[0046] At present, for large-scale rapeseed planting, such as large rapeseed planting bases and rapeseed sea scenic spots, large-scale automated sowing machines are usually used for sowing, because the growth density and overall growth direction of rapeseed need to be controlled. They can realize the integrated sowing operation of rotary tillage, fertilization and sowing, but such equipment is expensive and has high requirements for the planting site, and is not suitable for small-scale planting. For individual farmers, small-scale business enterprises and rapeseed planting in mountainous areas, small rapeseed seeders or wheat seeders are used for sowing, and some even rely on manual sowing for sowing.

[0047] In small-scale planting, a mixed sowing method of fertilizer and seeds is often used. However, since it is difficult to achieve quantitative control of fertilizer and seeds, uneven sowing is prone to occur, which not only causes waste of seeds and fertilizers, but may also reduce the absorption and utilization rate of fertilizers.

[0050] In the rapeseed sowing device provided by the above-mentioned embodiment of the present invention, the seeds and fertilizers in the discharge trough are transported to the sowing mechanism by the rotation of the discharge wheel, and the seeds and fertilizers are mixed in the mixing bin and sown by the sowing mechanism. The volume of the discharge trough is controlled by the adjustment component, so that the sowing amount of seeds and fertilizers can be quantitatively controlled. During sowing, the sowing amount of seeds and fertilizers can be accurately controlled according to the set ratio, which can effectively reduce the waste of seeds and fertilizers and improve the absorption and utilization rate of fertilizers by seeds.

[0051] The present invention is described below by several specific embodiments. In order to keep the following description of the embodiments of the present invention clear and concise, the detailed description of known functions and known components may be omitted. When any component of the embodiments of the present invention appears in more than one accompanying drawings, the component may be represented by the same reference numeral in each of the accompanying drawings.

[0052] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a rapeseed sowing device, including: a frame 1, a seed bin 2, a fertilizer bin 3, a quantitative discharging mechanism 4 and a sowing mechanism 5. Among them, the seed bin 2 is connected to the frame 1, and a seed discharge port is arranged at the bottom; the fertilizer bin 3 is connected to the frame 1, and is located on one side of the seed bin 2, and a fertilizer discharge port is arranged at the bottom of the fertilizer bin 3; a quantitative discharge mechanism 4 is arranged in the seed discharge port and the fertilizer discharge port, and the quantitative discharge mechanism 4 includes a discharge wheel 41 and an adjustment component 42, the discharge wheel 41 is rotatably connected to the bottom of the seed bin 2, and at least one discharge groove 411 is opened on the circumferential side wall of the discharge wheel 41, and the length direction of the discharge groove 411 is parallel to the axis of the discharge wheel 41, and the adjustment component 42 can adjust the volume of the discharge groove 411; the sowing mechanism 5 is movably connected to the frame 1, and is located below the seed bin 2 and the fertilizer bin 3, the sowing mechanism 5 includes a mixing bin 51, the seed discharge port and the fertilizer discharge port are both connected to the mixing bin 51, and a discharge port is arranged at the bottom of the mixing bin 51.

[0053] Specifically, the frame 1 can be a frame structure welded with square steel, which is used to connect and fix various components of the rapeseed sowing device. The seed bin 2 and the fertilizer bin 3 can both be square shell structures with open tops, and the bottoms of the seed bin 2 and the fertilizer bin 3 gradually converge toward the middle in the width direction, or the bottom surfaces of the seed bin 2 and the fertilizer bin 3 converge toward the center and are inclined to facilitate feeding.

[0054] Further, refer to Figure 4 , Figure 5As shown, a quantitative discharging mechanism 4 is provided in the seed discharging port of the seed bin 2 and the fertilizer discharging port of the fertilizer bin 3. After the quantitative discharging mechanism 4 discharges a certain amount of seeds and fertilizers, they are mixed in the mixing bin 51 and sown by the sowing mechanism 5. For example, the quantitative discharging mechanism 4 provided in the seed bin 2 includes a discharging wheel 41 and an adjusting component 42. The discharging wheel 41 is provided in the seed discharging port and is rotatably connected to the seed bin 2. The cross section of the discharging wheel 41 can overlap with the seed discharging port, that is, the discharging wheel 41 can completely block the seed discharging port; a discharging groove 411 is provided on the side wall of the discharging wheel 41. The length direction of the discharging groove 411 is parallel to the axis of the discharging wheel 41. When the discharging wheel 41 rotates, the seeds contained in the discharging groove 411 can be discharged, and the volume of the discharging groove 411 is the discharging amount of the seeds; the volume of the discharging groove 411 is adjusted by the adjusting component 42, thereby controlling the discharging amount of the seeds. Therefore, by means of the quantitative discharging mechanism 4 provided in the seed discharging port and the fertilizer discharging port, quantitative control of seeds and fertilizers can be achieved, thereby reducing the waste of seeds and fertilizers and facilitating improving the absorption and utilization rate of fertilizers by seeds.

[0055] It should be noted that a plurality of discharge troughs 411 may be evenly spaced around the axis of the discharge wheel 41, and each discharge trough 411 is provided with an adjustment component 42, and the adjustment components 42 of the plurality of discharge troughs 411 can be adjusted simultaneously, so that the volumes of the plurality of discharge troughs 411 can always remain consistent, to ensure uniformity of sowing. Among them, the number of discharge troughs 411 and the rotation speed of the discharge wheel 41 are factors for controlling the sowing density, and thus, the number of discharge troughs 411 may be specifically set or the rotation speed of the discharge wheel 41 may be controlled according to the actual sowing density requirements, and the present invention does not specifically limit this.

[0056] In the above embodiment, if the discharging wheel 41 in the seed bin 2 and the discharging wheel 41 in the fertilizer bin 3 cannot rotate synchronously, it may cause the seeds and fertilizers to fail to enter the mixing bin 51 at the same time, resulting in insufficient mixing, which may easily cause uneven sowing during continuous sowing.

[0057] To this end, an embodiment of the present invention provides an improved approach.

[0058] Reference Figure 1 , Figure 3 As shown, the quantitative discharging mechanism 4 also includes a driving motor 48 and a driving belt 49. The driving motor 48 is fixed on the frame 1, and the driving belt 49 connects the discharging wheel 41 in the seed bin 2 and the discharging wheel 41 in the fertilizer bin 3 to the output shaft of the driving motor 48.

[0059] For example, the discharge wheel 41 in the seed bin 2 and the discharge wheel 41 in the fertilizer bin 3 are both connected to a rotating rod, a sprocket is fixedly sleeved on the rotating rod, a sprocket is also arranged on the output shaft of the driving motor 48, and the driving belt 49 is a chain. When the driving motor 48 is started, the discharge wheel 41 in the seed bin 2 and the discharge wheel 41 in the fertilizer bin 3 can be driven to rotate simultaneously through the driving belt 49, so that the seeds and fertilizers can enter the mixing bin 51 at the same time, which is beneficial to the uniformity of sowing. In addition, the rotation speed of the discharge wheel 41 can be controlled by controlling the rotation speed of the driving motor 48, and then the density of sowing can be controlled.

[0060] In an exemplary embodiment of the present invention, the adjustment component 42 includes a slider 44 and a driving member. Receiving holes 43 are provided at both ends of the discharge trough 411. The slider 44 is slidably arranged in the receiving hole 43. Sliders 44 are provided in the receiving holes 43 on both sides; the driving member is used to drive the slider 44 to slide in the receiving hole 43.

[0061] Specifically, the receiving hole 43 is opened on both sides along the length direction of the discharge trough 411, and only one side of the receiving hole 43 facing the discharge trough 411 is open, and the top of the receiving hole 43 is closed, and the seeds will not enter the receiving hole 43. Therefore, when the slider 44 slides in the receiving hole 43, the length of the discharge trough 411 can be changed, so that the volume of the discharge trough 411 can be adjusted. The driving member can be a telescopic rod provided in the receiving hole 43, and the slider 44 is fixedly connected to the telescopic end of the telescopic rod, so as to realize the sliding of the slider 44, and the driving member can also be other driving structures.

[0062] For example, refer to Figure 6 and Figure 7 As shown, the driving member includes a slip ring 45, a sliding sleeve 46 and a rotating shaft 47, and a sliding hole communicating with the inside of the discharge wheel 41 is opened at the bottom of the accommodating hole 43. Among them, the slip ring 45 is arranged inside the discharge wheel 41 and is provided with two slip rings 45, and the two slip rings 45 are respectively fixedly connected with the sliders 44 on both sides; the inner rings of the two slip rings 45 are respectively threadedly connected with a sliding sleeve 46, and the two sliding sleeves 46 are fixedly sleeved on the rotating shaft 47. The axes of the slip ring 45, the sliding sleeve 46 and the rotating shaft 47 are all coincident with the axis of the discharge wheel 41, and the threads of the two slip rings 45 are arranged in opposite directions. When the rotating shaft 47 drives the two sliding sleeves 46 to rotate, it can drive the two slip rings 45 to slide in the direction of approaching or moving away from each other, thereby driving the two sliders 44 to approach or move away from each other, and realizing the control of the volume of the discharge trough 411.

[0063] At the same time, the rotating shaft 47 is rotatably connected with the seed bin 2, and a tightening bolt is screwed on the rotating shaft 47, and a hand wheel can be set at the end of the rotating shaft 47. When it is necessary to adjust the volume of the discharge trough 411, loosen the tightening bolt so that the rotating shaft 47 can rotate relative to the discharge wheel 41, rotate the rotating shaft 47 by the hand wheel, and drive the slider 44 to slide, so that the volume of the discharge trough 411 can be adjusted to an appropriate position; when the tightening bolt is screwed, the relative position of the rotating shaft 47 and the discharge wheel 41 is fixed, and the rotating shaft 47 will no longer rotate relative to the discharge wheel 41. When the driving motor 48 drives the discharge wheel 41 to rotate, it can drive the rotating shaft 47 to rotate together, and the sliding sleeve 46 and the slip ring 45 will not slide relative to each other, so that the position of the slider 44 remains unchanged, and the volume of the discharge trough 411 will not change.

[0064] In an exemplary embodiment of the present invention, a plurality of sowing mechanisms 5 may be provided, and each sowing mechanism 5 corresponds to a group of quantitative discharging mechanisms 4 arranged in the seed bin 2 and a group of quantitative discharging mechanisms 4 arranged in the fertilizer bin 3 .

[0065] For example, three groups of sowing mechanisms 5 are arranged at intervals, so that three groups of quantitative discharging mechanisms 4 are arranged in the seed bin 2, and three groups of quantitative discharging mechanisms 4 are also arranged in the fertilizer bin 3, so that three-way seeds can be sown simultaneously, which is beneficial to improving the sowing efficiency.

[0066] In one embodiment of the present invention, referring to Figure 1 , Figure 3 As shown, the sowing mechanism 5 also includes a fixed rod 52, a mounting seat 53, a furrowing knife 54 and a discharge pipe 55. The fixed rod 52 is connected to the frame 1, and the length direction of the fixed rod 52 is parallel to the length direction of the discharge wheel 41; the mounting seat 53 is movably connected to the fixed rod 52; the furrowing knife 54 is fixed to the mounting seat 53; the discharge pipe 55 is connected to the discharge port at the bottom of the mixing bin 51 through a hose, and the discharge pipe 55 is connected to the furrowing knife 54.

[0067] Specifically, the fixing rod 52 is a square rod connected to the frame 1, the mounting seat 53 is movably connected to the fixing rod 52, the trenching knife 54 is fixed on the mounting seat 53, the discharge pipe 55 can be arranged inside the trenching knife 54, or can be fixed outside the trenching knife 54, and the port of the discharge pipe 55 is located on the side away from the blade of the trenching knife 54. When the sowing device is moving, the trenching knife 54 is used to open a sowing groove for seeds and fertilizers. After the seeds and fertilizers are mixed in the mixing bin 51, they are discharged into the groove opened by the trenching knife 54 through the hose and the discharge pipe 55, thereby achieving sowing.

[0068] In the above embodiment, when multiple groups of sowing mechanisms 5 are provided, the distances between the multiple groups of sowing mechanisms 5 are fixed, so that the sowing width cannot be adjusted, which may restrict sowing in complex terrain.

[0069] To this end, an embodiment of the present invention provides an improved approach.

[0070] The sowing mechanism 5 also includes a lateral adjustment component, which is used to adjust the connection position of the mounting seat 53 along the length of the fixed rod 52. Specifically, the mounting seat 53 is movably connected to the fixed rod 52, and the connection position of the mounting seat 53 is adjusted by the lateral adjustment component, so that multiple sowing mechanisms 5 can be fixed at different positions on the fixed rod 52, thereby realizing the adjustment of the sowing width.

[0071] For example, the lateral adjustment component includes a fixing bolt, and a plurality of fixing holes are provided on the fixing rod 52 at intervals along the length direction. The mounting seat 53 is fixedly connected to the fixing rod 52 via the fixing bolt, and the fixing bolt is fixedly screwed to different positions of the fixing rod 52, so that the connection position of the mounting seat 53 can be adjusted.

[0072] In the above embodiment, the height of the sowing mechanism 5 is fixed, so that the height of the furrowing knife 54 is fixed, and the depth of the furrows opened by the furrowing knife 54 is fixed, resulting in a fixed sowing depth.

[0073] To this end, an embodiment of the present invention provides an improved approach.

[0074] The sowing mechanism 5 also includes a vertical adjustment component, which is used to adjust the installation position of the fixing rod 52 on the frame 1 in the vertical direction. Specifically, by adjusting the installation position of the fixing rod 52 in the vertical direction, the installation height of the sowing mechanism 5 can be adjusted, and then the height of the furrowing knife 54 can be adjusted, so that the furrowing depth of the furrowing knife 54 can be adjusted, which is convenient for achieving the sowing needs on different terrains.

[0075] For example, the vertical adjustment assembly includes a hydraulic cylinder, which is fixed on the frame 1 and is provided with two hydraulic cylinders, respectively located on both sides of the frame 1. The two ends of the fixed rod 52 are respectively connected to the telescopic ends of the two hydraulic cylinders, so that the height of the fixed rod 52 can be adjusted.

[0076] In an exemplary embodiment of the present invention, a plurality of baffles 511 are spaced apart and staggered on two opposite side walls in the mixing bin 51 , and the plurality of baffles 511 are all tilted downward.

[0077] For example, the mixing bin 51 is a square shell structure, and a plurality of baffles 511 are spaced and staggeredly connected on two opposite side walls inside the mixing bin 51. The plurality of baffles 511 are all tilted downward, and the width of the baffles 511 is consistent with the width of the mixing bin 51. The length of the baffles 511 in the orthographic projection direction is greater than half the length of the mixing bin 51. After the seeds and fertilizers enter the mixing bin 51 at the same time, they are blocked by the plurality of baffles 511, so that the seeds and fertilizers are mixed more fully.

[0078] In an exemplary embodiment of the present invention, referring to Figure 1 and Figure 2 As shown, the rape seeding mechanism 5 may further include a loosening mechanism 6 and a soil covering mechanism 7. The loosening mechanism 6 is connected to the frame 1 and is located in front of the seeding mechanism 5 in the traveling direction, and is used to loosen the soil; the soil covering mechanism 7 is connected to the frame 1 and is located behind the seeding mechanism 5 in the traveling direction, and is used to cover the tilled soil on the seed material.

[0079] Specifically, the loosening mechanism 6 may include multiple rotary tillers, which can loosen the soil before the furrowing knife 54 digs the furrow, making it easier for the furrowing knife 54 to open a seed furrow and avoid exposing all the seeds outside the soil; the covering mechanism 7 may include a scraper, each group of sowing mechanisms 5 corresponds to a scraper, and the scraper can bury the furrows opened by the furrowing knife 54, making it easier to cover the seeds and fertilizers with soil and improve the survival rate of the seeds.

[0080] The implementation method of the present invention is as follows: before sowing, according to the required ratio of seeds and fertilizers, the volume of the discharge trough 411 in the seed bin 2 and the fertilizer bin 3 is adjusted by rotating the rotating shaft 47. After the volume of the discharge trough 411 is adjusted to the set size, the tightening bolt is screwed to fix the position of the rotating shaft 47 and the discharge wheel 41, and the speed of the driving motor 48 is set according to the required sowing density; thereafter, seeds and fertilizers are added to the seed bin 2 and the fertilizer bin 3 respectively, and the sowing device is pulled forward by the frame 1, and the driving motor 48 drives the discharge wheels 41 in the seed bin 2 and the fertilizer bin 3 to rotate simultaneously, thereby discharging a certain amount of seeds and fertilizers into the mixing bin 51; at the same time, the sowing device opens a groove with the ditching knife 54 during the advancement, and the seeds and fertilizers enter the groove through the discharge pipe 55, and are covered with soil during the advancement and under the action of the soil covering mechanism 7, thereby achieving sowing.

[0081] The above inventions are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
