Description

Technical Field

[0001] This utility model relates to the field of brick-making technology, specifically to a fast material discharge hopper for a brick-making machine. Background Technology

[0002] A brick-making machine is a mechanical device used to press raw materials (such as soil, clay, cement, sand, cinder, slag, etc.) into bricks of fixed shapes and sizes through pressure and vibration. It includes a main frame, hydraulic system, vibration system, mold, and control system. Some machines are also equipped with a plate feeder and a brick output system. The main frame provides support for the entire brick-making machine and provides power through the hydraulic system. After the material is put into the mold, it is placed on the vibration system to make the material more compact. Then, pressure is applied to press the material firmly into the mold, and after drying, bricks are formed. Various building bricks can be produced efficiently and with high quality through mechanization.

[0003] The feeding hopper is an important component of the brick making machine. It can hold materials and uses a hydraulic cylinder to control the opening and closing of the gate at the bottom of the feeding hopper to output the materials to the feeding trolley for material distribution.

[0004] Although the aforementioned existing technologies can solve the corresponding technical problems, they still have certain drawbacks: the existing discharge hopper controls the opening and closing of the opening and closing gate below the discharge hopper by extending or retracting the hydraulic cylinder. However, when the hydraulic cylinder is running, its stroke distance is affected by the input liquid. The pressure generated by the liquid is different when the temperature is high or low. Therefore, the opening and closing accuracy of the existing discharge hopper is easily affected by external factors and has poor stability. At the same time, the hydraulic cylinder can only push a single opening and closing gate to open and close, resulting in a small opening range below the discharge hopper and a slow discharge speed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a fast material discharge hopper for brick making machines that offers high stability and fast material discharge speed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rapid feeding hopper for a brick making machine, comprising a hopper body, an opening and closing door structure at the bottom of the hopper body, a transmission box fixedly mounted on one side of the hopper body, a power motor mounted on the transmission box, and a pull rod mounted on one side of the transmission box, the bottom end of which is movably engaged with one side of the opening and closing door structure.

[0007] A further improvement is that a fixing block is provided at the top edge of the hopper body.

[0008] A further improvement is that an inspection door is detachably provided on one side of the hopper body.

[0009] A further improvement is that the opening and closing door structure includes a first opening and closing door that is movably engaged with the bottom of the hopper body, and one side of the first opening and closing door is movably engaged with the bottom end of the pull rod.

[0010] A further improvement is that a second opening and closing door is movably engaged at the bottom of the hopper body, and the second opening and closing door can fit against the first opening and closing door to seal the bottom of the hopper body.

[0011] A further improvement is that a first gear is installed on the top of the first opening door, and a second gear is installed on the top of the second opening door, with the first gear and the second gear meshing with each other.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When this utility model is used, the material is placed in the hopper body, and the power motor drives the transmission box to output power, so that the pull rod pulls the opening and closing door structure, thereby allowing the material to be sent out of the hopper body. Compared with the hydraulic cylinder drive, the power output by the power motor is more stable and is not affected by the ambient temperature, thereby improving the opening and closing accuracy of the opening and closing door structure and making it more stable in use. At the same time, the opening and closing door structure has a first opening and closing door and a second opening and closing door. The first gear and the second gear at the top of the two doors mesh with each other. After the first opening and closing door is opened, the first gear at its top will drive the second gear to rotate synchronously, thereby causing the second opening and closing door to open synchronously as well. This greatly increases the opening at the bottom of the hopper body, allowing the material to be sent out more quickly and effectively improving the discharge speed. Attached Figure Description

Detailed Implementation

[0015] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0016] See Figure 1-3As shown, the technical solution adopted in this specific embodiment is: a rapid feeding hopper for a brick making machine, including a hopper body 1, with an opening and closing door structure at the bottom of the hopper body 1, a transmission box 3 fixedly installed on one side of the hopper body 1, a power motor 2 installed on the transmission box 3, and a pull rod 4 installed on one side of the transmission box 3, the bottom end of which is movably engaged with one side of the opening and closing door structure. The opening and closing door structure includes a first opening and closing door 5 movably engaged with the bottom of the hopper body 1, one side of the first opening and closing door 5 being movably engaged with the bottom end of the pull rod 4. In use, material is placed into the hopper body 1, and the power motor 2 controls the transmission box 3 to output power, thereby closing the first opening and closing door 5 and sealing the bottom of the hopper body 1. The transmission box 3 has a gear set inside, the main purpose of which is to change the power output direction of the power motor 2 through the gear set. This technology is widely used in the machinery industry and is existing technology, so it will not be discussed further here. In detail, when material needs to be discharged, the power motor 2 is started, and the power motor outputs power to the transmission box 3. After the transmission box 3 changes the direction of power, the pull rod 4 is lifted upward, which in turn drives one side of the first opening and closing door 5 to be lifted, thereby causing the first opening and closing door to flip up along the position where it is movably engaged with the hopper body 1, thus no longer closing the hopper body 1. This allows the material to be discharged outward along the bottom of the hopper body 1. Compared with the hydraulic cylinder drive, the power output driven by the power motor 2 is more stable and is not affected by the ambient temperature. It can output power stably under various ambient temperatures, which makes the movement distance of the pull rod more stable, so that the movement distance is not too large or too small. This makes the opening and closing angle of the first opening and closing door 5 more stable, so that the opening and closing angle is not too large or too small, thereby improving the opening and closing accuracy of the first opening and closing door 5 and making it more stable in use. The top edge of the hopper body 1 is also provided with a fixing block 9, which makes it easier to install the hopper body 1 onto the main frame; An inspection door 10 is detachably provided on one side of the hopper body 1, which is beneficial for quickly checking whether there is material accumulation or damage inside the hopper body 1 by removing the inspection door 10 during maintenance. The bottom of the hopper body 1 is also equipped with a second opening and closing door 6. The second opening and closing door 6 can fit and close the bottom of the hopper body 1 with the first opening and closing door 5. This allows the second opening and closing door 6 to be opened manually at the same time when discharging material. This allows the second opening and closing door 6 to work with the first opening and closing door 5 to form a larger discharge port, which greatly increases the opening at the bottom of the hopper body 1, allowing the material to be sent out more quickly and effectively improving the discharge speed. The first opening and closing door 5 is equipped with a first gear 7 on its top, and the second opening and closing door 6 is equipped with a second gear 8 on its top. The first gear 7 and the second gear 8 mesh with each other. When the first opening and closing door 5 is opened, the first gear 7 on its top will drive the second gear 8 to rotate synchronously, thereby causing the second opening and closing door 6 to open synchronously as well. This eliminates the need for manual opening of the second opening and closing door 6. When discharging material, the opening at the bottom of the hopper body 1 is greatly enlarged, allowing the material to be sent out more quickly and effectively improving the discharge speed.

[0017] The working principle of this utility model is as follows: When using this utility model, material is placed into the hopper body 1, and the power motor 2 controls the transmission box 3 to output power, thereby closing the first opening and closing door 5, sealing the bottom of the hopper body 1. The transmission box 3 contains a gear set, the main purpose of which is to change the power output direction of the power motor 2 through the gear set. This technology is widely used in the machinery industry and is existing technology, so it will not be described in detail here. When it is necessary to discharge material, the power motor 2 is started, so that the power motor outputs power to the transmission box 3. After the transmission box 3 changes the power direction, the pull rod 4 is lifted upward, thereby synchronously driving the first opening and closing door 5. One side of the opening and closing door 5 is lifted, causing the first opening and closing door to flip up along the position where it is movably engaged with the hopper body 1, thus no longer closing the hopper body 1. This allows the material to be discharged outward along the bottom of the hopper body 1. Compared to hydraulic cylinder drive, the power output driven by the power motor 2 is more stable and unaffected by ambient temperature. It can output power stably under various ambient temperatures, which makes the movement distance of the pull rod more stable, preventing it from being too large or too small. This, in turn, makes the opening and closing angle of the first opening and closing door 5 more stable, preventing it from being too large or too small, thereby improving the opening and closing accuracy of the first opening and closing door 5 and making it more stable in use.
