Abstract
Description
Technical Field
[0001] This invention relates to the field of sand making, specifically to a stone-throwing device for an impact sand making machine. Background Technology
[0002] In modern engineering construction, sand is one of the most important building materials. By mixing it with other materials in a certain proportion, it can form various other building materials. In addition, it plays an important role in applications such as filtration, aquaculture and landscaping, quick-dissolving agents, and catalysts. Sand is mainly produced by sand making machines. High-speed rotating stone throwers throw sand and gravel out and crush them by impacting the crushing plates, thus forming sand. The sand making machine has a double-layer structure at the feed inlet. Sand and gravel entering from the inside will fall into the inside of the stone thrower, while sand and gravel entering from the outside will fall into the outside of the stone thrower and collide with the sand and gravel thrown out by the stone thrower to crush them, thus completing the preparation of sand.
[0003] Because the sand and gravel ejected from the catapult collide with the sand and gravel outside the catapult at a 90-degree angle, their kinetic energy cannot be fully utilized for crushing, resulting in a decrease in the device's crushing effect. Furthermore, the collision between the ejected sand and gravel and the sand and gravel outside the catapult is random; often, the ejected sand and gravel directly impacts the impact plate without being completely crushed, only breaking into small particles. These particles are discharged with the sand, affecting its quality and requiring secondary crushing, increasing production difficulty and reducing sand quality. Therefore, this application proposes an impact crusher to address the aforementioned problems.
[0004] In view of the shortcomings of existing impact crushers mentioned in the background art, the present invention provides an impact crusher that has the advantage of being able to perform secondary crushing of insufficiently crushed sand and gravel, thus solving the problem that the traditional impact crusher discharges insufficiently crushed sand and gravel along with the sand, resulting in a decrease in sand quality. Summary of the Invention
[0005] The purpose of this invention is to provide an impact sand making machine stone throwing device to solve the problem of declining sand quality.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an impact crusher stone throwing device, comprising: a main body for mounting parts;
[0007] The storage box for storage is located in the middle of the bottom inside the main body;
[0008] Motors are fixedly installed on both sides of the bottom of the main body. Rotating columns are fixedly connected to the output ends of the motors on both sides.

[0031] The working principle of this invention is as follows: First, stones are placed in the first turntable 22 and evenly fall into the opening of the second turntable 23 through the grid. When there are too many stones, they fall into the openings on both sides and into the crushing disc 25 through the sliding rods 31 on both sides of the second turntable 23. Then, the power is turned on to drive the double-head motor 24 to drive the crushing disc 25 to rotate. Then, the stones are driven to undergo centrifugal motion and impact the inside of the main body 1 to complete the crushing. Then, the motors 3 on both sides drive the rotating column 5 to rotate and drive the crushing fan 6 to rotate to complete the crushing. The double-pass motor 24 drives the fifth disc 26 to rotate and then drives the sixth disc 29 to rotate. At the same time, it drives the pressing block 28 to press down to improve the crushing effect. Then, the rotating column 5 rotates and drives the toothed plate 7 to rotate. Through the interaction between the toothed plate 7 and the second gear 11, the second gear 11 is driven to rotate.
