Description

Technical Field

[0001] This utility model relates to the field of seedling transport devices, specifically to an automatic temperature-controlled seedling transport device that improves seedling survival rate. Background Technology

[0002] Plant seedlings are the initial stage of a plant's growth cycle, typically referring to the young plant from seed germination to the initial formation of roots, stems, and leaves. This stage is extremely sensitive to environmental conditions such as light, water, and temperature. Good growing conditions promote healthy growth and lay a solid foundation for subsequent plant development. Plant seedlings are usually cultivated artificially and then transplanted. Therefore, specialized equipment for transporting plant seedlings is typically used to complete the transportation task.

[0003] Patent document CN218877334U discloses a seedling transport device, including a transport vehicle body with a buffer assembly on the transport vehicle body. The buffer assembly includes a placement block. This seedling transport device places the seedling inside the placement trough, causing the roots of the seedling to press against a water storage bag. This supports the roots of the seedling, preventing uneven force distribution caused by a single support point, which could lead to soil falling off the roots. The water storage bag also protects the roots of the seedling, cushioning them during transport and reducing the impact force between the roots and the transport vehicle body, thus preventing soil from falling off the roots. Simultaneously, a fixing clamp secures the seedling trunk. When the seedling shakes, the fixing clamp moves the buffer block, causing the buffer block to compress a buffer spring. The elastic force of the buffer spring counteracts the shaking force of the seedling, thus achieving a cushioning effect.

[0004] The seedling transport device in the aforementioned patent document requires manual grabbing of the seedlings to remove them from the placement trough. Without a protective film around the seedling roots, this method can cause the soil around the seedling roots to loosen or fall off, damaging the seedling roots and affecting the survival rate of the seedlings after transplanting. Therefore, an automatic temperature-controlled seedling transport device is proposed to improve the survival rate of seedlings and solve the above problems. Utility Model Content

[0005] To address the aforementioned issues, an automatic temperature-controlled seedling transport device is provided to improve seedling survival rates. This device uses a driven pulley to drive a bidirectional lead screw to rotate. Simultaneously, several movable seats mounted on the bidirectional lead screw move closer or further apart, causing a support rod hinged to the movable seats to move longitudinally along a lifting frame. This lifts the seedling out of the storage rack, solving the problem of soil loosening around the seedling roots and damaging the roots during manual removal of seedlings, and preventing seedlings from wilting after transplanting.

[0006] To address the existing technical problems, this utility model provides an automatic temperature-controlled seedling transport device to improve seedling survival rate, including a transport box, a shelf inside the transport box for placing seedlings, a lifting frame inside the shelf for lifting seedlings upwards, and an adjustment mechanism that can be hinged to the lifting frame.

[0007] The adjusting mechanism includes a bidirectional lead screw rotatably mounted at both ends on a transport box, with several support mechanisms mounted on the bidirectional lead screw. Each support mechanism is hinged to the lifting frame. Each support mechanism includes two sets of movable seats threaded onto the bidirectional lead screw. A support rod for longitudinal movement of the lifting frame is hinged to each movable seat, with the end of the support rod furthest from the movable seat hinged to the lifting frame. A slide rail is provided on one side of each movable seat, fixed to the transport box. A sliding groove is also provided on the movable seat, slidably mounted on the slide rail. A rotating shaft is rotatably mounted on the transport box, with a drive pulley fixed to one end. A driven pulley is located inside the transport box, fixed to the bidirectional lead screw. A transmission belt for power transmission is mounted on both the drive pulley and the driven pulley.

[0008] As one technical solution of this utility model, a handle is fixed at the end of the rotating shaft away from the drive pulley.

[0009] As a technical solution of this utility model, the shelf is provided with a placement groove, the inner wall of the placement groove is provided with a clearance groove, the support frame is provided inside the placement groove, and the support frame is provided with a limiting rod that can slide and cooperate with the clearance groove in the longitudinal direction.

[0010] As a technical solution of this utility model, the transport box is also provided with a boss, the inside of the boss is provided with a water storage chamber for storing water, the inside of the boss mounting groove is provided with a water pump, the bottom of the water pump is provided with a bottom pipe for drawing water out of the water storage chamber, the output end of the water pump is provided with a water pipe that can extend into the inside of the transport box, and several nozzles are equidistantly arranged on the water pipe.

[0011] As a technical solution of this utility model, the top of the protrusion is provided with a cooling and heating air device, the output end of the cooling and heating air device is provided with an air pipe that can extend into the inside of the transport box, and an electromagnetic valve is provided on the air pipe.

[0012] As one technical solution of this utility model, the top of the boss is provided with a controller that can be electrically connected to the water pump and the heating / cooling air device.

[0013] As a technical solution of this utility model, a number of temperature sensors are provided on the inner wall of the transport box, and the temperature sensors are electrically connected to the controller.

[0014] The advantages of this utility model compared to the prior art are:

[0015] 1. This application utilizes a rotating shaft to drive the active pulley to rotate, which in turn drives the driven pulley via a transmission belt. This drives the driven pulley to rotate the bidirectional lead screw. Simultaneously, several movable seats mounted on the bidirectional lead screw move closer or further apart, causing the support rods hinged to the movable seats to move longitudinally along the connecting support frame. This allows the support frame to lift the seedling out of the shelf, solving the problem that manually removing seedlings from the shelf can easily cause the soil around the seedling roots to loosen, leading to root damage. This also prevents the seedlings from wilting after transplanting.

[0016] 2. This application provides a placement groove for the support frame on a shelf, with several clearance grooves on the side of the placement groove. The support frame is then horizontally installed inside the placement groove, and several limiting rods are longitudinally installed on the support frame. The limiting rods can slide within the clearance grooves. When the support frame moves longitudinally, the limiting rods slide along the inner wall of the clearance groove, ensuring that the support frame remains horizontal while moving. When the support frame lifts the seedling out of the placement groove, the limiting rods can bind the soil around the seedling roots, solving the problem of loose soil and preventing damage to the seedling roots caused by loose soil.

[0028] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0029] See Figures 1-10 As shown, an automatic temperature-controlled seedling transport device for improving seedling survival rate includes a transport box 1, a shelf 21 for placing seedlings inside the transport box 1, a lifting frame 22 for lifting seedlings upward inside the shelf 21, and an adjustment mechanism 23 that can be hinged to the lifting frame 22.

[0030] The adjusting mechanism 23 includes a bidirectional lead screw 231 rotatably mounted on the transport box 1 at both ends. Several support mechanisms 232 are provided on the bidirectional lead screw 231, and the support mechanisms 232 are hinged to the lifting frame 22. Each support mechanism 232 includes two sets of movable seats 2321 threaded onto the bidirectional lead screw 231. A support rod 2322 for longitudinal movement of the lifting frame 22 is hinged to the movable seat 2321. One end of the support rod 2322 away from the movable seat 2321 is hinged to the lifting frame 22. One end of the movable seat 2321… A slide rail 2324 is provided on the side and fixed to the transport box 1. A slide groove 2323 is also provided on the movable seat 2321 and slidably installed on the slide rail 2324. A rotating shaft 234 is rotatably installed on the transport box 1. A drive pulley 236 is fixed at one end of the rotating shaft 234. A driven pulley 233 is provided on the inner side of the transport box 1 and fixed to the double-acting screw 231. A transmission belt 237 for transmission is provided on the drive pulley 236 and the driven pulley 233.

[0031] In use, rotating the rotating shaft 234 causes the driving pulley 236 to rotate, which in turn drives the driven pulley 233 via the transmission belt 237. This drives the bidirectional lead screw 231 to rotate. Simultaneously, several movable seats 2321 mounted on the bidirectional lead screw 231 move closer or further apart, causing the support rod 2322 hinged to the movable seat 2321 to move the lifting frame 22 longitudinally. This allows the lifting frame 22 to lift the seedling out of the shelf 21, preventing the soil around the seedling roots from loosening and damaging the roots when the seedlings are manually removed from the shelf 21. When the bidirectional lead screw 231 rotates and drives the threaded movable seat 2321 to slide, the movable seat 2321 slides linearly along the slide rail 2324 via the slide groove 2323, preventing the movable seat 2321 from rotating with the bidirectional lead screw 231.

[0032] See Figure 2 , Figure 4 , Figure 7 and Figure 9 As shown, a handle 235 is fixed to the end of the rotating shaft 234 away from the drive pulley 236.

[0033] In use, by fixing the handle 235 to the end of the rotating shaft 234 away from the drive pulley 236, the handle 235 drives the rotating shaft 234 to rotate, and then the rotating shaft 234 drives the drive pulley 236 to rotate.

[0034] See Figure 2 , Figure 6 and Figure 7As shown, the shelf 21 is provided with a placement groove 211, and the inner wall of the placement groove 211 is provided with a clearance groove 212. The support frame 22 is provided inside the placement groove 211, and the support frame 22 is provided with a limiting rod 221 that can slide and cooperate with the clearance groove 212.

[0035] In use, a placement groove 211 for placing the lifting frame 22 is provided on the shelf 21, and several clearance grooves 212 are provided on the side of the placement groove 211. The lifting frame 22 is then horizontally installed inside the placement groove 211. Several limiting rods 221 are longitudinally provided on the lifting frame 22. The limiting rods 221 can slide in the clearance grooves 212. When the lifting frame 22 moves longitudinally, the limiting rods 221 slide along the inner wall of the clearance grooves 212, so that the lifting frame 22 is always in a horizontal state while moving. When the lifting frame 22 lifts the seedling out of the placement groove 211, the limiting rods 221 can bind the soil around the seedling roots.

[0036] See Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 8 As shown, the transport box 1 is also provided with a boss 3. The inside of the boss 3 is provided with a water storage chamber 31 for storing water. The inside of the mounting groove of the boss 3 is provided with a water pump 32. The bottom of the water pump 32 is provided with a bottom pipe 321 for drawing water out of the water storage chamber 31. The output end of the water pump 32 is provided with a water pipe 33 that can extend into the transport box 1. Several nozzles 34 are equidistantly arranged on the water pipe 33.

[0037] When in use, the water pump 32 draws water from the water storage chamber 31 through the bottom pipe 321, and then the water pump 32 delivers the water to the water pipe 33, so that the several nozzles 34 set on the water pipe 33 spray water into the transport box 1, so as to irrigate the seedlings and prevent the seedlings from withering due to lack of water during transportation.

[0038] See Figures 2 to 5 and Figure 8 As shown, a cooling and heating air device 35 is provided at the top of the boss 3. The output end of the cooling and heating air device 35 is provided with an air pipe 351 that can extend into the inside of the transport box 1. A solenoid valve 352 is provided on the air pipe 351.

[0039] In use, air is heated or cooled by the air-cooling device 35 and then delivered to the interior of the transport box 1 through the air pipe 351 to heat or cool the interior of the transport box 1. The solenoid valve 352 is used to open or close to control the flow rate of heated or cooled air delivered to the transport box 1 through the air pipe 351.

[0040] See Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 8 As shown, the top of the boss 3 is provided with a controller 37 that can be electrically connected to the water pump 32 and the heating / cooling air device 35.

[0041] In use, by installing the controller 37 on the top of the boss 3, the controller 37 can be electrically connected to the water pump 32 and the cooling and heating device 35 respectively, so that the controller 37 can control the water pump 32 and the cooling and heating device 35 to start and stop simultaneously or individually.

[0042] See Figures 2 to 5 and Figure 8 As shown, several temperature sensors 36 are installed on the inner wall of the transport box 1, and the temperature sensors 36 are electrically connected to the controller 37.

[0043] In use, the temperature sensor 36 is fixed to the inner wall of the transport box 1 and electrically connected to the controller 37, so that the temperature sensor 36 can monitor the temperature inside the transport box 1 and transmit the monitoring data to the controller 37 in real time.

[0044] In this application, the seedling is placed on the support frame 22. The manual operation handle 235 causes the rotating shaft 234 to rotate, driving the drive pulley 236 to rotate. The drive pulley 236 then drives the driven pulley 233 and the double-acting screw 231 to rotate via the transmission belt 237. This causes the bottoms of several support mechanisms 232 mounted on the double-acting screw 231 to move closer or further away simultaneously. As a result, the support mechanisms 232 drive the support frame 22 to move longitudinally, so that the support frame 22 can carry the seedling into or out of the storage rack 21. By fixing the temperature sensor 36 to the inner wall of the transport box 1 and electrically connecting the temperature sensor 36 to the controller 37, the temperature sensor 36 can monitor the transport box. The internal temperature is monitored, and the temperature sensor 36 transmits the monitoring data to the controller 37 in real time. Then, the transmission belt 237 controls the start of the cooling and heating air device 35, so that the warm or cold air generated by the cooling and heating air device 35 is delivered to the inside of the transport box 1 through the air pipe 351, thereby keeping the temperature inside the transport box 1 constant. Then, the controller 37 controls the water pump 32 to draw water stored in the water storage chamber 31 through the bottom pipe 321, and then deliver it to the water pipe 33. The water is then sprayed into the inside of the transport box 1 through the nozzle 34 on the outside of the water pipe 33 to irrigate the seedlings, thus completing the use of an automatic temperature-controlled seedling transport device to improve the survival rate of seedlings.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
