[0041] 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.
[0042] Please see Figure 1-7 This invention provides a technical solution for a precision fertilization device for corn. Its detailed connection method is a well-known technology in the field. The working principle and process are mainly described below. The specific work is as follows.
[0043] A precision fertilization device for corn includes: a housing 11, two feeding pipes 2, and a handle 3. The two feeding pipes 2 are rotatably mounted at both ends of the housing 11. The housing 11 has several discharge ports 12. The housing 11 is made of transparent material, allowing observation of the fertilizer's condition inside. The handle 3 has a U-shaped structure, and its two ends are splined to the two feeding pipes 2. By adjusting the relative angle between the handle 3 and the feeding pipes 2, the feeding pipes 2 and the handle 3 remain relatively stationary while the housing 11 is rotated by holding the handle 3. The conveying pipe 2 and the outer shell 11 are in relative motion. The conveying pipe 2 is connected to the storage box, which is not shown in the figure. The storage box can be installed on the handle 3. Alternatively, the storage box can be omitted, and the storage capacity of the storage bin 51 can be used to store fertilizer. The outer shell 11 has a columnar structure. The annular outer wall of the outer shell 11 is in contact with the ground. In order to ensure that the outer shell 11 can still rotate normally when in contact with the ground, protrusions or other structures can be added to the annular outer wall of the outer shell 11 to prevent the outer shell 11 from sliding with the ground, which would cause uneven fertilization.
[0044] It also includes: two drive components 4, a storage bin 51 and a feeding mechanism 6.
[0045] Two drive components 4 are respectively mounted on two conveying pipes 2. The drive components 4 drive the operation of the feeding mechanism 6. The two drive components 4 ensure that the force on the feeding mechanism 6 is uniform. The drive components 4 and the outer shell 11 are located on the same axis and rotate synchronously with the conveying pipes 2. When the outer shell 11 rotates, the drive components 4 and the outer shell 11 generate relative motion. The drive components 4 consist of a turntable 41, a first drive plate 42, a second drive plate 43, and two drive rods 44. The first drive plate 42 and the second drive plate 43 are mounted on the turntable 41. On the annular outer wall, the rotation angle between the first drive plate 42 and the second drive plate 43 is 180 degrees. The far end face of the first drive plate 42 is flat, and the two sides of this end face smoothly transition with the turntable 41. When the first drive plate 42 contacts the pressure frame 644, it can drive the pressure frame 644 to translate radially outward along the outer side of the outer shell 11. Two drive rods 44 are provided on the side of the second drive plate 43 pointing towards the inner cavity of the outer shell 11. Mounting grooves are provided on the opposing wall surfaces of the two turntables 41. At the same time, the first drive plate 42 and The second drive plate 43 and the turntable 41 are in different planes. The storage bin 51 is located between the two drive components 4. The outer wall of the storage bin 51 has a discharge port 52 corresponding to the discharge port 12. The storage bin 51 has an open structure at both ends. The two ends of the storage bin 51 are rotatably mounted in two mounting slots. Bearings are installed in the mounting slots. The storage bin 51 and the two turntables 41 form a complete cavity structure. During the rotation of the storage bin 51, the fertilizer in the storage bin 51 is simultaneously flipped and rotated by the two turntables. Fertilizer is fed into the storage bin 51 through the conveying pipe 2 connected to the disc 41. The storage bin 51 and the outer shell 11 are on the same axis. At the same time, the storage bin 51 and the drive assembly 4 can rotate relative to each other. The discharging mechanism 6 is arranged radially between the storage bin 51 and the inner wall of the outer shell 11, and is located in the outlet 12 and the discharge port 52. The number of discharging mechanisms 6 can be increased or decreased according to the needs. They are distributed in a ring array. The discharging mechanism 6 can move back and forth radially along the storage bin 51 to carry out fertilization operations.
[0046] The feeding mechanism 6 includes: a feeding pipe 611, a connecting pipe 62, a fixed frame 631, and a discharging assembly 64.
[0047] The feed pipe 611 is slidably disposed within the discharge port 52. The feed pipe 611 adopts a side opening 612. In the initial state, the opening 612 of the feed pipe 611 is located inside the storage silo 51, and the top of the feed pipe 611 is higher than the inner wall of the storage silo 51. At this time, the fertilizer in the storage silo 51 can enter the feed pipe 611 through the opening 612. At the same time, the top of the feed pipe 611 has an arc-shaped structure, and the curvature is consistent with the inner wall of the storage silo 51. When the feed pipe 611 is subjected to external force, the feed pipe 611 will move radially outward along the storage silo 51. When it moves to the maximum limit, The top surface of the feed pipe 611 is on the same arc surface as the inner wall of the storage silo 51, so that the fertilizer can be turned over in the storage silo 51 during rotation, ensuring the fluidity of the fertilizer and preventing the fertilizer from failing to enter the feed pipe 611 smoothly. The connecting pipe 62 is set at the bottom end of the feed pipe 611. The fixing frame 631 is installed on the inner wall of the discharge port 12. The inner wall of the fixing frame 631 is provided with a rotating groove 632. The inner cavity of the fixing frame 631 corresponds to the discharge port 12 on the outer shell 11. The discharge component 64 is installed at the bottom end of the connecting pipe 62 and is located inside the fixing frame 631.
[0048] The discharge assembly 64 includes: two hoppers, two rotating rods 642, four pressure rods 643, a pressure frame 644, two guide rods 645, two springs 646, and two auxiliary components 647.
[0049] Two hoppers are mirror-mounted at the bottom of the connecting pipe 62, symmetrically distributed left and right. The tops of the two hoppers are connected to the two sides of the bottom of the connecting pipe 62, respectively. The bottoms of the two hoppers can be opened and closed. When the bottoms of the two hoppers are closed, they have a conical structure to reduce the resistance of the hoppers when inserted into the soil. Under normal conditions, the two hoppers remain closed due to the deformation of the connecting pipe 62. At the same time, notches are provided at the apex of the mating positions of the two hoppers to ensure that the two hoppers can be opened normally. Two rotating rods 642 are respectively set on the outer walls of the two hoppers and are matched with the rotating groove 632. After the rotating rod 642 moves into the rotating groove 632, if the two hoppers continue to move, the rotating rod 642 will serve as the axis of rotation, and the far end of the two hoppers from the connecting pipe 62 will rotate to the open state. Four pressure rods 643 are respectively set on the outer walls of the two hoppers, with each pair of pressure rods 643 forming a group, and mirror-image positioned on the outer wall of one hopper. The straight-line distance between the pressure rod 643 and the connecting pipe 62 is less than the distance of the rotating rod 642 from the connecting pipe 62 in that direction. The four pressure rods 643 are set in pairs on the outer walls of the two hoppers, close to the connection point between them. The pressure frame 644 is fitted onto the outer walls of the two hoppers. The pressure frame 644 abuts against four pressure rods 643. A sliding cavity is located at the connection point between the pressure frame 644 and the pressure rods 643, and the pressure rods 643 are located within the sliding cavity. The pressure rods 643 can slide horizontally. When the pressure frame 644 is subjected to external force and moves towards the fixed frame 631, the pressure frame 644 will push the pressure rods 643, thereby causing the two hoppers to move along the inner cavity of the fixed frame 631 towards the outside of the outer casing 11. When the rotating rod 642 moves into the rotating groove 632, the pressure frame 644 continues to move. At this time, the far end of the two hoppers from the connecting pipe 62 will rotate to the open state, and the two guide rods 645 move along the fixed frame 631. The top surface is normally set on both sides of the fixed frame 631. The pressure frame 644 is slidably set on the two guide rods 645 to ensure that the pressure frame 644 moves radially along the storage bin 51. Two springs 646 are respectively sleeved on the outer wall of the two guide rods 645, and the two springs 646 are respectively located between the pressure frame 644 and the fixed frame 631. The elastic force of the springs 646 is used to keep the pressure frame 644 at the maximum limit at the top of the two guide rods 645. At the same time, the two hoppers are located between the outer wall of the storage bin 51 and the inner wall of the outer shell 11. The feed pipe 611 is in the initial state. Two auxiliary components 647 are respectively installed in the two hoppers.
[0050] The two hoppers are connected at the top corners with notches and elastic sealing plates 648 are installed in the notches. When the two hoppers are in the open state, the elastic sealing plates 648 are in the taut state. At the same time, the elastic sealing plates 648, together with the connecting pipe 62, keep the two hoppers in the closed state when they are not subjected to external force.
[0051] The connecting pipe 62 has an elastic tubular structure. The connecting pipe 62 can withstand tension or compression in the axial direction without significant deformation, but has a certain degree of flexibility in the radial direction. It can adopt a tubular structure including but not limited to a multi-layer structure.
[0052] The hopper consists of an upper section 6411 and a lower section 6412, which are hinged together. An auxiliary component 647 controls the opening and closing of the lower section 6412, so that fertilization can be controlled when the hopper is not outside the outer shell 11. The connection between the upper section 6411 and the lower section 6412 is close to the bottom of the whole hopper.
[0053] Springs 6413 are provided on the outer walls of the upper half 6411 and the lower half 6412 of the hopper. The springs 6413 are used to keep the lower half 6412 and the upper half 6411 of the hopper closed at all times when they are not subjected to external force.
[0054] The auxiliary component 647 includes: shaft 6471, lever 6472, cam 6473, push rod 6474, and push rod 6475.
[0055] A shaft 6471 is rotatably mounted on the outer wall of the upper half of the hopper 6411, with its end penetrating into the inner cavity of the upper half of the hopper 6411. A lever 6472 is mounted on the end face of the shaft 6471 located on the outside of the upper half of the hopper 6411. A cam 6473 is mounted on the end face of the shaft 6471 located inside the upper half of the hopper 6411. A push rod 6474 is slidably mounted on the inner wall of the upper half of the hopper 6411, with the push rod 6474 and the cam 6473 located on the same plane. The rotation of the cam 6473... The push rod 6474 can be pushed to slide, and the top rod 6475 is set on the inner wall of the lower half of the hopper 6412. The top rod 6475 and the push rod 6474 are located on the same plane. The lower half of the hopper 6412 is kept closed under the action of the spring 6413. The top of the top rod 6475 will push the push rod 6474, so that the push rod 6474 is at the maximum upward limit. When the cam 6473 rotates, the protruding end of the cam 6473 will push the push rod 6474 downward, push the top rod 6475, thereby opening the lower half of the hopper.
[0056] One of the two auxiliary components 647 has a lever 6472 pointing vertically upwards and the other lever 6472 pointing vertically downwards. When the two levers 6472 pass the two drive rods 44, the two drive rods 44 can simultaneously move the two levers 6472, causing the lower halves of the two hoppers 6412 to open simultaneously.
[0057] Working principle:
[0058] When surface fertilization is needed, adjust the relative angle between the handle 3 and the conveying pipe 2 so that when the handle 3 is in the appropriate position, the first drive plate 42 in the drive assembly 4 is at the top of the turntable 41, and the second drive plate 43 is at the bottom of the turntable 41. Simultaneously, while pushing the outer casing 11 to rotate on the ground, the drive assembly 4 remains in this state. Then, fertilizer can be conveyed into the storage hopper 51 through the conveying pipe 2. When the discharging mechanism 6 is not in contact with the drive assembly 4, under the action of the spring 646, the far end of the hopper from the storage hopper 51 is located within the fixed frame 631, and the opening 612 of the feed pipe 611 is inside the storage hopper 51. As the outer casing 11 rotates, fertilizer will enter the hopper through the opening 612 of the feed pipe 611. At this time, the handle is held... 3. Push forward. During the rotation of the outer shell 11, the two drive rods 44 on the second drive plate 43 are always directly below the turntable 41. When the feeding mechanism 6 moves with the outer shell 11 to directly below the storage bin 51, the two drive rods 44 simultaneously abut against the two levers 6472 in the two auxiliary components 647. The cam 6473 in the auxiliary component 647 rotates and pushes the push rod 6474 to slide. The push rod 6475 moves in the same direction as the push rod 6474 and pushes open the corresponding second section of the hopper, thereby opening the second section of the two hoppers. The fertilizer falls at the moment the second section of the two hoppers opens and falls onto the corresponding ground via the fixing block. As the outer shell 11 rotates, the above steps are repeated to achieve continuous ground fertilization.
[0059] When deep fertilization is required, adjust the angles of handle 3 and conveying pipe 2 so that the first drive plate 42 is below the turntable 41 and the second drive plate 43 is above the turntable 41. As the outer casing 11 rotates, fertilizer enters the hopper through the opening 612 of the feed pipe 611 as the discharging mechanism 6 moves directly below the storage bin 51. Simultaneously, the pressure frame 644 in the discharging mechanism 6 gradually contacts the end face of the first drive plate 42 at the far end of the turntable 41. The pressure frame 644 will drive the two hoppers to gradually move outward from the outer casing 11 via the pressure rod 643. During the movement, the two hoppers remain closed, and as the two funnels extend, the ends of the two hoppers will insert into the soil until the rotating rod 6... 42 moves into the rotating trough 632. At this time, the pressure frame 644 continues to move, and the two hoppers will rotate in opposite directions with the corresponding rotating rod 642 as the axis of rotation. After the soil is opened up, the fertilizer in the two hoppers will fall into the soil depth. At this time, the pressure frame 644 is at the farthest end of the first drive plate 42 from the turntable 41. As the outer shell 11 continues to rotate, under the action of the spring 646, the distance between the pressure frame 644 and the storage bin 51 gradually decreases until the pressure frame 644 moves to the maximum limit of the guide rod 645. At this time, the two hoppers close and move back into the outer shell 11 to complete one deep fertilization. The above steps are repeated with the rotation of the outer shell 11 to achieve continuous deep fertilization.
