Description

Technical Field

[0001] The invention relates to the technical field of forestry planting, and more specifically to a large-scale forest seedling raising and fertilizing device. Background Art

[0002] The climate in Gansu is relatively dry, but there are many tree species, including drought-resistant, cold-resistant, ornamental and economically valuable tree species, such as pine, poplar, willow, elm, locust, rosewood, jujube, apple, walnut, etc. These tree species are widely planted in Gansu and are of great significance to the local ecological environment and economic development. As an important production sector for protecting the ecological environment and maintaining ecological balance, forestry cultivates and protects forests to obtain timber and other forest products, and uses the natural characteristics of forests to play a protective role. In the process of forestry planting, seedling cultivation is the main way to cultivate seedlings, and fertilization is the key link to promote the rapid growth of seedlings. For large-scale forest seedling cultivation, due to the differences in the growth of seedlings, targeted fertilization is required. However, in the case of large-scale seedling cultivation, the existing equipment applies the same amount of fertilizer to all seedlings, which violates the principle of more fertilizer for weak seedlings and less fertilizer for strong seedlings. Although it can be fertilized quickly and maintain uniformity, it is easy to gradually increase the gap for seedlings with different development conditions, increase the number of poor seedlings, and affect the seedling cultivation effect. Therefore, it is necessary to provide a large-scale forest seedling raising and fertilizing device to solve the problems raised in the above background technology. Summary of the invention

[0079] A traction frame 13 is fixed on the fixed connecting rod 12 and connected to the tractor;

[0080] Two movable frames 14 are symmetrically distributed with respect to the traction frame 13 and are slidably arranged on the control frame 11. The storage chamber 3 is fixed to the movable frame 14 via a connecting side plate, and a rotating mechanism is arranged on the connecting side plate.

[0081] That is to say, the tractor is connected to the equipment body 1 through the traction frame 13. Driven by the tractor, the equipment body 1 drives the fertilization device as a whole to move in the channel between the seedlings through the moving wheels 2. The function of the device is monitored on the tractor to identify seedlings with different development conditions, and fertilize the seedlings in a targeted manner. The mobile frame 14 moves to both sides on the control frame 11, driving the storage chamber 3, the fertilization channel 5 and related structures to move to the position of the seedlings, so as to adapt to the different intervals between the seedlings and accurately fertilize the seedlings.

[0082] In this embodiment, the fertilizer delivery device 4 includes:

[0083] The connecting frame 41 is fixed at the bottom feeding port of the material storage chamber 3, and the connecting frame 41 is provided with a connecting through hole;

[0084] Two connecting panels 42 are symmetrically arranged with respect to the connecting frame 41 and fixed on both sides of the feeding port at the bottom of the storage cavity 3;

[0085] The control shaft 43 passes through the through hole on the connection frame 41 and is rotatably connected to the two connection panels 42, and one end of the control shaft 43 is provided with a thread, and the other end provided with the thread is fixedly connected to the rotation mechanism on the connection side panel;

[0086] A fertilizer delivery wheel 44 is slidably disposed on the control shaft 43;

[0087] The adjusting assembly 45 is arranged on the control shaft 43 and is located between the fertilizer delivery wheel 44 and the rotating mechanism;

[0088] A limit spring 46 is sleeved on an end of the control shaft 43 away from the thread and is located between the fertilizer delivery wheel 44 and the connection panel 42;

[0089] The limiting annular surface 47 is rotatably disposed on a through hole at one side of the connecting frame 41 and is disposed on the same side as the fertilizer delivery wheel 44 , and the fertilizer delivery wheel 44 is slidably connected to the limiting annular surface 47 .

[0090] That is to say, the fertilizer delivery wheel 44 is pushed to move on the control shaft 43 by the adjusting component 45, and the length of the fertilizer delivery wheel 44 in the empty connection frame 41 is adjusted, so as to adjust the amount of fertilizer delivered at a single time, that is, when the adjusting component 45 pushes the fertilizer delivery wheel 44 to move in the direction where the limit spring 46 is located, the fertilizer delivery wheel 44 slides on the limit ring surface 47, compresses the limit spring 46, and at the same time, the length of the fertilizer delivery wheel 44 in the fertilization channel 5 becomes shorter, and the amount of fertilizer delivered at a single time is reduced; when the adjusting component 45 moves in the direction away from the limit spring 46, the limit spring 46 resets and pushes the fertilizer delivery wheel 44 moves in the direction of the adjusting component 45, the fertilizer delivery wheel 44 slides on the limiting annular surface 47, and then the length of the fertilizer delivery wheel 44 in the fertilization channel 5 becomes longer, and the amount of fertilizer delivered at a single time increases. Then, according to the different amounts of fertilizer required at different growth stages of the seedlings, the length of the fertilizer delivery wheel 44 in the fertilization channel 5 is adjusted by the adjusting component 45 to adapt to the amount of fertilizer required for the seedlings at different stages. When fertilizing, the rotating mechanism on the connecting side plate drives the control shaft 43 to rotate, and then the fertilizer delivery wheel 44 rotates on the connecting frame 41 through the limiting annular surface 47 to continuously deliver the fertilizer.

[0091] In this embodiment, the adjustment component 45 includes:

[0092] The regulating cylinder 451 is slidably disposed on the control shaft 43 and is fixedly connected to an end of the fertilizer delivery wheel 44 away from the limit spring 46;

[0093] The adjusting sleeve 452 is slidably disposed on the control shaft 43 and fixedly connected to the regulating cylinder 451;

[0094] The adjusting knob 453 is rotatably arranged on the thread of the control shaft 43 and fits with the adjusting sleeve 452 .

[0095] That is to say, when the adjusting knob 453 rotates forward at the thread of the control shaft 43, the adjusting knob 453 moves in the direction of the adjusting sleeve 452, pushing the adjusting sleeve 452 to move on the control shaft 43, and pushing the fertilizer delivery wheel 44 to move in the direction of the limit spring 46 through the regulating cylinder 451, and the fertilizer delivery wheel 44 slides on the limit ring surface 47 to compress the limit spring 46. At the same time, the length of the fertilizer delivery wheel 44 in the fertilization channel 5 becomes shorter, and the amount of fertilizer delivered at a single time is reduced; on the contrary, when the adjusting knob 45 When the thread of the control shaft 43 is reversed, the adjusting knob 453 moves away from the adjusting sleeve 452, and then the limit spring 46 is reset to push the fertilizer delivery wheel 44 to move in the direction of the adjusting knob 453. At the same time, the regulating cylinder 451 and the adjusting sleeve 452 move in the direction of the adjusting knob 453, and the fertilizer delivery wheel 44 slides on the limiting annular surface 47, so that the length of the fertilizer delivery wheel 44 in the fertilizer channel 5 becomes longer, and the amount of fertilizer delivered at a time increases, so that quantitative fertilization can be performed according to different growth periods of the seedlings.

[0096] In this embodiment, the interception device 6 includes:

[0097] A first bidirectional slide rail 61 is vertically arranged and fixed on the top of the moving frame 14;

[0098] The first connecting rotating assembly 62 is symmetrically provided with two groups, fixedly connected to the first bidirectional slide rail 61, and arranged on both sides of the fertilizing channel 5;

[0099] Two intercepting wheels 63 are symmetrically arranged and fixedly connected to the first connecting rotating assembly 62 respectively, and the intercepting wheels 63 pass through the side wall of the fertilizing channel 5 and enter the interior of the fertilizing channel 5;

[0100] A rotating clamp ring 64 is provided corresponding to the intercepting wheel 63, is slidably connected to the intercepting wheel 63, and is rotatably connected to the side wall of the fertilizing channel 5;

[0101] The collecting channel 65 is symmetrically distributed in two groups and is slidably set on the side wall of the fertilizing channel 5, and the top of the collecting channel 65 is in contact with the end of the intercepting wheel 63 away from the first connecting rotating component 62, and the interior of the collecting channel 65 is provided with a guide inclined plate 651 inclined toward the interior of the fertilizing channel 5.

[0102] That is to say, when the monitoring device of the tractor detects that the next seedling to be fertilized is a strong seedling, driven by the first bidirectional slide rail 61, the first connecting rotating components 62 on both sides are driven to move toward the fertilization channel 5, and then the intercepting wheel 63 is driven to slide on the rotating clamp 64, and at the same time the collecting channel 65 is driven to move into the fertilization channel 5, so that the intercepting wheel 63 and the collecting channel 65 enter the fertilization channel 5. After the intercepting wheel 63 intercepts part of the fertilizer, the first connecting rotating component 62 controls the intercepting wheel 63 to rotate, and transfers the intercepted fertilizer to the collecting channel 65. Under the guidance of the guide inclined plate 651, the intercepted fertilizer is collected in the topdressing device 7, and then the first bidirectional slide rail 61 controls the intercepting wheel 63 to reset, and the fertilizer delivery device 4 fertilizes the normally growing seedlings.

[0103] In this embodiment, the topdressing device 7 comprises:

[0104] The collecting and conveying components 71 are symmetrically arranged with respect to the fertilizing channel 5, and are fixed to the side of the fertilizing channel 5 and are located below the collecting channel 65;

[0105] A second bidirectional slide rail 72 is vertically arranged and fixed to the bottom of the moving frame 14, and the second bidirectional slide rail 72 has the same structure as the first bidirectional slide rail 61;

[0106] The second connecting and rotating components 73 are symmetrically arranged in two groups, fixedly connected to the second bidirectional slide rail 72, and arranged on both sides of the fertilizing channel 5, and the second connecting and rotating components 73 have the same structure as the first connecting and rotating components 62;

[0107] Two topdressing wheels 74 are symmetrically arranged, fixedly connected to the second connecting rotating assembly 73 and rotatably connected to the bottom of the collecting and conveying assembly 71, and the topdressing wheels 74 pass through the side wall of the fertilizing channel 5 and enter the interior of the fertilizing channel 5;

[0108] A plurality of positioning arc plates 75 are provided in an annular distribution and are slidably disposed on the topdressing wheel 74 , and the positioning arc plates 75 are rotatably connected to the bottom of the collecting and conveying assembly 71 .

[0109] That is to say, when the monitoring device of the tractor detects that the next seedling to be fertilized is a weak seedling, it determines the amount of additional fertilizer required, and then moves on the topdressing wheel 74 through the positioning arc plate 75 to adjust the groove length on the topdressing wheel 74, and then the collecting and conveying component 71 conveys the fertilizer to the adjusted groove, and then, driven by the second two-way slide rail 72, drives the second connecting rotating components 73 on both sides to move toward the fertilization channel 5, so that the positioning arc plate 75 moves to the side wall of the fertilization channel 5, and then the second connecting rotating component 73 controls the rotation of the topdressing wheel 74 to convey the fertilizer to the fertilization channel 5, increase the fertilizer delivery to the weak seedlings, so as to promote the growth and development of the weak seedlings, and after the additional fertilizer is conveyed to the fertilization channel 5, the second two-way slide rail 72 drives the topdressing wheel 74 to reset, and the fertilizer delivery device 4 fertilizes the normally growing seedlings.

[0110] In this embodiment, the collecting and conveying assembly 71 includes:

[0111] The temporary storage box 711 is fixed to the side of the fertilization channel 5 and is located below the collection channel 65;

[0112] The conveying chamber 712 is fixed at the bottom of the temporary storage box 711;

[0113] The movable baffle 713 is in a right angle shape, one side of which is slidably connected to the bottom of the conveying chamber 712, and the other side of which is rotatably connected to the topdressing wheel 74 and the positioning arc plate 75;

[0114] Two guide plates 714 are symmetrically distributed about the movable baffle 713 and fixed at the bottom of the conveying chamber 712 , and the spacing between the guide plates 714 corresponds to the grooves on the topdressing wheel 74 .

[0115] That is to say, the temporary storage box 711 collects the fertilizer collected by the collecting channel 65, and at the same time, some fertilizer can be stored in the temporary storage box 711, and then the fertilizer is transported under the action of the conveying chamber 712. Under the joint action of the guide plate 714 and the movable baffle 713, the conveying chamber 712 conveys the fertilizer to the groove of the topdressing wheel 74. When the positioning arc plate 75 moves on the topdressing wheel 74 according to the amount of fertilizer to be added, the positioning arc plate 75 drives the movable baffle 713 to move synchronously, so that the length of the groove carrying the fertilizer on the topdressing wheel 74 corresponds to the bottom conveying port of the conveying chamber 712. When the topdressing wheel 74 is moved to the topdressing wheel 74 under the action of the second bidirectional slide rail 72, the topdressing wheel 74 is moved to the topdressing wheel 74. When moving in the fertilizer channel 5, the positioning arc plate 75 drives the movable baffle 713 to close the bottom conveying port of the conveying chamber 712. When the positioning arc plate 75 moves to the side wall of the fertilization channel 5, the second connecting rotating component 73 controls the topdressing wheel 74 to rotate, and the fertilizer is conveyed to the fertilization channel 5. At the same time, the movable baffle 713 rotates on the positioning arc plate 75 and the topdressing wheel 74. After the additional fertilizer is conveyed to the fertilization channel 5, the second connecting rotating component 73 controls the topdressing wheel 74 to rotate, so that the movable baffle 713 is restored to be connected with the positioning arc plate 75, and then the topdressing wheel 74 is driven to reset through the second bidirectional slide rail 72, and the fertilizer delivery device 4 fertilizes the normally growing seedlings.

[0116] In this embodiment, the bidirectional slide rail includes:

[0117] A connecting plate 611 is fixedly connected to the mobile frame 14;

[0118] A center positioning member 612 is fixed to the middle of the connecting plate 611;

[0119] Two rotating shafts 613 are symmetrically arranged about the central positioning member 612 and driven by a motor;

[0120] The movable platform 614 is arranged corresponding to the rotating shaft 613 and is fixed on the rotating shaft 613 via a threaded sleeve.

[0121] That is to say, under the restriction of the central positioning member 612, the motor drives the rotating shafts 613 on both sides to rotate in opposite directions, driving the moving platform 614 to move synchronously toward the center or both sides, and adjusting the positional relationship between the intercepting wheel 63 and the topdressing wheel 74 and the fertilization channel 5 by connecting the rotating components, that is, when the rotating shaft 613 drives the moving platform 614 to move synchronously toward the center, the intercepting wheel 63 and the topdressing wheel 74 are driven to move toward the inside of the fertilization channel 5 by connecting the rotating components, and the fertilizer is intercepted by the intercepting device 6, or the topdressing device 7 increases the amount of fertilizer; when the rotating shaft 613 drives the moving platform 614 to move synchronously toward the outside, the intercepting wheel 63 and the topdressing wheel 74 are driven to move toward the outside of the fertilization channel 5 by connecting the rotating components, and the fertilizer delivery device 4 fertilizes the normally growing seedlings.

[0122] In this embodiment, the connecting and rotating assembly includes:

[0123] A connecting member 621 is fixed on the moving platform 614;

[0124] The rotating motor 622 is fixed on the connecting member 621, and the rotating motor 622 is fixedly connected to the corresponding intercepting wheel 63 and the topdressing wheel 74 respectively.

[0125] That is to say, under the connecting action of the connecting piece 621, the movable platform 614 drives the intercepting wheel 63 and the topdressing wheel 74 to move and adjust through the rotating motor 622, and the rotating motor 622 drives the intercepting wheel 63 to rotate, collects the intercepted fertilizer, drives the topdressing wheel 74 to rotate, and transports the additional fertilizer to the fertilization channel 5.

[0126] In the specific implementation, first, according to the spacing between the seedlings, the mobile frame 14 moves on the control frame 11, driving the storage chamber 3 and the fertilizer channel 5 and related structures to move to the position of the seedlings, so as to adapt to the different spacings between the seedlings and accurately fertilize the seedlings. Then, driven by the tractor, the equipment body 1 drives the fertilization device as a whole to move in the channel between the seedlings through the mobile wheel 2, the trenching knife 8 digs the trench, the fertilizer port 51 transports the fertilizer, and then the leveling component 9 covers the soil. Then, the function of the monitoring device on the tractor is used to identify the seedlings with different development conditions, and the seedlings are fertilized in a targeted manner. Then, according to the growth period of the seedlings, the amount of fertilizer is determined, and the adjustment knob 453 is controlled to adjust the amount of fertilizer. The control shaft 43 is rotated at the thread to control the fertilizer delivery wheel 44 to move on the control shaft 43, and the length of the fertilizer delivery wheel 44 in the fertilization channel 5 is adjusted to determine the single fertilizer amount. When the seedlings are in a normal development state, the fertilizer is transported to the fertilization channel 5 through the fertilizer delivery device 4, and precise fertilization is carried out through the fertilizer port 51; when the monitoring device of the tractor detects that the next fertilized seedling is a strong seedling, the first connecting rotating components 62 on both sides are driven by the first bidirectional slide rail 61 to move toward the fertilization channel 5, and then the intercepting wheel 63 is driven to slide on the rotating clamp 64, and at the same time the collecting channel 65 is driven to move into the fertilization channel 5, so that the intercepting wheel 63 and the collecting channel 65 enter the fertilization channel 5, and then the collecting channel 65 is driven to move into the fertilization channel 5. After the intercepting wheel 63 intercepts part of the fertilizer, the first connecting rotating assembly 62 controls the intercepting wheel 63 to rotate, and transfers the intercepted fertilizer to the collecting channel 65. Under the guidance of the guide inclined plate 651, the intercepted fertilizer is collected in the temporary storage box 711, and then the first bidirectional slide rail 61 controls the intercepting wheel 63 to reset, and the fertilizer delivery device 4 fertilizes the normally growing seedlings; when the monitoring device of the tractor detects that the next seedling to be fertilized is a weak seedling, it determines the amount of additional fertilizer required, and then controls the positioning arc plate 75 to move on the topdressing wheel 74, adjusts the groove length on the topdressing wheel 74, and then the collecting and conveying assembly 71 delivers the fertilizer to the adjusted groove, and then driven by the second bidirectional slide rail 72 Down, drive the second connecting rotating components 73 on both sides to move toward the fertilization channel 5, make the positioning arc plate 75 move to the side wall of the fertilization channel 5, and then the second connecting rotating component 73 controls the topdressing wheel 74 to rotate, and transports the fertilizer to the fertilization channel 5, increases the fertilizer delivery to the weak seedlings to promote the growth and development of the weak seedlings. After the additional fertilizer is transported to the fertilization channel 5, the second two-way slide rail 72 drives the topdressing wheel 74 to reset, and the fertilizer delivery device 4 fertilizes the normally growing seedlings. Through the cooperation between the fertilizer delivery device 4, the intercepting device 6 and the topdressing device 7, the seedlings with different growth and development in the same forest land are accurately fertilized, which effectively avoids the excessive growth of strong seedlings and promotes the growth and development of weak seedlings.
