Description

Technical Field

[0001] The invention belongs to the technical field of feed detection, and in particular relates to a device and method for detecting the quality of granular poultry feed. Background Art

[0002] Granular poultry feed is made by crushing and mixing feed raw materials (such as grains, beans, fish meal, bone meal, vitamins, minerals, etc.), and then pressing them into granular feeds of different diameters through special molds. Its production process usually includes steps such as raw material crushing, mixing, conditioning, granulation, cooling and screening. During the processing of conventional granular poultry feed, its quality often needs to be tested, and at this time, a quality testing device is required for testing.

[0003] The quality inspection of granular feed mainly detects whether its particle size meets the requirements. In the prior art, the feed particles to be tested are generally screened through two sieves of different sizes in turn. The common operation is to first pass through the sieve with a larger aperture and then through the sieve with a smaller aperture to keep the particle size in line with the requirements. However, the above operation process is relatively complicated and requires multiple transportation of the feed particles to be tested, resulting in low detection efficiency.

[0004] At the same time, when testing the quality of feed particles, qualified feed particles are generally discharged through the discharge port. However, due to the small particle size of the feed particles, some feed particles may remain on the discharge port. Although vibration is applied in the prior art to achieve the discharge of feed particles, some feed particles still need to be manually assisted in discharge, resulting in low discharge efficiency. Summary of the invention

[0005] The object of the present invention is to provide a device and method for detecting the quality of granular poultry feed to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical scheme: a granular poultry feed quality detection device, comprising a frame, an inner side surface of the frame is fixedly sleeved with a detection tank, a bottom end of the frame is fixedly installed with a vibration table, a right side of the detection tank is fixedly connected with a discharge box, a bottom end position of the discharge box near the right side is fixedly connected with a discharge port, a top end of the discharge box is fixedly installed with a power assembly, an auxiliary discharge assembly is arranged on the right side of the power assembly, the upper and lower ends of the detection tank are fixedly connected with waste ports, a fixed screen is connected to the inner cavity of the detection tank near the upper and lower ends by bolts, a movable screen is arranged at one end of the two fixed screens that are relatively close to each other, the number and size of apertures opened on the fixed screen and the movable screen are the same, a movable shaft is movably connected between the two movable screens, the movable shaft rotates relative to the two movable screens, a guide rod is fixedly sleeved on the outer side surface of the movable shaft near the bottom end, and the bottom end of the guide rod contacts the top end of the movable screen located below.

[0007] As a further technical solution of the present invention, telescopic rods are fixedly installed at the relatively distant ends of the two movable screens, and sealing plugs located on the outer side of the waste port are fixedly installed at the relatively distant ends of the two telescopic rods.

[0008] As a further technical solution of the present invention, one end of the telescopic rod close to the sealing plug passes through the middle of the fixed screen and is movably connected to the fixed screen. The movable screen rotates relative to the fixed screen. When the telescopic rod is in the initial state, the sealing plug is movably connected to the waste port and the waste port is sealed.

[0009] Before quality screening and testing, it is necessary to set a qualified particle size range according to quality requirements, and according to the particle size range, rotate the upper telescopic rod so that the upper telescopic rod and the movable screen rotate relative to the fixed screen, adjust the size of the overlapping screening holes of the upper fixed screen and the movable screen to ensure that it meets the maximum particle size requirements, and at the same time, according to the minimum particle size, rotate the lower telescopic rod to adjust the size of the overlapping screening holes of the lower fixed screen and the movable screen to ensure that it meets the minimum particle size requirements. After the adjustment is completed, it is necessary to pull the sealing plug upward so that the telescopic rod is elongated and drives the sealing plug to move upward. At this time, the upper waste port can be exposed, and the material can be poured into the inside of the detection tank through the upper waste port. At the same time, the vibration table is turned on to drive the detection tank to vibrate to complete the screening. At this time, the feed particles larger than the set particle size can stay at the top of the upper fixed screen, and the feed particles smaller than the set particle size can enter the bottom of the lower fixed screen and be respectively exported through the upper and lower waste ports, and the feed particles with qualified particle size can stay between the two movable screens to complete the quality inspection and screening process.

[0010] By setting up two sets of upper and lower fixed screens and movable screens, and adjusting the overlapping aperture sizes of the two sets of upper and lower fixed screens and movable screens respectively, the device only needs to pour the feed and cooperate with the vibration of the vibration table to quickly screen out oversized and undersized feed particles and quickly obtain qualified feed particles. The entire operation process is relatively simple and can be completed without multiple transfers, which effectively improves the detection efficiency.

[0011] As a further technical solution of the present invention, a first bevel gear is fixedly sleeved on the outer side surface of the movable shaft, and the right side of the first bevel gear is meshedly connected with a second bevel gear located inside the detection tank. The first bevel gear and the second bevel gear are perpendicular to each other, and a main shaft is fixedly sleeved on the middle part of the second bevel gear.

[0012] As a further technical solution of the present invention, the right side of the main shaft is located inside the discharge box and fixedly connected with the power component and connected to one side of the auxiliary discharge component. The power component includes a fixed seat, which is fixedly installed on the top of the discharge box.

[0013] As a further technical solution of the present invention, a motor is fixedly installed on the top of the fixed seat, a driving gear is fixedly installed on the output end of the motor, a driven gear is meshedly connected to the bottom end of the driving gear, and the middle part of the driven gear is fixedly sleeved with the main shaft.

[0014] When qualified feed particles stay between two movable screens after screening, the feed particles can be accumulated on the top of the movable screen below. At the same time, when screening, the motor can be turned on synchronously to drive the active gear to rotate. At this time, the driven gear below rotates accordingly, and the main shaft is driven to rotate at the same time. At this time, the second bevel gear on the left side of the main shaft rotates accordingly, and drives the first bevel gear in the meshing state to rotate, and finally drives the movable shaft to rotate relative to the two movable screens. At this time, the guide rod rotates circumferentially relative to the movable screen below and cleans the feed particles on the movable screen. As the screening proceeds, with the vibration, the qualified feed can be introduced into the inside of the discharge box in turn, and finally discharged through the discharge port, completing the active discharge process of qualified products.

[0015] By utilizing the vibration during screening and the coordination between the main shaft and the first bevel gear as well as the second bevel gear and the power assembly, the device can automatically export qualified feed particles during screening, thus avoiding the accumulation of feed particles and achieving rapid discharge of qualified feed. The entire process is completed quickly, further improving the overall screening and detection efficiency.

[0016] As a further technical solution of the present invention, the auxiliary discharge assembly includes a locking frame, the bottom end of the locking frame is connected to the discharge box, the inner side of the locking frame is fixedly sleeved with an air storage pipe, the air storage pipe is fixedly connected to the left position near the top of the air storage pipe with an air intake pipe, and the air storage pipe is fixedly connected to the right position near the top of the air storage pipe with an exhaust pipe, and one-way valves are installed inside the air intake pipe and the exhaust pipe, and the directions of the valves are respectively inward conduction and outward blockage, and outward conduction and inward blockage.

[0017] As a further technical solution of the present invention, the internal movable sleeve of the gas storage pipe is provided with a piston plate, the bottom end of the piston plate is fixedly connected to a piston rod located inside the gas storage pipe, the bottom end of the piston rod passes through the bottom end of the gas storage pipe and is fixedly connected to a mounting seat, and the bottom end of the exhaust pipe passes through the top end of the discharge box and is located directly above the discharge port.

[0018] As a further technical solution of the present invention, one end of the mounting seat away from the piston rod is movably connected to a first connecting rod via a rotating shaft, and one end of the first connecting rod away from the mounting seat is movably connected to a second connecting rod via a rotating shaft, and the other end of the second connecting rod is fixedly connected to the right side of the main shaft.

[0019] And during the discharging process, due to the rotation of the main shaft, the second connecting rod can be driven to rotate synchronously, and the first connecting rod will swing accordingly. With the continuous rotation of the second connecting rod, the piston rod can be driven to move up and down reciprocatingly. When the piston rod moves downward, the piston plate can be driven to move downward, thereby generating negative pressure inside the air storage pipe, and air is sucked into the air storage pipe through the air intake pipe. When the piston plate moves up, the air inside the air storage pipe is discharged through the exhaust pipe, and enters the interior of the discharge box through the exhaust pipe and acts on the top of the discharge port, thereby completing the discharging with the assistance of high-speed airflow.

[0020] By utilizing the active discharging process of the device to achieve rapid discharge of feed particles, the active suction and exhaust of the air storage pipe are achieved through its rotation, and the discharge material is blown by high-speed airflow to reduce the problem of feed retention that is prone to occur in traditional devices during discharge, reduce the number of manual assisted discharge, and improve discharge efficiency.

[0021] A method for detecting the quality of granular poultry feed comprises the following steps: S1: Before testing the pelletized feed, firstly, the upper telescopic rod can be rotated to make the upper movable screen rotate relative to the fixed screen to adjust the maximum particle size. After the adjustment is completed, the lower telescopic rod is rotated to make the lower movable screen rotate relative to the fixed screen to adjust the minimum particle size. The particles within this particle size range are qualified products. At the same time, the sealing plug is pulled upwards to open the waste port at the top and the material is injected to complete the preliminary operation. S2: At this time, the vibration table can be turned on to drive the frame and the detection tank to rotate. At this time, the particles larger than the set particle size range will stay on the top of the upper fixed screen, while the particles smaller than the set particle size range will be located at the bottom of the lower fixed screen, completing the layered screening, and the qualified granular feed can stay between the upper and lower movable screens to complete the detection process; S3: At the same time, the motor can be turned on to drive the driving gear to rotate until the first bevel gear is driven to rotate. At this time, the guide rod will move circumferentially, and the qualified feed on the top of the movable screen below can be gradually swept into the inside of the discharge box, and discharged through the discharge port at the bottom of the discharge box to complete the discharge; S4: When the main shaft rotates, it can drive the second connecting rod to swing, and finally drive the piston plate to move up and down reciprocatingly, so as to realize the air suction and exhaust process inside the locking frame. When the locking frame is exhausted, the flowing air can be used to act on the discharge port to assist in completing the discharge process and reduce the retention of feed.

[0022] The beneficial effects of the present invention are as follows: 1. The present invention sets two sets of upper and lower fixed screens and movable screens, and adjusts the overlapping aperture sizes of the upper and lower fixed screens and movable screens respectively, so that the device only needs to pour the feed and cooperate with the vibration of the vibration table to quickly screen out oversized and undersized feed particles and quickly obtain qualified feed particles. The entire operation process is relatively simple and can be completed without multiple transfers, which effectively improves the detection efficiency.

[0023] 2. The present invention realizes rapid discharge of feed particles by utilizing the process of active discharge of the device, and realizes active suction and exhaust of the air storage pipe through its rotation action, and blows the discharged material through high-speed airflow, thereby reducing the problem of feed retention that is prone to occur in traditional devices during discharge, reducing the number of times of manual assisted discharge, and improving discharge efficiency.

[0024] 3. The present invention utilizes the vibration during screening and cooperates with the main shaft and the first bevel gear as well as the second bevel gear and the power assembly, so that the device can automatically export qualified feed particles during screening, avoid the accumulation of feed particles, and achieve rapid discharge of qualified feed. The entire process is completed quickly, further improving the overall screening and detection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The movable screen 6 rotates relative to the fixed screen 5. When the telescopic rods 9 are in the initial state, the sealing plugs 10 are movably connected with the waste port 11 and the waste port 11 is sealed.

[0031] Embodiment: Before performing quality screening test, it is necessary to set the qualified particle size range according to the quality requirements, and according to the particle size range, rotate the upper telescopic rod 9 so that the upper telescopic rod 9 and the movable screen 6 rotate relative to the fixed screen 5, adjust the size of the overlapping screening hole of the upper fixed screen 5 and the movable screen 6 to ensure that it meets the maximum particle size requirement, and at the same time, according to the minimum particle size, rotate the lower telescopic rod 9 to adjust the size of the overlapping screening hole of the lower fixed screen 5 and the movable screen 6 to ensure that it meets the minimum particle size requirement. After the adjustment is completed, it is necessary to pull the sealing plug 10 upwards so that the telescopic rod 9 and the movable screen 6 rotate relative to the fixed screen 5. The retracted rod 9 is stretched and drives the sealing plug 10 to move upward, at which time the upper waste port 11 is exposed, and the material is poured into the interior of the detection tank 3 through the upper waste port 11. At the same time, the vibration table 2 is turned on to drive the detection tank 3 to vibrate to complete the screening.

[0032] By setting two sets of upper and lower fixed screens 5 and movable screens 6, and adjusting the overlapping aperture sizes of the two sets of upper and lower fixed screens 5 and movable screens 6 respectively, the device only needs to pour the feed, and cooperate with the vibration of the vibration table 2 to quickly screen out oversized and undersized feed particles and quickly obtain qualified feed particles.

The bottom end of the driving gear 153 is meshedly connected with a driven gear 154, and the middle part of the driven gear 154 is fixedly sleeved with the main shaft 12.

[0034] When qualified feed particles stay between the two movable screens 6 after screening, the feed particles can be accumulated on the top of the lower movable screen 6. At the same time, during screening, the motor 152 can be turned on synchronously to drive the driving gear 153 to rotate. At this time, the driven gear 154 below rotates accordingly, and at the same time drives the main shaft 12 to rotate. At this time, the second bevel gear 14 on the left side of the main shaft 12 rotates accordingly, and drives the first bevel gear 13 in the meshing state to rotate, and finally drives the movable shaft 7 to rotate relative to the two movable screens 6. At this time, the guide rod 8 rotates circumferentially relative to the lower movable screen 6 and cleans the feed particles on the movable screen 6. As the screening proceeds, with the vibration, the qualified feed can be introduced into the inside of the discharge box 4 in sequence, and finally discharged through the discharge port 17, completing the active discharge process of qualified products.

9. A granular poultry feed quality detection device according to claim 8, characterized in that: One end of the mounting seat (167) away from the piston rod (164) is movably connected to a first connecting rod (168) via a rotating shaft, and one end of the first connecting rod (168) away from the mounting seat (167) is movably connected to a second connecting rod (169) via a rotating shaft, and the other end of the second connecting rod (169) is fixedly connected to the right side of the main shaft (12).

10. The method of the granular poultry feed quality detection device according to claim 9, characterized in that: The following steps are involved: S1: Before testing the pelletized feed, the upper telescopic rod (9) is first rotated to rotate the upper movable screen (6) relative to the fixed screen (5) to adjust the maximum particle size. After the adjustment is completed, the lower telescopic rod (9) is rotated to rotate the lower movable screen (6) relative to the fixed screen (5) to adjust the minimum particle size. Particles within the particle size range are qualified products. At the same time, the sealing plug (10) is pulled upward to open the upper waste material port (11) and inject the material to complete the preliminary operation; S2: At this time, the vibration table (2) can be turned on to drive the frame (1) and the detection tank (3) to rotate. At this time, particles larger than the set particle size range will stay on the top of the upper fixed screen (5), while particles smaller than the set particle size range will be located at the bottom of the lower fixed screen (5), completing the stratified screening, and qualified granular feed will stay between the upper and lower movable screens (6), completing the detection process; S3: At the same time, the motor (152) can be turned on to drive the driving gear (153) to rotate until the first bevel gear (13) is driven to rotate. At this time, the guide rod (8) then moves in a circumferential direction, and the qualified feed on the top of the movable screen (6) below can be gradually swept into the inside of the discharge box (4) and discharged through the discharge port (17) at the bottom of the discharge box (4), thereby completing the discharge; S4: When the main shaft (12) rotates, it can drive the second connecting rod (169) to swing, and finally drive the piston plate (163) to move up and down reciprocatingly, thereby realizing the suction and exhaust process inside the locking frame (161). When the locking frame (161) is exhausted, the flowing air can be used to act on the discharge port (17), thereby assisting the discharge process and reducing the retention of feed.
