Precision and speed in the weighing process with possibilities of monitoring by worker, registration of tares by type of tubs or containers that is activated with the selection of the operator, etc. Greater precision in weight means a very important saving, since at present the traditional system is weighed upwards to avoid suffering penalties and with greater precision a saving of 50 to 6% by weight of the product can be achieved.

2. Reduce the time spent collecting.

3. Reduce the cost of labor required.

4. Less deterioration of the fruit by reducing the times it is handled.

5. The carts object of the present invention are stacked on top of each other, reducing the storage space requirements by more than seventy percent in the period in which the collection is not carried out, approximately eight months per year. . 5

6. Very small weight of the set and easy to handle.

EXPLANATION OF THE INVENTION

By way of explanation of the “Hand truck adapted for the collection and weighing in electronic scale 10 of berries” it is a manual work equipment designed to be easily stackable, consisting of a main structure based on a shaped metal tube that delimits a main loading tray destined to contain on one side the load cell of the electronic balance in which the box or packaging that will contain the fruit will be located and, in front of it another area where another box could be located to go 15 depositing in it the fruit in poor condition or as an empty box available to use once the one in the balance is filled, extended down to accommodate a solid wheel and on two parking legs, while upwards it has a extension in the form of a handle on the opposite side to which the wheel is located, while on the wheel a backrest on which the screen d is housed is extended upwards e 20 display and control of the balance.

Thus, the electronic balance in order to avoid the inconveniences of weighing a load that is in motion, on a surface that is not always horizontal or uniform, has been conceived provided with a rubber casing of non-slip material that prevents the displacement of the boxes when placed on it and so that it presents a weight on the balance monitor that is the result of calculating the average between the weight collected at each of the four ends, where in addition each of these four scales does not take into account the first measures associated with the displacement of the extensiometric cells as a result of the movement of the assembly substantially increasing the accuracy of the measurement.

The set is complemented by a front ring fixed to the aforementioned backrest on which the display and control screen of the balance is located aimed at containing a bucket designed to deposit garbage such as butts, papers, plastics or even the own harvested fruit that does not exceed the minimum quality standards.

While the handle also contains a metal cube designed to contain a notebook, pens or labels to be used during the time of collection.

 40

Thus, from the “Hand car adapted for the collection and weighing in electronic berry scales” described and once the initial parameter adjustment has been made by the promoter, the use thereof consists in selecting the application program that determine the format of the container, applicable tolerance and tare, place a tray with the corresponding empty tubs on the balance, carry out the collection of the fruits 45 filling one by one each of the tubs until indicated by the light or acoustic signal For this purpose, at which time the next tub will be filled and, once all the tubs have been completed, the referred car is approached to the area where the full trays are deposited, removing the tray and relocating another empty tray to continue with the collection. fifty

Once the car described has already been used and can be stored until the following season, to reduce the storage space needs you can remove the wheel from your fork and store the cars one on top of the other as stacked chairs.
