TECHNICAL FIELD

[0001] The utility model relates to the technical field of unloader, concretely to a novel unloader. BACKGROUND

[0002] The unloader is the main equipment for dust removal, air supply and other equipment feeding, and is suitable for powdery materials and granular materials. For example, the Chinese utility model patent with the publication number CN216471042U discloses a special unloader for powder, which allows the materials in the upper bin to fall by gravity and fill in the gap between the impellers, and then be discharged from the lower discharge port through the rotation of the impellers to realize quantitative unloading. However, the traditional unloader also often uses a gate valve to control the quantitative unloading.

[0003] However, the bottom of the bin of the previous unloader is mostly conical in structure. When the bin is filled with humid air or the materials are intermittently discharged and accumulated, it is easy to cause the powdery materials or granular materials to be hardened during the discharging process, thereby affecting the subsequent quantitative unloading operation. SUMMARY

[0004] Therefore, the utility model aims to provide a novel unloader to solve the technical problems mentioned in the prior art.

[0005] A novel unloader includes a bin, which comprises an inlet portion and a conical discharging portion connected from top to bottom. The conical discharging portion is provided with a material loosening assembly, which comprises:

[0008] At least two groups of material scraping plates are installed on the two ends of the connecting rod and are in close contact with the inner wall of the conical discharging portion. The drive rod drives the material scraping plates to move and loosen the hardened materials in the conical discharging portion of the bin.

[0009] Optionally, the material loosening assembly further includes a gas blowing cylinder, which is installed on the end of the drive rod and is arranged between the two groups of material scraping plates. The gas blowing cylinder includes:

[0010] A fixed tube is arranged in the conical discharging portion of the bin, one end of which penetrates the conical discharging portion of the bin and extends to the outside of the bin, where a dry air input source is arranged.

[0011] A movable sleeve is slidably connected with the fixed tube at one end of the driving rod and at the other end of the driving rod.

[0012] The fixed tube and the movable sleeve are respectively provided with control valves at their ends away from each other.

[0013] The control valve at one end of the fixed tube is opened to access dry air when the blowing cylinder is stretched.

[0014] The control valve at one end of the movable sleeve is opened to blow the dry air accessed in the blowing cylinder into the conical discharging part of the stock bin to loosen the compacted material.

[0015] Optionally, a uniform air cover is mounted on the outer periphery of the movable sleeve and covers one side of the air outlet of the movable sleeve to uniformly distribute the flow direction of the dry air on the outer periphery of the movable sleeve.

[0016] Optionally, the control valve is a one-way valve.

[0017] Optionally, the linear displacement of the movable sleeve is half the length of the conical discharging part of the stock bin.

[0018] Optionally, the two groups of scraping plates on the same side of the connecting rod are connected by an auxiliary connecting rod.

[0019] Optionally, the driving rod is provided with a power unit outside the stock bin.

[0020] Optionally, the power unit is any one of a handle, an air cylinder or a hydraulic cylinder.

[0021] The beneficial effects of the present application include:

[0022] 1. The novel unloader provided by the present application is provided with a material loosening assembly in the conical discharging part of the stock bin, so that the scraping plate is driven to move by the driving rod to loosen the compacted material in the conical discharging part of the stock bin, thereby ensuring smooth discharging of the material by gravity and avoiding affecting the subsequent quantitative discharging operation.

[0023] 2. The novel unloader provided by the present application is provided with a blowing cylinder and is configured with a dry air input source, which is used to open the control valve at one end of the fixed tube to access dry air when the blowing cylinder is stretched, and is used to open the control valve at one end of the movable sleeve to blow the dry air accessed in the blowing cylinder into the conical discharging part of the stock bin to loosen the compacted material again when the blowing cylinder is compressed, thereby further improving the loosening effect of the material.

[0030] In the above, as Figure 1As shown, the driving rod 2 is located outside the bunker 1 and is provided with a power unit 11, wherein the power unit 11 is arranged as any one of a handle, a pneumatic cylinder or a hydraulic cylinder; the driving rod 2 can be configured with an automatic or manual driving mode according to the use environment of the bunker 1 to drive the driving rod 2 to move, thereby realizing the loosening operation of the material. Specifically, when the material is frequently hardened, the automatic driving mode can be selected to drive the loosening assembly to run at least once before each unloading operation to ensure the smooth unloading of the material; when the material is relatively less hardened, the manual driving mode can be selected to drive the loosening assembly to run regularly according to the actual use or when the hardening occurs, thereby reducing the use cost, and the handle is helpful for the operator to operate.

[0031] Further, as shown in Figure 2 and Figure 3 , the loosening assembly further comprises a blowing cylinder, the blowing cylinder is installed at the end of the driving rod 2 and is arranged between the two groups of material scraping plates 4, and the blowing cylinder comprises a fixed pipe 5 and a movable sleeve pipe 6 which are slidably connected with each other; specifically, the fixed pipe 5 is arranged in the conical discharging part of the bunker 1, one end of the fixed pipe 5 penetrates the conical discharging part of the bunker 1 and extends to the outside of the bunker 1 to be provided with a dry air input source 7; one end of the movable sleeve pipe 6 is installed at the end of the driving rod 2, and the other end of the movable sleeve pipe 6 is slidably connected with the fixed pipe 5; the ends of the fixed pipe 5 and the movable sleeve pipe 6 away from each other are respectively provided with control valves 8; when the blowing cylinder is stretched, the control valve 8 at one end of the fixed pipe 5 is opened to access the dry air; when the blowing cylinder is compressed, the control valve 8 at one end of the movable sleeve pipe 6 is opened to blow the dry air accessed in the blowing cylinder into the conical discharging part of the bunker 1 to loosen the hardened material again, thereby further improving the loosening effect of the material.

It should be noted that the dry air sent by the dry air input source 7 can be treated by high pressure and high temperature, so as to evaporate the humid air when the dry air is sent into the bunker 1, thereby further preventing the material in the bunker 1 from being hardened.

[0033] Further, the linear displacement amount of the movable sleeve 6 is set as half of the length of the conical discharging part of the bin 1 to ensure the effective movement stroke of the movable sleeve 6. Meanwhile, the two groups of material scraping plates 4 are arranged on the same side of the connecting rod 3, and the two groups of material scraping plates 4 are respectively arranged at the two ends of the movable sleeve 6 and connected through the auxiliary connecting rod 10, so that when the movable sleeve 6 moves, the material scraping plates 4 can be ensured to contact the inner wall of the bin 1 and the side away from the power unit 11, so that the material scraping plates 4 can drive the material accumulated in the bin 1 to impact on the inner side wall of the conical discharging part after being broken, so as to shake off the broken material. In the above, as shown in Figure 2 the connecting rod 3 is arranged in a rhombus structure, which can extrude and break the blocky and consolidated material through the edges of the connecting rod 3 when the material loosening assembly operates.
