Abstract

PURPOSE:To simultaneously carry out the housing of a tomato in a container and measuring thereof by constructing a measuring device installed under a charging table from a container table and a spring balance. CONSTITUTION:The tomato harvester is obtained by constructing a measuring device 61 installed under a charging table from a container table 63 attached through a linking mechanism 62 to a frame of a mobile machine body and a spring balance 65 hung through a supporting piece 64 from the frame. The weight of the tomato housed in a container 71 is measured by uncoiling the spring balance through a contact piece 66 attached to the lower end of the spring balance.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to tomato harvesters.
In recent years, there has been a strong demand for labor saving and efficient tomato harvesting work. The present invention relates to an improvement in a tomato harvester that meets such demands.

[0002]

2. Description of the Related Art Conventionally, as a tomato harvesting machine, a moving machine body, a hopper equipped on each of the moving machine bodies, a conveying device on the rear side of the hopper, a sorting table on the rear side of the conveying device, and the fruit sorting machine. A tomato harvester equipped with a loading device on the rear side of the stand has been proposed (Japanese Patent Publication No. 55-18485). This conventional machine puts the tomatoes that have been separated from the stems and leaves in advance into a hopper, and conveys the tomatoes from the hopper to a fruit-picking table by a conveying device.
After removing non-standard items such as stem and leaf fragments and earth and sand mixed in the sorting table and unripe fruits and rotten fruits, only excellent tomatoes are temporarily stored in the loading device. When the loading device is full of tomatoes, the loading device is tilted to store the tomatoes in the container installed in the lower field.

However, the above conventional machines have 1)
The tomatoes when they are fully loaded in the loading device are stored in the container. Therefore, the total weight of the stored tomatoes is affected by the shape and size of the tomatoes, and the total weight of the tomatoes actually stored in the container is higher than the standard weight. Since it is extremely heavy or light, it is necessary to re-weigh the total weight of the tomatoes after they are stored, and remove the tomatoes from the container or add them to the container. 2) Tomatoes are stored in the container. There is a drawback that the mobile body sometimes has to be stopped.

[0004]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is to remove the tomato from the container by reweighing the total weight of the tomato after accommodating it in the container from the loading device. Is a troublesome work to add to the container, and the mobile device must be stopped when the tomatoes are stored in the container.

[0005]

SUMMARY OF THE INVENTION The present invention, however, is directed to a mobile body, a front hopper equipped on the mobile body, a transport device on the rear side of the hopper, and a rear selection on the transport device. In a tomato harvester equipped with a fruit stand and an input table on the rearmost side, the fruit selection table is equipped with at least a reverse belt conveyor, and a weighing device is equipped below the input table, and the weighing device is A container stand attached to the frame of the mobile body via a link mechanism, a spring scale suspended from the frame via a support piece, and abutting against the container stand attached to the lower end of the spring scale. The present invention relates to a tomato harvesting machine, which is characterized in that

The tomato harvesting machine according to the present invention comprises a moving machine body, and a hopper, a conveying device, a selection table and a loading table which are sequentially mounted on a frame of the moving machine body from the front side to the rear side. ing. The mutual relationship among them is almost the same as that of the above-described conventional machine. Further, the tomato harvester according to the present invention is equipped with a weighing device below the loading table, and the weighing device is supported by the container platform attached to the frame of the mobile body via the link mechanism and the frame. It is composed of a spring balance suspended via a piece, and a contact piece attached to the lower end of the spring balance and abutting on the container table.

[0007]

[Operation] Tomatoes separated from stems and leaves are put into a hopper. The tomatoes loaded into the hopper are lifted by the transfer device and transferred to the sorting table. The tomatoes conveyed to the fruit sorting table have the non-standardized products such as unripe fruits and rotten fruits, in which the fragments of stems and leaves mixed with the reverse belt conveyor and contaminants such as soil are removed in the fruit sorting table. After being removed, it rolls to the loading table by its own weight, and is stored in the container placed on the container table of the weighing device installed below the loading table. As the tomatoes are stored in the container, the weight of the tomatoes causes the container base to swing down in the frame direction of the mobile unit via the link mechanism, and the spring scale is stretched via the contact piece to the container base. The weight at that time can be measured. When the value measured by the spring scale reaches the standard value, stop storing tomatoes in the container from the input table.

As will be described later, the weighing device is provided with an alarm device on a frame of a mobile body to which a link mechanism is attached,
Preferably, install a switch box linked to the buzzer,
It is advantageous to extend a limit switch from the switch box and attach a pressing tool for the limit switch to a movable piece forming the link mechanism. The container base turns down while turning in the frame direction of the mobile body, and the pressing tool also turns down, and when the container base moves down to a predetermined position, the pressing tool presses the limit switch to give an alarm. This is because the container placed on the container table is informed that the standard weight of tomatoes has been stored. Further, as will be described later, it is advantageous to open an input port on the input table and attach an opening / closing lid that can be restored by a spring to the input port. This is because opening and closing of tomatoes can be controlled by a simple operation from the loading platform to the container.

Therefore, according to the present invention, since the tomatoes can be accommodated and weighed in the container at the same time, after the tomatoes are accommodated in the container, the weight of the tomatoes is re-weighed and the tomatoes are removed from the container or added to the container. It is possible to save the troublesome work. Further, according to the present invention, since the container is placed on the container stand attached to the frame of the mobile body, the tomato can be stored in the container while the mobile body is running.
