The plow type unloader uses a plow blade to scrape the material on the belt surface from one side or both sides. However, the plow blade of the plow type unloader needs to contact the belt, and long-term use will damage the belt. In addition, the additional plow type unloader will take up more space and make the conveying structure complicated. In addition, the plow type unloader is only suitable for powder unloading. For bulk materials such as lump ore and finished sintered ore, its unloading effect is poor and its scope of application is narrow. Therefore, there is an urgent need for a new intermediate discharging device that can achieve intermediate discharging without damaging the belt and complete unloading. Utility Model Content

It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0027] See also Figure 1 The utility model provides an intermediate discharging device for a belt conveyor, comprising an intermediate discharging device and a belt conveyor adapted thereto, wherein the belt conveyor comprises a belt and a redirecting roller 3, the redirecting roller 3 divides the conveying direction of the belt into a first conveying section 1 and a second conveying section 2, the height of the end of the first conveying section 1 is higher than the height of the second conveying section 2; the intermediate discharging device is arranged between the first conveying section 1 and the second conveying section 2, the intermediate discharging device comprises a shell 4, a discharging hopper 5 and a driving mechanism, intermediate discharging ports 41 are provided on both sides of the shell 4, the discharging hopper 5 is hinged between the shells 4, an inner channel 51 is provided through the discharging hopper 5, the top of the discharging hopper 5 has an inverted "V"-shaped guide plate 52, and the driving mechanism is used to drive the discharging hopper 5 to rotate so as to switch between the first state and the second state.

[0028] refer to Figure 1 When the discharge hopper 5 rotates downward to the first state, the end of the first conveying section 1 is connected to the middle discharge port 41 through the guide plate 52, that is, the material is lifted to a sufficient height by the first conveying section 1, and then the material is divided to both sides by the inverted "V"-shaped guide plate 52, and flows downward along the outer wall of the guide plate 52 to the middle discharge port 41, thereby achieving the purpose of middle discharge. Figure 2When the discharge hopper 5 rotates upward to the second state, the end of the first conveying section 1 is connected with the second conveying section 2 through the inner channel 51 of the discharge hopper 5, that is, the first conveying section 1 is connected with the inner channel 51 of the discharge hopper 5, so that the material falls onto the second conveying section 2 through the inner channel 51, and then the belt conveys the material to the head for discharge. Therefore, by switching the discharge hopper 5 between the first state and the second state, the belt conveyor can be switched between the middle discharge and the head discharge.

[0029] Furthermore, the discharge hopper 5 is arranged on one side of the redirecting roller 3 and is located between the first conveying section 1 and the second conveying section 2 , and one end of the discharge hopper 5 away from the first conveying section 1 is hinged to the inner side of the shell 4 .

[0030] Furthermore, the outer wall of the discharge hopper 5 contacts the inner wall of the housing 4, thereby preventing the material from leaking out of the gap in the first state. Furthermore, both ends of the discharge hopper 5 have rectangular openings, thereby increasing the inlet and outlet size of the inner channel 51, so that all the material falls into the inner channel 51 in the second state.

[0031] In one embodiment of the utility model, the driving mechanism includes an electric push rod 6, and the electric push rod 6 includes a retractable push rod 6, and the outer end of the push rod 6 is connected to one end of the discharge hopper 5. The extension and retraction of the push rod 6 drives the discharge hopper 5 to switch between the first state and the second state. Compared with setting an angle adjustment mechanism at the hinge point, the extension and retraction control of the push rod 6 is less prone to error, so that the rotation switching of the discharge hopper 5 is more accurate.

[0032] Furthermore, a connecting piece 53 is provided on the outer wall of one end of the discharge hopper 5 away from the first conveying section 1, and the connecting piece 53 is located in the middle of the discharge hopper 5, and the outer end of the push rod 6 is connected to the connecting piece 53. By providing the connecting piece 53, on the one hand, it is convenient for the push rod 6 to act on the discharge hopper 5; on the other hand, the distance between the push rod 6 and the discharge hopper 5 can be shortened, avoiding the use of an electric push rod 6 with a large stroke, and reducing costs.

[0033] Furthermore, a handle is installed on the outer wall of the discharge hopper 5. Preferably, the telescopic handle is respectively arranged on both sides of the connecting piece 53, so as to facilitate manual control of the rotation of the discharge hopper 5, which is safer and more reliable.

[0034] In one embodiment of the utility model, a dust box 7 is provided outside the middle discharge port 41, the bottom of the dust box 7 is open, and the top of the dust box 7 is inclined downward. By providing the dust box 7, the material flowing out of the middle discharge port 41 can be prevented from escaping everywhere, thereby controlling the flow direction of the material.

[0035] In one embodiment of the present invention, the first conveying section 1 gradually rises from the inlet end to the end. Since the use of the intermediate discharging device requires a sufficient height for material dispersion, the first conveying section 1 is gradually lifted using roller groups that are raised one by one, and then the belt is adjusted to a normal operating height through two groups of redirecting rollers 3.

[0036] The intermediate discharging device of the utility model can change the flow direction of the material by switching the discharging hopper between the first state and the second state, thereby realizing the switching of the belt conveyor between the intermediate discharging and the head discharging. This switching method is convenient and fast, saving space and equipment for process layout. The utility model changes the path and utilizes the self-flow of the material for unloading. There is no need to use a plow blade, and the belt will not be damaged. It is not limited to the form of the material and has a wide range of applications. Therefore, the utility model effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.
