Abstract: The invention relates to a rotary lobe pump (100) for conveying a fluid medium containing solids, comprising an inlet opening (111) and an outlet opening (112) for the medium being conveyed, two rotary lobes (121, 122) arranged in a pump casing (140) and having rotary lobe vanes engaging with other, wherein each of the two rotary lobes is fixed torque-resistantly on a respective shaft (131) and can be driven by said respective shaft, and wherein the two shafts are coupled to each other by a transmission gear arranged in a gearbox casing (152). The invention relates in particular to a rotary lobe pump in which the inlet opening and the outlet opening are arranged on a connection casing (151).

Abstract: Described is a comminution device, in particular a comminution device including an adjusting mechanism, the adjusting mechanism including a hydraulic cylinder which is coupled between the first and the second cutting element and is in hydraulic communication with a closed hydraulic and pneumatic volume, which is filled with a hydraulic fluid in a first part and with air in a second part, and the wall of which is at least partially transparent so that the hydraulic fluid level can be read from a scale which displays a wear condition of the first and second cutting element. Also detailed is a comminution device in which a lubricant-filled cavity is formed between a first area and a second area, the volume of the cavity being reduced by an adjusting movement of the second cutting element and which is in fluidic communication with the positive engagement connection in order to supply lubricant to the positive engagement connection.

Abstract: The invention relates to a rotary lobe pump for conveying solids-laden fluids engendered in agriculture, in which the conveyed fluid volume flow adapts itself to different operating modes. For improved self-priming, the rotary lobe pump is designed for vertical mounting of the rotary lobes, wherein an angular gear is provided. The rotary lobes are mounted in a topside or underside cover, wherein the axes of the rotary lobes are vertically oriented. Using one of the covers, the rotary lobes can be vertically removed and maintained without having to dismantle other pump components from the pump housing. The rotary lobes can also be removed together with the angular gear as an integral pump component using one of the covers.

Abstract: Embodiments of the invention relate to an apparatus for discharging a fertilizer in strips onto agriculturally productive land by trailing hoses, which apparatus is designed for installing on the rear of a tank vehicle, with two jibs which can each be pivoted to and fro about a vertical axis (A1, A2) between a discharge position and a transport position. Certain embodiments relate in particular to an apparatus of this type which has a supporting device which is arranged on the apparatus so as to be pivotable about a vertical axis (B) and is designed, in the transport position, to support the jibs in relation to the carriageway in a supporting section spaced apart from the axis (B). Embodiments also relate to a tank vehicle with an apparatus of this type.

Abstract: The invention relates to a cutting device for macerating a free-flowing fluid-solid mixture, having a knife rotor which is mounted in such a manner as to be able to rotate relative to a cutting sieve. Said knife rotor abuts the cutting sieve axially with respect to the direction of its axis of rotation, and is pretensioned against the cutting sieve in the axial dimension. According to the invention, at least one clearance space is included, wherein the same is bounded by at least one first and one second surface, and the first surface is arranged in a manner such that it cannot be displaced in the axial dimension toward the knife rotor, the second surface is arranged in a manner such that it cannot be displaced in the axial dimension toward the cutting sieve, and the first and the second surfaces are arranged such that they cannot rotate about the axis of rotation of the knife rotor with respect to each other.

Abstract: The invention relates to an apparatus (1) for discharging a fertilizer in strips onto agriculturally productive land by means of trailing hoses, which apparatus is designed for installing on the rear of a tank vehicle (100), with two jibs (3) which can each be pivoted to and fro about a vertical axis (A1, A2) between a discharge position and a transport position. The invention relates in particular to an apparatus of this type which has a supporting device (10) which is arranged on the apparatus (1) so as to be pivotable about a vertical axis (B) and is designed, in the transport position, to support the jibs (3) in relation to the carriageway in a supporting section (21) spaced apart from the axis (B). The invention also relates to a tank vehicle with an apparatus of this type.
