Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural intelligent fertilization, in particular to an agricultural intelligent fertilization device. BACKGROUND

[0002] In the process of orchard planting, the fruit trees need to be fertilized regularly to ensure the healthy growth of the fruit trees and improve the quality of the fruits. In the fertilization process, a ditch is first dug along the outside of the rows of fruit trees at a certain distance by turning or by digging, and then the fertilizer is spread in the ditch.

[0003] However, due to the large root system of fruit trees (such as apple, citrus, and peach trees), even if the ditch is dug outside the rows of fruit trees for fertilization, directly spreading the fertilizer in a pile in the ditch will cause the following problems: on the one hand, the fertilizer dissolved in the soil after being spread in a pile will form a local high-concentration area (especially for easily soluble fertilizers such as nitrogen and potassium fertilizers), and when the root system contacts the high-concentration solution, the cytoplasm will lose water due to osmosis, leading to cell dehydration and death (i.e., "burning roots"); on the other hand, the fruit tree roots have a tendency to grow towards the fertilizer, and if the fertilizer is spread in a pile, it cannot be fully mixed with the soil, and the newly grown absorbing roots (white roots) directly contact the high-concentration fertilizer, further increasing the risk of burning roots. Therefore, we propose an agricultural intelligent fertilization device. SUMMARY

Detailed Implementation

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] Example 1

[0055] An intelligent agricultural fertilization device includes a traction frame 1, which is connected to an external traction device. In this application, the traction frame 1 is an adjustable-length traction component 66, which is suitable for connecting to traction devices of different heights. The adjustable height setting further enables the traction height of the traction frame 1 to be adjusted according to the ground.

[0056] The bottom of the traction frame 1 is equipped with a protective cover 2, and the protective cover 2 is equipped with a digging and turning mechanism 3. The digging and turning mechanism 3 digs holes for the fruit trees before fertilizing them.

[0057] A reinforcing bracket 21 is also fixedly installed on the protective cover 2, and an exchange box 4 is fixedly installed on the other end of the reinforcing bracket 21. The reinforcing bracket 21 has reinforcing ribs inside to ensure the support strength of the reinforcing bracket 21. A fertilizer injection component 5 is installed on the exchange box 4, and a loose soil pusher 6 is also connected to the exchange box 4. The loose soil pusher 6 guides part of the excavated loose soil into the exchange box 4.

[0058] The bottom of the other end of the exchange box 4 is provided with a discharge port 41, and the fertilizer mixed with the loose soil falls into the pit through the discharge port 41;

[0059] The soil pushing component 6 includes an inlet inclined pipe 61, an inlet component 62, a push-pull frame 63, a baffle plate 64, a drive component 65, a traction component 66, and a mixing component 67. One end of the inlet inclined pipe 61 is connected to the exchange box 4. The bottom of the inlet inclined pipe 61 is provided with an inlet inclined port 611. The inlet inclined pipe 61 is made of reinforced steel material, and the bottom of the inlet inclined port 611 is a digging end 612. The digging end 612 at the bottom ensures the function of further digging.

[0060] The inlet component 62 is located inside the inlet inclined tube 61, and the inlet component 62 is used to introduce part of the loose soil into the exchange box 4 through the inlet inclined tube 61;

[0061] The inlet component 62 includes an inlet rod 621 and an inlet spiral blade 622. The inlet rod 621 is located inside the inlet inclined tube 61, and the other end of the inlet rod 621 is rotatably connected to the top of the exchange box 4. A rotating component 623 is provided on the outer side of the top of the exchange box 4, and the rotating component 623 is used to drive the inlet rod 621.

[0062] The inlet spiral blade 622 is fixedly sleeved on the outside of the inlet rod 621, and the inlet spiral blade 622 extends from the inlet inclined tube 61 into the inside of the exchange box 4;

[0063] As a further explanation, the rotating component 623 includes a rotating motor, a first rotating gear and a second rotating gear. The rotating motor is fixedly installed on the top of the exchange box 4, and the output end of the rotating motor is fixedly connected to the first rotating gear. The first rotating gear is meshed with the second rotating gear, and the second rotating gear is fixedly sleeved on the outer side of the top of the guide rod 621.

[0064] Meanwhile, in agriculture, the soil turned up when digging a pit is usually loose soil, which is a soil state in which the gaps between soil particles increase and the structure becomes loose after the soil structure is destroyed.

[0065] Specifically: When the traction frame 1 pulls the exchange box 4 through the protective cover 2 and the reinforcing fixing frame 21, the digging and turning mechanism 3 digs the pit and turns out the loose soil, making the loose soil in a loose state. At this time, the rotating motor runs, causing the first rotating gear to drive the second rotating gear to rotate. When the second rotating gear rotates, the guide rod 621 drives the guide spiral blade 622 to rotate, which further assists the loose soil to enter the inside of the guide inclined tube 61 through the guide inclined opening 611, and finally enter the inside of the exchange box 4 through the top of the guide inclined tube 61.

[0066] While the inclined tube 61 is moving, the digging end 612 at its bottom simultaneously assists in digging.

[0067] The push-pull frame 63 is slidably connected inside the exchange box 4, and the bottom and top of the push-pull frame 63 are both open.

[0068] The push-pull frame 63 has an inlet 631 on the side near the guide tube 61, and a baffle 64 is provided at the inlet 631. The drive unit 65 is provided on one side of the push-pull frame 63, and the drive unit 65 is used to drive the baffle 64.

[0069] The driving component 65 includes a drive shaft 651, a drive motor 652, a protective shell 653, a drive support rod 654, a fixed side plate 655, a connecting shaft 656, a connecting support rod 657, and a fixed shaft 658. The drive shaft 651 passes through one side of the push-pull frame 63 and is rotatably connected to the push-pull frame 63. The drive motor 652 is installed on the outside of the push-pull frame 63 and is used to drive the drive shaft 651. The protective shell 653 is fixedly installed on the outside of the push-pull frame 63 and is used to protect the drive motor 652. The exchange box 4 has a movable groove corresponding to the position of the protective shell 653, and the protective shell 653 is slidably connected to the movable groove. The movable groove is provided to facilitate the movement of the protective shell 653, and during the movement, the protective shell 653 pushes out the soil inside the movable groove and prevents the soil from accumulating in the movable groove.

[0070] One end of the drive shaft 651 located inside the push-pull frame 63 is fixedly connected to the drive support rod 654, and the other end of the drive support rod 654 is rotatably connected to the fixed side plate 655 through a pin. The fixed side plate 655 is fixedly installed on the baffle plate 64.

[0071] One end of the connecting shaft 656 is fixedly connected to the fixed side plate 655, and the other end of the connecting shaft 656 is rotatably connected to the connecting support rod 657. The end of the connecting support rod 657 away from the connecting shaft 656 is rotatably connected to the fixed shaft 658, and the fixed shaft 658 is fixedly installed inside the push-pull frame 63.

[0072] Specific implementation process: In this application, before the push-pull frame 63 moves from the discharge port 41 along the end of the exchange box 4 near the inlet inclined tube 61, the baffle plate 64 is located at the inlet 631 and the inlet 631 is in a closed state. The baffle plate 64 and the bottom of the push-pull frame 63 are in a chasing state. At this time, the drive motor 652 runs, thereby causing the drive shaft 651 to drive the drive support rod 654 to rotate. When the drive support rod 654 rotates, it further pushes the fixed side plate 655. Due to the limiting effect of the connecting support rod 657, when the drive support rod 654 stops rotating, the baffle plate 64 is located at the top of the inlet 631. At the same time, the baffle plate 64 and the bottom of the push-pull frame 63 are in a parallel state. At this time, the inlet 631 at the push-pull frame 63 is in an open state. Subsequently, the push-pull frame 63 moves along the inside of the exchange box 4, that is, it moves towards the left end inside the exchange box 4.

[0073] As the push-pull frame 63 continues to move along the inside of the exchange box 4, the loose soil entering the exchange box 4 enters the push-pull frame 63 through the inlet 631. Until the push-pull frame 63 moves in the reverse direction, the drive motor 652 then runs, causing the baffle plate 64 to close the inlet 631. At this time, a certain amount of loose soil enters the push-pull frame 63 and moves along the feed inlet 42 with the push-pull frame 63, that is, it moves towards the right end of the exchange box 4. This process is repeated, and the baffle plate 64 opens and closes the inlet 631.

[0074] The mixing component 67 is disposed inside the push-pull frame 63. The mixing component 67 includes a first rotating shaft 671, a second rotating shaft 672, a first helical gear 673, a second helical gear 674, a fixed shell 675, a synchronizing rod 676, and a traveling component 677. The first rotating shaft 671 and the second rotating shaft 672 respectively pass through one side of the push-pull frame 63, and both the first rotating shaft 671 and the second rotating shaft 672 are rotatably connected to the push-pull frame 63. A stirring plate 678 is fixedly connected to one end of the first rotating shaft 671 and the second rotating shaft 672 located inside the push-pull frame 63, and a plurality of mixing rods 679 are fixedly installed on one side of the stirring plate 678.

[0075] The first rotating shaft 671 and the second rotating shaft 672 are connected to each other by a synchronous component 68 located at one end outside the push-pull frame 63. The synchronous component 68 is composed of gears and gear belts, thereby enabling the first rotating shaft 671 and the second rotating shaft 672 to rotate synchronously.

[0076] The first helical gear 673 is fixedly installed on the first rotating shaft 671, and the first helical gear 673 is meshed with the second helical gear 674. The fixed housing 675 is fixedly installed on the outside of the push-pull frame 63, and the synchronizing rod 676 passes through the fixed housing 675. The synchronizing rod 676 is rotatably connected to the fixed housing 675, and one end of the synchronizing rod 676 located inside the fixed housing 675 is fixedly connected to the second helical gear 674.

[0077] The other end of the fixed rod is connected to the traveling component 677, and the exchange box 4 is provided with a traveling groove at the position corresponding to the traveling component 677.

[0078] The traveling component 677 includes a traveling gear 6771 and a guide rack 6772. The traveling gear 6771 is fixedly mounted on the synchronizing rod 676, and the traveling gear 6771 is meshed with the guide rack 6772. The guide rack 6772 is fixedly mounted at the bottom of the traveling groove.

[0079] Specific implementation process: In this application, when the push-pull frame 63 moves to the left or right relative to the inside of the exchange box 4, the walking gear 6771 is always engaged with the guide rack 6772, and thus the walking gear 6771 rotates relative to the guide rack 6772. When the walking gear 6771 rotates, the fixed rod drives the second helical gear 674 to rotate, and the second helical gear 674 drives the first helical gear 673 to rotate. Thus, the first rotating shaft 671 and the second rotating shaft 672 rotate synchronously under the connection of the synchronizing member 68. At this time, the two sets of mixing rods 679 rotate at the bottom of the push-pull frame 63, so as to achieve the effect of fully mixing the loose soil and fertilizer.

[0080] The traction component 66 is located on the side of the push-pull frame 63 away from the inlet 631, and the traction component 66 is mounted on the exchange box 4;

[0081] As a further supplementary explanation, the traction component 66 includes a telescopic traction strut assembly 661, as shown in the appendix to the instruction manual. Figure 10 Furthermore, one end of the telescopic traction support rod assembly 661 is connected to the push-pull frame 63, and the other end of the telescopic traction support rod assembly 661 is connected to the inner wall of the exchange box 4. At the same time, a movable seat 662 is also connected to the telescopic traction support rod assembly 661. The exchange box 4 has a movable opening corresponding to the movable seat 662. A reciprocating screw 663 is provided on the outside of the movable opening, and a synchronous shaft 664 is fixedly connected to one end of the reciprocating screw 663. A rotary motor 665 is installed on the outside of the exchange box 4. The rotary motor 665 is used to drive the synchronous shaft 664. In this application, the reciprocating screw 663 is the existing reciprocating screw 663, and its screw has two staggered rotating grooves on the outside, which will not be described in detail here.

[0082] Specific implementation process: When the rotary motor 665 is running, it drives the reciprocating screw 663 to rotate synchronously through the synchronous shaft 664. The reciprocating screw 663 provides driving force to the moving seat 662, and then the moving seat 662 drives the traction support rod to extend and retract relative to the inside of the exchange box 4, so that the push-pull frame 63 reciprocates relative to the inside of the exchange box 4.

[0083] The fertilizer injection unit 5 includes a storage box 51, a discharge hood 52 and a discharge control unit 53. The storage box 51 is fixedly installed on the top of the exchange box 4, and the bottom of the storage box 51 is connected to the discharge hood 52. The exchange box 4 is provided with an inlet 42 corresponding to the position of the discharge hood 52, and the inlet 42 is located to the left of the discharge port 41.

[0084] The discharge control component 53 is located outside the discharge hood 52, and a mating component 54 is provided on one side of the top of the exchange box 4. The mating component 54 is connected to the discharge control component 53.

[0085] The discharge control component 53 includes a movable outer cover 531, a buffer connector 532, a closing block 533, and a locking component 534. The movable outer cover 531 is slidably sleeved on the outside of the bottom of the discharge cover 52. Multiple buffer connectors 532 are provided, and multiple buffer connectors 532 are installed on both sides of the outside of the discharge cover 52. The buffer connectors 532 are connected to the movable outer cover 531. Openings are provided on both sides of the bottom of the movable outer cover 531. The closing block 533 is fixedly installed on the bottom of the movable outer cover 531. The closing block 533 is used to close the bottom of the discharge cover 52.

[0086] As a supplementary explanation, the buffer connector 532 includes a buffer rod and a buffer spring. The bottom of the buffer rod is fixedly connected to the discharge cover 52, and the buffer spring is sleeved on the outside of the buffer rod. The movable outer cover 531 is slidably sleeved on the outside of the buffer rod, and the two ends of the buffer spring are fixedly connected to the movable outer cover 531 and the buffer rod, respectively.

[0087] A connecting wedge 535 is fixedly connected to one side of the top of the movable outer cover 531, and the connecting wedge 535 is connected to the mating part 54.

[0088] Two locking components 534 are provided, and the two locking components 534 are installed on both sides of the sliding box, and the movable outer cover 531 has locking holes corresponding to the positions of the locking components 534.

[0089] The locking component 534 includes a support rod 5341, a locking plate 5342, a locking rod 5343, and an extension rod 5344. There are two support rods 5341, one end of each of the two support rods 5341 is fixedly connected to the outside of the exchange box 4, and the locking plate 5342 is slidably sleeved on the outside of the two support rods 5341. A compression spring 5345 is sleeved on the outside of the support rod 5341. One end of the compression spring 5345 is fixedly connected to a support block 5346, and the support block 5346 is fixedly installed on the support rod 5341. The other end of the compression spring 5345 is fixedly connected to the locking plate 5342. One end of the locking rod 5343 is fixedly connected to the locking plate 5342, and the locking rod 5343 is engaged with the locking hole.

[0090] One end of the extension rod 5344 is fixedly connected to the locking plate 5342, and the end of the extension rod 5344 away from the locking plate 5342 is a bent contact end;

[0091] As a further supplementary explanation, the mating component 54 includes a mating wedge 541 and a mating push rod 542. The mating wedge 541 is fixedly installed on one side of the top of the push-pull frame 63, and the exchange box 4 is provided with a mating opening corresponding to the position of the mating wedge 541. There are two mating push rods 542, which are fixedly installed on both sides of the mating wedge 541, and the mating push rods 542 are located above the mating opening.

[0092] Specific implementation process: In this application, when the push-pull frame 63 moves along the inside of the exchange box 4, that is, when the push-pull frame 63 is completely moved to the left side of the discharge port 41, and at the same time the inside of the push-pull frame 63 is filled with a lot of loose soil, then at this time, the mating inclined block 541 of the push-pull frame 63 moves to the connecting inclined block 535, and drives the connecting inclined block 535 to move down. At the same time as the connecting inclined block 535 moves down, it simultaneously drives the moving outer cover 531 to move down. At the same time as the moving outer cover 531 moves down, the closing block 533 disengages from the bottom of the discharge cover 52. At this time, the discharge cover... With the bottom of 52 open, fertilizer falls, and at the same time, the two locking rods 5343 on the outside of the movable outer cover 531 are respectively engaged with the movable outer cover 531, so that the closing block 533 at the movable outer cover 531 is always separated from the discharge cover 52. Then, as the multiple mixing rods 679 rotate, the fertilizer inside the push-pull frame 63 is fully mixed with the loose soil. The mixed fertilizer enters the dug pit from the discharge port 41 as the push-pull frame 63 moves, until the baffle plate 64 of the push-pull frame 63 moves close to the discharge cover 52.

[0093] At this time, the bent contact ends of the two cooperating push rods 542 and the extension rods 5344 are released, thereby causing the two extension rods 5344 to drive the locking plate 5342 and the locking rod 5343 to disengage from the movable outer cover 531. Then, under the connection of multiple buffer connectors 532, the movable outer cover 531 moves upward relative to the discharge cover 52 until the bottom of the discharge cover 52 is closed by the closing block 533. At this time, the fertilizer will no longer fall.

[0094] The exchange box 4 is provided with a landfill mechanism 7 on the side away from the reinforcing frame 21. The landfill mechanism 7 landfills the mixed fertilizer. In this application, the landfill mechanism 7 is composed of a transmission gear assembly, a transmission rod and a transmission spiral blade. The transmission rod is rotatably connected to the bottom of the exchange box 4. The two ends of the transmission gear assembly are respectively connected to the synchronous shaft 664 and the transmission rod. At the same time, there are two transmission spiral blades. The two transmission spiral blades are respectively installed at both ends of the transmission rod, and the spiral directions of the two transmission spiral blades are opposite.

[0095] Multiple height-adjustable wheels 8 are also installed on both sides of the outside of the exchange box 4.

[0096] Specific implementation process: Then, when the fertilizer mixed with loose soil falls into the pit, the transmission rod rotates synchronously. Through the rotation of the two transmission helical blades, the excess loose soil on the outside of the pit is fully buried on top of the mixed fertilizer, thereby achieving the effect of fully fertilizing and burying the fertilizer.

[0098] Example 2 is a further supplementary description of Example 1. Specifically, the digging and turning mechanism 3 includes a support shaft 31, a rotating sleeve 32, a rotating blade 33, and a rotating assembly 34. The support shaft 31 is rotatably connected to the protective cover 2. Multiple rotating sleeves 32 are provided and are fixedly installed on the support shaft 31 at equal intervals. Multiple rotating blades 33 are provided and are fixedly installed around the rotating sleeve 32.

[0099] The rotating assembly 34 is disposed on one side outside the protective cover 2, and the rotating assembly 34 is used to drive the supporting rotating shaft 31. In this application, the rotating assembly 34 is preferably composed of a servo motor and a gear assembly, as shown in the appendix to the specification. Figures 3 to 4 ;

[0100] Furthermore, in this application, multiple rotating sleeves 32 are provided, and multiple rotating blades 33 are provided on the outside of the rotating sleeves 32. When the traction frame 1 pulls the protective cover 2 forward along the outside of the row of fruit trees, the rotating component 34 operates, causing the support shaft 31 to rotate. When the support shaft 31 rotates, it drives the multiple rotating sleeves 32 and the rotating blades 33 to rotate synchronously. While the rotating blades 33 are rotating, they perform the function of loosening the soil and digging pits.
