Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and in particular to a fertilizer application device for tobacco-growing soil. Background Technology

[0002] Soil carbon sequestration refers to the process of fixing atmospheric carbon dioxide in the soil through various measures to increase soil carbon storage and mitigate climate change.

[0003] In my country's tobacco-producing areas, such as Guizhou, there are many types and quantities of tobacco-growing soils. In order to improve the carbon sequestration capacity of tobacco-growing soils and to ensure the yield of grain crops, some areas adopt the intercropping model of tobacco and grain crops, such as planting tobacco and purple sweet potatoes. Due to the differences in the nutritional requirements and spraying requirements of tobacco and purple sweet potatoes, when growers use conventional fertilizer spraying equipment to apply fertilizer, they often need to mix fertilizer multiple times and work back and forth in the field many times, resulting in excessive labor intensity and low overall spraying efficiency.

Detailed Implementation

[0030] Some embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0031] Currently, when growers use conventional fertilizer spraying equipment to apply fertilizer to tobacco-growing soil, they often need to mix fertilizer multiple times and work back and forth in the field, resulting in excessive labor intensity and low overall spraying efficiency.

[0032] Therefore, this application provides an innovative fertilizer application device for tobacco-growing soil, which includes a frame, a storage component, a spraying component, and a walking component.

[0033] Before applying fertilizer, push the device to the field and rotate the positioning legs to place them on the ground, allowing them to stably support the frame. Then, adjust the sliding positioning wheels according to the distance between the tobacco and sweet potato rows, widening or narrowing the distance between the wheels in the same row. This allows the device to span both tobacco and sweet potato rows, facilitating operation on different crops. After adjustment, retract the positioning legs and lower the frame. All the wheels then support the frame. Next, pour fertilizer of a certain concentration into the supply tank and water into the replenishment tank. Connect the replenishment tank to the corresponding supply tank as needed to complete the fertilizer mixing. Then, drive the wheels to rotate, moving the device along the length of the row and opening the corresponding spray heads, allowing the fertilizer of the required concentration to be sprayed onto the target crop. Compared with existing technologies, this application reduces the steps and time of manual fertilizer mixing by diluting the supply box with the replenishment tank, and achieves spraying operations with different row spacing by adjusting the spacing of the walking wheels, and achieves spraying of different crops by coordinating different spray heads with corresponding supply boxes, thereby reducing the number of trips to the field, reducing labor intensity and improving fertilizer spraying efficiency.

[0034] The present invention will be specifically described below through specific embodiments.

[0035] Reference Figures 1 to 2 As shown, Figure 1 The present application provides a fertilizer dispensing device for tobacco-growing soil, as shown in the schematic diagram of the deployed positioning leg 42. The device includes a frame 1, a storage component 2, a spraying component 3, and a walking component 4. The storage component 2 is mounted on the frame 1 and includes at least one replenishment tank 23 and at least one supply tank. Any supply tank is connected to one or more replenishment tanks 23, and the number of supply tanks includes two or more. The spraying component 3 includes at least one spray head slidably connected to the frame 1, and any spray head is connected to a supply tank. The walking component 4 is mounted on the frame 1 and includes a positioning leg 42 and at least two walking wheels. The positioning leg 42 is rotatably connected to the frame 1, and at least one of the walking wheels is slidably connected to the frame 1. When the positioning leg 42 rotates relative to the frame 1, the positioning leg 42 can raise or lower the frame 1.

[0036] Before applying fertilizer, push the device to the field and rotate the positioning legs 42 to place them on the ground, allowing them to stably support the frame 1. Then, adjust the sliding positioning wheels according to the distance between the tobacco and sweet potato rows, widening or narrowing the distance between the wheels in the same row. This allows the device to span both tobacco and sweet potato rows, facilitating operation on different crops. After adjustment, retract the positioning legs 42 and lower the frame 1. All the wheels then support the frame 1. Next, pour fertilizer of a certain concentration into the supply box and water into the replenishment tank 23. Connect the replenishment tank 23 to the corresponding supply box as needed to complete the fertilizer mixing. Then, drive the wheels to rotate, moving the device along the length of the row and opening the corresponding spray heads, allowing the fertilizer of the corresponding concentration to be sprayed onto the target crop as required. Compared with the prior art, this application reduces the steps and time of manual fertilizer mixing by diluting the supply box through the replenishment tank 23, and achieves spraying operations with different row spacing by adjusting the spacing of the walking wheels, and achieves spraying of different crops by coordinating different spray heads with corresponding supply boxes, thereby reducing the number of trips to the field, reducing labor intensity and improving fertilizer spraying efficiency.

[0037] Understandably, the number of replenishment tanks 23 and supply tanks can be flexibly adjusted according to actual spraying requirements. In this embodiment, the field is planted with two crops: purple sweet potato and tobacco. Accordingly, two supply tanks are set, each containing a certain concentration of fertilizer. One replenishment tank 23 is provided, connected to both supply tanks, and contains a solution for diluting the fertilizer, such as liquid purified water. For ease of distinction, the two supply tanks are named First Tank 21 and Second Tank 22, respectively.

[0038] Of course, the number and type of spray heads can be flexibly adjusted according to actual spraying requirements. In this embodiment, there are two spray heads, each connected to a different supply box. For easy distinction, the two spray heads are named the first spray head 32 and the second spray head 33, respectively. Correspondingly, the first spray head 32 is connected to the first box 21, and the second spray head 33 is connected to the second box 22. For ease of installation, a guide frame 31 is installed on the frame 1, and the first spray head 32 and the second spray head 33 are slidably connected to the guide frame 31.

[0039] Furthermore, the number and distribution of the traveling wheels can be flexibly adjusted according to the actual conditions of the field. For example, four traveling wheels can be set, similar to the four wheels of a car, with the direction of travel as the column direction. The traveling wheels in a certain column direction can slide relative to the frame 1. Then, by adding a connecting shaft with a telescopic structure between the traveling wheels in the column direction, the synchronous rotation of the traveling wheels in the same column can be achieved. Alternatively, a motor with dual drive shafts can be added to the bottom, and the motor is connected to the sliding traveling wheels through a connecting shaft with a telescopic structure, thereby achieving automatic movement of the device. In this embodiment, two traveling wheels are set and arranged side by side, meaning that the rotation axes of the two traveling wheels are collinear. In addition, a steering structure is provided between the traveling wheels and the frame. For example, a connecting shaft is added between the two traveling wheels, and a universal joint-like steering structure is added in the middle of the intermediate shaft. The steering structure is then connected to the frame, thereby enabling the device to turn during movement. The specific structure is existing technology and will not be described in detail here. For easy distinction, the two traveling wheels are named the first traveling wheel 41 and the second traveling wheel 44, respectively. The second traveling wheel 44 can slide relative to the frame 1. At the same time, for easy installation, a sliding frame 43 is installed on the frame 1. The second traveling wheel 44 is connected to the sliding frame 43, and the first traveling wheel 41 is fixedly connected to the sliding frame 43.

[0040] In this embodiment, before applying fertilizer, the device is pushed to the field, and the positioning leg 42 is rotated to stably support the frame 1, thus placing the device stably on the ground. Then, the distance between the second traveling wheel 44 and the first traveling wheel 41 is adjusted according to the distance between the tobacco row and the sweet potato row, allowing the device to operate across the tobacco row and the sweet potato row. After adjustment, the positioning leg 42 is retracted, and the first traveling wheel 41 and the second traveling wheel 44 begin to support the frame 1, keeping the device stably placed on the ground; then... Fertilizer of a certain concentration is poured into the first container 21 and the second container 22 respectively. Then, a certain amount of water is poured into the replenishment tank 23. The replenishment tank 23 is then connected to the first container 21 and the second container 22 for a certain period of time as needed, thus completing the mixing ratio of the two fertilizers. Next, the first traveling wheel 41 and the second traveling wheel 44 are driven by external force to rotate, thereby moving the entire device along the length of the ridge and opening the first spray head 32 and the second spray head 33 respectively, so that the corresponding concentration of fertilizer is sprayed onto the corresponding crops. Compared with the prior art, this application reduces the steps and time of manual fertilizer mixing and can simultaneously apply fertilizer to different crops, thereby significantly reducing the number of trips back and forth in the field, reducing labor intensity, and improving fertilizer spraying efficiency.

[0041] It is understood that the shapes of the supply box and the replenishment box 23 can be arbitrary. That is, the shapes of the first box 21, the second box 22, and the replenishment box 23 can be regular shapes such as cylinders and prisms, or any other irregular shapes, as long as they can hold a certain amount of fertilizer. In this embodiment, the first box 21, the second box 22, and the replenishment box 23 are all cuboid in shape, and their internal spaces are also cuboid in shape.

[0042] In this embodiment, the pipelines between the replenishment tank and the first and second tanks are equipped with butterfly valves or ball valves that can control the flow rate and open / close, so as to adjust the liquid volume entering the corresponding tank.

[0043] In some examples, the replenishment tank 23 is connected to the supply tank via a pipeline, and the connecting pipeline is equipped with a one-way valve 231. The one-way valve 231 prevents the fertilizer solution in the first tank 21 and / or the second tank 22 from flowing into the replenishment tank 23, thereby affecting the purity of the fertilizer dilution solution (such as liquid purified water) in the replenishment tank 23.

[0044] In some examples, the replenishment tank 23 is positioned above the supply tank. In this embodiment, the replenishment tank 23 is positioned above the first tank 21 and the second tank 22. In this embodiment, the substance placed in the replenishment tank 23 is liquid purified water; the substance placed in the first tank 21 and the second tank 22 is a potassium fertilizer solution with a certain concentration. When planting tobacco and purple sweet potatoes, at a certain stage, the potassium fertilizer concentration required for tobacco is higher than that for purple sweet potatoes. In actual operation, it is only necessary to first prepare a potassium fertilizer solution of the same concentration, and then use the water in the replenishment tank 23 to dilute the potassium fertilizer solution in the target tank. By placing the replenishment tank 23 on top of the other tanks, the water in the other tanks can flow into the corresponding tank mainly by gravity, thereby avoiding the use of a pump or reducing the energy consumption caused by using a pump.

[0045] In some examples, refer to Figure 2 As shown, a stirring assembly 5 is provided inside the supply tank. In this embodiment, the stirring assembly 5 is provided inside both the first tank 21 and the second tank 22. In this embodiment, the stirring assembly 5 is electrically connected to a valve on the corresponding pipeline that controls the flow rate. When the corresponding valve is opened, and the replenishment tank 23 is connected to the first tank 21 and / or the second tank 22, the stirring assembly 5 inside the corresponding tank begins to operate, thereby enabling the liquid flowing into the replenishment tank 23 to quickly mix with the existing liquid in the corresponding tank, improving the mixing efficiency. Figure 2 An exemplary internal structural diagram of the first housing 21 is shown.

[0046] For example, the stirring assembly 5 includes a base 51 and a movable rod 52 slidably connected to the base 51. Blades 53 are distributed on the sidewall of the movable rod 52. The movable rod 52 reciprocates along the sliding direction under the drive of the driving device. Since the diluted fertilizer solution and the original fertilizer solution are initially in a stratified state, the driving device drives the movable rod 52 to move in a linear direction from the diluted fertilizer solution to the original fertilizer solution, thereby quickly mixing the diluted fertilizer solution and the original fertilizer solution.

[0047] In this embodiment, the base 51 can be located on the inner bottom wall of the corresponding box, and then a linear drive component such as an electric cylinder is installed on the outer bottom wall of the box. The linear drive component is connected to the moving rod 52, thereby driving the moving rod 52 to move in a linear direction. Among them, the blades 53 are distributed in at least two layers along the axial direction of the moving rod 52, and each layer has at least two blades 53 evenly distributed, thereby ensuring the stirring effect.

[0048] It should be noted that different crops require different fertilizer spraying methods at different stages, such as drip irrigation and large-area spraying.

[0049] In some examples, the spray heads are connected to the supply box via quick-connect couplings. In this embodiment, all spray heads are connected to the supply box via flexible hoses; that is, both the first spray head 32 and the second spray head 33 are connected to the flexible hoses via quick-connect couplings. The quick-connect couplings allow for quick replacement of the type of the first spray head 32 and / or the second spray head 33, thereby meeting current spraying needs.

[0050] In some examples, the spray heads are slidably connected to the frame via mounting brackets. Specifically, in this embodiment, the first spray head 32 and the second spray head 33 are slidably connected to the guide frame 31 via mounting brackets 35. The mounting bracket 35 includes a support base 351 and an adjusting rod 352 rotatably connected to the support base 351. The end of the adjusting rod 352 away from the support base 351 is provided with a fixing member 353 for mounting the spray head. During actual fertilizer application, the position of the spray head relative to the corresponding ridge can be adjusted promptly by moving the corresponding mounting bracket 35 according to operational needs. The angle of the spray head can then be adjusted by rotating the adjusting rod 352, thereby achieving precise fertilizer application and ensuring the effectiveness of fertilizer application.

[0051] Among them, the fastener 353 can be a structure that enables detachment, such as a clamp, so as to facilitate the replacement of the spray head.

[0052] In some examples, the walking component 4 includes at least two walking wheels arranged side by side to stably support the frame 1 under the assistance of external forces.

[0053] In this embodiment, the first traveling wheel 41 is fixedly installed on the sliding frame 43, and a preset distance is provided between the first traveling wheel 41 and the positioning leg 42. By fixing the first traveling wheel 41, it can be used as an adjustment reference, reducing adjustment steps. Then, by setting the distance between the positioning leg 42 and the first traveling wheel 41, the positioning leg 42 can stably support the frame 1. In some special cases of soil depression, the first traveling wheel 41 and the positioning leg 42 can cooperate to jointly support the frame 1.

[0054] In this embodiment, the positioning leg 42 is stored inside the frame 1 when it is not deployed, so as to avoid interference with other components.

[0055] In some examples, the traveling wheels include a telescopic frame 411 and a support wheel 412 mounted on the end of the telescopic frame 411, with the end of the telescopic frame 411 away from the support wheel 412 connected to a sliding frame 43. That is, in this embodiment, both the first traveling wheel 41 and the second traveling wheel 44 include a telescopic frame 411 and a support wheel 412 mounted on the end of the telescopic frame 411, with the end of the telescopic frame 411 away from the support wheel 412 connected to the sliding frame 43. By providing the telescopic frame 411, the height of the frame 1 relative to the support surface can be adjusted in a timely manner according to the height of the ridge, improving the adaptability of the device to different terrains and avoiding damage to the ridge.

[0056] In some examples, the positioning leg 42 includes a rotating frame 421 and a support pad 422 located at the end of the rotating frame 421. The rotating frame 421 is rotatably connected to the frame 1. The support pad 422 has rigid protrusions 423 distributed on the side away from the rotating frame 421. When using the positioning leg 42 to support the frame 1, the rotating frame 421 is adjusted to be vertical to the support surface. The cross-section of the support pad 422 can be much larger than the cross-section of the rotating frame 421, thereby increasing the contact area between the positioning leg 42 and the support surface. The rigid protrusions 423 can be made of metal or rubber and are formed in the shape of an inverted frustum so that they can be at least partially inserted into the soil, thereby improving the contact stability between the positioning leg 42 and the support surface and ensuring the stability of the frame 1.
