Embodiment Construction
[0024] refer to figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 Make the invention. The farmland irrigation water supply device includes a pipe body 1, a joint 2 and a lock cover 3, the lower end of the pipe body 1 is fixedly installed on the farmland irrigation node pipe network, the upper end of the pipe body 1 is fixedly provided with a joint 2, and the lock cover 3 is movably arranged on the The upper end of the joint 2 is covered with a lock cover 3 to prevent non-workers from opening it at will. When water needs to be released, the lock cover 3 is opened and taken away. It is characterized in that: the cavity of the pipe body 1 There is a large slider 5 inside, and the chute 55 on the side wall of the large slider 5 is stuck on the guide rail 12 arranged axially along the inner wall of the pipe body 1 and slides up and down along the guide rail 12. The lower opening of the inner cavity is blocked and sealed...

The invention discloses a farm irrigation water feeder. The water feeder comprises a pipe body, a joint and a lock cover; the lower end of the pipe body is fixedly mounted on a farm irrigation node pipe network, the joint is fixedly arranged at the upper end of the pipe body, and the lock cover is movably arranged at the upper end of the joint; and the farm irrigation water feeder is characterized in that a large sliding block is arranged in a cavity of the pipe body, a sliding groove in the side wall of the large sliding block is clamped on a guide rail which is axially arranged along the inner wall of the pipe body and slides up and down along the guide rail, a runner is arranged in the middle portion of the large sliding block, and a small sliding block which slides up and down is arranged in the runner; and an inserting pipe at the lower portion of a water draining pipe is inserted in an upper opening of the joint, and a water outlet pipe on the water draining pipe is communicated with the inserting pipe. The farm irrigation water feeder is simple in structure and convenient to use; and when water draining is not needed, the water feeder is in the water pressure automatic closing state all the time, when water draining is needed, the water feeder can be opened only through a dedicated water draining joint, happening of water stealing or random water draining is completely eradicated, and water-saving irrigation is achieved.
Description
[0001] This application is a divisional application with application number CN201410702351.7, application date November 29, 2014, and invention name "Combined Water Supply Device for Farmland Irrigation". technical field [0002] The invention relates to an improvement of a valve for farmland irrigation, in particular to a farmland irrigation water feeder. Background technique [0003] At present, most of the farmland irrigation still continues the irrigation methods of canal water delivery and large and small flood irrigation. In order to save irrigation water, pipeline irrigation has become the main form of agricultural water-saving projects. This kind of pipeline water supply irrigation project is to lay a pipe network in the farmland, set a gate valve at each irrigation node of the pipe network, and use a water pump to supply water to the pipe network. When a certain piece of farmland needs to be irrigated, it is only necessary to open the gate valve at the corresponding ...
