Description

Technical Field

[0001] This application relates to the field of agricultural seedling equipment technology, and more specifically, to a seedling tray seedling extraction device with adjustable row spacing. Background Technology

[0002] In modern agricultural seedling production, seedling trays are widely used.

[0003] Removing seedlings from seedling trays is a crucial step in the seedling process. The operation method needs to be flexibly adjusted according to the growth status of the seedlings and the moisture of the substrate to ensure the survival rate and healthy growth of the seedlings. Therefore, a seedling removal device is needed to take the seedlings out of the seedling trays.

[0004] Most existing seedling removal devices are designed for seedling trays with specific row spacing. Different crops and different planting methods use different row spacings for seedling trays. If seedling removal is required for trays with different row spacings, multiple seedling removal devices of different specifications are needed. Existing seedling removal devices do not have the function of removing seedlings according to the row spacing of the seedling tray. Frequent replacement of seedling removal devices will reduce the efficiency of seedling removal operations, thus delaying the farming season and increasing the production cost of seedling removal. Utility Model Content

[0005] The purpose of this invention is to provide a seedling tray seedling retrieval device with adjustable row spacing, so as to at least solve the technical problem that related seedling retrieval devices do not have the ability to adaptively retrieve seedlings according to the row spacing of the seedling tray.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] A seedling tray dispensing device with adjustable row spacing includes:

[0008] The row spacing adjustment mechanism is located on the inner side of the top of the support frame. The mechanism includes a support plate mounted on the top of the support frame. A lead screw is rotatably mounted on one side of the inner side of the support plate. A limit rod is fixedly mounted on the lower side of the support plate near the lead screw. A threaded sleeve seat is slidably fitted onto the surface of the limit rod, and the threaded sleeve seat is threaded onto the surface of the lead screw. Multiple sets of guide plates are fixedly mounted at the bottom of the threaded sleeve seat via a connecting frame. Adjacent sets of guide plates are connected by corresponding telescopic frames. Telescopic sleeve rods are fixedly mounted on the top of the ends of the multiple sets of guide plates away from the threaded sleeve seat, and the top of the telescopic sleeve rods is connected to the corresponding mounting plate.

[0009] The seedling taking mechanism is used for taking seedlings from seedling trays. Multiple seedling taking mechanisms are connected and installed on corresponding mounting plates.

[0010] Preferably, the telescopic sleeve includes a support rod, the bottom end of which is connected to the end of the guide plate, the upper part of which slides axially into the support sleeve, and the top end of the support sleeve has a connecting block that is connected to the corresponding mounting plate. When adjacent guide plates move closer or further apart, they simultaneously move the corresponding mounting plates closer or further apart.

[0011] Preferably, a first connecting horizontal plate is slidably and liftably mounted on the support upright plate. The first connecting horizontal plate is fixedly connected to the support beam. The support beam is also slidably and liftably mounted on the support upright plate. An electric telescopic rod is provided on the support upright plate for adjusting the height of the support beam and the first connecting horizontal plate.

[0012] Preferably, two adjacent guide plates are connected by a telescopic frame, wherein a single telescopic frame is a scissor bar structure formed by two midpoints hinged together, and multiple scissor bars are connected end to end to realize the adjustment of the distance between two adjacent guide plates.

[0013] Preferably, the seedling taking mechanism includes multiple sets of sliding supports, which are arranged in an equidistant sliding connection inside the second connecting horizontal plate, and the second connecting horizontal plate is fixedly connected to the telescopic end of the hydraulic rod.

[0014] The hydraulic rod is fixedly inserted into the center of the support beam.

[0015] Preferably, a rack is fixedly connected to one side of each set of sliding support surfaces;

[0016] Each mounting plate is rotatably equipped with two opposing half-gears, which mesh with the two tooth surfaces of the rack respectively.

[0017] Preferably, a slider is fixedly installed at the bottom of each sliding support, and a groove is opened inside each mounting plate, with the bottom of the slider slidably installed inside the groove.

[0018] Compared with the prior art, the technical advantages of the adjustable row spacing seedling tray seedling taking device of this application are as follows:

[0019] First, this utility model, through the setting of multiple sets of telescopic frames, drives multiple sets of guide plates to move synchronously and at equal distances, thereby adjusting the row spacing adjustment mechanism according to the row spacing of the seedling trays, so as to further adjust the distance between two adjacent sets of guide plates and two adjacent sets of telescopic sleeves, so that the distance between multiple seedling taking mechanisms matches the position of the corresponding seedling trays.

[0020] Secondly, this utility model uses a hydraulic rod to drive the second connecting horizontal plate to move in parallel. The movement of the second connecting horizontal plate drives multiple sets of sliding supports to move synchronously. The movement of the multiple sets of sliding supports drives multiple sets of sliders to slide inside multiple sets of sliding grooves. The sliding of the multiple sets of sliders drives multiple sets of racks to move in parallel. The movement of the multiple sets of racks drives multiple sets of half gears to rotate through meshing. The rotation of the half gears drives multiple sets of seedling grabbers to move closer to each other, thereby grabbing the seedlings in the seedling tray and realizing the seedling grabbing action.

[0021] Therefore, the technical problem that related seedling-taking devices do not have the ability to adaptively take seedlings according to the row spacing of the seedling trays has been solved. Attached Figure Description

[0033] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0035] like Figures 1 to 4 As shown, in this embodiment, a seedling tray seedling taking device with adjustable row spacing is provided, including a support frame 1;

[0036] The inner side of the top of the support frame 1 is provided with a row spacing adjustment mechanism 2 for adjusting the row spacing according to the seedling trays;

[0037] Specifically, in this embodiment, the row spacing adjustment mechanism 2 includes a support plate 201 fixedly installed on the top of the support frame 1. A lead screw 202 is rotatably installed on one side of the inner side of the support plate 201. A limit rod 203 is fixedly installed on the lower side of the support plate 201 near the lead screw 202. A threaded sleeve seat 204 is slidably fitted on the surface of the limit rod 203, and the threaded sleeve seat 204 is threadedly fitted on the surface of the lead screw 202. Based on the rotation of the lead screw 202, the threaded sleeve seat 204 can move along the axial direction of the limit rod 203.

[0038] Furthermore, a servo motor 207 is fixedly installed on one side of the outer wall of the support plate 201 via a mounting base. The output end of the servo motor 207 passes through the interior of the support plate 201 and is fixedly connected to one end of the lead screw 202. Multiple sets of guide plates 205 are fixedly installed at the bottom end of the lead sleeve seat 204 via a connecting frame.

[0039] Optionally, multiple sets of guide plates 205 are located below the limiting rod 203;

[0040] In this embodiment of the application, two adjacent sets of guide plates 205 are connected by corresponding telescopic frames 206;

[0041] In this embodiment of the application, a telescopic sleeve rod 208 is fixedly installed on the top of the end of the multiple guide plates 205 away from the thread sleeve seat 204, and the top of the telescopic sleeve rod 208 is connected to the corresponding mounting plate 306.

[0042] Specifically, the telescopic sleeve 208 includes a support rod 2082, the bottom end of which is connected to the end of the guide plate 205, and the upper part of the support rod 2082 slides axially into the support sleeve 2081. The top end of the support sleeve 2081 has a connecting block 2083, which is connected to the corresponding mounting plate 306. When adjacent guide plates 205 move closer or further away from each other, the corresponding mounting plates 306 are simultaneously moved closer or further away from each other.

[0043] Furthermore, a first connecting horizontal plate 209 is slidably mounted on the support plate 201. The first connecting horizontal plate 209 is fixedly connected to the support beam 301. The support beam 301 is also slidably mounted on the support plate 201. An electric telescopic rod 4 is provided on the support plate 201 for adjusting the height of the support beam 301 and the first connecting horizontal plate 209.

[0044] In specific implementation, the servo motor 207 first drives the lead screw 202 to rotate. The rotation of the lead screw 202 causes the lead sleeve seat 204 to slide along the axial direction of the lead screw 202 on the inner side of the support plate 201. When the lead sleeve seat 204 slides, the multiple sets of telescopic frames 206 drive the multiple sets of guide plates 205 to move synchronously and equidistantly. Thus, the row spacing adjustment mechanism 2 can be adjusted according to the row spacing of the seedling trays, so as to further adjust the distance between two adjacent sets of guide plates 205 and two adjacent sets of telescopic sleeves 208, thereby realizing the adjustment of the spacing of the seedling taking mechanism 3 to meet the seedling taking needs of different specifications of seedling trays.

[0045] Preferably, in the specific implementation of the telescopic frame 206, two adjacent guide plates 205 are connected by a telescopic frame 206. The single telescopic frame 206 is a scissor bar structure formed by two midpoints being hinged to each other. Multiple scissor bars are connected end to end to realize the adjustment of the distance between two adjacent guide plates 205.

[0046] like Figure 1 , Figure 3 and Figure 4 As shown in the present disclosure, the adjustable row spacing seedling tray seedling taking device of the present disclosure further includes a seedling taking mechanism 3 for taking seedlings from the seedling tray, wherein multiple seedling taking mechanisms 3 are respectively connected and installed on corresponding mounting plates 306.

[0047] In this embodiment of the utility model, the seedling taking mechanism 3 includes multiple sets of sliding supports 304. The multiple sets of sliding supports 304 are arranged in an equidistant sliding connection inside the second connecting horizontal plate 303. The second connecting horizontal plate 303 is fixedly connected to the telescopic end of the hydraulic rod 302. The hydraulic rod 302 is fixedly inserted into the center of the support beam 301.

[0048] In addition, a rack 308 is fixedly connected to one side of the surface of each set of sliding supports 304, and the rack 308 has two tooth surface structures.

[0049] Each mounting plate 306 has two opposing half-gears 309 rotatably mounted on it. The two half-gears 309 mesh with the two tooth surfaces of the rack 308 respectively. When the rack 308 moves, it drives the two half-gears 309 to rotate synchronously by a certain angle. Each half-gear 309 is fixedly connected to a seedling clamp 310 at its end. When the two half-gears 309 rotate synchronously by a certain angle, the two seedling clamps 310 can perform a grasping action or a releasing action.

[0050] Preferably, the bottom end of each sliding support 304 is fixedly installed with a slider 305, and the inside of each mounting plate 306 is provided with a groove 307, and the bottom end of the slider 305 is slidably installed inside the groove 307.

[0051] Preferably, the lower end of the seedling clip 310 has a pointed part. When taking seedlings, the pointed part of the seedling clip 310 is inserted into the soil in the seedling tray, and the seedling clips 310 that are close together can take out the seedlings.

[0052] It is understood that, after adjustment, in this embodiment of the application, the hydraulic rod 302 drives the second connecting horizontal plate 303 to move in parallel. The movement of the second connecting horizontal plate 303 drives multiple sets of sliding supports 304 to move synchronously. The movement of the multiple sets of sliding supports 304 drives multiple sets of sliders 305 to slide inside multiple sets of sliding grooves 307. The sliding of the multiple sets of sliders 305 drives multiple sets of racks 308 to move in parallel. The movement of the multiple sets of racks 308 drives multiple sets of half gears 309 to rotate through meshing. The rotation of the multiple sets of half gears 309 drives multiple sets of seedling clamps 310 to move closer to each other, thereby grabbing the seedlings in the seedling tray and realizing the seedling retrieval action.

[0053] In one optional embodiment, when implementing this embodiment, a protective cover structure for protecting the rack 308 and the half gear 309 can be provided on the mounting plate 306 as needed.

[0054] Based on the above embodiments, the specific working principle of the adjustable row spacing seedling tray seedling taking device of this application is described as follows:

[0055] The seedling taking device in this embodiment of the application is provided with a support plate 201, and each of the four corners of the support plate 201 is provided with a movable wheel, which allows the seedling taking device to move above a row of seedling trays.

[0056] Then, when the servo motor 207 makes the thread sleeve seat 204 slide, the multiple sets of telescopic frames 206 drive the multiple sets of guide plates 205 to move synchronously and equidistantly. Thus, the row spacing adjustment mechanism 2 can be adjusted according to the row spacing of the seedling tray, so as to further adjust the distance between two adjacent sets of guide plates 205 and two adjacent sets of telescopic sleeve rods 208, so that the distance between multiple seedling taking mechanisms 3 matches the position of the corresponding seedling tray.

[0057] Next, using the electric telescopic rod 4, the supporting crossbeam 301 and the first connecting crossbeam 209 are simultaneously adjusted to their respective heights, causing them to move downwards. This allows multiple seedling-picking mechanisms 3 to move downwards simultaneously, meaning that the corresponding seedling-picking clips 310 on the mounting plate 306 move downwards, allowing the tips of the seedling-picking clips 310 to insert into the soil of the corresponding seedling trays. The hydraulic rod 302 then drives the second connecting crossbeam 303 to move parallel. The movement of the second connecting crossbeam 303 drives multiple sets of sliding supports 304 to move synchronously. The movement of the multiple sets of sliding supports 304 drives multiple sets of sliders 305 to slide inside multiple sets of sliding grooves 307. The sliding of the multiple sets of sliders 305 drives multiple sets of racks 308 to move parallel. The movement of the multiple sets of racks 308, through meshing, drives multiple sets of half gears 309 to rotate. The rotation of the half gears 309 causes the multiple sets of seedling-picking clips 310 to move closer to each other, thereby grabbing the seedlings in the seedling trays and realizing the seedling-picking action.

[0058] It is understood that in this embodiment of the disclosure, the telescopic frame 206 provided is a scissor structure, and the cross angle can be adjusted according to actual needs to further adjust the distance between adjacent guide plates 205 and adjacent telescopic sleeves 208, thereby realizing the adjustment of the distance of the seedling taking mechanism 3 to adapt to the seedling taking needs of seedling trays of different specifications.

[0059] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
