Abstract

Device for registering the number of fillings and emptying of a slurry tank with a float (5), a counter (11 ') which is designed as a non-resettable total counter, a numeric display device (13') with the float (5) in Operationally connected, the float (5) emits at least one signal to the counter (11 ') with each complete float stroke, whereby the numeric display device (13') advances the counter (11 ') by one display step, and wherein a filling stroke and an emptying stroke are defined as a complete float stroke passage, characterized by a further counter (11) which is designed as a resettable day counter.

Description

The invention relates to a device for registering the number of fillings and emptying a slurry tank.

Vehicles for the transport and application of slurry are known in a variety of designs. All have in common the very high purchase and maintenance costs. The high investment for such vehicles only pays off if they are borne by contractors, ie. H. used by agricultural service providers, or by several farms. The costs for a client, or the user fee to be paid by a farm, is usually based on the discharged amount of manure. A simple but sufficiently fair compensation for use can be determined if the number of discharged drum fillings can be determined and registered, so that this determined number of drum fillings forms the basis for a remuneration.

From the DE 196 37 955 A1 a transport vehicle with a chassis and a slurry tank and a float present in the interior of the slurry tank is known, which is characterized in that for registering the number of fillings and discharges of the manure tank, a counter is provided with a numeric display device which is connected to the float in Operational connection is, wherein the float at each full float stroke passage at least one signal to the counter outputs, whereby the numeric display device of the counter is indexed by a display step, and that is defined as a complete float stroke passage, a filling stroke and a discharge stroke.

The aforesaid counter with a numeric display device is a tamper-resistant continuous counter. Accordingly, each discharged cask fillings must be determined by forming the difference of an initial number indicating the numeric display device and the final number upon completion of a job at the counter.

This method proves to be very confusing and time-consuming, especially if a contractor is working for several clients at the same time or processing multiple orders.

Object of the present invention is to provide a device for registering the number of fillings and emptying a slurry tank, which avoids the disadvantages mentioned. This object is achieved by a device according to claim 1 by its characterizing features.

According to the invention, the device for registering the number of fillings and emptying a manure tank on two counters, of which a first as a resettable counter, hereinafter referred to as day counter, and a second as a non-resettable counter, hereinafter referred to as a total counter is formed.

The invention is based on the general idea that a resettable daily counter, for example, for the billing of a client or an order is beneficial, but at the same time a non-resettable total counter as a control and documentation device is absolutely necessary. According to the invention, manipulations of the total meter are not possible, which guarantees the owner of the transport vehicle a reliable basis for determining the user charge and a maintenance company a reliable basis for determining the service life or wear of the transport vehicle.

The two counters can be designed as independent, independent counters. Advantageously, however, the resettable daily counter is only a counter dependent on the mechanical total counter, in particular in the form of an electronic counter, for example a microcontroller. Accordingly, the total meter transmits only an electrical signal to the day counter.

The, preferably electronic counter of the day counter can be reset via a device, for example via a reset button.

In a preferred embodiment, the count of the day counter can be documented. A documentation can be done as paper printout with date, time and number of since the last reset done filling and emptying of slurry tanker or electronically in a memory unit of the device according to the invention.

With the aid of the drawings, the invention will be explained in more detail using an exemplary embodiment. It shows

1 a manure transport trailer with a device for registration and

2 a device for registration in detail.

An in 1 illustrated manure transport trailer 1 has a chassis 2 and a slurry tank 3 on, which with manure 4 filled and emptied again. Inside the manure tank 3 there is a float 5 that has a gearbox 6 with a level indicator 7 connected to the outside of the manure tank 3 located. In the simplest case, the full-level display device consists of a simple pointer 7 , On the outside wall 3a of the manure tank 3 there are marks 8th and 9 , with the help of which the liquid manure level 4 in the slurry tank 3 can be read.

The swimmer 5 moves according to the slurry level and transmits this movement to the pointer 7 , whose pointer tip 7a depending on the level between the level markings 8th and 9 ("Empty" and "full") is located. At the pointer 7 is a magnet as a signal generator 10 arranged, which is aligned with the pointer 7 emotional.

On the outside wall 3a of the manure tank 3 is also at least one counter 11 ' arranged, which is a magnetic field-sensitive sensor 12 having. There is also a further counter 11 provided as from the counter 11 ' dependent electronic counting device is formed. The counters 11 and 11 ' moreover, have a numeric display device 13 . 13 ' on, with the help of which the number of fillings of the manure tank 3 is registered. The day counter 13 is by means of the reset button 14 resettable; the total counter 13 ' is not resettable.

This is the counter 11 ' designed so that the numeric display device 13 ' is advanced by a counting step, if the slurry tank 3 once filled and emptied again. When filling the manure tank 3 changes the pointer tip 7a their display position between "empty" and "full" and with it the magnet changes 10 his position, being at the magnetic field-sensitive sensor 12 of the counter 11 ' is moved past, so that the magnetic field-sensitive sensor 12 generates a signal through which the counter 11 ' is incremented by half a step.

When emptying the manure tank 3 the magnet moves 10 again at the magnetic field-sensitive sensor 12 passing, which in turn generates a signal through which the counter 11 ' a further half step is switched, so that now after filling and emptying a complete counting step has taken place and the numeric display devices 13 and 13 ' are indexed by one digit. To ensure reliable counting, a complete counting step is accomplished by a full float stroke passage, which by definition includes a fill stroke and a drain stroke. The signal output by the magnet 10 or the magnetic field-sensitive sensor 12 must be done so that with short-term fluctuations of the liquid level of the manure 4 no switching steps can take place. This is ensured by suitable measures on the float mechanism, for example by appropriate damping and / or transmission ratios.

To prevent manipulation of the meter reading, the counter is 11 ' non-resettable, so that without unauthorized intervention in the counter 11 ' whose digits display is not changeable, and thus a reliable basis for billing the user fee is created. In contrast, the counter 11 of the day counter from an operator with the reset button 14 be reset. Documentation takes place by means of an electronic storage unit, which can be read out at any time.

The signal generator need not necessarily be realized by a magnet and a corresponding magnetic field-sensitive sensor, but any other signal generator can be used according to the invention with success. Instead of the counter 11 ' with magnetic field-sensitive sensor 12 An electronic counter can also be used successfully in the invention. However, since in agricultural technology rough tolerances high mechanical stability and contamination insensitivity are required, the above-described magneto-mechanical solution is given preference.

The particular advantages of the transport vehicle according to the invention are, above all, the simple and therefore robust construction of its registration device and its manipulation security. By the features specified in the dependent claims, the invention is designed in a particularly advantageous manner.
