Higher than the height of sill may, then restart motor 16, so that motor 16 drives the first transverse slat by threaded rod 19 and thread barrel 18
14 slide to river direction, so that square box 32 is located at the position right above river, then control first hydraulic cylinder again
20 output end elongation, by the elongation of 7 output end of hydraulic cylinder, square box 32 is sunk in river water, during this period, when first
When 24 bottom end of support plate touches river bed, the inserted link 29 on bottom end can be inserted into river bed, so that the first support plate 24 is steadily
Be located at river bed, due to the setting of two vertical bars 25, can not be moved still further below when 24 bottom end of the first support plate is contacted with river bed
When, two 25 tops of vertical bar in the first support plate 24 can be stretched out upwards from support plate 21, and then operator is warned to stop
Hydraulic cylinder 7 operates, because 24 bottom end of the first support plate is contacted with river bed, without allowing the first support plate 24 to move down again,
Operating reliability is effectively raised in this way, simultaneously because the rising of two vertical bars 25, retaining ring 27 can squeeze spring 28, and then bullet
On the elastic force meeting continuous action to the first support plate 24 of spring 28, so that the inserted link 29 of the first support plate 24 and its bottom end is firmly solid
It is scheduled on river bed, further improves the reliable and stable performance of the present apparatus.
It works after carrying out, then one, conduit of sprinkling irrigation is connected on the water outlet of electric water pump 4, then opens again above
Dynamic electricity water pump 4 operates, in this way electricity water pump 4 can pass sequentially through through-hole 33, filter screen 36, arc orifice plate 35, rectangular tube 34, stretch it is soft
Pipe 37 and water inlet pipe 5 introduce river water in sprinkling irrigation conduit, and then complete sprinkling irrigation watering work, during this period, arc cover 38
Interior blade 42 drives shaft 40 to rotate in rectangular tube 34 under the action of water flow, passes through disk 41 when shaft 40 rotates, waves
Bar 47 and axle sleeve 46 drive U-shaped bar 45 to rotate, and bar 45 U-shaped in this way will drive shaft 40 to rotate together, when turn axis 40 rotates
Its scraper plate 48 fixed above can effectively strike off the sundries such as the weeds leaf attached on filter screen 36, and then effectively prevent
The blocking of filter screen 36, effectively raises working efficiency.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
