[0002] During the production and cultivation process of Tremella fuciformis, the empty culture bottles are placed and fixed in the tray, and then filled with culture medium. After the culture medium is filled and the culture bottles are capped, the tray needs to be transferred to the positioning conveyor trolley and stacked, and finally moved to the culture room for cultivation by the fixed conveyor trolley.

[0003] Existing devices for shifting, stacking, or unloading pallets are often complex in structure. The clamping mechanism rises and falls along with the movable base, requiring a high power source for the clamping mechanism. For example, utility model patent CN2022231725869 discloses a Tremella culture tray unstacking device in which a lifting beam rises and falls together with the movable base, and the number of pallets that can be moved at any one time is small. Furthermore, existing pallet shifting devices do not maintain proper positioning during movement, causing the clamping mechanism to wobble, which can easily cause the pallets to detach.

[0026] In this embodiment, guide rails 11 are provided on the front and rear sides of the top of the support mast. Axles 21 are rotatably connected to each side of the movable base. Rollers 22 that mate with the guide rails are fixed to the front and rear ends of the shafts. A first motor 23 is mounted on the movable base, and its output drives one of the shafts via a transmission chain. Limit switches 24 are located at each end of the guide rails. When the rollers contact the limit switches, the movable base stops moving, and the lifting mechanism begins its lifting motion.

[0027] In another embodiment, a gear may be installed at the output end of the first motor, the movable base and the guide rail are slidably matched, and a rack meshing with the gear is provided on the guide rail, thereby realizing the movement of the movable base through the gear rack mechanism.

[0028] In this embodiment, the lifting mechanism comprises a pair of longitudinal reels 31 mounted side by side in a transverse direction on a movable base. Each of the longitudinal reels is wound with a lifting belt 32 and is driven by a drive mechanism for synchronous rotation. Guide rods 33 are longitudinally fixed to either side of the movable base. The pair of lifting belts are respectively wound around corresponding guide rods and fixedly connected to the lifting frame at their lower ends. The lifting frame is raised and lowered by the winding of the longitudinal reels.

[0029] In this embodiment, to drive the longitudinal drums to rotate synchronously and in opposite directions, the drive mechanism includes a second motor 34 mounted on a movable base. The output shaft of the second motor meshes with a first driven gear 36 on one of the longitudinal drums via a driving gear 35. The driving gear, in turn, meshes with a second driven gear 38 on the other longitudinal drum via a transition gear 37. The driving gear and the transition gear have the same number of teeth, and the first and second driven gears have the same number of teeth, thereby ensuring synchronous rotation of the two longitudinal drums in opposite directions at the same speed.

[0030] In this embodiment, to better connect the lifting belt to the lifting frame, two fixing plates 40 are installed on either side of the top of the lifting frame. The lower end of the lifting belt is fixed to the fixing plates via bolts 41 spaced longitudinally. The lifting belt can be a rollable belt such as a nylon belt.

[0031] In this embodiment, in order to clamp the pallet and move it with the moving seat, the clamping mechanism includes a pair of cross bars 51 fixed to the bottom surface of the lifting frame at longitudinal intervals, and two pairs of longitudinally arranged clamping plates 52 are slidably connected to the pair of cross bars. A double-headed cylinder 53 is laterally installed on the bottom surface of the lifting frame and on the upper side of each pair of clamping plates. The two ends of the double-headed cylinder are respectively connected to the corresponding clamping plates, so that the double-headed cylinder drives a pair of clamping plates to move toward or away from each other, thereby clamping the pallet or separating from the pallet.

[0032] In this embodiment, the upper end of the splint is slidably connected to the crossbar via a slider 54. In order to prevent the tray from detaching from the splint, the lower end of the splint is provided with an inwardly bent edge 521, which hooks the flange of the support plate to prevent the tray from detaching from the splint during movement.

[0033] In this embodiment, the movable base comprises two front and rear horizontal plates, secured together by multiple rods. To prevent the movable base from wobbling while carrying the tray, a positioning structure comprises vertical positioning slots 25 on the front and rear horizontal plates of the movable base. The front and rear portions of the lifting frame are each mounted with a fixed base 60, each equipped with a pair of vertical plates 61. A pair of longitudinally arranged positioning pins 62 are positioned between the vertical plates, allowing the positioning pins to engage with the positioning slots when the lifting frame is raised, thereby maintaining the position of the lifting frame.

[0034] In this embodiment, the pallet input mechanism may include a longitudinally arranged conveyor roller mechanism comprising a plurality of longitudinally spaced transverse rollers 101. A placement platform 104 is provided on the side of the conveyor roller mechanism located in the lower section of the support gantry and adjacent to the pallet storage vehicle positioning platform. A conveyor chain 102 is transversely arranged between two adjacent transverse rollers in the lower section of the support gantry. Push blocks 103 are fixed to the conveyor chains at intervals. Three conveyor chains form a group and are driven to rotate by the same drive shaft, so that the conveyor chains in the same group rotate synchronously to move the pallets on the conveyor roller mechanism to the placement platform. At least two groups of conveyor chains are provided to form two rows of pallets in the lower section of the support gantry, with at least two pallets in each row. A clamping mechanism can clamp at least four pallets at a time and move them to the positioning vehicle.

[0035] A limit plate 105 is provided at the front end of the conveying roller mechanism, and a sensor 106 electrically connected to the power source of the conveyor chain through a controller is provided on the side of the placement platform close to the pallet storage vehicle positioning platform, so that the conveyor chain rotates and the push block pushes the pallet to move horizontally. After the sensor detects the pallet, the conveyor chain stops rotating.

[0036] In this embodiment, the pallet storage vehicle positioning platform includes a protective steel plate 201 fixed to the ground, and a positioning frame 202 for four positioning vehicles 210 is provided at the rear end of the steel protective plate to park and position four positioning vehicles; the rear side of the positioning frame is provided with a magnetic block 203 that cooperates with the positioning vehicle, so that the positioning vehicle can be adsorbed by the magnetic block and cooperated with the positioning frame to position the positioning vehicle, thereby preventing the positioning vehicle from moving.

[0037] The culture bottle trays loaded with Tremella fuciformis culture medium are delivered to the lower side of the support gantry by a conveyor roller mechanism, and then the trays are moved to the placement table by a conveyor chain, so that two rows of trays can be formed on the lower side of the support gantry, with at least two trays in each row. After the pallet storage cart is positioned and fully parked on the positioning table, the lifting frame descends and clamps the trays. The lifting frame rises and aligns with the mobile seat. The mobile seat moves horizontally above the positioning cart and descends to stack the trays on the positioning cart. Each pair stacks two positioning carts simultaneously. The controller controls the height of the lifting frame each time it is lowered from the positioning cart to achieve multi-layer tray stacking, and controls the number of trays stacked on each positioning cart.
