Description

Technical Field

[0001] The utility model relates to the technical field of brick making, and particularly relates to a bin with automatic start and stop. Background Art

[0002] In the process of brick production and manufacturing, brick raw materials need to be first placed in a bin and distributed to a cloth feeder through the bin. Then, the raw materials are output to a mold through the cloth feeder, and subsequently, the bricks can be fired. The raw materials are evenly stirred in a mixer, and the mixer transports the brick-making materials to the bin of the cloth feeder through a belt conveyor. The bin can automatically supplement the brick-making raw materials to the cloth feeder quantitatively, eliminating the need for manual raw material handling, effectively reducing the labor intensity of workers and improving the brick-making efficiency.

[0003] Although the above-mentioned prior art can solve corresponding technical problems, there are still certain defects: the inner cavity capacity of the existing bin is a certain value. Therefore, during the process of feeding raw materials into the bin, workers need to constantly monitor the amount of raw materials in the bin to prevent waste caused by excessive raw materials overflowing from the bin, which requires additional labor costs and has a low degree of automation and inconvenient use. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a bin with automatic start and stop, which has a high degree of automation and is convenient to use, aiming at the defects and deficiencies of the prior art.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions: a bin with automatic start and stop, including a hopper. A power connection frame is arranged at the top of the hopper, and a material level sensor is fixedly arranged on the top surface of the hopper. The material level sensor is electrically connected to the power connection frame. After the raw materials are piled up to a certain height in the hopper, the power connection frame is connected, enabling the material level sensor to be powered on and output a stop signal to the belt conveyor.

[0006] Further improvement: Reinforcing ribs are arranged in the middle section of the hopper.

[0007] Further improvement: The power connection frame includes a conductive plate embedded in the top of the hopper and a nylon rod arranged on one side of the conductive plate. A round steel column is slidably arranged up and down on the nylon rod. A first wire electrically connected to the material level sensor is arranged on the conductive plate, and a second wire electrically connected to the material level sensor is arranged at the top end of the round steel column.

[0008] Further improvement: Fixing bolts are also arranged on the conductive plate.

[0009] Further improvement: A bullet-shaped convex block is arranged at the bottom of the round steel column.

[0010] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: The present utility model is provided with a power connection frame above the hopper. When the raw materials are piled up to a certain height, the side of the raw materials contacts the conductive plate, and the top contacts the round steel column. Then, through the conductivity of the raw materials, the conductive plate and the round steel column cooperate with the first wire and the second wire to form a circuit, thereby turning on and starting the level sensor and outputting a stop signal to the belt conveyor. Thus, when the raw materials are full in the hopper, the conveying is automatically stopped, greatly improving the automation and making it more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0015] Refer to Figure 1-2As shown in the figure, the technical solution adopted in this specific embodiment is as follows: An automatically start-stop silo, including a hopper 1, on the top of the hopper 1 there is an electricity connection frame 2. The electricity connection frame 4 includes a conductive plate 21 embedded in the top of the hopper 1 and a nylon rod 22 arranged on one side of the conductive plate 21. On the nylon rod 22, a round steel column 23 can slide up and down. On the conductive plate 21, there is a first wire 25 electrically connected to the level sensor 3. At the top of the round steel column 23, there is a second wire 24 electrically connected to the level sensor 3. On the top surface of the hopper 1, there is also fixedly installed a level sensor 3. The level sensor 3 is electrically connected to the electricity connection frame 2. After the raw materials are piled up to a certain height in the hopper 1, the electricity connection frame 2 is connected, making the level sensor 3 powered on and sending a stop signal to the belt conveyor. When in use, the raw materials are sent into the hopper 1 through the belt conveyor and piled up in the hopper 1. At the same time, the level sensor 3 is powered on. At the beginning, because the piled height of the raw materials is not high, the round steel column 23 and the conductive plate 21 are not contacted simultaneously, and the nylon rod 22 insulates and isolates the conductive plate 21 from the round steel column 23, thus making the level sensor 3 open circuit and not sending out an electrical signal. When the raw materials are piled up to a certain height, at this time the raw materials contact the round steel column 23 and the conductive plate 21 simultaneously. Because the brick-making raw materials are wet and have a certain conductivity, the current will flow through the raw materials, thus connecting the contact column 23 and the conductive plate 21, making the current flow into the level sensor 3. Thereby, the level sensor 3 outputs an electrical signal, making the belt conveyor stop working. Thus, when the raw materials are full in the hopper 1, the conveying is automatically stopped, greatly improving the automation and being more convenient to use;

[0016] In the middle section of the hopper 1, there is a reinforcing rib 4, which is beneficial to improving the overall strength of the hopper 1;

[0017] On the conductive plate 21, there is also a fixing bolt 26, which is beneficial to making the installation of the conductive plate 21 more convenient and will not affect the conductive performance of the conductive plate 21;

[0018] At the bottom of the round steel column 23, there is a bullet-shaped convex block, which is beneficial to reducing the resistance of the round steel column 23 inserted into the raw materials, thus enabling the round steel column 23 to be inserted deeper and obtaining better conductive stability.

[0019] Working principle of the utility model: When the utility model is in use, raw materials are fed into hopper 1 through a belt conveyor and accumulate in hopper 1. At the same time, the level sensor 3 is powered on. At the beginning, since the stacking height of the raw materials is not high and does not simultaneously contact the round steel column 23 and the conductive plate 21, and the nylon rod 22 insulates and isolates the conductive plate 21 from the round steel column 23, thus causing the level sensor 3 to be open-circuited and not emit an electrical signal. When the raw materials are stacked to a certain height, at this time the raw materials simultaneously contact the round steel column 23 and the conductive plate 21. Since the brick-making raw materials are wet and have a certain electrical conductivity, the current will flow through the raw materials, thereby connecting the contact column 23 and the conductive plate 21 and causing the current to flow into the level sensor 3. As a result, the level sensor 3 outputs an electrical signal to make the belt conveyor stop working. Thus, when the raw materials are fully stacked in hopper 1, the conveying automatically stops, greatly improving the automation and making it more convenient to use.
