Description

Technical Field

[0001] This invention relates to the field of garlic scape harvesting equipment, and in particular to a non-blade-piercing garlic scape splitting harvester. Background Technology

[0002] In the application of the applicant's existing "Garlic Scape Harvester (Application No.: 2024227885135)" and similar equipment, the blade is often used to directly cut the garlic scape below the clamping mechanism. This cutting method has the following drawbacks: a high risk of accidental cuts to garlic shoots or leaves; the blade is sensitive and requires frequent maintenance; the blade is prone to dulling and jamming under muddy conditions; and the cutting window is narrow and stability is generally poor when the garlic scape's posture is variable.

[0003] To reduce damage to plants and safety hazards, this application proposes a bladeless disconnection method of "first weakening with needles, then disconnecting by traction". Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a bladeless garlic scape severing and harvesting machine. Its core component is a rotating assembly powered by clamping rollers located below the clamping and lifting channel. This assembly drives circumferentially distributed needles to form a circumferential piercing band at the junction of the garlic scape and the garlic bulb. As the clamping rollers continue to lift and pull, the garlic scape naturally breaks off at the weakened band, avoiding the risk to plants and personnel from direct blade cutting.

[0005] A knifeless garlic scape severing and harvesting machine includes a harvesting vehicle and a clamping and harvesting mechanism located at the front end, characterized in that: A garlic scape breaking mechanism is provided on the rear side of the clamping and harvesting mechanism. The garlic scape breaking mechanism includes a rotatable shaft and a bevel gear fixedly connected to it. The bevel gear meshes with a drive bevel gear from the harvesting vehicle. Multiple needles are arranged circumferentially on the bevel gear or the turntable above it to form circumferential piercing holes at the junction of the garlic scape and the garlic bulb for easy breaking.

[0006] Furthermore, in order to better realize the present invention, the active bevel gear is coaxially disposed at the end of the roller below the clamping and harvesting mechanism, so that the garlic scape breaking mechanism and the clamping roller take force synchronously.

[0007] Furthermore, in order to better realize the present invention, the garlic scape breaking mechanism is arranged below the inclined guide plate and the square limiting plate, and the tip of the needle is located in the ring area through which the garlic scape passes.

[0008] Furthermore, in order to better realize the present invention, the needle is replaceable, the needle length and circumferential density are adjustable, and the needle seat is fixed by a thread or a chuck.

[0009] Furthermore, in order to better realize the present invention, the height of the rotating shaft is adjustable relative to the ground to match garlic scapes of different diameters; a protective cover and chip guide holes are provided on the outer periphery of the garlic scape breaking mechanism.

[0010] Furthermore, in order to better realize the present invention, the needles are evenly distributed in a single or multiple loops around the circumference, or are distributed in a staggered spiral pattern to form a continuous circumferential weakening zone.

[0011] A method for cutting garlic scapes using a non-blade-piercing garlic scape cutting harvester according to any one of claims 1 to 8, characterized in that: while the clamping roller lifts the garlic scape, the garlic scape passes through the piercing area of ​​the garlic scape cutting mechanism, and the needle forms a circumferential piercing hole at the junction of the garlic scape and the garlic bulb, and then the garlic scape is naturally cut off at the piercing hole under the traction of the clamping roller.

[0012] The beneficial effects of the present invention are: The elimination of sharp blades significantly reduces the risk of injury to garlic sprouts, workers, and surrounding plants. The needle-piercing design creates a circumferential weakening zone, with concentrated and consistent break points, adapting to various working conditions. The needle body can be quickly replaced and has strong resistance to mud and sand; it is synchronized with the clamping rollers, ensuring that the break-off rhythm matches the clamping and lifting action.

[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] Figure 1-Figure 4 In one specific embodiment of the present invention, a rotating shaft 601 is vertically arranged below the inclined guide plate 501 and the square limiting plate 502 above the clamping roller, within the channel through which the garlic scape passes. A bevel gear 602 is fixedly connected to its bottom. The bevel gear 602 meshes with a driving bevel gear 305 that takes force from the front end. The driving bevel gear 305 is coaxially mounted on the end of a roller 201 below. A plurality of needles 603 are evenly distributed on the outer edge of the bevel gear 602 or the turntable above it, with the needle tips pointing towards the annular area through which the garlic scape passes.

[0018] The 603 needle is preferably replaceable and can be installed using a threaded or slotted chuck. The needle length, number of needles, and circumferential density are adjustable to accommodate garlic scapes of different diameters and maturity levels. The needle tip can be made into a small cone to reduce penetration resistance. The needle array can be a single-ring circumferentially evenly distributed, a double-ring staggered distribution, or a spiral distribution to form a continuous weakening zone. The overall height of the disconnecting mechanism relative to the ground is adjustable to align with the transition area between the garlic scape and the garlic bulb.

[0019] To prevent jamming, a protective cover is installed on the outside of the disconnecting mechanism and a chip guide hole is provided to facilitate the discharge of mud and debris. Preferably, the ratio of the circumferential linear velocity of the disconnecting mechanism to the outer circumferential linear velocity of the clamping roller is controlled within the range of 0.8 to 1.2 to obtain a stable perforation density.

[0020] In this embodiment, the method of use is as follows: when the clamping roller lifts the garlic scape, it guides the garlic scape through the needle-piercing area of ​​the disconnecting mechanism; the rotating needle forms a circumferential piercing band at the junction of the garlic scape and the garlic bulb, and the garlic scape is naturally disconnected at this point and falls towards the conveyor belt as the clamping roller pulls it; no blade cutting is required.

[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.
