Abstract

A horizontal sampling soil drilling rig and a control method are used to solve the problem that the soil sampling device in the prior art has difficulty in horizontal sampling. The horizontal sampling soil drilling rig includes a rack, a connection assembly, a drive mechanism, a spiral drill rod, and a sampler. The rack is provided with a spline shaft and a screw rod in parallel. The screw rod and the spline shaft are connected through a first transmission assembly in transmission connection. The drive mechanism includes a rotation driver, a second transmission assembly, and a spline shaft sleeve. The spline shaft sleeve is rotationally connected to the rack, and the spline shaft sleeve and the spline shaft mesh with each other. The rotation driver is connected with the spline shaft through the second transmission assembly in transmission connection.
