Description

Technical Field

[0001] This application relates to the field of goods storage equipment technology, and in particular to a fully hydraulically driven cone-bottom unloading machine with automatically adjustable self-flow rate. Background Technology

[0002] Conical-bottom silos are commonly used storage devices in the grain, oil, food, and feed industries, possessing unique advantages. They consist of a silo body, a cone-shaped structure, and a discharge port, forming a complete material storage and discharge system. In daily operation, after opening the discharge port, the material should flow out naturally under gravity.

[0003] However, due to their inherent characteristics, such as irregular shape, large density differences, and varying particle surface areas and friction coefficients, materials often form a large angle of repose when accumulating in a silo. This makes it difficult for even the most rationally designed conical section of a cone-bottom silo to completely rely on gravity to smoothly discharge all the material. Increasing the height of the silo's conical section can increase the cone angle. While this method can improve the gravity flow of materials to some extent, increasing the height of the silo's conical section undoubtedly increases construction costs. Furthermore, an excessively high cone also increases the instability of the silo, posing a certain threat to its safety performance.

[0004] More complexly, the quality of organic materials such as grains, oils, and feed is highly susceptible to environmental factors during storage. Changes in temperature and fluctuations in humidity can cause qualitative changes in the materials. After prolonged storage, materials may caking, with originally loose particles forming hard lumps due to mutual compression and adhesion. This not only affects the quality and nutritional value of the materials but also makes the unloading process extremely difficult. When caking materials are unloaded, the friction and compression between them intensify, easily leading to arching and bridging phenomena—that is, the materials form bridge-like structures within the storage facility, severely hindering normal material flow. This not only affects production efficiency but can also cause storage blockages, resulting in significant economic losses for the enterprise.

[0005] Therefore, in addition to relying on gravity for material discharge, auxiliary equipment or methods are generally installed or adopted to assist material discharge. Examples include vibration discharge, which uses a vibrating device installed on the outside of a steel cone bottom to assist material discharge; percussion discharge, which uses a striking device installed on the outside of a steel cone bottom to assist material discharge; and airflow discharge, which uses openings and compressed air inlets around the bottom circumference of the cone bottom.

[0006] Traditional methods of discharging materials from the silo, relying on gravity flow and auxiliary devices, are not ideal for breaking up arches and caking, especially for cleaning residual and caking material at the bottom of the cone silo. Furthermore, prolonged vibration and impact on the silo bottom pose a risk of damage. The gravity flow rate is uncontrollable; with traditional methods, the flow rate is only related to the pre-designed discharge flange at the bottom of the cone silo, and once designed, it cannot be changed or adjusted in real-time. If there is a need to change the material inside the silo, the pre-designed discharge flange may not be able to meet the production requirements due to the different gravity flow characteristics of different materials. When downstream equipment or production needs require a small output, the gravity flow characteristics of the material may not be sufficient to meet the demand, resulting in a high minimum output limit for the discharging machine. Summary of the Invention

[0007] In order to improve the efficiency of the fully hydraulically driven cone-bottom discharge machine with automatic self-flow adjustment during use, this application provides a fully hydraulically driven cone-bottom discharge machine with automatic self-flow adjustment.

[0008] This application provides a fully hydraulically driven cone-bottom discharge machine with automatically adjustable self-flow rate, employing the following technical solution: A fully hydraulically driven, self-flowing, automatically adjustable cone-bottom discharge machine includes a silo with a cone-shaped bottom. A first flange mounting plate is installed at the bottom end of the cone-shaped bottom, and a discharge assembly is connected to the center of the cone-shaped bottom. The discharge assembly includes a fixed part connected to the first flange mounting plate, a rotating part connected to the fixed part, and an auger for stirring the material installed on the rotating part.

[0009] By adopting the above technical solution, the discharge component is installed at the center of the conical bin bottom. The auger can agitate the material, break up material caking and arching, and at the same time help the material flow, improve discharge efficiency, and solve the problem of unsmooth material discharge in the traditional bin discharge method.

[0010] In one specific implementation, the fixing part includes a fixing plate connected to the first flange mounting plate. A revolution gear is rotatably mounted on the fixing plate, and a revolution reducer for controlling the rotation of the revolution gear is mounted on the fixing plate. A revolution hydraulic motor is connected to the revolution reducer, and a slewing support is connected to the upper part of the fixing plate. The fixing plate is connected to the outer ring of the slewing support.

[0011] By adopting the above technical solution, the orbital hydraulic motor provides power, which is reduced by the orbital reducer and drives the orbital gear to rotate, providing the power basis for the orbital motion of the rotating part. The rotational support provides stable support for the rotation of the rotating part, ensuring the smoothness of the orbital process.

[0012] In one specific implementation scheme, the rotating part includes a rotating cylinder connected to the inner ring of the rotating support. A bearing housing is mounted on the rotating cylinder, and a self-rotating reducer is connected to the bearing housing. A self-rotating hydraulic motor providing a power source is connected to the self-rotating reducer, and the auger is connected to the bearing housing. A large gear is mounted on the rotating cylinder, and a chain meshes with the large gear and the revolution gear.

[0013] By adopting the above technical solution, the orbital gear drives the large gear disc to rotate through the chain, which in turn drives the rotary cylinder to revolve around the central axis of the silo. At the same time, the self-rotating hydraulic motor drives the auger to rotate through the self-rotating reducer, realizing the compound motion of the auger's orbital rotation and self-rotation, expanding the material agitation range, and improving the arch breaking and conveying effect.

[0014] In one specific implementation scheme, a bushing is installed on the rotary drum, and a material gate is slidably installed on the rotary drum through the bushing. The material gate has an oblong hole, and the bushing passes through the oblong hole. A telescopic cylinder is installed on the rotary drum, and the output shaft of the telescopic cylinder is connected to a connecting rod. A sliding groove is provided on the rotary drum, and the connecting rod passes through the sliding groove and connects to the material gate.

[0015] By adopting the above technical solution, the telescopic cylinder drives the connecting rod to move along the slide groove, which in turn drives the material gate to slide along the bushing. By adjusting the opening of the material gate, the flow rate can be adjusted in real time to meet the needs of different materials and different outputs.

[0016] In one specific implementation scheme, a hydraulic rotary distributor is connected to the end of the rotary cylinder away from the fixed part. The end of the hydraulic rotary distributor near the rotary cylinder can rotate with the rotary cylinder. A second flange mounting plate is connected to the end of the hydraulic rotary distributor away from the rotary cylinder. A torque arm connecting rod is connected to the hydraulic rotary distributor, and a fixing rod for fixing the torque arm connecting rod is connected to the torque arm connecting rod.

[0017] By adopting the above technical solution, the hydraulic rotary distributor achieves stable hydraulic oil delivery during rotation, ensuring that hydraulic components such as the self-rotating hydraulic motor and telescopic cylinder work normally during rotation. The torque arm connecting rod and the fixing rod fix the lower part of the hydraulic rotary distributor to prevent it from rotating with the rotating cylinder.

[0018] In one specific implementation, a flexible connector, which is a rubber hose, is connected between the hydraulic rotary distributor and the second flange mounting plate.

[0019] By adopting the above technical solutions, the rubber hose has good flexibility, which can absorb vibration and deviation during installation and operation, avoid component damage caused by rigid connection, and facilitate installation and debugging.

[0020] In one specific implementation, a displacement sensor for detecting the displacement of the connecting rod is installed on the rotary cylinder.

[0021] By adopting the above technical solution, the displacement sensor detects the displacement of the connecting rod in real time, thereby accurately feeding back the opening size of the material gate and providing data support for the precise adjustment of the flow rate.

[0022] In one specific implementation scheme, a material level sensor is installed on the rotary drum, the head of which extends into the interior of the rotary drum to sense changes in material level. A wireless transmission module is installed on the rotary drum, and the displacement sensor and the material level sensor are communicatively connected to the wireless transmission module. The wireless transmission module is communicatively connected to a hydraulic pump station and an electrical cabinet, and the electrical cabinet is controlled by a PLC to form an electrical control system.

[0023] By adopting the above technical solution, when the discharge machine is working, the material level sensor monitors the material level in the cylinder in real time. When a blockage is detected, a signal is sent to the electrical control system through the wireless transmission module. The PLC controls the telescopic cylinder to adjust the opening of the material gate, thereby realizing automatic adjustment of the flow rate without manual intervention, which improves the automation level and operational stability of the equipment.

[0024] In one specific implementation, the auger is welded with helical blades, and toothed blades are mounted on the helical blades.

[0025] By adopting the above technical solutions, the spiral blades enhance the material conveying capacity, and the toothed blades can effectively break up hardened material blocks, further improving the arch breaking and clearing effect and reducing material residue at the bottom of the silo.

[0026] In one specific implementation, the hydraulic pump station is connected to a solenoid valve, and the PLC control system is communicatively connected to the solenoid valve. The PLC control system controls the extension and retraction of the telescopic cylinder by controlling the solenoid valve.

[0027] By adopting the above technical solution, the output signal of the scraper conveyor is transmitted to the PLC. The PLC determines the relationship between this output and the set output of the discharge machine. If the current output is greater than the set output, the PLC sends a control signal to the solenoid valve, which controls the telescopic cylinder to retract. If the current output is less than the set output, the PLC sends a control signal to the solenoid valve, which controls the telescopic cylinder to extend. This negative feedback closed-loop control continues until the current output equals the set output. Then, the PLC sends a control signal to the solenoid valve, which controls the telescopic cylinder to stop moving. This output control strategy can reduce the lower limit of the cone bottom discharge machine's output by controlling the gravity flow, thus meeting the downstream output demand.

[0028] In one specific implementation scheme, a material feeding assembly is installed on the rotary cylinder. The material feeding assembly includes a fixed shaft seat mounted on the rotary cylinder. A rotating seat is rotatably mounted on the fixed shaft seat. A material feeding mesh plate is hinged to the rotating seat. A rotating block is mounted on the material feeding mesh plate. The rotating block is coaxial with the rotating seat and has a spherical surface. A support rod is slidably mounted on the fixed shaft seat. One end of the support rod near the rotating block abuts against the spherical surface on the rotating block. A first rotary motor for controlling the movement of the support rod is installed on the rotary cylinder. A connecting plate is mounted on the rotating cylinder. A pull rod is hinged to the connecting plate. A second push plate is hinged to the pull rod. A second rotary motor for controlling the movement of the second push plate is installed on the rotary cylinder.

[0029] By adopting the above technical solution, after the material falls from the material gate on the rotary drum, it first lands on the material-dispersing screen plate. The screen plate can further disperse the material, preventing it from clumping and affecting subsequent conveying. When it is necessary to adjust the material's falling position, the first rotary motor controls the first screw to rotate, driving the first push plate to move the support rod. The support rod, through the spherical surface of the rotating block, pushes the material-dispersing screen plate to rotate around the hinge point, realizing the adjustment of the screen plate's tilt angle in one direction, thereby guiding the material flow. At the same time, the second rotary motor controls the second screw to rotate, driving the second push plate to pull the pull rod. The pull rod, through the connecting plate, drives the rotating seat to rotate, causing the material-dispersing screen plate to rotate and tilt in the axial direction of the rotating seat, realizing the adjustment of the falling direction in the other direction. Through bidirectional adjustment, the material's falling position can be flexibly controlled, preventing the downstream conveyor belt from shifting due to excessive material falling on one side, and preventing material accumulation from forming mounds that affect the monitoring accuracy of the material level sensor, further improving the stability and reliability of the equipment operation.

[0030] In summary, this application includes at least one of the following beneficial technical effects: 1. The rotation and revolution of the spiral auger enable the central forced conveying and effective arch breaking of all materials in the bin; it is fully hydraulically driven, with a simple structure that does not require electric slip rings. The hydraulic pump station can use a common fixed-frequency motor, and the rotation speed of the auger can be achieved through the hydraulic system. Even when the auger is blocked and difficult to start, the motor can still start under light load. The hydraulic system can continuously provide high torque, which can effectively deal with the problem of starting some special materials. 2. By using a telescopic hydraulic cylinder to drive the opening and closing of the material gate, combined with feedback from displacement sensors and material level sensors, real-time adjustment and automatic control of the flow rate can be achieved to meet the needs of different materials and different outputs, and reduce the minimum output limit of the warehouse.

Detailed Implementation

[0042] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0043] This application discloses a fully hydraulically driven cone-bottom discharge machine with automatically adjustable self-flow rate, referring to... Figure 1 and Figure 2 It includes a silo 1, the bottom of which is a conical silo bottom 11. A first flange mounting plate 21 is fixedly connected to the bottom of the conical silo bottom 11, and a discharge assembly 2 is fixedly installed at the center of the conical silo bottom 11 through the first flange mounting plate 21.

[0044] Reference Figure 2 and Figure 3 The discharge assembly 2 includes a fixing part 22 fixedly connected to the conical bin bottom 11. The fixing part 22 includes a fixing plate 221. The fixing plate 221 is fastened to the first flange mounting plate 21 by bolts. A rotating planetary gear 222 rotates on the fixing plate 221. A planetary reducer 223 that controls the rotation of the planetary gear 222 is fixedly installed on the fixing plate 221. A planetary hydraulic motor 224 that provides a power source is connected to the planetary reducer 223. A slewing support 225 is fixedly connected to the bottom surface of the fixing plate 221 by bolts. The fixing plate 221 is connected to the outer ring of the slewing support 225.

[0045] The inner ring of the slewing support 225 is connected to a rotating part 23, which includes a rotating cylinder 231. The rotating cylinder 231 is fixedly connected to the inner ring of the slewing support 225 by bolts. A bearing housing 232 is fixedly mounted on the rotating cylinder 231. A self-rotating reducer 233 is fixedly connected to the bearing housing 232. A self-rotating hydraulic motor 234, which provides a power source, is fixedly connected to the self-rotating reducer 233. An auger 235 is connected to the bearing housing 232. Spiral blades 2351 are welded to the auger 235, and toothed blades 2352 are fixedly mounted on the spiral blades 2351.

[0046] Reference Figure 4 , Figure 5 and Figure 6 A bushing 241 is fixedly installed on the top surface of the rotary drum 231. A material gate 242 is slidably installed on the rotary drum 231 through the bushing 241. The material gate 242 has an oblong hole 2421, through which the bushing 241 passes. A telescopic cylinder 243 is fixedly installed on the rotary drum 231. A connecting rod 244 is fixedly connected to the output shaft of the telescopic cylinder 243. A sliding groove 2311 is provided on the rotary drum 231, through which the connecting rod 244 passes and is fixedly connected to the material gate 242. A displacement sensor 245 is fixedly installed on the rotary drum 231 to detect the displacement of the connecting rod 244.

[0047] Reference Figure 2 and Figure 7A large gear 251 is fixedly mounted on the rotating drum 231, and a chain 226 meshes with the large gear 251 and the planetary gear 222. A hydraulic rotary distributor 3 is fixedly connected to the bottom of the rotating drum 231 by bolts. A flexible connector 4 is fixedly connected to the end of the hydraulic rotary distributor 3 away from the rotating drum 231. The flexible connector 4 is a rubber hose, and a second flange mounting plate 5 is fixedly connected to the flexible connector 4. The second flange mounting plate 5 is used to connect with the scraper conveyor that receives materials. In this embodiment, the hydraulic rotary distributor 3 is prior art. The upper part of the hydraulic rotary distributor 3 can rotate with the rotating part 23, and the lower part of the hydraulic rotary distributor 3 is fixedly connected to a torque arm connecting rod 31. A fixing rod 32 is fixedly connected to the torque arm connecting rod 31 and is fixedly mounted on the second flange mounting plate 5.

[0048] Hydraulic oil flows into the self-rotating hydraulic motor 234 through the upper part of the hydraulic rotary distributor 3, driving the self-rotating hydraulic motor 234 to rotate. The self-rotating hydraulic motor 234 drives the self-rotating reducer 233 to drive the auger 235 to rotate via the bearing box 232. The rotation of the auger 235 realizes the conveying of materials to the center of the bottom of the bin and the breaking of arches.

[0049] The revolution hydraulic motor 224 drives the revolution reducer 223 to operate, which in turn drives the revolution gear 222 installed on the revolution reducer 223 to move. The revolution gear 222 is connected to the large gear disc 251 through the chain 226. The rotation of the revolution gear 222 drives the large gear disc 251 to rotate. The large gear disc 251 is connected to the rotating cylinder 231, which drives the entire rotating cylinder 231 to rotate around the central axis of the silo 1, thereby realizing the revolution motion of the spiral auger 235.

[0050] After being distributed by the hydraulic rotary distributor 3, the hydraulic oil flows into the telescopic cylinder 243, which drives the material gate 242 to open and close, thereby controlling the size of the discharge port.

[0051] Reference Figure 1 , Figure 2 and Figure 3 A material level sensor 61 is fixedly installed on the rotating drum 231, with its head extending into the interior of the drum 231 to sense changes in material level. A wireless transmission module 62 is fixedly installed on the rotating drum 231. A displacement sensor 245, which senses the extension displacement of the telescopic cylinder 243, and the material level sensor 61, which senses the material level inside the rotating drum 231, are communicatively connected to the wireless transmission module 62. In this embodiment, a hydraulic pump station and an electrical cabinet providing a power source are provided beside the silo 1. A solenoid valve is connected to the hydraulic pump station, and the electrical cabinet is controlled by a PLC to form an electrical control system that is communicatively connected to the wireless transmission module 62, the hydraulic pump station, and the solenoid valve. PLC control is existing technology and does not affect the understanding of this solution; therefore, the PLC control program is not described in this embodiment.

[0052] The material level sensor 61 detects the material level height inside the rotary drum 231 and sends it to the electrical control system via the wireless transmission module 62. The PLC determines whether the material blockage threshold has been reached. If the threshold is reached, a command is sent to the solenoid valve to control the extension cylinder 243 to extend. The extension cylinder 243 moves the material gate 242 towards the center, reducing the opening of the material gate 242 and thus reducing the gravity flow, thereby reducing the output of the discharge machine. The material level sensor 61 continuously detects the material level height and sends the data to the control system. When the PLC detects that the material level signal sent by the material level sensor 61 this time is lower than the previous material level signal, it sends a command to control the extension cylinder 243 to stop extending. The material in the rotary drum 231 gradually decreases. This output control strategy can reduce the lower limit of the cone bottom discharge machine's output by controlling the gravity flow, which can meet the small output needs of downstream applications.

[0053] Reference Figure 8 , Figure 9 and Figure 10 A material feeding assembly 7 is installed on the rotary drum 231, positioned above the material level sensor 61. The material feeding assembly 7 includes a fixed shaft seat 71, which is fixedly mounted on the rotary drum 231. A rotating seat 72 is rotatably mounted on the fixed shaft seat 71. A seat ear 721 is fixedly mounted on the rotating seat 72, and a material feeding mesh plate 73 is hinged to the seat ear 721. A rotating block 74 is fixedly mounted on the material feeding mesh plate 73, coaxial with the rotating seat 72, and having a spherical surface 741. A support rod 75 is slidably mounted on the fixed shaft seat 71, with one end of the support rod 75 near the rotating block 74 abutting against the spherical surface 741 on the rotating block 74. The end of the support rod 75 abutting against the rotating block 74 has an arc-shaped surface. A first mounting box 761 is fixedly installed on the outer wall of the rotary cylinder 231. A first screw 762 is rotatably installed on the first mounting box 761. A first rotary motor 763 that controls the rotation of the first screw 762 is fixedly installed on the first mounting box 761. A first push plate 764 is threadedly connected to the first screw 762. The first push plate 764 is fixedly connected to the support rod 75.

[0054] A second mounting box 771 is fixedly installed on the rotary cylinder 231. A second screw 772 is rotatably installed on the second mounting box 771. A second rotary motor 773 that controls the rotation of the second screw 772 is fixedly installed on the second mounting box 771. A second push plate 774 is threadedly connected to the second screw 772. A pull rod 775 is hinged to the second push plate 774. A connecting plate 776 is fixedly installed on the rotating seat 72. The end of the pull rod 775 away from the second push plate 774 is hinged to the connecting plate 776.

[0055] After the material falls from the material gate 242 on the rotary drum 231, it lands on the material-dispersing mesh plate 73, which then disperses the material again. When it is necessary to adjust the position of the falling material, it can be understood that the downstream of the discharge machine is a conveyor belt that receives the material. Adjusting the position of the material on the conveyor belt prevents the conveyor belt from shifting due to excessive material falling on one side. It can also be understood that when the material discharge is large, it prevents the material from accumulating and forming a mound, which would affect the monitoring effect of the material level sensor 61. At this time, the first rotary motor 763 controls the first screw 762 to rotate, the first screw 762 controls the first push plate 764 to move, the first push plate 764 pushes the support rod 75 to move, and the support rod 75 pushes the rotating block 74. Through the action of the spherical surface 741 on the rotating block 74, the support rod 75 pushes the material-dispersing mesh plate 73 to rotate upward and tilt, thereby guiding the flow of the material. At the same time, the second rotary motor 773 controls the second screw 772 to rotate, the second screw 772 controls the second push plate 774 to move, the second push plate 774 drives the pull rod 775 to move, and the pull rod 775 pushes and pulls the rotating seat 72 to make the rotating seat 72 rotate, thereby causing the feeding screen plate 73 to rotate and tilt in the axial direction of the rotating seat 72, guiding the direction of material falling.

[0056] The implementation principle of this application embodiment is as follows: When the equipment is working, the hydraulic pump station provides hydraulic power, and the hydraulic oil is delivered to the revolution hydraulic motor 224, the self-rotation hydraulic motor 234 and the telescopic cylinder 243 respectively through the hydraulic rotary distributor 3. The revolution hydraulic motor 224 drives the revolution gear 222 to rotate through the revolution reducer 223, and drives the large gear disk 251 and the rotating cylinder 231 to revolve around the central axis of the silo 1 through the chain 226; the self-rotation hydraulic motor 234 drives the auger 235 to rotate through the self-rotation reducer 233, the spiral blades 2351 push the material to move towards the discharge port, and the toothed blades 2352 break up the caking material to achieve arch breaking and material conveying.

[0057] The telescopic cylinder 243 drives the material gate 242 to slide according to PLC instructions, adjusting the opening of the discharge port. The displacement sensor 245 provides feedback on the position of the material gate 242, ensuring precise control of the opening. The material level sensor 61 monitors the material level in real time. When material blockage occurs, the PLC controls the material gate 242 to reduce its opening. After the material level drops, the opening is restored, achieving automatic flow regulation. The hydraulic rotary distributor 3 ensures a stable supply of hydraulic oil during rotation, and the flexible connector 4 absorbs vibration, improving the stability of equipment operation.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
