Description

Technical Field

[0001] The present application relates to the technical field of conveyor belts, and in particular to a conveyor belt discharging anti-splash mechanism. Background Art

[0002] A conveyor belt, also known as a belt conveyor, is mainly used to convey various solid lumps, powdered materials or finished items. The conveyor belt can transport continuously, efficiently, at a large inclination angle, and is safe to operate, easy to use, and can save a large amount of manpower and material resources. Therefore, conveyor belts are widely used in agriculture, industrial and mining enterprises, transportation and logistics industries.

[0003] During the process of grain processing and transportation, conveyor belts are usually used. Grain has a certain inertial potential energy during transportation on the conveyor belt. Therefore, the grain will be thrown out in a parabola when discharging, resulting in grain splashing. When the transported grain is mixed with dust, it will cause dusting, polluting the processing environment. Utility Model Content

[0004] In order to improve the problem of grain splashing during discharging, which causes dusting and pollutes the processing environment, the present application provides a conveyor belt discharging anti-splash mechanism.

[0005] A conveyor belt discharging anti-splash mechanism provided by the present application adopts the following technical solutions:

[0006] A conveyor belt discharging anti-splash mechanism includes a conveyor belt body, a material receiving plate and a pressing member. The conveyor belt body includes a frame, rotating rollers and a conveyor belt. A plurality of the rotating rollers are rotatably connected to the frame, and the conveyor belts are jointly wound around the rotating rollers; the material receiving plate is obliquely connected to the frame at the discharging end of the conveyor belt body, and the highest point of the material receiving plate is located below the conveyor belt; a cross bar is arranged on the frame above the conveyor belt along the width direction of the conveyor belt, and the pressing member is connected to the cross bar, and the pressing member can abut against the conveyor belt at the discharging end of the conveyor belt body.

[0007] By adopting the above technical solutions, during use, the rotating rollers rotate to drive the conveyor belt to move, and materials such as grain are thrown out from the conveyor belt at the discharging end of the conveyor belt body. The thrown materials are blocked by the pressing member and cannot be thrown out. The materials and the dust mixed therein abut against the pressing member and fall on the material receiving plate, and then the materials slide down along the material receiving plate; the cooperation setting of the pressing member and the material receiving plate can block the throwing of materials and prevent dusting, improve the problem of grain splashing during discharging, which causes dusting and pollutes the processing environment, and has a simple structure and is convenient to use.

[0008] Optionally, the pressing member is made of cloth, and the pressing member is laid on the conveyor belt at the discharging end of the conveyor belt body and extends to the upper surface of the material receiving plate.

[0009] By adopting the above technical solution, after the material is thrown out on the conveyor belt at the discharge end of the conveyor belt body, it will contact the pressing member of the fabric product. On the one hand, it prevents the material from splashing when it is thrown out. On the other hand, the pressing member of the fabric product will adsorb the ash layer doped on the material and can also play a role in cleaning the material.

[0010] Optionally, the pressing member includes a pressing plate and a shielding plate. One end of the pressing plate is rotatably connected to the cross bar around the axial direction of the cross bar. A gap for the material to pass through is left between the pressing plate and the upper surface of the conveyor belt. A fixing component for fixing the pressing plate is provided on the cross bar; the shielding plate is rotatably connected to the end of the pressing plate away from the cross bar, and the rotation axis of the shielding plate is parallel to the axis of the cross bar. A channel for the material to fall is formed between the shielding plate and the conveyor belt.

[0011] By adopting the above technical solution, during use, adjust the rotation angle of the pressing plate so that only a gap for the material to pass through is left between the pressing plate and the upper surface of the conveyor belt, and then fix the pressing plate through the fixing component. At this time, the shielding plate naturally hangs down under its own gravity, and a channel for the material to fall is formed between the shielding plate and the conveyor belt. The material passes through the gap between the pressing plate and the upper surface of the conveyor belt and then falls into the material receiving plate from the channel; the combined action of the pressing plate and the shielding plate can prevent the material from splashing when it is thrown out, and by adjusting the distance between the pressing plate and the upper surface of the conveyor belt, the falling amount of the material can be adjusted. The structure is simple and easy to use.

[0012] Optionally, the fixing component includes a fixing disk, a ratchet wheel, a ratchet pawl and an elastic member. The ratchet wheel is fixedly connected to the pressing plate, and the axis of the ratchet wheel coincides with the axis of the cross bar; the fixing disk is coaxially connected to the cross bar, and one end of the ratchet pawl is rotatably connected to the fixing disk; one end of the elastic member is connected to the fixing disk, and the other end of the elastic member is connected to the ratchet pawl. The elastic member makes the ratchet pawl tend to move and be clamped between the teeth of the ratchet wheel.

[0013] By adopting the above technical solution, when it is necessary to increase the gap between the pressing plate and the conveyor belt, directly rotate the pressing plate upward to drive the ratchet wheel to rotate upward; when the position of the pressing plate is adjusted in place, under the elastic force of the elastic member, the ratchet pawl is clamped between the teeth of the ratchet wheel, so that the ratchet wheel cannot rotate downward, thereby fixing the angle of the pressing plate; the structure is simple and easy to use.

[0014] Optionally, a rotating rod is vertically and fixedly connected to the fixing disk. The rotating rod passes through the ratchet pawl, and the rotating rod is rotatably connected to the ratchet pawl through a bearing. A fastening bolt is threadedly connected to the end of the rotating rod that passes through the ratchet pawl.

[0015] By adopting the above technical solution, after the angle of the pressing plate is adjusted in place, to prevent the abnormal rotation of the ratchet pawl from releasing the locking of the ratchet wheel, the fastening bolt can be tightened so that the fastening bolt presses against the ratchet pawl, thereby locking the ratchet pawl, and the structure is simple and practical.

[0016] Optionally, adsorption brushes are provided on both sides of the pressing plate and the shielding plate close to the conveyor belt.

[0017] By adopting the above technical solution, the setting of the adsorption brush enables impurities such as ash layers doped in the material to be adsorbed on the adsorption brush when materials such as grains pass through, thereby playing a role in cleaning the material.

[0018] Optionally, handles are provided on both sides of the pressing plate and the shielding plate away from the conveyor belt.

[0019] By adopting the above technical solution, the setting of the handle can facilitate the force application to turn over the pressing plate and the shielding plate.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. The cooperative setting of the material receiving plate and the pressing member enables the material to be blocked by the pressing member after being thrown out from the conveyor belt at the discharge end of the conveyor belt body, so that the material cannot be thrown out in a parabolic shape. The material blocked by the pressing member falls onto the material receiving plate under the action of gravity and then slides down along the material receiving plate, improving the problem that the grain splashes during discharging, causing dust pollution to the processing environment;

[0022] 2. The pressing member is made of cloth products, and the self-gravity of the cloth products covers the upper surfaces of the conveyor belt and the material receiving plate, so that the material is located below the pressing member during transportation. On the one hand, it restricts the material from being thrown out in a parabolic shape, and on the other hand, it can also clean the impurities doped in the material. The material source of the pressing member is easy to obtain and the cost is low;

[0023] 3. The combination setting of the pressing plate, the shielding plate and the fixing component enables, during use, only to rotate the pressing plate so that the gap between the pressing plate and the conveyor belt only allows the material to pass through, and then fix the pressing plate through the fixing component. At this time, the shielding plate naturally hangs down under its own gravity, and the material falls onto the material receiving plate through the channel between the shielding plate and the conveyor belt after passing through the gap between the pressing plate and the conveyor belt, preventing the material from being thrown out and splashing during discharging; the setting of the fixing component enables the distance between the pressing plate and the upper surface of the conveyor belt to be adjustable and fixed, thereby playing a role in adjusting the feeding amount of the material.

Detailed implementation manners

[0029] The following will Figures 1-3 further describe the present application in detail.

[0030] Embodiment 1:

[0031] The embodiment of the present application discloses a splash-proof mechanism for the discharge of a conveyor belt. Refer to Figure 1 , the splash-proof mechanism for the discharge of the conveyor belt includes a conveyor belt body 1, a material receiving plate 2, and a pressing member 3.

[0032] The conveyor belt body 1 includes a frame 11, rotating rollers 12, a conveyor belt 13, and a rotating motor 14. There are multiple rotating rollers 12, and the multiple rotating rollers 12 are all rotatably connected to the frame 11 in the transverse direction. The conveyor belt 13 is jointly wound around the circumferential wall of the rotating rollers 12, and the upper surface of the conveyor belt 13 is used for transporting materials such as grains. The rotating motor 14 is bolted and fixed to the frame 11, and the rotating motor 14 drives the rotating rollers 12 to rotate through a sprocket 15 and a chain 16.

[0033] The material receiving plate 2 is fixedly welded to the frame 11 at the discharging end of the conveyor belt body 1. The material receiving plate 2 is inclined downward at a depression angle of 10° to 45°, and preferably 20° in this application. The highest point of the material receiving plate 2 is located below the conveyor belt 13. The materials thrown out from the conveyor belt 13 at the discharging end of the conveyor belt body 1 will fall on the upper surface of the material receiving plate 2 and then slide down along the upper surface of the material receiving plate 2. The materials falling from the conveyor belt 13 land on the material receiving plate 2, reducing the falling height of the materials and the risk of material splashing.

[0034] A cross bar 4 is fixedly welded to the frame 11 along the width direction of the conveyor belt 13. Exemplarily, the pressing member 3 is made of cloth. One end of the pressing member 3 is tied to the cross bar 4 by a thin string. The side of the pressing member 3 away from the cross bar 4 abuts against the upper surface of the conveyor belt 13 and extends all the way to the upper surface of the material receiving plate 2.

[0035] The implementation principle of the anti-splash mechanism for the conveyor belt discharging in this application embodiment is as follows: during use, start the rotating motor 14 and then drive the rotating roller 12 to rotate through the sprocket 15 and the chain 16, driving the conveyor belt 13 to move. The materials thrown out from the conveyor belt 13 will not be thrown out in a parabolic shape under the blocking action of the pressing member 3, preventing the materials from splashing when falling, and improving the problem of grain splashing during discharging, causing dust pollution to the processing environment. And when the materials move on the material receiving plate 2, by contacting the cloth pressing member 3, the impurities such as ash layers doped in the materials are adsorbed on the pressing member 3, playing a role in cleaning the materials.

[0036] Embodiment 2:

[0037] The embodiment of this application discloses an anti-splash mechanism for conveyor belt discharging. The difference between the second embodiment of this application and the first embodiment of this application is that, referring to Figure 2 , the pressing member 3 includes a pressing plate 31 and a shielding plate 32. One end of the pressing plate 31 is rotatably connected to the cross bar 4 around the axis of the cross bar 4. The length of the pressing plate 31 is greater than the length from the cross bar 4 to the end of the discharging end of the conveyor belt 13. A gap for material transportation to pass through is left between the pressing plate 31 and the upper surface of the conveyor belt 13. A fixing component 5 for locking the pressing plate 31 is arranged on the cross bar 4. The shielding plate 32 is rotatably connected to one end of the pressing member 3 away from the cross bar 4. The rotation axis of the shielding plate 32 is parallel to the axis of the cross bar 4. The shielding plate 32 naturally hangs down under its own gravity, and a material falling channel will be formed between the shielding plate 32 and the conveyor belt 13.

[0038] When in use, the pressure plate 31 is rotated to adjust the gap between the pressure plate 31 and the upper surface of the conveyor belt 13, thereby regulating the flow rate of the material passing through the gap between the pressure plate 31 and the upper surface of the conveyor belt 13. When the pressure plate 31 is adjusted to the right position, the fixing component 5 is used to limit the pressure plate 31 from rotating downward, thereby locking the pressure plate 31. After the material passes through the gap between the pressure plate 31 and the upper surface of the conveyor belt 13, it falls onto the receiving plate 2 along the channel between the shielding plate 32 and the conveyor belt 13. The setting of the pressure plate 31 can not only block the material from being thrown out and prevent the material from splashing, but also regulate the flow rate of the material when it is discharged to a certain extent. It has a simple structure and is easy to use.

[0039] In addition, in order to clean the impurities such as dust mixed in the material when the material is moving, the side of the pressure plate 31 and the shielding plate 32 close to the conveyor belt 13 is provided with an adsorption brush 33, and the impurities such as dust are adsorbed after contacting the adsorption brush 33, thereby reducing the probability of the dust splashing and polluting the processing environment. In order to facilitate the rotation of the pressure plate 31 and the shielding plate 32, the side of the pressure plate 31 and the shielding plate 32 away from the conveyor belt 13 is provided with a handle 34.

[0040] Reference Figure 3 The fixing assembly 5 includes a fixing plate 51, a ratchet 52, a pawl 53 and an elastic member 54. The ratchet 52 is welded and fixed on the pressure plate 31. The axis of the ratchet 52 coincides with the axis of the cross bar 4. The ratchet 52 is an internal tooth ratchet 52. The fixing plate 51 is coaxially welded and fixed on the cross bar 4. A rotating rod 55 is vertically welded and fixed on the fixing plate 51. The rotating rod 55 is passed through the pawl 53. The pawl 53 is rotatably connected to the rotating rod 55 through a bearing. An external thread is provided on the outer peripheral wall of one end of the rotating rod 55 passing through the pawl 53. A tightening nut 56 is threadedly connected to the external thread section of the rotating rod 55. The pawl 53 can be pressed against the fixing plate 51 by tightening the tightening nut 56, so that the pawl 53 is locked and cannot rotate. The elastic member 54 is an elastic card, one end of the elastic member 54 is connected to the fixed plate 51, and the other end of the elastic member 54 is connected to the pawl 53. The elastic member 54 makes the pawl 53 have a movement tendency to be engaged between the teeth of the ratchet 52; when the pawl 53 is engaged between the teeth of the ratchet 52, the ratchet 52 can be locked and cannot rotate downward.

[0041] The implementation principle of the anti-splash mechanism for the conveyor belt discharge in the embodiments of this application is as follows: during use, appropriately rotate the pressure plate 31 to adjust the distance between the pressure plate 31 and the conveyor belt 13, so as to adjust the flow rate of the material output from the gap between the pressure plate 31 and the conveyor belt 13. When the position of the pressure plate 31 is adjusted in place, the pawl 53 is clamped between the teeth of the ratchet wheel 52 under the elastic force of the elastic member 54, so that the ratchet wheel 52 is locked, and the pressure plate 31 cannot rotate downward. The material output from the gap between the pressure plate 31 and the conveyor belt 13 then falls onto the material receiving plate 2 through the channel formed between the baffle plate 32 and the conveyor belt 13 and slides down along with the material receiving plate 2. In order to prevent the pressure plate 31 from rotating upward under force during the output process of the material, only need to tighten the fastening nut 56. During the falling process, the material contacts the adsorption brush 33, and the adsorption brush 33 adsorbs impurities such as ash layers doped in the material, playing a role in cleaning the material.

[0042] The above are all optional embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
