Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery, specifically relating to a portable no-till seeding device. Background Technology

[0002] Most existing seeding devices are electrically powered, which severely limits their use in remote farmland or field environments lacking a stable power supply. Furthermore, electrically powered equipment typically requires a power source or external power line, increasing the complexity and cost of use. In addition, many seeding devices are cumbersome to operate, requiring professional operators for debugging and control, making them difficult for ordinary farmers to learn and operate efficiently.

[0003] From the perspective of sowing results, some sowing equipment results in uneven seed distribution during sowing, affecting nutrient uptake and space utilization during crop growth, ultimately reducing crop yield. At the same time, these devices are generally bulky and complex in structure, which not only makes them expensive to manufacture, but also lacks flexibility in transportation and field operation, making them unable to adapt to the sowing needs of diverse terrains such as small fields, mountains, and slopes.

[0004] In view of the above problems, we need to develop a portable seeding device that can automatically sow seeds without electricity, is easy to operate, can accurately control the sowing interval, and is low in cost and small in size. Utility Model Content

[0033] Compared with the prior art, the beneficial effects of this utility model are:

[0034] 1. The overall structure of this utility model is ingenious, and the layout of the seeding wheel, support, pressing wheel, and control device is reasonable. The seeding wheel is located at the front end of the support and is movably connected to the bottom end of the support. The pressing wheel is located at the end of the support and is on the same horizontal line as the seeding wheel and is also movably connected to the bottom end of the support. This design ensures that the device can operate stably during the sowing process, making the series of actions such as furrowing, sowing, and pressing smooth and continuous.

[0035] 2. The planting wheel of this utility model has a ditching mechanism, a seed storage mechanism, a limiting mechanism, and an outlet that work together to enable precise and efficient planting. The ditching mechanism is located on the outside of the main body for breaking the soil and opening furrows. The seed storage mechanism is located inside the main body to store seeds. The outlet is connected to the seed storage mechanism to realize seed output. The limiting mechanism and control device work together to precisely control the timing and quantity of seed outflow. All parts work closely together to optimize the planting process.

[0036] 3. This utility model has a high degree of integration, modularly integrating the seed storage mechanism and the limiting mechanism into the utility model, thus eliminating the limitation of electricity and providing excellent portability; the seed storage mechanism has a scientifically designed seed inlet, seed storage bin, and barrier. The seed inlet facilitates the entry of seeds into the seed storage bin, while the barrier cleverly controls the flow of seeds to the outlet, ensuring the orderly storage and release of seeds. The limiting mechanism, through a combination of ground contact rod, limiting elastic element, and lever mechanism, automatically adjusts the restriction on seed outflow according to the undulation of the ground, achieving precise sowing and avoiding seed waste.

[0037] 4. The design of the control device of this utility model is highly user-friendly. The lever mechanism and the limiting mechanism work together. When the ground plane contacts the ground, the limiting elastic element is compressed, and the paddle moves downward. The seed falls from the seed storage bin into the seed channel through the narrow opening. At the same time, when the paddle moves downward, it squeezes the elastic contact piece of the outlet, so that the seed automatically falls into the pit opened by the blade through the outlet, realizing automatic sowing. The cooperation between the direct control unit and the connecting rod allows the operator to precisely control the action of the limiting mechanism in the sowing wheel through a series of transmissions by simply operating the pull ring, thereby flexibly adjusting the sowing interval.

[0060] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0061] Example 1:

[0062] like Figures 1-3As shown, a portable no-till seeding device in this embodiment includes a seeding wheel 1, a support 2, a pressing wheel 3, and a control device 4. The seeding wheel 1 is located at the front end of the support 2 and is movably connected to the bottom end of the support 2. The pressing wheel 3 is located at the end of the support 2 and is at the same horizontal level as the seeding wheel 1, ensuring that the pressing wheel 3 can cover the seeds sown by the seeding wheel 1 with soil. The pressing wheel 3 is movably connected to the bottom end of the support 2 and can be disassembled to ensure the portability of this seeding device.

[0063] The seeding reel 1 includes a main body 5, a furrowing mechanism 6, a seed storage mechanism 7, a restricting mechanism 8, and an outlet section 9;

[0064] The ditching mechanism 6 is located on the outside of the main body 5 and is connected to the main body 5, which can dig small furrows on the ground. The seed storage mechanism 7 is located inside the main body 5 and is connected to the main body 5, so that the overall sowing device does not occupy too much space. The outlet 9 is located on the outside of the seed storage mechanism 7 and is connected to the main body 5. The outlet 9 and the seed storage mechanism 7 are connected, so that the seeds stored in the seed storage mechanism 7 can be discharged from the inside of the main body 5 through the outlet 9. The limiting mechanism 8 is located between the outlet 9 and the outside of the main body 5. One end of the limiting mechanism 8 abuts against the seed storage mechanism 7 to control the connection between the seed storage mechanism 7 and the outlet 9. The other end of the limiting mechanism 8 is connected to the outside of the main body 5. When the end of the limiting mechanism 8 on the outside of the main body 5 touches the ground, the end of the limiting mechanism 8 inside the main body 5 will be displaced, thereby achieving the purpose of controlling the connection between the seed storage mechanism 7 and the outlet 9.

[0065] The control device 4 is located on the outside of the bracket 2, and one end of the control device 4 is connected to the limiting mechanism 8, and the other end of the control device 4 is connected to the top of the bracket 2. The control device 4 controls the displacement of the end of the limiting mechanism 8 located on the outside of the body 5, thereby controlling the connection between the internal seed storage mechanism 7 and the outlet 9.

[0066] like Figures 1-3 As shown, in this embodiment, the ditching mechanism 6 is a blade, and there are 5 ditching mechanisms 6, seed storage mechanisms 7, restricting mechanisms 8 and outlet parts 9. The positions of the 5 ditching mechanisms 6, seed storage mechanisms 7, restricting mechanisms 8 and outlet parts 9 are corresponding, so that the seeding wheel 1 can sow seeds in multiple places in one rotation.

[0067] like Figure 2 and Figure 3As shown, the seed storage mechanism 7 in this embodiment includes a seed inlet 71, a seed storage chamber 72, and a sluice gate 73. The seed inlet 71 is located on the outer surface of the seed storage chamber 72 and is connected to the seed storage chamber 72. The seed inlet 71 is in communication with the inside of the seed storage chamber 72, and seeds can be directly injected into the seed storage chamber 72 through the seed inlet 71. The sluice gate 73 is located inside the seed storage chamber 72 and is located between the seed storage chamber 72 and the outlet 9. The seed storage chamber 72 is in communication with the outlet 9 through the sluice gate 73. The setting of the sluice gate 73 can allow the limiting mechanism 8 to more accurately control whether the seeds enter the outlet 9 by whether the sluice gate 73 is closed or not.

[0068] Among them, such as Figure 4 As shown, the limiting mechanism 8 includes a ground rod 81, a limiting elastic element 82, and a lever mechanism 83; one end of the lever mechanism 83 is located inside the outlet 9 and abuts against the narrow passage 73, and the other end of the lever mechanism 83 is located outside the body 5 and abuts against the ground; the middle part of the lever mechanism 83 passes through the body 5, and the middle part of the lever mechanism 83 is connected to the body 5 by a pin, so that when one end of the lever mechanism 83 located outside the body 5 is moved, the end located inside the body 5 does not abut against the narrow passage 73;

[0069] The grounding rod 81 is located at one end of the lever mechanism 83 near the outer side of the main body 5, and the top end of the grounding rod 81 penetrates the main body 5. The top end of the grounding rod 81 is slidably connected to the inside of the main body 5, and the bottom end of the grounding rod 81 is connected to the end of the lever mechanism 83. The limiting elastic element 82 is located inside the grounding rod 81, and one end of the limiting elastic element 82 is connected to the outer side of the main body 5, while the other end of the limiting elastic element 82 is connected to the lever mechanism 83. The limiting elastic element 82 and the grounding rod 81 cooperate with each other so that when the grounding rod 81 is not in contact with the ground, the limiting elastic element 82 is in a relaxed state. The end of the lever mechanism 83 located inside the main body 5 can be directed upward under the action of the limiting elastic element 82, abutting against the obstruction 73. When the grounding rod 81 contacts the ground, the grounding rod 81 is squeezed and slides upward, causing the limiting elastic element 82 to be compressed. Then, the end of the lever mechanism 83 located inside the main body 5 moves downward and disengages from the obstruction 73, allowing the seeds in the seed storage bin 72 to fall into the outlet 9, realizing the purpose of automating the sowing by rolling the sowing wheel 1.

[0070] Specifically, the lever mechanism 83 includes a paddle 831, a rod 832, and a ground plane 833. The paddle 831 is located at the top of the rod 832 and abuts against the narrow passage 73. The shape of the paddle 831 is adapted to the narrow passage 73, thereby achieving the purpose of sealing the narrow passage 73. The ground plane 833 is located at the end of the rod 832 and abuts against the ground. The bottom of the ground plane 833 is flat, thereby achieving a larger contact area with the ground, making the force on the ground rod 81 more prominent and increasing its flexibility.

[0071] like Figure 4 As shown, the outlet 9 in this embodiment includes a seed channel 91, an outlet 92, and an elastic tab 93; the outlet 92 is disposed on the outer surface of the body 5 and is connected to the body 5 so that the seeds can fall into the outside.

[0072] The seed channel 91 is located between the outlet 92 and the pass 73, with one end of the seed channel 91 connected to the outlet 92 and the other end of the seed channel 91 connected to the pass 73, so that the seed is dropped from the pass 73 into the seed channel 91 by the pick 831.

[0073] It is particularly important to emphasize that the width of the narrow pass 73 directly affects the amount of seeds sown at one time. In this embodiment, the narrow pass 73 is modularly designed, with a width of 2cm, allowing for the sowing of 3 to 5 seeds at a time.

[0074] The elastic tab 93 is located on the outer side of the body 5 and is movably connected to the outlet 92. When the paddle 831 slides down, the elastic tab 93 will be pushed open by the downward force. At this time, the seeds that have just fallen into the seed channel 91 will continue to fall out from the outlet 92, and the seeding wheel 1 will continue to roll forward. After the elastic element 82 is restricted from being squeezed by the ground, it will return to the relaxed state, and the paddle 831 will return to the state of abutting the obstruction 73.

[0075] In addition, such as Figure 1 , Figure 2 and Figure 5 As shown, the control device 4 in this embodiment includes a direct control unit 41 and a connecting rod 42; the end of the direct control unit 41 is connected to the top of the connecting rod 42, the top of the direct control unit 41 is slidably connected to the top of the bracket 2, the connecting rod 42 is disposed inside the body 5, and the bottom end of the connecting rod 42 is connected to the grounding rod 81, that is, by controlling the connecting rod 42, the grounding rod 81 can be manually controlled, and due to the slidable design of the direct control unit 41, the connecting rod 42 can be controlled by directly controlling the direct control unit 41;

[0076] Among them, such as Figure 1As shown, the direct control unit 41 includes an inner cam 411, an outer cam plate 412, a wheel groove 413, a slider 414, a pull rod 415, a limiting mechanism 416, and a pull ring 417. The inner cam 411 is located on the outside of the seed storage mechanism 7 and is connected to the outer surface of the body 5. The outer cam plate 412 is located between the seed storage mechanism 7 and the outlet 9 and is elastically connected to the outer surface of the body 5. The bottom of the outer cam plate 412 is connected to the connecting rod 42. The wheel groove 413 is provided with... Between the outer cam plate 412 and the inner cam 411, the slider 414 engages with the wheel groove 413. The main function of the inner cam 411 is to provide a space to engage with the wheel groove 413. The height of the slider 414 is lower than the height of the wheel groove 413, and the width of the slider 414 is greater than the depth of the wheel groove 413. This allows the slider 414 to be pressed or lifted, thereby controlling whether the outer cam plate 412 is pressed downward by the slider 414, and thus controlling whether the connecting rod 42 connected to the outer cam plate 412 is lowered.

[0077] A pull rod 415 is located on the outside of the outer cam plate 412, with one end connected to the slider 414 and the other end slidably connected to the limiting mechanism 416. The limiting mechanism 416 is located above the pull rod 415, with one end sleeved with the pull rod 415 and the other end connected to the pull ring 417. Pulling the pull ring 417 controls the pull rod 415 through the limiting mechanism 416, thereby controlling the slider 414, which in turn controls the outer cam plate 412, which in turn controls the connecting rod 42, which in turn controls the limiting mechanism 8, thus achieving the purpose of controlling whether the seed falls.

[0078] It should be noted that the number of outer cam plates 412 is the same as the number of grooving mechanisms 6, and the five outer cam plates 412 are evenly distributed around the inner cam 411. The outer cam plates 412 are elastically connected to the outer surface of the body 5, thereby realizing the function of being pressed.

[0079] The limiting mechanism 416 includes a sleeve rod 4161, a limiting elastic element 4162, a first limiting block 4163, and a second limiting block 4164. The first limiting block 4163 is disposed at the top end of the sleeve rod 4161 and is fixedly connected to the sleeve rod 4161. The second limiting block 4164 is disposed at the top end of the pull rod 415, with one end connected to the top end of the pull rod 415 and the other end slidably connected to the sleeve rod 4161. The limiting elastic element 4162 is disposed around the sleeve rod 4161, with one end connected to the upper surface of the second limiting block 4164 and the other end connected to the first limiting block 4163. The lower surface is connected, and the limiting elastic element 4162 is pushed downward, causing the second limiting block 4164 to slide downward along the sleeve rod 4161, causing the pull rod 415 to also slide downward, causing the outer cam plate 412 to be squeezed downward, causing the grounding rod 81 to also move downward, causing the lever 831 to abut against the narrow opening 73, and finally causing the ground plane 833 to contact the ground. The operation of the limiting mechanism 8 can also be prohibited by manual control, so that the lever 831 does not move, the limiting elastic element 4162 is released, and the second limiting block 4164 returns to its original position under the action of the limiting elastic element 4162, causing the pull rod 415 to return to its original position, so that when the ground plane 833 contacts the ground, a lever action occurs, thereby restoring the normal working state.

[0080] like Figure 1 As shown, the bracket 2 includes a fixing ring 21 and a handle 22; the handle 22 is located on the outside of the pull ring 417 and is movably connected to the bracket 2. The detachable design facilitates organization. The fixing ring 21 is located on the outer surface of the bracket 2 along the pull rod 415 and is movably connected to the bracket 2. The pull rod 415 and the fixing ring 21 are sleeved together to fix the overall direction of the pull rod 415, which is convenient for personnel to operate.

[0081] Usage instructions and working principle:

[0082] I. Preparations before sowing

[0083] 1. Seed filling: The seeds are injected into the seed storage chamber 72 through the seed inlet 71 of the seed storage mechanism 7 to complete the seed storage work before sowing.

[0084] 2. Assembly and placement of the device: Ensure that all components such as the seeding wheel 1, the support 2, the pressing wheel 3, and the control device 4 are properly connected. Install the pressing wheel 3 at the end of the support 2 (if it was previously disassembled for easy carrying). Place the device at the starting position of the field to be sown, so that the seeding wheel 1 contacts the ground. At the same time, the operator holds the handle 22 of the support 2 and is ready to operate.

[0085] 3. Sowing operation

[0086] (1) Normal sowing: The operator pushes the device forward, and the sowing wheel 1 rolls accordingly. When the ground contact rod 81 of the limiting mechanism 8 contacts the ground, the ground contact rod 81 slides upward under the upward squeezing force of the ground, and the limiting elastic element 82 is compressed. This causes the lever mechanism 83 located inside the body 5 to move downward and disengage from the narrow opening 73. The seeds in the seed storage bin 72 fall into the outlet 9, and then fall out of the outlet 92 through the seed channel 91, completing the sowing. As the sowing wheel 1 continues to roll, continuous sowing is achieved. At the same time, the furrowing mechanism 6 (blade) on the outside of the sowing wheel 1 will open small furrows on the ground during the rolling process, making it easier for the seeds to fall into the furrows. Meanwhile, the soil pressing wheel 3, which is on the same horizontal line, will cover the sown area with soil.

[0087] (2) Manual control of sowing pause: When it is necessary to manually control the seeds from falling, the pull ring 417 of the control device 4 can be pushed downwards. The pull ring 417 controls the pull rod 415 through the limiting mechanism 416. The pull rod 415 drives the slider 414 to move in the wheel groove 413, thereby controlling the outer cam plate 412 to be pressed downwards, that is, pushing the limiting elastic element 4162 downwards, so that the second limiting block 4164 slides downwards along the sleeve rod 4161, driving the pull rod 415 to slide downwards as well, so that the outer cam plate 412 is pressed downwards. When 12 is squeezed downwards, the ground contact rod 81 also moves downwards, causing the lever 831 to abut against the narrow passage 73. When the ground plane 833 contacts the ground, it can also prevent the operation of the limiting mechanism 8, thus pausing sowing. After the limiting elastic element 4162 is released, the second limiting block 4164 returns to its original position under the action of the limiting elastic element 4162. The pull rod 415 and the ground contact rod 81 and other components also return to their original positions accordingly. When the ground plane 833 contacts the ground, it will restore the normal lever action and continue the sowing work.
