Description

Technical Field

[0001] This utility model relates to a potato vine-killing machine, specifically a vine-pulling device for a potato vine-killing machine. Background Technology

[0002] This process is used to shred straw and weeds in the furrows and ridges of potatoes before harvesting, preventing straw tangling and ensuring smooth operation of the potato harvester. Shredding not only improves potato yield and harvesting efficiency, and ensures quality, but also allows the straw to be returned to the field, maintaining soil fertility.

[0003] Currently, the main methods for potato vine killing are mechanical and chemical. Mechanical vine killing uses vine-killing machines, such as the potato vine-killing machine for hilly areas disclosed in Chinese utility model patent CN216087657U. This machine has a vine-supporting mechanism, which includes a vine-supporting rod and a vine-topping blade. The vine-supporting rod lifts the vines on both sides of the ridge, and the vine-topping blade cuts off the top vines. However, the vine-topping blade in existing technology is not very effective at cutting vines, easily missing some, and some vines even pass over the sides of the blade. Furthermore, the vine-supporting rod is fixed to the rotating roller and cannot be adjusted to adapt to the terrain. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a vine-pulling device for a potato vine-killing machine that offers good top-cutting effect and adaptability to different ridge types.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A vine-cutting device for a potato vine-killing machine includes a rotating roller and vine-cutting teeth disposed at both ends of the rotating roller. A plurality of vine-cutting blades are fixedly disposed on the outer surface of the middle section of the rotating roller. The vine-cutting blades extend along the axial direction of the rotating roller, and the plurality of vine-cutting blades are arranged in a circumferentially at equal intervals on the outer surface of the rotating roller.

[0007] Furthermore, the cutting blade is fixed to a sleeve, which is detachably connected to the rotating roller.

[0008] Furthermore, the cutting blade is a spiral strip extending along the axial direction of the rotating roller.

[0009] Furthermore, the seedling-pulling teeth are pull rods.

[0010] Furthermore, a plurality of threaded holes are provided on the surface of the rotating roller, and the end of the lever is provided with a threaded end that mates with the threaded holes.

[0011] Furthermore, a sliding seat is provided on the surface of the rotating roller, at least one end of the sliding seat is not closed, and a slider is provided at the end of the lever inside the sliding seat. The sliding seat is provided with a plurality of limiting holes I, and the slider is provided with a limiting hole II corresponding to the limiting hole I.

[0012] The beneficial effects of this utility model are:

[0013] Its cutting blades are designed to completely remove seedlings from the top of the ridge without any omissions; moreover, all the cutting blades are fixed to the sleeve, allowing for quick installation and removal from the rotating roller, making it convenient to use. The seedling-pulling teeth are mounted on the surface of the rotating roller via sliding seats, allowing for quick adjustment of their position according to the ridge width, and different lengths of seedling-pulling teeth can be replaced as needed.

[0018] To enable those skilled in the art to better understand the present invention, the following will describe the embodiments of the present invention in conjunction with the appended descriptions. Figure 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0019] The first embodiment of this utility model:

[0020] The potato vine-cutting machine of this utility model includes a rotating roller 1 and vine-cutting teeth disposed at both ends of the rotating roller 1, wherein the vine-cutting teeth are preferably vine-cutting rods 2. The rotating roller 1 includes a central shaft, one end of which is connected to a power source via a transmission pulley or gear, and the other end is mounted on the vine-cutting machine via a bearing seat. A plurality of vine-cutting blades 3 are fixedly disposed on the outer surface of the middle section (i.e., the middle position) of the rotating roller 1, the vine-cutting blades 3 extending along the axial direction of the rotating roller 1, with a length of approximately 30-60 cm. The plurality of vine-cutting blades 3 are arranged circumferentially at equal intervals on the outer surface of the rotating roller 1. As a preferred method, such as... Figure 1 As shown, the cutting blade 3 is a spiral strip extending along the axial direction of the rotating roller 1.

[0021] To facilitate disassembly and installation, the cutting blade 3 is fixed to a sleeve 4, which is detachably connected to the rotating roller 1. Specifically, a through hole is provided on the sleeve 4, and a threaded hole corresponding to the through hole is provided on the rotating roller 1. The two are then fixedly connected by hexagonal socket head cap screws. Alternatively, those skilled in the art can provide a key on the rotating roller 1 and a keyway on the inner wall of the sleeve 4, thereby making the fit between the sleeve and the rotating roller more stable. The cutting blade 3 of this invention can be directly welded to the sleeve 4, or a fixing ear plate can be provided at the bottom of the cutting blade 3 and fixed to the sleeve 4 by bolts.

[0022] During operation, the rapidly rotating cutting blade 3 contacts the potato vines and cuts them. The height of the cutting blade 3 off the ground is adjusted by the support wheels on the vine-cutting machine (e.g., ...). Figure 3 As shown on the left, this part belongs to the prior art and will not be described further.

[0023] Since the width and height of the ridges may vary among different growers, in order to make the lever 2 better adapt to the ridge shape, this utility model can adjust the position of the lever 2 and replace the lever 2. This utility model provides several threaded holes 101 on the surface of the roller 1 along the axial direction of the lever 2 installation, and the end of the lever 2 is provided with a threaded end that mates with the threaded holes 101.

[0024] like Figure 3 As shown, this utility model is installed in front of the seedling crushing roller 6 of the seedling killer. One end of the rotating roller 1 is connected to the power source of the seedling killer through a chain or transmission belt. During operation, the seedling cutting blade 3 cuts the seedlings at the top of the ridge, and the lever 2 picks up the seedlings on both sides of the ridge and puts them into the seedling crushing roller 6.

[0025] As a second embodiment of this utility model:

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] Considering that the lever 2 in the first embodiment is inconvenient to disassemble and install, and that the threaded end and threaded hole are prone to deformation under stress after long-term operation, making disassembly even more difficult, the connection between the lever 2 and the sleeve in the first embodiment is designed as follows:

[0029] A sliding seat 5 is welded or bolted to the surface of the roller 1. At least one end of the sliding seat 5 is not closed, such as... Figure 2 As shown, neither end of the sliding seat 5 is closed, making it resemble a C-shaped groove. A slider 201 is located within the sliding seat 5 at the end of the lever 2. The sliding seat 5 has multiple limiting holes I 501, and the slider 201 has a limiting hole II corresponding to the limiting hole I 501. After the limiting holes I 501 and II are aligned, the slider 201 and the sliding seat 5 are fixedly connected by screws. To adjust the position of the lever 2, loosen the screws, adjust it to the appropriate position, and then tighten them again. To replace the lever 2, simply push the slider 201 out from any port of the sliding seat 5.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
