Description

Technical Field

[0001] This invention relates to the field of pea shoot harvesting technology, specifically a pea shoot harvesting component and its usage method. Background Technology

[0002] Commercial pea shoot cultivation often uses hydroponics, where peas are placed in a tray, and once the pea shoots have grown, they are cut off at the base before being packaged and sold. Harvesting pea shoots by hand with scissors presents the following problems: (1) It is inefficient to hold the pea shoot with one hand and the scissors with the other; (2) The pea shoots are not neatly arranged after harvesting, and they need to be rearranged neatly during the packaging process. Summary of the Invention

[0003] The purpose of this invention is to provide a pea shoot harvesting component and its usage method, which solves the problems of low harvesting efficiency and uneven arrangement of pea shoots after harvesting when using existing handheld scissors.

[0004] The technical solution adopted by this invention to solve its technical problem is: a pea shoot harvesting assembly, including a matching sorting and cutting device and a bundling device. The sorting and cutting device includes a frame, a sorting unit, and a cutting unit. The frame has a "U"-shaped structure. During use, the frame is moved so that the pea shoot tray enters the inner side of the frame from the opening. The sorting unit includes a first lever, a second lever, and a sorting drive mechanism. Both the first and second levers have two parts, with the two first levers located between the two second levers. The first levers cooperate with the corresponding second levers to clamp the pea shoots located between them. The sorting drive mechanism is mounted on the frame to drive the cooperating first levers. The first lever and the second lever move closer to or further apart from each other. When the first lever moves, it divides the pea shoots into two pieces longitudinally. The cutting unit includes a cutting chain support, a cutting chain, a cutting motor, and a transverse drive mechanism. The cutting chain support is slidably connected to the frame and moves laterally under the drive of the transverse drive mechanism. The cutting chain is located on the cutting chain support and below the first lever. The cutting chain moves under the drive of the cutting motor located on the cutting chain support. The binding device includes a first clamp with one open side and a second clamp with one open side. In use, the upper part of the pea shoot is placed between the first clamp and the second clamp, so that the open end of the first clamp is snapped together with the open end of the second clamp.

[0005] Furthermore, the dispensing drive mechanism includes a housing, a dispensing motor, and a dispensing screw. The housing is fixed on the frame, the dispensing screw is longitudinally arranged and rotatably installed in the housing, and the dispensing motor is fixed at one end of the housing to drive the rotation of the dispensing screw. The outer wall of the dispensing screw is provided with four external threads along the axial direction. Two external threads spaced apart in the middle of the four external threads have the same direction of rotation, and two adjacent external threads have opposite directions of rotation. One end of the first lever engages with the middle external thread, and one end of the second lever engages with the external threads at both ends.

[0006] Furthermore, one end of the first lever and the second lever has a lever nut that engages with an external thread.

[0007] Furthermore, the two parallel sections arranged on the frame are mounting arms, and the bottom of each end of the mounting arm has rollers.

[0008] Furthermore, it also includes a sealing rod located at the opening of the frame, one end of which is hinged to one of the mounting arms, and the other end of which is magnetically engaged with another mounting arm.

[0009] Furthermore, the top of the sealing rod has a guide rod, and after the other end of the sealing rod is attracted to the corresponding mounting arm, the other end of the first lever and the other end of the second lever contact the side of the guide rod and are slidably connected.

[0010] Furthermore, the cutting chain bracket includes a mounting base and a connecting rod. Each mounting arm has a mounting base slidably mounted on it, and the connecting rod is located between two mounting bases and connected to the two mounting bases to form a whole.

[0011] Furthermore, the transverse drive mechanism includes a transverse motor, a transverse lead screw, and a mounting nut. The transverse lead screw is rotatably mounted in one of the mounting arms. The transverse motor is fixed on the frame to drive the transverse lead screw to rotate. The mounting nut is fixed on one of the mounting seats and threadedly connected to the transverse lead screw.

[0012] Furthermore, the inner side of the second clamp has a flexible, dense block, which works in conjunction with the first clamp to clamp the upper part of the pea seedling.

[0013] The present invention also provides a method for using a pea shoot harvesting component, comprising the following steps:

[0014] S1. Place the tray for hydroponic pea seedling cultivation inside the frame, and make the first lever pass through the pea seedling to divide the pea seedling into two pieces along the longitudinal direction, with the pea seedling located between the two second levers.

[0015] S2. The first lever and the second lever are moved by the distribution drive mechanism, so that the first lever and the corresponding second lever work together to gather the pea seedlings.

[0016] S3. The upper part of the pea seedlings is tied up using the tying device;

[0017] S4. The pea seedling roots are cut by the lateral movement of the cutting unit.

[0018] The beneficial effects of this invention are as follows: By setting up a sorting and cutting device, the peas on the pea sprout tray are sorted into two pieces, and then the pea sprouts in each piece are gathered together. Subsequently, the upper part of the gathered pea sprouts is tied together by a binding device, and finally the roots of the pea sprouts are cut by a cutting unit, thereby realizing the harvesting of pea sprouts. Under the action of the binding device, the harvested pea sprouts are arranged more neatly, and the harvesting efficiency is relatively high. Attached Figure Description

[0037] like Figures 1 to 17 As shown, the pea shoot harvesting assembly of the present invention includes a sorting and cutting device and a binding device 8. The sorting and cutting device includes a frame 1, a sorting unit and a cutting unit. The binding device 8 includes a first clamp 81 and a second clamp 82. The present invention will be described in detail below with reference to the accompanying drawings.

[0038] like Figures 1 to 17 As shown, the pea shoot harvesting assembly of the present invention includes a matching splitting and cutting device and a bundling device 8, such as... Figures 1 to 10 As shown, the sorting and cutting device includes a frame 1, a sorting unit, and a cutting unit. The frame 1 has a U-shaped structure, with two parallel mounting arms 11 on it. Rollers 12 are located at the bottom of both ends of the mounting arms 11, facilitating the movement of the entire frame 1. The structure of the frame 1 creates an opening, allowing the pea shoot tray to enter the inner side of the frame 1 through this opening during use. To facilitate the movement of the frame 1, as shown... Figure 5 , Figure 6As shown, a mounting plate 14 is provided on the frame 1 between the two mounting arms 11, and a handle 15 is provided on the mounting plate 14. After holding the handle 15, the frame 1 is moved.

[0039] like Figures 1 to 3 As shown, the sorting unit includes a first lever 2, a second lever 2', and a sorting drive mechanism. Each of the first levers 2 and the second levers 2' has two parts, with the two first levers 2 located between the two second levers 2'. The first levers 2 cooperate with the corresponding second levers 2' to gather and hold the pea seedlings located between them. The sorting drive mechanism, mounted on the frame 1, drives the cooperating first levers 2 and second levers 2' to move closer or further apart. When the first levers 2 move, they sort the pea seedlings longitudinally into two pieces. Specifically, as... Figure 1 , Figure 3 and Figure 9 As shown, the dispensing drive mechanism includes a housing 5, a dispensing motor 51, and a dispensing screw 53. The housing 5 is a rectangular structure and is fixed on the frame 1. A mounting groove 52 is provided on the side of the housing 5. The dispensing screw 53 is longitudinally arranged and rotatably mounted in the mounting groove 52 of the housing 5. The dispensing motor 51 is fixed to one end of the housing 5 to drive the rotation of the dispensing screw 53. The outer wall of the dispensing screw 53 has four external threads 54 arranged axially. Two external threads 54 spaced apart in the middle have the same direction of rotation, while two adjacent external threads 54 have opposite directions of rotation. One end of the first lever 2 engages with the middle external thread 54, and one end of the second lever 2' engages with the external threads 54 at both ends. To achieve threaded assembly, as shown... Figure 10 As shown, one end of the first lever 2 has a lever nut 21 that mates with the external thread 54. Similarly, one end of the second lever 2' also has a lever nut 21 that mates with the external thread 54. After the shifting drive mechanism is activated, the rotation of the shifting screw 53 drives the movement of the lever nut 21, which in turn drives the movement of the first lever 2 and the second lever 2'.

[0040] To guide the movement of the first lever 2 and the second lever 2', such as Figure 1 , Figure 2 As shown, a side baffle 4 is fixed to the top of the frame 1. The side baffle 4 has a downward-facing "]" shaped structure. One end of the first lever 2 and the second lever 2' is located between the side baffle 4 and the frame 1 and is slidably connected to the side baffle 4. The side baffle 4 also acts as a barrier to the pea seedlings. To further guide the movement of the first lever 2 and the second lever 2', as shown... Figures 1 to 3 As shown, it also includes a sealing rod 3 located at the opening of the frame 1. One end of the sealing rod 3 is hinged to one section of the mounting arm 11, and the other end of the sealing rod 3 is magnetically engaged with another section of the mounting arm 11. Figure 2As shown, one end of the mounting arm 11 has a notch 17. One end of the sealing rod 3 extends into the notch 17 of one section of the mounting arm 11 and is hinged to that section. The other end of the sealing rod 3 has an iron plate, and the notch 17 of the other section of the mounting arm 11 has a magnet. After the other end of the sealing rod 3 extends into the notch 17 of the other section of the mounting arm 11 and contacts the magnet, the other end of the sealing rod 3 is magnetically attracted to the mounting arm 11. The top of the sealing rod 3 has a guide rod 31. After the other end of the sealing rod 3 is attracted to the corresponding mounting arm 11, the other ends of the first lever 2 and the second lever 2' contact the side of the guide rod 31 and slide, thereby providing further guidance for the movement of the first lever 2 and the second lever 2'. To facilitate the contact between the first lever 2 and the second lever 2' and the guide rod 31 after the first lever 2 and the second lever 2' start to move, rounded corners 32 are provided at both ends of the guide rod 31. The other ends of the first lever 2 and the second lever 2' move past the rounded corners 32 and then move to contact the side of the guide rod 31.

[0041] like Figure 3 , Figure 7 and Figure 8 As shown, the cutting unit includes a cutting chain support 6, a cutting chain 65, a cutting motor 67, and a lateral drive mechanism. The cutting chain support 6 is slidably connected to the frame 1 and moves laterally under the drive of the lateral drive mechanism. The cutting chain 65 is located on the cutting chain support 6 and below the first lever 2. The cutting chain 65 moves under the drive of the cutting motor 67 located on the cutting chain support 6. Specifically, as... Figure 3 As shown, the cutting chain bracket 6 includes a mounting base 61 and a connecting rod 62. A mounting base 61 is slidably mounted on each mounting arm 11, and the connecting rod 62 is located between two mounting bases 61 and connected to them as a whole. Figure 8 As shown, the side wall of the mounting base 61 has a protrusion 66 for fixed connection with the connecting rod 62. The lateral drive mechanism includes a lateral motor 7, a lateral lead screw 72, and a mounting base nut 63. The lateral lead screw 72 is rotatably mounted in one section of the mounting arm 11 via a bearing 73. The lateral motor 7 is fixed to the mounting plate 14 to drive the rotation of the lateral lead screw 72, as shown. Figure 8As shown, the output shaft of the transverse motor 7 is fixedly connected to the transverse lead screw 72 via a coupling 71. The mounting nut 63 is fixed to one of the mounting seats 61 and threadedly connected to the transverse lead screw 72. When the transverse motor 7 is started, the transverse lead screw 72 rotates, thereby moving the mounting nut 63 and consequently the cutting chain support 6. A rotating wheel 64 is rotatably mounted on the mounting seat 61, and the cutting chain 65 is located between the two rotating wheels 64. The cutting motor 67 directly drives the rotation of one of the rotating wheels 64, thereby moving the cutting chain 65. To avoid obstructing the mounting nut 63, a long groove 13 is provided on the side wall of one section of the mounting arm 11. The mounting nut 63 passes through this long groove 13 and is slidably connected to it. A slider 68 is provided on the other mounting seat 61, and a sliding groove 16 is provided on the other section of the mounting arm 11. The slider 68 is slidably mounted within this sliding groove 16.

[0042] like Figures 1 to 13 As shown, the binding device 8 includes a first clamp 81 with one open side and a second clamp 82 with one open side. Both the first clamp 81 and the second clamp 82 have a "U"-shaped structure. The outer wall of the open end of the first clamp 81 is provided with a limiting strip 83, and the inner wall of the open end of the second clamp 82 is provided with a limiting groove. In use, the upper part of the pea seedling is placed inside the first clamp 81, and then the first clamp 81 is pinched to retract its open end. Then, the open end of the first clamp 81 is inserted into the open end of the second clamp 82 until the limiting strip 83 is inserted into the limiting groove. At this time, the first clamp 81 and the second clamp 82 are fastened together, and the first clamp 81 and the second clamp 82 work together to bind the upper part of the pea seedling. To ensure the clamping force on the upper part of the pea seedling, there is a flexible dense block 84 on the inner side of the second clamp 82. The dense block 84 works with the first clamp 81 to clamp the upper part of the pea seedling. To increase friction, reduce weight, and ensure structural strength, the side wall of the second clamp 82 is provided with a groove 85. In use, the upper part of the pea shoot is placed between the first clamp 81 and the second clamp 82, causing the open end of the first clamp 81 to snap into place with the open end of the second clamp 82. When the first clamp 81 and the second clamp 82 are of different sizes, a fixed amount of pea shoots can be bundled together using the first clamp 81 and the second clamp 82.

[0043] The following describes how to use the pea shoot harvesting component, including the following steps:

[0044] S1, such as Figure 14 As shown, the folding sealing rod 3 opens the opening of the frame 1, and the tray for hydroponic pea seedlings 9 is placed inside the frame 1, so that the first lever 2 passes through the pea seedling and divides the pea seedling into two pieces along the longitudinal direction, and the pea seedling is located between the two second levers 2'.

[0045] S2, such as Figure 15As shown, the reverse folding of the sealing rod 3 causes it to seal the opening of the frame 1, as... Figure 16 As shown, the first lever 2 and the second lever 2' are moved by the distribution drive mechanism, so that the first lever 2 and the corresponding second lever 2' work together to gather the pea seedlings.

[0046] S3, such as Figure 17 As shown, the upper part of the pea seedlings is tied up by the tying device 8; at this time, the tying device 8 contains a fixed amount of pea seedlings.

[0047] S4. The pea shoot roots are cut by the lateral movement of the cutting unit, which not only harvests the pea shoots but also keeps them neat.

[0048] This invention uses a sorting and cutting device to divide peas on a pea sprout tray into two pieces, then gathers the pea sprouts from each piece together to facilitate the division. Next, a binding device binds the upper part of the gathered pea sprouts, and finally, a cutting unit cuts the roots of the pea sprouts to harvest them. Thanks to the binding device, the harvested pea sprouts are arranged neatly, and the harvesting efficiency is relatively high.
