Front potato harvester for walking tractor

Abstract

The invention provides a front potato harvester for a walking tractor. An installing frame is installed at the front end of the frame of the walking tractor, a discharge plate rotating shaft is connected with the installing frame and a fixed plate cross beam through a discharge rotating shaft bearing, a discharge plate is connected with the discharge plate rotating shaft, the discharge plate and the discharge plate rotating shaft can rotate left and right around the installing frame and the fixed plate cross beam, a digging plough fixing plate is connected with the installing frame, a grating digging plough blade is connected with the digging plough fixing plate, a digging plough baffle is connected with the grating digging plough blade, the digging plough fixing plate is connected with the installing frame and the fixed plate cross beam, a double-acting oil cylinder and the installing frame are connected with an oil cylinder rotating shaft connecting rod, an oil pump is installed on the installing frame, and an oil pump transmission belt is connected with the oil pump and a diesel engine. The front potato harvester for a walking tractor can arrange potatoes in a harvested area intensively, so that potatoes can be picked up conveniently; potatoes growing in shallow soil are not ground, potatoes dug out have high quality, and the digging efficiency is high.

Description

Technical field: [0001] The invention belongs to an agricultural machine, in particular to a front-mounted potato harvester of a walk-behind tractor. Background technique: [0002] At present, the harvesting machines of crops such as potatoes and sweet potatoes mainly include products such as walking tractor-drawn potato harvesters and four-wheel tractor-drawn potato harvesters. The structure of these products is generally that there is a grid-shaped filter soil conveying device behind the plow blades. The grid-shaped filter soil conveying device is mainly composed of a transmission wheel and a grid conveyor chain. Give the transmission wheel, and the transmission wheel drives the grid bar conveyor chain to rotate. When digging potatoes, the plow blades move forward with the tractor, so that the potatoes, potato seedling roots and soil particles on it move backward along the plow surface and enter the grid conveyor chain, and are subject to the vibration caused by the rotat...

AI Technical Summary

Problems solved by technology

The tractor-drawn potato harvester has higher efficiency than manual digging. The main disadvantage is: there is no seedling arrangement mechanism. Before digging potatoes, the potato seedlings need to be manually cut off and moved outside the ground.

The walking tractor towed potato harvester also has the problem that potatoes are thrown from the grid conveyor chain and fall to the operator's feet, which is easy to be stepped on by the operator and affects the normal operation of the operator.
