Description
l~is inven-tion relates to a system for spraying an insecticide or the like inside an enclosure, such as a barn.
More particularly, the invention is concerned with an arrangement which permits an automatic spraying of an insecticide or the ~ike in a barn, for a given period and at a time of the day when workers are not inside the barn, such as at night.
It is well known that insects, more especially those which are found in barns can be extremely harmful to animals. mis is the reason why it is essential to have a program for spraying insecticides in the environment where the animalq spend an important part of their time. It is also known that certain insecticides may be harmful to the humans while being acceptable for the animals. Therefore, the application o-f an insecticide inside a barn often implies precautionary measures, such as masks or the like. PreEerably it would be desirable to introduce the insecticide in the atmosphere of a barn while the workers are not there. Of course, this is not simple, and to this date it is not believed that this can be done very easily.
However, certain types of insecticides can be applied in the presence of animals, such as some insecticides based on pyrethrum and water. The system accordin~ to the invention is specially designed to improve the e-Eficiency and the ease of application of these types of insecticides.
It is an object of the present invention to provide a system which enables to successfully apply an insecticide in an environment where animals spend an important part of their time.
It is another object of the present invention to ~7_ provide an arrangement which enables to apply the insecticides without risking that a human being would inhale possibly harmful vapours.
It is another object of the invention to provide an automatic system which makes it possible to automatically introduce a spray o~ insecticide inside a barn at a given time of the day and for a predetermined period.
In accordance with the invention, there is provided a system for spraying an insecticide or the like inside an enclosure which comprises in combination:
a) a spray applicator b) rotatable means' c) means -for mounting the spray applicator on the rotatable means so as to enable the spray applicator to direct a spray of insecticide or the like around the axis of the rotatable means following rotation of the spray applicator, d) means for feeding an insecticide or the like to the spray applicator, e) control means enabling to feed the insecticide or the like to the spray applicator while the latter produces a rotary spray inside the enclosure.
; In accordance with a preferred embodiment of the invention, the control means are automatic so as to produce a rotary spray of insecticide for a yiven period of time.
Preferably, the automatic control means are associated with means enabling the rotary spray to be applied at a given time of the day.
In accordance with another embodiment o~ the invention, the system comprises a container to contain the insecticide or the like and a duct connecting the container to said spray applicator. A valve is preferably associated wi th the duct to enable rotation of the spray applicator without twisting the duct.
In accordance with another embodiment of the invention, there is provided mixing means to mix said insecticide or the like in said container prior to feeding the same to the spray applicator.
The invention is illustrated without limitation thereto, by means of the annexed drawings in which:
FIGURE 1 is a view showing various parts of a system according to the invention, FIGURE 2 is a view of the electrical control which is used to operate a system according to the invention' FIGURE 3 is a perspective view of the spray applicator mounted on a rotary table, FIGURE 4 is a side view showing the combination illustrated in Figure 3 mounted on a ceiling, FIGURE 5 is a cross-section view of the valve between the rotary spray applicator and an insecticide container;
FIGI~E 6 is a view of the insecticide container partially cut away to show the mixer, and FIGURE 7 is a view showing the mixer and the motor.
With reference to the drawings, it will be seen that the system according to the invention basically comprises a spray applicator 1, a rotary table 3 on which the spray applicator 1 is mounted in known manner, an insecti.cide container 5 as well as a control panel 7.
The spray applicator 1 can be of any type which is well known to those skilled in the art~ In the system which has been illustrated, the spray applicator is one which is known by the name MICRO-3 which is sold by Fogmate. One model has been described in U.S. Patent ~o. 2,705,171.
Basically, it is a combination of a venturi tube and some whirling means to produce the discharge of a fog. In essence, air is forced to the spray applicator in the direction indicated by the arrows a and introduces a mist as shown by the arrows b.
The spray applicator 1 is mounted in known manner ~; by means of a bracket 9 on a rotary table 3. Such a rotary table is also of standard construction and one which is known by the trade mark ~ MORE can be used. It is merely sufficient to electrically connect the two components 1 and 3 together by means of the electrical connection 11. It will ~0 therefore be seen that when the power supply is on, the rotary table 3 will cause a corresponding rotation of the spray applicator 1.
m e system according to the invention comprises a container 13 which is filled with an insecticide 15 and is provided with a mixer 17. The idea is that, in operation, the system will always produce a mist or a fog containing an insecticide at a concentration which is substantially constant.
This is the reason why the mixer 17 has to be in operation when the system functions. To operate the mixer 17, there is a motor 18 which is also of standard construction.
The contalner 13 is connected to the spray applicator 1 by means of a duct 19, valve 21 and duct 23.
In addition, there may be provided along the duct 19, a three-way valve 24 to connect the spray applicator to the insecticide 15 or to a germicide not shown or to a disinfectant not shown.
It will be noted that the duct 19 has a portion 25 which extends near the bottom of the container 13. m e downwardly extending portion 25 is terminated by a conical member 27 through which the liquid insecticide 15 penetrates into the duct 25, 19.
It was mentioned above that the insecticide which is injected into the atmosphere of, for example, a barn should have a concentrati.on which is just about constantO For - this purpose, there is provided a mixer 17 which will now be described.
The specific construction of the mixer 17 has been motivated ~y the fact that a convenient container is one having an opening 29 on one side as shown in Figure 6 and the fact that to make sure that there is a good mixing of the insecticide in the diluent, the latter should preferably plunge in a diagonal fashion into the liquid. To arrive at this, the mixer 17 is formed of a curving elongated guide 31 which is shaped as shown in Figure 6 and 7 to plunge into the container 13. As shown, the curving elongated guide 31 extends through cap 33 inside motor enclosure 35.
A flexible shaft 37 which is long enough to extend near the bottom of the container 13 is connected in known manner to the motor 18. Along the flexible shaft there are provided a plurality of groups of flexible strips 41. In the example illustrated in Figure 6, there are four groups of flexible strips 41. These strips can be made by starting with a length o-f plastic tube and slitting the latter longitudinally along a certain length of the plastic tube and all around the latter until six or more slits 41 are produced. Each mixing unit therefore comprises a number of flexible strips 41 and a length of plastic tube 45 from which the flexible stxips depend.
A mixing unit is then assembled on the shaft 37 by merely sliding the tubular portion 41 in the various positions illustrated by the four units shown in Figure 6~
This particular type of mixer has been designed because it has been found suitable to use a standard container such as container 13 for storing the insecticide. This container has a singl~ opening 43 which is not wide enough to accommodate a large mixer. It will be seen that the flexible strips 41 will easily be bent one way or the other whether the mixer is being inserted into the container 13 or is being removed therefrom.
It was mentioned above that the spray applicator 1 should rotate during the application of an insecticide. In order to prevent the twisting of the insecticide duct 19, there has been provided a special valve 21 which will now be described with reference to FIGURE 5.
me valve 21 comprises a nipple 47 which has a narrow portion ~9 followed by a wide portion 51 thus defining a shoulder 53. Referring back to the spray applicator 1, the latter has a holding plate 55 fixed thereto having a free protruding end 57. In the protruding end 57 of the holding plate 55, there is an opening 59 for receiving the narrow portion 49 of the nipp:Le 47. In this position, it will be noted that the narrow portion 49 extends through the opening 59 until the portion 57 of the holding plate rests against the shoulder 53. The holding plate should be fixed, by any known means, to the shoulder 53.
The second duct 23 engages the end 61 of the narrow portion 49 of the nipple 47.
The valve also comprises a tube 63 which is dimensioned to fit into the narrow portion ~9 of the nipple 47. The tube has a flange 65 near the upper end thereof, which is received into the narrow portion of the nipple. A
spring 67 which is engaged by the wide portion 51 of the nipple engages the flange in the direction of the arrows c, as shown in Figure 5 of the drawings. In this manner, the flange 65 rotatably abuts the bottom of the wide portion 51 of the nipple. The first duct l9 engages the lower end 69 of the tube 63 so that when the spray applicator is rotated, the holding plate causes rotation of the nipple but the tube and the first duct remain stationary because of the rotatable flange.
To control the operation of this system, there is a control panel 7 whose main components are illustrated in Figure 2 of the drawings. Power is supplied to a junction 71 and the control can be manual by means of a switch 73 or automatic by means of switch 75~ If the system is on rnanual, a red light indicator 77 is on. If the system is on automatic operation, the green light 79 is on. If the system is on automatic, the timer 81 will automatically initiate the application of insecticide inside the enclosure~ A special switch 82 stops the operation of the fan system (not shown3 ofa barn as soon as the spray applicators~arts its operation.
me delay switch 83 will give a signal to the contactor switch 85 to start or stop the operation, i.e. as soon as the timer 81 or the manual switch 73 are on, the contactor 85 will be responsible for the supply of current until the operation is over.
The operation of the system according to the invention is quite simple. If one wishes to operate manually, it is merely necessary to close the switch 73 which could be mounted outside the enclosure and the application of insecticide will last as long as the switch is on. If one elects to have an automatic operation, the timer is set at a specific time of the day to last any definite period of time and each day, the application of insecticide will start at the same time.
More particularly, the invention is concerned with an arrangement which permits an automatic spraying of an insecticide or the ~ike in a barn, for a given period and at a time of the day when workers are not inside the barn, such as at night.
It is well known that insects, more especially those which are found in barns can be extremely harmful to animals. mis is the reason why it is essential to have a program for spraying insecticides in the environment where the animalq spend an important part of their time.
