The utility model has the advantages of simple structure, low cost, and convenient use. It adopts a knife tip with a small angle and a curved knife body structure, which can realize rapid harvesting of the type of oil palm with a small angle (less than 20 degrees) at the base of the ear blade. The fruit ear of the tree has high harvesting efficiency and low harvesting work intensity, is suitable for popularization and application in the field, and can be used as one of tools for harvesting fruit ears of oil palm trees.

Description

A kind of tool for harvesting oil palm small-angle fruit ears

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 an oil palm small angle ear harvesting tool. the

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. Generally speaking, for the type with tough petiole base and small gap between the trunk and the ear stalk base, especially when the trunk is high, a sickle-shaped harvesting knife is used in production: the blade is curved, and the blade tip and blade Basically the same width. However, the actual usage shows that this kind of knife is more suitable for ear harvesting when the angle between the base of the leaf and the base of the ear (leaf/fruit), and the base of the ear and the trunk (fruit/trunk) is greater than 20 degrees. At the same time, because the tip of the knife and the body of the knife are too large, it is difficult for the harvesting knife to stretch into its cracks, so the harvesting is very time-consuming and laborious, and the oil palm ear adopts an increase in charges. the

Utility model content

The purpose of this utility model is to provide a kind of oil palm small-angle ear harvesting tool for the deficiencies of the prior art, which is more suitable for ear harvesting with leaf/fruit and fruit/dry angles less than 20 degrees, which can reduce the harvesting time. Harvesting strength, improve harvesting efficiency. the

The technical scheme adopted in the utility model:

An oil palm small-angle fruit ear harvesting knife is composed of a knife point, a knife body and a knife handle. The curved structure, the blade is parabolic, and the two ends of the blade are respectively connected with the tip and handle, so the harvesting knife is composed of a 5-10 degree included angle tip, curved blade body and handle. When harvesting fruit ears, the sharp triangular knife tip can easily penetrate into the smaller cracks, which can cut off the base of the leaves or the fruit stalk relatively smoothly. the

The section of the blade from the back of the blade to the blade is in an inverted equilateral triangle structure. the

The utility model has the advantages of simple structure, low cost, and convenient use. It adopts a knife tip with a small included angle and a curved knife body structure, and can realize fast harvesting with a small angle (less than 20 degrees) between the ear and the base of the blade. The ear has high harvesting efficiency and low harvesting labor intensity, is suitable for popularization and application in the field, and can be used as one of the oil palm ear harvesting tools. the

Description of drawings

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

In the figure: 1. The tip of the knife; 2. The beveled edge on the back of the tip; 3. The body of the knife; 4. The handle of the knife; 5. The tip of the knife. the

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. the

In the structure shown in Fig. 1, a kind of oil palm small angle ear harvesting tool designed by the utility model is made of a knife tip 1, a knife body 3 and a handle 4, and the knife tip 1 is in a sharp triangular structure, The included angle between the tip back slope 2 and the tip blade 5 is 10 degrees, and the beveled side of the tip portion is 12 centimeters long, and the tip is connected with the blade body; It is 5 centimetres, and the thickness of the back of a knife is 30 millimeters, and the arc length of the blade body is 27 centimeters, and the section from the back of a knife of the blade to the blade is an inverted equilateral triangle, and the blade body is connected with the hilt 4. When harvesting oil palm trees with a small angle (less than 20 degrees) at the base of the ear leaves, the knife tip with a 10-degree angle at the front is easy to insert the harvesting knife into the base of the ear leaves, and then use the curved arc Shaped blade and parabolic blade cut off the base of the leaf and the stalk of the ear to complete the harvest. the

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. the
