Description

Mobile drip irrigation water supply machine

technical field

The utility model belongs to water-saving irrigation machinery, in particular to a mobile drip irrigation water supply machine.

Background technique

Water-saving irrigation drip irrigation has high requirements on water quality, and the irrigation water should be filtered in advance to prevent the drip irrigation belt from clogging. At present, the mobile filter structure used in China is that a sand filter, a water pump and a power machine are installed on a frame with wheels. The filter is easy to move and highly maneuverable. However, the filter is a sand filter, which has a large volume and low filtration efficiency. It is troublesome to clean the impurities and dirt in the filter. It must be shut down and disassembled for cleaning, which is labor-intensive and time-consuming.

Contents of the invention

The purpose of this utility model is to provide a mobile drip irrigation water supply machine, which is not only convenient to move and has strong maneuverability, but also has low operating pressure, small resistance, high filtration efficiency, and it is very convenient to clean impurities and dirt in the filter without stopping. For the filtering of irrigation water, the cleaning of the filter can be completed under the condition of normal irrigation water supply.

The purpose of this utility model is achieved in this way: a mobile drip irrigation water supply machine, including a water pump driven by a power machine and a filter tank connected to the water pump through a pipeline on the traction trailer frame, the water supply pipe connected to the outlet of the water pump is equipped with respectively The parallel branch pipes of the valves are respectively connected to at least two screen filter tanks, the outlet pipes respectively arranged on the branch pipes are respectively connected to the sewage pipes through the backwash valves, and the outlet pipes of the screen filter tanks are connected to the drain pipes.

The power machine, the water pump and the mesh filter tank of the utility model are all installed on the traction trailer frame, which is convenient to move and has strong maneuverability. The filter mesh of the mesh filter tank has high filtration precision, which improves the filtration efficiency. When the utility model works normally, all the valves on the branch pipes at the water inlet of the parallel net filter tank are in the open state, and the backwash valves on the outlet pipes connected under the branch pipes are in the closed state, and the water flows into the filter, and the sewage in the water The food is blocked by the filter screen, and the filtered water flows into the field for irrigation and fertilization through the drainage pipe. The utility model has low operating pressure, small resistance and high filtration efficiency. When it is necessary to clean the dirt filtered by the filter screen in the filter tank, it is only necessary to clean one of the parallel network filter tanks working at the same time, and the other screen filter tanks work as usual. The cleaning process is as follows: first open the backwash valve on the outlet pipe under the water supply pipe branch of the filter tank to be cleaned, and then close the water inlet valve on the water supply pipe branch of the filter tank. At this time, the water flow direction of the filter tank Change occurs, the water flow enters the filter tank from the outlet pipe at the bottom of the filter tank and passes through the filter screen in reverse, washes away the dirt on the filter screen, and enters the sewage pipe to discharge the system. The utility model is very convenient for cleaning the dirt in the filter tank, without stopping the filtering work of irrigation water, and the cleaning work of the filter can be completed under the condition of normal irrigation water supply.

FIG. 3 is a schematic top view of the structure of FIG. 1 .

Detailed ways

A mobile drip irrigation water supply machine, as shown in Fig. 1, Fig. 2 and Fig. 3, includes a water pump 8 driven by a power machine and a filter tank 6 connected by a pipeline on a traction trailer frame 1. Height-adjustable legs 2 are arranged on the front and rear sides of the traction trailer frame 1, and the power engine is a diesel engine 11 or an electric motor. The water supply pipe 5 connected to the outlet of the water pump 8 is respectively connected to the water inlets of at least two screen filter tanks 6 through parallel branch pipes 15 equipped with valves 7, and the number of screen filter tanks 6 is 2-6. A valve 18 is installed on the water supply pipe 5 . The outlet pipes 16 respectively arranged on the branch pipes 15 are respectively connected to the sewage pipes 4 through the backwash valves 17 , and the outlet pipes of the mesh filter tank 6 are connected to the drain pipes 3 . On the traction trailer frame 1, a fertilization tank 12 with a feeding port is also installed, and the fertilization tank 12 is provided with a water inlet and a water outlet, and the water outlet pipe 14 installed at the water outlet is connected with the water inlet pipe of the water pump 8 by a valve 13, The connecting pipe 9 installed at its water inlet is connected with the drain pipe 3 through a valve 10 . When fertilization is needed, chemical fertilizers are added from the feeding port of fertilization tank 12. When water pump 8 was working, the valve on the water inlet and outlet of fertilization tank 12 was opened, and the negative pressure generated in the water inlet pipe of water pump 8 will remove the liquid in the fertilization tank 12. The fertilizer suction water pump 8 is input into the filtering water supply system of the present utility model, and the spraying and drip irrigation system entering the field along with the water supply flow realizes field irrigation and fertilization.
