DESCRIPTION

Harvesting trolley with electric drive

The present invention relates to an electric traction cart for harvesting agricultural products. This cart moves through four wheels, two of them traction, by the action of an electric motor, and the other two rotating, facilitating its movement through the workspace. The motor is activated by the actuation of a trigger accelerator, thus regulating the advance of the carriage.

A scale can also be incorporated to weigh the products while it is being collected; a proximity sensor, so that the carriage advances at the same time as the operator, without the latter having to press the aforementioned trigger; and a connecting hitch for coupling pickup trucks without traction.

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

Trolleys have always been used to collect and transport the products grown in greenhouses that facilitate such tasks. These carts are easy to transport and very manageable in the harvesting work, but there is a drawback when transporting said carts when they are full, the operator has to make a great effort to move, more so if the ground is not compacted.

In addition, during harvesting, the operator has to stop harvesting while advancing through the cultivation lines to move the cart with him, which means lost efficiency and time.

The collection trolley with electric traction makes it possible to alleviate all these drawbacks, avoiding transport efforts on the operator and making the trolley move next to it, being able to advance in the lines without the need to manually transport the trolley.

Explanation of the invention

The collection trolley with electric traction constitutes in itself a novelty within its field of application, solving the aforementioned problems. Efficiency is greatly increased because operators do not get tired when carrying heavy loads, nor do they interrupt harvesting work if they carry the operator's proximity sensors.

More specifically, the electric harvesting trolley is made up of a metallic chassis that gives the unit robustness, the dimensions of which are adapted to the different types of crops. This chassis is covered by a protective anticorrosive paint.

It has four wheels, two wheels mounted on a rear axle to which the electric motor engages, through a pinion, providing it with traction. And two other front wheels each mounted on a rotating fork that allow greater ease of movement.

The chassis contains in the upper part, a plate, where they support the boxes that will later be used in the collection, and a frame, which holds said boxes; In the lower part, some metal guides where you can place drawers to store work utensils, a drawer where all the electrical elements (batteries, charger and electrical box) and the electric motor support will be located; in the front part, a handle where a trigger accelerator is coupled that gives the signal for the car to advance electrically; and in the rear, a hitch to be able to join other manual cars without traction to the electric trolley.

The trolley is prepared so that a scale can also be added, to weigh the products at the same time they are collected, and proximity sensors so that the trolley moves at the same time as the operator.

Preferred embodiment of the invention

The harvesting trolley with electric traction is composed of a metallic chassis (1), adaptable in dimensions according to the crop to be treated, covered by a protective anticorrosive puncture to prevent wear. This chassis (1) contains a frame (2) that holds the boxes that will be placed for harvesting, a plate (3) where said boxes will be supported, some guides (4), under the plate (3), for storage of drawers for work utensils, a drawer (5) to house all the electrical elements (batteries (6), charger (7), and electrical box (8)), and a support for the electric motor (9).

The trolley has four wheels (10), two of them mounted on a rear axle (11), and two front wheels each mounted on a rotating fork (13) which are coupled to the chassis (1).

The electric motor (9) engages through a pinion (12) to the rear axle (11), thus giving the carriage the necessary traction for movement.

The front part has a handle (14) to easily and ergonomically move the trolley around the work area, which in turn serves as a support for the trigger accelerator (15) that gives the advance signal to the electric motor (9).

The electrical box (8) contains all the elements and wiring necessary for the operation of the trolley.

At the rear of the chassis (1) a hook (16) will be located to be able to couple other manual trolleys without traction to the electric trolley to facilitate the transport of said manual trolleys.

Additionally, the chassis is prepared to be able to mount a scale (17) on top of the plate (3), to be able to weigh the boxes as it is being collected, and some proximity sensors (18), which detect the operator while moving forward and make the car moves at the same time this.

Claims (2)

1. Collection trolley with electric traction designed to facilitate the collection and transport in greenhouses, consisting of a metal chassis (1), covered with protective anticorrosive paint, which contains a frame (2) and a plate (3) on the upper part , which, in turn, under said plate (3), guides (4) are placed. The lower part of the chassis (1) contains a drawer (5), where the batteries (6), the charger (7) and the electrical box (8) are located. It includes four wheels (10), two of them mounted on a rear axle (11) and another two mounted each on a rotating fork (13). The electric motor (9) is located at the rear, which meshes by means of a pinion (12) with the rear axle (11). At the front of the carriage there is a handle (14) that acts as a support for the trigger accelerator (15) that gives the signal for advancement of the carriage. At the rear there is a hitch (16) for towing cars. 2. Collection trolley with electric traction according to claim 1, characterized in that the trolley is prepared to place a scale (17) on top of the plate (3), and proximity sensors (18) at the front.
