[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] like Figures 1-4 As shown, a well-type chili seedling transplanter includes a mobile frame 100, which is the foundation for the entire mechanism to achieve its functions. The mobile frame 100 is equipped with a well-type hole-opening mechanism 110, a seedling separating mechanism 120, and a seedling planting mechanism 130.

[0039] The well-type hole-digging mechanism 110 is located at the front end of the mobile frame 100 and performs hole-digging operations to provide an planting environment for chili seedlings. The well-type hole-digging mechanism 110 includes a motor frame 111, a protective cylinder 112 is fixed at the bottom of the motor frame 111, a soil discharge port 1121 is opened at the upper part of the protective cylinder 112, and a hole-digging lifting drive assembly is located above the motor frame 111 to drive its up and down movement. A drilling motor 113 is fixed on the motor frame 111, and an upward spiral drill bit 114 is fixed along the motor axis of the drilling motor 113. The drill bit 114 is located inside the protective cylinder 112, and its bottom end extends out of the protective cylinder 112, so that when the well-type hole-digging mechanism 110 moves down to dig a hole, the drill bit 114 contacts the soil first.

[0040] The hole-opening lifting drive assembly includes a slide rod 115, a first cam 117, and a first rocker arm 118. The slide rod 115 is vertically arranged, with its middle portion slidably connected to a linear bearing slider 116 fixed to the movable frame 100, and its bottom portion fixed to the top of the motor frame 111. The first cam 117 is located directly above the slide rod 115, rotatably fixed to the movable frame 100, and connected to a first motor that drives its rotation. One end of the first rocker arm 118 is rotatably fixed to an eccentric position of the first cam 117, and the other end is fixed to the upper end of the slide rod 115.

[0041] When it is necessary to drive the drill bit 114 to move up and down, the first motor is started to drive the first cam 117 to rotate. Under the linkage of the first rocker arm 118, the slide bar 115 can be pulled to move up and down along the linear bearing slider 116.

[0042] The seedling separating mechanism 120 is located behind the well-type hole-opening mechanism 110. When separating seedlings, the staff needs to put the chili seedlings into the seedling tubes 123 in advance. The seedling separating mechanism 120 distributes one chili seedling to each hole to achieve precise seedling distribution. The seedling separating mechanism 120 includes a fixed plate 121 fixed on a mobile frame. The fixed plate 121 is horizontally set. A rotating shaft is rotatably fixed on the fixed plate 121 via bearings. A horizontal rotating plate 122 is fixed on the rotating shaft. The rotating shaft is connected to a rotating drive assembly that drives its rotation. Multiple seedling tubes 123 are circumferentially fixed on the rotating plate 122. The upper and lower ends of the seedling tubes 123 are open, and the lower end extends downward to the top of the fixed plate 121. The fixed plate 121 has a seedling opening that can overlap with the seedling tubes 123.

[0043] The lower end of the seedling tube 123 is very close to the fixing plate 121 to prevent the seedlings from falling between the lower end of the seedling tube 123 and the fixing plate 121. A seedling protection bowl 124 is fixed to the top of the seedling tube 123. The bottom of the seedling protection bowl 124 is connected to the seedling tube 123. On the one hand, the seedling protection bowl 124 is conical, which increases the space at the entrance of the seedling tube 123. On the other hand, the seedling protection bowl 124 can be made of silicone to prevent damage to the seedlings when they are put in.

[0044] The seedling planting mechanism 130 is located below the seedling separating mechanism 120 and is used to receive the seedlings distributed by the seedling separating mechanism 120, plant the seedlings into the holes, and cover them with soil. The seedling planting mechanism 130 includes a seedling receiving tube 131 located directly below the seedling outlet. The seedling receiving tube 131 is connected to a seedling lifting drive assembly that drives it to move up and down. A seedling planting nozzle 132 is fixed to the bottom of the seedling receiving tube 131. The seedling planting nozzle 132 can be opened under the drive of the seedling opening and closing drive assembly to discharge the seedling downwards.

[0045] The seedling nozzle 132 is a cone-shaped nozzle with the tip pointing downwards. The seedling nozzle 132 has a multi-lobed structure with circumferential division. Each lobe is rotatably connected to the seedling receiving tube 131 and is connected to a pull rope 133 that drives it to open radially. The upper end of the pull rope 133 is connected to a pulling component that pulls it up and down.

[0046] The pulling assembly includes a second cam 134, a swing arm 135, and a connecting arm 136. The second cam 134 is rotatably fixed to the mobile frame 100 and connected to a second motor that drives its rotation. The swing arm 135 rests laterally above the second cam 134, with one end of the swing arm 135 fixed to the mobile frame 100. The connecting arm 136 is rotatably connected to the other end of the swing arm 135 and is fixed to the upper end of the pull rope 133. When the second motor is started, it drives the second cam 134 to rotate. Since the swing arm 135 is located above and in contact with the second cam 134, the second cam 134 will push against the swing arm 135 and float up and down when rotating, thereby causing the connecting arm 136 to pull the pull rope 133 up and down, realizing the opening and closing of the seedling nozzle 132.

[0047] The seedling lifting drive assembly works in conjunction with the traction assembly. After the seedling nozzle 132 descends to the hole, it opens; after it rises, it closes and covers the soil. Therefore, the seedling lifting drive assembly and the traction assembly share a single drive component. The seedling lifting drive assembly includes a parallelogram connecting rod 137, a constraint assembly, a second rocker arm 139, and a guide rod.

[0048] One vertical side of the parallelogram connecting rod 137 is fixed to the side wall of the seedling receiving tube 131, and a connecting block is fixed to the other vertical side. The connecting block has a horizontal connecting surface. The constraint assembly includes two parallel constraint rods 138. The upper end of the constraint rod 138 is rotatably fixed to the motor frame 111, and the lower end is rotatably fixed to the connecting surface of the connecting block. The second rocker arm 139 has a sliding hole along its length. One end of the second rocker arm 139 is eccentrically and rotatably connected to the second cam 134, and the other end is rotatably fixed to one side of the parallelogram connecting rod 137. A guide rod is fixed to the moving frame 100 and slidably located in the sliding hole of the second rocker arm 139. The guide rod limits and guides the second rocker arm 139, causing it to swing regularly.

[0049] When the second cam 134 rotates, it drives the second rocker arm 139 to move up and down. The second rocker arm 139 drives the parallelogram connecting rod 137 to deform. When the second rocker arm 139 swings down, the parallelogram connecting rod 137 also moves down. Due to the setting of the constraint component, the movement of the parallelogram connecting rod 137 can be kept in a stable state. During the movement of the whole mechanism, the seedling receiving tube 131 can always be kept perpendicular to the horizontal plane and move almost in a straight line up and down, with very little movement in the left and right directions.

[0050] This well-type chili seedling transplanter can move on untreated field ridges. As the transplanter moves forward, it digs holes using the well-type hole-opening mechanism 110. During digging, the drill bit 114 rotates rapidly under the drive of the motor and drills into the soil, creating a deep hole. The protective cylinder 112 is used to reinforce the hole, making it less prone to collapse and providing a better environment for the well-type transplanting of chili seedlings. At the same time, the drilled soil is discharged through the soil discharge port 1121 on the side wall of the protective cylinder 112.

[0051] After digging the hole, the moving frame 100 moves forward so that the planting nozzle 132 in the planting mechanism 130 is above the hole. The rotating disk 122 rotates to a certain angle and then stops. The seedling tube 123 is aligned with the seedling outlet on the fixed disk 121. The seedling falls downward into the receiving tube 131 of the planting mechanism 130. The receiving tube 131 moves downward with the planting nozzle 132 into the hole. Then, the planting nozzle 132 opens radially under the drive of the planting opening and closing drive component, and the seedling falls into the hole. Then, the receiving tube 131 moves upward with the planting nozzle 132. Then, the planting nozzle 132 closes radially under the drive of the planting opening and closing drive component. When the petal-shaped planting nozzle 132 closes, it covers the seedling with soil, and one planting cycle is completed.

[0052] Using this pit-type chili seedling transplanter, digging holes, separating seedlings, and planting and covering soil can be completed in one go, effectively improving the efficiency of chili seedling transplanting. Furthermore, by controlling the lifting height of the motor frame 111, the depth of the pit can be adjusted, which can meet the requirements of planting in deep soil pits.

[0053] To facilitate the placement of seedlings into the seedling trays 123 by staff, a seedling trough 140 for placing seedling trays is fixed on the mobile frame 100.

[0054] Based on the required number of rows for transplanting chili seedlings, the mobile frame 100 can have multiple sets of well-type hole-opening mechanisms 110. These well-type hole-opening mechanisms 110 are arranged at equal intervals laterally. Each well-type hole-opening mechanism 110 corresponds to a grouping mechanism 120 and a planting mechanism 130. Each set of well-type hole-opening mechanism 110, grouping mechanism 120, and planting mechanism 130 corresponds to the transplanting of one row of seedlings. By setting multiple sets, multiple rows of chili seedlings can be transplanted simultaneously. Multiple rotating discs 122 can be synchronously driven by a set of pulley assemblies, and multiple first cams 117 can also be synchronously driven by a set of pulley assemblies.

[0055] The above are merely preferred embodiments of this utility model. Any simple modifications, variations, and equivalent substitutions made by any person based on the content of this utility model shall fall within the protection scope of this utility model.
