It is difficult to apply vertical pressure at the handle, which has the problems of difficulty in soil entry, low soil extraction efficiency, and large workload; although some soil extractors are equipped with foot pedals, they can only be used for ring cutters and hollow connecting rods. It is also difficult to significantly improve the working efficiency of the earth extractor when working at one position of the joint, and the added foot pedal makes the structure of the earth extractor more complicated, which is inconvenient for installation, transportation and storage; in view of this, it is urgent to design a Portable high-efficiency borrower for deep borrowing in the field.

SUMMARY OF THE INVENTION

In view of the problems and defects existing in the above-mentioned prior art, the purpose of the present utility model is to provide a novel borrower, so as to improve the soil borrowing efficiency of the deep soil in the field and facilitate timely understanding of the physical and chemical properties of the soil at different depths.

The technical solution adopted by the utility model to solve the technical problem is a new earth extractor, which includes a bulldozer slider, a ring cutter, a hollow connecting rod, a foot pedal, a limit block I, a limit block II, and a limit block III , limit pin, limit hole, connecting rod hole I, connecting rod hole II, connecting rod hole III, push rod, bulldozing handle, soil pressing handle;

It is characterized in that the bulldozer slider is connected with the push rod through threads, and the push rod is welded to the bulldozer handle through the limit block I, the limit block II, the limit block III and the inner hole of the foot pedal, so the push rod is welded to the bulldozer handle. The limit block I, limit block II and limit block III are all welded on different parts of the hollow connecting rod, the foot pedal is installed on the limit pin through the limit hole, and the limit pin is installed on the connecting rod hole I; the ring cutter is connected with a hollow connecting rod through a thread, and the hollow connecting rod is welded on the soil pressing handle.

The working principle of a new portable earth borrower of the utility model is as follows:

When taking soil, first install the foot pedal on the hollow connecting rod through the limit pin and the connecting rod hole I, and then rotate the foot pedal to the horizontal position around the limit pin, so that the upper end surface of the foot pedal is in line with the limit The lower end of the block I is in contact, and the other end extends the hollow connecting rod in the horizontal direction. Then hold the soil pressing handle with both hands and place it on the ground in the vertical direction. At the same time, press the soil extractor into the soil through the foot pedal. After borrowing soil several times, pull out the limit pin, take out the pedal, and install it to the higher position of the hollow connecting rod through the limit pin, connecting rod hole II and limit block II. Rotate around the limit pin to a horizontal position, and use the same method to take soil from a deeper position below the surface. After several repeated operations, the soil within the length of the hollow link can be easily taken out.

The beneficial effect of the utility model is that the position of the foot pedal can be adjusted through the limit pin, the connecting rod hole I and the limit block I, so as to take out the soil of different depths, and the soil extraction efficiency of the deeper soil in the field can be significantly improved. After completion, directly rotate the foot pedal to the vertical direction to put the whole earth extractor into the cylinder for storage and transportation. It is portable and efficient, and is especially suitable for efficient deep soil extraction in farmland scientific experiments.
