Description

Extrusion screw for agricultural products extracting apparatus

The present invention relates to an extrusion screw for an agricultural product juicer, and more particularly, to an extrusion screw for an agricultural product juicer that can quickly and simply replace a worn spiral brush part.

In general, agricultural products such as vegetables or fruits with a lot of fiber such as radishes, onions, or cabbage are used by extracting juice. As such, an agricultural product squeezing device is used to obtain juice by grinding and pulverizing a large amount of agricultural products.

And the conventional agricultural products squeezing device is generally formed with a supply port for supplying agricultural products to the upper side, a housing having an outlet formed in the lower part, a shaft installed inside the housing, and a cutter for cutting the agricultural products supplied through rotation, It is installed in the lower part of the housing and is formed of a mesh material and consists of an extrusion pipe for discharging juice while transporting agricultural products, and a screw installed inside the extrusion tube to extrude the pulverized agricultural products.

The extruded tube is composed of an inlet part with an open top to receive the agricultural products discharged from the housing, a transfer part for transferring agricultural products from the inlet part, and a funnel-shaped discharge part through which the transferred agricultural products are discharged, the inlet part and the transfer part; The discharge part is configured to be fastened with a bolt and a nut through a flange formed at an end, respectively. In addition, the extruded tube is formed of a mesh material for all of the inlet, transfer, and outlet.

By the way, the screw constituting the conventional agricultural product juicer is an extrusion screw for extrusion and consists of a configuration in which a spiral screw is simply formed on the outer surface of the shaft.

Therefore, in the case of squeezing agricultural products such as vegetables or fruits with a lot of fiber in the conventional agricultural product squeezing device including the extrusion screw, the fibrous pinching phenomenon occurs on the mesh body of the extrusion pipe, and smooth juice is not achieved and at the same time, the fiber is caught. There was a problem that caused damage to the extruded tube due to the phenomenon.

Accordingly, in order to solve the above problems, the "extrusion screw for agricultural products juicer" (hereinafter referred to as "conventional extrusion screw for agricultural products juicer") of Korean Patent Registration No. 2163162, which was previously applied and registered by the present applicant, is known. there is.

Extrusion screw for agricultural products juicer in the related art is applied to agricultural products juicer, installed inside the extrusion pipe and rotationally driven through a driving means to extrude agricultural products and transport agricultural products in an extrusion screw for agricultural products juicer, a shaft which is tapered by a certain length at the end; It is provided spirally wound around the outer surface of the shaft, and includes a screw that allows agricultural products to be extruded and transported in one direction when the shaft is rotated, while preventing the fiber from being caught on the inner surface of the extruded tube made of a mesh material. , The fiber removal tool is installed and fixed through the bolt and nut, which are fixing means, while the installation block is interposed on the outer surface of one side of the screw at regular intervals in the spiral direction of the screw.

The fiber removal device is configured to include a brush block provided in a block type having a predetermined width, and a brush protruding into a plurality of strands at a predetermined interval on the upper surface of the brush block.

Therefore, the conventional extrusion screw for a juicer is composed of a screw wound around the outer surface of the shaft in a spiral with respect to the extrusion screw, and a fiber removal tool installed and fixed at a predetermined interval in the screw direction is applied to the outer surface of one side of the screw. When juicing agricultural products, such as, it is possible to stably prevent the fibrous trapping phenomenon on the mesh body of the extrusion tube, and through this, it has the advantage of maximizing the juice efficiency by facilitating the juice extraction.

However, in the conventional extruding screw for a juicer configured as described above, when the brush of the fiber removal device wears out during use, a plurality of fiber removal devices have to be replaced one by one. I had.

In addition, the conventional extruding screw for a juicer has a problem in that it takes a long time to manufacture the extruded screw and increases the manufacturing cost by manually installing the fiber removal port on the outer surface of one side of the screw through the fastening of bolts and nuts.
