Abstract
Description
Technical Field
[0001] This utility model belongs to the field of unloading valve technology, specifically a wear-resistant unloading valve. Background Technology
[0002] During the material feeding process, materials are often fed by their own weight. However, since the weight of the material is constant, the feeding speed is generally fixed. This fixed feeding speed is difficult to adapt to different production environments and cannot be adjusted according to actual conditions, which can easily affect subsequent work. Therefore, it is necessary to propose a discharge valve that is easy to adjust the feeding speed to solve the above problems. Utility Model Content
[0003] To overcome the above-mentioned defects, this utility model provides a wear-resistant unloading valve, which solves the problem that during the material unloading process, the material is often unloaded by its own gravity. However, since the material's own gravity is always constant, the material unloading speed is generally fixed. This fixed unloading speed is difficult to adapt to different production environments, and it is inconvenient to adjust the unloading speed according to the actual situation, which can easily affect subsequent work.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a wear-resistant unloading valve, comprising a housing, a fixed plate fixedly connected to one side of the housing, two electric push rods fixedly connected to the fixed plate, a movable plate fixedly connected to the output end of the two electric push rods, a material blocking plate fixedly connected to the bottom of the movable plate, a fixed support column fixedly connected inside the housing, and an adjusting screw rotatably connected to the housing via a bearing;
[0005] A moving plate is threaded onto the adjusting screw. Two connecting rods are rotatably connected to the top of the moving plate. A material guide plate is rotatably connected to the top of the two connecting rods. The material guide plate is made of high manganese steel plate. Two fixing rods are fixedly connected to the bottom of the inner wall of the box. The material guide plate is rotatably connected to the top of the two fixing rods.
[0006] As a further embodiment of this utility model: the material blocking plate is located on one side of the box body, and a discharge port is provided on one side of the box body.
[0007] As a further embodiment of this utility model: the fixed support column passes through the moving plate, and the moving plate is slidably connected to the fixed support column.
[0008] As a further embodiment of this utility model: a support limiting plate is fixedly connected inside the box, and the adjusting screw is rotatably connected to the support limiting plate through a bearing.
[0009] As a further embodiment of this utility model: the fixed support column is fixedly connected to the support limiting plate, and a material placement hopper is fixedly connected to the top of the box.
[0010] As a further embodiment of this utility model: an external adjustment knob is fixedly connected to one end of the adjustment screw, and the external adjustment knob has several grooves.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This wear-resistant discharge valve, through the configuration of a material guide plate, adjusting screw, moving plate, connecting rod, and fixed rod, allows for adjustment of the material guide plate angle. Rotating the external adjusting knob drives the adjusting screw to rotate. Since the moving plate is threaded onto the adjusting screw, its rotation causes the moving plate to move. The moving plate then pulls one side of the material guide plate downwards via the connecting rod. Because the material guide plate is rotatably connected to the tops of the two fixed rods, its downward movement causes it to rotate around the fixed rods, thus allowing for forward adjustment of the material guide plate angle. Conversely, rotating the external adjusting knob in the opposite direction causes the adjusting screw to rotate in the opposite direction, resulting in reverse movement of the moving plate. As the moving plate moves back to its initial position, it pushes one side of the material guide plate upwards via the connecting rod, causing it to rotate around the fixed rods in the opposite direction, thus allowing for reverse adjustment of the material guide plate angle. This discharge valve allows for convenient adjustment of the material guide plate angle, enabling the adjustment of the discharge speed according to actual conditions, adapting to different production environments, and preventing disruption to subsequent operations.
[0013] 2. This wear-resistant discharge valve, equipped with an electric push rod, a material blocking plate, a material guide plate, and a discharge port, allows material to be added into the housing from the material placement hopper during use. When discharge is required, the electric push rod is activated to move the moving plate and the material blocking plate upwards. At this point, the material blocking plate no longer obstructs the material, and because the material guide plate is tilted, the material will flow out of the discharge port along the tilt direction of the material guide plate, thus completing the discharge operation. This discharge valve facilitates material discharge through the tilted material guide plate, and the automatic discharge is achieved by activating the electric push rod to move the material blocking plate upwards, improving work efficiency.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0019] like Figure 1-3 As shown, this utility model provides a technical solution: a wear-resistant unloading valve, including a housing 1, a fixed plate 3 fixedly connected to one side of the housing 1, two electric push rods 4 fixedly connected to the fixed plate 3, a movable plate 5 fixedly connected to the output end of the two electric push rods 4, a material blocking plate 6 fixedly connected to the bottom of the movable plate 5, the material blocking plate 6 being located on one side of the housing 1, and a discharge port 11 being opened on one side of the housing 1.
[0020] A fixed support column 9 is fixedly connected inside the housing 1. Because of the fixed support column 9, when the moving plate 12 moves, the moving plate 12 will slide on the fixed support column 9. The fixed support column 9 can limit and guide the moving plate 12, improving the stability and accuracy of the movement of the moving plate 12. The fixed support column 9 passes through the moving plate 12, and the moving plate 12 is slidably connected to the fixed support column 9. An adjusting screw 8 is rotatably connected to the housing 1 through a bearing. The moving plate 12 is threadedly connected to the adjusting screw 8. Two connecting rods 14 are rotatably connected to the top of the moving plate 12.
[0021] Material guide plates 15 are rotatably connected to the top of the two connecting rods 14. Because the material guide plates 15 are provided and are designed to be inclined, the material will be discharged from the outlet 11 along the inclined direction of the material guide plates 15, thus facilitating the discharge. The material guide plates 15 are made of high manganese steel plates. The material guide plates 15 need to rub against the material frequently. Since the material guide plates 15 are made of high manganese steel, which has good wear resistance, the wear resistance of the material guide plates 15 is greatly improved, and the service life of the material guide plates 15 is increased. Two fixed rods 10 are fixedly connected to the bottom of the inner wall of the box 1. A support limiting plate 7 is fixedly connected inside the box 1. Because the support limiting plate 7 is provided, it can support and limit the adjustment screw 8, improving the stability of the rotation of the adjustment screw 8. The adjustment screw 8 is rotatably connected to the support limiting plate 7 through bearings.
[0022] The material guide plate 15 is rotatably connected to the top of the two fixed rods 10, the fixed support column 9 is fixedly connected to the support limit plate 7, the top of the box 1 is fixedly connected to the material placement hopper 2, and one end of the adjusting screw 8 is fixedly connected to the external adjusting knob 13. The external adjusting knob 13 has several grooves. Because the external adjusting knob 13 has several grooves, it can increase friction, make it easier for personnel to rotate the external adjusting knob 13, and improve the ease of operation.
[0023] The working principle of this utility model is as follows:
[0024] In use, materials are added into the box 1 from the material placement hopper 2. When unloading is required, the electric push rod 4 is activated to move the moving plate 5 and the material blocking plate 6 upwards. At this time, the material blocking plate 6 no longer blocks the material, and because the material guide plate 15 is in an inclined state, the material will be discharged from the discharge port 11 along the inclined direction of the material guide plate 15, thus completing the unloading work. When it is necessary to adjust the angle of the material guide plate 15, the external adjustment knob 13 is turned to drive the adjustment screw 8 to rotate. Since the moving plate 12 is threadedly connected to the adjustment screw 8, when the adjustment screw 8 rotates, the moving plate 12 will move. The moving plate 12 will pull one side of the material guide plate 15 downwards through the connecting rod 14. Since the material guide plate 15 is rotatably connected to the top of the two fixed rods 10, when one side of the material guide plate 15 moves downward, the material guide plate 15 will rotate around the fixed rod 10, thereby allowing the angle of the material guide plate 15 to be adjusted in the forward direction. When the external adjustment knob 13 is rotated in the reverse direction, causing the adjustment screw 8 to rotate in the reverse direction, the moving plate 12 will move in the reverse direction. During the process of the moving plate 12 moving in the reverse direction to the initial position, the moving plate 12 will push one side of the material guide plate 15 upward through the connecting rod 14, causing the material guide plate 15 to rotate in the reverse direction around the fixed rod 10, thereby allowing the angle of the material guide plate 15 to be adjusted in the reverse direction. The feeding speed can be adjusted by adjusting the angle of the material guide plate 15.
