Definitions
- the invention relates to a device for picking up elements located in one plane on the ground, for example, of a pavement comprising a fork-like scooping member, means for moving the scoop in a substantially vertical direction, . swinging means for turning the scoop about a horizontal axis and menas for attachment to a vehicle, for example, a tractor.
- Such a known device is employed for picking up paving stones.
- the device is driven to a collecting site where the scoop is emptied. After the stones are cleaned and, if necessary, the ground is heightened, the stones are reused for the pavement.
- One method consists in manually picking up the stones deposited on the storage site and placing them in a vibratory or scraping device. In this vibratory or scraping device the stones are cleaned. Picking up the stones from the storage site and depositing them in the vibratory or scraping device is a hard and monotonous job.
- a further method of removing earth or sand sticking to the stones consists in transiently actuating the control-members of the device so that by vibrating and shaking the earth or sand is removed. This method is detrimental to the bearings and the seal of the hydraulically actuated members.
- the invention has for its object to provide a device in which after the paving is picked up the stones can be cleaned in a single run.
- the stones picked up from a range of pavement are cleaned by causing the device to rotate after the flap is closed.
- the stones will tumble along and scrape one another and the loosened earth will be deposited on the site of use. Subsequently the cleaned stones can be deposited on a temporary storage site by opening the flap and by turning the scooping member.
- the fork-like scooping member preferably has a substantially semi-cylindrical shape and the flap preferably is the complement thereof.
- the flap is pivotable about a shaft arranges on the cylindrical wall of the scooping member by means of an actuating plunger arranged between the flap and the scooping member.
- a shap lock is provided.
- the inner side of the flap and the scooping member may be lined with sieving material the mesh size of which can be chosen at will.
- Precautions are required',for establishing a connection between the hydraulic control-ram rotating together with the flap and the scooping member and a stationary hydraulic pressure source.
- the hydraulic pressure source communicates through ducts with channels in a hub of the rotary shaft opening out in annular grooves in the rotary shaft of the scooping member and through ducts of the plunger- with channels in the rotary shaft opening out in the grooves of the rotary shaft.
- a fastening plate 7 is pivotally arranged with the aid of fastening beams 2 and 3 via arms 5 and 6 on a vehicle, for example, a tractor 1.
- the fastening plate 7 is coupled with a plunger 37 in a manner such that the fastening plate 7 can rotate about a shaft 8.
- To the fastening plate 7 is secured the fork-like scooping member 9.
- the scooping member has a substantially semi-cylindrical shape and holds at one end a pivotal shaft 10 for a flap 11, the shape of which is complementary to the scooping member 9.
- the flap can be caused to swing by means of the plunger 12.
- the flap can swing between an open position (fig. 1) and a closed position (fig.3). In the closed state the scooping member 9.
- a snap latch 36 which is movable between two spring-loaded locking members 13 and 14 arranged side by side.
- the paving produces a rotary effort on the scooping member 9.
- a stop 17 is provided on the fastening plate 19, at which a substantially channel-section beam 18 of the scooping member 9 is blocked.
- the plunger 12 is connected with a hydraulic pressure source provided on the tractor by means of the construction shown in fig. 6. With a stationary hub 20 are connected ducts 21 and 22 for establishing a connection with the source.
- the rotary shaft of the scooping member 9 and of the flap 11 is rotatably journalled in the bearing 24 of the hub.
- the rotary shaft 23 has two peripheral grooves 25 and 26 communicating with the ducts 21 and 22 and with longitudinal channels 27 and 28 in the rotary shaft. With the channels 27 and 28 communicate connecting ducts 29 and 30 leading the hydraulic medium to the plunger 12.
- This construction permits of coupling the simultaneously rotating plunger 12 with the hydraulic pressure source.
- a hydraulic motor 31 is provided, which drives the rotary shaft 23 through a gear wheel transmission box 32.
- the device operates as follows:
