An automated feeding and transfer device for motor shafts

Abstract

This invention discloses an automated feeding and transfer device for motor shafts, including a feeding worktable and a feeding mechanism for transferring motor shafts. A material handling station is fixed on the feeding worktable, and two parallel baffles forming a hopper space are slidably connected to the worktable. A sliding frame is rotatably connected between the two baffles. This invention, by changing the tilt state of the sliding frame within the hopper space, can not only indicate the remaining amount of the shaft blanks but also facilitate accurate judgment by operators of the material distribution positions in the two subdivided spaces at the front and rear of the hopper. It can reflect the decreasing process of the remaining amount in the hopper space in real time and continuously. Furthermore, the two stages of decreasing remaining amount are simultaneously alerted by a warning mechanism to clearly identify the usage status of the shaft blanks in the hopper space, thereby highlighting the urgency of replenishment and prompting operators to replenish materials promptly, avoiding material shortages and machine shutdowns.

Description

Technical Field

[0001] This invention relates to the field of feeding device technology, specifically to an automated feeding and transfer device for a motor shaft. Background Technology

[0002] In the motor manufacturing process, the motor shaft is a core transmission component. Motor shaft production involves grinding and polishing the smooth shaft body. During the motor shaft processing, the loading and transfer is a key link connecting subsequent processing (such as grinding, polishing, and assembly). Existing motor shaft loading and transfer devices mostly include a hopper and a stepped loading mechanism. The hopper is used to store the motor shaft raw materials, and the stepped loading mechanism is responsible for orderly transferring the motor shafts in the hopper to the subsequent material picking station, where they are picked up by the robot arm and enter the next processing step.

[0003] However, existing silos are mostly divided into two connected storage areas. After the material in the rear section of the silo is discharged, the material in the front section is used to replace it. This relies heavily on on-site staff visually observing the remaining material in the silo. However, silos are mostly long and narrow, and the line of sight is easily obstructed by equipment, making it difficult for staff to accurately judge the remaining material and its distribution. It is also difficult to predict in advance when the material will run out, which can easily lead to situations where the silo is out of material before the problem is discovered. This can result in production interruptions, increased downtime, and waiting time. In addition, there is a certain waiting time for staff to respond to replenishment requests, which further prolongs the downtime and seriously affects production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an automated feeding and transfer device for motor shafts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automated motor shaft feeding and transfer device, comprising a feeding workbench and a feeding mechanism for transferring the motor shaft. A material handling station is fixed on the feeding workbench. Two parallel baffles forming a hopper space are slidably connected to the feeding workbench. A sliding frame is rotatably connected to the middle of the two baffles. A height-limiting plate is fixed to the inner wall of the baffle at the balance point of the sliding frame. The sliding frame is inclined downwards relative to the feeding mechanism. An emergency feeding mechanism is provided at the top of the two baffles. The emergency feeding mechanism includes a replenishment box fixed to the baffle at the hopper space dividing point. A replenishment port for feeding material onto the sliding frame is opened at the lower end of the replenishment box. A sealing plate is slidably connected to the replenishment port. A warning mechanism for early warning of the remaining motor shaft amount in the hopper space is fixed on one of the opposite sides of the two baffles. A transmission mechanism is provided between the warning mechanism and the sealing plate. The transmission mechanism drives the warning mechanism to issue a warning and open the replenishment port for automatic replenishment when the motor shaft in the hopper space is zeroed out.

[0006] By adopting the above technical solution, a small amount of motor shaft processed blanks are added to the replenishment box in advance when the machine is started, which is used for temporary replenishment after the blanks in the hopper space are emptied. The replenishment box is located at the dividing point of the silo space, dividing the silo space into two parts: the front section of the silo near the material picking station and the rear section of the silo away from the material picking station. The front section of the silo space is connected to the rear section of the silo space. The front section of the frame is located in the front section of the silo space, and the rear section of the frame is located in the rear section of the silo space.

[0007] When there is sufficient raw material in the rear section of the silo, the height of the front section of the frame is set to the height of point A. As the amount of raw material remaining in the rear space of the hopper decreases, the height of the front section of the frame decreases continuously, and the downward stroke squeezes the trigger plate, causing it to descend continuously. When the remaining material in the rear section of the hopper is emptied, the front section of the frame descends and presses the trigger plate to reach the lowest point. The height of the front section of the frame is set to point B. At this time, the warning mechanism issues the first warning. When the remaining material in the front section of the hopper is emptied, the trigger plate loses its load and rises back to its highest point. The height of the front section of the frame is set to point C. At this time, the warning mechanism issues a second warning. Simultaneously, the transmission mechanism drives the sealing plate to slide along the replenishment box to open the replenishment port, so that the shaft blank in the replenishment box falls to the sliding frame to realize emergency replenishment. This allows the device to continuously feed material during the replenishment waiting time in the hopper space, saving downtime caused by waiting for material replenishment. By observing the tilting state of the sliding rack within the hopper space, it is possible to indicate the remaining amount of shaft blanks and facilitate accurate judgment by staff regarding the material distribution in the two subdivided spaces at the front and rear of the hopper. This allows for real-time and continuous reflection of the decreasing amount of material in the hopper space. Furthermore, the simultaneous warnings from the two stages of decreasing amount, combined with the alert mechanism, clearly indicate the usage status of the shaft blanks in the hopper space, thereby highlighting the urgency of replenishment. This helps prompt staff to replenish materials promptly and avoid machine downtime due to material shortages.

[0008] Preferably, the slide rack is provided with a support mechanism, the support mechanism includes a connector fixed on the slide rack, the connector is provided with a rotating bracket for supporting the rotation of the slide rack, the lower end of the rotating bracket is fixed on the loading worktable, and the slide rack is fixed with a rotating shaft adapted to the rotation of the baffle.

[0009] By adopting the above technical solution, three sets of connectors are spaced apart between the two sliding rods, which can improve the stability of the connection between the two sliding rods in the sliding frame; the rotating bracket is set on the connector in the middle, which can support the sliding frame.

[0010] Preferably, the connector includes an extended inner rod that passes through and is fixed on the rotating bracket, and both ends of the extended inner rod are slidably sleeved with extended sleeves, which are inserted and fixed on the sliding frame.

[0011] The two ends of the extended inner rod are slidably sleeved with extended sleeves, so that the distance between the two sliding rods in the sliding frame can be adjusted to adapt to the width variation of the hopper space.

[0012] Preferably, the material handling rack includes a front section of the rack near the material handling station and a rear section of the rack away from the material handling station, wherein the height of the rear section of the rack is higher than that of the front section of the rack.

[0013] When the front section of the frame is at height C, the tilt angle of the sliding rack in the hopper is the smallest. The height limit plate supports the rear section of the frame from below to limit the minimum height, ensuring that the height of the rear section of the frame is always higher than the height of the front section, so that the shaft blank can slide down the inclined sliding rack to guide the material. When the front section of the frame is at height A, the tilt angle of the sliding rack in the hopper becomes larger. When the front section of the frame is at height B, the tilt angle of the sliding rack in the hopper is the largest.

[0014] Preferably, a first guide plate is fixed on the material handling station, and a second guide plate is fixed on the loading worktable between the first guide plate and the baffle. The loading mechanism includes a first lifting plate and a second lifting plate. The first lifting plate is slidably connected to the side of the second guide plate away from the first guide plate. The second lifting plate is slidably connected between the first guide plate and the second guide plate. A lifting frame is fixed between the first lifting plate and the second lifting plate. A driving component is fixed inside the loading worktable, and the output end of the driving component is connected to the lifting frame.

[0015] By adopting the above technical solution, during use, a small gap is provided between the first lifting plate and the baffle for sliding only, and the height of the end of the front section of the frame near the first lifting plate is higher than the initial height before the first lifting plate is raised; the width of the receiving surface of the first lifting plate is set between the diameter of one shaft blank and the diameter of two shaft blanks; in addition, the upper surfaces of the first lifting plate, the second guide plate, the second lifting plate and the first guide plate are all sloped, so that when the adjacent plate is raised to the specified height, the shaft blank slides down the slope of the front plate to the rear plate; the material picking station is provided with a slope opposite to the first guide plate, and a storage space for waiting for the robot to pick up the material is formed between the material picking station and the first guide plate.

[0016] Preferably, the replenishment box has a lifting guide groove on one side near the material picking station that is adapted to slide with the sealing plate, and the bottom wall of the replenishment box is sloping.

[0017] By adopting the above technical solution, the lifting guide groove can improve the accuracy of the sliding direction of the sealing plate; the bottom wall of the feeding box is sloping to facilitate the shaft blank to slide down and be discharged from the feeding port.

[0018] Preferably, the transmission mechanism includes a trigger plate slidably connected to the baffle, a connecting frame is fixed between the trigger plate and the sealing plate, and an elastic member for elastically supporting the trigger plate is fixed inside the baffle.

[0019] By adopting the above technical solution, the trigger plate and the elastic component work together to form an elastic support structure for the sliding frame. This elastic support structure can buffer the impact of the shaft blank falling from the feeding port.

[0020] Preferably, the elastic element includes a spring sleeve fixed inside the baffle, a telescopic slide column is slidably connected inside the spring sleeve, a lifting ring plate and a return spring are sleeved on the part of the telescopic slide column that extends into the spring sleeve, the lifting ring plate is fixed on the telescopic slide column, one end of the return spring is fixed on the end face of the lifting ring plate, and the other end of the return spring is fixed on the bottom wall of the spring sleeve.

[0021] By adopting the above technical solution, the two ends of the reset spring are respectively fixed between the lifting ring plate and the inner bottom wall of the spring sleeve, so that the telescopic slide can extend and retract inside the spring sleeve to ensure that the trigger plate has a good elastic buffering effect. When the remaining material in the front section of the hopper is emptied, the elastic deformation of the reset spring is restored, the trigger plate rises and resets, and the front section of the lifting frame reaches the height of point C. When the remaining material in the rear section of the hopper is sufficient, the front section of the frame reaches the height of point A, and the reset spring is compressed and deformed. When the remaining material in the rear section of the hopper is emptied, the front section of the frame reaches the height of point B, the trigger plate reaches the lowest point, and the reset spring is compressed and deformed to the maximum extent.

[0022] Preferably, the warning mechanism includes a first warning unit and a second warning unit. The first warning unit is fixed on a baffle, and the second warning unit is fixed on another baffle. A striking ball is fixed on the trigger plate. The first warning unit includes a first sound box fixed on a baffle, and a first sounding bell for striking the ball to produce sound is fixed inside the first sound box. The second warning unit includes a second sound box fixed on another baffle, and a second sounding bell for striking the ball to produce sound is fixed inside the second sound box.

[0023] By adopting the above technical solution, the second sounding bell is set at a higher height than the first sounding bell, the first sounding bell is set to a low-pitched warning sound, and the second sounding bell is set to a high-pitched warning sound; When there is sufficient raw material remaining in the rear section of the silo, the front section of the frame reaches height A without triggering a warning sound; when the remaining material in the rear section of the silo is emptied, the front section of the frame reaches height B, and the striking ball strikes the first sounding bell, triggering a low warning sound; when the remaining material in the front section of the silo is emptied, the lifting frame reaches height C, and the striking ball strikes the second sounding bell, triggering a sharp warning sound. On-site staff can distinguish different warning sounds by hearing, which allows them to quickly and easily understand the remaining quantity and distribution of materials in the silo without visual inspection. This improves the shortcomings of the narrow and long silo structure, which can easily obstruct the staff's view and reduces the trouble caused by unclear visual observation leading to unclear understanding of the remaining quantity and distribution of materials in the silo.

[0024] Preferably, the feeding workbench is fixed with a guide rail, and the lower end of the opposite side of the two baffles is fixed with a sliding plate that is adapted to slide with the guide rail. The sliding plate is threaded with fastening bolts for abutting against the guide rail.

[0025] By adopting the above technical solution, the two baffles adjust their spacing by sliding along the guide rail via a sliding plate, and the spacing is locked by the end of the fastening bolt screwed into the sliding plate and pressing against the guide rail.

[0026] This invention provides an automated feeding and transfer device for motor shafts, which has the following advantages compared with the prior art: By observing the tilting state of the sliding rack within the hopper space, it is possible to indicate the remaining amount of shaft blanks and facilitate accurate judgment by staff regarding the material distribution in the two subdivided spaces at the front and rear of the hopper. This allows for real-time and continuous reflection of the decreasing amount of material in the hopper space. Furthermore, the simultaneous warnings from the two stages of decreasing amount, combined with the alert mechanism, clearly indicate the usage status of the shaft blanks in the hopper space, thereby highlighting the urgency of replenishment. This helps prompt staff to replenish materials promptly and avoid machine downtime due to material shortages.

[0027] The emergency feeding mechanism and transmission mechanism enable the device to continuously feed materials while waiting for material replenishment in the silo space, saving downtime caused by waiting for material replenishment.

[0028] Through warning and transmission mechanisms, on-site staff can distinguish different warning sounds by hearing, allowing them to quickly and easily understand the remaining quantity and distribution of materials in the silo without visual inspection. This improves the shortcomings of narrow silo structures that easily obstruct the staff's view, reducing the trouble caused by unclear visual observation leading to ambiguity regarding the remaining quantity and distribution of materials in different areas.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-12This invention provides an automated feeding and transfer device for motor shafts, including a feeding workbench 1 and a feeding mechanism 3 for transferring motor shafts. A material handling station 11 is fixed on the feeding workbench 1. Two parallel baffles 2 forming a material storage space are slidably connected to the feeding workbench 1. A sliding frame 4 is rotatably connected to the middle of the two baffles 2. A height limiting plate 74 is fixed to the inner wall of the baffles 2 at the balance point of the sliding frame 4. The sliding frame 4 is inclined downwards relative to the feeding mechanism 3. An emergency feeding mechanism 6 is provided at the top of the two baffles 2. The feeding mechanism 6 includes a feeding box 61 fixed on the baffle 2 at the separation point of the hopper space. The lower end of the feeding box 61 is provided with a feeding port 63 for feeding material onto the sliding frame 4. A sealing plate 62 is slidably connected to the feeding port 63. A warning mechanism 8 for warning the remaining amount of the motor shaft in the hopper space is fixed on one side of the two baffles 2 facing away from each other. A transmission mechanism 7 is provided between the warning mechanism 8 and the sealing plate 62. The transmission mechanism 7 is used to drive the warning mechanism 8 to issue a warning and open the feeding port 63 for automatic feeding when the motor shaft in the hopper space is zeroed. When starting the machine, a small amount of motor shaft processed blanks are added to the replenishment box 61 in advance, which are used for temporary replenishment after the blanks in the hopper space are emptied. The replenishment box 61 is located at the dividing point of the silo space, dividing the silo space into two parts: the front section of the silo near the picking station 11 and the rear section of the silo away from the picking station 11; the front section of the silo space and the rear section of the silo space are connected; the front section of the frame 41 is located in the front section of the silo space, and the rear section of the frame 42 is located in the rear section of the silo space. When there is sufficient raw material remaining in the rear section of the silo, the height of the front section 41 of the frame is set to the height of point A (for reference). Figure 4 ); As the amount of raw material remaining in the rear space of the hopper decreases, the height of the front section 41 of the frame decreases continuously, and the downward stroke squeezes the trigger plate 72, causing it to continue to descend. When the remaining material in the rear section of the hopper is emptied, the front section 41 of the frame descends and presses against the trigger plate 72 to reach its lowest point. The height of the front section 41 of the frame is set to the height of point B (reference). Figure 5 At this point, warning device 8 issues an initial warning; When the remaining material in the front section of the hopper is emptied, the trigger plate 72 loses its load and will rise and reset to its highest point. The height of the front section 41 of the frame is set to the height of point C (reference). Figure 6 At this time, the warning mechanism 8 issues a second warning; at the same time, the transmission mechanism 7 drives the sealing plate 62 to slide along the replenishment box 61 to open the replenishment port 63, so that the shaft blank in the replenishment box 61 falls to the sliding frame 4 to realize emergency replenishment; so that the device can continue to feed materials during the material replenishment waiting time in the silo space, saving the downtime caused by waiting for material replenishment. The tilting state of the sliding rack 4 within the hopper space not only indicates the remaining amount of the shaft blanks, but also allows staff to accurately determine the material distribution in the two subdivided spaces at the front and rear of the hopper. It can reflect the decreasing process of the remaining amount in the hopper space in real time and continuously. Furthermore, the three stages of the decreasing amount, combined with the synchronous warning of the warning mechanism 8, clearly indicate the usage status of the shaft blanks in the hopper space, thereby clarifying the urgency of replenishing materials. This helps to prompt staff to replenish materials in a timely manner and avoid material shortages and machine shutdowns.

[0033] Please see Figure 7 and Figure 8 The slide rack 4 is provided with a support mechanism 5. The support mechanism 5 includes a connector 51 fixed on the slide rack 4. The connector 51 is provided with a rotating bracket 52 for supporting the rotation of the slide rack 4. The lower end of the rotating bracket 52 is fixed on the loading worktable 1. The slide rack 4 is fixed with a rotating shaft 53 that is adapted to the rotation of the baffle 2. The sliding frame 4 is mainly composed of two sliding rods, which are rotatably set in the rotating grooves on the inner side wall of the corresponding baffle 2 through corresponding T-shaped rotating shafts; three sets of connecting parts 51 are arranged between the two sliding rods to improve the stability of the connection between the two sliding rods in the sliding frame 4; the rotating bracket 52 is set on the connecting part 51 in the middle and can support the sliding frame 4.

[0034] Please see Figure 8 The connector 51 includes an extended inner rod 511 that passes through and is fixed on the rotating bracket 52. Both ends of the extended inner rod 511 are slidably sleeved with extended sleeves 512, and the extended sleeves 512 are inserted and fixed on the sliding frame 4. Among them, the two ends of the extended inner rod 511 are slidably sleeved with the extended sleeve 512, so that the distance between the two sliding rods in the sliding frame 4 is adjustable in order to adapt to the width variation of the hopper space.

[0035] Please see Figure 9 The material handling rack 4 includes a front section 41 near the material picking station 11 and a rear section 42 away from the material picking station 11. The height of the rear section 42 is higher than that of the front section 41. When the front section 41 of the frame is at height C (reference) Figure 6 When the tilt angle of the sliding frame 4 in the hopper is at its minimum, the height limit plate 74 supports the rear section 42 of the frame from below to limit the minimum height, ensuring that the height of the rear section 42 of the frame is always higher than the height of the front section 41 of the frame, so that the shaft blank can slide down the tilted sliding frame 4 for material guidance; when the front section 41 of the frame is at point A (reference point 41), the tilt angle of the sliding frame 4 is at its minimum. Figure 4 When the material conveyor 4 is in the hopper, the tilt angle of the material conveyor 4 increases; when the front section 41 of the frame is at point B height (reference point B), the tilt angle of the material conveyor 4 increases. Figure 5 When the material is in the hopper, the tilt angle of the material rack 4 is at its maximum.

[0036] Please see Figure 1-3 A first guide plate 12 is fixed on the material handling station 11, and a second guide plate 13 is fixed on the loading workbench 1 between the first guide plate 12 and the baffle 2. The loading mechanism 3 includes a first lifting plate 31 and a second lifting plate 32. The first lifting plate 31 is slidably connected to the side of the second guide plate 13 away from the first guide plate 12. The second lifting plate 32 is slidably connected between the first guide plate 12 and the second guide plate 13. A lifting frame 33 is fixed between the first lifting plate 31 and the second lifting plate 32. A driving component 34 is fixed inside the loading workbench 1. The output end of the driving component 34 is connected to the lifting frame 33. During loading, the shaft blank slides down from the rear section 42 of the frame to the front section 41 of the frame along the inclined sliding frame 4, and finally falls onto the first lifting plate 31. Then the drive component 34 is activated to drive the lifting frame 33 to rise. Among them, the driving component 34 is one of the following: hydraulic cylinder, air cylinder, electric push rod; The first lifting plate 31 and the second lifting plate 32 are combined into a lifting unit by the lifting frame 33; Among them, the upper surfaces of the first lifting plate 31, the second guide plate 13, the second lifting plate 32 and the first guide plate 12 are all sloping surfaces, so that when the adjacent plates are raised to a specified height, the shaft blank slides down the sloping surface of the front plate to the rear plate. Among them, a small gap is provided between the first lifting plate 31 and the baffle 2 for sliding only, and the height of the end of the front section 41 of the frame near the first lifting plate 31 is higher than the initial height of the first lifting plate 31 before it is raised. The width of the receiving surface of the first lifting plate 31 is set between the diameter of one shaft blank and the diameter of two shaft blanks; Among them, the material picking station 11 is provided with a sloping surface opposite to the first guide plate 12, and a storage space for waiting for the robot arm to pick up the material is formed between the material picking station 11 and the first guide plate 12. When the first lifting plate 31 and the second lifting plate 32 rise to the designated height, the slope surface of the first lifting plate 31 contacts the slope surface of the second guide plate 13, and the blank on the first lifting plate 31 is transferred to the second guide plate 13; at the same time, the slope surface of the second lifting plate 32 contacts the slope surface of the first guide plate 12, and the blank on the second lifting plate 32 is transferred to the first guide plate 12; finally, the blank is transferred to the material picking station 11, waiting for the robot arm to grab it; When the first lifting plate 31 and the second lifting plate 32 are reset, the slope of the second lifting plate 32 falls back and connects with the slope of the second guide plate 13; at the same time, the first lifting plate 31 falls back to a height lower than the front section 41 of the frame, so that the blank on the sliding frame 4 is transferred to the first lifting plate 31; this cycle operation can realize the step-type feeding operation of the shaft blank.

[0037] Please see Figure 12The replenishment box 61 has a lifting guide groove 64 that is adapted to slide with the sealing plate 62 on one side near the material picking station 11, and the bottom wall of the replenishment box 61 is sloping. Among them, the lifting guide groove 64 can improve the accuracy of the sliding direction of the sealing plate 62; The bottom wall of the feeding box 61 is sloped to facilitate the discharge of the blank from the feeding port 63.

[0038] Please see Figure 10 and Figure 11 The transmission mechanism 7 includes a trigger plate 72 that is slidably connected to the baffle 2. A connecting frame 71 is fixed between the trigger plate 72 and the sealing plate 62. An elastic member 73 for elastically supporting the trigger plate 72 is fixed inside the baffle 2. Among them, since the trigger plate 72 and the elastic element 73 cooperate to form an elastic support structure for the sliding frame 4, the elastic support structure can play a collision buffering role for the shaft blank falling from the feeding port 63.

[0039] Please see Figure 11 The elastic element 73 includes a spring sleeve 731 fixed inside the baffle 2. A telescopic slide column 732 is slidably connected inside the spring sleeve 731. A lifting ring plate 733 and a return spring 734 are sleeved on the part of the telescopic slide column 732 that extends into the spring sleeve 731. The lifting ring plate 733 is fixed on the telescopic slide column 732. One end of the return spring 734 is fixed on the end face of the lifting ring plate 733, and the other end of the return spring 734 is fixed on the bottom wall of the spring sleeve 731. The two ends of the return spring 734 are fixed between the lifting ring plate 733 and the inner bottom wall of the spring sleeve 731, respectively, so that the telescopic slide 732 can extend and retract inside the spring sleeve 731 to ensure that the trigger plate 72 has a good elastic buffering effect. When the remaining material in the front section of the hopper is emptied, the elastic deformation of the return spring 734 is restored, the trigger plate 72 rises and resets, and the front section 41 of the lifting frame reaches the height of point C (reference). Figure 6 When there is sufficient raw material remaining in the rear section of the silo, the front section 41 of the frame reaches the height of point A (reference). Figure 4 The return spring 734 is compressed and deformed; when the remaining material in the rear section of the hopper is emptied, the front section 41 of the frame reaches the height of point B (reference). Figure 5 When the trigger plate 72 reaches its lowest point, the return spring 734 is subjected to maximum compression deformation.

[0040] Please see Figure 10The warning mechanism 8 includes a first warning unit 81 and a second warning unit 82. The first warning unit 81 is fixed on a baffle 2, and the second warning unit 82 is fixed on another baffle 2. A striking ball 83 is fixed on the trigger plate 72. The first warning unit 81 includes a first sound box 811 fixed on a baffle 2. A first sound bell 812 for striking the ball 83 to produce sound is fixed inside the first sound box 811. The second warning unit 82 includes a second sound box 821 fixed on another baffle 2. A second sound bell 822 for striking the ball 83 to produce sound is fixed inside the second sound box 821. The second sounding bell 822 is set at a higher height than the first sounding bell 812. The first sounding bell 812 is set to a low-pitched warning sound, while the second sounding bell 822 is set to a high-pitched warning sound. When there is sufficient raw material remaining in the rear section of the silo, the front section 41 of the frame reaches the height of point A (reference). Figure 4 No alarm sound was triggered; when the remaining material in the rear section of the hopper was emptied, the front section 41 of the frame reached the height of point B (reference). Figure 5 ), striking ball 83 strikes the first sounding bell 812, triggering a low warning sound; when the remaining material in the front section of the hopper is emptied, the front section 41 of the lifting frame reaches the height of point C (reference). Figure 6 ), striking the ball 83 strikes the second sounding bell 822, triggering a sharp warning sound; On-site staff can distinguish different warning sounds by hearing, which allows them to quickly and easily understand the remaining quantity and distribution of materials in the silo without visual inspection. This improves the shortcomings of the narrow and long silo structure, which can easily obstruct the staff's view and reduces the trouble caused by unclear visual observation leading to unclear understanding of the remaining quantity and distribution of materials in the silo.

[0041] Please see Figure 1 , Figure 7 and Figure 9 The loading workbench 1 is fixed with a guide rail 15. The lower ends of the opposite sides of the two baffles 2 are fixed with sliding plates 14 that are adapted to slide with the guide rail 15.
