Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a device for threshing raw peanuts.

(b) Conventional technology Conventionally, peanuts are dug up from the ground together with branches and leaves, and then they are shredded, that is, removed from the branches and leaves.
Such grain removal work is performed manually or by using a grain removal device.

Such a threshing device, like a normal threshing device,
A handling barrel with handling teeth protruding from its circumference is rotatably mounted on a shaft, and by moving the harvested peanuts with branches and leaves along the circumferential surface of the rotating handling barrel,
The handling teeth are used to remove peanuts from the branches and leaves.

(c) Problems to be Solved by the Invention However, when the above-mentioned grain removal work is performed manually, there are problems in that it is labor-intensive and time-consuming, and the work efficiency is poor.

Furthermore, when using a pulverizing device, there is a problem that the pulverizing efficiency is poor unless the raw peanuts harvested together with the branches and leaves are dried in advance.

In other words, peanuts are attached to branches through the ovary stalk, and while the tip of the ovary stalk can be easily removed from the branch, the base end of the ovary stalk can be easily removed from the peanut pod. Therefore, after threshing, if the ovary stalk is attached, the ovary stalk must be removed manually, which is a hassle, and this reduces work efficiency.

In addition, there is a problem in that peanuts are easily damaged if they are shed by the handling teeth.

Another problem is that dried peanuts have a poorer taste than fresh peanuts (those that have been boiled with salt as a post-treatment).

For this reason, it has been desired to develop a device that can efficiently shred peanuts in their raw state.

(d) Means for solving the problem Therefore, in the present invention, a pair of upper and lower brush mounting shafts are mounted rotatably in the grain removing case, a grain removing brush is attached to the circumferential surface of each mounting shaft, and both grain removing brushes are connected to each other. A shedding part is formed between the tips to remove the raw peanuts attached to the branches and leaves while rotating from above and below, and a raw peanut supply port is provided in the shedding case to supply the branches with raw peanuts attached to the shedding part. It is an object of the present invention to provide a device for threshing raw peanuts, which is characterized by the following.

Another feature is that the grain removal brush is molded from nylon.

(e) Effects According to the present invention, the following effects occur.

That is, in the present invention, by supplying the branches and leaves with raw peanuts to the shedding part from the raw peanut supply port, the raw peanuts can be shredded while the pair of upper and lower shedding brushes rotate from above and below. can.

At this time, the shedding brush is made of nylon that has wear resistance and elasticity, so that it can reliably sheed the raw peanuts without damaging the raw peanuts.
