Description

Technical Field

[0001] This invention relates to the technical field of desertification control equipment, and in particular to an automatic X-shaped grass checkerboard laying machine. Background Technology

[0002] Desertification is a globally recognized challenge, and to effectively manage it, people have long created and adopted many effective desertification control methods. Among them, the five-in-one desertification control method in Shapotou, Zhongwei County, Ningxia, my country, which mainly uses straw checkerboard grids, has successfully solved the problem of stabilizing shifting sand. This method is hailed as the world's first desertification control project and has attracted the attention of the international environmental protection community.

[0003] As one of the most popular environmental governance topics in contemporary times, desertification control has been an ongoing process of exploration. Compared with manual sand fixation, mechanical sand fixation can improve efficiency, reduce costs, and is more suitable for working in harsh desert environments. Practice has proven that laying straw squares is widely recognized as the most effective method of engineering sand fixation. Straw squares are made by laying straw on sand and pressing it into the sand from the center using machinery, inserting it to a depth of 20-25 cm, with 10-15 cm protruding above the sand surface, forming a 1 m × 1 m square grid. However, the woven straw squares are relatively light, and when using machinery to lay them, it is difficult to precisely control the placement of each square on the ground. This easily leads to overlapping of straw squares and large gaps between them, significantly affecting the laying effect and weakening the sand control effect.

[0004] Based on the principle of grass checkerboard laying, this design aims to solve the problems of low efficiency, harsh working environment, and remote location of manual grass checkerboard laying, and to achieve the goal of advancing people and retreating sand as soon as possible. The grass checkerboard laying device is designed to realize the mechanization and automation of laying, saving manpower and material resources.

[0005] Currently, the desertification control machinery used for laying straw checkerboard mats is all large-scale, which has disadvantages such as being bulky, limited to a single terrain, difficult to maintain, and costly. Therefore, miniaturizing and lightening this type of machine can enable it to have a larger laying range, a simpler structure, and be easier to maintain. Summary of the Invention

[0006] The purpose of this invention is to provide an X-shaped grass checkerboard laying machine, which can lay the grass checkerboard as a whole by laying X-shaped grass mats, achieving horizontal and vertical integration, reducing manpower and the frequency of grass replacement.

[0007] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0008] An automatic X-shaped grass checkerboard laying machine includes the following steps:

[0009] (1) The track mechanism drives the machine to a suitable position and then stops above the work area;

[0010] (2) After the grass roll is rotated to the designated position, it is driven by the chains on both sides to the gear rack below. The gear rack rotates and moves down, driving the grass roll down to the space where the second layer is located.

[0011] (3) The second layer of grass brushes rotates, causing the grass curtain to unfold. When the grass curtain unfolds to the designated position, the sensor is triggered.

[0012] (4) Through gear and sprocket transmission, the lower worm gear is driven to work. The worm gear rotates and has a cutter on it to cut the straw mat. Then the worm gear has a crank-slider mechanism. The slider moves and the lower through slot opens, allowing the straw mat to fall below.

[0013] (5) The V-shaped sand shovels on both sides of the third layer move downwards, the X-shaped sand shovels move downwards, the VX-shaped sand shovels are inserted into the sand, the V-shaped sand shovels spread out to both sides in the sand, dig out sand troughs, and after the straw curtain falls into them, the V-shaped sand shovels on both sides move upwards, and the sand on both sides gathers and buries the straw curtain in them, and then the X-shaped sand shovels move upwards.

[0014] (6) Then repeat steps (1)-(6) to lay out an X-shaped grass grid.

[0015] A paving machine based on the above-mentioned paving method includes an automatic material changing device, a forage conveying device, a trenching device, a drive device, a frame, and a PLC controller. The drive device is located on both sides of the frame and drives the movement of the drive device. The automatic material changing device completes the storage and replacement of forage rolls. The forage conveying device completes the conveying and cutting of forage. The trenching device presses the forage mat into the sand to complete the paving. The PLC controller controls the rotation of gears in the mechanism.

[0016] Furthermore, the turntable mechanism is located in the first-layer automatic material changing device. Six hay bales are stored evenly and symmetrically in the turntable. The turningtable is controlled by a motor to drive the main shaft of the material changing device to rotate the rollers on the turntable along the track, so that the hay bales are transported to the designated position.

[0017] Furthermore, the stationary disc is located below the turntable and supports the turntable mechanism; the lifting mechanism is driven by a three-motor system to transport the hay rolls from the first layer to the designated position on the second layer, and can also return the used hay rolls to their original position, with the turntable completing the rotation and material replacement.

[0018] Furthermore, the forage conveying device includes a feeding mechanism and a cutting and dispensing mechanism. The feeding mechanism is driven by a motor and unfolds the straw curtain transported to the second layer through a transmission gear and transmission shaft. After moving along the straw curtain through the through groove to the end of the through groove, the infrared obstacle sensor located at the end of the through groove is triggered.

[0019] Furthermore, the cutting and dispensing mechanism includes a cutting mechanism and a dispensing mechanism. In the cutting mechanism, the cutting worm cuts the straw mat longitudinally into a suitable V-shape along a predetermined track. The V-shaped straw mats on both sides form an X-shaped straw mat. The dispensing device includes V-shaped sliders on both sides that reciprocate along the slider rails on both sides. The V-shaped sliders are longitudinally arranged and fixed on the third layer of the frame.

[0020] Furthermore, the trenching device includes a trenching mechanism and sand shovels. The trenching mechanism includes an intermittent incomplete gear mechanism driven by a motor. One rotation of the incomplete gear mechanism drives a crank-slider mechanism. The sand shovels include X-shaped sand shovels connected to a rotating rod, allowing for lateral and longitudinal movement. The incomplete gear mechanism drives the lower slider to move laterally, while the V-shaped sand shovels on both sides complete the second step of trenching. Then, the straw mat falls into the X-shaped track. A return spring moves back, and the rotating rod, connected to the X-shaped sand shovel, can return to its original position.

[0021] The advantages of this invention over existing technologies are:

[0022] 1. This invention can carry multiple straw mat rollers at once. After a pair of straw mats has been transported and used up, the material changing mechanism can automatically replace the used straw mat rollers with brand new straw mat rollers, reducing manual intervention.

[0023] 2. This invention, by connecting the first and last ends of the laid X-shaped straw mats, differs from the traditional single-grid laying method. It can complete the laying of straw squares over a large area and effectively solves the problem of difficulty in combining the horizontal and vertical directions in single-grid laying.

[0024] 3. The device of the present invention realizes the automatic laying process of X-shaped trajectory grass grid planting, which not only improves the laying efficiency and quality of grass grid, but also saves the space of the laying vehicle and increases the laying speed by using the longitudinal transport grass curtain roller.

[0025] 4. The device of this invention can be widely used for planting grass checkerboards in desert areas, benefiting a wide range of people. Attached Figure Description

[0038] The controller is connected to the automatic material changing device, the forage conveying device, the trenching device, and the drive device. The controller is a programmable PLC controller that controls the forward, backward, and stop movements of the laying device, the forage conveying device's forage conveying, changing, and cutting, and the trenching device's forage conveying and pressing.

[0039] like Figure 1 An automatic X-shaped grass checkerboard laying machine according to an embodiment of the present invention is shown. For ease of explanation, the accompanying drawings only show structures relevant to the embodiment.

[0040] Example 1

[0041] like Figure 1 The X-shaped grass checkerboard automatic laying machine 10 in a preferred embodiment of the present invention includes an automatic material changing device, a grass conveying device, a trenching device, a drive device, a frame 500, and a PLC controller 600.

[0042] The automatic feed changer has a feed roller replacement function. The feed roller replacement principle of the automatic feed changer is to replace the feed roller as the turntable rotates. The automatic feed changer has six feed rollers 110 spaced apart along a plane perpendicular to the first direction 20, a turntable mechanism 120, two lifting holes symmetrically arranged on the left and right, and a lifting mechanism 140 controlled by a motor 130.

[0043] The forage conveying device is installed at the bottom of the automatic material changing device, located in the middle layer of the entire vehicle body, and is used to transport the forage to the designated location after the material changing device completes the material changing. After the turntable mechanism 120 of the automatic material changing device completes the material changing, the forage conveying device can unfold the newly replaced forage roll and transport it to the forage trough of the second layer clamp, so that the ditching device can complete the ditching work and realize the forage laying work.

[0044] The ditching device is installed below the forage conveying device, located at the bottom of the entire vehicle body. It is used to grab the forage from the forage conveying device along the 211 forage curtain channel and put it into the cutting and dispensing mechanism. The cutting and dispensing mechanism then puts the forage into the sand ditch opened by the ditching device. The sand shovel 340 can be composed of two symmetrical V-shaped double-layer sand shovels. After being inserted into the sand, it is driven by the ditching transmission device 330 to complete the lateral wide sand ditching movement of V-shaped sand shovel one and V-shaped sand shovel two, realizing the deep cultivation of forage.

[0045] The drive unit includes a tracked walking mechanism 410 enclosing each drive wheel, a sixth motor 420, and a seventh motor 430. The tracked walking mechanism 410 includes tracks 411, a drive wheel 412, a driven wheel 413, and a shock-absorbing link 414. The drive unit is mounted on both sides of the vehicle body and uses motors to independently drive each track wheel, enabling the vehicle body to move in a fixed direction. Therefore, when the X-shaped grass checkerboard automatic laying machine is on a horizontal plane, both the first direction 20 and the second direction 30 are horizontal. If the first direction 20 is the front-to-back direction of the vehicle body 10, then the second direction 30 is the left-to-right direction of the vehicle body 10.

[0046] When the X-shaped straw checkerboard automatic laying machine 10 is on a horizontal plane, the lifting mechanism 140 drives the straw roll structure 110 to rise and fall in the vertical plane along the lifting hole. The lifting mechanism 140 can be a lifting toothed plate and fixed gear, a scissor-type lifting mechanism, a drive cylinder, a lifting mechanism, or other types of structures, as long as it can drive the straw roll structure 110 to rise and fall in the vertical plane.

[0047] To facilitate understanding, the working process of the X-shaped grass checkerboard automatic laying machine 10 described above is briefly explained below:

[0048] (1) Start the X-shaped grass grid automatic laying machine 10 so that the entire X-shaped grass grid automatic laying machine 10 can travel along the preset route;

[0049] (2) During the movement of the X-shaped grass grid automatic laying machine 10, the trenching transmission mechanism 330 will drive the trenching mechanism 310 to drive the sand shovel 340 to insert into the sand. The V-shaped sand shovel one and V-shaped sand shovel two will move laterally in opposite directions to dig the sand on the ground to the left and right sides along the X-shaped sand shovel slide rail 344, forming a trench on the ground.

[0050] (3) While performing the above steps (1) and (2), the hay conveying device will transfer the hay rolls sent by the lifting mechanism 140 to the bottom plate hay curtain channel 211 in sequence;

[0051] (4) The lifting mechanism 140 drives the ditching device to rise and fall in the vertical plane. When the X-shaped sand shovel slide rail 344 passes under the grass curtain channel 211, it can accurately catch and hold the grass material falling from the gap. When the sand shovel 340 is driven by the ditching transmission mechanism 330 to insert into the sand, it directly inserts into the sand. Under the drive of the ditching mechanism 310 component, the ditch is opened and the sand is widened. The X-shaped sand shovel slide rail 344 device is released and the grass square is accurately placed into the ditch.

[0052] (5) The sand on both sides of the trench is loosened by the action of the sand shovel 340 and flows back into the trench to fix the grass blocks in the trench and improve the stability of the grass blocks after laying.

[0053] By using the forage conveying device, lifting mechanism 140 and trenching device, the forage roll at the loading station 110 can be unfolded and moved to the top of the newly opened trench for precise placement. This reduces the placement height of the forage blocks, thereby reducing the probability of the placement position deviating from the trench due to the light weight of the programmed forage blocks. This is beneficial for quantitative and uniform laying of forage blocks.

[0054] Example 2

[0055] The fodder conveying device can also convey the fodder rolls from the feeding station 110 to the sand trench opened by the trenching device in sequence and evenly. When the sand shovel 340 digs the trench, it puts the fodder into the trench. At this time, some of the sand on both sides of the trench flows back into the trench under its own gravity when the trenching action is completed, so as to fix the fodder blocks in the trench and improve the firmness of the fodder blocks after laying.

[0056] like Figure 3 In some embodiments, the material changing device consists of a turntable mechanism 120 and a lifting mechanism 140 working together. Each part is driven by a motor and works in conjunction with each transmission shaft to transport the straw rolls 110 to the feeding station, ensuring the continuity of the laid straw grid. The material changing turntable 120 includes six evenly distributed straw rollers 110. Two circular holes of the same size as the straw rollers are symmetrically arranged on the left and right sides of the bottom of the turntable. These holes are used by the lifting mechanism to transport the straw rollers from the feeding station 110 to the straw transport device. Whenever the target straw roller is used up, the turntable is driven by the motor to rotate and replace the straw, thereby further improving the laying efficiency of the above-mentioned X-type straw grid automatic laying machine 10.

[0057] like Figure 4 In some embodiments, the lifting mechanism 140 is mainly controlled by a motor. The transmission shaft 145 moves in coordination with the sprocket 147, the sprocket 148 and the chain 149. The power is transmitted to the gear 141 through the transmission shaft 146. The gear 141 reciprocates along the lifting main shaft 144 to achieve the lifting function.

[0058] After the turntable rotates and grabs the grass roller above the lifting hole, the lifting mechanism transports the brand-new grass roller from loading station 110 to the second layer of the vehicle body. The lifting toothed plate reciprocates along the outer circumference of the fixed gear, and the opposing movement drives the toothed plate to achieve up-and-down reciprocating motion. After the grass roller reaches the second layer of the vehicle body, the roller brushes on the second layer work together to unfold the outer edge of the grass roller, conveying the grass to the corresponding position.

[0059] like Figure 5The device uses gears and racks for transmission. After the hay roll is transported to the hay conveying device, the hay is transported to the top of the hay channel 211 by the coordinated movement between the rubber rollers 212 and the feeding transmission mechanism 230. The hay is arranged along the channel, and then the cutting transmission mechanism 260 controls the cutting and feeding mechanism to cut the hay roll, completing the continuous conveying and cutting of hay. This process is carried out continuously, which further improves the laying efficiency of hay blocks.

[0060] like Figure 7 In Embodiment 2, the cutting transmission mechanism 260 is mainly controlled by the drive gear 261 moving along the drive shaft 262, which in turn controls the driven gear 263 to drive the sprocket 264. After the infrared obstacle sensor 1 241 and the infrared obstacle sensor 242 detect the grass, the corresponding V-shaped slider moves along the slider rail 245, driving the connecting rod 246, which in turn pushes the turbine 247 and the cutting worm gear 248 to cut the grass. The cut grass falls through the gaps in the grass channel into the X-shaped sand shovel rail, and is then laid by the sand shovel opening trenches.

[0061] like Figure 8 In Embodiment 2, the trenching device is mainly driven by a motor-driven trenching transmission mechanism 330, which in turn drives the trenching mechanism 310 to move, thereby driving the sand shovel 340 to achieve trenching. The trenching transmission mechanism transmits power from the motor to the driven shaft 334 via the transmission main shaft 331, which is then driven by the transmission gear 332 and driven gear 333. The driven shaft 334 drives the incomplete gear 335 and the complete gear 336 to transmit power to the crank connecting rod of the trenching mechanism, which pushes the slide block to move. This, in turn, pushes the sand shovel to move laterally along the sand shovel slide rail after it is inserted into the sand, thus achieving trenching.

[0062] Since the drive mechanism 330 is a gear transmission structure, it has the advantages of high transmission accuracy and efficiency, long service life, stable operation and high reliability. Therefore, setting the drive component 331 as the first rotating shaft, planetary mechanism 333 and first drive component 330 can improve the running accuracy and working stability of the target component and extend the service life of the component, so as to further improve the laying effect and reliability of the above-mentioned X-type grass grid automatic laying machine 10.

[0063] Example 3

[0064] like Figure 7 In Embodiment 3, the forage cutting device includes two symmetrically arranged cutters. These cutters are driven by a crank mechanism 246 to move along the outer edge of a turbine 247 within a cutting groove. This, in conjunction with the second-layer forage conveying device, cuts the forage mat upon reaching a designated position, preventing any sticking. The forage is caught by a forage tray brought up by a lifting mechanism through free-fall motion, and then the aforementioned components complete the forage grid laying. This further improves the laying effect and reliability of the aforementioned X-type forage grid automatic laying machine 10.

[0065] like Figure 5 In the above embodiment, the second layer of the grass conveying device is mainly composed of 8 roller brushes. The rotation of the central shaft drives the roller brushes to rotate. The 8 roller brushes are arranged in specific positions and roll along the outer edge of the grass roller to transport the grass along the chassis guide groove to the designated position. Then, the grass inserting plate grabs the grass into the grass trough to realize the grass grabbing and laying.

[0066] The following explanation addresses the meanings of some terms in the above embodiments: the round hole in the base plate refers to the round hole through which the lifting mechanism 140 moves up and down, and this hole is symmetrically arranged about the center of the vehicle body.

[0067] like Figure 1 In Embodiment 3, the vehicle body 10 includes two drive units and is respectively disposed on both sides of the vehicle body. Specifically, each drive unit includes at least four traveling wheels 412 spaced apart along the first direction 20. The traveling wheels are connected by connecting rods, and each of the aforementioned traveling wheels is controlled by a motor. Each traveling wheel is surrounded by a track 411. This improves the stability of the paving vehicle and further enhances the paving effect of the grass blocks.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
