[0002] PNEUMATIC SAFFLOWER HARVESTING MACHINE

[0003] Technical Field of the Invention

[0004] The invention relates to a field-type pneumatic safflower harvesting machine, which can be mounted on a tractor and harvests thorny and / or thornless safflower flowers by means of a hydraulic system with negative-pressure air.

[0005] State of the Art

[0006] The safflower plant (Carthamus tinctorius L.) is an annual and dry farming crop. The safflower plant has both thorny and thornless forms, with the thorny forms containing more oil than the thornless ones. The plant blossoms with flowers in various colours such as yellow, white, cream, red and orange. Its seeds are generally white, cream- coloured, or white grains with dark stripes, while black seeds are rarely found. By means of its branching structure, the plant forms small heads at the ends of each branch where the seeds are located. These colourful flowers (petals) are used in food and textile dyeing. This plant, which has a taproot system capable of reaching deep into the soil, contains 30-50% oil in its seeds, which is divided into linoleic (Omega-6) and oleic (Omega-9, olive-oil quality) fatty acids. Its oil is of edible quality and is also used in biodiesel production. The safflower plant’s pulp is utilised as animal feed. Due to its drought resistance, summer cultivation characteristics, and its ability to mature in approximately 110-140 days, it plays an important role in agriculture as an annual long-day oil crop.

[0007] Safflower flowers have traditionally been widely used in the Middle East, India, China and the Mediterranean region. At present, however, it is cultivated worldwide, particularly in regions with arid and semi-arid climates. In Turkiye, safflower cultivation is widely practised in Central Anatolia, Southeastern Anatolia and the Aegean regions. In addition to obtaining oil from the seeds of the safflower plant and using it as biofuel, safflower oil is preferred in cosmetic and skincare products due to its moisturising and antioxidant properties. The safflower flower, with its yellow and red pigments, is used as a food colouring. In traditional medicine, the safflower flower has been recommended for improving blood circulation, reducing inflammations and treating various ailments. The stems and leaves remaining from the safflower plant are utilised as animal feed.

[0008] Although the safflower plant is used in many areas, harvesting its flowers is difficult due to its thorny structure. The safflower flower reaches harvest maturity 7-10 days before seed harvesting. Therefore, there is only a short period for harvesting. Safflower flowers are harvested by hand and with machines carried on the back. While in countries such as India, China and Iran small portable machines carried on the back are used, in Turkiye they are harvested by hand. The harvesting of safflower seeds, on the other hand, is carried out with combine harvesters.

[0009] Although various proposals and applications have been developed for safflower harvesting machines and pneumatic harvesting machines in the state of the art, these developments are not sufficient. Some applications concerning inventions developed for this purpose are given below.

[0010] In the state of the art, the invention disclosed in application No. CN204741843U relates to a portable safflower harvesting machine with a harvesting and holding mechanism, which is suitable for collection machines that cut dried flowers or flowers with a blade, and belongs to the field of agricultural machine harvesting.

[0011] In the state of the art, the invention disclosed in application No. CN202773410U is concerned with the use of a cutting and harvesting mechanism for cutting fresh safflower filaments from their roots. A portable, single-person safflower harvesting machine, which is manually operated and equipped with a motor, is described. The harvesting mechanism connected to the cutting machine is linked to a pneumatic conveying mechanism, and the transport of the obtained filaments by means of negative pressure is described. The filaments tom off by friction between cylinders are pneumatically conveyed to the storage tank. In the state of the art, safflower harvesting machines are available. These machines have low work capacities and are suitable for use in small areas. However, there is no safflower harvesting machine that can be connected to a tractor by means of a three- point suspension system, and that harvests the flower without damaging it, without any physical (shaking) or chemical (defoliant) application, independent of human power, and with the colour of the flower preserved.

[0012] As a result, due to the drawbacks mentioned above and the inadequacy of current solutions regarding the subject matter, a development in the relevant technical field has become necessary.

[0013] The Aim of the Invention

[0014] The most important aim of the invention is to harvest the safflower flower without damage by means of negative pressure.

[0015] Another aim of the invention is its use together with a tractor. Thus, since the forward speed and the number of harvested rows are increased, harvesting is carried out in a short time.

[0016] Another aim of the invention is that the movement is performed by means of a hydraulic system. Thus, it becomes compatible with tractors of different sizes.

[0017] Another aim of the invention is the use of special headers for collecting the safflower flower. Thus, only the flower is collected without damage.

[0018] Another aim of the invention is to harvest the safflower plant by collecting only its flower by means of air.

[0019] Another aim of the invention is that there is no need for personnel for harvesting and for a person to operate the machine. Only a tractor driver is required. Description of Drawings

[0049] Description of the invention

[0050] The invention relates to a field-type pneumatic safflower harvesting machine, which can be mounted on a tractor and harvests thorny and / or thornless safflower flowers by means of a pneumatic system with negative-pressure air (vacuum).

[0051] The safflower harvesting machine is a harvesting machine that is connected to the tractor by means of a three-point suspension system, takes its motion from the power take-off shaft (20), transmits this motion to the fan shaft (21 ) through the hydraulic system (10) and the belt pulley system (18), collects and harvests safflower flowers in the headers by means of the negative pressure produced by the fan (7), and separates the flowers from the air in the cyclone (4).

[0052] Although oil is obtained from the seeds of the safflower plant, harvesting its flowers is difficult due to its thorny structure. Safflower flowers reach harvest maturity 7-10 days before seed harvesting. With the invention, rapid harvesting of safflower flowers is achieved without any discolouration, damage, or the like.

[0053] The invention harvests safflower flowers by using negative pressure, namely vacuum. The invention is connected to the tractor by means of a three-point suspension system. The motion taken from the power take-off shaft (20) of the tractor is increased by the hydraulic system (10) and the belt pulley system (18), and the rotary motion coming from the belt pulley system (18) is transmitted to the fan shaft (21 ), causing the fan (7) to rotate and thereby enabling the fan (7) to generate negative pressure. As the pressure source, a centrifugal (radial) fan (7) is used, and by means of this fan (7), negative-pressure air (vacuum) is generated. By means of the negative-pressure air formed, the harvesting header (1 ), which scans the safflower flower from above and from the sides, sucks in only the flowers on the safflower plant. The sucked flowers are collected into the cyclone (4), and with the conical structure of the cyclone (4) they are separated from the air and gathered in the cyclone (4). The cyclone (4) separates the safflower flowers carried with the air from the air by means of its expanding volume, accumulating the safflower flowers at the base, and allows the air to pass from the upper part of the cyclone (4) through the hose (6) to the fan (7). In addition, on the fan (7) there is a rain shield (8) which protects the fan (7) from external factors such as rain.

[0054] In Figure 1 , which shows the basic principle of the invention, the safflower flowers in the harvesting headers (1 ) are sucked in with vacuumed air at the air inlet (2). The safflower flowers sucked in by vacuum are conveyed within the pressurised air. The suction hoses (3) serve as channels conveying the pressurised air from the harvesting headers (1 ) to the cyclone (4). As the pressure source, a centrifugal (radial) fan (7) is used, and by means of this fan (7), negative-pressure air (vacuum) is generated. While the fan (7) sucks air from the harvesting headers (1 ), at the same time the sucked air is discharged into the atmosphere from the air outlet (9). In addition, on the fan (7) there is a rain shield (8) which protects the fan (7) from external factors such as rain. By means of the negative-pressure air formed, the harvesting header (1 ), which scans the safflower flower from above and from the sides, sucks in only the flowers on the safflower plant. The sucked flowers are collected into the cyclone (4), and with the conical structure of the cyclone (4), the safflower flowers are separated from the air and gathered in the cyclone (4). The cyclone (4) functions as a separator. The safflower flowers collected in the cyclone (4) are discharged from the harvest outlet (5), which is the material outlet located at the bottom of the cyclone (4) and equipped with a bolted, gasketed and air-tight discharge cover. The fan (7), which is the heart of the safflower harvesting machine, generates vacuum by sucking in air from the harvesting headers (1 ) and the air inlet (2) with the aid of the harvesting headers (1 ), suction hoses (3), cyclone (4) and hose (6). Thus, the collection of safflower flowers is ensured.

[0055] In Figure 2, the same parts as in Figure 1 are shown, and in addition, the general view of the safflower harvesting machine and the chassis (19), on which the main parts forming the safflower harvesting machine are mounted, are illustrated. Furthermore, Figure 2 shows the air and safflower flow direction in the safflower harvesting machine. The pressurised air and safflower flowers reach the cyclone (4) from the air inlet (2). In the cyclone (4), the safflower flowers are separated from the air and collected through the harvest outlet (5). The air, on the other hand, passes through the fan (7) by means of the hose (6) and is discharged into the atmosphere from the air outlet (9).

[0056] Figure 3(a) is a drawing showing the impeller of the fan (7) that generates the essential negative pressure inside the fan (7), Figure 3(b) is a drawing showing the side view of the fan (7) together with its connection to the fan shaft (21 ), and Figure 3(c) is a drawing showing the front view of the fan (7) together with the air outlet (9) and the rain shield (8).

[0057] Figure 4 shows the suction hoses (3), which enable the safflower flowers harvested by the harvesting headers (1 ) under the effect of vacuum pressure to be conveyed to the cyclone (4). The cyclone (4) separates the safflower flowers and the air coming from the suction hoses (3). Since the surface area with which the air comes into contact in the cyclone (4) increases, i.e. a volume expansion occurs, the safflower flowers, which have a greater critical velocity, accumulate at the base of the cyclone (4), while the air passes through the opening located at the upper part of the cyclone (4), goes to the fan (7) by means of the hose (6), and is discharged into the atmosphere from the fan (7) with the aid of the air outlet (9). The safflower flowers collected in the cyclone (4) are discharged from the harvest outlet (5), which is the material outlet located at the bottom of the cyclone (4) and equipped with a bolted, gasketed and air-tight discharge cover.

[0058] Figure 5(d) shows the front view of the harvesting header (1 ), and Figure 5(e) shows the side view of the harvesting header (1 ). These figures show that from the harvesting header (1 ), the air inlet (2) continues into the suction hoses (3). The invention comprises the speed increaser (11 ), hydraulic system (10), belt pulley system (18), centrifugal fan (7), cyclone (4), air transmission hoses (6), suction hoses (3), chassis (19) and the harvesting header (1 ). The hydraulic system (10) comprises the hydraulic pump (12), hydraulic hoses (13), filter (22), oil tank (14), pressure control valve (15), directional control valve (16) and hydraulic motor (17).

[0059] In the hydraulic system (10), the speed increaser (11 ) is connected to the power takeoff shaft (20) and triples the speed received from the power take-off shaft (20). The power take-off shaft (20) speed increased threefold, reaches the hydraulic pump (12), and the pump delivers oil into the system. The pump converts the mechanical energy received from the power take-off shaft (20) into hydraulic energy. The hydraulic hoses (13) are high-elasticity synthetic rubber hoses that provide smooth flow and are used to transmit the high-pressure oil between the hydraulic pump (12), the pressure control valve (15), the directional control valve (16) and the hydraulic motor (17). The filter (22) in the hydraulic system ensures the cleaning of the oil, holding contaminants and enabling the oil to perform its function more effectively. The oil tank (14) is a rectangular prism-shaped metal container in which the oil is stored, cooled and cleaned. The pressure of the oil delivered into the system by the hydraulic pump (12) is adjusted by the pressure control valve (15). The pressure-adjusted oil then enters the system. The hydraulic motor (17) is the point where the power is taken, converting the hydraulic oil pressure into rotational force at the motor shaft, i.e. converting the hydraulic energy supplied to the oil by the hydraulic pump into mechanical energy, thereby producing torque and consequently power, and driving the fan (7). Between the fan (7) and the hydraulic motor (17), the rotational speed produced by the hydraulic motor (17) is doubled by means of the belt pulley system (18). Thus, the rotational speed taken from the power take-off shaft (20) is once again increased by the hydraulic system (10) and the belt pulley system (18), resulting in a total increase of sixfold. The shaft of the hydraulic motor (17) is connected to the fan shaft (21 ) by means of a flange. The fan (7), operating at approximately 3000 rpm as shown in Figure 3, generates the negativepressure air, which is the fundamental element of the pneumatic system. The suction hoses (3) serve as channels conveying the pressurised air to the cyclone (4) and the harvesting headers (1 ). The cyclone (4), shown in Figure 4, with its inverted conical structure, separates the safflower flower from the air and ensures that the safflower flowers remain in the cyclone (4). The cyclone (4) functions as a separator. In principle, all materials carried by air are separated in the cyclone (4) because they are heavier than air (even dust is separated from air) and remain in the cyclone (4), while the air continues on its way. The harvesting headers (1 ), with their special design, come into contact with the plant and enable the flowers of the plant to be sucked in by vacuum.

[0060] Although the invention works on a single row, its work capacity is 30 kg / day. Compared with back-carried machines, the invention provides a superiority of 20-60 times, while compared with manual collection it performs in one day the work that one worker would complete in 60-120 days, thereby providing savings in time and cost.

[0061] With the invention, harvesting is carried out directly by vacuum, i.e. by means of negative pressure, and no mechanical tool or chemical aid such as a defoliant is used. The harvesting is performed by scanning the product on the plant from three directions with an inverted U-shaped header.

[0062] Any tractor carrying the hydraulic system (10) in a suspended manner can be used for operating the safflower harvesting machine. Work machines used with tractors (soil tillage, sowing, spraying, fertilising, harvesting machines, etc.) are manufactured either as suspended type connected to the three-point suspension system, or as towed type connected to the drawbar. This relates to the transport of the machine, while its motion or energy is taken from the power take-off shaft (20) of the tractor. The 450 rpm taken from the power take-off shaft (20) is transmitted as 2700 rpm to the fan shaft (21 ) by means of the hydraulic system (10) and the belt pulley system (18). Here, the hydraulic system (10) or the belt pulley system (18) is used as a power transmission and transfer element. The motion energy from the power take-off shaft (20) is converted into hydraulic energy and then reconverted into motion, i.e. mechanical energy, in the hydraulic motor (17). With this transmission and conversion, the rotational speed is increased sixfold, while the directional and distance advantages of the hydraulic system (10) in motion transmission are utilised.

[0063] The invention harvests safflower flowers by means of the harvesting header (1 ), which surrounds the flowers from the top and the sides, collects the flowers by means of the vacuum created by the fan (7), and conveys them to the suction hoses (3). The air inlet (2) is the point where the air, drawn from the atmosphere by the fan (7), enters the harvesting header (1 ) to collect and convey the safflower flowers, and the air together with the safflower flowers enters the pneumatic system from the harvesting header (1 ) by means of the vacuum effect. In the cyclone (4), the safflower flowers are separated from the air and remain in the cyclone (4), while the air passes through the fan (7) and is discharged from the air outlet (9). The suction hoses (3) enable the safflower flowers harvested by the harvesting headers (1 ) under the effect of vacuum to be conveyed to the cyclone (4). The cyclone (4) separates the safflower flowers and the air coming from the suction hoses (3). Since the surface area with which the air comes into contact in the cyclone (4) increases, i.e. a volume expansion occurs, the safflower flowers, which have a greater critical velocity, accumulate at the base of the cyclone (4), while the air passes through the opening located at the upper part of the cyclone (4), goes to the fan (7) by means of the hose (6), and is discharged into the atmosphere from the fan (7) with the aid of the air outlet (9). The safflower flowers collected in the cyclone (4) are discharged from the harvest outlet (5), which is the material outlet located at the bottom of the cyclone (4) and equipped with a bolted, gasketed and air-tight discharge cover. The hose (6), which provides the connection between the fan (7) and the cyclone (4), ensures that the air exiting the cyclone (4) is conveyed to the fan (7). The fan (7), which is the heart of the safflower harvesting machine, generates vacuum by sucking in air from the harvesting headers (1 ) and the air inlet (2) with the aid of the harvesting headers (1 ), suction hoses (3), cyclone (4) and hose (6). Thus, the collection of safflower flowers is ensured. The rain shield (8), located at the end of the air outlet (9) pipe and shaped like a cap, prevents rain and other materials from entering the fan (7) that may come from the environment and obstruct the discharge of air from the fan (7). The air outlet (9), which enables the air to be discharged from the fan (7) into the atmosphere, is also the part to which the rain shield (8) is connected. The speed increaser (11 ), which is connected to the power take-off shaft (20), which is the splined part where the tractor’s power output is made and which transmits the rotary motion taken from the tractor to the hydraulic pump (12) by means of the speed increaser (11 ), triples the speed taken from the power take-off shaft (20). The hydraulic pump (12), which receives the motion taken from the power take-off shaft (20) and transfers it to the hydraulic oil, draws oil from the oil tank (14) and delivers it to the hydraulic motor (17), thereby converting mechanical energy into hydraulic energy. The hydraulic hoses (13) transmit the hydraulic fluid that conveys the power. The oil tank (14), which stores the oil, also assists in cooling and cleaning the oil. The pressure control valve (15), which adjusts the pressure of the oil pumped into the system by the hydraulic pump (12), reduces the pressure by returning part of the oil to the tank when exposed to high pressure. The directional control valve (16), which gives direction and route to the oil pumped by the pump, is used in the system as a 4 / 3 (4-way, 3-position) type. The hydraulic motor (17), which converts the hydraulic energy of the oil coming from the hydraulic pump (12) into mechanical energy, drives the fan (7). The rotational speed obtained from the hydraulic motor (17) is doubled by the belt pulley system (18) and transmitted to the fan (7). The rotational speed taken from the power take-off shaft (20) is once again increased by the speed increaser (11 ) and the belt pulley system (18), resulting in a total increase of sixfold. The connection of the pneumatic safflower harvesting machine to the tractor is ensured by the three-point suspension system located on the tractor. The pneumatic safflower harvesting machine is of the suspended type, and its connection to the tractor is provided by the three-point suspension system. The chassis (19), which carries all the parts forming the machine, is made of U-profile and, in parking position, ensures the stability of the machine by means of four hinged legs.

[0064] The invention provides significant convenience in safflower varieties with both thornless and thorny forms, eliminating the difficulty, labour and tediousness of harvesting.

[0065] With the invention, the safflower flowers are collected solely by means of negative air flow. The work efficiency is considerably higher compared with other systems. Due to the thorny structure of safflower, people are not affected and do not suffer harm. Within the limited time available for collecting safflower flowers, the invention enables rapid harvesting with high efficiency. Therefore, the invention both increases quality and reduces flower losses. Since the motion transmission in the invention is carried out by means of the hydraulic system (10), it does not depend on the power and / or size of the tractor and can be used with tractors of different sizes. During the harvesting of safflower flowers, only the flower part is harvested, while the head containing the seeds remains on the safflower plant. By means of the specially designed headers used in harvesting safflower flowers, the flowers can be collected easily and without damage. The harvesting headers (1 ) that collect the safflower flowers are in three parts and surround the plant from the top and from the sides.
