Abstract
The utility model relates to a constant pressure medical kit mixing apparatus. The apparatus consists of a water tank (1), a flow meter (2), a medical kit (3), a switch valve (4), a micro air pump (5), a pressure sensor (6), a solution mixing chamber (7), a solution pump (8), a nozzle (9), and a constant pressure controller (10). The medical kit (3) is all sealed, communicated with the above micro air pump (5) through a pipe and communicated with the underneath switch valve (4) for medical solution to outflow, and is additionally connected with the pressure sensor (6) for detecting the pressure intensity of the solution in the kit. Water in the water tank (1) can flow into the solution mixing chamber (7) through the flow meter (2). Medicine in the medical kit (3) goes into the solution mixing chamber (7) through the switch valve (4) and is mixed with the water. The mixed solution in the solution mixing chamber (7) is sprayed out through the nozzle (9) which is driven by the solution pump (8). The pressure can be detected by the pressure sensor (6), and the constant pressure controller (10) controls the micro air pump (5) to elevate the pressure, which ensures a constant pressure in the medical kit (3). Thus the medical solution flow cannot be affected by pressure.
Description
Technical field
This utility model relates to fields such as machinery, sensing technology, electronic technology.
Technical background
Mix medicine formula variable rate spray in the agricultural in real time and belong to the spraying new technology, the agricultural chemicals flow-control belongs to technological difficulties, and this medicament-mixing device of the utility model design can solve the problem of medicinal liquid flow control.
Summary of the invention
The utility model relates to a kind of constant voltage medicine-chest medicament-mixing device, and this device comprises water tank (1), flowmeter (2), medicine-chest (3), switch valve (4), micro air pump (5), pressure sensor (6), mixes liquid chamber (7), liquid pump (8), nozzle (9) and constant-voltage controller (10); Water tank (1) is connected to flowmeter (2), is connected to mixed liquid chamber (7); Medicine-chest (3) is hermetically sealed, connects micro air pump (5) through pipeline above, connects switch valve (4) and pressure sensor (6) below, and switch valve (4) is connected to mixed liquid chamber (7); The mixed liquor that mixes in the liquid chamber (7) send nozzle (9) ejection through liquid pump (8) driving.

The new beneficial effect of this practicality is the soup that pressure stability is provided for variable rate spray control.
Description of drawings
Fig. 1 is the medicament-mixing device structure chart, and Fig. 2 is the constant-voltage controller schematic diagram
Among Fig. 1 and Fig. 2,1 is that water tank, 2 is that flowmeter, 3 is that medicine-chest, 4 is that switch valve, 5 is that micro air pump, 6 is that pressure sensor, 7 is that mixed liquid chamber, 8 is that liquid pump, 9 is that nozzle, 10 is a constant-voltage controller.
Specific embodiments
In the present embodiment, the following connection traffic meter (2) of water tank (1), flowmeter (2) is connected to mixed liquid chamber (7); Be connected to micro air pump (5) above the medicine-chest (3), medicine-chest has two openings below (3), and first opening is connected to switch valve (4); Second opening is connected to pressure sensor (6), and switch valve (4) is connected to mixed liquid chamber (7), and the right of mixing liquid chamber (7) connects liquid pump (8); The output of liquid pump (8) connects nozzle (9); The medicine of the water of water tank (1) lining and liquid case (3) lining mixes at mixed liquid chamber (7), when liquid pump (8) is worked, drives the liquid that mixes in the liquid chamber (7) and is sprayed by nozzle (9).
In the present embodiment, medicine-chest (3) is totally enclosed liquid case, is processed by iron sheet, processes squarely, can bear two atmospheric pressure with upward pressure.
In the present embodiment, pressure sensor (6) adopts the 26PCCFA6D differential pressure pick-up, and it bears pressure nominal value is an atmospheric pressure.
In the present embodiment, it is AJK-B2701 that micro air pump adopts model, adopts the power supply of direct current 6V power supply.
In the present embodiment; The signal that constant-voltage controller among Fig. 2 (10) adopts the INA128 chip that pressure sensor is sent here amplifies; Regulate R1 and make multiplication factor be set at 50 times, comparator adopts the LM358 chip, and its in-phase end current potential is regulated by resistance R 2; Voltage range is 0 ~ 5V, and R2 arrives certain value with voltage-regulation as required.When the medicine-chest internal pressure was not enough, the voltage of pressure sensor (6) output was less, and the voltage of INA128 output is less than comparative voltage, and comparator is exported high level; Triode Q1 conducting, relay work, micro air pump (5) machine operation; Give medicine-chest (3) pressurization, when medicine-chest (3) when pressure is enough, the voltage of pressure sensor (6) output is bigger; The voltage of INA128 output is higher than comparative voltage, the comparator output low level, and micro air pump (5) stops pressurization.When liquid flowed out, micro air pump (5) was worked under the control action of constant-voltage controller (10).
