Description

Technical Field

[0001] This invention relates to the field of sand barrier laying technology. Specifically, it relates to a clay conveying device and a sand barrier laying mechanism. Background Technology

[0002] Sand barriers, also known as mechanical sand barriers or wind barriers, are obstacles made of materials such as firewood, straw, clay, branches, slats, and pebbles on the sand surface. They are effective engineering measures for reducing wind speed and fixing the sand surface. Clay sand barriers consist of a thin layer of clay laid on top of sand. Since sand is easily blown by the wind, the clay layer covers it, making it less susceptible to movement. However, due to the stickiness of clay, it is easy for cavities to form inside the conveyor during transport, preventing the clay from being transported to the outside in time. This results in uneven laying of the clay sand barrier over a long period. Currently, rod-shaped structures are commonly used to compact the interior, but this structure is prone to internal wear and is also very troublesome to maintain and protect. There is a need for a clay conveying equipment and sand barrier laying mechanism that can automatically detect delays in sand barrier transport without affecting the transport process, and can promptly clear any cavities formed inside the clay layer to facilitate the delivery of subsequent clay to the conveyor shaft. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to provide a clay conveying device and a sand barrier laying mechanism that can adjust the angle of the dredging block and stop for a period of time. The first adjustment can cause the dredging block to spray gas over a large area, so that the clay at the adjustment position is dredged over a large area. Since the dredging block stops for a period of time, a small area of ​​dredging is carried out in the middle of the clay during this time.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0005] The device includes a frame, a conveying mechanism located in the middle of the frame, the conveying mechanism comprising a conveying shaft, a conveying plate, and a detection tube. The conveying shaft is rotatably mounted in the middle of the frame, the detection tube is located inside the conveying shaft, one end of the detection tube is connected to a squeezing tube, one side of the squeezing tube contacts a squeezing frame, and one side of the detection tube is equipped with a control mechanism, the control mechanism comprising a floating valve, a control valve, and a control wheel. The floating valve is slidably mounted on one side of the detection tube. An air supply pipe is located on the edge of the frame, one end of the air supply pipe is slidably equipped with a pressure valve, a unclog block is rotatably mounted on the edge of the frame, a release lever is rotatably mounted on one side of the unclog block, a driving block is located on the edge of the unclog block, a transverse block is slidably mounted on one side of the pressure valve, and a control bar is slidably mounted on one side of the control wheel.

[0006] The technical solution of the present invention achieves the following beneficial technical effects:

[0007] The angle of the unblocking block can be adjusted and paused for a period of time. The first adjustment causes the unblocking block to spray gas over a large area, thus unblocking the clay in the adjusted area. Since the unblocking block pauses for a period of time, it unblocks a small area in the middle of the clay during this time, and continues to unblock, creating an impact on a point. Through the connection between the extrusion pipe and the detection pipe, the liquid level can be raised when the conveyor plate does not feed, causing the floating valve to change position and controlling the air supply pipe to reach the inside of the frame. The pressure of the gas causes the pressure valve to move up and down to control the angle of the unblocking block. At the same time, it can make the unblocking block spray gas in an orderly manner to achieve contact with the clay. Attached Figure Description

[0016] This embodiment provides a clay conveying device, as shown in the attached instruction manual. Figure 1 As shown, the instruction manual is attached. Figure 1This is a traditional sectional view. Because the left side of this design is a long, tubular section, a section is cut off; therefore, the instruction manual includes... Figure 1 The left-side tubular assembly is displayed openly, but in reality, since the material continuously flows to the edge of the left-side frame 1, it is sealed. Therefore, the instruction manual includes... Figure 2 The instruction manual was used. Figure 1 The three-dimensional version of this solution has two core mechanisms: the first is the conveying shaft 2, and the second is the unblocking block 12. In order to solve the problem that the clay inside the frame 1 forms small cavities, causing the clay to accumulate inside the frame 1 and not be unloaded in time, this solution needs to set up a detection mechanism. The conveying shaft 2 in this solution is the detection mechanism. The detection in this solution is based on the amount of clay filled on the conveying plate 3.

[0017] As per the instruction manual Figure 3 As shown in this design, the conveyor shaft 2 still has four openings, each equipped with a conveyor plate 3. A supporting compression frame 6 is located on one side of each conveyor plate 3. When the conveyor plate 3 is not filled with sand, as shown in the lower two conveyor plates 3 diagram, the compression frame 6 allows the conveyor plate 3 to rotate against the wall of the frame 1. The compression frame 6 slides on the inner frame 31, which is integrally mounted on the conveyor shaft 2 and rotates with it. Since the upper part of the frame 1 stores clay, under normal conditions, the clay will fall into the upper right conveyor plate 3. As the conveyor shaft 2 rotates, the clay is orderly released to the left side. This is the normal conveying state. At this time, at least one of the four conveyor plates 3 will contain clay (two plates may also be present, as shown in the instruction manual). Figure 4 Two unloading processes occurred, with the unloading completed on the upper left side as the conveyor shaft 2 rotated 45 degrees. Only one conveyor plate 3 would have clay on it.

[0018] If clay forms a cavity inside the frame 1, the two upper conveyor plates 3 will not be able to convey clay, meaning there will be no clay. A compression spring 32 is installed on one side of the extrusion frame 6. This spring ensures that the lower conveyor plate 3 contacts the inner wall of the frame 1, resulting in all four conveyor plates 3 being compressed. The criterion for this design is that if none of the four conveyor plates 3 have clay, it indicates a hollow area inside the upper frame 1 or a lack of material feeding. As mentioned above, normally one or two conveyor plates contain clay. The extrusion frame 6 has a cylinder near the extrusion tube 5, with a circular tube fitted onto the cylinder. This is as per the instruction manual. Figure 4As shown in the diagram, the two lower conveyor plates 3 (in this design, one conveyor is limited to four conveyor plates 3, with adjacent plates at a 90-degree angle, and their positions are also set on a circular trajectory) will cause the edge of the extrusion frame 6 to contact the extrusion tube 5. The edge of the extrusion tube 5 is a rigid annular structure, which is fixedly mounted on the detection tube 4. In this design, the extrusion rod and the detection tube 4 are connected. The extrusion tube 5 is made of a memory soft material, while the outer side is supported by a rigid material, allowing it to reset after extrusion. The extrusion tube 5 is filled with liquid, and the detection tube 4 is also filled with liquid. At the same time, the liquid level in the detection tube 4 is higher than the top of the extrusion tube 5. Therefore, when all four conveyor plates 3 are free of clay, meaning all four have extruded the extrusion tube 5, the liquid inside the extrusion tube 5 will reach one end of the detection tube 4, as shown in the attached instruction manual. Figure 1 and 2 As shown, this causes the liquid level at one end of the detection tube 4 to rise, which is the judgment mechanism of this scheme.

[0019] To facilitate material feeding and discharging from the conveyor shaft 2 in this design, an extrusion frame 6 is installed on one side of the conveyor plate 3 to facilitate material discharge from the conveyor plate 3, as per the attached instruction manual. Figure 4 On the left side, under the action of the compression spring 32, the conveyor plate 3 is pushed outward. With the inner frame 31 as the center, the extrusion tube 5 is located on one side of the inner frame 31, while the guide block 33 of this design is located on the other side. The guide block 33 is also integrally set on the detection tube 4. One side of the guide block 33 is a slope, which allows the extrusion frame 6 located in the upper right corner to contact the guide block 33. Under the action of the guide block 33, the extrusion frame 6 is brought closer to the center, as shown in the attached instruction manual. Figure 4 As shown, the upper right conveyor plate 3 is depressed under the action of the extrusion frame 6 to facilitate the entry of materials. The guide block 33 and the edge of the extrusion frame 6 are misaligned and have a contact width. Therefore, the guide block 33 can make the extrusion frame 6 move towards the center of the conveyor shaft 2 when it reaches the upper right. One end of the extrusion frame 6 is connected to the conveyor plate 3 (it can be a fixed connection or an adhesive connection).

[0020] As per the instruction manual Figure 2 As shown, a floating valve 7 is slidably installed at one end of the detection tube 4. The bottom of the floating valve 7 is hollow, which can provide buoyancy. As shown above, the four conveying plates 3 are not filled, so all four squeeze the squeezing tube 5. The liquid discharged from the squeezing tube 5 naturally causes the liquid level to rise, that is, the floating valve 7 moves upward.

[0021] As per the instruction manual Figure 5 As shown, a control wheel 9 is engaged above the conveyor shaft 2. The control wheel 9 is rotatably mounted on one side of the frame 1. Therefore, when the conveyor shaft 2 rotates, the control wheel 9 also rotates, as shown in the attached instruction manual. Figure 4 In this design, the conveyor shaft 2 rotates counterclockwise. (See attached instruction manual.) Figure 5The conveyor shaft 2 rotates clockwise, while the control wheel 9 rotates counterclockwise. Due to the different viewing angles, the transmission direction between the two is restricted (if the transmission direction is not correct, simply mirror the corresponding control wheel 9 to achieve the desired result). One side of the floating valve 7 is cylindrical, which rests on the control groove 25. The control groove 25 is a recessed groove with a block in the middle. One side of this block is shown in the attached instruction manual. Figure 5 The shape shown is that of an arrow. At this point, the circular block is on the outer slope of the arrow (the outer slope here refers to the slope farther from the center of control wheel 9; since the arrow has two slopes, the inner slope is the slope closer to the center of control wheel 9). Therefore, under the action of the slope, the circular block moves downwards. The downward movement of the circular block indicates that the floating valve 7 in this design has not risen. If the floating valve 7 were to rise, it would contact the inner slope of the arrow, forcing the circular block to move upwards under the action of the inner slope. This means that the floating valve 7 moves upwards under the action of control wheel 9, and the upward movement is relatively large, as shown in the attached instruction manual. Figure 1 and 2 As shown, when the floating valve 7 moves upward, it will cause the control valve 8 to move upward as well. This is because the sliding distance of the floating valve 7 on the control valve 8 is less than the distance that the floating valve 7 is driven upward by the control wheel 9 after it floats. This causes the control valve 8 to also move upward a certain distance (a smaller distance, less than the distance that the floating valve 7 is driven upward by the control wheel 9 after it rises).

[0022] To prevent the cylinder on one side of the floating valve 7 from directly contacting the sharp point of the arrowhead, thus avoiding jamming, the circular block is designed to slide slightly diagonally up or down towards the sides of the floating valve 7. A spring is used for reset. This way, if it hits the sharp point of the arrowhead, it will slide up or down towards the floating valve 7, thus avoiding the collision and achieving the desired avoidance effect. The elbow design at one end of the detection tube 4 can be made thinner to make the changes in the liquid level detected above more obvious.

[0023] As described above, when the liquid level in detection tube 4 rises, the floating valve 7, under the control of control tank 25, can move upward, simultaneously causing control valve 8 to move upward as well. The upward movement of control valve 8 has two effects: firstly, a control bar 16 extends from one side of control wheel 9, and the control bar 16 is supported by a spring 26; control valve 8 is positioned precisely on one side of control bar 16, as shown in the attached instruction manual. Figure 2 As shown, at this time, the two are not in contact. Since the control valve 8 will move upward under the action of the floating valve 7, it will contact the control bar 16, causing the control bar 16 to move inward. Figure 2(The direction in the middle is to the left). Control valve 8 can also drive regulating valve 27 to move upward. Control valve 8 extends into the gas pipe 10 on one side, and a slidable regulating valve 27 is slidably mounted on its surface. There is an adapter spring 28 between regulating valve 27 and control valve 8. The function of adapter spring 28 is to ensure that regulating valve 27 can adapt regardless of whether control valve 8 moves upward or downward. As regulating valve 27 moves upward, it blocks the lower part and releases the upper part (as shown in the instruction manual). Figure 2 As shown, the air supply pipe 10 supplies air from the top to the middle, and has two air outlet directions, one above and one below. The two air outlet directions are respectively provided with annular protrusions, which can fit with the upper and lower sides of the adjusting rod. The adjusting valve 27 moves upward and naturally blocks the lower part, so that the air supply pipe 10 supplies air from the top (the same applies). The adjusting valve 27 moves upward and causes the air supply pipe 10 to extend to the middle for input and output upward, extending upward to the inside of the frame 1 and reaching the top of the pressure valve 11.

[0024] Above the pressure valve 11 is a sealing gasket that slides inside the gas supply pipe 10. The gas supply pipe 10 does not generate gas itself, but rather supplies gas through an external device. In this solution, the external device is an air compressor, which supplies gas to the gas supply pipe 10. Below the pressure valve 11 is a second spring, as shown in the attached instruction manual. Figure 1 and 2 As shown, spring number two supports the pressure valve 11 inside the gas supply pipe 10. Since the elastic force of spring number two is much smaller than that of the matching spring 28, as the equipment continuously supplies gas to the gas supply pipe 10, spring number two is forced to be compressed, causing the pressure valve 11 in this design to move downwards. When the pressure valve 11 reaches a certain position, it releases gas. Because a connecting groove 29 is provided in the position where the gas supply pipe 10 connects to the inside of the frame 1 (i.e., a connecting groove 29 is provided inside the frame 1), the connecting groove 29 is a groove recessed outwards in an annular shape. The outer diameter of this groove is larger than that of the pressure valve 11, so gas is released when it reaches this position. A connecting port 30 is provided in the middle of the pressure valve 11, which connects to the connecting groove 29. Therefore, the gas released from the connecting groove 29 can reach the connecting port 30 (the connecting port 30 is located below the sealing gasket and connects to a flexible hose). A flexible hose (the hose is very thin, as per the instruction manual) is connected to the side of the pressure valve 11. Figure 1 and 6 The hose is shown, as per the instruction manual. Figure 6 The back of the unblocking block 12 is a flexible hose that can connect to the interior of the unblocking block 12. (Since the gas delivery structure of this solution is in the shape of a pipe, many pipe structures cannot be completely cut, so they are not all shown.) In other words, the gas in this solution eventually reaches the unblocking block 12.

[0025] As per the instruction manual Figure 1 As shown, the unblocking block 12 is an incomplete circle, and the groove on the frame 1 is also a circular groove. This restricts the unblocking block 12 to rotate around the center of the incomplete circle. (See the instruction manual attached.) Figure 1 The structure of the side of the unclogging block 12 is not shown in the manual, so here is a brief description: The two sides of the unclogging block 12 are cylinders, and the centers of these two cylinders coincide with the center of the unclogging block 12. The frame 1 also has grooves for the rotation of the corresponding cylinders. A torsion spring is fitted onto each cylinder. The function of the torsion spring is to allow the unclogging block 12 to rotate under the action of the torsion spring, as shown in the attached manual. Figure 1 Perform a reset.

[0026] The above describes how the pressure valve 11 moves downward under the action of gas. Since the control bar 16 is squeezed by the control valve 8, it will contact the top of the pressure valve 11. The above describes how the pressure valve 11 moves downward, but it doesn't explain how the pressure valve 11 returns to its upward position. The elasticity of the second spring is clearly insufficient. The control bar 16 slides on the control wheel 9. As the control wheel 9 rotates, the control bar 16 also rotates. Because the control wheel 9 rotates relatively slowly, it is only when the control bar 16 contacts the control bar that it returns to its upward position, as shown in the attached instruction manual. Figure 6 As shown, the instruction manual is attached. Figure 6 The interior of frame 1 is cut out and shown, revealing the mechanism that will be introduced soon. This allows the pressure valve 11 to move both downwards and upwards.

[0027] As per the instruction manual Figure 6 As shown, a circular array of drive blocks 14 is provided on the edge of the unblocking block 12. One side of the drive block 14 is inclined. A transverse sliding block 15 is provided laterally on the edge of the pressure valve 11. A small spring is provided on the edge of the transverse sliding block 15. The spring force of this spring is large, greater than the torsion spring force on the edge of the unblocking block 12. A one-way tooth is provided on one side of the unblocking block 12. A one-way block 23 contacts the one-way tooth. The one-way block 23 slides on the extension frame 24. Since one side of the extension frame 24 is circular, it is exactly on one side of the control bar 16. The sliding of the control bar 16 causes the extension frame 24 to move and contact the one-way tooth on the edge of the unblocking block 12, so that the unblocking block 12 can only rotate counterclockwise (see instruction manual). Figure 1 (From the perspective of the angle), when the horizontal moving block 15 moves downwards and just contacts the inclined surface of the driving block 14, since the unblocking block 12 is already in contact with the one-way teeth, it cannot rotate clockwise. It can only cause the horizontal moving block 15 to move horizontally. After the horizontal movement, the horizontal moving block 15 is below the driving block 14. At this time, the driving block 14 blocks the top of the horizontal moving block 15. Since the pressure valve 11 described above will reset upwards, it will drive the unblocking block 12 to rotate upwards. When it reaches a certain angle, the two will separate, as shown in the instruction manual. Figure 6As shown, when the pressure valve 11 moves downward and then resets upward, it will continue to cause the unblocking block 12 to rotate.

[0028] The previous section introduced that the angle of the unblocking block 12 in this solution can be adjusted under the action of the pressure valve 11. However, the rotation angle of the control bar 16 in this solution is very slow. Since the first angle adjustment faces a whole surface of clay, it is necessary to blow air onto this entire surface to achieve the effect of covering and unblocking. During the return process of the horizontal moving block 15, the interior of the unblocking block 12 can be adjusted. The unblocking block 12 has a switching valve 21 inside. The switching valve 21 has a switching channel 22 with two outlets. As the switching valve 21 rotates, the switching channel 22 can adjust to different outlets to output air (the two outlets of the switching channel 22 only differ in air output width). Below the switching valve 21 It has a slot, on which a through rod 19 is attached. The through rod 19 slides through one side of the unclogging block 12 (the two slide in a sealed manner). Therefore, the left and right movement of the through rod 19 can cause the switching valve 21 to rotate. One side of the switching valve 21 extends to the outside of the unclogging block 12 and contacts the arc-shaped strip 18. One side of the arc-shaped strip 18 extends and is fixed to the frame 1 and is stationary. A protrusion is provided at the inner arc of the arc-shaped strip 18, which allows the through rod 19 to slide towards the switching valve 21 when the through rod 19 rotates. That is, every time the angle of the unclogging block 12 is adjusted, the through rod 19 will slide towards the switching valve 21. Below the through rod 19, as shown in the instruction manual... Figure 3 The device shown has a release block with a corresponding notch above it. Once moved towards the switching valve 21, it will jam the through rod 19, preventing it from moving towards the release rod 13. At this point, the internal spring 20 will be compressed. Removing the release block will allow the through rod 19 to move as shown in the instruction manual. Figure 3 As shown, it extends quickly; instruction manual attached. Figure 3 After being unplugged, channel 22 becomes a very narrow channel.

[0029] As mentioned above, the downward movement of the pressure valve 11 is achieved by gas, while the upward movement is achieved by the control bar 16. Since the control bar 16 rotates relatively slowly, the pressure valve 11 moves downward and then briefly moves up and down under the action of the second spring. This brief up-and-down movement does not cause the unblocking block 12 to rotate. This allows the solution to have a setting where the unblocking block 12 stops rotating for a period of time. At this time, the horizontal moving block 15 can be pulled out by briefly moving up and down, making the air outlet of the switching channel 22 narrow. This allows for a large area of ​​air to be released first after adjusting the angle, followed by a small area of ​​air released without moving. This achieves the effect of first blowing on the large block and then continuously releasing air to the small area, forming a gradual disintegration effect. This allows the clay to be continuously penetrated and unblocked. This is the significance of this solution.

[0030] To prevent the downward movement of the horizontal moving block 15 from causing the release block to move, while allowing the horizontal moving block 15 to move the release block within a small upward range, a rotating reciprocating block 17 is provided on one side of the horizontal moving block 15. However, the reciprocating block 17 needs to be supported by an extension of the horizontal moving block 15 below, allowing it to rotate upwards instead of downwards. The release lever 13 is rotatably positioned on one side of the unblocking block 12, along the final downward trajectory of the reciprocating block 17. This allows the downward movement of the reciprocating block 17 to cause it to move upwards (while the horizontal moving block 15 moves simultaneously), passing above the contact lever and reaching below it. As the horizontal moving block 15 moves upwards, it causes the release lever 13 to rotate counterclockwise. (See attached instruction manual.) Figure 3 From this perspective, the edge of the release lever 13 overlaps to form a release block. The release block is vertically slidably positioned on one side of the unblocking block 12, thus causing the contact block to move downwards and disengage from the through lever 19, allowing the through lever 19 to be released. This is the significance of designing the reciprocating block 17. To achieve the effect of the structure above, this solution requires torsion springs to be installed on one side of the rotation center of the reciprocating block 17 and the contact lever. Torsion springs are originally present, but due to the limitations of the instruction manual... Figure 3 Viewed from a certain angle, the torsion spring is not visible, but in fact, all have a torsion spring. The rotation center of the release lever 13 is in the middle of the release lever 13, as shown in the instruction manual. Figure 3 As shown, the release lever 13 has a distinct circle in the middle, which is the rotation center of the release lever 13. In order for the movement range of the reciprocating block 17 to cover the release lever 13, the release lever 13 needs to be positioned slightly below the vertical movement trajectory of the reciprocating block 17. This is because the release lever 13 itself can rotate with the unblocking block 12, so that the rotation of the release lever 13 will not affect the movement of the reciprocating block 17.

[0031] In summary, the unclogging block 12 in this solution can be adjusted in angle and paused for a period of time. The first adjustment allows the unclogging block 12 to spray gas over a large area, thus unclogging the clay in the adjusted area. Because the unclogging block 12 pauses for a period of time, it unclogging a small area in the middle of the clay, and this unclogging continues. Finally, the angle is adjusted again. (See the instruction manual attached.) Figure 4 The top of frame 1 needs to be connected to the hopper for placing clay so that the clay can be transported into the interior of frame 1.

[0032] After final unblocking, this solution will be reassessed, causing the floating valve 7, control valve 8, and control bar 16 to reset. Because control bar 16 resets, the extension frame 24 also resets. The extension frame 24 also has a spring-loaded reset mechanism. The extension frame 24 slides along the left-right movement direction of control bar 16, and a supporting sliding structure is provided inside the frame body 1. Thus, under the action of the spring in the extension frame 24, the one-way block 23 is pulled out (because the one-way block 23 has a sliding distance on the extension frame 24, and one side of the one-way block 23 is also supported by a spring), allowing the unblocking block 12 to reset. The torsion spring on the side of the unblocking block 12 allows it to reset to its initial position, as shown in the attached instruction manual. Figure 1 As shown in the figure, the position of the unblocking block 12 is on one side of the frame 1. In fact, the unblocking block 12 can also be designed in the middle of the frame 1. Considering that the frame 1 is too long, it is only necessary to set a motor drive on the control wheel 9.

[0033] A conveying mechanism is provided in the middle of the frame 1. The conveying mechanism includes a conveying shaft 2, a conveying plate 3, and a detection tube 4. The conveying shaft 2 is rotatably located in the middle of the frame 1. The detection tube 4 is located inside the conveying shaft 2. One end of the detection tube 4 is connected to a squeezing tube 5. One side of the squeezing tube 5 contacts a squeezing frame 6. A control mechanism is provided on one side of the detection tube 4. The control mechanism includes a floating valve 7, a control valve 8, and a control wheel 9. The floating valve 7 is slidably located on one side of the detection tube 4. An air supply pipe 10 is provided on the side of the frame 1. A pressure valve 11 is slidably provided at one end of the air supply pipe 10.

An arc-shaped bar 18 is integrally mounted inside the frame 1, and a through rod 19 is attached to the surface of the arc-shaped bar 18. The through rod 19 is slidably mounted on one side of the unblocking block 12, and an internal spring 20 is mounted on one side of the through rod 19. A switching valve 21 is rotatably mounted inside the unblocking block 12, and a switching channel 22 is opened in the middle of the switching valve 21. The through rod 19 is attached to the bottom of the switching valve 21. One-way teeth are provided on the edge of the unblocking block 12, and one-way blocks 23 overlap the surface of the one-way teeth. An extension frame 24 is slidably arranged inside the frame 1.

[0034] This embodiment provides a sand barrier laying mechanism, as shown in the attached instruction manual. Figure 4As shown in the previous embodiment, the air supply pipe 10 can also convey downwards, which means conveying to the air outlet pipe 36. Since the lower part of the air supply pipe 10 is connected to the air outlet pipe 36, and the outlet of the air outlet pipe 36 is located at the bottom, the clay conveyed by the conveying shaft 2 will reach above the laying wheel 35. As the laying wheel 35 rotates, the clay is scattered and splashed, achieving the effect of covering the sand with a thin layer of clay. A motor is installed below the laying wheel 35, and the rotation angle of the laying wheel 35 is ninety degrees, thus causing some clay to splash onto the inner side of the frame 1 (the frame 1 in this solution has other structures, but these are not shown in this solution, making it appear empty; in reality, there is also a place to store clay). (Structures such as bucket and overall lifting push rod), so the air outlet pipe 36 can blow away the clay remaining on the frame 1. In the previous embodiment, only one section of the frame 1 was shown. In fact, the conveying plates 3 set on the conveying shaft 2 can be arranged in an array inside the frame 1. In one embodiment, there is one group. Multiple groups of transverse conveying plates 3 are set on one conveying shaft 2 and a detection pipe 4 is set. Similarly, there are multiple groups of extrusion pipes 5 arrayed. There are also two unblocking blocks 12, symmetrically arranged on the left and right sides of the frame 1. There are two laying wheels 35. The laying wheels 35 rotate on one side of the frame 1. An air outlet pipe 36 is set on one side of the frame 1. One end of the air outlet pipe 36 is connected to the air supply pipe 10.
