Description

The present invention relates to an agricultural equipment for soil seeding. Field of the invention The invention is in the technical field of agricultural equipment and apparatus, in particular in the technical field of pressurised seed drills. Prior art In the agricultural field, there are numerous types of agricultural equipment that are used according to the requirements, needs and purposes for which they are intended. A particular type of agricultural equipment comprises all those devices that perform the function of a seed drill. Over the years, numerous types of seed drills have appeared on the market in order to meet the needs of the sector and users. Traditional seed drills used in agriculture for seed distribution are designed to ensure precise and uniform distribution of seeds and/or fertiliser on the ground. Among these, pressurised seed drills have proven effective in improving sowing precision and speed, while reducing product waste. The general principle of functioning of a pressurised seed drill involves a system consisting of a fan that generates an air flow in the main line and in the pressure induction pipe that communicates with the hopper. When the pressure in the main line and the hopper is equal, the dosed material flows freely from the storage hopper to the main transport line. Subsequently, the dosed material (seeds and/or fertiliser) reaches the dosing systems and is spread on the ground. In particular, in pressurised seed drills, a system of pipes connects the hopper environment with the pipes or hoses, where the metering system pours the seeds, so that the two environments are isobaric. Preferably, the connecting pipe between the two environments is inserted into the metering device of the agricultural equipment closest to the fan. Pressurised hoppers are currently available on the market, which are particularly suitable for this type of seed drill, equipped with a single compartment or, in some cases, with two, three or four compartments. However, the number of compartments inside the hoppers remains fixed and cannot be changed by the user who has purchased the agricultural equipment. To overcome this limitation, a number of solutions have been adopted that involve the addition of an external tank to create an extra compartment to add to those inside the hopper. However, these solutions have the following disadvantages: the additional external tank is mounted outside the hopper and increases its overall size;the additional external tank requires dedicated and complex motor and electronics management, which increases overall complexity and costs;the additional external tank causes a shift in the centre of gravity of the base equipment. An example of this solution can be seen in figure 8 and is indicated by the reference number 200. In said figure, an additional tank 201 can be seen, which must be mounted externally to the agricultural equipment and requires dedicated electronic and pneumatic instrumentation. The relevant prior art also comprises patent applications US5592889A, DE102016121559A1, GB2346308A, US2004/026544A1 and DE102009025761A, which generally describe solutions having three native internal compartments with associated dosing devices. Aim of the invention The aim of the present invention is therefore to provide agricultural equipment for soil seeding that is capable of resolving the aforementioned drawbacks and critical issues. Another aim of the present invention is to create agricultural equipment for soil seeding that improves on similar agricultural equipment currently available on the market. A further aim of the present invention is to provide agricultural equipment for soil seeding, such as a pressurised seed drill, that can contain and sow more than two products. Another aim of the present invention is to create agricultural equipment for soil seeding that can be integrated with existing agricultural equipment, such as pressurised seeders. A further aim of the present invention is to provide agricultural equipment for soil seeding, such as a pressurised seeder, that does not require external tanks. Another aim of the present invention is to provide agricultural equipment for soil seeding, such as a pressurised seed drill, which has a hopper capable of holding three different products. These and other aims are achieved by agricultural equipment for soil seeding according to the attached independent claim. Further detailed technical features are set out in the attached dependent claims. Brief description of the figures The present invention will now be described, by way of example but not limitation, according to some of its preferred embodiments, and with the aid of the attached figures, in which: figure 1 is a perspective view of the agricultural equipment for soil seeding according to the invention;figures 2A and 2B are two perspective views of a section of the agricultural equipment for soil seeding according to the invention, in two different embodiments
