Description

Technical Field

[0001] The invention relates to the technical field of bayberry quality screening, and in particular to an automatic screening device and a screening method for bayberry quality detection. Background Art

[0002] Bayberry quality screening refers to the process of evaluating and classifying bayberry's quality indicators such as appearance, size, color, sugar content and hardness according to certain standards and methods. This process helps to ensure that the bayberries sold on the market meet specific quality requirements. It also helps producers and distributors optimize product grading, improve economic benefits and market competitiveness. Quality screening can be done by manual visual inspection and measurement, or by using automated equipment for more accurate and efficient screening. Through screening, bayberry varieties with excellent fruit appearance and internal quality can be selected, thereby improving the market value of the fruit and consumer acceptance.

[0003] According to the announcement number CN113318982B, a screening device for processing bayberry is disclosed, including an outer shell, a screening cylinder is provided inside the outer shell, the screening cylinder is rotatably connected to the outer shell, a motor is provided at the bottom of the screening cylinder, and the output end of the motor is connected to the bottom of the screening cylinder; a first screening plate, a second screening plate and a third screening plate are provided in the screening cylinder from top to bottom, the first screening plate, the second screening plate and the third screening plate are all arranged in an inverted cone shape, and the aperture of the sieve hole of the second screening plate is smaller than the aperture of the sieve hole of the first screening plate, and the aperture of the sieve hole of the third screening plate is smaller than the aperture of the sieve hole of the second screening plate.

[0004] By adopting the above technical scheme, the motor is started, the motor rotates intermittently, and drives the screening drum to rotate intermittently. When the screening drum rotates, the bayberry rolls to the edge on the first screening plate under the action of centrifugal force. When the screening drum stops rotating, the bayberry gathers to the center of the first screening plate under the action of gravity, so as to achieve the screening effect of the bayberry. After a period of time, the bayberry screening is completed. Compared with manual screening, the present invention is portable and efficient. However, in the above technical scheme, since the flesh on the surface of the bayberry is relatively fragile and there is a certain distance between the screening plates of the above device, the bayberry is easily damaged when it falls from the upper screening plate to the lower screening plate. At the same time, during the screening process, the bayberry may be blocked in the through holes of the screening plate, which may easily cause a certain impact on the subsequent screening, increase the probability of damage to the bayberry during screening, and also be inconvenient to transport the screened bayberry, which may easily affect the screening efficiency of the bayberry.

[0008] The conveying mechanism includes a fixed frame, the bottom surface of the fixed frame is fixedly connected to the upper surface of the bottom plate, the inner wall of the fixed frame is rotatably connected to two rotating shafts, the outer surfaces of the two rotating shafts are rotatably connected to a conveyor belt, the right end of one of the rotating shafts is fixedly connected to a rotating motor, the left side of the rotating motor is fixedly connected to the right side of the fixed frame, the upper surface of the fixed frame is fixedly connected to a baffle, and the left side of the fixed frame is fixedly connected to a conveying platform.

[0009] Preferably, four first supporting legs are fixedly connected to the bottom surface of the bottom plate, and the bottom surface of each of the first supporting legs is fixedly connected to the first base.

[0010] Preferably, two second supporting legs are fixedly connected to the bottom surface of the fixing frame, and the bottom surface of each of the second supporting legs is fixedly connected to the second base.

[0011] Preferably, a reinforcement frame is fixedly connected to the outer surface of the rotating motor, and the left side surface of the reinforcement frame is fixedly connected to the right side surface of the fixing frame.

[0012] Preferably, a guide frame is fixedly connected to the bottom surface of the fixed frame, and a soft cushion is fixedly connected to the inner wall of the guide frame.

[0013] Preferably, two second partition plates are fixedly connected to the inner wall of the guide frame, the bottom surface of each of the second partition plates is in contact with the upper surface of the cushion, and the upper surface of each of the second partition plates is fixedly connected to the bottom surface of the fixed frame.

[0014] Preferably, the inner wall of the guide frame is slidably connected to a collecting box, and the inner wall of the collecting box is fixedly connected to two first partition plates.

[0015] Preferably, handles are fixedly connected to both side surfaces of the collection box, and four universal wheels are fixedly connected to the bottom surface of the collection box.

[0016] Preferably, a reinforcement block is fixedly connected to the right side surface of the fixed box, and the upper surface of the reinforcement block is fixedly connected to the bottom surface of the bottom plate.

[0017] A screening method for an automatic screening device for bayberry quality detection specifically comprises the following steps:

[0018] S1: When the staff needs to use the device to screen the bayberry, the staff first places the screened bayberry on the surface of the conveyor belt;

[0019] S2: Then turn on the forward and reverse motors. After the forward and reverse motors are turned on, they can generate power rotation. The rotation of the forward and reverse motors can drive one end of the gear steering gear to rotate. The rotation of one end of the gear steering gear can drive the other end and the threaded rod on the other end to rotate. Under the action of the rotation of the threaded rod, the push block on the surface of the threaded rod can be driven to rise. The rise of the push block can push the lifting frame to rise. During the rise of the lifting frame, it can drive the internal connecting block to move. The connecting block can pull one end of the screening shaft to rise a part, so as to form a situation where one end is high and the other end is low, which is convenient for the bayberry between the screening shafts to roll and move;

[0020] S3: Then the staff turns on the rotating motor, which can generate power to rotate after it is turned on. The rotation of the rotating motor can rotate a rotating shaft. When a rotating shaft 305 rotates, it can drive the conveyor belt and the other rotating shaft to rotate, thereby driving the bayberries on the surface to move. When the bayberries move to the tail of the conveyor belt, they can be blocked by the baffle. The baffle can change the direction of the movement of the bayberries when they move. Then the bayberries can roll down to the surface of the screening shaft through the conveyor platform for screening. When the bayberries to be screened are introduced to the surface of the screening shaft, the screening shaft is thick at one end and thin at the other end. The gap between the two screening shafts will become larger and larger, so that the screening work can be automatically completed when the bayberries roll;

[0021] S4: Then the bayberries of different sizes will fall at different positions of the screening axis, and the fallen bayberries will be introduced into the collection box through the guide frame below, so as to complete the screening of the bayberries.

[0022] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0023] First, the present invention sets a screening shaft, a connecting block, a lifting frame, a forward and reverse motor, a gear steering gear, a threaded rod and a pushing block, so that under the action of the forward and reverse motor, the rotation of the forward and reverse motor can drive one end of the gear steering gear to rotate, and the rotation of one end of the gear steering gear can drive the other end and the threaded rod on the other end to rotate. Under the action of the rotation of the threaded rod, the pushing block on the surface of the threaded rod can be driven to rise, and the rising of the pushing block can push the lifting frame to rise. During the rising process of the lifting frame, the internal connecting block can be driven to move, and the connecting block can pull one end of the screening shaft to rise a part, thereby forming a situation where one end is high and the other end is low, which is convenient for the bayberry between the screening shafts to roll and move. At the same time, since the screening shaft is thick at one end and thin at the other end, the gap between the two screening shafts will become larger and larger, so that the screening work can be automatically completed when the bayberry rolls, and at the same time, it can also effectively avoid damage during screening.

[0024] Second, the present invention arranges a rotating motor, a rotating shaft, a conveyor belt, a baffle and a conveying platform, so that under the action of the rotating motor, the rotating motor can rotate one rotating shaft, and when one rotating shaft rotates, it can drive the conveyor belt and the other rotating shaft to rotate, thereby driving the bayberries on the surface to move. At the same time, the baffle can change the direction of the movement of the bayberries when the bayberries move, and roll them to the surface of the screening mechanism through the conveying platform for screening, thereby facilitating the transportation of the screened bayberries and improving the screening efficiency of the device.

At the same time, since the screening shaft 202 is thick at one end and thin at the other end, the gap between the two screening shafts 202 will become larger and larger, so that the screening work can be automatically completed when the bayberries roll.

[0042] Embodiment 2

[0043] See also Figure 1-6 The conveying mechanism 3 includes a fixed frame 301, the bottom surface of the fixed frame 301 is fixedly connected to the upper surface of the bottom plate 1, the inner wall of the fixed frame 301 is rotatably connected to two rotating shafts 305, the outer surfaces of the two rotating shafts 305 are rotatably connected to a conveyor belt 306, the right end of one of the rotating shafts 305 is fixedly connected to a rotating motor 304, the left side of the rotating motor 304 is fixedly connected to the right side of the fixed frame 301, the upper surface of the fixed frame 301 is fixedly connected to a baffle 302, and the left side of the fixed frame 301 is fixedly connected to a conveying platform 303.

[0044] Four first supporting legs 4 are fixedly connected to the bottom surface of the base plate 1, and the bottom surface of each first supporting leg 4 is fixedly connected to a first base 5. By setting the first supporting legs 4 and the first base 5, a good supporting effect can be provided for the base plate 1, so that it can be used stably for work.

[0045] The outer surface of the rotating motor 304 is fixedly connected with a reinforcement frame 8, and the left side of the reinforcement frame 8 is fixedly connected to the right side of the fixed frame 301. By setting the reinforcement frame 8, the stability effect of the rotating motor 304 can be further increased, so that it can rotate more stably.

[0046] A reinforcing block 16 is fixedly connected to the right side of the fixed box 205, and the upper surface of the reinforcing block 16 is fixedly connected to the bottom surface of the base plate 1. By setting the reinforcing block 16, the connection effect between the fixed box 205 and the base plate 1 can be further increased, so that the connection can be more stably performed.

[0047] The specific implementation method of this embodiment is as follows: first, the staff turns on the power of the rotating motor 304 so that it can be in a stable power-on state. Later, when the screened bayberries need to be transported, the staff places the bayberries on the conveyor belt 306 and then turns on the rotating motor 304. After the rotating motor 304 is turned on, it can generate power rotation. The rotation of the rotating motor 304 can rotate a rotating shaft 305. When one rotating shaft 305 rotates, it can drive the conveyor belt 306 and the other rotating shaft 305 to rotate, thereby driving the bayberries on the surface to move. When the bayberries move to the tail of the conveyor belt 306, they can be blocked by the baffle 302. The baffle 302 can change the direction of the movement of the bayberries when they move. Then the bayberries can roll onto the surface of the screening mechanism 2 through the conveying platform 303 for screening, thereby facilitating the transportation of the screened bayberries.

[0048] The working principle of the present invention is as follows: first, the staff turns on the power of the forward and reverse motor 206 and the rotating motor 304 so that they can be in a stable power-on state. When the staff needs to use the device to screen bayberries, the staff first places the screened bayberries on the surface of the conveyor belt 306, and then turns on the forward and reverse motor 206. After the forward and reverse motor 206 is turned on, it can generate power rotation. The rotation of the forward and reverse motor 206 can drive one end of the gear diverter 207 to rotate, and the rotation of one end of the gear diverter 207 can drive the other end and the threaded rod 208 on the other end to rotate. Under the action of the rotation of the threaded rod 208, the push block 209 on the surface of the threaded rod 208 can be driven to rise. The rise of the push block 209 can push the lifting frame 204 to rise. During the rise of the lifting frame 204, the internal connecting block 203 can be driven to move. The connecting block 203 can pull one end of the screening shaft 202 to rise a part, thereby forming a situation where one end is high and the other end is low, which is convenient for screening the bayberries between the screening shafts 202. Rolling movement, then the staff turns on the rotating motor 304. After the rotating motor 304 is turned on, it can generate power rotation. The rotation of the rotating motor 304 can rotate a rotating shaft 305. When one rotating shaft 305 rotates, it can drive the conveyor belt 306 and the other rotating shaft 305 to rotate, thereby driving the bayberries on the surface to move. When the bayberries move to the tail of the conveyor belt 306, they can be blocked by the baffle 302. The baffle 302 can change the direction of the movement of the bayberries when the bayberries move. Then the bayberries can roll to the surface of the screening shaft 202 through the conveyor platform 303 for screening. When the bayberries to be screened are introduced into the surface of the screening shaft 202, the screening shaft 202 is thick at one end and thin at the other end. The gap between the two screening shafts 202 will become larger and larger, so that the screening work can be automatically completed when the bayberries roll, and then bayberries of different sizes will fall at different positions of the screening shaft 202, and the fallen bayberries will be introduced into the collection box 9 through the guide frame 13 below, thereby completing the screening work of the bayberries.

[0049] A screening method for an automatic screening device for bayberry quality detection specifically comprises the following steps:

[0050] S1: When the staff needs to use the device to screen the bayberries, the staff first places the screened bayberries on the surface of the conveyor belt 306;

[0051] S2: Then turn on the forward and reverse motor 206. After the forward and reverse motor 206 is turned on, it can generate power rotation. The rotation of the forward and reverse motor 206 can drive one end of the gear steering device 207 to rotate. The rotation of one end of the gear steering device 207 can drive the other end and the threaded rod 208 on the other end to rotate. Under the action of the rotation of the threaded rod 208, the push block 209 on the surface of the threaded rod 208 can be driven to rise. The rise of the push block 209 can push the lifting frame 204 to rise. During the rise of the lifting frame 204, the internal connecting block 203 can be driven to move. The connecting block 203 can pull one end of the screening shaft 202 to rise a part, so as to form a situation where one end is high and the other end is low, which is convenient for the waxberries between the screening shafts 202 to roll and move;

[0052] S3: Then the staff turns on the rotating motor 304. After the rotating motor 304 is turned on, it can generate power to rotate. The rotation of the rotating motor 304 can rotate a rotating shaft 305. When one rotating shaft 305 rotates, it can drive the conveyor belt 306 and the other rotating shaft 305 to rotate, thereby driving the bayberries on the surface to move. When the bayberries move to the tail of the conveyor belt 306, they can be blocked by the baffle 302. The baffle 302 can change the direction of the movement of the bayberries when they move. Then the bayberries can roll through the conveyor platform 303 to the surface of the screening shaft 202 for screening. When the bayberries to be screened are introduced to the surface of the screening shaft 202, the screening shaft 202 is thick at one end and thin at the other end. The gap between the two screening shafts 202 will become larger and larger, so that the screening work can be automatically completed when the bayberries roll;

[0053] S4: Then the bayberries of different sizes will fall at different positions of the screening axis 202, and the fallen bayberries will be introduced into the collecting box 9 through the guide frame 13 below, so as to complete the screening of the bayberries.

The automatic screening device for waxberry quality detection according to claim 1, characterized in that: A reinforcing block (16) is fixedly connected to the right side surface of the fixed box (205), and the upper surface of the reinforcing block (16) is fixedly connected to the bottom surface of the bottom plate (1).

10. A screening method for an automatic screening device for bayberry quality detection according to any one of claims 1 to 9, characterized in that: The specific steps include: S1: When the staff needs to use the device to screen the bayberries, the staff first places the screened bayberries on the surface of the conveyor belt (306); S2: Then, the forward and reverse motor (206) is turned on. After being turned on, the forward and reverse motor (206) can generate power rotation. The rotation of the forward and reverse motor (206) can drive one end of the gear steering gear (207) to rotate. The rotation of one end of the gear steering gear (207) can drive the other end and the threaded rod (208) on the other end to rotate. Under the action of the rotation of the threaded rod (208), the push block (209) on the surface of the threaded rod (208) can be driven to rise. The rise of the push block (209) can push the lifting frame (204) to rise. During the process of the lifting frame (204) rising, it can drive the internal connection block (203) to move. The connection block (203) can pull one end of the screening shaft (202) to rise a part, so as to form a situation where one end is high and the other end is low, so that the bayberries between the screening shafts (202) can be convenient for rolling movement; S3: Then the staff turns on the rotating motor (304). After the rotating motor (304) is turned on, it can generate power to rotate. The rotation of the rotating motor (304) can rotate a rotating shaft (305). When one rotating shaft (305) rotates, it can drive the conveyor belt (306) and the other rotating shaft (305) to rotate, thereby driving the bayberries on the surface to move. When the bayberries move to the tail of the conveyor belt (306), they can be blocked by the baffle (302). The baffle (302) can change the direction of the movement of the bayberries when they move. Then the bayberries can roll down to the surface of the screening shaft (202) through the conveyor platform (303) for screening. When the bayberries to be screened are introduced to the surface of the screening shaft (202), the screening shaft (202) is thick at one end and thin at the other end. The gap between the two screening shafts (202) will become larger and larger, so that the screening work can be automatically completed when the bayberries roll; S4: Then, bayberries of different sizes will fall at different positions of the screening shaft (202), and the fallen bayberries will be introduced into the collection box (9) through the guide frame (13) below, thereby completing the screening of the bayberries.
