Description

Technical Field

[0001] The utility model relates to the technical field of related structures for ship unloaders, in particular to a combined hopper and a ship unloader to which the combined hopper is applied. Background Technique

[0002] During the operation of a chain bucket ship unloader, the chain bucket scoops up materials from the cabin, unloads them into the receiving mechanism after lifting, then transfers them to the belt conveyor in the boom, and finally enters the belt conveyor system on the wharf through the central hopper and the discharge belt conveyor.

[0003] The side walls of the existing hoppers are solid plates, such as the hopper structure disclosed in the Chinese patent with the authorization announcement number: CN217534745 U. However, the materials unloaded by the ship unloader are sometimes sand and gravel and sometimes coal blocks. When discharging sand and gravel, the solid plates can block the materials; but when the hopper discharges bulk materials (such as coal blocks), a solid side plate is not required to block the materials; on the other hand, the solid side plates of the hopper are not conducive to the circulation of gas in the hopper. Summary of the Utility Model

[0004] To solve the technical problems in the background technique, the utility model proposes a combined hopper and a ship unloader to which the combined hopper is applied.

[0005] A combined hopper proposed by the utility model includes a back plate, a front plate and two side plates. The two side plates are arranged oppositely and the side plates are arranged between the back plate and the front plate. The back plate, the front plate and the side plates form a receiving groove with an opening. A communication hole communicating with the receiving groove is opened on the side plate, and a closing plate is detachably installed on the side plate. When the closing plate is installed on the side plate, the closing plate closes the communication hole.

[0006] When this hopper is applied to a ship unloader and the ship unloader discharges sand and gravel materials, the closing plate is installed on the side plate to close the communication hole so as to prevent the sand and gravel materials from discharging from the communication hole. When discharging large materials, the closing plate is detached from the side plate. The setting of the communication hole facilitates the circulation of gas in the receiving groove, so that when the hopper is convenient for discharging small materials and also convenient for discharging large materials, the large materials also have air flow in the receiving groove, thereby removing the dust on the surface of the large materials to a certain extent.

[0007] Preferably, in some embodiments, a plurality of the communication holes are opened on the side plate, and one closing plate is provided. One closing plate closes a plurality of the communication holes.

[0008] Furthermore, installing one closing plate to close a plurality of communication holes on one side plate can improve the working efficiency.

[0009] For the convenience of installing the closing plate, preferably, an installation groove is formed at one end of the side plate close to the opening, and the closing plate is detachably installed in the installation groove.

[0010] Preferably, when the closing plate is not installed in the installation groove, a net plate is installed in the installation groove, and the net plate is provided with a reinforcing portion that abuts against the inner wall of the installation groove.

[0011] The net plate in the installation groove facilitates the realization of the through hole to communicate with the receiving groove, and the reinforcing portion is arranged in the installation groove to increase the overall strength of the side plate, increasing the overall strength of the side plate on the premise of ensuring the smooth flow of gas in the installation groove.

[0012] Those skilled in the art can set the reinforcing portion as a protrusion on the net plate, the net plate abuts against one side wall of the installation groove, and the protrusion abuts against the other side wall of the installation groove. However, this limits the gas flow to a certain extent. Therefore, in some embodiments, preferably, the reinforcing portion includes an inner reinforcing block and an outer reinforcing block provided on the net plate, the inner reinforcing block abuts against the side surface of the installation groove close to the receiving groove, and the outer reinforcing block abuts against the side surface of the installation groove away from the receiving groove.

[0013] Preferably, multiple groups of the outer reinforcing blocks and the inner reinforcing blocks are provided, and there is a flow distance between any two adjacent groups of the outer reinforcing blocks and between any two adjacent groups of the inner reinforcing blocks.

[0014] To increase the support of the reinforcing portion for the two side walls of the installation groove in the side plate, preferably, one inner reinforcing block and one outer reinforcing block are opposite to each other.

[0015] To further increase its overall strength, preferably, there is a connecting portion between the opposite inner reinforcing block and outer reinforcing block.

[0016] Similar to the existing hopper, for the convenience of collecting materials, shovel teeth are provided on the surface of the front plate close to the opening.

[0017] A ship unloader includes the above-mentioned hopper.

[0018] In the present invention, the proposed combined hopper and the ship unloader to which it is applied enable the hopper to facilitate the unloading of small materials and also facilitate the unloading of large materials. When large materials are in the receiving groove, there is also air flow, thereby realizing the removal of dust on the surface of large materials to a certain extent.

[0019] The additional aspects and advantages of the present invention will be partially given in the following description, partially become apparent from the following description, or be understood through the practice of the present invention. Description of the Drawings

[0025] The following details the embodiments of the present utility model. The examples of the embodiments are shown in the drawings, where the same or similar symbols represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0026] As Figure 1 shown, a combined hopper includes a back plate 1, a front plate 2 and two side plates 3. Similar to existing hoppers, the two side plates 3 are arranged opposite to each other and the side plates 3 are arranged between the back plate 1 and the front plate 2. The back plate 1, the front plate 2 and the side plates 3 can be processed to form a hopper by welding or other means. The back plate 1, the front plate 2 and the side plates 3 form a receiving groove with an opening. Similar to the existing technology, there are connecting parts on the back plate 1 for connecting with a chain bucket unloader. Different from the existing hoppers, communication holes 4 communicating with a pre-receiving groove are opened on the side plates 3. The communication holes 4 introduce external air flow into the receiving groove, and communication holes 4 are opened on both side plates 3, thereby realizing the interaction between the gas in the receiving groove and the outside, enabling gas flow between the bulk materials in the receiving groove. A closing plate 5 is also detachably installed on the side plates 3. When the closing plate 5 is installed on the side plates 3, the closing plate 5 closes the communication holes 4. Specifically, the side plates 3 can be detachably installed on the side plates 3 by fixing parts such as bolts.

[0027] When the hopper is applied to an unloader and the unloader discharges sand and gravel materials, the closing plate 5 is installed on the side plates 3 to close the communication holes 4 to prevent the sand and gravel materials from being discharged through the communication holes 4. When discharging large-sized materials, the closing plate 5 is removed from the side plates 3. The arrangement of the communication holes 4 facilitates the flow of gas in the receiving groove, enabling the hopper to be convenient for discharging small materials and also for discharging large-sized materials. When discharging large-sized materials, there is also air flow between the large-sized materials in the receiving groove, thereby removing the dust on the surface of the large-sized materials to a certain extent.

[0028] In order to achieve the fluidity of the gas in the receiving groove and to increase to a certain extent the velocity of the other flows in the receiving groove, preferably in some embodiments, a plurality of communication holes 4 are formed in the side plate 3, and there is one closing plate 5. One closing plate 5 closes a plurality of communication holes 4. A plurality of communication holes 4 are formed in each side plate 3, and one closing plate 5 is provided on each side plate 3. One closing plate 5 closes the plurality of communication holes 4 on the cover side plate 3, thereby increasing the working efficiency.

[0029] For the convenience of installing the closing plate 5, preferably, an installation groove 30 is formed at one end of the side plate 3 close to the opening, and the closing plate 5 is detachably installed in the installation groove 30. As Figure 2 shown, during the installation of the closing plate 5, it is only necessary to place the closing plate 5 in the installation groove 30, and the side wall of the closing plate abuts against the inner side wall of the installation groove 30. Then, the closing plate 5 is fixed to the side plate 3 by existing fixing pins or screws. In this embodiment, an extension portion is provided above the closing plate 5. The extension portion is located outside the installation groove 30 of the side plate 3 and above the side plate 3. The installation extension portion is fixed to the side plate 3 by screws.

[0030] When the hopper transports large pieces of materials, as Figure 3 shown, preferably, when the closing plate 5 is not installed in the installation groove 30, a net plate 6 is installed in the installation groove 30. The net plate 6 has a reinforcing portion that abuts against the inner wall of the installation groove 30. The net plate 6 supports the reinforcing portion on the basis of ensuring the communication between the outside and the receiving groove, facilitating the positioning and installation of the supporting portion, and enhancing the overall strength of the large side plate 3 of the installation groove 30 without affecting the strength of the side plate 3 as a whole. While ensuring the gas flow in the installation groove 30, the overall strength of the side plate 3 is increased.

[0031] As Figure 3 shown, the net plate 6 is installed on the side plate 3 through a net plate 6 fixing member. A fixing frame 60 is provided on the outer periphery of the net plate 6. The net plate 6 fixing member fixes the net plate 6 to the side plate 3 through the fixing frame 60. The net plate 6 fixing member is a screw or a fixing pin. Of course, optionally in some embodiments, the fixing method of the net plate 6 can be the same as that of the closing plate 5. A top plate is provided above the net plate 6. The top plate is located outside the installation groove 30 and above the side plate 3. The top plate is fixed to the side plate 3 by a fixing pin.

[0032] As Figure 4 shown, preferably in the embodiment, the reinforcing portion includes an inner reinforcing block 7 and an outer reinforcing block 8 provided on the net plate 6. The outer reinforcing block 8 and the inner reinforcing block 7 do not block the communication holes; the inner reinforcing block 7 abuts against the side surface of the installation groove 30 close to the receiving groove, and the outer reinforcing block 8 abuts against the side surface of the installation groove 30 away from the receiving groove.

[0033] Preferably, multiple groups of outer reinforcing blocks 8 and inner reinforcing blocks 7 are provided, and there is a flow distance between any two adjacent groups of outer reinforcing blocks 8 and between any two adjacent groups of inner reinforcing blocks 7, that is, the outer reinforcing blocks 8 do not contact each other, and the inner reinforcing blocks 7 do not contact each other either, which is convenient for gas flow.

[0034] To increase the support of the reinforcing part for the two side walls of the installation groove 30 in the side plate 3, preferably, one inner reinforcing block 7 and one outer reinforcing block 8 are opposite to each other. Further, there is a connecting part between the opposite inner reinforcing block 7 and outer reinforcing block 8. Since the mesh plate 6 is a mesh structure, there is a contacting part between the opposite outer reinforcing block 8 and inner reinforcing block 7. The contacting parts of the outer reinforcing block 8 and the inner reinforcing block 7 can be welded to form a connecting part, or the outer reinforcing block 8 and the inner reinforcing block 7 can be connected by fixing parts such as fixing pins to form a connecting part. In this embodiment, preferably, the outer reinforcing block 8 is first welded to the mesh plate 6 and then the inner reinforcing block 7 is welded to the outer reinforcing block 8 opposite to it.

[0035] Similar to the existing hopper, in order to facilitate the collection of materials, shovel teeth 9 are provided on the surface of the front plate 2 close to the opening.
