Description
Technical Field
[0001] The utility model relates to the technical field of hoppers, in particular to a hopper with a discharge port flow control device. Background Art
[0002] In many industries such as mining and grain processing, hoppers are essential for material transfer and crushing. It is a common choice to change the material flow of the hopper by setting a control structure at the hopper outlet, but different control structures have different effects. Common ones include cylinder-controlled baffles and lifting rod-controlled baffles. Cylinder-controlled baffles can be automatically electrified and have more precise control, but the cost is slightly higher and a certain installation position needs to be reserved. Lifting rod-controlled baffles are very common in today's elevators and other fields, but the structure is not beautiful or convenient enough. Utility Model Content
[0003] The utility model aims to provide a hopper with a discharge port flow control device, which can conveniently change the shielding area of the hopper discharge port, thereby changing the flow rate of the material discharge, has a simple structure, low cost, and is convenient and effective.
[0004] In order to achieve the above-mentioned purpose, the utility model provides a hopper with a discharge port flow control device, comprising a main body, a discharge port is arranged at the bottom of the side wall of the main body, a flow control device is arranged on the discharge port, the flow control device comprises a plug plate, an adjustment rod and an adjustment plate, the plug plate is arranged at the back of the discharge port, a horizontal connecting plate is vertically arranged on the top of the plug plate, the center of the top surface of the horizontal connecting plate is movably connected to the middle part of the adjusting rod through a right-angle connecting plate, one end of the adjusting rod is hinged to the main body, the other end of the adjusting rod is movably connected to the adjusting plate, the adjusting plate is fixed to the side of the main body and parallel to the plug plate. Preferably, an arc-shaped slide groove is arranged on the adjustment plate, an adjustment knob is arranged in front of the adjustment plate, and the adjustment knob is hinged to the other end of the adjusting rod through a screw passing through the arc-shaped slide groove.
[0005] Preferably, the horizontal connecting plate and the right-angle connecting plate are movably connected via long screws.
[0006] Preferably, right-angle fixing plates protruding outward are arranged on the side walls of the main body on both sides of the discharge port, and a discharge pipe is arranged between the two right-angle fixing plates, and the front end surface of the discharge pipe covers the discharge port.
[0007] Preferably, the insert plate is located between the discharge port and the front end surface of the feed pipe.
[0008] Therefore, the utility model adopts a hopper with a discharge port flow control device of the above structure, and changes the inclination angle of the adjustment rod by pulling and adjusting the rotation, thereby lifting the plug plate, changing the blocking area of the discharge port by the plug plate, and achieving the effect of changing the discharge port flow. The structure is simple, the cost is low, no extra space is occupied, and it is relatively hidden and beautiful.
[0009] The technical solution of the utility model is further described in detail below through the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solution of the utility model is further described below through the accompanying drawings and embodiments.
[0015] Example
[0016] like Figure 1 and Figure 2 As shown, a hopper with a discharge port flow control device comprises a body 1, a discharge port 2 is arranged at the bottom of the side wall of the body 1, and a flow control device is arranged on the discharge port 2. Right-angle fixing plates 9 protruding outward are arranged on the side walls of the body 1 on both sides of the discharge port 2, and a discharge pipe 11 is arranged between the two right-angle fixing plates 9, and the front end surface of the discharge pipe 11 covers the discharge port 2.
[0017] The flow control device includes a plug plate 3, an adjusting rod 7 and an adjusting plate 4. The plug plate 3 is arranged at the back of the discharge port 2, and the plug plate 3 is located between the discharge port 2 and the front end surface of the discharge pipe 11. When the plug plate 3 rises or falls, the shielding area of the discharge port 2 can be changed, so as to achieve the effect of changing the flow of the discharge port 2.
[0018] A horizontal connecting plate 10 is vertically arranged on the top of the plug board 3, and the center of the top surface of the horizontal connecting plate 10 is movably connected to the middle of the adjusting rod 7 through a right-angle connecting plate 8, and the horizontal connecting plate 10 and the right-angle connecting plate 8 are movably connected through long screws. The long screws can ensure that the plug board 3 is always vertical.
[0019] One end of the adjusting rod 7 is hinged to the body 1, and the other end is movably connected to the adjusting plate 4. The adjusting plate 4 is fixed to the side of the body 1 and is parallel to the plug plate 3. An arc-shaped slide groove 6 is provided on the adjusting plate 4, and an adjusting knob 5 is provided in front of the adjusting plate 4. The adjusting knob 5 is hinged to the other end of the adjusting rod 7 through a screw passing through the arc-shaped slide groove 6. Tightening the adjusting knob 5 can fix the inclination angle of the adjusting rod 7, so that the plug plate 3 is kept in a fixed position. After loosening the adjusting knob 5, the inclination angle of the adjusting rod 7 can be changed by pulling the adjusting knob 5, and the adjusting rod 7 changes the position of the plug plate 3 through the right-angle connecting plate 8.
[0020] The flow device has a simple structure, low cost, does not occupy extra space, is relatively concealed and beautiful, and can prevent the discharge port 2 from being blocked during actual use, making it easy to adjust.
[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
