[0028] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-8 This utility model provides a technical solution: a coal mixing device, including a mixing box 1, a support 11 disposed at the lower end of the mixing box 1, and a mixing mechanism 2 disposed in the mixing box 1 for mixing coal, and further including:
[0030] The sealing cover 3 is adjustablely positioned at the upper end of the mixing box 1 to seal the upper end of the mixing box 1.
[0031] The opening mechanism 4 is located on both sides of the mixing box 1 and connected to the sealing cover 3, and is used to control the opening and closing of the sealing cover 3;
[0032] The lid opening mechanism 4 includes:
[0033] The power unit is installed on the mixing box 1;
[0034] The connector is mounted on the power component and connected to the sealing cover 3.
[0035] It should be noted that during operation, when mixing coal, the opening mechanism 4 opens the sealing cover 3, and then the coal to be mixed is added into the mixing box 1. Moisture is evenly added into the mixing box 1, and then the opening mechanism 4 is driven to close the sealing cover 3 on the top of the mixing box 1, sealing the top of the mixing box 1. Then, the mixing mechanism 2 is opened to mix the coal powder inside the mixing box 1. By adding the sealing cover 3 and the opening mechanism 4, the automatic opening and closing of the sealing cover 3 is achieved, reducing the labor intensity of operators, improving work efficiency, and ensuring safe and reliable operation. It not only facilitates the addition of coal into the mixing box 1, but also effectively solves the problem of poor sealing in traditional coal mixing equipment. The sealing cover 3 is adjustable and set at the top of the mixing box 1, which can tightly seal the mixing box 1 to prevent coal dust leakage, thereby improving the working environment and protecting the health of operators.
[0036] In one embodiment, the power component includes a fixed rod 42 fixed on the mixing tank 1, a mounting bracket 41 fixed on the fixed rod 42, and a second power component 43 disposed on the mounting bracket 41. A connecting member is disposed at the power output end of the second power component 43. The second power component 43 includes, but is not limited to, a hydraulic cylinder, a linear guide, an electric push rod, and a pneumatic cylinder.
[0037] This design is for reference. Figure 1-7 The fixing rod 42 is firmly fixed to the mixing box 1, providing a stable support base for the entire opening mechanism 4. The mounting bracket 41 is fixed to the fixing rod 42, ensuring the installation position and operational stability of the second power component 43. Driven by the second power component 43, the connecting piece can drive the sealing cover 3 to achieve automatic opening and closing, greatly simplifying the operation process. Operators do not need to manually operate the sealing cover 3, reducing labor intensity, improving work efficiency, and avoiding potential safety hazards caused by manual operation.
[0038] In one embodiment, the connector includes a mounting shaft 410 disposed on the mixing tank 1, a drive gear 45 sleeved on a mounting shaft 410, a swing plate 46 fixed on the drive gear 45, and a mounting plate 49 disposed on the upper end of the swing plate 46. A sealing cover 3 is fixed on the mounting plate 49, and a rotating plate 44 connected to the second power member 43 is disposed at the lower end of the drive gear 45.
[0039] This design is for reference. Figure 4-7 The second power component 43 drives the rotating plate 44 to rotate, which in turn drives the drive gear 45 to rotate. The drive gear 45 drives the swing plate 46 to be reversed along the mounting shaft 410, so that the sealing cover 3 is rotated out from the top of the mixing box 1. Then the top of the mixing box 1 is opened for feeding.
[0040] In one embodiment, a driven gear 47 is sleeved on a mounting shaft 410. The driven gear 47 is meshed with the driving gear 45. A push plate 48 is provided on the side of the driven gear 47 away from the rotating plate 44. A sealing cover 3 is fixed to the upper end of the push plate 48.
[0041] This design is for reference. Figure 6 ,as well as Figure 7 The meshing connection between the drive gear 45 and the driven gear 47 ensures that they can rotate synchronously. When the second power component 43 drives the rotating plate 44 to rotate the drive gear 45, the driven gear 47 will also rotate, thereby driving the push plate 48 and the sealing cover 3 to move. This synchronous motion mechanism ensures that the two sealing covers 3 can open and close at the same time, improving the consistency and efficiency of the equipment operation. The sealing covers 3 are symmetrically arranged. When the sealing covers 3 are opened, they are stored on both sides of the mixing box 1, which makes it convenient for the staff to add the coal materials to be mixed into the interior of the mixing box 1.
[0042] In one embodiment, a feeding box 12 is provided at the lower end of the mixing box 1. A cover 13 is adjustablely provided inside the feeding box 12. A first power member 14 is provided at the lower end of the mixing box 1. The first power member 14 is connected to the cover 13. A moving groove 1201 for moving the cover 13 is provided on the feeding box 12. A fixing groove 1202 for placing the cover 13 is provided on the inner side of the feeding box 12. The first power member 14 includes, but is not limited to, a hydraulic cylinder, a linear guide rail, an electric push rod, and a pneumatic cylinder.
[0043] This design is for reference. Figure 5 ,as well as Figure 8 After the coal is mixed, the first power component 14 is activated to drive the baffle 13 to move within the moving trough 1201, thereby pulling the baffle 13 out of the feeding box 12, allowing the mixed coal inside the mixing box 1 to be discharged. The gap between the baffle 13 and the outlet of the feeding box 12 can be adjusted to control the falling speed and amount of coal. The introduction of the first power component 14 realizes the automated control of the baffle 13, eliminating the need for manual adjustment and greatly improving the convenience of operation and work efficiency.
[0044] In one embodiment, the mixing mechanism 2 includes a motor 21 fixed to the upper end of the bracket 11, a rotating shaft 22 fixed to the power output end of the motor 21, a reduction gear 23 disposed on the rotating shaft 22, a mixing shaft 24 disposed on the reduction gear 23, a pulverizing blade 26 disposed on the mixing shaft 24, and a spiral blade 25 disposed on the mixing shaft 24. The pulverizing blade 26 and the spiral blade 25 are both disposed inside the mixing box 1.
[0045] This design is for reference. Figure 5The motor 21 provides power, which is transmitted to the mixing shaft 24 through the rotating shaft 22 and the reduction gear 23, so that the crushing blade 26 and the spiral blade 25 rotate simultaneously. The crushing blade 26 can quickly crush the coal into smaller particles, while the spiral blade 25 can fully mix the crushed coal particles, achieving efficient and uniform mixing and crushing effect. After the coal is mixed, the motor 21 drives the spiral blade 25 to convey the coal to one side of the feed box 12, so that the coal is discharged from the feed box 12.
[0046] Furthermore, if the embodiments involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relation to the specification. The significance or implied number of the indicated technical features is not specified. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
