Description

Technical Field

[0001] This utility model relates to the field of seedling equipment technology, specifically a dual-station seedling box conveying and lifting device. Background Technology

[0002] In the modern seedling industry, the conveying and transfer of seedling boxes is a crucial link in the seedling production line. Traditional seedling box conveying systems mostly use single-station conveyor devices, which can only transport and perform simple processing on a single seedling box, resulting in low efficiency and difficulty in meeting the production needs of large-scale seedling production. With the continuous development of the seedling industry, higher demands are being placed on the automation level and operational efficiency of seedling equipment, and dual-station or multi-station conveyor devices are gradually becoming a research hotspot.

[0003] Current dual-station seedling box conveying devices often struggle to maintain stable lifting operations while fulfilling their conveying function. Some devices use a single cylinder for direct lifting, which can lead to uneven force distribution during lifting, causing the seedling box to tilt or even fall over, affecting the growth of the seedlings inside. Other devices suffer from interference between the conveying and lifting mechanisms; unreasonable layouts of the conveyor chains or roller conveyor platforms can cause jamming during the switching between conveying and lifting, reducing the overall smoothness and reliability of the operation. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a dual-station seedling box conveying and lifting device, which aims to solve the problems of unsmooth conveying and unstable lifting of existing dual-station seedling box conveying and lifting devices.

[0005] This utility model provides the following technical solution:

[0006] Furthermore, the dual-station seedling box conveying and lifting device includes a base, on which two roller conveyor platforms are arranged horizontally on the base. A lifting plate is provided on the base, and several uprights are arranged longitudinally on the lifting plate. Each upright is located between two adjacent conveyor rollers on the two roller conveyor platforms. A conveyor chain is rotatably mounted on the uprights. A chain drive mechanism for driving the conveyor chain to rotate synchronously is provided on the lifting plate. Sliding sleeves are provided on the top plate of the base at the four corners corresponding to the lifting plate. Sliding rods are provided inside the sliding sleeves. The upper part of the sliding rods is connected to the corresponding position of the lifting plate. A lifting drive mechanism for driving the four sliding rods to move upward synchronously is provided below the base.

[0007] Furthermore, the lifting drive mechanism includes a pair of left and right linkage shafts that are rotatably installed. Both ends of the linkage shafts are provided with linkage plates. The linkage plates are rotatably connected to the lower part of the corresponding slide rods through short blocks. A rotating plate is provided in the middle of the linkage shafts. A rotating block is rotatably provided at the end of the rotating plate. A linkage seat is rotatably provided between the two rotating blocks. A lifting cylinder is provided with the top plate of the base facing downwards. A push head is provided on the drive shaft of the lifting cylinder facing the linkage seat.

[0008] Furthermore, the upper plate of the upright is recessed upward to form a support part, and a slot is opened in the middle of the frame of the roller conveyor table, with the support part located inside the slot.

[0009] Furthermore, the chain drive mechanism includes a rotatably mounted shaft that passes laterally through all the uprights. A drive sprocket is rotatably mounted on the shaft, directly opposite each upright. Several rotating sprockets are rotatably mounted on each upright. The conveyor chain is fitted between the rotating sprockets and drive sprockets on the same upright plate. A chain drive motor for driving the shaft rotation is provided on the lifting plate.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0011] 1. Two roller conveyor tables are horizontally arranged on the machine base, which can simultaneously transport two seedling boxes. Compared with the traditional single-station device, the operating efficiency is greatly improved, meeting the production needs of large-scale seedling cultivation.

[0012] 2. The uprights on the lifting plate are located between two adjacent rollers on the left and right roller conveyor platforms. The conveyor chain on the uprights can smoothly lift the seedling boxes when they are lifted, and will not affect the normal conveying of the roller conveyor platform when they fall back. This effectively avoids interference between the conveying mechanism and the lifting mechanism and ensures the smoothness of the operation.

[0013] 3. The lifting drive mechanism, through the cooperation of a pair of linkage shafts, linkage plate, rotating plate, linkage seat and lifting cylinder, realizes the synchronous upward movement of four slide rods, which drives the lifting plate to lift smoothly, so that the seedling box is subjected to uniform force during the lifting process, avoiding tilting or tipping, and improving the stability and reliability of the lifting operation.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This embodiment of a dual-station seedling box conveying and lifting device includes a base 1. Two roller conveyor platforms 3 are horizontally arranged on the base 1. A lifting plate 4 is provided on the base 1. Several vertical supports 5 are longitudinally spaced on the lifting plate 4. Each vertical support 5 is located between two adjacent conveyor rollers on the two roller conveyor platforms 3. A conveyor chain 6 is rotatably mounted on each vertical support 5. A chain drive mechanism for driving the conveyor chain 6 to rotate synchronously is provided on the lifting plate 4. Sliding sleeves 7 are provided on the top plate of the base 1 at the four corners of the lifting plate 4. Sliding rods 8 are provided inside the sliding sleeves 7. The upper part of each sliding rod 8 is connected to the corresponding position of the lifting plate 4. A lifting drive mechanism for driving the four sliding rods 8 to move upward synchronously is provided below the base 1.

[0021] In this device, two roller conveyor platforms are horizontally arranged on the base, forming two conveying stations. Each conveying station can transport seedling boxes, improving the conveying efficiency of the seedling boxes. Since the roller conveyor platforms are not the focus of this device, they will not be described in detail here.

[0022] In this embodiment, multiple uprights are provided. Each upright is located between two adjacent rollers on the left and right roller conveyor tables. In the initial state, the height of the uprights is slightly lower than the conveying surface of the roller conveyor table.

[0023] Combination Figure 1 , Figure 4-5 Since the upper plate of the upright 5 is recessed upwards to form a support part 9, and the frame 2 of the roller conveyor table 3 has a slot 10 in the middle, the support part 9 is located in the slot 10. In the initial state, the support part is located in the slot at the same position, and the slot of the frame supports the entire upright through the support part, with the upright in the lowest position.

[0024] The lifting plate is equipped with a chain drive mechanism to drive all conveyor chains to rotate synchronously. Sliding sleeves are installed at the four corners of the lifting plate on the top plate of the machine base, and each sliding sleeve contains a sliding rod. The upper end of the sliding rod is fixedly connected to the corresponding corner of the lifting plate. A lifting drive mechanism is located below the machine base to synchronously drive the four sliding rods upwards, thereby lifting the lifting plate and the conveyor chains on the upright frame as a whole.

[0025] As a preferred structure, such as Figure 2 The lifting drive mechanism includes a pair of left and right linkage shafts 11 rotatably mounted. Both ends of the linkage shaft 11 are provided with linkage plates 12. The linkage plates 12 are rotatably connected to the lower part of the corresponding slide rod 8 through short blocks 13. A rotating plate 14 is provided in the middle of the linkage shaft 11. A rotating block 15 is rotatably provided at the end of the rotating plate 14. A linkage seat 16 is rotatably provided between the two rotating blocks 15. The top plate of the base 1 is provided with a lifting cylinder 17 facing downward. The drive shaft of the lifting cylinder 7 is provided with a push head 23 facing the linkage seat 16.

[0026] In this structure, the lifting drive mechanism includes a pair of parallel linkage shafts on the left and right sides. Linkage plates are fixedly installed at both ends of the linkage shafts, and the outer ends of the linkage plates are rotatably connected to the lower ends of the corresponding slide rods via short blocks. A rotating plate is fixedly installed in the middle of the linkage shafts, and a rotating block is rotatably connected to the end of the rotating plate. A linkage seat is rotatably installed between the two rotating blocks. A lifting cylinder is installed below the top plate of the base. When the drive shaft of the lifting cylinder extends downwards, it pushes the linkage seat downwards, causing the rotating plate to drive the linkage shaft to rotate inwards, thereby causing the linkage plate to push the four slide rods upwards synchronously, achieving a smooth lifting of the lifting plate.

[0027] As a specific structure, such as Figure 3-4 The chain drive mechanism includes a rotating shaft 19 that is rotatably mounted. The rotating shaft passes laterally through all the uprights 5. A drive sprocket 20 is rotatably mounted on the rotating shaft 19 facing each upright. Several rotating sprockets 21 are rotatably mounted on the uprights 5. The conveyor chain 6 is sleeved between the rotating sprockets 21 and the drive sprockets 20 on the same upright plate. A chain drive motor 22 for driving the rotating shaft is provided on the lifting plate.

[0028] In this embodiment, a chain drive motor is installed on the lifting plate. The chain drive motor drives the rotating shaft to rotate, thereby driving all the drive sprockets to rotate synchronously, so that each conveyor chain can achieve synchronous conveying operation.

[0029] The working principle of the above embodiment is as follows: the seedling box is transported to the corresponding roller conveyor platform through an external conveying device. The conveying rollers of the roller conveyor platform rotate to transport the seedling box to the designated position. At this time, the lifting plate is in the initial position, and the top surface of the conveying chain on the upright is lower than the conveying surface of the roller conveyor platform. The seedling box is supported by the roller conveyor platform.

[0030] Once the seedling box reaches the designated position, the lifting cylinder is activated, its drive shaft extends, and pushes the linkage seat downwards via the pusher head. The linkage seat drives the two rotating plates on the left and right to rotate, which in turn rotates the linkage shaft, causing the linkage plates at both ends to rotate. The linkage plates push the slide rods upwards through short blocks within the sliding sleeves, and the slide rods drive the lifting plate upwards. The conveyor chain on the upright frame rises accordingly, lifting the seedling box from the roller conveyor platform, thus achieving the lifting operation. During the lifting process, because the four slide rods rise synchronously, the lifting plate moves smoothly, and the seedling box is subjected to uniform force.

[0031] In the lifted state, the seedling box is longitudinally transported to the corresponding workstation. The chain drive motor is started, which drives the rotating shaft to rotate. The drive sprocket on the rotating shaft drives the conveyor chain to rotate synchronously. After the conveyor chain moves the seedling box longitudinally to the corresponding workstation, the drive motor stops.

[0032] After the lifting operation is completed, the drive shaft of the lifting cylinder retracts, and the jacking head no longer pushes the linkage seat. At the same time, under the gravity of the lifting plate and the seedling box, the slide bar slides downward, driving the linkage plate, rotating plate, and linkage seat to reset. The lifting plate returns to its initial position, and the top surface of the conveyor chain on the upright is lower than the conveying surface of the roller conveyor table. The roller conveyor table can then transport the seedling boxes normally.

[0033] The entire workflow is now complete, and anything not described in detail in this specification is existing technology known to those skilled in the art.
