Description

Technical Field

[0001] The present invention relates to the technical field of port equipment, and particularly relates to a bucket elevator ship unloader conveying system and a ship unloader. Background Art

[0002] Bucket elevator ship unloaders are widely used in port bulk cargo ship unloading terminals and have prominent environmental protection advantages. During the operation of a bucket elevator ship unloader, inside the bucket arm, the buckets are lifted to the top of the bucket arm by a hoist, and then the buckets are reversed to unload the material onto a conveyor belt for transportation.

[0003] In a traditional bucket elevator ship unloader, the position of the bucket arm is fixed relative to the structure of the bucket machine. To improve the material taking efficiency, a new method of taking material from the front of the bucket mouth is designed. The bucket arm is designed to be movable back and forth along the ship width direction, and at the same time, the entire boom is designed to be liftable. Due to the liftable characteristic of the boom, the intermediate conveying structure for transporting materials needs to change in height and position as the boom rises and falls. Therefore, the intermediate conveying structure is formed by multiple transport units arranged in a bendable manner to adapt to the rise and fall of the boom.

[0004] However, at the connection between multiple transport units, a funnel-shaped joint is usually used to convey the material from the upper-level transport unit to the lower-level transport unit. During the process of material falling, the material will be exposed to the external environment, and at this time, the material speed is relatively fast, which is easy to spread into the air and cause environmental pollution. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is: to overcome the defect that in the existing conveying system of a bucket elevator ship unloader, the material is easy to spread into the air and cause environmental pollution during the process of transferring materials, so as to provide a bucket elevator ship unloader conveying system in which the material is not easy to spread into the air.

[0025] Optionally, the funnel assembly includes:

[0026] A material receiving funnel, which is communicated with the blanking conduit;

[0027] A material distribution hopper, connected to the material receiving hopper, and the material distribution hopper is adapted to transfer the material to the outside.

[0028] The present invention also provides a ship unloader, comprising:

[0029] The bucket elevator conveyor system according to any one of the above solutions.

[0030] The technical solution of the present invention has the following advantages:

[0031] 1. The present invention provides a bucket elevator conveyor system, comprising: a boom conveying unit disposed on the boom along the extending direction of the boom; a transfer conveying unit connected to the boom conveying unit and adapted to transfer the material exported from the boom conveying unit; a hopper assembly adapted to collect and unload the material to the outside; a discharge conveying unit, one end of which is hermetically connected to the transfer conveying unit, and the other end is correspondingly disposed opposite to the large opening end of the hopper assembly, and the discharge conveying unit is adapted to expand and contract with the lifting of the boom.

[0032] In the bucket elevator conveyor system provided by the present invention, the discharge conveying unit is hermetically arranged with the transfer conveying unit at least at one end close to the transfer conveying unit, and at the same time, the discharge conveying unit itself is in a sealed state, ensuring that when the material is transferred between the upper conveying unit, i.e., the transfer conveying unit, and the lower conveying unit, i.e., the discharge conveying unit, it will not diffuse into the air to pollute the environment, thereby improving the environmental protection performance of the whole machine. By setting the discharge conveying unit to be adapted to expand and contract with the lifting of the boom, it is avoided that the discharge conveying unit is deformed or even damaged when the boom moves, so that the sealed connection between the discharge conveying unit and the transfer conveying unit is more stable and reliable, ensuring the stability of the operation of the bucket elevator conveyor system and the sealed transportation of the material, and overcoming the defect that in the prior art, the material is easily diffused into the air to pollute the environment during the transfer of the material by the conveyor system of the bucket elevator.

[0033] 2. The present invention provides a bucket elevator conveyor system, wherein the discharge conveying unit comprises: a front support frame hermetically connected to the transfer conveying unit; a telescopic conduit configured as a telescopic structure, and the telescopic conduit is connected to the front support frame and adapted to convey the material to the hopper assembly.

[0034] The front support frame is hermetically connected to the end of the transfer conveying unit to prevent materials from diffusing into the air at the connection and polluting the environment. The front support frame is hinged to the end of the transfer conveying unit and is adapted to rotate with the lifting movement of the transfer conveying unit, improving the smoothness of the position change of the bucket unloader conveying system and the stability of transportation. The telescopic structure of the telescopic conduit enables the discharging conveying unit to expand and contract with the lifting of the boom, ensuring the structural stability of the discharging conveying unit during the lifting process of the boom when the bucket unloader conveying system is working.

[0035] 3. The present invention provides a bucket unloader conveying system. The telescopic conduit includes: a steering conduit connected to the front support frame and adapted to guide the materials to fall vertically; a blanking conduit connected to the steering conduit and adapted to convey the materials in the vertical direction to the funnel assembly.

[0036] The steering conduit is a telescopic structure with a certain bending angle, adapted to guide the materials entering the steering conduit from the end of the transfer conveying unit to change the falling direction and finally guide the materials to fall vertically, thereby accelerating the transfer speed of the materials in the subsequent conveying process, avoiding blockage and piling of materials at structures such as the blanking conduit, and improving the transportation efficiency of the bucket unloader conveying system. The blanking conduit further restricts the transfer direction of the materials, confines the materials in the blanking conduit for sealed transportation, further ensuring that the materials will not diffuse into the air and pollute the environment during blanking, improving the environmental protection performance of the whole machine. At the same time, the blanking conduit is arranged in the vertical direction to accelerate the transfer speed of the materials and improve the transportation efficiency of the bucket unloader conveying system.

[0037] 4. The present invention provides a bucket unloader conveying system. At least part of the area inside the steering conduit is provided with replaceable wear-resistant tiles.

[0038] The replaceable wear-resistant tiles are mainly attached to the inner wall of the steering conduit by bolting. Their function is to improve the structural strength of the parts of the steering conduit that are frequently impacted by materials and prevent the collapse of the steering conduit structure itself. At the same time, the replaceable feature allows for regular maintenance and replacement of severely worn wear-resistant tiles to improve the service life of the whole machine.

[0039] 5. The present invention provides a bucket unloader conveying system. The discharging conveying unit further includes a hinged slider arranged at one end of the blanking conduit close to the funnel assembly and slidably hinged to the funnel assembly. The hinged slider is adapted to change the position of the blanking conduit at the large end of the opening of the funnel assembly.

[0040] The articulated slider is adapted to slidably hinge the blanking conduit on the funnel assembly, enabling the blanking conduit to slide along the end face of the large end of the opening of the funnel assembly under the action of the articulated slider, thereby changing the position of the blanking conduit at the large end of the opening of the funnel assembly, preventing the material from continuously impacting the funnel assembly at the same landing point and causing deformation of the structure of the funnel assembly, and improving the service life of the funnel assembly.

[0041] 6. The present invention provides a conveying system for a chain bucket ship unloader, further comprising a connecting rod, with both ends respectively hinged to the transfer conveying unit and the main beam.

[0042] The setting of the connecting rod enables the end of the transfer conveying unit to be connected to the main beam, improving the operating stability of the conveying system of the chain bucket ship unloader. At the same time, the hinged connection method provides a certain amount of movement space for the transfer conveying unit, and plays a certain buffering effect when the carrier of the conveying system of the chain bucket ship unloader encounters strong wind interference.

[0043] 7. The present invention provides a conveying system for a chain bucket ship unloader, and the connecting rod is a telescopic rod.

[0044] Setting the connecting rod as a telescopic rod enables the height difference between the front end and the end of the transfer conveying unit to be changed under the action of the telescopic rod. By autonomously adjusting the telescopic rod, the slope of the transfer conveying unit for transporting materials is directly adjusted, thereby adjusting the speed at which the materials finally fall into the funnel assembly, that is, controlling the departure speed of the materials according to the characteristics of the materials, and avoiding large impacts on the subsequent funnel assembly and the terminal conveying unit due to too fast speed of the materials.

[0045] 8. The present invention provides a conveying system for a chain bucket ship unloader, further comprising: a receiving port, arranged above the boom conveying unit, and the boom conveying unit and the receiving port are arranged at intervals in the horizontal direction; a receiving conveying unit, arranged between the receiving port and the boom conveying unit, and the extending direction of the receiving conveying unit is arranged at an angle with the extending direction of the boom, and the receiving conveying unit is adapted to receive the materials led out from the receiving port and convey the materials to the boom conveying unit along its own extending direction.

[0046] By arranging a receiving conveying unit at an angle with the extending direction of the boom conveying unit between the receiving port and the boom conveying unit, the materials are linearly transported along the extending direction of the receiving conveying unit to the edge and then fall onto the boom conveying unit, realizing the transfer of the materials led out from the receiving port to the boom conveying unit via the receiving conveying unit, ensuring the smoothness of the conveying process, and there are no obstructive components during the conveying process, avoiding material blockage and spillage caused by traditional rotary feeding, thereby improving work efficiency, reducing the failure rate of the whole machine, and improving the environmental protection effect.

[0047] 9. The present invention provides a conveying system for a bucket unloader, and the funnel assembly includes: a material receiving funnel communicating with the blanking conduit; a material distributing funnel connected to the material receiving funnel, and the material distributing funnel is adapted to transfer the material to the outside.

[0048] After the material receiving funnel introduces the material from the unloading conveying unit, the material directly falls into the area of the material distributing funnel. A material distributing plate is provided in this area, and its function is to adjust through a mechanical or / and hydraulic structure so that the material falls into the corresponding terminal conveying unit according to the terminal scheduling arrangement and is finally transported out of the site.

[0049] 10. The present invention further provides a ship unloader, including: the conveying system of the bucket unloader described in any of the above advantages.

[0050] For the ship unloader provided by the present invention, the unloading conveying unit is at least hermetically arranged with the transfer conveying unit at one end close to the transfer conveying unit, ensuring that when the material is transferred between the upper conveying unit, i.e., the transfer conveying unit, and the lower conveying unit, i.e., the unloading conveying unit, it will not diffuse into the air and cause environmental pollution, improving the environmental protection performance of the whole machine; further, the front support frame and the telescopic conduit itself are both closed tubular structures with good sealing performance, thus ensuring the sealed conveyance of the material; the material is sequentially conveyed to the outside through the material receiving conveying unit, the boom conveying unit, the transfer conveying unit, the unloading conveying unit, and the terminal conveying unit, realizing the unloading of the material.

[0061] Embodiment 1

[0062] This embodiment provides a bucket chain ship unloader conveying system, as Figures 1 - 3As shown in the figure. The position of the bucket arm of the traditional chain bucket unloader is fixed relative to the structure of the chain bucket machine. In order to improve the material taking efficiency, a new method for taking materials from the front of the bucket mouth is designed. The bucket arm is designed to move back and forth along the ship width direction, and at the same time, the entire boom is designed to be liftable. Due to the liftable characteristic of the boom, the intermediate conveying structure for conveying materials needs to change in height and position as the boom rises and falls. Therefore, the intermediate conveying structure is formed by multiple sections of transportation units that are bendable to adapt to the lifting of the boom.

[0063] However, at the transfer junction between multiple sections of transportation units, a funnel-shaped joint is usually used to convey materials from the upper-level transportation unit to the lower-level transportation unit. During the process of material dropping, the materials will be exposed to the external environment, and at this time, the material speed is relatively fast, which is easy to spread into the air and cause environmental pollution.

[0064] For this reason, this embodiment provides a conveying system for a chain bucket unloader, including: a boom conveying unit 502, a transfer conveying unit 503, a funnel assembly 513, a discharging conveying unit 504, etc.

[0065] The boom conveying unit 502 is arranged on the boom 601 along the extending direction of the boom 601.

[0066] Specifically, as Figure 1 shown, the materials 30 dug by the material taking device 100 arranged on the bucket arm 104 are suitable to fall onto the boom conveying unit 502, and the boom conveying unit 502 is suitable for conveying the materials 30 dug by the material taking device 100 along the extending direction of the boom 601.

[0067] The transfer conveying unit 503 is connected to the boom conveying unit 502 and is suitable for transferring the materials exported from the boom conveying unit 502.

[0068] Specifically, the connection mode between the transfer conveying unit 503 and the boom conveying unit 502 is hinged. Through the hinged connection mode, the transfer conveying unit 503 and the boom conveying unit 502 can rotate relative to the hinge point.

[0069] Furthermore, a second joint 507 is arranged at the hinge point between the transfer conveying unit 503 and the boom conveying unit 502. The upper and lower ends of the second joint 507 are open, and the material conveying on the boom conveying unit 502 is suitable to be transferred to the transfer conveying unit 503 via the second joint 507.

[0070] The funnel assembly 513 is suitable for collecting and unloading materials to the outside.

[0071] Specifically, the funnel assembly 513 is directly fixed on the frame main body 10 and is suitable for moving synchronously with the frame main body 10.

[0072] Furthermore, the conveying system of the bucket unloader also includes a terminal conveying unit 505. The terminal conveying unit 505 is arranged below the hopper assembly 513 and on the terminal foundation 40, and is adapted to receive the materials falling into the hopper assembly 513 and convey the materials to the terminal foundation 40 or a vehicle or conveying equipment for transporting the materials, etc., so as to collect and unload the materials to the outside.

[0073] It should be noted that "up and down" refers to Figure 1 "up" and "down" indicated by the arrows in

[0074] The discharging conveying unit 504 is hermetically connected to the transfer conveying unit 503 at one end and correspondingly arranged with the large opening end of the hopper assembly 513 at the other end. The discharging conveying unit 504 is adapted to expand and contract with the lifting of the boom 601.

[0075] Specifically, the discharging conveying unit 504 is a conveying structure connected between the transfer conveying unit 503 and the hopper assembly 513, and guides the materials transported by the transfer conveying unit 503 into the hopper assembly 513, ensuring the smoothness of material transfer.

[0076] Furthermore, for the discharging conveying unit 504 being adapted to expand and contract with the lifting of the boom 601, as an implementation manner, at least part of the structure of the discharging conveying unit 504 is a folding telescopic pipe; as another implementation manner, at least part of the structure of the discharging conveying unit 504 is a flat folding telescopic pipe.

[0077] It should be noted that the large opening end of the hopper assembly 513 is the end Figure 1 close to the discharging conveying unit 504 as shown.

[0078] In the conveying system of the bucket unloader provided in this embodiment, the discharging conveying unit 504 is hermetically arranged with the transfer conveying unit 503 at least at the end close to the transfer conveying unit 503, and at the same time, the discharging conveying unit 504 itself is in a sealed state, ensuring that when the materials are transferred between the upper conveying unit, i.e., the transfer conveying unit 503, and the lower conveying unit, i.e., the discharging conveying unit 504, they will not diffuse into the air to pollute the environment, improving the environmental protection performance of the whole machine. By setting the discharging conveying unit 504 to be adapted to expand and contract with the lifting of the boom 601, it is avoided that the discharging conveying unit 504 is deformed or even damaged when the boom 601 moves, so that the sealed connection between the discharging conveying unit 504 and the transfer conveying unit 503 is more stable and reliable, ensuring the stability of the conveying system of the bucket unloader and the sealed transportation of materials, and overcoming the defect that in the prior art, during the process of transferring materials by the conveying system of the bucket unloader, the materials are easily diffused into the air to pollute the environment.

[0079] On the basis of the above embodiments, as a further defined embodiment, as Figure 2 shown, the discharging and conveying unit 504 includes: a front support frame 5041 and a telescopic conduit.

[0080] The front support frame 5041 is hermetically connected to the transfer and conveying unit 503.

[0081] Specifically, the front support frame 5041 is hermetically connected to the end of the transfer and conveying unit 503 to prevent materials from diffusing into the air at the connection and polluting the environment.

[0082] It should be noted that in this embodiment, the "front end" and "end" refer to the direction of material transportation of the transfer and conveying unit 503. The position where the material is first contacted is the front end, and the position where the material will leave is the end.

[0083] Furthermore, the front support frame 5041 is hinged to the end of the transfer and conveying unit 503 and is adapted to rotate with the lifting movement of the transfer and conveying unit 503, improving the smoothness of the position change of the bucket wheel unloader conveyor system and the stability of transportation.

[0084] The telescopic conduit is configured as a telescopic structure. The telescopic conduit is connected to the front support frame 5041 and is adapted to convey materials to the funnel assembly 513.

[0085] Specifically, the telescopic structure of the telescopic conduit enables the discharging and conveying unit 504 to undergo telescopic changes with the lifting of the boom 601, ensuring the structural stability of the discharging and conveying unit 504 during the lifting process of the boom 601 when the bucket wheel unloader conveyor system is working.

[0086] Furthermore, both the front support frame 5041 and the telescopic conduit itself are closed tubular structures, having good sealing performance, thereby ensuring the sealed conveyance of materials.

[0087] On the basis of the above embodiments, as a further defined embodiment, as Figure 2 shown, the telescopic conduit includes: a steering conduit 5042 and a blanking conduit 5043.

[0088] The steering conduit 5042 is connected to the front support frame 5041 and is adapted to guide the materials to fall vertically.

[0089] Specifically, the steering conduit 5042 is a telescopic structure with a certain bend angle, adapted to guide the materials entering the steering conduit 5042 from the end of the transfer and conveying unit 503 to change the falling direction, and finally guide the materials to fall vertically, thereby accelerating the transfer speed of the materials in the subsequent conveying process, avoiding material blockage and accumulation at structures such as the blanking conduit 5043, and improving the transportation efficiency of the bucket wheel unloader conveyor system.

[0090] Furthermore, the steering duct 5042 is a telescopic structure with a certain bend angle, suitable for changing the mapping of the end of the steering duct 5042 in the vertical direction, that is, changing the position where the end of the steering duct 5042 is mapped on the funnel assembly 513, so as to cooperate with the subsequent blanking duct 5043 and the articulated slider 5044 to change the position where the material falls into the large opening end of the funnel assembly 513, preventing the structure of the funnel assembly 513 from deforming due to the continuous impact of the material at the same landing point on the funnel assembly 513.

[0091] The blanking duct 5043 is connected to the steering duct 5042 and is suitable for transporting the material in the vertical direction to the funnel assembly 513.

[0092] Specifically, the blanking duct 5043 further restricts the transfer direction of the material, confines the material in the blanking duct 5043 for sealed transportation, further ensures that the material will not spread into the air during blanking to pollute the environment, improves the environmental protection performance of the whole machine. At the same time, the blanking duct 5043 is arranged in the vertical direction to accelerate the transfer speed of the material and improve the transportation efficiency of the conveyor system of the bucket unloader.

[0093] On the basis of the above embodiments, as a further defined embodiment, at least part of the area inside the steering duct 5042 is provided with a replaceable wear-resistant tile.

[0094] Specifically, the replaceable wear-resistant tile is mainly attached to the inner wall of the steering duct 5042 by bolting. Its function is to improve the structural strength of the part of the steering duct 5042 that is frequently impacted by the material, and avoid the collapse of the structure of the steering duct 5042 itself. At the same time, the replaceable feature allows for regular maintenance and replacement of the severely worn wear-resistant tiles to improve the service life of the whole machine.

[0095] On the basis of the above embodiments, as a further defined embodiment, as Figure 2 shown, the unloading and conveying unit 504 further includes an articulated slider 5044, which is arranged at one end of the blanking duct 5043 close to the funnel assembly 513 and is slidably hinged to the funnel assembly 513. The articulated slider 5044 is suitable for changing the position of the blanking duct 5043 at the large opening end of the funnel assembly 513.

[0096] Specifically, the articulated slider 5044 is suitable for slidably hinging the blanking duct 5043 to the funnel assembly 513, so that the blanking duct 5043 can slide along the end face of the large opening end of the funnel assembly 513 under the action of the articulated slider 5044, thereby changing the position of the blanking duct 5043 at the large opening end of the funnel assembly 513, preventing the structure of the funnel assembly 513 from deforming due to the continuous impact of the material at the same landing point on the funnel assembly 513, and improving the service life of the funnel assembly 513.

[0097] Further, as a preferred embodiment, a control system is provided to manually or automatically control the articulated slider 5044, and manually or positionally control the final landing position of the material.

[0098] The upward opening end of the funnel assembly 513 is rectangular, and the diameter of the blanking conduit 5043 is less than or equal to the width (the side parallel to the coastline) of this rectangle, that is, the shorter side. And the blanking conduit 5043 can slide along the long side of the rectangular opening (i.e., the side perpendicular to the coastline), thereby improving the sealing performance at the connection between the blanking conduit 5043 and the funnel assembly 513, further preventing the material from spreading into the air and polluting the environment, and improving the environmental protection performance of the whole machine.

[0099] Based on the above embodiment, as a further limited embodiment, as Figure 1 shown, the bucket elevator conveyor system further includes a connecting rod, with both ends respectively hinged to the transfer conveying unit 503 and the main beam 12.

[0100] Specifically, a connecting rod is provided to connect the end of the transfer conveying unit 503 to the main beam 12, improving the operating stability of the bucket elevator conveyor system. At the same time, the hinged connection method provides a certain amount of movement space for the transfer conveying unit 503, and plays a certain buffering effect when the carrier of the bucket elevator conveyor system encounters strong wind interference.

[0101] Based on the above embodiment, as a further limited embodiment, as Figure 1 shown, the connecting rod is a telescopic rod 512.

[0102] Specifically, the connecting rod is set as the telescopic rod 512, so that the height difference between the front end and the end of the transfer conveying unit 503 can be changed under the action of the telescopic rod 512. By autonomously adjusting the telescopic rod 512, the slope of the transfer conveying unit 503 for transporting materials is directly adjusted, thereby adjusting the speed at which the materials finally fall into the funnel assembly 513, that is, controlling the departure speed of the materials according to the characteristics of the materials, and avoiding large impacts on the subsequent funnel assembly 513 and the dock conveying unit 505 due to too fast speed of the materials.

[0103] Based on the above embodiment, as a further limited embodiment, as Figure 1 、 Figure 3 shown, the bucket elevator conveyor system further includes: a receiving port 1041, a receiving conveying unit 501, etc.

[0104] The receiving port 1041 is arranged above the boom conveying unit 502, and the boom conveying unit 502 and the receiving port 1041 are arranged at intervals in the horizontal direction.

[0105] The material receiving and conveying unit 501 is arranged between the material receiving port 1041 and the boom conveying unit 502. The extending direction of the material receiving and conveying unit 501 is set at an angle with the extending direction of the boom 601. The material receiving and conveying unit 501 is adapted to receive the material exported from the material receiving port 1041 and convey the material to the boom conveying unit 502 along its own extending direction.

[0106] It should be noted that the "downward" refers to the direction where the "down" pointed by the arrow in Figure 3 is located; the "horizontal direction" refers to the "horizontal direction" pointed by the arrow in Figure 3 ; the fact that the boom conveying unit 502 and the material receiving port 1041 are arranged at intervals in the horizontal direction means that the material receiving port 1041 is not directly above the boom conveying unit 502; the material receiving and conveying unit 501 is arranged between the material receiving port 1041 and the boom conveying unit 502 means that the material receiving and conveying unit 501 is located below the material receiving port 1041 and above the boom conveying unit 502; the extending direction of the material receiving and conveying unit 501 is set at an angle with the extending direction of the boom 601, so that the material receiving port 1041 and the boom conveying unit 502 arranged at intervals in the horizontal direction can be connected through the material receiving and conveying unit 501. Preferably, the extending direction of the material receiving and conveying unit 501 and the boom conveying unit 502.

[0107] Specifically, by arranging the material receiving and conveying unit 501 with an angle to the extending direction of the boom conveying unit 502 between the material receiving port 1041 and the boom conveying unit 502, the material is linearly transmitted along the extending direction of the material receiving and conveying unit 501 to the edge and then falls onto the boom conveying unit 502, realizing the transfer of the material exported from the material receiving port 1041 to the boom conveying unit 502 via the material receiving and conveying unit 501, ensuring the smoothness of the conveying process, and there are no obstructive components during the conveying process, avoiding the material blockage and spilling caused by traditional rotary feeding, thereby improving work efficiency, reducing the failure rate of the whole machine, and improving the environmental protection effect.

[0108] Furthermore, the belt conveying system of the chain bucket ship unloader further includes: a first joint 506, which is arranged between the material receiving and conveying unit 501 and the boom conveying unit 502. Both ends of the first joint 506 are open, and it is adapted to export the material on the material receiving and conveying unit 501 to the boom conveying unit 502.

[0109] It should be noted that the first joint 506 can be set with openings at both the upper and lower ends. Among them, the upper opening end is arranged corresponding to the end of the material receiving and conveying unit 501 away from the material receiving port 1041, and the lower opening end is located directly above the boom conveying unit 502. After the material is conveyed by the material receiving and conveying unit 501, it enters the first joint 506 from the upper opening end of the first joint 506, and then is exported from the lower opening end to the boom conveying unit 502, and then is further conveyed by the boom conveying unit 502; alternatively, the upper end of the first joint 506 is directly connected to the material receiving and conveying unit 501, and the lower end is an opening end, which can also achieve exporting the material on the material receiving and conveying unit 501 to the boom conveying unit 502.

[0110] Furthermore, by arranging the first joint between the material receiving and conveying unit 501 and the boom conveying unit 502, it is further ensured that the material on the material receiving and conveying unit 501 is smoothly transferred to the boom conveying unit 502, effectively avoiding material spillage, thereby enhancing the environmental protection effect.

[0111] Furthermore, a dust-proof cover 511 is arranged outside the boom conveying unit 502. The dust-proof cover can prevent the material on the boom conveying unit 502 from spilling out. Further optionally, a curtain 510 is arranged at one end of the dust-proof cover of the boom conveying unit 502 close to the material receiving and conveying unit 501. The material on the boom conveying unit 502 passes through the curtain 510 and then enters the dust-proof cover 511 of the boom conveying unit 502, further avoiding material spillage.

[0112] On the basis of the above embodiments, as a further limited embodiment, as Figure 1 、 Figure 2 shown, the funnel assembly 513 includes: a material receiving funnel 5131 and a material distributing funnel 5132.

[0113] The material receiving funnel 5131 is connected to the blanking conduit 5043.

[0114] The material distributing funnel 5132 is connected to the material receiving funnel 5131, and the material distributing funnel 5132 is adapted to transfer the material to the outside.

[0115] Specifically, after the material receiving funnel 5131 introduces the material from the unloading and conveying unit 504, the material directly falls into the area of the material distributing funnel 5132. A material distributing plate is arranged in this area, and its function is to adjust through mechanical or / and hydraulic structures so that the material falls into the corresponding terminal conveying unit 505 according to the terminal scheduling arrangement and is finally transferred out of the field. The terminal conveying unit 505 includes but is not limited to belts, chain plates, etc.

[0116] In this embodiment, conveyor belts are arranged on the material receiving and conveying unit 501, the boom conveying unit 502, and the transfer conveying unit 503, and the conveyor belts are used to convey materials.

[0117] Further, the conveyor belt is a leather belt.
