The panel is fixed on the outside cover which is arranged on the base of the cotton baling press by the fixed bases at the two ends of the outside cover. And the two body protection devices are symmetrically arranged on the base of the baling press. The control circuit is formed by a plurality of pairs of ultrasonic transmitters and receivers which are fixed on the panel with equal distance and a singlechip circuit, the output of which is connected with the power relay of the baling press, and the installation distance on the panel of a plurality of pairs of ultrasonic transmitters and receivers is more than or equal to the diameter of the rotating box of the baling press. When the baling press is working, if anyone enters the working area, the ultrasonic wave can be reflected back, and after the receiver receives the reflective wave, the signal is sent to the singlechip and adjusted by thereof. If the person enters the setting protected area, the microcontroller outputs control signal and cuts off the power supply of the baling press, avoiding body damage accident.

Description

The protecting human body device that is used for cotton press
Technical field
The utility model belongs to the cotton processing machinery field, relates to a kind of protecting human body device that is used for cotton press.
Technical background
At present, domestic cotton processing factory generally adopts changes box cotton press, promptly adopts a case that the gined cotton that processes is carried out precompressed, and Rotate 180 ° behind the precompressed constant weight carries out roof pressure again and becomes bag, and after roof pressure became bag, chamber door was opened, and manually ties up then.In operation, owing to reasons such as artificial or mechanical disorders, when personnel did not leave the control panel, the packer misoperation often caused accidents such as personal injury.In addition, because the electronic commentaries on classics case of packer, rotating speed is fast, and leaving to start when changeing the case scope the people changes case, or has the people to be strayed into rotating range when changeing case, will cause serious human casualty accident.
The model utility content
The purpose of this utility model is to provide a kind of protecting human body device that is used for cotton press, and this protective gear is contained on the packer, can avoid cotton press to change the interior personal injury accident of case rotating range.
The protecting human body device that is used for cotton press provided by the utility model adopts following technological scheme: this protecting human body device is made up of panel, outer cover, fixed base and control circuit, fixed base is arranged on the two ends of outer cover, panel is fixed on the outer cover, outer cover is installed on the base of cotton press by the fixed base at its two ends, the protecting human body device is two, and symmetry is installed in the both sides of packer base; Described control circuit by with uniformly-spaced, the N that is fixed on the panel forms to (N 〉=2) ultrasonic transmitter and ultrasonic receiver with the single chip circuit that they join, the output of single chip circuit and the power supply relay of cotton press join, be fixed on N on the panel to ultrasonic transmitter and ultrasonic receiver the mounting distance on panel greater than, equal the diameter that packer changes case.
Its working principle of protecting human body device that is used for cotton press provided by the utility model is as follows: when connecting the packer power supply, connect the power supply of control circuit in the protecting human body device, at this moment, single chip circuit in the control circuit is to the N that uniformly-spaced is fixed on the panel N ultrasonic transmitter in (N 〉=2) ultrasonic transmitter and the ultrasonic receiver being sent signal, this N ultrasonic transmitter work, send ultrasound to panel the place ahead, because the protecting human body device is two, symmetry is installed in the both sides of packer base; Enter the working zone on people's packer both sides this moment if any the people, will return ultrasonic reflections on the panel on chartered plane base both sides, after distance is advanced the people working area nearest ultrasonic receiver of human body and is received this ultrasonic signal that is reflected, send signal to single-chip microcomputer immediately, judge according to the signal of sending here by single-chip microcomputer, entered the protected zone that single-chip microcomputer sets as messenger, single-chip microcomputer is then exported control signal to the power supply relay of the cotton press that joins with it, cut off the power supply of packer, avoid taking place human injury's accident; Do not enter the protected zone that single-chip microcomputer sets as messenger, the signal that single-chip microcomputer sends makes the power supply relay of cotton press keep former working state, the packer proper functioning.Since be fixed on N on the panel to ultrasonic transmitter and ultrasonic receiver the mounting distance on panel greater than, equal the diameter of packer commentaries on classics case; this just changes the place ahead of case at the both sides of packer protecting human body device; two invisible warning lines have been formed symmetrically; as long as someone has surmounted them; enter in the zone of protection that single-chip microcomputer sets; single-chip microcomputer sends control signal to the cotton press power supply relay that joins with it immediately; cut off the power supply of packer, avoid cotton press to change the interior personal injury accident that takes place of rotating range of case.
The protecting human body device that is used for cotton press provided by the utility model; simple in structure; easy for installation; owing to adopted ultrasonic technology and singlechip technology; and adopted and be subjected to monolithic processor controlled multiplex ultrasonic transmitter and receiver; control very sensitive; no matter be that personnel do not leave the control panel; or packer has the people to be strayed into rotating range when changeing case; this protecting human body device all can cut off the working power of packer immediately; avoid consequent human casualty accident, this protecting human body device not only is applicable to cotton press, and is applicable to the equipment that various needs are protected within the specific limits.
