The invention relates to a device for cleaning a functional surface for guiding or treating a material web, preferably a non-woven web. The device comprises a pivotably mounted roller body, a plurality of hollow cylindrical brush segments being disposed on the circumference thereof and positively connected to each other and tensioned between two adjusting rings disposed at the circumference of the roller body. According to the invention, in order to ensure secure tensioning of the brush segments regardless of the surrounding conditions, at least one of the adjusting rings is axially flexibly retained at the circumference of the roller body and a compression ring rotational fixed to the flexible adjusting rings is axially tensioned against the roller body by means of at least one spring element, such that an axial force acting on the brush segments is generated.

The invention relates to a self-propelled insect suction machine and belongs to the technical field of agricultural and forestry machines. The air outlet of the suction fan of the self-propelled insect suction machine leads to a filter bag. The air inlets of the suction fan are divided into three loops and are respectively connected with a middle insect suction nozzle, a left insect suction nozzle and a right insect suction nozzle through air inlet hoses. Slip insect suction ports with a sundries preventing net are arranged on the lower surface of the shell of each insect suction nozzle. The two sides of the middle insect suction nozzle are respectively hinged with the adjacent ends of the left insect suction nozzle and the right insect suction nozzle. A telescopic cylinder is installed at each hinged position. When the telescopic cylinders are in an extended state, the left insect suction nozzle, the right insect suction nozzle and the middle insect suction nozzle are arranged at thesame level; and when the telescopic cylinders are in a contracted state, the length directions of the left insect suction nozzle and the right insect suction nozzle are perpendicular to the length direction of the middle insect suction nozzle, and the left insect suction nozzle and the right insect suction nozzle are in a folded state. When the self-propelled insect suction machine works, the suction fan continuously sucks in air flows with insects from the insect suction nozzles, the air flows are delivered to the filter bag, the insects are intercepted into the filter bag through filtrationand therefore the pollution-free physical deinsectization is realized.

The application relates to a screed assembly (1) for laying a road surface (3), said screed assembly (1) determining a working width (W), viewed in the working direction (R), for the laying of the road surface (3), and a working station (9) for an operator (P) being mounted on the screed assembly (1). The working station (9) is mounted on the screed assembly (1) in a vibration-decoupled manner, such that the transmission of vibrations from the screed assembly (1) to the working station (9) can be reduced or prevented.

An apparatus for removing molten mass, especially chocolate mass, from a rear bottom portion of items, especially confectionaries, includes a first and a second conveyor belt for transporting the items in a conveying direction perpendicular to the working width of the apparatus. The second conveyor belt is located adjacent to the fist conveyor belt and downstream of the first conveyor belt as seen in the conveying direction. A driven hollow shaft is located in a gap portion between the two conveyor belts, it extends over the working width, and it is supported from its inside and within the working width.

A pair of large propellers is used for constructing ''reversing propellers with a common rod'', rotating shafts of two propeller disks and a rod form an isoceles triangle, the lower surfaces of the two propeller disks are positioned at an arc line, and the length of the rod is longer than the diameter of the propeller disks; a pair of small propellers is used for constructing ''reversing propellers with a common shaft'', and the small propellers are made in the shape of arcs; through several carbon fiber tubes and connecting fixing pieces, the ''reversing propellers with a common rod'' and the ''reversing propellers with a common shaft'' form a four-rotor unmanned aerial vehicle structure which is in mirror symmetry in left and right and asymmetrical in front and back, and the rod is perpendicular to the shaft; the direction of downwash flow is the direction of an outward normal of cambered surfaces; therefore, the four-rotor agricultural unmanned aerial vehicle with the blades in cambered surface distribution is named. Compared with a four-rotor unmanned aerial vehicle with blades in the structure of horizontal distribution and central symmetry sold in the market, the four-rotor agricultural unmanned aerial vehicle with the blades in cambered surface distribution has the advantages that the flow rate of the downwash flow is effectively reduced, the area of the downwash flow is enlarged, crops are protected, and the working performance is improved.

The invention provides a subsoiling and rotary cultivating machine with a working width of 420cm. The subsoiling and rotary cultivating machine comprises a blade shaft assembly, a box assembly, landing legs, landing leg sleeves, a planker, a planker bolt, a reinforcing rod, a suspension bracket, an intermediate transition bearing block assembly, a universal joint and a break shovel, and is characterized in that subsoiling and rotary cultivating operations can be finished for one time, the working width is 420cm and in the shape of the break shovel; six rotary blades are arranged on the blade shaft assembly; the height of the landing legs can be adjusted via the landing leg sleeves; a compression spring is positioned on the reinforcing rod and used for controlling the planker; the planker is arranged on the planker bolt and used for levelling the land after the subsoiling and rotary cultivating operations under the action of the reinforcing rod; the suspension bracket is used for connecting with a tractor; and the intermediate transition bearing block assembly and the universal joint are used for transferring the power. The subsoiling and rotary cultivating machine has the advantages of large working width, simple structure, safety, reliability and easiness in operation, etc.
