Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for treating lower leaves of leafy vegetables such as spinach, komatsuna, and spring chrysanthemum. More specifically, the present invention relates to a method for automatically removing muddy soil and unnecessary lower leaves from leafy vegetables harvested from a field. It relates to technologies that can be removed.

[0002]

2. Description of the Related Art As this kind of lower leaf processing apparatus, there is known a lower leaf processing apparatus disclosed in Japanese Patent Application Laid-Open No. Hei 10-262634, in which spinach is transported by a plurality of transport belts in a lying position. Meanwhile, the lower lobe removing mechanism is configured so that the lower lobe is rolled up and removed by the large-diameter roll and the small-diameter roll.

[0003]

In the lower leaf processing apparatus according to the above-mentioned prior art, the specifications of the publication are described in the specification on page 5, right column, Nos. 6-13.
As described in the row, the first transport belt (reference numeral 4a) for placing and transporting the spinach in the lying position and the fourth transport belt (reference numeral 23) for applying the transport force while pressing the spinach from above. The distance between the lower leaf removing mechanism (reference numeral 10a) and its driving unit (reference numeral 24) can be adjusted in the distance movement direction so as to be able to cope with a change in the length of spinach.

However, in the above structure, the moving part is a part having a relatively complicated structure, and is large and heavy, so that the interval adjusting mechanism becomes large, and it is presumed that the adjusting operation is not easy. So there seems to be room for improvement in that regard. SUMMARY OF THE INVENTION An object of the present invention is to realize an adjusting structure for obtaining a transporting and lower leaf removing function corresponding to the length of leafy vegetables, with a simpler structure and a lower price than before.

[0005]

Means for Solving the Problems [0014] In a first aspect of the present invention, in a lower leaf processing apparatus for leafy vegetables, a transport belt for loading and transporting leafy vegetables harvested from a field in a reclined position, A lower-leaf processing mechanism that scrapes and removes the lower leaves of leafy vegetables conveyed by the belt with a rotating rotating body and removes them from the base of the leaf, and a conveyor belt that presses the leafy vegetables conveyed by the conveyor belt from above And a presser belt that applies a conveying force in the same direction as the leaf vegetable transport direction by the lower leaf processing mechanism over a range where the leaf vegetable is processed. The position is adjustable.

A second invention is characterized in that, in the first invention, the presser belt is configured to be able to retreat upward from an operation posture in which the presser belt presses the leafy vegetables and imparts a conveying force to the leafy vegetables.

According to the first aspect of the present invention, the pressing belt is configured to be capable of adjusting the position of the pressing belt in the distance direction with respect to the lower leaf processing mechanism, thereby coping with a change in the length of leafy vegetables. In other words, the distance between the transport belt and the lower leaf processing mechanism is not changed, and only the position of the presser belt is moved in the near and far directions, so that the position of sandwiching the leafy vegetables by the transport belt and the presser belt is adjusted in the stem direction of the leafy vegetables. Is what you do.

[0008] Since the pulling force generated by the stripping action of the lower leaf processing mechanism by scraping the lower leaf is opposed to the leaf vegetable pressing position by the pressing belt and the transport belt, only the position of the pressing belt is adjusted. The pressing position can be changed according to the length of the leafy vegetables, and the transport belt does not need to be moved. Therefore, since it is only necessary to provide a position adjusting structure for only the presser belt, the size, weight, structure, and the like of the portion to be moved can be simplified as compared with the related art.

According to the above-mentioned publication, if the length of leafy vegetables is long, the amount of protrusion from the conveyor belt becomes large, and the root side of the stock is drooped too much to be transferred to the lower leaf processing mechanism. When the length is short, there is a risk that the amount of protrusion from the conveyor belt is small and a sufficient lower leaf scraping action is not provided on the stock base side. Is fixed, so that the length of protrusion from the conveyor belt at the base of the stock can be constant regardless of the length of the leafy vegetables, making the base of the stock ideal for stripping the lower leaves. This is convenient in that it can be easily transferred to the lower leaf processing mechanism in the state.

According to the second aspect of the present invention, the pressing belt can be retracted upward from the action posture for pressing the leafy vegetables and imparting a conveying force to the leafy vegetables. When the leaf vegetables are clogged near the input port, the release operation, maintenance, cleaning, and the like can be easily performed.

According to the first and second aspects of the present invention, the distance between the transport mechanism and the lower leaf processing mechanism is substantially reduced by changing the idea of adjusting the position of only the presser belt. Thus, a configuration in which the lower leaves can be satisfactorily removed even when the lengths of the leafy vegetables are different can be realized at a low cost with a simple structure and position adjusting operation.

In the lower leaf processing apparatus according to the second aspect of the present invention, the holding belt can be retracted upward so that clogging can be easily cleared, and cleaning and inspection can be easily performed.
