Specific embodiments

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the attached drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0030] A ship unloader or a portal crane is a special unloading device used in bulk material terminals to lift the materials in the ship through the excavation of a grab bucket, and after multi-stage transfer, finally unload the materials onto the terminal belt conveyor.

[0031] For the feeding and conveying system therein, it is used to unload the materials in the cabin to the hopper via the grab bucket, and then convey them to the terminal belt conveyor through the hopper to realize the unloading of the materials from the ship. During this process, there are problems such as different characteristics of the unloaded materials, eccentric impact caused by the change of the falling height of the materials flowing through, and dust flying. To solve the above problems, improve the equipment use efficiency, and ensure the environmental protection operation of the ship unloading equipment, it is necessary to develop a feeding and conveying system with an environmentally friendly multi-stage material guiding device.

[0032] As Figures 1 to 7 shown, the embodiment of the present utility model discloses a feeding and conveying system with an environmentally friendly multi-stage material guiding device, which solves the problems of material spillage and dust raising during the material conveying process, and solves the problems such as belt deviation caused by the change of the landing point of the materials during the material conveying process due to the material characteristics, which affect the operation of the equipment, and ensures the more efficient and environmentally friendly operation of the ship unloading equipment.

[0033] Specifically, this embodiment includes a hopper feeding system 1, a sealed material guiding chute 2, a sealed material guiding skirt plate 3, a sealed head baffle centering chute 4, and a sealed plate type adjustable feeding device 5. The hopper feeding system 1 is installed on the gantry structure of the ship unloading equipment a to receive the materials grabbed by the grab bucket b from the cabin.

[0034] The top of the hopper feeding system is provided with a material inlet, the bottom of the hopper feeding system is a material outlet, the bottom of the hopper feeding system is connected to the upper end of the sealed material guiding chute, the lower end of the sealed material guiding chute is located on the sealed material guiding skirt plate, and the materials are transferred to the feeding conveyor c. The sealed head baffle centering chute is installed within the throwing range of the feeding conveyor, and the sealed plate type adjustable feeding device is installed below the sealed head baffle centering chute and above the terminal conveyor d.

[0035] The sealed material guiding skirt plate is arranged on both sides and above the feeding conveyor and is arranged throughout the whole length of the feeding conveyor to ensure sealing and play a role in guiding materials at the same time.

[0036] The sealed material guiding chute includes an upper trough body and a lower trough body. The cross-sections of the upper trough body and the lower trough body are both inverted trapezoids. The apex angle of the upper trough body is greater than the base angle of the lower trough body, and the center of the lower trough body is directly opposite to the upper part of the feeding conveyor. This setting form enables the materials to have a certain centering property during the flowing process, ensures the smooth flowing of the materials, greatly reduces the falling speed of the materials, prevents the impact on the feeding conveyor c, and at the same time, it is a closed space for conveying and reduces the phenomenon of dust flying.

[0037] The sealed material guide skirt includes a vertical plate, a horizontal plate and an inclined plate, which are connected to form a protective structure covering the feeding conveyor. The bottom surface of the inclined plate is located above the feeding conveyor, and the angle between the inclined plate and the horizontal plate in the covering area is an obtuse angle. This ensures that the material is always located within the conveyor belt surface during the conveying process, and no material spillage occurs.

[0038] During operation, a sealing cover is provided between the sealed material guide skirt and the sealed material guide chute to prevent dust from falling materials from escaping, thus ensuring that no dust is flying.

[0039] The sealed head baffle aligning chute includes a sealed chute 41, an aligning baffle 42 and an adjusting push rod 43. The sealed chute is arranged outside the throwing end of the feeding conveyor, and is connected to the sealed guide chute in front, and is connected to a sealed two-stage adjusting guide plate feeding device at the bottom. The aligning baffle is located inside the sealed chute. The upper end of the aligning baffle is hinged on the sealed chute, and an adjusting push rod is installed in the middle through a hinge shaft. The aligning baffle includes a main body connected to the adjusting push rod, and blocking parts are symmetrically arranged on both sides of the main body. There is a preset obtuse angle between the blocking part and the main body, and its shape is like a "C" shape, which can gather the materials thrown out by the feeding conveyor. By adjusting the extension and contraction of the push rod, the deflection angle of the aligning baffle can be adjusted, thereby adjusting the flow direction of the material flow in the downstream.

[0040] The sealed guide plate type adjustment feeding device includes a chute 51 and an adjustment guide plate 52. A sealed head baffle centering chute is connected above the chute, and the material is discharged at the bottom. Adjustment guide plates are arranged on both sides of the chute. The angle of the adjustment guide plates is adjustable and is used to further center the falling materials and drop them to the center position of the terminal conveyor.

[0041] By means of the above-mentioned self-aligning baffle and adjusting guide plate, the material can be accurately adjusted so that its landing point is aligned with the center of the terminal conveyor, without any eccentric load impact, ensuring that the terminal conveyor will not deviate during operation.

[0042] The sealed guide plate type adjustable feeding device also includes a skirt plate 53, the bottom surface height of the skirt plate is lower than the bottom surface height of the adjustable guide plate, and the skirt plate is installed on both sides of the chute to shape the material on the dock conveyor, thereby ensuring a stable shape in the initial stage of material transportation and preventing spillage.

[0043] The position of the matching adjustment guide plate on the chute is provided with a pin hole, and the connection between the adjustment guide plate and the preset pin hole is completed through the pin. The angle of the adjustment guide plate is changed to a certain extent. By adjusting the guide plate, the direction of the material flow can be changed, so that the material landing point is located at the center of the terminal conveyor as much as possible, preventing the terminal belt from running off.

[0044] The working principle of the utility model is as follows:

[0045] 1. The receiving grab b grabs materials from the cabin and unloads them into the hopper feeding system 1.

[0046] 2. The materials in the hopper feeding system 1 are conveyed to the feeding conveyor c through the sealed material guiding chute 2.

[0047] 3. The sealed material guiding skirt plate 3 arranged along the whole length of the feeding conveyor c can ensure sealing and play a role in guiding materials at the same time, enabling the continuous and stable conveyance of materials.

[0048] 4. The materials are gathered and centered by the centering baffle 42 in the centering chute 4 of the sealed head baffle, which throws the materials from the feeding conveyor c.

[0049] 5. The sealed guide plate type feeding adjusting device 5 adjusts the material flow direction again through the adjusting guide plate 52, so that the material landing point is as close as possible to the center position of the dock conveyor d, preventing the deviation of the dock belt.

[0050] After the implementation of the feeding and conveying system with an environment-friendly multi-stage material guiding device disclosed by the present utility model, during the material conveying process, a fully enclosed conveying method is adopted to complete the continuous transfer and transportation of materials. And on the material conveying line, according to the material transfer points and flow characteristics, various types of material guiding devices are arranged to achieve the fully enclosed and environment-friendly conveying of materials, ensuring that there is no material spillage, reducing equipment wear and tear, and ensuring the safe, efficient and environment-friendly operation of the equipment.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
