[0001] DESCRIPTION
[0002] Multi delivery system of pulsed acoustic waves for the harvesting and packaging of olives and other fruits
[0003] The present invention relates to a multi delivery system of pulsed acoustic waves for the harvesting and packaging of olives and other fruits, without applying physical action to the tree, by using elastic acoustic waves of appropriate frequency and high power. The system achieves harvesting as well as storage of olives and other fruits with very high efficiency, aiming at the highest possible quality while simultaneously reducing collection costs and alternate bearing of trees.
[0004] The present industrial application refers to a flexible pneumatic system for the mass delivery of pulsed waves (air rarefactions and compressions) in at least two directions with the aim of creating resonance (identification of the system frequency with the natural frequency of the oils) resulting in the achievement of the maximum possible amplitude and the maximum possible energy leading to the safe harvesting of oil-producing olives and other fruits, mainly from large spherical or cup-shaped trees, which to this day constitutes a particularly demanding and hard job, as it requires sufficient resources in labor, it must be done quickly, efficiently and with care for each tree. At the same time and synergistically, the optional launch of superabsorbent microcrystals is also possible in cases where increased power is required for the separation of the fruits. Finally, the ergonomic design of the system provides a dual use, as in parallel with the harvest, the separation from the foliage and the continuous packaging of the fruits are carried out.
[0005] In Greece, as in other countries, the same harvesting methodologies are used, which are as follows:
[0006] A) Completely manual: Picking by hand and bucket or using manual combs. A technique particularly widespread in table varieties, so as not to injure the fruit.
[0007] B) With hand-held machines (wooden sticks, electric or gasoline-powered vibrating olive thrashing machines and combs), however, the injury that causes damage to the plant's buds is one of the causes of the drop in production the following year.C) With heavy thrashing or vibrating machines attached to tractors (vibrating trunk thrashing machines, with or without an umbrella). In the case of using vibrating machines, the producer should choose low-vibration machines, or adjust its intensity so as not to injure the trees and there are no large losses in leaves. It is recommended that harvesting with vibrating machines be done when the force of cutting the fruit is lower.
[0008] D) Fully mechanical: This requires high-density (SHD) olive harvesters. These harvesting machines consist of a high tunnel, a mobile cabin, a full-height collection system and trays - plates where the olives will fall. The machine passes over the tree and inside the tunnel the branches oscillate, so that the olives fall into the collection plates.
[0009] However, mechanical harvesting can only be applied in fields without slopes and obstacles, where the trees have a limited height and have been planted under specific standards, so that the machine can pass between the trees without a problem. This method of harvesting is more widespread, among others, in California, Australia and in areas of Spain.
[0010] Also, gasoline-powered olive harvesters pollute the environment and the fruits, resulting in the tracing of undesirable substances in the olive oil. These exhaust gases in combination with those from the use of pruning machines and the burning of branches during collection (dioxins, hydrocarbons, etc.) increase the pollution of fruits and olive oil. These practices should be avoided. The variety of olive tree, the construction materials, the weight of the machines and their cost are complementary criteria.
[0011] Finally, for the use of vibrators, it is advisable to observe the following conditions:
[0012] 1. The trees should be single-stemmed with a trunk height of at least one (1) meter.
[0013] 2. Remove low shoots below 1.5 meters to facilitate the fall of the fruits.
[0014] 3. The shape of the tree should preferably be monoconical or pyramidal.
[0015] 4. Select soils with a slight slope
[0016] 5. The distances between the rows should allow the movement of the vibrator.Accordingly, the harvesting of other fruits such as chestnuts, almonds, etc. can be done either by hand or with appropriate harvesting machines. In our country, it is done primarily by hand. This is of course time-consuming and expensive due to the large number of workers required, which is why mechanization of harvesting, at least on large farms, is essential. Of course, as already mentioned, mechanical harvesting also requires suitable soil (small slopes) and in most cultivated areas of our country, the soil has a steep slope, is difficult to access and the crops are not intensively grown.
[0017] Therefore, there is a need for a multi delivery system of pulsed acoustic waves that does not have equipment that is difficult or heavy to transport and contributes to reducing the cost of collection while at the same time increasing efficiency and maintaining good quality of the trees. The prior art US 2003 / 6,609,359B1, US 2006 / 7,069,713B2 and US 2016 / 9, 439, 354B2 also describe methods and systems that seek to solve the same technical problems as the present invention but present technical disadvantages. Specifically, they are disadvantageous in efficiency and constant power, requiring a combination of procedures since the collection of olives / fruits is an operation that follows the mechanical operation of harvesting, in contrast to the present invention which achieves this without applying physical action of the machine to the olive tree through vibration or impact.
[0018] The system described in the present invention constitutes a method, based on which the harvest is completed rapidly and instantaneously through multiple waves of varying pressure that are transmitted spherically in all directions. The produced compressions and rarefactions of the air molecules have kinetic energy suitable to vibrate each olive fruit and to cut it smoothly from the branch, avoiding all the negative consequences of traditional harvesting methods.
[0019] With the application of the present invention, the complete harvest of oils of different types and colors is achieved, since there is a possibility of adjusting the frequency of the pulsed acoustic waves that fall on the fruits in order to achieve their resonance and their selective harvesting by species. At the same time, the ergonomic design of the system alsoallows the separation of the olive from the foliage and its continuous packaging in suitable bags.
[0020] The invention focuses on an upgraded and fully ergonomic system, whose function consists of creating pulsed acoustic waves through the combination of compressed and high flow directed air supply and the pulse generation membrane that delivers, depending on the magnitude of the pressure, very high frequency longitudinal mechanical waves produced in the air. The ability to also manually / automatically adjust the flow rate that affects the frequency of the system allows finding the natural frequency values of different types and colors of oils and other fruits easily, quickly and effectively.
[0021] According to the present invention, the above-mentioned purposes, as well as many more which will be better understood hereinafter, are achieved by using a multi delivery system of pulsed acoustic waves for olive harvesting which includes a robust metal motorized structure which in its internal part includes special mechanisms for converting acoustic frequency currents into elastic waves of appropriate frequency and power which bring about the effective and immediate harvesting of the olive.

[0055] A multi delivery system of pulsed acoustic waves for olive harvesting and packaging, according to the present invention, presents many advantages.Its ergonomic construction and autonomy minimize labor costs, which are the largest costs of olive and other fruit harvesting (particularly useful in our days when labor is limited and expensive).
[0056] Its operating efficiency remains consistently high (depending on fruiting, i.e. whether there is a windbreak or not and depending on the difficulties of the soil and planting). It can also harvest fruit on all soils, even on slopes, but also at heights of up to 9 meters.
[0057] The production of pulse waves of appropriate frequency and power, makes the system capable of harvesting all varieties of olive trees without breaking the branches and shedding leaves, resulting in them bearing fruit the following year, otherwise the quality deteriorates while often the wounds on the trees are sources of entry for pathogens. The ability to also manually / automatically adjust the supply flow that affects the frequency of the system allows for finding the natural frequency values of different types and colors of oils easily, quickly and effectively
[0058] Another advantage of the multi delivery system of pulsed waves for olive harvesting and packaging is that it is easily adapted to all types of tractors, but also more generally to machines that work with hydraulic systems, such as “backhoes”-excavators, bobcats, lifts, etc.
[0059] It also operates with independent hydraulics (from the tractor or any machine used), resulting in easy management and greater reliability. It does not have any particular wear and tear and it is easy to find spare parts.
[0060] The system requires only two operators, who can be trained in a short period of time without requiring any special knowledge from them. Its construction cost and maintenance are low due to the simplicity of the parts it consists of and therefore it becomes accessible to everyone.
[0061] Finally, its optional ability to launch superabsorbent microcrystals in cases where increased power is required for the separation of the fruits, gives the system an additional advantage, since the microcrystals, after falling to the ground, provide a multitude of applications in agriculturewhere they are used to improve water retention in the soil, save water, reduce the frequency of irrigation and enhance plant growth.
[0062] The figures provided illustrate an example of the application of this specific inventive idea. The construction and use of the present invention will be better understood from the following description and with the aid of the accompanying figures, namely:

[0066] Figure 4 illustrates the complete three-dimensional development of the multi delivery system of pulsed acoustic waves for the harvesting and packaging of olives and other fruits, with the individual construction details.
[0067] Figure 5 shows in detail part of the drive system that includes the adjustable speed multiplier (4), the drive activation and control system(5) that includes the two (2) stepper drive wheels (6) and the power transmission timing belt (7), the geared drive system (8), the lobeshaped drive blower assembly (9), the double-walled T-type pneumatic duct with insulation (10), the three (3) flexible elastic air chambers for temporary storage of compressed air (11), the pneumatic adjustable stainless steel pulse wave distribution membrane (12), the speed adjustment reducer (13) of the pneumatic adjustable stainless steel pulse wave distribution membrane (12) and the speed adjustment reducer of the microcrystal management system (25).
[0068] A non-limiting application of the method and the system that implements it is described below with reference to the attached figures.
[0069] With the operation of the system, three functions are achieved which take place in parallel and simultaneously:
[0070] • Pneumatic collection of olives and other fruits
[0071] • Storage of olives and other fruits as well as separation of foliage • and optionally the launch of superabsorbent microcrystals in cases where increased power is required for the separation of the fruits.
[0072] The main metal construction unit (1) of the present invention is a compact system that rests on a support base (32), of which the choice of shape and the material of construction, offers the ideal combination of weight / strength, which favors the easy transport and suspension of the system in any transport vehicle. It can be manufactured in various dimensions (length, width and height), so that its capacity can be varied according to the requirements of each customer.
[0073] The system is designed for transport and autonomous operation with agricultural tractors and is adapted to the hydraulic arms of all types of tractors through the suspension-retention arm system (2) that it has in a very simple way without further mechanical adjustments, while its reduced weight and dimensions allow its use even with small tractors.
[0074] The operation of the system is achieved through the connection of the cardan-type drive shaft (3) that it has with the tractor's PTO drive shaft located at the rear of the agricultural tractor and can transmit the engine's power in the form of rotary motion.As shown in Figure 2, the cardan drive shaft (3) is connected to a suitable adjustable speed multiplier (4) to increase the power transmission to the system in parallel and simultaneously to:
[0075] • the drive activation and control system (5)
[0076] • the lobe-shaped drive blower assembly (9)
[0077] The goal is to produce the optimal amount of air flow at the desired rate.
[0078] Specifically, as shown in Figure 5, the drive activation and control system (5) includes: two (2) stepper drive wheels (6) and a power transmission timing belt (7) connected to a geared drive system (8). The timing belt (7) is essentially a rubber toothed belt that connects the stepper wheels (6) with the gear wheels of the drive system (8) in order to synchronize the movement and transfer it to the speed adjustment gears (13) and (25) and to the air valve drive system (18) of the squaresection foliage / air separation system (21).
[0079] The lobe-shaped drive blower assembly (9) is a self-contained system designed to advance the pneumatic olive and other fruit collection line at the beginning of the operation, while at the same time it sucks and pushes air from the suction function of the fruits that have fallen to the ground for storage, preceded by the cylindrical filter element (24) for air purification. Its operation is based on the volumetric rotating lobe blower, which receives motion from a suitable adjustable speed multiplier (4) and includes all the necessary accessories and the soundproof cabin that guarantee its uninterrupted and most silent operation. The blower assembly stands out due to its particularly compact design and extreme strength of the construction materials.
[0080] Once the lobe blower assembly (9) is put into operation, the produced air is forwarded to the double-walled T-type pneumatic duct with insulation (10), where it is then divided and directed for storage and compression in the three (3) flexible elastic air chambers for temporary storage of compressed air (11). These are cylindrical air chambers which are filled with air and are used to compress and propel the air at a coordinated rate to the pneumatic adjustable stainless steel pulse wave distribution membrane (12), which in turn distributes the pulse wave atthe desired rate and frequency to the double system of conical receivers of two-radial cross-section (15), through the pneumatic butterfly valve (14) for selecting the direction of the compressed air.
[0081] Specifically, through the speed adjustment reducer (13), the pneumatically adjustable stainless steel pulse wave distribution membrane (12) is activated in order to control the air flow. It is a cylindrical cross-section membrane, the design of which allows for high flow capacity and low pressure drop because it is relatively thin and has a large surface area that comes into contact with the fluid, which reduces turbulence and drag. The ability to also adjust and position the rotation angle to fully open or closed makes it fast and effective for controlling the flow of gas / acoustic waves.
[0082] The acoustic wave propagates by causing condensations (compression) and rarefaction (rarefaction) of the molecules of the propagation medium as a result of oscillations around their equilibrium position. The most important parameter affected is pressure. Thus, acoustic waves can be described in terms of changes in the pressure of the propagation medium which, due to the oscillation of the particles, undergoes local increases (compressions) and decreases (rarefactions). The possibility of a low pressure drop allowed by the pneumatically adjustable stainless steel pulse wave distribution membrane (12) leads to the maximum rounding movement of the mass point near its equilibrium position, resulting in resonance resulting in the maximization of the amplitude.
[0083] As is known from physics, each oscillator can oscillate in a frequency range. The instantaneous excitation of an oscillator is equivalent to the output of a certain amount of energy to the oscillation. This is the free oscillation which occurs at a frequency that is identical to the natural frequency of the oscillator. When the oscillation is forced, its frequency is the frequency of the exciter. When the frequency of the exciter is identical to the natural frequency of the oscillator, we have resonance. During resonance, the system has the maximum possible amplitude and the maximum possible energy. If there are no damping forces, then the amplitude of the oscillation becomes theoretically infinite. Thus, the oscillation can become so intense that the oscillator is destroyed. If the energy supply is greater, then there is a risk of destruction of theoscillator. This possibility is exploited by the system of the present invention, since through the connection of its subsystems it is possible to adjust the amplitude of the oscillation so that the continuous fall / cutting of the olive and other fruits from the tree occurs, regardless of size and species.
[0084] The possibility of also manually / automatically adjusting the flow rate that affects the frequency of the system allows finding the natural frequency values of different types and colors of oils and other fruits easily, quickly and effectively.
[0085] After the frequency of the oscillation of the acoustic wave is determined, it passes forcibly through the pneumatic butterfly valve (14) to select the direction of the compressed air towards the double system of conical receivers of two-radial cross-section (15) for the transformation of the high-pressure / low-frequency acoustic power into low-pressure / high-speed power in free space. The choice of shape, dimensions and the way of supporting it on the main metal structure unit (1), make the double system (15) an absolutely solid body that minimizes the production of new sub-frequency frequencies that lead to the final attenuation of the pulse waves, ensuring satisfactory performance.
[0086] Each conical receiver of the double system of conical receivers with a two radial cross-section (15) has flat opposite walls, creating an angle with the top of the neck of the conical receiver which corresponds to the dispersion angle in the corresponding plane. In this way, the dispersion angle is constant at any change in frequency.
[0087] In parallel with the pneumatic collection of olives and other fruits, the storage of olives and other fruits as well as the separation of foliage also takes place. Specifically, as shown in Figures 2 and 4, through flexible rubber air / foliage / olive fruit suction pipes (16), the suction of fallen fruits as well as foliage from the ground to the main system (1) is carried out. The sucked mixture moves through the semi-cylindrical transport ducts (17) and is introduced into two (2) air / foliage / olive fruit separation systems (air cyclones) (19) where the separation is carried out based on size and density. The largest in size and densitycomponents (olives and other fruits) are precipitated first. This process forms a sediment (olives and fruits) which, through an olive fruit discharge air valve (20), is led to storage in suitable bags, while at the same time the supernatant fraction within the air cyclone (the lighter parti cles-foliage etc.) is air-transported to the two (2) square-section foliage / air separation systems (21), within which are placed diagonally, a stainless steel filter element of rectangular cross-section with perforated mesh for the effective separation of foliage / air (22).
[0088] The leaves are removed in a controlled manner through the foliage outlet air valve etc. (23), the movement of which is controlled by the air valve drive system (18), which is a drive cross that, as illustrated in Figure 4, is controlled by the drive activation and control system (5) and the geared drive system (8).
[0089] The separated air, with the aim of being reused by the system through the pressurized air ducts (33), is safely, without causing damage and deposits due to the suspended contained particles, directed towards the two (2) cylindrical filter elements (24), which essentially constitute filter arrangements used for the separation and retention of suspended dust particles from the air. The cylindrical filter elements are of stainless steel construction, of the type of industrial air filters, with a relatively wide angle, which captures the largest airborne particles in diameter, such as dust, animal hair, etc.
[0090] As mentioned, in parallel and optionally with the collection and storage of olives and other fruits, an optional launch of superabsorbent microcrystals can also take place in cases where increased power is required for the separation of the fruits.
[0091] The superabsorbent microcrystals (hydrogels) are crosslinked macromolecules with a portion of hydrophilic groups. The crosslinking agent, a monomer with two or more double bonds, provides the structure of the polymer network by linking the long linear chains in the polymerization. When such a network comes into contact with water or an aqueous solution, it increases its volume by absorbing water and solutes. The ability to absorb and store large amounts of water and aqueous solution makes hydrogels unique materials for a variety of applications.Some of the main characteristics of superabsorbent microcrystals, in addition to their swelling property, are:
[0092] • they present excellent biocompatibility, which is due to their high water content and their physicochemical similarities
[0093] • they have a degree of flexibility similar to natural tissue
[0094] • they have enhanced mechanical performance and swelling properties
[0095] The above properties, combined with the occasional need for increased power for the separation of the fruits, make it possible to use superabsorbent microcrystals simultaneously with the provision of acoustic waves to achieve the desired result.
[0096] Specifically, as shown in Figure 5, the speed adjustment reducer of the microcrystal management system (25), which is controlled by the drive activation and control system (5) and the geared drive system (8), activates the movement of the drive shaft and the microcrystal screw conveyor (26).
[0097] In turn, the drive shaft and microcrystal screw conveyor (26) drives the drive gears (27) which activate the corresponding microcrystal supply air valve (28) of the two (2) microcrystal separation (air cyclone) and storage systems (30), which microcrystals are transported via the drive shaft and microcrystal screw conveyor (26) to the microcrystal transfer pipes (29) where they are combined with the compressed acoustic wave that emerges from the pneumatic adjustable stainless steel pulse wave distribution membrane (12), for ejection for the effective collection of olives and other fruits.
[0098] Finally, the separation (air cyclone) and storage system (30) is connected to microcrystal transfer pipes (31) for the continuous supply of the system with material. The control of the incoming flow can be done either mechanically or automatically through metering servo mechanisms.
