DIGGING APPARATUS

The utility model relates to the hydrotechnical reclamation of reservoirs by suction pumps and can be used to extract organogenic material, in particular, sapronel and other bottom sediments, as well as to obtain inert building materials (sand, gravel) and as a floating pump station for irrigation of agricultural land.

There are various devices for the operation and maintenance of reservoirs, in particular for purification from humoid formations, including sapropel 1-9. At the same time, the extracted mud layer (sapropel) as a cleaning product is subsequently used in agriculture as a valuable fertilizer.

Known, for example, dredging projectile (dredger) with a suction pipe, a mechanism for raising and lowering it, a mechanism for suction and supply of pulp, as well as a set of interchangeable dredging devices 1.

The disadvantages of such dredgers are large dimensions, low maneuverability, limited development depth.

Known dredgers, consisting of a floating body, its supporting floats, a soil collection unit (suction pipe with a pump), mounted on a frame, and a bearing hinged truss with a frame-lifting mechanism, resting on the body and, for example, by means of a guide, on two supporting floats 8. Such dredgers require large specific energy costs, and also have significant dimensions.

Known dredging projectile, taken to the proposed as a prototype for the greatest number of common essential features and the achieved technical result 4.

The dredging projectile includes a floating body in the form of a pontoon-catamaran, consisting of two rectangular sections-floats, articulated by a platform base and brackets, a buggermaster control cabin, a slurry pipe with pumping equipment for sucking and feeding pulp, a lifting and lowering mechanism for the dirt-picking branch of the slurry pipe mounted on a swivel drive frame. In the stern of the pontoon-catamaran, an additional pontoon is hung on the floats, in which a removable trellised container for collecting sapropel is placed. The slurry pipeline consists of two sections connected by a flexible hose. Based on the platform, technological equipment is placed, including a pressure apparatus

the course, made in the form of an anchor, a winch with a cable and a frame. Pumping equipment is located in the pontoon.

Such an implementation of the dredging projectile provides an increase in the depth of rise of the sapropel, as well as a reduction in energy consumption during the operation of the dredger. The implementation of an additional removable pontoon facilitates the transportation of the dredger to the place of development, however, the latter is cumbersome, has limited maneuverability when moving the working body during operation, when moving it from one reservoir to another, and the pressure stroke mechanism is not effective enough.

The task of creating a utility model was to reduce the dimensions, to ensure high maneuverability while ensuring simplicity of design and reducing energy consumption both during transportation of the dredger and during its operation.

The problem is solved by a dredging projectile, including a floating hull in the form of a platform mounted on a pontoon-catamaran, and a control cabin with a drive of the mechanism of working displacements, a slurry pipe made articulated from a soil-picking branch with a suction tip and a transport branch, a lifting and lowering mechanism of the dirt-picking branch mounted on a turn , pumping equipment for suction and pulp supply, and a pressure stroke mechanism in the form of a papillon winch with a drive, as proposed, in such a suction pump the shell of the hull platform is removably mounted on the pontoons and secured to them by means of adjusting end guides, a pair of bow and aft stern, and stop brackets mounted in the guiding zone on the contact surfaces of the platform sides and pontoons made protruding in the bow and longer than the platform 0, 8 of its size, and the pressure stroke mechanism additionally contains three papillage winches, while papillage winches are placed symmetrically on the bow and stern sections of the pontoons.

In a dredging projectile, the suction tip of the dirt branch of the slurry pipeline is conical.

The removable connection of the platform platform with the pontoons provides the convenience of transporting the dredger to the place of work, as well as its manufacturability.

The implementation of the pontoons with a length exceeding the length of the hull platform provides the dredger with a stable horizontal position on the water when lifting the swing frame with the soil branch.

Placement of papillon-driven winches with a drive symmetrically on the bow and stern sections of the pontoons provides the largest shoulder of rotation of the dredger relative to the axis of rotation, which reduces the force, respectively, energy consumption

its rotation during operation, and placing them on the surface of the pontoons practically does not create a tipping moment.

Figure 1 schematically shows a General view of the dredger, side view; figure 2 is the same, a top view.

The dredging projectile contains a floating body 1, in the form of a box-shaped platform 2, mounted on a pontoon-catamaran 3, formed of two rectangular sections of pontoons 4 connected by a platform 2, on which a control wheelhouse 5 with a drive of the mechanism of working movements (not shown) is placed. The pontoons 4 are filled with a length greater than the length of the platform 2 by 0,, 8 of its size, installed flush with the platform in the stern and protrudes in the bow. The control cockpit 5 in the aft part has a superstructure 6, under which in the hold of the platform 2 there is pumping equipment 7 with electric drive 8 for suction and supply of pulp by means of a slurry pipe 9 made from the soil branch 10 with the suction conical tip 11 and the transport branch 12. Soil branch 10 mounted on a rotary frame 13, pivotally mounted to the side of the platform 2 and equipped with a lifting and lowering mechanism 14, for example, in the form of a winch. Transport branch 12 is located in superstructure 6 in its hold. Four papillage winches 15 with electric drives symmetrically mounted on the pontoons 4, at the stern and on the bow, constituting the mechanism of the pressure stroke of the dredger. The platform 2 is removably mounted on the pontoons 4 and secured to them by means of adjusting end guides, a pair of 16 bow and a pair of 17 aft, as well as thrust brackets 18, 19 mounted in the area of the guides 16 and 17, respectively, on the contact surfaces of the sides of the platform 2 and pontoons 4.

The dredger works as follows. The dredger in a collapsible state is delivered to a reservoir, collected (assembled). After moving to the development site, the suction tip AND of the soil intake branch of the slurry pipe 9 is buried into the sapropel layer, by means of the frame 13 and mechanism 14, and the anchors of the papillon winches 15. Next, the pumping equipment 7 is turned on, and the process of collecting the pulp and moving it along the slurry pipe 9 begins. In this case, the development of soil (organogenic material, sapropel, and other bottom sediments) is carried out according to a fan pattern, i.e. in an arc from left to right and from right to left. This is achieved due to the forced rotation of the dredger body, carried out by means of papilage winches 15 from the drive of the working displacement mechanism, which also provides the possibility of moving the body forward.

operation, can be made of accessible materials with the use of nodes mastered by the industry and computer parts, does not require special equipment and sophisticated equipment.

The dredger will allow efficiently and with minimal costs to clean both inland water bodies and coastal marine zones, improve the environmental situation, get cheap raw materials for processing it into secondary resources; reclaim a construction site or shore protection zone.

Thus, the use of the proposed dredger will reduce energy consumption, primarily for the extraction and removal of sapropel, simplifies the design, and thereby reduces its cost, as well as the cost of the products obtained.
