Description

Technical Field

[0001] This utility model relates to the field of breeding equipment technology, and in particular to a high-purity wind-selection breeding device for wheat seeds. Background Technology

[0002] Wheat is a common grain crop. Before planting wheat, in order to improve the quality of wheat seeds and increase wheat yield, it is necessary to select wheat seeds, that is, to select plump wheat seeds from wheat seeds using wheat breeding and selection devices.

[0003] A search revealed that an existing patent with authorization number CN216705109U discloses a wheat breeding and selection device. The device includes a shell with an inlet, a guide shell inside the shell, a seed collection port on the guide shell, and a blower between the seed collection port and the inlet. A reciprocating filter assembly is located at the bottom of the shell. In use, the blower is started and wheat seeds are poured into the inlet. As the wheat seeds fall, the blower blows away the chaff inside the seeds. The wheat seeds after the chaff is blown away fall onto the reciprocating filter assembly for filtration, removing sand and shriveled wheat seeds, thus completing the wheat selection process.

[0004] The above-mentioned patent has the following problems when in use: When in use, there is no intermittent feeding device at the inlet. After the wheat seeds are poured into the inlet, they will pass through the seed collection port and the inlet in a concentrated manner. The blower's wind force is applied for a very short time, which affects the blowing effect. Moreover, the reciprocating filter component selects seeds by the process of the wheat seeds rolling on the filter plate. The wheat seeds are screened on the filter plate for a short time, which has an adverse effect on the screening quality and screening efficiency. There is room for improvement.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-purity wind-selection breeding device for wheat seeds.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A high-purity wheat seed air separation breeding device includes a base plate, a wheat breeding machine housing, a control module, and a drive mechanism;

[0009] The base plate is equipped with a wheat breeding machine housing, which is equipped with a drive mechanism and a control module. The drive mechanism is connected to the control module. The top of the wheat breeding machine housing is equipped with a wheat feed hopper, which contains a stirring component connected to the drive mechanism. A partition is fixedly connected inside the wheat breeding machine housing, and a wheat air separator and a fan are fixedly installed on the partition. The fan is connected to the wheat air separator. A wheat screening frame is slidably connected between the partition and the wheat breeding machine housing. The wheat screening frame is connected to the drive mechanism. Through the coordinated design of the wheat breeding machine housing, control module, fan, wheat air separator, wheat screening frame, drive mechanism, and stirring component, not only can the purpose of air separating wheat be achieved, but also the effect of intermittent feeding of wheat can be achieved, allowing wheat to be air separated and screened in batches. This allows for longer air separation and screening time, more thorough screening, and improved wheat breeding quality. It also prevents the wheat after air separation from clogging the wheat screening frame.

[0010] Preferably, the drive mechanism includes a motor, a rotating shaft, a first cam, a sealing plate, a slide rail, a first gear, a second gear, a second cam, and an impact rod. The motor is fixedly mounted on the top of the wheat breeding machine housing. The output end of the motor is fixedly connected to the rotating shaft. The rotating shaft is rotatably connected to both the wheat breeding machine housing and the partition plate. A first cam is fixedly connected to the rotating shaft, and a sealing plate is contacted and connected to the first cam. The sealing plate is slidably connected to the wheat breeding machine housing. Slide rails are slidably connected to both sides of the sealing plate. Both slide rails are fixedly connected to the wheat breeding machine housing. The drive mechanism is operated by the motor... The machine's drive, along with the transmission of the rotating shaft and the first cam, causes the first cam to interact with the sealing plate, resulting in the sealing plate sliding a certain distance to the right on the two slide rails. This compresses the second spring, aligning the second discharge port on the sealing plate with the first discharge port on the top of the wheat breeding machine housing. Simultaneously, wheat passes through the first and second discharge ports and falls into the wheat air separator. Then, the elastic potential energy of the second spring causes the sealing plate to return to its original shape, sealing the first discharge port and thus achieving intermittent wheat feeding.

[0011] Preferably, the wheat breeding machine housing has a first feeding port and the sealing plate has a second feeding port. The first feeding port corresponds to the wheat feeding hopper, and the second feeding port corresponds to the first feeding port. A second spring is fixedly connected to one end of the sealing plate, and one end of the second spring is fixedly connected to the wheat breeding machine housing. A first through hole is provided on the sealing plate, and the wheat in the wheat feeding hopper passes through the first and second feeding ports and falls into the wheat air separator.

[0012] Preferably, the stirring assembly includes a stirring rod, a gear three, and a rack. The stirring rod is rotatably connected to the wheat breeding machine housing. The stirring rod is adapted to the wheat feed hopper. One end of the stirring rod extends into the through hole one and is fixedly connected to the gear three. The gear three is meshed with the rack. The rack is fixedly installed in the through hole one and is slidably connected to the wheat breeding machine housing. During the sliding process of the sealing plate, the rack moves synchronously. At the same time, the rack and the gear three drive the stirring rod to rotate on the wheat breeding machine housing. In this process, the stirring rod stirs the wheat in the wheat feed hopper, thereby ensuring the fluidity of the wheat and allowing it to pass smoothly through the discharge port one and discharge port two during feeding.

[0013] Preferably, a gear 1 is fixedly connected to the rotating shaft, a gear 2 is meshed with the gear 1, and a fixed rod 1 is fixedly connected to the gear 2. The fixed rod 1 is rotatably connected to both the partition and the wheat breeding machine housing. A cam 2 is fixedly connected to the fixed rod 1. A fixed plate 1 is fixedly connected between the partition and the wheat breeding machine housing. An impact rod is slidably connected to the fixed plate 1. One end of the impact rod corresponds to the cam 2, and the other end of the impact rod contacts the wheat screening frame. Through the transmission between the gear 1 and the gear 2, the fixed rod 1 rotates on the partition and the wheat breeding machine housing. At the same time, the fixed rod 1 drives the cam 2 to rotate synchronously, causing the cam 2 to interact with the impact rod. This causes the impact rod to slide on the fixed plate 1 and impact the wheat screening frame. Under the elastic potential energy of the multiple springs 1, the wheat screening frame vibrates, thereby preventing the wheat after wind separation from clogging the wheat screening frame.

[0014] Preferably, a plurality of springs are fixedly connected to one side of the wheat screening frame, and one end of each of the plurality of springs is fixedly connected to the housing of the wheat breeding machine. The elastic potential energy of the plurality of springs causes the wheat screening frame to return to its original shape. A discharge port is provided at the bottom of the housing of the wheat breeding machine, which corresponds to the wheat screening frame and is used to discharge wheat seeds.

[0015] Preferably, the bottom plate is provided with a collection box, which corresponds to the discharge port and is used to collect wheat seeds.

[0016] Preferably, both the electric motor and the fan are connected to the control module, and the control module drives and controls the fan and the electric motor.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model discloses a high-purity wheat seed air-separation breeding device. Driven by an electric motor and transmitted through a rotating shaft and a first cam, the first cam interacts with a sealing plate, causing the sealing plate to slide a certain distance to the right on two slide rails. This compresses the second spring, aligning the second discharge port on the sealing plate with the first discharge port on the top of the wheat breeding machine housing. At this time, wheat in the wheat feed hopper passes through the first and second discharge ports and falls into the wheat air-separation box, achieving intermittent feeding of wheat. This allows for batch-wise air-separation and screening, extending the air-separation and screening time, ensuring more thorough screening, and improving the quality of wheat breeding.

[0019] This utility model discloses a high-purity wheat seed air-selection breeding device. During the sliding process of the sealing plate, the rack moves synchronously. At the same time, the rack and the gear three drive the stirring rod to rotate on the wheat breeding machine housing. During this process, the stirring rod stirs the wheat in the wheat feed hopper, thereby ensuring the fluidity of the wheat and allowing it to pass smoothly through the first and second feed ports when being fed.

[0020] This utility model discloses a high-purity wheat seed air-separation breeding device. Through the transmission between gear one and gear two, the fixed rod one rotates on the partition plate and the wheat breeding machine housing. At the same time, the fixed rod one drives the cam two to rotate synchronously, and the cam two interacts with the impact rod. This causes the impact rod to slide on the fixed plate one and impact the wheat screening frame. Under the action of the elastic potential energy of multiple springs one, the wheat screening frame vibrates, thereby achieving the effect of preventing the wheat after air separation from clogging the wheat screening frame.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides a high-purity wind-selection breeding device for wheat seeds, referring to... Figure 1-5 A high-purity wheat seed air separation breeding device includes a base plate 1, a wheat breeding machine housing 2, a control module 14, and a drive mechanism 7;

[0030] A wheat breeding machine housing 2 is mounted on a base plate 1. A drive mechanism 7 and a control module 14 are mounted on the housing 2. The drive mechanism 7 is connected to the control module 14. A wheat feed hopper 3 is located on the top of the housing 2. A stirring assembly is located inside the feed hopper 3 and connected to the drive mechanism 7. A partition 4 is fixedly connected inside the housing 2. A wheat air separator 5 and a blower 6 are fixedly mounted on the partition 4. The blower 6 is connected to the wheat air separator 5. A wheat sieve is slidably connected between the partition 4 and the housing 2. The selection frame 8, which is connected to the drive mechanism 7, is designed in conjunction with the wheat breeding machine housing 2, control module 14, fan 6, wheat air separation box 5, wheat selection frame 8, drive mechanism, and stirring components. This design not only enables the air separation of wheat but also allows for intermittent feeding of wheat, allowing for batch air separation and screening. This results in longer air separation and screening times, more thorough screening, improved wheat breeding quality, and prevents the wheat selection frame 8 from clogging after air separation.

[0031] In this configuration, the drive mechanism 7 includes a motor 71, a rotating shaft 72, a first cam 73, a sealing plate 74, a slide rail 75, a first gear 76, a second gear 77, a second cam 78, and an impact rod 79. The motor 71 is fixedly mounted on the top of the wheat breeding machine housing 2. The output end of the motor 71 is fixedly connected to the rotating shaft 72. The rotating shaft 72 is rotatably connected to both the wheat breeding machine housing 2 and the partition plate 4. A first cam 73 is fixedly connected to the rotating shaft 72. A sealing plate 74 is contacted and connected to the first cam 73. The sealing plate 74 is slidably connected to the wheat breeding machine housing 2. Slide rails 75 are slidably connected to both sides of the sealing plate 74. Both slide rails 75 are fixedly connected to the wheat breeding machine housing 2. The motor 71 drives the drive mechanism 79. Driven by 1 and driven by the rotating shaft 72 and the cam 73, the cam 73 interacts with the sealing plate 74, causing the sealing plate 74 to slide a certain distance to the right on the two slide rails 75, compressing the spring 15, and aligning the discharge port 2 on the sealing plate 74 with the discharge port 1 at the top of the wheat breeder housing 2. At the same time, wheat passes through the discharge port 1 and discharge port 2 and falls into the wheat air separator 5. Then, the elastic potential energy of the spring 15 causes the sealing plate 74 to return to its original shape and seal the discharge port 1, thereby achieving the effect of intermittent wheat feeding. The wheat breeder housing 2 is tilted at a certain angle to facilitate the movement of wheat in the wheat feed hopper 3 towards the discharge port 1.

[0032] In this method, a first feeding port is provided on the housing 2 of the wheat breeding machine, and a second feeding port is provided on the sealing plate 74. The first feeding port corresponds to the wheat feeding hopper 3, and the second feeding port corresponds to the first feeding port. A second spring 15 is fixedly connected to one end of the sealing plate 74, and one end of the second spring 15 is fixedly connected to the housing 2 of the wheat breeding machine. A first through hole is provided on the sealing plate 74. The wheat in the wheat feeding hopper 3 passes through the first and second feeding ports and falls into the wheat air separator 5.

[0033] In this method, the stirring assembly includes a stirring rod 11, a gear 12, and a rack 13. The stirring rod 11 is rotatably connected to the wheat breeding machine housing 2. The stirring rod 11 is adapted to the wheat feed hopper 3. One end of the stirring rod 11 extends into the through hole 1 and is fixedly connected to the gear 12. The gear 12 is meshed with the rack 13. The rack 13 is fixedly installed in the through hole 1 and is slidably connected to the wheat breeding machine housing 2. During the sliding process of the sealing plate 74, the rack 13 is driven to move synchronously. At the same time, the rack 13 and the gear 12 drive the stirring rod 11 to rotate on the wheat breeding machine housing 2. During this process, the stirring rod 11 stirs the wheat in the wheat feed hopper 3, thereby ensuring the fluidity of the wheat and allowing the wheat to pass smoothly through the discharge port 1 and discharge port 2 when it is fed.

[0034] In this method, a gear 76 is fixedly connected to the rotating shaft 72, a gear 77 is meshed with the gear 76, and a fixed rod is fixedly connected to the gear 77. The fixed rod is rotatably connected to the partition 4 and the wheat breeding machine housing 2. A cam 78 is fixedly connected to the fixed rod. The same fixed plate is fixedly connected between the partition 4 and the wheat breeding machine housing 2. An impact rod 79 is slidably connected to the fixed plate. One end of the impact rod 79 corresponds to the cam 78, and the other end of the impact rod 79 contacts the wheat screening frame 8. Through the transmission between the gear 76 and the gear 77, the fixed rod rotates on the partition 4 and the wheat breeding machine housing 2. At the same time, the fixed rod drives the cam 78 to rotate synchronously, and the cam 78 interacts with the impact rod 79. This causes the impact rod 79 to slide on the fixed plate and impact the wheat screening frame 8. Under the action of the elastic potential energy of multiple springs 9, the wheat screening frame 8 vibrates, thereby preventing the wheat after wind separation from clogging the wheat screening frame 8.

[0035] In this method, a plurality of springs 9 are fixedly connected to one side of the wheat screening frame 8. One end of each spring 9 is fixedly connected to the wheat breeding machine housing 2. The elastic potential energy of the multiple springs 9 causes the wheat screening frame 8 to return to its original shape. A discharge port is provided at the bottom of the wheat breeding machine housing 2, which corresponds to the wheat screening frame 8 and is used to discharge wheat seeds.

[0036] In this method, a collection box 10 is provided on the base plate 1, which corresponds to the discharge port and is used to collect wheat seeds.

[0037] In this method, both the motor 71 and the fan 6 are connected to the control module 14, and the control module 14 drives and controls the fan 6 and the motor 71.

[0038] Working principle: During use, the fan 6 and the motor 71 are driven and controlled by the control module 14;

[0039] First, wheat is poured into the wheat feed hopper 3. Then, the motor 71 and the fan 6 are started. At this time, the motor 71 drives the rotating shaft 72 to rotate on the wheat breeding machine housing 2. Simultaneously, the rotating shaft 72 drives the cam 73 and gear 76 to rotate synchronously. During this process, the cam 73 interacts with the sealing plate 74, causing the sealing plate 74 to slide a certain distance to the right on the two slide rails 75. This compresses the spring 15 and aligns the discharge port 2 on the sealing plate 74 with the discharge port 1 at the top of the wheat breeding machine housing 2. At this time, the wheat in the wheat feed hopper 3 passes through the discharge port 1 and discharge port 2 and falls into the wheat air separator 5, thus achieving the effect of intermittent feeding of wheat. This allows the wheat to be air-separated and screened in batches, which can extend the air separation and screening time, make the screening more thorough, and improve the quality of wheat breeding.

[0040] While the sealing plate 74 slides, it drives the rack 13 to move synchronously. At the same time, the rack 13 and the gear 12 drive the stirring rod 11 to rotate on the wheat breeding machine housing 2. During this process, the stirring rod 11 stirs the wheat in the wheat feed hopper 3 to ensure the fluidity of the wheat, so that the wheat can pass smoothly through the feed port 1 and feed port 2 when it is fed.

[0041] In this process, the wheat is air-separated by the cooperation between the blower 6 and the wheat air separation box 5.

[0042] Afterwards, the wheat that has been winnowed falls into the wheat screening frame 8. At the same time, gear 1 76 and gear 2 77 drive each other, causing the fixed rod 1 to rotate on the partition 4 and the wheat breeding machine housing 2. Simultaneously, the fixed rod 1 drives the cam 2 78 to rotate synchronously, causing the cam 2 78 to act on the impact rod 79. This causes the impact rod 79 to slide on the fixed plate 1 and impact the wheat screening frame 8, causing the wheat screening frame 8 to slide a certain distance between the wheat breeding machine housing 2 and the partition 4. This compresses multiple springs 1 9. Then, when the cam 2 78 disengages from the impact rod 79, the force of the multiple springs 1 9 causes the wheat screening frame 8 to return to its original shape. During this process, the wheat screening frame 8 vibrates, thereby preventing the winnowed wheat from clogging the wheat screening frame 8.

[0043] Finally, the screened wheat passes through the discharge port below the wheat breeding machine housing 2 and falls into the collection box 10, thereby achieving the effect of collecting the screened wheat.

[0044] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, not only can the purpose of wind selection of wheat be achieved, but also the effect of intermittent feeding of wheat can be achieved, allowing wheat to be wind-selected and screened in batches. This allows for longer wind selection and screening times, more thorough screening, and improved quality of wheat breeding. Furthermore, it can prevent the wheat after wind selection from clogging the wheat screening frame 8, greatly enhancing its practicality.

[0045] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
