Description

Technical field:

[0001] The utility model belongs to the technical field of construction engineering equipment, and in particular relates to a material unloading and falling position regulating device. Background technology:

[0002] The belt conveyor system is the main equipment of bulk cargo terminals. Usually, the commonly used equipment in bulk cargo terminals, such as chain bucket ship unloaders, screw ship unloaders, ship loaders, bucket wheel stackers and reclaimers, need to be used in conjunction with the belt conveyor system. However, in the belt conveyor system, the belt may deviate due to various reasons, such as the material drop point is not on the center line, the roller rubber wears unevenly, the axis of the drive roller and the redirecting roller are inconsistent, and the tension on both sides of the belt is different.

[0003] As for the continuous ship unloading (loading) equipment such as the chain bucket unloader, screw unloader, loader, bucket wheel stacker and reclaimer mentioned above, on the one hand, the cargoes loaded and unloaded at the wharf are diverse, including coal, grain, mineral powder, etc. The specific gravity of each material varies greatly, so the drop points of different materials are different. Therefore, the drop points need to be adjusted in time whenever the materials are changed. On the other hand, the cantilever system needs to rotate at multiple angles during operation. When the drop tail car and the lower receiving belt rotate, that is, the drop tail car and the lower receiving belt are not in a straight line, but at a certain angle, the angle of the conventional bucket wheel machine can reach ±110 degrees. Since the material flies out of the discharge belt at a certain speed, when the discharge belt and the receiving belt are in a straight line, the material falls on the receiving belt. Due to the speed and inertia of the material, the material will give the receiving belt a force along the direction of the material throwing. If the receiving belt and the discharge belt are in a straight line at this time, this inertial force will not cause the receiving belt to deviate. However, when the receiving belt and the discharging belt are at a certain angle, the direction of the material being thrown will be at a certain angle to the receiving belt, and the inertial force of the material being thrown will give the receiving belt a lateral displacement force, which will cause the receiving belt to deviate, and in severe cases even affect production. Therefore, as the angle changes, the material drop point also needs to be adjusted in a timely manner.

[0004] Currently, there are two conventional ways to adjust the drop point. The first one is to weld a two-stage or three-stage baffle seat on the upper part of the hopper, and the baffle can be switched among three stages; a manual adjustment rod is installed at the bottom of the baffle, and the angle of the baffle can be adjusted by the adjustment rod; the second one is to weld a two-stage or three-stage baffle seat on the upper part of the hopper, and the baffle can be switched among three stages; a manual push rod adjustment rod is installed at the bottom of the baffle, and the angle of the baffle can be adjusted by the manual push rod adjustment rod.

[0005] Although the two methods can achieve the adjustment of the material falling to different degrees, there are generally the following problems: 1. The baffle is too heavy to be adjusted by one person, and multiple people must cooperate, especially when adjusting the third position of the adjusting baffle on the upper baffle seat, it is very difficult; 2. Because the upper baffle seat of the adjusting baffle is inside the funnel, if the position of the adjusting baffle on the upper baffle seat is adjusted, the equipment must be stopped to adjust, resulting in a long interruption of the production operation of the process equipment; 3. When adjusting the angle of the adjusting baffle, the above two methods are manual adjustments, which are difficult to adjust, and the equipment must be stopped to reduce the impact of the material on the adjusting baffle and reduce human labor. 4. Since the baffle needs to be adjusted frequently according to different angles and materials, the above two methods are difficult to adjust. Maintenance personnel need to adjust it many times to the required position and angle, which is labor-intensive and time-consuming, resulting in a lot of downtime costs, and even unable to find a suitable position; 5. The above two methods can only realize the front and back three-level movement of the adjustment baffle, as well as the front and back angle adjustment. From a functional point of view, it only realizes single-dimensional adjustment and cannot cover all working conditions; 6. There are no baffles on both sides of the adjustment baffle, and the material is easy to slide from both sides of the adjustment baffle and cannot fall to the center of the belt below.

[0006] Based on this, the utility model proposes a novel, multi-dimensional unloading and dropping position adjustment device to solve the above problems. Summary of the invention:

[0059] Example 6

[0060] This embodiment provides a method for adjusting the position of unloading and dropping of materials, which is implemented based on the adjustment device described in Embodiment 5, specifically:

[0061] By controlling the two first push rods 2-1 to extend / retract synchronously, the baffle device can be driven to move toward / away from the material, thereby adjusting the relative position of the baffle 1 in the hopper, such as Figure 7 When one first push rod 2-1 extends forward and the other first push rod 2-1 does not move, or one first push rod 2-1 extends forward and the other first push rod 2-1 retracts, or one first push rod 2-1 retracts and the other first push rod 2-1 does not move, the inclination angle of the baffle 1 can be adjusted, as shown in FIG. Figure 8By controlling the second push rod 2-2 to extend or retract, the rotation angle of the baffle 1 can be adjusted, as shown in FIG. Fig. 9 shown.

[0062] When the unloading material changes from a material with a low specific gravity to a material with a high specific gravity, such as coal (with a specific gravity of about 0.85t / m 3 ) into mineral powder (specific gravity about 2.2t / m 3 ~2.7t / m 3 ), due to the increase in the specific gravity of the material, the point where the material falls when it leaves the belt becomes closer, and the parabola of the material is as follows Fig.10 As shown, at this time, the two sets of first push rods 2-1 on the upper part can be extended at the same time, and the second push rod 2-2 on the lower part can be actuated at the same time to adjust the angle of the baffle 1 to ensure that the material falls at the center of the lower belt.

Compared with the prior art, the utility model has the following advantages: 1. The layout is simple, the parts are simple to make, and the practicability is strong; 2. It is all driven by an electric push rod, and no manual adjustment is required, which greatly saves manpower and can be operated by one person; 3. Adjustments can be made while working without stopping the work, which improves the working efficiency. On the other hand, the adjustment operation is more intuitive during the operation, and there is no need to stop the machine frequently to find the appropriate angle and position; 4. The adjustment of the baffle angle is also completed by an electric push rod, which does not require stopping the machine, and can be adjusted while working, which is intuitive and efficient to operate; 5. This solution innovatively allows the baffle to be tilted left and right, so that the baffle can achieve full-dimensional and multi-directional angle adjustment; 6. The baffle of this solution can be infinitely moved on the outer support of the funnel through the bearing seat, covering more working conditions and with higher adjustment accuracy; 7. This solution has side baffles welded on both sides of the center baffle to prevent materials from slipping from both sides of the adjustment baffle and make the materials more concentrated.

[0064] The above are only preferred implementations of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions under the concept of the present utility model belong to the protection scope of the present utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present utility model should be regarded as the protection scope of the present utility model.
