DETAILED DESCRIPTION

[0028] In order to clearly understand the technical scheme of the present application, a biobased degradable sandbag sand barrier filling equipment provided by the present application will be described in detail below in combination with specific embodiments and drawings.

[0029] The terms used in the following examples are merely for the purpose of describing specific embodiments and are not intended to be limiting of the present application. As used in the specification and claims of this application, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “at least one” or “one or more” as used in the following embodiments refers to one, two or more than two.

[0030] Reference in the specification to “one embodiment” or “some embodiments” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. The appearances of the phrases “in one embodiment,” “in some embodiments,” “in other embodiments,” “in additional embodiments,” and the like in various places in the specification are not necessarily all referring to the same embodiment, although they can. The terms “comprises,” “comprising,” “including,” “including,” “having,” and their variants are meant to encompass the terms “consisting of” and “consisting essentially of” unless otherwise noted.

[0031] Embodiment 1 provides a biobased degradable sandbag sand barrier filling equipment, referring to Figure 1, the appearance show of the filling equipment of the biobased degradable sandbag sand barrier is shown, it can be seen from the figure that the filling equipment includes a base 1, the base 1 is a rigid bearing structure, and is the mounting reference of all other components. The ring-shaped belt conveyor is fixedly connected to one side of the base 1 through a bottom support 3 in a bolted manner, and the ring-shaped belt conveyor is arranged in a ring shape. The ring-shaped belt conveyor is in transmission connection with a first driving source (in this embodiment, the first driving source directly selects a servo motor), so that the chain belt 5 of the ring-shaped belt conveyor realizes intermittent operation. After each operation of the ring-shaped belt conveyor, the adjacent placing seat 2 is aligned with the shaping ring 8. The placing seat 2 is fixedly arranged on the surface of the chain belt 5 at equal intervals, and a single placing seat 2 is adapted to a single special sandbag. The material placing disc 7 is fixedly installed on the base 1 on one side of the ring-shaped belt conveyor, and the material placing disc 7 is in a disc-shaped structure. The shaping ring 8 is fixed to the upper surface of the material placing disc 7, and the central axis of the shaping ring 8 intersects the moving track of the special sandbag, so that the special sandbag can be accurately adsorbed after being pushed to the shaping ring 8. The special sandbag interacts with the shaping ring 8, so that the special sandbag is unfolded to form a cylindrical shape, facilitating subsequent filling of the biomass raw material. The pushing mechanism (for example, a cylinder or an electric push rod can be used) is fixed to the base 1 on the inner side of the ring-shaped belt conveyor through a lateral support 9 in a bolted manner, and the output end faces the shaping ring 8. The discharging mechanism is fixed to the side of the material placing disc 7 through a side support 14, the discharge port is aligned with the central area of the shaping ring 8, and the biomass raw material is smoothly dropped into the special sandbag. The discharging mechanism is in transmission connection with a second driving source (in this embodiment, the second driving source directly selects a stepping motor), so that the biomass raw material is discharged from the discharge port of the discharging mechanism and filled into the special sandbag in the shaping ring 8. When the ring-shaped belt conveyor completes intermittent operation once (at this time, the shaping ring 8 is aligned with the adjacent placing seat 2), the output end of the pushing mechanism is stretched out to push the special sandbag in the placing seat 2 to the adsorption area above the shaping ring 8. At this time, the special sandbag is collinear with the central axis of the shaping ring 8, so as to ensure alignment.

[0032] In particular, with reference to Figure 2, the overall structure of the ring belt conveyor is shown, and it can be seen from the figure that the ring belt conveyor comprises a bottom support 3, four sprockets 4 are rotatably connected with four corners of the bottom support 3 through bearing seats respectively, so that the sprockets 4 can rotate around their own axes. The chain belt 5 has a closed ring structure and is connected at the head and tail through chain links; the chain belt 5 is wound around the circumferential side of the four sprockets 4, and the chain links are in meshing transmission with the sprocket teeth of the sprockets 4; one of the sprockets 4 is in transmission connection with the first driving source, and the remaining sprockets 4 are driven sprockets 4 and are only passively rotated. The placing seat 2 is fixed on the chain links of the chain belt 5 by welding or the like and moves synchronously with the chain belt 5. The ring track 6 is fixedly installed on the bottom support 3 at the outer side edge of the chain belt 5 and forms a closed ring-shaped guide groove, and the ring track 6 is matched with the rollers of the placing seat 2. The movement track of the chain belt 5 and the placing seat 2 is jointly defined by the arrangement of the sprockets 4 and the ring track 6, so as to ensure the stability of the movement of the placing seat 2; and the driving force of the first driving source is matched, so as to ensure that the plurality of placing seats 2 can move along the closed track in an intermittent manner; the special sandbag on each placing seat 2 can fall into the shaping ring 8 in turn, and the closed ring design of the ring belt conveyor also saves space to a certain extent.

[0033] Specifically, referring to Figure 3 , the three-dimensional structure of the discharging mechanism is shown, and it can be seen from the figure that the discharging mechanism comprises a hopper 10, the hopper 10 is a component for initially receiving the material, and a filter screen 11 is installed inside the hopper 10, which is used for filtering impurities in the biomass material. The hopper 10 is integrally connected with a filter slope plate 12 on one side, and a vibration motor 17 is additionally installed on the hopper 10. Under the joint action of the vibration motor 17 and the filter screen 11, the impurities in the biomass material are blocked by the filter screen 11 and enter the filter slope plate 12 and are guided out by the filter slope plate 12, and the biomass material passes through the filter screen 11 and enters the groove 13 below. The bottom of the hopper 10 is in communication with the inlet end of the groove 13, and the groove 13 is a component for containing a screw rod 15, a helical blade 16 and conveying the biomass material. The groove 13 is supported by a side support 14 fixed on the material distributing disc 7. The screw rod 15 is arranged inside the groove 13, the helical blade 16 is installed on the screw rod 15, and one end of the screw rod 15 is in transmission connection with the second driving source. Under the driving of the second driving source, the helical blade 16 rotates in the groove 13 together with the screw rod 15; the screw rod 15 and the helical blade 16 cooperate with each other to push the biomass material to move along the length direction of the groove 13, so as to realize the conveying of the biomass material.

[0034] Specifically, referring to Figures 4-6 , wherein, Figure 4 , the assembly structure of the special sandbag, the placing seat 2 and the shaping ring 8 is shown, Figure 5 , the state diagram of the special sandbag when it is contracted is shown, Figure 6The special sandbag is shown in the state diagram after being expanded. As can be seen from the above diagram, the special sandbag comprises a woven bag 18, and support columns 19 made of acrylic material are fixed to the top left and right side edges of the woven bag 18 by means of an adhesive process; a plurality of thin iron wires 20 with a diameter of 0.5-1 mm are embedded in the outer surface of the woven bag 18, the thin iron wires 20 are embedded in the woven bag 18 fabric and are fixed by being wrapped by the woven structure, and are used to maintain the shape of the woven bag 18 after being expanded; the bottom of the woven bag 18 is integrally connected with a bottom support 21 made of HDPE / PP plastic material, and a first magnet 22 is arranged in the center of the bottom support 21 (the first magnet 22 is used for subsequent magnetic attraction cooperation with a second magnet 23). Arc grooves 24 are formed in the left and right side edges of the shaping ring 8, the arc grooves 24 are matched with the support columns 19 of the woven bag 18, and the arc grooves 24 provide an initial alignment guide and a contact structure for stress breakage of the support columns 19. When the bottom support 21 of the woven bag 18 is placed directly above the shaping ring 8, the two support columns 19 at the top of the woven bag 18 are correspondingly matched with the arc grooves 24 on the left and right sides of the shaping ring 8; at this time, the first magnet 22 in the center of the bottom support 21 and the second magnet 23 on the material placing disc 7 are driven to pass through the shaping ring 8 and are fixed on the surface of the material placing disc 7 by magnetic attraction force. During the downward movement of the bottom support 21, the support columns 19 first contact the arc grooves 24 (the edges of the arc grooves 24 limit the support columns 19), and then the acrylic support columns 19 are broken due to the combined action of the gravity of the bottom support 21 and the tension of the woven bag 18; at the moment when the support columns 19 contact the arc grooves 24, the woven bag 18 is forcibly expanded by using the constraint of the arc grooves 24 (the woven bag 18 is stretched from the natural state to the working state); the thin iron wires 20 outside the woven bag 18 continuously maintain the expanded state (avoiding the woven bag 18 from shrinking due to the breakage of the support columns 19, and ensuring the structural stability).

[0035] The working process of the embodiment 1 of the present application is as follows:

[0036] In the first step, the special sandbags (containing the support columns 19, the thin iron wires 20 and the bottom support 21 with the first magnet 22) are placed one by one on the placing seats 2 of the ring belt conveyor; the biomass raw materials are poured into the hopper 10 of the feeding mechanism, and the filter screen 11 and the vibration motor 17 (auxiliary filtering) in the hopper 10 are in a standby state.

[0037] In the second step, the first driving source (servo motor) drives the ring belt conveyor to operate: the chain belt 5 of the ring belt conveyor is intermittently moved along the closed loop track under the drive of the chain wheel 4 (guided by the ring track 6, to ensure the stable movement of the placing seat 2), and after each intermittent operation, the placing seat 2 is aligned with the shaping ring 8 on the material placing disc 7 (i.e., the position of the placing seat 2 is accurately matched with the position of the shaping ring 8).

[0038] Step 3: After the placement seat 2 is aligned with the shaping ring 8, the output end of the pushing mechanism (such as a pneumatic cylinder or an electric push rod) is extended to push the special sandbag in the placement seat 2 to the adsorption area above the shaping ring 8. At this time, the central axis of the special sandbag is collinear with the central axis of the shaping ring 8, ensuring accurate alignment for subsequent operations.

[0039] Step 4: The first magnet 22 of the special sandbag bottom support 21 and the second magnet 23 on the material swinging plate 7 generate a magnetic attraction force, driving the bottom support 21 to pass through the shaping ring 8 and be adsorbed and fixed on the surface of the material swinging plate 7. During the downward movement of the bottom support 21, the acrylic support column 19 at the top of the sandbag contacts the arc groove 24 on both sides of the shaping ring 8, which limits the support column 19. Under the combined action of the gravity of the bottom support 21 and the tension of the sandbag itself, the support column 19 breaks brittlely. At the same time, the constraint of the arc groove 24 forces the sandbag to be stretched from the natural shrinkage state (such as Figure 5 ) to the cylindrical working state (such as Figure 6 ). After the support column 19 breaks, the fine iron wire 20 (diameter 0.5-1mm) embedded in the outer layer of the sandbag continuously maintains the expanded state of the sandbag, preventing it from shrinking and providing a stable space for subsequent filling.

[0040] Step 5: The vibration motor 17 in the hopper 10 is started, and the filter screen 11 is used to filter the biomass raw materials. The impurities are blocked by the filter screen 11 and discharged through the impurity filtering slope plate 12. The qualified raw materials pass through the filter screen 11 into the lower groove 13. The screw 15 and spiral blade 16 in the groove 13 are driven to rotate by the second driving source, conveying the raw materials along the groove 13 to the discharge port. The discharge port is aligned with the center of the shaping ring 8, and the raw materials are accurately dropped into the expanded special sandbag, completing the filling. After the filling of a single sandbag is completed, the next special sandbag-filled placement seat 2 is moved to the shaping ring 8 by the continuous intermittent operation of the ring belt conveyor, and the above "pushing, expanding, and filling" process is repeated to realize continuous filling operation.

[0041] The present application solves the problem of how to fill a batch of biobased degradable sandbags. Through the closed-loop intermittent operation of the ring belt conveyor, the continuous conveying and station switching of the special sandbag are realized, improving the batch filling efficiency and saving space. The special sandbag cooperates with the shaping ring 8, and through magnetic attraction, support column 19 breaking, and fine iron wire 20 maintaining the shape, it realizes automatic expansion and fixation, reducing manual intervention. The discharging mechanism filters impurities through the filter screen 11 and vibration motor 17, and accurately discharges through the screw conveyor, ensuring the purity of the raw materials and the filling accuracy. The coordinated operation of various components realizes automatic continuous production, improving the overall filling stability and work efficiency.

[0042] In Example 2, when the specially designed sandbags fall and adhere to the material tray 7, if they are not promptly moved from their original landing point to other parts of the tray 7, they are prone to accumulating at the original landing point, thus affecting the normal falling and processing of subsequent sandbags. To solve this problem, this embodiment also designs an intermittent pushing mechanism. This intermittent pushing mechanism is connected to the material tray 7 and is used to push the specially designed sandbags away from their original landing point. Each rotation pushes the sandbag a certain distance until it falls from the receiving port 34 into the designated collection device. The specific structure of the intermittent pushing mechanism is as follows.

[0043] refer to Figures 7-8 ,in, Figure 7 The diagram shown is a first-person view of the assembly of the intermittent feeding mechanism. Figure 8 The diagram shows an assembly schematic from a second perspective of the intermittent feeding mechanism. As can be seen from the two diagrams above, the intermittent feeding mechanism includes an arc-rail pusher plate 25, with a pin 26 concentrically mounted at the center of the swaying plate 7. The arc-rail pusher plate 25 is concentrically fixed to one end of the pin 26 at the top of the swaying plate 7. A grooved wheel 27 is concentrically fixed to the other end of the pin 26 at the bottom of the swaying plate 7. The grooved wheel 27 and the arc-rail pusher plate 25 are coaxially linked; that is, when the grooved wheel 27 rotates, the arc-rail pusher plate 25 rotates synchronously at the same angle. Four claws 28 are evenly distributed circumferentially on the grooved wheel 27, each claw 28 having a groove at its end. The groove can accommodate the drive pin 31 of the drive wheel 30. A concave arc surface 29 is machined on the outer circumferential surface of the grooved wheel 27 between adjacent claws 28. The drive wheel 30 is rotatably connected to the swivel plate 7 via a revolute joint (such as a bearing), and the drive wheel 30 is concentrically fixed to the output shaft of the servo motor 33. The servo motor 33 is fixed on the swivel plate 7, providing rotational power to the drive wheel 30. A notch 32 is provided on one side of the outer rim of the drive wheel 30, and a drive pin 31 is fixedly connected to the notch 32. The claw 28 of the Geneva wheel 27 can slide over the notch 32 of the drive wheel 30, the concave arc surface 29 of the Geneva wheel 27 can slide over the outer rim of the drive wheel 30, and the flange of the drive pin 31 can slide over the groove of the claw 28. The Geneva wheel 27, the drive wheel 30, and the drive pin 31 together constitute a Geneva mechanism.

[0044] In combination with the above connection relationship, the working principle of the intermittent pushing mechanism is as follows: during each rotation of the driving wheel 30: first, the steering wheel 33 drives the driving wheel 30 to rotate, when the driving pin 31 enters the groove of the claw part 28 of the notch part 32 of the driving wheel 30, the flange of the driving pin 31 and the groove are matched by sliding to transmit the tangential force, which drives the notch part 32 of the driving wheel 30 to rotate, at this time, the claw part 28 of the notch part 32 slides in the notch part 32 of the driving wheel 30; because the notch part 32 of the driving wheel 30 and the arc rail pushing disc 25 are coaxially connected, when the notch part 32 of the driving wheel 30 rotates, the arc rail pushing disc 25 synchronously rotates by the same angle (at this time, each time the notch part 32 of the driving wheel 30 rotates 90°, the arc rail pushing disc 25 also rotates 90° correspondingly). Then, when the flange of the driving pin 31 is separated from the groove of the claw part 28 of the notch part 32, the outer rim of the driving wheel 30 is in contact with the concave surface 29 of the notch part 32, and the rotation of the notch part 32 is limited by sliding friction, so that the intermittent stopping is realized (to ensure that the arc rail pushing disc 25 is stably stopped and waits for the next pushing action). At the same time, when the driving wheel 30 is in the initial stationary state (i.e., before each rotation of the driving wheel 30), one of the arc-shaped tracks 47 on the arc rail pushing disc 25 is concentrically aligned with the shaping ring 8, so that the woven bag 18 can be accurately dropped into the arc-shaped track 47 when it falls, and the positioning of the woven bag 18 is completed, which provides an initial attitude guarantee for the subsequent pushing action.

[0045] In the embodiment 3, the intermittent pushing mechanism and the chain belt 5 need to rely on two independent driving sources (the chain belt 5 relies on the first driving source, and the intermittent pushing mechanism relies on the steering wheel 33). This arrangement of multiple driving sources not only increases the cost and energy consumption of the equipment, but also is more likely to cause the intermittent pushing mechanism and the placing seat 2 of the chain belt 5 to be unable to realize precise linkage due to the asynchronous action of the driving sources. To solve the above problems, the embodiment sets a new first driving source, which forms a transmission connection with the intermittent pushing mechanism and the chain belt 5 through the linkage belt 35, so as to replace the original first driving source (i.e., the servo motor in the embodiment 1), and the linkage of the intermittent pushing mechanism and the placing seat 2 of the chain belt 5 can be realized by only a single driving. The specific connection relationship of the new first driving source is as follows.

[0046] Reference Figure 9 As shown in FIG. 6, which is a schematic diagram of the installation structure of the linkage belt 35, it can be seen that the first driving source includes the linkage belt 35, one end of the linkage belt 35 is in transmission connection with the pin shaft 26, and the other end of the linkage belt 35 is in transmission connection with one of the sprockets 4. At the same time, it is limited that when the flange of the driving pin 31 enters the groove of the claw part 28 of the notch part 32, the linkage belt 35 links the chain belt 5 and the placing seat 2 to rotate; and when the flange of the driving pin 31 is separated from the groove of the claw part 28 of the notch part 32, the linkage belt 35 no longer links the chain belt 5 and the placing seat 2 to rotate, at this time, the shaping ring 8 is arranged opposite to the adjacent placing seat 2, and the shaping ring 8 is concentrically arranged with the adjacent arc-shaped track 47 of the arc rail pushing disc 25 below.

[0047] In combination with the above connection relationship, the benefits of the linkage belt 35 are: reducing the number of driving sources, reducing equipment cost and energy consumption; realizing precise linkage of the intermittent pushing mechanism and the chain belt 5 placing seat 2, and improving equipment operation stability and work efficiency. And the linkage belt 35 needs to be combined with the intermittent pushing mechanism and the ring belt machine, and through the transmission connection with the pin shaft 26 of the intermittent pushing mechanism and the sprocket 4 of the ring belt machine respectively, the above effects can be achieved, and it cannot be used separately.

[0048] In embodiment 4, the start of the pushing mechanism and the movement of the intermittent pushing mechanism are difficult to realize precise linkage, which easily leads to the action coordination disorder of the two, affecting the coordination and work efficiency of the equipment. To solve the above problems, the infrared induction device is designed in this embodiment to realize the linkage control of the pushing mechanism and the intermittent pushing mechanism. The specific structure of the infrared induction device is as follows.

[0049] Reference Figures 10-11 , wherein Figure 10 The figure shows the installation structure diagram of the infrared induction device, and Figure 11 The figure shows the use state diagram of the infrared induction device, from which it can be seen that the infrared induction device includes an infrared emitter 36, a vertical line y and a horizontal line x divide the driving wheel 30 into four areas A, B, C, and D, the gap part 32 is located in the A area of the driving wheel 30, and the infrared emitter 36 is located in the B area of the driving wheel 30; the steering wheel 33 output shaft below the driving wheel 30 is concentrically fixed with a turntable 38, and the infrared induction device is fixedly installed on the lower surface of the turntable 38; the base 1 is provided with an infrared sensor 37. When the linkage driving pin 31 is separated from the groove (the driving wheel 30 rotates along the a direction), the infrared emitter 36 in the B area of the driving wheel 30 rotates and is aligned with the infrared sensor 37, the infrared emitted by the infrared emitter 36 is received by the infrared sensor 37 and is returned to the controller, and the controller instructs the pushing mechanism to start.

[0050] In embodiment 5, the feeding mechanism relies on the original independent second driving source (i.e. the stepping motor in embodiment 1) for driving, and lacks linkage with the movement of the intermittent pushing mechanism, which easily leads to the asynchronization of the two actions, resulting in that after the special sandbag falls on the material placing disc 7 and completes the opening state, precise feeding cannot be realized, and the number of equipment driving sources is also increased. To solve the above problems, a new second driving source is designed in this embodiment to replace the original second driving source, so that the second driving source directly uses the driving force of the intermittent pushing mechanism to realize precise feeding after the special sandbag completes the opening, thereby realizing the linkage of the movement of the feeding mechanism and the intermittent pushing mechanism. The specific structure of the second driving source is as follows.

[0051] Reference Figures 12-13 , wherein Figure 12 The figure shows the assembly structure diagram of the new second driving source, and Figure 13The partial assembly structure schematic diagram of the new second driving source is shown, and it can be seen from the above two figures that the second driving source comprises teeth 39: a plurality of teeth 39 are distributed in a fan array form on the circumferential edge of the rotating disc 38, and the distribution area of the fan-shaped teeth 39 corresponds to the C and D fan-shaped areas of the driving wheel 30 (as shown in the above two figures), and the fan-shaped teeth 39 on the rotating disc 38 can be engaged and matched with the tooth disc 40. Figure 11 The tooth disc 40 and the first bevel gear 41 are concentrically sleeved on the top end of the stand 46 in sequence, and the bottom end of the stand 46 is rigidly fixed with the base 1. The second bevel gear 42 is concentrically fixed on the transmission shaft 43, the transmission shaft 43 is rotatably connected with the support 44, the support 44 is fixedly connected with the base 1, and the belt 45 is connected with the pulley of the transmission shaft 43 and the pulley of the screw rod 15 of the discharging mechanism at two ends respectively, so as to form a belt transmission and realize power transmission between the transmission shaft 43 and the screw rod 15. With the continuous rotation of the driving wheel 30 and the rotating disc 38 (in the a direction), when the infrared emitter 36 and the infrared sensor 37 are gradually dislocated, the fan-shaped teeth 39 will be engaged with the tooth disc 40.

[0052] The driving wheel 30 will experience three stages in one rotation: in the first stage, the indirect linkage arc rail push disc 25 completes single pushing of the corresponding special sandbag, and at the same time, the indirect linkage placing seat 2 reaches the opposite position of the shaping ring 8; in the second stage, the indirect linkage infrared emitter 36 rotates and is aligned with the infrared sensor 37, at this time, the pushing mechanism pushes the corresponding special sandbag to the upper side of the shaping ring 8; in the third stage, when the special sandbag under the shaping ring 8 completes the opening state, combined with the second driving source, the discharging mechanism completes the loading of the corresponding special sandbag. Through the combination of the first driving source, the infrared sensing device and the second driving source, the intermittent pushing mechanism is linked with the ring belt conveyor, the pushing mechanism and the discharging mechanism, so that the mechanisms work cooperatively.

[0053] The overall working process of the present application is as follows:

[0054] Initial preparation: place the special sandbags containing the support column 19, the thin iron wire 20 and the first magnet 22 bottom support 21 on the placing seat 2 of the ring belt conveyor one by one; pour the biomass raw material into the hopper 10 of the discharging mechanism, and ensure that the filter screen 11, the vibration motor 17 and each linkage component (intermittent pushing mechanism, infrared sensing device, etc.) are in a standby state.

[0055] Linkage conveying and station switching: the new first driving source simultaneously drives the sprocket 4 of the ring belt conveyor and the pin shaft 26 of the intermittent pushing mechanism through the linkage belt 35, so that the chain belt 5 of the ring belt conveyor moves intermittently along the closed loop track (guided by the ring track 6), and after each intermittent, one placing seat 2 is accurately aligned with the shaping ring 8 of the material swinging disc 7; at the same time, the Geneva mechanism composed of the slot wheel 27 of the intermittent pushing mechanism and the driving wheel 30 is linked, and the arc rail push disc 25 is synchronously intermittently rotated, preparing for material receiving and pushing.

[0056] Sandbag pushing and alignment: When the placing seat 2 is aligned with the shaping ring 8, the infrared sensing device triggers the pushing mechanism to start, and the output end pushes the special sandbag in the placing seat 2 to the adsorption area above the shaping ring 8, ensuring that the center axis of the sandbag is collinear with the shaping ring 8.

[0057] Sandbag expansion and fixation: The first magnet 22 of the special sandbag bottom support 21 is magnetically attracted to the second magnet 23 of the material placing disc 7, driving the bottom support 21 to pass through the shaping ring 8 and be adsorbed and fixed; when the bottom support 21 moves downward, the top support column 19 contacts the arc groove 24 of the shaping ring 8, which is brittle and breaks under the action of gravity and tension, and the arc groove 24 forces the sandbag to expand from the contracted state to a cylindrical shape, and the outer layer of fine iron wire 20 maintains the expanded state.

[0058] Raw material filtering and precise filling: The new second driving source drives the power linkage of the intermittent pushing mechanism: when the driving wheel 30 rotates to a specific stage, the gear teeth 39 of the rotating disc 38 engage with the toothed disc 40, which drives the screw 15 and the spiral blade 16 to rotate through bevel gears and belt transmission; the vibration motor 17 in the hopper 10 filters impurities (impurities are discharged through the filter slope plate 12), and the qualified raw materials are conveyed to the discharge port through the groove 13 and precisely fall into the expanded sandbag to complete the filling. After a single sandbag is filled, the arc rail pushing disc 25 of the intermittent pushing mechanism pushes it away from the original landing point to avoid accumulation; the ring belt conveyor continues to operate intermittently, driving the next placing seat 2 to the position, repeating the above process.

[0059] In the present application, the new first driving source serves as a single drive, which simultaneously drives the intermittent pushing mechanism and the ring belt conveyor through the linkage belt 35, reducing the number of driving sources to reduce cost and energy consumption, and realizing precise linkage of pushing and conveying; the intermittent pushing mechanism avoids sandbag accumulation, ensuring smooth process; the infrared sensing device ensures precise cooperation between the pushing mechanism and the intermittent pushing mechanism, improving coordination; the new second driving source uses the power of the intermittent pushing mechanism to reduce the number of driving sources and realize the linkage of feeding and pushing, ensuring precise feeding.

Claims

A filling device for bio-based biodegradable sandbag barriers, characterized in that: The system includes a base, a ring-shaped conveyor belt fixed to one side of the base, a ring-shaped conveyor belt connected to a first drive source for intermittent chain operation, and placement seats fixed at equal intervals on the surface of the chain belt for placing special sandbags. A material-laying tray is fixed to the base and located on one side of the ring-shaped conveyor belt. A shaping ring is fixed to the upper surface of the material-laying tray to unfold the special sandbags into a cylindrical shape; the axis of the shaping ring intersects the movement trajectory of the special sandbags. A pushing mechanism is fixed to the base, with its output end facing the shaping ring, for pushing the special sandbags in the placement seats to the adsorption area above the shaping ring. A feeding mechanism is fixed to the side of the material-laying tray, with its discharge port aligned with the center of the shaping ring and connected to a second drive source for discharging biomass raw materials and filling them into the special sandbags. The special sandbags include woven bags with support columns fixed to the top left and right edges of the woven bags. Multiple thin iron wires are embedded in the inner layer to maintain the shape of the woven bag after it is stretched. The bottom of the woven bag is integrally formed with the base, and the base has a first magnet built into its center. The left and right edges of the shaping ring are machined with arc grooves that match the support columns. A second magnet is provided on the material tray, which works with the first magnet to drive the base through the shaping ring and fix it to the surface of the material tray. When the base of the woven bag is placed directly above the shaping ring, the two support columns at the top of the woven bag correspond one-to-one with the arc grooves on the left and right sides of the shaping ring.
