Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery and equipment, and in particular to a grass grid laying device and a post-laying detection method. Background Art

[0002] Grass grids are a grid-shaped protective belt that plays a role in preventing wind and sand and conserving water. In the early stages of desert management, grass grids are needed to make sand barriers to fix sand, reduce the fluidity of the sand surface, and provide the premise for subsequent planting of plants.

[0003] Chinese invention patent, application publication number CN114457779A discloses a straw grid sand barrier laying mechanical device, which can realize the automation of the whole process of burying straw in sand, with less manual participation and high efficiency of burying straw.

DETAILED DESCRIPTION

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] like Figure 1 - Fig.10 As shown, the present invention provides a technical solution: a grass grid paving device, comprising a wheeled or crawler tractor 1, a chassis 101 located at the bottom of the tractor 1, a driving route detection component and a controller. In this solution, the driving route detection component includes but is not limited to the following three existing technologies for detecting the lateral offset of the vehicle. Specifically, the first is that the driving route detection component can be composed of a laser transmitter 10 fixed on the top of the tractor 1 and a lateral cursor rod (not shown in the figure) set on the sand to be paved. When the tractor 1 slides sideways, the lateral cursor rod will detect the offset of the tractor 1; the second is that the driving route detection component can detect the lane through a camera and image processing technology, determine whether the tractor 1 deviates from the lane and determine the offset; the third is that the driving route detection component can use GPS technology to track the vehicle position in real time and calculate the offset between the driving trajectory and the preset route.

[0053] like Figure 3As shown, a transmission rod 2 is arranged at the bottom of the chassis 101, and the transmission rod 2 includes two bent rods 202. In this solution, in order to reduce the overall volume of the laying device, the bent rod 202 is in a herringbone shape, and a fixed shaft is fixed between the tails of the two bent rods 202. A plurality of longitudinal pressure wheels 4 for rolling the longitudinally laid straw curtain into the soil are movably connected to the shaft body of the fixed shaft. The longitudinal pressure wheels 4 are located in the middle of the longitudinally laid straw curtain. A transverse adjustment member 3 is arranged on the outer side of the transmission rod 2. When the tractor 1 slides laterally, the transverse position of the transmission rod 2 is adjusted by the transverse adjustment member 3 so that the laid longitudinal straw curtain forms a straight line.

[0054] Specifically, Figure 3 As shown, the transmission rod 2 also includes a slider 204, a movable shaft 201 and a connecting shaft 203. A plurality of first driving members 205 are arranged between the slider 204 and the connecting shaft 203, and the two sides of the first driving member 205 are movably connected to the connecting shaft 203 and the slider 204 respectively. In this solution, the first driving member 205 is selected as a hydraulic cylinder. When the first driving member 205 is extended and retracted, it can drive the bending rod 202 to rotate around the movable shaft 201 to realize the lifting and lowering of the longitudinal pressing wheel 4. When the longitudinal pressing wheel 4 rises to the highest position, the longitudinal pressing wheel 4 is out of contact with the sand. When the longitudinal pressing wheel 4 drops to the lowest position, the tractor 1 drives the longitudinal pressing wheel 4 to rotate when moving forward, thereby pressing the middle part of the longitudinal straw curtain laid longitudinally, so that the two sides of the longitudinal straw curtain are tilted upward. It can be known that the tilting height of the two sides of the longitudinal straw curtain is related to the width of the straw curtain, and the specific tilting height depends on the prevention and control requirements of the sand, which is not limited in this solution.

[0055] like Figure 4 As shown, the lateral adjustment member 3 includes a limiting groove opened at the bottom of the chassis 101, and a slider 204 is movably arranged in the limiting groove. The limiting groove can be a center-shaped groove or a dovetail groove, and the slider 204 is correspondingly a center-shaped block or a dovetail block. The mutual cooperation between the special-shaped block and the limiting groove can realize the lateral movement of the slider 204 along the bottom of the chassis 101. A plurality of guide blocks 206 are fixed on the axis body of the movable shaft 201 extending from the bent rod 202, and a circular array is provided. The guide blocks 206 are adapted to the jacks of the fixed blocks on both sides of the chassis 101. It can be understood that such a setting can ensure that the movable shaft 201 moves laterally along the outer side of the chassis 101 without axial rotation. A second driving member 207 is fixed to the side of the chassis 101 on one side, and the telescopic end of the second driving member 207 is fixed to the end of the movable shaft 201. The second driving member 207 is selected as a hydraulic cylinder, and the second driving member 207 can drive the movable shaft 201 to move laterally when it is telescopic.

[0056] like Figure 1As shown, a longitudinal laying component 5 and a transverse laying component 6 are provided between the two curved rods 202. The longitudinal laying component 5 and the transverse laying component 6 respectively lay the longitudinal straw mat and the transverse straw mat and press them into the soil. In the forward direction of the tractor 1, the longitudinal laying component 5 is located in front of the transverse laying component 6, so that the grass grid is laid longitudinally first and then transversely.

[0057] Specifically, when the tractor 1 is moving, if there is a left (right) lateral sliding, the driving route detection component will detect the offset between the current driving trajectory and the set driving trajectory, and the controller will control the second driving component 207 to extend (shorten) to a distance equal to the deviation. The extension (shortening) of the second driving component 207 drives the movable shaft 201, the longitudinal laying component 5, the transverse laying component 6 and the longitudinal pressing wheel 4 to move synchronously, thereby ensuring that the laid and rolled longitudinal straw mats are in a straight line.

[0058] In order to prevent the movable axle 201 from shifting too much laterally, the position of the tractor 1 needs to be adjusted, such as Figure 2 As shown, pressure sensors 9 are fixed on the shaft bodies of the movable shaft 201 located on both sides of the bending rod 202. When the movable shaft 201 is displaced too much to both sides, the pressure sensors 9 on both sides will be squeezed against the side surfaces of the fixed blocks on the sides of the chassis 101. At this time, the controller controls the vehicle-mounted alarm system to remind the driver, and the driver can manipulate the vehicle to move laterally until the vehicle moves to the set track.

[0059] like Figure 4 - Figure 6 As shown, the longitudinal laying component 5 includes a longitudinal box 501, a plurality of unwinding shafts 504 and two rollers 505. The number of unwinding shafts 504 can be set to three, so that after a single laying, two squares will be formed in the horizontal direction. When it is set to four, after a single laying, three squares will be formed in the horizontal direction. In this solution, in order to reduce the overall volume of the laying device, the number of unwinding shafts 504 is set to two, so that its laying effect is referenced Fig.11 A roller 506 is fixed on the shaft body of roller 1 505, a motor 2 513 is fixed on the side of the longitudinal box 501, and the output end of the motor 2 513 is fixed to the end of one of the rollers 1 505, and a first gear 512 is fixed on the shaft bodies of the two rollers 1 505, and the two first gears 512 are meshed with each other. In this way, when the motor 2 513 drives one of the rollers 1 505 to rotate, the rotation directions of the two rollers 1 506 are opposite. Since the longitudinal straw curtain is rolled up on the shaft body of the unwinding shaft 1 504, and one side of the longitudinal straw curtain passes through the two rollers 1 506 after installation, when the two rollers 1 506 rotate, the longitudinal straw curtain on the shaft body of the unwinding shaft 1 504 is driven to be unwound. A cutting piece is arranged at the bottom of the longitudinal laying component 5. When the longitudinal straw curtain is laid, the longitudinal straw curtain is cut by the cutting piece.

[0060] In order to improve the cutting effect of the longitudinal straw mat, a vertical plate 502 and an inclined plate 503 are formed at the bottom of the longitudinal box 501. After the unrolled longitudinal straw mat is supported by the inclined plate 503, it falls through the discharge port formed by the vertical plate 502 and the inclined plate 503.

[0061] Among them, Figure 4 - Figure 6 As shown, the cutting member includes two first through slots 507 provided on the inclined plate 503 and a second through slot provided on the plate body of the vertical plate 502, a screw rod 508 is movably connected to the side of the vertical plate 502, a motor 1 511 is fixed to the side of the vertical plate 502, and the output end of the motor 1 511 is fixed to the end of the screw rod 508, two wire blocks 509 are movably screwed on the rod body of the screw rod 508, a transmission shaft is movably connected to the wire block 509 located in the longitudinal box body 501, a motor 3 is fixed to the side of the wire block 509, and the output end of the motor 3 is fixed to the end of the transmission shaft, a saw disc 510 is fixed to the shaft body of the transmission shaft, and it can be known that one side of the saw disc 510 extends into the first through slot 507, and the longitudinal straw curtain located outside the first through slot 507 is cut by the saw disc 510.

[0062] It can be understood that in this solution, the longitudinal straw mat is laid continuously because it is laid longitudinally first and then transversely. In this way, the longitudinal straw mat is cut by the saw disc 510 only after a single longitudinal laying of the longitudinal straw mat is completed.

[0063] like Figure 7-Figure 9 As shown, the transverse laying assembly 6 includes a transverse box 601, a second unwinding shaft 602, a fourth motor and a second roller. To achieve transverse laying of the transverse straw curtain, the second unwinding shaft 602 is arranged on the outer side of the transverse box 601, and its axis is parallel to the forward direction of the tractor 1. The transverse straw curtain is rolled up on the shaft body of the second unwinding shaft 602, and a second roller 605 is fixed on the shaft body of the second roller. The output end of the fourth motor is fixed to the end of the second roller. When the second roller 605 rotates, it drives the transverse straw curtain to be unwound. A transverse plate is fixed on the inner side of the transverse box 601, and a plurality of third driving members 606 are fixed on the plate body of the transverse plate. The third driving member 60 The telescopic end of 6 is fixed with a cutter 607 for cutting the transverse straw mat. In order to improve the cutting effect of the transverse straw mat, a feed port 603 is opened on the side of the transverse box 601, and a guide bevel 604 is arranged at the bottom of the feed port 603. When the transverse straw mat passes through the feed port 603, the inclined surface of the guide bevel 604 supports the transverse straw mat. A conveying member and a vertical pressing component are arranged at the bottom of the transverse box 601. The cut transverse straw mat is conveyed by the conveying member. When the cut transverse straw mat is transmitted to the bottom of the conveying member, the cut transverse straw mat is pressed by the vertical pressing component, thereby pressing the transverse straw mat into the soil.

[0064] like Fig. 9 As shown, the transmission member includes a motor 5 and a plurality of transmission shafts 608 distributed in a rectangular shape. The output end of the motor 5 is fixed to the end of one of the transmission shafts 608. Two transmission belts 614 with barbs formed on the outer surface are arranged between the transmission shafts 608. In this way, the transmission belts 614 can drive the transverse straw curtain to move synchronously when moving. Unlike the longitudinal straw curtain, the transverse straw curtain needs to be cut several times during the forward movement of the tractor 1, such as Fig.11 As shown, the length of a single cut transverse straw curtain is 2×L1+H, and this length can be determined by the number of rotations of the second roller 605. In order to enable the paving device to achieve a uniform grass grid specification during paving, in this solution, 2×L1=H.

[0065] When the device works reciprocatingly, grass grids can be laid on the sand.

[0066] To prevent the cut transverse straw mats from falling, two supporting plates are fixed at the bottom of the conveyor belt 614, and a movable cavity is formed between the supporting plates and the conveyor belt 614, wherein the supporting plates include a support plate 609 and a limiting plate 610, and the cut transverse straw mats are located directly above the supporting plate 609, and the limiting plate 610 guides the transverse straw mats on the top of the conveyor belt 614 to prevent them from being blocked in the gap between the side conveyor belt 614 and the transverse box 601, and gaps are formed between the two conveyor belts 614 and between the two supporting plates.

[0067] like Figure 7-Figure 9 As shown, the vertical pressing assembly includes a pressing plate 611, and a plurality of movable grooves are opened on both sides of the horizontal box 601. A plurality of extension plates 612 are fixed to the top of the pressing plate 611, and the extension plate 612 is located in the movable groove. A fourth driving member 613 is fixed to the top of the movable groove. The fourth driving member 613 is a hydraulic cylinder, and the telescopic end of the fourth driving member 613 is fixed to the top of the extension plate 612. It can be known that when the fourth driving member 613 drives the pressing plate 611 to move up and down, the pressing plate 611 moves through the gap formed between the two conveyor belts 614 and between the two supporting plates, thereby pressing the horizontal straw mat located between the two supporting plates into the soil.

[0068] like Fig.11As shown, in order to ensure that the width P of the grass grid laid each time is a certain value, a second gear 701 is fixed on the shaft of one of the rollers 505, and a third gear 702 is movably connected to the side of the longitudinal box 501 through a rotating shaft, and the second gear 701 is meshed with the third gear 702. A sensing sheet 703 is arranged on the side of the third gear 702, and a sensor 704 is fixed on the side of the transverse box 601 facing the third gear 702. The sensor 704 senses the sensing sheet 703. The gear ratio between the second gear 701 and the third gear 702 is determined according to the size of P. For example, if the width of the laid square is 1 meter, the second gear 70 1 rotates one circle to achieve the vertical straw curtain falling 20 cm, then, the gear ratio of the second gear 701 and the third gear 702 is set to 1:5, that is, after the second gear 701 rotates 5 circles, the third gear 702 rotates one circle. In this way, when the third gear 702 rotates one circle, the sensor 704 senses the sensor sheet 703, and the sensing signal is transmitted to the controller. The controller controls the fourth driving member 613 to move downward, so as to push the horizontal straw curtain that has been cut and is located at the bottom of the conveyor belt 614 downward through the pressing plate 611, so as to press the horizontal straw curtain into the sand. Finally, the controller controls the fourth driving member 613 to reset for the next work.

[0069] The present scheme also discloses a method for detecting the laid grass grids, which is based on scanning and comparing the laid grass grids with a scanning probe 8 arranged on the laying device. Specifically, in the present scheme, three scanning probes 8 are arranged and fixed on the side of the horizontal box 601 facing the longitudinal pressure wheel 4. The three scanning probes 8 respectively scan the rear and both sides of the laid grass grids, and the scanned image information is transmitted to the controller. The image information is analyzed by the central processing unit to judge whether the straw curtains in each grid are warped (no rolling or pressing is performed, and the longitudinal straw curtains or the transverse straw curtains are not warped). If it is found that the longitudinal straw curtains or the transverse straw curtains in the grid are not warped, the positioner in the controller locates the scanning position and notifies the subsequent personnel to reprocess the straw curtains outside the grid, thereby realizing the quality inspection of the laid grass grids.

[0070] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is limited by the attached embodiments and their equivalents.
