The invention discloses a distance measuring device with positioning and dotting functions for farmland measurement planning, and particularly relates to the technical field of farmland planning, thedistance measuring device comprises a support frame, a fixed block and a shell are embedded and fixed on the support frame, the shell is respectively arranged at the front and rear sides of the fixedblock, and the upper side surface of the shell is fixedly connected with a handle; a ball screw is fixedly embedded in the fixing block, a sleeve is fixedly welded to the lower side face of the ball screw, a positioning insertion rod is inserted into the sleeve, a rotating wheel is rotatably connected into the shell, a measuring tape is wound around the annular side face of the rotating wheel, oneend of the measuring tape sequentially penetrates through the shell and the supporting frame, and the lower side of the supporting frame is in engaged connection with an adjusting screw through threads; the lower side of the adjusting screw is rotationally connected with a connecting rod through a bearing, and the left portion and the right portion of the connecting rod are connected with movingwheels through rotating shafts. According to the invention, positioning and dotting are carried out while distance measurement is realized, the operation is simple, the workload of personnel is reduced, and the height of the support frame is also convenient to adjust.
Description
technical field [0001] The invention relates to the technical field of farmland planning, more specifically, the utility model relates to a distance measuring device for farmland measurement and planning with the function of positioning and dotting. Background technique [0002] Cultivated land planning is also called "cultivated land internal planning". Under the premise of a given area of cultivated land, it is a comprehensive arrangement for the measures to rationally organize the use of cultivated land. Contents include: (1) crop layout; (2) temporal and spatial organization of cultivated land; (3) planning of cultivated fields (direction, side length, shape, etc.); (4) planning of field channels; (5) planning of field roads; 6) Forest protection belt planning. [0003] In the prior art, the distance measuring device used in the existing farmland measurement planning can generally only measure the length of the farmland, and use the positioning rod alone for dot posi...
