3. A robust cold air blower for installation in a refrigerated food production plant according to claim 1 wherein the support assembly comprises a main support bar (3), the main support bar (3) being fixed at both ends to the first frame (2) and to the fixed angle iron (5) respectively, and the main support bar (3) being rotatably connected at its inner side to an auxiliary support bar (6) connected to the fixed angle iron (5).

4. A method of installing a robust cold air blower for installation in a refrigerated food production plant according to any one of claims 1 to 3 comprising the steps of:

s1, welding the fixed angle iron (5) below the second frame (4), and fixing the fixed angle iron (5) in the wall by adopting expansion bolts;

s2, taking out the first frame (2), attaching the first tenon block (12) at the end of the first frame to the second tenon block (14) at the end of the second frame (4), wherein when the first tenon block and the second tenon block are attached, the limiting block B (33) corresponds to the limiting groove B (34), the limiting block A (29) corresponds to the limiting groove A (30), and the second tenon block (14) is further laterally slid, so that the limiting block B (33) and the limiting block A (29) slide into the limiting groove B (34) and the limiting groove A (30) respectively;

s3, the screw rod (39) is rotated anticlockwise to enable the whole screw rod to move upwards through the internal thread of the sleeve (35) through the thread characteristic, one end of the movable rod (40) is further driven to rise, the other end of the movable rod (40) drives the bayonet lock (43) to move downwards through the rotation point of the screw rod and the fixed rod (37) as a fulcrum by utilizing the seesaw principle until the bayonet lock (43) is inserted into the through hole in the surface of the first tenon block (12), locking is completed, when the movable rod is disassembled, the screw rod (39) is rotated clockwise to enable the screw rod (39) to move downwards along the direction of the internal thread, one end of the movable rod (40) is driven to move downwards, and then the other end of the movable rod (40) can tilt upwards, so that the bayonet lock (43) moves out of the through hole, and the disassembly is completed;

s4, taking out the reinforcing bottom plate (8), inserting one end with the first inserting block (10) into the slot (9), further taking out the pin block (18), inserting the pin block (18) into the sliding groove (20), pressing the sliding button (24) with hands during insertion and dragging backwards along the direction of the sliding rail (23), driving the movable sleeve (48) to displace along the guide rod (46) through the connecting strip after dragging the sliding button (24) and pressing the first spring (47), further driving the L-shaped rod (44) to move out of the sliding groove (20), inserting the pin block (18) at the moment, further pushing the pin block (18) to displace in the sliding groove (20) until the pin shaft (11) is inserted into the pin hole (17), loosening the sliding button (24) after the second clamping block (21) is clamped with the first clamping block (19), driving the L-shaped rod (44) to be inserted into the sliding groove (20) again under the tension of the first spring (47) and to be jointed with the side wall of the second clamping block (21), further pressing the second inserting block (15) by hands to enable the second inserting block to retract into the second cavity (49), then pressing the reinforcing bottom plate (8) downwards to enable the second inserting block (15) to move to a socket on the inner side of the second frame (4), and driving the second inserting block (15) to extend into the socket under the action of a second spring (50) to complete the integral assembly of the reinforcing bottom plate (8);

s5, taking out the main supporting rod (3), fixing two ends of the main supporting rod (3) to the outer side of the first frame (2) and the outer side of the fixed angle iron (5) through bolts respectively, further rotating the auxiliary supporting rod (6), and fixing the other end of the auxiliary supporting rod (6) to the inner side of the fixed angle iron (5) through bolts;

s6, placing the air cooler (1) on the assembled mounting bracket, ensuring that the connecting hole at the bottom of the air cooler corresponds to the mounting hole (7), and further fixing the air cooler through a fastening bolt to complete the whole set of assembly.
