Abstract: Provided are a ray collimation device and a radiation inspection device. The ray collimation device includes a collimation assembly, a transmission assembly, and a driving assembly. The collimation assembly includes a first collimation block and a second collimation block. A collimation opening for collimating rays is provided between the first collimation block and the second collimation block. The transmission assembly includes a first transmission component and a second transmission component connected in a transmission manner, the second transmission component is connected to the driving assembly, and the first transmission component is connected to the first collimation block and the second collimation block. Under a drive of the driving assembly, the first transmission component is movable to drive the first collimation block and the second collimation block to move toward or away from each other at a same speed, thereby adjusting a width of the collimation opening.
