Description

Light seedling planting pit excavator

technical field

The utility model relates to the technical field of garden machinery, in particular to a seedling planting and digging device.

Background technique

To increase forest coverage, protect the ecological environment, and fix wind and sand must start with afforestation. Since the reform and opening up, more than 47.57 billion trees have been voluntarily planted nationwide, and the forest coverage rate has increased from 12% in the early 1980s to 18.21% at present; the green coverage rate of urban urban construction areas has increased from 10.1% in 1981 to today's 31.66%. Green has improved our ecological environment and planted a green shade in people's hearts. The use of mechanization can accelerate afforestation. Among them, the afforestation digging machine is the main machine in afforestation equipment, and its performance directly affects the speed and quality of afforestation. At present, the digging head of the digging machine at home and abroad basically adopts the screw type, the lifting mechanism is a three-point suspended plane four-bar mechanism, and the power is a tractor-mounted type. Although the overall structure is simple, it has the following defects: (1) The tractor drive is not applicable (2) The power mechanism increases the cost of the whole machine for the tractor. (3) The overall weight is large, and it is easy to compact the soil, which is not conducive to soil and water conservation and seedling growth.

Utility model content

The technical problem to be solved by the utility model is to provide a light seedling planting pit excavator with a simple structure, flexibility and lightness in view of the above technical deficiencies.

The technical solution adopted by the utility model is: provide a light seedling planting pit excavator, including a vehicle frame, a power mechanism, an executive mechanism, and a running mechanism; the power mechanism is an internal combustion engine installed on the vehicle frame; the running mechanism is installed on the lower part of the vehicle frame ;The power input end of the traveling mechanism is connected with the power output end of the power mechanism; the executive mechanism is a hydraulic pump driven by an internal combustion engine, a hydraulic motor driven by a hydraulic pump, a hydraulic rod, and an auger driven by a hydraulic motor; the upper part of the hydraulic rod It is hinged with the column fixed on the right end of the frame; the lower end of the hydraulic rod is hinged with a base; the left end of the base is provided with a dovetail block; the column is provided with a dovetail groove slidingly connected with the dovetail block; the hydraulic motor is installed on the base; the frame Handrails are installed on both sides of the right end of the vehicle; the travel control rod of the traveling mechanism is installed on the handrail; the reversing control rod of the hydraulic motor and the lifting control rod of the hydraulic rod are respectively installed on both sides of the right end of the frame.

To further optimize the technical proposal, the walking mechanism of the light seedling planting pit excavator is a crawler belt.

Further optimize this technical scheme, the right end of the vehicle frame of light seedling planting pit excavator is equipped with fender.

The beneficial effect of the utility model is that: the internal combustion engine is selected to provide power, and the utility model is not limited by the place of use. The structure of the frame is simple, and it adopts a hand-held structure. Manual operation can change the direction of travel. It is not equipped with a manual operation table or an operation room, and is light and flexible. The walking mechanism adopts crawler belts, which can adapt to a wide range of terrain and will not compact the soil. The control of the actuator is simple, and the hydraulic motor and the hydraulic rod are controlled separately, which is beneficial to improve the efficiency of digging.
