Description

DESCRIPTION

Electric traction trolley for rail

The present invention refers to a trolley with electric traction for the collection of fruits and vegetables for greenhouses heated by rail tube. This trolley moves through the rails on two axes, one of them with electric traction that makes the movement easier for users. Due to the layout of the control panel and the implementation of a work platform, the operator can work on the trolley, or from the ground as appropriate. It also incorporates a self-guiding option, with a proximity sensor, so that the carriage moves as the operator advances.

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 products grown in greenhouses to facilitate such tasks. Since the use of rail tube heating was implemented in greenhouses, the use of conventional trolleys was affected by their difficult access by the cultivation lines. Then came the collection carts with roller shafts that rest on heated rails. But there is a downside for the workers when the carts are loaded. Due to their weight, their mobility costs.

The electric traction trolley for rail allows the operator to transport the product without physical effort, even with the trolley fully loaded.

In addition, another drawback of conventional carriages is in the movement through the lines. When a worker has to be handling the crop and at the same time pushing the cart, time is wasted between stopping manual work and moving. With the implementation of proximity sensors, the operator will be able to operate on the crops from the ground and, when walking, the cart will move on its own, making sure that the time of pushing the cart is not lost.

Explanation of the invention

The rail traction carriage constitutes in itself a novelty within its field of application, solving the aforementioned problem. Efficiency is greatly increased because operators do not tire when carrying heavy loads. And with the proximity sensors of the operator, the times between the manipulation of the crop and the push of the cart to harvest another area of the line are lost.

More specifically, the electric traction trolley for rail is made up of a metal harvesting chassis that provides robustness to the set, whose dimensions are adapted to the different types of crops. Said chassis is covered by a protective anticorrosive paint.

It has two axles, counting the front one with electric traction, whose movement is provided by an electric motor geared through the motor pinion and another pinion welded to the shaft. Both front and rear axles have rollers that are supported directly on the heated rail tube of the greenhouse. But the front also has two wheels at its ends that allow it to advance when the car is not within the rails.

Two swivel wheels are also welded to the rear that allow the trolley to move laterally when it is on the ground.

The work platform, where the operator climbs, in turn acts as a drawer cover to house all the necessary electrical elements, such as batteries, charger or electrical box.

At the rear, a handle is placed to push the trolley manually. In front of it is placed another handle that also acts as the control panel of the traction carriage, where all the pushbuttons and operating levers are located.

A pedal is installed on the work platform for linear movement of the carriage when the operator is on it.

In addition, proximity sensors will be located on the trolley so that, when the operator is detected, he or she accompanies him without the need to activate any button.

Preferred embodiment of the invention

The electric traction trolley for rail is composed of a metallic chassis (1), adaptable in dimensions according to the crop to be treated, covered with protective anticorrosive paint to prevent wear. Two axles are incorporated into this, a front traction axle (2), geared by an electric motor (16) that transfers the car, and another rear axle (3). Both the front axle (2) and the rear axle (3) have two rollers (4) that are supported directly on the heated rail tube of the greenhouses. Two wheels (5) are installed at the ends of the front axle (2) that act as tractors when the cart is on the ground.

Two rotating wheels (6) are located in the lower rear part of the trolley, which give the trolley directionality when it is on the ground. Both the front wheels (5) and the swivel wheels (6) are suspended when the trolley is on the greenhouse rails.

A drawer (15) houses all the necessary electrical elements of the traction carriage. In it are the batteries (8), the charger (9), the electrical box (10) and the electric motor (16). Making the lid of this drawer (15) a work platform (7) where the user operates. On this work platform (7) a pedal (14) is placed which, when depressed, activates the linear movement of the carriage.

At the rear, a handle (11) is placed to push the trolley manually. While in the front part another handle is used as a control panel (12) of the traction carriage, where all the push buttons and operating levers of the same are located.

A proximity sensor (13) is installed that detects the operator making the cart move at the same time as it is working in the greenhouse. This proximity sensor (13) will be optionally installed as required.

Additionally, it allows the installation of a scale (17) to facilitate the counting of the product during its collection.

Claims (3)

1. Electric traction trolley for rail designed to facilitate the collection and transport in greenhouses with tube heating, consisting of a metallic chassis (1), covered with protective anticorrosive paint, to which a front traction axle (2) is attached, which meshes with an electric motor (16), and another rear axle. Each shaft has two rollers (4) that rest on the greenhouse rails. Two wheels (5) are also installed on the front axle (2). Two swivel wheels (6) are placed on the chassis (1) in the lower rear part, and a drawer (15) in the upper front part. Inside the drawer (15) the batteries (8), the charger (9), the electric motor (16) and the electric box (10) are located. There is a rear handle (11) and a front handle that acts as a control panel (12), where all the push buttons and operating levers are placed. On the drawer (15) a work platform (7) is placed, and on this a pedal (14) with linear drive. 2. Electric traction trolley for rail according to claim 1, characterized in that a proximity sensor (13) is optionally installed at the front for the linear movement of the trolley according to the movement of the operator. 3. Electric traction trolley for rail according to claim 2, characterized in that it is prepared for the installation of a weighing scale (17).
