Description

Technical Field

[0001] The present invention relates to an intelligent fertilization device for soil restoration, and in particular to an intelligent fertilization device for soil restoration of degraded forest land applied in the field of planting and fertilization. Background Art

[0002] Soil restoration of degraded forest land is of great significance in rebuilding forest ecological functions, curbing the spread of land degradation, improving regional environmental quality and creating economic value. During the soil restoration process, the soil needs to be fertilized, and the surface of the soil is generally fertilized by spreading or irrigation.

[0003] The specification of Chinese invention patent CN117694069B discloses a thin-shell pecan fertilizing device with adjustable fertilizer amount. By changing the spatial size of the fertilizer storage in the quantitative box, it is beneficial to achieve the adjustment and control of the single fertilizer amount. By providing a fertilizer head, the fertilizer is directly applied into the soil, thereby effectively reducing the probability of fertilizer loss after application, which is beneficial to ensure the stability of fertilization.

[0004] The specification of Chinese invention patent CN116724738B discloses a fertilizing device for cultivated land with adjustable fertilizer amount, which solves the problems of uneven spreading of feces fertilizer and difficulty in thorough cleaning of the interior after use of the existing fertilizing device for cultivated land with adjustable fertilizer amount.

[0005] In the process of fertilizing, existing fertilization devices generally adopt shallow fertilization operations. Even if there is soil burial, the depth of fertilization in the soil layer is shallow, resulting in that the type of fertilizer applied is usually quick-acting fertilizer, which is not conducive to the application of slow-release fertilizer. In addition, when the existing fertilization device is working, it usually fertilizes a single type of fertilizer. When operating slow-release fertilizer and quick-acting fertilizer, they need to be performed separately, resulting in limited fertilization efficiency. Summary of the invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to enable the fertilization device to realize the synchronous fertilization operation of slow-release fertilizer and quick-acting fertilizer, and to perform two single-mode fertilization treatments according to actual needs, thereby improving the fertilization efficiency while taking into account different fertilization needs.

[0007] In order to solve the above problems, the present invention provides an intelligent fertilizing device for soil restoration of degraded forest land, comprising a fertilizer box, a movable wheel is installed at the bottom of the fertilizer box through a bracket, an isolation plate is installed at a central position inside the fertilizer box, a No. 2 motor is installed on one side outer wall of the fertilizer box, a rotating barrel is connected through the bottom of the fertilizer box, a rotating rod is rotatably connected inside the rotating barrel, a plurality of partitions are installed on the surface of the rotating rod, and the output end of the No. 2 motor is connected to one end of the rotating rod through a transmission belt, and the bottom of the rotating barrel is connected to a discharging frame through a hose;

[0010] In the above-mentioned intelligent fertilization device for soil restoration of degraded forest land, the deep insertion unit cooperates with the arc-shaped teeth driven by the No. 3 motor to realize deep soil covering fertilization and soil isolation between the two fertilization layers. The slow-release fertilizer and the quick-acting fertilizer are separated by an isolation plate in the fertilizer box, and the bottom rotating barrel realizes precise packaging of fertilizers through a rotating partition with a movable partition.

[0011] As a further improvement of the present application, the gear part is a quarter gear, and in the initial state, the teeth on the surface of the gear part are close to the direction of the rotating rod. After the movable rack is rotated 90 degrees, it is placed vertically and in contact with the surface of the adjacent partition. When the movable partition is placed horizontally, it has the same horizontal axis as the surface of the partition.

[0012] As a further improvement of the present application, a No. 3 motor is installed on the two side surfaces of the rotating barrel, the output end of the No. 3 motor is connected to a driving gear, the surface of the rotating barrel is slidably connected to an arc-shaped toothed part meshing with the driving gear, and the surface of the arc-shaped toothed part is connected to the surface of the hydraulic telescopic rod.

[0013] As a further improvement of the present application, two stirring rods are installed inside the fertilizer box and are located on both sides of the isolation plate. A motor No. 1 is installed on the outer wall on the other side of the fertilizer box. The output end of motor No. 1 is connected to the end of one of the stirring rods, and the ends of the two stirring rods are connected by a transmission belt.

[0014] As a further improvement of the present application, the hydraulic telescopic rod is arranged tilted in the initial state, the center of the arc-shaped tooth part is located below the left side of the stainless steel plate when the hydraulic telescopic rod is extended to the maximum value in the initial state, and the bottom end of the arc-shaped tooth part is located above the moving wheel in the initial state.

[0015] As a further improvement of the present application, the distance between the hydraulic telescopic rod and the outer wall of the rotating barrel is greater than the thickness of the conveyor belt connected to the output end of the second motor.

[0016] As a further improvement of the present application, a No. 1 blocking plate and a No. 2 blocking plate are installed near the bottom of the fertilizer box, which are slidably connected to the inside of the fertilizer box and are both made of permanent magnets.

A magnetic blocking plate is slidably connected to the inside of the discharging frame, and an electromagnetic frame with a C-shaped cross-section is connected to the surface of the discharging frame.

[0019] To summarize, the deep insertion unit consists of a hydraulic telescopic rod, an L-shaped rod and a stainless steel plate.

The slow-release fertilizer and the quick-acting fertilizer are separated by an isolation plate in the fertilizer box. The bottom transfer barrel realizes precise fertilizer packaging through a rotating partition with a movable partition. The slow-release fertilizer sinks into the bottom layer of the V-shaped port after being isolated by the movable partition, and the quick-acting fertilizer subsequently covers the upper layer. In addition, with the cooperation of the hydraulic telescopic rod, the discharge hood and the feed port, the isolated soil layer can be conveniently covered. The overall structure realizes the precision and automation of layered restoration and fertilization of degraded forest land through electromechanical coordination. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following will make a detailed description of the two embodiments of this application with reference to the accompanying drawings.

[0038] The first embodiment:

[0039] Figures 1 - 3 There is shown an intelligent fertilizing device for degraded forest land soil remediation, including a fertilizer tank 1. The bottom of the fertilizer tank 1 is installed with moving wheels through brackets. In the middle position inside the fertilizer tank 1, a partition board is installed. On one outer wall of the fertilizer tank 1, a second motor 3 is installed. The bottom of the fertilizer tank 1 is connected through a through hole to a material transfer cylinder 4. Inside the material transfer cylinder 4, a rotating rod is rotatably connected. On the surface of the rotating rod, a plurality of partition boards 13 are installed. And the output end of the second motor 3 and one end of the rotating rod are connected through a transmission belt. The bottom of the material transfer cylinder 4 is connected to a discharge frame 12 through a hose;

[0040] Figures 4 - 5 There is shown that on both side surfaces of the material transfer cylinder 4, deep insertion units are installed. The deep insertion unit includes a hydraulic telescopic rod 6. The output end of the hydraulic telescopic rod 6 is fixedly connected to a stainless steel plate 11 through an L-shaped rod. And the surface of the stainless steel plate 11 near the top is connected to the surface of the discharge frame 12 (the connection between the stainless steel plate 11 and the discharge frame 12 enables the discharge frame 12 to move synchronously and discharge materials when the stainless steel plate 11 moves in an arc, avoiding discharge deviation);

[0041] Figures 6 - 7 There is shown that on the surface of the partition board 13, there are depressions. Inside the depressions, a movable partition board 134 is connected through a shaft rod. On the surface of the shaft rod, a gear member 133 is connected. Inside the partition board 13, an electromagnetic member 131 and a movable rack 132 made of a permanent magnet engaging with the gear member 133 are installed.

[0042] The gear member 133 is a quarter gear. And in the initial state, the teeth on the surface of the gear member 133 face the direction of the rotating rod. After the movable rack 132 rotates 90 degrees, it is vertically placed and fits and contacts with the surface of the adjacent partition board 13. When the movable partition board 134 is horizontally placed, it is on the same horizontal axis as the surface of the partition board 13.

[0043] On both side surfaces of the material transfer cylinder 4, third motors 5 are installed. The output end of the third motor 5 is connected to a driving gear. On the surface of the material transfer cylinder 4, an arc-shaped tooth member 7 engaging with the driving gear is slidably connected. And the surface of the arc-shaped tooth member 7 is connected to the surface of the hydraulic telescopic rod 6.

[0044] Specifically, when performing ordinary surface fertilization, the deep insertion unit is not started. The same fertilizer is placed in the spaces separated by the two partition boards. Through the rotating partition board 13, the fertilizer entering the material transfer cylinder 4 can be evenly separated. Then it is discharged through the discharge frame 12. Through the moving fertilizer tank 1, uniform fertilization operation can be carried out on the ground surface. In addition, during this process, if it is necessary to control the discharge amount in the discharge frame 12 each time, controlling the rotation speed of the partition board 13 can control the feeding amount in each cavity of the material transfer cylinder 4, and thus indirectly achieve the purpose of controlling the discharge amount.

[0045] When applying deep fertilization (i.e., slow-release fertilizer, the depth of fertilizer addition is greater than that of quick-acting fertilizer), the fertilizer box 1 can be kept stationary first, and then the hydraulic telescopic rod 6 is started. The stainless steel plate 11 is tilted and inserted into the soil layer. Then, the third motor 5 is started. Driven by the driving gear, the arc-shaped tooth part 7 moves arc-shaped to the left, thereby driving the stainless steel plate 11 inserted into the soil layer to move synchronously, exerting a squeezing effect on the soil on the side of the stainless steel plate 11 away from the discharge frame 12, so that a V-shaped opening is formed at the position where the stainless steel plate 11 is inserted (as Figure 10 shown. If during this process, the soil is relatively hard, to avoid bending damage to the stainless steel plate 11 during the lifting process, the stainless steel plate 11 can be pulled out first, and then the hydraulic telescopic rod 6 and the stainless steel plate 11 are used to insert deeply into the soil layer multiple times to break up the soil blocks, so as to reduce the resistance encountered during subsequent lifting). Then, the electromagnetic frame 10 generates an attraction effect with the magnetic moving plug plate 121, driving the magnetic moving plug plate 121 to slide, opening the discharge frame 12. After releasing the slow-release fertilizer, the electromagnetic frame 10 generates a repulsive effect with the magnetic moving plug plate 121, and the magnetic moving plug plate 121 blocks the discharge frame 12.

[0046] After that, the third motor 5 rotates in the reverse direction. After driving the arc-shaped tooth part 7 to return to the initial state, the hydraulic telescopic rod 6 retracts. The lifted soil blocks cover the surface of the slow-release fertilizer under the action of inertia, ending the deep fertilization.

[0047] Figures 8 - 9It is shown that when slow-release fertilizers and quick-acting fertilizers need to be added simultaneously, the specific types of slow-release fertilizers and quick-acting fertilizers need to be considered, as well as the feasibility of applying the two fertilizers simultaneously (since some slow-release fertilizers and quick-acting fertilizers cannot be applied simultaneously due to reactions, the environment in which this application is used is that the two fertilizers can be applied simultaneously and there is no need to consider the situation of separating soil in the middle). The slow-release fertilizer and the quick-acting fertilizer are added on both sides of the partition board respectively (assuming that in this application, the slow-release fertilizer is added to the space where the first plug board 81 is located, hereinafter referred to as the first space, and the quick-acting fertilizer is added to the space where the second plug board 91 is located, hereinafter referred to as the second space). Subsequently, first start the second electromagnetic block 92 to generate a magnetic attraction effect to drive the second plug board 91 to release the blockage of the second space. During this process, when the cavity formed by every two adjacent partition boards 13 rotates to the discharge port of the adjacent first space after passing through the discharge port of the second space (the cross-section of the discharge port at the bottom of the fertilizer tank 1 straddles the positions of two cavities), and at this time the discharge port of the first space is in a closed state, start the electromagnetic member 131 (inside the partition board 13 facing away from the second discharge port in this cavity) to drive the movable rack 132 to move, and then drive the gear member 133 to rotate 90 degrees, so that this cavity is isolated. After the first space is opened subsequently, through rotation, the addition of the slow-release fertilizer is realized (during the above process, it is necessary to control the rotation speed of the second motor 3 to avoid the mixing of slow-release fertilizer and quick-acting fertilizer due to insufficient time for the movable partition board 134 to switch isolation caused by too fast rotation speed, and it is necessary to control the time points of discharging in the first space and the second space, and control the feeding amount in each cavity).

[0048] After realizing layered storage, use the deep insertion unit to create a V-shaped opening. Then, when the cavity rotates to the connection position between the transfer cylinder 4 and the hose, after opening the discharge channel in the discharge frame 12, the slow-release fertilizer on one side of the movable partition board 134 first falls to the bottom layer of the V-shaped opening. Subsequently, the electromagnetic member 131 is started to drive the movable partition board 134 to reset, and the quick-acting fertilizer in this cavity can be released, so that it can be stacked on the upper layer of the slow-release fertilizer, realizing the simultaneous addition of the two fertilizers.

[0049] When it is necessary to add an isolation soil layer between two layers of fertilizers, the stainless steel plate 11 can be first inserted downward. Subsequently, the stainless steel plate 11 is driven by the swing of the arc-shaped tooth part 7 to be lifted to form a V-shaped opening, and the slow-release fertilizer is first released. Then, with the help of the arc-shaped tooth part 7, the stainless steel plate 11 is reset. Subsequently, after the hydraulic telescopic rod 6 drives the stainless steel plate 11 to be pulled out a certain distance, at this time, the tail end of the stainless steel plate 11 is close to the soil surface while still having part buried in the soil layer. After that, the third motor 5 is used to drive the arc-shaped tooth part 7 to drive the hydraulic telescopic rod 6 and the stainless steel plate 11 to swing to the left to form a second V-shaped opening for the addition of quick-acting fertilizer, so as to achieve the purpose of having an isolation soil layer between the two fertilizers (because the surface soil is relatively loose, by adjusting the tip point of the V-shaped opening, intermediate isolation can be achieved. If the surface soil is also relatively consolidated, then the hydraulic telescopic rod 6 needs to drive the stainless steel plate 11 to be pulled out of the soil layer, continue to swing to the left, adjust the inclination degree of the hydraulic telescopic rod 6, and then continue to extend and insert, and then lift to release the quick-acting fertilizer, which can also achieve the creation of the isolation soil layer).

[0050] The hydraulic telescopic rod 6 is arranged obliquely in the initial state. The center of the arc-shaped tooth part 7 is located below the left side of the stainless steel plate 11 when the hydraulic telescopic rod 6 extends to the maximum value in the initial state, and the bottom end of the arc-shaped tooth part 7 is located above the moving wheel in the initial state.

[0051] Specifically, due to the design of the center position of the arc-shaped tooth part 7, when the hydraulic telescopic rod 6 does not extend to the maximum value, at this time, when the arc-shaped tooth part 7 moves along with the driving gear in an arc, it can still drive the stainless steel plate 11 to move in an arc, thereby creating a V-shaped opening (as Figure 11 shown).

[0052] Two stirring rods are installed inside the fertilizer box 1 on both sides of the isolation plate. A first motor 2 is installed on the outer wall of the other side of the fertilizer box 1. The output end of the first motor 2 is connected to the end of one of the stirring rods, and the ends of the two stirring rods are connected by a conveyor belt for transmission.

[0053] Specifically, through the drive of the first motor 2, the anti-caking treatment of the fertilizers in the spaces on both sides of the isolation plate can be realized.

[0054] The distance value between the hydraulic telescopic rod 6 and the outer wall of the transfer cylinder 4 is greater than the thickness value of the conveyor belt connected to the output end of the second motor 3.

[0055] Specifically, the difference between the distance value and the thickness value can enable the hydraulic telescopic rod 6 to swing without being blocked by the conveyor belt during the swing, thereby ensuring its stable swinging movement.

[0056] A first blocking plate 81 and a second blocking plate 91 which are slidably connected to the inside of the fertilizer box 1 and are both made of permanent magnets are installed near the bottom of the fertilizer box 1. An electromagnetic block 82 and a second electromagnetic block 92 are fixedly connected to the bottom of the fertilizer box 1. A magnetic blocking plate 121 is slidably connected to the inside of the discharging frame 12, and an electromagnetic frame 10 with a C-shaped cross-section is connected to the surface of the discharging frame 12.

[0057] Specifically, through the electromagnetic repulsion and electromagnetic attraction, a corresponding switching effect is played, thereby realizing the closing and unblocking of the discharge passage.

[0058] The second implementation method:

[0059] Figures 12 - 14 It is shown that a bracket is slidably connected to the surface of the stainless steel plate 11 on the side away from the discharge frame 12 near the top, a rotating earth-moving wheel 14 is rotatably installed on the end of the bracket, a motor is installed at one end of the bracket, and the output end of the motor is connected to the end of the rotating earth-moving wheel 14, and an arc-shaped discharge cover 15 with a hollow interior is installed on the side of the stainless steel plate 11 near the top.

[0060] The tail end of the discharge cover 15 is located between the stainless steel plate 11 and the discharge frame 12 , and a feed port 151 is provided at the bottom of the discharge cover 15 , and a plurality of arc-shaped rubber sheets 152 arranged around the inner wall of each feed port 151 are installed.

[0061] Different from the first embodiment, this embodiment is mainly used for convenient addition of an isolation soil layer in the first embodiment, and a small electric extension rod is installed in this embodiment for adjusting the position of the bracket on the surface of the stainless steel plate 11. The operation of adding the isolation soil layer in the first embodiment is relatively cumbersome, so this embodiment is adopted for improvement.

[0062] Specifically, when it is necessary to add an isolation soil layer to the surface of the slow-release fertilizer, the small electric extension rod is started to adjust the position of the bracket to the surface of the uncovered soil body, and then the motor is started to drive the rotary soil wheel 14 to rotate, so that the surface of the uncovered soil body can be broken up and disturbed to the surface of the discharge cover 15, and the broken small soil blocks hit the feed port 151 surrounded by the rubber sheet 152, and then transferred to the middle of the stainless steel plate 11 and the discharge frame 12 through the curvature of the discharge cover 15, and fall to the surface of the slow-release fertilizer in the V-shaped mouth (such as Figure 15 As shown), an isolation soil layer is formed (because the rubber sheet 152 has a certain load-bearing capacity, under the rapid impact of the small soil blocks, the small soil blocks carry kinetic energy and can smoothly enter the feed port 151, but after entering the discharge cover 15, the feed port 151 can be blocked by the rubber sheet 152 by its own gravity, thereby having a better interception effect on the small soil blocks).

[0063] In summary, the deep insertion unit is composed of a hydraulic telescopic rod 6, an L-shaped rod, and a stainless steel plate 11. In cooperation with the arc-shaped tooth part 7 driven by the third motor 5, the stainless steel plate 11 moves in an arc to form a V-shaped fertilization opening, realizing deep soil covering and fertilization and the soil layer isolation between the two fertilization layers. The slow-release fertilizer and the quick-acting fertilizer are separated by a partition plate in the fertilizer tank 1. The bottom material transfer cylinder 4 realizes precise fertilizer packaging through the rotating partition plate 13 with a movable partition plate 134. After being isolated by the movable partition plate 134, the slow-release fertilizer sinks to the bottom layer of the V-shaped opening, and the quick-acting fertilizer then covers the upper layer. In addition, in cooperation with the hydraulic telescopic rod 6, the discharge cover 15, and the feed inlet 151, the convenient covering of the isolated soil layer can be realized. The overall structure realizes the precision and automation of stratified restoration fertilization in degraded forest land through the coordination of mechanical and electrical systems.

[0064] Combined with the current actual requirements, the above implementation method adopted in this application, the scope of protection is not limited to this. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
