Description

Technical Field

[0001] This invention relates to the field of intelligent mechanized forestry technology, specifically to an intelligent controlled feeding device for seedling maintenance and fertilization in barren land. Background Technology

[0002] Fertilizer, as an essential component for plant growth, is currently widely used in China. With the advancement of ecological civilization construction, planting and maintaining seedlings on barren land is gradually becoming an important means of ecological restoration and forestry development. In the past, the main method of fertilizing seedlings in barren land was manual fertilization. Manual fertilization requires a large labor input, which is time-consuming and labor-intensive when operating on large areas of barren land, making it difficult to meet the needs of large-scale planting. Therefore, there is an urgent need for a fertilization device that can quantitatively apply fertilizer efficiently, quickly, and labor-savingly.

[0003] Currently, the manufacturing technology of mechanized agricultural and horticultural machinery is quite mature. In terms of fertilization machinery, the types of mechanized machinery manufacturing include fertilizer applicators (chemical fertilizers), fertilizer spreaders, topdressing machines, and inter-row cultivation and topdressing machines, which provide technical support for the intelligent upgrading of seedling fertilization devices in barren land.

[0004] In existing technologies, fertilization devices for infertile land include fixed nozzles combined with automated sensing systems. These systems use sensors to detect soil conditions and control the operation of the fertilization pump and the amount of fertilizer applied. However, when covering multiple rows of seedlings, fixed nozzles cannot evenly fertilize the same seedling, easily leading to areas of over-fertilization. Therefore, movable nozzles are used to fertilize seedlings from multiple angles. Generally, to ensure fertilization effectiveness, the distance between the nozzle and the seedling cannot be too far. Before switching to the next seedling for fertilization, the nozzle cannot automatically adjust its position and retreat after each application. An automated system needs to issue a retreat command after each application. If there is a delay in the control command or mechanical jamming, the nozzle body may easily interfere with the seedling, posing a risk of damaging the nozzle or injuring the seedling. Summary of the Invention

[0012] The intelligent control feeding device for seedling maintenance and fertilization in barren land, as described above, includes an intermittent drive component comprising a drive groove roller, which is rotatably mounted on the movable base. A drive groove is formed on the drive groove roller, and the drive groove roller is driven to rotate by a motor mounted on the movable base.

The telescopic drive shaft is connected to one of the sprockets via a telescopic toothed belt, and the deflection drive shaft is connected to a movable drive component disposed on the support plate via a deflection toothed belt.

[0013] The intelligent control feeding device for seedling maintenance and fertilization in barren land, as described above, has a drive collar slidably arranged on the drive groove roller along the axial direction, drive balls that are movably arranged on the inner wall of the drive collar and adapted to slide with the drive groove, and a connecting hoop is installed on the drive collar.

[0016] Compared with the prior art, the beneficial effects of the present invention are: When the telescopic pusher extends, the spraying component automatically adjusts to the optimal distance from the roots. Driven by the reciprocating moving parts, the protruding pins on the chain move back and forth within the grooves of the sliding plate, causing the telescopic pusher to extend or retract. When fertilizing, the spraying component automatically approaches the seedling roots, maintaining the optimal spraying height and avoiding fertilizer waste or uneven fertilization caused by improper distance in traditional fixed spraying devices. When switching to the next seedling, the spraying component automatically retracts to prevent interference between the curved plate and the seedling, ensuring smooth continuous operation of the device and significantly improving overall fertilization efficiency. The angle adjustment mechanism, combined with the arc-shaped plate design, allows the spray nozzle to move along an arc-shaped trajectory during fertilization, forming a hemispherical fertilization coverage area. Compared to traditional straight-pipe spraying, this effectively expands the fertilizer coverage area, fully covering the soil around the seedling roots and increasing the contact area between fertilizer and soil. Precise control of fertilization depth and range effectively avoids localized soil salinization caused by excessive fertilizer concentration, while simultaneously promoting microbial activity and improving soil structure in infertile areas. The inclined structure of the spray pipe ensures that the nozzle always faces the seedling roots during movement, achieving uniform fan-shaped spraying and preventing concentrated fertilizer and water impact on the same location from burning the seedlings. By combining a visual sensor with a traction mechanism, the system achieves automatic identification and precise positioning of seedlings, effectively solving the problem of manual intervention required by traditional fertilization devices. When the moving base stops moving, the visual sensor identifies the seedling coordinates and sends a signal to the traction mechanism, ensuring that the spray nozzle accurately targets the seedling. This intelligent control not only reduces manual operation costs but also significantly improves the accuracy of fertilization, making it particularly suitable for scenarios with a large number of seedlings and irregular distribution in barren land.

[0028] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0029] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0030] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0031] Please see Figures 1-10 In this embodiment of the invention, a smart control feeding device for seedling maintenance and fertilization in barren land includes a mobile base 1 and a water-fertilizer integrated storage tank set on the mobile base 1, wherein a pumping mechanism 2 is connected to the water-fertilizer integrated storage tank. The movable base 1 is provided with a mounting frame 3, and a telescopic pusher is slidably provided on the mounting frame 3. The movement of the telescopic pusher is driven by a reciprocating movable part provided on the mounting frame 3. An arc-shaped plate 9 is formed at the end of the telescopic pusher, a spraying component is slidably disposed on the arc-shaped plate 9, and an angle adjustment component for pushing the spraying component is installed on the telescopic pusher. The spraying component moves along the arc-shaped trajectory of the arc-shaped plate 9 and fertilizes the seedlings. An intermittent drive component is disposed on the movable base 1 and is connected to the reciprocating moving component and the angle adjusting component, respectively.

[0032] It should be noted that the mounting frame 3 is equipped with a vision sensor, which can identify the position of the seedling and send coordinate signals to the traction mechanism on the moving base 1, so that when the moving base 1 stops moving, the position of the spraying component can be aligned with the seedling. The specific control methods of the vision sensor and the traction mechanism are existing technologies, and this invention will not provide further explanation.

[0033] In this embodiment, when the movable base 1 stops moving, the intermittent drive is activated, briefly transmitting power to the reciprocating moving parts. This allows the telescopic pusher to move relative to the mounting frame 3. The extension of the telescopic pusher brings the sprayer closer to the seedlings, enabling it to automatically adjust to the optimal distance from the seedling roots and maintain the optimal spraying height. This avoids fertilizer waste or uneven fertilization caused by improper distance in traditional fixed spraying devices. The intermittent drive then transmits power to the angle adjustment component. Under the push of the angle adjustment component, the sprayer performs the fertilization action, moving along the arc-shaped trajectory of the arc plate 9 to form a hemispherical fertilization pattern. The coverage area can fully wrap the soil around the seedling roots, increasing the contact area between fertilizer and soil. By precisely controlling the depth and range of fertilization, local soil salinization caused by excessive fertilizer concentration can be avoided. At the same time, it promotes microbial activity and improves soil structure, thereby effectively improving the soil quality of barren plots. After the spraying component moves back and forth relative to the arc plate 9, under the control of the intermittent drive component, its reciprocating component can drive the spraying component to reset, avoiding interference between the arc plate 9 and the seedling when the moving base 1 switches to the position of the next seedling. This design ensures that the device can switch smoothly without manual intervention during continuous operation, improving the overall fertilization efficiency.

[0034] When the spraying component moves relative to the arc plate 9 under the control of the angle adjustment component, the pumping mechanism 2 receives the delivery instruction and delivers water and fertilizer to the spraying component, so that the spraying component can evenly spray fertilizer onto the roots of the seedlings when it moves. The specific pumping volume and control method of the pumping mechanism 2 are existing technologies, and will not be described in detail here.

[0035] As a further embodiment of the present invention, please refer to... Figure 6 The reciprocating moving part includes two sprockets 5, a support plate 4 is mounted on the mounting frame 3, the sprockets 5 are rotatably mounted on the support plate 4, a chain 6 is sleeved between the two sprockets 5, and a protrusion 601 is provided on the chain 6; The reciprocating moving part further includes: a slide plate 7, which is slidably disposed on the support plate 4. A guide groove 701 is formed at one end of the slide plate 7 facing the chain 6. The protrusion 601 can be inserted into the guide groove 701 and is slidably connected with the guide groove 701.

[0036] Driven by the intermittent drive component, when one sprocket 5 rotates, the chain 6 rotates in cooperation with the other sprocket 5. During the rotation of the chain 6, the protrusion 601 on it reciprocates within the guide groove 701. The protrusion 601 presses against the guide groove 701. Under the constraint of the support plate 4, the slide plate 7 reciprocates on the support plate 4. The movement of the slide plate 7 can drive the telescopic pusher to move synchronously, thereby realizing the extension or retraction of the sprayer when fertilizing the seedlings. This ensures that the sprayer can automatically adjust to the optimal distance from the seedling roots, and the sprayer automatically retracts when the position of the moving base 1 is switched to avoid interference with the seedlings.

[0037] As a further embodiment of the present invention, please refer to... Figure 5 The telescopic pusher includes a connecting plate 8, the end of which is connected to the slide plate 7. A receiving plate is symmetrically arranged on the connecting plate 8, and the end of the receiving plate away from the connecting plate 8 is connected to the side end of the arc plate 9.

[0038] The spraying component includes a spray pipe 11, one end of which is connected to the inside of the integrated water and fertilizer storage tank, and the other end forms a nozzle 1101 with an inclined structure. A connecting sleeve 10 is provided along the axis of the spray pipe 11, and a connecting post 1001 is provided on the outer wall of the connecting sleeve 10. An arc groove 901 is formed on the arc plate 9 that is slidably connected to the connecting post 1001.

[0039] The angle adjustment component includes a reciprocating grooved roller 17 rotatably mounted on the connecting plate 8. A reciprocating groove 1701 is formed on the reciprocating grooved roller 17. A slider 16 that is slidably connected to the connecting plate 8 is sleeved along the axial direction of the reciprocating grooved roller 17. A movable ball is movably disposed in the slider 16 and is slidably adapted to the reciprocating groove 1701. The angle adjustment component further includes an elastic limiting component, one end of which is connected to the slider 16 and the other end of which is connected to the connecting sleeve 10.

[0040] The elastic limiting member includes a plug tube 13, which is mounted on the slider 16. A plug rod 14 is slidably inserted into the end of the plug tube 13 away from the slider 16. The end of the plug rod 14 is provided with a connecting frame 12 that is rotatably connected to the connecting sleeve 10. The elastic limiting component further includes a spring 15, which is disposed inside the insertion tube 13. One end of the spring 15 abuts against the inner end of the insertion tube 13, and the other end abuts against the insertion rod 14.

[0041] In the initial state, the spring 15 is in a pre-compressed state. At this time, the connecting column 1001 is located at the side end of the arc groove 901. Driven by the intermittent drive component, when the reciprocating groove roller 17 rotates, the reciprocating slide groove 1701 on it squeezes the moving ball. Under the restriction of the connecting plate 8, the slider 16 moves along the length direction of the connecting plate 8. Driven by the slider 16, the spring 15 is compressed or released under the restriction of the arc groove 901. The spray pipe 11 deviates along the arc trajectory of the arc groove 901. During the deviation process, the nozzle 1101 always faces the root of the seedling, which can achieve uniform spraying of the fan-shaped surface. Compared with the traditional straight pipe spraying, the fertilizer coverage area is effectively expanded. At the same time, it avoids the fertilizer and water from concentrating on the same position and prevents the local concentration from being too high and causing seedling burn.

[0042] In addition, when the spray pipe 11 moves from the beginning of the stroke to the end of the stroke, the trajectory of the spring 15 is pre-compression - gradual compression - the compression potential energy reaches the maximum value - the compression potential energy is released - pre-compression. The setting of the spring 15 prevents the slider 16 from exceeding the stroke range and protects the reciprocating groove roller 17 and the reciprocating slide 1701 from impact loads. In the compression potential energy release stage, the slider 16 can be assisted to return, reducing the energy consumption of the intermittent drive components.

[0043] As a further embodiment of the present invention, please refer to... Figure 9 and Figure 10 The intermittent drive component includes a drive groove roller 26, which is rotatably mounted on the movable base 1. A drive groove 2601 is formed on the drive groove roller 26, and the drive groove roller 26 is driven to rotate by a motor 22 disposed on the movable base 1. The intermittent drive component further includes a telescopic drive shaft 27 and a deflection drive shaft 28, which are rotatably mounted on the movable base 1. The telescopic drive shaft 27 is connected to one of the sprockets 5 via a telescopic toothed belt 30, and the deflection drive shaft 28 is connected to a movable drive component disposed on the support plate 4 via a deflection toothed belt 31.

[0044] A drive collar is slidably disposed on the drive groove roller 26 along the axial direction. Drive balls that are movably disposed on the inner wall of the drive collar and are slidably adapted to the drive groove 2601 are also disposed on the drive collar. A connecting hoop 29 is installed on the drive collar. The telescopic drive shaft 27 and the deflection drive shaft 28 are respectively axially sleeved with a telescopic collar and a deflection collar connected to the connecting hoop 29. The telescopic drive shaft 27 and the deflection drive shaft 28 are respectively formed with a telescopic limiting groove 2701 and a deflection limiting groove 2801. The inner walls of the telescopic collar and the deflection collar are respectively movably arranged with telescopic balls and deflection balls that slide and adapt to the telescopic limiting groove 2701 and the deflection limiting groove 2801.

[0045] In this embodiment, when fertilizing the seedlings, the motor 22 is started. The output shaft of the motor 22 is connected to the drive groove roller 26 through a coupling, so that when the output shaft rotates, it drives the drive groove roller 26 to rotate synchronously. With the cooperation of the drive slide 2601 and the drive ball, the drive collar can make reciprocating linear motion along the axial direction of the drive groove roller 26. The movement of the drive collar can drive the connecting hoop 29 to move synchronously, thereby realizing the requirement that the telescopic collar and the deflection collar can rotate relative to the telescopic transmission shaft 27 and the deflection transmission shaft 28 respectively.

[0046] It should be noted that: the telescopic limiting groove 2701 includes a threaded groove and a first straight groove, and the deflection limiting groove 2801 includes a second straight groove and an inclined groove. When the telescopic balls move relative to each other in the threaded groove, the telescopic drive shaft 27 rotates. At this time, the deflection balls move relative to each other in the second straight groove, and the deflection drive shaft 28 is restricted and stops rotating. When the deflection balls move into the inclined groove, the deflection drive shaft 28 rotates. At this time, the telescopic balls are located in the first straight groove, and the telescopic drive shaft 27 stops rotating. With the cooperation of the telescopic limiting groove 2701 and the deflection limiting groove 2801, the intermittent rotation requirement of the telescopic drive shaft 27 and the deflection drive shaft 28 is achieved.

[0047] As a further embodiment of the present invention, please refer to... Figure 7 and Figure 8 The movable transmission component includes a central shaft 19, which is rotatably mounted on the support plate 4. The central shaft 19 is connected to the driven shaft 24, which is rotatably mounted on the support plate 4, via a transmission bevel gear set 25. The driven shaft 24 is connected to the deflection transmission shaft 28 via a deflection toothed belt 31. A movable collar 23 is slidably sleeved along the axial direction of the central shaft 19. The movable transmission component further includes: a movable shaft 20, which is rotatably mounted on the connecting plate 8. The two ends of the movable shaft 20 are respectively connected to the movable collar 23 and the reciprocating grooved roller 17 via a reciprocating bevel gear set 18. A traction plate 21 with an L-shaped structure is rotatably connected to the movable shaft 20. The end of the traction plate 21 away from the movable shaft 20 is rotatably connected to the movable collar 23.

[0048] Preferably, at least one set of strip blocks 2301 are provided inside the movable collar 23, and a strip groove 1901 is formed on the central shaft 19 to slide and adapt to the strip blocks 2301.

[0049] When the aforementioned deflection drive shaft 28 rotates, the rotation of the intermediate shaft 19 is achieved under the transmission of the deflection toothed belt 31 and the transmission bevel gear set 25. At this time, under the sliding cooperation of the strip block 2301 and the strip groove 1901, the rotation of the intermediate shaft 19 can drive the moving collar 23 to rotate synchronously, and does not affect the linear movement of the moving collar 23 along the axial direction of the intermediate shaft 19. The setting of the traction plate 21 ensures that no matter how the moving collar 23 moves axially, the movable shaft 20 and the intermediate shaft 19 always maintain a meshing transmission state through the reciprocating bevel gear set 18, avoiding the disengagement problem common in traditional structures.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
