DETAILED DESCRIPTION

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation modes.

[0018] like Figure 1 As shown, this embodiment provides a seedling planting spraying device, including a planting spraying frame 1, a conveying mechanism 2 arranged on the planting spraying frame, and a planting mechanism 3 and a spraying mechanism 4 arranged on the planting spraying frame 1 in sequence along the conveying direction of the conveying mechanism 2. This device transports the seedling bag (seedling cup) filled with the matrix along the conveying mechanism, passes through the planting mechanism 3 and the spraying mechanism 4 in sequence, so as to plant the seedlings in the seedling bag (seedling cup), and spray them, so as to realize the automation of the seedling planting spraying work. The specific structure and working principle of each mechanism are introduced in detail below.

[0019] like Figure 2 As shown, the conveying mechanism 2 mainly adopts a belt conveyor, and a plurality of partition plates 22 are evenly arranged on the conveyor belt 21 of the belt conveyor along its conveying direction. A seedling bag (seedling cup) can be placed between adjacent partition plates 22 to ensure the distance stability between adjacent seedling bags (seedling cups) to avoid mutual influence; especially for seedling bags with insufficient structure, the partition plates 22 can also effectively maintain the upright state of the seedling bags to prevent tipping.

[0020] In order to ensure that the seedling bag (seedling cup) can accurately cooperate with the planting mechanism 3 and the spraying mechanism 4, the planting spraying frame 1 is provided with a blocking rod 11 on both sides of the opposite sides, and the blocking rod 11 extends above the conveyor belt 21 to limit the left and right positions of the seedling bag (seedling cup), thereby ensuring that the center position of the seedling bag (seedling cup) can be aligned with the output end of the planting mechanism 3 and the spraying mechanism 4, and the quality of the planting spraying is guaranteed. Correspondingly, the two blocking rods 11 also play a certain role in maintaining the upright state of the seedling bag. In order to facilitate the adjustment of the position of the baffle rod 11, an adjustment component is provided between the baffle rod 11 and the planting spray rack 1, including a connecting rod 12 and a connecting plate 13. The connecting plate 13 is fixedly connected to the baffle rod 11, and the two ends of the connecting rod 12 are rotatably connected to the connecting plate 13 and the planting spray rack 1 respectively, so that the distance that the baffle rod 11 extends to the middle of the conveyor belt 21 can be adjusted by rotating the connecting rod 12, so as to provide a limiting effect while avoiding affecting the normal transportation of the seedling bag (seedling cup).

[0021] Since the conveyor belt 21 is provided with a partition plate 22, it is not convenient to receive the seedling bag (seedling cup) from the horizontal direction, or in order to cooperate with the top-down feeding direction of the filling equipment, the present device adopts the method of receiving the seedling bag (seedling cup) from the top-down. If the seedling bag (seedling cup) is allowed to fall from the top, it is bound to cause the seedling matrix to splash. For this reason, the feeding end of the transplanting spraying frame 1 is provided with a material receiving mechanism 5, and the material receiving mechanism 5 includes a material receiving lifting cylinder 51 arranged upward at the output end, and a material receiving plate 52 arranged at the output end of the material receiving lifting cylinder 51, and a partition plate avoidance port 521 is provided on the material receiving plate 52. When working, the material receiving lifting cylinder 51 first lifts the material receiving plate 52 to stably receive a seedling bag (seedling cup). At this time, the conveyor belt 21 below moves forward one position. Since the material receiving plate 52 is suspended, it will not interfere with the partition plate 22; then the material receiving plate 52 is reset downward, and the two partition plates on the conveyor belt 21 pass through the partition plate avoidance opening 521 on the material receiving plate 52, and are respectively located at the front and rear sides of the seedling bag (seedling cup); then the conveyor belt 21 continues to move forward one position, and the seedling bag (seedling cup) is pushed out of the material receiving plate 52 to the conveyor belt 21 by the partition plate 22, and then the material receiving plate 52 is lifted again to receive the next seedling bag (seedling cup), and then the conveyor belt 21 moves forward one position again, and the next partition plate 22 is transferred to the bottom of the material receiving plate 52; repeating the above actions can realize the orderly reception of the seedling bag (seedling cup) from top to bottom, and avoid the problem of seedling matrix splashing caused by the seedling bag (seedling cup) falling from a high place. In addition, in order to reduce the supporting pressure of the material receiving lifting cylinder 51 , a plurality of material receiving plate weight reduction holes 522 are provided on the material receiving plate 52 .

[0022] like Figure 3As shown, the planting mechanism 3 includes a planting lifting assembly, a seedling planting assembly arranged at the lifting end of the planting lifting assembly, and the seedling planting assembly includes two semi-conical buckets 31 and a seedling planting driving structure for driving the two semi-conical buckets 31 to open and close each other. The overall working principle of the planting mechanism is: the seedlings are placed in the conical bucket formed by the two semi-conical buckets 31 fitting together, and the tip of the conical bucket is used to insert downward into the matrix of the seedling bag (seedling cup) under the drive of the lifting assembly, and then the two semi-conical buckets 31 are separated and reset upward, and the seedlings are left in the matrix, completing the seedling planting action.

[0023] Due to the structure of the semi-conical bucket 31 being thick at the top and thin at the bottom, if the seedlings are planted in a manner of separating the two semi-conical buckets horizontally, when the thinner lower end is separated to a width sufficient for the release of the seedlings, the thicker upper part will prop up a larger hole in the matrix, and the planted seedlings are prone to tilt or fall over. For this reason, the seedling planting assembly includes a seedling planting frame 32, and the thicker ends of the two semi-conical buckets 31 are rotatably connected to the seedling planting frame 32, and the seedling planting drive structure drives the two semi-conical buckets 31 to rotate so that the thinner ends of the two semi-conical buckets 31 open and close with each other. Thus, by rotating the semi-conical bucket 31 around its upper end, the separation amplitude of its lower end is greater than that of the upper end, so that when the seedlings are released, the width of the thicker upper part is equivalent to that of the lower end, ensuring that the seedlings are smoothly planted into the matrix while avoiding leaving too large holes in the matrix, thereby ensuring the quality of the seedlings.

[0024] Specifically, the seedling planting drive structure includes two seedling planting cylinders 33 that drive a semi-conical bucket 31 respectively. The two ends of the seedling planting cylinder 33 are respectively connected to the seedling planting frame 32 and the semi-conical bucket 31 for rotation, that is, the semi-conical bucket 31 is driven by the seedling planting cylinder 33 to achieve rotation, and the action is stable and efficient. In order to facilitate the rotation connection between the seedling planting cylinder 33 and the semi-conical bucket 31, a driving block 34 is provided on the outer surface of the thicker end of the semi-conical bucket 31, and the driving block 34 is connected to the seedling planting frame 32 for rotation. A driving arm 35 is provided on the driving block 34, and the driving arm 35 is connected to the seedling planting cylinder 33 for rotation, wherein the driving block 34 increases the thickness of the semi-conical bucket 31, so as to facilitate the setting of the rotating shaft and the seedling planting frame 32 for rotation connection, and avoid passing the rotating shaft through the semi-conical bucket 31 to affect its internal space; the driving arm 35 extends the force arm of the seedling planting cylinder 33 for the driving force of the semi-conical bucket 31, thereby increasing the force of the semi-conical bucket 31 to open the substrate, and ensuring the stability and efficiency of the seedling planting action.

[0025] In addition, in order to limit the opening range of the two semi-conical buckets 31, a limiting chamfer 311 may be provided at the upper end of one of the semi-conical buckets. When the straight edge of the other semi-conical bucket fits with the limiting chamfer, the maximum opening angle of the two semi-conical buckets 31 is reached. Since the side wall of the semi-conical bucket 31 is relatively thin, the abutment stability when the straight edge fits with the limiting chamfer may be insufficient. Therefore, one of the driving blocks 34 is also provided with a limiting chamfer, which effectively increases the contact area of ​​the two surfaces that are mutually abutting and limiting, and ensures the stability of the limiting effect.

[0026] Since the semi-conical bucket 31 and the seedling driving structure generally need to be arranged inside the seedling frame 32 to ensure safety, a seedling placing hopper 36 is provided above the two semi-conical buckets 31 on the seedling frame 32, and the seedlings can be sent into the two semi-conical buckets 31 through the seedling placing hopper 36.

[0027] The planting lifting assembly includes a planting mounting frame 37, a planting lifting cylinder 38 disposed between the planting mounting frame 37 and the seedling planting frame 32, and a planting lifting guide rod 39 to achieve a stable lifting action.

[0028] like Figure 4 As shown, the spray mechanism 4 includes a spray box 41, a spray head 42 arranged in the spray box 41, and a water supply pipe connected to the spray head 42. The spray box 41 is opened at the front and rear and spans across the planting spray machine frame 1. The conveyor belt 21 carries the seedling bag (seedling cup) through the spray box 41. The spray head 42 sprays an appropriate amount of water into the seedling bag (seedling cup), which not only provides moisture for the seedlings, but also increases the compactness of the matrix around the seedlings to prevent the seedlings from tilting.

[0029] In addition, in order to ensure the accuracy of the cooperation between the planting mechanism 3 and the spraying mechanism 4 and the seedling bag (seedling cup), photoelectric sensors are provided at the planting mechanism 3 and the spraying mechanism 4 to accurately obtain the position of the seedling bag (seedling cup). Among them, the planting photoelectric sensor 301 at the planting mechanism 3 can be set at a position corresponding to the lower end of the semi-conical bucket 31, so that when the seedling bag (seedling cup) is identified below, the planting action is performed. The spray photoelectric sensor 401 at the spraying mechanism 4 needs to be set outside the spray box 41 to avoid being affected by the spray water. Specifically, the distance between the spray head 42 and the spray photoelectric sensor 401 can be designed to be an integer multiple of the distance between the adjacent partitions 22, so that when the spray photoelectric sensor 401 identifies the seedling bag (seedling cup), there is also a seedling bag (seedling cup) below the spray head 42.

[0030] According to the working principle of the material receiving mechanism 5 and the conveyor belt 21, the conveyor belt 21 needs to be transported forward step by step with the distance between two adjacent partition plates 22 as the unit, that is, the stop position of each seedling bag (seedling cup) is determined, therefore, the position of the planting mechanism 3 and the spraying mechanism 4 also needs to be set accordingly, when the conveyor belt 21 is full of seedling bags (seedling cups), the planting mechanism 3 and the spraying mechanism 4 will also move step by step with the above rhythm. Therefore, the above-mentioned planting photoelectric sensor 301 and the spraying photoelectric sensor 401 are mainly used to identify the arrival of the first seedling bag (seedling cup), and to further ensure the accuracy of the action of the planting mechanism 3 and the spraying mechanism 4.

[0031] The above is only a preferred specific embodiment of the present invention, which is an implementation method based on the overall concept of the present invention, and the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
