The top cover is arranged at the upper end of the material guiding box. The top cover adopts an open structure, and a feeding pipe is formed in the middle of the upper end of the top cover. The beneficial effects are as follows: Through the design of the bottom-opening top cover, the utility model effectively reduces the escape of raw material odor during the production of vehicle urea, reduces the harm to the health of workers caused by raw material volatilization, and improves the safety of the feeding process. Through the design of the transparent telescopic pipe, the discharging end of the device can extend into the feeding port of the mixing tank for the production of vehicle urea according to actual feeding needs, effectively avoiding the leakage of raw materials due to the gap between the discharging end of the device and the vehicle urea mixing pipe during the feeding process, avoiding the waste of raw materials, and having good practicability.

[0004] During the use of this patent, the problem of vehicle urea raw material volatilization is reduced by narrowing the feeding port, but it brings inconvenience to the work of adding vehicle urea raw materials, and there is a lack of quantitative feeding function during feeding, which affects the quality of product production.

[0005] Therefore, a feeding device for the production of vehicle urea solution is proposed to solve the above problems. Summary of the Utility Model

[0028] Specifically: The weight increasing plate 101 increases the counterweight to prevent the installation housing 1 from tilting towards the material conveying pipe 401 during material conveying. The installation ring 102 and the bolt holes 103 facilitate the installation of the sealing ring 202 and the bolt holes 203. The installation groove 104 facilitates the installation of the material conveying pipe 401. The storage bin 105 stores raw materials inside, and the connecting steel pipe 106 connects the storage bin 105 and the material conveying pipe 401.

[0029] In one embodiment, the bin cover assembly 2 includes a feeding hopper 201, a sealing ring 202 is fixedly sleeved on the surface of the feeding hopper 201, and a plurality of bolt holes 203 are circumferentially formed on the surface of the sealing ring 202.

[0030] Specifically: The upper port of the feeding hopper 201 has a large diameter, which is convenient for adding raw materials, and the lower port has a small diameter, which reduces the volatilization of odor.

[0031] In one embodiment, the bottom of the feeding hopper 201 is movably located inside the storage bin 105, the sealing ring 202 is installed on the surface of the installation ring 102, a plurality of bolt holes 203 communicate with a plurality of bolt holes 103 correspondingly, and the interiors of the plurality of bolt holes 203 and the plurality of bolt holes 103 are respectively connected by bolts.

[0032] Specifically: The sealing ring 202 and the mounting ring 102 are fixedly connected by installing bolts inside the bolt hole two 203 and the bolt hole one 103.

[0033] In one embodiment, the weighing device 3 includes a limiting groove 301. The inner side of the limiting groove 301 is movably sleeved on the bottom side of the surface of the mounting housing 1. A weighing sensor 302 is fixedly installed on the bottom side inside the limiting groove 301. Four telescopic rods 303 are fixedly installed at the four ends of the bottom side inside the limiting groove 301. The top ends of the weighing sensor 302 and the four telescopic rods 303 are fixedly connected to the bottom of the mounting housing 1.

[0034] Specifically: The inner wall of the limiting groove 301 fits against the bottom of the surface of the mounting housing 1 to limit the mounting housing 1. The weighing sensor 302 is electrically connected to an external control panel, and measures the weight applied by the mounting housing 1 in real time and transmits it to the external control panel. The telescopic rods 303 play a role in limiting and supporting the mounting housing 1.

[0035] In one embodiment, the feeding device 4 includes a feeding pipe 401. One end of the feeding pipe 401 is fixedly installed with a motor 402. The output end of the motor 402 is installed with a transmission rod 403 through the surface of the feeding pipe 401 by means of a bearing. One end of the transmission rod 403 is installed on one side inside the feeding pipe 401 by means of a bearing. A screw blade 404 is fixedly installed on the surface of the transmission rod 403. One end of the surface of the feeding pipe 401 is penetrated and installed with a discharge pipe 405.

[0036] Specifically: After the motor 402 is started, the raw materials are conveyed to an external stirring device through the transmission rod 403 and the screw blade 404 through the discharge pipe 405. The discharge pipe 405 should be connected to an external stirring device for producing vehicle urea solution or be located above the inside of an external stirring device for producing vehicle urea solution.

[0037] In one embodiment, the other end of the surface of the feeding pipe 401 is penetrated and connected to the bottom of the connecting steel pipe 106.

[0038] Specifically: The raw materials in the storage bin 105 fall into the feeding pipe 401 through the connecting steel pipe 106.

[0039] Working principle: A feeding hopper 201 is installed at the top of the storage bin 105. The feeding hopper 201 is funnel-shaped. Bolts are installed in the second bolt hole 203 and the first bolt hole 103 to fixedly install the feeding hopper 201. During the production operation of vehicle urea solution, when it is necessary to feed the raw materials for vehicle urea production, pour them from the upper end of the feeding hopper 201, and they will fall into the storage bin 105 through the bottom of the feeding hopper 201. The outlet diameter at the bottom of the feeding hopper 201 is relatively small, which can reduce the odor generated by the volatilization of the raw materials used in vehicle urea production during transportation. At the same time, the diameter at the top is relatively large, which is convenient for the addition of vehicle urea raw materials; in this device, the weighing sensor 302 is connected to an external control panel. After the vehicle urea raw materials are added to the storage bin 105, the overall weight of the installation housing 1 and its connecting devices will be measured by the weighing sensor 302. After setting the feeding parameters required for production through the external panel, the external control panel will start the motor 402. The motor 402 drives the transmission rod 403 and the auger blade 404 to rotate. The vehicle urea raw materials inside the storage bin 105 enter the inside of the conveying pipe 401 through the connecting steel pipe 106 and are carried to the discharge pipe 405 by the rotation of the auger blade 404 and then fall into an external stirring device for the next production work. As the vehicle urea raw materials are conveyed, when the weight measured by the weighing sensor 302 decreases to the set weight, the external control panel will shut down the motor 402 and stop the raw material conveying. In this way, the quantitative feeding of vehicle urea raw materials is improved, thereby improving the production quality.
