Description

Technical Field

[0001] This application relates to the field of rice broadcasting technology, and more specifically, to a seed storage box structure for a rice broadcasting machine. Background Technology

[0002] In the process of mechanization of rice planting, the seed storage box is a core component of the rice broadcasting machine, and its performance directly affects the efficiency and quality of the sowing operation.

[0003] Traditional seed storage boxes typically employ an open, bucket-shaped structure. The core logic of this design is to utilize the seeds' own gravity for flow and transport. Specifically, seeds are directly piled inside the storage box and naturally settle under gravity, flowing through channels at the bottom of the box to the seed metering device, thus completing the sowing process.

[0004] However, changes in the height of seed accumulation in traditional seed storage boxes affect the uniformity of discharging. When the seed storage box is full of seeds, a higher accumulation will cause the seeds at the bottom to bear greater pressure, resulting in the seeds squeezing and compacting against each other, causing blockage of the discharge port. As the sowing operation continues, the remaining seed in the seed storage box decreases, and the gravitational potential energy is insufficient to maintain a stable flow speed, resulting in intermittent discharge and affecting the sowing of seeds.

[0005] Therefore, there is an urgent need for a seed storage box structure that can control the seed dispensing speed. Summary of the Invention

The system includes a seed storage box, which has an internal, funnel-shaped storage space. Two partitions are symmetrically arranged inside the seed storage box, dividing the storage space into two side storage spaces and a central seed dispensing space, thus separating seed storage and dispensing. Multiple connecting holes are evenly distributed on each partition, connecting the two storage spaces to the seed dispensing space, and the connecting holes on the two partitions are at the same horizontal level. Multiple replenishing mechanisms are correspondingly arranged between the connecting holes at the same height on the two partitions, and their positions can be adjusted to block the connecting holes. A control mechanism is located on the seed storage box, used to control the position of each replenishing mechanism and thus control the opening of the connecting holes. A drive mechanism is located at the bottom of the seed storage box and magnetically connected to the control mechanism, providing power to the control mechanism. Two cleaning mechanisms are symmetrically arranged on both sides of the top of the seed storage box and fixedly connected to the two partitions, used to control the raising and lowering of the two partitions to clean residual seeds in the seed storage box.

[0009] In some embodiments, the system further includes: a seed metering box disposed at the bottom of the seed storage box and communicating with the seed metering space; a plurality of seed metering openings evenly distributed on the seed metering box; and a filling hopper disposed on top of the two partitions, the filling hopper being funnel-shaped.

[0010] In some embodiments, each of the supplementary mechanisms includes: a support member fixedly disposed between the two partitions, the support member including a support rod; a lever sleeved on the outside of the support rod of the support member; a blocking frame fixedly connected to the lever, the blocking frame having a seeding groove inside, and both sides of the blocking frame contacting the communicating holes on the two partitions; a first spring sleeved on the outside of the support rod and located at the top of the lever; and an isolation ring sleeved on the outside of the first spring.

[0011] In some embodiments, the isolation ring includes: a large isolation ring fixedly connected to the support member; and a small isolation ring fixedly connected to the toggle block and located inside the large isolation ring.

[0012] In some embodiments, the control mechanism includes: a mounting box disposed on one side of the seed storage box and located within the seed dispensing space; a lead screw disposed within the mounting box; a lifting block passing through the lead screw; a mounting base fixedly connected to the lifting block; a pressing member disposed at the end of the mounting base away from the lifting block; and a second spring disposed between the mounting base and the pressing member, wherein the second spring has a higher strength than the first spring.

[0013] In some embodiments, both the extrusion member and the paddle block have a smooth circular structure.

[0014] In some embodiments, the drive mechanism includes: a motor disposed on one side of the bottom of the seed storage box; a magnetic coupling connected to the motor; a rotating shaft connected to the magnetic coupling; and a bevel gear connected to the rotating shaft.

[0015] In some embodiments, the magnetic coupling includes: a first coupling connected to the motor output shaft; a second coupling connected to the rotating shaft; and two high-strength magnets respectively disposed on the contact surfaces of the first coupling and the second coupling.

[0016] In some embodiments, the bevel gear includes: a driving bevel gear disposed on the rotating shaft; and a driven bevel gear disposed at the end of the lead screw, wherein the driving bevel gear and the driven bevel gear mesh with each other.

[0017] In some embodiments, each of the bottom cleaning mechanisms includes: a limiting block, fixedly disposed in the top groove of the seed storage box; a screw, disposed on the limiting block and rotatable relative to the limiting block; a handwheel, disposed at the end of the screw away from the limiting block; and a connector, connected to the screw and fixedly connected to the two partitions.

[0018] Compared with the prior art, the technical solution provided in this application has at least the following technical effects:

[0019] This application provides a seed storage box structure for a rice broadcaster. The space within the seed storage box is divided to ensure a stable flow rate of seeds into the seed discharging space, thereby improving sowing accuracy and stability. Rice seeds enter the seed storage box and are dispersed in the seed storage spaces on both sides. A drive mechanism activates, transmitting power to a control mechanism. The control mechanism operates, adjusting the position of the replenishment mechanism from top to bottom according to preset requirements, changing the degree of obstruction of the connecting holes, thus controlling the opening of the through holes and consequently controlling the seed discharging speed. Under gravity, the seeds in the seed storage space flow through the connecting holes into the central seed discharging space. Because the connecting holes on both sides are at the same height and their openings are precisely controlled, the seed flow rate into the seed discharging space is stable and uniform. When the remaining seed in the seed storage space is low, two bottom-cleaning mechanisms raise the partition. Since the bottom of the seed storage box is funnel-shaped, the remaining seeds are naturally discharged. By using partitions to separate seed storage and seed dispensing areas, pressure fluctuations caused by direct seed accumulation are avoided. The design of the connecting holes at the same height and the precise control of the replenishment mechanism ensure a stable flow rate of seeds into the seed dispensing space, solving the problem of uneven seed dispensing caused by changes in seed height in traditional structures.

[0043] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0044] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0045] The following reference Figures 1 to 15 This application describes the seed storage box structure of a rice broadcaster provided according to some embodiments.

[0046] like Figure 1 , Figure 2As shown, the seed storage box structure of the rice broadcasting machine provided according to some embodiments of this application includes a seed storage box 110, partitions 130, connecting holes 132, a replenishment mechanism 200, a control mechanism 300, a drive mechanism 400, and a bottom cleaning mechanism 500. The seed storage box 110 has an internal accommodating space and is funnel-shaped. Two partitions 130 are symmetrically arranged within the seed storage box 110, dividing the accommodating space of the seed storage box 110 into two seed storage spaces on both sides and a seed dispensing space in the middle, thus separating seed storage and seed dispensing. Multiple connecting holes 132 are evenly distributed on each partition 130, connecting the two seed storage spaces and the seed dispensing space, and the connecting holes 132 on the two partitions 130 are at the same horizontal height. Multiple replenishment mechanisms 200 are correspondingly arranged at the connecting holes 132 at the same height on the two partitions 130. Between them, the position of the connecting hole 132 can be adjusted to block it; the control mechanism 300 is set on the seed storage box 110 and is used to control the position of the replenishing mechanism 200 one by one, and control the opening of the connecting hole 132; the drive mechanism 400 is set at the bottom of the seed storage box 110 and is magnetically connected to the control mechanism 300, and the drive mechanism 400 provides power to the control mechanism 300; two bottom cleaning mechanisms 500 are symmetrically set on both sides of the top of the seed storage box 110 and are fixedly connected to the two partitions 130, and are used to control the lifting and lowering of the two partitions 130 to clean the residual seeds in the seed storage box 110.

[0047] In this embodiment, rice seeds enter the seed storage box 110 and are dispersed in the seed storage spaces on both sides. The drive mechanism 400 is activated, transmitting power to the control mechanism 300, which then operates. According to preset requirements, the position of the replenishment mechanism 200 is adjusted from top to bottom to change its degree of obstruction of the connecting holes, thereby controlling the opening of the through holes and thus controlling the discharge speed of the rice seeds. Under the action of gravity, the seeds in the seed storage space enter the middle seed discharge space through the connecting holes 132. Since the connecting holes 132 on both sides are at the same height and the opening is precisely controlled, the flow rate of seeds entering the seed discharge space is stable and uniform. When the remaining seeds in the seed storage space are low, the two bottom cleaning mechanisms 500 drive the partition 130 to rise. Since the bottom of the seed storage box 110 is funnel-shaped, the remaining seeds are naturally discharged.

[0048] In this design, the partition 130 is used to separate the seed storage and seed dispensing areas, avoiding pressure fluctuations caused by direct seed accumulation. The connection hole 132 is designed at the same height as the replenishment mechanism 200, which ensures that the speed at which seeds flow into the seed dispensing space is stable, thus solving the problem of uneven seed dispensing caused by changes in seed height in traditional structures.

[0049] In some possible embodiments, such as Figures 3 to 6As shown, it also includes: a seed metering box 120, which is located at the bottom of the seed storage box 110 and is connected to the seed metering space; multiple seed metering ports 121, which are evenly distributed on the seed metering box 120; and a seed filling hopper 131, which is located on the top of the two partitions 130 and is funnel-shaped.

[0050] In this embodiment, the seed metering box 120 is used to connect the seed storage box 110 to the external sowing environment, receive the seeds falling from the seed metering space, and guide the seeds to be evenly distributed to each seed metering port 121. Multiple seed metering ports 121 are evenly distributed at the bottom of the seed metering box 120, and their number and spacing match the row spacing of sowing in the field to improve the sowing uniformity. The seed filling hopper 131 allows seeds to be directly added to the seed metering space.

[0051] It should be noted that the seed storage box 110, the seed metering box 120, the seed metering port 121, the partition 130, the seed filling hopper 131, and the connecting hole 132 together constitute the storage mechanism 100.

[0052] In some possible embodiments, such as Figure 7 , Figure 8 As shown, each supplementary mechanism 200 includes: a support member 210, fixedly disposed between two partitions 130, the support member 210 including a support rod; a lever 220, sleeved on the outside of the support rod of the support member 210; a blocking frame 230, fixedly connected to the lever 220, the blocking frame 230 having a seeding groove inside, and both sides of the blocking frame 230 contacting the connecting holes 132 on the two partitions 130; a first spring 240, sleeved on the outside of the support rod and located at the top of the lever 220; and an isolation ring 250, sleeved on the outside of the first spring 240; the isolation ring 250 includes: a large isolation ring, fixedly connected to the support member 210; and a small isolation ring, fixedly connected to the lever 220 and located inside the large isolation ring.

[0053] In this embodiment, initially, the first spring 240 is in its natural state, pushing the lever 220 upward. At this time, the blocking frame 230 completely blocks the connecting hole 132, preventing seeds from entering the seed discharging space from the seed storage space. The large isolation ring and the small isolation ring are nested together, and the control mechanism 300 moves to contact the lever 220, applying downward pressure. At this time, the lever 220 moves downward along the support rod, causing the blocking frame 230 to move downward synchronously. Thus, the degree of obstruction of the connecting hole 132 gradually decreases. Under the action of gravity, the seeds in the seed storage space enter the seed discharging groove of the blocking frame 230 through the connecting hole 132, then flow into the middle seed discharging space through the seed discharging groove, and finally are discharged through the discharge outlet of the seed discharging box 120. During this process... As the small isolation ring moves downward with the push block 220, it remains nested with the large isolation ring to prevent seeds from entering the gaps in the support rod and avoid jamming. Based on the remaining amount of seeds in the seed storage space, the control mechanism 300 adjusts the pressure on the push block 220. When the seeds in the seed storage space at this height are all discharged, the control mechanism 300 continues to move downward. The push block 220 is restricted by the support member 210, so the control mechanism 300 disengages from the current push block 220. The first spring 240 releases its elastic force to push the push block 220 upward, causing the blocking frame 230 to return to the state of blocking the connecting hole 132. Then the control mechanism 300 contacts the push block 220 at the next height and repeats the above process until the seeds corresponding to the lowest height blocking frame 230 are completely discharged.

[0054] In some possible embodiments, such as Figures 9 to 12 As shown, the control mechanism 300 includes: a mounting box 310, which is disposed on one side of the seed storage box 110 and located within the seed dispensing space; a lead screw 320, which is disposed within the mounting box 310; a lifting block 330, which passes through the lead screw 320; a mounting base 340, which is fixedly connected to the lifting block 330; a pressing member 350, which is disposed at the end of the mounting base 340 away from the lifting block 330; and a second spring 360, which is disposed between the mounting base 340 and the pressing member 350, wherein the strength of the second spring 360 is higher than that of the first spring 240; both the pressing member 350 and the lever 220 have a smooth circular structure.

[0055] In this embodiment, the drive mechanism 400 drives the lead screw 320 to rotate. Under the action of the threaded transmission, the lifting block 330 moves vertically along the lead screw 320, thereby driving the mounting base 340 and the extruder 350 to move synchronously. The lead screw 320 drives the extruder 350 to move downward, and its smooth circular end face contacts the corresponding height of the lever 220, applying downward pressure to the lever 220. Since the strength of the second spring 360 is higher than that of the first spring 240, the lever 220 overcomes the elastic force of the first spring 240 under the pressure and moves downward along the support rod of the support member 210, synchronously driving the belt. The moving blocking frame 230 moves down. When the toggle block 220 moves down to contact the support member 210, the support member 210 limits the toggle block 220, and the toggle block 220 can no longer move down. At this time, the screw 320 drives the lifting block 330 to move down, and the mounting base 340 moves down accordingly, squeezing the second spring 360 to compress it and gradually disengage from the toggle block 220. As the lifting block 330 continues to move down, the squeezing member 350, which has completely disengaged from the current toggle block 220, continues to move down and contacts the toggle block 220 at the lower height. The above process is repeated to realize the sequential control of the multiple different height supplementary mechanisms 200.

[0056] In some possible embodiments, such as Figures 12 to 14 As shown, the drive mechanism 400 includes: a motor 410, disposed on one side of the bottom of the seed storage box 110; a magnetic coupling 420, connected to the motor 410; a rotating shaft 430, connected to the magnetic coupling 420; and a bevel gear 440, connected to the rotating shaft 430. The magnetic coupling 420 includes: a first coupling, connected to the output shaft of the motor 410; a second coupling, connected to the rotating shaft 430; and two high-strength magnets, respectively disposed on the contact surfaces of the first coupling and the second coupling. The bevel gear 440 includes: a driving bevel gear, disposed on the rotating shaft 430; and a driven bevel gear, disposed at the end of the lead screw 320, wherein the driving bevel gear and the driven bevel gear mesh with each other.

[0057] In this embodiment, the motor 410 drives the output shaft to rotate, and the first coupling rotates synchronously. Since the high-strength magnets on the opposite surfaces of the first coupling and the second coupling attract each other, the rotation of the first coupling drives the second coupling to rotate synchronously through magnetic force. Consequently, the rotating shaft 430 connected to the second coupling rotates horizontally along with it, and drives the driving bevel gear to rotate. The driving bevel gear transmits the horizontal rotational motion to the driven bevel gear through meshing with the tooth surface of the driven bevel gear, causing the driven bevel gear to generate vertical rotational motion, thereby driving the lead screw 320 connected to it to rotate.

[0058] In some possible embodiments, such as Figure 15As shown, each bottom cleaning mechanism 500 includes: a limiting block 510, which is fixedly installed in the top groove of the seed storage box 110; a screw 520, which is installed on the limiting block 510 and can rotate relative to the limiting block 510; a handwheel 530, which is installed at the end of the screw 520 away from the limiting block 510; and a connecting piece 540, which is connected to the screw 520 and fixedly connected to the two partitions 130.

[0059] In this embodiment, when the seed height is lower than the minimum height of the connecting hole 132, the operator rotates the handwheel 530. The handwheel 530 drives the screw 520 to rotate on the limit block 510. Since the connecting piece 540 is threadedly connected to the screw 520, the connecting piece 540 will rise and fall along the screw 520. When the connecting piece 540 rises, it drives the two partitions 130 and the mounting box 310 fixedly connected to it to rise together. As the partitions 130 rise, the screw 320 and the second coupling inside the mounting box 310 also rise accordingly. At this time, the first coupling and the second coupling disengage. After the two partitions 130 rise, the seed storage space originally separated by the partitions 130 and the connecting area at the bottom of the seed storage box 110 are opened. The residual seeds at the bottom of the funnel-shaped seed storage box 110 can be discharged naturally under the action of gravity, realizing the cleaning of the bottom of the seed storage box 110. After the residual seeds are discharged, the screw 520 is reversed by rotating the handwheel 530 in the opposite direction. The connecting piece 540 moves downward along the screw 520, driving the partitions 130, the mounting box 310 and the second coupling to descend. Then the first coupling and the second coupling are automatically attracted under the action of magnetic force, restoring power transmission.

[0060] During operation, rice seeds are placed into the seed storage box 110 through the top. Two partitions 130 divide the seed storage box 110 into a seed storage space and a seed dispensing space. The seeds are evenly distributed in the seed storage spaces on both sides. Initially, the blocking frame 230 is located at the top of the seed dispensing space. The motor 410 starts, driving the magnetic coupling 420 and the rotating shaft 430 to rotate horizontally. The driving bevel gear then rotates accordingly, meshing with the driven bevel gear to convert the horizontal rotation into the vertical rotation of the lead screw 320. The rotation of the lead screw 320 drives... The lifting block 330 moves vertically downward along the lead screw 320, causing the mounting base 340 and the extruder 350 to move synchronously. The smooth circular end face of the extruder 350 contacts the lever 220 one by one, applying downward pressure. Since the strength of the second spring 360 is higher than that of the first spring 240, the lever 220 overcomes the elastic force of the first spring 240 and moves downward along the support rod, causing the blocking frame 230 to move synchronously, gradually opening the connecting hole 132. The seeds in the seed storage space enter the seed discharging trough through the connecting hole 132, then flow into the middle seed discharging space, and are discharged through the seed discharging box 120 and the seed discharging port 121. As the seeds are discharged into the field, the large and small isolation rings of the isolation ring 250 move with the lever 220, constantly isolating the seeds from the support rod to prevent jamming. Once the seeds at that height are discharged, the screw 320 drives the extruder 350 to continue moving downwards. The lever 220 is limited by the support 210, and the second spring 360 is compressed, causing the extruder 350 to disengage from the lever 220. The first spring 240 then returns to its elasticity, pushing the lever 220 back to its original position and closing the connecting hole 132. The extruder 350 continues to move downwards, controlled by the blocking frame 230, until all the seeds in that area are discharged. When the remaining seed level in the seed storage space is lower than the height of the lowest connecting hole 132, the operator drives the screw 520 to rotate by turning the handwheel 530, causing the connector 540 to lift the partition 130 and the mounting box 310. At this time, the first coupling disengages from the second coupling, the partition 130 rises and opens the bottom channel of the seed storage box 110, and the remaining seeds flow naturally into the seed discharge space and are discharged under the guidance of the funnel-shaped seed storage box 110. After the seeds in the seed storage box 110 are completely discharged, the handwheel 530 is turned in the opposite direction to reset the components, and the magnetic coupling 420 automatically adsorbs and restores power transmission.
