Description

Technical Field

[0001] The invention relates to the technical field of redistribution and transportation of day lilies, and in particular to a day lily production and processing device. Background Art

[0002] The drying equipment is used for drying daylilies. The drying equipment uses hot air to remove the moisture of daylilies to achieve drying. The drying process controls different drying temperatures at different stages and heats for a certain period of time under a specific stable condition. In order to quickly dissipate the moisture in the accumulated daylilies, a structure is also provided to turn the daylilies over.

[0003] When the day lily is sent to the conveyor belt drying device for drying, in order to improve the quality of the day lily after drying, a grid will be set to limit the position so that the day lily can be spread evenly and will not curl excessively during the drying process, so that the day lily can be more straight after drying;

[0004] However, the drying rates of the surface layer and the lower layer of the daylily spread on the conveyor belt are different. The daylilies in the lower layer are closely attached to each other, and the water loss efficiency of the daylilies in the lower layer is low. Therefore, it needs to be adjusted. The situation can be improved to a certain extent by evenly dropping the daylilies from the upper conveyor belt to the lower layer. However, it is not certain whether the daylilies in the lower layer can be redistributed by dropping. Therefore, it needs to be improved so that the daylilies in the lower layer can be actively distributed to the upper layer. Summary of the invention

[0005] The invention provides a day lily production and processing device, which solves the problem in the prior art that free falling cannot ensure that the day lilies in the lower layer can be fully distributed to the upper layer, reduces the low water loss efficiency of the day lilies in the lower layer, and reduces the drying quality.

The falling day lilies are selected by air through the exhaust device, so that the day lilies with lower degree of dryness enter the first cloth hopper on the left, and the day lilies with higher degree of dryness enter the second cloth hopper on the right. Subsequently, the day lilies with higher degree of dryness are spread on the lower plate chain conveyor first, and then the day lilies with lower degree of dryness are spread on the upper layer, so that the day lilies with lower degree of dryness can lose moisture faster on the upper layer, thereby improving the drying efficiency and uniformity of the day lilies and the drying quality. The exhaust device, the first cloth hopper, the second cloth hopper, the first cloth belt and the second cloth belt can actively re-spread the day lilies and evenly spread them on the lower plate chain conveyor.

[0008] As a further improvement of the above solution:

The lower hopper is located directly above the starting end of the feeding conveyor belt, and the end of the feeding conveyor belt extends into the feed port of the drying box, and the starting end of the plate chain conveyor device on the top layer extends into the feed port and is located directly below the feeding conveyor belt. After the day lily is manually fed into the lower hopper, it is evenly spread onto the feeding conveyor belt through the lower hopper, and then the day lily is automatically transported into the drying box for automatic drying through the feeding conveyor belt, with a high degree of automation.

[0010] Preferably, an air inlet is installed at the bottom of one side of the drying box, and an exhaust port is installed at the top of the drying box, so that the day lily can be fully dried by passing hot air into the drying box.

[0011] Preferably, the plate chain conveyor device forms a continuous coil-like air duct in the drying box, the air inlet is at the starting end of the coil-like air duct, and the exhaust port is located on the top side of the coil-like air duct. A continuous coil-like air duct is formed in the drying box, so that the introduced hot air can flow smoothly along the coil-like air duct, taking away the moisture of the day lily and improving the drying efficiency.

[0012] Preferably, the exhaust device is installed at the corner of the coil-shaped air duct, and the exhaust port of the exhaust device is adapted to the material height position on the upper part of the plate chain conveyor device. The exhaust device can further improve the smoothness of the circulation of hot air in the air duct and accelerate the loss of moisture in the day lily.

[0013] Preferably, the plate chain conveyor device is equipped with a material distribution grille device, which includes a strip opening opened on the conveyor belt, a retractable grille is arranged in the strip opening, and a U-shaped accommodating box is installed on the inner side of the plate chain conveyor device at the strip opening, and the grille is installed in the U-shaped accommodating box. The grille retracts when the unloading end is in a horizontal state, and extends again when it moves to a vertical state. By arranging the grille on the plate chain conveyor device, the day lily can be limited so that the day lily will not curl excessively during the drying process, thereby improving the drying quality of the day lily and making the day lily straighter after drying.

[0014] Preferably, a return spring is installed in the U-shaped accommodating box, and the other end of the return spring is connected to the grille, and support rods are installed at both ends of the grille. A guide rail is installed on the inner side of the plate chain conveyor at the unloading end, and the guide rail is fixedly connected to the main frame of the plate chain conveyor. The guide rail cooperates with the support rod so that the grille is recovered into the U-shaped accommodating box when it is in a horizontal state. When the grille moves to a vertical state, the guide rail no longer limits the support rod, and the grille extends out under the action of the return spring, so that the grille moves to the unloading end of the plate chain conveyor, and when it is in a horizontal state, the support rod connected to the grille The guide rails are in contact, and the distance between the guide rails and the plate chain conveyor belt gradually increases, so that the grille retracts into the U-shaped containing box, and the day lilies supported by the grille fall under the action of gravity, so that the falling of materials is concentrated in the vertical downward tangent direction of the unloading end of the plate chain conveyor device, and the day lilies with a lower degree of drying are basically on the side of the plate chain conveyor belt, and the day lilies with a higher degree of drying are basically on the side of the exhaust device, so that the day lilies with a higher degree of drying are affected by the wind force of the exhaust device, so that the day lilies with different degrees of drying can be separated and collected separately, thereby improving the effect of separate collection.

[0015] Preferably, an electromagnet, a return spring, a magnetic sheet and a grille are installed in the U-shaped containing box, the electromagnet is fixedly connected to the bottom of the U-shaped containing box, one end of the return spring is fixedly connected to the bottom of the U-shaped containing box, and the other end is fixedly connected to the magnetic sheet, the magnetic sheet is fixedly connected to the grille, and a first conductive electrode sheet and a second conductive electrode sheet are installed inside the plate chain conveying device at one end of the unloading material, the first conductive electrode sheet and the second conductive electrode sheet are fixedly connected to the main frame of the plate chain conveying device through an insulating bracket, and when the U-shaped containing box is moved to a horizontal position, the electromagnet is energized, and the grille The grille retracts quickly, and when the grille moves to a vertical state, the electromagnet is de-energized, and the grille is reset and extended under the action of a reset spring. Furthermore, when the electromagnet is energized, the grille can be retracted more quickly, so that the grille has less impact on the day lily during the retraction process, so that the day lily can be kept more completely during the falling process. The day lily with a lower degree of drying is close to the plate chain conveyor device, and the day lily with a higher degree of drying is close to the exhaust device, so that the exhaust device can easily send the day lily with a higher degree of drying into the second cloth hopper when applying wind force.

[0016] Preferably, a support frame is also installed inside the plate chain conveyor device, and the support frame is fixedly connected to the main frame of the plate chain conveyor device, and the outer surface of the support frame is in sliding contact with the U-shaped containing box. The support frame supports the U-shaped containing box, and the support frame and the U-shaped containing box can support the plate chain conveyor belt, so that the upper surface of the plate chain conveyor belt is smoother.

[0017] Preferably, axially extending edges are provided at both ends of the U-shaped containing box, and the axially extending edges are fixedly connected to the inner side of the belt body of the plate chain conveyor. By providing the axially extending edges, the stability of the fixation between the U-shaped containing box and the plate chain conveyor belt can be improved.

[0018] It is to be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the invention.

[0019] In the present invention, an exhaust device is provided to select the falling day lilies by air, so that the day lilies with a lower degree of drying enter the first distribution hopper on the left, and the day lilies with a higher degree of drying enter the second distribution hopper on the right. Subsequently, the day lilies with a higher degree of drying are first spread on the lower plate chain conveyor, and then the day lilies with a lower degree of drying are spread on the upper layer, so that the day lilies with a lower degree of drying can lose moisture faster on the upper layer, thereby improving the drying efficiency and uniformity of the day lilies and improving the drying quality. The exhaust device, the first distribution hopper, the second distribution hopper, the first distribution belt, and the second distribution belt can actively re-distribute and evenly spread the day lilies on the lower plate chain conveyor.

[0020] In the present invention, the grille is arranged on the plate chain conveyor device to limit the position of the day lily, so that the day lily will not curl excessively during the drying process, thereby improving the drying quality of the day lily and making the day lily straighter after drying.

[0021] In the present invention, when the grille moves to the unloading end of the plate chain conveyor and presents a horizontal state, the support rod connected to the grille contacts the guide rail, and the distance between the guide rail and the plate chain conveyor gradually increases, so that the grille retracts into the U-shaped containing box, so that the day lily supported by the grille falls under the action of gravity, so that the falling of materials is concentrated in the vertical downward tangent direction of the unloading end of the plate chain conveyor, and the day lily with a lower degree of drying is basically on the side of the plate chain conveyor, and the day lily with a higher degree of drying is basically on the side of the exhaust device, so that the day lily with a higher degree of drying is convenient to be affected by the wind force of the exhaust device, so that the day lilies with different degrees of drying are separated and collected separately, thereby improving the effect of separate collection.

[0022] In the present invention, further, when the electromagnet is energized, the grille can be retracted more quickly, so that the grille has less impact on the day lily during the retraction process, so that the day lily can be kept more completely in the process of falling, with the day lily with a lower degree of drying being close to the plate chain conveyor device, and the day lily with a higher degree of drying being close to the exhaust device, so that the exhaust device can easily deliver the day lily with a higher degree of drying into the second cloth hopper when applying wind force.

[0023] When the day lilies are transported in the drying box, the day lilies with a higher degree of drying and the day lilies with a lower degree of drying can be actively redistributed. The dried day lilies can also be directly sent out through the conveyor belt. The degree of automation is high and the continuous production capacity is strong. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Example 1, reference Figure 1A day lily production and processing equipment comprises a feeding device, a drying device and a discharging device. The feeding device comprises a frame 15, on which a lower hopper 1 and a feeding conveyor belt 2 are installed. The lower hopper 1 is located just above the lower end of the feeding conveyor belt. The day lily is manually fed into the lower hopper 1, and the day lily is evenly spread on the feeding conveyor belt 2 through the lower hopper 1. The upper end of the feeding conveyor belt extends into the feeding port 4 of the drying box 3, and the day lily is evenly spread on the plate chain conveyor device 6 through the feeding conveyor belt. The day lily is transported in the drying box 3. During the drying process, multiple plate chain conveying devices 6 are installed in the drying box 3, among which one end of the top plate chain conveying device 6 is located directly below the feeding conveyor belt, and the end of the bottom plate chain conveying device 6 extends into the discharge port 12 and is located directly above the discharge conveyor belt 13. The end of the upper plate chain conveying device 6 is located within the initial end range of the lower plate chain conveying device 6, thereby ensuring that the day lily conveyed by the upper plate chain conveying device 6 can smoothly fall onto the lower plate chain conveying device 6, and the uppermost plate chain conveying device 6 and the lowermost plate chain conveying device A plurality of intermediate plate chain conveying devices 6 are also arranged between the devices 6. Starting from the second plate chain conveying device 6 from the top to the bottom, each plate chain conveying device 6 is equipped with a separation and re-clothing device at the starting section, including an exhaust device 7 installed on one side, and a first heavy cloth hopper 8 on the inner side and a second heavy cloth hopper 9 on the outer side below. A first heavy cloth belt 10 for conveying inwards and a second heavy cloth belt 11 for conveying outwards are also installed below the first heavy cloth hopper 8 and the second heavy cloth hopper 9. The day lily in the first heavy cloth hopper 8 is evenly spread on the first heavy cloth hopper below. On the material belt 10, the day lilies in the second cloth hopper 9 are evenly spread in the second cloth belt 11 below. The day lilies evenly spread on the second cloth belt 11 are first evenly spread on the plate chain conveyor 6 below. Then, as the plate chain conveyor 6 moves toward the first cloth belt 10, the day lilies on the first cloth belt 10 are spread on the upper layer of the plate chain conveyor 6 below. The subsequent separation and redistribution device continues the above operation, so that the day lilies on the lower and upper layers will be redistributed every time the day lilies pass through a layer of the plate chain conveyor 6.

[0040] Example 2, reference Figure 1-Figure 3 as well as Figure 6 The plate chain conveyor 6 is driven to rotate by a driving sprocket 608. Each plate chain conveyor 6 is equipped with a material distribution grille 603 device. The plate chain conveyor 6 includes a plate chain conveyor belt 601. A strip opening 605 is opened on the plate chain conveyor belt 601. A retractable grille 603 is arranged in the strip opening 605. A U-shaped receiving box 606 is installed on the inner side of the plate chain conveyor belt 601 at the strip opening 605. The grille 603 is installed in the U-shaped receiving box 606. The grille 603 retracts when it moves to a horizontal state at one end of the material discharge, and re-extends when it moves to a vertical state.

[0041] A return spring 610 is installed in the U-shaped containing box 606, and the other end of the return spring 610 is connected to the grille 603. Support rods 607 are installed at both ends of the grille 603. A guide rail 604 is installed on the inner side of the unloading end of the plate chain conveyor 6. One side of the guide rail 604 is in contact with the inner side of the plate chain conveyor belt 601 to play a supporting role, and the other side of the guide rail 604 cooperates with the support rod 607 so that the grille 603 is recovered into the U-shaped containing box 606 when it is in a horizontal state. At this time, the return spring 610 is compressed. When the grille 603 moves to a vertical state, the guide rail 604 no longer limits the support rod 607, and the grille 603 extends out under the action of the return spring 610.

[0042] Example 3, reference Figure 1 as well as Figure 4-Figure 6 An electromagnet 611, a return spring 610, a magnetic sheet, and a grille 603 are installed in the U-shaped container box 606, wherein the electromagnet 611 is fixedly connected to the bottom of the U-shaped container box 606, one end of the return spring 610 is fixedly connected to the bottom of the U-shaped container box 606, and the other end is fixedly connected to the magnetic sheet, and the magnetic sheet is fixedly connected to the grille 603. A first conductive electrode sheet 612 and a second conductive electrode sheet 613 are installed at the unloading end of the plate chain conveyor 6, and the first conductive electrode sheet 612 and the second conductive electrode sheet 613 are fixedly connected to the main frame of the plate chain conveyor 6 through an insulating bracket. When the U-shaped container box 606 moves to a horizontal position, the U The first conductive end 614 on the type housing box 606 contacts the first conductive electrode sheet 612, and the second conductive end 615 contacts the second conductive electrode sheet 613. At this time, the electromagnet 611 is energized, the electromagnet 611 adsorbs the magnetic attraction sheet, the grille 603 retracts quickly, and the reset spring 610 is in a compressed state. When the grille 603 moves to a vertical state, the first conductive end 614 is separated from the first conductive electrode sheet 612, the second conductive end 615 is separated from the second conductive electrode sheet 613, the electromagnet 611 is powered off and loses its magnetic attraction force, there is no magnetic attraction between the electromagnet 611 and the magnetic attraction sheet, and the grille 603 is reset and extended under the action of the reset spring 610.

[0043] A support frame 602 is also installed inside the plate chain conveyor 6. The support frame 602 is fixedly connected to the main frame of the plate chain conveyor 6, and the outer surface of the support frame 602 is in sliding contact with the U-shaped containing box 606. The support frame 602 supports the U-shaped containing box 606. Axial extension edges 609 are provided at both ends of the U-shaped containing box 606. The axial extension edges 609 are fixedly connected to the inner side of the belt body of the plate chain conveyor 6.

[0044] The plate chain conveyor 6 forms a continuous coil-shaped air duct in the drying box 3, the air inlet 14 is located at the starting end of the coil-shaped air duct, and the exhaust port 5 is located at one side of the top of the coil-shaped air duct.

[0045] The exhaust device 7 is installed at the corner of the coil-shaped air duct, and the exhaust port of the exhaust device 7 is adapted to the material height position on the upper part of the plate chain conveyor 6.

[0046] The working principle of this application is:

[0047] The day lily to be processed is put into the lower hopper 1, and the lower hopper 1 evenly spreads the day lily onto the loading conveyor belt 2. The day lily is transported to the feeding port 4 of the high-position drying box 3 through the loading conveyor belt 2, and then the day lily is sent to the first plate chain conveyor device 6, and the day lily is transported and dried by the plate chain conveyor device 6.

[0048] A grille 603 is provided on the plate chain conveyor 6, and the day lily is limited by the grille 603 so that the day lily will be limited by the grille 603 during the drying process to prevent the day lily from curling excessively during the drying process. When the day lily is sent to the end of the plate chain conveyor 6, the grille 603 moves to a horizontal position and retracts. The day lily above the retracted grille 603 falls freely, and an exhaust port of the exhaust device 7 is provided on the outside of the falling path. The drier day lily on the upper layer is more likely to move toward the side of the exhaust device 7 under the action of suction, and the day lily with higher moisture on the lower layer is not easy to move toward the side of the exhaust device 7 under the action of suction. The exhaust port of the exhaust device 7 faces the upper layer of the plate chain conveyor 6 and is adapted to the paving height of the day lily. When the grille 603 runs to a horizontal direction, refer to Figure 6 It can be seen that the daylilies with higher moisture content that were originally in the lower layer are basically on the left side, and the daylilies that were originally in the upper layer and relatively dry are basically on the right side and close to the exhaust device 7. Therefore, when the daylilies fall from the end of the plate chain conveyor device 6, the retractable grille 603 and the exhaust device 7 can conveniently separate and collect the relatively wet and relatively dry daylilies. The relatively wet daylilies that were originally in the lower layer fall into the first-layer cloth hopper 8 at the lower part, and the relatively dry daylilies that were originally in the upper layer fall into the second-layer cloth hopper 9 at the lower part. Subsequently, the relatively wet daylilies are evenly spread on the first-layer cloth belt 10 at the lower part through the first-layer cloth hopper 8, and then spread on the second-layer cloth belt 10 through the second-layer cloth hopper 8. The feeding hopper 9 spreads the drier day lilies evenly on the second-weight feeding belt 11 at the bottom, and the first-weight feeding belt 10 has the same conveying direction as the lower chain conveyor 6, and the unloading end of the first-weight feeding belt 10 is far away from the starting end of the lower chain conveyor 6. The conveying direction of the second-weight feeding belt 11 is opposite to that of the lower chain conveyor 6, and the unloading end of the second-weight feeding belt 11 is close to the starting end of the lower chain conveyor 6. Therefore, the lower chain conveyor 6 will first spread a layer of drier day lilies, and then the first-weight feeding belt 10 will evenly spread the wetter day lilies on the upper part of the drier day lilies.

[0049] The day lilies can be differentiated and collected at the end of each layer, the drier day lilies can be spread on the lower layer, and the wetter day lilies can be spread on the upper layer, thereby improving the drying efficiency of the day lilies and improving the spreading uniformity of the day lilies.

[0050] The exhaust device 7 can accelerate the air duct circulation, form a continuous coil-shaped air duct, and improve the drying efficiency.

[0051] The falling position of the day lily can be controlled by the grille 603 and the mechanism for controlling the extension and retraction of the grille 603, and the falling position of the day lily is limited to the tangential direction of the end of the plate chain conveyor device 6, so that the originally wet day lily 16 in the lower layer is on the left, and the originally drier day lily 17 in the upper layer is on the right side close to the exhaust device 7, thereby improving the convenience and accuracy of separating the heavy cloth, further improving the spreading uniformity of the day lily, and improving the drying efficiency and quality of the day lily.

[0052] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention; the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
