A filling and transporting device for sandbag sand barriers

Abstract

This invention belongs to the field of sandbag filling, and particularly relates to a sandbag filling and transportation device, including a docking frame, a belt conveyor, a sand and gravel screening structure, a feeding structure, a bagging structure, and strip-shaped sandbags. In this invention, the sand and gravel screening structure can sequentially divide the sand between two adjacent baffles on the belt conveyor into multiple small portions and throw them onto the screening screen, thereby ensuring that the sand and gravel fully contact the screening screen for screening, improving the screening effect and increasing the amount of sand and gravel obtained after screening, which is convenient for subsequent bagging. After the throwing hopper throws the sand and gravel, the thrown sand and gravel will move along the arc surface after contacting the first concave arc surface and the second concave arc surface, thereby further spreading the thrown sand and gravel, further increasing the contact area between the sand and gravel and the screening screen, improving the screening efficiency and the amount of sand and gravel obtained after screening.

Description

Technical Field

[0001] This invention belongs to the field of sandbag filling, and particularly relates to a sandbag filling and transportation device. Background Technology

[0002] In wind and sand control and sand fixation projects, sand is filled into long sandbags and laid on the sandy surface to form strip-shaped sand barriers. These sand barriers can block the wind, thereby reducing wind speed and wind erosion. Before filling the long sandbags, the sand needs to be sieved to prevent sharp objects from tearing them. Existing sandbag filling equipment typically uses a shovel to scoop up the sand, then pours it onto a conveyor belt, which transports it to an inclined screen for screening. During screening, a large amount of sand is poured onto the screen and rolls down its inclined surface. However, a significant amount of sand is discharged before it even contacts the screen, resulting in insufficient sand being filled into the long sandbags. Furthermore, the filling equipment needs to continuously move forward to scoop up sand, and as the sieved sand is filled into the long sandbags, the sandbags are gradually released from the equipment. If insufficient sand is filled, the released sandbags may partially collapse, affecting their subsequent performance. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] This invention provides a sandbag filling and transportation device to address the problem that in existing sandbag filling equipment, a large amount of sand is discharged before it comes into contact with the screen during the sand screening process, resulting in insufficient sand being filled into the long sandbags. This leads to the partial collapse of the released sandbags and affects their subsequent use.

[0005] (II) Technical Content

The sand and gravel screening structure includes a screening box that is fixedly connected to the docking frame. The top and bottom of the screening box are open. A screening screen is fixedly connected to the inner wall of the screening box. The bottom opening of the screening box is fixedly connected to a feeding pipe that is fixedly connected to the docking frame.

[0009] A feeding structure corresponding to the feeding pipe is fixedly connected to the docking frame. The feeding structure includes a spiral conveying rod rotatably connected inside the feeding pipe.

[0010] A bagging structure corresponding to the feeding pipe is rotatably connected to the docking frame. The bagging structure includes two rotating rollers rotatably connected to the docking frame. The feeding pipe is located between the two rotating rollers, and a gap is left between the outer wall of the feeding pipe and the outer wall of the rotating rollers for the plastic bag to pass through. A strip-shaped sandbag is fitted at the outlet of the feeding pipe. The bag body of the strip-shaped sandbag passes through the gap and abuts against the rotating roller.

[0011] Furthermore, a tracked tractor is fixed to the side of the docking frame away from the sand and gravel screening structure;

[0012] The tracked tractor is positioned between two belt conveyors.

[0013] Furthermore, the belt conveyor is set at an angle, and baffles are fixed to the belt of the belt conveyor at equal intervals;

[0014] The input end of the belt conveyor is symmetrically fixed with gathering plates, and the side of the two gathering plates that are close to each other is provided with an inclined gathering surface.

[0015] A sand-collecting plate is fixed between the two gathering plates. The sand-collecting plate is set at an angle, with the lower end of the sand-collecting plate located below the gathering plates and the higher end of the sand-collecting plate located above the belt of the belt conveyor.

[0016] Furthermore, guide sand conveying plates are rotatably connected to the docking frame located below the output ends of the two belt conveyors via rotating shafts. A dual-axis servo motor is fixedly connected to the docking frame, with the dual-axis servo motor located between the two rotating shafts. The two output shafts of the dual-axis servo motor are respectively fixedly connected to the two rotating shafts.

[0017] Furthermore, the screening box comprises two parts: a drive chamber and a screening chamber.

[0018] The screening screen is fixed to the inner wall of the screening cavity at an incline. A stone discharge port is opened on the side of the screening box near the lower end of the screening screen. A limiting shaft is fixed to the inner wall of the drive cavity, and the limiting shaft is located above the screening screen.

[0019] The sand and gravel screening structure also includes multiple throwing hoppers. A swing arm is fixedly connected to the bottom of the throwing hopper. The end of the swing arm away from the throwing hopper is rotatably sleeved on the limiting shaft. Multiple sliding grooves corresponding to the swing arms are opened at the bottom of the inner wall of the drive cavity. A hollow toothed plate is slidably connected in each sliding groove.

[0020] A push rod is fixedly connected to one end of the hollow toothed plate near the swing arm. Multiple bushings corresponding to the push rod are fixedly connected to the side of the screening cavity near the push rod. The free end of the push rod passes through the corresponding bushing and extends into the screening cavity. A ball bearing is rolled and embedded at the end. A ball bearing is rolled and embedded in the inner wall of the bushing. The ball bearing rolls and contacts the outer wall of the push rod. The ball bearing rolls and contacts the corresponding swing arm intermittently. When the ball bearing rolls and contacts the corresponding swing arm, the swing arm tilts along the direction close to the ball bearing.

[0021] A limiting ring is fixedly sleeved on the push rod extending into the screening cavity, and a pushing spring is sleeved on the push rod. One end of the pushing spring abuts against the inner wall of the screening cavity, and the other end abuts against the limiting ring.

[0022] Furthermore, inclined support bars are fixed to the inner wall of the screening cavity, and a clamping plate is fixed to the top of the throwing hopper, with the clamping plate in intermittent contact with the inclined support bars;

[0023] A baffle cap is fixed to the top of the screening chamber, and an inclined baffle is fixed to the inner wall of the baffle cap. The clamping plate and the inclined baffle are in intermittent contact.

[0024] A first concave arc surface is provided on the inner wall of the screening cavity on the side away from the throwing hopper, and a second concave arc surface is provided on the inner wall of the baffle cap. The first concave arc surface and the second concave arc surface are connected.

[0025] Furthermore, the sand and gravel screening structure also includes a guide plate fixed to the screening box. The bottom of the guide plate covers the top of the drive cavity. A guide groove is provided on the guide plate. The bottom of the guide groove is inclined, and the lower end of the guide groove is located directly above the card plate.

[0026] Multiple dividing guide bars are fixed to the bottom of the guide trough. The dividing guide bars divide the guide trough into guide channels that correspond one-to-one with multiple throwing hoppers. The dividing guide bars are located between two corresponding throwing hoppers, and the two side walls of the dividing guide bars are respectively connected to the two corresponding throwing hoppers.

[0027] A triangular guide bar is fixed to the top of the separator guide bar, and a baffle is fixed to the lower end of the guide bar.

[0028] The free end of the guide sand conveying plate is located above the guide trough. When the free end of the guide sand conveying plate is located above one of the guide channels, the swing arm and the jacking ball corresponding to the guide channel are in rolling contact, and the corresponding drive half gear and hollow tooth plate are in a non-meshing state, while the drive half gear adjacent to the drive half gear meshes with the corresponding hollow tooth plate.

[0029] Furthermore, multiple sand-binding strips are fixed to the bottom of the inner cavity of the throwing hopper, which divide the inner cavity of the throwing hopper into multiple sand-binding grooves.

[0030] Furthermore, the feeding structure also includes a second rotary motor, which is fixedly connected to the docking frame, and the output shaft of the second rotary motor is fixedly connected to the corresponding screw conveyor rod.

[0031] Furthermore, the bottom of the two rotating rollers is rotatably connected to the docking frame, and the top of each of the two rotating rollers is fixedly connected to a cylindrical gear. The two cylindrical gears mesh with each other, and the top of each cylindrical gear is rotatably connected to the docking frame. The bagging structure also includes a third rotary motor fixedly connected to the docking frame, and the output shaft of the third rotary motor is fixedly connected to one of the cylindrical gears.

[0032] (III) Beneficial Effects

[0033] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0034] 1. In this invention, the sand and gravel screening structure can be set up to divide the sand and soil between two adjacent baffles on the belt conveyor into multiple small portions and throw them onto the screening net, so that the sand and soil can fully contact the screening net for screening, thereby improving the screening effect and increasing the amount of sand and soil obtained after screening, so as to facilitate subsequent bagging.

[0035] After the hopper throws out the sand, the thrown sand will move along the arc surface after contacting the first and second concave arc surfaces, thereby further spreading the thrown sand and increasing the contact area between the sand and the screening mesh, thus improving screening efficiency and the amount of sand obtained after screening.

[0036] 2. In this invention, when bagging, the opening of the strip-shaped sandbag is placed on the feeding pipe along the outlet of the feeding pipe, while the bag body of the strip-shaped sandbag passes through the gap between the feeding pipe and the rotating roller. The third rotary motor is turned on, and the output shaft of the third rotary motor drives the corresponding cylindrical gear and the corresponding rotating roller to rotate clockwise. Under the meshing action, another cylindrical gear and the rotating roller rotate counterclockwise. At this time, the rotation of the two rotating rollers will pull the strip-shaped sandbag, thereby gradually putting the strip-shaped sandbag on the feeding pipe.

[0037] During sand filling, the output shaft of the third rotary motor is controlled to rotate in the opposite direction, thereby controlling the roller to slowly release the strip-shaped sandbags so that sand can be filled into them. The workers can adjust the output shaft speed of the third rotary motor according to the moving speed of the tracked tractor, thereby controlling the release speed of the strip-shaped sandbags.

[0038] Third, in this invention, the baffle can block the sand on the belt, improve the sand transport efficiency of the belt, and prevent the sand from sliding down the inclined surface of the belt during the transport process, which would prevent the belt from being able to transport the sand from the input end of the belt conveyor to the output end of the belt conveyor.

[0039] Fourth, in this invention, the ball bearings can reduce the friction between the push rod and the bushing to facilitate the reciprocating motion of the push rod, and the actuating ball bearings can reduce the friction between the push rod and the swing arm.

[0040] Fifth, in this invention, the bottom of the guide plate covers the top of the drive cavity to prevent sand from falling into the drive cavity and affecting the meshing of the drive half gear and the hollow tooth plate.

[0041] VI. In this invention, the dividing guide is located between the two corresponding throwing hoppers, and the two side walls of the dividing guide are respectively connected to the two corresponding throwing hoppers to prevent sand from falling into the gap between the two throwing hoppers;

[0042] A triangular guide bar is fixed to the top of the dividing guide bar. When sand falls on the top of the guide bar, the sand can be guided to the corresponding guide channel through the inclined surface of the guide bar, avoiding accumulation on the guide bar. A baffle is fixed to the lower end of the guide bar to prevent some sand from falling into the gap between the two throwing hoppers along the lower end of the guide bar.

[0043] VII. In this invention, during the process of sand falling into the throwing hopper, the sand can be constrained by the sand-binding strips, causing it to fall into each sand-binding groove, thus preventing a large amount of sand from accumulating at the bottom of the inner cavity of the throwing hopper and spilling out from the bottom of the throwing hopper.

[0056] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] Example 1

[0058] like Figures 1-11 As shown, a sandbag and sand barrier filling and transportation device includes a docking frame 11, with a tracked tractor 12 fixedly connected to the side of the docking frame 11 away from the sand and gravel screening structure; belt conveyors 21 are fixedly connected to both sides of the docking frame 11, and the tracked tractor 12 is located between the two belt conveyors 21. The tracked tractor 12 can drive the docking frame 11 and the belt conveyors 21 fixed to both sides of the docking frame 11 to move together.

[0059] Furthermore, such as Figure 1As shown, the belt conveyor 21 is inclined, and baffles 211 are fixedly connected to the belt of the belt conveyor 21 at equal intervals. The baffles 211 can block the sand on the belt, improve the sand transport efficiency of the belt, and prevent the sand from sliding down the inclined surface of the belt during the transport process, which would prevent the belt from being able to transport the sand from the input end to the output end of the belt conveyor 21. The input end of the belt conveyor 21 is symmetrically fixed with gathering plates 22, and the side of the two gathering plates 22 that are close to each other is provided with an inclined gathering surface.

[0060] The bottoms of the two gathering plates 22 are in contact with the ground, and a sand-collecting plate 23 is fixed between the two gathering plates 22. The sand-collecting plate 23 is set at an angle, with the lower end of the sand-collecting plate 23 located below the gathering plates 22 and the higher end of the sand-collecting plate 23 located above the belt of the belt conveyor 21. The gathering plates 22 can gather the sand to the sand-collecting plate 23. When the bottoms of the two gathering plates 22 are in contact with the ground, the lower end of the sand-collecting plate 23 will pierce into the sand and shovel the sand onto the belt of the belt conveyor 21 as the tracked tractor 12 moves.

[0061] Both belt conveyors 21 have sand and gravel screening structures installed below their output ends, such as... Figure 2 and Figure 5 As shown, the sand and gravel screening structure includes a screening box 31 fixedly connected to the docking frame 11. The top and bottom of the screening box 31 are open. A screening screen 32 is fixedly connected to the inner wall of the screening box 31. The bottom opening of the screening box 31 is fixedly connected to a feeding pipe 51 fixedly connected to the docking frame 11. The belt conveyor 21 transports sand and soil to the screening box 31. The sand and soil can be screened through the screening screen 32 to remove stones from the sand and soil.

[0062] Specifically: such as Figure 2 and Figure 3 As shown, guide sand conveying plates 132 are rotatably connected to the docking frame 11 located below the output ends of the two belt conveyors 21 via rotating shafts 131. A dual-axis servo motor 13 is fixedly connected to the docking frame 11. The dual-axis servo motor 13 is located between the two rotating shafts 131. The two output shafts of the dual-axis servo motor 13 are fixedly connected to the two rotating shafts 131 respectively. The dual-axis servo motor 13 can simultaneously drive the corresponding guide sand conveying plates 132 to reciprocate through the two rotating shafts 131.

[0063] like Figures 4-10 As shown, the screening box 31 includes two parts: a driving cavity 311 and a screening cavity 312.

[0064] The screening screen 32 is fixed to the inner wall of the screening cavity 312 at an incline. The screening box 31 has a stone discharge port 3101 on the side near the lower end of the screening screen 32. When sand and gravel fall on the screening screen 32, they will roll down along the bottom end of the screening screen 32. The sand will fall through the mesh of the screening screen 32, while the stones will be discharged from the stone discharge port 3101.

[0065] A limiting shaft 33 is fixedly connected to the inner wall of the drive cavity 311, and the limiting shaft 33 is located above the screening screen 32;

[0066] The sand and gravel screening structure also includes multiple throwing hoppers 34. A swing arm 341 is fixedly connected to the bottom of the throwing hopper 34. The end of the swing arm 341 away from the throwing hopper 34 is rotatably sleeved on the limiting shaft 33. Multiple sliding grooves 3102 corresponding to the swing arms 341 are opened at the bottom of the inner wall of the drive cavity 311. A hollow toothed plate 41 is slidably connected in each sliding groove 3102. A main shaft 42 is rotatably connected to the inner wall of the drive cavity 311. Multiple drive half gears 43 corresponding to the hollow toothed plates 41 are fixedly sleeved on the main shaft 42. The drive half gears 43 mesh with the corresponding hollow toothed plates 41. A first rotary motor 44 is fixedly connected to the screening box 31. The output shaft of the first rotary motor 44 is fixedly connected to the main shaft 42.

[0067] A push rod 411 is fixedly connected to one end of the hollow toothed plate 41 near the swing arm 341. A plurality of bushings 45 corresponding to the push rod 411 are fixedly connected to the side of the screening cavity 312 near the push rod 411. The free end of the push rod 411 passes through the corresponding bushing 45 and extends into the screening cavity 312, and the end is rolled with a push ball 451. The inner wall of the bushing 45 is rolled with a ball. The ball rolls in contact with the outer wall of the push rod 411. The ball can reduce the friction between the push rod 411 and the bushing 45 so that the push rod 411 can reciprocate. The push ball 451 rolls in contact with the corresponding swing arm 341 intermittently. When the push ball 451 rolls in contact with the corresponding swing arm 341, the swing arm 341 tilts along the direction close to the ball. The push ball 451 reduces the friction between the swing arm 341 and the ball.

[0068] A limiting ring 46 is fixedly sleeved on the push rod 411 extending into the screening cavity 312. A pushing spring 47 is sleeved on the push rod 411. One end of the pushing spring 47 abuts against the inner wall of the screening cavity 312, and the other end abuts against the limiting ring 46.

[0069] Furthermore, an inclined support bar 313 is fixedly connected to the inner wall of the screening cavity 312, and a clamping plate 342 is fixedly connected to the top of the throwing hopper 34. The clamping plate 342 is in intermittent contact with the inclined support bar 313.

[0070] A baffle 35 is fixedly connected to the top of the screening cavity 312, and an inclined baffle 314 is fixedly connected to the inner wall of the baffle 35. The clamping plate 342 is in intermittent contact with the inclined baffle 314.

[0071] Furthermore, such as Figure 9 and Figure 10 As shown, the sand and gravel screening structure also includes a guide plate 36 fixedly connected to the screening box 31. The bottom of the guide plate 36 covers the top of the drive cavity 311 to prevent sand from falling into the drive cavity 311 and affecting the meshing of the drive half gear 43 and the hollow tooth plate 41. A guide groove 361 is provided on the guide plate 36. The bottom of the guide groove 361 is inclined, and the lower end of the guide groove 361 is located directly above the clamping plate 342.

[0072] Multiple dividing guide strips 362 are fixedly connected to the bottom of the guide trough 361. The dividing guide strips 362 can divide the guide trough 361 into guide channels 3601 corresponding to multiple throwing hoppers 34. The dividing guide strips 362 are located between two corresponding throwing hoppers 34, and the two side walls of the dividing guide strips 362 are respectively connected to the two corresponding throwing hoppers 34 to prevent sand from falling into the gap between the two throwing hoppers 34.

[0073] A triangular guide bar 363 is fixed to the top of the separator guide bar 362. When sand falls on the top of the guide bar 363, the sand can be guided to the corresponding guide channel 3601 through the inclined surface of the guide bar 363, so as to avoid accumulating on the guide bar 363. A baffle 364 is fixed to the lower end of the guide bar 363 to prevent some sand from falling into the gap between the two throwing hoppers 34 along the lower end of the guide bar 363.

[0074] The free end of the guide sand conveying plate 132 is located above the guide trough 361. When the free end of the guide sand conveying plate 132 is located above one of the guide channels 3601, the swing arm 341 and the jacking ball 451 corresponding to the guide channel 3601 are in rolling contact, and the corresponding drive half gear 43 and hollow tooth plate 41 are in a non-meshing state, so that the sand can fall into the throwing hopper 34 along the guide channel 3601. The drive half gear 43 adjacent to the drive half gear 43 meshes with the corresponding hollow tooth plate 41. Specifically, as the belt conveyor 21 works, the sand located between two adjacent baffles 211 is transported to the guide sand conveying plate 132, and under the action of the guide sand conveying plate 132, the sand is transported to the designated position. In a guide channel 3601 below, sand falling into the guide channel 3601 will fall along the inclined surface onto the corresponding clamping plate 342, and then into the corresponding throwing hopper 34. The operator can install a vibrating pump on the guide plate 36 and the screening screen 32 to increase the flow rate of the sand. Furthermore, multiple sand-binding strips 343 are fixed to the bottom of the inner cavity of the throwing hopper 34. The sand-binding strips 343 divide the inner cavity of the throwing hopper 34 into multiple sand-binding grooves 3401. During the process of the sand falling into the throwing hopper 34, the sand-binding strips 343 can constrain the sand and make it fall into each sand-binding groove 3401, preventing the sand from accumulating in large quantities at the bottom of the inner cavity of the throwing hopper 34 and spilling out from the bottom of the throwing hopper 34.

[0075] Along the swing direction of the guide sand conveyor plate 132, when the guide sand conveyor plate 132 moves above the next guide channel 3601, the drive half gear 43 and the hollow toothed plate 41 corresponding to the previous guide channel 3601 begin to mesh. The first rotary motor 44 drives the drive half gear 43 to rotate clockwise through the main shaft 42. Under the meshing action, the corresponding hollow toothed plate 41 will slide in the chute 3102 in a direction away from the throwing hopper 34, while driving the corresponding push... As the push rod 411 moves in the same direction, it gradually retracts into the drive cavity 311. During the retraction process, the limiting ring 46 applies a pushing force to the push spring 47, thereby compressing the push spring 47. Simultaneously, the corresponding throwing hopper 34 rotates counterclockwise a certain distance around the limiting shaft 33 under its own gravity. As the push rod 411 retracts, the clamping plate 342 on the throwing hopper 34 contacts the inclined support bar 313. At this time, the inclined support bar 313 prevents the throwing hopper 34 from continuing to rotate. As push rod 411 continues to retract, the actuating ball 451 will stop contacting the swing arm 341. When the drive half gear 43 stops meshing with the hollow toothed plate 41, the compressed push spring 47 will stretch and reset. During the reset, it will push push rod 411 out and reset through limit ring 46. At this time, push rod 411 will push swing arm 341 through actuating ball 451. Under the action of swing arm 341, it will drive hopper 34 to rotate clockwise. After push rod 411 resets... At this time, the throwing hopper 34 will continue to rotate a certain distance under the action of inertia. During the rotation, it will gradually approach the inclined baffle 314. When the clamping plate 342 contacts the inclined baffle 314, the inclined baffle 314 will prevent the throwing hopper 34 from continuing to rotate. At the same time, the sand in the throwing hopper 34 will be thrown out under the action of inertia. Under its own gravity, the throwing hopper 34 will rotate counterclockwise around the limiting shaft 33 as the rotation center to reset until the swing arm 341 contacts the jacking ball 451 again, thus completing the reset.

[0076] The process of throwing sand and soil from the remaining hoppers 34 is the same as described above, and will not be repeated here.

[0077] Compared to the existing method, which involves directly conveying sand to the screen via a conveyor, most of the sand is discharged before it even comes into contact with the screen, resulting in poor screening effect and insufficient amount of sand after screening, which affects subsequent bagging.

[0078] The sand and gravel screening structure can divide the sand between two adjacent baffles 211 on the belt conveyor 21 into multiple small portions and throw them onto the screening screen 32, so that the sand and gravel can fully contact the screening screen 32 for screening, thereby improving the screening effect and increasing the amount of sand and gravel obtained after screening, so as to facilitate subsequent bagging.

[0079] The baffle 35 prevents the hopper 34 from throwing sand out of the screening box 31.

[0080] Among them, workers can install shock-absorbing pads on the diagonal brace 313 and diagonal stop 314 to reduce the wear caused by frequent collisions between the card plate 342 and the diagonal brace 313 and diagonal stop 314;

[0081] Furthermore, such as Figure 4 and Figure 5 As shown, a first concave arc surface 315 is provided on the inner wall of the screening cavity 312 on the side away from the throwing hopper 34, such as... Figure 5 As shown, a second concave arc surface 351 is provided on the inner wall of the baffle 35, and the first concave arc surface 315 is connected to the second concave arc surface 351. After the throwing hopper 34 throws out the sand, the thrown sand will move along the arc surface after contacting the first concave arc surface 315 and the second concave arc surface 351, thereby further spreading the thrown sand, further increasing the contact area between the sand and the screening mesh 32, improving the screening efficiency and the amount of sand obtained after screening.

[0082] like Figure 2 and 11 As shown, a feeding structure corresponding to the feeding pipe 51 is fixedly connected to the docking frame 11. The feeding structure includes a spiral conveying rod 52 that is rotatably connected inside the feeding pipe 51.

[0083] The feeding structure also includes a second rotary motor 53, which is fixedly connected to the docking frame 11, and the output shaft of the second rotary motor 53 is fixedly connected to the corresponding screw conveyor 52.

[0084] A bagging structure corresponding to the feeding pipe 51 is rotatably connected to the docking frame 11. The bagging structure includes two rotating rollers 61 rotatably connected to the docking frame 11. The feeding pipe 51 is located between the two rotating rollers 61, and a gap is left between the outer wall of the feeding pipe 51 and the outer wall of the rotating rollers 61 for the plastic bag to pass through. Specifically, the bottom of the two rotating rollers 61 is rotatably connected to the docking frame 11, and the top of each of the two rotating rollers 61 is fixedly connected to a cylindrical gear 62. The two cylindrical gears 62 mesh with each other, and the top of each of the two cylindrical gears 62 is rotatably connected to the docking frame 11. The bagging structure also includes a third rotary motor 63 fixedly connected to the docking frame 11. The output shaft of the third rotary motor 63 is fixedly connected to one of the cylindrical gears 62.

[0085] A strip-shaped sandbag 71 is fitted at the outlet of the feeding pipe 51. The bag body of the strip-shaped sandbag 71 passes through the gap and abuts against the rotating roller 61. Specifically, when bagging, the opening of the strip-shaped sandbag 71 is fitted onto the feeding pipe 51 along the outlet of the feeding pipe 51, while the bag body of the strip-shaped sandbag 71 passes through the gap between the feeding pipe 51 and the rotating roller 61. The third rotary motor 63 is turned on, and the output shaft of the third rotary motor 63 drives the corresponding cylindrical gear 62 and the corresponding rotating roller 61 to rotate clockwise. Under the meshing action, another cylindrical gear 62 and the rotating roller 61 rotate counterclockwise. At this time, the rotation of the two rotating rollers 61 will pull the strip-shaped sandbag 71, thereby gradually fitting the strip-shaped sandbag 71 onto the feeding pipe 51.

[0086] During sand filling, the sand sieved by the screening screen 32 falls into the feeding pipe 51 through the opening at the bottom of the screening box 31. The second rotary motor 53 drives the screw conveyor 52 to rotate, and the screw conveyor 52 gradually conveys the sand into the strip-shaped sand filling bag 71. At the same time, the output shaft of the third rotary motor 63 is controlled to rotate in the opposite direction, thereby controlling the roller 61 to slowly release the strip-shaped sand filling bag 71 so that sand can be filled into the strip-shaped sand filling bag 71. The operator can adjust the output shaft speed of the third rotary motor 63 according to the moving speed of the tracked tractor 12, thereby controlling the release speed of the strip-shaped sand filling bag 71.

[0087] In summary, the workflow of this invention is as follows:

[0088] Before filling the sand, the opening of the strip-shaped sandbag 71 is first placed on the feed pipe 51 along the outlet of the feed pipe 51. At the same time, the bag body of the strip-shaped sandbag 71 passes through the gap between the feed pipe 51 and the rotating roller 61. The third rotary motor 63 is turned on. The output shaft of the third rotary motor 63 drives the corresponding cylindrical gear 62 and the corresponding rotating roller 61 to rotate clockwise. Under the meshing action, the other cylindrical gear 62 and the rotating roller 61 rotate counterclockwise. At this time, the rotation of the two rotating rollers 61 will pull the strip-shaped sandbag 71, thereby gradually putting the strip-shaped sandbag 71 on the feed pipe 51.

[0089] After the strip-shaped sandbags 71 are installed, the tracked tractor 12 drives the docking frame 11 and the belt conveyors 21 fixed to both sides of the docking frame 11 to move forward together. The lower end of the sand-collecting plate 23 will pierce into the sand and, as the tracked tractor 12 moves, shovel the sand onto the belt of the belt conveyor 21. As the belt conveyor 21 works, the sand between two adjacent baffles 211 will be transported to the guide sand-conveying plate 132. Under the action of the guide sand-conveying plate 132, the sand is transported to a material guide channel 3601 located below it. The sand falling into the material guide channel 3601 will fall along the inclined surface onto the corresponding clamping plate 342, thereby... The material falls into the corresponding throwing hopper 34 and moves along the swing direction of the guide sand conveying plate 132. When the guide sand conveying plate 132 moves above the next guiding channel 3601, the drive half gear 43 and the hollow tooth plate 41 corresponding to the previous guiding channel 3601 begin to mesh. The first rotary motor 44 drives the drive half gear 43 to rotate clockwise through the main shaft 42. Under the meshing action, the corresponding hollow tooth plate 41 slides in the slide groove 3102 in a direction away from the throwing hopper 34, and at the same time drives the corresponding push rod 411 to move in the same direction, gradually retracting it into the drive inner cavity 311. During the retraction process, the limit ring 46 applies a pressure to the push spring 47. The pushing force compresses the push spring 47, and the corresponding throwing hopper 34 rotates counterclockwise a certain distance around the limiting shaft 33 under its own weight. As the push rod 411 retracts, the clamping plate 342 on the throwing hopper 34 contacts the inclined support bar 313. At this time, the inclined support bar 313 will prevent the throwing hopper 34 from continuing to rotate. As the push rod 411 continues to retract, the actuating ball 451 will stop contacting the swing arm 341. When the drive half gear 43 stops meshing with the hollow tooth plate 41, the push spring 47, which is in a compressed state, will stretch and reset. During the reset, it will push the push rod 411 to extend and reset through the limiting ring 46. 411 will push the swing arm 341 through the actuating ball 451. Under the action of the swing arm 341, the throwing hopper 34 will rotate clockwise. When the push rod 411 is reset, the throwing hopper 34 will continue to rotate a certain distance under the action of inertia. During the rotation, it will gradually approach the inclined baffle 314. When the clamping plate 342 contacts the inclined baffle 314, the inclined baffle 314 will prevent the throwing hopper 34 from continuing to rotate. At the same time, the sand in the throwing hopper 34 will be thrown out under the action of inertia. Under its own gravity, the throwing hopper 34 will rotate counterclockwise around the limiting shaft 33 as the rotation center to reset until the swing arm 341 contacts the actuating ball 451 again, thus completing the reset.

[0090] After being thrown out, the sand will move along the arc surface after contacting the first concave arc surface 315 and the second concave arc surface 351, thereby further spreading the thrown sand. After the thrown sand falls on the screening screen 32, it will roll down along the bottom end of the screening screen 32. The sand will fall into the feeding pipe 51 through the mesh of the screening screen 32, while the stones will be discharged from the stone discharge port 3101.

[0091] The screened sand falls into the feeding pipe 51. The second rotary motor 53 drives the screw conveyor 52 to rotate, and the screw conveyor 52 gradually conveys the sand into the strip-shaped sandbag 71. At the same time, the output shaft of the third rotary motor 63 is controlled to rotate in the opposite direction, thereby controlling the roller 61 to slowly release the strip-shaped sandbag 71 so that sand can be filled into the strip-shaped sandbag 71. The operator can adjust the release speed of the strip-shaped sandbag 71 by adjusting the output shaft speed of the third rotary motor 63.

[0092] However, as is well known to those skilled in the art, the working principles and wiring methods of the tracked tractor 12, belt conveyor 21, dual-axis servo motor 13, first rotary motor 44, second rotary motor 53 and third rotary motor 63 are commonplace and belong to conventional means or common knowledge.
