Description

TECHNICAL FIELD

[0001] The present invention relates to agricultural machines and their tools. More specifically, it relates to a backpack- and vacuum-assisted cotton harvester that reduces farmers' efforts to harvest mature cotton in the shortest possible time. BACKGROUND

[0002] The traditional method of cotton harvesting is too time-consuming. It requires a large number of workers to pick the ripe cotton individually. Sometimes, the sharp edges of the branches / leaves can injure the workers' skin. Heavy machinery is not suitable for smallholder farms to harvest ripe cotton precisely. The traditional harvesting method is labor-intensive and can affect overall profits. On the other hand, proper separation of cotton from seeds helps increase productivity in the textile industry. There is no portable, vacuum-assisted cotton harvester on the market that can harvest the cotton immediately and classify it separately, reducing farmers' manual effort.

[0003] Therefore, there is a need for a backpack-type, vacuum-assisted cotton harvester that reduces manual effort and losses while increasing harvest yield. The present invention effectively overcomes the above-mentioned problems, limitations, and disadvantages. OBJECT OF THE INVENTION

[0004] The main objective of the present invention is to provide a backpack-type vacuum-assisted cotton harvester that reduces manual effort in harvesting mature cotton.

[0005] Another object of the present invention is to prevent accidents of workers during manual harvesting of cotton from cotton balls.

[0006] Another object of the present invention is to reduce cotton loss during manual harvesting.

[0007] Another object of the present invention is to increase the yield by properly extracting the mature cotton from the respective plant.

[0008] Another object of the present invention is to provide a battery-operated device for harvesting mature cotton by means of a vacuum.

[0017] The various embodiments, as well as further developments and features, are explained in the following detailed description with reference to non-limiting details. The depiction of processing techniques for known components is omitted in order not to unnecessarily obscure the embodiments described herein. The examples used herein are intended to facilitate understanding of the possible applications of the embodiments described herein and to enable those skilled in the art to implement the embodiments described herein. The examples should therefore not be construed as limiting the scope of application of the embodiments described herein.

[0018] The various embodiments of the present invention describe a backpack-type, vacuum-assisted cotton harvester (15) that reduces manual effort and losses during manual harvesting of mature cotton. The backpack-type, vacuum-assisted cotton harvester consists of a power source, a fiber sheet container, a nozzle, a blower, a cotton stalk holder, a wooden roller, and a filter. The battery power source (2) supplies the device with the necessary energy. The fiber sheet container is configured to be carried by the wearer on the shoulder using a strap / belt. The fiber sheet container (7) serves to store the harvested cotton inside. The strap can be attached to the front or back of the container.

[0019] Fig.shows an isometric view of the backpack-style, vacuum-assisted cotton harvester according to an embodiment of the present invention. The cotton stem holder positions the harvesting edge of the device for picking the mature cotton using the vacuum source. The cotton stem holder (9) helps remove unwanted material from the suction area. This removal or pushing action helps ensure the desired harvest quality. The blower (4) uses the nozzle rim and cotton holder positioning to create the negative pressure to suck the mature cotton from the selected cotton balls. The negative pressure source is routed through the flexible line to suck the cotton from the plant.

[0020] The filter (6) stops the sucked-in cotton and directs it from the nozzle to the fiberboard container. The filter prevents the cotton from moving inside the blower. The filter consists of a wire mesh that directs the cotton to the inside of the container. Dust particles can pass through the wire mesh and be removed separately. The filter is located between the nozzle and the blower.

[0021] The wooden roller (11) is positioned at an angle at the bottom of the container and rotates in opposite directions. The motor of the wooden roller separates the cotton from the seeds by passing the harvested cotton through the wooden rollers. The extracted cotton is stored in a cotton outlet. The rollers are arranged parallel to each other and at an angle.

[0022] The motor (12) with gears rotates the rollers in opposite directions. This causes the harvested cotton to pass through the rollers into the storage area, while the seeds move to the lower edge of the inclined area. The seed hopper is located at the bottom of the inclined rollers. It collects and stores the seeds filtered by the rotating rollers. Farmers can remove the seeds for later use.

[0023] The flexible hose (1) connects the nozzle and blower to suck in the mature cotton from different directions. The harvester is operated via an on / off switch. The container has a lid at the top that can be opened to manually fill / clean the cotton as needed. The filter (6), made of wire mesh, filters the waste and directs the cotton into the container.

[0024] The cotton stem holder (9) can be attached to any side of the nozzle to harvest cotton using the vacuum source. It prevents leaves, stems, or bark from moving toward the nozzle when the cotton is vacuumed from the plant. The wooden roller (11) can be moved in the opposite direction to classify seeds and cotton using the motor rotation. The strip length can be manually adjusted to increase or decrease the backpack height as needed.

[0025] In one embodiment, the cotton picker is equipped with an electric motor (12) connected to the bottom of the container (7). The blower (4) is connected to the battery (2). The filter (6) is located parallel to the fiberboard container (7). The container (7) serves to hold / place the cotton inside. The container (7) has a filter (6) that prevents cotton from entering the blower (4). The suction power of the blower (4) is transmitted through the filter (6). The flexible hose (1) serves to suck up the cotton inside. The cotton picker consists of two gears in two wooden rollers (11) connected to the electric motor (12). The power transmission between the gears causes the rollers to roll and the ginning process.

[0026] In one embodiment of the present invention, the electric motor (12) is stationary. The motor (12) is connected to a gear that transfers the power into the rotational movement of the roller.

[0027] According to one embodiment of the present invention, the fan (4) is connected to the battery (2) to ensure the suction process. The fan (4) is in turn connected to a filter (6).

[0028] According to one embodiment of the present invention, the wooden rollers (11) are connected to a gear that takes over the power transmission of the motor (12).

[0029] In one embodiment, the machine (15) requires suction power to collect the cotton. The fan generates suction pressure on one side and blows out air. Using this suction pressure, the machine harvests the ripe cotton.

[0030] The vacuum-assisted cotton harvester simplifies cotton harvesting by combining harvesting and ginning into a single, efficient system. Using vacuum suction, the cotton is harvested directly from the field and processed in a single operation. This integration reduces manual labor, saves time, and improves overall efficiency. The machine is user-friendly, making it suitable for both small and medium-sized farms.

[0031] The harvester (15) effectively separates cotton fibers from the seed using ginning rollers, ensuring high-quality cotton production. The rollers efficiently extract the cotton while minimizing the ingress of unwanted foreign particles. The result is a cleaner, higher-quality product, essential for textile processing and other post-harvest applications. The automated ginning process minimizes waste and increases productivity.

[0032] The device (15) is powered by a single battery. The machine is energy-efficient and highly mobile, making it ideal for use in remote agricultural areas. Both the extraction and ginning functions are powered by the same power source, reducing energy consumption and ensuring smooth operation. The battery-powered design also offers an environmentally friendly alternative to fuel-powered machines, contributing to reduced CO2 emissions and operating costs.

[0033] The motor (12) transmits power via a gear to the roller gear train, driving the rollers critical for the ginning process. The motor's mechanical energy is effectively transferred through the gears, allowing the rollers to rotate efficiently and separate the cotton fibers from the seeds. The vacuum system assists the cotton by pulling it from the plants, improving the overall harvesting process and reducing damage. After harvesting, the cotton passes through the rollers, where the ginning process takes place, separating the fibers from the seeds. This makes the machine an effective tool for cotton cultivation and processing.

[0034] The machine (15) is lightweight and easy to move, allowing it to be easily transported from one location to another. This portability is particularly advantageous in mid-altitude fields, where cotton harvesting can be more difficult. The present invention reduces the need for skilled labor and the time required for cotton harvesting.

[0035] The examples of the present invention described above are for illustrative purposes only. Although the present invention has been described using a specific example, numerous modifications are possible without substantially departing from the teachings and advantages of the subject matter described herein. Further substitutions, modifications, and changes are possible without departing from the spirit of the present solution. All features disclosed in this description (including the appended claims, the abstract, and the drawings) and / or all steps of a method or process disclosed therein may be combined in any way, except for combinations in which at least some of these features and / or steps are mutually exclusive.

[0036] Although the embodiments described herein are described with reference to various specific embodiments, it will be understood by those skilled in the art to implement the embodiments described herein with modifications.
