[0049] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0050] In one embodiment, such as Figures 1-7As shown, a strawberry elevated seedling raising device includes a fixed support 1. Two support seats 5 are symmetrically fixedly connected to the outer wall of the fixed support 1. Multiple seedling bed bodies 4 are arranged horizontally and equidistantly above the fixed support 1. The multiple seedling bed bodies 4 are all located above the two support seats 5. The fixed support 1 is provided with a pushing mechanism for pushing the multiple seedling bed bodies 4 to rise and fall.

[0051] The pushing mechanism includes: a movable frame 2010 set inside the fixed support 1. The movable frame 2010 is C-shaped and located below the main body 4 of the seedling bed. A double-headed motor 205 is installed inside the movable frame 2010. Two linear guide rails 209 are symmetrically installed on the outer wall of the movable frame 2010. Both linear guide rails 209 are fixedly connected to the fixed support 1.

[0052] The support base 5 is equipped with a support mechanism for supporting the main body 4 of the seedling bed;

[0053] The support mechanism includes: a sliding component disposed on the support base 5;

[0054] The sliding assembly includes: multiple movable pressure plates 304 that are horizontally and equidistantly arranged inside the support base 5. The multiple movable pressure plates 304 all extend to the outside of the end of the support base 5 near the fixed bracket 1. The multiple movable pressure plates 304 are slidably connected to the support base 5. The multiple movable pressure plates 304 are respectively located below the multiple seedling bed bodies 4.

[0055] The movable pressure plate 304 is equipped with a locking assembly;

[0056] In this embodiment, during use, the linear guide rail 209 can be activated to drive the movable frame 2010 to move laterally. When the movable frame 2010 moves to the bottom of a seedling bed body 4, the pushing mechanism can push the seedling bed body 4 to rise, and the supporting mechanism can limit the rise of the seedling bed body 4, thereby providing stable support for the seedling bed body 4.

[0057] When the main body 4 of the seedling bed rises to the designated height, the above operation is reversed, so that the moving frame 2010 can be moved to the bottom of the next main body 4 of the seedling bed, thereby raising the height of multiple main bodies 4 of the seedling bed in sequence.

[0058] When it is necessary to lower the height of the main body 4 of the seedling bed, the limiting support of the main body 4 of the seedling bed can be released through the cooperation of the pushing mechanism and the supporting mechanism. Then, the supporting mechanism can drive the main body 4 of the seedling bed to descend stably, so that the height of multiple main bodies 4 of the seedling bed can be conveniently adjusted.

[0059] In one embodiment, such as Figures 1-4 As shown, the pushing mechanism also includes a docking component disposed on the mobile frame 2010;

[0060] The docking assembly includes: a lifting push plate 207 set on the upper surface of the movable frame 2010, a docking block 208 fixedly connected to the top of the lifting push plate 207, the outer wall of the top of the docking block 208 being hemispherical, and multiple docking sleeves 201 being arranged horizontally and equidistantly above the lifting push plate 207, the multiple docking sleeves 201 being fixedly connected to multiple seedling bed bodies 4 respectively, and one docking sleeve 201 being fitted onto the outer wall of the docking block 208;

The hydraulic push rod 2011 is located on one side of the dual-head motor 205. The lifting push plate 207 is fixedly connected to the output end of the hydraulic push rod 2011. Through the cooperation of the docking component and the pushing component, the main body of the seedling bed 4 can be driven to rise and fall stably.

[0064] In one embodiment, such as Figures 1-7 As shown, the moving assembly includes: two lead screws 2012 symmetrically rotatably connected to the outer wall of the moving frame 2010; a guide bracket 2013 is provided below each of the two lead screws 2012; the guide bracket 2013 is fixedly connected to the lead screw 2012; a moving push plate 203 is sleeved on the outer wall of each of the two lead screws 2012; the moving push plate 203 is threadedly connected to the lead screw 2012; a roller 202 is rotatably connected to the end of the moving push plate 203 away from the moving frame 2010; and the moving push plate 203 is slidably sleeved on the outer wall of the guide bracket 2013.

[0065] A transmission assembly is installed on the lead screw 2012;

[0066] The transmission assembly includes two transmission wheels 206 symmetrically arranged on the outside of the movable frame 2010. The two transmission wheels 206 are fixedly connected to the two output ends of the dual-head motor 205 respectively. The outer walls of the two transmission wheels 206 are meshed with synchronous belts 204. The inner wall of the synchronous belt 204 away from the transmission wheels 206 is meshed with a transmission ring 2014. The transmission ring 2014 is fixedly connected to the outer wall of the lead screw 2012. Through the cooperation between the movable assembly and the transmission assembly, the limiting support of the support mechanism on the seedling bed body 4 can be released by squeezing the movable pressure plate 304.

[0067] In one embodiment, such as Figures 1-6As shown, the locking assembly includes: two positioning plates 306 symmetrically arranged on the outside of the movable pressure plate 304; each of the two positioning plates 306 is provided with a lifting slide plate 301 on the side away from the movable pressure plate 304; the lifting slide plate 301 passes through the support base 5 and is fixedly connected to the seedling bed body 4; a plurality of positioning blocks 309 are vertically and equidistantly formed on one side of the outer wall of the lifting slide plate 301; the upper surface of the positioning block 309 is inclined; a positioning groove that matches the outer wall of the positioning block 309 is opened at the position where the positioning plate 306 and the positioning block 309 meet; the lifting slide plate 301, the positioning plate 306, and the positioning block 309 are all slidably connected to the support base 5.

[0068] A limit component is provided on the positioning plate 306;

[0069] The limiting component includes: multiple connecting slide rods 307 that are vertically and equidistantly fixed to one side of the positioning plate 306; a movable slider 305 is fixedly connected to the side of the multiple connecting slide rods 307 away from the lifting slide plate 301; and a movable pressure plate 304 is slidably sleeved on the outer wall of the movable slider 305.

[0070] A reset component is provided on the connecting slide bar 307;

[0071] A guide component is provided on the movable slider 305;

[0072] The reset component is a spring 308 sleeved on the outer wall of the connecting slide bar 307. One end of the spring 308 contacts the outer wall of the positioning plate 306, and the other end of the spring 308 contacts the outer wall of the movable slider 305. Through the cooperation of the locking component, the limiting component and the reset component, the positioning plate 306 can slide along the inner wall of the support base 5.

[0073] In one embodiment, such as Figure 5 As shown, the guide assembly includes two guide sliders 302 symmetrically fixedly connected to the outer wall of the movable slider 305. The two guide sliders 302 are located at the upper and lower ends of the movable slider 305, respectively. A guide groove 303 is provided at the contact position between the movable pressure plate 304 and the guide slider 302 for the guide slider 302 to slide. Through the mutual cooperation between the guide slider 302 and the guide groove 303, the positioning plate 306 and the positioning block 309 can be driven to separate from each other when the limiting support of the seedling bed body 4 is released.

[0074] The above embodiment discloses a strawberry elevated seedling raising device. In use, the two linear guide rails 209 are activated to drive the moving frame 2010 to move laterally. At this time, the lifting push plate 207, driven by the hydraulic push rod 2011 and the moving frame 2010, drives the docking block 208 to move synchronously until the docking block 208 moves to the bottom of a docking sleeve plate 201. At this time, the linear guide rails 209 are stopped and the hydraulic push rod 2011 is activated to push the lifting push plate 207 to rise. At the same time, the docking block 208 is inserted into the interior of the docking sleeve plate 201 under the push of the lifting push plate 207, thereby realizing the convenient docking of the lifting push plate 207 with a docking sleeve plate 201.

[0075] Then, the hydraulic push rod 2011 pushes the lifting push plate 207 to rise continuously. At this time, the main body 4 of the seedling bed, through the docking sleeve plate 201, is pushed by the lifting push plate 207, and the lifting slide plate 301 drives the positioning block 309 to slide along the inner wall of the support seat 5. At the same time, the positioning plate 306, under the pressure of the outer wall of the positioning block 309, pushes the moving slider 305 to slide along the inner wall of the moving pressure plate 304 through the connecting slide rod 307. At this time, the positioning block 309 separates from the inner wall of a positioning slot by moving, and the positioning plate 306 moves by moving. When the compression spring 308 contracts, the guide slider 302 moves synchronously under the drive of the moving slider 305. At the same time, the moving pressure plate 304 slides along the inner wall of the support seat 5 under the compression guidance of the outer wall of the guide slider 302 through the guide groove 303. When the positioning block 309 moves to the port of the next positioning slot, the spring 308 pushes the positioning plate 306 to engage with the outer wall of the positioning block 309 through rebound. In this way, the seedling bed body 4 can be limited to rise through the engagement connection between the positioning plate 306 and the positioning block 309.

[0076] When the main body 4 of the seedling bed rises to the designated height, the hydraulic push rod 2011 is activated to drive the lifting push plate 207 to reset. At the same time, the positioning plate 306 and the positioning block 309 are engaged to provide stable support for the main body 4 of the seedling bed. Then, the linear guide rail 209 is activated to move the moving frame 2010 to the bottom of the next main body 4 of the seedling bed, so that the height of multiple main bodies 4 of the seedling bed can be raised in sequence.

[0077] When it is necessary to lower the height of the main body 4 of the seedling bed, the hydraulic push rod 2011 is activated to insert the docking block 208 into the interior of a docking sleeve 201. Then, the dual-head motor 205 is activated to drive the two transmission wheels 206 to rotate synchronously. At this time, the transmission ring 2014, driven by the synchronous belt 204 and the transmission wheels 206, drives the lead screw 2012 to rotate. Simultaneously, the moving push plate 203, driven by the thread on the outer wall of the lead screw 2012, slides along the outer wall of the guide bracket 2013. The roller 202 moves synchronously under the drive of the moving push plate 203. When the roller 202 contacts the outer wall of the moving pressure plate 304, the moving pressure plate 304... Under compression, the slide is slid along the inner wall of the support base 5. At the same time, the guide slider 302, under the compression guidance of the inner wall of the guide groove 303, moves the positioning plate 306 by moving the slider 305 and the connecting slide rod 307. This allows the positioning plate 306 to separate from the positioning block 309, thereby releasing the limiting support on the seedling bed body 4. Then, the hydraulic push rod 2011 is activated to drive the lifting push plate 207 to descend. At the same time, the seedling bed body 4, through the docking sleeve plate 201, is driven by the lifting push plate 207 to push the lifting slide plate 301 to descend synchronously along the inner wall of the support base 5. This allows the seedling bed body 4 to descend stably, thereby allowing for convenient adjustment of the height of multiple seedling bed bodies 4.

[0078] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
