Description

Technical field:

[0001] The invention relates to the technical field of material crushing, and in particular to a material crusher and a crushing method thereof. Background technology:

[0002] In current factory operations, it is often necessary to break large pieces of materials into small pieces or small-size materials for use, especially solid resins and fillers, which need to be finely crushed before use. At present, the crushing of large pieces of materials is mainly done by manual knocking, which not only generates a lot of dust and causes a poor working environment, but also has low efficiency and high cost. In addition, due to the different sizes of materials and the large differences in particle sizes, it is difficult to ensure accuracy, which cannot meet the needs of users well, and there are certain safety hazards when workers are knocking.

[0003] In response to the above problems, people began to use crushers to crush materials. However, in actual applications, it was found that some of the commonly used crushers on the market cannot directly crush materials with large particle sizes. They need to be manually crushed and then put into the crusher. Obviously, manual work will still bring about problems such as low efficiency, difficulty in controlling internal impurities, and difficulty in improving quality. Some crushers have a fixed capacity. After completing a batch of crushing operations, they need to manually take out the crushed materials and then add new materials to be crushed. Therefore, full automation cannot be achieved and the efficiency is poor. For most crushers, a small amount of material is the best for crushing. However, in actual applications, in order to increase work efficiency, the crusher is often filled, that is, it is operated at full load, resulting in uneven crushed materials and poor quality.

[0004] Therefore, it is necessary to design a material crusher and a crushing method thereof that can better meet the use requirements to solve the above problems. Summary of the invention:

[0005] The object of the present invention is to provide a material crusher and a crushing method thereof which can realize the automatic operation of material from bulk to fine particles.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0008] The inclination angles of the first receiving plate and the limiting plate are both 10° to 30°.

[0009] An adjustment plate is provided at the lower end of the material receiving pipe, and the adjustment plate cooperates with the first discharge port. The adjustment plate and the material receiving pipe are pin-connected or slidably connected, and the size of the first discharge port is adjusted by the adjustment plate.

[0010] The upper end of the material receiving pipe is tilted away from the side of the vibrating rod, so that the upper end opening of the material receiving pipe is wedge-shaped and matches the wedge-shaped feeding channel.

[0011] A second material receiving plate is also provided in the upper part of the box body, and a plurality of through holes are provided on the second material receiving plate, and the second material receiving plate is above the U-shaped material receiving plate.

[0012] A third material receiving plate is arranged on the first material receiving plate, the lower end of the vibration rod is in contact with the third material receiving plate, and the third material receiving plate is detachably connected to the first material receiving plate.

[0013] A counterweight block is also provided at the lower end of the first material receiving plate to increase the strength of the first material receiving plate.

[0014] The limiting plate is provided with two layers, and the two layers of limiting plates are fixedly connected as one through a connecting plate.

[0015] The second discharge port is a conical structure.

[0016] The box body is fixedly connected to the top of the box body through a flange.

[0017] The method for crushing materials by the above-mentioned material crusher comprises the following specific steps:

[0018] Step 1: Turn on the power switch of the vibrator, and put the material into the box from the feed inlet;

[0019] Step 2: The material first falls into the corresponding wedge-shaped feeding channel below the feeding port and enters the corresponding receiving pipe. The material that continues to be introduced moves horizontally on the U-shaped receiving plate, and then gradually fills into other wedge-shaped feeding channels inside the box body and enters the corresponding receiving pipe.

[0020] Step 3: The material entering the receiving pipe is sent to the first receiving plate through the first discharge port, and is crushed into fine materials on the first receiving plate under the action of the vibrating rod;

[0024] The beneficial effects of the material crusher and the crushing method of the present invention are as follows: the material enters the interior of the box from the feed port, and is sent to the first receiving plate through the feeding channel, and then is crushed by the vibrating rod, thereby realizing the continuous operation of fully automatic crushing of the material, which greatly improves the work efficiency. During the crushing operation, the material jumps under the action of the vibrator, and is crushed under the jumping vibrating rod at the same time, so that high-quality fine material can be obtained, and the quality of the crushing operation is further improved, and finer materials can be obtained, which is beneficial to the quality improvement of high-performance products and ultimately improves the quality of the products. The crushing operation of the entire process is realized by using the vibrator, and there is no need for manual preliminary crushing, which not only reduces the workload of workers and greatly reduces the generation of dust, but also ensures the safety of workers' work. The crushed material is directly collected and used through the second discharge port, so as to avoid the dust generated by the crushing from polluting the environment, and the practicability is strong.
