The invention discloses an agricultural crane capable of achieving video monitoring. The agricultural crane comprises a crane body, a hydraulic cylinder, a supporting table, a rotary table, a plane bearing, a servo motor I, a supporting beam, a labor-saving pulley block, a pull cable, a servo motor II, a worm, a worm gear, a winding disc, a shaft, an electronic crane scale, a lifting hook, a voicebroadcaster and a controller. Through the device, the situation that a frame loaded with crops directly makes contact with mud, and the weighing accuracy is influenced is avoided. During usage, a cover is rotated firstly, a hydraulic hinge is rotated to the target angle, then a hydraulic cylinder I is started, a movable plate slides out of a rectangular groove to the target position, the action of the hydraulic cylinder I is stopped, and finally the frame loaded with the crops is placed on the movable plate. The integral height can be flexibly adjusted, and the agricultural crane can conveniently pass through some tunnels and other traffic sites with the height limiting requirement. In the large-batch crop buying and selling process, the video monitoring function can be achieved, a camera is fixedly connected to the top end of the supporting beam and can monitor the whole buying and selling process, and unnecessary dispute is avoided.
