Description

Technical Field

[0001] The present invention relates to seed cultivation technology, and specifically to a new type of agricultural breeding equipment. Background Art

[0002] In agricultural production, it is often necessary to place agricultural seedlings in a breeding machine for cultivation. The breeding machine can automatically or manually perform operations such as watering, fertilizing, and providing sunlight to the seeds and seedlings in the breeding box. As a carrier for carrying seedlings, soil, water, fertilizer, etc., the breeding box needs to be stably suspended in the breeding machine and move its position as the equipment rotates. The convenience of its installation and the stability of its suspension are crucial for breeding efficiency and seedling growth.

[0003] The deficiencies of the prior art are that during the process of driving the breeding box to rotate, the breeding equipment lacks an effective limiting structure, which may cause the two groups of movable rods to flip simultaneously, resulting in the breeding box falling off due to unstable suspension. In addition, the connection method between the traditional movable rod and the fixed rod may have problems of inconvenient operation, and it is difficult to ensure that the breeding box always remains vertical during rotation, affecting the safety and reliability of seedling cultivation. Summary of the Invention

[0004] The purpose of the present invention is to provide a new type of agricultural breeding equipment to solve the above deficiencies in the prior art.

Symmetrical convex rings are provided on both sides of the surface of the central column, and the size of the convex ring is larger than that of the central column and protrudes outward and closely adheres to the inner side wall of the rotating sleeve, enabling the movable rod to rotate around the I-shaped column as the center.

[0011] As a further description of the above technical solution: The installation mechanism further includes a contact rod movably inserted in the middle of the rotating sleeve. One end of the contact rod is in contact connection with the surface of the I-shaped column, and the other end of the contact rod is movably inserted into both ends of a cavity opened in the central position of the load-bearing rod and connected to a movable column. The end face of the movable column connecting the contact rod is connected to the inner side walls of both ends of the cavity through a return spring. Two sides of the other end face of the movable column are slidably in contact with contact balls. The contact balls are fixedly installed at both ends of a lever.

The movable grooves are symmetrically opened on both sides of the middle part of the cavity.

[0012] As a further description of the above technical solution: Symmetrical rotating grooves with an isosceles trapezoid cross-section are opened on both sides inside the partition plate. The connection part of the two groups of rotating grooves is the short side of the isosceles trapezoid and is provided with a torsion spring shaft.

[0013] As a further description of the above technical solution: The surface of the movable rod is recessed inward and is smooth for sliding connection with the hanging ring.

[0014] As a further description of the above technical solution: The bottom of the movable end of the movable rod is recessed inward, and at the same time, the top of the end face of the connection end of the fixed rod and the movable rod is recessed inward, forming a snap connection between the movable end of the movable rod and the end face of the fixed rod.

[0018] In the above technical solution, a novel agricultural breeding device provided by the present invention has the following beneficial effects:

[0019] 1. Prevent the breeding box from falling off: The installation mechanism restricts the two movable rods from flipping simultaneously, and combines the downward pressure of the breeding box and the mutual limitation of the movable rods to ensure that the breeding box is stably suspended during the rotation of the turntable and avoid falling off.

[0020] 2. Easy to install and disassemble: The movable rod and the fixed rod are connected by snap-on connection, and the hanging ring can realize the quick installation and disassembly of the breeding box by squeezing the movable rod, which is easy to operate.

[0021] 3.

DETAILED DESCRIPTION

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] See also Figures 1-9 The embodiment of the present invention provides a new agricultural breeding equipment technical solution: comprising: a breeding machine 1, and also comprising:

[0038] Two groups of turntables 3 are rotatably mounted on both sides of the breeding machine 1 and connected to a motor 10 to achieve synchronous rotation of the two groups of turntables 3;

[0039] The fixed rod 6, the movable rod 7 and the load-bearing rod 4 are arranged between the two groups of rotating disks 3 to suspend the breeding box 5;

[0040] The installation mechanism is arranged at the connection between the two ends of the load-bearing rod 4 and the movable rod 7. When one group of movable rods 7 rotates, the other group of movable rods 7 is restricted from rotating, so that only one group of the two groups of movable rods 7 can be flipped and they cannot be flipped at the same time. When the breeding box 5 moves with the rotation of the turntable 3, the opening direction of the movable rod 7 is downward and is subjected to the downward pressure of the breeding box 5, and the two groups of movable rods 7 are limited to each other to prevent the breeding box 5 from falling off.

[0041] In another embodiment provided by the present invention, preferably, one end of the movable rod 7 connected with the fixed rod 6 by a snap-fit is the movable end, the end of the movable rod 7 connected with the load-bearing rod 4 is the rotating end, and the two ends of the load-bearing rod 4 are respectively connected to the rotating end of the movable rod 7, and multiple groups of fixed rods 6 are fixedly connected all around the inner side of the two groups of turntables 3.

[0042] In another embodiment provided by the present invention, the installation mechanism includes an I-shaped column 9 fixedly connected to the rotating end of the movable rod 7 through a connecting plate, and the transverse column connected to the middle of the I-shaped column 9 is a center column. The center column of the I-shaped column 9 is rotatably clamped in the rotating sleeve 11, and symmetrical convex rings 13 are arranged on both sides of the surface of the center column of the I-shaped column 9. The size of the convex ring 13 is larger than the size of the center column of the I-shaped column 9 and protrudes outward and is tightly attached to the inner wall of the rotating sleeve 11, so that the movable rod 7 rotates with the I-shaped column 9 as the center.

[0043] In another embodiment provided by the present invention, the installation mechanism also includes a resistance rod 12 movably inserted in the middle part of the rotating sleeve 11, one end of the resistance rod 12 is abutted against the surface of the I-shaped column 9, and the other end of the resistance rod 12 is movably inserted in the two ends of the cavity 22 opened at the center position of the load-bearing rod 4 and connected to the movable column 15. The movable column 15 is connected to the end surface of the resistance rod 12 and is connected to the inner side walls of the two ends of the cavity 22 through a reset spring 23. Resistance balls 20 are connected on both sides of the other end surface of the movable column 15 in sliding contact. The resistance balls 20 are fixedly installed at both ends of the lever 18. The lever 18 penetrates the partition 17 and is rotatably installed in the movable groove 19 through the torsion spring shaft 16. The movable groove 19 is symmetrically opened on both side walls of the middle part of the cavity 22.

[0044] In another embodiment of the present invention, rotation grooves 21 with isosceles trapezoidal cross sections are symmetrically opened on both sides of the partition 17, and the connecting point of the two groups of rotation grooves 21 is the short side of the isosceles trapezoid and is equipped with a torsion spring shaft 16.

[0045] In another embodiment provided by the present invention, the surface of the movable rod 7 is concave inward and smooth and is slidably connected to the hanging ring 8 .

[0046] In another embodiment provided by the present invention, the bottom of the movable end of the movable rod 7 is recessed inward, and the top of the connecting end surface of the fixed rod 6 and the movable rod 7 is recessed inward, forming a snap-on connection between the movable end of the movable rod 7 and the end surface of the fixed rod 6.

[0047] In another embodiment provided by the present invention, a transparent cover 2 is slidably mounted on the surface of the breeding machine 1, which protects the inside of the breeding machine 1 and facilitates observation of seedling growth.

[0048] In another embodiment provided by the present invention, a motor 10 is provided at the connection between a set of rotating disks 3 and the inner wall of the breeding machine 1 to drive the rotating disks 3 to rotate.

[0049] In yet another embodiment provided by the present invention, preferably, a hanging ring 8 is movably sleeved on the surface of the movable rod 7 , and the hanging ring 8 is fixedly mounted on the surfaces of both ends of the breeding box 5 .

[0050] In agricultural production, it is necessary to place agricultural seedlings in the breeding machine 1 for cultivation. The breeding machine 1 can automatically water and fertilize the seeds and seedlings in the breeding box 5 and provide sunlight and other environments;

[0051] After powering on the breeding machine 1 and setting the durations of watering, fertilizing, and sunlight exposure according to the type of seeds to be cultivated, the breeding machine can automatically water, fertilize, and provide sunlight. This is prior art and will not be elaborated further. Alternatively, after manually opening the transparent cover 2 of the breeding machine 1, one can manually water, fertilize inside the breeding box 5, and turn off or on the sunlight lamp;

[0052] Take out the required breeding box 5. Lift the breeding box 5 and squeeze the hanging rings 8 provided at both ends of the surface of the breeding box 5 against the movable rods 7 one by one. The hanging rings 8 squeeze the movable rods 7 upward. During the process of the movable end of the movable rod 7 being squeezed upward, the movable end of the movable rod 7 is lifted upward and separated from the fixed rod 6. At this time, the I-shaped column 9 fixedly connected to the bottom end of the movable rod 7 through the connecting rod 14 will flip upward within the rotating sleeve 11. While the I-shaped column 9 is rotating, the convex ring 13 provided on the surface of the I-shaped column 9 will squeeze one end of the contact rod 12 movably inserted inside the rotating sleeve 11 due to outward expansion of its size, and squeeze the contact rod 12 into the rotating sleeve 11 and the load-bearing rod 4, so that the other end of the contact rod 12 slides the movable column 15 movably connected inside the cavity 22 opened in the middle of the load-bearing rod 4 towards the middle position of the cavity 22. Since only one-sided movement of the movable column 15 occurs, while the movable column 15 slides towards the middle position of the cavity 22, the movable column 15 squeezes the contact balls 20 provided on both sides of the cavity 22 due to its own size, and squeezes the contact balls 20 into the movable groove 19. While the contact balls 20 are being squeezed into the movable groove 19, the contact balls 20 connecting this end drive the lever 18 at this end to also rotate into the movable groove 19. Thus, under the action of the torsion spring rotating shaft 16 provided at the middle end of the lever 18, the other end of the lever 18 moves into the cavity 22 to ensure that the movable rod 7 at the rotating end can rotate upward to open, so as to realize inserting the hanging ring 8 outside the fixed rod 6. After the movable rod 7 is reset, after the contact rod 12 loses the contact of the convex ring 13, under the reset action of the reset spring 23 after being squeezed, the movable rod 7 drives the contact rod 12 to be inserted into the rotating sleeve 11 again to keep one end of the contact rod 12 always closely attached to the surface of the I-shaped column 9;

[0053] The maximum angle of upward flipping of the movable rod 7 is restricted by the port part of the rotating sleeve 11 on the connecting rod 14. When the movable rod 7 flips upward to the limit position, at this time, the port of the rotating sleeve 11 will touch the surface of the connecting rod 14, thereby restricting the rotation angle of the movable rod 7;

[0054] After hanging the hanging ring 8 at one end of the breeding box 5 on the fixed rod 6, at this time, the movable rod 7 loses the resistance of the hanging ring 8. Under the action of gravity, the movable end of the movable rod 7 automatically resets downward. After connecting the movable end of the movable rod 7 to the end of the fixed rod 6, at this time, continue to resist the movable rod 7 at the other end with the hanging ring 8 at the other end of the breeding box 5, and hang it on the fixed rod 6 through the hanging ring 8, so as to install the breeding box 5. When the breeding box 5 is installed, the hanging rings 8 at both ends of the breeding box 5 are just on the surfaces of the two groups of movable rods 7;

[0055] At this time, necessary items for breeding such as soil, water, fertilizer and seedlings can be filled in the breeding box 5, and then the breeding box 5 can be placed in the breeding machine 1 for breeding use;

[0056] After installing multiple groups of breeding boxes 5 and adding seedlings for cultivation, close the transparent cover 2 and cultivate the seedlings in the breeding machine 1. And during the cultivation process or when installing the breeding box 5, it is necessary to adjust the position of the load-bearing rod 4 according to the position of the installed breeding box 5. At this time, start the turntable 3 to rotate through the motor 10;

[0057] The fixed rod 6 is fixedly connected to the inner sides of the two turntables 3. Therefore, when the turntable 3 rotates, the connection position between the fixed rod 6 and the movable rod 7 will change in angle with the rotation of the turntable 3. The connection position between the fixed rod 6 and the movable rod 7 at the top of the turntable 3 can turn the movable end of the movable rod 7 upward, and the connection position between the fixed rod 6 and the movable rod 7 at the bottom of the turntable 3 can turn the movable rod 7 downward. When installing the breeding box 5 with the hanging ring 8 hung on the surfaces of the fixed rod 6 and the movable rod 7, when the fixed rod 6 and the movable rod 7 rotate to the bottom, at this time, the hanging ring 8 will pull down the movable rod 7 due to the gravity of the breeding box 5. At this time, since the two hanging rings 8 press and turn the two groups of movable rods 7 downward at the same time, and when the two groups of movable rods 7 turn at the same time, the rotating end of the movable rod 7 will resist the resisting rod 12, and the resisting rod 12 drives the two movable columns 15 in the cavity 22 to resist the resisting balls 20 at both ends of the lever 18 at the same time. When the resisting balls 20 at both ends of the lever 18 are resisted at the same time, the lever 18 is restricted by the size of the middle partition 17 and cannot be squeezed into the movable groove 19, resulting in the resisting balls 20 at both ends of the lever 18 producing a resisting effect on the movable column 15, and the movable column 15 cannot be inserted into the cavity 22 due to the resistance of the resisting ball 20. At the same time, the immobility of the movable column 15 acts on the connection between the resisting rod 12 and the I-shaped column 9, resisting the I-shaped column 9, resulting in the I-shaped column 9 not being able to rotate, thereby preventing the two groups of movable rods 7 from turning downward either, so as to ensure that the breeding box 5 will not fall off from the movable rod 7 when the breeding box 5 rotates with the turntable 3, and at the same time, it will not affect the disassembly and installation of the breeding box 5.

[0058] It should be noted that:

[0059] A torsion spring shaft 16 with a rotating effect is installed in the middle of the partition 17. At the same time, a rotating groove 21 with an isosceles trapezoidal cross section is opened on both sides of the torsion spring shaft 16, and the short side of the isosceles trapezoid is attached to the torsion spring shaft 16, and the long side of the isosceles trapezoid is attached to the openings at both ends of the partition 17. The lever 18 rotatably inserted in the partition 17 can only rotate the two ends up and down, but the lever 18 cannot slide up and down synchronously as a whole;

[0060] The edges of the convex ring 13 arranged on the upper and lower sides of the column body in the middle of the I-shaped column 9 are located on both sides of the connection between the interference rod 12 and the main body in the middle of the I-shaped column 9, and the interference rod 12 is closely attached to the surface of the I-shaped column 9. When the I-shaped column 9 rotates, the interference rod 12 can be slid from the surface of the I-shaped column 9 to the surface of the convex ring 13 to achieve interference with the interference rod 12;

[0061] The bottom of the movable end of the movable rod 7 is concave inwards, and the top of the end surface of the connecting end of the fixed rod 6 and the movable rod 7 is concave inwards. When the movable rod 7 and the fixed rod 6 are located at the highest point of the turntable 3, the movable end of the movable rod 7 can be restricted by the end surfaces of the fixed rod 6 and cannot be turned downwards. The movable rod 7 can only be turned upwards to open;

[0062] The surface of the movable rod 7 is smooth and concave inwardly so that the hanging ring 8 can be stuck in the concave position. As the turntable 3 rotates, the hanging ring 8 can only slide on the surface of the movable rod 7. The movable rod 7 will not hinder the inner side of the hanging ring 8, causing the breeding box 5 to flip over when the turntable 3 rotates and cannot always maintain a vertical downward position.

[0063] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
