A vegetable harvester

Abstract

The invention discloses a leafy-vegetable harvester. The leafy-vegetable harvester includes a main rack, a wheel-type frame and a gearbox which is mounted on the main rack; the fixed frame is fixed at the front end of a roller tractor, and the main rack and the fixed frame are connected to be a whole, wherein the main rack can do lifting motion relative to the fixed frame; an input shaft of the gearbox is connected with a power output end of the tractor; regarding the gearbox output shaft towards the ground, the terminal of the gearbox output shaft is connected with a leafy-vegetable cutting mechanism, the middle segment of the gearbox output shaft is connected with a sweeping mechanism, and the upper segment of the gearbox output shaft is connected with a vegetable discharging mechanism; the leafy-vegetable cutting mechanism, the sweeping mechanism and the vegetable discharging mechanism cooperate to completely cut leafy vegetables. According to the leafy-vegetable harvester, firstly, the tractor is adopted to drive the harvester, the power is sufficient, the endurance time is long, and it is convenient to pass through fields; then, the harvester is arranged at the front, the occupation space of a whole machine is less, and it is convenient to adjust the cutting range; besides, a four-bar-linkage mechanism is designed between the tractor and the harvester, the lifting of the main rack can be achieved through an oil cylinder, the field passing capability of the harvester is ensured, and the harvester is particularly suitable for the harvest of field vegetables.

Description

technical field [0001] 本发明属于收割机技术领域,具体涉及一种叶菜收割机。 Background technique [0002] 随着现代化农业技术的发展,蔬菜机械化收获技术在我国越来越受到重视。 在我国,虽然目前已研究了多种叶菜类收割机,但在实际应用中叶菜的收获基本上仍然采用人工收获,不仅劳动强度而且收获效率低下,叶菜类机械化收获技术仍然没有得到普遍的 application. 究其原因,还是因为现有技术中的收割机,大都存在一些使用上的不便,或者收割效果不好的问题。 因此,本领域技术员有必要提供一种功能齐全、结构紧凑、能保证切割效果的叶菜收割机。 Contents of the invention [0003] 针对上述现有技术中的不足,本发明提供了一种可在土壤上或者土壤下对叶菜根部切割,保证叶菜完整、铺放整齐、切割顺利的叶菜收割机。 [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] 一种叶菜收割机,包括主机架、固定架、安装于主机架上的变速箱;所述固定架固定在轮式拖拉机前端,所述主机架与固定架相对可升降的连为一体,所述变速箱的输入轴与拖拉机的动力输出端连接,对于朝向地面的变速箱输出轴在其末端连接叶菜切割机构、中段连接清扫机构、上段连接出菜机构;所述叶菜切割机构、清扫机构、出菜机构构成对叶菜进行完整切割的配合。 [0006] 优选的,所述固定架两侧下端分别通过销轴连接一连板的一端,两侧连板的另一端均通过销轴连接在主机架下端;固定架两侧上端分别通过销轴连接一升降连板的一端,升降连板另一端通过销轴连接在主机架上端;所述主机架、固定架、连板、升降连板形成四连杆机构;所述固定架两侧通过销轴分别固连有油缸,两侧油缸的输出轴与两侧的升降连板对应连接,配合主机架相对固定架进行升降。 [0007] 优选的,所述主机架外侧下端还设有保证叶菜切割机构与地面距离的限深轮调节机构。 [0008] 进一步的,所述限深轮调节机构包括限深轮、限深轮轴、限深轮架、限深轮架转轴,所述限深轮架通过限深轮架转轴可转动的固定在主机架两外侧下端,所述限深轮通过限...

AI Technical Summary

Problems solved by technology

In our country, although a variety of leafy vegetable harvesters have been studied, in practical applications, the harvesting of leafy vegetables is basically still done manually, which is not only labor-intensive but also low in harvesting efficiency, and the mechanized harvesting technology of leafy vegetables has not yet been widely adopted. application

Tracing it to its cause, or because most of the harvesters in the prior art have some inconveniences in use, or the problem that the harvesting effect is not good
