Description

Equipment for continuous grinding of cereals {Apparatus for grinding cereals continuously}

The present invention relates to an apparatus for continuously polishing cereals, and more particularly, to an apparatus for continuously polishing cereals for removing various foreign substances during commercialization processing of various cereals.

Grains such as rice, barley, and beans go through a process of polishing the surface for steelmaking and taste functions. In the case of a rice milling machine, the skin of the threshed rice is cut with a stripping machine, and then the brown rice is processed into white rice. In any case, since foreign substances such as stones, skin powder, and crushed powder are mixed or generated during the graining process, various devices are mobilized for treatment. Of course, it is important to make the work of separating grains and foreign substances separately in such a device.

As prior art documents that can be referred to in this regard, the following Korean Patent Application Publication No. 2003-0068523 (priority document 1), Korean Patent Application Publication No. 0738740 (priority document 2) and the like are known.

Prior Document 1 blocks overload by inhaling grain and external air with the suction induction part, and the separated foreign matter is discharged by pressing a rubber piece that rotates in close contact with the discharge hole while separating it into grain and foreign matter in the grain separation part. Therefore, it prevents foreign substances from blocking the discharge hole, and prevents clogging by separating foreign substances from the surface of the filtration filter by impacting the filter filter.

Prior Document 2 is a driving plate that is rotated by a motor by attaching a friction pad; With a friction pad attached to the drive plate and a pressurizing plate capable of adjusting the separation distance; While pressing the grain with the driving plate and the pressurizing plate, the skin is removed by rubbing the driving plate and the pressurizing plate. Accordingly, the effect of minimizing damage to grains is expected while removing them regardless of the type, thickness, and shape of the grain.

However, according to Prior Document 1, the size of the rubber piece is constant and thus it is difficult to apply to various grains, and according to Prior Document 2, it is difficult to continuously input the grain between the driving plate and the pressurizing plate.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention proposes an apparatus for continuously grinding grains. It targets devices that polish the surface of grains such as rice, barley, and beans, but is not limited thereto.

The main body 10 according to the present invention has a structure having an input hopper 15, a collection hopper 16, and a discharge hopper 17 around a concentric drive shaft 11 and a mesh-shaped outer cylinder 13. The main body 10 has a grain conveying path with the input hopper 15 as the upstream side and the collection hopper 16 and the discharge hopper 17 as the downstream side. At the center of the conveying path, the drive shaft 11 and the outer cylinder 13 are concentrically arranged. The drive shaft 11 is rotatably supported by the body 10 and both ends are exposed to the outside. The outer cylinder 13 is a cylindrical screen having a net for permeating foreign matter, and is installed to facilitate replacement by opening the cover on one side of the main body 10.

Here, the collection hopper 16 is a duct for collecting grains from which foreign substances have been removed, and the discharge hopper 17 is a duct for discharging the removed foreign substances.

As a detailed configuration of the present invention, the outer cylinder 13 of the main body 10 is characterized in that it forms a gradient with an inner diameter that is differentiated at an upstream end and a downstream end.

If the inner diameter of the outer cylinder 13 is constant, it is insufficient to cope with the condition of continuously inputted grains. That is, it is difficult to differentiate the grinding conditions according to conditions such as the type (grain size) of the grain, the amount of input, and the moisture content. When the inner surface of the outer cylinder 13 forms a gradient, flexible control in connection with the adjustment means 30 to be described later is possible. The outer cylinder 13 is applied in a structure in which the inner diameter decreases from the upstream end to the downstream end. However, the difference in the inner diameter at the upstream end and the downstream end of the outer cylinder 13 may not be large.

Further, according to the present invention, the bending means 20 for rotatably accommodating the inner cylinder inside the outer cylinder 13 has a structure including a transfer screw 24 and a brush 26 on the outer peripheral surface of the inner cylinder. The straightening means 20 is based on an inner cylinder mounted on the drive shaft 11 while maintaining concentricity with the outer cylinder 13. The inner cylinder is composed of an upstream cylinder 21 disposed in a partial area of the upstream end and a downstream cylinder 22 disposed in most of the area. The transfer screw 24 of the upstream barrel 21 pushes the grains input from the upper side to the downstream side to transfer them. The brush 26 mounted on the outer circumferential surface of the downstream cylinder 22 induces polishing by intimately contacting the conveyed grain to the inner surface of the outer cylinder 13 and pressurizes the removed foreign matter to be discharged through the outer cylinder 13. The brush 26 is made of a resin material having a high coefficient of friction while having elasticity and abrasion resistance.

As a detailed configuration of the present invention, the brush 26 of the straightening means 20 is intermittently disposed vertically and horizontally through the support 28, and the support 28 supports the brush 26 so that the posture can be changed. It is characterized.

Referring to FIG. 2, a state in which a brush 26 having a size corresponding to approximately 90° from the outer circumferential surface of the downstream cylinder 22 is disposed is illustrated. In FIG. 2, the brushes 26 are arranged in 4 rows when viewed in the longitudinal direction of the drive shaft 11, and in FIGS. 1 and 3, the brushes 26 are alternately arranged in 4 rows and 5 rows in the transverse direction in the radial direction of the driving shaft 11. Is placed. In this case, the brush 26 forms a total of 18 intermittent arrangements. Each brush 26 maintains an L-shaped bent state through the support 28 to increase elasticity acting on the grain. When the brush 26 is arranged in a spiral shape similar to the conveying screw 24, the conveying force and friction force for the grain are increased. In this case, the support 28 is formed in a structure that is coupled to allow a change in posture on the downstream cylinder 22.

In addition, according to the present invention, the adjusting means 30 has a structure in which the distance between the inner surface of the outer cylinder 13 and the brush 26 is varied. The adjusting means 30 changes the gap formed by the brush 26 and the inner surface of the outer cylinder 13 in connection with the gradient structure of the outer cylinder 13 described above.

As a detailed configuration of the present invention, the adjustment means 30 is connected to induce axial movement of the inner cylinder through an adjustment shaft 31 and an adjustment shaft 31 mounted to be axially movable at one end of the drive shaft 11 It is characterized in that it comprises a connecting pin (32), a slider (34) for rotatably supporting the outer end of the adjustment shaft (31), and a driver (46) connected to induce a linear motion of the slider (34).

Referring to FIG. 4, a state in which the adjusting means 30 is connected to the drive shaft 11 on the outer surface of the main body 10 is clearly revealed. A separate case is mounted on the outer surface of the main body 10. The adjustment means 30 is composed of an adjustment shaft 31, a connection pin 32, a slider 34, a driver 46, and the like. The drive shaft 11 has a slot portion 11a adjacent to the lower end of the downstream cylinder 22. The adjustment shaft 31 is connected to the downstream cylinder 22 via a connection pin 32 at the upstream end, and has a disc-shaped collar portion 31a at the downstream end. The connection pin 32 penetrates the slot 11a of the drive shaft 11 and causes an axial movement. The slider 34 is slidably mounted at the lower end of the case and is connected to the driver 46 upwardly.

At this time, the slider 34 may be directly connected to the servomotor type actuator 46, but it is preferable to use a geared motor through the worm gear 35 in terms of durability. In this case, teeth 34a are formed on one surface of the slider 34, the worm of the worm gear 35 is connected to the driver 46, and the worm wheel of the worm gear 35 and the pinion 36 concentric with the slider 34 ) Of the teeth (34a).

On the other hand, the worm of the worm gear 35 may be further provided with a manual knob 38. Since the manual knob 38 is exposed to the outside of the case, it is convenient for the operator to manually operate it.

In addition, according to the present invention, the control means 40 is a structure for controlling the operating state of the bending means 20 and the adjusting means 30. The control means 40 is based on a controller 42 equipped with a microprocessor, a memory, and an input/output interface. The controller 42 is provided with a touch screen for displaying and indicating an operating state.

As a detailed configuration of the present invention, the control means 50 detects the operation state of the graining means 20 and the adjusting means 30 by inputting a signal from the detector 44 from the controller 42, and It is characterized in that the output applied to the driver 46 is varied in response to the steady state.

In FIG. 3, a state in which the detector 44 is installed inside and outside the main body 10 is virtually illustrated. The detector 44 may select a configuration that is selectively distributed to a plurality of points to detect the particle size, input amount, and moisture content of the conveyed grain, as well as the state of removing foreign substances. The detector 44 is connected to the input interface of the controller 42, and the driver 46 is connected to the output interface of the controller 42.

As an example of operation, the raw material that is first selected and input to the input hopper 15 is continuously transferred inside the outer cylinder 13, and the grains polished while passing through the graining means 20 are discharged to the collection hopper 16. Then, the removed foreign matter is discharged to the discharge hopper 17 through the outer cylinder 13. If the state of the raw material is changed, the controller 42 immediately detects it with the detector 44 and outputs it to the driver 46 to adjust the gap between the outer cylinder 13 and the brush 26. For example, if the grain size is increased depending on the variety of rice, the gap between the outer cylinder 13 and the brush 26 is also slightly increased to prevent a phenomenon in which the quality is deteriorated or crushed due to excessive grinding of the grain.

It is apparent to those of ordinary skill in the art that the present invention is not limited to the disclosed embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such variations or modifications will have to belong to the claims of the present invention.
