[0002] The homogenization silo is one of the most important components of the raw material system of modern float glass production line. It is necessary to ensure that the homogenization silo can supply qualified silica sand raw materials at any time to meet the process requirements of subsequent glass production batching. The sand rake is one of the most important equipment in the homogenization silo. Its performance and working state have a great impact on glass production and product quality. The working principle of the sand rake is to drive the sand rake chain to rotate through the driving device. The chain is equipped with rake teeth to rake the sand; the raked silica sand flows to the bottom belt conveyor and is transported out of the homogenization silo. The photovoltaic glass raw material homogenization silo generally uses a rake-type sand scraper to homogenize the silica sand. The operation of the equipment is controlled by the operator in the sand scraper control room to realize the functions of the rake-type sand scraper such as reciprocating motion, deep rake, shallow rake or fixed-point rake. Due to the unsaturated workload of this position and the dust and noise on site when the equipment is running. Not only is the working environment harsh, but there is also a certain risk for on-site personnel. Especially when the scale of the homogenization silo is relatively large.

[0027] Embodiment 1:

[0028] As Figure 1 shown, this embodiment describes a rake sand machine device for a photovoltaic glass homogenization bin. The device is arranged in the homogenization bin 18 for photovoltaic glass production. On the long side ground of the rectangular homogenization bin 18, a large garage guide rail 15 is arranged. A receiving belt 16 for transporting raw materials is arranged in parallel on the side of the large garage guide rail 15. A rack 20 and a rake arm 19 are arranged in a direction perpendicular to the large garage guide rail 15, and a rake chain 17 is arranged on the rake arm 19. The structures and positional relationships of the large garage guide rail 15, the receiving belt 16, the rake chain 17, the rake arm 19, and the rack 20 are the same as those in the prior art. The driving devices and movement modes of the rake chain 17 and the rake arm 19 are also the same as those in the prior art, and the driving devices are not shown in the figure.

[0029] On one side of the rack 20, there are provided a left upper limit switch 1 for the rake arm 19 in the large garage, a right upper limit switch 2 for the large garage, a left lower limit switch 9 for the large garage, and a right lower limit switch 10 for the large garage. Among them, the left upper limit switch 1 for the large garage and the left lower limit switch 9 for the large garage form a group, which is used to detect the in-place situation on the left side; the right upper limit switch 2 for the large garage and the right lower limit switch 10 for the large garage form a group, which is used to detect the in-place situation on the right side.

[0030] On the rake arm 19, there are also provided left and right rope collision switches 3, a chain break detection sensor 4, a chain speed detection sensor 5, an upper limit sensor 6 for the rake arm, a lower limit sensor 7 for the rake arm, and a loose rope detection sensor 8. The left and right rope collision switches 3 are divided into left and right parts, which are respectively used to detect obstacles or piled materials on the two sides; the chain break detection sensor 4 is used to detect whether the rake chain 17 is broken; the chain speed detection sensor 5 is used to detect the movement speed of the rake chain 17; the upper limit sensor 6 for the rake arm detects the upper end position of the rake arm 19, so as to perform upper limit on the rake arm 19. The lower limit sensor 7 for the rake arm detects the lower end position of the rake arm 19, so as to perform lower limit on the rake arm 19. The loose rope detection sensor 8 is used to detect the loose rope situation.

[0031] At the middle position of the rake arm 19, there is also provided a rake arm video sensor 11 for monitoring the working state of the rake arm 19 and related components.

[0032] At the high position on the left side of the homogenizing silo 18, there is provided a head video sensor 12 for the silo. On the rack 20, there is provided a large garage video sensor 13. At the high position on the right side of the homogenizing silo 18, there is provided a tail video sensor 14 for the silo. The head video sensor 12 for the silo, the large garage video sensor 13, and the tail video sensor 14 for the silo monitor the working state of the whole device from different positions and provide video feedback.

[0033] During operation, the working actions of the whole rake sanding machine device are basically the same as those of the prior art. The following part describes the working conditions of the sensors:

[0034] The left upper limit switch 1 for the large garage and the right upper limit switch 2 for the large garage are arranged above the left side of the large garage guide rail 15, and the left lower limit switch 9 for the large garage and the right lower limit switch 10 for the large garage are arranged below the left side of the large garage guide rail 15. If the left upper limit switch 1 for the large garage and the left lower limit switch 9 for the large garage are triggered simultaneously, or the right upper limit switch 2 for the large garage and the right lower limit switch 10 for the large garage are triggered simultaneously, there will be no alarm and the control system will send a power-on signal, and the right or left position of the silo will be powered on. If they are not triggered simultaneously, the control system will send a large vehicle right limit fault signal or a large vehicle left limit fault signal, resulting in shutdown.

[0035] The chain break detection sensor 4 is for chain break detection. If the chain break detection sensor 4 fails to detect the chain movement signal, the control system will output a chain break signal. An alarm will occur and the machine will stop. It is necessary to check whether the chain is broken or whether the proximity switch detection is normal.

[0036] Another proximity switch is the chain speed detection sensor 5, which is used to judge the chain speed situation.

[0037] When the upper limit sensor 6 of the rake arm is triggered, it means that the rake arm 19 has reached the upper limit and the rake arm 19 cannot rise. When the lower limit sensor 7 of the rake arm is triggered, it means that the rake arm 19 has reached the lower limit and cannot continue to descend.

[0038] When the right pull rope switch of the left and right rope collision switches 3 is triggered, it means that there is an obstacle or a material pile on the right side of the rake arm. When the left pull rope switch of the left and right rope collision switches 3 is triggered, it means that there is an obstacle or a material pile on the left side of the rake arm.

[0039] Brief description of the control mode:

[0040] Turn on the power control power button, and the power is energized. Turn on the operation of the rake chain 17, and then lower the rake chain 17 to the given depth. The feeding depth is divided into three gears (shallow, medium, deep). It can be set on the console or in the remote control room, and the feeding time can be controlled by the built-in timer of the control system.

[0041] Start the slow operation of the large vehicle of the raking machine. The operation of the large vehicle is frequency-controlled. Select the running direction and speed of the large vehicle on the console or in the remote control room. The control system controls the large vehicle to move right or left, and controls the high-speed operation or the production-speed operation. If a material pile is encountered midway, trigger the left and right rope collision switches 3 on both sides of the rake chain 17, and the large vehicle will stop. The operator needs to change the running direction of the large vehicle.

[0042] Manual operation: Manually select each gear parameter (feeding depth, slow speed) to determine the running direction of the large vehicle. The large vehicle needs to be manually stopped when it reaches the edge of the area.

[0043] Semi-automatic operation: Select the feeding depth, set the distance of the operation area, and start the direction. This machine will enter semi-automatic operation. It is necessary to manually switch the direction when reaching the edge of the area.

[0044] Fully automatic operation: After determining the feeding depth and running direction, this machine will automatically rake the material layer by layer in a reciprocating manner. Note: Automatic reciprocation requires triggering the upper left limit switch 1 and the lower left limit switch 9 of the large vehicle garage, or the upper right limit switch 2 and the lower right limit switch 10 of the large vehicle garage.

[0045] In addition, it should be noted that for the specific embodiments described in this specification, the shapes, names, etc. of the components can be different. Any equivalent or simple changes made according to the structure, features, and principles described in the utility model patent concept are included in the protection scope of the utility model patent. Those skilled in the technical field to which the utility model belongs can make various modifications, supplements, or use similar methods for substitution to the specific embodiments described, as long as they do not deviate from the structure of the utility model or exceed the scope defined by this claim book, they should all fall within the protection scope of the utility model.
