Description

Technical Field

[0001] The utility model relates to the technical field of transfer equipment, in particular to a feeding vehicle used for transferring powdered materials. Background Art

[0002] The welding rod consists of an internal welding core and an external coating. The function of the coating is to meet the needs of welding, so as to ensure that the deposited metal has certain chemical composition and properties. The welding rod coating is made of oxides, carbonates, silicates, organic matter, fluorides, ferroalloys and other chemical powders, mixed in a certain formula ratio. After various raw materials are mixed to form a powder, it is necessary to transfer the evenly mixed powder in the mixing box to the shaping mold, and after mixing with water glass, it is die-cast on the outside of the welding core through the shaping mold.

[0003] At present, in the prior art, the material transfer from the mixing box to the shaping mold attachment generally relies on manual loading and unloading. For example, workers use bags to pack the materials discharged from the mixing box, and then place the multi-piece materials on a cart. Then the workers push the cart to the vicinity of the shaping mold and pour the powder in the bag into the feeding port of the shaping mold. This type of transfer method greatly relies on manual loading and unloading, and continuous production requires a high labor intensity for workers.

[0004] Therefore, the prior art needs to be improved. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the existing technology relies on manual loading and unloading, which has a high labor intensity. The purpose is to provide a feeding vehicle for powder material transportation, which adopts corresponding technical means and has the beneficial effects of easy loading and unloading and low labor intensity.

[0006] The utility model is realized by the following technical solutions:

[0008] In the above technical scheme, the feeding vehicle for powder material transportation can be pushed by workers, or it can be remotely controlled and automatically operated by automation and intelligent recognition technology. The feeding vehicle for powder material transportation relies on the walking mechanism to run to the bottom of the mixing box outlet, so that the receiving hopper is aligned with the mixing box outlet above. The gate valve is controlled to be closed, and the mixing box starts to be loaded. After the receiving hopper is filled with powder, the feeding vehicle for powder material transportation is moved to the front of the shaping mold through the walking mechanism, so that the inlet of the shaping mold is aligned with the docking head. Then the telescopic drive member drives the docking head to descend, and the docking head and the inlet of the shaping mold below are sealed and docked. Finally, the gate valve is controlled to open, and the powder in the receiving hopper automatically falls into the docking head, and then falls into the inlet of the shaping mold below. The arch breaking mechanism works to shake off all the powder on the inner wall of the receiving hopper, reducing the residual powder in the receiving hopper, thereby reducing waste.

[0009] Furthermore, in the utility model, the telescopic driving member is configured as an electrically controlled hydraulic rod, the frame is provided with a through hole for the docking head to pass downward, and the bottom end of the telescopic driving member is connected to the flange of the docking head.

[0010] Furthermore, in the utility model, a sealing sponge is provided at the port of the docking joint.

[0011] Furthermore, in the utility model, the flange of the docking joint is provided with a guide rod, and the frame is provided with a vertical hole for the guide rod to pass through.

[0012] Furthermore, in the utility model, the arch-breaking mechanism comprises an air hammer and a mounting bracket connected to each other, the mounting bracket is connected to the vehicle frame, and the air hammer is connected to the outer wall of the material receiving hopper.

[0013] Furthermore, in the utility model, the frame is provided with a weighing device, the weighing device is connected to a supporting frame, and the supporting frame is connected to the receiving hopper.

[0014] Furthermore, in the present invention, the walking mechanism includes wheels and a driving motor, the wheels are arranged at the bottom of the frame, and the driving motor is drivingly connected to the wheels.

[0015] Furthermore, in the present invention, the wheels are configured as metal wheels.

[0016] Furthermore, in the utility model, the frame is provided with a control box, and the control box is electrically connected to the telescopic drive member, the arch breaking mechanism and the walking mechanism.

[0017] Furthermore, in the present invention, the flexible tube is configured as a cylindrical cloth bag.

[0018] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0019] 1. Save labor: When loading, the feeding vehicle used for powder material transportation relies on the walking mechanism to run to the bottom of the mixing box outlet, and then controls the gate valve to close, and the mixing box starts to load. When unloading, the feeding vehicle filled with powder for powder material transportation moves in front of the shaping mold, so that the inlet of the shaping mold is aligned with the butt joint. Then the telescopic drive member drives the butt joint to descend, and the butt joint and the inlet of the shaping mold below are sealed and docked. Finally, the gate valve is controlled to open, and the powder in the receiving hopper automatically falls into the butt joint, and then falls into the inlet of the shaping mold below. No manpower is required for loading and unloading, which reduces labor intensity.

[0020] 2. Reduce waste: Since the joint and the inlet of the forming mold below are sealed during unloading, there will be no leakage during unloading. At the same time, the arch breaking mechanism will shake off all the powder on the inner wall of the hopper to reduce the residual powder in the hopper. Reducing the waste of powder saves manufacturing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Example

[0027] This embodiment provides a feeding vehicle for transferring powder materials, such as Figure 1 As shown, the specific structure is described as follows.

[0028] Please refer to Figure 1 As shown, the feeding vehicle for powder material transportation of the present embodiment is mainly composed of five parts: a vehicle frame 1, a traveling mechanism 2, a material receiving mechanism 3, a discharge mechanism 4 and an arch breaking mechanism 5. The vehicle frame 1 is used to provide an installation platform for other components, the traveling mechanism 2 is used to facilitate the movement of the feeding vehicle for powder material transportation, the material receiving mechanism 3 is used to receive the powder poured out of the mixing box, the discharge mechanism 4 is used to pour the powder into the feeding port of the shaping mold, and the arch breaking mechanism 5 is used to reduce the residual powder in the receiving hopper 301.

[0029] Further, combined with Figure 1 As shown, the frame 1 is a base made of a metal plate, and the walking mechanism 2 includes four wheels 201 and a drive motor 202. The four wheels 201 are installed at the four corners of the bottom of the frame 1, and the drive motor 202 is installed on the top of the frame 1. The wheels 201 and the drive motor 202 realize power transmission through gears. The wheels 201 are metal wheels, which have the advantages of higher load capacity and longer service life.

[0030] It should be noted that, in order to facilitate the movement and steering of the frame 1, a handrail can be welded on the frame 1, and the worker can push and move it manually. In other embodiments, the frame 1 and the walking mechanism 2 can directly adopt the AGV automatic transport vehicle in the prior art, which deeply integrates automation technology and intelligent recognition technology. In the remote control state or the automatic driving state, it can realize translation, rotation, translation and rotation in any direction in the plane, realize unmanned transportation, and further reduce labor.

[0031] In some implementations of this embodiment, Figure 1As shown, the material receiving mechanism 3 includes a receiving hopper 301 and a support frame 302. The receiving hopper 301 is a bucket-shaped chamber made of metal, and the support frame 302 is a metal bracket. The support frame 302 includes a metal plate sleeved on the bottom of the receiving hopper 301, and four vertical metal plates are installed on the top of the support frame 302. The support frame 302 and the outer wall of the receiving hopper 301 are welded and fixed.

[0032] Further, such as Figure 1 As shown, a weighing device 6 is installed on the top right side of the frame 1, and the bottom of the support frame 302 is fixedly connected to the weighing device 6, so the weighing device 6 can calculate the loading amount of the powder, which helps to determine whether the receiving hopper 301 is full through non-contact.

[0033] Furthermore, the top of the receiving hopper 301 is a larger diameter expansion port, which is convenient for accurately receiving the powder poured out of the mixing box. The bottom of the receiving hopper 301 is a smaller diameter contraction port (i.e., bottom opening), which is convenient for feeding into the feeding port of the shaping mold. An electrically controlled gate valve is installed at the bottom opening of the receiving hopper 301, such as a pneumatic gate valve in the prior art. When the bottom opening needs to be closed, the gate valve is controlled to be closed, and when the bottom opening needs to be opened, the gate valve is controlled to be opened.

[0034] Combination Figure 1 As shown, the unloading mechanism 4 includes three parts: a flexible tube 401, a butt joint 402, and a telescopic driving member 403. The flexible tube 401 is a cylindrical cloth bag that can be telescopic. The top of the flexible tube 401 covers the bottom opening of the receiving hopper 301, and the butt joint 402 is a sleeve with a flange. The bottom end of the flexible tube 401 covers the top end of the butt joint 402. A sealing sponge is installed at the port of the butt joint 402. After the butt joint 402 and the feed port of the shaping mold are fitted and docked, the sealing sponge is squeezed to reduce the gap between them, thereby reducing powder leakage and waste.

[0035] Further, such as Figure 1 As shown, a through hole is provided in the vehicle frame 1, and the docking joint 402 can extend from the through hole. The telescopic driving member 403 adopts a hydraulic push rod in the prior art, and two are installed at the bottom of the vehicle frame 1, and are symmetrically located on both sides of the docking joint 402. The bottom end of the telescopic driving member 403 is fixedly connected to the flange of the docking joint 402. The two telescopic driving members 403 are synchronously extended and retracted, thereby controlling the docking joint 402 to descend and ascend, and realize docking and separation.

[0036] It should be noted that, in order to correct the up and down movement direction of the butt joint 402, two vertical guide rods 404 are welded on the top of the flange of the butt joint 402, and the two guide rods 404 are symmetrical. A vertical hole is opened in the frame 1, and the guide rod 404 passes through the vertical hole and can move up and down along the vertical hole.

[0037] In some implementations of this embodiment, the arch breaking mechanism 5 includes two parts: an air hammer 501 and a mounting bracket 502. The mounting bracket 502 is a frame composed of profiles and is fixedly mounted on the left top of the frame 1. The air hammer 501 is fixedly connected to the mounting bracket 502, and the air hammer 501 is also fixedly connected to the outer wall of the receiving hopper 301. After the air hammer 501 is started, it can drive the receiving hopper 301 to vibrate, thereby shaking off the powder adhering to the inner wall of the receiving hopper 301, reducing waste.

[0038] In some implementations of this embodiment, a control box 7 can be used to control the operation of each electrical component. A PLC control is installed inside the control box 7, and the PLC control and the air hammer 501, the weighing device 6, the drive motor 202, and the telescopic drive member 403 are connected by wires to control the operation. It should be noted that the electronic components such as the PLC, the air hammer 501, the weighing device 6, the drive motor 202 in this embodiment are all standard parts or parts known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods. When the components are assembled, all electrical components are connected by wires.

[0039] The working principle of the feeding vehicle for powder material transportation of the utility model is as follows:

[0040] During loading, the feeding vehicle used for powder material transportation relies on the walking mechanism 2 to run to the right below the discharge port of the mixing box, and then controls the gate valve to close, and the mixing box starts to load. During unloading, the feeding vehicle for powder material transportation filled with powder moves in front of the shaping mold, so that the feeding port of the shaping mold is aligned with the docking head 402. Then the telescopic drive member 403 drives the docking head 402 to descend, and the docking head 402 and the feeding port of the shaping mold below are sealed and docked. Finally, the gate valve is controlled to open, and the powder in the receiving hopper 301 automatically falls into the docking head 402, and then falls into the feeding port of the shaping mold below. No manpower is required for loading and unloading, which reduces the labor intensity. Since the docking head 402 and the feeding port of the shaping mold below are sealed and docked during unloading, there will be no leakage during the unloading process. At the same time, the arch breaking mechanism 5 works to shake off all the powder on the inner wall of the receiving hopper 301, reducing the residual powder in the receiving hopper 301. Reduce the waste of powder and save manufacturing costs
