Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a sowing device for ecological restoration of desertified grasslands. Background Art

[0002] Desertified grassland refers to the phenomenon of reduced grassland vegetation, exposed soil and decreased land productivity due to natural factors (such as climate change and soil erosion) and human factors (such as overgrazing and unreasonable reclamation). Desertified grassland not only affects the local ecological environment, but also has a profound impact on surrounding areas and even the entire ecosystem. The ecological restoration of desertified grassland requires long-term investment and continuous management, but financial and technical support are often limited; at the same time, the impact of climate change and human activities on desertified grassland is also increasing. Therefore, in the future, it is necessary to further strengthen the research and practice of ecological restoration of desertified grassland and explore more efficient and sustainable restoration methods and technologies.

[0003] In the prior art, such as patent publication number: CN106612769A, a seeder and a sowing device are provided. The seeder includes: a shell, a feed portion and a discharge portion arranged in the shell, wherein a feed chamber, a first screening chamber, and a second screening chamber are arranged in the shell; the discharge portion is provided with a first discharge port, a second discharge port, and a third discharge port which are connected to the feed chamber, the first screening chamber, and the second screening chamber in sequence; a primary sieve plate and a secondary sieve plate arranged obliquely in the shell; a blower and a vacuum cleaner located in the feed chamber; a sowing pipe selectively connected to the first discharge port, the second discharge port, and the third discharge port; and a nozzle including a fixed shovel and a movable shovel arranged at the outlet end of the sowing pipe. The seeder can simultaneously achieve seed removal, screening, and selective sowing. The sowing device includes the seeder and a sprinkler connected to the seeder. The sowing device has multiple functions and a scientific design.

[0004] Although the above patented device can maintain the diversity of the device during the sowing process, the patent still has many limitations when used;

[0005] First, uneven ground significantly impacts seed drill operations, especially on desertified grasslands. This unevenness causes fluctuations in the depth at which the seeder's furrow opener cuts into the soil, directly affecting the seeding depth. If the sowing depth is too shallow, the seeds face greater risks, such as being blown away by the wind or failing to germinate in drought conditions. Conversely, if the sowing depth is too deep, it may make it difficult for the seeds to break through the soil, reducing germination and emergence rates.

[0006] In addition, uneven ground will also have an adverse effect on the row spacing control of the seeder. On desertified grasslands, due to the strong fluidity of the soil, the uneven ground is more likely to cause the seeder to deviate during driving, thereby further aggravating the unevenness of the row spacing. The uneven row spacing will not only affect the growth space and light conditions of the crops, but may also have a negative impact on the yield and quality of the crops. Summary of the Invention

[0007] The purpose of the present invention is to provide a sowing device for ecological restoration of desertified grasslands to solve the problems raised in the above background.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: a sowing device for ecological restoration of desertified grassland, comprising:

[0009] The main sowing mechanism is used to connect the entire equipment. When in use, the crushing roller at the bottom crushes and cleans the impurities on the path. Then the smoothing roller rotates and generates rolling friction with the ground to achieve smoothing of the road surface.

[0010] The wheel mechanism, which acts during the formation process, relies on the flexible tire connecting piece connecting each two annular tire bodies as a force point and is in contact with the road surface. The gravity of the equipment creates pressure on the force point, and ultimately acts on the pressure sensor. The pressure generated on the wheel mechanism when driving on a flat road and on a slope is different. The greater the slope, the greater the pressure detected by the pressure sensor.

[0011] The adjusting mechanism is used to adjust the bottom opening device and the soil depth through the cooperation of its various components;

[0012] The driving mechanism is used to drive the entire device to move by relying on the power generated by itself.

[0013] Preferably, the wheel mechanism includes two bearing seats;

[0014] A driving rod is fixedly inserted between the inner surface walls of the two bearing seats, and the outer surface wall fixing sleeve of the driving rod is provided with two inner disks. The outer surface wall of the driving rod is fixedly connected to two sets of dust covers, and the outer surfaces of the two inner disks are fixedly connected to a set of fixing seats. The interiors of the two sets of fixing seats are preset with movable holes, and the inner surface walls of the two sets of movable holes are rotatably connected to the inner rods. The outer surface wall fixing sleeves of the two sets of inner rods are provided with two spring return actuators, and the bottoms of the two sets of spring return actuators are fixedly connected to the bottom of the inner wall of the fixing seat. The outer surfaces of the two sets of inner rods are fixedly provided with two spring return actuators. The surface walls are fixedly sleeved with mounting seats, and the tops of the two groups of mounting seats are fixedly connected with annular tire bodies. A flexible tire connecting piece is fixedly connected between each two of the two groups of annular tire bodies. The two wheel body mechanisms keep rolling on the desertified grass. When the two wheel body mechanisms rotate at the same frequency, their respective maximum force deformation points are concentrated at the position of the flexible tire connecting piece. This connecting piece will be squeezed inward when subjected to force. At the same time, the mounting seat will tilt to one side along the outer wall of the inner rod. As the mounting seat tilts, the top annular tire body also The device tilts accordingly. During this process, the distance between the two adjustment seats and the short rods fixed inside them, which serve as fixed reference points, shortens. This shortening of the distance creates a squeezing effect on the detection assembly, and in turn, on the pressure sensor. Through this squeezing, the pressure sensor can detect the pressure value when the device is traveling on desertified grassland. The pressure values ​​experienced by the device will vary on different sections of desertified grassland, such as flat sections, inclined sections, and downhill sections. When traveling on flat desertified grassland, the gravity of the device mainly acts in the vertical direction of the two wheel mechanisms. At this time, the pressure experienced by the wheel mechanisms is relatively uniform and stable. However, when the device travels on a slope, the pressure experienced by the wheel mechanisms varies due to the shift in the center of gravity and the change in the contact area between the wheel mechanisms and the road surface. Specifically, the wheel mechanisms located on the uphill side will experience greater pressure, while the wheel mechanisms located on the downhill side will experience less pressure. In this way, the device can effectively detect and process pressure values ​​on different sections of road, providing accurate data support for subsequent sowing or other operations.

[0015] Preferably, an adjustment seat is fixedly connected between the two groups of fixing seats and the outer wall of the annular tire body, a short rod is fixedly inserted into the interior of the two groups of adjusting seats, and a detection component is movably sleeved between the outer walls of the two groups of short rods;

[0016] The detection components each include two adjusting rods, one side of the outer wall of one of the two adjusting rods is fixedly connected to an extension rod, the outer walls of the two extension rods are fixedly connected to an embedding block, one side of the outer wall of the other of the two adjusting rods is provided with an embedding groove, and the extension rod and the outer wall of the embedding block are slidably embedded in the inside of the embedding groove, thereby maintaining the two adjusting rods during the embedding movement with respect to each other and effectively limiting their embedding movement.

[0017] Preferably, a pressure sensor is fixedly connected between one side of the outer wall of the two extension rods and one side of the inner wall of the embedding groove, and a spring body is interactively sleeved on the outer wall of the pressure sensor. The function of the spring body is to achieve effective reset processing of the two adjustment rods.

[0018] Preferably, the adjustment mechanism includes a crossbeam plate;

[0019] The outer wall of the crossbeam plate is fixedly connected to a group of U-shaped mounting brackets by screws, the top of a group of the U-shaped mounting brackets is fixedly connected to a reciprocating motor, the adjusting ends of a group of the reciprocating motors are fixedly connected to two telescopic adjusting plates, one side of the outer wall of a group of the crossbeam plates is fixedly connected to a limited outer frame plate, the interior of a group of the limited outer frame plates is preset with an embedded plate, the interior of a group of the embedded plates is fixedly inserted with a built-in rod, and the outer wall of a group of built-in rods is movably inserted into the interior of each group of telescopic adjusting plates. In order to achieve precise adjustment of the height of the opener, the telescopic ends of multiple groups of telescopic adjusting plates are movably connected to the built-in rods, ensuring that when the reciprocating motor rotates downward, it can stably drive the embedded plate to move downward, and it can adjust its own length to meet the needs of such adjustment.

[0020] Preferably, a group of the U-shaped mounting frames are fixedly connected to one side of the outer wall, a group of the side panels are provided with movable grooves inside, a group of the inner surface walls of the movable grooves are movably embedded with movable rods, and an opener is fixedly connected between a group of embedded plates and a group of movable rods at the bottom. When the reciprocating motor rotates downward, the embedded plate is driven to move downward. The embedded plate is movably embedded in the interior of the limiting outer frame plate and the movable rod is movably embedded in the movable groove under the double limit. Through this embedded movement method, the height of the opener fixed between the movable rod and the bottom of the embedded plate is adjusted, thereby adjusting the opening depth for sowing in desertified grassland.

[0021] Preferably, the driving mechanism includes a driving motor, the rotating end of the driving motor is fixedly connected to a driving gear, the outer wall of the driving gear is meshed with a driven gear, one side of the outer wall of the driven gear is fixedly connected to a linkage gear, and one side of the outer wall of the linkage gear is fixedly connected to one side of the outer wall of the smoothing roller. When the driving motor is powered on, its output end drives the driving gear to rotate, the driving gear meshes with the driven gear for transmission, and the linkage gear is fixedly installed on the other side of the driven gear, and the three maintain linkage.

[0022] Preferably, the outer wall of the linkage gear is meshed with a chain, the inner wall of the chain is meshed with an internal gear, and the outer wall of the driving rod is fixedly inserted into the inside of the internal gear, and a smoothing roller is fixedly installed on one side of the outer wall of the linkage gear. When the linkage gear rotates, the smoothing roller keeps rotating and generates rolling friction with the ground, which is used to smooth sandy grass. At its front end, a chain connects the linkage gear and the internal gear, and drives the driving rod to rotate through the internal gear, realizing rolling friction between the two wheel mechanisms and the road surface, thereby driving the entire equipment to move.

[0023] Preferably, the sowing main body mechanism includes a large bottom frame body, and one side of the outer wall of the driving motor is fixedly connected to one side of the outer wall of the large bottom frame body, and one side of the outer wall of the two bearing seats is fixedly connected to one side of the outer wall of the large bottom frame body, and two bearing frames are fixedly inserted inside the large bottom frame body, and a transmission rod is fixedly inserted between the inner walls of the two bearing frames, and a crushing roller is fixedly sleeved on the outer wall of the transmission rod, and two inner supporting plates are fixedly connected to the inner wall of the large bottom frame body, and a smoothing roller is rotatably connected between the insides of the two inner supporting plates. The external motor drives the transmission rod to rotate in the two bearing frames, and the transmission rod is fixedly connected to the crushing roller to maintain the linkage of rotation. When the crushing roller rotates, impurities on the ground are crushed and crushed. Subsequently, the smoothing roller contacts the ground and generates rolling friction to level the crushed and cleaned desertified grassland.

[0024] Preferably, the top of the large bottom frame body is fixedly connected to a top mounting bracket, and the outer wall of the crossbeam plate is fixedly connected to the inner wall of the large bottom frame body, the interior of the top mounting bracket is fixedly connected to two rotating seats, and a rotating rod is rotatably connected between the interiors of the two rotating seats, and the interiors of the top mounting bracket are fixedly connected to a storage box, and the bottoms of the storage boxes are fixedly connected to multiple backflow boxes, and a group of holes are preset in the interiors of the multiple backflow boxes, and the rotating rod movably passes through the interiors of the multiple groups of holes, and the outer wall of the rotating rod is fixedly sleeved with multiple seed diversion plates, and the bottoms of the multiple backflow boxes are fixedly connected to guide pipes, and the output ends of the multiple guide pipes are arranged in multiple openings. Inside the mouthparts, the seeds are stored upside down in the storage box, and under the natural action of gravity, the seeds fall into multiple backflow boxes respectively, and then the external motor is started, which drives the rotating rod to rotate stably inside the two rotating seats. Since the rotating rod and multiple seed diverter discs are fixedly installed, the rotating action of the rotating rod can drive each seed diverter disc to rotate inside the corresponding backflow box. During the rotation of the seed diverter disc, any stuck seeds will be effectively transferred backwards. This transfer process is continuous and uniform until the seeds are sent into the guide tube. The guide tube serves as a seed conveying medium, ensuring that the seeds can be continuously and stably conveyed to the inside of the bottom opener.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. In the present invention, first, when the equipment is in use, the two wheel bodies are used to roll while the internal pressure sensors monitor the changes in the pressure values ​​of the equipment on different sections of the road in real time, providing accurate data support for the adjustment of the sowing depth. The automation system generates corresponding control instructions based on the detection results, and realizes the precise adjustment of the height of the opener through the cooperation of multiple sets of telescopic adjustment plates and reciprocating motors. This processing method adjusts the depth of the sowing opening based on the detected slope, ensuring the planting effect of seeds on terrains with different slopes.

[0027] 2. In the present invention, when the equipment is in use, the driving motor drives the smoothing roller to rotate, generating rolling friction with the ground, effectively smoothing the sandy grassland, and the front end crushing roller crushes and rolls the impurities on the ground during the movement, further improving the flatness of the ground and providing a good road surface environment for sandy grassland for subsequent seed planting.

[0028] 3. In the present invention, the seeds are stored upside down inside the storage box, which provides sufficient preliminary preparation for sowing. Under the action of gravity, the seeds automatically fall into multiple backflow boxes, providing an orderly seed flow for the subsequent sowing process. Then the external motor drives the rotating rod to rotate, driving the seed diversion plate to rotate in the backflow box, effectively avoiding the phenomenon of seed jamming. When the seeds are continuously transported to the bottom opener through the guide tube, the continuity and uniformity of sowing are ensured, and the planting efficiency is improved.

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0042] Example 1, refer to Figures 1-11 As shown: The present invention provides a sowing device for ecological restoration of desertified grassland, comprising:

[0043] The sowing main body mechanism 1 is used to connect the entire equipment. When in use, the crushing roller 113 at the bottom completes the crushing and cleaning of impurities on the travel path, and then the smoothing roller 121 rotates and generates rolling friction with the ground to achieve the leveling of the road surface;

[0044] The wheel mechanism 2 acts during the forming process, relying on the flexible tire connecting piece 241 connecting each two annular tire bodies 24 to each other as a force point and in contact with the road surface. The gravity of the equipment creates pressure on the force point, and ultimately acts on the pressure sensor 266. The pressure generated on the wheel mechanism 2 when driving on a flat road and on a slope is different. The greater the slope, the greater the pressure detected by the pressure sensor 266.

[0045] The adjusting mechanism 3 is used to adjust the bottom opening device 39 and the soil depth through the cooperation of its various components;

[0046] The driving mechanism 4 is used to drive the entire device to move by relying on the power generated by itself.

[0047] In this embodiment, the control command is transmitted to the inside of the controller, and the controller simultaneously starts multiple reciprocating motors 33, whose output ends begin to rotate and move up or down, and uses multiple sets of telescopic adjustment plates 331 as transmission media, and has its own elasticity to meet the use requirements, and the telescopic ends of the multiple sets of telescopic adjustment plates 331 are in a state of active connection with the built-in rods 351. When the reciprocating motor 33 rotates downward, it can drive the embedded plate 35 to move downward, and the embedded plate 35 is movably embedded in the inside of the limiting outer frame plate 34, and the movable rod 38 is movably embedded in the inside of the movable groove 371. In this way, the height of the opener 39 fixed between the movable rod 38 and the bottom of the embedded plate 35 can be adjusted, thereby adjusting the depth of the opening for sowing in the desertified grassland;

[0048] Moreover, with this processing method, the greater the slope to be detected, the greater the opening required for sowing.

[0049] Example 2, according to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 as well as Figure 8 As shown, the sowing main body mechanism 1 includes a large bottom frame body 11, and one side of the outer wall of the two bearing seats 21 is fixedly connected to one side of the outer wall of the large bottom frame body 11, and two bearing frames 111 are fixedly inserted inside the large bottom frame body 11, and a transmission rod 112 is fixedly inserted between the inner surface walls of the two bearing frames 111, and a crushing roller 113 is fixedly sleeved on the outer surface wall of the transmission rod 112.

[0050] The wheel body mechanism 2 includes two bearing seats 21;

[0051] A driving rod 211 is fixedly inserted between the inner surface walls of the two bearing seats 21, and two inner disks 22 are fixedly sleeved on the outer surface wall of the driving rod 211. Two sets of dust covers 221 are fixedly connected to the outer surface wall of the driving rod 211. The outer surfaces of the two inner disks 22 are fixedly connected to a set of fixing seats 23. The interiors of the two sets of fixing seats 23 are preset with movable holes 231. The inner surface walls of the two sets of movable holes 231 are rotatably connected to the inner rods 232. The outer surface walls of the two sets of inner rods 232 are fixedly sleeved with two spring return actuators 233, and the two sets of spring return actuators 233 are fixedly sleeved. The bottoms are fixedly connected to the bottom of the inner wall of the fixing seat 23, the outer walls of the two groups of inner rods 232 are fixedly sleeved with mounting seats 234, the tops of the two groups of mounting seats 234 are fixedly connected to the annular tire body 24, and a flexible tire connecting piece 241 is fixedly connected between each two of the two groups of annular tire bodies 24. An adjustment seat 25 is fixedly connected between the two groups of fixing seats 23 and the outer walls of the annular tire body 24, and a short rod 251 is fixedly inserted into the interior of the two groups of adjustment seats 25. A detection component 26 is movably sleeved between the outer walls of the two groups of short rods 251;

[0052] Each detection assembly 26 includes two adjustment rods 261, one of which is fixedly connected to an extension rod 262 on its outer wall, and an embedding block 263 on its outer wall. An embedding groove 264 is formed on the outer wall of the other of the two adjustment rods 261, and the outer walls of the extension rods 262 and the embedding block 263 are slidably embedded in the embedding groove 264. A pressure sensor 266 is fixedly connected between the outer wall of the two extension rods 262 and the inner wall of the embedding groove 264. The outer wall of the pressure sensor 266 is interactively sleeved with a spring body 265.

[0053] The adjustment mechanism 3 includes a crossbeam plate 31;

[0054] The outer wall of the crossbeam 31 is fixedly connected to a group of U-shaped mounting brackets 32 by screws, the top of a group of U-shaped mounting brackets 32 are fixedly connected to a reciprocating motor 33, the adjustment end of a group of reciprocating motors 33 are fixedly connected to two telescopic adjustment plates 331, one side of the outer wall of a group of crossbeam plates 31 are fixedly connected to a limited outer frame plate 34, the interior of a group of limited outer frame plates 34 are preset with embedded plates 35, the interior of a group of embedded plates 35 are fixedly inserted with built-in rods 351, and the outer wall of a group of built-in rods 351 are movably inserted in Inside each set of telescopic adjustment plates 331, a side plate 37 is fixedly connected to one side of the outer wall of a set of U-shaped mounting frames 32, a movable groove 371 is opened inside a set of side plates 37, and a movable rod 38 is movably embedded in the inner wall of a set of movable grooves 371. An opener 39 is fixedly connected between the bottom of a set of embedded plates 35 and a set of movable rods 38, and the outer wall of the crossbeam plate 31 is fixedly connected to the inner wall of the large bottom frame body 11, and the output ends of multiple guide tubes 153 are all arranged inside the multiple openers 39.

[0055] In this embodiment, when the device is in use, it is driven by an external driving device to move the device. During the movement, the transmission rod 112 is driven by the external motor to rotate inside the two bearing frames 111. The transmission rod 112 and the crushing roller 113 are in a fixed connection state, and the rotation linkage between the two is maintained. During the rotation of the crushing roller 113, impurities (stones, wood piles, etc.) on the ground can be crushed and crushed. During the backward movement, the smoothing roller 121 is in contact with the ground and generates rolling friction, which can level the crushed and cleaned desertified grassland, thereby maintaining the flatness of the ground.

[0056] Then, when the device moves backward, the two wheel mechanisms 2 remain in a rolling state with the desertified grassland. Figure 10For example, when the two wheel mechanisms 2 rotate at the same frequency, the maximum force deformation point of each wheel mechanism 2 is at the position of the flexible tire connecting piece 241, and the flexible tire connecting piece 241 will be squeezed inward, and the mounting seat 234 will tilt to one side on the outer wall of the inner rod 232, and the top annular tire body 24 will tilt in conjunction with the tilt of the mounting seat 234. During this tilting process, the two adjustment seats 25 and the short rod 251 fixedly inserted therein serve as fixed points, which will shorten the distance between the two adjustment seats 25. In this process, a squeezing process is formed on the detection component 26. When the detection component 26 is squeezed, first, the extension rod 262 and the embedding block 263 provided on one side of the outer wall of the two adjustment rods 261 will be movably embedded in the embedding groove 264, thereby forming a squeezing process on the pressure sensor 266. During this squeezing process, the pressure value of the device when it is traveling on the desertified grassland is detected. During this detection process, the pressure values ​​on the flat road section, inclined road slope, and downhill section of the desertified grassland are different.

[0057] First, when the vehicle is traveling on flat sandy grassland, the gravity of the device mainly acts on the two wheel mechanisms 2 in the vertical direction, and the pressure on the wheel mechanisms 2 is relatively uniform and stable. When the two wheel mechanisms 2 are traveling on a slope, the pressure on the wheel mechanisms 2 will change due to the shift of the center of gravity of the device and the change in the contact area between the wheel mechanisms 2 and the road surface. Therefore, the tire located on the uphill direction will be subject to greater pressure; conversely, the wheel mechanism 2 located on the downhill direction will be subject to less pressure. Relying on this method, the device can effectively complete the effective detection and processing formed on different road sections.

[0058] Moreover, this type of detection uses one rotation of each wheel mechanism 2 as the detection frequency band, and the signal detected by the internal pressure sensor 266 is converted into an electrical signal and transmitted to the analysis system through the internal wire group. The computer program will process, filter and judge the perceived data according to pre-set rules and logic, and generate corresponding feedback. According to the analysis results, the automation system will generate corresponding control instructions.

[0059] Example 3, according to Figure 1 、 Figure 2 、 Figure 9 as well as Figure 10As shown, the sowing main body mechanism 1 includes a large bottom frame body 11, and one side of the outer wall of the driving motor 41 is fixedly connected to one side of the outer wall of the large bottom frame body 11, and one side of the outer wall of the two bearing seats 21 is fixedly connected to one side of the outer wall of the large bottom frame body 11. Two bearing frames 111 are fixedly inserted into the interior of the large bottom frame body 11, and a transmission rod 112 is fixedly inserted between the inner surface walls of the two bearing frames 111.

Two inner receiving plates 12 are fixedly connected to the inner surface wall of the large bottom frame body 11, and a smoothing roller 121 is rotatably connected between the insides of the two inner receiving plates 12. The top of the large bottom frame body 11 The top is fixedly connected to a top mounting frame 13, the interior of the top mounting frame 13 is fixedly connected to two rotating seats 131, the interior of the two rotating seats 131 is rotatably connected with a rotating rod 14, the interior of the top mounting frame 13 is fixedly connected to a storage box 15, the bottom of the storage box 15 is fixedly connected to a plurality of backflow boxes 151, the interior of the plurality of backflow boxes 151 is preset with a group of holes 152, and the rotating rod 14 movably runs through the interior of the plurality of groups of holes 152, the outer wall of the rotating rod 14 is fixedly sleeved with a plurality of seed diverter plates 141, the bottoms of the plurality of backflow boxes 151 are fixedly connected to guide pipes 153, and the output ends of the plurality of guide pipes 153 are all arranged inside the plurality of openers 39;

[0060] The driving mechanism 4 includes a driving motor 41, the rotating end of the driving motor 41 is fixedly connected to a driving gear 411, the outer wall of the driving gear 411 is meshedly connected to a driven gear 42, one side of the outer wall of the driven gear 42 is fixedly connected to a linkage gear 43, and one side of the outer wall of the linkage gear 43 is fixedly connected to one side of the outer wall of the smoothing roller 121, the outer wall of the linkage gear 43 is meshedly transmitted with a chain 44, the inner wall of the chain 44 is meshedly transmitted with an internal gear 45, and the outer wall of the driving rod 211 is fixedly inserted into the inside of the internal gear 45.

[0061] In this embodiment, before the device is used, the seeds are first inverted inside the storage box 15 for preliminary storage, and then under the action of gravity, the seeds can be kept falling into the multiple backflow boxes 151 respectively, and then driven by the external motor, the rotating rod 14 is driven to rotate inside the two rotating seats 131, and because the rotating rod 14 and the multiple seed diverter discs 141 are in a fixed installation state, the rotation of the rotating rod 14 can drive each seed diverter disc 141 to rotate respectively inside the backflow box 151, and during the rotation of the seed diverter disc 141, the stuck seeds can be transferred backwards and then transferred to the inside of the guide tube 153, and with it as a conveying medium, the seeds can be kept continuously and conveyed to the inside of the bottom opener 39;

[0062] At this time, when the driving motor 41 is powered on, its output end can drive the driving gear 411 to rotate, because the driving gear 411 and the driven gear 42 are in a state of meshing transmission, and the other side of the driven gear 42 is a fixedly installed linkage gear 43, thereby maintaining the linkage between the three, and one side of the outer wall of the linkage gear 43 is a fixedly installed smoothing roller 121, which can keep the sandy grass flat. Finally, the connection between the linkage gear 43 and the internal gear 45 is realized by the chain 44, and the driving rod 211 is also driven to rotate through the internal gear 45, thereby realizing the rolling friction between the two wheel mechanisms 2 and the road surface, driving the entire equipment to move.

[0063] The working principle of the entire mechanism is as follows: before using the device, the seeds are first stored upside down in the storage box 15 for preliminary storage, and under the action of gravity, the seeds will fall into multiple backflow boxes 151 respectively, providing preliminary preparation for subsequent use. Subsequently, the external motor is started to drive the rotating rod 14 to rotate inside the two rotating seats 131. Since the rotating rod 14 is fixedly installed with multiple seed diverter discs 141, the rotation of the rotating rod 14 will drive each seed diverter disc 141 to rotate in the backflow box 151, and transfer the stuck seeds backward to the guide tube 153, and then continuously transport them to the bottom opener 39. At the same time, when the driving motor 41 is powered on, its output end drives the driving gear 411 to rotate, and the driving gear 41 1 is meshed with the driven gear 42 for transmission, and a linkage gear 43 is fixedly installed on the other side of the driven gear 42, and the three maintain linkage. A smoothing roller 121 is fixedly installed on one side of the outer wall of the linkage gear 43, thereby keeping the smoothing roller 121 rotating and generating rolling friction with the ground to smooth the sandy grass. At its front end, a chain 44 connects the linkage gear 43 and the internal gear 45, and drives the driving rod 211 to rotate through the internal gear 45, thereby realizing the rolling friction between the two wheel body mechanisms 2 and the road surface, thereby driving the entire equipment to move. During the movement, the external motor drives the transmission rod 112 to rotate in the two bearing frames 111. The transmission rod 112 is fixedly connected to the crushing roller 113 to maintain the linkage of rotation. When the crushing roller 113 rotates, it crushes the impurities on the ground. The equipment is crushed and crushed, and then the smoothing roller 121 contacts the ground and generates rolling friction to level the crushed and cleaned desertified grassland. When the equipment moves backward, the two wheel mechanisms 2 maintain a rolling state with the desertified grassland. In the process of the wheel mechanism 2 rotating at the same frequency, the maximum force deformation point is located at the position of the flexible tire connecting piece 241. The flexible tire connecting piece 241 is squeezed inward, and the mounting seat 234 is tilted to one side on the outer wall of the inner rod 232. The top annular tire body 24 is tilted to one side in accordance with the inclination of the mounting seat 234. In this process, the two adjustment seats 25 and the short rods 251 fixed therein are used as fixed points to shorten the distance between each other, thereby forming an extrusion process for the detection component 26. When the detection component 26 is squeezed The extension rod 262 and the embedding block 263 are movably embedded in the embedding groove 264 to squeeze the pressure sensor 266. The pressure sensor 266 detects the pressure value of the device when it is traveling on the desertified grassland, and provides feedback based on the pressure value changes of different road sections (flat road sections, inclined road slopes, downhill sections). The detection frequency band is one circle traveled by each wheel body mechanism 2. The signal detected by the pressure sensor 266 is converted into an electrical signal and transmitted to the analysis system through the internal wire group. The computer program processes, filters and judges the data according to pre-set rules and logic, and generates corresponding feedback. According to the analysis results, the automation system generates corresponding control instructions and transmits them to the controller. The controller simultaneously starts multiple reciprocating motors 33, and its output end starts to rotate.And move up or down, multiple sets of telescopic adjustment plates 331 serve as transmission media, which are flexible to meet usage needs. The telescopic end of the telescopic adjustment plate 331 is movably connected to the built-in rod 351. When the reciprocating motor 33 rotates downward, it drives the embedded plate 35 to move downward. The embedded plate 35 is movably embedded in the interior of the limiting outer frame plate 34 and the movable rod 38 is movably embedded in the movable groove 371. Under the dual limit, through this embedded movement, the height of the opener 39 fixed between the movable rod 38 and the bottom of the embedded plate 35 is adjusted, thereby adjusting the opening depth for sowing in desertified grassland. This processing method relies on the detected slope to adjust the depth of the sowing opening. The greater the slope, the larger the required opening should be to ensure the sowing effect. The seeds entering the opener 39 will be buried in the soil under the subsequent soil cover, forming a planting process for the seeds.
