[0027] A working principle of a conveying device for a beef processing production line: four battery packs 21 provide power supply, first control the two first electric push rods 72 to open and drive the two groups of positioning heads 73 to move outwards and clamp into the two groups of positioning seats 74, then control the double-headed motor 71 to open and drive the two groups of main bevel gears 75 on the two groups of positioning seats 74 to rotate through the two groups of positioning heads 73 clamped in place, and the two groups of main bevel gears 75 drive the threaded rods 81 on the two groups of secondary bevel gears 76 to rotate accordingly, and the slide 84 and the reserved slide groove play a sliding limit role on the threaded sleeve 82, then the two threaded rods 81 drive the supports 83 on the two groups of threaded sleeves 82 to move downward, and the two groups of supports 8 3 drives the tensioning roller 85 to move downward, until the tensioning roller 85 drives the conveyor belt 86 to press down to the predetermined position, so that the conveyor belt 86 is closely fitted with the plurality of transmission rollers on the conveyor frame 1, firstly controls the double-headed motor 71 to pause, then controls the two first electric push rods 72 to close and drives the two groups of positioning heads 73 to move inward and separate from the two groups of positioning seats 74 to the initial position, then controls the servo motor 2 to start through the chain and drives the plurality of transmission rollers on the conveyor frame 1 to rotate successively, and the two groups of supports 83 provide rotation support for the tensioning roller 85, then the plurality of transmission rollers drive the conveyor belt 86 to rotate in a tensioned and orderly manner, and the beef blocks thereon are conveyed smoothly and efficiently; During the conveying of beef chunks by the conveyor belt 86 after the tension is adaptively adjusted, the double-headed motor 71 is first controlled to be continuously turned on and drive the two sets of main circular gears 91 to rotate synchronously, the two sets of main circular gears 91 drive the four sets of slave circular gears 92 to rotate accordingly, the belt grooves 93 on the four sets of slave circular gears 92 drive the four sets of synchronous wheel racks 94 to rotate through four synchronous belts, the four sets of synchronous wheel racks 94 drive the four sets of driving synchronous wheels 95 to rotate accordingly, the four sets of driving synchronous wheels 95 drive the two cleaning racks 96 to rotate in the two sets of collecting racks 4, and the conveyor belt 8 is cleaned by the brush head. 6. Grease and coagulated blood adhering to the two sides of the area are cleaned and removed. At the same time, the four groups of slave circular gears 92 drive the pistons 103 on the four connecting rods 102 through the four groups of cams 101 to reciprocate in the four groups of piston cylinders 5. When the four groups of pistons 103 are in the return state in the four groups of piston cylinders 5, negative pressure suction is generated in the four groups of piston cylinders 5 and the cleaning liquid pre-filled in the two groups of liquid storage pots 106 is sucked into the four groups of piston cylinders 5 through the three-way pipes 105 on the four groups of three-way valves 104. When the four groups of pistons 103 are in the four groups of piston cylinders 5, the cleaning liquid is sucked into the four groups of piston cylinders 5. In the process state, the cleaning liquid sucked into the four groups of piston cylinders 5 is pressurized and supplied to the four pressurizing pipes 111, and then passes through the four groups of rotating joints 112 and the connecting joints 113 in turn to reach the pressurizing chamber 114 in the two cleaning racks 96 in the rotating state, and then successively reaches the injection chamber 115 in the brush head. The pressurized cleaning liquid is then sprayed from the injection holes 116 on the brush heads of the two cleaning racks 96 to the two sides of the bottom of the conveyor belt 86, and the two sides of the bottom of the conveyor belt 86 are cleaned and rinsed at the same time, and the detached grease and blood are washed accordingly. The liquid is gathered in two groups of collecting racks 4, and is sequentially filtered through two groups of primary filter screens 14, secondary filter cotton 15 and tertiary filter screens 16 to perform three-stage filtration on the collected cleaning waste liquid, and then the cleaning clear liquid after the three-stage filtration is refluxed into two groups of liquid storage pots 106 through two reflux pipes 17, so as to recycle the cleaning liquid, and the stubborn attachments on the conveyor belt 86 and the residual cleaning liquid are scraped off by the scrapers 20 on the two groups of collecting racks 4. After a period of time, the two groups of blocking cover plates 19 are opened to uniformly clean the two groups of collecting racks 4 through the cleaning windows; When it is necessary to move the conveyor frame 1 as a whole, first control the double-headed motor 71 to be in the closed state, and control the double-headed cylinder 121 to start to move the two sets of driving circular gears 122 outward to the meshing portion of the two sets of main circular gears 91. Then, according to the current displacement demand, if there is no beef on the conveyor belt 86, first control one of the second electric push rods 125 to start and drive the driven bevel gear 124 to move inward to the meshing portion of the driving bevel gear 123, and then control the double-headed motor 71 to start and drive the two sets of driving circular gears 122 to rotate through the two sets of main circular gears 91 that are meshed in place. 2 drives the driving bevel gear 123 on the double-headed cylinder 121 to rotate accordingly, and the meshed driving bevel gear 123 drives the second electric push rod 125 and the rotating rod 126 on one set of the driven bevel gears 124 to rotate accordingly, and the rotating rod 126 drives the main differential gear 132 to rotate accordingly, and the main differential gear 132 drives the rotating shaft 134 on the slave differential gear 133 to rotate accordingly, and the supporting bracket 131 plays a role in rotation support for the front drive wheel 135 and the rear drive wheel 136, then the rotating shaft 134 drives the front drive wheel 135 or the rear drive wheel 136 to rotate separately, and the other set is the auxiliary At this time, the conveyor rack 1 without beef chunks on the conveyor belt 86 is subjected to real-time dual-drive displacement. When there are still beef chunks on the conveyor belt 86, increasing the overall weight of the conveyor rack 1, the double-headed cylinder 121 and the two second electric push rods 125 are successively controlled to open, and then the two sets of driven bevel gears 124 move inward to the meshing portion of the driving bevel gear 123. Similarly, the two sets of main circular gears 91 and the two sets of driving circular gears 122 successively drive the rotating rods 126 on the two sets of driven bevel gears 124 to rotate through the driving bevel gear 123, and the main differential gears 132 on the two rotating rods 126 are driven by the two sets of main circular gears 91 and the two sets of driving circular gears 122. The rotating shaft 134 on the differential gear 133 drives the front drive wheel 135 and the rear drive wheel 136 of the two rotating shafts 134 to rotate in four-wheel drive, and the conveyor rack 1 with beef chunks on the conveyor belt 86 is displaced in real time in four-wheel drive. When the conveyor rack 1 is displaced into place, the double-headed motor 71 is first controlled to be closed, and then the double-headed cylinder 121 is successively controlled to be closed and the two sets of driving circular gears 122 are moved inwardly to disengage the meshing portion of the two sets of main circular gears 91 to the initial position. At the same time, one or two of the second electric push rods 125 are controlled to be closed and drive the driven bevel gear 124 to move outwardly to disengage the meshing portion of the driving bevel gear 123 to the initial position.
