Description

Technical Field

[0001] The present application relates to the technical field of bio-based material processing, and in particular to a conveying device for bio-based materials. Background Art

[0002] Bio-based materials refer to a new type of material that is manufactured using renewable biomass, such as crops, trees, algae, fungi, etc., through biological, chemical and physical methods. These materials have the advantages of wide sources, environmental friendliness and good biocompatibility. During the production process, they need to be transported to connect various processing equipment and improve processing efficiency.

[0003] Patent No. CN 218967909 U discloses a conveying device for bio-based materials, including a conveying roller, a protruding strip, a separator and a rotating wheel, etc. The rotation of the first rotating wheel is used to drive the two conveying rollers and the transmission belt arranged on the support frame to move simultaneously, and a partition is arranged between the two conveying rollers to facilitate the simultaneous conveying of two bio-based materials of different specifications. When the rotating wheel rotates, it will drive the docking block to move. The rotating wheel and the docking block form a structure similar to an eccentric wheel. The rotation of the rotating wheel is used to make the first mesh plate and the second mesh plate shake up and down, thereby screening the bio-based materials and achieving the effect of screening and conveying at the same time. By adjusting the movable wheel on the rotating wheel, the movable wheel drives the connecting screw to rotate, thereby allowing the sliding block and the docking block to move on the rotating wheel to adjust the distance between the docking block and the rotating wheel. By adjusting different distances, the vibration amplitude of the first mesh plate and the second mesh plate is adjusted to increase its practicality.

[0004] However, in use, there are the following defects:

[0005] Although the rotation of the rotating wheel is used to vibrate the upper mesh plate to screen the bio-based materials, after the vibration is completed, larger bio-based materials will still remain on the surface of the first mesh plate and cannot pass through the limit plate, so they will accumulate on the surface of the first mesh plate, which is more troublesome to clean and may even block the pores of the first mesh plate, affecting subsequent screening. Utility Model Content

[0006] The purpose of the present application is to provide a conveying device for bio-based materials, which solves the problem proposed in the background technology that although the rotation of the rotating wheel is used to vibrate the upper mesh plate to screen the bio-based materials, after the vibration is completed, larger bio-based materials will still remain on the surface of the first mesh plate and cannot pass through the limit plate, so they will accumulate on the surface of the first mesh plate, which is troublesome to clean and may even block the pores of the first mesh plate, affecting subsequent screening.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a conveying device for bio-based materials, comprising a base, a screening trough, a pumping pipe and a conveyor belt, characterized in that a temporary storage bin is fixedly installed on the left side of the top end of the base, the lower end of the pumping pipe passes through the top end of the temporary storage bin and is located at the lower part of the interior of the temporary storage bin, the upper end of the pumping pipe is located above the left side of the screening trough, and an air flow pump is fixedly connected to the middle section of the exhaust pipe, a bottom support frame and a high support frame are fixedly installed on the rightmost side of the top end of the base, the front and rear surfaces of the left side of the screening trough are movably connected to the inner side wall of the bottom support frame through a support shaft, and a rotating rod is rotatably connected between the inner walls of the high support frame, Three cams are fixedly connected to the surface of the rotating rod, and the rear side of the bottom of the screening slot is movably supported on the surface of the cam, the left end of the screening slot is located at the opening of the right side wall of the temporary storage bin, and two transmission rollers are rotatably connected between the front and rear inner walls of the screening slot, and the surfaces of the transmission rollers are transmission-connected with a conveyor belt, and two strip grooves are provided at the inner bottom of the screening slot, and screening nets are detachably installed on the surfaces of the two strip grooves, and a No. 3 motor is fixedly installed at the bottom of the screening slot between the two strip grooves, and the outer end of the transmission shaft of the No. 3 motor passes through the bottom of the screening slot and is fixedly connected to the rotating shaft, and a connecting rod is fixedly welded to the side wall of the rotating shaft, and a soft rubber strip is fixedly connected to the outer end of the connecting rod.

[0008] In this technical solution, bio-based materials are added to the temporary storage bin through the filling port, and the bio-based materials can be continuously screened through the pumping pipe, air flow pump, conveyor belt, screening trough and screening net. After the air flow pump is started, the bio-based materials in the temporary storage bin are pumped out along the pumping pipe and guided to the conveyor belt in the screening trough. After the No. 2 motor is powered on, it drives the transmission roller to rotate, and the conveyor belt moves to the right side of the screening trough with the bio-based materials, and finally reaches the right side of the conveyor belt and slides out, falls into the screening trough, slides down in the screening trough, and passes through the screening net according to the pores of the screening net when passing by. The bio-based materials that have not had time to pass through will return to the temporary storage bin along the screening trough, and then continue to perform the above steps. The bio-based materials can be screened continuously for a long time without human intervention, which improves the screening efficiency of the device. During the screening process, motor No. 1 starts to drive the rotating rod and cam to rotate. The cam will lift the screening slot during rotation and then drop it, thereby vibrating the screening slot and facilitating the screening of bio-based materials. At the same time, motor No. 3, rotating shaft, connecting rod and soft rubber strip can prevent the screening net from being blocked. When the screening stops, motor No. 3 starts to drive the rotating shaft and connecting rod to rotate, and the soft rubber strip will rotate along the surface at the inner bottom of the screening slot to sweep out the bio-based materials stuck on the screening net, and cooperate with the cam to vibrate the screening slot, thereby reducing the blockage of the screening net by bio-based materials and ensuring the continuous screening ability of the device.

[0009] As an optional solution of the technical solution of the present application, a material discharge frame is fixedly connected to the bottom of the screening trough outside the lower opening of the strip trough, and a corresponding conveyor belt is opened below the material discharge frame.

[0010] As an optional solution of the technical solution of the present application, a filling port is provided on the side wall of the temporary storage bin.

[0011] As an optional solution of the technical solution of the present application, a No. 1 motor is fixedly installed on the outer side wall of the high support frame facing one end of the rotating rod, and the outer end of the transmission shaft of the No. 1 motor passes through the high support frame and is fixedly connected to the rotating rod.

[0012] As an optional solution to the technical solution of the present application, a No. 2 motor is fixedly installed on the outer wall of the screening slot facing the outer end of the left driving roller inside the screening slot, and the outer end of the drive shaft of the No. 2 motor passes through the outer wall of the screening slot and is fixedly connected to the driving roller.

[0013] As an optional solution of the technical solution of the present application, the front and rear inner side walls of the screening trough are fixedly connected with side baffles, and the bottom of the side baffles is in contact with the surface of the conveyor belt.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present application can continuously screen bio-based materials through a pumping pipeline, an air flow pump, a conveyor belt, a screening trough and a screening net. After the air flow pump is started, the bio-based materials in the temporary storage bin are pumped out along the pumping pipeline and guided to the conveyor belt in the screening trough. After the No. 2 motor is powered on, it drives the transmission roller to rotate, and the conveyor belt moves to the right side of the screening trough with the bio-based materials, and finally reaches the right side of the conveyor belt and slides out, falls into the screening trough, slides down in the screening trough, and passes through the screening net according to the pores of the screening net when passing by, and the bio-based materials that do not have time to pass through will return to the temporary storage bin along the screening trough, and the above steps can be continued, so that the bio-based materials can be continuously screened for a long time without manual intervention, thereby improving the screening efficiency of the device.

[0016] 2. The present application can prevent the clogging of the screening net through the No. 3 motor, the rotating shaft, the connecting rod and the soft rubber strip. When the screening stops, the No. 3 motor starts to drive the rotating shaft and the connecting rod to rotate, and the soft rubber strip will rotate along the surface at the inner bottom of the screening slot to sweep out the bio-based materials stuck on the screening net, and cooperate with the vibration of the screening slot by the cam to reduce the clogging of the screening net by the bio-based materials, thereby ensuring the continuous screening ability of the device.

[0023] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, they are further explained below in conjunction with specific implementation methods.

[0024] like Figure 1 As shown, a conveying device for bio-based materials includes a base 1, a screening trough 9, a pumping pipe 3 and a conveyor belt 19. A temporary storage bin 2 is fixedly installed on the left side of the top of the base 1, and an air flow pump 4 is fixedly connected to the middle section of the exhaust pipe. The air flow pump 4 uses high-pressure air flow to generate low pressure, thereby forming a negative pressure to absorb materials. Specifically, the high-pressure air flow generated by the fan draws the material into the pump body through the pumping pipe 3. After the negative pressure is generated, the material is adsorbed on the internal partition plate and then transported to the outlet at the other end of the pumping pipe 3. This is a prior art, so it will not be described in detail. A low support frame 5 and a high support frame 6 are fixedly installed on the rightmost side of the top of the base 1. The low support frame 5 and the high support frame 6 make the screening trough 9 inclined, thereby facilitating the sliding of the bio-based material.

[0025] like Figure 1As shown, a rotating rod 7 is rotatably connected between the inner walls of the high support frame 6, and a No. 1 motor 701 is fixedly installed on the outer wall of the high support frame 6 facing one end of the rotating rod 7. The outer end of the transmission shaft of the No. 1 motor 701 passes through the high support frame 6 and is fixedly connected to the rotating rod 7. Three cams 8 are fixedly connected to the surface of the rotating rod 7, and the bottom rear side of the screening slot 9 is movably supported on the surface of the cam 8. The cam 8 continuously lifts the screening slot 9 when rotating, and then suddenly drops it, thereby vibrating the screening slot 9 to facilitate the screening of bio-based materials.

[0026] like Figure 2 As shown, a material discharge frame 18 is fixedly connected to the bottom of the screening slot 9 outside the lower opening of the strip slot 13, and a corresponding conveyor belt 19 is provided below the material discharge frame 18. The corresponding conveyor belts 19 do not affect each other, so that the screened bio-based materials are transported to the next processing area.

[0027] like Figure 1 and Figure 2 As shown, the left end of the screening trough 9 is located at the opening of the right side wall of the temporary storage bin 2, and two transmission rollers 10 are rotatably connected between the front and rear inner walls of the screening trough 9, and a No. 2 motor 101 is fixedly installed on the outer side wall of the screening trough 9 facing the outer end of the left transmission roller 10 inside the screening trough 9, and the outer end of the transmission shaft of the No. 2 motor 101 passes through the outer side wall of the screening trough 9 and is fixedly connected to the transmission roller 10, and the surface of the transmission roller 10 is transmission-connected with a conveyor belt 11, and the front and rear inner walls of the screening trough 9 are fixedly connected with side baffles 12, and the bottom of the side baffles 12 is in contact with the surface of the conveyor belt 11, and the side baffles 12 can block the gaps on both sides of the conveyor belt 11, so that the bio-based material can reach the right side of the screening trough 9 as much as possible.

[0028] like Figure 2 As shown, the lower end of the pumping pipe 3 passes through the top of the temporary storage bin 2 and is located at the lower part of the interior of the temporary storage bin 2 , and the upper end of the pumping pipe 3 is located above the left side of the screening tank 9 .

[0029] like Figure 3 As shown, the left front and rear surfaces of the screening tank 9 are movably connected to the inner wall of the low support frame 5 through the support shaft 501, and the side wall of the temporary storage bin 2 is provided with a filling port 201.

[0030] like Figure 2 and Figure 4As shown, two strip grooves 13 are provided at the inner bottom of the screening slot 9, and screening nets 14 are detachably installed on the surfaces of the two strip grooves 13, and a No. 3 motor 151 is fixedly installed at the bottom of the screening slot 9 between the two strip grooves 13, and the outer end of the transmission shaft of the No. 3 motor 151 passes through the bottom of the screening slot 9 and is fixedly connected to the rotating shaft 15, and a connecting rod 16 is fixedly welded to the side wall of the rotating shaft 15, and a soft rubber strip 17 is fixedly connected to the outer end of the connecting rod 16, and the soft rubber strip 17 rotates along the inner bottom of the screening slot 9, thereby sweeping out the bio-based material stuck on the surface of the screening net 14, so that it slides down back into the temporary storage bin 2.

[0031] In actual use, bio-based materials are added to the temporary storage bin 2 through the filling port 201. After the airflow pump 4 is started, the bio-based materials in the temporary storage bin 2 are pumped out along the pumping pipe 3 and guided to the conveyor belt 11 in the screening slot 9. After the No. 2 motor 101 is powered on, it drives the transmission roller 10 to rotate, and the conveyor belt 11 moves to the right side of the screening slot 9 with the bio-based materials, and finally reaches the right side of the conveyor belt 11 and slides out, falls into the screening slot 9, slides down in the screening slot 9, and passes through the screening net 14 according to the pores of the screening net 14 when passing through, and the bio-based materials that have not had time to pass through will return to the temporary storage bin 2 along the screening slot 9, and the above steps can be continued, so that the bio-based materials can be screened continuously for a long time without manual intervention, thereby improving the screening efficiency of the device. During the screening process, the No. 1 motor 701 is started to drive the rotating rod 7 and cam 8 rotate. During the rotation, cam 8 will lift up the screening slot 9 and then smash it down, so that the screening slot 9 vibrates, which is convenient for the screening of bio-based materials. Sometimes the screening net 14 will be blocked by the bio-based materials. At this time, the conveyor belt 11 and the air pump 4 are closed to temporarily stop the transportation. The third motor 151 is started to drive the rotating shaft 15 and the connecting rod 16 to rotate. The soft rubber strip 17 will rotate along the surface of the inner bottom of the screening slot 9 to sweep out the bio-based materials stuck on the screening net 14, and cooperate with the vibration of the screening slot 9 by the cam 8, thereby reducing the blockage of the screening net 14 by the bio-based materials, ensuring the continuous screening ability of the device. The screened bio-based materials fall along the unloading frame 18 onto the corresponding conveyor belt 19 and leave, entering the area of ​​the next processing step, and the bio-based materials that have not passed through the screening net 14 can be taken out through the warehouse door on the front side wall of the temporary storage bin 2.
