Description

A kind of supporting spring type hemp crop harvester

technical field

The invention relates to the technical field of agricultural machinery, in particular to a supporting spring type hemp crop harvester.

Background technique

The large-scale production near agriculture is to adopt advanced agricultural production technology and use efficient agricultural machinery to cultivate on concentrated land. It can not only improve the labor productivity of agriculture, reduce the production cost per unit land area, increase the output, and make the price of agricultural products have a market competitive advantage under the premise of a certain production input, but also drive the transportation, agricultural machinery manufacturing, and maintenance services. The development of a series of related industries such as warehousing, storage and drying has formed a large-scale agricultural development situation.

Up to now, harvesters for tall and thick stalk crops mostly use a motor vehicle with a cab and a power device installed on the chassis as the harvester body, and a reciprocating cutter horizontally arranged in front of the motor vehicle is used to cut the stalks. Arranged in the middle of the car body of the motor vehicle, the stalks are clamped and lifted along the driving direction of the motor vehicle and transported to the rear of the harvester for stacking. The self-propelled harvester will increase the harvesting cost of tall and thick stalk crops. The matching harvester can make full use of the tractor, and the matching header can be connected to the tractor through the suspension frame to carry out field harvesting operations, which can greatly reduce the harvesting work. cost.

Up to now, there are mainly two cutting methods of the cutting device of the high and thick stalk crop harvester: reciprocating cutting and rotary cutting. The reciprocating cutter adopts a single-point connection. There are two supporting seats at the lower part of the cutter, which are used to support part of the quality of the cutter. Cutting is carried out through the reciprocating motion of the moving blade. kind. The driving mechanism of the double-moving knife reciprocating cutter can make the upper and lower moving knives do reverse reciprocating motions with equal strokes. The common types of cutters for rotary cutters are linear, curved, smooth disc, sawtooth disc, planetary rotary and star tooth. The rotary cutter has high cutting speed and strong cutting capacity. Although the single-moving knife reciprocating cutter has a simple structure, the single-cutting speed is low, the reciprocating motion inertial force is large, the vibration is large, and it is difficult to balance the inertial force.
