Description

Technical Field

[0001] The invention belongs to the technical field of agricultural and animal husbandry machinery, and in particular relates to a camless picking device for harvesting crop straw. Background Art

[0002] With the rapid development of my country's agricultural and animal husbandry economy, the demand for agricultural and animal husbandry mechanization technology is also increasing. To reduce the environmental pollution caused by straw burning and improve straw harvesting efficiency, a camless picking device has been developed. Compared with similar pickers on the market, this invention has the advantages of simple structure, high picking efficiency, simple maintenance, and convenient replacement of spring tines. Summary of the Invention

[0003] The object of the present invention is to provide a cam-free picking device for picking up crop straws in the field.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] The camless picking device includes a frame, a grass press assembly, a spring tooth guard plate, a spherical bearing, a driving sprocket, a hinge guard plate, and a spring tooth beam. The grass press assembly is rotatably connected to the upper parts of both ends of the frame. The spring tooth guard plate and the hinge guard plate are fixedly installed on the frame at intervals, and the hinge guard plate is installed above the spring teeth. The spherical bearings are fixedly installed at both ends of the frame and rotatably connect the spring tooth beam and the frame. The driving sprocket is fixedly installed at the end of the spring tooth beam. The spring tooth beam is rotatably connected to the frame through spherical bearings at both ends. The grass press assembly includes a large support plate, a small support plate, a grass press, and a grass pressing roller. The grass presser is rotatably connected to the large support plates at both ends, the small support plates are connected to the large support plates at both ends by bolts, and the grass pressing roller is rotatably connected to the small support plates at both ends. The elastic tooth beam includes an elastic tooth beam frame, an elastic tooth pad, and elastic teeth. The elastic teeth are connected to the elastic tooth pad and the elastic tooth beam frame in turn by bolts. The hinge guard plate includes an elastic tooth lower guard plate, an elastic tooth upper guard plate, a hinge baffle, and a hinge. The hinge is welded and fixedly connected to the elastic tooth lower guard plate and the elastic tooth upper guard plate, and the hinge baffle is welded and fixedly connected to the elastic tooth upper guard plate, and is located on the inner side of the connection between the elastic tooth lower guard plate and the elastic tooth upper guard plate.

[0006] The beneficial effects of the present invention are:

[0007] Compared with ordinary pickups, the present invention eliminates the cam track structure, simplifies the structure, reduces failure points, and adopts a non-fastening fixing form for the spring teeth. A certain gap is left between the spring teeth and the spring tooth beam and the spring tooth pad, so the service life of the spring teeth is longer. In addition, a hinge guard is provided to facilitate the replacement and maintenance of the spring teeth. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0013] The present invention will be further described below in conjunction with the accompanying drawings:

[0014] like Figure 1-4 As shown, the camless picking device includes a frame 1, a grass press assembly 2, a spring tooth guard plate 3, a spherical bearing 4, a drive sprocket 5, a hinge guard plate 6, and a spring tooth beam 7. The grass press assembly 2 is rotatably connected to the upper part of the frame 1 at both ends, the spring tooth guard plate 3 and the hinge guard plate 6 are fixedly installed on the frame 1 at intervals, and the hinge guard plate 6 is installed above the spring tooth 14. The spherical bearing 4 is fixedly installed at both ends of the frame 1 and rotatably connects the spring tooth beam 7 and the frame 1. The drive sprocket 5 is fixedly installed at the end of the spring tooth beam 7, and the spring tooth beam 7 is rotatably connected to the frame 1 through the spherical bearings 4 at both ends.

[0015] The grass press assembly 2 includes a large support plate 8, a small support plate 9, a grass press 10, and a grass press roller 11. The grass press 10 is rotatably connected to the large support plates 8 at both ends, the small support plate 9 is connected to the large support plates 8 at both ends by bolts, and the grass press roller 11 is rotatably connected to the small support plates 9 at both ends.
