Description

The invention relates to agriculture, in particular to land reclamation, and can be used to create water retention in a temporary irrigator during operation, sprinkler machines, and can also be used to clean sediment from the bottom and walls of concrete trays.

The purpose of the invention is the expansion of functional capabilities.

FIG. 1 shows a movable movable bridge, general view; fig 2 is the same plan; in fig. 3 shows section A-A in FIG. 2; in fig. 4 - cover design, general view; in fig. 5 - section 6-B in FIG. four; in fig. b and 7 - examples of the jumper for different profiles of the flume channels.

The movable support bridge consists of a frame 1 mounted on wheels 2. To the frame 1 on metal strips 3 and bushings 4, the auger is suspended by an asterisk 6 on the shaft. The washers 7 and the studs 8 do not allow the screw 5 to move along the axis on the sleeves 4. On the metal strips 3, a cover 9 is attached, made in the form of a half pipe with end walls 10 serving as the edges of cruelty of the cover 9, as well as angles 11, which increase the overall rigidity designs.

A movable support bridge is attached, for example, to the rear hinged frame of the machine with the help of rod 12. Rotation of auger 5 with an asterisk 6 is provided from the engine's power take-off shaft through chain 13 and a gearbox (not shown), the gear ratio of which is chosen in one direction or another, it provided the necessary water pressure in the trough channel.

Mobile retaining jumper works as follows.

When moving the sprinkler from the PTO and gearbox

torque is transmitted through the chain 13 and the drive sprocket 6 to the screw 5, which, rotating in one direction or another, creates water retention in the tray necessary for normal operation of the pump of the sprinkler. The walls 10 and the lid 9 do not allow water to bypass the auger 5.

Moving up the slope of the trough channel in the operating mode, i.e. when creating a backwater for the sprinkler, the screw 5 rotates the bottom of the tray and cleans the bottom parts of the tray, the top parts of the walls, cleans the walls 10 of the cover 9, works like a scraper, while the working part of the wall 10 can be rubber or made in the form of a rigid brush.

Moving down the slope, the auger 5 rotates, throws out a jet of water, which loosens sediments (sediment) and flushes them down the slope, then along. A screw 5 passes through the loosened surface, which scraps and removes the remaining sediment particles, moving the whole mass to the end of the chute channel, from where they are removed mechanically.

Invention Formula

A movable support bridge, including a frame mounted on wheels moving along the edges of the trough channel, connected to a sprinkling machine and an interlocking device mounted on the frame, characterized in that, in order to expand its functionality, the blocking device is made an auger mounted on a drive shaft placed coaxially to the channel, while the auger is provided with a lid having end walls covering the auger around the perimeter in its upper part bounded by a line of contact w ESA with the channel walls.
