Description

Technical Field

[0001] This utility model relates to the field of soybean planting equipment technology, specifically to an integrated soybean planting and fertilization machine. Background Technology

[0002] Soybeans are cultivated throughout China and are one of the country's important food crops. They have a cultivation history of 5,000 years and are a crop whose seeds are rich in plant protein. Sowing and fertilization are necessary to ensure the yield and quality of soybeans.

[0003] In current soybean planting operations, sowing and fertilization are carried out separately, requiring workers to move back and forth across the field, resulting in low overall efficiency. Currently, combined fertilization and sowing machinery is being used to replace this traditional planting method. However, due to the large size and weight of these combined machinery, they incur high purchase and maintenance costs. For small plots of land, the sowing efficiency is also limited by the planting area. Furthermore, when using combined agricultural machinery, it is impossible to observe the sowing and fertilization situation in a timely manner. If fertilizer and seeds are sown simultaneously in the same planting hole, it may lead to seedling burn.

[0004] To address the aforementioned issues, a soybean planting and fertilization integrated machine is proposed that does not rely on large machinery, is easy to operate, and allows for real-time monitoring of the planting situation. Utility Model Content

[0064] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0065] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0066] refer to Figures 1 to 11 A soybean planting and fertilizing integrated machine includes an outer cylinder 1, a seed storage tank 15, a first movable cylinder 7, an upper baffle ring 5, a top cover 4, a second movable cylinder 11, a lower baffle plate 9, a fertilizer tank 8, a seeding tube 1101, a fixing block 101, a fixing rod 2, a handrail 3, an operating mechanism, a feeding mechanism, and a fertilizing mechanism.

[0067] Fixing blocks 101 are fixedly installed on the left and right side walls of the outer cylinder 1, and the first ends of fixing rods 2 are fixedly installed on the outer sides of the two fixing blocks 101 respectively.

[0068] A handrail 3 is fixedly installed between the second ends of the two fixed rods 2. The handrail 3 is installed above the outer cylinder 1. The handrail 3 is used to facilitate the user to apply downward force to the equipment and to drive the operating mechanism described later to start working on the seeding tube by pressing down.

[0069] Therefore, a second movable cylinder 11 is movably installed inside the outer cylinder 1. A lower baffle 9 is fixedly installed at the lower end of the second movable cylinder 11. The lower baffle 9 is detachably in contact with the bottom wall of the outer cylinder 1. A seeding tube 1101 is connected to the lower end of the lower baffle 9. The seeding tube 1101 is connected to the second movable cylinder 11.

[0070] The seeding tube 1101 is driven by an operating mechanism. The seeding tube 1101 can be driven by the operating mechanism by the user's force. After the seeding tube 1101 is inserted into the soil, the seeds located in the seed storage tank 15 described later can be introduced into the second movable cylinder 11 through the feeding mechanism described later and finally enter the seeding tube 1101 to realize the sowing work.

[0071] A seed storage bin 15 is installed above the second movable cylinder 11. The seed storage bin 15 is movably installed inside the outer cylinder 1. A feeding mechanism is installed between the seed storage bin 15 and the second movable cylinder 11. The seed storage bin 15 is used to store soybean seeds to be sown. The seed storage bin 15 can move synchronously with the second movable cylinder 11 inside the outer cylinder 1. The second movable cylinder 11 can move synchronously with the sowing tube 1101. When the seed storage bin 15 and the second movable cylinder 11 move inside the outer cylinder 1, the feeding mechanism can be driven.

[0072] The upper end of the seed storage tank 15 is equipped with a first movable cylinder 7, and the upper end of the first movable cylinder 7 is equipped with an upper retaining ring 5. The upper retaining ring 5 is detachably in contact with the top wall of the outer cylinder 1. The upper end of the upper retaining ring 5 is rotatably equipped with a top cover 4. The top cover 4 is movably installed below the handle 3. The top cover 4 is used to seal the upper retaining ring 5 so that the upper end of the upper retaining ring 5 can be sealed, preventing external air from entering the seed storage tank 15 through the upper retaining ring 5 and causing the seeds to become damp and moldy. When the top cover 4 is opened, soybean seeds can also be added to the seed storage tank 15.

[0073] A fertilizer tank 8 is fixedly installed on the lower side wall of the outer cylinder 1, and a fertilizer application mechanism is installed inside the fertilizer tank 8.

[0074] The lower baffle 9 drives the fertilization mechanism to work. The fertilizer tank 8 is used to store solid fertilizers, such as urea crystals. The fertilizer inside will be discharged through the fertilization mechanism and fall near the sowing site as the lower baffle 9 moves, so as to fertilize the soil and avoid direct contact with soybean seeds.

[0075] The operating mechanism includes a first guide rod 901, a return spring 10, and a second guide rod 501;

[0076] Four second guide rods 501 are installed at equal angles at the lower end of the upper retaining ring 5. The outer cylinder 1 is provided with four round holes that cooperate with the second guide rods 501. The four second guide rods 501 are slidably installed in the round holes close to them.

[0077] Four first guide rods 901 are installed at equal angles on the upper end of the lower baffle 9, and the four first guide rods 901 are slidably installed in the circular holes close to them.

[0078] Four second guide rods 501 are respectively installed above the first guide rod 901 that is close to them;

[0079] A return spring 10 is respectively fitted on the outer wall of the four first guide rods 901. The head and tail ends of the four return springs 10 are respectively connected to the upper end of the lower baffle 9 and the lower end of the bottom wall of the outer cylinder 1.

[0080] The second movable cylinder 11 operates by driving the feeding mechanism.

[0081] The second movable cylinder 11 is equipped with a first inner cylinder 17, which is fixedly installed on the upper end of the bottom wall of the lower baffle plate 9. The first inner cylinder 17 is connected to the seeding tube 1101.

[0082] The inner wall of the first inner barrel 17 is a sloping wall to facilitate material guiding, see reference. Figure 2 , Figure 4 When the user holds the handle 3 and aligns the seeding tube 1101 at the bottom of the device with the seeding point, the device is pressed down. After the seeding tube 1101 is pressed into the soil, the four first guide rods 901 begin to slide upward in the circular holes close to them. During this process, the four return springs 10 are compressed. When the seeding tube 1101 is fully inserted into the soil, the lower baffle 9 begins to contact the soil. As the device is pressed down, the four return springs 10 are continuously compressed until the lower baffle 9 contacts the bottom wall of the outer cylinder 1. At this point, the return springs 10 are fully compressed. As the user lifts the device, the four return springs 10 will slowly begin to return to their original position. When the seeding tube 1101 is removed from the soil, the four return springs 10 are fully returned to their original position. During the movement of the lower baffle 9, the feeding mechanism described later will begin to drive the device.

[0083] The feeding mechanism includes a rotating cylinder 14 and a slider 1401;

[0084] The upper end of the second movable cylinder 11 is rotatably mounted with a rotating cylinder 14, which is rotatably mounted at the lower end of the seed storage tank 15. The rotating cylinder 14 is provided with several seed outlet holes 1402.

[0085] The lower end of the seed storage tank 15 is provided with a feeding hole 1501, and a number of seed outlet holes 1402 are detachably connected to the feeding hole 1501.

[0086] A slider 1401 is installed on the side wall of the rotating cylinder 14;

[0087] The inner wall of the outer cylinder 1 is provided with a spiral groove 102 that cooperates with the slider 1401. The slider 1401 is slidably installed in the spiral groove 102. When the lower baffle 9 moves below the outer cylinder 1, it will drive the second movable cylinder 11 fixed thereto to move up and down synchronously. (See reference) Figure 4 As the second movable barrel 11 moves upward, it drives the rotating barrel 14 located above it to also move upward. The slider 1401 on the side wall of the rotating barrel 14 also begins to slide upward. However, since the movement trajectory of the slider 1401 is confined within the spiral groove 102, the slider 1401 begins to spiral upward along the spiral groove 102. During this process, the rotating barrel 14, fixed to the slider 1401, also gains rotational ability as it moves upward. As the rotating barrel 14 rotates, it gradually causes the several seed outlet holes 1401 and the storage holes at its lower end to... The feeding holes 1501 at the lower end of the seed barrel 15 are connected. At this time, the soybean seeds in the seed storage barrel 15 can enter the second movable barrel 11 through this connected space and enter the sowing tube 1101 through the inclined wall of the first inner barrel 17. It should be noted that since the movement trajectory of the first movable barrel 7 located at the upper end of the rotating barrel 14 is limited by the four second guide rods 501, the first movable barrel 7 will not be driven to rotate by the rotating barrel 14. Therefore, it is possible to achieve a connection between the several seed outlet holes 1402 and the feeding holes 1501 as the rotating barrel 14 rotates.

[0088] The fertilization mechanism includes a movable rod 12, an extension plate 902, and a second inner bucket 13;

[0089] A second inner barrel 13 is installed inside the fertilizer barrel 8. The bottom wall of the second inner barrel 13 is provided with a cylindrical through hole 1302, and the upper end of the cylindrical through hole 1302 is provided with a frustum-shaped through hole 1301. The short sections of the cylindrical through hole 1302 and the frustum-shaped through hole 1301 are connected.

[0090] The same movable rod 12 is movably installed in both the cylindrical through hole 1302 and the frustum-shaped through hole 1301;

[0091] A circular baffle 1201 is fixedly installed at the upper end of the movable rod 12, and the circular baffle 1201 can be detachably installed in the cylindrical through hole 1302;

[0092] An extension plate 902 is fixedly installed on one side of the lower baffle 9 near the fertilizer tank 8. The lower end of the movable rod 12 is fixedly connected to the extension plate 902. When the lower baffle 9 moves towards the bottom wall of the outer cylinder 1, the extension plate 902 fixedly installed thereon will move synchronously towards the bottom wall of the outer cylinder 1 along with the lower baffle 9. Therefore, the movable rod 12 fixedly installed thereon begins to move upward. (Refer to...) Figure 11 Since the fertilizer tank 8 and the outer cylinder 1 are fixed, the fertilizer tank 8 will not move during the upward movement of the movable rod 12. When the equipment is in the initial state, the movable rod 12 is at the bottom and the circular baffle 1201 is at the bottom inside the cylindrical through hole 1302. When the movable rod 12 starts to move upward, the circular baffle 1201 gradually slides upward along the cylindrical through hole 1302 and eventually completely detaches from the cylindrical through hole 1302. At this time, a connecting space can be formed between the cylindrical through hole 1302 and the frustum-shaped through hole 1301. The solid fertilizer in the fertilizer tank 8 can then pass through this connecting space and fall from the bottom of the cylindrical through hole 1302 to the vicinity of the sowing site. When the movable rod 12 moves downward, the circular baffle 1201 will begin to slide into the cylindrical through hole 1302 to block the connecting space.

[0093] A drive motor 6 is installed at the upper end of the top cover 4. The output shaft of the drive motor 6 rotates through the top cover 4 and a fan blade 16 is fixedly installed thereon.

[0094] A protective shell 401 is installed at the lower end of the top cover 4. The protective shell 401 and the inner wall of the upper baffle ring 5 are in detachable contact. The fan blade 16 is movably installed inside the protective shell 401.

[0095] The bottom wall of the protective shell 401 is provided with several first air outlets 4011;

[0096] Several second air outlets 701 are installed on the side wall of the first movable cylinder 7. Since the seeds in the seed storage tank 15 may be damp during storage, the seeds in the seed storage tank 15 can be dried by controlling the drive motor 6. The output shaft of the drive motor 6 will drive the fan blade 16 installed on the same axis to start rotating. The air driven by the fan blade 16 will enter the first movable cylinder 7 through the first air outlet 4011. The lower end of the first movable cylinder 7 is connected to the top wall of the seed storage tank 15. Therefore, the air will enter the seed storage tank 15 through the first movable cylinder 7 and be discharged through the several second air outlets 701 to achieve drying. Preferably, the switch of the drive motor can be installed on the handrail 3 for the user to control and stop it at any time.

[0097] The implementation method of this utility model:

[0098] Flip the top cover 4 upwards and put the soybean seeds to be sown into the first movable cylinder 7 through the upper retaining ring 5. The seeds will then enter the seed storage tank 15 through the first movable cylinder 7 to begin storage.

[0099] Solid fertilizer is loaded into fertilizer tank 8. A sealing cap is detachably provided on the top wall of fertilizer tank 8. The sealing cap and fertilizer tank 8 are connected by a threaded connection.

[0100] After the user holds the device to the target sowing location, they align the lower sowing tube 1101 with the sowing location and press the device downwards with the handle 3. At this time, the sowing tube 1101 is inserted into the soil. Simultaneously, the rotating cylinder 14 inside the outer cylinder 1 begins to rotate. When the sowing tube 1101 is fully inserted into the soil, the rotating cylinder 14 rotates to a state where a communication space is formed between several seed outlet holes 1402 and material discharge holes 1501. At this time, the soybean seeds in the seed storage tank 15 will enter the sowing tube 1101 through this communication space and fall into the inserted sowing hole through the sowing tube 1101.

[0101] During the process of inserting the seeding tube 1101 into the soil, the lower retaining ring 9 will move towards the bottom wall of the outer cylinder 1. At this time, the movable rod 12, which is fixedly installed with the expansion plate 902, begins to move upward inside the fertilizer tank 8. As the movable rod 12 moves upward, the circular baffle 1201 will gradually disengage from the cylindrical through hole 1302, so that the cylindrical through hole 1302, the frustum-shaped through hole 1301 and the inner cavity of the fertilizer tank 8 are connected. At this time, the solid fertilizer located in the inner cavity of the fertilizer tank 8 will fall into the vicinity of the sowing site through the frustum-shaped through hole 1301 and the cylindrical through hole 1302, thereby achieving the function of fertilizing the soil.

[0102] When the first movable cylinder 7 slides out above the outer cylinder 1, the user can start the drive motor 6 to drive the fan blade 16 to start rotating, thereby drying the soybean seeds in the seed storage tank 8 and preventing the seeds from becoming moldy and necrotic due to moisture.

[0103] This invention allows the sowing tube to be inserted into the soil at a preset sowing depth using a handheld pressing device. After insertion, the feeding mechanism will drive the feeding mechanism to deliver soybean seeds into the sowing tube and into the soil. At the same time, the fertilization mechanism will start to apply fertilizer. The fertilizer is applied near the sowing location rather than in direct contact with the seeds, thus avoiding the consequences of burning the seedlings.

[0104] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
