[0031] Material conveying components are widely used in fields such as construction, mining, and metallurgy. They transport materials (such as building stone, mined minerals, and metallurgical ores) to material handling equipment for crushing and screening. The processed materials can then be used in various applications, such as roadbed materials and concrete sand. However, when materials contain high levels of sediment and fine particles, these materials can easily accumulate or even fall off the material conveying components during transportation.

[0032] To reduce space occupancy, the power system of the material conveying component is centrally located below the material conveying component. However, this also brings new problems. Materials falling from the material conveying component are easily accumulated on top of the power system. Due to the narrow space between the power system and the material conveying component, cleaning is more difficult, which consumes a lot of manpower and increases cleaning and maintenance costs.

[0033] like Figure 1 In the utility model, the first direction is defined as the direction along the X axis, the second direction is defined as the direction along the Y axis, and the third direction is defined as the direction along the Z axis, i.e. the up-down direction, and the direction indicated by the arrow is upward, wherein the first direction, the second direction and the third direction are perpendicular to each other.

[0034] It can be understood that the above-mentioned coordinate system is intended to illustrate the approximate position relationship, connection relationship or movement relationship of the components, and does not mean that the components in the utility model need to be strictly arranged or connected according to the above-mentioned coordinate system. The first direction, the second direction and the third direction can be flexibly adjusted according to actual needs by those skilled in the art, and the first direction, the second direction and the third direction only represent spatial directions and have no substantial meaning.

[0035] In combination with Figure 1 and Figure 3 , the power system material receiving shell of the utility model comprises a main body 10 and a material receiving assembly 20. The power system is arranged below the material conveying assembly 30. The main body 10 is arranged in the space between the material conveying assembly 30 and the power system, and at least a part of the main body 10 covers above the power system. The material receiving assembly 20 is arranged on the upper end of the main body 10 and located between the material conveying assembly 30 and the main body 10. In combination with Figure 2 , the material receiving assembly 20 comprises a receiving member 21 for receiving the materials dropped by the material conveying assembly 30. The receiving member 21 is configured to be movable relative to the main body 10 and has a first state and a second state relative to the main body 10.

[0036] Referring to Figure 1 and Figure 2 , Figure 1 is a structural schematic view of the receiving member 21 in the first state, Figure 2 is a structural schematic view of the receiving member 21 in the second state in an example scheme. When the receiving member 21 is in the first state, the receiving member 21 is fixed relative to the main body 10 and used for receiving the materials dropped by the material conveying assembly 30. When the receiving member 21 is in the second state, the receiving member 21 is movable relative to the main body 10. At least a part of the receiving member 21 can move out of the space between the material conveying system and the power system. When the receiving member 21 completely moves out of the space, the receiving member 21 can be detached from the main body 10.

[0037] The material receiving assembly 20 is arranged at the upper end of the main body 10 and can receive the material falling from the material conveying assembly 30. In particular, when the material contains a large amount of sand and gravel, the material receiving assembly 20 can effectively collect the material. The main body 10 cooperates with the material receiving assembly 20 to prevent the material from directly leaking through the material conveying assembly 30 to the power system. The receiving member 21 is configured to be movable relative to the main body 10. When it is necessary to clean the accumulated material, the receiving member 21 can be adjusted to the second state, so that the cleaning can be conveniently, quickly and effectively performed. After the cleaning is completed, the receiving member 21 is adjusted to the first state, so that the cleaning and maintenance costs are reduced. In addition, the overall structure is simple, and the operation is convenient.

[0038] It can be understood that the main body 10 can only cover the power system, or the main body 10 includes a cavity, and the power system is arranged in the cavity, and the upper end of the power system is covered by the main body 10.

[0039] As shown in Figure 2 , the receiving member 21 includes a dismounting end 201. The receiving member 21 can be adjusted at one side of the dismounting end 201 to switch between the first state and the second state.

The first material blocking member 211 can block the material on the receiving member 21 to prevent the material from falling from the receiving member 21 along the first direction. The material can be effectively collected, and the workers can conveniently clean the collected material.

[0041] In an optional solution, the first material blocking member 211 is fixedly connected or integrally formed with the receiving member 21. In another optional solution, the first material blocking member 211 is detachably connected with the receiving member 21. Different specifications of the first material blocking member 211 can be replaced according to the type of the material conveyed by the material conveying assembly 30, so that the application range is wide and the material blocking effect is good.

[0042] Exemplarily, in combination with Figure 1 and Figure 2 , the receiving member 21 is arranged to be inclined. The height of the receiving member 21 gradually increases from the dismounting end 201 to the side away from the dismounting end 201 along the first direction. The workers can conveniently dismount the receiving member 21, and the material on the receiving member 21 can be collected at the dismounting end 201 of the receiving member 21 under the action of gravity, so that the workers can conveniently clean the collected material.

[0043] Exemplarily, the upper end of the main body 10 is obliquely arranged and parallel to the receiving member 21, so that when the receiving member 21 is in the second state, the worker can move the receiving member 21 out in a time-saving and labor-saving manner.

[0044] In an example scheme of the utility model, as shown in the figure, Figure 4 The receiving assembly 20 comprises a first limiting member 22 and a second limiting member 23, the first limiting member 22 is arranged at the upper end of the main body 10 and located at one side of the main body 10 close to the dismounting end 201, the second limiting member 23 is arranged at the dismounting end 201 of the receiving member 21 and cooperates with the first limiting member 22 and realizes detachable connection through the fixing member, the worker can realize the fixing or dismounting of the receiving member 21 and the main body 10 by adjusting the fixing member, so as to switch the receiving member 21 between the first state and the second state.

[0045] Exemplarily, the first limiting member 22 and the second limiting member 23 are both provided with a fixing hole for installing the fixing member, as shown in the figure, Figure 4 The fixing member comprises a through connecting member 241 and a clamping member 242, the through connecting member 241 is arranged in the fixing hole, and the size of the end of the through connecting member 241 away from the dismounting end 201 is larger than the size of the fixing hole, so that the end face of the through connecting member 241 away from the dismounting end 201 cannot be separated from the fixing hole, the dismounting end 201 of the through connecting member 241 is provided with a clamping groove 243, the clamping groove 243 is a through groove penetrating the two side faces of the through connecting member 241 in the length direction, and a base shaft 244 is arranged in the clamping groove 243, the two ends of the base shaft 244 are connected with the groove walls of the clamping groove 243 in the width direction, a base groove 245 is arranged on the clamping member 242, the base groove 245 penetrates the clamping member 242 in the axial direction of the base shaft 244, the clamping member 242 can be accommodated in the clamping groove 243, and the base shaft 244 is arranged in the base groove 245, the clamping member 242 can move relative to the through connecting member 241 through the cooperation of the base groove 245 and the base shaft 244, and has a fixed state and a dismounting state.

[0046] When the clamping member 242 is in the fixed state, referring to Figure 4 The clamping member 242 is arranged in the length direction of the clamping groove 243 and at a certain angle with the through connecting member 241, so as to fix the through connecting member 241 in the fixing hole and fix the first limiting member 22 and the second limiting member 23, at this time, the receiving member 21 is in the first state, the receiving member 21 is fixed on the upper end of the main body 10 and can realize material receiving;

[0047] When it is necessary to adjust the receiving member 21 to the second state, first pull out the clamping member 242 along the length direction of the clamping groove 243. At this time, the base shaft 244 and the base groove 245 are slidably matched until one end of the clamping member 242 is accommodated in the clamping groove 243. Then, the clamping member 242 is rotated around the base shaft 244 to make the clamping member 242 coaxial with the connecting member 241. The clamping member 242 is in the disassembled state, and the second limiting member 23 is released from the first limiting member 22. At this time, the receiving member 21 can move relative to the main body 10. The staff can pull the receiving member 21 out from between the material conveying assembly 30 and the main body 10, or directly remove the receiving member 21 from the main body 10 to facilitate cleaning of the material accumulated on the receiving member 21.

[0048] In an example solution of the present utility model, combined with Figure 2 and Figure 5 The receiving assembly 20 includes side blocks 25. The two side blocks 25 are provided at the upper end of the main body 10 and are located on both sides of the receiving member 21 in the second direction. The side blocks 25 extend along the first direction. The side blocks 25 are in contact with both ends of the receiving member 21 in the second direction, or a certain gap is left between the two. The receiving member 21 is movably provided between the two side blocks 25. The side blocks 25 are configured to limit the movement of the receiving member 21 in the second direction. When the receiving member 21 is in the second state, refer to Figure 2 The side block 25 can guide the receiving part 21 and enable the receiving part 21 to move along the first direction relative to the main body 10, making it convenient for the staff to pull the receiving part 21 out from the upper end of the main body 10, or directly remove the receiving part 21 from the main body 10, and clean up the materials accumulated on the receiving part 21.

[0049] Exemplarily, the receiving member 21 includes a wheel body, and the receiving member 21 is movably arranged between the side blocks 25 through the wheel body. The wheel body can be arranged at the lower end of the receiving member 21 and cooperate with the upper end of the main body 10, or can be arranged at both ends of the receiving member 21 in the second direction and cooperate with the side blocks 25. Optionally, the wheel body is a roller.

[0050] For example, Figure 5 As shown, a guide groove 251 is provided on the side stopper 25, and the guide groove 251 penetrates the side stopper 25 along the second direction, and the guide groove 251 extends along the first direction. A guide member 252 is passed through the guide groove 251, and one end of the guide member 252 is connected to the receiving member 21. When the receiving member 21 is in the second state, the guide member 252 can move in the guide groove 251 along the first direction. The guide member 252 cooperates with the guide groove 251 to play a guiding role when the receiving member 21 moves relative to the main body 10, reducing the resistance when the staff pulls the receiving member 21, and ensuring the stable movement of the receiving member 21, avoiding the problem of secondary falling of materials due to the shaking of the receiving member 21.

[0051] Optionally, the guide member 252 and the receiving member 21 can be detachably connected, for example, by screwing.

[0052] like Figure 5 As shown, the end of the guide member 252 away from the receiving member 21 is connected to a locking member 253, and the area of ​​the positive projection of the locking member 253 in the second direction is larger than the area of ​​the positive projection of the guide groove 251 in the second direction. The function of the locking member 253 is to prevent the end of the guide member 252 away from the receiving member 21 from falling out of the guide groove 251, so as to ensure the sliding fit between the guide member 252 and the guide groove 251.

[0053] Alternatively, the locking member 253 may be a structure of the guide member 252 itself, i.e., the locking member 253 and the guide member 252 are integrally formed, or the locking member 253 may be fixedly connected or detachably connected to the guide member 252. In a preferred embodiment, the locking member 253 and the guide member 252 are detachably connected to facilitate maintenance and repair by staff.

[0054] When the receiving part 21 needs to be adjusted to the second state without being separated from the main body 10, it is only necessary to adjust the fixing part. Due to the cooperation between the guide part 252 and the guide groove 251, the groove wall of the guide groove 251 can limit the guide part 252 in the first direction, so that the receiving part 21 will not fall from the main body 10; if the receiving part 21 needs to be removed to clean materials or replace the receiving part 21, the fixing part can be adjusted and the guide part 252 can be removed to separate the receiving part 21 from the main body 10. The disassembly and assembly is convenient, simple and efficient.

[0059] Optionally, the guide member 252 is connected to the first supporting member 261 or the pressing member 27.

[0060] Optionally, as shown in Figure 6 the pressing member 27 is provided with a second material blocking member 271, the second material blocking member 271 extends along the third direction and protrudes from the upper end surface of the pressing member 27, and the second material blocking member 271 can block the material on the receiving member 21 in the second direction, so as to prevent the material from falling off from the side of the receiving member 21.

[0061] In an optional solution, the second material blocking member 271 is fixedly connected to or integrally formed with the pressing member 27, different specifications of the pressing member 27 can be replaced according to the type of the material conveyed by the material conveying assembly 30, and the material conveying assembly 30 can be applied to different material conveying scenes.
