Technical Field

[0001] The present application belongs to the technical field of material conveying devices, and in particular to a plough-type discharger. Background Art

[0002] The plow type discharger is widely used in the loading and unloading of bulk materials in China due to its simple structure, small installation space, low equipment failure rate, and easy remote automatic control. The plow type discharger is mainly composed of an electric push rod, a driving push rod, a roller group, a plow board, a rectangular discharge funnel, and an electronic control device. Its working characteristic is that when the discharge plow is pushed down by the electric push rod, the discharge plow board blocks the material and falls down, falling into the discharge funnel on both sides and the ore bin below.

[0003] Plough dischargers are widely used in the middle discharge of belt conveyors. They are simple in structure and highly economical. At present, feedback from the use of plough dischargers in production sites shows that the middle and rear parts of the rectangular discharge funnel are prone to blockage, resulting in production accidents such as overflow.

[0026] In order to enable technicians in the technical field to which the present application belongs to understand the present application more clearly, the technical solution of the present application is described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0027] For ease of understanding, in a plow discharger, the amount of material discharged increases gradually in the front of the discharge hopper, and reaches a maximum in the middle of the length of the discharge plowboard of the plow discharger. The traditional rectangular discharge hopper maintains the same cross-sectional area at each different discharge position of the plow discharger, while the plow discharger has a larger material discharge amount in the middle and rear sections, and the cross-sectional area of ​​the hopper is relatively small, which is very easy to cause blockage and overflow. Therefore, the present application is provided.

[0028] Figure 1 A schematic diagram of the structure of a plough-type discharger provided in this application, Figure 2 A top view of another plough type discharger provided in this application, referring to Figure 1 , 2 A plow type discharger provided in an embodiment of the present application includes a frame 1, a conveying belt 2, a discharge plowboard 3 and a discharge funnel 4.

[0029] The conveying belt 2 is rotatably disposed on the frame 1 .

[0030] The unloading plowboard 3 is connected to the frame 1 and is located above the conveying belt 2, and is used to block the materials carried by the conveying belt 2 to make the materials fall down.

[0031] The discharge funnel 4 is connected to the frame 1 and is used to receive and accommodate the falling materials. In the transport direction of the transport belt 2 , the cross-sectional area of ​​the middle cavity of the discharge funnel 4 is larger than the cross-sectional area of ​​the cavities on both sides of the discharge funnel 4 .

[0032] The frame 1 is the main supporting structure of the plow discharger. The conveying belt 2, the discharge plowboard 3 and the discharge funnel 4 can be connected to the frame 1. The conveying belt 2 can be rotated relative to the frame 1 to transport the materials. The discharge plowboard 3 on the conveying belt 2 can block the materials carried by the conveying belt 2 to make the materials fall. The materials fall into the discharge funnel 4 connected to the frame 1 and are transferred to the appropriate destination. In the transportation direction of the conveying belt 2, the materials will be transported to the discharge plowboard 3 and gradually accumulated, and the falling materials will gradually increase. The cross-sectional area of ​​the middle cavity of the discharge funnel 4 is larger than the cross-sectional area of ​​the cavities on both sides of the discharge funnel 4. The cross-sectional area of ​​the discharge funnel 4 at the part where the materials fall more is larger, which can accommodate more materials. Correspondingly, the part where the materials fall more can receive more materials, and the possibility of materials blocking the discharge funnel 4 is reduced, which solves the problem of overflow caused by the clogging of the plow discharger funnel to a certain extent. It is also conducive to improving the space utilization rate of the discharge funnel 4.

[0033] In some embodiments, in the transport direction of the transport belt 2, the cross-sectional area of ​​the central cavity of the discharge funnel 4 gradually increases and then gradually decreases.

[0034] The cross-sectional area of ​​the discharge funnel 4 changes slowly, which is convenient for preparation and for materials to fall into the discharge funnel 4, and also convenient for the transfer of materials.

[0035] In certain embodiments, the discharge funnel 4 may also be prepared as a structure with a cross-section that varies in height, or a structure with a cross-section that varies in steps, which is not limited in the present application.

[0036] In some embodiments, the discharge hopper 4 includes: an inner plate 41 and an outer plate 42 opposite to each other, and a connecting plate 43 connecting the inner plate 41 and the outer plate 42 . The inner plate 41 is closely connected to the frame 1 , and the outer plate 42 is an arc-shaped plate.

[0037] The inner and outer plates 42 are connected to the connecting plate 43, and the whole can be enclosed to form a discharge funnel 4. The inner plate 41 is closely connected to the frame 1 to play a connecting and supporting role. The outer plate 42 is an arc-shaped plate, which can reduce the overall occupied space while increasing the material that can be accommodated in the discharge funnel 4.

[0038] In some embodiments, the discharge funnel 4 can be integrally formed, or can be prepared into a circular structure, etc., which is not limited in the present application.

[0039] In some embodiments, the cross-section of the cavity of the discharge funnel 4 in the height direction is the same, which is convenient for preparing and transferring materials from the funnel to other parts.

[0040] In some embodiments, the discharge plowboard 3 is provided with a concave surface 31 extending to one side of the conveyor belt 2, and the concave surface 31 is used to block the material so that the material enters the discharge funnel 4. The concave surface 31 can increase the contact area with the material, so as to prevent more material from entering the discharge funnel 4.

[0041] In some embodiments, the discharge plowboard 3 is provided with at least one concave surface 31, and at least one discharge funnel 4 corresponds to the concave surface 31. This improves space utilization and facilitates the collection of materials.

[0042] In some embodiments, in the transport direction, the cross-sectional position of the largest area of ​​the discharge funnel 4 corresponds to 1 / 2 to 3 / 4 of the length of the concave surface 31. More materials can be received, effectively reducing the possibility of materials blocking the discharge funnel 4 and causing blockage and overflow.

[0043] In some embodiments, the recessed surface 31 may be a recessed curved surface, and two recessed curved surfaces may be provided. The two sides of the unloading plowboard 3 may protrude from the two sides of the conveyor belt 2 respectively. The two recessed surfaces 31 may extend from the middle of the unloading plowboard 3 to the two sides of the unloading plowboard 3 respectively, and the cross-sectional position with the largest area of ​​the unloading funnel 4 may be located at 2 / 3 of the length of the recessed surface 31, which can increase the collection of materials in a limited space and reduce the possibility of blockage and overflow.

[0044] It should be noted that the space of the environment where the plough type discharger is located is not large enough, so reducing the space required for the plough type discharger is also conducive to improving the versatility of the plough type discharger.

[0045] In some embodiments, the plough discharger further includes a ore bin 5, which is spaced apart from the discharge hopper 4 to receive the material in the discharge hopper 4. The ore bin 5 can facilitate the collection and transfer of materials.

[0046] In some embodiments, in the transport direction of the transport belt 2, the cross-sectional area variation trend of the ore bin 5 is consistent with the cross-sectional area variation trend of the discharge hopper 4. This facilitates the ore bin 5 to receive materials from the discharge hopper 4 and also helps to reduce the possibility of blockage and overflow.

[0047] In some embodiments, the orthographic projection of the discharge hopper 4 on the horizontal plane is located within the orthographic projection of the ore bin 5 on the horizontal plane, which facilitates the ore bin 5 to receive materials from the discharge hopper 4 and also helps to reduce the possibility of blockage and overflow.

[0048] In some embodiments, the plow discharger may further include an electric push rod 6 or a hydraulic drive structure, wherein the electric push rod 6 or the hydraulic drive connects the frame 1 and the discharge plow board 3, so that the discharge plow board 3 rotates and rises or falls relative to the frame 1 and the conveying belt 2, so as to facilitate the control of the falling of the material.

[0049] Although the preferred embodiments of the present application have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present application.

[0050] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
