Description

Technical Field

[0001] This invention relates to the field of fertilization equipment technology, and in particular to a fertilization machine for thin-shelled pecan planting. Background Technology

[0002] In agricultural planting, fertilizer applicators, as an important type of agricultural machinery, are widely used in the planting process of various crops. Their function is to apply fertilizer to the planting area according to specific requirements through specific devices and operating methods, thereby meeting the nutrient needs of crops, promoting healthy growth, and increasing yield and quality. For the cultivation of pecans (also known as American pecans, whose kernels are edible, delicious, and can be pressed for oil; their tough shells are excellent for military use; and their thin shells and rich nutrition make them popular with consumers, leading to their cultivation not only in mountainous areas but also in some plains), fertilizer applicators play a crucial role. Because pecan trees have a weak root system for absorbing nutrients from the soil during the seedling stage, fertilizer applicators are needed after planting to ensure that the pecan trees receive sufficient nutrients for faster growth.

[0003] Currently, existing fertilizer applicators used in pecan cultivation have the following shortcomings and deficiencies in practical use. Given that the root distribution, nutrient requirements, and trenching depth of pecans are closely related, and that the pecan tree's ability to absorb nutrients from the soil varies at different stages, the choice of fertilization method (dispersed or concentrated) must be determined based on the root layer's needs corresponding to the trenching depth. However, existing fertilizer applicators struggle to accurately determine the appropriate fertilization method and trenching depth. This prevents pecan trees from fully and evenly obtaining the various nutrients necessary for their growth, thus affecting their normal growth, development, yield, and quality. Furthermore, the trenching blades of existing fertilizer applicators wear out quickly during operation, and the cost of repairing and replacing these blades is high. This not only increases planting costs but also affects the continuity and efficiency of fertilization operations due to frequent blade repairs and replacements, hindering the large-scale cultivation of pecans. Therefore, these shortcomings fail to meet user needs, and further improvements are necessary.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings to provide a thin-shelled pecan planting and fertilization machine, in order to achieve a more practical purpose. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a fertilization machine for thin-shelled pecan planting, which is achieved by the following specific technical means: A thin-shelled pecan planting fertilizer applicator includes a frame, a traction frame and a fixing frame mounted on the frame, a storage component mounted on the frame for fertilizer storage, and a fertilizer adjustment mechanism and a ditching mechanism mounted on the fixing frame.

A fixing inclined block is fixed on the upper side of the uniform shell. An adjusting inclined block is fixed to the lower side of the adjusting frame, and the adjusting inclined block is in contact with the inclined surface of the fixed inclined block.

[0008] As a further description of the above technical solution: The fertilization adjustment mechanism also includes a transmission assembly, which includes a first gear fixedly mounted on a drive shaft and a second gear fixedly mounted on a movable shaft. A transmission chain connects the first gear and the second gear.

[0009] As a further description of the above technical solution: The trenching mechanism also includes a cleaning component, which includes a cleaning frame fixedly mounted on the outer wall of the trenching cutter. A cleaning scraper is slidably installed on the inner side of the cleaning frame, and a limiting component is fixedly mounted on the top of the cleaning scraper. A return spring is fixedly connected between the top limiting component of the cleaning scraper and the upper side of the trenching cutter.

[0010] As a further description of the above technical solution: The trenching mechanism also includes a reciprocating assembly, which includes a fixed plate fixedly mounted on the outer wall of the movable sleeve. A servo motor is fixedly mounted on the fixed plate, and three evenly distributed striking rods are fixedly mounted on the output end of the servo motor. A striking block is fixedly mounted on the outer end of each striking rod. The reciprocating assembly also includes a fixed ring fixedly mounted on the outer wall of the movable sleeve, and a movable ring slidably mounted on the outer wall of the movable sleeve. An elastic corrugated rubber ring is fixedly connected between the fixed ring and the movable ring, and the bottom of the movable ring is in contact with the limiting member at the top of the cleaning scraper.

[0011] As a further description of the above technical solution: The storage assembly includes a storage base fixedly mounted on the frame, a storage hopper fixedly installed on the upper side of the storage base, and a storage cover connected to the upper side of the storage hopper by a hinge. The storage base has a discharge channel for guiding fertilizer, and the discharge channel at the bottom of the storage base is fixedly connected to the upper end of the first fertilizer pipe.

[0012] As a further description of the above technical solution: The storage assembly also includes an inclined block fixed inside the storage hopper, an infrared sensor is installed on the inclined block, and an alarm control box is installed on the upper side of the storage seat. The infrared sensor is electrically connected to the alarm control box.

[0013] As a further description of the above technical solution: The fixing frame is fixedly installed with a soil covering component for covering the soil. The soil covering component includes a soil covering rod, one side of which is fixedly connected to the fixing frame by a fixing member, and a soil covering plate is fixedly installed at the bottom of the soil covering rod.

[0014] As a further description of the above technical solution: A pressing assembly is installed on the frame. The pressing assembly includes a pressing frame fixed to the frame and a pressing roller rotatably mounted on the pressing frame. A protective plate is fixed to one side of the pressing frame.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This thin-shelled pecan planting and fertilizing machine addresses the different fertilization requirements at different growth stages of pecan trees. When fertilizing seedling pecan trees, the device fully opens the fertilization port at the bottom of the uniform shell, allowing for a wider fertilization range. This also accommodates the widely distributed root system of seedling pecan trees, ensuring that fertilizer is evenly distributed around the seedling roots, providing sufficient nutrients for their growth. When fertilizing mature pecan trees, the device controls the adjustment of the inclined block, which pushes the fixed inclined block to slide the adjustment sleeve on the uniform shell, thereby reducing the opening degree of the fertilization port and achieving precise control of the fertilization range. This dynamic adjustment mechanism allows for flexible adjustment of the fertilization range according to the actual growth stage and needs of the pecan tree, concentrating fertilizer in designated areas and preventing nutrients from diffusing into non-absorption areas. This ensures that fertilizer is efficiently utilized by the pecan tree roots, reducing waste.

[0016] 2. This thin-shelled pecan planting fertilizer applicator, through the setting of a quantitative roller and its outer quantitative groove, collects fertilizer when the quantitative groove rotates to the bottom of the first fertilizer tube during the fertilization process. Since the quantitative groove has a specific volume, the amount of fertilizer contained in each quantitative groove is basically fixed, thereby enabling precise control of the amount of fertilizer applied each time. Through this precise quantitative fertilization method, it avoids the situation where the pecan tree cannot obtain enough nutrients to support its growth due to insufficient fertilizer application, and the situation where excessive fertilizer application causes soil nutrient imbalance, affecting the pecan tree's absorption of nutrients, thus providing a reliable guarantee for the healthy growth of the pecan tree.

[0017] 3. This thin-shelled pecan planting fertilizer applicator, during the fertilization process, drives the first gear, transmission chain, second gear, and movable shaft to rotate via the drive shaft. This, in turn, causes the uniform plate to rotate within the uniform shell. The rotating uniform plate strikes the falling fertilizer, breaking up the fertilizer's aggregation and ensuring its even distribution. This effectively prevents fertilizer from accumulating in localized areas or leaving blank spots in the soil trenches. This method of evenly distributing fertilizer ensures it falls evenly into the soil trenches, improving fertilizer utilization and providing a more uniform nutrient supply to the pecan trees, which is beneficial for their balanced growth.

[0018] 4. This thin-shelled pecan planting and fertilizing machine addresses the issue of soil adhering to the surface of the trenching blades during trenching operations, forming a mud cake layer that increases the friction coefficient and exacerbates abrasive wear. The device utilizes a servo motor to drive a striking rod and striking block to rotate slowly. The striking block intermittently strikes a movable ring, causing the ring to slide on a movable sleeve and pull on an elastic corrugated rubber ring. This, in turn, causes the cleaning scraper to intermittently move downwards, scraping away the soil adhering to the surface of the trenching blades. This automatic cleaning method promptly restores point contact between the trenching blades and the soil, reduces frictional resistance, effectively extends the service life of the trenching blades, reduces replacement costs and downtime due to blade wear, and improves operational efficiency.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1 to 15A fertilizer applicator for thin-shelled pecan planting includes a frame 10, a traction frame 11 and a fixed frame 12 mounted on the frame 10, a fertilizer storage component 20 mounted on the frame 10 for fertilizer storage, and a fertilizer adjustment mechanism 30 and a trenching mechanism 40 mounted on the fixed frame 12. A fixed bracket 121 is fixedly mounted on the fixed frame 12, and a drive shaft 13 is rotatably mounted on the fixed frame 12. Drive wheels 14 are fixedly mounted at both ends of the drive shaft 13. The fertilizer adjustment mechanism 30 includes a quantitative fertilizer applicator 31, the upper side of which is connected to a first... The fertilizer pipe 32 is connected to the storage component 20, and the lower side is connected to the adjustment component 34 through the second fertilizer pipe 33. The ditching mechanism 40 includes a guide frame 41 fixedly mounted on the first fertilizer pipe 32, and an electric telescopic device 44 fixedly mounted on the fixed frame 12. A movable sleeve 42 is slidably mounted on the guide frame 41. The lower telescopic end of the electric telescopic device 44 is connected to the movable sleeve 42. A ditching cutter 43 for ditching the soil is fixedly mounted on the lower end of the movable sleeve 42. An adjustment frame 47 for adjusting the opening of the fertilizer inlet of the adjustment component 34 is fixedly mounted on one side of the movable sleeve 42.

[0024] By addressing the varying fertilization requirements at different growth stages of pecan trees, this device allows the fertilizer inlet at the bottom of the uniform shell 341 to fully open when fertilizing seedling pecan trees, thus widening the fertilization area. This also accommodates the extensive root distribution of seedling pecan trees, ensuring the fertilizer is evenly distributed around the roots, providing sufficient nutrients for growth. When fertilizing mature pecan trees, the device manipulates the adjusting block 471 to push the fixed block 346, causing the adjusting sleeve 342 to slide on the uniform shell 341, thereby reducing the opening degree of the fertilizer inlet and achieving precise control of the fertilization area. This dynamic adjustment mechanism allows for flexible adjustment of the fertilization area based on the actual growth stage and needs of the pecan tree, concentrating fertilizer application in designated areas and preventing nutrients from diffusing into non-absorption zones. This ensures efficient utilization of fertilizer by the pecan tree roots and reduces waste.

[0025] Please see Figure 1 , Figures 13 to 14 The storage assembly 20 includes a storage seat 21 fixedly mounted on the frame 10. A storage hopper 22 is fixedly installed on the upper side of the storage seat 21, and a storage cover 23 is connected to the upper side of the storage hopper 22 via a hinge. The storage seat 21 has a discharge channel 211 for guiding fertilizer. The outlet of the discharge channel 211 at the bottom of the storage seat 21 is fixedly connected to the upper end of the first fertilizer pipe 32. By loading an appropriate amount of fertilizer into the storage hopper 22, the fertilizer can be continuously and stably supplied during subsequent fertilization. As the tractor pulls the frame 10 to move smoothly in the preset soil area, the fertilizer in the storage hopper 22 slowly slides down the inclined surface of the inner wall under the action of gravity, flows through the discharge channel 211 and the first fertilizer pipe 32 in sequence, and is finally transported to the fertilizer shell 311.

[0026] Please see Figures 13 to 14 The storage assembly 20 also includes an inclined block 24 fixed inside the storage hopper 22. An infrared sensor 25 is installed on the inclined block 24. An alarm control box 26 is installed on the upper side of the storage seat 21. The infrared sensor 25 is electrically connected to the alarm control box 26. The infrared sensor 25 monitors the fertilizer in the storage hopper 22 in real time. When the fertilizer in the storage hopper 22 is insufficient, the infrared sensor 25 sends a signal to the alarm control box 26, which then sounds the alarm and flashes the alarm light on the alarm control box 26, reminding relevant personnel to replenish the fertilizer in the storage hopper 22 in time, thereby further improving the fertilization effect on the soil.

[0027] Please see Figures 6 to 7 The quantitative fertilization component 31 includes a fertilization shell 311 fixed on a fixed bracket 121. A quantitative roller 312 is rotatably installed inside the fertilization shell 311. A drive shaft 13 passes through the fertilization shell 311 and is fixedly connected to the quantitative roller 312. A quantitative groove 313 is provided on the quantitative roller 312. Since the quantitative groove 313 has a specific volume, the amount of fertilizer contained in each quantitative groove 313 is basically fixed, thereby enabling precise control of the amount of fertilizer applied each time. This effectively avoids insufficient fertilizer application, which would prevent the hickory tree from obtaining enough nutrients to support its growth, and excessive fertilizer application, which would cause soil nutrient imbalance and affect the hickory tree's absorption of nutrients.

[0028] Please see Figures 6 to 8 The adjusting assembly 34 includes a uniform shell 341 fixed to the lower end of the second fertilizer pipe 33. The uniform shell 341 has a fertilizer inlet at its bottom and a movable shaft 343 rotatably mounted inside it. A uniform plate 344 is fixed on the movable shaft 343. Adjusting sleeves 342 are movably mounted at both ends of the uniform shell 341. An adjusting spring 345 is connected between the adjusting sleeves 342 and the uniform shell 341. A fixed inclined block 346 is fixed on the upper side of the uniform shell 341. An adjusting inclined block 471 is fixed on the lower side of the adjusting frame 47. The adjusting inclined block 471 is in contact with the inclined surface of the fixed inclined block 346. The movable shaft 343 drives the uniform plate 344 to rotate in the uniform shell 341. The rotating uniform plate 344 will strike the falling fertilizer, breaking the fertilizer's aggregation state when it falls, so that the fertilizer forms a uniformly dispersed state. This effectively avoids the formation of local accumulation or blank areas of fertilizer in the soil trench, ensuring that the fertilizer can fall into the soil trench from the fertilizer inlet at the bottom of the uniform shell 341 evenly.

[0029] Please see Figures 6 to 8The fertilizer adjustment mechanism 30 also includes a transmission assembly 35, which includes a first gear 351 fixedly mounted on the drive shaft 13 and a second gear 352 fixedly mounted on the movable shaft 343. A transmission chain 353 is connected between the first gear 351 and the second gear 352. During the rotation of the drive shaft 13, the first gear 351 is driven to rotate synchronously, and the first gear 351 drives the second gear 352 to rotate through the transmission chain 353. When the second gear 352 rotates, it drives the movable shaft 343 to rotate synchronously.

[0030] Please see Figures 9 to 11 The trenching mechanism 40 also includes a cleaning component 45, which includes a cleaning frame 451 fixedly mounted on the outer wall of the trenching cutter 43. A cleaning scraper 452 is slidably installed on the inner side of the cleaning frame 451, and a limiting component is fixedly mounted on the top of the cleaning scraper 452. A return spring 453 is fixedly connected between the top limiting component of the cleaning scraper 452 and the upper side of the trenching cutter 43. By limiting the cleaning scraper 452 through the cleaning frame 451, the downward-moving cleaning scraper 452 can scrape off the soil adhering to the surface of the trenching cutter 43, thereby exposing the original surface of the trenching cutter 43, restoring its point contact with the soil instead of surface contact, effectively reducing frictional resistance, extending the service life of the trenching cutter 43, and improving work efficiency.

[0031] Please see Figures 9 to 12 The trenching mechanism 40 also includes a reciprocating assembly 46, which includes a fixed plate 461 fixedly mounted on the outer wall of the movable sleeve 42. A servo motor 462 is fixedly mounted on the fixed plate 461. Three evenly distributed striking rods 463 are fixedly mounted on the output end of the servo motor 462. A striking block 464 is fixedly mounted on the outer end of the striking rods 463. The reciprocating assembly 46 also includes a fixed ring 465 fixedly mounted on the outer wall of the movable sleeve 42, and a movable ring 467 slidably mounted on the outer wall of the movable sleeve 42. An elastic wave is fixedly connected between the fixed ring 465 and the movable ring 467. The bottom of the corrugated rubber ring 466 and the movable ring 467 are in contact with the limiting part at the top of the cleaning scraper 452. The output end of the servo motor 462 drives the striking rod 463 and the striking block 464 to rotate slowly. During the rotation, the striking block 464 strikes and pushes the movable ring 467, causing the movable ring 467 to slide downward on the movable sleeve 42. At the same time, it pulls the elastic corrugated rubber ring 466. The elastic corrugated rubber ring 466 is equipped with a spring. As the striking block 464 strikes and pushes the movable ring 467, the movable ring 467 moves down and presses down on the cleaning scraper 452.

[0032] Please see Figures 3 to 5A soil covering component 50 for covering soil is fixedly installed on the fixed frame 12. The soil covering component 50 includes a soil covering rod 51. One side of the soil covering rod 51 is fixedly connected to the fixed frame 12 through a fastener 52. A soil covering plate 53 is fixedly installed at the bottom of the soil covering rod 51. After fertilization, the soil covering plate 53 turns over the soil and covers the fertilizer in the soil trench.

[0033] Please see Figures 1 to 2 , Figure 15 A compaction assembly 60 is installed on the frame 10. The compaction assembly 60 includes a compaction frame 61 fixed on the frame 10 and a compaction roller 62 rotatably installed on the compaction frame 61. A protective plate 63 is fixed on one side of the compaction frame 61. After the covering is completed, the compaction roller 62 compacts the covered soil to further enhance the covering and compaction effect on the fertilized soil, thereby completing the entire automated fertilization process.

[0034] Working principle: First, the entire device is rigidly connected to the external power source (tractor) through the towing frame 11 on the frame 10, so that the two are closely combined into a stable and reliable mobile work platform. At the same time, by adjusting the towing frame 11, the longitudinal tilt angle of the frame 10 during the overall operation can be flexibly adjusted to adapt to different terrains and work requirements. Next, an appropriate amount of fertilizer is loaded into the storage hopper 22 to ensure a continuous and stable supply of fertilizer during subsequent fertilization. As the tractor pulls the frame 10 to move smoothly in the preset soil area, the device begins to perform trenching and fertilization operations. During the trenching process, the trenching blade 43 uses its sharp angle to insert into the soil. As the frame 10 drives the trenching blade 43 to move, a soil trench of moderate depth and uniform width is formed. At the same time, the fertilizer in the storage hopper 22 slides slowly down the inclined surface of the inner wall under the action of gravity, flows through the discharge channel 211 and the first fertilizer pipe 32 in sequence, and is finally transported to the fertilizer shell 311. As the frame 10 moves on the soil, the drive wheel 14 contacts the soil and rotates, thereby driving the drive shaft 13 to rotate synchronously. When the drive shaft 13 rotates, it will drive the metering roller 312 to rotate synchronously. A number of metering grooves 313 for fertilization are provided on the outer periphery of the metering roller 312. When the metering groove 313 rotates to the bottom of the first fertilizer tube 32, due to the gap in the space below the fertilizer, some fertilizer falls into the metering groove 313 under the action of gravity. Since the metering groove 313 has a specific volume, the amount of fertilizer contained in each metering groove 313 is basically fixed, so that the amount of fertilizer applied each time can be precisely controlled. This effectively avoids the problem of insufficient fertilizer application causing the hickory tree to not obtain enough nutrients to support growth, and excessive fertilizer application causing soil nutrient imbalance, which affects the absorption of nutrients by the hickory tree. As the drive shaft 13 continues to drive the metering roller 312 to rotate, when the metering trough 313 rotates to the bottom and is opposite to the position of the second fertilizer tube 33, the fertilizer in the metering trough 313 will fall into the second fertilizer tube 33 through the opening at the bottom of the fertilizer shell 311, and then fall into the uniform shell 341 along the second fertilizer tube 33. At the same time, the drive shaft 13 drives the first gear 351 to rotate synchronously during the rotation. The first gear 351 drives the second gear 352 to rotate through the transmission chain 353. When the second gear 352 rotates, it drives the movable shaft 343 to rotate synchronously. The movable shaft 343 then drives the uniform plate 344 to rotate in the uniform shell 341. The rotating uniform plate 344 will strike the falling fertilizer, breaking the aggregation state of the fertilizer when it falls, so that the fertilizer forms a uniformly dispersed state, effectively avoiding the formation of local accumulation or blank areas of fertilizer in the soil trench, ensuring that the fertilizer can be evenly dispersed from the fertilizer opening at the bottom of the uniform shell 341 into the soil trench, completing the fertilizer application operation. After fertilization, the soil covering plate 53 turns over the soil to cover the fertilizer in the soil trench. Then, the pressing roller 62 presses the covered soil to further enhance the covering and pressing effect of the fertilized soil, thus completing the entire automated fertilization process. Furthermore, the setting of the fertilizer inlet at the bottom of the uniform shell 341 being fully open facilitates fertilization of seedling hickory trees, allowing for a wider fertilization range. This meets the characteristics of the wide root distribution of seedling hickory trees, ensuring that the fertilizer can be evenly distributed around the seedling roots, providing sufficient nutrients for their growth. When fertilizing mature hickory trees, the fertilization area needs to be more concentrated, and deeper trenches need to be dug in the soil. At this time, the electric telescopic device 44 is activated by operating an external switch. The telescopic end of the electric telescopic device 44 pushes the movable sleeve 42 to slide downwards on the guide frame 41. The movable sleeve 42 drives the trenching cutter 43 to move downwards synchronously to the designated height. During the downward movement of the movable sleeve 42, it also drives the adjusting frame 47 and the adjusting inclined block 471 to move downwards synchronously. Since the inclined surface of the adjusting inclined block 471 is in contact with the inclined surface of the fixed inclined block 346, the downward-moving adjusting inclined block 471 pushes the fixed inclined block 346 towards the first... The second fertilizer tube 33 moves in the direction of the fixed inclined block 346, which in turn drives the adjusting sleeve 342 to slide on the uniform shell 341. As the adjusting sleeve 342 moves towards the uniform shell 341, the size of the fertilizer opening at the bottom of the uniform shell 341 is adjusted, reducing the opening degree of the fertilizer opening, thereby adjusting and changing the fertilization range. Through this dynamic adjustment mechanism, the fertilization range can be precisely controlled according to actual needs, so that the fertilizer is concentrated in the absorption area of ​​the root system of mature hickory trees, avoiding the diffusion of nutrients to non-absorption areas, ensuring that the fertilizer is efficiently utilized by the root system of mature hickory trees, and reducing waste caused by dispersion. Furthermore, during the trenching operation of the trenching cutter 43, soil adheres to the surface of the trenching cutter 43, forming a mud cake layer, which increases the friction coefficient between the trenching cutter 43 and the soil, and aggravates abrasive wear. At this time, the servo motor 462 is activated. The output end of the servo motor 462 drives the striking rod 463 and the striking block 464 to rotate slowly. During the rotation, the striking block 464 strikes and pushes the movable ring 467, causing the movable ring 467 to slide downward on the movable sleeve 42, while pulling the elastic corrugated rubber ring 466. The elastic corrugated rubber ring 466 is equipped with a spring. As the striking block 464 strikes and pushes the movable ring 467, the movable ring 467 moves down and presses down on the cleaning scraper 452. The cleaning frame 451 limits the cleaning scraper 452, causing the downward-moving cleaning scraper 452 to clean the soil adhering to the surface of the trenching cutter 43. The soil is scraped away, exposing the original surface of the trenching tool 43 and restoring its point contact with the soil instead of surface contact. This effectively reduces frictional resistance, extends the service life of the trenching tool 43, and improves work efficiency. When the striking block 464 separates from the movable ring 467, the movable ring 467 is pulled back to its original position by the elastic force of the elastic corrugated rubber ring 466 and the internal spring. At the same time, the cleaning scraper 452 is driven to reset by the elastic force of the reset spring 453. The striking rod 463 and the striking block 464 are driven to rotate slowly by the output end of the servo motor 462, which allows the striking block 464 to intermittently strike the movable ring 467. This causes the cleaning scraper to move down intermittently and scrape away the soil adhering to the surface of the trenching tool 43, further reducing the wear of the trenching tool 43, extending its service life, and improving work efficiency.
