Description

Technical Field

[0001] The utility model relates to the technical field of ship unloaders, in particular to a blanking chute structure and a ship unloader. Background Art

[0002] In the prior art, a ship unloader is generally used to conveniently load particulate materials such as sand and gravel onto a ship. The ship unloader includes a main body part located on the shore and a conveying arm connected to the main body part. The end of the conveying arm is the blanking end. Generally, a conveyor belt is also arranged in the conveying arm to convey materials (i.e., sand and gravel), and then the materials fall into the bunker of the ship through the blanking end to complete the loading. In the actual loading process, there is generally a certain height between the blanking end and the bunker. A large amount of dust will be stirred up during the falling process of the materials, resulting in environmental pollution around and also material loss. In order to avoid dust pollution and material loss, in the prior art, a channel is generally connected below the blanking end so that the materials fall into the bunker through the channel, which can reduce the occurrence of dust pollution and material loss. However, the channel generally uses a plastic pipe with a fixed length. During the loading process, as the materials gradually increase, the height will become higher. Therefore, in order to ensure the smooth completion of material loading, the lower end of the channel needs to be above the highest point of the materials (the height of the materials after loading completion can be predicted, above this predicted height), which still causes dust to be stirred up during the loading process. Summary of the Utility Model

[0003] Aiming at the deficiencies in the prior art, the utility model provides a blanking chute structure, which solves the problem that in the prior art, the lower end of the channel needs to be above the highest point of the materials, resulting in dust being stirred up during the loading process.

[0004] According to an embodiment of the utility model, a blanking chute structure includes:

[0005] A pair of elevators, the two elevators are arranged oppositely and are respectively connected with rotating wheels through suspension ropes;

[0006] A feeding hopper, the two elevators are respectively fixedly installed on the feeding hopper;

[0007] A blanking cover, the two rotating wheels are respectively rotatably installed on the blanking cover;

[0008] A plurality of chutes, all the chutes are arranged in an overlapping manner in sequence and are located between the lower open end of the feeding hopper and the upper open end of the blanking cover;

[0009] The lower end of the feeding hopper is also fixedly connected with a first guide tube extending into the uppermost chute, and the lower end of the lowermost chute extends into the blanking cover.

[0010] In the above embodiments, the relative distance between the feeding hopper and the discharging cover is changed by the lifter, and the chute between the two plays a connecting role, forming a channel similar to that in the prior art as a whole. The difference is that the lower end of the discharging cover in this solution can continuously contact the material below, thereby preventing the material from stirring up dust, solving the problem in the prior art that the lower end of the channel needs to be above the highest point of the material, which causes dust to be stirred up during the loading process.

[0011] Further, the discharging cover includes a vertical cylinder section located above and an open section located below. Lower mounting frames are respectively fixedly connected to both sides of the vertical cylinder section, and two rotating wheels are respectively mounted on the two lower mounting frames. The chute at the lowermost layer extends into the vertical cylinder section.

[0012] Further, a second material guiding cylinder is also fixedly connected inside the vertical cylinder section, and the chute at the lowermost layer extends into the second material guiding cylinder, and the lower end of the second material guiding cylinder extends into the open section.

[0013] Further, upper mounting frames are respectively fixedly connected to both sides of the feeding hopper, and two lifters are respectively mounted on the two upper mounting frames.

[0014] Further, both sides of all the chutes are connected in series by connecting cables so that they are connected end to end with each other.

[0015] Further, a discharging hopper is also provided at the lower end of the second material guiding cylinder.

[0016] Further, the lifter includes a winch.

[0017] According to the embodiment, a ship unloader is also provided, which includes a conveying arm with a discharging end provided at one end. Fixing hooks are fixedly connected to both sides of the conveying arm. The discharging chute structure as described above is also included, wherein the two opposite sides of the feeding hopper are respectively rotatably arranged on the corresponding two fixing hooks through mounting shafts, and the discharging end is located directly above the feeding hopper.

[0018] Further, the fixing hooks are in an inclined U-shaped structure, and fixing ear plates arranged up and down are also fixedly connected to the opposite sides of the two fixing hooks, and the two fixing ear plates on the same fixing hook are connected by a pin shaft.

[0019] Compared with the prior art, the present utility model has the following beneficial effects:

[0020] By adjusting the height position of the discharging cover through the lifter, the relative distance between the feeding hopper and the discharging cover is changed, and the chute between the two plays a connecting role, forming a channel similar to that in the prior art as a whole. The difference is that the lower end of the discharging cover in this solution can continuously contact the material below, thereby preventing the material from stirring up dust, solving the problem in the prior art that the lower end of the channel needs to be above the highest point of the material, which causes dust to be stirred up during the loading process.

[0021] Meanwhile, a ship loader is provided. The ship loader can be used for hanging the feeding hopper of the chute structure through the fixed hooks arranged on the conveying arm. Both sides of the discharging hopper are supported in the fixed hooks through the mounting shafts, and the mounting shafts and the fixed hooks can rotate relative to each other. In this way, during the operation of the ship loader, even if the conveying arm pitches up and down, the discharging hopper can remain in a hanging state under its own weight and the weight of the structure below, that is, all the chutes are always in a vertical state, ensuring the smooth progress of the discharging process;

[0022] In this solution, the feeding hopper is rotationally supported on the fixed hook through the mounting shaft. At the same time, the feeding hopper together with other structures can also be removed by an external hoisting device as long as the mounting shafts on both sides are disengaged from the fixed hooks, which is convenient for disassembly and installation and very convenient for maintenance;

[0023] The discharging chute structure in this solution can be easily removed, so it can be removed and not used when loading some materials that do not require dust prevention, such as sand and gravel with high water content, which will not generate dust during the falling process, thus avoiding the impact wear of these materials on the inner wall of the chute and increasing the service life.

[0028] The technical solutions in the present invention will be further described below with reference to the drawings and embodiments.

[0029] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0030] In an exemplary embodiment, as Figure 1 , 2 shown, this embodiment provides a blanking chute structure, which includes:

[0031] A pair of elevators 1, the two elevators 1 are opposed to each other and are respectively connected with rotating wheels 2 through suspension ropes 20;

[0032] The feeding hopper 3, the two elevators 1 are respectively fixedly installed on the feeding hopper 3;

[0033] The blanking cover 4, the two rotating wheels 2 are respectively rotatably installed on the blanking cover 4;

[0034] A plurality of chutes 5, all the chutes 5 are arranged in an overlapping manner in sequence and are located between the lower open end of the feeding hopper 3 and the upper open end of the blanking cover 4;

[0035] The lower end of the feeding hopper 3 is also fixedly connected with a first guiding cylinder 6 extending into the uppermost chute 5, and the lower end of the lowermost chute 5 extends into the blanking cover 4.

[0036] In the above embodiment, the relative distance between the feeding hopper 3 and the blanking cover 4 is changed by the elevator 1, and the chute 5 between the two plays a connecting role, forming a channel similar to that in the prior art as a whole. The difference is that the lower end of the blanking cover 4 in this solution can continuously contact the material below, thereby preventing the material from stirring up dust, and solving the problem that the lower end of the channel in the prior art needs to be above the highest level of the material, which causes dust to be stirred up during the loading process.

[0037] As Figure 1 , 2As shown, in an exemplary embodiment of another aspect, the present blanking chute structure can be detachably installed on the ship loader, that is, a ship loader including the present blanking chute structure is also provided. The ship loader is similar to those in the prior art and includes a conveying arm 8 with a blanking end 9 provided at one end. Fixed hooks 10 are fixedly connected to both sides of the conveying arm 8. The above-mentioned blanking chute structure is further included. The two opposite sides of the loading hopper 3 are respectively rotatably arranged on the corresponding two fixed hooks 10 through mounting shafts 11, so that the loading hopper 3 can be located between the two sides of the conveying arm 8, and the blanking end 9 is located directly above the loading hopper 3. The mounting shafts 11 can be removed from the fixed hooks 10, thus facilitating disassembly, assembly and maintenance. Furthermore, a dust-proof cloth bag can be sleeved outside the chute 5. The overall length of the dust-proof cloth bag is equivalent to the overall length of the chute 5 when it is unfolded, and it can expand and contract with the expansion and contraction of the chute 5, thereby assisting in playing a better dust-proof role.

[0038] As Figure 1 、 2 shown, in more detail, the loading hopper 3 in this solution is exactly located below the blanking end 9. The material falls into the loading hopper 3 through the conveyor belt 17 provided on the conveying arm 8, and then falls downward into the first chute 5, and sequentially passes through all the chutes 5 downward and enters the lower blanking hood 4, and loading is realized through the blanking hood 4. Among them, the provided chute 5 has a structure that is larger at the top and smaller at the bottom, which is convenient for overlapping each other. The upper end of the chute 5 is fixedly connected with a mounting ring plate 12. The two sides of each mounting ring plate 12 are respectively connected in series through a connecting cable 13, and the upper and lower chutes 5 are continuously connected during the operation of the elevator 1, and are connected end to end with each other, that is, the lower end of the upper chute 5 is always located inside the lower chute 5, ensuring that the formed channel is not disconnected and the material is smoothly loaded. Among them, through holes can be provided on both sides of the mounting ring plate 12, and the connecting cable 13 is connected in series through the through holes, and the length of the connecting cable 13 is longer so that all the chutes 5 are connected in series by the connecting cable 13 when the blanking hood 4 is in the lowest position; above the first chute 5 at the highest level, the loading hopper 3 extends into it through the first guide chute 6 fixed to it to realize the transition of the material from the loading hopper 3 into the first chute 5.

[0039] As Figure 1 、 2As shown, furthermore, the blanking hood 4 includes a vertical cylinder section 15 located above and an open section 14 located below. Lower mounting brackets 16 are respectively fixedly connected to both sides of the vertical cylinder section 15, and the two rotating wheels 2 are respectively installed on the two lower mounting brackets 16. The chute 5 at the lowermost layer extends into the vertical cylinder section 15. The elevator 1 can specifically be a winch, that is, the winch is wound around the rotating wheel 2 through a sling 20, so as to realize the lifting and lowering of the blanking hood 4; Upper mounting brackets 7 are respectively fixedly connected to both sides of the feeding hopper 3, and the two elevators 1 are respectively installed on the two upper mounting brackets 7, that is, the winch is installed on the upper mounting bracket 7 to realize the fixed installation with the feeding hopper 3; More specifically, a second guide chute 18 is also fixedly connected inside the vertical cylinder section 15, and the chute 5 at the lowermost layer extends into the second guide chute 18. The lower end of the second guide chute 18 extends into the open section 14. The second guide chute 18 directly receives the material from the last chute 5, and then directly enables the material to enter the open section 14 for loading. The lower end of the open section 14 is larger and has an inverted horn structure, so that there is space between the material and the open section 14 when the material falls downward, and the material can smoothly spread outwards and be smoothly exported, ensuring smooth loading; More specifically, a blanking hopper 19 is also provided at the lower end of the second guide chute 18. The lower end of the blanking hopper 19 is smaller, so that the material in the second guide chute 18 can first fill the blanking hopper 19 and then fall downward. During the loading process, the lower end of the blanking hopper 19 can continuously abut against the material below (the elevator continuously lifts upward during the process), and the material is continuously and relatively constantly exported, smoothly realizing loading.

[0040] As Figure 1 , 2 shown, in a more detailed exemplary solution, the fixed hook 10 and the blanking hopper 19 can rotate relative to each other. Specifically, the fixed hook 10 has an inclined U-shaped structure, and vertically arranged fixed ear plates 21 are also fixedly connected to the opposite sides of the two fixed hooks 10. The two fixed ear plates 21 on the same fixed hook 10 are connected by a pin shaft 22. The fixed hook 10 is provided with an inclined opening through which the mounting shaft 11 can enter the U-shaped structure of the fixed hook 10, and then be locked through the connection of the pin shaft 22 and the fixed ear plate 21. However, the pin shaft 22 and the fixed ear plate 21 are not in contact with the mounting shaft 11. Therefore, the mounting shaft 11 and the fixed hook 10 can rotate relative to each other, so that even when the conveying arm 8 of the ship loader pitches up and down, the blanking hopper 19 can remain in a hanging state under its own weight and the weight of the structure below, that is, always keep all the chutes 5 in a vertical state, ensuring the smooth progress of the blanking process;

[0041] Furthermore, in the structure of the blanking chute 5 in this solution, the feeding hopper 3 is rotatably supported on the fixed hook 10 through the mounting shaft 11. At the same time, the feeding hopper 3 together with other structures can also be removed by an external hoisting device as long as the mounting shafts 11 on both sides are disengaged from the fixed hook 10, which is convenient for disassembly and installation and very convenient for maintenance.

[0042] Even further, the structure of the blanking chute 5 in this solution can be easily removed, so that it can be removed and not used when loading some materials that do not require dust prevention, such as sand and gravel with high water content, which will not generate dust during the falling process, thus avoiding the impact wear of these materials on the inner wall of the chute 5 and increasing the service life.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
