Description

1 / 4 MULTIFUNCTIONAL MOTORIZED CART TECHNICAL FIELD

[01] This invention patent describes a multifunctional motorized cart equipped with a transmission system and a motor unit, which can be moved by human mechanical force or motorization, suitable for use in civil construction, rural activities, transportation of limestone and other minerals, and can function as a microtractor that, in addition to transporting products, implements and accessories, also transports its driver. BACKGROUND OF THE INVENTION

[02] Agricultural activities, especially on small and medium-sized farms, still rely heavily on manual labor rather than motorized equipment. These issues are related to the cost of equipment, which is often inaccessible to rural producers.

[03] The spreading of granular or powdered products is still carried out manually on small rural properties, including the transport of containers to the application site. Generally, the application is done by broadcasting, with repetitive movements that involve physical force.

[04] In these units, the diversity of operations and the restriction of resources demand multifunctional technical solutions. Equipment is generally used for moving products that requires human or animal traction.

[05] In this way, the Applicant developed a multifunctional motorized cart supported on a pair of axles, which provides compact and easily mobile equipment for field operations, bringing as its main advantage in relation to other vehicles and / or Petition 870250013205, dated 02 / 18 / 2025, page 5 / 19 Two or four agricultural machines are known in the state of the art for being lightweight, economical, and causing less environmental impact. The multifunctional motorized cart can be used to transport various products, extending to applications beyond just agriculture. BRIEF DESCRIPTION OF THE FIGURES

[011] The motorized multi-functional cart, object of the present invention, comprises a tubular chassis (10) equipped with tubes (11) and transverse beams (12) welded to the tubes (11), having a front axle (13) and a rear axle (14) on which pairs of wheels (20a) and (20b) are arranged, respectively.

[012] Optionally, a frame (14) is fixed in the center of the wheels and surrounds the sides and front portion of the tubular chassis (10).

[013] A main bucket (100) is positioned and fixed on the tubular chassis (10), which allows the transport of various products.

[014] The chassis (10) has at least one pair of external levers (101a) and at least one pair of internal levers (101b) that project from the rear portion of the chassis and at least one bar (102) that projects from the front portion, opposite the levers (101a) and (101b). Petition 870250013205, dated 02 / 18 / 2025, page 6 / 19 3 / 4

[015] In the motorized version, an engine (M) is positioned in a front support (30) on the chassis (10), said engine (M) preferably being 80cc or 100cc. The front support (30) allows the arrangement of the engine (M) and the fuel tank.

[016] A transmission mechanism includes a first chain (40) coupled to the pinion (not shown) of the motor (M) which transmits the movement of the motor (M) to the crown (50) of the axle and reduction shaft (13'). On the reduction shaft (13') is disposed a pinion (51), to which a second chain (41) is coupled which connects to the crown (60) of the front drive axle (13). In this way, the first chain (40) transmits the movement of the motor (M) to the reduction shaft (13') which, in turn, transmits reduced movement to the front drive axle (13). The front axle (13) transmits its movement to the front wheels (20a) for the movement of the cart. The movement of the front wheels drives the rear wheels (20b) and the rear axle (14).

[017] The inner levers (101b) have cables connected to the engine (M) for clutch and throttle movements.

[018] Optionally, angle bars (70) are provided welded to the base of the front support (30) and to the reduction shaft (13'), respectively, to prevent vibration and maintain stability in the tension of the chains (40) and (41).

[019] Optionally, secondary buckets (200) are arranged, fixed to the tubes (11) and crossbeams (12), below the main bucket (100), as shown in figure 5A. The secondary buckets (200) have a rotating cylinder (210) at their base, with a gear (220) at one end, to which a chain (230) is attached, fixed at the opposite end to a gear (141) fixed to the rear axle (14). The secondary buckets (200) Petition 870250013205, dated 02 / 18 / 2025, page 7 / 19 4 / 4 promote the distribution of limestone in the soil, with the main bucket (100) serving as a limestone reservoir to replenish the secondary buckets (200).

[020] Optionally, as shown in figure 5B, on the bar (102) that projects from the front portion, opposite the handles (101a) and (101b), at least one sprayer (300) powered by battery or motor is attached, with the hoses, rods and spray nozzles fixed in supports bolted to the tubular chassis (10).
