Description

Technical Field

[0001] This utility model belongs to the field of seedling spraying technology, and specifically relates to a forestry seedling pest control spraying device. Background Technology

[0002] During the seedling cultivation process, it is essential to pay close attention to the pest control process. Different diseases and pests may occur at different growth stages of seedlings. Therefore, spraying pesticides to kill pests is an important step in the entire seedling cultivation process.

[0003] A mobile pest control device, with prior art publication number CN 220630799 U, uses a spray head for spraying. The applicant argues that this technical solution has structural defects, making it difficult to reliably achieve the desired effect. The document mentions that "the moving block 705 is connected to the outer wall of the rotating rod 703, and the moving block 705..." The inner wall is threadedly connected to the outer wall of the rotating rod 703. The rotation of the rotating rod 703 causes the moving block 705 to move up and down on the outer wall of the rotating rod 703, thereby adjusting the height of the spray head 706. However, this solution cannot guarantee stable implementation. First, the fixed block and the rotating rod are threadedly connected, allowing them to rotate relative to each other. Second, there is no other structure in the solution to restrict or limit the axial rotation of the fixed block. Therefore, when the rotating shaft rotates, the fixed block and spray head are prone to swaying due to the forward movement of the moving vehicle, causing the fixed block to rotate or swing arbitrarily. Furthermore, if the rotation is reversed, the spray head height adjustment will not be achieved, and the spray range may even become unstable. These are all consequences of the fixed block's free rotation, thus failing to achieve the desired stable technical effect. Therefore, the above solution has technical defects.

[0004] Furthermore, in the agricultural pest and disease control spraying device disclosed in CN 222148783 U, a double-ended water pipe with a cover is used for spraying pesticides or water. When spraying pesticide, the cover must first be folded down to cover both ends of the double-ended water pipe, lowering it to prevent pesticide or water spraying and to accurately target the field to be irrigated. However, the spraying range of this method is quite limited, making it relatively inefficient for pest and disease control in large seedling bases. Secondly, atomized spraying not only ensures uniform spraying but also improves pesticide utilization, but the method of using a cover over the water pipe ends in this solution makes it difficult to achieve atomized spraying. Therefore, the above solution has drawbacks in its application for pesticide spraying.

[0005] Therefore, the applicant provides a spraying solution that can control the spraying range and improve the spraying effect. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a forestry seedling pest control spraying device that can control the spraying range to achieve atomized spraying, accurately spraying onto the seedlings and improving the spraying effect.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A forestry seedling pest control spraying device includes a carrier, a battery pack, a pesticide tank, a spraying mechanism, and a control mechanism; the carrier carries the battery pack, the pesticide tank, and the spraying mechanism, the spraying mechanism is located at one end of the carrier, and the control mechanism is located on the spraying mechanism.

[0009] The spraying mechanism includes a first rotating shaft, a gear set, a support plate, a second rotating shaft, a first spray pipe, a second spray pipe, an electric actuator, a mounting plate, and a support column. The mounting plate is fixedly connected to the support column, and the support column is fixedly connected to the carrier platform. The first rotating shaft is rotatably connected to one end of the mounting plate. The first rotating shaft is provided with a rotatably connected gear set, a fixedly connected first missing gear, and a fixedly connected first fixing block. The first missing gear has a missing tooth portion. The gear set includes a second missing gear and a first gear fixedly connected to each other. The second missing gear and the first missing gear have the same structure. There is a pair of support plates, which are located on the upper and lower sides of the mounting plate. One end of the support plate is fixedly connected to the first rotating shaft, and the second rotating shaft is rotatably connected to the other end of the support plate. The second rotating shaft is provided with a fixedly connected second gear and a second fixing block.

[0010] One end of the first spray pipe is fixed to the first fixing block, and one end of the second spray pipe is fixed to the second fixing block. One end of the first spray pipe and the second spray pipe are provided with pipe joints, which can be connected to each other to transmit liquid medicine.

[0011] The electric actuator is fixedly mounted on the mounting plate. A mounting block is provided at the top end of the electric actuator shaft. The mounting block is slidably connected to a limiting strip, which is fixed to the mounting plate. The mounting block is provided with a first rack and a second rack. The first rack is provided with a toothed portion and a limiting portion, with the limiting portion located at the front end of the first rack. When the toothed portion meshes with the teeth of the first missing gear, it can drive the first rotating shaft to rotate. When the missing toothed portion contacts and engages with the limiting portion, it stops the rotation of the first rotating shaft and the first missing gear, and in this case, it can still continuously push the first rack to slide. The second rack has the same structural features as the first rack, except that the toothed portion of the second rack is located at the front end of the second rack.

[0012] The control mechanism includes a third rack, a U-shaped frame, a C-shaped frame, a second lead screw, and a fixed frame. The fixed frame is fixedly connected to a support plate, and the third rack meshes with a first gear and a second gear. The U-shaped frame is fixedly connected to the third rack. The C-shaped frame is slidably connected to the U-shaped frame and provides support. The C-shaped frame is provided with a limiting shaft, which is located within the gap of the U-shaped frame. The C-shaped frame is provided with a fixed second guide shaft and a rotating second lead screw. The second lead screw is threadedly connected to the fixed frame, and the second guide shaft is slidably connected to the fixed frame. The third rack can slide along the C-shaped frame, and the limiting shaft restricts the sliding direction.

[0013] Preferably, the battery pack is protected by a protective cover; the vehicle is equipped with handrails, and the battery pack supplies power to the various electrical components.

[0014] Preferably, the medicine tank is equipped with a medicine outlet pipe, which is connected to the pipe interface of the first spray pipe; the medicine tank is also equipped with a water pump to draw the medicine liquid.

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] This solution features a controllable spraying mechanism, which includes an electric push rod and corresponding first and second racks, gear sets, and other structural features. The push rod's top shaft can be extended and retracted to rotate the first and second rotating shafts, allowing the first and second spraying pipes to be deployed relative to each other for spraying or retracted after spraying. Compared to existing solutions in the prior art, the spraying range is significantly increased, and after the first and second spraying pipes are retracted, they facilitate movement or transportation, demonstrating strong adaptability.

[0017] Secondly, by utilizing the teeth and limiting parts on the first and second racks in conjunction with the first missing gear, the second missing gear, and the third rack, the first and second rotating shafts can be rotated sequentially, thereby enabling the first and second spraying pipes to be opened or closed in an orderly manner.

Figure 5 and Figure 6 As shown.

[0035] The second rack 59 has the same structural features as the first rack 58, except that the teeth 7 of the second rack 59 are located at the front end of the second rack 59; for example Figure 7 As shown.

[0039] A forestry seedling pest control spraying device, the working process of which is as follows:

[0040] The electric actuator 57 controls the first rack 58 and the second rack 59 to slide along the limiting bar 572, thereby driving the first rotating shaft 51 and the second rotating shaft 54 ​​to rotate; thereby driving the support plate 53 to rotate around the first rotating shaft 51 as the axis, opening the first spray pipe 55, and further rotating the second rotating shaft 54 ​​to open the second spray pipe 56, thus satisfying the working state of spraying.

[0041] Based on the structural features of this embodiment: First, rotating the second lead screw 64 causes the third rack 61 to mesh with the first gear 522 and the second gear 542; when the electric push rod 57 retracts and pulls the mounting block 571, the first spray pipe 55 and the second spray pipe 56 are opened successively. First, the teeth 7 on the first rack 58 mesh with the first missing tooth 512, driving the first rotating shaft 51 to rotate, causing the first spray pipe 55 and the support plate 53 to rotate. At this time, the limiting part 8 of the second rack 59 contacts the missing tooth part of the second missing tooth 521, causing the gear set 52 to stop; then the mounting block 571 is pulled again. 1. The teeth 7 of the second rack 59 mesh with the teeth of the second missing gear 521, driving the gear set 52 to rotate. At this time, the limiting part 8 of the first rack 58 touches the missing tooth part of the first missing gear 512, causing the first rotating shaft 51 to stop rotating. At this time, the first gear 522 on the gear set 52 rotates. Through the meshing state of the third rack 61 with the first gear 522 and the second gear 542, the second rotating shaft 54 ​​is driven to rotate, thereby unfolding the second spray pipe 56. This changes the first spray pipe 55 and the second spray pipe 56 from the retracted state to the unfolded state, expanding the spraying range and facilitating transportation and movement.
