Description

Technical Field

[0001] The utility model relates to the technical field of unloading devices, in particular to a plough-type unloader. Background Art

[0002] Plough type unloader is widely used in mining, metallurgy, power plants, coal yards, docks and other industries. It is a commonly used segmented unloading device on belt conveyors. It is installed on the middle frame of the belt conveyor to perform unloading and control the conveying direction of materials. It can unload materials transported by the conveyor belt into the hopper or other places.

[0003] For example, the Chinese patent with the announcement number CN203237769U discloses an electro-hydraulic plow-type unloader, which includes a plow-type unloader and a mobile frame that are used in conjunction with each other. The plow-type unloader provided on the mobile frame includes an electro-hydraulic push rod and a unloading plow head that are used in conjunction with each other. The unloading plow head is provided on a roller group, and the roller group is provided on a roller bracket; the mobile frame includes a frame and a walking wheel assembly that are used in conjunction with each other, and a reducer power source and a brake are respectively provided at both ends of the frame; a unloading chute is provided below the plow-type unloader, and the unloading chute includes a mobile chute and a fixed chute that are used in conjunction with each other.

[0004] However, the plow-type discharger in the above patent still has certain problems: when unloading fast-moving mixed materials, powder materials or materials with high viscosity, there are problems of material falling and blocking at the discharge plow head. That is, when the material passes through the discharge plow head, the material is easy to stick or accumulate on the discharge plow head and cannot fall off in a short time, causing material blocking and subsequent material falling. Utility Model Content

[0005] The utility model aims at solving the problems in the prior art and provides a plow-type discharger capable of active unloading, thereby solving the serious leakage and blockage problems of the prior art in the passive unloading by tilting the unloading plow head.

[0006] The technical solutions adopted in this utility model are as follows:

[0007] A plow-type discharger includes a bracket, a hydraulic cylinder is hingedly connected to the bracket, a discharge plowshare is hingedly connected to one end of the hydraulic cylinder, the discharge plowshare includes a fixed frame and a moldboard, the fixed frame is hingedly connected to the hydraulic cylinder, the moldboard is fixedly mounted on the fixed frame, and the discharge plowshare also includes a discharge assembly, the discharge assembly is fixedly mounted on the fixed frame and located below the moldboard, and the discharge assembly is movable in the length direction of the discharge plowshare. The provided discharge assembly can generate an active horizontal force on the material during the discharge process, pushing the material in the discharge direction, thereby preventing the material from sticking or accumulating on the discharge plowshare and being unable to fall off within a short period of time, causing material blockage and subsequent material falling.

[0008] Preferably, the unloading assembly includes a connecting plate fixed to a fixed frame, a driving motor and a reducer provided on the connecting plate, the input end of the reducer being connected to the driving motor, the output end of the reducer being connected to a driving shaft, the connecting plate being rotatably connected to a supporting shaft, a unloading belt being wrapped around the outside of the driving shaft and the output shaft, the driving shaft being used to drive the unloading belt to rotate. The unloading belt is provided so that the unloading belt rotates under the action of the driving motor during the unloading process, thereby completing the active guidance of the material.

[0009] Preferably, at least one unloading plate is provided on the outside of the unloading belt. By providing the unloading plate, when the unloading belt rotates, the unloading plate contacts the material, thereby increasing the contact area between the unloading assembly and the unit material, and further improving the unloading efficiency.

[0010] Preferably, a plurality of stripper plates are evenly spaced outside the discharge belt, and the height of the stripper plates is the same as the height of the discharge belt. By evenly distributing the plurality of stripper plates, the material discharge rate can be kept constant during the discharge process. At the same time, keeping the height of the stripper plates consistent with the height of the discharge belt facilitates the production of the discharge belt and the assembly of the stripper plates.

[0011] Preferably, a sealing pad is fixedly provided below the fixing frame. By providing the sealing pad, material leakage between the fixing frame and the transport belt can be reduced.

[0012] Preferably, a laser sensor is provided on the moldboard. By providing the laser sensor, when the material is accumulated to a certain height and the laser sensor is triggered, the speed of the unloading belt can be accelerated to reduce the accumulation of materials.

[0013] The advantages of the present invention are as follows: The unloading assembly, when in motion, actively exerts a horizontal force on the material during unloading, pushing it in the unloading direction. This prevents material from sticking or accumulating on the unloading plowshare, preventing it from falling off quickly and causing material blockage and subsequent material dropout. The unloading belt, driven by a drive motor, rotates during unloading, actively guiding the material. The unloading plate, when rotating, contacts the material, increasing the contact area between the unloading assembly and the material per unit, further improving unloading efficiency. The uniform distribution of the unloading plates ensures a consistent unloading rate during unloading. Keeping the height of the unloading plates consistent with the height of the unloading belt facilitates the production and assembly of the unloading belt. The sealing gasket reduces material leakage between the fixed frame and the conveyor belt. The laser sensor, when triggered by the laser sensor after material reaches a certain height, accelerates the unloading belt's rotation speed, reducing material accumulation.

Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0020] Example:

[0021] like Figure 1 and Figure 2 As shown, a plow type discharger includes a bracket 1, a hydraulic cylinder 2 is hinged on the bracket 1, and a discharging plow head is hinged at one end of the hydraulic cylinder 2. The discharging plow head includes a fixed frame 3 and a plow board 4, the fixed frame 3 is hinged to the hydraulic cylinder 2, and the plow board 4 is fixed on the fixed frame 3. The discharging plow head also includes a discharging assembly, which is fixed on the fixed frame 3 and is located below the plow board 4. The discharging assembly can move in the length direction of the discharging plow head. With such an arrangement, the discharging assembly can generate an active horizontal force on the material during the discharging process, pushing the material to move in the discharging direction, thereby avoiding the material from sticking or accumulating on the discharging plow head and being unable to fall off in a short time, causing material blockage and subsequent material falling.

[0022] In this embodiment, the unloading assembly includes a connecting plate 5, which is fixed to the fixed frame 3. A drive motor 6 and a reducer 7 are provided on the connecting plate 5. The input end of the reducer 7 is connected to the drive motor 6, and the output end of the reducer 7 is connected to the drive shaft. The connecting plate 5 is also rotatably connected to a support shaft. A unloading belt 8 is wrapped around the outside of the drive shaft and the output shaft. The drive shaft is used to drive the unloading belt 8 to rotate. The unloading belt 8 is rotated by the drive motor 6 during the unloading process, thereby actively guiding the material.

[0023] At least one unloading plate 9 is provided on the outside of the unloading belt 8, and in the present embodiment, several unloading plates 9 are evenly provided on the outside of the unloading belt 8, and the height of the unloading plates 9 is the same as the height of the unloading belt 8. With such an arrangement, the unloading plates 9 can be in contact with the material when the unloading belt 8 rotates, thereby increasing the contact area between the unloading assembly and the unit material, and further improving the unloading efficiency. By evenly distributing several unloading plates 9, the unloading rate of the material can be always the same during the unloading process. At the same time, keeping the height of the unloading plates 9 consistent with the height of the unloading belt 8 can facilitate the production of the unloading belt 8 and the assembly of the unloading plates 9. In the present embodiment, the unloading plates 9 and the unloading belt 8 are integrally formed.

[0024] In this embodiment, a polyurethane sealing pad is further fixedly provided under the fixing frame 3. By so providing the sealing pad, the material leakage between the fixing frame 3 and the transport belt can be reduced.

[0025] In this embodiment, a laser sensor is provided on the plow blade 4, and the laser sensor is used to detect whether the material has reached the warning height. Through the laser sensor, the rotation speed of the unloading belt 8 can be accelerated when the laser sensor is triggered after the material is accumulated to a certain height. In this embodiment, the rotation speed of the unloading belt 8 is set with ten gears to facilitate the speed adjustment according to the changes of different types or different volumes of materials per unit time, thereby reducing the material accumulation phenomenon.

[0026] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
