Description

Technical Field

[0001] This utility model relates to the field of crusher feeding technology, specifically a crusher feeding device. Background Technology

[0002] A crusher is a device that uses a certain mechanism to crush large pieces of material into smaller pieces using one or more force application methods. It is a type of general-purpose equipment widely used in industrial production. Crushing machinery in which the content of particles larger than three millimeters in the discharge accounts for more than 50% of the total discharge volume is also called a crusher.

[0003] Chinese patent CN220345963U discloses a crusher, including a crusher base plate. A crusher housing is fixedly installed on the top of the base plate. A first crushing wheel is disposed inside the crusher housing, and a first motor is disposed on one side of the first crushing wheel. Slide grooves are provided at the front and rear of the crusher housing. A second crushing wheel is movably installed inside the crusher housing, and both sides of the second crushing wheel are slidably mounted on the slide grooves of the crusher housing via sliders. By incorporating a crusher base plate, a first crushing wheel, a second crushing wheel, a second motor, and a hydraulic telescopic rod, this design effectively solves the problem that most existing crushers are dual-wheel crushers, where the positions of the two crushing wheels are mostly fixed, making it impossible to adjust the gap between the crushing wheels according to needs, resulting in poor overall applicability of the crusher.

[0004] However, the crusher cannot adjust the material feeding speed as needed, and the material cannot be evenly distributed during the crushing process. This may lead to material accumulation, causing the crusher to overload, and long idle running time, which reduces crushing efficiency. Therefore, a crusher feeding device is needed. Utility Model Content

[0005] The purpose of this invention is to provide a crusher feeding device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a crusher feeding device, comprising a crusher body, a feeding box, and a feed hopper. A pretreatment mechanism is provided inside the feed hopper, and a feeding mechanism is provided inside the feeding box. The pretreatment mechanism includes an active crushing roller and a driven crushing roller rotatably disposed within the feed hopper. A motor is disposed at the rear of the feed hopper, and the output shaft of the motor rotatably passes through the feed hopper and is fixedly connected to the roller shaft of the active crushing roller. The feeding mechanism includes a pusher plate slidably disposed within the feed hopper. A movable frame is disposed between the crusher body and the feed hopper. A connecting rod is fixedly disposed at one end of the movable frame. One end of the pusher plate slidably passes through the feed hopper and is fixedly connected to the connecting rod. Two toothed grooves are provided on the inner side of the movable frame. A fixed plate is fixedly disposed on the crusher body, and a rotating rod is rotatably disposed on the fixed plate. A half-gear meshing with the toothed grooves is fixedly sleeved on the rotating rod. A belt drive assembly is provided between one end of the rotating rod and the output shaft of the motor.

[0007] Preferably, the roller shafts of both the active crushing roller and the driven crushing roller, at the end furthest from the motor, rotate through the feed box and are meshed and driven by a gear transmission assembly.

[0008] Preferably, a mounting bracket is fixedly provided on the rear side of the feeding box, and the motor is mounted on the mounting bracket by bolts.

[0009] Preferably, the top of the crusher body and the bottom of the feed box are both fixedly provided with slide rails, the slide rails are provided with slide grooves, and the movable frame is fixedly provided with a slider that is slidably connected to the slide groove.

[0010] Preferably, a slide rod is fixedly installed in the slide groove, the slide block is slidably connected to the slide rod, and a spring is sleeved on the slide rod and fixedly installed between the slide block and the slide groove.

[0011] Preferably, the feeding box is located above the crusher body, a feeding pipe is connected between the feeding box and the crusher body, and a discharge hopper is connected to the discharge port of the crusher body.

[0012] Preferably, the feed box is located on top of the feeding box, the discharge port of the feed box is connected to the inlet of the feeding box, and a guide plate is provided on the inlet of the feed box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) The feeding device of this crusher, when the motor is working, drives the rotating rod to rotate through the belt drive assembly. The rotation of the rotating rod drives the half gear to rotate, so that the moving frame drives the pusher plate to move back and forth through the connecting rod, realizing intermittent feeding of materials, ensuring uniform distribution of materials during the crushing process, and improving crushing efficiency. When the moving frame moves, the slider slides along the surface of the sliding rod in the slide groove on the slide rail, improving the stability of the moving frame during movement. When the moving frame returns to its original position, the rebound force of the spring can provide a boosting force to the moving frame and the pusher plate, reducing the load on the motor. By adjusting the speed of the motor, the material feeding speed can be adjusted as needed.

[0015] 2) The feeding device of this crusher drives the active crushing roller to rotate through the motor. Under the transmission of the gear transmission assembly, the active crushing roller and the driven crushing roller rotate in opposite directions, so that the material in the feed box can be crushed into smaller pieces in advance, thereby reducing the workload of the subsequent crusher body and avoiding blockage when the material enters the crusher body. At the same time, the pre-crushed material is easier to be uniformly processed by the crusher body, reducing crusher wear and energy consumption caused by uneven material size.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Combination Figures 1-5 A crusher feeding device includes a crusher body 1, a feeding box 2, and a feed box 3. The feeding box 2 is located above the crusher body 1, and a discharge pipe 5 is connected between the feeding box 2 and the crusher body 1. A discharge hopper 6 is connected to the discharge port of the crusher body 1. The feed box 3 is located on top of the feeding box 2, and the discharge port of the feed box 3 is connected to the inlet of the feeding box 2. A guide plate 4 is provided on the inlet of the feed box 3. A pre-treatment mechanism 7 is provided inside the feed box 3, and a feeding mechanism 8 is provided inside the feeding box 2.

[0027] See Figures 2-4 Furthermore, the pretreatment mechanism 7 includes an active crushing roller 701 and a driven crushing roller 702 rotatably disposed in the feed box 3. A motor 705 is disposed on the rear side of the feed box 3. The output shaft of the motor 705 rotatably passes through the feed box 3 and is fixedly connected to the roller shaft of the active crushing roller 701. The roller shafts of the active crushing roller 701 and the driven crushing roller 702 at the ends away from the motor 705 both rotatably pass through the feed box 3 and are meshed and driven by the gear transmission assembly 703. A mounting bracket 704 is fixedly disposed on the rear side of the feed box 2, and the motor 705 is mounted on the mounting bracket 704 by bolts.

[0028] Specifically, the motor 705 drives the active crushing roller 701 to rotate. Under the transmission action of the gear transmission assembly 703, the active crushing roller 701 and the driven crushing roller 702 rotate in opposite directions, so that the material in the feed box 3 can be crushed into smaller pieces in advance, thereby reducing the workload of the subsequent crusher body 1 and preventing blockage when the material enters the crusher body 1. At the same time, the pre-crushed material is more easily processed evenly by the crusher body 1, reducing crusher wear and energy consumption caused by uneven material size.

[0029] See Figures 3-5Furthermore, the feeding mechanism 8 includes a pusher plate 801 slidably disposed within the feed box 2. A movable frame 802 is disposed between the crusher body 1 and the feed box 2. A connecting rod 809 is fixedly disposed at one end of the movable frame 802. One end of the pusher plate 801 slidably passes through the feed box 2 and is fixedly connected to the connecting rod 809. Two toothed grooves 803 are provided on the inner side of the movable frame 802. A fixed plate 810 is fixedly disposed on the crusher body 1. A rotating rod 811 is rotatably disposed on the fixed plate 810. A toothed groove 803 is fixedly sleeved on the rotating rod 811 and engages with the toothed groove 803. The half gear 812 and the output shaft of the motor 705 are connected by a belt drive assembly 813. The top of the crusher body 1 and the bottom of the feed box 2 are both fixedly provided with slide rails 805. The slide rails 805 are provided with slide grooves 806. The moving frame 802 is fixedly provided with a slider 804 that is slidably connected to the slide groove 806. The slide groove 806 is fixedly provided with a slide rod 807. The slider 804 is slidably connected to the slide rod 807. The slide rod 807 is fitted with a spring 808 that is fixedly provided between the slider 804 and the slide groove 806.

[0030] Specifically, when the motor 705 is working, it drives the rotating rod 811 to rotate via the belt drive assembly 813. The rotation of the rotating rod 811 drives the half gear 812 to rotate, causing the moving frame 802 to move back and forth via the connecting rod 809 and the pusher plate 801. This achieves intermittent feeding of materials, ensuring uniform distribution of materials during the crushing process and improving crushing efficiency. When the moving frame 802 moves, the slider 804 slides along the surface of the slide rod 807 in the slide groove 806 on the slide rail 805, improving the stability of the moving frame 802 during movement. When the moving frame 802 returns to its original position, the rebound force of the spring 808 provides a boosting force to the moving frame 802 and the pusher plate 801, reducing the load on the motor 705. By adjusting the speed of the motor 705, the material feeding speed can be adjusted as needed.

[0031] In actual operation, the material flows into the feed box 3 through the guide plate 4. The motor 705 drives the active crushing roller 701 to rotate. Under the transmission action of the gear transmission assembly 703, the active crushing roller 701 and the driven crushing roller 702 rotate in opposite directions, so that the material in the feed box 3 can be crushed into smaller pieces in advance to reduce the workload of the subsequent crusher body 1.

[0032] The pre-crushed material falls into the feeding box 2 through the outlet of the feed box 3. When the motor 705 is working, it drives the rotating rod 811 to rotate through the belt drive assembly 813. The rotating rod 811 drives the half gear 812 to rotate. When the half gear 812 meshes with the tooth groove 803 near the top of the inner side of the moving frame 802, the moving frame 802 drives the pusher plate 801 to push the material in the feeding box 2 through the connecting rod 809. When the half gear 812 meshes with the tooth groove 803 near the bottom of the inner side of the moving frame 802, the moving frame 802 drives the pusher plate 801 to reset through the connecting rod 809. By repeating this process, the material can be fed intermittently, so that the pushed material falls quantitatively into the crusher body 1 through the feeding pipe 5. After being crushed by the crusher body 1, the material is discharged through the discharge hopper 6.

[0033] When the moving frame 802 moves, the slider 804 can slide along the surface of the slide rod 807 in the slide groove 806 on the slide rail 805, which improves the stability of the moving frame 802 when it moves. At the same time, when the moving frame 802 drives the pusher plate 801 to push the material, the slider 804 can squeeze the spring 808 sleeved on the slide rod 807. When the moving frame 802 returns to its original position, the rebound force of the spring 808 can provide a boosting force to the moving frame 802 and the pusher plate 801, reducing the load on the motor 705.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
