DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1 to Figure 3 , Figure 8 A feeding device for a hawthorn production device comprises 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 feed port 4 is fixedly installed at 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 bad hawthorn fruits, and the air-filled roller 601 of the conveying mechanism is rotatably connected to the conveyor belt 3 to convey the hawthorns and also remove the 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, and 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 Figure 1 to Figure 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 inflatable roller 601 is fixedly plugged with an inflatable tube 603 for changing the gas content inside the inflatable roller 601, both ends of the inflatable tube 603 are passed through the conveyor belt 3 and are fixedly sleeved with a rotating wheel 604 for driving the inflatable roller 601 to rotate, and the interior of the inflatable roller 601 is fixedly connected with a supporting mechanism for supporting the inflatable 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, and at this time, its outer wall moderately shrinks half toward the axis, thereby forming an arc groove that fits the shape of the hawthorn, so that the hawthorn can accurately fall 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 of the hawthorn, thereby 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 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 hawthorn is smoothly pushed to the top surface of the inflation roller 601, providing convenient conditions for the subsequent operation of accurately removing the broken hawthorn; 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, and the distance between the two inflation rollers 601 is increased, so as to easily and efficiently release the hawthorn, 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 details) Figure 6 );

[0037] More specifically, the inner cavity of the supporting plate 602 is provided with a rotating groove for providing the conveyor belt 3 with rotation, and the conveyor belt 3 is located in the rotating groove, and the inner cavity of the supporting plate 602 is provided with a moving groove for providing the rotating wheel 604 with rotation, and the rotating wheel 604 is located in the moving groove, and there are two moving grooves in total 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 providing gas to the inside of the gas filling tube 603, and the gas delivery mechanism changes the gas content in the inner cavity of the gas filling roller 601 to remove bad fruits and screen hawthorns. The inner wall of the conveyor belt 3 is rotatably connected to one end away from the gas delivery mechanism to drive the conveyor belt 3 to rotate, and the driving mechanism is rotatably connected to the supporting 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, and the outer wall of the air suction turntable 605 is fixedly connected with a plurality of air suction pipes 606 for extracting the internal air of the inflation roller 601;

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

[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 inflatable roller 601 is continuously sucked by the suction pipe 606, so that the distance between the two inflatable rollers 601 is gradually increased to release the clamping restriction on the hawthorn. The hawthorn falls onto the supporting plate 602, rolls into the screening slot of a suitable size, and is discharged from the connecting pipe 608, so as to achieve a more detailed screening operation on the hawthorn before the hawthorn enters the processing equipment, and can orderly sort the hawthorn into different screening slots according to the size, shape or other physical characteristics of the hawthorn, thereby achieving a more accurate screening effect, providing a higher quality hawthorn raw material for the subsequent processing process, and improving the efficiency and product quality of the entire hawthorn production and processing process;

[0044] Specifically, the bottom end of the air injection pipe 609 is fixedly connected to the supporting plate 602, and a guide plate 610 for guiding the movement of the broken hawthorn is installed on one side of the air injection pipe 609.

[0046] In order to reset the inflation roller 601 after air suction, 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, so as 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 an air pump 613 through pipelines, and the air pump 613 is fixedly connected to the top surface of the support frame 2;

[0050] Specifically, the inner wall of the conveyor belt 3 is fixedly connected with a toothed belt 616, and two driving wheels 614 are provided and both are meshed with the toothed belt 616. One driving wheel 614 is fixedly sleeved on the outer wall of the output shaft of the driving motor 615, and the other driving wheel 614 is fixedly sleeved on the outer wall of the bottom pipe of the suction turntable 605. The two driving wheels 614 cooperate to drive the conveyor belt 3 to rotate and also drive the suction turntable 605 to follow the synchronous rotation, 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 with a fixing frame 617, and the inner wall of the fixing frame 617 is fixedly connected with 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 distributed 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 an 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 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 is different from Example 1 in that the screening mechanism includes a screening plate 702, the screening plate 702 is rotatably connected to the inner cavity of the screening box 1, and one side of the screening plate 702 is fixedly connected with a power mechanism for driving the screening plate 702 to shake, and the screening plate 702 is driven by the power mechanism to shake to remove the leaves remaining in the hawthorn raw material, and the filter box 701 is located below the screening plate 702, and one side of the filter box 701 is fixedly connected with a water pipe 703 for injecting water to filter the empty hawthorn fruits, and 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 filtering hole, and the filter hole sizes of the two screening plates 702 are distributed in order from large to small. The screening plate 702 is provided with a certain inclination angle, and a horizontal groove is provided inside one end of the inclination low point 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 end of the horizontal groove, and 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. A monitor 706 for monitoring the water level is fixedly installed on the inner wall of the filter box 701. A drain pipe 707 for draining empty fruit is fixedly connected to the outer wall of the filter box 701.

[0056] Specifically, the size of the end of the discharge pipe 5 close to the filter box 701 is set to allow only one hawthorn to pass through, so as to ensure that the discharge pipe 5 only delivers one hawthorn between the two inflation 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 the water pipe 703 is used to inject water into the inner cavity of the filter box 701, the flow of hawthorn is impacted to prevent blockage. When the monitor 706 monitors that the water inside the filter box 701 is lower than the monitor 706, more water than the lack of water inside the filter box 701 will be injected, and then the empty fruits that are impacted and floated 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 the water pump is fixedly connected to a water storage tank, the drainage pipe 707 is fixedly connected to the water storage tank, one end of the water storage tank 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 an 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 for preliminary screening of the hawthorns. The filter holes of the two screening plates 702 are distributed from large to small, and the larger hawthorns and the smaller hawthorns can be preliminarily separated. 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, it will inject more water than the capacity of the filter box 701, 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 hawthorn falls 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 moves laterally and rotates with the conveyor belt 3, thereby realizing the transportation and rotation of the hawthorn.

[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 current two inflatable rollers 601 are marked with the label ring 611;

[0063] The air-filling roller 601 continues to move to one side of the air-injection tube 609. The induction block inside the air-injection tube 609 will identify the label ring 611, and use the magnetic block 607 to connect the air-filling roller 601 and the air-injection tube 609, accurately inject air into the corresponding air-injection tube 603, so that the air inside the air-filling roller 601 is filled, and the outer wall of the air-filling roller 601 is tightened, pushing the broken hawthorn to move up to the top surface of the air-filling roller 601, and then cooperating with the guide plate 610 to guide the broken hawthorn to move to one side so that it can be removed later;

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

[0065] Finally, the inflatable roller 601 without gas inside moves to the side of the reset tube 612, and the inflatable roller 601 and the reset tube 612 are connected by the magnetic block 607. The two air outlets of the reset tube 612 ensure that part of the gas is stably injected into the inflatable roller 601 to restore the inflatable roller 601 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 implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed in the present invention, which should be covered by the protection scope of the present invention.
