Description

. This invention relates to sanitary cleaning of households. A known vacuum-type machine for removing, from household refuse, containing a base chassis with a cistern mounted on it with a suction hose, communicated with the cistern vacuum pump, the lower gate and the upper valve fixed on the rotary axis 1. To carry out the work of such machines, the hose is lowered into the cistern into the waste mixture, then the upper valve opening, closing the opening through which the hose connects to the internal cavity of the tank, and turns on the vacuum, sucking air, and the hose. When a vacuum appears in the cistern, which is sufficient to lift the contents of the rake, it begins to move along the hose. The disadvantage of the machine is that the time required to form a vacuum in the tank is significant and amounts to 30% of the entire cycle of the machine. The purpose of the invention is to increase the productivity of the machine by intensifying the filling of the tank. . The goal is achieved by the fact that the machine is equipped with a diaphragm pneumatic chamber, a stop fixed at the end of the rotary axis, a slide with supports installed with the possibility of longitudinal movement, and a compression spring fixed between the slide and the support, with the slide at one end connected with the diaphragm of the pneumocamera, and the other with an emphasis on the rotary axis, and the working part of the pneumatic chambers communicates with the tank cavity. Additionally, the slider is made with a wedge-shaped bevel, and the swivel axis is with an emphasis. Figure 1 shows the machine in the working position, a general view; in Fig.2, the section A-A along the upper valve in Fig.1; Fig. 3 shows the control mechanism of the upper valve; general view; figure 4 is a view of the stop. The proposed machine consists of a base chassis 1 on which a tank 2 is installed with a suction hose, with which a vacuum pump 3 is connected. In the upper part of the tank is mounted the upper valve 4, rigidly connected to axis 5 and intended to close the opening of the suction hose. The axis ends with a stop 6 designed to stop the position of the upper valve in the closed position.

A pneumatic chamber 7 is also mounted on the tank, the diaphragm of which is rigidly connected with a slide mounted on the slide supports 8. The working cavity of the pneumatic chamber communicates with the tank. The slider is pressed against the stop by a spring 10 of compression.

The machine works as follows.

Dip the hose of the machine in a mixture of calves. Using a handle attached to the axis 5 of the valve 4, rotate it together with the valve to the position / at which it closes the opening of the suction hose. In this case, the stop b is closed with a slant of the slider 9, thereby fixing the position of the valve 4.

When a vacuum i is formed in the tank, sufficient for the beginning of the movement of the horn, under the action of vacuum, the diaphragm of the chamber 7 is deformed, compressing the spring 10, moves the slider 9 to. Slider ramp exit from stop b.

At the same time, valve 4, under the action of the difference in air pressure in the suction hose and the tank, instantly opens access to the tank. There is a movement into the tank with a high velocity of air, which is in the suction pipe, and a kind of ejection effect occurs, which ensures reliable movement of the mixture of garbage through the suction hose.

The axis of the isber after the cessation of pressure differential deist is moved to the HjfJicHee position.

 After completing the filling of the tank by the barrel, take the handle with the aid of a handle to the initial position. At the same time, 13 b / abut the ram bevel / move it to the fixation with it. As a result, the / slide gate moves to its original position, closing the access tightly

in the cistern.

Due to the presence of spring 10 / operator /, adjusting its preliminary

compression / can set the amount of vacuum in the tank / at which the top valve opens automatically and the tank is filled. The spring preload or limiting vacuum in the tank is reduced depending on the properties of the mixture of garbage to be removed.

The proposed device allows to reduce the duration of the working cycle of the vacuum pump by at least 25% and to obtain /, respectively, fuel savings.
