1 / 7 DISPOSITION APPLIED TO A GRAPE BUNCH HARVESTER WITH TRACTOR-MOUNTED TILT ADJUSTMENT Introduction

[0001] This utility model patent application refers to a novel "ARRANGEMENT APPLIED TO A GRAPE BUNCH HARVESTER WITH TRACTOR-MOUNTED INCLINATION ADJUSTMENT", which is low-cost for the producer, compact in size, allowing it to be embedded in the tractor that uses the PTO, benefiting agility in maneuvers when harvesting the grapes from the bunches, on terrains with any inclination, which, by the action of the discs, fall by gravity directly into collection baskets without loss of must (juice), reducing maintenance costs, without the use of hydraulic oil and with only one person at the time of harvesting. Field of application

[0002] The innovation is applied in mechanized viticulture, more specifically in vines trained on pergolas. Technical persuasion

[0003] It is known to experts in the field that mechanized grape harvesting has been used to speed up the process and reduce labor costs, mainly in trellis vineyards due to the availability of equipment, but also in pergola systems.

[0004] The harvest should be carried out when the fruit reaches the appropriate sugar and acid levels for processing, whether for juice or wine, but it can be influenced by weather conditions that may advance, delay, or restrict the time for harvesting. The harvest also competes for labor at the time of harvesting other fruits produced in the same region.

[0005] The lack of labor is one of the main problems faced by winegrowers in terms of crop productivity. Among the strategies to minimize this problem, the importance of agricultural mechanization stands out. Petition 870250059909, dated 07 / 14 / 2025, page 5 / 12 2 / 7

[0006] Since harvesting is the operation that demands about half of all the labor employed in the viticultural production system, the mechanization of this operation has been advocated worldwide as an alternative to reduce labor and annual production costs.

[0007] The equipment must not cause damage to the grapes due to vibration, impacting crop quality, or to plant parts, interfering with the lifespan of the vineyard.

[0008] In this context, new equipment technologies that can enable profitable and sustainable harvesting in the pergola system are welcome in the segment in question. State of the art

[0009] The current state of the art includes some patent documents concerning grape harvesters, such as document BR 202015003866-1 entitled “ADAPTATION IN GRAPE HARVESTER” - which incorporates a grape harvester with tilt adjustment comprising a grape harvesting trailer equipped with a double hydraulic system, more precisely the collection trailer consists of an axle with two wheels, topped by a base hopper, overlaid by another upper hopper equipped with a set of transverse rows of discs with radial rods, the collection trailer is equipped with a panel of hydraulic levers and an air blower, the upper hopper being supported by a tilting mechanism consisting of two hydraulic systems, each positioned in the center of the side of the upper hopper, the hydraulic lifting systems being able to operate independently, enabling them to tilt the upper hopper to either side,The hydraulic systems' connections to the hopper have articulations; characterized by the base hopper having, in the center, a helical conveyor for transporting the harvested grapes.

[0010] The equipment described in the document above is a wheeled trailer, which makes it slippery on wet ground and causes it to stamp on the ground, compromising its quality. It is also an extended piece of equipment, hindering its movement. Petition 870250059909, dated 07 / 14 / 2025, page 6 / 12 3 / 7 at harvest time and the auger conveyor for the berries causes loss of must (juice) and higher maintenance costs. Finally, it uses hydraulic oil which is environmentally unfriendly.

[0011] Document BR 202017018184-2 entitled “CONSTRUCTIVE ARRANGEMENT IN GRAPE GRAIN HARVESTER” - characterized by a rotating cylinder with double and flexible rods, which form the harvesting discs incorporated into a hopper / collection box; the harvester is hitched to the tractor by two lower hitches and one upper hitch, and has a metal shaft with a transverse hole at a special angle of 2 to 10°, which is inserted into the main shaft of the rotating cylinder equipped with bearings; it also has a tube coupled to the main tube of the collection box. An extension of the shaft allows the inclusion of more harvesting discs, composed of flexible and double rods.

[0012] The grape harvester in the document above, with the possibility of support on wheels, has three fixed points, without adjustments, two lower and one upper, for attachment to the tractor's three-point hitch. The points are fixed because the angle adjustment is made on the sides of the hopper. The construction of the invention is complex, as it includes an extension of the hopper, double vibratory discs, and eccentric shafts on the same. A power generator is used as a support for the equipment. A high-power turbine is used to separate the berries from the leaves and twigs.

[0013] Ultimately, transporting the berries by conveyor belt causes damage to them, compromising their quality.

[0014] Document BR 202019012206-0 U entitled “CONSTRUCTIVE ARRANGEMENT IN HARVESTER” - describes a compact grape harvester for trellis harvesting systems, in the field of agricultural equipment, more specifically it comprises a collecting hopper equipped with two rotating cylinders fitted with harvesting discs that have flexible vibrating rods, and composed of two through shafts with a thickness of 35 mm that rotate causing the discs and rods to vibrate, so the leaves and grains fall onto a conveyor belt that leads them to an innovative separating unit, being deposited in a hopper / bin. Petition 870250059909, dated 07 / 14 / 2025, page 7 / 12 4 / 7

[0015] The equipment in the document above is also of complex construction and uses angular adjustment on the sides of the bucket and tracks. Objectives of the invention
