DETAILED DESCRIPTION

[0029] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings and specific implementation methods of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. 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.

[0030] like Figure 1 , Figure 2 The illustrated device is a highly efficient chrysanthemum picking device for preventing missed picking, comprising a trolley 1, a swinging assembly 2 and a combing assembly 3, wherein the swinging assembly 2 is mounted on the trolley 1, the combing assembly 3 is connected to the trolley 1 through the swinging assembly 2, and the swinging assembly 2 drives the combing assembly 3 to swing back and forth perpendicular to the traveling direction of the trolley 1. There are two groups of combing assemblies 3, which are stacked up and down, and the combing assemblies 3 on the upper layer protrude from the combing assemblies 3 on the lower layer along the traveling direction of the trolley 1.

[0031] When in use, the walking trolley 1 moves along the chrysanthemum ridge, driving the comb assembly 3 to move along the chrysanthemum. Under the action of the swing mechanism 2, the comb assembly 3 swings back and forth perpendicular to the forward direction, so that the chrysanthemum quickly enters the gap of the comb assembly 3 to avoid pushing down the chrysanthemum in front. At the same time, the two-layer comb assembly 3 can pick chrysanthemums of different heights, and the comb assembly 3 of the lower layer can pick chrysanthemums in a lodging state, reducing the missed picking of chrysanthemums.

[0032] like Figure 1 , Figure 4 As shown, the walking trolley 1 includes a frame 11, which is a rectangular frame welded from pipes. Four legs 12 are vertically installed at the four corners of the lower end surface of the frame 11. A walking wheel 13 is installed at the lower end of each leg 12. The walking wheel 13 has a hub motor to achieve independent control of each walking wheel 13. The two legs 12 located on one side of the traveling direction of the walking trolley 1 are connected to the walking wheel 13 through a steering mechanism 14, which is used to adjust the traveling direction of the walking trolley 1. The structure and principle of the walking trolley 11 are all existing technologies and will not be repeated here.

[0033] like Figure 1 , Figure 3 , Figure 4As shown, the swing assembly 2 includes a swing bracket 21 and a reciprocating drive mechanism 22. Two horizontal guide rails 23 are installed in parallel on the lower surface of the frame 11 of the traveling trolley 1. The horizontal guide rails 23 are arranged perpendicular to the traveling direction of the traveling trolley 1. The swing bracket 21 is a "door"-shaped structural frame. The upper end surface of the swing bracket 21 is connected to the horizontal guide rail 23 through a slider. The reciprocating drive mechanism 22 is installed between the frame 11 and the swing bracket 21, and is used to drive the swing bracket 21 to swing back and forth along the horizontal guide rail 23. Among them, the reciprocating drive mechanism 22 can be a cylinder, an oil cylinder or an electric telescopic rod, or a structure composed of a motor and a cam, a crank or other mechanical structure that can realize reciprocating linear motion, as long as the reciprocating linear motion of the swing bracket 21 and the frame 11 can be realized.

[0034] like Figure 5-Figure 7 As shown, the comb assembly 3 includes a comb bracket 31, comb teeth 32, a blade 33, a stopper 34, a roller brush 35, a blade holder 36 and a collection box 37. The comb bracket 31 is an H-shaped structure, and a comb seat 311 is horizontally mounted on the comb bracket 31, and a plurality of comb teeth 32 are arranged in a straight line on the comb seat 311.

[0035] like Figure 6 , Fig. 9 As shown, the comb teeth 32 include a connecting seat 321, a comb tooth body 322 and an arc-shaped portion 323. The end of the connecting seat 321 is fixed with an insert block that matches the comb tooth seat 311, and is locked with the comb tooth seat 311 by bolts, so that the comb teeth 32 can be quickly positioned and disassembled, and the damaged comb teeth 32 can be replaced conveniently. The comb tooth body 322 is fixed at one end of the connecting seat 321 at a downward inclination of 3-6°. The cross section of the comb tooth body 322 is T-shaped, and the cross section size of the comb tooth body 322 gradually decreases along the traveling direction of the walking trolley 1. On the one hand, the T-shaped structure can increase the structural strength of the comb tooth body 321 and avoid deformation of the comb tooth body 322; on the other hand, it can also reduce the thickness of the comb tooth body 322 in the vertical direction to avoid clogging of the comb tooth body 322. The gradual cross section makes the gap between adjacent comb teeth 32 appear to be larger on the outside and smaller on the inside, so as to adapt to the picking operation of chrysanthemums of different plant diameters. The arc portion 323 is fixed to one end of the comb body 322 away from the connecting seat 321 . The arc portion 323 is used to separate adjacent chrysanthemums, so as to facilitate the chrysanthemums to be dispersed into the gaps between different comb teeth 32 .

[0036] like Figure 5-Figure 8As shown, a tool holder 36 is installed at both ends of the comb tooth seat 311, and a plurality of adjustment holes 361 are provided on the tool holder 36. The adjustment holes 361 are threaded holes, and the plurality of adjustment holes 361 are evenly distributed along the length direction of the tool holder 36. A slotted hole 331 is provided at both ends of the blade 33, and a bolt is passed through the slotted hole 331 and screwed to the adjustment hole 361, and the blade 33 is installed between the two tool holders 36, and the cutting edge of the blade 33 faces the end of the comb teeth 32, and the blade 33 fits the upper end surface of the comb teeth 32. When the chrysanthemum moves to the blade 33 along the gap between the comb teeth 32, the blade 33 cuts the chrysanthemum from the receptacle. The blade 33 is connected to different adjustment holes 361, so that the position of the blade 33 on the comb teeth 32 can be adjusted, thereby changing the size of the gap at the blade 33, and cutting chrysanthemums of different plant diameters can be achieved. Among them, the blocking rod 34 is installed on the right side of the blade 33, that is, close to the end of the comb teeth 32, and the distance between the blocking rod 34 and the upper surface of the comb teeth 32 is greater than the size of the chrysanthemum flower. When the flower is higher than the blocking rod 34, the blocking rod 34 blocks the branches of the chrysanthemum, causing the chrysanthemum to tilt to the right, and will not move to the blade 33 until the chrysanthemum flower is lower than the blocking rod 34, thereby avoiding the chrysanthemum from having longer branches and stems, thereby improving the quality of the chrysanthemum.

[0037] like Figure 5-Figure 7 As shown, a collection box 37 is installed on the left side of the comb tooth bracket 31, and an opening is opened on the right side of the collection box 37, the opening faces the direction of the comb teeth 32, and the lower end surface of the opening is flush with the upper end surface of the comb tooth bracket 311. Adjustment brackets 312 are symmetrically installed on both sides of the comb tooth bracket 31, and the adjustment brackets 312 face the traveling direction of the walking trolley 1 and are parallel to the comb teeth 32. The adjustment brackets 312 are equipped with adjustment pieces 313, and the roller brush 35 is rotatably installed between the two adjustment pieces 313. A roller brush motor 351 is installed on any adjustment piece 313, and the output shaft of the roller brush motor 351 is connected to the roller brush 35 to drive the roller brush 35 to rotate. When in use, the position of the adjustment piece 313 is adjusted so that the roller brush 35 is located above the blade 33, so that the cut chrysanthemums are swept into the collection box 37. The collection box 37 can also be installed with a pipeline, and the chrysanthemums in the collection box 37 are transported to a larger box for concentration by using negative pressure.

[0038] like Figure 5-Figure 7As shown, a connecting bracket 38 is installed on the left side of the comb tooth bracket 31, and the connecting bracket 38 is fixedly connected to the swing bracket 21. A vertical guide rail 381 is installed on the right side of the connecting bracket 38, and the comb tooth bracket 31 is slidably connected to the vertical guide rail 381 through a slider. A lifting drive 39 is installed between the connecting bracket 38 and the comb tooth bracket 31, and the lifting drive 39 drives the comb tooth bracket 31 to move up and down along the vertical guide rail 381, thereby changing the height of the comb tooth assembly 3. Among them, the lifting drive 39 is a screw rod, the upper end of the screw rod is rotatably connected to the comb tooth bracket 31 through a bearing, the middle part of the screw rod is screwed to the connecting bracket 38, and a hand wheel is installed at the bottom of the screw rod. The position of the comb tooth assembly 3 can be adjusted by turning the hand wheel. The lifting drive 39 can also be a cylinder, a hydraulic cylinder or an electric telescopic rod.

[0039] The working method of the embodiment of the present application is:

[0040] First, adjust the heights of the two comb tooth assemblies according to the type of chrysanthemum, so that the upper comb tooth assembly is located in the middle of the height of the chrysanthemum, and the lower comb tooth assembly is lower than the height of the lowest chrysanthemum;

[0041] Then, adjust the position of the blade so that the gap between the teeth of the blade is slightly larger than the diameter of the chrysanthemum branch;

[0042] Finally, start the walking trolley and the swing assembly to make the comb tooth assembly swing forward along the chrysanthemum ridge.

[0043] During the picking process, the arc-shaped part at the front end of the comb teeth separates the chrysanthemums to both sides, and quickly enters the gap between the comb teeth under the action of swinging, reducing the number of chrysanthemums that the front end of the comb teeth touches, and preventing the chrysanthemums from falling forward and being missed. Fig.10 As shown, after the chrysanthemum 4 enters the gap between the comb teeth, as the walking trolley moves forward, the chrysanthemum 4 gradually approaches and contacts the blocking rod, and the blocking rod pushes the chrysanthemum 4 forward and tilts it, so that the flower 41 of the chrysanthemum 4 gradually approaches the blocking rod, and finally passes through the bottom of the blocking rod and contacts the blade, and the blade cuts the flower 41 from the receptacle of the flower 41, and the roller brush sweeps it into the collection box, completing the picking of the flower 41. Even if some chrysanthemums are pressed to the lower side of the upper comb tooth assembly, they will be picked by the lower comb tooth assembly, thereby reducing the missed picking of chrysanthemums.

[0044] The technical solution provided in the embodiments of the present application has at least the following technical effects or advantages:

[0045] 1. The swing assembly drives the comb teeth assembly to swing, so that the stems of the chrysanthemums can enter between the comb teeth as soon as possible, avoiding pushing the front chrysanthemums to fall down and press under the comb teeth. Through two groups of comb teeth assemblies staggered front and back, chrysanthemums of different heights can be picked, thereby reducing the missed picking of chrysanthemums;

[0046] 2. The chrysanthemums pulled into the gap of the comb teeth are cut off by the blade, avoiding damage to the chrysanthemums by pulling them off, and reducing the length of the stems after picking, thereby improving the harvest quality;

[0047] 3. By adjusting the height of the comb tooth assembly and the position of the blade on the comb teeth, different varieties of chrysanthemums can be picked, thereby increasing the application range of the picking device.
