Small hand-pushed tree planting machine for agriculture and forestry

Abstract

The invention relates to a small hand-pushed tree planting machine for agriculture and forestry. The small hand-pushed tree planting machine comprises a traveling frame with a hole digger suspended therein. The hole digger comprises an engine which is connected with a gear box through a connecting plate, and an output shaft of the gear box is connected with a drill bit. A base connected with the connecting plate is arranged at the bottom of the gear box and connected with a handle, a reset trigger is arranged on the handle and controls four sub brake cables through a main brake cable connected to a converter, and the four sub brake cables are respectively connected to four positioning devices which are arranged on sleeves of four vertical posts of the traveling frame and used for fixing the hole digger and keeping the hole digger in an initial suspending state. A plurality of bending pipes containing extension springs are arranged around the four vertical posts, tail end of each of the extension springs is connected with a lift rope correspondingly, and the lift ropes are gathered by a connector and then are connected to a lift support on the base through a fixed pulley mounted in the middle of a cross beam of the traveling frame. The handle-pushed tree planting machine is small in size, convenient to move, safe and laborsaving in operation and capable of meeting requirements for hole digging operations better.

Description

technical field [0001] The invention relates to a small hand-push agricultural and forestry tree planting machine for tree planting. Background technique [0002] In view of the increasing emphasis on ecological protection in China, the workload of afforestation in various places is very huge. The general agronomic requirements for digging pits in tree planting operations are 400-500mm in diameter and 500-600mm in depth. [0003] The current operation methods are generally divided into three types: first, use the excavator and implements hung behind the tractor. This method is characterized by high operation efficiency. The disadvantage is that some plots cannot be accessed, mountainous areas cannot be operated, and some areas are divided into blocks. , the amount of work in the block is not large, and operators are not inclined to purchase such equipment; the second way is to use a portable gasoline engine-powered digging machine, which is characterized by good portability...

Problems solved by technology

[0003] The current operation methods are generally divided into three types: first, use the excavator and implements hung behind the tractor. This method is characterized by high operation efficiency. The disadvantage is that some plots cannot be accessed, mountainous areas cannot be operated, and some areas are divided into blocks. , the amount of work in the block is not large, and operators are not inclined to purchase such equipment; the second way is to use a portable gasoline engine-powered digging machine, which is characterized by good portability, and the disadvantage is limited to the operator's operating safety and labor intensity. The main engine generally uses a gasoline engine with a maximum horsepower of 3.5 horsepower, and the maximum diameter of the drill bit is 300mm. There is a big difference in the agronomic requirements for tree planting and digging pits, and manual secondary operations are required; the third method is manual operation, and the disadvantage is that it requires a lot of labor.
