A fixing plate is fixed by screws at the upper end of the electric telescopic rod. A pressing rod is arranged on the left side of the electric telescopic rod and is fixed by screws at the lower end of the fixing plate.

[0004] However, in the prior art, during the operation of the crusher, if the feeding device quickly feeds a large amount of raw materials into the crusher, it is extremely easy to cause a blockage phenomenon. Such a blockage will not only cause the crusher to work smoothly, resulting in the retention of materials and inability to be crushed in time, but also due to the excessive accumulation of raw materials, the blades inside the crusher will bear an abnormally increased load, thereby accelerating the wear of the blades. In addition, the blockage will also exacerbate the vibration of the crusher and generate greater noise, which has an adverse impact on the stable operation of the equipment and the surrounding environment. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem in the prior art that the entry of a large amount of raw materials will cause the blades to bear an abnormally increased load, thereby accelerating the wear of the blades, and to propose a feeding mechanism of a crusher.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A feeding mechanism of a crusher includes a feeding table. A plurality of sliding rods are fixedly connected to one side of the drying table. A feeding plate is slidably connected to the surface of the sliding rods. A storage mechanism is installed on the top of the feeding table, and a pushing mechanism is installed on the top of the feeding table.

[0007] The stock storage mechanism includes a stock storage rack, on the inner side of which a feeding plate is slidably connected.

[0008] The material pushing mechanism includes a material pushing plate, in the center of one side of which a reciprocating plate is fixedly connected, and a driving hole is formed in the center of the reciprocating plate.

[0009] Preferably, a driving motor is fixedly connected to the bottom of the feeding table, and a driving gear is fixedly connected to the output end of the driving motor.

[0010] Preferably, a driven gear is meshed and connected to one side of the driving gear, and the driven gear is rotatably connected to the bottom of the feeding table.

[0016] 1. In the present utility model, the raw materials are accumulated to push the feeding plate, driving the movable rod, and then pushing the movable plate, stretching the tension spring to store energy. The tension spring reacts to push the movable plate, enabling the feeding plate to extrude the raw materials to help them be compacted and positioned. The material pushing plate reciprocates under the drive of the motor, pushing the raw materials to slide into the pulverizer along the feeding plate. After the feeding plate completes the pushing, the tension spring exerts force again to push the feeding plate backward to prepare for pushing the next raw material. This intermittent feeding ensures continuous supply, avoids accumulation and blockage, and can also ensure the uniform and normal pulverizing effect of the pulverizer.

[0017] 2. In the present utility model, the driving motor drives the driving gear at a constant speed, and the power is stably transmitted to the driven gear through gear transmission. The rotation of the driven gear drives the crank to perform circular motion, driving the driving rod to slide in the hole, pushing the reciprocating plate to reciprocate periodically, and the feeding plate moves along a predetermined direction accordingly to push out the raw materials. The control screw rod is used to adjust the position of the feeding plate to achieve precise feeding. The sliding rod provides stable guidance for the feeding plate, reduces friction, and ensures smooth sliding of the raw materials. This design improves the feeding flexibility, enhances the stability and reliability of the system, and realizes efficient feeding. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to more clearly understand the above objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0024] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0025] Embodiment 1: As Figure 1 - Figure 3As shown in the figure, the utility model provides a feeding mechanism for a crusher, which includes a feeding table 1. A plurality of sliding rods 7 are fixedly connected to one side of the drying table. A feeding plate 3 is slidably connected to the surface of the sliding rods 7. A material storage mechanism 2 is installed on the top of the feeding table 1, and a pushing mechanism 4 is installed on the top of the feeding table 1;

[0026] The material storage mechanism 2 includes a material storage rack 27. A feeding plate 24 is slidably connected to the inner side of the material storage rack 27. A movable rod 23 is fixedly connected to the center of one side of the feeding plate 24. One end of the movable rod 23 penetrates through the material storage rack 27, and a moving plate 21 is fixedly connected to one end of the movable rod 23. Second fixing rods 26 are fixedly connected to both sides of the moving plate 21. First fixing rods 25 are fixedly connected to both sides of the material storage rack 27. A tension spring 22 is installed between the first fixing rod 25 and the second fixing rod 26;

[0027] The pushing mechanism 4 includes a pushing plate 42. A reciprocating plate 41 is fixedly connected to the center of one side of the pushing plate 42. A driving hole 411 is opened in the center of the reciprocating plate 41.

[0028] The effect achieved by the entire embodiment is that during the feeding operation, first, a large amount of raw materials are orderly stacked inside the material storage rack 27, which ensures the stable supply of raw materials. As the raw materials continue to accumulate, they are transmitted to the movable rod 23 through the feeding plate 24, driving them to move together.

[0029] The movement of the movable rod 23 further promotes the displacement of the moving plate 21. As a connecting component, the second fixing rods 26 on both sides of the moving plate 21 are closely matched with the first fixing rods 25 fixedly installed on the machine frame, gradually stretching the tension spring 22 to make it in a tight stretched state. The stretching of the tension spring 22 not only stores energy but also provides the necessary power reserve for the subsequent feeding process.

[0030] When the tension spring 22 is stretched to a certain extent, it will act in the opposite direction to push the moving plate 21 to move in the reverse direction. This reverse movement is transmitted to the feeding plate 24 through the movable rod 23, enabling the feeding plate 24 to closely adhere to and squeeze the stacked raw materials. This squeezing effect helps to compact and position the raw materials.

[0031] Next, the pushing plate 42 is driven by a driving motor 48, and the pushing plate 42 realizes a reciprocating motion. This reciprocating motion enables the pushing plate 42 to periodically contact and push the raw materials, allowing the raw materials to smoothly slide inside the feeding plate 3 and finally enter the crusher for processing.

[0032] After the feeding plate 3 successfully transfers the previous raw material into the crusher, the elastic force of the tension spring 22 comes into play again. It pushes the movable rod 23 and the feeding plate 24 backward to prepare for the pushing of the next raw material. As the feeding plate 24 moves, the next raw material is pushed towards the starting position of the feeding plate 3, waiting for the next push. This intermittent feeding method not only ensures the continuous supply of raw materials but also avoids the problems of excessive accumulation and blockage of raw materials.

[0033] Embodiment 2: As Figure 3 and Figure 4 shown, a driving motor 48 is fixedly connected to the bottom of the feeding table 1, and the output end of the driving motor 48 is fixedly connected with a driving gear 46. A driven gear 47 is meshed and connected to one side of the driving gear 46, and the driven gear 47 is rotatably connected to the bottom of the feeding table 1. The top of the driven gear 47 is fixedly connected with a crank 44, and one side of the top of the crank 44 is fixedly connected with a driving rod 45. The driving rod 45 is slidably connected to the driving hole 411, and the top of the driving rod 45 is fixedly connected with a baffle 49. One side of the feeding table 1 is rotatably connected with a control lead screw 6, and the control lead screw 6 is threadedly connected to the feeding plate 3. One side of the pushing plate 42 is fixedly connected with a limiting plate 43, and the limiting plate 43 is slidably connected to the guiding hole 5.

[0034] The overall effect achieved by this entire embodiment is that the driving motor 48 can ensure that the driving gear 46 rotates at a constant angular velocity. Utilizing the principle of gear transmission, the power of the motor is efficiently and stably transmitted to the driven gear 47. As the driven gear 47 rotates, the crank 44 begins its unique circular motion. During the rotation of the crank 44, it drives the driving rod 45 to slide within the driving hole 411 and exerts a force on the reciprocating plate 41. Driven by the driving rod 45, the reciprocating plate 41 performs a periodic reciprocating motion. By directly acting on the pushing plate 42, the pushing plate 42 can move along a predetermined direction to gradually push out the raw materials accumulated in the designated area.

[0035] By adjusting the rotation direction and angle of the control lead screw 6, the position of the feeding plate 3 can be accurately controlled. In addition, the arrangement of multiple sliding rods 7 not only provides stable guidance for the movement of the feeding plate 3 but also reduces the frictional resistance during the movement, enabling the raw materials to slide more smoothly to the designated position. This design not only improves the flexibility of feeding but also enhances the stability and reliability of the entire system.

[0036] The usage method and working principle of this device: During the feeding operation, most of the raw materials are first stacked inside the storage rack 27. As the raw materials continue to accumulate, it will cause the feeding plate 24 to drive the movable rod 23 to move together, thereby pushing the moving plate 21. The second fixed rods 26 on both sides of the moving plate 21 cooperate with the first fixed rod 25 to pull the tension spring 22, putting it in a stretched state.

[0037] The elastic force of the tension spring 22 acts in the opposite direction, causing the moving plate 21 to drive the movable rod 23 to move in the reverse direction. The movable rod 23 then pushes the feeding plate 24 to move in the direction of the raw material accumulation, thereby squeezing the raw materials.

[0038] Subsequently, driven by the drive motor 48, the driving gear 46 starts to rotate, and transmits the power to the driven gear 47 through the meshing action. The rotation of the driven gear 47 drives the crank 44 to perform a circular motion with the center of the driven gear 47 as the center. The movement of the crank 44 further drives the drive rod 45 to slide within the drive hole 411, realizing the reciprocating movement of the reciprocating plate 41. This movement is transmitted to the pusher plate 42 through the reciprocating plate 41, enabling it to move forward and push out the accumulated raw materials.

[0039] The pushed raw materials slide inside the feeding plate 3 and finally enter the interior of the crusher. When the feeding plate 3 completes the pushing of one raw material, the elastic force of the tension spring 22 comes into play again, pushing the movable rod 23 and the feeding plate 24 forward to push out the next raw material from the storage rack 27, realizing intermittent feeding.

[0040] In addition, in order to more flexibly adapt to raw materials of different sizes, the position of the feeding plate 3 can be adjusted by controlling the lead screw 6. At the same time, the setting of multiple slide rods 7 not only facilitates the movement of the feeding plate 3, but also helps the raw materials to slide smoothly during the feeding process.

[0041] The above description is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
