Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sand and gravel aggregate diversion equipment, specifically to a machine-made sand material flow regulating hopper. Background Technology
[0002] To meet the demands of the water conservancy and hydropower industry for roller-compacted concrete and conventional concrete, the aggregate production line should possess both dry and wet sand production capabilities. Dry sand production produces dry sand with a high powder content, while wet sand production produces wet sand with a low powder content. The dry and wet sand produced on the aggregate production line need to be output separately, one through a dry process output channel and the other through a wet process output channel. The wet process output channel is closed when dry sand production is required, and vice versa. When both dry and wet sand need to be produced simultaneously, both output channels are opened simultaneously, and the production ratio of dry and wet sand can be adjusted by opening and closing gates.
[0003] However, both the existing dry and wet output channels suffer from severe wear from the sand, resulting in significant losses and increased production costs.
[0004] In summary, it is necessary to develop a material flow regulating hopper for manufactured sand to solve the problem that both existing dry and wet output channels are severely worn by sand. Utility Model Content

[0024] The discharge port of the hopper 1 is connected to the inlet of the main channel 2 and the inlet of the bypass channel 5, respectively. A main channel opening / closing adjustment mechanism 3 is installed on the discharge port of the main channel 2 to adjust the opening and closing of the discharge port and its degree. A bypass opening / closing adjustment mechanism 6 is installed on the discharge port of the bypass channel 5 to adjust the opening and closing of the discharge port and its degree. Multiple main channel baffles 4 are sequentially spaced on the bottom plate along which the material (specifically, manufactured sand) flows within the main channel 2 to block some of the material at the bottom of the main channel 2, forming a lining and reducing wear and impact on the bottom plate. Multiple bypass baffles 7 are sequentially spaced on the bottom plate along which the material (specifically, manufactured sand) flows within the bypass channel 5, blocking some of the material at the bottom of the bypass channel 5, forming a lining and reducing wear and impact on the bottom plate.
[0025] The distance between any two adjacent main road baffles 4 is 300mm, which helps to effectively reduce the wear of materials on the bottom wall of the main road channel 2.
[0026] The distance between any two adjacent bypass baffles 7 is 300mm, which helps to effectively reduce the wear of materials on the bottom wall of the bypass channel 5.
[0027] The main channel opening and closing adjustment mechanism 3 includes a first driving component 3.1 (specifically, a driving cylinder), a first sliding door 3.2, and a first slide rail 3.3. The first slide rail 3.3 is provided on the discharge port of the main channel 2. The first sliding door 3.2 is slidably mounted on the first slide rail 3.3 and connected to the telescopic working end of the first driving component 3.1. The fixed end of the first driving component 3.1 is located on the main channel 2. The size of the first sliding door 3.2 is greater than or equal to the size of the discharge port of the main channel 2. The first driving component 3.1, in conjunction with the first sliding door 3.2, slides along the first slide rail 3.3 to adjust the opening and closing of the first sliding door 3.2 at the discharge port of the main channel 2 and the degree of opening.
[0028] The bypass opening and closing adjustment mechanism 6 includes a second driving component 6.1 (specifically, a driving cylinder can be selected), a second sliding door 6.2, and a second slide rail 6.3. The second slide rail 6.3 is provided on the discharge port of the bypass channel 5. The second sliding door 6.2 is slidably mounted on the second slide rail 6.3 and connected to the telescopic working end of the second driving component 6.1. The fixed end of the second driving component 6.1 is provided on the bypass channel 5. The size of the second sliding door 6.2 is greater than or equal to the size of the discharge port of the bypass channel 5. The second driving component 6.1, in conjunction with the second sliding door 6.2, slides along the second slide rail 6.3 to adjust the opening and closing of the second sliding door 6.2 at the discharge port of the bypass channel 5 and the degree of opening.
[0029] The manufactured sand flow regulating hopper also includes a support frame 8 (specifically, a steel support frame can be selected); the support frame 8 is located below the hopper 1 and connected to the bottom of the hopper 1, and is used to support the hopper 1 to be fixedly installed below the manufactured sand that needs to be diverted.
[0030] The operating principle of the manufactured sand flow regulating hopper is as follows:
[0031] Inject the manufactured sand that needs to be diverted into the hopper 1;
[0032] When dry sand needs to be produced, the first driving component 3.1 is linked to the first sliding door 3.2 to slide along the first slide rail 3.3, which is used to adjust the first sliding door 3.2 to open the discharge port of the main channel 2 and realize the output of sand, which is dry sand; during the dry sand output process, the second driving component 6.1 is linked to the second sliding door 6.2 to slide along the second slide rail 6.3, which is used to adjust the second sliding door 6.2 to close the discharge port of the bypass channel 5;
[0033] When wet sand needs to be produced, the second drive component 6.1 is linked to the second sliding door 6.2 to slide along the second slide rail 6.3, which is used to adjust the second sliding door 6.2 to open the discharge port of the bypass channel 5, realize the output of sand, and obtain wet sand after being washed by the integrated sand washing machine; during the output of wet sand, the first drive component 3.1 is linked to the first sliding door 3.2 to slide along the first slide rail 3.3, which is used to adjust the first sliding door 3.2 to close the discharge port of the main channel 2;
[0034] When wet sand and dry sand need to be produced in proportion, the first driving component 3.1 is linked to the first sliding door 3.2 to slide along the first slide rail 3.3, which is used to adjust the opening of the discharge port of the first sliding door 3.2 to the main channel 2; the second driving component 6.1 is linked to the second sliding door 6.2 to slide along the second slide rail 6.3, which is used to adjust the opening of the discharge port of the second sliding door 6.2 to the bypass channel 5; wherein, the opening size of the discharge port of the bypass channel 5 and the opening size of the discharge port of the main channel 2 are determined by the ratio of wet sand and dry sand produced;
[0035] Most importantly, in order to solve the problem that both the existing dry and wet output channels are severely worn by sand, this embodiment uses a main road baffle 4 to block part of the material near the bottom wall of the main road channel 2, thereby reducing the wear and impact of the material on the bottom wall of the main road channel 2; and uses a bypass baffle 7 to block part of the material near the wall of the bypass channel 5, thereby reducing the wear and impact of the material on the bottom wall of the bypass channel 5.
[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
