Description

Technical Field

[0001] The invention relates to a paving machine, in particular to an on-site sand filling paving machine, belonging to the technical field of desert control equipment. Background Art

[0002] Sand barriers are effective engineering sand fixation measures to reduce wind speed and fix the sand surface. Existing sand barriers are mainly formed by manually filling sand into sandbags and laying them on the desert to form mechanical sand barriers. Reeds and straw are used for laying, and strips or grids are laid to form barriers to prevent sand flow, which plays a role in preventing wind and sand. Due to the uneven surface of the sand, traditional desert control methods usually rely on manually laying sand barriers. This method is not only inefficient, but also has high labor costs. In order to improve the efficiency and effectiveness of desert control, it is necessary to develop an automated and efficient laying equipment.

[0003] In the prior art, there is a continuous wing-bag sand barrier laying machine disclosed in publication number CN108316279A, which includes a frame and a sand barrier laying system arranged on the frame; the sand barrier laying system includes: a sand taking unit for collecting sand and placing the collected sand on a sand-filled cloth, a bag making unit for sewing the sand-filled cloth with sand to form a wing-bag, a sand filling unit for filling the wing-bag with sand during the bag making process of the bag making unit, and a laying unit for continuously laying the filled wing-bag. The invention integrates sand taking, bag making, sand filling and laying in one body, and forms a continuous sandbag with wings; it can significantly reduce wind speed, reduce wind erosion on the ground surface, greatly improve working efficiency, reduce the labor intensity of operators, have good laying quality, and have a relatively stable working state after continuous operation. However, in actual use, although the existing laying machine can realize the installation of sandbags and the filling of sandbags, when the existing laying machine installs the sandbags, it is necessary to complete the installation of the sandbags first and then the filling of the sandbags, that is, it is impossible to realize the installation and filling of the sandbags at the same time, which leads to low actual laying efficiency, and the installation of the sandbags cannot be targeted according to the specific required laying length, that is, the sandbags cannot be cut to an appropriate length, so as to better meet different laying requirements. Secondly, when filling the sandbags with sand, the method used is to fill the sandbags with sand by cooperating with a sand shovel and a sand collector. Although this method can fill a certain amount of sand into the sandbags, it cannot ensure the sand filling rate and cannot fill the sand continuously and evenly, which leads to the sand filled in the sandbags often being unevenly distributed, and the laid sand barrier sandbags cannot play a good sand prevention and sand fixation effect. In addition, the laid sand barrier sandbags are often equipped with biological seed ropes so that the laid sand barrier sandbags can grow green plants to further fix the sand. However, the existing paving machines can only fill the sand into the bags when filling the sand, and additional water resources are needed to irrigate after laying to keep the sand moist, which is difficult to achieve in desert areas where water resources are scarce. Based on this, the present invention proposes an on-site sand filling and paving machine. Summary of the invention

[0053] Furthermore, a plurality of water spraying chambers 217 are provided on the wall of the sand filling spiral conveying pipe 213, and a water guide pipe 215 is inserted in the water tank 29. One end of the water guide pipe 215 located outside the water tank 29 is connected to the wall of the sand filling spiral conveying pipe 213, and the water guide pipe 215 is communicated with the water spraying chamber 217, so that the water in the water tank 29 can be transported to the water spraying chamber 217 through the water guide pipe 215 for spraying, so that the sprayed water can be mixed with the sand and soil to ensure that the sand and soil have a certain humidity. It should be noted that one end of the water guide pipe 215 located in the water tank 29 is connected to a water pump, which can sink to the bottom of the water tank 29 by the gravity of the water pump itself, so that the water in the tank can be easily pumped out.

[0056] Furthermore, the front end of the pipe opening of the sleeve 42 is integrally connected with a beveled pipe head 49 , so that the opening of the opened sand barrier belt can be sleeved on the beveled pipe head 49 , and then can be conveniently sleeved on the pipe body of the sleeve 42 .

[0057] like Figure 1 , Figure 3 , Fig.10 and Fig.11 As shown, the reverse rotation unit of the rolling moving assembly 5 includes a docking rotating rod 55, a driving bevel gear 56 and a steering bevel gear 57.

[0058] Furthermore, the reverse driving unit of the rolling moving assembly 5 includes a driven rotating wheel 58, a transmission belt 59, a driving rotating wheel 510, a rolling driving gear 511 and a rolling motor 512. The driven rotating wheel 58 is respectively coaxially fixedly connected to one end of the rolling rotating rod 54 located outside the rolling outer frame 51. The body of the rolling motor 512 is embedded in the outer wall of the rolling outer frame 51. The outer wall of the rolling outer frame 51 is also provided with two sets of meshingly connected rolling driving gears 511, one of which is coaxially fixedly sleeved on the rotating shaft of the rolling motor 512, and the other rolling driving gear 511 is coaxially fixedly sleeved on the rotating shaft of the rolling motor 512.

[0059] like Figure 1 , Figure 3 , Fig.12 and Fig.13 As shown, the negative pressure adsorption unit of the transmission and cutting component 6 includes two negative pressure adsorption plates 64, which are symmetrically distributed and connected to the two ends of the pipe mouth of the hollow adsorption tube 61. A hollow cavity is opened in the plate of the negative pressure adsorption plate 64, and a plurality of negative pressure adsorption holes 65 are opened on the inner side of the negative pressure adsorption plate 64. The negative pressure adsorption holes 65 are connected with the two end pipe mouths of the hollow adsorption tube 61 through the hollow cavity, so that on the basis of the hollow adsorption tube 61 providing a supporting connection function, the hollow adsorption tube 61 can also evacuate the hollow cavity of the negative pressure adsorption plate 64, thereby generating a negative pressure adsorption force at the negative pressure adsorption holes 65, so that the upper and lower belt bodies of the sand barrier belt can be attached to the inner plate surface of the negative pressure adsorption plate 64, that is, the belt mouth of the sand barrier belt can be opened, so that it can be easily mounted on the sleeve 42;

[0060] Furthermore, the hot pressing plate unit of the transmission and cutting assembly 6 includes a pneumatic push rod 69 and a clamping hot pressing plate 66. The pneumatic push rod 69 is respectively connected to the two ends of the hollow clamping tube 62. The movable end of the pneumatic push rod 69 is fixedly connected to the back plate surface of the clamping hot pressing plate 66. The inner plate surface of the clamping hot pressing plate 66 is provided with a hot pressing convex strip 67 and a hot pressing groove 68. The hot pressing convex strip 67 and the hot pressing groove 68 provided on the upper and lower clamping hot pressing plates 66 are arranged in a staggered shape, so that on the basis of providing a supporting connection function for the hollow clamping tube 62, the hollow clamping tube 62 can also push the pneumatic push rod 69 to retract and retract through the adjustment of the internal air pressure, that is, it can realize the opening and closing adjustment of the two clamping hot pressing plates 66. When the two clamping hot pressing plates 66 are closed together, a clamping hot melt of the sand barrier belt body can be formed, which cooperates with the convex and concave of the hot pressing convex strip 67 and the hot pressing groove 68. The slot clamping action can further improve the firmness of the hot-melt sealing part and make it difficult to stretch open; it should be noted that the length of the plate body of the clamping hot pressure plate 66 is equal to the diameter of the turntable 41, and the length of the cutting blade 610 is half the length of the plate body of the clamping hot pressure plate 66, so that when the two clamping hot pressure plates 66 are closed, the cutting blade 610 only cuts off the sleeved sand barrier belt body, and because the rolling moving component 5 is capable of synchronously rolling and moving the sand barrier belts on the tube bodies of the two sleeves 42, when a certain length of sand barrier belt is sleeved inwardly on the tube body of one of the sleeves 42, the same length of sand barrier belt is pushed outwardly on the tube body of the other sleeve 42. Therefore, when the sand barrier belt sleeved inwardly on the tube body of one of the sleeves 42 is cut off and hot-melt sealed, the end band mouth of the sand barrier belt on the tube body of the other sleeve 42 can be hot-melt sealed at the same time.

[0061] like Figure 1 , Figure 2 , Figure 3 and Fig.14 As shown, the sand barrier belt roll 7 is rotatably installed in a suspended state on a belt roll support frame 71, and the belt roll support frame 71 is fixedly supported on the supporting base plate 2. The front end of the transmission and cutting assembly 6 is connected to a guide rod 10, and the sand barrier belt body transported by the sand barrier belt roll 7 bypasses the guide rod 10, so that the sand barrier belt roll 7 can rotatably transport the sand barrier belt on the belt roll support frame 71, and the sand barrier belt can be horizontally sleeved on the tube body of the sleeve 42 through the action of the guide rod 10.

[0062] Furthermore, the support base plate 2 is also connected with a conveyor belt 8 and a guide placement component 9, the guide placement component 9 is located on one side of the inclined lower end of the conveyor belt 8, and the inclined upper end of the conveyor belt 8 is clamped in the through slot opened in the equipment box 22, so that the sand barrier belt filled with sand can be output through the through slot, and the sand barrier belt filled with sand can be transported along the conveyor belt 8, and during the transportation process, the sand barrier belt filled with sand passes through the guide placement component 9 for guide placement, so as to ensure that the sand barrier belt filled with sand can be placed at a preset position;

[0063] Furthermore, the guide placement assembly 9 includes a guide rail 91, a guide frame 92, a guide roller 93 and a laser linear measuring instrument 94. The guide rail 91 is fixedly connected to the supporting base plate 2, the bottom of the frame of the guide frame 92 is fixedly connected to the slider of the guide rail 91, the guide roller 93 is rotatably connected to the frame of the guide frame 92 in an up and down distribution, and the laser linear measuring instrument 94 is installed in the middle part of the horizontal frame of the guide frame 92 so that the laser linear measuring instrument 94 can be aligned with the preset path for laying the sand barrier belt. When the laying machine deviates from its position during the forward movement, the guide rail 91 can drive the guide frame 92 to adjust its position to ensure that the laser linear measuring instrument 94 can always be aligned with the preset path for laying the sand barrier belt, that is, to ensure that the sand barrier belt filled with sand can be accurately placed at the preset position.

[0064] Working principle: the sand barrier belt roll 7 is rotatably connected to the belt roll support frame 71, and the sand barrier belt can be horizontally mounted on the tube body of the sleeve 42 through the action of the guide rod 10. When the belt body of the sand barrier belt passes through the transmission and cutting assembly 6, the hollow adsorption tube 61 is used to evacuate the hollow cavity of the negative pressure adsorption plate 64, and then a negative pressure adsorption force is generated at the negative pressure adsorption hole 65, so that the upper and lower belt bodies of the sand barrier belt can be attached to the inner plate surface of the negative pressure adsorption plate 64, that is, the belt mouth of the sand barrier belt can be opened. Under the action of the transmission conductor slide rail 63, the hollow adsorption tube 61 and the hollow clamping tube 62 are driven to move, so that the opened sand barrier belt can be mounted on the tube body port of the sleeve 42. At this time, the sand barrier belt can be continuously mounted on the tube body of the sleeve 42 in cooperation with the action of the rolling moving assembly 5. After a certain length of mounting, the sand barrier belt is pressed by the hot pressing plate unit. The belt body can be clamped, and the sand barrier belt can be cut off under the action of the cutting blade 610 during clamping, and the cut-off part can be hot-melt sealed by the hot pressing plate unit to form a biological integrated sand barrier, and the rolling rotating rod 54 on the upper and lower sides of one of the sleeves 42 can be driven to rotate in the opposite direction through the reverse driving unit, thereby driving the rolling roller 53 on the upper and lower sides of one of the sleeves 42 to rotate in the opposite direction, which can form a rolling movement of the sand barrier belt body sleeved on the sleeve 42 body, and under the action of the reverse rotation unit, the two horizontally connected rolling rotating rods 54 can be rotated in the opposite direction, that is, the rolling roller 53 can roll the sand barrier belt body on one of the sleeves 42 body inwardly, and at the same time, the sand barrier belt body on the other sleeve 42 body can be pushed outwardly, which can facilitate the control of the sleeve of the sand barrier belt and the sand filling of the sand barrier belt;

[0065] During sand filling, the sand scooped up by the sand conveying crawler 3 falls into the sand collecting bucket 24, and the sand in the sand collecting bucket 24 is transported to the sand storage box 28 for storage through the sand storage spiral conveying pipe 26, and the stored sand can be transported to the sand guiding bucket 211 through the sand guiding spiral conveying pipe 210, so that the sand can be poured into the sand barrier belt through the sand filling spiral conveying pipe 213, and the sand filling spiral conveying pipe 213 is extended into the tube of the casing 42, and then the sand in the sand storage box 28 is transported to the sand guiding bucket 211, and then the sand can be transported to the sand filling spiral conveying pipe 211 through the sand guiding telescopic hose 212. 3, so as to realize the uniform speed injection of sand into the sand barrier belt, and in the process of injecting sand, the water in the water storage tank 29 can be simultaneously sprayed into the sand barrier belt along the pipe wall of the sand injection spiral conveying pipe 213, and the water in the water storage tank 29 is transported to the water spraying chamber 217 through the water guide pipe 215 for spraying, so that the sprayed water can be mixed with the sand, ensuring that the sand has a certain humidity, and when one of the sleeves 42 with the sand barrier belt is injected with sand, the other sleeve 42 can be used to install the sand barrier belt, so that the installation of the sand barrier belt and the injection of sand into the sand barrier belt can be carried out at the same time, thereby improving the efficiency of on-site sand injection and laying;

[0066] The sand barrier belt filled with sand is output through the through groove and transported along the conveyor belt 8. During the transportation process, the sand barrier belt filled with sand passes through the guide placement component 9 for guidance and placement, and is aligned with the preset path for laying the sand barrier belt through the laser linear measuring instrument 94. When the laying machine deviates from its position during the forward movement, the guide slide rail 91 can drive the guide frame 92 to adjust its position to ensure that the laser linear measuring instrument 94 can always be aligned with the preset path for laying the sand barrier belt, that is, to ensure that the sand barrier belt filled with sand can be accurately placed at the preset position.
