Single-row self-propelled scallion combine harvester

Abstract

The invention relates to a single-row self-propelled scallion combine harvester, which comprises a chassis provided with a power system, an excavating device and a clamping and conveying device, wherein the excavating device and the clamping and conveying device are arranged on a chassis main frame; the chassis main frame is further provided with a collecting and discharging device positioned at the discharging end of the clamping and conveying device; the excavating device comprises a excavating support frame hinged with the chassis main frame, and a excavating shovel fixedly connected with the excavating support frame; the excavating support frame is connected with the chassis main frame through a lifting hydraulic cylinder. According to the single-row self-propelled shallot combine harvester, the excavating, soil shaking, clamping and conveying, collecting and stacking of the single-row scallion can be completed at one time, so that the harvesting requirements of various scallion can be met; a soil shaking device and an impurity cleaning device finish the twice soil removal treatment of the scallion, and the clean soil rate of the scallion is higher; the clamping and conveying device achieves flexible clamping and nondestructive conveying of the scallion; the collecting and discharging device is used for stacking and laying the scallion, so that manual bundling and collection can be facilitated, and the strength of manual operation can be reduced.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a single-row self-propelled scallion combine harvester. Background technique [0002] Scallions are one of the main characteristic economic crops in my country, and have a long history of planting. The annual area of ​​scallions planted in my country is about 500,000 hm 2 . Green onions have strong adaptability to the living environment and are planted all over the country, especially in Shandong, Henan, Hebei and other regions. my country's annual export volume of green onions accounts for 70% of the world's total, which has played an important role in promoting local economies. [0003] However, since scallions are densely planted crops, and the planting depth is relatively large, this has caused certain difficulties in harvesting scallions. The traditional way of harvesting scallions is manual digging, which is labor-intensive, inefficient and the harvest quality cannot...

Problems solved by technology

[0004] The Chinese patent with the application number 201510345918.4 provides a green onion harvester. This kind of green onion harvester harvests in two rows, the harvesting effect is poor, and it is easy to damage the onion, which cannot meet the requirements of the onion farmers.

[0005] The Chinese patent with application number 201610680215.1 provides a fully automatic crawler-type scallion harvester, which connects the profiling flat shovel and the longitudinal conveying device through a comb-shaped joint and an endless conveyor belt, which can easily cause entanglement and blockage of the scallion roots, and High rate of injury

[0006] The Chinese patent with application number 201610981216.X provides a double-row self-propelled crawler-type scallion combine harvester. This invention uses a double-row collection device to collect two rows of scallions onto a conveyor belt. This invention is extremely prone to scallion clogging , a higher rate of injury

[0007] The Chinese patent with the application number 201610993794.5 provides a single-row self-propelled crawler-type green onion combine harvester. The clamping belt of this invention is narrow, and the green onion is easy to break during the process of clamping and conveying, and the rate of damage to the green onion is high, so it cannot be widely used.
