Abstract

The slurry distributor is for a tanker vehicle, the slurry being forced or pumped under pressure out of the tank and distributed by a scatter plate. A distributor pipe (11), is flexible for at least part of its length and is mounted in bearings (3) on a bracket (2) at the outlet from the tank (1). Actuators (7) functioning in opposite directions act on the shaft (4) in the bearings via levers (6). A lever-operated hose clamp (8, 9) is coupled to the shaft so as to shut the distributor pipe off when travelling.

Slurry distributors for tank vehicles

Field of application of the invention:

The invention relates to a liquid manure distributor for tank vehicles, in which the manure is pressed by tiberdruck from the tank and sprayed freely.

Characteristic of the known technical solutions:

Various manure spreaders are known which distribute the manure directly over a baffle plate. These have a short neck with a manually operated or remote-operated gate valve, which can also be opened by remote control for a short while, in order to eliminate blockages and which automatically returns to a partially open position. At this gate valve is connected to a nozzle with the manifold. If the nozzle is short, the liquid manure pollutes the vehicle and the tail light. This contradicts the Highway Code. A long neck is contrary to the road traffic regulations, as the construction may protrude a maximum of 1 m above the rear axle, otherwise it requires underrun protection for tankers with a total mass over 10 t, which makes the vehicle more expensive. The taillights must not be more than 1 m from the projecting end, which in turn causes pollution. A detachable longer manure spreader, which is removed when driving on the road, requires additional manual work with great effort and causes contamination of the operator.

It's in the BUD-OS. ' 1 926 835. Slurry described suction pipe, which is attached to the rear Faßboden and protrudes when refueling the vehicle on the permissible width for road transport width. In this solution, the requirement of StVZO was met by the fact that, the two, connected by a movable piece of hose pipes are lifted by means of a hydraulic cylinder, so that they do not exceed the side profile of the vehicle.

Object of the invention:

The aim of the invention is to further mechanize the manure spreading and to reduce the physically heavy and dirty work to a minimum.

Explanation of the essence of the invention:

The technical task is to spread the manure as far away from the vehicle as possible by means of a long distribution pipe and to bring the distribution pipe in road transport in such a position that it does not exceed the permissible profile.

Features of the invention:

The goal is achieved and the technical task "solved by the at least a partially flexible distribution pipe is mounted horizontally or vertically pivotally by means of a support structure at the rear tank bottom.

The lifting shaft and the return device for the pivoting mechanism and the locking device for the flexible distributor tube are also connected to the bearing shaft. The locking device consists of the elastic counter bearing and a lever operated pressure roller and a contact switch for control of the cab. To compensate for wall thickness differences in the flexible manifold, it is expedient to use instead of rigid levers, tension or compression springs on which the pressure roller attached

is.

The mode of action is the following:

In the transport and filling state, the distributor tube is swung out of the working position upwards or to the side. The pressure roller presses the elastic piece of the manifold together and locks the spout. The required force for swinging and closing the distributor is effected either by a pneumatic or hydraulic cylinder and the pivoting back and open by means of rotary and tension spring or vice versa, by a corresponding spring causes the swinging and closing and by means of a remote-controlled cylinder, the device in Working position is brought. It can also be used as well as a double-acting cylinder. The driver has control by a signal lamp, which is displayed by a contact switch on the swivel mechanism.

The invention has the advantage that on the way back the container can be evacuated again, the provisions of the Highway Code and the Road Traffic Licensing Regulations are met in the national and international context and heavy physical work and contamination deleted. The system is robust and maintenance-free. By eliminating the slide it can no longer freeze.

Embodiment:

The invention will be explained below with reference to two embodiments.

Show it:

1: the liquid manure distributor in working position FIG. 2: the liquid manure distributor in drive division with reversed actuating elements, and FIG. 3 ^: another variant of the closing device.

As shown in FIG. 1, located at the manure tank 1 a console 2 with the bearing 3 and the bearing shaft 4-. On the shaft 4, a tension or torsion spring 5 engages at the

at 6 on. Likewise, instead of the spring 5 gravity of the manure spreader could be used in conjunction with the inflating elastic tube 11 for the opening process. On the lever 6 or another Hebei, which is non-positively connected to the shaft, engages a piston rod of a pneumatic or hydraulic cylinder 7, which exerts a force opposite to the spring force. Also frictionally with

. connected to the shaft 4 is a lever pair 8, at the free end of a pressure roller 9 · is attached. In the closed position of the pressure roller 9 is the elastic pressure plate 10 opposite, which should cause some protection of the elastic manifold 11 against crushing. Since the elasticity of this pressure plate 10 is limited and a greater tolerance in the closed position is appropriate by deforming the lever or variations in the tube thickness, a variant is shown in Fig. 3, which allows this tolerance. Instead of the rigid lever pair 8 can train or compression springs 12 are used, which have a corresponding to the required closing pressure resistance moment against deflection. Thus, the closing force is fairly constant, and the closure of the manifold 11 can already be made before it has reached its end position.

The manifold 11 may be an internally rubberized fabric tube, as used for example for fire fighting purposes, as this inflates due to the pressure of the tank. The nozzle 13 and the spray plate 14 are located at the end of this distributor tube 11. The distributor tube 11 can also be designed to be elastic in the region of the bend and the end piece to be rigid. If the distributor tube 11 is rigid, this can be connected to the shaft 4 with force. An elastic hose must be mounted on a support arm 15, which is either fixedly connected to the shaft 4 or rotates about this and is pivoted by means of the lever 16. As shown in FIG. 2, the closure is effected by spring force. The opening and swinging out of the distributor

tube 11 in the working position is carried out by the working cylinder 7 ·

Pig. 3 shows an advantageous variant for actuating the pressure roller. The deflection of the spring causes premature closure of the spout, so that the residual slurry does not splash the vehicle. In addition, this has the advantage that manufacturing and operating tolerances between pressure wave and pressure plate 10 are better compensated. Furthermore, the preloaded spring supports the opening process, especially when using gravity.

To control it is expedient in both embodiments to attach to the shaft 4 a contact with limit switch 16, which signals the position of the manifold and the position of the locking device to the driver. In both embodiments, it is possible to make the arrangement so that the manifold 11 is pivoted in the transport position both upwards or to the side. For the lateral pivoting only the nozzle needs to be offset so far laterally that the spray plate 14 · does not exceed the side profile in the Ausschwenkzustand.
