Description

Technical Field

[0001] This invention relates to the field of rice seedling cultivation technology, and in particular to a fertilizer applicator for rice seedling cultivation. Background Technology

[0002] Rice is a herbaceous plant belonging to the genus Oryza, and it is the most important and oldest food crop in the Oryza genus. Due to my country's large population, the demand for food is particularly high. Among the many grains, rice has the largest demand in my country. Therefore, rice production is closely related to the basic livelihood of the Chinese people. Currently, many agricultural experiments in my country are being conducted on how to increase rice yield.

[0003] Currently, there are two methods for rice seedling cultivation in the laboratory: hydroponics and soil cultivation. When hydroponically fertilizing the seedlings, different amounts of the same fertilizer have different effects on the rice seedlings. It is necessary to conduct comparative experiments on the production of rice seedlings and observe the production of the seedlings over a certain period of time to determine the maximum amount of the same fertilizer for seedling production. Existing fertilizer applicators used for rice seedling cultivation have the problem of poor fertilizer dispersion during use. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fertilizer applicator for rice seedling cultivation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fertilizer applicator for rice seedling cultivation includes a movable base with support legs mounted at each of the four corners of its bottom. Each support leg has a movable wheel at its bottom. A storage housing is mounted on the top of the movable base, and a rotating seat is movably mounted inside the storage housing at its bottom. The rotating seat has a second through hole at its top. A first through hole is also present on the top of the movable base, and an extension tube is mounted on the bottom of the movable base. The top opening of the extension tube corresponds to the bottom opening of the first through hole. The opening of the second through hole corresponds to the opening of the first through hole. The applicator also includes a first drive mechanism. The component is used to drive the rotating seat to rotate horizontally; a horizontally arranged second mounting seat is installed at the bottom of the inner wall of the storage shell, the bottom of the second mounting seat abuts against the top of the rotating seat, and the hollow position at the bottom of the second mounting seat corresponds to the center position at the top of the rotating seat; a cavity is opened inside the second mounting seat, and an air outlet is opened on the side of the cavity near the rotating seat, and the opening position of the air outlet corresponds to the opening position of the first through hole; it also includes an air pump, and a second extended air pipe is provided at the air outlet end of the air pump, and the end of the second extended air pipe away from the air pump is connected to the interior of the cavity.

[0007] Preferably, the inner wall of the extension tube is equipped with annular buffer airbags at intervals to buffer the fertilizer falling inside the extension tube; the inner diameter of the top opening of the buffer airbag is larger than the inner diameter of the bottom opening of the buffer airbag.

[0008] Preferably, the second extension air pipe is equipped with the first extension air pipe; the second extension air pipe is provided with a control valve for controlling the airflow flowing in the second extension air pipe.

[0009] Preferably, the outer circumferential wall of the buffer airbag is provided with a third perforation, and the inner diameter of the opening of the third perforation is smaller than the inner diameter of the first extension air tube.

[0010] Preferably, the storage shell is provided with an agitation mechanism for agitating the fertilizer inside the storage shell.

[0011] Preferably, the agitation mechanism includes a fixed base installed inside the storage shell, a first mounting base movably mounted on the bottom of the fixed base, and an agitation component mounted on the bottom of the first mounting base; it also includes a second driving component for driving the first mounting base to rotate.

[0012] Preferably, the circumference of the rotating seat is slidably connected to the inner circumference of the storage shell.

[0013] The beneficial effects of this invention are as follows:

[0014] In use, the movable seat is pushed to move horizontally on the rice seedling raising equipment. At the same time, the first drive component drives the rotating seat to rotate horizontally inside the storage shell. The fertilizer stored in the storage shell falls into the second perforation. When the opening of the second perforation moves with the rotation of the rotating seat to align with the opening of the first perforation, the second mounting seat blocks the opening of the second perforation located at the top of the opening of the first perforation. The fertilizer in the second perforation falls into the first perforation and finally falls into the extension tube and is applied to the seedling raising equipment to achieve fertilization. When the opening of the second perforation moves to align with the opening of the first perforation, the air pump blows air into the cavity through the second extension air tube. The airflow is sprayed out from the air outlet to blow air into the fertilizer in the openings of the second and first perforations, preventing the fertilizer from being blocked or stagnant in the second or first perforation, and ensuring effective fertilization.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In one embodiment, refer to Figures 1 to 4 A fertilizer applicator for rice seedling cultivation includes a movable base 1, with support legs 2 installed at each of the four corners of the bottom of the movable base 1. Each support leg 2 has a movable wheel 3 at its bottom. A storage shell 11 is installed on the top of the movable base 1, and a rotating seat 9 is movably installed inside the bottom of the storage shell 11. The top of the rotating seat 9 has a second through hole 7. A first through hole 4 is opened on the top of the movable base 1, and an extension tube 5 is installed at the bottom of the movable base 1. The top opening of the extension tube 5 corresponds to the bottom opening of the first through hole 4. The opening of the second through hole 7 corresponds to the opening of the first through hole 4. It also includes a first driving component 8 for driving... The rotating seat 9 rotates horizontally; a horizontally arranged second mounting seat 12 is installed at the bottom of the inner wall of the storage shell 11, the bottom of the second mounting seat 12 abuts against the top of the rotating seat 9, and the hollow position at the bottom of the second mounting seat 12 corresponds to the center position at the top of the rotating seat 9; a cavity 14 is opened inside the second mounting seat 12, and an air outlet 15 is opened on the side of the cavity 14 near the rotating seat 9, and the opening position of the air outlet 15 corresponds to the opening position of the first through hole 4; it also includes an air pump 13, and a second extended air pipe 17 is provided at the air outlet end of the air pump 13, and the end of the second extended air pipe 17 away from the air pump 13 is connected to the interior of the cavity 14.

[0022] During use, the movable seat 1 is pushed to move horizontally on the rice seedling raising equipment. At the same time, the first driving component 8 drives the rotating seat 9 to rotate horizontally inside the storage shell 11. The fertilizer stored in the storage shell 11 falls into the second perforation 7. When the opening of the second perforation 7 moves with the rotation of the rotating seat 9 to align with the opening of the first perforation 4, the second mounting seat 12 blocks the opening of the second perforation 7 located at the top of the opening of the first perforation 4. The fertilizer in the second perforation 7 falls into the first perforation 4 and finally falls into the extension tube 5 and is applied to the seedling raising equipment to achieve fertilization. When the opening of the second perforation 7 moves to align with the opening of the first perforation 4, the air pump 13 blows air into the cavity 14 through the second extension air tube 17. The airflow is sprayed out from the air outlet 15 to blow air into the fertilizer in the openings of the second perforation 7 and the first perforation 4, so as to avoid the fertilizer from being blocked or stuck in the openings of the second perforation 7 or the first perforation 4, and to ensure the effective fertilization.

[0023] In a preferred embodiment of the present invention, the first driving component 8 is an electric slide rail with a ring structure.

[0024] In a preferred embodiment of the present invention, annular buffer airbags 6 are installed at intervals on the inner wall of the extension tube 5 to buffer the fertilizer falling inside the extension tube 5; the inner diameter of the top opening of the buffer airbag 6 is larger than the inner diameter of the bottom opening of the buffer airbag 6.

[0025] In a preferred embodiment of the present invention, the buffer airbag 6 is made of materials such as rubber and silicone. In this embodiment, the buffer airbag 6 is preferably made of rubber.

[0026] In a preferred embodiment of the present invention, a first extension air pipe 16 is installed on the second extension air pipe 17; a control valve 18 is provided on the second extension air pipe 17 for controlling the airflow flowing inside the second extension air pipe 17.

[0027] In a preferred embodiment of the present invention, a third perforation is provided on the outer circumferential wall of the cushioning airbag 6. The inner diameter of the opening of the third perforation is smaller than the inner diameter of the first extended air tube 16. During use, as the rotating seat 9 rotates, when the top opening of the second perforation 7 aligns with the opening of the air outlet 15, the airflow in the cavity 14 flows through the air outlet 15 into the second perforation 7. When the opening of the second perforation 7 and the opening of the air outlet 15 are misaligned, the top of the rotating seat 9 blocks the opening of the air outlet 15. At this time, the control valve 18 controls the airflow in the second extended air tube 17, causing the air in the second extended air tube 17 to stop flowing into the cavity 14. The air in the second extended air tube 17 is then sprayed into the cushioning airbag 6 through the first extended air tube 16. The air flow rate inside the air bladder 6 is much greater than the air flow rate from the third perforation, causing the air bladder 6 to inflate and expand. This intercepts and buffers the fertilizer falling through the extension tube 5, allowing the fertilizer to fall dispersedly from the bottom opening of the extension tube 5 into the seedling raising equipment. This prevents the fertilizer from falling into the same position on the seedling raising equipment, ensuring the dispersion effect of fertilization. When the opening of the second perforation 7 aligns with the opening of the air outlet 15 again, the control valve 18 controls the air in the second extension air tube 17 to stop flowing into the first extension air tube 16. At this time, the gas in the air bladder 6 is slowly released through the third perforation until the air bladder 6 returns to its uninflated state. This achieves the repeated inflation and deflation of the air bladder 6 during the fertilization process.

[0028] In one embodiment, refer to Figures 1 to 4 A fertilizer applicator for rice seedling cultivation includes a movable base 1, with support legs 2 installed at each of the four corners of the bottom of the movable base 1. Each support leg 2 has a movable wheel 3 at its bottom. A storage shell 11 is installed on the top of the movable base 1, and a rotating seat 9 is movably installed inside the bottom of the storage shell 11. The top of the rotating seat 9 has a second through hole 7. A first through hole 4 is opened on the top of the movable base 1, and an extension tube 5 is installed at the bottom of the movable base 1. The top opening of the extension tube 5 corresponds to the bottom opening of the first through hole 4. The opening of the second through hole 7 corresponds to the opening of the first through hole 4. It also includes a first driving component 8 for driving... The rotating seat 9 rotates horizontally; a horizontally arranged second mounting seat 12 is installed at the bottom of the inner wall of the storage shell 11, the bottom of the second mounting seat 12 abuts against the top of the rotating seat 9, and the hollow position at the bottom of the second mounting seat 12 corresponds to the center position at the top of the rotating seat 9; a cavity 14 is opened inside the second mounting seat 12, and an air outlet 15 is opened on the side of the cavity 14 near the rotating seat 9, and the opening position of the air outlet 15 corresponds to the opening position of the first through hole 4; it also includes an air pump 13, and a second extended air pipe 17 is provided at the air outlet end of the air pump 13, and the end of the second extended air pipe 17 away from the air pump 13 is connected to the interior of the cavity 14.

[0029] In a preferred embodiment of the present invention, a stirring mechanism 10 is provided inside the storage shell 11 for stirring the fertilizer inside the storage shell 11.

[0030] In a preferred embodiment of the present invention, the stirring mechanism 10 includes a fixed base 103 installed in the storage shell 11, a first mounting base 102 movably mounted on the bottom of the fixed base 103, and a stirring component 101 mounted on the bottom of the first mounting base 102; it also includes a second driving component 104 for driving the first mounting base 102 to rotate. The first mounting base 102 can be driven to rotate by the second driving component 104, thereby driving the stirring component 101 to stir and mix the fertilizer in the storage shell 11, ensuring uniform fertilization.

[0031] In a preferred embodiment of the present invention, the circumference of the rotating seat 9 is slidably connected to the inner circumference of the storage shell 11.

[0032] In use, the movable seat 1 is pushed to move horizontally on the rice seedling raising equipment. Simultaneously, the first driving component 8 drives the rotating seat 9 to rotate horizontally within the storage shell 11. The fertilizer stored in the storage shell 11 falls into the second perforation 7. When the opening of the second perforation 7 moves with the rotation of the rotating seat 9 to align with the opening of the first perforation 4, the second mounting seat 12 blocks the opening of the second perforation 7 located at the top of the opening of the first perforation 4. The fertilizer in the second perforation 7 falls into the first perforation 4, and finally into the extension tube 5 and is applied to the seedling raising equipment, thus achieving fertilization. The second perforation 7 moves to align with the opening of the first perforation 4. When the openings of perforations 4 are aligned, the air pump 13 blows air into the cavity 14 through the second extended air pipe 17, and the airflow is ejected from the air outlet 15, blowing air into the fertilizer in the openings of the second perforation 7 and the first perforation 4 to prevent fertilizer from clogging or remaining in the second perforation 7 or the opening of the first perforation 4, ensuring effective fertilization. During use, as the rotating seat 9 rotates, when the top opening of the second perforation 7 aligns with the opening of the air outlet 15, the airflow in the cavity 14 flows into the second perforation 7 through the air outlet 15. When the openings of the second perforation 7 and the air outlet 15 are misaligned, the top of the rotating seat 9 aligns with the air outlet 15. When the opening of extension tube 5 is blocked, control valve 18 controls the airflow in the second extension air pipe 17, causing the air in the second extension air pipe 17 to stop flowing into the cavity 14. The air in the second extension air pipe 17 is then sprayed into the buffer airbag 6 through the first extension air pipe 16. The airflow from the first extension air pipe 16 into the buffer airbag 6 is much greater than the airflow from the third perforation, causing the buffer airbag 6 to inflate and thus intercept and buffer the fertilizer falling from the extension pipe 5. This allows the fertilizer falling from the extension pipe 5 to fall dispersedly from the bottom opening of the extension pipe 5 into the seedling raising equipment, preventing the fertilizer falling from the extension pipe 5 from falling into the seedling raising equipment. The fertilizer is placed in the same position on the seedling raising equipment to ensure the dispersion effect of fertilizer application. When the opening of the second perforation 7 is aligned with the opening of the air outlet 15 again, the control valve 18 controls the air in the second extended air pipe 17 to stop flowing into the first extended air pipe 16. At this time, the gas in the buffer air bag 6 is slowly released through the third perforation until the buffer air bag 6 returns to the uninflated state. That is, during the fertilization process, the buffer air bag 6 is repeatedly inflated and deflated. The first mounting base 102 can be driven to rotate by the second drive component 104, which drives the stirring component 101 to stir and mix the fertilizer in the storage shell 11 to ensure uniform fertilization.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
