[0026] The utility model provides a belt unloading system, which can prevent dust from spilling out during the unloading process, thereby improving the surrounding working environment.
[0027] like Figure 1 As shown, an embodiment of the present invention provides a belt unloading system, comprising a unloading bin 1, a belt unloading trolley 2, a negative pressure forming device 3 and a dust removal device 4; a unloading port 11 is provided at the upper end of the unloading bin 1; the belt unloading trolley 2 comprises a mobile body 21 located above the unloading bin 1, a belt provided on the mobile body 21 and a unloading funnel 22 provided on the mobile body 21, one end of the belt extends into the feed port of the unloading funnel 22 for conveying material into the unloading funnel 22, and the lower end of the unloading funnel 22 is used to be inserted into the unloading port 11; the negative pressure forming device 3 is connected to the unloading bin 1 for forming a negative pressure in the unloading bin 1; the dust removal device 4 is provided on the mobile body 21 for absorbing dust generated at the feed port.
[0028] It can be understood that one end of the belt extends into the feed port of the unloading funnel 22 and can transport materials into the unloading funnel 22, and the lower end of the unloading funnel 22 can be inserted into the unloading port 11. In this way, when the mobile body 21 moves to the top of the unloading bin 1, the lower end of the unloading funnel 22 can be inserted into the unloading port 11 first, and the material delivered to the unloading funnel 22 by the belt will enter the unloading bin 1 through the unloading port 11, thereby realizing unloading.
[0029] In this embodiment, the belt unloading trolley 2 includes a mobile body 21 located above the unloading bin 1, a belt provided on the mobile body 21, and a unloading funnel 22 provided on the mobile body 21, and one end of the belt extends into the feed port of the unloading funnel 22, and the lower end of the unloading funnel 22 can be inserted into the unloading port 11, so that when the unloading funnel 22 is inserted into the unloading port 11, the material delivered to the unloading funnel 22 by the belt can be transported to the unloading bin 1 by the unloading funnel 22, and at the same time, by adding a negative pressure forming device 3, so that negative pressure is formed in the discharge bin 1. In this way, when the material enters the discharge bin 1 through the discharge port 11, the dust generated is not easy to overflow from the plug-in gap between the discharge funnel 22 and the discharge port 11 due to the negative pressure, thereby avoiding the dust overflow when the discharge funnel 22 feeds the material, thereby improving the working environment; and, by adding a dust removal device 4, the dust overflowed at the feed port can be absorbed, thereby avoiding the dust overflow during the belt feeding to the feed port, thereby further improving the working environment.
[0030] Alternatively, as Figure 1 As shown, a connection port 12 is provided at the upper end of the unloading bin 1; the negative pressure forming device 3 includes a negative pressure air duct 31 and a negative pressure fan, the negative pressure air duct 31 is fixedly connected to the connection port 12, and the negative pressure fan is communicated with the negative pressure air duct 31.
[0031] In this optional embodiment, the negative pressure forming device 3 is set as a negative pressure air duct 31 and a negative pressure fan, and the negative pressure air duct 31 is connected to the connection port 12 of the unloading bin 1, and the negative pressure fan is connected to the negative pressure air duct 31. In this way, after the negative pressure fan is started, the negative pressure fan can suck air into the unloading bin 1 through the negative pressure air duct 31 to form a negative pressure in the unloading bin 1. The structure of the negative pressure forming device 3 is relatively simple, which helps to reduce the difficulty of assembling the belt unloading system.
[0032] Alternatively, as Figure 1 and Figure 2 As shown, the negative pressure air duct 31 includes a connecting section 311 connected to the connecting port 12, and the connecting section 311 is arranged up and down.
[0033] It should be noted that the connecting section 311 is arranged in an up-down direction, which means that the entire length direction of the connecting section 311 is arranged in the up-down direction, but according to the installation requirements of the connecting section 311, a certain bend may appear in a certain part of the connecting section 311.
[0034] In this optional embodiment, the connecting section 311 of the negative pressure air duct 31 is arranged up and down, that is, the portion of the negative pressure air duct 31 close to the connecting port 12 is arranged up and down. In this way, if some dust adheres to the pipe wall of the connecting section 311 during shutdown, the dust can be driven to quickly fall back into the unloading bin 1 by knocking on the connecting section 311, which is conducive to the secondary utilization of the dust.
[0035] Alternatively, as Figure 1 and Figure 2 As shown, the negative pressure forming device 3 further includes a support column 32 extending up and down, and the support column 32 is arranged above the discharge bin 1; the connecting section 311 is fixed on the support column 32.

[0037] In this optional embodiment, the negative pressure forming device 3 also includes a support column 32 extending up and down, and the connecting section 311 is fixed on the support column 32, so that the support column 32 can better support and fix the negative pressure air duct 31 to prevent the negative pressure air duct 31 from collapsing and causing a safety accident.
[0038] Alternatively, as Figure 1 and Figure 2 As shown, the negative pressure forming device 3 also includes a bag dust collector 33, the air inlet of the bag dust collector 33 is connected to the end of the negative pressure air duct 31 away from the connecting port 12, and the air outlet of the bag dust collector 33 is connected to the negative pressure fan.

[0040] In this optional embodiment, the negative pressure forming device 3 also includes a bag dust collector 33, and the bag dust collector 33 is located between the negative pressure air duct 31 and the negative pressure fan. In this way, when the negative pressure fan starts to suck air, the dust carried by the air will be filtered and collected by the bag dust collector 33, and the air will be cleaned, thereby preventing dusty air from entering the negative pressure fan and causing damage to the fan.
[0041] Alternatively, as Figure 1 and Figure 2 As shown, there are two discharge ports 11, and the two discharge ports 11 are respectively located on both sides of the moving path of the mobile vehicle body 21; the discharge funnel 22 includes two discharge pipes 221, the upper ends of the two discharge pipes 221 are connected, the feed port is provided at the connection of the two discharge pipes 221, and the lower ends of the two discharge pipes 221 are used to insert the two discharge ports 11 respectively.
[0042] In this optional embodiment, there are two unloading ports 11, which are respectively located on both sides of the moving path of the mobile body 21, and the unloading funnel 22 includes two unloading pipes 221, the upper ends of the two unloading pipes 221 are connected, and the lower ends of the two unloading pipes 221 are respectively inserted into the two unloading ports 11, so that the unloading funnel 22 is a herringbone structure as a whole, and the mobile body 21 can be installed in the triangular area below the herringbone structure, which is conducive to improving the structural compactness of the belt unloading trolley 2.
[0043] Alternatively, as Figure 1 and Figure 2 As shown, the connecting port 12 is close to any one of the two discharge ports 11 .
[0044] Specifically, two connecting ports 12 may be provided, and correspondingly, two negative pressure air ducts 31 are also provided, and the two negative pressure air ducts 31 are fixedly connected to the two connecting ports 12 respectively.
[0045] In this optional embodiment, the connection port 12 is placed close to the discharge port 11 to ensure a negative pressure near the discharge port 11, thereby improving the effect of preventing dust from overflowing.
[0046] Alternatively, as Figure 1 and Figure 3As shown, the dust removal device 4 includes a shell 41 and a dust removal fan 42. The shell 41 is arranged on the mobile body 21. The wall of the shell 41 is provided with a dust suction port 412 and a connecting port 413 which are respectively connected to the inner cavity 411 of the shell 41. The dust suction port 412 faces the feed port, and the connecting port 413 is arranged horizontally opposite to the dust suction port 412. A filter is provided at the connecting port 413. The dust removal fan 42 is connected to the connecting port 413. When the dust removal fan 42 sucks air, the dust generated at the feed port is sucked into the inner cavity 411 of the shell 41 through the dust suction port 412.
[0047] It should be noted that the discharge funnel 22 can include two discharge pipes 221, and the feed port of the discharge funnel 22 can be set at the upper end connection of the two discharge pipes 221, and its direction can be arranged in the horizontal direction so that the end of the belt can extend into the feed port.

In this way, after the dust removal fan 42 is started, the dust generated at the feed port will be sucked into the inner cavity 411 of the shell 41 through the dust suction port 412, thereby realizing dust removal at the feed port, avoiding dust overflow when the belt feeds the material to the feed port, and preventing dust overflow from polluting the working environment.
[0049] Alternatively, as Figure 3 As shown, the bottom wall of the shell 41 is gradually recessed from the circumference to the middle to form a conical ash bin 43.
[0050] In this optional embodiment, the bottom wall of the shell 41 is gradually recessed from the circumference to the middle to form a conical ash bin 43, so as to collect dust filtered by the filter, facilitate the secondary utilization of dust, save energy and reduce dust emissions.
[0051] Alternatively, as Figure 3 As shown, the dust removal device 4 further includes an ash discharge pipe 44 , both ends of which are respectively connected to the small end of the conical ash bin 43 and the lower end of the discharge funnel 22 , and a valve 441 is provided on the ash discharge pipe 44 .
[0052] In this optional embodiment, an ash discharge pipe 44 is set between the conical ash bin 43 and the discharge funnel 22, and a valve 441 is provided on the ash discharge pipe 44.
