The invention discloses a hydraulic drive mechanism of a heliostat. The cylinder earrings (28, 29) of first and second linear hydraulic cylinders (6, 7) are articulated with a support plate (5) on a support beam (4), and piston rod earrings (27, 9) are articulated with a drive arm plate 11. A support arm (26) of a support fork (23) is articulated with a support plate (18) of a connection cylinder (22). A cylinder earring (44) of a third linear hydraulic cylinder (16) is articulated with an upper support plate (13), and a piston rod earring (20) is articulated with the support plate (18). The linear hydraulic cylinders (6, 7) drive a horizontal main shaft (15) to rotate, and drive a heliostat reflecting surface (24) and the linear hydraulic cylinder (16) to rotate around a horizontal main shaft axis (100); and the third linear hydraulic cylinder (16) drives the connection cylinder (22) to drive the heliostat reflecting surface (24) to rotate around a common axis (50), so that the heliostat realizes sun tracking.

The invention discloses an ultralow-dose X-ray human body security check system with two channels, which comprises an X-ray source, an alignment part, a check channel, a mobile check platform, a platform driving mechanism, an X-ray detector, an image acquisition and processing device, a control device and an operating console, wherein the check channel comprises two channels, namely a right channel and a left channel which are in parallel with each other; the left channel inlet of the left channel is at left; the outlet of the left channel is in front of the inlet of the right channel; the right channel inlet of the right channel is at right; the outlet of the right channel is in front of the inlet of the left channel; the reciprocating mobile check platforms are arranged between the inlets of the left channel and the left channel as well as the outlets of the right channel and the left channel; the mobile check platform is driven by a platform driving device to convey checked objectsto the right end or left end of the channel in a cycling and reciprocated mode through the inlet of the left channel or the inlet of the right channel after the check is finished; and the checked objects go out of the check channels from the outlet of the left channel or the outlet of the right channel. The invention can improve the equipment inspection capacity and the clearance efficiency in a duplication mode.

The invention provides a balanced crushing control process in the production of sand and gravel, which includes the following steps: coarse crushing, the raw material enters the jaw crusher through a rod feeder for coarse crushing; a sieve, the coarse material enters the secondary crushing and then enters the first sieve , the fine material enters the second sieve, and part of the fine material enters the intermediate crushing link with the coarse material for circular crushing; the second sieve uses a finer screen than the first sieve for the second sieve, the coarse material enters the fine crushing, and after the fine crushing enters the third sieve, the fine material Enter the finished product silo; three sieves, the coarse material enters the fine crushing again, the fine material enters the fine crushing adjustment silo, and part of the fine material enters the fine crushing link together with the coarse material for circular crushing. The invention enables the gaps between the large stones in each crushing link to be filled, reduces the phenomenon of the crusher shed, and enhances the crushing effect; in addition, reduces the difficulty and complexity of capacity coordination and matching between the crushing links, and improves The efficiency of the production system operation is improved, and the proportion of aggregates at all levels is easy to control.

The invention belongs to the technical field of tobacco equipment, and provides an off-line detection system for a blast capsule filter rod. The off-line detection system for a blast capsule filter rod comprises a body, a blast capsule filter rod hopper, a negative pressure fan, an air filter, an air compressor, an oil-water separator, a microwave detecting device, a blast capsule filter rod beltconveying device, a silencer, a static eliminator, a control system, a PLC controller, a high speed solenoid valve, a blast capsule filter rod taking wheel, a negative pressure suction belt conveyingdevice, a double acceleration wheel conveying device, a blast capsule filter rod rolling out wheel, and an unloading rod mechanical shift fork, wherein the blast capsule filter rod taking wheel, the negative pressure suction belt conveying device, the double acceleration wheel conveying device, the blast capsule filter rod rolling out wheel and the unloading rod mechanical shift fork are detachably connected to the body through hole slots. The off-line detection system for a blast capsule filter rod has the advantages that the detection system is simple and convenient to operate; the blast capsule filter rod is not subject to secondary pollution of the detection process; the detection is at a uniform speed and is stable and reliable; the detection accuracy is high; the noise is low; the detection efficiency is high; the maintenance is convenient; and the blast capsule filter rod detected by the off-line detection system has high quality.

A composite peristaltic pump comprises a pump base, a mandrel, an assembling bearing, an upper pump head, a lower pump head, an upper pump casing, a lower pump casing, limit bases, pump head covers, clamping grooves, an electromagnetic base, pump casing covers and a stepping motor, wherein the mandrel is fixed on the pump base through the assembling bearing and fixedly connected with a shaft of the stepping motor, the upper pump head and the lower pump head are arranged on the mandrel in overlapped mode, the upper pump head is formed by a driving wheel, a driven wheel and a ratchet wheel mechanism, and the electromagnetic base is fixed in the pump base and controls moving, opening and closing of the upper pump casing and the lower pump casing through electromagnetic force. The clamping grooves are arranged at two ends of the pump base and are in shaft connection with the limit bases arranged at two ends of the pump base, and the flexibly rotating clamping grooves can be used for ensuring that positions of two pump pipes in the pump heads are reliable. The ratchet wheel mechanism is arranged between the driving wheel and the driven wheel, the driving wheel can drive the driven wheel to rotate unidirectionally, the upper pump head stops rotating when the motor shaft rotates in the reverse direction, and therefore the purpose of pumping liquid synchronously and evenly in the reverse direction in proportion is achieved.
