This invention discloses an unmanned tracked robot for agricultural sowing, relating to the field of agricultural machinery technology. It includes an unmanned tracked sowing vehicle with a trapezoidal block fixedly connected to its top. A fixed horizontal plate is fixedly connected to the side wall of the trapezoidal block, and a centrifugal sowing component is mounted on the top of the fixed horizontal plate. The centrifugal sowing component includes a stepper motor fixedly connected to the side wall of the trapezoidal block. The centrifugal sowing component utilizes centrifugal force to throw seeds from the sowing device, causing the seeds to disperse evenly within a certain range. This avoids excessive concentration or uneven distribution of seeds, ensuring uniform seed distribution in the field and promoting uniform crop growth. The centrifugal sowing device can perform sowing operations at a high speed, significantly improving sowing speed compared to traditional manual sowing or some low-speed sowing methods. It can complete large-area sowing tasks in a short time, making it particularly suitable for large-scale agricultural production and effectively shortening the sowing cycle.

The invention discloses a non-pilot-tunnel starting device and a non-pilot-tunnel starting method for a vertical shaft heading machine. The non-pilot-tunnel starting device and the non-pilot-tunnel starting method for the vertical shaft heading machine solve the problems that in the prior art, vertical shaft starting depends on pilot tunnel starting and cannot adapt to vertical shaft heading machines of various diameters. The pilot tunnel-free starting device of the vertical shaft heading machine comprises a plurality of supporting ring units which are coaxially arranged, and every two vertically adjacent supporting ring units are detachably connected; each supporting ring unit is of an annular supporting structure composed of a plurality of plate-column assemblies and a plurality of reducing assemblies, and the reducing assemblies are detachably connected with the adjacent plate-column assemblies and / or every two adjacent plate-column assemblies. According to the pilot-tunnel-free starting device for the vertical shaft heading machine, the multiple layers of supporting ring units are matched with one another, so that the pilot-tunnel-free starting device is adaptive to rapid assembly and starting of vertical shaft heading machines with different heights. Vertical shaft heading machines of various types and different diameters can be assembled and debugged through the variable-diameter assembly, and the adaptability of the assembling device is improved.
