and the upper plate body 520 enables the trigger 500 to be flexibly separated and combined at different stages, realizing precise control of the bag breaking and material shaking piece 600, so that the bag breaking and material shaking piece 600 can automatically shake the grain in the bag 700 completely, avoiding grain residue; After the unloading of the bag 700 is completed, the upper plate body 520 and the lower plate body 510 can be automatically guided to separate, the upper plate body 520 moves upward along the ascending slide 430, so that the baffle 590 is separated from the empty bag 700, ensuring that the empty bag can be smoothly removed or processed, avoiding blocking the subsequent bag 700 feeding; then the two are guided to slide independently along the reset slide 440 and the push slide 420 respectively, and finally reattach at the merging slide 450; when the lower plate body 510 retreats along the push slide 420, the inhaul cable 570 on it synchronously drives the bag breaking and material shaking piece 600 to retract into the hopper 120, preparing for the feeding and bag breaking of the next bag 700 and avoiding interference; The reset slide 440 is designed to be inclined, and after the upper plate body 520 reaches the top end thereof, it can automatically slide down along the inclined reset slide 440 to the starting point of the merging slide 450 by gravity; at the merging slide 450, the sliding down upper plate body 520 reattaches with the reset lower plate body 510, so that the trigger 500 returns to the initial merging state, and the bag breaking and material shaking piece 600 is completely retracted, and the system is automatically reset, and the next bag 700 processing process can be triggered immediately.

[0026] Further, please refer to Figure 6 , in order to realize the automatic separation of the lower plate body 510 and the upper plate body 520, a cavity 530 is formed in the lower plate body 510, a first guide rod 540 is vertically fixed in the cavity 530, the upper plate body 520 is slidably sleeved on the first guide rod 540, and a first spring 550 abutting against the upper plate body 520 is arranged in the cavity 530; Specifically, when the material bag 700 pushes the baffle 590 to feed forward, the lower plate body 510 and the upper plate body 520 move forward along the pushing slide 420 together, at this time, the upper plate body 520 is always attached to the lower plate body 510 due to the limitation of the pushing slide 420, until the lower plate body 510 and the upper plate body 520 reach the connection position of the pushing slide 420 and the ascending slide 430, at this time, the upper plate body 520 is no longer limited by the pushing slide 420 above, and can move upward along the first guide rod 540 under the elastic force of the first spring 550, so that the upper plate body 520 slides upward along the ascending slide 430, to realize the temporary separation of the upper plate body 520 and the lower plate body 510, at this time, the baffle 590 also rises with the upper plate body 520 and is separated from the material bag 700, so that the empty material bag 700 after discharging the grain is moved away from the side of the hopper 120 far from the conveying belt 220; then the upper plate body 520 slides along the inclined reset slide 440 under the action of gravity, and drives the lower plate body 510 to slide along the pushing slide 420 synchronously, until the upper plate body 510 slides to the connection position of the reset slide 440 and the merging slide 450.

[0027] It should be noted that when the lower plate body 510 and the upper plate body 520 move to the connection position of the pushing slide 420 and the ascending slide 430, the upper plate body 520 is no longer limited by the pushing slide 420, and the elastic force of the first spring 550 is released instantaneously, pushing the upper plate body 520 to vertically upwardly eject along the first guide rod 540, so that it quickly enters the ascending slide 430, realizing efficient separation from the lower plate body 510; the first guide rod 540 is vertically fixed in the cavity 530, providing precise vertical guidance for the upper plate body 520, avoiding deflection or jamming during the ejection process, and ensuring stable and reliable sliding trajectory along the ascending slide 430; In the pushing stage, the side wall of the pushing slide 420 forces the upper plate body 520 and the lower plate body 510 to keep close attachment, ensuring the overall synchronous movement of the two; when reaching the slide connection position, the limitation is released synchronously with the spring release, realizing the automatic ejection of the upper plate body 520; when the upper plate body 520 is ejected upward, the baffle 590 is lifted synchronously, so that it is instantaneously separated from the empty material bag 700, ensuring that the empty bag can be immediately moved out, avoiding hindering the feeding of the subsequent material bag 700.

[0028] Further, please refer to Figure 4 and Figure 5 , considering that during the reset process, the sliding reset of the upper plate body 520 and the lower plate body 510 is only realized by the gravity of the upper plate body 520 itself, which may affect the smoothness of the reset process due to the large moving resistance during the sliding reset process; therefore, a second guide rod 460 is horizontally fixed in the pushing slide 420, the lower plate body 510 is slidingly sleeved on the second guide rod 460, and a second spring 470 abutting against the lower plate body 510 is movably sleeved on the second guide rod 460; Specifically, when the lower plate body 510 and the upper plate body 520 are moved along the pushing slide 420 synchronously with the material bag 700, the second spring 470 is compressed to store energy, and when the pushing slide 420 and the rising slide 430 are connected, the upper plate body 520 and the lower plate body 510 are separated, the whole trigger 500 is no longer limited by the material bag 700, and the lower plate body 510 can slide along the pushing slide 420 to reset automatically under the elastic force of the second spring 470, and the upper plate body 520 is synchronously slid along the reset slide 440 to reset.

[0029] It should be noted that when the material bag 700 pushes the trigger 500 along the pushing slide 420, the lower plate body 510 synchronously compresses the second spring 470 to store energy, and when the unloading is completed and the upper plate body 520 is separated, the lower plate body 510 is quickly returned under the elastic force of the second spring 470, and the sliding resistance is overcome to ensure that the reset is rapid and reliable. The lower plate body 510 is sleeved on the second guide rod 460 to obtain precise horizontal guidance, and the reset is prevented from being skewed or stuck; the strong pushing force of the second spring 470 directly offsets the moving resistance, and the delay problem that may occur in the pure gravity reset is completely solved. The spring-driven reset of the lower plate body 510 and the gravity sliding reset of the upper plate body 520 are synchronously performed, the lower plate body 510 is horizontally returned to the starting point along the second guide rod 460, and the upper plate body 520 is obliquely slid to the merging position along the reset slide 440; the rapid and reliable reset ensures that the trigger 500 and the bag breaking and material shaking device 600 quickly recover to the initial state, and sufficient response time is left for the feeding and triggering of the next material bag 700.

[0030] In addition, please refer to Figure 4 and Figure 6 , in order to realize the automatic merging of the upper plate body 520 and the lower plate body 510, the vertical cylinder 480 is installed in the side plate 410, the cylinder 480 is located directly above the merging slide 450, and the output end of the cylinder 480 is connected with the pushing plate 490 matched with the upper end surface of the upper plate body 520; Specifically, when the upper plate body 510 slides to the merging slide 450 and the reset slide 440 is connected, the lower plate body 510 also slides to the merging slide 450 and the pushing slide 420 is connected, and at this time, the pushing plate 490 is driven to vertically descend along the merging slide 450 by the cylinder 480, the upper plate body 520 is vertically pushed downward, the upper plate body 520 is slid downward along the merging slide 450 until the upper plate body 520 is attached to the lower plate body 510, the first spring 550 is compressed, and the baffle 590 is also lowered to the initial height, so that the lower plate body 510 and the upper plate body 520 as a whole are pushed along the pushing slide 420 by the next material bag 700.

[0031] It should be noted that the air cylinder 480 drives the push plate 490 to vertically press down along the merging slide 450, and exerts a vertical downward thrust on the upper plate body 520 located at the slide connection, so as to ensure that the upper plate body 520 strictly slides along the slide track and closely abuts against the lower plate body 510, and overcomes the resistance of the first spring 550 to complete the locking; During the pressing-down process, the upper plate body 520 compresses the first spring 550 in the cavity 530, so that the first spring 550 restores the energy storage state, reserves the elastic force for the next separation action, and ensures the instantness of the subsequent triggering separation; the downward movement of the upper plate body 520 synchronously drives the baffle 590 to descend to the preset initial position, so that the baffle 590 is accurately aligned with the feeding path of the next bag 700, and is ready for continuous triggering.

[0032] In further embodiments, please refer to Figure 3 and Figure 7 The bag breaking and material shaking member 600 includes mounting plates 610 symmetrically fixed to the inner walls on both sides of the hopper 120, vertical sliding grooves 620 and horizontal sliding grooves 630 are formed on the mounting plates 610 and are spliced with each other, a sliding table 640 is movably mounted on the mounting plates 610, sliding pins 650 are arranged at both ends of the sliding table 640 and are adapted to the vertical sliding grooves 620 and the horizontal sliding grooves 630, one end of the sliding table 640 is connected with the pull cable 570, a sleeve rod 660 is rotatably mounted at the other end of the sliding table 640, blades 680 are vertically mounted on the sleeve rod 660, an extension rod 670 is slidably connected between the sleeve rods 660, and a tension spring (not shown in the figure) connected with the extension rod 670 is arranged in the sleeve rod 660; Specifically, in the initial state, the sliding table 640 is in a vertical posture, at this time, the sliding pins 650 at both ends of the sliding table 640 are located in the vertical sliding grooves 620; when the trigger member 500 follows the horizontal feeding of the bag 700, the sliding table 640 can be pulled by the pull cable 570, and the sliding table 640 can move upward along the vertical sliding grooves 620 under the action of the vertical component force of the pull cable 570, and simultaneously drives the two blades 680 to synchronously rise, so that the blades 680 can be inserted into the bag 700 from the bottom of the bag 700, and gradually cut a discharging notch at the bottom of the bag 700 by using the blades 680 along with the horizontal feeding of the bag 700; With the continuous feeding of the trigger 500, the upper end slide pin 650 of the slide table 640 begins to gradually transition from the vertical slide groove 620 into the horizontal slide groove 630, and then under the horizontal component force of the pull cable 570, the slide table 640 gradually flips and switches from a vertical posture to a horizontal posture, until the slide pin 650 at the lower end also transitions into the horizontal slide groove 630. During the flipping process, the two side blades 680 also gradually move away in the horizontal direction, and the telescopic rod 670 extends out of the two side sleeves 660. The tension spring is stretched and stored, and the blades 680 that move away from each other are used to stretch the cutout at the bottom of the bag 700 to the two sides, so as to promote the discharge of the grain inside the bag 700 and generate a shaking effect on the bag 700, avoiding grain residue. When the discharge is completed, the trigger 500 is reset, the pull cable 570 no longer pulls the slide table 640, and the two slide tables 640 can move close to each other under the tension of the tension spring, until the slide pins 650 at both ends of the slide table 640 again enter the vertical slide groove 620, and then the two slide tables 640 can fall back to the vertical slide groove 620 under the action of gravity, so that the two blades 680 retract into the hopper 120.

[0033] It should be noted that through the splicing path of the vertical slide groove 620 and the horizontal slide groove 630, the slide table 640 moves in two stages under the traction of the pull cable 570; in the first stage (i.e., vertical puncture), the slide pin 650 slides along the vertical slide groove 620, driving the blade 680 to vertically rise and pierce into the bottom of the bag 700 and cut an opening; in the second stage (i.e., horizontal stretching), the slide pin 650 transitions to the horizontal slide groove 630, the slide table 640 flips to a horizontal posture, driving the two side blades 680 to horizontally move out, and the telescopic rod 670 extends out to stretch the opening; then the tension spring retracts to move the double slide tables 640 towards each other, generating a shaking effect on the bag 700, completely emptying the grain, while the slide pin 650 exits the horizontal slide groove 630, and the slide table 640 slides down along the vertical slide groove 620 under the action of gravity, driving the blade 680 to retract into the hopper 120.

[0034] Further, please refer to Figure 4 In order to enable the pull cable 570 to drive the slide table 640 to vertically rise along the vertical slide groove 620 and then slide horizontally along the horizontal slide groove 630, it is necessary to ensure that the pull cable 570 can always exert an inclined upward tension on the slide table 640. For this purpose, a guide wheel 121 and a sleeve ring 122 are installed in sequence on the inner wall of the hopper 120, one end of the pull cable 570 is fixedly connected to the lower plate body 510 by passing through the guide wheel 121, and the other end of the pull cable 570 passes out of the sleeve ring 122 and is fixedly connected to the slide table 640. Specifically, the installation height of the guide wheel 121 and the sleeve ring 122 is higher than the horizontal sliding groove 630, so that the pulling force of the pull rope 570 on the sliding table 640 can always be decomposed into a vertical component and a horizontal component; when the sliding table 640 is located in the vertical sliding groove 620, the vertical component can drive the sliding table 640 to vertically rise, and when the sliding table 640 reaches the transition between the vertical sliding groove 620 and the horizontal sliding groove 630, the horizontal component can drive the sliding table 640 to smoothly enter the horizontal sliding groove 630 from the vertical sliding groove 620 and continue to move along the horizontal sliding groove 630.

[0035] It should be noted that the pull rope 570 is always formed to be obliquely pulled on the sliding table 640 through the steering support of the guide wheel 121 and the limiting and guiding of the sleeve ring 122, and the installation height of the guide wheel 121 and the sleeve ring 122 is higher than the horizontal sliding groove 630, so that the pulling force direction is always constant and inclined upward; The oblique pulling force can be continuously decomposed into a vertical component and a horizontal component, the vertical component can drive the sliding table 640 to vertically rise along the vertical sliding groove 620 when the sliding table 640 is located in the vertical sliding groove 620, so as to realize the puncture action of the blade 680; and the horizontal component can push the sliding pin 650 to smoothly cut into the horizontal sliding groove 630 from the vertical sliding groove 620 when the sliding table 640 moves to the transition between the vertical sliding groove 620 and the horizontal sliding groove 630, so as to ensure that the posture switching is not stuck and realize the shaking action of the blade 680. The sleeve ring 122 restricts the pulling end of the pull rope 570, avoids swinging of the pulling end in the overturning process of the sliding table 640, ensures that the pulling force direction is always consistent with the preset direction, and forces the sliding table 640 to strictly move along the composite path from the vertical sliding groove 620 to the horizontal sliding groove 630.

[0036] Further, please refer to Figure 8 and Figure 9 , considering that if the placement posture of the material bag 700 is not correct in the horizontal feeding process, the subsequent incision cannot be guaranteed to be centered, thereby affecting the smooth emptying of the grain in the material bag 700; therefore, the horizontal sliding cavity 521 and the vertical sliding cavity 522 that are in communication with each other are formed in the upper plate body 520, the sliding plate 560 is slidingly installed in the horizontal sliding cavity 521, and the two sliding plates 560 are fixedly connected with the baffle 590; the third guide rod 523 is vertically fixed in the vertical sliding cavity 522, the catch pin 580 is slidingly sleeved on the third guide rod 523, the third spring 524 that abuts against the catch pin 580 is movably sleeved on the third guide rod 523, and the clamping groove 491 that is adapted to the catch pin 580 is formed in the lower end surface of the push plate 490; the pull rope 526 is connected between the catch pin 580 and the sliding plate 560, and the guide roller 525 that is adapted to the pull rope 526 is rotatably installed at the joint between the horizontal sliding cavity 521 and the vertical sliding cavity 522; Specifically, in the initial state, due to the elastic force of the third spring 524, the catch 580 is popped up along the vertical sliding cavity 522 and embedded into the clamping groove 491 of the push plate 490, so that the upper plate body 520 and the lower plate body 510 cannot slide horizontally along the push sliding channel 420 due to the mutual locking of the catch 580 and the clamping groove 491; When the bag 700 is placed in an incorrect posture, one side of the front end of the bag 700 is necessarily closer to the front, and the other side is necessarily closer to the rear. Under the driving of the feeding member 200, the side of the bag 700 closer to the front will first contact the baffle 590, thereby pushing the sliding plate 560 on the same side to slide along the corresponding horizontal sliding cavity 521, and further driving the catch 580 to slide downward along the third guide rod 523 and retract into the vertical sliding cavity 522 under the pulling of the pull rope 526, until the catch 580 is disengaged from the clamping groove 491, thereby realizing the horizontal unlocking between the upper plate body 520 and the push plate 490 on the same side; At this time, the side of the bag 700 closer to the rear has not contacted the baffle 590, thereby failing to push the sliding plate 560 on the same side, and further failing to horizontally unlock the upper plate body 520 on the same side. In this way, the entire baffle 590 remains in the initial position, and the side of the bag 700 closer to the front cannot continue to be fed forward along with the conveying belt 220 due to the blocking of the baffle 590, while the side of the bag 700 closer to the rear can be fed forward under the driving of the conveying belt 220, until the side of the bag 700 closer to the rear also contacts the baffle 590, thereby pushing the sliding plate 560 on the same side and horizontally unlocking the upper plate body 520 on the same side. At this time, the bag 700 is just corrected and aligned, and the two sides of the front end of the bag 700 are flush. After the horizontal unlocking of the upper plate bodies 520 on both sides, the baffle 590 can be horizontally moved under the pushing of the bag 700, thereby triggering the bag-piercing and material-shaking action of the bag-piercing and material-shaking member 600.

[0037] It should be noted that when the front end of the bag 700 is skewed, the side first contacting the baffle 590 pushes the sliding plate 560, pulls the catch 580 on the same side away from the clamping groove 491 through the pull rope 526, but the other side is still locked. The skewed side is blocked by the baffle 590 and cannot advance, and the rear side continues to be pushed by the feeding member 200 until it contacts the baffle 590 and unlocks the catch 580 on the other side, thereby forcing the bag 700 to automatically align to the flush state of both sides. When the bag 700 is skewed, the leading side pushes the corresponding sliding plate 560 to slide along the horizontal sliding cavity 521, and the pull rope 526 guided by the guide roller 525 pulls the catch 580 on the same side to compress the third spring 524 and slide downward along the third guide rod 523, thereby disengaging from the clamping groove 491 of the push plate 490 and realizing the horizontal unlocking on the same side. The non-contact side latch 580 is kept in a pop-up state under the action of the third spring 524, is clamped into the card slot 491, and makes the upper plate body 520 still be horizontally locked; the baffle 590 cannot be moved as a whole, forcibly blocks the advanced side bag 700, and allows the whole to feed only after the lag side bag 700 is in place and pushes the unlocking, ensures that the front end of the bag 700 is completely aligned with the baffle 590 before triggering the feeding, so that the puncture incision position of the subsequent blade 680 is centered, and food residues or incomplete emptying caused by the incision deviation are avoided.

[0038] The application further provides a conveying method of the conveying equipment for loading and unloading grain, comprising the following steps: Step one, the bag 700 filled with grain is placed on the feeding piece 200 in sequence, and the bag 700 is conveyed to the side of the hopper 120 through the feeding piece 200; Step two, the bag 700 pushes the trigger piece 500 to feed along the annular slide of the guide piece 400, the trigger piece 500 triggers the bag breaking and material shaking piece 600 in the hopper 120 to pierce the bag 700 and cut an incision; Step three, the bag breaking and material shaking piece 600 spreads the broken part to both sides, shakes the bag 700, and promotes the grain in the bag 700 to be discharged into the hopper 120; Step four, the conveying piece 300 conveys the grain in the hopper 120 to a discharge point, and the discharging is completed.
