Before the preparation, the whole hopper is manually installed at the discharge port of the salt conveyer belt through the screw hole at the upper side of the side baffle disc 202, after the installation is completed, the salt conveyer belt starts to convey salt into the semicircular hopper 201, when the conveying amount of the salt is small, the salt is automatically conveyed into the next device from the discharge port arranged at the lower side of the semicircular hopper 201, along with the expansion of the conveying amount of the salt, the size of the discharge port at the lower side of the semicircular hopper 201 needs to be changed along with the change of the conveying amount of the salt, so that the salt is prevented from being blocked inside the semicircular hopper 201, in the conveying process of the salt, after the salt falls on the material collecting plate 208, under the action of the gravity of the salt, the adjustable material discharging plate 207 rotates around the torsion spring rotating shaft through the material collecting plate 208, namely, the adjustable material discharging plate 207 rotates clockwise when the salt is viewed from left to right, and the rotating angle is changed along with the gravity applied by the salt, that is, as the salt conveying amount changes, as the angle of the adjustable blanking plate 207 changes, the space between the adjustable blanking plate 207 and the semicircular hopper 201 through which the salt can pass also changes, meanwhile, as the angle of the adjustable blanking plate 207 changes, the adjustable blanking plate 207 simultaneously drives the two connecting frames 209 to rotate clockwise, and further drives the adjusting plate 2010 to rotate clockwise through the two connecting frames 209, that is, the adjusting plate 2010 is driven to slide into the semicircular hopper 201, so that the discharge port on the lower side of the semicircular hopper 201 is increased, that is, the discharge rate of the semicircular hopper 201 can be increased along with the increase of the salt conveying amount, and further salt is prevented from being blocked at the bottom of the semicircular hopper 201, and as the two guide plates 2011 are arc-shaped, salt is further prevented from being blocked at the bottom of the semicircular hopper 201, when the salt falls on the material collecting plate 208, because the inclined convex blocks are arranged on the surface of the material gathering plate 208, after the salt falls on the surface of the material gathering plate, the salt is prevented from being obviously rebounded by the inclined convex blocks, so that the salt scatters around, meanwhile, because the material gathering plate 208 is concave, the salt can be accumulated towards the middle of the material gathering plate 208, namely, the salt is gathered, meanwhile, in the salt conveying process, in order to prevent a large amount of salt from falling on the rear side of the upper surface of the adjustable blanking plate 207, the angle change of the adjustable blanking plate 207 along with the change of the salt conveying amount cannot be caused, and the salt is prevented from splashing on the rear side of the upper surface of the adjustable blanking plate 207 by the isolation plate 303;

further, with the change of the angle of the adjustable blanking plate 207, the adjustable blanking plate 207 drives the primary splash-proof plate 203 to rotate, when the salt conveying capacity is large, the salt is prevented from splashing out of the semicircular hopper 201 through the primary splash-proof plate 203, when the salt conveying capacity reaches a maximum value, the salt is prevented from splashing out of the semicircular hopper 201 through the secondary splash-proof plate 205, and meanwhile, because the primary splash-proof plate 203 and the secondary splash-proof plate 205 are arc-shaped, the blocked salt can fall back into the semicircular hopper 201 for the second time;

when the output quantity of the salt is far larger than the derived quantity of the semicircular hopper 201, the salt can be blocked at the bottom of the semicircular hopper 201, along with the increase of the salt accumulation quantity at the bottom of the semicircular hopper 201, the pressure of the salt accumulated at the bottom of the semicircular hopper 201 on the two warping plates 405 is increased, on the basis of the front view and the back view, the left warping plate 405 rotates clockwise around the left sloping plate 204, the right warping plate 405 rotates anticlockwise around the right sloping plate 204, the two warping plates 405 drive the two U-shaped plates 406 through the connecting rods, then the two elastic members 407 are driven through the two U-shaped plates 406, then the two sliding blocks 409 are driven through the two elastic members 407, so that the two sliding blocks 409 slide upwards in the two sliding rails 408, the two elastic members 407 are stretched while sliding, the two sealing plates 4010 are driven to move upwards at the same time, and then the openings at the opposite sides of the two overflow racks 401 are gradually opened, when salt accumulates to the height of two overflow frame 401 bottom semi-circular hopper 201, in order to carry salt as early as possible, prevent the jam, and then make salt flow out from two overflow frame 401 automatically, and then play mediation overflow effect, prevent that the accumulation volume of salt in semi-circular hopper 201 bottom from continuing to increase, lead to equipment paralysed, after salt is dredged to accomplish in semi-circular hopper 201 bottom, under the effect of two elastic component 407 resilience forces, make two wanes 405 resume the normal position, even make two sealed closures 4010 close two overflow frame 401 once more.
