Abstract
The invention relates to an electronic control pipe-clamping flow valve, and belongs to the technical field of agriculture and forestry facilities. The valve comprises a rod-type first pipe clamp and a rod-type second pipe clamp which are respectively positioned on two sides of a fluid conveying hose and are opposite to chucks, wherein one end of the first pipe clamp, which is away from the corresponding chuck, is hinged to a stander, and the other end of the first pipe clamp is hinged with a connection frame rod through a connection rod to form a four-connection-rod mechanism; one end of the second pipe clamp, which is away from the corresponding chuck, is hinged to the stander; the second pipe clamp and the connection frame rod respectively form cam pairs with two sides of a cam driven by a motor; the cam is provided with a contour consisting of two symmetric curves; when the pole diameter of the cam, which is contacted with the second pipe clamp and the connection frame rod, is enlarged, a distance between the two opposite chucks is shortened; and when the pole diameter of the cam, which is contacted with the second pipe clamp and the connection frame rod, is reduced, the distance between the two chucks is enlarged. The electronic control pipe-clamping flow valve is simple in mechanism and easy to implement; the two chucks symmetrically clamp the hose, so that the flow can be adjusted steadily; and therefore, precise pesticide application can be facilitated.
Description
Technical field
The present invention relates to a kind of flow control valve, especially a kind of electronic control clamp Flow valve that is applied to plant protection, belong to agricultural facility technology field.
Background technique
Accuracy pesticide applying can be avoided the waste of agricultural chemicals, reduce the harmful effect to environment as far as possible, is therefore advocated energetically.Yet the device for administration of drugs such as existing agricultural atomizer, atomizing sprayer all lack the accurate control device of flow, therefore are difficult to meet the requirement of accuracy pesticide applying.
Although flow control device kind of the prior art is a lot, complex structure not only, and be not suitable for controlling the fluid flow in flexible pipe, therefore can't be applied to agricultural spraying facility.
Summary of the invention
The object of the invention is to: propose a kind of being suitable for and stable control fluid flow and electronic control clamp Flow valve simple in structure in flexible pipe, thereby meet the accuracy pesticide applying user demand of agricultural spraying facility.
In order to reach above purpose, electronic control clamp Flow valve of the present invention comprises and lays respectively at fluid-conveying hose both sides and relative shaft-like the first tube gripper and the second tube gripper of chuck; Described the first tube gripper is hinged on frame away from an end of chuck, and the other end is hinged by connecting rod and side link, forms quadratic crank mechanism; Described the second tube gripper is hinged on frame away from an end of chuck; Described the second tube gripper and side link form the cam pair with the cam both sides of driven by motor respectively, and described cam has the profile that two sections symmetrical curves form; When described cam and described the second tube gripper and Ji footpath, side link contacting point become large, described two relative chuck pitch smaller; When described cam and described the second tube gripper and Ji footpath, side link contacting point diminish, described two chuck spacings become large.
Like this, as long as the corner of control on demand motor can pass through the spacing of cam adjustment two chucks, thereby change the sectional area that is held flexible pipe, to reach the purpose of flow control.The present invention not only mechanism is simple, is easy to realize, and also the symmetrical clamping of two chucks flexible pipe, can make the adjusting of flow very steady, therefore be conducive to realize accuracy pesticide applying.
The present invention further improves, and also comprises the flow transducer be placed in fluid delivery pipeline, and the signal output part of described flow transducer connects the controlled end of described motor by control circuit.Therefore, can, according to the difference of measured discharge and required flow, realize the closed loop control of flow.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
The structural representation that Fig. 1 is one embodiment of the invention.
The control circuit schematic diagram that Fig. 2 is Fig. 1 embodiment.
Embodiment
Embodiment one
The electronic control clamp Flow valve of the present embodiment as shown in Figure 1, comprises that laying respectively at fluid-conveying hose 3(can be silicone tube, rubber pipe, pitch tube, plastic tube etc.) both sides and relative shaft-like the first tube gripper 1 and the second tube gripper 2 of chuck.Two chucks are relative semicircle.The first tube gripper 1 is hinged on frame away from an end of chuck, and the other end is hinged by connecting rod 4 and side link 5, forms parallel four-bar linkage.The second tube gripper 2 is hinged on frame away from an end of chuck.The second tube gripper 2 and side link 5 are contained in oneself roller with it and the cam 6 both sides formation cam pairs of motor 7 drives by hinge respectively.Cam 6 has the profile that two sections symmetrical curves form.When cam 6 and the second tube gripper 2 and side link 5 Ji footpaths, contacting point are become when large gradually by little, the pitch smaller of two relative chucks, thus can dwindle the actual internal area of fluid-conveying hose 3, flow is diminished thereupon; When cam 6 and the second tube gripper 2 and side link 5 Ji footpaths, contacting point, when diminishing greatly gradually, it is large that two chuck spacings become, thereby can increase the actual internal area of fluid-conveying hose 3, makes flow become large thereupon.Be mounted with flow transducer 8 in fluid delivery pipeline, the signal output part of this flow transducer connects the controlled end of motor 7 by control circuit 9.
The concrete formation of control circuit 9 as shown in Figure 2, comprise micro-chip processor U3, drive chip U2 and voltage stabilizing chip U1, wherein micro-chip processor U3 has the digital signal mouth---com port and analogue signal mouth---one of DDZIII mouth, can select as one sees fit to be connected with corresponding flow sensor signal output terminal, two kinds of signals can independently be used, and also can use simultaneously.The control signal output terminal of micro-chip processor U3 is by driving chip U2 to connect the controlled end of motor.U1 is the control circuit power supply.
After micro-chip processor collects the signal of flow transducer, according to analyzing judgement, determine turning to and amplitude of motor, corresponding control signal is outputed to drive motor rotation after motor-drive circuit.Can realize closed loop control like this, form the Flow valve that control accuracy is higher, stability is stronger.
In addition to the implementation, the present invention can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
