Abstract
The utility model relates to a kind of small flow plunger pump with control tower box.The structure of the utility model includes that motor is connect with speed reducer, and crank is arranged in speed reducer two end axles；Scale-board is attached on crank；Crank is connected with bolt is connect, and pointer is preloaded on sliding block, and sliding block and oscillating bearing setting are on connection bolt；It is partially loaded cylinder body after oscillating bearing, piston rod are connected, cylinder body is packed into cylinder frame；Cylinder body is connected by check valve respectively with outlet pipe, water inlet pipe.Compared to the prior art the small flow plunger pump of the utility model, has many advantages, such as accurately control dose, reaches ideal effect of increasing production.
Description
Technical field
The utility model relates to the fertilizer application amount control devices of sprinkling irrigation equipment, especially can accurately control the small stream of dose
Measure plunger pump.
Background technique
Currently, be various small flow fertilizing pumps with the fertilizer application amount control device on irrigation sprinkler, motor connect small flow every
Membrane type fertilizing pump is connected with fertilizer spreading tank again, is to adjust by hydraulic pressure the flexible of diaphragm to change diaphragm pump volume, and then adjust and apply
Fertilizer amount, such equipment there is: precision is low, is unable to accurately control dose, and the defect of ideal effect of increasing production is not achieved.
Summary of the invention
The technical assignment of the utility model is the shortcoming for the above status, and dose can be controlled with accuracy by providing
Small flow plunger pump.
The utility model solve its technical problem be using technical solution: the small flow plunger pump of the utility model, knot
Structure includes that motor is connect with speed reducer, and speed reducer is fixed on pedestal；Crank is set in speed reducer two end axles；Scale-board is filled
Onto crank；Crank is connected with bolt is connect, and pointer is preloaded on sliding block, and sliding block and oscillating bearing setting are on connection bolt；
It is partially loaded cylinder body after oscillating bearing, piston rod are connected using itself screw thread, cylinder body is packed into cylinder frame；Cylinder frame is fixed to bottom
The both ends of seat；Cylinder body is connected by check valve respectively with outlet pipe, water inlet pipe.
The cylinder body is two.
Compared to the prior art the small flow plunger pump of the utility model, has the following characteristics that the utility model integrally leads to
Setting pointer and sliding block are crossed, the accurate control of dose may be implemented；By refining the graduation mark of scale-board, dose can be made
It is differential smaller.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawing.

Specific embodiment
Small flow plunger pump is described in detail below referring to Figure of description.
The small flow plunger pump of the utility model, structure include that motor 4 is connect with speed reducer 2, and speed reducer 2 is fixed to pedestal
On 10；Crank 13 is set in 2 two end axles of speed reducer；Scale-board 1 is attached on crank 13；Crank 13 with connect 16 phase of bolt
Even, pointer 14 is preloaded on sliding block 15, and sliding block 15 and the setting of oscillating bearing 3 are on connection bolt 16.Pointer 14 cooperates scale-board 1
It uses, adjustment 12 stroke of piston rod is slided by sliding block 15, and then adjust dose.By oscillating bearing 3, piston rod 12 using certainly
Body screw thread is partially loaded cylinder body 7 after being connected, cylinder body 7 is packed into cylinder frame 5；Cylinder frame 5 is fixed to the both ends of pedestal 10；According to left and right
Symmetrical and horizontal principle uses screw, nut difference fixed crank 13 and oscillating bearing 3 after being adjusted；Cylinder body 7 and outlet pipe 6,
Water inlet pipe 9 is connected by check valve 8 respectively.A whole set of plunger pump assembly finishes.
The cylinder body 7 is two.Use twin-tub, even if 1 cylinder body breaks down, another cylinder body can normal use,
It not will lead to work to deactivate.
When the utility model is used, water inlet pipe 9 is connected with fertilizer spreading tank, outlet pipe 6 is connected with irrigation sprinkler, gives motor
4 power supplies drive crank 13 to rotate by speed reducer 2, to drive the reciprocating motion of piston rod 12, realize the suction fertilizer note of cylinder body 7
Fertile function.
The small flow plunger pump dose of the utility model can be arbitrarily adjustable for 0 ~ 350L/H range.
The utility model is suitable for the short reel sprinkling irrigation machine across pointer irrigation sprinkler and truss structure.
