A spreading apparatus (10) for spreading granular and/or pulverulent material such as grain, salt, fertiliser and the like is disclosed. The apparatus (10) includes a hopper (11) having a discharge aperture (12), a vibration unit (17) arranged for agitating material within the hopper (11), circuitry (22) arranged for supplying power from a power source to one or more material handling components of the spreading apparatus (11), monitoring the power drawn by the one or more material handling components and controlling operation of the vibration unit (17) in dependence upon said power. In various embodiments, the material handling components may include one or more of: a spreading disk (15) arranged for distributing material received from the discharge aperture (12); an auger (18) extending through the discharge aperture (12); and/or a conveyer belt arranged for conveying material from the discharge aperture to the spreading disk (15). A method for spreading granular and/or pulverulent material is also disclosed.

A spreader assembly may include a hopper configured for receiving a spreadable material, a removable cartridge configured for sliding engagement with the hopper and having a material transportation mechanism configured for receiving the spreadable material from the hopper, and a spreader configured for receiving the spreadable material from the material transportation mechanism and spreading the spreadable material onto a target surface. One of the hopper and the cartridge may include a roller having a roller surface, and the other of the hopper and the cartridge may include a bearing surface configured for rolling engagement with the roller surface. The cartridge may have one or more pull bars to facilitate removal of the cartridge from the hopper. Related methods are described.

SELF-PROPELLED, MULTI-PURPOSE TRANSFER DEVICE, as described in the report and in the attached illustrations, is an equipment used in general agriculture and livestock activities to transfer products to another suitable equipment or place, containing the additional function of spreading products in the soil, therefore called self-propelled. The equipment presents as a differential the fact that it brings together multiple functions such as the possibility of transferring and spreading products in the field or in other applications, such as in sandpits.

The dispensing device and system pivotally attach to a hopper bottom trailer to deliver seed from the trailer to planters located throughout the farm. A main conduit inserts into a housing installed at the hopper of the trailer. A gate opens that allows seed to flow through the hopper into the housing. A main conduit inserts into the housing to collect seed and lift the seed both vertically and horizontally. An auger directs the seed upwards through the main conduit towards the dispensing conduit. The seed then gravitationally feeds downward from the dispensing conduit. A flexible conduit enables the user to direct the seed to different planters without moving the trailer.

The present invention belongs to the field of machines and agricultural implements, more concretely agricultural implements for the mixture and/or distribution of a solid product having variable granulometry, such as, for example, silage, crumbs, clusters, in powder, among others, such as feedstuff and mineral supplements. Moreover, the present invention brings as main advantage, relative to the implements known to the state of the art, the fact that it has a torque limiting means over the movable parts, such as helical pitch threads, augers and/or beater arms, so that there is no overload in the hydraulic system of the implement that is operatively associated to the tractor unit. Further, the invention in question counts on a protection means, with paralyzation and partial reversal and/or rotation reducer, in an independent and/or synchronized form, of the movable parts, in case the hydraulic circuit of the implement detects a pressure that is over the preestablished value, avoiding damages and unscheduled stops of the implement.
