Description

Technical Field

[0001] The present invention relates to the field of rice planting, and in particular to a rice planting device and a method for using the same. Background Art

[0002] At present, in the research on rice planting and cultivation, experimental fields are generally set up to conduct rice planting observation experiments. During the rice planting and cultivation experiment, various fertilizers need to be applied to the rice, which will eventually be absorbed by the roots of the rice.

[0003] In order to speed up the absorption of fertilizer by the roots of rice, the existing technology adds a device in the soil to make the fertilizer flow directly into the soil. For example, the "A Rice Planting Device" with application number "201911133960.4" includes a pool body, a main conveying rod, a solid conveying support rod and a liquid conveying support rod; the pool body has a accommodating space with an upper opening; the main conveying rod is arranged horizontally and inserted on the peripheral wall of the pool body and extends into the bottom of the accommodating space. A partition plate is provided in the middle of the main conveying rod to divide the internal space into a solid conveying chamber and a liquid conveying chamber; the solid conveying support rod is connected to the solid conveying chamber; the liquid conveying support rods are symmetrically arranged on both sides of the part of the main conveying rod extending into the accommodating space and are connected to the liquid conveying chamber. The solid delivery support rods and the liquid delivery support rods are arranged along the main delivery rod, which can evenly apply fertilizer to the soil. The solid delivery support rods and the liquid delivery support rods are respectively connected to the solid delivery cavity and the liquid delivery cavity to deliver fertilizer into the soil, so as to achieve the separation of solid and liquid fertilizers and deliver them to the root position of rice, thereby achieving accurate fertilization, improving fertilizer utilization and reducing the delay in fertilizer absorption by rice.

[0004] However, existing methods for delivering nutrients to rice roots are too diffuse. Because the entire tank is large and the delivery rods are widely distributed, the fertilization effect on individual rice plants is limited. Therefore, the present invention designs a device that can deliver fertilizer to individual rice roots, accelerating the absorption of fertilizer by the rice roots and thus speeding up the progress of rice cultivation experiments.

DETAILED DESCRIPTION

[0050] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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 making creative efforts shall fall within the scope of protection of the present invention.

[0051] Example

[0052] Reference Figures 1-12 A rice planting device includes a pool body 1. The structure of the pool body 1 is the existing technology, that is, a receiving space with an upper opening, the receiving space is used to fill a layer of soil and water to plant rice.

[0053] Reference Figure 1 A plurality of rice supply components are arranged in the pool body 1, and the rice supply components include a conveying pipe 4, a supply ring 2 and a plurality of extension pipes 3 equidistantly arranged in an annular shape on the inner wall of the supply ring 2.

[0054] Reference Figure 1 and Figure 2 The supply rings 2 are arranged horizontally and equidistantly in the pool body 1. They are ring-shaped with open top and bottom for soil, water and rice seedlings to pass through. Each rice plant can be stored separately through the supply rings 2, so that the roots of a single rice plant can be supplemented with nutrients separately, ensuring that the roots of each rice plant have uniform and sufficient nutrients.

[0055] Furthermore, in some embodiments, the supply ring 2 includes a fixed outer ring 20 and a movable inner ring 21. The setting of the fixed outer ring 20 and the movable inner ring 21 can achieve a reasonable distribution of solid nutrients and liquid nutrients. Specifically, three methods of separate distribution of solid nutrients, separate distribution of liquid nutrients, and mixed distribution of solid and liquid nutrients can be achieved.

[0056] The fixed outer ring 20 is fixed at the end of the conveying pipe 4, and the feed channel is a solid conveying ring channel 200 and a liquid conveying ring channel 201 arranged in the ring wall of the fixed outer ring 20, and the solid conveying ring channel 200 and the liquid conveying ring channel 201 are staggered, wherein the staggered arrangement means that the inner diameters of the solid conveying ring channel 200 and the liquid conveying ring channel 201 are different and are not on the same horizontal plane, and a solid conveying channel 202 for downward conveying is provided at the bottom of the solid conveying ring channel 200, and a liquid conveying channel 203 for downward conveying is provided at the bottom of the liquid conveying ring channel 201.

[0057] It should be supplemented that: the solid conveying ring channel 200 and the liquid conveying ring channel 201 are respectively provided with a feed port and a discharge port, wherein the feed port and the discharge port are respectively connected to the opposite ends of two adjacent conveying pipes 4.

[0058] An annular cavity is also provided in the ring wall of the fixed outer ring 20, and the annular cavity is located in the middle position of the fixed outer ring 20. The movable inner ring 21 rotates in the annular cavity, and an arc-shaped trough 210 corresponding to the number of extension tubes 3 is provided on its top. The arc-shaped trough 210 is provided with an arc-shaped discharge port 211 near the bottom of the side wall of the extension tube 3. The arc-shaped discharge port 211 corresponds to the position of the feed port of the extension tube 3, and the solid or solid and liquid nutrients in the arc-shaped trough 210 are transferred from the arc-shaped discharge port 211 to the extension tube 3.

[0059] It is necessary to add that:

[0060] 1. The solid feed channel 202 and the liquid feed channel 203 are staggered. When the top of the arc-shaped trough 210 is open and aligned with the solid feed channel 202, only solid nutrients are transported. Similarly, when the top of the arc-shaped trough 210 is open and aligned with the liquid feed channel 203, only liquid nutrients are transported. However, when liquid nutrients are being transported, if the arc-shaped trough 210 contains solid nutrients, the liquid nutrients are injected, and the mixed solid and liquid nutrients are transported.

[0061] 2. To ensure sealing, a sealing gasket is provided on the outer wall of the fixed outer ring 20, and the sealing gasket slides along the inner wall of the annular cavity;

[0062] 3. To facilitate the rotation of the dynamic inner ring 21, in this embodiment, the rotation of the dynamic inner ring 21 adopts a wire-driven method. For details, refer to Figure 2 and Figure 3 A wire channel 5 is provided at the bottom of the conveying tube 4. A pull wire A6 is installed within the channel. The ends of the pull wire A6 are connected to the outer walls of two adjacent movable inner rings 21. The outer walls of the movable inner rings 21 are provided with hanging grooves for the pull wire A6. Simply pulling the pull wire A6 at one end, the pull wire A6 transmits power between the pull wire A6 and the movable inner rings 21, braking the multiple movable inner rings 21 to rotate synchronously.

[0063] Furthermore, in order to facilitate the resetting of the dynamic inner ring 21 after being pulled by the pull wire A6, preferably, the outer wall of the dynamic inner ring 21 and the inner wall of the annular cavity are connected by a torsion spring 7, wherein an embedded torsion spring mounting groove is provided at the bottom of the inner wall of the dynamic inner ring 21, and a torsion spring 7 mounting cavity is formed between the torsion spring mounting groove and the annular cavity, thereby preventing the torsion spring 7 from protruding from the outer wall of the dynamic inner ring 21 after installation, thereby affecting the rotation of the dynamic inner ring 21.

[0064] Reference Figure 1 The conveying pipe 4 is connected between two adjacent supply rings 2, and includes a solid conveying channel 40 and a liquid conveying channel 41. The solid conveying channel 40 and the liquid conveying channel 41 are connected to the feed channel, wherein the solid conveying channel 40 and the liquid conveying channel 41 are arranged up and down, and are separated by a partition.

[0065] Reference Figure 1 The extension tube 3 is tilted and tilted toward the central axis of the supply ring 2, so that the nutrients automatically flow down under their own gravity without the need for external driving force. In addition, the extension tube 3 is connected to the supply channel.

[0066] In some embodiments, reference Figure 4 and Figure 5 The extension tube 3 includes an upper stop 30 , a material cavity 31 and an end wall 34 .

[0067] The top wall and bottom wall of the upper gear seat 30 are arranged in parallel, and the left and right ends are arc-shaped walls, in which a material channel 300 is arranged. The material channel 300 is distributed along the length of the upper gear seat 30, and a linear discharge port 301 is arranged below the material channel 300. The nutrients flowing out from the arc-shaped discharge port 211 enter the material channel 300 and are further discharged downward through the linear discharge port 301.

[0068] The material chamber 31 is formed by a lower wall and the bottom wall of the upper stop 30. The lower wall is composed of a middle sealing platform 32 and two movable curved walls 33 on either side. Furthermore, curved slideways 302 are provided on both sides of the bottom of the upper stop 30. The movable curved walls 33 slide within these curved slideways. The middle sealing platform 32 is connected to the upper stop 30. Furthermore, nutrients flowing from the linear discharge port 301 enter the material chamber 31. Further, the nutrients enter the soil layer through the channel formed between the rotating movable curved walls 33 and the middle sealing platform 32.

[0069] The top and bottom walls of the end wall 34 are arranged in parallel, and the left and right ends are semicircular walls. There are two of them, one at the upper stop seat 30 and the other at the ends of the material chamber 31. One of the end walls 34 is provided with a material port 340, the two ends of which are connected to the material channel 300 and the arc-shaped discharge port 211. It should be added that to facilitate the installation of the extension tube 3, the inner wall of the fixed outer ring 20 is provided with a socket for inserting the extension tube 3, and mounting seats are provided on both sides of the end wall 34. The extension tube 3 is installed by bolts on the mounting seats.

[0070] Based on the arrangement of the movable arc-shaped wall 33, this embodiment discloses a driving structure of the movable arc-shaped wall 33 to achieve synchronous and opposite rotation of the two movable arc-shaped walls 33 and thus open the material chamber 31. The structure is arranged as follows:

[0071] First, a driving ring 8 rotates inside the fixed outer ring 20. Specifically, an annular cavity for the driving ring 8 to rotate is provided inside the ring wall of the fixed outer ring 20, and a tooth groove is provided on the outer wall of the driving ring 8. Since the extension tube 3 is arranged at an angle, the tooth surface of the tooth groove is arranged perpendicular to the extension tube 3. The tooth groove is engaged with a gear rod 80, and a screw 81 is fixed at one end of the gear rod 80; two adjacent driving rings 8 are connected by a pull wire B9, and the pull wire B9 is located in the wire channel 5, wherein the setting and installation method of the pull wire B9 are exactly the same as those of the pull wire A6, and are not described in detail here. In addition, it should be added that the length of the gear rod 80 is greater than the length of the tooth groove, and the two are always engaged, ensuring that the screw 81 is not affected by the gear rod 80 during rotation and can always rotate.

[0072] Secondly, a protrusion is provided on the outer wall of one of the end walls 34, and the screw 81 is threaded through the protrusion and rotatably connected to the connecting seat 82, and the connecting seat 82 slides on the end wall 34; based on the setting of the protrusion, the screw 81 can achieve synchronous linear movement during the rotation process, and the screw 81 can be installed at the same time through the protrusion.

[0073] Finally, one end of the movable arc-shaped wall 33 passes through the end wall 34 and is fixed with a driving disk 83. The two driving disks 83 are connected to the same connecting seat 82 through an eccentrically arranged connecting rod 84. It should be added that: the two connecting rods 84 are symmetrically arranged about the connecting seat 82, so that the two driving disks 83 are synchronously driven to rotate with the linear movement of the connecting seat 82, and further, the movable arc-shaped wall 33 is driven to rotate synchronously in the opposite direction, thereby opening the material chamber 31.

[0074] Reference Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 and Figure 9 The middle sealing platform 32 slides linearly under the upper gear seat 30, and when the material chamber 31 is in a sealed state, the bottom of the middle sealing platform 32 protrudes from the bottom of the movable arc wall 33. The movement of the middle sealing platform 32 can increase the infiltration area of nutrient. When the material chamber 31 is in a closed state, the soil in the tank body 1 cannot pass through the lower surrounding wall. When the two movable arc walls 33 move in opposite directions and are stored, and the middle sealing platform 32 moves upward, the original position of the movable arc wall 33 and the middle sealing platform 32 is saved. After the nutrient enters this area, the nutrient is retained in the soil. Based on the linear movement of the middle sealing platform 32, the area below it can also be used for nutrient entry, thereby increasing the contact surface between the nutrient and the soil; in addition, after the middle sealing platform 32 moves downward, the nutrient below it can be squeezed, thereby trying to achieve full infiltration of the nutrient into the soil. At the same time, through the repeated linear movement of the middle sealing platform 32, the nutrient in the material chamber 31 can also be completely discharged to the outer wall of the material chamber 31 in the closed state.

[0075] In some embodiments, the linear motion of the middle sealing platform 32 and the movable arc-shaped wall 33 can generate a continuous motion. Preferably, the transmission structure between the two is as follows:

[0076] Method 1: Reference Figure 10 A 7-shaped slide bar 320 is fixed on the top of the middle sealing platform 32. The 7-shaped slide bar 320 slides linearly in the upper gear seat 30. The horizontal end of the 7-shaped slide bar 320 extends into the arc-shaped slideway 302. When the movable arc-shaped wall 33 is received in the arc-shaped slideway 302, the movable arc-shaped wall 33 contacts the horizontal end of the 7-shaped slide bar 320, thereby braking the middle sealing platform 32 to lift upward.

[0077] In addition, the top of the middle sealing platform 32 and the upper gear seat 30 are connected by a return spring 321. When the movable arc wall 33 rotates outward from the arc slide 302, the return spring 321 causes the middle sealing platform 32 to move downward, thereby pressing the nutrients below it. After the middle sealing platform 32 stops moving, the movable arc wall 33 continues to rotate downward until the material chamber 31 is closed. However, if the solid nutrients in the material chamber 31 cannot be completely discharged under the movement of the middle sealing platform 32 and the movable arc wall 33 in one time, the movement of the middle sealing platform 32 and the movable arc wall 33 can be repeated. Under repeated action, after the middle sealing platform 32 moves upward, there is empty space, allowing nutrients on both sides to enter. As the middle sealing platform 32 moves downward, the nutrients below the middle sealing platform 32 are squeezed. Repeating this movement multiple times can see that the solid materials in the material chamber 31 are completely discharged.

[0078] Method 2: Reference Figure 11 and Figure 12 In this embodiment, a double-headed screw 322 rotates in the upper gear seat 30, and a gear 323 is fixed to the end of the double-headed screw 322. The inner wall of the movable arc wall 33 is provided with a driving gear ring protrusion 324 and a limiting gear ring protrusion 325 that mesh with the gear 323. The gear 323 is located between the driving gear ring protrusion 324 and the limiting gear ring protrusion 325. The initial state is referred to Figure 11 , the gear 323 does not contact the limiting tooth ring protrusion 325, and rotates with the movable arc wall 33 through the limiting tooth ring protrusion 325. The middle sealing platform 32 does not move after the gear 323 disengages the limiting tooth ring protrusion 325, and the material chamber 31 is opened by the movable arc walls 33 on both sides; when the gear 323 contacts the driving tooth ring protrusion 324, the middle sealing platform 32 moves downward synchronously, thereby vacating the area below it, facilitating the entry of nutrients. Furthermore, the two ends of the double-headed screw 322 are threadedly connected to the threaded slide 326, and the bottoms of the two threaded slides 326 are connected to the middle sealing platform 32 through an inclined connecting rod 327. The double-headed screw 322, the threaded slide 326 and the connecting rod 327 serve as a transmission assembly. When the gear 323 engages with the driving tooth ring protrusion 324, it rotates through the movable arc wall 33, realizing the linear movement of the middle sealing platform 32.

[0079] Finally, it should be noted that: 1. The top of the central sealing platform 32 is shaped like a figure eight and corresponds to the bottom of the linear discharge port 301. This facilitates the uniform flow of nutrients into the movable curved walls 33 on both sides. 2. The pulling method of the pull wires A6 and B9 can be manual or electrical. The electrical pulling method can use motor winding or other methods. These are conventional technical means and are not described in detail.

[0080] The method of using the rice planting device is as follows:

[0081] S1. Installation: Install the rice supply assembly in the tank body 1. The installation position of the rice supply assembly in the tank body 1 can be determined by the filling amount of the bottom soil;

[0082] S2. Filling: Fill the pool 1 with soil until it covers the rice supply assembly;

[0083] S3. Nutrient replenishment: Nutrients are replenished in the supply ring 2 and the extension tube 3 through the delivery pipe 4. The delivery of solid nutrients, liquid nutrients or mixed nutrients can be controlled by pulling the pull wire A6;

[0084] S4. Nutrients enter the soil: By pulling the pull wire B9, the material chamber 31 is opened, causing the nutrients to flow into the original lower wall area, achieving contact between the nutrients and the soil; when the nutrients in the material chamber 31 need to be completely discharged, the pull wire B9 can be pulled back and forth, causing the middle sealing platform 32 of the lower wall to achieve reciprocating up and down linear movement. The middle sealing platform 32 moves upward, opening the area below the middle sealing platform 32 to facilitate the inflow of nutrients; the middle sealing platform 32 moves downward, squeezing the nutrients in the area below the middle sealing platform 32.

[0085] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
