Description

Technical Field

[0001] This invention relates to the field of grass checkerboard laying, and more particularly to an intelligent grass checkerboard laying device. Background Technology

[0002] Straw grids are made by laying straw stalks (rice straw or wheat straw) in a grid pattern to increase the roughness of the sandy surface, thereby playing a role in windbreak and sand fixation, helping the survival of sand-fixing plants, and achieving the effect of sand control.

[0003] In the existing process of laying straw checkerboard, it is usually necessary to manually lay the straw on the sand and then operate straw pressing equipment to press the straw into the sand layer. However, this method not only consumes a lot of manpower, but also has low overall laying efficiency. In addition, the straw is usually transported to the sandy area in the form of bundles. The straws inside the bundles are often tangled and tightly compacted. Before laying, a lot of manpower is needed to disassemble and disperse them so that the required number of straws can be laid on the sand one by one by hand before the subsequent straw pressing operation is carried out, which further increases the laying difficulty and time cost.

[0004] In summary, this application proposes an intelligent grass checkerboard laying device to improve the aforementioned technical problems. Summary of the Invention

[0005] In order to overcome the shortcomings of existing laying methods, which not only consume a lot of manpower and have low overall laying efficiency, but also require a lot of manpower to dismantle and disperse the straw before laying the required number of straws on the sand, this invention provides an intelligent straw grid laying device.

[0006] The technical solution is as follows: An intelligent grass grid laying device includes a grass pressing machine body and a grass pressing disc; the grass pressing machine body is rotatably connected to the grass pressing disc; it also includes a feeding bin; the grass pressing machine body is fixedly connected to the feeding bin for placing grass rolls; the feeding bin is rotatably connected to a bin door; the bottom of the feeding bin has a through hole, and a feeding pipe is connected to the through hole; the feeding pipe is connected to a conveying pipe; a grass pressing groove is opened at the lower end of the conveying pipe, and the grass pressing disc is located at the grass pressing groove; a feeding roller is rotatably connected to the upper side of the feeding pipe; several hook plates are fixedly connected to the feeding roller, and the hook plates are set as elastic metal sheets; several conveying rollers are rotatably connected inside the feeding pipe; a first conveyor belt is rotatably connected to the upper side of the conveying pipe; two second conveyor belts are rotatably connected to the lower side of the conveying pipe, respectively located at the front and rear sides of the grass pressing groove; the feeding bin is connected to a dispersing component for dispersing grass rolls.

[0007] Optionally, the width of the feed tube is set to gradually narrow from top to bottom.

[0008] Optionally, the conveying pipe is provided with a vertical section, and the vertical section is located between conveyor belt one and conveyor belt two.

[0009] Optionally, an inclined plate is provided at the through hole at the bottom of the discharge hopper.

[0010] Optionally, the dispersing assembly includes an electric push rod 1; two electric push rods 1 are fixedly connected to the left and right sides of the discharge bin; all the telescopic parts of the electric push rods 1 on the same side are fixedly connected to an extrusion plate; each extrusion plate is fixedly connected to several electric push rods 2; each telescopic part of the electric push rod 2 is fixedly connected to an insert rod that is slidably connected to the extrusion plate; several through holes are opened on the left and right sides of the discharge bin, and the positions of the insert rods and through holes correspond; each insert rod is provided with a grass hook.

[0011] Optionally, it also includes a compression plate; the hook part of the insertion rod is made of elastic material; and two compression plates corresponding to the positions of the hook part are fixed to the left and right sides of the compression plate.

[0012] Optionally, it also includes an electric push rod three and a lower pressure plate; the discharge bin is fixedly connected to the electric push rod three; the telescopic part of the electric push rod three is fixedly connected to the lower pressure plate.

[0013] Optionally, the feed pipe is equipped with an observation window.

[0014] Optionally, it also includes a bucket and a rotating plate; the bucket with its bottom flush with the bottom of the conveying pipe is fixedly connected to the conveying pipe; the bucket has several discharge holes; and a rotating plate is rotatably connected to each discharge hole via a torsion spring.

[0015] Optionally, the bucket is equipped with a blocking block.

[0016] The beneficial effects of this invention are: the dispersed straw stalks are conveyed by conveyor belts one and two in the conveying pipe until the straw stalks are conveyed to the pressing trough and contact the pressing disc. The pressing disc presses the straw stalks in the pressing trough into the sand, thereby realizing the automatic laying and pressing of straw stalks. Compared with the existing manual laying of straw stalks, it can save more manpower and improve the overall laying efficiency of straw grid.

[0017] By controlling the conveying speed of conveyor belt one to be faster than that of conveyor belt two, the straw conveyed by conveyor belt one can be gathered in the vertical section. This allows the separated straw to be gathered in the vertical section and connected together before being conveyed by conveyor belt two to the pressing disc. This increases the continuity of straw conveying and improves the integrity of the straw grid laying. It also prevents the straw from being unable to be continuously and evenly conveyed through the conveying pipe to the pressing disc, which would result in intermittent or discontinuous straw being pressed into the sand.

[0018] By having two extrusion plates move back and forth in opposite directions, the straw rolls in the discharge bin are compressed. The straw rolls are then hooked by the hooking part of the insert rod and pulled apart, thereby dispersing the tightly compressed straw rolls and reducing the tangling of the straws. This makes it easier to gradually separate and transport the straws for subsequent straw grid laying. Attached Figure Description

Detailed Implementation

[0021] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0022] Example 1: An intelligent grass checkerboard laying device, referring to Figures 1-8 As shown, it includes a grass presser body 1 and a grass press disc 2; the grass presser body 1 is rotatably connected to the grass press disc 2; It also includes a discharge bin 3, a feeding pipe 4, a conveying pipe 5, a feeding roller 6, a hook plate 7, a conveying roller 8, a first conveyor belt 9, a second conveyor belt 10, and a dispersing assembly; the main body 1 of the straw press is fixedly connected to the discharge bin 3; the discharge bin 3 is rotatably connected to a bin door 31; the bottom of the discharge bin 3 has a through hole, through which the feeding pipe 4 is connected; the feeding pipe 4 is connected to the conveying pipe 5; the lower end of the conveying pipe 5 has a straw pressing trough 52, and the straw pressing disc 2 is located at the straw pressing trough 52; the upper side of the feeding pipe 4 is rotatably connected to the feeding roller 6, and the feeding roller 6 is an electric roller, which is electrically powered. The moving roller consists of a motor and a roller, with the motor driving the roller to rotate; the feeding roller 6 is fixedly connected to four hook plates 7, and the hook plates 7 are made of elastic metal sheets; several conveying rollers 8 are rotatably connected inside the feeding pipe 4, and the conveying rollers 8 are electric rollers, which consist of a motor and a roller, with the motor driving the roller to rotate; a conveyor belt 9 is rotatably connected to the upper side of the conveying pipe 5; two conveyor belts 10 are rotatably connected to the lower side of the conveying pipe 5, and the conveyor belts 10 are located at the front and rear sides of the grass pressing trough 52 respectively; the discharge bin 3 is connected to a dispersing component.

[0023] The width of the feeding pipe 4 is set to gradually narrow from top to bottom, so that the small strands of straw entering the feeding pipe 4 can be gradually dispersed and conveyed, eventually reaching the required thickness of the straw.

[0024] The conveying pipe 5 is provided with a vertical section 53, which is located between the first conveyor belt 9 and the second conveyor belt 10. When conveying straw, by controlling the conveying speed of the first conveyor belt 9 to be faster than that of the second conveyor belt 10, the straw conveyed by the first conveyor belt 9 can be gathered in the vertical section 53, so that the separated straw can be connected together and conveyed to the pressing disc 2 by the second conveyor belt 10, thereby increasing the continuity of straw laying.

[0025] An inclined plate 32 is provided at the through hole at the bottom of the feeding hopper 3. The inclined plate 32 squeezes and scrapes the hook plate 7 to prevent the straw from staying on the hook plate 7 and thus avoids clogging the feeding pipe 4 and preventing the conveying work from being carried out.

[0026] The following are the specific operations for laying the straw checkerboard. First, the manual operator rotates and opens the door 31 of the feeding bin 3. Then, the straw rolls are placed into the feeding bin 3 and disassembled. The door 31 is then closed. Next, the straw rolls are dispersed by the dispersing component. Simultaneously, the dispersed straw rolls, under their own weight, come into contact with the feeding roller 6 on the lower side. Then, the feeding roller 6 is controlled to rotate clockwise from front to back. The feeding roller 6 drives the hook plate 7 to rotate. The hook plate 7 hooks the small strands of straw to separate from the straw rolls and rotates with the feeding roller 6, conveying the separated small strands of straw into the feeding pipe 4. The feeding roller 6 in the feeding pipe 4 is controlled to rotate, conveying the straw downwards. At the same time, the feeding pipe... The width of the feed pipe 4 gradually narrows from top to bottom. The small strands of straw entering the feed pipe 4 are gradually dispersed and conveyed as the feed roller 6 rotates, reaching the required thickness for straw laying. They then enter the feed pipe 5, where the dispersed straw is conveyed by the conveyor belt 9 and conveyor belt 10 until it reaches the pressing trough 52 and contacts the pressing disc 2. The main body 1 of the straw pressing machine is then manually operated to drive the pressing disc 2 to roll on the sand. The pressing disc 2 presses the straw at the pressing trough 52 into the sand, thus achieving automatic straw laying and pressing. Compared with the existing manual straw laying, this method saves a lot of manpower and improves the overall efficiency of straw grid laying.

[0027] Meanwhile, considering the varying degrees of entanglement and compactness among different straws within the straw roll, the separation resistance experienced by different straws differs during the separation and transport by the feeding roller 6 and conveying roller 8. This results in unstable conveying speeds of the separated straws, preventing continuous and uniform transport of the straws through the conveying pipe 5 to the pressing disc 2. Consequently, the straws pressed into the sand by the pressing disc 2 are intermittent or discontinuous, ultimately leading to gaps or voids in the laid straw grid, affecting the integrity of the overall structure and weakening its windbreak and sand-fixing effect. Therefore, the conveying pipe 5 is equipped with a vertical section 53, located between conveyor belt 9 and conveyor belt 10. During straw transport, the conveying speed of conveyor belt 9 is controlled to be faster than that of conveyor belt 10, allowing the straws transported by conveyor belt 9 to gather in the vertical section 53. This ensures that the separated straws can gather in the vertical section 53 and connect together before being transported by conveyor belt 10. The straw is fed to the pressing disc 2 to increase the continuity of straw conveying and improve the integrity of the straw grid laying. This prevents the straw from being conveyed continuously and evenly through the conveying pipe 5 to the pressing disc 2, which would result in intermittent or discontinuous straw pressed into the sand. Furthermore, during the conveying process of the separated straw by the conveying roller 8 and the conveyor belt 9, the straw may tilt or deviate. Tilted straw pressed into the sand has poor overall stability and is more prone to loosening under the action of wind, making the straw grid structure more fragile. By gathering the straw conveyed by the conveyor belt 9 to the vertical part 53, and making the height of the straw gathered in the vertical part 53 similar to the height of the conveyor belt 9, the tilted straw can be blocked when the conveyor belt 9 conveys the tilted straw to the vertical part 53. Then, under the continuous conveying of the conveyor belt 9, the tilted straw is pushed to rotate, straightened and conveyed to the vertical part 53, thereby reducing the tilt of the straw and improving the overall stability of the straw grid laying.

[0028] The dispersing assembly includes an electric push rod 111, an extrusion plate 112, an electric push rod 113, and an insert rod 114. Two electric push rods 111 are fixedly connected to the left and right sides of the discharge bin 3. Each extension part of all electric push rods 111 on the same side is fixedly connected to an extrusion plate 112. Several electric push rods 113 are fixedly connected to each extrusion part of each electric push rod 113. An insert rod 114 is fixedly connected to the extension part of each electric push rod 113. Several through holes are opened on the left and right sides of the discharge bin 3. The insert rod 114 is positioned corresponding to the through holes and passes through the extrusion plate 112, and is slidably connected to the extrusion plate 112. Each insert rod 114 is provided with a grass hook part 11401.

[0029] It also includes a pressing plate 115; the grass-hooking part 11401 of the insert rod 114 is made of elastic material; two pressing plates 115 are fixedly connected to the left and right sides of the pressing plate 112, and the pressing plates 115 correspond to the grass-hooking part 11401.

[0030] It also includes an electric push rod 121 and a lower pressure plate 122; the electric push rod 121 is fixedly connected to the upper side of the discharge bin 3; the lower pressure plate 122 is fixedly connected to the telescopic part of the electric push rod 121. By moving the lower pressure plate 122 down to press the straw, the straw is pushed to contact the feeding roller 6 on the lower side, thereby improving the overall conveying effect of the straw.

[0031] The conveying pipe 5 is equipped with an observation window 51, through which the conveying of the dispersed straw can be observed, thereby adjusting the conveying speed of the conveyor belt 9.

[0032] A pressure sensor is installed at the bottom of the feeding bin 3, which can detect the weight of the straw inside the feeding bin 3. When the number of straws in the feeding bin 3 drops to a threshold, it can intelligently issue an early warning to remind people to add new straw rolls.

[0033] The following are the specific working steps of the dispersing component. Considering that straw is mostly transported to sandy areas in the form of bundles, the straw inside the bundles is often tangled and tightly compacted, requiring a lot of manpower for dismantling and dispersing before laying. Therefore, after manually placing the straw bundles into the feeding bin 3, the electric push rod 111 is controlled to drive the two extrusion plates 112 to move back and forth in opposite directions. When the two extrusion plates 112 move towards each other, they extrude straw bundles in the feeding bin 3. During the extrusion of the straw bundles, the electric push rod 113 is simultaneously controlled to drive the insertion rod 114 to move and insert. Inside the straw roll, as the two extrusion plates 112 move in opposite directions, the straw roll is hooked by the hooking part 11401 of the insertion rod 114, pulling and dispersing it. This disperses the tightly compacted straw roll, reducing the tangling of the straws, so that the straws can be gradually separated and transported for subsequent straw grid laying. Furthermore, when the hooking part 11401 of the insertion rod 114 moves closer to the extrusion plate 112, the extrusion plate 115 scrapes the hooking part 11401, thereby pushing out the straws from the hooking part 11401 and preventing the straws from being constantly caught on the hooking part 11401, which would affect the subsequent straw transport.

[0034] At the same time, as the amount of straw in the feeding bin 3 decreases, the control extrusion plate 112 stops moving, and the control electric push rod 121 drives the lower pressure plate 122 to move down. The lower pressure plate 122 presses down the straw so that it contacts the feeding roller 6 on the lower side, thereby preventing the straw from being unable to contact the feeding roller 6 under its own gravity when there is less straw.

[0035] Example 2: Based on Example 1, referring to... Figures 7-8 As shown, it also includes a bucket 201 and a rotating plate 202; the bucket 201 is fixedly connected to the left side of the conveying pipe 5, and the bottom of the bucket 201 is flush with the bottom of the conveying pipe 5; the bucket 201 has several discharge holes 20101; the rotating plate 202 is rotatably connected to each discharge hole 20101 through a torsion spring.

[0036] The bucket 201 is equipped with a blocking block 20102 to prevent sand inside the bucket 201 from flowing out.

[0037] Based on the above embodiment 1, further considering that when the grass compaction disc 2 rolls and compacts grass on sandy ground, the terrain is uneven and some sandy areas contain gravel. When the grass compaction disc 2 passes over gravel, it is easily damaged, which in turn affects the subsequent laying of grass squares. Therefore, during the laying process, the bottom of the conveying pipe 5 and the bottom of the bucket 201 are in contact with the ground. When laying work is carried out, the grass compactor body 1 pushes the bucket 201 to first scrape the surface of the sand, removing the gravel on the surface, and when passing over some protrusions, it can shovel the protruding sand into the bucket 201. 1. When passing through sand pits and depressions, the rotating plate 202 on the bucket 201 is no longer restricted by the sandy surface and rotates towards the sand pits and depressions under the action of the torsion spring, thereby opening the discharge hole 20101. This allows the sand collected in the bucket 201 to flow into the sand pits and depressions through the discharge hole 20101, thereby filling them and improving the overall flatness of the sandy surface, thus improving the stability of the subsequent grass stalk laying. It should be noted that in some areas with many sand pits and depressions, sand is manually shoveled into the bucket 201 to fill the subsequent ground surface.

[0038] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
