Description

A single-edged harvesting knife for oil palm ears

technical field

The utility model belongs to the field of plant fruit harvesting, and relates to a harvesting knife, in particular to a single-edged harvesting knife for oil palm ears.

Background technique

Oil palm (Elaeis guineensis Jacg.) is an evergreen tall tree (about 8-20 meters high) of the genus Elaeis in the palm family (Palmae). Oil palm ears grow in the leaf axils, and the weight of a single ear is 5-20 kg or more.

At present, there are two methods for harvesting oil palm fruit ears: one is when the tree body is high, use a "curved" harvesting knife to reach into the leaf axil to cut off the fruit stalk and take out the fruit ears; the other is when the tree body is low , Use a "straight knife-shaped" harvesting knife to cut off the fruit stalk directly outside the leaf axil and take out the ear. In production, when the tree body is low, the harvesting knife used: the blade is straight, and the width of the blade is basically the same as that of the blade. The actual use situation shows that this knife is more suitable for the ear harvesting with larger gaps between the base of the oil palm leaf and the base of the ear (leaf/fruit), and the base of the ear and the trunk (fruit/dry). The width of the blade is the same, the side of the blade of the harvesting knife will hinder the operation, the harvesting is very time-consuming and laborious, the cost of oil palm ear harvesting increases and the efficiency is low.

Utility model content

The purpose of the utility model is to provide a single-edged oil palm ear harvesting knife for the deficiencies of the prior art, which is suitable for harvesting the ears of oil palm trees with a relatively low body, can reduce the harvesting intensity, and improve the harvesting work efficiency.

The technical scheme adopted in the utility model:

A single-edged harvesting knife for oil palm fruit ears, which is composed of a blade, a blade body and a handle. Isosceles trapezoidal structure, the upper and lower ends of which are connected with the handle and blade respectively, thus forming a harvesting knife. When harvesting fruit ears, holding the handle of the knife can directly use the blade at the front to cut off the leaves or the base of the handle .

The blade body and the handle are a streamlined structure.

The utility model has the advantages of simple structure, low cost, and convenient use. It adopts an equilateral triangle blade and an equilateral trapezoidal blade body structure. The harvesting labor intensity is low, it is suitable for popularization and application in the field, and can be used as one of the oil palm ear harvesting tools.

Description of drawings

Fig. 1 is a structural representation of the utility model.

In the figure: 1, blade; 2, blade body; 3, handle.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and examples, but not as a limitation of the utility model.

In the structure shown in Fig. 1, a kind of oil palm fringe single-edged type harvesting knife designed by the utility model is made of blade 1, blade body 2 and knife handle 3, and described blade is straight-line structure, and length is 10 cm, and its cross section is an equilateral triangle structure; the blade body 2 is an isosceles trapezoidal structure, the length of the trapezoidal hypotenuse is 18 cm, and the width of the lower end is 10 cm, connected with the blade 1, and the width of the upper end is 8 cm, connected with the handle 3 Connection, the blade body 2 and the handle 3 are a streamlined structure. When harvesting the ear leaves with a lower body, the blade 1 at the front end can be used to conveniently cut off the petiole and the ear handle at the base of the ear leaves to complete the harvest.

The above is only the preferred embodiment of the utility model, and it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the utility model, some improvements and modifications can also be made. And retouching should also be regarded as the protection scope of the present utility model.
