Description

Technical Field

[0001] The invention belongs to the technical field of alfalfa breeding, and in particular relates to a cutting breeding device and a breeding method for alfalfa cultivation. Background Art

[0002] Alfalfa is rich in protein, mineral elements and carbohydrates, among which crude protein is the highest. All crude proteins can be digested, and the amino acid composition is similar to that of whey powder. Therefore, alfalfa is often used to make high-quality fiber feed. Alfalfa cutting propagation has the advantage of high yield, which is of great significance for maintaining the quality of alfalfa, accelerating reproduction and cultivating good varieties.

[0003] In the prior art, during the cultivation of alfalfa, artificial irrigation is generally used to realize the irrigation and cultivation of alfalfa on the cultivation rack. The artificial irrigation method cannot accurately control the amount of watering. When the amount of watering is insufficient, it is easy to cause the root system of alfalfa cuttings to be unable to absorb sufficient water, which is not conducive to the growth of alfalfa cuttings. When the amount of watering is too much, it is easy to cause the root system of alfalfa cuttings to be unable to absorb sufficient air, which is also not conducive to the growth of alfalfa cuttings. To this end, we provide a cutting breeding device and breeding method for alfalfa cultivation to solve the above problems. Summary of the invention

[0014] The present invention has the following beneficial effects: 1. The present invention intermittently controls the water flow transfer plate to rotate counterclockwise by 180°, so that the water flow in the upper arc-shaped transfer cavity flows along the second discharge port and the first discharge port into the irrigation cavity composed of the cavity bottom plate and the two inner extension support seats. At the same time, the water in the water storage tank flows along the first water inlet and the second discharge port to fill the arc-shaped transfer cavity below. Such a cyclic operation can transport a certain amount of water in the water storage tank to the irrigation cavity until the porous supporting frame moves downward to abut against the bottom of the irrigation cavity. At this time, the first fixed frame and the porous supporting frame are in the lowest position, and the screw rod adapter seat moves up to the top of the reciprocating spiral groove corresponding to the reciprocating screw rod. When the porous supporting frame enters the irrigation cavity, the roots of alfalfa cuttings at various positions in the cultivation soil can evenly absorb sufficient water, which can effectively avoid the problem of insufficient and uneven water absorption by the roots of alfalfa cuttings.

[0015] 2. In the present invention, after the roots of alfalfa cuttings absorb water for the time set by the controller, the controller controls the reciprocating screw to continue rotating, and under the action of the reciprocating screw, each screw adapter seat moves downward synchronously, and the second rack that moves downward synchronously with the screw adapter seat drives the first gear to rotate clockwise, and under the action of the first gear, drives the first rack to move upward, thereby causing the first fixed frame to slide upward along the limiting slide until the first fixed frame rests against the top of the limiting slide again. At this time, the porous supporting frame returns to the initial position, and the screw adapter seat at the initial position is not at the bottom of the corresponding reciprocating spiral groove. Subsequently, the residual water absorbed by the cultivation soil in the porous supporting frame can drip into the irrigation chamber below through the water filter holes, thereby effectively avoiding the root hypoxia problem caused by excessive residual water in the cultivation soil.

[0016] 3. When the components in the cutting breeding unit are controlled to complete the reset and return to the initial position, the lower pressure plate that moves downward pushes the lifting and toggle plate to make it rotate counterclockwise, and the lifting and toggle plate that rotates counterclockwise pushes the force-bearing moving frame upward, and the cavity bottom plate moves upward under the action of the force-bearing moving frame. When the top of the cavity bottom plate is just flush with the top surfaces of the overflow box and the mud collecting box, the left side wall of the lifting and toggle plate just fits on one side of the lower pressure plate, and the third rack just contacts the second gear. The lifting and toggle plate no longer moves during the lower pressure plate's continued downward movement. The second gear is driven to rotate by the third rack which moves downward, and the cavity cleaning push plate moves toward the baffle plate under the action of the cavity cleaning screw. The soil attached to the cavity bottom plate is pushed toward the mud collecting box by the horizontally moving cavity cleaning push plate. When the push-off part contacts the baffle plate, the elastic element is compressed until the screw adapter seats move synchronously downward to the bottom of the corresponding reciprocating spiral grooves. At this time, the soil attached to the cavity bottom plate is completely pushed into the mud collecting box.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] For specific embodiment 1, please refer to Figure 1-12 The present invention is a cutting breeding device for alfalfa cultivation, comprising a plurality of cutting breeding units 1 arranged in an upper and lower array; wherein the cutting breeding unit 1 comprises a water immersion control mechanism 2, a water flow transfer mechanism 3, a breeding bearing mechanism 4, a power control mechanism 5 and a cavity clearing control mechanism 6; the water immersion control mechanism 2 comprises a horizontally arranged water storage tank 201, both ends of the water storage tank 201 are fixedly installed with hollow guide plates 202 connected thereto, and two inner extension support seats 203 are symmetrically installed between the two hollow guide plates 202; the water flow transfer mechanism 3 is arranged one-to-one with the hollow guide plates 202, the water flow transfer mechanism 3 is rotatably installed inside the corresponding hollow guide plates 202 and the two are arranged coaxially, and the water flow transfer mechanism 3 comprises an arc-shaped transfer cavity 301, through which the water flow in the water storage tank 201 is transported to between the two inner extension support seats 203.

[0035] The breeding support mechanism 4 is fixedly installed between the two hollow guide plates 202, and the breeding support mechanism 4 includes a porous support frame 401 for cutting breeding. The porous support frame 401 is located directly above the two inner extension support seats 203, and the first racks 402 that move up and down synchronously are installed on opposite sides of the porous support frame 401, and the water flow transfer mechanism 3 is meshed with the corresponding first rack 402; the power control mechanism 5 is symmetrically installed on both sides of the water immersion control mechanism 2, and the power control mechanism 5 is meshed with the corresponding water flow transfer mechanism 3; the cavity clearing control mechanism 6 is arranged on one side of the water immersion control mechanism 2, and the cavity clearing control mechanism 6 is fixedly installed between the two power control mechanisms 5, and the cavity clearing control mechanism 6 includes a cavity bottom plate 601, and the cavity bottom plate 601 is fitted between the two inner extension support seats 203.

[0036] In this embodiment of the present invention, a mounting seat 204 is fixedly provided on one side of the hollow guide plate 202, and a guide seat 205 is fixedly provided on the inner side of the mounting seat 204. The cutting breeding unit 1 is fixedly installed on the external frame through the mounting seat 204. A first water inlet and a first drain port 206 connected to its inner cavity are provided on the surface of the hollow guide plate 202. The first water inlet is arranged on the inner side of the water tank 201, and the first drain port 206 is arranged between the two inner extension support seats 203. A water supply pipe 207 connected to the water tank 201 is fixedly installed on one side of the water tank 201. The water supply pipe 207 can be made of transparent material to observe the water level changes in the water tank 201, and the water level in the water tank 201 is judged according to the liquid level in the water supply pipe 207.

[0037] In this embodiment of the present invention, the water flow transfer mechanism 3 also includes a water flow transfer plate 302 with a clearance fit inside the corresponding hollow guide plate 202, and the arc-shaped transfer cavity 301 is symmetrically opened on the side surface of the water flow transfer plate 302. A connecting shaft fixed on one side of the water flow transfer plate 302 is rotatably set on the corresponding hollow guide plate 202, and a first gear 303 is fixedly installed on the end of the connecting shaft. A second water inlet 304 and a second drain port 305 are symmetrically opened on one side of the water flow transfer plate 302 away from the first gear 303. The arc-shaped transfer cavity 301 is connected to the corresponding second water inlet 304 and the second discharge port 305. In the initial state, the first water inlet is aligned with a second water inlet 304. At this time, the water in the water tank 201 flows by gravity through the first water inlet and the second water inlet 304 into the corresponding arc-shaped transfer cavity 301 (because the first water inlet is located higher than the corresponding arc-shaped transfer cavity 301, that is, the arc-shaped transfer cavity 301 is located below, it can ensure that the water flows by gravity into the corresponding arc-shaped transfer cavity 301).

[0038] In this embodiment of the present invention, the breeding support mechanism 4 also includes a support ring 403 corresponding to the hollow guide plate 202, the support ring 403 is fixedly installed on the side surface of the corresponding hollow guide plate 202, and two vertically arranged guide tubes 404 are fixedly arranged on the side surface of the support ring 403. A vertical lifting seat 405 (such as Fig. 9 As shown in the figure, a guide rod 406 is fixedly arranged at the bottom of the ear seat fixed on the surface of the vertical lifting seat 405, and the guide rod 406 is slidably fitted in the corresponding guide tube 404. The porous bearing frame 401 and the first racks 402 on both sides thereof are connected through a first fixing frame 407, and the first fixing frame 407 is slidably fitted in the limiting slideway 408 on the corresponding vertical lifting seat 405. Fig. 9All structures are in the initial position. At this time, when the first rack 402 is controlled to move upward, the vertical lifting seat 405 can be pushed to move upward through the first fixed frame 407, thereby realizing the lifting of the porous supporting frame 401. During this process, the guide rod 406 slides upward along the guide tube 404. When the first rack 402 is controlled to move downward from the initial position, since the bottom of the vertical lifting seat 405 is against the top of the support ring 403, the downward-moving first rack 402 brings the first fixed frame 407 downward synchronously, thereby realizing the descent of the porous supporting frame 401. During this process, the guide rod 406 and the guide tube 404 do not slide relative to each other.

[0039] In this embodiment of the present invention, the power control mechanism 5 includes a power control frame 501 slidably arranged inside the corresponding guide seat 205, the power control mechanism 5 includes a second rack 502, a second rack 502 is fixedly arranged on one side of the power control frame 501, the first gear 303 and the first rack 402 and the second rack 502 on both sides thereof are meshed with each other, and a screw adapter seat 503 is fixedly arranged at the bottom of the power control frame 501, and the screw adapter seat 503 is sleeved on the reciprocating screw 7 and the two are in transmission cooperation, such as Figure 1 As shown, each cutting breeding unit 1 is sleeved on two reciprocating screws 7, and a transmission wheel is fixed on each reciprocating screw 7. The transmission wheels between the two reciprocating screws 7 are connected by a transmission belt. One of the reciprocating screws 7 is driven by a motor (not shown in the figure), and a reciprocating spiral groove (similar to the spiral structure on a conventional reciprocating screw) corresponding to the screw adapter seat 503 is provided on the reciprocating screw 7. The rotation of the reciprocating screw 7 is controlled by the motor, so that the synchronous up and down movement of the power control mechanism 5 on each cutting breeding unit 1 can be realized.

[0040] In the initial state, the bottom of the vertical lifting seat 405 is against the top of the support ring 403, the first fixing frame 407 is fitted on the top of the limiting slide 408, and the porous bearing frame 401 is located directly above the cavity bottom plate 601. The alfalfa cuttings are inserted into the cultivation soil in the porous bearing frame 401. At this time, the first rack 402 is engaged and locked by the first gear 303 to ensure the stability of the position of the porous bearing frame 401. The cavity bottom plate 601 is fitted on the bottom of the two inner extension brackets 203, and the first water inlet is aligned with a second water inlet 304. (the second water inlet 304 at the bottom), the first discharge port 206 is aligned with the second discharge port 305 at the top, and the water in the water storage tank 201 flows by gravity through the first water inlet and the second water inlet 304 into the corresponding arc-shaped transfer cavity 301 to fill the arc-shaped transfer cavity 301 (the arc-shaped transfer cavity 301 at the bottom), and the controller controls the left and right reciprocating screws 7 to rotate synchronously according to the set irrigation program, so that each power control mechanism 5 moves upward synchronously, and in this process, the first gear 303 is driven to rotate counterclockwise (such as the second gear rack 502 that moves upward) through the second gear rack 502 that moves upward. Figure 4 As shown), the first rack 402 is driven downward by the action of the first gear 303, and then the porous supporting frame 401 is driven to move downward synchronously while controlling the water flow transfer disc 302 to rotate counterclockwise. Whenever the water flow transfer disc 302 rotates 180° counterclockwise, the porous supporting frame 401 moves down the same distance. At this time, the reciprocating screw rod 7 stops rotating for a period of time, so that the arc transfer chamber 301 filled with water rotates to the upper position (at this time, the second drain port 305 at the position of the arc transfer chamber 301 is aligned with the first drain port 206, and the second water inlet 304 at the position of the lower arc transfer chamber 301 is aligned with the first water inlet). While the water in the upper arc transfer chamber 301 flows along the second drain port 305 and the first drain port 206 to the irrigation chamber composed of the cavity bottom plate 601 and the two inner extension support seats 203, the water in the water storage tank 201 flows along the first water inlet and the second drain port 305 to fill the lower arc transfer chamber 301.

[0041] Subsequently, the controller continues to control the reciprocating screw rod 7 to rotate by the same amplitude and then pauses the reciprocating screw rod 7 again, so that the water transfer plate 302 continues to rotate 180° counterclockwise. At this time, the porous supporting frame 401 moves down by the same distance again, and the water in the upper arc-shaped transfer cavity 301 flows along the second discharge port 305 and the first discharge port 206 to the irrigation cavity composed of the cavity bottom plate 601 and the two inner extension support seats 203. At the same time, the water in the water storage tank 201 flows along the first water inlet and the second discharge port 305 to fill the arc-shaped transfer cavity 301 below. This cycle can be repeated. A certain amount of water in the water tank 201 is transported to the irrigation chamber until the porous supporting frame 401 moves downward to rest against the bottom of the irrigation chamber (the rotation of the reciprocating screw 7 is paused). At this time, the first fixed frame 407 and the porous supporting frame 401 are at the lowest position, and the screw adapter 503 moves up to the top of the corresponding reciprocating spiral groove on the reciprocating screw 7. When the porous supporting frame 401 enters the irrigation chamber, the roots of alfalfa cuttings at various positions in the cultivation soil can evenly absorb sufficient water, which can effectively avoid the problem of insufficient and uneven water absorption by the roots of alfalfa cuttings.

[0042] After the alfalfa cuttings roots absorb water for the time set by the controller, the controller controls the reciprocating screw 7 to continue rotating, and under the action of the reciprocating screw 7, each screw adapter seat 503 moves downward synchronously, and the second rack 502 that moves downward synchronously with the screw adapter seat 503 drives the first gear 303 to rotate clockwise, and under the action of the first gear 303, the first rack 402 is driven to move upward, so that the first fixed frame 407 slides upward along the limiting slide 408 until the first fixed frame 407 is back against the top of the limiting slide 408. At this time, the porous supporting frame 401 returns to the initial position, and the screw adapter seat 503 at the initial position is not at the bottom position of the corresponding reciprocating spiral groove. Subsequently, the residual moisture absorbed by the cultivation soil in the porous supporting frame 401 can drip into the irrigation chamber below through the water filter holes, thereby effectively avoiding the root hypoxia problem caused by excessive residual moisture in the cultivation soil.

[0043] Specific embodiment 2, on the basis of specific embodiment 1, sealing plates 602 that are fitted with the hollow guide plate 202 are fixedly arranged on opposite sides of the cavity bottom plate 601, and a third drain port 603 corresponding to the first drain port 206 is opened on the surface of the sealing plate 602. The third drain port 603 in the initial state is connected to the first drain port 206. When the water flow transfer plate 302 is controlled to rotate 180° counterclockwise so that the second drain port 305 and the first drain port 206 are aligned and connected, the water flow in the upper arc-shaped transfer cavity 301 passes through the second drain port 305, the first drain port 206 and the third drain port 603 in turn and flows into the pouring cavity composed of the cavity bottom plate 601 and the two inner extension support seats 203. The bottom of the cavity bottom plate 601 is fixedly provided with A force-bearing movable frame 604 is arranged, and a limiting column 605 and a supporting shaft 606 are respectively arranged on one side of the water tank 201 close to the force-bearing movable frame 604. The limiting column 605 is fixedly connected to the water tank 201, and the supporting shaft 606 is rotatably connected to the water tank 201.

[0046] When the various components in the cutting breeding unit 1 are controlled to complete the reset and return to the initial position (that is, the bottom of the vertical lifting seat 405 is against the top of the support ring 403, the first fixing frame 407 is attached to the top of the limiting slide 408, the porous bearing frame 401 is located directly above the cavity bottom plate 601, the cavity bottom plate 601 is attached to the bottom of the two inner extension support seats 203, the first water inlet is aligned with a second water inlet 304, the first drain port 206 is aligned with the upper second drain port 305, and the bottom of the lower pressure plate 611 is just attached to the cavity bottom plate 601.

During this process, the lower pressure plate 611 moves downward to push the lifting and toggling plate 607 to make it rotate counterclockwise (such as Fig.11 As shown in the figure, the lifting and lowering toggle plate 607 rotating counterclockwise pushes the force-bearing movable frame 604 upward, and the cavity bottom plate 601 moves upward under the action of the force-bearing movable frame 604, and the blocking plate 602 moves upward synchronously with the cavity bottom plate 601, so that the third drain port 603 and the second drain port 305 are misaligned, and the rotating water flow transfer plate 302 no longer transports water to the irrigation chamber, and the second rack 502 that moves downward synchronously with the screw adapter seat 503 drives the first gear 303 to rotate clockwise The first rack 402 is driven to move upwards under the action of the first gear 303, and the vertical lifting seat 405 is pushed upwards under the action of the first fixing frame 407, so that the porous bearing frame 401 continues to move upwards for a distance.

9. The breeding method of a cutting breeding device for alfalfa cultivation as claimed in claim 8, characterized in that: The steps include: S01. The controller controls the left and right reciprocating screws (7) to rotate synchronously according to the set irrigation program, so that each power control mechanism (5) moves upward synchronously. In this process, the second rack (502) that moves upward drives the first gear (303) to rotate counterclockwise, and the first rack (402) is driven to move downward under the action of the first gear (303), thereby controlling the water flow transfer plate (302) to rotate counterclockwise and driving the porous bearing frame (401) to move downward synchronously. Whenever the water flow transfer plate (302) rotates 180° counterclockwise, At the same time, the porous bearing frame (401) moves downward by the same distance, and the reciprocating screw rod (7) stops rotating for a period of time, so that the arc-shaped transfer chamber (301) filled with water rotates to the upper position, and the water in the upper arc-shaped transfer chamber (301) flows along the second discharge port (305) and the first discharge port (206) into the irrigation chamber composed of the chamber bottom plate (601) and the two inner extension support seats (203), while the water in the water storage tank (201) flows along the first water inlet and the second discharge port (305) to fill the lower arc-shaped transfer chamber (301); S02, the controller then continues to control the reciprocating screw (7) to rotate by the same amplitude and then stops the reciprocating screw (7) again, so that the water flow transfer plate (302) continues to rotate 180° counterclockwise. At this time, the porous support frame (401) moves down by the same distance again. The water in the upper arc-shaped transfer cavity (301) flows along the second discharge port (305) and the first discharge port (206) into the irrigation cavity formed by the cavity bottom plate (601) and the two inner extension support seats (203). At the same time, the water storage tank ( The water in the water storage tank (201) flows along the first water inlet and the second discharge port (305) to fill the arc-shaped transfer chamber (301) below. In this way, a certain amount of water in the water storage tank (201) can be transported to the irrigation chamber by a cyclic operation until the porous bearing frame (401) moves downward to abut against the bottom of the irrigation chamber. At this time, the first fixing frame (407) and the porous bearing frame (401) are at the lowest position, and the screw adapter seat (503) moves upward to the top of the corresponding reciprocating spiral groove on the reciprocating screw (7); S03. After the alfalfa cutting root system absorbs water for a time set by the controller, the controller controls the reciprocating screw (7) to continue rotating. Under the action of the reciprocating screw (7), each screw adapter seat (503) moves downward synchronously. The second rack (502) that moves downward synchronously with the screw adapter seat (503) drives the first gear (303) to rotate clockwise. Under the action of the first gear (303), the first rack (402) moves upward, thereby causing the first fixed frame (407) to slide upward along the limiting slide (408) until the first fixed frame (407) is again against the top of the limiting slide (408). At this time, the porous bearing frame (401) returns to the initial position, and the screw adapter seat (503) at the initial position is not at the bottom of the corresponding reciprocating spiral groove. Subsequently, the residual water absorbed by the cultivation soil in the porous bearing frame (401) can drip into the irrigation chamber below through the water filter hole; S04. When the components in the cutting breeding unit (1) are controlled to complete the reset and return to the initial position, the controller pauses the rotation of the reciprocating screw (7). After a period of time, the controller controls the reciprocating screw (7) to rotate slightly again, so that each screw adapter (503) moves down to the bottom of the corresponding reciprocating spiral groove synchronously. During this process, the lower pressure plate (611) moves downward to push the lifting and lowering toggle plate (607) to make it rotate counterclockwise. The lifting and lowering toggle plate (607) that rotates counterclockwise pushes the force-bearing movable frame (604) upward, and under the action of the force-bearing movable frame (604), the cavity bottom plate (601) moves upward. The sealing plate (602) moves upward synchronously with the cavity bottom plate (601), so that the third drain port (603) and the second drain port (305) are misaligned, and the rotating water transfer plate (302) no longer transports water into the irrigation chamber. The second rack (502) that moves downward synchronously with the screw adapter seat (503) drives the first gear (303) to rotate clockwise, and the first rack (402) is driven to continue to move upward under the action of the first gear (303). The vertical lifting seat (405) is pushed to move upward under the action of the first fixing frame (407), thereby causing the porous bearing frame (401) to continue to move upward for a distance; S05. When the top of the cavity bottom plate (601) is just flush with the top surfaces of the overflow box (208) and the mud collecting box (209), the left wall of the lifting and shifting plate (607) is just in contact with the side of the lower pressure plate (611), and at this time the third rack (610) just contacts the second gear (615). As the lower pressure plate (611) continues to move downward, the lifting and shifting plate (607) no longer rotates, thereby keeping the cavity bottom plate (601) in a position flush with the top surfaces of the overflow box (208) and the mud collecting box (209). The third rack (610) that moves downward drives the second gear (615). (615) rotates, and under the action of the cavity cleaning screw (614), the cavity cleaning push plate (616) moves toward the baffle plate (617), and the soil attached to the cavity bottom plate (601) is pushed toward the mud collecting box (209) by the horizontally moving cavity cleaning push plate (616). When the push-off member (618) contacts the baffle plate (617), the elastic element (619) is compressed until each screw adapter seat (503) moves down synchronously to the bottom of the corresponding reciprocating spiral groove, and at this time, the soil attached to the cavity bottom plate (601) is completely pushed into the mud collecting box (209); S06. Finally, the reciprocating screw rod (7) is controlled to rotate so that each power control mechanism (5) moves upward synchronously until each component in the cutting breeding unit (1) is reset to the initial position. In this way, the watering operation of the alfalfa cuttings in the porous supporting frame (401) can be realized in a timed manner according to the program set by the controller.
