In the initial state, the telescopic air rod 20 is in the longest state, the first rotating plate 30 and the second rotating plate 23 are in the same plane, the supporting platform 37 is located at the uppermost side under the elastic force of the first spring 35, the top rod 34 is located at the uppermost side under the elastic force of the second spring 17, the push plate 39 is located at the leftmost side, and the contact block 64 is not in contact with the first conductive strip 67 and the second conductive strip 65.

When the goods are required to be loaded, placing the cement bag on the upper side of the conveyor belt 26, starting the second motor 31, further rotating the second rotating shaft 71 and driving the first chain wheel cylinder 46 to rotate, further moving the chain 25 and driving the conveyor belt 26 to move, and further driving the cement bag to be conveyed upwards;

then the cement bag falls on the supporting platform 37, and because the supporting platform 37 is inclined to the right, the cement bag will not fall off the supporting platform 37, and then the supporting platform 37 moves downwards under the gravity of the cement bag, the paper box supporting platform 37 moves to the lowest side, and then the supporting platform 37 presses downwards to push the push rod 34, and then the push rod 34 moves downwards and contacts with the first electric wire 15, and then the circuit of the first electric wire 15 is connected, and then the first motor 14 is powered on, and then the first rotating shaft 44 rotates and drives the belt 13 to move to the left side through the first belt wheel 11, and because the cement bag is at the lowest side, the left end of the cement bag will rest on the upper side of the belt 13, and because the upper side of the supporting platform 37 is provided with the roller 41, and then the belt 13 will drive the stacked cement bag to move to the left side until the cement bag moves out of the supporting platform 37, then the supporting platform 37 will move to the highest side again under the elasticity of the first, the push rod 34 moves to the uppermost side under the elastic force of the second spring 17, and in the moving process of the push rod 34, the cement bag is driven by the belt 13 to move left, the right end part of the belt 13 is left to be free, so that the next round of transportation is facilitated, when the push rod 34 moves to the uppermost side, the first motor 14 is turned off, the belt 13 stops moving, and the loading operation of one round is completed until the transport vehicle is filled;

then the air pump 18 is started and the telescopic air rod 20 is contracted, so that the first rotating plate 30 is turned downwards, meanwhile, the first pull rope 29 is pulled tightly, so that the second rotating plate 23 is bent upwards until the right-angle relation with the first rotating plate 30 is kept, at the moment, the first rotating plate 30 is in a vertical state, the second rotating plate 23 is in a horizontal state, and the conveyor belt 26 is always tightly attached to the first rotating plate 30 and the second rotating plate 23 due to the compression effect of the pressure plate 27;

when unloading is needed, the third motor 55 is started, the fourth rotating shaft 53 rotates and drives the cylinder 61 to rotate, the sliding rod 59 is driven to move left and right through the rail groove 62, and the push rod 60 moves left and right and drives the push plate 39 to move left and right in a reciprocating manner;

the rotation of the fourth shaft 53 will drive the first gear 54 to rotate, and then the second gear 57 will drive the fifth shaft 56 to rotate, and then the rotation block 69 will rotate and drive the contact block 64 to rotate, the first motor 14 is then adjusted to reverse mode, while the contact block 64 will contact the first conductive strip 67, and the circuit where the second electric wire 68 is located is turned on, and the electromagnet 33 attracts the support platform 37 to the lowermost side toward the lower side, then the first motor 14 is started again and drives the cement bags to move to the right gradually until the cement bags all move to the upper side of the supporting platform 37, the contact block 64 will then disengage from the first conducting strip 67 and contact the second conducting strip 65, whereupon the electromagnet 33 repels the support platform 37 and pushes the support platform 37 upwards a distance, while the push plate 39 just pushes the uppermost cement bag to the right, further pushing the cement bag onto the conveyor belt 26, then starting the second motor 31 and transporting the cement bag down by the conveyor belt 26;

meanwhile, after the cement bag at the top is pushed out, the weight of the supporting platform 37 is reduced, so that the supporting platform 37 moves upwards continuously, and the repulsion force is smaller because the distance from the electromagnet 33 is farther, so that the supporting platform 37 gradually moves upwards and the cement bag at the top can be pushed out to the right side by the push plate 39 all the time until the cement bags are all discharged, a round of discharging circulation is completed, then the contact piece 64 contacts the first conductive strip 67 again, and the discharging operation of the second round is started until the cement bags are all discharged.

The invention has the beneficial effects that: inside can be very light transporting the storage space with the cement bag, and there is the conveyer belt to transport the cement bag on the supporting platform can be automatic pile up until extrudeing supporting platform to downside, then first motor will automatic start and will pile up the cement bag transportation to the left side, accomplish a round of loading operation until filling up whole storage space, and also can transport the cement bag in order during the discharge, it is very convenient to use, low in labor strength, and the handling efficiency is high, the time of workman direct contact cement bag is few simultaneously, the condition that all is cement powder when having avoided the conventional transport water bag of workman throughout the whole body, cement workman's healthy operational environment has been guaranteed.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
