Single-head up-and-down reciprocating semi-rotary pesticide spraying device

Abstract

The application discloses a single-head up-and-down reciprocating semi-rotation pesticide spraying device and belongs to the technical field of agricultural machinery, which comprises a pesticide box, an arc hollow frame body, a transmission mechanism, a displacement mechanism and a pesticide spraying mechanism. The rotation of a roller drives the rotation of the transmission mechanism, and then drives the rotation of the displacement mechanism. The pesticide spraying mechanism is connected with the displacement mechanism. When the displacement mechanism moves, the pesticide spraying mechanism is driven to move. In the movement process of the pesticide spraying mechanism, with the change of the movement track, when the pesticide spraying mechanism sprays pesticides from top to bottom, the upper surface of grape leaves is sprayed first. When the pesticide spraying mechanism sprays pesticides from bottom to top, the lower surface of grape leaves is sprayed. The full-range uniform spraying of grape leaves is realized. Meanwhile, when the grape leaves are sprayed from the side, the problem that the lower grape leaves close to grape stems cannot be sprayed is reasonably solved.

Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, and in particular relates to a single-head reciprocating semi-rotary spraying device. Background Technology

[0002] There are many varieties of grapes, about 8,000 worldwide. They can be broadly divided into two categories: wine grapes and table grapes. However, only a dozen or so grapes are commonly used for winemaking.

[0003] Different pesticides are needed to spray grapevines during different seasons to prevent pest infestation. In small-scale planting areas, small sprayers can be used manually, while large-scale sprayers are required for larger planting areas. Currently available sprayers include blower-type sprayers and negative ion sprayers. Blower-type sprayers use a fan to atomize the pesticide, achieving a spraying effect. Negative ion sprayers utilize the adsorption effect of negative ions to achieve better pesticide absorption.

[0004] In existing technologies, the nozzles of sprayers and spraying devices are positioned in a fixed manner, which prevents pesticides from being sprayed onto the top and bottom of the grapevines. Furthermore, this can easily cause leaf shading, resulting in uneven spraying. In other words, during spraying, the pesticide can only be sprayed onto the top of the grape leaves, not the bottom. Additionally, the fixed coverage area of ​​the spray nozzle makes it easy for the top and bottom of the grapevines to be missed. Moreover, due to the growth characteristics of grape leaves, during spraying, the lower part of the lower grape leaf (the inward-facing part) may not be sprayed due to leaf shading. Summary of the Invention

[0005] In view of this, it is necessary to provide a single-head reciprocating semi-rotary spraying device that meets the spraying needs of grapevines.

[0006] The solution of the present invention to the aforementioned technical problem is:

[0007] A single-head reciprocating semi-rotary spraying device includes a spray tank, an arc-shaped hollow frame, a transmission mechanism, a displacement mechanism, and a spraying mechanism. The spray tank is located at the top of the arc-shaped hollow frame. A C-shaped mounting part with a sliding groove is provided inside the arc-shaped hollow frame. Rollers are provided at the bottom of the arc-shaped hollow frame. The transmission mechanism, displacement mechanism, and spraying mechanism are located within the cavity of the arc-shaped frame. One end of the transmission mechanism is connected to the roller, and the other end is connected to the displacement mechanism. The displacement mechanism moves by means of the rotation of the transmission mechanism. One side of the spraying mechanism slides in cooperation with the sliding groove, and the other side is connected to the displacement mechanism. The movement of the displacement mechanism drives the spraying mechanism to spray the grapevines in a semi-circular rotation.

[0008] Preferably, the transmission mechanism includes a first transmission member, a second transmission member, and a third transmission member. The first transmission member is vertically arranged, and one end of the first transmission member meshes with the roller. The second transmission member is horizontally arranged and meshes with the other end of the first transmission member. The third transmission member is vertically arranged, and one end of the third transmission member meshes with the other end of the second transmission member. The other end of the third transmission member is connected to the displacement mechanism.

[0009] Preferably, the first transmission component includes a first double-ended bevel gear and a first fixing component. One end of the first double-ended bevel gear meshes with the roller, and the other end is connected to the second transmission component. The first fixing component is connected to the bow-shaped hollow frame, and the first double-ended bevel gear is rotatably mounted on the first fixing component.

[0010] Preferably, the second transmission component includes a second double-ended bevel gear and a second fixing component. One end of the second double-ended bevel gear meshes with the other end of the first double-ended bevel gear, and the other end meshes with the third transmission component. The second fixing component is connected to the bow-shaped hollow frame, and the second double-ended bevel gear is rotatably mounted on the second fixing component.

[0011] Preferably, the third transmission component includes a bevel gear, a connecting rod, a first boss transmission component, and a third fixing component. The inclined surface of the bevel gear meshes with the other end of the second double-headed bevel gear. The plane of the bevel gear is connected to one end of the connecting rod. The other end of the connecting rod meshes with the first boss transmission component. The third fixing component is connected to the bow-shaped hollow frame, and the connecting rod is rotatably mounted on the third fixing component.

[0012] Preferably, the displacement mechanism includes a fourth transmission component, a pair of limiting components, and a belt. The fourth transmission component is symmetrically arranged directly below the third transmission component. The pair of limiting components are symmetrically and rotatably arranged on the bow-shaped hollow frame, located at the two corners of the C-shaped mounting portion. The belt is movably connected to the fourth transmission component, the pair of limiting components, and the transmission mechanism to drive the belt to move.

[0013] Preferably, the fourth transmission component includes a second boss transmission component and a fourth fixing component, wherein the second boss transmission component meshes with the belt, and the fourth fixing component is connected to the bow-shaped hollow frame.

[0014] Preferably, the spraying mechanism includes a rotating component, a spray tube, a spray head, and a limiting link. The limiting link is disposed on one side of the rotating component and is slidably engaged with the slide groove. The rotating component moves along the path of the slide groove through the sliding engagement of the limiting link and the slide groove. The path of the slide groove is adapted to the belt. The belt is provided with a driving plate. A driving rod is disposed on the other side of the rotating component. The driving rod is rotatably connected to the driving plate. The belt drives the rotating component to move along the path of the slide groove through the driving plate and the driving rod. The spray tube passes through the rotating component and is slidably engaged. The spray head is disposed on the spray tube and is located outside the bow-shaped hollow frame.

[0015] Preferably, both sides of the bow-shaped hollow frame are provided with C-shaped mounting parts, transmission mechanisms, displacement mechanisms, and spraying mechanisms.

[0016] Beneficial effects: The single-head reciprocating semi-rotary spraying device includes a medicine box, an arched hollow frame, a transmission mechanism, a displacement mechanism, and a spraying mechanism. The rotation of the roller drives the rotation of the transmission mechanism, which in turn drives the rotation of the displacement mechanism. The spraying mechanism is connected to the displacement mechanism. When the displacement mechanism moves, it drives the spraying mechanism to move. During the movement of the spraying mechanism, as the trajectory changes, when the spraying mechanism sprays from top to bottom, it first sprays the upper part of the grape leaves. When the spraying mechanism sprays from bottom to top, it sprays the lower part of the grape leaves, achieving uniform spraying of the grape leaves from all directions. At the same time, when spraying from the side, it effectively solves the problem that the lower part of the grape leaves near the grape stem cannot be sprayed with medicine when the grape leaves are close together.

Detailed Implementation

[0034] To more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0035] Please refer to Figures 1 to 16 A single-head reciprocating semi-rotating spraying device includes a spray tank 10, an arc-shaped hollow frame 20, a transmission mechanism 30, a displacement mechanism 40, and a spraying mechanism 50. The spray tank is located at the top of the arc-shaped hollow frame 20. A C-shaped mounting part 201 is provided inside the arc-shaped hollow frame 20, and a sliding groove 203 is provided inside the C-shaped mounting part 201. A roller 202 is provided at the bottom of the arc-shaped hollow frame 20. The transmission mechanism 30, the displacement mechanism 40, and the spraying mechanism 50 are located inside the cavity of the arc-shaped hollow frame 20. One end of the transmission mechanism 30 is connected to the roller 202, and the other end is connected to the displacement mechanism 40. The displacement mechanism 40 moves by means of the rotation of the transmission mechanism 30. One side of the spraying mechanism 50 slides in cooperation with the sliding groove 203, and the other side is connected to the displacement mechanism 40. The movement of the displacement mechanism 40 drives the spraying mechanism 50 to spray the grapevines in a semi-circular rotation.

[0036] The medicine tank 10 is located at the top of the bow-shaped hollow frame 20. The roller 202 located at the bottom of the bow-shaped hollow frame 20 enables the movement of the single-head reciprocating semi-rotating spraying device. The transmission mechanism 30, the displacement mechanism 40, and the spraying mechanism 50 are located within the internal cavity of the bow-shaped hollow frame 20. During the rotation of the roller 202, the transmission mechanism 30 and the roller 202 are meshed. In this design, the roller 202 and the transmission mechanism 30 are meshed on inclined planes. The roller 202 has a rotating shaft, and one end of the rotating shaft has a bevel gear. When the roller 202 rotates, the bevel gear also rotates, and consequently, the transmission mechanism 30 rotates along with the roller 202, thus transmitting power. At this time, as the transmission mechanism 30 rotates, the displacement mechanism 40 connected to it also moves, and the spraying mechanism 50 connected to it also moves along with it. During this movement, the spraying mechanism 50, driven by the displacement mechanism 40, moves along the trajectory of the slide groove 203 provided on the C-shaped mounting part 201. At this time, the movement trajectories of the displacement mechanism 40 and the spraying mechanism 50 are the same. When the single head... When the reciprocating semi-rotary spraying device is in use, the displacement mechanism 40 drives the spraying mechanism 50 to form a closed spraying loop during its movement. As the spraying mechanism 50 moves from top to bottom, it forms a closed spraying path, and its spraying trajectory is: downward-left-upward-left. When the spraying mechanism 50 is at its highest position, it sprays downwards, with the pesticide sprayed above the grape leaves. As the spraying mechanism 50 moves, its spraying direction gradually changes from downwards to left. When the spraying mechanism 50 reaches its lowest position... As the spraying mechanism 50 rotates, its spraying direction gradually changes from left to up. Then, as the spraying mechanism 50 rotates, its spraying direction changes back to left. This has the advantage that the spraying mechanism 50 continues to spray the grapevines while changing direction, avoiding situations where some grapevines cannot be sprayed due to the change in direction. At the same time, spraying along this trajectory ensures that both the upper and lower surfaces of the grape leaves are sprayed with pesticide. Furthermore, when spraying from the side, the spraying mechanism 50 avoids situations where grape leaves that are touching each other cannot be sprayed, achieving uniform spraying of the grape leaves from all directions.

[0037] Furthermore, the transmission mechanism 30 includes a first transmission member 301, a second transmission member 302, and a third transmission member 303. The first transmission member 301 is vertically arranged, and one end of the first transmission member 301 meshes with the roller 202. The second transmission member 302 is horizontally arranged and meshes with the other end of the first transmission member 301. The third transmission member 303 is vertically arranged, and one end of the third transmission member 303 meshes with the other end of the second transmission member 302. The other end of the third transmission member 303 is connected to the displacement mechanism 40.

[0038] One end of the transmission mechanism 30 is connected to the roller 202, and the other end is connected to the spray head 503. The transmission mechanism 30 serves as a transmission mechanism between the roller 202 and the spray head 503, enabling the spray head 503 to move as the roller 202 rotates. To prevent the transmission mechanism 30 from bending due to external forces during use and to improve transmission efficiency, the transmission mechanism 30 is configured as a first transmission member 301, a second transmission member 302, and a third transmission member 303. During use, the first transmission member 301, the second transmission member 302, and the third transmission member 303 cooperate with each other to drive the spraying mechanism 50 to move and achieve the purpose of spraying.

[0039] In one specific embodiment, the first transmission member 301 includes a first double-ended bevel gear 3011 and a first fixing member 3012. One end of the first double-ended bevel gear 3011 meshes with the roller 202, and the other end is connected to the second transmission member 302. The first fixing member 3012 is connected to the bow-shaped hollow frame 20, and the first double-ended bevel gear 3011 is rotatably mounted on the first fixing member 3012.

[0040] In order to prevent the first transmission component 301 from shifting during use, a first fixing component 3012 is provided. The first double-headed bevel gear 3011 is fixed to the bow-shaped hollow frame 20 by the first fixing component 3012. The fixing method can be selected according to the specific use scenario, such as connecting rod fixing. In this case, a fixing block is selected. The fixing block is connected to the bow-shaped hollow frame 20, and the first double-headed bevel gear 3011 is sleeved on the fixing block, thereby realizing the use of the first transmission component 301. At the same time, the first double-headed bevel gear 3011 is a conventional selection in existing accessories.

[0041] In another specific embodiment, the second transmission member 302 includes a second double-ended bevel gear 3021 and a second fixing member 3022. One end of the second double-ended bevel gear 3021 meshes with the other end of the first double-ended bevel gear 3011, and the other end meshes with the third transmission member 303. The second fixing member 3022 is connected to the bow-shaped hollow frame 20, and the second double-ended bevel gear 3021 is rotatably mounted on the second fixing member 3022.

[0042] In order to prevent the second transmission component 302 from shifting during use, a second fixing component 3022 is provided. The second double-headed bevel gear 3021 is fixed to the bow-shaped hollow frame 20 by the second fixing component 3022. The fixing method can be selected according to the specific application scenario, such as connecting rod fixing. In this case, a fixing block is selected. The fixing block is connected to the bow-shaped hollow frame 20, and the second double-headed bevel gear 3021 is sleeved on the fixing block, thereby realizing the use of the second transmission component 302. At the same time, the second double-headed bevel gear 3021 is a conventional selection in existing accessories.

[0043] In a preferred embodiment, the third transmission component 303 includes a bevel gear 3031, a connecting rod 3032, a first boss transmission component 3033, and a third fixing component 3034. The bevel gear 3031 meshes with the other end of the second double-headed bevel gear 3021, and the other end is connected to one end of the connecting rod 3032. The other end meshes with the first boss transmission component 3033. The third fixing component 3034 is connected to the bow-shaped hollow frame 20, and the connecting rod 3032 is rotatably mounted on the third fixing component 3034.

[0044] To better enable the spraying mechanism 50 to rotate and spray pesticides, the third transmission member 303 is shaped as a bevel gear 3031, a connecting rod 3032, a first boss transmission member 3033, and a third fixing member 3034. During use, the bevel gear 3031 meshes with the other end of the second double-headed bevel gear 3021. The connecting rod 3032 connects to the first boss transmission member 3033, thereby driving the first boss transmission member 3033 to rotate. One end of the spraying mechanism 50 contacts the upper surface of the first boss transmission member 3033. When the first boss transmission member 3033 is in operation, it drives the spraying mechanism 50 to rotate, thereby driving the spray head 503 to rotate and spray pesticides. The third fixing member 3034 is also used to prevent the third transmission member 303 from shifting during use, and it fixes the third transmission member 303 to the bow-shaped hollow frame 20.

[0045] In one specific embodiment, the displacement mechanism 40 includes a fourth transmission member 401, a pair of limiting members 402, and a belt 403. The fourth transmission member 401 is symmetrically arranged directly below the third limiting member. The pair of limiting members 402 are symmetrically and rotatably arranged on the bow-shaped hollow frame 20, located at the two corners of the C-shaped mounting part 201. The belt 403 is connected to the fourth transmission member, the pair of limiting members 402, and the movable rod of the transmission mechanism 30, and is used to drive the belt 403 to move.

[0046] The fourth transmission member 401 is correspondingly arranged with the third transmission member 303 and connected by the belt 403, forming a closed motion loop. To avoid collisions between the belt 403 and the fourth transmission member 401 and the third transmission member 303 during the motion, a limiting member 402 is provided. The limiting member 402 keeps the belt 403 away from the fourth transmission member 401 and the third transmission member 303, ensuring that the belt 403 will not collide with the fourth transmission member 401 and the third transmission member 303 when it rotates.

[0047] In specific applications, due to the action of the third transmission component 303, the fourth transmission component 401, and the limiting component 402, the spraying mechanism 50 will have two semi-circular arcs during its movement. This is why the spraying direction of the spraying head 503 changes to the left during spraying. At the same time, this arrangement avoids contact between the spraying mechanism 50, the transmission mechanism 30, and the displacement mechanism 40, reducing unnecessary wear on the single-head reciprocating semi-rotary spraying device and extending its service life.

[0048] Furthermore, the fourth transmission component 401 includes a second boss transmission component 4011 and a fourth fixing component 4012. The second boss transmission component 4011 meshes with the belt 403, and the fourth fixing component 4012 is connected to the bow-shaped hollow frame 20.

[0049] To better enable the spraying mechanism 50 to rotate and spray pesticides, the fourth transmission member 401 is configured as a fourth bevel gear, a fourth connecting rod, a second boss transmission member 4011, and a fourth fixing member 4012. When configured, the shapes of the fourth bevel gear, fourth connecting rod, second boss transmission member 4011, and fourth fixing member 4012 are the same as those of the third transmission member 303. During use, the fourth bevel gear meshes with the other end of the bevel gear and connects to the second boss transmission member 4011 via the fourth connecting rod, thereby driving the rotation of the second boss transmission member 4011. One end of the spraying mechanism 50 contacts the upper surface of the second boss transmission member 4011. When the second boss transmission member 4011 is in contact, it drives the spraying mechanism 50 to rotate, thereby driving the spray head 503 to rotate and spray pesticides. The fourth fixing member 4012 is also used to prevent the fourth transmission member from shifting during use, fixing the fourth transmission member to the bow-shaped hollow frame 20.

[0050] Furthermore, the spraying mechanism 50 includes a rotating component 501, a pesticide tube 502, a spray head 503, and a limiting link 504. The limiting link 504 is disposed on one side of the rotating component 501 and slides with the slide groove 203. The sliding engagement of the limiting link 504 with the slide groove 203 causes the rotating component 501 to move along the path of the slide groove 203. The path of the slide groove 203 is adapted to the belt, and the belt is provided with a drive plate 40. 31. A driving rod 5011 is provided on the other side of the rotating component 501. The driving rod 5011 is rotatably connected to the driving plate 4031. The belt drives the rotating component 501 to move along the path of the slide groove 203 through the driving plate 4031 and the driving rod 5011. The medicine tube 502 passes through the rotating component 501 and is slidably engaged. The spray head 503 is provided on the medicine tube 502 and is located outside the bow-shaped hollow frame 20.

[0051] The rotating component 501 is connected to the grooves opened on the displacement mechanism 40 and the bow-shaped hollow frame 20. When the displacement mechanism 40 moves, the spraying mechanism 50 moves with the displacement mechanism 40 under the action of the driving rod 5011 and the driving plate 4031. The medicine tube 502 is sleeved in the rotating component 501. When the displacement mechanism 40 moves, the medicine tube 502 and the rotating component 501 will be displaced in a horizontal position. At this time, the rotating component 501 will move along the sliding groove 5021 provided on the medicine tube 502. In a specific setting, a steel ball is installed corresponding to the sliding groove 5021. When the medicine tube 502 rotates 90 degrees, the steel ball can position the medicine tube 502 to ensure the spraying direction of the spray head 503.

[0052] In a preferred embodiment, the bow-shaped hollow frame 20 is symmetrically provided with a C-shaped mounting part 201, a transmission mechanism 30, a displacement mechanism 40 and a spraying mechanism 50 on both sides.

[0053] When spraying pesticides, it is necessary to spray both sides of the grapevine. At this time, C-shaped mounting parts 201, transmission mechanism 30, displacement mechanism 40 and spraying mechanism 50 are symmetrically arranged on both sides of the bow-shaped hollow frame 20 to meet the spraying needs of the entire grapevine.

[0054] The specific operating steps of the single-head reciprocating semi-rotary spraying device are as follows: The hollow arched frame 20 has a C-shaped mounting portion 201 inside, and a sliding groove 203 is provided within the C-shaped mounting portion 201. The spraying mechanism 50 can spray pesticides along the path of the sliding groove 203 (the sliding groove 203 is a closed C-shaped structure, and the spraying mechanism 50 can perform cyclical movement along the path of the sliding groove 203). During use, the transmission mechanism 30 meshes with the rollers on the hollow arched frame 20, thereby driving the transmission mechanism 30 to move, realizing the transmission of force. Without energy consumption, as the transmission mechanism 30 rotates, the first boss transmission member 3033 also rotates. The belt 403 connects the first boss transmission member 3033 and the second boss transmission member 4011, forming a semi-circular closed-loop spraying path along the slide groove 203 (the belt is sleeved on the first boss transmission member 3033 and the second boss transmission member 4011). When the transmission mechanism 30 moves, the belt 403 moves along with the transmission mechanism 30, thereby driving the spraying mechanism 50 to move. The limiting linkage 504 is disposed on one side of the rotating member 501, facilitating the movement of the rotating member 501 along the path of the slide groove 203. The path of the slide groove 203 is adapted to the shape of the belt 403. During use, a driving plate 4031 is disposed on the belt, and a driving rod 5011 is disposed on the other side of the rotating member 501. The driving rod 5011 is rotatably connected to the driving plate 4031. When the belt 403 rotates, the driving plate 4031 and the driving rod 5011 drive the rotating member 501 along the slide groove 203. The path movement of the groove 203 drives the spraying mechanism 50 to move, and the pesticide tube 502 passes through the rotating member 501 and is slidably engaged. When there is relative displacement between the rotating member 501 and the pesticide tube 502, in order to ensure that the length of the spray head 503 extending outside the bow-shaped hollow frame 20 does not change, a sliding groove 5021 can be opened along the length direction of the pesticide tube 502. Under the action of the sliding groove 5021, it is convenient for the rotating member 501 and the pesticide tube 502 to undergo relative displacement. At the same time;The spraying mechanism 50 forms a closed spraying path, and the spraying movement trajectory of the spray head 503 is: downward-left-upward. When the spray head 503 is at its highest position, it sprays downward, at which point it is in the first position, where the pesticide is sprayed above the grape leaves. As the spraying mechanism 50 moves, the spraying direction of the spray head 503 gradually changes from downward to left, from the first position to the second position, and then from the second position to the third position. At the third position, the spraying direction of the spray head 503 is close to left. Then, the spraying mechanism 50 moves downward along the belt 403 to the fourth position, where the spray head 503 sprays to the left. Finally, when the spray head 503 moves to the lowest position, it reaches the fifth position, where it sprays upward, completing one spraying cycle. Then, as the belt 403 rotates, the spraying mechanism 50 moves from below to above the hollow arched frame 20. During this movement, the spraying direction of the spray head 503 is upward-left-down, forming a closed-loop spraying path.

[0055] In specific usage, the contact status of the rotating component 501 with the first boss transmission component 3033 and the second boss transmission component 4011 is as follows: when the spraying mechanism 50 moves from top to bottom, the right side of the rotating component 501 contacts the first boss transmission component 3033; when the spraying mechanism 50 moves from bottom to top, the left side of the rotating component 501 contacts the second boss transmission component 4011. At the same time, when the spraying mechanism 50 rotates with the belt 403, the rotating component 501 and the pesticide tube 502 will also move relative to each other. When the spray head 503 moves downward, the rotating component 501 will move closer to the end away from the spray head 503; when the spray head 503 moves upward, the rotating component 501 will move closer to the end where the spray head 503 is located.

[0056] The single-head reciprocating semi-rotating spraying device provides the following effects during spraying: Under the action of the belt 403 and the slide 203, the spraying mechanism 50 forms a closed-loop spraying trajectory within the arched hollow frame 20. When the spraying mechanism 50 is at its uppermost position, the spraying direction is from top to bottom, and the pesticide falls on the upper surface of the grape leaves. As the spraying mechanism 50 moves downward with the rotation of the belt 403, the spraying head 503 changes its spraying angle, gradually changing from downward spraying to leftward spraying. At this point, the spraying angle of the spraying head 503 is perpendicular to the grapevine, allowing it to spray the grape leaves from the side. Then, as the belt 403 rotates, the spraying direction of the spray head 503 changes to upward spraying, thus spraying the lower surface of the bottom grape leaves. As the spray head 503 moves upward, it will spray the grape leaves again from the side to complete a closed-loop spraying operation. In this spraying method, spraying from top to bottom ensures that the pesticide falls evenly on the upper surface of each grape leaf, and spraying from bottom to top ensures that the pesticide falls evenly on the lower surface of each grape leaf. At the same time, when the spray head 503 sprays from the side, it effectively solves the problem of the grape leaves being close to each other and the lower part of the grape leaves near the grape stem not being sprayed with pesticide, so that the entire grape leaf can be sprayed with pesticide.

[0057] Meanwhile, to prevent the first transmission component 301, the second transmission component 302, the third transmission component 303, and the fourth fixing component 4012 from shaking and shifting position during use, the first fixing component 3012, the second fixing component 3022, the third fixing component 3034, and the fourth fixing component 4012 are used to connect the first transmission component 301, the second transmission component 302, and the third transmission component 303 to the bow-shaped hollow frame 20 during installation. Of course, any conventional technical means can be used for fixing. The first fixing component 3012, the second fixing component 3022, and the third fixing component 3034 will not be described in detail. During the transmission process of the first transmission component 301, the second transmission component 302, and the third transmission component 303, the rotation of the transmission mechanism 30 is achieved by the contact of the inclined surfaces on the bevel gears.

Those skilled in the art will understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present invention are still within the scope of the invention.

Claims

1. A single-head reciprocating semi-rotation spraying device, characterized in that: The device includes a medicine box, an arched hollow frame, a transmission mechanism, a displacement mechanism, and a spraying mechanism. The medicine box is located on the top of the arched hollow frame. A C-shaped mounting part with a sliding groove is provided inside the arched hollow frame. Rollers are provided at the bottom of the arched hollow frame. The transmission mechanism, displacement mechanism, and spraying mechanism are located inside the cavity of the arched hollow frame. One end of the transmission mechanism is connected to the roller, and the other end is connected to the displacement mechanism. The displacement mechanism moves by means of the rotation of the transmission mechanism. One side of the spraying mechanism slides in cooperation with the sliding groove, and the other side is connected to the displacement mechanism. The movement of the displacement mechanism drives the spraying mechanism to spray the grapevines in a semi-circular rotation. The transmission mechanism includes a first transmission member, a second transmission member, and a third transmission member. The first transmission member is vertically arranged, and one end of the first transmission member meshes with the roller. The second transmission member is horizontally arranged and meshes with the other end of the first transmission member. The third transmission member is vertically arranged, and one end of the third transmission member meshes with the other end of the second transmission member. The other end of the third transmission member is connected to the displacement mechanism. The first transmission component includes a first double-ended bevel gear and a first fixing component. One end of the first double-ended bevel gear meshes with the roller, and the other end is connected to the second transmission component. The first fixing component is connected to the bow-shaped hollow frame, and the first double-ended bevel gear is rotatably mounted on the first fixing component. The second transmission component includes a second double-ended bevel gear and a second fixing component. One end of the second double-ended bevel gear meshes with the other end of the first double-ended bevel gear, and the other end meshes with the third transmission component. The second fixing component is connected to the bow-shaped hollow frame, and the second double-ended bevel gear is rotatably mounted on the second fixing component. The third transmission component includes a bevel gear, a connecting rod, a first boss transmission component, and a third fixing component. The inclined surface of the bevel gear meshes with the other end of the second double-headed bevel gear. The plane of the bevel gear is connected to one end of the connecting rod. The other end of the connecting rod meshes with the first boss transmission component. The third fixing component is connected to the bow-shaped hollow frame, and the connecting rod is rotatably mounted on the third fixing component. The spraying mechanism's movement trajectory is: downward-left-upward-left. When the spraying mechanism is at its highest point, it sprays downwards, with the pesticide sprayed onto the grape leaves. As the spraying mechanism moves, its spraying direction gradually changes from downward to left. When it reaches its lowest point, the spraying direction gradually changes from left to upward. Then, as the spraying mechanism rotates again, its spraying direction changes back to left. This design ensures continuous spraying of the grapevines while changing direction, preventing some grapevines from being missed due to the change in direction. Simultaneously, this trajectory ensures that both the upper and lower surfaces of the grape leaves are sprayed with pesticide. Furthermore, when spraying from the side, it prevents overlapping grape leaves from being missed, achieving even spraying of the grape leaves from all directions.

2. The single-head reciprocating semi-rotary spraying device as described in claim 1, characterized in that: The displacement mechanism includes a fourth transmission component, a pair of limiting components, and a belt. The fourth transmission component is symmetrically arranged directly below the third transmission component. The pair of limiting components are symmetrically and rotatably arranged on the bow-shaped hollow frame, located at the two corners of the C-shaped mounting part. The belt is movably connected to the fourth transmission component, the pair of limiting components, and the transmission mechanism to drive the belt to move.

3. The single-head reciprocating semi-rotary spraying device as described in claim 2, characterized in that: The fourth transmission component includes a second boss transmission component and a fourth fixing component.
