Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flow scales, in particular to a digital intelligent flow scale. BACKGROUND

[0002] As a core equipment for dynamic measurement of bulk grain in agricultural product technology, especially the impact flow scale, its working principle relies on the mechanical response generated by the continuous impact of the material on the detection plate. In ideal working conditions, the grain impacts the inclined plate at a constant flow rate, and the vertical and horizontal components are measured to calculate the flow rate using a flow integrator.

[0003] In the prior art, especially when handling large-particle materials such as corn, lentils, and chickpeas, the conveying pipeline under high flow conditions is prone to form a dynamic deceleration and retention area for the grain after the vertical detection plate, i.e., after the grain changes the conveying path by impacting the detection plate twice and enters the bottom of the chute, which easily causes accumulation and blockage, thereby disrupting the continuity of grain flow and making it impossible to accurately calculate the flow rate.

[0004] The existing solution is to install a vibrator, but this type of solution cannot timely detect blockage and, if used for a long time, will cause structural fatigue, making it impossible to effectively measure and detect, and thus cannot guarantee the efficiency and accuracy of the equipment.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Reference Figures 1-5 A digital intelligent flow scale includes a housing 1, the inner cavity of which is divided into an upper detection area 101 and a lower conveying area 102; A horizontal impact plate 2 is vertically installed on one side of the inner side of the detection area 101. One side of the horizontal impact plate 2 is spliced ​​with the vertical impact plate 3 to form a pipeline structure for conveying materials. The outer middle of both the vertical impact plate 3 and the horizontal impact plate 2 is connected to a sensor 5, which is installed on the outside of the housing 1.

[0021] The end outlet of the pipe structure formed by splicing the horizontal impact plate 2 and the vertical impact plate 3 is connected to the conveying pipe 4. The conveying pipe 4 is located in the conveying area 102, and the bottom of the conveying pipe 4 extends outward to form a discharge port.

[0022] The outer side of the conveying pipe 4 is connected to a branch pipe 41. The bottom of the branch pipe 41 extends outward from the shell 1 to form a secondary discharge port. An electric tilting plate 6 is installed inside the branch pipe 41. When the electric tilting plate 6 is rotated and opened, the branch pipe 41 is connected to the conveying pipe 4.

[0023] In addition, a guide plate 103 is provided on the upper side away from the horizontal impact plate 2, and the guide plate 103 is inclined towards the horizontal impact plate 2.

[0024] It should be noted that sensor 5, specifically the MT1260 single-point stress sensor, has its sensing end connected to the horizontal impact plate 2 and the vertical impact plate 3. It converts the force generated by the material impacting the horizontal impact plate 2 and the vertical impact plate 3 into an electrical signal, which is then transmitted to the external processing mechanism through the signal output port to achieve flow monitoring in conjunction with the flow totalizer.

[0025] In addition, a feed inlet is provided at the top of the housing 1.

[0026] Reference Figures 5-12 A support shaft 111 is rotatably mounted on the upper part of the conveying pipe 4 via a bearing seat. A pair of vibrating rods 10 are rotatably mounted on the middle part of the support shaft 111 via a bearing. One end of each vibrating rod 10 passes through the movable groove 42 opened on the upper part of the conveying pipe 4 and extends into the interior of the conveying pipe 4 and is inserted into the limiting rod 12.

[0027] Multiple sets of excitation rods 11 are symmetrically fixed on both sides away from the vibrating rod 10. In a natural state, the excitation rods 11 naturally hang vertically under their own weight. In addition, each excitation rod 11 is provided with a finger block 112 at its upper part. The finger block 112 extends upward and presses against the inner wall of the arc-shaped starter plate 8. The arc-shaped starter plate 8 is rotatably mounted on one side of the upper wall of the delivery pipe 4 via a pin shaft. One end of the pin shaft is connected to a synchronization plate 81. A locking pin 82 is rotatably mounted in the middle of the synchronization plate 81 via a pin shaft.

[0028] Furthermore, an excitation rocker arm 100 is rotatably connected to one end of each vibrating rod 10. A limiting groove 1001 is opened in the middle of the excitation rocker arm 100 and a connecting rod 91 is limited and connected. The connecting rod 91 is installed in the middle of the crankshaft 9. The crankshaft 9 is rotatably installed on one side of the outer wall of the conveying pipe 4. One end of the crankshaft 9 extends into the equipment box 7 and is driven and connected to the motor component 13. Specifically, the upper wall of the conveying pipe 4 is provided with multiple movable grooves 42, and the movable grooves 42 are respectively configured with vibration rods 10 and excitation rods 11. The movable grooves 42 are used to meet the rotation requirements of the excitation rods 11.

[0029] Specifically, the motor component 13 is installed inside the equipment box 7 on one side, and the drive end is driven to connect with the crankshaft 9. Multiple connecting rods 91 are rotatably installed in the middle of the crankshaft 9. A pin is provided in the middle of the connecting rod 91, and the pin is inserted into the limiting groove 1001 opened in the middle of the excitation rocker arm 100.

[0030] Reference Figures 12-16 One end of the support shaft 111 extends into the pump body 18 inside the equipment box 7 and is connected to a ratchet disc 113. The ratchet disc 113 is coaxially installed inside the pawl disc 19. The pawl disc 19 and the ratchet disc 113 are rotatably connected by a shaft. The pawl disc 19 has a concave structure and multiple pawls 193 are rotatably installed on the inner wall of the pawl disc 19 via pins. Each pawl 193 is engaged and locked with the outer tooth groove of the ratchet disc 113.

[0031] It should be noted that a torsion spring is installed at the rotatable connection between the pawl 193 and the pawl disc 19 to assist the pawl 193 in resetting. This is a conventional setting of ratchet and pawl mechanisms and is common knowledge to those skilled in the art, so it will not be explained further.

[0032] Next, a drive cylinder 191 is coaxially mounted on one side of the ratchet disk 19. The drive cylinder 191 rotates synchronously with the ratchet disk 19, and several limiting slots 192 are formed in a ring array on the outer wall of the drive cylinder 191. In the natural state, the limiting slots 192 engage with the locking pins 82.

[0033] The drive cylinder 191 and the ratchet disc 19 are assembled together inside the pump body 18. A three-way cylinder 15 is installed at the bottom of the pump body 18. A plunger 153 is installed in the vertical chamber of the cylinder. The upper end of the plunger 153 is rotatably connected to the eccentric journal of the drive cylinder 191 through the drive connecting rod 154, which converts the rotational motion of the drive cylinder 191 into the linear reciprocating motion of the plunger 153.

[0034] An oil tank 14 is connected to the horizontal end of one side of the cylinder body 15. The oil tank 14 is filled with hydraulic oil. An oil suction valve ball 151 is provided at the connection between the oil tank 14 and the cylinder body 15. A sealing element is provided on the contact surface between the oil suction valve ball 151 and the cylinder body 15. One side of the oil suction valve ball 151 is connected to the cylinder body 15 through a spring element to suction oil and reset.

[0035] Conversely, an oil drain valve ball 152 is provided on the other side of the cylinder body 15. The contact surface between the oil drain valve ball 152 and the cylinder body 15 is provided with a sealing element, and one side of the oil drain valve ball 152 is connected to the cylinder body 15 through a spring element to drain oil and reset. Reference Figure 16 , Figure 19 An excitation cylinder 20 is installed on one side of the cylinder body 15, and a pressure relief valve 16 is installed on the side away from the excitation cylinder 20. The input end of the pressure relief valve 16 is connected to the inside of the cylinder body 15, and the output end is connected to the inside of the oil tank 14 through the return oil pipe 161.

[0036] Next, an I-shaped piston 21 is installed at the connection between the excitation cylinder 20 and the cylinder body 15. One end of the I-shaped piston 21 extends into the cylinder body 15 and is equipped with a sealing piston. The sealing piston is installed inside the cylinder body 15. A spring 22 is connected between the sealed piston and the inner wall of the cylinder 15 to realize the movement and reset function of the I-shaped piston 21.

[0037] The other end of the I-shaped piston 21 extends into the interior of the excitation cylinder 20 and is provided with a circular plate with the same inner diameter as the excitation cylinder 20. A magnetic plate 23 is installed in the middle of the circular plate. The top and bottom of the circular plate are provided with slots to fit the convex rail 24 provided on the inner wall of the cylinder 15. The convex rail 24 is used to restrict the I-shaped piston 21 to achieve horizontal linear movement.

[0038] Furthermore, an excitation plate 25 is installed on one side of the inner side of the excitation cylinder 20 via a spring 252. In its natural state, there is a gap between the excitation plate 25 and the I-shaped piston 21.

[0039] Among them, the excitation plate 25 is provided with a magnetic plate 253 in the middle. The magnetic plate 253 and the magnetic suction plate 23 provided in the middle of the I-shaped piston 21 constitute a magnetic suction mechanism. The excitation plate 25 is embedded with a horizontally extending copper contact plate 251. The two ends of the copper contact plate 251 symmetrically protrude from the outer wall of the excitation plate 25. The ends of the copper contact plate 251 are directly opposite the copper contact 241 provided on the outer wall of the convex rail 24. Each copper contact 241 is electrically connected to the motor component 13 and the electric flip plate 6 through a wire. When the excitation plate 25 is horizontally displaced, the copper contact plate 251 contacts the copper contact 241 of the convex rail 24 to form an electrical conduction circuit, thereby activating the motor component 13 and the electric tilting plate 6.

[0040] Reference Figure 10 , Figures 12-15One end of the arc-shaped starter plate 8 extends into the equipment box 7 and is connected to the synchronization plate 81. The middle part of the synchronization plate 81 is rotatably mounted with a locking pin 82 via a pin shaft. The bottom end of the locking pin 82 extends into the upper side of the pump body 18 and contacts the outer wall of the drive cylinder 191 configured inside the pump body 18. The outer wall of the drive cylinder 191 is provided with a limiting groove 192 to engage with the locking pin 82. Correspondingly, the bottom wall of the locking pin 82 is provided with a protrusion to engage with the limiting groove 192.

[0041] Reference Figure 17 A torsion spring 17 is installed at the rotatable connection of the support shaft 111. When the support shaft 111 rotates axially, the torsion spring 17 deforms to generate a torsional force to drive the support shaft 111 to reset and rotate.

[0042] Reference Figure 18 The limiting rod 12 is installed on the bottom wall of the conveying pipe 4 and inserted into the vibrating rod 10 with a gap between it and the inner wall of the vibrating rod 10 to meet the amplitude requirements of the vibrating rod 10.

[0043] In this embodiment, the grain enters the interior of the shell 1 through the feed inlet, and the guide plate 103 changes the material transmission direction, causing the material to come into contact with the horizontal impact plate 2 inside the shell 1. After colliding with the horizontal impact plate 2, the material changes the transmission direction again, causing it to fall into the vertical impact plate 3, and the vertical impact plate 3 continues to transport the material to the conveying pipe 4 until it is discharged.

[0044] During this process, the grain impact acts on the horizontal impact plate 2 and the vertical impact plate 3, generating horizontal and vertical impact force components in orthogonal directions, respectively. These impact force components are transmitted to the sensor 5 connected to one side of the impact plate (horizontal impact plate 2 and vertical impact plate 3), and the sensor 5 outputs an electrical signal to the external processing mechanism and the external flow totalizer to calculate and evaluate the grain flow rate.

[0045] Under low flow conditions, the grain tends to flow and be conveyed to the bottom side of the conveying pipe 4. The filling rate of the pipe cavity is low and significantly lower than the critical blockage threshold. The impact plate is under stable force and the sensor 5 can output the flow signal normally. Under high flow conditions, the grain accumulation layer rises to the top of the conveying pipe 4 or forms a full pipe flow. There may be brief intermittent blockages and there is a risk of complete blockage, which will cause the impact plate to be unable to bear force effectively, sensor 5 to fail, and the flow measurement accuracy cannot be guaranteed.

[0046] Under high flow conditions, grains (such as corn, beans, etc.) will collide with and contact multiple excitation rods 11 installed on the upper wall of the conveying pipe 4, causing each excitation rod 11 to be deflected by force and to present an inclined posture. At this time, the finger block 112 installed on the upper part of the excitation rod 11 rotates in the opposite direction and squeezes the inner wall of the arc-shaped starter plate 8 on one side. The horizontal displacement generated by the rotation of the finger block 112 will drive the arc-shaped starter plate 8 to deflect. Because grain is different from conventional fluids (such as air, oil, and water), grain particles cannot exert a continuous and stable force on the excitation rod 11. Therefore, during the actual conveying process, the grain will intermittently collide with the excitation rod 11, forcing the excitation rod 11 to oscillate periodically. Under the deformation and torsion of the torsion spring 17, it will generate continuous and repeated oscillations, which will drive the support shaft 111 connected to it to move synchronously.

[0047] Next, the rising grain accumulation layer causes the arc-shaped starter plate 8 to deflect. The arc-shaped starter plate 8 will synchronously drive the synchronous plate 81 located in the equipment box 7 to rotate synchronously. The synchronous plate 81 converts the rotational displacement into the vertical displacement of the locking pin 82 connected to it. At this time, the locking pin 82 will be driven to disengage from the drive cylinder 191 set inside the pump body 18, and the drive cylinder 191 can be unlocked to meet the corresponding rotation requirements.

[0048] At the same time, the support shaft 111 driven by the excitation rod 11 synchronously drives the ratchet disk 113 connected on one side to rotate periodically. The ratchet disk 113 moves inside the pawl disk 19 on one side of the drive cylinder 191 and engages with the pawl 193 inside the pawl disk 19. Under the periodic reciprocating action of the ratchet disk 113, it generates an intermittent driving force on the pawl disk 19, thereby driving the drive cylinder 191 to rotate intermittently and periodically.

[0049] In the ratchet-pawl mechanism formed by the pawl disc 19 and the ratchet disc 113, when the excitation rod 11 rotates due to the impact of the grain, it is in the locked direction. At this time, the ratchet disc 113 and the pawl 193 in the pawl disc 19 are engaged and constrained, and the pawl 193 and the tooth groove on the ratchet disc 113 engage to achieve torque transmission. Conversely, when the excitation rod 11 is reset and rotated by the torsion spring 17, it is in the active direction. The ratchet disc 113 moves freely relative to the pawl disc 19, and the pawl disc 19 does not produce displacement. This is consistent with the basic operating principle of the ratchet-pawl mechanism and will not be explained in detail.

[0050] Next, the drive cylinder 191 rotates continuously (one revolution) driven by the support shaft 111, and drives the piston 153 to reciprocate up and down in the cylinder 15 to perform pumping operation, thereby drawing the hydraulic oil in the oil tank 14 to the oil outlet on the other side of the cylinder 15. The I-shaped piston 21 located in the cylinder 15 moves outward under oil pressure. Under continuous pressure, when the oil pressure exceeds the set threshold of the pressure relief valve 16, the pressure relief valve 16 installed in the cylinder 15 will send the overpressurized oil back into the oil tank 14 through the return oil pipe 161, forming a closed-loop oil circuit circulation. The I-shaped piston 21, which is displaced by force, will continue to approach the excitation plate 25 until the magnetic plate 253 in the middle of the excitation plate 25 and the magnetic attracting plate 23 in the middle of the I-shaped piston 21 are magnetically attracted to each other. The two are magnetically attracted, and under the relatively stable oil pressure of the cylinder 15, the I-shaped piston 21 will always be in a locked state, that is, it will always be pressed tightly against the excitation plate 25.

[0051] Therefore, as long as the grain is continuously conveyed in the conveying pipe 4 under high flow conditions, the excitation rod 11 will swing frequently to synchronize the plunger 153 to continuously pump oil, and then the oil in the cylinder 15 will be in a relatively stable oil pressure state.

[0052] At this time, once the grain is blocked in the conveying pipe 4 for a long time (3-4 seconds) (i.e., blocked state), the plunger 153 will stop pumping oil and the pressure relief valve 16 will discharge the overpressure oil in time. Since there is no oil pressure force, the I-piston 21 will slowly reset under the action of the spring 22. Since the I-shaped piston 21 and the excitation plate 25 have completed the magnetic attraction docking operation, the excitation plate 25 will move outward synchronously in sync with the reset movement of the I-shaped piston 21 until the excitation plate 25 contacts the outer wall of the convex rail 24 used to limit the movement of the I-shaped piston 21 and prevents the excitation plate 25 from moving forward. At this time, the copper contact 251 on the excitation plate 25 will contact the copper contact 241 on the outer wall of the convex rail 24 to generate an electrical circuit and excite the motor component 13 to run. The copper contact piece 251 is connected to the motor component 13 and the electric flip plate 6 via wires. When the complete copper contact piece 251 is connected to the two copper contacts 241, the copper contacts 241 and the copper contact piece 251 form a connected circuit, allowing current to pass through.

[0053] At this time, the motor component 13 is excited and drives the crankshaft 9 to rotate. The connecting rod 2 91 converts the circular motion of the crankshaft 9 into vertical reciprocating motion. This reciprocating motion is linked to the excitation rocker arm 100 connected to the bottom of the connecting rod 2 91 to oscillate at high frequency around the support shaft 111, and drives the vibrating rod 10 to vibrate and directly impact the blocked material. Through the transmission of kinetic energy, the static friction structure of the material is destroyed, and vibration unblocking is achieved.

[0054] At the same time, the copper contact 241 synchronously triggers the drive circuit of the electric tilting plate 6 to perform a single rotation opening action, which lasts for 5 seconds to open the branch pipe 41 channel, so that the grain after vibration and clearing is partially discharged into the branch pipe 41 under the action of gravity, thus completing the auxiliary discharge. Correspondingly, when the I-shaped piston 21 is fully reset, the excitation plate 25, which is blocked by the convex rail 24, will magnetically disengage from the I-shaped piston 21 and reset under the action of the spring 252, and the copper contact plate 251 will disengage from the copper contact 241.

[0055] After the blockage is cleared, the material will resume continuous conveying, at which point plunger 153 will pump oil again.

[0056] It should be noted that sensor 5 generates an electrical signal based on the deformation of the impact plate under force, which is then processed by an external flow totalizer. The specific structure, operating principle, connection method, and acquisition, conversion, and calibration of the test data (evaluation standards) of sensor 5 and flow totalizer are common technical knowledge for those skilled in the art and will not be explained further.

[0057] Furthermore, the excitation and execution parameters (such as opening angle and duration) of the motor component 13 and the electric flip plate 6 can be determined by those skilled in the art through limited experiments based on actual production needs; the corresponding circuit excitation principle, control logic and related equipment are common knowledge to those skilled in the art and will not be explained further.

[0058] It is also worth noting that the plunger pump mechanism, which consists of cylinder block 15, suction valve ball 151, discharge valve ball 152, plunger 153, and drive connecting rod 154, conforms to the basic structure and operating principle of a plunger pump and will not be explained further. In this device, the suction valve ball 151 is installed in the connection channel between the cylinder body 15 and the oil tank 14. Under normal conditions, it is pressed against the valve seat seal by the spring preload, blocking the backflow of oil. When the plunger 153 moves upward, a negative pressure difference is formed in the cylinder body 15. The hydraulic oil pushes open the suction valve ball 151, overcomes the spring force and enters the cylinder cavity. The valve ball is separated from the valve cover, and the oil flows in one direction. The drain valve ball 152 is located on the drain side of the cylinder 15 (facing the excitation cylinder 20). Normally, it is pressed closed by the spring against the valve seat. When the plunger 153 moves down, the high-pressure oil pushes the drain valve ball 152 away from the valve seat sealing surface. The spring is compressed and stores energy, and the oil enters the other side of the cylinder 15. At the moment the plunger 153 returns, the spring releases energy and drives the drain valve ball 152 to close quickly, cutting off the reverse flow path.

[0059] The internal structure of the plunger pump not mentioned herein is a standard configuration and will not be explained further.

[0060] In addition, it should be noted that the electric tilting plate 5 includes a motor and a tilting plate. The tilting plate is rotatably installed in the middle of the branch pipe 41, and the rotation axis of the tilting plate is connected to the motor drive. The motor drives the tilting plate to rotate. This is a conventional configuration in the field and will not be explained further.

[0061] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
