DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] See also Figure 1-7 The present invention provides a technical solution for a precision fertilization device for corn. The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific operation is as follows.

[0016] A corn precision fertilization device comprises: a shell 11, two feeding pipes 2 and a handle 3. The two feeding pipes 2 are arranged at both ends of the shell 11 in a mirror-image manner. The shell 11 is provided with a plurality of discharge ports 12. The shell 11 is made of a transparent material, and the state of the fertilizer in the shell 11 can be observed. The handle 3 is a U-shaped structure. The two ends of the handle 3 are spline-connected to the two feeding pipes 2. The relative angle between the handle 3 and the feeding pipe 2 is adjusted. When the shell 11 is rotated by holding the handle 3, the feeding pipe 2 and the handle 3 are relatively stationary. The feed pipe 2 and the outer shell 11 are in relative motion, and the feed pipe 2 is connected to a storage box, which is not shown in the figure. The storage box can be installed on the handle 3, and the storage box can also be omitted. The storage capacity of the storage bin 51 can be used to store fertilizers. The outer shell 11 is a columnar structure, and 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, a protrusion or other structure can be added to the annular outer wall of the outer shell 11 to avoid sliding between the outer shell 11 and the ground, which causes uneven fertilization.

[0017] It also includes: two driving components 4, a material storage bin 51 and a material discharge mechanism 6.

[0018] Two driving components 4 are respectively arranged on the two feeding pipes 2. The driving components 4 drive the operation of the material discharging mechanism 6. The two driving components 4 ensure that the force of the material discharging mechanism 6 is uniform. The driving components 4 and the housing 11 are located on the same axis and rotate synchronously with the feeding pipe 2. When the housing 11 rotates, the driving components 4 and the housing 11 produce relative motion. The driving components 4 are composed of a rotating disk 41, a first driving plate 42, a second driving plate 43 and two driving rods 44. The first driving plate 42 and the second driving plate 43 are arranged on the rotating disk 41. The first driving plate 42 and the second driving plate 43 are arranged on the annular outer wall, and the rotation angle between the first driving plate 42 and the second driving plate 43 is 180 degrees. The end face of the first driving plate 42 far from the rotating disk 41 is a plane, and the two sides of the end face are smoothly transitioned with the rotating disk 41. When the first driving plate 42 contacts the pressing frame 644, the pressing frame 644 can be driven to translate along the radial outer side of the shell 11. Two driving rods 44 are arranged on the side of the second driving plate 43 pointing to the inner cavity of the shell 11. The wall surfaces opposite to the two rotating disks 41 are provided with mounting grooves. At the same time, the first driving plate 42 and The second driving plate 43 and the turntable 41 are in different planes. The storage bin 51 is arranged between the two driving components 4. A discharge port 52 corresponding to the discharge port 12 is opened on the outer wall of the storage bin 51. Both ends of the storage bin 51 are open structures. Both ends of the storage bin 51 are rotatably arranged in two mounting grooves. Bearings are arranged in the mounting grooves. The storage bin 51 cooperates with the two turntables 41 to form a complete cavity structure. During the rotation of the storage bin 51, the fertilizer in the storage bin 51 is turned over at the same time. The feed pipe 2 connected to the disk 41 inputs fertilizer into the storage bin 51. The storage bin 51 and the outer shell 11 are on the same axis. At the same time, relative rotation can be generated between the storage bin 51 and the driving component 4. The discharge mechanism 6 is arranged between the storage bin 51 and the inner wall of the outer shell 11 along the radial direction of the outer shell 11, and is located between the discharge port 12 and the discharge port 52. The number of the discharge mechanism 6 can be increased or decreased according to demand, and is distributed in a ring array. The discharge mechanism 6 can reciprocate along the radial direction of the storage bin 51 to perform fertilization operations.

[0019] The discharge mechanism 6 includes: a feed pipe 611 , a connecting pipe 62 , a fixing frame 631 and a discharge assembly 64 .

[0020] The feed pipe 611 is slidably arranged in the discharge port 52. The feed pipe 611 adopts the side opening 612. In the initial state, the opening 612 of the feed pipe 611 is located in the storage bin 51, and the top of the feed pipe 611 is higher than the inner wall of the storage bin 51. At this time, the fertilizer in the storage bin 51 can enter the feed pipe 611 through the opening 612 of the feed pipe 611. At the same time, the top of the feed pipe 611 is an arc-shaped structure, and the arc is consistent with the inner wall of the storage bin 51. When the feed pipe 611 is subjected to external force, the feed pipe 611 will move outward along the radial direction of the storage bin 51. When it moves to the maximum limit, The top surface of the feed pipe 611 and the inner wall of the storage bin 51 are on the same arc surface, so that the fertilizer can be turned over in the storage bin 51 during the rotation of the storage bin 51, thereby ensuring the fluidity of the fertilizer and preventing the fertilizer from being unable to smoothly enter the feed pipe 611. The connecting pipe 62 is arranged at the bottom end of the feed pipe 611, and the fixed frame 631 is installed on the inner wall of the discharge port 12. A rotating groove 632 is opened on the inner wall of the fixed frame 631. The inner cavity of the fixed frame 631 corresponds to the discharge port 12 on the outer shell 11. The discharge assembly 64 is installed at the bottom end of the connecting pipe 62, and the discharge assembly 64 is located in the fixed frame 631.

[0021] The discharging assembly 64 includes: two hoppers, two rotating rods 642 , four pressing rods 643 , a pressing frame 644 , two guiding rods 645 , two springs 646 and two auxiliary assemblies 647 .

[0022] The two hoppers are mirror-imaged and fitted to the bottom end of the connecting tube 62. The two hoppers are symmetrically distributed on the left and right. The top ends of the two hoppers are respectively connected to the two sides of the bottom end of the connecting tube 62. The bottom ends of the two hoppers can be opened and closed. When the bottom ends of the two hoppers are in a closed state, the bottom ends of the two hoppers are in a conical structure to reduce the resistance of the two hoppers inserted into the soil. When no external force is applied, the two hoppers remain in a closed state under the deformation of the connecting tube 62. At the same time, notches are provided at the top corners of the fitting positions of the two hoppers to ensure that the two hoppers can be opened normally. The two rotating rods 642 are respectively provided on the outer walls of the two hoppers and match the rotating groove 632. When 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 rotation axis, and the two hoppers will rotate to an open state at the far end of the connecting pipe 62. Four pressure rods 643 are respectively arranged on the outer walls of the two hoppers, and each two pressure rods 643 form a group and are mirror-imaged on the outer wall of one hopper. The straight-line distance between the pressure rods 643 and the connecting pipe 62 is less than the distance of the rotating rod 642 from the connecting pipe 62 in this direction. The four pressure rods 643 are respectively arranged on the outer walls of the two hoppers in groups of two and close to the connection between the two hoppers. The pressure frame 644 is sleeved on the outer walls of the two hoppers. The pressing frame 644 is on the upper side, and the pressing frame 644 is in contact with the four pressing rods 643. The position where the pressing frame 644 is connected to the pressing rod 643 has a sliding cavity. The pressing rod 643 is located in the sliding cavity. The pressing rod 643 can slide in the horizontal direction. When the pressing frame 644 is subjected to an external force and moves toward the fixed frame 631, the pressing frame 644 will push the pressing rod 643, so that the two hoppers move along the inner cavity of the fixed frame 631 toward the outside of the shell 11. When the rotating rod 642 moves into the rotating groove 632, the pressing frame 644 continues to move. At this time, the far end of the two hoppers from the connecting pipe 62 will rotate to an open state, and the two guide rods 645 will move along the fixed frame 631. The top surface is normally arranged on both sides of the fixed frame 631, and the pressure frame 644 is slidably arranged on the two guide rods 645 to ensure that the pressure frame 644 moves radially along the storage bin 51. The two springs 646 are respectively sleeved on the outer walls 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 spring 646 is used to keep the pressure frame 644 at the maximum limit position 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 an initial state, and the two auxiliary components 647 are respectively installed in the two hoppers.

[0023] Notches are respectively provided at the top corners where the two hoppers are connected, and elastic sealing plates 648 are provided in the notches. When the two hoppers are in an open state, the elastic sealing plates 648 are in a taut state. At the same time, the elastic sealing plates 648 cooperate with the connecting pipe 62 to keep the two hoppers in a closed state when no external force is applied.

[0024] The connecting tube 62 is an elastic tubular structure. The connecting tube 62 can withstand tension or compression in the axial direction without obvious deformation, but has a certain flexibility in the radial direction. The connecting tube 62 can adopt a tubular structure including but not limited to a multi-layer structure.

[0025] The hopper is composed of an upper section 6411 and a lower section 6412, which are hinged. An auxiliary component 647 is used to control the opening and closing state of the lower section 6412 to control fertilization when the hopper does not extend out of the outer shell 11. The connection position between the upper section 6411 and the lower section 6412 is close to the bottom of the entire hopper.

[0026] A spring leaf 6413 is provided on the outer wall of the upper hopper section 6411 and the outer wall of the lower hopper section 6412 . The spring leaf 6413 is used to keep the lower hopper section 6412 and the upper hopper section 6411 in a closed state at all times when no external force is applied.

[0027] The auxiliary component 647 includes: a shaft rod 6471, a lever 6472, a cam 6473, a push rod 6474 and a push rod 6475.

[0028] The shaft 6471 is rotatably arranged on the outer wall of the upper section 6411 of the hopper, and the end of the shaft 6471 passes through the inner cavity of the upper section 6411 of the hopper, the lever 6472 is arranged on the end surface of the shaft 6471 located outside the upper section 6411 of the hopper, the cam 6473 is arranged on the end surface of the shaft 6471 located inside the upper section 6411 of the hopper, the push rod 6474 is slidably arranged on the inner wall of the upper section 6411 of the hopper, and the push rod 6474 and the cam 6473 are located on the same plane, and the rotation of the cam 6473 The push rod 6474 can be pushed to slide, and the push rod 6475 is set on the inner wall of the lower half 6412 of the hopper, and the push rod 6475 and the push rod 6474 are located on the same plane. The lower half 6412 of the hopper is kept in a closed state under the action of the spring 6413. The top end of the push rod 6475 will push the push rod 6474 to make the push rod 6474 at the maximum limit of upward movement. When the cam 6473 rotates, the raised end of the cam 6473 will push the push rod 6474 to move downward and push the push rod 6475, so that the lower half of the hopper is opened.

[0029] One of the levers 6472 in the two auxiliary components 647 is vertically upward, and the other lever 6472 is vertically downward. When the two levers 6472 pass through the two driving rods 44, the two driving rods 44 can simultaneously move the two levers 6472 to open the two lower halves 6412 of the hoppers at the same time.

[0030] Working principle: When surface fertilization is required, the relative angle between the handle 3 and the feed pipe 2 is adjusted so that when the handle 3 is in a suitable 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. At the same time, when the shell 11 is pushed to rotate on the ground, the drive assembly 4 is always in this state, and then the material can be fed into the storage bin 51 through the feed pipe 2. When the discharge 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 bin 51 is located in the fixed frame 631, and the opening 612 of the feed pipe 611 is in the storage bin 51. As the shell 11 rotates, the fertilizer will enter the hopper through the opening 612 of the feed pipe 611. At this time, the handle is held by hand. 3 and push forward. During the rotation of the housing 11, the two driving rods 44 on the second driving plate 43 are always located directly below the turntable 41. When the discharge mechanism 6 moves with the housing 11 to directly below the storage bin 51, the two driving 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 toward the corresponding second section of the hopper, thereby realizing the opening of the second sections of the two hoppers. The fertilizer falls at the moment when the second sections of the two hoppers are opened, and falls on the corresponding ground through the fixed block. As the housing 11 rotates, the above steps are repeated to realize continuous ground fertilization. When deep fertilization is required, the angles of the handle 3 and the feed pipe 2 are adjusted so that the first drive plate 42 is located below the turntable 41 and the second drive plate 43 is located above the turntable 41. When the outer shell 11 rotates, as the discharge mechanism 6 moves to the process directly below the storage bin 51, the fertilizer enters the hopper through the opening 612 of the feed pipe 611. At the same time, the pressing frame 644 in the discharge mechanism 6 gradually contacts the end face of the first drive plate 42 far from the turntable 41. The pressing frame 644 will drive the two hoppers to gradually move to the outside of the outer shell 11 through the pressing rod 643. During the movement, the two hoppers always remain closed, and as the two hoppers are extended, the ends of the two hoppers will be inserted into the soil until the rotating rod 6 42 moves to the rotating groove 632, at this time, the pressing frame 644 continues to move, and the two hoppers will rotate in opposite directions with the corresponding rotating rod 642 as the rotation axis. After the soil is expanded, the fertilizers in the two hoppers will fall into the deep soil. At this time, the pressing frame 644 is at the farthest end of the first driving plate 42 from the turntable 41. As the shell 11 continues to rotate, under the action of the spring 646, the distance between the pressing frame 644 and the storage bin 51 gradually decreases until the pressing frame 644 moves to the maximum limit of the guide rod 645. At this time, the two hoppers are closed, and the two hoppers move back into the shell 11 at the same time, completing a deep fertilization. The above steps are repeated with the rotation of the shell 11 to achieve continuous deep fertilization.
