Description

Oil palm ear harvesting tool

technical field

The utility model belongs to the field of plant fruit harvesting, and relates to an oil palm ear harvesting device, in particular to a tool for oil palm ear harvesting.

Background technique

Oil palm (Elaeis guineensis Jacg.), is an evergreen tall tree (about 8-20 meters high) of the palm family (Palmae) oil palm (Elaeis). Oil palm ears grow in the leaf axils, and the weight of a single ear is 5-20 kg or more. The ear harvesting method is to insert a knife into the leaf axil to cut off the fruit stalk and take out the ear. When the included angle of the blade is small, the blade is cut off at the base of the blade earlier, and then the harvesting knife is inserted into the gap between the trunk and the base of the handle of the ear to cut off the handle and take out the ear. In terms of production, when the height of the tree is high, a sickle-shaped harvesting knife is used: the knife body is curved, and the width of the knife tip and the knife body is basically the same. The actual usage shows that this kind of knife is more suitable for ear harvesting with larger angles between the base of the blade and the base of the ear (leaf/fruit), and the base of the ear and the trunk (fruit/trunk). The knife body is too large, and it is difficult for the harvesting knife to penetrate into the gap. The harvesting is very time-consuming and laborious, and the oil palm ear harvesting fee increases and the efficiency is low.

Utility model content

The purpose of this utility model is to provide a kind of oil palm ear harvesting tool for different types of leaf/fruit and fruit/dry angles for the deficiencies of the prior art, which is more suitable for different types of leaf/fruit and fruit/dry angles. Harvesting ears with dry angles can reduce harvesting intensity and improve harvesting efficiency.

The technical scheme adopted in the utility model:

A knife for harvesting oil palm fruit ears, which is composed of a knife tip, a knife body and a knife handle. The knife tip is in the shape of a sharp triangle, and the angle between the knife edge and the knife back is 5 degrees; Curved, the two ends of the knife body are respectively connected with the knife tip and the knife handle. Thus, the harvesting cutter is constituted by a sharp triangle tip, a curved blade body and a handle of a knife. When harvesting fruit ears, insert the sharp triangular knife tip into the gap, which can cut off the base of the leaves or the fruit stalk relatively smoothly.

The blade back hypotenuse length of the blade tip is greater than the blade body arc length.

The utility model has the advantages of simple structure, low cost, and convenient use. It adopts a sharp triangular knife point and a curved knife body structure, which can realize fast harvesting of fruit ears with different angles from the base of the leaves, and has high harvesting efficiency and labor-intensive harvesting. Low, suitable for popularization and application in the field, and can be used as one of the tools for oil palm ear harvesting.

Description of drawings

Fig. 1 is a schematic cross-sectional structure diagram of the utility model.

In the figure: 1, the tip of the knife; 2, the body of the knife; 3, the handle of the knife; 4, the edge of the knife.

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 harvesting tool designed by the utility model is made of tip 1, blade body 2 and knife handle 3, and the included angle of described tip part is a sharp triangle, and tip The length of the hypotenuse on the back of the knife is 28 cm, and the tip of the knife is connected with the blade body 2; connect. When harvesting oil palm trees with different angles at the base of the ear leaves, the knife tip 1 with a sharp triangular structure at the front can easily enter the base of the ear leaves, and then use the curved blade 2 to cut the base of the leaves and the handle of the ear to complete 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.

Claims (2)

1. a kind of oil palm ear harvesting cutter, it is characterized in that: be made of tip of a knife, blade body and handle of a knife, described tip of a knife is a sharp triangle, and the angle between blade and back of a knife is 5 degrees; Described blade body is curved The structure, the blade is ballistic curve, and the two ends of the blade are respectively connected with the tip and the handle. 2. The cutter for harvesting oil palm fruit ears according to claim 1, characterized in that: the length of the hypotenuse of the knife back of the knife point is greater than the arc length of the knife body.
