Desert tree planting machine

Abstract

The invention discloses a desert tree planting machine. The desert tree planting machine comprises a split type sand absorbing hole forming device, an air and sand separator and an airflow power device. The split type sand absorbing hole forming device comprises a hole forming pipe and a sand absorbing pipe which are in a cylindrical shape. The sand absorbing pipe is sleeved with the hole forming pipe, and an annular cavity is formed between the sand absorbing pipe and the hole forming pipe. The distance between the bottom of the sand absorbing pipe and the bottom of the hole forming pipe can be adjusted. The air and sand separator comprises a rough filtering chamber and a fine filtering chamber, a partition board is arranged between the rough filtering chamber and the fine filtering chamber, and the upper portion of the rough filtering chamber is communicated with the upper portion of the fine filtering chamber. A sand inlet is formed in the top of the rough filtering chamber, and a sand discharging port I is formed in the bottom of the rough filtering chamber. An air outlet is formed in the top of the fine filtering chamber, and a sand discharging port II is formed in the bottom of the fine filtering chamber. Sand discharging valve ports are formed in the sand discharging port I and the sand discharging port II. The sand absorbing pipe is communicated with the sand inlet. The air outlet is communicated with the airflow power device. The operating principle of the desert tree planting machine is different from the operating principle of machine drilling and a ditcher in the prior art, the desert tree planting machine is simple in structure, and a hole can be formed fast.

Description

technical field [0001] The invention relates to a desert tree planting machine. Background technique [0002] The world's first tree planting machine came out in the early 20th century. It was transformed on the basis of an agricultural rice transplanter. It consists of a straight cutter that cuts the soil, a ditch opener that separates the soil to form a tree planting ditch, and a compactor. Consists of a compaction wheel for the soil around the seedlings. The tree planting machine has maintained the structural form of the first agricultural tree planting machine for a long time without improvement. It was not until the 1970s that countries such as Sweden, Finland, former West Germany, and the United States designed and manufactured forestry tree planting machines that were separated from agricultural tree planting machines: one was to install a rotary milling cutter in front of the ditch opener to make ditching The device can cut, break and push the soil to form continuo...
