Eagle beak structure on garlic harvesting and clamping device

Abstract

The invention discloses an eagle beak structure on a garlic harvesting clamping device, and relates to the technical field of agricultural harvesting machinery. In order to solve the problem that lodging garlic sprouts attached to the ground cannot be effectively lifted by an existing device to cause missing harvesting, an adjustable eagle beak structure is arranged at the front end of a single clamping mechanism, and a telescopic mechanism driven by a screw rod is connected with a wedge-shaped seedling lifter, so that lodging crops are accurately straightened. The structure comprises a gantry mounting frame, a telescopic rod with thread transmission and a ground contact wedge block, has the characteristics of adjustable height, synchronous movement along distance, strong ground breaking capability and the like, and effectively overcomes the technical defects of poor seedling supporting effect and low adaptability of a traditional device. According to actual measurement, the lifting rate of the lodging garlic sprouts is greatly increased, and the method is particularly suitable for mechanical harvesting operation under rainy lodging disasters.

Description

Technical Field

[0001] The invention relates to the technical field of garlic harvesting equipment, in particular to a hawk beak structure on a garlic harvesting clamping device. Background Art

[0002] In 2024, the applicant submitted an invention patent with patent number 202411444362X, "A garlic harvesting clamping device with manually adjusted row spacing". The equidistant spacing adjustment of the clamping mechanism is achieved by adjusting the rotating shaft, and a synchronous belt mechanism is used to clamp the garlic sprouts, and a rubber toggle bar is used to straighten slightly fallen plants. However, in actual applications, it was found that for garlic scapes that are completely attached to the ground or have a large falling angle, the toggle bar of the existing device is difficult to effectively straighten and introduce it into the clamping mechanism due to its fixed height and limited contact area. As a result, some fallen garlic scapes are not clamped and missed, reducing the integrity of the harvest. In addition, since the original toggle bar is fixed at the bottom of the synchronous pulley, its position cannot be flexibly adjusted according to the terrain or the degree of plant lodging, further limiting its adaptability.

[0003] To address these issues, there is an urgent need for an auxiliary structure that can dynamically adapt to the varying states of garlic sprouts falling over. This auxiliary structure, while working in conjunction with the spacing adjustment function of the clamping mechanism, ensures synchronous movement when adjusting the row spacing and avoids structural interference. To this end, the present invention, based on the existing clamping device, proposes a height-adjustable hawk beak structure that moves synchronously with the row spacing to address the clamping problem of falling garlic sprouts. Summary of the Invention

[0004] In order to make up for the deficiencies in the prior art, the present invention provides a garlic harvesting and clamping device with an eagle beak structure.

[0005] A beak structure on a garlic harvesting clamping device, comprising a garlic harvesting clamping device, characterized in that: The garlic harvesting and clamping device is composed of a plurality of single clamping mechanisms arranged side by side. The single clamping mechanisms are used to clamp the garlic sprouts and lift the garlic for harvesting. The spacing between adjacent single clamping mechanisms can be changed. An eagle's beak structure is provided on each single clamping mechanism. The eagle's beak structure is used to straighten the garlic sprouts that have fallen to the ground, making it easier for the single clamping mechanism to clamp them.

[0006] Furthermore, in order to better implement the present invention, a gantry-type mounting frame is fixedly connected to the upper front end of the single clamping mechanism, and hawk's beak mechanisms are fixedly connected to both sides of the mounting frame.

[0007] Furthermore, in order to better implement the present invention, the hawk's beak mechanism includes a telescopic structure fixedly connected to the mounting frame, and a wedge is fixedly connected to the bottom of the telescopic structure. When the bottom of the wedge is touched to the ground, the fallen garlic sprouts can be straightened.

[0008] Furthermore, in order to better realize the present invention, the telescopic structure includes a fixed tube bolted or welded to the side of the mounting frame, the bottom of the fixed tube is slidably connected to the telescopic rod, the bottom of the telescopic rod is fixedly connected to the wedge block, a threaded hole is opened in the center of the upper and middle part of the telescopic rod, the threaded hole is threadedly connected to the screw, the upper part of the screw is rotatably connected to the fixed tube through a bearing, and the part of the screw extending out of the fixed tube above the screw is horizontally bent to serve as a handle.

[0009] The beneficial effects of the present invention are: The innovative hawk's beak structure forms a guide surface with its bottom wedge contacting the ground, gradually lifting fallen garlic seedlings from the bottom up. This improves efficiency compared to traditional vertical levers. A threaded telescopic adjustment mechanism allows the operator to continuously adjust the height of the wedge by rotating the handle, precisely adapting to varying degrees of lodging and terrain. The hawk's beak and clamping mechanism utilize a modular design. When adjusting the spacing of the individual clamping mechanisms, the hawk's beak moves synchronously with the mounting frame, maintaining the optimal working distance and preventing mechanical interference.

[0012] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in a variety of different configurations.

[0013] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but is merely intended to represent selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0014] Figures 1-4 This embodiment provides a garlic harvesting clamping device with a beak structure. This device is primarily used in the sandy loam soils of the Huanghuaihai region, the main garlic-producing region. During implementation, first, secure the gantry-type mounting frame 101 vertically to the front end of the frame of the single clamping mechanism 1 using M12 high-strength bolts, ensuring that the bottom of the mounting frame is 35 cm above the ground. Two sets of fixing pipes 201 are symmetrically welded to either side of the mounting frame 101. These fixing pipes are Φ50 x 3 mm galvanized steel pipes, with their axes forming a 75° angle with the ground.

[0015] Based on the field's lodging conditions (this example simulates a situation where 30% of the plants have a lodging angle greater than 45°), the operator pre-adjusts the screw 204 by rotating the L-shaped handle. Clockwise rotation causes the screw 204 to extend the telescopic rod 202 axially along the fixed tube 201. Once the wedge 203 contacts the ground, it rotates another quarter turn, generating a 5kgf preload to ensure operational stability. Field measurements show that in this position, the wedge's base effectively penetrates the ground by 2cm, effectively breaking up the surface compaction layer.

[0016] During harvesting, the tractor moves at a speed of 0.8 m / s, and the cutting edge of wedge 203 first contacts the fallen garlic stems. A 5 mm rounded arc on the upper portion of the wedge's working surface smoothly guides the grounded stems onto the 45° inclined guide surface. When the stems rise to a height of 15 cm along the inclined surface, they enter the range of the rubber toggle (described in Patent No. 202411444362X), achieving secondary righting. This dual-stage righting system improves the success rate of righting the stems.

[0017] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not limiting. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
