Description

Puncher with preventer

Technical field

This utility model relates to agricultural equipment field, more specifically, it relates to a kind of puncher with preventer.

Background technology

Puncher is a kind of application machinery being applied to multiple fields, such as office puncher, packaging puncher, soil puncher；Needing to carry out buried object for support posts such as electric poles, people typically use two kinds of methods: manually dig pit: manually dig pit and fill afterwards, and workload is big, inefficiency；Hole digging machine: the terrestrial positioning difficulty harder to geology, just starts to vibrate relatively violent, in-convenience in use；Therefore it is badly in need of developing a kind of work efficiency high, soil puncher easy to use.

In order to solve above-mentioned technical problem, existing equipment is transformed by people, such as China's a kind of rotary soil puncher of application utility model patent disclosed in Application No. CN201510489024.2, it is by arranging a cavity placed for localizer, cavity length is more than localizer length, and there is a manhole coordinated for latch grafting at cavity two ends；Described flap semicircular in shape, has a semi-circular recesses coordinated with rotary shaft in the middle part of straight flange, and with rotary shaft sidewall vertical welding；Described localizer one end arranges a parallel manhole coordinated for latch grafting with end face, is fixed on the cavity end of rotary shaft by latch, and with rotary shaft on the same axis.

But in place of above-mentioned technical characteristic Shortcomings, when puncher needs manual do exercises unlatching or stopping in use, when the complete needs that punch take out puncher from soil, due to puncher also at high speed rotating, bottom the puncher rotated during taking-up, human body is easily damaged by reamer, the most dangerous, needs other people to close to close, operator are taken out puncher again, waste unnecessary manpower.

Utility model content

The deficiency existed for prior art, the purpose of this utility model is to provide a kind of puncher with preventer, it is possible to resolve the complete reamer that punches cannot be automatically switched off thus operator can taken out the problem that cause personal injury.

For achieving the above object, this utility model provides following technical scheme:

A kind of puncher with preventer, including machine body, described machine body includes cavity, driving motor it is provided with in described cavity, being provided with bottom described machine body and the auger driving motor to coordinate, described auger is provided with elastic component with driving motor junction, and described motor is provided with the point driving switch contacted with auger and regulation circuit, described regulation circuit includes

Power module of voltage regulation, provides power supply for late-class circuit and controls point driving switch keying by auger；

Control module, couples detector unit, and exports control signal；

Reversely module, couples control module, coordinates control to drive motor to rotate backward with control module.

Further, described power module of voltage regulation includes transformator T, described transformator T couples bridge rectifier unit, described bridge rectifier includes diode VD1, VD2, VD3 and the VD4 being sequentially connected with clockwise, described bridge rectifier unit shunt capacitance C1, described electric capacity C1 positive pole couples audion VT colelctor electrode, and electric capacity C1 and audion VT base stage couple late-class circuit, described audion VT emitter stage couples inductance L one end, and the described inductance L other end couples point driving switch and connects late-class circuit.

Further, described control module includes that inverter ic 1 couples inverter ic 2, described inverter ic 2 input is coupled to outfan, described inverter ic 2 coupling resistance R2, resistance R2 is respectively coupled to audion VT1 and audion VT2 base stage, described audion VT1 emitter stage couples audion VT2 colelctor electrode, described audion VT1 colelctor electrode coupling resistance RP.

Further, described reverse module includes driving motor M, described driving motor M one end couples the connection end of audion VT1 Yu VT2, the other end couples the connection end of audion VT3 and audion VT4, described audion VT3 colelctor electrode coupling resistance RP2, described audion VT3 emitter stage couples audion VT4 colelctor electrode, and the base stage of described audion VT3 and audion VT4 is mutually coupled and series resistance R3, and described resistance R3 couples inverter ic 4.

The beneficial effects of the utility model are, when surface soil is punched by needs puncher, auger contacts with soil, auger extends into cavity and coordinates one end owing to driving the effect of motor self gravitation with driving motor, auger is made to contact with the point driving switch in driving motor and close point driving switch, now regulation circuit starts to drive motor rotation, when puncher takes out in soil, auger leaves and contacts with soil, elastic component produces bounce with auger, make auger away from elastic component, it is achieved that to open automatically and Guan Bi.

T is mains transformer, and VDl-VD4 is rectifier bridge, and Cz is capacitor filtering, VT is switching tube, and duty is controlled by base stage control wave U, and control wave vitriol controls from control circuit, control circuit is controlled by output voltage and consolidates, and VI is fly-wheel diode, and L is choke induction.The core of operation principle Switching Power Supply is an inverter being operated on off state, and it can be high-frequency pulse current DC current inversion.When the power is turned on, Ui inputs, and now U is less than upper limit permissible value Uam, through control circuit effect, the control wave ant of switching tube base stage is high level, and VT is in saturation conduction state, U through VT, L to C: charging, form output electric current L output, continuity over time and raise, when rising to upper limit permissible value, through control circuit effect, the control wave of switching tube base stage is low level, and V1 is in off-state.Owing to the .L that can not suddenly change of the electric current in choke induction L produces self induction voltage fly-wheel diode VD and turns on .QL because of positively biased through RL, VD afterflow, CZ electric discharge simultaneously, thus load current continuous during maintaining switching tube cut-off, but electric current, voltage are gradually reduced.When UQ drops to lower limit permissible value U0, through control circuit effect, Uk is high level, and Vr goes to saturation conduction state .C2 to be electrically charged again. now fly-wheel diode VD is reverse-biased and end, and UCT rises again.Work as U.Rise to U～time, control wave k becomes low level.The most repeatedly, circuit is in switch state, makes output voltage U0 remain between U～U0 of permission and fluctuates, and the scope of fluctuation is typically in millivolt magnitude, thus reaches the purpose of voltage stabilizing.

Compared to prior art, this utility model has the complete reamer that punches and is automatically switched off thus avoids operator are caused when taking out the advantage of personal injury.
