Description
Technical Field
[0001] This invention relates to the field of farmland planting technology, specifically to a farmland furrow planting device. Background Technology
[0002] Ridge-furrow planting technology, by creating ridges and furrows in the field, effectively improves soil aeration and drainage, reduces water evaporation, and improves the plant growth environment. With the development of agricultural mechanization and the emergence of various automated equipment, farming efficiency has increased and labor costs have decreased. Ridge-furrow planting equipment combines automation technology, making the planting process more efficient. However, in traditional ridge-furrow planting equipment, the bottom opening size of the seed storage container is usually fixed. Furthermore, because different seeds have different sizes, shapes, and granule requirements, keeping the outlet size constant can lead to some seeds being discharged excessively or not at all, making it difficult to adjust the seed quantity according to crop needs. Summary of the Invention
[0003] In view of the shortcomings of the prior art, the purpose of this invention is to provide a farmland furrow planting device to solve the problem mentioned in the background art that it is difficult to adjust the seed dispensing amount according to the crop needs in traditional furrow planting devices.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a farmland furrow planting device, including a pusher frame, on which a storage container is installed for controlling the seed discharge rate by adjusting the size of the outlet, and a seed delivery component is installed at the bottom outlet of the storage container for intermittently delivering seeds to the furrow, and two dispersion cylinders for uniformly dispersing the seeds are detachably fitted at the outlet of the seed delivery component.
[0005] The storage container includes a flat storage hopper and a rectangular discharge frame integrally installed at the bottom of the flat storage hopper. An inclined guide plate is fixedly installed on one inner wall of the rectangular discharge frame. Several concave grooves are opened on the top surface of the guide plate. A movable plate is rotatably installed on the other inner wall of the rectangular discharge frame. An adjustment component is installed on the inner wall of the flat storage hopper to adjust the tilt angle of the movable plate to control the size of the opening between it and the guide plate.
[0006] Preferably, the combined length of the guide plate and the movable plate is greater than the internal length of the rectangular discharge frame, and the guide plate is located below the movable plate;
[0007] The tilt angle of the guide plate is between 20° and 45°.
[0008] Preferably, the adjusting assembly includes a limiting structure installed on the top surface of the movable plate, a fixing block installed on the inner wall of the flat storage hopper, an adjusting rod threaded into the top of the fixing block, a connecting shaft rotatably sleeved on the bottom of the adjusting rod, a hanging plate rotatably sleeved on the connecting shaft, an insertion structure extending into the limiting structure integrally installed on the outer surface of the hanging plate, and a cylindrical structure rotatably sleeved on the outer surface of the insertion structure.
[0009] Preferably, the outer surface of the limiting structure is provided with an inclined groove that slopes upward from the outside to the inside, and an embedded groove that communicates with the inclined groove is provided inside the limiting structure. The height of the embedded groove is consistent with the outer diameter of the cylindrical structure, and the top surface of the limiting structure slopes from the middle to both sides.
[0010] Preferably, the plug-in structure consists of a rhomboid block adapted to the oblique groove and a round shaft integrally connected to the rhomboid block, and the cylindrical structure is sleeved on the outer surface of the round shaft.
[0011] Preferably, the dispensing component includes a stepper motor mounted on a pusher frame, and a rotating shaft extending into the rectangular discharge frame is connected to the output end of the stepper motor. Five sets of equidistant, ring-shaped dividing blades are installed on the outer surface of the rotating shaft, and the length of the dividing blades is the same as the width of the rectangular discharge frame. The distance between one side of the dividing blade and the central axis of the rotating shaft is half the length of the rectangular discharge frame.
[0012] Preferably, the bottom of the rectangular discharge frame is integrally installed with a shrinkage frame that is round at the top and round at the bottom. Two branch pipes are installed at the bottom of the shrinkage frame, and the top of the branch pipes is semi-circular. The dividing line between the tops of the two branch pipes is arranged horizontally, and an inclined guide tube is connected to the bottom of the branch pipes.
[0013] Preferably, the dispersing cylinder includes a threaded cylinder detachably sleeved at the tail end of the inclined guide tube, a feeding cylinder integrally connected to the bottom of the threaded cylinder in a narrow-at-the-top and wide-at-the-bottom arrangement, and at least three spiral blades arranged in a clockwise staggered pattern installed on the inner wall of the feeding cylinder.
[0014] By employing the above technical solution, the present invention provides a farmland furrow planting device, which has at least the following beneficial effects:
[0015] 1. This invention uses an adjusting rod that rotates up or down to adjust the structure below, generating an upward pulling force or a downward pushing force on the limiting structure. This controls the tilt angle of the movable plate, thereby adjusting the opening and closing size of the gap between the movable plate and the guide plate. This achieves more precise control over the rate and quantity of seed falling, and is more adaptable to different seed sizes and shapes, exhibiting high compatibility.
[0016] 2. By setting the inlet of the straight groove into which the limiting structure allows the insertion structure and the cylindrical structure to slide, the present invention can effectively prevent seeds near the outside of the inclined groove from entering the space inside the limiting structure, thereby ensuring the smooth sliding of the cylindrical structure relative to the inside of the limiting structure.
[0017] 3. The present invention uses the triangular gap formed between two adjacent separating blades to load seeds that fall from the gap between the movable plate and the guide plate. Then, with the intermittent low-speed operation of the stepper motor, the seeds can be intermittently released according to the spacing of the planting pits on the field ridge.
[0018] 4. This invention effectively improves the uniform distribution of seeds in the feeding cylinder by adding staggered spiral blades inside the feeding cylinder. At the same time, the cone shape of the feeding cylinder itself, which is narrow at the top and wide at the bottom, effectively improves the dispersion of seeds when they are placed in the planting pit.

[0032] Example 1
[0033] Please refer to Figures 1-6 This embodiment proposes a furrow planting device for farmland, which can accurately control the seed drop rate and quantity. The furrow planting device has a pusher frame 1, which consists of a horizontal steel plate, a push handle, and wheels mounted on both sides of the bottom of the horizontal steel plate. The distance between the two wheels is adapted to the distance between two sets of furrows in the field, facilitating simultaneous planting on both sets of furrows. A storage container 2 is installed on the pusher frame 1 to control the seed discharge rate by adjusting the outlet size. A seed delivery component 3 is installed at the bottom outlet of the storage container 2 for intermittently delivering seeds to the furrows. Two dispersing cylinders 4 are detachably fitted at the outlet of the seed delivery component 3 to ensure even seed distribution. In practical applications, the seeds to be planted are stored inside the storage container 2. Then, force is applied to the pusher 1 to push it to the set position in the field. The opening size of the storage container 2 is then adjusted as needed so that the seeds fall down into the dispensing component 3 at the required rate. After that, the seeds slide down along the internal path of the dispensing component 3 into the two dispensing cylinders 4, and then fall down along the internal path of the dispensing cylinders 4 into the planting troughs that have been dug in advance on the field ridges, thereby achieving the purpose of dispensing the seeds.
[0034] To achieve the goal of adjusting the opening size of storage container 2 according to the amount of seed particles added, such as Figures 1-4As shown, the storage container 2 includes a flat storage hopper 201 and a rectangular discharge frame 202 integrally installed at the bottom of the flat storage hopper 201. An inclined guide plate 203 is fixedly installed on the inner wall of one side of the rectangular discharge frame 202. The top surface of the guide plate 203 is provided with several concave grooves 2031. A movable plate 204 is rotatably installed on the inner wall of the other side of the rectangular discharge frame 202. An adjustment component 205 is installed on the inner wall of the flat storage hopper 201 to adjust the tilt angle of the movable plate 204 to control the size of the opening between it and the guide plate 203. The adjustment of the opening size of storage container 2 is intended to adjust the bottom opening of the flat storage hopper 201. This is achieved by adjusting component 205 to control and maintain the tilt angle of movable plate 204. Furthermore, since the combined length of guide plate 203 and movable plate 204 is greater than the internal length of rectangular discharge frame 202, and guide plate 203 is located below movable plate 204, with a tilt angle between 20° and 45°, rotating movable plate 204 downwards by a set angle causes the bottom of movable plate 204 to fit against the tilted top surface of guide plate 203, thus sealing the flat storage hopper 201. Conversely, when movable plate 204 is rotated upwards by adjusting component 205, a gap is created between movable plate 204 and guide plate 203, allowing seeds to slide downwards. Adjusting the size of this gap affects the seed flowability, thereby achieving more precise control over the seed drop rate and quantity.
[0035] Specifically, the adjustment component 205 includes a limiting structure 2051 installed on the top surface of the movable plate 204, a fixing block installed on the inner wall of the flat storage hopper 201, an adjustment rod 2052 threadedly inserted into the top of the fixing block, a connecting shaft 2053 rotatably sleeved on the bottom of the adjustment rod 2052, a hanging plate 2054 rotatably sleeved on the connecting shaft 2053, an insertion structure 2055 extending into the interior of the limiting structure 2051 integrally installed on the outer surface of the hanging plate 2054, and a cylindrical structure 2056 rotatably sleeved on the outer surface of the insertion structure 2055. When adjusting the gap between the movable plate 204 and the guide plate 203, the adjusting rod 2052 is rotated up or down along the fixed block, causing it to rotate inside the connecting shaft 2053. This simultaneously moves the connecting shaft 2053, the hanging plate 2054, the plug-in structure 2055, and the cylindrical structure 2056 up or down, generating an upward pulling force or a downward pushing force on the limiting structure 2051. This force then transforms into a rotational force controlling the tilt angle of the movable plate 204, adjusting the gap between the movable plate 204 and the guide plate 203 to the desired size. Furthermore, as the movable plate 204 tilts under the rotational force, the plug-in structure 2055 and the cylindrical structure 2056 move relative to the limiting structure 2051, while the hanging plate 2054 rotates a certain angle relative to the connecting shaft 2053, preventing obstruction of the movable plate 204's tilt adjustment.
[0036] Therefore, by rotating the adjusting rod 2052 up or down, it causes the connecting shaft 2053, the hanging plate 2054, the plug-in structure 2055, and the cylindrical structure 2056 to adjust up and down accordingly. This generates an upward pulling force or a downward pushing force on the limiting structure 2051, thereby controlling the tilt angle of the movable plate 204. This adjusts the opening and closing size of the gap between the movable plate 204 and the guide plate 203, thus achieving a more precise control over the rate and quantity of seed falling.
[0037] Example 2
[0038] In Embodiment 1, to ensure that the plug-in structure 2055 and the cylindrical structure 2056 can follow the internal movement of the limiting structure 2051 when adjusting the tilt angle of the movable plate 204, a vertical sliding groove that allows movement is generally required on the limiting structure 2051. However, since the length of the vertical sliding groove is slightly long, seeds can easily enter the groove, thus affecting the movement of the plug-in structure 2055 and the cylindrical structure 2056. To effectively solve this problem, such as... Figures 3-4 As shown, the outer surface of the limiting structure 2051 is provided with an inclined groove 2057 that slopes upward from the outside to the inside. Inside the limiting structure 2051, there is an embedded groove 2058 that communicates with the inclined groove 2057. The height of the embedded groove 2058 is the same as the outer diameter of the cylindrical structure 2056. The top surface of the limiting structure 2051 slopes from the middle to both sides. The insertion structure 2055 is composed of a rhomboid block adapted to the inclined groove 2057 and a round shaft integrally connected to the rhomboid block. The cylindrical structure 2056 is sleeved on the outer surface of the round shaft. The combination of the embedded groove 2058 and the oblique groove 2057 forms a straight sliding groove that allows the insertion structure 2055 and the cylindrical structure 2056 to slide inside the limiting structure 2051. In addition, since the oblique groove 2057 is arranged upward from the outside to the inside and its inclination angle is greater than 45°, it can effectively prevent seeds near the outside of the oblique groove 2057 from entering the space inside the limiting structure 2051.
[0039] Example 3
[0040] Because seeds are typically sown in rows of holes rather than continuously, when planting on raised beds, it is generally necessary to sow them one by one. Figures 1-2 and Figure 5As shown, the dispensing component 3 includes a stepper motor 301 mounted on the pusher frame 1. A rotating shaft extending into the rectangular discharge frame 202 is connected to the output end of the stepper motor 301. Five sets of equidistant dividing blades 302 are mounted on the outer surface of the rotating shaft. The length of the dividing blades 302 is the same as the width of the rectangular discharge frame 202. The distance between one side of the dividing blade 302 and the central axis of the rotating shaft is half the internal length of the rectangular discharge frame 202. In practical applications, seeds sliding down through the gap between the movable plate 204 and the guide plate 203 will fall into the triangular gap formed by the two upward-facing separating blades 302. Based on this, with the intermittent operation of the stepper motor 301, it is caused to rotate 72° at low speed in a single rotation. This causes the two separating blades 302, which originally contained a certain amount of seeds, to gradually tilt downwards, and the seeds inside will slide down under their own gravity. At the same time, a certain amount of seeds are stored in another adjacent triangular gap. With the intermittent operation of the stepper motor 301, the seeds are intermittently released according to the spacing of the planting pits on the field ridge.
[0041] Specifically, a contraction frame 303 with a rounded top and bottom is integrally installed at the bottom of the rectangular discharge frame 202. Two branch pipes 304 are installed at the bottom of the contraction frame 303, and the top of the branch pipes 304 is semi-circular. The dividing line between the tops of the two branch pipes 304 is arranged horizontally. An inclined guide tube 305 is connected to the bottom of the branch pipes 304. Seeds falling down as the separating leaf 302 rotates will be distributed relatively evenly along the contraction frame 303 into the two branch pipes 304, and then slide down along the inclined guide tube 305 into the two dispersing cylinders 4, thereby realizing simultaneous planting on both ridges.
[0042] Example 4
[0043] like Figure 2 and Figure 6 As shown, the dispersing cylinder 4 includes a threaded cylinder 401 detachably sleeved at the tail end of the inclined guide tube 305. A feeding cylinder 402, narrower at the top and wider at the bottom, is integrally connected to the bottom of the threaded cylinder 401. At least three clockwise staggered spiral blades 403 are installed on the inner wall of the feeding cylinder 402. The staggered spiral blades 403 ensure uniform seed distribution within the feeding cylinder 402, preventing seed accumulation or uneven leakage due to gravity concentration, thus ensuring uniform sowing. Furthermore, the tapered shape of the feeding cylinder 402 helps guide seeds into the soil at a stable speed and direction, improving sowing accuracy. Compared to traditional straight pipe designs, the tapered feeding cylinder 402 can achieve uniform seed distribution within a limited area, improving seed dispersion when placing seeds in planting pits and preventing multiple seeds from clustering together.
[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. 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.
