Blow-holes 45 ejecting compressed air to the soil surface while communicating with a blast source are formed at an excavating cylinder port 40a at a lower end faced to the soil surface in the excavating cylinder 40. In an excavator for soil constituted in this manner, the excavating cylinder ort 40a is rotated by a hydraulic motor 48 while a cutting tip 46 fixed so as to be downward projected from the circumferential edge of the lower end of the excavating cylinder port 40a is mounted.

| PURPOSE: To more efficiently discharge slurry by slurrifying the earth and sand excavated from the front side of a buried small-diameter pipe and sucking the slurry by connecting a slurry pipe to a vacuum suction device. CONSTITUTION: After a pilot pipe 5 is buried by driving the pipe 5 toward a vertical shaft 7 by means of an excavating machine 1, a small-diameter pipe 6 is connected to the rear end of the pipe 5 and driven and buried by means of the machine 1 while the natural ground is excavated by means of an excavating head 8. In addition, the earth and sand taken in the head 8 are slurrified by providing a water tank 10 and a water pump 11 on the ground on the vertical shaft 7 side and supplying fresh water to the head 8 from the pilot pipe 5 through a water pipe 12. Then the slurry is made to flow in a slurry pipe 14 in the pilot pipe 5 and sucked by means of a vacuum suction device 17 through a slurry flow rate measuring instrument 15 and a control valve 16 installed on the ground. Therefore, cost can be reduced remarkably. | ||||||

| PURPOSE: To enhance workability by installing a vacuum pump which sucks up and conveys excavated earth and sand crushed with a cutter by way of a discharge pipe and a receiver tank which separates the excavated earth and sand from an air and an outside discharge means which discharges the excavated earth and sand to the outside. CONSTITUTION: Excavated muck collected together in a chute 8 is sucked up from a suction pipe 18 by driving a vacuum pump 12 and arranged to flow into a receiver tank 13 by way of a discharge pipe 19. Then, the excavated earth and sand separated from the air in the tank 13 is discharged in the rear side of an excavating machine based on a muck truck transportation method or a fluid (muddy water) transportation method. Then, as an occasion demands, an air flow-in pipe from a compressor is connected to a suction part of the discharge pipe 19 where compressed air is sprayed, thereby preventing excavated muck from being clogged. Furthermore, filter tanks 14a and 14b are interposed on the way of the tank 13 and the pump 12, thereby catching finer excavated earth and sand. This construction makes it possible to convey the excavated earth and sand backward easily and enhance an environment inside a pit and its maintenance quality as well. | ||||||

| PURPOSE: To reduce an operating load of a vacuum car by way of reducing the amount mud by supplying the sludge water emerged during or after excavating to a liquid cyclone, concentrating the sludge water and carrying out the concentrated sludge water by the vacuum car. CONSTITUTION: Mud in a hole 2 containing sediment excavated by an excavator 1 is treated by a sediment separation device 3, coarse grains are separated, the mud is put in a precipitator 6, and returned into the hole 2 and circulated. In the meantime, in the case when the specific gravity of the drilling mud in the precipitator 6 exceeds a specific gravity range suitable for a continuous underground wall, the drilling mud in the precipitator 6 is supplied to a liquid cyclone 11 as sludge water, and new drilling mud is properly put in the precipitator 6 or the hole 2. Thereafter, the drilling mud concentrated in the liquid cyclone 11 is taken out as cyclone under and put in a concentrating tank 21. Dimension of each part of the liquid cyclone is adjusted so that the specific gravity of the supplied drilling mud becomes moderate. Thereafter, the concentrated drilling mud in the concentrating tank 21 is delivered to a vacuum car as a carrier means by a pump 22, and it is taken out to a specified intermediate disposal plant.

| 133 | Method of disposing excess concrete for concrete pile placed in position | JP1533494 | 1994-02-09 | JPH07216876A | 1995-08-15 | KAMATA HIDENORI |
| PURPOSE: To enhance the workability, to save labor for disposing a pile head surface, to reduce noise caused by the pile head disposal process and to prevent soil therearound from entering into concrete by vacuum-sucking excess concrete around the pile head part of an in-position placed concrete pile so as to remove the same, and by covering the pile head surface with a cover peace during curing of the concrete. CONSTITUTION: Excess concrete 3 and pile head reinforcement 4 are projected in a pile hole 2 dug by an excavator, from the head part of an in-position placed concrete pile 1 built in the hole 2. In this condition, an excess concrete part 3 which is surrounded by pile head reinforcement 4 is vacuum-sucked for removal by a vacuum hose, and then the pile head part is cured with the use of a steel cover 6. As a result, the excess concrete 3 around the outer peripheral surface of the pile head reinforcement 4 prevents soil from falling onto the pile head part from the inner peripheral wall of the pile hole 2, and the steel cover 6 prevents the falling soil from being mingled into the pile concrete part. Accordingly, the quality of the pile concrete is prevented from being deteriorated. Thereby it is possible to reduce a remaining work after completion of root-out. COPYRIGHT: (C)1995,JPO | ||||||

| The specification discloses an apparatus for harvesting vegetables such as onions, including a topping plenum and a root cutting bed. Onions are removed from the ground by a self-adjusting digger conveyor which conveys them to an elevator conveyor. The elevator conveyor rises steeply over the large diameter, wide tires which convey the apparatus through the field. From thence the onions are conveyed beneath a vacuum plenum through a first air flow zone which is baffled so that the air flow is just sufficient to raise the tops of the onions off the conveyor and then through a second air flow zone where the onions are actually lifted off the conveyor and into registry with a registering and cutting means which cuts the tops off the onions. From thence they drop onto a root cutting bed which removes the roots of the onions and conveys them to a bulk loading conveyor. Dirt and offal drawn into the vacuum fan are conveyed out of the vacuum fan housing by a continuous conveyor system. | ||||||
