Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bulk grain packaging, and in particular to a ton bag self-unloading device. BACKGROUND

[0002] Bulk grains such as wheat and rice are generally transported over long distances by agricultural vehicles, and then packaged into ton bags that can hold a large amount of bulk grain for distribution. The traditional method of unloading grain is to directly rotate the raised rear compartment of the agricultural vehicle, pour the grain onto the ground, and then manually shovel it into the ton bag. Alternatively, the worker can directly shovel the grain on the vehicle into the ton bag placed below the outlet of the rear compartment.

[0003] A more convenient unloading mechanism is to place a screw conveyor in the rear compartment of the vehicle. The worker continuously sweeps the bulk grain into the inlet of the screw conveyor, and the outlet of the screw conveyor extends outside the vehicle. The worker needs to open the ton bag and place it below the outlet of the screw conveyor, and the bulk grain will automatically fall into the ton bag.

[0004] However, the above unloading mechanism still requires a large number of workers to operate. When a ton bag is full, the screw conveyor needs to be stopped, a forklift needs to be driven to the ton bag full of bulk grain, the worker needs to place the handle of the ton bag on the two forks of the forklift, and the full ton bag needs to be forked away by the forklift. Then, an empty ton bag needs to be placed under the screw conveyor to continue unloading the grain. This process is time-consuming and labor-intensive, and reduces the work efficiency. SUMMARY

[0013] By adopting the technical scheme, the control assembly is specifically provided as a rotatable baffle, the switching of the first channel and the second channel can be realized only by rotating the guide column, the operation is convenient and fast, and when the baffle blocks one channel, the baffle is arranged to be inclined upward away from the hinged position and abuts against the inner wall of the housing, the force of the bulk grain falling from the discharging pipe on the baffle drives the baffle to rotate towards the blocked channel, so that the baffle can stably block the channel and realize the separate bagging of the bulk grain without stopping the lifting mechanism.

[0014] Optionally, the guide column is connected with a cover plate used for sealing the arc-shaped slot.

[0015] By adopting the technical scheme, the guide column is further connected with a cover plate which can move together with the guide column, the area of the cover plate can be set to be relatively large so as to always seal the arc-shaped slot, thereby avoiding the possibility of the bulk grain falling out of the housing from the arc-shaped slot, avoiding the waste of grain or increasing the workload.

[0016] Optionally, the insertion slot penetrates both ends of the horizontal rod along the length direction of the horizontal rod, a driving block is slidably connected in the insertion slot, and a connecting rod is movably connected between the guide column and the driving block.

[0017] By adopting the technical scheme, the slot is arranged to be communicated with the whole cross bar, when the fork enters the slot from one side of the cross bar, the driving block is pushed to move, so that the guide column is driven to move along the arc-shaped slot through the connecting rod, and then the baffle is rotated to the sealed channel towards the channel of the forklift entering side to open the other channel, so that the bulk grain enters the empty ton bag on the other side. The baffle is automatically switched during the forklift bagging process, which is more convenient and fast to operate, and no additional staff is needed to operate the control assembly, only one staff is needed to control the forklift, which further improves the efficiency of bulk grain bagging.

[0018] Optionally, a rotating shaft for rotating the baffle is arranged in the shell, the rotating shaft penetrates out of the shell and is rotationally connected with the connecting rod, a movable slot is arranged on the lower end of the connecting rod through the cross bar and along the length direction of the connecting rod, and a limiting slot along the length direction is arranged on the side wall of the cross bar along the length direction, and the driving block is provided with a driving column penetrating through the limiting slot and the movable slot.

[0019] By adopting the technical scheme, the rotating shaft of the baffle penetrates out and is rotationally connected with the connecting rod, so that the connecting rod has a rotating fulcrum, and the stability of the rotating process of the connecting rod is improved, when the driving block is driven to slide by the fork, the driving of the connecting rod can be realized through the driving column penetrating through the cross bar and the connecting rod, so that the connecting rod can rotate around the rotating shaft, so that the guide column can slide in the arc-shaped slot to drive the baffle to rotate, the switching of the first channel and the second channel is realized, the possibility of the guide column being jammed in the arc-shaped slot is reduced, the smoothness of switching the bulk grain outlet is ensured, and the efficiency of bulk grain bagging is improved.

[0020] Optionally, two positioning components are arranged on the cross bar at intervals, the positioning component comprises a positioning block in vertical sliding connection with the cross bar, the cross bar is provided with a first clearance hole for the positioning block to penetrate at the bottom wall of the slot, the positioning block is connected with an elastic member for driving the positioning block to move upwards, and the opposite sides of the two positioning blocks are inclined downward towards each other; when the baffle closes the first channel or the second channel, the side of the positioning block away from the other positioning block abuts against the driving block, and the positioning block is used for limiting the movement of the driving block.

[0021] By adopting the technical scheme, when the fork pushes the driving block to move from one end of the cross rod to the proximity of the limit position of the rotation of the baffle, the driving block abuts against the inclined surface of the positioning block at the other end, and as the driving block continues to move, the positioning block is gradually pressed downward to be flush with the bottom wall of the insertion slot, then the fork continues to push the driving block to move forward until the baffle reaches the limit position, at this time, the fork moves back by a distance to avoid lifting the empty ton bag, then the elastic member drives the positioning block to move upward into the insertion slot and abut against the driving block, so as to limit the movement of the driving block back, that is, to limit the rotation of the baffle, so that the bagging process of bulk grain is more stable, and the accuracy of ton bag packaging is also improved.

[0022] Optionally, the positioning component further comprises an unlocking block connected with the positioning block, when the positioning block abuts against the driving block, the unlocking block abuts against the side of the driving block away from the positioning block, the cross rod is provided with a second clearance hole for the unlocking block to pass through at the bottom wall of the insertion slot, and the side of the unlocking block away from the positioning block is inclined downward away from the positioning block.

[0023] By adopting the technical scheme, the positioning block is further connected with the unlocking block, when the fork enters the insertion slot, the unlocking block is first pushed downward by the inclined surface of the unlocking block, and then the positioning block is driven to move downward together to release the locking of the driving block, so that the fork can directly adjust and lock the baffle during lifting of the ton bag, and the staff does not need to additionally unlock the positioning block, and the efficiency of bulk grain bagging is further improved.

[0024] Optionally, the first and second discharge pipes have first and second discharge openings, the first and second discharge openings are movably connected with first and second sealing plates respectively, the first and second sealing plates are controlled by the same driving component, and the driving component is used to control the first and second sealing plates to open and close the first and second discharge openings; when the driving component controls the first sealing plate to close the first discharge opening, the second sealing plate opens the second discharge opening, and when the driving component controls the second sealing plate to close the second discharge opening, the first sealing plate opens the first discharge opening.

[0025] By adopting the technical scheme, as the baffle gradually seals the first channel or the second channel during the rotation and closing process, the bulk grain passes through the first channel or the second channel at the same time, and the sealing plates are arranged at the discharge openings of the first and second channels. Taking the case that the baffle needs to close the first channel and open the second channel as an example, the first discharge opening is closed and the second discharge opening is opened before adjusting the baffle, so as to limit the bulk grain from continuing to fall into the ton bag that has been filled, and the accuracy of ton bag packaging is further improved; then the baffle is rotated to close the first channel, and during the rotation of the baffle, the first channel can be used as a temporary storage bin.

[0026] Optionally, the first sealing plate and the second sealing plate are respectively hinged in the first channel and the second channel, and the hinged positions of the first sealing plate and the second sealing plate face towards each other; the driving component includes a control rack, and the first discharge pipe and the second discharge pipe have a first through groove and a second through groove respectively below the hinged position of the first sealing plate and the second sealing plate for the two ends of the control rack to pass through. The two ends of the control rack can respectively abut against and drive the first sealing plate and the second sealing plate to rotate to close the first discharge port and the second discharge port. Two gears that mesh with the control rack are respectively rotatably connected to the first discharge pipe and the second discharge pipe, and a transmission component that can control the rotation of the gears is connected to the crossbar.

[0027] By adopting the above technical solution, the driving component is specifically configured as a meshing gear and a control rack. The gear meshes with a transmission component located on the crossbar. When the fork enters the slot of the crossbar, it drives the transmission component to move, thereby driving the gear to rotate. The control rack converts the rotation of the gear into linear movement. For example, when one end of the control rack enters the first channel through the first through slot, the other end will disengage from the second channel through the second through slot, that is, disengage from the second sealing plate, causing the second sealing plate to rotate downward under the force of gravity until the second discharge port is opened. Since the control rack abuts against the rotating end of the first sealing plate, it only needs to move a small distance to drive the first sealing plate to rotate to close the first discharge port, so as to realize the rapid opening and closing of the first and second discharge ports.

[0028] Optionally, the teeth of the control rack are disposed on the bottom surface of the control rack, and the transmission component includes a drive end that slides vertically through the bottom wall of the slot and a transmission end that meshes vertically with the gear on the side opposite to the other gear. The drive end is located on the crossbar and on the side of the unlocking block away from the positioning block, and the side of the drive end opposite to the unlocking block is inclined downward in the direction away from the unlocking block.

[0029] By adopting the above technical solution, the transmission component is specifically configured as a movable fork pressing against the moving part. When the transmission component moves, it drives the gear transmission through the transmission end, thereby driving the control rack to move to control the opening and closing of the first discharge port and the second discharge port. Moreover, the driving end of the transmission component is set at the front end of the drive block. The fork first drives the first sealing plate and the second sealing plate to move and then drives the baffle to rotate, thereby realizing the rapid stopping of the discharge of loose grain and the reversal of the discharge direction.

[0030] In summary, this application includes at least one of the following beneficial effects:

[0031] 1. When bagged, the rear compartment of the agricultural vehicle is tilted up to directly pour the bulk grain into the lower receiving hopper, and the bulk grain in the receiving hopper is lifted by the lifting mechanism and directly discharged into the ton bag. When a ton bag is full, the forks of the forklift can be directly inserted into the ton bag handle through the slot, and then the forks are lifted to directly fork the ton bag away, without manual shoveling and bagging, saving time and effort, and reducing production cost;

[0032] 2. During the process of the forks entering the slot, the baffle will be driven to rotate by the driving block to change the first channel or the second channel, and the bulk grain will directly fall into the new ton bag through the opened channel, and then only the new empty ton bag needs to be placed on the bag support frame on the side where the ton bag is removed, waiting for the next turning and bagging. The entire grain loading process does not need to stop the lifting mechanism, improving the grain loading efficiency;

[0033] 3. When the forks just enter the slot, the driving component will immediately stop the bulk grain from falling into the full ton bag, thereby improving the accuracy of ton bag packaging. BRIEF DESCRIPTION OF DRAWINGS

The auxiliary mechanism comprises a winch and a scraper, the scraper is connected to the traction rope of the winch, and the bulk grain in the rear compartment is scraped clean by continuously adjusting the position of the scraper by one worker.

[0044] The embodiment is preferably arranged in an agricultural vehicle that can automatically tilt and lift the rear compartment. Referring to Figure 1, the width of the upper end opening of the receiving hopper 1 is not less than the width of the rear compartment, the lifting mechanism 2 can be a bucket elevator or a dragon, preferably a dragon, the dragon includes a tube 23 placed obliquely and a spiral paddle arranged in the tube 23, the lower end of the tube 23 is provided with a feeding pipe 21 connected with the lower end outlet of the receiving hopper 1, and the upper end of the tube 23 is provided with a discharging pipe 22 arranged vertically downward. When bagging, the rear compartment of the agricultural vehicle is tilted up to directly pour the bulk grain into the receiving hopper 1 below, and the bulk grain enters the lifting mechanism 2 from the lower end of the receiving hopper 1 and is discharged from the discharging pipe 22.

[0045] With reference to Figure 1 and Figure 3 , the distributing mechanism 3 includes a housing 4, a control assembly 5 and a bag supporting frame 6, the housing 4 includes a first discharging pipe 41 and a second discharging pipe 42 in communication with the discharging pipe 22 and respectively formed with a first passage 411 and a second passage 421, the control assembly 5 is used to control the opening and closing of the first passage 411 and the second passage 421, and the bag supporting frame 6 includes two horizontal rods 61 arranged on both sides of the line connecting the first discharging pipe 41 and the second discharging pipe 42 and vertical rods used to support the horizontal rods 61, the middle part of the two horizontal rods 61 is connected with a reinforcing rod, and the reinforcing rod separates the horizontal rods 61 to form a first bagging unit 611 and a second bagging unit 612 corresponding to the positions below the first discharging pipe 41 and the second discharging pipe 42, the number of ton bags is two, the handles of the two ton bags are respectively hung at the positions of the first bagging unit 611 and the second bagging unit 612 of the horizontal rods 61, and the top surface of the horizontal rods 61 is provided with a slot 613 along the length direction for the entry of the forks of a forklift, and the horizontal rods 61 can be directly processed from a channel steel. For example, the control assembly 5 can first close the second passage 421 and open the first passage 411, the bulk grain passes through the first passage 411 and is discharged from the lower end of the first discharging pipe 41 to directly fall into the ton bag placed in the first bagging unit, when the ton bag is full, the forks of the forklift can directly insert into the handle of the ton bag below through the slot 613, and then the forks lift to carry away the ton bag, at this time, the control assembly 5 closes the first passage 411 and opens the second passage 421, and the bulk grain directly falls into the ton bag in the second bagging unit through the second passage 421, then only needs to place a new empty ton bag at the first bagging unit position of the horizontal rods 61, and waits for the next time of turning to bag, the whole grain loading process does not need to stop the lifting mechanism 2, and the number of required workers is reduced, the grain loading efficiency is improved, and the production cost is reduced.

[0046] In other embodiments, the control assembly 5 can be two sliding plates respectively slidably connected with the first discharging pipe 41 and the second discharging pipe 42, and the first passage 411 and the second passage 421 are respectively opened and closed by sliding the two sliding plates towards the housing 4 or away from the housing 4, so as to control the bulk grain to fall into different ton bags.

[0047] In this embodiment, in order to further improve the work efficiency, with reference toFigure 3 And Figure 4 The control assembly 5 comprises a rotating shaft 56 hinged to the housing 4 at the communication position between the first channel 411 and the second channel 421, and a baffle 51 fixed to the rotating shaft 56, the baffle 51 being capable of rotating to close the first channel 411 or the second channel 421, and abutting against a vertical position in the housing 4 connected to the discharge pipe 22 when the baffle 51 rotates to close the first channel 411 or the second channel 421 to limit the baffle 51 from continuing to rotate. The baffle 51 is connected with a guide column 52 penetrating the housing 4, and the housing 4 is provided with an arc-shaped slot 43 for the guide column 52 to move. Further, the guide column 52 is connected with a cover plate 53 for sealing the arc-shaped slot 43, the cover plate 53 is preferably an arc-shaped plate with an arc greater than twice the arc of the arc-shaped slot 43, and the middle part of the cover plate 53 is fixed to the guide column 52 and attached to the outer wall of the housing 4, so as to avoid the possibility of the bulk grain falling out of the housing 4 from the arc-shaped slot 43, and to avoid wasting grain or increasing workload. It should be noted that when the baffle 51 blocks one of the channels, it is inclined upward away from the rotating shaft 56 and abuts against the inner wall of the housing 4, and the force of the bulk grain falling from the discharge pipe 22 on the baffle 51 drives the baffle 51 to rotate in the direction of the blocked channel, so that the baffle 51 can stably block the channel, realizing the bulk grain bagging packaging without stopping the lifting mechanism 2

[0048] In other embodiments, the staff can directly rotate the guide column 52 to switch the first channel 411 and the second channel 421, which is convenient and fast.

[0049] In this embodiment, in order to further improve the convenience of operation, the two inner walls of the housing 4 abutting against the baffle 51 are both provided with guide columns 52, and the two guide columns 52 are both connected with linkage assemblies, so that the rotation and switching of the baffle 51 can be realized by the forks of the forklift. Specifically, referring to Figure 3 And Figure 4The linkage assembly comprises a driving block 54 and a connecting rod 55, the insertion slot 613 is a long slot penetrating through both ends of the cross bar 61 along the length direction of the cross bar 61, the driving block 54 is slidingly connected in the insertion slot 613, the guide column 52 is fixedly connected with one end of the connecting rod 55, the rotating shaft 56 also penetrates out of the shell 4 and is rotatably connected with the connecting rod 55, the driving block 54 is movably connected with the end of the connecting rod 55 away from the guide column 52, the rotating lower end of the connecting rod 55 passes by the cross bar 61 and is provided with a movable slot 551 along the length direction of the connecting rod 55, the side wall of the cross bar 61 along the length direction is provided with a limiting slot 614 along the length direction, the driving block 54 is provided with a driving column 541 penetrating through the limiting slot 614 and the movable slot 551, and one end of the driving column 541 penetrating through the connecting rod 55 is provided with a limiting ring with a diameter larger than the width of the movable slot 551, so as to avoid the disconnection between the driving block 54 and the connecting rod 55. When the forks enter the insertion slot 613 from one side of the cross bar 61, the driving block 54 is pushed to move, so that the connecting rod 55 can rotate around the rotating shaft 56, so that the guide column 52 can slide in the arc-shaped slot 43 to drive the baffle 51 to rotate, the switching of the first channel 411 and the second channel 421 is realized, the bulk grain enters the ton bag on the other side, then the forks lift the ton bag to carry away, the forklift automatically switches the baffle 51 in the process of carrying the bag, the operation is more convenient and fast, and it is unnecessary to additionally operate the control assembly 5, only one worker is needed to control the forklift, and the efficiency of the bulk grain bagging is further improved.

[0050] With reference to Figure 5In order to make the process of bulk grain bagging more stable, two positioning components 57 are arranged on the horizontal rod 61 at intervals, which are used to limit the movement of the driving block 54 when the baffle 51 is rotated to close the first channel 411 or the second channel 421. Specifically, the positioning component 57 comprises the positioning block 571 and the unlocking block 572 arranged at intervals, the distance between the positioning block 571 and the unlocking block 572 is not less than the length of the driving block 54, the side of the positioning block 571 and the unlocking block 572 away from each other is inclined downward, the positioning block 571 and the unlocking block 572 are vertically slidably connected with the horizontal rod 61, the positions of the positioning block 571 and the unlocking block 572 below the horizontal rod 61 are connected by a connecting rod, the horizontal rod 61 is provided with the first clearance hole 615 and the second clearance hole 616 for the positioning block 571 and the unlocking block 572 to pass through at the bottom wall of the slot 613, the bottom of the connecting rod is provided with a stand, the bottom surface of the horizontal rod is provided with a connecting frame for the vertical movement of the stand, the stand is sleeved with the elastic member 573 for driving the positioning block 571 to move upward, and the elastic member 573 is preferably a spring. When the baffle 51 closes the first channel 411 or the second channel 421, the side of the positioning block 571 away from the other positioning block 571 abuts against the driving block 54, and the positioning block 571 is used to limit the movement of the driving block 54. In the initial state, the elastic member 573 drives the positioning component 57 to move upward, and the driving block 54 is located between the positioning block 571 and the unlocking block 572; when the fork enters the slot 613, the unlocking block 572 is first pushed downward by the inclined surface of the unlocking block 572, and then the positioning block 571 is driven to move downward together to the top to be flush with the bottom wall of the slot 613, and then the fork continues to push the driving block 54 to move forward until the driving block 54 presses the other positioning block 571, at this time, the baffle 51 reaches the limit position, and the driving block 54 cannot continue to move, at this time, the fork moves back by a distance to avoid lifting the handle of the empty ton bag, and then the elastic member 573 drives the other positioning block 571 to move upward into the slot 613 and abut against the driving block 54 in the plane, so as to limit the movement of the driving block 54 back, that is, to limit the rotation of the baffle 51, so that the bulk grain can stably fall into the empty ton bag, and the accuracy of ton bag packaging is improved.

[0051] Because the baffle 51 gradually seals the first channel 411 or the second channel 421 in the process of rotating and closing, the first discharge pipe 41 and the second discharge pipe 42 have the first discharge port 412 and the second discharge port 422, at this time, the bulk grain will pass through the first channel 411 or the second channel 421 and fall from the first discharge port 412 and the second discharge port 422, in order to further improve the accuracy of ton bag packaging, the first discharge port 412 and the second discharge port 422 are respectively movably connected with the first sealing plate 7 and the second sealing plate 8, the ton bag is placed on the weighing device, and when the weighing device shows that the bulk grain in the ton bag reaches the specified weight, the corresponding first sealing plate 7 and second sealing plate 8 are immediately closed.

The first sealing plate 7 and the second sealing plate 8 are controlled by the same driving component 9, which is used to control the opening and closing of the first discharge port 412 and the second discharge port 422 by the first sealing plate 7 and the second sealing plate 8. When the driving component 9 controls the first sealing plate 7 to close the first discharge port 412, the second sealing plate 8 opens the second discharge port 422. When the driving component 9 controls the second sealing plate 8 to close the second discharge port 422, the first sealing plate 7 opens the first discharge port 412. The driving component 9 includes a control rack 91, which is slidingly connected to the bag holder 6 in the horizontal direction. The first discharge pipe 41 and the second discharge pipe 42 are provided with a first through slot 413 and a second through slot 423 below the hinged positions of the first sealing plate 7 and the second sealing plate 8, respectively, for the two ends of the control rack 91 to pass through. The two ends of the control rack 91 can abut and drive the first sealing plate 7 and the second sealing plate 8 to rotate to close the first discharge port 412 and the second discharge port 422, respectively. The first discharge pipe 41 and the second discharge pipe 42 are respectively rotatably connected to the opposite shells of the control rack 91, and two gears 92 are engaged with the control rack 91. The crossbar 61 is connected with a transmission member 93, which can control the rotation of the gear 92. The tooth portion of the control rack 91 is provided on the bottom surface of the control rack 91. The transmission member 93 includes a driving end 931 slidingly provided in the bottom wall of the insertion slot 613 in the vertical direction and a transmission end 932 engaged with the gear 92 in the vertical direction away from the other side of the gear 92. The driving end 931 is located on the crossbar 61 and is located on the side away from the positioning block 571 of the unlocking block 572. The side of the driving end 931 away from the unlocking block 572 is inclined downward away from the unlocking block 572. The outer wall of the first discharge pipe 41 and the second discharge pipe 42 can be further provided with a guide block for sliding connection of the transmission end 932, so as to improve the stability of the transmission structure.

[0053] Taking the example that the baffle 51 needs to close the first channel 411 and open the second channel 421, in the initial state, the driving end 931 of the transmission member 93 in the first bagging unit 611 is located in the insertion slot 613, and the driving end 931 of the transmission member 93 in the second bagging unit 612 is lower than the bottom wall height of the insertion slot 613, at this time, one end of the driving rack passes through the second insertion slot 423 to support the second sealing plate 8 to close the second discharge port 422, and the other end of the driving rack does not contact the first sealing plate 7, so as to ensure that the first discharge port 412 is in an open state. When the fork enters the insertion slot 613 of the cross rod 61, the fork gradually presses downward on the driving end 931 to drive the transmission end 932 to move downward, the gear 92 engaged with the transmission end 932 rotates clockwise, thereby moving the driving rack towards the first discharge pipe 41, the driving rack passes through the first insertion slot 413 to abut below the rotating part of the first sealing plate 7, and the driving rack only needs to move a small distance to drive the first sealing plate 7 to rotate to quickly close the first discharge port 412, and at the same time, the second sealing plate 8 is separated to open the second discharge port 422, thereby limiting the bulk grain to continue to fall into the ton bag that has been filled, and further improving the accuracy of ton bag packaging; moreover, the driving rack will drive the gear 92 on the other side to rotate clockwise, thereby moving the transmission end 932 of the other transmission member 93 upward to drive the driving end 931 into the insertion slot 613. Then, the fork continues to advance to push the driving block 54, and the baffle 51 is rotated to close the first channel 411, during the rotation of the baffle 51, the first channel 411 can be used as a temporary storage bin to realize the rapid stopping of the bulk grain discharge and the reversing of the discharge.

[0054] The implementation principle of the ton bag self-unloading equipment in the embodiment of the application is as follows:

[0055] When bagging, the rear compartment of the agricultural vehicle is tilted up to directly pour the bulk grain into the lower receiving hopper 1, the bulk grain in the receiving hopper 1 is lifted by the lifting mechanism 2, first, the baffle 51 of the distributing mechanism 3 will close the second channel 421, the bulk grain discharged from the discharge pipe 22 of the lifting mechanism 2 enters the ton bag through the first channel 411, when a ton bag is full, the forks of the forklift directly insert into the handle of the ton bag through the slot 613, the forks will first close the first discharge port 412 and open the second discharge port 422 through the driving part 9, so that the bulk grain stops falling into the full ton bag, as the forks continue to advance, the driving block 54 will be unlocked and pushed to move, the driving block 54 rotates the baffle 51 to close the first channel 411 and open the second channel 421 through the connecting rod 55, the bulk grain enters the empty ton bag below through the second channel 421 from the second discharge port 422, and at this time the driving block 54 is locked by the positioning part 57 to limit the movement of the baffle 51. Finally, the forks can first retreat a distance to avoid contacting the empty ton bag handle, and then lift up to directly fork the ton bag away, without manual bagging, the whole grain loading process does not need to stop the lifting mechanism 2, saving time and effort, and improving the grain loading efficiency.

[0056] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
