Description

Technical Field

[0001] This invention relates to the technical field of tree planting, and specifically discloses an arbuscular mycorrhizal fungi inoculation and automatic plant planting device. Background Technology

[0002] Arbuscular mycorrhizal fungi can establish mutually beneficial symbiotic relationships with over 85% of terrestrial plants, and their mycorrhizal structure can significantly enhance the plant's ability to absorb water, minerals, and other substances. Under stress conditions such as heavy metal pollution and drought, arbuscular mycorrhizal fungi can exert their unique advantages, thereby improving the plant's resistance. In plant cultivation, sowing is frequently required. However, due to complex terrain and significant topographical variations, large-scale mechanized sowing is often difficult, and manual sowing is still the primary method in these areas. Manual sowing is time-consuming, labor-intensive, and cannot achieve precise sowing, and it also causes significant lumbar strain for the operators. Arbuscular mycorrhizal fungi can improve soil structure and enhance the quality of plant growth and development, and can be used for simultaneous inoculation on top of automated sowing systems.

[0003] To address this issue, Chinese utility model patent (publication number: CN215011526U) discloses an arbuscular mycorrhizal fungi inoculation and plant sowing device, comprising a first long rod, a fixing block fixedly connected to the right side wall of the first long rod, a rotating shaft mounted on the fixing block, a second long rod fixedly connected to the side wall of the rotating shaft, and shovels fixedly connected to the lower ends of both the first and second long rods, with the two shovels arranged symmetrically to each other. A fan-shaped cavity is opened inside the fixing block, and the rotating shaft passes through the fan-shaped cavity. A metering box fixedly connected to the side wall of the rotating shaft is provided inside the fan-shaped cavity, and a feed hole communicating with the fan-shaped cavity is opened on the upper side wall of the fixing block.

[0004] While the above solution can automate the seeding process in plant cultivation, it is prone to problems when dealing with large quantities of seeds. Multiple seeds may become stuck at the dispensing port of the metering box, preventing continuous seeding. Furthermore, the seeding process requires manual counting by the operator, which is not only tedious but also prone to errors. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic planter for arbuscular mycorrhizal fungal inoculation, in order to solve the technical problem of seed blockage and simultaneous inoculation during the sowing process.

[0006] To achieve the above objectives, the basic solution of the present invention is as follows: an automatic plant planting device for arbuscular mycorrhizal fungi inoculation, comprising a cylinder and a support base, the support base being provided with a guide rod, the cylinder having a guide sleeve, the guide sleeve being slidably connected to the guide rod, and a discharge port being provided at the bottom of the cylinder.

[0007] The guide rod sidewall has a first rack along the axial direction; a counter is fixed on the outer wall of the cylinder, the counter has an output shaft, the counter is used to count the circumferential rotation of the output shaft, the output shaft is coaxially fixedly connected to a first gear and a vibrating wheel, the first gear meshes with the first rack, the vibrating wheel has a number of flexible pads arranged in an array on the circumferential outer wall, the flexible pads abut against the outer wall of the cylinder, and a striking block is fixed on the outer wall of the flexible pads.

[0008] The working principle of this basic solution is as follows: This technical solution utilizes a support base to bear the load of the entire planter. Furthermore, the guide sleeve of the cylinder is slidably connected to the guide rod of the support base, allowing the operator to slide the cylinder into the soil and use the discharge port at the bottom of the cylinder to achieve the technical effect of seed and inoculum dispensing.

[0009] As the cylinder slides relative to the guide rod, the first gear on the outer wall of the cylinder also rotates circumferentially due to its meshing with the first rack. The rotation of the first gear drives the output shaft to rotate circumferentially, and the rotation of the output shaft thus realizes the function of the counter technology. Ultimately, every time the operator presses down on the cylinder to add seeds and bacteria, the output shaft will rotate circumferentially once, and the counter will count once.

[0010] Furthermore, the rotation of the output shaft simultaneously drives the vibrating wheel to rotate circumferentially. The vibrating wheel utilizes a flexible pad abutting against the outer wall of the cylinder, achieving continuous intermittent contact with the outer wall during rotation. Each time the flexible pad contacts the cylinder, the striking block impacts the outer wall, ultimately achieving the technical effect of impact vibration on the cylinder.

[0011] The beneficial effects of this basic solution are as follows: 1. Compared with existing technologies, this technical solution can use the support base to achieve stable support for the entire device, effectively improving the stability of the device during the sowing process and avoiding tilting or displacement of the cylinder during the insertion of the cylinder into the soil.

[0012] Compared to existing technologies, this technical solution can achieve a counting function with a simple mechanical transmission structure each time the cylinder is inserted into the soil for sowing. The mechanical transmission structure not only facilitates stable operation and has a lower manufacturing cost compared to electrical instruments, but also has the technical advantage of being easy to maintain and replace.

[0013] Compared to existing technologies, this technical solution can also achieve the function of vibrating and striking the cylinder by utilizing the rotation of the vibrating wheel during the counting process, thereby achieving the technical effect of evenly distributing the seeds inside the cylinder.

[0014] Compared to existing technologies, this solution can utilize the same mechanical structure (axial rotation of the output shaft) to simultaneously achieve the functions of counting and vibrating the cylinder, greatly simplifying the composition of the device structure, optimizing the usable space of the device, effectively reducing the operating cost of the device, and has extremely high market application prospects.

[0015] Furthermore, the cylinder has a cylindrical structure, and a baffle is vertically fixedly connected inside the cylinder. The discharge port includes two outlets, which are respectively located on both sides of the baffle.

[0016] Beneficial effects: This technical solution, by adding a baffle inside the cylinder, divides the interior into two independent spaces, allowing the operator to choose freely according to the actual situation. The operator can simultaneously fill the two independent spaces with plant seeds and arbuscular mycorrhizal fungal inoculum (generally a mixture of spores, ectomycorrhizal mycelium, and sand), improving planting efficiency and achieving simultaneous inoculation.

[0017] Furthermore, a material distribution box is fixed at each of the discharge ports at the bottom of the cylinder. The material distribution box is connected to the cylinder and the bottom of the material distribution box is connected to the outside. A material distribution shaft is horizontally rotatably connected inside the material distribution box. The material distribution box also has a receiving cavity that cooperates with the outer wall of the material distribution shaft. The outer wall of the material distribution shaft has a groove. A second gear is coaxially fixedly connected to the material distribution shaft. A second rack that meshes with the second gear is axially opened on the side wall of the guide rod.

[0018] Beneficial Effects: This technical solution, by adding a distribution box, ensures a uniform and controllable quantity of plant seeds during each downward movement of the cylinder. Specifically, during the downward movement of the cylinder, the second gear also rotates circumferentially under the action of the second rack, driving the distribution shaft to rotate circumferentially. Because the receiving cavity inside the distribution box cooperates with the distribution shaft, plant seeds cannot fall into the gap between the receiving cavity and the distribution shaft, thus ensuring that the plant seeds can only fall into the grooves opened on the distribution shaft. The plant seeds and inoculum first fall from the groove at the top of the distribution shaft under the action of gravity. During the rotation of the distribution shaft, the plant seeds and inoculum falling into the groove are carried by the distribution shaft to the bottom of the receiving cavity, and then fall out of the receiving cavity under the action of gravity, ultimately achieving the technical effect of distributing plant seeds and inoculum.

[0019] Furthermore, two symmetrical soil-inserting cones are welded and fixed to the bottom of the material distribution box, and the bottom of the soil-inserting cones is pointed.

[0020] Beneficial effects: This technical solution adds a soil-inserting cone so that, during the downward movement of the cylinder, the soil-inserting cone can squeeze the soil to create a pit.

[0021] Furthermore, the guide sleeve has a through hole on the side near the first gear, through which the first gear passes and meshes with the first rack inside the guide sleeve.

[0022] Beneficial effects: This technical solution improves the height of the first gear relative to the guide rod by opening a through hole in the side wall of the guide sleeve, thereby increasing the rotation distance of the first gear and ultimately increasing the vibration frequency of the vibrating wheel.

[0023] Furthermore, the striking block has a spherical structure.

[0024] Beneficial effects: This technical solution uses a spherical striking block to minimize the contact area with the outer wall of the cylinder while providing vibration, thereby reducing wear on the outer wall and effectively extending the service life of the device.

[0025] Furthermore, the flexible pad is made of silicone or rubber.

[0026] Beneficial effects: This technical solution uses silicone or rubber materials to ensure that the flexible pad can play a flexible role, while maximizing the selection of low-cost materials, which is convenient for market application.

[0027] Furthermore, two connecting plates are symmetrically fixed to the side wall of the cylinder near the top, and several parallel hand handles are fixedly connected between the two connecting plates.

[0028] Beneficial effects: This technical solution utilizes two additional fixed connecting plates to fix the hand handle above the cylinder, thereby achieving the technical effect of allowing the hand handle to not affect the feeding of materials into the cylinder, while also facilitating the user's relative displacement of the cylinder.

[0029] Furthermore, a compression spring is fixedly connected to the top of the guide rod, and the top end of the compression spring is fixedly connected to the inner wall of the guide sleeve; when the compression spring is in a free state, the cylinder is located at the highest point relative to the support base.

[0030] Beneficial effects: This technical solution adds a compression spring between the guide rod and the guide sleeve, so that the guide rod can automatically reset under the action of the compression spring after each displacement, effectively improving the efficiency of use.

[0031] Furthermore, the support base also includes a chassis, the bottom end of the guide rod is fixedly connected to the top of the chassis, and a number of legs are fixedly arranged at equal intervals on the bottom of the chassis.

[0032] Beneficial effects: This technical solution achieves the effect of lowering the center of gravity of the overall device by adding a chassis, and improves the stability of the support base by using multiple outriggers.

[0033] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0043] Example 1

[0044] The basics are as follows: Figure 1 Appendix Figure 2 Appendix Figure 3 As shown: An automatic plant planting device for inoculating arbuscular mycorrhizal fungi includes a cylinder 1 and a support base 4.

[0045] The outer contour of the cylinder 1 is cylindrical. A baffle 101 is vertically welded and fixed inside the cylinder 1, dividing the interior into two independent spaces. Each independent space has a discharge port 102 at its bottom, allowing only one plant seed to pass through at a time. Two connecting plates 103 are symmetrically threaded onto the sidewalls of the cylinder 1 near the top, and two parallel hand-held rods 104 are fixedly connected between the two connecting plates 103. A guide sleeve 2 is integrally formed on the sidewall of the cylinder 1, extending parallel to the axial direction of the cylinder 1. The top of the guide sleeve 2 is sealed, while its bottom is connected to the outside. A through hole 3, which is a keyed hole, is vertically formed on the sidewall of the guide sleeve 2.

[0046] Two soil-inserting cones 105 are welded and fixed at the bottom of the cylinder 1 at each discharge port 102. Both soil-inserting cones 105 are solid structures and are stacked together. The bottom ends of the soil-inserting cones 105 are pointed.

[0047] The support base 4 includes a chassis 401. Three legs 402 are arranged circumferentially on the side wall of the chassis 401. The legs 402 and the chassis 401 are integrally formed. A guide rod 403 is vertically fixed to the top of the chassis 401 by a pin. The top of the guide rod 403 is slidably connected to the inside of the guide sleeve 2. A compression spring 5 is fixedly connected between the top of the guide rod 403 and the top of the inner wall of the guide sleeve 2. When the compression spring 5 is in a free state, the cylinder 1 is located at its highest point relative to the support base 4. A first toothed rack 6 is vertically formed on the same side of the guide rod 403 near the through hole 3.

[0048] A mechanical counter 7 is bolted to the outer wall of the cylinder 1. The mechanical counter 7 is a 75-I type rotary counter manufactured by Shanghai Bailu Electronic Counting Co., Ltd. An output shaft 8 is located on the right side of the counter 7. The counter 7 counts by rotating the output shaft 8 circumferentially. The output shaft 8 can rotate in both clockwise and counterclockwise directions, but the counter 7 only counts when the output shaft 8 rotates counterclockwise. A first gear 9 and a vibrating wheel 10 are coaxially keyed to the output shaft 8. The first gear 9 is a spur gear, and it passes through the through hole 3 and meshes with the first rack 6 inside the guide sleeve 2.

[0049] Nine flexible pads 11 are arranged in an array on the outer circumferential wall of the vibrating wheel 10. The flexible pads 11 are glued and fixed to the outer wall of the vibrating wheel 10, and the outer wall of the flexible pads 11 abuts against the outer wall of the cylinder 1. The flexible pads 11 are made of silicone. A spherical striking block 12 is embedded and fixed on the outer wall of the flexible pads 11. The striking block 12 is made of stainless steel.

[0050] The specific implementation process is as follows: During use, the operator first places the automatic planter on the soil, at which point the legs 402 of the support base 4 are inserted into the soil to provide support. Then, the operator puts the plant seeds and inoculum into the two independent spaces inside the cylinder 1 from the top. Then, the operator grips the handle 104 and pushes it vertically downwards.

[0051] During the pushing process, the cylinder 1 will move vertically downward relative to the support base 4. As the cylinder 1 moves downward, the soil-inserting cone 105 at the bottom of the cylinder 1 will be inserted into the soil, achieving the purpose of squeezing the soil to create a pit. During this process, the plant seeds and inoculum will also fall from the discharge port 102 of the cylinder 1 into the soil pit under the action of gravity.

[0052] As the cylinder 1 moves, the first gear 9 on the outer wall of the cylinder 1 also rotates circumferentially due to its meshing with the first rack 6. The rotation of the first gear 9 drives the output shaft 8 to rotate counterclockwise, and the rotation of the output shaft 8 thus realizes the function of the counter 7. Ultimately, every time the operator presses down on the cylinder 1 to insert a seed, the output shaft 8 will rotate once, and the counter 7 will perform one count.

[0053] Furthermore, the rotation of the output shaft 8 simultaneously drives the vibrating wheel 10 to rotate counterclockwise. The vibrating wheel 10 utilizes a flexible pad 11 abutting against the outer wall of the cylinder 1, continuously and intermittently contacting the outer wall of the cylinder 1 during rotation. Each time the flexible pad 11 contacts the cylinder 1, the striking block 12 impacts the outer wall of the cylinder 1, ultimately achieving the technical effect of impact vibration on the cylinder 1. This ensures even distribution of plant seeds and inoculum inside the cylinder 1, preventing blockages.

[0054] Example 2

[0055] The difference between this embodiment and Embodiment 1 is as follows, as shown in the appendix. Figure 4 Appendix Figure 5 As shown, a distribution box 13 is welded and fixed to the bottom of the cylinder 1 at each discharge port 102. The top of the distribution box 13 is connected to the discharge port 102 of the cylinder 1, and the bottom of the distribution box 13 is connected to the outside. A distribution shaft 14 is horizontally rotatably connected inside the distribution box 13. The distribution box 13 also has a receiving cavity 15 that mates with the outer wall of the distribution shaft 14. Eight grooves 16 are evenly spaced along the circumference on the outer wall of the distribution shaft 14. The two distribution shafts 14 are coaxially fixedly connected. At the position between the two distribution boxes 13, a second gear 17 is coaxially keyed and fixed to the distribution shaft 14. A second rack 18 that meshes with the second gear 17 is vertically opened on the guide rod 403 near the second gear 17. The second gear 17 is a spur gear. The flexible pad 11 is made of rubber.

[0056] The specific implementation process is as follows: During the downward movement of the cylinder 1, the second gear 17 also rotates circumferentially under the action of the second rack 18. This rotation of the second gear 17 drives the distributing shaft 14 to rotate circumferentially. Because the receiving cavity 15 inside the distributing box 13 cooperates with the distributing shaft 14, plant seeds cannot fall into the gap between the receiving cavity 15 and the distributing shaft 14. Therefore, the plant seeds can only fall into the groove 16 opened on the distributing shaft 14. The plant seeds first fall into the groove 16 at the top of the distributing shaft 14 under the action of gravity. During the rotation of the distributing shaft 14, the plant seeds falling into the groove 16 are carried by the distributing shaft 14 to the bottom of the receiving cavity 15 and fall out of the receiving cavity 15 under the action of gravity, thus ultimately achieving the technical effect of distributing plant seeds.

[0057] The above descriptions are merely embodiments of the present invention, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
