[0002] Stone, as the name implies, is a rock used as a material and is widely used in engineering. In the process of stone use and processing, stone conveying equipment is usually needed to transport the stone. However, the stone conveying equipment currently used is a conveyor belt. Due to inertia and irregularity of the stone, the stone rolls down and splashes, affecting the conveying efficiency. When the stone falls into the crusher, it falls by free fall, which will cause a certain degree of damage to the crushing roller, greatly reducing the service life of the crushing roller. Utility Model Content

[0003] In view of this, the utility model provides a screw conveying device for stone processing, which can block and slow down the falling speed of materials by hingedly arranging a material baffle plate at the discharge port of the screw conveyor, thereby avoiding the problem that the stone conveying equipment used is a conveyor belt. Due to inertia and irregularity of stones, the stones roll down and splash, affecting the conveying efficiency, and when the stones fall into the crusher, they fall by free fall, which will cause a certain degree of damage to the crushing roller, greatly reducing the service life of the crushing roller.

The utility model can block and slow down the falling speed of materials by hingedly setting a baffle plate at the discharge port of the screw conveyor, thereby avoiding the use of a conveyor belt as the stone conveying equipment. Due to inertia and the irregularity of stones, the stones roll down and splash, affecting the conveying efficiency. When the stones fall into the crusher, they fall by free fall, causing a certain degree of damage to the crushing roller, greatly reducing the service life of the crushing roller.

The utility model is safer and more convenient. The baffle plate is hingedly arranged at the discharge port of the screw conveyor to block and reduce the falling speed of the material, thereby avoiding the use of a conveyor belt as the stone conveying equipment. Due to inertia and the irregularity of the stone, the stone rolls down and splashes, affecting the conveying efficiency.

The utility model can block and slow down the falling speed of the material by hingedly setting the baffle plate 300 at the discharge port 201 of the screw conveyor, avoiding the use of the stone conveying equipment as a conveyor belt, which rolls down and splashes due to inertia and irregularity of the stone, affecting the conveying efficiency, and when the stone falls into the crusher, it falls by free fall, causing a certain degree of damage to the crushing roller, greatly reducing the service life of the crushing roller.

[0019] According to one embodiment of the utility model, Figure 1 and Figure 2 As shown, the baffle plate 300 is U-shaped, and a buffer arc slope is provided at the end of the baffle plate 300. The utility model can further buffer the material falling through the baffle plate 300 through the buffer arc slope, thereby reducing the speed at which the material enters the crusher, thereby avoiding excessive impact on the crushing blades of the crusher due to excessive rising and falling speeds, thereby causing damage to the crushing blades.

[0020] According to another embodiment of the present invention, Figure 1 and Figure 3 As shown, the frame 100 is a frame structure with a lower height on the right side than on the left side. A support leg 500 is provided at the bottom of the frame 100. The purpose of this is to facilitate placing the feed port 202 of the auger conveyor 200 at a low position on the left side, and placing the discharge port 201 of the auger conveyor 200 at a high position on the right side of the bracket. In this way, the operator standing on the ground or on the horizontally placed conveyor belt can smoothly, conveniently and quickly realize the material conveying operation, thereby realizing the automatic lifting operation of the material, which is more convenient.

[0021] The lower part of the shell of the auger conveyor 200 is evenly distributed with multiple water inlets 400 connected to the cleaning machine. The purpose of this is to facilitate the cleaning operation of the conveying blades, conveying shaft and the inside of the shell of the auger conveyor 200 by using a cleaning agent, making the operation more convenient and efficient.

[0022] The auger conveyor 200 has two feed ports 202, one of which is a funnel-shaped structure, and the other is a prism-shaped box structure with an upper opening larger than a lower opening. This allows the simultaneous feeding and conveying of two materials, making the operation more convenient and efficient.

[0023] The use of the utility model:

[0024] First of all, it should be made clear that the screw conveying device involved in the utility model is mainly used for lifting and conveying materials. The utility model takes the conveying of stone as an example to explain its method of use in detail. When it is necessary to convey the stone, the feed port 202 of the crusher is placed directly below the discharge port 201 of the auger conveyor 200, and then the motor of the auger conveyor 200 is started to rotate, and then the stone is transported to the feed port 202 of the auger conveyor 200 manually or with the help of a horizontally placed conveyor belt, and then the rotation of the output shaft of the motor will drive the conveying shaft and the conveying blades on the outside of the conveying shaft to move the stone to the discharge port 201 of the auger conveyor 200. Through the action of the torsion spring, when the stone falls onto the baffle plate 300 during the falling process of the material, it will press the baffle plate 300. 00 will be tilted at a certain angle under the action of the torsion spring. At this time, the restoring elastic force of the torsion spring itself has a reverse thrust on the baffle plate 300, thereby realizing the effect of slowing down the falling speed of the material by the baffle plate 300, avoiding the crushing roller or crushing blade placed in the crusher under it in advance from being damaged due to inertia and free fall. It is safer and more convenient. The baffle plate 300 is hingedly set at the discharge port 201 of the screw conveyor to block and slow down the falling speed of the material, avoiding the use of a conveyor belt as the stone conveying equipment. Due to inertia and the irregularity of the stone, the stone rolls down and splashes, affecting the conveying efficiency. When the stone falls into the crusher, it falls by free fall, causing a certain degree of damage to the crushing roller, greatly reducing the service life of the crushing roller.

[0025] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0026] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
