    Automatic pellet feed dispenser for animals
    Field of the invention
    The present invention relates to an automatic feed dispensing device in the form of animal granules comprising: - a hopper containing the granules, and the bottom of which opens freely into an open dish in the direction of the feeder, receiving a volume of pellets with the natural slope, - a dispensing piston penetrating in a controlled manner in the slope under the hopper to discharge beyond the weir a quantity of granules corresponding to the displaced volume of the piston during a distribution phase with return of the piston in its retracted position, - A hydraulic actuator comprising a piston housed in a chamber connected in a controlled manner to the water distribution network to be moved by the water inlet of the network, the piston being returned to the retracted position defined by an adjustable stop after cut-off. the water supply.
    State of the art
    Such an automatic feed distribution apparatus described in document FR 98 00685 is already known.
    Although this device gives satisfaction it would be interesting to make it simpler and more automatic.
    Purpose of the invention
    The present invention aims to develop an apparatus of the type defined above to make its operation more efficient both for the distribution of food and drinking water and is a simpler operation.
    DESCRIPTION AND ADVANTAGES OF THE INVENTION To this end, the subject of the invention is an apparatus for automatically dispensing food and beverages for animals, characterized in that it comprises: a water inlet, controlled, connected by a solenoid valve to the actuating chamber of the hydraulic actuator and a jet pump whose outlet opens into an outlet and the inlet is connected to the solenoid valve; a water dish placed in an overflow receptacle; even connected to the suction inlet of the jet pump, - a pipe connecting the actuating chamber to the bowl, - the pipe connected to the bowl and the feed pipe of the jet pump having each much greater pressure losses than those of the supply line of the actuating chamber so that the actuator is controlled primarily with respect to the flow of water into the bowl and the flow of water al imitating the jet pump, and - an adjustable control of the solenoid valve.
    The dispenser according to the invention makes it possible, with the sole control of the water, to ensure both the distribution of the granules and the distribution of the water in the bowl while cleaning the bowl and discharging the cleaning water. by a pump. This allows the dispensing apparatus to be used without regard to the level at which the dispensing apparatus is located to evacuate the cleaning or rinsing water from the bowl. The operation of the apparatus is extremely simple since the only energy to be supplied is that used to control the solenoid valve while the energy controlling the dispensing piston and that ensuring the cleaning of the bowl and its filling is provided by the water under pressure.
    According to another advantageous characteristic the actuator has a housing housing a piston dividing the housing into an actuating chamber connected to the solenoid valve and a chamber housing a spring biasing the piston in the rest position, the piston being connected by a rod to the distributor piston. This embodiment of the actuator is particularly simple, effective and reliable and requires virtually no maintenance.
    According to another advantageous characteristic, an end stop adjustable towards the rest position, this stop being engaged on the rod connecting the pistons and limiting the return stroke of the distributor piston. Adjusting the stop effectively adjusts the feed rate dispensed with each movement of the dispensing piston, thus limiting the recoil of the dispensing piston, that is to say finally the volume displaced at each stroke by the dispensing volume. This adjustable stop does not interfere with the movement of the dispensing piston or the repetition of movement during a single dispensing.
    According to another characteristic, in the case of the abutment adjustable above, the stop is carried by a lever whose one end pivots about an axis and the other bearing a nut engaged on a threaded rod, fixed in translation and controlled rotated by a crank to move the nut and thus adjust the position of the stop. This adjustment device is a particularly simple and reliable embodiment. The adjustment is precise since the displacement of the stop is multiplied by the screwing movement. In addition, the stop may be associated with an index moving on a graduated scale to give an indication of the setting. This index is for example carried by the nut and appears through an opening of the box of the dispensing apparatus or through a window.
    According to another feature, the pipe connecting the actuator actuation chamber to the bowl has a throttle member for adjusting the pressure drop.
    This throttling device makes it possible to precisely adjust the pressure drop in the pipe connected to the bowl to ensure priority control by the actuator before filling the water bowl.
    Although the relative section of the pipe with respect to the other pipe sections makes it possible to define a pressure drop, a throttle element constituted by a simple diaphragm with a screw adjustment allows an accurate adjustment of the relative pressure drop in this pipe. conduct.
    According to another advantageous characteristic, the jet pump has an inlet connected to the pipe coming from the solenoid valve provided with a throttling element making it possible to adjust the pressure drop. This throttling member also makes it possible to adjust the pressure drop at the inlet of the working fluid in the jet pump to balance the operation of the installation both with respect to the distribution of the water in the bowl and cleaning and especially to give priority to the actuator that controls the dispensing piston.
    According to another advantageous characteristic, the top of the weir at the level of the hopper is provided with a pivoting flap, allowing the granules to pass to be poured into the feeder, over the weir, the opening movement of this flap being limited by an abutment. to protect access to the bowl from the outside. drawings
    The present invention will be described in more detail below with reference to an embodiment of an automatic feed and animal feed apparatus shown in the accompanying drawings, in which: FIG. a schematic view of the automatic dispensing apparatus in the rest position, Figure 2 is a schematic sectional view similar to that of Figure 1 showing the apparatus in the activated position. Description of an embodiment of the invention
    According to Figure 1, the invention relates to an automatic dispensing apparatus for food and drink for animals. Foods consist of granules or products similar to grains or granules of varying sizes depending on the animal. The drink is usually water. The apparatus consists of a box 1 grouping the various elements and carrying on the one hand a feeder receiving food (A) and on the other hand a bowl 3 receiving water (E), food and water being distributed automatically by this device.
    The casing 1, preferably of decorative shape, for example in the form of an outer niche, houses a hopper 4 containing the food reserve (granules) (A) to be dispensed. The hopper 4 opens into a cup 41, freely to let the products (A) arrive according to their natural slope (T), in the cup 41 constituting the underside of the hopper 4. The cup 41 is connected to the feeder 1 by via a weir 42 forming a retainer. This spillway 42 holds the granules (A) along the slope of this type of product and when the granules are pushed, they pass over the weir 42 to get into the feeder 2. The outlet of the cup 41 at the weir 42 with restraint is preferably closed by a flap 43 whose opening is itself limited by a stop 44 to leave only the opening sufficient to pass the granules without allowing the animal to open the flap to take directly from food in the cup 41, without waiting for them to arrive in the feeder 2. The apparatus comprises a dispensing piston 5 movably installed at the base of the hopper 41 arriving more or less in the volume of the cup 41 The piston 5 is carried by a rod 51 connected to a hydraulic actuator 6. The hydraulic actuator 6 is constituted by a chamber 61 whose movable partition is the piston 62 connected to the casing 66 of the actuator by a me resilient mbrane 63, the piston 63 is pushed into the rest position as that of Figure 1 by a return spring 64; it rests against one face of the actuator 6 being housed in the other chamber 65 of the housing 66. Between the piston 62 of the actuator and the piston 5 of the distributor, the piston rod 51 passes through a stop 71 of an adjusting member 7 provided with a lever 72 pivoting about an axis 73 and whose other end is carried by a nut 74 traversed by a threaded rod 75 connected to a crank 75. According to the direction and the number of turns that is performed with the crank 76, the nut 74 is moved and consequently the limit stop 71 of the piston 5 which defines the active volume of the piston that is to say the displaced volume by a movement of the piston. An index not shown can be associated with the screen to indicate the position set on a scale, outside the box 1. At each stroke, the piston 5 enters the pile of pellets of the cup 41 dumped from the hopper . The end of advancing stroke of the piston 5, active phase is limited by the stroke of the actuator 6 while the retreat of the piston 5 to its rest position, which is the other extreme position of the piston, is it is defined by the adjustable stop 71. This defines the volume (shown in phantom) of the piston 5 which acts on the volume of granules of the pile of granules (T) of the cup 41. The volume displaced by the piston 5 thus corresponds to the quantity of granules pushed over the weir 42 to fall into the feeder 1. In order to preserve the granules and also to prevent seizing of the piston 5, the latter is preferably constituted by a cylindrical body which can also be replaced by several cylindrical bodies in parallel, increasing the volume displaced at each stroke. It is important for the piston to be a cylindrical body of circular section, for example, so that the return movement of the dispensing piston does not lead to the granules of the pile T but the piston withdraws alone while granules are coming down from the hopper 4 to the hydraulic actuator 6 is controlled by its supply from the water distribution network RE via line 80 and via a solenoid valve 8 controlled by a control circuit. control 9 regulating the operation of the dispensing apparatus. The solenoid valve 8 is connected at the outlet by conduits 81, 82 to both the chamber 62 of the actuator 6 and to the inlet 101 of a jet pump 10 for supplying driving fluid (water under pressure) to both the hydraulic actuator 6 and the jet pump 10.
    The water distribution side of the apparatus is constituted by the bowl 3 placed in an overflow receptacle 31 whose outlet 32 is connected to the suction inlet 102 of the jet pump 10. The dish 3 is fed via a pipe 83 connected to the actuating chamber 61 of the hydraulic actuator 6 so that the water filling of the bowl 3 is at the moment of operation of the actuator 6, by water arriving in the actuator and discharged from the bowl 3 into the receptacle 31 itself connected to the jet pump 10 to suck its water.
    The operation of the automatic dispensing device for food and beverage for animals is controlled from a command 9 to adjust the various parameters. Thus the control 9 regulates the amount of food distributed each time, the periodicity of this distribution accompanied by the distribution of water in the bowl 2 and cleaning by a jet.
    The hydraulic circuit constituted by the lines 81, 82, 83 is managed by the water inlet of the network RE when the solenoid valve 8 is open according to the hierarchy of operations to be performed. In fact, the pressure drops in the water pipes 83, 82 connecting the outlet of the actuator chamber 61 to the water dish 3 and to the jet pump 10 are greater than the pressure losses in the pipe. 81 supplying the chamber 61 of the actuator 6 so that this power is a priority. The pressure losses are defined by the lines 82, 83, that is to say their sections and their lengths or in addition by adjustable diaphragm pressure-loss adjusting members 821, 831 at the inlet of the pump 10 and on the pipe 83. Then once the chamber 61 filled, that is to say when the piston 62 moved to the active position at the end of the race, the water arrives in the bowl 3 and at the same time in the jet pump 10 for sucking the water from the receptacle 31 by overflow of the dish 3. The outlet jet of the pipe 83 feeding the bowl is a directed jet tangentially so as to circulate the inlet water in a rotating and cleaning movement before overflowing the edge of the bowl 3 and pass into the receptacle 31 is thus cleaned at each filling. The outlet 32 of the receptacle 31 is connected by a pipe 84 to the suction inlet 102 of the jet pump 10 whose outlet 103 is connected to the outlet.
    The automatic operation of the apparatus is cyclically controlled by the control 9 according to the parameters set and the quantity of granules loaded at each operation in the feed trough 1. The parameters introduced into the control 9 are notably the following: the instants of distribution in general according to a daily frequency and at fixed times, - the duration of the distribution.
    Other parameters such as the volume of granules of each distribution are adjusted by the adjusting member of the stroke of the dispensing piston (5). For the volume thus displaced by the piston, it is possible to set in the control (9) a repetition of the dispensing cycle during the same dispensing operation to control the dispensing of a volume of food which is a multiple of the volume moved at each stroke by the distributor piston 5.
    The automatic operation of the dispenser is preferably in a simple manner, by a single movement of the piston 5 by acting on the adjustable duration of the distribution. The duration of a distribution includes the time required to advance the piston 5 to its advanced end of stroke position and additional time corresponding to the cleaning and filling of the bowl 3 with water.
    In fact: during the first distribution phase, the water coming from the network RE feeds chamber 61 primarily, although water can also escape from chamber 61 and pass through line 83 into the bowl 3 or through the pipe 82 in the jet pump 10. But the main flow of pressurized water fills the chamber 61 by pushing the piston 62 against the action of the spring 64.
    During the second distribution phase which continues the first phase without discontinuity, when the chamber 61 is filled, the pressurized water escapes through the pipe 83 into the bowl 3 since the piston 62 can not be pushed back beyond from its end position. Due to the orientation of the jet, the water circulates in a circle in the bowl 3 and cleans it overflowing to cause any waste in the receptacle 31. From there, the water is discharged by suction by the jet pump 10 which also is fed during this time by the pipe 82.
    While the valve 8 is open, there is sufficient pressure in the chamber 62 which keeps the piston 61 and thus the piston 5 immobile in the advanced position. At the end of the distribution period, the solenoid valve 8 closes, the pressure drops in the chamber 61 and the spring 64 pushes the piston 62 which delivers the water into the bowl 3 and into the jet pump 10 which then still pump the receptacle 31. The jet arriving in the bowl 3 is no longer powerful enough to eject the water in the receptacle 32 so that the bowl 3 fills with water.
    The adjustment of the duration is such that it allows the cleaning and the filling of the dish 3. Depending on the quantity of food required by the animal and the quantity of water, it is necessary to define the number of depending on the amount of water needed daily and adjust the volume of food distributed each time by setting by the device. But if the total daily quantity of food is not reached in this way, one can multiply the distributions with each time the maximum quantity of granules at the price then of a quantity of water in excess, which does not intervene practically not in the cost of this automatic distribution.
    Another solution is to control several operating cycles of the dispensing piston 5 during the same distribution phase. This is done by several closures / openings of the solenoid valve 8 so that the piston 5 can each time return to its rest position then the valve 8 is opened again, and the piston 62 controls a new stroke of the distribution piston 5 And so on.
    Thus, in summary the operation of the dispensing device is only by the signal S sent by the control 9 which opens the solenoid valve 8 and keeps it open as long as the signal is applied.
    Figure 2 shows the dispenser of Figure 1 in dispensing position. The piston 61 is advanced by the arrival of water in the chamber 61 which maintains the distributor piston 5 in the advanced position. The granules are discharged over the weir 42 in the feeder 1 and the water of the pipe 83 filled the dish 2.
