Pull-type cyperus esculentus harvester

Abstract

A traction-type oily bean harvester, including a harvesting mechanism, a conveying mechanism, a screening mechanism and a collecting mechanism on the car body. The transmission mechanism and the screening mechanism are respectively driven by the gearbox on the car body through the transmission mechanism. The ripper, planer and recovery board under the front part are composed of the conveying mechanism consisting of the conveying chain plate and the matching sprocket. The screening mechanism is a double-layer vibrating screen. The collecting mechanism is composed of a bean storage box, a double-layer collection box and The bean storage box is arranged in the middle of the car body, the upper layer of the double-layer collection box is the impurity box, and the lower layer is the transfer box. In the present invention, the mixture of oily beans and soil is planed out by a soil planer, transported to the screening mechanism by a conveying mechanism, and the impurities and oily beans are screened out, and then fall into the impurity box and the transfer box respectively, and then the oil in the transfer box is removed by a hoist. The sand beans are transported to the bean storage box. The whole mechanism is compact, the power transmission is clear, the residue is small, and the separation effect is good, which solves the problem that the oil sand beans are easy to grow and difficult to harvest.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to an oily bean harvester pulled by a tractor. Background technique [0002] The origin of oily bean is Africa. It is a high-quality, high-yield, and high-value comprehensive new crop for oil and grain. Yousha beans are rich in unsaturated fatty acids, sugars, starch, and 17 kinds of amino acids, which are extremely nutritious, and the oil content of Yousha beans is as high as 35%, and the oil yield is generally about 35%, and the quality is better than rapeseed oil , Known as "underground walnut". Because of its high economic value, strong adaptability, and easy management, it has been planted on a large scale in my country in recent years. [0003] The oily sand bean grows grass on the ground and bears fruit underground. Although the oily sandy bean is easy to plant, the fruit is easy to fall off because of its thin root stalk. The time is also very long, and there will be a large amo...

Problems solved by technology

[0003] The oily sand bean grows grass on the ground and bears fruit underground. Although the oily sandy bean is easy to plant, the fruit is easy to fall off because of its thin root stalk. The time is also very long, and there will be a large amount of fruit remaining in the soil, which is not easy to harvest, which will bring greater economic losses to the growers and seriously affect the enthusiasm of the growers.

[0004] At present, most of the existing oily bean harvesters are equipped with various mechanisms on the body of the harvester in sequence, coupled with the traction of the tractor, the length of the body is finally very long, and it is difficult to operate, especially when it is necessary to turn. The turning radius is too large, it is not easy to turn, and the car body is too long, which also causes problems such as too many layers of the transmission mechanism, low transmission efficiency, and large power loss. Therefore, the harvesting efficiency of the existing oily bean harvester is not ideal. Or, the bean storage box of existing bean harvester is arranged at the rearmost part of car body mostly, can only use the less bean storage box of capacity because of guaranteeing the balance before and after the car body like this, for large-area land like this Harvesting of blocks would be inconvenient
