Description

Grain grinder with bypass passage {A mill for grain with bypass duct}

The present invention relates to a grain grinder, specifically, by bypassing the wind pressure generated in the process of finely grinding a variety of grains, such as rice, barley, soybeans, corn, wheat by forming a separate air bypass passage, The present invention relates to a grain grinder having a bypass passage to prevent breakdown of the machine while grinding is performed.

A general grain grinder is a configuration in which grain is sucked together with air by an impeller installed therein when the grain is put into the hopper, and finely crushed by a grinder installed with the impeller to be collected at a lower outlet.

However, such a grain grinder is a fine dust generated during the grinding process is not completely discharged to the outside of the hopper is accumulated in the grain mill body causes a failure of the device.

In order to improve this problem, Utility Model Registration No. 242155 discloses the implementation means in detail.

Referring to Figure 1, the grain conveyed by the screw 110 of the grain grinder 100 is moved down through the hopper 130, wherein the grain powder pulverized by the grinding impeller 150 is discharged ( 190 is collected, the fine dust generated during the crushing process is discharged to the dust hole 170 drilled on the upper portion of the discharge chute 180, the discharged shells are collected by the bag 200 and the flow air of the bag It is discharged through the pores.

However, the above-described grain grinder was also the same as the fine dust passing through the pores of the bag is collected inside the device is causing the failure of the device.

Therefore, an object of the present invention has been proposed to solve the above-mentioned problems, a separate air bypass passage so that the fine dust or shell generated in the process of grinding the grain is accumulated inside the grain grinder to cause the failure of the device It is an object to provide a grain grinder having a bypass passage to form a, to prevent the introduction of fine dust into the body.

The characteristics of the grain grinder having a bypass passage according to the present invention for achieving the above object,

In the grain crusher for transferring the grain fed to the inlet when the transfer motor is rotated, and the grain conveyed by the screw to the hopper to grind into fine powder with a rotating grinding impeller to transport the discharge to the lower discharge chute in the And an air opening passage formed at an upper side of the discharge chute and one side of the hopper, and an air bypass passage connecting the two openings to circulate the wind pressure generated inside the grain grinder, and fixedly coupling the air bypass passage. It includes a fixed plate and a strainer that is mounted inside the fixed plate to pass air and block grain powder.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a cross-sectional view showing the interior of the grain grinder having a bypass passage according to the present invention, Figure 3 is a perspective view of the main portion of the grain grinder having a bypass passage, Figure 4 is an enlarged view of a portion A of FIG.

2 to 4, an inlet 12 is formed at an upper portion of the main body 10, and a screw 14 that rotates the grains injected into the inlet 12 by receiving power from the transfer motor 16. ) Is placed, and the grain introduced by the screw 14 is transferred to the hopper 15.

The lower part of the hopper 15 is equipped with a crushing impeller 26 that receives power from the drive motor 20 and rotates through the belt 22 and the rotating shaft 24.

The grain transferred to the hopper 15 is guided to a predetermined position of the grinding impeller 26 by the guide partition 18 serves to smooth the grinding.

A discharge chute 37 having an outlet 38 formed at the lower end of the hopper 15 is positioned, and the dustproof packing 28 is fixedly coupled to a portion where the hopper 15 and the discharge chute 37 abut. It serves to seal and dustproof, and to connect the discharge chute 37 and the hopper 15 to form an air bypass passage 34 to bypass the flow air generated from the crushing impeller 26 It is.

The air bypass passage 34 connects the opening 31a formed at the upper portion of the discharge chute 37 with the opening 31b formed at one side of the hopper, and constitutes a passage, and inside the fixing plate 33a and 33b. In the sieve (32a, 32b) is equipped with air to pass through most of the grain powder is cut off the pulverized grain powder from the crushing impeller 26 is transferred to the discharge port 38 is loaded, the crushing impeller 26 The rotating air generated while rotating serves to circulate the flowing air by bypassing the discharge chute 37 toward the hopper 15 again.

The sieve (32a) (32b) is preferably finely woven fibers, it is to be used to select the finely woven so that the pulverized grain powder can not escape.

In addition, the vibrator 30 mounted at the lower portion of the discharge chute 37 serves to finely vibrate the discharge chute 37 so that the pulverized grain powder is collected at the lower part of the discharge port.

Block door 36 for opening and closing the outlet 38 is opened and closed by a hinge (not shown), the hook is mounted on the outside of the blocking door 36 to close and secure the blocking door 36 ( At one side of the 40 and the discharge chute 37, a latch 41 is attached.

In addition, an air hose 35 is installed at the upper end of the grinding impeller 26 for the purpose of preventing the accumulation of grain powder.

The air hose 35 is a wind pressure that is bypassed to the air bypass passage 34, and a hose of a predetermined length is connected to the upper end of the grinding impeller 26 from the opening 31a.

Referring to the operation of the grain grinder having a bypass passage according to the present invention configured as described above are as follows.

As shown in FIG. 5, the grains introduced into the inlet 12 are transferred to the hopper 15 by the rotation of the screw 14, and the conveyed grains are fixed by the guided partition 18 by the fixed impeller 26. When guided into position, it is pulverized into fine particles by the pulverizing impeller 26 rotating at high speed.

The pulverized grain powder is accumulated toward the discharge port 38 along the discharge chute 37 which is vibrated finely by the vibrator 30.

At this time, the flow air generated while the grinding impeller 26 rotates at a high speed flows into the opening 31a formed at the upper portion of the discharge chute 37, and the hopper 15 located at the upper portion along the air flow passage 34. The flowing air continues to circulate while being bypassed through the formed opening 31b.

If the grain powder pulverized in the crushing impeller 26 passes through the gap of the sieve 32a, it does not flow out because it flies in the crushing space of the crusher.

On the other hand, the air hose 35 is installed on the upper part of the crushing impeller 26 so that the fine powder is not accumulated on the upper part of the crushing impeller 26 so as to smoothly discharge.

The present invention as described above, by forming a separate air bypass passage to bypass the wind pressure generated in the process of crushing grains using a grain grinder can be circulated by a smooth grinding operation can be made and extend the life of the device There is an advantage to this.
