Description

Technical Field

[0001] This utility model belongs to the technical field of feeding equipment, and in particular, it is a feeding device for a coal gangue hollow brick sintering kiln. Background Technology

[0002] Hollow bricks are commonly used in non-load-bearing parts. During their production, coal gangue and cement are added. After the raw materials are thoroughly mixed, they are pressed into shape using hydraulic equipment. Because a large number of hollow bricks are formed, pallets are needed to support them for centralized transport. Existing feeding devices use multiple adjustable pallets to prevent the freshly fired hollow bricks from being deformed by pressure, ensuring the device's transport capacity and facilitating loading and unloading. While this ensures transport capacity to some extent, adjusting the pallets requires rotating multiple screws to adjust their position, making the adjustment time-consuming and labor-intensive.

[0003] A search revealed a Chinese patent document (authorization announcement number CN220649115U), which discloses a feeding device for a coal gangue hollow brick sintering kiln, relating to hollow brick feeding technology. The device includes a pallet body with a hidden frame on its bottom surface. This invention, through the coordinated use of the hidden frame, support rod, first threaded fixing hole, and fourth threaded fixing hole, facilitates the rotation and storage of the support rod when the pallet body is not in use, retracting it into the hidden frame. This reduces the storage space required when the pallet body is not in use, making it easier to store. When the pallet body is in use, the worker can simply rotate and unfold the support rod from the hidden frame. While this patent ensures the device's transport capacity to a certain extent, adjusting the pallet requires rotating multiple screws to adjust its position, making the adjustment time-consuming and labor-intensive.

[0011] Preferably, the end of the movable rod away from the movable block is hinged to a support plate with an anti-slip pad.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0013] This feeding device for a coal gangue hollow brick sintering kiln benefits from the design of a stepper motor and adjustment components. By starting the stepper motor, the drive shaft rotates, which in turn rotates the winding roller, allowing multiple pallets to be adjusted from top to bottom. The adjustment of the pallets moves the mounting box, which in turn moves the slider and adjustment rod in conjunction, thus enabling the multiple pallets to be opened and closed. Compared to existing devices that require manual adjustment by rotating multiple screws, this device can adjust automatically, making pallet adjustment more time-saving and labor-saving. Furthermore, the design of the adjustment components allows for rotational movement and ensures the stability of the device during loading and unloading.

[0014] The feeding device for the coal gangue hollow brick sintering kiln can automatically adjust the pallet, making the pallet adjustment operation more time-saving and labor-saving. Attached Figure Description

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs. Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail; however, where appropriate, such techniques, methods, and equipment should be considered part of the specification. The proportions of the components in the accompanying drawings are for reference only and can be adjusted to a certain extent according to the actual use.

[0027] Examples, such as Figures 1 to 6As shown, an adjustment assembly 3 is installed at the bottom of the base 1, and a U-shaped mounting bracket 2 is fixedly connected to the top of the base 1. Multiple pallets 5 for transporting coal gangue hollow bricks are provided on the inner side of the mounting bracket 2. The specific number of pallets 5 depends on the actual situation. A mounting box 4 is fixedly connected to the bottom of each pallet 5. A guide rod 14 is fixedly connected to the inner side of the mounting box 4. Two symmetrical sliders 15 are slidably connected to the outer periphery of the guide rod 14. An adjustment rod 12 is hinged to the bottom of each slider 15, and a mounting plate 13 is hinged to the end of the adjustment rod 12 away from the slider 15. The mounting plate 13 at the top and the bottom... The pallets 5 are connected from top to bottom, and the mounting plate 13 at the bottom is fixedly connected to the base 1. The mounting box 6 is fixedly connected to the top of the mounting frame 2. By starting the stepper motor 7, the take-up roller 17 is driven to take up the material, thereby enabling multiple pallets 5 to unfold. The pallets 5 are easy to adjust, making it convenient for workers to load and unload materials. The inner side of the mounting box 6 is rotatably connected to the drive shaft 16. The side of the mounting box 6 is equipped with a stepper motor 7 that provides adjustment power to the drive shaft 16. Two take-up rollers 17 are installed on the outer periphery of the drive shaft 16, and the outer periphery of the take-up rollers 17 is connected and fixed to the pallet 5 at the top through a connecting rope.

[0028] Each side of the tray 5 is fixedly connected to a movable block. One end of the movable block passes through the limiting groove on the side of the mounting frame 2 and is fixedly connected to a positioning box 9. The side of the mounting frame 2 is fixedly connected to a limiting plate 8 with positioning holes. The inside of the positioning box 9 is fixedly connected to two return springs 19. The return springs 19 are designed to be installed and used only when there are a small number of trays 5. When there are a large number of trays 5, the return springs 19 are not needed, which makes it easier for the staff to adjust. One end of the two return springs 19 is fixedly connected to a linkage plate 18 that is connected to the inner wall of the positioning box 9. The side of the linkage plate 18 is fixedly connected to an adjustment plate 11 through the positioning box 9 via a connecting rod. The side of the adjustment plate 11 is fixedly connected to two positioning rods 10. The design of multiple positioning rods 10 is used in conjunction with the positioning holes.

[0029] The adjustment assembly 3 includes multiple movable wheels 31 installed at the bottom of the base 1, a lead screw 33 rotatably connected to the inner side of the base 1, and a drive motor 32 installed on the side of the base 1 to provide adjustment power for the lead screw 33. The lead screw 33 has a two-section design and can drive two movable blocks 34 to move in opposite directions. The outer circumference of the lead screw 33 is threadedly connected to two movable blocks 34, and the bottom end of the movable blocks 34 is hinged to a movable rod 35. The end of the movable rod 35 away from the movable blocks 34 is hinged to a support plate 36 with an anti-slip pad. The anti-slip pad design can increase the friction between the support plate 36 and the ground.

[0030] Both drive motor 32 and stepper motor 7 are conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. Both are controlled by remote control switches. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail. The scale of the attached drawings is for reference only and can be adjusted to a certain extent according to the actual use.

[0031] Working principle

[0032] The feeding device for the coal gangue hollow brick sintering kiln starts the drive motor 32 to drive the lead screw 33 to rotate according to the actual situation. The rotation of the lead screw 33 drives the movable rod 35 at the bottom of the movable block 34 to move together, so that the support plate 36 contacts the ground to ensure the stability of the device during use. When feeding, the feeding operation is carried out from top to bottom. After the top support plate 5 is fed, the stepper motor 7 is started to drive the winding roller 17 on the outer periphery of the drive shaft 16 to rotate, thereby driving the top support plate 5 to move upward. During the adjustment process, the adjustment plate 11 is pulled to drive the positioning rod 10 to disengage from the positioning hole, so that the feeding operation can be carried out in sequence. Conversely, the unloading shrinkage effect can be achieved. After adjustment, the tension on the adjustment plate 11 is released, and the positioning rod 10 is inserted into the positioning hole under the force of the return spring 19.
