Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, and specifically relates to a clip-type seed supply device for a corn breeding weaving machine. Background Technology

[0002] Maize is a globally important food, feed, and industrial raw material crop. With its wide ecological adaptability and stable, high yield, it has become one of the core crops for alleviating food supply contradictions under the constraints of water and soil resources. The breeding and promotion of new maize varieties is key to improving production capacity, and small-plot breeding trials are a necessary step in variety screening and evaluation. These trials have extremely high requirements for uniformity of sowing depth, precise plant spacing, and no varietal mixing. Therefore, in production, a common practice is to first weave the seeds into ropes and then sow them uniformly.

[0003] Existing seed weaving machines are mostly designed for small vegetable seeds, and their seed-collecting mechanisms are ill-suited to the shape and agronomical requirements of corn seeds. Current seed supply devices generally lack intelligent control, relying on manual adjustment and experience for accuracy, resulting in low automation and frequent manual intervention. This not only increases the operational burden but also easily leads to seed-collecting chaos, preventing the same land from being reused within a short period and further reducing overall sowing efficiency. Taking the seed box outlet opening and closing mechanism as another example, some existing seed supply devices use paper doors, requiring the paper to be punctured to release the seeds. This easily results in paper scraps mixing with the seeds and entering the outlet slot, severely affecting the stability of seed supply. Furthermore, existing structures struggle to achieve continuous and orderly seed box supply, requiring frequent manual replacements, and their overall efficiency is ill-suited to the large-scale needs of corn breeding.

[0004] Existing seed weaving machines, such as the potato-specific seed weaving machine disclosed in patent number CN202510679115.6, have seed supply devices and seed suction devices adapted to the shape of potato hybrid seeds, which can meet the needs of supplying multiple seeds per hole. However, the stability of the supply amount depends entirely on manual adjustment and cannot meet the precision requirements of corn breeding. Summary of the Invention

[0005] To address the technical problems of low seed supply accuracy, poor continuity, easy clogging, and easy mixing of varieties in existing equipment, this invention proposes a clip-type seed supply device for corn breeding weaving machines that can improve seed weaving efficiency and stability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A clip-type seed supply device for a corn breeding weaving machine includes a seed box assembly, a seed box belt assembly, and a push rod assembly. The rear end of the seed box assembly is connected to the seed box belt assembly, and the push rod assembly is installed on the side. The seed box assembly includes a seed box, and an outlet groove, a belt drive device, a pin shaft recovery box, and a single-section seed box chain recovery box, all installed inside the seed box. Two first screws are arranged on the front of the seed box. The first screws pass through the outlet groove and the pin recovery box in sequence until the outlet groove abuts against the collar of the first screw. The outlet groove and the pin recovery box are separated by a retaining ring. The ends of the two first screws are locked with nuts to fix the position of the pin recovery box. The end of the outlet groove is connected to the seed outlet on the front of the seed box. Two second screws are arranged on the back of the seed box. The second screws pass through the single-section seed box chain recovery box and are locked with nuts. One side edge of the transmission belt of the belt drive device is connected to the top of the outlet groove, one end of the transmission belt is connected to one end of the inclined plate, and the other end is connected to the single-section seed box chain recycling box. The other end of the inclined plate overlaps at the seed box belt inlet on the rear end face of the seed box. The seed box has a push rod working port on the back side panel, and the color mark sensor is installed at the push rod working port facing the other side of the transmission belt.

[0007] Furthermore, the seed box and tape assembly includes a seed box and tape storage box, seed boxes and tapes arranged inside the storage box, and push rollers. The storage box is mounted on the rear end face of the seed box via a storage box support plate. The seed box and tape is composed of multiple detachable single-section seed box chains that are hinged together in sequence. Each single-section seed box chain has a T-shaped platform on one side. A disc-shaped slot is arranged on the side plate of the seed box and tape storage box. The T-shaped platform on the seed box and tape cooperates with the disc-shaped slot to disc-store the entire seed box and tape around the central axis of the storage box. The push rollers are mounted on the side plate of the seed box and tape storage box via push roller shafts. The push roller motor drives the push rollers to rotate, propelling the single-section seed box chains forward. A support platform for supporting the operation of the seed box and tape is welded to the side plate of the seed box and tape storage box. The front end of the support platform passes through the front end plate of the seed box and tape storage box until it overlaps with the seed box and tape inlet at the rear end face of the seed box.

[0008] Furthermore, each of the single-section seed box chains has a boss with a shaft hole at its rear end and a U-shaped groove at its front end. Both sides of the U-shaped groove have pin holes. After the boss of the previous single-section seed box chain is inserted into the U-shaped groove of the next single-section seed box chain, the hinge is completed by the pin shaft passing through the pin hole and the shaft hole.

[0009] Furthermore, each of the single-segment seed box chains has a color block at its rear end for detection by a color mark sensor.

[0010] Furthermore, each of the single-section seed box chains is equipped with a seed box, and the seed box slider is installed inside the seed box by a seed box spring. One end of the spring is fixed to the seed box slider, and the other end is fixed to the side plate of the seed box near the side plate of the seed box with the storage box. An electromagnet is installed on the top of the other side of the seed box, near the outlet. A folding door is installed at the outlet of the seed box and directly below the electromagnet. A magnet is installed at the top of the folding door, and the bottom is installed in the groove at the bottom of the seed box. The opening and closing of the folding door is achieved by the electromagnet attracting the magnet.

[0011] Furthermore, the push rod assembly includes a push rod box and a motor, as well as a working slider, a lead screw base, and a coupling, all arranged inside the push rod box. The push rod box is installed on the side of the seed box and is arranged on the same side as the transmission device. The output shaft of the motor is connected to one end of the lead screw through the coupling. The working slider is sleeved on the lead screw, and the other end of the lead screw is fixed to the lead screw base. One end of the smooth rod is fixed to the working slider, and the other end passes through the through hole of the lead screw base. The working slider is provided with a round rod that matches the seed box hole on the seed box. When the working slider moves, the round rod passes through the seed box hole and contacts the seed box slider, and the smooth rod aligns with the pin on the single-section seed box chain that reaches the working opening of the push rod.

[0012] Furthermore, an openable baffle is provided at the outlet of the pin recovery box.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention adopts a detachable seed box belt structure, and each seed box can be independently filled with different kinds of seeds, realizing flexible mixing of multiple varieties; it not only ensures high-speed and continuous seed supply capacity, but also improves the diversity and adaptability of sowing.

[0014] 2. The seed box of this invention is stored in a tray in the storage box, which greatly improves the space utilization rate. With the coordinated conveying of the push wheel and belt drive, the orderly and continuous supply of seed boxes can be achieved.

[0015] 3. The seed box of this invention uses an electromagnetic folding door to control the opening and closing of the outlet. The electromagnetic folding door not only realizes intelligent control, but also avoids paper scraps when the paper door is punctured, preventing paper scraps from mixing into the seeds and entering the outlet slot, thereby effectively improving the seed supply efficiency and stability.

[0016] 4. This invention features an independent pin shaft recycling box and a single-section seed box chain recycling box, eliminating the need for overall recycling of the seed box belt. This reduces the risk of structural damage during the recycling process and facilitates the disassembly and reloading of individual seed boxes and the rapid reassembly of the seed box belt, significantly improving operational efficiency.

Detailed Implementation

[0018] The specific structure and working process of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0019] like Figure 1 The clip-type seed supply device shown for a corn breeding weaving machine includes a seed box assembly 1, a seed box belt assembly 2, and a push rod assembly 3. The rear end of the seed box assembly 1 is connected to the seed box belt assembly 2, and the push rod assembly 3 is mounted on the side.

[0020] The specific structure of seed box assembly 1 is as follows: Figures 2 to 4 As shown, it includes a seed box 101, and an outlet trough 102, a belt drive device 103, a pin shaft recycling box 104, a single-section seed box chain recycling box 105, and a color mark sensor 110, all installed in the seed box 101.

[0021] Two first screws are arranged on the front of the seed box 101. The first screws pass through the outlet groove 102 and the pin recovery box 104 in sequence until the outlet groove 102 abuts against the collar 113 of the first screw. The outlet groove 102 and the pin recovery box 104 are separated by a retaining ring 114. The ends of the two first screws are locked with nuts to fix the position of the pin recovery box 104. An openable baffle 115 is arranged at the outlet of the pin recovery box 104 to facilitate the centralized cleaning of the recovered pins. The end of the outlet groove 102 is directly connected to the seed outlet 106 on the front of the seed box 101 to ensure that the seed conveying path is complete. Two second screws are arranged on the back of the seed box 101. The second screws pass through the single-section seed box chain recovery box 105 and are locked with nuts to achieve a stable installation of the recovery box.

[0022] The belt drive device 103 includes a driving pulley, a driven pulley, a driving shaft, a driven shaft, and a drive belt. The driving shaft passes through the driving pulley and is mounted on the back side plate of the seed box 101. Similarly, the driven shaft passes through the driven pulley and is mounted on the back side plate of the seed box 101. The drive belt is fitted onto the driving pulley and the driven pulley. One side edge of the drive belt is connected to the top of the outlet trough 102 to ensure that no seeds spill when falling into the outlet trough. One end of the drive belt is connected to one end of the inclined plate 108, and the other end is connected to the single-section seed box chain recycling box 105 (to separate the seeds). A single-section seed box chain is conveyed into a single-section seed box chain recycling box 105. The other end of the inclined plate 108 overlaps with the seed box belt inlet 107 on the rear end face of the seed box 101, forming a conveying guide path for the seed box belt. A push rod working port 109 is opened on the back side plate of the seed box 101. A color mark sensor 110 is installed at the push rod working port 109 and faces the other side of the transmission belt to detect the color blocks of the passing seed box chain. To facilitate observation of the internal operating status, the front door 112 and the top door 111 of the seed box 101 are both made of transparent plastic.

[0023] Combination Figure 5 , Figure 6 , Figure 7 , Figure 8The seed cassette assembly 2 shown includes a seed cassette storage box 201, seed cassettes 202 and push rollers 205 arranged in the seed cassette storage box 201, and the seed cassette storage box 201 is installed on the rear end face of the seed box 101 through a storage box support plate. The seed box belt 202 is composed of multiple detachable single-section seed box chains 208 that are hinged together in sequence. Each single-section seed box chain 208 has a boss 210 with a shaft hole at its rear end (the pin holes 213 on both sides of the U-shaped groove 212 of each single-section seed box chain 208 do not interfere with the T-shaped platform 209), and a U-shaped groove 212 at its front end. Both sides of the U-shaped groove 212 have pin holes 213. After the boss 210 of the previous single-section seed box chain 208 is inserted into the U-shaped groove 212 of the next single-section seed box chain 208, the hinge is completed by the pin 211 passing through the pin hole 213 and the shaft hole. This connection method ensures that the seed box belt can be flexibly bent, while meeting the tensile requirements of the conveying process. Each individual seed box chain 208 has a T-shaped platform 209 on one side, and a disc-shaped slot 214 is arranged on the side plate of the seed box storage box 201. The T-shaped platform 209 on the seed box chain 202 cooperates with the disc-shaped slot 214 to store the entire seed box chain 202 around the central axis 215 of the storage box, greatly improving the storage density. Each individual seed box chain 208 has a color block at the rear end for detection by the color mark sensor 110. The push wheel 205 is mounted on the side of the seed box chain storage box 201 via the push wheel shaft 204. On the plate, the pusher motor drives the pusher 205 to rotate, which in turn moves the single seed box chain 208 forward. A support platform 206 for supporting the operation of the seed box chain 202 is welded to the side plate of the seed box chain storage box 201. The front end of the support platform 206 passes through the front end plate of the seed box chain storage box 201 and connects to the seed box chain inlet 107 at the rear end of the seed box 101, providing support for the seed box chain conveying. The seed box chain 202 enters the seed box assembly 1 from the seed box chain storage box 201 through the seed box chain inlet 107.

[0024] Each single-section seed box chain 208 contains a seed box 203 installed via a snap-fit ​​mechanism. A seed box slider 215 is installed inside the seed box 203 via a seed box spring 216. One end of the spring 216 is fixed to the seed box slider 215, and the other end is fixed to a side plate of the seed box 203 near the side plate of the seed box with storage box 201. An electromagnet 217 is installed on the top of the other side of the seed box 203, near the outlet. A folding door 218 is installed at the outlet of the seed box 203, directly below the electromagnet 217. A magnet is installed at the top of the folding door 218, and the bottom is installed in a groove at the bottom of the seed box 203. The folding door 218 is opened and closed by the electromagnet 217 attracting the magnet. To facilitate observation of the remaining amount of seeds in the seed box, the seed box lid of the seed box 203 and the seed box with storage box door 207 are both made of transparent plastic.

[0025] like Figure 9The push rod assembly 3 shown includes a push rod box 301 and a motor 302, as well as a working slider 304, a lead screw base 305, and a coupling 303, all arranged within the push rod box 301. The push rod box 301 is mounted on the side of the seed box 101 and is arranged on the same side as the transmission device. The output shaft of the motor 302 is connected to one end of the lead screw 307 via the coupling 303. The working slider 304 is sleeved on the lead screw 307, and the other end of the lead screw 307 is fixed to the lead screw base 305. One end of the smooth rod 308 is fixed to the working slider 304, and the other end passes through the through hole of the lead screw base 305. The working slider 304 is provided with a round rod 306 that matches the seed box hole 219 on the seed box 203. When the working slider 304 moves, the round rod 306 can pass through the seed box hole 219 to contact the seed box slider 215, and the smooth rod 308 is aligned with the pin 211 on the single-section seed box chain 208 that reaches the push rod working opening 109. It should be noted that the axis of the pin 211 of the single seed box chain 208 is perpendicular to the direction of the seed box belt conveyor, and the axis of the smooth rod 308 of the push rod assembly 3 is strictly collinear with the axis of the pin 211. A single push rod action can simultaneously complete the two processes of pushing out the seed and ejecting the pin, which greatly simplifies the execution steps. Specifically: Motor 302 drives lead screw 307 to rotate, lead screw 307 drives working slider 304 to move, working slider 304 pushes smooth rod 308 to move through push rod working opening 109 of seed box 101 until it is aligned with pin 211 on single-section seed box chain 208 at push rod working opening 109. At the same time, round rod 306 on working slider 304 is aligned with seed box hole 219 on seed box 203. Motor 302 continues to drive lead screw 307 to rotate, lead screw 307 continues to drive working slider 304 to move, working slider 304 continues to push smooth rod 308 to move and push pin 211 out of pin hole and shaft hole on single-section seed box chain. Round rod 306 on working slider 304 passes through seed box hole 219 and pushes seed box slider 215 to push seeds out of seed box.

[0026] Overall seed handling process: Corn seeds are placed into each seed box 203 in a certain quantity. Single seed box chains 208 are assembled into a complete seed box belt 202 via pins 211. The T-shaped platform 209 of the seed box belt 202 is then inserted into the disc-type slot 214 and coiled around the central shaft 215 of the storage box. The pusher motor is started, and the pusher 205 rotates, causing the seed box 203 to be conveyed forward along the support platform 206. The seed box belt 202 passes sequentially through the front end plate of the seed box belt storage box 201, the seed box belt inlet 107 on the seed box 101, and enters the drive belt of the belt drive device 103 via the inclined plate 108. The belt drive motor is started, driving the drive shaft to make the belt drive device 103 run counterclockwise, continuously conveying the seed box belt 202 towards the pusher working port 109. When the color mark sensor 110 detects the color block signal of a single seed box chain 208, the belt drive motor immediately stops. At this time, the round rod 306 on the working slider 304 is aligned with the seed box hole 219 of the seed box 203, and the smooth rod 308 is aligned with the pin 211 of the adjacent seed box chain. The screw motor is started, driving the working slider 304 to move towards the transmission belt. At the same time, the electromagnet 217 inside the seed box 203 is de-energized, and the folding door 218 loses its attraction force and flips downward to open. The round rod 306 on the working slider 304 passes through the seed box hole 219 and pushes the seed box slider 215 to push the seeds in the seed box into the outlet groove 102. The seeds reach the seed outlet 106 along the outlet groove 102 and enter the subsequent weaving stage. At the same time, the smooth rod 308 pushes the pin 211 out of the pin hole 213 of the U-shaped groove 212. The pin 211 falls into the connection key recycling box 104 below, completing the disassembly of the current single seed box chain.

[0027] Corn seeds pass through outlet 102 to seed outlet 106. After the corn seeds in seed box 203 are exhausted, the motor reverses, the working slider 304 resets, the round rod 306 exits the seed box hole 219, the seed box spring 216 drives the seed box slider 215 back to its original position, and the electromagnet 217 is re-energized to attract the magnet on the folding door 218, closing the seed box outlet. Then, the belt drive motor is started, the belt continues to run, and the belt drive device 103 transports the next seed box 203 to the push rod working port 109. At the same time, the separated single-section seed box chain 208 continues to be transported forward into the single-section seed box chain recycling box 105. Repeating the above process achieves continuous and automated seed supply.

[0028] The motors, pusher motors, and all other motors in the aforementioned transmission device are conventional motors, and the logic control is also conventional electronic control. The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
