Description

Technical Field

[0001] This utility model relates to the field of water-stabilized mixing plant technology, and in particular to a cold material hopper for a water-stabilized mixing plant. Background Technology

[0002] The cold aggregate hopper of the water-stabilized mixing plant is a key component of the water-stabilized mixing equipment. It is mainly used to store and measure various cold aggregates (such as stone powder, crushed stone, sand and gravel) to provide accurate raw material proportions for subsequent water-stabilized material mixing.

[0003] Cold aggregate hoppers typically consist of multiple independent bins, each corresponding to a specific type of aggregate. Each bin is equipped with a feeding device at the bottom to quantitatively deliver the aggregate to the subsequent metering system. The top of the bin is usually fitted with a dust cover to reduce dust pollution.

[0004] To reduce material buildup, a vibrating discharge mechanism is typically installed on cold hoppers. Currently, this mechanism usually uses a vibrating motor welded to one side of the hopper body via a connecting steel plate. The vibrating motor generates excitation force to allow the aggregate accumulated on the side plate to fall smoothly. However, this structure requires the entire cold hopper to vibrate, limiting vibration. Ensuring vibration across the entire hopper requires a high-power motor, which can easily damage the hopper's connecting parts, resulting in poor performance. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cold material hopper for a water-stabilized mixing plant.

A cover plate is provided on the top of the vibrating plate. A vibrator corresponding to the vibrating plate is provided on the outer side of the cold material hopper.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Reference Figure 1-6 A cold hopper for a water-stabilized mixing plant includes a cold hopper 1 and a support 3 for supporting the cold hopper 1. A vibrating plate 2 is provided on the inner side of the cold hopper 1. The vibrating plate 2 is controlled to vibrate at a certain frequency and amplitude to ensure the continuity of stone powder feeding during the water-stabilized production process and to ensure the quality of the water-stabilized mixture. The top of the vibrating plate 2 is hinged to the inner wall of the cold hopper 1. By swinging, stone powder is prevented from caking and remaining on the inner wall of the cold hopper 1. A cover plate 8 is provided on the top of the vibrating plate 2 to reduce the flow of stone powder into the gaps of the vibrating plate 2. A vibrator 6 corresponding to the vibrating plate 2 is provided on the outer side of the cold hopper 1 to provide a source of vibration power.

[0025] As needed, two types of vibrating plates 2 can be set to achieve multiple vibration modes, which are divided into a first vibrating plate 21 and a second vibrating plate 22. The vibrator 6 is set in correspondence with the first vibrating plate 21 and the second vibrating plate 22, including a first vibrator 61 and a second vibrator 62. The first vibrator 61 and the second vibrator 62 are equipped with a variable frequency motor. The variable frequency motor is connected to a frequency modulation power supply to adjust the speed and change the vibration frequency.

[0026] Option 1, such as Figure 5 As shown, the first vibrator 61 and the first vibrating plate 21 are fixedly connected by a connecting block 611. The side wall of the cold hopper 1 is provided with a clearance hole that matches the connecting block 611. A sealing plate 612 is provided between the connecting block 611 and the inner wall of the cold hopper 1. When the first vibrator 61 vibrates, it generates kinetic energy, which drives the connecting block 611 to swing significantly through the connecting block 611, thereby promoting the flow of stone powder, improving the stability of stone powder conveying, and avoiding blockage.

[0027] Option 2, such as Figure 6As shown, the side wall of the cold hopper 1 has an installation hole, and an elastic plate 621 is embedded in the installation hole. The second vibrator 62 is fixedly connected to the elastic plate 621. A vibrating block 622 is fixedly installed on one side of the second vibrator 62. The vibrating block 622 abuts against the second vibrating plate 22. The second vibrator 62 is restricted by the elastic plate 621 and is suitable for small-amplitude high-frequency vibration. The vibration is transmitted to the second vibrating plate 22 through the vibrating block 622 to loosen the stone powder.

[0028] Option 1 and Option 2 can be selected or configured simultaneously as needed. The first vibrating plate 21 and the second vibrating plate 22 are respectively set on both sides of the inside of the cold hopper 1 to improve the reliability of vibrating loose stone powder.

[0029] A conveyor belt 4 is provided on the lower side of the cold hopper 1. The outlet of the cold hopper 1 is located at one end of the conveyor belt 4. The outlet of the cold hopper 1 and the upper surface of the conveyor belt 4 are close to each other. Corrugated baffles 41 are provided on both sides of the conveyor belt 4 to prevent stone powder from scattering and leaking out. A lifting frame 5 is provided on the lower side of the conveyor belt 4 to adjust the distance between the outlet of the cold hopper 1 and the upper surface of the conveyor belt 4, adjust the discharge efficiency, and facilitate the cleaning of accumulated stone powder. A drive device 7 is provided on the conveyor belt 4. The drive device 7 includes a motor and a drive wheel to control the operation of the conveyor belt 4 and adjust the discharge speed. A control valve 11 corresponding to the conveyor belt 4 is provided on one side of the lower part of the cold hopper 1. A valve port is opened on the side of the outlet of the cold hopper 1 in the discharge direction of the conveyor belt 4. A valve seat corresponding to the control valve 11 is provided on the valve port. An adjusting screw is provided on the control valve 11. The opening degree of the control valve 11 is changed by adjusting the adjusting screw to adjust the discharge amount.

[0030] The cover plate 8, sealing sheet 612 and elastic plate 621 are made of rubber. The sealing sheet 612 and elastic plate 621 are made of multi-layer fabric-reinforced rubber sheets, which improves durability and extends service life.

[0031] In this embodiment, stone powder falls into the cold hopper 1 through the storage bin, and falls onto the conveyor belt 4 through the lower discharge port. The discharge amount is adjusted by the control valve 11.

[0032] During this period, vibrator 6 is turned on. Depending on the blockage, the first vibrator 61 or the second vibrator 62 is turned on. The first vibrating plate 21 is controlled to swing at a large amplitude, and the second vibrating plate 22 vibrates at a small amplitude and high frequency to loosen the stone powder and improve the reliability and stability of the discharge. If severe blockage occurs, the first vibrator 61 and the second vibrator 62 are turned on at the same time to vibrate and loosen the stone powder from both sides. At the same time, the lifting frame 5 controls the conveyor belt 4 to move away from the discharge port of the cold hopper 1 to improve the discharge efficiency and clear the blockage.
