The specific implementation is as follows:

First, use a gantry crane to load the material to be transported into the bucket, then lift it up, and open the dust cover 221 on the feeding pipe 22. The dust cover 221 has a dust-proof effect when not in use, and the dust cover 221 is clipped. The top of the feeding pipe 22 can be opened and fixed easily, and the dustproof cap 231 on the ventilation pipe 23 is also opened simultaneously, and the dustproof cap 231 is sleeved on the ventilation pipe 23, which can be easily removed and installed.

After the dustproof cover 221 is opened, the person standing on the housing 21 communicates with the person driving the gantry crane to place the bucket in a suitable position. There are two hooks on the gantry crane, one to maintain the balance of the bucket, and the other to tilt the bucket , while the bucket is tilted, the material in the bucket is poured into the feeding pipe 22, and then enters the feeding bin 2.

The gantry crane transports two kinds of materials. The first kind of material enters the first set of unloading bins 2. The lower part of the unloading pipe 22 is provided with a dust-proof unloading device 26. In bin 2, because the material is easy to condense into blocks in this way, it is not easy to unload.

The dust-proof blanking device 26 at the lower part of the blanking tube 22 is closed under the gravity of the upper counterweight 264 when the balance platform 262 is closed. On the platform 262, when the amount of material poured into the balance platform 262 is large, when the downward gravity generated by the upper counterweight 264 and the upper screw rod 263 is smaller than the downward force of the material and the balance platform 262, the two balance platforms 262 will be opened.

The balance table 262 will continue to close after the material is loaded, and a small part of the material is stuck on the balance table 262, and the dust cannot be scattered. Since the gantry crane is cyclically feeding different feeding bins 2, this will prevent dust. effect, and at the same time, it can ensure that the amount of blanking is sufficient.

After the material falls from the balance platform 262, it will enter the lower bin 2. The material in the first group of lower bins 2 is easy to condense after accumulation. A screw feeding device 27 is provided in the lower bin 2. After the motor 271 works, the transmission rod 272 is driven to rotate, and the power on the transmission rod 272 drives the feeding rod 274 to rotate after the commutator 273 changes directions.

The agitating blade 275 on the upper part of the feeding rod 274 stirs the material to make the material move, and the moving material continuously enters the conical spiral blade 276, which is compatible with the inner wall of the lower material bin 2, and the conical spiral The blade 276 rotates and conveys the material slowly under the box. At this moment, the material can be partly coagulated due to extruding.

After the material falls from the lower silo 2, it enters the screw conveying device 31. A flange 29 is connected between the screw conveying device 31 and the lower hopper 2, and the flange 29 effectively fixes the two. The lower part of the flange 29 is provided with a The adjustment device 28 can rotate the adjustment plate 282 by turning the adjustment handle 283, and the amount of material to be cut will be reduced or increased while rotating. The adjustment rod 281 is threaded in the support seat 11, which is more convenient to rotate.

Driven by the conveying motor 311, the screw conveying device 31 conveys the material entering it forward, and when it is conveyed to the front, it is then discharged through the discharge port of the shell 312, and the material is discharged from the spiral conveying device 31 and then passes through The feed port 411 enters the auxiliary material bin 4 , in this state the material is airtight and will not fly, and the auxiliary material bin 4 is provided with a screening device 42 inside.

After the material enters the auxiliary material bin 4, it will enter the screen 422 of the screening device 42. The vibration motor 421 on the side wall of the auxiliary material bin 4 starts to work, and the vibration of the vibration motor 421 drives the material in the screen 422 to roll continuously. The small and medium materials keep falling, while the large materials stay in the auxiliary material bin 4. After the auxiliary material bin 4 is loaded, the hasp 424 can be opened first, and then the pull ring 425 is pulled to pull out the screen 422 and clean it up. .

After cleaning, push inward through the pull ring 425, and then buckle the hasp 424 after pushing in, and fix the screening device 42, so that cleaning and fixing are very convenient. Port 414, can carry out regular maintenance.

After the material is screened, it flows out from the circular discharge pipe 412 and flows into the receiving tank 432 of the sealed feeding device 43. The receiving tank 432 is horizontal under the gravity of the lower balance bar 431, and the two receiving tanks 432 are closely connected at this moment. Fitting, after the material enters the material receiving trough 432, due to the sealing of the material receiving trough 432, it can prevent the materials in the material receiving trough 432 from flying everywhere, causing waste of materials, and the flying materials are extremely difficult to clean up because they are scattered everywhere. The groove 432 can effectively avoid this situation.

When the material accumulates a certain amount in the material receiving trough 432, the material receiving trough 432 will rotate and open to both sides at the same time, so that the material in the material receiving trough 432 can fall to the discharge conveying device under the situation of raising little dust 5 or more.

The remaining unloading bin 2 will load the second material. After unloading, it enters the material receiving pipe of the airtight conveying device 32, and then falls onto the dust protection belt 3242. The two sides of the dust protection belt 3242 are fixed with repeated folding The protective plate 3243 can prevent the material from rolling out of the dust protection belt 3242. When the weight of the material is sufficient, the transmission device 324 works, and the drum 54 rotating drum 3241 drives the material on the dust protection belt 3242 to be transported forward.

The both sides of cylinder 54 are provided with adjusting assembly 325, and the two ends of transmission rod 326 are fixedly arranged in the connecting hole of slide block 3252, when dust protection band 3242 is loose, the nut 3254 on the fastening screw rod 3253 is unscrewed, and then Rotate tightening screw mandrel 3253, because tightening screw mandrel 3253 is threadedly connected with sliding block 3252, sliding block 3252 can move outwards, and dust protection band 3242 is tensioned again.

The upper part of the closed shell 322 is provided with a ventilation pipe 3222, which can replace the air in the transmission device 324 in time. After the material is transported by the dust protection belt 3242, it falls from the material removal pipe 3223 and falls into the auxiliary material bin 4 below. After passing through the auxiliary material bin 4, the material will enter the sealed feeding device 43. After the material in the sealed feeding device 43 has accumulated to a certain amount, the receiving tank 432 is opened, and the material falls onto the discharging conveying device 5.

Two kinds of materials can all fall on it along with the non-stop movement of conveyor belt 55, and the support device 56 on the both sides of support conveyor belt 55 is for inclined setting, and the rotating roller 562 plays the effect of support when not working, when working When rotating roller 562 has the rotation of conveyer belt 55 and rotates together, plays the effect of reducing friction.

The conveyor belt 55 will become V-shaped like this, and the conveyor belt 55 will accumulate the material in the middle of the conveyor belt 55 when transporting the material like this, and it is difficult to have the material spill out. The working principle of the tensioning assembly 57 is the same as that of the adjusting assembly 325, and it can be tensioned in time after the conveyor belt 55 is relaxed, and the conveyor belt 55 drives the material to be transported to other devices.

This specific embodiment is only an explanation of the utility model, and it is not a limitation of the utility model. After reading this description, those skilled in the art can make modifications to the embodiment without creative contribution according to needs, but as long as it is within the utility model All new claims are protected by patent law.
