Abstract

A combined trailed slurry and dung spreader comprises a hollow body in the form of an elongate cylinder (1) having wheels (2). At the front end of the cylinder (1) there are lower and upper power take-off connections (6, 14). The lower connection (6) drives an impeller (7) mounted in a cylindrical chamber (8) at the bottom of the rear end of the cylinder (1), via a shaft (9). The upper connection (14) drives a shaft (12) mounted axially of and within the cylinder (1), via reduction gearing (15). The impeller chamber (8) has a tangential and upright discharge pipe (10) leading to a nozzle (11) for slurry. The shaft (12) has flail chains (13) for discharge of dung from the cylinder (1) through an opening in an upper side quarter in the cylinder (1), which opening can be closed by a cover when discharging slurry. When the lower connection (6) is connected to the power take-off connection of the tractor the rear end of the cylinder (1) is lower than the front end so that slurry is fed by gravity to the impeller chamber (8). However, when the upper connection (14) is so connected the cylinder (1) is substantially horizontal for dung discharge. <IMAGE>

Description

SPECIFICATION Combined Trailed Slurry and Dung Spreader This invention relates to a combined trailed slurry and dung spreader.

Heretofore trailed slurry spreaders and trailed dung spreaders have been constructed as separate items of equipment. It is the object of the invention to provide a single item of equipment which serves for both purposes.

Known trailed slurry spreaders usually comprise a wheeled hollow body in the form of an elongate hopper with an openable cover at the top and downwardly and inwardly sloping side walls converging towards an elongate auger chamber at the bottom. At the front end of the auger is a power take-off connection and at the rear end is an impeller mounted for rotation in a cylindrical impeller chamber. A discharge pipe is connected tangentially to the impeller chamber and leads upwardly to a discharge nozzle placed high on the rear of the body. Slurry within the body is fed along the auger chamber into the impeller chamber where it is forced through the pipe and out of the nozzle rearwardly of the body.

Known trailed dung spreaders usually comprise a wheeled hollow body in the form of an elongate cylinder open along an upper side quarter of the cylinder. Axially of and within the cylinder is a rotatable shaft driven through a reduction gearing from a power take-off connection at the front end of the body. Flail chains are attached to the shaft and throw dung tangentially out of the opening in the cylinder laterally of the body.

According to the invention there is provided a combined trailed slurry and dung spreader comprising a wheeled hollow body in the form of an elongate cylinder which has an opening and a cover which can be moved between two extreme positions about the cylinder, one extreme position closing the opening for slurry spreading and the other extreme position rendering the cylinder open along an upper side quarter thereof for dung spreading, a lower power take-off connection at the bottom of the front end of the cylinder, an impeller mounted for rotation in a cylindrical impeller chamber at the bottom of the rear end of the cylinder, a lower shaft under the cylinder interconnecting the lower power take-off connection and the impeller, a discharge pipe connected tangentially to the impeller chamber and leading upwardly to a discharge nozzle placed high on the rear of the cylinder, the lower power take-off connection being sufficiently low that when it is connected to the power take-off connection of the tractor the cylinder is tilted with the rear end lower than the front end so that the slurry is fed by gravity to the impeller chamber for discharge from the nozzle, an upper shaft mounted axially of and within the cylinder, flail chains attached to the upper shaft, and an upper power take-off connection for driving the upper shaft so that when the upper power takeoff connection is connected to the power take-off connection of the tractor the cylinder is substantially horizontal for dung spreading.

An embodiment of the invention will now be described, by way of example, with reference to the accompanying drawings, in which: Fig. 1 shows a combined trailed slurry and dung spreader from one side; Fig. 2 shows the spreader from the front in a mode for slurry spreading; and Fig. 3 shows the same as Fig. 2 but in a mode for dung spreading.

In the drawings a combined trailed slurry and dung spreader comprises a hollow body in the form of an elongate cylinder 1 having ground-engaging wheels 2. The cylinder 1 has an opening 3 and a cover 4 which can be moved between two extreme positions about the cylinder 1. In one extreme position the cover 4 closes the opening 3 for slurry spreading (as shown in Fig.2) and in the other extreme position the cover 4 renders the cylinder 1 open along an upper side quarter thereof (as shown in Fig. 3). The cover 4 has a lidded spigot 5 into which a delivery end of a hose from a slurry pump can be inserted for filling the cylinder with slurry while the opening 3 is closed by the cover 4.

A lower power take-off connection 6 is provided at the bottom of the front end of the cylinder 1, an impeller 7 is mounted for rotation in a cylindrical impeller chamber 8 at the bottom of the rear end of the cylinder 1 and a lower shaft 9 under the cylinder 1 interconnects the lower power take-off connection 6 and the impeller 7. A discharge pipe 10 is connected tangentially to the impeller chamber 8 and leads upwardly to a discharge nozzle 11 placed high on the rear end of the cylinder. The lower power take-off connection 6 is sufficiently low that when it is connected to the power take-off connection of the tractor (not shown) the cylinder 1 is tilted with the rear end lower than the front end so that slurry is fed by gravity to the impeller chamber 8 for discharge from the nozzle 11.

An upper shaft 12 is mounted axially of and within the cylinder 1 and flail chains 13 are attached to the shaft 12. An upper power take-off connection 14 drives the upper shaft 12 via a reduction gearing 15 which may be a chain-and-sprocket gearing. Since the connection 14 is higher than the connection 6, when the connection 14 is connected to the power take-off connection of the tractor the cylinder 1 is substantially horizontal for dung spreading. When dung spreading a plate 16 (see Fig. 1) is placed in a connection 17 between the cylinder 1 and the impeller chamber 8.
