Description

Technical Field

[0001] This utility model relates to the field of material unloading and spreading technology, and in particular to a material unloading and spreading device. Background Technology

[0002] In the production process of environmentally friendly materials, the materials need to be conveyed through a discharge device to achieve the fabrication.

[0003] A search revealed a prior art unloading device (publication number: CN111703916B), comprising a housing, a first unloading shaft, and a second unloading shaft. The housing has an unloading chamber, and both the first and second unloading shafts are rotatably disposed within the unloading chamber, with the second unloading shaft positioned above the first unloading shaft. The housing has an unloading port communicating with the unloading chamber, and the first and second unloading shafts are used to drive the material in the unloading chamber to be unloaded from the unloading port. The unloading port includes a first unloading port corresponding to the first unloading shaft and a second unloading port corresponding to the second unloading shaft. The first unloading port is located below the first unloading shaft, and the second unloading port is located below the second unloading shaft, with the first and second unloading ports arranged in a stepped distribution.

[0004] Existing technology uses multiple augers to achieve mixing and discharging by adjusting the rotation direction of the auger blades. Each auger is driven by a separate motor, which makes the control and structure relatively complex. This causes some inconvenience when switching between feeding and mixing materials. The complex structure is not only difficult to control, but also has disadvantages in terms of later maintenance and usage costs. The design of multiple augers will occupy the space of the material box, limiting the actual storage space of the material box.

[0005] Therefore, we propose a material unloading and distribution device. Utility Model Content

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a material unloading and distribution device, comprising:

[0008] The material bin has a cavity, and a hopper for feeding material into the cavity is fixedly installed on the top of the material bin;

[0009] A conveying structure is set inside the material box cavity for mixing and discharging materials. The conveying structure includes a conveying shell, a feed inlet, a return outlet, and a pushing assembly. The conveying shell is fixedly installed at the bottom of the material box. The feed inlet and return outlet are opened on the side wall of the conveying shell. The pushing assembly is set inside the conveying shell cavity for pushing materials to move radially along the conveying shell.

[0010] A shielding structure is installed on the outer wall of the conveyor housing to block the return port. The shielding structure includes a baffle, a linear guide rail, and an electric push rod. The linear guide rail is fixedly installed with the material box, the baffle is slidably connected with the linear guide rail, the electric push rod is fixedly connected with the material box, and the output shaft of the electric push rod is fixedly connected with the baffle.

[0011] In a preferred embodiment of this utility model, the pushing assembly includes blades, convection grooves, and turbulence-disrupting parts.

[0012] In a preferred embodiment of this utility model, the blade is a spiral plate, and the convection groove is formed on the spiral surface of the blade, and the convection groove is a rectangular groove.

[0013] In a preferred embodiment of this utility model, the turbulence part includes a rectangular main body, with several extensions on both sides of the main body. The extensions and the main body together form a leaf vein-like rib, which is welded and fixed to the blade.

[0017] This utility model provides a material unloading and spreading device. It has the following beneficial effects:

[0018] 1. This unloading and feeding device, when feeding and discharging, pulls a baffle along a linear guide rail via the output shaft of an electric actuator, blocking the return port. At this time, the material enters through the feed port and is guided out by the conveyor shell to achieve unloading and feeding. When discharging stops, in order to suppress the segregation of the material in the hopper, the electric actuator pushes the baffle along the linear guide rail to allow the return port to leak out. The reverse rotation of the geared motor allows the material to enter from the return port and exit from the feed port, ensuring the fluidity of the material in the hopper and thus suppressing segregation. It has two functions: unloading and mixing. The switching between the two functions is simple and convenient, easy to operate, suitable for actual production, small in size, and large in actual storage space of the hopper.

[0019] 2. This unloading and feeding device drives the blades to rotate via a geared motor. The spiral blades can push the material inside the conveying shell. The rotation direction of the blades can be adjusted by changing the forward and reverse rotation of the geared motor. Multiple convection grooves are provided to promote the flow of material between two adjacent pitches of the blades, allowing a small amount of material to pass through and promoting interlayer mixing. Multiple turbulence-inducing parts are provided. The vein-shaped turbulence-inducing parts can enhance the turbulence effect when the material contacts the spiral surface of the blades. On the one hand, it can inhibit the adhesion of the geared motor, and on the other hand, it can further enhance the extrusion and mixing effect of the material. Attached Figure Description

[0026] A material unloading and spreading device, such as Figure 1 and Figure 2 As shown, it includes:

[0027] The material bin 10 has a cavity, and a hopper for feeding material into the cavity is fixedly installed on the top of the material bin 10.

[0028] The conveying structure is set inside the material box 10 for mixing and discharging materials. The conveying structure includes a conveying shell 11, a feed inlet 12, a return outlet 13, and a pushing assembly. The conveying shell 11 is fixedly installed at the bottom of the material box 10. The feed inlet 12 and the return outlet 13 are opened on the side wall of the conveying shell 11. The pushing assembly is set inside the cavity of the conveying shell 11 for pushing materials to move radially along the conveying shell 11. The conveying shell 11 is cylindrical. A sealing plate is welded to the end of the conveying shell 11 located inside the cavity of the material box 10. The feed inlet 12 and the return outlet 13 are respectively opened near the two ends of the conveying shell 11.

[0029] like Figure 2 and Figure 3 As shown, a shielding structure is installed on the outer wall of the conveying shell 11 to block the return port 13. The shielding structure includes a baffle 20, a linear guide rail 21, and an electric push rod 22. The linear guide rail 21 is fixedly installed with the material box 10, the baffle 20 is slidably connected with the linear guide rail 21, the electric push rod 22 is fixedly connected with the material box 10, and the output shaft of the electric push rod 22 is fixedly connected with the baffle 20. The baffle 20 is an arc-shaped plate, and a sealing gasket is fixedly installed on the inner circumference of the baffle 20. The sealing gasket fits against the outer wall of the conveying shell 11. A slider is fixedly installed at the lower end of the baffle 20, and the slider is slidably connected with the groove of the linear guide rail 21. An installation hole is opened at the end of the material box 10. The electric push rod 22 is fixed and sealed to the end of the material box 10 through a flange. A bushing is fixedly installed on the inner wall of the material box 10, and a sealing ring is provided inside the bushing. The output shaft of the electric push rod 22 passes through the bushing and is connected to the baffle 20. The length of the baffle 20 is greater than the length of the return port 13.

[0030] In this scheme, the forward and reverse rotation of the geared motor 33 mainly adjusts whether the material enters from the feed port 12 or the return port 13. When discharging material, the output shaft of the electric push rod 22 pulls the baffle 20 to slide along the linear guide rail 21, and the baffle 20 blocks the return port 13. At this time, the material enters through the feed port 12 and is guided out by the conveying shell 11 to achieve unloading and discharging. When discharging stops, in order to suppress the segregation of the material in the hopper 10, the electric push rod 22 pushes the baffle 20 to slide along the linear guide rail 21 to allow the return port 13 to leak out. The reverse rotation of the geared motor 33 allows the material to enter from the return port 13 and be discharged from the feed port 12, ensuring the fluidity of the material in the hopper 10 and thus suppressing segregation. It has two functions: unloading and mixing. The switching between the two functions is simple and convenient, easy to operate, and suitable for actual production, such as the production and preparation of environmental protection materials.

[0031] like Figure 4 and Figure 5As shown, the feeding assembly includes a blade 30, a convection groove 31, and a turbulence-disrupting part 32. The blade 30 is rotatably connected to the conveying shell 11. The blade 30 has several convection grooves 31. The blade 30 is also fixedly installed with several turbulence-disrupting parts 32. The material box 10 is equipped with a geared motor 33 to drive the blade 30 to rotate. The blade 30 is a spiral plate. The convection grooves 31 are opened on the spiral surface of the blade 30. The convection grooves 31 are rectangular grooves. The turbulence-disrupting part 32 includes a rectangular main body. Several extensions are provided on both sides of the main body. The extensions and the main body together form a leaf vein-like rib. The rib is welded and fixed to the blade 30.

[0032] In this scheme, in order to push the material, the blade 30 is driven to rotate by the geared motor 33. The spiral blade 30 can push the material in the conveying shell 11. The rotation direction of the blade 30 can be adjusted by adjusting the forward and reverse rotation of the geared motor 33. Multiple convection grooves 31 are set to promote the flow of material within two adjacent pitches of the blade 30, allowing a small amount of material to pass through and promoting interlayer mixing. Multiple turbulence parts 32 are set. The leaf vein-shaped turbulence parts 32 can improve the turbulence effect when the material contacts the spiral surface of the blade 30. On the one hand, it can suppress the adhesion of the geared motor 33, and on the other hand, it can further improve the extrusion and mixing effect of the material.

[0033] It should be noted that the output shaft of the geared motor 33 passes through the material box 10 and is connected to the blade 30 through a coupling. The end of the material box 10 needs to be equipped with corresponding sealing facilities, such as sealing rings or sealing bearings, to ensure the sealing effect of the contact position between the output shaft of the geared motor 33 and the material box 10. The geared motor 33 and the electric push rod 22 need to be connected to the PLC controller and power supply. In order to ensure corrosion resistance and durability, the conveyor shell 11, blade 30, baffle 20 and linear guide 21 can be made of stainless steel and have a silicon nitride coating on the outside.

[0034] The working principle of this utility model is as follows: Raw materials for producing environmentally friendly materials are fed from the hopper into the material box 10. The blades 30 are driven to rotate clockwise by the geared motor 33. The spiral blades 30 can push the material in the conveying shell 11. The rotation direction of the blades 30 can be adjusted by adjusting the forward and reverse rotation of the geared motor 33. Multiple convection grooves 31 are provided to promote the flow of material within two adjacent pitches of the blades 30, allowing a small amount of material to pass through and promoting interlayer mixing. Multiple turbulence-inducing parts 32 are provided. The vein-shaped turbulence-inducing parts 32 can enhance the turbulence effect when the material contacts the spiral surface of the blades 30. When the material is distributed... During material feeding, the output shaft of the electric actuator 22 pulls the baffle 20 to slide along the linear guide rail 21, and the baffle 20 blocks the return port 13. At this time, the material enters through the feed port 12 and is discharged through the guide of the conveying shell 11 to achieve unloading and material distribution. When material discharge stops, in order to suppress the segregation of the material in the hopper 10, the electric actuator 22 pushes the baffle 20 to slide along the linear guide rail 21 to allow the return port 13 to leak out. The reverse rotation of the reduction motor 33 causes the material to enter from the return port 13 and be discharged from the feed port 12, ensuring the fluidity of the material in the hopper 10 and thus suppressing segregation, thereby achieving the mixing of the material.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
