[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0023] like Figure 1 As shown, this crusher feeding adjustment device includes a lifting structure 1, a height adjustment structure 2, and a material control structure 3; wherein the lifting structure 1 serves as the starting end of the entire device and is used to lift the material to be crushed to a certain height and then into the material control structure 3; The height adjustment structure 2 is set between the lifting structure 1 and the material control structure 3. Through its adjustment mechanism (see below for details), it can control the relative tilt angle between the two. That is, when the tilt angle between them is further increased by the height adjustment structure 2, the height of the material control structure 3 connected to the top of the material control structure 3 will be further increased, so as to correspond to the feed inlet of different sized crushers, so that the device can adapt to the feed inlet requirements of different sized crushers. The material control structure 3 is used to receive the material to be crushed conveyed from the bottom to the top by the lifting structure 1, and can control the output amount of the material to be crushed into the crusher, so as to ensure that the material will not cause blockage when entering the crusher, and can maintain a stable feeding speed, thereby effectively improving the working efficiency of the crusher.

[0024] like Figure 2 As shown, and refer to Figure 1 The lifting structure 1 further includes a conveyor 11, a feed hopper 12, and multiple pusher plates 13; specifically, the conveyor 11 is used to stably convey materials; the feed hopper 12 is preferably funnel-shaped with a wider top and a narrower bottom, and is fixed at the bottom of the conveyor 11 to guide the poured material to be crushed to fall onto the conveyor 11, and then be conveyed by the conveyor 11 to the material control structure 3 along its moving direction; Multiple pusher plates 13 are evenly distributed on the surface of the conveyor 11. More specifically, the height and spacing of the pusher plates 13 are reasonably set according to the characteristics of the material and the conveying volume. When the conveyor 11 is running, the pusher plates 13 can push the material in the feed hopper 12 forward step by step (i.e., in the direction of the highest point in the figure) until the material is sent into the material control structure 3.

[0025] In some embodiments, as shown in the figure, the conveyor 11 further includes a set of side plates 111, a liner 112, a set of rollers 113, a belt 114, and a motor 115; specifically, the set of side plates 111 are arranged at an inclined parallel to stabilize and support the entire structure of the conveyor 11. The liner 112 is horizontally fixed between a set of side plates 111 to provide a stable bearing surface for the material and prevent the material from falling during the conveying process; a set of rollers 113 are respectively installed at both ends of the side plates 111, one of the rollers 113 is coaxially connected to the motor 115, and when the motor 115 is running, it drives the roller 113 to rotate, which in turn drives the other roller 113 to rotate through the belt 114, so as to realize the cyclic operation of the belt 114; The belt 114 is fitted around a set of rollers 113 and liners 112 and moves in a cycle as the rollers 113 rotate. Since the feed hopper 12 is fixed between a set of side plates 111 and multiple pusher plates 13 are fixed at equal intervals on the outer surface of the belt 114, when the conveyor 11 is running, the belt 114 drives the multiple pusher plates 13 to move synchronously, thereby continuously and evenly pushing the material in the feed hopper 12 to the material control structure 3, and finally entering the crusher through the material control structure 3.

[0026] like Figure 3 As shown, and refer to Figure 1 The material control structure 3 further includes an inlet 31, an outlet 32, a material holding space 33, a channel 34, a baffle 35, and a control element 36; specifically, the inlet 31, the outlet 32, and the material holding space 33 are located at different positions in the channel 34, that is, the inlet 31 is located on the side of the channel 34 close to the conveyor 11, for receiving materials pushed from the conveyor 11. The outlet 32 ​​is located on the side of the channel 34 away from the conveyor 11 and corresponds to the feed inlet of the crusher so as to feed the material into the crusher; the material holding space 33 is located between the inlet 31 and the outlet 32, providing a temporary storage and buffer area for the material. The baffle 35 is rotatably connected to the material holding space 33. Its initial position makes the outlet 32 ​​fully open. When it is necessary to adjust the feed rate, the control component 36 starts to work, driving the baffle 35 to rotate and causing the other end to invade into the material holding space 33, thereby gradually reducing the opening size of the outlet 32 ​​and thus controlling the material flow rate into the crusher. The control element 36 can be an electric push rod, a hydraulic cylinder 223, or other devices that can provide stable power to ensure that the opening and closing of the baffle 35 is smooth and accurate.

[0027] In some embodiments, such as Figure 4 As shown, the control component 36 further includes a wheel set 361, a bracket 362, and a linear module 363; specifically, the wheel set 361 rolls in contact with the top of the baffle 35, so that the baffle 35 moves and rotates with the wheel set 361, causing the other end of it away from the rotation connection point to move into the material holding space 33, thereby partially blocking the outlet 32, thus changing the size of the outlet 32. The bracket 362 is connected to the wheel set 361 and extends through a groove opened at the top of the channel 34. The groove provides a specific track for the movement of the bracket 362, enabling it to move in a predetermined direction. The linear module 363 is connected to the support 362 through a transmission. The linear module 363 drives the support 362 to move through its own linear motion, which in turn causes the wheel set 361 on the support 362 to move towards the rotation connection point between the baffle 35 and the material holding space 33. This achieves precise control of the rotation angle of the baffle 35, and ultimately achieves the purpose of adjusting the opening size of the outlet 32 ​​and controlling the flow rate of material entering the crusher.

[0028] It should be noted that the linear module 363 includes components such as a motor 115, a lead screw, a nut slide, and a guide rail. The motor 115 serves as a power source, driving the lead screw to rotate. The nut slide cooperates with the lead screw, moving linearly along the lead screw as it rotates. The guide rail provides stable guidance for the linear movement of the nut slide, ensuring that the nut slide can move accurately along the predetermined direction. Since the nut slide is connected to the bracket 362, it transmits its own linear movement to the bracket 362, causing the wheel set 361 on the bracket 362 to move from the outlet 32 ​​to the inlet 31 within the material holding space 33. As the wheel set 361 moves, it pushes against the baffle 35, causing the baffle 35 to rotate downward about the rotation connection point within the material holding space 33, thereby reducing the opening size of the outlet 32.

[0029] In some embodiments, continue as follows Figure 4 As shown, and refer to Figure 3 The material control structure 3 also includes a set of reset members that can gradually cancel the top support force applied to the baffle 35 when the wheel set 361 moves towards the initial point through the linear module 363, while driving the other end of the baffle 35 to rotate towards the initial point to expand the opening size of the outlet 32. Thus, under the action of the reset members, the baffle 35 is kept in contact with the wheel set 361 at different moving positions. Each set of reset components further includes a tension spring 37. Specifically, one end of the tension spring 37 is securely hooked to a pre-set hook point on the top wall of the material storage space 33 via a hook, and the other end is connected to the top of the baffle 35 via the same hook structure. When the wheel assembly 361 moves toward the rotation connection point of the baffle 35, the tension spring 37 gradually stretches, generating an upward pulling force. This pulling force acts on the baffle 35. When the wheel assembly 361 resets, the tension spring 37 continuously contracts, causing the other end of the baffle 35 to rotate toward the initial point, thereby gradually expanding the opening size of the outlet 32 ​​until it returns to the initial state. During this process, the tension spring 37, with its own elastic characteristics and the travel length of the wheel assembly 361, ensures that the opening size of the outlet 32 ​​is within a specified range, thus ensuring that the crusher feed adjustment device can adjust the feed rate according to actual needs. Meanwhile, the elasticity of the tension spring 37 ensures that the baffle 35 remains in contact with the wheel set 361 during the movement of the wheel set 361, thereby ensuring the stability of the feed adjustment.

[0030] like Figure 5 As shown, the height adjustment structure 2 further includes a set of support legs 21 and a brake 22; specifically, the lower end of the set of support legs 21 is supported on the ground, and the upper end rotates with the top of the conveyor 11 (the top of the side plate 111). The rotational connection allows the conveyor 11 to be tilted relative to the support legs 21 at a certain angle to adjust the height of the material control structure 3. Braking component 22 is located between the conveyor 11 and the support leg 21. By adjusting the length or tightness of the braking component 22, the tilt angle between the conveyor 11 and the support leg 21 can be controlled, thereby achieving precise adjustment of the tilt height of the conveyor 11 and the height of the material control structure 3. The height adjustment structure 2 allows the crusher's feed adjustment device to more flexibly adapt to the feed height requirements of different working scenarios, improving the equipment's versatility and practicality. Based on the above, the inlet 31 side of the channel 34 is rotatably connected between the top ends of a set of side plates 111, and the bottom side of the outlet 32 ​​of the channel 34 is connected to a set of support legs 21 through the connecting rod frame 4; the connecting rod frame 4 plays a stabilizing support role, ensuring that the channel 34 maintains a relatively stable position during the tilt adjustment of the conveyor 11, and will not sway excessively or shift position due to the tilt of the conveyor 11. The linkage 4 includes two parallel connecting rods. One end of each connecting rod is rotatably connected to the bottom side of the outlet 32 ​​of the channel 34, and the other end is connected to a crossbar. The two ends of the crossbar are fixedly connected to a set of legs 21. In some embodiments, such as Figure 5 As shown, the braking component 22 further includes a first rod 221, a second rod 222, and a set of hydraulic cylinders 223. Specifically, the first rod 221 is fixed between the bottoms of a set of side plates 111; the second rod 222 is fixed between a set of support legs 21; and the set of hydraulic cylinders 223 is connected between the first rod 221 and the second rod 222 by a retaining ring. Through the extension and retraction of the hydraulic cylinders 223, the relative distance between the first rod 221 and the second rod 222 can be precisely controlled, thereby achieving precise adjustment of the inclination between the conveyor 11 and the support legs 21. The height of the material control structure 3 can be adjusted by adjusting the inclination.

[0031] In some embodiments, continue as follows Figure 5 As shown, the height adjustment structure 2 also includes a first wheel 23 fixed to the bottom of a set of side plates 111, and a second wheel 24 fixed to the bottom of a set of support legs 21. The arrangement of the first wheel 23 and the second wheel 24 facilitates the movement of the entire device. When it is necessary to change the working position of the device, the first wheel 23 and the second wheel 24 can be rolled by pushing the device, thereby easily moving the device to the target location and reducing the labor intensity of manual handling. At the same time, the arrangement of the first wheel 23 and the second wheel 24 also reduces the moving resistance for adjusting the inclination of the conveyor 11 and the height of the material control structure 3, making the adjustment process smoother.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
