Description

Technical Field

[0001] This utility model relates to the field of agricultural planting machinery technology, and in particular to a spraying device for intercropping tobacco with corn. Background Technology

[0002] Intercropping flue-cured tobacco with corn is a highly efficient intercropping model. The core of this model is to intercrop corn between the tobacco rows during the mid-to-late stages of tobacco growth, fully utilizing land, sunlight, water, and fertilizer resources to achieve a double harvest in one season, increasing yield per unit area. It is widely applicable in tobacco-growing areas of southern my country. This model typically involves sowing corn between the tobacco rows at a certain spacing 40-50 days after transplanting (when the tobacco enters its peak growth period). This model can increase land utilization by more than 30%, while corn stalks can be returned to the field to improve the soil, achieving complementary benefits between tobacco and grain and efficient resource utilization. It is an important planting method for ensuring food security and increasing farmers' income in tobacco-growing areas. When intercropping corn with tobacco, pesticides need to be sprayed. Therefore, a pesticide spraying device specifically designed for intercropping flue-cured tobacco with corn is used to spray both crops.

[0003] However, the existing equipment has the following shortcomings: When using the existing equipment, the spray support plate is generally fixed, making it difficult to accurately spray pesticides according to the height of the crops, resulting in the problem that the equipment is difficult to adapt to the height of the crops for spraying.

[0004] Therefore, we propose a spraying device for using flue-cured tobacco as corn to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the spraying height of equipment is fixed, making it difficult to spray pesticides on crops at different heights. This invention proposes a pesticide spraying device for intercropping tobacco with corn.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a spraying device for overlying tobacco with corn, comprising a mounting frame, a power unit, a water tank, a support plate, a connecting plate, and an adjusting device. The power unit is mounted on the upper end of the mounting frame, the water tank is mounted on the upper end of the mounting frame, the support plate is mounted on one end of the mounting frame, the connecting plate is mounted on the lower end of the support plate, and the adjusting device is mounted on one side of the mounting frame. The adjusting device includes a support frame and a sliding hole. The sliding hole is formed on the side of the support frame, and the support frame is fixedly connected to the side of the mounting frame. A limiting rod is fixedly connected to the end of the support plate near the support frame. A limiting groove is formed on the surface of the sliding hole. A sliding rod is fixedly connected to the end of the limiting rod away from the support plate. The sliding rod is slidably connected inside the sliding hole, and the limiting rod is inserted into the limiting groove.

[0007] Furthermore, a fixing block is fixedly connected to the end of the slide rod away from the limiting rod, and a movable ring is sleeved and connected to the surface of the slide rod. By setting the fixing block, the first spring can be limited, reducing the situation where the first spring is difficult to compress and generate kinetic energy when the equipment moves.

[0008] Furthermore, a first spring is sleeved and connected to the surface of the slide rod.

[0009] Furthermore, one end of the first spring is fixedly connected to one end of the moving ring, and the end of the first spring away from the moving ring is fixedly connected to the surface of the fixed block. The first spring is provided to facilitate the application of a restoring force to the slide rod.

[0010] Furthermore, an auxiliary component is fixedly provided at the upper end of the support plate. The auxiliary component includes a first mounting plate and a cylinder. The first mounting plate is fixedly connected to the upper end of the support plate, and the cylinder is fixedly connected to the upper end of the first mounting plate. The telescopic end of the cylinder is fixedly connected to the upper end of the connecting plate. By providing the cylinder, the connecting plate can be moved.

[0011] Furthermore, a second mounting plate is fixedly connected to the end of the cylinder away from the first mounting plate, and a connecting rod is fixedly connected between the first mounting plate and the second mounting plate.

[0012] Furthermore, an installation head is fixedly connected to the upper end of the cylinder.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting an adjustment device, the height of the support plate can be effectively adjusted, which plays the role of adjusting the support plate. This reduces the problem that existing equipment generally uses a fixed spray support plate, which makes it difficult to accurately spray pesticides according to the height of crops, resulting in the equipment being unable to adapt to the height of crops for spraying. This adjustment device realizes the rapid adjustment of the height of the equipment's spray support plate, making it convenient for the equipment to adapt to crops of different heights for spraying, and improving the practicality of the equipment.

[0014] 2. In this utility model, by setting an auxiliary component, the height of the connecting plate can be effectively adjusted, which reduces the problem of uneven spraying when spraying pesticides on intercropped corn and tobacco, which is difficult to achieve when the corn is intercropped with tobacco at different heights. This auxiliary component realizes the misalignment between the connecting plate and the support plate, which facilitates the uniform spraying of two crops at different heights and improves the uniformity of equipment use.

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Please see Figures 1-5 This utility model provides a technical solution: a spraying device for overlying corn with flue-cured tobacco, including a mounting frame 1, a power unit 2, a water tank 3, a support plate 4, a connecting plate 5 and an adjusting device 6. The power unit 2 is installed at the upper end of the mounting frame 1, the water tank 3 is installed at the upper end of the mounting frame 1, the support plate 4 is installed at one end of the mounting frame 1, and the connecting plate 5 is installed at the lower end of the support plate 4.

[0020] Mounting frame 1 serves as the overall support frame for the equipment, welded from high-strength alloy tubing, ensuring a stable structure capable of supporting the weight of components such as power unit 2 and water tank 3. Power unit 2 provides power for equipment movement and pesticide delivery, driving the equipment across the field and simultaneously powering the pump within water tank 3. Water tank 3 is a pesticide storage container made of corrosion-resistant plastic, with a volume adapted to field operation needs, facilitating the carrying of sufficient pesticide solution. Power unit 2 drives the internal drive unit of mounting frame 1, rotating the wheels on its side. Support plate 4 serves as the mounting carrier for the upper spraying components, with nozzles mounted at the bottom for spraying taller crops such as corn. Connecting plate 5 serves as the mounting carrier for the lower spraying components, offset from support plate 4, suitable for spraying shorter crops such as tobacco. Adjustment device 6 adjusts the height of support plate 4 to accommodate crops at different growth stages, ensuring spraying accuracy.

[0021] The specific settings and functions of its adjustment device 6 and auxiliary components 7 will be described in detail below.

[0022] In this embodiment: the adjusting device 6 is installed on one side of the mounting frame 1. The adjusting device 6 includes a support frame 61 and a sliding hole 62. The support frame 61 is the fixed base of the adjusting device 6 and is rigidly connected to the mounting frame 1, providing sliding support for the sliding rod 65 and the limiting rod 64. The sliding hole 62 is the moving channel of the sliding rod 65, ensuring that the sliding rod 65 moves in a straight line, thereby driving the support plate 4 to rise and fall smoothly. The sliding hole 62 is opened on the side of the support frame 61. The support frame 61 is fixedly connected to the side of the mounting frame 1. The end of the support plate 4 near the support frame 61 is fixedly connected to the limiting rod 64. The surface of the sliding hole 62 is opened with a limiting groove 63. The end of the limiting rod 64 away from the support plate 4 is fixedly connected to the sliding rod 65. The sliding rod 65 is slidably connected inside the sliding hole 62. The limiting rod 64 is inserted and connected inside the limiting groove 63.

[0023] Specifically, a fixing block 68 is fixedly connected to the end of the slide rod 65 away from the limiting rod 64, and a moving ring 66 is sleeved and connected to the surface of the slide rod 65.

[0024] In this embodiment, by setting a fixing block 68, the first spring 67 can be limited, reducing the difficulty of the first spring 67 to compress and generate kinetic energy when the device moves.

[0025] Specifically, a first spring 67 is sleeved and connected to the surface of the slide rod 65. The first spring 67 is a compression spring made of high-elasticity spring steel, which has long-lasting elasticity and can provide stable restoring force.

[0026] Specifically, one end of the first spring 67 is fixedly connected to one end of the moving ring 66, and the end of the first spring 67 away from the moving ring 66 is fixedly connected to the surface of the fixed block 68. The first spring 67 is provided to facilitate the application of a restoring force to the slide rod 65.

[0027] In this implementation scheme: An auxiliary component 7 is fixedly installed on the upper end of the support plate 4. The auxiliary component 7 includes a first mounting plate 71 and a cylinder 72. The first mounting plate 71 is the fixed base of the cylinder 72 and is stably connected to the support plate 4. The cylinder 72 is the power source for the lifting and lowering of the connecting plate 5. It can precisely control the lifting and lowering height of the connecting plate 5 and realize the misalignment adjustment with the support plate 4. The first mounting plate 71 is fixedly connected to the upper end of the support plate 4, and the cylinder 72 is fixedly connected to the upper end of the first mounting plate 71. The telescopic end of the cylinder 72 is fixedly connected to the upper end of the connecting plate 5.

[0028] In this embodiment, the connecting plate 5 can be moved by setting cylinder 72.

[0029] Specifically, a second mounting plate 74 is fixedly connected to the end of the cylinder 72 away from the first mounting plate 71, and a connecting rod 73 is fixedly connected between the first mounting plate 71 and the second mounting plate 74.

[0030] Specifically, the upper end of cylinder 72 is fixedly connected to mounting head 75.

[0031] Working principle: When using the equipment, the user first pours the prepared pesticide solution into the water tank 3 and tightens the lid to prevent leakage; then pushes the equipment or starts the power unit 2 to drive the equipment to the field where flue-cured tobacco and corn are intercropped; after starting the equipment, the booster pump inside the water tank 3 starts to work, and delivers the pesticide solution through the water pipeline to the nozzle installed at the lower end of the support plate 4 and the connecting plate 5; after the pesticide solution is atomized by the nozzle, it is sprayed on the surface of the crop to complete the spraying operation. When the height of the support plate 4 needs to be adjusted according to the crop's growth height, the user pulls the support plate 4, causing the limiting rod 64 and the sliding rod 65 to move. As the sliding rod 65 moves, it compresses the first spring 67 via the fixing block 68, generating elastic force. Then, the limiting rod 64 moves away from the limiting groove 63, and the moving support plate 4 causes the sliding rod 65 to move within the sliding hole 62, adjusting the height of the support plate 4. After the support plate 4 is released, the first spring 67 resets, causing the limiting rod 64 to insert into the limiting groove 63, mechanically locking the support plate 4. By setting the adjustment device 6, the height of the support plate 4 can be effectively adjusted, thus reducing the difficulty of accurately spraying pesticides according to the crop height, which is common in existing equipment where the spraying support plate 4 is fixed. This adjustment device 6 enables rapid adjustment of the height of the spraying support plate 4, facilitating the equipment's adaptation to different crop heights and improving its practicality.

[0032] By setting auxiliary component 7, when adjusting the height of the connecting plate 5, the user activates cylinder 72 to move the connecting plate 5 at the lower end of the support plate 4. By setting auxiliary component 7, the height of the connecting plate 5 is effectively adjusted, which reduces the problem of uneven spraying when spraying pesticides on intercropped corn and tobacco, where the corn is intercropped with tobacco and the two crops are at different heights. This auxiliary component 7 achieves the misalignment of the connecting plate 5 and the support plate 4, making it easier for the equipment to spray the two crops at different heights evenly and improving the uniformity of equipment use.

[0033] The above description discloses only one or more preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of the present utility model still fall within the scope of the present utility model.
