[0030] refer to Figure 1 、 Figure 2 、 Figure 8 and Figure 9 The batch transplanting equipment for forestry seedlings also includes a material guiding mechanism, which includes a connecting frame 111, a fixed bar 112, a synchronous wheel 113, a drive motor 114, a synchronous belt 115, a connecting ring 116 and a guide cylinder 117. A connecting frame 111 is welded to the middle of the mounting frame 1, and two fixed bars 112 with guide grooves are fixedly connected to the connecting frame 111. Two synchronous wheels 113 are rotatably connected to the connecting frame 111. A drive motor 114 is installed at the rear of the connecting frame 111. The output shaft of the drive motor 114 is connected to the synchronous wheel 113 on the rear side. The two synchronous wheels 113 are driven by a synchronous belt 115, which passes through the guide groove of the fixed bar 112. A circle of connecting rings 116 are fixedly connected to the synchronous belt 115 at even intervals. The connecting rings 116 are all fixedly connected to the material guide cylinder 117, and the upper ends of the material guide cylinders 117 are all funnel-shaped.

[0031] refer to Figure 1 、 Figure 2 、 Figure 8 and Figure 9The material guiding mechanism also includes a cross bar 121, a baffle 122, an inclined plate 123 and an extrusion rod 124. The outer wall of the lower end of the material guiding cylinder 117 is connected to the cross bar 121. The cross bar 121 is slidably connected with a baffle 122 for blocking the bottom end of the material guiding cylinder 117. A return spring is fixedly connected between the baffle 122 and the cross bar 121. The top of the baffle 122 is connected to an inclined plate 123 with an inclined surface. The lower part of the lifting frame 6 is fixedly connected to an extrusion rod 124, which is used to squeeze the inclined surface of the inclined plate 123.

[0032] refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 10 The batch transplanting equipment for forestry seedlings also includes a sliding mechanism, which includes a connecting column 91, a connecting plate 92, a vertical plate 93, a guide ring rod 94 and an arc block 95. All the slide bars 9 are fixedly connected to the connecting column 91. Two symmetrical connecting plates 92 are fixedly connected to the left side of the connecting column 91. Two symmetrical vertical plates 93 are fixedly connected to the left part of the mounting frame 1. The sides of the two vertical plates 93 close to each other are fixedly connected to the guide ring rod 94. The sides of the two connecting plates 92 away from each other are rotatably connected to a pair of arc blocks 95 that move along the guide ring rod 94. The inner surface of the arc block 95 is a concave arc, and there is a certain gap between the inner surface of the arc block 95 and the guide ring rod 94, so that the arc block 95 can move counterclockwise smoothly along the direction of the guide ring rod 94; the guide ring rod 94 has two vertical sections, two inclined sections 941 and two arc sections 942.

[0033] Initially, each of the four material guide barrels 117 on the left side is equipped with a sapling, the squeezing rod 124 squeezes the inclined surfaces of the four inclined plates 123 on the left side, the corresponding four return springs are in a compressed state, the four baffles 122 on the left side are in an open state, and the saplings in the four material guide barrels 117 on the left side fall down into the fixed half bucket 8 and the movable half bucket 10 directly below.

[0034] The electric push rod 2 60 is controlled to drive the lifting frame 6 to descend, driving the fixed column 7, fixed half bucket 8, slide bar 9, connecting column 91, connecting plate 92, arc block 95, mobile half bucket 10 and extrusion rod 124 to descend together. The arc block 95 descends along the vertical section on the left side of the guide ring rod 94, and the mobile half bucket 10 and the fixed half bucket 8 with a tapered bottom end extend into the soil; when the arc block 95 moves to the inclined section 941 on the lower side, under the guidance of the inclined section 941, the descending arc block 95 moves to the right at the same time. The arc block 95 can rotate to adapt to the direction of the guide ring rod 94. The right-moving arc block 95 drives the connecting plate 92, connecting column 91, slide bar 9 and mobile half bucket 10 to move to the right together, and the mobile half bucket 10 becomes open. The fixed half bucket 8 and the mobile half bucket 10 form a pit in the soil.

[0035] During the descent of the squeezing rod 124, the squeezing rod 124 will separate from the inclined plate 123, and the reset spring will restore, causing the four baffles 122 on the left to slide to the left along the cross bar 121 and close. Since the right frontmost guide cylinder 117 is aligned with the through cylinder 5 up and down, a sapling in the vertical cylinder 4 directly above the through cylinder 5 passes through the through cylinder 5 and falls into the right frontmost guide cylinder 117. The corresponding baffle 122 is in a closed state to block the sapling in the guide cylinder 117. The drive motor 114 is controlled to drive the synchronous wheel 113 on the rear side to rotate, driving the synchronous belt 115 to rotate, and driving the synchronous wheel 113 on the front side to rotate. The connecting ring 116 and the guide cylinder 117 rotate together with the synchronous belt 115, so that the next guide cylinder 117 is aligned with the through cylinder 5 up and down.

[0036] Control the reduction motor 1 to drive the pushing gear 1 42 and the pushing gear 2 43 to rotate respectively, and the pushing gear 1 42 and the pushing gear 2 43 push the vertical cylinder 4 to move, and under the transmission of the chain 41, all the vertical cylinders 4 are driven to move along the annular groove 30, so that the next vertical cylinder 4 moves to the top of the through-material cylinder 5, so that the next sapling passes through the through-material cylinder 5 and falls into the guide cylinder 117, and the chain 41 is limited by the limit block 44, the limit bar 45 and the limit edge 46 to improve the stability of the chain 41. In this way, the saplings can be loaded into the guide cylinder 117 one by one.

[0037] When the arc block 95 moves to the arc section 942 at the lower right, under the guidance of the arc section 942, the arc block 95 enters the vertical section on the right. At this time, the electric push rod 2 60 is controlled to make the lifting frame 6, fixed column 7, fixed half bucket 8, slide rod 9, connecting column 91, connecting plate 92, arc block 95, mobile half bucket 10 and extrusion rod 124 rise together, and the arc block 95 moves upward along the right vertical section, and the mobile half bucket 10 remains in an open state. The mobile half bucket 10 and the fixed half bucket 8 gradually leave the soil, and the saplings in the mobile half bucket 10 and the fixed half bucket 8 slide down along the inclined inner wall into the pit; when the mobile half bucket 10 and the fixed half bucket 8 leave the soil, the soil fills the pit under the action of gravity.

[0038] When the arc block 95 moves to the inclined section 941 on the upper side, under the guidance of the inclined section 941, the rising arc block 95 moves to the left at the same time, and the rotating arc block 95 adapts to the direction of the guide ring rod 94. The arc block 95 moving left drives the connecting plate 92, the connecting column 91, the slide bar 9 and the movable half bucket 10 to move left together, and the movable half bucket 10 becomes closed. The rising squeezing rod 124 will squeeze the inclined surfaces of the four inclined plates 123 on the left, causing the inclined plates 123 to move to the right, driving the four baffles 122 on the left to slide and open to the right, and the saplings in the four guide barrels 117 on the left can fall into the fixed half bucket 8 and the movable half bucket 10 directly below. Similarly, the saplings continue to be transplanted.

[0039] When all the saplings in the placement frame 3 are transplanted, the placement frame 3 is removed, and another placement frame 3 containing saplings is placed on the mounting plate 2. The through holes 22 are aligned with the positioning posts 21, and the positioning posts 21 are inserted into the through holes 22, thereby positioning the placement frame 3 and continuing to transplant the saplings. At the same time, the next batch of saplings to be transplanted are manually placed into the vertical tubes 4 of the removed placement frame 3, with one sapling placed in each vertical tube 4.

[0040] In this way, saplings can be continuously placed in the vertical cylinders 4 of multiple placement frames 3, improving operation continuity, and with the cooperation of the fixed half bucket 8 and the movable half bucket 10, the saplings can be automatically transplanted into the soil, improving overall work efficiency.

[0041] Example 2: Based on Example 1, refer to Figure 5 and Figure 7 The batch transplanting equipment for forestry saplings also includes a rotating rod 32 and a convex plate 33. The middle part of the mounting plate 2 is rotatably connected to the rotating rod 32 driven by the second reduction motor. The top of the rotating rod 32 is fixedly connected to the convex plate 33. The middle part of the placement frame 3 is provided with a limiting hole 31 that matches the shape of the convex plate 33; the batch transplanting equipment for forestry saplings also includes an electric push rod 34 and a top rod 35. Two electric push rods 34 are bolted to the bottom of the mounting plate 2, and the telescopic rods of the electric push rod 34 are connected to the top rod 35 for lifting the placement frame 3.

[0042] When all the saplings in the placement frame 3 are transplanted, the reduction motor 2 is controlled to rotate the rotating rod 32 and the convex plate 33 90 degrees, and the convex plate 33 is aligned with the limiting hole 31. The electric push rod 1 34 is controlled to drive the top rod 35 to move upward. The two top rods 35 lift the placement frame 3, making it easy to remove the placement frame 3 and place another placement frame 3 with saplings. When the placement frame 3 is placed on the mounting plate 2, the rotating rod 32 passes through the limiting hole 31, and the convex plate 33 is located above the limiting hole 31. The reduction motor 2 is controlled to reverse the rotating rod 32 90 degrees, driving the convex plate 33 to reverse 90 degrees. The convex plate 33 is staggered with the limiting hole 31, thereby fixing the position of the placement frame 3 by the convex plate 33 to ensure that the placement frame 3 is stably placed on the mounting plate 2.
