The invention belongs to transportation machinery, in particular to an arbitrarily curved multi-drive mobile belt conveyor suitable for bulk material transportation, which consists of a head frame (1), a tail frame (20), a main motor (2), and a travel motor ( 17), idler frame (6), lower idler roller (33) and adhesive tape (50), a driving roller shaft (34 ), two driving drums (5) are fixed on the driving drum shaft (34), a driving drum groove (48) is left between the driving drums (5), and a machine head row wheel (37) is installed under the head frame (1) ;The belt conveyor can be bent at any number of points in the vertical and horizontal directions, and has strong adaptability; the belt will not deviate. Due to the multi-point drive, the tension of the belt is reduced, so the use level of the belt will be reduced, the initial investment cost will be reduced, and the use of the belt will be extended. Long life, improve transportation efficiency; it can move by itself and bend at will.

The invention relates to an automatic conveying belt regulating device used for a belt-type conveyor. A beam which is parallelly and fixedly connected with a belt-type conveyor frame is arranged on the device; two V-shaped swing carrier-roller brackets are correspondingly arranged rightward and leftward above the beam and are coaxially articulated with the beam by a connecting shaft; a middle supporting column is vertically arranged in the middle of each of the two swing carrier-roller brackets; a set of side supporting columns are correspondingly and vertically arranged at the two sides of each swing carrier-roller bracket; the shaft ends of two respectively correspondingly arranged rollers are correspondingly clamped onto the side supporting columns and the middle supporting columns respectively, the rollers revolve around the central shafts and roller surfaces are contacted with the conveying belt; limiting baffles are respectively arranged on the beam corresponding to the lower parts of the inner sides of the swing carrier-roller brackets; a fixed carrier-roller bracket is parallelly arranged right in front of the beam, a set of the side supporting columns are correspondingly and vertically arranged at the two sides, the shaft ends of the arranged rollers are correspondingly clamped onto the side supporting columns respectively and the rollers revolve around the central shafts. The device can avoid the rising or the bending of the conveying belt by automatic regulation and correction so as to effectively guarantee the stable and reliable running of the conveying belt.

The invention provides a heavy-duty dumper, which aims to solve the problem that the prior dumper is only suitable for low-power sealing-tape machines and is not suitable for high-power belt conveyers used by large-scale enterprises such as large-scale power stations. The key points of the heavy-duty dumper comprise the following: the heavy-duty dumper is provided with a main belt and two side chutes which are connected with a hopper; a guide chute, a receiving buffer device and the main belt are arranged under the hopper in turn; the buffer device is provided with a buffer roller frame body and a buffer roller set; rubber rings are arranged on surfaces of buffer rollers; a driving running gear adopts a variable-frequency motor; a sealing device is arranged inside each side chute and consists of an adhesive tape provided with a framework, a bearing roller, a clamping device, a tensioning device, a support, a clamping device support and a tensioning device tailstock; the bearing roller is fixed on a chute body; the special adhesive tape provided with the framework passes by the bearing roller; and a sealing adhesive tape is arranged above a bin opening by which discharged materials of the chute pass and passes by two side walls and the upper part of the chute. The heavy-duty dumper is suitable for the belt conveyers which are operated in high power.

The invention relates to the field of agricultural machinery equipment, and in particular relates to a seed metering single body for a plant-to-row drill seeder with high sowing efficiency. The seed metering single body comprises a seed metering deice and a seed storing device which are fixedly arranged on a machine body, wherein the seed metering device comprises an installing base, a seed metering opening is formed in one side of the installing base, a machine drives a rotating bevel gear, the upper part of the bevel gear is sequentially provided with a cone base and a hollow cone which are linked with the bevel gear, a tensioning roller is arranged at one side of the cone, the seed metering opening is formed between the cone and the tensioning roller, and a driving woven belt is packed outside the cone and the tensioning roller; the seed storing device comprises a glass seed storing sleeve and a seed storing hopper, and the lower part of the seed storing sleeve is tightly clamped with the top end of the cone. The seed metering single body provided by the invention has the advantages of being simple in structure, even in seeding, high in self-cleanliness, and small in seed damage.

The invention belongs to the field of solid-liquid separation equipment and particularly relates to a double-belt non-deflection rubber belt vacuum filter. The double-belt non-deflection rubber belt vacuum filter comprises a rubber belt (2), a filter cloth belt (3), rubber belt driving / driven wheels (4, 5), filter cloth belt driving / driven wheels (6, 7, 8), a vacuum box (12) and a gas-liquid separator (9), wherein the working surface of the filter cloth belt (3) is attached to the rubber belt (2); the rubber belt driving / driven wheels (4, 5) are in matched connection with the rubber belt (2);the filter cloth belt driving / driven wheels (6, 7, 8) are in matched connection with the filter cloth belt (3); the vacuum box (12) is fixed below the rubber belt; the gas-liquid separator (9) is provided with a vacuum pump (10); an inlet of the gas-liquid separator (9) is communicated with the vacuum box (12) through a pipeline; the end parts of the two sides of the rubber belt (2) and the filter cloth belt (3) are both provided with a chain wheel transmission mechanism; and the filter cloth belt driving / driven wheels (6, 7, 8) and the rubber belt driving / driven wheels (4, 5) adopt chain wheels meshed with the chain wheel transmission mechanisms. A system is convenient to maintain. The double-belt non-deflection rubber belt vacuum filter has a low cost and high transmission performance and guidance performance. The phenomenon of deflection of the rubber belt and the filter cloth belt can be effectively prevented.

The invention relates to a soil gas flux detector comprising a soil ring (1), supporting legs (2), a pedestal (20), a gas chamber (7), a protective cover (8), a line passing shaft (9), and a control box (19). The flux detector is characterized in that a sealing ring (5) and a pressing ring (3) are arranged above the pedestal (20); the supporting legs (2) are arranged below the pedestal (20); supporting led slide grooves (16) and supporting leg rotation shafts (14) are arranged on the supporting legs (2); a buffering device (8-7) is arranged in the gas chamber (7), the protective cover (8), and the line passing shaft (9); and a return button (19-4) is arranged on the control box (19).
