AI Technical Summary
The rubber actuating strips of existing garlic harvesters are not rigid enough and are prone to deformation, which can lead to feeding jams, missed harvests, and machine shutdowns, affecting operational efficiency and reliability.
The actuating bar is made of metal, with both ends bent into arc-shaped guide sections. The surface is treated with carburizing, nitriding, or spraying, and has chamfers or rounded corners. It is connected to the clamping device through elastic connectors to achieve height and angle adjustment to adapt to different terrain conditions.
The rigidity and wear resistance of the actuating bar have been improved, reducing the risk of jamming and missed feeding, enhancing the continuity of feeding, reducing abrasions on garlic sprouts and impact damage to equipment, and improving the stability and efficiency of operation.

Abstract
Description
Technical Field
[0001] This invention relates to the field of garlic harvesting equipment technology, and in particular to an improved structure of the actuating bar of a garlic harvester clamping device. Background Technology
[0002] Garlic harvesters typically have a guide bar before clamping and lifting to straighten leaning garlic shoots and guide them into the clamping path. Existing solutions mostly use rectangular rubber guide bars, which are affected by soil clods, gravel, and straw in the field. The rubber bars lack rigidity and are prone to deformation, causing feeding jams and resulting in missed harvests and machine shutdowns for cleaning, thus affecting operational efficiency and reliability.
[0003] Therefore, a prying structure with higher rigidity and wear resistance is needed, and the risk of getting stuck in the soil should be reduced through geometric guidance. Summary of the Invention
[0004] To overcome the shortcomings of the prior art, the present invention provides an improved structure for the actuating bar of a garlic harvester clamping device.
[0005] An improved structure of the actuating bar in a garlic harvester clamping device is provided. This device is used to clamp garlic shoots and lift the garlic for harvesting. An actuating bar is provided on the feed side of the clamping device. Its key feature is: The actuating bar is made of metal, and its two ends are bent into curved guide sections, which are used to straighten the tilted garlic sprouts during the movement of the device and guide them into the clamping path of the clamping device.
[0006] Furthermore, in order to better realize the present invention, the metal material of the toggle bar is one or more of spring steel, stainless steel or wear-resistant alloy steel, and the surface of the toggle bar is subjected to at least one surface strengthening treatment of carburizing, nitriding, spraying or electroplating.
[0007] Furthermore, in order to better realize the present invention, the actuating bar is a plate-shaped structure with a plate thickness of 1.2 to 3.0 mm.
[0008] Furthermore, in order to better realize the present invention, the bends at both ends of the toggle bar are rounded, with a bending radius of 3 to 30 mm and a bending angle of 20° to 120°.
[0009] Furthermore, in order to better realize the present invention, the toggle bar is detachably installed at the front end of the clamping device, and its height or angle can be adjusted through an elongated hole or multiple positioning holes.
[0010] Furthermore, in order to better realize the present invention, an elastic connector is provided between the toggle bar and the clamping device so as to generate a yielding rebound when encountering a hard foreign object and reset after the external force is released.
[0011] Furthermore, in order to better realize the present invention, the edge of the agitator that contacts the garlic sprout is provided with a chamfer or rounded corner to reduce abrasion to the garlic sprout.
[0012] The beneficial effects of this invention are: Metal replaces rubber, improving rigidity and wear resistance, and enhancing feeding continuity; the guide section with both ends bent into arcs creates a smooth and converging guide at the feed inlet, reducing jamming and missed feeding; the adjustable and repositionable configuration adapts to different ground conditions and reduces impact damage; the simple structure, ease of manufacturing and maintenance, and suitability for large-scale promotion.

[0014] In the picture, 1. Holding device; 2. Actuating bar. Detailed Implementation
[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0016] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.
[0017] Figures 1-2 In one specific embodiment of the present invention, an improved structure of the actuating strip of a garlic harvester clamping device is provided, wherein an actuating strip 2 is provided on the feeding side of the clamping device 1. The actuating strip 2 is a metal plate-shaped component with both ends bent into arc-shaped guide sections, and the length of the strip is arranged along the traveling direction of the device. During operation, the arc-shaped guide sections first contact the tilted garlic sprouts and lift them, and then guide the garlic sprouts into the clamping path of the clamping device 1; because the actuating strip 2 has sufficient rigidity and wear resistance, the feeding area maintains a stable shape, reducing the interference of soil clods and other debris on the feeding.
[0018] The actuating strip 2 is made of spring steel or stainless steel with a thickness of 1.2–3.0 mm; the bending radius at both ends is 5–15 mm, and the bending angle is 30°–90°; the surface is treated with nitriding or spraying a wear-resistant layer to improve wear resistance and corrosion resistance. The edges that come into contact with the garlic sprouts are chamfered or rounded to reduce abrasion to the plant's surface.
[0019] The toggle bar 2 is detachably installed at the front end of the clamping device 1 by screws. The mounting hole is an oblong hole to achieve fine adjustment of pitch angle and height. An elastic washer or torsion spring component is set between the toggle bar 2 and the mounting part. When encountering hard foreign objects, it is allowed to give way instantly and reset after the external force is removed, reducing impact and structural damage.
[0020] The toggle bar 2 can be manufactured using a process route of sheet metal blanking—stamping—bending—deburring—surface treatment—assembly; after assembly, the angle and height are calibrated to obtain a stable guiding effect.
[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention, as long as they do not depart from the spirit and scope of the technical solutions of the present invention, should be covered within the scope of the claims of the present invention.
