The invention discloses a continuous tracking type well cellar digging tobacco transplanter and a working method. The continuous tracking type well cellar digging tobacco transplanter comprises a crawler-type walking chassis, the crawler-type walking chassis comprises a generator arranged on the left side of the front end of the support, a tracking type well digging mechanism arranged on the right side of the front end of the support, a seedling tray bracket arranged on the middle cross beam and a control cabinet arranged on the right side of the rear end of the support, and the tracking type well digging mechanism comprises a drill bit; a seedling guide cylinder is arranged on a vertical bracket of the seedling tray bracket; the drill bit and the seedling guide cylinder are distributed on the same straight line in the longitudinal direction; the tracking type well digging mechanism comprises a horizontal moving mechanism and a vertical well digging mechanism, the vertical well digging mechanism is horizontally installed on the horizontal moving mechanism in a sliding mode, and the moving speed of the vertical well digging mechanism is the same as that of the crawler-type walking chassis. The continuous tracking type well cellar digging tobacco transplanter can complete a plurality of movement works within effective time, and the transplanting working efficiency is improved.

The invention belongs to the technical field of winding and unwinding, and particularly relates to a pay-off device for territorial space planning, which comprises a self-adaptive winding drum positioning mechanism, an anti-locking winding drum driving mechanism, a self-pre-tightening guide mechanism and a main body supporting mechanism, the self-adaptive winding drum positioning mechanism is rotationally arranged in the supporting frame, the anti-locking winding drum driving mechanism is located on the side face of the supporting frame, and the self-pre-tightening type guiding mechanism is arranged on the supporting frame in a swinging mode. According to the self-adaptive winding drum positioning mechanism, when the self-adaptive winding drum positioning mechanism faces winding drum bodies with different inner diameters and different widths, jacking and supporting can be synchronously carried out from the inside through a single rotating and locking action, radial fixing and coaxial adjusting of the winding drum bodies are achieved, and the winding drum bodies can be fixed and coaxially adjusted; and the position of the winding drum body can be stopped from the side face, and axial fixing of the winding drum body is achieved.

The present invention belongs to the technical field of radioactive environmental investigation, and specifically relates to a comprehensive collection device for water samples and bottom sediment samples for radioactive environmental investigation, comprising a cylindrical water storage barrel, the upper end of which is open and the lower end is closed, the water storage barrel is filled with crude oil, and a filter and a stirring part are provided inside the water storage barrel, and the stirring part is installed below the filter part. The present invention uses crude oil to absorb suspended impurities originally suspended in the water sample, and drives the water sample in the water storage barrel to circulate up and down through the stirring part to form a first water flow, and the first water flow washes away the bottom sediment sample while bringing the weeds sunk in the water sample back to the surface of the crude oil, so as to achieve the effect of separating the weeds from the bottom sediment sample; the filter part prevents the weeds from falling to the stirring part, and filters the bottom sediment sample; at the same time, the filter part uses the first water flow to move up and down to assist the weeds to float up; the water sample and bottom sediment sample separated and collected by the device can be directly used for detection.

This utility model discloses a speed-coupling device and its installation structure, including a speed-coupling swing arm and a power mechanism. One end of the speed-coupling swing arm is fixed to the power output end of the power mechanism, and the other end of the speed-coupling swing arm is fixed with a bonding plate. The speed-coupling swing arm can be driven by the power mechanism to rotate one end, causing the bonding plate to fit against the end face of the freight car, so that the uncoupling robot trolley moves at the same speed as the freight car under the push of the freight car. The speed-coupling device designed in this utility model can be applied to the uncoupling operation of freight car uncoupling robots, enabling the freight car uncoupling robot to move at the same speed as the railway freight car while the two are relatively stationary, providing a foundation for subsequent uncoupling operations of freight car uncoupling robots.
