[0030] The following is combined with Figure 1 -Attached Figure 3 The utility model is described in further detail.
[0031] The embodiment of the utility model discloses a coal preparation jig which is convenient for uniform material discharge. Example 1
[0032] Reference Figure 1 The coal preparation jig for uniform discharging includes a body 1, the main work of coal preparation is completed by the body 1, and a lower hopper 10 is provided at the position for discharging on the body 1, and the selected material is discharged from the coal preparation jig through the lower hopper 10.
[0033] Reference Figure 1 and Figure 2 A plurality of guide plates 2 are evenly arranged in the width direction of the hopper 10. The guide plates 2 can be fixed to the inner wall of the hopper 10 by welding or bolting. The plurality of guide plates 2 divide the hopper 10 into a plurality of independent and relatively uniform discharge areas, so that the material is evenly dispersed through these discharge areas, avoiding blockage caused by excessive concentration of discharge points, effectively improving work efficiency and reducing maintenance costs. Example 2
[0034] Reference Figure 3 This embodiment differs from the first embodiment in that the number of guide plates 2 can be dynamically increased or decreased based on the material quantity and size, thereby varying the size of the material discharge area. A receiving box 3 for receiving the guide plates 2 is fixedly attached to the outer wall of the hopper 10. The guide plates 2 are movably mounted on the sidewalls of the hopper 10. The receiving box 3 is also provided with a drive assembly 4 for driving the guide plates 2 in and out of the hopper 10 or the receiving box 3.
[0035] Reference Figure 3 In this embodiment, the drive assembly 4 includes a screw 40, a handwheel 41, and a connector 42. In other embodiments, a cylinder or an electric push rod can also be used as the drive assembly 4. The screw 40 is vertically inserted through the side wall of the storage box 3. The handwheel 41 is installed at one end of the screw 40 outside the storage box 3 to drive the screw 40 to rotate.
[0036] Reference Figure 3The connecting member 42 is arranged between the screw 40 and the guide plate 2, and is used to achieve the purpose of the screw 40 being able to rotate relative to the guide plate 2 and driving the guide plate 2 to move back and forth. For example, the connecting member 42 can adopt a structural form in which a shell is fixedly connected to the guide plate 2, a circular plate is rotatably arranged in the shell, and the screw 40 is passed through the shell and fixed to the circular plate. The structural form that meets the use is not limited here.
[0037] Reference Figure 3 Multiple screws 40 are arranged alternately up and down along the width of the material discharge, leaving ample space for operators to operate the handwheel 41. Nuts 30 are welded to the outer wall of the container 3 at locations corresponding to the screws 40, and the screws 40 are threadedly engaged with the nuts 30. Limiting plates 100 are welded to the outer wall of the lower hopper 10 at locations corresponding to the guide plates 2. Limiting plates 100 are installed on both sides of the guide plates 2 to guide their movement and enhance their stability during operation.
[0038] When the size of each unloading area needs to be changed, the staff can shake the handwheel 41 in a targeted manner to move the guide plate 2, change the number and position of the guide plate 2 in the unloading hopper 10, and thus meet the unloading requirements. The drive component 4 is very easy to operate and can effectively improve operational efficiency.
[0039] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
