Description

The utility model relates to the field of reclamation engineering and can be used to clean the fixed bottom of the channels of the drainage reclamation network from sediment, silting, vegetation and debris, as well as to clean the bottom of the channels of the irrigation reclamation network.

Known devices used to clean the bottom and slopes of the channels:

Author's certificate SU No. 1452900 Sewer cleaner. The invention relates to the mechanization of irrigation and drainage works and can be used for periodic cleaning of the bottom and slopes of canals from sediment and vegetation. The purpose of the invention is to improve the performance of the canal cleaner by reducing the cycle time. The sewer cleaner has a wheeled base machine with a frame. On the latter, an arrow is articulated, articulated with a handle having a working body. An overrunning clutch is installed on the axis of attachment of the boom to the frame, to which the input shaft of the bevel gear is connected.

Author's certificate SU 1717737 A1 Sewer cleaner. The invention relates to earth-moving machines and is intended for cleaning channels. The purpose of the invention is to simplify the control of the channel cleaner by synchronizing the control of the counterweight and the support element oppositely located on the lever. The sewer cleaner has an additional element. One end of the element is connected to the counterweight, and the other is pivotally connected to the frame.

Author's certificate SU 927915 A1 Sewer cleaner. The invention relates to earth-moving machines, and in particular to the designs of machines for the production of earthworks for cleaning sediment from open channels. Known channel cleaner, including the base machine, boom and working body. The disadvantage of this device is the heavy load on the base machine from the working equipment. Closest to the proposed one is a canal cleaner, including a tractor with a working body movably mounted on it, in the upper part of the frame of which a longitudinal groove is made, having guides for rollers mounted on a support axle with the possibility of transverse movement of the working body. The disadvantage of a canal cleaner with a cantilever hitch of the working body is that the base machine is not unloaded from the overturning moment created by the attached equipment. As a result, there is an unfavorable distribution of specific pressures on the supporting surfaces of the base tractor propellers, with the greatest loads falling on the propeller located closer to the edge of the processed channel, which can lead to stability loss and slope destruction. The purpose of the invention is to increase cross-country ability by evenly distributing loads on the tractor propellers. The goal is achieved by the fact that in the canal cleaner, which includes a tractor containing a body with front and rear movers, a hinge frame with a working body and an outrigger with a counterweight, the hinge frame is equipped with a turntable, which is mounted on the tractor body between the front and rear movers and is installed with the possibility coverage of the body and swing in the vertical plane.

The closest to the utility model in terms of essential features is the working body for cleaning the bottom of the channels copyright certificate SU No. 1452900 Canal cleaner. The working equipment is installed on a wheeled base machine with a frame. On the latter, an arrow is articulated, articulated with a handle having a working body. An overrunning clutch is installed on the axis of attachment of the boom to the frame, to which the input shaft of the bevel gear is connected.

The main disadvantage of the known technical solution is that the device does not clean the fixed bottom of the meliorative canals. The use of cross-cutting canal cleaners for cleaning the fixed bottom leads to their destruction.

From the analysis of known technical solutions, it was revealed that the technical problem in this area is the need to create a working body that cleans the fixed bottom from sediment, silting and vegetation without destroying the fastening structures.

The technical result of the proposed solution is to ensure high-quality cleaning of the fixed bottom of the channel from sediment, silting, vegetation, herbage, wood inclusions and debris without destroying the fascine, plank or other bottom fastening structures.

To solve a technical problem and achieve the claimed technical result in a working body for cleaning the bottom of reclamation canals, including an arrow mounted on a frame, a handle with a bucket, which is made of two parts, the upper part being made in the form of a box pivotally connected to the handle, and the lower the part is formed in the form of two cutting knives pivotally connected to the upper part, in addition, the device is equipped with short-stroke hydraulic cylinders, which provide control of the cutting knives by means of a system of rods and pushers. The working body is made with the possibility of its lateral attachment to the intermittent canal cleaner moving positionally along the channel berm, while the bucket does not perform the working movement characteristic of transverse digging equipment, but allows unloading the contents of the working body strictly onto the channel berm.

The device is illustrated by drawings.

In FIG. 1 shows the general scheme of the working body;

in fig. 2 - general view of the working body top view;

in fig. 3 - general view of the working body in isometry.

The working body for cleaning the fixed bottom of the reclamation canals, connected to the lateral mounting arm of the reclamation canal cleaner, contains the upper part 1 in the form of a box, the lower part 2 in the form of two cutting knives pivotally connected to the upper part, the handle 3, made in the form of a rectangular tube, cylindrical axles 4 for connecting the lower part with the upper, rods 5 and pushers 6, axle 7 for connecting the bucket with the handle, hydraulic cylinder 8 for ensuring the rotation and fixation of the working body - bucket, axles 9 and 10 for connecting the hydraulic cylinder with the bucket and the handle, short-stroke hydraulic cylinders 11 to control the cutting blades.

The proposed bucket working body is a replaceable device for the working equipment of the canal cleaner. The working equipment of the canal cleaner includes the main frame, the turning mechanism and the boom (not shown in the drawing).

The device works as follows.

The handle 3 with the bucket by means of cylindrical axes through the lugs is pivotally connected to the side mounting arm of the reclamation canal cleaner.

With the help of an arrow, the handle 3 with a bucket is lowered to the bottom of the fixed channel, where there are wet sediments, silting, vegetation, herbage and woody inclusions. When this cutting blades 2 with the help of two hydraulic cylinders 11 are directed vertically downwards. Further, the cutting knives are introduced into the soil, then with the help of hydraulic cylinders they are closed, developing the soil, sediments and filling the bucket. After filling with soil and sediments, the bucket is lifted with the help of an arrow and a handle, rotated to the place of unloading on the berm, the cutting knives are opened with the help of hydraulic cylinders and the bucket is unloaded. Next, the working equipment is rotated back into the channel. After working out the bottom, the channel cleaner moves to the next position, the cycle repeats. According to the mode of operation, the utility model is considered as a device of periodic action.

Compared with the prototype, the proposed device will allow high-quality and high-performance cleaning of the fixed bottom of reclamation canals, where the use of cross-digging canal cleaners is impossible.
