Description

[Detailed Description of the Invention] A. Purpose of the Invention A. Industrial Application Fields Hard-shelled seeds such as ginkgo nuts and pine nuts are shelled and processed to be used in cooking, confectionery, and food for drinking. It is processed and sold.

Conventional technology: To take out ginkgo nuts and pine nuts, pliers-type devices are used to split the shells, such as Utility Model Publication No. 16535 (1973), Publication Utility Model No. 40-2 (1973).
There is No. 280 or Jikko No. 27-2679, etc., and the seeds are taken out one by one by splitting the shell with pliers.

With such inefficiency, it is not possible to meet the demands that are required in large quantities. Also, recently, a large amount of seeds are put in potspur,
There is a device that uses a vibrator to shake seeds from a hopper onto a seed receiving plate, arrange the seeds in a line, and then place them between upper and lower rollers to crush the shells. The removal of the seeds is efficient, but the adjustment of the rollers for crushing the shells is complicated, and if you do so, you may crush the kernels at the same time as crushing the shells, causing stiffness or damage.
Since the shells are arranged one by one and crushed using a roller, it is difficult to meet current demand.

C. Problems to be Solved by the Invention The conventional method of crushing shells using pliers is inefficient and cannot meet large-scale demands. The shell crushing method using rollers is more efficient than using pliers, but since the seeds vary in size, large seeds are crushed too much and may damage the fruit.
There is an inconvenience that small seeds may fall off the roller without being crushed. The present invention aims to solve these inconveniences and provide a large quantity of unblemished seeds.

B1 Structure of the invention A. Means for solving the problem (B.) One end of an injection pipe (1) made by cutting a strong easter pipe, such as a stainless steel pipe, having an inner diameter slightly larger than the thickness of the seeds to be crushed into an appropriate length. A compressed air adjustment valve (3) (explained in Fig. 3) is fixed to the injection pipe (1) slightly to the left of the screw connecting to the compressed air tank (2), and the injection pipe (1) is connected with the handle (4). ) so that the air pressure inside can be adjusted.

(b) On the left side of the compressed air adjustment valve (8), install the seed discharge tube (
7) Tilt the lower part to the left and insert and secure it into the injection pipe (1) from above. In this case, cut the tip of the seed ejector tube (7) diagonally, and the cut tip will protrude slightly to the left inside the injection pipe (1), and the cut that is not the tip will be cut into the injection pipe (1).
1) so that the seeds are flush with the inner wall of the container, and the seeds are discharged to the left through the opening of the seed discharge port (7). With this configuration, the compressed air collides with the protruding part of the seed discharge tube (7), and the compressed air obtains a weak spiral rotation, and the seeds are also rotated by the spiral rotation of the air, and are jetted while rotating. Move rapidly to the left of pipe (1).

(C) The shell crushing chamber (8) is a cylinder slightly larger than the injection pipe (1), with one end closed and the injection pipe (1) in the center.
Insert and protrude the left end of the holder to secure it.

The other end of the shell crushing chamber (8) is open, and a plate (
A cover (lO), which covers the entire surface of the trowel and has a circular hole cut out in the center from the outside, is screwed and fixed to the opening by pressing the backing plate (9) against the opening.

The back plate (9) has an appropriate thickness, has a dense mesh-like or granular uneven surface on both sides, and has a small hole (l l) with a diameter of about 1 mm in the center. An opening (with an appropriate width and length required for the crushed shells to fall) is located below the cylinder of the shell crushing chamber (8).
12), and a shell crushing chamber (8) is formed such that the distance between the contact plate (9) and the tip of the injection pipe (1) is about 3 cIR.

(d) Install an appropriate number of injection pipes (1) having the above structure in a row under the hopper (5) and fix them to the body frame;
The seed receiving plate (6) is connected to the seed discharge tube σ) by a flexible resin pipe, and the right end of the injection pipe (1) is connected to the compressed air tank (2).

About mouth, operation, and examples Put hard-shelled seeds into the hopper (5), operate the vibrator to guide the seeds to the seed receiving plate (6), fill the compressed air tank (2), and press the valve. When you turn the handle (4) to open the valve, the air will fall from the seed discharge pipe (7) towards the left side of the injection pipe (1), push the seeds and move quickly, reaching the left end of the injection pipe (1). The seeds collide with the air at right angles to the plate (9), and the shells of the seeds are crushed by the impact, and the seeds and shells are separated from the opening (
12) Fall below. In this case, since the small hole (11) is provided in the center of the contact plate (9), the center of air pressure is the small hole (11).
11), the seeds are pushed by this force and collide with the contact plate (9) at right angles. Since the surface of the plate (9) is provided with a net-like or granular uneven surface, the seeds collide with the plate (9) at right angles without slipping sideways when colliding with the plate (9). The shell crushing effect is good.

As a result of the experiment, 100% of the shells were completely crushed regardless of the size of the seeds. The crushed shells and fruits are pushed down by the strong wind through the entrance (12) installed at the bottom of the shell crushing chamber (8), but if the fruit is hard like the silver and gold leaf, the plate below will be hard. However, very soft fruits such as pine nuts may be damaged when falling, so a small mesh net or cloth is appropriate for catching them below, but the net is particularly suitable for protecting against wind. It is thought that it is better to use a net than cloth because it is more suitable for dispersing rice power.

Effects of the C1 invention: 100% complete crushing of hard-shelled seeds regardless of their size.

It is recognized that the crushing effect is sufficient if the length of the mouth and injection pipe is about 1 mm, so it is possible to downsize the machine.

C. It is highly economical because the injection pipe can be used depending on the amount of seeds to be crushed by operating the valve handle.

Second, the production cost is low.

It has the following advantages. 1
