[0002] The existing patent (publication number: CN221334418U) proposes a rock crushing device for geological exploration, including a box body and a crushing roller arranged inside the box body; the front and back of one side of the inner cavity of the box body and above the crushing roller are rotatably connected to a rotating tube through a bearing, one side of the box body is fixedly connected to a fixing frame, one end of the rotating tube passes through the box body and is rotatably connected to one side of the fixing frame through a bearing, and the bottom of the outer surface of the rotating tube is connected to a nozzle. However, this device "because the outer surfaces of the two second gears are engaged with each other, and then when the motor is started, the two crushing rollers will rotate in opposite directions, thereby crushing the rock". The rock is crushed at one time by the two sets of crushing rollers that are engaged with each other. The rock crushing is completed at one time, so the crushing rollers are subjected to greater force during crushing and are more prone to wear, affecting the crushing effect and service life of this device. Summary of the Invention

[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides a rock crushing device for geological exploration, which ensures balanced crushing efficiency between the primary crushing slot and the secondary crushing slot, avoids excessive crushing efficiency of the primary crushing slot causing a large amount of rock to accumulate inside the secondary crushing slot and cause blockage. The crushing process is divided into two steps, which reduces the force applied to each group of crushing mechanisms during the crushing process, and reduces the wear of each group of crushing mechanisms during the crushing process, thereby improving the crushing effect and service life of the device.

[0007] Beneficial effects: 1. When the utility model is used for rock crushing operations in geological exploration, rocks fall from the feed trough into the primary crushing trough, and the rocks are preliminarily crushed by the relative movement between the primary crushing teeth and the primary crushing outer teeth during the rotation of the primary inner crushing block. The preliminarily crushed rocks fall into the secondary crushing trough through the hollow support platform, and the rocks are secondarily crushed by the relative movement between the secondary crushing teeth and the secondary crushing outer teeth during the rotation of the secondary inner crushing block. The qualified rocks fall through the rock screening port to the upper part of the rock conveyor belt and are conveyed to the next processing step. The crushing process is divided into two times, which reduces the force applied to each group of crushing mechanisms during the crushing process, and at the same time reduces the wear applied to each group of crushing mechanisms during the crushing process, thereby improving the crushing effect and service life of the device.

[0008] 2. The crushing drive motor of the utility model directly drives the secondary crushing drive shaft to rotate, and at the same time drives the primary crushing drive shaft to rotate at a speed slower than the secondary crushing drive shaft through the driving gear, the side driven gear and the driven gear ring, so that the primary crushing slot with a larger width and volume is crushed at a slower speed, and the secondary crushing slot with a smaller width and smaller volume is crushed at a higher speed, ensuring the balanced crushing efficiency of the primary crushing slot and the secondary crushing slot, avoiding the excessive crushing efficiency of the primary crushing slot causing a large amount of rock to accumulate inside the secondary crushing slot and cause blockage, and ensuring the normal progress of the overall crushing operation.

[0009] 3. The diameter of the secondary crushing drive shaft of the utility model is smaller than the inner diameter of the primary crushing drive shaft, so that the secondary crushing drive shaft will not generate friction with the primary crushing drive shaft during rotation, thereby avoiding excessive friction and loss between the secondary crushing drive shaft and the primary crushing drive shaft during rotation.
