Description

Technical Field

[0001] The utility model relates to the technical field of material conveying of a brick press, in particular to a material conveying mechanism of a brick press. Background Art

[0002] Brick making machines generally use stone powder, fly ash, slag, ore slag, crushed stones, sand, water, etc. as raw materials. New wall materials such as autoclaved fly ash bricks, autoclaved lime sand bricks, and aerated concrete products are efficiently produced using fly ash, slag, stone powder, desulfurized ash, ore slag, coal gangue, phosphogypsum, tailing sand, etc. When making bricks, plasticity is emphasized. The higher the plasticity of the raw materials, the better the quality of the bricks produced. Plasticity is directly proportional to the size of the raw materials. The higher the plasticity of the raw materials, the smaller the size should be. Therefore, the raw materials need to be crushed.

[0003] A Chinese patent with the publication number CN212636106U and the name of an automatic light brick making machine raw material conveying device includes a bottom plate. One side of the top of the bottom plate is welded with a pair of vertically upward fixed brackets, and on the side of the top of the bottom plate far from the fixed brackets, a pair of vertically upward hydraulic rods are welded. A roller is welded between the middle of the fixed brackets and the top of the hydraulic rods through bearings, and a feeding hopper is welded on the top of the fixed brackets. This patent solves the problem of raw material crushing, but the crushing is not sufficient, and at the same time, it lacks the function of screening the materials, resulting in the problem that the sizes of the raw materials are different and it is difficult to ensure the quality of the bricks produced. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Figures 1 - 4 A material conveying mechanism of a brick press includes a bottom platform 1. On one side above the bottom platform 1, two fixed rods 2 are fixedly connected. Above the bottom platform 1, an inclined screening mechanism is provided. On both sides of the lower end of the screening mechanism, a first rotating shaft 8 is fixedly connected respectively. The two first rotating shafts 8 are fixedly connected to the fixed rods 2. On both sides of the upper end of the screening mechanism, fixed blocks 5 are fixedly connected. Below the two fixed blocks 5, a vibration mechanism is connected. On the other side above the bottom platform 1, two fixing plates 9 are fixedly connected. Between the two fixing plates 9, a stirring frame 12 is fixedly connected. Inside the stirring frame 12, a stirring and crushing mechanism is provided. Above the stirring frame 12, a feeding port 13 is welded. The feeding port 13 is in the shape of being large at the top and small at the bottom, and feeds in from the large opening when feeding.

[0023] In the present utility model, the screening mechanism includes a screening frame 6. The two first rotating shafts 8 are respectively fixedly connected to both sides of the screening frame 6. The two first rotating shafts 8 enable the screening mechanism to move up and down. On the inner bottom of the screening frame 6, a screening mesh 16 is provided. The screening mesh 16 is detachable and replaceable to meet the requirements of different raw material sizes. At the bottom of the screening frame 6, a collection frame 7 is fixed. The collection frame 7 can collect the screened raw materials. On one side of the collection frame 7, a vibration motor 15 is provided. The vibration motor 15 can drive the screening mechanism to vibrate.

[0024] The vibration mechanism includes a vibration spring 4 fixedly connected to the lower end of the fixed block 5. The lower end of the vibration spring 4 is fixedly connected to a fixed column 3. The bottom end of the fixed column 3 is fixedly connected to the upper end of the bottom platform 1. When the screening mechanism is driven by the vibration motor 15, the vibration effect will be more obvious under the action of the vibration spring 4.

[0025] The stirring and crushing mechanism includes two second rotating shafts 11 arranged inside the stirring frame 12. Stirring rollers 14 are fixedly sleeved on both of the two second rotating shafts 11. Thread grooves are dug on the surface of the stirring rollers 14. The two stirring rollers 14 rotate relatively to crush the raw materials. The ends of the two second rotating shafts 11 penetrate through the stirring frame 12 and are rotatably connected to the stirring frame 12. Gear 10 is fixedly sleeved on the end of each of the two second rotating shafts 11, and the gear 10 is located outside the stirring frame 12. The two gears 10 mesh with each other. The diameters of the two gears 10 are the same, and the teeth of the gear 10 are helical teeth. A motor 17 is provided on the side wall of the stirring frame 12. The output shaft of the motor 17 is connected to the end of one of the second rotating shafts 11. When the motor 17 drives one of the second rotating shafts 11, the other second rotating shaft 11 will be driven under the action of the two gears 10, causing the two stirring rollers 14 to rotate.

[0026] When the present utility model is in use, the worker first pours the raw materials into the feeding port 13, and then starts the motor 17. The motor 17 drives the two gears 10, and the two gears 10 rotate relative to each other to drive the two stirring rollers 14. The two stirring rollers 14 squeeze each other to crush the raw materials. The crushed raw materials fall into the screening frame 6 below through the stirring frame 12. Then, the vibration motor 15 is started. The screening frame 6 and the collection frame 7 vibrate up and down under the action of the vibration springs 4. The raw materials in the screening frame 6 are screened by the screening mesh 16, and the screened raw materials fall into the collection frame 7 below. The raw materials collected by the collection frame 7 can be used for making bricks. The raw materials that do not fall into the collection frame 7 below can be collected from the low-end outlet of the screening frame 6 and put into the device again for secondary crushing and screening.
