Description

A three-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 three-edged harvesting knife for oil palm fruit 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 of harvesting fruit ears: one is when the tree body is high, use a "scimitar-shaped" harvesting knife to extend 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 The "straight knife" harvesting knife directly cuts off the fruit stalk outside the leaf axil and takes out the ear. In production, when the tree body is low, the harvesting knife used: has three blades, the front blade is straight, the two side blades are oblique, 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 harvesting the ears 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). If the width of the blade is the same, the blade of the harvesting knife will be stuck in the gap, resulting in a very time-consuming and laborious harvesting, and the cost of oil palm ear harvesting will increase and the efficiency will be low.

Utility model content

The purpose of the utility model is to provide a three-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 lower body, can reduce the harvesting intensity, and improve the harvesting work efficiency.

The technical scheme adopted in the utility model:

A three-edged harvesting knife for oil palm ears, consisting of a blade, a blade body and a handle, the front and two sides of the blade are designed as blades, the front blade is linear, and the side blades are oblique. The cross-section of the blade is an equilateral triangle structure, which can increase the structural hardness of the blade; the blade body is in an isosceles trapezoidal structure, and its upper and lower ends are respectively connected with the blade and handle, thus forming a harvesting tool for harvesting ears When holding the knife handle, you can directly use the front and side blades to cut off the leaves or the base of the fruit handle.

The length of the lateral side at the junction of the knife body and the handle is greater than the length of the front side of the blade.

The utility model has the advantages of simple structure, low cost, and convenient use. It adopts an equilateral triangle blade and an isosceles trapezoidal blade structure, and the structure design is reasonable. It can realize rapid harvesting of lower fruit ears and leaves of the oil palm tree, and the harvesting efficiency is high. 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 the structural representation of the utility model.

In the figure: 1. blade; 2. front blade; 3. side blade; 4. blade body; 5. 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 three-edged type harvesting knife designed by the utility model is made of blade 1, blade body 4 and handle 5, and the front and two sides of described knife 1 are designed It is blade portion, and its front blade portion 2 is straight line, and long 8 centimetres, and side blade portion 3 is oblique line shape, and the cross section of blade 1 is equilateral triangle structure; Described blade body 4 is isosceles trapezoidal structure, and hypotenuse length is 18 centimeters, the upper end width is 10 centimetres, is connected with blade 1, and the lower end is connected with handle of a knife, thus constitutes harvesting cutter. When harvesting the ear leaves with a lower tree body, use the front blade 2 to conveniently cut off the petiole and ear stalk at the base of the ear blade, and use the side blade 3 to facilitate the harvesting knife to break away from the "knife gap" for harvesting. Harvest.

The above is only the preferred embodiment of the utility model, 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.
