Description

Technical Field

[0001] This utility model relates to the field of poultry transportation and unloading technology, specifically to a duck unloading device. Background Technology

[0002] After being caged at the farm, live ducks are usually transported to the slaughterhouse via fenced transport vehicles. There, they are unloaded at the docking platform, where workers manually drag and unload the ducks one by one from the truck bed. They are then transferred to the next process using other tools. The handling process is slow, time-consuming, and labor-intensive, and the unloading efficiency is low, resulting in long waiting times for transport vehicles.

[0003] Therefore, how to solve the above-mentioned technical problems has become the subject of this utility model. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a duck unloading device for duck carts that can quickly unload duck baskets from inside the cart.

[0007] The carriage includes a horizontally arranged floor plate, and a vertical front plate is fixedly connected to the top of the floor plate near the driver's cab. The floor plate is symmetrically arranged with fence-like side plates on the left and right sides, and two doors are symmetrically arranged on the side of the two side plates away from the front plate.

[0008] A vertically arranged push plate is fixedly connected to the top of the unloading tray near the front plate. Several reinforcing plates are provided on the back side of the push plate. Several rollers that roll in cooperation with the bottom plate and the unloading platform are arranged sequentially at the bottom of the unloading tray. Several first guardrails are symmetrically arranged horizontally on both sides of the top of the unloading tray. One end of the first guardrail is fixedly connected to the push plate, and the other end is fixedly connected to a first fixing rod. The first fixing rod is fixedly connected to the top of the unloading tray on the side away from the push plate.

[0009] The displacement component includes a connecting block arranged along its length at the center of the bottom of the unloading tray. A threaded hole is provided on the inner side of the connecting block, and a threaded rod is threadedly connected to the threaded hole. The end of the threaded rod near the front plate passes through the front plate and is rotatably connected to the front plate. A worm gear is coaxially sleeved on the outer side of the end of the threaded rod. The worm gear meshes with a worm that is vertically arranged and rotatably connected to the outside of the carriage. The top end of the worm is coaxially fixedly connected to the output end of the displacement motor. The displacement motor is mounted on a fixed frame on the top of the carriage.

[0010] The two side plates are symmetrically provided with guide grooves on their lower sides, and the unloading tray is symmetrically provided with guide grooves on both sides.

[0011] The guide bar is a slidingly fitted guide groove.

[0012] The bottom sides of the limiting plate are provided with sliding strips, and the top sides of the unloading tray are symmetrically provided with sliding grooves that slide in cooperation with the sliding strips.

[0013] The limiting plate has several fixing holes symmetrically arranged on both sides. The side plate end has a connecting hole corresponding to each fixing hole. A limiting rod is threadedly connected between the fixing hole and the connecting hole.

[0014] The top pressing component includes a plurality of cylinder frames provided on the limiting plate, each cylinder frame having a cylinder horizontally mounted thereon, and the telescopic end of each cylinder being fixedly connected to the side wall of the top plate.

[0015] An electromagnet is provided on the side wall of the center of the push plate, and a metal plate is provided on the side wall of the limiting plate to magnetically engage with the electromagnet.

[0016] Several second guardrails are symmetrically and horizontally arranged on both sides of the top plate of the loading pallet. A fixing plate is fixedly connected to the top of the side of the loading pallet away from the carriage. Second fixing rods are symmetrically arranged on the side of the loading pallet close to the carriage. The two ends of the second guardrails are fixedly connected to the fixing plate and the second guardrail respectively.

[0017] The loading pallet has symmetrical movable plates on both sides of its bottom, and the unloading platform has movable grooves that slide with the movable plates.

[0018] The side wall of the fixing plate is provided with a fixing seat, and the fixing seat is fixedly connected to the traction end of the traction rope.

[0019] A plurality of U-shaped connecting plates are provided between the first fixing rod and the second fixing rod located on the same side. Two pins are symmetrically slidably inserted on both sides of each connecting plate. The first fixing rod and the second fixing rod are provided with insertion holes corresponding to the pins for insertion and engagement.

[0020] A battery and a hydraulic oil tank are respectively installed on the outside of the carriage, and a control terminal is installed in the driver's cab. The control terminal includes control components for the displacement component and control components for the top pressing component.

[0021] In practical use, this invention works as follows: When a cart loaded with duck baskets is transported, the push plate is close to the front plate. Under the magnetic attraction of the metal plate and the electromagnet, the limiting plate is pressed tightly against the push plate. Upon reaching the unloading platform at the slaughterhouse, the rear of the cart is close to the front of the unloading platform for easy rearward movement. The locked door is then opened to both sides. The displacement motor is started via the control terminal, and the worm gear drives the worm wheel, which in turn drives the threaded rod to rotate, thus pushing the unloading pallet towards one side of the unloading platform. Rollers ensure smooth movement on the unloading platform. When the limiting plate reaches the rear of the cart, it stops moving, and the cart and the limiting plate are fixedly connected by the limiting rod, thus limiting the position of the limiting plate within the cart. Simultaneously, the electromagnet is de-energized, releasing the magnetic attraction. Then, the loading pallet and the unloading pallet are aligned, ensuring the pallet is level. After the loading and unloading pallets are bound together using connecting plates, pins, and sockets, the displacement motor is activated to rotate and slowly retract the unloading pallet, moving it to one side of the truck bed. The electric winch releases sufficient traction rope, and under the action of the limit plate and top plate, all the stacked duck crates are gradually pushed onto the top surface of the transfer pallet. Once the unloading pallet is fully reset, the hydraulic cylinder is activated, and the top plate further pushes the duck crates onto one side of the loading pallet. Then, the locking state of the limit plate is released, and it is manually pushed to one side of the push plate. The electromagnet is energized to re-magnetically attract the limit plate, making it fit tightly against it to ensure space for re-transfer. The duck truck can then leave, and the electric winch retracts the traction rope, pulling the loading pallet away from the edge of the unloading platform before transferring the duck crates to the next process.

[0022] It should also be noted that the duck-shaped unloading vehicle connects to a power take-off (PTO), hydraulic pump, hydraulic lines, and other hydraulic system components via its chassis, which in turn connect to the hydraulic cylinders. The control unit for the top pressing component is an electromagnetic directional valve that controls the extension and retraction of the hydraulic cylinders. This electromagnetic directional valve is powered by the vehicle's battery. The control unit for the displacement component controls the forward and reverse rotation of the displacement motor, enabling automatic control of the unloading pallet to move forward and backward to a predetermined position. The battery provides power to the displacement motor.

[0023] Furthermore, a stepped unloading platform can be built to meet the overall unloading needs of duck carts of different specifications, and the specifications of related components can be adjusted accordingly.

[0024] The beneficial effects of this utility model are: it can move and unload the entire truckload of duck baskets as a whole, significantly improving unloading efficiency, requiring less manual intervention, and greatly reducing the labor intensity of operators during the unloading process of duck baskets.

[0042] In actual use: When a cart loaded with duck baskets is transported, the push plate 201 is close to the front plate 102. Under the magnetic attraction of the metal plate 304 and the electromagnet 208, the limit plate 3 is tightly attached to the push plate 201. The electromagnet 208 is powered by the battery 14. The control terminal is equipped with a switch to control the on / off state of the electromagnet 208. After arriving at the unloading platform 5 of the slaughterhouse, the rear of the cart 1 is close to the front of the unloading platform 5 for easy rearward movement. The locked door 104 is then opened to both sides via the control... The terminal starts the displacement motor 706, the worm gear 705 drives the worm wheel 704, and the worm wheel 704 drives the threaded rod 703 to rotate, thereby pushing the unloading pallet 2 towards one side of the unloading platform 5.

The loading pallet 6 and unloading pallet 2 are then bound together using connecting plate 11, pins 12, and insertion holes 13. The displacement motor 706 is then activated to rotate and slowly retract the unloading pallet 2, moving it towards one side of the truck bed. The electric winch 10 releases sufficient traction rope 9. Under the action of the limiting plate 3 and top plate 4, all the stacked duck crates are gradually pushed onto the top surface of the transfer pallet 2. Once the unloading pallet 2 is fully reset, the hydraulic cylinder 802 is activated, and the top plate 4 further pushes the duck crates into one side of the loading pallet 2. The locking state of the limiting plate 3 is then released, and it is manually pushed towards the push plate 201. The electromagnet 208 is energized to re-magnetically attract the limiting plate 3, ensuring a tight fit and sufficient space for re-transfer. The duck truck can then leave. The electric winch 10 retracts the traction rope 9, pulling the loading pallet 6 away from the edge of the unloading platform 5, and the duck crates are then transferred to the next process.

[0043] It should also be noted that the duck-shaped unloading vehicle connects to the power take-off, hydraulic pump, hydraulic pipes, and other hydraulic system components via its chassis, which in turn connect to the hydraulic cylinder 802. The control unit for the pressing component 8 is an electromagnetic directional valve that controls the extension and retraction of the hydraulic cylinder 802. The electromagnetic directional valve is powered by the vehicle's battery. The control unit for the displacement component controls the forward and reverse rotation of the displacement motor 706, enabling automatic control of the unloading tray 2 to move forward and backward to a predetermined position.
