DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, 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 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.

[0022] Example Reference Figure 1-Figure 12 A rice planting device comprises a pool body 1. The structure of the pool body 1 is the prior art, that is, a receiving space with an upper opening, and the receiving space is used to fill a layer of soil and water to plant rice.

[0023] 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 which are equidistantly arranged in an annular shape on the inner wall of the supply ring 2.

[0024] Reference Figure 1 and Figure 2The 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. The supply rings 2 are used to store and feed each rice plant separately, so that the roots and stems of each rice plant can be supplemented with nutrients separately, ensuring that the nutrients of each rice plant are uniform and sufficient.

[0025] Furthermore, in some embodiments, the supply ring 2 includes a fixed outer ring 20 and a movable inner ring 21. The fixed outer ring 20 and the movable inner ring 21 are configured to 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.

[0026] The fixed outer ring 20 is fixed at the end of the conveying pipe 4, and the feed material 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.

[0027] It should be supplemented that: a feed port and a discharge port are respectively provided on the solid conveying annular channel 200 and the liquid conveying annular channel 201 , wherein the feed port and the discharge port are respectively connected to the opposite ends of two adjacent conveying pipes 4 .

[0028] 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 the top thereof. 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, so that 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.

[0029] It is necessary to add that: 1. The solid material conveying channel 202 and the liquid material conveying channel 203 are arranged in a staggered manner. When the top of the arc-shaped trough 210 is open and aligned with the solid material conveying channel 202, only solid nutrients are conveyed; similarly, when the top of the arc-shaped trough 210 is open and aligned with the liquid material conveying channel 203, only liquid nutrients are conveyed. However, when conveying liquid nutrients, the arc-shaped trough 210 contains solid nutrients, and with the injection of liquid nutrients, the conveying of the mixed solid and liquid nutrients is realized; 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; 3. To facilitate the inner ring 21 to be driven to rotate, in this embodiment, the inner ring 21 is driven by a wire. For details, refer to Figure 2 and Figure 3 A wire channel 5 is provided at the bottom of the conveying pipe 4, and a pull wire A6 is provided in the wire channel 5. The two ends of the pull wire A6 are respectively connected to the outer walls of two adjacent moving inner rings 21, wherein the outer wall of the moving inner ring 21 is provided with a hanging groove for installing the pull wire A6. It is only necessary to pull the pull wire A6 at the end, and after pulling, the pull wire A6 and the moving inner ring 21 are mutually transmitted to brake the multiple moving inner rings 21 to rotate synchronously.

[0030] 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 and affecting the rotation of the dynamic inner ring 21.

[0031] Reference Figure 1 The delivery pipe 4 is connected between two adjacent supply rings 2, and includes a solid delivery channel 40 and a liquid delivery channel 41. The solid delivery channel 40 and the liquid delivery channel 41 are connected to the supply material channel, wherein the solid delivery channel 40 and the liquid delivery channel 41 are arranged up and down and separated by a partition.

[0032] Reference Figure 1 The extension pipe 3 is tilted and the tilting direction is toward the central axis of the supply ring 2, so that the nutrients automatically flow down under the action of their own gravity without external driving force. In addition, the extension pipe 3 is connected to the supply material channel.

[0033] In some embodiments, reference Figure 4 and Figure 5 The extension tube 3 includes an upper stopper 30 , a material cavity 31 and an end wall 34 .

[0034] 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.

[0035] The material cavity 31 is formed by the lower surrounding wall and the bottom wall of the upper gear seat 30, and the lower surrounding wall is composed of the middle sealing platform 32 and the movable arc-shaped walls 33 on both sides thereof. Further, arc-shaped slideways 302 are also provided on both sides of the bottom of the upper gear seat 30, and the movable arc-shaped wall 33 slides in the arc-shaped slideway 302, and the middle sealing platform 32 is connected to the upper gear seat 30. Further, the nutrients flowing down from the linear discharge port 301 enter the material cavity 31, and further, the nutrients enter the soil layer through the channel formed between the movable arc-shaped wall 33 and the middle sealing platform 32 after the movable arc-shaped wall 33 rotates.

[0036] The top wall and the bottom wall of the end wall 34 are arranged in parallel, and the left and right ends are semicircular walls, two in number, which are arranged at the ends of the upper gear seat 30 and the material cavity 31, respectively. A material port 340 is arranged on one of the end walls 34, and the two ends of the material port 340 are respectively connected with the material channel 300 and the arc-shaped discharge port 211. It should be added that in order 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 arranged on both sides of the end wall 34, and the installation of the extension tube 3 is achieved by bolts on the mounting seats.

[0037] Based on the setting of the movable arc-shaped wall 33, this embodiment discloses a driving structure of the movable arc-shaped wall 33 to realize synchronous reverse rotation of the two movable arc-shaped walls 33 and thus open the material chamber 31. The structure is set as follows: First, a driving ring 8 rotates inside the fixed outer ring 20. Specifically, an annular cavity for driving the ring 8 to rotate is provided inside the ring wall of the fixed outer ring 20. A tooth groove is provided on the outer wall of the driving ring 8. Since the extension tube 3 is inclined, the tooth surface of the tooth groove is perpendicular to the extension tube 3. The tooth groove is meshed 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. 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 meshed to ensure that the screw 81 is not affected by the gear rod 80 during rotation and can always rotate.

[0038] Secondly, a protrusion is provided on the outer wall of one of the end walls 34, and the screw rod 81 is threadedly penetrated through the protrusion and is 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 rod 81 can synchronously realize linear movement during the rotation process, and the screw rod 81 can be installed through the protrusion.

[0039] 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 supplemented 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.

[0040] Reference Figure 4 , Figure 5 , Figure 7 , Figure 8 and Fig. 9The 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 ​​the nutrients. When the material chamber 31 is in a closed state, the soil in the pool body 1 cannot pass through the lower surrounding wall. When the two movable arc walls 33 move in the opposite direction and are stored, and the middle sealing platform 32 moves upward, the original positions of the movable arc wall 33 and the middle sealing platform 32 are saved. After the nutrients enter this area, the nutrients are in the soil. Based on the linear movement of the middle sealing platform 32, the area below it can also be used for nutrients to enter, thereby increasing the contact surface between the nutrients and the soil; in addition, when the middle sealing platform 32 moves downward, the nutrients below it can be squeezed, thereby trying to achieve full infiltration of nutrients into the soil. At the same time, through the repeated linear movement of the middle sealing platform 32, the nutrients in the material chamber 31 can also be completely discharged to the outer wall of the material chamber 31 in the closed state.

[0041] 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: Method 1: Reference Fig.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 slideway 302. When the movable arc wall 33 is received in the arc slideway 302, the movable arc wall 33 contacts the horizontal end of the 7-shaped slide bar 320, thereby lifting the middle sealing platform 32 upward; 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 middle sealing platform 32 moves downward under the action of the return spring 321, 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, when 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 once, 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, it leaves free 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, it can be seen that the solid materials in the material chamber 31 are completely discharged.

[0042] Method 2: Reference Fig.11 and Fig.12In 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 toothed ring protrusion 324 and a limiting toothed ring protrusion 325 that mesh with the gear 323. The gear 323 is located between the driving toothed ring protrusion 324 and the limiting toothed ring protrusion 325. The initial state is referred to Fig.11 , the gear 323 does not contact the limiting toothed ring protrusion 325, and rotates with the moving arc wall 33 through the limiting toothed ring protrusion 325. The middle sealing platform 32 does not move after the gear 323 disengages from the limiting toothed ring protrusion 325, and the material chamber 31 is opened by the moving arc walls 33 on both sides; when the gear 323 contacts the driving toothed ring protrusion 324, the middle sealing platform 32 moves downward synchronously, thereby leaving the area below it empty to facilitate the entry of nutrients. Further, the two ends of the double-headed screw 322 are threadedly connected with a 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 is engaged with the driving toothed ring protrusion 324, it rotates through the moving arc wall 33 to realize the linear movement of the middle sealing platform 32.

[0043] Finally, it should be noted that: 1. The top of the middle sealing platform 32 is in an eight-shaped shape and corresponds to the bottom of the linear discharge port 301, so that the nutrients can flow evenly to the moving arc-shaped walls 33 on both sides. 2. The pulling method of the pull wire A6 and the pull wire B9 can be human pulling or electric pulling. Electric pulling can be achieved by motor winding, etc., which are all conventional technical means and are not recorded in detail.

[0044] The method of using the rice planting device is as follows: S1. Installation: Install the rice supply assembly in the pool body 1. The installation position of the rice supply assembly in the pool body 1 can be determined by the filling amount of the bottom soil; S2, filling soil: filling the pool 1 with soil until the soil covers the rice supply assembly; S3, nutrient supplement: through the delivery pipe 4, the nutrients in the supply ring 2 and the extension pipe 3 are supplemented; the delivery of solid nutrients, liquid nutrients or mixed nutrients can be controlled by pulling the pull wire A6; S4. Nutrients enter the soil: by pulling the pull wire B9, the material cavity 31 is opened, causing the nutrients to flow into the original lower wall area, so that the nutrients come into contact with the soil; when the nutrients in the material cavity 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 reciprocate up and down linear motion, and the middle sealing platform 32 moves upward to open the area below the middle sealing platform 32 to facilitate the inflow of nutrients; the middle sealing platform 32 moves downward to squeeze the nutrients in the area below the middle sealing platform 32.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
