Abstract

The invention discloses a dry ice blasting cultivation device and a working method, and relates to the technical field of agricultural equipment.The dry ice powder storage device communicates with a telescopic pipe, and an opening and closing head is arranged below the telescopic pipe; the outer wall of the telescopic pipe is connected with one end of a connecting rod, the other end of the connecting rod is connected to a hydraulic mechanism, and the hydraulic mechanism works to drive the telescopic pipe to move up and down. A conical-column-shaped resonance body support is arranged in the telescopic pipe, and an air inlet, a powder inlet and a powder outlet are formed in the conical-column-shaped resonance body support; gas enters a Laval pipe arranged in the cone-column-shaped resonant body support through the gas inlet, enters the cone-column-shaped resonant cavity through an outlet in the outlet end of the Laval pipe and then flows out. Dry ice powder enters from the powder inlet, is converged with gas at the outlet of the conical-cylindrical resonant cavity, and is sprayed out from the powder outlet; the dry ice powder is sprayed out through the powder outlet, and the elastic piece works to open the opening and closing head under the action of impact force. The effect of shallow ploughing and soil loosening can be achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a dry ice blasting farming device and a working method. Background technique [0002] Dry ice blasting is a new method of rock removal. With the advancement of science and technology, more and more engineering projects have adopted dry ice blasting technology. Dry ice is safer than explosives. It is not a civil explosive product and is non-destructive during the blasting process. Vibration and short-wave, the proportion of dust is reduced, and it has little impact on the surrounding environment. [0003] The main problems of farming in my country are high energy and time consumption, high cost, insufficient plowing depth, poor quality of reserve cultivated land resources, more mountainous land, less flat land, less high-fertility land, and more medium- and low-fertility land. Contents of the invention [0004] The purpose of the present invention is to overcome ...
