Description

Technical Field

[0001] The utility model relates to the technical field of unloading device equipment, in particular to a uniform unloading device and a transmission system thereof. Background Art

[0002] In the mining industry, stone conveying systems typically transport stone to the top of a warehouse via conveyor belts, where it is then unloaded and placed inside. Traditional stone conveying systems utilize automated equipment for intelligent adjustments during the transportation phase to ensure smooth and normal operation. However, during the unloading phase, the stone is often simply and directly unloaded through a discharge channel on a platform connected to the end of the conveyor belt.

[0003] In the above-mentioned solution, since the position of the unloading channel is relatively fixed, the stones can only naturally form a pile structure after falling, and the top of the pile structure is close to the unloading channel. However, due to differences in stone particle size and shape, as well as fluctuations in parameters such as conveyor belt speed and inclination, it is easy to cause the amount of stone unloaded at each moment to be inconsistent, which in turn causes uneven distribution of stones in the storage bin, that is, the formed stone pile becomes deformed, and localized excessive accumulation and voids may form in the stone pile. In this case, on the one hand, it causes waste of warehouse space utilization, and on the other hand, it may affect the subsequent safe removal of stones, thereby hindering subsequent processing. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a uniform unloading device, which allows users to adjust the position where stones fall, etc., to ensure that the stone pile structure formed in the warehouse is relatively normal and stable, thereby improving the utilization efficiency of the warehouse.

[0005] The utility model is realized through the following technical solutions:

[0006] A uniform unloading device is characterized in that it comprises: a main base, a material channel opening is provided at the center of which is used to allow material to fall through; an adjusting turntable, installed at the bottom of the main base, comprising a first driving part and a turntable body, a unloading port connected to the material channel opening is provided at the center of the turntable body, and the first driving part is used to drive the turntable body to rotate around its center; a unloading guide part is used to guide the unloading direction of the material, comprising a unloading channel, an initial guiding end of the unloading channel is placed at the bottom of the unloading port, and a terminal guiding end of the unloading channel is farther away from the turntable body than the initial guiding end.

[0007] In traditional stone conveying systems, stones tend to form a cone-shaped stone pile after falling, and the top of such a stone pile is close to the discharge port. The structure of the stone pile easily causes the warehouse space near its top to be wasted.

[0008] In the present invention, after passing through the material channel and the discharge port in sequence, the stone falls onto the initial guide end of the discharge channel. Subsequently, because the final guide end is farther away from the turntable body than the initial guide end, the stone slides toward the final guide end under the influence of gravity and finally falls. Under the structure of this unloading device, the user can drive the turntable body to rotate so that the stone falls from different lowering positions, and a cone-like stone pile structure will not be generated, so that the warehouse space is fully utilized. At the same time, the user can adjust the lowering position of the stone to make up for the vacancies in the stone pile while observing the overall structure of the stone pile. This makes the formation of the stone pile based on the stacking of relatively flat stone layers, avoiding the generation of cavities in the stone pile, and facilitating the subsequent safe removal of stones from the warehouse.

[0009] As a further improvement of the present invention, the unloading guide part also includes a retractable device, the initial guide end is movably connected to the turntable body, and the final guide end is connected to the edge of the turntable body through the retractable device, and the retractable device is used to control the retractable height of the final guide end.

[0010] Under this structure, the optional lowering positions of the stones are further increased. Specifically, when the rear guide end descends, the stones can be lowered to the bottom near the discharge port; when the guide end rises, the stones can be lowered to the bottom away from the discharge port.

[0011] As a further improvement of the present invention, the retracting and releasing device includes at least two chains and a winch for retracting and releasing the chains, wherein the winch is installed at the bottom of the turntable body, one end of the chain is connected to the winch, and the other end is connected to the unloading channel.

[0012] As a further improvement of the present invention, a limiting member is provided at the bottom of the turntable body. When the last guide end is retracted to the highest point, the limiting member conflicts with the unloading channel. The limiting member can ensure that the last guide end will not be lifted excessively and collide with the retracting device during the retraction process.

[0013] As a further improvement of the present invention, the unloading channel includes a main unloading channel and an auxiliary unloading channel, the initial guide end is arranged on the main unloading channel, and the final guide end is arranged on the auxiliary unloading channel. The auxiliary unloading channel is movably installed on the unloading channel through a second driving part, and the second driving part is used to control the auxiliary unloading channel to slide along the unloading guide path of the unloading channel.

[0014] Under this structure, the optional lowering positions of the stones are further increased. In particular, when the auxiliary unloading channel slides along the unloading guide path of the unloading channel and extends out of the main unloading channel, the overall length of the unloading channel is actually increased, thereby making it possible to lower the stones to a position farther away from the unloading port.

[0015] As a further improvement of the present invention, a monitoring device is provided on the discharge channel. The monitoring device can be provided on both sides or ends of the discharge channel, etc., for facilitating the user to observe the overall structure of the stone pile below.

[0016] As a further improvement of the present invention, the monitoring device is disposed on both sides of the last guide end of the discharge channel. In particular, when the discharge channel includes a main discharge channel and an auxiliary discharge channel, the last guide end is disposed on the last guide end of the auxiliary discharge channel. Thus, the monitoring device can more directly observe the stacking of the stones at the lowering position of the channel as the auxiliary discharge channel moves, thereby providing the user with an accurate basis for adjusting the status of the discharge device.

[0017] As a further improvement of the present invention, the monitoring device further includes a lighting device.

[0018] As a further improvement of the present invention, the cross-sectional area of ​​the material passing through the discharge port is larger than the cross-sectional area of ​​the material passing through the material passage port, thereby further preventing the stone from being obstructed when falling to the initial guide end.

[0019] In a second aspect, the utility model provides a transmission system, comprising a transmission belt and the above-mentioned uniform unloading device, wherein the uniform unloading device is arranged at the transmission end of the transmission belt.

[0020] The beneficial effect of the present invention is that the uniform unloading device can facilitate users to adjust the lowering position of stones to form a more reasonable stone pile structure in the warehouse. On the one hand, it improves the utilization rate of the warehouse space. On the other hand, it ensures that the hollow or excessive accumulation of the formed stone pile structure is greatly reduced, which is conducive to the safe removal of stones in subsequent production steps and will not affect the smooth progress of subsequent processing steps.

Figure 2 The auxiliary unloading channel 301-2 is shown in its extended state, which can increase the overall length of the unloading channel 301, facilitate transporting the stones to a position further away from the unloading port 201-1, and increase the number of stone lowering positions of the uniform unloading device.

[0034] Preferably, Figure 3 As shown, a monitoring device 4 is provided on the unloading channel 301. In this embodiment, the monitoring device 4 is provided on both sides of the end guide end 301b on the auxiliary unloading channel 301-2, which will not hinder the falling of the stone. At the same time, it can facilitate the user to observe the stone accumulation situation at the current stone lowering position to determine whether to continue to lower the stone here.

[0035] Preferably, the monitoring device 4 also includes a lighting device.

[0036] Preferably, Figure 1 As shown in the figure, the material passing cross-sectional area of ​​the discharge port 201-1 is larger than the material passing cross-sectional area of ​​the material passage port 101, ensuring that, especially during the rotation of the turntable body 201, the stones can also smoothly pass through the material passage port 101 and the discharge port 201-1 in sequence.

[0037] Preferably, in this embodiment, the first driving unit, the second driving unit, the retracting device 302 and the monitoring device 4 are all linked to the control device, so that the working state of the uniform unloading device can be understood and adjusted through the unified control device.
