[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figures 1 to 3 、 Figure 8 A feeding device for a hawthorn production device includes a screening box 1 and a support frame 2. Two support frames 2 are provided and are symmetrically and evenly distributed on both sides of the screening box 1. A conveyor belt 3 for conveying hawthorn is rotatably installed above each support frame 2. A feeding port 4 is fixedly installed on the top of the screening box 1. Discharge pipes 5 are fixedly connected to both sides of the screening box 1, and each discharge pipe 5 is located on the top of the conveyor belt 3.

[0033] The inner cavity of the conveyor belt 3 is rotatably connected to a conveying mechanism for filtering out bad hawthorn fruits. The air-filled roller 601 of the conveyor mechanism is rotatably connected to the conveyor belt 3 to convey the hawthorns while also removing hawthorns with damaged surfaces.

[0034] The inner cavity of the screening box 1 is fixedly installed with a screening mechanism for removing empty hawthorn fruits. The filter box 701 of the screening mechanism is fixedly connected to the discharge pipe 5 to transport good hawthorn fruits.

[0035] Example 2: Please refer to Figures 1 to 6 , a feeding device for a hawthorn production device, which differs from Example 1 in that the conveying mechanism includes a supporting plate 602, the supporting plate 602 is fixedly connected to the top surface of the support frame 2, and the conveyor belt 3 is rotatably connected to the inner cavity of the supporting plate 602, the inner cavity of the inflation roller 601 is fixedly plugged with an inflation tube 603 for changing the gas content inside the inflation roller 601, both ends of the inflation tube 603 pass through the conveyor belt 3 and are fixedly sleeved with a runner 604 for driving the inflation roller 601 to rotate, and the interior of the inflation roller 601 is fixedly connected to a supporting mechanism for supporting the inflation roller 601;

[0036] Specifically, the outer wall of the inflation tube 603 is provided with a plurality of air outlet holes, and air is injected or sucked into the interior of the inflation roller 601 through the inflation tube 603 to change the gas content in the inner cavity of the inflation roller 601. In the initial stage, the inflation roller 601 is in a semi-inflated state. At this time, its outer wall moderately shrinks halfway toward the axis, thereby forming an arc groove that fits the shape of the hawthorn, allowing the hawthorn to fall accurately between the two inflation rollers 601. With the help of the arc groove, the position of the hawthorn is effectively and accurately defined, thereby preventing the hawthorn from unnecessary displacement and falling during the transportation process of the hawthorn, and ensuring the stability and reliability of the transportation process; when it is detected that the surface of the hawthorn being transported is damaged, the inflation tube 603 will quickly inject gas into the interior of the inflation roller 601 in the initial semi-inflated state until the interior is fully inflated. In this process, the outer wall of the inflation roller 601 becomes tight due to the filling of the internal gas. This tight state will generate an upward squeezing force, so that the broken hawthorns are smoothly pushed to the top surface of the inflation roller 601, providing convenient conditions for the subsequent operation of accurately removing the broken hawthorns; in addition, the inflation tube 603 also has the function of sucking gas, which can suck air into the inflation roller 601 in the initial state. As the gas is extracted, the air pressure inside the inflation roller 601 decreases, causing its outer wall to further shrink toward the axis, so that the curvature of the arc groove increases accordingly, thereby increasing the distance between the two inflation rollers 601, so as to easily and efficiently release the hawthorns, effectively improving the intelligence level and operational flexibility of the entire device, so that it can better adapt to various complex situations and diversified needs in the hawthorn production process (please refer to the detailed instructions for details). Figure 6 );

[0037] More specifically, the inner cavity of the supporting plate 602 is provided with a rotating groove for providing rotation of the conveyor belt 3, and the conveyor belt 3 is located in the rotating groove. The inner cavity of the supporting plate 602 is provided with a moving groove for providing rotation of the runner 604, and the runner 604 is located in the moving groove. There are two moving grooves and they are symmetrically and evenly distributed on both sides of the rotating groove.

[0038] The conveying mechanism also includes a gas delivery mechanism for supplying gas to the interior of the inflation tube 603. The gas delivery mechanism changes the gas content in the inner cavity of the inflation roller 601 to remove bad fruits and screen the hawthorns. The inner wall of the conveyor belt 3 is rotatably connected to the end away from the gas delivery mechanism. A drive mechanism for driving the conveyor belt 3 is rotatably connected to the support plate 602.

[0039] The air delivery mechanism includes an air suction turntable 605, which is rotatably connected to the top surface of the support plate 602. The outer wall of the air suction turntable 605 is fixedly connected to a plurality of air suction pipes 606 for extracting the air inside the inflation roller 601;

[0040] Specifically, the ends of the suction pipe 606 and the inflation pipe 603 that fit together are fixedly connected to a magnetic block 607, and the two are magnetically connected via the magnetic block 607, ensuring the connection reliability and adjustability of the connection state between the suction pipe 606 and the inflation pipe 603, providing a convenient and flexible connection foundation for the efficient operation of the entire device and the gas transmission process;

[0041] The end of the support plate 602 close to the suction pipe 606 is provided with three screening slots, and the bottom end of each screening slot is fixedly connected to a connecting pipe 608 for connecting to processing equipment;

[0042] Specifically, the sizes of the slots of the three screening slots are distributed in order from small to large, and the air inside the inflation roller 601 is continuously sucked by the suction pipe 606, so that the distance between the two inflation rollers 601 is gradually increased, thereby releasing the clamping restriction on the hawthorns, and the hawthorns fall onto the supporting plate 602, roll into the screening slots of appropriate size, and are discharged from the connecting pipe 608, so as to achieve a more detailed screening operation on the hawthorns before they enter the processing equipment. The hawthorns can be orderly sorted into different screening slots according to their size, shape or other physical characteristics, thereby achieving a more accurate screening effect, providing higher quality hawthorn raw materials for subsequent processing, and improving the efficiency and product quality of the entire hawthorn production and processing process;

[0043] An air injection pipe 609 for inflating the inside of the air roller 601 is installed on one side of the air suction turntable 605, and the air injection pipe 609 is magnetically connected to the air inflation pipe 603 through a magnetic block 607;

[0044] Specifically, the bottom end of the air injection pipe 609 is fixedly connected to the supporting plate 602. A guide plate 610 for guiding the movement of the broken hawthorns is installed on one side of the air injection pipe 609. The guide plate 610 is located on the top surface of the conveyor belt 3 and the bottom end of the guide plate 610 is fixedly connected to the supporting plate 602. The conveyor belt 3 is slightly inclined toward one side of the guide plate 610 to further guide the movement direction of the hawthorns.

The gas injection tube 603 passes through and connects with the two gas outlets in sequence to ensure that the gas inside the gas roller 601 can reach a full state after gas injection, providing stable and reliable gas support for the subsequent operation of removing bad fruits;

[0046] In order to reset the inflation roller 601 after air absorption, a reset tube 612 is installed on one side of the air injection tube 609, and the reset tube 612 is magnetically connected to the inflation tube 603 through a magnetic block 607;

[0047] Specifically, the bottom end of the reset tube 612 is fixedly connected to the support plate 602, and the label ring 611 is also provided with two air outlets to ensure that the reset tube 612 stably injects air into the inflatable roller 601 to help the inflatable roller 601 return to its initial state;

[0048] More specifically, the bottom ends of the air suction turntable 605, the air injection pipe 609 and the reset pipe 612 are all fixedly connected to the air pump 613 through pipes, and the air pump 613 is fixedly connected to the top surface of the support frame 2;

[0049] The driving mechanism includes a driving wheel 614, which is rotatably connected to the inside of the conveyor belt 3. The top surface of the support frame 2 is fixedly connected to a driving motor 615, and the output shaft of the driving motor 615 is fixedly connected to the driving wheel 614;

[0050] Specifically, the inner wall of the conveyor belt 3 is fixedly connected with a toothed belt 616, and there are two drive wheels 614, both of which are engaged with the toothed belt 616. One drive wheel 614 is fixedly sleeved on the outer wall of the output shaft of the drive motor 615, and the other drive wheel 614 is fixedly sleeved on the outer wall of the bottom end pipe of the suction turntable 605. The two drive wheels 614 cooperate to drive the conveyor belt 3 to rotate and also drive the suction turntable 605 to rotate synchronously, so that the suction pipe 606 and the inflation pipe 603 can be accurately connected;

[0051] See also Figure 7The top of the supporting plate 602 is fixedly connected to a fixing frame 617, and the inner wall of the fixing frame 617 is fixedly connected to a visual inspection instrument 618 for scanning damaged hawthorns and a light board for auxiliary inspection, and two light boards are set symmetrically and evenly on both sides of the visual inspection instrument 618.

[0052] See also Figure 5 The supporting mechanism includes a moving rod 619, which is slidably inserted into the interior of the inflation tube 603. One end of the moving rod 619 is fixedly connected to a circular arc plate 620. Springs 621 are installed on both sides of the moving rod 619, and the springs 621 are respectively fixedly connected to the circular arc plate 620 and the inflation tube 603. Both ends of the interior of the inflation roller 601 are fixedly connected to support plates 622, and the support plates 622 are fixedly sleeved on the outer wall of the inflation tube 603.

[0053] Example 3: Please refer to Figures 8 to 10 , a feeding device for a hawthorn production device, which differs from Example 1 in that the screening mechanism includes a screening plate 702, which is rotatably connected to the inner cavity of the screening box 1, and a power mechanism for driving the screening plate 702 to shake is fixedly connected to one side of the screening plate 702. The power mechanism drives the screening plate 702 to shake to remove residual leaves in the hawthorn raw material, and the filter box 701 is located below the screening plate 702. A water pipe 703 for injecting water to filter empty hawthorn fruits is fixedly connected to one side of the filter box 701. Water is injected into the inner cavity of the filter box 701 through the water pipe 703, so that the hollow hawthorns float up, and then the empty fruits are separated and taken out;

[0054] Specifically, the filter box 701 is fixedly connected to the inner wall of the screening box 1, and there are two screening plates 702, and the inner cavity of each screening plate 702 is provided with a filter hole. The filter holes of the two screening plates 702 are distributed in order from large to small. The screening plates 702 are provided with a certain inclination angle. A horizontal groove is provided inside one end of the lower point of the inclination of the screening plate 702, and a guide plate 704 for guiding the movement of large hawthorn fruits and leaves is fixedly installed at the bottom of the horizontal groove. A collection box 705 for collecting leaves is fixedly connected to the bottom end of the inner cavity of the screening box 1.

[0055] One end of the filter box 701 away from the water pipe 703 is fixedly connected to the discharge pipe 5. The outer wall of the water pipe 703 is provided with a valve for controlling the flow of the water pipe 703. The inner wall of the filter box 701 is fixedly installed with a monitor 706 for monitoring the water level. The outer wall of the filter box 701 is fixedly connected to a drain pipe 707 for draining the empty fruit.

[0056] Specifically, the size of the end of the discharge pipe 5 close to the filter box 701 is set to be able to pass only one hawthorn, so as to ensure that the discharge pipe 5 only transports one hawthorn between the two inflatable rollers 601, so as to facilitate subsequent detection operations. At the same time, in order to prevent the hawthorn from clogging the discharge pipe 5, the water inlet height of the water pipe 703 is consistent with the discharge pipe 5. When water is injected into the inner cavity of the filter box 701 by the water pipe 703, the hawthorn flow is impacted to prevent blockage. When the monitor 706 detects that the water level inside the filter box 701 is lower than that of the monitor 706, water exceeding the amount of water lacking in the filter box 701 will be injected, and the empty fruits that have been impacted and floated up will be discharged into the drain pipe 707. The drain pipes 707 of the two filter boxes 701 are fixedly connected to each other.

[0057] The bottom end of the water delivery pipe 703 is fixedly connected to a water pump, one end of which is fixedly connected to a water storage tank. The drainage pipe 707 is fixedly connected to the water storage tank, and one end of which is fixedly connected to a water outlet pipe.

[0058] The power mechanism includes a motor 708, which is fixedly connected to the inner wall of the screening box 1. The output shaft of the motor 708 is fixedly connected to the eccentric turntable 709. A rotating rod 710 is fixedly connected to one side of the eccentric turntable 709, and the rotating rod 710 is located at a non-center position of the eccentric turntable 709. The rotating rod 710 is fixedly connected to the screening plate 702.

[0059] The working principle of the present invention is:

[0060] First, the hawthorns enter from the feed port 4 at the top of the screening box 1, and the eccentric turntable 709 is driven to rotate by the rotation of the motor 708. Since the rotating rod 710 is located at the non-center of the eccentric turntable 709, the screening plate 702 is driven to shake, and the hawthorns move on the screening plate 702. The filter holes on the screening plate 702 can be used to perform preliminary screening of the hawthorns. The filter holes of the two screening plates 702 are distributed from large to small, which can preliminarily separate larger hawthorns from smaller hawthorns. The screened hawthorns pass through the filter holes and enter the filter box 701. Water is injected into the inner cavity of the filter box 701 through the water pipe 703, so that the hollow hawthorns float up. When the monitor 706 on the inner wall of the filter box 701 detects that the water level is lower than the set value, more water than the capacity of the filter box 701 will be injected, and the floating empty fruits will be flushed into the drain pipe 707 for discharge, while the normal hawthorns enter the inflation roller 601 on the conveyor belt 3 through the discharge pipe 5 for subsequent processing;

[0061] Initially, the inflation tube 603 adjusts the inflation roller 601 to a semi-inflated state, and the hawthorns fall into the arc groove between the two inflation rollers 601. The driving motor 615 drives the driving wheel 614 to rotate, thereby driving the conveyor belt 3 to rotate. At the same time, under the action of friction, the inflation roller 601 will move laterally and rotate along with the conveyor belt 3, realizing the transportation and rotation of the hawthorns.

[0062] When the inflatable roller 601 drives the hawthorn to move to the bottom of the fixed frame 617, the hawthorn on the conveyor belt 3 is scanned by the visual inspection device 618. When damaged hawthorn is detected, the label ring 611 is used to mark the current two inflatable rollers 601;

[0063] The inflation roller 601 continues to move to the side of the gas injection tube 609. The sensor block inside the gas injection tube 609 recognizes the label ring 611 and uses the magnetic block 607 to connect the inflation roller 601 and the gas injection tube 609. Gas is accurately injected into the corresponding gas injection tube 603, so that the gas inside the inflation roller 601 is filled with gas, and the outer wall of the inflation roller 601 is tightened, pushing the broken hawthorn to the top surface of the inflation roller 601. Then, the guide plate 610 is used to guide the broken hawthorn to move to one side so that it can be removed later.

[0064] When the aeration roller 601 conveying undamaged hawthorns and the aeration roller 601 from which bad hawthorns have been removed move to one side of the suction turntable 605, the magnetic block 607 is used to connect the aeration roller 601 and the suction pipe 606. The air inside the aeration roller 601 is gradually sucked out through the suction pipe 606. The air pressure inside the aeration roller 601 decreases, the outer wall further contracts toward the axis, the curvature of the arc groove increases, and the distance between the two aeration rollers 601 increases. The hawthorns will fall onto the supporting plate 602 and roll into different screening slots according to their size. They are then discharged from the connecting pipe 608 into the processing equipment to achieve size screening of the hawthorns.

[0065] Finally, the inflation roller 601 without gas inside is moved to the side of the reset tube 612, and the magnetic block 607 is used to connect the inflation roller 601 and the reset tube 612. The two air outlets of the reset tube 612 ensure that part of the gas is stably injected into the interior of the inflation roller 601, so that the inflation roller 601 can return to its initial state, and the air pump 613 is used to provide a gas source for the suction turntable 605, the gas injection tube 609 and the reset tube 612, thereby realizing the gas extraction, injection and reset operations.

[0066] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
