[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1 , Figure 2 , Figure 3As shown, a tar slag box device convenient for unloading includes a tar slag box 1, a platform 2, an exhaust hood 3, a top plate 4, a winch 5, a column 6, and a PLC controller 7. The cross section of the tar slag box 1 is "V"-shaped. A screw conveyor 8 is fixed at the bottom of the tar slag box 1. The top outlet of the screw conveyor 8 is connected with the bottom of the tar slag box 1. The tar slag enters the screw conveyor 8 downward in the tar slag box 1 and is sent out by the screw conveyor 8. A pair of square pipes 9 are fixed at the bottom of the screw conveyor 8. The square pipes 9 are used to be inserted by the front fork of a forklift so that the forklift can lift the tar slag box 1 and the screw conveyor 8.

[0020] The platform 2, the exhaust hood 3, the top plate 4 and the winch 5 are arranged in sequence from bottom to top, a pair of columns 6 are fixed at both ends of the platform 2, a material leakage port 10 is arranged at one end of the platform 2, a pressure plate 11 is embedded in the top of the platform 2, a pressure sensor 12 is arranged at the bottom of the pressure plate 11, the tar slag box 1, the screw conveyor 8 and the square tube 9 are movably placed above the pressure plate 11, and the bottom of the square tube 9 contacts the top of the pressure plate 11. The tar slag box 1, the screw conveyor 8 and the square tube 9 need to be placed on the pressure plate 11 so that the pressure sensor 12 senses the preset weight, the outlet of the screw conveyor 8 corresponds to the material leakage port 10, and the tar slag discharged from the outlet of the screw conveyor 8 falls from the material leakage port 10 to complete the unloading;

[0021] Sleeves 13 are fixed on both sides of the exhaust hood 3, and the sleeves 13 are slidably sleeved on the pillars 6. The bottom movable cover of the exhaust hood 3 is arranged on the top of the tar slag box 1. The exhaust hood 3 slides on the pillars 6 through the sleeves 13 to achieve lifting. A negative pressure pipe 14 is provided on the top of the exhaust hood 3. The negative pressure pipe 14 can be connected to the exhaust fan or the factory's dust removal negative pressure main pipe through a corrugated pipe to discharge the tar slag odor;

[0022] The top plate 4 is fixed between the tops of a pair of columns 6, and the winch 5 is fixed on the top of the top plate 4. A through hole 15 is provided on the top plate 4. The rope of the winch 5 passes through the through hole 15 and is fixed to the top of the exhaust hood 3. The rope of the winch 5 lifts or lowers the exhaust hood 3.

[0023] The signal output end of the pressure sensor 12 is connected to the signal input end of the PLC controller 7, and the PLC controller 7 is electrically connected to the winch 5. The PLC controller 7 presets the upper and lower limit values ​​of the weight. The weight of the empty tar slag box 1, the screw conveyor 8 and the square tube 9 is lower than the lower limit value. When the tar slag box 1 is fully filled with tar slag, its weight must be higher than the upper limit value. The pressure sensor 12 senses that the weight is higher than the upper limit value and gives a signal to the PLC controller 7, so that the control instruction of the PLC controller 7 is given to the winch 5, and the winch 5 is lowered so that the exhaust hood 3 covers the top of the tar slag box 1; the tar slag box 1, the screw conveyor 8 and the square tube 9 are not effectively placed on the pressure plate 11, and are not fully sensed by the pressure sensor 12. Their weight is between the upper and lower limit values ​​and no signal is given to the PLC controller 7.

[0024] It also includes a warning light 16, which is electrically connected to the PLC controller 7. The pressure sensor 12 senses a value higher than the upper limit, indicating that the tar slag box 1, the screw conveyor 8 and the square tube 9 are all placed on the pressure plate 11. A signal is given to the PLC controller 7, so that the control instruction of the PLC controller 7 is first given to the warning light 16. The warning light 16 lights up, prompting the worker to put them in place. The signal from the PLC controller 7 causes the control instruction of the PLC controller 7 to be given to the winch 5, and the winch 5 is lowered.

[0025] Working principle: When the utility model is in use, the front fork of the forklift is inserted into the square tube 9, and the fully loaded tar slag box 1 and the screw conveyor 8 are lifted to the pressure plate 11 of the platform 2. The pressure sensor 12 senses that the weight is higher than the preset upper limit value, and the warning light 16 lights up and is put in place. The outlet of the screw conveyor 8 also corresponds to the leakage port 10. Then the rope of the winch 5 lowers the exhaust hood 3 to cover the top of the tar slag box 1, and the screw conveyor 8 is turned on to discharge the tar slag. At the same time, the exhaust hood 3 is used to discharge the odor of the tar slag.

[0026] On the contrary, after the tar slag box 1 is emptied, the pressure sensor 12 senses a value lower than the lower limit, the rope of the winch 5 lifts the exhaust hood 3, the front fork of the forklift is inserted into the square tube 9, and the empty tar slag box 1 and the screw conveyor 8 are lifted away.

[0027] The present application only requires the tar slag box 1 to be transported to the platform 2 by a forklift, and the exhaust hood 3 can be automatically installed. The screw conveyor 8 can be used to discharge the tar slag and absorb the odor at the same time. The slag unloading operation is simple and does not require manual labor, which reduces labor intensity and also reduces odor.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
