To separate.

The suction unit 30 includes a suction port 31 through which a foreign material exposed in the soil mixture passed through the digging unit 20 is sucked, and a suction line 32 forming a transport path of the foreign material sucked through the suction port 31 and , A suction header 33 forming a transport path of a foreign material transferred through the suction line 32, a cyclone 34 for rotating foreign substances supplied from the suction header 33 by suction force, and a cyclone by suction force Exhaust line 35 forming a path through which air is discharged from 34, exhaust drive unit 36 coupled to exhaust line 35 to provide suction force, and cyclone to maintain internal depressurization state of cyclone 34 It may include a vacuum rotary 37 to block the outlet 343 of the (34), or to maintain the closed state of the outlet 343 of the cyclone (34).

In addition, the suction header 33 is connected to the first line 321 and the second line 322 to form a transport path for foreign matter.

Here, the area of the first inlet 311 is formed to be larger than the area of the second inlet 312 to smoothly inhale foreign substances that are not inhaled during the first inhalation. When the area corresponding to the width direction of the belt portion is L, and the length corresponding to the transfer direction of the soil mixture is W, the area of the first entrance 311 is represented by L * W1. It can be, the area of the second entrance 312 can be represented by L * W2, by establishing a relationship W1> W2, larger than the first entrance 311 in the second entrance 312 having a relatively narrow entrance It can have suction power.

In addition, the cross-sectional area of the first line 321 (inner diameter a1) is larger than the cross-sectional area of the second line 322 (inner diameter a2), so that the first line having a relatively large cross-sectional area (inner diameter) ( In 321), a suction amount greater than that of the second line 322 can be facilitated.

For example, the cross-sectional area of the first line 321: The cross-sectional area of the second line 322 may be represented by a ratio of 10: 5 to 10: 9. More preferably, the cross-sectional area of the first line 321: The cross-sectional area of the second line 322 may be represented by a ratio of 10: 7 to 10: 8. If it is lower than the lower limit of the ratio, the suction at the second entrance 312 and the second line 322 is not smooth due to excessive suction at the first entrance 311 and the first line 321, and the size of the foreign matter In response to this, a foreign material may block the second entrance 312 or the second line 322. If it is larger than the upper limit of the ratio, the difference between the suction force at the first inlet 311 and the first line 321 and the suction force at the second inlet 312 and the second line 322 is insufficient, so that Foreign matter will not be inhaled.

Therefore, by defining the ratio between the cross-sectional area of the first line 321 and the cross-sectional area of the second line 322 and the corresponding cross-sectional area of the first inlet 311 and the second inlet 312, the difference in suction force is clearly defined. This makes it possible to completely inhale foreign substances contained in the earth and sand mixture.

Typically, the cross-sectional area (π (a1 ^ 2)) of the first line 321 and the cross-sectional area (π (a2 ^ 2)) of the second line 322 are the cross-sectional area (π (a3 ^ 2) of the suction header 33. )).

The cyclone 34 exhibits a truncated cone shape with a larger upper portion and a smaller inner diameter toward the lower portion. The upper side of the cyclone 34 is provided with an intake port 341, and the air containing foreign matter introduced through the intake port 341 is rotated along the side in the interior of the cyclone 34 by the suction force. In addition, a discharge port 343 is provided at a lower portion of the cyclone 34, and a foreign material falling by a load can be discharged from the discharge port 343. In addition, the upper central portion of the cyclone 34 is provided with an exhaust port 342, and only the air inside the cyclone 34 can be discharged through the exhaust port 342.

The exhaust line 35 connects the exhaust port 342 and the exhaust drive unit 36.

The vacuum rotary 37 is formed in a radial shape from a hollow vacuum housing 371 and a vacuum shaft 374 coupled to the outlet 343 of the cyclone 34 in communication, and supported or adhered to the inner wall of the vacuum housing 371 It may include three or more vacuum impeller 373, and a vacuum drive unit 375 for intermittently rotating the vacuum impeller 373 corresponding to the number of vacuum impellers 373.

When the foreign matter inside the cyclone 34 enters the exhaust driving part 36, it causes a failure of the exhaust driving part 36, and the durability of the exhaust driving part 36 decreases, the life span decreases, and air pollution due to the release of air to the atmosphere There was a problem.

To solve the problem, as the vacuum rotary 37 is provided, foreign matter falls inside the cyclone 34, and only air moves to the exhaust driving unit.

In more detail, the cyclone 34 must maintain a negative pressure therein to increase the separation efficiency of foreign matter and air from inside the cyclone 34. In addition, in order to discharge the foreign matter dropped to the outlet 343 of the cyclone 34, the outlet 343 should be periodically opened periodically, but when the outlet 343 is opened, the internal negative pressure of the cyclone 34 is maintained. However, a problem arises in that foreign matter is transmitted to the exhaust driving part 36 through the exhaust port 342 and the exhaust line 35 by suction force.

Here, the internal negative pressure state of the cyclone 34 is not a physical vacuum state, and is defined as a low pressure generated by the exhaust driving part 36 inhaling the internal air of the cyclone 34 with the exhaust port 343 blocked.

Here, although four vacuum impellers 373 are shown, three or more vacuum impellers 373 are centered on the vacuum shaft 374 in correspondence with the diameter of the discharge port 343 or the area of the discharge port 343. It can be arranged radially at equal intervals.

In addition, the plow portion 242 of the first digging unit 20a and the plow portion 242 of the second digging unit 20b are cross-arranged based on the transfer direction of the soil mixture, so that foreign matters contained in the soil mixture are excavated. It can be stably exposed to the upper side of the mixture.

In addition, through the detailed configuration of the suction unit 30, foreign substances exposed by the first digging unit 20a as well as foreign substances exposed by the second digging unit 20b can be separated by suction power, and 1 Even foreign substances that are not inhaled can be stably inhaled by the secondary inhalation force.

In addition, in response to the formation of the negative pressure (vacuum) inside the cyclone 34, the body time of the foreign matter is increased in the cyclone 34, and the negative pressure (vacuum) inside the cyclone 34 can be stably maintained, and the cyclone 34 Only the air from the inside is discharged to the exhaust line 35, and it is possible to maximize the ability to collect foreign substances.

In addition, the balance between the exhaust pressure through the exhaust driving part 36 and the dust collection pressure through the dust collecting driving part prevents the negative pressure (vacuum) state inside the cyclone 34 from being broken, and the foreign material from the cyclone 34 exhaust line 35 ) Is prevented, and damage or deterioration of the exhaust driving unit 36 can be prevented.

In addition, a pressure balance point can be maintained through a difference in cross-sectional area (inner diameter) of the first line 321 and cross-sectional area (inner diameter) of the second line 322, and it is possible to prevent a foreign matter from being lowered in suction power. . In response to the difference in cross-sectional area (inner diameter) of the first line 321 and the cross-sectional area (inner diameter) of the second line 322, the cross-sectional area of the first inlet 311 and the second inlet 312 is different, so that 2 It is possible to maximize the efficiency of inhalation of foreign substances in the car inhalation process.

In addition, it is possible to smoothly discharge foreign substances while maintaining a continuous vacuum equilibrium point by stably maintaining the negative pressure inside the cyclone 34 through the vacuum rotary 37.
