Description

Technical Field

[0001] The invention relates to the field of sand making equipment, and in particular to a double-roller sand making machine with a shaping function. Background Art

[0002] Roller sand making machine, also known as roller crusher or double roller crusher, is a common crushing equipment, widely used in the production of sand and gravel in the fields of construction, roads, bridges, water conservancy, etc. Its working principle is to use two crushing rollers rotating in opposite directions to sandwich the material in the middle, and crush the material into sand and gravel aggregates through the friction and extrusion force between the crushing rollers and the material. During the crushing process, the material is repeatedly squeezed and ground, gradually reducing the particle size and shape, thereby achieving the desired sand making effect.

[0003] Due to different application fields, the requirements for sand are also different. Some fields require the sand to have a better shape (round), but in actual processing, the sand made by the double-roller sand making machine has a poor shape, and a conveyor belt is required to transfer the finished product of the double-roller sand making machine to the sand shaping machine for shaping. This processing method has certain disadvantages. On the one hand, the transmission belt and sand shaping machine will occupy a larger space. On the other hand, the total amount of sand will be lost during the transportation process. Summary of the invention

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: comprising a frame and a box body arranged on the frame, a first motor, a second motor, a first crushing roller and a second crushing roller, a crushing chamber is arranged in the box body, a feeding port for feeding into the crushing chamber is arranged above the box body, and a discharge port for discharging materials from the crushing chamber is arranged below the box body, the first crushing roller and the second crushing roller are arranged along the front-back direction and are located in parallel in the crushing chamber, the gap between the first crushing roller and the second crushing roller serves as a crushing gap for crushing materials, the first motor is provided with a first transmission mechanism for driving the first crushing roller to rotate, and the second motor is provided with a driving The second transmission mechanism for rotating the second crushing roller is characterized in that: the box body is located between the crushing chamber and the discharge port and is connected to a shaping chamber, the inner side wall of the shaping chamber is a spherical grinding wall, a rotating body is rotatably arranged in the middle of the shaping chamber, a throwing chamber with a circular horizontal cross-section is arranged in the rotating body, a receiving port for receiving raw materials falling from the crushing chamber is arranged above the rotating body and connected to the throwing chamber, a plurality of throwing ports are arranged on the outer periphery of the rotating body and connected to the throwing chamber, which throw the raw materials entering the throwing chamber in a tangential direction and hit the grinding wall, and the first motor is provided with a third transmission mechanism for driving the rotating body to rotate.

[0006] By adopting the above technical scheme, the raw materials are crushed into shapes of uniform size in the crushing chamber and fall into the throwing chamber of the rotating body. During the rotation of the rotating body, the raw materials are thrown out from the throwing port in a tangential direction and hit the grinding wall of the shaping chamber for grinding, and finally fall from the discharge port. The space below the crushing chamber is rationally utilized to add a grinding process to optimize the shaping effect. At the same time, the raw materials can be directly ground after being crushed, eliminating the space and cost occupied by the arrangement of additional conveyor belts and sand shaping machines, and reducing the loss of raw materials during transportation.

[0008] By adopting the above technical solution, a grinding block is added in the throwing cavity. On the one hand, the grinding block guides the raw material to fly out of the throwing port in a tangential direction. On the other hand, the raw material just entering the throwing cavity will first collide with the grinding block during rotation, which adds a grinding process and improves the grinding effect.

[0009] The present invention is further configured as follows: the box body is provided with a gathering hopper between the crushing chamber and the shaping chamber, the upper end of the gathering hopper is consistent in shape with the lower end of the crushing chamber, the lower end is consistent in shape with the material receiving port, and the lower end of the gathering hopper is provided with a regulating valve for adjusting the falling flow rate of the raw materials.
