Description

A discharging structure of a belt conveyor Technical Field

[0001] The invention belongs to the technical field of breeding equipment and relates to a discharging structure of a belt conveyor. Background Art

[0002] Currently, biological treatment technology uses breeding equipment to breed insects. The insects on the breeding equipment will eventually grow into mature insects of appropriate size by ingesting and digesting food nutrients. The insects and insect excrement harvested from the breeding equipment can be further processed to obtain high-quality organic fertilizer.

[0003] Existing conventional belt conveyor structures, such as the patent document discloses a scraping device for a material-discharging conveyor belt (application number: 202121206847.7), which includes a base and a belt (i.e., a conveyor belt). A transmission mechanism is provided on the base, and the transmission mechanism is connected to the belt transmission. A mounting frame is fixedly installed on one side of the base directly below the belt, and a scraper is fixedly installed inside the mounting frame, and the scraper is in extrusion contact with the surface of the belt, and a transition plate is provided parallel to the bottom of the scraper. When the belt conveyor is used for insect breeding, although the scraper can be used to scrape off residual materials, feces, dirt and impurities, thereby helping to keep the conveyor belt clean and hygienic, the belt conveyor structure still has some shortcomings: the breeding equipment usually has multiple layers of upper and lower belt conveyors, and the insects grow gradually as they pass through each layer of belt conveyors in turn. During the breeding process, each layer of belt conveyor usually stays for a period of time, such as 24 hours, for the insects to eat, and then transported to the next layer of belt conveyor to continue feeding. However, since the two ends of the belt conveyor lack a blocking structure, insects may crawl out from both ends of the conveyor belt or materials may fall out of the conveyor belt during the conveyor belt's stay, which may cause many troubles to production.

[0004] Summary of the Invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a discharging structure for a belt conveyor. The technical problem solved by the present invention is: how to make the belt conveyor have the dual functions of scraping and blocking materials through a relatively simple structure.

[0006] The objectives of the present invention can be achieved through the following technical solutions: a discharging structure of a belt conveyor, the belt conveyor including a mounting bracket and a conveyor belt arranged on the mounting bracket, characterized in that the discharging structure includes a baffle plate that can be positioned on the upper side of the end of the conveyor belt to block the material on the top surface of the conveyor belt, and the baffle plate is hingedly connected to the mounting bracket; the baffle plate can be flipped downward along the surface of the conveyor belt and positioned at a position lower than the top surface of the conveyor belt, and when the baffle plate is in this position, its side close to the conveyor belt is in contact with the surface of the conveyor belt.

[0007] This belt conveyor can be used for insect farming operations on a breeding line. Specifically, during insect farming, nutrients and insects are placed on the top surface of the conveyor belt. The insects feed and grow on the stationary conveyor belt. At this time, the baffle plate is positioned on the upper side of the conveyor belt end, which can prevent the insects from crawling out of the conveyor belt end and also prevent nutrients from falling from the conveyor belt end. When the material on the conveyor belt (mainly insects, excrement, and residual nutrients) needs to be transported off, the baffle plate is flipped down and positioned at a scraping position below the top surface of the conveyor belt. At the same time, the conveyor belt begins to rotate. At this time, the baffle plate loses its material blocking function, allowing the material to fall out of the conveyor belt end through the baffle plate, thus realizing the transfer and transportation of the material. Moreover, since the baffle plate is in the scraping position and is close to the side of the conveyor belt and is in contact with the surface of the conveyor belt, the baffle plate has a scraping function during the process of rotating the conveyor belt to transfer and transport materials, and can scrape off residual materials, feces, dirt and impurities on the surface of the conveyor belt, thereby helping to keep the conveyor belt clean and hygienic.

[0008] The belt conveyor's discharging mechanism features a clever design that allows the baffle to switch between different functional modes, making it a dual-purpose device. Compared to conventional structures with separate baffles and scrapers, this belt conveyor's structure reduces the number of components required in the overall design, achieving a simplified and compact structure. Furthermore, reducing the number of components also reduces material and storage costs, among other cost factors, thereby achieving reasonable cost control.

[0009] In the above-mentioned belt conveyor discharging structure, a rotatable drive roller is horizontally provided at the end of the mounting bracket, the end of the conveyor belt is sleeved on the drive roller, and the baffle plate can be turned up and down around the drive roller, and when the baffle plate is turned to any position, its side close to the conveyor belt can always be in contact with the surface of the conveyor belt. Belt conveyors usually have drive rollers at both ends of the mounting bracket, and the leading and trailing ends of the conveyor belt are respectively sleeved on the drive rollers at both ends of the mounting bracket. When the motor drives the drive rollers to rotate, the conveyor belt can rotate synchronously with the drive rollers. After the conveyor belt is sleeved on the drive rollers, the surface of the conveyor belt at the drive rollers is a circular arc surface. At this time, because the baffle plate can be turned up and down around the drive rollers, that is, the axis of the drive roller is the rotation centerline of the baffle plate, so that during the baffle plate's turning process and when it is turned upward to the material blocking state, its side close to the conveyor belt can always be in contact with the surface of the conveyor belt. This can prevent the situation where material leaks out of the gap between the baffle plate and the conveyor belt, resulting in material waste and poor material blocking effect.

[0010] In the above-mentioned discharging structure of the belt conveyor, the baffle plate is in the shape of an elongated plate, and the length direction of the baffle plate is consistent with the width direction of the conveyor belt. The discharging structure also includes a driving assembly and two connecting plates. The two connecting plates are rotatably arranged at the two ends of the driving roller, and the driving assembly can drive one of the connecting plates to rotate around the driving roller. The two ends of the baffle plate are respectively connected to the two connecting plates. By setting two connecting plates to install the baffle plate, the baffle plate is easy to install and has high installation stability. The connecting plate is rotatably set on the driving roller. This structure uses the driving roller to realize the installation of the connecting plate without the need for an additional rotating shaft for installing the connecting plate, thereby achieving the effect of saving the number of parts and simplifying the structure. The baffle plate is in the shape of an elongated plate, so that the baffle plate has the advantages of easy manufacturing and low manufacturing cost on the basis of ensuring good baffle and scraping effects.

[0011] In the above-mentioned discharging structure of the belt conveyor, the mounting bracket includes two parallel side panels, the upper edges of the two side panels are higher than the top surface of the conveyor belt, the two side edges of the conveyor belt are respectively in contact with the inner side walls of the two side panels, the connecting plate is located on the outside of the side panels, and the ends of the baffle plate respectively have narrow strip-shaped extensions, the inner sides of the extensions form avoidance gaps for the ends of the side panels to enter when the baffle plate is flipped upward, and the ends of the baffle plate are respectively connected to the two connecting plates via the extensions. The two ends of the driving roller are respectively rotatably connected to the two side panels. When the baffle plate is flipped upward, the ends of the side panels can enter the avoidance gaps, so that the connecting plate can be arranged on the outside of the side panels to connect with the baffle plate. The connecting plate is located on the outside of the side plate, so that the connecting plate will not block the conveyor belt and the side plate, thereby ensuring that both sides of the conveyor belt can fit with the inner walls of the two side plates, so that the side plates also have a good material blocking effect, and then use the side plates to prevent materials from falling from both sides of the conveyor belt, and also prevent insects from crawling out from both sides of the conveyor belt.

[0012] In the above-mentioned belt conveyor discharging structure, the side of the baffle plate closest to the conveyor belt is the inner side, and the extensions at both ends of the baffle plate are connected to the corresponding connecting plates via adjustment assemblies. The adjustment assembly includes a fixed block fixedly connected to the inner side wall of the connecting plate and an adjustment block fixedly connected to the extension. The adjustment block is screwed to the fixed block via an adjustment bolt. By rotating the adjustment bolt, the distance between the adjustment block and the fixed block can be changed, thereby adjusting the distance between the inner side of the baffle plate and the drive roller. When the adjustment bolt is rotated, the adjustment block can be driven to rotate relative to the fixed block, thereby adjusting the distance between the fixed block and the adjustment block, and further adjusting the distance between the inner side of the baffle plate and the drive roller. Of course, the adjustment of this distance is usually relatively small. Since the conveyor belt passes between the inner side of the baffle plate and the drive roller, the above-mentioned adjustment can change the fit between the baffle plate and the conveyor belt surface, preventing the baffle plate from being too tightly pressed against the conveyor belt surface, resulting in excessive friction, and also preventing the baffle plate from being too tightly fitted to the conveyor belt surface, resulting in a gap.

[0013] In the above-mentioned discharging structure of the belt conveyor, the adjusting block is located on the side of the fixed block facing away from the avoidance gap, the axial direction of the adjusting bolt is perpendicular to the axial direction of the driving roller, the rod of the adjusting bolt passes through the adjusting block and is threadedly connected to the fixed block, the head of the adjusting bolt abuts against the end face of the adjusting block facing away from the fixed block, and the adjusting bolt is also provided with a spring compressed between the adjusting block and the fixed block.

[0014] The axis of the adjusting bolt is perpendicular to the axis of the drive roller. Rotating the adjusting bolt drives the adjusting block and the material retaining plate radially along the drive roller, adjusting the distance between the inner edge of the material retaining plate and the drive roller for optimal contact with the conveyor belt surface. During rotation of the adjusting bolt, the spring constantly supports the adjusting block, preventing it from wobbling and enhancing the feel of adjustment.

[0015] In the above-mentioned discharging structure of the belt conveyor, the discharging structure further includes two symmetrically arranged guide plates, the two guide plates are respectively fixed to the inner side walls of the two side plates, the distance between the two guide plates gradually decreases along the conveying direction of the conveyor belt, a limit rod arranged along the width direction of the conveyor belt is fixed between the tops of the outer ends of the two guide plates, and when the baffle plate is flipped upward to a vertical state, one side surface can abut against the limit rod and the side surface serves as the working surface of the baffle plate. The distance between the two guide plates gradually decreases along the conveying direction of the conveyor belt, so that an upper guide channel with a gradually narrowing opening is formed between the two guide plates, thereby guiding the materials on the left and right sides of the conveyor belt to the middle of the conveyor belt, so that after the baffle plate swings downward, the materials can all pass through the baffle plate and fall into the next process, without falling out of the baffle plate due to the avoidance gaps at both ends of the baffle plate, causing waste of materials. By setting a limit rod, the upward turning stroke of the material blocking plate can be limited, so that the material blocking plate can be stably positioned at the material blocking position, improving the stability and reliability of the equipment. The limit rod is connected between the top of the outer ends of the two guide plates, so that a space is formed below the limit rod for the material to pass through.

[0016] In the above-mentioned belt conveyor discharging structure, a clearance groove is formed between each guide plate and the inner wall of the adjacent side plate. Two guide bars are fixedly connected to the working surface of the baffle plate. The two guide bars are symmetrically arranged at both ends of the baffle plate. The distance between the two guide bars gradually decreases from one end near the inner side edge of the baffle plate to the other end. When the baffle plate is flipped upward to a vertical position, the guide bars can enter the clearance groove on the same side. The distance between the two guide bars gradually decreases from one end near the inner side edge of the baffle plate to the other end, forming a lower-level guide channel with a gradually narrowing opening between the two guide bars. This can control the flow of material and prevent material from escaping from the clearance gaps at both ends of the baffle plate, causing material waste. Because the guide plates are tilted, a clearance groove is formed between each guide plate and the inner wall of the adjacent side plate. When the baffle plate is flipped upward to a vertical position, the clearance groove is just large enough for the guide bars to enter, allowing the baffle plate to be accurately and smoothly reset. Therefore, this design enables the conveyor belt to have the functions of blocking and scraping materials, and also enables the conveyor belt's discharge structure to form upper and lower layers of material guide channels to well control the flow direction of materials, thereby achieving better discharge effects.

[0017] In the above-mentioned belt conveyor discharging structure, the connecting plate is perpendicular to the drive roller, one end of which is connected to the drive roller via a bearing. The drive assembly includes a fixed base, a cylinder, and a rack. The rack is arranged along the length of the conveyor belt. A gear that is rotatably mounted on the drive roller is fixed to the side of one of the connecting plates. The rack meshes with the gear and is slidably connected to the fixed base along its length. The cylinder can drive the rack to slide relative to the fixed base. One end of the connecting plate is connected to the drive roller via a bearing, ensuring stable installation and rotation of the connecting plate. The piston rod of the cylinder is fixed to the rack, allowing the cylinder to move the rack, thereby driving the gear and the connecting plate to rotate synchronously, causing the material retaining plate to flip up and down. Furthermore, the piston rod of the cylinder can be maintained in either an outwardly extended or inwardly retracted state. Unless the piston rod of the cylinder is extended or retracted, the material retaining plate does not swing on its own. This ensures that the material retaining plate is positioned both when it swings upward to a vertical position and when it swings downward to a scraping position below the top surface of the conveyor belt. This discharging structure drives the baffle plate to swing through the cylinder, and has the advantages of high degree of automation and stable operation.

[0018] In the above-mentioned discharging structure of the belt conveyor, the mounting bracket includes two side plates arranged in parallel. The discharging structure also includes two connecting plates perpendicular to the driving rollers. The two connecting plates are rotatably arranged at the two ends of the driving rollers, and the two ends of the baffle plate are respectively connected to the two connecting plates. The inner side of the connecting plate is provided with a mounting plate fixedly connected to the side plate in parallel. A pin hole is provided on the connecting plate, and a retractable upper limit pin and lower limit pin are provided on the mounting plate; when the baffle plate is flipped upward to a vertical state, the upper limit pin can be extended into the pin hole; when the baffle plate is flipped downward to a position lower than the top surface of the conveyor belt, the lower limit pin can be extended into the pin hole. This method involves manually flipping the baffle up and down. When the baffle is needed to block material, it is simply flipped upward to a vertical position. The upper limit pin now aligns with and can be inserted into the pin hole, positioning the baffle in the blocking position to block material on the top surface of the conveyor belt. When material is needed to be discharged, the baffle is simply flipped downward to a position below the top surface of the conveyor belt. The lower limit pin now aligns with and can be inserted into the pin hole, positioning the baffle. At this point, the baffle loses its blocking function, allowing material to fall outward from the end of the conveyor belt through the baffle, achieving material transfer and transportation. Manually flipping the baffle has the advantages of low cost and good reliability.

[0019] Compared with the existing technology, the discharging structure of this belt conveyor has the following advantages:

[0020] 1. The discharging structure of this belt conveyor can be switched to different functional modes through the ingenious design of the baffle plate, so that the baffle plate has a dual function. Compared with the conventional structure with a baffle plate and a scraper plate set separately, the structure of this belt conveyor can reduce the number of parts required in the overall design, thereby achieving the purpose of simplifying the structure and the effect of compact structure.

[0021] 2. The improvement of the discharging structure can realize the dual functions of scraping and blocking with fewer parts, thereby reducing the material cost of parts, storage cost and other cost factors, making the discharging structure have the advantage of low cost.

DETAILED DESCRIPTION

[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0034] Example 1

[0035] As shown in Figures 1 and 2, the discharging structure of the belt conveyor includes a mounting bracket 1 and a conveyor belt 2 mounted on the mounting bracket 1. The belt conveyor has rotatable drive rollers 4 horizontally arranged at both ends of the mounting bracket 1. The head and tail ends of the conveyor belt 2 are respectively sleeved on the drive rollers 4 at both ends of the mounting bracket 1. When the motor drives the drive rollers 4 to rotate, the conveyor belt 2 can rotate synchronously with the drive rollers 4. In Figures 1 and 2, the complete conveyor belt 2 and mounting bracket 1 structure are not shown. The discharging structure includes a baffle plate 3 that can be positioned on the upper side of the end of the conveyor belt 2 to block the material on the top surface 21 of the conveyor belt 2. The baffle plate 3 is hingedly connected to the mounting bracket 1. The baffle plate 3 can be flipped downward along the surface of the conveyor belt 2 and positioned at a position lower than the top surface 21 of the conveyor belt 2. When the baffle plate 3 is in this position, its side close to the conveyor belt 2 is in contact with the surface of the conveyor belt 2.

[0036] As shown in Figures 1 and 2, after the conveyor belt 2 is sleeved on the driving roller 4, the surface of the conveyor belt 2 at the driving roller 4 is an arc surface, and the baffle plate 3 can be flipped up and down around the driving roller 4, that is, the axis of the driving roller 4 is the rotation center line of the baffle plate 3, so that when the baffle plate 3 is flipped to any position, its side close to the conveyor belt 2 can always be in contact with the surface of the conveyor belt 2, so as to avoid the situation where there is a gap between the baffle plate 3 and the conveyor belt 2, and the material leaks from the gap, causing material waste and poor blocking effect.

[0037] As shown in Figures 2 and 3, the baffle plate 3 is in the shape of a long strip, and the length direction of the baffle plate 3 is consistent with the width direction of the conveyor belt 2. The discharging structure also includes a driving component and two connecting plates 5. The two connecting plates 5 are respectively rotatably arranged at the two ends of the driving roller 4. The driving component can drive one of the connecting plates 5 to rotate around the driving roller 4, and the two ends of the baffle plate 3 are respectively connected to the two connecting plates 5.

[0038] As shown in Figures 1 and 3, the mounting bracket 1 includes two parallel side panels 1a, the upper edges of the two side panels 1a are higher than the top surface 21 of the conveyor belt 2, and the two sides of the conveyor belt 2 are respectively in contact with the inner side walls of the two side panels 1a. The connecting plate 5 is located on the outer side of the side panels 1a, and the two ends of the material blocking plate 3 are respectively provided with narrow strip extensions 31. The inner sides of the extensions 31 are formed with avoidance notches 32 for the ends of the side panels 1a to enter when the material blocking plate 3 is turned upward. The two ends of the material blocking plate 3 are respectively connected to the two connecting plates 5 by the extensions 31. The connecting plate 5 is located on the outer side of the side panels 1a, so that the connecting plate 5 will not be blocked between the conveyor belt 2 and the side panels 1a, thereby ensuring that the two sides of the conveyor belt 2 can be in contact with the inner side walls of the two side panels 1a, so that the side panels 1a also have a good material blocking effect, thereby preventing material from falling from the two sides of the conveyor belt 2 by using the side panels 1a, and also preventing insects from crawling out from the two sides of the conveyor belt 2.

[0039] As shown in Figures 4 and 5, the side of the baffle plate 3 close to the conveyor belt 2 is the inner side 33. The extensions 31 at both ends of the baffle plate 3 are connected to the corresponding connecting plate 5 through an adjustment assembly. The adjustment assembly includes a fixed block 6 fixedly connected to the inner side wall of the connecting plate 5 and an adjustment block 7 fixedly connected to the extension 31. The adjustment block 7 is screwed to the fixed block 6 via an adjustment bolt 8. By rotating the adjustment bolt 8, the distance between the adjustment block 7 and the fixed block 6 can be changed, thereby fine-tuning the distance between the inner side 33 of the baffle plate 3 and the driving roller 4. Specifically, as shown in Figure 5, the adjustment block 7 is located on the side of the fixed block 6 facing away from the avoidance gap 32. The axial direction of the adjustment bolt 8 is perpendicular to the axial direction of the driving roller 4. The rod of the adjustment bolt 8 passes through the adjustment block 7 and is threadedly connected to the fixed block 6. The head of the adjustment bolt 8 abuts against the end face of the adjustment block 7 facing away from the fixed block 6. The adjustment bolt 8 is also sleeved with a spring 9 compressed between the adjustment block 7 and the fixed block 6. When the adjusting bolt 8 is rotated, the adjusting block 7 is driven to rotate relative to the fixed block 6, thereby adjusting the spacing between the fixed block 6 and the adjusting block 7, and further adjusting the distance between the inner side 33 of the baffle plate 3 and the drive roller 4. Of course, the adjustment of this distance is usually relatively small. Such adjustment can change the fit between the baffle plate 3 and the surface of the conveyor belt 2, preventing the baffle plate 3 from being too tightly pressed against the surface of the conveyor belt 2, thereby preventing excessive friction, and also preventing the baffle plate 3 from being too tightly pressed against the surface of the conveyor belt 2, thereby preventing the formation of gaps between the baffle plate 3 and the surface of the conveyor belt 2.

[0040] As shown in Figure 2, the discharging structure also includes two symmetrically arranged guide plates 10, which are respectively fixed to the inner walls of the two side plates 1a. The distance between the two guide plates 10 gradually decreases along the conveying direction of the conveyor belt 2. A limiting rod 11 arranged along the width direction of the conveyor belt 2 is fixed between the tops of the outer ends of the two guide plates 10. When the baffle plate 3 is flipped upward to a vertical state, one of its side surfaces can be against the limiting rod 11 and this side surface is the working surface 34 of the baffle plate 3. An avoidance groove 18 is formed between each guide plate 10 and the inner wall of the adjacent side plate 1a. Two guide strips 12 are fixedly connected to the working surface 34 of the baffle plate 3. The two guide strips 12 are symmetrically arranged at both ends of the baffle plate 3. The distance between the two guide strips 12 gradually decreases from one end close to the inner side edge 33 of the baffle plate 3 to the other end. As shown in Figure 1, when the baffle plate 3 is flipped upward to a vertical state, the guide strips 12 can enter the avoidance groove 18 on the same side.

[0041] As shown in Figure 2, the distance between the two guide plates 10 gradually decreases along the conveying direction of the conveyor belt 2, forming an upper guide channel with a gradually narrowing opening between the two guide plates 10. The distance between the two guide strips 12 gradually decreases from one end near the inner edge 33 of the baffle plate 3 to the other end, forming a lower guide channel with a gradually narrowing opening between the two guide strips 12. Therefore, this design not only enables the conveyor belt 2 to have both the baffle and scraper functions, but also enables the conveyor belt 2's discharge structure to form upper and lower guide channels to effectively control the flow of materials, resulting in a better discharge effect.

[0042] As shown in Figures 6, 7, and 8, the connecting plate 5 is perpendicular to the driving roller 4. One end of the connecting plate 5 is connected to the driving roller 4 via a bearing 13. The driving assembly includes a fixed base 14, a cylinder 15, and a rack 16. The rack 16 is parallel to the length direction of the conveyor belt 2. A gear 17 rotatably mounted on the driving roller 4 is fixedly connected to the side of one of the connecting plates 5. The rack 16 meshes with the gear 17. The rack 16 is slidably connected to the fixed base 14 along its length, and the cylinder 15 can drive the rack 16 to slide relative to the fixed base 14. The cylinder 15 pushes the rack 16 to move, driving the gear 17 and the connecting plate 5 to rotate synchronously, thereby realizing the up and down flipping of the baffle plate 3.

[0043] During the actual operation of the equipment, an extension command is sent to the cylinder 15, so that the piston rod of the cylinder 15 extends outward, driving the baffle plate 3 to flip upward until the working surface 34 of the baffle plate 3 abuts against the limit rod 11, as shown in Figure 1. At this time, the piston rod of the cylinder 15 can remain in the extended position and will not automatically retract, thereby stably positioning the baffle plate 3 on the upper side of the end of the conveyor belt 2 to block the material on the top surface 21 of the conveyor belt 2; when it is necessary to flip the baffle plate 3 downward, it is only necessary to send a retraction command to the cylinder 15, so that the piston rod of the cylinder 15 automatically retracts and remains in the retracted position, thereby driving the baffle plate 3 to flip downward and position it below the top surface 21 of the conveyor belt 2. At this time, the baffle plate 3 loses its baffle function, allowing the material to fall outward from the end of the conveyor belt 2 through the baffle plate 3, realizing the transfer and transportation of the material.

[0044] This belt conveyor is mainly used for insect farming on breeding equipment. Specifically, when carrying out insect farming, nutrients and insects are placed on the top surface 21 of the conveyor belt 2. The insects feed and grow on the stationary conveyor belt 2. At this time, as shown in Figure 1, the baffle plate 3 is in a vertical state, which can prevent the insects from crawling out from the end of the conveyor belt 2 and also prevent the nutrients from falling from the end of the conveyor belt 2. When the material on the conveyor belt 2 (mainly insects, excrement and residual nutrients) needs to be transported out, the baffle plate 3 is flipped downward to the scraping position as shown in Figure 2. When the baffle plate 3 is in the scraping position, it is lower than the scraping position of the top surface 21 of the conveyor belt 2. At the same time, the conveyor belt 2 starts to rotate. At this time, the baffle plate 3 loses its blocking function, allowing the material to fall outward from the end of the conveyor belt 2 through the baffle plate 3, thereby realizing the transfer and transportation of the material. Moreover, since the baffle plate 3 is close to the side of the conveyor belt 2 and fits the surface of the conveyor belt 2 when it is in the scraping position, the baffle plate 3 has a scraping function during the process of rotating the conveyor belt 2 to transfer and transport materials. It can scrape off residual materials, feces, dirt and impurities on the surface of the conveyor belt 2, thereby helping to keep the conveyor belt 2 clean and hygienic.

[0045] Example 2

[0046] The structure and principle of this embodiment are basically the same as those of the first embodiment, except that: as shown in Figures 9 and 10, a mounting plate 19 fixedly connected to the side plate 1a is provided parallel to the inner side of the connecting plate 5, a pin hole 51 is provided on the connecting plate 5, and a retractable upper limit pin 20 and a lower limit pin 21 are provided on the mounting plate 19; as shown in Figure 9, when the baffle plate 3 is flipped upward to a vertical state, the upper limit pin 20 can extend into the pin hole 51; as shown in Figure 10, when the baffle plate 3 is flipped downward to a position lower than the top surface 21 of the conveyor belt 2, the lower limit pin 21 can extend into the pin hole 51.

[0047] This method is to manually operate the material baffle plate 3 to flip up and down. When the material baffle plate 3 needs to be used to block the material, it is only necessary to manually flip the material baffle plate 3 upward to a vertical state. At this time, the upper limit pin 20 is opposite to the pin hole 51 and can be inserted into the pin hole 51, thereby positioning the material baffle plate 3 in the material blocking position, so that the material baffle plate 3 can block the material on the top surface 21 of the conveyor belt 2; when it is necessary to discharge the material, it is only necessary to manually flip the material baffle plate 3 downward to a position lower than the top surface 21 of the conveyor belt 2. At this time, the lower limit pin 21 can be opposite to the pin hole 51 and inserted into the pin hole 51 to position the material baffle plate 3. At this time, the material baffle plate 3 loses its material blocking function, allowing the material to fall outward from the end of the conveyor belt 2 through the material baffle plate 3, thereby realizing the transfer and transportation of the material.

[0048] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
