Description

[0001] DESCRIPTION

[0002] SIX-WHEEL COLLECTION CART WITH LIFTING STEP FOR ACCESS TO GOODS AT HEIGHT

[0003] TECHNICAL SECTOR

[0004] The present invention falls within the field of agriculture and is primarily intended to facilitate the cultivation and harvesting of produce in greenhouses. The objective of this invention is to simplify the work of farmers through an ingenious redesign of traditional harvesting carts, making them multifunctional so that this tool also facilitates access to elevated areas of the crop.

[0005] BACKGROUND OF THE INVENTION

[0006] Currently in the agricultural sector, specifically in the cultivation of vegetables and greens in greenhouses, there are a number of difficulties in carrying out the work efficiently during the cultivation and harvesting stage in areas that are difficult to access due to their elevation within the greenhouse itself.

[0007] While it is true that platforms currently exist to address this problem, there is no element that multifunctionally allows you to transport work objects or collection boxes while also allowing you to access elevated areas of the greenhouse.

[0008] EXPLANATION OF THE INVENTION

[0009] The inventor of this application has developed a new multifunctional work tool that ingeniously and effectively solves the problems described above. To achieve this, he has taken as his starting point the design of carts...

[0010] 1

[0011] REPLACEMENT SHEET (RULE 26) Traditional harvesting equipment used in greenhouses, which, as its name indicates, are work tools that allow the transport of harvested products without having to carry the weight of the boxes of produce during harvesting. Boxes containing the necessary objects or tools for carrying out different tasks during the care and cultivation phases of the crop can also be transported, thus avoiding carrying their weight.

[0012] In this case, the inventor aimed to maximize the functions of the harvesting cart to optimize and reduce the workload for farmers by adding a feature that allows workers to access the higher areas of their crops. The device's components will be described in more detail below, using numerical references that correspond to illustrative figures in Figure 1.

[0013] The traditional harvesting cart has been modified by adding a lifting step (6) at the rear with a base (5) on which its load is distributed, allowing workers to climb onto it and access higher areas. In addition, the rear push and pull handle has been replaced by two side handles (8) that also provide support for workers when climbing onto the lifting step (6). Because this update alters the cart's center of gravity, the relative position of the main axles (3) has been modified, and a secondary axle (7) has been added beneath the lifting step (6) to accommodate two wheels (9) smaller than the main axles (3). This provides the cart with complete stability when accessing the lifting step (6). These design updates to the traditional cart add two main advantages and functionalities over the original design.

[0014] On the one hand, during the harvesting phases, workers will no longer need to carry any additional equipment or tools besides the harvesting cart to access elevated areas. This represents a significant reduction in workload and costs, as the harvesting cart becomes multifunctional.

[0015] On the other hand, during the pruning phase, most farmers currently have to subsequently carry out cleaning and collection of the resulting debris.

[0016] 2

[0017] REPLACEMENT SHEET (RULE 26) With the invention presented in this application, the cart can be used to prune the elevated areas and at the same time transport boxes in which to dispose of the resulting plant remains, thus reducing and optimizing the work.

[0018] The latter is just one example of a use other than harvesting; there are also a number of other tasks that require a tool to access the upper areas of a greenhouse. All of these tasks can be performed with this invention, as it allows you to reach elevated areas and transport tools simultaneously.

[0019] BRIEF DESCRIPTION OF THE DRAWINGS

[0020] To complement the description being made and in order to help a better understanding of the characteristics of the invention, a set of drawings is included as an integral part of said description, in which, for illustrative and non-limiting purposes, the following has been represented:

[0025] PREFERRED EMBODIMENT OF THE INVENTION

[0026] By way of example, a practical implementation of the six-wheeled collection cart with a lifting step for accessing goods at height, which is the subject of this Utility Model, is shown. In order to facilitate the identification of the

[0027] 3

[0028] REPLACEMENT SHEET (RULE 26) Different parts that make up the invention device, each of them will be referred to with a number by which they can be identified in an illustrative manner in Figure 1. This invention device can be made by modifying some of the measurements cited below, according to the required needs.

[0029] For the implementation of this invention, it is preferable to start with the main platform (1), which will determine the device's capacity. Most traditional collection carts are designed to carry two standard-sized product collection boxes, so the design must be compatible with these dimensions without compromising its functionality.

[0030] The main base of the device (2) consists of two tubular structures, preferably 20-25 mm in diameter, with two curved sections and three straight sections. The arc and inclination of the main base (2) can vary depending on the dimensions of the main platform (1) and its desired height. Figure 2 illustrates the structural design of the device, showing the arrangement of its components to ensure proper use and operation.

[0031] The main axes (3) of the device are positioned to provide it with maximum stability. As shown in the provided drawings, the axes (3) are not symmetrically positioned, as the front axis has been moved away from the center to enhance the device's stability. Furthermore, a secondary axis (7) has been added at the rear to prevent the device from tipping over when a weight is placed on the lifting step (6).

[0032] The handle (4) on the front of the device is directly attached to the main base (2) from the height of the main platform (1), and preferably made up of one or more 25 mm diameter tubes, although it can always be of other similar dimensions.

[0033] The secondary base (5) is made up of a series of 20x20 mm rectangular bars distributed as follows:

[0034] REPLACEMENT SHEET (RULE 26) a) Four vertical bars. b) Two bars slightly inclined with respect to the horizontal plane that join the main rear axis (3) and the secondary axis (7). c) Two short horizontal bars that join the lifting step (6) with the main base (2). d) Two hollow bars that run the length of the lifting step (6) along its longer side and rest on the four vertical bars referred to in the first element described in this section of the secondary base (5).

[0035] The lifting step (6) rests on the secondary base (5) and is located at a height of 30 cm for this example, although this height can be modified as long as a possible correction of the position of the main axes (3) is taken into account to maintain the stability of the device.

[0036] The secondary axle (7) is located below the secondary base (5) to allow the placement of two wheels (9) at the rear of the device to provide greater stability.

[0037] The rear handles (8) are formed by cylindrical tubes with an arch at their highest point that are joined, on one side, to the rear ends of the main platform (1) and, on the other side, to the ends of the lifting step (6).

[0038] The wheels (9) used by the device can be of different types and sizes, although for this example, the wheels (9) on the main axles (3) are 350 mm in diameter and those on the secondary axle (7) are 260 mm in diameter. The recommended material for the frame is galvanized iron, although other materials can be used. Different types of wheels (9) can be used depending on the requirements, such as traditional pneumatic tires or puncture-proof tires.
