DETAILED DESCRIPTION

[0017] To make the technical contents of the present application, the purposes achieved and the effects clear, the following will be described in combination with the embodiments and the accompanying drawings.

[0018] Please refer to Figures 1 to 4 The peanut seed sowing device with automatic seed supplementing comprises a seed sowing box 2, a seed sowing wheel 3, a seed blocking plate 11, a detection device 4, a seed supplementing box 5, a seed supplementing wheel 7 and a sliding plate 9. The seed sowing wheel 3 is arranged in the seed sowing box 2, and the seed sowing wheel 3 is provided with seed sowing holes 31 and seed sowing pushing grooves 32; the seed sowing box 2 is provided with the seed blocking plate 11 on the seed sowing side of the seed sowing wheel 3, and the seed blocking plate 11 is provided with a seed supplementing inlet 111 below; the detection device 4 is arranged above the seed blocking plate 11; and the detection end of the detection device 4 is arranged towards the seed sowing wheel 3. The seed supplementing box 5 is fixed on one side of the seed sowing box 2 close to the seed blocking plate 11, and the seed supplementing wheel 7 is arranged in the seed supplementing box 5; the seed supplementing wheel 7 is provided with seed supplementing holes 72 and seed supplementing pushing grooves 73; and the seed supplementing box 5 is provided with the sliding plate 9 on the seed supplementing side of the seed supplementing wheel 7, and the lower end of the sliding plate 9 is connected with the seed supplementing inlet 111.

[0019] As can be seen from the above description, the seed sowing holes 31 on the seed sowing wheel 3 provide an adaptive space for the initial seed sowing, the seed blocking plate 11 plays a role in restricting the seed sowing trajectory, the seed supplementing inlet 111 below provides a merging channel for the seed supplementing, the detection device 4 above can monitor the seed condition in the seed sowing holes 31 in real time and provide a basis for the seed supplementing decision; the seed supplementing box 5 is fixedly connected with the seed sowing box 2, so that the overall structure is compact; the seed supplementing holes 72 on the seed supplementing wheel 7 adapt to the seed supplementing demand; the sliding plate 9 accurately guides the seeds discharged by the seed supplementing wheel 7 into the seed supplementing inlet 111, realizes the smooth merging of the seed supplementing seeds and the seed sowing seeds, effectively guarantees the continuity of the seed sowing and the seed supplementing, and lays a structural foundation for the subsequent accurate and synchronous seed supplementing, which can solve the problem of insufficient seed sowing precision of the existing peanut seeding machine caused by the seed characteristics.

[0020] Please refer to Figure 2 and Figure 3In one or more embodiments, the reseeding box 5 is provided with a reseeding opening 22, and the lower end of the slide plate 9 is inserted into the reseeding opening 22 and connected with the reseeding inlet 111.

[0021] As can be seen from the above description, the reseeding opening 22 provides a passage for the slide plate 9, so that the seeds discharged by the reseeding wheel 7 can be smoothly guided into the reseeding inlet 111.

[0022] Please refer to Figure 8 In one or more embodiments, the seed discharge hole 31 is provided with two along the axial direction of the seed discharge wheel 3.

[0023] As can be seen from the above description, the structure of the seed discharge wheel 3 is adapted to the cultivation agronomic requirements of two peanuts per hole, and the two seed discharge holes 31 provided along the axial direction can synchronously carry the required seeds for a single hole, providing a basis for matching the number of initial seed discharge.

[0024] Please refer to Figure 3 and Figure 8 In one or more embodiments, it further includes a first seed ejecting rod 81 arranged below the seed discharge wheel 3, and the seed discharge wheel 3 is further provided with a seed discharge and ejecting groove 32; the seed discharge and ejecting groove 32 is arranged along the circumferential direction of the seed discharge wheel 3 and penetrates the seed discharge hole 31, and the depth of the seed discharge and ejecting groove 32 is greater than that of the seed discharge hole 31; the first seed ejecting rod 81 is inserted upward into the seed discharge and ejecting groove 32.

[0025] As can be seen from the above description, the first seed ejecting rod 81 can forcibly eject the seeds stuck in the seed discharge hole 31, avoid the interruption of seed discharge or trajectory deviation caused by the stuck seeds, and guide the seeds to move in a preset direction.

[0026] Please refer to Figure 3 and Figure 5 In one or more embodiments, it further includes a second seed ejecting rod 82 arranged below the reseeding wheel 7, and the reseeding wheel 7 is further provided with a reseeding and ejecting groove 73; the reseeding wheel 7 has two and is coaxially arranged side by side; the reseeding and ejecting groove 73 is arranged along the circumferential direction of the reseeding wheel 7 and penetrates the reseeding hole 72, and the depth of the reseeding and ejecting groove 73 is greater than that of the reseeding hole 72; the second seed ejecting rod 82 is inserted upward into the reseeding and ejecting groove 73.

[0027] As can be seen from the above description, the two coaxially arranged reseeding wheels 7 form independent and cooperative reseeding structures, which can flexibly realize unilateral reseeding or bilateral synchronous reseeding according to the seed discharge detection results, and accurately match the reseeding requirements of different seed shortage scenes; the reseeding and ejecting groove 73 arranged along the circumferential direction of the reseeding wheel 7 and having a greater depth than the reseeding hole 72 can provide sufficient operation space for the seed ejecting component, facilitate smooth ejecting of the seeds stuck in the reseeding hole 72, and avoid reseeding jam.

[0028] Please refer to Figure 4 and Figure 5In one or more embodiments, the two seed supplement wheels 7 are independently driven by two seed supplement wheel motors 13 arranged on both sides of the seed supplement box 5, and the rotation direction of the seed supplement wheel 7 is opposite to that of the seed sowing wheel 3.

[0029] As can be seen from the above description, the two seed supplement wheels 7 are designed to be independently driven by two motors on both sides, which can be individually controlled according to the seed sowing detection results. It can not only start the corresponding side seed supplement wheel 7 for precise seed supplement in the case of single-sided seed sowing hole 31 seed deficiency, but also drive the two seed supplement wheels 7 to synchronize seed supplement when both sides are seed deficient, greatly improving the flexibility and pertinence of seed supplement. At the same time, the opposite rotation direction design of the seed supplement wheel 7 and the seed sowing wheel 3 can make the discharge trajectory of the seed supplement seed and the seed sowing seed adapt to each other, which is more conducive to the seed supplement seed to smoothly flow into the seed sowing channel through the sliding plate 9.

[0030] Please refer to Figure 5 In one or more embodiments, the outer side of the seed supplement wheel 7 is provided with a position hole 71, and the two sides of the seed supplement box 5 are provided with a position sensor 12, which can detect the position of the position hole 71.

[0031] Preferably, when the position hole 71 on the seed supplement wheel 7 is detected by the position sensor 12, the position sensor 12 outputs a signal, which means that the seed supplement wheel 7 has turned to the predetermined position, and the control stops rotating at this time. The seed supplement wheel 7 stops at the initial position.

[0032] As can be seen from the above description, the position hole 71 on the outer side of the seed supplement wheel 7 and the position sensor 12 on both sides of the seed supplement box 5 form a precise positioning detection structure. The position sensor 12 provides a reliable basis for the driving control of the seed supplement wheel motor 13 by detecting the position of the position hole 71 in real time. It can ensure that the seed supplement wheel 7 can quickly reset to the pre-set accurate initial position and perform the seed supplement action when receiving the seed supplement instruction, avoiding problems such as inaccurate seed supplement timing and seed discharge trajectory deviation caused by position deviation of the seed supplement wheel 7, and effectively ensuring the accuracy of seed supplement.

[0033] Please refer to Figures 1 to 4 In one or more embodiments, the seed sowing box 2 is provided with a light inlet 21 close to the detection device 4.

[0034] As can be seen from the above description, the light inlet 21 can provide sufficient and stable light conditions for the detection device 4, effectively avoiding problems such as seed quantity recognition ambiguity and misjudgment caused by insufficient light.

[0035] Please refer to Figures 1 to 4 In one or more embodiments, the gap between the seed blocking plate 11 and the seed sowing wheel 3 is set to be large, small and then large along the vertical direction.

[0036] As can be known from the above description, in the seed sowing process, the seed first enters the seed blocking area through the large gap, then realizes posture regulation and motion synchronization through the intermediate reduced gap, and finally is smoothly discharged from the large gap, which not only effectively solves the problem of asynchronous sowing caused by the size and shape difference of peanut seeds, but also reduces the collision and extrusion between the seed and the seed blocking plate 11 and the seed sowing wheel 3, and reduces the risk of seed damage.

[0037] Please refer to Figures 1 to 4 and Figure 7 In one or more embodiments, the sliding plate 9 is inclined, and the width of the sliding plate 9 gradually decreases from the upper end to the lower end.

[0038] As can be known from the above description, the inclination of a certain angle can guide the smooth sliding of the reseeding seed by gravity, avoiding the retention of the seed; the gradually changing width structure can gradually converge the seed during the sliding process, preventing the seed from moving to both sides, and ensuring that the reseeding seed can accurately align the reseeding inlet 111 below the seed blocking plate 11.

[0039] Please refer to Figure 10 In one or more embodiments, a reseeding method of a peanut seed sowing device, when the number of seeds in two seed sowing holes 31 is greater than or equal to 2, the reseeding wheel motor 13 does not rotate and does not reseed; when the number of seeds in two seed sowing holes 31 is 1, if the number of seeds in the left seed sowing hole 31 of the seed sowing wheel 3 is 0, the left reseeding wheel motor 13 is started to drive the left reseeding wheel 7 to rotate and reseed, if the number of seeds in the right seed sowing hole 31 of the seed sowing wheel 3 is 0, the right reseeding wheel motor 13 is started to drive the right reseeding wheel 7 to rotate and reseed; when the number of seeds in two seed sowing holes 31 is 0, the left and right reseeding wheel motors 13 respectively drive the left and right reseeding wheels 7 to rotate and reseed.

[0040] As can be known from the above description, the method does not require manual intervention, and can automatically adjust the reseeding strategy according to different seed shortage scenarios, which not only guarantees the agronomic requirement of two seeds per hole, but also avoids the problem of excessive or insufficient reseeding.

[0041] Please refer to Figures 1 to 9 Embodiment one of the present application is: An automatic reseeding peanut seed sowing device, comprising a seed sowing box 2, a seed sowing wheel 3, a seed sowing scraping wheel 1, a seed pushing rod, a seed blocking plate 11, a detection device 4, a reseeding box 5, a reseeding wheel 7, a reseeding scraping wheel 6, a sliding plate 9, a position sensor 12, a reseeding wheel motor 13, a reseeding scraping wheel motor 14, and a seed outlet 10. The seed wheel 3 is arranged in the seed box 2, and a plurality of seed groove rows 31 and two seed groove rows 32 are arranged on the surface of the seed wheel 3. Each seed groove row 31 comprises two seed grooves 31, the seed groove 32 is connected to the seed groove 31, and the depth of the seed groove 32 is greater than that of the seed groove 31. The seed scraping wheel 1 rotates in the same direction as the seed wheel 3 and is arranged immediately above the seed wheel 3. The seed box 2 is provided with a seed blocking plate 11 on the seed side of the seed wheel 3 with a gap of “big→small→big”. The seed blocking plate 11 is provided with a seed supplementing inlet 111 below. The detection device 4 comprises a camera arranged above the seed blocking plate 11, and a light inlet 21 is arranged on the seed box 2 and close to the camera. The seed supplementing wheel 7 is arranged in the seed supplementing box 5, and the seed supplementing scraping wheel 6 is arranged immediately above the seed supplementing wheel 7 and rotates in the same direction as the seed supplementing wheel 7. The seed supplementing wheel 7 comprises a left wheel and a right wheel, and a plurality of seed groove rows 72 and a seed groove row 73 are arranged on the surface of the seed supplementing wheel 7. Each seed groove row 72 comprises one seed groove 72, the seed groove 73 is connected to the seed groove 72, and the depth of the seed groove 73 is greater than that of the seed groove 72. The left and right seed supplementing wheels 7 are independently driven and controlled by the seed supplementing wheel motor 13, and the rotating direction is opposite to that of the seed wheel 3. The seed supplementing scraping wheel 6 is driven and controlled by the seed supplementing scraping wheel motor 14. The left and right seed supplementing wheels 7 are provided with position holes 71 on the outer side, and the position sensor 12 installed on the two sides of the seed supplementing box 5 detects the initial position of the seed supplementing wheel 7. The seed supplementing wheel 7 is provided with a sliding plate 9 below the seed side, and the upper end of the sliding plate 9 is located in the seed supplementing box 5, and the lower end is inserted into the seed supplementing inlet 22 and communicates with the seed supplementing inlet 111. The seed wheel 3 and the seed supplementing wheel 7 are provided with seed supplementing rods below.

[0042] During operation, the seed supplementing scraping wheel motor 14 drives the seed supplementing scraping wheel 6 to rotate, and the seed supplementing wheel motor 13 drives the seed supplementing wheel 7 to rotate to the initial position according to the position of the position hole 71 of the seed supplementing wheel 7 detected by the position sensor 12. When the seed wheel 3 rotates (the rotating direction is opposite to that of the seed wheel 3), the seed supplementing wheel 7 rotates in the opposite direction. Figure 4As shown in the figure, the peanut seeds fall into the filling area 16 through the seed inlet 15 above the filling area 16, and then fall into the seed arranging holes 31 by gravity, and then the camera immediately identifies the number of single seeds and the cumulative number of seeds in the two seed arranging holes 31, and detects the rotating speed of the seed arranging wheel 3, and the system controls the seed supplementing wheel motor 13 to drive the seed supplementing wheel 7 (left or right or simultaneously) to rotate by a circumferential angle of a row of seed supplementing holes 72 according to a suitable rotating speed and time when the number of seeds in the holes is insufficient according to the identification and detection of the camera, and the seeds discharged from the seed supplementing holes 72 of the seed supplementing wheel 7 slide down into the seed supplementing inlet 111 through the slide plate 9, and are synchronously discharged with the seeds discharged from the seed arranging holes 31 after the seed blocking effect of the seed blocking plate 11, and then fall into the seed guiding pipe of the seeding machine through the seed outlet 10 arranged below the seed supplementing box 5; if the seeds are stuck in the seed arranging holes 31 or the seed supplementing holes 72 and cannot be smoothly discharged by gravity, the seeds are forced to be poked out of the seed arranging holes 31 or the seed supplementing holes 72 by the poking effect of the poking rod due to the close proximity of the poking rod.

[0043] Please refer to Figure 7 Embodiment two of the present application is: The difference between embodiment two and embodiment one is that the width of the slide plate 9 arranged obliquely gradually decreases from the upper end to the lower end, and side plates 91 are arranged on both sides of the slide plate 9, which can reduce the seed slippage phenomenon in the seed sliding process, thereby facilitating the gradual concentration of the seed sliding process and the synchronization with the seeds discharged from the seed arranging wheel 3. Please refer to Figure 4 The horizontal angle α of the slide plate 9 is 45°-60°, which is good for the seed sliding effect and is conducive to the synchronization with the seeds discharged from the seed arranging wheel 3.

[0044] In the present embodiment, the end of the seed poking rod away from the seed arranging and poking groove 32 or the seed supplementing and poking groove 73 is connected with a seat plate 811, and the seat plate 811 is connected with the seed arranging box 2 or the seed supplementing box 5. The seed supplementing wheel motor 13 is a stepping motor, which is conducive to the accurate control of the seed supplementing wheel 7, thereby improving the seed supplementing effect. The position sensor 12 is a proximity switch.

[0045] Please refer to Figure 10 Embodiment three of the present application is: The seed supplementing wheel motor 13 drives the seed supplementing wheel 7 to rotate for seed supplementing, and the following method is adopted: when the number of seeds in the two seed arranging holes 31 is greater than or equal to 2, the seed supplementing wheel motor 13 does not rotate, and no seed supplementing is performed; When the number of seeds in the two seed arranging holes 31 is 1, if the number of seeds in the seed arranging hole 31 on the left side of the seed arranging wheel 3 is 0, the left seed supplementing wheel motor 13 is started to drive the left seed supplementing wheel 7 to rotate for seed supplementing, and if the number of seeds in the seed arranging hole 31 on the right side of the seed arranging wheel 3 is 0, the right seed supplementing wheel motor 13 is started to drive the right seed supplementing wheel 7 to rotate for seed supplementing; When the seed quantity of the two seed arranging holes 31 is 0, the two side seed supplementing wheel motors 13 drive the left and right seed supplementing wheels 7 to rotate for supplementing.

[0046] In summary, the automatic peanut seed supplementing device and method provided by the present application has the following advantages. Two seed arranging holes 31 are arranged axially on the seed arranging wheel 3, and a seed arranging and supplementing groove 32 is arranged along the circumference of the seed arranging hole 31 and has a greater depth. The device is suitable for the agricultural requirement of two seeds per hole. The light inlet 21 arranged close to the detection device 4 on the seed arranging box 2 ensures the accuracy of seed quantity identification. In combination with the two coaxial and side-by-side seed supplementing wheels 7 driven by independent motors and rotating in the opposite direction of the seed arranging wheel 3, and the targeted seed supplementing logic, the device can accurately perform single or synchronous seed supplementing according to the seed quantity in the seed arranging hole 31, and greatly improves the qualified rate of double seeds. The position hole 71 on the outside of the seed supplementing wheel 7 cooperates with the position sensor 12 on the two sides of the seed supplementing box 5 to ensure that the initial position of the seed supplementing wheel 7 is accurately controllable. The sliding plate 9 arranged obliquely and gradually narrowing from top to bottom can guide the supplementing seeds to smoothly and centrally slide into the supplementing inlet 111, and the seeds discharged by the seed arranging wheel 3 are synchronously converged, further ensuring the consistency of seed arranging. The seed arranging rod below the seed arranging wheel 3 and the seed supplementing wheel 7 is inserted upward into the corresponding seed arranging groove, which can smoothly arrange the seeds stuck in the hole and guide them to move to the seed arranging side, thereby reducing the seed breakage rate. At the same time, the overall structure is relatively compact, and it is convenient to connect with other devices or components of the seeding machine.

[0047] The above description is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent transformation or direct or indirect application in related technical fields based on the content of the specification and drawings is also included in the patent protection scope of the present application.
