Description

Technical Field

[0001] This utility model relates to the field of agricultural transplanter technology, specifically a single-opening inclined clamping seedling cup. Background Technology

[0002] In existing agricultural transplanters, traditional seedling cup designs mostly adopt a double-opening structure, whose opening and closing control mechanism is usually quite complex, resulting in a cumbersome overall mechanical structure and thus increasing manufacturing and maintenance costs. Furthermore, the double-opening design often requires more sophisticated drive devices and control systems, which inherently increases the complexity and cost of the equipment and is not conducive to large-scale production.

[0003] On the other hand, traditional seedling cups cannot effectively ensure that seedlings are in an ideal upward orientation when stored. Seedlings may be flipped or placed unstablely during transportation, causing them to bend or tip over during final transplanting, which seriously affects planting quality and survival rate.

[0004] In addition, existing seedling cups generally suffer from poor applicability and inconvenient disassembly and maintenance. Because different models of agricultural transplanters or robotic arms have different installation interfaces, traditional seedling cups have poor versatility, and the disassembly and assembly process is cumbersome when replacement or repair is needed, which brings considerable difficulties to maintenance.

[0005] Therefore, there is an urgent need for a seedling cup design that can simplify the structure, improve applicability, and effectively ensure the stable transfer of seedlings, so as to improve the working efficiency of agricultural transplanters, reduce production costs, and improve the quality of crop planting.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0035] Please refer to Figures 1-5 A single opening type inclined clamping type seedling cup is installed on an agricultural transplanting machine and comprises a seedling cup body 1 and a single opening door 2. The seedling cup body 1 is fixedly installed on a transmission component of the agricultural transplanting machine. The inner cavity of the seedling cup body 1 is designed as an upper wide and lower narrow structure. The top and bottom of the seedling cup body 1 are respectively provided with a seedling loading port 11 and a seedling unloading port 12. The bottom of the seedling cup body 1 is fixedly connected with a clamping plate 13 arranged at one side of the seedling unloading port 12.

[0036] The single opening door 2 is rotatably installed at the bottom of the seedling cup body 1. An elastic member 21 is assembled at the connection between the single opening door 2 and the seedling cup body 1. The elastic member 21 is used for matching and combining the clamping plate 13 and the single opening door 2 and blocking the seedling unloading port 12.

[0037] A horizontally arranged assembly pin shaft 22 is fixedly connected to the outer side wall of the single opening door 2. A driving member 23 is assembled on the assembly pin shaft 22. An acting member 3 is fixedly connected to the frame of the agricultural transplanting machine. When the driving member 23 runs to the position of the acting member 3 along with the transmission component, the driving member 23 and the single opening door 2 are pushed by the acting member 3 to perform a flipping movement and are in an open posture.

[0038] The transmission component can adopt a chain or belt type transmission device, and a plurality of groups of seedling cups 1 are uniformly arranged on the transmission component. The seedling cups 1 are driven by the transmission component to circulate and transfer between the seedling tray and the transplanting nozzle arranged on the machine. The seedlings in the seedling cups 1 are transferred from the seedling loading port 11 at the top of the seedling cups 1 to the seedling tray by the mechanical arm arranged on the seedling tray.

[0039] Due to the design of the inner cavity of the seedling cup 1 being wide at the top and narrow at the bottom, the seedlings falling into the seedling cup 1 can be stored in a vertical upward posture at the bottom of the seedling cup 1, and the seedlings are prevented from leaking out of the seedling unloading port 12 at the bottom of the seedling cup 1 during the transfer process by the cooperation of the single-door 2 and the clamping plate 13 in the closed posture.

[0040] The acting element 3 is arranged at the position of the circulating and rotating transplanting nozzle. When the seedling cup 1 loaded with seedlings is transported to the position by the transmission component, the acting element 3 interacts with the driving element 23 on the single-door 2, and during the continuous operation of the transmission component, the acting element 3 can apply a force to the driving element 23 to make the single-door 2 turn outward and be in an open posture. The seedlings stored in the seedling cup 1 can leak into the corresponding position of the transplanting nozzle from the seedling unloading port 12, and the seedlings are planted in the soil by the transplanting nozzle and the matched planting mechanism.

[0041] The seedling cup 1 and the single-door 2 can be made of plastic die-casting to save cost and reduce weight, so that the elastic element 21 can act on the single-door 2 and make it in a normally closed posture.

[0042] In order to ensure that the seedling cup 1 can be stably installed on the transmission component of the agricultural transplanting machine, the following technical solutions are provided.

[0043] The outer side wall of the seedling cup 1 is fixedly connected with a backing plate 14, and the backing plate 14 is provided with an assembly through hole 141. The seedling cup 1 is fixedly installed on the transmission component by a bolt assembly 142 arranged through the assembly through hole 141.

[0044] The setting of the backing plate 14 can effectively increase the thickness of the seedling cup 1, thereby ensuring the stability of the bolt assembly 142. The seedling cup 1 is fixed to the transmission component by bolts, which facilitates disassembly, replacement and maintenance.

[0045] The backing plate 14 and the assembly through hole 141 arranged thereon are provided with two groups of symmetrically arranged assembly through holes on different outer wall surfaces of the seedling cup 1, so as to provide two pairs of mounting points to cope with different forms of transmission components or mechanical arms, thereby improving the universality of the seedling cup 1.

[0046] In order to ensure that the mechanical arm matched on the agricultural transplanting machine can stably transfer the seedlings in the seedling tray to the seedling cup 1, the following technical solutions are provided.

[0047] The top of the seedling cup body 1 is provided with a gap 15, and the gap 15 is arranged on one side of the seedling loading port 11.

[0048] The gap 15 can avoid the interference between the seedling cup body 1 and the running mechanical arm, so that the mechanical arm can run through the gap 15 to the seedling loading port 11, thereby ensuring that the seedling can be stably transferred to the seedling cup body 1.

[0049] Since the running path of the mechanical arm and the running path of the transmission component at the seedling tray position are perpendicular, in order to ensure that the seedling cup body 1 can be stably installed on the transmission belt or transmission chain of the transmission component, and the mechanical arm can stably transfer the seedling, the direction of the gap 15 is perpendicular to the plane of the mounting pad 14.

[0050] In order to ensure that the driving member 23 can be stably assembled on the assembly pin shaft 22, and ensure that the driving member 23 can be smoothly matched with the acting member 3 to control the opening and closing posture of the single door 2, the following technical solutions are provided.

[0051] The driving member 23 is rotatably installed on the assembly pin shaft 22, and the assembly pin shaft 22 is provided with a first gasket 221 and a first pin 222 for positioning the driving member 23, and the driving member 23 adopts a rotating bearing.

[0052] The assembly pin shaft 22 is also provided with two groups of concentric arrangements, and is respectively assembled to the two groups of symmetrically arranged side walls of the single door 2. In addition, the assembly pin shaft 22 is perpendicular to the plane of the pad 14. In actual application, only one of the two groups of assembly pin shafts 22 is provided with a driving member 23, and the bolt assembly 142 and the driving member 23 are respectively assembled to opposite positions, which can be respectively associated with the transmission component and the acting member 3 arranged at different positions, to avoid the spatial motion interference between the transmission component and the acting member 3.

[0053] The driving member 23 can also adopt a freely rotating circular structure such as a wheel, which can ensure that the driving member 23 is stably rotated on the assembly pin shaft 22, and when the acting member 3 contacts, the running driving member 23 can effectively reduce the friction between the acting member 3, thereby ensuring the smoothness of the opening and closing posture of the single door 2.

[0054] A first insertion hole is arranged on the assembly pin shaft 22, which can stably insert the first pin 222 on the assembly pin shaft 22, and effectively limit the first gasket 221 on the inner side of the first insertion hole. The arrangement of the first gasket 221 can avoid the direct contact between the driving member 23 and the first pin 222, which affects the running stability.

[0055] In order to ensure that the acting element 3 can effectively cooperate with the running driving element 23, realize effective control on the opening posture of the single door 2, and realize effective control on the closing posture of the single door 2 under the cooperation of the elastic element 21, the following technical scheme is provided.

[0056] The acting element 3 comprises a flat section 31 and a first inclined section 32 and a second inclined section 33 arranged on both sides of the flat section 31, and the outer edge parts of the flat section 31, the first inclined section 32 and the second inclined section 33 are in contact with the driving element 23.

[0057] The acting element 3 is cut from a steel plate and fixed to the frame of the agricultural transplanting machine, and arc transition surfaces are arranged at the ends of the first inclined section 32 and the second inclined section 33 to ensure stable transfer of the driving element 23 between the first inclined section 32, the flat section 31 and the second inclined section 33.

[0058] When the single door 2 runs to the acting element 3 with the transmission component, the driving element 23 on the single door 2 first contacts the first inclined section 32, and under the action of the first inclined section 32, the driving element 23 and the single door 2 are overturned as a whole, and then the single door 2 is in an open posture, when the driving element 23 runs to the flat section 31, the single door 2 is continuously in an open posture, so as to ensure that the seedlings in the seedling cup body 1 have enough time to transfer to the lower transplanting nozzle, and then the driving element 23 runs to the second inclined section 33, the second inclined section 33 is symmetrically arranged with the first inclined section 32, and then the single door 2 is gradually closed.

[0059] In order to ensure that the single door 2 can be stably installed in a relative rotating posture, and ensure that the single door 2 can cooperate with the clamping plate 13 to effectively block the seedling discharging port 12, the following technical scheme is provided.

[0060] The bottom side wall of the seedling cup body 1 is fixedly connected with an ear seat A16, and the top of the single door 2 is fixedly connected with an ear seat B24, the ear seat A16 and the ear seat B24 are coaxially arranged and are inserted with a positioning pin shaft 25, and the end of the positioning pin shaft 25 is provided with a second gasket 251 and a second locking pin 252.

[0061] The matching design of the ear seat A16 and the ear seat B24 can ensure that the positioning pin shaft 25 is stably inserted into the axis thereof, thereby ensuring that the single door 2 stably runs around the positioning pin shaft 25 at the bottom of the seedling cup body 1, and realizing the adjustment of the opening and closing postures thereof, a second insertion hole is arranged at the end of the positioning pin shaft 25 in a radial direction, so that the second locking pin 252 is stably inserted therein and effectively limits the second gasket 251 inside it, and the arrangement of the second gasket 251 can avoid the second locking pin 252 directly contacting the ear seat A16 or the ear seat B24 to affect the running stability.

[0062] Since the opening and closing posture of the single door 2 is realized by the driving element 23 installed on the assembly pin shaft 22, it is necessary to ensure that the assembly pin shaft 22 and the positioning pin shaft 25 are in parallel arrangement. The ear seat A16, the ear seat B24 and the assembly pin shaft 22 are provided with reinforced structures at the connection positions of the seedling cup body 1 or the single door 2 to ensure the overall structural strength.

[0063] In order to ensure that the elastic element 21 can be stably assembled and exert a stable force on the single door 2 to keep it in a normally closed state, the following technical solutions are provided.

[0064] The elastic element 21 is a torsion spring which is sleeved on the outer periphery of the positioning pin shaft 25, and the two ends of the torsion spring are in abutment with the seedling cup body 1 and the single door 2 respectively.

[0065] The positioning pin shaft 25 can ensure the normal installation of the torsion spring, and the torsion spring exerts a force on the single door 2 to rotate towards the side of the clamping plate 13, so as to realize the abutting arrangement of the single door 2 and the clamping plate 13, and keep the seedling discharging opening 12 in a normally closed posture.

Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.
