Description

Technical Field

[0001] The utility model relates to the technical field of tobacco leaf harvesting, in particular to a three-edged high-efficiency leaf scraper. Background Art

[0002] The tobacco leaf scraper that scrapes tobacco leaves off the tobacco plants is the core component of the tobacco leaf scraper (harvester). The harvester moves in the furrows, and the tobacco plants in the entire ridge pass through the middle of the two parallel-mounted leaf scrapers one by one. When passing each tobacco plant, the two parallel leaf scrapers rotate in opposite directions from both sides close to the tobacco stems (rods), forming a physical action of scraping the tobacco leaves downward synchronously on the left and right sides. The tobacco leaves within the scraper's operating range are scraped off from the petiole and fall off. The fallen tobacco leaves are caught by the harvester's conveying platform and transported into the harvester's storage device.

[0003] The tobacco leaves grow naturally in a 360-degree distribution with the tobacco stem as the center. The harvester moves forward along the tobacco ridge. After each tobacco tree arranged in a straight line on the tobacco ridge, the leaf scraper needs to pick the tobacco leaves distributed 360 degrees horizontally (left and right), vertically (front and back), and diagonally (diagonally at the four corners). Missing the leaves will cause losses to tobacco farmers. At the same time, the integrity of mechanized tobacco leaf harvesting is an extremely important indicator. Only when the leaves are in good condition can the purchase price and grade of tobacco leaves in the later stage be not affected. The greater the degree of damage to the leaves, the greater the loss to tobacco farmers. At present, tobacco planting and production are distributed in remote areas of my country, and the maintenance and guarantee capabilities of agricultural machinery are relatively weak. In particular, the continuous high-intensity operation throughout the harvesting season has high requirements for the reliability, maintainability, and simplicity of disassembly and recovery of the cutter body. A good cutter body is an important guarantee for whether the harvester can achieve efficient harvesting operations.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] like Figures 1 to 4 As shown, a three-edge high-efficiency scraper provided in this embodiment includes: a first shaft body 1A, a second shaft body 1B, a first single blade a2, a first single blade b3, a first single blade c4, a second single blade a5, a second single blade b6, and a second single blade c7.

[0035] Among them, the first shaft 1A and the second shaft 1B are parallel and arranged side by side left and right, the first single pole a2, the first single pole b3 and the first single pole c4 are evenly distributed clockwise on the first shaft 1A, and the second single pole a5, the second single pole b6 and the second single pole c7 are evenly distributed counterclockwise on the second shaft 1B; and the distribution of the first single pole a2, the first single pole b3 and the first single pole c4 on the first shaft 1A corresponds one to one to the distribution of the second single pole a5, the second single pole b6 and the second single pole c7 on the second shaft 1B. The first shaft body 1A and the second shaft body 1B rotate in opposite directions. The first shaft body 1A rotates clockwise and the second shaft body 1B rotates counterclockwise. When the first single blade a2 and the second single blade a5 rotate to be directly opposite to each other between the first shaft body 1A and the second shaft body 1B, they gradually separate. Then, the first single blade c4 and the second single blade c7 rotate to be directly opposite to each other and gradually separate. Then, the first single blade b3 and the second single blade b6 rotate to be directly opposite to each other and gradually separate. This cycle is repeated to harvest tobacco leaves on the tobacco stems.

[0036] In order to better harvest tobacco leaves and ensure that there is no missing in the 360-degree range, the first single blade a2 and the second single blade a5 are in a straight line on the side away from the corresponding first shaft 1A and the second shaft 1B, the first single blade b3 and the first single blade c4 are in a curve on the side away from the first shaft 1A, and the second single blade b6 and the second single blade c7 are in a curve on the side away from the second shaft 1B. When the first single blade b3 and the second single blade b6 and the first single blade c4 and the second single blade c7 rotate relatively to between the first shaft 1A and the second shaft 1B, the first single blade b3 and the second single blade b6, the first single blade c4 and the second single blade c7 are respectively meshed, as shown in FIG. Figure 2 and Figure 3 The first single blade a2 and the second single blade a5 harvest tobacco leaves on the left and right sides of the tobacco stem. When the first single blade a2 and the second single blade a5 rotate to the point where the first shaft 1A and the second shaft 1B are facing each other, there is a gap between the first single blade a2 and the second single blade a5. Figure 1 , the tobacco stem will not be damaged when the first single blade a2 and the second single blade a5 move relative to each other, and the tobacco leaves on the left and right sides can be quickly picked. The first single blade b3 and the second single blade b6, the first single blade c4 and the second single blade c7 harvest the tobacco leaves diagonally and in front and behind the tobacco stem, wherein the first single blade b3, the first single blade c4, the second single blade b6, and the second single blade c7 are away from the corresponding first shaft body 1A or the second shaft body 1B. The side of the wavy line with a concave-convex structure can ensure that no tobacco leaves are missed.

[0037] like Figures 1 to 4 As shown, the first single blade a2, the first single blade b3, the first single blade c4, the second single blade a5, the second single blade b6 and the second single blade c7 are provided with an arc-shaped introduction portion 8 along one end of the first shaft body 1A or the second shaft body 1B in the axial direction, which is used to guide the tobacco stems into the first shaft body 1A or the second shaft body 1B, so as to facilitate the non-damaged harvesting of all tobacco leaves within a 360-degree range around the specified height of the tobacco stems. At the same time, in order to better ensure the integrity of the harvested tobacco leaves and reduce or avoid leaf damage, the first single blade a2, the first single blade b3, the first single blade c4, the second single blade a5, the second single blade b6 and the second single blade c7 are all made of wear-resistant rubber materials, which can take into account the low damage of the blade at a low linear speed and ensure the mechanized harvesting efficiency.

[0038] like Figure 4 As shown, in this embodiment, the first shaft body 1A and the second shaft body 1B are both combined shafts, and are respectively composed of a fan-shaped shaft body a11, a shaft body b12 and a shaft body c13, and fastening rings 9 are provided at both ends of the shaft bodies a11, b12 and c13 for fastening them together, and fastening grooves 15 for embedding the fastening rings 9 are provided on the outer side surfaces at both ends of the shaft bodies a11, b12 and c13, which are convenient for installation and fastening.

[0039] At the same time, the shaft a11, shaft b12 and shaft c13 are equally divided by the axis, that is, the first single pole a2, the first single pole b3 and the first single pole c4 are evenly distributed at 120 degrees to each other, and the second single pole a5, the second single pole b6 and the second single pole c7 are evenly distributed at 120 degrees to each other.

[0040] Among them, the shaft a11 is provided with a mounting groove 14 for installing the first single blade a2 or the second single blade a5, the shaft b12 is provided with a mounting groove 14 for installing the first single blade b3 or the second single blade b6, and the shaft c13 is provided with a mounting groove 14 for installing the first single blade c4 or the second single blade c7; all the single blades are fastened in the corresponding mounting grooves 14 by screws, which is convenient for disassembly and installation, and can ensure the use strength of each single blade, thereby improving the harvesting efficiency.

[0041] The scraper adopts a three-dimensional design, based on a triangular structure, and is designed with three integrated combined blade bodies, corresponding to horizontal (left and right), oblique (four corners oblique) and front and back tobacco leaf harvesting; a combined shaft design is used, and according to the three groups of single blade installation positions, installation grooves 14 and installation screw holes are processed on the combined shaft, and fastening grooves 15 are processed at both ends of the combined shaft, and fastening rings 9 are used for locking. The single blade is made of wear-resistant rubber material, the combined shaft is made of wear-resistant carbon steel, the screws for installation and fixing are made of low-carbon steel, and the fastening ring 9 is made of stainless steel.

[0042] The use of the cutter body is to install the assembled left and right cutter bodies in parallel on the harvesting position of the harvesting vehicle, and the tail ends of the left and right shafts are respectively connected to the synchronous DC servo drive motors. According to the single-pole pairing combination requirements on the left and right cutter bodies, the single poles on the left and right cutter bodies are combined and aligned one by one.

[0043] During harvesting operation, the left and right cutters are driven by synchronous DC motors. Figures 1 to 3 The arrows in the middle indicate the direction of synchronous operation, rotating 0 degrees (the first single-pole a2 and the second single-pole a5, as shown in FIG. Figure 1 ), rotate to 120 degrees (the first single-pole c4 and the second single-pole c7, such as Figure 3 ), rotate to 240 degrees (the first single-pole b3 and the second single-pole b6, such as Figure 2 ), rotate to 360 degrees (the first single blade a2 and the second single blade a5, such as Figure 1 ) runs one circle and returns to 0 degrees, and repeats this process to harvest all tobacco leaves in the full range of the harvesting tool body. The combined tool body composed of multiple knives of the present invention can harvest tobacco leaves growing in all directions at 360 degrees, and can avoid loss due to missed harvesting.

[0044] The operation of the harvester focuses on efficiency. Compared with traditional tools, the leaf scraper rotates three pairs of single blades once a week to scrape and harvest three times in total, which is one more time compared with traditional tools. Under the maximum constant speed to control damage (if the blade rotates too fast, it will break the leaves it contacts. In order to reduce the damage of tobacco leaves, the speed of the blade drive motor has an upper limit, and the upper limit is the maximum constant speed), the harvesting efficiency is increased by 1.5 times, increasing the harvesting efficiency without causing additional tobacco leaf breakage rate.

[0045] At the same time, the scraper blade continuously rubs against the tobacco plant with high intensity all day long, and its strength requirements are very high. In particular, the rotation axis must be stable. If the rotation axis is twisted by external force, the blade body will be damaged; if the single blade is not installed firmly, it is also very easy to fall off. The combined shaft integrated design adopted by the present invention has high strength and stable axis, making the drive more stable and smooth; the single blade is directly fastened to the inner side of the shaft body with screws, and then clamped and locked by the fastening ring 9, and the single blade is tightly combined with the shaft body with good firmness; at the same time, the maintenance and disassembly of the blade body does not require the help of any testing tools, and does not require professional technicians.

[0046] The leaf scraper adopts a combined structure, which is easy to assemble and disassemble, can fully and stably harvest tobacco leaves, avoids loss due to missed harvesting, and will not damage tobacco stems and leaves, with high harvesting effect.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
