Description

Technical Field

[0001] The invention belongs to the technical field of plant variety processing, and specifically discloses a seed collecting device. Background Art

[0002] Common leguminous crops usually include soybeans, mung beans, peas, broad beans, etc. These leguminous crops are usually low shrubs, and the seeds are wrapped in pods for growth. When the seeds mature, the pods will be squeezed. At this time, because the pods are full of water and have a certain shrinkage, the leguminous seeds will still be wrapped. Leguminous seeds are generally harvested after the seeds mature. The whole crop is cut and dried. The moisture of the roots, stems, leaves and pods of leguminous crops will evaporate during the drying process. After the moisture of the pods evaporates, the seeds squeeze the pods, causing them to burst. At this time, the seeds can be collected.

[0003] At present, the collection of seeds is done by beating the whole leguminous crop after most of the water in all the pods has evaporated, so that all the pods burst and the seeds fall out, and then the seeds are separated from the crushed crops for collection. This process is mostly done manually, which is very time-consuming and labor-intensive. At the same time, the seeds are mixed with the crushed roots, stems, leaves and pods, and the labor intensity of separation is high. In addition, the separated seeds will be adhered to the debris of roots, stems, leaves and pods, and need to be cleaned multiple times. Summary of the invention

[0004] The purpose of the present invention is to provide a seed collecting device to solve the problem that collecting leguminous seeds is time-consuming and labor-intensive and requires multiple cleanings.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the present invention is as follows: a seed collecting device comprises a box body and a frame, the box body is fixed on the frame, a cavity is arranged inside the box body, the cavity is cylindrical, a feed port connected to the cavity is arranged on the side wall of the box body, a baffle door is detachably connected to the feed port, a layer of wire mesh is arranged around the cavity, the wire mesh and the inner wall of the cavity form a seed collecting cavity, a collecting tube connected to the seed collecting cavity is arranged at the lower part of the box body, a plurality of baffles made of soft rubber are arranged in all the grids of the wire mesh, and the grids of the wire mesh are covered with the plurality of baffles;

[0006] The upper end of the box body is provided with a blind hole, a shaft is rotatably connected in the blind hole, an impeller is fixed on the shaft, and a plurality of clamping units for clamping leguminous plants are provided on the upper part of the shaft; an annular cavity connected to the outside and located outside the blind hole is provided on the upper part of the box body, an air inlet pipe connected to the cavity through the annular cavity is provided on the outside of the box body, a plurality of electric heating pipes are distributed inside the air inlet pipe, and electric heating wires are embedded inside the wire mesh;

[0007] The lower end of the cavity is provided with an annular plate that fits the inner part of the lower end of the wire mesh, and a rotating rod is provided in the annular plate, and an annular groove is provided on the inner side of the upper part of the annular plate, and two ends of the rotating rod are slidably connected in the annular groove; a key groove is provided on the rotating rod at the center of the annular plate, and a key rod is provided at the lower end of the shaft rod that extends into the key groove and engages with it, and a rolling roller is rotatably provided on the rotating rod; a rotating disk is slidably connected with a leakage hole smaller than the seed diameter on the inner middle and lower parts of the annular plate, and a pipeline is connected at the lower end of the annular plate, and a filter tube is detachably connected at the lower part of the pipeline; a plurality of through holes connected with the seed collecting chamber are provided at the lower part of the annular plate; a magnetic ring is provided at the edge of the upper end of the rotating disk, and an electromagnet that attracts the magnetic ring when power is turned on is provided in the middle of the annular plate; a key hole is provided at the center of the rotating disk, and a short rod is rotatably connected to the key hole at the lower end of the key rod, and a key block is provided at the lower end of the short rod that extends into the key hole and engages with it, and the length of the short rod is equal to the vertical distance between the key rod and the through hole.

[0008] The working principle of this basic scheme is: when the bean shell plants are mature and harvested, the baffle can be opened, a handful of legumes can be placed upside down in the box of this device, and the cut parts of the legumes can be clamped using the clamping unit. After the legumes are clamped on the clamping units, the baffle is closed. The electric heating tube, the electric heating wire and the electromagnet are energized, and the exhaust fan is used to extract air at the filter tube. The air will enter the cavity through the air inlet pipe and be extracted through the pipe and the filter tube. The air will be heated by the electric heating tube before entering the cavity and become hot air to enter the inner cavity. The electric heating wire can heat the legumes in the cavity; the hot air entering the cavity will be discharged through the pipe. During the process of hot air being discharged through the pipe, small debris will be discharged through the leak hole of the turntable, and the filter tube will filter the discharged hot air.

[0009] In the above process, the hot air will dry the legumes, and the roots, stems, leaves and pods of the legumes will quickly draw out moisture in the hot air flow. The pods will shrink after losing water and drying, but the water content of the seeds themselves is not high. Since they lose less water during the drying process when wrapped in the pods, their volume will not shrink too much. During the process of pod loss of water and shrinkage, the seeds will squeeze the pods to break them and pop out of the pods. After the seeds pop out, if they are not ejected in a vertical direction, they will be ejected onto the wire mesh and enter the seed collection chamber through the baffle. Some seeds will fall onto the turntable. Since the leakage hole is smaller than the diameter of the seeds, the seeds will not flow with the hot air through the leakage hole during the hot air flow. When the electromagnet is energized, it will adsorb the magnetic ring, so that the turntable moves up in the annular plate, and the surroundings of the turntable will not be aligned with the position where the through hole is provided at the bottom of the annular plate, and the seeds will not enter the seed collection chamber through the through hole.

[0010] After most of the moisture in the roots, stems, leaves and pods of the legumes is removed, the clamping unit is controlled to release the clamping of the legumes, and the legumes will fall onto the turntable. During the hot air flow, the impeller will rotate under the action of the hot air, thereby rotating the shaft, and the rotation of the shaft will drive the short rod and the key rod to rotate, thereby rotating the rotating rod. During the rotation of the rotating rod, the two ends of the rotating rod slide in the annular groove, so that the rotating rod always keeps rotating horizontally. Since the short rod is rotatably connected to the key hole, the length of the short rod is equal to the vertical distance between the key rod and the through hole. At this time, the short rod is aligned with the key hole, so that the turntable does not rotate. The outer rotation of the rotating rod is provided with a crushing wheel, which will rotate horizontally with the rotating rod, so that the crushing wheel crushes the dried legumes on the turntable, and the plant debris produced by the crushing will be taken away by the hot air through the leakage hole; after this process continues for a period of time, the roots, stems, leaves and pods of the legumes are basically crushed and discharged with the hot air.

[0011] At this time, the electromagnet is powered off, and the turntable will move downward under its own gravity. The seeds that have not leaked out through the leak hole and are carried away by the hot air will enter the seed collection chamber through the through hole, and individual seeds can be collected through the collection tube. At the same time, after the turntable moves downward, the through hole will be located around the upper end of the turntable, and the key hole will engage with the key block. Under the driving action of the shaft rod, the key block will rotate accordingly, thereby driving the turntable to rotate; so that the seeds will perform centrifugal motion on the turntable, which is more conducive to the seeds being thrown to the edge under the centrifugal force and entering the seed collection chamber through the through hole. Since the power of the hot air flow comes from the filter tube, the continuous use of the exhaust fan will cause the shaft rod to rotate continuously, and the pipeline is connected to the lower end of the annular plate. The hot air is mainly sucked out through the pipeline, thereby preventing the hot air from entering the seed collection chamber, so that the dust and debris of the leguminous plants enter the seed collection chamber with the seeds and contaminate the collected seeds. Some roots, stems, leaves and pods of leguminous plants that cannot be crushed can be taken out after all the seeds on the turntable have entered the seed collection unit by turning off the exhaust fan and opening the baffle door, and then the next leguminous plant seed collection operation can be carried out.

[0012] The beneficial effects of this basic scheme are:

[0013] 1. No manual operation is required, which saves a lot of labor, time and effort. It can quickly separate and collect the seeds on leguminous plants. This kind of collection prevents the debris of leguminous plants from adhering to the seeds, thereby reducing the number of seed cleaning times.

[0014] 2. During the seed collection process, the roots, stems, leaves and pods of legumes are dried, crushed and sucked out. The relatively fine fragments of the roots, stems, leaves and pods of legumes can be collected from the filter tube and can be reused as feed, etc., which greatly saves resources.

[0015] 3. The device dries and removes dust from the seeds, making it easier to clean and preserve the seeds.

[0016] Compared with the prior art, the device saves time and effort in collecting leguminous seeds and does not require multiple cleanings.

[0017] Furthermore, the clamping unit includes a bottom block and two clamping claws arranged perpendicular to the shaft rod, the bottom block is fixed on the shaft rod, a rectangular frame is provided in the middle of the bottom block, and a sliding cavity is provided inside the bottom block; sliding rods sliding with the sliding cavity are respectively provided on both sides of the rectangular frame in the horizontal direction, and the two sliding rods are symmetrically arranged, and a sliding block slidingly connected to the sliding cavity is provided at the lower part of the bottom block, the clamping claw is fixed at one end of the sliding rod away from the sliding cavity, the clamping claw is arc-shaped, and the concave sides of the two clamping claws are arranged opposite to each other; an elastic member for pulling the sliding block is provided in the sliding cavity.

[0018] When the clamping unit is used to clamp the leguminous plant, the slider is pulled downward to transfer the air in the sliding cavity so that the two slide bars move into the sliding cavity, and the ends of the two slide bars away from the sliding cavity move away from each other, so that the two clamping claws are separated; the leguminous plant is placed between the two clamping claws, and the downward pull on the slider is released. The slider moves upward under the elastic force of the elastic member, and the air in the sliding cavity is transferred to make the two slide bars extend out of the sliding cavity, and the ends of the two slide bars away from the sliding cavity move closer to each other, so that the two clamping claws move closer to grab the leguminous plant. This structure is simple to operate and easy to use, and can clamp the leguminous plant more firmly.

[0019] Furthermore, the blocking piece is triangular, one side of the blocking piece is connected to one side of the grid, and the elastic member is a tension spring. The blocking piece can eject the seeds into the seed collection chamber, and can also prevent other debris from falling into the seed collection chamber. The blocking piece is triangular so that the blocking piece has less obstruction on the seeds, which is more conducive to collecting the seeds.

[0020] Furthermore, the distance between the wire mesh and the inner wall of the cavity is 1-3 cm, which is more conducive to collecting seeds.

[0021] Furthermore, a rubber pad is provided at the middle and lower part of the inner side of the annular plate, and the turntable is connected to the inner side of the annular plate by sliding up and down and rotating through the rubber pad. The rubber pad facilitates the arrangement of the turntable. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The clamping unit 30 includes a bottom block 31 and two clamping claws 35 arranged perpendicular to the shaft 21. The bottom block 31 is fixed on the shaft 21. A rectangular frame 32 is provided in the middle of the bottom block 31, and a sliding cavity 33 is provided inside the bottom block 31.

In this embodiment, a rubber pad 66 is provided at the middle and lower parts of the inner side of the annular plate 60, and the rotating disk 70 is slidably connected and rotatably connected to the inner side of the annular plate 60 through the rubber pad 66. The turntable 70 is provided with a leakage hole 71 smaller than the seed diameter, the lower end of the annular plate 60 is connected to the pipe 52, and the lower part of the pipe 52 is detachably connected to the filter tube 53; the lower part of the annular plate 60 is provided with a plurality of through holes 75 connected to the seed collecting chamber 43; a magnetic ring 73 is provided at the edge of the upper end of the turntable 70, and an electromagnet 64 is provided in the middle of the annular plate 60, which is attracted to the magnetic ring 73 when power is turned on; a key hole 72 is provided at the center of the turntable 70, and a short rod 24 is rotatably connected to the key hole 72 at the lower end of the key rod 23, and a key block 25 is provided at the lower end of the short rod 24, which extends into the key hole 72 and engages with it, and the length of the short rod 24 is equal to the vertical distance between the key rod 23 and the through hole 75.

[0030] When the bean husk plants are harvested after maturity, the blocking door 14 can be opened, a handful of legumes can be placed upside down in the housing 11 of the device, and the cut portion of the legumes can be clamped using the clamping unit 30. When the clamping unit 30 is used to clamp the legumes, the slider 37 is pulled downward to transfer the air in the slide cavity 33 so that the two slide bars 34 move into the slide cavity 33, and the ends of the two slide bars 34 away from the slide cavity 33 move away from each other, so that the two clamping claws 35 are separated; the legumes are placed between the two clamping claws 35, and the downward pull on the slider 37 is released. Under the elastic force of the elastic member 36, the slider 37 moves upward, and the air in the slide cavity 33 is transferred so that the two slide bars 34 extend out of the slide cavity 33, and the ends of the two slide bars 34 away from the slide cavity 33 move toward each other, so that the two clamping claws 35 move toward each other to grab the legumes.

[0031] After all the legumes are clamped on the clamping units 30, the baffle 14 is closed. The electric heating tube 51, the electric heating wire 41 and the electromagnet 64 are energized, and the exhaust fan is used to extract air at the filter tube 53. The air will enter the cavity 12 through the air inlet pipe 50 and be extracted through the pipe 52 and the filter tube 53. The air will be heated by the electric heating tube 51 before entering the cavity 12, and become hot air to enter the inner cavity. The electric heating wire 41 can heat the legumes in the cavity 12; the hot air entering the cavity 12 will be discharged through the pipe 52. During the discharge of the hot air through the pipe 52, small debris will be discharged through the leak hole 71 of the turntable 70, and the filter tube 53 will filter the discharged hot air.

[0032] In the above process, the hot air will dry the legumes, and the roots, stems, leaves and pods of the legumes will quickly draw away moisture in the flow of hot air. The pods will shrink after losing water and drying, but the water content of the seeds themselves is not high. Since they lose less water during the drying process when wrapped in the pods, their volume will not shrink too much; during the process of pod loss of water and shrinkage, the seeds will squeeze the pods to make them burst and pop out of the pods. After the seeds pop out, if they do not pop out in a vertical direction, they will be ejected onto the wire mesh 40 and enter the seed collection chamber 43 through the baffle 42. Some seeds will fall onto the rotating disk 70. Since the leakage hole 71 is smaller than the diameter of the seeds, the seeds will not flow with the hot air through the leakage hole 71 during the flow of hot air; when the electromagnet 64 is energized, it will adsorb the magnetic ring 73, so that the rotating disk 70 moves up in the annular plate 60, and the surroundings of the rotating disk 70 will not be aligned with the position where the through hole 75 is provided at the lower part of the annular plate 60, and at this time, the seeds will not enter the seed collection chamber 43 through the through hole 75.

[0033] After most of the moisture in the roots, stems, leaves and pods of the legumes is removed, the clamping unit 30 is controlled to release the clamping of the legumes, and the legumes will fall onto the turntable 70. During the flow of hot air, the impeller 22 will rotate under the action of the hot air, thereby rotating the shaft 21. The rotation of the shaft 21 will drive the short rod 24 and the key rod 23 to rotate, thereby rotating the rotating rod 62. During the rotation of the rotating rod 62, the two ends of the rotating rod 62 slide in the annular groove 61, so that the rotating rod 62 always keeps horizontal rotation. Since the short rod 24 is rotatably connected to the key hole 72, the length of the short rod 24 is equal to the vertical distance between the key rod 23 and the through hole 75. At this time, the short rod 24 is aligned with the key hole 72, so that the turntable 70 does not rotate. A crushing wheel is arranged on the outside of the rotating rod 62, and the crushing wheel will rotate horizontally with the rotating rod 62, so that the crushing wheel crushes the dried legumes on the turntable 70, and the plant debris produced by crushing will be taken away by the hot air through the leakage hole 71; after this process continues for a period of time, the roots, stems, leaves and pods of the legumes are basically crushed and discharged with the hot air.

[0034] At this time, the electromagnet 64 is powered off, and the rotating disk 70 will move downward under its own gravity. The seeds that have not leaked out through the leak hole 71 and are carried away by the hot air will enter the seed collecting chamber 43 through the through hole 75, and the individual seeds can be collected through the collecting tube 44. At the same time, after the rotating disk 70 moves downward, the through hole 75 will be located around the upper end of the rotating disk 70, and the key hole 72 will be engaged with the key block 25. Under the driving action of the shaft 21, the key block 25 rotates accordingly, thereby driving the rotating disk 70 to rotate; so that the seeds perform centrifugal motion on the rotating disk 70, which is more conducive to the seeds being thrown to the edge under the centrifugal force and entering the seed collecting chamber 43 through the through hole 75. Since the power of hot air flow comes from the filter tube 53, the continuous use of the exhaust fan will cause the shaft 21 to rotate continuously, and the pipe 52 is connected to the lower end of the annular plate 60, and the hot air is mainly sucked out through the pipe 52, thereby preventing the hot air from entering the seed collection chamber 43, so that the dust and debris of the legumes enter the seed collection chamber 43 with the seeds and contaminate the collected seeds. Some roots, stems, leaves and pods of legumes that cannot be crushed can be taken out by turning off the exhaust fan and opening the baffle 14 after all the seeds on the rotating disk 70 enter the seed collection chamber, and the next legume seed collection operation is carried out.

[0035] The above are only embodiments of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
