Abstract

Electric harvesting cart with five wheels for harvesting and transporting fruit and vegetable products from greenhouses. It consists of a chassis supported by four rotating wheels and a central one that acts as a pivot and provides traction to the cart by connecting an electric motor to it. The machine controls are placed on two handles at the ends where all the controls for moving the cart are located. The platform where the boxes are transported is extendable to adapt to the box required for each production, and these, when not in use, can be stored empty on a removable shelf located at the top so that they do not get in the way while the harvesting tasks are carried out.

Description

DESCRIPTION

Five-wheel electric harvester cart

The present invention relates to a five-wheeled electric traction cart for harvesting agricultural products. The cart moves on four rotating wheels and a central one to which an electric motor is connected to facilitate its movement. It rotates 360° with the rotation point at the central wheel. This central wheel provides greater maneuverability. It has a handle on both sides of the machine from where it is steered, and where all the machine's maneuvering mechanisms are installed, with a trigger accelerator to move it, a lever to select the direction of travel, the power switch and an emergency button. It has a removable structure on the top to store empty boxes before harvesting the product if required.

Technical sector

This invention has its application within the industry dedicated to the manufacture of equipment, devices and elements applicable in agriculture in general and harvesting machinery in particular.

Background of the invention

Carts have long been used for harvesting and transporting crops to facilitate these tasks, as they are easy to transport and manage. For difficult terrain and when loaded, these facilities become more complicated and the operator needs to make a great effort to move the carts.

The five-wheel electric collection cart solves these problems of operator effort by allowing the cart to be moved electrically, simply by pressing a trigger accelerator, and collecting a greater number of boxes of product at a time, in addition to giving the cart great stability due to the action of the central wheel.

Explanation of the invention

The five-wheel electric harvesting cart is a novelty in its field of application, solving the above-mentioned problems. Operators need to make less effort and therefore work is more efficient and less tedious, being able to transport heavy loads with little effort.

More specifically, the electric collection cart is made up of a metal chassis that gives the whole unit robustness, all covered with a protective anti-corrosion paint.

The chassis is supported by four swivel wheels at its ends and a central fixed wheel to which an electric motor is connected to help traction of the cart. The fact that the four outer wheels are swivel helps to make turns and maneuver more comfortably through the aisles of the crop fields, and the central wheel acts as a pivot for turning the machine, and prevents the machine from moving involuntarily. In addition, the two rear wheels have a certain vertical freedom with respect to the central wheel that allows it to copy the terrain it passes through, making it very difficult for one of the wheels to become airborne, and therefore, having greater stability.

It has a handle on both sides of the machine, where the entire control system is located, including a trigger accelerator, the ignition switch, the direction selector lever and an emergency button. Batteries are responsible for providing power to the machine's electrical system.

The boxes will be supported on a platform which has two extendable structures that allow boxes of various sizes to be placed simply by extending said structures.

The chassis supports a removable upper structure designed to store empty boxes for later collection of the product and tools that help operators with this task.Brief description of the drawings

Preferred embodiment of the invention

The electric harvesting cart with five wheels is made up of a metal chassis (1), coated with an anti-corrosion protective paint and dimensionally adaptable to the crop to be treated. The chassis (1) is supported by four rotating wheels (2) at the ends and a fixed central wheel (3) connected to an electric motor (4) that provides traction to the cart. It also has a platform (5) where the boxes are supported for the collection of the product, with two extendable structures (6) to adapt to the size of the box. At the ends, on two handles, the control knob (7) is located, where all the electric actuators are installed, the ignition switch, the lever to select the direction of travel, the trigger accelerator and the emergency button. The electrical system is powered by batteries (8) placed under the harvesting platform (5). On this platform (5) a removable upper shelf (9) is assembled, intended for the placement of the empty harvesting boxes for later use and the work tools.

Two of the rear swivel wheels (2) are connected to the central wheel (3) by a rocking mechanism that ensures that all the wheels are always supported on the ground, even if it is not uniform, thus increasing stability. The central wheel (3) acts as a pivot for the cart's rotation and the swivel wheels (2) accompany it.

Claims (2)

1. Five-wheel electric harvesting cart for transporting and harvesting fruit and vegetable products in greenhouses, consisting of a metal chassis (1), coated with anti-corrosion protective paint. Supported by four rotating wheels (2) arranged at the ends of the machine, and a fixed central wheel (3). A work platform (5) on the chassis (1) with two extendable structures (6) on the sides. At the ends, on two handles, the control knobs (7) of the cart are located, and in this the electric actuators, ignition switch, lever to select the direction of travel, emergency button and trigger accelerators. The central wheel (3) engages with an electric motor (4) and this is powered, as are the control knobs (7) with batteries (8) located under the platform (5). On said platform (5) a removable upper shelf (9) is placed. 2. Five-wheel electric harvesting cart according to claim 1, characterized in that two of the rotating wheels (2), the rear ones, are connected to the central wheel through a rocker mechanism that copies the ground.
