Description

Technical Field

[0001] The present invention relates to the technical field of indica - japonica hybrid fertilizing devices, and specifically relates to a fertilizing device applicable to multiple stages of indica - japonica hybrids. Background Technique

[0002] Indica rice generally has a plant height of more than 1m, with relatively soft stems, wide leaves, a light green color, a small opening of the flag leaf, many leaf hairs, and short and small hairs scattered on the glume. Most are awnless or have short awns. The grains are slender and slightly flattened, generally with a length more than twice the width, and the grains are easy to fall off. It is more tolerant to moisture, heat, and strong light, but not cold - tolerant; Japonica rice has shorter stems, narrower leaves, a dark green color, short and thick grains, and the grains are not sticky. The grains of japonica rice are broad and short, thicker, oval or ovoid in shape, with high grain strength and good pressure resistance. It is not easy to produce broken rice during processing, and the milling rate is relatively high. The swelling property of the cooked rice is relatively small. Indica - japonica hybrid rice can achieve complementary advantages of strengths and weaknesses, and the plant type structure of the hybrid rice also has the supporting ability for super - high yield, and the yield increase is very obvious.

[0003] During the growth and development process of indica - japonica rice, fertilization needs to be carried out at different positions according to different growth periods. Dry fertilizer needs to be applied on the soil surface in the early stage, and topdressing is generally achieved by broadcasting. Existing fertilizing devices cannot simultaneously meet the requirements of ground fertilization and crop surface broadcasting. It still relies on manual labor to achieve the broadcasting requirement, increasing the manual labor intensity and prone to errors due to manual operation, resulting in uneven broadcasting, which in turn affects the growth and development quality of indica - japonica hybrid rice. Summary of the Invention

[0004] In view of the deficiencies existing in the existing fertilizing devices during use in the background technique, the present invention provides a fertilizing device applicable to multiple stages of indica - japonica hybrids, which has the advantage of being able to switch back and forth between ground fertilization and crop surface broadcasting, and solves the technical problems of low fertilization efficiency, large error, and poor adaptability of existing fertilizing devices mentioned in the above background technique.

[0005] The present invention provides the following technical solution: A fertilizing device applicable to multiple stages of indica - japonica hybrids, including a frame.

A clamping groove is provided at the top of the storage bin, which can also be movably clamped outside the frame. Discharge ports are symmetrically arranged at the bottom of the storage bin. A diversion pipe connected to the storage bin is configured outside the discharge port. A sealing plate is arranged outside the discharge port, and the sealing plate is movably connected to the outside of the storage bin through a spring. In the natural state, the sealing plate closes the discharge port.

[0008] Preferably, the limiting plate is connected to the rear side of the storage bin through a damping rotating shaft, and the limiting plate can coincide with the sealing plate through rotation. The limiting plate can fix the sealing plate at a position away from the discharge port of the storage bin.

[0009] Preferably, the bottom of the spreading cylinder is connected to the reciprocating swing motor on the frame, and a feed port is provided at the top of the spreading cylinder. The feed port can coincide with the bottom outlet of the pipeline when the spreading cylinder deflects. The feed port is communicated with the discharge port inside the spreading cylinder. A connecting rod is connected to the outside of the spreading cylinder through a hinge shaft. A torsion spring shaft is connected to the bottom of the connecting rod, and the spring shaft is connected to the hinge shaft on the outside of the spreading cylinder. The top of the connecting rod is in an inverted "U" shape, and the connecting rod can be clamped outside the connecting component and drive the connecting component to deflect.

[0010] Preferably, the discharge blades are symmetrically installed inside the storage bin near the bottom outlet through rotating shafts, and the rotating shafts of the discharge blades are connected to the connecting components outside the storage bin. The rotation of the connecting components can drive the rotation of the discharge blades, and multiple blade structures are arranged on the discharge blades.

[0011] Preferably, the movable plate is installed inside the storage bin through a torsion spring shaft, and the bottom of the movable plate coincides with the blades of the discharge blades. An extension plate is connected to the top of the movable plate. When the movable plate deflects, the extension plate also deflects. A bottom plate is connected to the top of the extension plate. The bottom plate covers the inner wall of the storage bin, and the left end of the bottom plate is connected to the inner wall of the storage bin through a hinge shaft. The rotation of the discharge blades can cause the movable plate to deflect and the bottom plate to tilt movably.

At the same time, by using the cooperation of the limiting plate, the storage tank can be fixed on the frame in two different directions, enabling the storage tank to adapt to the fertilization requirements of the indica-japonica hybrid rice at different stages, improving the adaptability and practicality of the device. And through the drawing of the connecting rod and the connecting component, the movement of the movable plate can be realized, thereby promoting the material inside the storage tank to approach the connecting pipe, achieving the effect of promoting the discharge of the material inside the storage tank, avoiding the problem that the material at the bottom of the storage tank accumulates and cannot be discharged from the pipeline, ensuring the smooth operation of the fertilizing device in different working modes, and also improving its working efficiency and quality.

[0015] 3.

Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-3 , a fertilizing device applicable to indica-japonica hybridization in multiple stages. The fertilizing device includes a frame 1. A handle is connected to the rear side of the frame 1 to facilitate the user to move the device. A driving wheel 7 is installed on the rear side of the frame 1, and a driven wheel 10 is installed on the front side of the frame 1. The driving wheel 7 is controlled to rotate by a driving motor on the frame 1. The operation of the driving motor on the driving wheel 7 is controlled through the handle on the frame 1. And a rechargeable battery is configured on the frame 1, which can provide corresponding electric energy for the driving of the driving motor on the driving wheel 7 and the spreading cylinder 3. The actions such as the motor driving the roller to rotate are prior art and will not be elaborated here; A storage bin 2 is movably inserted into the frame 1. The side of the storage bin 2 is provided with an inlet closed by two pistons up and down, which can facilitate the addition of fertilizer when the storage bin 2 is used in different directions. The storage bin 2 is in an "H" shape, and discharge ports are symmetrically opened at the bottom of the storage bin 2. The outside of the discharge port is connected with a diversion pipe 23. When the diversion pipe 23 faces the ground, its bottom end is close to the soil, which can facilitate the fertilizer to fall on the soil. Please refer to Figure 6, above the diversion pipe 23, a connecting component 21 installed outside the storage bin 2 is arranged. The inside of the connecting component 21 is connected to the discharge blade 9 installed inside the storage bin 2. The discharge blade 9 is movably connected through a rotating shaft, and when the connecting component 21 rotates, it can drive the rotation of the discharge blade 9. Symmetrically connected to the outside of the central rotating shaft of the driving wheel 7 are connecting blocks 71. The connecting component 21 is of a "U" - shaped structure, and when the storage bin 2 is sleeved outside the frame 1, the connecting component 21 is movably inserted outside the connecting blocks 71, so that when the driving wheel 7 rotates, it can drive the connecting component 21 to rotate, thereby enabling the discharge blade 9 to also rotate, realizing the function of automatic feeding, and making the fertilizer discharge speed of the storage bin 2 correspond to the moving speed of the device, ensuring the working efficiency and quality of the fertilizing device, and thus ensuring the growth quality of indica - japonica hybrid rice; Please refer to Figure 5 , inside the storage bin 2, a movable plate 8 is installed through a torsion spring shaft. The bottom end of the movable plate 8 coincides with a part of the blade of the discharge blade 9, so that when the discharge blade 9 rotates, it can drive the periodic reciprocating deflection of the movable plate 8, thereby promoting the mixing and movement of the materials inside the storage bin 2, avoiding problems such as fertilizer jamming or caking, and being able to promote the discharge of fertilizer from the discharge blade 9, ensuring the working efficiency of the fertilizing device.

[0020] Please refer to Figure 2, a clamping groove 24 is formed at the top of the storage bin 2. A limiting plate 5 is connected to the frame 1 through a torsion spring shaft. In the natural state, the limiting plate 5 is clamped in the clamping groove 24 to limit the position of the storage bin 2. At the same time, the storage bin 2 is turned 180 degrees so that the clamping groove 24 is clamped outside the frame 1, and the limiting plate 5 is also clamped at the other end of the storage bin 2 to fix the position of the storage bin 2, ensuring the position stability of the storage bin 2 during the operation of the device. At the same time, an opening sealed by a spiral cover is formed on the front side of the storage bin 2. After the storage bin 2 is turned over, the opening is located at the bottom of the storage bin 2 and is connected to the connecting pipe 41 through threads. The pipeline 4 is located on the front side of the frame 1, and the top of the pipeline 4 is connected to the connecting pipe 41. The pipeline 4 is of an inclined structure, and the bottom outlet of the pipeline 4 contacts the top surface of the spreading cylinder 3. The spreading cylinder 3 is installed on the front side of the frame 1, and the bottom of the spreading cylinder 3 is connected to and driven by a reciprocating swing motor installed on the frame 1, so that the operation of the spreading cylinder 3 can be controlled through a switch on the frame 1. The spreading cylinder 3 is driven at the bottom to achieve periodic reciprocating deflection. An inlet 33 is formed at the top of the spreading cylinder 3, and a discharge port 32 is arranged inside the spreading cylinder 3. When the spreading cylinder 3 deflects, the inlet 33 coincides with the bottom outlet of the pipeline 4, so that the fertilizer in the storage bin 2 can enter the discharge port 32 through the inlet 33. The fertilizer in the discharge port 32 is scattered out of the spreading cylinder 3 under the action of the inertia of the spreading cylinder 3, realizing the function of fertilizer spreading, enabling the fertilizing device to adapt to the fertilizing requirements of indica-japonica hybrid rice at different growth stages, saving labor, and also improving the uniformity and working efficiency of fertilizer spreading, thus avoiding the problem of uneven manual spreading and improving the growth quality of indica-japonica hybrid rice.

[0021] Please refer to Figure 2 , a connecting rod 31 is connected to the outside of the spreading cylinder 3 through a rotating shaft. The bottom end of the connecting rod 31 is simultaneously connected through a torsion spring shaft, and the bottom of the torsion spring shaft is connected to the bottom of the spreading cylinder 3 through a rotating shaft, so that the connecting rod 31 can be driven when the spreading cylinder 3 deflects. The top end of the connecting rod 31 is of an inverted "U" - shaped structure. The connecting rod 31 can be clamped outside the connecting component 21 through deflection, so that the connecting component 21 can be driven to deflect periodically reciprocally when the spreading cylinder 3 deflects. The movable plate 8 inside the storage bin 2 contacts the discharge blade 9 when the connecting component 21 and the connecting rod 31 are clamped, so that the movable plate 8 can be driven to deflect when the connecting rod 31 deflects. Please refer to Figure 4, one end of the movable plate 8 close to the pipeline 4 is provided with an extension plate 81. The extension plate 81 reciprocates and deflects as the movable plate 8 moves. The outer end of the extension plate 81 is connected to a bottom plate 811 through a rotating shaft, and the bottom of the bottom plate 811 is connected to the inner wall of the storage tank 2 through a rotating shaft. Therefore, when the storage tank 2 is connected to the pipeline 4, the bottom plate 811 is located at the bottom of the storage tank 2. Driving the connecting component 21 to reciprocate and deflect through the connecting rod 31 can realize the movement of the bottom plate 811, so that the bottom plate 811 can realize tilting movement, promoting the fertilizer at the bottom of the storage tank 2 to approach the pipeline 4, avoiding the problem that the fertilizer accumulates in the horizontal state and is not easy to be discharged from the pipeline 4, and being able to promote the discharge of the fertilizer, which is convenient for manual use.

[0022] Please refer to Figures 2-6 , a sealing plate 22 is arranged at the outlet at the bottom of the storage tank 2. The sealing plate 22 is movably connected to the outside of the storage tank 2 through a spring. In the natural state, the sealing plate 22 seals the outlet at the bottom of the storage tank 2, which is convenient for the movement or storage of the device. A clamping block 6 is connected to the outside of the storage tank 2 through a damping rotating shaft. The clamping block 6 can coincide with the sealing plate 22 through rotation, and the sealing plate 22 can be clamped outside the clamping block 6 to open the main outlet of the diversion pipe 23, thus facilitating the discharge of the fertilizer and providing convenience for the user.

[0023] The working principle of the usage method of the present invention is as follows: Charge the device and move it to the working area. When applying fertilizer to the ground, deflect the limit plate 5 and make the guide pipe 23 close to the ground, then insert the storage box 2 onto the frame 1. At the same time, make the connecting block 71 in a vertical state, rotate the connecting component 21 so that its opening faces downward. When the storage box 2 is clamped and installed on the frame 1, the connecting component 21 is sleeved outside the connecting block 71. Then release the limit plate 5, and the limit plate 5 is clamped on the clamping groove 24 to fix the position of the storage box 2. Pour the corresponding fertilizer into the inlet on one side of the storage box 2, and then close the inlet of the storage box 2. After the device moves to the working area, pull the sealing plate 22 outwards and rotate the clamping block 6 until they coincide, so that the sealing plate 22 is clamped by the clamping block 6. At this time, the bottom outlet of the storage box 2 is exposed. Control the driving motor on the driving wheel 7 to start working through the switch on the handle of the frame 1, so that the driving wheel 7 rotates and drives the device to move forward. The rotation of the driving wheel 7 makes the connecting block 71 rotate, and the rotation of the connecting block 71 drives the discharging blades 9 to rotate. The rotation of the discharging blades 9 makes the fertilizer inside the storage box 2 fall onto the soil along the guide pipe 23, achieving the effect of surface fertilization. At the same time, when the discharging blades 9 rotate, each blade passes through the movable plate 8, and the movable plate 8 makes periodic deflection movements, so that the granular fertilizer inside the storage box 2 will not get stuck and promotes the discharge of the fertilizer; when topdressing is required for indica-japonica hybrid rice in the later stage and broadcasting is needed, pull the limit plate 5 outwards and make it leave the storage box 2, turn the storage box 2 180 degrees, so that the guide pipe 23 is at the top. Then connect the connecting pipe 41 to the corresponding outlet on the storage box 2, so that the fertilizer inside the storage box 2 can enter the pipe 4 under the action of gravity through the connecting pipe 41. At this time, the bottom of the pipe 4 is closed by the top of the broadcasting cylinder 3. Rotate the connecting component 21 so that its opening faces upward, and at the same time move the movable connecting rod 31 and make the connecting rod 31 sleeved outside the connecting component 21. At this time, the discharging blades 9 connected inside the connecting component 21 also rotate and contact the movable plate 8. Start the device through the button on the handle of the frame 1, the driving wheel 7 is driven to rotate and makes the device move forward. The reciprocating swing motor at the bottom of the broadcasting cylinder 3 starts to work and drives the broadcasting cylinder 3 to make periodic reciprocating deflections. When the broadcasting cylinder 3 deflects to make the feeding port 33 dock with the bottom outlet of the pipe 4, the fertilizer inside the pipe 4 enters the discharging port 32. Then the broadcasting cylinder 3 deflects again and makes the fertilizer inside the discharging port 32 be scattered out of the discharging port 32 by means of external forces such as inertia, realizing the automatic broadcasting of the fertilizer. When the broadcasting cylinder 3 deflects, it drives the connecting rod 31 to move. The deflection of the connecting rod 31 makes the connecting component 21 also deflect. The connecting component 21 drives the discharging blades 9 inside the storage box 2 to deflect, and the movable plate 8 in contact with the discharging blades 9 makes reciprocating movements. When the movable plate 8 moves, the extension plate 81 drives the bottom plate 811 to make periodic deflections, so that the fertilizer on the bottom plate 811 can approach the connecting pipe 41, achieving the effect of promoting the discharge of materials; after use, move the device to the corresponding storage area, and regularly charge the energy storage component on the frame 1.
