Abstract

CARROT THINNING MACHINE consists of a machine that performs the carrot thinning process in a semi-mechanized way, saving the worker from manual labor and saving time in carrying out the process. Operating in the area of agricultural implements, this equipment has the functions of removing excess carrot plants that have germinated in the bed and giving space to the plants that were not removed to develop more easily. It consists of an aluminum rod (1) fixed to a fixed cam shaft (3). Passing through the fixed cam shaft (3) we have a transmission shaft (5) to which is fixed a toothed disc (6) which consists of six metal springs (7) that are connected to six metal clamps (8) that move according to the rotation of the toothed disc (6) on the cams (4) and promote the opening and closing of the springs (7), removing the excess plants. Two drive wheels (9) are attached to the transmission shaft (5) which will transmit the rotary motion to the shaft. Each spring (7) is covered with a non-stick plastic substance (10) in the region that comes into contact with the plant vegetation, the hermetic insulating character promoted by the contact of the plastic helps in the removal of the plants. Which makes (...).

Claims (5)

  1. 1- CARROT THINNING MACHINE, characterized by comprising: cable holder (1), chassis (2), cam holder (3), cams (4), transmission shaft (5), toothed disc (6), elastic elements (7), clamps (8), drive wheels (9), clamp rubber (10) and bearings (11). The cable holder (1) is fixed to the chassis (2) by means of screws and has articulated movement. The chassis (2) has a rectangular shape with a circular opening to accommodate the cam holder (3) and another semicircular opening to accommodate the cable holder (1). The transmission shaft (5), to which the drive wheels (9) and the toothed disc (6) are fixed, has the function of transmitting the mechanical force provided by the rotation of the two drive wheels (9) to the toothed disc (6), which in turn will also move. This movement will be responsible for providing contact between the clamps (8) and the cams (4), causing the opening. and the closing of the elastic elements (7), and consequently the opening and closing of the clamps (8) with the function of holding the seedlings and pulling them out according to a cyclic movement.
  2. 2- CARROT THINNING MACHINE, according to claim 1, characterized by comprising a quadrangular cam holder (3) with four holes at its ends through which screws are placed that will fit the holder to the chassis (2) which has four arc-type openings with possible angle adjustments that allow advancing or delaying the opening of the clamps (8) in relation to the ground, the chassis (2) also having a central circular opening through which the cams (4) pass.
  3. 3- CARROT BURNTING MACHINE, according to claim 1, characterized by comprising a cam (4) in cylindrical shape with a wavy ridge on the edge which, in contact with the grippers (8) through the movement of the toothed disc (6), promotes the opening and closing of the elastic elements (7) and the grippers (8).
  4. 4- CARROT THINNING MACHINE, according to claim 1, characterized by comprising a toothed disc (6) to which is fixed the transmission shaft (5) which is constituted by six elastic elements (7) which through the contact between the clamps (8) and the cams (4) open and close capturing the carrot seedlings and through the displacement movement of the machine will promote the uprooting of the seedlings from the soil.
  5. 5- CARROT THINNING MACHINE, according to claim 4, CHARACTERIZED by comprising two layers of rubber gripper (10) which are fixed, each layer, to one end of the grippers (8) and the toothed disc (6) in the region of contact with the seedling to facilitate the removal of the same and improve the performance of the machine.

Description

FIELD OF THE INVENTION [001] The present invention consists of a machine that performs the process of thinning carrots in a semi-mechanized way, saving the worker from employing manual labor and saving time in carrying out the process. Presentation of the invention or field of application [002] In rural areas, many farmers face problems in the production of their legumes, especially carrots (Daucurus carota), a legume with high nutritional value rich in beta-carotene and vitamin A. Unlike some crops, carrot cultivation must take into account the spacing between each plant to ensure the full development of the vegetable. Currently, there is little equipment available for precise carrot sowing, since the seed is very small and there are no distributor discs on the market with sufficient precision to provide adequate sowing, often resulting in sowing being done by hand, placing excess seeds. [003] This scenario shows the need for an intermediate operation between sowing and harvesting, known as thinning. Thinning is a technique that aims to remove excess plants from the soil so that the remaining plants can develop satisfactorily without competing for nutrients with each other. In this way, plants that grow in adequate space in the beds are much larger and more economically attractive than plants where the thinning process has not been carried out. Currently, thinning is an activity performed manually in the field. [004] The present invention aims to perform the operation of thinning carrots in a semi-mechanized way in the field. This eliminates much of the physical effort used by the farmer, who is forced to squat and bend over to perform the activity. The invention is easy to handle, consisting of a handle connected to a set of mechanisms that open and close clamps that pull and uproot some plants from the soil, leaving others that will develop. It is aimed at the agricultural sector, especially small farmers and family farms. STATE OF THE ART [005] Carrots are considered one of the most consumed vegetables in the world because they are rich in vitamin A, a nutrient that aids in body growth, improves vision, maintains the integrity of epithelia (cells that line the body and form a barrier against infections), and supports skeletal growth and development. This nutrient also has antioxidant properties, combating aging and cancer, and preventing chronic diseases such as cataracts, arthritis, and cardiovascular diseases. Being one of the foods richest in beta-carotene, a substance that converts to vitamin A in the body, and being highly palatable, its consumption is almost daily, both in Brazil and abroad. An adult needs a daily intake of 400 to 700 μg of this vitamin, with a medium-sized carrot providing 509 μg. [006] Although there are records of machines that perform the carrot sowing operation in the field, they do not guarantee a fixed spacing between plants because the seeds are very small, only ensuring that the sowing is done linearly. Sowing can also be done manually by workers who scatter excess seeds on the ground to ensure germination and emergence. As there is no uniformity in the execution of sowing, the seedlings that emerge do not have a fixed growth pattern, which can result in carrots of very different sizes and, in more serious cases, when many carrot seedlings are sown in the same place, they compete with each other for nutrients, which can lead to the growth of smaller plants. [007] To overcome this problem, a process of removing excess sprouted carrot seedlings called thinning is carried out. The process is done manually by workers who bend down to remove the carrots. In addition to being a risky activity, completely unhealthy because it exposes the worker to great effort to remain crouched while performing the work, it is also an activity that demands a lot of time to be carried out, since the worker needs to walk in a squatting position to do so. [008] It is important to emphasize that the carrot production process takes place in different stages: Preparation of the seedbed, sowing, cultural practices (thinning), harvesting of the production. [009] The present invention is intended to act in the cultural practices stage of carrots, where the process of thinning the carrots is carried out. Thinning is nothing more than the removal of excess plants that have germinated in the bed in order to give the remaining plants more space to develop and less work to capture nutrients from the soil. [010] It is important to emphasize that the machine only operates in the legume thinning process, and should not be used to remove the plant in its final stage of harvesting, as this will require much more force to remove it. [011] Thus, the machine presents itself as an invention because it covers a specific stage of the carrot production process that is not carried out by any of the mechanized and semi-mechanized carrot seeders and harvesters currently on the market.
