[0002] The dual-branch chute (1) and material conveying flap (3) switching device at the phosphogypsum filter discharge outlet are part of the phosphogypsum filtration and discharge conveying system. Its upper portion is connected to the filter discharge hopper, and its lower portion corresponds to two belt conveyors. Switching flaps changes the phosphogypsum conveying path, delivering the filtered filter cake to the corresponding belt conveyors. The currently used dual-branch chute material conveying flap switching device has several problems during use:
[0003] 1. The thickness of the flap is small, which leads to an increase in the frequency of flap damage, increases the frequency of maintenance, and increases production costs. If the thickness of the flap is increased or the material with higher hardness is changed, the flap itself will be heavier and cannot be switched under the impact force of the material.
[0004] 2. The current flap mechanism is difficult to quickly realize the flip of the flap, and the impact force of the material easily causes the flap to automatically switch, causing the conveying path to be disordered and blocked, affecting the stable operation of production.
[0005] In summary, how to provide a flap mechanism that can quickly switch heavy flaps is an urgent problem to be solved by those skilled in the art. Utility Model Content
[0006] In view of this, the purpose of the present invention is to provide a double-branch chute flap switching mechanism that can quickly switch heavy-weight flaps and ensure the stability of the flaps during operation.

[0019] Furthermore, in the present invention, the switching member can be a manual hoist crane or an electric hoist crane.
[0020] Furthermore, in the present invention, there are two switching members and two switching rods, which are respectively located at two ends of the flap shaft, and the two switching members are respectively connected to different ends of the two switching rods.
[0021] Furthermore, in the present invention, the switching rod adopts a telescopic structure.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0032] The core of the utility model is to provide a double-branch chute flap switching mechanism, which can quickly switch heavy-weight flaps and ensure the stability of the flaps during operation.
[0033] Please refer to Figure 1-Figure 3 A double-branch chute flap switching mechanism includes a chute 1, a flap shaft 2, a flap 3 and a switching mechanism 4. The chute 1 includes a feed port and two discharge ports, and is distributed in an inverted Y-shaped structure. The flap shaft 2 is rotatably installed on the chute 1 and is located at the intersection of the two discharge ports. The flap 3 is located inside the chute 1 and is fixed on the flap shaft 2. The switching mechanism 4 is used to change the force arm required to rotate the flap shaft 2.
[0034] It should be noted that, in the embodiment of the present invention, the material of the flap 3 can be selected according to the use environment, and the thickness of the flap can also be selected according to the use environment.
[0035] Optionally, in order to increase the service life of the flap shaft 2, in some embodiments, a wear-resistant sleeve 5 is provided on the flap shaft 2 at the connection position between the flap shaft 2 and the chute 1. Specifically, the wear-resistant sleeve 5 can be replaced by a bearing. The wear-resistant sleeve 5 can be used to increase the service life of the flap shaft 2, and can effectively reduce the force acting on the rotation of the flap shaft 2 when the flap is subjected to material impact, which is conducive to further increasing the rotation efficiency of the flap 3.
[0036] When in use, the flap shaft 2 is rotated and installed at the intersection of the two discharge ports on the chute 1, and the flap 3 is installed on the flap shaft 2. The chute 1 includes a feed port and two discharge ports, and is distributed in an inverted Y-shaped structure. The switching mechanism 4 is installed on the chute 1 and is used to change the force arm required for rotating the flap shaft 2. When it is necessary to adjust the flow direction of the material, the force arm required for rotating the flap shaft 2 is increased through the switching mechanism 4. The switching of the flap 3 can be achieved with a smaller force, and the switching speed is improved. After increasing the required force arm, the flap 3 can be made of a thickened stainless steel flap 3, which can reduce the frequency of maintenance and increase the stability of production. After increasing the force arm, the working position of the flap 3 can be fixed more stably, avoiding the switching of the flap 3 caused by the impact of the material, saving a lot of manpower caused by the heavy weight of the flap 3, and saving costs.
[0037] Please refer to Figure 1-Figure 3 In some embodiments, the switching mechanism 4 includes a switching rod 401, which is installed at the end of the flip shaft 2 extending out of the chute 1. That is, the switching rod 401 is installed at the end of the flip shaft 2, and the switching rod 401 is set vertically to the flip shaft 2. The switching rod 401 is used to increase the force arm of the flip shaft 2 during the flipping process, thereby satisfying the purpose of flipping the flip shaft 2 with less force.
[0038] Optionally, in some embodiments, the switching rod 401 is arranged perpendicular to the flap 3. The switching rod 401 arranged perpendicular to the flap 3 can have the same rotation circumference when rotating on both sides of the flap 3, which is convenient for controlling the flap 3, and when the flap 3 has material impact, the switching rod 401 has the same resistance.
[0039] Optionally, in some embodiments, the switching rod 401 may be connected between the end portion and the end portion of the flap shaft 2 , or the middle portion of the switching rod 401 may be connected to the end portion of the flap shaft 2 .
[0040] Optionally, in order to further enhance the force arm of the flip shaft and ensure the storage of the switching rod 401, in some embodiments, a connecting ring is provided at the end of the flip shaft 2, and the switching rod 401 is inserted into the connecting ring. When the flip shaft 2 is rotated in different directions, the switching rod 401 is pulled and biased to one end, thereby ensuring the enhancement of the force arm of the flip shaft and facilitating the storage of the switching rod 401.
[0041] In other embodiments, the switch rod 401 adopts a retractable structure. Specifically, the switch rod 401 adopts a retractable rod. When the flip axis needs to be rotated, it is extended to ensure the lifting of the flip axis force arm while facilitating the storage of the switch rod 401.
[0042] Please refer to Figure 2 In order to further facilitate the control of the switching rod 401, in some embodiments, the switching mechanism 4 also includes a switching member 402, which is installed on the chute 1 and is used to control the rotation of the switching rod 401. By manually controlling the switching member 402, the rotation of the flap shaft 2 can be achieved.
[0043] Optionally, in some embodiments, the switching member 402 may adopt a manual hoist or an electric hoist, that is, the hoist is used to reduce the force required to rotate the flap shaft 2 and reduce the strength of the worker to flip the flap 3.
[0044] In other embodiments, the switching member 402 can adopt a telescopic cylinder structure, such as an electric cylinder, a pneumatic cylinder or a hydraulic cylinder. When in use, one end of the switching member 402 is rotationally connected to the chute 1 and the other end is rotationally connected to the switching rod 401. The rotation control of the flap shaft 2 is achieved by the extension and retraction of the switching member 402.
[0045] Optionally, in some embodiments, there are two switching members 402 and two switching rods 401 , which are respectively located at two ends of the flap shaft 2 , and the two switching members 402 are respectively connected to different ends of the two switching rods 401 .
[0046] In other embodiments, the switching mechanism 4 can adopt a worm gear structure. Specifically, the switching mechanism 4 includes a worm gear and a worm. The worm gear is coaxially installed on the end of the flap shaft 2, and the worm is rotatably installed on the chute 1 and meshes with the worm gear. When the flap shaft 2 needs to be rotated, it is only necessary to rotate the worm to achieve the rotation of the flap shaft 2. The worm gear has the function of increasing the torque, thereby reducing the force acting on the rotation of the flip shaft.
[0047] Optionally, in order to reduce the possibility of logistics being stuck between the flap 3 and the side wall of the chute 1, in some embodiments, the cross-section of the end of the flap 3 away from the flap shaft 2 is an inverted V-shape, that is, a chamfer is set on the end face of the flap 3. When the flap 3 contacts the side wall of the chute 1, it is ensured that the chamfer position of the flap 3 is in close contact with the side wall of the chute 1, which can avoid logistics being stuck between the flap 3 and the side wall of the chute 1, thereby avoiding the need to stop the machine to clean up the accumulated materials, which is beneficial to improving production efficiency.
[0048] Optionally, in order to further reduce the amount of logistics stuck between the flap 3 and the side wall of the chute 1, in some embodiments, the chute 1 is provided with two baffles extending along the length direction of the flap 3, and the baffles are located above the contact position between the flap 3 and the chute 1, and the baffles are inclined toward the flap 3. That is to say, by providing an inclined baffle above the contact position between the flap 3 and the chute 1, the baffle has a diversion effect on the material and can completely prevent the material from entering between the flap 3 and the side wall of the chute 1.
[0049] That is to say, the focus of the embodiment of the present invention is to rotatably install the flap shaft 2 at the intersection of the two discharge ports on the chute 1, and install the flap 3 on the flap shaft 2. The chute 1 includes a feed port and two discharge ports, and is distributed in an inverted Y-shaped structure. The switching mechanism 4 is installed on the chute 1 and is used to change the force arm required for rotating the flap shaft 2. When it is necessary to adjust the flow direction of the material, the force arm required for rotating the flap shaft 2 is increased by the switching mechanism 4. The switching of the flap 3 can be achieved with a smaller force, and the switching speed is improved. After increasing the required force arm, the flap 3 can be made of a thickened stainless steel flap 3, which can reduce the frequency of maintenance and increase the stability of production. After increasing the force arm, the working position of the flap 3 can be fixed more stably, avoiding the switching of the flap 3 caused by the impact of the material, saving a lot of manpower caused by the heavy weight of the flap 3, and saving costs.

This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only intended to help understand the method and core concept of the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
